Objective:To study the inhibition of survivin expression by small interference RNA(siRNA) synthesized in vitro in renal cancer cell line 786-O. Methods:Three groups of survivin siRNAs were chemically synthesized in vitro and then transfected into cell line 786-O. The expression of survivin mRNA and protein after transfection were detected by reverse transcription polymerase chain reaction(RT-PCR)and Western Blotting. The proliferation of cells was detected by MTT. Results:Two sequence specific siRNAs targeting survivin down-regulated the expression of survivn mRNA and protein. The proliferation of cells was inhibited after transfection. The third one was ineffective. Conclusion:Sequence specific siRNA targeting survivin can efficiently inhibit the survivin expression and cell proliferation in renal cancer cell line 786-O. The successful application of RNAi targeting survivin might extend the list of available gene therapeutic modalities in renal cancer.

By retrieval and analysis of literature, the origin and connotation of the word Bentai were stated. In the early twentieth century, one Japanese scholar introduced the word into acupuncture-moxibustion. It was mostly used to explore the mechanism of acupuncture-moxibustion and acupoints through scientific research. One Chinese scholar introduced the connotation into acupuncture and moxibustion in 1940, and it was mainly expressed the essence. Professor ZHU Bing systematically discussed Bentai of acupoints from a scientific point of view. The knowledge of acupoints, however, is diverse, and there is different cognition due to multiple perspectives. Acupoints may not have unique Bentai.

AIM: To evaluate and analyze the morphological property and physiological activity of cartilaginous loose bodies in the knee joint, to research the changeable mechanism of histological morphous and physiological function. METHODS: The experiment was conducted at the Department of Pathology of the First Affiliated Hospital of Anhui Medical University, the Physical Testing & Chemical Analysis Center of Anhui Medical University, and the Electron Microscope Center of Anhui Provincial Hospital Affiliated to Anhui Medical University from January 2005 to January 2006. ①Experimental samples were 30 cartilaginous loose bodies all through arthroscopy as experimental group in which Group A (less than 6 months) had 14 samples and group B (between 6 and 12 months) 10, group C (more than 12 months) 6. Another 30 control samples were originated from non-weight loading side of articular cartilage through special equipment by arthroscopy. ②All samples were carried out the morphological measurement, light and transmission electron microscope exam, Ⅱ-collagen immunohistochemical stain, the measurement of collagen, calcium and fosforus. RESULTS: ①To compare the samples in the group A and control group, they had the identical or similar morphosis, microscopic structure of chondrocyte and distribution of extracellular matrix, the statistical treatments of the content of calcium, fosforus and collagen showed that the differences of scores between two groups were not statistically significant [calcium:(3.120?0.224),(3.090?0.231) mg/g;fosforus:(0.432?0.045),(0.455?0.067) mg/g;collagen:(462.43?17.12)(466.71?14.59) mg/g]. General speaking, comparing with the control articular cartilage, the loose bodies in group A had the normal histological property and physiological activity. ②Compared with control group, the samples in group B and C had the tendency of fibrous degeneration: necrotic or degenerative chondrocytes increasing, the contents of proteoglycan and Ⅱ-collagen decreasing, the tendency in group C more than group B, but the cartilaginous loose bodies in group B and C had many active chondrocytes mainly. Total content of collagen [(441.20?16.49),(417.33?8.38) mg/g] and Ⅱ-collagen decreased, while the contents of calcium and fosforus increased [calcium: (3.696?0.442),( 6.469?0.555) mg/g;fosforus:(0.523?0.068),(0.683?0.056) mg/g]. Generally, compared with the control articular cartilage, the histological property and physiological activity of the loose bodies in groups B and C had changed. CONCLUSION: The cartilaginous loose bodies can remain its histological property and physiological activity in the knee articular cavity for a long time, but it has the tendency of disorganization and physiological activity descending as time prolongs.

Heparanase (HPA) is a β-D-endoglycosidase of the only degradation of heparan sulfate proteoglycans in extracellular matrix in mammals.The related studies in recent years have suggested that HPA is closely associated with the formation and development of atherosclerotic plaques,and may be associated with the conversion from stable to unstable plaques.This article reviews the related studies of HPA in atherosclerosis progression,such as promoting plaque inflammatory response,synergy with proteolytic enzymes,and involving in hypercoagulable states,etc.

