Methods 9 6 health examination people were selected who with glucose tolerance impairment diagnosis standard population in Jan to Feb 2015 in LaiZhou,There were no significant differences in age and sex composition between the two groups in 48 cases of experimental group and 48 cases in control group.There were no other diseases,and no drugs were taken to con-trol blood glucose.IGT patients in the experimental group using uric indican monitoring to establish personal diet guide, while the control group used normal health education guidance,the two groups respectively before experiment and at the end of detecting urinary indican,fasting blood glucose,2h glucose tolerance levels,and were compared.Results According to the findings of the two groups follow up and the experimental data collected during one year,at the end of the experiment the IGT patients in the experimental group levels of urinary indicant was (50.7±6.2 mg/L vs 78.5±7.9 mg/L),fasting blood glucose was (6.34±0.11 mmol/L vs 6.91±0.29 mmol/L),2h glucose tolerance was (7.81 ± 0.52 mmol/L vs 9.57 ± 1.13 mmol/L)which was lower than the control group.There was significant difference between two groups (t=2.0,2.6, 3.06,P<0.05).Compared with IGT in the experimental group at the end of the experiment,the level of uric indican was (50.7±6.2 mg/L vs 78.3±8.1 mg/L),fasting glucose was (6.34±0.11 mmol/L vs 6.78±0.19 mmol/L),2h glucose tol-erance was (7.81±0.52 mmol/L vs 9.33±0.93 mmol/L)was lower than before the start of the level (t=2.01,2.28, 2.83,P<0.05),and the difference was statistically significant.In terms of the outcome of the various stages of diabetes, IGT patients in the experimental group was significantly better than the control group (χ2=10.85,P<0.05),the difference was statistically significant.Conclusion Through the determination of uric indican to guide the glucose tolerance decrease in patients with a reasonable diet,is conducive to glucose tolerance in the patients with impaired on blood glucose control,can effectively reduce the glucose tolerance decrease (IGT)conversion to diabetes mellitus (DM),change to a positive direction.

Objective To study the differences in levels of plasma cytokine profiles including interleukin-6 (IL-6),interleukin-10 (IL-10),tumor necrosis factor-alpha (TNF-alpha) and C-reactive protein (CRP) between healthy controls and people with smoking and alcohol drinking behaviors at different ages,and to investigate the correlation of plasma cytokine profiles with age,smoking and alcohol drinking behaviors.Methods The concentrations of IL-6,IL-10,TNF-alpha and CRP in 350 healthy volunteers,60 cigarette smokers and 65 people with smoking and alcohol drinking behaviors were detected by ELISA.All subjects were grouped by age,gender,smoking and alcohol drinking behavior.The differences in the levels of plasma cytokine profiles among groups were analyzed by statistics software SPSS18.0.Results The concentrations of IL-6 and CRP in 25-39years,40-49 years,50-59 years and over 60 years groups were (1.1±0.7) ng/L,(1.5±0.1) ng/L,(1.7±0.2) ng/L,(2.1±0.1) ng/L and (3.1±1.0) mg/L,(4.4±±0.6) mg/L,(6.2±1.7) mg/L,(8.0±0.8) mg/L,respectively.The concentrations of IL-6 and CRP were significantly increased with age (F=1.60,7.50,P=0.012,0.043),while the concentrations of IL-10 and TNF-alpha were not correlated with age (F=4.20,4.80,P=0.178,0.421).There were no significant differences in the concentrations of IL-6,IL-10,TNF alpha and CRP between males and females (P＞0.05).The plasma CRP level was higher in smoking group than in control group [(6.8±0.6) mg/L vs.(3.1± 0.4) mg/L] and was highest in smoking-alcohol group [(9.5±0.5) mg/L vs.(6.8±0.6) mg/L,(3.1±0.4) mg/L,F=8.40,P=0.046].Compared with the control group,IL-6 level was increased and IL-10 level was decreased in smoking group and smoking-alcohol group.There were no significant differences in levels of IL-6,IL-10 and TNF-a among the three groups (F=2.90,4.30,4.80,P=0.089,0.672,1.231).Conclusions The plasma levels of IL-6 and CRP are significantly increased with age,but the plasma levels of IL-10 and TNF-a have no correlations with age.The plasma levels of IL-6,IL-10,TNF-a and CRP are not affected by gender.CRP level is significantly influenced by smoking and alcohol drinking behaviors,which should be taken into consideration to establish the reference values.

