Background: Transradial coronary angiography has established itself as safe alternative to transfemoral approach. Today, the artery of approach lies completely on the operator’s choice. The Right Radial Approach (RRA) has been a favorite for most of the interventional cardiologists due to the convenience in operating from the right side. The Left Radial Approach (LRA) has always been a neglected route. LRA does have many advantages over the right, the vascular anatomy being one of them. The aim of our study was to compare the right radial approach of diagnostic coronary angiography with left radial approach. Method: A total of 70 cases of Coronary Angiography (CAG) with normal Allen test and satisfying the inclusion criteria were prospectively observed and studied after randomly assigning them into two equal groups, LRA (Left Radial Approach) n = 35 and RRA (Right Radial Approach) n = 35. Multipurpose TIG (Tiger) catheter was used in both the approaches to catheterize the right as well as left coronary artery. Results: The access time, catheter manipulation time, procedure time, amount of contrast used, hospital stay, intensity of pain experienced, cost of the procedure and quality of coronary angiogram observed were statistically insignificant while the fluoroscopy time was slightly statistically significant which was independent to catheter manipulation time. Conclusions: The neglected Left Radial Approach to coronary angiography is as efficacious, safe and cost effective with reduction in arterial spasm complications when compared to the Right Radial Approach performed by multipurpose Tiger catheter.

HEPIS是一个新基因,关于HEPIS的表达和功能尚不十分清楚。本研究首先构建了HEPIS的表达载体pEGFP-C3-HEPIS,采用双荧光素酶报告实验检测了HEPIS对Wnt、CRE、NF-κB和HRE信号通路的作用,随后采用RNA原位杂交(RISH)检测了HEPIS在12种不同器官(乳腺,结肠,食道,肾,肝,肺,卵巢,胰腺,前列腺,直肠,胃和宫颈)的癌组织和正常组织的表达差异,并且检测了HEPIS在40例直肠腺癌和直肠正常组织的表达。研究表明,在293T细胞转染pEGFP-C3-HEPIS后,无论是转录水平还是翻译水平,HEPIS均显著增加,且HEPIS可以显著抑制Wnt、CRE和NF-κB 3条信号通路,对NF-κB信号通路的抑制最为显著。RNA原位杂交实验证实HEPIS在12个器官的癌组织和正常组织中表达存在明显的表达差异。采用GEPIA对HEPIS在直肠癌及正常组织的表达差异进行了分析,结果表明HEPIS在正常直肠组织高表达,进一步采用RISH分析了HEPIS在40例直肠癌和癌旁组织的表达差异,分析表明HEPIS在正常直肠组织的表达显著高于癌组织(P<0.01),与GEPIA分析结果一致,说明HEPIS可能是直肠癌的一个潜在抑癌基因。

Constructing type II heterostructures represents a widely recognized strategy for enhancing charge separation and photocatalytic efficiency,but it remains challenging to fabricate homologous heterostructures based on visible-light-responsive semiconductors,especially for popularly investigated （oxy）nitrides with low thermal ***,we synthesized a homologous heterostructure （denoted as YTON＿H） based on the oxynitrides of YTaO4-xNyand YTa *** heterostructure exhibits type II band structure alignment and intimate interface achieved through a magnesium （Mg） powder-assisted nitridation *** with widely reported heterologous heterostructures,the as-obtained YTON＿H homologous heterostructure could similarly exhibit enhanced charge separation as well as photocatalytic water splitting performance with respect to its counterparts(YTaO4-xNyand YTaON2).Meanwhile,detailed structural characterizations and spectroscopy analysis have been made to confirm the formation of heterostructure and promotion of spatial charge separation.

Based on analysisof karst fracture-vuggy filling mineralogy and geochemical fluorite in hercynian, this paper make further research about formation and significance of fluorite in central uplift of Tarim Basin. It is point out that the development of hercynian fracture-vuggy and filling succession of fracture-cave mineral was under the background of the mingling of low-temperature magma hydrotherm and the brine of upper strata. There are overlap or associate relations between generate of fluorite and buried dissolution or oil-gas migration. It was volume decreased 26.4% after calcite metasomatic by fluorite, this reaction made fluorite engender plentiful intergranular space. It’s created appreciable reservoir space. At same time, hydrotherm carried by fluorite generating could erode adjacent rock though fracture or fissure, forming irregular fracture-cave system, and also accompanied with hydrocarbon migration. The time of hydrocarbon migration and accumulation happened in late hercynian-indosinian is inosculates with the sedimentation time such as fluorite and several hydrothermal mineral.
