ABSTRACT

Objective@#To identify the lifestyle pattern of adolescents in Guangzhou and to provide a scientific basis for targeted and individualized interventions for adolescents with different lifestyle pattern.@*Methods@#A survey was conducted by questionnaire among 12 540 students from 27 middle schools in the urban area of Guangzhou using a convenient sampling method. The latent class model (LCM) was used to identify lifestyle patterns of adolescents, and further analyses were conducted to compare differences in dietary habits and willingness to exercise among the different classes.@*Results@#Three lifestyle patterns were identified based on the latent class model: "high sweet snacks/excessive screen time, sleep and exercise deficiency group", 3 797 people, accounting for 30.3%; "low nutrition diet/severe sleep and exercise deficiency group", 2 745 people, accounting for 21.9%; "general diet/sleep and exercise deficiency group", 5 998 people, accounting for 47.8%. Adolescents of different classes had different perceptions of their eating habits and different degrees of willingness to participate in physical exercise, these differences were statistically significant(χ 2=671.54, Z=153.16, P<0.05).@*Conclusion@#The results of the latent class model showed that the three classes of adolescents had their own unique characteristics. It is necessary to inform them of their needs, provide guidance and implement targeted interventions according to the unique characteristics of the different lifestyle patterns in empirical work.

ABSTRACT

Objective@#To explore the influence of birthweight and delivery mode on overweight/obesity and abdominal obesity in primary school students, and to provide evidence for childhood obesity prevention.@*Methods@#After physical examination, questionnaire survey was conducted among 3 361 students and their parents from 3 primary schools in Guangzhou selected through stratified clustering sampling. Information about birthweight and delivery mode was collected. Logistic regression model was used to analyze the association of birthweight and delivery mode with overweight/obesity and abdominal obesity. The multiplicative interaction term and the Delta method was used to explore the potential interaction.@*Results@#The prevalence rate of overweight and obesity for primary school students was 21.33%, and the rate of abdominal obesity was 12.08%. Multivariate Logistic regression analysis showed that delivery by cesarean section was associated with 44% increased risk of overweight/obesity(OR=1.44, 95%CI=1.16-1.80), as compared to vaginal delivery. Higher birthweight was linked to increased risk of overweight/obesity(OR=1.62, 95%CI=1.09-2.42). There was no significant association of birth weight and delivery mode with abdominal obesity in multivariate analysis(P>0.05). Additionally, a positive additive interaction was seen between delivery mode and parental obesity for students risk of overweight/obesity(RERI=0.33, 95%CI=0.02-0.65), as well as for the risk of abdominal obesity(RERI=0.39, 95%CI=0.12-0.65).@*Conclusion@#Cesarean section delivery and higher birthweight are linked to increased risk of overweight and obesity in primary school students. The synergistic effect of cesarean section and parental obesity may increase the risk of childhood obesity.

ABSTRACT

Abstract@#MiRNAs are a type of single-stranded, endogenous, non-coding small RNAs, which can regulate the post-transcriptional expression of genes and a variety of biological functions. Puberty development involves a complex regulatory network, among which the the hypothalamic-pituitary-gonad axis may play the key role. Studies have found that there was a relationship between the miRNAs and puberty development. The absence and abnormal expression of miRNAs can affect the initiation of puberty. But the mechanism is not clear. It may be related to the secretion of GnRH in the hypothalamus. This article mainly introduced several miRNAs which were currently closely related to the initiation of puberty, and reviewed their role and possible mechanisms in the initiation of puberty.

ABSTRACT

Head and neck squamous cell carcinoma (HNSCC) is one of the most common malignant tumors. Ethanol extract of Antrodia cinnamomea (EEA) has been widely studied for its health benefits including anticancer effects. The purpose of this study was to assess the effects of EEA on HNSCC. Cell proliferation, transwell, and wound healing assays were performed. The impact of EEA on tumor growth was investigated using a xenograft model. Expressions of migration-related proteins (MMP-2, MMP-9, TIMP-1, and TIMP-2) and apoptosis-related proteins (cleaved caspase-9 and cleaved PARP) were determined using western blot analysis. The results indicated that EEA significantly inhibited the capacities of proliferation, invasion, and migration of HNSCC cells in a dose-dependent manner. Cleaved caspase-9 and cleaved PARP expressions were increased in cells treated with an increasing concentration of EEA, which suggested that EEA induced apoptosis of HNSCC. MMP-2 and MMP-9 were downregulated when cells were administered EEA, while TIMP-1 and TIMP-2 were not affected, which uncovered the mechanisms mediating the EEA-induced inhibition on cell invasion and migration. The animal experiment also suggested that EEA inhibited tumor growth. Our study confirmed the inhibitive effects of EEA on cell proliferation, invasion, and migration of HNSCC in vitro and in vivo, providing the basis for further study of the application of EEA as an effective candidate for cancer treatment.

