Objective To explore selection of the procedures in one stage urethroplasty for treatment of the coexistence of urethral strictures in anterior and posterior urethra.Methods Between January 2008 and December 2014, a total of 27 patients with coexist strictures simultaneously in anterior urethra and posterior urethra were treated in our hospital.The mean age was 38 years old (ranging 13-83 years old.Stricture etiology was secondary to lichen sclerosus in 2 patients, iatrogenic in 3 and posttraumatic in 22.The mean length of urethral stricture was 11cm (ranging 6-14cm).Two procedures for treatment of anterior urethral stricture, including augmentation of urethroplasty using penile skin flap was performed in 20 patients and augmentation of urethroplasty using lingual mucosa in 7.Three procedures for treatment of posterior urethral stricture, including non-transecting spongiosum end to end anastomosis of the two urethral ends was performed in 3 patients, end to end anastomosis of the two urethral ends was performed in 17 and substitution urethroplasty using different tissues was performed in reminder 7 patients.Of them, pedicle scrotal skin urethroplasty was performed in 2 patients and lingual mucosal graft urethroplasty in 5 patients.Results The patients were mean followed up 2.6 years (ranging 0.545.0 years) with an overall success rate of 88.9％ (24 of 27 cases).Complications developed in 3 patients (11.1％).Of the 17 patients with end to end anastomosis, urethral stricture developed respectively 4 and 6 months in 2 patients and voiding well after pedicle scrotal skin urethroplasty.Urethral pseudodiverticulum developed 9 months after pedicle penile flap urethroplasty in another patient and voiding well after urethroplasty.Urethrography showed patent urethra with adequate lumen in the remaining patients and mean urinary peak flows was 21.3 ml/s (ranging 14.2-37.9 ml/s).Conclusions Substitution urethroplasty using penile skin or oral mucosa was more good procedure for anterior urethral stricture during the treatment of the coexistence of urethral stricture in the anterior and posterior urethra.The treatment of posterior urethral stricture was based on the length of the stricture, local condition to make a choice between anastomotic urethral reconstruction and substitution urethroplasty using other tissue.

Objective To investigate the clinical efficacy of transumbilical single-incision retrograde laparoscopic cholecystectomy.Me,otis The clinical data of 979 patients with gallbladder diseases who were admitted to the Shengjing Hospital of China Medical University from May 2009 to December 2012 were retrospectively analyzed.The numbers of patients who were admitted in the year of 2009,2010,2011 and 2012 were 51,265,374,289,respectively.The preoperative preparation of transumbilical single-incision retrograde laparoscopic cholecystectomy was similar to that of traditional multi-portal laparoscopic surgery.During the operation,the umbilical incision was selected.After the body and bottom of the gallbladder was dissociated,the cystic duct of gallbladder was dissociated and straightened,which was vertical to the common bile duct.After clipping the proximal part of the cystic duct of gallbladder with 2 hem-o-lock clips,the cystic duct was cut off with the ultrasonic knife,and then the gallbladder was removed.Postoperative nursing was also similar to that of traditional laparoscopic cholecystectomy.Patients were followed up via phone call or out-patient examination till March 2013.The wound infection,incisional hernia,incisional pain,cosmetic benefits were observed.Results No patient was converted to open surgery.Twenty patients were converted to multi-portal laparoscopic cholecystectomy because of severe inflammation (3 patients in 2009,5 in 2010,5 in 2011 and 7 in 2012).The mean operation time and volume of blood loss of the 959 patients were 48.5 minutes and (27 ± 25) mL.The operation time in 2009,2010,2011 and 2012 were 51.8 minutes,49.2 minutes,48.9 minutes and 46.7 minutes.The volumes of blood loss in 2009,2010,2011 and 2012 were 35.0 mL,32.1 mL,33.8 mL and 22.9 mL,respectively.The postoperative pain was slight.Forty-seven patients were administered antalgesics (5 in 2009,12 in 2010,18 in 2011 and 12 in 2012).In the 959 patients,umbilical swelling occurred in 4 patients,and was cured by disinfection treatment.Bile duct injury occurred in 3 patients from 2010 to 2011,timely repair wad done in 2 patients,and 1 was cured by drainage.The mean time of postoperative exhuast time and duration of hospital stay were 2.2 days and 4.2 days.A total of 924 patients were followed up for 1-3 months.The scar was hidden in the navel,and no incisional hernia occurred.Conclusion Transumbilical single-incision retrograde laparoscopic cholecystectomy is safe and effective with cosmetic benefits.

