甲亢性周期麻痹23例分析

目的：探讨甲亢性周期性麻痹（TPP）的临床特点。方法：对23例TPP进行回顾性分析和总结。结果：TPP占同期住院甲亢患者的6.2%,男女比例22∶1,21-40岁为发病高峰年龄,肌无力发作时23例血钾均低于正常。结论：TPP以肌无力伴低钾血症为其临床特点,及早诊治是关键。TPP患者的治疗应在补钾的同时加用抗甲状腺药物,可减少复发。对重度TPP进行心电监护、补钾、抗心律失常和呼吸机辅助呼吸是抢救成功的重要措施。

低蛋白饮食对环孢素A肾病大鼠肾间质纤维化的作用

Objective To investigate whether low-protein diet has protective effect on the progression of renal interstitial fibrosis in rats with cyclosporine A (CsA)-induced nephropathy. Methods Eighteen male Sprague-Dawley rats were randomly divided into three groups (6 rats in each group). The rats in control group (C group) received common diet; in model group (M group) low-salt diet; in intervention group (Ⅰ group) low-salt and low-protein diet. After diet adaptation period of one week, the rats in C group received subcutaneous injection of olive oil 1 mg/kg daily for 5 weeks, while M group and Ⅰ group subcutaneous injection of CsA (diluted into 25 g/L with olive oil) 1 ml/kg for 5 weeks. All the rats were sacrificed at the end of the 5th week. The food-intake and body weight were measured daily. The creatinine clearance (Ccr) was examined before rats were sacrificed. The semi-quantitative pathological analysis on kidney sections was performed. The mRNA and protein expression of transforming growth factor-β1 (TGF-βI) and type Ⅰ collagen (Col Ⅰ) in kidney tissue was determined with real time PCR and immunohistochemical staining, respectively. Results The food-intake and body weight of rats in M and I groups were significantly lower than those in C group (P<0.05). Compared with C group, the Ccr levels in M and Ⅰ groups were significantly reduced [(0.65±0.15) ml/min, (0.40+0.13) ml/min vs (1.55±0.29) ml/min, P<0.05], the relative fibrosis areas of kidney interstitium in M and I groups were significantly increased (3.60%±0.46%, 3.26%±0.75% vs 0.44%±0.24%, P<0.05), the mRNA and protein expression of TGF-β1 in M and I group was significantly up-regulated (by 2.6 and 3.1 times in mRNA and by 1.5 and 1.6 times in protein, respectively, P<0.05), and the mRNA and protein expression of Col Ⅰ in M and I groups was also significantly up-regulated (by 3.0 and 3.5 times in mRNA and by 2.3 and 2.1 times in protein, respectively, P<0.05). There were no significant differences between M and I groups in every parameters above-mentioned except the rat body weight and Ccr. Both the body weight and Ccr in Ⅰ group were significantly lower than those in M group (P<0.05). Compared with C group, the urine osmotic pressure in M group and in I group were deceased (for M group, P>0.05; for I group, P<0.05). Compared with C group, the serum cholesterol levels in M and I groups were significantly increased (P<0.05), and the serum phosphorus level in I group was significantly decreased (P<0.05). The levels of serum albumin and serum calcium of all three groups had no statistical differences (P>0.05). Conclusion Low-protein diet has no renoprutective effects on the rat model of cyclosporin A nephropathy, on the contrary, may induce body weight loss.

G蛋白耦联受体激酶结合蛋白1通过调节细胞外调节激酶1/2的活性促进成骨细胞迁移

目的探索G蛋白耦联受体激酶结合蛋白1(GITI)在成骨细胞迁移中的作用,并分析其机理。方法通过Western blot方法检测GIT1蛋白在鼠的成骨细胞内的表达；用免疫荧光染色方法确定：在血小板衍生生长因子(PDGF)不刺激和刺激的条件下,GIT1和细胞外调节激酶1/2(ERK1/2)在成骨细胞内的位置；用共同免疫沉淀的方法测定GIT1和ERK1/2相互结合,并且用免疫荧光双染的方法确定这两种蛋白相互结合的位置；用包含GIT1-RNA发夹结构的腺病毒感染成骨细胞后,用免疫荧光染色方法确定磷酸化ERK1/2(pERK1/2)在成骨细胞内的位置,用划痕愈合法检测在PDGF刺激下的迁移能力。结果在成骨细胞内,PDGF刺激导致了GIT1和ERK1/2的相互结合,并且这种结合发生在成骨细胞的局部粘附内。包含GIT1-RNA发夹结构的腺病毒明显抑制了pERK1/2招募至成骨细胞局部粘附内以及PDGF所刺激的成骨细胞的迁移。结论在PDGF刺激下,GIT1招募pERK1/2至成骨细胞的局部粘附内,从而促进成骨细胞的迁移。
