Objective To explore the indication of implant prosthesis immediately after removing polyacrylamide hydrogel for augmentation mammaplasty. Methods MRI and pathologic examinations were made in 226 patients with the postoperative complications of augmentation mammaplasty by injecting polyacrylamide hydrogel and with the specific conditions in operation to analyze the possibility of implant prosthesis while removing polyacrylamide hydrogel. Based on MRI examination, physical examination and specific conditions in operation, we chosen 61 cases who requested for implant prosthesis while removing polyacrylamide hydrogel. Results The patients who did the operation for simply removing polyacrylamide hydrogel recovered well and symptoms such as pain, sclerosis, mass and others disappeared almostly; the patients who did implanting at the same time were satisfied with the breast shape and had no side-effect occured. Conclusion With MRI examination, physical examination and specific conditions in operation, it can achive good effects to do implanting immediately after removing polyacrylamide hydrogel for those suitable and willing to implant prosthesis.

A 30-year-old woman presented with a 5-year history of recurrent nodular lesions in the left subaxillary region,which had rapidly grown for 7 weeks.Five years prior to the presentation,she received breast conservation surgery and radiotherapy for left breast cancer,thereafter,chronic radiation dermatitis developed in the left subaxillary region.Two years after the operation,three soybean-sized bright red nodules appeared in the lesions of radiation dermatitis,and slowly enlarged.Subsequently,the nodules were resected,but a local recurrence was observed 3 weeks after the resection.The recurrent masses underwent accelerated growth during her pregnancy,and the growth was obviously inhibited after the termination of pregnancy.Physical examination revealed a quasi-elliptic,dark or bright red plaque measuring about 18 cm × 14 cm with a smooth surface in left subaxillary region,and in the center of the plaque was a bright red,hemispheric,elevated lesion measuring 10 cm × 9 cm × 5 cm with erosions or pitchy crusts on the surface.Histopathology of the lesions showed that the tumor was located in the dermis and consisted of densely packed uniform spindle-shaped cells arranged in a characteristic storiform or whirlpool pattern.Some cell nuclei showed atypia,and few mitoses were observed.In some parts of the lesion,tumor cells were arranged in a herringbone pattern.Immunohistochemistry revealed that the tumor cells stained positive for vimentin(strongly)and actin(weakly),but negative for CD34.Based on these findings,a diagnosis of postradiation dermatofibrosarcoma protuberans(fibrosarcoma type)was made.

Objective To evaluate the effects of pingangmycin and dexamethasonum injected synchronously in the treatment of hemangioma in maxillofacial regions. Methods A total of 83 patients with hemangioma in maxillofacial regions between September 1996 and March 2004 were reviewed. The age of the patients was from 3 months to 50 years old. The sizes of the lesions varied from 1cm?1cm to 6cm?9cm. Injection should be accorded to size of the tumor, local appearance and patients' age. Injection might be repeated in every 5~10 days, totally 4~6 times. Results All cases were followed up from 8 to 36 months. The recovery rate was 95.18%, and the total effective rate was 100%. Conclusion This method is a simple, safe and effective therapy of hemangioma in maxillofacial regions.

Objective To introduce and evaluate an improved technique of vertical mammaplasty for correction of severe breast ptosis. Methods Vertical mammaplasty that was first reported by Ma-deleine Lejour in Brussels is a technique that uses adjustable markings, an upper pedicle for the areola, and a central breast reduction with lower skin undermining. To shorten vertical scar, it was important to locate new nipple position and move up new inframammary fold. The shape of the breast was crea-ted by suturing the gland and did not rely on the skin. No scar was produced in submammary fold. Re-sults 36 cases were treated with vertical mammaplasty in our department since August 1999. The shape of the new breast was satisfactory in all patients after 3-24 months following-up. Areora necro-sis was not found in all the cases. Conclusion The vertical mammaplasty is an optical technique for correction of severe breast ptosis, Stable results are produced because the gland is strongly sutured.

