OBJECTIVE@#To investigate the effect of modified LMB 89± rituximab regimen on long-term clinical benefit for patients with Burkitt lymphoma.@*METHODS@#Clinical data of 43 patients with Burkitt lymphoma were collected and retrospectively analyzed in the period from July 2006 to October 2017. Forty-three patients were divided into 2 groups, including Hyper-CVAD regimen, R-EPOCD regimen or VDCLP regimen treated group as control (20 patients) and modified regimen group with modified LMB 89±rituximab regimen (23 patients); the event-free survival (EFS) rate, overall survival (OS) rate, cumulative incidence of relapse (CIR), non-relapse mortality rate (NRM) and adverse reaction incidence of 2 groups were compared. At the same time, the efficacy analysis for patients of modified regimen group was performed according to age and using rituximab or no.@*RESULTS@#The EFS rate and OS rate of modified regimen group were significantly higher than those of control group (P＜0.05). The CRR rate and NRM rate of modified regimen group were significantly lower than those of control group (P＜0.05). The EFS rate and OS rate of patients for ＜40 years old were significantly higher than those of patients for ≥40 years old in modified regimen group (P＜0.05). The EFS rate and OS rate of patients with rituximab were significantly higher than those of patients without rituximab in modified regimen group (P＜0.05). There was no significant difference in the adverse reaction incidence between 2 groups (P＞0.05).@*CONCLUSION@#Modified LMB 89± rituximab regimen in the treatment of patients with Burkitt lymphoma can efficiently prolong survival time and shows the better safety; and the remigen combined with rituximab is more helpful to improve the clinical prognosis and show the better clinical effects for the patients≤40 years old.

Curative Efficacy of First Generation TKI in the Treatment of CML-CP Combined with vPh and Analysis of Its Genetic Characteristics / 中国实验血液学杂志

OBJECTIVE@#To investigate the curative efficacy of first generation TKI in the treatment of CML-CP combined with vPh and genetic characteristics.@*METHODS@#60 patients with CML-CP combined with vPh from January 2010 to May 2017 in the First Affiliated Hospital of Kunming Medical University were chosen as CML-CP-vPh group, and 107 patients with CML-CP combined with typical Ph chromosome at the same time were chosen as control group. The patients in two groups were treated with imatinib; The curative efficacy, karyotype and FISH signal type were compared between 2 groups, and the factors influencing long-term survival of patients were analyzed by Cox risk model.@*RESULTS@#There was no significant difference in the demographic and hematological baseline data between 2 groups (P＞0.05), and there was no significant difference in the incidence of drug-resistance between 2 groups (P＞0.05). The incidence of primary drug-resistance and primary hematological drug-resistance in the CML-CP-vPh group were significantly higher than that in control group (P＜0.05). There was no significant difference in the accumulative CCyR rate, accumulative MMR rate, OS and EFS between 2 groups (P＞0.05). Multivariate Cox model analysis showed that vPh not correlated with OS and EFS of patients with CML-CP (P＞0.05). The factors influencing OS in CML-vPh patients included high risk of Sokal scores, peripheral blood basophils proportion ≥10%, BCR-ABL in 3 months after treatment＜10%, achieviag CCyR in 6 months after treatment and achieviag MMR in 12 months after treatment (P＜0.05). The factors influencing EFS included BCR-ABL＜10% in 3 months after treatment and achieving MMR in 12 months after treatment (P＜0.05). The regions with high frequency of heterotopic involvement included 12q1, 12q2 [9 cases (15.00%)] and 1p3 [8 cases (13.33%)]. The percentage of 2G2R1Y, 1G1R2F, 1G2R1Y, 2G1R1Y and 1G1R1Y in FISH signal types were 73.33%, 10.00%, 1.67%, 1.67% and 1.67% respectively.@*CONCLUSION@#Patients with CML-CP combined with vPh possess higher primary drug-resistance rate and primary hematological drug-resistance rate for the first generation TKI, while second-generation TKI can efficiently improve long-term survival, its efficacy is similar to efficacy for patients with typical Ph chromosomes. CML-CP combined with vPh does not display special demographic and hematological characteristics. The main involved regions of heterotopic variants include 12q1, 12q2 and 1p3, while 2G2R1Y type is the most common type of FISH signal.

