To summarize the distribution characteristics of human papillomavirus(HPV) infection types in patients with cervical squamous intraepithelial lesion(SIL) and cervical cancer(CC), and to explore the impact of HPV vaccination, HPV infection types, and general clinical data on different grades of cervical lesions. Clinical data of women attending the gynecological colposcopy clinic of Shenzhen People's Hospital from January 2020 to December 2023 were retrospectively collected. Patients with HPV genotyping records and histopathologically diagnosed SIL or CC were included and divided into three groups based on pathological results: low-grade squamous intraepithelial lesion(LSIL) group, high-grade squamous intraepithelial lesion(HSIL) group, and CC group. The distribution of high-risk HPV subtypes was analyzed among the three groups, and multivariate Logistic regression was used to identify influencing factors for high-grade cervical lesions. A total of 4162 patients were included, comprising 4057 cervical SIL patients(3317 LSIL and 740 HSIL) and 105 CC patients. The overall mean age was(39.9±11.2) years. The HPV infection rate was 95.1%(3959/4162), and 25.0%(1040/4162) of patients had received HPV vaccination. Among high-risk HPV infections, HPV 52, HPV 16, HPV 58, and HPV 18 were the most common subtypes. HPV 52 had the highest infection rate in the LSIL group(27.6%), while HPV 16 was the most prevalent in the HSIL group(45.3%) and CC group(64.9%). Multivariate Logistic regression analysis showed that HPV vaccination( HPV infection is common in patients with SIL and CC, but the distribution of high-risk HPV subtypes varies among different grades of cervical lesions. It is recommended to strengthen cervical cancer screening and monitoring of key high-risk HPV infections in older and multiparous women in Shenzhen, and to continue promoting HPV vaccination.

Objective To explore risk factors of sodium-dependent glucose transporters 2 (SGLT2) inhibitor-associated euglycemic diabetic ketoacidosis (euDKA) and to construct a risk prediction model. Methods A retrospective analysis was performed on the clinical data of type 2 diabetes patients treated with SGLT2 inhibitors in Dongnan Hospital of Xiamen University from January 2020 to December 2023, including age, gender and course of diabetes. The risk factors of SGLT2 inhibitor-associated euDKA were analyzed by univariate analysis and multivariate Logistic regression, and a prediction model was established. According to the receiver's operating characteristic (ROC) curve, the area under the curve (AUC) and the optimal critical value of the prediction model were determined. The prediction model was subjected to both internal and external validation. Results A total of 119 patients with type 2 diabetes treated with SGLT2 inhibitors were included in this study. Among them, there were 98 cases without euDKA (non-euDKA group)and 21 cases with euDKA (euDKA group). Multivariate Logistic regression analysis showed the DKA history (OR=114.153), appetite or diet decreased three days before admission (OR=21.774), elevated neutrophil count (OR=2.056) and pre-hospital adjustment of hypoglycemic agents (OR=45.745) were independent factors to increase risks of euDKA associated with SGLT2 inhibitors (P<0.05). Surgical history before admission was an independent factor to reduce this risk (OR=0.007, P<0.05). By establishing the calculation formula of the prediction model = neutrophil count+6.571 (DKA history)−6.874 (surgical history before admission)+4.273 (appetite or diet decreased three days before admission)+5.302 (pre-hospital adjustment of hypoglycemic drugs), the ROC curve was drawn. The AUC of the ROC of the prediction model was 0.982 (95%CI: 0.961-1.000, P<0.001), with accuracy of 94.96%, sensitivity of 0.905, specificity of 0.959 and a critical value of 7.405. The AUC of ROC curve after the model’s ten-fold cross validation was 0.930. And the accuracy of the external validation of the prediction model was 85.29%. Conclusion The DKA history, appetite or diet decreased three days before admission, elevated neutrophil count and pre-hospital adjustment of hypoglycemic agents increased the risk of SGLT2 inhibitor-associated euDKA, while the surgical history before admission reduced this risk. The risk prediction model constructed on this basis could better predict the risk of SGLT2 inhibitor-associated euDKA.

