Objective:To evaluate insulin sensitivity(IS)and pancreatic β-cell secretion function in the elderly, analyze the influencing factors, and compare these parameters with those observed in adults.Methods:A total of 301 participants were selected from the health examination population at the Geriatrics Endocrinology Department of Jiangsu Provincial People's Hospital, all of whom had no history of diabetes, between December 2018 and June 2021.Participants were categorized into elderly and adult groups based on age.Personal and medical histories were recorded, and various measurements, including height, weight, waist circumference, hip circumference, blood lipids, and nutritional metabolic indicators, were obtained.Body composition was assessed using dual-emission X-ray absorptiometry(DXA).The oral minimal model(OMM)method was utilized to derive the insulin sensitivity index(ISI), dynamic insulin secretion(Φd), static insulin secretion(Φs), total insulin secretion(Φt), and disposition index(DI).Participants were grouped according to the results of oral glucose tolerance tests.Finally, the factors influencing IS and pancreatic β-cell function were analyzed in both elderly and adult populations, as well as to identify any differences between the two groups.Results:Following adjustments for gender and body mass index(BMI), partial correlation analysis indicated a decrease in Φd, DI-Φd, and DI-Φt with advancing age( r=-0.219, -0.210, -0.187; P=0.005, 0.015, 0.017).In contrast, ISI, Φs, Φt, and DI-Φs showed no significant correlation with age.Although ISI levels were comparable between the elderly and adult groups, individuals newly diagnosed with diabetes in the elderly cohort exhibited higher DI-Φd, DI-Φs, and DI-Φt compared to those in the adult group after ISI correction.When incorporating age, high-density lipoprotein cholesterol(HDL-C), total muscle mass, the android to gynoid ratio(A/G), and fat mass index(FMI)into a binary Logistic regression model, the findings underscored FMI as a common risk factor for both elderly and adult cohorts concerning the ISI( OR=2.324, 1.773; P=0.032, 0.005).The A/G ratio was identified as a risk factor for DI-Φd in both age groups( OR=69 252.464, 407.653; P=0.012, 0.001).Furthermore, HDL-C was recognized as a protective factor for ISI( OR=0.024, P=0.012)in the elderly, while advancing age( OR=1.454, P=0.039)was found to be a risk factor for DI-Φs in this demographic.Total muscle mass and the A/G ratio were also acknowledged as risk factors for ISI( OR=1.054, 15.725; P=0.021, 0.026), with FMI serving as a risk factor for DI-Φs in the adult cohort( OR=1.826, P=0.035). Conclusions:The secretion function of pancreatic β-cells declines with age, whereas ISI remains unchanged.The factors affecting ISI, DI-Φd, and DI-Φs in elderly and adult populations show notable differences.This indicates that implementing targeted lifestyle interventions for distinct age groups may be more effective in preserving both ISI and pancreatic β-cell function.

Objective:To investigate the correlation of peripheral blood relative mitochondrial DNA copy number(mtDNAcn)with intrinsic capacity and body composition, and to identify potential biomarkers for healthy aging.Methods:Clinical data of 416 patients admitted to our hospital from September 2019 to June 2021 were consecutively collected.MtDNA was extracted from peripheral blood of these subjects, and mtDNAcn was determined by a real-time fluoresence quantitative reverse transcription-polymerase chain reaction(qRT-PCR). Intrinsic capacity assessment included 5 aspects that were exercise[Morse Fall Scale(MFS), Physiological Frailty Phenotype(PFP), Sarcopenia Questionnaire(SARC-CALF), Short Physical Performance Battery(SPPB), Time Up and Go Test(TUG)]; vitality[Mini Nutritional Assessment(MNA), Multidimensional Prognostic Index(MPI)]; cognition[Mini-Mental State Examination(MMSE)scale]; psychology[Geriatric Depression Scale(GDS), Self-rating Anxiety Scale(SAS)]; sensory capacities[Cumulative Illness Rating Scale-the Comorbidity Index(CIRS-CI)]. To assess body composition, dual-energy X-ray absorptiometry was used to measure body fat, including trunk fat, total body fat, fat in the abdominal region, fat in the buttock region, and then to calculate fat index(FMI)and limb skeletal muscle mass index(ASMI).Results:Spearman correlation analysis showed that mtDNAcn had a negatively correlation with age( r=-0.176, P<0.05). After adjustment for gender and body mass index, partial correlation analysis showed mtDNAcn were still negatively correlated with age( r=-0.144, P<0.05). Furthermore, mtDNAcn was significantly correlated with 4 m gait speed, the scores of SARC-CalF, MFS, MNA, MMSE, MPI and its sub-scale's Activities of Daily Living(ADL)and Short Portable Mental Status Questionnaire(SPMSQ)( r=0.171, -0.207, -0.163, 0.221, 0.184, -0.210, 0.241, -0.269, all P<0.05). After adjustment for age, gender and body mass index, partial correlation analysis showed mtDNAcn still had a significant correlation with gait speed, the scores of MFS, MNA, MPI and SPMSQ( r=0.170, -0.170, 0.148, -0.242, -0.188, all P<0.05). In addition, the Spearman correlation analysis showed that mtDNAcn was positively correlated with FMI, trunk fat, total body fat, abdominal fat and fat in the buttock region( r=0.168, 0.143, 0.175, 0.116, 0.199, all P<0.05). However, after adjustment for age and gender, mtDNAcn was only correlated with FMI, total body fat, fat in the buttock region( r=0.126, 0.131, 0.127, all P<0.05). On the other hand, multiple linear regression analysis showed that mtDNAcn was significantly correlated with age, gait speed, FMI, total body fat, fat in the buttock region, the scores of MFS, PFP, MNA and MPI( β=-0.191, 0.156, 0.126, 0.131, 0.125, -0.119, -0.145, 0.151, -0.171, all P<0.05). Conclusions:MtDNAcn is correlated with physical function, frailty, nutrition, falling, cognition and body composition, and may be considered as a biomarker for the evaluation of the locomotion and vitality of human intrinsic capacity.

