Objective To explore and compare the efficacy and safety of different transurethral enucle-ation procedures for treating benign prostatic hyperplasia.Methods A retrospective analysis was conducted on the clinical data of 215 patients with benign prostatic hyperplasia admitted to our hospital from January 2021 to May 2023.According to the surgical procedures,they were divided into plasma resection group(n=81),treated with transurethral plasma resection of the prostate,laser resection group(n=92),treated with transurethral laser resection of the prostate,and green laser enucleation group(n=42),treated with transurethral green laser enucle-ation of the prostate.The three groups were compared in terms of perioperative indicators(surgical time,intraop-erative bleeding volume,bladder flushing time,indwelling catheter time,postoperative hemoglobin concentration,and hospital stay),urodynamic indicators(RUV,IPSS score,Qmax,and QOL score),and postoperative compli-cations.Results The green laser enucleation group and laser resection group demonstrated a significantly higher total effective rate compared to the plasma electrosurgery group(P<0.05).The three groups showed no statisti-cally significant difference in hospital stay(P>0.05),but the green laser enucleation group showed a signifi-cantly shorter surgical time compared to the other two group(P<0.05).The green laser enucleation group and laser resection group had superiority in intraoperative bleeding,bladder flushing time,and indwelling catheter time compared to the plasma resection group,and a significantly higher postoperative hemoglobin concentration compared to the plasma resection group(P<0.05).Repeated measurement analysis of variance showed that the three groups all exhibited significantly decreases in RUV,IPSS score,and QOL score(P<0.05),and a signifi-cantly increase in Qmax at 1 month and 3 months after surgery(P<0.05).The laser resection group and green laser enucleation group presented with significant decreases in RUV,IPSS score,and QOL score(P<0.05),and a significantly decrease in Qmax compared to the plasma resection group at 1 month and 3 months after surgery(P<0.05).However,the laser resection group and the green laser enucleation group had no statistically signifi-cant difference in RUV,IPSS score,Qmax,and QOL score at 1 month and 3 months after surgery(P>0.05).The green laser enucleation group had the lowest total incidence of postoperative complications,following by the laser resection group and plasma resection group in order(7.14%vs.21.74%vs.35.80%,P<0.05).Conclusion The three surgical procedures all have good therapeutic effects on benign prostatic hyperplasia.Transurethral laser prostatectomy and green laser enucleation have superiority to those of transurethral plasma resection of the prostate in efficacy and safety,and they can promote early recovery of patients.Transurethral green laser enucleation is the best in safety.

Objective: This study aimed to investigate risk perception among first-degree relatives (FDRs) of patients with colorectal cancer (CRC) and to analyze influencing factors. Methods: 406 FDRs of CRC patients were selected as the participants through convenience sampling. A cross-sectional survey was conducted using the Hamilton Anxiety Scale, Colorectal Cancer Risk Perception Assessment Scale, and Colorectal Cancer Health Belief Scale, and relevant influencing factors were analyzed using univariate analysis and multiple linear regression analysis. Results: Participants had an average age of 41.90±14.76 years. The composition of participants included siblings at 45.9%, parents at 4.2%, and children at 49.4%. The risk perception score of 2.80±0.96 was obtained from participants. The Pearson correlation analysis results demonstrated that the total anxiety score of participants was positively correlated with the total risk perception score (r=0.39, p<.001), and the health belief score was also positively correlated with the risk perception score (r=0.49, p<.001). Moreover, the multiple regression analysis results revealed that the risk perception of participants was mainly affected by their education level, monthly household income per person, health beliefs, and level of anxiety (R2 =0.34, F=21.92, p<.001). Conclusion Healthcare professionals should place greater emphasis on assessing risk perception among participants, with a particular focus on those with lower education levels, lower incomes, and weaker health beliefs. They should also promptly monitor changes in family members' emotions and develop personalized clinical intervention plans based on individual characteristics, aiming to enhance this group's risk awareness and prevent the onset of disease.

