1.Clinical efficacy of traditional Chinese medicine/herbal decoction combined with ursodeoxycholic acid for primary bil-iary cirrhosis:a meta-analysis
Journal of Clinical Hepatology 2015;32(1):68-73
Objective To systematically evaluate the efficacy of traditional Chinese medicine/herbal decoction combined with ursodeoxy-cholic acid (UDCA)in the treatment of primary biliary cirrhosis (PBC),and to provide a reference for clinical medication.Methods Lit-erature published before July 31,2014 was searched in databases as follows:Cochrane Library,PubMed,China National Knowledge Infra-structure (CNKI),Chinese Scientific Journals Full-text Database (VIP),Chinese Biomedical Literature Database (CBM),and Wanfang Data.The randomized controlled trials (RCTs)comparing the efficacy of traditional Chinese medicine/herbal decoction combined with UD-CA versus UDCA alone in PBC patients were included in the analysis.The methodological quality of included trials was assessed and the data were extracted,followed by meta-analysis using RevMan 5.0 software.Results A total of 12 RCTs were included,involving 681 patients with 346 in the test group and 335 in the control group.The results of meta-analysis showed that,after 6 months of treatment,the overall response rate,improvement rate,and biochemical indices of liver function (ALT,ALP,GGT,and TBil)and hepatic fibrosis in the test group were significantly improved compared with those in the control group (all P<0.05).There were no significant differences between the two groups in the immunological indices such as IgA,IgG,anti-mitochondrial antibody (AMA),and AMA M2 subtype (all P>0.05 ). Conclusion Traditional Chinese medicine/herbal decoction combined with UDCA markedly improves the indices of hepatocellular necrosis and cholestasis,degree of hepatic fibrosis,and clinical symptoms in PBC patients after 6 months of treatment,but leads to no significant im-provement in immunological indices.Due to the limited number of included RCTs and patients through systematic evaluation,and the pres-ence of selection bias and publication bias,more double-blind randomized controlled trials with large sample size,multicenter involvement, and high quality are required to provide convincing evidence.
2.Exploration of training mechanisms for young faculty's research capabilities
Chinese Journal of Medical Science Research Management 2012;(6):399-401
Young faculty are an essential part of a university's strength and is important for its sustainable development.And their scientific research capability is associated with the long-term development of the university.At present,there are 4 major problems with the development of young faculty's research capabilities,which include their relatively single academic knowledge structure,insufficient experience in writing proposals,insufficient opportunities for academic exchange,and inequity in resource allocation.Establishing a training mechanism may help solve some of the problems and promot their development.The research management department of a university must abandon erroneous traditional management concepts,provide research training seminars,develop a new mechanism to stimulate academic exchange,design a system for short-term laboratory rotations,and promote the participation of your faculty in major research projects.These may bring about marked improvement in the improvement of young faculty's research capabilities.

4.Clinical features and treatment of breast intraductal papilloma
Chinese Journal of General Surgery 2021;36(3):196-199
Objective:To investigate the clinicopathologic features and diagnostic methods of intraductal papillary(IP)lesions of the breast.Methods:The clinical data of 1 679 patients who had been pathologically diagnosed as having IP were analyzed retrospectively.Results:Nipple discharge is the most common clinical symptom of IP. According to the postoperative pathological results, IP patients were divided into solitary IP group and multiple IP group . Nipple discharge was more common in solitary IP group ( P<0.05). Bloody discharge and duct nipple discharge and discharge in unilateral breast were the most common clinical symptom of IP, though the difference was not significant ( P>0.05). The accuracy of diagnosing IP by fiberoptic ductoscopy(FDS) was 88.66% which was significantly higher than that of breast ultrasound and mammography. Solitary IP patients with nipple discharge undergoing FDS before surgery and lesions were more often detected located in general or level Ⅰ-Ⅱ duct system ( P<0.05). Postoperative follow-up did not show malignant transformation in solitary IP group, while there were 4 cases in the multiple IP group of malignant transformation and higher recurrence rate of IP ( P<0.05). Conclusions:Bloody discharge, single duct nipple discharge and unilateral breast involving 1esion and 1esions located in the general or level Ⅰ-Ⅱ duct system are common clinical features of IP. FDS has advantages in the diagnosis of IP with nipple discharge. For fear of recurrence , and malignant transformation in multiple IP, active postoperative follow-up should be carried out.

