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 variability of bone metabolism levels among different populations and its association with knee osteoarthritis (KOA) pain. METHODS: A total of 50 people (control group) who participated in physical examination from January 2023 to June 2023 were selected, including 26 males and 24 females, wtih a mean aged of (52.14±9.04) years old ranging 41 to 65 years old. The other 50 patients with knee osteoarthritis(case group) who attended the outpatient clinic of the Orthopedics and Traumatology Department in the same time period, including 19 males and 31 females, with a mean age of (53.60±7.76) years old ranging 40 to 65 years. The two groups of Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC) and bone metabolism markers, such as 25-hydroxy-cholecalciferol[25(OH)D], β-isomerized typeⅠcollagen C-telopeptide breakdown products (β-CTX), total typeⅠprocollagen N-terminal propeptide (t-PINP), osteocalcin (OC), parathormone (PTH) levels were compared. Pearson correlation analysis was used to compare the correlation between two groups of bone metabolism related markers and WOMAC. RESULTS: The WOMAC score of the case group (39.90±2.34) was higher than that of the control group (3.60±0.57), with significant difference (P<0.05). There was no significant difference between the two groups of 25 (OH)D, β-CTX and PTH (P>0.05). The t-PINP and OC of the case group were (62.90±52.40) and (19.88±10.15) ng·ml-1, respectively, and those of the control group were (38.86±10.82) and (14.90±3.62) ng·ml^-1, respectively;the t-PINP and OC of the case group were higher than those of the control group, with significant difference (P<0.05). Pearson correlation analysis showed that t-PINP was positively correlated with WOMAC pain score in the case group (r²=0.045, P<0.01). CONCLUSION Bone metabolism levels in the serum of patients with knee osteoarthritis are different from those of healthy people, and the difference between OC and t-PINP is the most obvious, and the concentration of t-PINP levels is positively correlated with pain symptoms in patients with KOA. However, the specific mechanism of correlation between the bone metabolism levels of patients with KOA and their pain symptoms needs to be further elucidated by basic experimental research as well as by enlarging the samples.

Purpose::The reconstruction of Allen's type IV fingertip amputation is a clinical challenge. Our team designed bilateral unequal-sized hallux osteo-onychocutaneous free flaps for the long-term reconstruction of Allen's type IV fingertip amputation and conducted a retrospective study with a 5-year follow-up aims to evaluate the effects of this technique.Methods::A retrospective analysis with a 5-year follow-up including 13 patients with Allen's type IV fingertip amputation who were admitted to our hospital from January 2010 to January 2017 was conducted. The patients were treated with bilateral unequal-sized hallux osteo-onychocutaneous free flaps. The operation time, intraoperative blood loss, and complications were recorded, and the survival rate of the transplanted flaps was calculated. During the 5-year follow-up after operation, the nail growth time was recorded and the finger appearance was observed. At the last follow-up appointment, the length, width, and girth of the reconstructed fingertip and contralateral normal fingertip, range of motion of the reconstructed fingertip and contralateral normal fingertip, Semmes-Weinstein test (for the evaluation of tactile sensation), and two-point discrimination testing results were recorded. SPSS 22.0 software was used for the statistical analysis and the data are presented as mean ± SD.Results::The mean operation time was (5.62 ± 0.51) h, the mean intraoperative blood loss was (34.15 ± 3.13) mL, and the survival rate of the transplanted flaps was 100%. During the 5-year follow-up, the average nail growth time was (10.14 ± 1.98) months and the average bone union time was (3.78 ± 0.91) months. The length, width, and girth of the reconstructed fingertip were (31.52 ± 3.73) mm, (17.82 ± 1.74) mm, and (59.75 ± 3.04) mm, respectively, which did not differ from those of the contralateral normal fingertip. The range of motion of the reconstructed fingertip was (12.15 ± 2.79) degrees which is different from that of the contralateral normal fingertip. The average tactile sensation evaluated via the Semmes-Weinstein test and the average two-point discrimination test of the reconstructed fingertip were (0.39 ± 0.17) g and (7.46 ± 1.14) mm, respectively, which were not different from those of the contralateral normal fingertip. The average Maryland score of feet in the donor area was 87.66 ± 7.39, which was satisfactory.Conclusion::Bilateral unequal-sized hallux osteo-onychocutaneous free flaps are an effective method to reconstruct Allen's type IV fingertip amputations with a satisfactory appearance and good sensory function.

