Objective To investigate the nurses′ styles of handling interpersonal conflict and jobachievements,and analyze the relationships between them.Methods A total of 610 nurses in four hospitals were recruited by convenience sampling method and investigated with general state scale,the Rahim Organitional Conflict Inventory- Ⅱ and the Job Performance Appraisal Scale for nurses in four hospitals,the results underwent analysis.Results The factor scores of the Rahim Organitional Conflict Inventory- Ⅱwere sent in the descending order as integrating,avoiding,obliging and dominating.The factor scores of jobachievements were sent in the descending order as task,situation,anti-product.Integrating was positively correlated with task and situation,negatively correlated with anti-product,obliging was negatively correlated with task,positively correlated with anti-product.Conclusions Integrating styles of handling interpersonal conflict benefits to accomplish nurses′ job achievement.

Cytosine deaminase (CD) gene is a kind of suicide gene, cytosine deaminase can catalyze the conversion from 5 - fluorocytosine (5 - FC) into 5 - fluorouracil (5 - FU), this combination therapy (CDgene/5 - FC) were widely used in cancer therapy. The results of many researches in different cancer cells have demonstrated that it can inhibit tumor growth significantly. The mechanism includes 5 - FU's direct killing tumor cells and its bystander effect. It can also be used as a potential purging method for autologous hematopoietic cells transplantion after chemotherapy in breast cancer patients. CD/5 - FC combined with other therapies would be an important future research approach.

Objective To investigate the current situation of clinical nurses′ rights & interests maintenance and occupational stress in Hengyang, and explore the relationship between nurses′rights&interests maintenance and occupational stress.Methods Totally 690 nurses from ten secondary and tertiary hospitals in Hengyang were surveyed during August and September 2015 by general information questionnaires, nurses′rights & interests maintenance questionnaire and nurses occupational stress scale.Results The scores of nurses′rights & interests maintenance and nurses′occupational stress were (3.47±0.67), (3.21±0.95). The score and dimension scores of nurses′rights&interests maintenance were negative correlated with the total score and factor scores of nurses′occupational stress (r=-0.263- -0.425,P< 0.01). Job stress, one child or not, age, role adaptation, monthly income were indicated as predictive factors of rights & interests maintenance of nurses. Conclusions Rights & interests maintenance and occupational stress of nurses has a significant correlation, therefore, the medical and health institutions should further implement relevant laws and regulations; protect rights and interests of nurses from different aspects to reduce occupational stress;and stabilize the nursing team and promote development of nursing career.

Objective To evaluate the safety and efficacy of haploidentical hematopoietic stem cell transplan-tation(haplo-HSCT)treatment in children with hematological diseases.Methods Fifty-nine cases of less than 14 years old children with hematonosis were analyzed retrospectively,who were enrolled in the Aerospace Central Hospital from July 2012 to June 2016.And the evaluation was carried out by analyzing the success rate of implantation,occu-rrence rate of graft versus host disease(GVHD),infection rate and transplant related mortality(TRM),cumulative re-currence rate,overall survival rate(OS)and disease-free survival rate(DFS).Results In total of 59 cases,the 59 engraftments were successfully transplanted,the median time of leukocyte engraftment was 18(8-23)days,the median time of platelet engraftment was 21(11-68)days,the bone marrow was assessed 28 days after transplanta-tion,which showed that 59 patients achieved complete remission(CR)and DNA test confirmed complete donor chime-rism.With a median of follow-up time of 19(5-56)months,the cumulative recurrence rates ofⅠ,Ⅱgrade andⅢ,Ⅳ grade acute GVHD were(38.3 ± 6.3)%(23 cases)and(16.7 ± 4.8)%(10 cases),respectively,the chronic GVHD cumulative recurrence rate was(65.6 ± 7.5)%(30 cases),the cytomegalovirus(CMV)viremia cumulative recurrence rate was(45.1 ± 6.5)%(27 cases),the Epstein-Barr virus(EBV)viremia cumulative recurrence rate was(10.0 ± 3.9)%(6 cases),the viral cystitis cumulative recurrence rate was(20.0 ± 5.5)%(12 cases),the transplant related mortality was(12.8 ± 6.0)%,the 2-year cumulative recurrence rate of CR group was(8.0 ± 5.4)%,and that of non-remission(NR)group was(64.1 ± 11.9)%.The 2-year OS of CR group was(78.9 ± 7.5)%,the 2-year OS of NR group was(32.5 ± 12.9)%,the 2-year DFS of CR group was(79.5 ± 9.8)%,the 2 years DFS of NR group was(27.4 ± 7.9)%.Conclusions Haplo-HSCT is safe and effective in treating children with hematonosis,and haplo-HSCT has high survival rate and low recurrent,especially when transplantation is per-formed in the remission stage.But the prognosis of haplo-HSCT is poor in the refractory and relapsed patients,and to explore the preventing recurrence measures are very urgent.

