Objective To study the influence of hydroxyethylstarch 200/0.5 on hemodynamic and coagulation in hemodilution for paediatrics patients(AHH).Methods 64 paediatrics patients who would receive AHH were selected.All patients were randomly divided into HES group(received HES 200/0.5)and control group(received sodium lactate Ringer's),32 patients in each group.Hemodynamic efficacy and coagulation indexes were recorded before AHH(T0),30 min post-AHH(T1) and 60 min post-AHH(T2).Results There were no sinificant differences in MAP,HR,CVP,INR,APTT,CT and FIB compared with T0 or between groups.RBC,Hct and Hb were significantly lower compared with T0,but no significant differences were observed between groups.CI and PT were significantly higher compared with T0,but no significant differences were observed between groups.Conclusion There were no negative effects on hemodynamic efficacy and coagulation in paediatrics patients treating with HES 200/0.5.

Objective To investigate the safety and effectiveness of laparoscopic surgery for early ovarian cancer. Methods Selected 90 early-stage ovarian cancer patients from January 2010 to December 2014 in Zhejiang Cancer Hospital as research subjects, and randomly divided into laparoscopic surgery group and laparotomy group. Then compared the age, BMI, ovarian cancer diameter, ovarian cancer staging, blood loss, operative time, surrounding or﹣gan damage, albumin difference before and after surgery, postoperative ventilation time, postoperative hospital stay, interval of postoperative to the first chemotherapy, postoperative fever cases, follow-up time, postoperative complica﹣tions, postoperative recurrence and postoperative death in two groups. Results Blood loss and operative time of la﹣paroscopic surgery group was less than that of laparotomy group (P< 0.05). Albumin difference before and after surgery of laparoscopic surgery group was less than that of laparotomy group (P< 0.05), postoperative ventilation time and interval of postoperative to the first chemotherapy of laparoscopic surgery group was less than that of la﹣parotomy group (P< 0.05), the incidence of postoperative fever and postoperative complications of laparoscopic surgery group was less than that of laparotomy group (P< 0.05), the recurrence rate and postoperative mortality rate of laparoscopic surgery group were slightly higher than that of laparotomy group, but the difference was not statisti﹣cally significant (PP> 0.05). Conclusion Laparoscopic surgery for early-stage ovarian cancer has a relatively good safety and efficacy. Laparoscopic surgery has advantages over open surgery in improving early ovarian cancer intra﹣operative situation and postoperative situation.

A 2 L tubular photobioreactor (PBR) was designed, and hydrogen production by Rhodospirillum rubrum uptake hydrogenase deficient mutant in this PBR under artificial illumination condition (including continuous illumination and light/dark cycle condition) and natural day/night cycle was investigated, respectively. Hydrogen production by R. rubrum uptake hydrogenase deficient mutant under artificial illumination lasts five days, and hydrogen yield under continuous illumination and light/dark cycle (12 h:12 h) reaches 5752 mL/PBR ? 158 mL/PBR and 5012 mL/PBR ? 202 mL/PBR, respectively. Under natural day/night cycle, hydrogen production lasts 6~10 days and the maximal hydrogen yield of R. rubrum reaches 2800 mL/PBR with the optimal light intensity of about 30000~40000 Lux. Hydrogen production under natural day/night cycle condition was lower than that under artificial illumination, however, it would be a promising technology of hydrogen production due to low cost and ease of operation of hydrogen production system.

Objective To study the role of Schwann cells apoptosis in the pathogenesis of experimental autoimmune neuritis(EAN) in TNF receptor Ⅰ knock out(TNFR Ⅰ-/-)mice.Methods For induction of EAN,TNFRⅠ-/- and wild type C57BL/6 mice were immunized by subcutaneous injection into the back with the peripheral nerve P0 protein peptide 180-199;clinical scores of EAN were assessed and scored immediately before immunization(day 0) and thereafter every other day until day 46 post immunization(p.i.).On day 22 p.i.,Schwann cells were collected from the two groups and cultivated in vitro.The expressions of Fas and Annexin-Ⅴ(Annexin-Ⅴ+/PI-)on Schwann cells from TNFRⅠ-/-and wild type EAN were detected by flow cytometry.Results More light clinical signs of EAN were observed in the TNFRⅠ-/-mice(1.50?0.19) than in wild type mice(1.90?0.16);the percentage of Fas expression on Schwann cells was significantly decreased in TNFRⅠ-/-mice(88.03%?1.40%)as compared with wild type mice(94.70%?1.53%)(P

In order to get more nutrition from outside the erythrocyte,new channels were induced by malaria par-asite.These channels play an important role in physiology of the parasitized cell.They are of interest both as potential targets in their own right and as potential drug targeting routes capable of mediating the entry of cytotoxic drugs into the app-ropriate compartment of the infected cell.It is hoped that this new anti-malarial strategy will help to create a sustainable anti-malaria-drug-development portfolio for the treatment of malaria.
