Objective To explore the mechanism of personality between attachment and defense style in college students. Methods 291 students were surveyed with Eysenck Personality Questionnaire-R Short Scale (EPQ-RSC, Chinese Adaptation), Experience of Close Relationship Inventory(ECR, Chinese Adaptation) and Defense Style Questionnaire ( DSQ). Results ①Unmature defense style had significant positive correlations with anxiety, avoidance, neurotism and psychoticism(r = 0. 19,0.45,0.51,0. 19, P<0.01) ,and had significant negative correlation with extroversion(r= -0. 25, P<0. 01 ) . ②Extroversion acled as part meditator between attachment and unmature defense style. ③Neurotism served as part meditator between anxiety and unmature defense style. Conclusion Attachment is a remarkable predictor of unmature defense style and has indirect influence on it through neurotism and psychoticism.

Objective To study the ego identity,mental health and their relationship among students in athletes.Methods 110 students in athletes and 122 athletes in students were measured with identity status scale and athletes' symptom checklist.Results ①Students in athletes have higher "present serf-commitment" (5.09±1.07)and lower "crisis in the past"(2.19±1.12)than athletes in students.The two demonstrate the obvious difference on the distribution of identity status.The percentage of students in athletes obtaining A is lower than that of athletes in students ,while the percentage of students in athletes obtaining D and MD is higher. ②Comparing with the norm,students in athletes have higher level on the factors of sematizafion (1.98±0.42),compulsion (2.21±0.51),interpersonal sensitivity(2.09±0.53),depression (1.85±0.53),anxiety ( 2.47 ～0.58 ),paranoid (1.98±0.21),psychoticism (1.79±0.22) and total average marks (2.00±0.34),lower level on the factors of hostility (1.43±0.48)and cognitive(1.64±0.31). ③Three domains of ego identity exit obvious negative correlation with the sores of psychological symptoms.ANOVA confined that the more advanced ego identity is,the better mental health is.Conclusion Ego identity and mental health of students in athletes have their own features,and ego i-dentity will influence mental health.

Objective:To evaluate the effect of surgery on 47 patients with moyamoya disease by retrospective analysis.Methods:A total of 47 patients with moyamoya disease were enrolled from August,2010 to According to the improved treatment in August,2013,all cases were divided into two groups:a pre-improved group and a post-improved group.According to different surgical methods,they were divided into two subgroups:an indirect revascularization subgroup and a combined revascularization subgroup.Results:The cerebral ischemia in 77.4％ of patients was relieved after the surgery.There was significant difference in outcomes of patients between the pre-improved group and the post-improved group (P＜0.05),while there was no significant difference between the pre-improved indirect revascularization subgroup and the pre-improved combined revascularization subgroup.There was also no significant difference between the post-improved indirect revascularization subgroup and the post-improved combined revascularization subgroups (P＞0.05).Conclusion:Surgical treatment can improve the outcomes of patients with moyamoya disease,but there is no significant difference in surgical effects between indirect and combined revascularization.

Objective To evaluate the clinical effect of the endovascular treatment of iliac vein compression syndrome.Methods Thirty-three patients with iliac vein compression syndrome were treated with endovascular treatment.Of which,edema and varicose vein of the left lower extremity in 29 patients,complicated with acute deep vein thrombosis of left lower extremity in 3 patients,post deep venous thrombosis syndrome in 1 patient.Balloon dilatation and stent implantation were performed in all 33 patients.The diameter of balloon was 10-12 mm,diameter 12-14 mm Bard self expandable stent.Five patients with varicose vein and ulcer of left lower extremity were treated with two stage operation.Results The diagnosis was confirmed by left lower extremity deep veins angiography.There was no death patient,and no hematoma of hematoma locus.Follow-up for 3-30 months,the rate of follow-up was 100％(33/33).The edema of the lower extremity was markedly reduced or disappeared in 28 patients.Color Doppler ultrasound and left lower extremity angiography showed that the stent was unobstructed,no stent occlusion and new onset thrombosis cases.Conclusion Endovascular treatment is safe,effective with few complications,and is the first choice for the treatment of iliac vein compression syndrome.

