Objective:To investigate the correlation between serum growth differentiation factor 11 (GDF11) level and coronary artery lesions in patients with ST-segment elevation myocardial infarction (STEMI), and the predictive efficacy of nomogram risk prediction model based on GDF11 combined with traditional risk factors on the occurrence of STEMI.Methods:This study was a retrospective cross-sectional study. Patients hospitalized in the Department of Cardiology of the 904th Hospital of Joint Logistic Support Force of People′s Liberation Army of China from 2016 to 2018 were selected and divided into control group and STEMI group. The demographic data, blood lipid level, laboratory indicators of blood and GDF11 level were collected. Logistic regression analysis screened out independent correlated factors for the occurrence of STEMI. Spearman correlation analysis clarified the correlation of each indicator with the SYNTAX or Gensini scores. A nomogram risk prediction model for the risk of STEMI occurrence and the receiver operating characteristic curve was used to compare the prediction efficiency of each model.Results:A total of 367 patients were enrolled, divided into control group ( n=172) and STEMI group ( n=195), age (66.5±11.8), male 222 (60.49%). The serum GDF11 level of STEMI group was significantly lower than that of the control group (36.20 (16.60, 70.75) μg/L vs. 85.00 (53.93, 117.10) μg/L, P<0.001). The results of multivariate logistic regression analysis showed serum GDF11( OR=0.98, 95% CI: 0.97-0.99) and traditional independent risk factors such as smoking, diabetes, C-reactive protein, homocysteine, lipoprotein (a) and apolipoprotein A1/B were independent correlate factors for the occurrence of STEMI ( P<0.05). Spearman correlation analysis showed that serum GDF11 was negatively correlated with SYNTAX score and Gensini score ( P<0.05). The nomogram model constructed by serum GDF11 combined with traditional independent risk factors (AUC=0.85, 95% CI: 0.81-0.89) had better predictive value for the occurrence of STEMI than the traditional nomogram model constructed by independent risk factors(AUC=0.80, 95% CI:0.75-0.84) or serum GDF11 (AUC=0.76, 95% CI: 0.72-0.81), all P<0.01. Conclusions:Serum GDF11 is an independent correlate factor in the occurrence of STEMI and is negatively correlated with the severity of coronary artery lesions in patients with STEMI. The nomogram model constructed based on GDF11 combined with traditional risk factors can be a good predictor for the occurrence of STEMI.

Aim To investigate the effect of discoidin domain receptor 1(DDR1)on high glucose induced endothelial cell dysfunction and the underlying mecha-nism.Methods Human umbilical vein endothelial cells(HUVECs)were cultured in vitro and divided in-to the control group and high glucose induction group(HG).HUVECs were treated with 33 mmol·L-1 D-glucose for 48 hours to construct endothelial dysfunc-tion.Pyroptosis was detected using propidium iodide staining(PI);lactate dehydrogenase(LDH)and IL-1β,IL-18 levels were determined using enzyme linked immunosorbent assay(ELISA);the expression of DDR1 and NF-κB/NLRP3 signaling pathway proteins and pyroptosis related proteinses were detected using Western blot.Subsequently,the experiment was divid-ed into the control group,HG group,HG+DDR1 NC group,and HG+DDR1 siRNA group.The effect of high glucose on the proliferation and migration of HU-VECs was observed after transfection with DDR1 siR-NA for 24 hours;ELISA was used to detect the endo-thelial nitric oxide synthase(eNOS),vascular cell ad-hesion molecule-1(VCAM-1),intercellular adhesion molecule-1(ICAM-1),as well as LDH,IL-1β,IL-18 levels;PI was employed to detect pyroptosis;Western blot was applied to detect DDR1 and NF-κB/NLRP3 signaling pathway proteins and pyroptosis related pro-teins.Results Compared with the control group,HG group decreased eNOS content,increased VCAM-1 and ICAM-1 contents,decreased cell viability and migration ability,and significantly increased the expressions of DDR1,p-NF-κB,NLRP3 and pyroptosis related pro-teins.The levels of LDH,IL-1β,IL-18 and the rate of pyroptosis significantly increased(P＜0.05).Com-pared with HG group,DDR1 siRNA could promote the secretion of eNOS,decrease the levels of VCAM-1,ICAM-1,LDH,IL-1β and IL-1 8,increase cell viability and migration ability,reduce the expression of p-NF-κB,NLRP3 and pyroptosis related proteins,and inhibit high glucose-induced pyroptosis of HUVECs(P＜0.05).Conclusions Gene silencing DDR1 can im-prove vascular endothelial cell dysfunction induced by high glucose,and the mechanism is related to the inhi-bition of NF-κB/NLRP3 signaling pathway mediated pyroptosis.

