Objective:To investigate the risk factors of wet ear status and its impact on the efficacy of endoscopic type Ⅰ tympanoplasty. Methods:A retrospective analysis was conducted at the Department of Otolaryngology Head and Neck Surgery, the First Affiliated Hospital of Chinese People's Liberation Army（PLA）Air Force Medical University, on 160 ears that underwent endoscopic type Ⅰ tympanoplasty; these were assigned to a dry-ear group （n= 118） and a wet-ear group （n= 42）.Univariate analysis and binary logistic regression were used to identify risk factors for wet ear status. Postoperative outcomes, including tympanic meoombrane healing rate and hearing improvement across frequencies, were compared between groups. Results:①Significant intergroup differences were observed in age, residual tympanic membrane status, external auditory canal condition, mastoid pneumatization（MC0）, and middle ear ventilation dysfunction（P<0.05）; ②The degree of mastoid pneumatization being MC0 is an independent risk factor for wet ear（P<0.05）; ③No significant difference in tympanic membrane healing rates was found（P>0.05）; ④The wet ear group showed significantly higher pre-and postoperative air-conduction（AC） and bone-conduction（BC） thresholds at 2 kHz and 4 kHz compared to the dry ear group（P<0.05）, though the postoperative air-bone gap（ABG） improvement was comparable. Conclusion:Poor mastoid pneumatization is a risk factor for wet ears. The wet ear state has no effect on tympanic membrane healing and air-bone conduction gap, but patients in the wet ear group may have more severe inner ear or auditory nerve pathway damage.

Objective The long-term epidemiological and etiological characteristics of hand, foot and mouth disease (HFMD) in Huai’an, Jiangsu were analyzed to provide scientific evidence for the prevention of HFMD. Methods The data of HFMD reports, etiological diagnosis and in Huai’an from 2009 to 2022 were described and analyzed. Results A total of 78 535 cases were reported from 2009 to 2022 , with 14-year average annual incidence rate of 114.71/100 000. Before 2020, the incidence rate of HFMD in Huai’an showed the epidemic intensity increased every other year on the whole, and the average annual incidence rate during the COVID-19 pandemic (2020-2022) (55.69/100 000) was significantly lower than that in previous years (2009-2019) (129.95/100 000). The joinpoint regression analysis showed that the best fitting model from 2009 to 2022 had no joinpoints, APC=AAPC=-1.24%. The overall trend showed a monotonously decreasing trend, but the trend was not statistically significant. The male-to-female distribution ratio was 1.53:1, and the age distribution was mainly under 5 years old, especially in scattered children. The epidemic season was from April to July. The results of etiological surveillance showed that the co-epidemic of Coxsackievirus A16 (CV-A16) and Enterovirus A71 (EV-A71) during the early stages had changed to the co-epidemic of CV-A16 and CV-A6 in the current period. Conclusion The burden of HFMD in Huai’an was large, and the epidemic intensity increased every other year was affected by the COVID-19 pandemic. The epidemiological features after the COVID-19 pandemic should be further monitored.

Objective:To analyze the association between visceral fat area (VFA) and fatty liver based on quantitative CT (QCT) in people receiving health examination with normal body mass index (BMI).Methods:A cross-sectional study. A total of 1 305 physical examiners who underwent chest CT and QCT examination in the Department of Health Management of Henan Provincial People′s Hospital from January to December 2021 were retrospectively selected as subjects. The physical components at the central level of the lumbar two cone were measured with QCT, including subcutaneous fat area (SFA), VFA and liver fat content (LFC). And the metabolic indexes, such as blood lipids and blood glucose, were collected. The t-test and χ2 test were used to analyze the correlation between the detection rate of fatty live and LFCr and age and gender. According to level of VFA (<100 cm 2, 100-150 cm 2 and≥150 cm 2), the subjects were divided into three groups, and one-way ANOVA and χ2 test were used in comparison between groups. Multiple linear regression was used to analyze the correlation between VFA and metabolic indexes and LFC. Results:Of the 1 305 subjects, there were 634 males and 671 females. The detection rate of fatty liver in normal BMI population was 65.67%, and it was 72.71% and 59.02% respectively in men and women ( χ2=27.12, P<0.001), and the detection rate of fatty liver and LFC increased with age (both P<0.05). With the increase of VFA, the age, BMI, SFA, LFC, total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), alanine aminotransferase (ALT), blood uric acid and prevalence of fatty liver increased (all P<0.05), and the low-density lipoprotein cholesterol (HDL-C) decreased ( P<0.001). Multiple linear regression analysis showed that after adjustment for age factors, regardless of male or female, LFC was independently positively related with VFA, BMI, and ALT (male β=0.206, 0.145, 0.174, female β=0.194, 0.150, 0.184; all P<0.05). FBG was positively correlated with male independently ( β=0.134; P<0.001). The indicators related to female independently were TC, TG, and blood uric acid ( β=-0.121, 0.145, 0.141, all P<0.05) Conclusion:In the population receiving health examination with normal BMI, the VFA measured by QCT technique is closely related to fatty liver.