Objective To analyze the epidemiological characteristics of other-infectious diarrhea (OID) in Shaanxi Province from 2006 to 2015 to further clarify the prevention and control strategies.Methods We collected data from the Infectious Disease Report Information System in China for Disease Prevention and Control and made a statistical description of the epidemiological characteristics of incidence distribution in Shaanxi from 2006 to 2015.Results Totally 207 437 cases of other-infectious diarrhea were reported in Shaanxi Province during 2006 -2015,with the average yearly incidence rate of 52.43/105.The incidence number was higher in males (126 673 cases) than in females (80 764 cases),with male-female ratio of 1.57 ∶ 1.The diseases were most serious in age groups 0-and 1-4 years,accounting for 72.48％.The top-three careers of reported cases were scattered children (74.88 ％),farmers (10.75 ％) and students (5.75 ％),respectively.The cities with the highest incidence in Shaanxi Province were Baoji,Yan'an and Ankang.Two high-incidence seasons were summer (July to August) and winter (November to December).The main pathogen of viral diarrhea was rotavirus,but laboratory-confirmed proportion was low (4.60％).Conclusion Other-infectious diarrhea,especially infection caused by rotavirus in autumn and winter,mainly occurred in children younger than 5 years old.Etiological diagnosis should be strengthened because of the poor laboratory diagnosis reporting rate.

Objective To construct and identify the recombinant retroviral vector containing five copies of hypoxia responsive elements (5HRE)and neurotrophin-3 (NT-3 ).Methods Using PCR,enzyme digestion and DNA ligase,5HRE and human derived NT-3 were cloned into the retroviral vector plasmid (pLNCX)to construct the recombinant retroviral vector plasmid pLNCX-5HRE-SV40-NT3-IRES-EGFP.The retrovirus RV-5HRE-NT3 was packaged in the PT67 cells,and then it was purified and concentrated by high-speed centrifugation.After infected for 48 h with the concentrated retrovirus,the number of the EGFP positive cells in the NIH 3T3 cells was counted by fluorescence activated cells and sorted to calculate the retrovirus titer.Results The retroviral vector plasmid,pLNCX-5HRE-SV40-NT3-IRES-EGFP,was successfully constructed,and the retrovirus was packaged and defined as RV-5HRE-NT3.After purification and concentration,the retrovirus titer reached 9.1 × 10 6 cfu/mL. Conclusion The recombinant retroviral vector which carried out hypoxia-regulated expression of NT-3 was successfully constructed.It may provide basis for studies on hypoxia-regulated expression of the exogenous genes.

Objective To observe the clinical curative effect of Depmas double blood purification system for acute severe organophosphorus pesticide poisoning.Methods Retrospectively study was carried out on 147 patients of acute severe organophosphorus pesticide poisoning.Patients were divided into four groups,the conventional treatment group treated with drug therapy,hemoperfusion group given HA230 hemoperfusion in addition to conventional treatment,plasma exchange combined with hemoperfusion group given HA230 hemoperfusion and plasma exchange therapy in addition to conventional treatment,and Depmas group treated with plasma separation by Baxter blood fiber and then given series HA230 and BS330 hemoperfusion treatment on the separated plasma in addition to conventional treatment.Survival rate,mean survival time of death patients,the concentration changes of cholinesterase and bilirubin in peripheral blood were observed.Results Compared to the conventional treatment group,survival rates of hemoperfusion group,hemoperfusion combined with plasma exchange group and Depmas group were higher,the mean survival time was longer,the cholinesterase concentration in peripheral blood was higher and the elevated bilirubin concentration was decreased with the differences statistically significant (P＜0.01).Compared to hemoperfusion group,the survival rates of hemoperfusion combined with plasma exchange group and Depmas group were higher,the mean survival time was longer,the cholinesterase concentration in peripheral blood were higher and the elevated bilirubin concentration was decreased with the differences statistically significant (P＜0.05).Besides,there were no significant differences between the survival rate,mean survival time,peripheral blood cholinesterase and bilirubin concentration of hemoperfusion combined with plasma exchange group and that of Depmas group (P＞0.05).Conclusions Depmas dual blood purification system has remarkable curative effect for the treatment of acute severe organophosphorus poisoning.