Moyamoya disease (MMD) is a chronic and progressive cerebrovascular disease which is characterized by the bilateral internal carotid artery ends and (or) stenosis or occlusion of anterior cerebral artery and middle cerebral artery initial segments,compensatory proliferation of small blood vessels in the skull base and formation of abnormal vascular network.Its etiology and pathogenesis remains unclear.The present studies speculate that MMD may be a polygenic disease,inflammation,immune response,abnormal cytokine secretion,endothelial progenitor cell change and nitric oxide level change are associated with the occurrence and development of MMD.This article reviews the advances in research on the genetics and pathophysiological mechanism of MMD.

Objective: To observe the effect of double LVIS stent intussusception assisted coils embolization in treatment of intracranial blood blister-like aneurysm (BBA). Methods: Data of 45 patients with BBA and treated by stent-assisted coils embolization were retrospectively analyzed. The patients were divided into double LVIS stent group (DLS group, 18 cases) and non-double LVIS stent group (NDLS group, 27 cases) according to the disparate therapy method. The operation outcomes, perioperative complications and follow-up results were compared between groups. Results: The immediately completely embolization rate in DLS group was 72.22% (13/18), in NDLS group was 55.56% (15/27), and the perioperative complications rate in DLS group was 16.67%(3/18), in NDLS group was 25.93%(7/27) (both P>0.05). No significant difference of the immediately completely embolization rate nor of perioperative complications rate was found between 2 groups (both P>0.05). At the 3- and 6-month follow-up, no significant difference of neurological recovery outcomes post operation was found between 2 groups (both P>0.05). The aneurysm recurrence rate in DLS group was 15.38% (2/13), lower than that in NDLS group (57.89%, 11/19) at 3-month follow-up (P=0.03). No significant difference of aneurysm recurrence rate at 6-month follow-up was found between groups (0 vs 13.33%, P>0.05). Conclusion: Double LVIS stent intussusception assisted coils embolization is safe and effective for treatment of BBA, which can significantly reduce 3-month aneurysm recurrence rate.

OBJECTIVETo investigate the therapeutic effect of facial artery perforator flap for the soft tissue defects at nose, lip and cheek.

METHODSThe facial artery perforator adjacent to the defect was identified by Doppler ultrasonography. The perforator flap was designed according to the defect location, size and shape. The subcutaneous tissue around the perforator was kept as much as possible to protect the venous drainage.

RESULTSFrom Oct. 2012 to Oct.2013, 26 cases were treated with facial artery perforator flaps, with 9 cases of nasal defects, 10 cases of lip defects and 7 cases of buccal defects. The defects size ranged from 1.5 cm x 2.0 cm to 3.0 cm x 3.0 cm and the flaps size ranged from 2.0 cm x 2.5 cm to 3.5 cm x 3. 5 cm. Superficial necrosis(3mm in width) happened at the end of one flap. All the other 25 flaps survived completely. 16 cases were followed up for 3 months to 2 years with no relapse and satisfactory cosmetic and functional results were achieved.

CONCLUSIONSBoth cosmetic and functional effect can be achieved with facial artery perforator flap for defects at nose, lip and cheek.

Objective To investigate the effect of total glucosides of paeong (TGP) on the liver lipid infiltration and fibrosis in rats with non-alcoholic fatty liver disease (NAFLD) induced by fructose and high-fat diet. Methods Fructose-high-fatty induced NAFLD rat model was established. Metformin ( MET,200 mg · kg-1 ) and TGP (200,100 mg · kg-1 ) was intragastrically given to the rats in the treatment group,TGP high dose and low dose group,respectively. Normal control group and model control group was intragastrically treated with equivalent distilled water (10 mL·kg-1 ). At the fourth week after the treatment,all the rats were sacrificed and the indices such as serum fasting blood glucose(FBG),INS,insulin sensitivity index (ISI),triglycerides(TG),apelin-36,visfatin,alanine aminotransferase(ALT),aspartate aminotransferase(AST),free fatty acid (FFA),collagen Ⅲ(COLⅢ),collagen Ⅳ(COLⅣ) were determined. Hepatic content of TG was determined and the pathological changes in the liver tissues were observed under the microscope. Results As compared with the model control group,TGP effectively decreased FBG,INS,TG in serum and liver tissues,activity of ALT and AST in serum and content of FAA,Apelin, Visfatin,COLⅢ and COLⅣ,with significant differences (P<0. 05 or P<0. 01). TGP alleviated lipid infiltration and fibrosis in rat liver tissues. Conclusion TGP can inhibit effectively lipid infiltration and fibrosis of NAFLD rats,probably through improving glucolipid metabolism and antogonizing insulin resistance.

