Clinical effect of rhubarb on the treatment of chronic renal failure: A meta-analysis.

Objective: 1) To evaluate the effificacy of rhubarb in the treatment of chronic renal failure (CRF); 2) To explore the safety for rhubarb-based therapy on chronic renal failure. Methods: The randomized and semi randomized controlled trials of Rhubarb in the treatment of chronic renal failure in medical electronic databases (up to September 2021) were searched, and meta-analysis was carried out by revman 5.3 software. Results: A total of 2,786 patients were included in 34 literatures, including 1,474 cases in the treatment group and 1,312 cases in the control group. The results of meta-analysis showed that Serum creatinine (SCR) [MD = 123.57, 95% Cl (111.59, 131.96)], Blood urea nitrogen (BUN) [MD = -3.26, 95% Cl (-4.22,-2.31)], Creatinine clearance rate (CCR) [MD = 3.95, 95% Cl (-0.03, 7.93)], Hemoglobin (Hb) [MD = 7.70, 95% Cl (-0.18, 15.58)] and Uric acid (UA) [MD = -42.79, 95% CI (-66.29, -19.29)]. The total effective rate of improving symptoms and signs in chronic renal failure patients [Peto or = 4.14, 95% Cl (3.32, 5.16)]. Conclusion: This systematic review and meta-analysis demonstrated that rhubarb has a positive therapeutic effect, which may provide confifidence and some theoretical reference for clinical application to a certain extent. Compared with the control group, rhubarb alone or traditional Chinese medicine compound containing Rhubarb can significantly reduce Serum creatinine, Blood urea nitrogen and Uric acid, increase Creatinine clearance rate, and improve the total effective rate of symptoms and signs. However, there is no evidence that rhubarb is more effective than the control group in increasing hemoglobin. In addition, due to the low quality of research methodology in the included literature, it is necessary to further study high-quality literature to evaluate its efficacy and safety.

Effectiveness and safety of Qingfei Dayuan granules for treating influenza and upper respiratory tract infections manifested by the pulmonary heat-toxin syndrome: A multicenter, randomized, double-blind, placebo-controlled trial.

Background: Patients diagnosed with influenza and upper respiratory tract infections (URTIs) have similar clinical manifestations and biochemical indices and a low detection rate of viral pathogens, mixed infection with diverse respiratory viruses, and targeted antiviral treatment difficulty in the early stage. According to the treatment strategy of "homotherapy for heteropathy" in traditional Chinese medicine (TCM), different diseases with the same clinical symptoms can be treated with the same medicines. Qingfei Dayuan granules (QFDY), a type of Chinese herbal preparation included in the TCM Diagnosis and Treatment Protocol for COVID-19 of Hubei Province issued by the Health Commission of Hubei Province in 2021, are recommended for patients suffering from COVID-19 with symptoms of fever, cough, and fatigue, among others. Additionally, recent studies have shown that QFDY effectively alleviates fever, cough, and other clinical symptoms in patients with influenza and URTIs. Materials and methods: The study was designed as a multicenter, randomized, double-blind, placebo-controlled clinical trial for treatment for influenza and URTIs manifested by pulmonary heat-toxin syndrome (PHTS) with QFDY. A total of 220 eligible patients were enrolled from eight first-class hospitals in five cities of Hubei Province in China and randomly assigned to receive either 15 g of QFDY or a placebo three times a day for 5 days. The primary outcome was the complete fever relief time. Secondary outcomes included efficacy evaluation of TCM syndromes, scores of TCM syndromes, cure rate of each single symptom, incidence of comorbidities and progression to severe conditions, combined medications, and laboratory tests. Safety evaluations mainly involved adverse events (AEs) and changes in vital signs during the study. Results: Compared with the placebo group, the complete fever relief time was shorter in the QFDY group, 24 h (12.0, 48.0) in the full analysis set (FAS) and 24 h (12.0, 49.5) in the per-protocol set (PPS) (p ≤ 0.001). After a 3-day treatment, the clinical recovery rate (22.3% in the FAS and 21.6% in the PPS) and cure rate of cough (38.6% in the FAS and 37.9% in the PPS), a stuffy and running nose, and sneezing (60.0% in the FAS and 59.5% in the PPS) in the QFDY group were higher than those in the placebo group (p < 0.05). The number of patients taking antibiotics for more than 24 h in the placebo group (nine cases) was significantly higher than that in the QFDY group (one case) (p < 0.05). There were no significant differences between the two groups in terms of scores of TCM syndromes, incidence of comorbidities or progression to severe conditions, combined use of acetaminophen tablets or phlegm-resolving medicines, and laboratory tests (p > 0.05). Meanwhile, no significant difference was found in the incidence of AEs and vital signs between the two groups (p > 0.05). Conclusion: The trial showed that QFDY was an effective and safe treatment modality for influenza and URTIs manifested by PHTS because it shortened the complete fever relief time, accelerated clinical recovery, and alleviated symptoms such as cough, a stuffy and running nose, and sneezing during the course of treatment.

