The reporting checklist for Chinese patent medicine guidelines: RIGHT for CPM.

Existing reporting checklists lack the necessary level of detail and comprehensiveness to be used in guidelines on Chinese patent medicines (CPM). This study aims to develop a reporting guidance for CPM guidelines based on the Reporting Items of Practice Guidelines in Healthcare (RIGHT) statement. We extracted information from CPM guidelines, existing reporting standards for traditional Chinese medicine (TCM), and the RIGHT statement and its extensions to form the initial pool of reporting items for CPM guidelines. Seventeen experts from diverse disciplines participated in two rounds of Delphi process to refine and clarify the items. Finally, 18 authoritative consultants in the field of TCM and reporting guidelines reviewed and approved the RIGHT for CPM checklist. We added 16 new items and modified two items of the original RIGHT statement to form the RIGHT for CPM checklist, which contains 51 items grouped into seven sections and 23 topics. The new and revised items are distributed across four sections (Basic information, Background, Evidence, and Recommendations) and seven topics: title/subtitle (one new and one revised item), Registration information (one new item), Brief description of the health problem (four new items), Guideline development groups (one revised item), Health care questions (two new items), Recommendations (two new items), and Rationale/explanation for recommendations (six new items). The RIGHT for CPM checklist is committed to providing users with guidance for detailed, comprehensive and transparent reporting, and help practitioners better understand and implement CPM guidelines.

Efficacy and safety of acupuncture therapy combined with conventional pharmacotherapy in the treatment of systemic lupus erythematosus: A systematic review and meta-analysis.

BACKGROUND: Currently, the mainstream treatments for systemic lupus erythematosus (SLE) are based on glucocorticoids and immunosuppressants, which are known to have considerable adverse effects. This meta-analysis is aimed at confirming the efficacy and safety of acupuncture therapy in combination with traditional medications in the treatment of SLE. METHODS: Multiple databases were searched for randomized controlled trials using acupuncture therapy in combination with conventional pharmacotherapy for the treatment of SLE, from the establishment of the database to March 2023. Study selection, data collection, as well as quality assessment were conducted by 2 reviewers independently. RevMan 5.4 and Stata 17 software were used for Meta-analysis. RESULTS: Seven eligible studies involving 514 patients with SLE were included. Meta-analysis demonstrated that in SLE patients, extra treatment with acupuncture was superior to drug therapy alone in improving the overall response rate (RR = 1.20, 95% confidence intervals [1.11, 1.29], P < .00001, heterogeneity P = .69, I2 = 0%) and regulating immunological indicators (C3, C4, IgG, T lymphocyte subpopulation, IL-6, ds-DNA, ESR) while reducing TCM symptom scores, the SLE Disease Activity Index (SLEDAI) and the incidence of adverse events on treatment (P ≤ 0.05). Additionally, it was able to reduce BUN, Scr and 24 hours urine protein, suggesting that acupuncture treatment had a protective effect on the kidneys. CONCLUSIONS: Acupuncture therapy combined with conventional pharmacotherapy is an efficient and safe way in the treatment of SLE. However, the conclusions drawn from this meta-analysis have some limitations due to the small number and uneven quality of the included studies, leading to heterogeneity and bias. Thus more relevant high-quality randomized controlled trials are needed for further evaluation in the future.

