Xuanfu Daizhe Decoction, first seen in Zhang Zhongjing's Treatise on Cold Damage Diseases, was composed of seven medicinal materials: Inulae Flos, Glycyrrhizae Radix, Ginseng Radix, Zingiberis Rhizoma Recens, Haematitum, Pinelliae Rhizoma and Jujubae Fructus. It was used to treat gastric fullness and hardness and belching due to the wrong treatment of typhoid fever and sweating. With detailed records and description in ancient medical books, Xuanfu Daizhe Decoction was widely adopted in clinical practice by physicians of later generations, which expanded its main therapeutic functions. By comprehensive collation of ancient and modern literature on Xuanfu Daizhe Decoction, this paper systematically explored the historical evolution of the prescription from the source, composition, dosage, processing, clinical application, function interpretation and decocting method. It was found that the composition and processing method of the prescription in the past dynasties were relatively consistent, and there was a gradual decrease in dosage in clinical application. In ancient times, Xuanfu Daizhe Decoction was mainly used to treat nausea, vomiting, hiccups, constipation, etc., while modern clinicians mainly used it for digestive diseases such as reflux esophagitis and gastritis. Through the analysis and textual research, the composition, dosage, processing, function evolution and decocting method of this prescription were determined, which provided reference for the research and development of compound preparations of Xuanfu Daizhe Decoction.

The ethyl acetate fraction of ethanol extract of Eucommiae Cortex can effectively inhibit joint inflammation and bone destruction in rats with collagen-induced arthritis(CIA) and has a potential therapeutic effect on rheumatoid arthritis. The triterpenoid(EU-Tid) and iridoid(EU-Idd) of Eucommiae Cortex are derivatives isolated from the ethyl acetate fraction of the ethanol extract of Eucommiae Cortex, and it is not clear whether they have inhibitory effects on joint inflammation and bone erosion in CIA rats. Therefore, based on the CIA model, the effects of EU-Tid, EU-Idd, and their combination(EU-TP) on arthritis in rats were observed, and the material basis of Eucommiae Cortex against arthritis was further clarified. The samples were collected two and four weeks after administration to observe the pathological changes in different stages of arthritis in CIA rats. For the rats in the model control group, with the prolongation of the disease course, the paw volume and arthritis score increased and histopathological lesions aggravated. Compared with the model control group, the drug administration groups showed reduced paw volumes and arthritis scores, and improved joint lesions and cartilage destruction. Additionally, the mRNA expression levels of tumor necrosis factor-α(TNF-α), interleukin-17(IL-17), and interleukin-23(IL-23) in the spleen were down-regulated in the drug administration groups. EU-TP and EU-Tid at concentrations of 160 and 320 μg·mL~(-1) could significantly inhibit the proliferation of human fibroblast-like synoviocytes-RA(HFLS-RA) and nitric oxide(NO) release in the supernatant of RAW264.7 cells induced by lipopolysaccharide(LPS) at the concentration range of 10-80 μg·mL~(-1) in vitro. EU-Idd had no effect on the proliferation of HFLS-RA but could reduce the NO release at concentrations of 40 and 80 μg·mL~(-1). The results indicated that the terpenoids of Eucommiae Cortex had great potential in the treatment of rheumatoid arthritis.

OBJECTIVE: To investigate the effects of astragaloside Ⅳ (AS-Ⅳ) on microglia/macrophage M1/M2 polarization and inflammatory response after cerebral ischemia in rats. METHODS: Forty eight male SD rats were randomly divided into sham operation control group, model control group and AS-Ⅳ group with 16 rats in each. Focal cerebral ischemia model was induced by occlusion of the right middle cerebral artery (MCAO) using the intraluminal filament. After ischemia induced, the rats in AS-Ⅳ group were intraperitoneally injected with 40 mg/kg AS-Ⅳ once a day for 3 days. The neurological functions were evaluated by the modified neurological severity score (mNSS) and the corner test on d1 and d3 after modelling. The infarct volume was measured by 2, 3, 5-triphenyl tetrazolium chloride (TTC) staining on d3 after ischemia. The expression of M1 microglia/macrophage markers CD86, inducible nitric oxide synthase (iNOS) and pro-inflammatory factors TNF-α, IL-1β, IL-6, M2 microglia/macrophages markers CD206, arginase-1 (Arg-1), chitinase-like protein (YM1/2) and anti-inflammatory factors interleukin-10 (IL-10) and transforming growth factor beta (TGF-β) was detected by real-time RT-PCR. The expression of CD16/32/Iba1 and CD206/Iba1 was determined by double labeling immunefluorescence method in the peripheral area of cerebral ischemia. RESULTS: Compared with model control group, AS-Ⅳ treatment improved neurological function recovery and reduced infarct volume after ischemia ( CONCLUSIONS The findings suggest that AS-Ⅳ ameliorates brain injury after cerebral ischemia in rats, which may be related to inhibiting inflammation through promoting the polarization of the microglia/macrophage from M1 to M2 phenotype in the ischemic brain.

