Letters to the Editors

Regarding the article entitled: “No-scalpel vasectomy outside China” by Drs Bing XU and Wei-Dong HUANG of the Chongqing Li Shun-Qiang Andrology Hospital, I would like to draw the attention of readers of the joumal to an excellent training film made by Dr LI Shun-Qiang (Chengdu) with the funding support of WHO and AVSC. This film, entitled “No-scalpel Vasectomy”, illustrates the key points in the procedure and shows Dr Li‘s preferred technique. The film occupies 9-10 minutes and is available in PAL and SECAM format. It won an award from the British Surgical Society for its high quality and clarity.     

Immunosuppression—Back to the Future

During the 1950s work on bone marrow transplantation for patients with aplastic anemia led to the search for means other than total body irradiation to prevent rejection of the bone marrow allograft. At the same time, it had become clear that lymphocyte proliferation was a prominent feature of the immune response against all kinds of antigens, including skin allografts. These two factors led us to test various chemical agents known to block the proliferation of leukemic lymphocytes for their ability to inhibit the immune response against soluble antigens and skin allografts. One compound, the antileukemic drug 6-mercaptopurine, was effective in both test systems. This drug and its sister compound azathioprine (which is mercaptopurine with an imidizaole ring instead of a sulfhydryl group on carbon 6) were soon applied to human allografting and the treatment of autoimmune diseases.     

Congratulations to the publication of CJIIT

It is my great pleasure and honor to give my congratulations to the publication of Chinese Journal of Interventional Imaging and Therapy. I have always been greatly impressed by the recent rapid progress in the economy of China. The role of the Chinese Government in the political world has become greater and greater. There is no doubt that China will become one of the most influential nations in the medical world also, in particular in the field of interventional imaging and therapy. My personal interest is how the traditional Chinese medicine becomes harmonized with the modern western medicine.     

Parathyroid resistance to FGF23 in kidney transplant recipients: back to the past or ahead to the future?

Fibroblast growth factor 23 (FGF23) modulates the metabolism of minerals and vitamin D. In chronic kidney disease (CKD), this process is disturbed owing to decreased parathyroid expression of FGF23's receptor complex Klotho-FGF receptor 1. In this issue, Krajisnik and colleagues demonstrate that similar alterations occur in parathyroid glands from kidney transplant recipients in association with a decline in allograft function. Is it possible that these data can be extrapolated to general early-stage CKD patients?     

Editorial Commentary: To Boldy Go…to the Back of the Glenoid: Bone is the Key to Success

Risk factors of failure after arthroscopic posterior shoulder stabilization are not well understood. Careful attention to anatomy may be the key to helping patients understand their risk of failure after surgery. Posterior stabilization may be even more sensitive to small amounts of bone loss than is anterior stabilization.
