Objective To evaluate the efficacy and safety of tiotropium bromide in treating stable mild and moderate chronic obstructive pulmonary diseases. Methods A randomized,double-blind,parallel comparison clinical trial was conducted in 40 patients with COPD. Twenty patients in tiotropium bromide group were treated by tiotropium bromide powder,and another twenty patients in controll group were given ipratropium,in contrast. The spirometry of both groups was conducted. 4 weeks after treatment. Results The forced expiratory volume in one second ( FEV1 ) and forced vital capacity(FVC) in two groups were significantly increased after treatment( P<0.01 ). The increase of FEV1 in tiotropium bromide group was higher than that in controll group after 4-week. There was no significant differ-ence in rescue medication consumptions. The incidence of adverse effects has no statistical difference between two groups. Conclusion Tiotropium bromide is an effective and safe bronchodilator in treating patients with COPD.

Objective To explore the causes and managements of peritoneal laceration in the laparoscopic totally extraperitoneal (TEP) hernia repair during learning curve.Methods The retrospective cross-sectional study was conducted.The clinical data of 120 patients with inguinal hernia who underwent laparoscopic TEP hernia repair in the Third Affiliated Hospital of Anhui Medical University (98 patients) and Anhui Provincial Hospital (22 patients) during surgeons' learning curve between February 2012 and January 2017 were collected.Patients underwent laparoscopic TEP hernia repair,meshes were intraoperatively placed and then fixed by medical glue.Observation indicators:(1) intraoperative situations:surgical procedure,operation time,using of mesh,intraoperative peritoneal laceration;(2) postoperative situations:time to anal exsufflation,time for fluid diet intake,occurrence of complications,duration of hospital stay;(3) follow-up:number of patients receiving follow-up,follow-up time,recurrence of hernia during follow-up,pain in inguinal region,intestinal adhesion and obstruction induced abdominal pain,incisional infection.Follow-up using outpatient examination and telephone interview within 10 days postoperatively and using telephone interview at 10 days postoperatively was performed to detect the recurrence of inguinal hernia,pain in inguinal region,intestinal adhesion and obstruction induced abdominal pain and incisional infection up to May 2017.Measurement data with normal distribution were represented as （x）±s.Results (1) Intraoperative situations:of 120 patients,112 underwent laparoscopic TEP hernia repair,5 converted to laparoscopic transabdominal preperitoneal hernia repair and 3 converted to open surgery due to adhesion between hernial sac and surrounding tissues induced bleeding of separation.Total operation time of 120 patients was (71 ± 13) minutes,including (63± 7) minutes in 106 patients with unilateral hernia and (79 ± 11)minutes in 14 patients with bilateral hernia.All the patients used intraoperatively meshes of 10.0 cm×15.0 cm and 16.0 cm× 10.8 cm.Forty-eight patients had intraoperative peritoneal laceration,peritoneal laceration occurred for reconstruction of preperitoneal space in 10 patients,separation of anterolateral preperitoneal space in 11 patients and improperly operating equipment or hernial sac in 27 patients.Of 48 patients with peritoneal laceration,40 continued to finish operation through acupuncturing into the abdominal cavity for exsufflation and then received peritoneal suture and repair,including 5 with recurrence of indirect inguinal hernia (receiving tissue repair) undergoing peritoneal repair through opening hernial sac,and 8 intraoperatively converted to other or open surgery.(2) Postoperative situations:time to anal exsufflation and time for fluid diet intake in 120 patients were (18± 4) hours and (15±6) hours.Of 120 patients,14 had postoperative complications,scrotal emphysema of 6 patients disappeared in 24 hours anti inguinal and scrotal seroma of 8 patients disappeared after puncture treatment.All the patients were discharged from hospital in 2 days postoperatively.(3) Follow-up:112 of 120 patients were followed up for 3-65 months,with a median time of 31 months.During follow-up,there was no occurrence of recurrence of hernia,pain in inguinal region,intestinal adhesion and obstruction induced abdominal pain and incisional infection.Conclusion During surgeons' learning curve,identifying anatomy of the groin clearly,a right way to treat the hernia sac and broken peritoneum in the operation can ensure the smooth completion of the laparoscopic TEP hernia repair.

AIM To investigate the effects of Tea Po lyp henols on induction of apoptosis in human liver cancer cell etc. Telomerase acti vity of BEL-7404 cells was dramatically declined during the cell incuba tion with Tea Polyphenols. METHODS MTT colorimetric assay and trypan b lue exclusion method were used to examine the growth inhibition ofTea Polyphenols on BEL-7404 cells. Telomerase activity in cell was determined by PCR-ELISA method. Cell morphology and DNA gel electrophoresis were used to observe the apoptosis. RESULTS The solution of Tea Polyphenols showed dose-dependent and time-dependent inh ibitory effects on the proliferation on BEL-7404 cell line. After treatment wit h 0 2 and 0 1 g?L -1 tea polyphenols for 48 hours, cells displayed DNA ladder bands and typical morphological change of apoptosis included: ce ll shrinkage, membrane blebbing, chromatin condensation, nuclear fragmentation etc. Telomerase activit y of BEL-7404 cells was dramatically declined during the cell incubation with Tea Polyphenols. CONCLUSION Tea Polyphenols has growth inhibiti ng effect and may induce apoptosis in BEL-7404 in a certain dose range. The ant icancer mechanism of Tea Polyphenols might be related to the inhibition of telom erase activity.

Type Ⅰ congenital biliary dilatation is a congenital biliary duct defect disease.It is also called congenital choledochocele cyst (CCC).Endoscopic ultrasonography (EUS),magnetic resonance cholangiopacreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) are very important for the diagnosis.Operation is generally regaded as the best choose.It is recommended that cholecystectomy + choledochal cyst excision + hepatic duct jejunum Roux-Y anastomosis is the chief therapeutic method.This article reviews the pathogenesis,classifications,diagnosis and treatment of the disease.
