Objective To revise the Inventory of Alienation Toward Parents(IAP)and test its reliability and validity in a military population in order to provide a scientific tool for assessing the level and grade of parent-child alienation among military personnel.Methods Whole-cluster stratified random sampling was used to subject 8 641 service members from 8 Army units.Then all participants were surveyed with 18-item adolescent IAP,Beck Depression Inventory-Ⅱ,and Generalized Anxiety Disorder-7.SPSS 27.0 and AMOS 26.0 were used to perform item analysis,exploratory factor analysis(EFA),and confirmatory factor analysis(CFA)to assess reliability and validity.Subsequently,our revised 16-item version of IAP was employed to develop means,percentiles,cut-off scores,and category norms.Results ①Items 3 and 12 were deleted in item analysis.②EFA extracted the original communication and emotional distance factors;CFA indicated that the two-factor model had good fitness,with the mother-child alienation scale:χ2/df=4.248,comparative fit index(CFI)=0.962,Tucker-Lewis index(TLI)=0.929,root mean square error of approximation(RMSEA)=0.028,standardized root mean squared residual(SRMR)=0.023;while the father-child alienation scale:χ2/df=5.41,CFI=0.939,TLI=0.901,RMSEA=0.032,SRMR=0.044.③The internal consistency reliability of the total IAP was good(0.744～0.888).④The total IAP score and scores of the mother-child and father-child subscales were positively correlated with depression and anxiety(r=0.395～0.493,P<0.01).⑤ The average total IAP score for military personnel was 17.27±4.21,and the scores of mother-child alienation and father-child alienation were 8.64±2.26 and 8.62±2.43,respectively.With percentiles of P75 and P90 as the cut-off points,the total IAP score can be stratified into 3 levels,that is,normal(≤16),moderate(17～19),and severe(≥20).Then,additional category norms were developed based on demographic characteristics.Conclusion Our revised 16-item military version of IAP shows good reliability and validity.A preliminary and representative norm is developed primarily,and can be used to assess the level and grade of military parental alienation.

Objective To assess the retention and excretion fractions for uranium intake via wounds in the organs of adult reference computational phantom, and to improve the evaluation of health risks associated with radioactive isotopes intake via wounds. Methods A software for evaluation of the internal radiation dose was developed by combining the wound model in International Commission on Radiological Protection Report 156 and the systemic models in the International Commission on Radiological Protection Report 130 and the subsequent Occupational Intakes of Radionuclides series reports. This study was conducted to calculate the uranium retention fractions in adult reference individuals following ingestion through wounds of seven categories of uranium: weakly retained, moderately retained, strongly retained, very strongly retained, colloids, particles, and fragments. We assessed the retention fractions in the wound sites, bones, and liver, as well as the excretion fractions in urine and feces, and compared these results with authoritative results. Results The retention and excretion fractions of ²³⁸U and ²³⁵U in different forms of intake via wounds showed consistent variations. The retention fractions of weak and moderate uranium in wounds could be ignored after 1 000 d. The retention fractions of strong, avid, and colloid uranium were 10⁻⁴ to 10⁻⁵ after 10 000 d. A significant portion of the uranium present in the forms of particles and fragments exhibited long-term retention in wounds. The bone retention fractions were 1 to 2 orders of magnitude higher than the liver retention fractions. Following the intake of soluble and insoluble uranium, the retention fractions in these two organs decreased and increased, respectively, compared with those observed on the first day. The urinary excretion fractions were approximately 2 orders of magnitude higher than the fecal excretion fractions. Following the intake of soluble and particulate uranium, the excretion fractions decreased. At 1 000 d after the intake of uranium in the form of fragments, the urinary and fecal excretion fractions were 10⁻⁶ and 10⁻⁸, respectively. Conclusion The calculation results validated the accuracy of the established models, providing data support for the assessment of internal exposure doses in individuals following uranium wound contamination incidents.

