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.

Objective To investigate the emergency treatment measures of spontaneous frontotemporal intracerebral hematoma.Methods Retrospectively analyzed the rescue process and surgical experiences of 27 patients with spontaneous frontotemporal intracerebral hematoma combined with subarachnoid hemorrhage or ventricular hemorrhage.Twenty-three cases underwent surgery;4 cases with cerebral hernia under general anesthesia underwent craniotomy hematoma clearance,aneurysm clip and decompressive craniectomy;7 cases with previous history of hypertension,considered with hypertensive intracerebral hemorrhage,was performed with craniotomy hematoma clearance and decompressive craniectomy in the emergency under general anesthesia; 12 cases of middle cerebral artery aneurysms bleeding,chosen craniotomy hematoma clearance and aneurysm clip;4 cases found nothing by digital subtraction angiography (DSA) or CT angiography (CTA),were given conservative treatment,one of them was found arteriovenous malformations after 1 month,which was treated by γ-ray.Results After the surgery,2 cases died due to severe cerebral infarction,25 cases were followed up for 6 months,according to the Glasgow outcome scale(GOS) classification:17 cases with good prognosis,7 cases with poor prognosis,1 case with vegetative state.Conclusions Cerebral hernia formation in patients with spontaneous frontotemporal intracerebral hematoma should relieve cerebral hernia and mass effect as soon as possible,early surgery to save lives.Which of them without brain hernia,after diagnosis by CTA or DSA,choice suitable treatment.Sufficient preoperative evaluation,suitable surgical timing and good microsurgical techniques can improve the prognosis.

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 pathogens,clinical characteristic and therapeutic method of acute kidney injury(AKI) Methods The morbidity,composition of pathogeny,staging and prognosis of 624 cases with AKI recruited by our department from January 1999 to December 2009,to evaluate the impacts of possible predisposing factors.Results The mortality rate of AKI was 19.6％(122/624),The mortality in the staging of exhaustion,damage,risk were 37.8％,33.4％ and 6.7％,respectively.Of the 624 patients there were 21 cases (3.4％) discharged due to exacerbation,29 cases (4.7％) maintained the status quo,and 452 cases (72.4％) cured or improved;Among 138 patients with blood purification there vere 116 cascs(84.1 ％)cured or improved and 22 cases (90.9％) with long term blood purification cured or improved.The pathogenyof the non-elderly group (＜60 years old)were original diseases and collapse,and the pathogeny of the elderly group (≥60 years old)were original diseases.Conclusions AKI is serious with high incidence and mortality in hospitalized patients.The efficacy of long-term blood purification is better than common treatment.Early prevention,early diagnosis and active intervention will help to increase survival rate of AKI aud improve prognosis.

MicroRNAs (miRNAs) are a group of small (about 22 nucleotides),endogenous,noncoding RNAs that direct mRNA degradation and translational inhibition post-transcriptionally by binding to complementary sequences in the 3' untranslated regions of specific target mRNAs.miRNAs play multiple important roles in the intestinal epithelium,influencing a number of intestinal disease processes.This review summarizes the regulatory roles of miRNA in intestinal epithelial differentiation,architecture,membrane permeability,immunological function,and more importantly,the intestinal mucosal barrier dysfunction-associated diseases.

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.
