OBJECTIVETo introduce an operation for fingertip reconstruction.

METHODSThe vascularity of the reverse dorsal island flap is augmented by performing an arteriovenous anastomosis between the dorsal vein in the flap and a digital artery at the fingertip. The flap was used in ten patients for reconstruction of their fingertip defects.

RESULTSAll the ten flaps survived and the appearance was good.

CONCLUSIONThe method is easy except for the necessity of performing standard microvascular surgery. The flap is a good option for repairing fingertip defects.

OBJECTIVES: To explore the identification method of full sibling between two males with microdeletion and mutation of Y chromosome. METHODS: DNA were extracted from two samples. The type testing of Y-STR and autosomal STR were performed. Full sibling between two individuals was calculated by IBS, ITO and discriminant functions methods. RESULTS: There were 2 loci mutations existed in 33 Y-STR loci and one of the two samples had 19 loci deletions. The IBS of two samples was 53 and greater than the threshold which was 42; FSI was 1.36×10¹⁶ and far greater than 19. The discriminant function of full sibling-unrelated individual D_FS2 was greater than D_R2, which meant the two individuals tend to be full sibling. CONCLUSIONS The methods of IBS, ITO and discriminant functions of full sibling-unrelated individual can be used comprehensively to provide more reliable expert opinion in microdeletion and mutation of Y chromosome in full sibling identification.

A good integration of dental implants and the surrounding soft tissue is essential to ensure the long-term effect of implant. In this review, we summarized the research progress of peri-implant soft tissue integration of dental titanium implants, with emphasis on the modification of the gingival interface of implants based on immune microenvironment regulation. This method influences the immune response around the implant by promoting the surface properties of implants, so as to enhance the peri-implant soft tissue integration. The purpose of this review is to provide reference for the related research and clinical application in the field of dental implantation.
