Chinese patent medicine as a complementary and alternative therapy for type 2 diabetes mellitus: A scoping review.

OBJECTIVE: This scoping review aims to document Chinese Patent Medicines (CPMs) for Type 2 Diabetes Mellitus, explore whether CPMs can improve patients' health outcomes, and set priorities in addressing research gaps in this area. METHODS: Following the framework of PRISMA-SCr, we proposed the research questions based on PICOS principle, and searched the CPMs for T2DM from three drug lists, followed by a systematic search of the literature in eight databases from their inception to June 22, 2023. Then, we developed the eligibility criteria and systematically reviewed the relevant studies, retained the studies about CPMs for T2DM, extracted the related data, and identified the differences across studies in structured charts. RESULTS: A total of 25 types of CPMs were extracted from the three drug lists. Radix astragali appeared most frequently (19 times) among the herbal medicinal ingredients of CPMs. A total of 449 articles were included in the full-paper analysis ultimately, all of which were about 20 types of CPMs, and there were no related reports on the remaining five CPMs. Except about a quarter (25.39 %, 114/449) using CPMs alone, the remaining studies all involved the combination with oral hypoglycemics for T2DM. Biguanides are the most common drugs used in combination with CPMs (50.14 %, 168/335). Fasting plasma glucose (FPG) is the most frequently reported outcomes in efficacy evaluation (82.41 %, 370/449). CONCLUSION: There are a total of 25 types of CPMs currently available for T2DM patients. However, the volume of related evidence on these CPMs varies. It is necessary to standardize the combined use of CPMs and conventional medicine and select appropriate outcomes in future studies.

[Academic characteristics of contemporary famous traditional Chinese medicine experts and schools in treatment of chronic renal failure based on SrTO].

According to the systematic review of text and opinion(SrTO) developed by the Joanna Briggs Institute(JBI), this study integrated the evidence of the medical cases, papers, medical experience, and other related research of famous experts and schools on the treatment of chronic renal failure in the field of traditional Chinese medicine(TCM) nephropathy, analyzed the academic characteristics and influencing factors from the aspects of the principle, method, recipe, and medicines, and explored the internal logic and law of inheritance and innovation in TCM nephropathy. A total of 36 famous TCM experts and 4 schools were included. The work areas are concentrated in North and South China. 94.0% of the famous TCM experts have experienced master-disciple teaching. 27.8% have studied TCM through family succession. 38.9% have been taught by multiple famous teachers. And 5.6% have not experienced master-disciple teaching. In terms of principle, method, recipe, and medicines, many innovations have been made, with 30.6% of famous TCM experts proposing new theories, 11.1% advocating staged treatment of chronic renal failure, and 47.2% summarizing the treatment methods. The formation of the academic thoughts of contemporary famous TCM experts and schools on the treatment of chronic renal failure is closely related to the learning mode, era, and work area. Contemporary famous TCM experts and schools have the academic characteristics of combining classical and clinical theories and paying more attention to TCM with western medicine supplemented. The field of TCM nephropathy has the characteristics of simultaneous inheritance and innovation. On the basis of inheriting the classical theories of TCM, it absorbs modern medical theories, combines clinical diagnosis with the syndrome and treatment law of contemporary diseases, and makes innovations in principle, method, recipe, and medicines, which has significant clinical efficacy in the treatment of chronic renal failure.

Efficacy of Traditional Chinese Medicine on Animal Model of IgA Nephropathy: A Systematic Review and Meta-Analysis.

Objective: Traditional Chinese medicine (TCM) has a long history in the treatment of Immunoglobulin A nephropathy (IgAN). A large number of animal experiments focused on the TCM treatment of IgAN are conducted every year. The evidence for these preclinical studies is not clear. This study summarized and evaluated the results of animal experiments on TCM treatment for IgAN. Methods: We systematically searched animal studies from 6 databases from inception to August 30, 2022. We included Chinese studies from the key magazine of China technology. The quality of the included studies was evaluated with the SYRCLE animal experimental bias risk assessment tool and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results: Out of 832 records identified in the initial search, 30 studies were selected. The results indicated that, compared with the control group, the TCM treatment group improved 24 h urine protein (24 h-UP) level (standardized mean difference (SMD) 3.57, 95% confidence interval (CI) 4.48 to 2.66, P < 0.001), urine red blood cell (U-RBC) (SMD 13.66, 95% CI 17.99 to 9.32, P < 0.001), serum creatinine (Scr) (mean difference (MD) 10.89, 95% CI 17.00 to 4.77, P < 0.001), blood urea nitrogen (BUN) (MD 2.44, 95% CI 3.42 to 1.47, P < 0.001), tumor necrosis factor-α (TNF-α) (MD 171.28 to 95% CI 323.68 to 18.88, P=0.03), transforming growth factor-ß1 (TGF-ß) (SMD 4.02, 95% CI 7.26 to 0.77, P=0.02), matrix metalloproteinase-9/tissue inhibitors of metalloproteinase-1(MMP-9/TIMP-1) (MD 0.03, 95% CI 0.00 to 0.06, P=0.02), nephrin mRNA (SMD 3.39, 95% CI 2.59 to 4.18, P < 0.001). However, there is no difference in albumin level (MD 1.10, 95% CI 0.06 to 2.26, P=0.06) and interleukin-6 (IL-6) (MD 170.77, 95% CI 365.3 to 23.75, P=0.09). Conclusions: TCM can improve 24 h-UP, U-RBC, Scr, BUN, MMP-9/TIMP-1, TNF-α, TGF-ß, and nephrin mRNA of IgAN animal models. Moreover, there is a need for rigorous reporting of preclinical research methodology, which is essential to support the quality of preclinical research. Registration.
