The study group received Taoist cognitive therapy for 3 months in addition to basic medical treatment.The control group was treated with medicine only.Both groups were followed for 6 months and evaluated with psychological scales,including Type A behavior scale,mental detachment scale.Clinical efficacy was also evaluated.Results:The score of type A had significant decreased from 25.8?7.6 to 20.8?5.8 after 3 months in the study group,the score of mental detachment significantly increased from 28.7?4.4 to 31.8?3.8(P

OBJECTIVETo investigate the influence of pleiotrophin (PTN) on the growth of rat hepatocytes.

METHODSPrimary rat hepatocytes were isolated from male Sprague-Dawley rats and divided into three groups: group A (negative control), cultivated in normal culture medium; group B (positive control), cultivated with culture medium supplemented with supernatant from the embryonic fibroblast 3T3 cell line; group C (experimental), cultivated with culture medium supplemented with human recombinant (hr) PTN (100 ng/ml). The hepatocytes' growth rate and level of secreted albumin (ALB) were evaluated by microscopy and biochemical assay, respectively. Significance of between-group differences were assessed by one-way ANOVA, and pairwise comparisons were performed by the least significant difference test.

RESULTSThe growth rates of hepatocytes in groups A, B and C were 2.800+/-0.084%, 4.300+/-0.132% and 3.800+/-0.053%, respectively. The growth rate of group B was significantly higher than the other two groups (F = 333.735, P less than 0.05). For all groups, the highest levels of secreted ALB were detected between the second and sixth day of culture, with g/L concentrations at day 2, 4 and 6 of: group A, 0.550+/-0.010, 0.900+/-0.030 and 0.300+/-0.040; group B, 0.900+/-0.030, 1.300+/-0.020 and 1.400+/-0.030; group C, 0.900+/-0.010, 1.160+/-0.010 and 0.700+/-0.050. The secreted ALB of group B was significantly higher than that of the other two groups (F = 651.355, 338.831 and 863.205, P less than 0.05 ).

CONCLUSIONPTN can benefit in vitro culturing of rat hepatocytes by stimulating growth and enhancing their ability to secrete albumin.

This paper presents a computer-aided diagnosis method for prostate cancer detection using Trans-rectal ultrasound(TRUS) images. Firstly, statistical texture analysis is implemented in every ROI in segmented prostate images. From each ROI, grey level difference vector features, edge-frequency features and texture features in frequency domain are constructed. Then, the number of features is reduced using ANOVA statistics to select the optimal feature subset. Finally, SVM is applied to the selected subset for detecting the cancer regions. Experimental results show that the proposed algorithm can recognize and detect the cancer images effectively so as to supply essential information for a diagnosis.

In this paper, we propose that, the need of the costly re-initialization procedure can be completely eliminated by using the variation formulation, thus increasing the speed of computing operations. The edge detecting function in the geodesic active contour model is improved by incorporating a prior knowledge. The accuracy of the segmentation algorithm can be enhanced by using the minimal variance. Experimental results show that the proposed algorithm can segment the prostate ultrasound images effectively and avoid the problem of contour leakage.

This study was to purposed to explore the methylation status changes of IEX-1 gene promoter CpG island and its relevance with occurrence of hematologic malignancies. The methylation status of IEX-1 gene promoter CpG island in 9 NB4, HL-60 U937, Raji, CA46, Jurkat, K562, CEM and Molt4 hematologic malignant cell lines was detected by using methylation-specific PCR, the methylation status of IEX-1 gene promoter CpG island in normal peripheral blood mononuclear cells treated by M. sssI enzyme and the methylation status of IEX-1 gene promoter CpG island in normal peripheral blood mononuclear cells untreated were used as positive and negative controls respectively. The results showed that the hypermethylation of IEX-1 gene promoter CpG islands was detected in NB4, Molt4 and Raji cell lines, as well as in normal peripheral blood mononuclear cells treated by M. sssl enzyme; the partial methylation status was found in CA46, CEM, U937, K562, HL-60 and Jurkat cell lines; the unmethylation status was observed in untreated normal peripheral blood mononuclear cells. It is concluded that the changes of methylation status of gene IEX-1 promoter CpG island correlates with hematologic malignancies to a certain extent.

OBJECTIVEThis study was designed to explore the optimal management option for cervical metastases in tongue squamous cell carcinoma (SCC) with clinically N0 neck in order to avoid excessive or inadequate treatment in clinical practice.

METHODSClinical data of 327 cases of tongue SCC with cN0 neck were retrospectively analyzed. Neck control rates affected by different pathoclinical parameters were compared. Prognosis analysis and death analysis were also performed.

RESULTSOverall 3-year survival was 69.7% (228/327), 3-year survival of neck recurrent group and non-recurrent group was 39.1% (25/64) and 77.2% (203/263), and 51.5% (51/99) of the death related to neck failure. Overall neck control rate was 80.4% (263/327); neck control rate of wait and watch group, level I neck dissection, level I + II neck dissection, supraomohyoid neck dissection, radical neck dissection, functional neck dissection, was 67.5% (27/40), 72.7% (24/33), 60.0% (15/25), 84.9% (45/55), 86.8% (131/151), 84.0% (21/25), respectively. Treatment modality and cervical lymph node involvement were independent factors for neck control.

CONCLUSIONSNeck control is a key for prognosis of tongue SCC with cN0 neck. Supraomohyoid neck dissection is the first choice in management of cervical metastases in tongue SCC with cN0 neck, during which the suspected involved lymph nodes should be sent for frozen section to determine whether comprehensive neck dissection required. Multimodal metastasis and/or capsular spread are the indications for postoperative irradiation.
