Objective:To observe the therapeutic effects of plasma exchange in severe hepatitis. Methods:53 cases served as treatment group and 49 cases as control group. Both groups were similar in basic medical treatment, and an additional treatment of plasma exchange was carried in the treatment group. 186 times of plasmas exchange were performed in the treatment group, to observe and compare the changes in patients of the 2 groups in symptoms、liver functions and survival rates. Results:The clinical symptoms of patients in the treatment group were obviously improved, the liver functions were also obviously improved in the treatment group as compared with the control group, and the survival rate of treatment group was higher than that of control group(73.58% vs 46.94%, P

Nowadays,small peptides are always expressed in the form of fusion protein.The expression product contains many superfluous amino acids which can affect the biological functions of small peptides even expressed by GST fusion protein expression system.SUMO protease can cut SUMO fusion protein expressed by fusion expression system without any amino acid residues left on target protein thus become a hot topic in this field.Recombinant His-UlP1/pET3c/BL21(DE3)engineering strain was constructed by genetic engineering technology and the expression conditions were optimized in shake flaks.The process of high density fermentation was explored and different purification conditions were detected by chromatography.The results showed that SUMO protease could be expressed well after inducing the engineering strain by IPTG of 1.0mmol/L at 30℃ for 6 hours.The expression level of the strain in fermentation pots could reach 24.3% analyzed by SDS-PAGE.The purity of SUMO protease was more than 98% after further purification by cation exchange chromatography.The yield was 355mg SUMO protease per liter fermentation liquid.Western blot analysis demonstrated that there were immune reactions between IlP1 and 6?His antibodies,so it has established a good foundation for large-scale industralazation in the future.

Objective To investigate the relationship between serum transforming growth factor- β1(TGF- β1) levels and early diabetic nephropathy and clarify whether valsartan plays a role in renal protection by reducing the level of serum TGF-β1. Methods The study subjects were divided into four groups:control group (30 cases); normal albuminuria group 1 (NA1 group with 12 cases, U MA/Cr < 10 μg/mg combined with type 2 diabetes);normal albuminuria group 2 (NA2 group with 19 cases,UMA/Cr 10-30 μg/mg combined with type 2 diabetes); microalbuminuria group ( MA group with 35 cases, U MA/Cr 31-300 μg/mg combined with type 2 diabetes). All these type 2 diabetic patients were suffering from diabetic retinopathy, and valsartan ( 80 mg/d) were medicated for those combined with hypertension. The serum TGF-β1 levels were measured by enzyme-linked immunosorbent assay in all subjects. Results Serum TGF- β1 levels in three diabetes groups were (7.41 ± 2.68 ), ( 10.52 ± 4.10), (22.98 ± 43.74) ng/L, respectively, all of which were higher than those in control group [(4.25 ± 5.82) ng/L] (P < 0.05). There were significant differences in serum TGF- β1 levels among MA group, NA2 group and NA1 group (P < 0.05 ). Serum TGF-β1 levels in NA1 group with valsartan treatment significantly decreased compared with those without valsartan treatment (P < 0.05), whereas there was no significant reduction in NA2 and MA group with valsartan treatment (P > 0.05). Conclusions High serum TGF-β1 level may be associated with type 2 diabetes and early diabetic nephropathy. Early intervention of valsartan may be delay the onset and development of diabetic nephropathy by decreasing the serum TGF-β1 level.

Objective To study the effect of body weight management on community residents with over-weight or obesity.Methods Chronic Disease Management Information System was used to establish personal health profile for 10 560 individuals with over-weight or obesity(4660 men and 5900 women,average age 58±12 years).Guide for individualized food intake,physical activity were given to these participants for an average of 9±6 months (range,1 to 32 months) with a following up.The change of body weight before and after the intervention was nalyzed.Statistical software(SPSS 12.0) wag used for the data analysis,the frequencies,rate and trend were analysised by the chi-square test,the means in quatitaitve data was analyzed by the paired t-test.P valuse for statistiacal significance is set for 0.05.Results A total of 9848 participants showed no change in body weight,although weight decrease or increase was seen in 499 and 213,respectively.Before and after the intervention,the proportion of weight remained,decrease or increase among over-weisht + central obesity individuals was 92.3%(6290/6817),5.9%(403/6817) and 1.8% (124/6817);95.5%(2888/3024),2.8%(84/3024) and 1.7%(52/3024) among the simple overweight or obesity group;and 93.2%(670/719),1.7%(12/719)and 5.1%(37/719) among the simple central obesity group,separately.Conclusions Body-weight management among central obesity individuals with over weight in communities is a more effective way of in terms of individule intervention than those individuals only with single over-weight,obesity or central obesity status.
