Objective:To explore the experience of self-management dilemma ofadults with emerging ankylosing spondylitis, and to provide reference for the construction of self-management intervention strategies for emerging adults with ankylosing spondylitis.Methods:Descriptive phenomenology was used to conduct in-depth interviews with 14 adults with emerging ankylosing spondylitis in the Rheumatology and Immunology Department of Drum Tower Hospital Affiliated to Medical College of Nanjing University from August 2022 to March 2023. The interview data were analyzed by Colaizzi′s seven-step analysis method.Results:A total of 14 patients completed the interview,10 males, 4 females, aged 21-30 years. In adults with emerging ankylosing spondylitis, there were dilemmas of role maladjustment and disease management disorder, including role maladjustment of disease management and social role maladjustment. Barriers to disease management included weak self-management awareness, insufficient support for self-management information, inadequate self-management skills, and poor compliance with self-management behaviors.Conclusions:The role adaptation and self-management ability of adults with emerging ankylosing spondylitis are seriously inadequate. It is urgent to construct health management strategies for adults with emerging ankylosing spondylitis to help them improve the level of role adaptation and disease management.

Objectives:To evaluate the valvular and cardiac function,cardiac reverse remodeling at 6-month after transcatheter edge-to-edge repair(TEER)for patients with functional and degenerative mitral valve regurgitation,and summarize the experience of echocardiography application. Methods:The clinical data of 93 patients with moderate to severe mitral regurgitation(MR)treated with TEER and completed 6-month follow-up in Yunnan Fuwai Cardiovascular Hospital from July 2022 to February 2023 were retrospectively analyzed.Patients were divided into functional mitral regurgitation(FMR)and degenerative mitral regurgitation(DMR)groups according to MR etiology.The valve characteristic parameters,as well as valvular function,chamber volume and cardiac functional parameters before and at 6 months after operation were compared.The key points of echocardiography application were summarized. Results:Among all patients,71 were FMR and 22 were DMR.There were differences in valve structure between the two groups.Mitral TEER were successfully accomplished and all patients completed 6-month follow-up.The key points of echocardiography application included:valve structure analysis,atrial septal puncture location,device delivery process monitoring and image optimization during clamping process.The mitral regurgitation grade and NYHA grade were significantly improved in all patients at 6 months after TEER(P<0.05),and the mean mitral valve pressure gradient was higher than that before operation(P<0.05).Left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and left atrial volume index in FMR group were significantly decreased(P<0.05),while left ventricular and left atrial volume in DMR group remained unchanged(P>0.05).There were no significant changes in left ventricular ejection fraction and left ventricular global strain in both groups during the observation period(P>0.05).The changes of LVEDV and LVESV before and after operation were more significant in FMR group than those in DMR group(P<0.05). Conclusions:Mitral TEER can reduce the degree of regurgitation and improve cardiac function in the early postoperative period for moderate and severe MR patients with different etiologies.There are differences in preoperative valve structure and postoperative cardiac reverse remodeling between FMR and DMR patients.Echocardiography is an important imaging technique for the evaluation and monitoring process before,during and post mitral TEER.

