PurposeThis study is aimed to investigate the specific regulatory role of S100 calcium binding protein A11 (S100A11) on cervical cancer (CC), and reveal the potential mechanisms relating to Wnt/β-catenin signaling.Patients and methodsThe expression of S100A11 in cervical squamous cell carcinoma (CSCC), adjacent non-cancerous, cervical intraepithelial neoplasia (CIN), and normal cervical tissues was detected by quantitative real-time PCR and/or immunohistochemistry. After transfection of pENTER-S100A11 or sh-S100A11-1/sh-S100A11-2, the viability, cell cycle, migration and invasion of C33A or SiHa cells were detected. The tumor volume and tumor weight were measured after injection of transfected C33A cells into mice. The expression of E-caherin (CDH2), N-caherin (CDH1), β-catenin (CTNNB1), and c-Myc (MYC) in C33A and SiHa cells was detected by Western blot.ResultsThe expression of S100A11 was significantly higher in CSCC tissues than in adjacent non-cancerous, CIN, and normal cervical tissues (P < 0.05). S100A11 expression was positively correlated with the FIGO stage and lymph node metastasis of CSCC patients (P < 0.05). The transfection of pENTER-S100A11 into C33A cells significantly increased the cell viability, the percentage of cells in G2/M phase, the numbers of migratory and invasive cells, as well as the tumor volume and weight in mice (P < 0.05). Overexpression of S100A11 also significantly downregulated E-caherin, and upregulated N-caherin, β-catenin, and c-Myc in C33A cells (P < 0.05). The transfection of sh-S100A11-1/sh-S100A11-2 exhibited the opposite results to that of pENTER-S100A11 on SiHa cells.ConclusionOverexpression of S100A11 promotes the proliferation, migration, invasion, and epithelial-mesenchymal transition of CC cells, and activates Wnt/β-catenin signaling.

Objective: Cervical cancer is a common gynecologic cancer, and no study has been reported on the way through which lncRNA SNHG1, miR-195 and NEK2 jointly affect cervical cancer cells (CCCs), so this paper will explore a new approach to the development of cervical cancer in this respect. Methods: Altogether 72 cervical cancer tissues and 54 adjacent tissues were collected. qPCR was performed to quantify lncRNA SNHG1 and miR-195, whose expression vectors were constructed and then transfected into CCCs, so as to observe their effects on the cells. Western blotting (WB) was carried out to detect protein levels. MTT assay was conducted to detect cell activity. Flow cytometry was performed to detect cell apoptosis. Transwell was carried out to detect cell invasion and migration. Results: The expression of lncRNA SNHG1 up-regulated while that of miR-195 downregulated in CCCs. lncRNA SNHG1 regulated NEK2 through its targeted binding to miR-195. The down-regulation of lncRNA SNHG1 or the up-regulation of miR-195 led to the decrease of NEK2 and the reduction of cells' activity, migration and invasion, also resulting in the increase of cell apoptosis. Rescue experiments showed that the down-regulation of miR-195 could offset the cell changes caused by lncRNA SNHG1. Conclusion: lncRNA SNHG1 promotes the progression of cervical cancer through the miR-195/NEK2 axis, so lncRNA SNHG1, miR-195 and NEK2 may have potential values for diagnosing and treating cervical cancer.

Objective. To investigate the application and effect of the nurse-led “outpatient-ward-home” management model in the care of patients with chronic kidney disease (CKD). Methods. 120 patients with CKD admitted to our hospital between April 2020 and April 2021 were selected as trial subjects. All patients were divided into experimental and control groups according to the random number table method, with 60 cases in each group. The patients in the experimental group implemented the nurse-led “outpatient-ward-home” management model; the patients in the control group were given routine care and telephone follow-up. The self-rating anxiety scale (SAS), self-rating depression scale (SDS), Pittsburgh Sleep Quality Index (PSQI) score, self-management scores, nutritional status, renal function indicators, and chronic renal failure quality of life scale (QLICD-CRF2.0) were compared between the two groups before and 6 months after the intervention. Results. Before the intervention, there were no statistically significant differences between the control and experimental groups in SAS, SDS, PSQI scores, self-management scores, QLICD-CRF2.0 scores, body mass index (BMI), prealbumin (PAb), albumin (ALB), serum creatinine (Scr), blood urea nitrogen (BUN), and glomerular filtration rate (GFR) levels ( P > 0.05 ). After 6 months of intervention, SAS, SDS, PSQI scores, Scr, BUN, and GFR levels were lower in the experimental group than in the control group; self-management scores, QLICD-CRF2.0 scores, BMI, PAb, and ALB levels were higher in the experimental group than in the control group ( P < 0.05 ). Conclusion. The nurse-led “outpatient-ward-family” intervention model can improve the negative emotions and sleep disorders of CKD patients, enhance patients’ self-management ability, and to a certain extent, slow down the disease process and improve the quality of life.
