Objective To explore the effect of lyophilized recombinant human brain natriuretic pep-tide(rhBNP)combined with furosemide on serum myocardial enzymes levels in elderly patients with acute heart failure(AHF).Methods A total of 162 elderly AHF patients admitted in our de-partment from January 2020 to November 2023 were recruited,and randomly divided into furose-mide group and furosemide+rhBNP group,with 81 cases in each group.The remission times of clinical symptoms were observed in the two groups.The score of heart failure degree,disease se-verity score,echocardiographic indicators and serum biochemical indicators before and in 2 weeks after treatment were studied and compared between the two groups.These indicators included left ventricular end-systolic diameter(LVESD),left ventricular ejection fraction(LVEF),left ventri-cular end-diastolic diameter(LVEDD),stroke volume(SV),and levels of α-hydroxybutyrate de-hydrogenase(α-HBDH),creatine kinase(CK),creatine kinase isoenzyme(CK-MB),lactate dehy-drogenase(LDH)and micro ribonucleic acid-181b(miR-181b),transient receptor potential C1(TRPC1)and growth differentiation factor 15(GDF-15).Results The remission time of short-ness of breath and time of edema subsidence after treatment were significantly shorter in the furo-semide+rhBNP group than the furosemide group(3.31±0.62 d vs 5.18±1.08 d,3.86±0.82 d vs 6.08±1.19 d,P＜0.01).After treatment,the heart failure degree score,APACHE Ⅱ score,LVEDD,LVESD,and levels of LDH,CK,CK-MB,α-HBDH,TRPC1 and GDF-15 were obviously declined,while LVEF,SV and miR-181b level were notably risen in both groups when compared to the levels before treatment(P＜0.05).Conclusion rhBNP combined with furosemide can shorten the duration of AHF symptoms in the elderly patients.It can not only relieve the disease condition of heart failure,but also improve serum myocardial enzyme indicators,alleviate the my-ocardial injury and protect the heart in the patients.

Outpatient humanistic care refered to providing a full process of caring medical services to outpatients. In order to standardize the human caring services for outpatients in medical institutions, promote the comprehensive service level of outpatient services, and improve the patient′s medical experience, Chinese Association for Life Care issued the group standard of Management Norms for Human caring of Outpatients in April 2023. This standard clarified the relevant terms and definitions of human caring for outpatients, specified the basic requirements for human caring, the humanistic quality and care responsibilities of outpatient staff, the outpatient care environment and facilities, the outpatient care process and measures, and quality management. It designed standardized and personalized full process care service norms, providing references for medical institutions at all levels to promote the development of human caring for outpatients.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To investigate the effect and molecular mechanism of high concentration of IL-17A on osteoclast differentiation by inhibiting autophagy of osteoclast precursor cells through PI3K/Akt pathway.Methods:With RANKL (50 ng/ml) inducing osteoclast precursor cells (osteoclast we cells, OCPs), osteoclast differentiation model is set up. In osteoclast differentiation model of high levels of IL-17A (100 ng/ml), RAW264.7 cells were divided into negative control CTR-N group, CTR-R group with RANKL, IL-17A group, IL-17A+LY294002 group. BMMs were divided into negative control CTR-N group with M-CSF, CTR-R group, IL-17A group and IL-17A+LY294002 group with M-CSF and RANKL. IL-17A was applied to OCPs, and tartrate-resistant acid phosphatase (TRAP) staining was used to observe the number of osteoclast differentiation. The number of autolysosomes was observed under transmission electron microscope. RAW264.7 was treated with IL-17A. Western blot was used to detect the relative expression levels of p-Akt/Akt, p-mtor/mTOR, p-PI3K/PI3K, p-ULK1/ULK1, Cleaved-caspase3/caspase3, Beclin1/β-actin. The apoptosis rate of RAW264.7 cells treated with