Objective:To explore the value of multimodal ultrasound parameters combined with peripheral blood lymphocyte-monocyte ratio (LMR) in predicting recurrence and metastasis after radical breast cancer surgery.Methods:A total of 139 patients with breast cancer admitted to Northwest Women’s and Children’s Hospital from Jan. 2021 to Jan. 2022 were studied. The patients underwent postoperative multimodal ultrasonography and peripheral blood lymphocyte and monocyte examination. Patients were followed up for 2 years after surgery to evaluate postoperative recurrence and metastasis, and analyze the value of multimodal ultrasound parameters combined with LMR in predicting recurrence and metastasis of patients.Results:Among 139 patients, 32 recurrences and metastases occurred during 2-year follow-up; The peak systolic velocity (PSV), resistance index (RI), maximum lesion diameter, elasticity score, area under the curve (AUC) and peak intensity (PI) in patients with recurrent metastasis were higher than those without recurrent metastasis ( t=7.37, 4.75, 4.75, 5.46, 4.24, 5.22, P<0.05), and the LNR in patients with recurrent metastasis was lower. Pearson correlation analysis showed that PSV, RI, maximum lesion diameter, elasticity score, AUC, PI were negatively correlated with LMR ( r=-0.418, -0.502, -0.633, -0.526, -0.448, -0.482). P<0.05) ; The ROC curve showed that the AUC of PSV, RI, maximum lesion diameter, elasticity score, AUC, PI and LMR for predicting recurrence and metastasis were 0.852, 0.784, 0.791, 0.789, 0.615, 0.725 and 0.728, respectively, and the combined AUC value of each index was 0.992. Conclusions:The use of multimodal ultrasound parameters combined with LMR can improve the prediction value of recurrence and metastasis after radical breast cancer surgery.

To analyze the current quality of treatment for hospitalized cancer patients in Beijing, identify major issues in treatment practices, and propose improvements.

Objective To investigate the impact of the change in anti-hepatitis B virus (HBV) therapy indication on treatment rate and the features of the population requiring treatment. Methods The treatment-naïve patients with chronic hepatitis B (CHB) in the China Registry of Hepatitis B (CR-HepB) database were selected as subjects, and related demographic, virological, hematological, and biochemical data were collected. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results A total of 3640 treatment-naïve CHB patients were included in this study, among whom 64.4% were male, 68.7% had an age of 30-59 years, and 46.8% had an indeterminate clinical stage. According to the 2015 and 2019 editions of Guidelines for the prevention and treatment of chronic hepatitis B and the 2022 edition of expert consensus, the number of patients who had the indication for antiviral therapy was 625(17.2%), 1333(36.6%), and 2890(79.4%), respectively. The number of patients requiring treatment was increased by 1557 according to the 2022 edition of expert consensus, among whom 1424(91.5%) met the treatment threshold of alanine aminotransferase (ALT) > 30 U/L for male patients or ALT > 19 U/L for female patients. The additional patients requiring treatment according to the 2022 edition of expert consensus had significantly higher levels of ALT and HBV DNA and significantly lower scores of APRI and FIB-4 than the additional patients requiring treatment according to the 2019 edition of Guidelines (all P < 0.05). Conclusion The expansion of antiviral therapy indications for CHB may significantly increase the proportion of CHB patients receiving antiviral treatment and help mild CHB patients at the risk of disease progression to receive timely treatment and achieve the improvement in long-term prognosis.

Objective:To investigate the current situation of psychological distress in patients after pulmonary nodule surgery and to explore the effect path of perceived stress and nurses' caring ability on psychological distress.Method:From October 2019 to May 2021, a total of 415 patients with pulmonary nodules after surgery in the First Medical Center of Chinese PLA General Hospital were selected as the investigation objects by the convenient sampling method. The Psychological Distress Thermometer, Caring Ability Scale, Perceived Stress Scale and General Information Questionnaire were used for investigation and analysis. Structural equation model was used to analyze the effect of perceived stress on psychological distress. A total of 415 paper questionnaires were distributed and 411 valid questionnaires were recovered, with an effective recovery rate of 99.04%.Results:The psychological distress score of 411 patients with pulmonary nodules after operation was (4.82±1.42) , and 179 patients (43.55%) had a score greater than or equal to 4. There were statistically significant differences in the psychological distress scores of inpatients with different marriage, pulmonary nodule types, fear of cancer, emotional self-regulation ability, e-health literacy and disease awareness after pulmonary nodule surgery ( P<0.01) . Psychological distress was negatively correlated with nurses' caring ability ( r=-0.626, P<0.01) , and positively correlated with perceived stress ( r=0.596, P<0.01) . The mediating effect value of nurse' caring ability between sense of loss of control and psychological pain was 0.132, accounting for 32.84% (0.132/0.402) of the total effect. Conclusions:The psychological pain of patients after pulmonary nodule surgery is closely related to perceived pressure and nurses' caring ability. The nurses' caring ability has a partial mediating effect between the sense of loss of control and psychological pain. Improving nurses' caring ability can reduce the psychological distress of patients after pulmonary nodule surgery.

