1.TNF-related apoptosis inducing ligand and its biological functions
Chinese Journal of Pathophysiology 2000;0(10):-
TNF-related apoptosis-inducing ligand(TRAIL) is a type II transmembrane protein in TNF family. TRAIL influences a variety of immunological functions including cellular activation, proliferation and death, upon interation with a corresponding super family of receptors. This article is about the new views on the biological functions of TRAIL.
2.Non-coding RNAs in castration-resistant prostate cancer.
National Journal of Andrology 2015;21(11):1014-1019
Non-coding RNAs (ncRNAs) are a large class of RNA molecules that do not encode proteins, regulate gene expressions multifacetedly, and influence the metabolism, proliferation, differentiation and apoptosis of cells as well as the occurrence and progression of tumors. Some of the ncRNAs act as cancer genes, such as miR-19a, miR-125b, miR-616, miR-7, miR-221, MALAT-1, and PRNCR1, which are upregulated in castration-resistant prostate cancer (CRPC) tissues or cell lines, and promote the development and progression of CRPC, some act as tumor suppressor genes, including miR-185, miR-342, miR-15, miR-16, and miR-146, which are downregulated in CRPC tissues or cell lines and inhibit or delay the occurrence of CRPC, and still others, such as miR-7, miR-19a, miR-125b, miR-221, and MALAT-1, are differentially expressed in the serum or tissue and can be used as potential biomarkers for the early diagnosis and prognosis of CRPC. This article presents an overview on the roles of ncRNAs in the occurrence, progression, diagnosis, and prognosis of CRPC and advances in their studies.

Objective To display efficient folding hDAF on the surface of yeast. Methods The hDAF open reading frame was cloned by PCR from DAF- pBluescript M13-(Amp+)plasmid, then subcloned into the yeast surface displayed vector pYD1.The recombinant vector was transformed into yeast cells EBY100.Flow cytometric analysis was carried out to evaluate direct binding of anti-DAF mAbs onto the surface of yeast cells displaying DAF. Results Three mAbs against DAF different epitopes could bind onto DAF displayed on the surface of yeast.Conclusion Efficient folding DAF can be displayed on the surface of yeast potentially leading to the development of novel applications involving DAF yeast display.

Objective To observe the efficacy of psychological intervention on treatment compliance rate, clinical effect and quality of life in patients with advanced cancer pain.Methods Using a sealed envelope method, 80 patients with advanced cancer pain were randomly divided into two groups: the experimental group (EG) (40 cases) and the control group (CG) (40 cases).All patients were treated with standardized cancer pain treatment, and the patients of EG were treated with positive psychological intervention.The treatment compliance rate, clinical effect and quality of life after intervention by 14 days between two groups were compared.Results In EG and CG, the clinical efficiencies of cancer pain were 95.0 % (38/40) and 80.0 % (32/40), respectively (P < 0.05).The treatment compliance rates were 87.5 % (35/40) and 62.5 % (25/40), respectively (P < 0.01), and the improvement rates of quality of life were 80.0 % (32/40) and 57.5 % (23/40), respectively (P < 0.05).Conclusion Psychological intervention is effective to improve the treatment compliance, clinical effect and quality of life for the patients with advanced cancer pain.

Arnebia euchroma is the main source for medicinal herb Zicao. and its most important component shikonin compounds have high medicinal and industrial value. This research is aimed to build overexpression vectors and RNAi vectors for key secondary metabolism genes of A. euchroma, and bulid platform for constructions of related transgenic lines using GATEWAY technology. To build genetic material based genetic research platform is to provide a great convenience for digging and functional verification of the genes on secondary metabolic pathway, and also to fill the gaps in transgenic research of A. euchroma. This study is also important for the cultivation of shikonin high-yielding strains of A. euchroma.

Twenty-seven ERF transcription factor family genes were isolated from Arnebia euchroma, with an average size of 1,010 bp, each gene encoded a 212 amino acids on average. The gene structure and expression of physicochemical properties, subcellular localization, signal peptides, senior structural domains and conservative forecasting, and analysis of A. euchroma were studied comparing with ERF gene gi261363612 of Lithospermum erythrorhizon, and phylogenetic analysis of A. euchroma ERF family was carried out. The results showed the existence of three conserved domains in this family, the senior structure based on random coil and it clustered into CBF/DREB and ERF subfamilies.

Objective To evaluate the 64-slice CT angiography in characterizing the coronary venous anatomy and the arterio-venous relationship.Methods Sixty-four slice CT coronary veins angiography images of 300 patients(187 men and 113 women,)were analyzed.The visibility of the coronary veins and arterio-venous spatial relationship were assessed qualitatively on two-and three-dimensional displays.The diameter of the coronary sinus ostium(CSO),middle cardiac vein ostium(MCVO)and posterior vein of left ventricle ostium(PVLVO)were measured.All data was statistically processed with SPSS for Windows.Results The CS,great cardiac vein(GCV)and MCV could be clearly visualized in all of the images.1-3 branches of PVLV could be observed in 273 patients(91.0%).Small cardiac vein(SCV)and Marshall vein were found in 56(18.7%)and 24(8.0%)cases respectively.Three patients had permanent vena cava superior on the left and one patient had a CS diverticulum.Posterior descending artery(PDA)was concomitant with MCV in 189 cases(63.0%)and intersected with MCV in 96 cases(32.0%).Left circumflex artery(LCX)was concomitant with CS in 122 cases(40.7%),intersected with MCV in 15 cases(5.0%),and intersected with PVLV in 104 cases(34.7%).There were no significant differences in age,sex and CHD groups among CSO,MCV,PVLV value.The supero-inferior diameter of CSO had a significant difference between male and female(F=6.67,P<0.05).Conclusion Sixty-four slice CT venous angiography is able to be used for guiding electrophysiological procedures,which is especially useful due to the considerable variations in venous anatomy.

Objective To study the co-relation of radiological and histopathological features of lung cancer. Methods X-ray CT and histopathological features of 36 cases of lung cancer were analyzed retrospectively. Results High-density mass with strengthened edge was found to be paralleled with lung atery at lung gate in 6 cases. As a result, bronchial tubes became narrow with mucus in it. Squamous carcinoma tissues of 22 cases were showed growing within bronchial tubes. Local lung emphysema in early stage obstructive pneumonia and 19 cases of lung collapse in mid/late stage(86.4%) were brought out because of narrow cavity of bronchi. Megaly lymph nodes were seen by mediastina window in 12 cases. Peripheral mass with leaf-like edge were found in 8 cases,and the diameter of each was less than 2cm,while irregular deviated cavitative was seen in one case. Conlusion It is suggested that close combination of X-ray CT and histopathological can improve the accurate rate of diagnosis in lung cancer.
