Tuberculosis (TB) remains a major global public health threat. The World Health Organization (WHO) 2020–2024 global TB reports provide a comprehensive overview of the TB situation from 2019 to 2023. In 2023, TB re-emerged as the world's leading infectious killer, with an estimated 10.8 million new cases. While the growth in the incidence rate slowed, the number of deaths decreased to 1.25 million. The COVID-19 pandemic significantly disrupted TB control efforts in 2020–2021. As control measures are gradually restored, a positive trend in TB control is emerging. However, significant regional disparities in incidence persist, with eight high-burden countries, including India and China, accounting for over two-thirds of the global total. In 2023, global treatment coverage for drug-resistant TB (DR-TB) was 44.00% with a treatment success rate of 68.00%; yet, with 400 000 new drug-resistant cases, the control situation remains severe. China has achieved remarkable progress in TB control: new cases fell to 741 000 in 2023 (an incidence of 52 per 100 000); mortality decreased significantly; its share of the global DR-TB burden dropped from 14.00% to 7.30%; and the TB/HIV co-infection rate declined from 1.68% in 2019 to 0.66% in 2023, outperforming the global average. Globally, control measures continue to be optimized: treatment coverage increased from 70.00% in 2019 to 75.00% in 2023, the number of people receiving preventive therapy grew to 4.7 million, and rapid diagnostic coverage reached 48.00%. In China, the number of patients treated recovered to 565 000 in 2023, and rapid diagnostic coverage rose to 74.00%. Although technological innovations have enhanced the efficiency of prevention, screening, diagnosis, treatment, and management, achieving the 2030 End TB Strategy goals will require strengthening TB management, building primary healthcare capacity, and targeting interventions for high-risk populations, while balancing resource allocation with technological innovation to address the challenges of a heterogeneous global epidemic.

The development of bone in human body and the maintenance of bone mass in adulthood are regulated by a variety of biological factors. Myocyte enhancer factor 2C (MEF2C), as one of the many factors regulating bone tissue development and balance, has been shown to play a key role in bone development and metabolism. However, there is limited systematic analysis on the effects of MEF2C on bone tissue. This article reviews the role of MEF2C in bone development and metabolism. During bone development, MEF2C promotes the development of neural crest cells (NC) into craniofacial cartilage and directly promotes cartilage hypertrophy. In terms of bone metabolism, MEF2C exhibits a differentiated regulatory model across different types of osteocytes, demonstrating both promoting and other potential regulatory effects on bone formation, with its stimulating effect on osteoclasts being determined. In view of the complex roles of MEF2C in bone tissue, this paper also discusses its effects on some bone diseases, providing valuable insights for the physiological study of bone tissue and strategies for the prevention of bone diseases.

Avian influenza H10N3 is a type of avian influenza virus that can occasionally infect humans and cause severe pneumonia and acute respiratory distress syndrome (ARDS). On December 25, 2024, a 23-year-old obese female patient with H10N3 avian influenza complicated with severe ARDS was admitted to the Fourth People's Hospital of Nanning. The patient was transferred to our department due to "fever, cough, and shortness of breath for 13 days". Physical examination revealed moist rales in bilateral lungs. Chest imaging showed large areas of ground-glass opacity and consolidation in both lungs. Based on the patient's medical history, clinical manifestations, and laboratory findings, she was diagnosed with human infection of H10N3 avian influenza, severe pneumonia, and severe ARDS. Supported by mechanical ventilation and extracorporeal membrane oxygenation (ECMO), daily monitoring of airway peak pressure, plateau pressure (Pplat), driving pressure (ΔP), and lung compliance was performed to guide the adjustment of tidal volume (VT) and positive end-expiratory pressure (PEEP) during invasive mechanical ventilation. Medications including anti-avian influenza virus agents, antibacterial drugs, and antifungals were administered. Eventually, the patient's condition improved gradually, and she was successfully weaned from ECMO. No ventilator-induced lung injury (VILI) or multiple organ dysfunction syndrome (MODS) related to ARDS occurred during ECMO support. However, during the final stage of ventilator weaning after the restoration of spontaneous breathing, a right pneumothorax occurred. Closed thoracic drainage was performed, after which the ventilator was successfully discontinued. The patient was successfully transferred out of the intensive care unit (ICU), recovered fully, and was discharged from the hospital. In the invasive mechanical ventilation management of patients infected with H10N3 avian influenza complicated by ARDS, monitoring airway peak pressure, Pplat, ΔP, and assessing pulmonary compliance may facilitate more standardized management of such ARDS patients and help reduce VILI.