Objective:To investigate the relationships between hyperuricemia and the incidence risk for cardiometabolic abnormity in children.Methods:Data were obtained from School-based Cardiovascular and Bone Health Promotion Program. In 2017, a total of 15 391 children aged 6-16 years in Beijing were selected through stratified cluster sampling at baseline survey. Follow-up investigation was conducted in 2019. Logistic regression model was used to analyze the relationships of uric acid quartiles and change in uric acid levels with incidence risks for cardiometabolic abnormity (hypertension, hyperglycemia and dyslipidemia).Results:A total of 8 807 children (4 376 boys, 4 431 girls) were included in the analysis, the average age of the children was (11.1±3.3) years at baseline survey. The adjusted odds ratios ( ORs) and 95% confidence intervals ( CIs) of incidence risk for hypertension in the third and fourth quartiles of the UA were 1.39 (1.11-1.75) and 1.56 (1.19-1.81), respectively. The ORs and 95% CIs of risk for high LDL-C in the second, third and fourth quartiles were 1.88 (1.16-3.05),1.98 (1.23-3.17) and 2.25 (1.42-3.57). The uric acid level increased by one standard deviation, the risk increased by 17% for hypertension and 27% for high LDL-C. The uric acid level increased by 10 μmol/L, the risk increased by 2.1% for hypertension and 2.9% for high LDL-C. The gender-stratified analysis showed that the similar results. The ORs and 95% CIs were 1.32 (1.09-1.60) and 1.50 (1.05-2.16) for hypertension, 1.90 (1.38-2.60) and 2.96 (1.58-5.52) for high TC, 1.78 (1.26-2.51) and 2.84 (1.60-5.03) for high LDL-C in the groups of newly diagnosed hyperuricemia and persistent hyperuricemia. Conclusions:Higher uric acid level was associated with increased incidence risks for hypertension, abnormal TC and LDL-C. Maintaining optimal uric acid level by children might contribute to the early prevention of cardiovascular diseases.

Objective:To analyze the influence of obesity status on the development of cardiometabolic disorders in school-age children.Methods:Information about children's body weight, body height and cardiovascular risk factors were collected in baseline survey in 2017 and follow-up survey in 2019. The school-age children were divided into four groups based on their baseline and follow-up obesity status, i.e. sustained non-obesity group, restored obesity group, newly classified obesity group, and persistent obesity group. Analysis of covariance was used to compare the difference of change in levels of cardiometabolic factors among the four groups. The multivariate logistic regression model was used to analyze the relationship between obesity status and the incidence risk of cardiometabolic disorders.Results:The present study included 11 379 school-age children (boys accounting for 49.6%). During the 2 years, the incidence of obesity was 3.2% (95% CI: 2.9%-3.5%) with the restoration ratio of obesity of 4.4% (95% CI: 4.0%-4.8%). Compared with the sustained non-obesity group, increases in SBP, DBP, TG, LDL-C and non-HDL-C were much higher in newly classified obesity group and persistent obesity group, but lower in restored obesity groups except for DBP (all P<0.05). In addition, the incidence risk of hypertension, high glucose, dyslipidemia and cardiometabolic disorders (≥2 risks) were much higher in newly classified and persistent obese children than in sustained non-obese children. No difference was found in incidence risks of most cardiovascular disorders between restored obese children and sustained non-obese children, except for hypertension and cardiometabolic risks. Conclusion:Both newly classified obesity and persistent obesity increased the incidence risks for multi cardiovascular disorders, while these risks could be reduced when non-obese status restore.

