Objective To observe the effect of Huoxin pill （concentrated pill） combined with Baduanjin on the prognosis of patients with acute myocardial infarction complicated by percutaneous coronary intervention （PCI）. Methods 120 patients with acute myocardial infarction complicated with heart failure who received emergency interventional treatment in our hospital from January 2022 to January 2023 were randomly divided into western medicine treatment group and Traditional Chinese Medicine （TCM）comprehensive treatment group. Western medicine treatment: standard western medicine treatment + five prescriptions for cardiac rehabilitation; based on western medicine treatment, Huoxin pill （concentrated pill） combined with Baduanjin therapy was added to the TCM comprehensive treatment group, and the follow-up was 6 months. The observed indexes were exertion angina pectoris scale, Chinese Medicine Syndrome Scale, Chinese medicine syndrome treatment effect evaluation, 6-minute walking test （6MWT）, left ventricular ejection fraction （LVEF）, and brain natriuretic peptide precursor （pro-BNP）. Results Sixty patients were enrolled in the two groups respectively. During the treatment, 2 cases fell off in the western medicine treatment group and 8 cases fell off in the TCM comprehensive treatment group, and a total of 110 cases were enrolled in the group. Compared with the western treatment group, TCM combined therapy significantly improved angina pectoris scale score, TCM Syndrome Scale score, pro-BNP, LVEF and 6MWT （P<0.001）. There were no significant differences in blood routine, liver and kidney function, potassium, blood glucose, blood lipids and cardiac Troponin I （cTnI） between the two groups （P>0.05）. No adverse cardiovascular events occurred during the entire treatment period in both groups. Conclusion Huoxin pill （concentrated pill） combined with Baduanjin was more effective than western therapy in improving LVEF, 6MWT distance, exercise tolerance and cardiac function in patients with acute myocardial infarction complicated with heart failure.

Objective:To construct a nursing intervention program based on dyadic coping theory for patients with spinal cord injury (SCI) and their spouses, and to explore the effects of the program on improving their coping abilities and quality of life.Methods:The nursing intervention program was developed through literature review, expert panel discussions, and the Delphi method, guided by dyadic coping theory. Using convenience sampling, 90 pairs of patients with SCI and their spouses who underwent surgery in the Department of Orthopedics at the Second Affiliated Hospital of Anhui Medical University from January to August 2023 were selected. Participants were randomly divided into control group ( n=46) and observation group ( n=44). The control group received standard nursing care, while the observation group received the dyadic coping-based nursing intervention program in addition to standard care for three months. Both groups were assessed at admission and three months post-intervention using the Dyadic Coping Inventory (DCI), WHO Quality of Life-BREF (WHOQOL-BREF), and Family Adaptability and Cohesion Evaluation Scale (FACESⅡ) . Results:After three months, the DCI scores for patients and spouses in the observation group were (117.80±0.88) and (121.50±3.29), respectively. The WHOQOL-BREF scores for the patients and spouses were (80.50±1.77) and (81.09±1.58), respectively. The FACESⅡ scores for the patients were (65.70±0.95) and (48.68±1.03), respectively, and for their spouses were (67.02±0.88) and (49.55±1.27), respectively. All scores were significantly higher in the observation group compared to the control group ( P<0.05) . Conclusions:The nursing intervention program based on dyadic coping theory effectively improves the dyadic coping abilities, quality of life, and family functioning of patients with SCI and their spouses.

BACKGROUND:Recent studies have found that long non-coding RNAs (lncRNAs) can regulate stem cel proliferation and differentiation. But it is unclear that how lncRNA NR_033474 regulate stem cel proliferation and cel cycle. OBJECTIVE:To investigate the effect of lncRNA NR_033474 on the proliferation and cel cycle regulation in C3H10T1/2 mesenchymal stem cel s after the NR_033474 overexpressed by lentivirus, and to study the possible regulation mechanism of NR_033474 on mesenchymal stem cel s. METHODS:LncRNA NR_033474 was cloned into a lentivirus vector. Lentivirus particles were infected into C3H10T1/2 cel s to upregulate the expression of NR_033474. The NR_033474 expression level was detected by real-time PCR. Compared with the empty lentivirus vector, the proliferation of C3H10T1/2 cel s which overexpressed NR_033474 was detected by cel counting assay and cel cycle was detected using flow cytometry. The expression of cel cycle-associated proteins such as CDK1, Cyclin B1, Cyclin D1 and P53 were detected by western blot assay. RESULTS AND CONCLUSION:Compared with the control group, lncRNA NR_033474 in C3H10T1/2 cel s which overexpressed NR_033474 was increased by about 100 times (P<0.01), and the proliferation of C3H10T1/2 cel s was significantly inhibited after NR_033474 overexpression by lentivirus (P<0.05). In addition, flow cytometry showed that C3H10T1/2 cel s overexpressing NR_033474 were arrested in G2/M phase compared to the control group. Western blot showed that the expression levels of CDK1 and Cyclin B1 were downregulated, while there were no changes in Cyclin D1 and P53 expression. To conclude, these findings suggest that the NR_033474 overexpression significantly inhibits the cel growth of C3H10T1/2 cel s, at least in part, through induction of cel cycle arrest at G2/M phase.

