Objective To test the effects of restuscitation with air or oxygen on the blood gas and cerebral superoxide dismutase (SOD) concentration in neonatal rats with experimental intrauterine asphyxia. Method Seventy-seven neonatal rats were randomly (random number) divided into three experimental groups: sham operation group (SHAM), air resuscitation group (AR), and oxygen resuscitation group (OR). In groups AR and OR, animal models of intrauterine asphyxia were established and then resuscitated with air (AR) or oxygen (OR) for 30min. Comparison was made between groups including the mortality 0 hour after resuscitation, and the levels of blood gas and cerebral SOD concentrations 0 h, 6 h and 24 h after resuscitation. Results Mortality of neonatal rats in SHAM group, AR group and OR group were 0 (0/24), 0 (0/26) and 3.7% (1/27), respectively (P >0.05). The average levels of blood PaO2 in OR group and AR group 0 h after resuscitation were (69.2 ± 8.2)mmHg and (55.5±10.3) mmHg,respectively (P=0.004). Blood pH and PaCO2 and BE levels in OR group 0 h after resuscitation were not significantly different from those in AR group (P>0.05). Blood pH, PO2, PCO2and BE levels in OR group were also not significantly different from those in AR group 6 h and 24 hours after resuscitation. The average concentrations of cerebral SOD in OR group 0 h and 6 hours after resucitation were (38.3±9.8) U/mgprot and (8.6±3.6) U/mgprot, and those in AR group were (53.8± 10.6) U/mgprot and (13.0±4.6) U/mgprot, respectively (P = 0.003, 0.04). The cerebral SOD concentration in OR group 24 hours after resuscitation was not significantly different from that in AR group (P>0.05). The cerebral SOD concentrations in SHAM group 0 h,6 h and 24 hours after resuscitation were much higher than those in OR group and AR group (P<0.05). Conclusions Resuscitation with air is as good as pure oxygen in neonatal resuscitation, in respect of early mortality and improvement of acidosis in neonatal rats after intrauterine asphyxia. Resuscitation with air will generate less radical oxygen species than pure oxygen in neonatal rats after intrauterine asphyxia.

[Objective] To explore the in-vitro determination method for the recovery rate of sinomenine in microdialysis probe and to investigate the influencing factors. [Methods] The recovery rate of sinomenine was detected by concentration difference method (by gain and by loss) and zero-net flux method. [Results] The recovery rate detected by increment method was as the same as that by decrement method; the recovery rate had no correlation with the sinomenine concentration in the solvent. Sinomenine recovery assessed by concentration difference method had a good intra-day stability and intra-day reproducibility. Sinomenine concentration and recovery in the solvent could be determined accurately by zero-net flux method. [ Conclusion ] Microdialysis sampling can be used for the pharmacokinetic study of sinomenine and decrement method (ie. retrodialysis) can be used for the determination of recovery rate of sinomenine.

Background and purpose:Cytokine-induced killer (CIK) has both the advantages of T lympho-cytes’ powerful anti-tumor activity and NK cells’ tumor killing capacity without MHC restriction. It could directly kill tumor cells, regulate and enhance immune function, without damaging the structure and functions of the immune sys-tem. Its effects on the treatment of malignant solid tumors has been widely recognized. This study aimed to evaluate the anti-proliferation effects of CIK cells obtained and cultivated from lung cancer patients’ lymph nodes. Meanwhile, the safety of clinical transfusion was observed.Methods:The peripheral blood and lymph nodes of 6 surgery patients with lung cancer from Shanghai Chest Hospital were used to cultivate CIK cells for 14 days. The phenotypes of CIK cells were detected by lfow cytometry. The anti-proliferation activities of CIK cells on A549 lung cancer cells were detected by CCK8 assay. The morphological changes of CIK cells were observed by invert microscope. The expression of CEA level and adverse events were evaluated after CIK transfusion.Results:The proportion of CD3+CD56+T lymphocyte in two groups were both more than 30%. The CCK8 assay showed that the suppression rate of lymph nodes group was higher than that of peripheral blood group at each effect/target ratio(P<0.05). The adverse effect of CIK transfusion was mild and tolerable. The expression of CEA level decreased in patients.Conclusion:Lymph nodes of surgery patients with lung cancer can be used for cultivation of CIK cells. The anti-tumor activity of CIK isolated from lymph nodes is better than that of CIK cells cultivated from peripheral blood. Preclinical experiments showed high safety.
