Objective:To investigate the relationship of micro-inflammation,cellular and humoral immune function and kidney disease of patients with diabetic nephropathy. Methods:124 cases of DN were randomly divided into normal albuminuria group ( NA, n=35),microalbuminuria group (MA,n=45) and clinical albuminuria groups(CP,n=44) based on 24 h urinary albumin excretion rate ( UAER) and the healthy subjects were selected as the control group ( n=35 ) . The levels of C-reactive protein ( CRP ) were measured with radioimmunoassay,the levels of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α) and humoral immunity(IgG enzyme-linked immunosorbent assay,IgA,IgM) were measured with ELISA. The levels of immune response ( CD4+Th17,Th17/Treg, CD4+ CD25+ Treg) were measured with flow cytometry cellular. The levels of creatinine ( Scr) ,cystatin C ( CYSC) and UAER of each groups were analyzed with fully automated biochemistry. Results:The levels of CRP,IL-6,TNF-α,Scr,CYSC,UAER of NA group,MA group,CP groups were higher than control groups(P<0. 05),the levels of CRP,IL-6,TNF-α,Scr,CYSC,UAER of CP groups were higher than NA,MA group (P<0. 05). The levels of CD4+CD25+ Treg,IgG were lower than the control group (P<0. 05),while the levels of CD4+ CD25+ Treg,IgG of CP groups were higher than NA group,MA group (P<0. 05). The levels of IgA,IgM,Th17/Treg, CD4+ Th17 of NA group,MA group,CP groups were higher than control groups(P<0. 05). The levels of CRP,IL-6,TNF-α were positively correlated with Scr, CYSC, UAER ( P<0. 05 ) and were negatively correlated with Th17/Treg, CD4+CD25+ Treg, IgG ( P<0. 05). Conclusion:DN patients with micro inflammatory status and immune function disorder,through the control or elimination of pro-inflammatory factors,improve the immune function of DN patients to delay the occurrence and progress of DN patients has important significance.

Objective:To study the change of the expression of heat shock protein 70 and ultrastructure of brain in sleep deprivation(SD).Methods:44 male Sprague-Dawlay rats were randomly divided into 11 groups.The HSP70 positive cells were detected by using immunohistochemical methods.The ultrastructure of hippocampal neuron was observed through electromicroscope.Results:HSP70 were detected in the cerebral cortex and hippocampus after SD.The HSP70 could be found after 12 h SD,reached to a peak during 2-3 d SD,and declined after 7 d SD.The number of HSP70 positive cells of SDd12h group was markedly more than that of SDn12h group(P

Objective To observe the clinical efficacy and safety of Danshen Chuanxiongqin injection combined with Isosorbide dinitrate on the treatment of myocardial ischemia.Methods 78 patients with myocardial ischemia from January 2015 to July 2016 were divided into the observation group and the control group, with 39 cases in each group.The control group received Isosorbide dinitrate therapy, the observation group received Danshen Chuanxiongqin injection joint Isosorbide dinitrate therapy.To analysis the clinical efficacy,electrocardiogram, TG,TC,the whole blood high and low-shear viscosities and adverse reactions between two groups.Results After treatment, total effective rate of the observation group was 89.74%, higher than the control group with 66.67%( P<0.05 ) .After treatment, ST segment depression occurred frequency and ST segment depression duration time of two groups were lower than before treatment(P<0.05),ST segment depression occurred frequency and ST segment depression duration time of observation group were lower than the control group (P<0.05).After treatment, TG and TC level of two groups were lower than before treatment(P<0.05),TG and TC level of the observation group were lower than the control group (P<0.05).After treatment,the whole blood high and low-shear viscosities of two groups were lower than before treatment(P<0.05),the whole blood high and low-shear viscosities of the observation group were lower than the control group ( P <0.05 ) .During treatment, there was no significant difference in adverse reaction rate between the two groups.Conclusion Danshen Chuanxiongqin injection combing with Isosorbide dinitrate has a better efficacy on the treatment of myocardial ischemia than only Isosorbide dinitrate ,and it is a safe treatment therapy.

OBJECTIVE: To investigate osteopontin (OPN) expression in plasma and tissue of patients with layngeal squamous cell carcinoma and analyze its role in invasion, metastasis, and clinical significance in laryngeal quamous cell carcinoma. METHOD: Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry were used to detect expression of OPN in plasma and tissue of 60 cases of laryngeal squamous cell carcinoma, 20 cases of adjacent normal laryngeal tissue and 20 cases of plasma from healthy subjects. RESULT: The expression of plasma OPN was closely correlated with clinical stage and cervical lymphatic metastasis in laryngeal squamous cell carcinoma (P < 0.05), but no significant correlation with the tumor location, pathological grade, gender and age (P > 0.05). The expression of OPN increased in plasma during cancer development: laryngeal squamous cell carcinoma (38.089 ± 9.225) ng/ml, healthy subjects (18.563 ± 9.308) ng/ml. There was a significant difference between the groups (P < 0.05). The expression of OPN in tissue was closely correlated with clinical stage (P < 0.05), pathological grade (P < 0.05) and cervical lymphatic metastasis (P < 0.05) in laryngeal squamous cell carcinoma adjacent atypical hyperplastic epithelium and carcinoma. The expression of OPN increased in tissue during cancer development: laryngeal squamous cell carcinoma (56.67%), adjacent normal laryngeal tissue (15.00%). There was a significant difference between the groups (P < 0.05). Elevated expression of plasma OPN is positively correlated with the expression of OPN in tissue in laryngeal squamous cell carcinoma patients (r = 0. 871, P < 0.05). CONCLUSION OPN plays an important role in the infiltration, metastasis and carcinogenesis in laryngeal squamous cell carcinoma. Combination of serum OPN, tissue OPN detection can be used as diagnostic and surveillance indicators for laryngeal squamous cell carcinoma infiltration and metastasis.
