Objective To evaluate the clinical value of using three-dimensional reconstruction and incising software in facial fracture. Methods Twenty-nine patients of facial fracture were examined with spiral CT first and then the images were taken with three-dimensional reconstruction and incising software on work-station. 2D images, 3D images and incising images were evaluated. Results BZ 3D images were superior to 2D images in demonstrating the space relationship of facial fractures, such as the fracture location, range, fragments displacement. However 2D images were better in illustrating deep structure; The 3D images could illustrate deep structure as well as 2D images when combined with incising software. Conclusion 3D images can provide information of space relationship in assessing facial fracture. The range can be extended combining with the incising software, and do better for illustrating deep struction.

In the treatment of facial paralysis in the acute stage and restoration stage by shallow needling technique and penetrating needling technique respectively, totally 106 cases, the effective rate is respectively 98.6% and 83.9%, indicating that the curative rate is high if early treatment is given.

Objective To evaluate the guiding effect of CT software to reduce the postoperative syndrome and surgery risk in patients with sinus disease performed the functional endoscopic sinus surgery (FESS). Methods Fifty patients of accessory sinus disease were scanned by spinal CT, and then three dimensions reconstruction made in workstation. Under center of ethmoid sinus ,the five groups of anatomy data measured were obtained , used to guide surgery and contrasted with result of no used to guide surgery in 68 patients in FESS. The data were performed the statistical management and compared with results of FESS. Results Under guided by five groups of anatomy data measured ,the postoperative syndrome was reduced by 16.0 percent; the curative effect went up by 15.0 percent; the pay for hospital was reduced 31.0 percent and the recurrence rate was reduced 8.6 percent. Conclusion Used the technic in FESS, the surgery risk, the recurrence rate and pay for hospital are reduced, but the curative effect go up. The technic is much adapt to be used in village and towns hospital where there aren′t navigation equipment.

BACKGROUND:The surgical method for the treatment of unstable distal radius fracture mainly includes plate internal fixation and external fixator, but both of these two methods have the advantages and disadvantages. Which treatment is more conducive to the rehabilitation of patients, there is stil controversy.
OBJECTIVE:To evaluate the clinical effectiveness of internal fixation and external fixator for the treatment of unstable distal radius fractures.
METHODS:The relative databases and literatures were searched with the computer and hand to col ect the randomized control ed trials of internal fixation versus external fixator for the treatment of unstable distal radius fractures. After extraction literature data and quality evaluation, RevMan 5.2 software was used for system evaluation. The grip strength, disabilities of arm, shoulder&hand score, complications rates, infection rates, deformity rates and ulnar variance rates were compared between two groups.
RESULTS AND CONCLUSION:A total of 9 literatures, involving total y 524 patients were included, 286 patients in the internal fixation group and 238 patients in the external fixator group. There was no significant difference in grip strength between internal fixation group and the external fixator group. The results of Meta-analysis showed that the internal fixation group was better than the external fixator group in the aspects of disabilities of arm, shoulder&hand score, complications rate, infection rate, deformity rate and ulnar variance rate at 3 months and 1 year after treatment. The results indicate that the plate internal fixation is better than external fixator in the treatment of unstable distal radius fractures, but the large sample, double-blind, and high quality randomized control ed trials are stil needed to identify the results.

Objective:To explore the predictive value of systemic immune-inflammation index (SII) and small and dense low-density lipoprotein-cholesterol (sdLDL-C) on contrast-induced acute kidney injury (CI-AKI) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing emergency percutaneous coronary intervention (PCI).Methods:This retrospective analysis included 674 STEMI patients who underwent emergency PCI in Affiliated Hospital of Xuzhou Medical University from November 2019 to October 2021, all patients were divided into a training cohort ( n=450) and validation cohort ( n=224) at a ratio of 2∶1 according to the chronological sequence. The patients in the training cohort were further divided into CI-AKI group ( n=92) and non-CI-AKI group ( n=358). Information at admission and emergency blood biochemical indexes were collected, and the SII was calculated. Multifactorial logistic regression analysis was used to explore the independent factors influencing the occurrence of CI-AKI in STEMI patients undergoing emergency PCI in the training cohort and a predictive model was established. Receiver operating characteristic (ROC) curve and Hosmer-Lemeshow test were used to evaluate the model discrimination and calibration. Results:The prevalence of CI-AKI was 20.4% (92/450). Age, proportion of women, sdLDL-C, urea, baseline creatinine, uric acid, neutrophil count, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and SII were significantly higher in the CI-AKI group than in the non-CI-AKI group (all P<0.05), and left ventricular ejection fraction (LVEF), high-density lipoprotein cholesterol, estimated glomerular filtration rate (eGFR) and lymphocyte count were significantly lower in the CI-AKI group than in the non-CI-AKI group (all P<0.05). The results of multifactorial logistic regression analysis showed that age ( OR=1.046, P=0.001), LVEF ( OR=0.916, P<0.001), sdLDL-C ( OR=4.754, P<0.001), uric acid ( OR=1.012, P=0.007), eGFR ( OR=0.994, P=0.002), and lnSII ( OR=2.471, P<0.001) were independent determinants of CI-AKI after emergency PCI in STEMI patients. ROC curve analysis showed that area under the curve (AUC) for the diagnosis of CI-AKI was 0.688 with a sensitivity of 73.9% and specificity of 61.5% for the SII cut-off point of 1 179.07×10 9/L. The AUC for the diagnosis of CI-AKI was 0.709 with a sensitivity of 65.2% and specificity of 77.4% for the sdLDL-C cut-off point of 1.147 mmol/L. The AUC for the diagnosis of CI-AKI was 0.847 with a sensitivity of 88.0% and a specificity of 70.6% for the combination of SII and sdLDL-C with age, LVEF, uric acid and eGFR. The Hosmer-Lemeshow test (χ2=6.913, P=0.546) proved the goodness of fit of the model. Conclusions:SII and sdLDL-C have significant clinical value in the prediction of CI-AKI. SII and sdLDL-C combined with age, LVEF, uric acid and eGFR could further improve the predictive efficacy of CI-AKI.