Objective:To evaluate the effect of autologous hematopoietic stem cell transplantation (ASCT) on the treatment of relapsed/refractory multiple myeloma (RRMM) with chimeric antigen receptor T cell (CAR-T) therapy.Methods:A retrospective cohort study. The clinical data of 168 patients with RRMM who underwent CAR-T therapy at the Department of Hematology, Xuzhou Medical University Hospital from 3 January 2020 to 13 September 2022 were analyzed. Patients were classified into a transplantation group (TG; n=47) and non-transplantation group (NTG; n=121) based on whether or not they had undergone ASCT previously. The objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and the levels of CD3, CD4, CD8, CD19, CD56 and natural killer (NK) cells before CAR-T infusion were analyzed by χ2 test, Kaplan-Meier method and independent sample t-test. Results:Among 168 patients with RRMM, 98 (58.3%) were male. The median age of onset was 57 (range 30-70) years. After CAR-T therapy, the ORR of patients was 89.3% (92/103) in the NTG and 72.9% (27/73) in the TG. The ORR of the NTG was better than that of the TG ( χ2=5.71, P=0.017). After 1 year of CAR-T therapy, the ORR of the NTG was 78.1% (75/96), and that of the TG was 59.4% (19/32). The ORR of the NTG was better than that of the TG ( χ2=4.32, P=0.038). The median OS and PFS in the NTG were significantly longer than those in the TG (OS, 30 vs. 20 months; PFS, 26 vs. 12 months; both P<0.05). The CD4 level before CAR-T infusion in the TG was significantly lower than that in the NTG (25.65±13.56 vs. 32.64±17.21; t=-2.15, P=0.034), and there were no significant differences in the counts of CD3, CD8, CD19, CD56, and NK cells between the TG and NTG (all P>0.05). Conclusion:Among patients suffering from RRMM who received CAR-T therapy, patients who did not receive ASCT had significantly better outcomes than those who had received ASCT previously, which may have been related to the CD4 level before receiving CAR-T therapy.

We report the first in man experience of robotic assisted transcatheter edge-to-edge repair(TEER)with pure Trans-esophageal echocardiography-guidance.A 55y female was diagnosed with heart failure with 4+functional MR despite optimal medical treatment.TEER procedure was planned with robotic assistance.After guiding catheter,the robotic system was incorporated into the TEER device to replace manual operation.Under pure echo-guidance one clip was successfully placed in A2/P2 region with marked reduction of MR to 1+.Patient was discharged without complication.

Mitral regurgitation (MR) is the most common valvular heart disease, however, majority of patients are not suitable for open heart surgery due to comorbidity such as organ and heart dysfunction. Transcatheter edge-to-edge mitral valve repair has become an effective treatment option for high-risk patients with MR. Two patients were enrolled in this study inlcuding one 60-year degenerative mitral regurgitation patient and one 72-year functional mitral regurgitation patient. Transcatheter repair procedure was successfully done for the two patients without postoperative complication.

Objective:To investigate the clinical characteristics, efficacy and prognostic influencing factors of IgD multiple myeloma (MM) in the new immunotherapy era.Methods:The clinical data of 29 patients diagnosed with IgD MM in the Affiliated Hospital of Xuzhou Medical University from March 2014 to February 2021 were retrospectively collected. The clinical characteristics, treatment regimens and efficacy, especially the efficacy of new drugs and immunotherapy for the disease were analyzed. Kaplan-Meier method was used to analyze the overall survival (OS) and progression-free survival (PFS). Multivariate Cox proportional risk model was used for analysis of prognostic influencing factors.Results:The median age of patients was 58 years. There were 20 cases (69.0%) below 65 years, 12 cases (41.4%) of complicated with stomach function damage, 6 cases (20.7%) of extramedullary invasion. All patients were treated with combined therapy containing proteasome inhibitor bortezomib in the first-line therapy, and the overall response rate was 82.8% (24/29). Among 21 relapsed/refractory patients, 12 patients were treated with the second-line or above treatment regimen chimeric antigen receptor T cell (CAR-T) immunotherapy, including 9 cases achieving very good partial remission (VGPR) or above; 5 patients were treated with the new drug daratozumab, including 1 case achieving complete remission (CR). The median OS time of 29 patients was 48 months (95% CI 17-79 months), the median PFS time after the first-line treatment was 9 months (95% CI 3-15 months), and the median PFS time after the second-line treatment was 11 months (95% CI 1-21 months). Multivariate Cox regression results showed that CAR-T therapy is an independent influencing factor of the prognosis of relapsed/ refractory IgD MM patients ( HR = 0.094, 95% CI 0.019-0.473, P = 0.004). Conclusions:IgD MM patients are characterized with lower onset age, more renal function damage and a high incidence of extramedullary invasion. The first-line therapy containing proteasome inhibitor has a better short-term efficacy, and CAR-T therapy can improve the remission rate and survival rate of relapsed/refractory IgD MM to a certain extent.

