The purpose of this study is to investigate the significance of RUNX3/H3K27me3 co-expression in surgically resected non-small-cell lung cancer (NSCLC) patients. Using tissue microarray (TMA), immunohistochemistry, fluorescent double immunostaining, and western blotting, 208 NSCLC and 5 benign pulmonary patients were studied of their expression of runt-related transcription factor 3 (RUNX3), trimethylated histone H3 at lysine 27 (H3K27me3), enhancer of zeste homolog 2 (EZH2), and Ki-67. Apoptotic index in cancerous tissue was evaluated via TdT-mediated dUTP-biotin nick end labeling (TUNEL). The correlation between clinicopathologic parameters and overall survival was determined by Cox regression and Kaplan-Meier survival estimates and log-rank test. GEPIA and KM plotter were used for validation of some survival analyses. As a result, together with other regular prognostic factors, RUNX3/H3K27me3 co-expression was found to be closely correlated with better prognosis in either pTNM-I or POCT-naive NSCLC patients, which might partially result from a higher cancerous apoptotic index. In conclusion, RUNX3/H3K27me3 co-expression defined some specific NSCLC population with better prognosis and longer OS and could probably be used as a biomarker in the prediction of better postoperative outcomes.MutS homolog 2 (MSH2) is a crucial participant in human DNA repair, and lots of the studies functionally associated with it were begun with hereditary nonpolyposis colorectal cancer (HNPCC). MSH2 has also been reported to take part in the progresses of various tumors' formation. With the help of GTEx, CCLE, and TCGA pan-cancer databases, the analysis of MSH2 gene distribution in both tumor tissues and normal control tissues was carried out. Kaplan-Meyer survival plots and COX regression analysis were conducted for the assessment into the MSH2's impact on tumor patients' clinical prognosis. In an investigation to the association of MSH2 expression with immune infiltration level of various tumors and a similar study on tumor immune neoantigens, microsatellite instability was subsequently taken. It was found that high expression of MSH2 is prevalent in most cancers. MSH2's efficacy on clinical prognosis as well as immune infiltration in tumor patients revealed a fact that expression of MSH2 in prostate adenocarcinoma (PRAD), brain lower-grade glioma (LGG), breast-invasive carcinoma (BRCA), and head and neck squamous cell carcinoma (HNSC) posed a significant correlation with the immune cell infiltration level of patients. Likewise as above, MSH2's expression comes in a similar trend with tumor immune neoantigens and microsatellite instability. MSH2's expression in the majority of tumors is a direct factor to the activation of tumor-associated pathways as well as immune-associated pathways. MSH2's early screening or even therapeutic target role for sarcoma (SARC) diagnosis is contributing to the efficiency of early screening and overall survival in SARC patients.

To assess the efficacy and safety of nivolumab for advanced renal cell carcinoma (RCC) via meta-analysis.

In this systematic review and meta-analysis, we searched PubMed, Embase, Science Citation Index Expanded, The Cochrane Library, and Web of Science for randomized controlled trials (RCTs) using nivolumab for patients with advanced RCC published before 30 December 2021. Quality assessments and meta-analyses were performed on all the literature assessed for eligibility.

Of 203 studies identified as potentially eligible from 3214 studies in a preliminary search, three RCTs including 2550 RCC cases met the inclusion criteria and were of high quality. Meta-analysis showed benefits of nivolumab in the progression-free survival (PFS) (HR = 0.73, 95% CI 0.54 to 0.99,

=0.04) and overall survival (OS) (HR = 0.70, 95% CI 0.63 to 0.78,

< 0.001) of patients with advanced RCC, and no increase in documented adverse events was recorded.

Nivolumab plus ipilimumab has significant benefits versus sunitinib in the treatment of advanced RCC in terms of tumor progression control and prolongation of OS and PFS, with a manageable safety profile.

To assess the clinical efficiency of endoscopy-assisted laparoscopic versus laparoscopic surgery for gastrointestinal stromal tumors and the impact on patients' coagulation, surgical condition, and complications.

Between November 2016 and May 2020, 126 eligible patients diagnosed with gastrointestinal stromal tumor (GIST) in our institution were recruited. They were concurrently randomly assigned at a ratio of 1  1 to receive either laparoscopic gastrectomy (reference group) or endoscopy-assisted laparoscopic gastrectomy (research group). The two groups were compared in terms of patients' coagulation function, surgical conditions, and complications.

The two groups had similar preoperative coagulation indices and the postoperative levels of activated partial thromboplastin time (APTT) and thromboplastin time (TT) (

> 0.05). Compared with the reference group, the research group showed lower PT levels (10.48 ± 0.68 vs. 11.97 ± 0.46) and higher FIB levels (0.67 ± 0.11 vs. 0.29 ± 0.07) (

< 0.05). Cer prognosis and quality of life of patients with a good safety profile, so it is worthy of clinical application.

