Objective:To explore the mediating effect of achievement motivation between perfectionism and procrastination behavior of hematology nurses.Methods:Using the stratified sampling method, a total of 280 hematology nurses from 14 Class Ⅲ Grade A hospitals in Henan Province were selected as the research objects from April 2022 to April 2023. A survey was conducted on hematology nurses using general information questionnaire, the Achievement Motive Scale (AMS), the Chinese Frost Multidimensional Perfectionism Scale (CFMPS) and General Procrastination Scale (GPS). Pearson correlation analysis was used to test the correlation between achievement motivation, perfectionism and procrastination behavior. AMOS 26.0 software was used to establish a structural equation model and verify the mediating effect.Results:A total of 280 questionnaires were distributed in this study, and 271 valid questionnaires were collected, with an effective response rate of 96.79%. Among 271 hematology nurses with AMS, the score for pursuing success was (51.95±10.38), and the score for avoiding failure was (53.11±8.91). The total score of CFMPS was (83.79±17.18) and the total GPS score was (61.71±9.50). Perfectionism was negatively correlated with procrastination behavior ( P<0.01), perfectionism was positively correlated with the pursuit of success ( P<0.01), perfectionism was negatively correlated with avoidance failure ( P<0.01), procrastination behavior was negatively correlated with the pursuit of success ( P<0.01) and procrastination behavior was positively correlated with avoidance failure ( P<0.01). Achievement motivation played a partial mediating role between perfectionism and procrastination behavior, with the mediating effect accounting for 47.89% of the total effect. Conclusions:The procrastination behavior and perfectionism of hematology nurses are both in the medium level. Both the pursuit of success and avoidance of failure have partial mediating effects between perfectionism and procrastination. From the perspective of behavioral motivation, strengthening the education and guidance of hematology nurses can avoid procrastination behavior, which has certain guiding significance for the career planning of hematology nurses.

Objective To explore the dynamic changes in monoamine oxidase A(MAOA)and forkhead box A1(FOXA1)levels during neuroendocrine differentiation(NED)in prostate cancer,providing new strategies for the treatment of neuroendocrine prostate cancer.Methods Cell models and mouse transplantation models of NED were established through long-term sustained induction with enzalutamide(ENZ).Dynamic expression of MAOA and FOXA1 in NED was detected by Western Blot and Real-time PCR.GEO database data were selected to analyze the dynamic trends in MAOA and FOXA1 levels in multiple NED models.We constructed a mouse transplantation model of human prostate cancer cell lines and analyzed the dynamic expression of MAOA and FOXA1 in the in vivo NED model by immunohistochemistry.MAOA expression was disrupted with lentiviral transfection,and the impact on FOXA1 was detected.Results Both MAOA and FOXA1 concentrations showed dynamic characteristics,increasing and then decreasing during the NED process.Knockdown of MAOA in prostate cancer cells led to decreased expression of FOXA1.This MAOA may play different roles at different stages of NED by acting through FOXA1.Conclusions Both MAOA and FOXA1 levels showed increasing,then decreasing,trends during NED.The expression of MAOA affected the level of FOXA1,and MAOA/FOXA1 may play a dynamic regulatory role in the NED process.

