Acute lymphoblastic leukemia (ALL) is the most common malignant neoplastic disease in children. With the continuous improvement in diagnosis and treatment, there has been an increasing number of ALL children who achieve long-term survival after complete remission; however, a considerable proportion of these children have cognitive impairment, which has a serious adverse impact on their learning, employment, and social life. This article reviews the latest research on cognitive impairment in children with ALL from the aspects of the influencing factors, detection techniques, and prevention/treatment methods for cognitive impairment.

This article reports two cases of children with B-cell acute lymphoblastic leukemia (B-ALL) complicated by invasive fungal disease (IFD) who received bridging treatment using blinatumomab. Case 1 was a 4-month-old female infant who experienced recurrent high fever and limb weakness during chemotherapy. Blood culture was negative, and next-generation sequencing (NGS) of peripheral blood, bronchoalveolar lavage fluid, and cerebrospinal fluid were all negative. Chest CT and cranial MRI revealed obvious infection foci. Case 2 was a 2-year-old male patient who experienced recurrent high fever with multiple inflammatory masses during chemotherapy. Candida tropicalis was detected in peripheral blood and abscess fluid using NGS, while blood culture and imaging examinations showed no obvious abnormalities. After antifungal and blinatumomab therapy, both cases showed significant improvement in symptoms, signs, and imaging, and B-ALL remained in continuous remission. The report indicates that bridging treatment with blinatumomab in children with B-ALL complicated by IFD can rebuild the immune system and control the underlying disease in the presence of immunosuppression and severe fungal infection.

OBJECTIVES: To examine the changes of intestinal flora in children newly diagnosed with acute lymphoblastic leukemia (ALL) and the influence of chemotherapy on intestinal flora. METHODS: Fecal samples were collected from 40 children newly diagnosed with ALL before chemotherapy and at 2 weeks, 1 month, and 2 months after chemotherapy. Ten healthy children served as the control group. 16S rDNA sequencing and analysis were performed to compare the differences in intestinal flora between the ALL and control groups and children with ALL before and after chemotherapy. RESULTS: The ALL group had a significant reduction in the abundance of intestinal flora at 1 and 2 months after chemotherapy, with a significant reduction compared with the control group (P<0.05). Compared with the control group, the ALL group had a significant reduction in the diversity of intestinal flora before and after chemotherapy (P<0.05). At the phylum level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Actinobacteria at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05) and a significant increase in the relative abundance of Proteobacteria at 1 and 2 months after chemotherapy (P<0.05). At the genus level, compared with the control group, the ALL group had a significant reduction in the relative abundance of Bifidobacterium at 2 weeks, 1 month, and 2 months after chemotherapy (P<0.05); the relative abundance of Klebsiella in the ALL group was significantly higher than that in the control group at 1 and 2 months after chemotherapy and showed a significant increase at 1 month after chemotherapy (P<0.05); the relative abundance of Faecalibacterium in the ALL group was significantly lower than that in the control group before and after chemotherapy and showed a significant reduction at 2 weeks and 1 month after chemotherapy (P<0.05). The relative abundance of Enterococcus increased significantly at 1 and 2 months after chemotherapy in the ALL group (P<0.05), and was significantly higher than that in the control group (P<0.05). CONCLUSIONS The diversity of intestinal flora in children with ALL is significantly lower than that in healthy children. Chemotherapy significantly reduces the abundance of intestinal flora and can reduce the abundance of some probiotic bacteria (Bifidobacterium and Faecalibacterium) and increase the abundance of pathogenic bacteria (Klebsiella and Enterococcus) in children with ALL.

