Objective To evaluate the diagnostic value of serum retinol binding protein (RBP) on the early stage of type 2 diabet‐ic nephropathy by receiver operating characteristic(ROC)curve .Methods According to urinary albumin(mAlb)/urinary creatinine (UCr) ratio ,155 patients with type 2 diabetes were divided into simple diabetic mellitus group ,early stage of diabetic nephropathy group ,and clinical stage of diabetic nephropathy group ,while healthy people were recruited randomly during the same period as con‐trol group .RBP test were performed by using immunoturbidimetry .The diagnostic value of RBP on in the early stage of type 2 dia‐betic nephropathy were evaluated by analyzing the ROC curve .Results The concentration of serum RBP in the early stage of dia‐betic nephropathy was significantly higher than that in the group of simple diabetic mellitus and control group (P<0 .05) ,the area under the ROC curve of RBP in serum was 0 .770 ,and the cutoff value was 40 .95 mmol/L ,while the sensitivity and the specificity were 81 .0% and 95 .2% .Conclusion RBP was a good marker in detecting early renal damage .

·Uveitis is an inflammation of any or all parts of the uveal tract including the iris, ciliary body and the choroid. Despite current advances in diagnosis and management, visual loss occurs in 35%-45% of patients with uveitis. The etiopathogenesis of uveitis remains unknown; it may be associated with environmental and immunogenetic factors. Many studies have demonstrated polymorphisms in major histocompatibility complex (MHC) genes may determine involvement in uveitis. Recently polymor-phisms in non-MHC genes, including cytokine and che-mokine genes, have been reported to play important roles in the pathogenesis of uveitis. This article reviewed the advances in the studies on cytokine and chemokine gene polymorphisms associated with uveitis.

BACKGROUND:In the cytotoxicity test of the mussel adhesive protein dressing for wound healing, because of positive charge properties of the protein, when extracting ratio is 1:9, the cel s exhibit poly-group phenomenon that results in errors in the cytotoxicity test of mussel adhesive protein samples.
OBJECTIVE:According to the existing standards, to improve the leaching proportion and pretreatment of mussel adhesive protein dressing for wound healing based on the special properties and working condition of mussel adhesive protein.
METHODS:(1) Extract method:Extract solution of mussel adhesive protein dressing was prepared with mussel adhesive protein dressing and cel medium at extracting ratios of 1:9 and 1:131. Then, L929 cel s were cultured in extract solutions of mussel adhesive protein dressing, natural latex and high-density polyethylene, respectively. (2) Method of direct contact:Distil ed water, solutions of mussel adhesive protein dressing, dimethyl sulfoxide and cel medium were used to culture L929 cel s.
RESULTS AND CONCLUSION:When the extracting ratio was 1:9, the cel s agglomerated which is not suitable for cytotoxicity test. When the extracting ratio was 1:131, flocculated sediment and cel aggregation disappeared, the cytotoxicity test results showed no cytotoxicity with higher reliability. Direct contact method showed the samples had no cytotoxicity. The extract method with adjusted extracting radio or direct contact method can be applied to test the in vitro cytotoxicity of mussel adhesive protein dressing for wound healing.

Objective We sought to compare the ability of MEWS score,APACHE Ⅱ score and combination of the two scoring systems to predict the prognosis of patients in emergency medical department.Methods During January to March 2014,640 patients in emergency medical department who met the criteria were set as the research object.The patients admission was the starting point for clinic observation.The relevant data were collected for carrying on the MEWS and APACHE Ⅱ ratings,tracking the patients' prognosis.The corresponding predictors for prognosis of patients such as sensitivity,specificity,positive predictive value,negative predictive value and ROC curve by MEWS score,APACHE Ⅱ score and combination of the two scoring systems were compared.Results The area under the receiver operating characteristic curve was 0.93,0.79 and 0.93 with MEWS score,APACHE Ⅱ score and combination of the two scoring systems.The comparison of either of the two scoring systems showed significant difference.When death was named as the prediction factor,the sensitivity,specificity,positive predictive value and negative predictive value were 76.92%,91.70%,51.02%,97.23% for MEWS score; 83.08%,62.80%,20.15% and 97.04% for APACHE Ⅱ score; 92.31%,86.43%,43.48% and 97.58% for combination of the two scoring systems.Conclusions Combination of the MEWS and APACHE Ⅱ scoring systems can be used to predict the prognosis of patients in emergency medical department.It posesses high sensitivity,specificity,positive predictive value and negative predictive value,which indicating a high predictive capability.

Induced pluripotent stem cell is a landmark in the stem cell study field, which has rapidly developed in the past 10 years.By obtaining induced pluripotent stem cells from somatic cell, and then differentiating into cardiomyocyte, various cardiomyocyte disease models could be established,which can be used for research of disease mechanisms, drug screening and gene therapy.This review introduces the successfully established cardiomyocyte disease models from human induced pluripotent stem cells, and points out the problems and prospects.
