In vaccination,traditional vaccines are administered intramuscularly or subcutaneously,mainly inducing humoral immunity,with weak induction of mucosal immunity and insufficient protection against respiratory and gastrointestinal viruses.Current research has found that immuni-zation vaccines can effectively induce mucosal immunity through oral or nasal administration,but there is a lack of effective mucosal adjuvants,and there is an urgent need for the development of safe and effective new mucosal adjuvants.With the advancement of nano-adjuvant research,novel nanoparticles have attracted widespread attention due to their good mucosal adhesion,efficient an-tigen-loading ability,biocompatibility,and advantages in immune-enhancement,nano-size effect,tissue-targeting,and slow release of antigens,etc.,and are expected to be used as novel mucosal ad-juvants in the prevention and treatment of animal diseases.To date,significant progress has been made in research targeting mucosal adjuvants such as polymeric nanoparticles,inorganic nanoparti-cles,and liposomes.This paper reviews the application of nanomucosal adjuvants in animal vaccines and their mechanisms of action at home and abroad,and analyzes the physicochemical factors af-fecting the immune-enhancing effect of nanoparticle adjuvants,with a view to providing a reference for the development of novel mucosal adjuvants.

Objective:To analyze the changing trend of cervical cancer epidemiological characteristics and disease burden in cancer registration areas of Guangxi Zhuang Autonomous Region (Guangxi) from 2010 to 2017, and to provide scientific basis for the development of cervical cancer prevention and control strategies in Guangxi.Methods:Using descriptive analysis method, based on the incidence and death data of cervical cancer in the tumor registration areas of Guangxi from 2010 to 2017, Crude morbidity, crude mortality, age-standardized morbidity and mortality (referred to as the winning rate), disability adjusted life years (DALYs) rate and the annual percentage change (APC) and average annual percentage change (AAPC) of the above indicators were calculated, and stratified analysis was conducted for urban and rural areas and different age groups.Results:From 2010 to 2017, the crude incidence rate of cervical cancer in Guangxi showed a significant upward trend, rising from 10.31/10 5 in 2010 to 19.94/10 5 in 2017, with an average annual growth rate of 7.9% ( P＜0.05). However, after age standardization, the trend of the age-standardized incidence rate of cervical cancer was not statistically significant ( P＞0.05). During the same period, the crude mortality rate of cervical cancer increased from 2.69/10 5 to 6.21/10 5, with an average annual growth rate of 13.1% ( P＜0.05), and the trend of the age-standardized mortality rate was basically consistent with that of the crude mortality rate. The analysis of urban-rural differences showed that the growth rates of the crude incidence rate and crude mortality rate of cervical cancer in rural areas were higher than those in urban areas from 2010 to 2017 (AAPC incidence rate: 21.3% vs. 2.3%; AAPC mortality rate: 20.1% vs. 8.4%). The analysis of age differences showed that the crude incidence rate and crude mortality rate of cervical cancer in all age groups increased to varying degrees, among which the growth rate of the incidence rate (AAPC=16.2%, P＜0.05) and mortality rate (AAPC=14.7%, P＜0.05) of cervical cancer in women aged 65 and above was the fastest. In addition, the DALYs rate of cervical cancer in Guangxi increased from 50.6/10 5 in 2010 to 111.0/10 5 in 2017, with an average annual increase of 11.9% ( P＜0.05). The growth rate of the DALYs rate in rural areas was higher than that in urban areas, and the growth rate of the DALYs rate in the 50-59 age group was higher than those in other age groups. Conclusions:From 2010 to 2017, the incidence rate, mortality rate and DALYs rate of cervical cancer in Guangxi showed an upward trend. Comprehensive prevention and control measures for cervical cancer, such as improving the early diagnosis and treatment system, promoting the popularization of HPV vaccination and strengthening health education, should be taken to reduce the disease burden of cervical cancer.

Diabetic cataract, a prevalent ocular complication of diabetes mellitus, arises from a complex interplay of pathological mechanisms, with oxidative stress and glycation stress playing central roles. Autophagy, a critical cellular self-protection mechanism, sustains intracellular homeostasis by selectively degrading damaged organelles and misfolded proteins, thereby counteracting the detrimental effects of oxidative and glycation stress under hyperglycemic conditions. Emerging evidence indicates a synergistic interaction between glycation stress and oxidative stress, which may exacerbate autophagic dysfunction and accelerate the onset and progression of diabetic cataract. However, the precise molecular mechanisms underlying this relationship remain incompletely understood. This review systematically examines the regulatory role of autophagy inthe pathogenesis of diabetic cataract, with a particular focus on how autophagic impairment influences disease progression under the combined effects of glycation and oxidative stress. By elucidating these mechanisms, the paper aims to provide novel insights into molecular diagnostic approaches and targeted therapeutic strategies for diabetic cataract.

