Objective To evaluate the performance of the Quality of Life Instrument for Chronic Dis-ease Nephrotic Syndrome [QLICD-NS(V2.0)] in patients with nephrotic syndrome.Methods A total of 203 patients with nephrotic syndrome (NS) diagnosed in the Department of Nephrology,Affiliated Hospital of Guangdong Medical University from March 2021 to November 2021 were selected for QLICD-NS(V2.0) eval-uation,and the evaluation methods were generalization theory (GT) and item response theory (IRT).The dif-ficulty,discrimination coefficient and information amount of each item were obtained by using Multilog 7.0 software to analyze the grade response model (GRM) of IRT.Results The results of GT showed that the contribution ratio of the global total score in the four domains of QLICD-NS(V2.0) scale was evenly distribu-ted,and the generalization coefficient of the four domains was greater than 0.50.Except for social function,the variance component of the participants in the other three domains were greater than the item variance compo-nent,and the reliability index of each domain was greater than 0.50.The results of IRT showed that the dis-crimination degree of QLICD-NS(V2.0) scale was 0.82.Except for items TNS7 and TNS8,the difficulty coef-ficients of the other items ranged from -3 to 3 and increase monotonically.Conclusion The QLICD-NS (V2.0) scale has good reliability in physiological function and psychological function,and is acceptable in so-cial field and special function.The QLICD-NS(V2.0) scale developed in this study has good performance.

Objective:To explore the surgical strategies and clinical efficacy for aortic dissection combined with refractory superior mesenteric artery (SMA) ischemia.Methods:This is a retrospective case series study. Clinical data of 24 patients with aortic dissection and refractory SMA ischemia admitted to the Department of Vascular Surgery, Zhongshan Hospital, Fudan University from August 2010 to August 2020 were retrospectively collected. Of the 24 patients, 21 were males and 3 were females, with an age of (50.3±9.9) years (range: 44 to 72 years).Among them, 9 cases were Stanford type A aortic dissection, and 15 cases were type B. All patients underwent CT angiography upon admission, and based on imaging characteristics, they were classified into three types. Type Ⅰ: severe stenosis/occlusion of the SMA true lumen only; Type Ⅱ: stenosis of the true lumens in the descending aorta and SMA (isolated type); Type Ⅲ: stenosis of the true lumens in the thoracoabdominal aorta and SMA (continuation type). Surgical procedures, complications, mortality, and reintervention rates were recorded.Results:Among the 24 patients, 17 (70.8%) were classified as Type Ⅰ, 4 (16.7%) as Type Ⅱ, and 3 (12.5%) as Type Ⅲ. Fourteen cases of Type Ⅰ underwent thoracic endovascular aortic repair combined with SMA stent implantation. Additionally, 3 Type Ⅰ and 1 Type Ⅱ patients underwent only SMA reconstruction (with one case of chronic TAAD treated with iliac artery-SMA bypass surgery). Moreover, 3 Type Ⅱ and 3 Type Ⅲ patients underwent descending aorta combined with SMA stent implantation. There were 5 patients (20.8%) who underwent small bowel resection, either in the same sitting or in a staged procedure. During hospitalization, 4 patients died, resulting in a mortality rate of 16.7%. Among these cases, two patients succumbed to severe intestinal ischemia resulting in multiple organ dysfunction syndrome. The follow-up duration was (46±9) months (range: 13 to 72 months). During the follow-up, 2 patients died, unrelated to intestinal ischemia. The 5-year freedom from reintervention survival rate was 86.1%, and the 5-year cumulative survival rate was 82.6%.Conclusions:Patients with aortic dissection and refractory SMA ischemia have a high perioperative mortality. However, implementing appropriate surgical strategies according to different clinical scenarios can reduce mortality and alleviate intestinal ischemia.

Objective:To evaluate the clinical outcomes of thoracic endovascular aortic repair (TEVAR) in the treatment of Stanford type B aortic dissection (TBAD) in Marfan syndrome patients who had no history of aortic arch replacement.Methods:This is a retrospective case-series study. From January 2009 to December 2019,the clinical data of Marfan syndrome patients who underwent TEVAR for TBAD at the Department of Vascular Surgery were collected. A total of 23 patients were enrolled,including 15 males and 8 females. The age was (38.0±11.0) years (range:24 to 56 years). Among them,12 patients had history of ascending aortic surgery. Details of TEVAR,perioperative complications and reintervention were recorded and survival rate was analyzed by Kaplan-Meier curve.Results:Technical success was 91.3% (21/23). Two patients with technical failure were as follows:one patient had type Ⅰa endoleak at the completion angiography,which healed spontaneously during the follow-up,and the other patient suffered aortic intimal intussusception after the deployment of the first stent-graft, and the second stent-graft was deployed. However, type Ⅲ endoleak was detected,which disappeared during the follow-up. One patient died during hospitalization. The median follow-up time ( M(IQR)) was 60 (48) months (range:12 to 132 months). Reintervention was performed on 7 patients,including 3 distal stent-graft-induced new entry,2 distal aortic dilation,1 Ⅰa endoleak and 1 retrograde type A aortic dissection,respectively. Five-year cumulative survival rate was 86.7% (95% CI:86.6% to 86.8%) and the 5-year freedom from reintervention rate was 81.8% (95% CI:61.8% to 92.8%). Conclusions:TEVAR is feasible in the treatment of TBAD in Marfan syndrome patients who has no history of aortic arch replacement. It has high technical success rate and low perioperative complication.

