目的:探讨肝豆灵(GDL)对肝豆状核变性(WD)脂代谢异常的临床疗效及肝脂肪变性预测模型与WD脂代谢相关指标的相关性。方法:选取86例WD脂代谢异常患者,统计治疗前患者24 h尿铜、丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、血清甘油三酯(TG)、总胆固醇(TC)、载脂蛋白B(ApoB)、低密度脂蛋白胆固醇(LDL-C)、胆汁酸(BA)、γ-谷氨酰转移酶(GGT)、肝脂肪变性预测模型[肝脂肪变性指数(HSI)、浙江大学指数(ZJU指数)]、超声衰减系数成像(ATT)及中医证候积分,采用Pearson相关性检验分析探讨TG、TC、LDL-C、ApoB、ALT、AST、ALT/AST、BA、GGT、中医证候积分及ATT与HSI及ZJU指数的相关性。采用随机数字表法将患者分为观察组和对照组,每组各43例,观察组给予肝豆灵联合二巯丙磺钠(DMPS)治疗,对照组仅给予DMPS作为对照。经6个疗程的治疗后,观察比较治疗前后两组患者24 h尿铜、TC、TG、LDL-C、ApoB、HSI、ZJU指数、ATT、中医证候积分及临床有效率,并分析HSI、ZJU指数与血清TC、TG、LDL-C、ApoB、ALT、AST、ALT/AST、BA、GGT水平及中医证候积分、ATT的相关性。结果:Pearson相关性分析显示,WD脂代谢异常患者血清TC(r=0.811)、TG(r=0.826)、LDL-C(r=0.802)、ApoB(r=0.820)、ALT(r=0.497)、ALT/AST(r=0.826)、中医证候积分(r=0.716)、ATT(r=0.736)与HSI呈正相关(P<0.01),AST、BA、GGT与HSI无明显相关性。TC(r=0.718)、TG(r=0.765)、LDL-C(r=0.667)、ApoB(r=0.699)、ALT/AST(r=0.403)、中医证候积分(r=0.666)、ATT(r=0.684)与ZJU指数呈正相关(P<0.01),ALT、AST、BA、GGT与ZJU指数无明显相关性。观察组总有效率为86.05%(37/43),对照组总有效率为72.09%(31/43),观察组总有效率高于对照组(Z=-2.301,P<0.05)。与本组治疗前比较,两组患者24 h尿铜显著增加,TC、TG、LDL-C、ApoB水平显著下降,HSI、ZJU指数、ATT显著下降(P<0.01)。与对照组治疗后比较,观察组患者上述指标改善更优(P<0.05,P<0.01)。结论:肝豆灵能够有效改善WD患者铜、脂代谢水平,临床安全性较高,具有较好的临床应用价值,肝脂肪变性预测模型可有效地反映WD脂代谢异常程度。

目的观察加味栀子豉汤联合西药治疗新型冠状病毒感染后失眠的效果。方法选取2022年10月至2023年6月就诊于安徽中医药大学第一附属医院脑病中心的60例新型冠状病毒感染后失眠患者为研究对象,按照随机数字表法将其分为对照组和治疗组,各30例。对照组睡前口服右佐匹克隆3 mg,治疗组在对照组基础上加用加味栀子豉汤,疗程为2周。比较两组的治疗效果、睡眠质量、失眠严重程度及治疗安全性。结果停药时、停药2周后,治疗组的治疗总有效率略高于对照组,但差异无统计学意义(P>0.05)。治疗前,两组的匹兹堡睡眠质量指数(PSQI)、失眠严重指数量表(ISI)评分比较,差异无统计学意义(P>0.05);停药2周时,两组的PSQI、ISI评分低于治疗前,且治疗组低于对照组,差异具有统计学意义(P0.05)。两组治疗期间均有患者偶尔出现头晕或头痛症状,治疗组治疗期间有1例患者出现腹泻症状;两组的肝、肾功能随访时复查无明显异常。结论加味栀子豉汤联合西药治疗新型冠状病毒感染后失眠的有效性和安全性良好,值得临床推广。
