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 .

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

Mesenchymal stem cells(MSCs) can directly act on tumor cells to inhibit their growth,and could also migrate to the tissue lesions and tumor tissues to transfer and express many kinds of anti-cancer factors.Numerous researches have applied MSCs as carriers of drugs to induce apoptosis,inhibit differentiation of tumor cells and inhibit tumor angiogenesis,and have got outstanding antitumor results.

Objective To evaluate the efficacy and safety of dexmedetomidine combined with propofol for gastroscopy in elderly patients.Methods Ninety ASA physical status Ⅰ-Ⅲ patients,aged 65-80 yr,weighing 45-80 kg,scheduled for elective gastroscopy,were randomized to receive either dexmedetomidine combined with propofol (group DP,n =45) or propofol (group P,n =45).In group DP,dexmedetomidine 0.4 μg/kg was infused over 5 min and propofol 1.0 mg/kg was injected intravenously 25 min later.Propofol 2.0 mg/kg was injected intravenously in group P.When body movement occurred during operation,additional propofol 0.2 mg/kg was given intermittently.Mean arterial pressure (MAP),heart rate (HR),pulse oxygen saturation (SpO2) and Narcotrend index were monitored during the whole procedures.The consumption of propofol and vasoactive agents,adverse cardiovascular events,and respiratory depression were recorded.Results Compared with group P,the consumption of propofol,incidences of respiratory depression and tachycardia,and degree of body movement were significantly decreased (P ＜ 0.05),Narcotrend index was increased during operation (P ＜ 0.01),and no significant change in the incidence of circulatory depression was found in group DP (P ＞ 0.05).Conclusion Small dose of dexmedetomidine 0.4 μg/kg combined with small dose of propofol 1.0 mg/kg provides good efficacy and safety for gastroscopy in elderly patients.

Objective To evaluate risk factors of restenosis of vertebral artery origin after stenting.Methods A total of 144 continuous cases were collected for this retrospective analysis.More than 50％ of stenosis in the original sites after treatment was defined as restenosis.Patients were divided into restenosis group (39 patients) and none-restenosis group (105 patients).The risk factors associated with restenosis were compared between the two groups by Chi-square test,including sex,age,presence of hypertension,diabetes,coronary heart disease,hyperlipidemia,smoking and drinking,the difference of preoperative neurological symptoms,combination with other vessels,stenosis,as well as stent type and stent size.Logistic regression was used to test the risk factors for restenosis.Results The incidence of restenosis of vertebral artery origin after stenting was 26.4％,and all of them occurred in 5 months.Between the two groups,there was no significant difference of distribution of sex (male 89,female 34,x2 =0.804,P =0.370),age(60 vs 21 patients of more than 60 years old,x2 =2.358,P =0.125),hypertension (67 vs 28 patients,x2 =0.253,P =0.615),diabetes (27 vs 9 patients,x2 =0.914,P =0.91),hyperlipidemia (6 vs 5 patients,x2 =0.478,P =0.489),coronary heart disease(32 vs 6 patients,x2 =2.489,P =0.115),smoking (50 vs 24 patients,x2 =0.129,P =0.719),drinking(20 vs 13 patients,x2 =0.001,P =0.978),diameter of stents (53 vs 18 patients of more than 4 mm,x2 =0.213,P =0.645),length of stents (45 vs 19 patients of more than 15 mm,x2 =0.927,P =0.336),preoperative neurological symptoms (93 vs 29 patients,x2 =0.250,P =0.617).There was significant difference of factors including combination with the bilateral stenosis (43 vs 24 patients,x2 =4.844,P =0.028),combination with the internal carotid artery stenosis(49 vs 26 patients,x2 =4.558,P =0.033) and stent types(59 vs 11 patients of drug eluting stent,x2 =8.916,P =0.003) between the two groups.Bare stents and combination with internal carotid artery stenosis were independent risk factors for restenosis by logistic regression.Conclusions The incidence of restenosis with vertebral artery origin occurs in 5 months after surgery.Bare stents and combination with internal carotid artery stenosis increased the incidence of restenosis,and preoperative neurological symptoms of vertebrobasilar system and presence of the bilateral stenosis may induce restenosis.

Objective To establish a method of solid phase extraction-reversed-phase high performance liquid chromatography(SPE-HPLC)for determination of methomyl in plasma of rat.Methods The sample pretreatment method,the test conditions,the linear range,the sensitivity,the specificity,the precision, the accuracy,the stability and the recoveries for plasma were investigated by using rat plasma spiked with standard methomyl and intemal standard substance.Results The linear range was 0.1～20μg/mL ( r= 0.9993,P<0.001).The limit of detection was 0.03μg/mL(S/N ≥3).The intra and inter-day precision of assay for methomyl was less than 8.33%and 11.11%in plasma respectively.The intra and inter-day accuracy of assay for methomyl was between 90%and 120%in plasma respectively.The recoveries for methomyl were more than 88%±4.4%in plasma.Conclusion The HPLC method for quantitative and qualitative analysis of methomyl is simple,rapid and accurate,which is suitable for the identification of methomyl in the cases.

Radioimmunotherapy using monoclonal antibodies incorporated with radionuclide has been showed to be an effective agent for refractory non-Hodgkin's lymphoma (NHL). Many anti-CD20 antibodies labeled with radionuclide, such as 90Y-ibritumomab tiuxetan (Zevalin) and 131I-tositumomab tiuxetan (Bexxar), have been reported to be effective for the treatment of patients with relapsed or refractory low-grade, follicular, or transformed NHL. This review summarizes the current advance in clinical trials and studies of Zevalin and Bexxar for the treatment of NHL patients.