Jiedu-Quyu-Ziyin Fang (JQZF) inhibits the proliferation and activation of B cells in MRL/lpr mice via modulating the AKT/mTOR/c-Myc signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Jiedu-Quyu-Ziyin Fang (JQZF) is a new herbal formula improved based on "Sheng Ma Bie Jia Tang" in the Golden Chamber, has been proved to be effective in the treatment of SLE. The ability of JQZF to prevent lymphocyte growth and survival has been demonstrated in earlier investigations. However, the specific mechanism of JQZF on SLE has not been fully investigated. AIM OF THE STUDY: To reveal the potential mechanisms of JQZF inhibiting B cell proliferation and activation in MRL/lpr mice. MATERIALS AND METHODS: MRL/lpr mice were treated with low-dose, high-dose JQZF and normal saline for 6 weeks. The effect of JQZF on disease improvement in MRL/lpr mice was studied using enzyme-linked immunosorbent assay (ELISA), histopathological staining, serum biochemical parameters and urinary protein levels. The changes of B lymphocyte subsets in the spleen were analyzed by flow cytometry. The contents of ATP and PA in B lymphocytes from the spleens of mice were determined by ATP content assay kit and PA assay kit. Raji cells (a B lymphocyte line) were selected as the cell model in vitro. The effects of JQZF on the proliferation and apoptosis of B cells were detected by flow cytometry and CCK8. The effect of JQZF on the AKT/mTOR/c-Myc signaling pathway in B cells were detected via western blot. RESULTS: JQZF, especially at high dose, significantly improved the disease development of MRL/lpr mice. Flow cytometry results showed that JQZF affected the proliferation and activation of B cells. In addition, JQZF inhibited the production of ATP and PA in B lymphocytes. In vitro cell experiments further confirmed that JQZF can inhibit Raji proliferation and promote cell apoptosis through AKT/mTOR/c-Myc signaling pathway. CONCLUSION: JQZF may affect the proliferation and activation of B cells by inhibiting the AKT/mTOR/c-Myc signaling pathway.

Data-mining-based of ancient traditional Chinese medicine records from 475 BC to 1949 to potentially treat COVID-19.

Traditional Chinese Medicine (TCM) plays a role in preventing and treating COVID-19 in China. Based on the manifestations and symptoms of COVID-19, our study used the data mining method to summarize related therapeutic experience left by predecessors who used TCM to treat epidemics in their eras. Initially, we collected abundant medical records with similar manifestations of COVID-19 in Chinese ancient times. The key words including wen (), yi (), li (), and zhang () were searched in ZhongyiZhiku (https://www.zk120.com/) from Warring States Period (475 BC-221 BC) to the Republic of China era (1912-1949) to locate ancient medical records according to inclusion criteria and exclusion criteria. Moreover, COVID-19-related manifestations and corresponding medications in those records were categorized. Eventually, Traditional Chinese Medicine Inheritance Support System version 2.5 was used to build a medical record database of TCM treating COVID-19. Our study collected 263 epidemic medical records comprising COVID-19 related manifestations and found that Chinese Materia Medica (CMM) combinations excavated from ancient medical records included Ren Shen Bai Du San, Wu Ling San, Xiao Chai Hu Tang, Da Cheng Qi Tang, Da Chai Hu Tang, Ling Gui Zhu Gan Tang, and Qing Wen Bai Du Yin. The recurrent CMMs with a high frequency for treating COVID-19 manifestations were Scutellariae Radix (Huang Qin), Paeoniae Alba Radix (Bai Shao), Poria (Fu Ling), and Bupleuri Radix (Chai Hu). Our study suggests that TCM might offer new therapeutic strategies for COVID-19.

A Promising Target of Langchuangding Prescription Treating Systemic Lupus Erythaematosus Integrated Network Pharmacology with HPLC-MS and Molecular Docking.

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disorder affecting almost any organ system without effective treatment. Based on accumulating evidence, activated T cells are key cause promoting the pathogenesis of SLE. A traditional clinic Langchuangding formula (LCD) is an effective clinical traditional Chinese medicine prescription for SLE with few side effects and good patient compliance. However, the mechanism of how LCD affects SLE remains unclear. METHODS: Targets related to LCD and SLE were predicted and overlapped to construct protein-protein interaction (PPI) for screening core target. Subsequently, flow cytometry analysis and Western-blot method were used to verify the expression levels of target gene in LCD serum treated-Jurkat T cells. The main compounds of LCD were identified by HPLC-MS and further docked with the core targe. RESULTS: 283 protein targets in LCD, 1498 SLE targets and 150 common targets were obtained to construct protein-protein interaction (PPI). Network pharmacology results suggested that LCD was closely related to CASP3 target. To verify the prediction of pharmacological mechanism of LCD treatment for SLE, we investigated the anti-proliferative effects of LCD-treated rat serum on ß-oestradiol (300 pg/mL)-activated Jurkat T cells in vitro using a CCK-8 kit and flow cytometry analysis and then analyzed the CASP3 expression levels. Vitro experiments confirmed that LCD serum could suppress the proliferation (p < 0.05) and induce apoptosis of the activated T cells through up-regulating CASP3 expression levels. Interactions between CASP3 target and LCD were further validated integrating HPLC-MS analysis and molecular docking. CONCLUSIONS: The results showed that LCD could relieve SLE, which might be attributed to inducing the activated T cells apoptosis by up-regulating CASP3 expression levels. The network pharmacology and molecular docking approach provide a new insight for deepening understanding about TCM. LCD potentially represents a promising therapeutic prescription for SLE supplement treatment with no adverse effects.