Objective:To investigate the differential expression profile of circular RNA (circRNA) in high glucose-cultured human retinal vascular endothelial cells (HRVECs).Methods:HRVECs were divided into high glucose group, normal control group and hypertonic control group, and were cultured in 25 mmol/L glucose medium, 5.5 mmol/L glucose medium and 19.5 mmol/L mannitol+ 5.5 mmol/L glucose medium for 24 hours accordingly.The differentially expressed circRNA molecules between high glucose group and normal control group were screened by circRNA microarray analysis.The expression of the most significant differentially expressed circRNAs in different groups was verified by real-time quantitative PCR.The possible microRNA (miRNA) targets were analyzed through the Circular RNA Interactome database.Results:It was found that 448 circRNAs were differentially expressed (FC≥1.5 or FC≤0.67, P<0.05) in high glucose-cultured HRVECs, among which 182 were up-regulated and 266 were down-regulated.The top 3 significantly up-regulated circRNAs were hsa_circ_0002938, hsa_circ_0008036, and hsa_circ_0001946, and the top 3 significantly down-regulated circRNAs were hsa_circ_0035277, hsa_circ_0008344, and hsa_circ_0001874.Compared with normal control group and hypertonic control group, the relative expressions of top 3 up-regulated circRNAs were significantly enhanced and the relative expressions of top 3 down-regulated circRNAs were significantly reduced in high glucose group, showing statistically significant differences (all at P<0.05).No significant difference was found in the differentially expressed circRNAs between normal control group and hypertonic control group (all at P>0.05). Conclusions:CircRNAs are differentially expressed in high glucose-cultured HRVECs, and the differentially expressed circRNAs may be involved in the regulatory mechanism of diabetic retinopathy.

Objective:To investigate the safety and efficacy of transcatheter genicular artery embolization (GAE) for moderate to severe knee osteoarthritis (KOA).Methods:This prospective study included 13 patients (17 knees) with KOA who were treated with GAE from October 2020 to March 2021. The Kellgren-Lawrence (K-L) grade was 2-3 for 11 knees, and 4 for 6 knees. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and the Whole-Organ Magnetic Resonance Imaging Score (WORMS) assessments were performed for all the subjects before operation. The success rate, clinical efficacy and complications were recorded after operation. Clinical outcomes were evaluated at 1 day, 1week and 1, 3, 6 months after the operation.Results:The success rate of GAE in 17 cases was 100%, and the success rate of target artery superselection was 98.4%(63/64). The baseline WOMAC pain score was 11(10, 13) and total score was 44(38, 58) for 17 knees. Post-operation follow-up WOMAC pain score were 4(3, 7), 2(1, 5), 2(1, 6) and 4(2, 6) at 1 day, 1 week, 1 month, and 3 months. Post-operation follow-up WOMAC total score were 22 (15, 34),20 (12, 24),17 (12, 26) and 20 (12, 31) at 1 day, 1 week, 1 month, and 3 months. There were 16 knees with 6 month follow-up assessment, with the WOMAC pain score of 2.5(2, 5), and the total score of 15(12, 26). Significant difference was found in the WOMAC pain score between baseline and the 1 day, 1 week, 1, 3 and 6 months follow up ( Z=-3.631, -3.623, -3.622, -3.622, -3.532, all P<0.001); also, the total score was statistically significant different between the baseline and the 1 day, 1 week, 1, 3 and 6 months follow up ( Z=-3.639, -3.634, -3.646, -3.527, -3.532, all P<0.001). At 3 months follow-up, there was 1 knee recognized clinical failure. Post-operative adverse reaction in this group included skin ecchymosis in femoral artery puncture area ( n=3), knee joint stiffness and pain within 1 week ( n=4),and clanging joints during postoperative activities ( n=6). Conclusion:GAE is a feasible and safe procedure with obvious short-term curative effect, which can alleviate pain symptoms and improve restricted movement in patients with KOA.