Objective To explore the value of machine learning(ML)models based on non-contrast CT(NCCT)radiomics features for predicting the severity of acute phase traumatic brain injury(TBI).Methods Totally 600 TBI patients were retrospectively collected as observation group,other 65 TBI patients were taken as external validation set,while 50 TBI patients were prospectively enrolled as prospective validation set.Patients in observation group were divided into high-risk subgroup(n=240)and low-risk subgroup(n=360)according to Glasgow outcome scale(GOS)at discharge.The severity of acute phase TBI in observation group was assessed by doctor A and B with the same criteria,then an artificial model was established based on clinical and NCCT data at the time of first diagnosis using logistic regression(LR)method for predicting the severity of acute phase TBI.Patients in observation group were divided into training set(n=420,including 168 in high-risk subgroup and 252 in low-risk subgroup)and test set(n=180,including 72 in high-risk subgroup and 108 in low-risk subgroup)at the ratio of 7∶3.Based on NCCT of training set,radiomics features were extracted and selected,and LR,support vector machine(SVM),random forest(RF)and K-nearest neighbor(KNN)were used to establish 4 ML models.The efficacies of the above models were validated in test set,external validation set(including 34 cases of high-risk and 31 cases of low-risk TBI)and prospective validation set(including 21 cases of high-risk and 29 cases of low-risk TBI),respectively.Results The area under the curve(AUC)of doctor A and B for evaluating the severity of acute phase TBI in observation group was 0.606 and 0.771,respectively,of artificial model was 0.824.Based on NCCT in training set,6 optimal radiomics features were selected to construct LR,SVM,RF and KNN ML models,with AUC of 0.983,0.971,0.970 and 0.984 in test set,respectively,while the AUC of artificial model was 0.708.The AUC of LR,SVM,RF,KNN ML models and artificial model in external validation set was 0.879,0.881,0.984,0.863 and 0.733,while in prospective validation set was 0.984,0.873,0.982,0.897 and 0.704,respectively.Conclusion ML models based on CT radiomics could effectively predict the severity of acute phase TBI.

