Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.

ObjectiveTo understand the infection characteristics of multidrug-resistant organisms (MDROs) in hospitalized patients in a tertiary sentinel hospital in Shanghai, so as to provide an evidence for the development of targeted prevention and control measures. MethodsData of MDROs strains and corresponding medical records of some hospitalized patients in a hospital in Shanghai from 2021 to 2023 were collected, together with an analysis of the basic information, clinical treatment, underlying diseases and sources of sample collection. ResultsA total of 134 strains of MDROs isolated from hospitalized patients in this hospital were collected from 2021 to 2023 , including 63 strains of methicillin-resistant Staphylococcus aureus (MRSA), 57 strains of carbapenem-resistant Acinetobacter baumannii (CRAB), and 14 strains of carbapenem-resistant Klebsiella pneumoniae (CRKP). Of the 134 strains, 30 strains were found in 2021, 47 strains in 2022 and 57 strains in 2023. The male-to-female ratio of patients was 2.05∶1, with the highest percentage (70.90%) in the age group of 60‒<90 years. The primary diagnosis was mainly respiratory disease, with lung and respiratory tract as the cheif infection sites. There was no statistically significant difference in the distribution of strains between different genders and infection sites (P>0.05). However, the differences in the distribution of strains between different ages and primary diagnosis were statistically significant (P<0.05). Patients who were admitted to the intensive care unit (ICU), had urinary tract intubation, were not artery or vein intubated, were not on a ventilator, were not using immunosuppresants or hormones, and were not applying radiotherapy or chemotherapy were in the majority. There was no statistically significant difference in the distribution of strains for whether received radiotherapy or chemotherapy or not (P>0.05), while the differences in the distribution of strains with ICU admission history, urinary tract intubation, artery or vein intubation, ventilator use, and immunosuppresants or hormones use or not were statistically significant (all P<0.05). The type of specimen was mainly sputum, the hospitalized ward was mainly comprehensive ICU, the sampling time was mainly in the first quarter throughout the year, the number of underlying diseases was mainly between 1 to 2 kinds, the application of antibiotics ≥4 kinds, and those who didn’t receive any surgery recently accounted for the most. There were statistically significant differences in the distribution of strains between different specimen types, wards occupied and history of ICU stay (P<0.05), but no statistically significant difference in the distribution of strains between different sampling times, number of underlying diseases and types of antibiotics applied (P>0.05). ConclusionThe situation of prevention and control on MDROs in this hospital is still serious. Focus should be placed on high-risk factors’ and infection monitoring and preventive measures should be strengthened to reduce the incidence rate of MDROs infection.

Fusion genes are new sequences formed by the recombination of two or more gene fragments in the genome that play an important biological role and have clinical significance in the proces of tumorigenesis and development.The detection of fusion genes can provide important guidance for early diagnosis,risk stratification and targeted therapy of tumors.Traditional fusion gene detection methods dominate clinical applications,but have limitations such as low sensitivity,high cost or technical complexity,making them difficult to apply on a large scale.Fortunately the rapid advancements of new biotechnology,a series of new fusion gene detection methods are gradually emerging,providing new alternatives for fusion gene detection.This article reviews traditional fusion gene detection methods and the sequencing technologies developed in recent years,aiming to provide ideas for the detection of fusion genes and guidance for the diagnosis and precise treatment of related diseases.

