Adenoviruses are the main pathogens causing acute respiratory tract infection in infants and young children,and adenovirus types 3 and 7 infections often develop into severe pneumonia,which seriously threatens chil-dren's health and affects their quality of life.Exosomes are extracellular vesicles that possess a phospholipid bilayer struc-ture.Exosomes can be secreted and synthesized by various cells and can carry a variety of bioactive substances,such as nucleic acids and proteins.The occurrence and release of exosomes are closely related to the physiological functions of the body's cells.In recent years,studies have shown that exosomes released by patients with adenovirus infection play crucial roles in transmission and immune response activation against the virus.Therefore,in-depth research on exosomes and ade-noviruses provides new directions for the diagnosis,treatment,and clinical drug development of paediatric adenovirus pneumonia.

Objective:To investigate the longitudinal association between the Chinese Visceral Adiposity Index(CVAI) and cardiovascular disease(CVD) risk in middle-aged and elderly individuals with abnormal glucose metabolism.Methods:A total of 3 662 individuals with abnormal glucose metabolism from the China Health and Retirement Longitudinal Study(CHARLS) database were included. The cumulative incidence of CVD events was estimated using Kaplan-Meier curves. Cox proportional hazards models were used to assess the association between CVAI and CVD events, and a multivariate-adjusted restricted cubic spline(RCS) curve was fitted to test the dose-response relationship between CVAI and incident CVD events. Subgroup analyses were also conducted to explore potential effect modifiers. Results:During the follow-up, 844 participants experienced CVD events. In the fully adjusted model, every interquartile range( IQR) increment in CVAI was significantly associated with an increased risk of CVD events, with a hazard ratio( HR)[95% confidence interval( CI)] of 1.22(1.11-1.35). Compared to the first quartile( Q1) of CVAI, the HRs(95% CI) for CVD event incidence in Q2- Q4 were 1.22(0.98-1.52), 1.29(1.05-1.61), and 1.51(1.22-1.88), respectively. Subgroup analysis indicated a significant interaction effect between CVAI and age on the risk of CVD events in individuals with abnormal glucose metabolism( P for interaction <0.05). No significant interactions were found for gender, body mass index(BMI), waist circumference(WC), smoking, alcohol consumption, and hypertension(all P for interaction >0.05). Furthermore, the multivariate-adjusted RCS regression revealed a significant dose-response relationship between CVAI and CVD events( P<0.001, P for nonlinearity=0.568). Conclusions:In middle-aged and elderly individuals with abnormal glucose metabolism, CVAI is independently associated with an increased risk of incident CVD events and may serve as a reliable surrogate marker for assessing visceral adiposity in this population. Regular monitoring of CVAI should be considered for integration into routine clinical practice to improve CVD prevention in individuals with abnormal glucose metabolism.

Being an emerging medical imaging modality,wearable ultrasound technology has advantages such as higher portability,wearability and capability for prolonged continuous monitoring,being applied into cardiovascular system and oncology,etc.,and demonstrated significant potential.However,the development wearable ultrasound technology still faces challenges,including issues related to image quality,data processing and user experience.The recent advancements in wearable ultrasound technology were reviewed in this article.

Peritoneal metastasis is a common form of distant metastasis in patients with colorectal cancer, and it is typically associated with a poor prognosis. The development of peritoneal metastasis involves complex molecular mechanisms and multifactorial regulation of the tumor microenvironment. Due to the presence of the blood-peritoneal barrier, only a small amount of systemic medication reaches the peritoneal cavity, resulting in limited efficacy against peritoneal metastasis. Intraperitoneal administration shows significant therapeutic advantages as it can directly target the tumor microenvironment, maintain high local drug concentrations, and reduce systemic toxicity. Intraperitoneal chemotherapy, especially hyperthermic intraperitoneal chemotherapy, has become a cornerstone therapeutic strategy in the clinical treatment of peritoneal metastasis. When selecting chemotherapy drugs and drug combinations, pharmacokinetic properties, efficacy, and safety must be comprehensively considered to optimize the treatment outcomes. In addition, the unique microenvironment of the peritoneal cavity provides new treatment approaches for biological treatment strategies, including antitoxins, vaccines, immune checkpoint inhibitors, etc. Techniques such as pressurized intraperitoneal aerosol chemotherapy and novel drug delivery systems demonstrate potential for enhanced efficacy, offering promising alternatives to improve patient outcomes. This article will review peritoneal barrier characteristics, intraperitoneal drug transport, intraperitoneal chemotherapy, and intraperitoneal biological therapies, thereby establishing a theoretical framework for precision therapy in colorectal cancer peritoneal metastasis.

Objective To explore the value of intensity ratio(IR)of lesion to non-tumor liver parenchyma on contrast-enhanced ultrasound(CEUS)Kupffer phase for differentiating hepatocellular carcinoma(HCC)and intrahepatic cholangiocarcinoma(IHC)/metastatic liver carcinoma.Methods Totally 54 patients with HCC(HCC group),30 with IHC and 51 with liver metastatic carcinoma(non-HCC group)diagnosed by pathology were retrospectively enrolled.Quantitative parameters derived from CEUS time-intensity curves,including peak intensity(PI),time to peak(TTP),wash-in area under the curve(WiAUC),wash-out area under the curve(WoAUC),wash-in and wash-out area under the curve(WiWoAUC)of lesion in vascular phase and IR of lesion to non-tumor liver parenchyma in Kupffer phase were compared between groups,and a combined diagnostic model was established based on parameters being significantly different between groups using binary logistic regression analysis.Receiver operating characteristic(ROC)curves were plotted,and the area under the curves(AUC)were calculated to evaluate the efficacy of each CEUS parameter alone and the combined model for differentiating HCC and IHC/liver metastatic carcinoma.Results In HCC group,PI,WoAUC and WiWoAUC were all higher(all P＜0.001),while IR was significantly lower than those in non-HCC group(P＜0.001).The AUC of PI,WoAUC,WiWoAUC and IR for differentiating HCC and IHC/metastatic liver carcinoma was 0.673,0.741,0.738 and 0.736,respectively,all lower than that of combined model(0.862,all P＜0.05).Conclusion IR of lesion to non-tumor liver parenchyma on CEUS Kupffer phase could be used to differentiate HCC and IHC/metastatic liver carcinoma.Combining with quantitative parameters on CEUS vascular phase could improve differentiating efficiency.
