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.

Protein synthesis and nitrogen equilibrium have been investigated in the early postoperative period in 21 patients with carcinoma of esophagus and cardia after resection. They received 17-L-crystalline amino acid (AAM) and glucose infusion through parenteral route and were compared with a series' of 11 patients taking similar volume and calorie with protein hydrolysate (PRH) and glucose.In AAM series, the plasma protein could be maintained in preoperatiye level but not in PRH series. In AAM series a nitrogen equilibrium was reached while in PRH series was a negative equilibrium. The cellular immunity and serum amino acid spectrum were improved or replaced in both series, but they were better in AAM series. The improvement in nitrogen balance was probably mainly due to an increase in protein synthesis.

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.
