Abstract：

Objective To summarize our experience and assess the feasibility and safety of transanal endorectal pull-through and laparoscopic subtotal colectomy for Hirschsprung's disease and allied disorder (HAD). Methods From March to December 2010,8 infants and children with long segment Hirschsprung's disease or/and allied disorder underwent Soave pull-through procedures under laparoscopic guidance. We modified this technique by mobilizing the whole colon via rectal muscular sleeve approach under laparoscopic vision, then transanal endorectal pull-through to complete the subtotal colectomy. Results All procedures were completed successfully. Single-port access laparoscope was introduced through the umbilicus in 6 cases and through a small incision after mobilized colostomy in 2 cases. The average operative time was 178 ± 23 min (range 155 to 240 min). The period of the full bowel action was 1-2 day. One infant developed postoperative intestinal obstruction that required open exploration. They were followed-up for 6 months (range 2-10 months). The bowel movement frequency was reduced from 5-15 per day postoperatively to 3-5 per day after 2 months. The clinical outcomes were excellent with no stool incontinence or constipation. Conclusions Transanal Soave pull-through subtotal colectomy with simple laparoscopic guidance is a safe, effective and feasible procedure, with minimal invasion,and good cosmetic result.

Abstract：

Objective To evaluate the efficacy of pelvic floor muscle exercise for the treatment of fecal incontinence after Soave procedure for Hirschsprung's disease. Methods Twenty four patients who had Soave procedure for Hirschsprung's disease and presented fecal incontinence after surgery were recruited in this study. They were 14 males and 10 females, aged from 6 to 13 years old. Eighteen children who had normal defecation after Soave procedure were selected as controls. All the subjects had manometry to measure resting anal canal pressure, squeeze pressure, and rectal sensation.All the patients had two weeks biofeedback therapy during their stay in hospital. After being discharged, they were taught and prescribed to do pelvic floor muscle exercise at home. Results Of the children with fecal incontinence, the resting anal canal pressure, squeeze pressure and rectal sensation were ( 18. 9 ± 6. 2 ) mmHg, ( 179. 9 ± 17. 8) mmHg, (45. 4 ± 9. 4) ml, respectively. Compared with the controls, the resting anal canal pressure was lower [(18. 9±6. 2) mmHg vs (44. 5 ± 11.1) mmHg].But no difference of squeeze pressure and rectal sensation was found between the 2 groups [(179. 9 ±17. 8)mmHg vs (177. 7 ± 15. 9) mmHg, (45.4 ± 9. 4)ml vs (50. 0 ± 10. 1)ml]. Three patients dropped out of the therapy. Five patients stopped the exercise after the first year. The other 21 who kept exercise improved their defecation function. Their resting anal canal pressure, squeeze pressure and rectal sensation were (35. 4 ± 8. 7)mmHg, (195. 3 ± 15.0)mmHg and (45. 9 ± 8. 4)ml, respectively. Conclusions The dysfunction of internal anal sphincter might be the main cause for fecal incontinence after Soave procedure. Pelvic floor muscle training is helpful to improve the defecation function of the patients.     

Prevention and treatment strategies for esophageal stenosis after thoracoscopy for type Ⅲ esophageal atresia北大核心CSCD

Objective To explore the roles of esophageal stenosis control strategies in children with esophageal atresia (EA). Methods Retrospective analysis was conducted for clinical data of 56 children with type Ⅲ EA undergoing thoracoscopy from January 2017 to December 2022.There were 30 boys and 26 girls.The clinical types were ⅢA (n=12) and ⅢB (n=11) in group A. Birth weight was (2573.26±112.77) gram and operative age (31.70±5.86) hours.Eight cases had concurrent congenital heart disease (CHD). And 33 patients received traditional postoperative observation (group B). The clinical types were ⅢA (n=18) and ⅢB (n=15) in group B. Birth weight was (2 598.79±94.88) gram and operative age (37.00±7.15) hour.Six cases had concurrent CHD.Preoperative profiles and postoperative recovery of two groups were compared along with differential efficacy between the prevention and treatment strategy after comparing EA and traditional management mode. Results No statistically significant inter-group differences existed in operative age (P=0.593), body weight (P=0.863) or proportion of CHD (P=0.438). One-stage surgery was performed for repairing tracheoesophageal fistula and esophageal reconstruction.Later they were cured and discharged with regular follow-ups.The incidence of postoperative anastomotic stenosis was 26.09%(6/23) in group A versus 60.61%(20/33) in group B. The inter-group difference was insignificant (P=0.125). There were 0 cases (0%) of anastomotic leakage in group A versus 3 cases in group B (9.09%)(P=0.001). Average dilation frequency was[(0.61±0.27) vs (2.00±0.41), P=0.014]and incidence of postoperative refractory stenosis[0(0%) vs 4(12.12%), P=0.001]. The differences were statistically significant. Conclusions Perioperative comprehensive management plays some roles in the prevention and treatment of esophageal stricture after EA thoracoscopy.The clinical outcomes are satisfactory. © 2023 Chinese Medical Journals Publishing House Co.Ltd..

