As a new type of model organism, zebrafish is gradually gaining prominence in the field of scientific research. The unique biological characteristics and advantages of zebrafish make them play an increasingly important role in the quality evaluation of traditional Chinese medicine. Compared with other common experimental animals, zebrafish have a fast reproductive and growth speed and high embryo transparency, making them an ideal model for evaluating the quality of traditional Chinese medicine. This provides a new perspective and method for research on traditional Chinese medicine. With the growing global interest in traditional Chinese medicine, it has become crucial to find scientific and accurate methods to evaluate the quality and effectiveness of traditional Chinese medicine. The introduction of the zebrafish model has brought new breakthroughs in the quality evaluation of traditional Chinese medicine. To further promote the application of zebrafish in evaluating the quality of traditional Chinese medicine, this article systematically searched and sorted out the previous studies related to the application of zebrafish for this purpose since 2023. The commonly used disease models and indicators of zebrafish in evaluating the effectiveness of traditional Chinese medicine, as well as the mechanism of zebrafish in exploring the active ingredients of traditional Chinese medicine, were primarily reviewed. The application of zebrafish in evaluating the safety of traditional Chinese medicine and the typical examples in ensuring the quality of traditional Chinese medicine were demonstrated. The limitations encountered by zebrafish models in evaluating the quality of traditional Chinese medicine were highlighted. The resolution of these problems will help further improve the accuracy and reliability of zebrafish in evaluating the quality of traditional Chinese medicine. The article discussed the evaluation of effectiveness, safety, and quality control of zebrafish applied in traditional Chinese medicine, so as to provide a reference for establishing standards for traditional Chinese medicine and promoting its modernization in the future.

ObjectiveBased on the zebrafish model, the hepatotoxicity and anti-osteoporotic activity of evodiamine (EVO) were studied. The mechanism of EVO in treating osteoporosis was explored by using network pharmacology and real-time polymerase chain reaction(Real-time PCR). MethodsThree days after fertilization (3 dpf), zebrafish were randomly selected and exposed to different concentrations of EVO solution for 96 hours. The mortality rate of zebrafish at different concentrations was calculated at the exposure endpoint, and a "dose-toxicity" curve was drawn. The 10% lethal concentration (LC10) was calculated. Liver phenotype, acridine orange staining, and pathological tissue sections of liver-transgenic zebrafish [CZ16 (gz15Tg.Tg (fabp 10a: ds Red; ela31: EGFP))] were used to confirm hepatotoxicity of EVO. On this basis, prednisolone was used to create a model of osteoporosis in zebrafish. The skull development, area of the skull stained by alizarin red, and cumulative optical density were used as indicators to evaluate the anti-osteoporotic activity of EVO in a safe dose. Based on network pharmacology, the mechanism of action of EVO in the treatment of osteoporosis was predicted and verified through Real-time PCR. ResultsThe LC10 of EVO on zebrafish (7 dpf) was determined to be 0.4 mg·L-1. Compared with the control group, sublethal concentrations (

[Objective] To analyze the prognostic value of prostate cancer (PCa) pyroptosis-related genes (PRGs) using gene expression databases and to explore the regulatory mechanism of nucleotidebinding oligomerization domain-like receptor containing pyrin domain 1 (NLRP1) in the pyroptosis of PCa cells. [Methods] Fragments per kilobase of exon model per million reads mapped (FPKM) data and clinical information from PCa and adjacent tissues from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) were obtained. Differentially expressed PRGs between PCa and adjacent tissues, classified subtypes and plotted survival curves were analyzed. Univariate Cox regression analysis, least absolute shrinkage and selection operator (LASSO) regression analysis were conducted to screen prognosis-related PRGs, risk scores were calculated, and a prognostic risk model was constructed and validated. Patients were divided into high and low risk groups based on the median risk scores from the training and validation sets, and gene ontology (GO) enrichment and kyoto encyclopedia of genes and genomes (KEGG) analysis were conducted on differentially expressed PRGs. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of NLRP1 in PCa cell lines, and pyroptosis was induced in DU145 and LNCaP cells while morphological changes were observed. Western blot (WB) was performed to detect the expression of pyroptosis-related molecules. [Results] A total of 6 prognostic-related PRGs were obtained, including CHMP4C, CYCS, GPX4, GSDMB, NLRP1, and PLCG1. The risk score was positively correlated with the risk of recurrence but negatively correlated with the progression-free survival (P<0.001). The area under the receiver operating characteristic curves (AUCs) for the training set at 1, 3, and 5 years were 0.769 (95%CI: 0.652-0.878), 0.804 (95%CI: 0.736-0.882), and 0.772 (95%CI: 0.631-0.905), respectively, while those for the validation set were 0.731 (95%CI: 0.647-0.826), 0.753 (95%CI: 0.674-0.818), and 0.763 (95%CI: 0.626-0.849), respectively. Differences in expression levels of the 6 PRGs were observed between the high and low risk groups in both the training and validation sets (P<0.05). Cox regression analysis showed that T stage, prostate specific antigen (PSA), Gleason grade, and risk score were independent predictors of PCa prognosis (P<0.05). Differences in risk scores were observed among patients of different ages, T stages, and Gleason grades (P<0.05). NLRP1 was found to be lowly expressed in PCa cell lines and was involved in the regulation of pyroptosis in DU145 and LNCaP cells. [Conclusion] The prognostic risk model constructed based on PRGs has a certain predictability for the prognosis of PCa patients, and NLRP1 may be involved in the regulation of pyroptosis in PCa cells.

