Chinese Journal of Digestion 2009;29(7):479-480
Objective To study the efficacy of esomeprazole in treatment of asthmatic patients with gastroesophageal reflux (GER) symptoms. Methods Sixty-nine asthmatic patients with GER symptoms were received esomeprazole 40 mg daily and mosapride 5 mg three times daily for 8 weeks. After that, esomeprazole 20 mg and mosapride 5 mg daily were prescribed to the patients for sustained therapy. The effect of asthma control was evaluated according to criteria for asthma control level made by Chinese Society of Respiratory Disease Asthma Group. All patients were followed up for 2 years.Results It was revealed that complete asthma control was achieved in 39 patients, well control in 25 patients and the total effective rate was 93 %. Asthma-control medication was stopped in 42 patients,dose reduced to 1/2 in 18 patients and continuous therapy in 9 patients. During 2 years follow-up, 58 patients were benefited from the treatment with complete asthma control and seldom attack of asthma was seen in 11 patients with reduced frequency and severity. Conclusion The symptoms of asthmatic patients with GER symptoms can be improved by esomeprazole, so that their quality of life areimproved.

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.

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.