Abstract：

Objective To study the clinical outcomes of anorectoplasty and external anal sphincterplasty via posterior approach with Y-shaped incision to repair intermediate and low anorectal malformation complicated with rectal perineal fistula in children. Methods Twenty four patients with intermediate and low anorectal malformation complicated with rectal perineal fistula were enrolled in this study. Via the posterior approach, a Y-shaped incision (＜3 cm) was made to expose the lower rectum and fistula. The external anal sphincter was identified and dissected at the posterior aspect of the lower rectum. The external anal sphincterplasty was performed by overlapping the ends of the muscle around the lower rectum. The rectal perineal fistula was resected and anorectoplasty was performed. Results All surgeries were successfully performed. Voluntary bowel movement and fecal continence was restored on 23 patients after surgery. One 5 years old patient still had constipation. Mild incision infection was found on 1 patient, and was cured after opening the incision and draining the pus. No fecal incontinence or anastomotic stricture was noted. Conclusions Compared with Pena surgery, anorectoplasty and external anal sphincterplasty via posterior approach with Y-shaped incision is less complicated and invasive to repair intermediate and low anorectal malformation complicated with rectal perineal fistula. By using this procedure, better sphincter shape and fecal function is achieved on patients.

Abstract：

Objective To summarize the experience of diagnosis and treatment of intractable constipation in children with repaired anorectal malformation.Methods Between August 2005 and July 2010,23 children with a history of anorectal malformation (ARM) repair were diagnosed with intractable constipation,and underwent surgical treatment at this center.The patients,including 10 boys and 13 girls,underwent primary surgeries to repair low or intermediate type of ARMs.Their ages at the primary surgery ranged from 3 days to 6 years old.Physical examinations found normal appearance of anus on 14 children including 1 with rectourethral fistula,anus antelocation on 6,cicatricial retraction of anus on 2,and anal stricture on 1.The positive barium enema revealed the dilated distal colon and rectum without transition zones,and delayed barium transit time.The patients' age at the second surgery ranged from 1 year and 2 months to 15 years and 8 months old.Results Dilated distal colon and rectum,with increased intestinal wall and mesentery thickness as well as proliferated blood vessels,was found during surgery on all patients.However,no transition zone was observed.To remove the dilated intestine,transanal Soave procedure was performed on 13 children,and the other 10 underwent abdomino-perineal Soave procedure including 1 had additional ileostomy.Besides the megacolon resection,9 patients also underwent anoplasty,and rectourethral fistula was also repaired on 1 patient.At the distal end of the removed intestine,pathological examination revealed ganglion cells in 15 patients,and no ganglion cells in 8 patients.Hypertrophy,degeneration and derangement of the intestinal smooth muscle cells were also observed.After reoperation,patients' anal function was graded as 5 or 6 according to Lizheng's anal function scoring criteria.Conclusions Intractable constipation after ARM repair is usually caused by acquired megacolon.It can be cured by megacolon resection.     

