Objective: To analyze the features of unhealthy lifestyle patterns among primary and secondary school students in the nutrition improvement program for rural compulsory education students (NIPRCES) areas in China in 2021 and 2023, so as to provide data support for lifestyle promotion and healthy development among primary and secondary school students. Methods: Adopting a cluster random sampling method, data on primary and secondary students aged 7-15 years from nutrition and health surveillance of China NIPRCES in 2021 and 2023 were collected. The prevalence of unhealthy lifestyles among primary and secondary students such as physical inactivity, outdoor inactivity, excessive screen time, and sleep deprivation by gender, school section, urban/rural, and region were analyzed. The reporting rates of the above indicators among primary and secondary students were compared by Chi-square test. Results: In 2021 and 2023, the rates of moderate to vigorous physical inactivity among primary and secondary school students were 79.2% and 80.4%, the rates of outdoor inactivity were 42.8% and 49.3%, the rates of excessive video time were 2.6% and 2.9%, the rates of sleep deprivation were 32.9% and 22.6%, and the differences were statistically significant( χ 2=51.86,1 071.48,18.36,3 296.99, P <0.05). In 2023, the rate of outdoor inactivity for primary and secondary students increased by 6.5 percentage points compared with 2021, and the rate of sleep deprivation decreased by 10.3 percentage points compared with that in 2021. In 2021 and 2023, the reporting rates of moderate to vigorous physical inactivity, outdoor inactivity, and sleep deprivation among girls and junior high school students were higher than those among boys ( χ 2=174.41,180.11; 175.75, 85.46 ;92.22,151.35) and elementary school students ( χ 2=136.64,5.75; 40.55,4.71;162.80,3 291.61); the reporting rates of moderate to vigorous physical inactivity( χ 2=194.43,118.60) and sleep deprivation ( χ 2=969.66,983.72) among urban students were higher than those among rural students; the reporting rates of excessive video time for boys and junior high school students were higher than those for girls ( χ 2=103.62,84.85) and elementary school students ( χ 2=810.09,626.51)( P <0.05). From a regional distribution perspective, the reporting rates of moderato to vigorous physical inactivity, outdoor inactivity, and excessive video time among primary and seconday school students in the central and western regions were lower than those in the eastern region ( χ 2= 663.44,302.78; 356.97,82.10;50.89,81.83) ( P <0.05). Conclusions Unhealthy lifestyles remain prevalent among primary and secondary students in NIPRCES areas of China. These findings underscore the need to strengthen policy implementation for promoting healthy lifestyles among primary and secondary school students.

Objective: To understand the prevalence and related factors of depressive symptoms among primary and secondary school students in the in depth monitoring counties of China s Rural Compulsory Education Nutrition Improvement Program, so as to provide a basis for prevention and psychological intervention of depressive symptoms among children and adolescents in rural areas. Methods: In November 2022, a stratified random sampling method was adopted to collect height and weight data, basic personal and family information of 7 949 primary and secondary school students from grade three to grade nine through physical measurements and questionnaires in 56 key monitoring schools implementing the Student Nutrition Improvement Program in 7 in depth monitoring counties (Jalaid Banner in Inner Mongolia, Jinzhai County in Anhui, Mao Xian in Sichuan, Tiandeng County in Guangxi, Mian County in Shaanxi, Zhaozhou County in Heilongjiang and Youxi County in Fujian), and to obtain the information related to their depressive symptoms through the self assessment questionnaire on depression. Multivariate Logistic regression analysis was conducted to analyze the prevalence of depressive symptoms among primary and secondary school students, as well as their related factors. Results: The detection rate of depressive symptoms among primary and secondary school students in the in depth monitored counties was 23.5%. Logistic regression analysis showed that the probability of detecting depressive symptoms was higher among female students, middle school students, students whose video screen duration per day was >2 h, and students whose parents marital status was divorced or widowed ( OR =1.40, 1.64, 1.60, 1.24), and students whose sleep duration reached the recommended standard, whose parents usually accompanied them daily for time was 60-<120 min and ≥120 min, and students whose mothers literacy level was middle school graduation had lower probability of detecting depressive symptoms ( OR =0.85, 0.84, 0.71, 0.76) ( P < 0.05 ). Conclusion The detection rate of depressive symptoms among students in the in depth monitoring area is high, and targeted interventions need to be developed for students to reduce the risk of mental health problems.