OBJECTIVE: To analyze the risk factors affecting prognosis of children with hemophagocytic lymphohistiocytosis (HLH). METHODS: The clinical manifestations and laboratory data of 143 HLH children who met the HLH-2004 diagnostic criteria in Shenzhen Children's Hospital from January 2009 to May 2017 were retrospectively analyzed, and the independent factors affecting prognosis were also analyzed. RESULTS: The median age of 143 HLH children was 1.9 (0.1-14.3) years old, and the median follow-up time was 6.7 years (1 day - 11.9 years). The overall survival rate of 1 month, 1 year, and 10 years was (87.4±5.5)%, (81.1±6.5)%, and (81.1±6.5)%, respectively. The deaths occurred within 1 year after onset. Multivariate analysis showed that central nervous system (CNS) involvement (P=0.047), low hemoglobin (P=0.002), prolonged activated partial thromboplastin time (APTT) (P<0.001), high triglyceride (P=0.005) were all the independent risk factors affecting survival of the children. Receiver operating characteristic curve indicated that APTT (AUC=0.753, P<0.001) was more valuable than other risk factors in predicting death of the children. The cut-off value of APTT was 56.6 s, and the sensitivity and specificity of which was 55.6% and 89.7%, respectively. CONCLUSION Hypohemoglobinemia, prolonged APTT, hypertriglyceridemia, and CNS involvement the risk factors affecting prognosis of HLH, and prolonged APTT shows a strong predictive value for death.

The present situation of the clinical application of dog-days moxibustion (moxibustion applied in the three periods of the hot season) is summarized so as to provide the guide for the theoretic study and clinical application of dog-days moxibustion. The intervention time of dog-days moxibustion is on the 1st day of each of the three periods of the hot season. Simultaneously, the geographic factors are considered. The disorders of lung system are mostly dominant among the indications of dog-days moxibustion, complicated with spleen and stomach disorders as well as cold and deficiency syndromes/patterns. The acupoints are mainly selected from the front- points on the chest and the back- points on the back, in combination with the differentiation of diseases, symptoms/patterns and the disorder stages. The duration of treatment is ranged from 1 to 3 years. The clinical therapeutic effect is improved constantly along with the increase of treatment periods by years.

Objective: To observe the difference in clinical efficacy between acupuncture with point selection based on syndrome differentiation along the meridians and acupuncture at non-meridian and non-acupoint points for functional dyspepsia (FD). Methods: A total of 74 FD patients were randomized into an observation group and a control group, with 37 cases in each group. Both groups received acupuncture treatment. Zusanli (ST 36) and Neiguan (PC 6) were selected in the observation group, with Taichong (LR 3) and Neiting (ST 44) added for excess syndrome, and Gongsun (SP 4) and Yinlingquan (SP 9) added for deficiency syndrome. Four non-meridian and non-acupoint points were selected in the control group. The treatments in both groups were performed once a day with a 2-day break after 5 consecutive treatments, which constituted one treatment course. A total of 4 courses were performed. The scores of Nepean dyspepsia index (NDI) and Leeds dyspepsia questionnaire (LDQ) were recorded before and after treatment, and during follow-up (8, 12, 16, 20 and 24 weeks after recruitment) to assess the clinical efficacy. Results: The NDI scores in the two groups after treatment and at each time point during follow-up were higher than those before treatment (all P<0.05), and the LDQ scores were lower than those before treatment (all P<0.05). The NDI scores after treatment and at each time point during follow-up in the observation group were higher than those in the control group (all P<0.01); the total LDQ score and scores of upper abdominal pain, postprandial satiety and upper abdominal burning sensation after treatment and at each time point during follow-up in the observation group were significantly lower than those in the control group (P<0.01 or P<0.05).. Conclusion: Acupuncture with point selection based on syndrome differentiation along the meridians has a better curative effect than acupuncture at non meridian and non-acupoint points in the treatment of FD.

Objective:To observe the clinical efficacy of treating infantile diarrhea due to spleen deficiency with five-step pediatric tuina of Huxiang school. Methods:Using a randomized controlled trial design, sixty eligible kids with diarrhea due to spleen deficiency were randomized into an observation group and a control group, with 30 cases in each group. The observation group was intervened by the five-step pediatric tuina method of Huxiang school, and the control group received conventional tuina treatment. The intervention was conducted once a day, consecutive 5-day treatment as 1 course, at a 2-day interval between courses, successively for a total of 4 courses. Changes in the primary and secondary symptoms of diarrhea due to spleen deficiency were observed, and the clinical efficacy was evaluated. Results: After treatment, the scores of primary and secondary symptoms and the general score of diarrhea due to spleen deficiency were improved; the improvements in fecal form and frequency, decreased appetite, bloating after meals and fatigue and sluggishness were more significant in the observation group than in the control group. Conclusion: The five-step pediatric tuina method of Huxiang school and conventional tuina both can improve the primary and secondary symptoms in infantile diarrhea due to spleen deficiency, while the former one can produce more significant efficacy.

