Objective To study the relationships between retinal microvascular disease and acute coronary event (ACE) among aged people. Methods A controlled study for senile people in communities was conducted. Xinglong Zhuang Coal Mine Community in Jining city, Shandong province was chosen to carry out the study, and the residents in that area aged≥60 years were asked to take questionnaire survey, physical and laboratory examinations. There were 139 cases met the diagnostic criteria of ACE being in the observation group, and 1 509 cases without ACE were assigned in the control group. The gender, age, smoking, alcohol intake, hypertension, diabetes mellitus, education, physical exercise, retinal microvascular disease, fasting blood-glucose, high density lipoprotein cholesterin (HDL-C), low density lipoprotein cholesterin (LDL-C), triacylglycerol (TG), systolic pressure, diastolic pressure, body mass index (BMI) were collected in the two groups to perform univariate analysis. Multivariate non-conditional logistic regression analysis was used for the factors with statistical significance to screen out the independent risk factors that could affect the occurrence of ACE. Results The univariate analysis showed:the risk factors that might cause the occurrence of ACE included age, gender, smoking, hypertension, diabetes mellitus, LDL-C, systolic pressure, diastolic pressure, BMI, and retinal microvascular disease (P<0.05 or P<0.01). In the ACE patients of observation group, the rates of presence of arteriovenous crossing sign [44.6%(62/139) vs. 27.8%(419/1 509)], hard exudates [9.4%(13/139) vs. 4.9%(74/1 509)] and cotton-wool patches [19.4%(27/139) vs. 7.3%(110/1 509)] in retinal microvascular disease were significantly higher than those in control group (P<0.05 or P<0.01). The logistic regression analysis showed:age [P=0.002, odds ratio (OR)=1.06, 95%confidence interval (95%CI)=1.04-1.09], smoking (P=0.032, OR=2.17, 95%CI=2.04-2.30), retinal microvascular disease (P = 0.010, OR = 2.33, 95%CI = 0.97 - 1.27), hypertension (P < 0.001, OR = 5.21, 95%CI=4.11-6.36), diabetes mellitus (P=0.021, OR=1.03, 95%CI=1.01-1.05) and LDL-C (P=0.020, OR=2.80, 95%CI = 2.65 - 2.99) were the independent risk factors for the occurrence of ACE. Conclusions Retinal microvascular disease is the independent risk factor for the occurrence of ACE. The retinal angiography can be a useful examination to forecast ACE.

Objective To investigate the awareness rate of health knowledge,health behavior formation rate and psychological state before and after retirement intervention,analyse comprehensive psychological intervention and general psychological intervention to health behavior formation and improve the negative emotion in retired population.Methods By using cohort study method,206 retired people were randomly divided into comprehensive psychological intervention group (experimental group) and only given general psychological intervention group (control group),and each group included 103 cases.Comprehensive psychological intervention group were given health behavior and cognitive intervention,psychological intervention,psychological intervention in general family and social family care intervention,and the control group was given healthy behavior and cognitive intervention,psychological intervention.The staff were treated within 1 weeks of first assessment,2 weeks after the second assessment,4 weeks after the final.Health behavior was surveyed by Ministry of finance,the Ministry of health on public health subsidies special funds notice in city community health education pilot project in the questionnaire.Health status and quality of life were assessed with the family APGAR index (APGAR).Mental state evaluation and assessment of the treatment effect by using Hamilton Depression Scale (HAMD),MBI index method was assessed with activities of daily living.The effect of the two groups were compared before and after the intervention of health knowledge rate and formation rate of different intervention methods and psychological state of health behavior.Results The results showed that there were no significant differences between experimental group and control group in age,sex,level of education and other social,and there was no significant difference in HAMD,MBI and APGAR scores at baseline.Through the implementation of the comprehensive of psychological intervention,subjects have varying degrees of improving the awareness rate of health knowledge,and the intervention group was significantly higher than the control group (P ＜ 0.05).The two group of healthy behavior of subjects in the chopping board monitoring,physical fitness,blood pressure to separate raw and cooked on such projects had different degrees of improvement,at the same time,although no intervention,in the monitoring of blood pressure.The control group increased compared with the baseline significantly (P＜ 0.05).Intervention group had significant difference in APGAR score increased (P＜ 0.05).HAMD score and MBI score decreased and the differences were statistically significant (P＜ 0.01),while the control group had no significant difference before and after intervention.Conclusion Comprehensive psychological intervention can significantly improve the rate of formation from the awareness rate of health knowledge and health behavior of retirees,and improve the state of negative emotions from retiree.

