ABSTRACT
Objective:To evaluate the clinical outcomes of neutral wedge osteotomy assisted by determination of the center of rotation of angulation (CORA) at the distal humerus anatomical axis for cubitus varus deformity in children.Methods:From 2016 to December 2019, 20 children with cubitus varus after supracondylar fracture of the humerus were treated at Department of Orthopeadics, Children's Hospital of Wujiang District. They were 8 boys and 12 girls, aged from 4 to 12 years (average, 7.0 years). Standard anteroposterior X-ray films of bilateral humerus were taken preoperatively for measurement of Baumann angle, proximal anatomical axis (PAA) and distal anatomical axis (DAA) of bilateral humerus to determine the CORA and the varus deformity angle. A lateral closed neutral wedge osteotomy was performed around the CORA to correct the varus deformity. All children were immobilized with elbow plaster cast after operation. Elbow flexion and extension function, postoperative scar, and body surface carrying angle were recorded. The carrying angle and Baumann angle were also measured on elbow X-ray films. Elbow function was evaluated according to the modified Flynn elbow score at 24 months after operation.Results:All patients were followed up for 24 to 36 months (mean, 29.3 months). Elbow hyperextension was close to normal in 18 cases, and 5° hyperextension existed in 2 cases. The flexion was greater than 130°, averaging 133.1° (from 130° to 138°), in 15 patients. The flexion ranged from 110° to 130° in 5 patients. The Baumann angle was 99.0°±1.0° preoperatively and 76.0°±1.0° postoperatively; the carrying angle was -14.0°±1.0° preoperatively and 13.6°±1.0° postoperatively. There were significant differences between the above items between preoperation and postoperation ( P<0.05). According to the modified Flynn elbow score at 24 months after operation, the elbow function was excellent in 16 and good in 4 cases. The varus of 40° was corrected during surgery in one child. Fixation failure or correction failure occurred in none of the children before removal of the plaster or the Kirschner wire. Conclusions:In neutral wedge osteotomy assisted by determination of the CORA at the distal humerus anatomical axis, the CORA and angulation of the distal humerus inversion can be accurately determined so that the osteotomy line and the angulation correction axis can pass through the CORA to restore the humerus alignment with no displacement of the broken ends.
ABSTRACT
ObjectiveTo investigate the correlation of quality of life (QOL) with aspartate aminotransferase-to-platelet ratio index (APRI), liver stiffness measurement (LSM), and histopathology after entecavir antiviral therapy for patients with chronic hepatitis B liver fibrosis. MethodsA total of 95 patients who were diagnosed with chronic hepatitis B and liver fibrosis in The Affiliated Hospital of Yanbian University from October 2013 to March 2015 were enrolled, and all patients underwent entecavir antiviral therapy. Before treatment and at weeks 26, 52, and 78 of treatment, SF-36 scale was used to assess QOL, transient elastography was used to measure LSM, and serum APRI was measured. Among these patients, 31 underwent liver biopsy before treatment and at week 78 of treatment to observe the degree of inflammation and fibrosis, and QOL, APRI, LSM, and histopathology were analyzed before and after antiviral therapy. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data at different time points, and a Spearman correlation analysis was performed. ResultsThere was a tendency of increase in QOL after antiviral treatment, and there were significant differences in general health, role-physical, role-motional, bodily pain, social functioning, and vitality at different time points (H=25.084, 8.699, 12.293, 22.874, 12.079, and 10.403, all P＜0.05). There was a tendency of reduction in APRI, with a significant change after treatment (H=60.030, P＜0.01), and there was also a significant reduction in LSM after treatment (H=35.744, P＜0.01). APRI and LSM were negatively correlated with QOL (all P＜0.05). Among the patients who underwent liver biopsy, 22 achieved the improvement in histological inflammation after antiviral therapy, 15 achieved the improvement in fibrosis, 14 achieved the improvement in both inflammation and QOL, and 8 achieved the improvement in both fibrosis and QOL. ConclusionEntecavir antiviral therapy can improve the QOL of patients with chronic hepatitis B liver fibrosis, and reductions in APRI and LSM can predict the improvement in QOL in patients with chronic hepatitis B liver fibrosis. Improvement in histological inflammation and fibrosis have a certain effect on the improvement in QOL in patients with chronic hepatitis B liver fibrosis.
ABSTRACT
Objective To investigate the incidence of thyroid space occupying lesion by ultrasound imaging in patients with breast cancer.Methods From 2009 to 2012,150 patients with breast cancer as experimental group and another 150 patients with breast benign diseases as control group underwent thyroid ultrasound examination.Ultrasound results of the two groups were analyzed to find the differences.Restult More obvious space occupying lesions were found in experimental group than those in control group (P＜0.05).Conclusion The incidence rate of thyroid space occupying lesion in the patients with breast cancer is higher than that in the patients with no breast cancer.
ABSTRACT
Objective To study the chemical constitients of Polygonum cuspidatum.Methods The compounds were isolated through column chromatography and their structures were elucidated through physicochemical and spectral analyses.Results Seven compounds were obtained from the diethyl ether fraction of ethanol extract and identified as physcion(Ⅰ),emodin(Ⅱ),ambrettolide(Ⅲ),?-sitosterol(Ⅳ),oleanolic acid(Ⅴ),coumarin(Ⅵ),and 2-ethoxy-8-acetyl-1,4-naphthoquinone(Ⅶ).Conclusion Compound Ⅶ is a new compound named as cuspidatumin A,and compound Ⅲ is obtained from P.cuspidatum for the first time.