Mechanisms of inhibition of invasion and metastasis of nasopharyngeal carcinoma cells by neferine through its influence on microRNAs / 药学学报

This study was designed to investigate the inhibitory effect and mechanism of neferine (Nef) on invasion and metastasis of nasopharyngeal carcinoma cells (NPC). The viability of CNE-1 and 5-8F cells was detected by CCK-8 assay after treatment with different concentrations of Nef. The effects of Nef on cell migration and invasion were detected by the scratch test and Transwell assay. Western blot analysis was used to detect the effects of Nef on levels of epithelial-mesenchymal transition (EMT)-associated proteins and transcription factors. The differentially expressed gene profiles between control group and Nef group were analyzed by microRNA microarray, combined with bioinformation analysis. It was observed that 30 μmol·L-1 Nef had no significant effect on the viability of CNE-1 and 5-8F cells. Western blot assay showed that the expression level of neurotroponin cadherin (N-cadherin) and vimentin decreased after treatment with Nef, while the expression of epithelial cadherin (E-cadherin) increased. The expression of transcription factors including Twist, Snail, and Slug exhibited no significant difference. Results of the microRNA microarray suggest that 10 microRNAs showed significant differences when compared with the control group. Bioinformatics analysis showed that hsa-let-7c-5p and hsa-microRNA-423-5p targeted the same downstream genes: small integral membrane protein 3 (SMIM3) and nerve growth factor (NGF). Overexpression of hsa-let-7c-5p and hsa-miR-423-5p promoted the invasion and migration ability of 5-8F cells and decreased the expression of SMIM3 and NGF. The results from this study suggest that Nef may inhibit the invasion and metastasis of NPC cells by inhibiting the expression of hsa-let-7c-5p and hsa-miR-423-5p followed by the upregulation of SMIM3 and NGF; thus, regulating the expression of EMT-associated proteins. Our data have provided experimental evidence for the inhibition of tumor invasion and metastasis by Nef.

Assessing for Mood and Anxiety Disorders in Parents of Clinically-Referred Children: Laying the Foundation for a Family-Based Approach to Mental Health in Singapore

INTRODUCTION@#Family history of psychopathology is a risk factor for mood and anxiety disorders in children, but little is known about rates of parental psychopathology among treatment-seeking youth with affective disorders in the Asia Pacific region. This study examined patterns of emotional and behavioural problems in parents of clinically-referred youth in Singapore. We hypothesised that parents would have higher rates of affective disorders compared to the Singapore national prevalence rate of 12%.@*MATERIALS AND METHODS@#In this cross-sectional study, 47 families were recruited from affective disorders and community-based psychiatry programmes run by a tertiary child psychiatry clinic. All children had a confirmed primary clinical diagnosis of depression or an anxiety disorder. Parents completed the Mini International Neuropsychiatric Interview (MINI) to assess for lifetime mood and anxiety disorders. They also completed the Adult Self Report (ASR) and Adult Behavior Checklist (ABCL) to assess current internalising and externalising symptoms.@*RESULTS@#Consistent with our hypothesis, 38.5% of mothers and 10.5% of fathers reported a lifetime mood and anxiety disorder. Nearly 1/3 of mothers had clinical/subclinical scores on current internalising and externalising problems. A similar pattern was found for internalising problems among fathers, with a slightly lower rate of clinical/subclinical externalising problems.@*CONCLUSION@#Our findings are consistent with previous overseas studies showing elevated rates of affective disorders among parents - particularly mothers - of children seeking outpatient psychiatric care. Routine screening in this population may help to close the current treatment gap for adults with mood and anxiety disorders.

Effect of TGF-β1 on the proliferation of lymphoma cells induced by M2 macrophages / 中国比较医学杂志

