新式阴道前、后壁联合修补术临床分析

目的探讨新式阴道前、后壁联合修补术治疗盆腔脏器脱垂(POP)的临床效果。方法选择2017年1月至2021年1月,于南京医科大学附属淮安第一医院接受手术治疗的120例POP患者为研究对象。根据采用的手术方式,将其分为研究组(n=60,采用新式阴道前、后壁联合修补术)及对照组(n=60,采用腹腔镜下全子宫双侧附件切除术+传统阴道前、后壁修补术)。采用独立样本t检验及χ^(2)检验,对2组患者一般临床资料,术中及术后情况进行统计学比较。本研究经南京医科大学附属淮安第一医院医学伦理委员会批准(审批文号:YX-P-2020-023-01)。所有患者知情同意并与之签署临床研究知情同意书。结果①2组POP患者年龄、人体质量指数(BMI)、产次、绝经者比例及POP脱垂程度比较,差异均无统计学意义(P>0.05)。②研究组POP患者手术时间、术中出血量、总住院时间、术后住院时间及住院费用分别为(88.0±30.6)min、(24.7±36.0)mL、(7.3±2.1)d、(4.6±1.4)d及(10727±1812)元,均短于或低于对照组的(118.0±33.4)min、(56.7±43.8)mL、(9.8±2.3)d、(6.4±1.6)d及(26318±3890)元,并且差异均有统计学意义(t=5.130、4.372、6.218、6.558、28.138,均为P<0.001)。2组POP患者术后3、6、12个月复发率构成比比较,差异无统计学意义(P>0.05)。结论新式阴道前、后壁联合修补术在不增加POP患者术后复发率的基础上,不仅能缩短手术时间、减少患者术中出血量,还可以缩短住院时间、减少住院费用,并且易于操作,适宜推广。

HPV genotyping in biopsies of HSIL and invasive cervical cancers in women living with HIV: A cohort- and a nested -case control study

ObjectiveTo characterize HPV genotype distribution in HSIL and ICC- biopsies, of WLWH, in Europe, as compared to HIV-negative women.DesignCohort- and nested -case control study.MethodWe characterized HPV genotype distribution by performing PCR on HSIL and ICC biopsies from WLWH (n = 170); 85 cases were compared to 85 HIV-negative matched controls. The proportion of patients that might be protected by HPV vaccines was estimated.ResultsAmong WLWH (median age 36 years-old, median duration of HIV infection 70,5 months, 79% under cART): the most frequently detected HPV were HPV16 (30%), HPV35 (16%), HPV58 (14,7%), HPV31 (13,5%), and HPV52 (11,7%). HPV16 was less frequently found in WLWH, originating from Central Africa (20,5%) compared to other African regions (35,5%) (p = 0,05) or world regions (38,8%) (p = 0,007). Multiple versus single high-risk HPV infections were associated with younger age (≤35 years)(odds ratio (OR) 2,65 (95%IC: 1,3–5,2,p = 0,002), lymphocyte CD4 count < 350 cells / µL (OR 2,7 (95%IC: 2–8,5; p = 0,005), use of cART for < 18 month OR 2,2 (95%IC: 1,1–4,5),p = 0,04) or a cumulative time with undetectable HIV viral load of less than 12 months (OR 4,2 (95%IC: 2–8.5,p = 0,001). HPV 31, 33 and 35 were more frequently detected in samples from WLWH than in HIV-negative controls (p < 0,05). The 9-valent vaccine would increase HPV protection, in HIV-positive and negative women (p < 0,001).ConclusionWLWH are more frequently infected with high-risk HPV other than 16 and 18 than HIV-negative ones. The use of 9-valent vaccine may prevent HSIL or ICC in up to 85% of the women. Adding HPV 35 to the HPV vaccine panel, might improve vaccine effectiveness in WLWH.     

Biofluid Aspects of Embryo Transfer

Embryo transfer (ET) is the last stage of extracorporal fertilization during which the embryo is placed in the uterine cavity with a medium-filled catheter 2–3 days after in vitro fertilization. While fertilization in the laboratory occurs at very high rates (>:90%), the overall success of the procedure (i.e., take home baby) is still very low (<25%) and assumed to be mainly due to implantation failure. A computational model was developed to simulate ET within the uterine cavity by a fluid-filled catheter inserted into a two-dimensional channel with oscillating walls. The results showed that the speed at which the embryos are injected from the catheter dominates the procedure and controls the velocity of their transport within the uterine cavity. ET at excessively high injection speeds may lead to ectopic pregnancies, while uterine peristalsis affects transverse dispersion only during injection at low injection speeds. The presence of the catheter within the uterus does not affect flow patterns downstream of its tip. The potential risks to implantation failure due to mechanical factors involved in the ET processes are discussed. © 2003 Biomedical Engineering Society. PAC2003: 8719-j, 8710+e     