腹腔镜辅助肛门直肠成形术致后尿道憩室的预防措施探讨CSCD

Objective To explore the preventive measures of posterior urethral diverticulum (PUD) after laparoscopic assisted anorectoplasty (LAARP). Methods From August 2013 to December 2018, perioperative and postoperative clinical data were reviewed for 6 children with anorectal malformation (ARM) developing PUD after LAARP. PubMed database was searched for all published English literatures of PUD after ARM surgery from 2000 to 2021. Since international naming of PUD is not standardized, there are two major names, i. e. remnant of original fistula and PUD. Thus retrieval keywords were anorectal malformation, remnant of original fistula and PUD. Results The diagnostic age was 17 months to 5 years after LAARP. The clinical manifestations included mucuria, recurrent urinary tract infection and dysuria, etc. Computed tomography (CT) and retrograde urethrography revealed prerectal cyst. A total of 13 articles were retrieved, reporting 102 cases of PUD after ARM surgery. The age was 1 — 44 years and the diameter of PUD 3 —70 mm. The major clinical symptoms were frequent urination, dysuria, recurrent urinary tract infection, urinary calculi, hematuria and urinary incontinence, etc. Some non-symptomatic cases were only discovered accidentally during follow-ups. ARM procedures included LAARP (n = 36), posterior sagittal anorectopasty (PSARP,n = 15), abdominoperineal pull-through (n=15) and APP (n=50). Conclusion PUD is a rare complication after ARM surgery. And potential risks of PUD may be minimized by strengthening perioperative managements and improving surgical techniques. © 2022, Journal of Clinical Pediatric Surgery. All rights reserved.     

加速康复外科技术在肛门闭锁并直肠前庭瘘中的应用CSCD

Objective To explore the efficacy and safety of enhanced recovery after surgery (ERAS) in children with anal atresia and rectal vestibular fistula. Methods From January 2017 to October 2021, prospective review was conducted for 50 children with anal atresia and rectal vestibular fistula undergoing transanal analoplasty. They were randomized into two groups of ERAS and non-ERAS (n =25 each). ERAS group received enema once in the morning of operation day, oral 12.6% carbohydrate liquid 2 h pre-operation, intraoperative heat preservation, target-oriented rehydration ,no indwelling catheter post-operation, postoperative analgesia and other new measures; non-ERAS group had traditional perioperative treatment. Blood glucose at the beginning of anesthesia, blood glucose 24 h post-operation, white blood cell count ( WBC), C-reactive protein (CRP), time of initial exhaust and defecation post-operation, amount of intraoperative infusion, time of postoperative intravenous infusion ,time of postoperative hospitalization, expenditure of hospitalization incidence of complications and readmission rate at Day 30 post-discharge were compared between two groups. Results No significant inter-group differences existed in average age, weight, preoperative WBC, CRP, hemoglobin, albumin, prealbumin or blood glucose at admission. Blood glucose at the beginning of anesthesia in ERAS and non-ERAS groups was (4.92±0.50) and (4.53 ±0.42) mmol/L, blood glucose (5.03 ±0.66) and (5.96±41.18) mmol/L at 24 h post-operation. WBC at 24h post-operation (9.97 3.24) x 10°/L and (8.28 ±3.51) x 10°/L;CRP at 24 h post-operation (3.63±4.00) and (9.03±15.77) mg/L;initial postoperative exhaust and defecation time (12.1 ±6.4) and (14.0 ±9.3) h;intraoperative infusion volume (83.1 ±32.2) and (136. 1±68.4) mL;postoperative intravenous infusion time (4.68 ±1.25) and (6.6 ±1.68) days; postoperative hospital stay (7.12 ± 1.56) and (10.56 ±3.58) days; hospitalization expense (13 314. 34 ±2 856.86) and (16 088.69 ±3 282.34) CNY ;complications occurred (n =3,12%) and (n =6,24%) ;overall satisfaction was 88% and 60%. Both groups were cured and discharged and there was no re-admission within 30 days post-discharge. No inter-group differences existed in initial exhaust or defecation time, WBC and CRP at 24 h post-operation (P >0.05).In nonERASgroup, blood glucose declined at the beginning of anesthesia while postoperative blood glucose level rose with statistical difference (P <0. 05) ; overall satisfaction of ERAS group was higher than that of non-ERAS group with statistical difference (P lt; 0.05). Conclusion Conceptual application of ERAS is both safe and effective in children with anal atresia with rectovestibular fistula. It can effectively shorten the average time of hospital stay, curtain the length of postoperative hospitalization and lower hospitalization expenditure. A wider popularization is worthy. © 2022, Journal of Clinical Pediatric Surgery. All rights reserved.     

