Microbial infections are a prevalent challenge in the prevention and treatment of oral diseases. Antibiotic therapy faces clinical limitations due to its single-target mechanism and tendency to induce resistance with repeated use, necessitating novel antibacterial strategies. Stimuli-responsive antibacterial materials, whose antimicrobial activity can be modulated by external stimuli, offer advantages such as remote controllability, potential for localized precision treatment, and a reduced risk of inducing resistance. Among these materials, mechanical force-triggered piezoelectric materials exhibit significant antibacterial activity in the biomedical field owing to their unique piezoelectric effect, excellent stability, and good biocompatibility. Research has shown that piezoelectric materials can convert mechanical energy into electrical energy in response to external forces, which enables antibacterial effects without requiring an external power source. The underlying mechanisms primarily include direct electric field effects, generation of reactive oxygen species, and immune modulation. Preliminary applications in treating oral infections (e.g., dental caries, periodontitis, and peri-implantitis) have confirmed their stability and biocompatibility, establishing a foundation for clinical translation. However, long-term efficacy and biosafety in the complex oral microenvironment require further validation. Future research should focus on optimizing material preparation protocols to enhance antibacterial efficacy and stability, further investigating the underlying antimicrobial mechanisms, and systematically evaluating their therapeutic outcomes and safety profiles across various types of oral infections. This review summarizes the antibacterial effects, mechanisms, stability, safety, and research progress of piezoelectric materials in the stomatologic field, aiming to provide new insights for further research and application in this area.

Objective:This aims to investigate the diagnostic and evaluative value of MRI for lymphatic malformations in the head, neck, and facial regions of children. Methods:A retrospective analysis was conducted on the MRI imaging data of 31 cases of head, neck, and facial lymphatic malformations in children admitted to the Department of Otolaryngology, Head and Neck Surgery, Children's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, from January 2022 to January 2024. Results:The MRI images of this group of cases primarily displayed irregular morphology(80.6%, 25/31), thin-walled cysts(80.6%, 25/31), and compression of surrounding tissues. The boundaries were clear(100%, 31/31), with characteristics of invasive and drill-like growth(93.5%). The cyst walls or internal septa exhibited high signal intensity on T1WI, low signal intensity on T2WI, and mild to moderate enhancement(100%). The contents of the cysts showed low signal intensity on T1WI, high signal intensity on T2WI, and no enhancement(35.5%, 11/31). Mixed signals with varying degrees of enhancement were observed in 20 cases(64.5%). There were 29 cases of multilocular cysts(93.5%, 29/31), and 11 cases of fluid-fluid levels(35.5%). The MRI diagnostic accuracy for this group of cases was 100%. Conclusion:Lymphatic Malformations of head, neck and facial region in children have very characteristic features on MRI, such as typical thin wall, clear boundaries, irregular shapes, invasive growth, no enhancement, multilocular cystic masses, fluid-fluid level, etc. Furthermore, it is more appropriate for children with lymphatic malformations owing to its non-radiation and non-invasive benefits. Diagnosing lymphatic malformations in the head, neck, and facial region in children should begin with this.

To date, most studies support the combination therapy of cognitive behavioral therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs) compared to monotherapy in adolescents, adults, and older adults with major depressive disorder. However, the results were inconsistent. This article reviews the efficacy and influencing factors of CBT combined with SSRIs in the treatment of adolescents, adults, and elderly patients with major depressive disorder. It is suggested that the efficacy of this combination therapy is related to the severity of depression, cognitive function, education level, responsiveness to treatment, duration of treatment and end time of treatment, and the shortcomings and prospects of the previous research are put forward.

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide, causing a significant socioeconomic burden. This article reviews the effects of influenza vaccination on COPD and finds that influenza vaccine can significantly reduce the risk of influenza infection, reduce the number of acute exacerbations, and reduce the hospitalization rate in patients with COPD. The vaccine has a favorable safety profile and significant economic benefits, which can reduce medical costs. Currently, influenza vaccination mainly faces challenges such as insufficient patient awareness, insufficient support from the medical system, and socio-cultural and economic factors. Efforts should be focused on reducing the acute exacerbation of COPD patients and providing a scientific basis for the prevention and management of COPD patients.
6.Prevention and treatment of severe fever with thrombocytopenia syndrome: Progress and challenges
Chinese Journal of Experimental and Clinical Virology 2025;39(2):133-135
Severe fever with thrombocytopenia syndrome (SFTS), caused by caused by Bandavirus dabieense(formerly known as severe fever with thrombocytopenia syndrome Bunyavirus, SFTSV), is a tick-borne emerging infectious disease first identified in China in 2009. Since its discovery, the epidemic has expanded to 27 provinces nationwide. This article systematically reviews the epidemiological evolution, clinical treatment and prevention challenges of SFTS in China over the past 15 years. By integrating international case studies such as Nipah virus and monkeypox, we propose strategies including adopting orphan drug development incentive policies, standardizing clinical protocols, and implementing the " One Health" concept. These recommendations aim to provide actionable pathways for SFTS prevention, treatment, and reduction of disease burden.

