Objective To report 6 cases of hydroa vacciniforme-like cutaneous lymphoma,and to inves- tigate the relationship between this disorder and Epstein-Barr virus(EBV)infection.Methods Pathological and immunohistochemical examinations were performed in the biopsy specimens obtained from all 6 patients. Skin lesions were subjected to EBV encoded RNA(EBER)detection by in situ hybridization.Serological assay and quantification of EBV DNA were performed.Results All the 6 patients had recurrent papules, papulovesicles,necrosis and variola-like scar with chronic intermittent fever;four of the patients also presented with edema of the face,hands and feet.Pathologically,there were multilocular vesicles in the epidermis,and large numbers of infiltrating lymphocytes through the dermis.The cells were atypical with mitotic figures. Immunohistochemical staining of the lesions of 4 patients showed large quantities of cells expressing CD56, scattered cells expressing CD3 and CD45RO,and cells expressing grazyme B and T cell intracellular antigen-1 (TIA-1);a diagnosis of hydroa vacciniforme-like cutaneous NK/T lymphoma was made in these 4 cases. In the lesions of another 2 patients,the cells expressing CD3 and CD45RO,but not CD56,were observed; the diagnosis of hydroa vacciniforme-like cutaneous T-cell lymphoma was made in them.EBER was detected in the tumor cells of all the 6 patients.The IgG titers of anti-Epstein-Barr viral capsid antigen increased in all patients(1:5120 in 2 cases,1:2560 in 2 cases,1:1280 in 2 cases).The copies of EBV DNA were increased in the peripheral blood of both the two detected cases.A chronic active EBV infection was confirmed in all patients.Conclusions Hydroa vacciniforme-like cutaneous lymphoma is clinically characterized by edema of face,hands and feet,vesicular eruptions and variola like scars;histologically,it is characterized by infiltrates of atypical cells consistent with lymphoma,and necrosis in the center of vessels.NK/T is the primary immunophenotype of this disease.There is a close association between chronic active EBV infection and hydroa vacciniforme-like cutaneous lymphoma.

OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.
METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.
RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).
CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

Pericellular matrix (PCM) is a narrow tissue region surrounding chondrocytes, which "chondron" with its enclosed cells. A number of studies suggested that PCM is rich in proteoglycans, collagen and fibronectin, and plays an important role in regulating microenvironment of chondrocytes. Direct measures of PCM properties through micropipette aspiration technique showed that PCM was different from mechanical property of chondrocytes and nature extracellular matrix. However, the function of PCM is not clear, and need further study.

OBJECTIVETo investigate the effect of augmentative locking compression plate combined with bone graft in treating aseptic femoral shaft nonunion after intramedullary nailing.
METHODSTwenty-one cases with aseptic femoral shaft nonunion after intramedullary nailing from January 2007 to January 2013 were treated,including 18 males and 3 females with a mean age of 37.7 years (ranged from 23 to 64 years). The mean period of nonunion after surgery was 23.9 months (ranged from 9 to 62 months). According to Weber-Cech classification,10 of those 21 cases were hypertrophic nonunion,7 were atrophic, and 4 had oligotrophic fracture nonunion. All patients retained the original intramedullary nail, and applied with augmentation plating of 6 to 8 holes locking compression plate, unicortical fixation with 2 to 3 locking screws in the proximal or distal end, with simultaneous autologous iliac bone grafting. After treatment,all patients were allowed to partial weight-bearing until full weight-bearing according to the radiological results. All patients were followed up and were evaluated with clinical and imaging results.
RESULTSAll patients were followed up from 8 to 24 months, averaged (13.5±3.5) months,which showed clinical union at 4 to 8 months, averaged (6.0±1.0) months and radiological solid union at 7 to 12 months, averaged (9.1±1.5) months. No such complications as infection,hardware loosening or breaking were found.
CONCLUSIONAugmentative locking compression plate(LCP) combined with bone graft for aseptic femoral shaft nonunion after intramedullary nail has a satisfied clinical efficacy. It's an useful and simple method.

OBJECTIVE Hypericin, a powerful naturally photosensitizer in photodynamic therapy (PDT), is suitable for treating skin diseases involving excess capillary proliferation. In the present study, we aimed to evaluate the skin penetrability of a topically applied hypericin, expecting reducing the risk of prolonged skin photosensitivity, which often occurs after systemic administration. METHODS The Franz diffusion cell assay was performed to evaluate different penetration enhancers. In vivo studies, fluorescence microscopy was performed to examine the distribution of hypericin in the skin, macroscopic and microscopic analyses were also carried out to detect pathological changes in the skin after topical hypericin-PDT treatment. Immunohistochemistry was used to determine the expression of PECAM-1 in the treated skin. RESULTS 5% menthol facilitated hypericin penetrate the skin of nude mice most. The results of in vivo assays revealed that hypericin penetrated nude mice skin, spread to the dermis, and resulted in obvious photosensitivity reaction on the dermal capillaries. Moreover, skin injured by the photosensitive reaction induced by hypericin was replaced by normal skin 7 d after hypericin-PDT treat?ment. CONCLUSION Topical hypericin could penetrate nude mouse skin well and be great potential in PDT treatment of skin diseases.