Objective To investigate the effect of parent-child alienation on depression in surface ship officers and soldiers based on the theory of"diathesis-stress",and the mediating role of resilience between parent-child alienation and depression in them.Methods A cross-sectional study was conducted on 599 officers and soldiers from a surface ship unit.The participants were surveyed with inventory of alienation toward parents,connor-davidson resilience scale and patient health questionnaire-9 to obtain and analyze their demographic-military characteristics of their depression scores.The participants with depression scores ≥5 were recruited as the subjects,and Spearman correlation analysis was used to explore the correlation among parent-child alienation,resilience and depression.On the basis of hierarchical regression analysis,AMOS software was used to establish a structural equation modelling of intermediary effects.Results The depression score was 1(0,4)in the participants,and the depression scores of those with service length ≥11 years were comparatively higher than those with shorter length.Our results indicated that parent-child alienation was positive correlated with depression(r=0.451,P＜0.001),while resilience was negatively correlated with depression and parent-child alienation(r=-0.412,-0.407,P＜0.001).Regression analysis revealed that parent-child alienation had a direct positive predictive value for depression(β=0.574,P＜0.001),and resilience showed a negative predictive value for depression(β=-0.211,P＜0.01).Model analysis displayed that resilience had a significant mediating role in the effect of parent-child alienation on depression among these surface ship officers and soldiers,with an effect value of 0.088,and accounting for 15.86％of the total effect.Conclusion Parent-child alienation has a significant influence on depression among surface ship officers and soldiers,with resilience playing a partial mediating role.

Objective To investigate the current status of liver and gallbladder diseases and analyze the influencing factors of fatty liver based on the ultrasound examination results of officers and soldiers on a certain island.Methods The data of physical examination from 377 officers and soldiers on a certain island in 2021 were retrospectively analyzed.Age,gender,living habits,abdominal ultrasound results,and liver function test results were collected,and the incidence of liver and gallbladder diseases were investigated.Univariate and multivariate logistic regression analyses were used to screen the influencing factors of fatty liver disease.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of influencing factors for fatty liver disease.Results A total of 103 officers and soldiers were diagnosed with liver and gallbladder diseases.The top three were fatty liver(63.11%,65/103),gallbladder polyps(19.42%,20/103),and liver hemangioma(8.74%,9/103),accounting for 91.27%(94/103)of the subjects with liver and gallbladder diseases and 24.93%(94/377)of all the subjects undergoing physical examination.There were significant differences in the age,body mass index(BMI),the habit of mid night snacks,liver function indexes(alanine aminotransferase[ALT],aspartate aminotransferase[AST],total bilirubin[T-Bil],direct bilirubin[D-Bil],gamma-glutamyltransferase[γ-GT]),glucose(Glu),and triglyceride(TG)between the officers and soldiers with fatty liver(65 cases)and without fatty liver(312 cases)(all P<0.01).Multivariate logistic regression analysis showed that ALT,Glu,TG,BMI and the habit of midnight snacks were independent influencing factors of fatty liver(all P<0.05).The area under the ROC curve values of ALT,Glu,TG,BMI,the habit of midnight snacks and their combination in prediction of fatty liver were 0.776,0.621,0.764,0.828,0.637 and 0.866,respectively.Conclusion There is a high prevalence of fatty liver in officers and soldiers on a certain island(17.24%,65/377).ALT,Glu,TG,BMI and the habit of midnight snack can be used as a combined diagnostic model of fatty liver.The diet,exercise and training methods should be systematically and comprehensively managed to control related risk factors.Risk factor intervention and treatment should be carried out for high-risk population to effectively improve the physical and mental health of officers and soldiers on the island.