Objective:To explore the association between greenspace morphology and the risk of severe fever with thrombocytopenia syndrome (SFTS) in Shandong Province.Methods:The SFTS cases data and land use data in Shandong province from 2018 to 2022 were collected, 6 landscape indices were calculated through Fragstats 4.2 software, and a negative binomial regression model was used to quantitatively evaluate the effect. Meteorological and socioeconomic factors during the same period were controlled as covariates. Subgroup analysis were conducted by age, gender and occupation. The percentage of relative risk[(RR-1)×100%] with 95% confidence interval (95% CI) was used as effect estimates. Results:There was a significant association between greenspace morphology and the risk of SFTS. Every 1% increase in the percentage, the mean area, fragmentation, aggregation, connectedness, and complexity of the shape of greenspace will lead to an increase in the risk of SFTS by 4.28% (95% CI: 2.88%-5.68%), 3.56% (95% CI: 1.06%-6.12%), 2.43% (95% CI: 1.38%-3.61%), 2.22% (95% CI: 1.39%-3.11%), 0.41% (95% CI: 0.26%-0.56%), 0.26% (95% CI: 0.10%-0.41%), respectively. There were statistically significant differences in the association between greenspace morphology and the risk of SFTS among different age and occupational subgroups. The elderly and farmers were the more susceptible to the changes in the percentage of greenspace and the complexity of the shape of greenspace. Conclusions:Greenspace morphology is related to the risk of SFTS. The elderly and farmers are vulnerable populations.

Objective: To compare the changes in the concentration of relevant growth factors released from platelet-rich plasma (PRP) stored at -80℃ by cryopreservation and at 4℃ by refrigerated lyophilization over 2 years, aiming to provide a theoretical basis for prolonging PRP storage duration. Methods: PRP (n=15) was separated using a blood cell separator and stored under -80℃ cryopreservation (F-PRP group) and 4℃ refrigerated freeze-drying conditions (FD-PRP group). The contents of growth factors (PDGF-AA, PDGF-BB, EGF, TGF-β1, and VEGF) in both groups were measured by ELISA at 1, 3, 6, 9, 12 and 24 months. Results: PDGF-AA and VEGF maintained good stability in both groups for up to 24 months. PDGF-BB and TGF-β1 showed high stability in the first 12 months but their stability decreased gradually from 12th to 24th months. EGF demonstrated good stability in the first 6 months, and its stability gradually decreased from the 9th to 24th months. Comparing the F-PRP and FD-PRP groups, the concentrations of the five growth factors in the FD-PRP group were either not statistically different or higher than those in the F-PRP group at all time points. Specifically, the concentrations of EGF were significantly higher in the FD-PRP group at all time points. Conclusion: Both -80℃ freezing and 4℃ freeze-drying enable long-term preservation of PRP. Freeze-drying imposes less stringent storage requirements and facilitates growth factor compared to frozen storage.

Objective To investigate the correlation between different forms of serum vitamin D levels and liver fibrosis in patients with metabolic dysfunction-associated fatty liver disease (MAFLD). Methods Data from the National Health and Nutrition Examination Survey in 2021–2023 were analyzed. Logistic regression models were used to evaluate the relationship between serum total vitamin D, 25(OH)D3 levels, and liver fibrosis in the MAFLD patients. Results A total of 2 628 patients were included. There were significant differences between MAFLD patients with liver fibrosis and those without fibrosis in age, smoking history, waist circumference, body mass index, high-density lipoprotein cholesterol, total cholesterol, fasting plasma glucose, hypertension history, vitamin D, and 25(OH)D3 levels (P<0.05). Logistic regression analysis revealed that compared to the low total serum vitamin D group (11.2-61.8 nmol/L), MAFLD patients with high total vitamin D levels (89.1 nmol/L<vitamin D≤290 nmol/L) exhibited a 22% reduced risk of liver fibrosis (OR=0.78, 95%CI 0.64-0.94, P=0.015). Similarly, compared to the low 25(OH)D3 group (4.1-57.0 nmol/L), those with high 25(OH)D3 level [84.7 nmol/L<25(OH)D3≤288 nmol/L] showed a 23% lower risk of liver fibrosis (OR=0.77, 95%CI 0.62-0.95, P=0.021). After adjusting for covariates, high total vitamin D levels remained significantly associated with reduced liver fibrosis risk (OR=0.63, 95%CI 0.42-0.94, P=0.036). Conclusions Elevated serum total vitamin D and 25(OH)D3 levels are protective factors against early liver fibrosis in MAFLD patients.
