1.Intertrochanteric fractures
Chinese Journal of Orthopaedic Trauma 2004;0(05):-
Intertrochanteric fractures occur mostly in the elderly population. Direction of fracture line, lesser trochanteric fracture, comminution and displacement are the chief concerns in radiological diagnosis of intertrochanteric fractures. Interchanteric fractures can be classified by Evansgrading, Jensens modification of Evansgrading, AO classification, and so on, which are to judge the stability of the fracture. Currently, the basic priciple of management is operation and fixation. The common implants of internal fixation consist of two basic kinds: gliding compression screws with lateral plate, such as dynamic hip screws (DHS), and intramedullary nail fixation, such as Gamma nails and proximal femoral nails. Exteranl fixators are only applied in cases of severe multiple trauma and elderly patients, and artificial joint replacements in those of serere comminuted fractures combined with high osteoporosis.

7.Repair of abdominal wall defects by highly simulated chitosan scaffolds
Chinese Journal of Tissue Engineering Research 2017;21(26):4205-4209
BACKGROUND: Studies have shown that chitosan can improve the proliferation and migration of fibroblasts, promote the synthesis of extracellular matrix, and create a favorable environment for defect healing.OBJECTIVE: To observe the effect of highly simulated chitosan scaffolds in repairing abdominal wall defects in rats.METHODS: Sixty adult Sprague-Dawley rats were used to make animal models of abdominal wall defects, and then model rats were randomly divided into two groups: experimental group and control group followed by implantation with the highly simulated chitosan scaffold and polypropylene mesh, respectively. At 2, 4 weeks after repair, gross, adhesion and histopathological observations of the repair part were performed.RESULTS AND CONCLUSION: Gross observation: in the control group, omental adhesion was found at 2 weeks after repair; and at 4 weeks after repair, the mesh was thickened and exhibited clear boundaries with the surrounding tissue, but common color and integration. In the experimental group, there was mild adhesion between the scaffold and the defect site at 2 weeks after repair, and the mesh was thickened, but the wound healed well with no prominence, swelling, and infection at 4 weeks after repair. Kadata adhesion score in the experimental group was lower than that the control group at 4 weeks after repair (P < 0.05). Pathological observation showed that at 4 weeks after repair, there were a large number of infiltrated inflammatory cells, capillary growth, and a large number of fibroblasts at the defect site in the control group; and meanwhile, a small amount of infiltrated inflammatory cell infiltration and a large number of collagen fibers and capillaries, with better granulation tissue maturity,were found in the experimental group. To conclude, the highly simulated chitosan scaffold can promote the repair of abdominal wall defects and reduce inflammatory reactions.

9.Ethical and Legal Issues Involved in Paternity Testing
Chinese Medical Ethics 1994;0(06):-
Paternity testing has to be cautiously practiced,since it involves issues coming from all aspects including ethics,legislation,family and society.If the educational backgrounds of the litigants prevent them from fully understanding the ethical and legal issues involved in paternal testing,it would thus be impossible to achieve a real "informed consent" for the litigants.It is our point of view that in these cases,and when no alternative solutions are available,it is the responsibility of those who perform paternity testing to advise the litigants give up the application for paternity test.Besides,it is time for judicial departments to place on the agenda the establishing of a technique standard for paternity testing and relevant judicial procedures,in order to protect the basic rights of informal consent and autonomy of litigants in paternity testing practices.It is in this article that some ethical and legal issues commonly involved in paternity testing are discussed.

Chinese Journal of Orthopaedic Trauma 2002;0(01):-
Impacted femoral neck fractures should be treated operatively as displaced fracture. Many authors suggested emergency operation. The principle of treatment of femoral neck fractures is anatomic reduction, fragmental compression,and rigid fixation. Closed reduction must be done in most cases. When close anatomic reduction can not be achieved, open reduction should be considered.Implants used recently consist of pins , screws,hook pins and gliding screws with side plate. Every implant has its own advantages, disadvantages and indications. The principle of treatment of femoral neck fractures in young patients is emergency operation (within 12h after trauma), anatomic reduction (open reduction when necessary), and rigid fixation with screws. Some authors stated the necessity of anterior capsularoctomy.
