Objective To observe the abnormal Minnesota code (MC) distribution and interrelated characteristic on electrocardiograms (ECGs) of the adult Kazakh population.Methods Resting ECGs and blood press of randomly sampled 30 000 adult Kazakh people in three Northern regions of Xinjiang were continuously examined and analyzed,using Minnesota code recommended by WHO as the classification of ECG.Results The overall rate of abnormal ECG findings was 248.60‰,and the main abnormality in males was 146.83‰,compared to 157.71‰ in females.The prevalence rates of abnormal ST-T changes,the total arrhythmia and atrial fibrillation (AF) were 100.03‰,71.17‰ and 2.83‰ respectively.There were statistically significant differences among the main abnormities from the three regions.Conclusion The ECGs abnormalities of adult Kazakh people were high.There was significant relation found between the main abnormalities and hypertension.The prevalence of AF was different from the domestically reported literature that calls for further study.

Jiangsu province is rich in intertidal marine resources,especially gastropod and bivalve shellfish.In this study,we performed shotgun proteomic analysis on shellfish from Lüsi,Jiangsu to identify protein content.In total,265 proteins were identified in nine species of shellfish using nano LC-MS/MS.The highest number of proteins were identified in the gastropod Hemifusus tuba (HF) (105 proteins),whereas the bivalve Scapharca subcrenata (SSC) produced the fewest (39 proteins).The most abundant proteins are constituents of cytoskeleton,including actin,tubulin,tropomyosin,myosin heavy chain,as well as histone proteins.Additional proteins were also identified,including ribosomal proteins,enzymes such as arginine kinase and ATP synthase,and housekeeping proteins such as elongation factor and heat shock protein.Proteins were classified based on cellular components and molecular function using the principal component analysis (PCA).Results of PCA analysis revealed that Sinonovacula constrzcta (SC),Bullacta exarata (BE) and Hemifusus tuba (HF) showed similar protein profiles,whileSolen strictus (SS),Meretrix meretrix (MM),Ruditapes philippinarum (RP),and Mactra veneriformis (MV) also showed similar protein profiles.Hierarchical clustering results of heat map studies showed that RP and Mactra antiquate (MA) were classified into one group.SC,BE,HF,MM,SSC,and MV were classified into another group.SS showed the furthest distance from this group.We established a method for analyzing and characterizing the protein composition characteristics of predominant shellfish species in Jiangsu providence's intertidal zone area,which provides basic data for the development of shellfish resources.

Objective To examine the relationship between hyperthyroidism and excessive iodine intake from drinking water through epidemiological studies in the iodine excess and the iodine normal villages. Methods Mengzhuang village of Pei county and Xingji village of Pizhou city in Jiangsu province, with median water iodine concentration of 1284.1 μg/L and 77.9 μ/L, respectively,were selected in 2006. Thyroid diseases of all local residents in the two villages were assessed clinically to compare the prevalence and the distribution of hyperthyroidism. Results A total of 17 471 residents were recruited from the iodine excess village, 26 of them were diagnosed with hyperthyroidism. The prevalence of hyperthyroidism was 1.49‰, 0.75‰ (7/9264) in male,2.32‰( 19/8207) in female, and the age-standardized prevalence was 1.48‰. A total of 12 765 residents were recruited from the iodine normal village, among them 27 residents were diagnosed with hyperthyroidism. The prevalence of hyperthyroidism was 2.12‰, 0.96‰(7/6823) in male, 3.26‰(20/5942) in female, and the agestandardized prevalence was 2.02‰. The prevalence and age-standardized prevalence was significantly lower in the iodine excess village than those in the iodine normal village (u = 2.88, 2.89; all P < 0.01). The prevalence of hyperthyroidism was lower among females in the iodine excess village (2.32‰) than that in the iodine normal one (3.37‰, u = 2.89, P < 0.01). Residents aged 20 - 50 years had higher prevalence of hyperthyroidism[(19.36 -38.96 )/10 000]in the two villages. The proportion of Graves diseases was 50.00% (13/26) in the iodine excessvillage, higher than that in the iodine normal village[29.41%(5/17) , χ2 = 5.853, P < 0.01]. Conclusions Chronic excessive iodine intake does not increase the chance of suffering from hyperthyroidism. On the contrary, the prevalence of hyperthyroidism in the iodine excess village decreases significantly compared with that of the iodine normal village. The prevalence is higher among females.

Objective To analyze the incidence and risk factors of hypothermia in elderly patients with malnutrition during proximal femoral nail antirotation(PFNA)internal fixation under general anesthesia.Methods A total of 139 elderly patients underwent PFNA internal fixation under general anesthesia were selected,and the nutritional status scores 1 day before surgery ranged from 0 to 11 points.Univariate and multivariate Logistic binary regression analysis was performed to analyze the related factors that may lead to intraoperative hypothermia.Results Among 139 elderly patients with preoperative nutritional scores of 0 to 11 points,79 cases(56.83%)developed intraoperative hypothermia.The results of univariate and multivariate Logistic binary regression analysis suggested that age≥75 years old,mini nutritional assessment short form(MNA-SF)nutritional score 0 to 7 points,BMI<18.5 kg/m2,duration of general anesthesia≥2 hours,intraoperative flushing fluid volume≥1 000 mL and intraoperative fluid volume≥1 000 mL were the risk factors for the occurrence of intraoperative hypothermia in elderly patients(OR>1,P<0.05).The use of warm blanket insulation was the protective factor against the occurrence of intraoperative hypothermia(OR<1,P<0.05).Conclusion The incidence of intraoperative hypothermia during PFNA internal fixation under general anesthesia in elderly patients with mainutrition before operation is high,and patients with poor nutritional status are more likely to develop intraoperative hypothermia.Patients with older age,poor nutritional status,lower BMI,longer duration of general anesthesia,and more intraoperative flushing fluid volume and intraoperative fluid volume are likely to lead to intraoperative hypothermia.The use of warm blanket can reduce the incidence of intraoperative hypothermia.

