Objective: To investigate whether embryonic soluble human leukocyte antigen-G (sHLA-G) could be a noninvasive marker for embryo competency in assisted reproductive technology (ART), which is still controversial due to the different detection assays used and the different culture conditions in laboratories. Study Design: Based on the standardization of IVF procedures and the embryo culture condition, a total of 205 embryo culture supernatants (ESs) from 92 ART cycles were evaluated for sHLA-G contents by chemiluminescent ELISA assay. Results: sHLA-G presence could be detected in 30.7% of the ESs tested. In the cycles where at least one of the embryos transferred was positive for sHLA-G, 51.9% of patients (27/52) achieved a clinical pregnancy. In cycles where none of the embryos transferred secreted detectable amounts of sHLA-G, the pregnancy rate was only 30.0% (12/40, p<0.05). The implantation rate in sHLA-G-positive cycles was also significantly higher (31.5%) than that in sHLA-G-negative cycles (14.9%, p<0.05). Conclusion: The results suggested sHLA-G in ESs as a potential marker of embryo competency in ART programs for the Chinese population. © Journal of Reproductive Medicine ®, Inc.

BACKGROUND: Treatment methods for defects of fingertip skin or soft tissue combined with partial deletion bed include the phalanx shortening or flap coverage of wounds, each with shortcomings. OBJECTIVE: To investigate the efficacy of repairing finger nail bed defects by different treatments in one stage, and to evaluate the functional recovery of nail beds comprehensively. METHODS: From December 2002 to February 2009, 51 fingers with nail bed defects in 40 patients (11 thumbs, 22 index fingers, 14 middle fingers, 4 ring fingers) were repaired. Under the situation that the periosteum exist, when the area of nail bed defect area was less than one third of the nail, the graft was taken from the same finger. If the area of nail bed defects were larger than one third of the nail or two nail bed defects, the grafts were taken from the nail beds of 1st or 2nd toes. Under the situation that the periosteum nonexist, when the area of nail bed defect area was less than one half and more than one third of the nail, the split tissue flap was transferred from the same finger. The finger appearance and functions were observed in the follow-up. RESULTS AND CONCLUSION: All patients were followed up from 1 month to 2 years with an average of 6 months, 86.3% grafts survived very well, no pain, no infection and obvious deformed growth of nail were found. It revealed that using different treatment to repair nail bed defect is available. The grafted nail can grow in good appearance, and finger can act in good function.
