Objective To evaluate the clinical effect of acupuncture as an adjuvant therapy for acute pancreatitis (AP).Methods We retrieved the databases ofCNKI,VIP,Wanfang,PubMed,EMBase,and Cochrane Library,selected the relevant randomized clinical trials (RCTs) of AP treated with routine western medicine as control group and treated with routine western medicine combined with acupuncture therapy as trial group.And then,the quality of the qualified RCTs was evaluated,and the end-point outcomes of the RCTs were analyzed by Meta-analysis.Results A total of 7 RCTs involving 371 AP patients were included into the analysis.The time for abdominal pain relief(WMD =-1.44;95％CI:-2.38,-0.50),time for abdominal distension relief (WMD =-2.50;5％CI:-4.07,-0.73),time for the restart of anal exhaust(WMD =-1.79;95％CI:-3.73,-0.14),time for defecation (WMD =-1.95;95％CI:-3.51,-0.39),time for the restart of bowel sound(WMD =-1.39;95％CI:-2.44,-0.34),time for blood amylase becoming normal(WMD =-2.09;95％CI:-3.22,-0.96),and hospitalization time (WMD =-3.70;95％CI:-6.04,-1.36) in the trial group were less than those in the control group,and the differences of the above indexes except for the time for the restart of anal exhaust were significant (P ＜ 0.05).Conclusion Acupuncture as an adjuvant therapy is effective for improving the gastrointestinal function of AP patients,and shortening time for blood amylase becoming normal and hospitalization time.However,due to the low methodological quality,more well-designed randomized controlled trials are needed to confirm the therapeutic effect of acupuncture therapy for AP.

OBJECTIVE: To develop methods of extraction and purification of Cterminal NUDT9 homology domain of human transient receptor potential melastatin 2 (TRPM2) channel. METHODS: After sonication and centrifuge of strain Rosetta (DE3) which was induced by isopropylthio-β-D-galactoside, GST-NUDT9-H was collected after the binding of supernatant with GST beads and eluted with reduced glutathione. Then the elution buffer containing fusion protein was purified by size exclusion chromatography after concentration and centrifuge. Finally, with the cleavage of thrombin and binding with the GST beads, NUDT9-H with high purity in supernatant was collected. RESULTS: The GST-NUDT9-H fusion protein was stabilized with lysis buffer containing 0.5% n-dodecyl -β-d-maltoside (DDM), and wash buffer containing 0.025% DDM in size-exclusion chromatography system, and finally the NUDT9-H with high purity was obtained after cleaved by thrombin (1 U/2 mg fusion protein) for 24 h. CONCLUSIONS Due to the poor stability of NUDT9-H, it is necessary to add DDM in extraction and purification buffer to stabilize the conformation of NUDT9-H, so as to increase its yields and purity.
