Aim The study was aimed to investigate the effect of Huangqi decoction (HD) on diabetic nephropathy.Methods Male diabetic db/db mice which develop diabetic nephropathy spontanously and nodiabetic db/m control mice were used in the current study, and they received the treatment of HD for 14 consecutive weeks.Results HD treatment dosedependently decreased the body weight, urine volume, water intake, food intake in the db/db mice, improved glucose tolerance and insulin resistance, lowered blood glucose, systolic blood pressure, serum glycosylated hemoglobin, insulin and insulin resistance index.The db/db mice also showed low levels of serum and urine creatinine, blood urea nitrogen and urine protein, and improved renal functions such as glomerular filtration rate and ATP production after HD treatment.Histological examination by PAS staining showed that HD treatment prevented the deterioration of basement membrane of glomerular capillary, mesangial matrix and renal tubular lumen in the db/db mice.Examining the cell signaling pathways which might be involved the pathology of diabetes, we found that HD upregulated the expressions of phosphoIR, phosphoIRS1307, phosphoPI3K and GLUT4,and downregulated the expression of phosphoIRS1636, phosphoAKT308, phosphoAKT473 and GLUT1 in a dosedependent manner.Conclusion Our study suggests that HD regulates the IRS1PI3KGLUT signaling pathway and significantly improves diabetic nephropathy.

肺隔离症(PS)是肺的先天畸形,特点为肺部有无功能的肺组织,由体循环供血,最常发生于左下肺后基底段,多见于儿童或青少年,因感染导致的反复发作性咳嗽和发热为其常见的临床表现.影像学检查在肺隔离症的诊断中起着非常重要的作用,平片对该病的发现有重要的意义;MSCT血管成像结合三维重建是评估隔离肺、显示隔离肺组织的供血和引流血管的最佳选择;DSA为明确诊断PS的金标准,也是术前或介入治疗前较好的检查.对于
纵隔畸胎瘤绝大多数位于前纵隔中上部,罕见于其它纵隔部位。囊性畸胎瘤CT表现为囊状水样密度块影边缘光滑,囊壁完整,囊壁厚度一般在2~5mm之间,并不是很厚,囊壁的一部分甚至可以很薄而不能满意地观察到,但囊壁的大部分可以清晰显示;囊内密度均匀,CT值接近于水,其内也可见少量脂肪、钙化、骨骼或牙齿等多种组织成分;病变与周围组织间脂肪间隙存在;增强扫描时,囊壁可呈轻至中度强化,囊内容物不强化。称其为显壁囊
韦格纳肉芽肿又称坏死性肉芽肿血管炎是,主要累及全身小动脉、静脉及毛细血管,上、下呼吸道及肾脏最常受累,发病率男性高于女性。WG床表现复杂多样,缺乏特异性,患者就诊科室不同,极易漏诊误诊。该患者出现上呼吸道、肺部损害,PET/CT检查明确诊断韦格纳肉芽肿,本例发病初期误诊为耳鼻喉科疾病,上呼吸道症状主要体现在咽痛、咳嗽,痰中带血丝并伴有伴牙齿疼痛,鼻部不适,听力下降,由于临床上对该病认识不足,也是导

目的:对盐酸地尔硫(革)片溶出度测定波长的选择进行改进.方法:采用最大吸收波长法测定盐酸地尔硫(革)片溶出度.结果:在《中华人民共和国药典》2010年版二部规定的波长240nm处测定.与该法在236nm最大吸收波长处测定结果一致.结论:建议将《中华人民共和国药典》2010年版二部测定盐酸地尔硫(革)片最大吸收波长改为236nm.
