Parkinson's disease （PD） is a complex neurodegenerative disease involving multiple systems and neurotransmitters. Due to the high clinical heterogeneity of PD，it is urgent to establish a comprehensive and long-term traditional Chinese medicine （TCM） management model. In this paper，the conceptual framework of full-cycle management of PD is preliminarily constructed：based on the evolution of the pathophysiological mechanisms of protein deposition and neurotransmitter disorder in PD，the three-stage syndrome characteristics of the prodromal stage （predominant healthy Qi with subtle pathogenic factors），the early clinical stage （declining healthy Qi with growing pathogenic factors） and the middle and late stages （overwhelming pathogenic factors with deficient healthy Qi） are longitudinally described. Through the syndrome differentiation of visceral manifestations，the etiology and pathogenesis of PD motor and non-motor symptoms were comprehensively analyzed，while the matching treatment methods and prescriptions were inferred，and the modular scheme of the combining main symptoms，accompanying symptoms and secondary symptoms was proposed. The conceptual gap of TCM regarding motor complications （'variable syndrome'） and PD-related hyperpyrexia syndrome （'critical syndrome'） was explained. This framework reflects the characteristics of combination of disease and syndrome and overall constant motion，and provides new theories and research ideas for individualized and whole-process management of PD in TCM.

Objective:To explore the application of typical case combined with practice teaching in the pediatric clinical teaching.Methods:A total of 80 clinical interns majoring in pediatrics who practiced in the Affiliated Hospital of Jining Medical University between September 2019 and January 2020 were selected as the research subjects, and they were randomly divided into observation group ( n=41) and control group ( n=39). The control group adopted conventional teaching while the observation group were given typical case combined with practice teaching model. After 16 weeks of training, the theoretical knowledge, practical operation [direct observation of procedural skill (DOPS) evaluation, and mini-clinical evaluation exercise (Mini-CEX)] and overall performance were analyzed in the two groups of students. SPSS 19.0 was used for t test, chi-square test and rank sum test. Results:After the internship, the theoretical scores of common pediatric diseases, clinical disease characteristics, etiopathogenesis, treatment regimen and complications were enhanced in the two groups, and the above scores in observation group were higher than those in control group ( P<0.05). Besides, the DOPS scores and Mini-CEX scores of the two groups were increased, and the scores were higher in observation group than in control group ( P<0.05). Furthermore, the overall excellent rate of the observation group was 87.80% (36/41), which was higher than 69.23% in control group (27/39). Survey found that the number of interns who believed that the teaching regimen could deepen the knowledge mastery degree, increase the internship interest and improve the comprehensive ability, internship efficiency and clinical thinking ability was more in observation group than in control group. Conclusion:Typical case combined with practice teaching can effectively deepen the interns' understanding of theoretical knowledge of clinical pediatrics, improve the practical operation ability and arouse the interest in learning.

Objective: To observe the hemodynamic change characteristics of left ventricle and evaluate left ventricular systolic function in patients with chronic heart failure (CHF) via vector flow mapping(VFM). Methods: Sixty-two patients with CHF(CHF group) were selected as case group and were divided into three groups (B, C, D) according to the American College of Cardiology Foundation and the American Heart Association (ACC/AHA ) recommended stages.Sixty healthy volunteers were selected as control group. The left ventricular circulation parameters (vortex quantity, vortex area, circulation) and energy loss (EL) of the apex, mid, and basal segments in different groups were compared in all the systolic phases. Left ventricular ejection fraction (LVEF) was calculated by biplane Simpson method, and the correlation was analyzed with the parameters of circulation and EL. Results: ①In the phase of isovolumetric contraction (IVC) and slow ejection (SE), compared with the control group, the levels of EL were increased in mid and basal segments (P<0.01 or P<0.05) in CHF group. The vortex area and circulation during IVC and rapid ejection (RE) were higher in CHF group than those in the control group (P<0.01 or P<0.05). As for SE, only vortex quantity was higher in CHF group than that in the control group (P<0.05). ②In CHF group, EL were increased at stage B and stage C than those in the control group (P<0.05), and EL were decreased at stage D than those in the control group ( P<0.05). Meanwhile, there was decreased tendency of EL in CHF group with the increase of ACC/AHA stages. ③The circulation during IVC of phase D was higher in CHF group than that in the control group (P<0.05), the vortex area during RE was greater in CHF group than that of the control group and stage B (P<0.05). ④EL was positively correlated with LVEF at basal segment of IVC(r=0.615, P<0.001). The vortex area during RE, circulation during IVC and RE were negtively correlated with LVEF (r=-0.598, -0.594, -0.623; all P<0.001). Conclusions VFM technology can quantify the left ventricular hemodynamic changes of patients with CHF in the systolic phase, and shows its relationship with left ventricular systolic function, to provide objective basis for grading of CHF and also provide objective quantitative indicators for clinical treatment and curative effect evaluation.
