ObjectiveTo investigate the effects of Simiaowan on intestinal barrier function and adenosine triphosphate (ATP) binding cassette transporter G2 (ABCG2) expression in hyperuricemic (HUA) rats, and elucidate its therapeutic mechanisms. MethodsForty male Sprague Dawley (SD) rats were randomized into a normal group, a model group, low-dose (282.6 mg·kg-1) and high-dose (565.2 mg·kg-1) Simiaowan groups, and a Benzbromarone (4.7 mg·kg-1) group. The HUA model was established via intraperitoneal injection of potassium oxonate (ip) combined with oral gavage of hypoxanthine (ig) for 14 days. Following modeling, treatments were administered for 14 days. Samples were collected and weighed 4 h after final dosing. Blood uric acid and hepatic function were analyzed. Histopathological changes were evaluated by hematoxylin-eosin (HE) staining, and Chiu's scoring was conducted. Enzyme-linked immunosorbent assay (ELISA) quantified tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), lipopolysaccharide (LPS), diamine oxidase (DAO), and D-lactic acid (D-LA) levels. Real-time polymerase chain reaction (Real-time PCR), Western blot, and immunohistochemistry assessed the expression of Claudin-1, Occludin, occludens-1 (ZO-1), and ABCG2 mRNAs and proteins. 16S rDNA amplicon sequencing characterized ileal microbiota. ResultsCompared with the normal group, the model group exhibited epithelial shedding in the ileal villus, structural disruption, infiltration of extensive inflammatory cells, and significantly elevated Chiu's scores (P<0.01). The DAO, TNF-α, IL-6, IL-1β, LPS, and D-LA levels in the ileum were markedly increased (P<0.01), while mRNA and protein expressions of Claudin 1, Occludin, ZO-1, and ABCG2, as well as positive staining area and proportion, were significantly reduced (P<0.01). Compared with the model group, the Simiaowan groups at all doses showed improved epithelial damage in the ileal villus, significantly lowered Chiu's scores (P<0.01), significantly reduced DAO, TNF-α, IL-6, IL-1β, LPS, and D-LA levels in the ileum (P<0.01), and upregulated mRNA and protein expressions of Claudin 1, Occludin, ZO-1, and ABCG2, as well as positive staining area and proportion (P<0.01). The 16S rDNA results showed that in the model group, the α-diversity index of the ileal microbiota was increased, and species diversity and richness were enhanced, with microbiota dysfunction observed. The community structure of the gut microbiota was significantly different from that of the normal microbiota. The abundance of probiotics was decreased, and the abundance of pathogenic bacteria was increased, with butyrate-producing bacteria showing a low abundance. In contrast, Simiaowan at all doses reduced species diversity and richness, regulated microbiota dysfunction, and promoted the shift of the structure of the gut microbiota community towards a normal one. This increased the abundance of beneficial bacteria, decreased the abundance of harmful bacteria, and restored the abundance of butyrate-producing bacteria. ConclusionSimiaowan enhances ileal uric acid excretion and further alleviates HUA by modulating the gut microbiota composition to improve the intestinal barrier and upregulate the expression of the urate transporter ABCG2 in HUA rats.

