AIM: To investigate the effect of high dose glargine on the expression profiles of microRNAs in human pancreatic cancer cells.METHODS: Real-time polymerase chain reaction array (RT-PCR) was applied to investigate miRNAs differentially expressed in Sw1990 cells treated with or without 100 IU/L glargine. Stem-loop RT-PCR was used to confirm the results of the array assay in Sw1990 and Panc-1 cells. The effects of miR-95 on cell growth, apoptosis, invasion and migration abilities were respectively examined by CCK8 assay, apoptosis assay, Matrigel invasion and migration assay in Sw1990 and Panc-1 cells. Nude mice xenograft models with Sw1990 cells were built to investigate pancreatic cancer growth in vivo after transfection by the lentivirus pGLV3-GFP- miR-95.RESULTS: Ten miRNAs were significantly up-regulated and 2 miRNAs down-regulated in glargine treated Sw1990 cells when compared with non-treated cells (2.48-fold changes on average, P < 0.01). miR-95, miR-134 and miR-34c-3p are the top three miRNAs regulated by glargine (3.65-fold, 2.67-fold and 2.60-fold changes respectively, P < 0.01) in Sw1990 cells. Stem-loop RT-PCR confirmed that high dose glargine up-regulated the expression of miR-95 and miR-134 in both Sw1990 and Panc-1 cells. The most obvious change is the apparent increase of miR-95. Forced expression of miR-95 significantly increased cell proliferation (Sw1990: 2.510 ± 0.129 vs 2.305 ± 0.187, P < 0.05; Panc-1: 2.439 ± 0.211 vs 2.264 ± 0.117, P < 0.05), invasion (Sw1990: 67.90 ± 12.33 vs 47.30 ± 5.89, P < 0.01; Panc-1: 37.80 ± 8.93 vs 30.20 ± 5.14, P < 0.01), migration (Sw1990: 101 ± 6.00 vs 51.20 ± 8.34, P < 0.01; Panc-1: 91.80 ± 9.22 vs 81.50 ± 7.47, P < 0.01) and inhibited cell apoptosis (Sw1990: 22.05% ± 1.92% vs 40.32% ± 1.93%, P < 0.05; Panc-1: 20.17% ± 0.85% vs 45.60% ± 1.43%, P < 0.05) when compared with paired negative controls, whereas knockdown of miR-95 obtained the opposite effect. Nude mice xenograft models confirmed that miR-95 promoted the growth of pancreatic cancer in vivo when compared with negative control (tumor volume: 373.82 ± 23.67 mL vs 219.69 ± 17.82 mL, P < 0.05).CONCLUSION: These observations suggested that modulation of miRNA expression may be an important mechanism underlying the biological effects of glargine. 相似文献

AIM: To define the benefits of three-dimensional video-assisted thoracoscopic esophagectomy(3D-VATE)over 2D-VATE for esophageal cancer.METHODS: A total of 93 patients with esophageal cancer including 45 patients receiving 3D-VATE and48 receiving 2D-VATE were evaluated. Data related to patient and cancer characteristics, operating time,intraoperative bleeding, morbidity and mortality,postoperative inflammatory markers, Numerical Rating Scale for postoperative pain, Constant-Murley rating system for shoulder recovery and oxygenation index(OI) were collected. All medical records were retrieved from a prospectively maintained oncological database at our institution. A retrospective study was performed to compare the short-term surgical outcomes between the two groups.RESULTS: No significant differences were found between the two groups in either morbidity or mortality(P = 0.328). An enhanced surgical recovery was noted in the 3D group as indicated by shortened thoracoscopic operation time(3D vs 2D: 68 ± 13.79 min vs 83 ± 13min, P 0.01), minor intraoperative blood loss(3D vs 2D: 68.2 ± 10.7 ml vs 89.8 ± 10.4 ml, P 0.01),earlier chest tube removal(3D vs 2D: 2.67 ± 1.01 vs3.75 ± 1.15 d, P 0.01), shorter length of hospital stay(3D vs 2D: 9.07 ± 2.00 vs 10.85 ± 3.40 d, P 0.01), lower in-hospital expenses(3D vs 2D: 74968.4± 9637.8 vs 86211.1 ± 8519.7 RMB, P 0.01), lower pain intensity(P 0.01) and faster recovery of the left shoulder function(P 0.01). Better preservation of the pulmonary function was also found in the 3D group as the decline of the OI post operation was significantly lower than