目的:观察Hp阳性消化性溃疡患者血清壳多糖酶3样蛋白1(chitosanase 3-like protein 1,CHI3L1)水平的变化,分析其临床意义。方法:选择本院消化内科2020年2月—2023年2月期间收治的136例消化性溃疡患者为研究对象,其中Hp阳性87例(Hp阳性组...目的:观察Hp阳性消化性溃疡患者血清壳多糖酶3样蛋白1(chitosanase 3-like protein 1,CHI3L1)水平的变化,分析其临床意义。方法:选择本院消化内科2020年2月—2023年2月期间收治的136例消化性溃疡患者为研究对象,其中Hp阳性87例(Hp阳性组)、Hp阴性49例(Hp阴性组),并将Hp阳性组分为Hp感染Ⅰ型(59例)、Hp感染Ⅱ型(28例)。比较Hp阳性组、Hp阴性组的年龄、性别、病情程度、吸烟史、饮酒史、饮食习惯、血清CHI3L1、转化生长因子-β1(transforming growth factor-β1,TGF-β1)、胃蛋白酶原(pepsinogen,PG)Ⅰ、PGⅡ等资料,并比较Hp阳性组不同病变部位、Hp感染类型、病情分期患者血清CHI3L1水平。分析消化性溃疡Hp感染的相关因素及血清CHI3L1水平对消化性溃疡Hp感染的诊断价值。结果:Hp阳性组血清CHI3L1、TGF-β1、PGⅠ、PGⅡ水平均高于Hp阴性组(P<0.01);Hp感染Ⅰ型患者血清CHI3L1水平高于Hp感染Ⅱ型患者(P<0.01);复合溃疡患者血清CHI3L1水平高于胃溃疡和十二指肠溃疡患者(P<0.01);活动期患者血清CHI3L1水平高于愈合期和瘢痕期(P<0.01),愈合期高于瘢痕期(P<0.01)。多因素logistic回归分析发现血清CHI3L1、TGF-β1、PGⅠ、PGⅡ水平均为消化性溃疡患者合并Hp感染的独立危险因素;ROC曲线分析显示,CHI3L1诊断消化性溃疡患者Hp感染的最佳截断值为96.22 ng/mL,灵敏度、特异度分别为79.82%、86.11%,曲线下面积为0.902。结论:Hp阳性消化性溃疡患者血清CHI3L1水平升高,CHI3L1是消化性溃疡Hp感染的独立危险因素,与Hp感染类型、溃疡部位和疾病严重程度密切相关,在消化性溃疡Hp感染诊断中具有较高的临床价值。展开更多
目的:探究腹腔镜辅助远端胃癌D2根治术治疗进展期胃癌对血清胃蛋白酶原(pepsinogen,PG)、胃泌素-17(gastrin-17,G-17)、低氧诱导因子-1α(hypoxia-inducible factor-1α,HIF-1α)及结肠癌转移相关基因1(metastasis-associated in colon ...目的:探究腹腔镜辅助远端胃癌D2根治术治疗进展期胃癌对血清胃蛋白酶原(pepsinogen,PG)、胃泌素-17(gastrin-17,G-17)、低氧诱导因子-1α(hypoxia-inducible factor-1α,HIF-1α)及结肠癌转移相关基因1(metastasis-associated in colon cancer-1,MACC1)水平的影响。方法:选取2017年10月至2021年11月在中部战区总医院进行远端胃癌D2根治术治疗的患者110例进行临床及随访研究,根据治疗方法的不同分为腹腔镜组及开腹组,每组55例。比较2组患者围手术期情况,血清PG、G-17、HIF-1α及MACC1水平,以及生存情况差异。结果:腹腔镜组切口长度、术中出血量、排气时间、进食时间、首次下床时间、住院时间均明显低于开腹组,差异有统计学意义(P<0.05)。术后7 d,腹腔镜组患者血清PGⅠ水平明显高于开腹组(P<0.05),G-17、HIF-1α及MACC1水平低于开腹组(P<0.05)。术后早期,腹腔镜组患者的并发症总发生率低于开腹组(5.45%vs.20.00%)(P<0.05)。腹腔镜组术后1、2、3年的生存率分别为90.91%、80.00%、78.18%,开腹组术后1、2、3年的生存率分别为87.27%、74.55%、70.91%,死亡率均无统计学意义(P>0.05)。log-rank检验腹腔镜组及开腹组治疗的患者生存状态比较差异无统计学意义(P>0.05)。结论:腹腔镜辅助远端胃癌D2根治术治疗进展期胃癌的效果及安全性较好,可促进患者术后早期康复,改善患者PG、G-17、HIF-1α及MACC1水平。展开更多
