DPP-4 has widespread organ distribution throughout the body and exerts pleiotropic effects via its peptidase activity. A representative target peptide is glucagon-like peptide-1, and inactivation of glucagon-like peptide-1 results in the development of glucose intolerance/diabetes mellitus and hepatic steatosis. In addition to its peptidase activity, DPP-4 is known to be associated with immune stimulation, binding to and degradation of extracellular matrix, resistance to anti-cancer agents, and lipid accumulation. The liver expresses DPP-4 to a high degree, and recent accumulating data suggest that DPP-4 is involved in the development of various chronic liver diseases such as hepatitis C virus infection, non-alcoholic fatty liver disease, and hepatocellular carcinoma. Furthermore, DPP-4 occurs in hepatic stem cells and plays a crucial role in hepatic regeneration. In this review, we described the tissue distribution and various biological effects of DPP-4. Then, we discussed the impact of DPP-4 in chronic liver disease and the possible therapeutic effects of a DPP-4 inhibitor.展开更多
目的观察胰岛素泵强化治疗后阿格列汀对初诊2型糖尿病(T2DM)患者的效果及对白细胞介素-6(IL-6)的影响。方法T2DM患者80例,随机分为试验组、对照组,每组40例。对照组患者应用二甲双胍联合阿卡波糖降糖治疗,试验组患者应用阿格列汀联合阿...目的观察胰岛素泵强化治疗后阿格列汀对初诊2型糖尿病(T2DM)患者的效果及对白细胞介素-6(IL-6)的影响。方法T2DM患者80例,随机分为试验组、对照组,每组40例。对照组患者应用二甲双胍联合阿卡波糖降糖治疗,试验组患者应用阿格列汀联合阿卡波糖降糖治疗,观察12周。结果(1)治疗后,两组患者空腹血糖(FBG)、餐后2 h血糖(2 h PG)、糖化血红蛋白(HbA1c)水平均较治疗前明显下降(P<0.05),且试验组较对照组下降更明显(P<0.05);两组空腹及餐后2 h C肽水平较治疗前升高(P<0.05),但两组之间差异无统计学意义(P>0.05)。(2)治疗后试验组不良反应明显少于对照组,治疗依从性明显优于对照组,差异均有统计学意义(P<0.05)。(3)治疗后两组IL-6水平均下降,试验组下降更明显(P<0.05)。结论对于初诊的T2DM患者,短期胰岛素泵强化治疗后应用阿格列汀能够较好控制血糖,不良反应少,患者依从性好,同时阿格列汀可以降低炎症介质IL-6水平。展开更多
目的探讨阿格列汀与吡格列酮联合治疗2型糖尿病的疗效及对胰岛β细胞功能改善的影响。方法选取T2DM患者79例,采用随机数字表法分为安慰剂(PBO)组(n=26)、阿格列汀组(ALO)组(n=26)和阿格列汀/吡格列酮(ALO/PIO)组(n=27)。16周后,对比3组...目的探讨阿格列汀与吡格列酮联合治疗2型糖尿病的疗效及对胰岛β细胞功能改善的影响。方法选取T2DM患者79例,采用随机数字表法分为安慰剂(PBO)组(n=26)、阿格列汀组(ALO)组(n=26)和阿格列汀/吡格列酮(ALO/PIO)组(n=27)。16周后,对比3组指标变化及临床疗效。结果 3组患者服药16周后,FPG、2 h PG、HbAlc、HOMAIR、HOMA-β指数比较,差异有统计学意义(P<0.05)。结论联合应用ALO/PIO治疗可以改善血糖控制,减轻胰岛素抵抗,改善胰岛β细胞功能。展开更多
