Aim To study the effect of oxymatrine (OMT)on protecting human umbilical vein endothelial cells (HUVECs)from toxicity induced by high glucose in vitro.Methods The HUVECs were cultured with medium containing different concentrations of glucose or OMT. The cells were randomly divided into 6 groups:5.5 mmol·L -1 control group(Control),22.2 mmol·L -1 high glucose (22.2 mmol·L -1 ),44.4 mmol·L -1 high glucose (44.4 mmol·L -1 ),control+OMT(control +OMT),22.2 mmol·L -1 high glu-cose +OMT(22.2 mmol·L -1 +OMT),44.4 mmol ·L -1 high glucose +OMT (44.4 mmol · L -1 +OMT).The protective effect of oxymatrine was as-sessed by MTS assays.The expression of A2B in HU-VECs was detected by Real-time quantitative PCR (qPCR)and Western Blot methods.Results The glucose was shown to have caused cytotoxicity in HU-VECs.Oxymatrine (3 μmol·L -1 )was found to have protected HUVECs from glucose toxicity effectively, and reduced the expression of A2B significantly.Con-clusion Oxymatrine can obviously protect HUVECs from cytotoxicity induced by high glucose and the effect is performed partly by decreasing A2B expression.

Intracerebral hemorrhage is a neurological emergency with high disability and mortality. Studies have demonstrated that thrombin formation,erythrocytolysis and iron ions play important roles in the brain injury after intracerebral hemorrhage. This article reviews the mechanisms of thrombin and iron ions in intracerebral hemorrhage-mediated brain injury.

Objective:To study the effect of Jianpi Qinghua Recipe ( JPQHR) on angiotensin II/NADPH oxidase pathway in 5/6 nephrectomized rat renal failure model and the underlying mechanisms.
Methods:The animals were divided into 4 groups:the sham-operated group, the renal failure group, the JPQHR-treated group and the losartan-treated group. After 60-days therapy, serum nitrogen and creatinine were measured. The expression of angiotensin II type 1 receptor (AT1) protein and the expression of p47phox mRNA in renal tissue was determined. SOD and MDA were also examined.
Results:Compared with the sham-operated group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in the renal failure group were significantly increased. hTe activities of SOD in renal tissue from the renal failure group was signiifcantly down-regulated while MDA was up-regulated (P<0.05). Compared with the renal failure group, the levels of SCr and serum BUN and the AT1 protein and p47phox mRNA expression in both JPQHR-treated group and losartan-treated group were signiifcantly decreased. hTe activities of SOD in renal tissue from JPQHR-treated group and losartan-treated group were signiifcantly up-regulated whereas the content of MDA were down-regulated (P<0.05). Compared with the losartan-treated group, the activities of SOD in renal tissue from the JPQHR-treated group was obviously increased (P<0.05), the decrease in AT1 protein and p47phox mRNA was more evident but not statistically different (P>0.05). The level of SCr and serum BUN and the content of MDA were also not statistically different (P>0.05).
Conclusion:hTrough decrease the expression of angiotensin II and NADPH oxidase, JPQHR can reduce the oxidative stress in chronic renal failure and delay the renal ifbrosis progression.

Objective To evaluate the relationship between asthma and rhinitis in children.Methods One hundred and thirty children with rhinitis were divided into two groups.Among them,60 displayed rhinitis alone and 70 displayed rhinitis associated asthma.The following parameters were analyzed between two groups: age,sex,history of eczema,familial history of smoking,familial history of asthma,sensitization to allergens,level of total serum IgE,blood eosinophil count.Logistic regression analysis was used to analyze the effect of covariates on risk of rhinitis or asthma.Results History of bronchiolitis,familial history of asthma,maternal asthma and sensitization to allergens h_1(greer labs inc),d_2(dermatophagoides farinae) were significantly more frequent in asthmatic subjects.In these patients,the total serum IgE and eosinophil count were higher.Logistic regression analysis showed that a high eosinophil count and total serum IgE significantly increased the risk of developing asthma in patients with rhinitis.Conclusions In subjects with rhinitis,the occurrence of asthma is related to history of bronchiolitis,familial history of asthma,atopy,total serum IgE levels and blood eosinophilia.In rhinitis subjects,these parameters will be taken into account to manage underlying asthma.

Objective To discuss the significance of serum IgE before and after inhale glucocorticoid treat-ment of children's asthma. Methods 520 children with asthma were seleceted from the outpatient. Different type of fluticasone propionate were given to different age groups: Aerosol type by a spacer in less than 5 years old,and in-halant (Seretide) 5 years and the above. The dosage was between 200 μg/day to 375 μg/day. IgE was tested before and 3 months after the treatment. Results Serum IgE decreased significantly in 3 months treatment [ from (496.12±24.75) kU/L to (390.71±18.71) kU/L] (t=7.337,P<0.01). The change of IgE was related to clinical effect and age. The level increased in those less than 3 years [(307.05±34.71)kU/L vs (483.09±41.78) kU/L] (t=2.963,P=0.004),but decreased between 4 to 5 years old group [(543.46±51.03) kU/L vs (316.93±29.30) kU/L] (t=3.368,P=0.000) ,and decreased between 6 to 14 years old group[ (586.30±37.19)kU/L vs (387.61±27.60) kU/L] (t=4.827,P=0.000). In fluticasone group IgE level changed from (468.91±32.81) kU/L to (359.03±22.79) kU/L after treatment (t=5.988,P<0.01),which decreased from (586.30±37.19) kU/L to (387.6±27.60) kU/L in Salmeterol group (t=4.827,P<0.01). In 260 cases of IgE below 300 kU/L 109 cases (41.92%,109/260) increased while in 260 cases of IgE above 300 kU/L,total IgE lev-el increased in 45 cases (16.15% ,45/260) after treatment,with statistical significance(χ<'2>=37.789,P=0.000). Conclusion Inhale glucocorticoid can make the level of IgE decreased.
