ABSTRACT
Objective:To report two cases of post-transplantation lymphoproliferative disorders (PTLD) after kidney transplantation in children and review the literature, and to improve clinicians' understanding of PTLD in children.Methods:The clinical data of two children with PTLD admitted to the Children's Hospital of Fudan University were collected and analyzed. The PTLD-related literature of PubMed, Embase, Web of Science, Scopus, Cochrane Library, Wanfang, CNKI, Weipu Database and China Biomedical Literature Service System from the establishment of the database to January 2020 were collected for literature review. Multivariate logistic regression analysis method was used to analyze the influencing factors of prognostic in children with PTLD.Results:Both of the patients had negative Epstein-Barr virus (EBV) and Cytomegalovirus (CMV) before transplantation and anti-thymocyte immunoglobulin (ATG) were induced during transplantation. PTLD in case 1 and case 2 was diagnosed at 3 and 12 months after transplantation, respectively, with positive EBV and CMV serological reaction. The pathological diagnosis was monomorphic PTLD in case 1 and the case 2 was clinically considered as non-hodgkin lymphoma. They all received thrapies of immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. PTLD was relieved and graft function was normal in 2 cases, while case 1 died two and half years after transplantation due to intracranial fungal infection. According to the analysis of 56 children (including 2 cases in this study) with PTLD from the literature review, the median time of PTLD from transplantation was 41.8 months. The initial involved organs were digestive tract [17 cases (30.4%)], respiratory system [8 cases (14.3%)], nervous system [7 cases (12.5%)] and pharyngeal lymph ring [7 cases (12.5%)], respectively. The main pathologic type of PTLD was monomorphic [34 cases (60.8%)]. Fifty-six cases were all positive in EBV serological reaction when PTLD was diagnosed. The treatment included immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. Forty-eight cases of PTLD were relieved, while 8 cases lost graft function. Eleven cases died, including 3 cases due to infection and the other 8 cases due to PTLD. Multivariate logistic regression showed that monomorphic PTLD was a risk factor of death for PTLD children ( OR=21.616, 95% CI 1.007-464.107, P=0.049). Conclusions:PTLD in children with kidney transplantation is mostly associated with EBV infection, and the clinical manifestations are diverse. Monomorphic PTLD has a poor prognosis and high mortality.
ABSTRACT
Objective@#To evaluate the quality of life (QOL) of children with uremia who underwent renal replacement therapy (RRT) and identify the influencing factors for QOL in order to improve the QOL of children with uremia.@*Methods@#Children with ESRD who underwent dialysis or kidney transplantation (KT) at Children's Hospital of Fudan University between November 2016 and October 2017 were enrolled. The children and/or their parents completed and returned the Pediatric QOL Inventory Measurement Models (PedsQLTM) 4.0 questionnaire. Moreover, the clinical data of these children were collected. According to the way of RRT, children were divided into dialysis group and KT group. The differences of scores between two groups were compared. Multiple linear regression analysis was used to analyze the factors affecting the QOL of children.@*Results@#A total of 79 children undergoing RRT were enrolled. Among them, 48 cases in the dialysis group and 31 cases in the KT group. For children in KT group, the total PedsQL scores of child-self and parent-proxy assessment were higher than those in dialysis group (P<0.05). The total scores for the QOL of child-self and parent-proxy assessment were roughly the same for KT children (P>0.05). The total scores for the QOL of child-self and parent-proxy assessment were different for dialysis children (P=0.05). Short stature (height<3th percentile) and elevated left ventricular mass index (LVMI) were the independent influencing factors for the QOL of child-self and parent-proxy assessment in children undergoing KT, respectively (B=12.162, t=2.681, P<0.05; B=-0.240, t=-4.276, P<0.01).@*Conclusions@#QOL was higher in children undergoing KT than those on dialysis. Short stature and elevated LVMI were the independent influencing factors for QOL in children undergoing KT.
