A patient diagnosed with myoepithelial carcinoma was recently treated in our department. The neoplasm was huge, located in the left maxillofacial region, blocking both eyes, impeding feeding. About one month before admission, the tumor began to bleed frequently, about 100 ml each time, causing headache, dizziness, fatigue, and cold sweats. CT showed the maximum diameter of the tumor was about 23 cm, with uneven density, and maxillofacial bone destruction. MRI revealed internal bleeding and necrosis inside the tumor. After admission, blood routine test showed erythrocyte count 3.64 x 10(12)/L(↓), hemoglobin 106 g/L(↓), hematocrit 0.320 (↓), serum iron 6.2 μmol/L(↓). After surgery, the patient recovered smoothly.

Objective To investigate the influence of murine cytomegalovirus ( MCMV) infection on the expression of downstream differentiation related target genes of Wnt signaling pathway in neural stem cells (NSCs) in vitro and explore the molecular mechanism of fetal encephalodysplasia caused by CMV infection. Methods NSCs were separated from fetal BALB/c mouse and cultured in vitro. The NSCs infected by MCMV at a MOI (multiplicity of infection) of 5, 1 and 0.1, respectively, were cultured in differentiation medium. The dynamic expression of the downstream differentiation related target genes ( c-myc, cyclinD1, ngn-1 and ngn-2) of Wnt signal pathway in NSCs were measured by Western blot. Real-time RT-PCR was employed to measure the expression levels of the key differentiation genes ngn-1 in Wnt signal pathway of NSCs post infection. Results The protein levels of c-myc in the infected groups were significantly lower than that in the normal control at 0.5-5 d (P<0.05) ; At 0. 5 d and 1 d post-infection (p. i. ) , the protein levels of cyclinDl in the infected groups were lower than that in the normal control (P<0.05). At 2 d and 3 d p. i. , the cyclinD1 expression in the infected groups was higher than that in the control group (P < 0. 05). However, at 4 d and 5 d p. i. , the cyclinD1 levels in the group of the MOI of 5 were lower than in other three groups (F<0.05). The expression of ngn-1 protein in the infected groups was reduced importantly compared with normal control at 1 -5 d p. i. ( P < 0.05 ). The expression of ngn-1 mRNA in the infected groups was lower than that in the control group at all time points (P < 0. 05 ). The expression of ngn-2 protein decreased at first and then increased, which was opposite to the normal control. The peak of ngn-2 expression in groups of the MOT of 0.1 and 1 occurred later and were significantly lower than that in the normal control (P <0. 05). No distinct peak was seen in the group of the MOI of 5. At 1 d p. i. , the expression of ngn-2 of all infected groups was significantly lower than that in the normal control ( P < 0. 05 ). At 2 d p. i. , the expression of in the group of the MOI of 5 was still lower (P < 0.05). While at 3 d, 4 d and 5 d p. i. , the protein levels in all infected groups were higher than that in the normal control (P < 0. 05). The protein expression of these genes increased following the increase of MOI. Conclusion MCMV inhibited the protein expression of c-myc and ngn-1 in differentiated NSCs, repressed the mRNA expression of ngn-1 and caused the perturbed expression of cyclinDl and ngn-2 in a MOI-dependent manner. These data suggest that inhibition of or interference with the protein expression of downstream differentiation related target genes of Wnt signaling pathway in NSCs by MCMV may be one of the important mechanisms, by which proliferation and differentiation of NSCs are inhibited and thus fetal brain is impaired after MCMV infection.

An 81-year-old male presented with an 8-year history of recurrent ulcer on the left dorsal foot which gradually spread to involve both lower limbs. Physical examination revealed no abnormality of any organ systems and no palpable superficial lymph nodes. Skin examination showed erythematous swelling of the left dorsal foot with an ulcer sized 7 cm × 10 cm on the surface. Tendon was visible at the base of the ulcer, and the ulcer margin was elevated giving a dyke-like appearance. The perilesional skin was purple-brown. There were several millet-like papuloid lesions circularly arranged at the inner side of the right foot as well as dark erythematous or brown nodules and pigmented patches with tenderness on both lower limbs. Histopathology of the ulcer of the left dorsal foot and papuloid lesions on the right foot revealed a visible epidermotropic infiltrate in the epidermis as well as an infiltration throughout the entire dermis with medium-sized atypical lymphoid cells with obvious mitoses. Immunohistochemical examination showed the coexpression of both T cell markers (including CD3, CD45RO, CD43) and B cell marker (CD20), with scatted positive staining for PAX-5and negative staining for CD79α or CD1 9. PCR confirmed the rearrangement of T cell receptor (TCR)-γgene. A diagnosis of peripheral T cell lymphoma unspecified was made in view of the rearrangement of TCR-γgene and above findings. The patient was treated with the following modified CHOP regimen: intravenous cyclophosphamide 0.8 g, leurocristine 2 mg and epirubicin hydrochloride 60 mg, as well as oral prednisone 15 mg twice daily for 5 days every 3 weeks (one treatment session). After 3 treatment sessions, the lesions improved markedly.