低出生体重食管闭锁患儿预后因素的研究

Objective To investigate the prognostic factors of survival rate after repair of esophageal atresia (EA) and/or tracheoesophageal fistula (TEF). Methods The clinical data of the 101 patients underwent TEF/EA repair between January 1999 and December 2008 at this center were retrospectively reviewed. The patients were divided into low-birth-weight group (29 patients, birth-weight＜2 500 grams) and normal-birth-weight group (72 patients, birth-weight＞2. 5 kg). The possible prognostic factors were retrospectively analyzed including patients status, the incidence of preoperative and intraoperative critical events, postoperative complications, postoperative mechanical ventilation time,stress hyperglycemia and survival rate. Logistic regression analysis was employed to predict the prognostic factors of the survival rate after repair of EA and/or TEF. Results Of the 29 low-birth-weight EA patients, the survival rate was significantly lower than that of the normal birth weight patients (75.9% vs 92. 3% ,P = 0. 027) ,and the survival rate positively correlated with the birth weight (r=0. 946,P= 0. 015). The incidence of preoperative and intraoperative critical events and postoperative complications in low-birth-weight EA patients were significantly higher than those of the normal birth weight patients (67. 7% vs 32. 9% ,P = 0. 002; 70% vs 26%, P = 0. 001 ). The morbidity of anastomotic stricture and leak was higher, and postoperative mechanical ventilation time was longer compared with the normal birth weight patients (P = 0. 001 ). The survival rate of the patients had postoperative stress hyperglycemia was lower than that of patients without stress hyperglycemia (93. 6% vs 81.0%,P = 0. 024) ,and the survival rate negatively correlated with the severity of postoperative stress hyperglycemia (r = - 0. 931, P = 0. 022). Conclusions Low-birth-weight and postoperative stress hyperglycemia are the prognostic factors of survival rate after repair of EA and/or TEF.     

Integrated management during the perinatal period for total anomalous pulmonary venous connection北大核心CSCD

Objective To evaluate the clinical effectiveness of integrated management during the perinatal period for fetuses diagnosed with total anomalous pulmonary venous connection (TAPVC) by prenatal echocardiography. Methods Clinical data of 64 cases of TAPVC fetuses diagnosed by prenatal echocardiography and managed with integrated perinatal care in Qingdao Women and Children's Hospital from January 2017 to December 2021 were retrospectively analyzed. Integrated perinatal care included multidisciplinary collaboration among obstetrics, fetal medicine, ultrasound, pediatric cardiology, pediatric anesthesia, and neonatology. Results Among the 64 TAPVC fetuses, there were 29 cases of supracardiac type, 27 cases of intracardiac type, 2 cases of infracardiac type, and 6 cases of mixed type. Chromosomal analysis was performed in 42 cases, and no obvious abnormalities were found. Among the 64 TAPVC fetuses, 37 were induced labor, and 27 were followed up until term birth. Among the 27 TAPVC cases, 2 cases accepted palliative care, 2 cases were referred to another hospital for treatment and lost to follow-up, while the remaining 23 cases underwent primary repair surgery. One case died within 6 months after the operation due to low cardiac output syndrome, while the other 22 cases were followed up for (2.1±0.3) years with good outcomes (2 cases underwent a second surgery within 1 year after the first operation due to anastomotic stenosis or pulmonary vein stenosis). Conclusions TAPVC fetuses can achieve good outcomes with integrated management during the perinatal period. © 2023 Xiangya Hospital of CSU. All rights reserved.     

SOX10在先天性巨结肠相关性小肠结肠炎发病中的作用

目的 探讨SOX10、潘氏细胞发育及分泌防御素-5与先天性巨结肠相关性小肠结肠炎的关系.方法 收集50例先天性巨结肠病变肠管,根据术前是否发生小肠结肠炎分为HAFC组(n=14)和HD组(n=36),并以20例正常结肠标本作对照组.采用免疫组织化学方法观察结肠中防御素-5蛋白质表达、潘氏细胞发育情况以及SOX10蛋白质表达情况.采用实时荧光定量PCR技术检测防御素-5 mRNA及Sox 10 mRNA表达情况.结果 防御素-5在正常肠管中不表达,HAEC组和HD组在肠腺隐窝基底处呈不同程度阳性表达.但前者阳性区域平均光密度值明显增高(0.33±0.039比0.10±0.031,P＜0.05),HAEC组防御素-5mRNA亦呈显著增高趋势(2.72±0.80比0.78±0.21,P＜0.05).对结肠组织同层切片进行潘氏细胞特异性产物溶菌酶免疫组化染色发现,对照组肠管中除1例存在弱阳性外其他均无阳性表达.HD组和HAEC组结肠中同样在隐窝基底处存在溶菌酶阳性细胞,可鉴别为化生的潘氏细胞,但HAEC组在发生率(78.6%)和细胞个数(2.97±0.80)明显高于HD组(27.8%,0.43±0.85)(P＜0.05).SOX10免疫产物主要在结肠神经节细胞膜及胞浆中表达,对照组、HAEC组、HD组阳性区域的平均光密度值递减(0.75±0.041,0.61±0.048,0.35±0.025),差异具有统计学意义(P＜0.05),同时RT-PCR检测显示Sox10 mRNA在各组中的表达与蛋白质水平呈平行结果.结论 SOX10可能通过影响潘氏细胞发育及分泌防御素-5在先天性巨结肠相关性小肠结肠炎的发生发展中起一定作用.

