Objective To analyse the role of haptoglobin in the immunomodulatory in patients with premature coronary heart disease.Methods Clinical data of 60 premature coronary heart disease patients and 40 healthy people was analysed.The general information and serume haptoglobin,hs-CRP and IL-6 were compared.Results There were no statistically difference between the two groups of the general information such as sex,years,BMI,hypertension and diabetes (P>0.05),excepts the smoking history(27/33 vs 9/31,χ2=3.324,P<0.05).Hp,hs-CRP and IL-6 levels in the observer group were signifi-cantly higher than the control group,the difference was statistically significant (97.76±23.08 mg/L vs 65.81±19.42 mg/L,10.43±3.81 mg/L vs 3.05±0.94 mg/L,16.43±4.59 pg/L vs 4.62±1.83 pg/L,P<0.001).Correlation analysis showed that in the observer group Hp and hs-CRP showed a significant positive correlation (r=0.518,P<0.001),and the same results was found between IL-6 and Hp (r= 0.291,P=0.024).Conclusion Haptoglobin level was significantly in-creased in patients with coronary heart disease,which suggested that haptoglobin played a role in the development of coro-nary heart disease,and its level was correlated with IL-6.

Objective To study the impact of gender,gender role and gender traits on depression in adolescents.Methods A sample of 1330 middle school students from seven provinces in China completed Beck Depression Inventory (BDI) and Gender Traits Inventory.Results 27.1 percents of participants displayed the symptoms of depression.The mean score of males of BDI was 10.04 ± 8.38 while that of females was 10.33 ± 8.37,indicating that there was no sex differences in depression of adolescents(P=0.535).The participants could be classified into 4 sex role types:masculine,feminine,androgynous and undifferentiated,and the BDI mean score of each type was 9.51 ± 7.66,12.30 ± 8.81,9.14 ± 8.10,10.72 ± 8.66,and significant differences were found among adolescents with different gender roles (P =0.000).BDI scores of the feminine adolescents were the highest among the four gender roles,which were significantly higher than scores of the masculine and androgynous adolescents (P =0.000).Regression analysis indicated that adolescents with more positive masculine traits tended to be less depressive (t =-4.966,P ＜ 0.01) while adolescents with more negative masculine (t =2.574,P ＜ 0.01) or feminine (t =10.566,P ＜ 0.01)traits tended to be more depressive.Conclusion Gender role rather than gender has greater impacts on adolescent depression,and specifically,positive masculine traits represent protective factors for depression.

Objective To observe the effect of tai chi chuan on anneal dyspnea and endurance stamina of patients with chronic obstructive pulmonary disease (COPD).Methods 80 COPD patients were randomly divided into control group (n=40) and training group (n=40). The common therapy of two groups was the same; but the training group was added with Chen style tai chi chuan training for 30 minutes one day. At the same time, all patients were evaluated about the dyspnesa exponent before and after 3 months training.Results There were no significant differences in FEV1(%), FEV1/FVC(%),heart rate and breath frequency/minute before and after treatment (P>0.05) between two groups, but in dyspnea exponent, there was a significant difference between two groups (P<0.05).Conclusion Tai chi chuan training can reduce the symptom of COPD patients.

