Objective To determine the efficacy and safety of intravenous iron sucrose and oral iron dextran in renal anemia patients. Methods Sixty renal anemia patients were randomized into two groups:intravenous iron group(IV group, 100 mg iron sucrose twice a week) and oral iron group(oral group, 150 mg iron dextran every day). The changes in hemoglobin (Hb),hematocrit (Hct),serum ferritin (SF),and transferrin saturation (TSAT) were assessed on week 4,8, and 12 after treatment. The maintenance dosages of erythropoietin (EPO) after reaching treatment target and the adverse events were also observed. Results Hb increased after treatment in IV group [(79.87 ± 13.19) g/L to (106.11 ± 12.38) g/L] and oral group [(85.41 ± 11.49) g/L to (94.68 ± 10.06) g/L],and compared with that before treatment, there was significant difference in each group(P< 0.01 ). Also significant difference showed in Hb levels after treatment between two groups(P< 0.01 ). SF and TSAT levels were higher after treatment in IV group than those in oral group (P < 0.01 ). The adverse event was lower in IV group (0) than that in oral group (16.7%,5/30).Conclusions Oral iron dextran which has more adverse events and poor efficacy in curing anemia, can not correct anemia ideally. Meanwhile intravenous iron sucrose has positive effects on renal anemia with low adverse events, and it can be used as a long term iron supplementation in hemodialysis patients.

Multiagent chemotherapy has significantly improved survival for childhood ALL.However,the relapse rate with current therapies remains at 20% to 30%.Numerous studies have proved that the minimal residual disease(MRD)is associated with relapse rate.The major methods for the detection of MRD include polymerase chain reaction(PCR)and flow cytometry(FCM).The measurement of MRD in childhood acute lymphoblastic leukemia offers the promise of individualized,risk-stratified treatment and the prediction for post-transplant outcome.

It is important that the oral hospital establish a guarantee system of medical graduation clinical practice quality. Having experienced clinical education for many years,the hospital has formed a system in order to achieve objective management and process management organic unification,which can gradually promote the clinical practice quality.

Objective To investigate the diagnostic and predict vaIue of procalcitonin (PCT) in ICU patients with sepsis and the correlation between PCT concentration and positive results of bacterial culture.Methods A total of 278 patients with sepsis were admitted into emergency ICU,general ICU and respiratory ICU from October 2011 to September 2012.Of them,193 patients had definite microbial infection evidence.Serum PCT levels among groups of different pathogens were compared.The analysis of correlation between the PCT concentration of the first assay was got after admission and short-term prognosis was evaluated.The correlation between PCT level and positive results of bacterial culture was also evaluated.Results Spearman correlation analysis showed that serum PCT levels of bacterial infections in patients with sepsis were significantly higher than those of the non-bacterial infections in patients with sepsis (P =0.001).And there was a positive correlation between the PCT concentration of the first specimen after admission and 7-day in-hospital mortality in patients with sepsis due to bacterial infections (r =0.277,P =0.004).The patients with PCT levels greater than 2 ng/ml had high vulnerability to bacterial infection Conclusions The PCT concentration of the first assay after admission was positively correlated to 7-day mortality in ICU patients with sepsis due to bacterial infections.The serum PCT concentration indicated the severity of host response to the bacterial infection.And etiological evidence directly showed pathogenic factors.Both of PCT and etiological evidence related to bacterial infection,reflected different aspects of bacterial infection.

Objective To evaluate the diagnostic and predict value of procalcitonin (PCT) levels in patients diagnosis of sepsis with immune system defect in the intensive care unit (ICU).Methods This is a retrospective analysis.We enrolled 278 patients diagnosis of sepsis in Emergency ICU,general ICU and Respiratory ICU in Renmin Hospital of Wuhan University from October 2011 to September 2012.Among them,122 patients have normal immune function and 156 patients have auto-immune system diseases or/and requiring corticosteroids or chemotherapy.According to the APACHE Ⅱ score,patients were divided into low-risk group,middle-risk group and high-risk group,and their PCT levels were compared.Logistic regression analysis of the multiple factors was used to screen independent risk factors for predicting 7 days' mortality.The predictive ability was also evaluated and compared between the first time of PCT concentration after admission and dynamic change of PCT within the first week with area under receiver operator's characteristic curve (ROC curve,AUC).Result The results of Spearman correlation analysis showed that there was a significant positive correlation between the patients' PCT concentration and APACHE Ⅱ score (r =0.979,P ＜ 0.05).And there was a positive correlation between the first PCT concentration after admission and 7 days' mortality in-hospital (r =0.826,P ＜ 0.05).Multiple factors logistic regression analysis indicated that both the first time PCT concentration after admission and APACHE Ⅱ score of patients were independent risk factors for predicting 7 days' mortality (PCT OR =1.77,95％ CI =1.28-3.83,P =0.0023).The warning value of 7 days' mortality for patients with normal immune function was PCT≥7.18 ng/ml and for those with abnormal immune function was PCT ≥ 3.52 ng/ml.Compared to dynamic monitoring of PCT,there was no significant difference in sensitivity but specificity is less than the dynamic monitoring of PCT.Conclusions The diagnostic and predict value of procalcitonin (PCT) levels were not affected by the immuno-suppressive therapy.The first time PCT concentration after admission was an independent risk factor for predict of 7 days' mortality in ICU patients with sepsis.The PCT warning value of the sepsis patients with abnormal immune function was much lower compared to those with normal immune function.
