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.

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.

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.

Objective: To investigate the effects of Radix Ginseng and Radix Notoginseng formula on expressions of vascular endothelial growth factor receptor-2 (VEGFR-2) and hypoxia-inducible factor-1alpha (HIF-1alpha) in ischemic myocardium of rats with acute myocardial infarction. Methods: A total of 100 Wistar rats were randomly divided into normal control group, sham-operated group, untreated group, metoprolol (Betaloc) group, and high- and low-dose Radix Ginseng and Radix Notoginseng formula groups. Acute myocardial infarction was induced in the untreated group, Betaloc group, and high- and low-dose Radix Ginseng and Radix Notoginseng formula groups by left anterior descending coronary artery ligation. After 12-day treatment, microvessel density (MVD) in ischemic myocardium was detected by immunohistochemical method, while expressions of VEGFR-2 and HIF-1alpha proteins were detected by Western blotting, and expressions of VEGFR-2 and HIF-1alpha mRNAs were detected by real-time fluorescent quantitative polymerase chain reaction. Results: MVD in the untreated group was increased significantly, higher than those in the normal control group and the sham-operated group (P<0.05) and lower than those in the high- and low-dose Radix Ginseng and Radix Notoginseng formula groups and Betaloc group (P<0.01). VEGFR-2 and HIF-1alpha protein and mRNA expressions in the untreated group were higher than those in the normal control group and the sham-operated group (P<0.05). VEGFR-2 and HIF-1alpha protein and mRNA expressions in the high- and low-dose Radix Ginseng and Radix Notoginseng formula groups and Betaloc group were higher than those in the untreated group (P<0.05). There was a significant difference between the high- and low-dose Radix Ginseng and Radix Notoginseng formula groups (P<0.05). Conclusion: Radix Ginseng and Radix Notoginseng extract can up-regulate the protein and mRNA expressions of VEGFR-2 and HIF-1alpha and increase MVD in ischemic myocardium to improve myocardial ischemia so as to promote the development of collateral circulation.

AIM: To demonstrate the protective effects of ST-1 against focal cerebral ischemia-reperfusion injury in rats.METHODS: The model of focal ischemia-reperfusion was induced by middle cerebral artery occlusion 2 h followed by reperfusion 22 h in rats.Neurological deficit scores were evaluated.Infarct size,malondialdehyde(MDA) content and superoxide dismutase (SOD) activity were measured,pathological changes of neurons in hippocampal CA1 region were observed.RESULTS: Compared with vehicle group ST1 at dose of 10 and 20(mg?kg~(-1)) could reduce the infarct size,MDA content,enhance SOD activity and relieve neurons injury in hippocampal CA1 region in dose-dependent way;ST-1 at dose of 20(mg?kg~(-1)) could also improve neurological function.CONCLUSION: ST-1 can protect brain tissue from focal ischemia-reperfusion injury.

Objective To report the method and outcomes ot arthroscopic examination and removal of the.loose bodies from the posterior compartments of the knee. Methods Four mm 30? arthroscope was used to examine the patients with osteoarthritic loose body in the politeal fossa on the preoperative roentgenograms via posterolateral and posteromedial portals. An assistant portal at 1 - 1.5 cm in front of the standard portals was made, and loose bodies were removed arthroscopically. Postoperative algesia on the leg and foot, active flexion and extension of the malleolus, toe and phalanxes, and the lateral stress test of the knee were observed. Results Of the three hundred and sixty-four cases undergone knee arthroscopy during January 1999 to December 2000, 17 case had osteoarthritis and loose bodies in the posterior compartment on the roentgenograms. Loose bodies were found in the posterolateral portal in 9 cases, which were removed arthroscopically. Howerver, no loose body was found via the posteromedial portal. The mean duration of follow-up was 14. 88 months. Except one case with subcutaneous loose body was overlooked and one patient developed hematoma, there was no neurovascular or ligamentous complications. Conclusion It is safe and possible to use 4 mm 30? arthroscope to examine the posterior compartments of the knee and to remove loose bodies.

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 analyze the application value of radionuclide myocardial perfusion imaging in the localization and diagnosis for stable angina pectoris in clinical practice. Methods: A total of 70 patients who had been diagnosed with stable angina pectoris (SAP) were enrolled, and all patients underwent ATP-loaded ATP-99Tcm-MIBI (99Tcm-MIBI) myocardial perfusion imaging (MPI) and coronary angiography (CAG) were used to compare the accuracy of MPI imaging in localization and diagnosis for SAP. Results:In the 70 cases of patients with two methods of examination: ①In MPI diagnosis, positive patients were 50 cases, and the positive predictive value of SAP, sensitivity, negative predictive value and specificity were, respectively, 92.0%, 90.2%, 75.0% and 78.9%. There were 45 patients were consistently diagnosed as SAP by the two methods and the total compliance rate was 90.0%. ②in 70 patients, 51 cases were diagnosed as SAP by CAG examination, the positive rate was 72.9%; ③in 50 MPI positive patients, 46 patients were consistent with the results of CAG diagnosis, and the positive rate was 92.0%. The difference between the two methods was statistically significant (x2= 5.72, P<0.05). Conclusion: 99Tcm-MIBI myocardial perfusion imaging can be used as a gatekeeper in patients with stable angina pectoris, and has high application value in the location and diagnosis for stable angina pectoris. The diagnosis and treatment links of stable angina pectoris can save costs and provide a reliable evidencet for clinical practice.
