RESUMO
Objective:To investigate internalized and externalized behavioral problems in children with leukemia and to analyze the influencing factors.Methods:A total of 121 children match the inclusion and exclusion criteria with leukemia hospitalized in Hematology and Oncology Department of 3 hospitals in Zhengzhou city from November 2021 to March 2022 were recruited through a cluster sampling method.The general information questionnaire, Strengths and Difficulties Questionnaire (parent version), Psychological Adaptation Scale, Perceived Social Support Questionnaire and Zarit Burden Interview were used for investigation.Multiple linear regression was used to analyze the influencing factors of internalized and externalized behavioral problems in children with leukemia.Results:Among 121 children with leukemia, there were 72 males and 49 females, with the age of (7.16 ± 3.18) years.The total score of interna-lized and externalized behavioral problems in 121 children with leukemia was (6.12±3.13) points and (5.49±2.92) points, respectively.Multiple linear regression analysis showed that burden of care ( β=0.412, P<0.001), family support ( β=-0.242, P=0.003) and monthly household income per capita ( β=-0.167, P=0.036) were the influencing factors of internalized behavioral problems in children with leukemia.Burden of care ( β=0.360, P<0.001), social integration ( β=-0.223, P=0.008) and caregiver age ( β=-0.176, P=0.035) were the influencing factors of externalized behavioral problems in children with leukemia. Conclusions:Children with leukemia suffer severe internalized and externalized behavioral problems.Burden of care of the caregiver, family support and social integration are predictors of adverse emotional and behavioral problems in children.
RESUMO
Objective:To explore the current situation of emotional and behavioral problems in children with hematological tumors, and the relationship with caregivers′ coping styles and family cohesion.Methods:Using cross-sectional study design and cluster sampling method, caregivers of children with hematological tumors hospitalized in hematology department of five third-class hospitals in Zhengzhou from November 2020 to January 2021 were selected as the respondents. The strengths and difficulties questionnaire (parent version), simple coping style questionnaire, family cohesion scale and self-made general information questionnaire were used for questionnaire survey. Statistical analysis was performed by SPSS 24.0 software using Spearman correlation analysis and multivariate Logistic regression analysis.Results:A total of 237 questionnaires were distributed and 214 valid questionnaires were collected. The abnormal detection rates of total difficulty score, emotional symptoms, conduct problems, hyperactivity, peer interaction problems and prosocial behavior were 17.8%, 22.9%, 10.7%, 8.4%, 39.7% and 13.6% respectively. The results of correlation analysis showed that caregivers′ positive coping was negatively correlated with the total score of difficulties, hyperactivity and peer interaction problems ( r=-0.186, -0.153, -0.174, all P<0.05), and positively correlated with the score of prosocial behavior ( r=0.214, P<0.05). Caregivers′ negative coping was positively correlated with the total score of difficulties, emotional symptoms and hyperactivity ( r=0.203, 0.204, 0.170, all P<0.05). Family cohesion was negatively correlated with the total score of difficulties, emotional symptoms, conduct problems, hyperactivity and peer interaction problems ( r=-0.254, -0.225, -0.183, -0.137, -0.195, all P<0.05), and positively correlated with prosocial behavior ( r=0.235, P<0.01). Multivariate Logistic regression analysis showed that positive coping of caregivers was a protective factor of peer interaction in children ( β=-0.050, OR=0.951, 95% CI=0.907-0.996), while family intimacy was also a protective factor for children with prosocial behavior ( β=-0.045, OR=0.956, 95% CI=0.923-0.991). Conclusion:The emotional and behavior problems of children with hematological tumors are serious, and the positive coping of caregivers and family cohesion have certain predictive value for the occurrence of negative emotional behavior problems in children, so medical staff should take corresponding measures to reduce the occurrence of emotional and behavior problems in children.
RESUMO
Objective To investigate the therapeutic effect of L-carnitine combined with erythropoietin (EPO) and iron on renal anemia in rats. Methods The renal anemia rat model was established using adenine. All rats were randomly divided into three groups: control group (group A), EPO combined with iron group (group B), and L-carnitine combined with EPO and iron treatment group (group C). The levels of red blood cells (RBC), hemoglobin (Hgb), hematocrit (Hct), C-reactive protein (CRP), Fe in peripheral blood (Fe), serum ferritin (SF) and transferrin saturation (TS) were measured. Pathological changes in the kidney, liver and small intestine tissues were examined using HE staining. Results Compared with the group A, the levels of RBC, Hgb, Hct, Fe, SF, and TS were significantly increased, however, the level of CRP significantly decreased in the groups B and C (P＜ 0. 05). In the group C, the levels of RBC, Hgb, and CRP was higher than the group B (P＜ 0. 05). Furthermore, the pathological changes in the kidney, liver and small intestine tissues were improved in the groups B and C. Conclusions L-carnitine combined with EPO and iron has a therapeutic effect on renal anemia in rats, thus, it deserves further studies and application.

In the research, we found that seven mutational sites in preC/C region of HBV were associated with independent risk factors for postoperative survival in patients of HBV-HCC. The following five mutational sites were identified as statistically significant independent predictors of HBV-HCC survival: 1915, 2134, 2176, 2221, 2260. The mutational site of 1979 and 2245 were identified for the association with survival at a borderline significance level.@*Conclusions@#The portal vein thrombosis, tumor TNM classification, size and seven mutational sites in the PreC/C region were identified as independent predictors of postoperative survival in HCC patients.