Objective: To investigate the risk factors for yersiniosis, so as to provide insights into prevention of yersiniosis. Methods: The patients with yersiniosis admitted to the clinics in the surveillance site of Chengbei Township of Jin'an District and Chengnan Township of Yu'an District in Lu'an City from 2013 to 2021 were included as the case group, and the healthy family members matched to cases were selected as the family control group, while normal residents with a 1︰2 match in the same village, gender, and age difference within 5 years were included in the community control group. Participants' demographics, hand-washing and eating habits, living environment hygiene, poultry and livestock feeding were collected using questionnaire surveys, and factors affecting yersiniosis were identified using a multivariable conditional logistic regression model. Results: There were 43 cases in the case group, with a median (interquartile range) age of 45 (34) years, 91 cases in the family control group, with a median (interquartile range) age of 36 (36) years and 86 cases in the community control group, with a median (interquartile range) age of 46 (34) years. Multivariable conditional logistic regression analysis showed that compared with the family control group, the habit of drinking unboiled water (OR=6.721, 95%CI: 1.765-25.588), and direct consumption of food stored in the refrigerator (OR=7.089, 95%CI: 1.873-26.829) were risk factors for yersiniosis in the case group; and compared with the community control group, not washing hands after contacting with poultry and livestock (OR=50.592, 95%CI: 2.758-927.997), habit of eating raw vegetables and fruits (OR=5.340, 95%CI: 1.022-27.887), direct consumption of food stored in the refrigerator (OR=19.973, 95%CI: 2.118-188.336), and unclean refrigerator (OR=12.692, 95%CI: 1.992-80.869) were risk factors for yersiniosis in the case group. Compared with the family and community control groups, not washing hands after contacting with poultry and livestock (OR=4.075, 95%CI: 1.427-11.637), habit of drinking unboiled water (OR=4.153, 95%CI: 1.331-12.957), habit of eating raw vegetables and fruits (OR=4.744, 95%CI: 1.609-13.993), and direct consumption of food stored in the refrigerator (OR=5.051, 95%CI: 1.773-14.395) were risk factors for yersiniosis in the control group. Conclusion Unhealthy habits such as eating raw vegetables and fruits, drinking unboiled water, direct consumption of food stored in the refrigerator, unclean refrigerator, and not washing hands after contacting poultry and livestock may increase the risk of yersiniosis.

Objective: To construct a model for clinical identification of spotted fever (SF) and severe fever with thrombocytopenia syndrome (SFTS), so as to provide insights into early identification of SF and SFTS. Methods: The clinical data of laboratory-confirmed SF and SFTS patients in secondary and tertiary hospitals in Lu'an City, Anhui Province from May 2017 to May 2021 were retrieved from Chinese Disease Prevention and Control Information System. Factors affecting SF were identified using a logistic regression model, and the model for early identification of SF and SFTS was created. The model fitting effect was evaluated using Hosmer-Lemeshow test, and the value of the model for identification of SF and SFTS was evaluated using the area under the receiver operating characteristic curve (AUC). Results: Data of 62 SF cases and 115 SFTS cases were included. Multivariable logistic regression analysis showed that rash (β=5.994), C-reactive protein (β=4.409), white blood cell (β=-3.176) and platelet (β=-3.234) were included in the model, which were scored 6, 4, -3 and -3, with a total score ranging from -5 to 10. Hosmer-Lemeshow test revealed a high model fitting effect (χ2=3.245, P=0.662). The AUC of the model was 0.992, and the sensitivity and specificity were 0.935 and 0.991 if the cutoff was 1. Conclusion A model for early identification of SF and SFTS that includes four variables of rash, C-reactive protein, white blood cell and platelet has been created, which has a high accuracy.

