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:To investigated the correlation between vascular remodeling pattern and perforator stroke after stenting in patients with symptomatic intracranial vertebrobasilar artery stenosis.Methods:Patients with symptomatic intracranial vertebrobasilar atherosclerotic stenosis underwent stenting and high resolution magnetic resonance imaging (HR-MRI) from January 2017 to August 2020 were enrolled retrospectively. The data of demography, vascular risk factors, plaque characteristics, operation process and postoperative complications were collected. The plaque characteristics were observed by HR-MRI, and the correlation between vascular remodeling pattern and perforator stroke after stenting was analyzed.Results:A total of 41 patients were enrolled in the analysis. Their age was 60.1±8.8 years (range, 49-77 years). There were 31 males (75.6%). Among them, 21 (51.2%) were positive remodeling, 20 (48.8%) were non-positive remodeling, and 5 (12.2%) had perforator stroke after procedure. The incidence of perforator stroke in the positive remodeling group was significantly higher than that in the non-positive remodeling group (23.8% vs. 0%; P=0.048). The positive remodeling rate of the perforator stroke group was significantly higher than that of the non-perforator stroke group (100.0% vs. 44.4%; P=0.048). Conclusions:Patients with intracranial vertebrobasilar atherosclerotic stenosis and positive vascular remodeling were more likely to have perforator stroke after stenting.

Objective:To investigate the significance of CT imaging features in the diagnosis of first-episode paranoid schizophrenia.Methods:Forty-five patients with first-episode paranoid schizophrenia admitted to Shaoxing 7 th People's Hospital from January 2018 to January 2019 were included in the study group. An additional 40 healthy controls who received health examination were included in the control group. All participants underwent head CT scans and CT values of cerebral lobes were measured. CT imaging features of first-episode paranoid schizophrenia were analyzed. The recurrence rate of paranoid schizophrenia was calculated. The diagnostic effect of CT imaging on paranoid schizophrenia was evaluated. Results:The CT value of the frontal lobe in the study group was significantly lower than that in the control group [(33.1 ± 1.4) HU vs. (36.9 ± 2.1) HU, t = 9.914, P < 0.001]. The proportions of patients having ventricular enlargement, sulcus widening, arachnoid cyst and cisterna magna in the study group were 51.1%, 24.4%, 31.1% and 20.0% respectively, which were significantly higher than 5.5%, 2.5%, 2.5% and 2.5% respectively in the control group ( χ2 = 21.688, 8.411, 11.928, 4.675, all P < 0.05). The recurrence rate of paranoid schizophrenia in the study group was 22.2% (10/45). The CT value of the left and right frontal lobe in patients with recurrent paranoid schizophrenia was (32.1 ± 1.7) HU and (32.5 ± 1.6) HU respectively, which was significantly lower than (35.0 ± 1.9) HU and (34.9 ± 1.7) HU in patients without recurrent paranoid schizophrenia ( t = 4.348 and 3.985, both P < 0.001). Conclusion:Patients with first-episode paranoid schizophrenia have brain structural abnormalities, as manifested by ventricular enlargement, sulcus widening, arachnoid cyst, and cisterna magna. CT imaging features are of great value in the diagnosis of first-episode paranoid schizophrenia. It deserves wide popularization and has a great innovation value.

Objective:To investigate the correlation between endothelial dysfunction and cardiomyocyte apoptosis during myocardial ischemia-reperfusion.Methods:A total of 63 male rats were selected to establish the rat model of myocardial ischemia-reperfusion by the ligation of the left anterior descending(LAD)coronary artery to simulate myocardial ischemia.Rats were divided into the control group and group Ⅰb, group Ⅰa, group Ⅱb, group Ⅱa, group Ⅲb and group Ⅲa.Control rats were treated only with LAD threading without ligation.In observation group, at 30, 90, 120 min after LAD ligation(marked as Ⅰ, Ⅱ, Ⅲ group respectively), loosen the ligation to simulate ischemia-reperfusion.In the observation group, captopril sublingual injection of 0.25 mg/kg before ligation were marked as group b, and as group a with no captopril injection.The circulating endothelial cells(CEC), endothelin(ET), nitric oxide(NO)and the apoptosis rate of cardiomyocytes in each group were measured.Results:The CEC and ET levels showed a continuous upward trend, and a NO level showed a continuous downward trend from group Ⅰa to Ⅱa to Ⅲa as compared with the control group( P<0.05). After using preventive intervention of captopril, the CEC and ET levels were lower and NO levels were higher in group Ⅱb and Ⅲb than in group Ⅱa and Ⅲa, respectively( P<0.05). The apoptotic rate of cardiomyocytes was higher in group Ⅰa than in the control group, and the apoptotic rate from high to low were from group Ⅲa[(235.71±40.25)%]to group Ⅱa[(197.28±43.56)%]to group Ⅰa[(138.55±32.87)%]and to the control group[(5.81±2.02)%]( P<0.05). The apoptotic rate of cardiomyocytes was lower in group Ⅱb[(125.67±26.51)%]and Ⅲb[(124.91±33.28)%]than in group Ⅱa and Ⅲa, respectively( P<0.05). Conclusions:The ischemia-reperfusion can cause endothelial dysfunction and the apoptosis of cardiomyocytes, and there is a close relationship between the degree of this lesions and the duration of ischemia-reperfusion.While, the appropriate application of angiotensin converting enzyme inhibitor can inhibit the damage of cardiomyocytes to a some extent.

Objective:To explore the application of linkage teaching model between hospitals and colleges based on integration of theory and practice in the course of pediatric nursing skills.Methods:Two undergraduate classes of pediatric nursing in a college in 2017 were selected as the experimental group and the control group by random sampling. The experimental group adopted the combined teaching method of colleges and hospitals based on the integration of truth and practice, while the control group adopted the traditional teaching method.