Objective:To investigate the incidence and risk factors of pediatric fracture in school-age children and adolescents in Beijing.Methods:A total of 12 056 students with complete fracture data of 2017 baseline survey and 2019 follow-up survey of School-based Cardiovascular and Bone Health (SCVBH) Promotion Program in Beijing were selected as study subjects. Logistic regression model was used to analyze associations of fracture incidence with age, BMI, fracture history and lifestyle.Results:The 2-year accumulative incidence rate of pediatric fracture was 3.1% (95% CI: 2.8%-3.4%) in school-age children and adolescents in Beijing, which was much higher in boys (4.1%) than in girls (2.1%) and increased with age in boys but decreased with age in girls. Fractures mainly occurred at upper-limb (69.0%), no gender and age specific significant in fracture sites were observed. Fracture history was the risk factor for fracture incidence in both boys and girls (boys: RR=1.81, 95% CI: 1.18-2.64; girls: RR=3.11, 95% CI: 1.74-5.13). In addition, higher duration and frequency of moderate to vigorous physical activities (≥120 min/day) and frequent consumption of sugar sweetened beverage (≥1 time/week) were also found to increase fracture risk in boys. Conclusion:The incidence of pediatric fracture was associated with gender, age, fracture history and lifestyle habits in school-age children and adolescents in Beijing. Targeted strategies are needed to prevent childhood fracture.

Objective:To investigate the association between vitamin D nutritional status and the body muscle mass in children.Methods:Data were obtained from School-based Cardiovascular and Bone Health Promotion Program. In 2017, a total of 15 391 children aged 6-16 years in Beijing were selected through stratified cluster sampling in baseline survey. A follow-up investigation was conducted in 2019. The questionnaire survey and the detection of serum 25-hydroxyvitamin D [25(OH)D] level were conducted. The bioelectrical impedance analysis (BIA) apparatus was used to measure body muscle mass, and muscle mass index (MMI) was calculated. Multivariable linear models were used to analyze the association of vitamin D nutritional status with the baseline and follow-up MMI measures.Results:A total of 10 890 children aged (11.5±3.3) years(boys accounting for 49.6%) were included in the analysis. The average 25(OH)D level was (35.4±12.0) nmol/L, with an adequacy ratio of 11.1%. After multivariate linear regression adjustment for age, sex, body fat mass, smoking status, alcohol use status, dairy supplement, calcium supplement, physical activity, and pubertal development, no statistically significant association between vitamin D nutritional status and baseline MMI level was observed ( P>0.05). For the follow-up MMI, the Z-score increased by 0.008 ( P=0.058) for per 10 nmol/L increase in 25(OH)D, which were 0.002 ( P=0.815) and 0.037 ( P=0.031) higher in children with insufficient and adequate vitamin D than those with vitamin D deficiency, respectively ( P for trend =0.089). Subgroup analysis showed that in the normal BMI group, for per 10 nmol/L increase in 25 (OH) D, the MMI at baseline survey and MMI Z-score at follow-up of children with adequate vitamin D and increased by 0.019 and 0.014, respectively (both P<0.05). Conclusions:Vitamin D nutritional status was related to muscle mass in children, and children with adequate vitamin D tended to obtain higher MMI. Children and adolescents are encouraged to maintain sufficient vitamin D levels, strengthen nutrition and exercise to promote body health.

Objective:To investigate the relationships between vitamin D nutritional status and the calcaneal bone mineral density (BMD) in children.Methods:Data were obtained from School-based Cardiovascular and Bone Health Promotion Program. In 2017, a total of 15 391 children aged 6-16 years in Beijing selected through stratified cluster sampling were included in the baseline survey. A follow-up investigation was conducted in 2019. The questionnaire survey, detection of serum 25-hydroxyvitamin D [25(OH)D] level and ultrasound measurement of calcaneal BMD were conducted. Multivariable linear and logistic regression models were used to analyze the relationships between baseline vitamin D nutritional status and the follow-up calcaneal BMD.Results:A total of 10 914 children aged (11.5±3.3) years (boys accounting for 49.6%) were included in the analysis. The average 25(OH)D level was (35.4±12.0) nmol/L, and the deficiency rate was 36.1%. After the adjustment for age, gender, body mass index, smoking status, alcohol use status, dairy products intake, vitamin D supplement, calcium supplement, physical activity, pubertal development, and baseline calcaneal BMD Z-score, for per 10 nmol/L increase in 25(OH)D, the follow-up calcaneal BMD Z-score increased by 0.01( P=0.041), and the OR(95% CI) of decreased calcaneal BMD Z-score after 2 years was 0.96 (0.93-1.00)( P=0.030). Compared with vitamin D adequacy, the follow-up calcaneal BMD Z-score of children with vitamin D insufficiency and deficiency decreased by 0.03( P=0.307) and 0.06 ( P=0.046), and the risk of decreased calcaneal BMD Z-score after 2 years increased by 15%( P=0.037) and 21%( P=0.006), respectively ( P for trend<0.05). Conclusions:Vitamin D nutritional status was closely related to calcaneal BMD, and children with adequate vitamin D nutritional status tended to obtain higher BMD. Children and adolescents are encouraged to maintain sufficient vitamin D levels, strengthen nutrition and exercise to promote bone health.