ABSTRACT

This study aimed to investigate whether the routine administration of escitalopram for three months would improve the prognosis of patients with ischemic stroke and decrease the plasma copeptin level. A total of 97 patients with acute cerebral infarction were randomly allocated to receive escitalopram (5-10 mg once per day, orally; n=49) or not to receive escitalopram (control group; n=48) for 12 weeks starting at 2-7 days after the onset of stroke. Both groups received conventional treatments, including physiotherapy and secondary prevention of stroke. The National Institutes of Health Stroke Scale (NIHSS) score was used to evaluate the disability of patients at the initial evaluation and at the monthly follow-up visits for three months. Impairment in the daily activities was assessed using the Barthel Index (BI), while cognitive impairment was assessed using Mini-Mental State Examination (MMSE) score. The psychiatric assessment included the administration of the Present State Examination modified to identify Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) symptoms of depression. The severity of depression was measured using the 17-item Hamilton Rating Scale for Depression (HAMD). During the 3-month follow-up period, 95 patients were included in the analysis (two patients withdrew from the escitalopram group). NIHSS and BI improvement at the 90th day were significantly greater in the escitalopram group (P<0.05), while HAMD and plasma copeptin levels significantly decreased, compared to the control group (P<0.01). In patients with acute ischemic stroke, the earlier administration of escitalopram for three months may improve neurological functional prognosis and decrease copeptin level.

ABSTRACT

OBJECTIVES: This study intended to explore the effect of T regulatory cells (Tregs) in the perinatal liver against LPS-induced inflammation in a preterm birth mouse model. Moreover, the role of adoptive Tregs on the inflammatory response induced by LPS was also studied. METHODS: Female BALB/C mice were injected intraperitoneally (IP) with LPS dissolved in normal saline solution at a dose of 50 µg/kg. Spleens from pregnant mice were used to obtain Tregs. The expression of Forkhead family transcription factor-3 (Foxp3), Interleukin-6 (IL-6), Toll-like receptor-4 (TLR-4), and Heme oxygenase-1 (HO-1) were assessed from fetal liver tissues by polymerase chain reaction and western blotting. RESULTS: LPS administered to mice induced an inflammatory response in the perinatal liver, and this inflammatory response was negatively regulated by Tregs in the experimental group. Maternal-fetal tolerance was maintained by Tregs. Transmission of Tregs was estimated in different experimental groups based on the mRNA expression of TLR-4, IL-6, HO-1, and Foxp3. CONCLUSIONS: After analysis of the experimental data, it was determined that Tregs exhibited regulatory potential against LPS-induced inflammatory response. Further, it was concluded that the transmission of Tregs improved the mother's immune tolerance against LPS-induced inflammation in the fetal liver.

ABSTRACT

Objective@#To provide baseline data for the development of physical activity and health promotion strategies and public health policy among Chinese children and adolescents by systematically evaluating accelerometermeasured moderatetovigorous physical activity (MVPA) and sedentary behavior(SB).@*Methods@#The study search was carried out using China National Knowledge Infrastructure, SPORTDiscus with Full Text, and Web of Science, including studies that published from January 1, 2009 to February 28, 2019. The studies were selected by inclusion (based on PICOS principles) and exclusion criteria, and were assessed through quality assessment items based on revised STROBE statement. The information about MVPA and SB were extracted, and Comprehensive Metaanalysis Software (CMA V2) was used to pool the findings from the included studies into a Metaanalysis.@*Results@#Sixteen studies published from 2012 to 2019 were included the Metaanalysis. Sample sizes of eligible studies ranged from 96 to 2 163 participants. Metaanalysis found that Chinese children and adolescents separately spent 37.66 min/day, 539.61 min/d in MVPA and SB. Boys were more likely to have higher level of MVPA in minutes compared to the girls’(P<0.01). Children and adolescents spent more time in MVPA on weekdays than weekends(P<0.05), and also spent more SB on weekdays than weekends(P<0.05).@*Conclusion@#Chinese children and adolescents are physically inactive and live a sedentary lifestyle in general, especially among girls. MVPA and SB time among children and adolescents spent on weekdays are higher than weekends.