Objective:To examine the effect of short-term regular aerobic exercise on physical fitness of children with pulmonary with atresia ventricular septal defect after radical biventricular treatment.Methods:This was a prospective self pre-and post-control observation study. The subjects performed regular aerobic exercise for 10 days according to the exercise prescription. Body composition measurement and cardiopulmonary exercise test[lung ventilation function, maximum oxygen uptake(VO 2max), maximum oxygen pulse(O 2/HR max), ventilation oxygen uptake efficiency(OUES), exercise load time], 6 min walking distance(6MWD), sports psychometric test, motor function screening test and fitness test, were collected. The changes of test parameters and scale scoring before and after exercise were analyzed and compared. Results:A total of 7 children with PA/VSD after biventricular surgery were enrolled. The age ranged 8.2-16.2 years old, and there were 2 males and 5 females. VO 2max[(1 196.71±395.31)ml/min vs.(1 297.43±425.73)ml/min, P=0.031], O 2/HRmax[(82.43±7.53)ml/beat vs.(91.57±6.95)ml/beat, P<0.001]increased after exercise. The exercise load time was significantly increased compared with that before intervention[(476.43±35.73)s vs.(531.43±45.76)s, P=0.002]. Resting heart rate before exercise( P=0.013) and peak respiration exchange ratio(PeakRER, P=0.021) were significantly lower. Body composition tests suggest weight, intracellular water, protein and muscle content of lower limb were higher( P<0.05). The motor function score was higher than before( P=0.015); the score of sports fear was lower than before( P=0.009). There was no significant difference in lung capacity and 6-minute walking distance before and after exercise( P>0.05). There were no cardiovascular events during the study period. Conclusion:Short-term regular aerobic exercise for children with PA/VSD after biventricular surgery can improve exercise tolerance, increase lower limb muscle content, improve exercise fear and exercise function, and has good safety and feasibility.

There is currently a huge worldwide demand for donor kidneys for organ transplantation. Consequently, numerous marginal donor kidneys, such as kidneys with microthrombi, are used to save patients' lives. While some studies have shown an association between the presence of microthrombi in donor kidneys and an increased risk for delayed graft function (DGF) (McCall et al., 2003; Gao et al., 2019), other studies have demonstrated that microthrombi negatively impact the rate of DGF (Batra et al., 2016; Hansen et al., 2018), but not graft survival rate (McCall et al., 2003; Batra et al., 2016; Gao et al., 2019). In contrast, Hansen et al. (2018) concluded that fibrin thrombi were not only associated with reduced graft function six months post-transplantation but also with increased graft loss within the first year of transplantation. On the other hand, Batra et al. (2016) found no significant differences in the DGF rate or one-year graft function between recipients in diffuse and focal microthrombi groups. To date, however, the overall influence of donor kidney microthrombi and the degree of influence on prognosis remain controversial, necessitating further research.

OBJECTIVES: Stroke has become the leading cause of death and disability among adults in China. This study aims to analyze the disease burden based on gender and age and the risk factors for stroke subtypes in China 2019, and to provide reference for targeted stroke prevention and control. METHODS: Based on 2019 data of the Global Burden of Disease (GBD), the gender and age in patients with different stroke subtypes (ischemic stroke, intracranial hemorrhage, subarachnoid hemorrhage) in China 2019 was described by using disability-adjusted life years (DALY), and attributable burden of related risk factors was analyzed. RESULTS: In 2019, the burden of intracranial hemorrhage was the heaviest one in China, resulting in 22.210 6 million person years of DALY, following by ischemic stroke and subarachnoid hemorrhage, resulting in 21.393 9 and 2.344 7 million person years of DALY, respectively. Among them, except the 0-14 age group, the disease burden of different subtypes of stroke in men was higher than that in women. The disease burden of ischemic stroke was increased with age in both men and women, with the heaviest disease burden in ≥70 years group. The disease burden of intracranial hemorrhage and subarachnoid hemorrhage was the heaviest in males aged 50-69 years old, and in females aged ≥70 years and 50-69 years, respectively. Metabolic factors were the main risk factors in all ages of different stroke subtypes, and the most important risk factor was high systolic blood pressure. Other risk factors were different between men and women. Smoking, high body mass index, high low-density lipoprotein, and outdoor particulate matter pollution were the main risk factors for stroke in men, while high body mass index, outdoor particulate matter pollution, and high fasting blood glucose were the main risk factors of stroke in women. The main risk were different among different age groups. CONCLUSIONS The burden and attributable risk factors for different stroke subtypes are discrepancy in different gender and age groups. Targeted interventions should be conducted in the future to reduce the burden of stroke.
