Tianjin Medical Journal 2015;(12):1433-1436
Objective To investigate the associations of alcohol consumption with the outcome of three-year pre-dia?betes. Methods The objects of this study were selected from the epidemiological study of cancer risk of Chinese patients with type 2 diabetes mellitus (T2DM) in Luzhou area. A total of 1 125 cases with pre-diabetes were selected from the base?line survey. Patients divided into four groups including non-alcohol drinking group, small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. Patients also were divided into two groups according to body mass index (BMI, more than 24 kg/m2). The patients were followed up for three years. The incidence rates of diabetes mellitus were compared between different drinking groups and different BMI groups. Results A total of 1 116 cases were completed the follow-up , 9 cases were lost to follow-up. The incidence rates of DM were 18.81%, 8.80%, 16.51%and 26.53%for non-al?cohol drinking group, small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. Cox proportional hazard regression analysis showed that the relative risk ratios and 95%CI of the gender, age, BMI, calorie, base?line blood glucose were 0.49 (0.31-0.79), 1.15 (0.69-1.92) and 1.95 (1.25-3.04) for small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. In the group of BMI<24 kg/m2,the relative risks and 95%CI were 0.40 (0.20-0.80),0.77 (0.30-1.97) and 1.10 (0.46-2.64) for small alcohol drinking group, moderate alcohol drinking group, and large alcohol drinking group. In the group of BMI≥24 kg/m2, the relative risks and 95%CI were 0.62 (0.33-1.66),1.49 (0.80-2.80) and 2.64 (1.55-4.47). Conclusion Small amount of alcohol drinking can reduce the incidence of DM in predia?betes people with BMI<24 kg/m2. Large amount of alcohol drinking is the risk factor of incidence of DM in people with BMI≥24 kg/m2.

Objective: Our aim was to investigate whether the immune RNA (iRNA) can inhibit the endotoxin-induced uveitis (EIU). Methods: The EIU was induced by injecting endotoxin of E.Coli into rats hypodermically. iRNA was abstracted from the livers and spleens of the rabbits which had been injected by E.Coli six times. The iRNA was introduced intraperitoneally into the rats both at half an hour and 3 hours after the injection of endotoxin. The effect of iRNA was evaluated by protein determination and cell count in aqueous houmer(AH). Results: The appearance of EIU in the iRNA treated rats was delayed, about 3 hours later than the rats received only endotoxin injection. The AH protein decreased by 58.34% and cellular infiltration decreased by 27.62% in iRNA treated group at the 24 hours. Conclusion: The iRNA may partly prevent the development of EIU and significantly reduce the severity of EIU.

AIM To study the effect of ATP sensitive potassium channel(K ATP ) opener pinacidil on the current induced by nicotine in cultured rat superior cervical ganglia. METHOD Whole cell patch clamp technique. RESULTS Pinacidil inhibited nicotine induced current when in higher dose(100 ?mol?L -1 ), but had no effect on the desensitization of nicotinic receptors. K ATP antagonist glibenclamide didn't influence the inhibitory effect of pinacidil on nicotinic current. CONCLUSION Pinacidil had an inhibitory effect on nicotine induced current in rat superior cervical ganglia and this effect wasn't mediated by K ATP .

Nicotinic and muscarinic acetylcholine receptors have the same endogenous ligand ACh and are distributed together in many tissues, so it is reasonable to believe that there must be some interactions existed between them. The functions of muscarinic receptors in the tissues innervated by the parasympathetic cholinergic postfibers, can be modulated by the ganglionic nicotinic receptors through stimulating ACh release. In ganglia, the postsynaptic nicotinic receptor activities can be modulated by the presynaptic muscarinic and nicotinic autoreceptors through regulating ACh release. Moreover, The functions of muscarinic receptors can be changed by nicotinic receptor desensitization or blockade. The two types of receptor act on each other and keep in a varied homeostasis of cholinergic nervous system.

Objective To investigate the correlation between the walking function status and the quality of bowel preparation for colonoscopy in the elderly patients. Methods Two hundreds elderly (over 70 years) patients undergoing colonoscopy were selected. The walking function status was evaluated by the ability of daily living scale (Schonberg index), and the patients were divided into normal walking group (114 cases) and difficulty walking group (86 cases). Patients in the 2 groups accepted the unified intestinal preparation programs and education guidance. The patients′ compliances to preparation instructions were observed. The causes of non-compliance were investigated. The quality of bowel preparation was assessed using the Boston bowel preparation scale (BBPS). The correlation between walking function status and compliance or quality of bowel preparation was analyzed with the Spearman rank correlation test. Results The proportion of failing to completely take the intestinal cleanser was lower in the difficulty walking group than that in the normal walking group: 53.5% (46/86) vs. 26.3%(30/114), and there was statistical difference (χ2=15.362, P<0.05). The reasons for failing to completely take the intestinal cleanser in the difficulty walking group were as follows: unconvenient of frequently walking to the restroom to defecate (39 cases) , forgetting (4 cases) and adverse reactions (3 cases). The good proportion of bowel preparation compliance and sufficient rate of bowel preparation in difficulty walking group were significantly lower than that in normal walking group: 41.9% (36/86) vs. 65.8%(75/114) and 55.8% (48/86) vs. 72.8% (83/114), and there were statistical differences (χ2 = 11.365 and 6.264, P<0.01 or<0.05). There was no significant difference between 2 groups in the constituent ratio of strictly implementing the bowel preparation program (P>0.05). The correlation analysis result showed that the walking function status was positively correlated with compliance and quality of bowel preparation in the elderly patients (r=0.238 and 0.177, P<0.05). Conclusions The walking function status is correlated to the quality of bowel preparation in elderly patients undergoing colonoscopy. Difficulty walking may indicate the poor compliance and poor colonoscopy preparation in the aged.

AIM: To study the inhibitory effect of IGF binding protein-4(IGFBP-4),especially in corporation with heparin on the pathopoiesis of insulin-like growth factor-1(IGF-1) in alveolitis and fibrosis.METHODS: The diploid human embryonic lung(HEL) fibroblasts were incubated respectively with control,100 ?g/L IGF-1,100 ?g/L IGF-1+100 ?g/L IGFBP-4,100 ?g/L IGF-1+200 ?g/L IGFBP-4,100 ?g/L IGF-1+100 ?g/L IGFBP-4+100 ?g/L heparin,100 ?g/L IGF-1 + 100 ?g/L IGFBP-4+200 ?g/L heparin,100 ?g/L IGF-1+100 ?g/L heparin,100 ?g/L IGF-1+200 ?g/L heparin for 24 h.Then the content of glucose transporter-4(GLUT-4),hexokinase-2(HK-2),collagen-4 and elastin were detected,respectively.RESULTS: Compared with control group,HK-2,GLUT-4,elastin and collagen-4 expressed in IGF-1 group were increased obviously.The expression in the group of IGFBP-4 plus IGF-1 was more than that in IGF-1 group.However,all expression was depressed strikingly when heparin was added.CONCLUSION:(1) IGF-1 apparently stimulates HK-2,GLUT-4,elastin and collagen-IV secretions from lung fibroblasts.(2) The intact IGFBP-4 associated with heparin can inhibit the pathopoiesis of IGF-1.
