Objective To investigate the application value of multifunctional dynamic flat panel X-ray detector in intravenous pyelography.Methods Total 540 patients with intravenous pyelography were divided into multifunctional dynamic flat panel X-ray detector group (300 cases) and conventional flat panel X-ray detector group (240 cases) by random digits table method.Image quality,radiation dosage and examination time were analyzed and compared between the two groups.Results There was no statistical difference between the two groups in image quality (P > 0.05).The examination time and radiation dosage was (25.5 ± 8.2) min and (12.5 ± 6.8) mAs respectively in multifunctional dynamic flat panel X-ray detector group and (39.2 ± 12.1) min and (23.6 ± 7.6) mAs in conventional flat panel X-ray detector group.The differences had statistical significance (P < 0.01).Conclusions Multifunctional dynamic flat panel X-ray detector in intravenous pyelography can provide lower radiation dose,shorter examination time and higher image quality.It has obvious advantages in urography.

Background and purpose:With the recognition of prognostic factors and application of surgical- pathological staging,the treatment strategy of endometrial cancer has greatly changed.In this study,we investigated the treatment strategy,survival rate and prognostic factors of endometrial cancer.Methods:Five hundred and fifty-nine patients of endometrial cancer underwent primary surgical treatment from January 1996 to December 2006 in Cancer Hospital,Fudan University.The clinicopathologic parameters and prognosis were analyzed retrospectively.Results: Patients were followed up with the median period 36 months,25 cases experienced local relapse,24 cases were found to have distant metastases.The 3-year overall survival(OS)was 88.7%,3-year and 5-year disease free survival(DFS) was 82.7% and 80.9%.The 3-year overall survival(OS)were 95.5% in stageⅠ,95.3% in stageⅡ,75.9% in stageⅢand 32.4% in stageⅣrespectively(P

Objective To investigate the effects of heparin coating on intimal hyperplasia in implanted decellularized xenografts.Methods The resected canie carotid arteries were decellularized,and heparin coating was partially performed.Eighteen rabbits were divided into non-heparin-coated group(n=9)and heparin-coated group(n=9).During implantation,only the left carotid between the anastomotic stoma was ligated.Doppler ultrasonography was performed 1,3 and 12 weeks post-implantation to measure the luminal diameter,and the hemodynamic parameters such as PSV,RI and PI were calculated.All animals were sacrificed,histological observations were conducted at 12 weeks post-implantation,and I/(I+ M)was calculated.Results Except for 1 week post-implantation in the ligated side,the luminal diameters in non-heparin -coated group were significantly smaller than that of pre-implantation.Besides,those of the non-ligated side at each time points were significantly smaller than the ligated side(P

In order to obtain an efficient screening procedure for identification of succinate producing anaerobic strains,a semi-quantitative paper chromatography method was developed. Lactic acid and acetic acid were identified as the main byproducts in the process of succinate production by the high performance liquid chromatography (HPLC).Succinic acid was completely separated from the byproducts of lactic acid and acetic acid in the same broth developed by paper chromatography.The content of succinic acid was calculated by a semi-quantitative method.The results showed that paper chromatography was a simple and cost effective method that could be utilized to screen anaerobic strains producing succinic acid.

AIM: To analyze the results of phacovitrectomy with internal limiting membrane(ILM) peeling to treat foveoschisis in ultra-high myopia.METHODS: Totally 32 eyes of 32 ultra-high myopia patients with foveoschisis were selected retrospectively.The preoperative refractive errors ranged from-12.00D to-20.00D with the mean of-15.78±2.16D.The best corrected visiual acuity(BCVA) were converted to LogMAR acuity, and the average BCVA was 4.1±0.4.Conventional phacovitrectomy with ILM peeling by ICG dying were performed.Gas tamponade were performed to end the operation.The BCVA and the foveoschisis cavity were observed by 1-9mo after the surgery, with the mean of 4.5mo.RESULTS: The foveoschisis cavity of 30 eyes were healed with BCVA increased and visual distortion alleviated distinctly (94%)(t=-7.91, P<0.05).CONCLUSION: Phacovitrectomy with ILM peeling is useful in treating foveoschisis in ultra-high myopia with visual function preserving.

Objective To analyse the diagnosis and treatment of testicular torsion. Methods The clinical data of 66 cases of testicular torsion were retrospectively analysed. Results Among the 66 cases,32(48.5%) paid the first medical visit within 10 h,and 24(36.4%)were confirmed diagnosis at the first visit.False negative results occurred with color Doppler flow imaging(CDFI),and 8 testicles were damaged due to the false negative diagnosis.Thirty-three patients without prophylactic contralateral orchidopexy were followed up for 6 months to 20 years,and one experienced recurrent torsion. Conclusion The testicular torsion must be considered when a sudden acute scrotum pain is occurred.Testicular damage is closely related to the torsion time,and delayed medical intervention contributes to the testicular damage.Highly suspected cases should be performed surgical exploration timely due to the false negative results with CDFI.Prophylactic contralateral orchidopexy is recommended.