Objective To explore the content and the psychometric properties of assessment tools used for evaluating functioning and adaptive behavior in school-age children with intellectual and developmental disabilities within educational settings. Methods The most used assessment tools included Vineland Adaptive Behavior Scales(VABS),Supports Intensity Scale for Children(SIS-C),Strengths and Difficulties Questionnaire(SDQ)and Repetitive Behavior Scale-Revised(RBS-R),for assessing functioning and adaptive behavior children with intellectual and developmental disabili-ties.Employing the framework and methods of the International Classification of Functioning,Disability,and Health(ICF),this research encoded and categorized the assessment dimensions and items of the four tools,and explored their psychometric properties. Results VABS's assessment content was solely focused on activities and participation,including speaking(d330),con-versation(d350),toileting(d530),eating(d550),drinking(d560),basic interpersonal interactions(d710),com-plex interpersonal interactions(d720),changing and maintaining body positions(d410-d429),carrying,moving and handing objects(d430-d449),and walking and moving(d450-d469).SIS-C assessed activities and participa-tion,and environmental factors,including washing oneself(d510),caring for body parts(d520),community life(d910),using transportation(d470),school education(d820),basic learning(d130-d159),looking after one's health(d570),basic interpersonal interactions(d710),and products and technology for education(e130).SDQ fo-cused on body functions,and activities and participation,including emotional functions(b152),global psychoso-cial functions(b122),attention functions(b140),and basic interpersonal interactions(d710).RBS-R focused on body functions,and activities and participation,including involuntary movement reaction functions(b755),invol-untary movement functions(b765),looking after one's health(d570),energy and drive functions(b130),under-taking a single task(d210),carrying out daily routine(d230),attention functions(b140),and handling stress and other psychological demands(d240).VABS was characterized by good specificity and excellent sensitivity.SIS-C demonstrated very good internal consistency,reliability and validity.SDQ was good in internal consistency,with excellent credibility and validity.RBS-R showed good internal consistency,reliability and validity. Conclusion SDQ and RBS-R cover both body functions,and activities and participation,SIS-C covers activity and par-ticipation,and environmental factors,while VABS solely assesses activities and participation.In terms of body functions,the assessment items primarily focus on mental functions(b130-b189)and movement functions(b750-b799).For activities and participation,the tools assess content across eight domains of functioning.Regarding en-vironmental factors,the assessment content mainly includes products and technology for education(e130),as well as design,construction and building products and technology of buildings for public use(e150).VABS,SIS-C,SDQ,and RBS-R are all norm-referenced measures,with moderate to excellent internal consistency,and good to excellent reliability and validity.

Objective:This study aims to explore the prevalence of hepatitis E virus (HEV) infection in patients and the screening value of serological indicators for HEV infection patients.Methods:Retrospective analysis was conducted on 97 440 cases of anti-HEV IgM and IgG simultaneously tested in two Beijing hospitals from January 1, 2018 to August 31, 2023. Among them, there were 61 005 males and 36 435 females, with an average age of 51.65±13.05 years old. According to the positivity of anti HEV specific antibodies, they were divided into anti-HEV IgM positive group (3 588 cases), anti-HEV IgG positive group (18 083 cases), and anti-HEV antibody negative group (78 892 cases). Results of HEV RNA, liver function, AFP, PIVKA-Ⅱ and PT were collected, and their basic clinical information were recorded. The prevalence of HEV infection in patients, as well as the relationship between the positivity of anti-HEV specific antibodies and the patient′s age group, HEV RNA, and clinical characteristics were analyzed.Results:Among 97 440 patients who tested anti-HEV IgM and IgG simultaneously, the positivity rate of anti-HEV IgM was 3.68% (3 588/97 440), and was 18.56% for anti-HEV IgG (18 083/97 440). The overall positivity rates of anti-HEV IgM in two Beijing hospitals from 2018 to 2023 were 2.51%, 2.53%, 3.02%, 4.59%, 5.72%, and 4.26% ( χ2=1 401.73, P<0.001), while the positivity rates of anti-HEV IgG were 12.56%, 12.32%, 12.85%, 22.65%, 27.42%, and 26.66% ( χ2=1 058.29, P<0.001). These rates showed a gradual increase until 2023 when a decline was observed. The positivity rates of anti-HEV IgM (2.28%, 3.60%, 4.47%) ( χ2=89.62, P<0.001) and IgG (4.71%, 17.86%, 25.94%) ( χ2=2 017.32, P<0.001) increased with age in patients who aged 1-30, >30-60, and over 60 years old. The age and ALB values of patients in the anti-HEV IgM positive group were lower than the IgG-positive group, while the proportion of males, TBIL, ALT, AFP and PT values were higher than the IgG-positive group, and the differences were statistically significance ( P<0.05). Furthermore, patients in both the anti-HEV IgM and IgG positive groups had higher age, male proportion, TBIL, ALT, AFP, PIVKA-Ⅱ, and PT values than the anti-HEV negative group. Additionally, both groups had lower ALB values than the anti-HEV negative group, all of which were statistically significant ( P<0.05). 2 162 HEV infected patients were grouped based on HEV RNA positivity. The proportion of anti-HEV IgM single positive, IgG single positive, IgM+IgG double positive, and antibody negative patients in the HEV RNA positive group were 5.42% (18/332), 3.62% (12/332), 90.36% (300/332), and 0.60% (2/332), respectively. Among them, the proportion of anti-HEV IgM+IgG double positive patients in the HEV RNA positive group was higher than that in the HEV RNA negative group ( χ2=302.87, P<0.001), while the proportion of anti-HEV IgG single positive ( χ2=174.36, P<0.001) and anti-HEV antibody negative patients ( χ2=59.28, P<0.001) were lower than that in the HEV RNA negative group, both of which were statistically significant ( P<0.001). In addition, the positive rates of HEV RNA in anti-HEV IgM positive, IgG positive, and antibody negative patients were 29.23% (318/1 088), 17.59% (312/1 774), and 0.65% (2/306), respectively. Conclusion:The HEV infection rate among patients declined in 2023. HEV infection is age-related, with older individuals being more susceptible. Abnormal liver function and jaundice were commonly observed during HEV infection. It is crucial to note that the absence of anti-HEV specific antibodies cannot rule out HEV infection; therefore, additional testing for HEV RNA and/or HEV Ag is necessary for accurate diagnosis.

