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:To evaluate the effect of L-carnitine on serum total level of homocysteine (tHcy) in patients undergoing maintenance hemodialysis. METHODS: 60 patients undergoing maintenance hemodialysis were randomly divided into two groups (treatment group and control group): the patients in the treatment group were injected i.v. with 1.0 g of L-carnitine for 12 weeks,and those in the control group were injected i.v. with 5 mL normal saline for 12 weeks. Meanwhile,the healthy people were involved as normal control group(n=20). tHcy was detected by ELISA method;the fasting insulin was detected by radio-immunity method. Fasting blood glucose,total cholesterol,triglyeride,HDL and LDL were detected by routine method. The reciprocal of the multiplication product between fasting blood glucose and insulin concentration were computed as insulin sensitivity index(ISI). RESULTS: After treatment for 12 weeks,the treatment group showed increased ISI but significantly reduced tHcy(P
