[Show abstract][Hide abstract] ABSTRACT: Sanmiao formula (SM) is a basic prescription for the treatment of gouty and rheumatoid arthritis that has been used in China over a long period of history. However, there is no evidence associating SM with the treatment of osteoarthritis (OA). In this study, a characterization of the anti-OA effect of SM was conducted using an in vivo rat model induced by anterior cruciate ligament transection and medial meniscus resection (ACLT plus MMx), together with in vitro studies using chondrocytes for further molecular characterization. Rats subjected to ACLT plus MMx were treated with SM at doses of 0.63, 1.25 and 2.5 g/kg per day for three or six weeks. SM treatment significantly inhibited the histopathological changes of articular cartilage damage and synovial inflammation in the rats following ACLT plus MMx. SM (2.5 g/kg) clearly inhibited chondrocyte apoptosis and prevented cartilage matrix degradation, which was indicated by the increased proteoglycan and collagen content, particularly with regard to type II collagen expression in articular cartilage. Furthermore, SM (2.5 g/kg) markedly inhibited the release of interleukin (IL)-1β, tumor necrosis factor-α and nitric oxide in serum, while simultaneously increasing the levels of bone morphogenetic protein-2 and transforming growth factor-β in the circulation. Notably, SM (2.5 g/kg) clearly attenuated the OA-augmented expression of matrix metalloproteinase (MMP)-13 and augmented the OA-reduced expression of tissue inhibitor of metalloproteinase (TIMP)-1 in the knee joints. In addition, SM significantly reduced the proportion of early and late apoptotic and sub-G1 phase cells, and clearly decreased the expression of MMP-13 and increased that of TIMP-1 at the mRNA and protein levels in IL-1β-induced chondrocytes. These findings provide the first evidence that SM effectively treats OA by inhibiting chondrocyte apoptosis, cartilage matrix degradation and the inflammatory response.

[Show abstract][Hide abstract] ABSTRACT: Traditional Chinese Medicines (TCM) containing multi-interactive compounds, which have been used for treatment of perimenopause syndrome and become a new phytoestrogens resource. QiBaoMeiRan formula (QBMR) including Polygoni Multiflqri Radix, Angelicae Sinensis Radix, Achyranthis Bidentatae Radix, Cuscutae Semen, Lycii Fructus, Poria and Psoraleae Fructus has been used clinically for treating osteoporosis in postmenopausal women by virtue of its kidney-invigorating function, however, no evidence base links QBMR to estrogen replacement therapy. In this study, we undertake a characterization of estrogenic activity of QBMR using an ovariectomized (OVX) rats. OVX rats were treated with QBMR at doses of 0.875, 1.75, and 3.5 g/kg per day for 8 weeks. QBMR treatments demonstrated significant estrogenic activity, as indicated by vaginal cornification, reversal of atrophy of uterus, vagina and mammary gland, up-regulation of estrogen receptor (ER） and ER expressions in the reproductive target tissues, where ER up-regulation was stronger than that of ER. Meanwhile, treatment with QBMR significantly increased adrenal weight and serum estradiol levels and trended to decrease serum follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels in a dose dependent manner. Moreover, QBMR significantly decreased weight gain and rectal temperature increase caused by ovariectomy and the largest changes in rectal temperature were found at the lowest dose. The data suggest that QBMR's estrogenic responses show tissue variation that reflects different affinities of ERs for QBMR components. This study demonstrates QBMR activity is mediated through estrogenic components and provides an evidence base for QBMR treatment of postmenopausal symptoms.

[Show abstract][Hide abstract] ABSTRACT: To explore the rules of clinical application of Shenmai Injection (SI).
The data sets of SI were downloaded from CBM database by the method of literature retrieved from Jan. 1980 to May 2012. Rules of Chinese medical patterns, diseases, symptoms, Chinese patent medicines (CPM), and Western medicine (WM) were mined out by data slicing algorithm, and they were demonstrated in frequency tables and two-dimension based network.
Totally 3 159 literature were recruited. Results showed that SI was most frequently correlated with stasis syndrome and deficiency syndrome. Heart failure, arrhythmia, myocarditis, myocardial infarction, and shock were core diseases treated by SI. Symptoms such as angina pectoris, fatigue, chest tightness/pain were mainly relieved by SI. For CPM, SI was most commonly used with Compound Danshen Injection, Astragalus Injection, and so on. As for WM, SI was most commonly used with nitroglycerin, fructose, captopril, and so on.
The syndrome types and mining results of SI were the same with its instructions. Stasis syndrome was the potential Chinese medical pattern of SI. Heart failure, arrhythmia, and myocardial infarction were potential diseases treated by SI. For CPM, SI was most commonly used with Danshen Injection, Compound Danshen Injection, and so on. And for WM, SI was most commonly used with nitroglycerin, fructose, captopril, and so on.

[Show abstract][Hide abstract] ABSTRACT: To analysis the changes of two chemical constituents, namely 2, 3-dihydro-3, 5- dihydroxy-6-methyl-4H-pyran-4-one (DDMP) and 5-hydryoxymethyl-furfural (5-HMF) produced in Radix Polygoni Multiflori after processing, with processing time, and to determine the contents of 5-HMF in samples of Radix Polygoni Multiflori and Radix Polygoni Multiflori preparata.
An HPLC method was applied with a Zobax SB-C18 (3.9 mm x 150 mm, 5 microm) column by a elution using methanol-water (10: 90) as the mobile phase. The detection was set at UV 280 nm.
The contents of DDMP were increasing with the processing time until 24 hour, followed by a decrease until 60 hour process. The contents of 5-HMF were increasing gradually throughout the 60 hour steaming process. The contents of 5-HMF in 11 samples of Radix Polygoni Multiflori preparata were from 0.013% to 0.101%, and only one in 4 samples of Radix Polygoni Multiflori containing trace amount of 5-HMF.
The chemical components in Radix Polygoni Multiflori were changed during the processing procedures. Therefore, the processing of Radix Polygoni Multiflori should be controlled and standardized.

[Show abstract][Hide abstract] ABSTRACT: To study the new chemical constituents from Radix Polygoni Multiflori after processing.
Various kinds of chromatographic methods were used to deparate the chemical constituents from Radix Polygoni Multiflori after processing. Their structures were determined by NMR and MS spectral data.
The two new compounds were 2,3-dihydro-3,5-dihydroxy-6-meth-yl-4 (H)-pyran-4-one(I) and 5-hydruoxymethyl-furfuran(II).
It is the first time that compound I and 1I were isolated from Polygoni.

[Show abstract][Hide abstract] ABSTRACT: Different methods of processing Radix Polygoni Multiflori and the change of chemical components including emodin, physcion, 2,3,5,4'-stilbene glucoside, and tannin were investigated. The dried roots of polygoni were processed in different ways, such as, steamed with black bean sauce, steamed with water, stewed with black bean sauce, and stewed with black bean sauce at high pressure, for h and 36 h, respectively. The process stewing with black bean sauce was also investigated for 12, 24, 36 h, and 48 h, respectively. The results indicated that 2,3,5,4'-stilbene glucoside and total free anthraquinones varied in different processes. In the process of black bean sauce stewing, the content of 2,3,5,4'-stilbene glucoside decreased with processing time, reached 17% of original at 48 h. The content of tannin and combined and free anthraquinones also decreased with processing time. It was concluded, therefore, that the processing of Radix Polygoni Multiflori should be standardized to avoid significant variation of chemical contents.
