A case of benign follicular neoplasm-trichogerminoma-is reported.A 48-year-old man presented with a 10-year history of asymptomatic subcutaneous nodule in the chest.Histological examination revealed a well-circumscribed lesion composed of variously sized lobuli and cysts in the deep dermis and separated from the surrounding tissue by a fibrous capsule.Most lobuli consisted of concentrically arranged clear cells in the central area and basophilic cells in a palisade arrangement in the peripheral area.The tumor cells displayed a multi-directional differentiation toward hair bulb,inner root sheath,outer root sheath and infundibulum of hair follicles.Immunohistochemically,the tumor cells expressed AE1/AE3,CK5/6 and CK17,but were negative for CK20 or CK7.There was a sharp contrast in immunohistochemical findings between the central clear cells and peripheral basophilic cells.Based on the histological and immunohistochemical features,a diagnosis of trichogerminoma was made.

A 36-year-old woman presented with a 3-year history of pruritic erythema and scaling on the trunk and extremities.Dermatological examination revealed ill-defined light pink macules with white lamellar scales on the chest,abdomen and buttocks.Histologically,there was a focal mononuclear cell infiltrate in the superficial dermis,with the epidermotropism of some cells and mild atypia of epidermotropic cells,as well as an interstitial mononuclear cell infiltrate and mild deposition of mucin between the collagen fibers in the middle dermis.CD3 and CD4 were expressed by scattered mononuclear cells infiltrating the upper and middle dermis.Based on these data,the patient was diagnosed with interstitial granuloma fungoides.

BACKGROUND:Previous studies have demonstrated that normal rat liver homogenate supernatant can induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels with partial hepatocyte functions. However, whether fibrotic liver homogenate supernatant can work or how the inducing effect is remains unclear. OBJECTIVE:To investigate the differentiation potential of human umbilical cord mesenchymal stem cels into hepatocytes under the normal liver and fibrotic liver microenvironment in vitro. METHODS:Liver fibrosis was induced in the SD rats by repeated intraperitoneal injections of 3% thioacetamide at a dose of 200 mg/kg body mass, twice a week for 4 weeks, and then fibrotic liver tissues and normal liver tissues were used to prepare liver homogenate supernatants. Passage 3 human umbilical cord mesenchymal stem cels were used and divided into standard control group (cels were cultured in DMEM/F12 with 10% fetal bovine serum), fibrotic liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 50 g/L fibrotic liver homogenate supernatants), normal liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 100 g/L normal liver homogenate supernatants). The morphological changes of the cels in each group were recorded under inverted microscope; the protein levels of CK18, AFP, CYP3A4, CYP2E1, CYP2D6 and TPH2 were evaluated using western blot assay. Furthermore, the concentration of albumin in the cels was measured. RESULTS AND CONCLUSION:After a 7-day inducement, the stem cels in liver homogenate supernatants groups lost their fusiform shape and changed into hepatocyte-like cels with the morphous of round shape. Compared with the standard control group, the hepatocyte-like cels in the two liver homogenate supernatants groups exhibited human hepatocyte biomarkers, CK18 and AFP. The standard control group cels could express a little amount of CYP2E1, while cels in the two liver homogenate supernatants groups could express CYP3A4, CYP2E1, CYP2D6, TPH2. Compared with the standard control group, the expression level of CYP2E1 in the two liver homogenate supernatants groups increased significantly (P < 0.01), and however, the relative levels of CYP3A4, CYP2E1, CYP2D6, TPH2 in the two liver homogenate supernatants groups showed no statistical significance (P > 0.05). At the same time, compared with the standard control group, the concentration of albumin in the two liver homogenate supernatants groups markedly increased (P < 0.01), but there was no difference between the two liver homogenate supernatants groups (P > 0.05). Experimental findings demonstrated that both of normal liver tissue and fibrotic liver tissue microenvironments could induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels. To achieve the same effect, compared with normal liver tissue, fibrotic liver tissue required lower concentrations, suggesting that fibrotic liver tissue microenvironment may be more conducive to differentiation of umbilical cord mesenchymal stem cels into hepatocytes.

