Objective:To systematically explore the expression characteristics,molecular functions,and clinical prognostic associations of the SNX22 in thyroid carcinoma(THCA)through bioinformatics analysis and clinical data vali-dation,providing a novel perspective for precision medicine in thyroid cancer.Methods:Gene expression and clinical data of THCA were obtained from the TCGA and GEO databases(GSE3678,GSE65144,GSE82208).R software was used for data preprocessing,differentially expressed gene(DEG)screening,and survival analysis.The expression pat-terns,prognostic value,and immune regulatory roles of SNX22 were evaluated using PPI networks,TIMER/SCNA im-mune correlation analysis,and ESTIMATE scores.Results:Thirteen intersecting DEGs were identified from GEO data-sets,with SNX22 showing significantly higher expression in THCA tumor tissues than in normal tissues(P<0.05).Kaplan-Meier analysis revealed that high SNX22 expression was significantly associated with overall survival(OS)in THCA pa-tients(P=0.001,HR=1.70),with an ROC curve AUC of 0.745.Subgroup analysis indicated significantly elevated SNX22 expression in patients aged≤45 years and with N1 staging(P<0.05).Immune correlation analysis showed that SNX22 expression positively correlated with infiltration of multiple immune cells(P<0.05),while copy number deletions were as-sociated with reduced immune cell infiltration(P<0.05).Conclusion:SNX22 is highly expressed in thyroid cancer and is significantly associated with poor prognosis and immune microenvironment remodeling,thus having the potential to serve as a prognostic marker and immunotherapy target.

In recent years,the market share of food and medicine homology substances has continued to grow,and various types of contamination issues have become the focus of attention both inside and outside the industry.The contamination not only affects the original medicinal quality,but also leads to the accumulation of toxic substances in the human body,causing acute and chronic severe hazards such as vomiting,poisoning and cancer.Therefore,the development of biosensors that can conveniently,accurately and sensitively detect various pollutants in food and medicine homology substances has become a research hotspot.Aptasensors based on metal-organic frameworks(MOFs)with advantages such as strong specificity,rapid response and simple operation,have been widely used in detection of various pollutants.This review focused on the research progress of aptasensors based on MOFs for detection of food and medicine homology contamination in the past few years,and provided a detailed comparison and analysis for detection of chemical pollutants(such as pesticide residues,heavy metal residues,mycotoxins,etc.)and microbial contamination in food and medicine homology substances.Besides,the development trend and possible challenges of MOFs aptasensors in detection of food and medicine homology substances in the future were discussed,which was anticipated to provide a reference for the development of new MOFs aptasensors.

Peyronie's disease (PD) is a disorder characterized by fibrous plaque formation in the penile tissue that leads to curvature and complications in advanced stages. In this study, we aimed to compare four injectable induction agents for the establishment of a robust rat model of PD: transforming growth factor-β1 (TGF-β1), fibrin, sodium tetradecyl sulfate (STS) combined with TGF-β1, and polidocanol (POL) combined with TGF-β1. The results showed that injection of TGF-β1 or fibrin into the tunica albuginea induced pathological endpoints without causing penile curvature. The STS + TGF-β1 combination resulted in both histological and morphological alterations, but with a high incidence of localized necrosis that led to animal death. The POL + TGF-β1 combination produced pathological changes and curvature comparable to STS + TGF-β1 and led to fewer complications. In conclusion, fibrin, STS + TGF-β1, and POL + TGF-β1 all induced PD with a certain degree of penile curvature and histological fibrosis in rats. The POL + TGF-β1 combination offered comparatively greater safety and clinical relevance and may have the greatest potential for PD research using model rats.

Tuberculosis(TB),a chronic infectious disease caused by infection with the Mycobacterium tuberculosis complex(MTBC),has re-emerged as the leading cause of death from a single infectious agent worldwide.Because of widespread use and mis-use of anti-tuberculosis drugs,the emergence of multidrug-resistant TB(MDR-TB)and extensively drug-resistant TB(XDR-TB)is increasing,thus posing a serious threat to global health.The current problem of drug resistance is a major prevention and treatment challenge;therefore,the search for new drug targets is urgently needed.In recent years,substantial progress has been made in re-search on anti-tuberculosis drug targets and novel therapeutic strategies.Herein,we summarize recent research progress in anti-tuberculosis drug targets,primarily cell wall synthesis,nucleic acid replication and transcription,and energy metabolism.We also provide an overview of research progress regarding two novel therapeutic strategies,to provide a theoretical basis and research ideas for the development of new clinical drugs.

