OBJECTIVETo observe the effect and mechanism of curcumin derivative B06 on kidney from rats with hyperlipidemia and type 2 diabetes.

METHODSThirty five male SD rats were randomly divided into five groups(n = 7): the normal control group, high-fat group, high-fat + B06-treatd group, diabetic group, diabetic + B06-treated group. After fed with high-fat diet for 4 weeks, the later two groups were in- jected with streptozotocin intraperitoneally to induce type 2 diabetes mellitus. B06-treated groups were given B06 by gavage at a dosage of 0.2 mg/kg . d for 8 weeks. After the treatment, the serum creatinine, blood urea nitrogen and uric acid were detected biochemically, the morphology of kidney was observed with light and transmission electron microscopy, the expression of collagen fibers was observed with Masson staining, the protein expression of collogen IV and fibronectin in kidney were determined by Immunohistochemistry.

RESULTSIt was showed that the levels of the serum creatinine and blood urea nitrogen elevated significantly in diabetic group. In high-fat and diabetic groups, increased glomerular mesangial matrix and collagen fiber and thicken glomerular basal membrane were observed under light microscopy, swelling and fusion of foot process were found under electron microscope; increased green matrix within glomeruli was observed under Masson staining. collogen IV and fibronectin protein expression were significantly enhanced in high-fat group and diabetic group. After B06's intervention, the levels of serum creatinine and blood urea nitrogen were decreased in diabetic groups, the morphological change of kidney was obviously relieved, Collogen IV and fibronectin protein expression reduced.

CONCLUSIONCurcumin derivative B06 exerts a protective effect on kidney in type 2 diabetic rats, reduced expressions of collogen IV and fibronectin, inhibition of the accumulation of extracellular matrix and glomerular mesangial proliferation, and then prevention of renal fibrosis may be the mechanism.

AIM:To observe the changes in heme oxygenase-1(HO-1) expression in the lung after ischmia-reperfusion of hind limbs in rats.METHODS:Hind limbs ischemia was made by clamping infrarenal aorta with a microvascular clip and lung injury was made by following reperfusion. Lung tissue was obtained from the animals subjected to sham operation, 4 h ischemia without reperfusion and 4 h, 8 h, 16 h, 24 h, 48 h reperfusion following 4 h ischemia. The levels of HO-1 mRNA and protein were measured at different times by Northern blot and Western blot. Immunohistochemistry technique was used to determine the cell types responsible for limb ischemic reperfusion induced HO-1 expression. RESULTS:After ischemia-reperfusion of limbs, HO-1 mRNA increased by 4 h, reached a peak at 16 h, and returned toward baseline at 24-48 h. This time course correlated with increased HO-1 protein. Immunohistochemical studies showed HO-1expressed in a variety of cell types, including the airway epithelium, alveolar macrophages and vascular smooth muscular cells. There were no positive signals in sham group and ischemia group both in mRNA levels and protein levels. CONCLUSION:The expression of HO-1 in the lung is not induced by limb ischemia or sham operation, but induced by limb reperfusion after ischemia in rats.

Objective To evaluate the performance of HbA1C in diagnosis of pre-diabetes in Chinese adolescents.Methods A total of 933 students(aged 13-16 year,46.5% female)without known history of diabetes were selected from junior and senior middle schools in Liaoyang city.HbA1C and fasting plasma glucose(FPG)levels were determined in all participants.Pre-diabetes was diagnosed as according to 2010 American Diabetes Association (ADA)criteria[HbA1C 5.7%-6.4%,FPG(5.6-6.9)mmol/L].The individuals with HbA1C ≥5.7% underwent oral glucose tolerance test(OGTT)and were classified into impaired glucose tolerance(IGT)and impaired fasting glucose(IFG)according to 1999 World Health Organization(WHO)criteria.The performance of HbA1C in diagnosing pre-diabetes by the new criteria was evaluated by the traditional OGTT results based on receiver operating characteristic(ROC)curves.Results Among all participants,213(22.8%)individuals were diagnosed as prediabetic subjects.72.3% of individuals with pre-diabetes were identified by HbA1C alone,23.0% by FPG alone,and only 4.7% by both tests simultaneously.The ROC curve for HbA1C to identify impaired fasting glucose diagnosed by new criteria had an area under the curve(AUC)of 0.50 without statistical significance(P = 0.97).Of the 164 participants with HbA1C 5.7% -6.4%,68 individuals received OGTT,among which 18 subjects were diagnosed as IGT(n= 14)or IFG(n = 4).The ROC curve for HbA1C to identify pre-diabetes diagnosed by OGTT had an AUC of 0.53,without statistical significance(P = 0.69).Conclusion In Chinese adolescents,HbA1C is not suitable for diagnosis or screening of pre-diabetes.

Objective To establish the proper review rules for the microscopic screening of urine analyzed by UF-1000i automatic urinalysis work station (composed of UF-1000i urine flow cytometer and AX-4030 urine dry chemical analyzer).Methods A total of 2 839 random urine samples were collected at Chinese People′s Liberation Army General Hospital from September 2009 to February 2010, and were analyzed using UF-1000i urinalysis work station.The parameters obtained from UF-1000i and AX-4030 included RBC, WBC, CAST and ERY, LEU, PRO.After analysis by urinalysis work station, each urine sample was examined microscopically by two technologists using double-blind method.The average results got from the two technologists were regarded as the judging criterion.Based on the criterion, the review rules for the 2 839 urine samples tested by urinalysis work station were created and adjusted, and the true positive rate, false positive rate, true negative rate, false negative rate and review rate of these review rules were calculated.After that, 299 randomly selected urine samples were tested to validate these review rules.Omission diagnostic rate and review rate were used to assess the clinical practicability of the review rules.Results Thirty seven rules for microscopic review and twenty seven rules without further microscopic examination were set up based on six parameters using UriAccess 3.0 Software.The microscopic examination result was taken as the judging criterion, the consistency rate of these rules was 81.11%(2 311/2 839), the true positive rate was 40.51%(1 150/2 839), the false positive rate was 16.17%(459/2 839), the true negative rate was 41.00%(1 164/2 839), the false negative rate(omission diagnostic rate) was 2.43%(69/2 839) and the review rate was 18.28% (519/2 839).Additional 299 urine samples were assayed using UriAccess3.0 software to further verify these review rules.The consistency rate was 82.27%(246/299), the true positive rate was 36.12%(108/299), the false positive rate was 16.39%(49/299), the true negative rate was 46.15%(138/299), the false negative rate(omission diagnostic rate) was 1.34%(4/299), the review rate was 19.06%(57/299). The 4 false negative samples selected by these review rules did not come from the nephropathy department or the urology department.Microscopic results of RBC and WBC form these 4 samples ranged 3-8 cells/HP. Thus, these review rules could avoid the missed diagnosis of those patients with severe renal dysfunction.Conclusion The review rules established from this study for the UF-1000i urinalysis work station can effectively detect abnormal urine samples and improve the efficiency and the quality of urinalysis in routine clinical practice.
