1精索静脉曲张病人双侧睾丸组织学研究和减数分裂分析显示文摘50例男性在进行精索静脉曲张结扎手术时作双侧睾丸活俭。活检组织用Johnscn得分法作组织学研究,另分一部分作减数分裂分析。所有病人术后都进行随访,,平均随访时间为19.3月,并追踪他们配偶的怀孕情况。研究表明,精索静脉曲张没有特异的组织学或减数分裂异常,也没有证据表明曲张侧睾丸病变比对侧更严重。13例妻子怀孕,这些病例至少有一侧睾丸Jobnsen得分大于7.0,我们认为采用双侧睾丸活检可预测精索静脉曲张手术的效果。王益鑫 Chandley Ann C Macintyre Margaret Hargreave Timothy B 1991男性学杂志1991,5,1:12
2Are hyoliths Palaeozoic lophophorates?显示文摘The phylogenetic position of hyoliths has long been unsettled,with recent discoveries of a tentaculate feeding apparatus('lophophore')and fleshy apical extensions from the shell('pedicle')suggesting a lophophorate affinity.Here,we describe the first soft parts associated with the feeding apparatus of an orthothecid hyolith,Triplicatella opimus from the Chengjiang biota of South China.The tuft-like arrangement of the tentacles of T.opimus differs from that of hyolithids:suggesting they collected food directly from the substrate.A reassessment of the feeding organ in hyolithids indicates that it does not represent a lophophore and our analysis of the apical structures associated with some orthothecids show that these represent crushed portions of the shell and are not comparable to the brachiopod pedicle.The new information suggests that hyoliths are more likely to be basal members of the lophotrochozoans rather than lophophorates closely linked with the Phylum Brachiopoda.Fan Liu Christian B Skovsted Timothy P Topper Zhifei Zhang Degan Shu 2020National Science Review2020,7,2:5
3Distribution of pericellular matrix molecules in the temporomandibular joint and their chondroprotective effects against inflammation显示文摘The objectives of this study were to(1) determine the distribution and synthesis of pericellular matrix(PCM) molecules(collagen VI, collagen IV and laminin) in rat temporomandibular joint(TMJ) and(2) investigate the effects of PCM molecules on chondrocytes against inflammation in osteoarthritis. Four zones(fibrous, proliferating, mature and hypertrophic) of condylar cartilage and three bands(anterior, intermediate and posterior) of disc were analysed by immunohistochemistry for the presence of PCM molecules in rat TMJs. Isolated chondrocytes were pre-treated with PCM molecules before being subjected to interleukin(IL)-1β treatment to stimulate inflammation. The responses of the chondrocytes were analysed using gene expression, nitric oxide release and matrix metalloproteinase(MMP)-13 production measures. Histomorphometric analyses revealed that the highest areal deposition of collagen VI(67.4%), collagen IV(45.7%) and laminin(52.4%) was in the proliferating zone of TMJ condylar cartilage. No significant difference in the distribution of PCM molecules was noted among the three bands of the TMJ disc. All three PCM molecules were expressed intracellularly by chondrocytes cultured in the monolayer. Among the PCM molecules, pre-treatment with collagen VI enhanced cellular proliferation, ameliorated IL-1β-induced MMP-3, MMP-9, MMP-13 and inducible nitric oxide synthase gene expression, and attenuated the downregulation of cartilage matrix genes, including collagen I, aggrecan and cartilage oligomeric matrix protein(COMP). Concurrently, collagen VI pretreatment inhibited nitric oxide and MMP-13 production. Our study demonstrates for the first time the distribution and role of PCM molecules, particularly collagen VI, in the protection of chondrocytes against inflammation.Wern Cui Chu Shipin Zhang Timothy J Sng Yu Jie Ong Wen-Li Tan Vivien Y Ang Casper B Foldager Wei Seong Toh 2017International Journal of Oral Science2017,9,1:5

5Meeting report:a hard look at the state of enamel research显示文摘The Encouraging Novel Amelogenesis Models and Ex vivo cell Lines(ENAMEL) Development workshop was held on 23 June 2017 at the Bethesda headquarters of the National Institute of Dental and Craniofacial Research(NIDCR). Discussion topics included model organisms, stem cells/cell lines, and tissues/3 D cell culture/organoids. Scientists from a number of disciplines,representing institutions from across the United States, gathered to discuss advances in our understanding of enamel, as well as future directions for the field.ophir d klein olivier duverger wendy shaw rodrigo s lacruz derk joester janet moradian-oldak megan k pugach j timothy wright sarah e millar ashok b kulkarni john d bartlett thomas gh diekwisch pamela den besten james p simmer 2017International Journal of Oral Science2017,9,4:3
6Total pancreatectomy: Short- and long-term outcomes at a high-volume pancreas center显示文摘AIM To identify the current indications and outcomes of total pancreatectomy at a high-volume center. METHODS A single institutional retrospective study of patients undergoing total pancreatectomy from 1995 to 2014 was performed.RESULTS One hundred and three patients underwent totalpancreatectomy for indications including: Pancreatic ductal adenocarcinoma(n = 42, 40.8%), intraductal papillary mucinous neoplasms(n = 40, 38.8%), chronic pancreatitis(n = 8, 7.8%), pancreatic neuroendocrine tumors(n = 7, 6.8%), and miscellaneous(n = 6, 5.8%). The mean age was 66.2 years, and 59(57.3%) were female. Twenty-four patients(23.3%) underwent a laparoscopic total pancreatectomy. Splenic preservation and portal vein resection and reconstruction were performed in 24(23.3%) and 18 patients(17.5%), respectively. The 90 d major complications, readmission, and mortality rates were 32%, 17.5%, and 6.8% respectively. The 1-, 3-, 5-, and 7-year survival for patients with benign indications were 84%, 82%, 79.5%, and 75.9%, and for malignant indications were 64%, 40.4%, 34.7% and 30.9%, respectively.CONCLUSION Total pancreatectomy, including laparoscopic total pancreatectomy, appears to be an appropriate option for selected patients when treated at a high-volume pancreatic center and through a multispecialty approach.Hazem M Zakaria John A Stauffer Massimo Raimondo Timothy A Woodward Michael B Wallace Horacio J Asbun 2016World Journal of Gastrointestinal Surgery2016,8,9:3