Objective To investigate the safety and clinical effect of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in the treatment of hepatocellular carcinoma (HCC) with cirrhosis.Methods The retrospective cohort study was adopted.The clinical data of 5 patients with primary HCC with cirrhosis who underwent ALPPS at the First Bethune Hospital of Jilin University between October 2014 and August 2015 were collected.The surgical plan was determined according to preoperative liver function and liver functional reserve.The patients underwent portal vein (PV) ligation and liver partition in the first staged surgery.The second staged surgery was performed when growing future live remnant (FLR) came up to the standard of safe section by rescan of computed tomography (CT) at 10,14,18 days after the first staged surgery,and hemihepatectomy and hepatic segmentectomy were applied to patients.(1) The intraoperative situations were observed,including the severity of liver cirrhosis,first staged surgery time,volume of intraoperative blood loss and FLR in the first staged surgery,interval time of surgery,growth rate of liver volume,ratio of FLR and standard liver volume (SLV),time and volume of intraoperative blood loss in the second staged surgery.(2) Pre-and postoperative biochemical indicators in the first and second staged surgeries were detected,including total bilirubin (TBil) and alanine phosphatase (ALT).(3) Postoperative situations were observed,including occurrence of complications,results of pathological examination and duration of hospital stay.(4) The follow-up using telephone reservation and outpatient examination was performed to detect tumors recurrence and metastasis and survival of patients by imaging examination and tumor marker test up to November 2015.Count data were represented as mean (range).Results (1) Intraoperative situations:of 5 patients,there were 1 patient with F3 of liver cirrhosis and 4 with F4 of liver cirrhosis.One patient was complicated with lots of peritoneal effusion,followed by acute renal failure,and didn't receive the second staged surgery.Four patients underwent successful ALPPS.The first staged surgery of 5 patients:average operation time,volume of intraoperative blood loss,FLR,interval time of surgery,growth rate of liver volume,ratio of FLR and SLV were 282 minutes (range,240-320 minutes),500 mL (range,300-700 mL),457 em3(range,338-697 cm3),15 days (range,14-18 days),58％ (range,46％-67％) and 42％ (range,32％-44％),respectively.Average operation time and volume of intraoperative blood loss in second staged surgery were 220 minutes (range,200-260 minutes) and 412 mL (range,300-600 mL).(2) Pre-and post-operative biochemical indicators:levels of TBil and ALT of 5 patients from pre-operation to postoperative day 12 in the first staged surgery were from 4.9-30.4 μmol/L to 9.8-56.1 μmol/L and from 12.9-156.1 U/L to 46.3-207.3 U/L,respectively.Levels of TBil and ALT of 4 patients from pre-operation to postoperative day 10 in the second staged surgery were from 10.1-21.2μmol/L to 6.9-38.0 μmol/L and from 30.8-55.5 U/L to 19.8-72.8 U/L,respectively.(3) Postoperative situations:there were no perioperative death and postoperative complications of liver failure and intraperitoneal infection.One patient complicated with bile leakage was cured by non-operative treatment for 30 days.Results of pathological examination:5 patients were confirmed as Ⅱ-Ⅲ stage HCC,and 4 tumors had vascular tumor thrombi and negative resection margin with tumor size of 8-13 cm.Duration of hospital stay of 5 patients was 36 days (range,28-48 days).(4) Results of follow-up:4 patients undergoing successful ALPPS were followed up for 4-12 months.One patient was emerged with a new lesion of 2 cm in left half liver at postoperative month 7,level of AFP of which was 512 μg/L before the first staged surgery reduced to normal level at postoperative month 2,and then the patient received transcatheter arterial chemoembolization (TACE) and radio frequency ablation (RFA) treatments without tumor recurrence up to postoperative month 12.No tumor recurrence and new lesions in liver were detected in other 3 patients by abdominal enhanced scan of CT,with a normal level of AFP.Conclusion ALPPS is safe and feasible for HCC with cirrhosis,with a satisfactory short-term outcome.

