Evaluation of Compatibility Proportion and Antidepressant Mechanism of Bupleuri Radix-Scutellariae Radix Based on Uniform Design / 中国实验方剂学杂志

Objective:To optimize proportion of couplet medicine of Bupleuri Radix and Scutellariae Radix in the treatment of anti-depression, and to explore the possible antidepressant mechanism of this couplet medicine. Method:The dosages of Bupleuri Radix and Scutellariae Radix in the 2015 edition of Chinese Pharmacopoeia were taken.According to U7(72) uniform design table, Bupleuri Radix and Scutellariae Radix were carried out into 7 groups.The chronic unpredictable mild depression model mice were induced by intragastric administration of decoction of this couplet medicine and the antidepressant effect was observed by the behavior tests, which included sucrose preference test, tail suspension test, forced swimming test and open field test(crossing scores).The regression equations were established by selecting the effective indexes.The experiments of retest were taken to check the results and the possible antidepressant mechanism was primarily investigated by measuring the phosphorylation level of cyclic adenosine monophosphate(cAMP)-response element binding protein(CREB) and expression of brain-derived neurotrophic factor(BDNF). Result:Compared with the blank group, sucrose preference rate of the model group was significantly decreased(PPPPPPPPPPPPPPConclusion:Compatibility of Bupleuri Radix and Scutellariae Radix can ameliorate depressive-like behavior of model mice, and the best antidepressant compatibility proportion of Bupleuri Radix and Scutellariae Radix is 1:1, the optimal amounts of them are about 5 g.The antidepressant effect may relate to promoting phosphorylation level of CREB and the expression of BDNF in the hippocampus.

The effective parts of liangxue tongyu prescription on cooling-blood and activating-blood and analysis of chemical constituents by HPLC-MS and GC-MS / 药学学报

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

Experiences of Professor Zhou Zhong-ying in diagnosing and treating rheumatoid arthritis by data mining / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To summarize Professor ZHOU Zhong-ying's academic ideas and clinical experiences in diagnosing and treating rheumatoid arthritis (RA).</p><p><b>METHODS</b>Totally 153 clinical case reports were recruited. Data mining techniques like frequencies, factor analysis, and association analysis were used in order to find out laws of syndrome, pathogenesis, treatment methods, formulae and medication.</p><p><b>RESULTS</b>By statistical analyses, we found 14 main symptoms, 76 commonly used clinical drugs, 8 core prescriptions for RA, and the correlation between main pathogeneses and related drugs.</p><p><b>CONCLUSION</b>Results analyzed and summarized from mining his experiences in RA treatment were in line with clinical practice.</p>

Randomized and controlled clinical study of modified prescriptions of Simiao Pill in the treatment of acute gouty arthritis / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the compatibility of a modified prescription of Simiao Pill in the treatment of acute gouty arthritis and to verify the clinical efficacy and safety of the drug through a clinical trial.</p><p><b>METHODS</b>A randomized and controlled clinical trial was designed based on clinical epidemiological principles. A total of 107 patients with acute gouty arthritis were enrolled and randomly assigned to four groups. The first group (Group I) included 27 patients taking gout prescription I; the second group (Group II) included 27 patients taking gout prescription II; the third group (Group III) included 28 patients taking gout prescription III; and the fourth group (control group) included 25 patients taking indomethacin and Benzobromarone as a control group. The duration of the treatment in all 4 groups was two weeks. After the treatment, the index of blood uric acid, blood leukocyte count, score of clinical symptoms, etc. were observed and measured.</p><p><b>RESULTS</b>The total clinical effective rate of the three different modified prescriptions of the Simiao Pill was above 96%, significantly superior to that of the control group (68%, P<0.05). In terms of the improvement of main symptoms, the scores of four symptoms in all TCM treatment and control groups decreased after treatment, with statistically significant differences (P<0.05). Moreover, the scores markedly fell more so in the three Chinese herb groups than in the control group, and especially in Group III (P<0.05). There was a statistically significant difference in blood uric acid values before and after the treatment in the same group but no significant inter-group difference was seen.</p><p><b>CONCLUSION</b>The modified prescriptions, based on the clinical research, clinical experience and traditional Chinese medicine theory, did show a better effect than Western medicine in this clinical study. Moreover, the prescriptions were precise, with the herbs inexpensive and readily available. The patients had good compliance with less adverse reactions noted. The modified prescription has a favorable prospect for future development and is worthy of further blind trials with larger samples.</p>