ABSTRACT

Objective@#Exploring the effects of susceptibility genes on aggressive periodontitis during its occurrence and development lays a foundation for further research on its genetic pathogenesis.@*Methods@#Medical history and clini⁃ cal indicators were collected from monozygotic twins with generalized aggressive periodontitis. Susceptibility genes were detected by polymerase chain reaction⁃restriction fragment length polymorphisms, and the exon gene components were analyzed by whole⁃exome sequencing. @*Results @#The severity of generalized aggressive periodontitis in the twins was dif⁃ ferent (P < 0.05). Florida diagnosis results showed that the younger sister’ s explored clinical depth (probing depth, PD) and clinical attachment loss (CAL) were higher than those for the elder sister, but her clinical bleeding index (bleeding on probing, BOP) was lower than that of the elder sister. In addition, their responses to periodontal basic treatment were different (P < 0.05). After treatment, the improvement of CAL and decline in BOP were more obvious in the elder sister,and the proportion of different periodontal pocket depths in the elder sister decreased after treatment, while the de⁃ crease was slighter in the younger sister. Genetic tests revealed that the twins had the same genotypes at target suscepti⁃ bility genes (IL⁃1β⁃511, IL⁃1β+3953, TNF⁃α⁃308, FcγR⁃IIIb, VDR, and ER) and differential exon gene components, and that the suspected differential genes, e.g. ZFPM1, PTH2, ZFYVE16, and LY6G6C, might be related to their pheno⁃ typic differences.@* Conclusion@#These monozygotic twins had different phenotypes of generalized aggressive periodonti⁃ tis. Their shared susceptibility genes increased the risk of disease, and their different genetic mutations affected the phe⁃ notype of the disease

ABSTRACT

OBJECTIVE@#To analyze the overall survival (OS) of elderly acute myeloid leukemia (AML) patients treated with oral arsenic-containing Qinghuang Powder (, QHP) or low-intensity chemotherapy (LIC).@*METHODS@#Forty-two elderly AML patients treated with intravenous or subcutaneous LIC (1 month for each course, at least 3 courses) or oral QHP (3 months for each course, at least 2 courses) were retrospectively analyzed from January 2015 to December 2017. The main endpoints of analysis were OS and 1-, 2-, 3-year OS rates of patients, respectively. And the adverse reactions induding bone marrow suppression, digestive tract discomfort and myocardia injury were observed.@*RESULTS@#Out of 42 elderly AML patients, 22 received LIC treatment and 20 received QHP treatment, according to patients' preference. There was no significant difference on OS between LIC and QHP patients (13.0 months vs. 13.5 months, >0.05). There was no significant difference on OS rates between LIC and QHP groups at 1 year (59.1% vs. 70.0%), 2 years (13.6% vs. 15%), and 3 years (4.6% vs. 5.0%, all >0.05). Furthermore, there was no significant difference of OS on prognosis stratification of performance status > 2 (12 months vs. 12 months), age> 75 year-old (12.0 months vs. 12.5 months), hematopoietic stem cell transplant comorbidity index >2 (12 months vs. 13 months), poor cytogenetics (12 months vs. 8 months), and diagnosis of secondary AML (10 months vs. 14 months) between LIC and QHP patients (>0.05).@*CONCLUSION@#QHP may be an alternative treatment for elderly AML patients refusing LIC therapy.

