摘要:目的: 隨機對照研究、評估生物反饋訓練治療慢性功能性便秘的療效。 方法 : 60例慢性功能性便秘患者,隨機分為治療組30例和對照組30例。治療組接受1個療程(5周)生物反饋訓練治療(10次為一個療程、一次30～45分鐘、每周2次)。對照組患者接受聚乙二醇4000 10g BID 口服,療程5周。治療前后作便秘癥狀評分、結腸通過試驗檢測、直腸肛門壓力檢測。 結果 : 生物反饋訓練和聚乙二醇4000均可使多數慢性功能性便秘患者的大便次數、大便性狀及伴隨癥狀恢復正常或緩解,總有效率分別為667%和80%(P ＞005)。生物反饋訓練和聚乙二醇4000口服治療后,結腸通過試驗72小時標志物排出率分別為75%及73%,均較治療前明顯增加。生物反饋訓練治療后力排時肛門壓明顯下降。 結論 : 生物反饋訓練對出口梗阻型、慢傳輸型便秘均有效,是一種有效的、新興的治療慢性功能性便秘的方法,可作為功能性便秘的一線治療方法。Abstract: Objective: To assess the clinic effect of biofeedback therapy for functional constipation. Methods : Sixty cases of chronic functional constipation were randomly divided into treatment group (30 cases) and control group (30 cases). Cases in the treatment group were exposed to biofeedback for a fiveweeklong treatment course—individual treatment lasted for 3045 minutes and twice per week. Patients in the control group received PEG 4000 10g BID for five weeks. Data from constipation symptom score, colonic transit test, and anorectal manometry were done and compared before and after two kinds of treatments. Results : Biofeedback training and PEG 4000 could restore the stoolfrequency, stool characteristics and accompanying symptoms to normal or mitigation of the majority of patients with chronic functional constipation, with the total effective rates being 667% and 80% (P gt;005), respectively. After biofeedback training and PGE 4000 treatment, the discharge rate of 72hour markers of colonic transit test significantly increased to 75% and 73%, respectively. Additionally, anorectal pressure decreased dramatically after biofeedback training. Conclusion : Biofeedback training would play a positive role in outlet obstruction and slow transit constipation. Thus, it could be an effective firstline treatment of chronic functional constipation.
Objective To systematically review the effect of bariatric surgery for male’s erectile function. Methods We electronically searched databases including PubMed, EMbase, The Cochrane Library (Issue 5, 2016), CNKI, VIP and WanFang Data from inception to May 30th 2016, to collect randomized controlled trials and before-after studies about bariatric surgery therapies for erectile function in obese male. Two reviewers independently screened literature, extracted data, and assessed the methodological quality of included studies. Then RevMan 5.3 software was used for meta-analysis. Results A total of 7 before-after studies involving 270 patients were included. The results of meta-analysis showed that: compared with before treatment, bariatric surgery could significantly improve 1-year erectile function score (MD=5.05, 95%CI 3.52 to 6.59, P < 0.000?01), 1-year sexual desire score (MD=0.99, 95%CI 0.47 to 1.51, P=0.000?2), 1-year contact satisfaction score (MD=2.70, 95%CI 0.21 to 5.19, P=0.004) and 1-year total satisfaction score (MD=1.68, 95%CI 0.27 to 3.09, P=0.002), but there was no significant difference in orgasm function score (MD= –0.21, 95%CI –0.74 to 0.33, P=0.45) between before and after treatment. Conclusion Bariatric surgery is effective in improving the erectile function, sexual desire and sexual satisfaction in morbidly obese male. Due to the limited quality and quantity of the included studies, the above conclusion needs to be verified by more large-scale high-quality studies.

