Objective To understand the epidemic situation of Hepatitis B of the children and the situation of Hepatitis B vaccine injection in Maanshan city so as to provide the basis for the development of Hepatitis B vaccination strategy or adjustment in all of the people. Methods Two-stage sampling method was designed to survey 978 children under the age of 15 in 8 villages, with 3～5 ml of venous blood brawn and HBVM detected by ELISA. Results HBsAg positive rate of the children under the age of 15 was 10.12% in 1991 and, compared with the present rate at 0.92%, there was a significant difference. The protection rate of Hepatitis B vaccination was 90.91%. HBsAb positive rate of the children under the age of 15 was 40.49%, and the distribution was balanced among regional, urban and rural areas. With the in crease in age, the trend of Hepatitis B antibody levels declined, but the 1～5 age group had lower peak. The survey rate of Hepatitis B vaccine injection of the children under the age of 15 was 91.82%, and the report rate was 87.89%. The regional difference for them was significant. With the in crease in age, the rate of Hepatitis B vaccine injection declined for the survey and the report in all of the children under the age of 15. Conclusions The effect of Hepatitis B Control for 16 years is very significant in the city. It is necessary to administer charge-free Hepatitis B vaccination for the newborns and to strengthen the Hepatitis B vaccination in flowing children.

Objective To clarify the role of transmembrane protein 66(TMEM66) in intima proliferation of carotid artery induced by balloon injury in rats.Methods SD rats were randomly divided into three groups (n=10), including control group, the left carotid artery balloon injury group and injury group added with lentiviruses, respectively.Accordingly, the intima proliferation of carotid artery were detected by H/E staining;the expressions of TMEM66 in carotid artery injuried by balloon were determined by Western blot,q-PCR and immunohistochemistry, and the migration and proliferation of VSMCs were measured by scratch test and CCK8 respectively.Results Compared with control group, the expression of TMEM66 in carotid artery was obviously decreased after balloon injury (P<0.05).Most importantly, the intima proliferation of carotid artery was significantly reversed by overexpression of TMEM66 via specific lentiviruses (P<0.05).Conclusions TMEM66 is able to attenuate the intima proliferation of carotid artery after balloon injury.It could be that upregulation of TMEM66 can alleviate the migration and proliferation of VSMCs by PDGF.

Objective To investigate the serum levels of uric acid (UA) in bipolar disorder patients and their clini?cal significance. Methods Serum levels of UA was measured in 126 bipolar disorder patients including 77 mania pa?tients and 49 depression patients, 69 first-episode schizophrenic patients and 126 healthy controls (control group). Bipo?lar disorder patients was assessed by using the Young Mania Rating Scale (YMRS) and the Hamilton Depression Scale (HAMD). Results The serum UA levels were significantly higher in bipolar group [(349.34 ± 107.21) μmol/L] than in schizophrenic group [(319.71±84.48)μmol/L] and in control group [(280.94±71.90)μmol/L] (P<0.01). There were signifi?cant differences in serum UA levels between manic episode and depressive episode [(366.45 ± 104.01) μmol/L vs. (322.45±107.69)μmol/L]. The serum UA levels were higher in both manic episode and depressive episode groups than in control group (P<0.01). The serum UA levels was not significantly different between patients with and without medication (P>0.05). Correlation analysis indicated that the correlation of serum UA levels with YMRS scores and HAMD scores was not significant in bipolar disorder patients (P>0.05). Conclusions Patients with bipolar disorder has elevated serum uric acid levels which may be a biomarkers of bipolar disorder.

Objective To investigate the effects of morroniside on fibrinogen (Fib), prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT) in focal cerebral ischemia/reperfusion in rats. Methods The animal model was induced with occlusion of middle cerebral artery (MCAO) with suture embolus, and morroniside was then administered intragastrically at the dose of 30, 90 and 270 mg/kg for 7 d. Acetyl salicylic acid was taken as positive control drug. The content of Fib, and PT, APTT and TT were measured withrelated kits. Results Compared with the sham-operated group, the concentration of Fib significantly increased (P<0.001) and PT, APTT and TT significantly shortened in the model group (P<0.001); however, compared with the model group, morroniside significantly decreased Fib content (P<0.01) and prolonged PT, APTT and TT (P<0.05). Conclusion Morroniside can antagonize the coagulation function in focal cerebral ischemia/reperfusion in rats.

Objective To investigate the relationship between the different ambulatory arterial stiffness index and the markers of renal impairment in order to provide a scientific method for detecting the renal impairment of essential hypertension. Methods Three hundred essential hypertensive patients without overt proteinuria were enrolled. The ABPM was performed and the blood pressure parameters were analyzed in order to estimate the symmetrical ambulatory arterial stiffness index (S-AASI) and ambulatory arterial stiffness index (AASI) . Microproteinuria was measured by urine microalbumin to creatinine (mAlb/Cr)as well as n-acetyl-β-D-glucosaminidase (NAG)to creatinine rate (NAG/Cr). Creatinine clearance (Ccr) and Glomerular filtration rate (eGFR) were estimated from serum creatinine (sCr) . Linear correlations were performed to confirm the independent predictive power of S-AASI and AASI for renal lesion. Results Correlation test showed a significant positively relationship of S-AASI with urine mAlb/Cr (0.708, <0.001), urine NAG/Cr (0.700, <0.001) and sCr (0.229, <0.05) . Ccr (0.601, <0.001) and eGFR (0.309, <0.05) were negatively correlated with S-AASI. On the other hand, AASI was also correlated with urine mAlb/Cr (0.489, <0.001),urine NAG/Cr (0.470, <0.001) and Ccr (0.311, <0.05),but not with the sCr (0.064, >0.05) and eGFR (-0.135, >0.05) . S-AASI seems to get an independent relationship with all of the parameters of renal impairment which could not be detected with AASI. Conclusion This results suggested that S-AASI may be a better approach than AASI to estimate hypertensive renal impairment.
