Objective To observe the impact of Aspergillus fumigatus conidia on the early apoptosis of alveolar epithelial cells.Methods A549 cells was first stimulated with tumor necrosis factor-α(TNF-α)or staurosporine (STS)to induce cell apoptosis,and then co-cultured with Aspergillus fumigatus conidia of three different concentrations (5 × 10 5 ,5 × 10 6 ,5 × 10 7 )simultaneously.The changes of the apoptosis rate of A549 cells were detected by flow cytometry.Results The early apoptosis of A549 cells was increased markedly after stimulated with TNF-α ([14.94 ± 0.82 ]% vs [3.26 ± 0.74]%,χ2 =9.18,P <0.05)and STS ([18.10±1 .00]% vs [3.26±0.74]%,χ2 =12.32,P <0.05). When Aspergillus fumigatus conidia of different concentrations were added,the apoptosis rate was decreased (χ2 =31 .23,P <0.05 ).The early apoptosis of A549 cells was negatively correlated with the concentration of Aspergillus fumigatus conidia (rTNF = - 0.92,r STS = - 0.94,both P < 0.05 ). Conclusion Aspergillus fumigatus conidia inhibits the early apoptosis of A549 cells induced by TNF-αor STS and the inhibit effect increases with the concentration of Aspergillus fumigatus conidia.

The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) is regarded as a regulator of TGFβ signaling pathway. This process depends on Smad7, the inhibitory factor of the TGFβ signal, and type I TGFβ receptor (TβR-I), one of the receptors of TGFβ. The expression level of USP15 seems to play vital roles in the pathogenesis of many neoplasms, but so far there has been no report about USP15 in psoriasis. In this study, immunohistochemical staining of USP15, TβR-I and Smad7 was performed in 30 paraffin-embedded psoriasis specimens and 10 normal specimens to investigate the expression of USP15, TβR-I and Smad7 in psoriasis and to explore the relevance among them. And USP15 small interfering RNA (USP15 siRNA) was used to transfect Hacat cells to detect the mRNA expression of TβR-I and Smad7. Of 30 cases of psoriasis in active stage, 28, 24 and 26 cases were positive for USP15, TβR-I and Smad7 staining, respectively. The positive rates of USP15 and Smad7 were significantly higher in psoriasis specimens than in normal skin specimens (44.1%±26.0% vs. 6.1%±6.6%, 47.2%±27.1% vs. 6.6%±7.1%), and positive rate of TβR-I (20.3%±22.2%) in psoriasis was lower than that in normal skin specimens (46.7%±18.2%). There was a significant positive correlation between USP15 and Smad7 expression, and significant negative correlations between USP15 and TβR-expression, an I d between TβR- and Smad7 expression I in psoriasis. After transfection of USP15 siRNA in Hacat cells, the expression of TβR-mRNA was up I -regulated and that of Smad7 was down-regulated. It is concluded that USP15 may play a role in the pathogenesis of psoriasis through regulating the TβR-I/Smad7 pathway and there may be other cell signaling pathways interacting with USP15 to take part in the development of psoriasis.

Abstract: Schistosomiasis is a serious major parasitic disease that threatens human life and health. A better understanding
of the mechanism of host-schistosome interactions is the key to designing new prevention and control strategies. MicroRNAs
(miRNAs) are endogenous small non-coding RNA molecules, which lead to the degradation of the target messenger RNA
(mRNA) or inhibition of its translation in a sequence-specific manner. Both schistosome and its host produce miRNAs, which
can be secreted by extracellular vesicles (EVs). There is accumulating evidence that miRNAs from schistosome can be taken
up by host cells, and finely manipulate the phenotype of host cells for their survival or pathogenesis in a cross-species manner,
even inhibiting the growth and metastases of hepatoma cells. It is still unknown whether host free miRNAs can be taken up by
schistosome, but this phenomenon is highly probable. miRNA-mediated cross-species regulation has emerged as a novel
mechanism for host-schistosome interactions, and this review summarizes the advances in this regard.

BACKGROUND:At present, the main research fields about coronary stents are the whole degradation biological materials with high biocompatibility and drug control ed release systems.
OBJECTIVE: To evaluate the safety after the two novel biodegradable stents implanted in coronary arteries in porcine models.
METHODS:The normal ful y biodegradable stents were made up of the poly-L-lactide and the antiproliferative drugs paclitaxel, and the novel biodegradable stents were added in amorphic calcium phosphate at the basis of normal biodegradable stents. (1) Five normal ful y biodegradable stents were randomly implanted into the coronary arteries of five porcines, and five novel biodegradable stents were randomly implanted into the coronary arteries of the remaining five porcines by coronary angiography. The blood biochemistry and C-reactive protein levels were measured pre-operation and at 28 days after operation. Coronary angiography was utilized to observe the lumen unobstructed at 28 days after surgery. (2) Under a microscope, seven normal ful y biodegradable stents and seven novel biodegradable stents were implanted into right external iliac arteries of 14 rabbits. Blood urea nitrogen and creatinine levels were measured before surgery and at 28 days after operation.
RESULTS AND CONCLUSION:At 28 days after operation, there were no significant changes in porcine glutamic-pyruvic transaminase, aspartate aminotransferase, triacylglycerol, total cholesterol, low density lipoprotein and C-reactive protein levels compared with that before operation, but urea nitrogen and creatinine levels were significantly higher than that before operation (P<0.05). The result of coronary angiography showed that no in-stent thrombosis or stenosis was detected in either group. There was no significant difference in urea nitrogen and creatinine levels in both groups. These results suggested that it is safe and compatible after the two novel biodegradable stents implanted in coronary arteries of porcine models, and the stents had good histocompatibility.