Chinese herbal injections versus intrapleural cisplatin for lung cancer patients with malignant pleural effusion: A Bayesian network meta-analysis of randomized controlled trials.

Background: Malignant pleural effusion (MPE) is a common complication in patients with advanced lung cancer that can severely compromise the quality of life and limit life expectancy. Randomized controlled trials (RCTs) have shown that Chinese herbal injections (CHIs) may be beneficial in improving quality of life. This network meta-analysis (NMA) aims to explore several CHIs used for lung cancer patients with MPE. Methods: Seven databases were systematically searched for eligible RCTs from inception to November 2021. The primary outcome was the clinical effective rate. Secondary outcomes were the improvement rate of Karnofsky performance status (KPS) score and incidence of adverse events (AEs). The Cochrane risk of bias 2 tool was used to assess the quality of included studies. Data analysis was performed using STATA 16.0 and R software 4.1.0. Both pairwise meta-analysis and Bayesian NMA were conducted. Competing interventions were ranked using the surface under the cumulative ranking (SUCRA) probabilities. Evidence grading was evaluated using the Confidence in Network Meta-Analysis online software (https://cinema.ispm.unibe.ch/). Results: A total of 44 studies involving 2,573 patients were included. The combined Huachansu injection (HCS) with intrapleural cisplatin (cis-diamminedichloro-platinum, DDP) had the highest probability of improving the clinical effective rate (SUCRA, 84.33%). The Kangai injection (KA) combined with DDP had the most improvement rate of KPS score (SUCRA, 80.82%), while the Fufangkushen injection (FFKS) alone was more likely to reduce AEs including gastrointestinal reactions (SUCRA, 89.92%), leukopenia (SUCRA, 91.85%), and chest pain (SUCRA, 98.17%). FFKS combined with DDP ranked the best in reducing the incidence of fever (SUCRA, 75.45%). Conclusions: Our NMA showed that CHIs alone or combined with DDP could improve clinical effectiveness and quality of life and reduce AEs, compared to DDP alone. HSC and KA, combined with DDP, may be the most effective considering clinical effective rate and improvement of KPS score, respectively. FFKS, either used alone or in combination therapy with DDP, may be the best in reducing AEs. However, high-quality RCTs with larger sample sizes are needed to further support the evidence.

Comparative analysis of the efficacy and safety of herbal decoction CheReCunJin alone and combined with hydroxychloroquine for treating primary Sjögren's syndrome: A randomized controlled trial.

INTRODUCTION: There is currently no established effective treatment for primary Sjögren's syndrome (pSS). Traditional Chinese Medicine (TCM) is widely used in China and is reported to improve patient symptoms. This study compare the clinical efficacy and safety of herbal decoction CheReCunJin alone and combined with hydroxychloroquine for the treatment of pSS. METHODS: Seventy pSS patients without visceral involvement were randomly assigned in equal numbers to oral administration of CheReCunJin decoction only (group 1) or CheReCunJin decoction combined with hydroxychloroquine (group 2), Efficacy was evaluated after 3 months of treatment by the TCM syndrome and total effectiveness scores, European League Against Rheumatism (EULAR) Sjögren's Syndrome Patient Reported Index (ESSPRI), and Sjögren's Syndrome Disease Activity Index (ESSDAI), Schirmer's test, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and immunoglobulin G (IgG) levels. Safety was assessed. RESULTS: There were no differences in the baseline characteristics of the two groups. Compared with baseline values, the TCM syndrome, ESSPRI and ESSDAI scores, ESR, CRP, and Schirmer's test results improved significantly in both groups after treatment (p < 0.05). There was no significant difference in the TCM syndrome total effectiveness rate between the two groups (p = 0.31). Between-group differences in the changes in ESSPRI, ESSDAI, ESR, CRP, Schirmer's test, and IgG after treatment were not significant (all p> 0.05). Adverse reactions were reported in 5.88% of group 1 and 3.33% of group 2 participants (p = 0.83). CONCLUSION: CheReCunJin decoction alone was effective and safe for the treatment of pSS.

