Objective: To analyze the school tuberculosis (TB) outbreaks and preventive treatment in Hefei from 2022 to 2024, so as to provide reference for TB prevention and control in schools. Methods: Data were collected on all school based TB outbreaks occurring during 2022-2024 in Hefei, defined as ≥2 epidemiologically linked TB cases within the same school during a single semester. Statistical analyses were performed using the Chi square test. Results: Close contacts exhibited significantly higher TB incidence (2.88%) and latent mycobacterium tuberculosis infection (LTBI) rates (13.80%) in the school TB outbreaks, compared to non close contacts (0.12% and 2.63%, respectively). Among close contacts, secondary school students showed lower TB incidence (0.48%) and LTBI prevalence (3.42%) than both primary school or younger children (0.68%, 6.95%) and college students ( 0.78% , 6.50%), with statistically significant differences ( χ 2=360.91, 6.37; 791.71, 102.03, all P <0.05). The proportion of LTBI individuals recommended for preventive therapy was higher in primary school or younger groups (98.59%) than in secondary (95.25%) or college students (86.34%) ( χ 2=25.86, P <0.01). However, among those recommended, close contacts had higher uptake (85.82%) and completion rates (87.25%) of preventive therapy than non close contacts (69.63% and 70.57%); similarly, secondary school students demonstrated higher uptake (91.21%) and completion rates (86.45%) compared to primary school or younger (88.57%, 83.87%) and college students (57.28%, 64.08%) ( χ 2=30.52, 26.72; 125.17, 38.84, all P <0.01). Subsequent TB incidence among LTBI close contacts (13.30%) and among those who did not complete preventive therapy (22.73%) were significantly higher than among non close contacts (2.80%, 2.41%), respectively ( χ 2=32.19, 13.87, both P <0.05). Conclusions In school TB outbreaks, close contacts face higher LTBI prevalence and subsequent TB risk than non close contacts. College students show notably low adherence to preventive therapy. It is necessary to take targeted measures to improve the compliance of preventive measures among students.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective:To investigate the relationship between alterations in dynamic functional connectivity (dFC) and spatial navigation abilities in individuals with subjective cognitive decline (SCD) across different Traditional Chinese Medicine (TCM) constitutions.Methods:Seventy-five participants with SCD, comprising 34 individuals with balanced constitutions and 41 individuals with biased constitutions, were recruited from the Affiliated Drum Tower Hospital of Nanjing University Medical School between August 2022 and January 2025. The participants underwent TCM constitution assessment, spatial navigation ability testing, and neuropsychological scale evaluation. Additionally, each participant was assessed using 3.0 T resting-state functional magnetic resonance imaging (rs-fMRI) and high-resolution T1-weighted imaging scans. Based on prior research, 20 spatial navigation-related regions of interest (ROIs) were defined. Afterwards, rs-fMRI time series were segmented using a sliding time window approach before calculating the dFC within the spatial navigation brain network.Results:Compared to the balanced constitution group, the biased constitution SCD group showed significantly lower scores on the Mini-Mental State Examination (MMSE) ( z=-3.05, P=0.002) and the Auditory Verbal Learning Test (AVLT) measures: immediate recall ( z=-2.12, P=0.035), short-delay recall ( z=-2.22, P=0.026), long-delay recall ( z=-2.88, P=0.004), cued recall ( z=-2.91, P=0.004), and recognition ( z=-2.20, P=0.028). They also exhibited significantly higher average error distances in ego-allocentric navigation ( z=-2.28, P=0.023), egocentric navigation ( z=-2.31, P=0.021), and delayed navigation ( z=-2.02, P=0.043). Participants with SCD who had a biased constitution also demonstrated significantly reduced dFC between the left parahippocampal gyrus (PHG) and left prefrontal cortex (PFC) ( t=2.43), right precuneus and right retrosplenial cortex (RSC) ( t=2.96), and left inferior parietal lobule (IPL) and left hippocampus ( t=2.42) (all P<0.05, Bonferroni-corrected). Conversely, the dFC was significantly increased between the right PHG and left PFC ( t=-2.29, P<0.05, Bonferroni-corrected). Significant correlations were also found in participants with SCD who had biased constitutions: the dFC between the left PHG and left PFC positively correlated with the egocentric navigation average total error ( r=0.34, P=0.030) and negatively correlated with the visuospatial memory cognitive domain ( r=-0.35, P=0.026); the dFC between the left IPL and left hippocampus negatively correlated with the egocentric navigation average total error ( r=-0.32, P=0.043); and the dFC between the right PHG and left PFC positively correlated with the delayed navigation average total error ( r=0.33, P=0.037). The area under the ROC curve for the combined differences in cognitive assessments, spatial navigation behavior, and navigation-related brain network dFC was 0.966 in predicting biased constitution versus balanced constitution in participants with SCD. Conclusions:Individuals with SCD and biased constitutions demonstrated poorer spatial navigation ability, possibly due to altered dFC within the spatial navigation brain network. Furthermore, the integrated model based on spatial navigation behaviors and dFC exhibited a high predictive value in distinguishing between individuals with SCD who had balanced and biased constitutions.

