Objective To investigate the value of preoperative clinical data and computed tomography angiography (CTA) data in predicting perioperative mortality risk in patients with acute aortic dissection (AAD), and to construct a Nomogram prediction model. Methods A retrospective study was conducted on AAD patients treated at Affiliated Hospital of Zunyi Medical University from February 2013 to July 2023. Patients who died during the perioperative period were included in the death group, and those who improved during the same period were randomly selected as the non-death group using a random number table method. The first CTA data and preoperative clinical data within the perioperative period of the two groups were collected, and related risk factors were analyzed to screen out independent predictive factors for perioperative death. The Nomogram prediction model for perioperative mortality risk in AAD patients was constructed using the screened independent predictive factors, and the effect of the Nomogram was evaluated by calibration curves and area under the curve (AUC). Results A total of 270 AAD patients were included. There were 60 patients in the death group, including 42 males and 18 females with an average age of (56.89±13.42) years. There were 210 patients in the non-death group, including 163 males and 47 females with an average age of (56.15±13.77) years. Multivariate logistic regression analysis showed that type A AAD [OR=4.589, 95%CI (2.273, 9.267), P<0.001], irregular tear morphology [OR=2.054, 95%CI (1.025, 4.117), P=0.042], decreased hemoglobin [OR=0.983, 95%CI (0.971, 0.995), P=0.007], increased uric acid [OR=1.003, 95%CI (1.001, 1.005), P=0.004], and increased aspartate aminotransferase [OR=1.003, 95%CI (1.000, 1.006), P=0.035] were independent risk factors for perioperative death in AAD patients. The Nomogram prediction model constructed using the above risk factors had an AUC of 0.790 for predicting perioperative death, indicating good predictive performance. Conclusion Type A AAD, irregular tear morphology, decreased hemoglobin, increased uric acid, and increased aspartate aminotransferase are independent predictive factors for perioperative death in AAD patients. The Nomogram prediction model constructed using these factors can help assess the perioperative mortality risk of AAD patients.

Objective To construct and evaluate a prognostic model for clear cell renal cell carcinoma(ccRCC)based on preoperative lipid ratios, cM0(i+)staging, and other clinical characteristics, so as to provide a precise tool for clinical prognosis assessment. Methods A retrospective analysis was conducted on the clinical data of 215 ccRCC patients treated in our hospital during May 2014 and May 2023. Lipid ratios were calculated using preoperative lipid data, and patients were divided into cM0(i+)stage or cM0 stage according to postoperative circulating tumor cells(CTCs)test results. The optimal lipid ratio and cutoff value were selected using receiver operating characteristic(ROC)curves and the X-tile method. Patients were subdivided into three groups based on the level of the low-density lipoprotein cholesterol to non-low-density lipoprotein cholesterol ratio(LNLR)and cM0(i+)staging:Group A [LNLR>1.68 and diagnosed with cM0(i+)], Group B [LNLR>1.68 or diagnosed with cM0(i+)], and Group C(LNLR ≤1.68 and diagnosed with cM0). Kaplan-Meier survival analysis was used to plot survival curves for patients in different groups. The log-rank test was employed to compare differences in recurrence-free survival(RFS)among the subgroups. Multivariate Cox regression analysis was conducted to identify the independent risk factors influencing RFS, and a nomogram prediction model was constructed based on these results. The predictive performance of the model was validated using ROC curves, calibration curves, and decision curves. Results ROC curves were plotted for lipid markers, and LNLR was identified as the most predictive for RFS. Its optimal cutoff point was 1. 68. Patients in Group A experienced a significantly shorter postoperative RFS. Multivariate Cox regression analysis identified preoperative LNLR, cM0(i+)staging, pathological grade, and stage as independent risk factors for RFS. A nomogram model was constructed based on these risk factors. The area under the ROC curve(AUC)for 1-, 3-, and 5-year RFS was 0.896(95% CI:0.8121-0.9627), 0.890(95%CI:0.7879-0.9641), and 0.870(95%CI:0.7697-0.9526), indicating good discriminatory ability and predictive performance. Calibration plots demonstrated good agreement between predicted and actual outcomes. Clinical decision curve analysis showed high clinical net benefit. Conclusion Preoperative LNLR level is an independent risk factor for RFS in ccRCC patients. The prognostic prediction model based on LNLR, cM0(i+)staging, patient pathological grade, and staging demonstrates good predictive performance for RFS and holds potential clinical application value.

