Effect of recombinant human brain natriuretic peptide on efficacy, hemodynamics and NT-proBNP in elderly patients with heart failure.

AIM: To investigate the effects of recombinant human brain natriuretic peptide (rhBNP) on efficacy, hemodynamics, and N-terminal pro-brain natriuretic peptide (NT-proBNP) in elderly patients with heart failure (HF). METHODS: In this retrospective analysis, the clinical data of 112 HF patients who visited the First Affiliated Hospital of Anhui University of Chinese Medicine between March 2019 and October 2022 were analyzed. On the basis of standard HF treatment, 52 patients additionally treated with milrinone intravenous were set as the control group (Con) and 60 patients with rhBNP were set as the observation group (Obs). The therapeutic efficacy and pre- and post-treatment echocardiographic indexes, NT-proBNP and hemodynamics were recorded and compared, and the adverse drug reactions and quality of life scores after treatment were counted. RESULTS: The Obs group showed a markedly higher post-treatment overall response rate than the Con (P=0.002). Besides, more obvious improvement of NT-proBNP and hemodynamic indexes were determined in the Obs group compared to the Con (P=0.000). Evidently ameliorated left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD) and left ventricular end-systolic diameter (LVESD) were observed in both groups after treatment, with more pronounced improvement in the Obs group (all P=0.000). The Obs group also exhibited an evidently lower incidence of adverse reactions and a better quality of life than the Con after treatment (P=0.000). CONCLUSIONS: rhBNP can effectively improve the cardiac function and hemodynamics in elderly HF patients, with high safety and few adverse reactions.

Staphylococcal enterotoxin C as a novel strategy for treating lumbar spondylolysis in adolescents: Description of technique.

Lumbar spondylolysis is one of the most common causes of low back pain and primarily affects children and adolescents. Traditional posterior lumbar fixation and interbody fusion surgery has always been the most effective method to treat spondylolysis. However, traditional surgical management has limitations of large trauma, complex operation, high cost, postoperative biomechanical deterioration, and resulting complications. In order to avoid the trauma and complications of surgical treatment, and reduce the cost of treatment. Based on the successful clinical experience of using staphylococcal enterotoxin C (SEC) to treat nonunion after a limb fracture, we identified a minimally invasive method to effectively treat lumbar spondylolysis. A novel minimally invasive therapeutic approach is presented herein of an SEC injection guided by C-arm fluoroscopy to treat lumbar spondylolysis. We describe a novel technique applied in a patient with lumbar spondylolysis, who showed significantly improved low back pain symptoms and a computed tomography scan, including osseous fusion of the bilateral isthmus at L4 after SEC therapy. This is the first reported case description of using an SEC injection to treat lumbar spondylolysis with a successful clinical outcome.

[Correlation between cold pain of knee joint and subchondral bone marrow edema in patients with knee osteoarthritis].

OBJECTIVE: To investigate relationship between cold pain of knee joint and subchondral bone marrow edema (BME). METHODS: From May 2018 to August 2019, 92 patients with knee osteoarthritis (KOA) associated with cold pain of knee were admitted, all patients were underwent MRI examination. The patients were divided into observation group (47 patients with BME) and control group(45 patients without BME). In observation group, there were 6 males and 41 females aged from 36 to 87 years old with an average of (63.2±12.3) years old. In control group, there were 10 males and 35 females, aged from 48 to 84 years old with an average of (62.7±8.3) years old. All patientswere treated with drugs. The degree of joint degeneration was evaluated by Kellgren-Lawrence (K-L) grading. Degree of cold pain of knee was evaluated by knee cold pain score, and degree of BME was evaluated according to WORMS. The correlation between cold pain of knee and K-L grading and BME was analyzed. RESULTS: Score of cold pain in observation group (15.55±7.68) was higher than that of control group (9.42± 5.50), which had significant difference (t=4.383, P<0.001). There was no correlation between cold pain of knee and K-L grading(χ2=2.138, P=0.907). There was correlation between BME grading and degree of cold pain in observation group(χ2=19.709, P<0.001), and Spearman correlation coefficient was rs=0.509(P<0.001). CONCLUSION: The cold pain of KOA patients is not related to K-L grading, but corelate with BME grading. The Cold pain of knee was more pronounced in KOA patients with BME, and the severity of BME is often related to degree of cold pain. It seemed to be a tendency:the more serious BME, the heavier coldpain.

