This reform established a set of curriculum system, teaching methods and evaluation methods to strengthen the cultivation of medical students' post competency, and achieved the goal of improving the quality of clinical medical personnel training in local medical colleges.
RESUMEN
Objective:To evaluate the treatment efficacy of children with T-cell acute lymphoblastic leukemia (T-ALL) and to explore the prognostic risk factors.Methods:The clinical and laboratory data of children with newly diagnosed T-ALL in Children's Hospital of Fudan University and Children's Hospital of Shanghai from January 2002 to December 2014 were retrospectively analyzed and compared with children with newly diagnosed B-cell acute lymphoblastic leukemia (B-ALL) in the same period. The treatment protocols were based on the combination of the Berlin-Frankfurt-Münster (BFM)-ALL regimen with chemotherapy. The treatment response and infection of the children were observed. Cox proportional hazard regression model single-factor and multifactor analysis were used to evaluate the prognostic factors.Results:Seventy-one children with T-ALL and 333 children with B-ALL were enrolled. The clinical features including gender, age, central nervous system leukemia as well as the white blood cell count at first diagnosis were significantly different between the two groups (all P < 0.05). The prednisone good response rates of children with T-ALL were lower than that of B-ALL [78.9% (56/71) vs. 93.4% (311/333), P < 0.01], and the complete remission rates were lower than that of [94.4% (67/71) vs. 99.1% (330/333), P= 0.023]. By the end of follow-up, the relapse rates of children with T-ALL and B-ALL were 20.9% (14/67) and 16.4% (54/330) ( P= 0.369). The children with T-ALL had a shorter time to relapse compared with children with B-ALL [64.3% (9/14) vs. 35.2% (19/54), P= 0.049]. The 5-year overall survival (OS) rates of children with T-ALL and B-ALL were (62.1±6.4)% and (81.3±2.4)% (P < 0.05), and the 5-year event free survival (EFS) rates were (61.0±6.3)% and (71.0±2.7)% (P < 0.05). There was no significant difference in OS and EFS among pro/pre T-ALL, cortical T-ALL and mature T-ALL (both P > 0.05). The difference of EFS curves between children with early T-precursor (ETP)-ALL and non-ETP ALL was statistically significant ( P= 0.044). The most common infection site was respiratory tract [63.9% (186/291)], and the gram-negative bacteria accounted for 43.5% (20/46). Cox univariate analysis showed that prednisone poor response, bone marrow non-remission on day 33 of induction-therapy, relapse and sepsis were prognostic risk factors for children with T-ALL (all P < 0.05), and Cox multivariate analysis showed that the latter three were independent prognostic risk factors (all P < 0.05). Conclusions:The prognosis of children with T-ALL is worse than children with B-ALL, and T-ALL patients are prone to early relapse. The EFS of children with ETP-ALL is poor. Non-remission at the end of induction-therapy, relapse and sepsis are independent risk factors for prognosis.
