Objective: To evaluate the incremental vaccine effectiveness (VE) of two dose of the mumps containing vaccine (MuCV) in chidren, so as to provide a basis for optimizing mumps immunization strategies. Methods: A 1∶2 frequency matched case-control study was conducted by using reported mumps cases in childcare centers or schools from Lu an, Hefei, Ma anshan and Huainan cities of Anhui Province from September 1, 2023 to June 30, 2024, as a case group(383 cases). And healthy children in the same classroom were selected as a control group(766 cases). The MuCV immunization histories of participants were collected to estimate the incremental VE of the second dose of MuCV against mumps. Group comparisons were performed using the Chi square test or t-test. For matched case-control pairs, the Cox regression model was employed to calculate the odds ratio (OR) with 95% confidence interval (CI) for two dose MuCV vaccination and to estimate the incremental vaccine effectiveness (VE). Results: There were no statistically significant differences between the case and control groups regarding gender, age, dosage of MuCV vaccination and the time interval since the last dose vaccination( χ 2/t=0.05, 0.20, 0.94, -0.02, P >0.05). The proportions of the case and control groups vaccinated with two doses of MuCV were 26.63% and 29.37%, respectively, and the overall incremental VE of the second dose of MuCV was 40.73% (95% CI=3.03%-63.77%, P <0.05). Subgroup analyses revealed that the incremental VE for children with a period of ≥1 year between the two doses of MuCV was 54.13% (95% CI=1.90%-78.56%, P <0.05), while for children with a period of <1 year, it was 30.63% (95% CI=-28.59%-62.58%, P >0.05). The incremental VE of the second dose of MuCV was 30.36% (95% CI=-25.95%-61.50%, P >0.05) in kindergarten children and 66.73% (95% CI=14.92%-86.99%, P <0.05) in elementary and secondary school students. The incremental VE was 28.78% (95% CI=-27.46%-60.21%, P >0.05) within five years of the last dose of MuCV vaccination and 66.07% (95% CI=-41.56%-91.87%, P >0.05) for vaccinations administered beyond five years. Conclusions The second dose of MuCV may offer additional protection for children; however, extending the interval between two dose of MuCV (<1 year) has shown limited incremental protective effects. Therefore, it is crucial to consider optimizing current immunization strategies for mumps.

Colorectal cancer(CRC) is one of the most common malignant tumors worldwide, primarily originating from recurrent inflammatory bowel disease(IBD). Therefore, blocking the inflammation-cancer transformation in the colon has become a focus in the early prevention and treatment of CRC. The inflammation-cancer transformation in the colon involves multiple types of cells and complex pathological processes, including inflammatory responses and tumorigenesis. In this complex pathological process, immune cells(including non-specific and specific immune cells) and non-immune cells(such as tumor cells and fibroblasts) interact with each other, collectively promoting the progression of the disease. In traditional Chinese medicine(TCM), inflammation-cancer transformation in the colon belongs to the categories of dysentery and diarrhea, with the main pathogenesis being cold and heat in complexity. This paper first elaborates on the complex molecular mechanisms involved in the inflammation-cancer transformation process in the colon from the perspectives of inflammation, cancer, and their mutual influences. Subsequently, by comparing the pathogenic characteristics and clinical manifestations between inflammation-cancer transformation and the TCM pathogenesis of cold and heat in complexity, this paper explores the intrinsic connections between the two. Furthermore, based on the correlation between inflammation-cancer transformation in the colon and the TCM pathogenesis, this paper delves into the importance of the interaction between inflammation and cancer. Finally, it summarizes and discusses the clinical and basic research progress in the TCM intervention in the inflammation-cancer transformation process, providing a theoretical basis and treatment strategy for the treatment of CRC with integrated traditional Chinese and Western medicine.

Objective:To investigate the current status of scientific fitness literacy (SFL) and its influencing factors among Chinese adults aged 20-59 years.Methods:Totally 63 338 adults aged 20-59 years in the status of national fitness activities in 2020 from 1 January to 31 March 2020 were selected as the subjects, and they were divided into four age groups, namely, the 20-29 age group, the 30-39 age group, the 40-49 age group and the 50-59 age group. Data were analyzed by SPSS 29.0.Comparative analyses for age, gender, urban-rural difference were carried out by applying non-parametric tests, and multiple regression models were applied to find the influencing factors of SFL.Results:The SFL score of Chinese adults aged 20-59 years was 53.40 (41.67, 63.73), and the scores of cognition, attitude, ability and skills, behavior and habits sub-dimensions were 86.11 (72.22, 100.00), 62.96 (50.62, 75.31), 27.78 (11.11, 44.44) and 33.33 (11.11, 55.56), respectively. The SFL and the four sub-dimensions were demonstrated to have higher scores for males than females, and higher scores for adults in urban area than those in rural area(all P<0.01). The multiple regression results showed that regular exercise at a fitness facility (20-29 age group: β=0.321, t=5.940, P<0.01; 30-39 age group: β=0.187, t=2.937, P<0.01; 40-49 age group: β=0.230, t=3.988, P<0.01; 50-59 age group: β=0.415, t=5.671, P<0.01) was the Chinese adults' common influence factor on SFL.Motivation, evaluation by those around them, experience from exercising, and convenience and atmosphere of exercising were the main influence factors in the 20-29 and 30-39 age groups(all P<0.05).Comfort level of fitness venue, convenience, safety, and support of fitness place were the main influence factors in adults aged 40-59 years(all P<0.05). Conclusions:Chinese adults aged 20-59 years old have high SFL awareness scores, but low overall SFL scores. Surrounding people's evaluation, experience in exercise, comfort level of fitness place, convenience, safety and fitness policy support are the influential factors of scientific fitness literacy.

