Objective To assessed the distribution of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in Xinjiang Uygur and Han nationality populations,and to investigate correlation and the incidence of all cases of macrovascular disease (coronary artery disease,carotid atherosclerosis and peripheral arterial disease)and analysis of risk factors.To further study the correlation between the incidence of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in type 2 diabetes melli-tus(T2DM)of Han and Uygur ethnic and the incidence of all cases vascular disease,then to analysis the risk factors. Methods 497 adults with T2DM who were treated in the Endocrinology department in hospital from May 2012 to April 2014 were involved in this study,including 298 Uygur patients and 199 Han patients.215 non -T2DMpatients who were treated in the Cardiology department in hospital were also involved in the study,including 93 Uighur patients and 122 Han patients.Then the total 712 patients were detectedby using PCR -SNP Stream technology to analyse rs2383206.rs10757278 loci SNP genotyping.The relevant results were compared with t test,two different genotype distribution and allele frequency were compared with χ2 test,multiple factors analysis were calculated by Logisitic regression.Results The distribution of genotype with two SNP loci had no significant difference between the patients in Uygur group and Han group (rs2383206χ2 =5.570,P =0.062;rs10757278 χ2 =2.721,P =0.257 ),and there's no significant difference between the patients with macrovascular disease and non -macrovascular disease in all patients(rs2383206χ2 =0.120,P =0.950;rs10757278 χ2 =1.027,P =0.598).Logisitic regression analysis showed that the incidence of macrovascular was significantly associated with increasing age(χ2 =28.820,P =0.000)and fatty liver(χ2 =5.210,P =0.020)in Uighur group with type 2 DM.In Han group with type 2 DM,the macrovascular was significantly associated with the increase of age (χ2 =19.980,P =0.000),elevated fasting blood glucose (FPG)(χ2 =4.070,P =0.044)and poor controlled with glycosylated hemoglobin (χ2 =4.280,P =0.040). Conclusion This study found that there's no correlation between two single nucleotide polymorphisms (SNPS)loci (rs2383206.rs10757278)on chromosome 9 p21 large with macrovascular in Uygur group and Han group.Increasing age,higher FPG and poor controlled with glycosylated hemoglobin combined with fatty liver were the risk factors for macrovascular.

Objective:To explore the effects of dexmedetomidine on the blood glucose,tumor necrosis factor-α (TNF-α) and interleukin-6(IL-6) in perioperative patients with neurosurgery.Methods:50 patients with meningioma who were ready to accept craniotomy in department of neurosurgery of our hospital from February 2016 to November 2016 were enrolled,they were randomly divided into research group and control group,with 25 patients in each group.The research group was given DEX 1.0 μg/kg at 10 min before anesthesia,which was added in 0.9％ sodium chloride injection 50 mL,the injection was finished in 10 min,then the DEX change to the rate of 0.5 μg/kg/h.Control group was given 0.9％ sodium chloride injection with constant rate and volume.Record heart rate (HR),mean arterial pressure (MAP) and blood glucose,serum TNF-α,IL-6 levels of the two groups at 10min before anesthesia(T1),after the anesthesia (T2),the beginning of surgery(T3),1 hour after the surgery beginning(T4),the end of surgery(T5).Results:Compared with T1,HR of the two groups at T2 and T3 raised significantly,but research group was lower than control group(P＜0.05);In research group,compared with T1,MAP at T3 raised significantly;in control group,compared with T1,MAP at T3 and T4 raised significantly,but MAP of research group at T3 and T4 were lower than control group (P＜0.05).Compared with T1,blood glucose of the two groups at T2,T3,T4 and T5 raised sig-nificantly,but the research group at same points were lower than control group (P＜0.05).Serum TNF-α,IL-6 levels of control group at T2,T3 and T4 were significantly higher than T1 (P＜0.05),which in research group at different time points had no significant change (P＞0.05),and were lower than control group at T2,T3 and T4 (P＜0.05).Conclusion:DEX could maintain stable hemodynamics,antiinflammation,inhibit elevated blood glucose,so as to reduce the inflammatory response and stress response in patients with neurosurgery,then it could promote these patients postoperative recovery.

Aim To research the effects of total flavones of rhododendra(TFR)on transient receptor potential vanilloid receptor 4(TRPV4)in cerebral basilar arteries(CBA)of rats subjected to ischemia/reperfusion(IR)injury.Methods The model of total brain IR was established by four-artery occlusion(4-VO)method in rats.Arterial pressure perfusion and cell membrane potential recording methods were used for surveying the dilatation and hyperpolarization of TFR and ruthenium red(RR,an inhibitor of TRPV4)in the KCl-preconstricted CBA ex vivo in rats subjected to IR.Quantitative real-time polymerase chain reaction(qRT-PCR)and Western blot were utilized to investigate the TRPV4 mRNA and protein expressions of TFR and RR in cerebrovascular endothelial cells of CBA in vivo in rats subjected to IR.Results 11～2 700 mg·L-1 TFR significantly induced concentration-dependent hyperpolarization and dilatation in the KCl-preconstricted CBA in rats subjected to IR.TFR still produced degenerative hyperpolarization and dilatation by removal of endothelium in CBA,which was remarkably attenuated as compared with endothelium-intact group(P<0.01).After removal of NO and PGI2 vasodilatation,TFR obviously elicited the hyperpolarization and dilatation that were further decreased by RR(an inhibitor of TRPV4)in IR CBAs.TFR pretreatment apparently increased the level of TRPV4 mRNA and protein expressions in IR CBAs.These effects were restrained by RR,an inhibitor of TRPV4.Conclusions TFR could mediate endothelium-dependent and endothelium-independent effects.The endothelium-derived dilatation may be related to the increase of endothelium activity and endothelium-derived hyperpolarizing factor(EDHF)generation and release that have been promoted by TFR,and secondarily activating TRPV4,which results in Ca2+ inflow and subsequent hyperpolarization of vascular smooth muscle cell membrane and vasorelaxation.

