Objective To investigate the feasibility and significance of laparoscopic choledocholithotomy with T-tube drainage. Methods A total of 60 cases of common bile duct stones complicated with gallbladder stones were treated with laparoscopic cholecystectomy and common bile duct exploration with T-tube drainage. Results The operation was performed successfully in all the cases,without conversions to open surgery.Bile leakage occurred in 2 cases and was cured with conservative treatment.Residual stones were found in 6 cases and a postoperative choledochoscopy was required.The operative time was 90~180 min(mean,110 min),the blood loss was 10~50 ml(mean,20 ml).Follow-up checkups in 53 cases(88.3%) for 2~33 months(mean,13.2 months) revealed no abdominal pain,fever,or jaundice.Conclusions Laparoscopic cholecystectomy and common bile duct exploration for the treatment of common bile duct stones complicated with gallbladder stones is feasible and minimally invasive.

BACKGROUND:Combination of biological and optical technique is used to study the molecular mechanism of cell proliferation and apoptosis, which has become the study hotspot in the filed of bioengineering.OBJECTIVE: The goal of this study was to study the molecular mechanism of XAP-induced apoptosis in single living human lung adenocarcinoma (ASTC-a-1) cells by using confocal fluorescence microscopy imaging and fluorescence resonance energy transfer (FRET) techniques.DESIGN: A controlled observation.SETTING: Institute of Laser Life Science (Key Laboratory of Education Department), South China Normal University.MARERIALS: This experiment was carried out in the Institute of Laser Life Science (Key Laboratory of Education Ministry), South China Normal University between October 2006 and March 2007. Human lung adenocarcinoma (ASTC-a-1) cells were cultured in our laboratory. Xiaoaiping (XAP) parenteral solution was purchased from Tonghua Shenyuan Pharmaceutical Co.,Ltd (No. Z20025869), and G418 was purchased from Huamei Biological Company. SCAT3 was provided by Professor Masayuki Miura. Auto microplate reader (infinite M200, Tecan,Austria)and mitochondrial location fluorescent probe (Mitertracker Red)was purchased from Molecular Probe Company.METHODS: ① The inhibition of XAP at different doses to ASTC-a-1 cell viability was detected by CCK-8. ② Dynamical change of caspase 3-induced by XAP was detected by confocal fluorescence microscopy imaging and fluorescence resonance energy transfer (FRET) techniques. ③The fluorescence emission spectrum of SCAT3 was detected by confocal fluorescence microscopy imaging at different time points after XAP treatment.MAIN OUTCOME MEASURES: ①Cell viability after XAP treatment. ② Dynamic change of fluorescence resonance energy transfer efficiency of SCAT3 detected after XAP treatment. ③ Dynamical change of mitochondrial morphology after XAP treatment.RESULTS: ①XAP inhibited the viability of tumor cells dose-dependently. ② XAP induced the activation of intracellular caspase 3. ③Some mitochondria became dot, and some were cracked after XAP treatment.CONCLUSION: XAP can induce the apoptosis of ASTC-a-1, and caspase 3 is involved in the regulation course.

Objective To investigate the preventive and therapeutic effects of Shenlixin Granules on chronic renal failure rats.Methods The chronic renal failure rat models were caused by adenine.After the treatment of Shenlixin Granules,the body weight,urine volume and renal index of models were examined.Results Shenlixin Granules could obviously inhibit the decrease of body weight and urine volume,reduce the renal index and had obvious protective effect on the renal tissue.Conclusions Shenlixin Granules has a preventive and therapeutic effect on chronic renal failure.