Objective:To study the differentially expressed genes in chronic periodontitis (CP) and to explore the correlation with disease severity.Methods:Gene expression profile data associated with CP were screened in the Gene Expression Omnibus (GEO) database and analyzed with GEO2R online software to create volcano maps. Kyoto Encyclopedia of Genes and Genomes (KEEG) and Gene Ontology (GO) analyses were performed on the screened CP-associated differentially expressed genes to predict their possible functions and signaling pathways. The protein-protein interaction database (STRING) was used to analyze the interaction relationships between the encoded proteins of the screened CP-related differentially expressed genes. Cytohubba software was used to identify key genes in the signaling pathway. One120 CP patients and 40 healthy controls were selected. The screened CP-related genes were validated by the real-time polymerase chain reaction (q-PCR) method.Results:A total of 1 151 CP differentially expressed genes that met the requirements were screened. These genes were mainly enriched in the GO pathway for positive regulation of granulocyte differentiation, helper T-cell differentiation, leukocyte aggregation, regulation of acute inflammatory response, chemokine-mediated and endoplasmic reticulum unfolded protein response, as well as in the KEGG pathway for NFB pathway, chemokine pathway, cytokine receptor interaction, leukocyte transendothelial migration pathway, B-cell receptor pathway, Toll-like receptor pathway, etc. The protein-protein interaction network was constructed using the screened CP-related differentially expressed genes, which included 78 nodes and 496 links, with a mean aggregation coefficient and mean connectivity of 0.69 and 12.7, respectively. Cytohubba analysis showed that Sell was a key gene in the signaling pathway, and its relative expression levels in the gingival fluids of the three CP groups with different degrees(1.14±0.46, 0.86±0.41, 0.52±0.46) was significantly lower than that of the control group (1.50±0.65) (all P<0.05). The area under the ROC curve (AUC) of subjects diagnosed with CP using Sell expression levels in gingival fluid was 0.79 (95% CI: 0.71 to 0.86). The AUC values were greater than 0.65 at 95% CI when Sell was used as a biological marker to evaluate the severity of CP. Conclusions:CP-related differentially expressed genes are mainly enriched in the number of pathways associated with the inflammatory response of periodontitis. The expression levels of Sell genes were significantly reduced in the gingival sulcus fluid of CP patients and correlated with the severity of the disease. The Sell genes are expected to be a biomarker for CP grading.

Objective To understand the real prevalence of Clonorchis sinensis infections in the freshwater fish in mainland China, so as to provide insights into clonorchiasis control and detection of freshwater fish. Methods All literatures reporting the prevalence of C. sinensis infections in the freshwater fish, the second intermediate host of the parasite, were jointly retrieved in Chinese and English electronic databases from January 1, 2010 to December 31, 2020, including Wanfang Data, CNKI, PubMed, Web of Science, Embase and Cochrane Library. All studies were screened based on inclusion and exclusion criteria, and the quality of all enrolled literatures was evaluated. The pooled prevalence of C. sinensis infections in freshwater fish and its 95% confidence interval (CI) were estimated using the software Stata version 15.0, and subgroup analyses were performed to investigate the region-, season- and sample source-specific pooled prevalence of C. sinensis infections in freshwater fish. In addition, the sensitivity and publication bias of all included studies were analyzed. Results A total of 40 eligible literatures were included in this study, including 37 Chinese literatures and 3 English literatures, and there were 10 high-quality literatures, 27 moderate-quality literatures and 3 low-quality literatures. A total of 53 species containing 37 959 freshwater fish were reported in these 40 studies, and 73.58% (39/53) of freshwater fish species were identified with C. sinensis infections. Meta-analysis showed 23.5% [95% CI: (0.19, 0.28)] pooled prevalence of C. sinensis infections in freshwater fish in mainland China, and subgroup analyses higher prevalence of C. sinensis infections in freshwater fish in northeastern China [35.7%, 95% CI: (0.22, 0.50)] than in central [25.9%, 95% CI: (0.04, 0.48)] and southern China [20.6%, 95% CI: (0.09, 0.32)], higher prevalence of C. sinensis infections in freshwater fish sampled in spring [44.1%, 95% CI: (0.35, 0.53)] than in autumn [6.7%, 95% CI: (0.05, 0.08)] and summer [3.3%, 95% CI: (−0.01, 0.07)], and higher prevalence of C. sinensis infections in freshwater fish sampled from natural water [25.2%, 95% CI: (0.17, 0.33)] than from retail trades [22.2%, 95% CI: (0.17, 0.28)] and breeding chain [12.3%, 95% CI: (0.03, 0.22)]. However, all included studies had a publication bias with a low sensitivity. Conclusions The prevalence of C. sinensis infections is high in freshwater fish in mainland China, and there are still challenges for clonorchiasis control. Reinforcement of health education, diagnostics development and food safety supervision is recommended in future clonorchiasis control programs.