that of the 2D group(P 0.01). Changes of postoperative inflammatory markers, including procalcitonin [postoperative days(PODs) 4 and 7: P 0.01], peripheral granulocytes(PODs 1, 4 and 7: P 0.01) and hypersensitive C-reactive protein(POD 4: P 0.01) in 3D-VATE patients were less than those in the 2D group. Moreover, utilization of the 3D technique extended the dissection of the thoracic lymph nodes(P 0.01), with better exposure of nodes in the left recurrent laryngeal nerve(P = 0.031).CONCLUSION: 3D-VATE could be a more viable technique over 2D-VATE in terms of short-term outcomes for patients with esophageal cancer. 相似文献

AIM: To investigate the effect of polydatin (PD), a resveratrol glucoside, on mast cell degranulation and antiallergic activity. METHODS: After the rats were orally sensitized with ovalbumin (OVA) for 48 d and underwent PD treatment for 4 d, all the rats were stimulated by 100 mg/mL OVA for24 h and then sacrificed for the following experiments. The small intestines from all the groups were prepared for morphology examination by hematoxylin and eosin staining. We also used a smooth muscle organ bath to evaluate the motility of the small intestines. The OVA-specific immunoglobulin E (IgE) production and interleu-kin-4 (IL-4) levels in serum or supernatant of intestinal mucosa homogenates were analyzed by enzyme-linked immunosorbent assay (ELISA). Using toluidine blue stain, the activation and degranulation of isolated rat peritoneal mast cells (RPMCs) were analyzed. Release of histamine from RPMCs was measured by ELISA, and regulation of PD on intracellular Ca 2+ mobilization was investigated by probing intracellular Ca 2+ with fluo-4 fluo-rescent dye, with the signal recorded and analyzed. RESULTS: We found that intragastric treatment with PD significantly reduced loss of mucosal barrier integrity in the small intestine. However, OVA-sensitization caused significant hyperactivity in the small intestine of allergic rats, which was attenuated by PD administration by 42% (1.26 ± 0.13 g vs OVA 2.18 ± 0.21 g, P < 0.01). PD therapy also inhibited IgE production (3.95 ± 0.53 ng/mL vs OVA 4.53 ± 0.52 ng/mL, P < 0.05) by suppressing the secretion of Th2-type cytokine, IL-4, by 34% (38.58 ± 4.41 pg/mLvs OVA 58.15 ± 6.24 pg/mL, P < 0.01). The ratio of degranulated mast cells, as indicated by vehicles (at least five) around the cells, dramatically increased in the OVA group by 5.5 fold (63.50% ± 15.51% vs phosphate-buffered saline 11.15% ± 8.26%, P < 0.001) and fell by 65% after PD treatment (21.95% ± 4.37% vs OVA 63.50% ± 15.51%, P < 0.001). PD mediated attenuation of mast cell degranulation was fur 相似文献

AIM:To determine whether the application of postoperative intravenous(IV)-iron for acute isovolemic anemia after gastrectomy for cancer may be effective.METHODS:Among 2078 gastric cancer patients who underwent surgery between February 2007 and August2009 at the National Cancer Center Korea,368 patients developed post-operative anemia[hemoglobin-(Hb)-level<9 g/dL]within the first postoperative week.Patients requiring transfusions were excluded.IV-iron was administered to 63 patients(iron group).Sixty patients were observed without treatment(observation group).The clinical outcomes of the groups were compared concerning clinicopathologic data,morbidity,and changes in Hb levels using Fisher’s exact test,Student’s t-test and the Z-test.RESULTS:The initial Hb level was higher in the iron group than in the observation group(7.3±1.0 g/dL vs8.4±0.5 g/dL,P<0.001).The slope of the changes in the Hb level was significantly higher in the iron group than in the observation group(0.648±0.054 vs 0.349±0.038,P<0.001).The Hb level 1 and 3 mo postoperatively increased from 10.7±1.3 to 11.9±1.3g/dL in the iron group(P=0.033)and from 10.1±1.0to 10.8±1.4 g/dL in the observation group(P<0.001).The postoperative hospital stay was significantly longer in the iron group than in the observation group(10.5±6.8 d vs 7.6±5.5 d,P=0.011).There were no significant differences in the major and surgical complications between the groups(6.3%vs 13.3%,P=0.192;9.5%vs 3.3%,P=0.164).CONCLUSION:IV-iron supplementation may be an effective treatment for post-operative isovolemic postgastrectomy anemia and may be a better alternative than observation. 相似文献

