Abstract
Three new hasubanan-type alkaloids, stephalonine Q (1), stephalonine R (2) and stephalonine S (3), together with four known alkaloids, isolonganone (4), eletefine (5), aurantiamide (6), N-cinnamoyltyramine (7), were isolated from the whole plant of Stephania longa. Their structures were identified by NMR, HR-ESI-MS, CD methods and x-ray crystallography, as well as by comparison with the literature data. All isolated compounds were evaluated for their antimicrobial activities against five bacteria in vitro. Compound 5 displayed inhibitory activity against only S. aureus, with an MIC value of 50 μg/mL.

Chinese Herbal Medicines for Rheumatoid Arthritis: Text-Mining the Classical Literature for Potentially Effective Natural Products. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:7531967. [PMID: 32419824 PMCID: PMC7206865 DOI: 10.1155/2020/7531967] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Accepted: 03/09/2020] [Indexed: 12/12/2022]
Abstract
Background Rheumatoid arthritis (RA) is an autoimmune disease characterized by multijoint swelling, pain, and destruction of the synovial joints. Treatments are available but new therapies are still required. One source of new therapies is natural products, including herbs used in traditional medicines. In China and neighbouring countries, natural products have been used throughout recorded history and are still in use for RA and its symptoms. This study used text-mining of a database of classical Chinese medical books to identify candidates for future clinical and experimental investigations of therapeutics for RA. Methods The database Encyclopaedia of Traditional Chinese Medicine (Zhong Hua Yi Dian) includes the full texts of over 1,150 classical books. Eight traditional terms were searched. All citations were assessed for relevance to RA. Results and Conclusions. After removal of duplications, 3,174 citations were considered. After applying the exclusion and inclusion criteria, 548 citations of traditional formulas were included. These derived from 138 books written from 206 CE to 1948. These formulas included 5,018 ingredients (mean, 9 ingredients/formula) comprising 243 different natural products. When these text-mining results were compared to the 18 formulas recommended in a modern Chinese Medicine clinical practice guideline, 44% of the herbal formulas were the same. This suggests considerable continuity in the clinical application of these herbs between classical and modern Chinese medicine practice. Of the 15 herbs most frequently used as ingredients of the classical formulas, all have received research attention, and all have been reported to have anti-inflammatory effects. Two of these 15 herbs have already been developed into new anti-RA therapeutics—sinomenine from Sinomenium acutum (Thunb.) Rehd. & Wils and total glucosides of peony from Paeonia lactiflora Pall. Nevertheless, there remains considerable scope for further research. This text-mining approach was effective in identifying multiple natural product candidates for future research.

Abstract
Inflammatory bowel disease (IBD) is a chronic and life-long disease characterized by gastrointestinal tract inflammation. It is caused by the interplay of the host's genetic predisposition and immune responses, and various environmental factors. Despite many treatment options, there is no cure for IBD. The increasing incidence and prevalence of IBD and lack of effective long-term treatment options have resulted in a substantial economic burden to the healthcare system worldwide. Biologics targeting inflammatory cytokines initiated a shift from symptomatic control towards objective treatment goals such as mucosal healing. There are seven monoclonal antibody therapies excluding their biosimilars approved by the US Food and Drug Administration for induction and maintenance of clinical remission in IBD. Adverse side effects associated with almost all currently available drugs, especially biologics, is the main challenge in IBD management. Natural products have significant potential as therapeutic agents with an increasing role in health care. Given that natural products display great structural diversity and are relatively easy to modify chemically, they represent ideal scaffolds upon which to generate novel therapeutics. This review focuses on the pathology, currently available treatment options for IBD and associated challenges, and the roles played by natural products in health care. It discusses these natural products within the current biodiscovery research agenda, including the applications of drug discovery techniques and the search for next-generation drugs to treat a plethora of inflammatory diseases, with a major focus on IBD.