ABSTRACT

Objective@#To understand the AIDS knowledge of male college students who have sex experience and the influencing factors of high-risk sexual behaviors, so as to provide a basis for AIDS prevention and control on campus.@*Methods@#A total of 5 718 male college students who have sex from 18 colleges and universities in Nanjing were investigated by stratified random cluster sampling method from April to June in 2019. Their AIDS knowledge and high-risk sexual behaviors were investigated and risk factors were analyzed.@*Results@#Male college students had poor AIDS related knowledge and the incidence of high-risk sexual behaviors was 61.5%. Logistic regression analysis showed that the proportion of male college students with sexual orientation of bisexuality(OR=1.61), uncertainty (OR=2.41) and heterosexuality (OR=1.47) who had high-risk sexual behaviors were higher than those of homosexuals. The age of first sexual intercourse ≤14 years old(OR=2.71), 15 to 17 years old(OR=1.87), and 18 to 20 years old (OR=1.35) had a higher proportion of high-risk sexual intercourse than the age of first sexual intercourse of older than 20 years old. In the past year, the proportion of commercial sex(OR=1.80), drug use(OR=4.28), sexually transmitted disease (OR=3.34) diagnosed in the most recent year who had high-risk sexual behaviors were higher. In the pust year, the proportion of stable relationship and cohabitation(OR=0.25), those who had received AIDS prevention propaganda in the most recent year(OR=0.81), and those who knew about AIDS (OR=0.65) were less likely to engage in high-risk sexual behaviors.@*Conclusion@#The knowledge rate of HIV/AIDS was low and the incidence of high-risk sexual behavior was high among male college students. Therefore, colleges are encouraged to, actively carry out AIDS prevention and control work, improve the awareness of both HIV/AIDS knowledge and safe sex basics.

ABSTRACT

Objective@#To investigate the effect of maternal passive smoking during pregnancy and girls’ overweight /obesity on the age at menarche(AAM), and to provide a reference for improving healthy development of children and adolescents.@*Methods@#Based on the school entrance physical examination in 2016, a cross-section study was conducted by convenient sampling method, in a total of 2 722 students of 7th grade, from 26 middle schools in urban areas of Guangzhou. Multivariate logistic regression model was used to investigate the relationship between maternal passive smoking during pregnancy and girls’ overweight /obesity and AAM. A four-way decomposition method was used to explore the mediated effect of girls’ overweight/obesity on the relationship between maternal passive smoking during pregnancy and AAM.@*Results@#The proportion of girls who had menstruate was 90.82%(2 472/2 722). The median AAM was 12.00 years old, with an early menarche rate of 34.91%(863/2 472). Compared with girls whose mother hadn’t passive smoking during pregnancy, the risk of early AAM in girls with mother passive smoking during pregnancy≤3 days/week increased by 32%(OR=1.32, 95%CI=1.06-1.65), the risk in girls with maternal passive smoking during pregnancy>3 days/week increased by 58%(OR=1.58, 95%CI=1.21-2.07). Multivariate Logistic regression analysis showed that, overweight or obesity girls had a 77% higher risk of early AAM than non-overweight/obesity girls(OR=1.77, 95%CI=1.36-2.31). The four-way decomposition analysis showed 79.60% of early AAM risk could be accounted by maternal passive smoking during pregnancy(P<0.01).@*Conclusion@#Girls’ overweight/obesity and maternal passive smoking during pregnancy were associated with early menarche. The effect on daughters’ age at menarche is mainly in a direct effect manner of maternal passive smoking during pregnancy.

ABSTRACT

@#To investigate the current status of milk and dairy product intake of primary and middle school students in Guangzhou and to explore the influencing factors, to provide the basis for promoting the consumption of milk and dairy products for students.@*Methods@#Questionnaire survey was conducted among 7 948 students selected from 3 primary schools and 3 middle schools in Guangzhou. The contents included general information, average amount of the intake of milk and dairy products (including pure milk, yoghurt, milk powder, cheese and other dairy products). Using χ2 test and multivariate Logistic regression to analyze the influencing factors of students’ milk and dairy product intake.@*Results@#About 76.12% of all participants reported milk and dairy products intake<7 times/week, 78.88% reported milk and dairy products intake<300 g/d and the median of milk and dairy products was 178.57 g/d. In the multiple Logistic regression model, girls and high school students were more likely to consume milk and dairy products insufficiently, with the OR of 1.42 (95%CI=1.26-1.60), 1.86 (95%CI=1.51-2.28) respectively. The students with father’s education level being college degree or above (OR= 0.75, 95%CI=0.59-0.94), mother’s education level being high school or above (high school:OR=0.75, 95%CI=0.61-0.93, college degree or above:OR=0.58, 95%CI=0.46-0.72) and annual household income ≥200 000 (OR=0.77,95%CI=0.64-0.92) were more likely to consume sufficient milk and dairy products.@*Conclusion@#Consumption of milk and dairy products among primary and middle school students in Guangzhou was high but not meet the recommended amount,should be strengthened. Health and nutritional education for students and their parents,especially girls and senior students,should be strengthened to promote the milk and dairy products consumption.

