全自动凝血检测仪在慢性阻塞性肺病患者急性加重期血液生化指标检测中的应用

慢性阻塞性肺疾病（chronic obstructive pulmonary diseases,COPD）是一类十分常见的临床慢性炎症相关性的呼吸系统疾病，且严重威胁老年人的身体健康。为了探究全自动凝血检测仪在COPD患者急性加重期血液中生化指标检测中的应用。本研究收集2019年12月至2020年12月于我院呼吸内科病房确诊为COPD急性加重期（n=83）及稳定期（n=25）的患者为研究对象，以同期正常体检的健康人群为对照（n=25）。分析各组患者上述指标水平之间的差异。结果显示，用于患者血浆各指标检测后，相较于健康对照组，急性加重COPD组及稳定期COPD组D-二聚体（D-D）、纤维蛋白原（FIB）水平显著升高（P<0.05），活化部分凝血活酶时间、凝血酶原时间及凝血酶时间显著减少（P<0.05）。其中COPD急性加重期患者各生化指标变化更为明显。D-D、FIB水平升高为COPD患者急性加重的独立危险因素（P<0.05）。ACL-TOP型全自动凝血检测仪的检测结果基本符合实验室诊断学的标准，可用于临床指标的检测。而D-D、FIB水平能够用于评估COPD特别是急性加重...

Effects of four multi-compound freezing medium on the quality of red drum (Sciaenops ocellatus) during frozen storage

Taking air freezing (AF) as the reference, the effects of four types of multi-compound freezing medium for cryogenic liquid quick-freezing (immersion freezing, IF) on the freezing rate, quality and myofibrillar protein (MP) denaturation of red drum (Sciaenops ocellatus) fillets during frozen storage (−18°C) from days 0 to 90 were studied. Samples were gathered on days 0, 15, 30, 45, 60 and 90 for analysis. The results showed that IF groups (IF-1: 20% ethanol, 30% propylene glycol, 10% sodium chloride aqueous solution; IF-2: 20% ethanol, 20% propylene glycol, 10% glycerol, 10% sodium chloride aqueous solution; IF-3: 20% ethanol, 20% propylene glycol, 10% polyethylene glycol, 10% sodium chloride aqueous solution; IF-4: 20% ethanol, 20% propylene glycol, 5% glycerol, 5% polyethylene glycol, 10% sodium chloride aqueous solution) significantly shortened the time to cross the formation zone of maximum ice crystals while the freezing rate was 6.13 times higher than the AF group after adding 30% propylene glycol as the freezing medium. Furthermore, compared with the AF group, the IF groups significantly reduced losses in the water-holding capacity, the myofibrillar fragmentation index, microstructure damage, texture characteristics, drip loss and water migration (P < 0.05). In addition, the MP of IF groups had higher maximum transition temperatures (T_max1 and T_max2), total sulfhydryl content, Ca²⁺-ATPase activity and relative α-helix content compared with the AF group. In conclusion, IF could significantly increase the freezing rate of red drum fillets, and slow down quality deterioration and denaturation of MP during frozen storage for 90 days (−18°C). In particular, IF-2 (20% ethanol, 20% propylene glycol, 10% glycerol, 10% sodium chloride aqueous solution) was found to be more suitable for the immersion freezing of marine fish among the four multi-compound freezing medium.