IL-17A was detected by flow cytometry. OCPs were treated with IL-17A and PI3K inhibitor LY294002, and TRAP staining was used to observe the number of osteoclast differentiation.Results:The TRAP staining showed that the positive ratio for RAW264.7 cells CTR-N group, CTR-R group, IL-17A group was 1.33%±0.58%, 100%±3.01%, 51.11%±4.02% with that of IL-17A significantly lower than CTR-R group ( t=16.970, P<0.05). The positive rates of BMMs in the CTR-N group, CTR-R group and IL-17A group were 1.67%±0.58%, 100%±1.01% and 50.33%±2.52%, respectively, with that of IL-17A group significantly lower than CTR-R group ( t=31.770, P<0.05). Transmission electron microscopy showed that the number of autophagosomes in RAW264.7 cells in CTR-R group and IL-17A group were 3.67±1.53 and 0.67±0.58, respectively, with significant difference between the groups ( t=3.182, P<0.05). While in BMMs cells CTR-R group and IL-17 the numbers of autophagosome were 3.00±1.00 and 0.33±0.58 with significant difference ( t=4.000, P<0.05); Western blot results showed 0.69±0.03、0.69±0.13、1.47±0.13、0.78±0.04、0.66±0.10、0.82±0.03 for RAW264.7 cells CTR-R group Akt/Akt, p-mTOR/mTOR, p-PI3K/PI3K, p-ULK1/ULK1, Cleaved caspase3/caspase3, Beclin1/β-Actin and 0.89±0.04、1.14±0.18、1.87±0.04、0.53±0.09、0.93±0.02、0.54±0.03 for RAW264.7 cells IL-17A group p-Akt/Akt, p-mTOR/mTOR, p-PI3K/PI3K, p-ULK1/ULK1, Cleaved caspase3/caspase3, Beclin1/β-Actin with significant difference ( t=6.708; t= 3.497; t=5.424; t=4.542; t=4.638; t=11.220, all P<0.05); Flow cytometry detection showed that in CTR-R group, IL-17A RAW264.7 cells apoptosis rates of group A were 6.92%±0.62%, 12.12%±0.69%, with significant difference between the two groups ( t=9.747, P<0.05); After using LY294002 TRAP staining, it showed a positive result of 9.00%±2.00%, 158.33%±3.51%, 100%±2.65% and 128.99%±4.01% for CTR-N, CTR-R, IL-17A and IL-17A+LY294002 in RAW264.7 cells respectively with significant difference between IL-17A+LY294002 group and the IL-17A in group A ( t=10.470, P<0.05).

Objective:To investigate and summarize the early management experience of 22 patients with end-stage heart failure(ESHF) who underwent left ventricular assist device(LVAD) implantation in an intensive care unit(ICU) in a single center.Methods:Data of 22 patients with ESHF treated with LVAD in the ICU of TEDA International Cardiovascular Hospital from September 2020 to August 2022 were retrospectively analyzed. There were 16 males and 6 females, aged from 20 to 67 years old, with a mean age of(51.0±13.3)years old. There were 21 cases with dilated cardiomyopathy, 1 case with ischemic cardiomyopathy, 6 cases with tricuspid regurgitation, 1 case with intra-aortic balloon pump for cardiogenic shock, and 5 cases with cardiac resynchronization therapy for arrhythmia. After the operation, all patients received restricted fluid therapy, a " stepwise" anticoagulation strategy, and strict blood pressure management. The postoperative complications and treatment process were reviewed, the treatment and management experience were summarized, and the prognosis of the patients was statistically analyzed.Results:All 22 patients survived within 90 days after surgery, and 21 patients(95.5%) recovered well, the pump works fine and there was no hemolysis and thrombosis of LVAD. Major complications included: 1 case of severe pneumonia(4.5%), 2 cases of pericardial tamponade(9.1%), 1 case of intracerebral hemorrhage(4.5%), 1 case of mediastinal infection(4.5%), 5 cases of positive occult blood in gastric juice(22.7%), no cases of right ventricular failure、aortic insufficiency and cerebral infarction. The duration of postoperative mechanical ventilation was 17(8.5, 51.5) h, and the ICU stay was 14(10, 27) days.Conclusion:LVAD is another effective treatment for patients with ESHF in addition to heart transplantation. Good postoperative blood pressure control, " stepwise" anticoagulation strategy and " restrictive" fluid management can reduce postoperative complications in the early phase of post-operation, which is crucial for the prognosis of patients with LVAD.

