Objective: To explore heart rate variability (HRV) and arrhythmia in patients with resistant hypertension.
Methods: Our work included 3 groups:Resistant hypertension (RH) group, n=39, Non-resistant hypertension (NRH) group, the hypertension could be controlled by 1-3 medications, n=42 and Control group, composed of 40 healthy subjects. The 24h ambulatory blood pressure and electrocardiogram were monitored, the time-domain of HRV and arrhythmia parameters were compared among 3 groups which including standard deviation of all normal RR intervals (SDNN), standard deviation of the average normal RR intervals for all 5-min segments (SDANN), the mean of standard deviation of all 5-minute RR intervals (SDNN Index), the root mean square of the differences between adjacent R-R intervals (rMSSD) and the percentage of adjacent R-R intervals varied by more than 50 ms (pNN50).
Results: Compared with Control group, both RH and NRH groups showed decreased time-domain HRV parameters, all P<0.05. Compared with NRH group, RH group had the lower time-domain HRV parameters, all P<0. 05, while the rMSSD was similar between 2 groups (t=-1.5048, P=0.1364). The rates of arrhythmia in both RH and NRH groups were higher than Control group. The incidences of premature atrial contraction and atrial tachycardia were higher in RH group than NRH group, P<0.05, while the premature ventricular contraction, ventricular tachycardia and A-V block were similar between 2 groups, all P>0.05.
Conclusion: RH patients had decreased HRV and increased arrhythmia, especially with the higher incidence of atrial arrhythmia.

Objective　To investigate the effect of a new cloned full length gene, C2 gene which encodes a translation initiation factor, on cell cycle and the relationship between C2gene and apoptosis. Methods　Construct a eukaryotic vector carrying the full length of C2 gene, then transfected it into a gastric cell line-SGC7901 cells and gained cells expressing C2 protein transiently or stably. Test the expression of C2 protein and the change of cell cycle of the transfected cells using the flurescence activatied cell sorting(FACS) and the changes of their ultra structure electromicroscopically. Results　The C2 gene eukaryotic expression vector was successfully constructed. FACS showed the C2 protein expression ratio of transfected cells was 32.3%, while the empty control group was 0.9%. The test of cell cycle showed that there was appeared apoptosis peak in transiently or stably transfected cells. The apoptosis cells can be seen electromicroscopically among the C2 transfected cells. Conclusions　C2 gene transfection can lead SGC7901 cells to apoptosis, but the mechanism has to be further study.

Objective To investigate the changes of chemokines related to dendritic cells in liver and spleen in rats with hepatic carcinoma treated by radiofrequency ablation (RFA),and to explore the mechanism of anti-tumor responses to RFA.Methods Forty healthy SD rats with established animal model of hepatic carcinoma were randomly divided into control group (n=10),RFA 7d group (n=16) and RFA 14d group (n=14).The rats of control group were killed without treatment.The other rats were killed in 7d and 14d after RFA treatment respectively.Spleen and liver tissue around the ablation area or around the tumor were taken out.The expressions of macrophage inflammatory protein (MIP)-1a in liver tissue and MIP-3β in spleen were analyzed by ELISA.Results The expression of MIP-1a in liver tissue was (232.92±54.5B)ng/L in control group,which enhanced to (499.38±15.14)ng/L and (495.90±9.94)ng/L in RFA 7d and 14d groups respectively.There were significant differences between control and RFA 7d group,control and RFA 14d group(P＜0.05).The expression of MIP-3βin spleen was (70.08±2.67) ng/L in control group,which enhanced to (151.57±48.48)ng/L and (154.57±18.25)ng/L in RFA 7 d and 14 d groups respectively.There were significant differences between control and RFA 7 d group,control and RFA 14 d group (P＜0.05).Conclusions The expressions of MIP-1a in liver tissue and MIP-3β in spleen increase significantly after RFA.These changes will promote recruitment and migration of dendritic cells and may contribute to the anti-tumor responses after RFA.

Objective To analyze the Doppler indices of uterine artery at 11-16 weeks normal gestation. Methods Two hundred and ninty-seven normal pregnant women were consecutively recruited to take routine ultrasound examination at 11-16 weeks' gestation. According to gestational week, they were divided into 6 groups (11-11+6 weeks, 12-12+6 weeks, 13-13+6 weeks, 14-14+6 weeks, 15-15+6 weeks, 16-16+6 weeks). According to the location of placenta, they were divided into 3 groups (central placenta, right placenta, left placenta). Finally, the pregnant women were divided into 5 groups (RI<0.60 group, 0.60-0.69 group, 0.70-0.79 group, 0.80-0.85 group and ≥ 0.85 group) according to resistance index (RI). Doppler indices of uterine artery were measured in each case. Results (1) The PIm, RIm, S/Dm values (the mean PI, RI, S/D values of bilateral uterine artery) were decreased with the progress of pregnancy, but the difference of the RIm, S/Dm were not significant. Only the decrease of PIm after 15 weeks was significant (P<0.05). The mean PIm of each group was:11 weeks 1.96±0.39, 12 weeks 1.94±0.45, 13 weeks 1.79±0.43, 14 weeks 1.79±0.36, 15 weeks 1.51±0.43, 16 weeks 1.50±0.30. (2) The PI, RI, S/D values of uterine artery with placenta attached were lower than the other side. In the left placenta group, bilateral RI difference was-0.04 (t=-3.095, P=0.005), bilateral PI difference was -0.24 (t=-3.232, P=0.004), bilateral S/D difference was-1.00 (t=-2.965, P=0.007);in the right placenta group, bilateral RI difference was 0.04 (t=6.159, P=0.000), bilateral PI difference was 0.43 (t=6.614, P=0.000), bilateral S/D difference was 2.05 (t=6.378, P=0.000);in the middle placenta group, bilateral RI difference was 0.02 (t=4.150, P=0.000), bilateral PI difference was 0.14 (t=4.475, P=0.000), bilateral S/D differencewas 0.54 (t=4.376, P=0.000). (3) According to the RI, incidence rates ofα-notch detected:in<0.60 group both sides were 0;in 0.60-0.69 group, left uterine artery was 0.08, right uterine artery was 0.08;in 0.70-0.79 group, left uterine artery was 0.34, right uterine artery was 0.31;in 0.80-0.85 group, left uterine artery was 0.65, right uterine artery was 0.72;in≥0.85 group, left uterine artery was 0.81, right uterine artery was 0.87. Conclusion The uterine artery Doppler indices of 11-16 weeks maybe a reliable and non-invasive method for examining uteroplacental perfusion.

Objective:To study the scavenging activity of macroporous resin isolate of gynostemma pentaphyllum on free radical DPPH. Methods:The extract of gynostemma pentaphyllum via water boiling and precipitation with ethanol was separated by macro-porous resin respectively eluted by water, 40% ethanol and 80% ethanol to obtain the corresponding isolates. The antioxidant activity of the three isolates was determined by free radical DPPH systematic method, and the results were compared with that of gallic acid and ascorbic acid. Results: The 50% inhibitory concentration on free radical DPPH of the three isolates was 0. 081 2, 0. 028 7 and 0. 541 0 g·L-1 ,respectively. The 40% ethanol isolate had the highest saponins concentration. Conclusion:The macroporous resin i-solate with different solvent all shows antioxidant activity and the 40% ethanol isolate has the strongest effect, suggesting saponins may be the active substances for the lipid-lowering, hypoglycemic and free radical scavenging activities.