Renal cell carcinoma (RCC) affects the life quality of patients with advanced diseases despite good prognosis and exhibits abnormal lipid metabolism. Zinc oxide nanoparticles (ZONs) are metal oxide nanoparticles that are regarded as promising therapeutic candidate for multiple diseases. This study was for exploring the function of ZONs in RCC.

We established

cell model and

xenograft model to determine the antitumor effect of ZONs. Cell viability and proliferation were evaluated via the cell counting kit-8 (CCK-8), colony formation, and 5-ethynyl-2'-deoxyuridine (EDU) assay. Protein and RNA levels were checked by using immunohistochemistry (IHC) and qRT-PCR assay. ROS, malondialdehyde (MDA), triglyceride, and total cholesterol were quantified to assess lipid oxidation and synthesis. Oil red O staining was performed to check lipid droplets accumulation. The ACSL4 and miR-454-3p expression in tumor samples and normal tissues were evaluated. The luciferase reporter gene assay was performed for checking the interaction between miR-454-3p and ACSL4 3'UTR region.

ZONs suppressed the proliferation and viability of RCC cells both

and

. ZONs suppressed accumulation of ROS, MDA, triglyceride, total cholesterol, and lipid droplets in RCC cells, along with upregulated miR-454-3p. miR-454-3p targeted the 3'UTR region to suppress its expression. In patient samples, ACSL4 expression was notably elevated and indicated poor prognosis of RCC patients.

ZONs treatment notably impeded proliferation, lipid accumulation, and oxidation in RCC cells, through upregulating miR-454-3p to suppression the function of ACSL4. Our data suggested that ZONs are promising and effective agent for RCC treatment.

Human epidermal growth factor receptor 2 (HER2) is a member of the large ErbB family and an important oncogene in many solid tumors. Pyrotinib has been approved for the treatment of HER2-positive, recurrent, or metastatic breast cancer. However, there are very few clinical studies on pyrotinib in other HER2-positive solid tumors. Therefore, more evidence of clinical research is impendently needed to shepherd pyrotinib-based therapy in HER2-positive nonbreast advanced solid tumors.

. We performed a retrospective analysis of HER2-positive nonbreast advanced solid tumors patients with HER2 amplification or mutations who were administered with pyrotinib-based therapy in Henan Cancer Hospital between July 1, 2019, and December 2, 2021. In our research, 25 eligible patients were included with 16 patients with lung cancer, 6 patients with gastric cancer, 2 patients with colorectal cancer, and 1 patient with cholangiocarcinoma. Progression-free survival (PFS) is our main research end point.

The median PFS was 1.6%,

> 0.99). The most common treatment-related adverse events (TRAEs) were diarrhea (84%), but only 3 patients (12%) reported grade 3 diarrhea with good control.

These results show that in HER2-positive nonbreast advanced solid tumors, the treatment based on pyrotinib regimen has good antitumor activity and acceptable safety. This retrospective study aims to promote larger clinical studies to further clarify the efficacy and safety of pyrotinib in the treatment of nonbreast solid tumors.

The expression levels of LINC01087, miR-135a-5p, and PPM1E in thyroid carcinoma tissues were detected by QRT-PCR. Cell viability was detected using the CCK-8 method. Transwell assay was used to assess the ability of cells to invade. The targeting relationship between LINC01087 and miR-135a-5p was detected by dual luciferase reporting assay. In comparison with normal thyroid tissues and cells, the expression level of LINC01087 in thyroid cancer tissues and TPC-1 and K1 cells increased, and the expression level of miR-135a-5p in thyroid cancer tissues and TPC-1 and K1 cells decreased. LINC01087 knockdown and the high expression of miR-143-3p inhibited the proliferation, invasion, and EMT processes of TPC-1 and K1 in thyroid cancer cells. LINC01087 negatively targeted miR-135a-5p. Has-miR-135a-5p inhibited the malignant evolution and EMT of thyroid cancer by targeting PPM1E. The PPM1E overexpression can reverse the inhibitory effect of LINC01087 gene knockdown on the proliferation, migration, and invasion of thyroid cancer cells. LINC01087 can promote the proliferation and apoptosis of thyroid cancer cells, and its mechanism may be related to the miR-135a-5p/PPM1E axis.

To evaluate the diagnostic value of artificial intelligence-assisted CT imaging in benign and malignant pulmonary nodules.

The CT scan screening of pulmonary nodules from November 2018 to November 2020 was retrospectively collected. The diagnosis of pulmonary nodules and surgical treatment were performed. A total of 194 nodules in 152 patients with clear pathological results were observed. All patients underwent CT examination to analyze the consistency of the results of artificial intelligence, physician reading according to imaging features, multidisciplinary team work (MDT) diagnosis, and postoperative pathological results; the diagnostic efficacy of different diagnostic methods for solitary pulmonary nodules and the differences of ROC curve and AUC were analyzed. The accuracy, specificity, sensitivity, positive predictive value, negative predictive value, false negative rate, and false positive rate of different diagnostic methods for pulmonary nodules were calculated, and the ROC curves of different diagnostic methods were plotted.
