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

Objective To study the pharmacodynamics features of cisatracurium besylate in differ-ent age patients. Methods One hundred and eighty patients were randomized to group Ⅰ (50-60 years old),group Ⅱ (61-70 years old)and group Ⅲ (above 70 years old).Each group was subdivided according to the dose of cisatracurium besylate, 0.10 mg/kg (2ED95)or 0.15 mg/kg (3ED95) into group Ⅰ2, Ⅰ3, Ⅱ2, Ⅱ3,Ⅲ2, Ⅲ3(n = 30).ECG, SpO2, PETCO2, HR and neuromuscular blockade were monitored. Intubation conditions were assessed when T1 was zero after cisatracurium besylate administer ration using a 4-part scale.The onset time, TOF no reaction time, duration time, recovery lime and hemodynamic response time were recorded. Re-sults The onset times of group Ⅰ3, Ⅱ3 and Ⅲ3 were significantly shorter than those of group Ⅰ2, Ⅱ2 and Ⅲ2 (P < 0.05).The percentages of patients with excellent intubation condition in group Ⅰ3, Ⅱ3 and Ⅲ3 were 93%, 90%, and 80%, which were markedly higher than those in group Ⅰ2, Ⅱ2 and Ⅲ2 (67%, 60%, 60%). TOF no reaction time and duration time were longer in group Ⅰ3, Ⅱ3 and Ⅲ3 than those in group Ⅰ2, Ⅱ2 and Ⅲ2. There was no significant difference in muscle chalasis among the six groups. Conclusions Cisatracuri-um besylate 0.15 mg/kg produces quicker onset time and acceptable intubation conditions in the different age patients than 0.10 mg/kg. Recovery time is independent on the dosage and age. Aging has no influence on the phannacodynamics of single injection of cisatracurium besylate.

Splenic radiofrequency ablation (RFA) is a safe, effective and minimally-invasive approach for the management of hypersplenism due to portal hypertension. After RFA, the remnant volume of the spleen will be decreased, the hypersplenism can be corrected, and the hepatic artery blood flow can be significantly increased with resultant marked improvement of liver function; in addition, hypertrophy and regeneration of the liver can be induced. However, many factors can affect the therapeutic results of RFA,therefore, further studies are necessary to clarify the underlying mechanisms.

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.

ObjectiveTo explore the application value and techniques of vaginal hysterectomy of non-prolapsed uterus lesion in primary hospital. Methods140 cases who suffered from uterine fibroid without adhesion,glandular fibroids,functional bleeding without uterine prolapse and malignant disease were selected and divided into observation group(80 cases with vaginal hysterectomy)and control group(60 cases with routine abdominal hysterectomy).Then the clinical treatment effect was analyzed. ResultsCompared with control group,peri-operative bleeding (150 ±23)ml vs(243 ±41)ml,operation time(65 ± 14.0)min vs(90 ± 27.0)min,body temperature recovery time (3 ±0.5)d vs(4 ±0.8)d,anus exhaust time(14 ± 1.8)h vs(26 ±2.7)h,the length of time(5 ±0.8)d vs(11 ±2.9)d in observation group were all reduced,differences were significant(all P＜0.01)and no case was transferred to opening appendectomy. ConclusionFor these disease including uterine fibroids with no adhesion,glandular fibroid uterine bleeding,the vaginal hysterectomy was safe and feasible,and had the advantage of smaller trauma,less bleeding,shorter hospitalization time,faster recovery etc.It was worthy to be popularized in primary hospital.

Health management is the intrinsic requirement to build and embody a harmonious society. While health management provides strong human resources for the development of a harmonious society, a harmonious society promotes the health management. Health management plays a significant role in the construction and development of a harmonious society in terms of reducing risks to the health, improving the quality of life, lowering medical cost, lightening the socio-medical burden, enhancing awareness of health, improving the national health conditions, protecting health resources, and promoting a sustainable social development. Health is an important component of social productive forces, and health management is an essential prerequisite for the harmonious development of society. There would be no real harmonious society without effective health management.

BACKGROUND: As demonstrated by recent reports, immediate early genes (IEGs) are rapidly induced and expressed when a songbird is stimulated either by bird-song or by its vocal-behavior. The expression area and level of IEGs in the brain, such as zenk, c-fos and c-jun, are corresponding to where and how the neurons are related as a songbird is stimulated, suggesting that IEGs play important roles in vocal learning and memory.OBJECTIVE: To study the relation between vocal learning of songbird and immediate early gene so as to understand the mechanism of human language and the control of central nervous system.DATA SOURCES: All papers were cited from MEDLINE with the keywords of "songbird, vocal learning, memory, zenk, c-fos and c-jun" in English between January 1990 and December 2001. Meanwhile, we searched the Chinese journals full-text database and Wanfang database with the same keywords in Chinese between January 1990 and November 2001 were also searched.STUDY SELECTION: The papers about immediate early genes and vocal learning and memory in songbirds were selected. Then non-randomly controlled studies were excluded, and the rest full-text papers were looked up.DATA EXTRACTION: Totally 17 papers about immediate early genes and vocal learning and memory in songbirds were found. We choose 11 papers in them and 6 was excluded because of summarization.DATA SYNTHESIS: ① zenk and vocal behavior: Expression of zenk in bird's brain can affect learning and memory through adjusting synthesis of special protein. ② Reaction of c-fos to various songs: The reaction of local neurons in bird's brain to the birdsongs are made by the decision of the numbers of song factor in learning songs. ③ Associations of c-jun and cfos: zenk, fos and jun are the necessaries for maintaining long-term memory, which produce a marked effect through signal transduction, reconstruction, synthesis and transduction of induced synapse.CONCLUSION: Immediate early genes (IEGs) are rapidly induced and expressed when a songbird is stimulated either by bird-song or by its vocal-behavior. The expression area and level of IEGs in the brain, such as zenk, c-fos and c-jun, are corresponding to where and how the neurons are related as a songbird is stimulated, suggesting that IEGs play important roles in vocal learning and memory.
