Objective: Presymptomatic gene diagnosis of autosomal dominant polycystic kidney disease families by PCR Methods: Genomic DNA were extracted Highly polymorphic microsatellite markers(SM7, AG2 5, KG8, CW2) linked to the PKD1were amplified using PCR Ten ADPKD families (104 members,including 28 affected) were analysed Results: Nine children were diagnosed with presymptomatic gene diagnosis ,although all children presented a negative ultrasonic diagnosis Conclusion: The presymptomatic gene diagnosis ...

目的：应用PCR方法对常染色体显性遗传性多囊肾病家系进行症前基因诊断。方法：用PCR扩增与PKD1位点连锁的的高度多态性的微小卫星体DNA（SM7，AC2.5，KG8，CW2）为遗传标记，对10个ADPKD家系的104个成员（包括28个患者）找出染色体上与疾病连锁的单体型，进行连锁分析。结果：对9个无临床症状，且B超检查呈阴性结果的儿童做出了症前基因诊断。结论：能够应用PCR方法对ADP－KD家系成员快速、准确地做出基因诊断

Methods from Sept 2000 to March, 2002 516 patients with body tumor were therapied. The radiotherapeutic plan and set dosage distribution had been worked out on the basis of the carcinoma position, clinical target volume, patient health condition, and therapeutic aim. The isodosage curve was 50-90%. The fractional doses was 300-900cgy. The therapy had been repeated for 5-9 times for one patient, every two days one time. Results the patients were followed up 3 to 15 months after therapy.

Objetive:To investigate the histopathological features and detect the mutation of JAK2V617F in PV、ET and IMF;to analyze the effects of the stages of myelofibrosis and the mutation on the number of leucocyte in PV and ET patients;Methods: the morphological features of 69 patients who dignosed in the first time were studied by HGF and Gomori stains ; the mutation of JAK2V617F was detected in 38 blood or marrow samples of PV、ET and IMF patients by real-time PCR;the effects of the stages of myelofibrosis and the mutation on leucocytes were analyzed;Results: Different stages of reticulin were observed in 15 PV and 15 ET patiens'marrow sections,and the cytosis、the pleomorphism and the bone trabecula side location of megakaryocytes were observed in all PV、ET and IMF patients;the means of leucocyte in patients with and without JAK2V617F were 20.4×109/Land 11.4×109/L respectively;the P value was 0.367 as comparing the leucocytes among different stages of reticulin increasing.

目的：探讨PV、ET、IMF患者的骨髓病理特点并且检测JAK2V617F突变的发生率，分析骨髓中纤维增生程度以及JAK2V617F对PV、ET患者白细胞数的影响；方法：69例初诊患者的骨髓切片经HGF染色以及Gomori染色后进行形态学研究；并利用real-time PCR法测38例患者的骨髓或者外周血的JAK2V617F突变；分析骨髓切片中纤维组织增生程度以及JAK2突变对患者白细胞数的影响；结果：15例PV和15例ET患者的骨髓切片中可以观察到不同程度的纤维组织增生，所有PV、ET、IMF患者骨髓病理中可见到巨核细胞增多、巨核细胞多形性改变以及巨核细胞定位于骨小梁旁；12例PV、4例ET、4例IMF中检测到JAK2V617F；有突变和无突变患者发病时白细胞数均值分别为20.4×109/L和11.4×109/L，比较不同纤维增生程度的PV、ET患者的白细胞数均值，P值为0.367。