BACKGROUND:Preliminary experiments have demonstrated that rat liver homogenate supernatants can induce the morphological changes of human umbilical cord mesenchymal stem cells. However, little is known about whether the induced cells have some phenotypic and functional features of hepatocytes.
OBJECTIVE:To investigate whether human umbilical cord mesenchymal stem cells have some phenotypic and functional characteristic of hepatocytes after being induced by liver homogenate supernatants.
METHODS:Passage 3 human umbilical cord mesenchymal stem cells were used and divided into control group (cells were cultured in basic culture medium) and liver homogenate supernatant group (cells were cultured in liver homogenate supernatants for 3, 5, 7 days). Meanwhile, positive control group (QSG-7701 human liver celllines) and negative control group (simple liver homogenate supernatants) were set up. The protein and mRNA level of hepatocyte markers, alpha-fetoprotein, cytokeratin 18 and tryptophan 2,3-dioxygenase enzyme, were detected at different time points.
RESULTS AND CONCLUSION:After inducement, the stem cells of fusiform shape began to lose their sharp edges and progressively shrunk, and then they changed into hepatocyte-like cells with the morphous of triangle, polygon and anomalism shape. Compared with the control group, the protein and mRNA level of alpha-fetoprotein, cytokeratin 18 and tryptophan 2,3-dioxygenase enzyme significantly increased time dependently after inducement with liver homogenate supernatants (P<0.01). This study demonstrated that human umbilical cord mesenchymal stem cells are able to differentiate into hepatocyte-like cells in vitro that possess some functions of liver cells.

Objectives To investigate the recurrence risk factors and the protective factors of aortic dissection (AD) DeBakey type Ⅲ. Methods 43 patients with AD DeBakey type Ⅲ who were in Guangdong General Hospital from May 2014 to September 2014, were enrolled as the case group, while 27 volunteers exclude AD as the control group. Blood chemistries and other information obtained immediately after admissions , χ2 test or T test was used for univariate analysis of independent samples. Multivariate Logistic regression analysis was used to screen patients with recurrence risk factors or protective factors. Results The prevalence of hypertension (93.02%vs. 18.52%, P = 0.000) and proportion of smokers (34.88% vs. 11.11%, P = 0.027) were significantly higher in case group than control group. Logistic regression analysis showed that hypertension (OR=5.148, 95%CI= [2.209~13.058], P=0.001) and albumin level (OR=0.709, 95%CI = [0.541~0.929], P=0.013) were significantly associated with recurrence of aortic dissection DeBakey type Ⅲ. Conclusion Hypertension is an independent risk factor for recurrence of aortic dissection DeBakey type Ⅲ, and albumin level is a protective factor.

Objective To investigate the effect of BRAFV600E mutation on the invasion capacity of a human melanoma cell line, A375. Methods Plasmids containing short hairpin RNAs (shRNA) specific for BRAF gene were prepared in previous study, and used to transfect A375 cells. Those cells transfected with negative plasmid and untransfected cells served as the controls. Transwell chambers were used to examine the invasion ability of melanoma cells in vitro. RT-PCR and Western blotting were performed to detect the mRNA and protein expressions of matrix metalloproteinase 2 (MMP-2) and vascular endothelial growth factor (VEGF), respectively, before and after the transfection. The activity of MMP-2 was also studied with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Results Compared with the negative control, the specific shRNA decreased the mRNA and protein expressions of MMP-2 by 35% and 85%, respectively, and those of VEGF by 45% and 14%, respectively. Additionally, the number of cells invading through Matrigel chambers reduced by 69% in those cells transfected with the positive plasmid. Conclusions The mutant BRAFV600E has the potential to enhance the invasion capacity of melanoma cells, whereas specific shRNA could suppress the increase in metastasis capacity likely by inhibiting the production of VEGF and MMP.

Objective To construct the eukaryotic expression plasmids of short hairpin RNA (shRNA) specific for mouse Bcl-2-assoeiated athanogene 1 (BAG-1) and to observe their inhibitory effects on the expression of BAG-1 gene in mouse melanoma B16FI0 ceils. Methods Plasmids named pRNAT-U6.1/Neo-BAG-1, were designed and constructed to target the mouse BAG-1 mRNA coding region. LipofectaminTM 2000 was used to transfect plasmids into BI6F10 cells. Negative plasmid-transfected and tmtransfected B16F10 cells served as negative and blank controls respectively. Forty-eight hours following transfection, G418 was used to select the resistant cells. The mRNA and protein expression of BAG-1 gene was measured by reverse transcription-PCR and Western blot respectively about 1 month after the transfection. Results The eukaryotic expression plasmids, pRNAT-U6.1/Neo-BAG-1, were constructed, and verified by restriction enzyme digestion and DNA sequencing. The transfection rate in B16F10 cells was 20% -30%. Compared with the blank control, the mRNA and protein expression of BAG-1 in BI6FI0 cells was significantly inhibited by BAG-1 shRNA (both P<0.05), and the inhibition rates were (77±4)% and (62 ±2)%, respectively. Conclusions These results indicate that the eukaryotic expression vectors containing shRNA against BAG-1 gene, pRNAT-U6.1/Neo-BAG-1, are successfully constructed, and can significantly inhibit the expression of BAG-1 gene in mouse melanoma B16F10 cells.