Objective: To investigate the effect of insertion technique and electrode array type on the insertion force of electrode array, and to provide a basis for further optimizing electrode design and facilitating mini-invasive electrode insertion. Methods: Three types of electrode array from Nurotron (Standard Electrode, Slim-medium Electrode, Slim-long Electrode) were studied. from July 2019 to December 2019. These electrode arrays were inserted into the phantom models of the cochlea, manually or robot-assisted(medium speed and low speed). The real-time force during electrode array insertion was recorded by ATI Nano 17 Ti sensors and was analyzed by accessory software. Origin 2020b software was used for statistical processing. Results: The insertion force of all electrode arrays progressively increased with the insertion depth. With the manual technique, the peak force of slim-medium electrode insertion was significantly smaller than that of the standard electrode insertion((71.0±16.6) mN vs (140.9±52.7) mN, Z=3.683, P<0.01), and the peak force of the slim-long electrode insertion was between the peak force of standard electrode and slim-medium electrode(P>0.05). No difference was found in the force variation of insertion among the three electrodes(P>0.05). With medium-speed and low-speed robotic assistance, the peak force characteristics of three electrodes were similar to those with the manual technique, but the force variation of standard electrode insertion ((83.9±9.7) mN/s) at medium speed was significantly larger than that of the slim-long electrode insertion ((69.2±4.0)mN/s), and the force variation of the standard electrode insertion at low speed was significantly greater than the other two electrodes. For the same electrode, robot-assisted insertion presented significantly lower peak force and force variation than manual insertion for each type of electrode array. But there was no difference in the peak force and force variation between two-speed levels of robot assistance (P>0.05). Conclusions: The insertion force of the electrode array will be lower when a slim electrode array or robot technique is applied. Long electrode array might make manual insertion difficult or less precise. Robot assistance has advantage on force control during electrode array insertion.

Objective:To explore the clinical value of autoantibodies in patients with liver disease.Methods:We retrospectively analyzed the data of 1 495 outpatients or inpatients with liver disease in Beijing Ditan Hospital of Capital Medical University from August 2020 to April 2021. Indirect immunofluorescence and Western blot were used to detect antinuclear antibody (ANA) and antinuclear antibodies (ANAs).Results:ANA and ANAs were positive in patients with liver diseases of various etiologies. Among 1 495 patients with liver disease, 494 cases were ANA positive, the positive rate was 33.04%; 573 cases were positive for ANAs, the positive rate was 38.33%. The positive rate of ANA in the immune liver disease group (63.37%) was higher than that in the viral, alcoholic, fatty liver, confounding factors and other liver disease groups, and the difference was statistically significant ( P<0.01). The ANA positive rate between the viral, alcoholic, fatty liver, and confounding factor groups was statistically significant ( χ2=19.823, P<0.01), the positive rate of ANAs in the immune liver disease group (80.23%) was higher than that in other liver disease groups, and the difference was statistically significant ( P<0.05). The antibody titer of immune liver disease group was mainly 1∶1000, and other liver disease etiology groups was mainly 1∶100. The two most common fluorescent karyotypes in liver disease groups of different etiologies are cytoplasmic and nuclear granular types. The most common specific antibody in the immune liver disease group was anti-mitochondrial antibody type 2 (anti-AMA-M2) antibody, the most common anti-Ro-52 antibody in viral, drug-induced, complex etiology, and other etiological groups, and the most common anti-SSA antibody in alcoholic liver disease. Anti-SSA antibody (17.44%), anti-SSB antibody (9.30%), anti-CENP-B antibody (22.09%), anti-Ro-52 antibody (41.28%), anti-AMA-M2 antibody (51.74%) were positive in immune liver disease group, The rate was higher than that of other liver disease etiology groups, and the difference was statistically significant ( P<0.01). When the ANA fluorescence karyotype is nuclear granule type, the positive rate of anti-CENP-B antibody, anti-Ro-52 antibody, and anti-AMA-M2 antibody in the immune liver disease group was higher than that in the viral liver disease group ( P<0.01), The positive rate of anti-Ro-52 antibody was higher than that of drug-induced liver disease group ( P<0.05). Conclusions:The ANA titer of autoimmune liver disease was mainly (1∶1 000). ANAs were mainly positive for anti-SSA antibody, anti-SSB antibody, anti-CENP-B antibody, anti-Ro-52 antibody, and anti-AMA-M2 antibody, especially anti-AMA-M2 antibody. When combined with ANA fluorescent karyotype and ANAs for analysis, if the fluorescent karyotype is nuclear particle type, the positive anti-Ro-52 antibody in ANAs is more valuable in distinguishing immunity from viral and drug-induced liver diseases.
