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 .

Poly ADP-ribose polymerase(PARP)inhibitor is a targeted biological agent for the treatment of ovarian cancer, which is mainly suitable for platinum-sensitive ovarian cancer patients. However, data from clinical trials showed that PARP inhibitors have certain therapeutic effect on platinum-resistant or platinum-refractory ovarian cancer patients. It may become a new hope for treatment of ovarian cancer patients in the future.

Forty-two hyperthyroid patients with mild hepatic dysfunction were treated with 131I once orally and followed up for 6 months. The changes of hepatic functions (ALT, AST, ALP, A/G) were determined before and after treatment, hepatic function was ameliorated in these patients. The results indicate that 131I-iodine is safe and effective in treating hyperthyroidism with mild hepatic dysfunction.

Systemic insulin resistance has been well known. Recently, an important question has been raised regarding whether islet cells are resistant to insulin (insulin resistance of ?, ? and ? cells) due to the discovery of insulin receptor and its downstream insulin signaling pathways in islet cells. As a new study field of insulin resistance, the elucidation to this issue is crucial for the new insight into the mechanisms of insulin resistance per se and type 2 diabetes.

The article mainly introduced development status of care robots for the older in the domestic and overseas, stated functions of care robots for the aged, listed problems of care robots for the older and put forward solutions. In addition, the article illustrated future development.
