ObjectiveTo provide evidence for strengthening tuberculosis control in Inner Mongolia by analyzing changes and influencing factors in public awareness of tuberculosis prevention and control information among residents between the early stage and 17 years after the implementation of the directly observed treatment， short-course （DOTS） strategy. MethodsBased on the "National Public Knowledge， Belief and Behavior Questionnaire on Tuberculosis Prevention and Control" designed by the Chinese Center for Disease Control and Prevention， a questionnaire survey was conducted among residents in Inner Mongolia using a multi-stage stratified random sampling method. Chi-square test was used for univariate analysis， and binary Logistic regression was employed to explore the influencing factors of public awareness of tuberculosis prevention and control information. ResultsThe overall awareness rate of core information on tuberculosis prevention and control among the public was 67.7% in 2006， and it decreased to 49.2% in 2023 （P<0.05）. Multivariate Logistic regression analysis showed， compared with the groups aged 15-29， illiterate and semi-illiterate， those with public medical care， and those with three or fewer family members， the awareness rate of the groups aged 60 and above （OR=0.689）， those with primary and junior high school education （OR=0.856）， and those with self-paid medical care （OR=0.468） was significantly lower in 2006. The awareness rate was relatively high in groups with more than 3 family members （OR=1.236） （P<0.05）. Compared with the groups aged 15-29， illiterate and semi-illiterate， married， Han ethnicity， employed， and those receiving public medical care， the awareness rate was higher among the groups aged 30-59 （OR=1.976）， 60 and above （OR=2.224）， those with high school education and above （OR=2.801）， and single （OR=2.244） in 2023. However， the awareness rates of ethnic minorities （OR=0.737）， the unemployed （OR=0.557）， and self-funded medical care （OR=0.497） groups were significantly lower （P<0.05）. ConclusionPublic awareness of TB prevention knowledge in Inner Mongolia remains suboptimal. Strengthening diversified health education campaigns， addressing social stigma， and improving healthcare access are critical to enhance regional TB control outcomes.

The dysfunction of the lysosome and autophagy-lysosome system serves as a driving force for neurodegenerative diseases, metabolic disorders, inflammatory conditions, and other related diseases, closely influencing their onset and progression. Therefore, restoring the function of the lysosome or autophagy-lysosome system has become an increasingly crucial therapeutic strategy in disease management. In this review, we will introduce the lysosomal biogenesis, structure, and function, as well as the biological process of the autophagy-lysosome system. Various diseases closely associated with lysosomal/autophagic dysfunction are also reviewed, emphasizing the significance of targeting the function of the lysosome or autophagy-lysosome system in disease treatment. Finally, we focus on engineered nanomaterials that have the capabilities to restore the function of the lysosome or autophagy-lysosome system, and summarize different strategies and methods for achieving this goal. This review aims to elucidate the latest progress in the field of nanomedicine for lysosomal/autophagic defect-related diseases and inspire the development of innovative and clinically valuable nanomedicines.

Peptide receptor radionuclide therapy (PRRT) with radiolabeled SSTR2 agonists is a treatment option that is highly effective in controlling metastatic and progressive neuroendocrine tumors (NETs). Previous studies have shown that an SSTR2 agonist combined with albumin binding moiety Evans blue (denoted as ¹⁷⁷Lu-EB-TATE) is characterized by a higher tumor uptake and residence time in preclinical models and in patients with metastatic NETs. This study aimed to enhance the in vivo stability, pharmacokinetics, and pharmacodynamics of ¹⁷⁷Lu-EB-TATE by replacing the maleimide-thiol group with a polyethylene glycol chain, resulting in a novel EB conjugated SSTR2-targeting radiopharmaceutical, ¹⁷⁷Lu-LNC1010, for PRRT. In preclinical studies, ¹⁷⁷Lu-LNC1010 exhibited good stability and SSTR2-binding affinity in AR42J tumor cells and enhanced uptake and prolonged retention in AR42J tumor xenografts. Thereafter, we presented the first-in-human dose escalation study of ¹⁷⁷Lu-LNC1010 in patients with advanced/metastatic NETs. ¹⁷⁷Lu-LNC1010 was well-tolerated by all patients, with minor adverse effects, and exhibited significant uptake and prolonged retention in tumor lesions, with higher tumor radiation doses than those of ¹⁷⁷Lu-EB-TATE. Preliminary PRRT efficacy results showed an 83% disease control rate and a 42% overall response rate after two ¹⁷⁷Lu-LNC1010 treatment cycles. These encouraging findings warrant further investigations through multicenter, prospective, and randomized controlled trials.

