Objective To explore the efficiency and prognosis of hematological malignancies treated by haploidentical hematopoietic stem cell transplantation.Methods 70 patients who received haploidentical hematopoietic stem cell transplantation were analyzed retrospectively.According to tumor burden before transplantation,the patients were divided into three groups,the low tumor burden group,the mediate tumor burden group and the high tumor burden group.And then the effection of the tumor burden to survival was analyzed,and the engraftment,GVHD,infection,conditioning related toxicity,relapse and survival rate were also observed.Results The follow-up was terminated on January 1,2014.Follow-ups were performed for a median of 34.05 (7.4-83.6) months after transplantation.All patients achieved engraftments.The cumulative incidence of GVHD of grades 2-4 was 47.14 ％ (33/70) and that of grades 3-4 was 21.4 ％ (15/70).The chronic extensive GVHD was 20.0 ％ (14/70).The overall survival was 68.6 ％.Transplant-related mortality was 12.8 ％ and the relapse was 18.6 ％.The overall survivals in low tumor burden group,mediate tumor burden group,high tumor burden group were 91.67 ％,72.7 ％,33.3 ％ respectively.By SPSS 20.0,tumor burden was the high risk factor affecting the survival (low tumor group vs high tumor group,mediate tumor group vs high tumor group,low tumor group vs high tumor group,P =0.000,P =0.038,P =0.016).Conclusions Haploidentical hematopoietic stem cell transplantation in hematological malignancies is safe and effective.And for hematological malignancies with poor prognosis disease,it should be accepted the HSCT as soon as possible after remission in order to reduce the recurrence rate of malignancy.

Objective To evaluate the efficacy of haploidentical hematopoietic stem cell transplantation (HSCT) with supplemental umbilical cord blood (UCB) infusion in treatment of malignant hematological diseases.Method Clinical data of 66 patients with hematological malignancies treated with HSCT in our hospital between January 2010 and May 2013,were retrospectively analyzed.Among them 25 cases received infusion of human UCB before HSCT (experimental group) and other 41 cases had no UCB injection before HSCT (control group).Results There were no differences in age,gender,donor type,disease categories,disease status before transplant between two groups (P ＞ 0.05).There was a significant difference in conditioning regimes between two groups (P ＜ 0.05),but no clinical implication.The infused mononuclear cell (MNC) count in experimental group was higher than that in control group (9.94 ± 2.88 × 108/kg vs.7.80 ±0.82 × 108/kg,P =0.00),while there were no difference in infused CD34 + cell count (5.46 ±3.54 × 106/kg vs.3.54 ± 1.60 × 106/kg,P =0.16).Neutrophil recovery time in experimental group was shorter than that in control group (13.7 ±2.9 d vs.16.6 ±2.9 d,P =0.023).The incidences of grade Ⅲ-Ⅳ acute graft versus host disease (aGVHD,P =0.036),bacterial infection (P =0.001) and fungal infection (P =0.001)and hemorrhagic cystitis (P =0.00)in experimental group were lower than those in control group.There were no significant differences in platelet recovery time(P =0.43),the incidence of grade Ⅰ-Ⅱ aGVHD (P =0.27),implanted syndrome (P =0.24),sinusoidal obstruction syndrome (P =0.57)and viraemia (P =0.31)between two groups.Conclusion HSCT with supplemental infusion of human UCB may alleviate the degree of aGVHD,but the long-term outcome remains to be studied.

Dietary intervention is essential as a primary prevention measure for cardiovascular diseases. Nurses master scientific dietary guidance methods, which can help reduce the risk of cardiovascular diseases in high-risk groups and reduce the medical burden of cardiovascular diseases. This paper reviews the classification of intermittent fasting, its impact on cardiovascular risk factors, its possible mechanisms for preventing cardiovascular diseases, its safety and compliance, and suggestions on domestic cardiovascular research. In order to provide references for future research in China.

Dementia is common in the aging group, person-centered care(PCC) has been widely regarded as the best caring approach for dementia residents by researchers. PCC includes two main approaches: dementia care mapping(DCM) and some treatment routes for exploring agitation(TREA). It has been verified that caregivers’ job satisfaction and competence can also be improved through such caring approach. However, theories about PCC has not been spread in China commonly, and there is still a few studies on it.

Objective: To investigate the safety and efficacy of haploidentical hematopoietic stem cell transplantation with different intensity conditioning regimen in the treatment of childhood aplastic anemia (AA) . Methods: Thirty-seven AA patients who underwent haploidentical transplantation in BaYi Children's Hospital Affiliated to PLA Army General Hospital from January 2013 to January 2017 were enrolled. According to the dosage of conditioning regimen, 34 patients excluding 3 other conditioning regimens were divided into high-dosage group (regimen 2, 22 cases) and low-dosage group (regimen 3, 12 cases). The data of Engraftment, graft-vs-host disease (GVHD), hematopoietic reconstitution, relapse, infection, overall survival (OS) were analyzed. The comparison between the two groups was tested by χ² test. Results: A total of 35 of 37 patients achieved primary engraftment; 2 cases died of regimen-related toxicity and severe infection before the infusing of the grafts. The activation rate of CMV and EBV was 60% (21/35) . Post-transplant lymphocyte disease (PTLD) of lung occurred in one case. The cumulative incidences of acute GVHD grade Ⅰ-Ⅳ and chronic GVHD were 29% (10/35) and 34% (12/35) respectively and the incidence of extensive chronic GVHD was 6% (2/35) . The median follow-up time was 18.8 (2.9-44.1) months, the OS was 92% (34/37) .All survived patients were no longer dependent on blood transfusion and none of them had recurrence. Comparing the rates of overall survival(86%(19/22) vs.100%(12/12)) and rates of chronic GVHD(40%(8/20) vs. 17%(2/12)) in regimen 2 and regimen 3 group, there were no significant difference (χ²=1.742, 1.841, all P>0.05) . Significant difference was found at the incidence of Ⅰ-Ⅳ acute GVHD (10% (2/20) vs. 50% (6/12) ,χ²=6.200, P=0.013). Conclusions Haploidentical hematopoietic stem cell transplantation is effective and safe. It is suitable for patients who are not eligible for matched donor transplantation. Application of reduced dose preconditioning in haploid transplantation is worth exploring.