Objective:To investigate and evaluate the efficacy of HeartCon left ventricular assist device (LVAD) in the treatment of adult patients with end-stage heart failure (ESHF).Methods:A prospective and observational study was conducted. Patients with ESHF who underwent LVAD implantation in the department of cardiac surgery of Teda International Cardiovascular Hospital from September 2020 to August 2021 were selected. The left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) classification, N-terminal pro-B type natriuretic peptide (NT-proBNP), and six minute walk distance (6MWD) before operation and 90 days after operation were compared. The incidence of equipment failures and major adverse events within 90 days after operation were recorded.Results:A total of 20 patients with ESHF were included, with 15 males and 5 females. Patients' age ranged from 20 to 67 years old, with an average of (50.2±13.6) years old. The range of body weight was 49.8-106.1 kg, with an average of (67.9±15.5) kg, and the body surface area (BSA) was from 1.49 to 2.32 m 2, with an average of (17.6±0.22) m 2. The operation process of all the patients were successful. The length of hospital stay ranged from 33 to 90 days, and the average was 56.0 (42.8, 75.0) days. Complications within 90 days after operation as follows, 2 cases with pericardial tamponade (10%), 1 case with cerebral hemorrhage (5%), 1 case with mediastinum infection (5%), 3 cases with acute renal injury (AKI, 15%), 5 cases with gastrointestinal bleeding (25%). There were no mechanical failure of LVAD and hemolysis events, right ventricular failure (RVF), cerebral infarction and death occurred. Compared with preoperative, the LVEDD significantly decreased (mm: 67.50±13.98 vs. 77.40±9.73), LVEF significantly increased (%: 34.80±9.76 vs. 22.70±5.62), NT-proBNP significantly decreased (ng/L: 2 028.65±1 752.05 vs. 4 796.45±4 355.40), 6MWD significantly increased (m: 385.20±144.12 vs. 85.81±63.50) at 90 days after operation, and the differences were statistically significant (all P < 0.05). 18 cases (90%) of the 20 patients reached NYHA classification Ⅰ and 2 cases (10%) reached NYHA classification Ⅱ, which were significantly improved compared with those before surgery (all patients' NYHA classification were Ⅳ before surgery). Conclusion:HeartCon LVAD can effectively improve the life quality of patients with ESHF, which has been proved safe and effective in clinical trials, but its long-term effects and complications need further observation and study.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

Background:Small intestinal bleeding is difficult to diagnose and treat because of its complex etiology and limit to examination method. Aims:To analyze the etiology,diagnosis,treatment and prognosis of small intestinal bleeding. Methods:The clinical data of 118 consecutive patients with small intestinal bleeding admitted from Oct. 2006 to Oct. 2016 at Daping Hospital,the Third Military Medical University were retrospectively analyzed. Results:Melena was the most common manifestation of small intestinal bleeding (41. 5％),followed by dark bloody stool,positive fecal occult blood test,hematochezia,and anemia with unknown cause. The major causes of bleeding were benign or malignant tumors (43. 2％),vascular lesions (28. 0％)and inflammatory lesions (15. 3％). Diagnosis was made by means of capsule endoscopy,colonoscopy,digital subtraction angiography (DSA),barium meal examination,multi-slice CT (MSCT)and CT enterography (CTE). Forty-one patients were treated by surgical operation,7 by selective arterial embolization,2 by endoscopic therapy,56 by conservative therapy,and all these patients achieved hemostasis. One patient died of massive hemorrhage and 11 were discharged with giving up of treatment. Conclusions:The leading cause of small intestinal bleeding is tumor,followed by vascular and inflammatory lesions. Capsule endoscopy is able to make definite diagnosis with high accuracy,and MSCT is the most widely used diagnostic approach. In addition to conventional treatment,surgical operation,interventional and endoscopic therapies also play important roles in treating small intestinal bleeding.
