OBJECTIVE:To evaluate the effect of temozolomide(TMZ)in combination with dexamethasone(DXM)on the proliferation of human gliocytoma U251 cells in vitro.METHODS:Human U251 cells were assigned to 1 of the 3 groups: TMZ(10,25,50,100,200,400?mol?L~(-1),respectively)alone or in combination with 40?mol?L~(-1)DXM(TMZ+DXM group)or control group(none drug).After treatment for 72 hours,the cell morphology,cell inhibition ratio,cell cycle and the apoptotic rate were detected.RESULTS:When TMZ concentration was greater than 100?mol?L~(-1)the cell inhibition ratio was higher in TMZ-treated group than in TMZ+DXM-treated group(P

The event of “diagnosing mental disorder but actually not” violates patients′right of informed con-sent and refused to health , showing some problems of “diagnosing mental disorder but actually not” and mandatory admission process and psychiatric judicial authentication , and also have some ethical problems .Therefore, relevant departments should perfect the laws and regulation , establish a hospitalized psychiatric patients appeal , the appeal channels , at the same time , physicians should follow a correct understanding , respect patients rights , disinterest-ed, the ethical principles of self -supervision and also use constraints should be regulated .

With Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) for instance, the three acupoints used to treat shoulder bi syndrome by needle knife, and through traceability and researching constant structure, the acupoint position, insertion trace, manipulation and clinical significance of needle knife medicine were discussed. Accurate position is one of the characteristics of acupoints selection of needle knife medicine. As for the acupoints selection method, the mean of body surface localization is always used. The phanerous or palpable bone processes, muscles and tendons are taken as positioning marks; pressing areas where appear sour, numb, or distensible and other sensations is considered as the principle of press positioning. So acupoints position method is the combination of observation and palpation. Different insertion methods can effectively relieve the accretive bursae synovialis, tendon, joint capsule and the compressed nerve, so that shoulder bi syndrome is relieved.

Objective To investigate and to compare the clinical curative efficacies of local anaesthesia and epidural block anaesthesia in tension-free hemioplasties. Methods 89 patients hospitalized were randomly divided in-to two groups, with each of them respectively adopting the two types of anaesthesia methods (local anaesthesia and epidural anaesthesia) to cure inguinal hernia,operation methods is tension-free hernioplasties. Results The results show that in terms of duration of operation, early-phase activities after operation, time of hospitalization, post-opera-tion pains,early-phase complication after operation and treatment expenses etc, local anaesthesia is undoubtedly supe-rior to epidural block anaesthesia. Conclusion Tensioa-free hernioplasties under local anaesthesia is worth clinical promotion to benefit all the patients.

Objective To observe the biomechanics of the anterior and posterior interosseous talo-calcaneal ligaments (ITCLs) . Methods Load-displacement characteristics of the subtalar joint were studied in 12 cadaver specimens whose ankle joints were mutilated. The ankle articular surfaces of the talus and the post-calcaneus were exposed. Bone blocks were then embedded in polymethylmethacrylate. The an-terior ITCLs were abscised in 6 of them, and the posterior ITCLs in the other 6. A multi-functional biome-chanical machine was used to perform the biomechanical tests on the specimens. Results When the anterior ITCLs were cut, the tali moved to the anterior-lateral side. When the posterior ITCLs were cut, the tali mostly moved to the anterior-interior side. Conclusions The anterior and posterior ITCLs have dif-ferent roles in maintaining stability of the subtalar joint. Since the posterior ITCLs seem more important than the anterior ones, they should have priority in ITCL reconstruction.

BACKGROUND:Simple medication therapy can not promote the healing of articular cartilage defects effectively;the insufficient sources of autogenous cartilage also limited cartilage transDlantation.OBJECTIVE:The types of articular cartilage injury and local micro-environment changes were analyzed to summarize the progress of tissue engineered seed cell transplantation and cell transplantation therapy for repairing articular cartilage injury.METHODS:The databases of PubMed database(http://www.ncbi.nlm.nih.gov/sites/entrez/)and CNKI(http://www.cnki.net/)were retrieved with the key words of"Tissue engineering,cell transplantation,articular cartilage defects",and the literature was limited to English and Chinese languages.Studies concerning articular cartilage injury or was closely related to tissue engineered seed cells transplantatiOn were included.Repetitive studies were excluded Survival and migration of seed cells,as well as the recovery of joint function and adverse reactions were served as evaluation index.RESULTS AND CONCLUSION:A total of 201 literatures were seized by computers,according to the inclusion criteria,papers concerning tissue engineering cells for repairing articular cartilage injury were analyzed.Clinically,articular cartilage damage was commonly resulted by traumatic arthritis,which is difficult to repair due to the poor self-repair capacity of articular cartilage.The emergence of tissue engineered cell transplantation brought new hope for articular cartilage injury healing Cell transplantation has obtained good effects in articular cartilage repair,but the technology is still room for improvement.How to technically improve the tissue-engineered 3 elements,namely,cells,scaffold materials,and biological activity factors were the research focuses.Autologous cartilage regeneration was the theoretical support for articular cartilage defects repairing,which needs to optimize its regeneration and to maintain a more stable chondrocyte phenotype in further research The tissue-engineered cells had received good effects in repairing articular cartilage injury,and it is expected to be a new clinical treatment for articular cartilage injury with the in-depth study of tissue engineering.
