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 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.

Objective To explore the application and significance of multiple clinical pathway training oriented teaching model in clinical teaching of laboratory diagnostic. Methods Totally 50 medical students enrolled in the Second Military Medical University from September to December in 2015 were divided into experimental group and control group. The course consists of theoretical teaching and experi-mental operation. The pathway group (n=25) were introduced into multiple clinical pathway training oriented teaching method. The theoretical teaching was carried out bysimulation examination application, simulation interpretation and simulation diagnosis and treatment, while the experimental course was carried out by using video teaching combined with actual operation. The control group was taught by traditional teaching method using slide teaching and operation display. The theoretical test including case study and operational skill tests were performed among students in both groups after 10 class hours training . The satisfaction questionnaires were conducted to evaluate the effectiveness and satisfaction of teaching guided by clinical pathway. Differences were compared with independent sample t testing using GraphPad Prism 5.0 statistical software. Results The medical records about professional theoretical test including case study and opera-tional skill test in the pathway group were superior to those in the control group with significant statistical difference (both P<0.05). The records of medical students were (81.84±7.21), (42.00±2.79) in the pathway group and (76.24 ±6.98), (37.00 ±3.71) in the control group. The questionnaire result showed that the pathway group's satisfaction was high, especially with the theoretical knowledge andsceneteaching (higher than 80％). The pathway group believed that multiple clinical pathway training helped to improve learning interest and clinical thinking ability . Conclusions Multiple clinical pathway training oriented teaching model is helpful for the medical students to achieve the basic idea of clinical pathway, improve the profes-sional ability, enhance the interest of learning and the quality of teaching, standardize teaching and promote teaching and learning.

Objective To investigate the modulation role of autophagy in radiation-induced cell death by detecting the response of src kinase activity and autophagy in HEK293 cells irradiated with different dose of α-particle.Methods HEK293 cells were irradiated by contral group (0 cGy) a low dose group (10 cGy) and high dose group (300 cGy) α-particles.Molecular probe 2',7'-dichlorofluorescin (DCFHDA) was used to detect the cell ROS.The src kinase activity and endogenous protein level of LC3Ⅰ/Ⅱ were monitored by Western Blot.Cell death rate of irradiated cells pretreated with autophagy inducer of rapamycin was tested by flow cytometry.Results Compared with control group,the ratio of LC3Ⅰ/Ⅱ decreased (t =4.07,P ＜ 0.05) and the percentage of cells with GFP-LC3 punctuate dots increased (t =12.29,P ＜0.05) under 10 cGy irradiation,indicating the induction of autophagy.On the contrary,the ratio of LC3Ⅰ/Ⅱ increased (t =2.93,P ＜ 0.05) and the GFP-LC3 morphology had no obvious change under 300 cGy irradiation.The cellular ROS level reached to the maximum value at 4 h postirradiation.Both 10 cGy and 300 cGy irradiation could elevate the ROS level (t =17.93,22.88,P ＜0.05),whereas the amplitude of elevation of 300 cGy irradiation was higher than that of 10 cGy irradiation (t =15.76,22.66,14.22,P ＜ 0.05).Compared with control group,the 419th site of tyrosine residue in src kinase manifested hyper-phosphorylation (t =5.66,P ＜0.05) under 10 cGy irradiation whereas it had hypo-phosphorylation under 300 cGy irradiation (t =4.67,P ＜ 0.05).Treatment of cells with DMSO could partly restore the impact on src kinase activity under high or low dose irradiation.Pre-treating the cells with autophagy inducer rapamycin could reduce cell death under 300 cGy irradiations (t =12.14,P ＜ 0.05).Conclusions High or low dose of α-particles irradiation could inhibit or activate src kinase and autophagy system,respectively.ROS mediated the response of src kinase activity and autophagy system induced by irradiation.Modulation of autophagy could desensitize cell responses to irradiation.

Objective To observe the effect of somatostatin on liver function in patients after splenectomy combined with de-vascularization.Methods The clinical data of 48 patients with liver cirrhosis,portal hypertension and esophageal varices were retro-spectively analyzed,26 cases (somatostatin group)were used somatostatin after splenectomy combined with devascularization,and the other 22 cases (control group)were not used.The changes of serum albumin (Alb),alanine aminotransferase (ALT),aspartate transaminase (AST),prothrombin activity (PTA)and total bilirubin (TBIL)was observed.Results All patients recovered well af-ter surgery,and no deaths occurred.However,ALT,AST and TBIL of using somatostatin group were significantly reduced than those of control group(P <0.05),Alb and PTA were also improved significantly (P <0.05).Conclusion The combination of som-atostatin can not only reduce postoperative portal pressure,control of bleeding,but also to be significantly promote recovery of liver function.