OBJECTIVE: To examine the effects of ursolic acid (UA) on mitigating retinoic acid (RA)-induced osteoporosis in rats. METHODS: Fifty female Sprague-Dawley rats were randomly divided into the control group (n=10) and the osteoporosis group (n=40). The 40 osteoporosis rats were induced by 75 mg/(kg•d) RA once daily for 2 weeks, and then were randomly assigned to vehicle control (model), low-, middle-, and high-dose UA [(UA-L, UA-M, UA-H; 30, 60, 120 mg/(kg•d), respectively] groups (10 rats each). UA were administered once daily to the rats from the 3rd weeks for up to 4 weeks by gavage. Bone turnover markers [serum alkaline phosphatase (ALP), osteocalcin (OCN), urine deoxypyridinoline (DPD)] and other parameters, including serum calcium (S-Ca), serum phosphorus (S-P), urine calcium (U-Ca), urine phosphorus (U-P), and bone mineral density (BMD) of the femur, 4th lumbar vertebra and tibia, bone biomechanical properties and trabecular microarchitecture, were measured. RESULTS: The osteoporosis in rats was successfully induced by RA. Compared with the model group, UA-M and UA-H significantly reversed the RA-induced changes in S-P, U-Ca, U-P, ALP, OCN and urine DPD ratio and markedly enhanced the BMD of right femur, 4th lumbar vertebra and tibia (Plt;0.05 or Plt;0.01). Further, biomechanical test and microcomputed tomography evaluation also showed that UA-H drastically improved biomechanical properties and trabecular microarchitecture (Plt;0.05 or Plt;0.01). CONCLUSION UA could promote bone formation, increase osteoblastic activity and reduce osteoclastic activity in rats, indicating that UA might be a potential therapeutic of RA-induced acute osteoporosis.

Antrodia camphorata, a well-known and highly valued edible medicinal mushroom with intriguing activities like liver protection, has been traditionally used for the treatment of alcoholic liver disease. A. camphorata shows highly medicinal and commercial values with the demand far exceeds the available supply. Thus, the petri-dish cultured A. camphorata (PDCA) is expected to develope as a substitute. In this paper, nineteen triterpenes were isolated from PDCA, and thirteen of them were the unique anthroic acids in A. camphorata, including the main content antcin K, which suggested that PDCA produced a large array of the same anthroic acids as the wild one. Furthermore, no obvious acute toxicity was found suggesting the edible safety of PDCA. In mice alcohol-induced liver injury model, triglyceride (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and malondialdehyde (MDA) had been reduced by the PDCA powder as well as the main content antcin K, which indicated that the PDCA could protect alcoholic liver injury in mice model and antcin K could be the effective component responsible for the hepatoprotective activities of PDCA against alcoholic liver diseases.

