Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Objective To evaluate the efficacy and safety of budesonide combined with pulmonary surfactant(PS)in the treatment of meconium aspiration syndrome(MAS)in neonates.Methods PubMed,Cochrane Central Register of Controlled Trials(Central),Embase,Web of Science,SinoMed,VIP,WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials(RCTs)of budesonide combined with PS in the treatment of neonatal MAS from inception to September 2,2023.Two researchers independently screened literature,extracted data and assessed the risk of bias of the included studies,meta-analyses were performed by using the RevMan 5.4 software.Results A total of 6 RCTs involving 544 patients were included.The results of meta-analysis showed that compared with PS group,budesonide combined with PS group had higher overall effective rate(RR=1.29,95％CI 1.17 to 1.41,P＜0.001),shorter hospital stay(MD=-6.35,95％CI-9.25 to-3.46,P＜0.001)and shorter time of oxygen inhalation(MD=-1.61,95％CI-2.23 to-0.98,P＜0.001),shorter the duration of ventilator use(MD=-26.46,95％CI-35.98 to-16.95,P＜0.001),improved the blood gas analysis indexes at each time after treatment(P＜0.05);In terms of safety,the incidence of total complications and adverse reactions in budesonide combined with PS group was significantly lower(RR=0.35,95％CI 0.25 to 0.47,P＜0.001).Subgroup analysis showed that the incidence of persistent pulmonary hypertension of the newborn(PPHN)in the budesonide combined with PS group was decreased(RR=0.38,95％CI 0.19 to 0.74,P=0.004),and the incidence of pneumorrhagia was decreased(RR=0.26,95％CI 0.10 to 0.69,P=0.007),and the difference was statistically significant;the incidence of heart failure and sepsis was not statistically significant compared with the PS group(P＞0.05).Conclusion Current evidence shows that budesonide combined with PS in the treatment of neonatal meconium aspiration syndrome can improve the symptoms and signs of MAS children,improve the blood gas analysis index,accelerate disease rehabilitation,shorten the course of the disease,can help reduce the risk of complications and PPHN,pneumorrhagia,and doesn't increase the incidence of heart failure,sepsis.Due to the limited quantity of the included studies,more high-quality and large-sample RCTs are needed to further validate the above conclusions.

Objective To summarize the clinical experience and risk factors for acute kidney injury (AKI) in neonates undergoing congenital cardiac surgery and demonstrate whether neonatal AKI after cardiac surgery was independently related to perioperative short-term outcomes. Methods Medical records of neonates undergoing congenital heart surgery from January 2014 to September 2021 were retrospectively reviewed. The patients were divided into an AKI group and a non-AKI group according to whether the AKI occured after the surgery. Multivariate logistic analysis was performed to analyze the risk factors for postoperative AKI and the relationship between postoperative AKI and postoperative short-term outcomes. Results A total of 609 patients were included. There were 395 males and 214 females with an age at surgery of 1.0-28.0 d and weight of 1.9-4.8 kg. After cardiac surgery, 139 neonates developed AKI. Multivariate logistic analysis showed that less intraoperative urine output [OR=0.96, 95%CI (0.94, 0.99), P=0.005], more intraoperative infusion of red blood cells [OR=1.49, 95%CI (1.16, 1.91), P=0.002], longer intraoperative deep hypothermic circulatory arrest time [OR=1.02, 95%CI (1.00, 1.04), P=0.020], higher vasoactive-inotropic score [OR=1.03, 95%CI (1.01, 1.04), P<0.001] and elevated lactate (increasing by 5 mmol/L) [OR=2.90, 95%CI (1.76, 4.76), P<0.001] when transferred to ICU were independent risk factors for AKI. AKI was an independent risk factor for increased in-hospital mortality [OR=12.61, 95%CI (3.00, 37.48), P<0.001]. Conclusion Less intraoperative urine output, more intraoperative infusion of red blood cells, longer intraoperative deep hypothermic circulatory arrest time, higher vasoactive-inotropic score and elevated lactate when transferred to ICU are independent risk factors for AKI. Furthermore, AKI is an independent risk factor for perioperative death after cardiac surgery.

