ABSTRACT

To explore the correlation between single nucleotide polymorphisms (SNPs) of hormone receptor gene or other related genes and axillary osmidrosis (AO).
 Methods: Whole blood samples of 219 patients with AO and 159 normal people were collected, and their genomic DNA was extracted. SNPs of 49 selected gene loci were detected and analyzed by using matrix-assisted laser analysis and ionization time of flight mass spectrometry and other related technologies.
 Results: There were significant differences in SNPs at rs1256061 of estrogen receptor β gene and rs17822931, rs16945916 and rs62058521 in ABCC11 gene between the AO patients and normal people (all P<0.01). 81.1% of patients with AO carried G allele at rs1256061, while only 63.2% of normal people carried G allele; 96.3% of patients with AO carried G allele at rs17822931, while only 4.4% of the normal people carried G allele; 28.6% of the patients with armpit odor carried the G allele of rs16945916, while only 0.6% of the normal people carried G allele; 28.0% of patients with AO carried G allele at rs62058521, while only 0.6% of the normal people carried G allele.
 Conclusion: SNPs of rs1256061 at the locus of estrogen receptor gene are correlated with the pathogenesis of AO, while SNPs at multiple loci (rs16945916, rs62058521 and rs17822931) in ABCC11 gene are correlated with the pathogenesis of AO.

ABSTRACT

As a kind of neurotoxin causing muscle paralysis from Clostridium botulinum, the botulinum toxin A is currently used in different clinical aspects, especially in the facial cosmetic. Compared with the traditional surgical methods, the botulinum toxin injection is minimally invasive and safe, favored by more beauty seekers and with better efficacy. However, factors, such as injection dose, operation skills, and anatomical variation, may result in side effects during the operation, including poor injection experience and drug dispersion.

ABSTRACT

OBJECTIVE@#To explore the safe method with anhydrous ethanol injection in the treatment of venous malformation.
@*METHODS@#A total of 96 patients with venous malformation were conducted anhydrous ethanol injection for 245 times through percutaneous puncture by three-point method. The complications were observed. In animal experiment, according to the different concentrations of anhydrous ethanol injection, rats were divided into an anhydrous ethanol group, a 75% ethanol group, a 50% ethanol group and a 25% ethanol group (n=5 in each group), and the damage of vessels after ethanol injection was observed.
@*RESULTS@#The successful rate for three-point ethanol injection was 88%. The incidence for both skin ulcer and numbness was 0.9% without severe complications in lung and heart. In the animal experiments, the entire vessel wall including outer membrane was damaged in the anhydrous ethanol group. Part of vessel walls, including the inner membrane and muscle layer, were damaged in both the 75% ethanol group and the 50% ethanol group. However, there was no damage in the vessels in the 25% ethanol group.
@*CONCLUSION@#With the decrease in ethanol concentration, the vascular damage is decreased and eventually disappeared. Three-point anhydrous ethanol injection is safe and effective.

ABSTRACT

BACKGROUND: Thoracodorsal artery perforator flap can relieve damage to donor site and avoid bulk in the recipient site,but dissociation of perforating branch took time.Some one believed that it should be done by very experienced physicians and some muscle tissues should be reserved.OBJECTIVE: To investigate the method,effectiveness and clinical application of improved latissimus dorsi flap based on perforator flap conception for reconstruction of soft tissue defects of lower extremity.METHODS: A total of 17 patients needing skin flap transplantation were selected.12 latissimus dorsi musculocutaneous/muscle flaps,3 latissimus dorsi flaps with a few muscle and 2 double-leaf segmental latissimus dorsi compound flaps were designed based on perforator flap conception.According to the territory of latissimus dorsi musculocutaneous flap,a skin paddle in which anterior underlying muscle and main perforator was designed,extend about to the anterior edge of the latissimus dorsi muscle.An additional latissimus dorsi muscle flap was selected for soft tissue enlargement if necessary.Sometimes,double-leaf segmental latissimus dorsi musculocutaneous/muscle flap,including one muscle-sparing latissimus dorsi musculocutaneous flap and the other segmental latissimus dorsi muscle flap nourished by the lateral branches of the thoracodorsal vessels was selected to repair two adjacent defects.The harvested tissue area ranged from 12 cm×8 cm to 28 cm×17 cm.Survival state of skin flap,together with shape and function of donor site and recipient site of skin flap were observed.RESULTS AND CONCLUSION: Following skin flap transplantation,one case developed vascular crisis that was relieved following re-exploration for vessel anastomosis.All skin flap survived.Second-stage skin grafting was done on one muscle flap wound.All donor sites were sutured directly.After a follow-up of 3 to 18 months in 15 cases,only two cases received two-stage plastic operation because bulky flaps brought some trouble in wearing shoes.Improved latissimus dorsi flap based on perforator flap conception can reduce damage to the donor site and the receipt area bulk.Double-leaf segmental latissimus dorsi compound flaps can repair both heel and toe wound.The versatile latissimus dorsi flap designed using thoracodorsal artery perforator flap conception is an ideal flap for repairing widespread soft tissue defects in the lower extremity.

