ABSTRACT

Objective@#The aim of this study was to establish a comprehensive concise health index (CHI) for evaluating adolescents, so as to provide a basis for determining the overall health status of adolescents in China.@*Methods@#On the basis of a literature review and consensus among core researchers, adolescent CHI indicators in the following five dimensions were assessed:physical growth, physical fitness, common diseases, mental health and behavioral health. A total of 24 experts used an analysis hierarcgy process (AHP) to calculate the indicators subjective weights. In addition, from October to December of 2021, two regions, A and B were selected to conduct empirical research, and the CRITIC method was used to calculate the objective weights of the indicators. Finally, the weight coefficients were determined through the AHP-CRITIC combination weight method, and comprehensive evaluation was performed with the TOPSIS method.@*Results@#Across academic period and genders, the combined weighted coefficients of the health indicators were as follows:BMI, 0.081-0.095; waist circumference, 0.070-0.081; relative grip strength, 0.101-0.108; myopia, 0.110-0.128; dental caries, 0.055-0.070; psychological symptoms, 0.240-0.262; physical exercise, 0.085-0.115; screen time, 0.097-0.111; and sleep duration, 0.086-0.103. The health index of middle school students in city A (0.626±0.065) was significantly higher than that in city B(0.613±0.066)( t=6.34, P <0.01).@*Conclusion@#The comprehensive adolescent CHI evaluation method has good consistency and application value, and may serve as a reference for adolescent health monitoring.

ABSTRACT

Objective@#To determine the association between anthropometric parameters and 20 meter shuttle run test (20 m SRT) score among children and adolescents.@*Methods@#The convenient sampling method was conducted to select 3 192 primary and secondary school students in Baoan District, Shenzhen, based on the street school types school from April to May 2019. Height, weight, 20 m SRT score and general demographic indicators were assessed and collected. Individuals were divided into two groups based on the dose response correlation between different anthropometric parameters (the Z score of height, weight and BMI) and 20 m SRT score analyzed with the restricted cubic spline. The association between the Z score of height and 20 m SRT score was further analyzed using the Spearman correlation analysis. Logistic regression analysis was used to analyze separately the relationship different anthropometric parameters and 20 m SRT score.@*Results@#The Z value of weight and 20 m SRT score showed a non linear dose response association ( P <0.01), the significant but weak linear correlation between the Z value of height and 20 m SRT score ( r=0.06, P <0.05). The prevalence rate on the low level of the Z value of 20 m SRT score in 3 192 children and adolescents was 44.7%, and the gender ( χ 2=14.02, P <0.01) and grade difference ( χ 2=93.28, P <0.01) were both statistically significant. There was no significant relationship between the Z value of height and 20 m SRT score grade among total population, different genders and different grades ( P > 0.05). Compared with the reference group on the Z value of weight ≤-0.23, individuals with the Z value of weight >-0.23 had the low level of 20 m SRT score ( OR =0.61, P <0.05). Compared with the reference group on the Z value of BMI ≤ 0.25, individuals with the Z value of weight >0.25 had the low level of 20 m SRT score ( OR =0.45, P <0.05). Stratified for gender and grade, the above significant relationship on the Z value of weight, Z value of BMI and 20 m SRT score were still observed ( P <0.01).@*Conclusions@#The higher height Z value shows on correlations with 20 m SRT score, but the positive association is found between weight and BMI Z value and the 20 m SRT score. The cardiopulmonary fitness improvement may be more effective among children and adolescents when tuking weight and BMI Z scores into consideration.

