Objective To analyze the association between 24-hour urinary sodium excretion and obesity in a general Chinese population aged from 18 to 69 years old. Methods 2 400 from 18 to 69 year-old subjects were selected from four counties in Shandong Province and Jiangsu Province from 2013 to 2014 by using multi-stage stratified cluster random sampling method. Questionnaire survey, physical measurement and 24-hour urine collection were conducted. The relationship between urinary sodium and obesity was analyzed by multivariate linear regression and Logistic regression analysis. Results 2 275 subjects were finally included in the analysis. Obesity rate of the subjects was 19.1%(95% CI:17.4%-20.6%)and 24-hour urinary sodium was (166.4±71.5) mmol/d. The urinary sodium in obese, and central obesity population calculated according to waist-to-height ratio (WHtR) were higher than the normal population, respectively (All P<0.05). Multivariate linear regression analysis showed that after adjusting for relevant factors, 24-hour urinary sodium was positively correlated with body mass index (BMI), waist circumference (WC) and WHtR. Multivariate Logistic regression analysis showed that compared to population in the lowest quantile, population in highest quantile had an increased risk of being the obesity, abdominal obesity(calculated according to WC) and abdominal obesity(calculated according to WHtR) with OR(95% CI) of 1.61(1.18-2.20), 2.01(1.39-2.89) and 1.47(1.15-1.89), respectively, after adjusting for age, gender, education, smoking, alcohol consumption, physical activity, hypertension and diabetes. Conclusions High sodium is independently associated with obesity. Sodium intake is a potential and important risk factor for obesity.

OBJECTIVETo explore the relationship between systemic inflammatory response syndrome(SIRS) and severity of acute pancreatitis combined with plateau erythrocythemia in the high altitude.

METHODSA retrospective analysis on the clinical data which involved acute pancreatitis combined with plateau erythrocythemia (n = 40) and without plateau erythrocythemia (n = 40) admitted from September 2006 to September 2009 was conducted. According to the unified standards, these cases were divided into plateau erythrocythemia group and no plateau erythrocythemia group. The patients in plateau erythrocythemia group were further divided into severe group and mild group according to scores of APACHEII. The data was analyzed according to the patient with (or without) SIRS, SIRS's standard indicators, diagnostic parameter and relation of severity and duration of SIRS in acute pancreatitis combined with plateau erythrocythemia.

RESULTSThere was significantly discrepancy between plateau erythrocythemia group and no plateau erythrocythemia group not only in the incidence of patients who developed SIRS, but also in two items of patients fulfilling or not fulfilling diagnostic criteria of SIRS (P < 0.05). There was significant statistical difference in three items of diagnostic parameter of SIRS between plateau erythrocythemia group and no plateau erythrocythemia group (P < 0.05). Significant difference in two and three diagnostic parameter was found on severity of SIRS in acute pancreatitis combined with plateau erythrocythemia (P < 0.05). The more severity acute pancreatitis combined with plateau erythrocythemia was, the longer duration of SIRS was.

CONCLUSIONSIRS is highly correlated with the severity of SIRS in acute pancreatitis combined with plateau erythrocythemia in the high altitude.

OBJECTIVETo investigate the effects of dopamine and norepinephrine on the renal function in the patients with septic shock.

METHODSEighty-seven patients with septic shock were divided into three groups (group A, B, C) according to the biggest infusing rate of norepinephrine, with the infusing rate of 0.5 - 0.9, 1.0 - 1.5, 1.6 - 2.0 microg x kg(-1) x min(-1), respectively. Mean arterial blood pressure (MAP), heart rate (HR), urine output, blood urea nitrogen (BUN), creatinine (CRE), urine albumin (U-ALB) and urine beta(2)-microglobulin (Ubeta(2)-MG) as well as APACHE III score in all the patients were detected.

RESULTSBefore anti-shock therapy was given, hypotension, tachycardia and oliguria occurred in all the 87 patients, and CRE, BUN, U-ALB, Ubeta(2)-MG and APACHE III score were abnormal in most cases. With the anti-shock therapy, MAP, HR, urine output and BUN, CRE in all patients returned to normal levels gradually, and U-ALB, Ubeta(2)-MG levels and APACHE III score also restored but still remained abnormal.

