Liver fibrosis is a primary cause of liver cirrhosis, and even hepatocarcinoma. Recently, the usage of mesenchymal stem cells (MSCs) has been investigated to improve liver fibrosis. It has been reported that the differentiation, proliferation and migration of MSCs can be regulated by traditional Chinese medicine treatment; however, the mechanisms are still unclear. In this article, the authors review the characteristics of MSCs such as multidirectional differentiation and homing, and its application in animal experiments and clinical trials. The authors also list areas that need further investigation, andlook at the future prospects of clinical application of MSCs.

OBJECTIVETo investigate the effects of closed reduction and ulna intramedullary nail fixation for the treatment of fresh Monteggia fractures of Bado type I and II in children.

METHODSTwenty-three children patients with Monteggia fracture during July 2010 to September 2013 were treated by closed reduction and ulna intramedullary nail fixaion including 18 boys and 5 girls with an average age of 9.3 years old ranging from 6 to 13 years old. Among them,15 cases were Bado type I and 8 cases were Bado type II. There were 9 cases with radial nerve injury. The operation time,the recovery of nerve injury, the fracture healing and the function of elbow were observed and recorded.

RESULTSAll patients were followed up for 6 to 24 months (12 months on average). All patients were obtained bone healing. According to Anderson standard, at the final follow-up, 20 cases got excellent result, 2 cases got good result, and one case got fair result.

CONCLUSIONTreatment of the fresh Monteggia fractures in children by closed reduction and ulna intramedullary nail fixation has advantages of simple operation, less trauma and good results.

OBJECTIVE： Evaluating clinical efficacy of ceftriaxone in the treatment of lower respiratory tract infections METHODS： Applying meta－ analysis to evaluation of clinical efficacy of ceftriaxone， cefotaxime and cefuroxime in the treatment of lower respiratory tract infections RESULTS ＆ CONCLUSION： Ceftriaxone is worthy of popularization and application in clinical practice because of its better efficacy and lower cost

The effects of solid-state fermentation (SSF) and submerged fermentation (SmF) and the addition of olive oil on the whole-cell lipase production by Rhizopus chinensis CCTCC M201021 were investigated.Compared with SSF, higher biomass, hydrolytic activity and synthetic activity were observed in SmF.By the addition of olive oil, the synthetic activity of whole-cell lipase in both fermentations was enhanced significantly, especially in SmF, while the biomass and the hydrolytic activity were also increased.Hence, olive oil serves as both carbon source and the inducer of lipases in fermentation.It was also found that the synthetic activity of whole-cell lipase was not accordant to the hydrolytic activity during both SmF and SSF, suggesting that isoenzymes with difference in lipase properties may be produced by Rhizopus chinensis.

This study based on an ethical review of the kidney donation from a young man to his elder relative.We discuss the problems existing in present field of intra-vital organ transplantations,as well as its risk and the ethics review mode.It is recommended that ethics review is performed as a complete procedure,which should not only present in certain format,but also emphasize weighing the advantages and disadvantages of both patients and donors;intra-vital organ transplantations between relatives should also follow the principle of "no compensation and non-commercialization";hospitals should give out the judgment under sufficient considerations of both patients' and donors' benefits within the scope of laws,as well as taking into account of other factors such as prospective outcome of the operations,rather than barely basing on the risk probabilities.
