Cervical cancer has become an important disease that jeopardizes women′s health, causing hundreds of thousands of new cases annually. Human papillomavirus (HPV) is the leading cause for cervical cancer. Since the world′s first HPV vaccine was licensed in 2006, 92 countries around the world have introduced them in national immunization programs. The WHO recommends that scientific economic evaluation should be achieved before the introduction, but this is more difficult for low-and middle-income countries. Therefore, this article introduces a mathematical model recommended by WHO in 2014 to quickly and easily accomplish economic evaluation of HPV vaccine -the PRIME, and take the China′s 2018 data published by International Agency for Research on Cancer (IARC) as an example. The evaluation result shows that the introduction of HPV vaccine in Chinese 12-year-old women is cost-effective.

Human papillomavirus (HPV) is one of the most common sexually transmitted pathogens. It can cause a variety of diseases such as condyloma acuminatum, anal cancer, penile cancer and oropharyngeal cancer in men, resulting in a high disease burden. With the development of society, the application of HPV vaccines in males has attracted more attention. Currently, there are many clinical trials and real-world research results of HPV vaccines applied to boys and men worldwide, and many countries have introduced HPV vaccination for underage boys into their national immunization programs. This article intended to review the research progress in the efficacy of HPV vaccines in male population.

Exosomes are nanometer-sized vesicles that contain various types of biologically active components, including proteins, nucleic acids, carbohydrates, and lipids, which vary with the type and physiological state of the cell. In recent years, several studies have showed that exosomes can provide new non-invasive diagnostic and prognostic biomarkers in patients affected by cancers, including bladder cancer (BC), and the lipid bilayer membrane structure makes exosomes as promising delivery vehicles for therapeutic applications. Exosomes have the characteristics of high abundance, high stability, tissue specificity, and wide distribution in body fluids, and are secreted as various types by cells in different states, thereby possessing great potential as biomarkers for BC. Herein, we briefly summarize the functions and roles of exosomes in the occurrence and development of BC and the current progress of research on exosomes in BC, while focusing on potential clinical applications of the diagnosis, treatment, and prognosis of BC.
