Objective To analyze the adverse reaction reports （ADRs） of drug-induced liver injury in recent ten years, explore the characteristics and related rules of drug-induced liver injury, and provide reference for clinical safe drug use. Methods ADRs in our hospital from 2011 to 2021 which belonged to drug-induced liver injuries were collected, and Pareto analysis was carried on. Results In 259 ADR reports, the most common type of drug-induced liver injury was hepatocellular injury （37.84%）. The age of drug-induced liver injury was mainly over 46 years, totaling 195 （75.28%）. Drugs were mainly distributed in cardiovascular system medicine （44.02%）, anti-infective medicine （23.94%）and anti-tumor medicine （11.58%）. Among the cardiovascular drugs, atorvastatin calcium 40mg and over 40mg were the highest proportion, with 53 cases （46.49%）. The main anti-infectious drugs were cephalosporins （29.03%）, carbapenem （19.35%）， antifungal （17.74%）and quinolones （11.29%）. Adverse reactions occurred within 6 days （69.88%）, the duration of adverse reactions was 1-2 weeks （31.66%）, and most patients were improved （47.88%） or cured （37.07%）. Conclusion For middle-aged and elderly patients, when the application of cardiovascular system drugs, anti-infective drugs or anti-tumor drugs, it is necessary to monitor the liver function changes of patients for at least 6 days. If there are abnormalities, the drugs should be stopped or given treatment in time, to avoid the progress of drug-induced liver injury.

Objective:To comparatively evaluate the efficacy of anti-tumor necrosis factor (TNF)-α and anti-interleukin (IL)-12/23 biologics as the first-line treatment in Crohn′s disease (CD).Methods:From January 1, 2016 to December 31, 2024, at the Department of Gastroenterology of the First Affiliated Hospital of Soochow University, the clinical data of patients with CD treated with anti-TNF-α (infliximab or adalimumab) or anti-IL-12/23 biologics (ustekinumab) as first-line treatment were retrospectively collected. All the patients were followed up for 1 year since the initiation of first-line biologic treatment, with the follow-up concluding on December 31, 2024. The primary outcomes were the clinical efficacy (including clinical response rate and clinical remission rate) of anti-TNF-α or anti-IL-12/23 treatment at week 24 and week 48, and the endoscopic efficacy(including endoscopic response rate and endoscopic remission rate) at week 48. The clinical efficacy was assessed based on Crohn′s disease activity index(CDAI). The clinical response was defined as a reduction in CDAI by ≥ 70 from baseline (week 0), and clinical remission was defined as CDAI < 150. The endoscopic efficacy was assessed based on simple endoscopic score for Crohn′s disease (SES-CD), the endoscopic response was defined as a reduction in SES-CD by ≥50% from baseline (week 0), and endoscopic remission was defined as SES-CD ≤2. Chi-square test or Fisher′s exact test was used for statistical analysis.Results:A total of 215 CD patients were enrolled, including 160 males and 55 females, with the age of (31.88±11.55) years old. Among them, 179 patients completed the clinical efficacy evaluation, 110 cases were treated with anti-TNF-α, 69 cases were treated with anti-IL-12/23. The clinical response rates of patients treated with anti-TNF-α and anti-IL-12/23 at week 24 were 95.5%(105/110) and 95.7%(66/69), respectively, and the clinical remission rates at week 24 were 86.4%(95/110) and 85.5%(59/69), respectively; the clinical response rates at week 48 were 95.5%(105/110) and 97.1%(67/69), respectively, and the clinical remission rates at week 48 were 89.1%(98/110) and 88.4%(61/69), respectively; and the differences were not statistically significant(Fisher′s exact test, χ2=0.03, Fisher′s exact test, χ2=0.02; P=1.000, 0.708, 0.872, and 0.887). A total of 76 patients completed endoscopic efficacy evaluation, among which 55 cases were treated with anti-TNF-α, and 21 cases were treated with anti-IL-12/23. The endoscopic response rates of patients treated with anti-TNF-α and anti-IL-12/23 were 74.5%(41/55) and 66.7%(14/21), respectively, and the endoscopic remission rates at week 48 were 49.1%(27/55) and 28.6%(6/21), respectively; and the differences were not statistically significant( χ2=0.47 and 2.60, P=0.492 and 0.107). Conclusion:Both anti-TNF-α and anti-IL-12/23 are effective as first-line biological therapies for CD, and there are no significant differences in both clinical and endoscopic efficacy between these 2 biologics.