Abstract：

Objective To study the expression of SOX10 and Human α-defensins-5(HD-5 )in Hirschsprung's disease associated enterocolitis(HAEC) and expore the possible relationship between SOX10 and HAEC.Methods Fifty pathological colons of Hirschsprung's disease (HD) were divided into HAEC group (n = 14) and HD group(n = 36) according to the presence of preoperative enterocolitis,Twenty normal colons as control group.The protein and mRNA expression of HD-5 and SOX 10 were measured by immunohistochemical staining and real-time quantitative PCR Results Normal colons did not express HD-5 but positive expression of HD-5 was detected at the base of the crypts of Lieberkuhn in HAEC and HD groups in different degree.The mean optical density of HD-5 immunohistochemical staining (0.33 ± 0.039 vs 0.10 ± 0.031 )and HD-5 mRNA expression (2.72 ± 0.80 vs 0.78 ± 0.21 ) in HAEC group was apparently higher than those in HD group(P＜0.05).The expression of lysozyme,a specific product by Paneth Cell,on sequential sections was negative in control group except one sample.In HAEC group and HD group,positive expression of lysozyme can be seen in the crypts of Lieberkuhn,where the cells can be identified as Metaplastic Paneth cell,but the incidence (78.6% vs 27.8%) and the number of cells 2.97 ± 0.80 vs 0.43 ± 0.85) in HAEC group were obviously higher than those in HD group(2.97 ± 0.80 vs 0.43 ± 0.85) (P＜0.05).SOX10 was mainly located in the plasmalemma and cytoplasm of ganglion cell and its mean optical density in control group (0.75 ±0.041 ),HAEC group (0.61 ± 0.048)and HD group(0.35 ± 0.025) were decrement,the difference between three groups were statistically significant (P＜0.05).Meanwhile,Sox10mRNA detected by real-time quantitative PCR indicated the parallel result.Conclusions SOX10 may be an important factor in the pathogenesis and development of HAEC.

Abstract：

Objective To evaluate the efficacy of modified Soave procedure combined with colon plication for the treatment of Hirschsprung's disease (HD) in children.Methods Between July 2005 and August 2009,32 HD patients of the plication group underwent modified Soave procedure combined with colon plication at this center.Another 32 patients who underwent modified Soave procedure were enrolled as the controls.The pathological examinations,follow-up,barium enema,anorectal manometry,and anorectal function were retrospectively reviewed and analyzed to evaluate the surgical efficacy.Results Of the 32 patients of the plication group,26 had normal ganglion cells at both ends of the dilated intestine,and decreased ganglia number and ganglia degeneration were found on the other 6 patients.However,among the 32 control patients,decreased ganglia number and ganglia degeneration was only found on 4 patients.Rectoscopy suggested that mucosa rugae caused by colon plication could eventually disappear half a year after the surgery.On patients' barium enema radiography,no dilated intestines were observed.No difference of the defecation function scores between the plication group and control group at 1 year after operation was found (defecation function score,6.6 ± 1.3 vs 6.8 ±1.2).Moreover,there was no difference of high pressure zone length (2.0 ± 0.7 cm vs 1.9 ± 0.6 cm),anal canal resting pressure (53.1 ± 3.9 mmHg vs 52 ± 4.7 mmHg) and sensation threshold (30～55 ml vs 35～60 ml) between the 2 groups 1 year after operation.Postoperative complications included anastomotic stenosis was noted on 1 patients of the placation group,1 of the plication group and 1 control patient had mild soiling.Conclusions Modified Soave procedure combined with colon plication improves the defecation function of the HD patients.     

