Internet Addiction Among Undergraduate Students: Effect on Eating Behaviours and Sleep Quality

@#Introduction: Internet addiction is one of the major issues among university students which affected not only their academic performance but also their sleep quality and eating behaviours. Thus, this study aims to investigate the association between internet addiction and eating behavior, with sleep quality among undergraduate students at Universiti Sains Malaysia (USM). Method: A cross-sectional study was conducted among 107 university students to obtain data regarding their internet addiction, eating behaviour, and sleep quality through a series of validated questionnaires. The Chi-square test, Mann-Whitney, and Kruskal-Wallis test had been used for the univariate analysis while binary logistic regression was the multivariate analysis. Significance was set as a p-value less than 0.05. Results: A total of 54.2% of the participants showed mild internet addiction and 59.8% of them had poor sleep quality. Severe internet addiction was significantly associated with highest scores in all the eating behaviour. Individuals who were overweight had the highest score for emotional eating. Furthermore, no association was found between internet addiction and eating behavior with sleep quality in both the univariate and multivariate analysis. Conclusion: Internet addiction may affect an individual`s eating behaviour and may potentially lead to several health complications in the future. Those who were overweight tend to be emotional eaters. Although, no significant factors were associated with sleep quality, future research should be done involving other parameters such as physical activity level, biochemical data and comorbidities.

Low diastolic blood pressure and adverse outcomes in inpatients with acute exacerbation of chronic obstructive pulmonary disease: A multicenter cohort study / 中华医学杂志(英文版)

BACKGROUND@#Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients.@*METHODS@#Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes.@*RESULTS@#Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality.@*CONCLUSION@#Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.@*CLINICAL TRIAL REGISTRATION@#Chinese Clinical Trail Registry, No. ChiCTR2100044625.

Incidence and influencing factors of postpartum depression and anxiety among 2 490 puerpera in Urumqi in 2020 / 上海预防医学

ObjectiveTo investigate the incidence and influencing factors of postpartum depression and anxiety in Urumqi during the coronavirus disease （COVID-19） epidemic period in 2020. MethodsResearch subjects were the parturients who underwent postpartum health checkups in a third class hospital in Urumqi from January 2020 to December 2020. The maternal socio demographic and obstetric information were collected， and PHQ-9 and GAD-7 scales were used for screening of PPD and PPA. Calcaneal bone mineral density of the parturients was measured by French Pegasus ultrasonic bone densitometer. After univariate analysis of the related influencing factors of PPD and PPA， multivariate binary logistic regression analysis was used to explore the relationship between mental disorders and various influencing factors. ResultsA total of 2 490 puerpera participated in the survey. The incidences of PPD and PPA in 2020 were 13.4 % and 10.8 %， respectively. Six factors with statistical differences after univariate analysis were included in multivariate binary logistic regression analysis. The final results suggested that age over 35 （OR=1.707，95%CI：1.142‒2.551）， unemployment （OR=1.478，95%CI：1.003‒2.205）， multipara（OR=1.340，95%CI：1.037‒1.733）， bone loss and osteoporosis （OR=1.434，95%CI： 1.076‒1.910） were the risk factors of PPD， while breastfeeding （OR=0.466，95%CI： 0.301‒0.721） was a protective factor. Ages between 18‒24 （OR=1.559，95%CI：1.282‒3.097） and cesarean section （OR=1.433，95%CI： 1.105‒1.859） were the risk factors of PPA， while ages between 30‒34 years old （OR=0.524，95%CI： 0.332‒0.827）， occupation as medical staff （OR=0.282，95%CI： 0.807‒0.919）， breastfeeding （OR=0.530，95%CI： 0.330‒0.850） were protective factors. ConclusionIncidences of PPD and PPA are in middle-low levels during COVID-19 epidemic period. Age， occupation， delivery mode， delivery times， feeding pattern and bone mineral density are the influencing factors. Screen coverage of PPD and PPA in special period should be strengthened， and measures should be taken to reduce the risk.

