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.

Medium- and long-chain triglyceride (MCT/LCT) propofol is widely used as an intravenous anesthetic, especially in the intensive care unit. The present study aimed to assess whether MCT/LCT propofol is safe in the hyperlipidemic population for long-term use. Free fatty acids (FFAs) were used to establish high-fat stimulation of HepG2 and Huh7 cells. Subsequently, these cells were treated with propofol at the concentration of 0, 4, or 8 µg/ml for 24 and 48 h. The results indicated that the cell viability was notably decreased when the cells were stimulated with 2 mmol/L FFAs and treated with 12 µg/ml MCT/LCT propofol. Accordingly, we chose 2 mmol/L FFAs along with 4 and 8 µg/ml MCT/LCT propofol for the subsequent experiments. Four and 8 µg/ml MCT/LCT propofol inhibited FFA-induced lipid accumulation in the cells and significantly reversed acetyl coenzyme A carboxylase (ACC) activity. In addition, MCT/LCT propofol not only significantly promoted the phosphorylation of AMPK and ACC, but also reversed the FFA-induced decreased phosphorylation of AMPK and ACC. In conclusion, MCT/LCT propofol reverses the negative effects caused by FFAs in HepG2 and Huh7 cells, indicating that MCT/LCT propofol might positively regulate lipid metabolism.

Objective The aim is to investigate the association between coronary heart disease (CHD) and c.553G>T polymorphism of apolipoprotein A5 (ApoA5) gene and the influence of serum lipid level in the Hah ethnic population of Xinjiang. Methods The polymorphism of ApoA5 gene in 486 patients with CHD and 501 controls was analyzed by methods of polymerase chain reaction and restriction fragment length polymorphism analysis. Level of serum lipid in each patient was detected at the same time. Results There was significant difference in the distribution of genotypes between CHD group and controls group ( x2 = 8.757, P= 0.013 ). Non-conditioned logistic regression analyses, after adjusted for age, gender, smoking, total serum cholesterol, presence of hypertension and diabetes, revealed that individuals who carried T allele (TT + GT genotype) had an increased risk of CHD, compared to GG genotype (OR= 1.753,95%CI: 1.030-2.983, P<0.05 ). There was also a remarkable difference noticed in the level of serum triglyceride by genotypes in CHD group and control group (t=5.242, P<0.01; t=-3.499, P=0.001 ). Individuals in the two groups who carried T allele had higher level of serum triglyceride than those carried GG genotype. Individuals in CHD group who carried T allele had higher level of serum total cholesterol than those carried GG genotype (t=-2.465, P=0.014). Conclusion It seemed that the c.553G>T polymorphism of ApoA5 gene had influenced on the level of serum triglyceride and the total cholesterol among Han population in Xinjiang. c.553G>T polymorphism was associated with the development of CHD, while T allele might be an influencing risk factor on CHD.

This study was aimed to investigate the effects of xenogeneic antigen neu-Fc in combination with the recombinant human granulocyte-macrophage colony stimulating factor (GM-CSF) and Bacillus Calmette-Guerin (BCG) on the regulation of Th1 and Th2 immune response in vitro. The rat neu L2-S2 domain was engineered as a chimeric protein with human IgG Fc. The eukaryotic expression vector was constructed. The recombinant protein was stably expressed in CHO cells and purified by rProtein A Sepharose Fast Flow column. The recombinant protein was identified by SDS-PAGE and Western blot. Peripheral blood mononuclear cells (PBMNCs) were obtained by means of standard Ficoll separation from the blood of healthy donors. Neu-Fc-induced PBMNC proliferation was tested by MTT. The production of IL-12 and IL-10 was measured by ELISA. The results showed that the level of IL-12 decreased and IL-10 increased after PBMNCs were incubated with MCF-7 cultural supernatant. 10 nmol/L neu-Fc strongly induced the cell proliferation. Compared with neu-Fc or GM-CSF or BCG treatment alone, neu-Fc in combination with GM-CSF and BCG significantly stimulated IL-12 production and inhibited IL-10 production (p < 0.01). It is concluded that the neu-Fc can stimulate the proliferation activity of PBMNCs. neu-Fc, GM-CSF and BCG costimulation efficiently induces Th1 immune response.