To summarise the clinical experience of treating insomnia with the method of resolving depression， regulating the middle， and tranquilising mind. It is believed that the key to the pathogenesis of insomnia lies in qi depression， disharmony of qi pivot， and disharmony of qi and blood， and the core treatment is to resolve depression， regulating the middle， and tranquilising mind. The self-prescribed Jieyu Anmian Formula （解郁安眠方） could be used as the basic treatment， then modified according to the performance of the patient and syndromes. For syndrome of liver depression restricting spleen， the treatment should soothe liver and invigorate spleen， resolve depression and regulate the middle； for syndrome of liver depression and phlegm coagulation， the treatment should resolve depression and phlegm， support the earth and free the wood； for syndrome of liver depression transforming into fire， the treatment should soothe liver and clear fire， resolve depression and dysphoria； for syndrome of qi stagnation and blood stasis， the treatment should activate blood and regulate the middle， resolve depression and tranquilise mind.

OBJECTIVES: To develop a scale for evaluating responsive feeding behaviors among caregivers of children aged 0-24 months in China, and to examine its reliability and validity. METHODS: An initial item pool was constructed through literature review, expert panel discussions, and caregiver interviews. Items were screened and revised using expert consultation and item analysis. A total of 523 caregivers of children aged 0-24 months were randomly selected from urban community health service centers in Nanjing for a formal survey to assess the scale's reliability and validity. RESULTS: The scale comprised two age-specific subscales: 0-6 months (4 dimensions, 18 items) and 7-24 months (5 dimensions, 29 items). Cronbach's alpha values for the two subscales were 0.766 and 0.850, respectively; split-half reliability coefficients were 0.616 and 0.716. Content validity indices were 0.83 for the 0-6 months subscale and 0.86 for the 7-24 months subscale. Confirmatory factor analysis supported the structural validity of both subscales, with all fit indices within acceptable ranges. CONCLUSIONS The two age-specific subscales demonstrate good reliability and validity and can serve as practical tools for assessing caregivers' responsive feeding behaviors in children aged 0-24 months, suitable for clinical application and dissemination.

Objective To explore the effect of tongue pressure resistance feedback training in the rehabilitation of dysphagia in patients with ischemic stroke(IS).Methods A total of 100 pa-tients with dysphagia after IS were randomly divided into control group(receiving conventional reha-bilitation therapy and oral motor training)and experimental group(receiving tongue pressure resist-ance feedback training on the basis of conventional rehabilitation therapy),with 50 patients in each group.The treatment duration was 4 weeks for both groups.During the study,3 patients dropped out due to personal reasons,and ultimately 49 patients in the control group and 48 patients in the experi-mental group completed the study.Before and after treatment,tongue muscle function was measured in both groups;videofluoroscopic swallowing studies(VFSS)were used to measure temporal and kinemat-ic parameters of swallowing;the Rosenbek Penetration-Aspiration Scale(PAS)was used to assess aspi-ration risk;the Stroke and Aphasia Quality of Life Scale(SWAL-QOL)was used to evaluate quality of life;and occurrence of complications in both groups were compared.Results After 4 weeks of treat-ment,peak tongue pressure,mean tongue pressure,and tongue pressure duration increased inboth groups,with these indicators being higher in the experimental group than in the control group;oral transit time,soft palate elevation time,and hyoid bone displacement time shortened,while upper esoph-ageal sphincter(UES)opening time and laryngeal closure time prolonged,hyoid and thyroid cartilage movement(upward and anterior displacement)and UES opening degree increased,and pharyngeal contractile ratio(PCR)decreased in both groups,with these indicators being superior in the experi-mental group compared to the control group;PAS scores decreased and SWAL-QOL scores increased in both groups,with PAS scores being lower and SWAL-QOL scores being higher in the experimental group compared to the control group;the differences between the two groups in the aforementioned indicators were statistically significant(P＜0.05).The complication rate was 4.17％(2/48)in the experimental group and 10.20％(5/49)in the control group,with no statistically significant difference(P＞0.05).Conclusion Tongue pressure resistance feedback training can improve tongue function and swallowing function,effectively reduce the risk of aspiration after swallowing,and enhance the quality of life of patients with dysphagia after IS during their rehabilitation treatment.