ObjectiveTo explore the quantity-quality transfer process of medicinal materials, decoction pieces and standard decoction of Haliotidis Concha(Haliotis discus hannai) by analyzing the physical phase and compositional changes, so as to provide references for the effective control of its quality. MethodsA total of 20 batches of Haliotidis Concha(H. discus hannai) from different habitats were collected and prepared into corresponding calcined products and standard decoction, and the content of CaCO3 of the three samples were determined and the extract yield and transfer rate of CaCO3 were calculated. The changes in elemental composition and their relative contents were investigated by X-ray fluorescence spectrometry(XRF), X-ray diffraction(XRD) was used to study the changes in the phase compositions of the three samples and to establish their respective XRD specific chromatogram. Fourier transform infrared spectrometry(FTIR) was used to study the changes in the chemical composition and content changes of the three samples and to establish their respective FTIR specific chromatogram, while combining hierarchical cluster analysis(HCA), principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) to find the common and differential characteristics, in order to explore the quantity-quality transfer relationship in the preparation process of standard decoction of Haliotidis Concha(H. discus hannai). ResultsThe CaCO3 contents of the 20 batches of medicinal materials, decoction pieces and standard decoction of Haliotidis Concha(H. discus hannai) were 93.87%-98.95%, 96.02%-99.97% and 38.29%-51.96%, respectively, and the extract yield of standard decoction was 1.71%-2.37%, and the CaCO3 transfer rate of decoction pieces-standard decoction was 0.68%-1.27%. XRF results showed that the elemental species and their relative contents contained in Haliotidis Concha and its calcined products had a high degree of similarity, and although there was no obvious difference in the elemental species contained in decoction pieces and standard decoction, the difference in the relative contents was obvious, which was mainly reflected in the decrease of the relative content of element Ca and the increase of the relative content of element Na. XRD results showed that Haliotidis Concha mainly contained CaCO3 of aragonite and calcite, while calcined Haliotidis Concha only contained CaCO3 of calcite, and standard decoction mainly contained CaCO3 of calcite and Na2CO3 of natrite. FTIR results showed that there were internal vibrations of O-H, C-H, C=O, HCO3- and CO32- groups in Haliotidis Concha, while O-H, HCO3- and CO32- groups existed in the calcined products and standard decoction. ConclusionThe changes of Haliotidis Concha and calcined Haliotidis Concha are mainly the increase of CaCO3 content, the transformation of CaCO3 aragonite crystal form to calcite crystal form and the absence of organic components after calcination, and the changes of calcined products and standard decoction are mainly the decrease of CaCO3 content and the increase of Na2CO3 relative content. The method established in the study is applicable to the quality control of the shellfish medicines-decoction pieces- standard decoction, which provides a new idea for the study of quality control of dispensing granules of shellfish medicines.

OBJECTIVE To systematically evaluate the efficacy and safety of tislelizumab in the treatment of advanced non- small cell lung cancer (NSCLC). METHODS Computerized searches were conducted in PubMed, Embase, the Cochrane Library, CNKI, Wanfang and other Chinese and English databases to collect randomized controlled trials (RCTs) on tislelizumab for advanced NSCLC. The search period was from the establishment of the databases to December 2024. After strictly screening the literature, extracting data and conducting quality evaluations in accordance with the inclusion and exclusion criteria, a meta-analysis was performed using RevMan 5.3 and Stata 16.0 software. RESULTS A total of 18 RCTs involving 2 337 patients were included, with 1 283 in the experimental group and 1 054 in the control group. The meta-analysis results showed that the objective response rate [RR=1.61, 95%CI (1.48, 1.75), P<0.000 01], disease control rate [RR=1.21, 95%CI (1.13, 1.29), P<0.000 01], progression free survival [HR=0.55, 95%CI (0.45, 0.66), P<0.000 01], and overall survival [HR=0.78, 95%CI(0.62, 0.97), P=0.03] were significantly better in the experimental group than in the control group. There was no statistically significant difference in the incidence of adverse reactions between the two groups [RR=1.00, 95%CI (0.73, 1.37), P=1.00]; among the common adverse reactions, only the incidence of liver function impairment was significantly higher in the experimental group than in the control group [RR=1.30, 95%CI (1.10, 1.54), P<0.01]. CONCLUSIONS Tislelizumab in combination with chemotherapy or targeted drugs significantly improves the efficacy in patients with advanced NSCLC without increasing the risk of adverse reactions overall. However, liver function should be closely monitored during treatment.

