Objective To study the features of clinic ,pathology and prognosis in children with steroid-resistant nephritic syn-drome(SRNS) .Methods Children with SRNS hospitalized in Division of Nephrology and Immunology in our hospital from January 2003 to December 2012 were analyzed retrospectively in clinic ,pathology and prognosis .Results 162 patients were investigated , which accounted for 10 .8% of children with Primary nephritic syndrome(PNS) ,and the mean age of onset was 6 .9 ± 3 .8 years old . Renal biopsy was performed in 132 patients ,60 of them showed mesangial proliferative glomerulonephritis(MsPGN) ,30 showed fo-cal segmental glomerulosclerosis(FSGS) ,19 showed minimal change disease(MCD) ,8 showed membranoproliferative glomerulone-phritis(MPGN) ,5 showed membranous nephropathy(MN) ,1 showed proliferative sclerosis glomerulonephritis(PSGN) .Patients with non-minimal change disease(non-MCD)had a significant prevalence of hematuria .The distribution of pathologic type among age groups and clinical classification was significantly different ,respectively(P<0 .05) .(2)132 patients were followed up ,58 of them were in complete remission ,26 were in partial remission ,15 were not in remission ,8 were dead ,and the mean time for com-plete remission was 15 months(3-84 .Prognosis correlated with pathologic type(P<0 .01) .Conclusion (1)There is a preponder-ance of non-MCD in children with SRNS ,and MsPGN and FSGS is the major pathologic type .Hematuria is a predictor of glucocor-ticoid resistance .(2)Children with SRNS have a long time proteinuria and poor prognosis .FSGS has a poor prognosis ,when com-pared with MsPGN .

Objective To understand the clinical significance of serum immunoglobulins and C3 at the initial episode on the treat-ment and prognosis of childhood primary nephrotic syndrome(PNS) .Methods 426 children patients with first episode of PNS ad-mitted to the nephrology department of our hospital from January 1 ,2003 to December 30 ,2012 were retrospectively analyzed .The clinical data were collected for conducting the analysis on the immuneglobulins and C 3 levels in different age groups ,clinical classifi-cation ,hormone response ,recurrence ,prognosis and correlation among various pathological types .Results (1)Compared with the healthy children ,the peripheral blood IgG level in childhood PNS was significantly decreased ,while the IgM and IgE level were sig-nificantly increased .(2)The IgE level in steroid-sensitive nephrotic syndrome(SSNS) was higher than that in steroid-resistant ne-phrotic syndrome(SRNS);which in frequent recurrence nephrotic syndrome was higher than that in non-recurrence nephrotic syn-drome .(3) The C3 level in the PNS children patients aged over 1 years and nephritis nephrotic syndrome(NNS) was lower than that in simple nephrotic syndrome(SNS) .Conclusion PNS is correlated with the immune dysfunction .Serum IgE level increase clinically manifests by the steroid sensitivity and frequent relapse ;the lower the C3 level ,the poorer the prognosis .

Objective To investigate the clinical manifestations, diagnosis and treatment of Bartter syndrome in children. Methods Clinical data of 15 patients with Bartter syndrome in Children`s Hospital Afifliated to Chongqing Medical University was analyzed, and pertinent literatures were reviewed. Results Bartter syndrome is an autosomal recessive inherited renal disorder characterized by hypokalemia, hypochloremia, metabolic alkalosis, vomiting, growth retardation, the activation of the renin-aldosterone axis, normal blood pressure. Genetic analysis is the most reliable way for diagnosis. Comprehensive therapy with antisterone, indomethacin, catopril and potassium have remarkable effect. Conclusions Bartter syndrome should be considered when children have unreasonable continuous hypokalemia, hypochloremia, metabolic alkalosis and growth retardation. It can be clinically diagnosed by clinical manifestation and hydrochlorothiazide test, and genetic analysis is the most reliable way. It can be ameliorated by potassium and magnesium supplementation, antialdosterone medications, prostaglandin inhibitors and antisterone. Considering the following electrolyte disturbances, infections, growth retardation, kidney failure and even death,Bartter syndrome need lifelong treatment, early diagnosis and treatment is of the most importance.

Great advances have been made recently in the therapy of chronic lymphocytic leukemia due mainly to the application of novel agents. In the 58th American Society of Hematology Annual Meeting, the latest outcomes of many clinical studies have been reported. The present article will review the reports and focus on the following studies on chronic lymphocytic leukemia (CLL): the long-term therapeutic outcome of BTKi and the result of combination therapy of BTKi with other agents; the short-term result of bcl-2 inhibitor in CLL; the efficacy of maintenance therapy with lenalidomide in CLL patients; CD19-CAR T-cell therapy achieved good response. Traditional immunochemotherapy with combination of fludarabine, cyclophosphamide and rituximab is still the first-line option for fit patients through long-term follow-up. The allogeneic stem cell transplantation remains a curative strategy for CLL but with stricter indication.

Objective To investigate the clinical value of bloodβ-hydroxybutyric acid and urine ketone in the diagnosis of diabetic ketosis. Methods One hundred and fifteen patients with non-ketosis diabetics (NDK group), 85 patients with diabetic ketosis (DK group) and 105 healthy people (control group) were enrolled in Chengmai People's Hospital from May 2012 to May 2014. Blood β-hydroxybutyric acid, urine ketone and blood glucose were detected; the correlation index of blood β-hydroxybutyric acid, urine ketone and blood glucose in NDK group and DK group were analyzed. The receiver operating characteristic curve (ROC) was performed in determining the diagnostic value of bloodβ-hydroxybutyric acid for diabetic ketosis. Results The level of bloodβ-hydroxybutyric acid, positive rate of bloodβ-hydroxybutyric acid, urine ketone and level of blood glucose in DK group were higher than those in NDK group and NC group (P<0.01) . Blood β-hydroxybutyric acid was positively correlated with urine ketone and blood glucose (r=0.552,P=0.000;r=0.405,P=0.010) . When urine ketone was used as diagnostic standard, the area under curve of bloodβ-hydroxybutyric acid was 0.839, the best cutoff value ofβ-hydroxybutyric acid was 0.64 mmol/L with the sensitivity was 81.6%and specificity was 89.2%. Conclusions Examinations of bloodβ-hydroxybutyric acid and urine ketone have great significance for the diagnosis of diabetic ketosis. The co-monitoring of blood β-hydroxybutyric acid and urine ketone can reduce the rates of missed diagnosis and misdiagnosis. The best cutoff value of β-hydroxybutyric acid to diagnose diabetic ketosis was 0.64 mmol/L.
