Objective To determine the feasibility of human routine blood tests as a surrogate for CD4+ T cell count through studying the correlation of CD4+ T cell count with total lymphocyte count(TLC),hemoglobin(Hb),blood platelet(PLT),and white cell count(WBC)in HIV/AIDS patients.Methods 1 038 person-time blood tests among 778 HIV/AIDS patients were performed and Spearman correlation analysis was used.Predictive power and the cut-off for potential predictors of CD4+ T cell count were assessed through receiver operating characteristic(ROC)curves.Combination test was used to assess the capability of multipie indexes to serve as surrogate markers for CD4+ T cell counL Results Significant correlations with CD4+ T cell count were observed for TLC,Hb,PLT and WBC.The Spearman correlation coefficients were r=0.64,P=0.000;r=0.36,P=0.000;r=0.24,P=0,000;r=0.09,P=0.000,respectively.No correlation between TLC and CD4+ T cell count was found when,TLC was more than 2 000 × 106/L(r=0.12,P=0.15).The areas under ROC curve of TLC and Hb for predicting CD4+ T cell count were between 0.82 to 0.84,and 0.66 to 0.70,respectively.When CD4+ T cell count were less than 50,200,350 cells/μl respectively,the optional cut-off value was TLC＜1 100 × 106/L,1 200 × 106/L and 1 400 × 106/L.When the study combined TLC＜1 200 × 106/L and Hb＜120 g/L for prediction of CD4+ T cell count＜200/μl,the sensitivity was 45.3% and specificity was 82.8%.Conclusion There is no significant application value for combination of TLC＜1 200×106/L and Hb＜120 g/L as a surrogate for prediction of CD4+ T cell count＜200/μl.

Objective:To further explore the relationship between Type Ⅰ hypersensitivity reaction and the mechanism of the viral hepatitis B through the research of soluble intercellular adhesion molecular-1(sICAM-1) and soluble vascular cell adhesion molecular-1(sVCAM-1) levels in serum in patients with viral hepatitis B related to Type Ⅰ hypersensitivity reaction and the damage of liver cells, and therefore, provide new theory for the perfection of the immunological mechanism of hepatitis B, especially acute hepatitis B.Methods:Serum sICAM-1 and sVCAM-1 levels were measured in 45 patients with viral hepatitis B and 15 normal cases using double antibody sandwich ELISA method. ALT and AST levels were studied using omni automatic biochemistry analyzer and its correlation with sICAM-1 and sVCAM-1 were observed.Results:The sICAM-1 and sVCAM-1 levels of 7 acute hepatitis B were significantly higher than that of the normal cases. ②The sICAM-1 and sVCAM-1 levels of 38 chronic hepatitis B were also significantly higher than that of the normal cases. ③The sICAM-1 and sVCAM-1 levels of 13 cases moderate chronic hepatitis B were significantly higher than that of 16 cases mild chronic hepatitis B. ④The sICAM-1 and sVCAM-1 levels of 9 serious chronic hepatitis B were significantly higher than that of the group of mild chronic hepatitis B. ⑤Levels of sICAM-1 were significantly positively correlated with serum ALT and AST. ⑥sVACM-1 levels were significantly positively correlated with serum ALT and AST. In conclusion, sICAM-1 and sVCAM-1 levels in patients with acute hepatitis B were most remarkably increased, and then serious chronic hepatitis B, moderate chronic hepatitis B, light chronic hepatitis B in sequence.Conclusion:Serum sICAM-1 and sVCAM-1 levels in patients with viral hepatitis B may reflect the damage of liver. ②Examination of serum sICAM-1 and sVCAM-1 levels in patients with hepatitis B can be used to judge the patient’s condition and to diagnose. ③As an important indication of the inflammatory in Type Ⅰ hypersensitivity reaction, sICAM-1 and sVCAM-1 may interfere the appearence of hepatitis B and the procedure of immunological damage of liver cells.

Objective:To present evidence for the pathogenetic role of allergic factor,histamine,in type I allergy for induction of liver damage.Methods:Three groups of rabbits were fed normally and injected (iv) daily with 0, 0.04 or 0.08 ?g/kg phosphohistamine, respectively, for days. The serum level of ALT and AST in each group rabbits was assayed dynamically during the treatment. After treatment for days, the tested rabbits were sacrificed for pathological examination of the liver tissues.Results:The serum level of both ALT and AST in rabbits treated with phosphohistamine increased significantly during the tested periods, compared to that of the control group. However, both ALT and AST levels showed no significant difference between 0.04 ?g/kg and 0.08 ?g/kg groups. Liver microscopic examination, pathological damage could be observed in the tested groups in a time-and dose-dependent manner under microscopic examination. No evident pathological change appeared in the control group.Conclusion:Liver damage could be induced by histamine dosage-and time-dependently. This pathological action of histamine, a type I allergic factor, presents further evidence for a direct role of type I allergy in the pathogenesis hepatic injury.

To clarify the effect of the sympathetic nerves on the body's physiopathological changes and acupuncture effect by the alphal-AR mediation in the past 30 years.The paper has referred to the database of CNKI and Pubmed,and systematically reviewed the publications in the past 30 years about the research of the alphal-AR mediation of the sympathetic nerves to the body's physiological andpathological changes and acupuncture effect.Alphal-AR not only mediated the sympathetic nerves on the inotropic change of the heart,and the contraction of the vascular smooth muscles,bladder sphincter,and uterine smooth muscles and other physiological effect,but also mediated cardiac arrhythmia,myocardial hypertrophy and other pathological process.In addition,Alphal-AR also mediated the acupuncture signal transmission,and acupuncture was able to adjust the sympathetic nervous tension.The body's physiopathological changes are closely related to alpha1-AR and subtype alteration.The in-depth study of alphal-AR helps to explain physiopathological mechanism of the body,as well as provide theoretical basis and the corresponding pharmacological models for better selective drugs.Studying Alpha1-AR on meridians contributes to the discovery of meridian essence and the substantial basis of acupuncture effects.

Objective To observe the influence of head-down tilt on visual evoked potential.Methods Six healthy volunteers were exposed to-6? head-down tilt.The visual evoked potential were measured before the test,the second day and the fifth day of the test under different space frequency.Results No significant difference was found in the latency of P100 before and after the test.The amplitude of P100 had significant change under high space frequency.But not the same happened on middle and low space frequency.Conclusion head-down tilt can induce the change of visual evoked potential under high space frequency,which means the weightlessness may influent the visual function.