The Tai Chi Flap: A Novel Design for the Radial Forearm Flap.

OBJECTIVE: Tai Chi is an ancient philosophy used to explain the universe. The Tai Chi symbol is represented by Yin/Yang fishes. The authors describe a novel radial forearm flap (RFF) design for the reconstruction of circular defects based on the Tai Chi symbol. METHODS: Eleven consecutive patients with craniofacial skin or mucus defects underwent reconstruction with a Tai Chi RFF. Patient perioperative and follow-up information was collected. RESULTS: The diameter of the Tai Chi RFF was 5 to 6 cm. All flaps healed uneventfully without ischemic problems, and all donor site defects were closed primarily without skin grafts. Remarkably, 2 patients received a tattoo to mark the Tai Chi symbol and greatly appreciate the shape of the flap. CONCLUSIONS: The Tai Chi flap is an economically friendly flap design that can be used to prevent skin grafts while providing psychological comfort to patients.

Yunpi Qufeng Chushi Formula for Pre-Rheumatoid Arthritis: Study Protocol for a Multiple-Center, Double-Blind, Placebo-Controlled Randomized Controlled Trial.

Introduction: Rheumatoid arthritis (RA) is an autoimmune disease characterized by progressive bone erosion on diarthrodial joints. RA patients usually experienced three stages before final diagnosis: the health period, the pre-clinical period (immune response exists without clinical symptoms), and the pre-RA period (immune response exists with mild inflammatory manifestation). Presently, there is seldom guidance referring to early intervention which is a benefit for stable disease conditions and low morbidity. Prophylactic treatment is a major feature of traditional Chinese medicine (TCM). In this present study, a multi-center, double-blind, placebo-controlled clinical trial is carried out to evaluate both efficacy and safety in preventing RA progression on Yunpi Qufeng Chushi formula (YQCF). Method: The multi-center, double-blind, placebo-controlled clinical trial is conducted in 13 hospitals nationwide. A total of 390 patients ages between 18 and 70 will be recruited in the trial. They will be randomly assigned to the intervention group (YQCF) and placebo group. The follow-up visit will be taken every 3 months from baseline to 1 year. Diagnosis, disease activity scores, clinical disease activity index (CDAI), simplified disease activity index (SDAI), TCM syndrome scores, and safety assessments will be recorded at every visit. Joint color doppler ultrasound, health assessment questionnaire-disability index (HAQ-DI), and functional assessment of chronic illness therapy-fatigue (FACIT-F) will be recorded at baseline and the last visit. Discussion: This work will provide evidence of YQCF in preventing RA progression. However, whether early intervention would benefit the controlling RA disease still needs a long-term follow-up. Ethics and dissemination: Protocol version 2 (201910-1). This research was approved by the medical ethics committee of Zhejiang Chinese Medical University (2019-045). Results will be published in a peer-reviewed academic journal. Trial registration numbers: http://www.chictr.org.cn/index.aspx, ChiCTR1900024166.

Guidelines on the treatment with integrated traditional Chinese medicine and western medicine for severe coronavirus disease 2019.

