RESUMEN

Objective: To explore and study the clinical usefulness of continuous dynamic recording of left cardiac function changes forevaluation the improvement in patients with chronic disease after 3 months of intensive control of individualized precision exercise overall manage program. Methods: From 2018 to 2021, 21 patients with chronic cardiovascular and cerebrovascular metabolic diseases mainly controlled by our team were selected to complete the cardiopulmonary exercise test (CPET) and Non-invasive synchronous cardiac function detector (N-ISCFD), electrocardiogram, radial pulse wave, jugular pulse wave and cardiogram data were continuously recorded for 50s.According to the titration results under CPET and continuous functional parameters monitoring, a holistic plan with individualized moderate exercise intensity as the core was developed for 3 months of intensive management, and then N-ISCFD data collection was repeatedafter signing the informed consent. All N-ISCFD data were analyzed in the 50s according to the optimal report mode of Fuwai Hospital and 52 cardiac functional indexes were calculated. The data before and after the enhanced control were compared and the paired T-test was used to statistically analyze the changes of groups. Results: Twenty-one patients with chronic diseases (16 male and 5 female) were (54.05±12.77,29~75) years, BMI (25.53±4.04,16.62~31.7) kg/m2.Comparison with baseline,the whole group analysis: ①The body weight, BMI, systolic blood pressure and diastolic blood pressure of patients were significantly decreased(P＜0.01).②CPET Peak VO2 was (64.93±24.22, 26.96~103.48) %Pred before enhanced control, and (85.22±30.31, 43.95~140.48) %Pred after enhanced control, and increased (35.09±27.87, 0.12~129.35) % after enhanced control compared with before enhanced control. The AT, Peak VO2/HR, Peak Work Rate, OUEP, FVC, FEV1, FEV3/FVC% and MVV were significantly increased (P＜0.01) and the Lowest VE/VCO2 and VE/VCO2 Slope were significantly decreased(P＜0.01).③Core indicators of left heart function:Ejection fraction was significantly increased from (0.60±0.12,0.40~0.88) to(0.66±0.09, 0.53~0.87)(P＜ 0.01), by (12.39±14.90,-12.32~41.11)%. The total peripheral resistance was significantly decreased from (1579.52±425.45,779.46~2409.61) G/(cm4·s),to(1340.44±261.49,756.05~1827.01) G/(cm4·s)(P＜0.01), by (12.00±17.27,37.79~28.61) %.The left stroke index, cardiac total power, ejective pressure and left ventricular end diastolic volumewere significantly improved (P＜0.05).The change analysis of each indicator for each patient is shown in the individualized analysis section of this study. Conclusion: Use CPET and continuous functional monitoring we can safely and effectively develop the overall program of individualized exercise in patients with chronic diseases. Long-term intensive management and control can safely and effectively significantly improve the cardiovascular function of patients. Continuous dynamic recording of changes in left and right cardiac functional parameters can be a simple way to supplement CPET to evaluate cardiovascular function.

RESUMEN

Controlled sustained-release preparation (CSRP) is a definitely important source of innovative medicines, however, its further researches and development are limited due to the complexity of Chinese medicine (CM) compositions, and a series of unclear key problems like the apparent properties from physical and chemical aspects. Combined with the CM characteristics of the multiple components and synergistic effect, a series of bottleneck problems in the preparation of CSRP were analyzed. Then the mechanism and influences of supermolecular chemical theory in the CSRP about the multiple-components overall-control were explored under the guideline of "overall control, synchronous dissolution" in CSRP, based on the previous explications about supramolecular chemistry theories and with the application of single component precision controlling technologies. The supermolecular mechanism of multi-component overall control and synchronous release of the CSRP was investigated, providing an useful academic reference for the research and development of the CSRP and laying the theoretical and technical foundation for the manufacturing process of CSRP.

RESUMEN

The study focused on the in vitro release of Buyanghuanwu (BYHW) elementary osmotic pump sustained release tablets. Its band similarity was calculated by the total quantum statistical moment. Meanwhile, in vitro release characteristics were analyzed to discuss the existence of supramolecular imprinting templates. The results show that the same imprint templates may exist in different structures of traditional Chinese medicine(TCM)'s multi-components. The BYHW sustained release tablets prepared by elementary osmotic pump can meet the objectives of "overall control, synchronous release". However, the supramolecular imprinting templates in TCM compound prescriptions should be further explored, the overall and synchronous release of different components was controlled through imprinting templates, so as to seek the more suitable sustained release preparation technology for multiple components of TCM, and make it in line with the characteristics of TCM.
