Chinese Journal of Obstetrics and Gynecology 2015;(6):446-451
Objective To study the significance of circadian gene Period2 expression in epithelial ovarian cancer tissues and the effect of gene overexpression on the growth of ovarian cancer xenografts in nude mice. Methods Twenty-two cases of ovarian cancer paraffin specimens in the First Hospital of Shanxi Medical University (ovarian cancer group) were chosed during Jau. 2010 to Dec. 2013, including 8 cases of stageⅠ, 8 cases of stageⅡ, and 6 cases of stageⅢ, while 6 cases of benign ovarian epithelial tumor paraffin specimens were selected as control (benign tumor group). Period2 gene were detected by real-time quantitative PCR and western blot methods in different stages of ovarian cancer tumor tissues. Established theovarian cancer xenografts in nude mice with ovarian cancer cell line SKOV3, and they weredivided into 3 groups (n=8), including the recombinant plasmid group, empty plasmid group and control group. Using gene transfection technique to transfer Period2 gene into tumor tissues, tested the expression of Period2 mRNA in tumor tissues by real-time quantitative PCR after transfection into all nude mice, monitoredthetransplant tumor growth and calculating the tumor inhibition rate,detected the antiapoptotic gene BRE, apoptosis related tumor necrosis factor receptor (TNFR1) andtumor suppressor gene NIX in tumor tissues by real-time PCR and western blot in different groups. Results (1)The expression level of Period2 mRNA in tumor tissues amongovarian cancer group stageⅠ,ⅡandⅢwere respectively 2.59±0.50, 0.47± 0.08 and 0.42 ± 0.08, but benign tumor group was 6.59 ± 1.05. The expression level of Period2 protein in ovarian cancer group stage Ⅰ,Ⅱ and Ⅲ were respectively 0.835 ± 0.087, 0.412 ± 0.035 and 0.199 ± 0.031, while benign tumor group was 0.874 ± 0.094. The expression level of Period2 mRNA and protein in benign tumor group was higher than those in ovarian cancer group stageⅠ,ⅡorⅢ(P<0.01). With ovarian cancer stage increased, the expression of Period2 mRNA and protein were decreased or absent (P<0.05).(2)Two weeks after transfection, the expression level of Period2 mRNA in recombinant plasmid group tumor tissue was significantly higher than those in the empty plasmid group or the control group (6.11±0.56 vs 0.50±0.09 vs 0.44 ± 0.08, respectively;P<0.01), the transplanted tumor volume of recombinant plasmid group was significantly less than those in empty plasmid group or the control group[ (486±70) mm3 vs (835±106) mm3 vs (846 ± 110) mm3, respectively;P<0.01], the tumor inhibition rate of the recombinantin plasmid group was as high as 42.9%, that was significantly higher than those in the empty plasmid group and the control group (3.8% and 0, respectively;P<0.05).(3)The expression level of BRE mRNA and protein in transplanted tumor tissues in the recombinant plasmid group were significantly lower than those in empty plasmid group and the control group;the expression level of TNFR1 and NIX were significantly higher than those in the empty plasmid group and the control group (all P<0.05). Conclusions Period2 mRNA and protein expression are absent in ovarian cancer of advanced stage. Transfection and stable expression of Period2 gene could slow down the growth of ovarian cancer, and the tumor inhibition rate could be significantly increased. Period2 gene may promote ovarian cancer cells apoptosis through inhibition of BRE gene expression and promoting TNFR1, NIX gene expressionto exert anti-tumor effect.

Chinese Journal of Emergency Medicine 2008;17(11):1152-1157
Objective To investigate the effects of different cardiopulmonary resuscitation (CPR) qualifies under Q-CPR control on hemodynamics and aerobic metabolism in pigs with cardiac arrest. Method After eighteen pigs (mass [ (30+ 1) kg] were anesthetized,a Swan-Ganz catheter was positioned through the right femoral vein and linked with a continuous cardiac output monitor. An electrode cable was positioned into right ventricle through left internal jugular vein. Then different catheters were positioned in the arteriae aorta, carotid artery and fight atrium successively. Ventricular fibrillation (VF) was induced by a programmed electrical stimulation equipment. All animals underwent 4 minutes of untreated VF and then were randomly assigned to either standard CPR or nonstandard CPR. A Philips HeartStart MRx Monitor/Defibrillator was used to ensure qualifies of chest compression (e.g., depth, rate and chest recovery) by Q-CPR technology. Pigs in standard CPR group were treated with standard compression with a compression rate of 100 beat/min, a compression-ventilation ratio of 30:2, and a depth of with 38~51 mm with 100% decompression. Pigs in nonstmdard CPR group were treated with nonstandard compression with a depth of 60%~70% of standard depth with unsatisfactory decompression. Defibrillations were administered after 9 minutes of compressions and vetilations. Cardiac output (CO), mean aortic pressure (MAP) and coronary perfusion pressure (CPP) were recorded at different periods. Oxygen delivery (DO2) and oxygen consumption (VO2) were calculated according to blood gas analysis. At last,number of the survivals was recorded.Data were calculated by SPSS 11.5 statistics software. Statistical analysis was performed using Chi-Square Test and two independent samples t testing. Results The return of spontaneous circulation (ROSC) achievement ratio with nonstandard CPR was 28.6% and with standard CPR was significantly greater (90.9%, P=0.013).Hemodynamics (e. g., CPP, CO and MAP) and systemic oxygenation with standard CPR were much better. Conclusions In this animal model of cardiac arresr in pigs, standard CPR could improve hemodynarmics by increasing CPP and CO. And standard CPR could beneficial aerobic metabolism by increasing DO2 and VO2. As a result, ROSC achievement ratio of pigs with standard CPR was much greater.
