髓源性抑制细胞(MDSC)是骨髓和脾脏中的骨髓生成途径产生的一组具有高度免疫抑制活性的不成熟异质性骨髓细胞,与机体自身免疫性疾病、细菌感染、病毒感染等疾病密切相关。MDSC的主要功能为通过抑制T细胞活化、促进Treg的增殖以及与巨噬细胞相互作用而减弱或抑制机体的免疫反应。中医认为阴阳失调是导致疾病的主要原因,因而中医药治疗疾病是以借助中药的偏性帮助机体维持阴阳平衡为目的和手段。免疫系统及其功能的阴阳平衡与免疫功能及其病理变化密切相关。近年来,研究发现多种中药及其活性成分能够调控MDSC的表达参与机体免疫调控来治疗肿瘤等多种疾病。本文就近年来中医药调控MDSC的相关研究进展做一综述。  相似文献

Objective To evaluate the clinical application of automated urine formed elements analyzer and/or urine dipstick analyzer for examination of urinary formed elements in screening urinary tract infection (UTI). Methods 148 fresh midstream clear-catch urine samples from the UTI patients and 284 fresh midstream clear-catch urine samples from non-UTI subjects were selected. Bacteria culture was performed for bacterial colony counting and identification. Bacteria counts ( BACT), yeast-like fungus and WBC were performed by UF-looOi automated urine formed elements analyzer. Leukocyte esterase test (LEU) and nitrite test (NIT) were performed by URISYS 2400 urine dipstick analyzer. We evaluated data obtained from urine dipstick analyzer, UF-1000i and combination of UF-1000i with urine dipstick analyzer and the results was compared with those obtained from quantitative bacterial culture. Then we evaluated the sensibility, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy. Results Among the 148 patients with UTI, the positive rate of the quantitative bacterial culture was 73.6% (109/148), the positive rate of LEU and NIT detected by dipstick test 26. 4% (39/148).There was significantly statistical difference between bacterial culture and strip test(χ2 = 55.68 ,P < 0. 05 ). The positive rate of urine flow cytometry by UF-1000i with either positive of BACT and WBC was 91.2%(135/148), which was higher than the positive rate of the quantitative bacterial culture. There was significant difference between two methods (χ2 = 14. 70, P < 0. 05 ). The positive rate of anyone positive among BACT, WBC, LEU and NIT was 94. 6% (140/148) when detected with combination of dipstick test and UF-1000i, which was higher than the positive rate of the quantitative bacterial culture. And there was significant difference between two methods (χ2 = 20. 45, P < 0. 05 ). The sensitivity of dipstick test was low (26. 4% ,39/148 ), and specificity was high ( 99. 3%, 282/284 ) . The sensitivity, specificity, positive predictive value, negative predictive value of BACT detected by UF-1000i in diagnosing urinary tract infection were 92. 6% ( 137/148 ), 39. 8% ( 113/284 ). 44. 5% ( 137/308 ) and 91.1% ( 113/124 ), respectively. If the dipstick test was combined with UF-1000i, the sensitivity, negative predictive value, specificity, positive predictive value and accuracy were 98.0% ( 145/148 ), 97.1% ( 100/103 ). 35.2% (100/284) ,44. 1% (145/329) and 56. 7% (245/432), respectively. Conclusions The combination of urine dipstick test and automated urine formed elements analyzer UF-1000i plays an important role in early diagnosis of UTI. And it has significant value in diagnosis of UTI, especially for the patients with negative bacterial cultures of urine sample.  相似文献

目的 评价凝血酶原时间(PT)作为判断肝病患者细胞损伤程度实验指标的两种报告方式。方法 选择肝病患者104例,其中肝炎肝硬化37例,慢性肝炎32例,肝癌36例,急性肝炎35例。30例口服华法林病人做对照组。采用ISI值不同的2种凝血活酶试剂进行PT测定。结果 急性黄疸性肝炎患者,二种凝血活酶试剂测定的INR结果有显著性差异;慢性活动性肝炎、肝硬化、肝癌患者,二种凝血活酶试剂测定的国际标准化比值(INR)结果无明显差异。急性黄疸性肝炎、肝癌患者,二种凝血活酶试剂测定的活动度(PTA)结果有显著性差异。结论 目前尚不能否定INR可作为肝病病情估计时的门标准化报告方式;PT并不是评价肝病病情的最佳指标;PTA仍为目前门作为肝病病情估计时的首选报告方式。  相似文献

肺炎克雷伯菌是医院内感染最常见的细菌之一,也是血流感染和泌尿道感染的第二大致病菌。近年来,肺炎克雷伯菌耐药菌株的出现已成为抗感染界关注的焦点。目前,耐药肺炎克雷伯菌的治疗主要是联合用药,但联合用药存在不良反应大、成本高、更易产生耐药性等问题。随着中医中药的治疗作用被逐渐重视,中药作为替代疗法或中西药结合抗感染已进入研究者的视线,因此,用以评价药物疗效的动物模型引起广泛关注。该文就肺炎克雷伯菌动物感染模型及在中药抗感染应用中的研究进展作以下综述。  相似文献
