Objective To discuss the surgical techniques and efficacy of a new method of breast treatment of hypermastia. Methods From January 2009 to February 2011, a series of 15 patients underwent a new technique for reduction mammaplasty. This technique involved a superomedial pedicle nipple-areolar complex (NAC). Results In our series, the resection weight per breast was (522. 9±218.3) g and the new nipple-to-sternal-notch distance was (21.7± 1.74) cm postoperatively. Mean nipple elevation was 8. 5cm (range, 4-16 cm). There were no hematoma and partial or complete NAC necroses occurred in our series. Minimal wound dehiscence occurred in one case ( 6.7 % ). Thirteen patients were followed up for 6 to 18 months. NAC sensibilities were comparable before and after operation, and good breast shapes were produced in all cases. Conclusion The superomedial pedicle technique provides good results with respect to NAC viability and sensibility, breast contour and last superomedial fullness.

Human myiasis is caused by the parasitic maggots of flies. We report a case of nasal myiasis in a 37-year-old woman in Henan. The patient presented with nasal foreign-body sensation, nansal itching sneezing, snuffle and such allergic symptoms in nasal cavity. Based on maggots that were bowed from the right nasal cavity, a detailed endoscopic examination, sinus CT scan and identification of the maggot's species done by parapsychologists of the parasitology teaching and reseach section of the Zhengzhou University School of Medicine, the diagnosis of human nasal infestation by oestrus ovis was definited.

Objective:To study the mechanical properties of a new titanium alloy with lower elastic modulus for prosthodontic use.Methods:Samples of a newly developed Ti-Nb-Zr-Sn alloy with low elastic modulus were prepared.The microstructure,microhardness profile of the specimen cross section were measured by microhardness test meter and metallurgical microscope.Results:The data of the tensile strength(MPa),yield strength(MPa),elongation(%),elastic modulus(GPa) and microhardness(Hv)of Ti-Nb-Zr-Sn alloy were 681.7,410,6,42.1 and 453 respectively.The microstructure was with fine crystal grains.Conclusion: The microstructure and microhardness profile of the Ti-Nb-Zr-Sn alloy may meet the requirement for dental applications.

Objective To study a graft method of an acellular dermis composited with cultured human keratinocyte sheets,and investigate the outcomes of the composite graft on full-thickness wounds.Methods Using porcine skins,we prepared the acellular dermis and cultured human keratinocyte sheets in vitro.Athymic null mice were divided into the experimental group and the control group,the acellular xeno-dermis was implanted into the subcutaneous of the dorsal skin in experimental group,one week after the implantation the cultured keratinocyte sheets were grafted on the full-thickness defective area of the dorsal skin in the experimental group,in control group only implanted human keratinocyte sheet on the defective area wound,healing status was regular assessed,and biopsies for histological analysis and immunohistochemistry test were performed in post-operation.Results Compared with the control group,the appearance of wound coverage in the experimental group was better.Moreover,the histologic analysis revealed that fully differentiated epidermis,organized proliferated collagen fibers and significant reconstruction of epidermis-dermis junction were seen in the experimental group which lack of the acute immuno-rejection response.Conclusion As a kind of dermal substitutes,the acellular xeno-dermis can be compositely transplanted with cultured human keratinocyte sheet and can improve the quality of wound healing.
