Objective To evaluate the safety and feasibility of minimally invasive percutaneous nephrolithotomy (mPCNL) for the treatment of upper urinary tract calculi. Methods From October 2003 to December 2006, mPCNL was performed on 127 patients suffering from upper urinary tract calculi by using Karl Storz F8/9.8 rigid ureteroscope and homemade pneumatic ballistic lithotriptor. Results Of the 127 cases, mPCNL was completed in 125, and was converted to open surgery in 2. The rate of stone removal was 89.8% (114/127). The operation time was 78-185 min (mean 108 min). Nephrostomy tube was kept for a mean of 7 d (5-11 d). The mean hospital stay was 8.1 d (5-12 d). Two patients received blood transfusion during the operation. One patient developed massive hemorrhage at the nephrostomy opening, and was cured by high-selective renal artery embolization. Among the patients, 117 were followed up for 1-16 months (mean 5.3), during which no recurrent urinary tract stones was found by B-ultrasonography or X-ray. Conclusions By using mPCNL, patients with upper urinary tract calculi can be treated safely and effectively with a high rate of stone removal, less trauma, quick recovery, and short hospital stay.

Objective To supervise the colonoscopy following up in the high risk colorectal cancer patients are good to find out early stage cancer and adenoma in time and prevent the latter to evolve in to cancer. Methods From Aug. 1995 to Mar. 2000, 1 125 cases of high risk colorectal cancer have received the colonoscopy .Of them, 353 cases who have symptoms after having the physical examination in clinics; 125 cases have the colorectal cancer family history without any symptoms; 386 cases have had operated on the colorectal cancer; and 261 cases with the colorectal adenoma after high frequency electrotomy under endoscopy in one year. Results In 353 cases, 52 cases (14.7%) with adenoma and 17 cases (4.8%) with colorectal cancer are found, and 12 cases (70.5%)of the latter are of early stage cancer without any lymph node metastasis. Among the 125 cases there were 26 cases (21.6%) with adenoma, 4 cases (3.2%) with colorectal cancer and 2 cases (1.6%) with adenoma early stage cancer. Among the latter 6 cases, 5 cases are of the early stage cancer without any lymph node metastasis. Of the 386 cases , 81 cases (20.9%) of adenoma, 3 cases (0.7%) of the third primary cancer, and 11 cases (2.8%) of second primary cancer were found in which 11 cases (78.5%) are of the early stage cancer without any lymph node metastasis. In 261 cases there were 56 cases (21.4%) with adenoma, among them, 41 cases (73.2%) are the newly found adenoma with diameter 1cm in diameter were missed in the first colonoscopy.Conclusion A total of 1 125 cases with high risk colorectal cancer were examined by colonoscopy, it was found 37 cases (3.3%) with carcinoma, in which 28 cases (75.7%) with early cancer of no lymph node metastasis, and other 215 cases (19.1%) with adenoma.

Objective:To investigate the expressions of P27kipl (P27) protein and cyclin E protein in human renal cell carcinoma and in paracarcinoma kidney cortex tissue,and to explore the correlation of these protein expressions with biological behavior of tumors.Methods:P27 and cyclin E expressions were studied in formalin-fixed,paraffin-embedded sections of renal cell carcinoma and in paracarcinoma kidney cortex tissue by means of a specific and sensitive immunohistochemical S-P assay.Results:The positive rates of P27 protein and cyclin E protein in renal cell carcinoma were significantly higher than those in paracarcinoma kidney cortex tissues ( P

Objective To develop clinical dual-qualification nursing teachers stressors scale. Methods Based on literature review, semi-structured interview and the Delphi, first of all, the item pool was made up, then the pre-test scale was formatted. 167 dual-qualification nursing teachers participated in this investigation.Finally, the official scale was formed after measuring its reliability and validity. Results The scale was made up of six dimensions and 25 items. The Cronbach's α was 0.652 ～ 0.903, and the intraclass correlation coefficient was 0.716 ～ 0.921. Conclusion The process of this scale is scientific, rational, rigorous. The scale has good psychometric characteristics and can be used for the stress assessment of dual-qualification nursing teachers.

