Objective To investigate the relationship of serum ferritin(SF) and acute coronary syndrome(ACS) .Methods ACS group(n= 110) was divided into unstable angina(UA) subgroup(n= 46) ,non-ST-segment elevation myocardial infarction (NSTEMI) subgroup(n=30) and ST-segment elevation myocardial infarction(STEMI) subgroup(n=34) according to clinical da-ta ,coronary angiography and electrocardiogram examination .The normal coronary patients provided as control group(n=42) .The levels of serum ferritin ,hs-CRP and serum lipids were determined and the differences of SF among the groups were analyzed .The correlation of hs-CRP ,TG ,LDL-C ,HDL-C ,TC and SF were also analyzed .Results Compared with control group ,the level of SF in UA ,NSTEMI ,STEMI were significantly increased(P<0 .05) .Comparison in the levels of SF in NSTEMI ,STEMI group and UA group had significant difference(P<0 .05) .Correlation analysis indicated that the level of SF were positively correlated with hs-CRP ,TG and negatively associated with HDL-C .Conclusion The level of SF significantly increased in patients with ACS and has a positive relationship with hs-CRP and the disorder of lipid metablism .SF helps in assessing the clinical classification and risk strati-fication in patients with ACS .

Objective:To analysis the difficulties and complications emerged during transurethral ureteroscopy and offer their management strategies. Methods: A total of 900 patients accepting rigid transurethral ureteroscopy from May 1998 to October 2008, were evaluated retropspeetively. Results: Among 900 cases, 83 cases were found difficulties during transurethral ureteroscopy, of which 45 cases were early cases. 2.6% cases (24 cases) were converted to open surgery, of which 14 cases were early cases. The causes of conversion to open include: ureteral orifice of 3 patients could not be found (12.5%), ureteroscopy failed to enter ureteral orific in 5 patients (20.9%), ureteroscopy failed to get to the ill place in 5 patients (20.9%), ureter perforation occurred in 7 pa-tients (29.1%) , ureter avulsion occurred in 2 patients (8.3%), stones shifted to renal pelvis in 2 patients (8.3%). Conclusions: There are more difficulties and complications during ureteroscopy at early stage. Strictly mastering surgical indications, strengthening preoperative training, mastering the surgical technique is the key to reduce the failure rate and complications of ureteroscopy.