Objective:To compare the role of double-balloon enteroscopy (DBE) and dual-energy CT enterography (DCTE) in evaluating the clinical characteristics of Crohn′s disease (CD).Methods:From July 1, 2016 to November 1, 2023, 72 patients with CD who underwent both DBE and DCTE (with an interval of less than 3 months) in the First Affiliated Hospital of Soochow University were enrolled in this retropective study. Among them, 4 patients underwent both DBE and DCTE twice (a total of 76 cases). The data of DBE and DCTE in the diagnosis of 76 CD cases were analyzed, including the diagnostic rate of CD, the consistency of the 2 methods in detecting the lesion location (ileocecal, colonic, ileocolonic, and upper gastrointestinal tract involvement), and the detection rates of stenosis, ulcer and the location, long ulcer (long-diameter≥2 cm), and fistula. Kappa test was performed for the consistency analysis, and Chi-square test was used for statistical analysis.Results:The diagnostic rate of CD by DBE was higher than that by DCTE (80.3% (61/76) vs. 65.8% (50/76)), and the diagnostic rate of combination of the 2 methods (89.5% (68/76)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=4.04 and 12.28, P=0.044 and <0.001). The result of Kappa consistency test showed that the consistency of CD lesion location detected by DBE and DCTE was poor (Kappa value=0.29, t=3.17, P=0.002). The detection rate of stenosis by DBE was higher than that by DCTE (46.1% (35/76) vs. 13.2% (10/76)), the detection rate of stenosis by combination of the 2 methods (52.6% (40/76)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=19.73 and 26.82, both P<0.001). There were no statistically significant differences in the detection rates of fistula among DBE, DCTE, and the combination of the 2 methods (3.9%(3/76), 2.6% (2/76), 5.3% (4/76); all P>0.05). The detection rate of ulcer by DBE was higher than that by DCTE(73.7% (56/76) vs. 7.9% (6/76)), the detection rate of ulcer by combination of the 2 methods (76.3%(58/56)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=68.10 and 72.98, both P<0.001). The detection rates of long ulcer and non-terminal ileum ulcer by DBE were both 17.9% (10/56). All the 6 cases with ulcer detected by DCTE were located in the terminal ileum, and no long ulcers were observed. Conclusions:In the diagnosis of CD, as well as in the detection of stenosis and ulcer, DBE and the combination of DBE and DCTE have more advantages over DCTE alone. The consistency between DBE and DCTE in identifying the location of lesion is poor. DBE has advantages in detecting long ulcer and non-terminal ileum ulcer.

