Objective To study the growth effect of human cholangiocarcinoma cell line QBC939 treated by norcantharidin (NCTD) and preliminary illustrate the potential mechanism.Methods The human cholangiocarcinoma cell line QBC939 was detected by MTT assay,flow cytometry,immunocytochemistry after the treatment of NCTD in vitro.Results NCTD displayed inhibitory effect on growth of QBC939 from different doses of 0.125,0.75,2.5,10,120 μg/ml after 48 h (P ＜0.05).It was in a dose and time dependent manner.Dose-effect curve was drawn and IC50 value was (3.66±1.14) μg/ml.The flow cytometric profiles showed that the rate of cell apoptosis enhanced following increasing the concentration of NCTD[(8.6±0.4) ％,(17.6±0.3) ％,(22.9±0.4) ％,(25.5±0.9) ％ and (31.1±1.5) ％,respectively]and cells blocked in the G2/M phase after treatment with 2.5 μg/ml NCTD[(14.1±1.0) ％ and (5.7±0.3) ％].The expression of the protein caspase-3 elevated after different concentrations of NCTD co-cultured with QBC939 compare with contrast group.Conclusion NCTD has an inhibitory effect on proliferation of QBC939 cell line,and the mechanism might be related to the induction of cell apoptosis and blockade of cell cycle.

Objective To evaluate the safety and effectiveness of immunosuppression regimens,postoperative complications,dead causes and risk factors of lung transplantation (LTx).Methods The immunosuppression regimens and clinical data of 100 patients with end-stage lung diseases receiving LTx in our hospital were retrospectively analyzed between Sept.2002 to Dec.2010.There were 72 patients subject to single LTx and 28 patients to bilateral LTx,amongst them 61 patients received LTx under circulation support,including 5 cases of cardopulmonary bypass (CPB) support and 56 cases of extracorporeal membrane oxygenation (ECMO) support.The immunosuppression regimens including Cyclosporin,mycophemolate Mofeil and corticosteroids were utilized in 53 recipients before the year of 2007,and Cyclosporin was switched to Tacrolimus in 47 patients after 2007.All the patients received Daclizumab or Basiliximab as immunosuppression induction regimens.Results The 1-,2-,3-and 5-year survival rate after LTx was 73.3％,61.6％,53.5％ and 40.7％ respectively.The mean survival time post-transplant in the patients who received Cyclosporin-based regimens and Tacrolimus-based regimens were (36.57 ± 3.44) months and (35.00 ± 2.33) months,repectively,with no significant differences (P＞0.05).The main causes of mortality included primary graft dysfunction (PGD),acute rejection (AR),bronchiolitis obliterans (BOS) and sepsis.The incidence of AR and BOS in Tacrolimus group was significantly lower than that in Cyclosporin grou (P ＜0.05),but the incidence of diabetes mellitus was significantly higher in Tacrolimus group.Analysis of Spearman rank correlation revealed that there was a direct correlation between the incidence of AR and BOS (r =0.340,P＜0.01).The use of circulation support,diagnosis of IPF,postoperative complications such as AR,BOS and infection were associated with decreased survival time postoperatively,in both univariate and multivariate proportional hazards regression models (P＜0.05).Conclusion Cyclosporin-and Tacrolimus-based regimens were both effective immunosuppression strategies postoperatively,Consummate follow-up surveillance and prompt treatment of complications were the key points in prolongation of survival time and improving quality of life after LTx.

Objective To evaluate the charateristics of biliary stricture after orthotopic liver transplantation(OLT) by ultrasound. Methods Diametes,thickness,characteristic echo of bile were observed by ultrasound in 41 patients with biliary stricture after OLT,and the results were compared with those of 46 patients without biliary complication after OLT.Results The diameter of intrahepatic bile,thickness of bile,incidence of intrahepatic bile dilation or hyperechogenicity in biliary stricture patiens were higher than those in patients without biliary complication,there were significant differences between two groups(P＜0.05).Conclusions The series of ultrasonographic character such as bile dilation,thickeness or hyperechogenicity of biliary wall,thin of bile duct are available to diagnose biliary stricture.

Objective:To analyze the clinical characteristics of adult abdominal migraine (AM), and improve the understanding and the accuracy of diagnosis of this disease.Methods:A case of adult AM diagnosed in the First Affiliated Hospital of Zhengzhou University in October 2019 was reported, and patients diagnosed with AM in the medical literature from January 2004 to May 2020 were searched and summarized.Results:A total of 634 articles were retrieved, among which 14 articles reported 17 adult AM patients,totally 18 adult AM patients (11 females),including the case diagnosed in the First Affiliated Hospital of Zhengzhou University. Only two cases were diagnosed within one year after the onset, and the other cases were diagnosed several years later, of which the longest diagnostic delay was 37 years. The location and nature of abdominal pain were diverse. The median frequency of episodes was 2.5 times per month. Sixteen patients had a duration of 2-72 hours per attack, and the longest one lasted for four days. Fourteen patients had nausea, 13 had vomiting, and seven had headache. Fifteen patients had a personal or family history of migraine. Sixteen patients′ episodes were separated by weeks to months. Because nonsteroidal anti-inflammatory drugs were not beneficial to adults with AM, abortive triptan therapy was recommended and anesthetics were considered when necessary. All patients responded to prophylactic migraine therapies.Conclusions:Adult AM is a rare disease. Patients with unexplained, recurrent and moderate to severe abdominal pain, combined with headache, a personal or family history of migraine, are highly suspected of having AM. Early diagnosis and prophylactic migraine therapies could contribute to good prognosis.
