Objective To research the effect of ulinastatin on T-cytoimmunity in patients with infertility undergoing laparoscopic surgery. Methods Forty patients scheduled for receiving laparoscopic surgery were equally randomized into two groups, ulinastatin group (Group U) and control group (Group C). Ulinastatin was given to patients in the Group U at a dose of 20 × 104 U before anesthetic. No ulinastatin was given to patients in the Group C. Patients′venous blood samples for T-lymphocyte subset (CD3+,CD3+CD4+,CD3+CD8+) and CD3+CD4+/ CD3+CD8+ ratio calculation were collected before the surgery (T0) and at 0 h (T1),1st day (T2),3rd day (T3) after the surgery. Results CD3+ had less difference at T1~3 compared with T0 in the Group C but raised obviously at T2~3 in the Group U. CD3+CD4+ were only raised at T3 compared with T0 but raised obviously at T2~3 in the Group U. CD3+CD8+ were raised obviously at T2~3 compared with T0 in the Group C but had less difference in the Group U. CD3+CD4+/CD3+CD8+ had less difference at T1~3 compared with T0 in the Group C but raised obviously at T3 in the Group U. Conclusion The application of ulinastatin in laparoscopic surgery could significantly produce protective effect on T-cytoimmunity.

Objective Using Sevoflurane in general anesthesia in cesarean operation , to evaluate change of stress response by monitoring maternal plasma concentrations of HSP70 and the expression of HSP70 in the placenta tissue and provide an ideal and basis of safty and effectiveness in obstetric general anesthesia. Methods Sixty caesarean operation puerperas undergoing general anesthesia in women and children′s hospital of Guangdong province were selected and randomly divided into the sevoflurane group (S group) and the propofol group (P group) through random number table, each group had 30 cases. We tested materal blood concentration and expression of HSP70 in placenta tissue. Results HSP70 concentration (when) in the P group was significantly higher than that before surgery (P < 0.05); Comparing with the group S at the same time point, the difference was statistically significant (P < 0.05); In expression of HSP70 in placental tissue, P group was obviously higher than the S group (P < 0.05), Conclusion Sevoflurane used in general anesthesia for cesarean operation is safe and effective , which can reduce the concentration of HSP70 in maternal blood and expression of HSP70 in placental tissue.
