Objective: To investigate follow-up participation situation, negative conversion, and tuberculosis incidence among boarding junior and senior high school freshmen with latent tuberculosis infection(LTBI) in Zhuhai, so as to provide a reference for better LTBI management in school settings. Methods: A prospective cohort study enrolled 413 LTBI and 27 184 non LTBI boarding junior and senior high school freshmen in Zhuhai from September to October 2023. The LTBI group underwent follow up retesting at >3-6, >6-12, >12-24, >24 months after screening. The followup content included mycobacterium tuberculosis infection testing,chest X ray examination,and questionaire survey(basic demographic information, lifestyle, history of close contact with tuberculosis, and suspected symptoms of pulmonary tuberculosis). Follow-up participation, negative conversion, and tuberculosis incidence were analyzed. Rate was compared by using the Chi-square test, and factors associated with negative conversion were assessed by multivariate Logistic regression analysis. Results: Follow-up participation rates increased initially and then declined, with rates of 25.67% within >3-6 months, 37.05% within >6-12 months, 82.02% within >12-24 months, and 52.21% after 24 months. The overall negative conversion rate was 61.03%. The differences in the conversion rate to negative of mycobacterium tuberculosis infection detection among junior and senior high school freshmen in the LTBI group by different testing methods, school types, smoking history, sleep status, and academic stress were all statistically significant( χ 2=124.96, 22.70, 4.71, 6.31, 6.08, all P <0.05). Multivariate Logistic regression analysis identified testing methods, smoking history, and sleep status as factors associated with negative conversion ( OR =1.90-21.67, all P <0.05). The cumulative incidence of tuberculosis was 726.39 per 100 000 in the LTBI group versus 14.71 per 100 000 in the non-LTBI group ( RR =49.37, 95% CI =11.08-219.87, P <0.01). Conclusions Boarding junior and senior high school freshmen with LTBI in Zhuhai have a higher risk of tuberculosis than concurrent non-LTBI students; they therefore represent a priority group for tuberculosis prevention and control. Centralized follow up is recommended to improve participation, and high specificity methods should be used in follow up retesting and maintain consistency across assessments.

Objective:To analyze the blood-transition prototype components and metabolites of Fengliaoxing Fengshi Dieda medicinal liquor.Methods:Ultra-high performance liquid chromatographyquadrupole/electrostatic field orbital trap high resolution mass spectrometry (UHPLC-Q Exactive Focus MS/MS) technique was used to compare the chromatogram differences of Fengliaoxing Fengshi Dieda medicinal liquor extract, blank serum and drug-containing serum. According to the retention time, relative molecular weight and the ratio with primary and secondary ion fragments provided by MS, the prototype components and metabolites of Fengliaoxing Fengshi Dieda medicinal liquor extract were analyzed in serum of rats after oral administration. The detection conditions were as follows: the mobile phase of methanol (A)-0.1% formic acid solution (B) for elution gradient (0-5 min, 5%A; 5-60 min, 5%-95%A; 60-65 min, 95%A), the flow rate of 0.3 ml/min, heated electrospray ionization, detection range of m/z 80-1 200, positive and negative ion scanning modes.Results:A total of 31 transitional components were detected in the serum, of which 9 were prototype components and 22 were metabolites. The 9 prototype components were identified as phenylacetaldehyde, baogongteng C/ erycibellin, p-coumaric acid, 5-Hydroxymethylfurfural, quinic acid, paeonol, 3-Hydroxybenzaldehyde, salicylic acid, and isourecumenol. The 22 metabolites mainly consist of 11 organic acid components, 3 indole components, 2 organic phenolic components, 2 alkaloid components, 1 nucleoside component, 1 amino acid component, 1 lactone component, and 1 sulfonic component. The metabolic pathways were mainly glucuronidation, sulfation and others, which by phase Ⅱ metabolism.Conclusion:Organic phenols and organic acids are the main components that enter the body of Fengliaoxing Fengshi Dieda Medicinal Liquor, while alkaloid compounds and organic acid components may be potential active ingredients for its pharmacological effects.