Objective To investigate the expression characteristics of granzyme B(GZMB)and C-X-C motif chemokine ligand 9(CXCL9)in gastric cancer(GC)tissues,explore their association with the tumor immune microenvironment(TME),and evaluate their clinical prognostic significance.Methods Bioinformatic analyses were conducted using public databases(TIMER,GEPIA,UALCAN)to validate the expression levels of GZMB and CXCL9 across various cancer types,with a focus on GC.Paired tumor and adjacent normal tissue samples were collected from 89 GC patients who underwent radical gastrectomy at Nanyang First People's Hospital between 2018 and 2019.The mRNA expression levels of GZMB and CXCL9 were measured using quantitative real-time PCR(qRT-PCR),and their associations with clinicopathological characteristics were statistically analyzed.Immune cell infiltration levels were estimated using the TIMER and GSCA databases.Diagnostic performance was evaluated through receiver operating characteristic(ROC)curve analysis,while survival outcomes were assessed using data from the Kaplan-Meier Plotter database and patient follow-up records.Results Both database analysis and qRT-PCR results demonstrated that GZMB and CXCL9 expression levels were significantly elevated in GC tissues compared to adjacent non-tumor tissues(P<0.05).Clinical correlation analysis revealed no significant associations between mRNA expression levels of GZMB and CXCL9 and clinicopathological parameters,including gender,age,pathological type,tumor differentiation,TNM stage,tumor size,or lymph node metastasis(P>0.05).Immune infiltration analysis indicated that both genes were significantly positively correlated with CD8+T cell and dendritic cell infiltration(P<0.05),while showing a negative correlation with B cell infiltration(P<0.05).ROC curve analysis showed that the combined detection of GZMB and CXCL9 yielded an AUC of 0.890(95%CI:0.843～0.936),which was higher than that of GZMB alone(AUC=0.832,95%CI:0.772～0.891)or CXCL9 alone(AUC=0.782,95%CI:0.715～0.850).Survival analysis further revealed that patients with high expression of GZMB and CXCL9 had significantly improved overall survival compared to those with low expression(P<0.05).Conclusion GZMB and CXCL9 are highly expressed in GC and are strongly associated with the infiltration of anti-tumor immune cells.These molecules represent promising diagnostic biomarkers for GC,and their elevated expression is correlated with a more favorable prognosis in patients.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Traumatic injuries represent the fifth leading cause of death in China and the primary cause of death among young adults. While facial fractures can lead to significant aesthetic and psychological consequences, fractures in the limbs and joints impair functional mobility. In traumatic incidents requiring forensic evaluation, such as traffic accidents or violent conflicts, the type and severity of fractures directly determine injury grading and disability assessment. Consequently, the accurate diagnosis of traumatic fractures is not only a critical medical issue impacting patient management and rehabilitation but also a significant social issue influencing judicial fairness. This article systematically reviews advancements in multi-modal imaging techniques. While conventional X-ray radiography remains a fundamental screening tool, it faces challenges in detecting occult fractures. Multi-slice spiral computed tomography (MSCT), utilizing 3D reconstruction, enables spatial analysis of complex fractures. Magnetic resonance imaging (MRI), with its multi-sequence capabilities, plays an indispensable role in detecting bone marrow edema and assessing concomitant soft tissue injuries. Regarding innovative technologies, dual-energy computed tomography (DECT) employs virtual non-calcium (VNC) techniques for quantitative bone marrow edema analysis; ultra-high-resolution computed tomography (U-HRCT) breaks through imaging limitations of trabecular microarchitecture with a resolution of approximately 10 μm; and 7.0 T ultra-high-field MRI, alongside MRI-based CT-like imaging techniques, advances radiation-free bone structure evaluation. Artificial intelligence (AI) models significantly enhance diagnostic efficiency in fracture detection. Future developments will focus on multi-modal image fusion, the construction of intelligent decision-support systems, and the quantitative functional assessment of bone microstructure, facilitating a paradigm shift from anatomical description to prognostic prediction and realizing the principles of personalized medicine.

