Isolation and identification of two new compounds from Semen Persicae / 药学学报

Five compounds were isolated from the ethyl acetate fraction of Semen Persicae by using various chromatographic methods, including ODS, Sephadex LH-20, HPLC and semipreparative HPLC. Their structures were identified by 1D-NMR, 2D-NMR, HR-ESI-MS, UV, IR, circular dichroism (CD) and ECD calculation techniques: (2R,3R)-5,7,4′-trihydroxy-3′-methoxy-3-formylflavan-3-ol-5-O-β-D-glucopyranoside (1), (7R,8S)-dihydrodehydrodiconiferyl 6″-benzoyl alcohol-9-O-β-D-glucopyranoside (2), (7R,8S)-dihydrodehydrodiconiferyl alcohol-9-β-O-D-glucopyranosid (3), 2-methoxy-4-(2-propenyl)-phenyl-O-β-D-glucopyranoside (4), 2-[4-(3-hydroxypropyl)-2-methoxyphenoxy]-propane-1,3-diol (5). Compound 1 and 2 are new compounds, and compounds 3-5 were obtained from Prunus davidiana (Carr.) Franch. for the first time.

Two new terpene glycosides from the Alpiniae Oxyphyllae Fructus / 药学学报

Two undescribed terpene glycosides and two compounds were isolated from the n-butanol fraction of Alpiniae Oxyphyllae Fructus by using various chromatographic methods, including MCI Gel, Sephadex LH-20, ODS, silica gel and semi-preparative HPLC. The structures of the isolated compounds were identified by spectroscopy methods (1D, 2D NMR, UV, IR, MS, etc.), and the absolute configuration of the compound 1 was determined by ECD calculation and acid hydrolysis. Compounds 1 and 2 are new compound, and compounds 3 and 4 were isolated from Alpiniae Oxyphyllae Fructus for the first time.

Effect of Neuromuscular Joint Facilitation Ankle Joint Pattern on Balance in Healthy Young Men / 中国康复理论与实践

Objective:To compare the effects of neuromuscular joint facilitation (NJF) or isotonic muscle training on dynamic and static balance in healthy young men. Methods:October, 2019, twelve students of Capital Medical University School of Rehabilitation Medicine (aged 20 to 29) were evaluated the balance indexes of single leg standing on stable support with eyes closing and single leg standing on unstable support with eyes opening with BIODEX Balance Tester, and measured 10-meter walking time and Timed 'Up and Go' Test (TUGT) after non-intervention, NJF ankle joint pattern and ankle flexion and extension. Results:The balance indexes, 10-meter walking time and TUGT were the least after NJF (F > 18.941, P < 0.01). Conclusion:NJF ankle joint model can improve the dynamic and static balance ability of human body more effectively than isotonic contraction training alone.

Effect of Kinesio Taping at Knee on Position Sense and Lower-limb Function / 中国康复理论与实践

Objective:To observe the effects of Kinesio Taping and kneepad on position sense of knee in healthy young adult male. Methods:In September, 2019, 20 healthy adult male aged 21 to 27 were selected. They were measured the joint angle error in angle reproduction test, and tested with functional reach test (FRT), 10-meter walking time (10MWT), and Timed "Up and Go" Test (TUGT) under follow four conditions: non-intervention, simple Kinesio Taping, simple kneepad, and both Kinesio Taping and kneepad. Results:For the angle error, it was the most under non-intervention, and the least under simple Kinesio Taping (F = 61.260, P < 0.001). For FRT, there was no significant difference among all the conditions (F = 1.793, P = 0.988). For 10MWT, it was the least under simple Kinesio Taping (F = 23.817, P < 0.001). For TUGT, it was the most under non-intervention (F = 19.865, P < 0.001). Conclusion:Kinesio Taping can improve position sense of knee, as well as walking, without further benefit along with kneepad.
