Effect of Essential Oil on Patients with Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Pilot Randomized Controlled Trial

Objective: To evaluate the efficacy and safety of essential oil treatment for type Ⅲ chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS). Methods: A randomized controlled trial was conducted from December 2014 to October 2015. Seventy type Ⅲ CP/CPPS patients were assigned to the essential oil group(35 cases) or almond placebo oil control group(35 cases) by a random number table. The oil was smeared by self-massage on the suprapubic and sacral region once a day for 4 weeks. The National Institutes of Health Chronic Prostatitis Syndrome Index(NIH-CPSI) and expressed prostatic secretions(EPS) were examined. The primary outcome was NIH-CPSI pain domain. The secondary outcomes included other NIH-CPSI domains and laboratory examinations of EPS. Adverse events were also observed. Results: Sixty-six subjects completed the full 4-week treatment. There was no significant difference between almond oil control and essential oil groups in terms of the total score of NIH-CPSI, pain, quality of life and urination domain scores of NIH-CPSI and EPS examinations(P0.05). In the essential oil group, pain between rectum and testicles(perineum) in the domain of pain or discomfort was significantly reduced at week 2 and week 4 compared with almond oil control group(P0.01). No serious adverse events occurred. Conclusion: The essential oil may reduce the pain or discomfort in the perineum region in patients with CP/CPPS.     

Constructing novel molecular subtypes and an 11-gene signature based on pyroptosis signaling for lung adenocarcinoma

Pyroptosis plays important roles in various cancers. In this study, we focused on lung adenocarcinoma (LUAD) and aimed to develop new molecular subtypes based on pyroptosis signaling. Pyroptosis-related genes were used as a basis to classify molecular subtypes through unsupervised consensus clustering. Gene set enrichment analysis was performed to characterize tumor microenvironment (TME) and functional pathways. Univariate Cox regression and least absolute shrinkage and selection operator (LASSO) analysis were conducted to identify prognostic genes for establishing a prognostic model. Three molecular subtypes were established with distinct overall survival, TME and enriched pathways. C3 subtype had the longest survival and the highest immune infiltration. 11 prognostic genes were screened to build a prognostic signature for predicting LUAD prognosis. This study emphasized the important role of pyroptosis in LUAD development. Pyroptosis was considered to play critical roles in regulating TME. Moreover, the 11-gene signature could serve as an indicator for predicting LUAD prognosis, and was potential targets for developing targeted drugs.