Objective To investigate the impact of total parathyroidectomy with autotransplantation (tPTx+AT)on bone mineral density and serum soluble Klotho (sKlotho)level in patients with secondary hyperparathyroidism (SHPT).Methods A total of 86 patients undergoing tPTx+AT in the Second Affiliated Hospital of Anhui Medical University from June 2019 to May 2022 were recruited in this study.Their demographic characteristics were collected before surgery,along with serum levels of corrected calcium,phosphorus,intact parathyroid hormone (iPTH),alkaline phosphatase (ALP),fibroblast growth factor 23 (FGF23),and sKlotho before and at 5 d,and 1,3,6,12 and 24 months after surgery.Dual energy X-ray absorptiometry was used to determine the BMD values of the lumbar spine L1-L4 before surgery and at 3,6,12 and 24 months after surgery.The changes in BMD and serum FGF23 and sKlotho levels before and after tPTx+AT were observed.Results Surgical treatment was successfully completed in all 86 patients,with their clinical symptoms such as bone pain and skin itching significantly improved postoperatively,and markedly decreased serum calcium,phosphorus,iPTH,ALP and FGF23 levels.The sKlotho level was significantly lower at 5 d postoperatively than that preoperatively,with that at 1 month after surgery increased by approximately 24.5％ than the preoperative level,and then the level was in a stable trend.The BMD values at the lumbar spine L1-L4 were increased postoperatively,and reached the highest levels at 12 months postoperatively.Further analyses showed that dialysis vintage,duration of SHPT,and ALP,iPTH and FGF23 levels were negatively correlated with the Z-scores of the lumbar spine L1-L4,while sKlotho level was positively correlated with the Z-scores.Conclusion tPTx+Atcan significantly improve the clinical symptoms of SHPT patients,regulate the balance of calcium and phosphorus metabolism,increase sKlotho level and reduce FGF23 level.It is an effective method to improve BMD.

Objective To understand the present situation of the standardization of separate serving chopsticks and ladles provided by catering service providers in Shanghai,and to analyze the influencing factors.Methods A total of 971 catering service providers from extra large,medium and small restaurant in 16 administrative districts of Shanghai were investigated with a self-designed questionnaire using stratified two-stage sampling method between Sep and Nov 2023,mainly concentrate on thesituation and reasons of providing separate serving chopsticks and ladles and their compliance with standards.Logistic regression was used to explore the influencing factors.Results Among the 971 units surveyed,there were 911 catering service(93.8%)providers that provided separate serving chopsticks and ladles.The main reason for providing separate serving chopsticks and ladles is for improving high quality of catering service.Binary Logistic analysis showed that catering service providers with large scale restaurant(large:OR=2.08,95%CI:2.03-2.12;medium:OR=1.99,95%CI:1.96-2.02),good quantitative level of food safety(OR=1.84,95%CI:1.83-1.85),named Shanghai Green Restaurant(OR=1.11,95%CI:1.09-1.12),known as time-honored brand(OR=1.20,95%CI:1.17-1.22),regularly acceptance of law enforcement inspections(OR=6.99,95%CI:6.91-7.07),knowledge of relevant regulation(OR=5.77,95%CI:5.70-5.85)and more channels for understanding standards(OR=1.23,95%CI:1.21-1.25)were more likely to provide separate serving chopsticks and ladles.The situation that strictly follow the fully standard requirements of separate serving chopsticks and ladles to provide 8 types of catering conducts was unsatisfactory(14.1%).Logistic analysis showed that catering service providers with large scale restaurant(extra large:OR=6.42,95%CI:2.52-16.33;large:OR=4.29,95%CI:2.24-8.21;medium:OR=3.21,95%CI:1.76-5.87)and the provision of separate serving chopsticks and ladles for more than 3 years(OR=3.1,95%CI:1.09-9.02)had a higher percentage of providing separate serving chopsticks and ladles in accordance with specification.Conclusion The overall provision of separate serving chopsticks and ladles by catering service providers in Shanghai is satisfactory.The scale of restaurant,quantitative level of food safety and named Shanghai Green Restaurant are possible main factors for providing separate serving chopsticks and ladles of catering service providers.However,the implementation is not good according to the standardization.The different scale of restaurant and the time of the provision of separate chopsticks and ladles are possible factors for providing separate serving chopsticks and ladles in accordance with specification.

AIM To analyze the constituents absorbed into blood and brain from Zhishe Tongluo Capsules.METHODS Sixteen rats were randomly assigned into four groups and given intragastric administration(3.1 g/kg),after which the cerebral ischemia-reperfusion injury(MACO)model was established,the blood and brain tissues were collected,and UHPLC-Q Exactive Focus MS/MS was adopted in the identification of prototype constituents.RESULTS Total 70 constituents were identified,20 of which were found in the blood,mainly including flavonoids,tanshinones and Ligusticum chuanxiong phthalides,and 7 of them could enter the brain through blood-brain barrier.Compared with the normal administration group,the MACO administration group demonstrated added constituents absorbed into blood containing 3-hydroxybenzoic acid,calycosin-7-glucoside,curcumenol,senkyunolide B,dihydrotanshinone I and cryptotanshinone;removed constituents absorbed into brain containing puerarin,elemicin,sedanolide,and added those containing salvianolic acid A,senkyunolide I,dihydrotanshinone I in the left brain tissues(infarcted side).CONCLUSION The constituents absorbed into blood and brain from Zhishe Tongluo Capsules,along with the enhanced absorptions of phthalides,quinones and phenols in MACO rats in vivo may be the active substances for treating cerebral infarction.
