OBJECTIVEThe aim of this study was to evaluate the efficacy and toxicity of the CCCG-97 and BFM-90 protocols in the treatment of pediatric patients with B-cell non-Hodgkin's lymphoma (B-NHL) retrospectively, and to explore the optimal therapeutic strategy.

METHODSForty-five consecutive untreated patients (age of 18 years or less) with newly diagnosed B-NHL (including Burkitt Lymphoma and diffuse large B-cell lymphoma), treated in our hospital between July 1999 and December 2008 were enrolled in this study. The patients were classified into 2 groups by different protocols. From July 1999 to December 2004, twenty-one 3- to 13.8-year-old children were enrolled in the CCCG-97 group, with 1 in stage I/II, and 20 in stage III/IV(St Jude staging). From January 2005 to December 2008, twenty-four 2.8- to 14.1-year-old cases were enrolled in the BFM-90 group, with 3 in stage I/II, and 21 in stage III/IV (St Jude staging). The survival rates were evaluated by Kaplan-Meier analysis.

RESULTSForty of the 45 patients (88.9%) reached complete response (CR) after 2 courses of chemotherapy. In the CCCG-97 group, the CR rate was 95.2% (20/21 pts), while that in the BFM-90 group was 83.3% (20/24 pts). At a median follow-up time of 62 (17 to 131) months, the 5-year event-free survival (EFS) was 71.8% for all patients, and 69.1% for Stage III/IV, respectively. In the CCCG-97 group, the 3-year EFS was 76.2%. In the BFM-90 group, it was 75.0%. There was no significant difference in survival rates between the CCCG-97 and BFM-90 groups (P=0.975). Unfavorable events recorded were as follows: Death of progression before achieving CR during induction therapy in 4 cases, and relapse after achieving CR in 6 cases. The relapse rates were 19.0% (4/21 pts) in the CCCG-97 group and 8.3% (2/24 pts) in the BFM-90 group, with a non-significant statistical difference (P=0.292). Major toxicities were myelosuppression and mucositis, especially in the BFM-90 group, but were tolerable and manageable. five patients in the BFM-90 group received rituximab, 2 patients (Stage III) achieved CR, while the other 3 patients (Stage IV) had progressive disease or relapse.

CONCLUSIONSShort-pulse and intensive chemotherapy, stratified according to stage of disease, can improve the survival rate of pediatric mature B-NHL. The efficacy of the CCCG-97 protocol and BFM-90 protocol is comparable and the toxicity is tolerable.

To study the influence of IFN-alpha on function of CML-DC cultured in vitro and expression of chemokine and its chemokine receptor, bone marrow mononuclear cells from 13 CML patients were cultured in the fetal calf serum culture system supplemented with rhSCF, rhFlt-3L for expansion system, and adding rhGM-CSF, rhTNF-alpha, rhIL-4, with or without rhIFN-alpha to induce DCs. After incubation for two weeks, the phenotypes of CML-DC were analyzed by direct immunofluorescence and flow cytometry. The concentration of MIP-3beta expressed by CML-DC in the supernatant were analyzed by ELISA. The proliferative ability of T cells from healthy volunteers stimulated by CML-DCs were measured by MTT assay. The results showed that expression of CD86, CD83, CD40, MHC-I class molecules, CCR7, the concentration of MIP-3beta expressed by CML-DC, and the proliferative ability of T cells stimulated by CML-DCs in IFN-alpha group were all significantly higher than that in control group (P < 0.01). It is concluded that the immunophenotype of CML-DCs can be partially changed by IFN-alpha to accelerate the maturation of CML-DCs, enhance the capacity of CML-DCs, and stimulate allogeneic T lymphocyte proliferation.

OBJECTIVETo evaluate the amount of blood loss and the efficacy of clotting factor in controlling blood loss during total knee arthroplasty.

METHODSThe medical documents of 18 patients with haemophilic arthritis (HA) secondary to haemophilia A and 19 patients with osteoarthritis (OA) were retrospectively reviewed. Demographic data,functional and hematological test results,the amount of blood loss and transfusion,and complications were analyzed.

RESULTSThe median amounts of total and external blood loss were 2240 ml(1892-3415 ml) and 1326 ml(934-2256 ml)in the HA group, which were significant higher than those in the OA group [1746 ml(1259-2246 ml)and 846 ml (504-1217 ml), respectively]. The median amounts of external blood loss in the two groups were 680 ml(370-1330 ml)and 730 ml(200-1190 ml)and there was no significant difference(p=0.620). Moreover, more patients in the HA group required blood transfusion (84.2% vs. 47.4%), and more red cells were transfused per patient in the HA group (2.3 U vs. 0 U).

CONCLUSIONSThe total blood loss and hidden blood loss are higher in the HA patients than in OA patients during total knee arthroplasty, although the external blood loss is basically the same. Management with more clotting factor may decrease the blood loss in HA patients.