CONCLUSIONSThe first aim of treating septic shock should be restoring the organ blood supply, and based on volume resuscitation, dopamine, noradrenaline and other vasoactive drugs could be combined to maintain circulatory stability.

OBJECTIVETo evaluate the value of deep small-bowel endoscopy (DSBE) in the diagnosis of Crohns disease (CD).

METHODSThe endoscopic and clinical data of 54 patients with CD receiving capsule endoscopy (CE) and double-balloon enteroscopy (DBE) between January, 2004 and December, 2008 were summarized and analyzed retrospectively.

RESULTSThe main indications for DSBE in our series were suspected CD (42.6%) and obscure gastrointestinal bleeding (25.9%). DSBE was obviously superior to barium imaging. The detection rate of CD was significantly higher with DSBE (92.6%) than with ileocolonoscopy (75.9%, P=0.017), and DSBE provides much more detailed descriptions of specific endoscopic features such as segmental distribution and lumen changes. DSBE significantly improve the diagnostic efficiency, giving priority to offer a guide and raise suspected diagnosis for CD.

CONCLUSIONDSBE is a valuable modality for detecting CD lesions in the jejunum and ileum and for evaluating lesion involvement and severity. The combination with a comprehensive analysis of routine imaging findings, gastro endoscopy, and clinical data can further enhance the diagnostic efficiency of DSBE.

OBJECTIVETo identify the relationship of body mass index (BMI) and blood pressure in 7 - 15 years children and adolescents of Beijing so as to provide scientific basis for early prevention of hypertension and to provide evidence for verification on the category criterion of overweight and obesity in children and adolescents of China, recommended by the Working Group on Obesity in China (WGOC) to sensitively distinguish the blood pressure in normal weight, overweight and obesity populations.

METHODSA cross-sectional survey on epidemiological characteristics of obesity with stratified cluster sampling method carried out in Beijing in April and May, 2000. 5155 students aged 6 - 15 years were selecte das research subjects. The category criterion of overweight and obesity in children and adolescents of China was recommended by WGOC, the diagnostic criterion of hypertension in children was recommended by CDC in the USA. Statistics analysis system (SAS 8.1) including partial person correlation analysis, t-test, chi(2) test and logistic multi-factors regression analysis was used to analyses the data from 4982 subjects aged 7 - 15 years.

RESULTS(1) after the age and gender were adjusted, the BMI positive correlation with systolic blood pressure (SBP) and diastolic blood pressure (DBP) was found independent in 7 - 15 years children and adolescents (P < 0.0001) and the partial relation coefficients(r) between BMI and SBP and DBP were 0.323 87 and 0.245 88 respectively. (2) the means of SBP and DBP in obesity group were significantly higher then overweight, while overweight was significantly higher then normal weight group (P < 0.0001). (3) the prevalence rates of hyper-SBP, hyper-DBP and hypertension were significantly different (P < 0.0001). When compared with the normal weight group, the relation risk (RR) for hypertension in overweight group and obesity group were 2.96 and 4.85 respectively. The prevalence rates of hypertension in overweight and obesity group were 19.70% and 24.22% respectively. (4) the results of logistic multi-factors regression analysis showed that both age and weight were effecting on hyper-SBP, hyper-DBP and hypertension (P < 0.0001). After age was adjusted, the RR for hypertension was 2.62, and their confidence interval (CI) was 2.36 - 2.91 in obesity or overweight, between overweight and normal weight.

CONCLUSION(1) the BMI positive correlation with SBP and DBP was found independent in 7 - 15 years children and adolescents of Beijing, and the risk for hypertension maybe increased when these people with overweight and obesity, it is very important for hypertension prevention and control that overweight and obesity prevention and control in children and adolescents. (2) the sensitivity of the category criterion of overweight and obesity in children and adolescents of China, recommended by WGOC have been verified on distinguish the blood pressure in normal weight, overweight and obesity populations.