ABSTRACT

BACKGROUND:Non-hematopoietic cell of mesenchymal stem cells (MSCs) or mesenchymal progenitor cells can differentiate into bone,cartilage,muscle,tendon,fat and bone marrow matrix in vivo and in vitro,thus becoming very valuable seed cells source in the field of tissue engineering.OBJECTIVE:To construct the tissue engineered tendon withⅠcollagen-polyglycolic acid as a scaffold and bone marrow MSCs as seed cells,and to observe the effect of tissue engineered tendon on repairing achilles tendon defects. DESIGN,TIME AND SETTING:Randomized controlled animal experiment was performed in the Xiangya Medical College of Central South University in 2003.MATERIALS:Healthy adult rabbits,irrespective of genders,weighing 1.5-2.5 kg,were offered by Animal Center of Xiangya Medical College,Central South University. Polyglycolic acid were purchased from Shandong Weigao Group Kanglida Medical Products Co.,Ltd (KLD Medical).SD rats were sourced from Department of Experimental Animals,Central South University.METHODS:Rabbit bone marrow was extracted to harvest MSCs with centrrfugation and adherence method,then bone marrow MSCs were isolated and amplified. Tail tendon was extracted from SD rats and prepared into type Ⅰ collagen solution,which was mixed and suture cultured with polyglycolic acid to construct collagen-polyglycolic acid scaffold. Other bone marrow MSCs,which were not induced in vitro,were incubated on collagen-polyglycolic acid scaffold to construct tissue engineered rabbit tendon models,with those without cells serving as controls. Thirty rabbit angle skins were cut open to separate tendon and produce a 3-cm defect. Fifteen rats in the experiment group was repaired with tissue engineered tendon,which was previously prepared with autologous bone marrow MSCs,while fifteen rats in the control group was given Ⅰ collagen-polyglycolic acid scaffold.MAIN OUTCOME MEASURES:Effect of tissue engineered tendon on repairing achilles tendon defects in rabbit.RESULTS:No matter whether contains autologous bone marrow MSCs,type I collagen-polyglycolic acid scaffold transplanted into animals exhibited column gel shape by general observation. At 4 weeks following transplantation,cordlike tissues were seen in the transplantation site,polyglycolic acid suture was degraded. At 8 weeks,the tissue engineered tendon tissues were cordlike shaped,white,lustrous and dense. They were well connected with receptor tendon tissues in the experiment group,without adhesion to peripheral tissues. In the control group,the tissues were slender and adhered to peripheral tissues. CONCLUSION:Using typeⅠ collagen-polyglycolic acid as a scaffold and bone marrow MSCs as seed cells,tissue engineered tendon can dramatically promote the repair of achilles tendon defects.

ABSTRACT

Objective To study the clinica features, diagnosis and surgical treatment of simple and complex macromastia. Methods The clinical and pathological data of 21 patients with macromastia in our hospital from 1990 to 2000 were analysed retrospectively. Simple macromastia in 16 patients with 29 breasts, complex macromastia in 5 patients with 8 breasts. Results The average age of patients was 23 years old. All the 21 patients were treated surgically. Among the 5 patients with complex macromastia, subcutaneous mastectomy and reconstruction were performed on 2 patients with breast fibroadenomatosis; of the 2 patients with giant fibroadenoma, one underwent tumor excision, the others were subjected to tumor excision with reduction mammaplasty; the last one with breast fibrous disease, selective partial breast excision and reduction mammaplasty was performed. All the patients had satisfactory mammary appearance and hadn't recurrrence of the breast disease in follow up period. Conclusions (1) Macromastia often happens in the adolescent and young women. (2) It is necessary to do biopsy during operation for distinguishing the simple from the complex macromastia. (3) The treatment for simple macromatia is reduction mammaplasty; for complex macromatia is dissection of the disease area completely and redution mammaplasty simultaneously. For macromastia with fibroadenomatosis, subcutaneous mastectomy with reconstruction can prevent tumor recurrence and get better mammary appearance.

ABSTRACT

Objective To investigate the biocompatibility between collagen- polyglycolic acid (PGA) and bone marrow mesenchymal stem cells (MSCs) in vitro to provide some experimental basis for further study in tendon tissue engineering. Methods MSCs were isolated, cultured and characterized. In the experimental group the MSCs were cultured in DMEM containing type-I collagen and PGA suture, and in the control group the MSCs were cultured in DMEM. The cell growth was compared between the two groups, and the cell ultramicroscopic structure of experimental group was observed. Results MSCs grew well in the collagen-PGA scaffold, and 2 weeks after incubation they still kept secretion potential and more than cell 89% vitality, which were not significantly different compared with the control group. There is no statistical difference in the MSCs count in the experimental group during 2 weeks culture, while in the control group MSCs began to proliferate at the 4th day after culture. Conclusion Collagen-PGA has a good biocompatibility with mesenchymal stem cells. It is possible to fabricate a tissue-engineered tendon in vitro using mesenchymal stem cells as seed cells and collagen-PGA as scaffold.
