Objective: To explore the relationship between junior high school students lifestyles and 20 m shuttle run test (20 m SRT) performance, so as to provide a theoretical basis for promoting a healthy lifestyle among junior high school students. Methods: From April to June 2021, a total of 2 397 junior high school students aged 12-17 years in Yushan, Wuyuan, Hengfeng and Yugan counties of Shangrao City, Jiangxi Province were selected by random cluster stratified sampling. A questionnaire survey and 20 m SRT test were conducted. Logistic regression analysis was used to explore the association between lifestyles and 20 m SRT scores. Results: The passing rate of 20 m SRT for middle school students was 83.3%. Chi square test results showed that there were statistically significant differences between gender, grade, household registration, type of schooling, father s education and the 20 m SRT scores of junior high school students ( χ 2=25.26, 25.04, 6.99, 7.96, 16.22, P <0.05). Significant differences were found in 20 m SRT scores between vigorous and moderate physical activity and breakfast behavior in the last seven days ( χ 2=6.78, 6.29, 9.13, P < 0.05). The results of Logistic regression analysis showed that after controlling for confounding factors, "no vigorous physical activity in the last seven days" was positively correlated with the lower performance of 20 m SRT ( OR =1.31, 95% CI =1.03- 1.67 , P < 0.05). "Breakfast skipping" was positively correlated with 20 m SRT lower performance (frequent eating, OR =1.37, 95% CI = 1.09 -1.73, P <0.01). Conclusion Vigorous physical activity and regular breakfast consumption behavior are associated with higher performance 20 m SRT of junior high school students. Schools should encourage students to develop a habit of actively exercising and consuming breakfast regularly in order to ensure the healthy development of cardiopulmonary endurance levels.

Objective:To evaluate the effect of hierarchical diagnosis and treatment model of childhood bronchial asthma in Shanghai Pudong New Area.Methods:According to the principle of proximity, children aged 6 months-17 years who were diagnosed with bronchial asthma at Shanghai Children′s Medical Center from July 2016 to May 2017 were divided into two cohorts: the specialized hospital group and the community hospital group.Twelve months of treatment and follow-up were conducted.The asthma control level, Childhood Asthma Control Test (C-ACT) score, medication adherence and health economic indicators were collected.Results:A total of 524 children were included for data analysis and divided into the specialized hospital group (300 cases) and the community hospital group (224 cases). According to the Global Initiative for Asthma(GINA) criteria, there was no statistical difference in monthly asthma control level between the two groups (all P>0.05). In the 12 th month, the well-controlled rate of the specialized hospital group increased by 12.4% ( P<0.01), and that of the community hospital group increased by 22.9% ( P= 0.015). According to the C-ACT criteria, there was no statistical difference in the monthly well-controlled rate between the two groups (all P>0.05), and the rate maintained an upward trend.The rates of patients with good compliance in the specialized hospital group and the community hospital group at the 12 th month of hierarchical diagnosis and treatment were 78.3%(235/300 cases) and 75.0%(168/224 cases), respectively, and the difference was not statistically significant ( P=0.370). After 12 months of hierarchical diagnosis and treatment, the number of asthma attacks were 1.0 and 2.0 ( P=0.269), and the hospitalization rates for asthma were 3.0%(9/300 cases) and 4.9%(11/224 cases), respectively in the specialized hospital group and the community hospital group, and the diffe-rence was not statistically significant ( P=0.259); the number of respiratory infections in the specialized hospital group (2.0 times) was lower than that in the community hospital group (3.0 times), and the total cost of treatment in the community hospital group (2 471.5 Yuan) was lower than that in the specialized hospital group (3 445.5 Yuan), and the difference was statistically significant ( Z=-3.308, -3.336, all P<0.01). Twelve months after hierarchical diagnosis and treatment, the number of asthma attacks, the number of respiratory infections and the hospitalization rate for asthma in the two groups were all lower than those in the first 12 months of hierarchical diagnosis and treatment, and the difference was statistically significant (all P<0.01). Conclusions:Hierarchical diagnosis and treatment model of childhood asthma in Shanghai Pudong New Area can improve asthma control level, C-ACT score and asthma medication adherence, and enhance health economic benefits, thus it′s an effective way to manage childhood asthma.