ABSTRACT

Abstract Objectives Tripartite Motif 47 (TRIM47) protein plays a prominent role in many cancers. This study aimed to investigate the biological roles of TRIM47 in ovarian cancer. Methods TRIM47 was knocked down and overexpressed in ovarian cancer cell lines SKOV3 and OVCAR3, and the effects on proliferation, clone formation, apoptosis, invasion, and growth of xenograft tumors in nude mice were determined. The expression levels of the selected candidates were tested by western blotting and quantitative real-time PCR. Results TRIM47 knockdown suppressed proliferation and encourages apoptosis of ovarian cancer cells. Similarly, TRIM47 knockdown suppressed ovarian cancer cell invasion, migration, and epithelial-mesenchymal transition. Ovarian cancer cell xenograft assays demonstrated that TRIM47 knockdown significantly inhibited tumor growth. Mechanistically, TRIM47 knockdown suppressed STAT3 phosphorylation and the expression of several downstream genes, including MCL-1, MMP2, and c-MYC. Silencing of STAT3 partially prevented TRIM47-induced tumor cell proliferation and invasion. Conclusion The present study's findings demonstrate that by activating STAT3 signaling, TRIM47 functions as an oncogene in ovarian cancer. TRIM47, therefore, appears to be a potential target for ovarian cancer prevention and/or therapy.

ABSTRACT

Snakebites remain a major life-threatening event worldwide. It is still difficult to make a positive identification of snake species by clinicians in both Western medicine and Chinese medicine. The main reason for this is a shortage of diagnostic biomarkers and lack of knowledge about pathways of venom-induced toxicity. In traditional Chinese medicine, snakebites are considered to be treated with wind, fire, and wind-fire toxin, but additional studies are required. Methods: Cases of snakebite seen at the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine were grouped as follows: fire toxin - including four cases of bites by Agkistrodon acutus and three bites by Trimeresurus stejnegeri - and wind-fire toxin - four cases of bites by vipers and three bites by cobras. Serum protein quantification was performed using LC-MS/MS. Differential abundance proteins (DAPs) were identified from comparison of snakebites of each snake species and healthy controls. The protein interaction network was constructed using STITCH database. Results: Principal component analysis and hierarchical clustering of 474 unique proteins exhibited protein expression profiles of wind-fire toxins that are distinct from that of fire toxins. Ninety-three DAPs were identified in each snakebite subgroup as compared with healthy control, of which 38 proteins were found to have significantly different expression levels and 55 proteins displayed no expression in one subgroup, by subgroup comparison. GO analysis revealed that the DAPs participated in bicarbonate/oxygen transport and hydrogen peroxide catabolic process, and affected carbon-oxygen lyase activity and heme binding. Thirty DAPs directly or indirectly acted on hydrogen peroxide in the interaction network of proteins and drug compounds. The network was clustered into four groups: lipid metabolism and transport; IGF-mediated growth; oxygen transport; and innate immunity. Conclusions: Our results show that the pathways of snake venom-induced toxicity may form a protein network of antioxidant defense by regulating oxidative stress through interaction with hydrogen peroxide.(AU)

ABSTRACT

@#Eye tracker is an instrument that can record the characteristics of eye movement when people process visual information. This instrument is important for basic psychological research. In the study of dental aesthetics, an eye tracker reflects the observer′s objective eye movement pattern and reveals the underlying aesthetic psychology. This paper summarizes the major research methods of dental aesthetics while focusing on eye-tracking studies in oral aesthetics. Eye tracking studies show that different population has different eye movement patterns when observing the same faces, while the same population can have different eye movement patterns when observing the faces of dental patients and normal people. This finding reveals that the personal characteristics and experience, the social environment and the featured facial structure of the observed individuals can influence eye movement patterns. This study also shows the factors that cause the aesthetic differences among different individuals and groups, as well as the psychological mechanisms.

