Textual research on classical prescriptions in Mongolian medicine / 中国中药杂志

Mongolians have a long history of using prescriptions, which can be classified into four stages as follows: the germination and experience accumulation stage before the 13 th century, the theoretical formation stage from the 13 th to 16 th century, the rapid development stage from the 17 th to 20 th century, and the leaping development stage from the mid-20 th century to the present. The prescriptions from the ancient classical or representative medical books have always been used by Mongolian physicians for generations, and they are still in use due to the definite curative effects. In 2008, the Notice on Issuing the Supplementary Provisions to the Registration and Management of Traditional Chinese Medicine(TCM) described that China has attached more importance to the excavation and development of classical prescriptions. As stipulated in the Law of the People's Republic of China on Traditional Chinese Medicine, the classical prescriptions should be those available in ancient TCM classics and still in wide use, with exact curative effects, distinct features, and obvious advantages. This paper expounded the historical formation and development of classical prescriptions in Mongo-lian medicine, introduced the five most influential ancient medical books revealing the formation and development of these classic prescriptions, and traced the origin of such classical prescriptions as Wenguanmu Siwei Decoction, Shouzhangshen Bawei Decoction, Jianghuang Siwei Decoction and summarized the origin, development history and characteristics of classical prescriptions in Mongolian medicine, aiming to provide a reference for their further research and development.

A new biflavone from Dysosma versipellis / 药学学报

This study was conducted to investigate the chemical constituents in the root of Dysosma versipellis (Hance) M. Cheng. The constituents were isolated by silica gel, lichroprep RP-C18 and pharmadex LH-20 column chromatography and the IR, MS, NMR, 2D-NMR spectroscopic analysis were employed for the structural elucidation. Ten compounds were isolated from the 95% ethanol extract of Dysosma versipellis, their structures were elucidated as dysoverine D (1), dysoverine F (2), dysoverine A (3), podoverine A (4), α-peltatin (5), rutin (6), kaempferol-3-O-β-D-glucopyranoside (7), quercetin-3-O-β-D-glucopyranoside (8), kaempferol (9) and quercetin (10). Compound 2 is a new compound, and compounds 1 and 3-6 were isolated from this plant fo r the first time.

Left ventricular functional changes of stunned myocardium during perioperation of coronary artery bypass graft surgery / 中国地方病学杂志

ObjectiveTo evaluate the functional changes of stunned myocardium before and after coronary artery bypass graft(CABG) treatment,and clear the meaning of revascularization which CABG has brought to patients with diffused vascular changes.MethodsA total of 36 patients with 99％ diffused coronary artery stenosis in left anterior descending branch underwent non-pump CABG treatment in the Department of Cardiothoracic Surgery the First affiliated hospital of Harbin Medical University.Real-time three-dimensional echocardiography (RT3DE) was repeatedly performed 1 week before operation and 10 days,1 month,and 3 months after CABG.Regional diastolic volumes,systolic volumes,ejection fractions,regional stroke volume to global diastolic volume and the values of abnormal segments before and after CABG were studied.ResultsOne week before operation and 10 days,1 month and 3 months after CABG,the differences of volumes between groups in the last phases of diastole and systolic were statistically significant in anterior wall basement segment,anterior septal basement segment,anterior wall intercalary segment,anterior septal intercalary segment,anterior wall of apex cordis and septation of apex cordis(F =3.51,3.55,4.08,4.05,2.98,3.01,all P ＜ 0.05; F =4.51,4.55,4.08,3.00,2.96,2.99,all P ＜ 0.05).The values of the six segments mentioned above,3 months after operation[(6.74 ± 1.23),(6.64 ± 1.21),(6.02 ± 1.10),(5.95 ± 1.09),(5.82 ± 1.06),(5.10 ± 0.93)ml; (2.74 ± 0.50),(2.69 ± 0.49),(2.51 ± 0.46),(2.32 ± 0.42),(2.36 ± 0.43),(2.03 ± 0.37)ml] were compared with those of 1 week before operation[(8.33 ± 1.52),(8.20 ± 1.50),(7.43 ± 1.36),(7.36 ± 1.34),(7.19 ± 1.31),(6.29 ± 1.15)ml; (4.94 ± 0.90),(4.85 ± 0.88),(4.53 ± 0.83),(4.18 ± 0.76),(4.25 ± 0.78 ),(3.65 ± 0.67)ml],the differences were statistically significant (all P ＜ 0.05); the differences between groups in regional ejection fractions,regional-global ejection fractions were statistically significant(F =4.56,4.88,4.28,3.15,2.93,2.88,P ＜ 0.01 or ＜ 0.05; F =5.56,5.28,4.98,5.15,3.03,2.78,P ＜ 0.01 or ＜ 0.05).Compared with 1 week before the operation, 1 month after the operation in regional ejection fractions,10 days,1 month in regionalglobal ejection fractions after the operation,4 segments of them were significantly improved(all P ＜ 0.05) and 3 months after operation,all the 6 segments had been improved significantly(all P ＜ 0.05).The maximum volume of the sum of group difference of the 6 segments and the 4 segments in the last phase of diastole was statistically significant(F =2.58,5.81,P ＜ 0.05 or ＜ 0.01 ),and the summation began to decrease 10 days after the operation.The values of 3 months after operation[ (36.27 ± 1.10),(25.35 ± 1.16)ml] were compared with that of 1 week before operation[ (44.80 ± 1.36),(31.32 ± 1.43)ml ] the difference was statistically significant (all P＜ 0.05).The maximum volume summafion comparisons of 6 segments and 4 segments in the last phase of systolic had statistical significance(F =5.77,5.57,all P ＜ 0.01 ),and 10 days after the operation,the summation began to decrease.The values of 1 month[(16.4 0 ± 0.48),(11.58 ±0.51 )ml],and 3 months after operation[ (14.65 ± 0.45),(10.26 ± 0.46)ml],were compared with those of 1 week before operation[ (26.40 ± 0.80),(18.50 ± 0.84)ml],the differences were statistically significant (all P ＜ 0.05).ConclusionsStunned myocardium can be improved through CABG in myocardium systolic,diastole function and ejection fractions of the relevant segments and all of this have proved that patients undergoing CABG revascularization can improve the heart function of the ischemic area.
