米索前列醇预防产后出血临床观察

目的探讨产妇舌下含服米索前列醇预防产后出血的效果.方法实验组100例产妇于胎头着冠时舌下含服米索前列醇600μg,对照组90例产妇于胎肩娩出后立即静脉注射缩宫素20IU.用容积法和称重法测量两组产妇的产后出血量.结果实验组产妇产后失血量平均为(116.43±94.32)ml,对照组产妇产后失血量平均为(296.52±79.41)ml,两组产妇产后失血量差异显著(P《0.01).结论舌下含服米索前列醇可有效减少产妇的产后失血量.     

Mutations in the gene encoding the basal body protein RPGRIP1L, a nephrocystin-4 interactor, cause Joubert syndrome

Protein-protein interaction analyses have uncovered a ciliary and basal body protein network that, when disrupted, can result in nephronophthisis (NPHP), Leber congenital amaurosis, Senior-L?ken syndrome (SLSN) or Joubert syndrome (JBTS). However, details of the molecular mechanisms underlying these disorders remain poorly understood. RPGRIP1-like protein (RPGRIP1L) is a homolog of RPGRIP1 (RPGR-interacting protein 1), a ciliary protein defective in Leber congenital amaurosis. We show that RPGRIP1L interacts with nephrocystin-4 and that mutations in the gene encoding nephrocystin-4 (NPHP4) that are known to cause SLSN disrupt this interaction. RPGRIP1L is ubiquitously expressed, and its protein product localizes to basal bodies. Therefore, we analyzed RPGRIP1L as a candidate gene for JBTS and identified loss-of-function mutations in three families with typical JBTS, including the characteristic mid-hindbrain malformation. This work identifies RPGRIP1L as a gene responsible for JBTS and establishes a central role for cilia and basal bodies in the pathophysiology of this disorder.

水稻花粉悬浮培养及其在育种上的应用

评估了２０个水稻品种离体花粉悬浮培养产生愈伤组织和再分化植株的能力，并进行了花粉悬浮培养试验，结果表明；品种之间反应差异很大。来源于日本的“黎明”（粳稻）最敏感。“黎明”植株再分化的频率达８４．１％。在愈伤组织的形成和植株再分化过程中，除其它一些因子外，基因型的差异有一定制约作用。通过水稻花粉悬浮培养诱导出的新品系“Ｎ１０”，其特征有：早熟，穗大，株高（９０～１００ｃｍ），产量高和抗稻瘟病等。     

Seborrhea-like dermatitis with psoriasiform elements caused by a mutation in ZNF750, encoding a putative C2H2 zinc finger protein

We describe an Israeli Jewish Moroccan family presenting with autosomal dominant seborrhea-like dermatosis with psoriasiform elements, including enhanced keratinocyte proliferation, parakeratosis, follicular plugging, Pityrosporum ovale overgrowth and dermal CD4 lymphocyte infiltrate. We mapped the disease gene to a 0.5-cM region overlapping the PSORS2 locus (17q25) and identified a frameshift mutation in ZNF750, which encodes a putative C2H2 zinc finger protein. ZNF750 is normally expressed in keratinocytes but not in fibroblasts and is barely detectable in CD4 lymphocytes.
