BACKGROUND: The hemoglobin glycation index (HGI) was developed to quantify glucose metabolism and individual differences and proved to be a robust measure of individual glycosylated hemoglobin (HbA1c) bias. Here, we aimed to explore the relationship between different HGIs and the risk of 5-year major adverse cardiovascular events (MACEs) by performing a large multicenter cohort study in China. METHODS: A total of 9791 subjects from the Risk Evaluation of Cancers in Chinese Diabetic Individuals: a Longitudinal Study (the REACTION study) were divided into five subgroups (Q1-Q5) with the HGI quantiles (≤5th, >5th and ≤33.3th, >33.3th and ≤66.7th, >66.7th and ≤95th, and >95th percentile). A multivariate logistic regression model constructed by the restricted cubic spline method was used to evaluate the relationship between the HGI and the 5-year MACE risk. Subgroup analysis between the HGI and covariates were explored to detect differences among the five subgroups. RESULTS: The total 5-year MACE rate in the nationwide cohort was 6.87% (673/9791). Restricted cubic spline analysis suggested a U-shaped correlation between the HGI values and MACE risk after adjustment for cardiovascular risk factors ( χ2 = 29.5, P <0.001). After adjustment for potential confounders, subjects with HGIs ≤-0.75 or >0.82 showed odds ratios (ORs) for MACE of 1.471 (95% confidence interval [CI], 1.027-2.069) and 2.222 (95% CI, 1.641-3.026) compared to subjects with HGIs of >-0.75 and ≤-0.20. In the subgroup with non-coronary heart disease, the risk of MACE was significantly higher in subjects with HGIs ≤-0.75 (OR, 1.540 [1.039-2.234]; P = 0.027) and >0.82 (OR, 2.022 [1.392-2.890]; P <0.001) compared to those with HGIs of ≤-0.75 or >0.82 after adjustment for potential confounders. CONCLUSIONS We found a U-shaped correlation between the HGI values and the risk of 5-year MACE. Both low and high HGIs were associated with an increased risk of MACE. Therefore, the HGI may predict the 5-year MACE risk.

Objective:To identify differentially expressed genes (DEGs) associated with the progression of synovitis in RA by using bioinformatics analysis and explore the effects of DMARDs such as methotrexate, tocilizumab and rituximab on the DEGs in RA synovium.Methods:RA expression profile microarray data GSE7307、GSE12021、GSE55457、GSE55235、GSE77298、GSE89408 were acquired from the public gene chip database (GEO), including 113 synovial tissue samples from RA and 70 healthy controls (HC). At the same time, synovial expression microarrays GSE45867, GSE24742 and GSE97165 after DMARDs treatment were obtained. These data included 8 samples treated with methotrexate, 12 treated with tocilizumab, 12 treated with rituximab and 19 treated with combined tDMARDs. R software was used to screen DEGs and Venn plots using gene ontology function enrichment and Kyoto encyclopedia of genes and genomes pathway enrichment analysis. Hub genes were selected by STRING online analysis tool and Cytoscape software.Results:Compared with HC, 797 DEGs were up-regulated and 434 DEGs were down-regulated in the synovial tissue of RA. These DEGs were mainly enriched in T cell activation, immune response-activating cell surface receptor signaling pathway. Using Cytoscape and cytoHubba to obtain 5 sets of DEGs based on the STRING database model, the degree algorithm screened out 10 hub genes: LCK, SYK, PTPRC, HLA-DRA, LYN, NCAPG, TOP2A, JUN, CXCR4, CCNB1. Methotrexate treatment significantly up-regulated 20 DEGs and down-regulated 30 DEGs. Rituximab treatment up-regulated 100 DEGs and down-regulated 55 DEGs. Tocilizumab treatment up-regulated 91 DEGs and down-regulated 317 DEGs. These altered DEGs were enriched in regulating cell adhesion, leukocyte-cell adhesion, leukocyte transfer, and insulin-like growth factor receptor signaling pathways. It was worth noting that after treatment, a total of 306 high-expressing DEGs were down-regulated, and 36 low-expressing DEGs were up-regulated.Conclusion:LCK, insulin-like growth factor receptor signaling pathway, etc. are the responsible molecular mechanisms and key pivot genes for the occurrence and development of RA, and the treatment of DMARDs, which are closely related to the response of RA to the treatment of DMARDs.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by severe synovial inflammation and cartilage damage. Despite great progress in RA therapy, there still lacks the drugs to completely cure RA patients. Herein, we propose a reprogrammed neutrophil cytopharmaceuticals loading with TNFα-targeting-siRNA (siTNFα) as an alternative anti-inflammatory approach for RA treatment. The loaded siTNFα act as not only the gene therapeutics to inhibit TNFα production by macrophages in inflamed synovium, but also the editors to reprogram neutrophils to anti-inflammatory phenotypes. Leveraging the active tendency of neutrophils to inflammation, the reprogrammed siTNFα/neutrophil cytopharmaceuticals (siTNFα/TP/NEs) can rapidly migrate to the inflamed synovium, transfer the loaded siTNFα to macrophages followed by the significant reduction of TNFα expression, and circumvent the pro-inflammatory activity of neutrophils, thus leading to the alleviated synovial inflammation and improved cartilage protection. Our work provides a promising cytopharmaceutical for RA treatment, and puts forward a living neutrophil-based gene delivery platform.

