As well known there exist complex interaction between the trace elements, and the trace elements and other substances, so the trace element research must be involved to the com-prehensive effect of multifactors, other than single element. We determined the contents of fifteen trace elements in serum from thirty patients with liver cancer and thirty healthy adults by ICP-AES analysis. The obtained data were analysed statistically by not only routine statistical test bat also multi-variate discrimination analysis, multi-variate stepwise regression and non-linear mapping algorithm. It is hoped that it can provide some valuable informations for investigation on relationship betwecn trace elements and cancer.展开更多
目的了解癌症患者乙型肝炎病毒(hepatitis B virus,HBV)的感染状态和感染特点。方法回顾性分析2017年7月26日至2023年9月18日于广西医科大学附属肿瘤医院确诊的92031例癌症患者的HBV血清标志物检测结果,以肝癌、非肝癌进行分组,比较未感...目的了解癌症患者乙型肝炎病毒(hepatitis B virus,HBV)的感染状态和感染特点。方法回顾性分析2017年7月26日至2023年9月18日于广西医科大学附属肿瘤医院确诊的92031例癌症患者的HBV血清标志物检测结果,以肝癌、非肝癌进行分组,比较未感染(全阴或Anti-HBs阳性)、感染(除外Anti-HBs任何一项阳性)、隐性感染(occult hepatitis B virus infection,OBI;HBsAg阴性、血清或肝组织HBV DNA阳性)的占比。结果92031例癌症患者的HBV总感染率为73.75%(67876/92031),其中肝癌患者的HBV总感染率为97.65%(8922/9137),非肝癌患者的HBV总感染率为71.12%(58954/82894),肝癌组的普通感染率和OBI率均显著高于非肝癌组(均P<0.001)。肝癌组HBV血清标志物中HBsAg、HBeAg、Anti-HBe、Anti-HBc的阳性率明显高于非肝癌组(均P<0.001),但Anti-HBs的阳性率低于非肝癌组(P<0.001)。肝癌组和非肝癌组分别有20种和27种血清标志物组合模式,其中14种模式构成比在两组间差异有统计学意义(均P<0.001);两组均有7种OBI血清组合模式,其中5种模式构成比在两组间的差异有统计学意义(均P<0.05)。结论癌症患者HBV感染状态和血清学组合模式复杂,区分肝癌与非肝癌进行HBV感染统计更利于癌症患者的HBV感染评估。展开更多
目的观察原发性肝癌(primary hepatocellular carcinoma,PHC)与血清25(OH)维生素D水平的相关性。方法抽取2018年8月—2020年8月莆田市第一医院PHC患者50例作为观察组,抽取同时期健康体检者50例作为对照组。检测两组血清25(OH)D3水平以...目的观察原发性肝癌(primary hepatocellular carcinoma,PHC)与血清25(OH)维生素D水平的相关性。方法抽取2018年8月—2020年8月莆田市第一医院PHC患者50例作为观察组,抽取同时期健康体检者50例作为对照组。检测两组血清25(OH)D3水平以及甲胎蛋白(alpha fetoprotein,AFP)水平。结果观察组血清25(OH)D3水平低于对照组,差异有统计学意义(P<0.05)。观察组AFP水平高于对照组,差异有统计学意义(P<0.05)。PHC血清患者25(OH)D3水平与中国肝癌分期(China live cancer staging,CNLC)、淋巴结转移有关,差异有统计学意义(P<0.05)。结论针对PHC患者,其血清25(OH)D3水平主要相关因素为CNLC分期、淋巴结转移,根据血清25(OH)D3水平可为疾病治疗及其预后评估提供依据。展开更多

Their mean urinary and serum pseudouridine levels were 39.2=11.5 nmol / /μmol creatinine and 3.4 ± 1.3 μmol / L, 24.5 = 5.4 nmol / μmol creatinine and 2.5 = 0.5 μmol / L, 22.8 ± 7.8 nmol / μmol creatinine and 2.3 = 0.4 μmol / L, 26.4 ± 4.6 nmol / μmol creatinine and 2.3 = 0.4 μmol / L, respectively. Exceeding the mean plus 2SD of pseudouridine of healthy control was considered as positive value for the diagnosis of primary liver cancer. Thus the positivity of urinary and serum pseudouridine in hepatoma was 71.3% and 70.0%, respectively. The positive rate of combined pseudouridine and alpha-fetoprotein assay was 91.3% in patients with hepatoma. Besides, pseudouridine levels could elevate before positive localization and reduce to normal levels after tumor resection. The results showed that the determination of pseudouridine is of clinical significance in the diagnosis and monitoring of primary liver cancer.展开更多
