Objective To investigate the association of serum uric acid level with glomerular filtration rate and explore the predictive value of the physiological uric acid levels for reduced renal function.Methods A total of 6 532 subjects from Karemary community and 2 402 subjects from the First Affiliated Hospital of Xinjiang Medical University were enrolled.All subjects were surveyed with questionnaire and their serum biochemical indices and liver functions were measured.Meanwhile,a cohort study was conducted,752 subjects with normal renal function were selected from young and middle-aged healthy people in 2008.During the 3-year follow-up,the incidence of reduced renal function and the risk factors of estimated glomerular filtration rate (eGFR) were analyzed.Results Serum uric acid (SUA) was the independent risk factor of reduced GFR in cross-sectional analysis.The 2 groups were stratified by sex and age,except for female population over 45 years old in the first group,the level of physiological serum uric acid was the risk factor for decreased eGFR in the rest of groups.During 3-year follow-up,the incidence of reduced renal function was 15.40％ and SUA was the independent risk factor of decreased eGFR.Conclusions The concentration of physiological serum uric acid was closely related with renal function,and the increase in SUA whthin normal range had an important early predictive value for decreased GFR.

Objective To explore the association of serum uric acid level with non-alcoholic fatty liver disease(NAFLD) in Han and Uyghur ethnic groups.Methods A cross-sectional study was performed in the population in 2011 in the First Affiliated Hospital of Xinjiang Medical University.The study included 2439 Uyghurs and 2285 Hans with a questionnaire survey,and body mass index (BMI),waist circumference,blood pressure,blood glucose,blood lipid,and serum uric acid (SUA) level were measured.The participants were divided into 4 groups according to the quartiles of the SUA levels within the normal range,and those with SUA levels above the normal range served as hyperuricemia group.The associations between serum uric acid level and prevalence of non-alcoholic fatty liver,hyperuricemia,and metabolic syndrome (MS,including each component of MS) were analyzed.Results Among Uyghurs and Hans,the detection rates of NAFLD were 26.7％ and 23.6％ respectively,the detection rates of hyperuricemia were 7.8％ and 18.2％,and the level of serum uric acid in Uyghur group was lower than that in Han group (P＜0.01).The detection rate of NAFLD in the hyperuricemia patients was significantly higher than that in nonhyperuricemia group.Among the Uyghurs and Hans,the detection rates of NAFLD in the hyperuricenia patients were 24.0％ and 19.9％.The detection rate of NAFLD was positively associated with concentration of serum acid even that within the normal range.Conclusion The relationship between the level of serum uric acid and the prevalence of NAFLD is more evident in Uyghur than that in Han.

Objective: To observe the migration of 4,4＇-diaminostilbene-2,2＇-disulfonc acid-based fluorescent whitening agents ( DSD-FWAs ) in food packaging paper, so as to provide evidence for quality and safety supervision for paper packaging materials. Methods: Forty-one paper samples with DSD-FWAs positive were made into 6 cm2 pieces and were soaked in four food simulants ( distilled water, 3% acetic acid, 10% ethanol and 95% ethanol, 10 mL each ). The experiment was carried out at the specified soaking temperature and time. The migration amounts of eleven DSD-FWAs were detected by high performance liquid chromatography-fluorescence detection. Results: C.I.220, C.I.24, C.I.210, C.I.85, C.I.113, C.I.264, C.I.353 and C.I.357 were found in all the four food simulants. At the same time and temperature, the migration amount was highest in 10% ethanol, followed by distilled water, 3% acetic acid and 95% ethanol. C.I.220 was dissolved in all four food simulants, in the range of 20-90 ℃, the migration amount increased with soaking temperature; at 20 ℃, 40 ℃ and 60 ℃, the migration amount increased first and then stabilized over time. Conclusion The higher the storage temperature and the longer the storage time of paper packaging, the easier the DSD-FWAs in packaging paper migrate to food.

Objective:To investigate the feasibility of using anastomotic stoma as a long-term vascular access to maintain hemodialysis in patients who cannot establish an effective vascular access after ACUSEAL graft occlusion.Methods:A rare case of brachial artery-right atrium ACUSEAL artificial blood vessel fistula bypass to establish vascular access occlusion, the use of artificial blood vessel anastomosis stoma to establish buttonhole puncture as a long-term vascular access and the corresponding nursing methods.Results:At present, the patients were treated with regular dialysis for 32 months and blunt needle puncture for 23 months.Conclusions:Brachial artery-right atrium ACUSEAL graft is a rare vascular access surgery. As a new type of access with depleted autologous vascular resources, the efficacy is not certain. Because it is different from the traditional vascular prosthesis surgery, once the thrombotic occlusion of the graft fails, the risk and difficulty of reopening by interventional or surgical methods are great. Therefore, it is a challenging and reasonable method to use the limited residual cavity of the anastomosis as a long-term vascular access after occlusion to prolong the service life of the graft.