Objective:To investigate the impact and clinical value of preoperative intra-aortic balloon pump(IABP)placement on the occurrence of postoperative atrial fibrillation(POAF)in elderly high-risk patients with coronary artery disease undergoing off-pump coronary artery bypass grafting(CABG).Methods:A retrospective cohort study was conducted, selecting 128 elderly(age≥60 years)patients with coronary artery disease who underwent isolated off-pump CABG and met high-risk criteria(≥2 high-risk factors)at Beijing Tongren Hospital.According to the occurrence of POAF, patients were divided into the POAF group(38 cases)and the non-POAF group(90 cases). Preoperative baseline data, preoperative IABP usage, intraoperative and postoperative indicators were collected and compared between the two groups.Univariate analysis was used to screen for differential variables, and multivariate logistic regression analysis was performed to identify the independent risk factors for POAF, focusing on the role and impact of preoperative IABP placement on POAF occurrence.Results:Among the 128 patients included, the incidence of POAF in patients with preoperative IABP placement was lower than that in patients without preoperative IABP placement[12.12%(4/33) vs.35.79%(34/95), χ2=6.512, P=0.011]; the preoperative IABP usage rate in the POAF group was significantly lower than that in the non-POAF group[10.53%(4/38) vs.32.22%(29/90), χ2=5.488, P=0.019]; the proportion of patients with preoperative left ventricular ejection fraction(LVEF)<40% in the POAF group was significantly higher than that in the non-POAF group[23.68%(9/38) vs.10.00%(9/90), χ2=4.140, P=0.042]; and the preoperative creatinine level in the POAF group was also significantly higher than that in the non-POAF group[(90.62±29.45)μmol/L vs.(81.31±20.18)μmol/L, t=2.066, P=0.041]. Multivariate logistic regression analysis showed that preoperative LVEF<40% was an independent risk factor for POAF occurrence( OR=11.862, 95% CI: 1.083-129.875, P=0.043), while preoperative IABP placement was an independent protective factor for POAF occurrence( OR=0.095, 95% CI: 0.016~0.583, P=0.011). The comparison of intraoperative and postoperative indicators between the two groups showed that multiple indicators in the POAF group were significantly worse than those in the non-POAF group.In terms of intraoperative indicators, the mean graft blood flow(mGF)of the graft vessels in the POAF group was lower[(18.25±8.84)ml/min vs.(21.24±7.13)ml/min, t=2.015, P=0.046], while the pulsatility index(PI)was higher(2.64±1.36 vs.2.18±1.07, t=2.045, P=0.043). In terms of postoperative laboratory indicators, the level of cardiac troponin I(cTnI)on the first postoperative day in the POAF group[(15.69±11.32)μg/L vs.(11.46±10.07)μg/L, t=2.092, P=0.038], the highest postoperative creatinine level[(128.23±74.29)μmol/L vs.(96.18±48.32)μmol/L, t=2.897, P=0.004], and the highest blood lactic acid level within 24 hours[(1.78±0.53)mmol/L vs.(1.54±0.62)mmol/L, t=2.085, P=0.039]were all significantly higher.In terms of postoperative recovery indicators, the duration of vasoactive drug use[(46.41±32.08)h vs.(36.21±22.39)h, t=2.058, P=0.042], mechanical ventilation time[(16.72±11.64)h vs.(12.19±9.68)h, t=2.275, P=0.025], and intensive care unit(ICU)stay time[(73.48±60.20)h vs.(54.89±39.29)h, t=2.070, P=0.040]in the POAF group were all significantly longer.The LVEF before discharge in the POAF group was also significantly lower than that in the non-POAF group[(43.08±16.24)% vs.(48.49±13.08)%, t=1.986, P=0.049]. Conclusions:Preoperative LVEF<40% is an independent risk factor for POAF occurrence after off-pump CABG in elderly high-risk patients with coronary artery disease, and preoperative prophylactic IABP placement can significantly reduce the occurrence of POAF in this population.

Objective:To assess the association between temperature and risk of animal injury, and identifying vulnerable populations.Methods:Based on a time-stratified case-crossover design, the number of animal injuries monitored in hospitals of Guangdong Provincial Injury Surveillance System in 2011 and 2015-2016 was included, and the daily meteorological data were derived from the fifth generation of European ReAnalysis-Land, which was produced by the European Centre for Medium-Range Weather Forecasts. Conditional logistic regression combined with a distributed lagged nonlinear model was applied to analyze the association of temperature and animal-specific injuries. We also conducted stratified analysis by region, sex, age, occupation, and location of injury occurrence.Results:There was an almost linear relationship between temperature and the occurrence of animal injury. The excess risk ( ER) of animal injury was 2.65% (95% CI: 2.27%-3.04%) for a 1 ℃ rise in temperature with much higher risk of occurrence ( ER=9.34%, 95% CI: 7.57%-11.13%) for non-mammalian injury than that for mammalian injuries ( ER=2.30%, 95% CI: 1.90%-2.70%). Stratified analysis revealed that the occurrence of animal injury was more susceptible to temperature influences in urban ( ER=2.78%, 95% CI: 2.35%-3.21%), female ( ER=2.71%, 95% CI: 2.16%-3.27%), the elderly aged 60 years and above ( ER=3.05%, 95% CI: 1.65%- 4.47%), farmer ( ER=4.66%, 95% CI: 3.03%-6.32%) and agricultural area ( ER=10.63%, 95% CI: 7.57%-13.79%) than their correspondents. In terms of mammalian injury, dog bites showed the highest risk ( ER=2.71%, 95% CI: 2.12%-3.30%). In terms of non-mammalian,snake injuries were highly influenced by temperature ( ER=16.74%, 95% CI: 11.33%-22.40%). Conclusions:The ambient temperature rises could increase the risk of animal injury with much higher risk for non-mammalian than that for mammalian injuries. Our findings suggest that global warming may increase the risk and disease burden from animal injuries.