AIM: To prospectively evaluate the effectiveness and safety of continuous wound infiltration(CWI) for pain management after open gastrectomy. METHODS: Seventy-five adult patients with American Society of Anesthesiologists(ASA) Physical Status Classification System(ASA) grade 1-3 undergoing open gastrectomy were randomized to three groups. Group 1 patients received CWI with 0.3% ropivacaine(group CWI). Group 2 patients received 0.5 mg/m L morphine intravenously by a patient-controlled analgesia pump(PCIA)(group PCIA). Group 3 patients received epidural analgesia(EA) with 0.12% ropivacaine and 20 μg/m L morphine with an infusion at 6-8 m L/h for 48 h(group EA). A standard general anesthetic technique was used for all three groups. Rescue analgesia(2 mg bolus of morphine, intravenous) was given when the visual analogue scale(VAS) score was ≥ 4. The outcomes measured over 48 h after the operation were VAS scores both at rest and during mobilization, total morphine consumption, relative side effects, and basic vital signs. Further results including time to extubation, recovery of bowel function, surgical wound healing,mean length of hospitalization after surgery, and the patient's satisfaction were also recorded.RESULTS: All three groups had similar VAS scores during the first 48 h after surgery. Group CWI and group EA, compared with group PCIA, had lower morphine consumption(P 0.001), less postoperative nausea and vomiting(1.20 ± 0.41 vs 1.96 ± 0.67, 1.32 ± 0.56 vs 1.96 ± 0.67, respectively, P 0.001), earlier extubation(16.56 ± 5.24 min vs 19.76 ± 5.75 min, P 0.05, 15.48 ± 4.59 min vs 19.76 ± 5.75 min, P 0.01), and earlier recovery of bowel function(2.96 ± 1.17 d vs 3.60 ± 1.04 d, 2.80 ± 1.38 d vs 3.60 ± 1.04 d, respectively, P 0.05). The mean length of hospitalization after surgery was reduced in groups CWI(8.20 ± 2.58 d vs 10.08 ± 3.15 d, P 0.05) and EA(7.96 ± 2.30 d vs 10.08 ± 3.15 d, P 0.01) compared with group PCIA. All three groups had similar patient satisfaction and wound healing, but group PCIA was prone to higher sedation scores when compared with groups CWI and EA, especially during the first 12 h after surgery. Group EA had a lower mean arterial pressure within the first postoperative 12 h compared with the other two groups.CONCLUSION : CWI with ropivacaine yields a satisfactory analgesic effect within the first 48 h after open gastrectomy, with lower morphine consumption and accelerated recovery. 相似文献

AIM:To compare the clinical outcome of single-incision laparoscopic cholecystectomy(SILC)and three-incision laparoscopic cholecystectomy(3ILC)for acute cholecystitis.METHODS:From July 2009 to September 2012,136patients underwent SILC or 3ILC for acute cholecystitis at a tertiary referral hospital.One experienced surgeon performed every procedure using 5 or 10 mm 30-degree laparoscopes,straight instruments,and conventional ports.Five patients with perforated gallbladder and diffuse peritonitis and 23 patients with mild acute cholecystitis were excluded.The remaining 108 patients were divided into complicated and uncomplicated groups according to pathologic findings.Patient demography,clinical data,operative results and complications were recorded and analyzed.RESULTS:Fifty patients with gangrenous cholecystitis,gallbladder empyema,or hydrops were classified as the complicated group,and 58 patients with acute cholecystitis were classified as the uncomplicated group.Twenty-three(46.0%)of the patients in the complicated group(n=50)and 39(67.2%)of the