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 The special features of discoid meniscus(DM) symptoms， the relationship between the symptoms and the signs of DM, the type and scale of DM injury as well as the prognosis were studied. Methods According to the analysis of 64 cases of DM diagnosed by arthroscopy, a comparitive analysis was made and the following topics were addressed: the distribution of the complete type of DM in patients of different age groups, the signs of locking and non-locking, with or without effusion, snapping and non-snapping, a comparison of the distribution of the snapping in different groups of injury types, a comparison of the distribution of the flexion contracture in different types of injury, a comparison of the distribution of the rates of the total and subtotal menisectomy in different groups divided according to the period of pain, the presence of effusion, the presence of locking, snapping, quadriceps atrophy and extension function. The data was analysed statistically. Results There is significant difference in the distribution of the complete type DM between 20 and over 20-years of age(P0.05). Conclusion The complete type of DM was mostly seen in cases below 20 years of age and was rarely seen in cases with the locking sign. Snapping sign was mostly seen in cases of complicated and extensive injuries and was one of the indications of arthroscopic surgery. Knee flexion contracture was mostly seen in cases of longitudinal and extensive injuries. The estimation of the results of arthroscopic surgery for DM is difficult on the bases of the clinical symptoms and signs.

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.

Colorectal cancer (CRC) is one of the most common gastrointestinal malignancies with poor prognosis and high mortality.SEPT9 gene is a tumor suppressor gene and plays an important role in the end of cell division.Studies have shown that methylation of SEPT9 gene could be used in the early diagnosis of CRC.This article reviewed the advances in study on SEPT9 gene methylation in the screening and diagnosis of CRC.

ve To assess the protective effect of L-arginine on vascular endothelial cell during cardiopulmonary bypass(CPB). Methods 12 adult healthy mongrel dogs of either sex weighing 10-15kg, were divided into L-arginine group (group L, n=6) and control group (group C, n=6) . Femoral artery and vein were cannulated for monitoring of MAP and CVP. Right internal jugular vein was cannulated with Swan-Ganz catheter for hemodynamic monitoring. L-arginine 100 mg?kg-1 was administered intravenously before CPB followed by continuous intravenous infusion at 10mg?kg-1.min-1 to the end of CPB in group L. Control group was treated as group L except the administration of L-arginine. Venous blood samples were taken before CPB, 5min after CPB was started, 15, 45min after aortic cross-clamping and 15, 30min after release of aortic cross-clamp for determination of the plasma levels of metabolites of nitric oxide (NO2- and NO3-), malondialdehyde (MDA) and von Willebrand Factor(vWF). Hemodynamic parameters were measured before CPB, 15 and 30min after release of aortic clamp. Specimens of tissue from femoral artery and descending aorta were taken for microscopic examination at 15,45 min after aortic cross-clamping and 30min after release of aortic cross-clamp.Results There was little difference in plasma NO2- and NO3-concentrations before CPB between the two groups. NO2- and NO3- levels increased significantly after CPB in both groups but were significantly higher in group L than those in group C (P

It is pointed out that nursing personnel at the clinical forefront are a high-risk group for occupational injuries. The risk factors include: lack of knowledge on occupational injuries and their prevention in elementary and continuing education; various factors affecting nursing personnel's physical health, such as drug-dissolving facilities for the special purpose of chemotherapy, imperfect clean work station or relatively hermetical drug-dissolving environment ; increase of diseases that could be easily contracted in the hospital, such as hepatitis B, with the stabbing of nursing personnel by sharp medical instruments infected by blood or saliva being the main route of their occupational infection. The disadvantageous impact of occupation on their health puts nursing personnel under great psychological pressure. In order to safeguard their physical and mental health, it is imperative to put knowledge on hospital infection, occupational injuries and health maintenance on the curriculum of medical colleges and universities, reinforce nursing personnel's training in occupational safety, and take measures to prevent occupational injuries, such as using disposable gloves when dispensing medicines in chemotherapeutic drug centers.
