六安市健康成人4项凝血指标正常值范围的建立

目的: 通过测定六安市健康成年人群的凝血酶原时间(PT)、活化部分凝血酶时间(APTT)、纤维蛋白原(FIB)、凝血酶时间(TT),建立六安市实验室血浆凝血指标的正常值范围.方法: 使用法国STA-compact全自动血凝仪,采用凝固法对300名健康成年人进行PT、APTT、FIB和TT测定.结果: 初步建立六安市健康成人4项凝血指标正常值范围,PT 11.06～14.24 s;APTT 27.57～42.23 s;FIB 1.91～3.99 g/L;TT 14.05～18.47 s.结论: 指标正常值范围对疾病的预防、诊断、疗效及预后均有重要的指导意义,各实验室应制定适合的指标正常值范围.     

降钙素原在细菌感染中临床应用的研究

目的：探究细菌感染中应用降钙素原的方法与临床效果。方法：选取我院2016年2月~2016年7月期间收治的102例细菌感染病例，分为实验组（细菌、病毒感染）与对照组，实验组52例，对照组50例，对比两组患者行PCT检测，观察检测水平。结果：实验组检测阳性率高于对照组，差异具有统计学意义，（P＜0.05），实验组中细菌感染患者与病毒感染患者PCT水平差异具有统计学意义，重度感染者PCT比轻度感染者高（P＜0.05）。结论：应用降钙素原检测细菌感染，作用明显，诊断率高，值得临床应用推广。     

CA153、CEA与细针吸取细胞学联合检测在乳腺癌诊断中的价值

目的:探讨血清糖类抗原（CA）153、癌胚抗原（CEA）和细针吸取细胞学（FNAC）联合检测在乳腺癌诊断中的价值。方法:选取67例乳腺癌病人和32例乳腺良性疾病病人,分别做血清CA153、CEA和FNAC检测,分析3项指标联合检测对乳腺癌的诊断价值。结果:CA153 检测的敏感性为8.96%,特异性为100.00%,准确性为38.38%;CEA敏感性16.42%,特异性96.88%,准确性为43.43%;FNAC的敏感性为83.58%,特异性为100.00%,准确性为88.89%;3项联检敏感性提高到88.06%,准确性提高到90.91%,特异性也达到了96.88%。FNAC、CA153、CEA单项检测诊断乳腺癌的曲线下面积（AUC）分别为0.910、0.709和0.705,3项联合诊断的AUC（0.942）高于单项指标AUC。结论:CA153、CEA和FNAC联合检测可以提高乳腺癌诊断的灵敏度和准确性,对乳腺癌的早期诊断有着较高的参考价值。

Low-temperature Plasma Promotes Fibroblast Proliferation in Wound Healing by ROS-activated NF-κB Signaling Pathway

Low-temperature plasma (LTP) has shown great promise in wound healing, although the underlying mechanism remains poorly understood. In the present study, an argon atmospheric pressure plasma jet was employed to treat L929 murine fibroblasts cultured in vitro and skin wounds in BALB/c mice. The in vitro analysis revealed that treatment of fibroblasts with LTP for 15 s resulted in a significant increase in cell proliferation, secretion of epidermal growth factor (EGF) and transforming growth factor-βi (TGF-βi), production of intracellular reactive oxygen species (ROS), and the percentage of cells in S phase, protein expression of phosphorylated p65 (P-p65) and cyclinD1, but a noted decrease in the protein expression of inhibitor kappa B (IκB). The in vitro experiments demonstrated that 30-s LTP treatment enhanced the number of fibroblasts and the ability of collagen synthesis, while 50-s treatment led to the opposite outcomes. These results suggested that LTP treatment promotes the fibroblast proliferation in wound healing by inducing the generation of ROS, upregulating the expression of P-p65, downregulating the expression of IκB, and activating the NF-κB signaling pathway and consequently altering cell cycle progression (increased DNA synthesis in S phage).
