Objective To explore the alterations of intestinal mechanical barrier during the nonalcoholic fatty liver disease (NAFLD) progression. Methods To establish NAFLD rats' model,ninety male SD rats were divided into three groups equally: normal-diet group, high-sucrose diet group and high-fat diet group. At the 4th, 8th and 12th week each time point, ten rats were sacrificed in each group. Another twenty SD rats were randomly divided into carbon tetrachloride (CCl4) group and control group. The liver injured model of CCl4 group was induced by CCl4 ; all the rats of these two groups were killed at the 4th week. The degree of liver steatosis was observed through HE staining of liver paraffin sections. The lipopolysaccharide (LPS) level of portal vein blood was measured by limulus test. The occludin expression in intestinal mucosal was detected by immunofluorescent assay,and the fluorescence intensity was scored. The morphology change of intestinal mucosa tight junction was observed through electron microscopy. Results The liver histopathology suggested that NAFLD and liver injured rats' model was successfully established. There was no statistical significance of LPS level between high-sucrose diet group and normal diet group at all the time point (P＞0.05). At the 4th and 12th week, there was no statistical significance of LPS level between high-fat diet group and normal diet group (P＞0.05), while it was significantly higher in high-fat diet group than normal diet group at the 8th week (P＜0. 05). There was no statistical significance of LPS level between CCl4 group and control group (P＞0. 05). At the 8th week, the expression of occludin in normal-diet group, high-sucrose diet group and high-fat diet group was 1.80±0. 42, 1. 50 ± 0. 53 and 1.30±0.67, respectively, the expression was a little bit lower in high-sucrose diet group and high-fat diet group than in normal diet group, the difference was statistical significance (P＜0. 05). At the 12th week, the expression of occludin was significantly lower in high-sucrose diet group and high-fat diet group than normal diet group. The expression of occludin was significantly lower in CCl4 group (0.60±0.16) than in control group (1.80±0. 42) (P＜0. 05). No obvious morphology changes of tight junction was found in high-sucrose diet group, high-fat diet group and CCl4 group at each time point.Conclusion The expression of occludin decreased gradually during the non-alcoholic fatty liver disease progression. So in the NAFLD treatment, besides improving insulin resistance and protecting liver function,the protection of intestinal mucosa barrier as early as possible may slow down the progression of liver injury.

The traditional Najiafa (day-prescription of acupoints) can be classified into two schools of YAN Ming-guang and XU Feng. The author studied the YAN Ming-guang and XU Feng Najia fa from the aspects of the academic source, selection of points, existing researches and current application. When compared between the two schools, it is held that Najia fa of YAN Ming-guang school more accords with the law of point selection according to Ziwu Liuzhu Zhenfa (acupuncture based on the midnight-noon and ebb-flow doctrine) in following the original doctrine, selection of points on the base of day-prescription, and time-meridian relation of Sanjiao (triple energizer) and Pericardium meridians. Therefore, it is concluded that the YAN's Najia fa should not be neglected and forgotten. Its inheritage and further study should be carried out so as to enrich the ways of study as well as the prevention and treating methods in clinic.

Two hundred male and 200 female patients with type 2 diabetes mellitus admitted from January 2007 to April 2008 were enrolled in the study. Of them, 267 were diagnosed as non-alcoholic fatty liver disease (NAFLD) by ultrasonography. The measurements included:body mass index (BMI) ,waist-to-hip ratio (WHR) ,fasting blood glucose( FBG), ALT, AST, total bilirubin(TBIL), cholesterol(CHO),triglyceride(TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol ( LDL-C) ,serum creatinine (Cr), supersensitive C-reactive protein (hsCRP) and urine albumin/creatinine. The relationship of above factors with NAFLD was determined. Our data showed that male NAFLD patients were in general younger than female. The BMI ( t = 11. 361, P = 0. 000), waist circumference ( t = 9. 771, P =0. 000), hip circumference (t = 10. 469, P =0. 000) ,TG(t =7. 352, P =0. 000) and hsCRP (t =2. 242,P =0. 026) of NAFLD patients were significantly higher than those without NAFLD. The hsCRP of patients with central obesity was also significantly higher than those without central obesity (t = 0. 266, P = 0. 045 ).BMI and TG were positively correlated with NAFLD. Waist circumference was an independent factor of NAFLD in male patients, same as hip circumference with NAFLD in female patients. In conclusion, gender,central obesity and dyslipidemia may be risk factors for NAFLD in patients with type 2 diabetes mellitus.

Frailty is an age-related non-specificity status caused by a decline of physiological reservation,which leads to an increase of vulnerability in body and decrease of ability in stress resistance.The pathophysiology of frailty involves multiple systems including neuromuscular system,metabolism and immune system.Studies have showed that frailty is closely related with negative events of elder people.People with frailty are subject to higher risks for fall,hospitalization,and mortality.However,the development of frailty can be delayed if early prevention or interventions are performed.Prospective cohort studies have showed that the risk factors for frailty include age,gender,family history of obesity,BMI,waist circumference,blood pressure,hyperglycemia,smoking and lack of exercise.Among them,nutrition,exercise and therapeutic drugs are hot spots in prevention study.Here,we reviewed the intervention studies by focusing on nutrition,exercise and therapeutic drugs in frail population.