Objective To investigate the recognition of graded nursing and its influencing factors among nursing assistants in elder homes.Methods A questionnaire survey was conducted on 116 nursing assistants.Results The nursing assistants showed insufficient recognition of graded nursing,there were significant differences in role cognition,operation and practice training,salary,and the nursing workload,there were no significant differences in working years and educational levels.Conclusions The recognition of graded nursing was insufficient.It is suggested to increase the role cognition education,enhance the theory and practice training,provide higher salaries and allocate workload reasonably to ensure the implementation of graded nursing and increase the satisfaction level of the elderly.

Objective To explore the feelings of the caregivers of dementia patients,and find the resource of the caregiver's abuse tendency to dementia patients in community.Methods The data of 10 caregivers were collected through deep interviews,and the Colaizzi analysis method was used to analyze the data.Results Through repeatedly reading,arranging,analysis,separation,and theme refining,five themes were drawn:lack of related knowledge and care skills,care tasks making caregivers tired,the economic burden,lack of social support,low sense of worth.Conclusions When concerning the problems caused by dementia patients,it's necessary to appeal the society and government to provide feasible service and assistance on the issue of abuse tendency,which is produced by the caregivers during the process of taking care of them.

Objective To investigate the efficacy of clinical case-based PBL in clinical practice in department of urology.Methods Medical students admitted by our clinical medical school in 2006 and 2007 were involved.Fifty-six students of 2007 grade were chosen as study group while 49students of 2006 grade as control group.Students in study group were taught by clinical case-based PBL method while those in control group by traditional method.All results were analyzed by SPSS 11.0.Results The scores in study group were higher than those in control group with statistical differences (82.84 ± 12.35 vs.72.95 ± 11.13 ; t =4.29,P ＜ 0.01).Students in study group showed more interests in practice lessons.Teachers were more satisfied with the overall performance of students in study group.Conclusions Clinical case-based PBL can increase students' overall performance such as better coordination,better clinical skills and better open-minded clinical case solution.

Objective To investigate the application value of the Mini-Nutritional Assessment (MNA) in assessing the nutritional status in middle-aged women with diabetes.Methods Using the normal range of traditional nutritional index as the reference standard,two hundred and forty middle-aged women with diabetes were recruited and their nutritional status were assessed by MNA and laboratory test (including PAB,Fib,TLC,CHOL),respectively.Finally,the results were analyzed and compared.Results The correlation coefficient of MNA value and BMI、PAB,Hb,TLC,CHOL were 0.571,0.614,0.781,0.568,0.218.MNA had good correlations with several traditional laboratory indicators regarding with nutritional status,with signifi-cant difference.In this study,the results of investigation by MNA showed that:the rates of malnutrition,potential malnutrition,and normal nutritional were 30％(72 cases),65％(156 cases),and 5％(12 cases),respectively.The sensitivity and specificity of MNA were 96.1％ and 98.2％ respectively.Laboratory testing resuits:malnutrition and normal nutrition were 31％ (74 cases) and 4％ (10 cases).Kappa test(Kappa=0.922):the results of MNA and laboratory testing had strong consistency.Conclusions MNA is feasible in assessing nutritional status in the domestic middle-aged women with diabetes.

ObjectiveTo constructe the quality-evaluation index system of clinical teaching of operating room. MethodsThe quality-evaluation indicator system was constructed using literature study and Delphi. Then the Precedence Chart and Analytic Hierarchy Process was adopted to ensure the index's weight. ResultsThe scale was formed by 5 items of level 1 and 21 items of level 2 of the index system. ConclusionThe index system has high reliability,which can be confirmed from experts' authority degree, their attentive involvement and the concentrating degree of the views. The Quality-Evaluation Index System ( QEIS ) is constructed which can be used to evaluate clinical teaching of operating room.
