Objective To explore the predictive value of serum angiopoietin-like protein 4(ANGPTL4)and C-X3-C motif chemokine ligand 1(CX3CL1)for poor prognosis in patients with acute cerebral infarction(ACI)undergoing intravascular intervention therapy.Methods A total of 180 ACI patients undergoing endovascular intervention in our department from January 2021 to February 2024 were prospectively recruited and served as the study group,and according to the prognosis,they were divided into a good prognosis group(97 cases)and a poor prognosis group(83 cases).Another 180 individuals who taking healthy checkup in the same period served as the control group.The levels of ANGPTL4 and CX3CL1 were measured by ELISA.Results The ser-um ANGPTL4 level was significantly lower while that of CX3CL1 was obviously higher in the study group than the control group(P＜0.01).The poor prognosis group had notably longer time from onset to admission and larger proportions of having NIHSS score at admission≥15 and an-terior circulation cerebral infarction,lower serum ANGPTL4 level and higher CX3CL1 level when compared with the good prognosis group(P＜0.01).Multivariate logistic regression analysis showed that time from onset to admission,NIHSS score at admission,location of cerebral infarc-tion,and CX3CL1 were risk factors,and ANGPTL4 was a protective factor for poor prognosis in ACI patients(P＜0.05,P＜0.01).ROC curve analysis showed that the AUC value of serum ANGPTL4,CX3CL1 and their combinzation in predicting poor prognosis in ACI patients was 0.816(95％CI:0.755-0.877),0.860(95％CI:0.791-0.930),and 0.901(95％CI:0.846-0.956),respectively,and the combined indicators showed better predictive value than each indicator alone(Z=2.716,Z=2.732,P＜0.05).Conclusion Serum ANGPTL4 and CX3CL1 levels are abnormal-ly expressed in ACI patients after intravascular intervention therapy,and are related to prognosis.Their combined detection can improve the predictive value for poor prognosis.

Objective:To compare the effects of intraoperative administration or non-administration of tranexamic acid (TXA) on early postoperative inflammatory response and clinical outcomes in elderly male patients with intertrochanteric femur fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 92 elderly male patients with intertrochanteric femur fractures admitted to Zhongda Hospital Affiliated to Southeast University from January 2020 to December 2022, aged 62-96 years [(79.9±8.4)years]. According to the modified Evans classification, the fractures were classified as types I-III in 33 patients and types IV-V in 59. All the patients were treated with proximal femoral intramedullary nail fixation. Among them, 46 patients received intraoperative TXA (TXA group), while 46 patients did not (non-TXA group). The operative duration, intraoperative blood loss, length of postoperative hospital stay were compared between the two groups. The serum interleukin-6 (IL-6) levels and visual analogue scale (VAS) scores at 1, 3, 5, and 7 days postoperatively were detected. The complication rate and mortality within 1 year postoperatively were also compared between the two groups.Results:All the patients were followed up for 1-12 months [(10.9±2.8)months]. No significant difference was found in the operative duration between the groups ( P>0.05). The intraoperative blood loss and length of postoperative hospital stay were 150.0(100.0, 200.0)ml and (6.8±1.9)days in the TXA group, less or shorter than those in the non-TXA group [200.0(150.0, 262.5)ml and (7.7±2.0)days] ( P<0.05). At 1, 3, and 5 days postoperatively, the IL-6 levels in the TXA group were 84.5(66.3, 100.1)pg/ml, 48.9(36.8, 61.2)pg/ml, and 27.9(19.4, 37.5)pg/ml, which were all lower than those in the non-TXA group [110.3(83.1, 162.9)pg/ml, 63.7(44.2, 84.2)pg/ml, and 32.7(22.4, 42.9)pg/ml] ( P<0.05). No statistically significant difference in the IL-6 level was observed between the two groups at 7 days postoperatively ( P>0.05). At 1 and 3 days after operation, the VAS scores in the TXA group were (4.3±0.9)points and (2.5±0.9)points, lower than those in the non-TXA group [(6.8±1.2)points and (3.0±1.2)points] ( P<0.05). There were no statistically significant differences in VAS scores between the two groups at 5 and 7 days postoperatively ( P>0.05). The complication rate within one year after operation was 28% (13/46) in the TXA group, significantly lower than 50% (23/46) in the non-TXA group ( P<0.05). No significant difference was observed in the mortality within 1 year postoperatively between the two groups ( P>0.05). Conclusion:Compared with non-administration of TXA, intraoperative administration of TXA can effectively reduce the intraoperative blood loss, shorten the length of postoperative hospital stay, significantly lower early postoperative inflammation levels, reduce early postoperative pain intensity, and decrease the incidence of complications in elderly male patients with intertrochanteric femur fractures, with no significant difference in mortality within 1 year after operation between the two groups.

