Thirty-four patients with chronic lingual tonsillar hypertrophy were treated in our department from 1994 to 2000. There were 18 males and 16 females ranging in age from 21 to 60 years old. The clinical feature of lingual tonsillar hypertrophy usually appeared a series of pharyngeal symptoms, such as foreign-body sensation, sore throat, speech change, difficulty in swallowing, dysapnea and obstructive sleep apnea. The CO2 laser surgical lingual tonsillectomy was used for these patients. Result showed that the cure rate was 100% without any serious complications by following up 2 months to 3 years. The variety of presentations of lingual tonsillar hypertrophy and methods of surgical treament were discussed.

Objective To evaluate Ho:YAG laser in the treatment of superficial bladder tumors. Methods 30 patients with superficial bladder tumors underwent endoscopic holmium laser resection with postoperative intravesical instillation therapy.There were 25 male patients and 5 famale with an average age of 54.The growth has been single in 15 and multiple in 15.The diameter of the tumor was 0.2～3.5 cm with the pathology grade G 1～G 2 and clinical stage T 1～T 2. Results The procedure has been successful in all and cold cup biopsies of the tumor base and incisal margin were negative.The mean resection time was 18 minutes,the mean volume of bleeding was less than 15 ml and no intraoperative bladder perforation or secondary hemorrhage occurred.All patients have been followed up for 3 to 14 months with a mean of 7.5 months.One patient (3%) had out-of-field recurrence. Conclusions Ho:YAG laser resection of bladder tumor (HoLRBt) provides an useful clinical therapeutic method that has the advantages of precise resection,simple technique,as well as no serious intraoperative or delayed complications.

Objective To highlight diagnosis and treatment of primary fibroepithelial polyp of ureter. Methods 7 cases of primary fibroepithelial polyp of ureter treated from May of 1990 to July of 2002 were analyzed retrospectively.Among them ,18～56 age of year,and right side in 5 cases,left in 2 cases.The foci are in upper,middle and lower part 2,3,2 cases respectively.The diagnosis was all ascertained on pathological studies. Results Hematuria and flank pain are the usual presentation.Preoperative image will reveal the lesion but the diagnosis of fibroepithelial polyp cannot be made by radiographic means alone.Surgical intervention was undertaken in all 7 cases.The initial case has undergone unnecessary nephroureterectomy as misdiagnosis of carcinoma of ureter.Surgical exploration and polypectomy was performed in 4 cases and polypectomy with holimlaser under ureteroscopy in 2 cases.The therapeutic results were satisfactory without relapse in 3 months～11 years follow up. Conclusions The diagnosis may be established with intravenous urogram and retrograde pyelography and surgical exploration may be performed when necessary.With the advent of ureteroscopy, a new minimally invasive approach to fibroepithelial polyp of ureter was introduced.

Obiective To observe the value of speckle tracking imaging(STI)in assessing left atrial(LA) function in patients with chronic heart failure(CHF).Methods Twenty-two patients with CHF[LVEF(37.1± 10.5)%]and twenty normal controls[LVEF(61.94±10.68)%]were studied.CHF group was subdevided into patients with normal or abnormal LV filling pressure.Velocity vector imaging(Siemens Medical Solutions)was used to acquire 2-D images at parasternallong axis and apical 4-chamber views.The LA dimension and volume,LV volume and ejection fraction,ratio of mitral valve E wave and mitral annulus velocity e'E/e')were measured. LA tangential and radial velocity(Vt-As,Vr-As)and time to peak velocity(TVt-As,TVr-As)were analysed on Syngo Workplace offline.Results Vt-As and Vr-As of the CHF group were significantly smaller than those of the controls(P＜0.05),and Vr-As was even decreased in patient with elevated LV filling pressure(P＜0.05), however,TVt-AS and TVr-AS didn't show evident impairment in the CHF group(P＞0.05).Vt-As and Vr-AS were closely correlated with LVEF,EDV and ESV(P＜0.05).Vt-As was negtively correlated with LA volume (P＜0.05).Conclusions STI can quickly and accurately assess LA function,and help to recognize patients with elevated LV filling pressure,which is useful in the risk stratification,treatment evaluation and prognosis prediction of CHF patients.

Objective In order to grasp the status quo of the internship nursing students' evidence awareness in our province, to improve the teaching measures, and to promote nursing safety. Methods We delivered questionnaires to 480 nursing students who were exercising practice in some major hospitals in our province about their contemporary consciousness of evidence, the results underwent analysis. Results The results showed that the awareness of nursing evidence was very poor in the new period. Conclusions It's imperative to enhance the normative education about evidence awareness among the nursing students.

OBJECTIVE: To provide reference for patients with type I incisions about rational use of antibiotics.METHODS: Between Oct.2007 and Mar.2008,a total of 1 024 medical records of patients with type I incisions from orthopaedics,common surgery,department of gynecology in 12 hospitals of Xining area were sampled for analysis of prophylactic use of antibiotics.RESULTS: 100.0% of the type I incision patients received prophylactic antibiotics;28.4% used antibiotics without indication;16.9% used antibiotics at 0.5～2 h before operation;33.4% used antibiotics at more than 2 h before operation;and 49.7% received antibiotics postoperatively rather than preoperatively.The irrational and nonstandard use of antibiotics manifested as improper in the choice of drug variety,nonstandard in drug combination,irrational in dosage and administration,prolonged use of antibiotics,lacking basis for the change of drug variety etc.CONCLUSION: The prophylactic use of antibiotics in patients with type I incisions from 12 hospitals of Xining area is far from perfect,therefore,it is urgent to strengthen the standard management on the use of antibiotics.