Objective:To explore the effect sense of security and self-control on parent-child cohesion and externalizing problem behaviors in primary and middle school students.Methods:A total of 1 402 primary and middle school students were investigated with the problem behavior frequency scale(PBFS), family adaptability and cohesion scale(FACES-CV), security questionnaire(SQ) and brief self-control scale(BSCS). SPSS 25.0 and PROCESS v2.16 were used for statistical analysis, and common method deviation test, Pearson correlation analysis and intermediary effect analysis were used in the analysis.Results:Parent-child cohesion of primary and middle school students was positively correlated with security and self-control ( r=0.279, 0.303, both P<0.01), which was negatively correlated with externalizing problem behaviors ( r=-0.154, P<0.01). Security was positively correlated with self-control ( r=0.567, P<0.01). Security, self-control and externalizing problem behaviors were negatively correlated ( r=-0.147, -0.250, both P<0.01). The security and self-control of primary and middle school students played a partial mediating role between parent-child cohesion and externalizing problem behaviors.The mediating effect consisted of two paths: one was parent-child cohesion-self-control-externalizing problem behaviors, the other was parent-child cohesion-security-self-control-externalizing problem behaviors. The effect values of these two paths accounted for 20.52% and 20.26% of the total effect respectively. Conclusion:Parent-child cohesion not only directly affects the externalizing problem behaviors of primary and middle school students, but also indirectly affects the externalizing problem behavior through the independent mediating effect of self-control and the chain mediation of security-self-control.

Gliomas are the most common and malignant intracranial tumors in adults. Recent studies have revealed the significance of functional genomics for glioma pathophysiological studies and treatments. However, access to comprehensive genomic data and analytical platforms is often limited. Here, we developed the Chinese Glioma Genome Atlas (CGGA), a user-friendly data portal for the storage and interactive exploration of cross-omics data, including nearly 2000 primary and recurrent glioma samples from Chinese cohort. Currently, open access is provided to whole-exome sequencing data (286 samples), mRNA sequencing (1018 samples) and microarray data (301 samples), DNA methylation microarray data (159 samples), and microRNA microarray data (198 samples), and to detailed clinical information (age, gender, chemoradiotherapy status, WHO grade, histological type, critical molecular pathological information, and survival data). In addition, we have developed several tools for users to analyze the mutation profiles, mRNA/microRNA expression, and DNA methylation profiles, and to perform survival and gene correlation analyses of specific glioma subtypes. This database removes the barriers for researchers, providing rapid and convenient access to high-quality functional genomic data resources for biological studies and clinical applications. CGGA is available at http://www.cgga.org.cn.