Objective: To construct a 5G unmanned aerial vehicle (UAV) airport platform for blood transportation and explore its feasibility and advantages within the blood emergency support system. Methods: Based on 5G high-speed network transmission technology, a UAV management system was designed to achieve a closed-loop management of the entire transportation process, including blood distribution, route information, flight status, emergency dispatch, hospital reception, real-time temperature monitoring, and video surveillance. Integrated with an open UAV airport, the first "5G UAV Blood Transportation Intelligent Airport Platform" was established. Results: At present, the platform has settled in 2 sets of UAV systems, established 17 routes, and carried out regular UAV blood transportation services for 15 hospitals. From January 1, 2024 to June 30, 2025, a total of 12 134 sorties were completed, with a total transported blood weight of 7 692.38 kg, including 25 500 units of red blood cells, 3 824.5 units of platelets, 1 350 370 mL of plasma, and 10 810 units of cryoprecipitate. Compared to land transportation, UAV delivery saved an average of 46.8 minutes during rush hours (maximum: 89.3 minutes) and an average of 32.3 minutes during non-rush hours (maximum: 59.1 minutes). In terms of the quality of UAV blood transportation, the temperature of suspended red blood cells was between 4 and 8℃, that of platelets was between 20 and 24℃, and that of plasma was below 0℃. No damage has occurred so far. Conclusion: The UAV blood transportation platform can stably provide blood delivery services during both routine and emergency conditions, ensuring timely blood delivery and stable blood quality.

This article comprehensively reviews the application of NOAC in patients with liver cirrhosis， discusses their advantages and potential risks， analyzes their pharmacokinetic and pharmacodynamic characteristics， and evaluates their efficacy and safety in the prevention and treatment of cirrhosis-associated thrombosis based on clinical evidence， in order to provide a reference for clinical decision-making.

Objective To investigate the protective effects of secretomes released by three-dimensional cultured mesenchymal stem cells(MSCs)on neurons subjected to seawater immersion(SW)and stretch injury(SI),and to provide new insights into neuronal repair following SW combined with traumatic brain injury(TBI).Methods MSCs were cultured using the hanging drop method,and the conditioned medium(CM)containing MSCs secretomes was collected.A cellular model combining SW with SI was established using mouse hippocampal neuronal cells(HT22 cells).HT22 cells were randomly assigned to five groups:control,SI,SI+SW,SI+CM,and SI+SW+CM groups.Cell viability was assessed using the CCK-8 assay,apoptosis rate was measured by flow cytometry,cell migration ability was evaluated by scratch assay,and the expression levels of apoptosis-related proteins Bcl-2 and Bcl-2-associated protein(Bax),and ferroptosis-related proteins long-chain acyl-CoA synthetase 4(ACSL4)and cyclooxygenase-2(COX-2)were detected by Western blotting.Results Immersion in 15%seawater for 12 h significantly decreased HT22 cell viability(P<0.05).The CCK-8 assay indicated that cell viability in both the SI and SI+SW groups was significantly lower than that in control group after 12 h of treatment(P<0.05).Treatment with CM containing MSCs secretomes significantly increased cell viability in SI+CM group compared to SI group(P<0.0001),and in SI+SW+CM group compared to SI+SW group(P<0.001).Flow cytometry results revealed that the apoptosis rate in SI and SI+SW groups was significantly higher than that in control group(P<0.05 or P<0.001),while in SI+CM group was lower than that in SI group(P<0.05),and in SI+SW+CM group was lower than that in SI+SW group(P<0.05).Western blotting showed that compared to control group,SI and SI+SW groups exhibited reduced Bcl-2 expression level(P<0.01 or P<0.0001)and increased expression levels of Bax,ACSL4,and COX-2(P<0.01 or P<0.0001).Compared to SI group,the SI+CM group displayed increased Bcl-2 expression level(P<0.05)and decreased expression levels of Bax,ACSL4,and COX-2(P<0.05).Compared to SI+SW group,SI+SW+CM group exhibited increased Bcl-2 expression level(P<0.01)and decreased expression levels of Bax,ACSL4,and COX-2(P<0.01 or P<0.001).Scratch assay results demonstrated that at both 12 h and 24 h,the cell migration rate in SI and SI+SW groups was significantly lower than that in control group(P<0.01 or P<0.0001),while the migration rate in SI+CM group was significantly higher than that in SI group(P<0.0001 or P<0.01),and the migration rate in SI+SW+CM group was significantly higher than that in SI+SW group(P<0.0001).Conclusion Secretomes derived from MSCs cultured using the hanging drop method can alleviate neuronal damage caused by SW and TBI,potentially offering a therapeutic approach for SW combined with TBI.

