Objective:To cultivate human-derived prostate cancer (PCa) cells via conditional reprogramming cell (CRC) technology, and establish individualized cell bank for PCa research in vitro.Methods:We obtained three fresh PCa tissue samples from different patients between January 2019 and April 2019. Then each sample was divided into two parts. One was used for cancer nature confirmation by intraoperative biopsy. Another part was sent to the laboratory and digested into single primary cancer cells with 0.25% EDTA enzyme for CRC technology. The details were described as followed: 1. The primary PCa cells were co-cultured with 3T3-J2 cells irradiated by 30 Gy (feeder cells) in conditioned medium, and observed for the growth of cell clones, 2. The feeder cells were removed by 0.25% EDTA trypsin for 1 minute before primary PCa cells digested for passage. All primary PCa cells were validated by multiple experiments such as immunofluorescence, immunohistochemistry, immunoblotting and fluorescence in situ hybridization (FISH).Results:Total three cases of human-derived PCa cell lines were successfully established during 15days through CRC technology. All those primary PCa cells could be steadily and continuously passaged, which also expressed AR, CK5, CK18, P504s and PSA. FISH demonstrated that each cell line harbored≥1.6% TMPRSS2/ERG fusion and conformed to the features of PCa.Conclusion:CRC technology can be used for stable and continuous PCa cell culture in vitro.

Objective:To explore the knowledge of pediatric nurses about intravenous infusion therapy, find the problems, and provide a reference for managers to provide targeted training.Methods:In this multicenter cross-sectional study, the nurses on duty were selected from 43 hospitals under the medical alliance of Beijing Children's Hospital by convenient sampling from July 24th to 31st, 2018. The self-made questionnaires were used in this study, and data were collected online through wjx.cn. The questionnaires were developed by 4 veteran venous infusion therapists according to the Infusion Therapy Standards of Practice (2016 ) as well as the Technical Standards for Intravenous Therapy Nursing Issued by the National Health Commission of the People's Republic of China in 2014. The questionnaire mainly included three parts. Part I was the basic information of the respondent subjects and hospitals; Part II was the knowledge of the subjects about domestic standards for infusion therapy and Infusion Therapy Standards of Practice; and Part III the knowledge of the subjects about infusion therapy operations and maintenance as well as the current status of infusion therapy in their departments. SPSS 17.0 was used for statistical analysis. Results:A total of 8 405 pediatric nurses were investigated in this study. The average knowledge of infusion therapy was (11.72±2.41), and the pass rate was 54.8%. The survey showed that nurses performed well in selecting infusion tools and puncture sites according to the nature of the drug, evaluating the patient and treatment plan before infusion therapy, the sealing method of peripheral vein indwelling needles, and treatment methods when resistance was encountered or no blood was returned in suction. The univariate analysis revealed that the level of the hospital, whether the hospital had a dosing center and an infusion therapy group, the nurse's education, job title, working years, position, and whether to teach young nurses were the main influencing factors to nurses' knowledge about infusion therapy ( P<0.05) . The results of Logistic regression analysis showed that whether the hospital had a dosing center and a infusion therapy group, and the nurse's education background, title, working years, position, and teaching were the main influencing factors for the nurse's knowledge of infusion therapy ( P<0.05) . Conclusions:Pediatric nurses have insufficient knowledge about infusion therapy. They need to be further trained in the basics of infusion therapy, especially in the correct use of infusion tools, the proper selection of puncture sites, and catheter maintenance.

Objective:To construct the content and form of peer support for cervical cancer chemotherapy patients so as to form an operable peer support program for cervical cancer chemotherapy patients in line with my country's clinical reality.Methods:From November 2018 to November 2019, we initially formulated the peer support program for cervical cancer chemotherapy patients through literature review, qualitative research and questionnaire survey. The Delphi method was used to conduct two rounds of letter inquiries with 18 domestic experts who were familiar with cervical cancer peer support related fields to provide objective opinions and suggestions from different levels and angles.Results:The effective recovery rate of the two rounds of questionnaires was 100.00%, the expert authority coefficient was 0.858 and the Kendall harmony coefficients were 0.240 and 0.267. The final peer support program for cervical cancer chemotherapy patients included 4 first-level indicators (forms of peer support, emotional support, information support and social adaptation support) and 29 second-level indicators.Conclusions:The peer support program based on the Delphi method is scientific and feasible which provides a scientific basis for the peer support of cervical cancer chemotherapy patients.

