ABSTRACT

Objective:To evaluate the safety and feasibility of the in-situ needle fenestration combined with the in vitro physician modified fenestration technique to reconstruct supra-aortic branches during thoracic endovascular aortic repair (TEVAR) for aortic arch lesions requiring landing at Z0 and Z1.Methods:From Nov 2017 to Dec 2019, eighteen patients who underwent both the in-situ needle fenestration and the in vitro physician modified fenestration techniques to extend the proximal landing zone to Z0 and Z1 during TEVAR were included in our study.Results:Sixteen patients underwent in vitro physician modified fenestration ,two patients underwent in vitro physician modified fenestration to reconstruct both the left common carotid artery and the innominate artery. All eighteen patients received in-situ needle fenestration to preserve the left subclavian artery. Supra aortic branches were preserved in all patients (38/38, 100%). There was no Type Ⅰ endoleak. Type Ⅱ endoleak was found in four paitnets (4/18). Type Ⅲ endoleak occurred in one patient (1/18). Type Ⅳ endoleak in four patients (4/18). Type Ⅲ endoleak needed open aortic arch repair 6 months later. The median follow-up time was 12 months. One (1/18) died in 12 months and the other patients were doing well.Conclusions:The joint application of the in-situ needle fenestration and the in vitro physician modified fenestration to reconstruct supra-aortic branches during TEVAR for aortic arch pathologies requiring landing at Z0 and Z1 was satisfactory.

ABSTRACT

@#Objective    To investigate the efficacy of subclavian-carotid transposition (SCT) in treating patients with proximal subclavian artery occlusive diseases who were unable to be intervened, such as failure of intervention, congenital malformation and unwillingness to intervention. Methods    A retrospective review of 19 patients with proximal subclavian artery occlusion who underwent SCT from May 2016 to December 2018 was done. There were 14 males and 5 females with an average age of 54.05±17.34 years. The advantages and disadvantages of SCT in the treatment of proximal subclavian artery occlusion were analyzed. Results    All patients achieved immediate remission of symptoms after surgery. The stenosis degree of the proximal subclavian artery decreased from 100.0%±0.0% to 12.7%±10.1% after surgery. The average blood pressure difference between the unaffected side and the affected side decreased from 11.95±10.60 mm Hg to 0.89±5.75 mm Hg (P<0.01). Peripheral nerve injury occurred in 7 (36.8%) patients. The in-patient cost of subclavian artery occlusion patients who received subclavian artery interventional therapy in our hospital during the corresponding period was 3 392.12 yuan higher than that of the SCT group in average (if eliminating the patients whose cost was far from the average value, the cost of interventional therapy was 4 812.01 yuan higher than that of the SCT group in average). During 1-3 years' follow-up, 6 patients with neurological complication relieved. One- and three-year patency rates were 100.0%. No perioperative stroke, death or re-operation happened. Conclusion    SCT is an ideal process for the patients with subclavian artery occlusion who cannot accept subclavian artery interventional therapy.

ABSTRACT

@#Aortic arch disease is one of the research hotspots and treatment difficulties in the field of aorta, including aortic arch aneurysms, pseudoaneurysm, ulcer, dissection and intramural hematoma. By summarizing the clinical data of the vascular surgery center of Fuwai Hospital of Chinese Academy of Medical Sciences in the past five years and combining with the latest theories of the cutting-edge development of aortic surgery, the authors proposed the "HENDO" concept, including using hybrid technique (H), endovascular repair (Endo) and open surgery (O), properly to treat aortic arch pathologies individually. The authors advocated the establishment of HENDO team and cooperation mechanism in large aortic centers, to eliminate technical shortcomings of a single surgeon by fully mastering the three main technology clusters by teamwork. Accordingly, the best treatment for each patient can be administrated and the survival rate and quality of life can be improved eventually.