Objective:To explore the clinical application of mobile-intelligent medical management system for gout patients.Methods:This study was a randomized controlled trial. One hundred and two patients with gout who visited rheumatology department of the First Hospital of Jilin University from January 2022 to October 2023 were randomly divided into study group ( n=53) and the control group ( n=49). Patients in the study group were managed by the mobil-gout(M-G) health management system which consists of a distant management plateform and an App. The body weight and blood uric acid levels were regularly self-tested by patients, and the information was sent to the system, the doctor gave feed-back advice on medication adjustment and dietary management every 2 weeks. While patients in the control group were managed following the conventional outpatient consultation mode. The serum uric acid levels, liver and kidney function tests and physical examinations were conducted on the day of enrollment and 3 and 6 months after treatment. The number of affected joints and the frequency of attacks were evaluated, and pain was assessed using the visual analog scale (VAS). The efficacy of treatment were compared between two groups. Results:After 3 and 6 months of treatment, the serum uric acid levels in study group were significantly lower than those in control group (408.0 (345.0, 450.0)μmol/L vs. 458.0 (409.0, 482.0)μmol/L, 371.0 (338.5, 409.0) μmol/L vs. 412.0 (368.5, 445.0)μmol/L; Z=3.37, 4.61, P<0.01); and VAS scores were also significantly lower than those in control group (6.66±1.46 vs. 4.68±1.80, 7.45±1.06 vs. 5.88±1.52; t=14.12, 13.72, P<0.01). After 6 months of treatment, the frequency of gout attacks in the study group was significantly lower than that in the control group ( χ2=9.30, P<0.05). As the follow-up period was extended, the average number of joints affected by gout attacks and the frequency of gout attacks in the study group showed a reducing trend compared to the control group, but the differences were not statistically significant ( P>0.05). Conclusions:The M-G medical management system can more effectively control uric acid levels and alleviate symptome for gout patients.

Objective To report a case of tibial synovial sarcoma and review relevant literature to enhance understanding of this disease.Methods The clinical data of a patient with tibial synovial sarcoma treated at Kaifeng Central Hospital were retrospectively analyzed.A literature search was conducted in domestic and international databases,including China National Knowledge Infrastructure(CNKI),Wanfang Data,PubMed,Web of Science,and Embase,up to July 2024.Relevant literature was comprehensively reviewed to summarize the imaging and pathological characteristics,treatment,and prognosis of synovial sarcoma.Results A 29-year-old female patient was admitted with left lower extremity pain.X-ray examination revealed a proximal tibia space-occupying lesion suggestive of malignancy,and a mid-tibial space-occupying lesion considered benign.Contrast-enhanced computed tomography(CT)and plain magnetic resonance imaging(MRI)of the proximal tibial lesion also suggested malignancy.Ultrasound-guided biopsy of the proximal tibial tumor revealed a poorly differentiated malignant tumor.Immunohistochemistry results indicated monophasic synovial sarcoma,requiring genetic testing for definitive diagnosis.The patient underwent wide resection of the proximal left tibial malignancy with tumor-type artificial joint replacement,combined with curettage and bone cement filling for the left mid-tibial lesion under anesthesia.Postoperative pathology of space-occupying lesions in the proximal tibia confirmed monophasic synovial sarcoma,and fluorescence in situ hybridization(FISH)demonstrated a rupture of the synovial sarcoma translocation gene(SYT)(i.e.,SS18 positive).There was no recurrence or metastasis found in the patient during the