Background and Aims:Acute lower extremity deep vein thrombosis (DVT) is a common clinical condition. In the acute phase,it can lead to secondary complications such as acute pulmonary embolism (PE) and limb swelling,while in the chronic phase,it may result in post-thrombotic syndrome (PTS),posing significant health risks. Early mechanical thrombectomy can restore venous patency,alleviate symptoms,and reduce the incidence of PTS. AngioJet percutaneous mechanical thrombectomy (PMT) offers the advantages of rapid and efficient thrombectomy with fewer complications,making it widely used in clinical practice. However,there are currently no standardized guidelines at home or abroad regarding the choice of access route for PMT. This study was performed to compare the clinical outcomes and effects on venous valve function of antegrade versus retrograde AngioJet PMT for treating acute lower extremity DVT,aiming to explore the optimal surgical approach for thrombectomy.Methods:A prospective,randomized controlled study was conducted,enrolling 96 patients with acute lower extremity DVT treated at the Department of Vascular Surgery,Beijing Jishuitan Hospital,Capital Medical University,from January 2022 to June 2024. Patients were divided into an antegrade group and a retrograde group based on the direction of operation and valve opening. Surgical outcomes and risks were evaluated for both groups,and factors influencing the 3-month postoperative venous patency rate were analyzed.Results:A total of 92 patients were finally included,with 47 cases in the antegrade group (51.1％) and 45 cases in the retrograde group (48.9％),all treated with AngioJet PMT. Baseline characteristics showed no significant differences between the two groups (all P>0.05). In the antegrade group,14 cases (29.8％) had thrombus interception by filters,with 7 cases (14.9％) being effective;4 cases (8.5％) developed new or worsened PE. In the retrograde group,18 cases (40.0％) had thrombus interception by filters,with 8 cases (17.8％) being effective;5 cases (11.1％) developed new or worsened PE. No significant differences were observed between the two groups in these or other safety and laboratory variables (all P>0.05). The antegrade group had a higher proportion of intraoperative manual aspiration thrombectomy compared to the retrograde group (68.1％ vs. 26.7％,P<0.001). However,there were no significant differences in thrombus grade Ⅲ clearance rate (61.7％ vs. 68.9％),3-month venous patency rate (93.6％ vs. 91.1％),or other perioperative variables (all P>0.05). Regression analysis of factors affecting 3-month venous patency showed that immediate venous patency (OR=3.043,95％ CI=0.993-1.209) and radiation dose (OR=0.868,95％ CI=-0.001-0.000) in the antegrade group,as well as immediate venous patency (OR=2.333,95％ CI=0.655-0.980) in the retrograde group,were significantly associated with 3-month patency rate (all P<0.001). Regression analysis also showed a significant linear relationship between immediate venous patency and VCSS/Villalta scores in both groups (all P<0.001). Conclusion:Both antegrade and retrograde AngioJet PMT procedures are equally safe and effective for treating acute lower extremity DVT. However,the risk of intraoperative thrombus detachment remains high,warranting the use of inferior vena cava filters to prevent fatal PE. Patients with immediate venous patency require standardized postoperative management and follow-up to prevent PTS.

Background::Somatic copy number variations (SCNVs) in the CDKN2A gene are among the most frequent events in the dysplasia-carcinoma sequence of esophageal squamous cell carcinoma. However, whether CDKN2A SCNVs are useful biomarkers for the risk stratification and management of patients with esophageal squamous cell dysplasia (ESCdys) is unknown. This study aimed to investigate the characteristics and prognostic value of CDKN2A SCNVs in patients with mild or moderate (m/M) ESCdys. Methods::This study conducted a prospective multicenter study of 205 patients with a baseline diagnosis of m/M ESCdys in five high-risk regions of China (Ci County, Hebei Province; Yanting, Sichuan Province; Linzhou, Henan Province; Yangzhong, Jiangsu Province; and Feicheng, Shandong Province) from 2005 to 2019. Genomic DNA was extracted from paraffin biopsy samples and paired peripheral white blood cells from patients, and a quantitative polymerase chain reaction assay, P16-Light, was used to detect CDKN2A copy number. The cumulative regression and progression rates of ESCdys were evaluated using competing risk models. Results::A total of 205 patients with baseline m/M ESCdys were enrolled. The proportion of ESCdys regression was significantly lower in the CDKN2A deletion cohort than in the diploid and amplification cohorts (18.8% [13/69] vs. 35.0% [28/80] vs. 51.8% [29/56], P <0.001). In the univariable competing risk analysis, the cumulative regression rate was statistically significantly lower ( P = 0.008), while the cumulative progression rate was higher ( P = 0.017) in ESCdys patients with CDKN2A deletion than in those without CDKN2A deletion. CDKN2A deletion was also an independent predictor of prognosis in ESCdys ( P = 0.004) in the multivariable analysis. Conclusion::The results indicated that CDKN2A SCNVs are associated with the prognosis of ESCdys and may serve as potential biomarkers for risk stratification.