ABSTRACT

@#Objective:To investigate the role of cyclo-oxygenase-2 (COX-2) in breast cancer metastasis and its possible mechanism. Methods: A total of 45 cases of primary breast cancer tissues and brain metastatic breast cancer tissues were collected from patients, who underwent mastectomy in Yunnan Cancer Hospital from October 2015 to April 2018, including 30 cases of primary lesions and 15 cases of brain metastasis. qPCR was used to detect the expression of COX-2 in breast cancer tissues and brain metastatic breast cancer tissues. Recombinant viruses with COX-2 over-expression (LV6-COX2) or COX-2 knockdown (LV3-COX2 shRNA1, LV3-COX2 shRNA2) were transfected into human breast cancer MDA-MB-231 cells; After obtaining the stable expression cell lines, the effect of COX-2 expression on the proliferation of MDA-MB-231 cells was detected by CCK-8, and the effects of COX-2 expression on the migration and invasion of MDA-MB-231 cells were detected by scratch test and Transwell assay, respectively. The mRNAand protein expressions of COX-2 in each group were examined by qPCR and WB, respectively. The effect of COX-2 expression on the expression of EMT-related genes in MDA-MB-231 cells was analyzed by qPCR. Results: The expression of COX-2 in tissues of patients with brain metastases was significantly higher than that in patients with primary breast cancer tissues (P<0.01), and it was correlated with tumor TMN stage in breast cancer patients. MDA-MB-231 cell lines with stable COX-2 over-expression/knockout were successfully constructed. Over-expression of COX-2 promoted the migration and invasion of MDA-MB-231 cells (all P<0.01), and significantly increased the expressions of MMP2, MMP1, N-cadherin and vimentin (all P<0.01), but exerted insignificant effect on cell proliferation. The effect of COX-2 silence exerted the opposite effect and promoted cell proliferation (P<0.05). Conclusion: COX-2 is highly expressed in brain metastatic breast cancer tissues, which may promote the migration and invasion of breast cancer MDA-MB-231 cells by regulating EMT processes.

ABSTRACT

Objective@#This study aims to investigate the menarcheal age of female junior middle school students in Tianjin and associated factors, providing suggestions for further development of adolescence education on physiological and mental health.@*Methods@#A total of 4 127 junior middle school girls in Tianjin area were selected by stratified random sampling method, and investigated by the method of physical examination and questionnaire survey, results were analyzed.@*Results@#There were 1 383 girls reported menarche. Mean age at menarche was(12.68±1.19) years old; One-way ANOVA showed that girls with higher family income, higher parental education had earlier menarcheal age(F=4.97, 9.52, 10.64, P<0.05). It showed that the tendency that obesity group and over-weight group was higher in the rate of menarche than that of normal group and marasmus group(F=4.20, P<0.05). However, different time on watching TV, computer or celephone and sleeping was found to be unrelated with age at menarche(P>0.05). Kruskal Wallis H test showed that girls whose mothers’ AAM was earlier had earlier menarcheal age(H=82.94, P<0.05). According to age, girls were divided into groups of 10-11, 11-12, 12-13 and 13-14 years old. Girls in each age group were divided into the menstruation menarche group and the non-menstruation menarche group. The results showed that the levels of height, weight, BMI, waist circumference, hip circumference, and the skin fold thickness in menstruation group were higher than those in non-menstruation group(t=2.18-10.93, P<0.05). After that, girls of each group were divided into four group:marasmus group, the normal group, the over-weight group and the obesity group according to BMI(χ2=34.66,13.37,11.09,12.60,P<0.05).@*Conclusion@#Female junior middle school students’ menarcheal age in Tianjin is related to family income, parents’education, mother’s age at menarche, obesity and physical exercise frequency.

