The zebrafish model has attracted much attention due to its strong reproductive ability, short research cycle, and ease of maintenance. It has always been an important vertebrate model system, often used to carry out human disease research. Its motor behavior features have the advantages of being simpler, more intuitive, and quantifiable. In recent years, it has received widespread attention in the study of traditional Chinese medicine(TCM)for the treatment of sleep disorders, neurodegenerative diseases, fatigue, epilepsy, and other diseases. This paper reviews the characteristics of zebrafish motor behavior and its applications in the pharmacodynamic verification and mechanism research of TCM extracts, active ingredients, and TCM compounds, as well as in active ingredient screening and safety evaluation. The paper also analyzes its advantages and disadvantages, with the aim of improving the breadth and depth of zebrafish and its motor behavior applications in the field of TCM research.

OBJECTIVE: To investigate the effect of traditional Chinese Five-body balance exercise on patients with preserved ratio impaired spirometry (PRISm). METHODS: Fifteen patients with PRISm and 15 patients diagnosed with chronic obstructive pulmonary disease (COPD) were recruited from the Outpatient Department of Guang'anmen Hospital and Beijing Niujie Health Service Center from April to December, 2023. Participants in both groups attended supervised Five-body balance exercise training twice a week for 12 weeks. Patients with COPD continued their regular medication regimen during the intervention period. The endpoints were mean changes in the 6-min walk test (6MWT), St. George's Respiratory Questionnaire (SGRQ) score, cardiopulmonary exercise testing (CPET), pulmonary function, and scores of COPD assessment test (CAT), modified British Medical Research Council, Self-Rating Anxiety Scale, and Self-Rating Depression Scale from baseline to 12 weeks. Adverse events were monitored throughout the study. RESULTS: The PRISm group showed a significant improvement from baseline to week 12 in 6MWT, SGRQ symptom score, and forced vital capacity (FVC) compared to the COPD group (P<0.05). No significant between-group changes were observed in other outcome measurements (P>0.05). In addition, compared with baseline, both groups exhibited improvements in 6MWT, SGRQ score, and CPET at week 12 (P<0.05). The PRISm group also showed a significant increase in forced expiratory volume in 1 s and FVC, as well as a significant decrease in CAT score at week 12 (P<0.05). No adverse events were reported. CONCLUSION Patients with PRISm may benefit from Five-body balance exercise training, which can improve the exercise capacity, health-related quality of life, and lung function.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective To investigate the effect of smoking on the semen quality in infertile men.Methods A total of 360 male infertility patients were enrolled and divided into the smoking group(n=190)and non-smoking group(n=170)based on whether they smoked or not.Furthermore,the smoking group was subdivided into group A(≤10 sticks/d,n=63),group B(11～20 sticks/d,n=80),and group C(>20 sticks/d group,n=47)according to the amount of smoking.Semen volume,liquefaction time,sperm concentration,motility,DNA fragmentation rate and normal morphological rate were observed and compared between and within the groups.Results There were significant differences in semen volume,liquefaction time,sperm motility,normal morphological rate and DNA fragmentation rate between the smoking group and the non-smoking group(P<0.05).The semen volume,sperm motility and normal morphological rate of the smoking group were lower than those in the non-smoking group,and the DNA fragmentation rate and semen liquefaction time were higher than those in the non-smoking group.And with the increase of smoking volume,sperm motility and normal morphological rate decreased,semen liquefaction time and DNA fragmentation rate increased,and there was no significant difference in the sperm concentration between the smoking group and non-smoking group(P>0.05).There was no significant difference in the semen volume between the three groups with different smoking amounts(P>0.05).Conclusion Smoking has a negative impact on the sperm quality parameters such as semen volume,sperm motility,normal morphological rate,sperm motility,liquefaction time and DNA fragmentation,and the effect of heavy smoking is particularly obvious.We should strengthen the comprehensive health education,promote the healthy lifestyles and reduce smoking.

