Objective To explore the influencing factors of coronary artery lesion severity in patients with acute coronary syndrome (ACS). Methods Clinical data of ACS patients admitted to Zhongshan Hospital, Fudan University from December 2017 to December 2019 were consecutively collected. The modified Gensini score was used to assess the severity of coronary artery lesions. Univariate and multivariate linear regression analyses were performed to identify independent factors associated with coronary artery lesion severity. Results A total of 1 689 ACS patients were included, with an average age of (64.04±11.45) years; 1 353 (80.11%) were male, and the mean modified Gensini score was (8.12±4.03). Multivariate linear regression analysis revealed that sex (β＝0.97, P＝0.001), age (β＝0.03, P＝0.021), estimated glomerular filtration rate (eGFR; β＝－0.03, P＜0.001), low-density lipoprotein cholesterol (LDL-C; β＝0.58, P＜0.001), apolipoprotein A1 (Apo A1; β＝－1.28, P＝0.012), lipoprotein(a) [Lp(a); β＝0.001, P＝0.033], and glycated hemoglobin A_1C (HbA_1C; β＝0.45, P＜0.001) were independent influencing factors of the modified Gensini score. Conclusions Metabolic indicators, including Apo A1, LDL-C, HbA_1C, and Lp(a), may serve as risk factors for coronary artery lesion severity in ACS patients, with Apo A1 demonstrating the strongest impact.

OBJECTIVE: To review the clinical characteristics of patients with traumatic spinopelvic dissociation (SPD) and explore the diagnostic and therapeutic methods. METHODS: A clinical data of 22 patients with SPD who underwent surgical treatment between March 2019 and August 2024 was retrospectively analyzed. There were 13 males and 9 females, with an average age of 35.5 years (range, 14-61 years). The causes of injury included falling from height in 16 cases, traffic accidents in 5 cases, and compression injury in 1 case. Sacral fractures were classified based on morphology into "U" type (9 cases), "H" type (7 cases), "T" type (4 cases), and "λ" type (2 cases). According to the Roy-Camille classification, there were 4 cases of type Ⅰ, 12 cases of type Ⅱ, 2 cases of type Ⅲ, and 4 cases of type Ⅳ. The Cobb angle was (35.7± 22.0)°. Sixteen patients were accompanied by lumbosacral trunk and cauda equina nerve injury, which was classified as grade Ⅱ in 5 cases, grade Ⅲ in 5 cases, and grade Ⅳ in 6 cases according to the Gibbons grading. The time from injury to operation was 2-17 days (mean, 5.7 days). Based on the type of sacral fracture and sacral nerve injury, 6 cases were treated with closed reduction and minimally invasive percutaneous sacroiliac screw fixation, 16 cases were treated with open reduction and lumbar iliac fixation (8 cases)/triangular fixation (8 cases). Among them, 11 patients with severe fracture displacement and kyphotic deformity leading to sacral canal stenosis or bony impingement within the sacral foramen underwent laminectomy and sacral nerve decompression. X-ray films and CT were reviewed during followed-up. The Matta score was used to evaluate the quality of fracture reduction. At last follow-up, the Majeed score was used to assess the functional recovery, and the Gibbons grading was used to evaluate the nerve function. RESULTS: All operations were successfully completed. All patients were followed up 8-64 months (mean, 20.4 months). Two patients developed deep vein thrombosis of the lower limbs, 2 had incision infections, and 1 developed a sacral pressure ulcer; no other complications occurred. Radiological examination showed that the Cobb angle was (12.0±6.8)°, which was significantly different from the preoperative one ( t=6.000, P<0.001). The Cobb angle in 16 patients who underwent open reduction was (14.9±5.5)°, which was significantly different from the preoperative one [(46.8±13.9)° ] ( t=8.684, P<0.001). According to the Matta scoring criteria, the quality of fracture reduction was rated as excellent in 8 cases, good in 7 cases, fair in 5 cases, and poor in 2 cases, with an excellent and good rate of 68.2%. Bone callus formation was observed at the fracture site in all patients at 12 weeks after operation, and bony union achieved in all cases at last follow-up, with a healing time ranging from 12 to 36 weeks (mean, 17.6 weeks). At last follow-up, the Majeed score was rated as excellent in 7 cases, good in 10 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 77.3%. One patient experienced a unilateral iliac screw breakage at 12 months after operation, but the fracture had already healed, and there was no loss of reduction. Among the 16 patients with preoperative sacral nerve injury, 11 cases showed improvement in nerve function (6 cases) or recovery (5 cases). CONCLUSION SPD with low incidence, multiple associated injuries, and high incidence of sacral nerve injury, requires timely decompression of the sacral canal for symptomatic sacral nerve compression, fractures reduction, deformities correction, and stable fixation.