OBJECTIVES:
To investigate the effect of age-friendly social and family care environment on the long-term care (LTC) services for the disabled elderly people.
METHODS:
A questionnaire-based survey was conducted among disabled elderly people in three cities of Zhejiang province from June to August 2022, involving 311 subjects from Ningbo city (LTC service insurance pilot site, insured group) and 542 subjects from Hangzhou and Quzhou cities (uninsured group). The service provisions, including ensuring daily activities, preventive healthcare, and satisfying spiritual comfort, were compared among the groups. The family friendly care environment was evaluated with the Family Function Scale and assistance of daily activities, financial support and emotional comfort. The social friendly care environment was measured with the revised WHO recommended age-friendly city environmental framework, including accessibility guarantee environment, information dissemination environment, social participant environment, and life security environment. After controlling for covariates such as sociodemographic, elderly care status, and health risk characteristics, the impact of environment on the effectiveness of service provision of LTC insurance was explored by multiple logistic regression analysis. The mediating and moderating effects were tested to explore the role of age-friendly care environment. A fixed effects model was used to test the service provision effects of LTC insurance policy.
RESULTS:
Disabled elderly with LTC insurance had a higher proportion of their preventive health care and spiritual comfort needs met. Additionally, a multifactorial analysis found a significant positive association between LTC insurance and meeting the spiritual comfort needs. Compared with insured group (Ningbo city), disabled elderly people in Hangzhou urban area (OR=0.45, 95%CI:0.27-0.74, P<0.01) and Quzhou rural area (OR=0.21, 95%CI:0.12-0.37, P<0.01) were more likely to feel unsatisfied with spiritual comfort. The results of mediation analysis showed that the scores of accessibility guarantee environment (OR=1.22, 95%CI:1.02-1.45, P<0.05), information dissemination environment (OR=1.19, 95%CI:1.02-1.39, P<0.05), and social participation environment (OR=1.40, 95%CI:1.17-1.67, P<0.01) in a socially friendly care environment were positively correlated with the satisfaction rate of mental comfort services. The results of the moderation effect analysis indicated that a socially friendly care environment (OR=1.46, 95%CI:1.16-1.84, P<0.01) could compensate for the difference in effectiveness between insured (Ningbo) and uninsured (Hangzhou and Quzhou) areas of LTC insurance. A fixed effect model confirmed the policy chain of LTC insurance policy-social friendly care environment-mental health service satisfaction.
CONCLUSIONS
The implementation of LTC insurance has improved service accessibility, making disabled elderly people feel "seen and valued", and generating psychological and spiritual satisfaction. Accelerating the establishment and improvement of the LTC insurance system requires systematic design, especially emphasizing the supportive role of a socially friendly care environment, and promoting it in urban and rural areas according to the local conditions.

This study aims to investigate the potential of oncolytic nanoparticles encapsulating Coxsackievirus A21 (CVA21) full-genome mRNA (CVA21@ONP) to resurrect CVA21 and induce apoptosis in host cells, as well as the antitumor immune effects of CVA21@ONP in immunocompetent tumor-bearing BALB/c mice. We used lipid nanoparticles (LNPs) to encapsulate CVA21 full-genome mRNA, thus preparing CVA21@ONP. The killing efficacy of CVA21@ONP was determined by the plaque assay and cell counting kit-8 (CCK-8), and the apoptosis in HT29 and CT26-iRFP cells was evaluated by flow cytometry. Mice were administrated with CVA21@ONP at high and low doses intratumorally, and the growth of tumors expressing infra-red fluorescent protein (iRFP) was monitored. Additionally, the types and changes of immune cells in the spleen were analyzed by flow cytometry. The results demonstrated that CVA21@ONP successfully resurrected CVA21 in both HT29 and U87MG cells. The plaque assay revealed robust killing effects of CVA21@ONP against both human and murine cell lines, and flow cytometry results showed increased early and late apoptotic cells. Notably, intratumoral detection revealed significantly down-regulated expression of iRFP in both high- and low-dose CVA21@ONP groups. Flow cytometry results further indicated that CVA21@ONP treatment effectively reduced the levels of immunosuppressive cells, including myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs), in the spleen, while enhancing T cell-dependent antitumor immune responses. These findings suggest that CVA21@ONP can replicate and survive extensively both in vitro and in vivo, activating the immune system of mice administrated with CVA21@ONP to target cells at the tumor site, thereby remodeling the tumor immune microenvironment and accelerating the suppression or even complete regression of tumors. The oncolytic performance of CVA21@ONP has been verified through intratumoral injection administration in this study, aimed at further exploring its therapeutic potential and promoting the development of the field of tumor treatment.

