Numerous molecular epidemiology studies have been performed about the frequency of virulence genes in patients with infection so far. This study was conducted to detect transcriptional profile by cDNA of virulence genes in gastric biopsy samples of gastritis and gastric carcinoma patients.
In a case-control study, based on the prevalence of gastritis and gastric cancer in Sanandaj city during 2018 and 2019, 23 and 11 gastric antral biopsy samples with infection were collected from gastritis and gastric carcinoma patients by the consecutive and available sampling method. Pathological characters, including tumor grades and tumor areas for gastric carcinoma biopsy samples prepared from gastric cancer areas, were determined by the pathologist. Total RNA of gastric antral biopsy samples was extracted, and their cDNA was synthesized by TaKaRa kit. virulence genes' cDNA using specific primers and PCR was detected. This study's results were analyzed by SPSS version 25 and statics chi-square tests for determination of relationship and correlation between cDNAs of transcriptional profile and clinical outcomes infection, including gastritis, gastric carcinoma, tumor grades, and tumor area.
The positive statistical correlations were observed between transcripts of , , and genes and infection clinical outcomes ( < 0.05).
Detection of the virulence genes' cDNA in gastric biopsy samples can help provide the prognosis of clinical outcomes.
迄今为止,已经进行了许多关于感染患者中毒力基因频率的分子流行病学研究。本研究旨在通过胃炎和胃癌患者胃活检样本中毒力基因的cDNA检测转录谱。
在一项病例对照研究中,根据2018年和2019年Sanandaj市胃炎和胃癌的患病率,采用连续和可用抽样方法,从胃炎和胃癌患者中收集了23份和11份感染幽门螺杆菌的胃窦活检样本。由病理学家确定病理特征,包括从胃癌区域制备的胃癌活检样本的肿瘤分级和肿瘤面积。提取胃窦活检样本的总RNA,并使用TaKaRa试剂盒合成其cDNA。使用特异性引物和PCR检测毒力基因的cDNA。本研究结果采用SPSS 25版进行分析,并通过统计学卡方检验确定转录谱cDNA与幽门螺杆菌感染临床结局(包括胃炎、胃癌、肿瘤分级和肿瘤面积)之间的关系和相关性。
在幽门螺杆菌、空泡毒素A、细胞毒素相关基因A和尿素酶基因的转录本与幽门螺杆菌感染临床结局之间观察到正统计学相关性(P<0.05)。
检测胃活检样本中毒力基因的cDNA有助于提供临床结局的预后信息。