Objective:To investigate the changes of thyroid hormones and the flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyrotoxicosis before and after treatment with methimazole.Methods:A case-control study was conducted to select 45 cases of Graves' disease and 45 cases of Hashimoto's thyroiditis from October 2021 to December 2022 in the Department of Endocrinology, North China University of Science and Technology Affiliated Hospital. The changes of thyroid hormone and blood flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyroiditis before and after treatment with methimazole were analyzed. Measurement data satisfying normal distribution were expressed by xˉ±s, and the mean between two groups was compared by t test. Measurement data not satisfying normal distribution were expressed by M( Q1, Q3), and the median between two groups was compared by Wilcoxon rank sum test. χ 2 test was used to compare the constituent ratio of enumeration data among groups. Results:There was no significant difference in thyroid stimulating hormone (TSH) between the two groups before treatment, and there was no significant difference in TSH between the two groups after 1 month and 3 months of treatment (all P>0.05). The levels of free triiodothyronine (FT3) were (24.09±9.29) pmol/L and (17.41±9.36) pmol/L in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. FT4 were (60.23±20.82) and (43.47±21.71) pmol/L, respectively, and the peak stolie vloiy (PSV) were (69.53±5.70) and (52.65±4.64) cm/s, respectively in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. There were significant differences between the two groups ( t values wrere 3.39 and 3.74, Z=13.83, all P<0.001). The difference of FT3 between one month after treatment and before treatment was (-6.36±5.32) and (-12.64±9.08) pmol/L ( t=4.02, P<0.001) and the difference in FT3 between 3 months of treatment and before treatment was (-10.14±9.50) and (-17.80±11.17) pmol/L, respectively ( t=3.51, P<0.001) between the Graves disease group and the Hashimoto's thyroiditis group. The difference in FT4 between the Graves disease group and the Hashimoto's thyroiditis group after 1 month of treatment and before treatment was (-28.47±10.09) and (-20.57±14.48) pmol/L ( t=7.01, P<0.001), and the difference of FT4 was (-47.06±20.57) and (-30.17±20.54) pmol/L ( t=3.91, P<0.001) between the Graves disease group and the Hashimoto toxin group. The difference between one month after treatment and before treatment was (-13.10(-34.10,-2.60)) and (-10.50(-27.5,-0.20)) cm/s ( Z=2.63, P=0.009), respectively. The difference between 3 months and before treatment was (-31.40(-53.20,-12.70)) and (-19.90(-46.00,-4.70)cm/s ( Z=4.40, P<0.001)) between the Graves disease group and the Hashimoto's thyroiditis group, and the difference was statistically significant. Conclusion:Thyroid hormone levels were decreased after treatment with methimazole in patients with diffuse toxic goiter and Hashimoto toxemia, but the difference was not statistically significant. The PSV level of superior thyroid artery in patients with diffuse toxic goiter was significantly lower than that in patients with Hashimoto's thyrotoxicosis.

Objective:To explore the effect of variable priority cognitive-motor dual-task training in aged cognitive frailty patients with type 2 diabetes mellitus.Methods:From September 2022 to September 2023, a total of 108 aged cognitive frailty patients with type 2 diabetes mellitus were selected in the Department of Endocrinology of North China University of Science and Technology Affiliated Hospital as research subjects.The subjects were divided into three groups in the order of admission, with 36 people in each group.Three groups of patients were intervened for 8 weeks using variable priority cognitive-motor dual-task training (VP group), exercise combined cognitive intervention with sequential task (ST group), and endocrinology routine treatment and nursing (control group), respectively.The scores of mini-mental state examination(MMSE), frailty phenotype(FP) and Berg balance scale(BBS) were compared among the three groups before and after the intervention.Repeated measurement variance analysis was used to compare scale results by SPSS 22.0.Results:(1)The MMSE score of patients before and after intervention had significant interaction effect between time and groups ( F=69.929, P<0.05).The MMSE scores of the VP group and ST group after 8 weeks of intervention were higher than those before intervention and after 4 weeks of intervention, and the MMSE scores of the two groups after 4 weeks of intervention were also higher than those before intervention (all P<0.05).After 4 weeks and 8 weeks of intervention, the MMSE score of the VP group was higher than that of the ST group and the control group, and the MMSE score of the ST group was higher than that of the control group after 8 weeks of intervention(all P<0.05).(2)The FP score of patients before and after intervention had a significant interaction effect between time and groups ( F=46.425, P<0.05).The FP score of the VP group at 8 weeks of intervention (2.64±0.59) was lower than that after 4 weeks of intervention (3.28±0.51) and before intervention (3.56±0.61), and the FP score after 4 weeks of intervention was lower than before intervention (all P<0.05).The FP score of the ST group after 8 weeks of intervention (3.44±0.56) was lower than before the intervention (3.59±0.56) ( P<0.05); After 4 weeks of intervention, the FP score of the VP group was lower than that of the control group (3.36±0.54) ( P<0.05).After 8 weeks of intervention, the FP score of the VP group was lower than that of the ST group and the control group (3.39±0.55) (both P<0.05).(3)The FP score of patients before and after intervention had a significant interaction effect between time and groups ( F=135.791, P<0.05).The BBS scores of the VP group and ST group after 8 weeks of intervention were higher than those before and after 4 weeks of intervention, and the BBS scores after 4 weeks of intervention were also higher than those before intervention (all P<0.05).After 4 weeks of intervention, the BBS score of the VP group was higher than that of the control group ( P<0.05).After 8 weeks of intervention, the BBS score of the VP group was higher than that of the ST group and the control group, and the BBS score of the ST group was also higher than that of the control group (all P<0.05). Conclusion:The variable priority cognitive-motor dual-task training can improve the cognitive function, physical frailty and balance function in aged cognitive frailty patients with type 2 diabetes mellitus, and the intervention effect is better than that of exercise combined cognitive intervention with sequential task and endocrinology routine treatment and nursing.

