Objective:To explore the characteristics, diagnosis, and treatment of precursor B-cell acute lymphocytic leukemia with C- MYC rearrangement (preBLL) in children. Methods:The clinical data in 2 cases of childhood preBLL in Department of Hematology, Children′s Hospital Affiliated to Capital Institute of Pediatrics in June and August 2019 were summarized and analyzed.Results:Both cases were acute lymphoblastic leukemia with precursor B-cell immunophenotype.Hepatosplenomegaly and peripheral white blood cells were significantly increased, and the morphology of bone marrow was L3. C- MYC rearrangement was discovered by cytogenetic tests.Both children have received the treatment of the mature B-cell tumor protocol (FAB/LMB96), and early remission was developed in 1 case with TP53 gene mutation but relapsed thereafter and died finally.Another case had reached sustained complete remission after treatment. Conclusions:Children with preBLL is rare, and routine C- MYC rearrangement should be performed in children with Precursor B-cell lymphoblastic leukemia whose morphology of bone marrow was L3.Its treatment needs to be further studied, and multi-center clinical trials need to be actively conducted to analyze and summarize large numbers of cases to identify effective protocol and improve the prognosis.

Objective To investigate the correlation between serum level of visfatin and type 2 diabetes mellitus (T2DM). Methods Impaired glucose regulation (IGR) group consisted of 40 patients,T2DM group consisted of 106 patients, while control group consisted of 86 subjects. The serum visfatin levels of all groups were detected by enzyme linked immunosorbent assay (ELISA). Results Fasting serum visfatin levels in IGR group and T2DM group were significantly higher than those in control group [(19.93 ±6.89) μg/L and (29.53 ± 11.33) μg/L vs. (16.12 ± 5.24) μ g/L, P ＜ 0.01]. Fasting serum visfatin levels positively correlated with waist-to-hipratio (WHR) (r = 0.161, P ＜ 0.05); significantly positively correlated with triacylglycerol (TG), low density lipoprotein cholesterol (LDL-C), glycosylated hemoglobin (HbA1c),fasting plasma glucose (FPG), fasting insulin (FINS), lg Homeostasis model assessment-insulin resistance index (HOMA-IR) (r = 0.189,0.266,0.643,0.574,0.285,0.526,P ＜ 0.01), and significantly negatively correlated with high density lipoprotein cholesterol (HDL-C)(r =-0.377,P ＜0.01). When visfatin was analyzed as a dependent variable in multiple linear regression, HbA1c (β = 0.512, P = 0.000), lg HOMA-IR (β= 0.172, P = 0.026), WHR (β = 0.119, P = 0.036) were into the equation. Conclusion Visfatin may be involved in glucose and lipid metabolism regulation, and closely related with insulin resistance; visfatin may be a risk factor for T2DM.

Objective Base on the neighborhood activation model(NAM), to develop the Mandarin monosyllable lexical neighborhood test(M-LNT-monosyllable), which is expected to be useful for evaluating speech perception performance in children with hearing loss. Methods Test items were based on the lexical characteristics of word frequency and neighborhood density which addressed in the neighborhood activation model (NAM). M-LNT -monosyllable consisted of two parts: Lexically "easy" words with high word frequency, which were low phonemically similar to the target word and lexically "hard" words with low word frequency, which were high phonemically similar to the target word. 34 children of 3～5 year old with normal hearing were choosed as subjects to verify easy word and hard word lists. Results 1 979 words for children contained 487 easy words and 419 hard words. Three easy word lists and three hard word lists were developed to estimate the performance of word recognition among normal- hearing children. There were no differences among scores of three easy words lists(P＞0.05), and no difference among scores of three hard words lists(P＞0.05). But there were significant differences between scores of easy and hard words lists(P＜0.01). Conclusion The development of the lexicon was affected by the lexical characteristics. Normal-hearing children with some lexical techniques were affected by the lexical characteristics when they recognized the spoken words, but children with less lexical technique didn't show the same result because the recognition was processed on the phonetic level.

