ABSTRACT
Zhenwutang is the classic formula of Wenyang Lishui in " <italic>Treatise on Febrile Diseases</italic>" . It consists of five kinds of medicines, namely Aconiti Lateralis Radix Praeparata, Zingiberis Rhizoma Recens, Atractylodis Macrocephalae Rhizoma, Poria, Paeoniae Radix Alba or Paeoniae Radix Rubra. It has been included in the <italic>Catalogue of Ancient Classics</italic> (<italic>The First Batch</italic>) issued by the State Administration of Traditional Chinese Medicine in 2018.There are two articles in the " <italic>Treatise on Febrile Disease</italic>s" about the syndromes of Zhenwutang. On the basis of Article 82 of the Chapter of Taiyang disease, the Taiyang disease is demonstrated by sweating, but after that the patient still suffers from fever, epigastric throb, dizziness and shiver, this shall be treated with Zhenwutang. According to Article 316 of the chapter of Shaoyin disease, Shaoyin disease lasts for two or three days, until the fourth and fifth days, and is demonstrated by abdominal pain, difficult urination, severe pain in the limbs and diarrhea, the patient have a cough, diuresis, diarrhea and vomit, this shall be treated with Zhenwutang. The original texts discuss the basic pathogenesis is edema syndrome due to Yin and Yang deficiency, with symptoms of unfavorable urination, heavy limbs or edema, pale tongue, white moss and heavy pulse as dialectical points. In terms of the compatibility of prescriptions, usage and dosage, and the interpretation of prescriptions, this paper examines Zhenwutang syndromes in " Treatise on Febrilediseases" , summarizes the material basic research of Zhenwutang, and provides the basis for the quality control of its compound pharmacodynamics. This study summarizes the progress of pharmacological research for Zhenwutang in recent years, finds that Zhenwutang has many efficacies, such as cardiotonic, diuretic, lowering lipid, anti-oxidation, improving renal function and balancing of water and liquid metabolism, lists traditional Chinese medicine(TCM) syndromes treated with Zhenwutang, such as heart palpitations, edema, cough, abdominal pain, sipping, dizziness, and Western medicine diseases, like congestive heart failure, pulmonary heart disease, bronchial asthma, chronic colitis, cirrhosis, ascites, chronic glomerulonephritis, chronic renal failure, benign prostatic hyperplasia and Meniere's syndrome, expounds the principle of Zhenwutang for " treating different diseases with the same therapy" , in order to provide useful reference for the research and development and clinical application of Zhenwutang and more classic prescriptions.
ABSTRACT
Objective: Based on the analysis of the total components of fingerprint and the determination methods of the existing components in the 2015 edition of Chinese Pharmacopoeia, the "point-line-surface" quality standard of Yangjing Zhongyu Tang was established by the "point" of each single component (morroniside, loganin, paeoniflorin, ferulic acid and verbascoside) to the "line" of multicomponent and the "face" of fingerprint of the whole component. Method: XB-C18 column (4.6 mm×250 mm, 5 μm) was used for gradient elution of 0.1% phosphoric acid aqueous solution-acetonitrile. The column temperature was 30℃, the injection volume was 10 μL, the flow rate was 1.0 mL·min-1, and the detection wavelengths were 240, 316, 230, 334 nm. The contents of these five components in Yangjing Zhongyu Tang were determined by three correction methods, external standard method and regression equation method. At the same time, the fingerprint of Yangjing Zhongyu Tang were analyzed by total component analysis and similarity evaluation. Result: With ferulic acid as reference, the relative correction factor (f) of morroniside, loganin, paeoniflorin and verbascoside were 0.392 1, 0.421 4, 0.261 7, 0.268 6 by multi-point correction method, and their f (slope correction method) were 0.385 4, 0.419 4, 0.255 9, 0.274 0, respectively. Twenty characteristic peaks of fingerprint were analyzed and the similarity was ≥ 0.999.There was no significant difference in the contents of these five components from Yangjing Zhongyu Tang determined by the quantitative assay of multi-components by single-marker (QAMS) correction method, the external standard method and the regression equation method. Conclusion: The comprehensive quality standard established by the total component analysis of fingerprint combined with various determination methods of existing components in the 2015 edition of Chinese Pharmacopoeia has been validated in famous classical formula of Yangjing Zhongyu Tang, which can provide ideas and methods for the quality control with quantitative determination and fingerprint of other famous classical formulas.