Objective To investigate the effect of early postoperative abnormal blood glucose on the short-term prognosis of non-small cell lung cancer(NSCLC),and to analyze the clinical characteristics and risk factors related to poor early prognosis.Methods A total of 897 patients with NSCLC who underwent thoracoscopic surgery in Huadong Hospital,Fudan University from Jan 2020 to Aug 2021 were divided into hyperglycemia(HG)group(>7.8 mmol/L)and normal blood glucose(NG)group(≤7.8 mmol/L and≥3.9 mmol/L)according to the early postoperative blood glucose values.Additionally,the patients were divided into higher blood glucose fluctuation group(≥4 mmol/L)and the group with lower blood glucose fluctuation(<4 mmol/L)basing on the fasting blood glucose.Using Logistic regression models,column line charts,ROC curves and other methods,we aimed to clarify the impact of early postoperative blood glucose abnormalities on short-term prognosis,explore clinical characteristics associated with poor short-term outcomes,identify other high-risk factors,and establish relevant risk prediction models.Results Compared with the NG group,the incidence of postoperative pneumonia,thromboembolism,ICU admission rate,total length of hospital stay and hospital cost were significantly higher in the HG group(P<0.05).Higher blood glucose fluctuation group had a greater risk of ICU admission(P=0.003).Logistic regression analysis showed that age,preoperative fasting glucose,white blood cell count and cytokeratin 19 fragment antigen 21-1(CYFRA21-1)were risk factors for postoperative hyperglycemia(P<0.05).Contrary to the effect of BMI,diabetes,male patients,higher blood glucose fluctuation,white blood cell count and age were the risk factors for postoperative adverse events(P<0.05).The AUC of the column line chart model was 0.661(95%CI:0.624-0.698),indicating good discriminative ability for predicting poor short-term prognosis postoperatively.Calibration curves also demonstrated good consistency between predicted and actual probabilities.Conclusion Early postoperative blood glucose fluctuations independently impact the short-term prognosis of thoracoscopic NSCLC patients.Blood glucose combined with gender,BMI,white blood cell count,age and diabetes history can serve as predictive factors for poor short-term prognosis postoperatively.Additionally,a column line chart constructed based on these factors may aid clinicians in early intervention for NSCLC patients with indications.

Objective To clarify the mechanism that HIV infection mediates mitochondrial damage of CD4⁺ T lymphocytes (CD4⁺ T cells) through mitogen-activated protein kinase (MAPK) pathway. Methods From October 1st, 2022 to March 31st, 2023, 47 HIV-infected people who received antiretroviral therapy (ART) for 4 years were recruited, including 22 immune non-responders (INR) and 25 responders (IR); and 26 sex and age-matched control participants (HC) who were negative for HCV, HBV, and HIV infections. The immune parameters were analyzed by flow cytometry. Finally, peripheral blood mononuclear cells (PBMCs) from HC or HIV patients were treated with MAPK pathway inhibitor SB203580, and the changes of mitochondrial function of CD4⁺ T cells were observed. Results Compared with HC group, the proportion of CD4⁺ T cells in PBMCs in INR group and IR group was significantly lower, and the proportion of CD4⁺ T cells in PBMCs in INR group was significantly lower than that in IR group. In addition, the proportion of naive (CD45RA⁺CD27⁺)T cells in PBMCs in INR group was significantly lower than that in HC group and IR group. Compared with HC group and IR group, the proportions of CD4⁺PD-1⁺, CD4⁺Av⁺ and CD4⁺MO⁺ in PBMCs in INR group and the proportions of CD45RA⁺CD27⁺PD-1⁺, CD45RA⁺CD27⁺Av⁺, CD45RA⁺CD27⁺MO⁺ in CD4⁺ T cell subsets increased significant. Compared with HC-con group, the basal respiration, maximal respiration and adenosine triphosphate(ATP) production of CD4⁺ T cells in HIV-con group decreased significantly, and JC-1 (green/red) in CD4⁺ T cells increased significantly. Compared with HIV-con group, the basal respiration, maximal respiration, ATP production and respiratory potential of CD4⁺ T cells in HIV-SB203580 group increased significantly, and the JC-1 (green/red) in CD4⁺ T cells decreased significantly. Conclusion Abnormal activation of the MAPK signaling pathway is observed in HIV patients receiving ART treatment, especially in CD4⁺ T cells of INR patients, which may lead to impaired mitochondrial function and abnormal CD4⁺ T cell homeostasis.