Objective:To investigate the status of hope level, psychological consistency and self-concept of clinical nurses and to analyze the mediating effect of hope level between psychological consistency and self-concept of clinical nurses.Methods:Using the cross-sectional survey method, the convenient sampling method was used to select 920 clinical nurses from 3 Class Ⅲ Grade A hospitals in Henan Province as research objects from March to April 2020. General data questionnaire, Herth Hope Index (HHI) , Sense of Coherence-13 (SOC-13) and Nurses' Self Concept Questionnaire (NSCQ) were used to investigate. The structural equation model was used to analyze the mediating effect of hope level between psychological consistency and self-concept of nurses. In this study, a total of 920 questionnaires were distributed and 853 effective questionnaires were collected, with an effective recovery rate of 92.72%.Results:The total score of HHI of 853 clinical nurses was (35.05±6.28) , the total score of SOC-13 was (52.52±8.44) and the total score of Nurses' Self Concept Questionnaire was (221.76±34.56) . The results of Pearson correlation analysis showed that psychological consistency of clinical nurses was positively correlated with hope level and self-concept ( P<0.05) . The results of the structural equation model showed that psychological consistency has direct and indirect predictive effects on self-concept of nurses, and the path coefficients were respectively 0.31 and 0.14. Hope level had a mediating effect between psychological consistency and self-concept. Conclusions:Hope level plays a mediating role between psychological consistency and self-concept of nurses. Nursing managers should take effective measures to improve psychological consistency and hope level of nurses, so as to improve self-concept level of nurses to promote their mental health.

Objective:To investigate the effectiveness of scanning glucose monitoring system in dawn phenomenon of patients with type 2 diabetes mellitus (T2DM) based on continuous glucose monitoring system (CGMS) .Methods:A total of 45 patients with T2DM hospitalized in the Endocrine Department of Xinxiang Central Hospital from June 2019 to June 2020 were selected as the research subjects by convenience sampling method. All selected patients were asked to wear the scanning glucose monitoring system after admission, and then the CGMS for continuous glucose monitoring after 48 hours. The scanning glucose monitoring system and the CGMS were taken off at the same time after 72 hours. The blood glucose analysis report of the same period was checked to determine whether the dawn phenomenon occurred. The consistency to determine dawn phenomenon was analyzed between CGMS and scanning blood glucose monitoring by Kappa test. According to the CGMS judgment results, the receiver operating characteristic curve (ROC) of the scanning blood glucose monitoring system was drawn to evaluate the optimal tangent value of the night blood glucose for predicting dawn phenomenon and the next day fasting blood glucose for evaluating dawn phenomenon.Results:Among the 45 study subjects, there was no statistical difference in determining the incidence of dawn phenomena between CGMS and scanning glucose monitoring system [55.56% (25/45) vs. 46.67% (21/45) , χ 2=0.711, P>0.05]. Consistency analysis showed that Kappa value was 0.895, and the consistency of CGMS and scanning glucose monitoring system in judging dawn phenomenon was good (Kappa=0.895, 95% CI 1.130-4.883, P<0.01) . The optimal tangent value of night blood glucose for predicting dawn phenomenon was 8.31 mmol/L, and the optimal tangent value of the next day fasting blood glucose for evaluating dawn phenomenon was 7.25 mmol/L. The value of the area under the ROC curve were 0.729 and 0.803 respectively. Conclusions:Scanning blood glucose monitoring can accurately judge the dawn phenomenon. When the night blood glucose value is 8.31 mmol/L, it indicates that the dawn phenomenon may occur. When the next day's fasting blood glucose value is 7.25 mmol/L, it indicates that the dawn phenomenon may already occur.