Periodontitis Patients’ Oral Health Experience and Quality of Life during the Malaysian Movement Control Order-2020 (Pengalaman Kesihatan Pergigian dan Kualiti Hidup Pesakit Periodontitis semasa Perintah Kawalan Pergerakan Malaysia-2020) / Jurnal Sains Kesihatan Malaysia

@#The coronavirus disease 2019 (COVID-19) has sparked concerns among dental patients due to its high infectivity. The implementation of the Movement Control Order in 2020 by the Malaysian government (MMCO-2020) has added constraints to access to dental clinics and may affect the patients’ status of oral disease. This study aims to investigate the impact of MMCO-2020 on the periodontal health and oral health-related quality of life (OHRQoL) of periodontitis patients with/out non-communicable diseases (NCDs). A cross-sectional study involving 139 patients with periodontitis was conducted to assess patients’ OHRQoL, oral health problems, and their perceived barriers to access dental treatment during MMCO-2020 using the Oral Health Impact Profile (OHIP-14) and questionnaire on oral health-related problems. The overall mean OHIP-14 score was relatively low (10.08 ± 8.861), suggesting that the OHRQoL is generally good during MMCO-2020. However, 44 (31.7%) periodontitis patients score ADD ≥14, indicating poorer oral health status and greater dental treatment needed. There was statistically significant association between periodontitis patients with comorbidities (i.e., presence of NCDs) with poorer OHIP-14 scores and mean plaque score changes at pre- and postMMCO, suggesting that special care is required by this group, even during the national lockdown. Of the 45 (32.4%) patients who reported having problems, most (30, 36.1%) decided to “visit the dentist for treatment’. Meanwhile, the most frequent barriers were “could not get an appointment” (14, 34%), “problem is not serious” (13, 39.4%) and “fear of COVID” (9, 27.3%). The MMCO-2020 restrictions on the population had a minimal negative impact on the OHRQoL of patients with periodontal disease, but provisions can be arranged to address the basic and urgent needs of selected periodontitis patients, especially those presented with medical comorbidities.

Research progress in the application of CRISPR/Cas9 technology in the treatment of cervical cancer / 国际生物医学工程杂志

Cervical cancer is the fourth-ranked malignant tumor of female cancer in the world, and it seriously threatens women’s health. The main treatment options for patients with cervical cancer are surgery or concurrent chemoradiotherapy. With the development of medical research, researchers are committed to exploring more effective and specific treatment options in order to increase the treatment options for cervical cancer and improve the treatment effect. Clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein 9 (Cas9) technology is a method in which the Cas9 protein uses guide RNA (gRNA) to target the target gene and achieve precise editing of the target gene. At present, CRISPR/Cas9 technology has become a promising and powerful gene editing tool, a new and effective targeted therapy that has been applied in the treatment of various tumors. The research progress of CRISPR/Cas9 technology in the treatment of cervical cancer is mainly reviewed in terms of action targets, combination therapy strategies, and related drug resistance gene screening in order to provide new strategies for the treatment of cervical cancer.

Effect of aerobic exercise training on EEG: event-related potential and neuropsychological functions in depressed elderly with mild cognitive impairment / Efeito do treinamento de exercício aeróbio no EEG: potencial relacionado a eventos e funções neuropsicológicas em idosos deprimidos com comprometimento cognitivo leve

ABSTRACT. Increased depressive severity has been linked to neurocognitive impairment. Aerobic exercise (AE) is an efficient technique for improving cognitive function. However, studies indicating the importance of AE to neurophysiological and neuropsychological functions in the depressed elderly using event-related potentials (ERPs) are scarce. Objectives: This study aimed to identify the potential benefits of AE on neurophysiological and neuropsychological functions. Methods: A total of 30 depressed older adults (AE group: n=15; control group (CG): n=14) were recruited based on the inclusion and exclusion criteria. The AE group was subjected to an 8-week-period AE program (3 times/week for 30 min per session) at moderate intensity, determined using heart rate maximum (HRmax). The training intensity was set at 50% HRmax and increased by 5% in subsequent weeks. Pre- and post-training measures for neurophysiological function were tested using ERP-P300 (amplitude-μV and latency-ms) and also for neuropsychological functions using the trail making test (TMT), mini mental status examination (MMSE), and everyday cognition questionnaire (ECog). Results: In the experimental group, statistically significant improvements were observed when analyzed for all 3 (group-by-time interaction effect, main effect of time, and main effect of group), in both neurophysiological functions (*p<0.001) and neuropsychological functions (*p<0.001), except for ECog scores, where the results were insignificant for the main effect of a group. Correlation analysis demonstrated no association between neurophysiological and neuropsychological functions (*p>0.05). Conclusion: Findings showed that 8 weeks of AE training may be a promising approach to improve cognitive functions in depressed older adults. However, considering relatively small number of patients, the question arises for effectiveness in other populations.

