Objective To explore the effect of different needle track management on Yttrium-90 microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on liver cancer after liver biopsy. Methods A retrospective analysis was conducted on the clinical data of 21 patients with liver cancer who underwent Technetium-99m-macroaggregated albumin (^99mTc-MAA) evaluation and ⁹⁰Y-SIRT after liver biopsy from June 2023 to December 2024. The methods of needle track management, hepatic arteriovenous shunting, and lung shunt fraction (LSF) were recorded. The occurrence of hepatic arteriovenous fistula (HAVF), as well as the corresponding countermeasures were analyzed. Results Among the 21 liver cancer patients, 7 cases (medical glue group) underwent embolization of the needle tract with medical glue (N-butyl 2-cyanoacrylate [NBCA]) immediately after biopsy, and no significant HAVF was observed during the ^99mTc-MAA tests; 14 cases (non-medical glue group) were treated with delayed needle extraction or gelatin sponge particle blocking after biopsy, among which 7 cases developed significant HAVF, and the fistulas were treated with NBCA. The LSF of the medical glue group was significantly lower than that of the non-medical glue group ([7.06±2.33] % vs [12.43±7.73] %, P＝0.037). All 21 patients successfully completed ⁹⁰Y-SIRT. Conclusions Liver biopsy may affect ⁹⁰Y-SIRT by causing iatrogenic HAVF. Immediate NBCA-embolization of the needle tract after biopsy or timely NBCA-embolization of fistulas during ^99mTc-MAA tests may reduce the impact.

Objective:To investigate the early and mid-term outcomes of aortic endovascular remodeling device (AERD) for Stanford type A aortic dissection (TAAD) in type Ⅱhybrid surgery, and to evaluate its clinical efficacy.Methods:46 patients with TAAD, including 14 females and 32 males, participated in the single-center clinical trial of West China Hospital of Sichuan University and underwent type II hybrid surgery (Bentall / ascending aorta replacement + AERD implantation) from February 2021 to October 2023. The safety and efficacy of AERD in type Ⅱ hybrid surgery for TAAD were estimated by clinical indicators (postoperative mortality, cardiovascular and cerebrovascular accidents, paraplegia, ischemia), and blood flow condition (volume of the true and false lumen, and suprachial branches).Results:Three patients (6.52%) died during the follow-up period, and the operation-related mortality was 4.35% (2/46). The remaining 43 patients were followed up for an average of (25.53±9.60) months. There were two cases (4.35%) of stroke after the operation, and paraplegia, acute renal insufficiency, and other severe complications were not noticed. The blood flow of the superior branch of the aortic arch was unobstructed, and there was no significant difference in the blood flow of the branch before the operation and at each follow-up time point. Compared to the pre-operation, the true lumen volume of the stent part increased by 59.0% and the false lumen volume decreased by 82.4%.Conclusion:AERD is a safe and effective alternative in type II hybrid surgery for acute TAAD, which is helpful in improving perioperative and short- and long-term survival rates and clinical outcomes.

Isocitrate dehydrogenase (IDH) is an essential metabolic enzyme in the tricarboxylic acid cycle (TAC). The high mutation frequency of the IDH gene plays a complicated role in gliomas. In addition to affecting gliomas directly, mutations in IDH can also alter their immune microenvironment and can change immune-cell function in direct and indirect ways. IDH mutations mediate immune-cell infiltration and function by modulating immune-checkpoint gene expression and chemokine secretion. In addition, IDH mutation-derived D2-hydroxyglutarate can be absorbed by surrounding immune cells, also affecting their functioning. In this review, we summarize current knowledge about the effects of IDH mutations as well as other gene mutations on the immune microenvironment of gliomas. We also describe recent preclinical and clinical data related to IDH-mutant inhibitors for the treatment of gliomas. Finally, we discuss different types of immunotherapy and the immunotherapeutic potential of IDH mutations in gliomas.

Objective:To observe the changes of neutrophil to lymphocyte ratio and lung function of patients defined by different TCM syndromes with acute exacerbation of chronic obstructive pulmonary disease.Methods:A total of 181 patients with acute exacerbation of chronic obstructive pulmonary disease in our hospital from January 2016 to Novenber 2018 were included and divided into 5 groups accoding to different TCM syndromes, which were wind-cold invading lung syndrome (26), external cold and internal fluid syndrome (40), phlegm-heat obstructing lung syndrome (48), phlegm-dampness blocked syndrome (48), an heart spirit confused by phlegm syndrome (19). Then tested the blood for each group, and calculated NLR; tested c-reactive protein, and lung function, and measured with COPD Assessment Test (CAT) and Modified British Medical Research Council (mMRC); conducted 6MWT, then the BODE index and Charlson Comorbidity Index (CCI) scores were calculated.Results:The NLR, CRP level in patients with external cold and internal fluid syndrome and an heart spirit confused by phlegm syndromeby phlegm were significantly higher than those of other syndrome ( P<0.05 or P<0.01), and FEV1% Pred was significantly lower than that of phlegm-dampness blocked syndrome ( P=0.024); the 6-minute walking distance of patients with external cold and internal fluid syndrome was significantly shorter than that of phlegm-heat obstructing lung syndrome and phlegm-dampness blocked syndrome ( P=0.006, P=0.024). The comparison of mMRC grades among the syndromes was statistically significant ( F=26.367, P=0.049). The BODE index of patients external cold and internal fluid syndrome was higher than that of patients phlegm-heat obstructing lung syndrome ( P=0.015), and the CCI score of patients an heart spirit confused by phlegm syndrome was higher than that of patients phlegm-dampness blocked syndrome ( P=0.012). The BODE index of patients with external cold internal fluid syndrome was significantly higher than that of phlegm-heat obstructing lung syndrome ( P=0.015). The CCI score of patients with mental disorder caused by phlegm was significantly higher than that of phlegm-dampness blocked lung syndrome ( P=0.012). Conclusions:There were significantly differences in neutrophil to lymphocyte ratio, CRP and 6-minute walking distance among different TCM syndromes in patients with acute exacerbation of chronic obstructive pulmonary disease. The inflammation in patients with external cold and internal fluid syndrome and mental disorder caused by phlegmare much severe, but there might be no difference in dyspnea and prognosis among TCM syndromes.

