Objective To explore the effect of clinical and pathological features on the incidence of Hyperuricemia (HUA) in renal glomerular disease.Methods A retrospective analysis was applied to review the clinical and pathological date collected from 3547 patients with renal glomerular disease.These patients were diagnosed as renal glomerular disease by renal biopsy from January 2007 to December 2011.Results (1) HUA incidence was 21.8％ (773/3547) in all of the patients,in which the incidence in secondary glomerular disease 27.2％ (240/882) was much higher than that in primary glomerular disease 20.7％ (552/2665),and the difference was significant (x2 =153.642,P ＜ 0.05).In primary glomerular disease,HUA incidence was the lowest in membranous nephropathy 14.4％ (96/665),while HUA incidence in lupus nephritis (LN) 45.3％(110/243) was the highest and small blood vessel infammation kidney damage 34.7％ (17/49) was the second in secondary glomerular disease.(2) With the increasing of glomerulosclerosis index,tubulointerstitial score,renal vascular lesions score and the stage of chronic kidney disease,HUA incidence increased (x2 =17.798-298.216,P =0.000).(3)Logistic regression analysis showed that high tubulointerstitial score,glomerulosclerosis index and renal dysfunction,male,overweight or obese,hypertension and hypertriglyceridemia were risk factors for hyperuricemia (OR:1.011-7.513,P ＜ 0.05).Conclusion The uric acid level is increased in nearly a quarter of patients with renal glomerular disease.Severe tubulointerstitial lesion,high glomerulosclerosis index,low glomerular filtration rate,male,overweight or obese,hypertension and hypertiglyceridemia were independent risk factors for HUA.

Objective To evaluate a score system(Association of Coloproctology of Great Britain and Ireland ACPGBI)in prediction of postoperative mortality from colorectal cancer patients in a Chinese hospital. Methods We analyzed retrospectively 904 patients with histologically confirmed colorectal cancer who had colorectal surgery from 1992 to 2005.There were 525 colonic cancer patients and 379 rectal cancer patients.We divided patients into several groups according to operative urgency(elective or emergency);surgeons(colorectal specialists or other surgeons);cancer location(colon or rectal).According to ACPGBI score we got the prediction.This prediction was compared with the actual mortality;Chi-square test,receiver operator characteristic curve(ROC),Hosmer-Lemeshow goodness-of-fit test were used.Results Observed overall mortality within 30 days after surgery was 1.0%(9/904),and the predicted mortality was 8.3%(75/904).In all the subgroups the predicted momdity wag higher than observed mortality.We found that the actual mortality was higher in an individual subgroup in which the predicted mortality was higher. Conclusions For colorectal cancer patients undergoing a surgery the predicted mortality of ACPGBI score system was higher than the actual mortality in a Chinese hospital.
