壮骨肾宝对实验性小鼠高脂血症的影响

目的观察由黄芪、白术、淫羊藿组成的复方制剂(壮骨肾宝)对实验性小鼠高脂血症的影响。方法用蛋黄乳液快速致小鼠单纯性高胆固醇血症和喂养高脂饲料致高脂血症模型 ,观察预防性给予不同剂量的壮骨肾宝后对血清总胆固醇(TC)、甘油三酯(TG)和高密度脂蛋白胆固醇(HDL -ch)的影响。结果壮骨肾宝中、高剂量能使血清TC降低(P<0.05),HDL -ch升高(P<0.01) ,但对TG的影响不大。结论壮骨肾宝有一定降血脂作用 ,并与剂量有关     

角膜溃疡穿孔的修复与修复材料的选择

总结２１例用不同材料修复角膜穿孔的病例，修复材料分别为结膜瓣、硅胶板、断层自体皮片和同种异体角膜。结膜瓣遮盖仅２／３保存眼球，愈合后视力差，并发症多；硅胶板可在穿孔大、情况紧急时作暂时封孔保存眼球之用；自体断层皮片术后不久即溶解，角膜移植者７眼中６眼保存了眼球，且有５例植片透明，视力０．１以上。     

Whole CanA Gene Amplification of Helicobacter pylori and Its Fingerprinting by Restriction Fragment Length Polymorphism

To set up a method of amplification for the whole CagA gene of Helicobacter pylori and its fingerprinting by restriction fragment length polymorphism(RFLP),nested PCR was employed in combination with TD-PCR to amplify the gene and EcoRI and Hind Ⅲ were used to generate the RFLP fingerprinting.Target DNA fragments from 13 of 20 samples were successfully amplified and the relevant RFLP fingerprintings were obtained.It is concluded that the method can be used to amplify the whole CagA gene and CagA gene has apparent diversity of RFLP profile.     

大豆蛋白影响肾损害模型钙摄入和钙排出的实验研究

[目的]研究大豆蛋白对肾损害大鼠钙平衡的影响。[方法]选择3月龄断乳雄性SD大鼠40只．按体质量从小到大排序，采用完全随机化原则分为4组。每组10只。标准饲料对照组：喂食含有14％酪蛋白饲料；大豆蛋白饲料组：喂食含有14％大豆分离蛋白饲料；混合饲料1组：喂食含有7％酪蛋白加7％大豆分离蛋白饲料；混合饲料2组：喂食含有7％酪蛋白加14％大豆分离蛋白饲料。实验期用腺嘌呤灌胃共21d，建立肾损害大鼠模型，各组大鼠喂养相应饲料6周，测饲料消耗量、24h尿蛋白、尿钙、钙表观吸收率、储留钙量。[结果]4组实验大鼠饲料摄入量1d～30d无统计学差异，大豆蛋白饲料组和混合饲料1组实验结束时与另外两组相比，尿钙排泄量低，钙表观吸收率和储留钙量高，差异有统计学意义（P〈0．05）。[结论]蛋白质含量水平在14％条件下，含大豆蛋白的两种饲料对肾损害大鼠钙吸收、钙排泄的影响无统计学差异，有利于促进钙吸收，减少钙排泄。     

枢星联合方案预防顺铂(DDP)致恶心呕吐的观察及护理

目的:研究枢星联合方案(枢星联合地塞米松及胃复安)预防顺铂联合化疗所致恶心呕吐的疗效及护理干预。方法:将93例接受以顺铂为主联合化疗的患者随机分为两组,实验组53例接受70周期化疗并给予护理干预;对照组40例接受57周期常规化疗,观察1~5d,对两组恶心、呕吐控制率进行比较。结果:实验组对急性恶心、呕吐控制率分别为90%及94.3%,均较对照组(77.2%和80.87%)明显提高(P<0.05)。结论:枢星联合方案结合护理干预可较好地预防顺铂所致的急性恶心、呕吐,使患者以更为舒适的状态接受化疗。     

炎性肠梗阻15例诊治体会

目的探讨炎性肠梗阻的诊断和治疗。方法分析15例炎性肠梗阻的临床特点和治疗。结果15例经保守治疗,其中1例因肠扭转缺血损伤严重,出现全身性炎症反应综合征致多脏器衰竭死亡外,其他病例均痊愈,平均治愈时间为12.6d。结论炎症性肠梗阻由无菌性炎症致广泛肠粘连引起,应用小剂量激素减缓炎症反应,抗生素防止肠道菌群易位,经内镜逆行置入肠减压管及营养支持治疗,多数病例可保守治愈。     

Locomotor strategies before independent walking: prospective study of 50 mentally retarded children.

To investigate the association between pre-walking locomotor strategies and psychomotor developments in children with mental retardation (MR), 50 children with non-specific MR were included in this study. There were 29 boys and 21 girls, 96% of whom had moderate to severe MR. They were followed from 4-53 months to 25-99 months of age, and their follow-up periods ranged from 10 to 48 months (mean 30 months). According to the pre-walking locomotor strategies, these children were categorized into three groups: the crawling group (n = 34) who used crawling or creeping as their main locomotion pattern before independent walking; the shuffling group (n = 9) who used shuffling prior to independent walking; and the direct-walking group (n = 7) who did not have any other locomotor strategies except rolling. In almost all motor developmental milestones, children in the direct-walking group developed earlier than those in the crawling and shuffling groups. Children in the crawling group had more advanced developments than those in the shuffling group. The difference in the mean ratio developmental quotients of the Bayley Mental Scale among the three groups was not significant. The present study showed that crawling may not be a necessary prerequisite for early ambulation or better cognitive function in MR children.