In 2023, new diagnostic criteria were proposed to distinguish myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) from other inflammatory diseases of the central nervous system.With typical clinical presentation and neuroimaging features, the seropositive status of anti-myelin oligodendrocyte glycoprotein-IgG (MOG-IgG) is essential for the diagnosis of MOGAD.Advances in cell transfection immunofluorescence assays have improved diagnostic accuracy in the last few years, but there are differences in the positive predictive value of serum MOG-IgG titers in the context of different MOGAD prevalence.Therefore, alternative diagnostic methods need to be further explored, and the clinical significance of low MOG-IgG titers should be carefully interpreted.In this review, the main clinical features, current understanding and challenges of MOGAD were discussed, including uncertainties about the specificity and pathogenicity of myelin oligodendrocyte glycoprotein autoantibodies and the need to identify immunopathological targets for future therapies.Moreover, it is necessary to search for and validate biomarkers that can help diagnose and detect disease activity, and it is important to identify MOGAD patients who need long-term immunotherapy.

Objective To explore the diagnosis and treatment strategies for elderly patients with ground-glass opacity (GGO). Methods The imaging features and postoperative pathological findings of the elderly patients with pulmonary GGO receiving surgery in our hospital from 2017 to 2019 were retrospectively analyzed. The patients were divided into an elderly patient group and a non-elderly patient group based on their age. Results Finally 575 patients were included in the study. There were 281 elderly patients, including 83 males and 198 females, with an average age of (67.0±5.3) years. There were 294 non-elderly patients, including 88 males and 206 females, with an average age of (49.1±7.3) years. Compared with the non-elderly patients, elderly GGO patients showed the following distinct clinical features: long observation time for lesions (P=0.001), high proportion of rough edges of GGO (P<0.001), significant pleural signs (P＜0.001) and bronchial signs (P＜0.001), and high proportion of type Ⅱ-Ⅳ GGO (P<0.001), lobectomy type (P=0.013), and invasive lesions reported in postoperative pathology (P<0.001). There was no statistical difference in the average hospital stay between the two groups (P=0.106). Multivariate logistic regression analysis showed that GGO diameter and GGO type were the main factors affecting the operation. Observation time, GGO diameter, GGO type and pleural signs were the main influencing factors for postoperative pathological infiltrative lesions. The cut-off value of GGO diameter in predicting infiltrating lesions was 10.5 mm in the elderly patients group. Conclusion The size and type of GGO are important factors in predicting invasive lesions and selecting surgical methods. Elderly patients with radiographic manifestations of type Ⅱ-Ⅳ GGO lesions with a diameter greater than 10.5 mm should be closely followed up.

With reference to the Information and Documentation-Resource Description (GB/T 3792-2021) and Bibliographical Description for Ancient Chinese Books (GB/T 3792.7-2008) and other cataloging standards and rules, drawing on the practical experience of cataloging ancient TCM books, Bibliographical Cataloging for Ancient TCM Books was formulated. This standard specifies the entry items and their order of ancient TCM books, cataloging identifier, cataloging text, cataloging information source, and cataloging item details. The standard can provide standardized and unified guiding principles and methods for the work of ancient TCM books, and promote the sharing and utilization of ancient TCM books.

Hepatocellular carcinoma(HCC), the third leading cause of cancer-related death worldwide, is characterized by high mortality and recurrence rates. Common treatments include hepatectomy, liver transplantation, ablation therapy, interventional therapy, radiotherapy, systemic therapy, and traditional Chinese medicine(TCM). While exhibiting specific advantages, these approaches are associated with varying degrees of adverse effects. To alleviate patients' suffering and burdens, it is crucial to explore additional treatments and elucidate the pathogenesis of HCC, laying a foundation for the development of new TCM-based drugs. With emerging research on gut microbiota, it has been revealed that microbiota plays a vital role in the development of HCC by influencing intestinal barrier function, microbial metabolites, and immune regulation. TCM, with its multi-component, multi-target, and multi-pathway characteristics, has been increasingly recognized as a vital therapeutic treatment for HCC, particularly in patients at intermediate or advanced stages, by prolonging survival and improving quality of life. Recent global studies demonstrate that TCM exerts anti-HCC effects by modulating gut microbiota, restoring intestinal barrier function, regulating microbial composition and its metabolites, suppressing inflammation, and enhancing immune responses, thereby inhibiting the malignant phenotype of HCC. This review aims to elucidate the mechanisms by which gut microbiota contributes to the development and progression of HCC and highlight the regulatory effects of TCM, addressing the current gap in systematic understanding of the "TCM-gut microbiota-HCC" axis. The findings provide theoretical support for integrating TCM with western medicine in HCC treatment and promote the transition from basic research to precision clinical therapy through microbiota-targeted drug development and TCM-based interventions.
