1.Fecal incontinence in adults:diagnose and treatment
Journal of Clinical Surgery 2018;26(4):313-316
This paper delineate the definition,etiology and treatment of fecal incontinence,Initial management of fecal incontinence consists of supportive care and medical therapy.If patients fail to re-spond to initial management,such patients should undergo additional evaluation(such as anorectal manom-etry,endorectal ultrasound and magnetic resonance imaging)to detect functional and structural abnormali-ties causing fecal incontinence and to guide subsequent management.For patients who fail to respond to initial management,options include biofeedback,injectable anal bulking agent,sacral nerve stimulation, and anal sphincteroplasty.Dynamic graciloplasty and artificial anal sphincter devices are associated with significant morbidity and should therefore only be used to treat refractory fecal incontinence.Fecal diver-sion with a colostomy should be reserved for patients with intractable symptoms who are not candidates for any other therapy,or in whom other treatments have failed.

Objective: To investigate the therapeutic effects of compound Kushen Tang and its relevant mechanism in TNBS-in-duced ulcerative colitis ( UC) rats. Methods:UC was induced by TNBS in rats. After compound Kushen Tang was given orally, the levels of MDA, iNOS, and NO and the activity of MPO, SOD, and GSH-Px were measured. The general condition of rats and colon tissue morphology were observed. Results:The levels of MDA (P<0. 05), iNOS (P<0. 01) and NO (P<0. 01) and the activity of MPO (P<0. 01) in tissues of UC rats were significantly higher than the control group. The activity of SOD (P<0. 01) and GSH-Px (P<0. 05) were significantly lower than those in the control group. After the treatment with high doses of compound Kushen Tang, the levels of MPO (P<0. 01), MDA (P<0. 05), iNOS (P<0. 05) and NO (P<0. 01) were significantly decreased, and the activity of SOD (P<0. 01) and GSH-Px (P<0. 05) significantly increased. The therapeutic effect was dose-dependent and the general con-dition of rats and colon tissue morphology were also significantly improved. Conclusion:Compound Kushen Tang is considered as a no-vel therapeutic alternatives for the treatment of UC, which can reduce coloni inflammatory injury and ameliorate the colitis.

Given that increased thermogenesis in white adipose tissue, also known as browning, promotes energy expenditure, significant efforts have been invested to determine the molecular factors involved in this process. Here we show that HOXC10, a homeobox domain-containing transcription factor expressed in subcutaneous white adipose tissue, is a suppressor of genes involved in browning white adipose tissue. Ectopic expression of HOXC10 in adipocytes suppresses brown fat genes, whereas the depletion of HOXC10 in adipocytes and myoblasts increases the expression of brown fat genes. The protein level of HOXC10 inversely correlates with brown fat genes in subcutaneous white adipose tissue of cold-exposed mice. Expression of HOXC10 in mice suppresses cold-induced browning in subcutaneous white adipose tissue and abolishes the beneficial effect of cold exposure on glucose clearance. HOXC10 exerts its effect, at least in part, by suppressing PRDM16 expression. The results support that HOXC10 is a key negative regulator of the process of browning in white adipose tissue.

Objective To summarize the magnetic resonance imaging (MRI) features of the persistcnt perineal sinus (PPS).Methods The retrospective and descriptive study was conducted.The clinical data of 7 patients with PPS who were admitted to the Nanjing University of Traditional Chinese Medicine between July 2010 and January 2017 were collected.Patients received horizontal,anteroposterior axes and coronal scanning of MRI after abdominoperineal resection (APR) of rectal cancer.Two physicians read collectively films and then achieved consistent results if there was a disputed result.Observation indicators:(1) MRI features;(2) treatment and follow-up situations.Patients underwent resection of PPS according to results of MRI examination,and then regular pathological examination.Follow-up using telephone interview was performed to detect sinus recurrence and reoperation up to April 2017.Results (1) MRI features:① Lesion location:lesions of PPS in 7 patients were located at the presacral areas,top side was up to the third sacral plane,and lower side extended down to the pubic area.② Morphology and signal:sinus tract of 7 patients showed irregular flaky and tubular abnormal signals;fibrotic sinus tract wall showed low signals in T1 weighted imaging (T1WI) and T2WI;contents of sinus tract in 7 patients showed low signal in T1WI and high signals in T2WI and T2WI-fat suppression (T2WI-FS).Of 7 patients,uniform signal and mixed signal were respectively detected in 2 and 5 patients.③ Branches and cystic spaces:1 patient had a branch at the tip of the coccyx,extending to the rear of the sacral vertebra.The top of sinus tract in 4 patients enlarged to form a cavity.④ Signs of infection:signs of infection in 3 patients included blurred and exuded fat gaps around the sinus tract,unclear and partially adhesion with pelvic organ;the pelvic floor muscles in 1 patient were thickened and swollen,with a high signal in T2WI-FS;flaky fluid shadows in 2 patients were seen in the posterior sinus,with a high signal in T2WI-FS,showing a tissue edema of anterior sacrum.⑤ Enhancement features:result of MRI examination of 1 patient showed mild and heterogeneous enhancement of sinus.(2) Treatment and follow-up situations:among 7 patients undergoing sinus resection,2 received curettage of superior sinus due to high location,and 5 received successfully operation.All patients underwent postoperatively regular antibiotic therapy.The healing time was 14-78 days,with an average time of 42 days.The postoperative pathological examination showed different degrees of inflammatory cell infiltration.Seven patients were followed up for 2-74 months,with an average time of 40 months.Of 7 patients,sinus in 6 patients was healed,1 had recurrence of sinus and didn't receive therapy.Seven patients didn't undergo debridement or transposition of skin flap again.Conclusion The MRI imaging features of PPS includes flaky and tubular abnormal signal in the the anterior sacrum,low signal in T1WI,high signals in T2WI and T2WI-FS,and the enhanced scanning of sinus duet shows mild and heterogeneous enhancement.
