[Objective] To explore the clinical features of IgG4-related urinary diseases so as to provide reference for the diagnosis and treatment of such diseases. [Methods] The clinical data of 4 cases of IgG4-related urinary system diseases diagnosed and treated in Xijing Hospital of Air Force Medical University during Aug.2019 and Dec.2023 were retrospectively collected.Here, we report on the diagnosis and treatment of these patients, analysing their symptoms, serology, imaging and pathology as well as their treatment and outcomes. [Results] The patients included 2 male and 2 female.The lesions were involved with the retroperitoneum and urinary system.Three patients had symptoms of lumbar pain.The imaging manifestations were complex, including retroperitoneal mass involving urinary system organs in 2 cases, tabdense shadow of the right kidney in 1 case, and simple cystic mass of kidney in 1 case.Serum IgG4 value was not detected before surgery.All patients underwent radical surgical treatment.Postoperative pathology showed fibrous tissue hyperplasia with a large number of plasma cells, lymphocytes, a few neutrophil infiltrates, and lymphoid follicles and obliterated vasculitis in some specimens.The number of IgG4⁺ plasma cells was more than 10 in all tissues under high power microscope.After surgery, 3 patients had symptoms improved, and serum IgG4 value was within the normal range; 1 patient (patem 3) had elevated IgG4 value during follow-up, received subsequent hormone therapy, and the serum IgG 4 level remained stable. [Conclusion] The symptoms of IgG4-related diseases involving the urinary system are non-specific, and the imaging findings are various, easily confused with other diseases.Early detection of serum IgG4 and biopsy pathology can help clinicians make correct diagnosis in the early stage.

Objective: To analyze the influence of stress and psychological resilience on the dietary behavior of middle school students so as to privide a basis for the development of policies and interventions aimed at improving middle school students dietary behavior. Methods: A total of 8 874 middle school students in Shanghai were surveyed using stratified cluster random sampling method from November 2019 to January 2020. The questionnaire included general information, dietary behavior, Perceived Stress Scale (PSS-10) and Connor-Davidson Resilience Scale (CD-RISC-10). Factor analysis was used to analyze the dietary behavior model. Logistic regression model was used to explore the correlation between stress, psychological resilience and dietary behavior in adolescents. Besides, a structural equation model was established to analyze the mediating effect of psychological resilience on stress and dietary behavior. Results: The total score of psychological resilience among middle school students was (27.99±9.83), and the total score of stress was (25.56±7.06). Factor analysis categorized dietary behavior into two types: the high energy dietary behavior and balanced dietary behavior. High energy dietary behavior exhibited statistically significant differences across genders and schooling stage ( χ 2=41.37, 204.03), while balanced dietary behavior showed statistically significant differences across schooling stage and socioeconomic status ( χ 2=130.23, 96.53) (all P <0.01). Logistic regression analysis showed that adolescents with moderate and high stress levels had an increased risks of high energy dietary behavior ( OR=1.25, 95%CI =1.12-1.39; OR=1.58, 95% CI = 1.39-1.79) and a reduced likelihood of reduced balanced dietary behavior ( OR=0.73, 95%CI =0.65-0.81; OR=0.53, 95%CI =0.47-0.60); adolescents with high levels of psychological resilience had a decreased risk of highenergy dietary behavior ( OR= 0.73 , 95%CI =0.65-0.83), and those with moderate and high resilience levels showed improved balanced dietary behavior ( OR= 1.45 , 95%CI =1.29-1.62; OR=2.50, 95%CI =2.21-2.84) (all P <0.01). The mediating effect of psychological resilience between stress and high energy dietary behavior or balanced dietary behavior accounted for 15.61% and 56.10% of the total effects, respectively. Conclusions Stress and psychological resilience are the influencing factors of dietary behavior in middle school students. Psychological resilience have a partial mediating effect between stress and high energy dietary behavior or balanced dietary behavior.

