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.

OBJECTIVE:To set up a HPLC method for the determination of the contents of notoginsenoside R1,ginsenoside Rg1 and Rb1 in Sanqishangyao tablets.METHODS:It was performed on VP-ODS (150mm?4.6mm,5?m),and the mobile phase was acetonitrile-water with gradient elution system(0～20min(20∶80),20～26min(40∶60),26～35min(20∶80)).The flow rate was 1.0mL?min-1 and the column temperature was room temperature.The detection wavelength was 203nm.RESULTS:The liner range of notoginsenoside R1 was 0.261～7.83?g(r=0.999 9)and the average recovery was (101.12?2.03)%(RSD=2.1%).The liner range of ginsenoside Rg1 was 0.602 5～18.075?g(r=0.999 7)and the average recovery rate was (97.22?3.33)%(RSD=1.9%).The liner range of ginsenoside Rb1 was 0.537 5～16.125?g(r=0.999 6)and the average recovery rate was(100.71?2.4)%(RSD=1.6%).CONCLUSION:The method is suitable for the content determination of notoginsenoside R1,ginsenoside Rg1 and Rb1 in Sanqishangyao Tablets.

Background: The prevalence of ulcerative colitis (UC) in China has significantly increased in recent years,and Toll-like receptor 4 (TLR4) may be closely related to the development of UC.Aims: To study the effect of vitamin D3 on expression of TLR4 in the intestinal mucosa in colitis model in rats.Methods: Thirty Sprague-Dawley rats were randomly divided into normal control group,model group and vitamin D3 group.Rats in model group and vitamin D3 group were given trinitro-benzene-sulfonic acid (TNBS) to induce colitis model.Rats in vitamin D3 group were given vitamin D3.HE staining was performed,and disease activity index (DAI) and colon histopathological score were evaluated,the expression of TLR4 was measured by immunohistochemistry.Results: Compared with normal control group,DAI and histopathological score in model group were significantly increased (P＜0.05),and expression of TLR4 was significantly increased (P＜0.05).After giving vitamin D3,DAI and histopathological score were significantly decreased (P＜0.05),and expression of TLR4 was significantly decreased (P＜0.05).Conclusions: The expression of TLR4 is increased in colon tissue in colitis model in rats,which may be involved in the pathogenesis of UC.Vitamin D3 can alleviate intestinal inflammation via inhibiting expression of TLR4,thereby playing a role in the adjunctive therapy of UC.

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.
