ABSTRACT
Objective@#To investigate the prevalence of hypertension among primary and middle school students living in Suzhou City, Jiangsu Province, so as to provide insights into comprehensive hypertension control among children and adolescents.@*Methods@# Primary and middle school students at ages of 7 to 17 years were recruited for a questionnaire survey in Suzhou City using the stratified cluster random sampling method from September to December, 2020, and the height and body weight were measured. Blood pressure was measured at three separate clinic visits according to the national criteria Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years ( WS/T 610-2018 ), and the detection of elevated blood pressure was estimated at three separate visits. In addition, factors affecting elevated blood pressure were identified. @*Results@#A total of 3 713 students were enrolled, including 1 924 boys ( 51.82% ) and 1 789 girls ( 48.18% ). The detection of elevated blood pressure was 13.63%, 5.36%, and 3.37% at three separate visits, respectively, and the prevalence of hypertension ( elevated blood pressure at all three visits ) was 3.37%. The detection rates of elevated blood pressure were all higher at three visits ( 16.90%, 8.40%, and 5.26% ) among students at ages of 12 to 17 years than among students at ages of 7 to 11 years ( 9.65%, 1.67%, and 1.07%, P<0.05 ). The detection of elevated blood pressure was significantly higher in boys ( 15.23% ) than in girls (11.91%) at the first visit ( P<0.05 ), while no significant differences were seen at the second or third visit ( P>0.05 ). In addition, higher detection rates of elevated blood pressure were seen in obese ( 27.62%, 11.51%, and 7.06% ) and overweight students ( 17.45%, 6.95%, and 4.85% ) than in students with normal weight ( 9.44%, 3.54%, and 2.15% ) at all three visits, and greater detection rates of elevated blood pressure were found in obese students than in overweight students at the first and second visits ( P<0.017 ).@*Conclusions @#The prevalence of hypertension was 3.37% based on three separate visits among primary and middle school students in Suzhou City. Measurement of blood pressure at three separate visits within different days is effective to reduce the false positive rate of hypertension and decrease misdiagnosis among children and adolescents.
ABSTRACT
Objective To explore the ability of waist circumference (WC) to predict hypertension risk in overweight and non-overweight middle school students in Suzhou. Methods The height, weight，WC and blood pressure values of 963 students from 8 middle schools in Suzhou were collected by a combination of questionnaire survey and physical examination. Logistic regression analysis was applied to explore the correlation between WC and high blood pressure in middle school students. Results Logistic regression analysis showed that before and after adjusting for confounding factors, for every 1 cm change in WC, the risk of high blood pressure increased to 1.08 (1.03-1.14) and 1.07 (1.02-1.13) for non-overweight students, and 1.05 (1.02-1.09) and 1.05 (1.01-1.08) for overweight students, respectively. Conclusion There was a positive correlation between WC and high blood pressure in both non-overweight and overweight middle school students in Suzhou. The risk of high blood pressure was higher for non-overweight students than overweight students for every 1 cm WC change. Targeted intervention measures should be taken to reduce the prevalence rates of hypertension for middle school students.
ABSTRACT
Q fever is a worldwide zoonosis and vaccination is the best measure to against its prevalence.Coxiella burnetii (Cb) is an obligate intracellular pathogen responsible for Q fever.Inactivated phase I Cb (Whole cell vaccine,WCV) can provide 100％ protection against Q fever,but its side effect of vaccination is strong.Phase I Cb is treated with chloroform-methanol or trichloroacetic acid and the chloroform-methanol residual (CMR) or the trichloroacetic acid extract (TCA) is used to substitute for WCV.Both CMR and TCA vaccine retain the protective efficient of WCV and significantly reduce the side effects.However,both CMR and TCA vaccine are required to isolate and purify Cb from chick embryos where Cb grows in a biosafety laboratory with the complex procedures.In recent 10 years,the scientists have investigated from protective antigens to CD4+ and CD8+ T cell epitopes of Cb,expecting that the genes encoding the T cell epitopes express highly and induce an efficient protection against Q fever in bodies.