ABSTRACT
Yangjing Zhongyu Tang, from FU Qing-zhu Nvke, is a famous classical formula of clinical value for treating blood deficiency syndrome of female infertility in the Qing dynasty. The prescription seems plain, but it is rigorous and effective with high research value. In this paper, the ancient books and modern documents of Yangjing Zhongyu Tang were analyzed from the aspects of traceability of Chinese materia medica in the formula, pharmacological research, clinical research, etc. It could be concluded that the pharmacological studies of this formula were mostly to investigate the mechanism and efficacy of its treatment for infertility, but there was a lack of comprehensive interpretation of the structure, function and principle of pharmacodynamic substance in this formula. In this paper, combined with the contents of supramolecular imprinting template and network pharmacology, the new direction of pharmacological research of Chinese medicine compound was put forward. Quality control of Yangjing Zhongyu Tang mostly based on small molecule compounds, so it was suggested to break the inherent thinking, and increase the detection of macromolecule compounds and supramolecular of Chinese materia medica. The druggability of this formula involved in the preliminary study of decoctions, plasters and granules. Considering the quality stability of Chinese materia medica in the formula and the scientificity of druggability of this formula, the compatibility principle of traditional Chinese medicine (TCM) and modern supramolecular chemistry theory could be combined to study the change law of druggability of TCM before and after compatibility, so as to provide new reference materials for the follow-up clinical application and development of Yangjing Zhongyu Tang.
ABSTRACT
Objective To optimize the extraction method of Coptidis Rhizoma protein; To compare and analyze the differences of protein in different parts of wild and cultivated Coptidis Rhizoma. Methods SDS-PAGE gel electrophoresis and Coomassie brilliant blue method were used to compare the differences of the protein of Coptis chinensis from the 3 extraction methods (water extraction, Tris-HCl and ammonium sulfate precipitation), and the protein in different parts of the wild and cultivated Coptis chinensis, and analyzed and evaluated the differences. Results The optimum extraction method of Coptis chinensis protein is Tris-HCl method, and the protein content of Rhizoma Coptidis is the highest, and the content of protein is the highest in every gram of medicinal material. The differences among different parts of wild and cultivated Coptidis Rhizoma were obvious, and the ranks for protein abundance and protein content per gram were: rhizome of cultivated Coptis chinensis＞ rhizome of wild Coptis chinensis＞ stem and leaf of cultivated Coptis chinensis＞ stem and leaf of wild Rhizoma Coptidis＞ fibrous roots of cultivated Coptidis Rhizoma. Cluster analysis showed that the correlation between protein of wild and cultivated rhizome of Coptidis Rhizoma was obvious. Conclusion The optimum Tris-HCl method can extract the protein from Coptidis Rhizoma, and the protein content of roots of Coptidis Rhizoma is significantly higher than other parts.
ABSTRACT
The molecular connectivity index was adopted to explore the characteristics of supramolecular imprinting template of herbs distributed to liver meridian, in order to provide scientific basis for traditional Chinese medicines(TCMs) distributed to liver meridian. In this paper, with "12th five-year plan" national planning textbooks Science of Traditional Chinese Medicine and Chemistry of Traditional Chinese Medicine as the blueprint, literatures and TCMSP sub-databases in TCM pharmacology of northwest science and technology university of agriculture and forestry were retrieved to collect and summarize active constituents of TCM distributed to liver meridian, and calculate the molecular connectivity index. The average molecular connectivity index of ingredients distributed to liver meridian was 9.47, which was close to flavonoid glycosides' (9.17±2.11) and terpenes (9.30±3.62). Therefore, it is inferred that template molecule of liver meridian is similar to physicochemical property of flavonoid glycosides and terpenes, which could be best matched with imprinting template of liver meridian.
ABSTRACT
We investigated the causative agents of hand, foot and mouth disease (HFMD) in children in Beijing epidemic from April to June of 2007. Totally, 82 specimens (including throat swabs, rectal swabs and vesicular swabs) were collected from 51 patients with HFMD. All patients had typical skin lesions, but no neurological manifestations. These clinical specimens were directly tested by RT-PCR assay with three primer sets: universal enterovirus, CA16-specific and EV71-specific primers. Enterovirus, CA16 and EV71 were identified depending on the size of PCR products. The percentage of the specimens identified as positive for enterovirus was 70.6%. Of the 51 cases, 25 were positive for CA16, 4 were positive for EV71, and 7 were enterovirus positive of non-CA16 or EV71. The ratio among them was about 6:1:2. EV71 strains belonged to genotype C4 after sequencing and phylogenetic analysis.