ABSTRACT

Background: Osmanthus fragrans is an important ornamental tree and has been widely planted in China because of its pleasant aroma, which is mainly due to terpenes. The monoterpenoid and sesquiterpenoid metabolic pathways of sweet osmanthus have been well studied. However, these studies were mainly focused on volatile small molecule compounds. The molecular regulation mechanism of synthesis of large molecule compounds (triterpenoids) remains unclear. Squalene synthase (SQS), squalene epoxidase (SQE), and beta-amyrin synthase (BETA-AS) are three critical enzymes of the triterpenoid biosynthesis pathway. Results: In this study, the full-length cDNA and gDNA sequences of OfSQS, OfSQE, and OfBETA-AS were isolated from sweet osmanthus. Phylogenetic analysis suggested that OfSQS and OfSQE had the closest relationship with Sesamum indicum, and OfBETA-AS sequence shared the highest similarity of 99% with that of Olea europaea. The qRT-PCR analysis revealed that the three genes were highly expressed in flowers, especially OfSQE and OfBETA-AS, which were predominantly expressed in the flowers of both "Boye" and "Rixiang" cultivars, suggesting that they might play important roles in the accumulation of triterpenoids in flowers of O. fragrans. Furthermore, the expression of OfBETA-AS in the two cultivars was significantly different during all the five flowering stages; this suggested that OfBETA-AS may be the critical gene for the differences in the accumulation of triterpenoids. Conclusion: The evidence indicates that OfBETA-AS could be the key gene in the triterpenoid synthesis pathway, and it could also be used as a critical gene resource in the synthesis of essential oils by using bioengineered bacteria.

ABSTRACT

Abstract This study aimed to determine the association between the polymorphisms and haplotypes in the xeroderma pigmentosum group D (XPD) gene and the risk of pancreatic cancer in the Chinese Han population. SNaPshot was used for genotyping six SNP sites of the XPD gene. Comparisons of the correlations between different genotypes in combination with smoking and the susceptibility to pancreatic cancer were performed. Individual pancreatic cancer risk in patients who carry mutant C alleles (AC, CC, and AC+CC) at rs13181 increased (p < 0.05). Taking non-smoking individuals who carry the AA genotype as a reference, and non-smoking individuals who carry mutant allele C (AC+CC), the risk of pancreatic cancer increased by 3.343 times in individuals who smoked ≥ 20 cigarettes daily, 3.309 times in individuals who smoked ≥ 14 packs per year, 5.011 times in individuals who smoked ≥ 24 packs per year, and 4.013 times in the individuals who smoked ≥ 37 packs per year (P < 0.05). In addition, haplotype analysis revealed that haplotype AGG, which comprised rs13181, rs3916874 and rs238415, was associated with a 1.401-fold increase in pancreatic cancer risk (p < 0.05). We conclude that the polymorphism of XPD Lys751Gln (rs13181) in combination with smoking contributes to increased risk of pancreatic cancer in the Chinese Han population. Haplotype AGG might be a susceptibility haplotype for pancreatic cancer.

ABSTRACT

Endoplasmic reticulum (ER) stress is a critical molecular mechanism involved in the pathogenesis of sepsis. Hence, strategies for alleviating this stress may be essential for preventing cardiovascular injuries under sepsis. Adiponectin is secreted by adipocytes and its levels are decreased in sepsis. The purpose of this study was to investigate the protective effects of adiponectin treatment on endothelial cells and its mechanism. Male Wistar rats underwent cecal ligation and puncture (CLP) before being treated with adiponectin (72 and 120 μg/kg). The levels of malondialdehyde (MDA) in plasma, histological structure, and apoptosis of endothelial cells were evaluated. In vitro, human umbilical vein endothelial cells (HUVECs) were treated with adiponectin at 10 and 20 μg/mL for 24 h after stimulation by lipopolysaccharide (LPS). The levels of reactive oxygen species (ROS), ultrastructure, rate of apoptosis, the expression of inositol-requiring enzyme 1α (IRE1α) protein, and its downstream molecules (78 kDa glucose-regulated protein (GRP78), C/EBP homologous protein (CHOP), and caspase-12) were detected. The results showed that the levels of MDA and ROS induced by CLP or LPS stimulation were increased. Furthermore, endothelial cell apoptosis was increased under sepsis. The IRE1α pathway was initiated, as evidenced by activated IRE1α, increased GRP78, and up-regulated CHOP and caspase-12 in HUVECs. Following treatment with adiponectin, the number of apoptotic endothelial cells was markedly decreased. These findings demonstrated that treatment with adiponectin decreased apoptosis of endothelial cells caused by sepsis by attenuating the ER stress IRE1α pathway activated by oxidative stress.