Objective:To seek any relationship between the single nucleotide polymorphisms (SNPs) of the apolipoprotein E (ApoE) gene and blood lipid sensitivity to high-intensity interval training (HIIT).Methods:Two hundred and thirty Han Chinese college students (104 males and 126 females) who were not majoring in sports were recruited to perform a 28-minute high-intensity interval workout three times per week for 12 weeks. Before and after the intervention, blood levels of triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) were measured. The subjects′ DNA was genotyped to obtain SNP loci, and a linear regression model was constructed to quantify any association between ApoE genotypes and phenotypes.Results:(1) A total of 21 SNP loci were identified associated with ApoE genes, one of which (rs7412) was found to be correlated with the training effect on blood lipids. (2) The initial TT and LDL-C values of carriers of the T allele of gene rs7412 (individuals with the CT + TT genotypes) were, on average, significantly lower than those of CC genotype individuals. However, no significant differences in the initial TG and HDL-C values among different genotypes were observed. (3) After the training the average LDL-C levels among the ApoE rs7412 polymorphic groups had changed significantly, with a significantly greater decrease observed among the carriers of the T allele compared with those of CC genotype.Conclusions:ApoE polymorphism may be significantly associated with TT and LDL-C values in Han Chinese youth, with carriers of the T allele tending to display lower levels than those of CC genotype. The polymorphism of ApoE gene rs7412 may be related to LDL-C reduction through HIIT, with carriers of the T allele more sensitive to such training.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:The outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for myelodysplastic syndromes-evolved acute myeloid leukemia (MDS-AML) were explored.Methods:A retrospective review was conducted for 54 patients with MDS-AML treated with allo-HSCT in the Institute of Hematology and Blood Disease Hospital from January 2018 to August 2022. The clinical effects after transplantation were observed, and the related risk factors influencing prognosis were explored.Results:Of the total 54 patients, 26 males, 28 females, and 53 patients achieved hematopoietic reconstruction. After a median follow-up of 597 (15-1 934) days, the 1 year overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (CIR) and non-relapse mortality (NRM) rate were 75.8%±5.8%, 72.1%±6.1%, 12.7%±4.9%, and 17.1%±5.2%, respectively. The 3 year estimated OS, DFS, CIR, and NRM rates were 57.8%±7.5%, 58.1%±7.2%, 23.2%±6.6%, and 23.7%±6.6%, respectively. The cumulative incidence of acute graft-versus-host disease (aGVHD) was 57.5%±6.9%, and the cumulative incidence of chronic graft-versus-host disease (cGVHD) was 48.4%±7.7%. Hematopoietic cell transplantation comorbidity index (HCT-CI) before transplantation was ≥2, minimal residual disease (MRD) was positive on the day of reconstitution, grade Ⅲ/Ⅳ aGVHD, bacterial or fungal infection and no cGVHD after transplantation were adverse prognostic factors for OS ( P<0.05). COX regression model for multivariate analysis showed that HCT-CI score before transplantation, bone marrow MRD on the day of response, grade Ⅲ or Ⅳ aGVHD, and cGVHD after transplantation were the independent adverse factors for OS ( P=0.001, HR=6.981, 95% CI 2.186-22.300; P=0.010, HR=6.719, 95% CI 1.572-28.711; P=0.026, HR=3.386, 95% CI 1.158-9.901; P=0.006, HR=0.151, 95% CI 0.039-0.581) . Conclusion:For patients with MDS-AML and high risk of relapse, allogeneic transplantation must be considered as soon as possible. The enhanced management of post-transplantation complications and maintenance treatment should be provided whenever possible after transplantation.

Objective:To explore the application value of real-time shear wave elastography(SWE)and ultrafast pulse wave velocity(UFPWV)techniques in assessing carotid artery stiffness of patients with gouty arthritis(GA).Methods:A total of 80 GA patients admitted to the First People's Hospital of Yibin from August 2022 to July 2023 were selected as GA group.Among of them,24 cases combined with bone erosion who were confirmed by imaging examination,and 56 cases did not combine with bone erosion.In addition,a total of 40 healthy individuals,who underwent physical examinations in our hospital during the same period,were selected as the healthy control group.SWE and UFPWV were used to detect the maximum,minimum and mean values of Young's modulus values of the vessel wall of common carotid artery,and the pulse wave velocity at the beginning of systole(PWVBS)and pulse wave velocity at the end of systole(PWVES)of the vessel wall of common carotid artery of all subjects,and to assess the hardness of circumferential and longitudinal vessel wall of common carotid artery of them.The differences in Young's modulus values,PWVBS and PWVES between two groups were compared.And then,the correlations between bone erosion and Young's modulus values,PWVBS,PWVES of GA patients were further analyzed.Results:The maximum,minimum,mean values,PWVBS and PWVES in the GA group were respectively(78.80±12.38)kPa,(57.83±7.42)kPa,(67.67±8.38)kPa,(7.06±0.59)m/s and(9.50±0.63)m/s,which were significantly higher than those in the healthy control group(t=11.066,8.216,11.751,14.159,19.118,P＜0.05).The maximum,minimum,mean values,PWVBS and PWVES of GA patients with bone erosion were respectively(82.95±6.37)kPa,(59.59±5.29)kPa,(72.18±7.62)kPa,(7.37±0.43)m/s,(10.43±0.47)m/s,which were significantly higher than those[(77.01±5.32)kPa,(57.08±4.73)kPa,(65.73±4.54)kPa,(6.92±0.39)m/s and(9.10±0.41)m/s]of GA patients without bone erosion,the differences were significant(t=4.309,2.099,4.699,4.586,12.720,P＜0.05).Spearman correlation analysis showed that there was significant correlations between maximum,minimum,mean values,PWVBS,PWVES and the combined bone erosion in GA patients(r=0.602,0.421,0.682,0.647,0.732,P＜0.05).Conclusion:SWE and UFPEV techniques can evaluate the hardness of vascular wall of GA patients,and the hardness of circumferential and longitudinal vessel wall of common carotid artery of GA patient is higher than that of healthy person,and the hardness of circumferential and longitudinal vessel wall of common carotid artery of GA patient with bone erosion is higher.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.