Severe Coronavirus Disease 2019 (COVID-19) is characterized by numerous complications, complex disease, and high mortality, making its treatment a top priority in the treatment of COVID-19. Integrated traditional Chinese medicine (TCM) and western medicine played an important role in the prevention, treatment, and rehabilitation of COVID-19 during the epidemic. However, currently there are no evidence-based guidelines for the integrated treatment of severe COVID-19 with TCM and western medicine. Therefore, it is important to develop an evidence-based guideline on the treatment of severe COVID-19 with integrated TCM and western medicine, in order to provide clinical guidance and decision basis for healthcare professionals, public health personnel, and scientific researchers involved in the diagnosis, treatment, and care of COVID-19 patients. We developed and completed the guideline by referring to the standardization process of the "WHO handbook for guideline development", the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the Reporting Items for Practice Guidelines in Healthcare (RIGHT).

Kunxian Capsule for Rheumatoid Arthritis: Inhibition of Inflammatory Network and Reducing Adverse Reactions Through Drug Matching.

Tripterygium wilfordii Hook.f and Tripterygium hypoglaucum (H.Lév.) Hutch is effective herbs to prevent aggravation of Rheumatoid arthritis (RA). However, both of them show severe side effects in the reproductive system and other systems. Kunxian Capsule (KX), a Traditional Chinese Medicine (TCM) patent prescription, comprised of 4 herbs, including H.Lév. Hutch, is reported to be an available prescription in treating RA with fewer side effects as compares to Tripterygium tablets. To reveal the pharmacological mechanism of KX in RA treatment and side effect alleviation, we collected related information of KX from open-access databases and performed various analyses. 1354 targets were identified in KX. These targets were enriched in the calcium signaling pathway, cAMP signaling pathway, cGMP-PKG signaling pathway and PI3K-AKT signaling pathway, forming biological functions, such as cofactor binding, coenzyme binding, etc. These pathways or functions mostly affect cell cycle, differentiation, and maturation of Th17 cells, macrophage, and synovial fibroblast. These targets also act on the IL-17 signaling pathway, Th17 cell differentiation signaling pathway and TNF signaling pathway, which is related to inflammation response inhibition. Next, a disease network was constructed, which indicated IMPDH2, MTHFD1 are the key genes answering for the side effects of H.Lév. Hutch. The side effect-related genes lead to the negative regulation of nucleic acid, which could be restored by the rest 3 herbs through some positive amino acid metabolism. In conclusion, KX is a relatively safe alternative approach in RA intervention.

Moxibustion for the treatment of ankylosing spondylitis: a systematic review and meta-analysis.

BACKGROUND: To systematically evaluate the efficacy of moxibustion in the treatment of ankylosing spondylitis (AS). METHODS: Seven electronic databases were systematically searched for relevant studies for inclusion from databases inception to December 31, 2018. Randomized controlled trials investigating the efficacy of moxibustion for AS treatment versus Western medicine (Wm) treatment were included for systematic review and meta-analysis. Effect estimates were pooled using the fixed or random-effects models. Between-study heterogeneity and publication bias were also assessed. Stratification analyses were further performed based on the treatment plan of experimental groups. RESULTS: Twenty-six studies were eligible for inclusion with a total of 1,944 AS patients. Meta-analysis showed that compared with those receiving Wm treatment alone, patients receiving moxibustion combined with Wm treatment or moxibustion alone had a higher clinical efficacy rate [odds ratio (OR) =4.21, 95% confidence interval (CI): 2.91 to 6.10, P<0.001 for moxibustion combined with Wm versus Wm; OR =2.43, 95% CI: 1.62 to 3.65, P<0.001 for moxibustion alone versus Wm]. In addition, patients receiving moxibustion combined with Wm treatment had lower levels of C-reactive protein [weighed-median difference (WMD) =-6.33, 95% CI: -9.64 to -3.01, P<0.001] and erythrocyte sedimentation rate (WMD =-7.86, 95% CI: -11.26 to -4.46, P<0.001) after treatment, respectively. Furthermore, moxibustion could also improve Schober test scores (WMD =0.85, 95% CI: 0.15 to 1.55, P=0.017), occipital-wall distances (WMD =-0.55, 95% CI: -0.92 to -0.19, P=0.003), and finger-ground distances (WMD =-3.64, 95% CI: -5.61 to -1.68, P<0.001) of AS patients. CONCLUSIONS: This study suggests that moxibustion is an effective complementary treatment for AS patients. However, further large-scale multicenter clinical trials are needed to confirm these findings.

