ABSTRACT
By systematically sorting out the ancient medical books and modern clinical literature of Yiguanjian， the historical evolution of this formula， including its source， composition， origin， processing， dosage， preparation and usage， functions and indications， evolution of prescription meaning， is textual so as to clarify the historical evolution and clinical application of Yiguanjian. On the basis of fully considering the actual demand of development of famous classical formula preparation and the usage habit of modern clinical practice， the feasible development suggestions were put forward. Yiguanjian is composed of six herbs， which is derived from Yifang Jiedu (《医方絜度》) . It is an ancient book of traditional Chinese medicine edited by QIAN Min-jie in Qing dynasty. The original medicinal plants and medicinal parts of the formula were basically the same as those recorded in the 2020 edition of Chinese Pharmacopoeia. The raw products should be selected for decoction pieces and processed according to the methods recorded in the 2020 edition of Chinese Pharmacopoeia. The reference dose of the medicine in this formula is set out in Yifang Jiedu. According to dosage of one Qian（钱）=3.73 g， the dosages of Glehniae Radix， Ophiopogonis Radix and Angelicae Sinensis Radix were 5.60 g， the dosages of Lycii Fructus and Rehmanniae Radix were 11.19 g， the dosage of Toosendan Fructus was 7.46 g. These decoction pieces were boiled and warm decoction was taken. According to ancient medical records， the formula always has the effect of nourishing Yin and relieving Qi of liver. It is used to treat syndrome of stagnation of liver-Qi and deficiency of liver-Yin and kidney-Yin， which can be seen with pain in chest， stomach and flank， acerbity and vomiting， dry throat and mouth， red tongue， weak pulse or deficiency of string and hernia. Here， the source， processing and others of Yiguanjian were clarified， providing a literature reference for the development and application of this famous classical formula.
ABSTRACT
<p><b>OBJECTIVE</b>To study the proliferation and apoptosis in carbon tetrachloride induced rat liver fibrosis.</p><p><b>METHODS</b>Wistar rats were injected subcutaneously with 40% CCl4-olive oil twice weekly for 12 weeks. Liver tissues were obtained at the end of 4, 8, 12 and 16 weeks for histological examination, hydroxyproline (Hyp) assay and proteomic analysis. After two dimension electrophoresis (2-DE), the silver stained gels were analyzed with PDQUEST 2-DE. More than 30 differentially expressed proteins were identified by MALDI-TOF-MS.</p><p><b>RESULTS</b>The degree of collagen deposition and hydroxyproline content of the fibrotic livers increased continuously during the 12 weeks of CCl4 administration, peaked at the end of week 12 (P < 0.05) and declined significantly at week 16 (P < 0.05). Significant differences were observed in two parameters at each time point between the control and the model group. Meanwhile, dramatic change of hepatic proteome in the model group rats was also seen. Differentially expressed proteins identified by MALDI-TOF-MS were categorized as proliferation-related proteins/enzymes (proliferating cell nuclear antigen p120, p40 and cyclin F ubiquitin-conjugating enzyme 7 UBC7), and apoptosis-related proteins, mainly caspase-12 which was absent in the control rats.</p><p><b>CONCLUSION</b>Proliferation and apoptosis related proteins are expressed dynamically in different stages of rat liver fibrosis induced by CCl4.</p>
