Objective To explore the clinical effect of Jieyu Anshen decoction combined with aripiprazole tablet in the treatment of chronic schizophrenia. Methods A total of 210 patients with chronic schizophrenia who were treated in our hospital from March 2015 to March 2017 were randomly divided into two groups,with 105 cases in each group. The control group was treated with aripiprazole tablet. The observation group was treated with Jieyu Anshen decoction combined with aripiprazole tablet. The treatment effect was observed and compared. Results There was no significant difference in the clinical condition between the two groups before treatment, and the improvement was more obvious in the observation group after treatment; The effective rate in the observation group (90.47％) was significantly higher than in the control group (80.0％), the difference was statistically significant (P<0.05). There was no significant difference in the safety of the two groups. Conclusion Jieyu Anshen Decoction combined with aripiprazole tablets in the treatment of chronic schizophrenia compared to conventional methods, can improve clinical efficacy, but also has good safety, it is worth clinical reference.

OBJECTIVETo explore the protein expression of heme oxygenase-1 (HO-1) and platelet endothelial cell adhesion molecules-1 (PECAM-1) in human coronary artery endothelial cells induced with Zinc Oxide Nanoparticle (ZnO-NPs).

METHODSMTT assay was used to determine the cell viability of ZnO-NPs. Levels of HO-1 and PECAM-1 protein in culture supernatants were measured using ELISA after human coronary artery endothelial cells were treated with different concentrations (0, 10, 20, 40µg/ml) of ZnO-NPs for 24 h.

RESULTSThe cell viability of human coronary artery endothelial cells in each group was 89.76%, 83.61%, 63.10%, 53.20%, 48.11%, 42.35%, 38.06%, 25.44% respectively when treated with different concentrations of ZnO-NPs (12.5, 25, 50, 70, 80, 90, 100, 200µg/ml). Protein levels of HO-1 (ng/L) in each group were 0.041±0.011, 0.512±0.076, 0.906±0.059, 1.062±0.089 respectively after the stimulation of different concentrations of ZnO-NPs (0, 10, 20, 40µg/ml). Comparisons in each group were statistically significant (P < 0.05). Protein levels of PECAM-1 (µg/L) in each group were 7.966 ± 0.046, 7.993 ± 0.036, 8.629 ± 0.052, 8.811 ± 0.039 respectively after the stimulation of different concentrations of ZnO-NPs (0, 10, 20, 40 µg/ml). Compared with the control group, protein levels of PECAM-1 increased (P < 0.05) when the concentration of ZnO-NPs was 20µg/ml or 40 µg/ml.

CONCLUSIONZnO-NPs stimulation could inhibit the viability of human coronary artery endothelial cells and upregulate the protein expression of HO-1 and PECAM-1.

Objective:To discuss the association between occupational acid fog exposure and accelerated biological aging of the workers,and to clarify its related risk factors.Methods:A total of 341 male workers exposed to occupational acid fog and 201 male workers without occupational exposure were selected as the study subjects,and they were divided into exposure group and control group,respectively.The general informations of the subjects in two groups were collected through questionnaires and physical examinations.The levels of red blood cell count(RBC),platelet count(PLT),albumin(ALB),urea(Urea),creatinine(CR),triglycerides(TG),total cholesterol(TC),glycated hemoglobin(HBA1c),and high-sensitivity C-reactive protein(Hs-CRP)in serum of the subjects in two groups were detected.The Klemera-Doubal method(KDM)was used to construct the composite aging measure,KDM-biological age(BA)(KDM-BA).The model parameters were trained using samples from the 2009 China Health and Nutrition Survey(CHNS)Database to calculate the BA acceleration of the subjects in two groups;stratified analysis based on the population characteristics was conducted to analyze the BA of the subjects in two groups with different population characteristics;generalized linear model was used to analyze the factors influencing BA acceleration due to acid fog exposure.Results:The model parameters were trained using samples from the 2009 CHNS Database,including 8 133 cases aged 20-79 years,of which 3 788 were male.The levels of Urea,CR,HBA1c,ALB,and TC,as well as systolic blood pressure(SBP),total working years,sleep duration,and body mass index(BMI)of the subjects between two groups had significant differences(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05).In entire population and exposure group,the BA acceleration in the smokers was significantly higher than that in the non-smokers(P<0.05).In entire population,control group,and exposure group,the BA accelerations of the subjects in different BMI groups were significantly decreased with the increase of BMI(P<0.05).Compared with control group,the BA acceleration of the subjects in exposure group was significantly increased(P<0.05),including those under 40 years old,with total working years of 4-7 years,Han nationality,unmarried,smokers,and sleep duration 6-7 h,and with overweight.Acid fog exposure,smoking,and BMI were associated with the BA acceleration(β=0.72,95%CI:0.24-1.21;β=0.59,95%CI:0.11-1.06;β=-0.29,95%CI:-0.35—-0.22).Conclusion:Occupational acid fog exposure may accelerate the biological aging in the workers,and acid fog is a risk factor to accelerate the biological aging of the body.

