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.

BACKGROUND: Cardiopulmonary resuscitation (CPR) is a kind of emergency treatment for cardiopulmonary arrest, and chest compression is the most important and necessary part of CPR. The American Heart Association published the new Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care in 2010 and demanded for better performance of chest compression practice, especially in compression depth and rate. The current study was to explore the relationship of quality indexes of chest compression and to identify the key points in chest compression training and practice.METHODS: Totally 219 healthcare workers accepted chest compression training by using Laerdal ACLS advanced life support resuscitation model. The quality indexes of chest compression, including compression hands placement, compression rate, compression depth, and chest wall recoil as well as self-reported fatigue time were monitored by the Laerdal Computer Skills and Reporting System.RESULTS: The quality of chest compression was related to the gender of the compressor. The indexes in males, including self-reported fatigue time, the accuracy of compression depth and the compression rate, the accuracy of compression rate, were higher than those in females. However, the accuracy of chest recoil was higher in females than in males. The quality indexes of chest compression were correlated with each other. The self-reported fatigue time was related to all the indexes except the compression rate.CONCLUSION: It is necessary to offer CPR training courses regularly. In clinical practice, it might be better to change the practitioner before fatigue, especially for females or weak practitioners. In training projects, more attention should be paid to the control of compression rate, in order to delay the fatigue, guarantee enough compression depth and improve the quality of chest compression.

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.