腹腔镜下十二指肠吻合术治疗新生儿十二指肠梗阻

Objective To evaluate the feasibility and indication of laparoscopie duodenoduoden-ostorny for neonates with congenital duodenal obstruction- Methods From May 2004 to Feburary 2008,6 newborns with duodenal obstruction underwent exploratory laparoscopy. With a lower-pressure pneumoperitoneum of 5～8 mmHg and a suspending suture for right liver elevator, the procedure was performed using 3 cannulas of 3.3 mm to 5.5 mm diameter. Under the laparoscopic vision, the cause of duodenal obstruction was diagnosed and a sutured anastomosis was performed after the duodenum mo-bilized. Results Findings at laparoscopy included duodenal diaphragm in 3 cases,annular pancreas in 2 cases, and preduodenal portal vein in 1 case. Three cases with duodenal diaphragmatic stenosis were en-countered a partial excision of the diaphragm after vertical incision of the anterior part of duodenum followed laparoscopically by a transverse suture. A diamond-shaped side-to-side duodenoduodenal anas-tomosis was successfully carried out in 2 cases of annular pancreas through a laparoseopic approach, but a duodenojejunostomy was converted to mini-laparotomy during the laparoscopic course of a predu-odenal portal vein. The average operative time was 102 16.5 min (85～135 min). Visualization was ex-cellent, and there were no intraoperative complications. Feedings were started on postoperative day 3 to 5. All cases were on full feedings after 8 to 10 days. Follow-up upper gastrointestinal tests showed no evidence of stricture or obstruction. Conclusions The duodenoduodenostomy with laparoseopy can be performed in neonates securely and appropriated for a full-term newborn with tolerance CO2 pneumo-peritoneum. It provides an excellent and micro-invasive way to evaluate and treat congenital duodenal obstruction.     

口服氟康唑在预防早产儿深静脉置管时真菌感染中的临床意义

Objective With the widespread application of peripherally inserted central catheters (PICC) in neonatal intensive care unit (NICU), the incidence of invasive fungal infections increased significantly than ever. The present study aimed to explore the clinical significance of oral fluconazole in premature infants with gestational age ≤ 32 weeks and/or birth weight ≤ 1500 grams who had catheter insertions. Method This study enrolled 118 infants admitted between January 2006 and December 2007 who did not receive fluconazole prophylaxis (control group) and 106 infants admitted between January 2008 and June 2009 who received oral fluconazole prophylaxis (prophylaxis group). Statistical analyses were performed by using SPSS 11.5 software. The clinical characteristics and the risk factors for invasive fungal infection between the two groups were compared. Liver functions ( alanine transaminase, ALT and direct bilirubin) were monitored to evaluate the safety of fluconazole prophylaxis. Result Except for the proportion of infants bom via vaginal delivery in the control group (56/118, 47. 5% ) was significantly lower than that in prophylaxis group (69/106, 65.1%, P = 0.007), there were no significant significant differences in the demographics and other baseline clinical characteristics between the two groups. There were no significant differences in the risk factors for invasive fungal infection between the two groups either.Nine infants developed invasive fungal infection in control group (7. 6% ), while no invasive fungal infection was found in prophylaxis group (0%, P=0.01 ). Compared to infants in control group, those in prophylaxis group showed no significant changes in alanine transaminase ALT and direct bilirubin levels at 2 weeks and 4 weeks after fluconazole prophylaxis: the incidences of abnormal ALT and direct bilirubin levels were 8. 5%(10/118) and6.8% (8/118) in control group compared to 11.3% (12/106) and 8.5% (9/106) in prophylaxis group after 2 weeks ( P = 0. 47 and 0. 63 ); the incidences of abnormal ALT and direct bilirubin levels were 3.4% (4/118) and 3.4% (4/118) in control group compared to 5.7% (6/106) and 8.5%(9/106) in prophylaxis group after 4 weeks (P = 0. 62 and 0. 15). Conclusion For infants with PICC insertions and gestational ages at birth ≤32 weeks and/or low birth weight ≤ 1500 grams, oral fluconazole is effective to prevent invasive fungal infection. Oral fluconazole in premature infants neither affected the liver function, nor increased the incidence of cholestasis.

