Objective To study the influence of bFGF gene transfected bone marrow-derived mesenchymal stem cells (BMSCs) on the inflammatory cytokines of COPD rat. Methods The BMSCs were separated from SD rat and cultured and then bFGF gene was imported to BMSCs by liposome transfection method. The samples were prepared into six groups: normal control group, COPD group (A), BMSCs group (B), pcDNA3.1-BMSCs group (C), bFGF-pcDNA3.1-BMSCs group (D), and bFGF group (E). The expressions of TNF-α and IL-1β by QRT-PCR were detected. Results Compared with COPD group, TNF-α and IL-1β genes from groups B to D dropped significantly (P < 0.05). The changes of TNF-α and IL-1β genes among groups B to D showed no significant difference (P > 0.05). Conclusion BFGF transfected BMSCs, sample BMSCs and pcDNA3.1 transfected BMSCs can inhibit the expression of inflammatory cytokines of TNF-α and IL-1β, but there is no obvious advantage in comparison to bFGF transfected BMSCs and sample BMSCs in respect of inhibiting the expression of inflammatory cytokines of TNF-α and IL-1β.

BACKGROUND:There is no consensus on the choice of anatomic plate or dynamic hip screw for the treatment of intertrochanteric fracture. Current research is limited to smal-sample studies, and it is difficult to carry out a large-sample multicenter analysis. OBJECTIVE:To carry out Meta-analysis about the literature on anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures, in order to evaluate the efficacy of anatomic plate versus dynamic hip screw in the treatment of intertrochanteric fractures. METHODS:The PubMed database (1995-2013), EMCC database (1995-2013), CBM database (1995-2013), CNKI database (1995-2013), VIP database (1989-2013) and Wanfang database (1995-2013) were searched by computer to col ect the control ed trials of anatomic plate versus dynamic hip screw for the treatment of intertrochanteric fractures. Then, the retrieved studies were screened according to predefined inclusion and exclusion criteria. The quality of the included studies was evaluated to extract useful y data, and Meta-analysis was performed by using the RevMan5.0 software. RESULTS AND CONCLUSION:A total of 19 control ed trials were included with a total of 1 730 cases. Among them, 764 cases were belonged to the anatomic plate group, and dynamic hip screw group included 966 cases. The Meta-analysis results indicated that there were no statistical y significant differences in fracture healing time, prognosis excellent and good rate and postoperative complications between two groups (P=0.34, 0.58, 0.80);the operative time, intraoperative blood loss and postoperative drainage volume in the anatomic plate group were lower than those in the dynamic hip screw group (P<0.000 01). The results indicate that anatomic plate and dynamic hip screw have the similar clinical efficacy for the treatment of intertrochanteric fractures, but the anatomical plate has relatively simple operation and less bleeding. Due to the poor quality of the included literatures and high bias occur and influence the effect, so more wel-designed multi-center randomized control ed trials should be performed to provide high-quality evidence.

Objective To establish a stable brain injury model with pancreatitis and explore the mechanism of brain injury resulting from severe acute pancreatitis (SAP) in experimental rat models. Methods Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham operation (SO) group, SAP group and trypsin group, with eight rats in each. Brain tissue and pancreas tissue specimens were collected at 12 h after treatment. Death rate in each group was evaluated; the level of tight junction protein zonula occludens 1 (Zo-1) was determined by enzyme-linked immunosorbent assay. The ultrastructure of the brain tissues was examined using transmission electronic microscope; pathological changes in the brain tissues were observed with HE staining. Results The death rate was increased significantly in SAP group compared with that in trypsin group; no rats in SO group died. Zo-1 level was obviously lower in SO group than in SAP group and trypsin group (P<0.05). The ultrastructural changes were seen in the latter two groups, including obvious neuronal cell swelling, capiliary stasis, increased vascular permeability, thrombosis and cell apoptosis. Conclusion Trypsin may cause brain injury with pancratitis. The death rate of SAP model established by trypsin was low. We have provided a stable animal brain injury model for further study and treatment of brain injury.