Abstract
We performed a retrospective cohort study to investigate the association between the risk of ischemic stroke (IS) and the use of Chinese herbal products (CHP) in combination with western medicine (WM) among patients with rheumatoid arthritis (RA). The data were sourced from the registry for beneficiaries, inpatient and ambulatory care claims, and Registry for Catastrophic Illness from the National Health Insurance Research Database (NHIRD) in Taiwan between 1997 and 2011. Patients, who were newly diagnosed with RA between 1997 and 2010, were classified as the CHP group or non-CHP group depending on the presence of absence the adjunctive use of CHP following a diagnosis of RA. A total of 4,148 RA patients were in both the CHP and non-CHP groups after 1:1 matching. Patients in the CHP group had a significantly lower risk of IS compared to patients in the non-CHP group (adjusted hazard ratio [aHR], 0.67; 95% confidence interval [CI], 0.52-0.86). In the CHP group, patients who used CHP for more than 30 days had a lower risk of IS than their counterparts (aHR: 0.61, 95% CI: 0.40-0.91). Gui-Zhi-Shao-Yao-Zhi-Mu-Tang, Shu-Jin-Huo-Xie-Tang, and Du-Huo-Ji-Sheng-Tang might be associated with a lower risk of IS. Finally, the use of CHP in combination with WM was associated with a decreased risk of IS in patients with RA, especially among those who had used CHP for more than 30 days. A further randomized control trial is required to clarify the casual relationship between these results.

Abstract
ABSTRACT Stephania tetrandra S. Moore (S. tetrandra) is distributed widely in tropical and subtropical regions of Asia and Africa. The root of this plant is known in Chinese as "Fen Fang Ji". It is commonly used in traditional Chinese medicine to treat arthralgia caused by rheumatism, wet beriberi, dysuria, eczema and inflamed sores. Although promising reports have been published on the various chemical constituents and activities of S. tetrandra, no review comprehensively summarizes its traditional uses, phytochemistry, pharmacology and toxicology. Therefore, the review aims to provide a critical and comprehensive evaluation of the traditional use, phytochemistry, pharmacological properties, pharmacokinetics and toxicology of S. tetrandra in China, and meaningful guidelines for future investigations.

Abstract
Silicosis is an inflammatory and fibrotic lung disease caused by inhalation of silica. Th17 cells play a key role in causing silica-induced lung inflammation and fibrosis. Baicalin, a compound isolated from the Chinese herb Huangqin, could suppress the differentiation of Th17 cells and alleviate inflammation. However, there are very few reports of the immunoregulatory mechanisms of baicalin in experimental silica-induced lung inflammation and fibrosis. In our study, mice were exposed to silica by intratracheal instillation, and in this way we established an experimental silicosis model. To elucidate the effects and mechanisms of baicalin in silica-induced inflammation and fibrosis, we used baicalin to treat the developed mouse model of silicosis. Treatment with baicalin attenuated the accumulation of inflammatory cells and led to milder pathological inflammatory and fibrotic changes in lung tissues. Baicalin affected the immunological balance between Th17 and Treg responses. Therefore, baicalin caused a decrease in Th17 cells by stimulating Treg cells and by inhibiting IL-6 and IL-23. We further demonstrated that silica-induced Th1 and Th2 immune responses were both inhibited by increased Treg activation, which was promoted by baicalin. Our findings confirmed the potential functions of baicalin in inhibiting the Th17 response and reducing silica-induced inflammation and fibrosis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Large-scale study of traditional Chinese medicine (TCM) usage among patients with rheumatoid arthritis (RA) is lacking. The aim of this study is to evaluate the TCM usage among RA patients in Taiwan. MATERIALS AND METHODS We examined the "registry for catastrophic illness patient dataset" of the National Health Insurance Research Database (NHIRD; n=23 million people) in Taiwan. Patients (n=25,263) newly diagnosed as RA in 2001-2009 were included and then followed-up until the end of 2011. Based on the medical utilization, they were further categorized into TCM users (n= 6891; 27.3%) and non-TCM users (n=18,372; 72.7%). The demographic data and core prescription patterns of the TCM users were analyzed. RESULTS Compared to non-TCM user, TCM users were younger (mean age: 49.6 versus 54.0 years), had a higher female/male ratio (82.7%/17.3% versus 74.1%/25.9%), resided in more urbanized area. Herbal remedies were the most commonly used therapeutic approach (76.4%), followed by combining acupuncture (21.1%). The frequency of outpatient visits in TCM users was higher across all disease categories except circulatory system. The most commonly prescribed formula and herb was Shang-Jong-Shiah-Tong-Yong-Tong-Feng-Wan and Rhizoma Corydalis, respectively. The analysis of core pattern revealed that Dang-Gui-Nian-Tong-Tang, Shu-Jing-Huo-Xie-Tang, Gui-Zhi-Shao-Yao-Zhi-Mu-Tang, Myrrha and Olibanum, were among the most frequently used combinations. RA patients who had anxiety and depression, allergic rhinitis, osteoporosis, menstrual disorder, and menopausal syndrome were prone to have more TCM visits compared to non-TCM users. CONCLUSIONS Our population-based study revealed the high prevalence and specific usage patterns of TCM in the RA patients in Taiwan. The information could be used for further pharmacological investigation and clinical trials.