OBJECTIVE: The aim of this study was to evaluate the safety and effectiveness of balloon sinuplasty, and to summarize the main points of its use. METHOD: Fifteeen patients (41 sinuses) were offered treatment with a new technique of balloon sinuplasty and followed for 3 to 6 months after surgery, including "balloon-only" patients and "hybrid" patients. Effectiveness was evaluated by endoscopic examination and computed tomographic (CT) scan. The effect of the operation was tested by the Lund-Mackay CT scores, and the patient's subjective symptoms were tested by the sino-nasal outcome test-20 (SNOT-20) to evaluate postoperative condition. RESULT: Fifteeen patients (41 sinuses) were followed after surgery, including 9 "balloon-only" patients and 6 "hybrid" patients. No unanticipated adverse effects were noted in any patients. Endoscopic examination showed the sinus ostium was opening well, and CT scan showed the lesions apparently disappeared. Lund-Mackay CT scores showed that all patients postoperative scores were significantly improved from baseline at 3 months and 6 months. SNOT-20 showed that all patients postoperative scores were significantly improved from baseline at 3 months and 6 months. There was no significant difference between the "balloon-only" patients and "hybrid" patients. Operation curative effect is very confirmed, and subjective symptoms improved significantly. CONCLUSION Balloon sinuplasty can not only open nasal sinus effectively, but also preserve normal tissue structure and mucous membrane of nasal cavity and nasal sinus. Balloon sinuplasty appears to be a safe, effective and minimally invasive treatment option to relieve sinus ostial obstruction. Patients who received balloon catheter sinusotomy in endoscopic sinus surgery had significant improvement after surgery. Balloon sinuplasty can also be combined with the endoscopic sinus surgery to achieve a better therapeutic effect. It is worth of clinical promotion and application.

BACKGROUND:Recent studies have found that stem cellpluripotency and differentiation is regulated by many long non-coding RNAs (LncRNAs). The expression and effect of LncRNA AK089560 during differentiation of stem cells is unclear. OBJECTIVE:To investigate the expression of LncRNA AK089560 in mesenchymal stem cells C3H10T1/2 undergoing osteogenic and adipogenic differentiation. METHODS:Osteogenic differentiation of mesenchymal stem cells C3H10T1/2 was induced by recombinant human bone morphogenetic protein-2 and evaluated using alkaline phosphatase staining. The adipogenic differentiation of mesenchymal stem cells C3H10T1/2 was induced by three factors (dexamethasone, indomethacin and insulin) and evaluated by oil red O staining. The dynamical expression of LncRNA AK089560 was detected by qRT-PCR assay. The AK089560 secondary structure was predicted using RNAfold software. The relationship between AK089560 and neighboring protein-coding genes was analyzed using UCSC genome browser and visualized by fancyGENE online software. RESULTS AND CONCLUSION:Over 70%of C3H10T1/2 cells were positive for alkaline phosphatase after osteogenic induction and more than 80%of the cells positive for oil red O staining after adipogenic induction. qRT-PCR results showed that the expression of LncRNA AK089560 at days 2, 4, 6 of both osteogenic and adipogenic differentiation was significantly decreased compared with the control group (P<0.05). Bioinformatics analysis showed that there was a stem-loop structure for AK089560 and sense overlap relationship between AK089560 and protein-encoding gene Sema3a. These findings indicate that LncRNA AK089560 expression is reduced during osteogenic differentiation and adipogenic differentiation, showing that AK089560 may be involved in regulating the multi-directional differentiation of stem cells.
