Objective To research the relationship between quality of life among the elderly with chronic periodontitis (CP) and the severity of CP.Methods A total of 471 elderly patients seeking treatment in the affiliated Stomatology Hospital of Kunming Medical University from September 2013 to January 2014 and their companions were investigated using the questionnaire according to the Chinese version of the Oral health Impact Profile-14.Those who diagnosed with CP were separated into two groups according to Community periodontal index (CPI) through periodontal examination.Group A was diagnosed with the early CP,and Group B was diagnosed with the late CP.Database was established by Epidata and statistical analysis was performed by SPSS.Results A total of 237 elderly patients with early CP and 139 with late CP were recorded.The mean OHIP-14 scores of the former were 14.36 ± 6.67,and the score of the later were 15.65 ± 7.12 relatively.The two groups who lived through negative effects were compared.The results suggested in the 14 items of OHIP-14.The statistical significance existed in the following 4 items,obvious pain appeared,uncomfortable when eating anything,unsatisfied with own diet,become easy to lose one's temper to others (P＜0.05).Conclusion OHR-QOL of elderly patients with the late CP is lower than that of those with the early CP.

Objective:To explore bromodomain and extra-terminal (BET) inhibition in the regulation of vascular endothelial cells activation and early atherosclerosis formation and its potential molecular mechanisms.Methods:1.Human umbilical vein endothelial cells (HUVEC) and mouse heart endothelial cells (MHEC) were isolated,and tumor necrosis factor α (TNFα) was used to activate in flammatory genes transcription in the presence or absence of JQ1,a specific BET inhibitor.The groups are as follows:(1)Normal control group;(2) TNFα(25 ng/mL)group;(3) TNFα+JQ 1 group.The gene mRNA and protein expression of inflammatory cytokines were measured by both real-time PCR and flow cytometry (FCM).2.LDL receptor-deficient (LDLR-/-) mice were randomly divided into 2 groups:JQ1 group (n=8,JQlintraperitoneal,50 mg/kg,daily) and control group (n=8,DMSO,daily).After 8 weeks feeding with high cholesterol diet,vascular cell adhesion molecule-1 (VCAM-1) expression in aortic arch was measured by immunohistochemistry.The activity of nuclear factor kappa B (NF-κB) signaling was monitored by 5XκB luciferase reporter assay in HEK293.Results:TNFα dramatically induced the mRNA and protein expression of inflammatory genes and JQ 1 significantly downregulated the induction of them (E-selectin,P-selectin,VCAM-1,IL-8)(P＜0.01).Immunohistochemistry detection indicated that JQ1 significantly downregulated the expression of VCAM-1 in aortic arch induced by 8 weeks high cholesterol diet feeding comparing to control group.In addition,BET bromodomain inhibition downregulated TNFα upregulated NF-κB transcriptional activity (P＜0.01).Conclusions:Our study demonstrated that BET bromodomain was involved in NF-κB mediated inflammatory genes expression;inhibition of BET bromodomain suppressed vascular endothelial activation in vitro,and attenuated early atherogenesis in vivo.

Objective: To investigate the causal relationship between gut microbiota and constipation using Mendelian randomization (MR) method. Methods: Genetic variation data of gut microbiota were obtained from the MiBioGen Consortium database. The genetic variation data of constipation were sourced from the IEU Open GWAS database. A forward MR analysis was performed using the inverse-variance weighted (IVW) method with 2 511 SNPs associated with gut microbiota as instrumental variables, and constipation as study outcome, and a reverse MR analysis was performed with 13 microbiota-associated SNPs as instrumental variables and gut microbiota as study outcome. The heterogeneity was assessed using the Cochran test, reverse causation of SNP were examined using MR Steiger test, and the horizontal pleiotropy was assessed using the MR-PRESSO test and MR-Egger regression. In addition, the robustness of the results was verified with the leave-one-out. Results: Forward MR analysis results showed that an increased abundance of genus Coprococcus1 driven by host genetics was associated with a decreased risk of constipation (OR=0.791, 95%CI: 0.709-0.884), and increased abundance of phylum Bacteroidetes driven by host genetics was associated with an increased risk of constipation (OR=1.240, 95%CI: 1.102-1.394). Cochran test detected no heterogeneity (both P>0.05), MR Steiger test was not revealed reverse causation of SNP, and neither the MR-PRESSO test nor the MR-Egger regression revealed horizontal pleiotropy of instrumental variables (all P>0.05), and the leave-one-out method confirmed the robustness of results. Reverse MR analysis showed no association between gut microbiota and constipation (both P>0.05). Conclusion Genus Coprococcus1 and phylum Bacteroidetes in the gut microbiota are associated with constipation.

