Objective:
To analysis the epidemiological characteristics of overweight and obesity among middle school students in Taizhou from 2013 to 2020, to provide support for prevention and control efforts.
Methods:
Through stratified sampling, one primary school, one junior middle school and one senior high school were randomly selected from nine counties (cities and districts) in Taizhou, and continuous monitoring was conducted in all participants Height, weight and other variables were assessed and body mass index was calculated. The epidemic characteristics were analyzed according to the detection rate, fixed base ratio, sequential growth ratio and average growth rate.
Results:
From 2013 to 2020, the overall overweight rate among primary and middle school students in Taizhou was 14.5%(36 592/252 583), and the obesity rate was 11.2%(28 256/252 583). The rates of overweight and obesity increased, with average annual growth rates of 1.9% and 5.5%, respectively; thus, the rate of obesity increased more rapidly. The obesity rate was higher among boys (13.2%) than girls (9.0%)( χ 2=1 119.57, P <0.01), and the average annual growth rate was higher among girls than boys (6.1%, 5.2%, respectively). The rate of overweight among boys (17.6%) was higher than that among girls (10.9%)( χ 2=2 307.35, P <0.01). The average annual growth rate of overweight in girls was 2.3% and 1.7%, respectively. The obesity rate among primary school students (17.5%) was higher than that among middle school (9.7%) and high school (4.9%) students( χ 2=7 291.33, P <0.01). The average annual growth rate in students in middle school was fastest, followed by those in high and primary schools (6.5%, 3.9% and 2.6%, respectively). The rate of overweight in primary school students ( 15.8 %) was higher than that in middle school students (15.3%), and both were higher than that in high school students(12.2%)( χ 2=521.06, P <0.01). The average annual growth rate was also fastest in students in middle school, followed by high and primary schools (2.4%, 2.2% and 0.6%, respectively).
Conclusion
The detection rate of overweight and obesity among primary and middle school students in Taizhou is high and increasing rapidly, indicating high pressure on prevention and control. Boys and primary school students are the key target groups for prevention and control. Comprehensive prevention and control strategies should be adopted specifically.

Objective:To investigate the clinical features of pediatric patients with intracranial primary non-germinomatous germ cell tumors (NGGCT) and evaluate the treatment outcomes and prognostic factors of NGGCT.Methods:Clinical data of 40 children with NGGCT who were treated with radiotherapy (RT) at our department between November 2008 and June 2019 were retrospectively analyzed. Ninety percent of them received craniospinal irradiation (CSI). All children received platinum-based chemotherapy. Survival analysis was conducted using the Kaplan-Meier estimate. The prognostic factors were analyzed by log-rank test.Results:The primary sites were pineal gland, sellar / suprasellar region and basal ganglia. The median age of onset was 108 months (20-204 months). The median follow-up time was 33 months (8-131 months), and the 3-year and 5-year overall survival (OS) rates were 82.0%. The 3-year and 5-year progression-free survival (PFS) rates were 78.6% and 73.0%. Univariate analysis showed that increased alpha-fetoprotein (AFP) ( P=0.02), age at first diagnosis>10 years ( P=0.006), metastasis at first diagnosis ( P<0.001), and the pathological type (choriocarcinoma, yolk sac tumor and / or embryonal carcinoma) ( P=0.036) were independent adverse prognostic factors. Conclusions:Increased AFP, age>10 years at first diagnosis, tumor metastasis and pathological type were independent adverse prognostic factors of NGGCT. The overall prognosis of NGGCT children is worse than that of their counterparts with germinoma, and multidisciplinary intensive therapy is needed to improve survival.