Danggui Buxue Decoction Ameliorates Inflammatory Bowel Disease by Improving Inflammation and Rebuilding Intestinal Mucosal Barrier.

OBJECTIVE: This study aimed to determine whether Danggui Buxue decoction (DGBX) can improve inflammatory bowel disease (IBD) by regulating immunity and promoting intestinal mucosal repair. METHOD: Dextran sulfate sodium (DSS) was used to induce the IBD model. Drugs (DGBX or saline) were administered to mice, which were randomly divided into three groups (control, model, and experimental groups). Hematoxylin and eosin staining of intestinal tissues was conducted to observe for morphological changes. Changes in cytokines and immune cells in the intestinal tissues were detected by enzyme-linked immunosorbent assay and flow cytometry. Immunofluorescence techniques were used to assess the status of the intestinal mucosal repair. RESULTS: This study found that treatment with DGBX can effectively improve the inflammatory state and pathological structure of the IBD model. DGBX not only can significantly change the composition of intestinal mucosal immune cells and promote the regression of inflammation but also significantly increase the proliferation of intestinal epithelial cells and promote the rapid repair of intestinal mucosal barrier injury compared with the model group (p < 0.05). CONCLUSION: Taking these results, DGBX shows promising protective effects on IBD by regulating immunity and promoting intestinal mucosal repair.

Effects of Jianpi Bushen Therapy for Treatment of CKD Anemia: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES: To evaluate the efficacy of Traditional Chinese Medicine, specifically Jianpi Bushen (JPBS) therapy, for treatment of patients with chronic kidney disease (CKD) anemia. METHODS: Randomized controlled trials of JPBS therapy for CKD anemia were searched and selected from seven electronic databases. The Cochrane collaboration tool was used to conduct methodological quality assessment. RevMan v5.3 software was utilized to perform data analysis. RESULTS: In total, 12 randomized controlled trials with 799 patients met the meta-analysis criteria. The aggregated results indicated that JPBS therapy is beneficial for CKD anemia by improving the clinical efficacy rate [risk ratio (RR) = 1.23, 95% confidence interval (CI): (1.14, 1.33), P < 0.00001] and hemoglobin (Hb) [weighted mean difference (WMD) = 9.55, 95% CI: (7.97, 11.14), P < 0.00001], serum ferritin (SF) [WMD = 6.22, 95% CI: (2.65, 9.79), P = 0.0006], red blood cell (RBC) [WMD = 0.31, 95% CI: (0.24, 0.38), P < 0.00001], hematocrit (HCT) [WMD = 2.95, 95% CI: (2.36, 3.54), P < 0.00001], serum creatinine (SCr) [WMD = 64.57, 95% CI: (33.51, 95.64), P < 0.0001], and blood urea nitrogen (BUN) levels [WMD = 3.76, 95% CI: (2.21, 5.31), P <0.00001]. Furthermore, evidence suggests that JPBS therapy is safe and does not increase adverse reactions compared with western medicine (WM) alone. CONCLUSION: This study found that JPBS therapy has a positive effect on the treatment of CKD anemia. However, more well-designed, double-blind, large-scale randomized controlled trials are needed to assess the efficacy of JPBS therapy in the treatment of CKD anemic patients.

Efficacy of Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules in treatment of COVID-19: A randomized controlled trial.