Objective:To explore the role of first-aid network construction in the early treatment of patients with critically severe hydrofluoric acid burns.Methods:Twenty-seven fluorine chemical enterprises distributed in Zhejiang province, Jiangxi Province, Fujian Province, and Inner Mongolia Autonomous Region and 22 hospitals with burn/plastic department or professional burn treatment group in Zhejiang province, including Zhejiang Quhua Hospital, and 5 hospitals outside Zhejiang province were involved in the first-aid network construction as member units. As the main unit, Zhejiang Quhua Hospital was responsible for the daily maintenance and technical guidance of the first-aid network. Zhejiang Quhua Hospital was assigned as the designated emergency hospital for 20 fluorine chemical enterprises, a near emergency hospital to the other 7 fluorine chemical enterprises was assigned as the designated hospital for them. Medical records of 56 patients (all males) with critically severe hydrofluoric acid burns who admitted to 5 first-aid network hospitals from January 2006 to June 2021, meeting the inclusion criteria, were involved in the retrospective cohort study. Based on whether the enterprise belonging to the first-aid network construction or not, the patients were divided into first-aid network group (27 cases, aged (41±9) years) and non first-aid network group (29 cases, aged (42±10) years). After the patients in the first-aid network group were injured, the enterprises and hospitals linked up immediately. The hospital where the patient was treated mobilize the treatment force, equipment, materials, and drugs in advance by the first-aid network, thereby realizing seamless joint between pre-hospital first-aid and in-hospital treatment. The hospital started the first-aid process and temporarily mobilized the rescue forces, equipment, materials, and drug after patients in non first-aid network group arrived at the department of emergency of the hospital. The time from injury to medical service, the first detection time of serum calcium, the time staying in department of emergency, the duration of hypocalcemia and hypomagnesemia, and the treatment outcome of patients in the two groups were recorded. Data were statistically analyzed with chi-square test, Fisher's exact probability test, independent-sample t test, and Wilcoxon rank-sum test. Results:The time from injury to medical service, the first detection time of serum calcium, and the time staying in department of emergency of patients in first-aid network group were 40.0 (30.0, 55.0), 23.0 (17.5, 37.5), and 42.0 (37.0, 53.0) min, which were significantly shorter than 180.0 (120.0, 240.0), 31.0 (22.5, 47.5), 61.0 (52.0, 65.5) min in non first-aid network group ( Z=-6.17, -1.98, -4.15, P<0.05 or P<0.01). The duration of hypocalcemia and hypo- magnesemia of patients in first-aid network group were 1.2 (1.1, 1.6) and 1.9 (1.7, 2.1) h, which were significantly shorter than 4.6 (3.1, 6.2) and 3.2 (2.5, 4.6) h in non first-aid network group ( Z=-5.80, -4.81, P<0.01). Three patients (11.1%) in first-aid network group died, among whom 2 patients died at 40 min after injury and 1 patient died 9.0 h after injury. Four patients (13.8%) died in non first-aid network group at 3.0, 3.0, 4.5, and 7.0 h after injury, respectively. The mortality rates of patients in the two groups were similar ( P>0.05). Conclusions:Critically severe hydrofluoric acid burn is an extremely urgent situation encountered in clinical practice. The construction of a first-aid network creates condition for on-site treatment of patients and improves the first-aid efficiency, thereby gaining time to save lives.

