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.

ObjectiveTo study the mechanism of matrine in the treatment of inflammatory bowel disease （IBD） based on the zebrafish model and network pharmacology. MethodThe IBD model of zebrafish was established using 2，4，6-trinitro-benzenesulfonicacid （TNBS）， and the intestinal phagocytic function， goblet cell secretion， and neutrophil aggregation were evaluated using neutral red staining， alcian blue staining， and neutrophil number changes. Changes in tumor necrosis factor （TNF）-α and cholecystokinin （CCK） content in zebrafish were determined by using relevant reagent kits. Network pharmacology and molecular docking techniques were used to predict the potential mechanism of matrine in the treatment of IBD. Gene expression of relevant targets was verified through Real-time polymerase chain reaction （Real-time PCR）. ResultCompared with the model group， the matrine administration group can increase the neutral red staining area in a dose-dependent manner and improve intestinal phagocytic function（P<0.05，P<0.01）. It can reduce the staining area of alcian blue and affect the secretion of intestinal goblet cells（P<0.01）. It can reduce the number of neutrophil granulocytes， relieve its aggregation， significantly reduce TNF-α content（P<0.01）， and increase the CCK content. Network pharmacology analysis identifies 28 potential targets for matrine in the treatment of IBD. The top five targets by protein-protein interaction （PPI） network analysis are CHRNA7， DRD1， CHRNA4， SLC6A3， and GRM5. The Kyoto encyclopedia of genes and genomes （KEGG） results show that the treatment of IBD with matrine may be related to neuroactive ligand-receptor interaction， cholinergic synapse， and neutrophil extracellular trap formation. Real-time PCR results show that matrine can affect the expression level of related target genes. Conclusionmatrine has a certain therapeutic effect on IBD and can affect the inflammatory response of IBD. Its therapeutic effect may be related to neuroactive ligand-receptor interaction and other pathways.

Polyphyllin Ⅰ(PPⅠ)and polyphyllin Ⅱ(PⅡ)are the main active substances in the Paris polyphylla.However,liver toxicity of these compounds has impeded their clinical application and the potential hepatotoxicity mechanisms remain to be elucidated.In this work,we found that PPⅠ and PⅡ exposure could induce significant hepatotoxicity in human liver cell line L-02 and zebrafish in a dose-dependent manner.The results of the proteomic analysis in L-02 cells and transcriptome in zebrafish indicated that the hepa-totoxicity of PPⅡ and PⅡwas associated with the cholesterol biosynthetic pathway disorders,which were alleviated by the cholesterol biosynthesis inhibitor lovastatin.Additionally,3-hydroxy-3-methy-lglutaryl CoA reductase(HMGCR)and squalene epoxidase(SQLE),the two rate-limiting enzymes in the choles-terol synthesis,selected as the potential targets,were confirmed by the molecular docking,the over-expression,and knockdown of HMGCR or SQLE with siRNA.Finally,the pull-down and surface plasmon resonance technology revealed that PPⅠ could directly bind with SQLE but not with HMGCR.Collectively,these data demonstrated that PPⅠ-induced hepatotoxicity resulted from the direct binding with SQLE protein and impaired the sterol-regulatory element binding protein 2/HMGCR/SQLE/lanosterol synthase pathways,thus disturbing the cholesterol biosynthesis pathway.The findings of this research can contribute to a better understanding of the key role of SQLE as a potential target in drug-induced hepatotoxicity and provide a therapeutic strategy for the prevention of drug toxic effects with similar structures in the future.