BACKGROUND:The state of ischemic penumbra after cerebral infraction determines the final infarct volume. Decreased selective gene expression and protein synthesis, lactic acidosis and cytotoxic edema, salvage therapy of nerve cels, and continous regulation of neurovascular unit in the ischemic penumbra are areas of interest for recovery of neurological function. OBJECTIVE: Taking the neoangiogenesis process of post-infarction as the research point, to investigate the basic law of neovascularization with time and the effect of electroacupuncture intervention on proliferation of local blood vessels. METHODS: Ninety-six Wistar rats were randomly and evenly divided into model and electroacupuncture groups. The rat models of middle cerebral artery infarction were established by suture method. Immediately after modeling, the rats in the electroacupuncture group were given electrical stimulation (15 Hz, 1mA, 20 minutes) at the Renzhong (Du26) acupoint. The rats in the model group received similar procedures with the exception of no treatment. The angiogenesis was observed using double-immunofluorescence labeling for von Wilebrand Factor (vWF) and Ki-67 antibodies at 3, 6, 12, 24, 48 hours and 3, 7, 12 days after middle cerebral artery occlusion. RESULTS AND CONCLUSION:In the model group, vascular endothelial cel proliferation in the peri-infarct region was not observed at 3, 6 and 12 hours, occurred at 24 hours, increased at 48 hours, reached a maximum at 3 days, began to decrease at 7 days, and disappeared at 12 days after middle cerebral artery occlusion. In the electroacupuncture group, vascular endothelial cel proliferation in the peri-infarct region was not observed at 3 and 6 hours, occurred at 12 hours, increased at 24 and 48 hours, peaked at 3 days, began to decerase at 7 days, and disappeared at 12 days after middle cerebral artery occlusion. Compared with the model group, the time at which vascular endothelial cel proliferation started was earlier, and the number of proliferated vascular endothelial cels was greater in the electroacupuncture group. Vascular endothelial cel proliferation in the infarcted regions and contralateral hemisphere was not observed in either group at al designated time points. These results demonstrate that electroacupuncture intervention can improve the prognosis of cerebral infarction by promoting the proliferation of vascular endothelial cels in the peri-infarct region and advancing the time at which vascular endothelial cel proliferation started in rat models of middle cerebral artery occlusion.

Objective To study the effect of hepatectomy operation on circulating tumor cells of liver cancer patients during surgery. Methods Circulating blood was draw from 18 liver cancer patients before and after hepatectomy and 20 healthy volunteers. Blood routine ex-amination for leukocyte enumeration and karyote counting by microscope were taken for every blood samples to compare with the number of leukocytes and karyotes between pre-hepatectomy and post-hepatectomy blood of liver cancer patients. Immunofluorescence and cell culture techniques were used to identify the tumor cells and compare with the numbers and characteristics of the circulating tumor cells in blood sam-ples among all groups. Fluorescent antibodies,AE1/AE3 and CD133 were used to mark tumor cells. Results The number of leukocytes and karyotes in post-hepatectomy blood samples of liver cancer patients increased compared with pre-hepatectomy blood samples. The AE1/AE3 positive cells-samples were more than CD133 positive cells-samples and double positive cells-samples(P<0. 001). AE1/AE3 positive cells of healthy volunteers’ blood were more than post-hepatectomy blood of liver cancer patients(P<0. 05). No significant differences in CD133 positive cells and double positive cells were found among all groups(P>0. 05). There were no significant differences in clone formation rate after cell culture among all groups(P>0. 05). For 3 clone formed samples of liver cancer patients,there were no differences in tumor source, pathologic type and differentiation level. Conclusion The circulating blood of liver cancer patients,non-cancer patients and healthy people all exist circulating tumor cells. Hepatoma resection does not affect the number and characteristics of circulating tumor cells in liver cancer pa-tients’ blood.
