肝移植术后血清降钙素原监测的临床意义

Objective To investigate the changes of procalcitonin (PCT) in patients after liver transplantation and explore their significance for diagnosis and differential diagnosis among bacterial infection, viral infection and acute rejection.Methods PCT was measured in serum of 25 liver trans-plant patients by immunofluorescence sandwich method and the patients were divided into the non-complication group, viral infection group, acute rejection group and bacterial infection group.Results The concentrations of PCT in the 1st, 2nd and 3rd day after transplantation were(24.50 ± 4.6)ng/ml, (21.40± 3.3)ng/ml and (12.25 ± 3.1)ng/ml, respectively and they presented a decreasing tendency.The concentrations of PCT in non-complication group, viral infection group and acute rejection group decreased gradually and were near the normal level of (0.51±0.11) ng/ml after 7～10 days.Moreo-ver, the concentrations of PCT in viral infection group and acute rejection group were (0.44 ± 0.16)ng/ml and(0.53±0.14)ng/ml when the patients were in fever.The concentration of PCT in the viral infection group were(15.70±5.1)ng/ml, which was significantly higher than that in other 3 groups (P<0.05) in the early days of fever.The statistical differences among the other three groups were not significant (P>0.05).Conclusion The concentration of PCT in serum is high in the 1st, 2nd and 3rd day then decreased gradually soon.The concentration of PCT is not high in viral infection or acute rejection while significantly high in bacterial infection, so it can be used to differentiate the bacterial infection from acute rejection and virus infection after liver transplantation.

抗反流药物联合持续气道正压通气治疗阻塞性睡眠呼吸暂停综合征伴咽喉反流的疗效分析CSCD

目的探讨抗反流药物联合持续气道正压通气(CPAP)治疗阻塞性睡眠呼吸暂停综合征(OSAS)伴咽喉反流(LPR)的疗效。方法收集2020年5月~2022年5月于南京医科大学附属苏州医院和江苏大学附属人民医院耳鼻咽喉科就诊的81例男性中重度OSAS伴LPR的患者,分别予以药物(药物组)、CPAP(CPAP组)及药物+CPAP(药物+CPAP组)治疗14 d,三组均于治疗前后行多导睡眠监测(PSG),填写咽喉反流症状指数(RSI)量表和Epworth嗜睡量表(ESS)。结果三种治疗方法均可改善OSAS伴LPR的症状,其中药物+CPAP组的总有效率高于药物组和CPAP组(P<0.05)。药物组治疗14 d后RSI评分较治疗前降低,差异有统计学意义(P<0.05),ESS评分、呼吸暂停低通气指数(AHI)、最低血氧饱和度(LSaO2)较治疗前无明显改善,差异无统计学意义(P>0.05);CPAP组治疗后RSI评分无明显改善,差异无统计学意义(P>0.05),ESS评分和AHI较治疗前下降,LSaO2较治疗前提高,差异有统计学意义(P均<0.05);药物+CPAP组治疗14 d后RSI评分、ESS评分、AHI均较治疗前降低,LSaO2较治疗前提高,差异有统计学意义(P均<0.05)。结论临床上对于OSAS伴LPR患者,使用抗反流药物联合CPAP治疗能更快速控制患者症状,且治疗效果更加快速有效。

3R疗法联合多奈哌齐对阿尔茨海默病患者认知功能的影响

目的探讨3R疗法联合多奈哌齐对阿尔茨海默病(AD)患者认知功能的影响。方法选取24例AD患者分为观察组和对照组,每组12例。观察组患者给予多奈哌齐常规治疗和3R疗法认知功能训练;对照组患者仅给予多奈哌齐常规治疗。治疗前、治疗24周后使用简易精神状态检查(MMSE)量表、日常生活活动(ADL)量表、AD评定量表认知部分(ADAS-Cog)对2组患者进行神经心理学指标评定并观察事件相关电位P300潜伏期和波幅的变化。结果治疗前2组患者MMSE、ADL、ADAS-Cog量表评分、P300潜伏期和波幅比较差异均无统计学意义(P>0.05)。治疗后2组患者ADL、ADAS-Cog量表评分与治疗前比较均有所降低(P<0.05),P300潜伏期均缩短(P<0.05),波幅均增加(P<0.05)。治疗后观察组患者ADL、ADAS-Cog评分、P300潜伏期均显著低于对照组(P<0.01),P300波幅高于对照组(P<0.05)。结论 3R疗法联合多奈哌齐可以有效延缓AD患者认知功能的减退,改善患者的生活质量。     

在教学中贯穿轻型胆源性胰腺炎的治疗新理念

目的探讨加速康复理念在轻症胆源性胰腺炎治疗中的效果、安全性及在教学中的应用。方法随机将60例急性轻症胆源性胰腺炎患者分为加速康复（ER）组与常规恢复（TE）组。ER治疗策略主要包括：早期手术、把握ERCP的绝对指证及早期肠内营养。比较两组的并发症发生率、再住院率、住院时间及住院费用。结果ER组平均住院时间和住院费用明显低于TR组：5．9天vs．10．6天（P〈0．01）;平均住院费用￥10,023vs．￥15,035（P〈0．01）。两组再住院率及并发症发生率无差异。结论加速康复理论可以安全有效的应用于轻症胆源性胰腺炎的治疗。早期手术、遵循ERCP的绝对指证及早期肠内营养策略的实施能够在不增加手术并发症及再住院率的情况下,明显减少住院时间及住院费用。在临床教学中应该注意上述理论的诠释及应用。
