Objective To explore the relationship between job burnout feeling and sleep quality in psychiatric female medical staff.Methods 100 female medical staff were randomly selected from two mental hospitals in Wenzhou,and the Pittsburgh sleep quality index was used to evaluate and Maslach burnout inventory;and the relation-ship between sleep quality and job burnout was analyzed.Results Female psychiatric and medical personnel to the personality dimension score was (10.84 ±4.75)points,which was higher than Maslach norm (7.12 ±5.22)points;emotion exhaustion scores of (14.44 ±6.38)points,low achievement sense score of (15.07 ±6.89)points,below the Maslach often die emotion exhaustion scores of (22.19 ±9.53)points and low achievement sense scores (36.54 ± 7.34)points.The differences were statistically significant (t =-12.15,7.84,-31.15,all P <0.01).Job burnout and there were significant correlations between sleep quality and the emotional exhaustion and personification and PQSI seven dimensions and the total score was a positive correlation,low sense of achievement and PQSI total score and negatively correlated with seven dimensions.Conclusion Wenzhou psychiatric female medical staff burnout is significantly higher than the general population,there is a correlation between staff burnout and sleep quality,and the more serious burnout,poorer quality of sleep.Improving the quality of sleep of medical staff is one of the ways to relieve job burnout.

OBJECTIVE: To optimize the process for extraction and purification of Schisandrin in Fructus Schisandra Chinensis. METHODS: The orthogonal test L9( 34) was adopted to optimize the water extraction process using Schisandrin and its extracts as indicators. The parallel test was used to optimize the parameters of the alcohol precipitation technique. RESULTS: The optimized process for extraction and purification of Schisandrin was as follows: extracting three times using 10- fold water, 1. 5h each time, with filter liquids concentrated to 1. 4g of crude drug mL- 1 then precipitated to 80% ; filtering alcohol liquids, and adjusting pH value to 7. CONCLUSIONS: This method can be used as a reference for the extraction of Fructus Schisandra Chinensis.

Objective To investigate efficiency and distribution of gene delivery to the injured tendons by microinjeetion and tissue reactions caused by different vectors. Methods By using a mi-croinjection technique, 10μl of pCMV-EGFP, pCAGGS-EGFP, AAV2-EGFP and Ad5-EGFP harboring enhanced green fluorescence protein (EGFP) gene were respectively injected to two sites of the proximal stump of 48 transected digital flexor tendons in 18 chickens. At days 3, 7, 14 and 21, the tendons wereharvested for observing distribution and expression of EGFP under a fluorescence microscope by using fro-zen tissue sections. The tendon sections were also stained with hematoxylin and eosin to examine inflam-mation caused by these vectors. The other 24 normal flexor tendons were served as controls. ResultsCompared with normal tendon tissues, the EGFP expression was observed in tendons at days 3, 7, 14 and21 after injection. The EGFP expression was observed at day 3 and reached peak at day 7 for all vectors.The EGFP expression was decreased at day 14 but seldom seen at day 21. EGFP was distributed evenly inthe injected tendon segment adjacent to the cut level. The EGFP expression in the tendons injected withAAV2-EGFP and Ad5-EGFP was higher than that with pCMV-EGFP and pCAGGS-EGFP injection, withinsignificant statistical difference upon the EGFP expression between AAV2-EGFP and Ads-EGFP vec-tors. Tissue reactions of the tendons caused by the liposome-plasmid vector ( including pCMV-EGFP and pCAGGS-EGFP) were the most prominent among all vectors. Infiltration of inflammatory cells, chiefly lymphocytes and neutrophilic granulocytes, were found. The tendons injected with AAV2 vectors presen-ted gentle inflammatory reactions. Conclusions Mieroinjection to two sites of each tendon stump deliv-ers the transgene to the entire tendon segment adjacent to the cut. Gene delivery by the AAV2 and Ad5 vectors has the highest cfficiency among four vectors tested, when expression level peaks at day 7 after in-jection and AAV2 vector causes the slightest tissue reactions in the tendons, indicating that the AAV2 vector is a promising gene delivery vector and microinjection is practical for tendon gene therapy.

Tort Liability Law set tougher requirements on the validity and authenticity of medical records,featuring explicit protection of patient rights of informed consent.Based on the changes in the law since its enforcement,the authors studied existing deficiencies of electronic medical records and came up with the following suggestions.Establish sound legal accreditation system for electronic medical records; perfect related laws and regulations to ensure standard application of the electronic medical records; and work out regulations to make medical staff aware of their legal responsibilities when applying electronic medical records.These recommendations will enable electronic medical records better fit the current legal environment onto the track of healthier development.

Objective To compare the efficacy and the side-effect of three different ways in treating the patients with malignant pleural effusion. Methods 98 patients histologically proved malignant pleural effusion were randomly divided into three groups, bleomycin group(BLM), bleomycin with mycobacterium group( BLM + UTL) and blemycin with intertleukino2 ( BLM +IL). 31 patients were treated with bleomycin intrapleural injection in BLM group,32 patients were treated with bleomycin and Utilin's(mycobacterium) intrapleural injection in BLM + ULL group and 35 patients were treated with bleomycin and intertleukin-2 intrapleural injection in BLM + IL group. The therapeutic efficacy, change of performance and side effects were compared among the three groups after one period of treatment. The changes of CEA and TNF in the pleural effusion were examined before and after treatment. Results The therapeutic efficacy and performance improvement were higher in BLM+UTL and BLM+IL group than that of BLM group(P＜0. 05) ,the pleural CEA of post-treatment in three groups were lower than that of pre-treatment(P＜0.01) ,the CEA after treatment in BLM+UTL group and BLM+IL group was lower than that of BLM group(P＜0. 01,respectively). The pleural TNF of post-treatment in BLM+UTL and BLM+IL groups was higher than that of pre-treatment(P＜0. 01 ) in BLM group. The pleural TNF of post-treatment in BLM+UTL and BLM+IL group was higher than that of BLM group ( P＜0. 01 ). Conclusion Intrapleural injection of mycobacterium with bleomycin or interlekin-2 with bleomycin has better efficacy than using bleomycin only in treating malignant pleural effusion.