Objective To determine the level of peripheral blood CD34 positive (CD34+) cells in patients with acute cerebral infarction (ACI),and to explore its clinical significance.Methods The level of peripheral blood CD34+ cells was determined by flow cytometry within 72 hours of onset of patients with acute cerebral infarction (infarct group,n=45),cerebrovascular risk factors in patients without cerebral infarction (high risk group,n=27) and healthy subjects (control group,n=20).The neural function defect score,infarction lesion volume and carotid artery intima-media thickness (IMT) were determined in patients with infarction group.Results The percentages of peripheral blood CD34 cells in infarction group (0.034 ±0.012)％ and the high risk group of patients (0.047±0.009)％ were lower than that of control group(0.063±0.009)％,and were lower in infarction group than in high-risk groups (all P＜0.05).The percentages of peripheral blood CD34+cells were significantly decreased compared with control group (P＜0.05) in infarction patients with mild [(0.047±0.009)％],moderate [(0.036±0.009)％],severe [(0.022±0.007)％] infarction nervous function defect score.Wherein,the percentages were lower in severe group than in the moderate group,moderate group was lower than in mild group (all P＜0.05).The percentages of peripheral blood CD34 cells in infarction patients with small,moderate,large infaret lesion volume were lower than in control group (P＜0.05),wherein,were lower in large group than in moderate group,lower in moderate group than in treatment group (all P＜0.05).Infarction patients were confirmed with carotid atherosclerosis (CAS) by carotid ultrasound.The extent of lesion were divided into carotid artery intimal thickening group [(0.043±0.010)％],carotid artery plaque group [(0.036±0.010)％],and carotid artery stenosis group [(0.023±0.009)％].The levels of peripheral blood CD34+ cells in three groups of patients were decreased compared with control group.The levels were lower in carotid artery stenosis group than in carotid artery plaque group,lower in carotid artery plaque group than in carotid artery intimal thickening group (all P＜0.05).Conclusions The level of peripheral blood CD34+ cells in acute cerebral ischemia is reduced,it can become a sensitive and early indicator of cerebral ischemia,and its level is related to neurologic impairment,infarction size and the degree of carotid artery atherosclerosis.

Objective To observe the efficacy and safety of prednisone combined with leflunomide in the treatment of immu-noglobulin A(IgA)nephropathy.Methods Eighty patients with IgA nephropathy were selected and divided into the treatment group and control group.The patients in the control group were given prednisone and the treatment group received prednisone plus leflunomide.The treatment course lasted for 12 months.Total effective rate,serum creatinine(Scr),urinary protease inhibitor C(Cys C),blood urea nitrogen(BUN)and 24 h proteinuria(U-prot)were measured at 6-month and 12-month treatment.Serum levels of vascular endothelial growth factor(VEGF)and endothelin-1(ET-1)were measured by enzyme-linked immunosorbent assay (ELISA).Results The effective rates at 6-month and 12-month treatment in the treatment group were 85% and 90% respective-ly,which in the control group were 65% and 70% respectively,the difference between the two groups was statistically significant (P<0.05).The BUN and U-prot levels after 6-moth and 12-month treatment were significantly reduced,moreover the effect in the treatment group was better than that in the control group(P<0.05).The levels of plasma VEGF and ET-1 after 6-moth and 12-month treatment in the two groups were decreased,moreover the decrease range in the treatment group was greater than that in the control group(P<0.05).Conclusion Prednisone combined with leflunomide can significantly improve the renal function in the pa-tients with IgA nephropathy,and it is safe and effective.

