Objective To compare the successful ratio, efficacy and complications between ultrasound-guided and X-ray-guided endoscopic biliary drainage (EBD). Methods EBD was performed in 62 patients under ultrasound guidance and 54 patients under X-ray guidance. Serum bilirubin, the bile duct diameter and the changes of clinical symptoms were compared before and after the procedure. Results Tube placement was successfully achieved in 54 of 62 patients under ultrasound guidance and 51 of 54 patients under X-ray guidance. The serum direct bilirubin and the common bile duct diameter in patients with ultrasound guidance before and one week after procedure were (205.41±115.27) μmol/L vs. (106.47±82.16) μmol/L and (12.6±7.1) mm vs. (8.5±3.1) mm, respectively, with significant difference (all P values<0.05). Whereas they were (211.14±106.25) μmol/L vs. (110.89±59.47) μmol/L and (13.1±7.0) mm vs. (8.8± 3.2) mm, respectively, in patients with X-ray guidance (P<0.05). No complications such as abdominal pain, fever and elevated amylase were found in patients with ultrasound guidance, while 3 patients (5.9%) with X-ray guidence had above complications. Conclusions X-ray is a most effective method in guidance of EBD. However, ultrasound guidence, which may avoid unfavorable factors such as X-ray radiation and allergic contrast agent, has some advantages including real-time display, mobile convenience and emergency bedside application. It can instead of X-ray in performance of endoscopic nasobiliary drainage and endoscopic retrograde biliary drainage in patients with bile duct stone and mild narrow ducl caused by tumors.

Objective To investigate the learning curve of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair.Methods The clinical data of 450 cases of patients who received laparoscopic inguinal hernia repair by the same group of surgeons from December 2012 to August 2016 in our hospital were sequentially divided into three groups,with 150 cases in each group.The cases of each group who received TEP inguinal hernia repair were extracted and enrolled into group A,B and C.The preoperative,intraoperative and postoperative indicators were compared among the three groups.Results Before operation,no statistically significant difference was found in age,gender,incidence rates of scrotum hernia,recurrent hernia and bilateral hernia,and types of hernia among the three groups (P＞0.05).And there was no statistically significant difference in incidence rates of postoperative urinary retention,analgesia and seromas,and hospitalization expenses among the three groups (P＞0.05).During operation,differences in conversion rate,operative time and volume of blood loss among the three groups were statistically significant (P＜0.05).Moreover,statistically significant differences in conversion rate,operative time and volume of blood loss were found between group A and group B (P＜0.05),while there was no statistically significant difference between group B and group C (P＞0.05).The regression curves were drawn based on operation time,volume of blood loss and the number of cases,which estimated the inflection point was 150.Conclusion The learning curve of TEP inguinal hernia repair include approximately 150 cases of laparoscopic inguinal hernia repair (including 16 cases of patients received TEP).The TEP inguinal hernia repair operation during the learning curve can be safety on the basis of preoperative evaluation and appropriate case selection.

BACKGROUND: In recent years, the immunoregulatory effects of mesenchymal stem cells (MSCs) can be used to induce immune tolerance. OBJECTIVE: To evaluate the safety and feasibility of human umbilical cord-derived MSCs (hUC-MSCs) in liver transplantation patients. METHODS: hUC-MSCs were cultured and identified. After approved by the Medical Ethics Committee, a total of 50 patients were randomly divided into experimental group and control group according to the proportion of 1:1. In the experimental group, hUC-MSCs were perfused by the portal vein during the operation and infused into the jugular vein on the 3rd day after the operation. The injection dose was 1×106/kg (prepared as 50 mL of cell suspension). Both groups received standard immunosuppressive regimens. Blood biochemistry and immune function indicators were detected preoperatively and at postoperative days 3, 7, months 1, 2, 3, 6, 12. Acute and chronic rejection rates, incidence of infection, and incidence of transplantation-related complications were recorded. RESULTS AND CONCLUSION: (1) At 3 and 7 days after the operation, the percentage of peripheral blood CD4+CD25+ cells (regulatory T cells) in the experimental group was significantly higher than that in the control group (P < 0.05). The percentage of CD4+ cells (helper/inducer T cells) and ratio of CD4+/CD8+ T lymphocytes were significantly lower in the experimental group than the control group (P < 0.05). (2) There was no significant difference in postoperative alanine aminotransferase and total bilirubin levels between the two groups (P > 0.05). (3) The incidence of abnormal liver function in the experimental group was significantly lower than that in the control group (P < 0.05). (4) The incidence of transplantation-related complications and the rate of infection showed no significant difference between the two groups (P > 0.05). Overall, the intravenous infusion of hUC-MSCs is safe and feasible in liver transplantation patients, which in early stage can promote the the proliferation and activation of CD4+CD25+ cells (regulatory T cells), reduce the percentage of CD4+ cells (helper/inducer T cells) and lower the ratio of CD4+/CD8+ T cells, thereby improving the immune status in liver transplantation patients.

Objective To observe the clnical effects of influence of tanshinone type ⅡA sulfonate on preventing hepatic artery thrombosis after transplantation.Methods A total of 60 patients after liver transplantation were randomly individed into the treatment group and control group, each 30 patients. The treatment group received tanshinone ⅡA sodium sulfonate treatment (60 mg qd, ivgtt continuous 10d) , while the control group used conventional heparinization. The blood coagulation index and the thrombelastograph variables were detected after 7 days and the hepatic artery resistance index (RI) was detected by using Doppler ultrasonography. The postoperative complications and mortality rates were analyzed.Results Although it had little improvement on the coagulation function after liver transplantation, tanshinone ⅡA sodium sulfonate had significant improvement on the time of thrombelastograph parameters reaction (6.35 ± 1.59 minvs. 5.21 ± 1.37 min,t=2.453) and maximum amplitude (58.07 ± 5.42 mmvs. 61.67 ± 5.63 mm,t=-2.532). It showed that RI have significantly statistical difference between the two groups after treatment (0.73 ± 0.11vs. 0.62 ± 0.10;t=-2.948,P<0.01). During the trial, the control group had 2 cases of postoperative complications, HAT and bleeding.Conclusions The Tanshinone ⅡA sodium after liver transplantation can improve the clotting mechanism, preventing HAT.