Objective To investigate the current status of application of resources on medical exposure in Dongying, China, and to provide fundamental data for setting up the health information management system of occupational radiation diseases and implementing health supervision and management strategies. Methods According to the requirements of monitoring program on radiation health of Dongying in 2021, a general survey was carried out in all medical institutions (other than dental clinics) providing radiodiagnosis and radiotherapy services by the field investigation method using the unified questionnaires and survey content, and a descriptive analysis was conducted on the results. Results There were 92 institutions of radiodiagnosis and radiotherapy in Dongying, 1112 radiation workers who accounted for 5.9% of all workers on duty, including 679 (61.1%) males and 433 (38.9%) females, and 364 pieces of radiation equipment, including 339 for X-ray diagnosis, 8 for radiotherapy, 2 for nuclear medicine, and 15 for interventional radiology. The allocation of personal protective equipment for interventional radiology staff in tertiary hospitals was higher than that in secondary hospitals, in which there were 0.36 and 0.23 pieces of lead-rubber aprons, 0.43 and 0.30 pieces of lead-rubber hats, 0.50 and 0.35 pieces of lead-rubber collars, 0.05 and 0 pairs of lead-rubber gloves, and 0.31 and 0.17 pairs of lead protection glasses per capita, respectively. The allocation rates of lead-rubber collars and lead protection glasses in the nuclear medicine staff were higher than those in the interventional radiology staff, with 0.63 collars and 0.88 pairs per capita, respectively. The annual frequency of medical exposure was calculated to be 864.3 person-times per 1000 population for radiodiagnosis and 5.2 patients per 1000 population for radiotherapy. Conclusion The allocation and application of resources on medical exposure in Dongying is unbalanced, so it is demanded to set up a health information management system of occupational radiation diseases for continuously mastering the application of medical exposure and adopting differentiated regulatory measures such as rating classification in Dongying.

BACKGROUND: The onset and clinical presentation of systemic lupus erythematosus (SLE) are sex-related. Few studies have investigated the distinctions in clinical characteristics and treatment preferences in male and female SLE patients in the initial cohort. This study aimed to improve the understanding of Chinese SLE patients by characterizing the different sexes of SLE patients in the inception cohort. METHODS: Based on the initial patient cohort established by the Chinese SLE Treatment and Research Group, a total of 8713 patients (795 men and 7918 women) with newly diagnosed SLE were enrolled between April 2009 and March 2021. Of these, 2900 patients (347 men and 2553 women) were eligible for lupus nephritis (LN). A cross-sectional analysis of the baseline demographic characteristics, clinical manifestations, laboratory parameters, organ damage, initial treatment regimens, and renal pathology classification was performed according to sex. RESULTS: In the SLE group, as compared to female patients, male patients had a later age of onset (male vs. female: 37.0 ± 15.8 years vs. 35.1 ± 13.7 years, P  = 0.006) and a higher SLE International Collaborative Clinic/American College of Rheumatology damage index score (male vs. female: 0.47 ± 1.13 vs. 0.34 ± 0.81, P  = 0.015), LN (male vs. female: 43.6% vs. 32.2%, P < 0.001), fever (male vs. female: 18.0% vs. 14.6%, P  = 0.010), thrombocytopenia (male vs. female: 21.4% vs. 18.5%, P  = 0.050), serositis (male vs. female: 14.7% vs. 11.7%, P  = 0.013), renal damage (male vs. female: 11.1% vs. 7.4%, P < 0.001), and treatment with cyclophosphamide (CYC) (P < 0.001). The frequency of leukopenia (male vs. female: 20.5% vs. 25.4%, P  = 0.002) and arthritis (male vs. female: 22.0% vs. 29.9%, P < 0.001) was less in male patients with SLE. In LN, no differences were observed in disease duration, SLE Disease Activity Index score, renal biopsy pathological typing, or 24-h urine protein quantification among the sexes. In comparisons with female patients with LN, male patients had later onset ages (P  = 0.026), high serum creatinine (P < 0.001), higher end-stage renal failure rates (P  = 0.002), musculoskeletal damage (P  = 0.023), cardiovascular impairment (P  = 0.009), and CYC use (P  = 0.001); while leukopenia (P  = 0.017), arthritis (P  = 0.014), and mycophenolate usage (P  = 0.013) rates were lower. CONCLUSIONS Male SLE patients had more severe organ damage and a higher LN incidence compared with female SLE patients; therefore, they may require more aggressive initial treatment compared to female patients.