Objective: To analyze the efficacy of HLA-haploidentical peripheral hematopoietic stem cell transplantation (haplo-PBSCT) following reduced intensity conditioning (RIC) regimen to treat the patients with hematological malignancies who were older than 50 years old. Methods: Eighteen patients with hematological malignancies over 50 years were enrolled, including 8 male and 10 female patients. The median age of all patients was 52 (range: 50–66) years. Of them, 8 patients had acute myeloid leukemia (AML) , 2 chronic myelocytic leukemia (CML) , 5 myelodysplastic syndrome (MDS) , 2 acute lymphoblastic leukemia (ALL) , and 1 aggressive natural killer cell leukemia (ANKL) . All patients received fludarabine, cytarabine and melphalan with rabbit anti-human thymocyte globulin (FAB+rATG regimen) and transplanted with high dose non-T cell-depleted peripheral hematopoietic stem cells from donors. Enhanced graft versus host disease (GVHD) prophylaxis and infection prevention were administered. Results: Fifteen days after transplantation, 16 patients achieved complete donor chimerism. One of them rejected the donor graft completely at thirty days after transplantation, and the other 2 patients had mixed chimerism 15 days after transplantation and converted to complete recipient chimerism at 30 days after transplantation. The cumulative incidence of acute GVHD (aGVHD) was 61.1% (95%CI49.6%-72.6%) . The incidence of grade Ⅱ-Ⅳ aGVHD was 35.4% (95%CI 21.1%-49.7%) , whereas grade III-IV was 13.8% (95%CI 4.7%-22.9%) . The 2-year cumulative incidence of chronic GVHD (cGVHD) rate was estimated at 38.2% (95%CI 25.5%-50.9%) . Patients were followed-up for a median of 14.5 months (range, 3-44 months) . The Kaplan Meier estimates of 2-year overall survival (OS) and disease-free survival (DFS) was 72.6% (95%CI 60.1%-85.1%) and 63.7% (95%CI 49.2%-78.2%) , respectively. The 2-year cumulative incidence of relapse and non-relapse-mortality (NRM) was 31.2% (95%CI 16.5%-45.9%) and 12.5% (95%CI 4.2%-20.8%) , respectively. Conclusion RIC-haplo-PBSCT protocol can achieve better results in patients with hematologic malignancies over 50 years old.

OBJECTIVETo study the clinical features of acute graft-versus-host disease (aGVHD) and its risk factors for the related HLA-haploidentical non T cell-depleted in vitro peripheral hematopoietic stem cell transplantation (RHNT-PBSCT).

METHODSFrom July 2002 to December 2012, 104 patients who underwent the RHNT-PBSCT were enrolled to analyze the incidences, location and its risk factors of aGVHD, compared with those of the 103 patients who received the HLA-matched sibling non T cell-depleted in vitro PBSCT (MSNT-PBSCT) in the same period.

RESULTS(1)The cumulative incidence of aGVHD in the RHNT-PBSCT group was significantly higher than the MSNT-PBSCT group [(56.2±4.7)% vs (34±3.6)%, P<0.05], but the cumulative incidences of II-IV and III-IVgrade aGVHD had no significant difference between the two groups[(39.5±2.9)% vs (21.2±5.4)%, P>0.05; (12.6±4.1)% vs (10.8±2.4)%, P>0.05]. (2)The cumulative incidence of cutaneous aGVHD was significantly higher in RHNT-PBSCT group than that in MSNT-PBSCT group [(42.3±3.2)% vs (17.5±2.3)%, P<0.05]. The cumulative incidences of liver and gastrointestinal aGVHD between the two groups had no significant difference [(7.7±2.1)% vs (12.6±3.4)%, P>0.05; (16.3±4.5)% vs (10.3±2.5)%, P>0.05]. (3)The 3-year disease free survival (DFS) and overall survival(OS) of RHNT-PBSCT group and MSNT-PBSCT group were (63±5.5)%, (65.2±4.7)% and (74.2±5.4)%, (77.4±5)% respectively, without significance (P=0.078, P=0.052). (4)aGVHD occurrence with HLA haplotype (P=0.003) and matched loci (P=0.002) were significantly correlated by univariate analysis. Multivariate analysis showed that only the HLA typing is a risk factor for aGVHD (HR=1.891, P=0.03).

CONCLUSIONAlthough the incidence of total aGVHD in RHNT-PBSCT protocol is higher than that in MSNT-PBSCT, but there was no significance in severe aGVHD and cutaneous aGVHD was the common type, which indicates that RHNT-PBSCT protocol is feasible.
