ABSTRACT

Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.

ABSTRACT

Objective:To evaluate the value of the ratio of tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP) in evaluating right ventricular function of patients with hypertrophic cardiomyopathy (HCM) and heart failure with preserved ejection fraction (HFpEF).Methods:A total of 74 patients with HCM and HFpEF and 22 healthy individuals who visited the First Affiliated Hospital of Zhengzhou University from January 2021 to January 2023 were included in this study. The HCM patients with HFpEF were divided into three groups based on the tertiles of the TAPSE/PASP (low group: <0.280 0 mm/mmHg; middle group: 0.280 0-0.476 2 mm/mmHg; high group: >0.476 2 mm/mmHg). Conventional echocardiographic parameters were collected, and two-dimensional speckle tracking technology was used to obtain right ventricular strain parameters. The differences in parameters among the groups were compared, and the correlations between TAPSE/PASP and clinical parameters and right ventricular function parameters were analyzed.Results:The results of difference analysis showed that there were significant differences in 6-minute walking test, New York Heart Association grade (NYHA grade), incidence of atrial fibrillation, left atrial area (LAA), left ventricular global longitudinal strain (LVGLS), TAPSE, PASP, right ventricular fractional area change (RVFAC), right ventricular global longitudinal strain (RVGLS), right ventricular free wall strain (RVFWST) and cardiac magnetic resonance right ventricular ejection fraction (CMR-RVEF) among the three groups. The results of correlation analysis and multiple linear regression analysis showed that the TAPSE/PASP was positively correlated with 6-minute walking distance, RVFAC, tricuspid annulus peak systolic velocity (RV s′), and CMR-RVEF ( r=0.449, 0.284, 0.358, 0.577; all P<0.05). It was negatively correlated with N-terminal pro-brain natriuretic peptide (NT-proBNP), NYHA grade, LAA, mitral early diastolic peak velocity / mitral annulus early diastolic peak velocity (LV E/e′), LVGLS, RVGLS, RVFWST and tricuspid early diastolic peak velocity / tricuspid annulus early diastolic peak velocity (RV E/e′) (r/ rs=-0.336, -0.349, -0.468, -0.452, -0.444, -0.339, -0.405, -0.320; all P<0.05). The LAA and CMR-RVEF correlated independently with TAPSE/PASP(all P<0.05). Conclusions:The TAPSE/PASP can provide an early, simple, rapid, and convenient evaluation of right ventricular function in patients with HCM and HFpEF, so as to guide clinical treatment and monitoring disease progression.

ABSTRACT

Lung cancer is the malignant tumor with the highest morbidity and mortality worldwide, most lung cancer patients were diagnosed at an advanced stage. Using low-dose computed tomography(CT) for lung cancer screening in high-risk patients were proved to decrease lung cancer mortality and find out more early-stage patients. However, CT is of high false-positive rate which requires long-term follow-up or invasive examination to confirm the diagnosis. Serum tumor markers have become the focus of early diagnosis of lung cancer due to their characteristics of minimally invasive and good stability. Lung cancer-related antigens can be captured by the immune system to produce autoantibodies. These autoantibodies can appear in the early stage of lung cancer development with high concentration and stably exist. Therefore, the detection of serum autoantibodies can be effective in the early screening and early diagnosis of lung cancer. Here, we provide a systematic review of the production and detection methods of tumor autoantibodies and their application in the diagnosis and screening of malignant tumors, especially lung cancer.

ABSTRACT

Purpose@#Intrahepatic cholangiocarcinoma (ICC) is one of the most common liver primary tumors but its treatments are limited. Bioinformatics showed that the expression level of long non-coding RNA cancer-associated susceptibility 15 gene (CASC15) is correlated with ICC progression, but its functional mechanism remains unclear. @*Materials and Methods@#Tissues from ICC patients, tumor and adjacent tissue, were used for detection of the expression of CASC15. Clinical data were also collected for clinicopathologic and survival analysis. Short interfering RNA and lentiviral short hairpin RNA were used to knock down CASC15 and PRDX2 expression in ICC cell lines, for the analysis of changes of cell function and xenografts. RNA-pulldown and RNA immunoprecipitation assays were used to detect RNA-binding protein, PRDX2. Male nude mice were used for ICC xenografts, and livers were collected after 4 weeks for immunohistochemistry. @*Results@#CASC15 is highly expressed in ICC tissues and is related to higher TNM stage. Knockdown of CASC15 in ICC cells reduced cell proliferation, migration, invasiveness and increased apoptosis, and G1/S block. PRDX2 bound to CASC15. Knockdown of CASC15 decreased PRDX2 expression which was rescued by the inhibition of proteasome formation. Downregulation of PRDX2 resulted in G1/S block, reduced ICC cell invasion. Downregulation of CASC15 inhibited phosphoinositide 3-kinase (PI3K)/AKT/c-Myc pathway through downregulating of PRDX2 and overexpressed PRDX2 rescued the block. CASC15 knockout in ICC xenografts suppressed tumor development in vivo, decreased the expression of PRDX2 and Ki67 and inhibited PI3K/AKT pathway. @*Conclusion@#CASC15 promotes ICC possibly by targeting PRDX2 via the PI3K/AKT pathway, indicating poor prognosis and high degree of malignancy of ICC.

ABSTRACT

Lung cancer is the most common cancer and the leading cause of cancer death in the world, among which non-small cell lung cancer (NSCLC) accounts for about 85% of the total lung cancer. With the widespread of computed tomography (CT) and other imaging screening methods, the pathological types of lung cancer have changed from central squamous cell carcinoma to the early-stage lung adenocarcinoma, which is manifested as isolated pulmonary nodules and ground glass nodules on CT. Early diagnosis and treatment of lung cancer is of crucial clinical significance, and the continuous development and improvement of minimally invasive interventional techniques provide more options for lung cancer treatment, such as stereotactic radiation, percutaneous ablation, and bronchial intervention. This paper will make a review on the principle, advantages, disadvantages and prospects of minimally invasive interventional therapy commonly used in clinical practice.

ABSTRACT

Objective:To explore the feasibility and advantages of different MRI sequences in delineating target volumes in lung cancer with obstructive pneumonia or atelectasis (OC).Methods:Fourteen patients with OC underwent CT localization and MRI scan. CT, T 1WI, fat suppression T 2WI, LAVA, LAVA+ C images were collected respectively. CT and MRI images were fused in the treatment planning system, and GTV-p was target delineated on CT and MRI respectively. Results:CT showed tumor and OC boundaries in 2 patients, fat suppression T 2WI showed tumor and OC boundaries in 10 patients, LAVA showed tumor and OC boundaries in 12 patients, and LAVA+ C showed tumor and OC boundaries in 10 patients. Fat suppression T 2WI, LAVA, and LAVA+ C sequences showed similar resolving ability ( P>0.05). The GTV of T 2WI, LAVA, and LAVA+ C sequences decreased significantly compared with ST-GTV ( P<0.05), and T 2WI_GTV and LAVA_GTV were similar ( P>0.05). The GTV value of LAVA+ C was the smallest among all sequences. Conclusions:The application of MRI fat compression T 2WI, LAVA, and LAVA+ C sequences to the radiotherapy target volume delineation in lung cancer patients with OC improved the accuracy, among which the boundary resolution of LAVA was better than that of fat compression T 2WI, and LAVA+ C showed the best effect on tiny blood vessels.