Objective: To explore the relationship between screen time and prediabetes in adolescents. Methods: A cross-section study. A total of 532 adolescents aged 12~18 years in Shandong Zibo Vocational Institute were selected by stratified sampling method. The screen time was investigated by questionnaire survey. Measuring fasting fingertip blood glucose, screening for who with potentially abnormal blood glucose, and measuring their fasting venous blood glucose, which is to determine whether it is prediabetes. Results: With the increase of screen time, the risk of prediabetes increased continuously. Compared with adolescents with those who spend 0~119 minute per day screen time, the risk of prediabetes of adolescents with an average daily screen time of 120~239, 240~317, ≥318 minute increased by 0.37%, 2.63%, and 3.57%, respectively. After multi-factor adjustment, the risk of prediabetes with who take 240~317, ≥318 minute per day screen time is still higher than who with the average daily screen time of 0~119 minute, the adjusted OR was 2.502 (95% CI 1.279-4.897), 2.337(95% CI=1.189-4.594). Conclusion The results of this study show that the longer the screen time, the higher the risk of prediabetes in adolescents, and adolescents should be encouraged to reduce screen time.

Objective To elucidate the effect of cognitive functions on medication compliance of schizophrenia patients at stable phase, and provide clinical cognitive coping strategies to improve the medication compliance of schizophrenia patients. Methods Two hundred and thirty-eight schizophrenia patients at stable phase, admitted to psychiatry department of the 3rd affiliated hospital of Sun Yat-sen University from May 2017 to October 2017, and all study subjects were divided into without medication compliance group (the scores of medication compliance scale≤4, n=32) and medication compliance group (the scores of medication compliance scale>4, n=206) by Medication Adherence Rating Scale (MARS). MATRICS Consensus Cognitive Battery (MCCB) and Brief Psychiatric Rating Scale (BPRS) were used to evaluate the differences of cognitive performance and disease severity between groups. The factors influencing medication compliance of schizophrenia patients with stable phase were explored by multiple linear regression analysis. Results (1) The total scores of MCCB and it,s subscales scores (except for visual learning) of schizophrenia patients with medication compliance were higher than that of patients without medication compliance. The scores of symbol coding, spatial span and emotional intelligence ability in medication compliance group were significantly higher than those of patients without medication compliance (P<0.05). (2) Symbol coding (neurocognition ability), emotion management (social cognition ability), severity of illness, and antipsychotic drug dose were the independent influencing factors of medication compliance of schizophrenia patients with stable phase (P<0.05). Conclusion The medication compliance of schizophrenia patients with stable phase is not only affected by antipsychotics dose and severity of illness, but also affected by neurocognitive and social cognitive functions.

Objective To evaluate the clinical performance of chemiluminescent immunoassay (CLIA) on anti-nuclear antibody(ANA) specific autoantibodies testing.Methods A multi-center clinical study A total of 811 Sera samples were collected from 6 collaborating hospitals during the period of April to July 2016, and tested with CLIA and line immunoassay (LIA) in parallel for autoantibodies to ribonucleoprotein(RNP), smith antigen(Sm), SSA/Ro60,SSB/La, centromere protein B(CENPB), double-stranded DNA(dsDNA), nucleosome(Nuc), and ribosome P protein(Rib-P).The positive rate,specificity and qualitative coincidence rate for each antibody between CLIA and LIA methods were analyzed.All discrepant samples for systemic lupus erythematosus (SLE) highly specific autoantibodies (including anti-Sm, dsDNA, Nuc and Rib-P) were retested by enzyme linked immunosorbent assay (ELISA) and further analyzed with SLE disease cohort using McNemar test.Results The positive rate and specificity of CLIA and LIA for antibodies to ANA specific antigens were comparable.Excellent qualitative coincidence were found between CLIA and LIA for the detection of anti-RNP, SSA/Ro60, SSB/La and CENPB (Kappa>0.75), while the coincidence rate foranti-Sm, dsDNA, Nuc and Rib-P detection were moderate (0.4

OBJECTIVEThis study investigated the expression of BNIP3 in salivary adenoid cystic carcinoma (SACC) and its correlations to the clinicopathological features and prognosis of patients with SACC. The role of BNIP3 in the progress of hypoxia-induced autophagy was elucidated.

METHODSThe expression levels of BNIP3, hypoxia inducible factor (HIF)-1α, and LC3 in 65 SACC cases were detected by immunohistochemical staining method, and the correlation between the expression of BNIP3 and the clinicopathological features in SACC was analyzed. In addition, the correlations of BNIP3 gene expression with HIF-1α and LC3 gene expression were analyzed. The survival rate of patients with SACC was evaluated by univa-riate survival analysis.