Objective To investigate the correhtion between cognitive impairment and cerebral atherosclerosis in patients with acute ischemic stroke.Methods Acute ischemic stroke patients without cognitive impairment were recruited before symptom onset.The Montreal cognitive assessment (MoCA) was used to evaluate the cognitive function.Magnetic resonance imaging (MRI) was used to identify the infarct locations and sides.Magnetic resonance angiography,CT angiography and digital subtraction angiography were used to identify atherosclerotic arteries.Resul~ A total of 101 patients with acute ischemic stroke were enrolled,including 75 (74.3％) with cognitive impairment.The proportions of age (54.54 ± 12.59 years vs.64.43 ± 10.37 years;t =-3.960,P ＜0.001),years of education ≤6 years (50.7％ vs.11.5％;x2 =12.257,P ＜ 0.001),and cerebral atherosclerosis (89.3％ vs.50.0％;x2 =18.137,P ＜0.001) of the cognitive impairment group were significantly higher than those of the normal cognitive function group.Multivariate logistic regression analysis showed that cerebral atherosclerosis was an independent risk factor for cognitive impairment in patients with acute ischemic stroke (odds ratio 1.720,95％ confidence interval 1.005-2.942;P=0.048).MoCA score was negatively correlated with the offending vessels (r=-0.365,P＜ 0.001) and the most severe vessels of atherosclerotic degree (r=-0.243,P =0.014).Conclusions Most patients with acute ischemic stroke had cognitive impairment in the early stage after onset,and the MoCA scores was negatively correlated with the degree of cerebral atherosclerosis.Cerebral atherosclerosis was an independent risk factor for cognitive impairment in patientswith acute ischemic stroke.

Probiotics is important to promote the absorption of nutrients,to respond to immune response,to suppress inflammatory cytokines and so on.Premature infant white matter damage is the main pathological form of preterminfant brain injury,and it is often complicated with cognitive,hearing impairment,mental retardation,cerebral palsy,etc.The latest finding is that probiotics can ensure balanced nutrition intake,improve body immunity,inhibit inflammatory factor release,reduce nerve cell edema,enhance antioxidant enzyme activity and oxygen free radical scavenging,inhibit excitatory amino acid activity,reduce excitatory toxicity,and promote the recovery of function of nerve cells in white matter damage in premature infants through microbiota-gut-brain axis.This article reviews the protection and repair of probiotics in premature infants with white matter damage.

Objective:To determine the effect of hypoxic stress on glioma cell XBP1 expression, the relationship between XBP1 expres-sion and sugar metabolism, the influence of XBP1 repression on the survival rate of glioma cells under normoxia and hypoxia, and the influence of XBP1 on glioma cell glycolysis. Methods:We tested XBP1 activation in human glioma cell lines cultured under normoxia and hypoxia. XBP1 expression was repressed with siRNA technology. Cells were treated with oxidative phosphorylation inhibitor. We then detected the variation in cell apoptosis, sugar metabolism mode, and cell apoptosis and glycolysis products under normoxia and hypoxia. Results:XBP1 activation increased under hypoxia. Silencing XBP1 expression reduced glioma cell survival level, ATP and lactic acid production, and glucose consumption under hypoxia. After inhibiting cell oxidative phosphorylation, XBP1 repression significantly reduced the survival level of glioma cells. Conclusion:Hypoxia can activate XBP1 in glioma cells. Under hypoxia, XBP1 silencing de-presses cell activity and glycolysis. Glycolysis of glioma cells under hypoxia depends on XBP1 activation.

