Lung nodules are one of the most common pathological changes, thus early detection of lung nodule is very important for the diagnosis medical treatment of lung eancer. In recent years, as the application of multi-slice spiral CT(MSCT), high-resolution CT(HRCT) and low-dose chest CTCLDCT), computer-aided diagnosis (CAD) system will be more essential and more important. Since CAD system can improve the working efficiency of doctors and provide service to more patients, has become the research hotspot and achievement has been made in relevant area internationally recently. This review summarizes the basic methods and applieations of computer-aided detection and diagnosis of lung nodule based on CT image.

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.

Diffuse large B-cell lymphoma is the most common histology of non-Hodgkin lymphoma and is composed of clinically and pathologically heterogeneous group.The ESMO clinical practice guidelines stratified the diseases according to age,age-adjusted IPI and feasibility of dose-intensified approaches.While the regimens suggested by ESMO are almost the same:six to eight cycles of chemotherapy with CHOP combined with rituximah.This article discussed the inadequacies of the guideline according to the recent clinical and pre-clinical studies and the authors' personal experiences.Four deficiencies are outlined:new prognostic factors are not included for the stratification,no therapy adjustmett was advised according to the response,overload therapy for the very-low risk patient,and insufficient therapy for the young,high-risk patients.

Objective To standardize Adaptive Behavior Assessment System (ABAS)-II Chinese version to establish norm of ABAS-II Chinese version (6-18 years old). Methods International Classification of Functioning, Disability and Health (ICF) and psychological mea-surement were taken. Results Chinese version of ABAS-II (6-18 years old) was developed. The norms of general scores, main domains scores and adaptive skill scores had been established. Conclusion Chinese version of ABAS-II (6-18 years old) can be applied for the evalu-ation of adaptive behavior for Chinese children aged 6-18 years. The standardized Chinese version of ABAS-II (6-18 years old) meets the re-quirement of reliability and validity of the US version.

Objective To evaluate the effectiveness of aerobic exercise on quality of life in breast cancer survivors.Methods Electronic databases were searched.Randomized controlled trials in which aerobic exercise was compared with controls regarding quality of life in breast cancer survivors were included.Results We analyzed 12 RCT studies.Aerobic exercise significantly improved quality of life in breast cancer survivors.Seven studies which used FACT-B scale concluded that aerobic exercise could significantly improve psychological emotion,social/family function and breast-related function.The aerobic exercise aiming at breast cancer survivors who had already finished all the therapies except endocrine therapy of breast cancer,mainly comprised of short-period intervention programs (within 24 weeks),and was advised to be executed under professionals' supervision to ensure safety.Conclusion Aerobic exercise could effectively improve quality of life in breast cancer survivors,especially in aspects of psychological emotion,social/family function and breast-related function.

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 explore the value of ultrasonographic diagnosis of deltoid contracture (DC). Methods A total of 37 children with bilateral asymmetric shoulder were reviewed retrospectively, and 8 cases with 9 shoulders were surgically confirmed DC. The results of the ultrasonography and surgery were compared. Results The sensitivity of ultrasonographic diagnosis of DC was 88.89% and specificity was 100%. No statistically significant difference of contracture thickness measurement was found between surgery and ultrasonography. Ultrasonographic findings of DC in children included hyperechoic areas (7 cases) or hypoechoic area (1 case). Conclusion Ultrasounogrphy is an effective method for diagnosis of DC in children.

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.