Objective To construct a finite element analysis model for the treatment of calcaneal fracture for Sanders Ⅲ type calcaneal by using simulated sustentaculum tali sustentacular screw placement,and to explore the effectiveness of the treatment of Sanders typeⅢcalcaneal fracture.Methods The finite element analysis method was used to study the effectiveness of the treatment of Sanders Ⅲ calcaneal fracture.Three calcaneal specimens of a healthy adult were taken for Micro-CT scanning to obtain the CT sections data,then Mimics 21.0 and Geomagic Wrap 2017 software were used to reconstruct the three-dimensional model of normal calcaneal bone,and SolidWorks 2017 software was used to map the internal fixation and fracture model according to the clinical fracture cases,and simulated surgery was performed.The data obtained were imported into ANSYS 17.0 finite element analysis software for material assignment and mesh division to establish a three-dimensional finite element model.The load and boundary constraints were applied to each model to perform finite element analysis and calculation,and then the stress of the finite element model and the maximum displacement of the fracture end were extracted.Results The maximum stress of the overall structure of each model was concentrated on internal fixation,in which the maximum stress of sustentaculum tali fracture and the maximum stress of screws in all fracture models are located on the sustentaculum tali sustentacular screw.The displacement of fracture end in each finite element model was less than 0.15 mm,and no internal fixation failure occurred.Conclusion It is effective to simulate the treatment of calcaneal fracture of Sanders type Ⅲ by using of sustentaculum tali sustentacular screw.

Objective To compare the detection rate and safety of transrectal cognitive fusion prostate biopsy and trans-perineal multiparametric MRI-transrectal ultrasound(mpMRI-TRUS)fusion-guided prostate biopsy.Methods The clinical data of 462 patients who underwent mpMRI at the Eastern Theater Command General Hospital from June 2021 to May 2025 were analyzed retrospectively.All patients had at least one suspicious lesion with a PI-RADS score ≥3 and subsequently underwent targeted prostate biopsy.The results of targeted biopsy combined with systematic biopsy were defined as the combined biopsy re-sults.The PCa detection rate,clinically significant PCa(csPCa)detection rate and incidence of complications were compared be-tween the two groups.Diagnostic performances of systematic,targeted and combined biopsies were also compared between the two approaches.Results In targeted biopsy,the transperineal group had significantly higher PCa and csPCa detection rates than those of the transrectal group(48.11％vs 38.19％,and 39.31％vs 29.17％,P＜0.05).There was no significant difference between the two groups in PCa and csPCa detection rates for systematic or combined biopsy(P＞0.05).The inci-dence rate of postoperative complications in the transperineal group was significantly lower than that of the transrectal group(14.78％vs 23.61％,P＜0.05).The detection rate of combined approach was significantly higher than that in either systemat-ic or targeted biopsy alone(P＜0.05).Conclusion Compared to the transrectal approach,transperineal mpMRI-TRUS image fusion-guided prostate biopsy demonstrates greater safety and higher accuracy in targeted biopsy.The combined biopsy strategy can effectively reduce the risk of missed diagnoses in patients with PCa.

