Objective: To investigate the exposure to television advertising of sugar sweetened beverages and the use of persuasive marketing techniques among children and adolescents in Beijing, so as to provide evidence for reduing childrens intake of sugar sweetened beverages. Methods: From October 19, 2020 to November 16, 2021, 32 days were randomly selected. The top four popular channels of children and adolescents aged 3-18 years were defined. Each channel was monitored from 6:00:00 to 23:59:59 for each date. A total of 2 304 h was recorded. Advertisements involving sugar sweetened beverages broadcast before, during or after the program were included. The frequency and the use of persuasive marketing techniques were analyzed. Results: A total of 1 237 advertisements for sugar sweetened beverages were included, of which 50.93% were dairy beverages, 28.38% were teabased beverages, and 19.48% were vegetable protein beverages. The average frequency of sugar sweetened beverages advertisements on every channel was (0.62±1.29)piece/h. The frequency of sugar sweetened beverages advertisements on every local channel [(1.04±1.35)piece/h] and childrens channel [(1.11±1.61)piece/h] was separately higher than every national channel [(0.48±1.24)piece/h] and general channel [(0.12±0.48)piece/h] (t=-14.05, 31.64, P<0.01). There were seasonal differences in television advertising of sugar sweetened beverages, and were more frequent during lunch and dinner times. The most frequently used persuasive marketing techniques were "images of children" (74.54%), "nutritional message" (61.76%), "product composition details" (58.61%), "nutrition claim" (57.24%), and "nutrition function claim or other function claim" (53.11%). Conclusions Children and adolescents are often exposed to television advertisement of sugar sweetened beverages on childrens channels and during meal times. There is an urgent need to formulate relevant policies to regulate the marketing of sugar sweetened beverages advertisement and reduce children and adolescents intake.

Objective:To evaluate the value of curative effect in neuromyelitis spectrum disease (NMOSD) based on circulatory function evaluation of intracerebral glymphatic system by using diffusion tensor imaging analysis along the perivascular space.Methods:The clinical and imaging data of 23 patients diagnosed with NMOSD at Tianjin Medical University General Hospital from March 2018 to December 2019 were retrospectively analyzed in this study. The clinical data included expanded disability status scale (EDSS), average relapse rate (ARR) and retinal nerve fiber layer (RNFL) thickness at baseline and 1 year follow-up after treatment. Among the 23 NMOSD patients, there were 22 females and 1 male, aged from 21 to 71 (45±13) years old. All the patients underwent MR scans at both baseline and 1 year after treatment, and the scanning sequences included cerebral 3D-T 1WI, T 2WI, diffusion tensor imaging and cervical spinal sagittal 3D-T 2WI, and the cervical spinal cord volume and bilateral diffusion tensor imaging analysis along the perivascular space index (ALPS index) were calculated. The partial correlation test was used to analyze the correlations between ALPS index and the clinical indicators such as EDSS, ARR, and bilateral RNFL, with the control variables as gender, age, years of education and course of disease. The multiple linear regression model was used to analyze the independent predictors for ALPS index and EDSS after treatment. Receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate the diagnostic value of NMOSD treatment outcome by using ALPS index. Results:When controlling for gender, age, years of education and course of disease, there were significant negative correlations between right ALPS index and EDSS ( r=-0.50, P=0.048), bilateral average ALPS index and EDSS ( r=-0.53, P=0.034), left ALPS index and ARR ( r=-0.58, P=0.018), while there was significant positive correlations between right ALPS index and RNFL ( r=0.88, P=0.008) at 1 year follow-up after treatment. Multiple linear regression analysis showed that cervical spinal cord volume was an independent impact factor of bilateral average ALPS indexes (β=0.24, 95%CI 0.10-0.38, P=0.002), and bilateral average ALPS indexes (β=-3.22, 95%CI -5.97--0.48, P=0.024) and right RNFL (β=-0.05, 95%CI -0.08--0.02, P=0.002) at baseline were the independent impact factors of EDSS after treatment. ROC curve analysis showed that the bilateral average ALPS index at baseline had the best efficacy in predicting the curative effect of NMOSD patients with AUC=0.92. Conclusions:After treatment, NMOSD patients with severe clinical disability, high frequency of disease attack, poor visual performance, and severe cervical spinal cord atrophy have more serious impairment of intracerebral glymphatic system circulatory function. The ALPS index could help in predicting the clinical curative effect of NMOSD patients.

