Objective To explore the causes and surgical management of acute gangrenous cholecvstitis(AGC)after endoscopic sphincterotomy(EST).Methods Clinical and pathological data of 1066 patients who underwent EST from June 2003 to January 2007 were analyzed retrospectively.ResultsAGC was complicated in 16 patients(16/1066,1.5%),who underwent emergency operations and no death occurred.During the follow-up period of 4 to 36 months,no infection or obstruction was found.Conclusion Difficuitv in EST manipulation and biliary obstrucion might play a leading role in AGC after EST,and early surgical intervention is effective.

Objective To investigate the diagnostic value of electrophysiological examination for tarsal tunnel syndrome (TTS).Methods Motor nerve conduction velocity (MCV),sensory nerve conduction velocity (SCV),F wave and electromyographic measurements were carried out with 26 clinically suspected TTS patients.Results Of the 26,22 patients were unilaterally affected and 4 were bilaterally affected,so 30 tarsal tunnels in total were affected.All received electrophysiological examination.Of the 30 affected tarsal tunnels,abnormal MCV was detected in 28 of the posterior tibial nerves (93.3％),while abnormal SCV was detected in 27 medial plantar nerves (90％) and 24 lateral plantar nerves (80％).Needle electromyography of 156 targeted foot muscles detected abnormal spontaneous potentials in 90 of them (57.7％),giant potential in 12 muscles (7.7％) and decreased recruitment in 76 (48.7％).Conclusions The distal posterior tibial nerve is impaired in TTS,presenting axonal damage in an electrophysiological examination.Such examinations should have an important role in the diagnosis and differential diagnosis of TTS.

Objective To explore the diagnosis and treatment of gastroparasis syndrome after abdominal operation. Methods Clinical data of 25 cases with gastroparasis syndrome after abdominal operation from Jan 1995 to June 2006 were analysed retrospectively. Results Gastrectomy and nongastrectomy amounted to 16 and 9 cases( portal-azygous vein disconnection in 4 cases, panceaticoduodenectomy in 1 case, partial small intestinectomy and adhesions lysis in 1 case, radical excision of colon carcinoma in 2 cases, choledocholithotomy in 1 case). Gastroparasis syndrome characterized by upper abdominal distension, nausea, vomiting after clipping the pipe or large quantity of gastric drainage after operations. Gastrointestinal series and gastroscopy confirmed functional delayed gastric emptying. All cases recoverd through non-operative therapy including fasting, continuous gastrointestinal decompression, total parenteral nutrition or enteral nutrition, adn administration of gastro-intestinal dynamic medicine. Conclusions Gastroparasis syndrome is the common complication after abdomianl operation, gastrointestinal series, gastroscopy are main diagnostic methods, conservative medication obtains good effect.

Objective To explore the protective effect of Salvia miltiorrhiza on small intestinal ischemia reperfusion injury during intestinal transplantation induced by cytokines in rats.Methods Sixty Sprague Dawley rats were randomly divided into sham operation group,model group and low,mid,high doze treatment group,the superior mesenteric artery was occluded and then released to simulate the model of small intestinal ischemia reperfusion during intestinal transplantation.Tumor necrosis factor-?,interleukin-1?,interleukin-8 both in the plasm and small intestinal tissue were evaluated by ELISA 2 hours after reperfusion,changes of pathology in intestinal mucosa were observed.Results TNF-?,IL-1?,IL-8 were significantly higer(P

Objective To determine the expression spectrum of microRNA(miRNA)in the lung homogenate of rats with chronic obstructive pulmonary disease(COPD)or healthy rats,to look for differentially expressed miRNA, and to explore their potential role in pathogenesis of COPD. Methods Twenty male Sprague-Dawley(SD)rats were randomly divided into normal control group and COPD model group,with 10 rats in each group. COPD rat models were reproduced by smoke inhalation as well as intratracheal instillation of lipopolysaccharide(LPS). The samples of the lung were harvested,and the histopathological examination of the right lung was carried out to evaluate the degree of lung injury. Total RNAs were isolated from the left lung. The miRNA expressions in lung tissue of rats with COPD or normal rats were determined by miRNA chip eichnology to screen the miRNA with differential expression, and hierarchical clustering analysis was made. The data were analyzed to study the expression difference of miRNAs between the two groups,and to construct the miRNA-Target network. Results Compared with normal control group, 20 miRNA with increased expression were found in COPD model group,the top 10 were miR-30c-2,miR-199a-5p, miR-30a, miR-145, miR-151, miR-674-5p, miR-214, miR-423, miR-28 and miR-181b, and only miR-376b-3p showed down-regulation. Hierarchical clustering analysis showed that significant differences in individual miRNA in lung tissue between rats of two groups were found. However,similar samples could not be gathered well,thus it may give rise to inconsistency during the sample preparation. Many miRNAs had multiple target genes in miRNA-Target network, such as miR-30c-2, miR-145, miR-181b, miR-181a, miR-181d, miR-199. Conclusions The study reveals that there is a variance of miRNAs expression profile in lung homogenates between COPD group and the normal control group of rats,and many miRNAs have multiple target genes,such as miR-30c-2,miR-145,miR-181b,miR-181a,miR-181d,and miR-199. Therefore,the results may be valuable to centain extent for the interpretation of COPD pathogenesis.

