Four-stage selected random samples were used to analyze the prevalence and distributing feature of hyperuricemia and gout in 13 559 Han,Uighur,and Hazakh adults in Xinjiang. The prevalence of hyperuricemia was 11.00%,3.27%,and 3.94% respectively in Han,Uighur,and Hazakh populations,and 1.32%, 0.65%,and 0.70% for gout,with statistically significant difference among three groups(all P＜0.05). No-conditional logistic regression analysis showed that nationality,body mass index,renal function,and serum lipid were risk factors of hyperuricemia,while female and physical activity were protective factors. Eating seafood and animal visceral organs were independent risk factors of hyperuricemia in Han population. Eating animal visceral organs and drinking alcohol were independent risk factors of hyperuricemia in Hazakh population.

Objective To observe the influence of either alone or combined mixed-tocopherols combined with eicosapentaenoic acid (EPA) and α-Tocopherol use on oxidized LDL (oxLDL) induced 8-hydroxy-2'-deoxyguanosine (8-OHDG) and interleukin-6 (IL-6) secretion by human umbilical vein endothelial cells(HUVECs) and to explore the potential mechanism. Method Cultured HUVECs in vitro were incubated with oxLDL, oxLDL + α-tocopherol, oxLDL + mixed-tocopherols, oxLDL + EPA, oxLDL + α-tocopherol + EPA, oxLDL + mixed-tocopherols + EPA for 24 hours, respectively. Secretion of 8-OHDG and IL-6 were detected by cell enzyme linked immunosorbent assay (ELISA). The expressions of superoxide dismutase (SOD), protein kinase C-δ (PKC-δ), phosphorylated PKC-δ (p-PKC-δ) were analyzed by Western blot. Results 8-OHDG and IL-6 secretion of HUVECs was significantly increased significantly after incubated with oxLDL for 24 hours which could be significantly attenuated in the presence of tocopherols and EPA ( alone or in combination, all P ＜ 0. 05 ) while the strongest inhibition effects were seen with combined use of mixed-tocopherols and EPA. Moreover, combination of mixed-tocopherols and EPA could also significantly increase SOD activity and decrease PKC activity (all P ＜ 0. 05 ). However, the protein expression of SOD and PKC-was similar among groups. Conclusion Combined mixed-tocopherols + EPA use enhanced the inhibiting effects on the secretion of 8-OHDG and IL-6 in oxLDL stimulated HUVECs which might be linked with increased SOD activity and reduced p-PKC activity.

Objective To investigate the relationship between hemoglobin and blood pressure of pregnant women in Zhoushan islands, so as to provide scientific evidence for the etiological study of gestational hypertension. Methods A retrospective study was conducted among 1 383 pregnant women who received perinatal care in Zhoushan Maternal and Child Health Hospital of Zhejiang Province from January 2017 to June 2018. Pregnant women were monitored for hemoglobin content and blood pressure in the early, middle and late pregnancy. The multivariate linear regression was used to analyze the relationship between hemoglobin content and blood pressure in different pregnancy. Results The incidence of anemia in early, middle and late pregnancy was 7.74%, 25.45% and 15.76% respectively. The multivariate linear regression showed that hemoglobin levels during pregnancy had effects on systolic blood pressure in early, middle and late pregnancy, and the earlier hemoglobin levels were monitored, the more obvious the effect on systolic blood pressure was.With the increase of hemoglobin level, systolic blood pressure increased, such as the effect of hemoglobin on systolic blood pressure in early pregnancy, mid-pregnancy and late pregnancy. Hemoglobin of first trimster had the greatest effect (β=0.10, P<0.001), Hemoglobin of second trimester had no obvious effect, and that of third trimester had the second effect (β=0.04, P=0.027).Hemoglobin levels and diastolic blood pressure levels were similar to their relationship with systolic blood pressure. Conclusions Hemoglobin levels during pregnancy have significant effects on systolic and diastolic blood pressure in first, second and third trimsters of pregnancy. Regular measurement of hemoglobin levels during pregnancy can improve the health of pregnant women.

Objective To study the correlation between renal function and arterial stiffness of Uighur population over 35 years old in Xinjiang area. Methods From October 2007 to March 2010, four-stage stratified random sampling method was applied to collect a total of 4312 Uighur people over 35 years old in Urumqi, Karamay, Fukang, Turpan area, Hotan prefecture, Yili Kazak autonomous prefecture and Altai prefecture. The data of these 4312 general urban and rural Uygur residents were complete. Simplified MDRD formula was used to calculate the estimate glomerular filtration rate (eGFR). Arm-ankle pulse wave velocity (b-aPWV) of both sides was measured and the average value was used in correlation analysis with eCFR, and then the associated risk factors were adjusted. Results The eGFR was negatively correlated with b-aPWV (r=-0.174, P<0.01). Multiple linear regression showed that after adjusting some risk factors such as age, sex, body mass index, systolic blood pressure, diastolic blood pressure, waist circumference, hip circumference, uric acid, fasting blood glucose, total cholesterol, triglycerides, low density lipoprotein, eGFR was still negatively correlated with b-aPWV (P=0.012). Conclusions In Uygur population over 35 years old in Xinjiang, the glomerular filtration rate is negatively correlated with arterial stiffness.

BACKGROUNDBiofilms have given new insights to the understanding of pathogenesis of chronic rhinosinusitis (CRS). However, the link between biofilms formation and local inflammatory response remains poorly defined in CRS with nasal polys. The aim of this study was to determine the potential association of the presence of biofilms in the nasal mucosal tissues with clinical features in Chinese patients, which had CRS with nasal polyps (CRSwNP).

METHODSA total of 19 patients with CRSwNP and 12 patients with non-CRS were subjected to endoscopic surgery and their nasal mucosal tissue specimens were examined histologically and by scanning electron microscopy (SEM). Their demographic and clinical features were recorded.