We systematically reviewed the results of the studies on expression regulation, biological functions, and clinical prognostic significance of CASP8AP2 gene. At present, the studies showed that the expression of CASP8AP2 gene was regulated by Homeobox proteins and DNA methylation, and could be silenced by miRNA-210. This protein was involved in apoptosis mediated by FAS and TNFα, NF-κB activation mediated by TNFα, regulation of gene expression induced by glucocorticoid and mineralocorticoid receptor, comprising Cajal body and histone locus body, transcription of replication-dependent histone, 3' end processing of histone, regulation of S phase progression, in addition to functioning as coactivator of transcription factors c-Myb and p73 to activating many genes' expression. On the other hand, low expression of CASP8AP2 gene was associated with relapse in childhood ALL. The deletion of this gene was related to the poor prognosis of children with T-ALL and T lymphoblastic lymphoma. Furthermore, 3 SNPs in this gene were possibly correlated with genesis of diffuse large B cell lymphoma and childhood leukemia. In conclusions, CASP8AP2 was a multifunctional protein. It could function to regulate cell proliferation, apoptosis, and gene expression. In childhood hematological malignancies, CASP8AP2 was a promising molecular marker with prognostic significance. Some SNPs were possibly correlated with leukemo- and lymphomogenesis.

OBJECTIVETo study the effect of Hongjingtian (Gadol) injection on cardiac hemodynamics and myocardial oxygen consumption for analyzing its underlying mechanism in the treatment of coronary heart disease.

METHODA total of 20 dogs anesthetized with pentobarbital sodium (30 mg x kg(-1), i.v.) were evenly randomized into control group, low-dose Gadol (LDG) group, high-dose Gadol (HDG) group and Herbesser Injection group. The blood flow volume (BFV) of the left coronary artery and cardiac output (CO), left ventricular pressure (LVP), maximum ascending rate (dp/dtmax) of LVP, mean arterial pressure (MAP) of the femoral artery, oxygen contents of the coronary artery and coronary vein (venous sinus), oxygen consumption index (OCI), cardiac index (CI), coronary artery resistance (CAR) and total peripheral resistance (TPR) as well as oxygen utilization rate (OUR) were detected respectively.

RESULTAfter venous injection of Gadol, CAR, MAP, TPR, OCI, myocardial oxygen consumption and heart rate lowered significantly (P < 0.05-0.01), while BFV and blood oxygen content of the venous sinus increased considerably (P < 0.05-0.01) in comparison with pre-injection. No significant differences were found in LVP and myocardial contractivity between control group and LDG, and between control and HDG groups respectively.

CONCLUSIONIt showed dilation of the coronary artery and reduction of the cardiac afterload after injection of Gadol. Besides, CO and stroke volume increased considerably and the cardiac effective work was raised without any significant simultaneous increase of both myocardial contractility and LVP. A decrease in the myocardial oxygen consumption and reduction of OCI indicates an improvement of the oxygen supply of the myocardium, and a favorable regulation of the compliance of the cardiac vessels. As a result, the cardiovascular performance was ameliorated. The abovementioned improvement of these indexes may contribute to the therapeutic effect of Gadol in the treatment of coronary heart disease in clinic.

Objective To determine the efficient cut-off points of fasting fingertip blood glucose test for undiagnosed diabetes mellitus(DM), impaired glucose tolerance(IGT), and impaired fasting glucose(IFG)in community-based residents aged above 45 years old. Methods A cluster-randomized study was conducted from May 2008 to January 2009. A total of 3250 subjects aged above 45 years in two communities of Baoding city received questionnaire investigation and tested for fingertip blood glucose. Those subjects whose capillary blood glucose level ≥5.1 mmol/L were subjected to 75 g oral glucose tolerance test. Undiagnosed diabetes mellitus and pre- diabetes were identified by fasting plasma glucose and OGTT. In this study, the cut-off points of fasting capillary blood glucose for detecting undiagnosed diabetes and pre-diabetes were evaluated, using receiver operator characteristic curve(ROC). Results Of 1351 subjects that having had oral glucose tolerance test, 230 cases were diagnosed as diabetes mellitus(7.3%), 166 cases(5.2%)as IFG, and 204(6.7%)as IGT under fasting capillary blood glucose as test variable and state variables according to the following criteria.(1)FPG≥7.0 mmol/L or/and 2hPG≥11.1 mmol/L(2)FPG<5.6 mmol/L (3)FPG<7.0 mmol/L and 7.8 mmol/L≤2hPG≤ 11.1 mmol/L, areas under three ROC curves were 0.905, 0.633 and 0.719, respectively. The cut-offvalues of screening for undiagnosed DM, IGT and IFG were 6.0 mmol/L, 5.7 mmol/L, and 5.7 mmol/L, respectively. When cut-off value of screening for undiagnosed DM was 6.0 mmol/L, the maximal sensitivity was 78.0% and specificity was 89.3%.But there were both lower sensitivity and specificity in screening for IFG and IGT according to the best predicting value(5.7 mmol/L)from the ROC curves(50.3% and 28.0% vs. 60.8% and 28.0%). Conclusion Fasting capillary blood glucose with the lower cut-point of 6.0 mmol/L in screening for undiagnosed diabetes mellitus alone, was relatively reliable, whereas for both IFG and IGT the fasting fingertip blood glucose tests were fallible. It was convenient and could be used in screening the DM at the community level.