Objective To explore the efficacy of constructing the neourethra using a bladder anterior wall for the treatment of female total urethral stricture or atresia.Methods We retrospectively reviewed 11 female patients with total urethral stricture or oblitalition,who were underwent a procedure of reconstructive neourethra using a bladder anterior wall,from January 2009 to November 2015.Of the 11 patients,urethral stricture was associated with vesicovaginal fistula and a severe hydrocolpos in the proximal vagina because of vaginal anterior strictures or atresia in four girls.The mean age was 16 years (ranging 5-48 years) in all patients.The etiology was posttraumatic urethral injuries after pelvic fracture in 9 patients,radical urethral resection because of urethral cancer in 1 patient and congenital bladder exstrophy with an absent urethra in 1 patient.All patients underwent a procedure of neourethral construction under general anesthesia.The bladder anterior wall,which was about 2.0 to 2.5 cm in width and 4.0 ～4.5cm in length,was separated from bladder neck to middle partion of the anterior bladder wall.The bladder flap was tubularized around a 12-14 French catheter using continuous 4-0 polyglycolic acid sutures for the mucosa and interrupted sutures of 3-0 polyglycolic acid for the muscle.The tubularized flap was then flipped caudally to the site of the original external urethral meatus to form a new urethra.4 patients with severe stenosis or oblitalition of the distal vagina underwent a procedure of vaginoplasty at same time,including island vulvar flaps enlarging vaginoplasty in two girls and reconstructive vaginal orifice using the proximal enlargedvagina wall in other two girls.Results There were no serious complications postoperatively.The catheter was removed 3 ～4 weeks after the operation.7 patients were completely continent with excellent voiding,3 patients had stress incontinence.One patient experienced dysuria.And the urethroscopy in this case showed that the mucosal prolapse was present at the 12 to 3 o'clock position on the neck of the bladder,which caused urinary obstruction.Endoscopic resection of the prolapsed mucosa was performed.The patient could easily void without incontinence after the operation.The patients were followed up a median of 38 months,(ranging 6-72 months).2 patients experienced dysuria 3 and 4 months after operation,separatively.Examination showed that the mucosal prolapse was present at the position on the neck of the bladder in one patient and urethral meatal stenosis in another patient.The two patients were separatively underwent a procedure of endoscopic resection of the prolapsed mucosa and meatal urethroplasty,using vulvar flap.All of them could easily void without incontinence after the operation.Of the 3 patients with stress urinary incontinence,one underwent a procedure of TVT-O one year later,and after which continence was achieved with good voiding;the other two cases were awaiting for reoperation.Four cases of postoperative vaginal fluid disappeared with unobstructed micturition.Conclusions Female neo-urethral reconstruction using the bladder anterior wall flap was a reliable technique for the management of complete urethral stricture or obliteration.

Objective To compare the effects of two different parenteral nutrition solutions on nutritional status of premature infants,such as the early physical,serum prealbumin,retinol binding protein and albumin.Methods We collected 61 cases of premature infants in neonatal intensive care unit of the Third Military Medical University Xinqiao Hospital,which were divided into 2 groups of traditional parenteral nutrition (TTPN) and early parenteral nutrition (ETPN).Group TTPN geted 6％ paediatric compound amino acid 0.5 g/(kg·d) at24 hours after birth,daily increasing 0.25 ～0.5 g/(kg·d),up to 3.0 g/(kg·d).The 20％ long-chain fat emulsion 0.5 g/(kg ·d) was applied at 3 days after birth,daily increasing 0.25 ～ 0.5 g/(kg·d),up to 3.0 g/(kg·d).Group ETPN get 6％ paediatric compound amino acid 1 g/(kg·d) at 12 ～24 hours after birth,daily increasing 0.5 g/(kg·d),up to 3.0 ～ 0.5 g/(kg· d).The 20％ long-chain fat emulsion 0.5 ～ 1.0 g/(kg·d) was applied after 24 hours after birth,daily increasing 0.5 g/(kg· d),up to 3.0 g/(kg· d).We calculate calorie and amino acid intake of the two groups,and compared the weight,length,head circumference growth,serum prealbumin,retinol-binding protein and albumin levels of the two groups.Results The amino acid and total caloric intake of Group ETPN were significantly higher than those of Group TTPN (P ＜ 0.05).No statistical differences in the albumin,prealbumin,and retinol binding protein level of the two groups at birth (P ＞ 0.05).However,the prealbumin and retinol-binding protein level of group ETPN significantly higher than those of Group TTPN (P ＜ 0.05) at 7 days after birth.Conclusion Early parenteral nutrition in early life can effectively improve physical growth and nutrient metabolism status of premature infants.Prealbumin and retinol-binding protein are sensitive to evaluate the protein nutritional status in premature infants.