Objective:To investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

OBJECTIVE To evaluate the efficacy and safety of apatinib combined with PD-1/PD-L1 inhibitors in the treatment of malignant solid tumors. METHODS Randomized controlled trials (RCTs) on apatinib combined with PD-1/PD-L1 inhibitors (combination group) versus monotherapy (apatinib or PD-1/PD-L1)combined with (or) chemotherapy/other treatments (control group) in the treatment of malignant solid tumors were collected from PubMed, Web of Science, Embase, Cochrane Library, CNKI, VIP, Wanfang Data and China Biomedical Literature Database. The search time limit was from the establishment of the databases to May 2025. After literature screening, data extraction and literature quality evaluation, meta-analysis was performed using RevMan 5.3 and Stata 14.0. RESULTS A total of 28 RCTs involving 2 974 patients were included. The objective response rate [RR=1.639, 95%CI(1.452,1.851), P<0.000 01], disease control rate [RR=1.284, 95%CI(1.178,1.399), P<0.000 01] and CD3+, CD4+, CD4+/CD8+ as well as the incidence of ADR such as hypertension, fatigue, proteinuria, thrombocytopenia were significantly higher in the combination group than control group (P<0.05 or P<0.000 01). The progressive disease rate [RR= 0.497, 95%CI(0.437, 0.566), P<0.000 01] and serum tumor + marker levels and CD8 were significantly lower in the combination group than control group (P<0.05 or P<0.000 01). Subgroup analysis results of different types of tumors showed that the objective response rate and disease control rate were significantly higher in the combination group than control group (P<0.05). The results of sensitivity analysis showed that the stability of this study was good. The results of publication bias analysis showed that there was a high possibility of publication bias in this study. CONCLUSIONS Apatinib combined with PD-1/ PD-L1 inhibitors has a significant efficacy in the treatment of different types of tumors, but attention should be paid to the occurrence of hypertension, fatigue, proteinuria and thrombocytopenia.

BACKGROUND:Studies have shown that there are significant differences in the geometric morphology of the distal femur of different races and genders,and there are more short female patients in southern China,so the phenomenon of overhanging or insufficient coverage of imported knee prostheses often occurs during surgery. OBJECTIVE:To investigate the characteristics of distal femur bones in southern Chinese women and compare them with imported joint prostheses by simulating the three-dimensional reconstruction of the distal femur bone and matching the femoral side after osteotomy with common imported joint prostheses. METHODS:From January to December 2021,120 female volunteers underwent a CT scan of knee joints.The images were imported into Mimics 20.0 software in Dicom format for three-dimensional reconstruction and then imported into Magic 22.0 software to simulate osteotomy by posterior cruciate ligament preserved total knee arthroplasty and to conduct a matching study with a normal imported joint prosthesis. RESULTS AND CONCLUSION:(1)The functional anteroposterior dimension(fAP)of the distal femur and Persona matched prosthesis had a total overhang rate of 25%(30/120).The fAP≤47 mm group had an overhang than the other groups(P<0.05).The poor coverage rate of Triathlon prosthesis was 12.5%(15/120),and poor coverage was more likely in fAP>53 mm group than in fAP≤53 mm group(P<0.05).(2)The total poor coverage rate of femoral intercondylar width matching with Triathlon prosthesis was 27.5%(33/120).Therefore,the poor coverage rate of bone surface in the central region of the distal femur was more likely in the fAP≤47 mm group than in other groups(P<0.05).The overhang rate of Journey II was 21.6%(26/120),and the overhang rate was higher in the fAP>53 mm group than in the fAP≤53 mm group(P<0.05).(3)Journey II CR prosthesis had the largest difference with the length of the anterior mediolateral diameter of the femur,which was easy to hang out on the anterolateral side of the femoral prosthesis.The Persona CR prosthesis has the largest difference with the length of the posterior mediolateral diameter of the femur,which is easy to be poorly covered in the posterior medial part of the prosthesis.It is recommended to increase the femoral prosthesis with reduced mediolateral diameter in the fAP≤47 mm group and add wider and narrower sizes than the conventional size of intercondylar width,and optimize the anterolateral angular arc design of the femoral prosthesis to improve the matching of posterior cruciate ligament reserved knee prosthesis.