Objective To investigate the value of interleukin(IL)-6 and kidney injury molecule(Kim)-1 in the early prediction of contrast-induced pnephropathy(CIN)after percutaneous coronary intervention(PCI)in patients with coronary heart disease.Methods A total of 730 patients with coronary heart disease who underwent PCI were retrospectively collected,divided into CIN group(n=46)and non-CIN group(n=684),and the medical records of the two groups were compared,and the relationship between Kim-1 and IL-6 of renal injury and CIN was analyzed by binary regression,and the receiver operating characteristic(ROC)curve was used to explore the predictive value of these two markers on CIN after PCI for coronary heart disease.Results There was no significant difference between two groups in terms of preoperative IL-6(P=0.467)and Kim-1(P=0.643),and 48h and 72h after PCI,IL-6 and Kim-1 in CIN group was higher than that in non-CIN group(P＜0.001),and IL-6 and Kim-1 in CIN group was higher than that in before surgery(P＜0.001).48h postoperative IL-6(OR=1.884,P=0.002),48h postoperative Kim-1(OR=1.409,P＜0.001)and 72h postoperative IL-6(OR=1.377,P＜0.001)and 72 hours postoperative Kim-1(OR=1.092,P=0.004)were independent risk factors for CIN.The ROC curve showed that when used as a diagnostic marker for CIN,the area under the curve(AUC)of IL-6(48h),IL-6(72h)were 0.837,0.782,AUC of 48h Kim-1 and 72h Kim-1 were 0.820 and 0.827,respectively.Conclusion IL-6 and Kim-1 are independent risk factors for CIN after PCI for coronary heart disease.IL-6 and Kim-1 were positively correlated with the occurrence of CIN after PCI for coronary heart disease.IL-6 and Kim-1 have good diagnostic sensitivity and specificity for CIN after PCI for coronary heart disease.

Objective:To investigate the feasibility of magnetic anchor technique for endoscopic submucosal dissection (ESD) in the treatment of early esophageal cancer.Methods:A self-designed magnetic anchoring device (including an anchor magnet and a target magnet) was used to perform ESD on the hypothesized esophageal lesion mucosa of six isolated esophagus of Beagle dogs. The feasibility and convenience of the operation was evaluated.Results:ESD of 6 isolated esophagus of dogs was successfully completed. Through adjusting the position of anchor magnet, the pulling direction and force of the target magnet on the mucosa could be flexibly controlled, the mucosal peeling surface was fully exposed, and tissue tension was provided to ensure the smooth removal of the diseased mucosa. The entire operation was smooth, and the target magnet was conveniently retained. No target magnet slippage or mucosal laceration occurred during the operation.Conclusion:The magnetic anchor technique is safe and feasible for the ESD, effectively pulling the diseased mucosa in treatment of early esophageal cancer, which can greatly improve the endoscopic operation experience.

To evaluate the impact of intrahepatic cholestasis on liver stiffness measurement ( LSM ) of two‐dimensional shear wave elastography ( 2D‐SWE ) in patients with chronic hepatitis B . Methods Between June 2011 and December 2016 , total of 1 188 patients with chronic hepatitis B infection were enrolled to collect clinical ,2D‐SWE ,biochemical variables and histological ( M ET AVIR scoring system ) datas . LSM was compared between normal total bilirubin group ( TB ＜ 23 .9 μmol/L ) versus abnormal TB group( ≥23 .9 μmol/L ) . Correlation of TB with LSM s was assessed . Results Nine hundred and seventy‐three patients with effective LSM in the study were analyzed . Within the same fibrosis stage ( F1‐F4) ,LSM showed significantly higher value in abnormal TB group than those of normal TB group ( r＝0 .328 ,0 .247 ,0 .495 ,0 .435 ,all P ＜ 0 .001 ) . Increased LSM for abnormal TB group was generally found within different subset of patients [ fibrosis stage ≤ F2 ,AL T ≥ 2 × upper limit of normal ( ULN ) ;fibrosis stage≤ F2 ,M ET AVIR activity grade ≤ A1 or ≥ A2 ] ,with r ＝ 0 .266 ,0 .210 ,0 .243 ( all P ＜0 .001) ,respectively .Increased LSM for abnormal TB group was also found within different subset of patients [ fibrosis stage≥F3 ,AL T＜2× ULN ,≥2×ULN ; fibrosis stage≥F3 ,M ET AVIR activity grade≥A2 ,with r ＝ 0 .671 ,0 .200 ,0 .468 ( all P ＜ 0 .05 ) ] . Conclusions Hepatogenous jaundice induced to intrahepatic cholestasis shows slight positive correlation with LSM s in patients with chronic hepatitis B .

Objective To compare the value of acoustic structure quantification(ASQ) and shear wave elastography(SWE) in the evaluation of diagnostic accuracy of liver fibrosis.Methods One hundred and thirty-five patients with chronic hepatic diseases enrolled in our study were underwent ASQ,SWE and liver biopsy.Correlation between Total Mode,BR ratio,the elastic modulus and pathological stages of liver fibrosis were analyzed by Spearman's rank test.ROC curves were set up by evaluating the degree of hepatic fibrosis through Total Mode,BR ratio,the elastic modulus.Results The significant positive correlation were observed between Total Mode,BR ratio,the elastic modulus and pathological stages of liver fibrosis(r =0.46,P =0.000; r =0.49,P =0.000; r =0.68,P =0.000,respectively).Total Mode,BR ratio,and the elastic modulus,of each pathological stages,had statistically significant differences (F =6.05,P =0.000 ; F =5.17,P =0.000; F =48.82,P =0.000,respectively).The areas under the ROC curve (AUC) set up by evaluating the pathological stages of fibrosis (S≥ 1,S≥2,S≥3 and S =4) through the elastic modulus were larger than that of Total Mode and BR ratio(all P ＜0.05).But the AUC for the diagnosis of fibrosis of Total Mode and BR ratio showed no statistically significant differences(all P ＞0.05).Conclusions SWE was more accurate than ASQ parameters (Total Mode,BR ratio) in grading hepatic fibrosis.ASQ parameters (Total Mode,BR ratio) were observed well-correlated with the pathological staging of hepatic fibrosis.