Objective:To investigate the value of CD4/CD8 ratio and total B lymphocytes before radiotherapy in predicting the occurrence of radiation pneumonitis (RP) in patients with esophageal cancer and lung cancer.Methods:The clinicopathological data of 28 patients with esophageal and 16 patients with lung cancer undergoing radiotherapy from April 2018 to March 2020 in Hefei Cancer Hospital, Chinese Academy of Sciences were retrospectively analyzed, and the patients were divided into RP group ( n=16) and non-RP group ( n=28) according to whether RP occurred during and after treatment. The CD4/CD8 ratio and total B lymphocytes before radiotherapy between the two groups, and the CD4/CD8 ratio and total B lymphocytes before and after radiotherapy in the RP group were compared. Receiver operating characteristic curve was used to analyze the value of CD4/CD8 ratio and total B lymphocytes before radiotherapy in predicting RP. Results:The CD4/CD8 ratio before radiotherapy in the RP group was significantly lower than that in the non-RP group (0.993±0.179 vs. 1.708±0.170), with a statistically significant difference ( t=2.706, P=0.009); the total B lymphocytes in the RP group was significantly lower than that in non-RP group [(4.409±0.823)% vs. (8.153±1.017)%], with a statistically significant difference ( t=0.986, P=0.015). The CD4/CD8 ratio in the RP group was lower than that before radiotherapy when RP occurred (0.785±0.167 vs. 0.993±0.179), with no statistically significant difference ( t=1.376, P=0.189). The total B lymphocytes in the RP group was lower than that before radiotherapy when RP occurred [(3.487±1.018)% vs. (4.409±0.823)%], with no statistically significant difference ( t=0.804, P=0.433). The critical values of CD4/CD8 ratio and total B lymphocytes predicted RP were 0.580 and 0.357, respectively. The areas under the curve (AUC) of CD4/CD8 for predicting RP was 0.802 (95% CI: 0.653-0.932), the sensitivity was 89.29%, and the specificity was 68.75%. The AUC of total B lymphocytes for predicting RP was 0.694 (95% CI: 0.483-0.814), the sensitivity was 85.71%, and the specificity was 50.00%. The AUC of the two combined diagnostic method for RP was 0.834 (95% CI: 0.697-0.932), the sensitivity and specificity were 81.25% and 89.29%. AUC of the two combined tests was significantly higher than that of the single test, with statistically significant differences ( Z=1.115, P=0.046; Z=1.992, P=0.026). Conclusion:The CD4/CD8 ratio and total B lymphocytes in the RP group are lower than those in the non-RP group. The CD4/CD8 ratio and total B lymphocytes in the serum are of great significance in predicting the occurrence of RP in patients with malignant tumors receiving chest radiotherapy.

Unfolded protein response (UPR) is a stress response that is specific to the endoplasmic reticulum (ER). UPR is activated upon accumulation of unfolded (or misfolded) proteins in the ER's lumen to restore protein folding capacity by increasing the synthesis of chaperones. In addition, UPR also enhances degradation of unfolded proteins and reduces global protein synthesis to alleviate additional accumulation of unfolded proteins in the ER. Herein, we describe a cell-based ultra-high throughput screening (uHTS) campaign that identifies a small molecule that can modulate UPR and ER stress in cellular and

Objective To investigate the impact of hyponatremia on the short-term prognosis in patients with acute ST-elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI).Methods The present study included 324 patients with acute STEMI treated with PCI within 12 hours after admission from March 2014 to May 2016.Patients were divided into three groups according to plasma sodium levels (Na+) at admission:group A with Na+ ＜ 130 mmoL/L,group B with Na + 130-134 mmol/L and group C with Na + ≥ 135 mmol/L (normal plasma sodium level).Clinical data and biochemical variables were compared among the three groups.Logistic regression analysis was used to examine the correlation between plasma sodium levels and short-term prognosis.Results There were significant differences in age,fasting glucose,NT-proBNP,LVEF (left ventricular ejection fraction) and hsCRP (high sensitive C-reactive protein) among the three groups (P ＜ 0.05).The mortality in group A was obviously higher than that in Group B (20.0％ vs.6.3％,P ＜ 0.05) and in group C (20.0％ vs.6.0％,P ＜ 0.05).In addition,there were significant differences in rates of cardiogenic shock and acute renal failure among three groups.Logistic regression analysis showed that old age,low LVEF and hyponatremia were independent risk factors for 30-day mortality (P ＜ 0.05).Compared with group B,patients in group A had significantly high risks of death (OR =3.058,95％ CI:1.339-4.358,P =0.003),suggesting that the high risk of 30-day mortality associated with the severity of hyponatremia.Conclusions At admission,the hyponatremia in patients with acute STEMI treated with PCI is an independent risk factor for 30-day mortality,and prognosis worsens with the severity of hyponatremia.