Objective To assess the efficiency and safety of the bronchoscopic CO2cryotherapy to remove bronchial foreign body in children. Methods From Oct 2012 to Dec 2016, 8 cases diagnosed with the presence of bronchial foreign body were undergone the treatment with the bronchoscopic CO2cryotherapy. The clinical data about the efficiency and complication were collected and retrospectively analyzed. Results In the 8 cases, we successfully removed the bronchial foreign bodies without complications. In 2 cases, the foreign bodies were removed successfully, but cryotherapy partially damaged the airway mucosa, causing topical airway obstruction because of the newly developed granulation tissue. No serious adverse reactions or complications were observed after the treatment. Conclusions Removal of bronchial foreign bodies using bronchoscopic CO2 cryotherapy is an easy and effective method which can be used as a supplementary procedure for the bronchoscopic removal of foreign bodies in children's airways.

OBJECTIVE: To determine the incidence of surgical site infection (SSI) after abdominal surgery and to further evaluate the related risk factors of SSI in China. METHODS: The multicenter cross-sectional study collected clinical data of all adult patients who underwent abdominal surgery from May 1, 2018 to May 31, 2018 in 30 domestic hospitals, including basic information, perioperative parameters, and incisional microbial culture results. The primary outcome was the incidence of SSI within postoperative 30 days. SSI was classified into superficial incision infection, deep incision infection, and organ/gap infection according to the US Centers for Disease Control and Prevention (CDC) criteria. The secondary outcome variables were ICU stay, postoperative hospital stay, total hospital stay, 30-day mortality and treatment costs. Multivariate logistic regression was used to analyze the risk factors of SSI. RESULTS: A total of 1666 patients were enrolled in the study, including 263 cases of East War Zone Hospital of PLA, 140 cases of Affiliated Hospital of Qingdao University, 108 cases of The First Affiliated Hospital of Nanchang University, 87 cases of Central War Zone Hospital of PLA, 77 cases of West China Hospital, 74 cases of Guangdong General Hospital, 71 cases of Chenzhou First People's Hospital, 71 cases of Zigong First People's Hospital, 64 cases of Zhangjiagang First People's Hospital, 56 cases of Nanyang City Central Hospital, 56 cases of Lanzhou General Hospital of Lanzhou Military Command, 56 cases of Shandong Provincial Hospital, 52 cases of Shangqiu First People's Hospital, 52 cases of People's Hospital of Xinjiang Uygur Autonomous Region, 48 cases of The Second Xiangya Hospital of Central South University, 48 cases of Chinese PLA General Hospital, 44 cases of Affiliated Hospital of Xuzhou Medical University, 38 cases of Hunan Province People's Hospital, 36 cases of Dongguan Kanghua Hospital, 30 cases of Shaoxing Central Hospital, 30 cases of Northern Jiangsu People's Hospital, 29 vases of The First Affiliated Hospital of Zhengzhou University, 27 cases of General Hospital of Tianjin Medical University, 22 cases of Zigong Fourth People's Hospital, 21 cases of The Second Hospital of University of South China, 18 cases of Tongji Hospital, 15 cases of Nanchong Central Hospital, 12 cases of The 901th Hospital of PLA, 11 cases of Hunan Cancer Hospital, 10 cases of Lanzhou University Second Hospital. There were 1019 males and 647 females with mean age of (56.5±15.3) years old. SSI occurred in 80 patients (4.8%) after operation, including 39 cases of superficial incision infection, 16 cases of deep incision infection, and 25 cases of organ/interstitial infection. Escherichia coli was the main pathogen of SSI, and the positive rate was 32.5% (26/80). Compared with patients without SSI, those with SSI had significantly higher ICU occupancy rate [38.8%(31/80) vs. 13.9%(220/1586), P<0.001], postoperative hospital stay (median 17 days vs. 7 days, P<0.001) and total hospital stay (median 22 days vs. 13 days, P<0.001), and significantly higher cost of treatment (median 75 000 yuan vs. 44 000 yuan, P<0.001). Multivariate analysis showed that male rise(OR=2.110, 95%CI:1.175-3.791, P=0.012), preoperative blood glucose level rise(OR=1.100, 95%CI: 1.012-1.197, P=0.026), operative time (OR=1.006, 95%CI:1.003-1.009, P<0.001) and surgical incision grade (clean-contaminated incision:OR=10.207, 95%CI:1.369-76.120, P=0.023; contaminated incision: OR=10.617, 95%CI:1.298-86.865, P=0.028; infection incision: OR=20.173, 95%CI:1.768-230.121, P=0.016) were risk factors for SSI; and laparoscopic surgery (OR=0.348, 95%CI:0.192-0.631, P=0.001) and mechanical bowel preparation(OR=0.441,95%CI:0.221-0.879, P=0.020) were protective factors for SSI. CONCLUSIONS The incidence of postoperative SSI in patients with abdominal surgery in China is 4.8%. SSI can significantly increase the medical burden of patients. Preoperative control of blood glucose and mechanical bowel preparation are important measures to prevent SSI.