RESUMO. O aumento da gravidade de quadros de depressão tem sido associado a comprometimento neurocognitivo. O exercício aeróbico (EA) é uma técnica eficiente para melhorar a função cognitiva. No entanto, estudos sugerindo a importância de EA para funções neurofisiológicas e neuropsicológicas usando potenciais relacionados a eventos (PRE) em idosos deprimidos são escassos. Objetivo: Identificar os potenciais benefícios do EA nas funções neurofisiológicas e neuropsicológicas. Métodos: Vinte e nove idosos deprimidos (grupo EA: n=15; grupo controle: GC: n=14) foram recrutados segundo critérios de inclusão e exclusão. O grupo EA foi submetido a um programa de EA de oito semanas (3 vezes/semana em sessões de 30 minutos cada) em intensidade moderada, determinada pela frequência cardíaca máxima (FCmáx). A intensidade do treinamento foi fixada em 50% da FCmax e aumentada em 5% nas semanas subsequentes. As medidas pré- e pós-treinamento para a função neurofisiológica foram testadas pelo ERP-P300 (amplitude-μV e latência-ms) e também para as funções neuropsicológicas usando o Trail Making Test (TMT), o Mini Mental Status Examination (MMSE) e o Everyday Cognition Questionnaire (ECog). Resultados: No grupo experimental, melhorias estatisticamente significativas foram observadas quando analisadas para todos os 3 (efeito de interação grupo por tempo, efeito principal do tempo e efeito principal do grupo), em ambas as funções neurofisiológicas (*p<0,001) e funções neuropsicológicas (*p<0,001), exceto para escores ECog, onde os resultados foram insignificantes para o efeito principal de um grupo. A análise de correlação não demonstrou nenhuma associação entre funções neurofisiológicas e neuropsicológicas (*p>0,05). Conclusão: Os achados mostraram que 8 semanas de treinamento de EA podem ser uma abordagem promissora para melhorar as funções cognitivas em idosos deprimidos. No entanto, considerando um número relativamente pequeno de pacientes, surge a questão da eficácia em outra população.

Progress in microRNA/lncRNA regulating dendritic cell differentiation, maturation and function / 中华微生物学和免疫学杂志

Dendritic cells (DC) as professional antigen-presenting cells can activate na?ve T cells and play an important role in bridging innate immunity and acquired immunity. Therefore, the differentiation and maturation of DC and the mechanism in its function regulatory have attracted much attention. With the rapid development of high-throughput sequencing, noncoding RNAs (ncRNAs) have been gradually known. In recent years, increasing studies have reported that ncRNAs play an importantly role in regulating the differentiation and maturation of DC. In this paper, the regulatory effects of microRNAs and long ncRNAs on the differentiation, maturation and function of DC were reviewed.

Glycyrrhiza uralensis ethanol extract inhibits dendritic cell maturation and ameliorates asthma / 国际生物医学工程杂志

Objective:To investigate the immunoregulatory effects of Glycyrrhiza uralensis ethanol extract(GUEE) on the maturation of dendritic cells (DCs) and the adjuvant effect of GUEE on OVA in na?ve BALB/c mice and an ovalbumin (OVA)-induced asthma mouse model. Methods:GUEE was prepared, and the effects of different concentrations of GUEE on the maturation of DCs and the secreted cytokines as well as the effects of GUEE on bacterial lipopolysaccharide (LPS)-induced DC maturation were examined in vitro. The effect of GUEE on the morphology of mouse bone marrow derived DCs was observed using microscopy. Molecular expression levels on the surface of DCs were detected using flow cytometry. The levels of interleukin-1β (IL-1β), IL-6, IL-12, and tumor necrosis factor-α (TNF-α) in the supernatant of DCs cultures were measured by enzyme-linked immunosorbent assay (ELISA). The maturation status of DCs was detected by flow cytometry by injecting different concentrations of GUEE into the paws of mice and isolating the draining lymph nodes 24 h later. The naive BALB/c mice were co-immunized with OVA, and the changes in regulatory T cells (Treg) were detected by flow cytometry. An OVA-protein-induced mouse asthma model was established to investigate whether GUEE as a tolerogenic adjuvant has an antigen-specific therapeutic effect on asthmatic mice. Pulmonary pathological changes were analyzed by hematoxylin-eosin staining (HE) and PAS staining. OVA-specific antibodies in serum and the frequencies of Tregs, CD4 + IFN-γ + and CD4 + IL-4 + T cells in the spleen were detected by ELISA and flow cytometry, respectively. Results:GUEE suppressed DCs maturation induced by LPS both in vitro and in vivo (all P<0.05), and reduced proinflammatory cytokine production, including IL-1β, IL-6, IL-12 and TNF-α in the absence or presence of LPS (all P<0.05). Moreover, co-immunization with OVA and GUEE increased the amount of Tregs in na?ve BALB/c mice ( P<0.05). In OVA-induced asthmatic mice, OVA and GUEE co-immunization and GUEE alone treatment substantially ameliorated the inflammation of lung tissues, decreased the levels of IgG 1 and the amount of CD4 + IL-4 + T cells, and increased the amount of Tregs (all P<0.05). Conclusions:GUEE alone or as the tolerogenic adjuvant can ameliorate allergic diseases through inhibition of DC maturation and type 2 helper T cell responses and induction of Tregs.