ABSTRACT
Objective To know about knowledge about prevention and treatment of venous thromboembolism (VTE) in nurses from tertiary hospitals in China,and to analyze influencing factors to provide guidance for nursing of VTE. Methods A questionnaire survey was conducted among 5279 nurses from 80 tertiary hospitals in 29 provinces (municipalities,and autonomous regions). Results The average score of knowledge about VTE prevention and treatment in nurses was 61.26%. The knowledge was obviously unbalanced. Nurses had poor knowledge of elastic stockings and injection of prefilling anticoagulant drugs. The scores were high for nurses who were over 30 years old, had worked for more than 10 years, and had higher titles. Conclusion Currently knowledge about pre-vention and treatment of VTE in nurses in our country is not ideal,and there is imbalance in knowledge. Training is still an effective approach. There should be standardized training according to level of knowledge of nurses.

Objective To investigate the characteristics,occurrence times and management of cardiac erosion after transcatheter closure of ASD,and to discuss the mechanism and predictive factor of erosion.Methods We analyzed all the cases who received transcatheter ASD closure from September 1997 to September 2016 in our hospital retrospectively.Results 9 cases (9/6903,0.13％) were reported to have cardiac erosion events after device closure ASD of including 2 cases of acute cardiac tamponade needed pericardiocentesis,2 cases of aorta-to right-atrial fistula needed transcatheter closure or operative repair and 5 cases of perforation of the anterior leaflet of mitral valve.1 case with MV anterior leaflet perforation presented with hemolysis and required surgical repair.Cardiac erosion events were found at average 52.9±68.3 days (1-180days) after the ASD closure.Conclusions Cardiac erosion is a rare but serious complication of device closure for ASD.Erosion events are mostly attributed to device over-sizing or deficient retro-aortic rims.It is important for a strict follow-up,early deduction and timely disposition when an erosion event is identified.occurring.
ABSTRACT
Objective· To observe real-time changes of calcium concentration ([Ca2+]i) exposure to bilirubin in synaptosomes isolated from brainstem nucleus of rats. Methods · Forty P7-14 SD rats were randomly assigned to three groups: control group, bilirubin group (with levels of 0.1, 1 and 10 μmol/L) and bulirubin plus glycoursodeoxycholic acid (GUDCA) group. The synaptosomes were purified from brainstem nucleus by sucrose density gradient centrifugation. After loading OG-BAPTA in synaptosomes, two dimensional image of intracellular calcium and analysis of fluorescence intensity were achieved by Confocal laser scanning microscopy. Results · Synaptosomes with well biological activity were obtained from brainstem of the SD rats. In the control group, a progressive increase in fluorescent intensity of [Ca2+]I was detected. In the bilirubin group, acuter increases in fluorescent intensity were observed in all levels of bilirubin, with a manner of both concentration and time-dependent (P<0.05). Fluorescent intensity of [Ca2+]I was reduced in the present of GUDCA, which was not significant compared with the control group (P=0.656). However, GUDCA could abate the increase of fluorescent intensity of [Ca2+]I induced by bilirubin exposure, of which showing significant decrease in 10 μmol/L bilirubin exposure (P=0.000). Conclusion · Bilirubin could induce calcium overload in synaptosomes. GUDCA could abate bilirubin-induced calcium overload in synaptosomes, possibly explaining its protection effect of neurons from bilirubin neurotoxicity.

ABSTRACT
The safety and effectiveness of a novel Chinese one-shot dilation technique based on stimulated diuresis for percutaneous nephrolithotomy (PCNL) were investigated. After the feasibility of the Chinese one-shot dilation based on stimulated diuresis was verified by an animal study, this technique was applied in the clinical practice. A total of 67 patients in our department underwent the modified PCNL from July 2014 to June 2015. After the renal infundibulum was distended by stimulated diuresis, the kidney was punctured under the ultrasonographic guidance via the fornix of the target calyx. The working channel was dilated using a special designed pencil-shaped fascial dilator. The successful access rate, nephrostomy tract creation time, pre- and postoperative hemoglobin values and serum creatinine concentrations, stone-free rate and complications were recorded and analyzed. The renal infundibulum was successfully distended in all of the patients by the diuresis treatment. Under the ultrasonographic guidance, the successful access rate was 100% and the mean tract creation time was 2.0 min (range: 1.5-5.0 min). The stone-free rate right after surgery was 91.0%. Although the postoperative hemoglobin was significantly reduced (P<0.01), transfusion was not clinically necessary. There was no significant difference in serum creatinine concentrations before and after operation (P>0.05). No severe complication occurred during or after the PCNL. It was suggested that this Chinese one-shot dilation technique based on stimulated diuresis is an efficient and safe innovation for PCNL, and is even helpful for those patients with non-dilated pelvicaliceal systems.