Clinical outcomes of revision with retrograde intermedullary nailing for failed plating of distal femoral fractures: a retrospective study.

PURPOSE: To assess the feasibility and effectiveness of retrograde intramedullary nail (RIN) revision surgeries for locking compression plate (LCP) failure in distal femoral fractures. METHODS: This retrospective study included 13 patients who suffered from metalwork failures after they initially underwent open reduction and LCP fixation. In patients who eventually underwent RIN revision from January 2014 to December 2016, range of motion (ROM) and Hospital for Special Surgery (HSS) scores obtained before surgery and at the final follow-up time were analysed. RESULTS: The average operative time was 155 minutes (range, 120-210 minutes), and the average blood loss volume was 650 ml (range, 200-1350 ml). There were two cases of complications (15.38%): one was calf muscle vein thrombosis, and the other was a superficial infection. No deep tissue infection or deep vein thrombosis was observed post-operatively. The average follow-up time was 16 months (range, 12-24 months). All fractures healed in a mean of 6.5 months (range, 4-12 months), and one patient underwent an additional bone graft surgery that did not involve a bone graft during the RIN revision operation (this eventually healed at 12 months post-operatively). The mean ROM before the operation was 86.92 ± 12.34°. At the final follow-up, the mean ROM was 112.69 ± 9.27°. There was a significant difference between pre-operative and post-operative ROM (P < 0.01). The mean HSS score improved significantly from 38.85 ± 9.62 points pre-operatively to 79.62 ± 5.42 points post-operatively. There was a significant difference between pre-operative and post-operative HSS scores (P < 0.01). CONCLUSIONS: RIN revision surgery achieved excellent clinical results in patients with LCP failure.

[Effect of yanggan yishui granule on collagen I, III, and IV, and FN in spontaneously hypertensive rats].

OBJECTIVE: To observe the effect of Yanggan Yishui Granule (YGYSG) on collagen protein I, III, and IV, as well as fibronection (EN) in spontaneously hypertensive rats (SHR), and to explore its possible renal protective mechanisms. METHODS: Fourty SHR were randomly divided into four groups, i.e., the model group, the Benazepril group, the low dose YGYSG group, and the high dose YGYSG group, 10 in each group. A normal control group was set up with recruited Wistar-Kyoto (WKY) rats. After 6 weeks of treatment, the expression of collagen protein I, III, and IV, as well as FN in the 5.1 image analysis system. RESULTS: In the WKY-control group, there was only a small amount of brown particles in the mesenchymal region, the glomerular basement membrane, or the mesangial region. The expression of collagen I, Ill, and IV, as well as EN significantly increased more in the model group than in the normal control group (P < 0.01). After treatment, the expression of collagen I, III, and IV, as well as FN significantly decreased in each treated group, showing statistical difference when compared with the model group (P < 0.01). Besides, decresed expression of collagen I, III, and IV was shown in the low dose YGYSG group and the Benazepril group (P > 0.05). The expression of collagen I, III, and IV could be further reduced in the high dose YGYSG group, showing statistical difference when compared with the Benazepril group and the low dose YGYSG group (P < 0.05, P < 0.01). CONCLUSION: YGYSG might play an important role in the renal protective effect through reducing the synthesis of renal collagen I, III, and IV, as well as FN, increasing the degradation of renal collagen I, III, and IV, as well as FN, thereby reducing excessive deposition of renal extracellular matrix (ECM).