patients in the uncomplicated group(n=58)underwent SILC;all others underwent 3ILC.The postoperative length of hospital stay(PLOS)was significantly shorter in the SILC subgroups than the 3ILC subgroups(3.5±1.1 d vs 4.6±1.3 d,P<0.01 in the complicated group;2.9±1.1 d vs 3.7±1.4 d,P<0.05 in the uncomplicated group).The maximum body temperature recorded at day 1 and at day 2 following the procedure was lower in the SILC subgroups,but the difference reached statistical significance only in the uncomplicated group(37.41±0.56℃vs 37.80±0.72℃,P<0.05 on postoperative day 1;37.10±0.43℃vs 37.57±0.54℃,P<0.01 on postoperative day 2).The operative time,estimated blood loss,postoperative narcotic use,total length of hospital stay,conversion rates,and complication rates were similar in both SILC and 3ILC subgroups.The complicated group had longer operative time(122.2±35.0 min vs 106.6±43.6 min,P<0.05),longer PLOS(4.1±1.3 d vs 3.2±1.2 d,P<0.001),and 相似文献

AIM: To compare shortand long-term outcomes of laparoscopy-assisted and open distal gastrectomy for gastric cancer. METHODS: A retrospective study was performed by comparing the outcomes of 54 patients who underwent laparoscopy-assisted distal gastrectomy (LADG) with those of 54 patients who underwent open distal gastrectomy (ODG) between October 2004 and October 2007. The patients’ demographic data (age and gender), date of surgery, extent of lymphadenectomy, and differentiation and tumor-node-metastasis stage of the tumor were examined. The operative time, intraoperative blood loss, postoperative recovery, complications, pathological findings, and follow-up data were compared between the two groups.RESULTS: The mean operative time was significantly longer in the LADG group than in the ODG group (259.3 ± 46.2 min vs 199.8 ± 40.85 min; P < 0.05), whereas intraoperative blood loss and postoperative complications were significantly lower (160.2 ± 85.9 mL vs 257.8 ± 151.0 mL; 13.0% vs 24.1%, respectively, P < 0.05). In addition, the time to first flatus, time to initiate oral intake, and postoperative hospital stay were significantly shorter in the LADG group than in the ODG group (3.9 ± 1.4 d vs 4.4 ± 1.5 d; 4.6 ± 1.2 d vs 5.6 ± 2.1 d; and 9.5 ± 2.7 d vs 11.1 ± 4.1 d, respectively; P < 0.05). There was no significant difference between the LADG group and ODG group with regard to the number of harvested lymph nodes. The median followup was 60 mo (range, 5-97 mo). The 1-, 3-, and 5-year disease-free survival rates were 94.3%, 90.2%, and 76.7%, respectively, in the LADG group and 89.5%, 84.7%, and 82.3%, respectively, in the ODG group. The 1-, 3-, and 5-year overall survival rates were 98.0%, 91.9%, and 81.1%, respectively, in the LADG group and 91.5%, 86.9%, and 82.1%, respectively, in the ODG group. There was no significant difference between the two groups with regard to the survival rate. CONCLUSION: LADG is suitable and minimally invasive for treating distal gastric cancer and can achieve si 相似文献

AIM:To evaluate the use of the Roux loop on the postoperative course in patients submitted for gastroenteroanastomosis(GE).METHODS:Non-jaundiced patients(n=41)operated on in the Department of General and Transplant Surgery in Lodz,between January 2010 and December 2011 were enrolled.The tumor was considered unresectable when liver metastases or major vascular involvement were confirmed.Patients were randomized to receive Roux(n=21)or conventional GE(n=20)on a prophylactic basis.RESULTS:The mean time to nasogastric tube withdrawal in Roux GE group was shorter(1.4±0.75 vs2.8±1.1,P<0.001).Time to starting oral liquids,soft diet and regular diet were decreased(2.3±0.86 vs 3.45±1.19;P<0.001;3.3±0.73 vs 4.4±1.23,P<0.001and 4.5±0.76 vs 5.6±1.42,P=0.002;respectively).The Roux GE group had a lower use of prokinetics(10mg thrice daily for 2.2±1.8 d vs 3.7±2.6 d,P=0.044;total 62±49 mg vs 111±79 mg,P=0.025).The mean hospitalization time following Roux GE was shorter(7.7 d vs 9.6 d,P=0.006).Delayed gastric emptying(DGE)was confirmed in 20%after conventional GE but in none of the patients following Roux GE.CONCLUSION:Roux gastrojejunostomy during open abdomen exploration in patients with unresectable pancreatic cancer is easy to perform,decreases the incidence of DGE and lowers hospitalization time. 相似文献