Objective The aim of this study was to investigate the association between three single-nucleotide polymorphisms (SNP) of in the peroxisome proliferator-activated receptor (PPAR)α gene and the level of lipoprotein (a) [Lp (a)].Methods Participants were recruited under the framework of a cohort populations survey from the PMMJS (Prevention of Multiple Metabolic Disorders and MS in Jiangsu Province) which was conducted in the urban community of Jiangsu province from 1999 to 2007.644 subjects (234 males,410 females) were randomly selected and genotyped for three polymorphisms which were used as genetic marker for PPARα gene (rs 1800206,rs4253778 and rs135539).Data related to individual polymorphism and haplotype were available for analysis.x2 test was used to determine if the whole population was in Hardy-Weinberg genetic equilibrium.Linear regression models were used to analyze the association between SNPs in PPARα gene and the level of Lp(a).Associations between PPARα haplotypes and serum Lp(a) levels were analyzed by the SNPstats software.Results In the dominant model,after factors as sex,age,smoking,alcohol and BMI were adjusted,the presence of the V162 allele of L162V appeared associated with a high level of Lp(a) (mean difference was 57.70 mg/L(95％CI:32.03-83.37 mg/L),P＜0.001.Data from the haplotype analysis revealed that A-G-V and C-G-V haplotype (established by 1A＞C,7G＞C L162V) were significantly associated with a higher level of Lp(a) (P=0.012 0 and 0.009 7).Conclusion Results from our study might help to clarify the role ofPPARα gene in regulation of Lp (a) and the evaluation of its polymorphisms and haplotypes which were characterized as genetic factors for Lp (a).
ABSTRACT
The peroxisome proliferator-activated receptors [PPARs] -alpha, -delta/beta and -gamma are the ligand-activated tran-scription factors involved in the regulation of fatty acid and lipoprotein metabolism, energy balance, cell proliferation and differentiation and atherosclerosis, etc. We investigated the associations of 10 single-nucleotide polymorphisms [SNPs] in PPARs with apolipoprotein [apo] A-I/ apoB ratio in Chinese Han population. Overall, 630 subjects [212 males, 418 females] were randomly selected from the Prevention of Metabolic Syndrome and Multiple Metabolic Disorders in Jiangsu Province of China Study Cohort. Population analyzed was as the general population which involved healthy people and individuals with disorders of apoA-I or apoB. 10 SNPs [rs1800206, rs135539, rs4253778, rs2016520, rs9794, rs10865710, rs1805192, rs709158, rs3856806 and rs4684847] were genotyped. Mean difference [Difference] and 95% confident interval [95%CI] were calculated. After covariates adjustment, rs1800206-V allele [LV+VV] and rs3856806-T allele [CT+TT] were significantly associated with a decreased apoA-I/ apoB ratio than those wild type carriers, Difference [95%CI] were -1.29[-1.96 tilde -0.62]and -0.8 [-1.42 tilde -0.17], respectively. Rs4253778-C allele was significantly associated with an increased apoA-I/ apoB ratio compared to the wild type carriers [GG], Difference [95%CI] was 0.76 [0.04 tilde 1.48]. Generalized multifactor dimensionality reduction analysis showed that three-to-eight-locus models were significant with apoA-I/ apoB ratio [P<0.05]. We chose the seven-locus model [P=0.0010] as the best GMDR model [cross-validation consistency was 7/10 and testing accuracy was 62.97%]. Our data provided the evidence that PPARs polymorphisms might be involved in regulation of apoA-I/ apoB ratio in independently and/or in an interactive manner
