AI Article Synopsis
- The study compared the safety and effectiveness of two laser treatments—120-W HPS GreenLight KTP and 2-micrometer continuous-wave (CW)—for benign prostatic hyperplasia (BPH) in 414 patients.
- Both laser techniques successfully treated BPH with no major complications, and the improvement in symptoms and urinary function was significant and similar in both groups over 24 months.
- The 120-W KTP laser group had shorter average catheterization and hospitalization times, but a higher incidence of discomfort like dysuria and urge incontinence was noted in the 2-micrometer CW laser group.
Article Abstract
Objective: To evaluate safety, efficacy, and long-term outcomes of photoselective vaporization of prostate using 120-W HPS GreenLight KTP laser and compare the results with those obtained with 2-micrometer continuous-wave (2 um CW) laser for treatment of patients with benign prostatic hyperplasia (BPH).
Materials And Methods: One group of 216 patients diagnosed with BPH underwent 120-W KTP laser vaporization of the prostate, while another group of 198 BPH patients underwent 2 um CW laser vaporization. The relevant pre-, peri-, and post-operative parameters were compared between the two therapy groups. Functional results in terms of improvement of International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), and post-void residual (PVR) urine were assessed at 3, 6, 12, and 24 months.
Results: BPH was successfully treated with 120-W HPS KTP laser and 2 um CW laser in all patients. There were no significant difference between two patient groups in the baseline characteristics (such as PSA, IPSS, QoL, and Qmax). No major complications occurred intraoperatively (capsule perforation and TUR syndrome) or postoperatively (electric unbalance), and no blood transfusions were required in both groups. Average catheterization time was 1.9±1.3 days for the 120-W PVP and 2.2±1.9 days for the 2 um CW laser treatment. In addition, the hospitalization times were 3.8±1.2days (120-W PVP) and 4.8±1.5 days (2 um CW laser), respectively. The incidence of dysuria and urge incontinence was higher in the 2 um CW laser group (35/198, 24/198) than in the 120 W PVP group (15/216, 10/216). Dramatic improvement was observed in Qmax, IPSS, Qol, and PVR as compared with the respective pre-operative values. The degree of improvement during the follow-up period was comparable in both groups. No significant differences were observed in terms of re-operation rates, bladder neck stricture, and urethral stricture.
Conclusions: Both 120-W HPS laser and 2 um CW laser vaporization present effective treatment options in patients with BPH, but 120-W PVP provides safer therapy with less post-operative complications within the 2-year follow-up period.

Background: Endodontic treatment aims in the preservation of extremely carious primary teeth. For root canal therapy to be successful, root canals must be properly prepared and effectively irrigated .Therefore, it is necessary to select the proper root canal disinfection method to preserve the primary tooth.

African swine fever (ASF) is an acute hemorrhagic disease in pigs caused by the African swine fever virus (ASFV), which has a high mortality rate and brought great damage to global pig farming industry. At present, there is no effective treatment or vaccine to combat ASFV infection, so early detection of ASFV has become particularly important. Therefore, the PDMS/chitosan/MPMs composite film was proposed to detect ASFV P72.

Repeated closed-head injuries (rCHI) from activities like contact sports, falls, military combat, and traffic accidents pose a serious risk due to their cumulative impact on the brain. Often, rCHI is not diagnosed until symptoms of irreversible brain damage appear, highlighting the need for preventive measures. This study assessed the prophylactic efficacy of remote photobiomodulation (PBM) targeted at the lungs against rCHI-induced brain injury and associated behavioral deficits.

Hypoxic tumors present a significant challenge in cancer therapy due to their ability to adaptation in low-oxygen environments, which supports tumor survival and resistance to treatment. Enhanced mitophagy, the selective degradation of mitochondria by autophagy, is a crucial mechanism that helps sustain cellular homeostasis in hypoxic tumors. In this study, we develop an azocalix[4]arene-modified supramolecular albumin nanoparticle, that co-delivers hydroxychloroquine and a mitochondria-targeting photosensitizer, designed to induce cascaded oxidative stress by regulating mitophagy for the treatment of hypoxic tumors.

Objective: This study aimed to explore the cumulative effects and expression patterns of electroacupuncture (EA) on irisin secretion, observe the effects of EA on the recovery of neurobehavioral function and vascular remodeling after cerebral ischemia, and elucidate the mechanism by which EA promotes vascular remodeling by regulating irisin expression.
Methods: A rat model of left middle cerebral artery occlusion (MCAO) was prepared, and EA was performed. Tissue distribution and expression of irisin were determined by immunofluorescence, enzyme-linked immunosorbent assay (ELISA), and Western blotting.