Non-alcoholic fatty liver disease(NAFLD) has become the main cause of chronic liver disease in children worldwide, and the incidence of NAFLD shows an increasing trend year by year. The risk factors leading to the onset of NAFLD in children are diversified and different from those in adults. At present, most medical institutions still pay little attention to NAFLD in children. This paper summarizes the risk factors and mechanisms for NAFLD in children, including gene polymorphism, maternal and fetal conditions, diet and living habits, environmental exposure, metabolic syndrome, endocrine-related mechanisms and intestinal microecology, in order to provide reference for the prevention and management of childhood NAFLD.

Epilepsy is a kind of brain dysfunction syndrome characterized by paroxysmal,transient,repetitive and rigid characteristics caused by abnormal discharge of highly synchronized neurons in the brain.Epilepsy is often accompanied by cognitive dysfunction.At present,anti-seizure medications are the most important methods of clinical treatment.Most of the traditional anti-seizure medications can cause cognitive dysfunction,and the influence of new anti-seizure medications on cognitive function is not completely clear.This paper reviews the influence of new anti-seizure medications on cognitive function and the possible related mechanisms of action based on relevant literature at home and abroad.It is expected that clinicians should pay attention to cognitive function in the process of diagnosis and treatment of epilepsy,and help clinicians realize the influence of anti-seizure medications on cognitive function,and rationally choose anti-seizure medications for patients.

OBJECTIVE To establish a clinical pharmaceutical pathway of anti-infective therapy for high-risk populations of antibiotic-associated encephalopathy （AAE）， and analyze its application effects. METHODS Clinical pharmacists developed the “AAE High-Risk Population Screening Form” and “Antibiotic AAE Risk Comparison Form” based on literature and expert opinions， and established the “Clinical Pharmaceutical Pathway of Anti-infective Treatment for AAE High-Risk Population” in our hospital. A prospective， non-randomized controlled study was conducted from May 2023 to April 2024， including 50 cases in the observation group and 50 cases in the control group among patients with pulmonary infections admitted to the Dept. of Internal Medicine in our hospital. The observation group was involved in the development of an anti-infective treatment following the clinical pharmaceutical pathway by clinical pharmacists， while the control group received routine anti-infective treatment by clinical physicians. The occurrence of AAE， the rational antibiotic drug use， and the effectiveness of initial anti-infective treatment in the two groups were observed， and the intervention measures and outcomes of AAE cases were summarized. RESULTS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population was preliminarily established in our hospital. The analysis of the application effects showed that there was 1 case of AAE in the observation group and 8 cases in the control group， with a significantly lower incidence of AAE in the observation group than in the control group； the rational antibiotic drug use and the effectiveness of initial anti-infective treatment in the observation group were both significantly superior to those in the control group （P＜0.05）. Drug withdrawal and dressing change were the preferred effective intervention measures for AAE， and encephalopathy treatment drugs could be used as auxiliary measures for symptom relief. Timely and effective intervention was conducive to rapid symptom relief， with a total improvement rate of AAE of 88.89%. CONCLUSIONS The anti-infective treatment clinical pharmaceutical pathway for AAE high-risk population can effectively prevent the occurrence of AAE as well as contribute to promoting rational drug use and the effectiveness of initial anti-infection plans and strengthening treatment outcomes.