Klinische und funktionelle Ergebnisse der abdominalen Rektopexie unter Verwendung verschiedener Fixierungsgrundlagen

Zusammenfassung 63 Patienten wurden wegen eines Rektumprolaps durch eine abdominale Rektopexie (Operationsverfahren nach Ripstein-Corman) therapiert. Als Rektopexienahtlagermaterial wurden lyophylisierte Dura-Streifen, ein Vicryl-Netz oder ein Dexon-Netz verwendet. 71,4% (n = 45 von 63) des Kollektivs konnten nachuntersucht wurden, der Nachbeobachtungszeitraum betrug im Mittel 52,5 Monate. Die postoperative verfahrensbedingte Mortalität betrug 0%, im 30-Tage-Intervall nur 1,6% wegen kardialer Komplikationen. Intraoperative Komplikationen traten in 4,7% der Fälle auf. Die postoperative Morbiditätsrate betrug 25,4% (n = 16 von 63), infektbedingte Komplikationen wurden in 12.7% (n = 8 von 63) der Fälle beschrieben, davon 1 Fall mit einer spontan ausgeheilten pelvikutanen Fistel. Ein Rektumprolapsrezidiv zeigte sich in 4,4% (n = 2 von 45) der Fälle (nur Dura-Rektopexie), ein Schleimhautprolaps trat bei 15,5% (n = 7 von 45) der Fälle auf. Postoperativ reduzierten sich Obstipationsbeschwerden um 28,6% (n = 18 von 63) auf 22,2%. Bei Patienten mit einer präoperativen Inkontinenz wurde eine Verbesserung in 60,7% (n = 17 von 28) der Fälle erreicht, 35,7% (n = 10 von 28) waren vollständig kontinent. Die Steigerung der Kontinenzgrade durch eine abdominale Rektopexie ist statistisch signifikant (Wilcoxon-Test, p = 0,05). Die Einflußgrößen hohes Lebensalter, Prolapsanamnesedauer, Geburtenzahl und präoperative Inkontinenzdauer

Clinical and functional results after abdominal rectopexy: a comparison of dura strips. Vicryl and Dexon gauze as fixation material and suture placement (Ripstein-Corman procedure)

We report our results with abdominal rectopexy (modified Ripstein procedure, Ripstein/Corman) without resection of the colon in 63 patients using lyophylized dura-strips, Vicryl gauze or Dexon gauze, as the underlying fixation material for the mobilized rectum, presacral fascia and fixation suture material. Forty-five of 64 patients (71.4%) were reevaluated by proctoscopic examination and questioning; the mean follow-up time was 52.5 months (range 3–136 months). Postoperative mortality due to the method was 0%; the mortality was 1.6% (n = 1/63) in general for the first postoperative 30-day period as a result of cardiac complications. There were three complications (4.7%) the durating operation. Postoperative morbidity was 25.4% (16/63); infectious complications occurred in 12.7% (8/63) of cases, with one case of spontaneous closure of a pelvicutaneous fistula after intraoperative injury to the rectal wall. Full-thickness rectal prolapse appeared after rectopexy in 4.4% (2/45) (dura material alone) and mucosal prolapse was seen in 15.5% (7/45) of the follow-up group. Constipation was reduced by 28.6% (18/63) to 22.2% during the follow-up. Seventeen of 28 patients (60.7 %) with incontinence showed an improvement; total continence was registered in 35.7% (10/28). The increase in continence as a result of abdominal rectopexy was significant (Wilcoxon, P = 0.05). The special aspects of being in an older age group, having a long history of procidentia, the number of deliveries, the length of the preoperative incontinence period all showed no influence on the postoperative degree of continence (Spearman's rank correlation). In 7/15 cases with persisting incontinence after rectopexy, postanal repair (Parks) was efficient in 7/7 cases leading to total or partial continence. Abdominal rectopexy with the Ripstein-Corman procedure is generally recommended for the treatment of procidentia. Absorbable material for the Ripstein sling is preferred because of the low prolapse recurrency rate and the low infection rate; the absorbability of Vicryl or Dexon gauze might be of advantage in cases of pelvic sepsis after rectopexy, as removal of the gauze is not necessary. Resection of the colon as a treatment for severe constipation is not generally recommended.

     

胆碱能抗炎通路及其在脓毒症治疗中的作用

胆碱能抗炎通路是一种神经-免疫调节通路。迷走神经刺激释放的乙酰胆碱与α7 烟碱型乙酰胆碱受体的 相互作用可阻止促炎细胞因子的合成和释放,最终反馈地调节局部或全身性炎症反应。物理方法刺激迷走神经、药 物(如乙酰胆碱受体激动剂)和超声的应用等均可通过胆碱能抗炎通路有效抑制脓毒症的发展。
