Objectives To investigate the relationship between obstructive sleep apnea hypoventilation syndrome (OSAHS), insulin resistance (IR) and metabolic syndrome (MS), as well as to explore the possible mechanism of MS caused by OSAHS. Methods We recruited 186 hospitalized patients with hypertensions, who were divided into four groups based on their nocturnal polygraphs recordings, 35 as controls (group Ⅰ), 61 with mild (group Ⅱ), 52 with moderate (group Ⅲ) and 38 with severe OSAHS (group Ⅳ). They all underwent measurements including body height, body weight, waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP), serum uric acid, creatinine, fasting plasma glucose, fasting plasma insulin, serum total cholesterol, high-density lipoprotein-cholesterul, low-density lipoprotein-cholesterol and triglyceride. Results One hundred and two patients with OSAHS (67.6 percent) also suffered of MS, 33 (86.8 percent) of them with severe OSAHS. There was no significant difference in age, gender, fasting plasma glucose, total cholesterol, high-density lipoprutein-cholesterul, low-density lipoprotein-cholesterol and triglyceride among the four groups (P>0.05). Body mass index (BMI), WC, ratio of serum uric acid to creatinine and DBP were all significantly higher in patients with severe OSAHS than those in patients with mild and moderate OSAHS and controls (P<0.01). SBP was significantly higher in patients with severe OSAHS than that in those with mild and moderate OSAHS (P<0.01). Insulin resistance was significantly severer in patients with severe OSAHS than that in those with mild OSAHS and controls (P<0.01). Results of multivariate linear regression analysis showed that insulin resistance was correlated with BMI and reversely correlated with minimal blood oxygen saturation, and minimal blood oxygen saturation reversely correlated with WC and ratio of uric acid to creatinine. Condusions Hypoxemia and obesity may promote development of insulin resistance. Patients of hypertension complicated with OSAHS tend to develop MS, particularly in those with severe OSAHS.

Objective To assess the effectiveness of the quotient of serum sodium to urinary sodium divided by (serum potassium) 2 to urinary potassium (SUSPPUP) in screening for primary aldosteronism (PA).Methods Among 952 patients with hypertension who had renin activity,aldosterone measurements and concomitant serum and urinary biochemistry data,204 patients were diagnosed as cases of PA and 261 as cases of essential hypertension.Diagnosis of PA was made in accordance with established laboratory criteria including renin activity and aldosterone,plasma aldosterone concentration/plasma renin activity (ARR),and saline loading test.The SUSPPUP ratio with the ARR were compared in two groups.Results The area under the curve of SUSPPUP and ARR was 0.797 and 0.796 respectively according to receiver operating characteristic curve,optimal cutoff of SUSPPUP was 1.0,the sensitivity and specificity of SUSPPUP was 98.9% and 81% respectively.Conclusions The SUSPPUP ratio is an inexpensive and rapid tool to assess the extent of mineralocorticoid excess,therefore,SUSPPUP ratio can be applied to screen PA in hypertensive patients.

Objective To investigate the association between KCNJ5 gene polymorphism and primary hyperaldosteronism(PA).Methods A total of 248 PA patients and 816 essential hypertension (EH) patients were enrolled in this study,TaqMan assay was used to detect the rs1221497 polymorphism of KCNJ5 gene.Results The genotypes of rs1221497 were in Hardy-Weinberg equilibrium in both PA group and EH group,the genotype frequencies ofGG,GC,CC were 208,39,1 in PA group and 631,177,8 in EH group respectively,the allele frequencies in the two groups were 455,41 and 1 439,193 respectively.The frequencies of GG genotype and G allele in PA group were significantly higher than those in EH group.Logistic regression showed that GG genotype was closely associated with PA after adjusting age.Conclusions GG genotype and G allele may contribute to the occurrence of PA.

Objective To investigate the role of signal transduction of toll-like receptors(TLRs)in immunological pathogenesis in children with acute idiopathic thrombocytopenic purpura(ITP).Methods Thirty children with actue ITP and 30 age-matched healthy children were studied.Real-time fluorescent quantitative PCR was used to evaluate the levels of TLR 1-10 and signal transducing molecules,and cytokines associated with TLRs,such as IL-1?,granulocyte-macrophage colony-stimulating factor(GM-CSF),macrophage colony-stimulating factor(M-CSF)and IFN-?/? mRNA.Expressions of co-stimulatory molecules such as CD40,CD80 and CD86 in mo-nocyte/macrophage(MC)was analyzed by flow cytometry.Results Compared with healthy control group,the mRNA levels of TLR3,7,8 and 9 in ITP group were significantly up-regulated(Pa0.05).Transcription le-vels of MyD88-dependent and-independent pathway molecules such as MD-2,MyD88,IRAK-4,TRAF6,TAK1,TRIF,TRAM,TBK-1 and IFN-? were significantly up-regulated in acute ITP(Pa0.05).Conclusion Aberrant activation of toll-like receptors signaling may be one of the initiating factors of immune dysfunction in children with acute ITP.

One hundred and fifty-six patients with primary aldosteronism(PA)and 189 patients with essential hypertension (EH) were included in this study.The value of estimate glomerular filtration rate (eGFR) was calculated by MDRD equation.The plasma levels of aldosterone,triglycerides,creatinine and fasting glucose were measured.The plasma creatine,24 hour urine albumin excretion in PA patients were higher and eGFR and plasma aldosterone were lower than those in EH patients ( all P < 0.01 ).Multiple regression analysis revealed that the plasma concentrations of aldosterone ( P =0.003 ) and creatinine ( P =0.001 ) were independent predictors of eGFR.

ObjectiveTo explore the effect of the calcium phosphate cement (CPC) /calcium polyphosphate fiber (CPPF) composites mixed with different proportion of minimal morselized bone on repair of bone defect in vivo. MethodsA total of 36 New Zealand white rabbits were completely randomly designed into A, B, C, D groups and their bilateral radial bone defect model was prepared. The minimal morselized bone (300-500 μm in diameter) was made from the iliac of those rats. The CPPF and CPC were evenly mixed into CPC/CPPF composites which were divided into four groups in accordance with the CPPF weight O, 10%, 30% and 50% in CPC/CPPF composite. The CPC/CPPF composites of the four groups was mixed with the minimal morselized bone with ratio of 6:4 and then the mixture was implanted the bone defect of the rabbits in four groups. The gross, X-ray and histological observations were done at four and eight weeks. The biomechanical test was performed at eight weeks. Results When CPPF occupies 30% of the CPC/CPPF composite, the maximum compressive load and bending loads were better than those in the other groups ( P < 0.05 ), when the histological observation showed the most tight link between the artificial composite and the bone interface and the closest similarity between material degradation rate and the ossification rate, with the best osteogenesis and the optimal ratio.ConclusionThe repair of bone defect can attain the optimal outcome through adding a certain ratio of minimal morselized bone into the CPC/CPPF to adjust the degradation rate of composites.

0.05).There was significant difference in the 3-year survival rate between A and C group. Conclusions The 3-year survival rate was dramatically increased with combined therapy mainly by cisplatin, the dose of 60~80mg is tolerant for the elderly aged above seventy years, and perioperation complications can be cured.
