Bilateral complete discoid medial meniscus combined with posterior cyst formation

Bilateral discoid medial menisci is an extremely rare condition of the knee and it can be associated to other pathological findings, including anterior portion cyst formation. We report on the clinical features, radiographic findings, treatment and results of one patient who presented a bilateral medial discoid meniscus combined with posterior portion cyst of the left knee. To the best of the author’s knowledge, this is the first case of bilateral medial discoid meniscus associated with posterior portion cyst formation.     

子宫肌瘤与细胞凋亡的研究

目的:探讨子宫平滑肌瘤的发生与细胞凋亡的关系.方法:采用凝胶电泳技术对子宫平滑肌瘤患者的肌瘤核组织(实验组)及其周围的正常肌组织(对照组)进行DNA片段分析;采用碘化丙啶(PI)对DNA染色,流式细胞仪检测两组细胞的凋亡率,进行细胞凋亡的定量分析.结果:实验组有9例出现DNA断裂的梯形条带(9/30,30.0%),对照组有20例出现DNA梯形条带(20/30,66.7%),二者比较有明显差异;实验组凋亡率明显低于对照组.结论:子宫肌瘤的发生与细胞凋亡异常有关.     

The prevalence of LRRK2 Gly2385Arg variant in Chinese Han population with Parkinson's disease.

We conducted a case-control study to determine the prevalence of the LRRK2 Gly2385Arg variant in patients with Parkinson's disease in Han population in mainland China. Heterozygous LRRK2 Gly2385Arg variant was identified in 14 of 235 patients with Parkinson's disease (5.69%), but not in 214 unrelated healthy controls. Multivariate analysis indicated the frequency of Gly2385Arg variant in the female patients with early age at onset is higher than their male counterparts. The founder haplotype analysis showed the variant carriers shared the same founder. Clinically, the LRRK2 Gly2385Arg carriers presented with classical Parkinson's disease symptoms. Our study indicates that the LRRK2 Gly2385Arg variant is a potential ethnic-specific genetic risk factor of Parkinson's disease within Chinese Han ethnicity.

移植肾血管痉挛原因探讨

通过对临床37例肾移植的观察，发现术中移植肾开放血流后肾血管痉挛现象与当时血压明显相关。收缩压大于24kPa者，移植肾血管痉挛率为53．33％，收缩压低于24kPa者，移植肾血管痉挛率为9．09％。两组有显著性差异（P＜0．01）．发生血管痉挛的肾脏排尿时间较未痉挛者明显延长，分别为23±6．35min．3．8±0．86min，两组差异极显著（P＜0．01）．从而认为肾移植术中提升血压应适度，并针对移植肾血管痉挛的原因进行了讨论。     

基因治疗帕金森病的实验研究

本研究把Ⅰ型人酪氨酸羟化酶(human tyrosine hydroxylase type Ⅰ;HTH_1)cDNA连接到逆转录病毒载体LNSX上,构建成真核表达载体 LNSHTH_1,然后通过in vivo途径转染帕金森病模型鼠的纹状体细胞。外源的HTH_1基因在宿主脑内得到了表达,并使其病理行为改善约70％。这种新的基因治疗帕金森病的方式,有其独特的优越性。     

儿童感觉统合失调及其影响因素的调查分析

目的 研究儿童感觉统合失调与学习障碍及环境因素的关系。方法 采用感觉统合评定量表和学习障碍(PRS)筛查量表，分别对755名学龄儿童进行检测、分析。结果 感觉统合严重失调率为13．25％；感觉统合正常与失调儿童的学习障碍有统计学差异(P＜0．005)；其中在LD儿童中感觉统合失调率占63．51％；感觉统合失调与母孕期的情绪、是否足月顺产、出生后的喂养方式、居住环境、孩子1岁内有无高热、家长对孩子的态度及期待等因素有关(P＜0．05)。结论 儿童感觉统合失调与环境因素、学习障碍有一定的关系。
