Objective To compare the therapeutic effects and side effects of cisplatin-S-1 (CS) program and docetaxel-cisplatin-S-1(DCS) program on patients with malignant gastric tumor who were treated by laparoscopic gastrectomy.MethodsA total of 67 patients in our hospital from January 2010 to June 2013 were included in this study,of which 33 cases accepted cisplatin-S-1 program (CS group),34 cases accepted DCS program (DCS group).The related side effects including diarrhea,nausea and acute upper respiratory infection,change of routine blood tests,blood biochemical index,and death caused by chemotherapy were analyzed.The related index of surgery including operation time,blood loss,recovery time of gastrointestinal function,pain incidence,hospital stay,lymph nodes resection success rate,postoperative infection,obstruction,intestinal emptying delays were recorded.Meanwhile,the 3-year survival rate after operation and postoperative 3-year recurrence rate between the two groups were compared.Results There was no significant difference in operation time,intraoperative blood loss,postoperative recovery time of gastrointestinal function,the lymph nodes resection success rate,the incidence of postoperative pain,as well as the length of hospital stay,postoperative infection rate,and complications such as obstruction and intestinal emptying delays between the two groups(P>0.05).And there was no significant difference in chemotherapy-related complications between the two groups(P>0.05).But the postoperative 3-year survival rate and postoperative 3-year recurrence rate of DCS group was better than those of the CS Group(P<0.05).Conclusion There is no significant difference in complications and surgery-related index between the two preoperative chemotherapy.However,the DCS programs have more advantages in therapeutic effects.

Objective To investigate the effects of Morroniside on H2O2-induced oxidative injury in SH-SY5Y neuroblastoma cells.MethodsSH-SY5Y cells were pre-incubated with Morroniside(1,10,and 100 μmol/L)for 24 h prior to exposure to H2O2(500 μmol/L)for 18 h.The content of reactive oxygen species(ROS),nitric oxide(NO),glutathione(GSH)were determined.ResultsPretreatment the cells with Morroniside(10 and 100 μmol/L)lowered H2O2-induced ROS release by 37%(P<0.01)and 27%(P<0.05)versus H2O2,and NO release in a dose-dependent manner by 31%(P<0.05),53%(P<0.01)versus H2O2.Morroniside(1,10,and 100 μmol/L)increased GSH level in cells treated with H2O2 in comparison with cells exposed only to H2O2,respectively.ConclusionMorroniside shows neuroprotection effect against H2O2-induced oxidation injury in SH-SY5Y cell.

Neural stem cells are a category of cells with self-renewal and differentiation potential. Proliferation and differentiation of neural stem cells have closely relation with growth factor, cell factor, environmental signal, and so on. In recent years, evidence indicates that neural stem cells possessing multipotency naturally occur in adult brain. The found of adult neural stem cells have changed the theory that central nervous system cannot regenerative. Chinese Traditional Medicine can effectively induce adult neural stem cells to proliferate and differentiate, opening up unprecedented direction in the research for the treatment of nerve regeneration, and showing great potency for curing cerebral ischemic injury.

A UPLC method has been developed in the current investigation for simultaneous determination of nine chemical markers of Bletilla striata, 4-hydroxymethylphenyl beta-D-glucoside, blestroside, dactylorhin A, militarine, dihydrophenanthrene 5, gymnoside V, dihydrophenanthrene 1, benzylphenanthrene 3 and gymnosides IX. Separation was performed at 45 degrees C on an ACQUITY UPLC BEH C18 column (2.1 mm x 150 mm, 1.7 microm) with a gradient solvent system of acetonitrile-water as the mobile phase. The flow rate was 0.3 mL x min(-1), the detection wavelength was 280 nm. The results showed that the nine chemical markers could be well resolved and that in the selected linear range, all calibration curves of the nine chemical markers showed good linearity (r > or = 0.999 3). The recoveries (n = 6) were in the range of 98.15% - 102.2% and RSDs were between 2.1% - 3.6%. The data suggested that the developed UPLC-UV method had good reproducibility, robustness, and accuracy, which was suitable for the quality control of Bletilla striata. Applications of the method showed that the nine chemical markers had higher contents in the wild B. striata than in the cultivated ones.