Objective To construct a nomogram model for predicting lower extremity deep vein throm-bosis(DVT)during hospitalization in the patients undergoing mechanical thrombectomy due to acute ische-mic stroke.Methods A total of 901 patients with acute anterior circulation large vessel occlusion undergoing mechanical thrombectomy in the hospital from January 1,2017 to January 1,2024 were selected as the study subjects and divided into the lower extremity DVT group(n=112)and non-DVT group(n=789)according to whether DVT occurred after surgery.The observation indicators included the clinically relevant data,perio-perative related indicators and related laboratory indicators.The multivariate logistic regression was used to analyze the relevant influencing factors,and then the nomogram model was established.The receiver operating characteristic(ROC)curve and area under the curve(AUC)were used to analyze the predictive efficiency of the model.The clinical benefit of the predictive model was assessed by the clinical decision curve analysis(DCA)curve.Results There were statistically significant differences in the age,NIHSS score at admission,history of diabetes mellitus,history of smoking and history of DVT between the two groups(P<0.05).There were statistically significant differences in the time from onset to femoral artery puncture,time from onset to admission,time from femoral artery puncture to revascularization and postoperative complicating pul-monary infection between the two groups(P<0.05).There were statistically significant differences in D-di-mer,venous blood glucose and PLT at admission between the two groups(P<0.05).The multivariate logis-tic regression analysis results showed that the NIHSS score at admission,diabetes history,age,D-dimer,time from onset to femoral artery puncture and postoperative complicating pulmonary infection were the independ-ent influencing factors for lower extremity DVT during hospitalization in the patients with acute ischemic stroke treated with mechanical thrombectomy(P<0.05).The ROC curve and Bootstrap method verification results all showed that the nomogram predictive ability was strong.The DCA curve showed that when the threshold value was 0.12-0.96,the clinical benefit and applicability of the model were the best.Conclusion The constructed nomogram model can better predict the clinical outcome of the patients,and has a wide range of clinical applicability.

Objective To investigate the effect of allicin on the replication of hepatitis B virus(HBV)and to pre-liminarily elucidate its underlying molecular mechanisms.Methods HepG 2.2.15 cells were treated with different concentrations of allicin and the levels of HBsAg and HBeAg were assessed by ELISA.Cell viability was evaluated using the CCK-8 assay to determine the optimal concentration of allicin;HepG2-NTCP cells were incubated with the optimal concentration of allicin for 48 hours,and the expression of HBV-related markers was detected by RT-qPCR;The activity of four HBV promoters(Enh I/Xp,SP1,SP2,and CP)was analyzed using a dual-lucif-erase reporter gene experiment.The effect of allicin on promoter activity was assessed;Gene-regulation tools were used to predict potential transcription factor that might bind to the promoter.After over-expressing the transcription factor,cells were incubated with allicin and the effect on promoter activity was examined;Finally,ChIP was used to confirm whether these transcription factors bind to the HBV promoters and whether allicin treatment affects this binding.Results Allicin significantly reduced the expression of HBsAg and slightly lowered the expression of HBeAg(P＜0.001);A concentration of 40 μmol/L allicin significantly inhibited HBV DNA replication and tran-scription(P＜0.05),without affecting cell viability;Allicin also significantly suppressed the activity of the HBV promoter SP2(P＜0.001).Further investigation revealed that the transcription factor SP1 could bind to the DNA se-quence of the HBV promoter SP2,and this binding was significantly inhibited after allicin treatment(P＜0.001).Conclusions Allicin inhibits the binding of the transcription factor SP1 to HBV promoter SP2,thereby reducing the transcriptional activity of HBV and suppressing viral replication.