AIM:To observe the effects and mechanisms of hydroxyethylstarch (HES) 130/0.4 on no-reflow phenomenon after myocardial ischemia-reperfusion in rats.METHODS: SD rats were randomly divided into 4 groups:sham operation group , ischemia-reperfusion ( IR, treated with normal saline ) group, normal saline ischemia-reperfusion (NS-IR, treated with NS) group and HES ischemia-reperfusion (HES-IR, treated with HES) group.Myocardial infarct size and no-reflow range were determined by staining methods , and the activities of myocardial enzymes ( CK-MB, cTnI and MPO) were measured .Meanwhile , cardiac microvascular endothelial cells of the rat were cultured and divided into 4 groups:control group, hypoxia/reoxygenation (H/R) group, NS-H/R group and HES-H/R group.Acute ischemia reper-fusion models were simulated , and the concentration of calcium ions was measured .The relative cell activity was evaluated by CCK-8 assay, and the apoptotic rate was detected by flow cytometry .RESULTS:In HES-IR group, the myocardial in-farct size, the no-reflow zone, CK-MB, cTnI and MPO activity were all significantly lower than those in IR group ( P<0.05).In microvascular endothelial cells , the concentration of calcium ions and the apoptotic rate in HES-H/R group were significantly decreased, while the relative cell activity increased compared with H/R group (P<0.05).CONCLUSION:HES reduces no-reflow in acute myocardial ischemia-reperfusion .The mechanism may be involved in the inhibition of both the infiltration of neutrophils and the calcium overload of endothelial cells .

OBJECTIVETo analyze the relationships between smooth-muscle tumors of gastrointestinal (GI) tract and gastrointestinal stromal tumors (GISTs), and the efficacy of surgical management.

METHODSThe clinical and pathological data of 135 cases of GISTs were collected, including cases of leiomyomas/leiomyosarcoma between 1993 and 2003 and GIST between Jan. 2000 and Jul. 2005. The surgical outcomes were analyzed retrospectively.

RESULTS82.1% of former leiomyomas/leiomyosarcomas was corrected to GISTs. Overall 5-year survival rate was 79.7%. Univariate analysis revealed preoperative metastasis, tumor size, mitotic index, and postoperative metastasis or recurrence were correlated with overall survival in patients with completed resection. Multivariate analysis showed that only postoperative metastasis or recurrence were the indicators of poor prognosis, but without statistical significance (P=0.064). However, multivariate analysis for disease-free survival showed that preoperative metastasis and mitotic index were two independent predictors of poor prognosis (P=0.001 and P<0.001).

CONCLUSIONSMost former leiomyomas/leiomyosarcomas of GI tract should be corrected to the diagnosis of GISTs. Complete surgical resection is the choice of treatment for GISTs. Preoperative metastasis and mitotic index are two independent predictors of poor prognosis.

OBJECTIVETo observe clinical curative effect of cake-separated moxibustion on impaired glucose regulation (IGR) and explore its action mechanism.

METHODSSixty cases were randomly divided into a simple lifestyle intervention group (control group) and a cake-separated moxibustion combined with lifestyle intervention group (observation group), 30 cases in each one. The control group was treated with lifestyle intervention. Based on lifestyle intervention, cake-separated moxibustion at Pishu (BL 20), Weishu (BL 21) and Yishu (EX-B 3) was applied to the observation group. Fast plasma glucose (FPG), two hours plasma glucose after oral glucose tolerance test (OGTT2hPG), fasting insulin (FINS), homa insulin resistance index (HOMA-IR), blood lipid, body mass index (BMI) and waist circumference (WC) were observed in the two groups before and after treatment.

RESULTSAfter treatment, the OGTT2hPG and FPG were both decreased significantly (both P<0.05) in the two groups, compared between the two groups, the differences of FPG [(0.41 +/- 0.42) mmol/L vs (0.05 +/- 0.08)mmol/L] and OGTT2hPG [(0.85 +/- 0.53)mmol/L vs (0.17 +/- 0.19)mmol/L] were both statistically significant. There were no significant changes in FINS, HOMA-IR, blood lipid, BMI and WC in the control group before and after treatment (all P>0.05), but FINS, HOMA-IR levels, triglycerides (TG), total cholest-erol (TC), low density lipoprotein (LDL-C), BMI and WC in the observation group were decreased obviously after treatment (all P<0.05), which had statistical differences between the two groups (all P<0.05).

CONCLUSIONThe cake-separated moxibustion combined with lifestyle intervention can obviously control blood glucose levels, improve insulin resistance and blood lipid levels, decrease BMI and WC.