Objective: To examine the exposure to television advertising of unhealthy food among children and adolescents in Beijing, in order to provide a basis for the formulation of marketing management policies with unhealthy food. Methods: Four weekdays and four weekend days were randomly selected during October 19, 2020 to January 17, 2021, excluding holidays and school holidays. The top five popular channels of children and adolescents aged 3 to 18 years old were selected. A total of 720 hours was included for coding and analysis. World Health Organization Nutrient Profile Model for the Western Pacific Region was used to classify food and assess the health level. Results: A total of 13 864 advertisings (ads) was monitored, 38.8% (5 376) of which were food ads. Furthermore, 49.9% (2 680) of food ads were unhealthy food ads, with a frequency of 2.00 per hour per channel. The top five most frequent food ads were infant formula for 12-36 months (26.7%), cheese (16.7%), savory snacks (12.2%), milk drinks (10.5%) and chocolate and candy (6.0%). The most frequently used marketing strategies for unhealthy food ads were brand benefit claims (96.8%) and promotional characters (67.9%). Conclusion Children and adolescents in Beijing are highly exposed to TV marketing of unhealthy foods. Marketing strategies such as brand benefit claims and promotional characters are employed to boost the impact of unhealthy food ads. There is an urgent need to introduce relevant policies to regulate TV marketing of unhealthy foods.

Objective:To investigate the effects of long-term high-fat diet on bone mineral density and intestinal flora in mice.Methods:Sixteen male C57BL/6 mice were randomly divided into control group (NC group) and high-fat group (HF group). After 24 weeks of high-fat feeding, biochemical indicators such as blood glucose and blood lipids were detected, bilateral femurs were taken and bone microstructure was analyzed with micro-computered tomography (micro-CT), and changes of intestinal microbial composition and proportion were revealed using 16S rDNA sequencing technology.Results:Compared with the control group, the serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in HF group were significantly increased. Micro-CT uncovered that the bone mineral density (Tb.BMD), bone volume fraction (BV/TV) and the number of trabecular bone (Tb.N) decreased, yet structural model index (SMI) and the trabecular fraction (Tb.Sp) increased in the HF group mice. The gut microbiota 16S rDNA sequence analysis showed that the proportion of Proteobacter was significantly increased and the proportions of pachycete, warty microbacterius, and actinomycete were reduced in HF group at the phyla level. The proportion of Bacteroidetes S24-7_norank in the NC group was significantly higher than that in the HF group, and the multilevel discriminant analysis of species differences (LEfSe) identified that the difference was significant, yet the proportion of Bacteroides, Pseudo-Prevotella, Desulfovibrio, Altobacter, and Helicobacter in the HF group were higher than those in the NC group, which were significant differences in Altobacter and Helicobacter at genus level.Conclusion:Long-term high-fat feeding can cause the destruction of femoral trabecular structure, decrease in the number of trabeculus bones, and bone mineral density in C57BL/6 mice. It also leads to significant changes in the composition and proportion of the intestinal flora.