Objective To analyze the clinical features of isolated hematuria Henoch-Schonlein purpura nephritis (HSPN). Methods The clinical data of children with isolated hematuria HSPN diagnosed in the First Affiliated Hospital of Henan University of Chinese Medicine from November 2003 to December 2014 was analyzed retrospectively. Results One hundred and thirty-five isolated hematuria HSPN patients were rolled in the study. Eighty cases were male and fifty-five cases were female. Male to female was 1. 45:1,average age was(9. 24 ± 5. 32)years old. Thirty one cases had pure skin purpura, thirty three cases had purpura accompany with abdominal pain,twenty eight cases had purpura accompany with arthralgia,forty three purpura accompany with abdominal pain and arthralgia. The pathogenesis was (8. 62 ± 7. 28)months. Seven cases were given nephridial tissue biopsy. In the 135 cases,there were 31 cases accepted general therapy,and 104 cases accepted the ther-apy of immunodepressant. In the patients with general therapy,there were 19 cases with recovery,8 cases with isolated hematu-ria,3 cases with mild proteinuria,1 case with moderate proteinuria. In the patients with therapy of immunodepressant,there were 72 cases with recovery,23 cases with isolated hematuria,7 cases with mild proteinuria,one case with moderate proteinuria,one case severe proteinuria. There was no significant difference in the prognosis between the general therapy patients and immu-nodepressant therapy patients(z = 0. 65,P = 0. 516). Conclusion The prognosis of the HSPN in children accompany with iso-lated haematuria is favourable,but a few patients may progress to moderate and severe proteinuria.

OBJECTIVETo estimate the relative risks of dyslipidemia, hypertension, diabetes mellitus, and metabolic syndromes among overweight and obese Chinese children compared with their normal weight counterparts.

METHODSOverweight and obesity were defined by age- and sex-specific BMI classification reference for Chinese children and adolescents. Pediatric metabolic syndrome (MetS) and each risk factor for MetS were defined using the criteria for US adolescents. Definition of hyper-TC, LDL, and dyslipidemia for adults was applied as well. General linear model factor analysis and chi-square test were used to compare the difference in metabolic indicators among normal weight, overweight, and obese groups. Multiple logistic regression analysis was performed to estimate the odds ratio of metabolic abnormalities between obesity, overweight, and normal weight children, after adjustment for living area, family economic level, age, sex, and daily exercise time and TV watching time, as well as different dietary indices in the model.

RESULTSSignificant increases in blood lipids, glucose, and blood pressure were found among overweight and obese children as compared with their counterparts with normal weight. By applying WGOC-recommended BMI classification, the risks for hypertriglyceridemia, low HDL and dyslipidemia among overweight children were 1.9, 1.4, and 1.5 times, and was 3.3, 1.5, and 1.8 times among obese groups compared to their counterparts with normal weight after adjustment for age, sex, region, socioeconomic status, physical activity, and dietary intakes. The overweight and obese children (15-17.9 years) had a high-risk of developing hypertension, which was 2.3 and 2.9 times higher than their counterparts with normal weight. Above 90% obese adolescents had abdominal obesity, while less than 1% normal weight ones had abdominal obesity. No obese adolescents were free from any risk factors for MetS, while 36.9% of normal weight adolescents were from the risk factors. 83.3% obese boys and all obese girls had metabolic syndrome, while only 15.5% normal weight boys and 18.8% normal weight girls had metabolic syndrome. Four risk factors for metabolic syndrome were found in 8.3% obese boys while none in normal weight boys and girls. The prevalence of MetS among normal weight, overweight, and obesity groups was 1.5%, 18.3%, and 38.1% respectively.

CONCLUSIONThe cardiovascular disease (CVD) risk factors are clustered in obese Chinese children. Our observations strongly suggest that efforts should be made to prevent the onset of overweight and its associated diseases during early childhood.

OBJECTIVETo investigate the expression and relationship between HSP70 and caspase-3 in knee osteoarthritis.

METHODSForty adult SD rats were divided into experimental group and control group. Thirty rats in experimental group, anterior cruciate ligament transaction (ACLT) was cut off and partial meniscectomy of 1/3 inside incision were performed to reproduce knee osteoarthritis (KOA) model according to Hulth methos, and the other 10 rats was treated with nothing as control group. The rats were sent to the cage and free to move. At 1, 2 and 4 weeks later, the arthritis cartilage of femoral and tibial end were observed through immunohistochemistry staining and light microscope. Meanwhile, Mankin scale system was adopted for histomorphology evaluation.

RESULTSChanges of KOA such as hyperplastic synovium,erosion on the surface of cartilage and so on were found in experiment group, the expression of HSP70 was augmentation all the time, but the expression of caspase-3 was reduction 1 week later; no similar changes were found in control group. Mankin scale system showed that there were significant differences in the first week as compared with the second week and 4th week (both P < 0.01).

CONCLUSIONHeat shock protein inhibit the apoptosis of cartilage cells and protect the cartilage cells in knee osteoarthritis, the conservative treatment for clinical provide objective scientific basis.

OBJECTIVESTo describe the microbiology, antimicrobial susceptibility of patients proven prosthetic joint infection (PJI) after primary total knee arthroplasty (TKA)and to provide reference for the diagnosis and treatment of this complication.

METHODSThe medical data of the patients with infected knee arthroplasty, who were managed with revision surgery between January 1995 to December 2011 were reviewed. Twenty-nine cases were identified and majority of the patients were female (23/29). Diagnosis of PJI after primary TKA was between 1 week and 10 years (average 24.3 months). The microbiology and antimicrobial susceptibility were analyzed.

RESULTThe overall positive rate of cultures was 65.5% (19/29). The most common organisms identified were Coagulase-negative Staphylococcus (CNS) (7/19) and Staphylococcus Aureus (SA) (5/19). Rare pathogens of Mycobacterium (2/19) and fungi (1/19) were also identified. Vancomycin was the most effective antibiotics with overall sensitivity rates of 100%.Resistant and rare pathogens were all in type IV infection.

CONCLUSIONSGram-positive bacterias are the main pathogen, resistant and rare pathogens should be payed attention to. Antibiotic treatment for infected TKA should be based on the results of drug susceptibility. Vancomycin allows infected knee arthroplasties before the result.
