Objective To compare the effect after endovascular repair (EVAR) or open repair (OR) of ruptured abdominal aortic aneurysm (rAAA) in Department of Vascular Surgery,Beijing Anzhen Hospital.Methods Clinical data of 46 repaired rAAAs patients was retrospectively analyzed from 2005 to 2015.The difference between the EVAR group and the OR group in perioperative mortality,operation time,ICU stay,blood transfused,length of stay (LOS),complication rate were compared by x2 test and t test.Results 18 rAAA patients were repaired by EVAR,aged from 51 to 91 with a mean of (68 ±9).28 were repaired by OR,aged from 41 to 83 with a mean of (70 ± 11).Perioperative mortality was 21.0％ for EVAR and 28.6％ for OR (P ＞0.05).LOS was (15.3 ±9.5) days for EVAR,and (23.9 ± 10.5) days for OR (P ＜0.05).Blood transfused was (3 210 ± 3 780) ml for EVAR and (4 814 ± 3 392) ml for OR (P＜0.05).ICU stay time was (7.7 ±4.2) d for EVAR and (4.2 ±2.5) d for OR (P＜0.05).Conclusion EVAR is a reliable approach for the treatment of acute rAAA.

Objective: To investigate the current status and psychosocial determinants of health behavior among primary and middle school students in Henan province,and to provide a reference for the direction and priority of the health education in primary and middle schools. Methods: Through cluster sampling method, 3 603 primary school students age 9 to 15 and 2 791 secondary school students in Henan Province were investigated with Chinese version of the Adolescent Lifestyle Questionnaire(C-ALQ), General Self-efficacy Scale(GSES), Perceived Social Support Scale(PSSS), Resilience Scale for Chinese Adolescents(RSCA), Self-Esteem Scale(SES) during January to June in 2016. Results: The total score of health behavior among primary and middle school students was (80.30±16.36).There were significant differences in health behaviors among students with different gender(P<0.05), age(P<0.01), family income(P<0.01), body mass index(P<0.01), father’s education level (P<0.01) and mother’s education level(P<0.01). Health behaviors were significantly correlated with self-efficacy(r=0.26-0.42, P<0.01), social support(r=0.23-0.39, P<0.01), mental resilience(r=0.26-0.37, P<0.01), and self-esteem(r=-0.28--0.18, P<0.01). Gender, age, family monthly income, BMI, parents’ education level, self-efficacy, psychological resilience, social support and self-esteem was psychosocial determinants of healthy behaviors(P<0.05). Conclusion The engagement in health behaviors among primary and middle school students in Henan province is acceptable. Demographic and psychosocial determinants of health behaviors among primary and middle school students should be considered in health education curriculum planning.

Objective To evaluate the perioperative and long-term effects of endovascular aneurysm repair(EVAR) of infrarenal abdominal aortic aneurysm (AAA).Methods Clinical data of 131 AAA cases undergoing EVAR were retrospectively evaluated for the safety and long-term efficacy.Results The operative time was (137 ±29) min,blood loss was (142 ±20) ml,blood transfusion was (46 ± 26) ml,ICU staying time was (17 ± 4) h.Major perioperative complications were severe heart failure in 8 cases,myocardial infarction in 2 cases,pulmonary complications in 5 cases,internal leakage in 4 cases.During the period of up to 60 months there were15 cases of endoleak including 8 cases of type Ⅰ,5 cases of type Ⅱ,1 each case of type Ⅲ and Ⅳ and 2 deaths.By Kaplan-Meier survival analysis there were complications developing after 60 months and up to 40％ of them needing reintervention.Conclusions Endovascular repair is the safe treatment for AAA,but discharged patients need close long-term follow-up.Complications that ensued need intensive management.

Objective To explore the feasibility and safety of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in patients with severe bilateral carotid stenosis.Methods From Jul 2003 to Sep 2017,unilateral CEA or CAS were performed in 1 046 patients,213 of which were with severe bilateral carotid stenosis.These 213 patients were divided into CEA group and CAS group according to procedures taken.The perioperative outcomes of 213 patients were analyzed retrospectively.Results The incidence of typical cerebral ischemia symptoms of CEA group was higher than that in CAS group (25.3％ vs.13.3％,P =0.029).The incidence of perioperative death or stroke in CEA group was 5.63％ (4/71),which had no significant difference with that in CAS group (2.82％,4/142) (P =0.524).Conclusion Based on adequate preoperative assessment and reasonable surgical selection,CEA and CAS are both safe and feasible for the unilateral lesion during one-stage operation for patients with severe bilateral carotid stenosis

