Objective To evaluate the diagnostic ability of dermoscopy in tiny pigmented basal cell carcinoma (BCC).Methods Fifty-eight patients with lesions measuring less than 5 mm in diameter and suspected for tiny pigmented basal cell carcinoma were enrolled in this study.The patients included 19 males and 39 females aging from 16 to 82 years.The disease course varied from 3 months to 25 years.The suspected lesions were examined by dermoscopy,then,two dermatologists independently made a diagnosis according to the findings on dermoscopy.Tissue specimens were also obtained from the suspected lesions for pathological diagnosis.The sensitivity,specificity and consistency with histopathology were calculated for dermoscopy in the diagnosis of tiny pigmented basal cell carcinoma.Results Of the 58 patients,36 were diagnosed with basal cell carcinoma according to pathological findings.Based on the dermoscopic features,41 cases were diagnosed as pigmented basal cell carcinoma by the dermatologist A,and 40 by the dermatologist B.The sensitivity,specificity,Youden index and Kappa value of dermoscopy were 97.22％,72.73％,69.95％ and 0.732 (P ＞ 0.05) respectively in the diagnosis of tiny pigmented basal cell carcinoma by the dermatologist A,97.22％,77.27％,74.49％ and 0.772 (P ＞ 0.05) respectively by the dermatologist B.Conclusion There is a high consistency between dermoscopy and histopathology in the diagnosis of tiny pigmented basal cell carcinoma.

Objective To study the effect of acupuncture cooperated with music therapy on cerebral palsy.Methods Sixty children with cerebral palsy were randomly divided into two groups with 30 in each: acupuncture group and acupuncture plus music group.The acupuncture group was treated with acupuncture only while the acupuncture plus music group treated with acupuncture at 5 groups of acupoints and music movement,once every other day,36 treatments as one course,totally 3 courses.The effect and movement improvement of both groups were observed for comparison.Results The comprehensive functions of all children were improved,but the total effective rate of acupuncture plus music group was obviously higher than that in acupuncture Group(P

Objective To retrospectively analyze the therapeutic effect of wide surgical excision combined with low-dose adjuvant interferon-alpha 2b on cutaneous malignant melanoma.Methods A total of 32 patients with cutaneous malignant melanoma received wide surgical excision after preoperative examination and staging.The excisions were performed with a margin measuring 1-2 cm from the visible lesions or biopsy scars.Surgical modalities included direct suture after excision(4 patients),dactylolysis or toe amputation(6 patients),free skin grafting(15 patients),random skin flap transfer(3 patients)and pedicle skin flap transfer(4 patients).Lymph nodes were selectively dissected in 9 patients with regional transfer of lymph nodes,and inguinal lymph nodes were cleared away in 2 patients.One week after the operation,patients received adjuvant therapy with subcutaneous injection of interferon-alpha 2b(3 million IU,thrice per week)for one to three years.Results Preoperative tumor staging revealed 21 cases of cutaneous malignant melanoma at stage Ⅱ,and 11 cases at stage Ⅲ.The excisions healed by the first stage in all the patients.Up to June 2011,2 patients had been lost to follow up,5 patients with stage Ⅲ melanoma had died.Survival was observed in all of the 4 patients receiving 1-year follow up,12 of 13 patients receiving 1-3 year follow up,5 of 7 patients receiving 3-5 year follow up,and 4 of 6 receiving 5-year follow up.Of the 25 surviving patients,regional lymph node metastasis was observed in 8 patients,which developed within 2 years after the operation in 2 patients.The adjuvant therapy with interferon-alpha 2b lasted 3 years in 8 patients,and more than 1 year in 11 patients.Side effects were mild.Conclusion Wide surgical excision plus low-dose interferon-alpha 2b is effective for the treatment of stage Ⅱ and Ⅲ cutaneous malignant melanoma with lower local recurrence and higher survival rate.

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 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 investigate the efficacy of dermabrasion combined with aminolevulinic acid-based photodynamic therapy (ALA-PDT) for the treatment of nasal nodular basal cell carcinoma (nBCC).Methods Twentyfive patients who were pathologically diagnosed as nasal nBCC with lesion area ＞ 1 cm2 but no bone or cartilage involvement,were included in this study and treated with dermabrasion combined with ALA-PDT.At first,the part of tumor protruding outside the skin was removed by artherectomy,then dermabrasion was carried out.The wound surface was topically treated with 20％ aminolevulinic acid solution for 3-4 hours away from light immediately after surgery,then irradiated with LED light at a mean dose of 100 J/cm2 for 20 minutes.ALA-PDT was performed once a week for 3 consecutive weeks.The degree of and time required for wound healing were assessed,and tumor recurrence,cicatrization and appearance outcomes were observed during 1 year after surgery.Efficacy was assessed comprehensively.Results No postoperative wound infection occurred in these patients,and the average time for wound healing was (11.2 ± 1.3) days.During 1 year after the treatment,no recurrence was found,while cicatricial contracture developed in 1 case,mild proliferative scar in 3 cases,and depressed scar in 4 cases.All the patients were satisfied with the treatment outcomes,except 1 patient who was basically satisfied.Conclusions Dermabrasion combined with ALA-PDT is easy to operate with rapid wound healing,low postoperative recurrence rate and high degree of patient satisfaction,and is worthy of clinical promotion.

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 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.
