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.

Objective To analyze urine volume and dietary salt intake assessed by two 24 h urine specimens，to discuss its application value for evaluating population level and individual level dietary salt intake． Methods The subjects aged 18-69 years were selected from four counties in Shandong Province and Jiangsu Province from 2013 to 2014 by using multi-stage stratified cluster random sampling method． A questionnaire survey was conducted and two 24 h urine with an interval of one day were collected． The differences between two 24 h urine volume，and the dietary salt intake between two 24 h urine were assessed at individual level and population level． Ｒesults A total of 1 288 subjects was( 42．3± 14．0) years old，of which 626( 48．6%) were males． The average urine volume of the subjects was ( 1 462±437) ml． The first 24 h urine volume ( 1 427±488) ml was lower than the second 24 h urine volume ( 1 498± 552) ml ( t = -4．439，P＜0．001) ． The dietary salt intake was ( 9．8±3．3) g，and the dietary salt intake of males ( 10．1±3．5) g was higher than that of females ( 9．5±3．1) g ( t = 3．09，P= 0．002) ． There was a significant difference in dietary salt intake among different age groups ( F= 7．57，P＜0．001) ． The dietary saltintake of 1 136 ( 88．2%) subjects was higher than the recommended level． At the individual level，the participants with the absolute difference with 1g between the subjects’two 24 h urinary salt excretion was 279 ( 21．7%) ，and the participants with the absolute difference with ＞3 g was 48．5%． At the population level，the first 24 h urinary salt excretions ( 9．9 ± 4．1) g was similar to that in the second 24 h urine and ( 9．7±4．0) g ( P= 0．1021) ． The intraclass correlation coefficients between salt excretions in the two 24 h urine was 0．508( 95% CI: 0．451-0．559) ． Conclusion The results of this study suggest that 24 h urinary salt excretion can better assess the salt intake at population level，but cannot accurately reflect the individual’s salt intake．

AIMTo explore the effects of calcitonin-gene-related peptide (CGRP) on LPS-induced MMP-9 secretion by alveolar macrophages (AM) in vitro.

METHODSThe supernatant of LPS-induced Wistar rat AM from different intervention groups were collected to measure the activity by gelatin zymography.

RESULTS(Only secreting a small amount of MMP-9 with unstimulated AM, LPS stimulated MMP-9 production in a concentration-dependent manner (p < 0.01). (2) The activity of MMP-9 in CGRP intervention groups at different levels were significantly lower than those in non-intervention group (p < 0.01). (3) The inhibiting effects of CGRP were diminished by H-7 and W-7, an antagonist of protein kinase C (PKC) and calmodulin (CaM) (p < 0.05).

CONCLUSIONThese data suggested that CGRP involved in the MMP-9 secretion by AM, partly, via PKC and CaM pathway.

To evaluate the use of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) for treatment of acute and chronic leukemia, from March 1997 to January 2003, 21 adult patients with malignant hematopoietic diseases underwent allo-PBSCT from HLA-identical siblings (19 patients) and haplo-identical mother (one) and one B point site mismatched sibling (one). All donors were mobilized with G-CSF for 4 days and peripheral blood stem cells were collected by CS-3000 separator. The conditioning regimen included the high dose combination chemotherapy and TBI. Cyclosporine-A (CsA) plus a short course of MTX was used for GVHD prophylaxis in all patients. The results showed that after trans plantation, median time for the recovery of granuocyte > or = 0.5 x 10(9)/L and platelets > or = 20 x 10(9)/L were 12 (10 - 20) and 15 (11 - 35) days, respectively. Acute GVHD was observed in 8/17 patients (47%), of which one transplanted from HLA-haploidentical mother. Chronic GVHD occurred in 12/17 patients (70%). All of four female survivals did not show acute and chronic GVHD. Day 100 transplantation-related mortality was 14% (3/21). Relapse occurred in two patients (9.5%) who underwent allo-PBSCT in stage of non-remission at one and six months. After follow-up of 40 (15 - 70) months, 11 patients (52.4%) are still disease-free survival. These results suggested that peripheral blood stem cells produce a faster hematopoietic recovery and a lower relapse of leukemia. The rate of aGVHD is not increased when using the peripheral blood as source of stem cells; however, cGVHD continues to be a significant problem. Donors tolerated the procurement procedure without complications.

OBJECTIVETo analyse the heritabilities of physical growth items of body and its related factors.

METHODSAn 116 twin pairs of Han nationality, 67 monozygotic (MZ) and 49 like-sex dizygotic (DZ) aged 6 to 12 years, were investigated from June to October in 2004. The measurements included height, weight, sitting height, chest circumference, biacromial breadth and biiliac breadth, and BMI index calculated by the former two measurements. The heritabilities were estimated by using intraclass correlation coefficient method from the adjusted data for age.

RESULTSThe intraclass correlation coefficient was greater in the MZ twins than in the DZ twins. The estimated heritabilities of height, weight, BMI, sitting height, chest circumference, biacromial breadth and biiliac breadth were 0.89, 0.88, 0.73, 0.87, 0.78, 0.78, 0.73 in boys and 0.87, 0.74, 0.72, 0.86, 0.62, 0.56, 0.59 in girls adjusted for age. Therefore, there were no sex difference for the heritabilities of height, sitting height and BMI, but the male heritabilities of weight, chest circumference, biacromial breadth and biiliac breadth were higher than the female's respectively.

CONCLUSIONPhysical growth items should be mainly determined by the genetic factors. There are sex differences for the heritabilities of weight, chest circumference, biacromial breadth and biiliac breadth, i.e., the girls might be affected more easily by environmental factors than the boys in these items.

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.
