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 change of dendritic cells (DCs) in rats with hepatic carcinoma treated by radiofrequency ablation (RFA),and to explore the mechanisms of anti-tumor immune response to RFA. Methods Forty healthy SD rats with established animal model of hepatic carcinoma were randomly divided into control group (n = 10) ,RFA 7 d group (n = 16) and RFA 14 d group (n = 14). The rats of control group were killed without treatment. The other rats were killed in 7 d and 14 d after RFA treatment respectively. Peripheral blood, liver tissue around the ablation area and spleen were taken out. The OX62,OX6,CD86 of DCs were analyzed with flowcytometry. Results ①OX62 cells accounted for (0.45 ± 0.19)% of mononuelear cells in peripheral blood in control group. The account of OX62 cells increased to (0.78 ± 0.30)% and (1.53 % 0.80)% 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). ②OX62 cells accounted for (18.91 ± 4.58)% of mononuclear cells in liver tissue around the tumor in control group. The account of OX62 cells increased to (24.49 ± 4.59)% in RFA 7 d group (P<0.05). The expression of OX6 on DCs in liver tissue was (15.29 ± 4.59)% and increased to (34.2 ± 11.62)% and (39.18 ± 9.14)% in RFA 7 d and RFA 14 d group respectively (P<0.05). ③OX62 cells accounted for (11.69 ± 4.39)% of mononuclear cells in spleen in control group which increased to (15.10±2.37)% in RFA 14 d group (P<0.05). Conclusions The precursor DCs in peripheral blood and DCs in liver and spleen increased significantly after RFA. The expressions of OX6 on DCs in liver and spleen increased after RFA. RFA can promote the differentiation and maturation of DC. The increased function of antigen presenting may contribute to the anti-tumor responses after RFA.

Objective To evaluate the effects of an intervention programme of health education and life style modification on postmenopausal osteoporosis women. Methods A total of 120 postmenopausal osteoporosis women were enrolled in this one-year randomized controlled follow-up study and assigned to the intervention group ( Group A, n = 60) or the control group ( Group B, n = 60). Both groups were treated with alendronate sodium. In Group A, education program was performed once a season in the form of face-to-face consultation or group session. In Group B, no additional intervention was used. The primary outcome was patients' compliance in follow-up. The secondary outcomes were change in bone mineral density (BMD).BMD was measured by dual-X-ray absorptiometry (DXA) on lumbar spine and hip at baseline and 12 months after the intervention. Results After one-year intervention,51 subjects in Group A and 38 in Group B completed the follow-up. Groups A showed better compliance. BMD on lumbar spine and hip was significantly increased in both groups when compared with baseline. The changes of BMD on lumbar (0.042+0.067 vs 0.026±0.070,P=0. O29) or Words region (0.029 +0. 129 vs 0.023±0. 143,P=0. 041 ) showed statistical significance between the two groups. Conclusion For alendronate sodium treatment, health management ensures the effectiveness of the therapy and improves the compliance of the patients.
