Objective:This study sought to investigate the feasibility, anatomical indications and operating points of transcatheter aortic valve replacement (TAVR) procedure in the treatment of pure aortic regurgitation (AR).Methods:The medical records of 4 elderly patients with pure AR who were treated in the cardiology department, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from March 2020 to March 2021 were retrospectively analyzed. All patients were implanted with self-expandable valve stents via peripheral artery approach for TAVR treatment. The feasibility, anatomical indications and key points of TAVR were analyzed.Results:The 4 patients with pure AR who were carefully screened had an average age of 66 years, and all achieved TAVR treatment success without serious perioperative complications and death. Postoperative examination and follow-up data showed that cardiac functions and cardiac remodeling indexes were significantly improved.Conclusions:This exploratory study shows that TAVR is technically feasible and effective treatment option for selected elderly patients with native pure AR, which is worthy of further study.
RÉSUMÉ
In the paper, it is introduced professor's recognition on the pathogenesis and professor's experience in the treatment of the motor impairment of the trunk after stroke. Professorbelieves that the motor impairment of the trunk after stroke is the essential factor affecting the rehabilitation in stroke. The motor impairment of the trunk after stroke results from brain marrow damage and spiritual impairment. Hence, regaining the consciousness and promoting the circulation of the governor vessel are the basic principles of the treatment, named regulating the mind and controlling, benefitingand warming, tonifying the kidney and filling up the essence, and promoting the circulation of the governor vessel. Those four therapeutic methods are equally important. Acupuncture, moxibusiton and herbal medicine are applied in combination in the treatment. Additionally, the psychotherapy and rehabilitation are the accessory therapies.

Objective To investigate the relationship between microalbuminuria to estimated glomerular filtration rate (mALB/GFR) ratio and incidence of contrast induced nephropathy (CIN) after underwent percutaneous coronary intervention (PCI). Between March 2010 to August 2011, a total of 137 patients who underwent PCI were selected. Anthropometric measures, lipid profiles, fasting blood glucose, CRP, base creatinine and microalbuminuria were measured before operation. Glomerular filtration rate was calculated by MDRD formula. Contrast volume (CV) was recorded after the operation for each patient. Serum creatinine was measured 24 h, 48 h, 72 h after operation, respectively. CIN was defined as an increase in serum creatinine levels of 25% or 44 μmol/L or more from baseline within 72 h after PCI. All patients were divided into group A (CIN group) and group B (No CIN group). Results Eighteen (13.1%) patients developed CIN(group A). The others were group B (no CIN group). The level of CRP, base creatinine, microalbuminuria and mALB/GFR in group A were significantly higher than that in group B ( P < 0 . 01 ) . GFR in group A was lower than that in group B (P < 0.05). Logistic regression analysis indicated that the level of base creatinine , microalbuminuria GFR and mALB/GFR were independent risk factors of CIN occurrence (P < 0.05). The receiver-operator characteristic curve analysis indicated that a mALB/ GFR ratio of 1.17 was a fair discriminator for CIN,and sensitivity were 94.1%, specifity were 72.5%. Conclusion A mALB/ GFR ratio was a independent predictor of CIN after PCI.

This article presents concepts related to Rho/ROCK signal pathway, and its effect on axonal regeneration and the mechanism of its action to provide a theoretical basis for the inhibition of this signal pathway to promote neural regeneration and functional recovery and further for clinical treatment of nerve injuries and other nervous system diseases.
