【摘要】目的:探討局部亞低溫聯合糖皮質激素對急性睪丸扭轉復位后睪丸抗氧化能力與精子活力的影響。方法:選擇2010年1月至2015年3月我院收治的的急性睪丸扭轉者80例,按照隨機數字法分為兩組,各40例,對照組在患者入院后開始口服醋酸地塞米松片,觀察組在對照組基礎上聯合使用局部亞低溫處理,比較兩組預后SOD、MDA及總抗氧化能力、干預前后兩組NO含量及NOS活性,并統計兩組干預后精液常規及精子DNA碎片(DFI)指數。結果:干預后,觀察組SOD顯著高于對照組(P<0.05),而MDA則顯著低于對照組(P<0.05),總抗氧化能力以顯著高于對照組(P<0.05),干預后觀察組NO含量及NOS活性顯著低于干預前及干預后對照組(P<0.05),干預后觀察組精液中精子密度、精子活動率及精子活力均顯著高于對照組(P<0.05),且精子DNA碎片顯著少于對照組(P<0.05)。結論:對于急性睪丸扭轉者實施局部亞低溫聯合糖皮質激素處理,能顯著提高睪丸抗氧化能力,減輕脂質過氧化反應等缺血缺氧再灌注損傷,減少精子破壞,提高精子活力。

Effect of local mild hypothermia joint sugar temperament hormone on the testicular antioxidant capacity and sperm motility after reset of acute testicular torsionZHU Jiang, LI Yingyi, ZHANG Hui. Department of Urology, Baoji Peoples Hospital, Baoji 721000, Shaanxi, China
【Abstract】Objectives: To investigate the effect of local mild hypothermia joint sugar temperament hormone on the testicular antioxidant capacity and sperm motility after reset of acute testicular torsion. Methods: 80 patients with acute testicular torsion from January 2010 to March 2015 in our hospital were selected and randomized into two groups, each of 40 cases. The control group orally took dexamethasone acetate tablets, and the observation group received local mild hypothermia on its basis. The SOD, MDA and total antioxidant capacity, NO content and NOS activity before and after the intervention were compared to summarize the semen and sperm DNA fragmentation (DFI) index. Results: After the intervention, SOD in the observation group was significantly higher than control group (P<0.05); MDA was significantly lower than control group (P<0.05); total antioxidant capacity was significantly higher control group (P<0.05). After intervention, the NO content and NOS activity was significantly lower than pre-intervention in observation group and otherwise in control group (P<0.05). After intervention, the semen sperm concentration, sperm motility and sperm motility in observation group was significantly higher than control group (P<0.05), while sperm DNA fragmentation was significantly less than control group (P<0.05). Conclusions: Local mild hypothermia joint sugar temperament hormone can significantly improve the testicular antioxidant capacity and reduce the lipid peroxidation and other hypoxia-ischemia-reperfusion injury, thusly reducing sperm damage and improving sperm motility.

睪丸扭轉主要是因為精索發生扭轉導致,其可發生于任何年齡階段,其中急診科收治的超過25%陰囊方面急診為睪丸扭轉,如未能得到及時救治,需要切除睪丸的比例甚至超過50%[1]。其好發于新生兒期及青春期者,占青春期睪丸急診的50%以上比例,本病早期極易誤診,已經成為中青年尤其是青春期男性失去睪丸的最主要原因,進而導致男性不育癥的發生。臨床經驗證實[2],對于懷疑睪丸扭轉者甚至對于不能排除診斷者,應及時手術治療,以最大限度減少睪丸缺血缺氧時間,提高患者預后。盡管對于擬者已經明確盡快實施手術治療的價值,但部分患者入院后因主觀猶豫等,未能及時簽署手術和麻醉同意書,以及重要的術前檢查,如超聲、凝血常規、心電圖等亦需要一定時間,為更好的挽救患者病變睪丸,提高治療效果,臨床急需一種在本階段內更好的減少睪丸缺血缺氧的方法[3]。……