ObjectiveTo analyze the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Zhangjiakou City, Hebei Province from 2013 to 2022, so as to provide a basis for HFMD prevention, control, and evaluation of intervention effectiveness. MethodsHFMD data of Zhangjiakou City from 2013 to 2022 were collected. Descriptive statistics and the Joinpoint regression model were used to analyze the trend of the epidemic. ResultsThe incidence of HFMD in Zhangjiakou was predicted to decrease with APC=-14.86% in 2013‒2022. The top five regions with the highest incidence showed varying trends: Qiaodong District (APC=-26.21%), Qiaoxi District (APC=-18.29%), Xuanhua District (APC=-14.28%), Chicheng District (APC=-18.68%), and Zhuolu County (APC=51.43% in 2013‒2016, APC=-14.27% in 2016‒2022), indicating a downward trend. Three age groups showed an upward trend in incidence: the 0-year-old group (APC=-42.82% in 2013‒2016, APC=16.54% in 2016‒2022), the 7-year-old group (AAPC=9.60%), and the 9-year-old group (AAPC=12.76%). HFMD cases occurred throughout the year, peaking from June to August, with July being the most significant month. The male-to-female ratio was1.40∶1, with no statistical difference (χ²=5.932, P>0.05). A high incidence was in children under 5 years old, with those aged 1‒4 years being the main affected group. In terms of occupation, scattered children (6 245 cases, 57.65%) and preschool children (3 653 cases, 33.72%) were the most affected. A total of 504 laboratory-confirmed cases were reported, with a detection rate of 4.65% (504/10 832). The composition of confirmed cases included CoxA 16 (193 cases, 38.29%), EV71 (75 cases, 14.88%), and other enteroviruses (236 cases, 46.83%). ConclusionFrom 2013 to 2022, HFMD in Zhangjiakou City showed a downward trend with clear seasonal, regional, and occupational distributions. It is suggested that epidemic monitoring should be strengthened, etiological detection should be enhanced, and education efforts in key areas should be improved. High-incidence counties should analyze data and conduct risk assessments effectively.

Objective: To analyze the relationship between new surrogate marks of insulin resistance (IR) and bone mineral content (BMC) in adolescents, and predictive value of the new surrogate marks on low bone mass, so as to provide scientific basis for early identification and prevention of skeletal related diseases in adolescents. Methods: A total of 1 594 adolescents aged 12-18 years in Yinchuan City were selected by convenience sampling and stratified cluster random sampling from September 2017 to September 2020, and triglyceride and glucose index (TyG), triglyceride glucose-body mass index (TyG-BMI) and triglyceride/high density lipoprotein cholesterol (TG/HDL-C) were calculated as new simplified IR index. The correlation between different simplified IR indexes and BMC level was analyzed by partial correlation. Binary Logistic regression was used to analyze the relationship between IR index and low bone mass, and receiver operating characteristic (ROC) curve was constructed to analyze its evaluation effect on low bone mass. Results: After adjusting for confounding factors such as gender, age, smoking, drinking, family history of hypertension, systolic blood pressure (SBP) and diastolic blood pressure (DBP), the new surrogate marks of IR were positively correlated with BMC level (TyG: r =0.11, TyG-BMI: r =0.58, TG/HDL-C: r =0.21, P <0.01). After further adjustment of body mass index (BMI), fat mass (FM) and lean mass (LM), the relationship between IR indexes and BMC turned into negative correlation (TyG: r =-0.20, TyG-BMI: r =-0.18, TG/HDL-C: r=-0.14, P <0.01). After adjusting for confounding factors such as gender, age, smoking, drinking, family history of hypertension, SBP and DBP, Logistic regression results showed that the increase of TyG, TyG-BMI and TG/HDL-C levels reduced the possibility of low bone mass in adolescents (TyG: OR=0.63, 95%CI = 0.40-0.98, TyG-BMI: OR=0.94, 95%CI =0.93-0.96, TG/HDL-C: OR=0.31, 95%CI=0.17-0.58, P <0.01). After adjusting BMI, FM and LM, the above results were completely reversed. Girls with high TyG and TG/HDL-C levels were 4.95 and 4.38 times more likely to have low bone mass than those with low TyG and TG/HDL-C levels (TyG: OR=4.95, 95%CI =1.29- 18.95 , TG/HDL-C: OR=4.38, 95%CI=1.04-18.50, P <0.05). ROC curve showed that TyG-BMI had the best predictive value on low bone mass (AUC=0.80, 95% CI=0.77-0.83, P <0.01). Conclusion The new surrogate marks of IR in adolescents are negatively correlated with adolescent BMC, of which TyG-BMI is the best for assessing of low bone mass and can serving as a reliable indicator for early identification of low bone mass.