Objective To study the association between impaired fasting glucose (IFG) and cognitive impairment in community elderly residents.Methods A total of ≥60 years old 1223 people were divided into normal fasting glucose (NFG) group (n=981) and IFG group (n=242).Their baseline data were recorded,their cognitive function was assessed according to the MMSE score.Results The education level,BMI,serum FBG,TG,LDL-C levels,incidence of hypertension and hyperlipidemia were significantly higher while the serum HDL-C level was significantly lower in IFG group than in NFG group (P＜0.05,P＜0.01).The incidence of cognitive impairment was significantly higher while the score of MMSE,orientation,attention and calculation,immediate recall and language was significantly lower in IFG group than in NFG group (40.50％ vs 21.51％,24.76±5.38 vs 26.60±4.26,9.07±1.81 vs 9.48±1.15,3.39±2.00 vs 3.88±1.81,2.93±0.41 vs 2.98±0.24,6.74±1.51 vs 7.18±1.15,P＜0.01).Age,female sex,LDL-C and IFG were risk factors for cognitive impairment in the elderly (P＜0.01,P＜0.05) while the education level was a protective factor for cognitive impairment in the elderly (P=0.000).Conclusion IFG is an independent risk factor for cognitive impairment in the elderly.Early diagnosis and intervention can improve cognitive function in the elderly.

Objective To study the mutation of FLCN gene in Chinese patients with sporadic and familial primary spontaneous pneumothorax. Methods A complete genetic analysis of FLCN by use of SSCP-PCR was performed in 102 unrelated Chinese patients with isolated PSP. Results Three novel mutations (c. 924_926del, c. 1611_1631del and c. 1740C.T) and a previously reported mutation (c. 1733insC) were identified in five familial and five sporadic PSP patients. Of the 21 family members of patients with PSP including 3 previous considered as sporadic, 4 ( 19% ) had history of at least one episode of PSP and 9 (43% ) were FLCN mutant carriers without PSP. Seven of the nine (78% ) mutant carriers had pulmonary cysts detected by high-resolution computed tomography ( HRCT) . Although c. 924_926del and c. 1611 _1631 del were found in eight patients from the same geographic district, haplotype analysis demonstrated that they did not share the same affected haplotype,thus excluding common ancestry. Conclusion This study first demonstrates that FLCN mutation contributes to not only familial but also apparently sporadic' patients with isolated PSP. It suggests that mutation analysis and HRCT scan may be recommended for first-degree family members of PSP patients with FLCN mutations, irrespective of their family history status of PSP.

Background::Limited information exists regarding the impact of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection on psoriasis patients. The objective of this study was to identify clinical factors associated with the prognosis of psoriasis following SARS-CoV-2 infection.Methods::A retrospective, multicenter study was conducted between March and May 2023. Univariable and multivariable logistic regression analyses were employed to identify factors associated with coronavirus disease 2019 (COVID-19)-related psoriasis outcomes. The study included 2371 psoriasis patients from 12 clinical centers, with 2049 of them having been infected with SARS-CoV-2.Results::Among the infected groups, lower exacerbation rates were observed in individuals treated with biologics compared to those receiving traditional systemic or nonsystemic treatments (22.3% [236/1058] vs. 39.8% [92/231] vs. 37.5% [140/373], P <0.001). Psoriasis progression with lesions (adjusted odds ratio [OR] = 8.197, 95% confidence interval [95% CI] = 5.685–11.820, compared to no lesions), hypertension (adjusted OR = 1.582, 95% CI = 1.068–2.343), traditional systemic (adjusted OR = 1.887, 95% CI= 1.263–2.818), and nonsystemic treatment (adjusted OR= 1.602, 95% CI= 1.117–2.297) were found to be associated with exacerbation of psoriasis after SARS-CoV-2 infection, but not biologics (adjusted OR = 0.931, 95% CI = 0.680–1.274, compared to no treatment), according to multivariable logistic regression analysis. Conclusions::A reduced risk of psoriasis exacerbation after SARS-CoV-2 infection was observed with biologics compared to traditional systemic and nonsystemic treatments. Significant risk factors for exacerbation after infection were identified as existing psoriatic lesions and hypertension.