Objective To explore the effect of endoplasmic reticulum stress activating transcription factor 6(ATF6)on the expression of reproduction related gene heat shock protein family A member 1 like(HSPA1L)and preliminari-ly clarify its regulatory molecular mechanism.Methods The ATF6 over-expression plasmid was transfected into HEK-293T cells and the over-expression efficiency was verified by RT-qPCR and Western blot.The transcriptome sequen-cing information of testis tissue of male ATF6 knockout mice was used to screen five reproduction related genes down-stream of ATF6.The dual luciferase reporter assay selected the downstream genes with high promoter activity and de-tected the effect of over-expression of ATF6 on the promoter activity of downstream genes.The possible binding sites of ATF6 and downstream gene promoters were predicted by gene-regulation.RT-qPCR and Western blot were used to detect the effect of over-expression of ATF6 on downstream gene expression in HEK-293T cells.Whether ATF6 binds to downstream gene promoters was determined by electrophoretic mobility shift assay(EMSA).Results The expres-sion of ATF6 mRNA(P＜0.001)and protein(P＜0.001 and P＜0.05)in HEK-293T cells was significantly increased after transfection.HSPA1L(P＜0.001 and P＜0.05),a reproductive related gene downstream of ATF6 was screened by transcriptome sequencing and dual luciferase reporter assay.ATF6 promoted the truncated promoter activity of HSPA1L(P＜0.001).After over-expression of ATF6,the expression of HSPA1L was significantly increased(P＜0.001).The differences were statistically significant.ATF6 protein could bind to the aagtcgtcac DNA sequence of HSPA1L promoter.Conclusions ATF6,a key molecule of endoplasmic reticulum stress,regulates the expression of reproduction related gene HSPA1L by binding to the promoter of HSPA1L.This result will lay a foundation for further research on the prevention or treatment of endoplasmic reticulum stress(ERS)related male infertility.

Objective:To investigate the risk of new-onset stroke caused by cerebral microbleed (CMB) and asymptomatic lacunar infarction (ALI) and their risk factors.Methods:A prospective observational study over a 18 month period was conducted on 397 non stroke patients who visited the Affiliated Hospital of Xuzhou Medical University from March 2020 to June 2022. By the presence of CMB and ALI about magnetic resonance imaging, they were divided into th control group (without CMB and ALI, 117 cases, 29.5%), ALI group (101 cases, 25.4%), CMB group (89 cases, 22.4%) and CMB-ALI group (90 cases, 22.7%).They were followed up for 18 months, the risk factors for CMB, ALI, and the risk of new stroke were analyzed.Results:The systolic blood pressure and uric acid in the CMB group were higher than those in the control group: (155.2 ± 24.2) mmHg(1 mmHg = 0.133 kPa) vs. (138.2 ± 19.0) mmHg, (387.0 ± 28.3) μmol/L vs. (354.0 ± 21.5) μmol/L, there were statistical differences ( P<0.05). After followed up for 18 months, the incidence rate of cerebral infarction, cerebral hemorrhage and TIA in the CMB group and CMB-ALI group were higher than those in the control group: 13.5%(12/89), 13.3%(12/90) vs.5.1%(6/117); 9.0%(8/89), 10.0%(9/90) vs. 2.6%(3/117); 5.6%(5/89), 6.7%(6/90) vs. 0.8%(1/117), there were statistical differences ( P<0.05). Conclusions:CMB is prone to abnormal systolic blood pressure and uric acid. CMB, CMB-ALI are prone to new onset ischemic stroke, cerebral hemorrhage and TIA.

Atherosclerosis(AS)is a chronic inflammatory disease of large and medium-sized arteries that leads to ischemic heart disease,stroke,and peripheral vascular disease.Despite the current treatments,mortality and disability still remain high.Sonodynamic therapy(SDT),a non-invasive and localized methodology,has been developed as a promising new treatment for inhibiting atherosclerotic progression and sta-bilizing plaques.Promising progress has been made through cell and animal assays,as well as clinical trials.For example,the effect of SDT on apoptosis and autophagy of cells in AS,especially macrophages,and the concept of non-lethal SDT has also been proposed.In this review,we summarize the ultrasonic parameters and known sonosensitizers utilized in SDT for AS;we elaborate on SDTs therapeutic effects and mechanisms in terms of macrophages,T lymphocytes,neovascularization,smooth muscle cells,lipid,extracellular matrix and efferocytosis within plaques;additionally,we discuss the safety of SDT.A comprehensive summary of the confirmed effects of SDT on AS is conducted to establish a framework for future researchers.