Objective To explore the role and mechanism of RNA m6A methyltransferase Wilms'tumor 1-associated protein(WTAP)in epithelial-mesenchymal transition(EMT)of glioblastoma cells and its association with transcription factor JUNB.Methods(1)Based on the Cancer Genome Atlas(TCGA)and Genotype-Tissue Expression(GTEx)databases,the expression levels of transforming growth factor β(TGF-β),WTAP,and JUNB in glioblastoma multiforme(GBM)and normal brain tissues were analyzed,as well as their diagnostic and prognostic values for GBM.The correlation of TGF-β,WTAP,and JUNB with gliomas of different WHO grades was analyzed using the Chinese Glioma Genome Atlas(CGGA)database.Spearman correlation analysis was performed to assess the correlation between TGF-β and m6A methyltransferases.(2)An EMT model was established in human astrocytoma U87-MG cells through TGF-β1 induction.qRT-PCR and Western blotting were employed to detect the expression levels of WTAP,JUNB,matrix metalloproteinase 2(MMP2),and N-cadherin.The migration capacity of U87-MG cells was evaluated by wound-healing and Transwell assays.An m6A RNA methylation quantification kit(colorimetric)was used to detect RNA m6A methylation modification levels.A stable cell line with low expression of WTAP was constructed to investigate the effects of WTAP knockdown on the migration ability of U87-MG cells,as well as the expression of JUNB.(3)A protein-protein interaction network was constructed using STRING database and GeneMANIA database,followed by gene ontology(GO)and KEGG pathway enrichment analyses to explore the biological processes,molecular functions,cellular components,and signaling pathways potentially involved in TGF-β/WTAP/JUNB.Gene set enrichment analysis(GSEA)was performed on JUNB-related genes to investigate their potential downstream signaling pathways.Results(1)The expression levels of TGF-β,WTAP,and JUNB were significantly higher in GBM(P<0.001),positively correlated with WHO grades of glioma(P<0.001).Glioma patients with high expression of all three genes had shorter overall and disease-free survival(P<0.001).Spearman analysis showed that the expression of TGF-β in GBM was positively correlated with WTAP(r=0.175,P=0.023),but no significant correlation with other m6A methyltransferases(P>0.05).(2)After TGF-β1 treatment,the level of m6A methylation modification of total RNA in U87-MG cells significantly increased(P<0.001).Wound-healing assay and Transwell assay results showed that the migration ability of U87-MG cells was significantly increased after TGF-β1 treatment(P<0.01),while WTAP knockdown significantly reduced the migration ability of U87-MG cells(P<0.01).qRT-PCR and Western blotting results showed that the mRNA and protein expression levels of WTAP,N-Cadherin,MMP2,and JUNB in U87-MG cells were significantly increased after 48 h of TGF-β1 induction(P<0.001),while WTAP knockdown significantly reduced the mRNA and protein expression of JUNB(P<0.001).(3)The TGF-β/WTAP/JUNB-related protein-protein interaction network was constructed,which was primary involved in mRNA modification and EMT.GSEA results showed that JUNB-related signaling pathways were closely associated with glioma malignant progression.Conclusions TGF-β,WTAP,and JUNB are all associated with GBM malignant progression and poor patient prognosis.TGF-β may enhance total RNA m6A modification by promoting the expression of m6A methyltransferase WTAP,and WTAP subsquentaly upregulates transcription factor JUNB,thereby promoting EMT and malignant progression of GBM.

Sepsis is a systemic inflammatory response caused by severe infection or trauma, and is one of the common causes of acute lung injury(ALI) and acute respiratory distress syndrome(ARDS). Sepsis-acute lung injury(SALI) is a critical clinical condition with high morbidity and mortality. Its pathogenesis is complex and not yet fully understood, and there is currently a lack of targeted and effective treatment options. Pyroptosis, a novel form of programmed cell death, plays a key role in the pathological process of SALI by activating inflammasomes and releasing inflammatory factors, making it a potential therapeutic target. In recent years, the role of traditional Chinese medicine(TCM) in regulating signaling pathways related to pyroptosis through multi-components and multi-targets has attracted increasing attention. TCM may intervene in pyroptosis by inhibiting the activation of NLRP3 inflammasomes and regulating the expression of Caspase family proteins, thus alleviating inflammatory damage in lung tissues. This paper systematically reviews the molecular regulatory network of pyroptosis in SALI and explores the potential mechanisms and research progress on TCM intervention in cellular pyroptosis. The aim is to provide new ideas and theoretical support for basic research and clinical treatment strategies of TCM in SALI.
