Objective To study the relationship between Kazakh hypertensive patients with blood uric acid ,lipid levels and psy-chological factors .Methods 90 Kazak patients with hypertension in our hospital from January to August 2012 were randomly se-lected as the hypertension group and contemporaneous 171 non-hypertension patients as the healthy control group .Blood uric acid (UA) ,triglycerides(TG) ,total cholesterol(TC) ,low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein choles-terol(HDL-C) were detected and the perceived stress scale(PSS) was adopted to assess the mental status .Results The mean val-ues of TG ,TC ,HDL and LDL in males of the hypertension group and the mean values of UA ,TG and LDL in females of the hyper-tension group were significantly higher than those in the normal control group after adjusting age and BMI (P<0 .05);in the hyper-tension group ,UA was positively correlated with TC (r=0 .221 ,P<0 .05) .The level of perceived stress was positively correlated TC and LDL(r=0 .473 ,P<0 .05;r=0 .321 ,P<0 .05) and negatively correlated with TG and HDL (r= -0 .461 ,P<0 .05;r= -0 .412 ,P<0 .05) after adjusting age ,sex and BMI .Conclusion The blood lipid level in Kazakh hypertensive patients has certain correlation with the perceived stress .

Objective To explore the relationship between TLR3 mRNA expression on peripheral blood mononuclear cells(PBMCs)and acute rotavirus(RV)diarrhea.Methods Sixty-one children with acute RV diarrhea served as study subject,the expression of TLR3 mRNA on PBMCs was detected by real-time fluorescence quantitative RT-PCR.the concentrations of IFN-γand TNF-α in serum were measured by the method of Enzyrme-linked immunosorbent assay(EUSA).Results The expression of TLR3 on PBMCs and the serum levels of IFN-γ and TNF-α in the serious diarrhea group were 0. 820±0.051,(33.67±12.88)Pg/ml, (62.21±14.65)pg/ml,respectively,while it were 0.717±0.040,(24.01±10.06)pg/ml,(50.99± 12.18)pg/ml in the slight diarrhea group,and 0.525±0.029,(12.52±5.19)pg/ml,(28.65±7.44)pg/ml in the control group.Compared with the control group.the expression of TLR3 on PBMCs and the serum levels of IFN-γ,TNF-α in the serious and slight diarrhea group were significantly higher(P<0.01).There were significant differences between the serious and slight diarrhea group(P<0.01).There were positive relationship between the expression of TLR3 on PBMCs and tHe serum IFN-γ,TNF-α levels(r=0.431,P< 0.05,r=0.372,P<0.05).Conclusion The expression of TLR3 on PBMCs in children with acute rotavirus dialThea iS up-regulated,TLR3 and its mediated immune response are associated with the development of acute rotavirus diarrhea.

Fifty-six patients with Graves' ophthalmopathy(GO)were treated with antithyroid drug and oral prednisone for three months,TSH receptor antibody(TRAb)level was reduced,GO activity and severity of some patients were ameliorated but still positively associated with TRAb.It suggests that TRAb not only triggers off GO but also plays a possible role in the maintenance of the autoimmune process in GO.

Objective To evaluate the value of ultrasound (US) in assessment knee joint inflammation in patients with juvenile rheumatoid arthritis(JRA).Methods US scans of the knees obtained in 30 children at clinically active stage; JRA was compared with those obtained in 30 healthy children and 10 JRA patients in clinical remission.Results Changes in synovial membrane thickness and presence of fluid in suprapatellar bursa showed statistically significant differences between JRA patients with active disease and the other subjects.Alterations in contour of the articular cartilage were demonstrated in 10 knees of patients with JRA.Conclusion US is a simple sensitive and reliable methods for the assessment and monitoring of knee joint involvement in JRA.

OBJECTIVETo investigate the effect of Liuwei Dihuang Soft Capsule(LDSC) and Ginkgo Leaf Tablet (GLT) on serum regulated upon activation, normal T cell expressed and secreted (RANTES) in the patients with diabetes mellitus type 2 (DM2).

METHODSForty patients with early stage DM2 were randomly assigned to two groups, 20 in each group. Based on the conventional treatment with hypoglycemic agents, patients in the treated group were treated with LDSC plus GLT additionally, and those in the placebo group with placebo for 6 months, respectively. The levels of serum RANTES, blood glucose, blood lipids and glycosylated hemoglobin, as well as micro-content of albumin in urine were measured before and after treatment.

RESULTSIn the treated group, the serum level of RANTES decreased significantly after treatment, and it was significantly lower as compared with that in the control group (P < 0.05).

CONCLUSIONSLDSC and GLT can decrease serum RANTES level in patients with DM2. They play a preventive and therapeutic role on diabetic complications by their anti-inflammatory effect.