Cardiovascular disease (CVD) is the most common cause of death in patients with non-alcoholic fatty liver disease (NAFLD). New therapeutic strategies which have the potential for slowing down the evolution of NAFLD and reducing CVD-related mortality are urgently needed. Statins are well recognized in the treatment of dyslipidemia, but their use in the treatment of NAFLD is limited due to the safety concerns. Ilexgenin A (IA) is one of the main bioactive compounds in 'Shan-lv-cha', an herbal tea commonly used in China. In the present study, we investigated the possible synergistic therapeutic effects of IA and simvastatin (SV) on NAFLD. IA or SV showed beneficial effects on the rats with NAFLD by lowering the liver weight, liver index and plasma levels of alanine aminotransferase and aspartate aminotransferase, regulating abnormal metabolism of lipids and ameliorating steatosis in liver. IA significantly enhanced the hypolipidemic and anti-inflammation effects of SV. Furthermore, a sensitive, accurate, convenient and reproducible LC-MS method was developed to investigate the effects of IA on the pharmacokinetics of SV. No significant changes were observed in pharmacokinetic parameters of SV and simvastatin hydroxy acid in the IA plus SV co-treated group in comparison with those in the group treated with SV alone. The mRNA levels and activity of CYP3A1 were not altered by IA. In conclusion, the results obtained from the present study should be helpful for further clinical application of SV and IA alone or in combination.

Fibroblast-like synoviocytes (FLS) play a pivotal role in Rheumatoid arthritis (RA) pathogenesis through aggressive migration and invasion. Madecassoside (Madec), a triterpenoid saponin present in Centella asiatica herbs, has a potent anti-inflammatory effect. In the present study, Madec exerted an obvious therapeutic effect in reversing the histological lesions in adjuvant-induced arthritis (AIA) rats. To recognize the anti-rheumatoid potentials of Madec, we further investigated whether Madec interfered with FLS invasion and metalloproteinase (MMP) expression. In cultures of primary FLS isolated from the AIA rats, Madec (10 and 30 μmol·L) was proven to considerably inhibit migration and invasion of FLS induced by interleukin 1β (IL-1β), but exhibiting no obvious effect on cell proliferation. Madec repressed IL-1β-triggered FLS invasion by prohibiting the expression of MMP-13. Additionally, Madec suppressed MMP-13 transcription via inhibiting the MMP-13 promoter-binding activity of NF-κB. Our results further showed that Madec down-regulated the translocation and phosphorylation of NF-κB as demonstrated by Western blotting and immunofluorescence assays. In conclusion, our results suggest that Madec exerts anti-RA activity via inhibiting the NF-κB/MMP-13 pathway.

Platycodin D (PD), a triterpenoid saponin isolated from Platycodonis Radix, is a famous Chinese herbal medicine that has been shown to have anti-proliferative effects in several cancer cell lines. The aim of this study was to determine the changes in cellular proteins after the treatment of hepatocellular carcinoma HepG2 cells with PD using proteomics approaches. The cell viability was determined using the MTT assay. The proteome was analyzed by two-dimensional difference gel electrophoresis and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Western blot analysis was used to confirm the expression of changed proteins. Our results showed that PD inhibited the proliferation of HepG2 cells in concentration- and time-dependent manners. Sixteen proteins were identified to be up-regulated in PD-treated HepG2 cells, including ATP5H, OXCT1, KRT9, CCDC40, ERP29, RCN1, ZNF175, HNRNPH1, HSP27, PA2G4, PHB, BANF1, TPM3, ECH1, LGALS1, and MYL6. Three proteins (i.e., RPS12, EMG1, and KRT1) decreased in HepG2 cells after treatment with PD. The changes in HSP27 and PHB were further confirmed by Western blotting. In conclusion, our results shed new lights on the mechanisms of action for the anti-cancer activity of PD.

The Goto-Kakizaki (GK) rat is a spontaneous type 2 diabetic animal model, which is characterized by a progressive loss of beta islet cells with fibrosis. In the present study, the hypoglycemic effect of asiatic acid (AA) in GK rats was examined. GK rats receiving AA at a daily dose of 25 mg·kg(-1) for four weeks showed a significant reduction in blood glucose levels. Age-matched normal Wistar rats were given 0.5% sodium carboxymethyl cellulose (CMC-Na) solution for the same periods and used as control. Compared to the normal Wistar rats, GK rats treated with AA showed improvement in insulin resistance partially through decreasing glucose level (P < 0.01) and insulin level (P < 0.05). Furthermore, the results of immunohistochemistry indicate that AA treatment reduced islet fibrosis in GK rats. Fibronectin, a key protein related to islet fibrosis, was over-expressed in GK rats, which was reversed significantly by AA treatment (P < 0.05). These findings suggest that AA has a beneficial effect on lowering blood glucose levels in GK rats and improves fibrosis of islets in diabetes, which may play a role in the prevention of islets dysfunction.