OBJECTIVE To investigate the distribution and the resistance rate of Shigella in Anhui Province to guide the choice of antibacterials. METHODS Ninety one strains of Shigella were cultured in Sep 2005.The groups were identified by biochemical and serologic tests.Susceptibility of 91 strains of Shigella in Anhui to various antibiotics was tested using standardized custom dilution MIC panels according to CLSI(2005) guidelines. RESULTS There were 57 strains of Shigella flexneri,31 strains of S.sonnei and 2 strains ofS.boydii among 91 strains of Shigella.The resistance rates of Shigella to cefoperazone/sulbactam and piperacillin/tazobactam were remarkably lower than to other third generation cephalosporins.The susceptible rates to carbopenems were 100%.The resistance rates to ciprofloxacin lactate and pazufloxacin mesilate were 27.47% and 32.97%,respectively. CONCLUSIONS There is a certain resistance rate of the Shigella to fluoroquinolones and the third generation cephalosporins.More attention should be paid to the surveillance and control of such resistance.

Aim To study the immunomodulatory activity of total flavonoids of Litsea Coreana Leveille (LCTF) on cyclophosphamide(CY)-induced immunosuppressive mice. Methods CY (50 mg?kg-1) was administered by intraperitoneal(ip)injection for 2 consecutive days to induce immunosuppressive model. Carbon clearance, quantitative hemolysis and DNFB-induced delayed-type hypersensitivity(DTH) were applied to assay effects of LCTF on nonspecific immunity, humoral immunity and cellular immunity. Results In carbon clearance test, the clearance index (K) and values of phagocytic index (?) were elevated by LCTF (200 and 400 mg?kg-1), indicating the phagocytosis of macrophages was enhanced in immunosuppressive mice.In quantitative hemolysis, productions of IgM and IgG in serum and hemolysin in splenocytes were enhanced in immunosuppressive mice by LCTF (100 and 200 mg?kg-1). LCTF (200 and 400 mg?kg-1) obviously increased DTH reactivity in immunosuppressive mice. LCTF not only increased percentages of T cells expressing CD4+ and CD8+,but also enhanced the ratio of the two subset of T lymphocyte,and LCTF (200 and 400 mg?kg-1) could also improve IL-2 production of spleen lymphocytes. Conclusion LCTF showed significant immunomodulatory property on immunosuppressive mice through specific and nonspecific immunity.

Objective To investigate the effects of liver X receptor agonist on the expressions of C-reactive protein and CD40 ligand and smooth muscle cell ?-actin in the aorta of ApoE gene knockout mice with earlier atherosclerosis. Methods Male ApoE gene knockout mice (8-week old) were divided randomly into control group and T0901317 treatment group (n=6 in each group). The mice in T0901317 group were administered intraperitoneally with T0901317 at the dose of 20 mg?kg-1?d-1 for 4 weeks. Mice in the control group were only given equivalent amount of dimethyl sulfoxide (DMSO). The expressions of C-reactive protein and CD40 ligand and smooth muscle cell ?-actin were detected by immunological histochemical method. Results The expressions of C-reactive protein and CD40 ligand in the atherosclerotic plaque in the aortic wall were significantly lower in T0901317 group as compared with those in the DMSO control group (P0.05). Conclusion Liver X receptor agonist may reduce the formation of atherosclerotic lesions by inhibiting the inflammation and the expressions of C-reactive protein and CD40 ligand in the aorta of ApoE gene knockout mice.

Aim To study the transport of geniposide and geniposide in Zhizi Bopi Decoction in MDCK cell membrane model. Methods The safety concentration of geniposide and Zhizi Bopi Decoction in MDCK cells were determined by MTT assay. Then the MDCK cell membrane model was used to investigate the transport of drugs. Firstly, the effects of time, drug concentra-tion, P-gp inhibitor and EDTA on the absorption and transport of geniposide were studied systematically. Secondly, the differences were compared between the transport of the same concentration of geniposide as single compound and that in Zhizi Bopi Decoction in MDCK cell model. The drug concentration was deter-mined by high performance liquid chromatography ( HPLC) to calculate the apparent permeability coeffi-cient (Papp). Results Geniposide transport in MDCK cell monolayer was time and concentration dependent. P-gp inhibitors had no significant effect on its transport and the transport of geniposide was enhanced by ED-TA. The absorption Papp of different concentrations of geniposide in Zhizi Bopi Decoction were ( 8. 96 ± 0. 35 ) × 10 -7 cm · s-1 , ( 8. 95 ± 0. 38 ) × 10 -7 cm · s-1 and (9. 16 ± 0. 30) × 10 -7 cm·s-1, significantly higher than the absorption Papp of geniposide as single compound(5. 85 ± 0. 44) × 10 -7 cm·s-1, (6. 88 ± 0. 38) × 10 -7 cm·s-1 and (6. 31 ± 0. 19) × 10 -7 cm ·s-1 ( P<0. 05 ) . Conclusion The transport of ge-niposide in MDCK cell membrane model is passive transport and is not affected by P-gp. Geniposide may transport via the paracellular route. The Zhizi Bopi De-coction can increase the absorption of geniposide.