Innovated formulation of TCM pangolin scales to develop a nova therapy of rheumatoid arthritis.

Pangolin scale (PS) is a traditional Chinese medicine (TCM) for treating rheumatic arthritis (RA), and diverse medicinal formulations and therapeutic properties of PS have proved great potential to supplement conventional treatments in integrative medicine-based strategies. However, few studies have investigated how different PS formulations can impact the management of RA. Herein, we developed an innovative formulation of PS processed with vinegar (PSP) and evaluated it by comparing with the traditional decoction of PS (PSD) and non-steroidal anti-inflammatory drug (NASID) (i.e., meloxicam) in a RA Sprague Dawley rat model, which is induced with a complete Freund's adjuvant (CFA). The anti-inflammatory activities were evaluated by paw edema measurement, arthritic score, histopathological examination, pro-inflammatory cytokines (IL-1ß and TNF-α) production and the whole blood viscosity. PSP treatments (249.0 mg/kg.bw) from day 14-42 alleviated paw edema (P < 0.001), arthritic index (score 0-1.5) and the inflammatory cell infiltration in the ankle joint, which may be attributed to inhibiting the production of TNF-α (P < 0.01) and IL-1ß (P < 0.05) in the serum. Although PSP is with fewer efficacies than meloxicam, it outperformed traditional formulation PSD (830 mg/kg.bw) in all above mentioned metrics. Furthermore, PSP exhibited a unique effect on reducing whole blood viscosity (P < 0.05) unobserved in meloxicam intervention. The present study demonstrates that PSP showed more efficient anti-inflammatory activity than PSD in CFA-induced RA rats, possibly due to the presence of higher levels of active ingredients. Thus, PSP may be a promising therapy for anti-inflammation in RA and can be integrated with conventional treatments, particularly for long-term RA management in an integrative treatment strategy.

Purification, characterization and anti-tumor activity of a pectic-type polysaccharide isolated from Ficus pandurata H.

A homogeneous polysaccharide (FP2) with 83.3 kDa molecular weight was obtained from the aerial parts of Ficus pandurata H. (Moraceae) by Sevag, anion-exchange chromatography and gel-filtration chromatography. On the basis of composition analysis, infrared spectra (IR) and nuclear magnetic resonance (NMR) experiments, FP2 is a linear pectin with a main chain composed of →4)-α-D-GalpA-(1→. We investigated the anti-proliferative activity and its underlying mechanism of FP2 in HeLa cancer cells, using MTT assay and western blot analysis, respectively. Treatment with FP2 in HeLa cancer cells showed anti-proliferation effect and up-regulated the expression levels of caspase-3 and cleaved-PARP. IC50 values were 31.50 and 22.62 µg/ml for 24 h and 48 h, respectively. FP2 has potential of antitumor possibly due to apoptosis induction mediated through caspase-3 activation and cleavage of PARP. The results suggest that FP2 may be a promising plant polysaccharide targeting for anticancer therapy through activating the apoptotic pathway.

Effect of a Traditional Chinese Medicine Formula (CoTOL) on Serum Uric Acid and Intestinal Flora in Obese Hyperuricemic Mice Inoculated with Intestinal Bacteria.

