RESUMO
【Objective】 To explore the effects of sexual function-preserving 450 nm blue laser vaporization of the prostate on the postoperative sexual function of patients with benign prostatic hyperplasia (BPH), and to evaluate the clinical efficacy, safety and feasibility of this procedure. 【Methods】 The clinical data of 20 BPH patients treated in our department during Jan. and Mar.2023 were analyzed. The International Prostate Symptom Score (IPSS), Quality of Life Scale (QoL) score, maximum urinary flow rate (Qmax), residual urine volume (PVR) and International Index of Erectile Function (IIEF-5) data were compared before and after the operation. The operation time, postoperative catheter indwelling time, and hospital stay were recorded. The ejaculation status 2 months after operation was followed up. 【Results】 All 20 patients completed the operation successfully. The operation time was (13.41±4.30) min, catheter indwelling time (1.2±0.4) d, and hospital stay (3.0±0.6) d. The IPSS, QoL, PVR and Qmax data 1 month after operation were significantly improved compared with those before operation (P0.05). 【Conclusion】 The modified 450 nm blue laser vaporization of the prostate can improve the urination symptoms of BPH patients while retaining sexual function. It is a safe and feasible technique for BPH patients who have sexual needs, and provides an alternative surgical approach for those looking to preserve sexual function.
RESUMO
Objective:To investigate the influence of metastasis suppressor gene KAI1 on the proliferation,invasion and metastasis of endometrial carcinoma cell line AN3CA and HEC-1-B.Methods:The KAI1 cDNA was transfected into human endometrial carcinoma cells AN3CA and HEC-1-B via Lipofectamine 2000.The expression of KAI1 protein was ex- amined by Western blotting and flow cytometry before and after transfection.The proliferation ability of AN3CA and HEC- 1-B cells was observed by MTT assay and anchorage-independent growth assay.The changes of cell invasive ability were studied by transwell assays.Results:Stable expression of KAI1 protein was observed in AN3CA and HEC-1-B cells and on their surface after transfection with pcDNA3-KAI1 plasmid.Cells transfected with blank plasmid formed more colonies and had a larger size,with the colony forming rates being(54.2?3.1)% for AN3CA cells and(52.7?4.3)% for HEC- 1- B cells;the doubling time of AN3CA and HEC-1-B cells were 21.3 h and 20.1 h,respectively.Cells transfected with pcDNA3-KAI1 formed less colonies and had a smaller size,with the colony forming rates being(37.4?5.1)% for AN3CA cells and(32.1?3.7)% for HEC-1-B cells;the doubling time of AN3CA and HEC-1-B cells were 43.7h and 45.2 h,respectively.The cell proliferation abilities and colony-forming ability were significantly different between the two groups(P
RESUMO
<p><b>OBJECTIVE</b>To investigate the difference of anticytomegaloviral activity of three kinds of traditional Chinese medicines which are the injections of Jinye Baidu, Radix Isatidis and Indigowoa in vitro.</p><p><b>METHOD</b>The inhibitory activity of three traditional Chinese medicines against human cytomeglovirus (HCMV AD169) infected human embryo lung fibroblasts (HELF) was observed by cytopathic effect method (CPE) and MTT method in vitro. According their value of A, anticytomegaloviral activity has evaluated.</p><p><b>RESULT</b>Experimental study in vitro showed that the 50% toxicity dose (TD50) of Jinye Detoxifying, Radix Isatidis root and Indigowoa were 20, 10.23, 20.23 g x L(-1) respectively; the 50% inhibitory concertration (IC50) were 5.65, 3, 5.71 g x L(-1) respectively; the therapeutic index (TI) were 3.54, 3.41 and 3.54 respectively. It suggested that three traditional Chinese medicines had anticytomeglovirus activity and their effect increased with their concentration.</p><p><b>CONCLUSION</b>Three traditional Chinese medicines of the parenteral solution of Jinye Detoxifying, Radix Isatidis root and Indigowoa have antiviral activity when they are diluted in 1:200. They are safe and valuable drug for inhibiting cytomeglovirus infection.</p>