Objective To investigate clinical effect of tendons pulling,poking and kneading for the treatment of external humeral epicondylitis.Metods From January 2018 to December 2021,a multicenter randomized controlled study was per-formed to collect 192 patients with external humeral epicondylitis in Wangjing Hospital,Beijing Dianli Hospital,and Beijing Fengsheng Osteotraumatology Hospital,respectively,and they were divided into treatment group and control group by random number table method.There were 96 patients in treatment group,including 36 males and 60 females,aged from 28 to 60 years old with an average of(41.20±5.50)years old;the course of disease ranged from 1 to 14 days with an average of(5.24±1.35)days;they were treated once every other day for 2 weeks.There were 96 patients in control group,including 33 males and 63 females,aged from 26 to 60 years old with an average of(43.35±7.75)years old;the course of disease ranged from 1 to 14 days with an average of(5.86±1.48)days;they were treated with topical voltaalin combined with elbow joint fixation for 2 weeks.Visual analogue scale(VAS)and Hospital for Surgery Scoring System(HSS)elbow pronation and supination angles,wrist metacarpal flexion and dorsal extension angles,elbow tenderness between two groups were compared before treatment and at 1,3,5,7,11 and 13 days after treatment;Hospital for Surgery Scoring System 2(HSS2)was compared before treatment and the final treatment.Results All patients were followed up for 10 to 14 days with an average of(12±1.6)days.VAS between treatment group and control group before treatment were 6.83±1.36 and 6.79±1.58,respectively,and decreased to 1.49±1.09 and 2.11±1.81 after the final treatment.VAS of treatment group were significantly lower than those of control group at 1,3,5,7,9,11 and 13 days after treatment(P＜0.05).HSS between two groups were 61.73±11.00 and 36.47±12.45 before treatment,respectively,and increased to 94.42±5.9 and 91.44±9.11 at the final treatment.HSS of treatment group were signifi-cantly higher than those of control group at 1,3,5,7,9,11 and 13 days after treatment(P＜0.05).On the 5th day after treat-ment,the external and internal rotation angles of elbow in treatment group were(66.41±12.69)° and(66.35±13.54)°,while those in control group were(62.08±16.03)° and(61.77±16.35)°.On the 7th day after treatment,the external and internal ro-tation angles of elbow were(69.79±12.64)° and(70.02±13.55)° in treatment group,and(65.28±15.86)° and(65.09± 16.67)° in control group.Elbow joint motion in treatment group was higher than that in control group(P＜0.05).On the 5th day after treatment,angles of wrist dorsiflexion and palm flexion were(39.43±15.94)°and(46.68±11.10)° in treatment group,and(38.51±18.49)° and(44.27±13.58)° in control group.On the 7th day after treatment,angles of wrist dorsiflexion and palm flexion were(42.52±16.50)° and(49.23±10.96)° in treatment group,and(41.18±20.09)° and(46.64±14.63)° in control group.The motion of wrist joint in treatment group was higher than that in control group(P＜0.05).On the 13th day after treatment,HSS2 in treatment group 93.61±6.32 were higher than those in control group 92.06±7.94(P＜0.05).There was no significant difference in elbow tenderness between two groups at each time point(P＞0.05).Conclusion Voltaren external treatment combined with elbow fixation and tendons pulling,poking and kneading could effectively improve symptoms of exter-nal humeral epicondylitis.Compared with voltaren external treatment,tendons pulling,poking and kneading has advantages of longer analgesic time and better elbow function recovery.