ObjectiveTo evaluate treatment of type 2 diabetes mellitus (T2DM) by laparoscopic Roux-en-Y gastric bypass (LRYGB) using different amastomoses. MethodsTwenty one T2DM patients were divided into two groups:transoral EEA (OrVil) and Endo-GIA according to ways of gastrointestinal anatomosis andunderwentLRYGB. Clinicaldataincluding outcomeof operation, complications,preoperative and postoperative oral glucose tolerance test (OGTT),Homa-IR,Homa-β,blood lipid and nutrition status were analyzed.ResultsLRYGB procedures were successfully performed in all the 21 patients with no conversion to open surgery.The difference of intraoperative blood loss,postoperative recovery time between two groups was not significant.The mean operation time in OrVil group ( 126 ± 29 )mins was shorter than that in Endo-GIA group ( 156 ± 28 ) mins ( P ＜ 0.05 ),but at the same time,the mean expenditure was higher. Evaluated on three months after operation,the T2DM cure rate was 78％,and effective rate was 100％ in OrVil goup and those were 83％,100％ respectively in Endo-GIA group.No postoperative malnutrition, anemia or severe complication occurred.ConclusionsThe efficiency of laparoscopic Roux-en-Y gastric bypass using different amastomoses was same in the treatment of type 2 diabetes mellitus.The operation time was shorter in OrVil group but the expenditure was higher.

Objective To evaluate some key steps influencing success rate in process of totally laparoscopic extraperitoneal herniorrhaphy(TEPH). Methods Between October 2006 and May 2009,we performed totally laparoscopic extraperitoneal herniorrhaphy in 98 patients with like procedures and under the same condition. Results The critical procedures of the operation are related to the establishment of the extraperitoneal cleavage. We used one-way anova analysis. The operation time in different peritoneal burst sites have no significant difference (P > 0. 05), but the operation time in different burst periods have significant difference(P <0. 05). The timing at which the burst occurs significantly influence the length of operation, while the rapture sites don't influence the operation time. The conversion rate was higher and operation time was longer between the cases with the rapture occurrence in early period and in mid and late period. Postoperatively 98 patients were followed up. The follow-up rate was 100%. The median follow-up time was 18 months. Three patients complained local discomfort one month after operation, which subsided after 2 months. There was no recurrence or chronic pain case. Conclusion The burst of the peritoneum during the process of establishing extraperitoneal cleavage significantly influences the success rate of TEPH.

Objective To study and summarize the successful experience and the safety, easibility, practicality and operation skills of totally laparoscopic extraperitoneal herniorrhaphy (TEP). Methods From October 2006 to May 2008,225 patients in our two hospitals were performed TEP (265 totally laparoscopic extraperitoneal hernia repairs for inguinal hernia), including 55 direct inguinal hernia, 197 indirect inguinal hernia and 13 complex inguinal hernia operations. Among the 225 patients, 185 patients had unilateral hernia and 40 patients had bilateral hernias, including 29 recurrent hernia. Results The operations were lasted for 30 to 182 minutes(the average operating duration was 48 minutes for unilateral hernia and 106 minutes for bilateral hernia). The patients stayed in hospital for 2 to 8 days(the average inpatient hospital stay was 3.0 ± 1.2 days). The most common complication was scrotum bematomas,which appeared in 18 cases. Urinary re-tention appeared in 21 cases. Inguinal pain appeared in 5 cases. Bladder injury appeared 1 case. All the pa-tients were followed up for 3 months- 3 years. There was only 1 case of recurrence. Conclusions The proce-dure of TEP is safe,with faster postoperative recover,less pain,lower incidence of pain,better comfort quality and lower recurrence rate. TEP should be the main laparoscopic procedure for inguinal hernia repair.

Objective To discuss the operative difficulties and management in laparoscopic thyroidectomy.Method The clinical data of 169 cases undergoing laparoscopic thyroidectomy were retrospectively analyzed.Result Among 169 cases,only 2 cases were switched to open surgery.Among the other 167 cases local thyroidectomy for thyroid adenoma Was performed in 37 cases,one side subtotal thyroidectomy in 63 cases,two side subtotal thyroidectomy in 42 cases,laparoscopic subtotal thyroideetomy was done in 20 cases for Grave's disease,and radical thyroidectomy was undeRaken in 5 cases of thyroid carcinoma.Postoperatively fat colliquation occurred in 2 cases,pneumohypoderma,skin bruise and temporary vocal dullness or hoarsness in 1 each case.There was no postoperative recurrent laryngeal nerve injury,nor that of the parathyroid gland. Conclusions Laparoscopie thyroidectomy has its own intraoperative difficulties. Accurate operative skills and careful perioperative management can decrease the occurrence of complications.