Background:The increasing prevalence of colorectal cancer (CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment.We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods:We conducted a multicenter,cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014.Each enrolled patient was interviewed using a structured questionnaire.All expenditure data were inflated to the 2014 Chinese Yuan (CNY;1 CNY =0.163 USD).We quantified the overall expenditure and financial burden and by subgroup (hospital type,age at diagnosis,sex,education,occupation,insurance type,household income,clinical stage,pathologic type,and therapeutic regimen).We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results:A total of 2356 patients with a mean age of 57.4 years were included,57.1％ of whom were men;13.9％ of patients had stage Ⅰ cancer;and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY,and the expenditures for stage Ⅰ,Ⅱ,Ⅲll,and Ⅳ disease were 56,099 CNY,59,952 CNY,67,292 CNY,and 82,729 CNY,respectively.Non-medical expenditure accounted for 8.3％ of the overall expenditure.The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY,which accounted for 59.9％ of their previous-year household income and caused 75.0％ of families to suffer an unmanageable financial burden.Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups (P ＜ 0.05),except for sex.Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less (all P ＜ 0.05).Conclusions:For patients in China,direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable.The financial burden varied among subgroups,especially among patients with different clinical stages of disease,which suggests that,in China,CRC screening might be cost-effective.

OBJECTIVETo compare the therapeutic effects of prednisone combined with mycophenolate mofetil (MMF) versus cyclosporin A (CsA) in children with steroid-resistant nephrotic syndrome (SRNS).

METHODSThe clinical data of 164 SRNS children who were treated with prednisone combined with MMF or CsA between January 2004 and December 2013 were collected, and the clinical effect of prednisone combined with MMF (MMF group, 112 children) or CsA (CsA group, 52 children) was analyzed retrospectively.

RESULTSAt 1 month after treatment, the CsA group had a significantly higher remission rate than the MMF group (67.3% vs 42.9%; P<0.05). At 3 months after treatment, the CsA group also had a significantly higher remission rate than the MMF group (78.8% vs 63.3%; P<0.05). The 24-hour urinary protein excretion in both groups changed significantly with time (P<0.05) and differed significantly between the two groups (P<0.05). There were no serious adverse events in the two groups.

CONCLUSIONSPrednisone combined with MMF or CsA is effective and safe for the treatment of SRNS in children, and within 3 months of treatment, CsA has a better effect than MMF.

OBJECTIVETo investigate the changes in brain injury after the induction chemotherapy in children with acute lymphoblastic leukemia (ALL) by cranial MRI.

METHODSThe clinical data and cranial MRI results of 62 children with ALL who were hospitalized from March 2014 to June 2015 were analyzed retrospectively.

RESULTSBefore chemotherapy, MRI showed bone marrow infiltration of the skull in 33 patients (53%); the children with WBC<20×10(9)/Lhad a significantly lower incidence rate of bone marrow infiltration of the skull than those with WBC≥20×10(9)/L (16 patients/42% vs 17 patients/71%; P<0.05), and the high-risk group had a significantly higher incidence rate of bone marrow infiltration of the skull than the non-high-risk group (71% vs 44%; P<0.05). Before chemotherapy, there were 4 cases (7%) of brain atrophy, and 2 cases (3%) of abnormal signals in the sensory conduction bundle. MRI reexamination in 28 patients after 3 months of chemotherapy showed 3 new cases (11%) of brain atrophy and 1 aggravated case of brain atrophy.

CONCLUSIONSThe children with ALL have bone marrow infiltration of the skull, brain atrophy, and abnormal signals in the sensory conduction bundle before chemotherapy, especially bone marrow infiltration of the skull, and some changes in brain injury disappear after treatment.
