慢性丙型肝炎患者α干扰素和α干扰素受体1的检测

目的建立检测外周血单个核细胞α干扰素受体1(IFNAR1)及检测诱导表达α干扰素(IFN-α)的方法,评价慢性丙型肝炎患者外周血单个核细胞(PBMC)细胞免疫功能与α干扰素治疗的关系。方法Poly IC体外刺激正常对照组和慢性丙型肝炎病毒(HCV)感染组患者PBMC,利用病毒保护试验研究干扰素治疗前后患者PBMC表达的干扰素抗病毒生物学活性差异;IFN-α治疗前后,RT-PCR检测慢性丙型肝炎患者不同干扰素应答组患者PBMC IFNAR1表达的变化。结果对照组PBMC分泌的干扰素活性显著高于慢性丙型肝炎患者应答组患者(P<0.001);干扰素应答组患者PBMC分泌的干扰素活性随治疗时间延长而增加,治疗1个月后显著高于无应答组患者PBMC分泌的干扰素活性(P<0.01),后者始终处于低下水平;IFN-α治疗期间干扰素应答组患者PBMC IFNAR1水平从治疗前的高表达而逐渐减少,正常对照和干扰素无应答组患者PBMC IFNAR1的表达始终较低。结论慢性HCV感染患者的细胞免疫功能受损,不能正常表达IFN-α,但应答组患者经干扰素治疗后IFN-α表达能力逐渐恢复;干扰素无应答组患者PBMC IFNAR1表达受到严重抑制;慢性丙型肝炎患者PBMCIFN-α活性检测及IFNAR1检测结果也许可以作为干扰素治疗预后的判断指标。     

IgA肾病不是一个均一的疾病：知难行亦难

20世纪60年代免疫荧光技术在组织病理学中的应用,让我们认识到一组以肾小球IgA沉积为其免疫病理特点的肾小球疾病,并将他们命名为"IgA肾病".40年后的今天,长期临床观察的积累,大量基础研究的汇总,又让我们开始重新审视这一疾病的性质.IgA肾病不是一个均一的疾病这一概念正在为大家所接受,然而,如何将目前对IgA肾病发病机制研究中的发现与不同的临床表型联系起来进行整合深化,再据此提出针对性治疗措施,并在临床上加以验证,是目前IgA肾病研究中的一个突出问题.     

静息心率与老年慢性心力衰竭预后的相关性分析

目的探讨老年慢性心力衰竭（CHF）患者入院时静息心率与其心功能及预后的相关性。方法选择213例老年CHF患者，按入院时静息心率（治疗前心率）分为3组：CHF 1组（静息心率48～79次／min），CHF 2组（静息心率80～99次／min），CHF3组（静息心率100～140次／min）。并在循证医学标准治疗的基础上，对其入院、出院时及随访的心功能及预后进行分析。结果老年CHF患者入院时的静息心率与出院时的疗效（相关系数-0．163；P=0．017）、随访疗效（相关系数-0．161；P=0．019）显著负相关；与总死亡率（相关系数0．162；P=0．018）显著正相关。亚组分析显示：CHF1组、2组、3组间总有效率分别为92．7％、77．5％、73．2％；1组与2、3组间比较差异有统计学意义（P=0．011；P=0．007）。总死亡率分别为7．3％、22．5％、26.8％；1组与2、3组间比较差异有统计学意义（P=0．017；P=0．009），2、3组间比较差异无统计学意义。结论静息心率可作为判断老年CHF治疗效果和预后的预测指标之一。     

广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.