Drug addiction is considered as a chronic, recurrent brain disease characterized by relapse. Repeated exposure to certain drugs, such as morphine, can produce deleterious sequelae, such as drug dependence, tolerance and compulsive drug seeking. In the present study, we investigated the dependence and psychological craving for morphine in rats using the conditioned place preference (CPP) paradigm. On the other hand, to study the effect of morphine on hippocampal sensory gating (N40), double click auditory-evoked potential was recorded during the chronic morphine administration, withdrawal and re-exposure to morphine in rats. The rats in morphine group received a course of morphine (10 mg/kg, i.p.) injection for 12 d, followed by 12 d of withdrawal, 1 d of re-exposure to morphine (2.5 mg/kg, i.p.) and 2 d of the second withdrawal. The rats in the control group were treated in the same way except that saline was applied instead of morphine. CPP test demonstrated that the method of drug administration in the present study induced dependence and psychological craving for morphine in rats. The results in the double click auditory-evoked potential experiment showed that during the chronic morphine administration, hippocampal N40 gating was damaged. In the initial 2 d of the first withdrawal hippocampal N40 gating in morphine group was reduced compared with that in the control group and it was significantly greater on the 3rd day, and then recovered gradually to the normal level from day 4 to day 12. After re-exposure to morphine, hippocampal N40 gating in morphine group was significantly reduced compared with that in the control group, and it remained at a lower level during the following 2 d, suggesting that hippocampal N40 gating in rats was more sensitive to morphine during re-exposure. Our results suggest that long-term repeated morphine administration and re-exposure to morphine disrupt hippocampal N40 gating, and that the effect of morphine addiction on the brain is possibly long-term.

OBJECTIVETo investigate the use of a 32P application device (AD) in the treatment of condyloma acuminatum (CA) in the rectum, and to compare its clinical effect with that of the microwave therapy.
METHODSThis study included 107 cases of CA in the rectum, 99 males and 8 females, aged 21-58 (33.6 +/- 9.4) years. Forty-six of the patients (the AD group) were treated with a self-made 32P application device, which, as a tube-shaped carrier of radionuclide 32P colloid, was fixed in the rectum at the diseased part for medication at 4.9-8.2 Gy for 3-5 hours once and 1-2 times a week. The other 61 (the microwave group) were treated by microwave burning under local anesthesia. Both groups of patients were followed up for over 3 months for comparison of the therapeutic results and observation of the stability and reliability of the 32P application device.
RESULTSThe rates of cure, reoccurrence and adverse reaction were 84, 8%, 13.0% and 8.7% in the AD group, compared with 40.3%, 55.7% and 75.4% in the microwave group, with statistically significant differences between the two groups (P < 0.01).
CONCLUSIONThe 32P application device, with its advantages of low cost, easy operation, good effect, high safety and reliability, low recurrence, fewer adverse events and good acceptability, is highly valuable for the treatment of CA in the rectum.

OBJECTIVETo investigate the diagnosis and treatment of macrocystic serous adenoma of the pancreas (MSAP).
METHODSThe clinical data of 5 patients with MSAP treated from October 1999 to October 2009 were retrospectively analyzed. There were 5 female and 1 male.
RESULTSOf the 5 patients, 3 patients presented with abdominal pain and fullness, 1 patient with jaundice, 1 patient with asymptomatic. Ultrasonography and CT could manifest macrocystic lesion of the pancreas; all the lesion showed a well-defined border, internal septations, enhanced cyst walls, with no intramural (mural) nodule and papillary projections; the wall was smooth and thin in 4 cases; irregular lobulation could be observed in 3 cases, round or oval in 2 cases; 2 cases had pancreatic duct dilatation, 1 case had biliary duct dilatation. The tumors located in the pancreatic body and tail in 3 cases, the tumors located the pancreatic head in 2 cases. The sizes of the tumors ranged from 6.5 cm to 13.0 cm (mean, 8.8 cm). Five patients all accepted surgical intervention. The main postoperative complication was pancreatic fistula (2 cases); all the fistula was cured. Recurrence or metastasis were not found in 5 patient followed up postoperatively from 8 to 35 months.
CONCLUSIONSMSAP has no specific symptoms. The imaging appearance of MSAP is similar to mucinous cystic neoplasm of the pancreas. The tumor can gradually grow up and produce compression symptoms. MSAP can be cured by complete resection.
