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.

Purpose To discuss the value of MRI in the diagnosis of placenta implantation abnormality, and to explore preliminarily the relationship between MRI signs and types of placenta implantation abnormality. Materials and Methods The clinical preoperative data and postnatal pathological findings of 54 women at high risk of placenta accreta were collected. All the patients undertook the conventional pelvic MRI examination. The scanning sequences mainly included: sagittal, coronal and axial T2-weighted imaging-turbo spin echo, balance fast field echo. The MRI images were observed and the areas which showed low signal in all the three directions on T2WI were measured. Then the correlation between the areas of low signal on T2WI in placental and the types of placenta implantation abnormality was analyzed. Results The incidence of placenta implantation abnormality was 64.8% in our research (35/54). The main MRI signs were low signal on T2WI (68.5%, 37/54) and heterogeneous signal in placenta (57.4%, 31/54); the main sign of placenta percreta was tenting bladder (75.0%, 6/8). The types of placenta implantation abnormality were positively correlated with the areas of low signal on T2WI (r=0.454, P<0.05). Conclusion Pregnant women at risk of placenta accreta should be evaluated with imaging examinations, particularly with MRI scanning, to improve disease detection rate. The typical indirect signs of placenta implantation abnormality are low signal on T2WI and heterogeneous signal in placenta. The larger size of low signal area on T2WI in placenta, the deeper implantation of placenta.

OBJECTIVETo compare the Golgi proteome of hepatocellular carcinoma (HCC) with that of the adjacent non-tumor tissues.
METHODSHepatocellular carcinoma and adjacent non-tumor tissues were obtained from HCC patients. The protein expression maps in Golgi were obtained by two-dimensional gel electrophoresis (2-DE), and the differentially expressed protein spots were analyzed by PD-Quest software. Peptide mass fingerprint (PMF) of differential protein spots was obtained with MALD-TOT-MS.
RESULTSAccording to 2-DE maps, the average numbers of protein spots were (1153+/-49) and (1086+/-37) in hepatocellular carcinoma and the adjacent non-tumor tissues. Compared to the adjacent non-tumor tissues, 27 proteins were upregulated, and 20 proteins were downregulated in HCC Golgi.
CONCLUSIONSThe Golgi proteome in HCC tissues is different from that in the adjacent non-tumor tissues, and the differential expression proteins are involved in energy metabolism, tumor metastasis, and cell cycle regulation.

OBJECTIVETo explore the correlationship between platelet count and efficacy of traditional Chinese medicine (TCM) or Western medicine (WM) in treating rheumatoid arthritis (RA) patients.
METHODSA total of 356 patients with confirmed diagnosis of active RA from 9 clinical centers were randomly assigned to the TCM group (184 cases) and the WM group (172 cases). The TCM group was treated with basic therapy (administration of glucosidorum tripterygll totorum and Yishen Juanbi Pill) and TCM syndrome differentiation dependent treatment, while the WM group was treated with non-steroidal anti-inflammatory drugs and slow-acting anti-rheumatic drugs. The therapeutic efficacy was assessed with ACR20, the joint damage degree of both hands was evaluated by X-ray.
RESULTSThe platelet count was positively correlated to the X- ray grading of joint damage, namely, patients with a more severe joint damage often presented a higher platelet count. After treatment, in patients with joint damage of X-ray grade II or III and effectively treated with TCM, also in patients with joint damage of grade III and effectively treated with WM, the platelet count was lower than that in those treated ineffectively.
CONCLUSIONPlatelet count is closely correlated to the efficacy of drug therapy, therefore, it may be taken as an important index for judging the curative effect of therapeutic approach in treating RA patients.

OBJECTIVETo explore the correlations between diagnostic information and therapeutic efficacy in rheumatoid arthritis (RA) with decision tree model analysis.
METHODSThree hundred and ninety seven patients came from 9 clinical centers were randomly divided into the Western medicine (WM) group (n=194) treated with non-steroidal anti-inflammatory drugs and slow-acting antirheumatic drug and the Chinese medicine (CM) group (n=203) with basic therapy and syndrome-differentiation dependant TCM treatment. TCM and WM diagnostic information were collected. The ACR 20 was used for efficacy evaluation and the information of patients before treatment was analyzed by SAS 8.2 statistical package. Through single-factor exploratory analysis, odds ratio of efficacy and variable was calculated taken P < 0.2 as the including criteria for data mining analysis with decision tree model. All data were classified into the training set (75%) and verifying set (25%) with efficacy as the variable for layering to make further verification of the data-mining analysis.
RESULTSTwenty variables were included in the CM group and 26 in the WM group in the data-mining model. In the former, 9 variables were positively correlated to the efficacy, including degree of arthralgia, tenderness and morning stiffness, number of swollen joint, and joint with tenderness, levels of IgM, rheumatoid factor (RF), C-reactive protein (CRP), and total assessment from doctor; and disease duration and degree of nocturnal polyuria were negatively correlated to that. While in the latter, 8 were positively correlated to the efficacy, including erythrocyte sedimentation rate (ESR), sour and weak waist and knees, white fur in tongue, joint ache and stiffness, swollen joint, and total assessment from doctor and patient, and red tongue with yellow fur and leucocyte count negatively correlated to it. Data mining with decision tree analysis revealed that different combinations of morning stiffness, slight red tongue, joint tenderness and nocturnal polyuria in the CM group, and those of white fur in tongue, CRP level, leucocyte count and morning stiffness in the WM group showed different efficacy, which were also verified in the randomly chosen verifying set.
CONCLUSIONTo analyze the correlations between diagnostic information and therapeutic efficacy with decision tree analysis is conformed to the theory of TCM in applying treatment according to syndrome differentiation individually, thus it would contribute to elevate the accuracy of therapy.

Heme oxygenase-1 (HO-1) is a cytoprotective enzyme that catalyzes the conversion of heme to CO, biliverdin, and iron, which together protect cells from oxidative and inflammatory damage and play an important role in maintaining cell homeostasis. In recent years, HO-1 has also been found to have antiviral biological effects, and the induced expression of HO-1 inhibits the replication of various viruses such as hepatitis C virus, hepatitis B virus, human immunodeficiency virus, dengue virus, ebolavirus, influenza A virus, Zika virus, severe acute respiratory syndrome coronavirus 2, human respiratory syncytial virus, hepatitis A virus and enterovirus 71. The inhibitory effect of HO-1 on these viruses involves three mechanisms, including direct inhibition of virus replication by HO-1 and its downstream products, enhancement of type I interferon responses in host cell, and attenuation of inflammatory damage caused by viral infection. This review focuses on the recent advances in the antiviral effect of HO-1 and its mechanism, which is expected to provide evidence for HO-1 as a potential target for antiviral therapy.