Objective:To evaluate the changes of right atrial volume and function in patients with atrial septal defect（ASD）by four-dimensional ultrasound automatic quantitative technology，and to explore the predictive value and clinical significance for ASD with pulmonary arterial hypertension（PAH）.Methods:Sixty-one patients with ASD and 32 healthy volunteers（control group）who attended Central China Fuwai Hospital of Zhengzhou University，Fuwai Central China Cardiovascular Hospital from March 2023 to April 2024 were prospectively collected，and classified ASD patients into ASD without PAH group（non-PAH group， n=30）and ASD with PAH group（PAH group， n=31）according to whether or not they had PAH，and obtained right atrial reserve，ductal，systolic longitudinal and circumferential strains（RASr，RAScd，RASct，RASr-c，RAScd-c，RASct-c），right atrial minimal，maximal，and presystolic volumes（RAVmin，RAVmax，and RAVpreA），and calculated right atrial total，passive，and active ejection fraction（RAEF，RAPEF，RAAEF）. The ultrasound parameters and clinical data were compared between groups. Pearson's linear correlation was applied to analyse the correlation between the parameters（RASr，RAA，PASP，NT-proBNP）and mean pulmonary artery pressure（mPAP）. ROC curves were plotted and the area under the curve（AUC）was calculated to analyse the value of the four-dimensional strain parameters of the right atrium in independently and jointly predicting the combination of ASD with PAH. Results:①Compared with the control group，RAVmin，RAVmax，and RAVpreA were elevated in the non-PAH and PAH groups，and the absolute values of RAPEF and RAScd were decreased，whereas the absolute values of RAEF，RAAEF，RASr，RASct，RASr-c，and RASct-c were elevated in the non-PAH group，and decreased in the PAH group（all P<0.05）；compared with the non-PAH group，only RAVmin，RAVmax，and RAVpreA were elevated in the PAH group，and the rest of the above parameters were reduced，with statistically significant differences（all P<0.05）. ②The right atrial four-dimensional strain parameter RASr had the highest predictive value for ASD combined with PAH，with an AUC of 0.876，a specificity of 83.3%，and a sensitivity of 77.4%，respectively. ③RASr was negatively correlated with mPAP（ r=-0.591， P<0.001）and RAA，PASP and NT-proBNP were positively correlated with mPAP（ r=0.539，0.697，0.616；all P<0.001）. ④The predictive value of RASr combined with RAA，PASP，and NT-proBNP was superior for ASD combined with PAH（AUC=0.933）. Conclusions:Four-dimensional ultrasound automatic quantitative technology can effectively evaluate the changes of right atrial volume and function in patients with ASD. ASD patients without PAH have increased right atrial reserve and pump function，and decreased right atrial pipeline function. The right atrial function of ASD patients with PAH is significantly reduced，and the impairment is more severe. Among the right atrial four-dimensional strain parameters，RASr has the highest efficacy in predicting ASD combined with PAH. Moreover，the combination of RASr with RAA，PASP，and NT-proBNP has the best predictive efficacy for ASD combined with PAH，which holds significant clinical value.

Objective:To analyze the changes in the prevalence characteristics of multimorbidity among adolescents aged 13-18 in Inner Mongolia Autonomous Region from 2019 to 2022 and to explore the association between multimorbidity and moderate to high-intensity physical activity among them.Methods:A stratified random cluster sampling method was used to select students aged 13-18 in Inner Mongolia Autonomous Region every September from 2019 to 2022. Physical examinations, demographic characteristics, and depression-related surveys were conducted to analyze the multimorbidity of overweight, obesity, high blood pressure, myopia, spinal curvature abnormality, and depression. A logistic regression model was used to analyze the association between multimorbidity and moderate to high-intensity physical activity.Results:From 2019 to 2022, 70 972, 62 923, 80 254, and 78 288 study subjects were included, with the rates of multimorbidity being 56.4%, 55.4%, 57.2%, and 55.8%, respectively. The rates of multimorbidity remained relatively stable from 2019 to 2022 ( χ2=0.06, P=0.950). The incidence of multimorbidity among girls was significantly higher than that among boys ( P<0.001). The incidence of multimorbidity among urban students was significantly higher than that among suburban students ( P<0.001). The incidence of multimorbidity among high school students was higher than that among middle school students ( P<0.001). The top three multimorbidity combinations were myopia and overweight/obesity (26.4%), myopia and high blood pressure (24.4%), and myopia and depression (19.8%), while the least common combination was depression and spinal curvature abnormality (1.1%). The multimorbidity patterns showed no significant differences between years ( χ2=0.03, P=0.999). The multimorbidity status was significantly associated with the status of meeting the standard of moderate to high-intensity physical activity ( OR=0.83, 95% CI: 0.80-0.86). The association was stronger in boys ( OR=0.77, 95% CI: 0.73-0.81) compared with girls ( OR=0.90, 95% CI: 0.85-0.96), with a significant interaction term ( P<0.001). Conclusion:From 2019 to 2022, the incidence of multimorbidity among adolescents aged 13 to 18 in Inner Mongolia Autonomous Region is relatively high, mainly due to the co-occurrence of myopia and other health problems. Adequate physical activity is an important factor in reducing multimorbidity.