Objective To observe the changes of serum ferritin and 25-(OH) vitamin D3 in patients with diabetic cranial neuropathy.Methods There were 50 patients without diabetic Cranial neuropathy,46 patients with diabetic cranial neuropathy,and 40 cases of normal control group.The changes of serum ferritin and 25-hydroxy vitamin D3 were observed in each group.The correlation between two indexes and the correlation with diabetic cranial neuropathy were analzyzed.Results The serum ferritin levels in diabetic group and diabetic neuropathy group were significantly higher than those in normal control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(687.54 ± 65.38)ng/ml] was significantly higher than that of patients without diabetic cranial neuropathy [(497.28 ± 46.39) ng/ml,P ＜0.01].The serum 25-(OH) vitamin D3 levels in the diabetic group and diabetic neuropathy group were lower than those in the control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(26.45 ± 8.93)nmol/l] was significantly less than that of patients without diabetic cranial neuropathy [(37.19-± 9.74)nmol/L,P ＜ 0.01].Serum ferritin levels were positively correlated with 25-(OH) vitamin D3 (r =-0.59,P ＜ 0.01).Multivariate unconditional Logistic regression analysis showed that diabetic neuropathy was negatively correlated with 25-(OH) vitamin D3 (P ＜ 0.05).Conclusions The increases of serum ferritin and 25-(OH) vitamin D3 are closely related to the occurrence and development of diabetic cranial neuropathy,which provides the theoretical basis for clinical intervention therapy.

Objective To investigate the relationship among health literacy and treatment compliance and prognosis in patients with diabetes combined tuberculosis.Methods One hundred and eighty-one cases patients with diabetes combined tuberculosis were selected as the objectives and evaluated literacy level,compliance scale by the health literacy scale and compliance questionnaires.The control of tuberculosis,blood glucose control,treatment compliance and prognosis were analyzed in the patients with different health literacy level.Results Of 181 patients,there were 89 cases patients'(basic health literacy group) the total scores of health literacy and compliance were＞80 points,the efficacy of pulmonary tuberculosis control and blood sugar control were respectively 84.2％ (75/89) and 93.2％ (83/89);92 cases patients' the total scores of health literacy and compliance were ≤ 80 points,the efficacy of pulmonary tuberculosis control and blood sugar control were respectively 59.7％ (55/92) and 67.4％ (62/92),the differences were significant (x2 =12.78,18.11;P ＜0.05).Pearson correlation analysis showed that the total scores of health literacy were positive correlated with the scores of treatment compliance (r =0.688,P ＜ 0.001).Logistic regression analysis showed that three dimension of health literacy (health knowledge and concept,healthy lifestyle and behavior,health skills) that can combined predict the variance of rehabilitation compliance(P＜0.01).Conclusion The health literacy level of diabetes combined tuberculosis patients can effectively predict the rehabilitation compliance.Measures should be taken to improve the patient's level of health literacy,so as improve the compliance of rehabilitation and prognosis.

Objective To investigate the changes of serum ferritin and homocysteine of diabetic patients,to explore its correlation with diabetic gastroparesis.Methods Pure 50 patients with diabetes,50 patients with diabetic gastroparesis,and 50 cases of normal control group were chosen.The serum ferritin levels were measured with chemiluminescence method,the serum homocysteine levels were measured with enzyme linked immunosorbent assay (ELISA) method.The changes of serum ferritin and serum homocysteine in each groups were observed.Its relationship with diabetic gastroparesis was studied.Results For all diabetic patients,the serum ferritin and homocysteine levels were significantly higher than those in normal control group (P ＜ 0.01).Patients with diabetic gastroparesis was higher than those of pure diabetes (P ＜ 0.01).Serum ferritin levels was positively correlated with glycosylated hemoglobin and homocysteine (r =0.62,0.78,P ＜ 0.01).Multi-factor analysis showed that serum ferritin,and homocysteine level was positively associated with diabetic gastroparesis (P ＜ 0.05).Conclusions The increases of serum ferritin and homocysteine levels were closely related to the occurrence and development of diabetic gastroparesis.They can be used as one of parameters of diabetic gastroparesis,and provide theoretical basis for clinical intervention therapy.
