ABSTRACT
“Stasis generating deficiency” is considered to be an important pathogenesis of recurrence after catheter ablation of atrial fibrillation （AF）. Blood stasis is commonly seen after ablation together with various pathogens such as phlegm-fire， qi stagnation and retained fluid， and will lead to depletion of zang-fu （脏腑） organs and then the failure of the nourishment of the heart. Therefore， it is advised to emphasize on the importance of considering zang-fu organs depletion caused by blood stasis and various excess pathogens in dealing with the recurrence after catheter ablation. The method of dissolving stasis and supplementing deficiency simultaneously has been proposed before catheter ablation， and it is critical to calm heart and dissolve stasis， regulate and supplement internal deficiency so as to prevent the postoperative recurrence of AF. For recurrence of AF after ablation， attention should be paid to dissolving stasis and dispelling pathogens， regulating vessels and supplementing deficiency， as well as the excess pathogens such as stasis binding and phlegm fire， stasis binding and qi stagnation， stasis binding and retained fluid， and the depletion of zang-fu organs should be considered. Accordingly， the method of dissolving stasis and dispelling phlegm， subduing fire and unblocking vessels， regulating and supplementing heart and spleen； dissolving stasis and move stagnation， unblocking qi and blood， supplementing lung and boosting qi； dispelling stasis and dissolving rheum， warming yang and activating blood， consolidating the root and nourishing heart can be used respectively， so as to treat both the root and the branch simultaneously.
ABSTRACT
Coronary microcirculation disorder after myocardial ischemia reperfusion （MIR） is a prominent problem in the treatment of coronary heart disease. According to the physiological commonality between “collaterals-sweat pore qi and fluid” and coronary microcirculation， and the evolution of the course of MIR， it is believed that “heart collateral stasis obstruction， sweat pore constraint and block” is the cause of coronary microcirculation disorder. The evolution of the pathogenesis can be divided into three periods. During the myocardial ischemia period， the pathogenesis is heart collaterals obstruction and sweat pores empty， while during the ischemia reperfusion period， it is internal formulation of deficiency wind， spasms of collaterals or slight heart collaterals obstruction； in the coronary microcirculation disorder period， sweat pores constraint and block， constraint transforming into heat， qi and fluid failing to diffuse are the pathogenesis. The corresponding treatment principle is assisting dredge with supplementation， and supplementing deficiency to dispel stasis； treating wind and blood simultaneously， and extinguishing wind to arrest convulsion； clearing heat and cooling blood， and diffusing qi and unblocking qi and fluid. Moreover， it is recommended to treat the heart and lungs simultaneously， and regulate the heart and liver at the same time.
ABSTRACT
Objective:To investigate the pelvic floor muscle functioning of persons with pelvic floor dysfunction (PFD) at different ages in order to provide a reference for clinical treatment.Methods:A total of 580 PFD patients were divided into group A ( n=163, ≤29 years old), Group B ( n=161, 30-39), Group C ( n=114, 40-49), Group D ( n=128, 50-59) and Group E ( n=14, ≥60 years old). All were given a surface electromyography (sEMG) examination of their pelvic floor muscles. Average sEMG amplitude and its variability were recorded in the pre-resting and post-resting stages. The maximum sEMG amplitude and its rise time and recovery time during rapid contraction of pelvic floor muscles were recorded. Average sEMG amplitude and variability were also recorded during slow muscle contraction. The observations were correlated with the age. Results:Significant differences among the 5 groups were found in all of the measurements. Spearman correlation analysis showed that age was positively correlated with the variation in the sEMG amplitudes in the pre-resting stage, with the rise time and with the recovery time. Age also correlated with the maximum sEMG amplitude in the rapid stage, the variation of the EMG amplitude in the slow-muscle stage, and the EMG amplitude in the post-resting stage. But it was negatively correlated with the average sEMG amplitude during pelvic floor contraction.Conclusions:The stability and coordination of the pelvic floor muscles gradually deteriorates with age. The rate of activation and recovery become slower, with prolonged recruitment, slower response and poor excitability.
ABSTRACT
Objective To investigate the effect of oxytocin on the expression of MKP-1 level in the hippocampus of post-traumatic stress disorder rats.Methods Eighteen SD rats were randomly divided into the control group,administration group and the experimental group with 6 rats in each group.The administration group and the experimental group were treated with internationally recognized single prolongation stress (SPS) method to stimulate the rats in order to establish PTSD models.The 14-day oxytocin intervention was given to rats of the administration group after the SPS stimulation within 8 hours.And the behavioral changes of rats were observed by open-field test and Morris water maze test.The changes of MKP-1 mRNA in the hippocampus of rats were detected by real-time quantitative PCR (qRT-PCR),and the levels of MKP-1 Protein in the hippocampus of rats were detected by Western Blot.Results (1) Compared with the model group (2.50± 1.05 and 22.16±7.14),the times of the standing and crossing grid section quantities in the open-field test in the administration group(5.16± 1.17and 32.83±5.71) and control group (6.67±2.16 and 39.83± 4.62) significantly decreased (P＜0.05).Morris water maze showed that the incubation of the model group was markedly prolonged (P＜0.05) compared with that of the administration group,while in spatial probe test,the incubation period of the rats in administration group was prolonged,and the number of wearing stage decreased (P＜0.05).(2) Compared with the administration group (1.30±0.03),the expression of MKP-1 mRNA in hippocampus of rats in model group (4.04±0.46) was notably up-regulated (P＜0.05).And the protein level of MKP-1 in model group(1.95±0.68) was also increased compared with that in administration group (1.46±0.27) (P＜0.05).Conclusions Oxytocin can protect the learning and memory ability and reduce the stress-related performance of rats via regulating the expression of MKP-1.