Research progress in antitumor and immunoregulation of fucoidan / 国际生物医学工程杂志

Fucoidan is a kind of sulfated polysaccharide with various biological activities that mainly exists in the cell walls of brown algae. It is also found in marine invertebrates such as sea cucumbers and sea urchins. Fucoidan has received a lot of attention due to its tumor-killing and immune-boosting properties. Moreover, the combination of fucoidan with chemotherapeutic drugs not only improves antitumor efficacy but also reduces the side effects of these drugs. The function of fucoidan is closely correlated with its structure, molecular weight, degree of sulfation, monosaccharide component, algae source, and time of collection. In this review, the antitumor and immunomodulatory effects of fucoidan are reviewed from the aspects of promoting cell apoptosis, inducing cell cycle arrest, inhibiting angiogenesis and cell migration, and activating immune cells, to provide theoretical guidance for the development and clinical application of fucoidan.

Analysis on the glucose and lipid metabolism levels of different sleep duration residents in a community in Urumqi / 中华内分泌代谢杂志

Objective:To investigate different sleep duration and glucose and lipid metabolism levels in residents of a community in Urumqi.Methods:Using the 2 049 residents′ data of chronic metabolic disease in a community of Urumqi collected in May 2017, 1 822 subjects aged between 19-80 years with complete information were enrolled, their blood pressure, waist circumference, height, weight, body mass index were measured and recorded. Using oral glucose tolerance test to measure fasting and 2 h after meal plasma glucose, uric acid, HbA 1C, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C) levels were all tested. Results:(1)There were 363 (19.9%), 1 349 (74.0%), and 110 (6.1%) respondents with sleep time≤6.0, 6.1 to 8.0, and>8.0 h/d, respectively. There were statistically significant differences in age, education, and family income in groups with different sleep time ( P<0.05), while their gender, smoking status, and exercise status were not statistically significant ( P>0.05). The rates of overweight, obesity, abdominal obesity, high uric acid, and hypertension in people with different sleep durations were statistically different ( P<0.01). The rates of the above indicators were higher in the group of sleep time≤6.0 h/d than the other two groups. (2) Differences in diastolic blood pressure, systolic blood pressure, body mass index, abdominal circumference, total cholesterol, and LDL-C levels were statistically significant among different sleep duration groups ( P<0.05). Further comparisons of the above indicators among three groups with different sleep durations were performed ( P<0.05). The levels of the above indicators in the sleep time≤6.0 h/d group were higher than those in the other two groups. There were no significant differences in fasting blood glucose, glycated hemoglobin, uric acid, triglyceride, and HDL-C among the three groups. (3) Multivariate logistic regression analysis showed that groups whether or not adjusted of age, family income, and education level, sleep time≤6.0 h/d was related to abdominal obesity, and sleep time≤6.0 h/d was be a risk factor for abdominal obesity [Unadjusted: OR=1.48(95% CI1.04-2.08); Adjusted: OR=1.65(95% CI1.18-2.32; P<0.05]. Conclusion:Sleep time ≤6.0 h/d is associated with abdominal obesity, and sleep time≤6.0 h/d may be a risk factor for abdominal obesity.

Mechanism of ferroptosis and its role in liver diseases / 临床肝胆病杂志

Ferroptosis is a newly discovered regulatory cell death induced by the accumulation of iron-dependent lipid peroxides, with the morphological manifestations of decreased mitochondrial volume, increased mitochondrial membrane density, and reduction or disappearance of mitochondria. The mechanism of ferroptosis is mainly associated with disturbance of iron metabolism, imbalance of amino acid antioxidant system, and accumulation of lipid peroxides. Studies have shown that ferroptosis plays different roles in different liver diseases, and ferroptosis can participate in the progression of various liver inflammatory diseases and inhibit the formation of liver fibrosis, the development of hepatocellular carcinoma, and sorafenib resistance. This article summarizes the advances in the mechanism of ferroptosis and its role in liver diseases, so as to provide a reference for further research and treatment of liver diseases.

