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.

Objective To explore the cognition impairment of Parkinson's disease (PD) subtypes and the risk factors for cognitive dysfunction.Methods Totally56 patients with PD and 30 control subjects were selected.All patients were assessed by Mini-Mental State Examination (MMSE),the Montreal cognitive assessment scale (MoCA),digital span test scale (DS),block design test scale (BD).The cognition impairment status of PD subtype was compared between the two groups.Risk factors for cognitive impairment in Parkinson's disease were analyzed by the multiple regression analysis.Results The scores (or accuracy) of visuospatial / executive function,memory,repeat,attention,animal naming,understanding,calculation,orientation in PD patients and control group were (29.84±13.78) and (44.63±10.95),(17.64±3.00) and (21.93±2.12),(1.64±0.90) and (2.40±0.62),64.29％ and 86.67％,(2.25±0.77) and (2.70±0.47),(2.66± 0.67) and (2.93±0.25),(3.98±1.17) and (4.93±0.25),(9.59±0.68) and (9.93±0.25) respectively,and there were statistically significant differences in above indictors between two groups (t=-5.080,-7.707,-4.571,-3.374,-2.710,-5.844,-3.367,respectively,x2 =4.86,all P＜0.05).Pearson correlation analysis showed that the cognitive function had a positive correlation with education status,had negative correlations with duration of disease,Unified Parkinson's Disease Rating Scale (UPDRS)-Ⅲ,Hoehn and Yahr (H-Y) staging,Hamilton Anxiety Scale (HAMA),Hamilton Rating Scale for Depression (HRSD) (MMSE:r=0.488,-0.682,-0.478,-0.465,-0.611,-0.538,respectively,all P＜0.05,MoCA:r=0.553,-0.583,-0.396,-0.384,0.499,-0.444,respectively,all P＜0.05),and had no correlation with gender,age,age of onset.Taking the duration of disease,education status,UPDRS-Ⅲ,H-Y grade,HAMA,HRSD as the independent variable,MMSE,MoCA as the dependent variable,multiple linear regression analysis showed that only the duration of disease and education status had effects on cognitive dysfunction in PD (MMSE:β=-0.042,0.196,both P=0.000,MoCA:β=-0.052,0.367,both P＜0.05).Conclusions The key points of cognition impairment in PD patients are the impairments in visuospatial/ executive function,memory,repeat,attention,animal naming,understanding,calculation and orientation.The duration of disease and low level of education are the risk factors for cognitive dysfunction in patients with Parkinson's disease.

BACKGROUND:With the development of sports medicine and research of patel ofemoral disorder, patel a alta has been paid increasing attention as the exact pathogenesis of patel ofemoral disorder. There are many radiographic measurement indexes of patel a alta. A large number of clinicians and radiography physicians are trying to diagnose and treat this disease as early as possible.
OBJECTIVE:To review the radiographic measurement and research progress of patel a alta, find out the advantages and disadvantages of different indexes, and look into the future development prospects.
METHODS:A computer-based online search of Pubmed and CNKI databases between 1989 and 2013 was performed for articles addressing radiographic diagnose and measurement patel a alta. The key words were“patel a alta, patel a height, measurement, diagnosis”in English and“patel a alta, patel a height, patel a position, diagnosis, measurement”in Chinese.
RESULTS AND CONCLUSION:Now there are many measurement indexes of patel a alta and they are divided into two groups:indirect index and direct index. The indirect index measures the relative location of patel a and tibia, such as Insal-Salvat index, Blackburne-Peel index, and Caton-Deschamps index. The direct index measures the relative location of patel a and femur, such as patel otrochlear index, and patel ophyseal index. The latest study indicates that the biomechanics of patel ofemoral joint is the key to understand the pathogenesis of patel ofemoral disorder. As the MRI technique develops, direct index for the location of articular cartilage of patel ofemoral joint, such as patel otrochlear index, seems to be the best measurement to patel a alta. However we stil have many problems in the study of patel otrochlear index.

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.

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.

Traditional operation for esophageal cancer includes esophagectomy and digestive tract reconstruction,which is associated with more postoperative complications and high mortalities due to severe trauma.Endoscopic surgery(including thoracoscope,mediastinoscope,and laparoscope) for radical resection of esophageal cancer has mild operative trauma,less bleeding and mild postoperative pain,resulting in less postoperative complications and low mortalities.This article analyzes the current status of endoscopic surgery in radical operation of esophageal cancer and the existing problems,providing reference for the development of minimally invasive surgery of esophageal cancer.

Lycobetaine ( AT-1840 ) is an effective antitumor substance. In the present work it was demonstrated that in a dose of 40 pig/kg AT-1840 could decrease the percentage of G, cells, meanwhile it increased G2 + M cells remarkably by means of flow fluocytometry method, AT-1840 could also inhibit the progression of cells from G2 to G1 phase. 8 to 72 h after, the injection the mitotic index was decreased significantly and recovered gradually in 6 d. It could inhibit the prophase and metaphase greatly, but had no marked influence on anaphase & telophase.

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.