电针可下调缺氧缺血性脑损伤幼鼠大脑皮层硫化氢含量

Objective To establish hypoxic-ischemic brain damaged (HIBD) rat model,investigate whether H2S and cystathionine-β-synthase (CBS), the key enzyme for its generation, may be a mediator of electro-acupuncture(EA) stimulation treatment for HIBD. Methods Thirty-two healthy Sprague-Dawley neonatal rats were divided into four groups randomly: sham control group ( n = 8 ); sham + EA group ( n =8); HIBD control group ( n = 8); and HIBD + EA group ( n = 8 ). HIBD rat models were established on their 7-day-old. From the next day ,rats of sham + EA group and HIBD + EA group were electric stimulated 30 min daily for 14 d,BAIHUI and DAZHUI as the acupoints. Control ones were just fixed at the same time,without acupuncture. The rats were sacrificed on the 22 nd day, one day after the treatment course. Cortical H2S concentration was measured by sensitive sulphur electrode assay. The CBS protein expression was measured by western blot analysis and immunohistochemistry for localization. Results The concentration of cortical H2S in HIBD control group was (26. 83 ± 4. 31 ) nmol/mg protein, which was significantly higher than that of sham control group[(22. 78 ± 1.54) nmol/mg protein]( P ＜ 0. 01 ). The H2 S levels in HIBD + EA group and sham + EA group were ( 18.08 ± 2.71 ) nmol/mg protein and ( 18.91 ± 2. 78 ) nmol/mg protein, respectively. Compared with corresponding control group, they were much lower( P ＜ 0. 01 ). The expression of CBS protein in rats with EA stimulation decreased in cortex compared to corresponding control group( P ＜0. 05 ).Conclusion EA can down-resulate H2S/CBS pathway. This may be one of the mechanisms of how EA contributes to the recovery of brain damage.

Abstract：

Objective To identify the enteric nervous system (ENS) stem cells in intestinal mucosa of the patients with Hirschsprung's disease (HD). Methods Fifteen patients were pathologically diagnosed with Hirschsprung's disease. They underwent surgery to remove the aganglionic intestines.The removed intestines were collected for this study. Of the 15 patients, 8 were infants (age≤1 year)and 7 were toddlers (age＞ 1year). Two were long-segment HD, and 13 were short-segment HD.Three pieces of tissues were collected from the stenotic segment, transitional zone and dilated segment of the removed intestines. The intestines proximate to the dilated segment were selected as controls.Immunohistochemical staining of stem cell markers including SOX10, Nestin, TuJ1 and GFAP was performed to indentify the ENS stem cells in intestinal mucosa. The TBS buffer was used as the negative control of the primary antibody. The S-P method was applied to analyze the expressions of the 4stem cell markers through the intestine. Results The expressions of SOX10, Nestin, and TUJ1 in the mucosa of the transitional zone and dilated segment were strong. And scattered SOX10, Nestin, and TUJ1 positive cells were observed in the lamina propria. But most of the SOX10, Nestin, and TUJ1 positive cells located in mucosa closed to the muscularis mucosa. The expression of GFAP in the mucosa of the transitional zone and dilated segment was negative. The expressions of SOX10, Nestin,TUJ1 and GFAP in myenteric plexus were stronger than those of submucosal plexus (SOX10 expression, infant 50% vs 31.3%, toddler 35. 7% vs 21.4%; Nestin expression, infant 43. 8% vs 37. 5%,toddler 28. 6% vs 14. 2%; TUJ1 expression, infant 37. 5% vs 18. 5%; toddler 28. 6% vs 28. 6%;GFAP expression 25.0 % vs 18. 5 % ; toddler 57. 1% vs 35. 7 % ; P ＜ 0. 05 ). The expressions of SOX10, Nestin and TUJ1 were stronger in submucosal plexus than those in mucosa (SOX10 expression, infant 31.3% vs 25. 0%, toddler 21.4% vs 7. 1% ; Nestin expression, infant 25. 0% vs 18. 8%,toddler 14. 3% vs 14. 3%; TUJ1 expression, infant 18. 5% vs 12. 5 %, toddler 28. 6% vs 7. 1%; P＜0. 05). The expressions of SOX10 and Nestin in myenteric plexus of the dilated segment in infants were stronger than thoset in toddler (SOX10, 75. 0% vs 42. 8% ; Nestin, 62. 5% vs 42. 8%, P＜0. 05). The expressions SOX10 and Nestin in mucosa of the the dilated segment in infants were stronger than those in toddler (SOX10, 37. 5% vs 14. 3%; Nestin, 25. 0% vs 14. 3%, P＜0. 05). Conclusions The ENS stem cells may exist in the mucosa of the ganglionic intestines of HD patients, whichare scattered and mostly located in the mucosa near muscularis mucosa. In HD patients, the expressions of SOX10, Nestin, TUJ1 and GFAP in myenteric plexus are higher than those in submucosal plexus. However, the expressions of SOX10, Nestin, TUJ1 and GFAP in the submucosal plexus are higher than those in the mucous layer. The expressions of SOX10 and Nestin in mucosa of the dilated segment in infants are higher than those in toddlers, and it decreases with age. These observations suggest the ENS stem cells or precursor cells in the gut mucosa may be derived from the gut neural crest cells.     