Objective To explore the efficacy of middle and high (mid-high) flow intracranial-external vascular bypass in treatment of complex intracranial aneurysms and selection of grafts. Methods The clinical data of 79 patients with complicated intracranial aneurysms treated by mid-high flow extracranial-intracranial bypass in our hospital from August 2010 to October 2017 were collected retrospectively. The grafts were radial artery (n=21), saphenous vein of the calf segment (n=29) or thigh saphenous vein segment (n=29). The efficacy was determined based on Glasgow outcome scale (GOS) scores at discharge and modified Rankin scale (mRS) scores at follow-up, and the differences of occlusion in different types of grafts were analyzed. Results CTA showed patency of the grafts in all patients one d after surgery. There were 6 patients having vascular occlusion: 2 patients (the grafts at saphenous vein of the calf segment ) were occluded 3 and 4 d after surgery, without symptom; 2 patients (the grafts at the radial artery), with decreased limb muscle strength, were occluded 5 and 25 d after procedure; 2 patients ( the grafts at the saphenous veins of the calf segment) were occluded 6 months after procedure without any symptom. There were 4 patients developed cerebral ischemia after operation: one had cerebral infarction and three had vasospasm. GOS scores at discharge and mRS scores at follow-up showed that 78 patients had improved symptoms and good prognosis; one patient showed no improvement in symptoms and plant survival. Conclusion Mid-high flow extracranial-intracranial bypass for treatment of complex intracranial aneurysms is effective; the graft should be individually selected based on preoperative assessment results.

Objective To investigate the role of network platform for treatment and rescue of acute and severe cerebrovascular diseases in improving treatment level of patients with acute ischemic stroke.Methods The differences of number of patients accepted venous thrombolysis, number of patients accepted emergency intravascular interventional treatment, and time from admission to intravenous thrombolysis (door to needle time [DNT]) were analyzed in patients with acute ischemic stroke admitted to our hospital in the first year (2016) and the second and third years (2017 and 2018) of construction of network platform for treatment and rescue of acute and severe cerebrovascular diseases in Yunfu city. The National Institutes of Health Stroke Scale (NIHSS) scores were compared in 120 patients selected randomly from online referral (study group,n=60) and non-online referral (control group,n=60) within the same time periods in 2018.Results In 2017 and 2018, the number of patients accepted intravenous thrombolysis was 85 and 103, respectively, and the rate of intravenous thrombolysis was 9.92％ and 9.83％; they were all significantly larger/higher than those in 2016 (n=50, 6.97％,P<0.05). In 2017 and 2018, the number of patients accepted emergency endovascular treatment was 56 and 129, respectively, and the emergency endovascular treatment rate was 6.53％ and 12.31％; they were all higher than those in 2016 (n=44 and 6.14％), and the differences between those in 2018 and 2016 were statistically significant (P<0.05). The DNT ([82.00±18.75] min in 2017 and [77.00±32.17] min in 2018) was significantly shorter than that in 2016 ([109.00±30.58] min,P<0.05). The NIHSS scores of the study group and control group were 4.70±3.64 and 8.90±5.62, respectively, after one week of treatment, both of which were lower than those before treatment (14.30±6.29 and 13.60±6.37); and after treatment, the NIHSS scores of the treatment group were statistically lower than those of the control group (P<0.05). Conclusion Construction and effective operation of network platform for treatment and rescue of acute and severe cerebrovascular diseases is an effective guarantee to improve the success rate of treatment for patients with acute ischemic stroke.

Objective To summarize the experiences of endovascular aortic repair (EVAR) for isolated iliac artery aneurysm (ⅡAA).Methods The clinical data of 23 patients with ⅡAA undergoing EVAR from Aug 2008 to Mar 2016 were retrospectively analyzed.There were 5 cases of internal iliac artey (internal iliac artery ⅡA) aneurysm,10 cases of unilateral common iliac artery(common iliac artery CIA) aneurysm,6 cases of bilateral CIA aneurysms.Unilateral ⅡA aneurysm was treated by coil embolization and covering the entrance;CIA aneurysm without involving ⅡA was treated by EVAR with covered stent,those involved unilateral ⅡAs or combined ⅡA aneurysms were treated by EVAR after ⅡA embolization.Those with bilateral ⅡA involvement were repaired by Sandwich technique;Bilateral ⅡA was treated in two phases.Results All endovascular procedures were successfully performed;No patients died during the perioperation period.Intraoperative endoleak found in 5 cases managed by balloon dilatation,or conservatively were cured.23 patients were followed-up for 2-60 months,one rebuilding ⅡA was occluded.One CIA anurysm complicated with endoleak was cured by coils embolization and stenting.Gluteal claudication and erectile dysfunction occured in 4 out of 15 cases with unilateral or bilateral ⅡAs occlusion.Conclusion EVAR is a safe and effective treatment for ⅡAA,after a proper management for ⅡA.
