RESUMO

With the gradual increase in the diagnosis rate of early gastric cancer, clinicians must consider prevention of gastric anatomical structure and physiological function while ensuring the radical treatment of the tumor. Pylorus-preserving gastrectomy is a function- preserving operation that preserves the pylorus, inferior pyloric vessel, and the vagus nerve in patients with early middle gastric cancer. One of the major controversies at present is the thoroughness of limited lymph node dissection for pyloric-preserving gastrectomy. Various studies have reported that the lymph node metastasis rate of early middle gastric cancer was low, especially in the suprapyloric region, inferior pylorus and the upper pancreatic region. Partial lymph node dissection is required for vascular and neurological protection, which is also safe and feasible in studies reported by major centers. Many clinical studies have been carried out in Japan and Korea, and postoperative follow-up has gradually increased evidence, providing the basis for the safety of lymph node dissection. In large case studies comparing pylorus- preserving gastrectomy with traditional distal gastrectomy, the incidence of postoperative morbidity, such as dumping syndrome, bile reflux esophagitis, weight loss, and malnutrition is low. Sentinel lymph node navigation technology is gradually applied to the diagnosis and treatment of early gastric cancer, and its clinical application value still needs further research.

RESUMO

ABSTRACT Background: Cervical cancer (CC), as a serious menace to the health of women, has long been one of the most lethal gynecologic neoplasms throughout the world. Long non-coding RNA (LncRNA) NR2F1-AS1 has been documented to exert crucial functions in many malignant tumors. Nonetheless, the function and molecular mechanism of NR2F1-AS1 in CC remain completely unknown. Objective: This study aimed to explore the function and molecular mechanism of NR2F1-AS1 in CC. Methods: The expression levels of NR2F1-AS1, miR-642a-3p, NR2F1 in CC tissues, and cell lines were examined by reverse transcription real-time quantitative polymerase chain reaction. Cell viability, proliferation, migration, and invasion were detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, colony formation and Transwell assays. The protein levels of epithelial-mesenchymal transition markers and NR2F1 in CC cells were assessed by Western blot analysis. The correlations among NR2F1-AS1, miR-642a-3p, and NR2F1 were estimated through luciferase reporter and RNA immunoprecipitation assays. Results: NR2F1-AS1 expression was clearly downregulated in CC tissues and cell lines. Molecular mechanistic experiments showed that NR2F1-AS1 overexpression upregulated NR2F1 expression in CC cells by directly binding to miR-642a-3p, and inhibiting by this way cell viability, proliferation, migration, and invasion in CC. Rescue assays showed that NR2F1 knockdown or miR-642a-3p overexpression offset NR2F1-AS1 upregulation-induced inhibition on CC cell malignant phenotypes. Conclusion: These findings revealed that NR2F1-AS1 played a tumor suppressor role in CC by mediating the miR-642a-3p/NR2F1 axis.

RESUMO

Purpose

To assess the occurrence and the associated risk factors for nocturia among middle-aged and elderly people from public health centers in southern Taiwan. Materials and Methods

Data were part of our previous cross-sectional study which used a self-administered questionnaire for the assessment of lower urinary tract symptoms. A total of 1011 responders who were at least 40 years of age were enrolled from any of four local public health centers for any reason in Pingtung County, Taiwan. Nocturia, as a dependent variable, was defined as two or more episodes per night. Covariables included age, gender, and chronic illnesses (obesity, hypertension, diabetes, cardiovascular disease, and stroke). Multivariate logistic regression was applied to determine the risk factors associated with nocturia. A p-value of less than 0.05 was considered statistically significant. Results

About 38.1% (385/1011) of the participants reported having nocturia ≥ 2 episodes/night, and the occurrence of nocturia increased with advanced age. More than half (51.2%, 197/385) participants with nocturia perceived at least “a bit of a problem” on the sleep quality. The multivariate logistical regression showed that the independent risk factors for nocturia were age (OR:1.06, CI:1.05-1.08), hypertension (OR:1.58, CI:1.16-2.16) and diabetes (OR:1.59, CI:1.03-2.45) and obesity (OR:1.47, CI:1.02-2.10), while a borderline effect on nocturia was produced by cardiovascular disease (OR:1.66, CI: 0.98-2.79) and stroke (OR:2.75, CI:0.88-8.64). Conclusions

Several chronic illnesses coexisted with nocturia. Health care providers need to be aware of an increased risk of nocturia among people with certain chronic illnesses, and provide appropriate health ...