Epidemiological investigations and clinical studies have shown that inappropriate ambient temperatures (high and low temperatures) are the independent risk factors for ischemic stroke, but their underlying physiological mechanisms are not fully understood. This article systematically reviews the potential mechanisms by which inappropriate ambient temperatures promote the occurrence of ischemic stroke through multiple pathways, such as activating the sympathetic-renin-angiotensin system, inducing systemic inflammation and oxidative stress, damaging the integrity of the intestinal barrier and blood-brain barrier, and disrupting coagulation-fibrinolysis balance.

Objective:To investigate the methodological differences in the detection, the inflammatory markers and the pathogenic epidemiological characteristics of influenza A virus in clinical laboratories, in order to provide more diagnostic and epidemiological data for diagnosis and prevention for children with influenza A.Methods:A retrospective cross-sectional study was conducted to collect 96 731 patients with suspected influenza A from January 2016 to October 2024 in Nanyang City Center Hospital from the Clinical Laboratory Testing Information System, including 5 731 patients with confirmed influenza A, aged 5.2 (2.8, 43.7) years old. We analyzed the distribution of influenza A patients from age and mixed infections, the relationship between patient age and positive detection rate by restricted cubic spline (RCS), analyzed differences in testing methods used Kappa consistency testing and receiver operating characteristic (ROC) curves, established a model of inflammatory markers by logistic regression, as well as developed a prediction model and also the mutation of the hemagglutinin (HA) sequence of the influenza A subtype H3N2 virus using evolutionary tree analysis.Results:RCS analysis showed an inverted 'S' shaped non-linear relationship between the positive detection rate of influenza A and the age groups of the patients. Among the mixed infections, 1.43%(1 352/94 867) of the cases were combined with Mycoplasma pneumoniae infection. The Kappa values of reverse transcription PCR (RT-PCR) and serological indirect immunofluorescence assay (IFA) for detecting influenza A in nasopharyngeal swabs and alveolar lavage fluid in clinical laboratories were 0.632 and 0.809, respectively, and those of magnetic particle chemiluminescence assay were 0.614 and 0.668, respectively, and the area under curves in ROC curve of IFA and RT-PCR were 0.869 and 0.792, respectively. The inflammatory indexes were usually elevated in severe children compared with mild children. By binary logistic regression model analysis, neutrophil-to-lymphocyte ratio, D-dimer/fibrinogen and prognosis nutrition index were the risk factors and serum amyloid A/C reactive protein ratio was the protective factor for severe children with influenza A, and the OR values of the above factors were 1.760, 7.076, 1.045, and 0.719, respectively, and P<0.01. By the Bayesian Interdiction Criterion, the optimal seasonal autoregressive moving average mixed model for influenza A epidemics was ARIMA (1, 1, 1) (2, 1, 2) 12 with the highest prediction accuracy of 98.63%. The seven strains of H3N2 all belonged to the same isoforms, with nucleotide similarity of the HA gene ranging from 99.5% to 99.9%, and the glycosylation site, receptor-binding site, and the conserved amino acid residue Glycosylation sites, receptor binding sites and conserved amino acid residues remained unchanged. HA sequence analysis showed that the prevalent strains in Nanyang had undergone mutation to different degree compared with the vaccine strains. Conclusion:Scientific and rational testing and characteristic inflammatory markers in the clinical laboratory are of great clinical value in the diagnosis of children with severe influenza A. At the same time, the epidemiological monitoring of influenza A variants should be strengthened.