RESULTSThirteen (68.4%) out of the 19 specimens from patients with CRSwNP, but none from control patients, were positive for biofilms that displayed typical characteristics of bacterial and fugal structures. The presence of biofilms in the nasal mucosal tissues was associated with significantly greater values of purulent nasal discharge and preoperative Lund-Kennedy scores, higher levels of serum total IgE and percentages of subjects with endoscopic surgery (ESS) history in patients with CRSwNP, and more severe inflammation in the nasal mucosal tissues of patients with CRSwNP.

CONCLUSIONOur study demonstrated the presence of biofilms in the nasal mucosal tissues of many patients, contributing to the understanding of the pathogenic process of CRSwNP in Chinese patients.

The structural modification of nano-micellar polymer carriers can not only increase the solubilization of insoluble drugs, but also make drug-loaded carriers aggregate in tumor tissues. In this paper, paclitaxel (PTX) was used as a model drug, D-α-tocopherol polyethyleneglycol 1 000 succinate (TPGS) modified by disulfide bond (-S-S-) and oleic acid (OA) was synthesized and mixed micelles were prepared with different molar ratios of sodium deoxycholate (NADC), and TPGS and NADC mixed micelles modified by thioether bond were synthesized for comparative study. The effects of the critical micelle concentration (CMC) of the modified polymer and the molar ratio of TPGS-OA and NADC on the physical and chemical properties of the micelle were investigated. Finally, the redox drug release ability of disulfide bond and thioether bond was compared. The results showed that when the molar ratio of TPGS-OA to NADC decreased, the drug loading increased, but the stability decreased. When the molar ratio was 3∶1, the particle size, potential and entrapment efficiency of TPGS-S-S-OA/NADC were 96.24 ± 0.14 nm, -24.4 mV and (98.7 ± 0.08)%, respectively, hemolysis rate of mixed micelles is less than 2%. The disulfide modified mixed micelles released PTX completely within 5 h in 10 mmol·L^-1 H₂O₂ environment (pH 7.4), which was similar to that of thioether modified micelles. It was also found that the stability of micelles decreased when the pH value was low. All animal experiments were in accordance with ethical standards and were approved by the Animal Experimental Center of Shenyang Pharmaceutical University (No.211002300032403). In this study, we mainly developed stable nano-micelle carriers which can target drug release in tumor heterogeneous environment.

Objective To investigate the prevalence and major risk factors of peripartum thromboembolic disease in different regions of Guangdong province.Methods Data from 169 218pregnant women in different regions of Guangdong province from January 2005 to June 2010 were analyzed retrospectively.The prevalence and epidemiological characteristics of thromboembolic disease during pregnancy or puerperium were investigated.Results Of the studied population,( 1 )20 l cases ( 1.3‰ ) suffered from thromboembolic disease during pregnancy or puerperium including 128 cases of deep vein thrombosis (DVT),68 cases of cerebral venous thrombosis (CVT) and 5pulmonary embolism,the prevalence rates were 0.8‰,0.4‰,and 0.02‰ respectively.(2) Risk factors in different regions showed that,in the Pearl River Delta area,the major risk factors for DVT would include previous or family history of thrombosis,pregnancy complications,with medically involved diseases,prolonged bed rest and pregnancy weight gain ＞ 15 kg etc.While in castern,western,northern parts of Guangdong,the major risk factors for DVT would include pregnancy weight gain ＞ 15 kg,prolonged bed rest,preeclampsia,cesarean section and complications during pregnancy.In Pearl River Delta region,the major risk factors for CVT would include eclampsia,preeclampsia,pregnancy complications,prolonged bed rest ＞3 days,past history or family history of thrombosis.While eclampsia,preeclampsia,advanced age or younger age,pregnancy weight gain ＞15 kg,complications during pregnancy were the major risk factors for CVT in the eastern,western or northem parts of Guangdong.Conclusion Prevalence and major risk factors of peripartum thromboembolic disease in different regions of Guangdong were different.It was crucial to take effective measures in pregnant women with different epidemiological characteristics and risk factors to prevent and reduce the incidence of peripartum thromboembolic disease.

OBJECTIVETo investigate the effect of ulinastatin, a urinary trypsin inhibitor, on the postoperative liver function in patients who have received bilateral total knee arthroplasty (TKA) under pneumatic tourniquet.

METHODSTotally 40 patients who were scheduled to receive bilateral TKA under thigh tourniquet were randomly assigned into trial group (U group, receiving intravenous ulinastatin) and control group (C group, receiving natural saline). All patients received the same general anesthesia and postoperative analgesia. The plasma concentrations of alanine transaminase (ALT), total bilirubin (TBil), and direct bilirubin (DBil) were recorded and compared preoperatively and 4, 24, 48, and 72 hours after the surgery.

RESULTSThe demographic data were not significantly different between these two groups (P>0.05). The ALT was not significantly changed after the surgery in the C group (P>0.05) but was significantly decreased 48 hours (P=0.002) and 72 hours (P=0.001) after the surgery in the U group. TBil and DBil were significantly increased 48 hours (P=0.012, P=0.000) and 72 hours (P=0.000, P=0.000) after the surgery in C group, while only that at 48 hours (P=0.010, P=0.038) was significantly increased in the U group. ALT 4 hours (P=0.026), 48 hours (P=0.013), 72 hours (P=0.004) after the surgery were significantly lower in the U group than those in C group. TBil at the 72 hours postoperatively in U group was significantly lower than that in C group (P=0.036). DBil was not significantly different between C group and U group at all time points (all P>0.05).

CONCLUSIONThe application of ulinastatin in bilateral TKA can protect postoperative liver function.