Objective:To investigate the correlation of serum high-sensitivity cardiac troponin T (hs-cTnT) level with major adverse cardiovascular events (MACE) in patients with chronic coronary syndrome (CCS) undergoing percutaneous coronary intervention (PCI) and to explore its predictive value.Methods:It was a case-control study. Clinical data of 731 patients with CCS who underwent PCI in the Affiliated Zhongshan Hospital of Fudan University between May 2019 and April 2020 were retrospectively analyzed. Baseline clinical characteristics and pre/postoperative laboratory results were gathered, and patients were followed up and the incidence of MACE was documented. The correlation of serum hs-cTnT levels with MACE was analyzed, and the threshold of hs-cTnT for predicting the occurrence of MACE was determined.Results:Among 731 patients there were 560 males (76.61%) with the age of (64.05±9.48) years. Patients were followed up for 29.9 (18.8, 35.3) months, and MACE occurred in 216 cases (MACE group), and did not occur in 515 cases (control group). The X-tile software analysis showed that the optimal cutoff value of post-PCI hs-cTnT was 4.17×upper reference limit (URL) for predicting MACE ( P=0.033). Multivariate Cox regression analysis revealed that postoperative cTnT>6×URL was an independent risk factor for MACE in CCS patients after PCI ( HR=1.87, 95% CI: 1.19-2.94, P=0.007). The net reclassification index pairwise comparison results indicated that hs-cTnT>6×URL had the better predictive performance for MACE in CCS patients after PCI compared to 7×URL, 8×URL, 9×URL, 10×URL and 15×URL (all P<0.05). Conclusion:Postoperative hs-cTnT>6×URL is an independent risk factor for MACE in CCS patients after PCI, and hs-cTnT>6×URL is the optimal threshold for predicting the risk of MACE.

Objective:To analyze the risk factors of three-vessel disease (TVD) in patients with stable coronary artery disease (SCAD).Methods:The clinical data of 447 patients with SCAD diagnosed in Zhongshan Hospital from May 2019 to April 2020 were retrospectively analyzed, including 108 cases with the single-vessel disease (SVD), 136 cases with the two-vessel disease, and 203 cases with three-vessel disease. The general data and hematological indexes were compared between patients with SVD and those with TVD; the related factors for TVD in SCAD patients were analyzed with univariate and multivariate logistic regression.Results:There were 244 males (78.5%) and 67 females (21.5%) with a median age of 57 years (64, 69). Univariate analysis showed that there were significant differences in diabetes history ( χ2=7.75, P=0.005), uric acid ( Z=-2.10, P=0.036), glycosylated hemoglobin ( Z=-2.77, P=0.006) and high density lipoprotein cholesterol (HDL-C) ( Z=-2.99, P=0.003) levels between SVD and TVD groups. Multivariate analysis showed that the high level of blood uric acid ( OR=1.01, 95% CI: 1.00-1.01, P<0.05) and the low level of HDL-C ( OR=3.29, 95% CI:1.23-8.85, P<0.05) were related risk factors of TVD. Conclusion:High blood uric acid level and low HDL-C level are related factors for TVD in patients with SCAD.

Objective: To investigate the function and mechanism of golgi protein 73(GP73) neutralizing antibody in Methionine-choline deficient(MCD) diet-induced non-alcoholic fatty liver disease(NAFLD). Methods : Total cholesterol(TC),aspartate aminotransferase(AST),triglyceride(TG) and serum alanine aminotransferase(ALT) levels were detected after MCD diet and GP73 neutralizing antibody intervention. Lipid deposition in liver tissue was observed by oil red O staining; qRT-PCR was used to detect the gene expression ofACC1,HMGR,TIMP1andTGF-βin liver tissue; Western blotting was used to detect α-SMA and SREBP1 protein expression levels in liver tissues. Results : GP73 neutralizing antibody could reduce the accumulation of serum ALT and AST(P<0.001) induced by MCD diet, and increase the levels of serum TG and TC(P<0.001);The gene expression levels ofHGMR(P<0.001),TGF-β(P<0.05),ACC1(P<0.01) and the protein expression levels of α-SMA(P<0.05) and SREBP1(P<0.05) in liver tissue significantly decreased, and the lipid deposition was also improved. Conclusion GP73 neutralizing antibody inhibits the formation of MCD-induced NAFLD by slowing down the progression of liver fibrosis and reducing the deposition of liver lipids.
