Objective To study the significance of S100A12 in patients with acute pancreatitis (AP).Methods 139 patients with AP were divided into the severe acute pancreatitis (SAP) and moderate acute pancreatitis (MAP) groups.61 patients in the SAP group were further subdivided into the infection group (n =32) and the non-infection group (n =29) based on the presence/absence of secondary infection.Serum samples of these patients were collected on the 3rd,7th and 14th day after treatment.ELISA was used to determinate the S100A12,IL-1 β and IL-6 levels in serum.The area under ROC was used to evaluate the predictive role of S100A12,IL-1β,IL-6 and CRP for infection in patients with SAP.Results The S100A12,IL-1β and IL-6 levels in SAP patients were markedly higher than those in MAP patients and normal controls on the 3rd,7th and 14th day after treatment.These levels decreased toward normal range in MAP patients.They were persistently high in SAP patients after treatment for 7 days,but decreased significantly after 14 days.The serum levels of S100A12,IL-1β,IL-6 and CRP were significantly higher in the infection subgroup(647.5 ± 300.1,155.9 ±48.5,95.7 ±25.5,166.8 ±53.0) than the non-infection subgroup(249.0 ± 176.3,108.0 ± 46.1,64.0 ±38.5,117.9 ±34.9) (P ＜0.05).The sensitivity and specificity of serum S100A12 in diagnosing secondary infection in SAP were 96.8％ and 83.3％,which were higher than those of serum IL-1β,IL-6 or CRP.Conclusion The level of S100A12 was associated with systemic inflammatory response syndrome (SIRS) in AP,and it may serve as a new marker in early diagnosis of SAP and in secondary infection in SAP.

Objective To study the risk factors related to the severity of post-ERCP hemorrhage in the patients with choledocholithiasis.Methods Clinical data of 56 patients with choledocholithiasis and post -ERCP hemorrhage from January 2008 to August 2015 were analyzed.Made the occurrence of severe hemorrhage as dependent variable,supposed 18 factors in patients and procedure related aspects as possible covariates,analyzed with univariate and binary logistic regression.Results Severe hemorrhage was occurred in 1 1 patients after ERCP.Among patients related factors,female,history of oral corticosteriod,level of bilirubin,size of stone,periampullary diverticula, prolonged time of bleeding-cruor,acute cholangitis,acute pancreatitis and course of disease were proved to be signifi-cant risk factors by univariate analysis(P<0.01 ).Periampullary diverticula,prolonged time of bleeding-cruor and acute cholangitis were independent risk factors in further multivariate analysis(P=0.023,0.036,0.045).Among procedure related factors,EPBD(P<0.01),EST(P<0.01),residual biliary stones(P=0.029)were proved to be significant risk factors by univariate analysis,and EPBD was found as independent risk factor(P=0.029)by multiva-riate analysis.Conclusion Appearance of periampullary diverticula,prolonged time of bleeding -cruor and acute cholangitis were considered as risk factors related to severity of post-ERCP hemorrhage in patients with choledocholi-thiasis.Moreover,EPBD was also an independent risk factor which might aggravate severity of post-ERCP hemor-rhage.

PURPOSE: . The aim of this study was to evaluate the clinical performance and reliability of plasma sprayed nanostructured zirconia (NSZ) coating. MATERIALS AND METHODS: . This study consisted of three areas of analysis: (1) Mechanical property: surface roughness of NSZ coating and bond strength between NSZ coating and titanium specimens were measured, and the microstructure of bonding interface was also observed by scanning election microscope (SEM). (2) Biocompatibility: hemolysis tests, cell proliferation tests, and rat subcutaneous implant test were conducted to evaluate the biocompatibility of NSZ coating. (3) Mechanical compatibility: fracture and artificial aging tests were performed to measure the mechanical compatibility of NSZcoated titanium abutments. RESULTS: . In the mechanical study, 400 μm thick NSZ coatings had the highest bond strength (71.22 ± 1.02 MPa), and a compact transition layer could be observed. In addition, NSZ coating showed excellent biocompatibility in both hemolysis tests and cell proliferation tests. In subcutaneous implant test, NSZcoated plates showed similar inflammation elimination and fibrous tissue formation processes with that of titanium specimens. Regarding fatigue tests, all NSZ-coated abutments survived in the five-year fatigue test and showed sufficient fracture strength (407.65-663.7 N) for incisor teeth. CONCLUSION . In this study, the plasmasprayed NSZ-coated titanium abutments presented sufficient fracture strength and biocompatibility, and it was demonstrated that plasma spray was a reliable method to prepare high-quality zirconia coating.

