NT-proBNP与BMP-7水平在糖尿病肾病中的诊断价值

目的探讨血浆氨基末端脑钠肽前体(NT-proBNP)及骨形态发生蛋白7(BMP-7)在糖尿病肾病(DN)中的应用价值及其与肾功能的关系。方法选取2013年6月至2014年6月湖北医药学院附属东风医院内分泌科收治的DN患者52例作为DN组,根据尿蛋白排泄率分为尿蛋白正常组(18例)、微量尿蛋白组(20例)和临床尿蛋白组(14例),另选取50例健康体检者为对照组。采用酶联免疫吸附测定试验法、电化学检测法测量52例DN患者及50例健康对照组血浆中BMP-7、NT-proBNP水平,并检查患者肌酐、血清尿素氮及估算的肾小球滤过率(e GFR)水平。结果 DN组患者血浆NT-proBNP水平显著高于对照组(P<0.05),而BMP-7水平低于对照组(P<0.05)。随着DN患者病情损害程度的增加,NT-proBNP水平显著上升,而BMP-7水平显著下降(P<0.05)。NT-proBNP与肌酐、血清尿素氮呈正相关(P<0.05),而与e GFR呈负相关(P<0.05)。BMP-7与肌酐、血清尿素氮呈负相关(P<0.05),而与e GFR呈正相关(P<0.05)。以病理活检为金标准,与单一指标检测相比,联合检测的敏感性、准确性、特异性较高。结论 DN患者存在明显的肾功能损害,NT-proBNP与BMP-7与肾功能具有密切的关系,通过测定NT-proBNP、BMP-7水平能有效预测DN患者肾功能损伤程度。两者联合检测可提高诊断的敏感性及特异性。     

膝骨性关节炎与C反应蛋白和血沉的相关性

目的分析膝骨性关节炎(KOA)与C反应蛋白(CRP)和血沉(ESR)的相关性。方法选取2018年1月～2018年9月在我院治疗的KOA患者80例,将病情处于缓解期的38例患者临床资料分为对照组,将病情处于活动期的42例临床资料分为观察组。观察对比两组ESR、CRP水平,并分析KOA活动程度与ESR、CRP的相关性。结果观察组ESR、CRP水平显著高于对照组,差异有统计学意义(P0.05);经Pearson相关性检验结果显示,KOA疾病活动程度与CRP、ESR呈正相关(P0.05)。结论 KOA活动程度与ESR、CRP间具有相关性,通过测定ESR、CRP水平对患者病情严重程度进行评估,指导临床开展治疗。     

儿童呼吸道感染患者血清IP-10，MCP-1 平检测的临床意义

目的 研究皖南地区儿童呼吸道病原体感染的流行病学特点,探讨混合病原体感染患儿血清中干扰素诱生蛋白10(interferon-inducible protein-10,IP-10),单核细胞趋化蛋白-1( monogyte chemoattractant protein-1),MCP-1表达水平在急性呼吸道感染诊断中的应用价值。方法 收集2017年6月～2019年6月皖南医学院第一、二附属医院急性呼吸道感染患儿血标本,采用间接免疫荧光法检测呼吸道九项病原体IgM,分析不同年龄段呼吸道病原体感染的差异性。采用酶联免疫吸附试验检测混合感染患儿血清中IP-10,MCP-1的表达水平,分析炎症因子表达水平与疾病严重程度的相关性。结果 5 122例急性呼吸道感染患儿中,以肺炎支原体感染率最高,混合感染患儿共544例,以肺炎支原体联合呼吸道合胞病毒感染率最高。检测血清中的CRP,IP-10和MCP-1的表达水平相比较单独感染组,混合感染组升高更为明显,对比组之间的差异均具有统计学意义(F=1.045～4.889,均P<0.05)。相关性研究分析显示,混合感染组IP-10,MCP-1与CRP 表达水平呈正相关性(r = 0.612,P<0.001; r= 0.804,P<0.001)。结论 急性呼吸道感染患儿中,混合感染更易表现为咳嗽、鼻塞流涕及发热等症状,同时炎症反应增强,病情的严重程度增加,血清IP-10和MCP-1表达水平可作为急性呼吸道感染病情严重程度指标之一。     