Objective To study the roles of regulated upon activation normal T cell expressed and secreted(RANTES) and monocyte cbemoattractant protein-1 (MCP-1) in human immunodeficien- cy virus-1(HIV 1) infected patients.Methods RANTES and MCP-1 in HIV-1 infected patients, including treated and untreated groups,and healthy control group were determined by enzyme-linked immunosorbent assay(ELISA).The recombinant plasmids,hMCP-pcDNA3.1,bRANTES- peDNA3.1 and hMCP/bRANTES-pcDNA3.1,were constructed and transfected into CHO cells to overexpress the corresponding recombinant proteins,whose chemoattract function was then studied. Results The level of RANTES was (164.3?21.3) pg/mL in healthy control group,(1 224.1?62.0) pg/mL in untreated group and (475.3?36.2) pg/mL in treated group.The level of MCP-1 was (90.6?28.5) pg/mL in healthy control group,(335.0?30.3) pg/mL in untreated group and (807.2?62.6) pg/mL in treated group.In HIV-1 infected patients,the levels of RANTES and MCP-1 were significantly increased.After highly active antiretroviral therapy (HAART),the level of RANTES declined,but MCP-1 increased further.Western blot assay revealed that the three recombinant proteins could be recognized by monoclonal antibodies respectively.All of them could chemoattract human peripheral blood mononuclear cells(PBMCs).And the chemoattractant potency of MCP/RANTES fusion protein was stronger.When the recombinant proteins were used with con- centrations as 50,200,400 and 800 pg/mL,respectively,the number of PBMCs chemoattracted by MCP/RANTES fusion protein was 52?10~4/mL,102?10~4/mL,132?10~4/mL and 184?10~4/mL; the number of PBMCs chemoattracted by RANTES was 27?10~4/mL,51?10~4/mL,65?10~4/mL and 96?10~4/mL;the number of PBMCs chemoattracted by MCP-1 was 18?10~4/mL,44?10~4/mL, 54?10~4/mL and 74?10~4/mL.Conclusion RANTES and MCP-1 may both be involved in the HIV infection process and host immunological reaction against HIV.

Compound algin capsule (CAC) was developed to treat the patients with Helicobacter pylori (HP)positive gastritis and digestive ulcer. The results showed that the e-liminating rate of HP was 67.4%,the disappeating rate of gastritis was 75%,and the ulcer healing rate 97. 8%. The symptom relief rate in CAC group was 88% ,which was significantly higher than the control group (68. 6% ,P

Objective To detect ESBLs in E.coli and K.pneumoniae with appropriate method.Methods The suspiciously produced ESBLs were detected by standard screen test among 110 E.coli and 84 K.pneumoniae. ESBLs possessing strains were confirmed by E test, single disc diffusion test with clavulanic acid or sulbatan, and two kinds of double disc synergy test. Results There was a significant difference between the detected rate of ESBLs in E.coli (16/26) and K. pneumoniae (4/20) by E test( P 0.05). The single disc diffusion test with clavulanic acid or sulbatan was applicable to confirm ESBLs in K. pneumoniae (12/20). Conclusions Single disc diffusion test is a sensitive, convenient and inexpensive method to confirm ESBLs in E.coli and K.pneumoniae in clinical laboratory.

Objective:In order to understand the professionals' ethical ideas and provide references for ethics education, and try to set up Chinese ethical code, the ethical beliefs of Chinese counselors and psychotherapists were investigated. Methods:145 Chinese counselors and therapists were asked to fill up an ethical questionnaire which was translated from the survey developed by Gibson and Pope in 1993 in the United States. The results of the survey were analyzed and compared with that of American professionals. Results: Chinese participants showed strong ethical beliefs in general, but they need more training in the aspect of informed consent. There were apparent culture differences on some aspects between two samples. Some significant gender and age differences could also be found. The authors believe that ethical training should be considered as an important way to enhance the professionals' awareness on ethical codes.

Objective To investigate the infectious features of rubella virus (RV) JR 23 strain in central nervous system (CNS). Methods RV JR 23 strain infected human primary cerebral neural cell culture in vitro and Balb/c mice, which were given dexamethasone and cytoxan before infection, via peritoneal injection. Viral pathogenecity was observed postinfection and RV antigens were detected in human cerebral neural cells by IFA and immunohistochemical method. Cerebral tissues were observed by HE staining and ABC methods postinfection.Results JR 23 strain didn't produce cytopathic effect (CPE). The proliferation of JR 23 strain reached highest titer of 10 3TCID 50 /ml at 72 h postinfection and decreased gradually. RV antigens were positive in cerebral neural cells, especially around the nuclei. Focal cytopathic areas were observed in cerebral cortical area and so did neuron necrosis around by gliacytes formed stellitorsis, neuronophagia and glial nodule. RV antigens could be seen in all cerebral area, but most localized in cortical area. Pathological features were basically the same among the infected groups. The infection rates of de xamethasone, cytoxan group and the group without intervention were 60%、90% and 50%, repectively. Conclusion RV JR 23 strain is not cytocidal to human neural cells and the pathological lesions induced by JR 23 strain in CNS of mice are mainly focal or dotted neuron necrosis.
