Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective:To investigate the predictive value of color Doppler ultrasound combined with electrocardio-gram for right heart dys function in patients with pulmonary heart disease(PHD).Methods:A total of 100 PHD patients admitted in Dongcheng Branch of First Affiliated Hospital of Anhui Medical University between January 2020 and December 2023 were retrospectively analyzed.According to results of 6min walking test(6MWT),pa-tients were divided into good right heart function group(n=64,≥350m)and right heart dysfunction group(n=36,＜350m).The indexes of cardiac color ultrasound[isovolumic relaxation time(IVRT),isovolumetric contraction time(IVCT)and right ventricular Tei index],ECG[24h mean R-R interval standard deviation(SDNN),normal R-R interval standard deviation per 5min(SDANN)and the ratio of low frequency components to high frequency components(LF/HF)]were compared between two groups.Receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of color Doppler ultrasound,ECG and their combination for right heart dys-function in PHD patients.Spearman correlation coefficient was used to analyze the association of color Doppler ul-trasound,ECG and their combination with right heart dysfunction in PHD patients.Results:Compared with those in good right heart function group,patients in right heart dysfunction group had significant higher IVRT[(120.64±14.08)ms vs.(97.87±10.93)ms],IVCT[(84.28±12.33)ms vs.(71.92±10.61)ms]and Tei index[(0.85±0.11)vs.(0.63±0.07)](P＜0.001 all),and significant lower SDNN[(75.52±12.58)ms vs.(85.58±11.75)ms],SDANN[(63.86±10.92)ms vs.(76.75±11.71)ms]and LF/HF[(1.33±0.19)vs.(1.84±0.27)](P＜0.001 all).ROC curve indicated that the AUC of color Doppler ultrasound combined ECG in diagnosing right heart dysfunction in PHD patients was 0.911(95％CI 0.838～0.959),which was significantly higher than those of color Doppler ultrasound[0.775(95％CI 0.681～0.853),Z=2.404,P=0.016]and ECG[0.688(95％CI 0.588～0.777),Z=3.968,P=0.001]alone.Spearman correlation analysis indicated that there was a significant positive correlation of color Doppler ultrasound(r=0.547),ECG(r=0.375)and their combination(r=0.810)with right heart dysfunction in PHD patients(P＜0.001 all),and the correlation between combined detection and right heart dysfunction in PHD patients was significantly higher.Conclusion:Color Doppler ultrasound combined with ECG possesses high diagnostic performance for right heart dysfunction in PHD patients.

Objective To investigate the expression levels and diagnostic value of long noncoding RNA(LncRNA)GUSBP3 and LncRNA SAM4 in peripheral blood of Kazakh type 2 diabetes mellitus(T2DM)patients in Xinjiang.Methods From January to September 2019,Kazakh T2DM patients in The First Affiliated Hospital of Shihezi University were recruited through outpatient or inpatient department(T2DM group,n=30).And 30 healthy people were selected as normal control(NC)group during the same period.The general data,biochemical indicators and differentially expressed LncRNA levels were compared between the two groups.Spearman correlation analysis was used to analyze the correlation between the target genes and each index.Logistic regression was used to analyze the influencing factors for T2DM.Receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of target genes.Results The differentially expressed LncRNA were LncRNA GUSBP3 and LncRNA SAM4 in the two groups.DBP,FPG,HbA1c,fructosamine,FIns,islet β cell function index,serum creatinine(Scr),LncRNA GUSBP3 and LncRNA SAM4 were higher in the T2DM group than in the NC group(P<0.05).Spearman correlation analysis showed that the expression of LncRNA GUSBP3 was positively correlated with Scr and serum uric acid(SUA)(r=0.328,0.322,P<0.05),and negatively correlated with FIns(r=-0.295,P<0.05).The expression of LncRNA SAM4 was positively correlated with SUA(r=0.275,P<0.05)and negatively correlated with LDL-C(r=-0.212,P<0.05).Logistic regression analysis showed that DBP(OR 1.175,95%CI 1.011～1.367),FIns(OR 0.852,95%CI 0.739～0.982),LncRNA GUSBP3(OR 0.378,95%CI 0.149～0.958)was influencing factors for T2DM in Kazakh population.The area under the ROC curve of LncRNA GUSBP3 was 0.789 for T2DM diagnosis.Conclusions The expression levels of LncRNA GUSBP3 and LncRNA SAM4 were higher in Kazakh patients with T2DM than in healthy people,and their expression levels are related to some biochemical indicators.DBP,FIns and LncRNA GUSBP3 are the influencing factors for T2DM in Kazakh population.LncRNA GUSBP3 may be a biomarker for the diagnosis of T2DM in Kazakh in Xinjiang.

Objective:To systematically analyze the incidence and influencing factors of frailty in elderly patients with hematologic malignancies.Methods:Research on frailty in elderly patients with hematologic malignancies was retrieved from Chinese and English databases such as China National Knowledge Infrastructure, Wanfang Data, PubMed, and Web of Science. The search period was from database establishment to August 23, 2024. Two researchers screened the included studies, conducted quality assessment, and extracted data.
