BACKGROUND: Impoverished undergraduate is a new and special group appearing under the market economy. Strengthening depth and extent is necessary to probe into and study it.OBJECTIVE: To investigate the social support of impoverished undergraduates and probe into its effect on mental health of impoverished undergraduates.DESIGN: Cross-section survey, clustering stratified sampling SETTING: College of Education of Jiangxi Normal University PARTICIPANTS: Totally 445 impoverished undergraduates of Jiangxi Normal University, Nanchang University, Jiangxi Medical College, East China Jiaotong University and so on of nanchang city were recruited in October 2002. All the participants were volunteers.METHODS: Social Support Rating Scale (SSRS) was used to evaluate the social support of impoverished undergraduates. The scale is composed of 10 items including objective support, subjective support, and utilization degree of support. Symptom Checklist 90 (SCL-90) was used to evaluate the mental health status of impoverished undergraduates. SCL-90 has 90 tests, using 1 to 5 degree to score( from not present to severe), including somatization, obsessive compulsive, interpersonal sensitivity, depression,anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism (9 factors). During the process of investigation, the testee was tested singly in 2 hours without interference and influence of others. The questionnaires were taken back and the authenticity and validity of the questionnaires was verified.RESULTS: All the 500 questionnaires handed out were taken back. Totally 445 pieces of effective questionnaires were involved in the analysis with the effective rate of 89%. ① There was significant difference in objective support and utilization degree of the support between the impoverished undergraduate of either gender (P ＜ 0.01 or P ＜ 0.05); ②There were significant differences in subjective support and utilization degree of support between only-child and non-only-child (P ＜ 0.01 or P ＜ 0.05);③ There was significant difference in utilization degree of the support between impoverished undergraduates from city and impoverished undergraduates from country(P ＜ 0.01 or P ＜ 0.05 );④Obvious correlation existed between mental health and social support of the impoverished undergraduates;⑤Through regression analysis, it showed that social support had significant effect on the mental health of impoverished undergraduate (F= 12.770,P=0.000).CONCLUSION: Significant difference existed between different genders,only-child or non-only-child, impoverished undergraduates coming from urban area or rural area. Social support has significant effect on the mental health of impoverished undergraduates.

Objective To study and summarizes the methods ofthe standardized hospital infection manage -ment technology in order to prevent and control hospital infection scientifically .Methods Taking the chance of im-provingthe execution of the standardized hospital infection management issued by the Ministry of Health ,we realized organizational execution by enhancing the responsibility decomposition , mechanism implementation by standardized completion,ideological implementation by education and training ,the implementation of standards by inspection and monitoring and finally form a team by enhanced communication .Results The technicalstandards of hospital infection management was implemented and the quality of hospital infection control was improved progressively .Conclusion It is an effective way to guarantee medical security to improve the execution of the technical standard of hospital infec -tion management .

In recent years, translational medicine, which is characterized by advanced concepts and methods, developes rapidly and playes a strategic role in the development of TCM acupuncture and moxibustion. Therefore, it is worth studying by acupuncturists. Through the background, development, features and research model of translational medicine, the present situation and problems of TCM acupuncture research are analyzed. Several cases of translational Chinese medicine and acupuncture are listed with the consideration of the concept of translational medicine. Studies and thoughts on translational acupuncture are expounded as well. Thus, it is suggested that combined with characteristics of acupuncture, the concept of translational medicine should be utilized to instruct the clinical treatment and research of acupuncture, foster researchers of translational medicine as well as establish the related research teams.

OBJECTIVETo establish a RP-HPLC-PDA method for determination of five triterpenic acids (pomolic acid, hawthorn acid, corosolic acid, oleanolic acid and ursolic acid) in different parts of Salvia chinensis.

METHODThe isocratic elution and separation was achieved on a Kromasil C18 column (4.6 mm x 250 mm, 5 microm), using acetonitrile-water (90:10) as the mobile phase at a flow rate of 0.8 mL x min(-1). The detection wavelength and column temperature were set at 205 nm and 28 degrees C, respectively.

RESULTThe calibration curves of pomolic acid, hawthorn acid, corosolic acid, oleanolic acid and ursolic acid were linear over the ranges of 0.096 0-2.400, 0.1230-3.075, 0.2420-6.050, 0.2830-7.075 and 0.2730-6.825 microg (r = 0.9998, 0.9997, 0.9999, 0.9995, 0.9999), respectively. The average recoveries were 98.43%, 98.13%, 100.6%, 98.19% and 99.15%%, respectively, with RSD (n=6) being 1.3%, 0.67%, 1.2%, 0.87% and 0.43%.

CONCLUSIONThe proposed method is so simple and highly reproducible that it promises to be applicable for determination of major triterpenic acids in S. chinensis.