Objective To evaluate mammaplasty for repairing the serious breast asymmetry.Methods Different mammaplasty was used to repair 38 cases of breast asymmetry,including 13 cases of unilateral breast augmentation,10 cases of breast reduction after different volume resection on each side,4 cases of unilateral partial breast resection,5 cases of breast reduction on one side and breast suspended on another side,4 cases of breast suspension on one side and augmentation on the other side,and 2 cases of only suspension on unilateral breast.The 38 cases were followed up for 3 to 12 months postoperatively to evaluate the results.Results One case had slight ptosis in half a year after breast suspension.Apart from mentioned above,the rest of 11 had favorable and satisfactory results.Conclusions The serious breast asymmetry deformities should be corrected with the method of the simple and minimum injuries to make the best result.

Objective To investigate the value of surgical biopsy with guidance of indwelling wire through stereotactic puncture in the diagnosis of occult breast cancer (OBC) and the clinical usage. Method Surgical biopsy was performed on 22 patients with suspected nonpalpable breast lesions. ResultsSurgical biopsy, including localization and resection of the lesion, under the guidance of a guide wire was successful with single procedure for all 22 lesions. The accuracy of qualitative diagnosis was 100%. Pathological examination showed malignant in 9 lesions and benign in 13 lesions. ConclusionThe surgical biopsy with the guidance of indwelling wire through stereotactic puncture is valuable technigue for the diagnosis of occult breast lesions.

Objective To explore the teaching effects of physiology lectures and students' attitude to lectures,their suggestions for contents,forms and other aspects of lectures.Methods Random sampling questionnaire survey was conducted among 500 students of 2008 grade and 2009 grade in Xiangya medical school of central south university.The percentage of the option in the questionnaire was calculated and the findings were directly described.Results All students thought that physiology lectures were necessary.Teachers should arrange lectures which students were interested in,pay attention to inspire thinking and enhance teacher-student interaction.67.6％ of students thought that the knowledge learned from lectures can be used in expanding scientific thinking.Conclusions The lectures are popular among most students,playing an important role in cultivating students' ability of strict scientific thinking.

Salvia miltorrhiza Bge is a medicinal herb in traditional Chinese medicines. Until recently, dozens of compound ingredients with medicinal properties have been identified from S. miltorrhiza. Proteome analysis on medicinal ingredients synthesis mechanisms could provide a theoretical basis for S. miltorrhiza genetic improve-ment. In this study, a S. miltorrhiza specific protein/peptide sequence database was constructed using Illumina high-throughput transcriptome sequencing data of multiple types of S. miltorrhiza tissues. The database could act as a key component to carry out the proteome analysis in S. miltorrhiza.

Objective To summarize the experience of the integrated treatment on mid-face ageing for better cosmetic results.Methods A total of 56 cases were treated.With using subciliary approaches,the orbicularis oculi was resected to expose the orbital septum,the orbital fat relieved and orbital septum reseted.Hyaluronic acid was injected to some patients with obvious nasolabial fold after operation.Results 56 cases were all followed up from 6 to 26 months (11.8 months on average) postoperatively.The flabby tissue had been tightened and all got better effects.Conclusions Various combination of technologies can be applied to reach the purpose of rejuvenation by correcting the volume abnormality,resetting the tissue,elevating reasonably,and filling the facial depression.

From August 2007 to January 2009 a total of 95 patients with complex renal calculi were treated with CT ( n = 32 ), X-ray ( n = 33 ) or ultrasound ( n = 30 ) guided percutaneous nephrostomy and ureteroscopic holmium laser lithotripsy respectively. The CT guided procedure had lower positioning time,positioning failure rate, complication rate and residual stone rate than those of X-ray and ultrasound localization, particularly had advantages in the stone clearance rate and complications rate ( all P ＜ 0. 05 ).CT guided localization can be chosen in the following conditions: higher kidney position, large staghorn calculi or renal pelvis stones without hydronephrosis, with congenital renal malformations or failure of ultrasound or X-ray localization.
