ABSTRACT
Type 2 diabetes mellitus(T2DM), a common chronic metabolic disease, is often accompanied by internal heat syndrome. Heat-clearing prescriptions are widely used to treat different heat syndromes of T2DM from the aspects of clearing stagnant heat, excess heat, damp heat, phlegm heat, and heat toxin, demonstrating remarkable effects. The mechanism of blood sugar-lowering agents has always been a hotspot of research. Recently, the basic studies of heat-clearing prescriptions from different perspectives have been increasing year by year. To clarify the mechanisms of heat-clearing prescriptions and find specific mechanisms, we systematically reviewed the basic studies of heat-clearing prescriptions commonly used for the treatment of T2DM in the past decade, intending to provide a reference for related research.

To study the differences and similarities in pharmaceutical characterization and pharmacodynamic characterization between the single decoction and merger decoction of Baihu and Guizhi. The same technology parameters were used to prepare Baihu and Guizhi single decoticon and merger decoction extracts, and then the differences and similarities in pharmaceutical characterization were analyzed based on their HPLC fingerprint, content of index components, and the extraction content. The pharmacodynamic differences and similarities were analyzed by inflammatory model and pain model. There was no significant difference in HPLC chromatographic peak, but the peak area value reflected the difference of quantity to some extent. It was found that the peak value of single Rhizoma anemarrhenae and Cassia twig decoction was less than the peak of their merger decoction, but the peak value of single honey-fried Licorice root decoction was greater than the peak of merger decoction． The contents of neomangiferin, mangiferin and timosaponin B Ⅱ among index components as well as extraction content in merger decoction were higher than those in single decoction． The contents of liquiritin and glycyrrhizic acid as well as extraction content in merger decoction were lower than those in single decoction． There was no significant difference in the content of cinnamicacid and its extraction content between merger decoction and single decoction. According to the efficacy experiment, both of them showed significant anti-inflammatory and analgesic effects. However, the merger decoction showed faster anti-inflammation effect, and longer analgesic effect. It can be concluded that the merger decoction and single decoction of Baihu and Guizhi have the same material basis, and the merger decoction is better for the dissolution of the active ingredients in this recipe, and is more beneficial to the therapeutic effect.
ABSTRACT
Qi-fen fever is a syndrome of Qi-fen syndrome in defensive qi nutrient blood syndrome differentiation. Baihu Decoction is a classic prescription of cooling Qi-fen, but when yang brightness heat at qi aspect is too exuberance to hurt human healthy qi and body fluid, Baihu with Ginseng Decoction will be used for treatment. In order to explore the mechanism of antipyretic effects of Baihu with Ginseng Decoction, this paper applied the network pharmacology method on the basis of summarizing the effects of ginseng on the natural immune system and the relationship between fever and the natural immune system. Firstly, 22 chemically active components of ginseng and their corresponding targets were screened by TCMSP database under limited conditions, and HPO database was used to search for fever-related disease targets. Secondly, the "ginseng-target-fever" network was constructed by STRING database corresponding to ginseng chemical active ingredients target and fever-related disease targets, and Cytoscape software was used to visualize the above network and obtained 18 key nodes according to the relevant characteristic parameters. Finally, The GATHER database platform was applied for the enrichment analysis of the gene function of key nodes. According to the network construction and topological calculation, it suggests that ginseng could activate the natural immune system by regulating MyD88-dependent or MyD88-independent Toll-like receptor signaling pathway to promote the antipyretic effects of Baihu Decoction.
ABSTRACT
This study was aimed to develop an HPLC method for simultaneous determination of five active components in Baihu and Guizhi decoction.Simultaneous determination of mangiferin,neomangiferin,glycyrrhizic acid,liquiritin,and cinnamic acid in Baihu and Guizhi decoction were conducted by HPLC-PDA under multiple UV wavelengths.An Waters xBridge BEH C18 Column (4.6 mm × 250 μm,5 μm) was used.The mobile phase was acetonitrile-0.01％ formic acid solution.The flow rate was 1 mL·min-1.The column temperature was kept at 24℃.The detection wavelength was set at 255 nm and 280 nm.The results showed that the linear range of mangiferin,neomangiferin,glycyrrhizic acid,liquiritin,and cinnamic acid was 66-1 976 μg (r =0.999 3),70-3487 μg (r =0.999 7),30-913 μg (r =0.999 5),35-1 734 μg (r =0.999 5),0.6-187 μg (r =0.999 8) in 70 min,respectively.The average recovery was between 95.29％ and 100.17％.It was concluded that the method was convenient,stable,reliable and accurate for simultaneous determination of the five components in Baihu and Guizhi decoction.It provided an evaluation method for the quality control of Baihu and Guizhi decoction and the research o its granules.