CoTOL is a traditional Chinese medicine (TCM) formula in clinics for treating gout and hyperuricemia, especially in obese patients with recurrent attacks. However, fewer studies have investigated how CoTOL impacts the intestinal flora in reducing uric acid. In the present, we analyze the bacteria targeted by ingredients of CoTOL and evaluate the effects of CoTOL on uric acid and intestinal flora in a mice model of obese hyperuricemia inoculated with xanthine dehydrogenase- (XOD-) producing bacteria, Streptococcus faecalis. Firstly, ingredients of herbs in CoTOL and gene target by these ingredients were retrieved from TCMID 2.0, and these genes were screened by DAVID Bioinformatics Resources 6.8, deciphered to retrieve the bacteria. Then, 3-4-week-old male C57bl/6j mice were randomly divided into 6 groups and fed with high fat diet for 8 weeks up to obesity standard. The mice were inoculated intragastrically with 5 × 109 CFU Streptococcus faecalis 3 times at the 5th, 6th, and 7th week and intragastrically administrated with uricase inhibitor, potassium-oxonate (PO, 250 mg/kg), to induce hyperuricemia at the 8th week, once a day for 7 consecutive days, respectively (IB model). IB model plus CoTOL (0.4 ml/20g) and allopurinol (40 mg/kg) were administrated by gavage at the 5th week, once a day for 4 weeks. The feces and blood in each group were sampled at the 4th and 8th week. With no bacteria inoculation, CoTOL, allopurinol, and blank group were treated with CoTOL and allopurinol or water, respectively. 44 species of bacteria (i.e., Enterococcus faecalis, Streptococcus, etc.) genes were targeted by 6 ingredients of 6 herbs in CoTOL. Inoculation with Streptococcus faecalis significantly caused the elevation of uric acid and the change of intestinal flora structure, whereas treatment with CoTOL significantly increased the abundance of Akkermansia and those of Bacteroides and Alloprevotella decreased. Furthermore, CoTOL exhibited a unique effect on reducing weight unobserved in allopurinol intervention. The present study, for the first time, demonstrated that CoTOL has beneficial effects on hyperuricemia and overweight, which may be attributed to regulating material metabolism and improving the structure or function of intestinal flora. Thus, CoTOL may be a promising therapy for hyperuricemia and overweight in chronic gout management and can be integrated with conventional treatments.

Qu-Zhuo-Tong-Bi Decoction Alleviates Gouty Arthritis by Regulating Butyrate-Producing Bacteria in Mice.

Qu-zhuo-tong-bi decoction (QZTBD) is a traditional Chinese medicine prescription used to treat hyperuricemia and gout with no obvious adverse effects. However, the mechanism by which QZTBD treats gout has not been fully explored. Here, we investigated the effects of QZTBD on gouty arthritis and its therapeutic mechanism from the perspective of the gut microbiome. Our results demonstrated that QZTBD was effective for reducing serum uric acid level and attenuating paw edema and mechanical allodynia. QZTBD promoted the abundance of butyrate-producing bacteria and the production of SCFAs. Further study revealed that QZTBD restored the intestinal barrier function, modulated the expression of GPR43 and ABCG2, suppressed the activity of key glycolysis-related enzymes, and inhibited the generation of intestinal inflammatory factors. These findings suggested that QZTBD is an effective therapeutic drug for gouty arthritis. Butyrate-producing bacteria and its metabolites SCFAs might act as a potential target of QZTBD.

Analysis of brain metabolites by gas chromatography-mass spectrometry reveals the risk-benefit concerns of prednisone in MRL/lpr lupus mice.

OBJECTIVE: Neuropsychiatric systemic lupus erythematosus (NPSLE) is a common cause of disability in systemic lupus erythematosus (SLE). This study aims to investigate the metabolic changes in the hypothalamus and frontal cortex in lupus-prone MRL/lpr mice. METHODS: Metabolic changes were analyzed using gas chromatography-mass spectrometry (GC-MS). RESULTS: According to the principal component analysis (PCA), the metabolic profiles were different between the frontal cortex and hypothalamus, but they were comparable between MRL/lpr and MRL/MpJ mice (16 weeks of age). By OPLS-DA, eight cortical and six hypothalamic differential metabolites were identified in MRL/lpr as compared to MRL/MpJ mice. Among these differential metabolites, we found a decrease of N-acetyl-L-aspartate (NAA, a potential marker of neuronal integrity), an increase of pyruvate and a decrease of glutamate in the frontal cortex but not in the hypothalamus. Prednisone treatment (3 mg/kg from 8 weeks of age) relieved the decrease of NAA but further increased the accumulation of pyruvate in the frontal cortex, additionally affected eight enriched pathways in the hypothalamus, and led to significant imbalances between the excitation and inhibition in both the frontal cortex and hypothalamus. CONCLUSION: These results suggest that the frontal cortex may be more preferentially affected than the hypothalamus in SLE. Prednisone disrupted rather than relieved metabolic abnormalities in the brain, especially in the hypothalamus, indicating that the risk-benefit balance of prednisone for SLE or NPSLE remains to be further evaluated.

