By analyzing the scope and demands of mental health service in general hospitals, the authors point out that at present domestic general hospitals are confronted with such problems as insufficiency of resources for mental health service, low recognition rate of dysphrenia, and lack of systematic consultations and liaison in psychiatric work. Then they put forward a number of measures for improving mental health service in general hospitals: ①establishing a department of psychiatry in each general hospital; ②widely conducting consultations so as to maintain a strong liaisom in psychiatric work; ③genuinely achieving the transformation of the medical mode; ④strengthening education in psychological medicine and the spread of popular science so as to broaden the channel and coverage of mental health service and meet the needs of reform and development of the health cause in the contemporary era.

Aim To investigate whether the polypeptide from Chlamys farreri(PCF)protected HaCaT cells from UVB-induced apoptosis through Fas-caspase-3 and ROS-cytochrome C.Methods Experiment designs were divided into five groups:control group,UVB model group,UVB+5.69 mmol?L-1PCF group,UVB+2.84 mmol?L-1 PCF group,UVB+1.42 mmol?L-1 PCF group.SiRNA for Fas inhibited Fas expression of UVB-induced HaCaT cells.Using agarose gel electrophoresis,the effects of Fas siRNA and ROS scavenger NAC on UVB-induced apoptosis of HaCaT cells were investigated.Expression levels of cytochrome C andcaspase-3 after inhibitory Fas were determined by Western blot analysis.Intracellular ROS was detected by means of an oxidation-sensitive fluorescent probe(DCFH-DA).Results SiRNA for Fas had inhibitory effects on UVB-induced apoptosis of HaCaT cells and caspase-3 expression.NAC had inhibitory effects on UVB-induced apoptosis of HaCaT cells.PCF inhibited UVB-induced generation of ROS and cytochrome C release dose-dependently.Conclusions PCF protected HaCaT cells from UVB-induced apoptosis.Its inhibitory effect on apoptosis could be attributed to inhibition of Fas-caspase-3 and ROS-cytochrome C pathways.

Objective To explore the efficiency of postoperative individualized chemotherapy based on genetic testing results for non-small cell lung cancer (NSCLC). Methods Fifty-six NSCLC patients at stageⅡorⅢA who accepted video-assisted thoracic operation were divided into two groups:the individualized chemotherapy group (n=26) and non individual?ized chemotherapy group (n=30). The fresh lung tumor tissue of individualized chemotherapy group was tested target gene,in?cluding excision repair cross complementing 1 (ERCC1),ribonucleotide reductase subunit M1 (RRM1),β-tubulinⅢ,thymi?dylate synthase(TS),epidermal growth factor receptor (EGFR) and breast cancer gene 1 (BRCA1). The theraputic plan was based on genetic testing results in individualized chemotherapy group, and the non individualized chemotherapy group re?ceiving gemcitabine plus cisplatin. The 1-year disease free survival (DFS), 2-year disease free survival (DFS), the progres?sion-free survival (PFS) and the overall survival (OS) were compared between two groups. Results The 2-year DFS (57.69%), PFS (22.1 ± 5.0 months) and OS (24.1 ± 3.2 months) were significantly higher in the individualized chemotherapy group than those of non individualized chemotherapy group (respectively 30.00%, 18.9 ± 6.2 months, 21.9 ± 4.3 months, P<0.05). There was no significant difference in 1-year DFS between two groups (88.46%vs 83.33%, P<0.05). Conclusion The individualized chemotherapy based on genetic testing results can enhance the 2-year DFS, PFS, OS and the efficiency of postoperative adjuvant chemotherapy for NSCLC.

Objective To develop a rapid screening method of environmental estrogen in vitro. Methods Estrogen responsive element (ERE) was inserted into the upstream of Lac Z (?-galactosidase ) reporter gene and the reporter gene was regulated under estrogen receptor(ER) in the recombinant yeast cells by the molecular biological technique. When the yeast cells was affected by environmental estrogen, conformational change of ER lead to expression through binding to ERE. There exist the functional relationships between the expression and the pollution degree of environmental estrogen. Therefore, the pollution degree can be reflected by assaying the activity of ?-galactosidase. Results It was identified by PCR that recombinant yeast cell, whose Lac Z reporter gene regulated under estrogen receptor, was successfully reconstructed. The experimental results showed that the time-dose-effect response had no significant changes when the recombinant yeast cell bad been exposed to ?-estradiol for 4 and 8 hours respectively; among the three methods of yeast disintegration, the ultrasonic vibration method had more advantage compared with that of the other methods and this dose-effect curve exhibited "S" shape; among 3 test chemical products, ?-estradiol was the most estrogenic activity, biosphenol A take second place, estradiol benzoate was the lowest. Conclusion The assay system of yeast cell for environmental estrogen hormone mediated by estrogen receptor is stable and applicable.

Objective To assess quickly the potential environmental pollution by using the luciferase transgenic cells. Methods Many electrophile compounds in the environment can generate oxidative stress,so that the transcription of certain protective genes is induced via specific DNA motifs called electrophile response elements (EPREs). We have made a vector containing a single EPRE fused to the TK minimal promoter and the gene encoding firefly luciferase (EPRE-LUC) by adopting bio-molecular techniques. From this vector the stable LUC expression vector regulated by EPRE had been successfully reconstructed. This reporter construct was transfected into HeLa cells,and the clones resistant to G418 were selected. The resistant cells were treated by the different concentrations of sodium arsenate(NaAsO2),cadmium chloride (CdCl2),mercury chloride(HgCl2) and diethyl mateate (DEM). After that,the expression of luciferase was determined by luciferase assay kit. Results The correct construct frame of LUC reporter vector regulated by EPRE was identified by DNA sequencing; the dose-dependent relationships between the LUC expression and the test substance concentration were found. Among them,the relationship produced by DEM was the most significant. Conclusion The LUC transgenic cells regulated by EPRE have been successfully constructed.

Objective 　To explore the relationship between psychosocial factors and risk of vascular dementia. Methods　A cohort study of people 55 years old and over were followed up 10 years after a baseline screening. 5055 older subjects in Shanghai were stratified and cluster sampled from community. Information about psychosocial factors was collected during the baseline screening with an interview in 1987. The clinical diagnosis of dementia and vascular dementia (VD) were made according to DSM-Ⅲ-R and Hachinski Ischemic Score (HIS). In 1997,the elders who were not having dementia in 1987 were surveyed; Clinical diagnosis terms of that was made in above mentioned criteria. Then we analyzed the relationship between the psychosocial factors and VD in community elderly population by means of Logistic regression and estimated the incidence of VD.Results　1203 subjects were re-surveyed in 1997 and among them 124 new cases of dementia including 36 cases of VD were identified. By calculating the relative risk (RR) of psychosocial factors to the VD, we found that several psychosocial factors were correlated with the VD including not taking group activities, unsatisfying life, negative life events and depression (RR＞1). ADL total score are also good predictive points for VD.Conclusions　Psychosocial factor may play an important role in the vascular dementia developed.