Objective To explore the safety and efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in refractory or relapsed leukemia patients undergoing total body irradiation and FLAG regimen consisting of fludarabine,cytarabine,granulocyte colony stimulating factor (TBI/FLAG).Methods Forty-seven cases of refractory or relapsed leukemia treated in our hospital between May 2012 and December 2015 were analyzed retrospectively,including 14 cases of acute lymphoblastic leukemia,31 cases of acute myeloid leukemia,2 cases of acute transformation of chronic myelocytic leukemia.All patients did not achieve remission before bone marrow transplantation.The proportion of blast cells was 10％-98％.The TBI/FLAG was the main conditioning regimen.Kaplan-meier curve was used to analyze the cumulative incidence of GVHD,cumulative recurrence rate,overall survival rate (OS) and disease-free survival rate (DFS).Results Of 47 cases,there was only one patient with infection during the preconditioning and the cell engraftment was not successful,and the rest 46 patients were successfully engrafted.The median time of leukocyte engraftment was 17 (11-25) days,and the median time of platelet engraftment was 21 (11-70) days.The cumulative incidence of acute GVHD was (62.3 ± 7.3)％,including 51.1％ and 28.4％ in Ⅱ and Ⅲ-Ⅳ grade respectively.Twenty-four patients suffered chronic GVHD in 44 assessable patients,and the cumulative incidence was (77.1 ± 11.2)％.The bone marrow was assessed 28 days after transplantation,and the results showed that 46 patients achieved complete remission,and DNA test confirmed complete donor chimerism.The median follow-up time was 12 (1-44) months,25 patients survived (53.19％,25/47),and 13 relapsed (27.65％,13/47).The 1-yearOS and DFS was 47.9％ and 45.5％ after transplantation.Conclusion TBI/FLAG-based regimen is safe and effective for refractory or relapsed leukemia,and the major risk still is relapse for refractory or relapsed leukemia patients after transplantation.The method of preventing recurrence needs to be further explored.

Objective To evaluate the diagnostic value of quantitative detection of cytomegalovirus (CMV) DNA from different sources [plasma, sputum and bronchoalveolar lavage fluid(BALF)] for CMV pneumonia after allogeneic hematopoietic stem cell transplantation. Methods Clinical data of 405 recipients undergoing allogeneic hematopoietic stem cell transplantation were retrospectively analyzed. Among them, 19 recipients diagnosed with CMV pneumonia were assigned into the CMV pneumonia group, and 229 recipients with CMV viremia alone, 11 recipients without CMV pneumonia who received fiberoptic bronchoscopy and 16 recipients diagnosed with bacterial or fungal pneumonia based on pathogenic evidence receiving sputum culture were assigned into the control A, B and C groups, respectively. The incidence of CMV pneumonia was summarized. The CMV DNA load of specimens from different sources (plasma, sputum and BALF) of recipients with CMV pneumonia was analyzed. The clinical prognosis of recipients with CMV pneumonia was evaluated. Results Among 405 recipients undergoing allogeneic hematopoietic stem cell transplantation, 19 cases developed CMV pneumonia, and the overall incidence of CMV pneumonia was 4.7%(19/405). The CMV DNA load in the plasma, sputum and BALF of recipients with CMV pneumonia was higher than those in the control A, B and C groups (all P < 0.05). In the 19 recipients, 12 cases were cured after antiviral treatment and 7 died from treatment failure(3 cases abandoned treatment). The fatality was 37%(7/19). Conclusions Quantitative detection of CMV DNA in the plasma, sputum and BALF may increase the diagnostic rate of CMV pneumonia, thereby improving clinical prognosis of recipients undergoing allogeneic hematopoietic stem cell transplantation.

Objective To investigate the clinical efficacy of pretreatment regimen containing idarubicin (IDA) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) for high-risk refractory leukemia. Methods A total of 116 patients with high-risk refractory leukemia who received allo-HSCT treated with 7 types of IDA-containing pretreatment regimes were enrolled in this study. The implantation rate of 116 recipients was summed up. The 2-year overall survival (OS), 2-year disease free survival (DFS), cumulative recurrence rate, recurrent mortality, transplantation related mortality (TRM), cumulative incidence of acute graft-versus-host disease (aGVHD) and chronic graft-versus-host disease (cGVHD) were statistically analyzed by Kaplan-Meier survival curve. Results All 116 recipients successfully implanted. The median follow-up time was 28 (7-70) months. Among them, 64 recipients survived, the 2-year OS was 55.2%, 2-year DFS was 51.7%, 2-year recurrent mortality was 23.3% and 2-year TRM was 18.1%. Among 116 recipients, 72 cases suffered from aGVHD. The 2-year cumulative incidence rate of aGVHD was 62.1% including 20 cases of grade Ⅲ-Ⅳ aGVHD, the 2-year cumulative incidence rate was 17.2%. Among 116 recipients, 59 cases presented with cGVHD. The 2-year cumulative incidence rate was 55.4%, of which the 2-year cumulative incidence rate of extensive cGVHD was 14.7%. Among 116 recipients, 30 cases recurred with a 2-year cumulative recurrence rate of 25.9%. Conclusions IDA-containingpretreatment regime has high safety and effectiveness, and can be used as an effective pretreatment regime for transplantation preprocessing in patients with high-risk refractory leukemia.
