In prostate cancer, castration resistance is a factor that frequently leads to death in individuals with this disease. Recent studies have suggested that prostate cancer stem cells (PCSCs) are pivotal regulators in the establishment of castration resistance. The nanog homeobox (NANOG) and the transforming growth factor (TGF)-β1/drosophila mothers against decapentaplegic protein (SMAD) signaling pathways are involved in several cancer stem cells but are not involved in PCSCs. The purpose of this study is to investigate the effect of NANOG on the proliferation of PCSCs regulated by the TGF-β1/SMAD signaling pathway.

In this study, we used flow cytometry to isolate CD44+/CD133+/NANOG+ PCSCs from DU145 prostate cancer cells. Then we used short hairpin RNA to silence NANOG and observed the biological behavior and the TGF-β1/SMAD signal of PCSCs.

NANOG decreased PCSC proliferation, increased apoptosis, and blocked cell cycling at G0/G1. Furthermore, reduction in the TGF-β1, p15, and p-SMAD2 expression was observed.

These findings suggest that NANOG positively regulates the growth of PCSCs through the TGF-β1/SMAD signaling pathway.

Then the role of IGF-1 was explored in HVFs and thiazolyl blue tetrazolium bromide (MTT) and flow cytometry were used to detect cell viability and cell apoptosis. Western blot assay and quantitative real-time polymerase chain reaction were used to detect the protein and mRNA expression. The results showed that knockdown of IGF-1 inhibited the cell viability of HVFs, promoted the cell apoptosis of HVFs, and decreased the expression of types I and III collagen in HVFs, which was through inhibiting the expression of IGF-1 receptor and MAPK/NF-κB pathways. However, IGF-1 plasmid had the opposite effects on HVFs. In conclusion, our results showed that IGF-1 could activate MAPK and NF-κB pathways, thereby enhancing collagen metabolism and the growth of vaginal wall fibroblasts then to inhibit POP development.During radiotherapy treatment for cervical cancer, up to 84% of patients exhibit some form of acute radiation toxicity (ART). The primary aim of this clinical study is to determine the impact of angiotensin-converting enzyme (ACE) inhibitors, β-blockers and other risk factors such as the patient's anatomical characteristics on ART emergence in patients with locally advanced cervical cancer treated by chemoradiotherapy. This is a combination of two nested case-control studies within the cohort of patients with locally advanced cervical cancer based on the analysis of potential risk factors for the onset of ART in patients treated with 3D conformal radiotherapy (3D-CRT) and 2D conventional radiotherapy (2D-RT), prospectively followed up from January 2017 to September 2018 in a tertiary care hospital. The ACE inhibitors and bladder volume were identified as factors that significantly affect the occurrence of ART in patients treated with 3D-CRT. In patients treated with 2D-RT, the factors that significantly affect the occurrence of ART were ACE inhibitors, body mass index (BMI), brachytherapy rectal and bladder dose. This study has shown that BMI, radiation dose received by the bladder and rectum are of exceptional importance for the occurrence of the ART and also that therapy with ACE inhibitors was associated with the decreased chances of the ART.Procedural sedation and analgesia (PSA) is important during painful dilatation and stenting in patients undergoing percutaneous trans-hepatic biliary drainage (PTBD). A prospective, nonblinded randomized clinical trial was performed comparing different analgesic regimens with regard to the patient's comfort. Patients were randomly assigned to two treatment groups in a parallel study, receiving either remifentanil or combined midazolam, piritramide, and S-ketamine. The primary study endpoint was pain intensity before, during, and after the intervention using the numerical rating scale (0, no pain; 10, maximum pain). The secondary study endpoint was the satisfaction of the interventional radiologist. Fifty patients underwent PTBD of whom 19 (38.0%) underwent additional stenting. During intervention, the two groups did not differ significantly. After the intervention, the need for auxiliary opioids was higher (12.5% vs 7.7%; p = 0.571) and nausea/vomiting was more frequently observed (33.4% vs 3.8%; p = 0.007) in patients with remifentanil than in patients with PSA. Overall, 45 patients (90.0%) needed additional administration of non-opioid analgesics during postinterventional observation. Remifentanil and combined midazolam, piritramide, and S-ketamine obtained adequate analgesic effects during PTBD. After the intervention, medications with antiemetics and long-acting analgesics were more frequently administered in patients treated with remifentanil (EudraCT No. 2006-003285-34; institutional funding).
Early diagnosis and treatment are crucial for the survival of severe Coronavirus Disease 2019 (COVID-19) patients, but data with regard to risk factors for disease progression from milder COVID-19 to severe COVID-19 remain scarce.

We conducted a retrospective analysis on 116 patients.

Three factors were observed to be independently associated with progression to severe COVID-19 during 14 days after admission (a) age 65 years or older (hazard ratio [HR] = 8.456; 95% CI 2.706-26.426); (b) creatine kinase (CK) ≥ 180 U/L (HR = 3.667; 95% CI 1.253-10.733); and (c) CD4+ T-cell counts <300 cells/µL (HR = 4.695; 95% CI 1.483-14.856). The difference in rates of severe COVID-19 development was found to be statistically significant between patients aged 65 years or older (46.2%) and those younger than 65 years (90.2%), between patients with CK ≥ 180 U/L (55.6%) and those with CK < 180 U/L (91.5%), and between patients with CD4+ T-cell counts <300 cells/µL (53.8%) and those with CD4+ cell counts ≥300 cells/µL (83.
