Objective To summarize the experience of ultrasound-guided percutaneous nephrostomy during percutaneous nephrolithotomy(PCNL) under B-ultrasound guidance. Methods A ultrasound-guided percutaneous nephrostomy was performed in 43 cases by using a 18-gauge needle.Then the percutaneous puncture was expanded for establishing a working tunnel. Under nephroscope,stone fragmentation was completed in the renal pelvis and the upper segment of the ureter.Results The success rate of percutaneous puncture was 100%.Of the 43 cases,the percutaneous working tunnel was successfully established in 42 cases(97.7%),while a conversion to open surgery was needed in 1 case because of uncontrolled hemorrhage after puncture.The overall stone clearance rate was 100%(42/42),including 38 cases of stone removal on one session and 4 cases of two-staged clearance.No serious complications,such as massive hemorrhage or neighboring organ injuries,were encountered.Re-examinations with B-ultrasonography or KUB at 1 month after operation showed no residual stones.Conclusions Ultrasound-guided percutaneous nephrostomy is minimally invasive,safe,and reliable.Proper use of this technique is crucial for a successful performance of percutaneous nephrolithotomy in the treatment of upper urinary tract calculus.

This article has shown the experiences to achieve more effective teaching results by integration of multiple teaching patterns,including case-based,problem-based learning,in the teaching of water-electrolyte metabolism and acid-base balance disorders.

Objective To explore the application and effect of scene imitation method in the education of patients before fiberoptic bronchoscopy.Methods 264 elective bronchoscopy patients between March 2007 and Decembet 2007 were randomly divided into control group(120 patients)and the experiment group(144 patients)Traditional health education was applied in the control group before bronehoscopy.Scene imitation method in health education was applied in the experiment group before bronchoscopy.Results The examination succes rate in the experiment group was significantly improved(P＜0.05).The medical order obeying behavior(MOOB)of the patients was significantly different between the two group(P＜0.01).Conclusion Before the use of fiberoptic bronchoscopy,the new scene simulation method Can help patients on the list obtain more cognitive ability about the testing.Comparing the traditional education,it establishes a sound relationship between doctors and patients,reduces complication and leads to more accurency of testing,thus helping patients to recover soon.

Objective to observe the efficacy and application value of PFNA and Gamma in the treatment of intertrochanteric fractures in elderly. Methods 100 patients with intertrochanteric fractures were divided into PFNA group and Gamma group, who received PFNA treatment and Gamma treatment respectively. And the operation status of patients at different ages,postoperative recovery,and complications were observed. Results The operation time,intraoperatve blood soss of PFNA group were lower than those of Gamma group(P<0. 05). There was no significant difference in fracture healing time. The Harris score of the over 75s in PFNA group was higher than that in Gamma group(P<0. 05),and the complications were less than Gamma group(P<0. 05). Conclusion PFNA was suitable for the patients at differ-ent ages with the advantages of more rigid fixation,good anti-rotation,fewer trauma and fewer complications.

Objective To find out about the utilization of health resources by rural pulic health centers in Hubei Province in the Ninth Five-Year Plan period so as to provide primary information for the better use of rural health resources. Methods The issues of Hubei Health Statistics and Hubei Almanac in 1990 and from 1996 to 2000 were collected and statistial analyses were conducted by means of the spss software. Results In the Ninth Five-Year Plan period, the human resources and fixed assets of rural public health centers in Hubei Province kept increasing whereas the volume of services dropped year by year. The reduction in the average number of outpatient visits and discharged patients per annum was respectively 4. 42% and 4. 09%. The efficiency of the health personnel in delivering medical services has been decreasing, with the average number of patients treated by each person per annum, the annual number of beds utilized, and the annual number of discharged patients in 2000 dropping respectively by 27.54% , 30.22% and 26.36% , as compared with 1996. The annual ratio of bed utilization was around 30% and the number of bed turnovers was about 20 times, evidencing, moreover, a tendency of going down. Conclusion The input of health resources in the rural public health centers in Hubei Province in the Ninth Five-Year Plan period increased while the rate of utilization dropped. It is suggested that integrated management in the rural areas be adopted, better utilization of health resources made, reform of the public health centers deepened, and internal management improved; greater stress be laid on improving the quality of rural health personnel; and the rural cooperative medical and health system be perfected.

Objective To investigate the correlation between atherosclerotic renal artery stenosis and hypertension.Methods One hundred and seventy-nine patients underwent renal artery angiography after coronary artery angiography. Results Among the 179 patients, 56.4% patients were detected as renal artery normal, 24% as renal artery disease, and 19.6% as renal artery stenosis. Compared with hypertensive patients with normal renal artery, ARAS patients had higher systolic blood pressure (148?23 mm?Hg vs 136?18 mm?Hg, P

Objective To investigate the correlation between atherosclerotic renal artery stenosis and the severity of coronary lesions in patients with confirmed coronary artery disease and the impact of renal artery stenosis on serum inflammation related factors.Methods 163 patients from Peking University First Hospital with confirmed coronary heart disease by coronary angiography underwent selective renal artery angiography from Dec 2002 to Sep 2003.Serum hypersensitive C reactive protein(hs-CRP)and Interleukin-6(IL-6)were measured.Results Patients combined with coronary disease and renal artery stenosis were presented with more acute coronary syndrome(ACS)and triple-vessel CAD.Serum hs-CRP and IL-6 levels were also higher in this group.Conclusion Renal artery stenosis is correlated with severe coronary disease.Inflammation state could be one of the reasons for this connection.

Objective To analyze the clinical features and risk factors of invasive fungal infections (IFI) in children with acute leukemia.Methods Ninety-six acute leukemia children complicated with IFI admitted in Guangzhou Women and Children's Medical Center during January 2005 and February 2017 were retrospectively reviewed, and 96 cases of acute leukemia without IFI admitted at the same period were randomly selected as control group.The clinical manifestations of IFI were analyzed, multivariate Logistic regression was used to study risk factors of the complication of IFI in pediatric acute leukemia.Results Among 96 children complicated with IFI, fungus were detected in samples from sputum, bronchoalveolar lavage fluid, or blood in 78 cases, in which 42 cases (43.75％) were oral infection, 36 cases (37.50％) were pulmonary infection.Candida albicans (33.33％, 26/78) was the most commonly isolated pathogen, followed by Candida parapsilosis (20.51％, 16/78) and Candida tropicalis (20.51％, 16/78).Univariate analysis revealed hormone-containing chemotherapy, neutropenia (＜ 0.5 × 109/L), time duration of neutropenia ≥ 10 days, usage of carbapenem antibiotics and combined drug administration ≥2 types were associated with fungal infection (P ＜ 0.05 or ＜0.01).Multivariate Logistic regression showed that the time duration of neutropenia ≥ 10 days (OR =11.390, 95％ CI 4.145-55.263, P ＜ 0.01),usage of carbapenem antibiotics (OR =4.825, 95％ CI 1.681-13.842, P ＜ 0.01) and hormone-containing chemotherapy (OR =2.220, 95％ CI 1.542-8.246, P ＜ 0.05) were the independent risk factors of IFI.Conclusion Rational usage of antibiotics and effective measures taken to restore the granulocytes can help to reduce the incidence of IFI in children with acute leukemia.