[Analysis on mechanisms and medication rules of herbal prescriptions for gout caused by heat-damp accumulation syndrome based on data mining and network pharmacology].

To mine the medication rules of herbal prescriptions for gout caused by heat-damp accumulation syndrome, and explore the possible mechanism of the core herbs, we collected the relevant literature of gout caused by heat-damp accumulation syndrome in CNKI, medication rules of herbal prescriptions are analyzed by using TCMISS(V2.5) software, and the compatibility of core drugs and new prescriptions were mined.KEGG pathway analysis was performed by BATMAN-TCM, an online analysis tool, and the potential signaling pathways of core drugs compatibility to treat gout caused by heat-damp accumulation syndrome were revealed. The results showed that six core drugs and three new prescriptions were found out of the 136 prescriptions. The core compatibility herbs in clinical treament of gout caused by heat-damp accumulation syndrome, Phellodendri Chinrnsis Cortex, Achyranthis Bidentatae Radix and Achyranthis Bidentatae Radix, which potential signaling pathways were purine metabolic pathway and neura activity ligand receptor interaction signaling pathway. Therefore, for gout caused by heat-damp accumulation syndrome, the mainly used therapies of TCM were clearing heat and drying dampness,inducing diuresis for removing edema, dispeling wind and eliminating dampness. The mechnisms of core compatibility herbs may be achieved through the intervention of purine metabolic pathway and neural activity ligand receptor interaction signaling pathway.

Effect of Lang-Chuang-Ding Decoction () on DNA Methylation of CD70 Gene Promoter in Peripheral Blood Mononuclear Cells of Female Patients with Systemic Lupus Erythematosus.

OBJECTIVE: To investigate the effect of Lang-chuang-ding Decoction (, LCD) on the expression of DNA methylation of CD70 gene promoter in peripheral blood mononuclear cells (PBMCs) of females with systemic lupus erythematosus (SLE). METHODS: PBMCs isolated from female patients with SLE or healthy donors were cultured and treated with LCD medicated serum or normal serum for 24 or 48 h. The mRNA expressions of CD70 gene in PBMCs were detected by reverse transcription polymerase chain reaction (PCR); the DNA methylation of the CD70 gene promoter region was detected by methylation-specific PCR. RESULTS: After treated with medicated serum for 48 h, the mRNA expression levels of CD70 in PBMCs of SLE patients were signifificantly higher than those of healthy donors (P<0.05); the DNA methylation levels of CD70 promoter region in PBMCs of SLE patients treated with medicated serum for 48 h were signifificantly higher than those treated with fetal bovine serum (P<0.01). CONCLUSION: LCD could inhibit CD70 gene expression in PBMCs of SLE patients by promoting the DNA methylation of CD70 gene promoter.

Hypouricemic and arthritis relapse-reducing effects of compound tufuling oral-liquid in intercritical and chronic gout: A double-blind, placebo-controlled, multicenter randomized trial.

TRIAL DESIGN: In the double-blind, randomized, controlled trial, we aimed to evaluate the effects of compound tufuling oral liquid (CoTOL) on serum uric acid (sUA) levels and recurrence of acute gouty arthritis in intercritical and chronic gout treatment. METHODS: A total of 210 patients with gout were screened from 8 hospitals to observe the sUA and acute gouty arthritis recurrence rate-reducing effects of CoTOL in intercritical and chronic gout during a 12-week treatment. We treated 139 and 71 patients with CoTOL and the placebo, respectively, and evaluated their sUA levels, acute gouty arthritis recurrence rate, and adverse events at week 0, 6, and 12. RESULTS: Twenty-five and 12 patients in the treatment and control groups, respectively, had interrupted treatments, whereas 114 and 59 cases, respectively, completed their treatments. At the end of the 12-week treatment, the average decrease in sUA was 74.26 (95% confidence interval [CI]: 56.74-91.77 µmol/L) and 28.81 µmol/L (95% CI: 4.91-52.71 µmol/L) in the treatment and control groups, respectively (P = 0.004). The average decrease rate of sUA was 12.76% (95% CI: 9.82%-15.70%) and 4.57% (95% CI: 0.42%-8.71%) in the treatment and control groups, respectively (P = 0.004), and the gouty arthritis recurrence rate of the treatment group was lower than that of the control group (from week 6 to 12, 21.93% and 50.88% in the treatment and control group, respectively, P < 0.001; from baseline to week 12, 38.5% and 63.16%, respectively, P = 0.003). Severe adverse events were not observed in either groups, and fewer leucopenia incidences were observed in the treatment group than those in the control group (3/139 vs. 7/71, respectively, P = 0.033). CONCLUSION: CoTOL reduced sUA levels and effectively prevented acute arthritis recurrence in intercritical and chronic gout without serious adverse events.

