占永立教授从咽论治IgA肾病的理论与实践探析

本文从理论与临床实践2方面总结了占永立教授从咽论治IgA肾病的经验。占教授将Ig A肾病分为3型进行辨证论治:1)肺气不足,热毒扰咽证; 2)脾气虚弱,热邪客咽证; 3)肾阴亏虚,余热留咽证。治疗上以清热解毒利咽为主,兼以扶正,根据病情灵活选方用药,取得较好的临床疗效。

Steroid pulse therapy impaired endothelial function while increasing plasma high molecule adiponectin concentration in patients with IgA nephropathy.

BACKGROUND: Decreased plasma adiponectin is associated with impaired endothelial function and, thereby, increased risk for cardiovascular events. Glucocorticoid (GC) affects vascular endothelial cells either favourably or harmfully depending upon the dosages and duration. We examined the effect of GC pulse therapy on vascular endothelial function. METHODS: Fourteen young patients with IgA nephropathy were evaluated for flow-mediated vasodilation (FMD), plasma levels of adiponectin both in high molecular weight (HMW adiponectin) form and in single molecular form (total adiponectin), hepatocyte growth factor (HGF), asymmetric dimethylarginine (ADMA), and high-sensitive C-reactive protein, before and after a course of GC pulse therapy. RESULTS: GC pulse therapy significantly decreased FMD (from 7.2 +/- 2.6 to 5.7 +/- 2.5%, P < 0.01). Meanwhile, plasma adiponectin levels were significantly augmented (total adiponectin: from 10.2 +/- 4.0 to 12.1 +/- 6.3 microg/ml, P < 0.05; HMW: from 6.5 +/- 3.2 to 7.7 +/- 3.3 microg/ml, P < 0.05). In parallel, elevated concentrations of serum HGF (from 0.28 +/- 0.12 to 0.63 +/- 0.38 ng/ml, P < 0.01) and plasma ADMA (from 0.45 +/- 0.07 to 0.53 +/- 0.04 nmol/ml, P < 0.05) were observed. CONCLUSIONS: GC pulse therapy impaired endothelial function while increasing plasma adiponectin levels, which may in turn restore the endothelial function in patients with IgA nephropathy.     

伊贝沙坦与苯那普利、卡托普利对高血压肾病患者尿总蛋白排泄量及内生肌酐清除率影响的比较

目的 :观察伊贝沙坦 (irbesartan)和血管紧张素转换酶抑制剂对高血压肾病患者尿总蛋白排泄量 (UPER)与内生肌酐清除率 (Ccr)的影响 ,比较不同的血管紧张素拮抗剂上述作用的差别。方法 :以序贯试验的方法选择了用伊贝沙坦或苯那普利中卡托普利治疗的高血压肾病患者共 6 6例 ,分为人数相等的 3组 ,进行了治疗前、后 3组间降压效果、UPER、Ccr的比较。结果 :伊贝沙坦了压效果与苯那普利、卡托普利相似 ,但伊贝沙坦对UPER、Ccr的效果优于苯那普利和卡托普利 ,3组比较有统计学的差异 (P <0 .0 1)。伊贝沙坦组未见于干咳现象 ,而苯那普利组及卡托普利组分别干咳发生率分别为 4 .5 %和 13.6 %。结论 :肾功能轻、中度损害的高血压肾病患者服用伊贝沙坦 ,不仅可有效降低血压 ,还可以更好地降低UPER ,提高Ccr。     

激素间歇冲击及小剂量维持治疗IgA肾病的随机对照研究

目的:探讨激素间歇冲击及小剂量维持与血管紧张素转换酶抑制剂治疗中度蛋白尿IgA肾病的疗效及其影响因素。方法:47例IgA肾病患者随机分为实验组和对照组。对照组(21例)给予ACEI药物治疗,实验组(26例)在此基础上口服泼尼松0.5mg/kg,隔日给药,治疗12个月,并在治疗的第1、3、5个月初分别给予甲基泼尼松龙0.5g/d,冲击3d。对肾脏病理改变进行WHO分级并对各种病变进行半定量分析。结果:两组间在性别、年龄、临床及病理资料间无统计学差异。平均随访14个月后,实验组尿蛋白完全缓解8例(30.8%),部分缓解14例(53.8%),无缓解4例(15.4%);而对照组分别为4例(19.1%),3例(23.8%),12例(57.1%),有统计学差异(P<0.01)。治疗前后,实验组血肌酐分别为(89.9±30.3)μmol/L及(88.2±32.8)μmol/L;对照组分别为(89.5±37.9)μmol/L及(104.0±49.7)μmol/L,但两者比较均无统计学意义(P>0.05)。多因素分析显示疗效与肾小球硬化率及肾小管间质病变呈负相关。结论:激素间歇冲击及小剂量维持治疗能显著减少蛋白尿,维持肾功能稳定。影响疗效的主要因素为肾小球硬化率及肾小管间质病变程度。     

The shape of stress: the use of frequent sampling to measure temporal variation in S‐IgA levels during acute stress

Previous studies have indicated that statistically significant increases in Secretory immunoglobulin A (S‐IgA) can be achieved in as little as 5min as a result of mental stress. However, the temporal resolution of these changes is low and therefore the rate and pattern of changes during the stress task and during subsequent recovery is unclear. A within‐subjects design was used to examine levels of S‐IgA before, during and after a short (8 min) mental stress task. S‐IgA was measured from saliva samples obtained every 2 min during the entire 30‐min session. Significant increases in S‐IgA concentration were observed as early as the task instruction period, with additional increases during the stress task itself. The data also show a rapid recovery of S‐IgA, with a return to baseline levels within 6 min. Results suggest that S‐IgA changes can occur very rapidly and that the observed increases are short‐lived.