AIM:To evaluate the feasibility,safety,and oncologic outcomes of laparoscopic extended right hemicolectomy(LERH)for colon cancer.METHODS:Since its establishment in 2009,the Southern Chinese Laparoscopic Colorectal Surgical Study(SCLCSS)group has been dedicated to promoting patients’quality of life through minimally invasive surgery.The multicenter database was launched by combining existing datasets from members of the SCLCSS group.The study enrolled 220 consecutive patients who were recorded in the multicenter retrospective database and underwent either LERH(n=119)or open extended right hemicolectomy(OERH)(n=101)for colon cancer.Clinical characteristics,surgical outcomes,and oncologic outcomes were compared between the two groups.RESULTS:There were no significant differences in terms of age,gender,body mass index(BMI),history of previous abdominal surgery,tumor location,and tumor stage between the two groups.The blood loss was lower in the LERH group than in the OERH group[100(100-200)mL vs 150(100-200)mL,P<0.0001].The LERH group was associated with earlier first flatus(2.7±1.0 d vs 3.2±0.9 d,P<0.0001)and resumption of liquid diet(3.6±1.0 d vs 4.2±1.0 d,P<0.0001)compared to the OERH group.The postoperative hospital stay was significantly shorter in the LERH group(11.4±4.7 d vs 12.8±5.6 d,P=0.009)than in the OERH group.The complication rate was 11.8%and17.6%in the LERH and OERH groups,respectively(P=0.215).Both 3-year overall survival[LERH(92.0%)vs OERH(84.4%),P=0.209]and 3-year disease-free survival[LERH(84.6%)vs OERH(76.6%),P=0.191]were comparable between the two groups.CONCLUSION:LERH with D3 lymphadenectomy for colon cancer is a technically feasible and safe procedure,yielding comparable short-term oncologic outcomes to those of open surgery. 相似文献

AIM: To identify the radiological characteristics of focal autoimmune pancreatitis (f-AIP) useful for differentiation from pancreatic cancer (PC). METHODS: Magnetic resonance imaging (MRI) and triple-phase computed tomography (CT) scans of 79 patients (19 with f-AIP, 30 with PC, and 30 with a normal pancreas) were evaluated retrospectively. A radiologist measured the CT attenuation of the pancreatic parenchyma, the f-AIP and PC lesions in triple phases. The mean CT attenuation values of the f-AIP lesions were compared with those of PC, and the mean CT attenuation values of pancreatic parenchyma in the three groups were compared. The diagnostic performance of CT attenuation changes from arterial phase to hepatic phase in the differentiation between f-AIP and PC was evaluated using receiver operating characteristic (ROC) curve analysis. We also investigated the incidence of previously reported radiological findings for differentiation between f-AIP and PC. RESULTS: The mean CT attenuation values of f-AIP lesions in enhanced phases were significantly higher than those of PC (arterial phase: 60 ± 7 vs 48 ± 10, P < 0.05; pancreatic phase: 85 ± 6 vs 63 ± 15, P < 0.05; hepatic phase: 95 ± 7 vs 63 ± 13, P < 0.05). The mean CT attenuation values of f-AIP lesions were significantly lower those of uninvolved pancreas and normal pancreas in the arterial and pancreatic phase of CT (P < 0.001, P < 0.001), with no significant difference at the hepatic phase or unenhanced scanning (P = 0.4, P = 0.1). When the attenuation value increase was equal or more than 28 HU this was considered diagnostic for f-AIP, and a sensitivity of 87.5%, specificity of 100% and an area under the ROC curve of 0.974 (95%CI: 0.928-1.021) were achieved. Five findings were more frequently observed in f-AIP patients: (1) sausageshaped enlargement; (2) delayed homogeneous enhancement; (3) hypoattenuating capsule-like rim; (4) irregular narrowing of the main pancreatic duct (MPD) and/or stricture of the common bile duct (CBD); and (5) M 相似文献