Objective: To investigate the prevalence of diabetes among individuals at high risk of diabetes in Baoshan District, Shanghai Municipality, so as to provide insights into community-based diabetes management. Methods: Permanent residents at ages of 35 years and older were sampled from Baoshan District using a multistage stratified cluster sampling method, and residents at a high risk of diabetes were screened using the Form for Risk Assessment of Diabetes among Community Residents in Shanghai Municipality. Participants' demographics, disease history and history of medication were collected using questionnaire surveys, and height, body weight, waist circumference, hip circumference, and blood pressure were measured. Diabetes was screened using fasting blood glucose and glucose tolerance test. The factors affecting the development of diabetes were identified among high-risk residents for diabetes using a multivariable logistic regression model. Results: A total of 3 107 residents at a high risk for diabetes were enrolled, including 1 165 men (37.50%) and 1 942 women (62.50%) with a mean age of (63.58±9.77) years. The prevalence of diabetes was 21.69% among the study subjects, and multivariable logistic regression analysis showed that men (OR=1.689, 95%CI: 1.357-2.104), age (40 years-, OR=4.833, 95%CI: 1.036-22.553; 50 years-, OR=2.627, 95%CI: 1.432-4.819; 60 years-, OR=1.551, 95%CI: 1.119-2.150; 70 years and older, OR=1.579, 95%CI: 1.232-2.025); high school/technical secondary school (OR=2.677, 95%CI: 1.636-4.380), overweight/obesity (OR=1.891, 95%CI: 1.447-2.472), hypertension (OR=1.306, 95%CI: 1.049-1.626), dyslipidemia (OR=1.428, 95%CI: 1.114-1.831), history of impaired glucose regulation (OR=15.161, 95%CI: 11.827-19.434) and family history of type 2 diabetes mellitus (OR=2.092, 95%CI: 1.619-2.704) caused an increased risk of diabetes among residents at a high risk diabetes. Conclusions The prevalence of diabetes was 21.69% among high-risk populations of diabetes in Baoshan District. Gender, age, educational level, overweight/obesity, hypertension, dyslipidemia, history of impaired glucose regulation and family history of type 2 diabetes mellitus are factors affecting the development of diabetes among high-risk populations.

CRISPR, as an emerging gene editing technology, has been widely used in multiple fields due to its convenient operation, less cost, high efficiency and precision. This robust and effective device has revolutionized the development of biomedical research at an unexpected speed in recent years. The development of intelligent and precise CRISPR delivery strategies in a controllable and safe manner is the prerequisite for translational clinical medicine in gene therapy field. In this review, the therapeutic application of CRISPR delivery and the translational potential of gene editing was firstly discussed. Critical obstacles for the delivery of CRISPR system in vivo and shortcomings of CRISPR system itself were also analyzed. Given that intelligent nanoparticles have demonstrated great potential on the delivery of CRISPR system, here we mainly focused on stimuli-responsive nanocarriers. We also summarized various strategies for CIRSPR-Cas9 system delivered by intelligent nanocarriers which would respond to different endogenous and exogenous signal stimulus. Moreover, new genome editors mediated by nanotherapeutic vectors for gene therapy were also discussed. Finally, we discussed future prospects of genome editing for existing nanocarriers in clinical settings.

Near-infrared (NIR)-light-triggered nanomedicine, including photodynamic therapy (PDT) and photothermal therapy (PTT), is growing an attractive approach for cancer therapy due to its high spatiotemporal controllability and minimal invasion, but the tumor eradication is limited by the intrinsic anti-stress response of tumor cells. Herein, we fabricate a tumor-microenvironment responsive CRISPR nanoplatform based on oxygen-deficient titania (TiO_2-x ) for mild NIR-phototherapy. In tumor microenvironment, the overexpressed hyaluronidase (HAase) and glutathione (GSH) can readily destroy hyaluronic acid (HA) and disulfide bond and releases the Cas9/sgRNA from TiO_2-x to target the stress alleviating regulators, i.e., nuclear factor E2-related factor 2 (NRF2) and heat shock protein 90α (HSP90α), thereby reducing the stress tolerance of tumor cells. Under subsequent NIR light illumination, the TiO_2-x demonstrates a higher anticancer effect both in vitro and in vivo. This strategy not only provides a promising modality to kills cancer cells in a minimal side-effects manner by interrupting anti-stress pathways but also proposes a general approach to achieve controllable gene editing in tumor region without unwanted genetic mutation in normal environments.

Objective Collect and analyze data of radiation level of ²¹⁰Po/²¹⁰Pb in cigarettes in China, evaluate the internal radiation dose caused by smoking to Chinese smokers and compare it with other countries. Methods The radiation levels of ²¹⁰Po/²¹⁰Pb in cigarettes in domestic and foreign countries were summarized and analyzed, and the fractions of ²¹⁰Po/²¹⁰Pb in mainstream smoke were recommended, and the internal radiation doses to smokers in China were estimated. Results In 2015, there were 320 million smokers among aged 15 and above in China with an average smoking amount of 15.2 cigarettes per day. The average activities of ²¹⁰Po/²¹⁰Pb weighted by the number of cigarette brands were 28.2 mBq per cigarette and 39.3 mBq per cigarette respectively. The mainstream smoke fraction of 20% of ²¹⁰Po was used to make the does estimation which was the mean value of the experimental results of simulator and volunteers, and that of ²¹⁰Pb was 10% measured by simulators. Based on the average smoking amount per day and the number of smokers in China, the annual effective dose of current smokers in China is 126 μSv·a⁻¹, and the collective effective dose is 40746 man·Sv. Conclusion The content of ²¹⁰Po/²¹⁰Pb in Chinese cigarettes is about 2～3 times that of other country's cigarettes. However, the fraction of mainstream smoke and dose conversion coefficient of ²¹⁰Po/²¹⁰Pb adopted in this paper are different from those in other literatures. Therefore, the estimated dose of 20 cigarettes for Chinese smokers is lower than that for smokers in some countries.