To Unveil the Molecular Mechanisms of Qi and Blood through Systems Biology-Based Investigation into Si-Jun-Zi-Tang and Si-Wu-Tang formulae.

Traditional Chinese Medicine (TCM) is increasingly getting clinical application worldwide. But its theory like QI-Blood is still abstract. Actually, Qi deficiency and blood deficiency, which were treated by Si-Jun-Zi-Tang (SJZT) and Si-Wu-Tang (SWT) respectively, have characteristic clinical manifestations. Here, we analyzed targets of the ingredients in SJZT and SWT to unveil potential biologic mechanisms between Qi deficiency and blood deficiency through biomedical approaches. First, ingredients in SWT and SJZT were retrieved from TCMID database. The genes targeted by these ingredients were chosen from STITCH. After enrichment analysis by Gene Ontology (GO) and DAVID, enriched GO terms with p-value less than 0.01 were collected and interpreted through DAVID and KEGG. Then a visualized network was constructed with ClueGO. Finally, a total of 243 genes targeted by 195 ingredients of SWT formula and 209 genes targeted by 61 ingredients of SJZT were obtained. Six metabolism pathways and two environmental information processing pathways enriched by targets were correlated with 2 or more herbs in SWT and SJZT formula, respectively.

Effect of a traditional Chinese medicine prescription Quzhuotongbi decoction on hyperuricemia model rats studied by using serum metabolomics based on gas chromatography-mass spectrometry.

Morbidity of hyperuricemia has constantly increased in population in decades, and hyperuricemia has proved to be an important risk factor for gout, cardiovascular diseases and others. Many urate-lowering drugs have unfavorable side effects and drug interactions. Quzhuotongbi decoction (QZTBD) is an empirical traditional Chinese medicine prescription for clinical therapy of hyperuricemia without serious adverse effects. In the study, we investigated the effects of QZTBD on urate and other metabolites in the sera of hyperuricemia model rats. Hyperuricemia model was established by orally administering yeast extract paste, and allopurinol served as a positive control drug. Serum metabolomics was performed by using a gas chromatography-mass spectrometry (GC-MS) method. Student's t-test and the principal component analysis (PCA) were employed to find the metabolic perturbations in hyperuricemia model rats. The levels of urate, lactate, pyruvate and ornithine were significantly increased, and xanthine, glyconic acids (ribonate, galactonate), amino acids (aspartate, proline, glutamine, serine, pyroglutamate, glutamate) and glucose were down-regulated greatly in the model rats. It demonstrated that nucleotide metabolism, amino acid metabolism and glycolytic pathway were disturbed by yeast administration. An orthogonal signal correction-partial least-squares discriminant analysis (OSC-PLS DA) was performed to assess the effects of yeast administering and drug treatment. 11 significantly distinctive metabolites among four groups were defined according to the variable importance for project values (VIP>1) and univariate ANOVA (p value<0.05). As compared to the model rats, the serum uric acid levels were lowered markedly under the treatment of allopurinol or QZTBD. Aspartate and glutamine involved in purine metabolism, were raised to normal level as well. The different influences on xanthine, glutamate pyroglutamate and galactonate suggested there were different mechanisms of two drugs in urate-lowering therapy. Our finding proved that QZTBD can efficiently lower the level of serum uric acid in a different way from allopurinol, which suggested that QZTBD based on the theory of TCM could be an effective therapeutic option for hyperuricemia.