Objective:To explore and construct the nursing quality standards of spine surgery, provide a scientific basis for improving the nursing quality of spine surgery.Methods:Taking the "structure-process-outcome" three-dimensional quality model as the theoretical framework, through evidenced-based literature search and semi-structured interview, the items pool was formed, and finally the nursing quality standards were determined by two rounds of Delphi method of expert inquiry from May to July 2023.Results:The positive coefficients of the two rounds of inquiries to experts were 0.90 and 1.00, respectively. The authority coefficients were 0.946 and 0.951, respectively. The Kendall coefficients of the first, second and third level standards in the first round were 0.161, 0.095 and 0.108, respectively, and the Kendall coefficients of the first, second and third level standards in the second round were 0.162, 0.088 and 0.100, respectively, the differences were statistically significant (all P<0.05). The final nursing quality standards were finally constructed, including 3 first-level standards (structural quality, process quality and outcome quality), 20 second-level standards and 60 third-level standards.Conclusions:The nursing quality standards of spine surgery based on the three-dimensional quality model of "structure-process-outcome" have high reliability and science, which can provide target incentives for clinical nurses, provide a basis for the quality of specialized spine nursing, and promote the development of nursing specialization and the construction of nursing discipline.

Objective:To understand the prevalence of occasional hypertension in preschool children in three provinces in the middle and lower reaches of the Yangtze River in China, and analyze the relationship between their sleep status and occasional hypertension.Methods:From October to November 2017, a total of 24 842 preschool children from 109 kindergartens in 11 cities in Hubei, Anhui and Jiangsu provinces were selected by intentional sampling method. A self-made questionnaire was used to collect basic information about the subjects, and the sleep status data was collected by the Children′s Sleep Habits Questionnaire. Physical examinations were performed on the subjects, and height, weight and blood pressure were measured on-site. The difference in occasional hypertension detection rate among preschool children with different characteristics was compared, and the correlation between sleep status and occasional hypertension detection rate was analyzed by the multivariate logistic regression model.Results:The age of the subjects was (4.4±1.0) years, including 12 729 boys (51.2%). The prevalence of occasional hypertension was 31.8% (7 907/24 842). The prevalence of occasional hypertension among preschool children in three provinces of the middle and lower reaches of the Yangtze River was 31.8%. There were statistically significant differences in the detection rate of occasional hypertension among preschool children of different genders, age groups, family residence, family economic status and parents′ education level (all P values<0.05). The detection rate of occasional hypertension in children with less than 10 hours of sleep was higher than those with sufficient sleep, and the difference was statistically significant ( P<0.05). The results of multivariate logistic regression analysis showed that after adjusting for factors such as gender, age, family residence, family economic status, parental education level, parental smoking history, and physical constitution, the ORs (95% CI) for less than 10 hours of sleep, turning on the lights while sleeping, and poor sleep quality were 1.09 (1.03-1.15), 1.17 (1.07-1.28) and 1.04 (0.91-1.18), respectively, compared with the corresponding reference group. Conclusion:The detection rate of occasional hypertension is high in preschool children in the middle and lower reaches of the Yangtze River and there is a positive correlation between insufficient sleep and turning on the light when sleeping and occasional hypertension in preschool children.
