Objective To evaluate the clinical effectiveness of laparoscopic cholecystectomy ( LC) combined with endoscopic sphincter-otomy ( EST) for treatment of gallstones with common bile duct stones. Methods Clinical data of 652 patients who were treated by LCs and ESTs were retrospectively analyzed. Results ESTs were successfully accomplished in 634 patients (97. 2%), and LCs were successfully ac-complished in 621 among the 634 patients (97. 9%) after ESTs. The mean length of hospitalization after LCs was 4 days (2~15 days). In all 652 patients, there were 233 cases of acute pancreatitis, including 171 cases before ESTs and 62 cases (13. 1%) after ESTs, and they were all cured after ESTs. In 621 patients after LCs, bile leakages occurred in 8 patients (1. 2%) and they were cured with intraoperative drainages. Local fluid accumulations occurred in 120 patients (19. 0%), and 118 cases of them healed without management, and the other 2 cases were cured with percutaneous tube-placement drainages guided by ultrasonography because of abscesses. Conclusion It is safe and effective to treat gallstones with common bile duct stones by LC combined with EST because of its high success rate, short hospital stay and mild complications.

Objective:To compare the effect of laparoscopic uterine isthmus cerclage and transvaginal uterine isthmus cerclage in the treatment of cervical incompetence at non pregnant condition.Methods:A total of 63 patients with cervical incompetence from May 2013 to May 2015 in our hospital were enrolled in the retrospective analysis,all the enrolled patients had naturally conceived single birth with complete data after laparoscopic uterine isthmus cerclage or transvaginal uterine isthmus cerclage and were divided into two groups according to two different surgical methods for uterine isthmus cerclage to compare the clinical effect.30 patients treated with laparoscopic uterine isthmus cerclage were,in the research group and the other 33 patients treated with transvaginal uterine isthmus cerclage were in the control group.Results:The treatment success rate of research group (96.67％) was significantly higher than that of the control group(51.52％) (P ＜ 0.05).The research group had got a longer average pregnancy period than control group (P ＜ 0.05).Postoperative abortion rate (3.33％) and preterm birth rate(10.00％) of research group were obviously lower than the control group (48.48％,30.30％)(P＜0.05).The term infant rate of research group (86.67％) was higher than control group (21.21％) (P ＜0.05).The operation time((37.27 ± 1.93 min) and hospital stay(5.17 ±0.38 d) of the research group were less than the control group(P＜0.05).The bleeding amount in surgery of research group(13.13 ±1.57ml) was significantly lower than the control group(31.61 ± 1.87 ml) (P ＜ 0.05).The complication rate of observation group was 0,and the control group was 18.18％.The difference was significant(P ＜ 0.05).Conclusions:Laparoscopic uterine isthmus cerclage in treatment of cervical imcompetence at non pregnant condition has better clinical effect than transvaginal uterine isthmus cerclage.It has higher security and feasibility.It is worth clinically promoting.

To observe the effects of emodin ( Emo) on acute fatty liver in mice induced by DL-ethionine ( DL-Eth) or tetracyclin ( Tetra) and its potential mechanism, ICR mice of acute fatty liver model induced by DL-Eth were orally administered with Emo or positive control, ursodeoxycholic acid ( UDCA) for 7 days. On day 7, except that the control and Emo groups were treated with vehicle control, animals were orally administered with DL-Eth to induce acute fatty liver model. ICR mice of acute fatty liver model induced by Tetra were orally administered with Emo or positive control, Dong Bao Gan Tai ( DB) or total flavonoid C-glycosides from Abrus mollis extract ( AME) for 7 days. From day 4, except that the control group was treated with vehicle control, animals were injec-ted with Tetra intraperitoneally for 4 days to induce acute fatty liver model. Liver histopathological analyses were determined by HE staining. Serum aspartate transaminase ( AST) , alanine transaminase ( ALT) , serum triglyceride ( TG) , hepatic TG and hepatic total cholesteol ( TC) were detected. The expression of phosphorylated AMP-activa-ted kinase ( p-AMPK) , phosphorylated acetyl-CoA carboxylase ( p-ACC) , SREBP1 and fatty acid synthase ( FAS) were determined by Western blot. The expression of fatty acid translocase ( CD36 ) , peroxisome proliferator activa-ted receptor alpha ( PPARα) and microsomal triglyceride transfer protein ( MTTP ) in liver were determined by RT-PCR. Compared with model groups, Emo could improve hepatocyte swelling and hepatic steatosis induced by DL-Eth or Tetra. Serum AST, ALT, serum TG, hepatic TG and hepatic TC were decreased by Emo significantly. DL-Eth-induced increase of fatty acid synthetase-associated protein was down-regulated by Emo. Fatty acid uptake was down-regulated by Emo; fatty acid oxidation and secretion were increased by Emo. Emo might be effective in preventing acute fatty liver in mice induced by DL-Eth or Tetra.

Objective To investigate the effects of 6-minutes of walking exercise (6-MWE) on the exercise tolerance and left ventricular diastolic function (LVDF) of heart failure patients with a normal ejection fraction (HFNEFs).Methods Ninety grade Ⅱ or Ⅲ HFNEFs of the New York heart association (NYHA) were randomly divided into an exercise training group and a control group with 45 cases in each.The control group was treated with routine drugs.The exercise training group was treated with the same drugs plus 6-MWE.Before and after the sixmonth period of treatment,plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were determined,each subject's left atrial volume index (LAVI) was measured with a color ultrasonic cardiogram (UCG),and their 6-minute walk distance (6-MWD) was measured.Results Plasma NT-proBNP levels and 6-MWD improved significantly comparing with before treatment in both groups.The average 6-MWD,LAVI and plasma NT-proBNP level all improved significantly more in the experimental group.Conclusion 6-MWE can significantly improve the exercise tolerance and LVDF of HFNEFs,and improve their quality of life.Walking can be helpful in delaying the development of HFNEF.

Objective To evaluate the localization of mitral valvular(MV)prolapse by transthoracic echocardiography(TTE),transesophageal echocardiography(TEE)and explore the interrelationship between the different subregions of MV prolapse and mitral regurgitation(MR).Methods Total of thirtythree patients with MV prolapse and more than moderate MR were included.TEE was used to further judge the location of scallop lesions and the result of both TTE and TEE were compared with the surgical findings respectively.The relationship between the different subregions of MV prolapse and MR was analyzed.Results Compared with the surgery findings,the accuracy rate of TTE and TEE in diagnosis of MV prolapse was 100％ qualitatively,80％ for TTE and 94％ for TEE in localizing the diseased region with the anterior and posterior MV,the result of TEE was significantly different from TTE(P＜0.05).MR level was related to the location of MV prolapse.Conclusions Compared with the TTE,TEE had more advantages in localizing the position of the MV prolapse.Mitral regurgitation is related to the location of MV prolapse.