Objective:To explore the application value of enhanced recovery after surgery (ERAS) in laparoscopic radical resection of bladder cancer and ileal bladder surgery under modular operation procedures.Methods:A retrospective selection of 42 cases of laparoscopic radical radical resection of bladder cancer and ileal bladder surgery performed by the Department of Urology, General Hospital of Southern Theater Command from January 2017 to December 2019 were divided into two groups according to the different management methods adopted during the perioperative period: ERAS management group and conventional management group, each with 21 cases. Among them, patients in the ERAS management group were managed by ERAS during the perioperative period, and patients in the conventional management group were managed by conventional management during the perioperative period. The postoperative hospital stay, first exhaust time, first defecation time, first time to get out of bed, first liquid food time, postoperative visual analogue scale (VAS) score, as well as transferrin, upper arm circumference, body mass index, plasma albumin, total protein, and total protein were compared between the two groups of patients after surgery. The measurement data conforming to the normal distribution were expressed as mean±standard deviation ( Mean± SD), and the in dependent t-test was used for comparison between groups; the measurement data of non-normal distribution were expressed as the median (interquartile range) [ M( P25, P75)], the independent sample Mann-Whitney U test was used for comparison between groups; the Chi-square test was used for comparison of enumeration data between groups. Results:The postoperative hospital stay in the ERAS group was (8.9±1.8) d, the first exhaust time was (33.4±3.2) h, the first defecation time was (60.3±7.8) h, the first time to get out of bed was (23.1±6.7) h, the first liquid food time was (82.7±18.5) h and postoperative VAS was (1.3±0.6), that were significantly reduced compared with the conventional treatment group [(12.3±2.3) d, (51.4±5.2) h, (73.0±8.1) h, (34.7±8.2) h, (109.7±21.6) h, (3.6±0.8)], the difference were statistically significant ( P<0.05). In the ERAS group, the decreased value of transferrin was [0.8 (-0.4, 2.2) g/L], the decreased value of body mass index was[1.61±0.73], the decreased value of plasma albumin was [3.5±1.5 g/L], the decrease value of total protein was[10.1±5.6 g/L] and the decrease value of prealbumin was [90.5±11.3 mg/L] were significantly lower than those of the conventional management group[(1.9(0.9, 3.6) g/L, (2.32±1.05) kg/m 2, (9.6±2.0) g/L, (16.3±4.9) g/L, (131.3±7.4) g/L], and the difference were statistically significant ( P<0.05). Conclusion:Modular laparoscopic precision resection of bladder cancer and ERAS concept after ileal bladder surgery is beneficial to shorten the hospital stay, reduce postoperative pain, have less impact on the patient′s body loss and immune function, and can speed up the patient′s postoperative recovery.

Objective:To investigate the predictive value of fluid-attenuated inversion recovery (FLAIR) signal strength ratio (SIR) in onset time≤4.5 h in patients with acute ischemic stroke.Methods:A retrospective analysis was performed; 180 acute ischemic stroke patients admitted to Department of Neurology, Nanjing Hospital Affiliated to Nanjing Medical University from January 2020 to June 2023 were chosen. Hypoperfusion intensity ratio (HIR) was used to evaluate the collateral circulation (poor collateral circulation: HIR≤0.4; good collateral circulation: HIR>0.4); clinical data and imaging indexes between poor collateral circulation and good collateral circulation groups were compared. Univariate and multivariate Logistic regressions were used to analyze the influencing factors for onset time≤4.5 h in patients with acute ischemic stroke. Correlation between SIR and onset time was analyzed in patients with acute ischemic stroke. Role of HIR as agency between SIR and onset time was explored. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of SIR and diffusion weighted imaging (DWI)-FLAIR mismatch in onset time≤4.5 h in acute ischemic stroke patients.Results:Of the 180 patients, 100 were into the good collateral circulation group and 80 were into the poor collateral circulation group; compared with the good collateral circulation group, the poor collateral circulation group had significantly higher percentage of patients with hyperlipidemia, larger DWI infarction volume before treatment, larger perfusion weighted imaging (PWI)-DWI mismatch volume and higher SIR ( P<0.05). In these 180 patients, 76 had onset time≤4.5 h and 104 had onset time>4.5 h. Univariate Logistic regression analysis showed that hyperlipidemia, DWI infarct volume before treatment, DWI-FLAIR mismatch, HIR and SIR were influencing factors for onset time≤4.5 h in acute ischemic stroke patients ( P<0.05). Multivariate Logistic regression analysis showed that hyperlipidemia ( OR=6.654, 95% CI: 5.751-8.824, P<0.001), HIR ( OR=0.724, 95% CI: 0.521-1.321, P=0.041) and SIR ( OR=739.881, 95% CI: 383.296-14 258.065, P<0.001) were independent influencing factors for onset time≤4.5 h in acute ischemic stroke patients. Pearson correlation analysis showed that SIR was positively correlated to onset time in patients with acute ischemic stroke ( r=0.420, P<0.05), and SIR was positively correlated to onset time in patients from poor collateral circulation group ( r=0.781, P<0.05). ROC curve showed that AUC of SIR in predicting onset time≤4.5 h was 0.917 (95% CI: 0.814-1.000, P<0.001) and that of DWI-FLAIR mismatch in predicting onset time≤4.5 h was 0.530 (95% CI: 0.509-0.757, P=0.075) in poor collateral circulation group, enjoying significant difference in predictive efficacy. Conclusion:Acute ischemic stroke patients with low HIR and SIR have higher odds of onset time≤4.5 h; SIR can more accurately predict the onset time in these patients with poor collateral circulation.
