Radical prostatectomy (RP) is the main therapeutic method for early localized prostate cancer.With the advancement of technology，robot-assisted radical prostatectomy (RARP) is widely applied，which can enable better achievement of the “five wins”, including long-term tumor control，recovery of urinary control，negative surgical margins，preservation of erectile function，and reduced postoperative complications，thereby improving the treatment efficacy.This paper reviews the various surgical approaches (transabdominal，transperitoneal，transvesical，transperineal，single-hole)，current status of optional surgical equipment (da Vinci surgical robot，domestic robot)，and advantages and limitations of RARP，so as to provide reference for clinicians in choosing the optimal surgical method for prostate cancer.

Objective:To investigate the current situation of falls in patients with amyotrophic lateral sclerosis (ALS) and analyze the influencing factors.Methods:A total of 110 ALS patients admitted to Department of Neurology of Peking University Third Hospital from February to April 2023 were selected as the research objects by the convenient sampling method. The Self-designed Patient General Data and Disease-related Questionnaire and Morse Fall Scale (MFS) were used for questionnaire investigation.Results:A total of 100 ALS patients were included, and the incidence of falls in ALS patients was 45.0% (45/100). Binomial Logistic regression analysis showed that gait abnormality, high risk of fall and abnormal muscle strength of lower extremity were risk factors for fall in ALS patients ( P<0.05) . Conclusions:Abnormal gait, high risk of falls and abnormal lower limb muscle strength are independent factors affecting falls in ALS patients, and they are important aspects in preventing and managing falls in ALS patients.

Objective:To explore the application effect of information sharing assisted decision-making intervention in knee replacement patients.Methods:A total of 94 inpatients undergoing knee replacement in Department of Orthopedics in Xinxiang Central Hospital from January to December 2022 were selected by the convenient sampling method, and they were divided into the control group and the observation group according to random number table method, with 47 cases in each group. The control group adopted routine clinical decision-making management, while the observation group implemented information sharing assisted decision-making intervention based on the control group. On the 5th day after surgery, Control Preference Scale (CPS), Chinese version of Preparation Decision Making Scale (PreDM) and Decision Participation Satisfaction Scale were used to evaluate the decision participation, decision readiness and decision satisfaction of patients in two groups.Results:In the control group, active, cooperative and passive decision-making participation accounted for 21.28% (10/47), 27.66% (13/47) and 51.06% (24/47), respectively. In the observation group, 42.55% (20/47), 44.68% (21/47) and 12.77% (6/47) of the participants were active, cooperative and passive, respectively. There was a statistically significant difference in the distribution of decision participation between the two groups ( P<0.01). The PreDM score and decision participation satisfaction score of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.01) . Conclusions:Information sharing assisted decision-making intervention can effectively improve the decision-making participation of knee replacement patients and improve their decision-making readiness and satisfaction.

Objective:To investigate the efficacy of excimer laser atherectomy (ELA) combined with drug-coated balloon (DCB) in the treatment of femoropopliteal arteriosclerosis obliterans (ASO) and its influencing factors.Methods:The clinical data of patients with femoropopliteal ASO treated by ELA combined with DCB from July 2019 to March 2022 were retrospectively analyzed, including technical success rate, ankle-brachial index(ABI), primary patency rate and freedom from target lesion revascularization (TLR) rate. Cox regression was applied to analyze the risk factors affecting the decline in the rate of primary patency and freedom from TLR.Results:All 82 patients were treated with ELA+DCB. The technical success was 91.5%. The post-operative ABI (0.73±0.13) was significantly higher than preoperative ABI (0.39±0.11) ( t=35.26, P<0.001). The 24-month cumulative primary patency and TLR-free rates were 64.1% and 76.8%, respectively. Lesion length>15 cm ( HR=2.57, P=0.047) and severe calcification ( HR=3.26, P=0.021) were associated with loss of primary patency. Having diabetes ( HR=5.24, P=0.010) and a single postoperative outflow tract ( HR=4.18, P=0.008) were associated with a decrease in TLR-free rates. Conclusions:ELA combined with DCB for femoropopliteal ASO is safe and has good intermediate efficacy. Lesion length>15 cm and severe calcification were independent risk factors for primary patency rate, and diabetes and a single postoperative outflow tract were independent risk factors for TLR-free rate.

Objective To evaluate the efficacy and safety of laser-assisted balloon angioplasty(LABA)in treating patients with infrapopliteal arterial occlusion complicated by critical limb ischemia(CLI).Methods The clinical data of patients with infrapopliteal artery occlusion complicated by CLI,who were admitted to the Fuwai Central China Cardiovascular Hospital to receive LABA(LABA group)or balloon angioplasty alone(BA group)between January 2019 and December 2021,were retrospectively analyzed.The incidence of perioperative complications and postoperative clinical efficacy were compared between the two groups.Results A total of 32 patients received LABA therapy and 40 patients received BA alone.The technical success rate,the postoperative ankle-brachial index(ABI),the numerical value of postoperative ABI value deducting preoperative ABI value,the postoperative 24-month continuous improvement rate of clinical symptoms and the primary patency rate of target vessels in the LABA group were remarkably higher than those in the BA group(all P＜0.05).No procedure-related target vessel perforation,amputation,or death occurred in both groups.No statistically significant differences in the target vessel dissection,distal embolism,remedial stenting,and postoperative 24-month amputation-free survival existed between the groups(all P＞0.05).Conclusion For the infrapopliteal arterial occlusion complicated by CLI,LABA therapy is clinically safe and effective,and its mid-term efficacy is superior to BA alone.

Objective:To analyze the research hotspots and frontier issues in the field of radioactive particle implantation nursing and protection in China, so as to provide reference for future research directions.Methods:From January 1, 2001 to December 31, 2020, the literature on nursing and protection of radioactive particle implantation in China National Knowledge Infrastructure (CNKI), WanFang Data and VIP were retrieved. NoteExpress 3.2 was used to remove duplicate literature, and Microsoft Excel 2019 was used to draw charts. The year of publication, published journal, cited frequency, research type, disease distribution, regional distribution, research institutions and fund support were extracted for classification, and high frequency keywords were analyzed with CiteSpace 5.8.R1.Results:Finally, 659 articles, 572 articles on nursing, 79 articles on protection and 8 articles on protection and nursing were included. In 2011, the number of articles was the largest. Jiangsu, Guangdong, Shandong and Beijing had the largest number of articles. Among the articles, experimental research accounted for 6.98%, funded projects accounted for 6.68%, and the co-authorship rate was 65.40%. The diseases studied involved multi system tumors, and the single disease articles mainly included lung cancer, liver cancer and prostate cancer. From 2015 to 2016, radiation protection became a research hotspot, and continuous nursing received high attention in recent five years.Conclusions:In recent 20 years, the quality of research on the nursing and protection of radioactive particle implantation in China is relatively low. It is necessary to strengthen regional cooperation and carry out multicenter research. Continuous nursing should combine the needs of patients, give play to the advantages of network platform, and focus on multi-dimensional nursing outcomes including protection education.