Objective:To evaluate the role of stimulator of interferon genes (STING) signaling pathway in carbon monoxide (CO)-releasing molecule-3 (CORM-3)-induced reduction of hepatocyte pyroptosis and apoptosis in a rat model of hepatic ischemia-reperfusion.Methods:Forty-eight clean-grade healthy male Sprague-Dawley rats, aged 9-11 weeks, weighing 320-380 g, were divided into 4 groups ( n=12 each) using a random number table method: sham operation group (S group), ischemia-reperfusion group (IR group), CORM-3 group (C group) and STING agonist ADU-S100 group (A group).Hepatic ischemia-reperfusion injury models were developed by reversible ligation of left middle hepatic artery, portal vein and bile duct branches for 45 min, followed by reperfusion in anesthetized animals in IR, C and A groups.In group C, CORM-3 4 mg/kg was injected into the femoral vein immediately after reperfusion.The equal volume of normal saline containing dimethyl sulfoxide was injected into the femoral vein in S, IR and A groups.At 1.5 h after injection into the femoral vein, ADU-S100 10 mg/kg was intraperitoneally injected in A group, and the equal volume of normal saline was given instead in S, IR and C groups.The serum alanine transaminase (ALT) and aspartate transaminase (AST) concentrations were determined at 3 h of reperfusion.The rats were sacrificed at 12 h of reperfusion, and liver tissues were collected for determination of the content of CO (by colorimetry), expression of interleukin-1beta (IL-1β), IL-18, Bcl-2, Bax, interferon regulatory factor 3 (IRF3), phosphorylated IRF3 (p-IRF3), STING, NOD-like receptor protein 3 (NLRP3), aspirin D (GSDMD) and activated caspase-1 (by Western blot), and pyroptosis and apoptosis rates of hepatocytes (by immunofluorescence staining).The liver injury was scored. Results:Compared with group S, the serum ALT and AST concentrations, liver injury score, CO content, and pyroptosis and apoptosis rates of hepatocytes were significantly increased, and the expression of IL-1β, IL-18, p-IRF3, STING, NLRP3, GSDMD and activated caspase-1 was up-regulated, and the Bcl-2/Bax ratio was decreased in group IR ( P<0.05).Compared with group IR, the serum ALT and AST concentrations, liver injury score, and pyroptosis and apoptosis rates of hepatocytes were significantly decreased, the CO content was increased, the expression of IL-1β, IL-18, p-IRF3, STING, NLRP3, GSDMD and activated caspase-1 was down-regulated, and the Bcl-2/Bax ratio was increased in group C ( P<0.05).Compared with group C, the serum ALT and AST concentrations, liver injury score, and pyroptosis and apoptosis rates of hepatocytes were significantly increased, the CO content was decreased, the expression of IL-1β, IL-18, p-IRF3, STING, NLRP3, GSDMD and activated caspase-1 was up-regulated, and the Bcl-2/Bax ratio was decreased in group A ( P<0.05). Conclusions:The mechanism by which CORM-3 attenuates hepatocyte pyroptosis and apoptosis may be related to the inhibition of activation of STING signaling pathway in a rat model of hepatic ischemia-reperfusion.
