Objective To evaluate the feasibility of endovascular repair for retrograde type A aortic dissection.Method 35 patients of retrograde type A aortic dissection admitted to Peking University People's Hospital from December 2001 to March 2014 were treated with endovascular repair.There were 33 males and 2 females with mean age of 46 ± 9 years.29 were on acute stage,2 on subacute stage and 4 on chronic stage.The entry tear was in the descending thoracic aorta in 32 cases,between the left subclavian artery and the left common carotid artery in one,and between the left common carotid artery and the innominate artery in two.Results Entry closure was achieved in all patients with a covered stent.2 patients died in 30 days postoperatively (5.7％).1 patient with two chimney developed acute renal artery embolized which was infused by false lumin (2.9％).One patient developed transient paraparesis after graft deployment(2.9％).During the follow-up period,the aortic remodeling is perfect,no entry tear was noted in the ascending thoracic aorta.All the endografts for preserving supra-aortic branches were patent.Conclusions The endovascular repair for retrograde type A aortic dissection is feasible and effective.

Objective To explore the effects of walking in water on surface electromyography (sEMG) of lower limbs and neural func-tion in spinal cord injury (SCI) patients. Methods From June, 2014 to May, 2016, 42 patients with incomplete thoracolumbar SCI were di-vided into control group (n=21) and experimental group (n=21) randomly. All the patients accepted routine rehabilitation, while the experi-mental group accepted extra walking in water. Average electromyography (AEMG) of quadriceps femoris and tibialis anterior muscles was measured, and the motor and sense function was assessed with American Spinal Injury Association (ASIA) Classification before and six weeks after treatment. Results The AEMG (t>5.763, P<0.01) and the scores of motor and sense (t>10.871, P<0.001) increased in both groups after treatment, and increased more in the experimental group than in the control group (t>4.036, P<0.01). Conclusion Walking in water could further improve lower limbs muscle strength and neural function in patients with incomplete thoracolumbar SCI.

OBJECTIVE To investigate deep fungal hospital infection and methods of its decreasing. METHODS Case histories of near 3 years of hospitalized patients from Jan 2002 to Dec 2004 were analyzed according to Diagnosis Standard of Nosocomical Infection under the items,such as the patients,age,underlying disease,sample,strain,and species distribution. RESULTS There were 360 fungus strains belonged to 15 species in all samples;the patients age was 14-94 with 20 kinds of various underlying diseases;the fungi included Candida albicans,and C.tropicalis,accounted for 61.1% and 17.2%,respectively;the samples were sputum,urine,vaginal secretion,BLA,throat swab and pus,which were 42.2%,21.1%,13.9%,8.4%,5.8%,and 3.6%,respectively;the respiratory department,ICU,and urology department were mainly involved. CONCLUSIONS To prevent fungal infection, measures such as hospital′s environment and management including reasonable use of antibiotics play a great role in monitoring hospital fungal infection and its epidemiology.

Objective To determine the renal effects of chronic exercise training and enalapril in uninephrectomized anti-Thy-1 nephritis Wistar rats (Thy-1-Crf). Methods 5-week-old Wistar rats were subjected to uninephrectomy. Anti-Thy-1 nephritis was induced by injecting 200 μg/kg OX-7 intravenously once a week for four times. They were divided into 3 groups: non exercise; moderate exercise with treadmill running(20 m/min, 0 grade-incline for 60 min); moderate exercise with an angiotensin converting enzyme(ACE) inhibitors, enalapril (2 mg/kg/day i.p.) for 8 weeks.Results Exercise did not suppress the increase in proteinuria in Thy-1-Crf. However, enalapril significantly decreased systolic blood pressure(SBP), urinary protein excretion(UpE), and index of glomerular sclerosis (IGS) in Thy-1-Crf. Conclusion The renal protective effects of moderate exercise in models of renal failure differ depending on the etiology of renal failure. It also suggests that enalapril can widen the acceptable range of exercise intensity in Thy-1-Crf.

Objective To investigate the safety, feasibility and results of laparoscopic assisted distal radical gastrectomy for gastric cancer. Methods Twenty-three cases of gastric cancer were subjected to laparoscopic assisted distal radical gastrectomy, D_(1+α)/D_(1+β) lymphadenectomy on 3 cases and D_2 lymphadenectomy on 20 cases. All cases received Billroth I reconstruction. Results Laparoscopic assisted distal radical gastrectomy was carried out in all cases successfully. The mean operative time was (205 ±38 )min, mean blood loss was (105 ± 66) ml and mean number of lymph nodes dissected was 19.7 ± 6.2 each case. The mean postoperative time of recovery of bowel function was (3.5 ±1.2) d,mean postoperative time of liquid intake was (4.9 ±0.9) d and mean hospitalization was (10.2 ± 2.7) d. No postoperative death or anastomotic fistula was found. Postoperative upper gastrointestinal bleeding occurred in 1 case and was cured by conservative treatment. Follow-up for 1-12 months revealed no recurrence or metastasis. Conclusions Laparoscopic assisted distal radical gastrectomy is a safe and feasible procedure with satisfactory short-term outcomes.Moreover,the short-term outcomes may be improved if the patients are treated under the notion of fast track surgery.