Abstract
BACKGROUND Fang-Ji-Huang-Qi-Tang (abbreviated as FJHQT), composed by six medicinal herbs including Radix Stephania Tetrandra, Radix Astragali, Rhizoma Atractylodis Macrocephalae, Radix Glycyrrhizae, Rhizoma Zingiberis and Fructus Ziziphi Jujubae, is a frequently Chinese prescription for treating painful and inflammatory disorders such as rheumatoid arthritis. When Radix Stephania Tetrandra was misused with Aristolochia species, acute or chronic nephropathy caused by aristolochic acid was happened. Thus, the present study was aimed to identify Radix Stephania Tetrandra and performed the pharmacological and toxicological evaluation of FJHQT extract in rodents. METHODS Radix Stephania Tetrandra was identified by macroscopic and microscopic observation, and the content of tetrandrine in FJHQT extract was measured by high performance liquid chromatography. Then, the pharmacological activities of FJHQT extract with respect to clinical use was investigated with acetic acid-induced writhing response, formalin-induced licking response and carrageenan-induced paw edema. Finally, we evaluated the subacute toxicology of FJHQT extract after 28-day repeated oral administration in rats. RESULTS Radix Stephania Tetrandra was correctly used in FJHQT extract, and the content of tetrandrine in FJHQT extract was 2.5 mg/g. FJHQT extract produced a pronounced and dose-dependent antinociceptive and anti-inflammatory effects in three above models. FJHQT extract after 28-day repeated administration did not caused any hematological, biochemical and histological change in rats. CONCLUSIONS We suggest that FJHQT extract is a high safety index Chinese medicine for antinociceptive and anti-inflammatory application when Radix Stephania Tetrandra was correctly used in FJHQT. Its antinociceptive and anti-inflammatory mechanism might be related to peripheral nociceptive pathway such as prostaglandins.