Objective To explore the clinical value of expression of CEA and CK-20 detected by flow cytometry (FCM) in peritoneal washes on predicting peritoneal metastasis and prognosis of gastric carcinama.Methods Clinicopathological characteristics and follow up data of 105 patients with gastric carcinoma who were underwent D2 radical resection (R0) were collected.Peritoneal washes was collected.Peritoneal lavage cytology examination (PLC) was used to find intraperitoneal free cancer cells (IFCC).FCM was used to determine the CEA and CK-20 expressions.Meanwhile,13 patients with benign lesion on the stomach and the gastric carcinama cell line SGC-7901 were served as the negative and positive control,respectively.Results Positive expression of CEA was in 48 (45.7 ％) patients,of CK-20 was found in 67 (63.8 ％) patients,and of CEA and CK-20 was in 85 (81.0 ％) patients by FCM.However,positive expression of IFCCs was found in 31 patients(29.5 ％) by PLC.The expression of CEA and CK-20 were related to serosa invasion,lymphnode metastasis and pTNM stage (P ＜ 0.05).The median survival of patients with negative expression of both CEA and CK-20 (n =20) was significantly longer those with positive expression (n =30)(52 vs 18 months,P ＜ 0.05).Conclusions Combined Detection of CEA and CK-20 in peritoneal washes by FCM can be used to predict peritoneal micrometastasis and may predict the prognosis of gastric carcinoma.

Objective:To investigate the effects of ultrasound-guided intervention with methotrexate combined with lauromacrogol on uterine wall thickness and menstrual recovery time in patients with uterine scar pregnancy.Methods:Sixty patients with uterine scar pregnancy who received treatment in Jinhua Wenrong Hospital, Jinhua Central Hospital, and Yiwu Maternity and Children Hospital from February 2019 to February 2020 were included in this study. They were randomly assigned to receive either uterine artery embolization treatment ( n = 30, control group) or ultrasound-guided interventions with methotrexate combined with lauromacrogol ( n = 30, study group). The success rate of treatment, uterine wall thickness at the scar, menstrual recovery time, hospitalization time, hospitalization expenses, incidence of adverse reactions, serum levels of beta-human chorionic gonadotropin (β-HCG) and high sensitivity C-reactive protein (hs-CRP) after 7 days of treatment and uterine wall thickness before and after treatment were compared between the study and control groups. Results:After treatment, the success rate of treatment in the study group was significantly higher than that in the control group [96.67% (29/30) vs. 70.00% (21/30), χ 2 = 7.680, P < 0.05]. Before treatment, there were no significant differences in β-HCG and hs-CRP levels between the control and study groups ( t = -0.197, 0.197, both P > 0.05). After treatment, serum level of β-HCG in the control and study groups was significantly decreased ( t = 22.803, 10.233, both P < 0.01), and serum level of hs-CRP in the control and study groups was significantly increased ( t = -16.357, 7.854, both P < 0.001) compared with before treatment. After treatment, there were no significant differences in serum β-HCG and hs-CRP levels between the control and study groups ( t = 20.413, -20.306, both P < 0.05). After treatment, the incidence of adverse reactions in the study group was significantly lower than that in the control group [6.67% (2/30) vs. 30.00% (9/30), χ 2 = 5.455, P < 0.05). After treatment, menstrual recovery time, hospitalization time and hospitalization expenses in the study group were shorter or less than those in the control group ( t = 5.080, 5.398, 7.599, all P < 0.05). There was no significant difference in the thickness of uterine wall at the scar site between the two groups ( t = -1.045, P > 0.05). Conclusion:Ultrasound-guided intervention with methotrexate combined with lauromacrogol for treatment of uterine scar pregnancy can effectively increase the success rate of treatment, promote the restoration of menstruation, shorten the length of hospital stay, and is highly safe.
