OBJECTIVETo investigate the clinical effect of steroids on reducing postoperative edema in rhinoplasty.

METHODSCochrane, Medline data, Pubmed date, were searched and updated on October 2013. Randomized controlled trials(RCTS) studies were included to assess the efficacy of steroids on decreasing postoperative edema after rhinoplasty. The methodological quality of the included studies was evaluated, and date analyses were performed using the Cochrane Collaboration's software RevMan 5.2.

RESULTSA total of 4 RCTS involved 172 patients with rhinoplasty, including 87 patients in the experimental group( steroid) and 85 paitents in control group (placebo). Meta analysis results showed the edema in experimental group was significantly less than that in the control group on postoperative day 1 and 3 (P < 0.01), while the difference was not significant on postoperative day 7 (P = 0.19).

CONCLUSIONSPerioperative application of steroid in rhinoplasty can significantly reduce periorbital edema in the first postoperative day. The edema can completely be relieved after application of steroid for 3 days. It is a safe and effective way to reduce the postoperative edema.

We isolated a high efficient antifungal strain A02 from forest soil in a suburb of Beijing. The result of polyphasic taxonomy confirmed that strain A02 belongs to Streptomyces lydicus. The fermented broth of the strain presented a stable and strong inhibiting activity against many plant pathogenic fungi. The purpose of this study was to ascertain the substance base of the antifungal activity of strain A02. We extracted the antifungal metabolite of A02 by using column chromatography with X-5 macroporous resin and 100-200 mesh silica gel respectively, and then purified it by LC-9101 recycling preparative HPLC with a SP-120-15 column (JAIGEL-ODS-AP). An active compound with purity over 99.845% was finally obtained. The chemical structure of the active compound was determined with spectroscopy methods, including ultraviolet spectrometry, infrared spectrometry, high resolution mass spectrometry and nuclear magnetic resonance. According to the analysis results, we identified the active compound as a tetraene macrolide antibiotic with the molecular weight of 665, the molecular formula C33H47No3 and the same chemical structure as natamycin. Our research revealed a new biosynthetic function for S. lydicus to produce natamycin, and an expanding application field for natamycin to be used for the control of fungal plant diseases.

OBJECTIVETo evaluate the clinical outcomes of ileal D-pouch anal anastomosis in the treatment of ulcerative colitis (UC) and familial adenomatous polyposis (FAP).

METHODSClinical and follow-up data of 6 UC patients and 5 FAP patients undergoing proctocolectomy and D-ileum pouch anal anastomosis between October 2014 and March 2015 were retrospectively analyzed. End-to-side anastomosis was firstly performed in ileal cutting end and ileum, then side-to-side anastomosis was operated in closing amphi-loop to construct the D-ileum pouch.

RESULTSThe mean age of the patients was 42 years (range 18 to 61 years), 5 patients were female. The duration of surgery was (225±23) min, the operation time to D-ileum pouch was (18±4) min, the volume of D-ileum pouch was (175±15) ml, the blood loss was (110±30) ml. There was no procedure-related death, however rectum perforation occurred in 1 male UC patient during operation. The postoperative hospital stay was 8 to 11 days (mean 8.5 days). The follow-up period was 2 to 7 months (median 3 months). One female FAP patient suffered from anal anastomosis vagina fistula 21 days after operation. No pouch-related fistula, anastomosis or input loop stricture fecal incontinence, and severe pouchitis were recorded. The defecation frequency was 4 to 6 times per day (UC) and 3 to 5 times per day (FAP) 6 months after operation. No night-time fecal leakage was complained in those patients. Wexner incontinence score was 3±2 and GQLI was 114±11 one month after operation. Clinical outcome in the first month was excellent in 10 patients and good in 1 patient.

CONCLUSIONSAfter total colorectal resection for UC and FAP patients, application of D-ileum pouch can clear ileal stump of pouch and avoid the pouch-associated complications effectively.