reexamination 6 months after postoperative chemotherapy.As of July 2024,15 cases of genetically confirmed primary intraosseous synovial sarcoma have been reported internationally.Symptoms included pain and swelling,with a medical history of 1-2 years.The X-ray and CT findings showed osteolytic destruction with bone cortical discontinuity.In 13 cases,the intraosseous masses extended to the extraosseous area;in 2 cases,punctate calcifications were detected within the masses.Plain MRI scan showed iso-signal or hypo-signal on T1WI and hyper-signal,iso-signal,and hypo-signal on fat-suppressed T2WI,and enhanced MRI scan demonstrated heterogeneous enhancement.Pathological examination showed spindle-shaped cells under microscopy.Immunohistochemistry results showed positive epithelial membrane antigen(EMA),broad-spectrum cytokeratin(AE1/AE3),Ewing's sarcoma marker(CD99),and transducin-like enhancer of Split 1(TLE1).Twelve patients underwent surgical treatment;6 patients received adjuvant chemotherapy after surgery,of whom 4 developed local recurrence or distant metastasis at initial diagnosis,and 3 died during follow-up.Among the 6 patients who did not receive adjuvant chemotherapy,3 suffered from recurrence or distant metastasis.Conclusions Primary intraosseous synovial sarcoma is a rare malignant tumor with non-specific clinical manifestations.Imaging features typically include osteolytic destruction and intraosseous masses extending extraosseously,suggesting an intraosseous origin.Pathology and immunohistochemistry aid diagnosis,but definitive confirmation relies on further genetic testing.At present,the main treatment regimens for synovial sarcoma involve comprehensive therapies such as surgery and adjuvant chemotherapy,and the prognosis of patients is poor.

Aim To investigate the effect of curcumol(Cur)on apoptosis in senescent Hep3B cells induced by XL413.Methods XL413 induced a senescence model in Hep3B cells.Cur intervention was adminis-tered.CCK-8 and Incucyte? assays were used to eval-uate cell proliferation.Senescence-associated beta-gal-actosidase(SA-β-gal)staining was performed to assess cellular senescence.Flow cytometry was employed to detect apoptosis.RT-qPCR was conducted to measure the mRNA expression levels of senescence-associated secretory phenotype(SASP)factors IL-6,IL-8,and CXCL10.Western blot was performed to assess the ex-pression levels of p16,PI3K,p-PI3K,Akt,p-AKT,Bax,and Bcl-2.The ratios of p-PI3K/PI3K,p-Akt/Akt,and Bcl-2/Bax were calculated.Results Fol-lowing XL413 intervention,the proportion of SA-β-gal-positive cells and the expression of p16 protein signifi-cantly increased compared to the control group(P<0.05),suggesting the successful establishment of the cell senescence model.CCK-8 assay showed that the IC50 values of Cur intervention in Hep3B cells at 24 h,48 h,and 72 h were 106.40 μmol·L-1,54.67 μmol·L-1,and 31.87 μmol·L-1,respectively.Incucy-te? cell proliferation assay demonstrated that the cell proliferation rate was significantly lower in the XL413 group compared to that in the control group(P<0.05),and further decreased after Cur intervention(P<0.05)in a concentration-dependent manner.The proportion of apoptotic cells in the Cur group was sig-nificantly higher than that in the XL413 group(P<0.05),also exhibiting concentration dependence.Cur intervention led to a significant reduction in IL-6,IL-8,CXCL10 mRNA expression levels,as well as p-PI3K/PI3K and p-AKT/AKT ratios compared to the XL413 group(P<0.05),with a concentration-de-pendent effect.The expression of Bax protein increased(P<0.05),while Bcl-2 protein expression decreased and the Bcl-2/Bax ratio decreased(P<0.05)in the Cur group,showing a dose-dependent effect.Conclu-sions Cur has been shown to clear XL413-induced senescent Hep3B cells,reduce their SASP expression and promote apoptosis.The underlying mechanism may be related to the inhibition of the PI3K/AKT signaling pathway.