Objective To evaluate efficacy and mechanism of Anluohuaxian pilule combined with interferon-γ in the treatment of schistosomal liver fibrosis. To preliminarily study on the relationship of pigment deposition in liver and schistosomal liver fibrosis. Methods Thirty Kunming mice were divided into the normal control group, the infection control group and the combination of Anluohuaxian pilule and Interferon-γ treated group. Schistosomal liver fibrosis model was established by infection with 40 Schistosoma japonicum cercariae. The treated group was treated by combination of Anluohuaxian pilule and Interferon-γ for 8 weeks. The changes of pigment deposition and hepatic egg granuloma in Schistosoma japonicum infected mice were observed. Expressions of collagen Ⅰ and Ⅲ were detected by immunohistochemistry. Transforming growth factor (TGF)-β1 was detected by fluorescent polymerase chain reaetion(PCR). Histopathology and computer image analysis were applied to evaluate the change in the liver tissues. Results The amount of pigment deposition in liver was related to the expression of TGF-β1 mRNA (correlation coefficient = 0. 8). Compared to the infection control group, combination of Anluohuaxian pilule and Interferon-γ can lessen hepatic fibrosis(P<0.05). The combination therapy can also make pigment deposition less and hepatic granuloma smaller than the infection control group(P<0. 05). Conclusions Pigment deposition in liver is related to the expression of TGF-β 1. Combination of Anluohuaxian pilule and Interferon-γ can lessen hepatic fibrosis in mice infected with Schistosoma japonicum. It's one mechanism to of the combination therapy down-regulate the expression of collagen Ⅰ, Ⅲ and TGF-β 1.

AIM: To investigate the effects of fibroblast growth factor 10 ( FGF10 ) on lipopolysaccharide ( LPS)-induced microglial activation .METHODS:Mouse BV2 microglial cells were maintained in DMEM in a humidified incubator with 95%/5%( V/V) mixture of air and CO 2 at 37℃.The medium was changed every 1 or 2 d.The cells were digested and passaged every 4 or 5 d.The BV2 microglial cells were first pretreated with FGF 10 (1 mg/L) for 30 min and then stimulated with LPS (500 μg/L).The medium and the cells were collected at different time points .The morphologi-cal changes of microglia were visualized under microscope .To evaluate the microglial activation , the transcription and pro-duction of proinflammatory factor tumor necrosis factor-α( TNF-α) were examined by real-time quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA), respectively.RESULTS:The morphology of control BV2 microglia showed circular or oval shape .After exposure to LPS for 24 h, the microglia revealed spindle shaped or multipolar morphology , and the percentage of activated cells was significantly increased compared with control group.Pretreatment with FGF10 successfully inhibited the morphological change from normal to activated shape .LPS sti-mulation for 6 h significantly increased the transcription of TNF-α, while FGF10 pretreatment remarkably reversed the effect.In addition, the production of TNF-αincreased in the presence of LPS stimulation for 24 h compared with control group.Pretreatment with FGF10 suppressed LPS-induced TNF-αexpression.CONCLUSION: Pretreatment with FGF10 inhibits the morphological change from normal to activated shape , and remarkably suppressed the transcription and produc-tion of TNF-α.FGF10 successfully suppresses LPS-induced BV2 microglial activation , indicating that FGF10 is a therapeu-tic agent for the treatment of glia-mediated neuroinflammatory diseases .

Objective To analyze the mortality rate and probability of premature death caused by four major noninfectious chronic diseases (NCDs)in Linyi City from 2013 to 2021, and to provide data support for scientific formulation of chronic disease prevention and control strategy. Methods The mortality data of major chronic diseases in Linyi City from 2013 to 2021 were analyzed. The crude mortality, age-standardized mortality and premature death probability were calculated. The annual percent change (APC) was adopted to analyze the temporal trend of mortality and probability of premature death. Results The average annual crude mortality of four major NCDs was 538.98/100,000, and the age-standardized mortality was 387.3/100,000. The crude mortality rate increased from 517.37/100 000 in 2013 to 563.13/100 000 in 2021 (APC=0.89％, P=0.01). The age-standardized mortality rate decreased from 410.19/100,000 to 364.92/100,000 (APC=-1.8％, P=0.01). The crude mortality and age-standardized mortality of four major NCDs in males were higher than those in females (P<0.05). The average annual probability of premature death caused by four major NCDs was 13.37%. The probability of premature death decreased from 14.49％ in 2013 to 12.32％ in 2021（APC=-2.1％, P=0.00）. From 2013 to 2021, the probability of premature death from malignant tumors, cardiovascular and cerebrovascular diseases, and chronic respiratory diseases in Linyi City dropped from 6.14%, 7.47%, and 1.21% to 5.52%, 6.46%, and 0.5%, respectively (APCs were -1.2%, -2.1%, and -11.3%, respectively, and P values were 0.04, 0.00, and 0.00, respectively). The probability of premature death from diabetes remained stable. The probability of premature death caused by four major NCDs in males was higher than that in females (P<0.05). Conclusion The probability of premature death of the four major NCDs in Linyi has showed a downward trend during 2013-2021. It is suggested to strengthen the prevention and control of diabetes in the next step.

