Objective To evaluate the value of IL15mRNA determination in the early diagnosis and differential diagnosis of acute rejection(AR) after liver transplantation.Methods RT-PCR was used to detect the mRNA of IL-15 in serum and bile on the 30th day after liver transplantation in 43 patients subject to orthotopic piggy-back liver transplantation.Serum and bile of the patients were cultured for bacteria.The acute rejection was confirmed pathologically. Results Acute rejection(occurred) in 16 out of 43 cases as the AR group and bacterial infection(BI) in 12 cases as the BI group.The (remaining) 15 patients were uneventful as the control group.Before diagnosis of AR and BI,the gene expression rate of IL-5 in bile was significantly higher in AR group((62.5 %)) than in BI group((16.7 %)) and control group((13.3 %))(P

In order to evaluate the applied value of soluble intracellular adhesion molecule-1 (sICAM-1) in acute rejection (AR) following liver transplantation, the expression of sICAM-1 protein was sequentially detected by using ELISA in serum and bile of 43 patients receiving liver transplantation. In AR group, the expression levels of sICAM-1 protein were increased 3 days before and immediately on the establishment of AR diagnosis, and there was significant difference in the expression of bile between AR group and control group (P<0.01). After reversion of AR with hormone intensive therapy, there was significant difference in the sICAM-1 protein expression of serum and bile between AR group and control group. It was concluded that the sequential detection of sICAM-1 protein level in serum and bile was a reliable and noninvasive method for the early diagnosis of AR after liver transplantation and was valuable to observe the curative effects of anti-AR therapy.

Objective To investigate the effects of preoperative jaundice relieving on hemihepatectomy of hilar cholangiocarcinoma.Methods The clinical data of 18 patients who received preoperative percutaneous transhepatic cholangiography and drainage (PTCD) or endoscopic nasobiliary drainage (ENBD) before hemihepatectomy at the Tongji Hospital of Huazhong University of Science and Technology from January 2007 to January 2012 were retrospectively analyzed.The condition of the 18 patients (jaundice relieving group) was compared with that of 24 patients (non-jaundice relieving group) who did not receive PTCD or ENBD before hemihepatectomy.The differences in the pre-and postoperative blood loss,blood transfusion,operation time and postoperative incidence of complications between the 2 groups were analyzed.All data were analyzed using the t test or chi-square test.Results After PTCD or ENBD,the levels of total bilirubin (TBil),direct bilirubin (DBil),alanine aminotransferase (ALT) were (27 ± 5) μmol/L,(22 ± 6) μmol/L and (52 ± 42) U/L,which were significantly lower than (287 ± 120)μmol/L,(212 ± 86)μmol/L,and (267 ± 180)U/L before PTCD or ENBD in the jaundice relieving group (t =4.33,6.61,4.19,P ＜0.05).In the jaundice relieving group,left hemihepatectomy was performed on 14 patients,and right hemihepatectomy on 4 patients,and the radical resection rate was 16/18.In the nonjaundice relieving group,left hemihepatectomy was performed on 11 patients,and right hemihepatectomy on 13 patients,and the radical resection rate was 83.3％ (20/24).There was no significant difference in the radical resection rate between the 2 groups (x2 =1.09,P ＞ 0.05).The operation time,volume of intraoperative blood loss,volume of blood transfusion were (5.0 ± 0.8) hours,(562 ± 207) ml and (430 ± 317) ml in the jaundice relieving group,and (6.3 ± 1.5)hours,(815 ± 463)ml and (750 ± 146)ml in the non-jaundice relieving group,with significant differences between the 2 groups (t =4.77,7.80,4.65,P ＜ 0.05).The incidences of postoperative complications,bleeding and postoperative hepatic failure were 3/18,1/18 and 1/18 in the jaundice relieving group,and 75.0％ (18/24),33.3％ (8/24) and 33.3％ (8/24) in the non-jaundice relieving group,with significant differences between the 2 groups (x2=5.14,7.58,7.58,P ＜ 0.05).Conclusion Preoperative jaundice relieving could shorten the operation time and reduce the volume of intraoperative blood loss and the incidence of postoperative complications.

Objective To investigate the resident performance on preoperative anesthetist visit in Beijing hospitals,thereby providing introduction for further training.Methods A self-designed questionnaire was distributed among the anesthesia residents who were receiving anesthesia residency training in Beijing through WeChat.The questionnaire covers geographic data of the residents,information on preoperative visit and existing training program.Results160 questionnaires were reclaimed.History-taking and physical examination were not comprehensive in many residents,the nature of surgery was not evaluated by most residents.The capacity of risk assessment and risk informing were not competent in many residents.The most desired training methods for preoperative visit were scenario simulation and bedside observation.Conclusions Scenario simulation with standard patient may have a promising prospect in preoperative anesthetist visit training.