Objective:To investigate the efficacy of intravenous infusion of tranexamic acid(TXA)on perioperative blood loss in geriatric patients with hip fracture.Methods:In this retrospective study, 54 out of 95 patients with hip fracture aged from 65 years to 100 years, treated at the Department of Trauma and Osteology, West China Hospital of Sichuan University from June 2020 to June 2021 were finally enrolled.Their clinical data were collected.All patients underwent closed reduction PFNA surgery.They were divided into three groups: (1)Control group(n=18): intravenous infusion of normal saline at 30 min before surgery; (2)Single dose group(n=18): TXA(25 mg/kg)was intravenously injected at 30min before surgery; (3)multiple dose group(n=18): 25 mg/kg of TXA was intravenously injected at 30 min before surgery and 15 mg/kg injected again at 3 h and 6 h after surgery.Total blood loss and the incidence of postoperative deep venous thrombosis among 3 group patients were compared.Results:There were no statistically significant differences in gender, age, preoperative platelets, preoperative activated partial thrombin time and preoperative prothrombin time among control group, single dose group and multiple dose group(all P>0.05). Perioperative blood loss was estimated to be 620(330, 1080)ml, 380(270, 490)ml and 520(190, 750)ml in the control group, single dose group and multiple dose group, respectively, with statistical significance( H=8.666, P<0.05). Total blood loss in single dose group was less than in both control( P<0.05, with statistical significance)and in multiple groups( P>0.05, without statistical significance), and total blood loss in multiple dose group was lower than in control( P>0.05, without statistical significance), and higher than in single dose group( P>0.05, without statistical significance). Color ultrasonography was performed on the 1 st and 7 th day after surgery in 3 groups, and no deep venous thrombosis or pulmonary embolism was found in all groups. Conclusions:Intravenous infusion of TXA at half an hour before surgery can effectively reduce the total peri-operative blood loss without increasing the risk of thrombosis.A multiple preoperative intravenous drip of TXA should be cautious as compared with a single preoperative intravenous drip of TXA.

OBJECTIVETo explore the efficacy of partial resection of puborectalis combined with mutilation of internal anal sphincter(IAS) in the treatment of puborectalis syndrome with high anal pressure.

METHODSTwenty-five cases of puborectalis syndrome with high anal resting pressure in the preoperative examination received the operation of partial resection of puborectalis combined with mutilation of IAS in Zhongnan Hospital of Wuhan University between January 2013 and May 2015. The position of puborectalis was confirmed by touching with the exposure under the transfixion device, and a transverse incision was made by electrotome between 3 and 5 o'clock direction of puborectalis, then partial puborectalis was lifted by vessel clamp at 5 o'clock direction, and about 0.5 cm of muscular tissue was resected. Between 8 to 10 o'clock direction of anal tube, about 1 cm length of transverse incision was made by electrotome, then partial IAS was lifted by vessel clamp and cut off. Preoperative and postoperative 3-month anorectal manometry and defecography were carried out. Wexner constipation score and Cleveland Clinic incontinence score were implemented before surgery and 3, 6, 12 months after operation. This study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-ORB-16007695).

RESULTSOf the 25 cases, 18 were male and 7 were female, the average age was 55 years old and the average course of disease was 9 years. Compared with pre-operation, the postoperative 3-month anal resting pressure and maximal squeeze pressure were significantly decreased [(53.56±9.05) mmHg vs. (92.44±7.06) mmHg, (142.80±20.35) mmHg vs. (210.88±20.56) mmHg, respectively, both P=0.000]; anorectal angulation at resting state and forced defecation state increased significantly [(102.32±4.96)degree vs. (95.88±4.01)degree, (117.88±5.95)degree vs. (89.52±3.25)degree, respectively, both P=0.000]. Wexner constipation score of postoperative 3-month, 6-month, 12-month (8.28±3.91, 7.40±3.64 and 8.04±4.74) was significantly lower than the preoperative score (16.00±3.69, all P<0.05), while the score was not significantly different among 3 time points after operation (P>0.05). Cleveland Clinic incontinence score was 0 at postoperative 6 and 12 months, and revealed 20 cases were effective among all the surgical patients(80%).

CONCLUSIONPartial resection of puborectalis combined with mutilation of internal anal sphincter can effectively reduce anal pressure and improve symptoms of outlet obstruction, which is an effective method in the treatment of puborectalis syndrome with high anal pressure.