Hypertension is a major risk factor for cardiovascular diseases. Controlling blood pressure can reduce the incidence of cardiovascular events and mortality. The patients with hypertension are mainly treated with antihypertensive drugs. For the patients who can't achieve the target blood pressure with a single drug, comprehensive treatment strategies become particularly important. Chinese patent medicines are prepared by modern extraction and processing technology based on the basic theory of traditional Chinese medicine(TCM). Due to the stable antihypertensive effect, target organ protection, and synergistic effect with western medicine, Chinese patent medicines are becoming one of the effective options for the treatment of hypertension. At present, there are many systematic reviews on the treatment of hypertension with Chinese patent medicines, which makes it difficult for health policy makers and health service providers to choose the best evidence for the treatment. Umbrella review can integrate multiple systematic reviews to comprehensively assess the quality of evidence and potential bias, thereby providing high-quality evidence-based medicine basis for formulating clinical guidelines and optimizing treatment strategies. In this study, the systematic reviews/Meta-analysis of Chinese patent medicines in the treatment of essential hypertension were systematically searched. Sixty-nine articles were included for the umbrella review. Literature information was extracted, and the corrected covered area(CCA) was calculated to quantitatively evaluate the overlap degree of original studies in systematic reviews/Meta-analysis. The risk of bias in systematic reviews(ROBIS) tool and Cochrane RoB tool 2.0 were used to assess the risk of bias of the included studies. A Measure Tool to Assess Systematic Reviews 2(AMSTAR 2) was used to evaluate the methodological quality of systematic reviews/Meta-analysis. The quality of evidence was evaluated based on the Grade of Recommendations Assessment, Development and Evaluation(GRADE). The results showed that the Chinese patent medicines in the categories of treating wind, resolving stasis, and reinforcing healthy Qi were effective in lowering blood pressure. The Chinese patent medicines for resolving stasis combined with conventional treatment can lower blood pressure and the levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglyceride, and total cholesterol in the treatment of hypertension complicated with coronary heart disease and hypertension complicated with left ventricular hypertrophy. Moreover, the combined therapy can recover the interventricular septal thickness, left ventricular posterior wall thickness, left ventricular mass index, left ventricular end diastolic diameter, and left ventricular ejection fraction in the case of left ventricular hypertrophy. The Chinese patent medicines for resolving stasis and for replenishing Qi and restoring pulse can be used in combination with conventional treatment for hypertension complicated with arrhythmia, which can lower blood pressure while improving the outcome indicators such as the P-wave dispersion of arrhythmia, left atrial diameter, ejection fraction, heart rate, and recurrence time. Due to the heterogeneity, the efficacy evidence obtained by the umbrella review needs to be further verified through precise clinical studies and long-term follow-up.

Diabetic peripheral neuropathy(DPN) is a neurodegenerative disease of diabetes mellitus involving peripheral nervous system damage, which is characterized by axonal degenerative necrosis, Schwann cell apoptosis and demyelination of nerve myelin sheath as the main pathological features, this disease is highly prevalent and is a major cause of disability in diabetic patients. Currently, the pathogenesis of DPN may be related to oxidative stress, inflammatory response, metabolic abnormality, and microcirculation disorder. The treatment of DPN in modern medicine mainly starts from controlling blood glucose, nourishing nerves and improving microcirculation, which can only alleviate the clinical symptoms of patients, and it is difficult to fundamentally improve the pathological damage of peripheral nerves. Mitochondrial quality control refers to the physiological mechanisms that can maintain the morphology and functional homeostasis of mitochondria, including mitochondrial biogenesis, mitochondrial dynamics, mitochondrial oxidative stress and mitochondrial autophagy, and abnormal changes of which may cause damage to peripheral nerves. After reviewing the literature, it was found that traditional Chinese medicine(TCM) can improve the low level of mitochondrial biogenesis in DPN, maintain the balance of mitochondrial dynamics, inhibit mitochondrial oxidative stress and mitochondrial autophagy, and delay apoptosis of Schwann cells and neural axon damage, which has obvious effects on the treatment of DPN. With the deepening of research, mitochondrial quality control may become one of the potential targets for the research of new anti-DPN drugs, therefore, this paper summarized the research progress of TCM in treating DPN based on four aspects of mitochondrial quality control, with the aim of providing a theoretical research basis for the discovery of new drugs.