Objective To investigate the effects of ziprasidone on the hippocampal-derived neural stem cells (NSCs) viability and apoptosis injured.by LPS.Methods The NSCs were derived from the hippocampus of fetal rats,after the primary neurospheres passaged,the cells were treated with LPS (200 μg/L) and different concentrations of ziprasidone for 48 h or 72 h.The cell viability and the level of LDH were measured by the kit of WST-8 and LDH detected kit,respectively.Furthermore,the apoptosis rate of each dosage group was measured by using Annexin-V-FLUOS Staining Kit.Results (1) Cell viability test showed that the cell viability of LPS group (OD value,0.265± 0.047) was significantly reduced than that of sham (OD value,0.380± 0.029),LPS + 5 μM (OD value,0.316±0.008) and LPS+10 μM (OD value,0.321±0.006) group after ziprasidone treatment for 48 h.There were also significant difference of cell viability between sham,LPS+5 μM,LPS+ 10 μM and LPS group after ziprasidone treatment for 72 h.(2) LDH test showed that the LDH level of LPS group was significantly decreased than that of sham,LPS+5 μM and LPS+10 μM after 48 hour's ziprasidone treatment (P＜0.01).The LDH level of LPS group was also significantly reduced than that of sham,LPS+5 μM and LPS+10 μM after 72 hour's ziprasidone treatment (P＜ 0.01).(3) The apoptosis of LPS + 10 μM ((17.87 ± 2.29) ％),LPS + 5 μM ((18.45 ± 3.84) ％) treated group or sham group ((9.15 ± 1.54) ％) was significantly lower than LPS group ((22.67 ± 2.15)％) by using flow cytometry after 48 h treatment.Furthermore,the apoptosis of LPS+ 10 μM ((10.52± 1.42)％) treated group or sham group((8.45±1.04)％) was significantly lower than LPS group((15.70± 2.97) ％) after 72 h treatment.Conclusion The cellular damage of NSCs injured by LPS can be restrained by ziprasidone,and this effect might be one of the cellular mechanism of neural protective effect of ziprasidone.

Objective To study the regulating effect of in the regulation of cell surface receptor linked signal transduction pathway-related genes on rat liver regeneration(LR) at transcriptional level. Methods Genes involved in the above pathways were obtained by data collection and literature review.The gene expression changes during LR were checked by Rat Genome 230 2.0 array,and LR-related genes were identified by comparing gene expression difference between partial hepatectomy(PH) and sham operation(SO) groups. Results 491 genes were identified as LR-related.There were 742 kinds of interactive relations in 226 before-mentioned genes.In the 12 kinds of signaling pathways cytokine and chemokine mediated,enzyme linked receptor,G-protein coupled receptor,glutamate,antigen receptor-mediated,integrin-mediated,lipopolysaccharide-mediated, Notch,osmosensory,smoothened,Toll and Wnt——the numbers of up-regulated and down-regulated LR-related genes were 26 and 23,164 and 54,59 and 51,5 and 1,22 and 14,21 and 10,1 and 1,4 and 11,23 and 11, 32 and 17 respectively.In LR,the numbers of up-regulated and the down-regulated genes were 188 and 128,464 and 190,308 and 207,13 and 5,88 and 46,123 and 50,2 and 1,20 and 43,148 and 30,174 and 62 in the corresponding pathways.The genes which up regulated mainly occurred 0.5-16,30,42,54,96 hours and which down regulated mainly occurred 18-24,36,60-72,120-168 hours.Conclusion In liver regeneration,lipopolysaccharide-mediated and osmosensory signaling pathway have less effect,and the smoothened signaling pathway's role is attenuated,but the activities of the other 9 pathways are enhanced.

CCK receptor belongs to G-protein-coupled receptor (GPCR) superfamily.Polymorphism of CCK receptors can alter drug affinity and/or biological efficacy, and its genetic differences in amino acid sequences can induce ligand-independent signaling, which in turn can lead to disease. With growing efforts in the field of pharmacogenomics, it is anticipated that polymorphism-induced alterations in drug and/or receptor function will be a focus of increasing concern in the future drug-development project. Study of CCK receptor polymorphism may reveal some universal rules in GPCR superfamily. In this review, the alterations of receptor function and/or drug efficacy resulted from polymorphism in CCK receptors will be discussed in the viewpoint of molecular biology and pharmacogenomics, and some strategies in development of receptor-specific drugs will be put forward.