RESULTSBNIP3 was considerably expressed in SACC in all three histological patterns, and was positive in 41 cases (63.1%). BNIP3 gene expression was significantly correlated with histological grade (P=0.001) and HIF-1α gene expression (P=0.011). By contrast, BNIP3 gene expression was not significantly correlated with LC3 gene expression (P=
0.167). The overall survival rate of patients with negative BNIP3 expression was better than that of patients with positive BNIP3 expression (P<0.05).

CONCLUSIONSBNIP3 might play a vital role in the tumorigenesis of SACC and may be a new target for gene therapy.

ObjectiveTo investigate the correlation between procalcitonin (PCT), C-reactive protein (CRP) and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score, and to investigate the value in assessment of PCT and CRP in prognosis in patients with sepsis.Methods Clinical data of patients admitted to intensive care unit (ICU) of Changzheng Hospital Affiliated to the Second Military Medical University from January 2011 to June 2014 were retrospectively analyzed. 201 sepsis patients who received PCT and CRP tests, and evaluation of APACHEⅡ score and SOFA score were enrolled. The values of PCT, CRP, APACHEⅡ score and SOFA score between survivals (n = 136) and non-survivals (n = 65) were compared. The values of PCT and CRP among groups with different APACHEⅡ scores and SOFA scores were compared. The relationships between PCT, CRP and APACHEⅡ score and SOFA score were analyzed by Spearman correlation analysis. Receiver operating characteristic (ROC) curve was plotted to assess the prognostic value of PCT and CRP for prognosis of patients with sepsis.Results Compared with survival group, the values of PCT [μg/L: 11.03 (19.17) vs. 1.39 (2.61), Z= -4.572,P< 0.001], APACHEⅡ score (19.16±5.32 vs. 10.01±3.88,t = -13.807,P< 0.001) and SOFA score (9.66±4.28 vs. 4.27±3.19,t = -9.993,P< 0.001) in non-survival group were significantly increased, but the value of CRP was not significantly different between non-survival group and survival group [mg/L: 75.22 (110.94) vs. 56.93 (100.75),Z = -0.731,P = 0.665]. The values of PCT were significantly correlated with APACHEⅡ score and SOFA score (r1 = 0.373,r2 = 0.392, bothP< 0.001), but the values of CRP were not significantly correlated with APACHEⅡscore and SOFA score (r1 = -0.073,P1 = 0.411;r2 = -0.106,P2 = 0.282). The values of PCT rose significantly as the APACHEⅡ score and SOFA score became higher, but the value of CRP was not significantly increased. When APACHEⅡ score was 0-10, 11-20, and> 20, the value of PCT was 1.45 (2.62), 1.96 (9.04), and 7.41 (28.9)μg/L, respectively, and the value of CRP was 57.50 (83.40), 59.00 (119.70), and 77.60 (120.00) mg/L, respectively. When SOFA score was 0-5, 6-10, and> 10, the value of PCT was respectively 1.43 (3.09), 3.41 (9.75), and 5.43 (29.60)μg/L, and the value of CRP was 49.30 (86.20), 76.00 (108.70), and 75.60 (118.10) mg/L, respectively. There was significant difference in PCT between any two groups with different APACHEⅡ and SOFA scores (P< 0.05 orP<0.01), but no significant differences in CRP were found. The area under the ROC curve (AUC) of PCT for prognosis was significantly greater than that of CRP [0.872 (95% confidence interval 0.811-0.943) vs. 0.512 (95% confidence interval 0.427-0.612),P< 0.001]. When the cut-off value of PCT was 3.36μg/L, the sensitivity was 66.8%, and the specificity was 45.4%. When the cut-off value of CRP was 44.50 mg/L, the sensitivity was 82.2%, and the specificity was 80.3%.Conclusions Compared with CRP, PCT was more significantly correlated with APACHEⅡ score and SOFA score. PCT can be a better indicator for evaluation of degree of severity, and also prognosis in sepsis patients.
