腹膜透析和血液透析患者贫血程度及血清EPO水平的比较

为探讨腹膜透析和血液透析对慢性肾衰患者贫血的影响及其发生机制。检测了１０例腹爱和１６例血透患者的血清促红细胞生成素（ＥＰＯ）血红蛋白及其相关指标。结果显示血红蛋白腹透组较血透组明显高，血清ＥＰＯ腹爱组高因透组。表明在贫血方面腹透优于血透、其原因可能与腹透能更好地清除中分子物质，促进ＥＰＯ产生有关。     

腐植酸钠干预食管上皮重度增生初探

<正> 食管上皮细胞重度增生(简称重增)是一种癌前病变。在早期食管癌脱落细胞中,多有增生背景。这说明,重增与食管癌的发生有密切关系。在高发区,不仅食管癌高发而且重增也高发。因此,探索有效阻断癌前病变方法巳引起了研究者的重视。我们试用腐植酸钠干预治疗重增患者,初步获得了逆转重增的效果。对象和方法一九八二年在高发区涉县,经食管脱落细胞学检查,确诊68例重增患者。在治疗后,除迁居、外出和死于其它病者外,共复查53例,其中男性     

系统性红斑狼疮患者外周血CD4+CXCR5+滤泡辅助性T细胞样细胞的变化及糖皮质激素对其的影响

Objective To investigate the frequencies of CD4+CXCR5+T cells in the CD4+T cells of peripheral blood of patients with systemic lupus erythematosus (SLE) and the effect of glucocorticoid on it.Methods Frequencies of CD4+CXCR5+T cell were analyzed by flow cytometry in 45 active,20 inactive SLE patients and 20 healthy controls.Differences between groups and the effect of glucocorticoid were analyzed.Meanwhile, the expression of CXCR5 on CDI9+B cells was analyzed. Independent sample t test was used for statistical analysis between twogroups, ANOVA was applied for data analysis between 3 groups,,nonparameterical Spearman's analysis was used for correlation analysis and repeated measurement ANOVA were used to compare the parameters before and after treatment. Results The percentage of CD4+CXCR5+ in CD4+T cells was increased in patients with SLE compared with healthy controls[(16±7)% vs (12±3)%, P＜0.01].It was increased in patients with active SLE [(18±7)%] compared with healthy controls (P＜0.05) but there was no significant difference between inactive SLE[(11±4)%] and healthy controls(P＞0.05). The percentage in patients with LN was higher than that in patients without LN, but without significant difference[(18±7)%vs (14±7)%, P=0.05 ]. The percentage of CD4+CXCR5+T cells was positively correlated with SLEDAI,the titer of ANA and level of ESR but negatively correlated with the level of C3 (P<0.05 for each).No correlation was found between duration and the levels of CRP and immunoglobulin.. The percentage in patients with high anti-dsDNA group was also higher than that of the low group, but no differences were found between anti-Sm antibody positive and negative groups neither between anti-SSA/SSB antibody positive and negative groups(P＞0.05 for each).The expression level of CXCR5 on CD19+B cells in active SLE patients was lower than that of healthy controls[(85±11)% vs (94±3)%, P＜0.05 ]. The percentages of CD4+CXCR5+T cells in 10 untreated active SLE patients were decreased at day 1,day 3 and day 7 after being treated with dexamethasone (20mg/d) when compared with those before the treatment (P＜0.05 for each), but the percentages of CD19+CXCR5+B cells had no significant change (P＞0.05 for each).Conclusion These results demonstrate that the abnormality of CD4+CXCR5+T cells may play an important role in the pathogenesis of SLE.     

铁皮石斛试管苗生长发育动态研究

目的对铁皮石斛试管苗进行生长发育规律研究,为试管苗各生长发育时期合理调控技术措施的确定提供科学依据。方法采用常规方法,测定不同生长时期试管苗的生长指标、多糖和蛋白质含量及光合特性指标。结果播种后5~8个月时铁皮石斛试管苗的苗高和茎粗增长最快,6、11个月时各有1次分蘖高峰,5、9、12个月时各有1次发根高峰;7~8个月、10~12个月时试管苗生物量积累速率最高。铁皮石斛试管苗根与茎叶之比(R/T)相对较小,平均单株茎叶干重占总干重的90.6%。11个月时试管苗的多糖含量最高(5.07%),以后开始下降;8个月时试管苗可溶性蛋白质含量最高(211.28 mg/g),以后逐渐减少,以12个月时的含量最低(119.55 mg/g)。6~11个月时的试管苗生长代谢旺盛。从干物质积累动态、多糖及蛋白质含量变化、试管苗活力和生产成本等方面综合考虑,10个月左右的铁皮石斛试管苗出瓶移栽较为合适。生长发育过程中,试管苗的叶绿素含量变化幅度较大,呈减小→增加→再减小的趋势,光合速率与叶绿素含量的变化趋势基本一致。10个月之后试管苗的叶绿素开始降解。试管苗光饱和点和最大电子传递速率的变化相对稳定,9、10个月时的电子传递速率最高,为26μmol/(m2.s),而12个月时的光饱和点和电子传递速率最低。结论铁皮石斛种子萌发率及试管苗质量受种子成熟度的影响较大;组培室光照强度为27μmol/(m2.s),光强不足可能是试管苗生长发育的主要限制因子之一;播种后生长10个月左右的铁皮石斛试管苗出瓶移栽较为合适;通过调节红蓝光的光质配比来调节叶绿素a/b的比值,将有利于促进试管苗的生长发育。