Objective:To investigate the efficacy of postmastectomy radiotherapy (PMRT) for human epidermal growth factor receptor 2 (HER2)-positive T 1-2N 1M 0 breast cancer in the context of HER2-targeted therapy. Methods:This study collected the clinical data of 105 female patients with HER2-positive T 1-2N 1M 0 breast cancer who underwent modified radical mastectomy in the First Affiliated Hospital of Bengbu Medical College from January 2013 to December 2019. Then, the clinical outcomes of these patients were observed, and the prognostic factors and the efficacy of PMRT were analyzed. Results:The median follow-up time was 50 months (ranging from 14 to 107 months), and the 5-year overall survival (OS), local-regional recurrence-free survival(LRFS), and disease-free survival (DFS) were 81.6%, 91.9%, and 76.2%, respectively. The multivariate analysis indicated that independent prognostic factors for OS and DFS include the age, pathologic grade, and tumor size; the independent risk factors for LRFS include positive lymph node ratio (LNR) and hormone receptor (HR) status; and the independent prognostic factor for DFS was PMRT (HR: 2.85, 95% CI: 1.10-8.80, P < 0.05). The subgroup analysis suggested that PMRT significantly improved the OS of various high-risk subgroups ( χ2=4.01-9.18, P < 0.05). However, the further stratified analysis indicated that PMRT only increased the OS of the patients who did not receive HER2-targeted therapy in various high-risk subgroups ( χ2=4.50-6.70, P < 0.05), while there was no statistical difference before and after PMRT for the individuals who received targeted treatment ( P > 0.05). Conclusions:PMRT is an independent prognostic factor for the DFS of patients with HER2-positive T 1-2N 1M 0 breast cancer who underwent modified radical mastectomy. PMRT can improve the OS of high-risk patients with ages < 45 years old, pathologic grade Ⅲ, tumor diameter ≥ 3 cm, LNR > 10%, and HR (-) who received no HER2-targeted therapy. However, the efficacy may be compromised to some extent in the context of the application of HER2-targeted therapy.

Objective:To compare carotid endarterectomy (CEA) and carotid artery stenting (CAS) in perioperative, medium and long term prognosis of patients with carotid artery stenosis.Methods:A retrospective analysis was performed on 1 329 cases of carotid artery stenosis treated at Department of Vascular Surgery, Beijing Anzhen Hospital from Jan 2011 to Aug 2020, as all cases being divided into CAS group and CEA group.Results:There were significant differences in age ( t=0.098, P=0.023) and drinking habits ( χ2=8.055, P=0.005) between the two groups. There were more unstable plaques in CEA group ( χ2=4.392, P=0.038), and more bilateral lesions in CAS group ( χ2=9.673, P=0.038). In perioperative period, there were more mannitol use in CEA group ( χ2=78.614, P<0.001), more incision/puncture site complications ( χ2=5.158, P=0.035), lung infection ( χ2=6.355, P=0.013), cerebral hyperperfusion syndrome (CHS) ( χ2=5.158, P=0.035) and extracranial nerve injury ( χ2=23.760, P<0.001) in CEA group than in CAS group, and more acute renal failure in CAS group ( χ2=10.393, P=0.001). There was no significant difference in survival rate and ischemic stroke, myocardial infarction, cerebral hemorrhage and renal insufficiency between the two groups (all P>0.05). The mean survival time of CAS group was 53.195 months (95% CI: 52.040-54.350), and 54.492 months (95% CI: 53.790-55.195) in CEA group ( P=0.051). Conclusions:Patients in CEA group had more unstable plaque and a lower perioperative stroke rate. CEA group had higher risk of CHS,while CAS was with lower postoperative lung infection rate and less wound local complications. There was no significant difference in long-term survival between the two groups.

ObjectiveTo explore the effect of trunk control training during unstable sitting on knee pain and function in patients with patellofemoral pain syndrome. MethodsFrom January, 2019 to December, 2021, 41 patients with patellofemoral pain syndrome in Beijing Rehabilitation Hospital were randomly divided into control group (n = 20) and experiment group (n = 21). Both groups accepted routine rehabilitation, and the experiment group accepted trunk control training during unstable sitting in addition, for four weeks. They were assessed with Visual Analogue Scale for pain (VAS) and Anterior Knee Pain Scale (AKPS), and measured stability indexes with Balancer before and after treatment. ResultsAll the VAS score, AKPS score, and the overall, anterior-posterior and left-right stability indexes improved in both groups after treatment (|t| > 12.089, P < 0.001); and improved more in the experiment group than in the control group (|t| > 5.864, P < 0.001). ConclusionTrunk control training during unstable sitting may improve knee pain and function, and motor control.
