Objective To observe and compare the efficacy and safety of implantation of tissue expanders adjacent to or under keloid tissues for large keloids on anterior chest. Methods Between Mar 2006 and June 2009, a total of 17 patients with large keloid lesions on anterior chest received treatment with 21 tissue expanders,among which 12 were placed under the normal skin adjacent to keloids, and 9 were inserted under the keloid lesions. The scar size varied from 4.5 cm × 3.0 cm to 15.7 cm × 5.5 cm. The capacity was 70 to 400 ml for expanders adjacent to the keloid tissue, 80 to 500 mi for those beneath the keloid tissues. After tissue expansion for 6 to 8 weeks, the expander was removed and keloid lesions were resected followed by the repair of defect with expanded flaps. Further more, the patients received intraoperative local intradermal injection of betamethasone and postoperative superficial electron beam irradiation with divided doses of 7 Gy in 3 consecutive days within 1 week after the surgery. Follow-up varied from 12 to 50 months. Results Twenty expanders, except 1expander pocket which was removed ahead of time due to infection, were implanted successfully during the whole course of treatment. The main complication was expander exposure in 4 patients, including 1 expander adjacent to the keloids and 3 under keloid lesions, which showed no significant influence on secondary operation. Fifteen patients reported relief of symptoms and achieved satisfactory outcomes, while 2 patients, including 1 treated with expanders adjacent to the keloids and 1 with expanders under the keloid tissue, showed great suture tension and experienced delayed stitch removal followed by the recurrence of keloids after the operation.Conclusions The implantation of tissue expanders under the adjacent normal skin or keloid lesions is an ideal treatment option for large keloids on anterior chest. Regional suture tension is a direct contributor to the recurrence of keloid formation after surgical excision.

A 70-year-old female patient presented with several cutaneous masses on the left neck and trunk for 40 years. Some masses were removed by surgical operation more than 10 years prior to the presentation, but recurred subsequently along with an increase in lesion number. Persistent dull pain emerged at the lesion sites 2 months prior to the presentation and the masses on the left neck ulcerated 10 days prior to the presentation. Histopathology showed tumor cell clumps in the dermis with benign eccrine spiradenoma components in the centre region and carcinomatous components in the periphery. The carcinomatous components included slightly atypical cells and hyaline degeneration. Immunohistochemically, carcinoembryonic antigen and epithelial membrane antigen were observed in the tumor tissues. The case was diagnosed as eccrine spiradenocarcinoma. The masses were surgically removed, but recurred 1 month later, increased in size and number and ulcerated 3 months later, and the patient died 6 months after the surgery.

Objective To investigate the clinical efficacy of Jin’s Three Needles plus twelve Jing-Well points in treating post-stroke shoulder-hand syndrome. Methods Sixty patients meeting the inclusion criteria of post-stroke shoulder-hand syndrome were randomly allocated to treatment and control groups, 30 cases each. The treatment group received acupuncture with Jin’s Three Needles plus twelve Jing-Well points and the control group, conventional acupuncture. The Clinical Neurological Disfunction Scale (CNDS) score, the Fugl-Meyer Assessment (FMA) score, the Visual Analogue Scale (VAS) score and the Functiional Comprehensive Assessment (FCA) score were observed in the two groups before and after two weeks of treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the CNDS, FMA, VAS and FCA scores in the two groups (P<0.05). The total efficacy rate and the cure and marked efficacy rate were 96.7%and 55.7%in the combination group, respectively, in the treatment group and 83.3%and 26.7%, respectively, in the control group;there were statistically significant differences between the two groups (P<0.05). Conclusion Acupuncture with Jin’s Three Needles plus twelve Jing-Well points is an effective way to treat post-stroke shoulder-hand syndrome.

Objective To establish the model of distraction osteogenesis for rabbit femur bone defect, and to observe the effect of icariin on regenerate ossification after distraction osteogenesis, thus to find a method for promoting regenerate ossification after distraction osteogenesis. Methods After the rabbit model of bone defect had been established successfully, the rabbits were equipped with distraction device. And then the 24 modeled rab bits were randomly divided into 2 groups. The experimental group was injected with icariin extract of Herba Epimedii into the interspace of bone distraction, and the control group was given local injection of recombinant human bone morphogenetic protein-2 (rhBMP-2, 100μg/kg) . On week 0, 1, 4 and 6 after the resting period, X-ray photography was carried out in both groups. On week 6 after distraction osteogenesis, the bone specimens of distraction osteogenesis region in both groups were observed by micro-computerized tomography ( CT) for the comparison of bone mass, and bone mineral content and mineral density of the newly-formed bone. Results The results of the features of imageology, and the statistical data of the bone mineral content and density showed that osteogenesis speed and osteogenic quality of the experimental group were superior to those of the control group. Conclusion The rabbit model of distraction osteogenesis for femur bone defect has been established preliminarily, and icariin can promote the speed and quality of regenerate ossification after distraction osteogenesis.

Objective To analyze clinicopathologic features of sebaceoma. Methods Clinical, pathologic and immunohistochemical findings from 31 cases of sebaceoma were retrospectively analyzed. The clinicopathologic features of sebaceoma were investigated. Results There were 9 males and 22 females. The patients′ age was 53.90 ± 15.40 years, and the clinical course was 9.41 ± 13.75 years. Sebaceoma predominantly affected the face. The common lesion of sebaceoma was red, yellowish?red, skin?colored or slight brown papules, with no subjective symptoms in most cases. Histopathologically, neoplasms had symmetric structures, and were located in the dermis. Epidermal involvements were found in 9 cases. The neoplasm cells were mainly composed of basaloid cells, a few mature sebocytes and some transition cells. The proportion of mature sebocyts was less than 1%in 26 cases, less than 20%in 2 cases, and 20%-40%in 3 cases. Mitoses were occasionally found in 5 cases. One patient was complicated by eccrine poroma. Varying amounts of ducts were found in all the patients. Immunohistochemical staining showed that epithelial membrane antigen was expressed on ducts and mature sebocytes in all the patients, while epithelial antigen was undetected in any of the patients. Carcinoembryonic antigen, androgen receptor and D2?40 were found in 20, 24 and 28 patients with sebaceoma, respectively. Conclusions The diagnosis of sebaceoma mainly depends on histopathological examination. Combined immunohistochemical detection of epithelial membrane antigen, androgen receptor and D2?40 is beneficial to its differential diagnosis.