ABSTRACT
Objective To explore the clinical efficacy of Baihu decoction combined with insulin on type 2 diabetes with acute hyperglycemia patients.Methods A total of 86 cases of type 2 diabetes with acute hyperglycemia patients were randomly divided into experimental group (n=43) and control group (n=43).Two groups of patients underwent conventional exercise and diet adjustment intervention, control group was treated with insulin, continuous injection of 14d, experimental group was treated with Baihu decoction based on control group, 7d was taken for one courses, two course in all.The clinical symptoms of the two groups were compared, and the FPG, 2hPBG, HbAlc levels was detected in two groups pre-and post-reatment, the serum IL-6, hs-CRP, TNF-α, LP, APN, Cor were detected by enzyme linked immunosorbent assay method.Results The total effective rate was 91.7%in experimental group, higher than 76.7% in control group(P<0.05).After treatment, FPG, 2hPBG, HbAlc, IL-6, hs-CRP, TNF-αlevels in two groups were all significantly decreased (P<0.05), and those indexes in experimental group were significantly lower than those in control group (P<0.05).After treatment, APN and LP were significantly decreased, Cor was significantly increased in two groups(P<0.05), and the LP and APN in experimental group were significantly lower and Cor was significantly higher than that in control group (P<0.05).Conclusion Baihu decoction combine with insulin can significantly improve the clinical symptoms in type 2 diabetes with acute hyperglycemia patients, reduce the level of blood glucose and cytokines, and its mechanism may be relate to the increase APN level, reduce the LP and Cor levels.
ABSTRACT
According to the texts of Baihu Jia Renshen Decoction in the books of Maijing,Qianjin Yaofang,Qianjin Yifang,Taiping Shenghui Fang,Hxin Fang,and Jingui Yuhan Jing,the author drew the following conclusions:Baihu Jia Renshen Decoction in the present Shanghan Lun was very likely the written error Of Baihu Decoction,which was more close to the original meaning of Zhang Zhong-jing.From the period of Sui and Tang Dynasty,doctors had gotten new experiences in their practices.They added Ginsen into Baihu Decoction and named the new decoction"BaihU Jia Renshen Decoction",which was still in use today.Although there was not intrinsically difierence between Baihu Decoction and Baihu Jia Renshen Decoction,while the saying of"adding Renshen or not,should be decided by patient's Yuanqi"by doctor Shu Chi-yuan in Qing Dynasty had a significant impact.The erroneous views by some recent scholars can't be complied with,who advocated that the four main symptoms of Baihu Decoction syndrome should belong to syndrome of Baihu Jia Renshen Decoction according to the original texts in Shanghan Lun.
ABSTRACT
[Objective] To observe the inhibitory effect of Baihu Decoction (BD) on adverse reaction induced by photodynamic therapy (PT) in malignant tumor patients. [Methods] Fifty-six malignant tumor patients receiving PT were equally randomized into group A and group B. The two groups received routine symptomatic western medicine treatment, and anti-inflammation treatment. Group A was treated with BD additionally. [Results] Incidence of fever was 28.6% and that of pain was 85.7% in group A, and 57.1% and 100% in group B respectively (P 0.05). Duration of fever, pain and edema was respectively 2.73?0.58, 6.71?0.81 and 5.25?0.94 days in group A, and respectively 4.56?0.76, 9.12?1.14 and 8.84?1.01 days in group B (P 0.05). In group A, there were 11 patients with white blood cell (WBC) count over 10?109/L, and the average WBC count was (10.6?2.36)?109/L; there were 18 patients with WBC count over 10?109/L, and the average WBC count was (14.3?3.17)?109/L. The difference of WBC count was significant between groups A and B (P
