Background: To investigate whether the mechanism underlying the anti-inflammatory effects of electroacupuncture (EA) at ST36 involves dopamine (DA) and its receptor and whether it is mediated by the vagus nerve in a rat model of intestinal ischaemia-reperfusion (I/R) injury. Methods: Rats were subjected to gut ischaemia for 30 min and then received EA for 30 min with or without abdominal vagotomy or intraperitoneal administration of butaclamol (D1 receptor antagonist) or spiperone (D2 receptor antagonist). Plasma levels of DA and tumour necrosis factor (TNF)-α were assessed 1 or 4 h after reperfusion. Myeloperoxidase (MPO) activity and malondialdehyde (MDA) content in intestinal tissues were assessed using enzyme-linked immunosorbent assay (ELISA) kits. Intestinal tissue injury was assessed by observation of the pathological lesions and permeability to 4 kDa fluorescein isothiocyanate (FITC)-dextran. Results: EA significantly increased levels of DA and lowered levels of TNF-α. EA also inhibited intestinal levels of MPO and MDA and intestinal tissue injury and decreased intestinal permeability to FITC-dextran. Abdominal vagotomy and intraperitoneal administration of butaclamol (but not spiperone) inhibited the effects of EA. Conclusion: These findings suggest that EA at ST36 could attenuate intestinal I/R-induced inflammatory injury and that the underlying mechanism may involve EA-induced increases in levels of DA, mediated by the vagus nerve and D1 receptors.

Objective To determine cement distribution patterns on therapeutic efficacy after percutaneous vertebroplasty treatment of osteoporotic vertebral compression fractures (OVCFs) with intravertebral cleft (IVC). Methods Patients who were treated with percutaneous vertebroplasty for single OVCFs with IVC and met this study's inclusion criteria were retrospectively reviewed. The follow-up period was at least 2 years. Distribution patterns of cement in the IVC area were respectively specified into 2 groups: group 1: solid lump distribution pattern (n = 22); group 2: the comparatively diffused pattern (n = 90). Radiologic and clinical parameters were analyzed and compared. Then, associations of recollapse with covariates and a risk score were further analyzed and developed to predict recollapse of the augmented vertebrae. Results At the immediate postoperative period, all patients benefited from significant improvement in vertebrae height and kyphotic angle correction. However, significant recollapse was observed at the 2 years postoperative follow-up for the patients in group 1. Furthermore, we found that preoperative severe kyphotic deformity (a cutoff value of 12.5°), solid lump cement distribution pattern, and larger reduction angle (a cutoff value of 8.3°) was significantly associated with increased risk for recollapse. A risk score was developed based on the number of risk factors present in each patient and the receiver operating characteristic curve of the risk score generated an area under the curve of 0.788 (95% confidence interval 0.702–0.873, P = 0.000). Conclusions The comparatively diffused pattern shows better long-term radiologic and clinical outcomes for the treatment for OVCFs with IVC. A risk score can be used to predict the incidence of recollapse. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Recompression of augmented vertebrae (RCAV) is often seen after percutaneous kyphoplasty (PKP), especially at the thoracolumbar junction. The authors aimed to develop and validate a risk prediction model (nomogram) for RCAV and to evaluate the efficacy of a modified puncture technique for RCAV prevention after PKP for thoracolumbar osteoporotic vertebral fractures (OVFs)., Methods: Patients who underwent PKP for single thoracolumbar OVFs (T10-L2) between January 2016 and October 2020 were reviewed and followed up for at least 2 years. All patients were randomly divided into a training group (70%) and a validation group (30%). Relevant potential data affecting recompression were collected. Predictors were screened by using binary logistic regression analysis to construct the nomogram. Calibration and receiver operating characteristic curves were used to evaluate the consistency of the prediction models. Finally, the efficacy of the modified puncture technique for prevention of RCAV in OVF patients with a preoperative intravertebral cleft (IVC) was further demonstrated through binary logistic regression analysis., Results: Overall, 394 patients were included and 116 of them (29.4%) sustained RCAV. The independent risk factors included decreased bone mineral density, lower level of serum 25-hydroxy vitamin D3, larger C7-S1 sagittal vertical axis (SVA), preoperative IVC, and solid-lump cement distribution. The area under the curve (AUC) of the prediction model was 0.824 in the training group and 0.875 in the validation group patients. The calibration curve indicated the predictive power of this nomogram, with the preoperative IVC having the highest prediction accuracy (AUC 0.705). The modified puncture technique significantly reduced the incidence of RCAV by enhancing bone cement distribution into a sufficiently diffused distribution in OVF patients with preoperative IVC., Conclusions: The nomogram prediction model had satisfactory accuracy and clinical utility for identification of patients at low and high risk of postoperative RCAV. Patients at high risk of postoperative RCAV might benefit from the target puncture technique and vitamin D supplementation as well as effective antiosteoporotic therapies.