ABSTRACT
PURPOSE: The characteristic expression of DNA damage response proteins in familial breast cancers with BRCA1, BRCA2, or non-BRCA1/2 mutations has not been analyzed in Chinese patients. Our study aimed to assess the differential expression of microcephalin 1 (BRIT1), ATM serine/threonine kinase (ATM), checkpoint kinase 2 (CHEK2), BRCA1, RAD51 recombinase (RAD51), and poly (ADP-ribose) polymerase 1 (PARP-1) and establish the profile of Chinese familial breast cancers with different mutation status. METHODS: We constructed five tissue microarrays from 183 familial breast cancer patients (31 with BRCA1 mutations; 14 with BRCA2 mutations, and 138 with non-BRCA1/2 mutations). The DNA response and repair markers used for immunohistochemistry analysis included BRIT1, ATM, CHEK2, BRCA1, RAD51, and PARP-1. The expressions of these proteins were analyzed in BRCA1/2 mutated tumors. The association between pathologic characteristics with BRCA1/2 mutation status was also analyzed. RESULTS: In familial breast cancer patients, BRCA1 mutated tumors were more frequent with high nuclear grade, estrogen receptor/progesterone receptor/human epidermal growth factor receptor 2 negative, low Ki-67, and positive CK5/6. BRCA1 mutated tumors had lower CHEK2 and higher cytoplasmic BRIT1 expression than BRCA2 and non-BRCA1/2 mutation tumors. BRCA2-associated tumors showed higher CHEK2 and cytoplasmic RAD51 expression than those in other groups. Nuclear PARP-1 expression in BRCA1/2-associated tumors was significantly higher than in non-BRCA1/2 mutation tumors. Moreover, we found quite a few of negative PARP-1 expression cases in BRCA1/2 mutated groups. CONCLUSION: The clinicopathologic findings of BRCA1-associated Chinese familial breast cancers were similar to the results of other studies. Chinese familial breast cancer patients with BRCA1/2 mutations might have distinctive expression of different DNA damage response proteins. The reduced expression of PARP-1 in Chinese BRCA1/2 mutated breast cancer patients could influence the therapeutic outcome of PARP-1 inhibitors.

Objective@#To investigate the clinicopathologic features and differential diagnosis of breast lymphoma in core needle biopsy.@*Methods@#Seventy-two cases of breast lymphoma in core needle biopsy between 2011 and 2016 were extracted from the pathology database of Fudan University Shanghai Cancer Center. The clinicopathologic features were analyzed. The histological diagnosis of the tumors was based on the WHO classifications of tumors of hematopoietic and lymphoid tissues. Immunohistochemistry and molecular methods were performed to detect related antigens and genes.@*Results@#Seventy-one patients were female and one was male. The median age was 54 years. The tumors were located in the right breast in 32 (44.4%) patients and in the left breast in 40 (55.6%) patients. Seven patients had a previous history of lymphoma. Most of the cases presented as a single and painless breast mass. Sixty-three patients received systemic treatment, and nine patients received systemic therapy after excision. The common morphological feature was that single tumor cells infiltrated the stroma, without cohesiveness between tumor cells, and lacking glandular or nested epithelioid structures. The normal ductal and lobular structures of the mammary gland were typically preserved. The tumor cells in some cases were distributed in single rows, and should be differentiated from invasive carcinoma. All cases were positive for LCA, negative for CK. Sixty-eight cases were classified as B-cell lymphoma, including 63 cases (87.5%) of diffuse large B-cell lymphoma (DLBCL; including 3 cases of EBV-positive DLBCL and 60 cases of DLBCL, NOS), two cases of Burkitt lymphoma, one case of mantle cell lymphoma, one case of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue and one case of precursor B lymphoblastic leukemia/lymphoma. The remaining cases included two peripheral T-cell lymphoma (NOS), one extranodal NK/T cell lymphoma, nasal type and one myeloid sarcoma. In 63 cases of DLBCL, 22 cases (34.9%) expressed germinal center B-cell-like (GCB) phenotype and 41 cases (65.1%) showed non-germinal center B-cell-like (non-GCB) phenotype.@*Conclusions@#Core needle biopsy could be the preferred method for diagnosis of breast lymphoma. Diffuse large B-cell lymphoma is the most common histologic type of breast lymphoma, and non-GCB subtype is more frequent than GCB subtype.

ABSTRACT
Objective:Imatinib is extensively used as a first-line therapeutic agent for patients with chronic myeloid leukemia (CML) at the chronic phase (CP). Although CML patients undergoing imatinib treatment are enrolled mainly in the Glivec International Patient Assistance Program (GIPAP) in China since 2003, limited data have been reported on the long-term outcome of these patients. This study aims to compare the treatment response and prognosis of CML-CP patients who received different treatments from January 2003 to December 2013 in the First Affiliated Hospital of Nanchang University. Methods:A total of 295 patients were enrolled, includ-ing 185, 30, 50, and 30 patients for imatinib, interferon-alpha (IFN-α) plus Ara-C, hydroxycarbamide (HU), or allogeneic hematopoietic stem cell transplantation (Allo-HSCT) treatments, respectively. Results:Patients in imatinib and Allo-HSCT groups achieved excellent complete hematologic remission (CHR) (i.e., 96.7%vs. 96.7%), complete cytogenetic response (CCyR) (i.e., 89.7%vs. 93.3%), and com-plete molecular remission (CMoR) (i.e., 49.7%vs. 83.3%, P=0.001). However, significantly low rates of CHR, CCyR, McyR, and CMoR were observed in IFN-αand HU groups. Moreover, patients from imatinib group showed longer overall survival (OS) time than patients from other groups (P<0.001), even patients in Allo-HSCT group (10-year OS, 89.0%vs. 67.0%, P<0.001) because of high risk of Allo-HSCT-related complication. Multivariate analysis showed that receiving imatinib treatment (HR=5.267, 95%CI:1.054-1.940, P=0.022) and achieving CCyR (HR=9.541, 95%CI:1.692-10.513, P=0.002) were independent predictors for OS. Conclusion:Imatinib treatment may be an optimal first-line choice for Chinese patients with CML-CP who have not received any previous treatments.

