8年间剖宫产率及指证变化的临床分析

近年来，我国各地的剖宫产率均呈明显的上升趋势，部分地区的剖宫产率甚至高达60％。居高不下的剖宫产率已引起了广大产科工作者和全社会的广泛关注。对我院近8年来剖宫产病例的临床资料进行回顾性分析，以寻求剖宫产率逐年上升的原因及探讨降低剖宫产率的途径与方法。     

Notochordal cells stimulate migration of cartilage end plate chondrocytes of the intervertebral disc in in vitro cell migration assays

Background contextIt was recently demonstrated that the postnatal transition from a notochordal to a fibrocartilaginous nucleus pulposus (NP) is accomplished exogenously by chondrocytes migrating from hyaline cartilage end plates (CEs) into the ectopic notochordal NP region. Although our previous in vivo studies showed evidences for the migration of CE chondrocyte from hyaline CEs into the notochordal NP, it is unknown whether CE chondrocytes of the intervertebral disc (IVD) really have a motile property. In addition, the effect of notochordal cells on this property has not been elucidated.PurposeThe purpose of this in vitro study was to demonstrate whether CE chondrocytes of the IVD are capable of migration, and whether there is any biological link between notochordal cells and CE chondrocytes that may regulate the CE chondrocyte migration.Study design/settingIn vitro cell migration assays were performed using rat IVDs.MethodsNotochordal cells and chondrocytes were obtained from the NP and CE tissues, respectively, and were cultured separately. The different numbers of notochordal cells and the supernatant (conditioned medium) that contained soluble factors produced by notochordal cells were used to demonstrate their effects on the migration of CE chondrocytes. Bovine serum albumin (BSA) and lysophosphatidic acid (LPA) were used as negative and positive controls, respectively.ResultsCompared with BSA, LPA, notochordal cells (N=4×, 2×, 1×, and 0.5×10⁵), and its conditioned media (unconcentrated and fivefold concentrated) significantly increased migration of CE chondrocytes (p<.05 in all comparisons). Particularly, notochordal cells and its conditioned media increased migration in a number- and concentration-dependent manner, respectively.ConclusionsThis study demonstrates that CE chondrocytes of the IVD are capable of migration and that soluble factors produced by notochordal cells stimulate the migration. These results provide a plausible explanation to the question of why CE chondrocytes of the IVD migrate into the ectopic NP region during the natural transition from the notochordal to fibrocartilaginous NP.     

ISOLATION OF VIRULENT TREPONEMA PALLIDUM FRQM HUMAN AORTA THIRTY-TWO HOURS AFTER DEATH FROM CARDIOVASCULAR SYPHILIS

After a comprehensive rernew of the literature on syphilitic aortitis, Longcope, (1) stated in 1913; ": . . . the presence of spiro: chetes in these lesions, as might be expected, cannot by any means be constantly demonstrated with Levaaiti stain. . . . . . . That these organisms are ''Treponema pallidum seems almost certain thouS:h actual proof of such by culture from the arterial lesions, a most difficult task, or direct inoculation into animals, has not as yet been accomplished."

获得性骨肥大综合征1例

获得性骨肥大综合征,即滑膜炎、痤疮、脓包疮、骨肥厚、骨炎综合征(synovitis,acne,pustulosis,hyperostosis,osteitis,SAPHO),包括骨关节病变和皮肤病变,是一种少见的原因未明的慢性进行性骨病,笔者遇到1例,现报告如下。患者男,50岁。因右胸锁关节处隆起、压痛、翻身疼痛难忍逐渐加重2年而来就诊。自述两年前曾因此处疼痛在当地医院就诊,诊为“畸形性骨炎”,用抗炎药物治疗后,症状有缓解。但近年来上述症状逐渐加重遂来本院就诊。检查:前上胸、双侧锁骨区及胸锁关节处隆起,以右胸锁关节隆起明显,局部皮肤无红、热,触诊质地硬,有压痛,无波…     

Nucleotide Sequence of the ADH23 Gene Encoding the Human Alcohol Dehydrogenase β3 Subunit

All nine exons of the ADH2(3) allele, which encodes the human alcohol dehydrogenase beta 3 subunit, have been cloned and sequenced. Comparison of this sequence to the ADH2(1) nucleotide sequence revealed only a single difference that results in an amino acid change, thus proving that the significant kinetic differences between these two isozymes is due to the Cys for Arg substitution at position 369. There are also two silent polymorphisms, and two changes in noncoding regions.
