ObjectiveTo explore the impacts of material type and loading volume of rigid containers on the hydrogen peroxide low temperature plasma sterilization of thoracoscopic instruments, to identify the best rigid containers and loading volume of thoracoscopic instruments. MethodsThoracoscopic instruments sterilized by STERRAD^® 100NX hydrogen peroxide low temperature plasma in Shanghai Pulmonary Hospital affiliated to Tongji University from August to September 2024 were selected as the research items. According to the material of rigid containers, the instruments were divided into polyethylene case group (A), stainless steel case group (B) and silicone resin case group (C). In terms of the loading volume, the rigid containers were divided into (loading capacity <80%) groups of 8, 10 and 12 instruments. The results of physical monitoring, the first type of chemical indicator card monitoring, and the five types of card luminal chemical process challenge device (PCD) monitoring of the 9 groups of A8, A10, A12, B8, B10, B12, C8, C10 and C12 were compared and evaluated. ResultsCompared to A8, A10 A12, C8, C10 or C12 groups, the thoracoscope instruments in the stainless steel containers in B8, B10 or B12 group had higher hydrogen peroxide concentrations and shorter elapsed time in the pressure check phases 1 and phases 2, with the differences statistically significant (P<0.05), followed by the silicone resin case group and the polyethylene case group. The nine groups of physical parameter monitoring, the first type of chemical indicator monitoring, and the five types of chemical PCD monitoring for lumen sterilization achieved 100% qualification rates, and there were no significant differences in the qualified rates of sterilization among the 9 groups (P>0.05). ConclusionWhen using hydrogen peroxide low temperature plasma to sterilize thoracoscopic instruments, it is recommended to use stainless steel or silicone resin rigid containers with a controlled loading capacity (≤12) to ensure optimal sterilization quality.

Objective To analyze the risk factors and re-intervention strategies for mid- and long-term residual after arterial switch operation (ASO). Methods The clinical data of children with complex congenital heart disease who underwent ASO surgery in Shanghai Children’s Medical Center from January 2006 to June 2022 were retrospectively collected, and the risk factors for mid- and long-term residual after ASO were analyzed. Results A total of 952 children undergoing ASO were enrolled in this study, including 654 males and 298 females with an average age of (102.9±90.1) d and weight of (4.6±1.6) kg. There were 421 patients with D-transposition of the great arteries with intact ventricular septum (D-TGA/IVS), 357 patients with D-transposition of the great arteries with ventricular septal defect (D-TGA/VSD), and 174 patients with right ventricle double outlet combined with subpulmonary ventricular septal defect (Taussig-Bing malformation). Eighty-nine patients died early after the surgery, the mortality rate was 9.3%. The 746 surviving children were regularly followed up after the surgery (follow-up rate 86.4%), with a median follow-up time of 79.4 (12.0-188.0) months. During the follow-up, 53 children underwent surgical re-intervention due to residual, including 33 males and 20 females, with a median age of 62.5 (17.0-214.0) months. The median surgical weight was 19.0 (8.2-86.0) kg, and the mean time of re-intervention was 28.0-170.0 (77.5±45.4) months after the ASO. Residual problems included common trunk and branch stenosis of the pulmonary artery in 23 patients, right ventricular outflow tract (RVOT) obstruction in 11 patients, left ventricular outflow tract obstruction in 6 patients, aortic arch restenosis in 5 patients, aortic insufficiency in 5 patients, residual shunt of ventricular septal defect in 2 patients, and tricuspid valve insufficiency in 1 patient. The early postoperative mortality rate was 3.8% (2/53), with the causes of death being acute myocardial infarction due to coronary artery injury and acute left heart failure, respectively. The mean follow-up time of the surviving children was (52.4±28.6) months, and no mid- and long-term death occurred. Two patients underwent the third operations due to pulmonary restenosis. The multivariate analysis result showed that combined aortic arch surgery and early postoperative RVOT velocity>3 m/s were independent risk factors for mid- and long-term residual after ASO. Conclusion ASO is an ideal procedure for the treatment of D-TGA/IVS, D-TGA/VSD and Taussig-Bing malformations. Combined aortic arch surgery and early postoperative RVOT velocity>3 m/s are independent risk factors for mid- and long-term residual after ASO.

