自制新荧光剂EPQS的性能测试

作者对自制新荧光剂EPQS进行了性能测试。结果:量子产率为0.21;最大激发波长和荧光波长分别为375nm和484nm,stokes位移109nm;检测生物化合物常用的缓冲溶液对荧光峰位无影响,对荧光强度影响很小;温度的影响也小(18～43℃,FRI61.5～58.1),PH的影响也不大。说明EPQS不仅荧光参数好,而且稳定性也好。适合在较广泛的环境条件下使用。     

Solitary Small Hepatic Angiosarcoma: Initial and Follow-up Imaging Findings

We report an uncommon case of solitary, small hepatic angiosarcoma that was initially considered as a hemangioma. We present the imaging findings, with an emphasis on the initial and follow-up CT and MR findings, as well as report on the more suggestive findings of angiosarcoma than those of a hemangioma.     

Access to primary health care for Australian young people: service provider perspectives.

BACKGROUND: To adequately address the complex health needs of young people, their access to services, and the quality of services received, must be improved. AIMS: To explore the barriers to service provision for young people and to identify the training needs of primary healthcare service providers in New South Wales (NSW), Australia. DESIGN OF STUDY: A cross-sectional, qualitative study of the perspectives of a range of health service providers. SETTING: A range of primary healthcare organisations across NSW. METHODS: Samples of general practitioners (GPs), youth health workers, youth health coordinators, and community health centre staff were drawn from urban and rural clusters across NSW. Focus groups and interviews were used to identify barriers to service provision and the training needs of service providers. Data were tape recorded, transcribed, and analysed. RESULTS: Barriers to service provision among GPs and community health centre staff included inadequate time, flexibility, skills, and confidence in working with young people, and poor linkages with other relevant services. Training needs included better knowledge of and skills in adolescent health requirements, working with adolescents, and working with other services. Barriers to service provision for youth health workers and coordinators included lack of financial resources and infrastructure. There were few linkages between groups of service providers. CONCLUSION: Models of service provision that allow stronger linkages between service providers, sufficient time for consultation with young people, adequate training and support of health professionals, and flexibility of service provision, including outreach, should be explored and evaluated.     

移植肾组织TGF-β1和MMP-2表达及IV型胶原沉积与慢性移植肾肾病的关系

目的 探讨移植肾组织中转化生长因子β1(TGF-β1)和基质金属蛋白酶2(MMP-2)的表达及IV型胶原沉积与慢性移植肾肾病(CAN)的关系.方法 对18例CAN患者进行了移植肾切除术.光镜下观察切除的肾组织标本并根据其纤维化的程度进行分期,用免疫组织化学技术和图像分析法检测移植肾组织中TGF-β1和MMP-2表达量及IV型胶原沉积情况,并分析患者血肌酐(Cr)和尿素氮(BUN)的水平与移植肾纤维化程度的关系.结果 随着患者移植肾纤维化程度的加重,血清肌酐、尿素氮及肾组织中TGF-β1、IV型胶原基因表达量均增加,MMP-2表达量于移植肾纤维化早期明显升高,并随移植肾纤维化程度加重而逐渐降低.结论 移植肾组织中TGF-β1表达量增高及IV型胶原沉积可以促进CAN的进程,而MMP-2则可抑制其进展.     

壮骨肾宝对实验性小鼠高脂血症的影响

目的观察由黄芪、白术、淫羊藿组成的复方制剂(壮骨肾宝)对实验性小鼠高脂血症的影响。方法用蛋黄乳液快速致小鼠单纯性高胆固醇血症和喂养高脂饲料致高脂血症模型 ,观察预防性给予不同剂量的壮骨肾宝后对血清总胆固醇(TC)、甘油三酯(TG)和高密度脂蛋白胆固醇(HDL -ch)的影响。结果壮骨肾宝中、高剂量能使血清TC降低(P<0.05),HDL -ch升高(P<0.01) ,但对TG的影响不大。结论壮骨肾宝有一定降血脂作用 ,并与剂量有关

THE HISTOLOGIC FEATURES AND HISTOGENESIS OF MALIGNANT OVARIAN BRENNER TUMOR

Eight cases of malignant and 12 0f benign Bren- ner tumor are reported, patient ages ranged 31 69 and 39-53 years. The malignant tumor was bilateral in 6 0f 8 cases, and the benign in l of 12. The greatest diameter of the malignant tumors averaged around 11 cm, and the benign 10. Six of the malignant Brenner tumor patients died, one was lost to follow up, and one survived for 10 years. Pathologic and microscopic findings were pre- sented in some detail. Based on the analysis of the association between the histologic features and type of Mullerian epithelium, we believe that the so called Brenner tumor is in effect a tumor arising from the Mullerian epithelium with a tendency to differentiate into vaginocervical type epithelium.     

介入手术治疗异位妊娠12例临床分析

目的：探索一种治疗输卵管妊娠的微创介入手术，解决因其腹腔出血不能接受保守治疗或保守治疗失败的难题。保持输卵管完整及通畅，满足有生育需求的患。方法：对12例输卵管妊娠妇女行对侧股动脉穿刺，将导管超选择插至子宫动脉以甲氨喋呤(MTX)进行灌注及明胶海绵栓塞术。结果：本组病例中，术后10dB超复查孕囊脱落、吸收消失，栓塞后盆腔活动性出血停止。结论：介入治疗宫外孕输卵管妊娠，能有效杀灭胚胎组织，栓塞破裂血管止血效果明显，且能保持输卵管通畅。
