RESUMO
Objective To discuss the significance of the application of neutrophil to lymphocyte ratio (NLR)combined with prostate specific antigen (PSA)in early diagnosis of prostate carcinoma.Methods 120 cases with surgery treatment of prostate carcinoma were selected as study group,and 120 healthy people were selected as control groups.The NLR and PSA were tested to diagnose the prostate carcinoma.The critical value of NLR in diagnosing prostate carcinoma was evaluated by ROC curves,and the advantages of combination of NLR and PSA were judged. Results By using ROC curves to evaluate the NLR in diagnosis,the critical value was 2.75.The susceptibility, specificity,Youden index,correct index were 0.79,0.85,0.65,0.72.The susceptibility,specificity,positive predictive value,negative predictive value,correct index of NLR combined with PSA in diagnosing the prostate carcinoma were 0.85,0.83,5.00,0.18,0.68.Conclusion The application of NLR has higher susceptibility and specificity to diagnose prostate carcinoma.NLR combined with PSA can improve the susceptibility and specificity of early diagnosis of prostate carcinoma.
RESUMO
Objective To investigate the clinical applicated value of simple transumbilical single-tunnel laparoscopic renal cyst decortication.Methods 7 patients with renal cysts were treated with simple single-tunnel laparoscopic renal cyst decortication.Results The operations of 7 patients were succeed.The mean operative time was 37 (28 ～ 90) min,and the mean time of pulling the drain tube out was 2 (1 ～ 4) d,and the mean int aoperative blood loss was 30 (25 ～ 80) ml,and the mean bed stay was 1.5 (1 ～ 3) d,and the mean hospital stay was 4 (3 ～ 8) d.In 7 patients,no recurrence of the cyst occurred during a follow-up of 1 ～ 6 months by color-ultrasonography,CT after operation.Conclusion The simple transumbilical single-tunnel laparoscopic renal cyst decortication has advantages of economic,minimal trauma,hairdressing,rapid recovery and better effect,therefore it maybe an ideal treatment choice for renal cysts.
RESUMO
Solitary fibrous tumor (SFT) in bladder is extremely rare. In this study, we reported one case of bladder SFT and reviewed the only ten cases of the disease that had been reported so far. The patient suffered from residual urine sensation and urethral pain. Cystoscopy revealed a 7-cm protruding mass at the dome of the bladder, and bladder mucosa biopsy showed normal differentiation of the bladder mucosa with a small amount of inflammatory cells. Radical resection of the tumor was performed in this patient. Pathological examination found uniform, haphazardly arranged spindle cells, the majority of which were CD34-positive and Vimentin-positive and proved that the mass was a solitary fibrous tumor. Within a period of 9 months of follow-up, no reoccurrence was found.
RESUMO
To investigate the exon mutation of vitamin K-dependent gamma-glutamyl carboxylase (GGCX or VKDC) in patients with calcium oxalate urolithasis, renal cortex and peripheral blood samples were obtained from severe hydronephrosis patients (with or without calculi), and renal tumor patients undergoing nephrectomy. GGCX mutations in all 15 exons were examined in 44 patients with calcium oxalate urolithiasis (COU) by polymerase chain reaction (PCR) and denatured high pressure liquid chromatography (DHPLC), and confirmed by sequencing. Mutation was not found in all COU samples compared to the controls. These data demonstrated that functional GGCX mutations in all 15 exons do not occur in most COU patients. It was suggested that there may be no significant association between the low activity and mutation of GGCX in COU.