Objective:To explore the feasibility of using Double FLASH coronary CTA (CCTA) to evaluate myocardial blood perfusion based on the original Patlak Plots.Methods:A total of 50 subjects with non-ischemic heart disease were prospectively included in the study who received dynamic myocardial CT perfusion (CTP) and Double FLASH CTA scans in General Hospital of Tianjin Medical University from January 2018 to January 2020 due to coronary heart disease or suspected coronary heart disease. The age of the enrolled patients was at least 18 years old and there was no moderate or above stenosis on CTA. The dynamic CTP images were analyzed by using CTP analysis software on FRONTIER platform to calculate the CTP derived MBF (MBF CTP). While the CTA derived MBF (MBF CTA) was calculated from the CT attenuation values of both aorta and myocardium segments on two scanning time set of Double FLASH CTA which were measured by two independent radiologists. Pearson correlation and Bland-Altman analysis were used to compare the results of MBF CTP and MBF CTA. Results:There was a strong linear correlation between MBF CTP and MBF CTA measurements. In the mid anteroseptal level: MBF CTA=0.936MBF CTP-11.999, r2=0.600, P<0.01. In the mid anterolateral level: MBF CTA=1.010MBF CTP-9.206, r2=0.448, P<0.01. In the apex: MBF CTA=0.822MBF CTP+16.904, r2=0.375, P<0.01. Bland-Altman analysis also showed there were no significant differences between MBF CTP and MBF CTA measurements. Compared with dynamic CTP scan, Double FLASH CTA mode significantly reduced the radiation dose [(4.33±1.89) mSv vs. (1.38±0.19) mSv, t=4.378, P=0.030]. Conclusions:This study validated the feasibility and accuracy of the MBF CTA measurement based on the theory of Patlak Plots only using Double FLASH CTA images. This method might have the potential to expand the clinical application of one-stop CTP examination for simultaneously evaluating coronary artery and myocardial ischemia in the clinic.

Objective:To evaluate the effect of lifestyle interventions on cardiovascular risk factors in overweight/obese individuals.Methods:A total of 148 overweight/obese subjects who had annual physical exam in the Health Management Center, the First Affiliated Hospital Zhejiang University School of Medicine from Dec 2017 to Dec 2020 were included. They were divided into the self-management group ( n=74) and the intervention group ( n=74). The intervention group was given a 6-month lifestyle intervention, while the self-management group received regular nutrition and physical activity education. Anthropometric and laboratory data was collected at baseline and after intervention in both groups. Effect of the intervention was evaluated. Results:The age of subjects in the intervention and self-management group was (42.5±7.5) and (40.1±9.6) years, respectively. After the intervention, weight, body mass index, waist/hip ratio, visceral fat area, systolic blood pressure, diastolic blood pressure, uric acid, homocystein, triglyceride, alanine aminotransferase andγ-glutamyl transferase of the intervention group [(75.6±12.7) kg, (26.72±3.04) kg/m 2, 0.92±0.05, (104.4±28.5) cm 2, (124.2±13.7) mmHg (1 mmHg=0.133 kPa), (77.8±10.1) mmHg, (353.6±84.8) μmol/L, 9.11(7.73, 10.00) μmol/L, 1.23(0.83, 1.91) mmol/L, 19.5(13.0, 29.5) U/L, 19.0(13.0, 30.5) U/L, respectively] were significantly lower than that of the baseline data [(81.1±12.5) kg, (28.64±2.82) kg/m 2, 0.95±0.04, (127.2±26.6) cm 2, (132.4±14.7) mmHg, (83.2±10.2) mmHg, (387.2±91.2) μmol/L, 10.25(8.30, 11.70) μmol/L, 1.78(1.40, 2.37) mmol/L, 28.0(18.0, 58.0) U/L, 36.0(23.0, 54.3) U/L, respectively] (all P<0.05); compared with the self-management group [(80.1±9.2) kg, 31.7% (28.5%, 38.4%), (119.5±32.6) cm 2, (133.5±15.9) mmHg, (82.6±12.2) mmHg, (4.93±0.86) mmol/L, 1.78(1.26, 2.97) mmol/L, respectively], the intervention group had decreased weight, body fat percent, visceral fat area, systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride [(75.6±12.7) kg, 30.0%(26.3%, 34.3%), (104.4±28.5) cm 2, (124.2±13.7) mmHg, (77.8±10.1) mmHg, (4.53±0.83) mmol/L, 1.23(0.83, 1.91) mmol/L, respectively], and increased high-density lipoprotein cholesterol [(1.09±0.24) vs (1.18±0.28) mmol/L] (all P<0.05). Conclusion:An intensive lifestyle intervention has a beneficial effect on cardiovascular risk factors in overweight/obese individuals.

