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.

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.

Objective To explore the anti-inflammatory mechanisms of purslane by evaluating its effects on the expression of tumor necrosis factor-α (TNF-α) and intercellular adhesion molecule 1 (ICAM-1).Methods A model of inflammation was developed in 45 mice by painting xylene to the auricle of the right ears,which were then divided into 3 groups to receive no treatment (negative control group),be topically treated with the extraction of purslane from South Korea (positive control group) or Yunnan province (experimental group).Fifteen mice receiving no sensitization nor treatment served as the blank control group.Two hours after the single topical treatment,skin tissue samples were obtained from the site of experimental inflammation and subjected to pathological examination by using hematoxylin and eosin (HE) staining.Immunohistochemistry was performed to quantify the expression of TNF-α and ICAM-1 in the tissue samples.Results Pathological examination showed blood vessels and a small quantity of lymphocytes in murine dermis of the blank control group as well as loose and edematous dermis infiltrated with massive lymphocytes in the negative control group.However,there was only mild edema and perivascular infiltration with some inflammatory cells in the dermis of the positive control group and experimental group.Neither TNF-α nor ICAM-1 was expressed in the skin tissue of the blank control group,but an intense expression was observed for TNF-α in the vascular endothelial cell membrane and for ICAM-1 in the vascular endothelial cell membrane and lymphocyte membrane in the negative control group,which was significantly downregulated by the purslane from South Korea in the positive control group and by the purslane from Yunnan province in the experimental group (all P ＜ 0.01).Rank sum test showed a statistical difference in the expression level of TNF-α and ICAM-1 between the blank control group and experimental group (both P ＜0.01).Conclusion The purslane from Yunnan province may counteract inflammation by affecting the expression of TNF-α and ICAM-1.

Objective To investigate the effects of urinastatin on the production of inflammatory mediators and cytokines of acute pancreatitis(AP), and the effect of treating AP with urinastatin. Methods Serum levels of tumor necrotic factor ?(TNF ?), nitrogen oxide(NO), oxygen free radicals and amylase were determined in AP rats and patients with AP respectively. Effects of urinastatin treatment on the alleration of symptoms, signs and of pancreas in patients with AP were also examined. Results Urinastatin could apparently decrease the serum levels of TNF-?, oxygen free radicals and amylase in AP rats and the patients with AP, also alleviate the symptoms and signs of the patients with AP, and the effective rate of treating AP with urinastatin reached 90 percent. Conclusions Urinastatin, which can inhibit the production of inflammatory mediators and cytokines in AP, is an effective and cheap drug for AP.

Objective To search for a way of treating chi1dren's idtopathic nephrotic syndrome (INS) hypoadrenocorticismand its significance. Meethods Thirty-nine patients (31 males and 8 females) with INS were randomly divided into twogroups: 21 patients in tera-peutic group (treated by prednisone, astragali and acanthopanax root) and 18patients in control group (Simply treated by prednisone). 1ml blood was respectively drawn from all thepatients at 8 o'clock (one time before treatment and one time after treatment), the serum cortisol wasdetermined by radioimmunoassay (RIA). Results In control group, the levels of serum cortisol still remained lower than the normal value aftertreatment and the levels after large dosages prednisone treatment were markedly lower than that beforetrea-tment. The values of serum cortisol returned to be normal after treatment in therapeutic group. Conclusion Astragali and acanthopanax root can restore the hypoadrenocorticism in children with INS.

Objective To create a further understanding of the angiographic features of the carotid artery pseudoaneurysm (CAPA) and to explore the clinical diagnostic value of angiography.Methods Sixteen cases of CAPA with clinical and angiographic data were analyzed retrospectively. The angiographic appearances in all of the patients were observed dynamically and precisely with a double blind method by two experienced radiologists together and formed a consensus interpretation. Results Angiography provided a definite diagnosis for all cases. The parent arteries included the common carotid artery (1 case), common carotid artery bifurcation (9 cases), internal carotid artery (5 cases) and external carotid artery (1 case). The angiographic features of the CAPA were: All cases showed the contrast media retension in the aneuysms; turblulent flow within aneurysm in 9 cases; the “jetting sign” at the leak of the parent artery in 7 cases; increase angulation of the bifurcation of internal and external carotid arteries in 12 cases.Conclusions Angiography is the most valuable examination method in diagnosis of CAPA, and it can not only provide definite diagnosis, but also play an important role in selection of therapeutic plan.