RESUMEN
Objective@#To evaluate the expression of p-AKT and p-mTOR, the key proteins in PI3K/AKT/mTOR pathway in pediatric Burkitt lymphoma (BL), and to investigate the clinical and prognostic significance.@*Methods@#Fifty-eight cases of pediatric BL and thirty cases of reactive hyperplastic lymphadenitis (RH) were collected at Children′s Hospital of Fudan University from September 2011 to July 2018. Paraffin sections of tissues were immune stained for p-AKT and p-mTOR, and the expression was assessed and correlated with the clinical features and prognosis.@*Results@#A total of 58 cases were diagnosed and 6 cases lost the follow-up. Of the remaining 52 BL patients including 43 males and 9 females, the median age was 5 years (range: 2 to 14 years). Regarding to the correlation between the two biomarkers, Spearman test showed that p-mTOR was positively associated with the expression of p-AKT (r=0.759, P<0.001). Of all BL patients, the positive rates of p-AKT and p-mTOR were 62.1% (36/58) and 60.3%(35/58) respectively, both significantly higher than control group (P=0.011, P=0.035 respectively). The presence of p-AKT was significantly associated with higher lactate dehydrogenase (LDH≥573 IU/L) level in patients of the disease (P=0.006), while p-mTOR was increased both in the higher LDH and lower ratio of albumin to globulin (A/G) group (P=0.006, P=0.034 respectively). Expression of p-AKT and p-mTOR did not show any statistical correlation with sex, age, St.jude stage, tumor size, B-symptom present or not, number of extra-nodal sites or international prognostic index (IPI) (P>0.05). Fifty-two patients had a median follow-up of 40 months (range: 5-87 months). Univariate analysis showed that p-AKT expression was significant in predicting both inferior OS (5-year estimate, 72.7% vs. 94.7%, χ2=4.123, P=0.042) and PFS (5-year estimate, 66.7% vs. 94.7%, χ2=5.822, P=0.016). The 5-year OS rate was 71.0% (22/31) for the p-mTOR positive cohort of patients compared to 95.2% (17/21) for p-mTOR negative group (χ2=4.881, P=0.027); however, there was no statistical significance in 5-year PFS rate (P>0.05). Especially, the 5-year OS and PFS rate of p-AKT/p-mTOR double-positive group were significantly lower than negative control group (including absence of single p-AKT or p-mTOR expression, and absence of both) (OS: 69.0% vs. 95.7%, χ2=6.285, P=0.012; PFS: 65.5% vs. 91.3%, χ2=5.405, P=0.020). The results of multivariate COX proportional risk regression analysis indicated that p-AKT/p-mTOR double-positive, higher LDH and IPI score 3-5 were independent prognostic factors for both OS and PFS, and the bulky tumor (>10 cm) for PFS of pediatric BL.@*Conclusion@#The expression of p-AKT and p-mTOR may be a potential reference for diagnosis and the independent prognostic indicators of pediatric BL.

RESUMEN
Objective To investigate the efficacy and prognostic risk factors of ALL-R-2003 protocol in the treatment of relapsed childhood relapsed acute lymphoblastic leukemia (ALL) in single center. Methods A retrospective study of clinical data of 51 children with relapsed ALL from January 2004 to December 2014 was performed by using SPSS version 19.0 statistical software for statistical analysis. Results The median age at initial diagnosis of 51 patients was 5.5 years (range, 0.8-13.4 years). The median time from initial diagnosis to relapse was 25 months (range, 3-68 months) and follow-up time was 39 months (range, 3-116 months). The relapse rate in the standard-risk, intermediate-risk and the high-risk groups were 27.5 % (14/51), 29.4 %(15/51) and 43.1 % (22/51), respectively. The probability of 3-year overall survival (pOS) after relapse was (18.8±5.9)%and the probability of event free survival (pEFS) was (16.2±5.8)%. The 3-year pOS in very early relapse, early relapse and late relapse were 0, (11.7 ±7.7) % and (51.7 ±14.8) %, respectively (P= 0.000). There was no statistical difference in survival rate of different immunophenotype groups and sites of relapse (P> 0.05). The 3-year pOS of group S1, S2, S3, S4 were (50.0±35.4) %, (39.9±1.3) %, (10.0±9.5) % and 0, respectively (P=0.000). The 3-year pOS of bcr-abl and MLL gene positive groups were (25.0±21.7) %and 0, respectively, with no statistically significance compared with the negtive group [(24.1±12.0)%] (P>0.05). The 3-year pOS rates of children with bone marrow transplantation and without transplantation were (40.0 ±15.5) %and (13.0 ±5.9) % respectively (P= 0.038). Conclusions The children who in high risk group at initial diagnose are easily to meet earlier relapse and poorer prognosis. The survival period after relapse of bcr-abl or MLL gene positive cases is very short. Bone marrow transplantation can improve survival rate. Risk group at initial diagnose, relapse time and transplantation are the main factors influencing prognosis, and the relapse time and transplantation are the independent prognostic factors for relapsed childhood ALL.

