Writer＇s imagination does not only provide inspiration for literary creation, but also contribute literature works with more dazzling brilliance. As a representative of the British Romantic Poetry--William Blake, whose poems are full of imagination, always concedes his emotion and thoughts in a variety of imageries, exposing the reality of his times within his poetry writing. However. William Blake＇s imagination is no castles in the air, but based on the religious mythology, historical background, and the poet＇s life experience and dream pursuit. Only with in-depth understanding of the imagination in William Blake＇s poems can those hidden emotions and thoughts be grasped and appreciated.

To investigate the biological character of human adipose-derived adult stem cells (hADAS cells) when cultured in vitro and the relationship between hADAS cell’s replication activity and the donor’s age factor, and to assess the stem cells as a new source for tissue engineering. hADAS cells are isolated from human adipose tissue of different age groups (from adolescents to olds: 61 years old groups). The protein markers (CD29, CD34, CD44, CD45, CD49d, HLA-DR, CD106) of hADAS cells were detected by flow cytometry (FCM) to identify the stem cell, and the cell cycle was examined for P20 hADAS cells to evaluate the safety of the subculture in vitro. The generative activity of hADAS cells in different age groups was also examined by MTT method. The formula “ log2T D = t logN t ? logN 0” was used to get the time doubling (TD) of the cells. The results showed that the cells kept heredity stabilization by chromosome analysis for at least 20 passages. The TD of these cells increased progressively by ageing, and the TD of the 61 years old group (statistical analysis of variance (ANOVA), P=0.002, P<0.05). These find- ings suggested that a higher level of hADAS cells replication activity was found in the younger dona- tors, and they represent novel and valuable seed cells for studies of tissue engineering.

The efficacy and applied value of endoscopic hematoma evacuation vs. external ventricular drainage (EVD) in the treatment of severe ventficular hemorrhage (IVH) were explored and *** Jan.2015 to Dec.2016,the clinical data of 42 cases of IVH were retrospectively analyzed,including 18 patients undergoing endoscopic hematoma evacuation (group A),and 24patients receiving EVD (group B).The hematoma clearance rate was calculated by 3D Slicer software,and complications and outcomes were compared between the two *** were no significant differences in age,sex and Graeb score between groups A and B (P>0.05).The hematoma clearance rate was 70.81%±27.64% in group A and 48.72%±36.58% in group B with a statistically significant difference (P<0.05).The operative time in groups A and B was 72.45±25.26 min and 28.54±15.27min,respectively (P<0.05).The Glasgow Coma Scale (GCS) score increased from 9.28±2.72 at baseline to 11.83±2.91 at 1 week postoperatively in group A,and from 8.25±2.62 at baseline to 10.79±4.12 at 1 week postoperatively in group B (P<0.05).The length of hospital stay was 12.67±5.97 days in group A and 17.33±8.91 days in group B with a statistically significant difference (P<0.05).The GOS scores at 6 months after surgery were 3.83±1.12 in group A,and 2.75±1.23 in group B (P<0.05). These results suggested that endoscopic hematoma evacuation has an advantage of a higher hematoma clearance rate,fewer complications and better outcomes in the treatment of severe IVH,indicating it is a safe,effective and promising approach for severe IVH.

The increasing intensity and frequency of sand-dust storms in China has led to greater prominence of associated environmentaland health issues. Many studies have focused on the health effects of air particulate contaminants, but fewformal investigations have studied the effects of sand-dust storms on human and animal health. The aim of this study wasto investigate the effects of dust storms on rat lung by using high resolution computed tomography （HRCT） and blood gasanalysis through a wind tunnel simulating. We found that the rat lung damage effects can be detected by the HRCT imagingafter exposure to sand-dust storm environments, but had no obvious result through blood gas analysis. Exposure durationspositively correlated with the damage degree to lung tissue. These will provide some evidence for clinical diagnosis ofnon-occupational pneumoconiosis.

AIM To compare therapeutic responses of a vascular-disrupting-agent, combretastatin-A4-phosphate(CA4 P), among hepatocellular carcinomas(HCCs) and implanted rhabdomyosarcoma(R1) in the same rats by magneticresonance-imaging(MRI), microangiography and *** Thirty-six HCCs were created by diethylnitrosamine gavage in 14 rats that were also intrahepatically implanted with one R1 per rat as monitored by T2-/T1-weighted images(T2wI/T1wI) on a 3.0 T clinical MRIscanner. Vascular response and tumoral necrosis were detected by dynamic contrast-enhanced(DCE-) and CE-MRI before, 1 h after and 12 h after CA4P iv at 10 mg/kg(treatment group n = 7) or phosphate-buffered saline at 1.0 mL/kg(control group n = 7). Tumor blood supply was calculated by a semiquantitative DCE parameter of area under the time signal intensity curve(AUC30). In vivo MRI findings were verified by postmortem *** On CE-T1wIs, unlike the negative response in all tumors of control animals, in treatment group CA4P caused rapid extensive vascular shutdown in all R1-tumors, but mildly or spottily in HCCs at 1 h. Consequently, tumor necrosis occurred massively in R1-tumors but patchily in HCCs at 12 h. AUC30 revealed vascular closure(66%) in R1-tumors at 1 h(P < 0.05), followed by further perfusion decrease at 12 h(P < 0.01), while less significant vascular clogging occurred in HCCs. Histomorphologically, CA4P induced more extensive necrosis in R1-tumors(92.6%) than in HCCs(50.2%)(P < 0.01); tumor vascularity heterogeneously scored +^+++ in HCCs but homogeneously scored ++ in *** This study suggests superior performance of CA4P in metastatic over primary liver cancers, which could guide future clinical applications of vascular-disruptingagents.