Objective To analyze the clinical efficacy of right midaxillary straight incision surgery in the treatment of doubly committed subarterial ventricular septal defect. Methods The clinical data of children with doubly committed subarterial ventricular septal defect who received surgeries in our hospital from August 2020 to July 2023 were analyzed retrospectively. All the children underwent surgical repair and were divided into two groups according to the incision position, including a right midaxillary straight incision group and a median incision group. The outcomes were compared between the two groups. Results A total of 187 patients were enrolled. There were 102 patients in the right midaxillary straight incision group, including 55 males and 47 females with a median age of 26.0 (5.0, 127.0) months and a median weight of 12.5 (5.1, 32.8) kg at surgery. There were 85 patients in the median incision group, including 37 males and 48 females with a median age of 4.0 (2.0, 168.0) months and a median weight of 6.7 (4.8, 53.9) kg at surgery. No mortality occurred in the study. There was no statistical difference between the two groups in the cardiopulmonary bypass time [(50.0±18.4) min vs. (46.1±15.7) min] or aortic cross-clamping time [(31.3±18.6) min vs. (26.3±17.5) min] (P>0.05). Compared to the median incision group, the time from the end of cardiopulmonary bypass to the closure of chest [(22.3±15.6) min vs. (37.1±13.4) min, P<0.001], postoperative hospital stay [(6.9±3.9) d vs. (8.6±3.6) d, P=0.002], the length of incision [(4.3±2.7) cm vs. (8.5±3.2) cm, P<0.001], drainage volume [(79.0±32.2) mL vs. (100.2±43.1) mL, P<0.001], and the pain score on the 2nd and the 3rd day after the operation were statistically better in the right midaxillary straight incision group (P<0.05). The medical experience and incision satisfaction scores at discharge of the right midaxillary straight incision group were higher (P<0.05). During the follow-up of 21.0 (1.0, 35.0) months, no residual shunt was detected and all patients in both groups had a normal cardiac function and mild or less valve regurgitation. Conclusion Compared to the median incision, minimally invasive right midaxillary straight incision for the repair of doubly committed subarterial ventricular septal defect offers comparable efficacy and reliability, with the added advantages of being minimally invasive, cosmetically superior, and promoting faster postoperative recovery.

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.

Objective We aimed to evaluate the efficacy and safety of Shengxuebao Mixture in the treatment of cancer-related anemia(CRA)presenting with syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood.Methods A randomized,double-blind,placebo-controlled,multicenter clinical trial was conducted.Eligible patients with malignant tumors meeting the inclusion and exclusion criteria were enrolled from 26 hospitals,including Dongzhimen Hospital,Beijing University of Chinese Medicine,Xiaogan Central Hospital,and Yangzhou Hospital of Traditional Chinese Medicine,from June 1,2022,to September 30,2024.Patients were allocated 1:1 to either the experimental group receiving Shengxuebao Mixture or the control group receiving its simulator(placebo)using a block randomization method under double-blind conditions.Both groups received 15 mL orally three times daily for 28 consecutive days.The primary efficacy indicators included the hemoglobin(Hb)improvement rate(RHb)and the traditional Chinese medicine(TCM)syndrome improvement rate(RTCM)at week 4 of treatment.The secondary efficacy indicators encompassed Hb and red blood cell(RBC)count,Karnofsky Performance Status(KPS)score,TCM syndrome score,individual TCM symptom scores,and changes in each of these indicators compared to the baseline period at weeks 2,4,and 6 of treatment.Safety evaluations were conducted at week 4 of treatment.Results A total of 239 patients were enrolled,with 225 cases included in the Full Analysis Set(FAS)(109 in the experimental group vs.116 control group),163 in the Per Protocol Set(PPS)(77 vs.86),and 225 in the Safety Set(SS)(109 vs.116).Baseline characteristics between groups showed no significant differences.Significant differences were observed between the experimental and control groups in RHb at week 4(FAS:49.51%vs.35.24%,P<0.05;PPS:53.25%vs.36.05%,P<0.05)and RTCM at week 4(FAS:61.54%vs.39.62%,P<0.01;PPS:64.94%vs.40.70%,P<0.01).At weeks 2,4,and 6,the experimental group showed greater improvements in Hb and RBC counts than the control group.Additionally,the TCM syndrome scores were lower in the experimental group than in the control group at these time points.Except for week 2 in PPS,the KPS improvement was better in the experimental group than in the control group(P<0.05).The experimental group also demonstrated a greater reduction in scores for individual TCM symptoms such as spiritlessness and weakness,poor appetite and reduced food intake at weeks 4 and 6 compared to the control group(P<0.05,P<0.01).Furthermore,the reduction in vertigo score was more pronounced in the experimental group at week 6(P<0.01).For the score of pale and lusterless complexion,only in the PPS was the reduction from baseline more significant in the experimental group than in the control group at weeks 4 and 6(P<0.05).No significant differences were observed between the experimental and control groups in the incidence of all adverse events or drug-related adverse reactions.Conclusion Shengxuebao Mixture demonstrates significant efficacy in patients with CRA presenting syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood,effectively increasing Hb levels,ameliorating TCM syndromes,alleviating clinical symptoms,and enhancing functional status,with no significant difference in adverse drug reactions compared to the placebo.

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.
