Objective To evaluate the method for vaginal treconstruction with muscle sparing verti-cle rectus abdominis myocutaneous flap(MS-VRAM flap). Methods From September 2006 to April 2008, MS-VRAM flaps were used for vaginal reconstruction in 9 patients (20 to 35 years old), ancl all ca-ses were congenital absence of vagina. Before operation, the inferior epigastrie arteries were detected by the Doppler and the flaps based on the perforators ranged from 6 cm×20 cm. MS-VRAM flaps were ele-vated and then transferred to reconstruct the vagina. Results All 9 cases of MS-VRAM flaps survived completely. No complications occurred at donor site of abdominal wall. With 2-12 months' follow-up, the patients were satisfied with the results. Conclusion Despite technical difficulties in elevating the MS-VRAM flap, the flap is a good choice for vaginal reconstruction.

Objective To compare the perinipple round-block technique with the conventional periareolar round-block technique in areolar reduction operations.Methods A total of 37 patients who underwent areolar reduction operations in our department were randomly allocated into two groups:Group A (19 patients) received a conventional periareolar round-block technique,while group B (18 patients) through a new perinipple round-block technique.In the latter approach,an intraareolar donut of pigmented skin was deepithelialized,and the exposed areolar dermis was then telescoped inward and stretch-anchored to an imaginary circular line situated beneath the breast skin areola junction.The roundblock technique was then utilized to approximate the skin edges,resulting in a minimal scar,totally inconspicuous,confined to the immediate perinipple area.The operative time,perioperative complications,scars,absorption time of the skin folds,the sensation of the nipple-areolar complex and the patients' satisfaction were compared between the two groups.Results The mean operative time of group A and group B was 40.5 min and 45.8 min,respectively (P<0.05).No perioperative complications were found in these two groups.No patient had experienced permanent nipple sensory changes.The skin folds absorption time of group A was 4.34 months,while the time of group B was 8.78 months (P<0.01).The perinipple round-block technique produced a more inconspicuous scar with a better aesthetic results.Conclusions The traditional periareolar round-block technique leaves a sharply demarcated areola by a circular scar which has a totally unnatural and artificial look.As for the perinipple round-block technique,the incision as well as any residual cutaneous wrinkling or puckering is well concealed by the dome of the nipple and the areolar,but it needs a longer skin folds absorption time.

Objective By culturing the osteoclasts together with the osteoblasts directly to investigate the effect of osteoblasts on the formation of mature osteoclasts.Methods The bone marrow mononuclear cells of rats were treated with 30?g/L M-CSF and 50?g/L RANKL and cultured for 6 days.Subsequently,the primary osteoblasts which were of the same quantity as the osteoclasts were co-cultured directly.In the co-culture system,we added the liquid containing 1,25-(OH)2D3 1?10-8mol/L and PGE2 1?10-6mol/L.The morphological observation,TRAP staining and pit staining were adopted to identify osteoclasts.Results When the osteoclasts were co-cultured with primary osteoblasts,the growth of osteoblasts had more preponderances.After staining,we could see more osteoblasts than osteoclasts.Conclusion The relationship between osteoblasts and osteoclasts is related to the relative quantities of the two cells.When osteoblasts outnumber osteoclasts,osteoblasts would inhibit the formation and differentiation of osteoclasts.

It has been 50 years since the discovery of thyrotropin receptor autoantibody (TRAb). Advances in the knowledge of thyrotropin receptor ( TSHR) structure and function, combined with the elucidation of TSHR signaling and TSHR-autoantibody interaction have greatly facilitated our understanding of TRAb and their clinical applications. Measurement of TRAb activity plays an important role in the diagnosis of Graves' disease ( GD) and Graves' opthalmopathy. It has also been well recognized that TRAb is an effective predictor of GD relapse or remission after antithyroid drug and radioactive iodine treatment. TRAb test is of particular help in pregnant women and lactating mothers with recent iodine load, where radioactive iodine or technetium tests are contraindicated. In addition, it is useful in the diagnosis and differential diagnosis of fetal and neonatal hyperthyroidism as well as some rare forms of thyrotoxicosis in clinical practice. Accumulating evidence also indicates the possible correlation between thyroid cancer occurring in GD patients with positive TRAb and adverse outcomes. However, further innovation and standardization of TRAb tests are required to help pave the way for clinical applications.

[Summary] Lifestyle intervention is one of the important strategies for the prevention of type 2 diabetes. Recently, caloric restriction regimen has become a hot topic as one of the cornerstone of lifestyle intervention. The alternate day fasting regimen is simple, and increases the patient compliance. Both daily calorie restriction and alternate day fasting regimen can reduce body-weight significantly in pre-diabetes subjects, and reduce the visceral fat mass and the fasting insulin levels, and improve the insulin sensitivity, as well as maintain the lean mass, though the effect on fasting blood glucose was not significant. Nevertheless, the most recent studies have demonstrated that daily calorie restriction,in particular, alternate day fasting regimens can be effective in individuals with pre-diebates in order to prevent type 2 diabetes.