Objective To explore the resistance and molecular mechanisms underlying the anticancer activity of daunorubicin in CD34 +acute myeloid leukemia(AML) cells. Methods CD34 +AML cell lines(KG1a and Kasu-mi-1)were used as objectives, and CD34 -AML cell line U937 was used as positive control. Western blot analysis was used to examine the protein expression of Bcl-2 and Bax in CD34 +AML and CD34 -AML cell lines incubated with/without daunorubicin to compare the sensitivity of CD34 +AML and CD34 -AML cells to daunorubicin. SiRNA against Bcl-2 was used in KG1a and Kasumi-1 cells and examined the effect on cell viability by MTT assay. Results Western blot analysis showed that Bcl-2 protein levels in CD34 +AML cells appeared to be significantly higher than in CD34 -AML cells. Western blot analysis showed that treatment with 0.4 μg/ml daunorubicin for 48 h caused down-regulation of Bcl-2 only in CD34 -AML cells,but not in CD34 +AML cells. Suppression of Bcl-2 with siRNA increased the susceptibility of KG1a and Kasumi-1 to daunorubicin. Conclusion CD34 +AML cell lines ex-press higher levels of Bcl-2 protein. Daunorubicin fails to down-regulate the high Bcl-2 protein levels in CD34 +AML cells. Suppression of Bcl-2 with siRNA increases the susceptibility of KG1a and Kasumi-1 to daunorubicin. The high Bcl-2 protein levels in CD34 +AML cells may be involved in the insensitivity to daunorubicin.
ABSTRACT
Objective To assess the prognosis and effect on renal function of pediatric urolithiasis caused by melamine-contaminated milk powder (PUMMP) in a long-term follow-up.Methods One hundred and two of 8335 children (≤ 6-year-old) with history of consuming melamine-contaminated milk powder screened in our hospital were followed up for eighteen months after diagnosis. Urinary system ultrasonography, urinalysis, urinary microprotein profiles [microalbumin (ALBU), immunoglobulin G (IgG), and N-acetyl-β-D-glucosidase (NAG)], urinary melamine and cyanuric acid were examined in the first visit and at the end of follow-up. Results Follow-up was completed in 91 children and the stone was excreted in 82 children (90.1%).Stones less than 5 mm in diameter were most vulnerable to discharge, and stones larger than 10 mm could not be expelled without interventions. At the end of follow-up, no melamine or cyanuric acid was found in the urine samples of 74 patients. Urinalysis showed that incidences of proteinuria, microscopic hematuria and leukocyturia were 0%, 5.1% and 2.0%, which were significant different from those in the first visit (Pproteinutria=0.123, Phemnatuna=0.038 and Pleukocyhuris=0.005).Urinary microprotein profiles revealed that some children whose urinalysis was normal still presented glomerular and renal tubular injury and the abnormal rates were 8.8% and 12.1%respectively. The glomerular injury was mainly related to persistent stone, male and younger.Conclusions 90.1% of children with PUMMP passes urinary stones at the end of follow-up.Stone size is the major risk factor of discharge. No melamine or cyanuric acid is found in the urine of children. After eighteen months, glomerular and renal tubular injury is still found in some patients. Further follow-up is necessary.
