Picrotoxin is an anatagninst of gamma-aminobutyric acid, which is an internal inhibition-transmitter in the central nervous system, Picrotoxin exerts a biphasic action on the blood pressure and heart rate in rats and cats in vivo. That is to say, in the initial stage, picrotoxin can lower the blood pressure and heart rate, and then an elevation of these two even above the original level can be observed, up to the present, from the authors limited literature, there has been no report dealing with the problem whether picrotoxin can act on an isolated heart directly.In this study, the heart of a frog was isolated and routine intubation of the heart was done for its perfusion. Physiological polyconduction instrument was inserted through a mechanical transducer to record the heart rale and myocardial contractility. A suspending glass microelectrode coupling with a microamplifier is used to record the action potential of the ventricular myocardium. Real time analysis of all the data was accomplished with a microcomputer. The dosages of picrotoxin used were 1,5, 3.0, 6.0, and 12.0 mg per kilogram of body weight.It was found that picrotcxin can directly act on the isolated frog heart. The results were as follows.1 ) Picrotoxin exerts inhibition on the special conduction system of the heart,and the A-V node and venous sinus are very sensitive. Complete or partial transmission block can be induced.2 ) It can elicit clearly a fall of the heart rate but no biphasic action can berevealed. 3) It can reduce the myocardial contractility, suggesting that the calciuminflow during the functioning period of the action potential is effected. 4 ) It can reduce the amplitude of the action potential but no effect on themaximal depolarization speed is observed, suggesting that picrotoxin islikely to affect the level of resting potential but not the action potentialin the depolarized period.

Objective:To explore the effect of group visits on health condition among follow-up patients with chronic heart failure.Methods:Totally 126 outpatient follow-up patients with heart failure were divided into intervention group and control group by random number table from 2018 to 2019. The intervention group consisted of 63 cases and control group consisted of 59 cases. The intervention lasted 6 months. The intervention group received group visits, while the control group received routine outpatient follow-up. Medication adherence, quality of life and heart failure related indicators were evaluated at baseline and after 6 months of intervention.Results:At 6 months after intervention, the scores of medication adherence, total quality of life, body, emotion and others dimensions of the intervention group were (5.79±1.38), (30.11±8.22), (12.65±5.53), (5.24±4.57) and (12.22±4.76) points.

Six months after the intervention, the heart function grade of NYHA and BNP of the intervention group were better than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The group management model can effectively improve heart failure related knowledge, self-care behaviors, heart function grade of NYHA and BNP of patients with heart failure follow-up.

Objective    To discuss the feasibility of establishment of animal model of "functional" bicuspid aortic valve with swine and observe its effect on the wall shear stress inside the aorta. Methods    Four common Shanghai White Swine with body weight between 50 kg to 55 kg were selected. Under general anesthesia and cardiopulmonary bypass, the aortic transverse incision approach was used, continuous suture with 6-0 polypropylene to align the left and right coronary valve leaflets to create a bicuspid valve morphology. After the operation, echocardiography was used to observe the aortic valve morphology and the hemodynamic changes of the aortic valve orifice. The effect on the wall shear stress inside the aorta was studied with 4D-Flow magnetic resonance imaging (MRI). Results    A total of 4 swine "functional" bicuspid aortic valve models were established, with a success rate of 100.0%. Echocardiography showed that the blood flow velocity of the aortic valve orifice was faster than that before the operation (0.96 m/s vs. 1.80 m/s). 4D-Flow MRI showed abnormally increased wall shear stress and blood flow velocity in the aorta of the animal models. After the surgery, in model animals, the maximal wall shear stress inside the ascending aorta was greater than 1.36 Pa, and the maximum blood flow velocity was greater than 1.4 m/s. Conclusion    Establishment of the animal model of "functional" bicuspid aortic valve in swine is feasible, scientific and reliable. It can be used in researches on evaluating the pathophysiological changes.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Severe muscle injury is hard to heal and always results in a poor prognosis. Recent studies found that extracellular vesicle-based therapy has promising prospects for regeneration medicine, however, whether extracellular vesicles have therapeutic effects on severe muscle injury is still unknown. Herein, we extracted apoptotic extracellular vesicles derived from mesenchymal stem cells (MSCs-ApoEVs) to treat cardiotoxin induced tibialis anterior (TA) injury and found that MSCs-ApoEVs promoted muscles regeneration and increased the proportion of multinucleated cells. Besides that, we also found that apoptosis was synchronized during myoblasts fusion and MSCs-ApoEVs promoted the apoptosis ratio as well as the fusion index of myoblasts. Furthermore, we revealed that MSCs-ApoEVs increased the relative level of creatine during myoblasts fusion, which was released via activated Pannexin 1 channel. Moreover, we also found that activated Pannexin 1 channel was highly expressed on the membrane of myoblasts-derived ApoEVs (Myo-ApoEVs) instead of apoptotic myoblasts, and creatine was the pivotal metabolite involved in myoblasts fusion. Collectively, our findings firstly revealed that MSCs-ApoEVs can promote muscle regeneration and elucidated that the new function of ApoEVs as passing inter-cell messages through releasing metabolites from activated Pannexin 1 channel, which will provide new evidence for extracellular vesicles-based therapy as well as improving the understanding of new functions of extracellular vesicles.
