尝试利用二次离子质谱(SIMS)技术,采用国家一级标样(GBW04481)oka方解石和美国威斯康星大学标样UWC-3方解石,对长江中游清江和尚洞洞穴碳酸盐沉积物hS4石笋的8.3ka BP时段(236.3~235.6 cm)进行了季节分辨率的?18O原位分析,探讨了利用季节分辨SIMS?18O所呈现出的年际旋回对石笋进行相对定年的可能性;并通过SIMS法与常规法?18O值的比较,分析了两者间偏差产生的可能原因.以oka作外标,利用Cameca IMS 1280离子探针在3个工作日内对UWC-3进行了氧同位素分析,获得的测量结果(?18OVPDB=?17.85‰±0.22‰,1SD)与其推荐值(?18OVPDB=?17.83‰?0.08‰)在误差范围内一致,说明仪器稳定性良好、测试方法可靠.用SIMS法获得的hS4石笋?18O季节分辨率记录,则呈现出较为显著的年际旋回特征,其旋回总数与同段石笋Mg/Ca比及石笋反光微层图像中所呈现出的年层总数一致,有望为不具备清晰年纹层石笋的相对定年提供一个新的方法.与常规法?18O分析结果相比,hS4石笋SIMS法?18O值系统偏负0.90‰,且季节性差异增大,其主要原因可能是缘于样品中细微裂隙、孔洞和包裹体的存在,同时亦不排除石笋中有机质的存在对SIMS?18O值可能造成的影响,说明要获得与常规法?18O值相符的SIMS?18O值记录,石笋样品的致密度和纯净度均至关重要.

Focal segmental glomerulosclerosis (FSGS) is characterized histologically by hyalinosis and sclerosis of glomeruli associated or not with podocyte involvement. The objective of our work was to clarify the epidemiological aspects and histological variants of FSGS in Côte d’Ivoire. Materials and Methods: This was a descriptive retrospective study, conducted from January 2015 to December 2019 using the renal biopsy registers (RB) of the Pathological Anatomy and Cytology departments of the Teaching hospital of Cocody and Bouake in collaboration with the Nephrology Services of Côte d'Ivoire and the sub-region. The biopsies underwent conventional histopathology and/or immunofluorescence techniques. The parameters analyzed were: frequency, age, gender, proteinuria, biopsy indications and histological aspects and the different correlations between histological aspects and socio-demographic characteristics. Results: FSGS represented 58.1% (n = 104) of glomerular nephropathies. The average age of patients was 32.1 ± 13.3 years, with extremes of 13 and 70 years. The sex ratio was equal to 1. Nephrotic syndrome (68.9%), chronic renal failure (14.3%) and acute renal failure (10.1%) were the main indications for renal biopsy (RB). The mean proteinuria at the time of diagnosis was 4 ± 3.7 g/24 h. It was massive (3.5 g/24 h) in 42.3% of patients. FSGS was primary in 29.8% (n = 31) and secondary in 70.2% (n = 73) of patients, of which 27.9% (n = 35) was due to hIV. According to the Columbia classification, 62.5% NOS type was found;23.1% collapsing type;7.7% tip lesion type;4.8% cell type and 1.9% perihilary type. Conclusion: FSGS is a complex heterogeneous entity. It affects young people in our context with a homogeneous gender distribution. Understanding its histogenesis is essential for optimal patient management.

Xeroderma pigmentosum group C (XPC) protein is specifically involved in a subpathway of mammalian nucleotide excision repair (NER) operating genome-wide. The XPC protein is tightly complexed with hR23B, one of two mammalian homologs of a yeast NER factor, Rad23. Although the XPC-hR23B complex exhibits a high affinity for DNA, its

作者： Sakimoto S. Gomi F. Sakaguchi h. Tano Y. 宋虎平 Department of Ophthalmology Osaka University Medical School 2-2 Yamada-oka Suita Osaka 565-0871 Japan Dr.

PURPOSE: To report a case of retinal angiomatous proliferation (RAP) treated by ablation of the feeding and draining vessels that recurred by 6 months postoperatively. DESIGN: Interventional case report. METhODS: Images from fluorescein angiography, indocyanine green (ICG) angiography, and optical coherence tomography (OCT) were examined before and after ablation. RESULTS: The hot spot on late-phase ICG, the leakage on fluorescein angiography, the pigment epithelial detachment, and macular edema on OCT decreased postoperatively. however, a large hyperfluorescent lesion was detected on ICG 6 months postoperatively with recurrent cystoidmacular edema. CONCLUSIONS: A new RAP lesion can develop even after the original lesion seemed to resolve after ablation.