Objective To systematically evaluate the level of proteus mirabilis(PM)infection in patients with rheumatoid arthritis(RA)and to investigate its potential association with the development of RA.Methods Based on Meta-analysis of observational studies in epidemiology and preferred reporting items for systematic review and Meta-analysis guide,a comprehensive search of PubMed,Web of Science and Embase databases was conducted to screen relevant literature published up to December 2024 for studies comparing the levels of anti-PM antibodies between RA patients and healthy populations,and the quality of the included studies was assessed by using the Newcastle-Ottawa scale.Heterogeneity among studies was assessed by Q-test and I2-test,and accordingly,fixed-effects or random-effects models were selected,and the robustness of the results was assessed by sensitivity analyses,Begg's test,and clipping and patching method.Results Finally,18 eligible articles were included,involving 753 RA patients and 716 healthy controls.The total antibody levels[weighted mean difference(WMD)=0.86,95％CI:0.38-1.34,I2=98.3％,P=0.000]and IgA antibody levels(WMD=0.17,95％CI:0.06-0.28,I2=96.7％,P=0.000)of RA patients were higher than those of healthy controls,and subgroup analyses revealed significant heterogeneity among geographic regions and testing methods.Conclusion Prevention and treatment of PM infections may be a complementary strategy for RA management and provide evidence-based support for the"PM antigen-genitourinary tract mucosa-autoimmunity"pathology hypothesis.

OBJECTIVE To systematically evaluate the efficacy and safety of intrawound vancomycin powder for preventing surgical site infections in total knee and total hip arthroplasty. METHODS Computer retrieval of PubMed, Embase, Web of Science, the Cochrane Library, CNKI, Wanfang Database, Chinese Biomedical Literature Database, The clinical research about intrawound vancomycin in total knee arthroplasty(TKA) and total hip arthroplasty(THA) for the prevention of surgical site infections were screened. The quality of included studies was assessed using the Cochrane risk bias assessment tool and the Newcastle-Ottawa Scale. Meta-analysis was performed using RevMan 5.4 software. RESULTS Finally, 20 literature were included, including 1 prospective randomized controlled trial, 2 prospective cohort study, and 17 retrospective cohort study, with a total of 34900 patients. Meta-analysis showed that interventional group had a decreased tolal rate of prosthetic joint infection(PJI)[OR=0.44, 95%CI(0.35−0.56), P<0.000 01] and superficial infection[OR=0.27, 95%CI(0.19−0.41), P<0.000 01]compared with control group. Subgroup analysis showed that TKA and THA, primary and revision patients who received intrawound vancomycin had lower rates of PJI, the differences were statistical significance(P<0.05). Meta-analysis of 11 studies reported adverse reaction suggested that the total rate of adverse reactions in the intervention group(7.68%) was higher than that in the control group(5.68%) with significant differences[OR=1.47, 95%CI(1.14−1.89), P=0.003)]. CONCLUSION The current literature suggests that intrawound vancomycin can decrease the rate of PJI and superficial infection in primary and revision TKA and THA , however, it may increase risk of aseptic wound complications and other adverse reaction.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective: To understand the relationship between family environment and depressive symptoms among adolescent, and to provide a reference for adolescent mental health promotion and intervention. Methods: From September to December in 2021, a questionnaire survey on family environment and depressive symptoms was conducted among 8 102 middle school students by random cluster sampling method in Shanghai, Urumqi, Changsha and Kunming. The Chi square test was used to compare the depression status of students in different family environments. Multivariate Logistic regression analysis was used to explore the relationship between family environment and depressive symptoms. Results: The detection rates of possible depression, likely depression and severe depression in adolescents were 11.2%, 5.9% and 8.4%, respectively. There were significant differences in the detection rate of depression by gender, academic period, urban and rural areas, family forms and only child statu( χ 2=87.60, 27.19, 6.65, 45.59, 4.78, P <0.05). Logistic regression analysis showed that adolescents in single parent families ( OR =1.45) and reorganized families( OR =1.69) were positively correlated with the occurrence of depressive symptoms compared with those in nuclear families( P <0.01). Conclusion Compared with nuclear families, the risks of adolescent depressive symptoms in single parent families and reorganized families are higher. Attention should be paid to the mental health education of teenagers from single parents and reorganized families to ensure the development of their physical and mental health.