AIM:To compare laparoscopic pancreaticoduodenectomy(TLPD) during the initial learning curve with open pancreaticoduodenectomy in terms of outcome and costs.METHODS:This is a retrospective review of the consecutive patients who underwent TLPD between December 2009 and April 2014 at our institution.The experiences of the initial 15 consecutive TLPD cases,considered as the initial learning curve of each surgeon,were compared with the same number of consecutive laparotomy cases with the same spectrum of diseases in terms of outcome and costs.Laparoscopic patients with conversion to open surgery were excluded.Preoperative demographic and comorbidity data were obtained.Postoperative data on intestinal movement,pain score,mortality,complications,and costs were obtained for analysis.Complications related to surgery included pneumonia, intra-abdominal abscess,postpancreatectomy hemorrhage,biliary leak,pancreatic fistula,delayed gastric emptying,and multiple organ dysfunction syndrome.The total costs consisted of cost of surgery,anesthesia,and admission examination.RESULTS:A total of 60 patients,including 30 consecutive laparoscopic cases and 30 consecutive open cases,were enrolled for review.Demographic and comorbidity characteristics of the two groups were similar.TLPD required a significantly longer operative time(513.17 ± 56.13 min vs 371.67 ± 85.53 min,P 0.001).The TLPD group had significantly fewer mean numbers of days until bowel sounds returned(2.03 ± 0.55 d vs 3.83 ± 0.59 d,P 0.001) and exhaustion(4.17 ± 0.75 d vs 5.37 ± 0.81 d,P 0.001).The mean visual analogue score on postoperative day 4 was less in the TLPD group(3.5 ± 9.7 vs 4.47 ± 1.11,P 0.05).No differences in surgery-related morbidities and mortality were observed between the two groups.Patients in the TLPD group recovered more quickly and required a shorter hospital stay after surgery(9.97 ± 3.74 d vs 11.87 ± 4.72 d,P 0.05).A significant difference in the total cost was found between the two groups(TLPD 81317.43 ± 2027.60 RMB vs laparotomy 78433.23 ± 5788.12 RMB,P 0.05).TLPD had a statistically higher cost for both surgery(24732.13 ± 929.28 RMB vs 19317.53 ± 795.94 RMB,P 0.001)and anesthesia(6192.37 ± 272.77 RMB vs 5184.10 ± 146.93 RMB,P 0.001),but a reduced cost for admission examination(50392.93 ± 1761.22 RMB vs 53931.60 ± 5556.94 RMB,P 0.05).CONCLUSION:TLPD is safe when performed by experienced pancreatobiliary surgeons during the initial learning curve,but has a higher cost than open pancreaticoduodenectomy. 相似文献

AIM:To investigate whether therapeutic treatment with melatonin could protect rats against acute pancreatitis and its associated lung injury.METHODS:Seventy-two male Sprague-Dawley rats were randomly divided into three groups:the sham operation(SO),severe acute pancreatitis(SAP),and melatonin treatment(MT) groups.Acute pancreatitis was induced by infusion of 1 mL/kg of sodium taurocholate(4% solution) into the biliopancreatic duct.Melatonin(50 mg/kg) was administered 30 min before pancreatitis was induced,and the severity of pancreatic and pulmonary injuries was evaluated 1,4 and 8 h after induction.Serum samples were collected to measure amylase activities,and lung tissues were removed to measure levels of mRNAs encoding interleukin 22(IL-22) and T helper cell 22(Th22),as well as levels of IL-22.RESULTS:At each time point,levels of mRNAs encoding IL-22 and Th22 were significantly higher(P 0.001) in the MT group than in the SAP group(0.526 ± 0.143 vs 0.156 ± 0.027,respectively,here and throughout,after 1 h;0.489 ± 0.150 vs 0.113 ± 0.014 after 4 h;0.524 ± 0.168 vs 0.069 ± 