Objective To investigate the Toxoplasma gondii infection status in pregnant women with history of adverse preg?nancy and risk factors in Bazhou area,Hebei Province. Methods A total of 302 pregnant women with the history of adverse pregnancy were chosen as respondents(an experimental group)in the hospital from March 2012 to December 2015,and 197 pregnant women without the history of adverse pregnancy as a control group. TOX?IgG and TOX?IgM were detected by using ELI?SA in two groups. The risk factors of Toxoplasma infection were surveyed by questionnaires. Results The total positive rate of Toxoplasma antibodies was 28.15%(85/302)in the experimental group,which was significantly higher than that[9.64%(19/197)]in the control group,and the difference was statistically significant(χ2=24.76,P<0.05). The positive rates of TOX?IgM,TOX?IgG and TOX?IgM+TOX?IgG were 6.95%(21/302),18.54%(56/302),and 2.65%(8/302)respectively in the ex?perimental group,which were higher than 2.03%(4/197),7.61%(15/197),and 0%(0/197)respectively in the control group (χ2=6.07,11.67,3.76,all P<0.05). The questionnaire survey showed that the proportions of keeping pets,cutting board re?gardless,liking to eat hot pot or barbecue,eating raw meat,often eating in the restaurant in the pregnant women with Toxoplas?ma infection were higher than those in the pregnant women without Toxoplasma infection,and the differences were statistically significant(χ2=22.57,3.96,5.87,7.40,4.86,all P<0.05),and therefore,the above unhealthy habits may be important risk factors. Conclusions Toxoplasma infection could lead to adverse pregnancy outcomes. Therefore,the above?mentioned unhealthy habits should be avoided,especially during pregnancy period.

Objective To use HSV 1 tk (herpes simplex virus type Ⅰthymidine kinase)/GCV (ganciclovir) in androgen independent prostate cancer cells(C4 2,PC3) in vitro in order to provide useful basis for clinical use. Methods HSV 1 tk gene was ligated to a pN 2A retroviral vector. Recombinant DNA molecules being introduced into a packaging cell line PA317,the high titer virus producer cells (VPC) were screened.The integration and expression of HSV 1 tk gene in VPC was observed by PCR and RT PCR. VPC was co cultured with these cancer cells in the light of 1∶1,1∶2,1∶4,1∶8.Cell viability (cytotoxicity) was assessed by SRB (sulforhodamine B protein dye binding)after the first day,the third day,the fifth and the seventh day. Results The highest titer VPC producing HSV 1 tk gene was isolated. Retrovirus mediated HSV 1 tk gene therapy was effective and active against such prostate cancer cells.The best one was co culture of VPC and cancer cells at 1∶1 and the fifth day followed by GCV. Compared with C4 2, PC3 decreased remarkably.The activation of apoptosis and other ways failed to be found. Conclusions Retrovirus mediated HSV 1 tk gene therapy in Vitro directly killed the tumor cells by cytolytic activity.

Objective To investigate the effect of sevoflurane on blood pressure in patients with different ages and the optimal concen-tration of sevoflurane. Methods 60 patients underwent selective LC operation with conventional induction and sevoflurane maintenance were divided into three groups:the youth group (34 patients), the middle age group (20 patients) and the older age group (6 patients). The SBP, DBP, MAP, CETsev, number of patients, age of patients before induction and 10 min(T1), 20 min(T2), 30 min (T3), 60 min (T4) after induction were recorded. Results Fluctuate of blood pressure were in the normal range after anesthesia maintenance, and MAP were fluctuated within the range of ± 20% before induction. The age under different CETsev were of no significant difference in each time point (P>0. 05). The age composition ratio in different CETsev were of no significant difference in each time point (P>0. 05). As the time of anesthesia extended, the number of patients under 0% ~1%CETsev decreased from 35 to 11; the number of patients under 1% ~2%CETsev increased from 10 to 20;and the number of patients under 2% ~3%CETsev maintened in 14 approximately. Conclusion The effect of sevoflurane on blood pressure of different ages is approximate. 2% ~3% CETsev is the most optimal concentration during the main-tenance of anesthesia.

OBJECTIVE: To study the effect of Jianpi Huoxue Jiedu (JPHXJD) prescription on prevention of the postoperative metastasis of gastric cancer and to observe the changes of immunity and whole blood viscosity after treatment. METHODS: JPHXJD prescription and chemotherapy were administered to the treated group for 12 successive months, while only chemotherapy was given to the control group. RESULTS: The effective rate of anti-metastasis in the treated group was obviously better than that in the control group. In the aspects of enhancing Karnofsky scores, reducing whole blood viscosity and improving immunity after treatment, the treated group was better than the control group (P<0.05). CONCLUSION: JPHXJD prescription combined with chemotherapy shows apparent effect on anti-metastasis. It can improve the quality of life of the patients, lower the whole blood viscosity and improve the immunity function.