Methods Twenty-one patients with prostate cancer had undergone radical prostatectomy during August 2001 to January 2010, in which two patients were operated through extraperitoneal laparoscope. Dorsal vein complex was sewed and ligated at early stage of surgery and prostate apex along with urethra were appropriately handled in all patients. By a serial measures consisting of protection for continence nerve and striated urethral sphincter, the function of urinary continence was managed to be spared in twenty-one patients, erectile function was managed to be spared through reservation of neurovascular bundle in seventeen patients (Bilateral neurovascular bundles were reserved in twelve patients, unilateral neurovascular bundle was reserved in five patients). Results All surgeries were successful without severe perioperative complications. The catheters were removed fourteen days after surgery in all patients, and it was observed that micturition was fluent in twenty-one patients. Functional recovery of urinary continence occurred within three months after surgery in six patients and twleve months in thirteen patients, continuous mild-moderate incontinece occurred in two patients. Erectile function was normal before surgery and neurovascular bundle was reserved during surgery in seventeen patients. The recovery of erectile function occurred within three months after surgery in two patients and twelve months in eight patients, erectile function was impaired in four patients, erectile dysfunction occurred in three patients, pathological diagnosis indicated prostate adenocarcinoma in all cases, while seminal vesicle and bladder neck were not invaded and bilateral pelvic lymph nodes were not metastasized, moreover, the pathological diagnosis of resected edge of posterior urethra was positive in one patient. One patient of bio-chemical recurrence occurred respectively within six months, twenty-four months and fifty-four months after surgery. Conclusion During radical prostatectomy for prostate cancer, delicately anatomizing and appropriate surgical technique could effectively protect erectile function and urinary continence and consequently achieve radical resection of tumor at the same time.

Objective To study the relationship between autonomic nerve preservation and sexual and urinary functions after total mesorectal excision in patients with cancer of the lower rectum, and to explore improved nursing methods for these patients. Methods Eligible patients with cancer of the lower rectum were non-randomly assigned to either a control group (n=278)or an autonomic nerve-preserving group （n=263）. The recovery time of micturition desire, catherization time, lower urinary tract infection rate, residual urine, severity of urinary disorders and sexual disorders were observed. Results The recovery time of micturition desire, catherization time, lower urinary tract infection rate, residual urine, severity of urinary disorders and sexual disorders were lower in the autonomic nerve-preserving group than in the control group. (Plt;0.05) . Conclusion Autonomic nerve preservation radical resection leads to better maintenance of urinary and sexual functions for patients with cancer of the lower rectum. Nursing should be focused on the prevention of urinary tract complications and the rehabilitation of sexual and urinary functions.
ObjectiveTo systematically evaluate the effects of weight-loss interventions on hormone levels and sexual function in patients with obesity. MethodsThis review was conducted in accordance with PRISMA guidelines. A systematic search of PubMed, Embase, and other databases was performed for studies published within the past decade that investigated the effects of bariatric surgery, glucagon-like peptide 1 (GLP-1) receptor agonists, and lifestyle interventions on sex hormones and sexual function. ResultsBariatric surgery (e.g., sleeve gastrectomy, gastric bypass) demonstrated the most pronounced improvements in hormonal balance and sexual function. In males, total testosterone levels doubled postoperatively, with marked increase in erectile function score. In females with polycystic ovary syndrome, androgen levels were reduced by 50%, with significant amelioration in the female sexual function index. GLP-1 receptor agonists (e.g., semaglutide, liraglutide) partially improved sperm quality and testosterone levels, but were also associated with a higher risk of erectile dysfunction (with a hazard ratio of approximately 4.5). Lifestyle interventions (e.g., low-calorie diet, exercise) could increase sex hormone-binding globulin levels and improve sexual function score, although their efficacy remained inferior to that of surgery. ConclusionsWeight-loss interventions can alleviate hormonal imbalances and sexual dysfunction in obesity, with bariatric surgery demonstrating the most significant effects. Pharmacological and lifestyle interventions have shown variable efficacy. Future research should further investigate mechanisms underlying effects of different weight-loss modalities on sexual health.