0.013 after 8 h,0.378 ± 0.134 vs 0.122 ± 0.015 after 1 h;0.205 ± 0.041 vs 0.076 ± 0.019 after 4 h;0.302 ± 0.108 vs 0.045 ± 0.013 after 8 h,respectively) and significantly lower(P 0.001) in the SAP group than in the SO group(0.156 ± 0.027 vs 1.000 ± 0.010 after 1 h;0.113 ± 0.014 vs 1.041 ± 0.235 after 4 h;0.069 ± 0.013 vs 1.110 ± 0.213 after 8 h,0.122 ± 0.015 vs 1.000 ± 0.188 after 1 h;0.076 ± 0.019 vs 0.899 ± 0.125 after 4 h;0.045 ± 0.013 vs 0.991 ± 0.222 after 8 h,respectively).The mean pathological scores for pancreatic tissues in the MT group were significantly higher(P 0.01) than those for samples in the SO group(1.088 ± 0.187 vs 0.488 ± 0.183 after 1 h;2.450 ± 0.212 vs 0.469 ± 0.242 after 4 h;4.994 ± 0.184 vs 0.513 ± 0.210 after 8 h),but were significantly lower(P 0.01) than those for samples in the SAP group at each time point(1.088 ± 0.187 vs 1.969 ± 0.290 after 1 h;2.450 ± 0.212 vs 3.344 ± 0.386 after 4 h;4.994 ± 0.184 vs 6.981 ± 0.301 after 8 h).The severity of SAP increased significantly(P 0.01) over time in the SAP group(1.088 ± 0.187 vs 2.450 ± 0.212 between 1 h and 4 h after inducing pancreatitis;and 2.450 ± 0.212 vs 4.994 ± 0.184 between 4 and 8 h after inducing pancreatitis).CONCLUSION:Melatonin protects rats against acute pancreatitis-associated lung injury,probably through the upregulation of IL-22 and Th22,which increases the innate immunity of tissue cells and enhances their regeneration. 相似文献

AIM: To assess the impact of fast-track surgery (FTS) on hospital stay, cost of hospitalization and complications after radical total gastrectomy. METHODS: A randomized, controlled clinical trial was conducted from November 2011 to August 2012 in the Department of Digestive Surgery, Xijing Hospital of Digestive Diseases, the Fourth Military Medical University. A total of 122 gastric cancer patients who met the selection criteria were randomized into FTS and conventional care groups on the first day of hospitalization. All patients received elective standard D2 total gastrectomy. Clinical outcomes, including duration of flatus and defecation, white blood cell count, postoperative pain, duration of postoperative stay, cost of hospitalization and complications were recorded and evaluated.Two specially trained doctors who were blinded to the treatment were in charge of evaluating postoperative outcomes, discharge and follow-up. RESULTS: A total of 119 patients finished the study, including 60 patients in the conventional care group and 59 patients in the FTS group. Two patients were excluded from the FTS group due to withdrawal of consent. One patient was excluded from the conventional care group because of a non-resectable tumor. Compared with the conventional group, FTS shortened the duration of flatus (79.03 ± 20.26 hvs 60.97 ± 24.40 h, P = 0.000) and duration of defecation (93.03 ± 27.95 h vs 68.00 ± 25.42 h, P = 0.000), accelerated the decrease in white blood cell count [P < 0.05 on postoperative day (POD) 3 and 4], alleviated pain in patients after surgery (P < 0.05 on POD 1, 2 and 3), reduced complications (P < 0.05), shortened the duration of postoperative stay (7.10 ± 2.13 dvs 5.68 ± 1.22 d,P = 0.000), reduced the cost of hospitalization (43783.25 ± 8102.36 RMBvs 39597.62 ± 7529.98 RMB,P = 0.005), and promoted recovery of patients. CONCLUSION: FTS could be safely applied in radical total gastrectomy to accelerate clinical recovery of gastric cancer patients. 相似文献