Objective:To analyze the clinical efficacy and prognostic factors of comprehensive treatment for atypical teratoid / rhabdomyoma tumor (AT/RT).Methods:Clinical data of children diagnosed with AT/RT who underwent radiotherapy in Department of Oncology of Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2012 to September 2022 were retrospectively analyzed. Pearson Chi-square test or continuous-corrected Chi-square test or Fisher's exact probability method were used for inter-group comparison of categorical variables. Independent sample t-test or Wilcoxon rank-sum test were used for inter-group comparison of continuous variables. Kaplan-Meier method was used to calculate the 1-year and 2-year overall survival (OS) rate and progression free survival (PFS) rate. Univariate and multivariate Cox regression analyses were employed to determine relevant prognostic factors. Results:A total of 45 patients were included, with a male/female ratio of 1.65:1, including 27 children aged ≥3 years old. All patients received surgery and radiotherapy in which 39 patients received chemotherapy, 41 craniospinal irradiation (CSI), and 4 whole brain or focal radiation therapy. The median follow-up was 28 (13.5, 49) months. A total of 14 patients died after comprehensive treatment. The 1-year OS rate was 80.0% and the PFS rate was 71.1%. The 2-year OS rate was 75.5% and the PFS rate was 65.7%. Survival prognostic analysis showed negative imaging assessment after radiotherapy ( HR=0.087, 95% CI: 0.011-0.697, P=0.022) was a favorable factor for PFS. The primary tumor<4.8 cm ( HR=0.221, 95% CI: 0.052-0.935, P=0.040) and CSI ( HR=0.085, 95% CI: 0.011-0.651, P=0.018) were favorable factors for OS. In subgroup analysis, CSI also improved OS in children aged ≥3 years ( HR=0.014, 95% CI: 0-0.470, P=0.017), but there was no significant difference in PFS. In children without cerebrospinal fluid dissemination, negative radiographic results after radiotherapy ( HR=0.066, 95% CI: 0.009-0.481, P=0.007; HR=0.076, 95% CI: 0.008-0.695, P=0.024, respectively) and CSI (HR=0.105, 95% CI: 0.012-0.937, P=0.044; HR=0.054, 95% CI: 0.005-0.629, P=0.020, respectively) were favorable factors for PFS and OS in children, and the primary tumor<4.8 cm also suggested a longer OS ( HR=0.094, 95% CI: 0.013-0.690, P=0.020). Conclusions:Comprehensive treatment including radiotherapy improves clinical prognosis of children with AT/RT. Our study shows that negative imaging results after radiotherapy are associated with PFS improvement. The primary tumor<4.8 cm and CSI are favorable factors for OS. CSI is also a significantly positive prognostic factor in children aged ≥3 years and those without cerebrospinal fluid dissemination.

OBJECTIVES:
The aim of this study was to evaluate the disease burden of prostate cancer (PC) and assess key influencing factors associated with the disease expenditures of PC in the United States.
METHODS:
The total deaths, incidence, prevalence, and disability-adjusted life-years of PC were obtained from the Global Burden of Disease Study 2019. The Medical Expenditure Panel Survey was used to estimate healthcare expenditures and productivity loss and to investigate patterns of payment and use of healthcare resources in the United States. A multivariable logistic regression model was conducted to identify key factors influencing expenditures.
RESULTS:
For patients aged 50 and older, the burden for all age groups showed a modest increase over the 6-year period. Annual medical expenditures were estimated to range from US$24.8 billion to US$39.2 billion from 2014 to 2019. The annual loss in productivity for patients was approximately US$1,200. The top 3 major components of medical costs were hospital inpatient stays, prescription medicines, and office-based visits. Medicare was the largest source of payments for survivors. In terms of drug consumption, genitourinary tract agents (57.0%) and antineoplastics (18.6%) were the main therapeutic drugs. High medical expenditures were positively associated with age (p=0.005), having private health insurance (p=0.016), more comorbidities, not currently smoking (p=0.001), and patient self-perception of fair/poor health status (p<0.001).
CONCLUSIONS
From 2014 to 2019, the national real-world data of PC revealed that the disease burden in the United States continued to increase, which was partly related to patient characteristics.

To analyze the clinical outcomes of emergency percutaneous intervention in acute myocardial infarction (AMI) during hospital, and to find the relevant risk factors for the prognosis and cardiac events.
Methods: We retrospective analyzed the patient with acute ST segment elevation myocardial infarction, who was successfully performed emergency percutaneous coronary intervention (PCI) in the Cardiac Cath Lab of the Second Xiangya Hospital from January 2010 to December 2014. According to situation for cardiovascular events, patients were divided into 2 groups. The clinical factors were compared between the 2 groups.
Results: The incidence of adverse event was 22% (67/304). By using t test and χ2 analysis, we found that Cr, NT-proBNP, HCT, WBC, age>75, Killip grade≥2, TIMI flow after PCI≤2, arrhythmia, multi-vessel lesion, ST-segment resolution≥50%, long D2B time are statistically different between the 2 groups. Logistic analysis revealed that HCT, NT-proBNP, Killip grade≥2, TIMI flow after PCI≤2, ST-segment resolution≥50%, long D2B time were important predictors for cardiac events in-hospital.
Conclusion: HCT, NT-proBNP, Killip grade≥2, TIMI flow after PCI≤2, ST-segment resolution≥50%, long D2B time are important predictors for cardiac events in-hospital. The prognosis for AMI patient after emergency PCI could be improved and the incidence of cardiac event in hospital could be reduced if the high risk factors can be properly handled.