Parkinson′s disease is a neurodegenerative disease characterized by bradykinesia, resting tremor, and hypermyotonia. Its pathological features are the loss of nigra dopamine neurons and the abnormal aggregation of α-synuclein, and there is currently no treatment that blocks the progression of the disease. Gene therapy, by increasing the expression of neurotrophic factors and increasing levels of neurotransmitters, may slow, terminate, or even reverse the progression of the disease, so it gets more attention. This article reviews the progress of registered clinical research on gene therapy for Parkinson′s disease.

Purpose: Chronic stress and related hormones are key in cancer progression. Peroxisome proliferator-activated receptor γ (PPARγ) and its agonists was reported that inducing anti-tumor effect. However, the function of PPARγ in pro-tumorigenic effects induced by chronic stress in breast cancer remains unknown. Herein, we have characterized a novel role of PPARγ and vascular endothelial growth factor (VEGF)/fibroblast growth factor 2 (FGF2) signals in breast cancer promoted by chronic stress. Materials and Methods: We performed experiments in vivo and in vitro and used bioinformatics data to evaluate the therapeutic potential of PPARγ in breast cancer promoted by stress. Results: Chronic stress significantly inhibited the PPARγ expression and promoted breast cancer in vivo. VEGF/FGF2-mediated angiogenesis increased in the chronic stress group compared to the control group. PPARγ agonist pioglitazone (PioG) injection offset the pro-tumorigenic effect of chronic stress. Moreover, specific β2-adrenergic receptor (β2R) antagonist ICI11-8551 inhibited the effect of chronic stress. In vitro, norepinephrine (NE) treatment had a similar tendency to chronic stress. The effect of NE was mediated by the β2R/adenylate cyclase signaling pathway and suppressed by PioG. PPARγ suppressed VEGF/FGF2 through reactive oxygen species inhibition. Bioinformatics data confirmed that therewas a lowPPARγ expression in breast invasive carcinoma. Lower PPARγ was associated with a significantly worse survival. Conclusion β2R activation induced by chronic stress and related hormones promotes growth and VEGF/FGF2-mediated angiogenesis of breast cancer by down-regulating PPARγ. Our findings hint that β receptor and PPARγ as two target molecules and the novel role for their agonists or antagonists as clinical medicine in breast cancer therapy

Objective To explore the characteristics of trunk muscle activity in persons with Parkinson's disease (PD) in search of better treatments for abnormal posture.Methods Ninety persons with PD of different severity and 8 normal controls were studied using surface electromyography (sEMG).A sixteen-lead sEMG instrument was used to collect sEMG amplitudes from the bilateral thoracic erector spinae,lumbar erector spinae,external oblique and rectus abdominis muscles when the subjects were lying,standing and walking.Results Compared with the control group,a significant increase was observed in the sEMG amplitude of the lumbar erector spinal muscle [(18.56±14.57) μV] and rectus abdominis muscles [(24.00±18.80)μV] of the PD group when lying.Significant relative increases in (P＜0.05),of the external oblique muscles were observed [(27.87± 11.49)μV] when standing (P＜0.05),and in the thoracic erector spinae muscle [(58.74±29.69)μV] and external oblique muscles [(59.01± 25.20) μV] increased when walking (P＜0.05).Compared with the control group,the sEMG activity of the external oblique muscles was significantly elevated in PD patients at Hoehn and Yahr stage 1 to 1.5 when walking.One or more of the trunk muscle groups showed significantly greater activity in the PD patients in Hoehn and Yahr stage 2 or 3 in all three positions.Conclusions The sEMG activities of the extensor and flexor muscles increase simultaneously in PD patients.More trunk muscles are involved in PD patients with higher H-Y grades.These findings provide a neurophysiological basis for the customizaton of rehabilitation therapy for patients with Parkinson's disease and for the precise selection of muscles for botulinum toxin injection.

