Objective To investigate the effects of serum levels of leptin, IGF-1, BDNF and inflammatory markers in patients with post-stroke depression(PSD). Methods By using Hamilton rating scale for depression (HAMD) ,46 patients with post-stroke depression were recruited and 50 patients without depression as the control group. Two weeks after the onset of stroke, serum levels of leptin, insulin growth factor(IGF-1), hs-CRP, intracellular adhesion molecule (ICAM-1) and brain-derived neurotrophic factors (BDNF) were measured by enzymelinked immunosorbent assay(ELISA). Results The levels of leptin and IGF-1 in patients with PSD were significantly higher than that of the control group (( 57.4 ± 14.32) ng/ml vs (17.53 ± 11.62) ng/ml, P = 0. 002;(120.86 ±28.66) ng/ml vs (66.5 ± 17.51) ng/ml, P=0. 004 respectively). The serum levels of leptin and IGFI were positively correlated with the HAMD score(r=0. 724, P＜0. 01; r=0. 641, P＜0. 01 respectively). There was no significant differences in the levels of hs-CRP((2.3 ±0.42) mg/dl vs (2.2 ± 0.28) mg/dl, P= 0. 767),ICAM-1 (( 182.6 ± 50.27) ng/ml vs (178.7 ± 51.14) ng/ml, P = 0. 812) and BDNF(( 25.8 ± 8.35) ng/ml vs (24.2 ±7.48)ng/ml, P = 0.580)in the two groups. Conclusion The serum levels of leptin and IGF-1 may be associated with post-stroke depression and may be the markers of PSD in the old stroke patients.

Objective To study calcium chelator BAPTA-AM antagonize the cellular oxidative stress induced by hydrogen peroxide ( H2 O2 ) and to explore the effect of calcium ion on the cell degeneration mediated by NLRP3.Methods The SHSY5Y cell model of oxidative stress was made by hydrogen perox-ide,then the cell model was treated with calcium ion carrier A23187 or BAPTA-AM,a higher efficiency cal-cium chelating agent.The cells were divided into 4 groups:H2O2 treatment group,H2O2+A23187 group, H2 O2+A23187 +BAPTA-AM group and control group.NLRP3 protein was detected by Western blot,and Caspase-1 and IL-1βwere detected by ELISA.Results NLRP3 expression was significantly increased in cells treated by hydrogen peroxide(P<0.05) .The NLRP3 protein continued to increase, and the expression of Caspase-1((57.1±19.2)pmol/L) and IL-1β((484.2±49.5)pg/ml) protein was also increased signifi-cantly in cells treated by A23187,and the difference had statistically significant for caspase-1 or IL-1βin H2O2+A23187 group compared with those in control group(Caspase-1:(26.8±12.9)pmol/L,IL-1β:(326.9 ±52.1) pg/ml) (P<0.05, P<0.01) .NLRP3,Caspase-1 and IL-1βwere all significantly reduced after adding a high-er efficiency calcium chelating agent BAPTA-AM.Conclusion Calcium overload is likely to enhance the oxidative stress induced by hydrogen peroxide and engender neurodegeneration mediated by NLRP3 inflammasome.

Objective To develop a simple model for the noninvasive diagnosis of liver fibrosis in patients with chronic hepatitis B and to testify its diagnostic value. Methods One hundred and ninety patients with chronic hepatitis B who had undergone liver biopsy were divided into 2 groups:one for developing the model(n=110) and one for validation(n=80). Histological staging of liver fibrosis,assessed blindly and independently by 2 pathologists,was determined according to Scheuer fibrosis score.Twenty markers involved in the study were analyzed initially in the estimation group to derive a predictive model to discriminate the stages of fibrosis.The model created was then assessed with receiver operating characteristic curve(ROC)analysis. It was also applied to the validation group to test its accuracy. Results Haptoglobin(HPT),γ-glutamyl transpeptidase(GGT)and platelet were identified by logistic regression analysis as independent factors of fibrosis. A model developed from the above three markers was established to predict the stage of fibrosis(S). In ROC analysis,the area under curve(AUC) for identifying S≥1,S≥2,S≥3 and S=4 was 0.832,0.835,0.820 and 0.843 respectively. The model had a similar AUC in the vatidation group without statistically significant difierence. Using a cut-off of ＜0.18, significant fibrosis (S≥2)could be excluded in 27 patients of the total patient population(negative predictive value 90%).Similarly,applying a cut-off ≥0.70,significant fibrosis could be identified correctly in 67 patients of the total patient population(positive predictive value 82.7%).The model had a high level of diagnostic value in patients with HBeAg-positive chronic hepatitis B as well as in patients with HBeAg-negative chronic hepatitis B(AUC for identifying S≥2,0.857 vs 0.802). Restricting biopsy to patients with intermediate scores(≥0.70 and ＜0.18) may prevent liver biopsies in 58.4% of the patients while maintaining 84.7% accuracy. Conclusions A model including HPT,GGT and platelet is a simple and reliable index for predicting significant fibrosis in patients with HBeAg-positive chronic hepatitis B as well as in patients with HBeAg-negative chronic hepatitis B.

In this work, a fast and efficient microwave-assisted extraction (MAE) method was developed to extract main bioactive alkaloids from lotus plumue. To optimize MAE conditions, three main factors were selected using univariate approach experiments, and then central composite design (CCD). The optimal extraction conditions were as follows: methanol concentration of 65%, microwave power of 200 W, and extraction time of 260 s. A high performance liquid chromatography–diode array detector (HPLC–DAD) method was established to quantitatively analyze these phytochemicals in different lotus plumule samples and in different part of lotus. Chromatographic separation was carried out on an Agilent Zorbax Extend-C18 column (4.6 mm×150 mm, 3.5 μm). Gradient elution was applied with the mobile phase constituted with 0.1%triethylamine in water (A) and acetonitrile (B): 40%?70% B at 0?8 min, 70%?100% B at 8–9 min, 100% B for 2 min, and then equilibrated with 40%B for 2 min.

OBJECTIVE:To investigate the condition of ESBLs produced by E.coli isolated from urinary tract and the drug resistance of ESBLs-producing E.coli.METHODS:The identification of bacteria was performed using ATB-Expression analysator(France);the susceptibility test was performed using K-B method,and ESBLs were detected using disc diffusion confirmatory test.RESULTS:The detection rate of ESBLs-producing E.coli was 31.8%.All(100%)of the 107 strains of ESBLs-producing E.coli were sensitive to imipenem,however,in which different degree of resistance to other antibiotics was noted.The resistance rate was significantly higher in ESBLs-producing strains than in non-ESBLs-producing strains.CON-CLUSION:In view of the high antibiotic resistance of ESBLs-producing E.coli,great importance should be attached to the detection of the ESBLs.Antibiotics should be used rationally based on the results of susceptibility test.
