Objective To compare the efficacy and safety of transurethral blue laser vaporization of the prostate, transurethral resection of the prostate (TURP) or plasmakinetic resection of the prostate in the treatment of benign prostatic hyperplasia (BPH). Methods The domestic and foreign clinical studies on transurethral blue laser vaporization of the prostate (observation group), TURP or plasmakinetic resection of the prostate (control group) in the treatment of BPH during Jan. 2015 and Mar. 2025 were retrieved. The data were extracted with Cochrane systematic review method. The operation time, decrease in hemoglobin, bladder irrigation time, catheter indwelling time, total complication rate, retrograde ejaculation rate and urinary incontinence rate of the two groups were compared with RevMan 5.3.0 statistical software. Results A total of 5 Chinese studies involving 491 patients (248 in the observation group and 243 in the control group) were included in the Meta-analysis. Compared with the control group, the observation group had shorter operation time [MD=-20.80, 95%CI:-26.88—-14.72, P＜0.00001], less decrease in hemoglobin [MD=-10.61, 95%CI: -20.21—-1.01, P=0.03], shorter bladder irrigation time [MD=-17.85, 95%CI: -32.62—-3.09, P=0.002], shorter catheter indwelling time [MD=-1.71, 95%CI: -2.81—- 0.62, P=0.002], lower total complication rate [OR=0.11, 95%CI: 0.06—0.21, P＜0.00001], lower retrograde ejaculation rate [OR=0.05, 95%CI: 0.02—0.16, P＜0.00001] and lower urinary incontinence rate [OR=0.24, 95%CI: 0.07—0.79, P=0.02]. There were no significant differences in other complications between the two groups (P＞0.05). The international erectile function score (IIEF-5) of the observation group was significantly higher than that of the control group [MD=1.87, 95%CI:1.16—2.57, P＜0.00001]. There were no significant differences in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax) and post-voiding residual (PVR) between the two groups (P＞0.05). Conclusion All three surgical procedures can effectively improve the lower urinary tract symptoms of BPH patients. Compared with TURP or plasmakinetic resection of the prostate, transurethral blue laser vaporization of the prostate has obvious advantages in terms of perioperative recovery, reduction of total complications, urinary incontinence and retrograde ejaculation rates, and preservation of sexual function.

Cardiac arrest (CA) is a critical condition in the field of cardiovascular medicine. Despite successful resuscitation, patients continue to have a high mortality rate, largely due to post CA syndrome (PCAS). However, the injury and pathophysiological mechanisms underlying PCAS remain unclear. Experimental animal models are valuable tools for exploring the etiology, pathogenesis, and potential interventions for CA and PCAS. Current CA animal models include electrical induction of ventricular fibrillation (VF), myocardial infarction, high potassium, asphyxia, and hemorrhagic shock. Although these models do not fully replicate the complexity of clinical CA, the mechanistic insights they provide remain highly relevant, including post-CA brain injury (PCABI), post-CA myocardial dysfunction (PAMD), systemic ischaemia/reperfusion injury (IRI), and the persistent precipitating pathology. Summarizing the methods of establishing CA models, the challenges encountered in the modeling process, and the mechanisms of PCAS can provide a foundation for developing standardized CA modeling protocols.