Objective To observe the clinical effect and security of autohemotherapy combined with bacillus calmette-guerin polysaccharide and nucleic acid in treatment of facial steroid-dependent dermatitis.Methods The 74 patients with facial steroid-dependent dermatitis were divided into treatment group (38patients) and control group (36 patients) according to the treatment method.The patients in treatment group were treated with autohemotherapy combined with bacillus calmette-gnerin polysaccharide and nucleic acid 1 ml muscle injection,every 3 days a time for 4 weeks.The patients in control group were treated with bacillus calmette-guerin polysaccharide and nucleic acid,every 3 days a time for 4 weeks.The effect was compared between the two groups.Results The total effective rate in treatment group was 84.2％(32/38),in control group was 63.9％(23/36),there was significant difference between the two groups (P ＜ 0.05).No serious adverse reaction was found in two groups.Conclusion Autohemotherapy combined with bacillus calmettegnerin polysaccharide and nucleic acid is safe and effective in treatment of facial steroid-dependent dermatitis.

ObjectiveTo investigate the relationship between Dicer expression and clinicopathological characteristics and prognosis by detecting the expression of Dicer in hilar cholangiocarcinoma tissues and cells.MethodsThe expression of Dicer in tissues was detected using immunohistochemistry.Western blotting and RT-PCR were used to investigate Dicer expression in QBC939 and HIBEpic cells.The relationship between Dicer expression and clinicopathological characteristics was analyzed.A Kaplan-Maier analysis was performed to analyze the disease-free survival (DFS) and overall survival (OS) after radical surgical resection of hilar cholangiocarcinoma.ResultsWhen compared to control,Dicer was significantly down-regulated in hilar cholangiocarcinoma tissues (P＜0.05) and in QBC939 (P＜0.05).The expression of Dicer was higher in well differentiated adenocarcinoma than poorly and moderately differentiated tumours. Univariate analysis showed low expression of Dicer protein was significantly correlated with short disease-free survival and overall survival of patients with hilar cholangiocarcinoma after radical surgical resection (P＜0.01). Multivariate analysis revealed that the expression of Dicer was the most important factor for predicting prognosis after radical surgical resection of hilar cholangiocarcinoma (P＜0.05).ConclusionsDicer could be used as a prognostic marker for hilar cholangiocarcinoma.

Objective To investigate the effect of lysimachia capillipes(LC) on proliferation of human pancreatic cancer cell line BxPC-3 in vitro and explore the potential mechanism.Methods BxPC-3 cells were treated by LC in different concentrations of 2,4,8,16,32,64 μg/ml for 48 and 72 hours,respectively,using untreated cells as control.The survival rate of BxPC-3 cells was measured by MTT method.The half inhibition concentration (IC50) of LC was determined by drawing growth curve.BxPC-3 cells were treated by LC in the concentration of IC50 (LC group),and cell apoptosis and cell cycle were examined by using flow cytometry.The protein expression of PARP and capase-3 was detected by Western blotting.Results LC in the concentration of 8-32 μg/ml inhibited the survival rate of BxPC-3 cells in a dose-dependent manner.After exposure to 15 μg/ml LC for 48 h,the apoptosis rate of BxPC-3 cells was increased [(17.3 ± 0.31)％ vs (1.5 ± 0.22) ％],but the cell cycle was not affected.The expression of caspase-3 protein was up-regulated [(2207.2 ± 92.0) vs 149.1 ± 10.2] and PARP protein was down-regulated [(36.1 ± 4.8) vs 1593.4 ±29.7] than control group,and the differences were statistically different (all P value ＜ 0.05).Conclusions LC can inhibit the growth of BxPC-3 cells,and the potential mechanism was associated with the induction of cell apoptosis by LC via upregulating caspase-3 protein expression and decompsing PARP protein.

Previous studies have shown that miRNAs participate in a wide range of biological functions and play important roles in various human diseases including cancer. We found miR-146b-5p significantly dysregulated in human pancreatic cancer cells by qRT-PCR. To demonstrate its function and regulation mechanism, we overexpressed miR-146-5p by transfecting the mimics. Our data showed that miR-146b-5p overexpression significantly reduced the abilities of migration and invasion of MIA PaCa-2 pancreatic cancer cells. Furthermore, we found that matrix metalloproteinase 16 (MMP16) was a downstream target of miR-146b-5p by dual-luciferase reporter assay. Altogether, our findings suggest that miR-146b-5p may be involved in pancreatic cancer cell migration and invasion by targeting MMP16, and miR-146b-5p may be a potential therapeutic target for the pancreatic cancer.