Objective: To explore the clinical efficacy of thymalfasin on the immune function and inflammatory response in the treatment of patients with severe pneumonia. Methods: From June 2015 to June 2018, 86 patients with severe pneumonia in the Hospital of Zhejiang Provincial General Team of Armed Police were enrolled in the study.According to different treatment methods, they were divided into control group and treatment group, with 43 cases in each group.The control group was treated with cefoperazone/sulbactam sodium on the basis of conventional treatment.The treatment group was treated with thymalfasin on the basis of the treatment of the control group.The expression of monocyte human leukocyte antigen-DR (mHLA-DR), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels were measured before and after treatment.At the same time, CD₄⁺, CD₈⁺, CD₄⁺/CD₈⁺ before and after treatment were examined in the two groups.The efficacy and bacterial clearance rate of the two groups were evaluated.The adverse reactions were recorded. Results: After treatment, the levels of IL-6 and TNF-α in the two groups were significantly lower than those before treatment [treatment group: (44.9±11.8)ng/L, (42.9±13.1)ng/L vs. (86.5±27.9)ng/L, (79.6±28.6)ng/L, control group: (71.5±14.2)ng/L, (65.9±22.6)ng/L vs. (87.1±28.6)ng/L, (78.8±29.1)ng/L, t=9.005, 7.650, 3.203, 2.295, all P<0.05]. The expression level of mHLA-DR in the treatment group after treatment [(44.8±5.7)%] was significantly higher than that before treatment [(27.1±3.4)%, t=17.487, P=0.000]. The changes of the indicators in the treatment group were significantly better than those in the control group (t=9.447, 5.773, 8.725, all P<0.05). After treatment, the CD₄⁺ level of the two groups were higher than those before treatment, and the CD₈⁺ levels of the two groups were significantly lower than those before treatment, the differences were statistically significant(t=3.050, 3.429, 6.965, 13.327, all P<0.05), and the CD₄⁺/CD₈⁺ of the two groups were significantly increased (t=0.370, 3.314, all P<0.05). The indicators of the treatment group were improved more significantly than the control group (t=4.416, 12.355, 3.089, all P<0.05). The bacterial clearance rate of the treatment group was 88.89% (32/36), which was significantly higher than that of the control group [67.65% (23/34), χ²=4.686, P=0.030]. The clinical efficacy of the treatment group was 93.02%(40/43), which was significantly higher than 76.74%(33/43) of the control group (χ²=6.095, P=0.047). The incidence of adverse reactions between the two groups had no statistically significant difference (χ²=0.212, P=0.645). Conclusion Thymalfasin in the treatment of patients with severe pneumonia can improve the immune function, reduce the inflammatory response, improve the bacterial clearance rate and clinical efficacy, and will not increase the adverse reactions, so it is worthy of promoting.

Objective:To investigate the clinical application value of craniotomy with hematoma evacuation combined with decompressive craniectomy in the treatment of severe traumatic brain injury.Methods:Sixty-eight patients with severe traumatic brain injury who received treatment in China Coast Guard Bureau Hospital, China between June 2016 and June 2019 were randomly assigned to receive either craniotomy with hematoma evacuation combined with decompressive craniectomy (observation group, n = 34) or conventional craniotomy (control group, n = 34). Surgical value for severe traumatic brain injury and the occurrence of complications were compared between the observation and control groups. Results:Before treatment, there were no significant differences in intracranial pressure, National Institute of Health Stroke Scale score, activity of daily living between the observation and control groups (all P > 0.05). After 7 days of treatment, intracranial pressure in the two groups was significantly decreased compared with before treatment, and intracranial pressure in the observation group was significantly lower than that in the control group ( t = 17.284, P < 0.001). After treatment, Glasgow Coma Scores were significantly increased in the two groups, and Glasgow Coma Scores in the observation group were significantly higher than those in the control group ( t = 5.823, 7.185, 9.234, all P < 0.05). In addition, the numbers of patients with grade I, II and III severe traumatic brain injury in the observation group were significantly lower than those in the control group (all P < 0.05). The number of patients with grade V prognosis in the observation group was significantly higher than that in the control group [20 (58.8%) vs. 8 (23.5%), χ2 = 8.743, P < 0.05]. After treatment, severe traumatic brain injury was mitigated in the two groups. National Institute of Health Stroke Scale score in the observation group was significantly lower than that in the control group, and the activity of daily living in the observation group was significantly higher than that in the control group. The numbers of patients with delayed hematoma, a need for reoperation, hydrocephalus, acute encephalocele, epilepsy, and intracranial infection in the observation group were significantly lower than those in the control group. Conclusion:Craniotomy with hematoma evacuation combined with decompressive craniectomy for treatment of severe traumatic brain injury can greatly decrease intracranial pressure, reduce the degree of injury and improve prognosis.

Objective To explore the classification and changes of macrophage subsets in liver transplant rejection.Methods Rat liver transplantation model were established and divided into immune tolerance group(B-B),where the liver of BN rat donors was transplanted to BN rat recipients,and immune rejection group(L-B),in which the liver of Lewis rat donors was transplanted to BN rat recipients.Single-cell RNA sequencing and high-throughput RNA sequencing were used to distinguish the macrophage subsets of rat liver transplantation,and to find differential gene in rejection reactions.Immunohistochemistry was used to determine the changes and distribu-tion of protein expression and cell subsets.Results CD68 positive macrophages were higher in the rejection group than that in the tolerance group(P<0.05),and macrophages could be divided into 9 subsets.During the rejection reaction,the CXC chemokine ligand 9(CXCL9)in the 8th subsets of macrophages was significantly increased,while the gene for white blood cell differentiation antigen 74(CD74)in the 5th subsets was significantly increased(P<0.05).CD74 ranked first in the differential gene synthesis of macrophages during rejection,followed by CXCL9.Compared with the tolerance group,a large number of CD74 positive macrophages were observed in the hepatic portal area of the rejection group,and the infiltration of CD74 positive macrophages in the hepatic sinuses was also significantly increased(P<0.05),while a large number of CXCL9 positive macrophages were observed in the hepatic portal area and hepatic sinuses of the rejection group,especially in the portal area(P<0.05),and CD14 positive cells were significantly increased(P<0.05).Conclusions The CD74 positive macrophage subsets and CXCL9 positive macrophage subsets may be key subgroups in promoting liver transplant rejection,improving the mechanism of macrophage action in liver transplant rejection.