Objective To study the clinical application value of the upright seated + head down(30° to 45°)+ tongue protrusion technique for the completely exposure of the epiglottic surface under electronic laryngoscopy.Methods Based on the clinical examination process of electronic laryngoscopy in the laryngoscopy room,two methods were applied for the patients with difficulty in exposing the epiglottic surface:① upright seated + tongue protrusion;② upright seated + head down(30° to 45°)+ tongue protrusion.The proportions of patients exposed to the epiglottic surface by these two methods were compared.Results The electronic laryngoscopy examination used the upright seated + tongue protrusion technique allowed for the clear exposure of the epiglottic surface in approximately 73.91%of patients with exposure difficulty.By using the upright seated + head down(30° to 45°)+ tongue protrusion technique,combined with the operator's control over the free movement of the laryngoscope's front end lens into the epiglottic vallecula space for close-range exploration,a 100%clear exploration of the epiglottic surface was achieved.Conclusion The upright seated + head down(30° to 45°)+ tongue protrusion technique for electronic laryngoscopy examination in patients with difficulty in exposing the epiglottic surface can completely expose the epiglottic surface,with significantly clinical effect.It can be used as a supplementary examination method for patients with difficulty in exposing the epiglottic surface in the ordinary upright seated or upright seated + tongue protrusion technique,and has certain clinical application value.

Objective To analyze the effect of immune function on the condition and prognosis of asthma in children with asthma. Methods A total of 148 children with asthma diagnosed in Qinghai women and children's Hospital from January 2018 to January 2021 were included in the analysis, the immune function of the children was determined, and the information of all children was followed up for 6 months after treatment; compared The condition and follow-up prognosis of children with immunocompromised and normal immune function were analyzed and discussed, and the correlation between the expression levels of immunoglobulins (IgG, IgA, IgM) and the condition and short-term recurrence prognosis (6 months) of children was analyzed and discussed, so as to guide Prevention and clinical work. Statistical analysis was done using SPSS19.0. Results The average age of 148 children with recurrent respiratory tract infection in the study was (8.94±3.65) years old, including 70 male children. The condition of the children was evaluated and classified into mild/severe cases: 148 children in this study included mild cases. There were 98 cases and 50 severe cases. There were more males and lower BMI levels in severe children (P<0.05) . The levels of IgG, IgA and IgM in children were all lower in severe children (P<0.05) . The follow-up found that the proportion of relapses in critically ill children was higher (P<0.05). Comparing the levels of IgG, IgA, and IgM in mild and severe children, the average levels of IgG, IgA, and IgM in severe children were lower than those in the mild group, and the difference was statistically significant (P<0.05); recurrence within 6 months of follow-up Prognostic evaluation showed that 19 of the 148 children had relapse, and the levels of IgG, IgA, and IgM in severe relapsed children were significantly lower than those without relapse (P<0.05). Analysis of the relevant factors potentially affecting the prognosis of recurrence showed that gender (female) (OR=1.726) , BMI level (weight loss) (OR=1.613) , IgG expression level factor (low expression) (OR=1.898) , IgA expression Level factor (low expression) (OR=3.509) , IgM expression level factor (low expression) (OR=3.217) and disease factor (severe) (OR=3.619) were potential risk factors, which would increase the risk of poor prognosis. Conclusion The asthma attack in children with immunocompromised immune function is relatively severe, and the short-term recurrence probability is higher, which deserves clinical attention and preventive intervention.