【Objective】 To investigate the diagnostic value of neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte (MLR), and lymphocyte (LYM) count in children with infectious mononucleosis (IM). 【Methods】 Clinical and laboratory data of 134 IM children hospitalized between September 2017 and March 2020 were collected. A total of 60 healthy children during the same period were selected as the control group. The subjects’ NLR, MLR, and LYM were calculated according to the results of peripheral blood. The values of NLR, MLR, and LYM in diagnosing and predicting IM were analyzed with ROC. 【Results】 The MLR and LYM values of IM children were significantly higher than those of the control group (P<0.01), while the NLR values of the two groups were not statistically significant (P>0.05). ROC results showed that the area under the ROC curve (AUC) of NLR was 0.397, AUC of MLR was 0.648, and LYM's AUC was 0.680. The ROC curve AUC of MLR+LYM was 0.878, the optimal threshold was 0.59, the sensitivity was 82.09%, and the specificity was 85.00%. 【Conclusion】 MLR and LYM are independent biomarkers for the prediction of IM in children.

Objective:To explore the pathogenic spectrum and epidemiological characteristics of respiratory viruses in children with acute lower respiratory tract infection in Changsha, and provide scientific basis for disease prevention and treatment.Methods:A total of 1 092 respiratory tract specimens of children were collected and 12 respiratory viruses were detected by real-time quantitative transcription polymerase chain reaction.Results:Among the samples from 1 092 cases, those from 437 cases (40%) were positive for respiratory syncytial virus (RSV), 337 cases (30.9%) were positive for parainfluenza virus-3 (PIV-3), 263 cases (24.1%) were positive for human bocavirus (HBOV) and 228 cases (20.8%) were positive for adenovirus (ADV). The detection rates of boys and girls were 82.26% and 83.42%. The infection rate of RSV was higher in the group ≤ 6 months of age, the infection rates of PIV-3 and HBOV ≤2 years old were higher, and the infection rate of ADV was higher in the group between 6 months to 5 years old. The detection rates of virus infection of spring, summer, autumn and winter were 90.48%, 83.50%, 62.26% and 82.80%, respectively, there were significant differences among them.Conclusions:The main viruses in children with acute lower respiratory tract infection in Changsha were RSV and PIV-3. Mixed infections were common. Children under 2 years of age were more likely to get acute lower respiratory infections. Viruses had seasonal trends and peaked in winter and spring.

Objective:To understand sexual needs and factors of risky sexual behaviors among elderly men at different ages in two communities of Qiandongnan Miao and Dong autonomous prefecture and provide basis for targeted HIV prevention and intervention.Methods:Two communities in the prefecture were selected as study sites. Questionnaire surveys were carried out among elderly men aged 50 and over who visited or consulted in the communities from June to December 2018, and they were tested for HIV and syphilis antibodies.Results:Among 400 elderly men, 209 (52.2%) were 50-64 years old, and 191(47.8%) were above 65 years old. They were mainly Miao people, accounting for 66.3% (265/400), and 235 (58.8%) had an education no more than 6 years. HIV awareness of the two age groups were only 25.8% (54/199) and 26.2% (50/191), respectively. Among those aged 50-64, 142 (68.0%) felt normal sexual desire, and 153 (73.6%) reported penile erections or erections in most cases whenever sex, and 52.9% (110) ejaculated most of the time. HIV prevalence was 1.0% (4/400). Compared with the over 65-year-old group, the proportion of having sex with spouse/stable partners (89.5%, 179/200), proportion of no condom use with their spouse/stable sexual partners during the most recent sex (93.8%, 168/179), proportion of having casual sex (11.0%, 23/209) and commercial sex (3.8%, 8/209) were all higher among 50-64 age group. In comparison to those aged over 65 years old, average monthly income>3 000, and use of sex helper, aged 50-64 ( OR=2.70, 95% CI: 1.22-5.95), average monthly income ≤1 000 yuan ( OR=2.79, 95% CI: 1.25-6.21), and no use of sex helper ( OR=3.78) (95% CI: 1.65-8.67) were related factors of HIV risky sexual behavior last time. Conclusion:Elderly men in the minority prefecture had low HIV awareness. Compared with those≥65 years old, the 50-64 age group had more active sexual behaviors and higher sexual needs. Those from 50-64 age group, with lower economic level and good sexual ability were more likely to have HIV risky sexual behaviors.