A total of 76 patients completed endoscopic efficacy evaluation, among which 55 cases were treated with anti-TNF-α, and 21 cases were treated with anti-IL-12/23. The endoscopic response rates of patients treated with anti-TNF-α and anti-IL-12/23 were 74.5%(41/55) and 66.7%(14/21), respectively, and the endoscopic remission rates at week 48 were 49.1%(27/55) and 28.6%(6/21), respectively; and the differences were not statistically significant( χ2=0.47 and 2.60, P=0.492 and 0.107). Conclusion:Both anti-TNF-α and anti-IL-12/23 are effective as first-line biological therapies for CD, and there are no significant differences in both clinical and endoscopic efficacy between these 2 biologics.

Objective:To compare the role of double-balloon enteroscopy (DBE) and dual-energy CT enterography (DCTE) in evaluating the clinical characteristics of Crohn′s disease (CD).Methods:From July 1, 2016 to November 1, 2023, 72 patients with CD who underwent both DBE and DCTE (with an interval of less than 3 months) in the First Affiliated Hospital of Soochow University were enrolled in this retropective study. Among them, 4 patients underwent both DBE and DCTE twice (a total of 76 cases). The data of DBE and DCTE in the diagnosis of 76 CD cases were analyzed, including the diagnostic rate of CD, the consistency of the 2 methods in detecting the lesion location (ileocecal, colonic, ileocolonic, and upper gastrointestinal tract involvement), and the detection rates of stenosis, ulcer and the location, long ulcer (long-diameter≥2 cm), and fistula. Kappa test was performed for the consistency analysis, and Chi-square test was used for statistical analysis.Results:The diagnostic rate of CD by DBE was higher than that by DCTE (80.3% (61/76) vs. 65.8% (50/76)), and the diagnostic rate of combination of the 2 methods (89.5% (68/76)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=4.04 and 12.28, P=0.044 and <0.001). The result of Kappa consistency test showed that the consistency of CD lesion location detected by DBE and DCTE was poor (Kappa value=0.29, t=3.17, P=0.002). The detection rate of stenosis by DBE was higher than that by DCTE (46.1% (35/76) vs. 13.2% (10/76)), the detection rate of stenosis by combination of the 2 methods (52.6% (40/76)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=19.73 and 26.82, both P<0.001). There were no statistically significant differences in the detection rates of fistula among DBE, DCTE, and the combination of the 2 methods (3.9%(3/76), 2.6% (2/76), 5.3% (4/76); all P>0.05). The detection rate of ulcer by DBE was higher than that by DCTE(73.7% (56/76) vs. 7.9% (6/76)), the detection rate of ulcer by combination of the 2 methods (76.3%(58/56)) was higher than that by DCTE alone, and the differences were statistically significant ( χ2=68.10 and 72.98, both P<0.001). The detection rates of long ulcer and non-terminal ileum ulcer by DBE were both 17.9% (10/56). All the 6 cases with ulcer detected by DCTE were located in the terminal ileum, and no long ulcers were observed. Conclusions:In the diagnosis of CD, as well as in the detection of stenosis and ulcer, DBE and the combination of DBE and DCTE have more advantages over DCTE alone. The consistency between DBE and DCTE in identifying the location of lesion is poor. DBE has advantages in detecting long ulcer and non-terminal ileum ulcer.

Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.