Objective:To explore the association between cardiometabolic multimorbidity(CMM), the number of cardiometabolic diseases(CMD)and mild cognitive impairment(MCI)among the older adults in urban communities.Methods:Based on the baseline data of the Hubei Memory and Aging Cohort Study(HMACS)from 2018 to 2023, CMM was defined as the coexistence of two or more CMDs(Type 2 diabetes, stroke and ischemic heart disease). Multivariate logistic regression was employed to examine the association between CMM, the number of CMDs and the prevalence of MCI, as well as subgroup heterogeneity.Results:This study included 6 113 urban participants aged ≥65 years(55.6% were female; mean age 71.9±5.7 years). The prevalence of MCI was 19.3%, with an increasing trend observed as the number of CMD increased(17.7%, 20.5%, 24.6%, 28.3%). After adjusting for all variables, a significant association was observed between CMM group and the prevalence of MCI( OR: 1.24, 95% CI: 1.01-1.52)compared with the non-CMM group.As the number of CMD increased, the prevalence of MCI increased( Ptrend=0.011), but the association was only significant in the group with two CMDs.Subgroup analyses revealed that in males( OR: 1.48, 95% CI: 1.10-2.00), those with more than 9 years of education( OR: 1.52, 95% CI: 1.15-2.02), and those with hypertension( OR: 1.33, 95% CI: 1.05-1.67), CMM was significantly associated with MCI, and the association with MCI increased significantly with the increase in the number of CMDs(all Pfor trend <0.05). Conclusions:Among urban community-dwelling older adults aged ≥65 years in China, CMM and the cumulative number of CMDs are significantly associated with an increase of MCI, particularly in males, those with higher education levels, and those with hypertension.In the future, the need for enhanced MCI screening for CMM patients should be strengthened, and targeted prevention and control of cognitive impairment should be implemented for high-risk populations.

AIM: To analyze the clinical outcomes of cyclosporine combined with lacrimal plug in the treatment of dry eye in patients with primary Sjögren's syndrome.METHODS: The clinical data of 60 patients(120 eyes)who were admitted to the ophthalmology department and rheumatology and immunology department of Baoding No.1 Central Hospital and were diagonosed with siogren's syndrome dry eye after multidisciplinary consultation from June 2022 to September 2023 were retrospectively analyzed. All the patients received regular treatment of primary Sjögren's syndrome, and they were divided into three groups according to treatment methods: A, B and C, with 20 cases(40 eyes)in each group. The group A received 0.3% sodium hyaluronate eyedrops, the group B received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops, and the group C received 0.3% sodium hyaluronate eyedrops plus 0.05% cyclosporine eyedrops combined with binocular lacrimal plugs. The ocular surface disease index(OSDI)score, conjunctival hyperemia score, tear film breakup time(BUT), tear meniscus height(TMH), corneal fluorescein staining(FL)score and tear secretion of the three groups of patients were compared before and at 4, 8 and 12 wk after treatment. The contents of inflammatory factors such as interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)in tears were detected before and at 12 wk after treatment.RESULTS: At 4, 8 and 12 wk after treatment, the scores of OSDI, conjunctival hyperemia score and FL in the three groups of patients were lower than those before treatment, and the BUT, TMH and tear secretion were higher than those before treatment(all P<0.001). The OSDI score of the group C was lower than that of the group A and B, and the group B was lower than the group A(all P<0.001). The BUT, TMH and tear secretion of the group C were higher than those of the group A and B, with the group B higher than the group A(all P<0.001). At 12 wk after treatment, the levels of IL-6, TNF-α and IL-1β in the tears of the three groups of patients were lower than those before treatment, with the group C lower than the group A and B, and the group B lower than the group A(all P<0.001). There was no statistical significant difference in the incidence of adverse reactions among the three groups of patients(P>0.05).CONCLUSION: The combined use of cyclosporine and lacrimal plug is safe and effective in improving the clinical symptoms of patients with moderate and severe dry eye, promoting the function of tear film and cornea, increasing tears secretion, and reducing the level of tear inflammatory factors.

Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals", it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure, qi and liquid imbalance, and kidney collaterals impairment, and it is proposed that the treatment principle is to nourish the sweat pore, regulate qi and fluid, and supplement the kidney and unblock the collaterals. In clinic, guided by sequential therapy and according to the different disease mechanism characteristics of the four stages, including early stage of the disease, hormone induction stage, hormone reduction stage, hormone maintenance stage, the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency, modified Zhenwu Decoction (真武汤) was applied to warm yang and drain water; for hormone induction stage with yin deficiency resulting in effulgent fire, modified Zhibai Dihuang Pill (知柏地黄丸) plus Erzhi Pill (二至丸) was used to enrich yin and reduce fire; for hormone reduction stage with qi and yin deficiency, modified Shenqi Dihuang Decoction (参芪地黄汤) was used to boost qi and nourish yin; for hormone maintenance stage, modified Shenqi Pill (肾气丸) was used to supplement yin and yang. Meanwhile, the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals, so as to providing ideas for clinical treatment.