Surgical options for esophageal stenosis in children北大核心CSCD

Objective To explore the clinical efficacy of progressive individualized options for esophageal stenosis (ES) in children. Methods From January 2017 to December 2022, retrospective review was conducted for 106 ES children with regular follow-ups. There were 59 boys and 47 girls with an age range of (3.00 ± 0. 75) year and a body weight of (9.00 ± 1. 25) kg. The causes were anastomotic (n: 58), corrosive (n: 47) and congenital (n: 1). Sequential treatments of direct balloon dilation under gastroscope, submucosal injection of drugs into esophagus, esophageal stenting and surgical procedures were applied. After interventions, degree of ES was observed by esophagography and gastroscopy along with dysphagia grade for evaluating clinical efficacy. Differences were compared by I or yr test. Results All of them were discharged uneventfully. After balloon dilatation, the outcomes were excellent under direct gastroscopic view alone (n: 55). Among 35 children with balloon dilation plus esophageal submucosal drug injection, the outcomes were excellent (n: 25) and esophageal stenting (n: 10). Among 25 children with esophageal stenting, the outcomes were excellent (n:21) and additional surgery (n: 4). Surgical procedures were performed with excellent outcomes (n:5). Conclusions The clinical outcomes progressive individualized options of direct visualization balloon dilation under gastroscope, balloon dilation plus submucosal injection of drugs into esophagus, esophageal stenting and surgical procedure are precise, convenient and efficacious for ES in children. © 2023 Chinese Medical Journals Publishing House Co.Ltd.

Early risk factors for death in neonates with persistent pulmonary hypertension of the newborn treated with inhaled nitric oxide北大核心CSCD

Objective To evaluate the early risk factors for death in neonates with persistent pulmonary hypertension of the newborn (PPHN) treated with inhaled nitric oxide (iNO). Methods A retrospective analysis was performed on 105 infants with PPHN (gestational age ≥34 weeks and age <7 days on admission) who received iNO treatment in the Department of Neonatology, Children's Hospital of Nanjing Medical University, from July 2017 to March 2021. Related general information and clinical data were collected. According to the clinical outcome at discharge, the infants were divided into a survival group with 79 infants and a death group with 26 infants. Univariate and multivariate Cox regression analyses were used to evaluate the risk factors for death in infants with PPHN treated with iNO. The receiver operating characteristic (ROC) curve was used to calculate the cut-off values of the factors in predicting the death risk. Results A total of 105 infants with PPHN treated with iNO were included, among whom 26 died (26/105, 24.8%). The multivariate Cox regression analysis showed that no early response to iNO (HR=8.500, 95%CI: 3.024-23.887, P<0.001), 1-minute Apgar score ≤3 points (HR=10.094, 95%CI: 2.577-39.534, P=0.001), a low value of minimum PaO2/FiO2 within 12 hours after admission (HR=0.067, 95%CI: 0.009-0.481, P=0.007), and a low value of minimum pH within 12 hours after admission (HR=0.049, 95%CI: 0.004-0.545, P=0.014) were independent risk factors for death. The ROC curve analysis showed that the lowest PaO2/FiO2 value within 12 hours after admission had an area under the ROC curve of 0.783 in predicting death risk, with a sensitivity of 84.6% and a specificity of 73.4% at the cut-off value of 50, and the lowest pH value within 12 hours after admission had an area under the ROC curve of 0.746, with a sensitivity of 76.9% and a specificity of 65.8% at the cut-off value of 7.2. Conclusions Infants with PPHN requiring iNO treatment tend to have a high mortality rate. No early response to iNO, 1-minute Apgar score ≤3 points, the lowest PaO2/FiO2 value <50 within 12 hours after admission, and the lowest pH value <7.2 within 12 hours after admission are the early risk factors for death in such infants. Monitoring and evaluation of the above indicators will help to identify high-risk infants in the early stage. © 2022 Xiangya Hospital of CSU. All rights reserved.
