目的探讨终末期肝病食谱应用程序(end-stage liver disease recipe application,ESLDR APP)对肝硬化患者并发营养不良及衰弱的治疗效果。方法选取2022年3月至2022年8月在内蒙古科技大学包头医学院第二附属医院住院的60例肝硬化并发营养不良及衰弱患者,通过ESLDR APP为上述患者提供3个周期的治疗(每30 d为1个治疗周期),于每个周期结束到院复查,以排除依从性较差的患者,并检查有无食物过敏或出现其他并发症。比较患者使用ESLDR APP治疗3个周期前后的BMI、上臂围(arm circumference,AC)、三头肌皮褶厚度(triceps skin-fold thickness,TSF)及上臂肌围(arm muscle circumference,AMC)的差异,总蛋白、白蛋白、胆碱酯酶及胆汁酸的差异,优势手握力的差异,衰弱表型评估(frailty phenotype,FP)结果的差异。并于3个治疗周期结束后通过调查问卷的形式收集上述患者对ESLDR APP的评价。结果最终共入组53例患者,男28例,女25例。患者使用ESLDR APP治疗3个周期前后BMI、AC、TSF、AMC、总蛋白、白蛋白及胆碱酯酶水平均显著升高,胆汁酸水平、FP结果显著降低,差异均有统计学意义(P均0.05);说明达到了一定程度的干预效果。通过调查问卷方式收集53例肝硬化患者对ESLDR APP的评价,37例(69.81%)认为本APP对改善营养不良及衰弱非常有效;10例(18.87%)认为一般有效;6例(11.32%)认为无效。结论ESLDR APP通过为患者制定科学营养的食谱,达到了改善肝硬化并发营养不良及衰弱的目的,提升了蛋白水平及营养状况,使患者受益。

背景:Interleukin(IL)-22 has been found to be up-regulated in the liver in patients with chronic hepatitis B and C virus infection.目的:The present study aims to identify the characteristics of IL-22 and its correlation with liver fibrosis in HBV-infected subjects.方法:Intrahepatic and peripheral IL-22-producing cells were comprehensively investigated in 50 patients with chronic hepatitis B(CHB) and 27 patients with liver cirrhosis, as well as 30 healthy *** impacts on liver fibrosis were analyzed in vitro assays.结果:IL-22 was mainly produced by CD4 T cells in peripheral blood, but its production shifted to innate immune cells in livers of enrolled *** particular, IL-22 was preferentially produced by intrahepatic NK and γδ T cells and IL-22+IL-17a+IFN-γ- Th17 cells in LC patients, compared with CHB patients and HC subjects, and was positively associated with liver fibrosis severity in CHB *** importantly, high levels of IL-22 R expression were identified on human *** vitro IL-22 exposure largely activated HSCs, as indicated by increased p STAT3 expression and fibrotic protein production, and also prevented soluble TRAILmediated HSC apoptosis through reducing caspase 3 activity and increasing bcl-2 *** examine the essential role of the cytokine, a T cell-mediated liver fibrosis model was established, and blockade of IL-22 in HBV-transgenic mice with liver fibrosis induced by activated T cells significantly reduced α-SMA expression and restricted liver fibrosis progression.结论:IL-22-producing cells were enriched in the livers, preferentially in the activated hepatic stellate cells and may prevent their apoptosis in situ in HBV-infected *** findings may facilitate the rational development of immunotherapeutic strategies targeting IL-22 for the blockade of liver fibrosis.

Herbal medicines have recently been recognized as the second most common cause of drug-induced liver injury （DILI） in the United States. However, reliable methods to identify the DILl causality of some herbs, such as Heshouwu （dried root ofPolygonum multiflorum）, remain lacking. In this study, a total of 12 307 inpatients with liver dysfunction and 147 literature-reported cases of Heshouwu DILI were screened. A general algorithm indicated that only 22.5% （9/40） and 30.6% （45/147） of all hospitalization and literature case reports, respectively, demonstrate the high probability of DILI causality of Heshouwu. By contrast, 95% （19/20） of all cases prospectively investigated by pharmacognosy, phytochemistry, and metabolomic tests exhibited highly probable causality, including a patient who was previously incorrectly attributed and a case that was excluded from Heshouwu causality by pharmacognostic evidence. Toxin （heavy metals, pesticides, and mycotoxins） contamination was also excluded from Heshouwu DILI causality. The objectivity of these screening methods for Heshouwu DILI diagnosis addresses safety concerns regarding stilbene-containing herbal medicines and dietary supplements.