ABSTRACT

In order to require ideal proximal landing zone and durable long-term outcome, it is necessary to reconstruct the left subclavian artery(LSA) blood supply as much as possible in thoracic aortic endovascular repair(TEVAR). With the advent and progress of diverse assisted techniques and devices, several procedures for the reconstruction of the left subclavian artery have been developed and widely utilized, including surgical LSA bypass or transposition, chimney technique, periscope technique, fenestration and branched stent-graft, which have expanded the proximal landing zone and widened the indication for original TEVAR. This article describes the advantages and pitfalls of each revascularization methods. Anatomies of aortic arch and LSA, urgency and types of pathologies, proficiency of the surgeon with different revascularization techniques and pre-operative risk score of patient should be evaluated in procedure selection. In clinical application, patient-specific evaluations and individualized considerations are essential for initialize the therapeutic strategy and decision making.

ABSTRACT

Objective To explore the association between post-stroke blood pressure and collaterals and functional outcome in acute ischemic stroke (AIS) patients with large vessel occlusion/stenosis.Methods Consecutive AIS patients with large vessel occlusion/stenosis who had symptom onset within 6 hours in Huashan Hospital from July 2011 to October 2017 were retrospectively recruited and enrolled.Collaterals were analyzed through CT perfusion imaging.And all the patients were followed up for 3 months.And the association between baseline blood pressure,collaterals and outcomes was analyzed using multivariate linear and Logistic models.A total of 126 patients were enrolled for multivariate Logistic and linear regression analysis.Results Multivariate Logistic regression analysis revealed that with every increment of 10 mmHg (1 mmHg =0.133 kPa) systolic blood pressure,the odds of poor functional outcome increased by 20% (unadjusted OR =1.20,95% CI 1.02-1.42,P =0.03).After adjusting for age and sex,the odds increased by 21% (OR =1.21,95% CI 1.01-1.46,P =0.04).However,no statistical significance was shown after multivariate adjustment (OR--1.02,95% CI 0.99-1.05,P =0.06).Multivariate linear regression analysis demonstrated that diastolic blood pressure (DBP) was negatively associated with the volume of hypoperfused and severely hypoperfused lesion.With every increment of 10 mmHg DBP,the volume of delay time (DT) > 6 s lesion downsized by 7.6 ml (unstandardized coefficient -7.56,95% CI-14.89--0.24,P =0.04).The DT >6 s/DT >3 s ratio was also decreased with the elevation of DBP (unstandardized coefficient-0.03,95 % CI-0.06--0.01,P =0.01).Conclusions For AIS patients,though higher DBP seems to be associated with better collaterals,it may still relate with poor functional outcome.

ABSTRACT

Objective@#To analyze the influence of growing experience on non-heterosexual orientation among male college students.@*Methods@#From October to November in 2015, a total of 2 535 male students from 96 classes in 14 colleges/departments were recruited from two colleges that participated in the experimental work of AIDS prevention by cluster random sampling method. A structured questionnaire was administered in this study, including general demographic information, growing experience and Kinsey scale (to evaluate sexual orientation). Out of 2 500 questionnaires distributed in this study, 2 332 effective copies were withdrew, with the effective rate at 93.3%. Chi square test was used to analyze the differences of non-heterosexual orientation among the individuals with different social demographic characteristics. Multivariate logistic regression model was used to analyze the influencing factors of non-heterosexual orientation.@*Results@#Among the 2 332 individuals, the proportion of self-reported non-heterosexual was 6.2% (144).The proportions of male students who identify as non-heterosexual from freshman to junior year were 5.2%(63/1216),6.9%(65/941),11.7%(13/111) and 4.7%(3/64), respectively (χ2=9.06,P=0.029). Compared with the individuals of very good relationship with parents, those with bad relationship (OR=3.3, 95%CI: 1.7-6.5) and general relationship (OR=1.7, 95%CI: 1.0-2.9) with parents had a higher risk of non-heterosexual orientation, respectively. Those encountered sexual assault had a higher risk of non-heterosexual orientation than those without encountered sexual assault (OR=5.9, 95%CI: 3.2-10.9).@*Conclusions@#This study reported a high proportion of self-reported non-heterosexual among college male students in Nanjing, and highlighted the importance of targeting students with poor parental relationships and who subjected to sexually abused.