ABSTRACT
To investigate the combined effect of human recombinant soluble TNF-related apoptosis induced ligand (hrsTRAIL) with Ara-C or alone on HL-60 leukemia cell lines and its mechanism, human leukemia cell lines HL-60 were cultured in vitro. HL-60 cells were divided into 5 groups: control group, Ara-C group, rsTRAIL group, Ara-C + rsTRAIL simultaneously given group, Ara-C + rsTRAIL tandem given group (Ara-C followed by rsTRAIL group). The cytotoxic effect was measured by MTT assay; cell apoptosis rate was determined by flow cytometry after Annexin V/PI staining; the expression level of DR5 on surface of HL-60 cells treated with Ara-C at different concentrations for 24 hours was determined by flow cytometry. The expression level of DR5 on surface of HL-60 cells and caspase-8 activity in HL-60 cells of rsTRAIL group and Ara-C + rsTRAIL tandem group was determined by flow cytometry. The result showed that rsTRAIL could inhibit the proliferation of HL-60 cells and induce apoptosis of HL-60 cells in a concentration-dependent manner. The apoptosis rate of HL-60 cells in Ara-C + rsTRAIL tandem given group was higher than that in Ara-C + rsTRAIL simultaneously given group, the expression level of DR5 on surface of HL-60 cells and intracellular activity of caspase-8 in Ara-C + rsTRAIL tandem given group were higher than those in rsTRAIL group. When HL-60 cells treated with 5 and 10 mg/L of Ara-C for 24 hours, the expression level of DR5 on surface of HL-60 cells was higher than that in control group. It is concluded that rsTRAIL can inhibit the proliferation of HL-60 cells, and induce apoptosis of HL-60 cells. Ara-C can upregulate DR5 expression on the surface of HL-60 cells and enhance the effect of rsTRAIL-inducing apoptosis. Tandem treatment of HL-60 cells with Ara-C followed by rsTRAIL induce more apoptosis than that of co-treatment with rsTRAIL and Ara-C. Ara-C and rsTRAIL has a synergistic inhibitory effect on growth of HL-60 cells. The mechanism may correlate with up-regulation of the expression level of DR5 and/or caspase-8 in HL-60 cells by Ara-C.

<p><b>OBJECTIVE</b>To analyze the clinical features, renal damage and prognosis of primary vesicoureteric reflux (VUR) in children, hoping to give more attention to early recognition and treatment of the disease.</p><p><b>METHODS</b>Between June 1995 and December 2006, 974 patient were admitted in our hospital because of urinary tract infection (UTI), 139 primary VUR children were enrolled in the retrospective study. VUR grades, renal scar development, renal ultrasound and urinalysis were evaluated.</p><p><b>RESULTS</b>The incidence of VUR in UTI children was 14.3% (139/974), however, the incidence in infants and toddlers (younger than two years of age) was 17.2% (79/458), which was greatly higher than that in school children. Of the 139 children, 79(56.8%) were younger than two years and the number of boys was much larger than that of girls (P = 0.001). Bilateral reflux was found in 69 cases, unilateral in 70 cases; the percentages of mild reflux (grade I-II) was 19.7% (41/208), moderate reflux (grade III) was 35.6% (74/208), severe reflux (grade IV-V) was 44.7% (93/208). Dimercaptosuccinic acid (DMSA) scanning was performed for 135 patients, and renal scar was found in 37% (50/135), and the rate of scar in infants was the highest (42.4%), and 30 (60%) patients with renal scar were younger than two years of age. Among them five patients were found to have renal scar during the follow up period, four of them were younger than two years. The rate of renal scar in moderate and severe reflux was much higher than that in mild reflux cases, the risk of occurring renal scar would increase with its severity of reflux (P < 0.001). The sensitivity and specificity of renal ultrasound in suggesting VUR were 24.8% and 94.3%, respectively. The positive outcome of urinary N-acetyl-beta-glucosaminidase was a bit high, but there were no associations between renal scar and urinary microprotein (P > 0.05). Thirty-one cases were followed up for long time (> 1 year); and 90% of urinary infection was controlled and in 44.4% of patients VUR disappeared with medical treatment. No child had decreasing renal function in follow-up period.</p><p><b>CONCLUSION</b>Children with primary VUR need early diagnosis and treatment. Insisting on normal therapy and long-term follow-up will protect renal function effectively.</p>

Objective To examine the expression of angiopoietin-like protein(ANGPTL)3 in kidneys from children with primary nephrotic syndrome. Methods Immunohistochemistry for ANGPTL3 was performed in kidney biopsies from patients with nephrotic syndrome or hematuria, including MCD (n=31), MN(n=6), FSGS (n=6), TBMN (n=10), IgA nephropathy (IgAN) with mesangial proliferation (n=16). Normal renal tissue of 2 cases with nephrectomy for tumor were used as control. According to the episode, four groups were divided ("12 months"). The expression was quantitatively examined with IMS color image analysis system, using positive index (PI) as sediment degree of ANGPTL3 in glomeruli or tubules. Immunofluorescence for ANGPTL3 co-labeling with WT1 and perlecan was applied to show the distribution of ANGPTL3. Results (1) The PI levels of ANGPTL3 in glomeruli of MCD(7.49?1.96) and MN (6.27?0.98) were significantly higher than those of TBMN (0.02?0.001), FSGS (3.14?0.49) or normal control(0.02?0.001) respectively (all P
