阴茎硬结症是一种临床上较为少见的男性疾病,因其起病隐秘,病症复杂,病程缠绵且容易复发,同时伴阴茎疼痛、勃起障碍等症状,对男性正常的工作生活造成较大影响。现代医学对于阴茎硬结症尚无有效治疗手段,作者通过长期临床观察,认为阴茎硬结症属于中医络病范畴,以络病学说“易滞易瘀”的病理特点为基础,将“阳虚络瘀”视作阴茎硬结症的基本病机,运用“温阳通络”法治疗阴茎硬结症验案多例,疗效颇著。 相似文献

目的 探讨血脂水平与动脉瘤性蛛网膜下腔出血(aSAH)后迟发性脑缺血(DCI)的相关性。方法 回顾性分析2014年1月至2015年12月收治的74例aSAH的临床资料,采用多因素Logistic回归分析检验性别、年龄、动脉瘤位置、动脉瘤大小、世界神经外科医师联盟(WFNS)分级、改良Fisher分级、Hunt-Hess分级、治疗方式、总甘油三脂、总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、脂蛋白(a)、载脂蛋白A、载脂蛋白B等因素与DCI的关系。结果 74例中,65例入院后检测血脂,20例出现DCI,45例未出现DCI,aSAH后DCI的发生率为30.8%。多因素Logistic回归分析显示高甘油三酯及改良Fisher分级是aSAH后DCI发生的独立危险因素。结论 及时检测aSAH患者的血脂水平和对患者进行改良Fisher分级对DCI的诊断治疗均有参考价值。 相似文献

Objective To investigate the effects of diets with different calorie and nutritional values on pubertal onset in female rats. Method Female Wistar rat models receiving calorie-deprived (group R) (Experiment 1) ,fat-rich(group F) ,glucose-rich(group G) and protein-rich(group P) (Experiment 2) test diets were established,and rats receiving diets with normal caloric value were considered as control group (group C). The body weight (BW) ,food-intake and vaginal patency (VP) were observed. The rats were killed at the day of vaginal patency. The BW, uterus weight (UW), uterus index (UI), calorie intake per day (CI), perirenal fat weight (PFW) and perirenal fat index (PFI) were measured. The serum levels of leptin, ghrelin, IGF- Ⅰ were tested by means of ELISA.Results Experiment 1:The VP was retarded in group R compared with group C (P<0. 01). There was a significant difference in BW, UW,UI ,CI,leptin and ghrelin at the VP day between group R and group C (all P<0.01) ,and no significant difference in IGF- Ⅰ levels between these two groups. Experiment 2 :The VP was retarded in group F,group G and group P in comparison with group C (P<0.01). The BW, PFW and PFI in group G and group F were markedly higher than those in group P and group C. The leptin level in group F was the highest, and the lowest in group P. The ghrelin level in group G was the highest,and that in group P was the lowest. However,there were no significant differences in IGF- Ⅰ and UI among these, four groups. Conclusion The normal pubertal onset of female rats requires sufficient caloric stores and balanced nutrient. Diets malnutrition and fat-rich, glucoserich and protein-rich test diets all delay pubertal onset in female rats. 相似文献

宫内γ线照射对仔鼠脑发育影响的研究 总被引:2,自引:1,他引:1
目的:探讨宫内γ线照射对仔鼠脑发育的影响。方法:采用整体动物实验,于SD大鼠孕17天给予1.0Gyγ线照射,观察生后1,4,7,14及21日龄仔鼠脑重、脑DNA和蛋白质含量的动态变化。结果:照射组仔鼠生后1,4,7,14及21日龄脑重、脑/体比值及脑组织蛋白质含量,与对照组比较均显降低;对照组仔鼠出生后脑组织DNA含量逐天下降,至生后第4天后又逐渐增高,照射组仔鼠第1及21日龄脑组织DNA含量显低于对照组。结论:孕17天大鼠受1.0Gyγ线照射可影响仔鼠脑发育,表现为脑重、脑DNA和蛋白质含量的降低。 相似文献

缺氧诱导对人结肠癌SW480细胞增殖和缺氧诱导因子-1α、血红素氧合酶-1基因表达的影响 总被引:1,自引:0,他引:1
目的构建缺氧诱导模型和观察缺氧对人结肠癌SW480细胞系生长和缺氧诱导因子-1α(hypoxiainduciblefactor-1alpha,HIF-1α),血红素氧合酶-1(hemeoxygenase-1,HO-1)表达的影响。方法利用氯化钴(cobaltchloride,CoCl2)构建缺氧诱导模型,以MTT试验观察不同程度缺氧条件对SW480细胞生长曲线的影响;利用RT-PCR方法测定氯化钴缺氧诱导与SW480细胞HIF-1α和HO-1基因mRNA表达的时效和量效关系。结果适度缺氧(CoCl2浓度<200μmol/L)可刺激肿瘤细胞增殖,过度缺氧(CoCl2浓度>250μmol/L)则抑制其生长;HIF-1α、HO-1基因mRNA表达与氯化钴缺氧呈明显的量效关系和时效关系;HIF-1α与HO-1基因mRNA的表达在缺氧诱导量效关系(相关系数r=0.786,P<0.05)和时效关系(相关系数r=0.863,P<0.05)中均存在显著的正相关性。结论缺氧可以刺激SW480细胞增殖;HIF-1α和HO-1基因的表达与肿瘤缺氧程度密切相关;HO-1的适量表达对缺氧细胞具有细胞保护作用,其过度表达可能导致细胞损伤和凋亡。 相似文献