Objective To investigate the relationship of relative telomere length in cumulus cells(CCs) with oocytes at different mature stages and the outcome of intracytoplasmic sperm injection and embryo transfer (ICSI-ET). Methods Oocyte-cumulus complex samples were collected from 92 patients undergoing ICSI-ET and patients were divided into group A including 55 women≤35 years and group B 37 women>35 years. The embryonic development ability and the result of clinical pregnancy were recorded in different groups. DNA was extracted from CCs and assessed for telomere length by real-time quantitative PCR. Results In ICSI-ET,the relative telomere length of CCs gradually shortened with the age.There was a significantly longer telomere length of CCs in the preg-nant subgroup than that in the non-pregnant subgroup in the two groups(P < 0.05). Conclusion The telomere length of CCs may be associated with the pregnancy outcome in ICSI-ET.

Objective: To investigate the effect of hypertensive disorder complicating pregnancy (HDCP) on the mortality and early complications of premature infants. Methods: The general clinical data of preterm infants with gestational age 24-36^{+ 6} weeks were collected from the cooperative units in the task group from January 1, 2013 to December 31, 2014.According to the severity of HDCP, the infants were divided into 4 groups: HDCP group, preeclampsia group, eclampsia group and non HDCP group, the mortality and major complications of preterm infants were compared, and the influencing factors were analyzed. Results: The mortality rate of preterm in the HDCP group was significantly higher than that of non HDCP group, and there was statistical significance (χ²=9.970, P=0.019). Eclampsia had a highest fatality rate (4.8%) in the early stage, compared with non HDCP group (2.2%), and the difference was statistically significant.Comparison of HDCP group (1.8%) and eclampsia group (3.2%) suggested that there was no statistically significant difference.The incidence of respiratory distress syndrome (RDS) in preterm in HDCP group was significantly higher than that of non HDCP group, and there was statistical significance (χ²=13.241, P=0.004). Eclampsia group showed the highest incidence (35.4%), compared with non HDCP group (16.2%), the difference was statistically significant, but compared with HDCP group (19.9%), preeclampsia group (17.1%), there was no significant diffe-rence.The incidence of bronchopulmonary dysplasia (BPD) in preterm in HDCP group was significantly higher than that of non HDCP group (χ²=9.592, P=0.022), the highest incidence showed up in eclampsia group (9.7%), compared with non HDCP group (2.0%) and HDCP group (1.7%), the difference was statistically significant.But there was no statistically significant difference, compared with preeclampsia group.As the degree of HDCP aggravated, the incidence of BPD gradually rose.There was no significant impact on necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP), intraventricular hemorrhage (IVH) and sepsis of HDCP (χ²=7.054, 7.214, 0.358, 3.852; P=0.070, 0.065, 0.949, 0.278). Considering the overall outcome of the child, that was, whether the child died or survived, he had at least one complication, and HDCP had an effect on it (χ²=15.697, P=0.001), so the incidence increased while the degree of HDCP rose gradually.After adjusting gestational age, birth weight, sex, way of delivery, placental abruption and front placenta, prenatal hormonal, gestational diabetes, neonatal asphyxia and other factors, the results displayed that HDCP was the factor leading to the death of premature baby (OR=2.159, 95%CI: 1.093-4.266), and comparison between preeclampsia and eclampsia showed no statistical difference (P=0.714, 0.389); HDCP had no significant influence on RDS, BDP, ICH, NEC, ROP and sepsis. Conclusions HDCP leads to increased risk of premature death, but also leads to the increased incidence of RDS and BPD, but it had no obvious effect on NEC, ROP, IVH, sepsis and other complications.