ABSTRACT

Objective@#To explore the protective effect of Tongjingling (TJL) against sperm DNA damage and oxidative stress in the rat model of experimental varicocele (EVC).@*METHODS@#We randomly divided 75 Wistar male rats into five groups of equal number: sham operation, EVC model, high-dose TJL, mid-dose TJL, and low-dose TJL. The EVC model was established in the rats by partial ligation of the left renal vein, followed by 8 weeks of medication from the 4th week after modeling. Then we observed the general status of the rats, detected the sperm DNA fragmentation index (DFI) in the epididymis by sperm chromatin structure assay (SCSA), and measured the content of hydroperoxide (H2O2) and the activities of catalase (CAT) and superoxide dismutase (SOD) in the testis by colorimetry.@*RESULTS@#Compared with the sham operation group, the EVC models showed significantly increased sperm DFI in the epididymis (P <0.01) and elevated level of H2O2 and activities of CAT and SOD in the testis (P <0.01). In comparison with the EVC models, the rats of the TJL groups exhibited remarkably reduced sperm DFI and H2O2 content, but increased activities of SOD and CAT.@*CONCLUSIONS@#TJL can improve sperm DNA integrity by increasing the activities of SOD and CAT and reducing the H2O2 level and hence oxidative stress in the testis tissue.

ABSTRACT

Objective To construct the molecular transmission networks of HIV-1 CRF01 AE strains circulating in China and to analyze their characteristics. Methods Sequences of the pol genes of Chinese CRF01 AE strains were downloaded from Los Alamos database and the related demographic informa-tion was checked. Transmission networks were created by four steps,including phylogenetic tree construc-tion,transmission cluster extraction,minimum genetic distance identification and network visualization. Chi-square test was performed to analyze the differences in the distribution of different populations in the networks and the differences in the distribution of subjects with different degrees among different sub-populations. De-scriptive analysis was used to investigate the transmission links between sub-populations and various regions. Results The 2 419 sequences constituted 250 separate networks including 847 nodes and 610 edges. The number of subjects covered by different networks ranged from 2 to 25. Subjects with degree ≥2 represented only 26. 4%(224 / 847)of network-individuals,but were connected with 66. 5%(563 / 847)of all network-individuals. There were 37. 6%(669 / 1 781)of men who have sex with men(MSM),28. 4%(102 / 359) of heterosexual men,16. 1%(10 / 62)of intravenous drug users(IDUs)and 30. 4%(66 / 217)of hetero-sexual women involved in the networks(χ2 =23. 774,P﹤0. 001). The percentage of subjects with degree ≥2 was high in MSM(10. 8% ,193 / 1 781)compared to that in heterosexual men(5. 6% ,20 / 359)(P =0. 002)and heterosexual women(4. 6% ,10 / 217)(P=0. 004). Of the 669 MSM in the networks,95. 5%(639 / 669)linked to other MSM and only 2. 4% (16 / 669)linked to heterosexual women. However, 15. 1%(10 / 66)of the heterosexual women in the networks linked to MSM. Of the heterosexual men in the networks,35. 3%(36 / 102)linked to heterosexual women,9. 8%(10 / 102)linked to MSM. Of the sub-jects in the networks,20. 9%(177 / 847)linked to other regions' individuals. Conclusion The super-spreaders played an important role in the molecular transmission networks of HIV-1 CRF01 AE strains even though they were in a minority. The transmission of HIV-1 CRF01 AE strains between sub-populations and various regions was complicated and active.

ABSTRACT

To observe the mid- and long-term result of intentional coverage of celiac artery in thoracic endovascular aortic repair (TEVAR) surgery for aortic dissection.
 Methods: We retrospectively analyzed 21 cases who received TEVAR with celiac artery coverage during the operation. The existence of collaterals between celiac artery (CA) and superior mesenteric artery (SMA) was confirmed by preoperative CT angiography (CTA) or digital substract angiography (DSA) for each patient. We used the stent-graft precisely above the orifice of SMA. Follow-ups were carried out at 2 weeks, 1 month, 3 months, 6 months, 1 year after the operation, and once per year thereafter.
 Results: No signs of visceral artery ischemic syptoms such as liver dysfunction, abdominal pain or distention were observed after the operation. There was no signs of spinal cord ischemia (SCI). Seven cases showed type II endoleak upon completion DSA but stopped automatically within 3 months. CTA in follow-ups showed thrombosis formation in false lumen.