Objective: To improve physical activity by assessing pedometer-based physical activity during specific intervals over a week, among junior high school students,and to provide a reference for improving the level of students’ physical activity. Methods: Students (n=675) of grades 6-8 from six public junior high schools in Shanghai were recruited and instructed to wear a pedometer for a week, step counts and contents were recorded over a specific period. This period mainly included steps taken on the way to and from school, at school, at home in the evening on weekdays, and in the morning, afternoon, and evening on weekends. Results: The daily step counts recorded were 8 332 steps, with those on weekdays showing significantly higher values than step counts on weekends (9 065 steps vs. 6 392 steps)(t=22.9, P<0.01). Proportionately, the physical activity level at school contributed more to daily step counts (61.3%), followed by those on the commute to and from school(25.5%). Boys were more active than girls. For all intervals on weekdays, the step counts of students in rural districts, with overweight or obese, in grades 6 and 7, were higher than those in urban districts, with normal status, in grade 8 respectively (P<0.05). Low-activity students with physical education were more active than one without physical education(t boy=1.99,t girl=2.45,P<0.05). Conclusion These findings facilitate the implementation of effective, feasible interventions to enhance physical activity over a series of intervals during the day.

Objective: To investigate the value of karyotype analysis, bacterial artificial chromosomes-on-beads (BoBs), chromosome microarray analysis (CMA) and fluorescence in situ hybridization (FISH) in the diagnosis of sex chromosome numerical and structural abnormalities. Methods: Conventional G-banding staining technique was used to analyze the karyotypes of amniotic fluid cells and parental peripheral blood cells in two pregnancies with prenatal diagnosis indications. Sex chromosome numerical and structural abnormalities were analyzed based on the results of G-banding, BoBs, CMA and FISH. Results: The results of G-banding karyotype analysis showed that there were mosaics in amniotic fluid cells collected from both cases. Karyotype of Case A was 45,X[25]/46,X,idic(Y)(q11.2?)[6], and Case B was 45,X[39]/46,X,psu idic(X)(q21.32?)[44]. Parental peripheral blood karyotypes of both families were normal. Prenatal BoBs indicated copy number abnormalities in sex chromosomes (Y chromosome in Case A and X chromosome in Case B). CMA results suggested a 20.1 Mb duplication in Yp11.32q11.222, and a 7.7 Mb deletion in Yq11.222q11.23 in fetus A with possible karyotype of 46,X,idic(Y)(q11.222); for fetus B, a 92.0 Mb duplication in Xp22.33q21.32, and a 63.0 Mb deletion in Xq21.32q28 were detected, and the karyotype might be 46,X,psu idic(X)(q21.32). The mid-term FISH test of amniotic fluid cells showed that 90% of the amniotic cells from Case A were 45,X, and 10% were 46,X,idic(Y)(q11.2); about 38% were 45,X, and 62% were 46,X,psu dic(X)(q21.3) from Case B. Conclusions Numerical and structural abnormalities of sex chromosomes could be accurately diagnosed by combination of several methods including G-banding karyotype analysis, prenatal BoBs, CMA and FISH, which would help to effectively reduce birth defects.

Objective To investigate the incidence of left ventricular hypertrophy (LVH) in peritoneal dialysis (PD) patients with different hydration statuses,and analyze the risk factors of LVH in PD patients.Methods PD patients in Renji Hospital,Shanghai Jiao Tong University School of Medicine from September 2016 to January 2017 were enrolled.Demographic data of patients were collected and biochemical parameters were measured.Hydration status index overhydration (OH) was measured by bioimpedance spectroscopy,and LVH was diagnosed by echocardiography.Logistic regression was used to analyze the risk factors of LVH.Results A total of 113 PD patients aged 58.98(48.89,65.33) years with median PD duration 46.20(18.08,72.75) months were enrolled in present study,among whom 60 patients (53.1％) had LVH.OH ＞ 1.1 L was detected in 80 patients (70.8％),among whom 34 patients (42.5％) had subclinical overhydration (SCOH).LVH was however diagnosed in 33(71.7％) clinical overhydrated (COH) patients and 17(50.0％) SCOH patients (n=34).In the normal hydrated (OH≤1.1 L) patients (n=33),LVH was detected in 10 patients (30.3％).Multivariate logistic regression showed that high OH (OR=1.730,95％CI 1.274-2.348,P ＜ 0.001) and low hemoglobin (OR=0.965,95％CI 0.940-0.991,P=0.008) were the independent risk factors of LVH.Conclusions LVH is common in PD patients,especially in overhydrated patients.High OH and low hemoglobin were the independent risk factors of LVH.