Aim To investigate the effects of tran-scription factor FoxO1 on acute kidney injury(AKI)induced by ischemic reperfusion injury(IRI)and to explore the underlying mechanisms.Methods Male C57BL/6 mice were randomly divided into four groups:Sham,IRI,FoxO1 inducible cell-specific knockout(FoxO1 icKO),and IRI+FoxO1 icKO.Tamoxifen(25 mg·kg-1)was intraperitoneally injec-ted to specifically knock out FoxO1 in mouse macro-phages,and a unilateral renal IRI model was estab-lished.The levels of serum creatinine(Scr),blood u-rea nitrogen(BUN),Fe2+,malondialdehyde(MDA),reactive oxygen species(ROS),and reduced glutathi-one(GSH)in renal tissues were detected.Hematoxy-lin-eosin(HE)staining was used to observe the patho-logical changes in renal tissues.Quantitative polymer-ase chain reaction(qPCR)was used to detect the mR-NA levels of inflammatory factors such as IL-1β and MCP1 in renal tissues.Western blot was used to detect the expression levels of apoptosis and ferroptosis-relat-ed proteins.Results Compared with the control group,the levels of Scr and BUN in the IRI group were significantly upregulated,the infiltration of inflammato-ry factors IL-1β,TNF-α and MCP1 increased,the pro-tein expressions of Bax/Bc12,cleaved-caspase-3/caspase-3,cytochrome C,and FTH1 in renal tissues were significantly enhanced,while the expression of GPX4 decreased.In addition,the levels of Fe2+,MDA and ROS in the renal cortex of the IRI group signifi-cantly increased,and the level of GSH markedly de-creased(P<0.05).Compared with the IRI group,the levels of Scr and BUN in the FoxO1 icKO group were significantly reduced,the infiltration of inflammatory factors was alleviated,the expression of apoptosis-relat-ed proteins in renal tissue decreased,the expression level of ferroptosis protein GPX4 increased,and the ex-pression of FTH1 decreased.The levels of Fe2+,MDA and ROS in the renal cortex decreased,and the level of GSH significantly increased(P<0.05).Conclusion Inducing the specific knockout of FoxO1 in macro-phages can alleviate AKI induced by IRI,and its mech-anism may be related to the inhibition of ferroptosis caused by IRI by FoxO1.

Objective To study the association between serum soluble growth stimulating expression factor 2(sST2),N-terminal pro-B-type natriuretic peptide(NT-probNP),and echocardiographic parameters with myocardial remodeling in patients with heart failure(HF)after acute myocardial infarction(AMI).Methods A total of 120 patients with HF after AMI admitted to the hospital from January 2023 to January 2024 were enrolled.According to the results of echocardiography during a 6-month follow-up,the enrolled patients were divided into a myocardial remodeling group and a non-myocardial remodeling group.Serum sST2,NT-proBNP and echocardio-graphic parameters were compared between groups,and the predictive value on myocardial remodeling was analyzed.Results According to the Killip heart failure classification,the patients were classified into three groups.The sST2,NT-proBNP,left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD)and left atrial diameter(LAD)showed progressive increase in the three groups,Killip Ⅱ to Killip Ⅳ(P<0.05).Conversely,left ventricular ejection fraction(LVEF)decreased across the three groups(P<0.05).Multivariate analysis found that high sST2,high NT-proBNP and high LAD were independent risk factors of myocardial remodeling in patients with HF after AMI(P<0.05).ROC curve revealed that the area under the curve(AUC)of the nomogram model was 0.82(95%CI:0.71~0.92).Hosmer-Lemeshow goodness of fit test of the model indicated that the chi-square value was 3.67(χ2=3.67,P=0.801),and it was considered that basic consistency was exhibited between the fitted probability value and actual probability value.After 1 000 times of Bootstrap repeated sampling,the calibration curve was drawn and found that the calibration curve had good consistency with the actual curve,and both were close to the ideal curve.Decision curve displayed that the net benefit of patients was higher than that of the other two extreme curves,and when the threshold probability was between 0.16 and 0.94,the model could produce better clinical benefits.Conclusion The nomogram prediction model based on serum sST2,NT-proBNP and echo-cardiographic parameters has high predictive value on myocardial remodeling in HF patients after AMI.