Objective To understand the status of implementation of invasive ventilator circuit changes in ICU nurses at the 3A general hospitals in Shanxi Province, and mastering and demand of related knowledge of ICU nurses, and by this discuss the possible causes of execution inconsistency in invasive ventilator circuit changes interval so as to provide a clear basis for the specification and circuit changes. Methods After a review of relevant literature at home and abroad as well as expert consultation, a self-designed questionnaire was established, take two ways of on-site issuance and mailing, ICU nurses from 13 hospitals were selected randomly to investigate about the invasive circuit changes interval in Shanxi Province. Results A total of 724 nurses from 34 ICU of 13 hospitals were surveyed. A unified circuit changes interval of ICU accounted for 73.5% (527/717). ICU nurses currently provisions and practical implementation of invasive ventilator circuit changes interval tend to 7 d. Different ICU provisions and ICU nurses actual implementation of circuit change were significantly different (χ2=24.839, 35.760, P < 0.01). Conclusions Hospitals should choose the right way to strengthen the ICU nurses invasive ventilator circuit changes training interval and knowledge, to develop the term for their own security environment, thereby reduce the workload of nurses, reduce medical costs and improve care service quality.

Objective To investigate the related risk factors of complicated parapneumonic effusion (CPPE) in children. Method The clinical data of 88 children with parapneumonic effusion (PPE) were retrospectively analyzed from January 2013 to April 2015. According to the treatment effect of antibiotics, CPPE group and uncomplicated parapneumonic effusion (UPPE) group were divided. The univariate analysis of clinical and laboratory parameters was performed between two groups. Then the multifactor logistic regression was performed further. The receiver operator characteristic (ROC) curve was draw. Results The univariate analysis indicated that the risk factors were the formation of loculation and serum CD3+ and CD19+ levels (Z=2.030~7.457, P<0.05). The multifactor logistic regression showed that the formation of loculation(OR=3.386, P=0.018) and serum CD19+levels (OR=4.000, P=0.009)were independent risk factors of CPPE. The area under the ROC curve (AUC) is 0.707, which indicated that the regression model had medium diagnostic accuracy (P=0.001). Conclusion CPPE may be developed in PPE children with the serum level of CD19+>30%and the formation of loculation.