AIM:To investigate whether computed tomography with 3D imaging(3DCT)can reduce the risks associated with laparoscopic surgery.METHODS:We performed a retrospective case-control study evaluating the efficacy of preoperative 3DCT of the splenic vascular anatomy on surgical outcomes in patients undergoing laparoscopic spleen-preserving splenic hilar lymph node(LN)dissection for upper-or middle-third gastric cancer.The clinical records of 312patients with upper-or middle-third gastric cancer who underwent laparoscopic total gastrectomy with spleenpreserving splenic lymph node dissection in our hospital from January 2010 to June 2013 were collected,and the patients were divided into two groups(group 3DCT vs group NO-3DCT)depending on whether they underwent 3DCT or not.Clinicopathologic characteristics,operative and postoperative measures,the number of retrieved LNs,and complications were compared between these two groups.Patients were further compared regarding operative and postoperative measures,the number of retrieved LNs,and complications when subdivided by body mass index(≥23 and<23 kg/m2)and the number of operations performed by their surgeon(≤40 vs>40).RESULTS:The mean numbers of retrieved splenic hilar LNs were similar in patients in group 3DCT and group NO-3DCT(2.85±2.33 vs 2.48±2.18,P>0.05).The operation time and blood loss at the splenic hilum were lower in the patients in group 3DCT(P<0.05 each).The postoperative recovery time and complication rates were similar between the two groups(P>0.05 each).Subgroup analysis showed that the operation time at the splenic hilum in patients with a BMI≥23 kg/m2was significantly shorter in patients in group 3DCT than in group NO-3DCT(20.27±5.84 min vs 26.17±11.01 min,P=0.003).In patients with a BMI<23kg/m2,the overall operation time(171.8±26.32 min vs 188.09±52.63 min,P=0.028),operation time at the splenic hilum(19.39±5.46 min vs 23.74±9.56min,P=0.001),and blood loss at the splenic hilum(13.27±4.96 mL vs 17.98±8.12 mL,P=0.000)were significantly lower in patients in group 3DCT than in group NO-3DCT.After 40 operations,the operation time(18.63±4.40 min vs 23.85±7.92 min,P=0.000)and blood loss(13.10±4.17 mL vs 15.10±4.42 mL,P=0.005)at the splenic hilum were significantly lower in patients who underwent 3DCT,but there were no significant between-group differences prior to 40 operations.CONCLUSION:3DCT is critical for surgical guidance to reduce the risks of splenic LN dissection.This method may be important in safely facilitating laparoscopic spleen-preserving splenic LN dissection. 相似文献

AIM: To investigate celiac artery variations in gastric cancer patients and the impact on gastric cancer surgery,and also to discuss the value of the ultrasonic knife in reducing the risk caused by celiac artery variations.METHODS: A retrospective analysis was conducted to investigate the difference in average operation time,intraoperative blood loss, number of harvested lymph nodes, average postoperative drainage within 3 d,and postoperative hospital stay between the group with vascular variations and no vascular variations,and between the ultrasonic harmonic scalpel and conventional electric scalpel surgery group.RESULTS: One hundred and fifty-eight cases presented with normal celiac artery, and 80 presented with celiac artery variation(33.61%). The average operation time,blood loss, average drainage within 3 d after surgery in the celiac artery variation group were significantly more than in the no celiac artery variation group(215.7 ± 32.7 min vs 204.2 ± 31.3 min, 220.0 ± 56.7mL vs 163.1 ± 52.3 mL, 193.6 ± 41.4 mL vs 175.3± 34.1 mL, respectively, P 0.05). In celiac artery variation patients, the average operation time, blood loss, average drainage within 3 d after surgery in the ultrasonic harmonic scalpel group were significantly lower than in the conventional electric scalpel surgery group(209.5 ± 34.9 min vs 226.9 ± 29.4 min, 207.5 ±57.1 mL vs 235.6 ± 52.9 mL, 184.4 ± 38.2 mL vs 205.0± 42.9 mL, respectively, P 0.05), and the number of lymph node dissections was significantly higher than in the conventional surgery group(25.5 ± 9.2 vs 19.9 ±7.8, P 0.05).CONCLUSION: Celiac artery variation increases thedifficulty and risk of radical gastrectomy. Preoperative imaging evaluation and the application of ultrasonic harmonic scalpel are conducive to radical gastrectomy. 相似文献