ObjectiveBased on the nuclear factor erythroid 2 related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway, this paper explores the effect of Sinisan (SNS) on liver oxidative stress injury in cholestatic hepatitis rats and its mechanism. MethodThirty 6-week-old male SD rats were randomly divided into a control group, model group, low and high dose groups of SNS (2.5 and 5 g·kg-1) and ursodeoxycholic acid group (UDCA, 63 mg·kg-1), with six rats in each group. Rats were administrated for seven consecutive days. On the 5th day, the control group was given olive oil of 10 mL·kg-1, and the other groups were given alpha-naphthalene isothiocyanate (ANIT) of 80 mg·kg-1. The serum biochemical indicator levels of cholestasis and the content of antioxidant factors in rat liver were detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining was used to observe the pathological changes in liver tissue. The relative mRNA and protein expressions of Nrf2, HO-1, and quinone oxidoreductase 1 (NQO1) in liver tissue were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultCompared with the control group, the model group showed a significant increase in the serum biochemical indicator levels of cholestasis and the content of antioxidant factors in liver tissue (P<0.01). There were obvious pathological changes in the model group such as the disordered arrangement of hepatocytes, obvious congestion and necrosis in the portal area, infiltration of inflammatory cells, and destruction of the interlobular bile duct. The relative mRNA and protein expressions of Nrf2, HO-1, and NQO1 in liver tissue were significantly down-regulated in the model group (P<0.05, P<0.01). Compared with the model group, the groups of SNS showed a significant decrease in the serum biochemical indicator levels of cholestasis and the content of antioxidant factors in liver tissue (P<0.01), and the pathological liver injury was obviously improved. The necrotic area was reduced, and the infiltration of inflammatory cells was decreased. In addition, there was a small amount of extravasated blood in the interlobular vein. The relative mRNA and protein expressions of Nrf2, HO-1, and NQO1 in liver tissue were significantly up-regulated (P<0.05, P<0.01). ConclusionSNS can significantly improve liver injury in cholestatic hepatitis rats, and its mechanism may be related to the inhibition of oxidative stress response mediated by the Nrf2/HO-1 signaling pathway.

ObjectiveTo study the effect of Tanreqing injection (TRQ) on the pulmonary flora in the rat model of chronic obstructive pulmonary disease (COPD). MethodWistar rats were randomized into control, model, and TRQ groups. The rats in other groups except the control group were treated by smoking combined with intratracheal instillation of lipopolysaccharide for the modeling of COPD. The TRQ group was intraperitoneally injected with TRQ (2 g·kg-1). At the end of the experiment, after blood collection from the abdominal aorta of the rats, the lung tissue was collected for hematoxylin-eosin and picric sirius red staining to reveal the pathological changes. The lung lavage fluid was collected, and the diversity and relative abundance of lung flora in different groups were analyzed by 16S rDNA amplicon sequencing. ResultThe lungs of the control group were normal, and those of the model group showed neutrophil infiltration, telangiectasia, lung hemorrhage and emphysema in individual cases, and thickening of collagen fibers in the trachea. Compared with the model group, the TRQ group showed significantly improved lungs and recovered collagen fibers. The MLI analysis showed that compared with the control group, the model group showcased increased alveolar space (P<0.01), which was reduced in the TRQ group (P<0.05). Compared with the control group, the model group showed increased wall thickness (P<0.01), and the increase was attenuated in the TRQ group (P<0.01). TRQ increased the Simpson index and altered the α diversity of pulmonary flora. The results of principal co-ordinate analysis showed that TRQ changed the β diversity and reduced the β diversity index of pulmonary flora. At the genus level, the model group showed increased relative abundance of g_Bacillus and g_Brevundimonas and decreased relative abundance of g_Pseudomonas, compared with the control group. After treatment with TRQ, the relative abundance of g_Stenotrophomonas increased, and that of g_Bacillus decreased. The LEfSe of differential taxa between groups showed that the modeling increased the relative abundance of g_Lachnospiraceae_NK4A136_group, and TRQ treatment increased the relative abundance of g_Rhodococcus and g_Stenotrophomonas. ConclusionTRQ can regulate the diversity of pulmonary flora and restore the balance of bacterial genera in the rat model of COPD, which may be one of the mechanisms of the prevention and treatment of COPD with TRQ.