PURPOSE: Elevation in serum alanine aminotransferase (ALT) levels is a biomarker for metabolic syndrome (MS); however, the relationship has not been fully investigated within the reference interval of ALT levels. Our objective was to explore the relationship between serum ALT levels within the reference interval and MS in Chinese adults. MATERIALS AND METHODS: This cross-sectional study included 16028 adults, who attended routine health check-ups at Shengli Oilfield Central Hospital from January 2006 to March 2012. The reference interval of serum ALT level was defined as less than 40 U/L. Logistic regression models and restricted cubic spline were used to evaluate the association of ALT with MS. RESULTS: The prevalence of MS in the total population was 13.7% (6.4% for females and 18.4% for males). Multiple logistic regression showed that ALT levels were positively associated with MS after adjustment for potential confounding factors. The odds ratio of MS in the top quartile was 4.830 [95% confidence interval (CI): 2.980–7.829] in females and 3.168 (95% CI: 2.649–3.790) in males, compared with the ALT levels in the bottom quartile. The restricted cubic spline models revealed a positive non-linear dose-response relationship between ALT levels and the risk of MS in women (p for nonlinearity was 0.0327), but a positive linear dose-response relationship in men (p for nonlinearity was 0.0659). CONCLUSION: Serum ALT levels within the reference interval are positively associated with MS in a dose-response manner. Elevated ALT levels, even within the reference interval, may reflect early dysmetabolic changes.

Objective:To systematically review the resilience intervention in patients with cancer, so as to evaluate its effectiveness. Methods: Studies published until March 2017 were searched in CNKI, VIP, WanFang Data, CBM, PubMed, Cochrane library, Wiley Online Library, Elsevier ScienceDirect, Springer Link and EBSCO. The randomized controlled trials(RCTs) about resilience intervention in patients with cancer were included. Two reviewers independently performed screening, quality assessment and data extraction Qualitative synthesis was adopted to review the resilience intervention and to evaluate its effectiveness of included studies. Results: Totally 14 studies were included for the analysis. Eight studies evaluated the effectiveness of individuation intervention, and 6 studies evaluated the effectiveness of group intervention. Thirteen studies suggested that individuation intervention and group intervention might significantly improve the resilience in cancer patients. Conclusion: The results suggest individuation or group intervention may improve the resilience in patients with cancer. Current studies on resilience intervention are limited, and the measure has been taken seems lacks of high-quality research design.

Objective To explore the chain mediating effect of mastery and self-efficacy between optimism and resilience of breast cancer patients.Methods Totally 262 breast cancer patients were investigated with general information questionnaire,resilience scale (RS-14),mastery scale for Chinese version (MSC),general self-efficacy scale (GSES) and revised life orientation test (LOT-R).Causual steps and Bootstrap method were used to test the chain mediating effect of mastery and self-efficacy between optimism and resilience.Results The media score of the participants was 18 for optimism,and the average score of the participants was 27.1±4.6 for mastery,26.0±5.9 for self-efficacy,76.6± 13.9 for resilience.There existed a significant difference in RS-14 scores among the patients with different family relationships,family income,and form of payment (all P＜0.05).Correlation analysis showed that optimism,mastery,self-efficacy,and resilience were positively correlated with each other(r=0.57-0.74,all P＜ 0.01).Mediation modeling analysis showed that optimism had a direct effect on resilience.The effect value was 0.361,and the effect was 49.7％.Mastery and self-efficacy mediation effect value were 0.123 and 0.162,and the mediation effect were 16.9％ and 22.3％.While chain mediating effect of mastery-self-effcacy was also significant,and the mediation effect value was 0.081 and the mediation effect was 11.1％.Conclusion Optimism influences breast cancer patients' resilience,not only through the direct path,but also through the indirect path of mastery and self-efficacy,as well as the chain mediating path between these two variables.