Objective To construct and implement the nursing quality information feedback system based on QUACERS model and control theory, and discuss its application effect and the problems that should be paid attention to and to provide operational cases and practical basis for nursing quality management. Methods Through literature review and expert consultation, the framework and content of nursing quality information feedback system were set up and implemented. The changes of the nursing quality and the repeated occurrence of nursing problems were evaluated before (2013) and after (2015) the implementation of this project. And in December 2015, a self-made questionnaire was conducted among the nurses in the hospital to evaluate the importance of the feedback and it′s effect of improving the nursing quality. And evaluate the timeliness and effectiveness of different feedback forms. Results 1 120 and 1 136 nurses were followed-up in 2013 and 2015 respectively. The scores of human resource management, clinical nursing service and nursing safety management were higher than before, and the repeated occurrence of nursing problems was lower than before. A total of 450 questionnaires were distributed, 438 copies were collected, the effective recovery rate was 97.33%. Ratings for the importance of each item was from 3.37 to 4.57. Ratings for the effect of improving the quality of care was 3.79 to 4.39. The percentage of quality information received by nurses was more than 95%, and the average score of feedback timeliness was 4.29 to 4.53. Conclusions Quality information feedback system based on QUACERS model can cover multiple dimensions of quality management, and it was conducive to obtaining comprehensive information;Combined with multiple feedback forms can improve the effect of information feedback.
RESUMEN
Background and purpose: L-asparaginase (L-Asp) is an important drug in the treatment of childhood lymphoid neoplasms at present, but a lot of adverse reactions of L-Asp were observed. Pegasparaginase (PEG-Asp) is available in China in recent years. This study aimed to explore efifcacy and side-effect of PEG-Asp as ifrst-line treatment in childhood acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Methods:A total number of 211 ALL or LBL patients were treated with CCLG 2008 or BFM-90 protocol with PEG-Asp or L-Asp between Apr. 2008 and Mar. 2013;42 patients, among whom, were 35 ALL patients and 7 LBL patients, were treated with PEG-Asp as ifrst-line treatment;169 patients were treated with L-Asp as ifrst-line treatment (including 53 patients treated with L-Asp during induction protocol; with PEG-Asp during consolidate protocol). The clinical outcome and adverse reaction of PEG-Asp with L-Asp were observe and compared. Results: There were 35 ALL patients in PEG-Asp ifrst-line treatment group and the complete remission rate after 1 course of PEG-Asp was 97.1%,however, which was 83.3%of high risk ALL patients. The complete remission rate of 7 LBL patients of PEG-Asp ifrst-line treatment group was 57.1%. There was no signiifcant difference between 2 groups (P>0.05). Thirty-four patients relapsed including 5 patients of PEG-Asp ifrst-line treatment group, 16 patients of L-Asp ifrst-line treatment group and 13 patients treated with L-Asp during induction protocol and with PEG-Asp during consolidate protocol. Thirty-one patients died including 3, 18, 10 patients in 3 groups respectively. Twenty-two patients died of relapse, 4 died without remission, 5 died of complications. There was also no signiifcant difference between 2 groups (P>0.05). The incidence rates of adverse reactions were 47.6% and 63.3% respectively. Anaphylaxis, liver functions abnormalities, blood coagulation abnormalities, gastrointestinal reaction, hyperglycemia and pancreatitis were common in our patients. The incidence rate of anaphylaxis in PEG-Asp as ifrst-line treatment group was lower than other groups (P=0.03). But there was no signiifcant difference been observed in the incidence of other adverse reaction. Conclusion: The short-term efifcacy of PEG-Asp as the ifrst-line treatment in childhood leukemia and lymphoma was satisfactory and the incidence rate of anaphylaxis was lower. However, we will still pay much attention to adverse reaction monitoring of PEG-Asp.