Objective To explore the correlation between colorectal cancer tissue Janus kinase 2(JAK2)gene mutations and T cytokine 3(TCF3)protein expression with clinical pathological characteristics and prognosis,and to provide laboratory reference indicators for early evaluation of the illness severity and prognosis of colorectal cancer.Methods A retrospective analysis was conducted on the data of 50 colorectal cancer patients who were admitted from January 2016 to April 2021 and retained colon cancer and adjacent tissue wax blocks.Basic information,clinical and pathological features such as TNM staging,lymph node metastasis,and 3-year survival prognosis of the patients were collected.The wax blocks of colon cancer and adjacent tissues of patients were detected,in which Taqman fluorescence probe method was applied to detect the distribution of JAK2 gene at the rs2230724 locus AA,AG,and GG genotypes in colon cancer tissues,and immunohistochemistry method was applied to detect the positive expression rate of TCF3 protein in colon cancer and adjacent tissues.The basic information,JAK2 rs2230724 gene mutation,and TCF3 protein expression of patients with different clinical and pathological characteristics were compared,and the influencing factors of clinical and pathological characteristics of colon cancer was analyzed by logistic regression model.Kaplan Meier survival curve was applied to compare the survival prognosis of patients with JAK2 gene mutations and TCF3 protein expression in colorectal cancer tissue,and Cox regression model was applied to analyze the risk factors affecting the prognosis of colorectal cancer patients.Results The positive expression rate of TCF3 protein in colon cancer tissues was higher than that in adjacent tissues(P＜0.05).The age,BMI,proportion of GG genotype at rs2230724 locus of JAK2 gene and positive expression rate of TCF3 protein in TNM stage Ⅲ colon cancer patients were higher than those in TNM stage Ⅰ-Ⅱ patients(P＜0.05);The age,BMI,smoking rate,proportion of GG type at the rs2230724 locus of JAK2 gene in colon cancer tissue,and positive expression rate of TCF3 protein in patients with lymph node metastasis were higher than those without lymph node metastasis(P＜0.05);The results of the logistic regression model analysis showed that the influencing factors of clinical pathological features such as TNM staging and lymph node metastasis in colon cancer were age,mutation of JAK2 gene rs2230724 site in colon cancer tissue,and positive expression rate of TCF3 protein(P＜0.05).The Kaplan Meier survival curve analysis showed that patients with JAK2 gene rs2230724 GG genotype and TCF3 protein positivity in colon cancer tissue had higher cumulative all-cause mortality rates(P＜0.05).The results of univariate and multivariate Cox regression model analysis showed that independent risk factors affecting the prognosis of colorectal cancer patients include JAK2 gene rs2230724 site GG type,TCF3 protein positive expression,TNM stage Ⅲ,lymph node metastasis,and age.Conclusion The proportion of JAK2 gene rs2230724 GG type and TCF3 protein expression in colorectal cancer tissues are related to their clinical pathological characteristics and prognosis,and can be used as reference indicators for evaluating clinical pathological characteristics and predicting prognosis of colorectal cancer.

Objective To evaluate the clinical value of optic nerve sheath diameter(ONSD)measured on thin-slice CT scan in the diagnosis and prognostic assessment of cerebral venous sinus thrombosis(CVST).Methods The clinical data of patients with CVST,who were admitted to the First Affiliated Hospital of Nanjing Medical University of China to receive treatment from January 1,2016 to December 31,2022,were retrospectively analyzed.The difference in ONSD was compared between CVST patients and normal population,the postoperative changes in ONSD was analyzed.Results A total of 49 patients with CVST(CVST group)and 49 normal persons having no brain disorders(control group)were enrolled in this study.In CVST group,the preoperative ONSD was(5.33±0.50)mm,which was significantly higher than(4.40±0.40)mm in control group(P＜0.001),the postoperative ONSD remarkably decreased to(4.98±0.59)mm(P＜0.01).The difference value between postoperative ONSD and preoperative ONSD in the patients receiving pure anticoagulation treatment was not statistically significant different from that in the patients receiving endovascular treatment[(-0.43±0.22)mm vs.(-0.40±0.42)mm,P=0.84].The preoperative ONSD in the patients having intracranial hemorrhage and in the patients having no intracranial hemorrhage was(5.26±0.51)mm and(5.41±0.49)mm respectively(P=0.31),and the difference value between postoperative ONSD and preoperative ONSD was(-0.39±0.40)mm and(-0.45±0.25)mm respectively(P=0.66).At the three-month follow-up visit,the difference in ONSD between the patients having a good prognosis(mRS score being 0-2 points)and the patients having a poor prognosis was not statistically significant(P＞0.05).Conclusion ONSD that is measured on plain head CT scan can be used as a response indicator of elevated intracranial pressure in CVST patients,which can be used to monitor the changes in intracranial pressure before and after treatment,but its value in assessing the curative efficacy of different therapeutic methods needs to be further explored.

Objective To investigate the safety and efficacy of novel bioabsorbable vascular scaffold(BVS)in the treatment of patients with complex coronary artery disease.Methods This was a retrospective,matched,single-center observational study.45 patients with coronary atherosclerotic cardiopathy received BVS treatment in the cardiovascular medicine department Department of the Affiliated Hospital of Guangdong Medical University from June 2020 to June 2021(BVS),and 45 patients treated with drug-eluting stents(DES)group were selected according to matching study requirements during the same period.Baseline,surgical,and follow-up data were compared between the two groups to evaluate safety and efficacy.The main measures of safety were:surgical time,intraoperative adverse events,etc.,and the end point of efficacy was target lesion failure(TLF),including cardiac death,target vessel myocardial infarction,and ischa-driven target lesion revascularization.Results A total of 90 patients were enrolled in this study,all of whom were followed up for at least 3 years.There were 20 cases of bifurcation lesions and 25 cases of diffuse long lesions in the two groups,and 50 cases of imaging were reviewed among the 90 patients.The proportion of stable coronary heart disease,history of diabetes,history of hypertension,history of smoking,pre-dilated balloon pressure and postoperative diastolic blood pressure in BVS group was higher than that in DES group,and the proportion of family history was lower than that in DES group(all P＜0.05).There were no statistically significant differences in the rates of cardiac death,target vessel myocardial infarction,and ischemia-driven revascularization of target lesions between the two groups(all P＞0.05).Binary Logistic regression model analysis showed that the diameter stenosis ratio of target lesions was an independent risk factor for intrastent restenosis(OR 2.786,95％CI 1.096-7.081,P=0.031).Conclusions Compared with traditional DES,BVS implantation has consistent safety and efficacy in the treatment of complex coronary artery disease within 3 years.The diameter stenosis ratio of target lesions was an independent risk factor for intrastent restenosis.