Objective: To explore the current residents training of standardized training program and their attitude towards the program, so as to provide suggestions for optimizing the training system. Methods: Questionnaire surveys were carried out among 1 427 resident physicians from 10 hospitals in 7 provinces and cities between March 2017 to May 2017. The investigation covered demographic information, current work and study, training effect and problems. Statistical description and χ² test were used for analysis. Results: Only 18.08% of the residents in standardized training program considered it as unnecessary, while 80% of them agreed with its effectiveness in improving their clinical skills and humanistic quality. 67.29% of them thought of resignation because of low income and high work pressure. Compared with " double track" residents, those of " double-track integration" complained of lower income and higher workload. Conclusions Chinese residents in standardized training program had a positive attitude towards the training system. However, the measures should be improved to prevent from possible occupational burnout. It is suggested that professionalism and professional identity education be improved, and subjective well-being feeling of residents be focused to avoid burnouts.

Objective To analyze the acoustic features of patients with Parkinson's disease (PD),and to explore the correlation between the acoustic features and the severity and course of disease.Methods Fifty-two patients with PD from the Tongji Hospital Affiliated to Tongji Medical University and the Ninth People's Hospital Affiliated to the Medical College of Shanghai Jiaotong University from August to December 2015 were enrolled into this study.Thirty-two age-matched healthy people served as control group.PD patients were tested with Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn-Yahr (H-Y) staging.And all the patients were tested with Mini-Mental State Examiantion (MMSE) and Voice Handicap Index (VHI).The voice samples of all subjects were collected and the frequency perturbation (jitter),amplitude perturbation (shimmer),and harmonic-to-noise ratio (NHR) were analyzed using a vocal assessment.Fundamental frequency (F0),standard deviation of fundamental frequency (SDF0) and formant ratio (F2i/F2u) were analyzed using a real-time speech measuring instrument.The acoustic parameters of the two groups were compared and the correlation between the parameters of the patients and the disease and course of disease was analyzed.Results Subjective assessment using VHI showed a total of 24 VHI abnormalities (46％) in the PD group,including 13 males (54％),11 females (46％).No VHI abnormalities were found in the control group.Among the parameters analyzed by objective acoustic method,compared with the control group (female/a/1.43(1.19,1.92),/i/3.39(1.49,9.85),/u/1.46(1.23,3.85);male/a/1.06(0.92,1.89),/u/1.30(1.07,1.64)),the SDF0 of the three vowels of the female patients in the PD group (/a/2.99(1.81,4.12),Z=5.429,P＜0.01;/i/10.89(5.47,22.20),Z=8.487,P＜0.01;/u/5.16(3.75,7.80),Z=7.138,P＜0.01) and /a/ and /u/ of the male patients in the PD group (/a/2.16(1.73,2.94),Z=4.858,P=0.002;/u/3.70(2.41,5.43),Z=7.664,P＜0.01) were significantly increased,and the F2i/F2u in the PD group (male 1.96±0.84,female 1.81± 1.14) was lower than that in the control group (male 3.48±0.70,female 4.14± 1.08),and the difference was statistically significant (t=-6.669,-6.844,P＜0.01).There were no statistically significant differences in frequency perturbation,amplitude perturbation,harmonic noise ratio and fundamental frequency.Only the fundamental frequency standard deviation of the sound parameters used in the study was correlated with the disease course of PD patients.After the severity of the disease was assessed by H-Y staging,the frequency perturbation (jitter),amplitude perturbation (shimmer) in the middle and late stage patients were higher than those in the early stage patients,and the difference of frequency perturbation in the three vowels was statistically significant,and the difference of amplitude perturbation in the vowels/i/and/u/was statistically significant.No correlation was found between the acoustic parameters and UPDRS score.Conclusions Consonance disorders are common in PD patients,and the changes in acoustic parameters are mainly manifested as the increase in the SDF0 and the decrease in the F2i/F2u.Acoustic parameters can be used as an effective indicator to evaluate the condition and course of PD patients,and further language tasks need to be added to clarify.