This paper summarized the clinical experience of Professor HE Chengyao in treating recurrent miscarriage complicated with subclinical hypothyroidism. It is believed that kidney yang insufficiency is the root of the disease, while the functional decline of the five zang (脏) organs and the obstruction of the sanjiao (三焦) pivot are the key links of the pathogenesis. In clinical practice, the division of yang numbers in the Book of Changes (《周易》) is followed, and 9 months is advocated as the basic treatment cycle for recurrent miscarriage complicated with subclinical hypothyroidism. During the first half of the period before pregnancy (the first 3 months), it is recommended to warm the pivot and sanjiao (三焦), and Yougui Pills (右归丸) is commonly used as the basic prescription to warm and supplement the kidney yang, together with the medicinals of invigorating blood and dissolving stasis, regulating and unblocking qi movement. During the second half of the period before pregnancy (the second 3 months), it is better to nourish essence and nature the embryo commonly with Wuzi Yanzong Pills (五子衍宗丸) in modification. After pregnancy (the third 3 months), it is suggested to supplement kidney and consolidate chong mai (冲), replenish qi and nourish blood mainly, supplemented by warming and nourishing heart yang, and self-made Bushen Antai Formula (补肾安胎方) which is modified based on the combination of Shoutai Pills (寿胎丸) and Wenbao Beverage (温胞饮) is commonly used.Additionally, it is recommended to adjust lifestyle and diet so as to balance yin and yang and improve the physical condition.

Objective:To analyze the association between zygomatic change and bone setback or resection and propose a quantitative guidance for L-shaped reduction malarplasty by linear regression analysis based on computed tomographic (CT) scan images.Methods:A retrospective observational study was conducted on patients who underwent L-shaped reduction malarplasty with mortice and tenon joint at the zygomatic arch in Department of Orthognathic and Temporomandibular Joint Surgery, West China Hospital of Stomatology, Sichuan University from January 2017 to September 2022. Bone setback and resection were performed in cases required a classical L-shaped osteoectomy with oblique bone resection (Group Ⅰ). Bone setback was performed in cases required a modified L-shaped osteotomy without bone resection (Group Ⅱ). Wound healing and the occurrence of complications were followed up after operation. The amount of bone setback and resection were calculated by using preoperative and postoperative CT scan images. The unilateral width changes of the anterior, middle, and posterior zygomatic regions(ΔZBP-MFP, ΔZMP-MFP, ΔZAP-MFP, respectively) as well as zygomatic protrusion change(Δzygomatic protrusion) were also evaluated. SPSS 20.0 software was used for statistical analysis. The measurement data was expressed as Mean±SD. Zygomatic width and protrusion change of the two groups was compared by independent t-test. Comparison of complication rates between the two groups was performed using the χ2 test. Correlation analysis using Pearson correlation coefficients was performed between bone resection or setback and zygomatic width or protrusion change. Linear regression analysis was also performed. Results:A total of 80 patients were enrolled. Group Ⅰ consisted of 40 patients [6 males and 34 females; aged (25.2±3.8) years, ranging from 19 to 33 years] who underwent a classical L-shaped osteotomy with both bone setback and resection, while Group Ⅱ consisted of 40 patients [10 males and 30 females; aged (26.0±3.0) years, ranging from 20 to 35 years] who underwent a modified L-shaped osteotomy with bone setback but without bone resection. All patients healed uneventfully during the follow-up period[(12.5±3.3) months, ranging from 5 to 20 months]. There was no significant difference in the incidence of complications such as infection, transient paresthesia, severe swelling and hematoma between the two groups ( P>0.05). No severe complications, such as facial asymmetry, sagging cheek, bone nonunion, were observed. All patients significantly improved facial contours. There was a statistically significant difference (all P<0.01) in ΔZBP-MFP [ (2.52±0.76) mm vs. (1.85±0.40) mm], ΔZMP-MFP [ (3.30±0.54) mm vs. (2.94±0.51) mm] and Δzygomatic protrusion [ (4.42±1.20) mm vs. (3.59±0.84) mm] between Group Ⅰ and Group Ⅱ. No statistical difference was found in ΔZAP-MFP ( P>0.05). Significant correlation was observed between the bone setback or resection and the changes of anterior, middle zygomatic width as well as protrusion in both the two groups ( r=0.60-0.92, all P<0.01), and the linear regression equation was established. The correlation between bone setback or resection and the posterior zygomatic width change was not significant ( P>0.05). Conclusion:There are linear correlations between the unilateral anterior, middle zygomatic width change, zygomatic protrusion change and the unilateral bone setback or resection. The linear regression equations can be used as a quantitative guidance for preoperative surgical planning.
