急诊科严重胸外伤病人的呼吸管理

对36例严重胸外伤病人加强呼吸管理，其中34例病人呼吸困难改善，抢救成功率为94.4％。从护理的角度讨论了呼吸机应用、气道管理、呼吸监测、镇静剂应用等在抢救严重胸外伤病人过程中的作用。由此认为加强呼吸管理是抢救严重胸外伤病人的关键。

推拿、穴位注射配合电针治疗颈椎病

近几年来我们采用推拿、穴位注射配合电针治疗颈椎病收到了较好的效果,现报道如下. 一般资料 本组病例共60例,其中门诊40例,住院20例;     

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。     

宫腔镜引导疏通输卵管治疗阻塞性不孕

目的在宫腔镜引导下疏通输卵管治疗阻塞性不孕。方法选择经子宫输卵管造影证实不同程度的输卵管阻塞120例，于月经干净3-7d进行输卵管疏通术治疗（地塞米松注射剂5mg，庆大霉素注射剂8万U，糜蛋白酶注射剂4000U）。结果单侧输卵管治疗有效率83．9％，有改善16．1％。双侧输卵管阻塞治疗有效率51．4％，有改善18．9％，无效29．7％。结论官腔镜引导下能准确判断左右两侧输卵管开口的位置及治疗情况，提高了一次疏通命中率及治愈率，是一种微创、安全、有效的治疗方法。     

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.
