ABSTRACT
Da Chaihu decoction is a classic prescription for the treatment of cholecystitis that is widely used in clinical practice, and has a definite curative effect. However, due to its diverse components and complex functions, the traditional indexes fail to capture its overall efficacy. Therefore, this study analyzed and predicted the quality markers (Q-markers) of Da Chaihu decoction based on specific chromatogram and network pharmacology to provide a reference for the comprehensive control of the quality. The study obtained 35 potential practical components of Da Chaihu decoction through virtual screening. The specific chromatogram of 15 batches of Da Chaihu decoction was established by HPLC-DAD with neohesperidin as a reference. Compared with the chromatographic peaks and the reference substance, the chemical components were assigned to predict the nine components of albiflorin, paeoniflorin, naringin, hesperidin, neohesperidin, baicalin, wogonoside, saikosaponin b2, saikosaponin b1 as Q-markers of Da Chaihu decoction. Finally, the network of the "components-key targets-signal pathways-biological processes" was constructed by network pharmacology to explore the mechanism of Da Chaihu decoction in treating cholecystitis to clarify the accuracy of Q-markers. The results indicated that potential Q-markers could act on multiple targets to regulate inflammatory and metabolism, and then combine to treat cholecystitis. Q-markers could combine with the pharmacologic action of Da Chaihu decoction, which could elucidate the overall efficacy of Da Chaihu decoction. This study explored the Q-markers of Da Chaihu decoction combined with the specific chromatogram and network pharmacology, which provided a basis for the quality control and evaluation of Da Chaihu decoction.
ABSTRACT
To observe the clinical efficacy of modified Da Chaihu decoction in treating essential hypertension with anxiety, the randomized, controlled, clinical trial was performed in this study. One hundred and twenty-six hypertensive patients with anxiety meeting the inclusive criteria were randomized into the treatment group and the control group. All of the included patients in the above 2 groups were treated by amlodipine besylate tablets. Patients in the treatment group were given Chinese herbal medicine modified Da Chaihu decoction every day. And patients in the control group were given flupentixol and melitracen tablets. The treatment course was 4 weeks. Blood pressure, the score of traditional Chinese medicine syndrome, blood lipids, C reactive protein, the Hamilton anxiety scale score and adverse effects were observed. It has been identified that, both systolic and diastolic blood pressure were significantly reduced (P<0.05). However, no significant difference between the treatment group and the control group was identified. For traditional Chinese medicine syndrome, it was significantly improved in the treatment group (P<0.05). For blood lipids, TC, TG, HDL-C, and LDL-C were significantly improved in the treatment group (P<0.05). After treatment, only TC was significantly reduced in the treatment group when compared to the control group (P<0.05). For C reactive protein, it was significantly reduced in the treatment group after treatment (P<0.05). For anxiety, no significant difference between the treatment group and the control group on the Hamilton anxiety scale score was identified. For adverse effect, no severe adverse effect was identified in this study. The modified Da Chaihu decoction maybe effective in the treatment of essential hypertension with anxiety. In addition to a certain role in lowering blood pressure, the modified Da Chaihu decoction was also effective in improving traditional Chinese medicine syndrome and blood lipids, reducing the level of C reactive protein, relieving anxiety with little adverse effect.
ABSTRACT
[Objective] Preliminary clinical experience of Wang Zuoshun using Da Chaihu decoction contacts with other decoctions in the treatment of re-fractory hypertension in winter. [Methods] From the etiology and pathogenesis, syndrome differentiation and treatment, clinical treatment experience sum-mary of Professor Wang Zuoshun 's treatment of winter refractory hypertension academic ideas and clinical experience, also from the classical articles, the-ory of constitution etc to expound the omechanisationf the clinical experience.[Results] The etiology is phlegm, blood stasis, induced by cold pathogen, its pathogenesis are dysfunction of Shaoyang, accumulation of phlegm-heat and blood stasis, cold accumulation, according to the etiology and pathogenesis, forming a cardinal in Shaoyang, purging heat, resolving phlegm and removing blood stasis, slightly with temperature and the treatment. [Conclusions] In clinical work, Wang Zuoshun director using syndrome differentiation and treatment, researches the pathogenesis, flexibility in the use of traditional Chinese herbal soup recipe in treating winter refractory hypertension, the curative effect is remarkable, and has popularization and application value.