Abstract
Paclitaxel (Ptx), one of the most widely used anticancer agents, has demonstrated extraordinary activities against a variety of solid tumors. However, the therapeutic response of Ptx is often associated with severe side effects caused by its nonspecific cytotoxic effects and special solvents (Cremophor EL(®)). The current study reports the stable controlled release of Ptx/tetrandrine (Tet)-coloaded nanoparticles by amphilic methoxy poly(ethylene glycol)-poly(caprolactone) block copolymers. There were three significant findings. Firstly, Tet could effectively stabilize Ptx-loaded nanoparticles with the coencapsulation of Tet and Ptx. The influence of different Ptx/Tet feeding ratios on the size and loading efficiency of the nanoparticles was also explored. Secondly, the encapsulation of Tet and Ptx into nanoparticles retains the synergistic anticancer efficiency of Tet and Ptx against mice hepatoma H22 cells. Thirdly, in the in vivo evaluation, intratumoral administration was adopted to increase the site-specific delivery. Ptx/Tet nanoparticles, when delivered intratumorally, exhibited significantly improved antitumor efficacy; moreover, they substantially increased the overall survival in an established H22-transplanted mice model. Further investigation into the anticancer mechanisms of this nanodelivery system is under active consideration as a part of this ongoing research. The results suggest that Ptx/Tet-coloaded nanoparticles could be a potential useful chemotherapeutic formulation for liver cancer therapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Stage 3 is the key phase of chronic kidney disease. Traditional Chinese medicine (TCM) has been used for the treatment of chronic kidney disease. But a large sample trial is desirable. MATERIALS AND METHODS A total of 578 Chinese patients with primary glomerulonephritis in CKD stage 3 were randomly assigned to three groups: patients received TCM (TCM group), benazepril (Ben group), TCM combined with benazepril (TCM+Ben group). Patients were followed up for 24 weeks. The primary endpoint was the time to the composite of 50% increased of serum creatinine, end stage renal disease or death. RESULTS eGFR in the TCM and the TCM+Ben group were improved (week 24 vs. baseline, P<0.05) while eGFR in the Ben group was decreased (week 24 vs. baseline, P>0.05). 24h urinary protein excretion (UP) and urinary albumin/creatinine (UAlb/Cr) were decreased in the TCM+Ben (week 24 vs. baseline, P<0.05) and the Ben group (week 24 vs. baseline, P>0.05). UP and UAlb/Cr were increased in the TCM group to week 12, then were stable (week 24 vs. baseline, P<0.05). The hemoglobin in the TCM group was also improved (week 24 vs. baseline, P<0.05). The accumulative survival rate in the TCM+Ben group was higher than that in the TCM group and the Ben group (P=0.044). Side effects in the TCM group were the lowest in these groups (P<0.05). The patients with dry cough in the TCM+Ben group and the Ben group were increased as compared with the TCM group (P<0.05). Hyperkalemia happened less frequently in the TCM group as compared with the other two groups (P=0.052). CONCLUSIONS For the patients with CKD stage 3, TCM can improve eGFR and hemoglobin with lower side effects. Benazepril significantly decreased the proteinuria. Chinese medicine integrated with benazepril can ameliorate renal function and decrease proteinuria synergistically.

Abstract
The plants of the genus Stephania (Menispermaceae) are widely distributed, and have long been used in folk medicine for the treatment of various ailments such as asthma, tuberculosis, dysentery, hyperglycemia, malaria, cancer and fever. Over 150 alkaloids together with flavonoids, lignans, steroids, terpenoids and coumarins have been identified in the genus, and many of these have been evaluated for biological activity. This review presents comprehensive information on the chemistry and pharmacology of the genus together with the traditional uses of many of its plants. In addition, this review discusses the structure-activity relationship of different compounds as well as recent developments and the scope for future research in this aspect.

Abstract
We examined the antifibrotic effect of a methanol extract from Stephania tetrandra (ST) on experimental liver fibrosis. Liver fibrosis was induced by bile duct ligation and scission (BDL/S) in rats. In BDL/S rats, activity levels of aspartate transaminase (AST), alanine transaminse (ALT), alkaline phosphatase (ALP), concentration of total bilirubin in serum, and hydroxyproline content of the liver were significantly increased. The ST treatment (either 100 mg/kg/day or 200 mg/kg/day, p.o. for 4 weeks) in BDL/S rats reduced the serum AST, ALT and ALP activity levels significantly (p< 0.01). Similarly, when compared to the control group, the concentration of hydroxyproline in the livers of the BDL/S rats treated with 100mg or 200mg ST treated rats decreased by 40% and 33% respectively, when compared to the BDL/S control group (p<0.01). The morphological characteristics of fibrotic liver that were observed in the BDL/S control group, improved in the ST treated BDL/S group. In the fibrotic liver of BDL/S rats treated with ST, a marked reduction in the numbers of alpha smooth muscle cell actin positive stellate cells was observed. These results indicate that doses of either 100 or 200 mg/kg/day of methanol extract from S. tetrandra, had an antifibrotic effect in rats with liver fibrosis induced by bile duct ligation and scission.