RESUMO
Objective To explore the effect of forgiveness intervention on improving the happiness index and self-esteem of the elderly.Methods Totally 103 cases who had been offended and did not relieved were enrolled in this research.Two groups were assigned using digital random method.There were 49 cases in the experimental group and 50 cases in the control group that were counted in final statistics according to the inclusion and exclusion criteria.The experimental group received 8-week forgiveness therapy,control group re-ceived no special intervention.Results The scores of well-being,forgiving self,forgiving others and self-es-teem respectively were 3.06±0.97,3.23±0.62,3.01±0.63 and 2.71±0.35 respectively.Forgiving others was positively related with well-being and self-esteem(r=0.296,0.273,P<0.01),and there was no correlation between forgiving self and well-being(r=0.113,P>0.05). Forgiving others(t=5.309,P<0.01),self-esteem (t=2.732,P=0.008),well-being(t=2.732,P=0.008)in experimental group were improved after the inter-vention,but no difference was found in forgiving self(t=1.413,P=0.165). And there were significant differ-ence in both main effect and interaction effect in forgiving others(Fmain=39.05,Pmain<0.01; Finter=34.96, Pinter<0.01),self-esteem(Fmain=26.41,Pmain<0.01; Finter=35.83,Pinter<0.01),well-being(Fmain=20.96,Pmain<0.01;Finter=18.06,Pinter<0.01)at the pre-test,post-test and 1 month after intervention in experimen-tal group. In the control group,there was no significance in main effect(Fmain=1.98,Pmain=0.152),but the interaction effect was significantly different(Finter=10.98,Pinter<0.01).Conclusion Forgiveness interven-tion can improve forgiveness for elderly people.This intervention method has a positive effect on improving the overall happiness index and self-esteem of elderly people who have been subjected to other offenses,unfair treatment or interpersonal conflicts.

RESUMO
Objective To investigate the accumulation of mutations and single nucleotide polymorphisms ( SNPs) in the displacement loop ( D-loop ) of mitochondrial DNA ( mtDNA ) might be associated with cancer risk and disease outcome.Methods We obtained cancerous and noncancerous liver tissues from 49 HBV-related HCC patients at the Fourth Hospital of Hebei Medical University.mtDNA of the liver tissues was extracted with Mitochondrial DNA Extraction Kit.Mutation and polymorphism were confirmed by repeated analysis.We assessed the prediction power of D-loop SNPs in hepatocellular carcinoma ( HCC) patients.Results No mutation in these HCC patients had prediction power for post-operational survival, whereas one SNP site ( nucleotide 150 C/T ) was identified by the log-rank test for statistically significant prediction of HCC survival.In an overall multivariate analysis, allele 150 was identified as an independent predictor of HCC outcome.The length of survival of patients with allele 150C was significantly shorter than that of patients with allele 150T (relative risk, 0.246;95% CI, 0.070–0.861; P=0.028).Conclusions The analysis of genetic polymorphisms in the mitochondrial D-loop helps to identify patient subgroups at high risk of a poor disease outcome.
RESUMO
Objective To study the psychological defence (PD) and coping style (CS) of the patients suffering depressive episode (DE).Methods 104 cases of the experimental group and 104 cases of the control group,which were stratified sampled,had been investigated by applying defensive style questionnaire (DSQ),coping style questionnaire(CSQ).Results The total score of the immature PD of the experimental group(5.19±0.73) was significantly higher (t =2.93,P＜ 0.05) than that of the control group (4.41 ± 0.76).In the immature mechanism,withdrawal,somatization,avoiding,passive aggression were significantly higher,but the complaints and fantasy were significantly lower.The total score of mature PD of the experimental group(4.49±0.61) was significantly lower (t=-6.02,P＜0.01) than that of the control group(6.01±0.85).For the mature mechanism,sublimation and humor were lower and the repression was higher.And for the CS,problem solving,consulting and rationalization scores were significantly lower than those of the control group(t=-4.58,P＜0.01 ; t=-4.49,P＜0.01; t=-4.01,P＜0.01).The self-accusation,retreat scores were significantly higher than those of the control group(t=8.21,P＜0.01; t=5.31,P＜0.01).Conclusion Patients suffering DE are apt to use immature PD and CS.To increase the therapeutic effect,the style of the patients' PD and CS should be highlighted,and it is necessary to take steps to guide the patients to use mature PD and CS.
RESUMO
Mesaconitine was incubated with rat liver microsomes in vitro. The metabolites of mesaconitine in rat liver microsomes were identified by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method with high resolution power. A typical reaction mixture of 100 mol L-1 Tris-HCI buffer (pH 7.4) containing 0.5 gL-1 microsomal protein and 50 micro molL-1 mesaconitine was prepared. The above reaction mixture was divided into six groups, and the volume of each group was 200 micro L. The incubation mixture was pre-incubated at 37 degrees C for 2 min and the reactions were initiated by adding NADPH generating system. After 90 min incubation at 37 degrees C, 200 micro L of acetonitrile was added to each group to stop the reaction. The metabolites of mesaconitine were investigated by UPLC-MS/MS method. Mesaconitine and 6 metabolites M1-M6 were found in the incubation system. The structures were characterized according to the data from MS/MS spectra and literatures. The metabolic reactions of mesaconitine in rat liver microsomes included the demethylation, deacetylation, dehydrogenation and hydroxylation. The major metabolic pathways of mesaconitine in rat liver microsomes were determined by UPLC-MS/MS on multiple reaction monitoring (MRM) mode combined with specific inhibitors of cytochrome P450 (CYP) isoforms, including alpha-naphthoflavone (CYP1A2), quinine (CYP2D), diethyldithiocarbamate (CYP2E1), ketoconazole (CYP3A) and sulfaphenazole (CYP2C), separately. Mesaconitine was mainly metabolized by CYP3A. CYP2C and CYP2D were also more important CYP isoforms for the metabolism reactions of mesaconitine, but CYP1A2 and CYP2E1 haven't any contribution to MA metabolism in rat liver microsomes.