Objective To investigate the effect of TGF-β1 on the proliferation of lymphoma cells induced by M2 macrophages. Methods TGF-β1 was used to treat Jiyoye lymphoma cells, and MTT was used to determine the cell proliferation. Lymphoma cells were treated with M2 macrophage culture liquid supernatant and TGF-β1. MTT assay was used to assess the lymphoma cell proliferation, Transwell assay was used to assess the cell migration and invasion, and Western blot was perfomed to determine the levels of MMP-2, MMP-9, PCNA and Ki-67 proteins. Results The lymphoma cells after TGF-α treatment showed that the proliferation ability, the number of invaded cells and the number of migrated cells, and the levels of MMP-2, MMP-9, PCNA and Ki-67 were significantly decreased, compared with the untreated lymphoma cells (P＜ 0. 05). After treated with the supernatant of M2 type macrophage culture supernatant, the proliferation ability of lymphoma cells, the number of invaded cells and migrated cells, the levels of MMP-2, MMP-9, PCNA and Ki-67 proteins were significantly increased, compared with the untreated lymphoma cells (P ＜ 0. 05 ). Compared with the lymphoma cells treated with culture medium supernatant of M2 macrophages alone, the lymphoma cells treated with TGF-β1 and M2 macrophage culture medium supernatant showed that the proliferation ability, number of invaded and migrated cells, and the protein levels of MMP-2, MMP-9, PCNA and Ki-67 were significantly increased (P＜0. 05). Conclusions TGF-β1 can reduce the proliferation, invasion and migration of lymphoma cells induced by macrophages. The mechanism of action is related to the expression of MMP-2, MMP-9, PCNA and Ki-67 proteins.

Mortality in all patients with renal failure requiring haemodialysis (n = 4) was 100%. Presence of 3 or more organ failures was associated with 80% mortality (= 0.003).</p><p><b>CONCLUSION</b>Sepsis, multiple organ failure and the need for mechanical ventilation, inotropes and especially haemodialysis were associated with increased risk of mortality in our cohort of HSCT patients.</p>

Second Malignant Neoplasms in Childhood Cancer Survivors Treated in a Tertiary Paediatric Oncology Centre

: One of the most feared complications of childhood cancer treatment is second malignant neoplasms (SMNs). This study evaluates the incidence, risk factors and outcomes of SMNs in a tertiary paediatric oncology centre in Singapore.: A retrospective review was conducted on patients diagnosed with childhood cancer under age 21 and treated at the National University Hospital, Singapore, from January 1990 to 15 April 2012. Case records of patients with SMNs were reviewed.: We identified 1124 cases of childhood cancers with a median follow-up of 3.49 (0 to 24.06) years. The most common primary malignancies were leukaemia (47.1%), central nervous system tumours (11.7%) and lymphoma (9.8%). Fifteen cases developed SMNs, most commonly acute myeloid leukaemia/myelodysplastic syndrome (n = 7). Median interval between the first and second malignancy was 3.41 (0.24 to 18.30) years. Overall 20-year cumulative incidence of SMNs was 5.3% (95% CI, 0.2% to 10.4%). The 15-year cumulative incidence of SMNs following acute lymphoblastic leukaemia was 4.4% (95% CI, 0% to 8.9%), significantly lower than the risk after osteosarcoma of 14.2% (95% CI, 0.7% to 27.7%) within 5 years (<0.0005). Overall 5-year survival for SMNs was lower than that of primary malignancies.: This study identified factors explaining the epidemiology of SMNs described, and found topoisomerase II inhibitor use to be a likely risk factor in our cohort. Modifications have already been made to our existing therapeutic protocols in osteosarcoma treatment. We also recognised the importance of other risk management strategies, including regular long-term surveillance and early intervention for detected SMNs, to improve outcomes of high risk patients.

Longitudinal study of early neural development in premature infants with different gestational age and birth weight / 临床儿科杂志

Objective To investigate the trend of early neural development in premature infants. Methods At the age of 12 months and 24 months, Bayley Scales of Infant Development were used to assess the mental development index (MDI) and the psychomotor development index (PDI) in preterm (corrected age) and full-term infants. Results At 12 months, there was no significant difference in corrected age PDI scores among different gestational age groups (<32 , 32–33+6 and 34–36+6 weeks) (P=0.820). The actual age MDI and PDI scores of full-term infants and premature infants in 34~36+6 weeks group were significantly higher than those of premature infants in <32 and 32-33+6 weeks groups, and the PDI score of full-term infants was significantly higher than that of premature infants in 34-36+6 weeks group (P<0.05). There was no significant difference in actual age PDI scores among different birth weight groups (P=0.166). The actual age MDI and PDI of full-term infants and premature infants in birth weight≥2500 g group were significantly higher than those of premature infants in <1500 g, 1500~1999 g and 2000~2499 g groups (P<0.05). At 24 months, the actual age MDI scores of full-term infants were significantly higher than those of premature infants in different gestational age and birth weight groups (P<0.05). The actual age MDI curve of premature infants in birth weight <1500g group showed a downward trend, while the actual age PDI curve showed a significant upward trend. Conclusion The neurodevelopment of preterm infants at the corrected age of 12 and 24 months reaches the level of full-term infants.
