Objective To investigate the application value of a new type of mesh density basket in cleaning and disinfection of small dental equipment. Methods Totally 120 root canal files were randomly divided into the observation group and control group, with 120 files in each group. The stainless steel mesh cup was used in cleaning and disinfection of small dental equipment in the control group, while a new type of mesh density basket was used in the observation group. The quality of cleaning was measured, and the sharp instrument injuries were retrospectively analyzed within 1 year. Results The rate of qualified cleaning was 98. 33%(59/60) in the observation group, which was higher than 85. 00%(51/60) in the control group(P

The major monomer and oligomer of proanthocyanidins from the petals, seeds, fruits or pericarps of 11 plants were detected, and the difference of proanthocyanidin contents were analyzed in a variety of plants in this study. The catechin(C), epicatechin(EC), gallic acid(GA), procyanidin B2 (PCB2), procyanidin B4(PCB4), procyanidin A2(PCA2) of the 11 plants were extracted by 85% ethanol solution under ultrasonic, purified by Oasis PRiME HLB solid phase extraction column and separated by high performance liquid chromatography(HPLC). The result showed that monomers or oligomers of proanthocyanidins could be detected in 11 plants under the selected chromatographic conditions, and the content was mainly proanthocyanidin oligomers(OPC). Among them, the content of proanthocyanidins in grape seeds was the highest and the types were the most. Six proanthocyanidin monomers and oligomers were all detected in grape seeds. Two monomers, C and GA, and three oligomers, PCB2, PCB4 and PCA2, were detected in rose petals and peanut seed coats, respectively. In blueberry, walnut kernel, lycium ruthenicum murray and purple cabbage, except one proanthocyanidin monomer was detected, three kinds of proanthocyanidin oligomers were detected in blueberry and walnut kernel, while only PCB2 and PCB4 were detected in lycium ruthenicum murray and purple cabbage. The pericarp of red potato and purple potato only had OPCs; and the types of proanthocyanidin monomers and oligomers in red pepper and pericarps of dragon fruit were few and the content was low. In addition, the seed and pericarp of grape, peanut kernel and its seed coat were different parts of the same plant, and the types and content of proanthocyanidins were different. The types and contents of proanthocyanidins in different plants were different. The types and contents of proanthocyanidins in different parts of the same plant were also different. The differences of distribution, composition and concentration of proanthocyanidins in different plants lay a foundation for the study of structure-activity relationship and its development and utilization.

卵圆孔未闭 (PFO) 是一种先天性心脏病, 在成人中的发病率为 20%～25%。诸多研究表明, PFO 与多种病理状态明显相关, 包括隐源性中卒中 (CS)、短暂性脑缺血发作 (TIA)、不明原因的晕厥、减压病、偏头痛、急性冠脉综合征等。随着超声技术的发展, 多种超声技术联合应用使 PFO 诊断阳性率不断提高, 对 PFO 形态、解剖结构判断更为精确。目前研究表明, 对 PFO 患者进行封堵手术干预可降低卒中复发风险并可能缓解偏头痛症状。国际上应用的封堵器在安全性和有效性上基本相似。 [ABSTRACT FROM AUTHOR]
