Objective: To identify the related psychosocial risk factors of emotional disorders in children. Methods:To use case-control approach in which. Diagnosis was made by clinical interview according to ICD-10 criteria. Eighty eight cases and controls separately filled out general condition inventory. The results were put into Logistic regression model for analysis. Results: The children with timid personality, without kindergarten education, or with parents who were administrative or technical personnel, were apt to have emotional disorders. The children who were usually counseled by their mothers had less emotional disorders than those were beaten. Conclusion: The emotional disorders were the results of multiple factors. Prevention of children's emotional disorders should be focused on the children's personality and family education.

Objective To study the relationship between the complete blood count (CBC) and coal‐buring caused fluorosis of fe‐male rats .Methods Female SD rats were randomly divided into three groups :control group ,medium‐fluorine group and high‐fluo‐rine group .Rats in each exposed group were fed with fodder containing different proportions of corn dried by burning coal from flu‐orosis endemic areas to establish coal‐burning fluorosis model (fluoride of fodder were 47 .8 mg/kg and 96 mg/kg) .The corn of control group′s fodder was collected from non endemic areas (fluoride was 5 .2 mg/kg) .At 60 days ,120 days and 180 days ,the tail vein bloods were analyzed with automated analyzer .Results Compared with medium‐fluorine group ,the WBC of high‐fluorine group decreased at 60 d and 120 d(P<0 .05) .Compared with control group ,the RBC of fluoride treated groups decreased at each time point (P<0 .05) ,especially at 120 d .At 60 d and 120 d ,the Hb ,HCT and MCV decreased(P< 0 .05) .At 180 d ,only the MCV of high‐fluorine group increased obviously(P<0 .05) .At 120 d ,the Hb ,HCT of fluoride treated groups were less than those at 60 d and 180 d (P<0 .05) .The MCV of high‐fluorine group was same as above(P<0 .05) .At 180 d ,the MCV of medium‐fluo‐rine group decreased less than that at 60 d (P< 0 .05) .The MCH of fluoride treated groups increased at each time point (P<0 .05) .At 120 d ,the MCH of medium‐fluorine group increased more than its at 60 d and 180 d (P<0 .05) .At 180 d ,the MCH of higher‐fluorine group increased than those at 60 d (P<0 .05) .Conclusion Fluorosis has varied influence on blood cell of SD rats , especially on red blood cell system .In the early and mid stages ,the coal‐buring caused fluorosis showed the small RBC high pigment anemia .In the late stage ,the coal‐buring caused fluorosis showed the big RBC high pigment anemia .

Objective To explore the relationship between intrahepatic expression of interleukin-17 (IL-17) and liver fibrosis in patients with chronic hepatitis B virus infection. Methods IL-17 expressions in livers with different inflammation activity grades and hepatic fibrosis stages from patients with chronic hepatitis B virus carriers (n= 30), chronic hepatitis B (CHB, n = 55), liver cirrhosis (LC, n=20) were measured by immunohistochemistry. Serum IL-17 and liver fibrosis indices of haluronic acid (HA), laminin (LN), type Ⅲ procollagen (PC Ⅲ ) and type Ⅳ collagen ( Ⅳ C) were determined by enzyme linked immunosorbent assay (ELISA). The differences between groups were compared by Kruskal-Wallis test, and the Mann-Whitney test, and the correlation analysis was done by Spearman test. Results Intrahepatic IL-17 expression in LC group was significantly higher than CHB group (x2 =25. 3982, P=0. 004), and that in CHB group was higher than chronic hepatitis B virus carriers group (x2 = 11. 5056, P= 0. 001). The inflammation activity grade and hepatic fibrosis stage were both positively correlated with IL-17 expression (r= 0.718, 0. 693, respectively; both P＜0.01). IL-17 mainly located in portal area and the expression was positively correlated with serum levels of HA, LN, PCⅢ and ⅣC (r=0. 793, 0. 834, 0. 722, 0. 883, respectively; all P＜0.01).Conclusion Intrahepatic IL-17 expression is closely correlated with liver inflammation activity grade and hepatic fibrosis stage.

OBJECTIVE:To explore the effects and safety of atorvastatin combined with probucol on the vascular elasticity in patienits with hypertension. METHODS:246 hypertensive patients were randomly divided into control group and observation group,123 cases in each group. All patients received conventional antigypertensive treatment,based on it,control group was given 10 mg Atorvastatin tablet,qd;observation group was additionally given 0.25 g Probucol tablet,qd,on the basis of control group. They were treated for 1 year. Clinical efficacy,lipid levels(total cholesterol,triglyceride,low density lipoprotein cholesterol,high density lipoprotein cholesterol),cystatin C (Cys-C),C-reactive protein (CRP),elastic parameters of common carotid artery and lower limb artery(stiffness,pressure-strain elastic modulus,compliance,augmentation index,pulse wave velocity)before and af-ter treatment in 2 groups were observed,and the incidence of adverse reactions was compared. RESULTS:Before treatment,there were no significant differences in lipid levels,Cys-C,CRP and elastic parameters of common carotid artery and lower between 2 groups (P>0.05);after treatment,the above-mentioned indexes were significantly improved,and the improvement degree in ob-servation group was superior to control group,the differences were statistically significant(P<0.05). And there were no severe ad-verse reactions during treatment in both 2 groups. CONCLUSIONS:Atorvastatin combined with probucol can improve lipid level and elasticity of common carotid artery and lower limb artery,with good safety.