ABSTRACT

The incidence of calcific aortic valve disease (CAVD) has increased dramatically as a result of the decline in rheumatic fever and the increase of the aging population, and by now CAVD has become the most common cardiac valve disease in the elderly in China. CAVD used to be thought as an irreversible passive process relating to valve degeneration and calcium accumulation. However, latest research has shown that CAVD is a complex active process, which involving vascular endothelial injury, lipid infiltration, chronic inflammation, matrix remodeling, cell differentiation, progressive bone formation, and neovascularization. Besides, genetic mutation also play a significant role in the process. Novel therapeutic target and technology such as transcatheter aortic valve implantation have been developed, which casts new lights on CAVD prevention and treatment. This review focused on the current understanding of the pathogenesis and future diagnosis/ therapies of CAVD.

ABSTRACT

The efficacy material base of traditional Chinese medicines (TCMs) is those constituents absorbed in blood and show the efficacy of TCMs after oral administration of a TCM formula. In TCM, formula consisted of more than one herbal drug is the clinical medication form which corresponding to TCM syndrome. The efficacy material base of TCMs had to be found in the condition of compatibility and efficacy of TCM formula. Therefore we take the biological characters of TCM syndrome as a research starting point, taking formula as object, through the integration of serum pharmacochemistry of TCM methods and metabolomics technologies, establish a system research methodology of the efficacy material basis in vivo--Chinmedomics. The use of metabolomics technology is used to fully understand nature biology on syndromes or disease, identify biomarkers for disease to bridging disease animal model, establishing the biological evaluation system of traditional Chinese medicine. On the basis of the validity of the premise, the use of serum pharmacochemistry of TCM to analysis in vivo directly substance after oral prescription and dynamic law, combined with changes law of the endogenous disease biomarkers (pharmacodynamic markers of TCM), Though establishing two variable correlation analysis method between Chinese chemical compositions in serum exogenous and endogenous biomarkers, to extract TCM compositions highly correlated with the endogenous marker as potential basis for traditional Chinese medicines, and to biological validation to determine the efficacy material basis of TCM.

ABSTRACT

OBJECTIVE: Epstein-Barr virus (EBV) is a ubiquitous human γ-herpes virus, which can adapt and evade host immune defense. Dendritic cells (DCs) play a pivotal role in the initiation and maintenance of immune responses. This study investigated the effects of EBV on cord blood monocytes derived DCs (CBDC). METHODS: Monocytes were isolated from cord blood and cultured in medium containing recombinant IL-4 and GM-CSF to induce DCs development. B95-8 supernatant was added in monocytes culture medium for EBV infection at day 0. Phenotypic characterization of DCs, apoptotic cells, and mitochondrial membrane potential (MMP) were detected by flow cytometry. The morphology was observed by Hoechst 33258 staining and TUNEL staining, the expression of X-linked inhibitor of apoptosis protein (XIAP) was detected by Western blotting assay and caspase 3, 8 and 9 activity was measured. RESULTS: Phenotypic characterization of DCs was changed in EBV-treated group. Chromatin condensation and DNA fragmentation were observed in EBV induced CBDC apoptosis. In addition, caspase 3, caspase 8, and caspase 9 activation were enhanced in the EBV-treated group. This was accompanied by the loss of MMP. Furthermore, XIAP expression was down-regulated in the EBV-treated group and compared to mock-infected group. CONCLUSION: These results suggested that EBV could inhibit CBDC phenotypic differentiation, and induce CBDC apoptosis in caspase-dependent manner with involvement of the mitochondrial pathway. This might help EBV to evade host immune responses to establish persistent infection.