BACKGROUND: With the global epidemic of coronavirus disease (COVID-19), China has made progress in the prevention and control of the epidemic, and traditional Chinese medicine (TCM) has played a key role in dealing with the disease's effects on the respiratory system. This randomized controlled clinical trial evaluated the clinical efficacy and prognosis of Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules in patients with COVID-19. METHODS: A total of 283 patients participated in this clinical trial, and participants were randomly assigned to receive either 1) Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules or 2) Linahua granules, both combined with western medicine, or 3) western medicine alone for 14 days. At the end of the trial, the improvement and resolution rates of clinical symptoms and the rate of patients who progressed to severe disease status were evaluated. RESULTS: After 14 days of treatment, there was no significant difference in the improvement rate of clinical symptoms among the three groups (P > 0.05). Huoxiang Zhengqi dropping pills combined with Lianhua Qingwen granules has advantages in the treatment of nausea, vomiting and limb soreness. During treatment, all participants were treated with western medicine, and there was a significant difference in the use of macrolides among the three groups (P < 0.05). Specifically, the utilization rate of antibiotics in the western medicine group was significantly greater than that of the other two groups. Among the 182 diagnosed patients who completed this clinical trial, 13 patients progressed to severe disease, including one case in the Huoxiang + Lianhua group (1.6 %), five cases in the Lianhua group (8.6 %), and seven cases in the western medicine group (11.1 %). There was no statistical differences in this rate among the three groups (P > 0.05). However, the proportion of patients who progressed to severe disease in the Huoxiang + Lianhua group was the lowest, suggesting that the combination of TCM with western medicine has a potential advantage in improving the prognosis of patients with COVID-19. CONCLUSION: The use of Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules combined with western medicine may have clinical advantages for COVID-19 patients in improving clinical symptoms, reducing utilization rate of anti-infective drugs, and improving patient prognosis, which could pave the way for the use of complementary medicine in treating this infection.

Dangguibuxue decoction abolishes abnormal accumulation of erythroid progenitor cells induced by melanoma.

ETHNOPHARMACOLOGIC RELEVANCE: Dangguibuxue decoction (DGBX), is a well-known traditional Chinese medicine that contains two types of materials used to treat anemia. In this study, we aimed to explore the effect and mechanism of DGBX on abolishing erythroid progenitor cell (Ter119+CD71+) accumulation induced by melanoma. MATERIALS AND METHODS: B16/F10 melanoma cells were used to establish transplanted and metastatic melanoma models. DGBX or normal saline were administered intragastrically daily after the models were established. Tumor sizes and metastatic nodules were observed after tumor cell inoculation. To further test the function of DGBX on erythroid progenitor cell (EPC) accumulation and immunosuppressive abilities, the percentage of EPCs in the blood, and spleen were quantified with flow cytometry. The proportion of CD8+ T cells and related functional mediators, IFN-γ and TNF-α,were also quantified with flow cytometry. To further strengthen our in vivo observations, DGBX serum was prepared from the rats three days after DGBX was administered. Liquid chromatography-mass spectrometry was carried out to control the quality of the experiments. B16/F10 melanomacells were cultured with DGBX serum, and proliferation and apoptosis were observed with the CCK8 assay and AnnexinV/7AAD staining, respectively. EPCs were isolated from B16/F10-bearing mice and cultured under erythroid differentiation conditions. EPCs were treated with DGBX serum, and mature red cell proportions and cell denucleations were tested with flow cytometry and Giemsa staining of the cultured EPCs. Flow cytometry and qPCR were used to analyze the effects of DGBX on the expression of key molecules involved in erythroid development and to explore the mechanism by which DGBX relieves abnormal EPC accumulation. RESULTS: DGBX treatments significantly reduced B16 melanoma tumor sizes and metastatic nodules. Most importantly, our study strongly suggested that DGBX could alleviate anemia, and systematically enhance anti-tumor immune responses by reducing abnormal EPC accumulation. Moreover, DGBX serum treatments had no direct effect on tumor cell proliferation and apoptosis, but could promote EPCs to differentiate into mature red blood cells, in vitro. Mechanistically, at least in part, DGBX relieved abnormal EPC accumulation by altering the "master switch" transcription factors, Pu.1 and Gata-1. CONCLUSIONS: DGBX significantly alleviates abnormal tumor-induced EPC accumulation, inhibits B16 melanoma progression, and enhances anti-tumor immune responses.

