Genetic linkage analysis of pulmonary fibrotic response to silica in mice.

Inter-individual variations in the development of silicosis, even within the same environments, have been reported, which suggest the contribution of genetic factors in silicosis aetiology. The aim of the present study was to determine whether there is any significant genetic influence on the development of silicosis. Furthermore, which genetic loci are responsible for the pulmonary response to silica exposure? Eight strains of inbred mice were used to examine the genetic influence on the lung fibrotic response to silica exposure. After intercross-breeding between the most susceptible and most resistant strains, a genome-wide linkage analysis of quantitative trait loci (QTL) was performed. Hydroxyproline was applied as an index, and genotypes of 167 marker genes were analysed by fragment analysis using a capillary-type sequencer. There was significant inter-strain difference in the mean concentration of hydroxyproline contents among the eight strains of mice. Breeding studies were conducted between the most susceptible, C57BL/6J, and the most resistant strain, CBA/J. A genome-wide linkage analysis of silica-exposed intercrossed cohorts identified significant QTL on chromosome 4 and suggestive QTL on chromosomes 3 and 18. The present study demonstrates that genetic factors may play a significant role in fibrotic-lung responses to silica; one significant and two suggestive quantitative trait loci were identified.     

Non-invasive Assessment of Coronary Flow Velocity Reserve: A New Method Using Transthoracic Doppler Echocardiography

Coronary flow reserve (CFR) has been used toassess coronary microcirculation and epicardial coro-nary stenoses[1— 3 ] . CFR is defined as the ratio ofcoronary flow under maximal coronary vasodilatationto coronary flow under resting conditions[4 ] .Whenthe cross- sectional area of epicardial coronary arteriesis constant,coronary flow velocity (CFV) ratios areequal to volume flow ratios.The most common method used clinically formeasuring CFVR is intracoronary Doppler flow(ICD) analysis re…     

晶体玻璃体视网膜联合手术治疗复杂性视网膜脱离

目的探讨玻璃体视网膜手术（ｖｉｔｒｅｒｅｔｉｎａｌｓｕｒｇｅｒｙ，ＶＲ术）联合晶体切除／超声粉碎的效果。方法对８１例（８１只眼）应用晶体玻璃体视网膜联合手术（ｌｅｎｔｉｃｕｌａｒ－ｖｉｔｒｅｏｒｅｔｉｎａｌｓｕｒｇｅｒｙ，ＬＶＲ术）治疗的复杂性视网膜脱离进行回顾性分析。结果解剖性成功者６４只眼（７９．０１％），功能性成功者４５只眼（５５．５６％）；手术成功率显著降低的原因是前部增殖性玻璃体视网膜病变（ｐｒｏｌｉｆｅｒａｔｉｖｅｖｉｔｒｅｏ－ｒｅｔｉｎｏｐａｔｈｙ，ＰＶＲ）（成功率４２．８６％，Ｐ＜０．０１）和术中／术后眼内出血（成功率５８．８２％，Ｐ＜０．０２５）。结论ＬＶＲ术是治疗复杂性视网膜脱离的主要方法；显著影响手术预后的因素是前部ＰＶＲ和术中／术后眼内出血。     

Evidence that the Receptor for Soluble CD14:LPS Complexes may not be the Putative Signal-Transducing Molecule Associated with Membrane-Bound CD14

Membrane-bound CD14 acts as a receptor for lipopolysaccharide (LPS) on monocytes/macrophages and neutrophils. Studies have suggested that the activation of monocytes/macrophages by the binding of LPS to membrane-bound CD14 may require the association of a signal-transducing molecule with membrane-bound CD14. The observation that non-CD14 expressing cells, such as endothelial cells, can nevertheless be activated by a complex of LPS and a soluble form of CD14 (sCD14) suggests that the receptor for this complex may be identical to the signal transducing molecule associated with membrane-bound CD14. The studies described show that two CD14-specific MoAb are able to block the LPS-induced activation of endothelial cells but do not affect the response of monocytes to LPS. This suggests that the interaction of the sCD14:LPS complex with endothelial cells is distinct from the interaction of membrane-bound CD14 with its putative signal-transducing molecule.     

外阴汗腺癌七例临床分析

目的：总结外阴汗腺癌的临床特点及治疗方法。方法：对７例外阴汗腺癌病例进行回顾性分析。结果：外阴汗腺癌的发病年龄为４０～５８岁。７例患者的治疗为局部扩大切除或根治性外阴广泛切除，２例辅以术后放疗。７例中５例存活５年以上，其中１例曾在首次治疗后第７年、１１年２次复发并于第１７年死于肿瘤。２例存活＜５年，１例在术后２年半死于脑出血，１例因脊椎广泛转移在术后１年零９个月死亡。结论：外阴汗腺癌的预后较好，局部扩大切除或根治性外阴切除，是首选治疗方法。