Objective:To investigate the risk factors for recurrence after modified Chevron osteotomy for hallux valgus.Methods:A total of 86 patients (102 feet) with hallux valgus who underwent modified Chevron operation in Beijing Jishuitan Hospital from December 2018 to February 2021 were retrospectively analyzed. There were 12 males (14 feet) and 74 females (88 feet), aged 50±15 years (range, 18-74 years). There were 36 cases on the right side, 34 on the left side, and 16 on the bilateral side. 4 feet were treated with Chevron osteotomy, 74 feet with modified McBride's osteotomy, 61 feet with Weil osteotomy, 24 feet with Akin osteotomy, and 23 feet with gastrocnemius aponeurotic release. At the last follow-up, hallux valgus angle (HVA) ≤15° was defined as the non-recurrence group after hallux valgus operation, and HVA>15° was defined as the recurrence group after hallux valgus operation. Compare the age, gender, preoperative HVA, the first and second intermetatarsal angles (IMA) before and after operation, the metatarsus adductus angles (MAA) before and after operation, the Meary angles before and after operation, the distal metatarsal articular angles (DMAA) before and after operation, the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot scores before and after operation, and the rotation of the first metatarsal head between the two groups of patients. Include the indicators with statistically significant differences in the binary variable logistic regression analysis to screen for the risk factors of recurrence after modified Chevron operation for hallux valgus.Results:All patients successfully completed the operation and were followed up for 30.3±16.4 months (range, 12-52 months). Postoperative recurrence occurred in 21 feet, and the recurrence rate was 20.6% (21/102). The HVA at the last follow-up was 8.48°±4.52° in the non-recurrence group and 20.68°±3.61° in the recurrence group. In the non-recurrence group, the AOFAS ankle-hindfoot score increased from 60.31±16.62 points preoperatively to 86.89±12.79 points postoperatively ( t=-13.644, P<0.001). In the recurrent group, the AOFAS ankle-hindfoot score increased from 61.71±15.68 points preoperatively to 84.33±18.84 points postoperatively ( t=-6.082, P<0.001). The proportion of patients with preoperative Meary angle> 4° in the non-recurrence group was 52% (10/21), which was lower than 79% (64/81) in the recurrence group, and the difference was statistically significant (χ 2=6.077, P=0.014). The proportion of patients with square type of metatarsal rotation (type A) in the recurrence group was 58%(47/81), which was higher than 33%(7/21) in the non-recurrence group, and the difference was statistically significant (χ 2=4.081, P=0.043). There was no significant difference in gender, age, preoperative HVA, pre- and post-operative IMA, pre- and post-operative DMAA, pre- and post-operative MAA, or preoperative metatarsal rotation type between the two groups ( P>0.05). The results of the logistic regression analysis showed that a preoperative Meary angle ≤ 4° ( OR=3.299, P=0.024) and a non-type A metatarsal rotation pattern after operation ( OR=4.183, P=0.041) were independent risk factors for recurrence after modified Chevron operation for hallux valgus. Conclusion:Hallux valgus patients with a preoperative Meary angle ≤4° and non-type A metatarsal rotation after operation have an increased risk of recurrence following modified Chevron operation.

Objective:To explore the relationships among psychological resilience,spiritual health,and illness uncertainty in cancer patients,and to analyze the mediating role of disease uncertainty.Methods:The cancer patients were selected by convenience sampling method from Feb 2024 to May 2024 in the Department of Oncology of a Grade Ⅲ-A general hospital in Wuhu City.Data were collected using a general information questionnaire,the Mishel Uncertainty in Illness Scale(MUIS),the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale(FACIT-SP-12,Chinese version),and the Connor-Davidson Resilience Scale(CD-RISC-10).Pearson correlation analysis was conducted to assess the relationships among psychological resilience,illness uncertainty,and spiritual health.The mediating effect of illness uncertainty was tested using Hayes'PROCESS Model 4 and the Bootstrap method.Results:The total scores of spiritual health,psychological resilience and illness uncertainty of cancer patients was(25.11±7.19),(24.36±6.75)and(67.75±13.06),respectively.The spiritual health was positively correlated with psychological resilience(r=0.415,P＜0.01)and negatively correlated with illness uncertainty(r=-0.398,P＜0.01).The psychological resilience was negatively correlated with illness uncertainty(r=-0.668,P＜0.01).Illness uncertainty partially mediated the relationship between psychological resilience and spiritual health,accounting for 35.29%of the total effect.Conclusions:The spiritual health of cancer patients is at a moderate level.Enhancing psychological resilience and reducing illness uncertainty can alleviate psychological burden and improve spiritual health,thereby promoting overall quality of life.

ObjectiveTo evaluate the effects of Wuhua herbal tea on chronic unpredictable mild stress (CUMS)-induced depression and explore its mechanism of action in combating depression.MethodsWe tested the antidepressant effects of Wuhua herbal tea in a rat model of CUMS-induced depression using fluoxetine as a positive control. The rats were divided into four groups: control group, model group, fluoxetine group, and Wuhua herbal tea group. The rats underwent body weight measurements, sucrose preference test, and open-field test. Enzyme-linked immunosorbent assay kits were used to detect the serum levels of serotonin, dopamine, adrenocorticotropic hormone (ACTH), corticosterone, norepinephrine, and interleukin-6. Intergroup comparisons and detection of brain-derived neurotrophic factor (BDNF), cAMP-response element binding protein (CREB), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3) mRNA expression in the hippocampus were performed using RT-PCR. Immunohistochemistry was used to identify the expression of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) proteins in hippocampal paraffin sections of CUMS rats.ResultsCompared with the control group, the model group rats had depressive tendencies, exhibiting low vitality and interest in various behavioral indicators which were signs of despair. The Wuhua herbal tea group statistically increased the levels of serotonin and dopamine in the serum of CUMS rats to varying degrees (P = .015 and P = .002); reduced serum levels of ACTH, corticosterone, norepinephrine, and interleukin-6 (all P .05); and decreased mRNA expression of BDNF, CREB, JAK2, and STAT3 in the hippocampus (all P .05); and decreased p-STAT3 protein levels (P = .006).ConclusionWuhua herbal tea shows antidepressant potential in CUMS rats by modulating the HPA axis and inhibiting JAK2-STAT3 overactivation, alleviating neuroinflammation. It also restores BDNF-CREB pathway function, reducing depressive symptoms.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.
