To compare the feasibility and effectiveness of gum chewing to promote gastrointestinal (GI) recovery and prevent postoperative ileus (POI) in patients who underwent robot-assisted partial nephrectomy (RALPN), all subjects who met the enrollment criteria were randomly divided into the CG group (n = 23) and the control group (n = 29). No intervention other than chewing gum had been set between the two groups. We took the time of first bowel sound, exhaust, defecation, liquid diet, and solid diet as the study endpoints, and performed statistical analysis between the two groups. Baseline and postoperative data of patients were also recorded and analyzed. The time of first flatus, the first defecation, hospital stay, first liquid diet, and first solid diet in the chewing gum group were significantly shorter than those in the control group (all P < 0.05). CG can be an effective approach to promote bowel function recovery and prevent POI after robot-assisted partial nephrectomy.
Bladder cancer is a common tumour of the urinary system, and more than 90% is urothelial carcinoma. Therefore, it is important for discovering the key target genes and molecules of bladder tumour cell metastasis and invasion. Our research initially explored the regulation of deltaN p63 on the progression and metastasis of bladder cancer and found that deltaN p63 can influence the occurrence of EMT through PTEN and ultimately regulate the growth and metastasis of bladder cancer. In summary, this study identified a new EMT regulator, deltaN p63, further revealed the mechanism of the invasion and metastasis of bladder cancer cells, and provided a theoretical basis for finding new target molecules and drugs to treat bladder cancer. In conclusion, this study will further reveal the mechanism of tumour cell invasion and metastasis and provide a theoretical basis for cancer treatment to find new target molecules and drugs.
Objective To explore the short-term efficacy of neoadjuvant endocrine therapy (NET) for localized prostate cancer and preliminary exploration of NET in patients with bone metastases. Methods Analyze clinical data of patients undergoing radical prostatectomy (RP) in the First Affiliated Hospital of Chongqing Medical University from January 2017 to January 2021 retrospectively. Patients with localized prostate cancer undergoing NET+RP were selected as the experimental group. The ones who only received RP were chosen as the control group, and the peri- and post-operative outcomes such as down-staging, pathological complete response, positive margin, intraoperative blood loss, and operation time were compared between the two groups. In addition, collect the information of patients with bone metastatic prostate cancer, excluding organ metastases, who received NET+RP over the same time-period and analyzed the short-term efficacy and quality of life. Results In the experimental group, there were more down-staging (13.08% vs. 4.67%, P=0.031), more pathological complete response (12.15% vs. 0.93%, P=0.001), less positive margin (9.35% vs. 29.91%, P< 0.001) and less blood loss (171.45±16.19 vs. 177.76±23.28, P=0.022). NET+RP also showed a satisfying short-term efficacy in patients with bone metastases, with well quality of life. Conclusion NET combined with RP can provide good short-term prognosis and patient satisfaction in patients with prostate cancer, and it is a potential option for patients with bone metastases without organ metastases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