Objective:To investigate the risk factors of decreased medication compliance of β-receptor blocker in patients with coronary heart disease(CHD)after percutaneous coronary intervention(PCI).Methods:A total of 160 CHD patients undergoing PCI from January 2020 to July 2021 in our hospital were selected.According to post-operative Morisky medication adherence scale(MMAS-8)score,they were divided into high compliance group(n=100,≥6 points)and low compliance group(n=60,＜6 points).Univariate and multivariate Logistic regression analysis were conducted to analyze the influencing factors of decreased medication compliance of β-receptor blocker in CHD patients after PCI.Results:The mean MMAS-8 score of 160 patients was(5.81±0.12)points.Com-pared with high compliance group,there were significant reductions in percentages of age＜60 years(74.00％vs.36.67％),high school or higher education(68.00％vs.40.00％),stent implanted duration＜2 years(54.00％vs.28.33％),family APGAR index score[(5.12±1.60)points vs.(4.52±2.10)points],proportion of APGAR score≥7 points(68.00％vs.33.33％),and significant rise in percentages of family income＜3000 RMB(34.00％vs.61.67％),self-paying(36.00％vs.60.00％),diabetes(47.00％vs.66.67％)and hypertension(42.00％vs.65.00％)in low compliance group,P＜0.05 or＜0.01.Multivariate Logistic regression analysis indicated that junior high school education,age ≥60 years,family income＜3000 RMB,self-paying,stent implanted duration≥2 years,hypertension and diabetes were independent risk factors for decreased medication compliance of β-re-ceptor blocker in CHD patients after PCI(OR=8.445～97725.056,P＜0.05 or＜0.01),while APGAR score ≥7 points was its independent protective factor(OR=0.005,P=0.001).Conclusion:The influencing factors for de-creased medication compliance of β-receptor blocker in CHD patients after PCI include age,stent implanted dura-tion,education level etc.It is necessary to focus on monitoring the medication of patients with risk factors and per-form intervention,which is helpful to improve medication compliance.

Objective To investigate the effect of vascular endothelial growth factor(VEGF)on the expression of genes related to ovarian steroid synthesis in mice and its underlying mechanism.Methods A transgenic mouse model with tetracycline-reversible regulation of VEGF expression was used,and the genotype of mice was identified by polymerase chain reaction(PCR).Twenty mice were divided into normal VEGF expression group(Dox+,n=10)and VEGF expression inhibition group(Dox-,n=10)by feeding them doxycycline.Western blotting was used to detect the expression of VEGF protein in ovarian tissues.Fluorescence quantitative PCR was used to detect the mRNA expression of VEGF,KDR and genes known to play roles in follicle development,such as follicle-stimulating hormone(FSH)and inhibin B(INHBB).HE staining was used to observe changes in ovarian tissue.Total RNA was extracted from mouse ovarian tissues for transcriptome sequencing,and the relevant differential genes were analyzed by FPKM and log2FC values.Results Compared with the Dox+group,the mRNA and protein levels of VEGF in the Dox-group significantly reduced,and the mRNA levels of KDR also significantly decreased(P<0.05).HE staining results showed that compared with the Dox+group,follicular development was impaired and atresia follicles appeared in the Dox-group.Sequencing analysis identified that significant differences in follicular development-related genes and steroid synthesis-related genes between the two groups(P<0.05).Enrichment analysis showed that VEGF in mouse ovaries mainly regulates ovarian steroidogenesis and other pathways.Fluorescence quantitative PCR results demonstrated that compared with the Dox+group,the follicular development-related genes(INHBB and FSHR)in the ovarian tissues of the Dox-group were significantly up-regulated(P<0.05),whereas the key genes of steroid synthesis(StAR,CYP11A1,3β-HSD)were significantly down-regulated(P<0.05).The quantitative results were basically consistent with the sequencing results.Conclusion Mice with inhibited VEGF exhibited ovarian follicular dysplasia,potentially due to the mechanism whereby VEGF inhibition downregulated the expression of genes associated with steroid synthesis,such as FSH and INHBB,thereby obstructing cholesterol metabolism.