Distribution of virulence genes and the molecular epidemiology of Streptococcus pyogenes clinical isolates by emm and multilocus sequence typing methods

@#Background: Streptococcus pyogenes has a variety of virulence factors and the predominant invasive strains differ according to specific emm types and geographical orientation. Although emm typing is commonly used as the gold standard method for the molecular characterisation, multilocus sequence typing (MLST) has become an important tool for comparing the genetic profiles globally. This study aimed to screen selected virulence genes from invasive and non-invasive clinical samples and to characterise the molecular epidemiology by emm typing and MLST methods. Materials and Methods: A total of 42 S. pyogenes isolates from invasive and non-invasive samples collected from two different tertiary hospitals were investigated for the distribution of virulence factors and their molecular epidemiology by emm and multilocus sequence typing methods. Detection of five virulence genes (speA, speB, speJ, ssa and sdaB) was performed using multiplex polymerase chain reaction (PCR) using the standard primers and established protocol. Phylogenetic tree branches were constructed from sequence analysis utilised by neighbour joining method generated from seven housekeeping genes using MEGA X software. Results: Multiplex PCR analysis revealed that sdaB/speF (78.6%) and speB (61.9%) were the predominant virulence genes. Regardless of the type of invasiveness, diverse distribution of emm types/subtypes was noted which comprised of 27 different emm types/subtypes. The predominant emm types/subtypes were emm63 and emm18 with each gene accounted for 11.8% whereas 12% for each gene was noted for emm28, emm97.4 and emm91. The MLST revealed that the main sequence type (ST) in invasive samples was ST402 (17.7%) while ST473 and ST318 (12% for each ST) were the major types in non-invasive samples. Out of 18 virulotypes, Virulotype A (five genes, 55.6%) and Virulotype B (two genes, 27.8%) were the major virulotypes found in this study. Phylogenetic analysis indicated the presence of seven different clusters of S. pyogenes. Interestingly, Cluster VI showed that selected emm/ST types such as emm71/ST318 (n=2), emm70.1/ST318 (n=1), emm44/ST31 (n=1) and emm18/ST442 (n=1) have clustered within a common group (Virulotype A) for both hospitals studied. Conclusion: The present study showed that group A streptococcci (GAS) are genetically diverse and possess virulence genes regardless of their invasiveness. Majority of the GAS exhibited no restricted pattern of virulotypes except for a few distinct clusters. Therefore, it can be concluded that virulotyping is partially useful for characterising a heterogeneous population of GAS in hospitals.

Dietary nutritional status of AIDS orphans / 中国学校卫生

Objective@#To understand the dietary nutritional status of AIDS orphans aged 7-12 in Urumqi, and to provide a scientific basis for promoting growth, development and health.@*Methods@#Using a random sampling method, a total of 309 children aged 7-12, from Urumqi were selected. The sample included 98 orphans with AIDS, 66 orphaned children not affected by AIDS, and 145 cases of non orphaned children. A 24 hour diet review method was used to record the diet of all three groups of children who received three meals per day, energy levels and the nutrient intake of AIDS orphans and their attainment were analyzed according to the daily recommended nutrient intake (RNI) of Chinese residents.@*Results@#The detection rate of wasting in the AIDS orphans group was 44.9%, which was higher than that in the orphans without AIDS group (40.9%) and the non orphaned group ( 28.2 %); the overweight rates of AIDS orphans and orphans without AIDS were 3.1% and 3.0%, respectively, which were both lower than those of non orphaned children (8.3%); the average daily intake of energy and dietary nutrients in the AIDS orphans group was lower than that in the other two groups, and the intake of vitamin A, vitamin B 2, vitamin B 6, vitamin C,vitamin D, folic acid, calcium, zinc, and iron was seriously insufficient, the intake of food grains, vegetables, fruit, eggs, milk and dairy products, and the average daily intake of oil was lower among AIDS orphans than orphans without AIDS and non orphaned children, additionally,except for food grains,eggs, there were significant differences between the three groups ( F =3.02，5.23，27.86，16.59， P <0.05), and the daily intake of vegetables, aquatic products, eggs and milk in AIDS orphans and orphans was lower than the recommeded intake.@*Conclusion@#A higher rate of wasting, unbalanced nutrient intake, and poor nutritional status was found among AIDS orphans aged 7-12 in Urumqi. Therefore, there is a need to improve the dietary structure of AIDS orphans with the aim of promoting healthy development.
