The effects of Panax notoginseng saponins (PNS) and verapamil(Ver)on hemo-dynamics of internal carotid artery and superior mesenteric artery were determined and compared in anesthetized Sprague ~ Dawley strain rats. PNS 30-150 mg ? kg-1 iv was shown to reduce the mean blood pressure, internal carotid arterial resistance and superior mesenteric arterial resistance by 11 % ~19%, 14%~27%,23%~ 39%respectively. Meanwhile, the mesenteric ar-terial blood flow increased.by 16%~51%. Ver showed similar reflects as PNS. The results indicated that the vasodilation effects of PNS and Ver are vascular selective, that is PNS and Ver are more potent in dilating the mesenteric artery than the internal carotid artery.

Objective To evaluate the efficacy and safety of interferon alpha (IFNα) combined with adefovir dipivoxil (ADV) for patients with chronic hepatitis B (CHB) non-responding to 24-week IFNα monotherapy.Methods Sixty CHB patients admitted to the First Affiliated Hospital of Xiamen University during 2009 and 2012 were enrolled in the study.All patients recieved IFNα monotherapy for 24 weeks and had no response.The patients were randomly divided into 3 groups by number table with 20 cases in each group.The experimental group was treated with IFNα combined with ADV,the control group 1 continued IFNα monotherapy,and the control group 2 shifted to ADV monotherapy.Virological,serological and biochemical responses were compared,and adverse reactions were observed.SPSS 19.0 software was used for data analysis.Results After 24 weeks of treatment,there was no statistical difference in HBV DNA loads,ALT levels and titers of HBeAg and HBsAg among three groups (F =0.985,0.717,0.985 and 0.717,P ＞ 0.05).And no HBeAg seroconversion was observed.After 48 weeks of treatment,the experimental group had higher HBV DNA negative conversion rate,ALT normalization rate and HBeAg conversion rate than control group 1 (x2 =10.00,3.956 and 4.800,P ＜ 0.05),but no statistically significant difference was found in HBeAg negative conversion rate (x2 =0.693,P ＞ 0.05).There was no significant difference in HBV DNA and HBeAg negative conversion rates between experimental group and the control group 2 (x2 =1.026,1.905 and 0.156,P ＞0.05),but the HBeAg conversion rate in experimental group was significantly higher than that in control group 2 (x2 =4.800,P ＜ 0.05).No HBsAg negative or serological conversion was observed,and there was no significant difference in titers of HBsAg among three groups (F =1.935,P ＞ 0.05).No adverse reaction was observed.Conclusion For patients nonresponding to IFNα monotherapy,combination of IFNα and ADV can achieve higher ALT normalization rate,HBeAg conversion rate and HBV DNA negative conversion rate,and improve the overall efficacy of CHB antiviral therapy.

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 mechanism of orindonin induced apoptosis on NB4 (Human acute promylocytic leukeamia cell line) cells. Methods: The variation of both morphology and inhibitory rate of NB4 cells were observed in culture medium with various concentrations of orindonin at different time in vitro. The activity of Caspase3 was detected before and after apoptosis occurred. Results: orindonin could increase the activity of Caspase3, inhibit the growth and cause apoptosis on NB4 cells significantly. The variations were both in time and dose dependent manner. Conclusion: Orindonin can inhibit the growth of NB4 cells and induce apoptosis. Increasing the activity of Caspase3 may be one of the most important mechanism.

The paper is to report the study of pharmacokinetics of transdermal administered nicotine in the brain of freely moving rat by using microdialysis with stable labeled isotope as internal standard. The pharmacokinetic behavior of nicotine in Sprague Dawley rat brain was investigated after intranasal administration (3.75 mg). Brain fluid samples were collected by intracerebral microdialysis with DL-nicotine as internal standard. Concentrations of nicotine and DL-nicotine in the sample were measured by HPLC-MS/MS. Main pharmacokinetic parameters were calculated and analyzed by Das 2.0 pharmacokinetic software. The recovery of nicotine and the delivery of DL-nicotine were the same. The fate of absorption and distribution was two compartment model and the values of t1/2alpha was 170.31 min, t1/2beta was 263.30 min and the AUC(0-infinity) was 2.75 x 10(5) microg x L(-1) min separately. DL-nicotine can be used to calibrate the recovery of nicotine, and the new method of stable isotope microdialysis can be used to study the pharmacokinetics of freely moving rat. It will make sense for the treatment of addiction of tobacco and provide a new thought for the research of pharmacokinetics-pharmacodynamic combination.

Objective: To investigate the apoptotic effects and its mechanisms on K562 cells caused by Interferon-alpha (INF-?) and Cytarabine (Ara-C). Methods: The variation of both morphology and inhibitory rate of K562 cells was observed in culture medium with IFN-? and various concentrations of Ara-C at different time in vitro. The variation of telomerase activity and P53 protein expression were detected before and after apoptosis occurred. Results: INF-? and Ara-C used concurrently could cause apoptosis and inhibit the growth of K562 cells as well as decrease the telomerase activity and increase P53 protein expression significantly. All these processes showed both in time- and dose-dependent manner. Conclusions: INF-? and Ara-C used concurrently can inhibit the growth of K562 cells and induce apoptosis, inhibiting the telomerase activity and increasing the expression of P53 protein may be one of the most important mechanisms.