Protective Effect of Zengye Decoction () on Submandibular Glands in Nonobese Diabetic Mice.

OBJECTIVE: To investigate the protective effect of Zengye Decoction (, ZYD) on the submandibular glands (SMGs) in nonobese diabetic (NOD) mice. METHODS: Twenty-seven female NOD mice were randomly equally divided into 3 groups: the model group, the hydroxychloroquine (HCQ) group, and the ZYD group. Nine C57/B6 mice served as the normal group. After 1-week acclimation, the HCQ and ZYD groups were intragastrically administered with HCQ and ZYD, respectively, and the normal and model groups were administered with normal saline. Changes in the salivary flow rate were observed. Mice from all 4 groups were sacrificed at the age of 20 weeks. The serum and SMGs were collected. Serum cytokines gamma-interferon (IFN-γ), interleukin-10 (IL-10) were detected by enzyme-linked immunosorbent assay. Histological changes in the submandibular glands were examined by hematoxylin and eosin staining. The mRNA expression of IFN-γ, IL-10 and vasoactive intestinal peptide (VIP) in the submandibular glands were measured by real-time polymerase chain reaction. RESULTS: Compared with the model group, the salivary flow of the ZYD group significantly increased (P<0.05), the extent of the histological changes was ameliorated (P<0.05), and the Th1/Th2 cytokine imbalance was remedied (P<0.05). In the ZYD-treated mice, the VIP mRNA was up-regulated (P<0.05). CONCLUSIONS: ZYD is beneficial in protecting structure and function of SMGs in NOD mice. The mechanism may be associated with the correction of the Th1/Th2 cytokine imbalance, and with the prevention of a progressive decline of the VIP level.

Clinical Efficacy and Safety of Total Glucosides of Paeony for Primary Sjögren's Syndrome: A Systematic Review.

OBJECTIVE: To evaluate the clinical efficacy and safety of total glucosides of paeony (TGP) for primary Sjögren's syndrome (pSS). METHODS: Eight electronic databases were searched from their inception to July 2016. Clinical randomized controlled trials (RCTs) were included. The study quality was evaluated according to the standard suggested in the Cochrane Handbook. RevMan 5.1 was used for statistical analysis. RESULTS: Seven RCTs involving 443 patients were included. The results showed that TGP combined with an immunosuppressant (IS) showed greater efficacy for improving the saliva flow test of pSS compared to immunosuppressant alone (WMD -6.88, 95% CI -9.02 to -4.74, and P < 0.00001). And the same trend favouring TGP-IS dual combination was found in Schirmer test (WMD 1.63, 95% CI 0.26 to 3.01, and P = 0.02), ESR (WMD 7.33, 95% CI -10.08 to -4.59, and P < 0.00001), CRP (WMD -6.00, 95% CI -7.17 to -4.83, and P < 0.00001), IgM (WMD = -0.42, 95% CI -0.70 to 0.13, and P = 0.004), and IgG (WMD -3.22, 95% CI -4.32 to -2.12, and P < 0.00001) analysis. However, TGP did not affect IgA (WMD 0.53, 95% CI -1.34 to -0.29, and P = 0.20). The adverse events manifested no significant differences between the two groups. CONCLUSIONS: The TGP-IS combination is superior to IS alone in the treatment of pSS. However, due to the low quality of included studies, high-quality RCTs are needed to confirm the beneficial effects of TGP.

[Probing into Second Pathological Factors of Sjögren's Syndrome].

Sjögren's syndrome is a chronic autoimmune disease with unclear etiology. From the point of etiology, Chinese medicine (CM) theory holds that pathological products like dry toxin, blood stasis are produced in the pathological process. They are both pathologic results and pathogenic factors for its further development. So pathological products are also named as second pathogenic factors. In this article, the concept of second pathogenic factors was sorted and defined. Main second pathogenic factors of Sjögren's syndrome were pinpointed, and their modern medical bases were analyzed. Authors came to a conclusion that clearing away second pathogenic factors is a key point in treating Sjögren's syndrome.
