A lack of effective drugs and technical means to eradicate hepatitis B virus (HBV) is a bottleneck that limits the ability to fully cure HBV infection. Recently, genome-editing technology based on clustered regularly interspaced short palindromic repeats -associated protein 9 is an emerging technique for editing specific gene loci, which can specifically target HBV covalently closed circular DNA, effectively inhibits HBV DNA replication and regulates HBV functional protein expression, and is expected to become a powerful gene therapy tool for the complete eradication of HBV. Considering this, it has become the focus of attention for scholars at home and abroad that how to use clustered regularly interspaced short palindromic repeats -associated protein 9 to accomplish modification of HBV genomes for complete eradication of HBV. This paper summarizes the latest progress based on the latest research results at home and abroad in the application of clustered regularly interspaced short palindromic repeats -associated protein 9 gene editing technology in anti-HBV infection treatment, and expounds its potential and challenges as a radical cure for HBV infection.

Circular RNA (circRNA) is involved in tumor progression. CircPVT1 is an oncogene that is abnormally expressed and correlated with a variety of tumors. It can regulate tumors' malignant behavior and affect the survival and prognosis of patients. This article reviews research on the regulatory roles of circPVT1 in tumors to provide references for accurate treatment.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is one of the common diseases in uroloandrology, which recurs easily after treatment. In recent years, the safety and efficacy of extracorporeal shock wave therapy (ESWT) for CP/CPPS has been widely demonstrated. Studies have shown satisfactory short-term (≤12 weeks) outcomes of ESWT, but lack long-term (>12 weeks) follow-up data. In addition, inconsistent indications and unexplained therapeutic mechanisms have limited the further clinical promotion of ESWT. This article summarizes the latest progress and potential mechanism of ESWT in the treatment of CP/CPPS in order to provide new insights for the standardized application of ESWT.

Background Nitrogen dioxide (NO₂), a crucial component of traffic pollutants, has been shown in studies to exert toxic effects on the nervous system. However, there is a limited body of research examining the relationship between NO₂ exposure and neurological disorders in children. Objective To explore the impact of short-term NO₂ exposure on the outpatient visits due to pediatric neurological diseases in Shijiazhuang. Methods From 2013 to 2021, we collected outpatient data related to neurological diseases at the Children's Hospital in Shijiazhuang, Hebei Province. We also collected air pollution data and meteorological data of the same city. The air pollution data included daily average concentrations of inhalable particles (PM₁₀), fine particulate matter (PM_2.5), sulfur dioxide (SO₂), NO₂, carbon monoxide (CO), and daily maximum 8-hour average concentration of ozone (O₃). The meteorological data comprised daily average atmospheric pressure, temperature, relative humidity, wind speed, and sunshine duration. Employing a time-stratified case-crossover design, we used conditional logistic regression models to analyze the association between NO₂ and pediatric outpatient visits for neurological diseases. Stratification analyses were conducted based on gender (male, female) and age groups (0-6 years, 7-14 years). Results The study included a total of 154348 valid pediatric outpatient visits for neurological diseases. The daily average concentration of NO₂ was 49.3 μg·m⁻³ for the study period. The results from the single-pollutant model indicated that NO₂ increased the risk of pediatric neurological outpatient visits, with the highest association observed at lag0. Specifically, for every 10 μg·m⁻³ increase in atmospheric NO₂ exposure, there was a 1.40% increase (95%CI: 1.05%, 1.74%) in pediatric neurological outpatient visits. The stratification analyses revealed that increased atmospheric NO₂ exposure was associated with an elevated risk of neurological outpatient visits for girls (ER=1.54, 95%CI: 1.01, 2.08) and children aged 7-14 years (ER=2.35, 95%CI: 1.68, 3.02). Even after introducing PM_2.5 (ER=1.96, 95%CI: 1.49, 2.43), SO₂ (ER=2.09, 95%CI: 1.62, 2.55), and O₃ (ER=1.40, 95%CI: 1.06, 1.74) to the models, the impact of NO₂ exposure on pediatric neurological outpatient visits remained statistically significant. The results of the multi-pollutant model also indicated a significant association (ER=2.53, 95%CI: 1.97, 3.08). Conclusion The effect of short-term exposure to atmospheric NO₂ on the outpatient visits of children with neurological diseases in Shijiazhuang is acute and independent, especially for children aged 7-14.
