BACKGROUND: Serum uric acid level is associated with some chronic diseases and prognosis of severe infection. This study aimed to investigate the relationship between serum uric acid (SUA) and prognosis of infection in critically ill patients. METHODS: The data from 471 patients with infection admitted from January 2003 to April 2010 were analyzed retrospectively at Huashan Hospital Affiliated to Fudan University, Shanghai, China. The data of SUA, serum creatinine, blood urea nitrogen (BUN) and other relevant examinations within 24 hours after admission were recorded and the levels of SUA in those patients were described, then Student's t test was used to evaluate the relationship between SUA and pre-existing disorders. Different levels of SUA were graded for further analysis. The Chi-square test was used to examine the difference in the prognosis of infection. RESULTS: The mean initial level of SUA within 24 hours after admission was 0.232±0.131 mmol/L and the median was 0.199 mmol/L. Remarkable variations in the initial levels of SUA were observed in patients with pre-existing hypertension (t=–3.084,P=0.002), diabetes mellitus (t=–2.487, P=0.013), cerebral infarction (t=–3.061,P=0.002), renal insufficiency (t=–4.547,P<0.001), central nervous system infection (t=5.096,P<0.001) and trauma (t=2.875,P=0.004). SUA was linearly correlated with serum creatinine and BUN (F=159.470 and 165.059, respectively,P<0.001). No statistical correlation was found between the initial levels of SUA and prognosis of infection (χ2=60.892,P=0.100). CONCLUSION: The current study found no direct correlation between the initial levels of SUA after admission and prognosis of infection in critically ill patients.

The aim of this study was to investigate the circulating levels of IL-11 in the patients with chronic idiopathic thrombocytopenic purpura (CITP), and its significance, and to evaluate the curative effect of rhIL-11 on CITP. The level of IL-11 in patients with CITP was determined by ELISA before and after treatment, respectively. 1.5 mg of rhIL-11 were injected subcutaneously, once a day, continuously for 14 days as one course, treatment time 1 - 2 courses as total. The results showed that the higher blood IL-11 level was found in CITP patients than that in controls (P < 0.01) and during the course of treatment the number of platelets in peripheral blood of patients with CITP parallelled to the level of IL-11. The platelet counts were obviously increased in all CITP patients after rhIL-11 treatment. It is concluded that the serum level of IL-11 in patients is correlated to the number of platelets in patients. rhIL-11 can be used as an effective treatment for CITP.

OBJECTIVETo study the role of cerebrovascular hemodynamic indexes (CVHI) changing in stroke and to provide reference for stroke prevention and risk factor study.

METHODSFrom 2003 to 2004, participants aged 40 years and above in two communities in Fengxian district were recruited by cluster sampling. Risk factors of stroke and CVHI were investigated and checked during baseline investigation. A total of 10 565 individuals completed the survey and met the inclusion criterion. After baseline investigation, the cohort was followed up for stroke occurrence. Relative risk (RR) of CVHI and common risk factors were estimated by cohort study design.

RESULTSAge of the cohort was (56.2 ± 11.4) years. 4444 (42.1%) were males and 6121 (57.9%) were females. Total follow-up duration was 67 885.7 person-years. A total of 195 stroke cases occurred and incidence density of stroke was 287.2 per 100 000 person-years. Stroke incidence in exposure groups of hypertension, heart disease and alcohol drinking was 3.47% (108/3118), 2.96% (21/710) and 2.50% (47/1882), respectively. The incidence in corresponding non-exposure group was 1.17% (87/7448), 1.77% (174/9855) and 1.70% (148/8683) respectively. There was significant difference between 2 groups (χ(2) value was 62.72, 4.56 and 4.94, respectively, P < 0.05). Stroke incidence in CVHI score < 25, 25 - 49, 50 - 74 and ≥ 75 groups was 9.12% (59/647), 5.68% (44/775), 2.52% (39/1545) and 0.72% (53/7403)(χ(2)trend = 273.57, P < 0.05), respectively. Incidence of stroke in 40 - 49, 50 - 59, 60 - 69, ≥ 70 years age group was 0.22% (8/3565), 1.28% (43/3357), 2.71% (50/1848) and 5.88% (94/1600) (χ(2)trend = 181.48, P < 0.05), respectively. Multiple Cox regression analysis indicated that RR (95%CI) value of hypertension and cigarette smoking was 1.40(1.02 - 1.92) and 1.59(1.19 - 2.12), respectively when comparing with non-exposure group. RR (95%CI) value in CVHI score < 25, 25 - 49 and 50 - 74 points group were 6.15 (4.08 - 9.26), 4.55 (2.98 - 6.96) and 2.68 (1.75 - 4.09), respectively when comparing with the score ≥ 75 points group. RR (95%CI) value in age 50 - 59, 60 - 69 and ≥ 70 years group was 4.61 (2.16 - 9.82), 7.81 (3.67 - 16.60) and 13.49(6.44 - 28.24), respectively when comparing with below 40 years group.

CONCLUSIONCVHI score is the strong independent predictive factor and hypertension, cigarette smoking and age are the independent risk factors of stroke.

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.

Objective · To investigate the micro/ nano structure of human vaginal wall acellular matrix, and provide parameters for bionic vagina.Methods · A total of 35 vaginal specimens were obtained from 35 postmenopausal patients who underwent cystocele repair and/or rectocele repair.Cells in specimens were entirely removed, and the extracellular matrix was maintained. Then the acellular matrix was observed by general observation,H-E staining, Masson staining, scanning electron microscope and Micro-CT. The external and internal structure properties were measured and analyzed.Results · All cells in 35 vaginal specimens were totally removed. The vaginal wall acellular matrix was a double-layer fibrous reticular structure composed of interlaced collagen fibers, which were further arranged into bundles. Pores were distributed among fiber bundles. Epithelial side structure of vaginal wall acellular matrix was dense and subepithelial tissue was loose. There was no significant difference in fiber diameter [(82.4±9.3) nm vs (87.5±10.2)nm, P=0.432] and fiber bundle thickness [(67.6±9.3) μm vs (65.3±5.2) μm, P=0.634] between the dense and loose layers. Fiber bundle separation [(180.1±24.5) μm vs (118.2±23.0) μm, P=0.003] and total porosity [(77.1±4.2)% vs (66.6±2.8)%, P=0.002] were higher in loose layer. There was no significant difference in the micro/nano structure parameters of the acellular matrix between the anterior vaginal wall and the posterior vaginal wall.Conclusion · There was no significant difference in the fiber diameter and the fiber bundle thickness between the dense layer and the loose layer of vaginal wall acellular matrix, but the porosity of the dense layer fiber bundle was smaller than that of the loose layer.