脓毒症的诊断与治疗

近年来对于脓毒症及其并发症的认识和治疗研究有了很大进展,但严重的脓毒症、脓毒性休克的死亡率仍高达30%~50%,特别是真菌菌血症病死率高达50%。本文概述脓毒症的概念和诊断,着重从早期目标治疗、血管收缩药物的应用、抗生素的使用、控制感染源、肾上腺皮质激素的应用、机械通气策略、重组人活化蛋白C的应用、镇静剂和止痛剂及神经肌肉阻断剂的使用、脓毒症的辅助治疗和支持治疗等方面阐述脓毒症的治疗进展。希望能引起临床工作者对脓毒症的重视,提高脓毒症患者的生存率。     

卵巢子宫内膜异位囊肿粘连程度及相关因素分析

Objective To investigate the relationship between degree of endometrioma adhesions and clinical feature, surgical treatment and postoperative recurrence. Methods From Jan 2003 to Mar 2008, 662 patients with endometrioma undergoing laparoscopic ovarian endometrioma excision in Peking Union Medical College Hospital were studied retrospectively. All patients were classified into four groups according to the extent of adhesions: 31 cases in none adhesions group, 123 cases in mild adhesions group (filmy thickness, avascular, easily separated adhesions), 310 cases in moderate adhesions group (less than a half of ovary was adjacent to dense thickness adhesions which was difficult to separate, or above a half of ovary were adjacent to filmy thickness adhesions) and 198 cases in severe adhesions group (above a half of ovary was adjacent to dense thickness, well vascularized adhesions which was difficult to separate, and always involved the other pelvic organs, observed angiogenesis). The comparison of degree, characteristics, period of pain, lab test, surgical management and postoperative recurrence was performed among those above groups. In the mean time, risk factors and multinomial logistic regression were analyzed. Results (1)Clinical characteristics: The incidence of patients with dysmenorrhea, dyspareunia, straining feeling in anus, chronic pelvic pain and the level of CA125 (>35 kU/L) was remarkably higher in moderate-to-severe adhesion groups than in none-to-mild adhesions groups (P=0.000, 0.000, 0.001, 0.006 and 0.000, respectively). Infertility rate were significantly higher in severe adhesions group(15.7%,31/198) than none adhesions group(3.2%,1/31), mild adhesions group(11.4%,14/123) and moderate adhesions group(9.7%,30/310, OR=1.728, P<0.05).(2)Operating time and blood loss: Operating time of each groups was as followed: (37±15) min in none adhesions group, (42±19) min in mild adhesions group, (50±20) min in moderate adhesions group and (63±22) min in severe adhesion group. Blood loss was (23±12) ml in none adhesion group, (31±27) ml in mild adhesion group, (40±32) ml in moderate adhesion group and (70±67) ml in severe adhesions group. Thicker adhesions result in longer operation time and more blood loss. (3)Combined with other disease: The ratio of patients who combined with adenomyosis or deeply infiltrating endometriosis in moderate-to-severer adhesion groups was higher than patients in none-to-mild adhesions groups (OR=3.466, P=0.000). (4) Postoperative recurrence: It was categorized into recurrence of pain and cyst. Moderate-to-severe adhesions was related to higher recurrence rate of pain (OR=1.685,P=0.046), but was irrelevant to recurrence of cyst. Conclusion The more extent of endometrioma adhesions was related to severer pelvic pain symptoms, longer operating time and more blood loss. Postoperative pain recurrence rate was observed in moderate-to-severe adhesion group. Extent of adhesions was irrelevant to cyst recurrence.