Objective To explore the clinical characteristics of pleural effusion caused byMycoplasma pneumoniae in children.MethodsThe clinical data from children with pleural effusion caused byMycoplasma pneumoniae were retrospectively analyzed. Differences of clinical characteristics in children with pleural effusion caused byMycoplasma pneumoniae infection and non-Mycoplasma pneumoniae infection were compared. Moreover, multiple logistic regression analysis was performed on the factors that were identified to have statistical differences in single factor analysis. Receiver operating characteristic (ROC) curve was performed and the diagnostic boundary value of each factor and the diagnostic accuracy of the regression model were calculated.ResultsThere were statistical differences between children with pleural effusion caused byMycoplasma pneumoniae infection and by non-Mycoplasma pneumoniae infection in age, white blood cell count, lactic dehydrogenase (LDH), levels of IgA and IgM, and the proportion of multiple nuclei, glucose and lactic acid (LAC) in pleural effusion, pleural thickening, and formation of ifbrous separation (allP??3.92 years, serum IgM?>?1.29 g/L, LDH?>?367 U/L and pleural effusion LAC?

Objective To identify the relevant factors for the loculation clinically in children with parapneumonic pleural effusion (PPE).Methods The clinical data of 172 children with PPE were retrospectively reviewed from January 2012 to March 2015 in Children's Hospital of Hebei Province.Based on the findings of chest ultrasound, the subjects were divided into 2 groups, the loculation group (78 cases) and the control group (94 cases).The comparison was made between the 2 groups in gender, age, course of disease and fever before admitting into hospital, the location of the effusion, white blood cells (WBC) and the percentage of neutrophils (N), blood platelet (PLT) ,lactate dehydrogenase (LDH),C-reactive protein (CRP), mycoplasma (MP), the routine and biochemical examination of pleural fluid, including white cell count (WBCp), the percentage of polymorphonuclear cell (PMN), lactate dehydrogenase (LDHp) ,glucose (GLU) ,adenosine deaminase (ADA) ,lactic acid (LAC) and C-reactive protein (CRPp).If the result of single factor regression showed P ＜ 0.01, the indicators were analyzed by the multifactor Logistic regression.The receiver operator characteristic (ROC) curve was drawn to evaluate the prediction ability of Logistic regression models.Results (1) The result of single factor regression indicated that the risk factors included age, WBC, PLT, LDH, MP, WBCp, PMN, GLU and LAC (all P ＜ 0.05).(2) The result of multifactor Logistic regression showed that the factors included PLT (OR =3.437,P =0.007), LDH (OR =0.306, P =0.006), GLU (OR =0.324, P =0.037), MP (OR =0.375 ,P =0.022) and LAC (OR =3.656, P =0.003).(3) The area under the ROC curve was 0.876, P =0.000,which indicated that the regression models had over medium diagnostic accuracy.Conclusions When PLT ＞ 434.5 × 109/L,LDH ＜400 U/L,non MP infection,GLU ＜6.11 mmol/L and LAC ＞3.83 mmol/L,it may indicate that the formation of loculation for the PPE children.

Objective To evaluate the possible causes of misdiagnosis of minimal breast carcinoma (MBC). Meth-ods The possible causes of misdiagnosis of 90 cases of MBC confirmed by pathology were retrospective analyzed. Accord-ing to the maximum diameter of the lesion, 90 cases were divided into 0.5-1.0 cm group (n=55) and≤0.5 cm group (n=35). And these two groups were subdivided into correct and misdiagnosed groups. The two-dimensional ultrasound findings were observed by using SIEMENZ S2000, GE vivid7 and GE vivid9 color Doppler ultrasound instruments, and reasons of misdiag-nosis were analyzed. Results There were 32 cases were misdiagnosed in 90 patients with MBC. There was significant differ-ence in boundary of misdiagnosis between diameter 0.5-1.0 cm group and≤0.5 cm group. There were significant differences in boundary and calcification between misdiagnosed group and correct group in diameter 0.5-1.0 cm group (P<0.05). There were also significant differences in A/T ratio and accompanying by multiple benign nodules between misdiagnosed group and correct group in diameter≤0.5 cm group (P<0.05). Conclusion The misdiagnosis in MBC is because of different lesion sizes. The misdiagnosis happens in the maximum diameter of the lesions between 0.5-1.0 cm that showed manifestation of sharp edges, no micro-calcification in sonographic features of benign. The misdiagnosis happens in maximum diameter of le-sions≤0.5 cm that manifested as the aspect A/T ratio<1 and characterized by multiple nodules.