Objective To explore the characteristics of intestinal Microbiota in T2DM patients by two molecular fingerprint technologies,and investigate the correlation of intestinal microbiota and T2DM,and evaluate the application value of two fin-gerprint technologies.Methods Fecal samples of 8 healthy groups and 7 diabetes patients were collected.Then the total DNA of gut microbiota was extracted.Through the analysis of products by two molecular fingerprints of ERIC-PCR and DGGE-PCR,ecological characteristics of diversity and similarity of gut microbiota were obtained in healthy groups and dia-betes patients.Results Compared to healthy groups,the number of bands and Shannon-Wiener index of gut microbiota in di-abetes patients was decreased but no statistical significance.The similarity in patients group was declining(P <0.05),and the construction of gut microbiota was inclined to differ.Two fingerprint technologies of ERIC and DGGE could directly re-flect the diversity of gut microbiota and were the modern molecular biological techniques without depending on cultivation. ERIC was simple and convenient,had a better reflection of microbial diversity,but gel band cutting and regarded asa proper approach with higher diffraction efficiency and excellent repetition to studysequencing couldn’t be performed since there were more influencing factors on the experiment.DGGE could better reflect the ecological characteristics such as microbial diversity and similarity,and selecting bands,gel band cutting and sequencing could be done.Conclusion The composition and construction of gut microbiota in diabetes patients were changed,which suggests the occurrence of the disease had the correlation with gut microbiota.ERIC and DGGE is regarded as a proper approach with higher diffraction efficiency and ex-cellent repetition to study intestinal microbiota,but also gel band cutting,sequencing,bacteria identification can be performed by DGGE,both can be used in combination.

Objective To evaluate the change of serum creatinine (Scr) before and after administration of contrast agent in different dose,to observe the difference of dog's kidney tissue with electron microscopy and investigate the effect of contrast agent on renal function.Methods Twelve dogs were divided into four groups randomly:the control group,the low dose group,the moderate dose group and high dose group.After the administration of different doses of iodine contrast agent at the same rate,the changes of Scr and microscopic structure were compared before administration and 48 hours later.Results The differences of Scr before and 48 hours after administration were (4.6±1.6) μmol/L,(6.7±2.5) μmol/L,(6.9±4.5) μmol/L,(5.1± 1.9) μmol/L for control group,low dose group,moderate dose group and high dose group,respectively.There was no statistically significant difference among the groups (P ＞0.05).In high dose group,the mitochondria of tubular epithelial cells were swelling and obvious vacuoles were observed.Only a small amount of vacuoles existed in the renal tubular epithelial cells in low dose group.Conclusion Compared with the moderate and high dose group,the low-dose iodine contrast agent have less damage to the kidney cells of the dogs.

OBJECTIVETo investigate whether intracerebral hemorrhage (ICH) can promote neurogenesis in the dentate gyrus (DG) of rat hippocampus.

METHODSWestern blot analysis, immunohistochemical staining, and immunofluorescent double labeling combined with confocal microscope were used to detect neurogenesis in the DG of the hippocampus in rats after ICH.

RESULTSThe expression of DCX protein in the ipsilateral DG of the hippocampus was enhanced in the rats 1 day after ICH (0.202∓0.062) as compared with that in normal rats (0.127∓0.088), reaching the peak level at 14 days (0.771∓0.108, P<0.01) and beginning to decrease at 28 days (0.582∓0.121, P<0.01). Meanwhile, DCX-positive cells and BrdU-positive cells, and DCX/BrdU double-labeled cells were detected in the DG of the hippocampus. Compared with those in the control group, BrdU/NeuN double-labeled cells were markedly increased in the granular cell layer of the DG at 28 days after ICH (1.808∓1.020 vs 5.654∓1.671, P<0.01).

CONCLUSIONICH can promote neurogenesis in the DG of rat hippocampus.

Through studying the process of glycerol fermentation to 1, 3-propanediol(1, 3-PD) by Klebsiella pneumoniae, it was found that the cell growth and product (or by-product) production were under salt stress. Cell growth and product formation kept high rate at low salt concentration. High salt concentration led to low growth of cells, final concentration of 1, 3-PD and conversion from glycerol to 1, 3-PD, and, 1, 3-propanediol oxidoreductase activity decreased. When the salt concentration in 5 m3 bioreactor was controlled under appropriate manner, the concentration of 1, 3-PD production was markedly enhanced. The final 1, 3-PD concentration ,the conversion of glycerol to 1, 3-PD and productivity were 64 g/L, 61% and 2.1 g/(L x h).