Objective:To observe the morphological characteristics of dome-shaped macula (DSM) and macular hole (MH) in high myopia by optical coherence tomography (OCT), to further explore the correlation between DSM and MH.Methods:A retrospective case-control study. From April 2021 to December 2023, 963 eyes of 503 patients with high myopia (myopic diopter ≥6.00 D) in Department of Ophthalmology of the Fourth Hospital of Hebei Medical University were enrolled in the study. The age of patients ranged from 5 to 89 years old, with the mean age of (48.91±16.69) years. Diopter was -6.00 to -26.00 (-10.49±3.15) D. All eyes were examined by OCT. The width and height of DSM, subfoveal choroidal thickness (SFCT), inner port diameter and base diameter of MH were measured by software on OCT. According to the OCT image features, DSM was divided into horizontal and vertical oval-shaped DSM, and symmetrical round DSM. According to the presence or absence of DSM, the eyes were divided into DSM group and non-DSM group. Then, the affected eyes with MH were divided into DSM with MH group and non-DSM with MH group. The incidence of DSM, the incidence of MH in the DSM group and the non-DSM group, the inner port diameter of MH, the base diameter of MH, SFCT, and the location of retinoschisis (RS) in the DSM with MH group and the non-DSM with MH group were observed. Independent sample t test or non-parametric Mann-Whitney U test was used for comparison between groups. Pearson correlation analysis was used to analyze the related factors of MH inner port diameter, base diameter and DSM width, height, height/width ratio. Results:Among the 963 eyes, the DSM group and the non-DSM group were 266 (27.6%, 266/963) and 697 (72.4%, 697/963) eyes. Compared with the non-DSM group, patients in the DSM group were older ( Z=-11.302), had higher degree of myopia ( Z=-8.944), thinner SFCT ( Z=-16.244), and higher incidence of MH ( χ2=8.828), and the differences were statistically significant ( P<0.05). Compared with non-DSM with MH group, the patients in DSM with MH group were older ( t=2.610), higher myopia diopter ( t=3.593), and thinner SFCT ( t=3.505), the differences were statistically significant ( P<0.05). There was no significant difference in the number of eyes in the epiretinal membrane between the two groups ( χ2=0.119, P=0.730). In the DSM with MH group, RS mostly occurred in the outer retina with a large range, while in the non-DSM with MH group, RS mostly occurred in the outer and inner retina with a small range. There was a statistically significant difference in the number of eyes at different positions of RS between the two groups ( χ2=25.131, P<0.05). The results of correlation analysis showed that there was no correlation between the inner port and base diameter of MH and the width, height, height/width ratio of DSM ( P>0.05). Conclusions:Compared with high myopia patients without DSM, patients with DSM are older, have more severe myopia and thinner SFCT. In DSM patients with MH, RS often occurs in the outer retina and has a large range. There was no significant association between DSM morphology and MH size.

Objective:To investigate the clinical efficacy of extended abdominal wall resec-tion combined with reconstruction for abdominal wall aggressive fibromatosis (AF).Methods:The retrospective and descriptive study was conducted. The clinical data of 70 patients with abdominal wall AF who were admitted to 3 medical centers, including The First Affiliated Hospital of the University of Science and Technology of China, between January 2009 and July 2024 were collected. There were 6 males and 64 females, aged (36±13)years. All patients underwent extended abdominal wall resection combined with abdominal wall reconstruction. Observation indicators: (1) surgical situations; (2) tumor recurrence and postoperative complications. Comparisons of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1)Surgical situations. All 70 patients underwent extended abdominal wall resection combined with abdominal wall recons-truction. The operation time was 90(91)minutes and duration of postoperative hospital stay was 10(6)days. Of the 70 patients, 41 patients underwent abdominal wall AF resection plus polypropylene mesh abdominal wall reconstruction, with a defect area of 60(54)cm2. The mesh placement method was uniformly Sublay repair. The remaining 29 patients underwent abdominal wall AF resection plus direct suture repair, with a defect area of 34(31)cm2. There was a significant difference in the abdominal wall defect area between the two groups ( U=291.00, P<0.05). All 70 patients achieved R 0 resection. The distance from surgical margin to tumor edge was 2-3 cm in 39 cases and >3 cm in 31 cases. (2) Tumor recurrence and postoperative complications. All 70 patients were followed up for 78(90)months. During follow-up, 10 patients developed tumor recurrence (5 cases with mesh reinforced abdominal wall reconstruction and 5 cases with direct suture repair). Among them, one case was monitored, one case underwent radiotherapy, and neither received further surgical treatment. The remaining 8 patients underwent repeat R 0 resection, and no further recurrence occurred. There was no significant difference in recurrence rate between the patients with mesh reconstruction and patients with direct suture repair ( χ2=0.06, P>0.05). The postoperative recurrence rate was 9.7%(3/31) in patients with the distance from surgical margin to tumor edge >3 cm, versus 17.9%(7/39) in patients with the distance from surgical margin to tumor edge of 2-3 cm, showing no significant difference between them ( χ2=0.97, P>0.05). Sixty patients had no tumor recurrence. During follow-up, none of the 70 patients developed incisional hernia. Two patients experienced postoperative wound infection, and 6 cases developed postoperative chronic pain. Conclusion:Extended abdominal wall resection combined with reconstruction is safe and feasible for abdominal wall AF.