The physical indicators and daily routine were collected by physical examination and questionnaire survey. Multiple Logistic regression analysis was used to explore the association between screen time and dietary behaviors among students.@*Results@#The proportion of excessive screen time was 18.80% (2 323). There was no significant difference between boys (18.52%, 1 165/6 292) and girls (19.09%, 1 158/6 065) (χ2=0.67, P>0.05). Logistic regression results showed that excessive screen time was negatively associated with consumption of vegetables and fruits, with the aORs of 0.50 (95%CI=0.42-0.58) and 0.64 (95%CI=0.58-0.70) respectively, and positively associated with consumption of fried food (OR=1.90, 95%CI=1.70-2.09), western fast food (OR=1.90, 95%CI=1.65-2.19), sweets (OR=1.36, 95%CI=1.25-1.49) and sugar-sweetened beverage (OR=1.70, 95%CI=1.57-1.84).@*Conclusion@#Excessive screen time was associated with unhealthy dietary behaviors among middle school students in Guangzhou. Intervention should be tailored to screen time as well as dietary behaviors.

ABSTRACT

Objective@#To investigate the clinical effects of Qinghuang powder, low-intensity chemotherapy and Qinghuang powder alternated with low-intensity chemotherapy in the treatment of elderly acute myeloid leukemia patients progressed from myelodysplastic syndromes (MDS-AML).@*Methods@#A total of 32 elderly patients with MDS-AML treated in Xiyuan Hospital, China Academy of Chinese Medical Sciences from January 2014 to December 2017 were retrospectively analyzed. Of them, 12 patients received Qinghuang powder (Qinghuang powder group), 6 patients received Qinghuang powder alternated with low-intensity chemotherapy (alternating group), and 14 patients received low-intensity chemotherapy (low-intensity chemotherapy group), based on the real world of patient's voluntary choice of treatment. The efficacy and adverse reactions in the 3 groups were observed.@*Results@#The overall response number of Qinghuang powder, alternating, and low-intensity chemotherapy groups were 2, 2 and 4 cases, respectively, there was no significant difference among the 3 groups (P > 0.05). The median overall survival time of 3 groups were 14, 12 and 8 months, respectively, there was no significant difference among the 3 groups (P > 0.05). Two cases in Qinghuang powder group presented with gastrointestinal reactions; 3 cases in alternating group with myelosuppression, 2 cases with liver function damage, and 2 cases with gastrointestinal reaction; 11 cases in low-intensity chemotherapy group presented with bone marrow suppression, 3 cases with liver function damage, 7 cases with gastrointestinal reactions, and 2 cases with myocardial enzyme changes. The incidences of myelosuppression, liver function damage and myocardial enzyme changes in Qinghuang powder group were lower than those in the alternating group and low-intensity chemotherapy group.@*Conclusion@#The efficacy of Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy for the treatment of elderly MDS-AML is not worse than the low-intensity chemotherapy, furthermore Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy has fewer adverse reactions and better tolerance.

ABSTRACT

Objective: A Logistic model for quality evaluation of Persicae Semen slices was constructed and its feasibility was verified in this study based on the thoughts on quality control of Chinese materia medica “Components reflect activity and activity points to efficacy”. Methods: Content of amygdalin, thrombin time (TT), ABTS clearance rate, DPPH inhibition rate, and hydroxyl radical scavenging ability in vitro were analyzed by a binary Logistic algorithm. Besides, a grade prediction model for Persicae Semen was established and verified. Results: A total of 18 batches of Persicae Semen were divided into four grades: excellent (represented by Neimeng Persicae Semen), good (represented by Gansu Persicae Semen), medium (represented by Liang Persicae Semen), and poor (represented by Shaanxi Persicae Semen) according to the probability formula of the Logisitc model. All batches of Persicae Semen slices were classified accurately, manifested by the high value of fitting probability (P > 98%). Conclusion: The classification standard based on the Logistic algorithm involving quality control component-in vitro titer is applicable to Persicae Semen slices on the market. Classification results are accurate and reliable.
