Background: Actinic cystitis is a severe complication after radiotherapy for prostate cancer. It is a chronic inflammatory process that leads to an alteration of bladder mucosa with formation of petechiae and subsequently hematuria. Actinic cystitis responds poorly to medical treatment, with a heavy burden on patients' quality of life. Patients with refractory hematuria may undergo cystectomy in the attempt to control bleeding. We conducted a prospective study to evaluate the effectiveness of the allogeneic platelet growth factors for actinic cystitis.
Methods And Material: Nine patients with actinic cystitis were enrolled in this study. The primary outcome measures were the effects of the platelet growth factors on the injury of the bladder mucosa. The secondary outcome was the change in quality of life RESULTS: A total of 9 patients, mean age 68 (range 59-81) underwent a therapeutic program of bladder instillation with allogeneic platelets growth factors for 3 months. Of the 9 patients, all (100 %) had complete resolution of hematuria and urinary symptoms. After three months cystoscopy showed regeneration of the normal bladder mucosa. Biopsies allowed histological confirmation of the finding.
Discussion: The instillation of allogeneic platelet growth factors in actinic cystitis is a new treatment that in this setting of patients appears promising in promoting a resolution of urinary symptoms, hematuria and avoiding a disabling surgery such as cystectomy.

Background: Major decision-making self-efficacy (MDMSE) is an important indicator of students' ability to make effective decisions in specialty selection. It has implications for students' personal growth and career counselling interventions. While the previous MDMSES has been widely used in the context of China's New College Entrance Examination reform, the increased choice of majors and advancement of career planning necessitate a new scale to assess high school students' MDMSE levels.

Infection with Influenza A virus (IAV) induces severe inflammatory responses and lung injury, contributing significantly to mortality and morbidity rates. Alterations in the microbial composition of the lungs and intestinal tract resulting from infection could influence disease progression and treatment outcomes. Xiyanping (XYP) injection has demonstrated efficacy in clinical treatment across various viral infections.

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most harmful pathogens in the swine industry. Our previous studies demonstrated that the small extracellular domain (ECL2) of CLDN4 effectively blocks PRRSV infection. In this study, we explored the in vivo administration of swine ECL2 (sECL2) and found that it blocked HP-PRRSV infection and alleviated histopathological changes in organs.

Growing evidence implicates that intratumoral microbiota are closely linked to cancer progression; however, research on the role of these microbiota in the development of gastric cancer remains limited. Here, using 16 S rRNA sequencing, tumor tissue proteomics and serum cytokines analysis, we identified enrichment of specific microbial communities within tumors of gastric cancer patients, possibly affecting the tumor microenvironment by immune modulation, metabolic processes, and inflammatory responses. Based on the results of in vivo experiments and intratumoral microbiota analysis, we found that Streptococcus mitis can inhibit gastric cancer progression via suppressing M2 macrophage polarization and infiltration, as well as altering the intratumoral microbial community.