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To study the clinical and pathological characteristics,as well as diagnosis,treatment methods and prognosis of adult patients with chronic active Epstein-Barr virus infection(CAEBVI).Methods Clinical and pathological data of 8 adult patients with CAEBVI admitted to a hospital in Gansu Province from January 2017 to December 2022 were collected retrospectively,clinical and histopathological characteristics,EBV-related test re-sults,as well as treatment and prognosis of patients were analyzed.Results Among 8 CAEBVI patients,3 were males and 5 were females,with the median age of 21.5 years.The median time from onset to diagnosis of CAEBVI was 7 months.The main manifestations were fever,pancytopenia(involving two or three peripheral blood lines),as well as lymph node enlargement,hepatomegaly and splenomegaly.The quantifications of plasma EBV nucleic acid(DNA)were all＞1.0 × 103.The sorting results of EBV infected cells showed that 3 cases were T lymphocytes in-fection,2 were NK cell infection,and 3 were co-infection of T lymphocytes and NK cells.Bone marrow cytological examination of 8 patients showed no atypical lymphocytes,while 6 patients showed hemophagocytic cells.Flow cy-tometey(FCM)typing results showed that no abnormal cell population was detected in all the 8 patients,and no myeloid,B lymphocyte,T lymphocyte and NK cell markers were expressed.The positive rate of T cell receptor(TCR)gene rearrangement was 37.5％(n=3).Histopathology showed that most cases(n=6,75.0％)expressed CD3,partial cases expressed CD4,CD8,CD56,TIA-1,and EBV encoded RNA(EBER),all were positive.The survival rate of patients after treatment was 50.0％(n=4),the follow-up time was 6-51 months,the 1-year sur-vival rate was 85.7％,and the median survival time was 24 months.Conclusion CAEBVI is characterized by varia-ble clinical manifestations that may lead to fatal complications.Early diagnosis and individualized treatment should be performed to reduce mortality of patients.

AIM To investigate the effects and mechanism of Shenxiao Jiedu Tongluo Recipe on renal AIM 2-mediated pyroptosis of a golden hamster model of diabetic nephropathy(DN).METHODS Fifty male golden hamsters of SPF grade were randomly divided into the control group and the model group.The golden hamsters of the model group successfully developed into DN models by feeding of high glucose and high fat diet and intraperitoneal injection of STZ were further randomly assigned into the model group,the enagliflozin group(10 mg/kg),and the low-dose and the high-dose Shenxiao Jiedu Tongluo Recipe groups(12.8,25.6 g/kg)for 8 weeks gavage of the corresponding administration.The golden hamsters had their levels of fasting blood glucose,24 h-UTP,serum TC,LDL-C,Scr,and Sur detected by automatic biochemical analyzer;their serum SOD activity and MDA level detected by biochemical method;their serum levels of IL-1β,IL-18,and TNF-α detected by ELISA method;their pathomorphological changes of kidney tissue observed by HE and PAS staining;their protein expressions of ROS and γH2AX detected by immunofluorescence or immunohistochemistry;and their renal protein expressions of AIM 2,caspase-1 and GSDMD detected by Western blot and immunohistochemistry.RESULTS Compared with the control group,the model group showed atrophic glomeruli;enlarged glomerular capsule cavity;mesangial expansion;edema and necrosis in the dilated renal tubules;increased levels of fasting blood glucose,24 h-UTP,serum TC,LDL-C,Scr,Sur,IL-1β,IL-18,TNF-α,MDA and renal protein expressions of ROS,γH2AX,AIM2,caspase-1,GSDMD(P＜0.01);and decreased serum SOD activity(P＜0.01).Compared with the model group,the high-dose Shenxiao Jiedu Tongluo Recipe group and the enagliflozin group displayed improved renal histopathology,decreased levels of 24 h-UTP,serum TC,LDL-C,Scr,Sur,IL-1β,IL-18,TNF-α,MDA and renal protein expressions of ROS,γH2AX,AIM2,caspase-1,GSDMD(P＜0.05,P＜0.01);and increased serum SOD activity(P＜0.01).CONCLUSION Shenxiao Jiedu Tongluo Recipe can inhibit AIM 2-mediated cell death and alleviate renal inflammatory damage in golden hamsters by inhibiting their expression of ROS-dsDNA-AIM 2 signal pathway to attain reduction of their renal ROS level,DNA damage of renal intrinsic cells,and synthesis of AIM 2 inflammatory corpuscles as well.
