ABSTRACT
Objective@#To investigate the current status of HIV-related stigma among college students in Guilin,and to explore the impact of perspective-taking and empathy on HIV-related stigma among college students.@*Methods@#The stratified cluster sampling method was used to select college students from 4 universities in Guilin city. Stratified randomization was used to assign all subjects into a control group (410) and an experimental group (396) for randomized controlled trials,and the HIV-related Stigma Questionnaire and the Basic Empathy Scale were used before and after the intervention.@*Results@#Before the intervention of perspective-taking,there were no statistically significant differences between two groups in subscale scores and total scores of HIV-related stigma (t=0.80，0.35，-0.62，-0.10，P>0.05); However, signiticant differences in subscale scores and total score in HIV-related stigma were found after intervention (t=3.53，2.21，2.30，3.98，P<0.05). There was no statistically singnificant in the scores of all dimensions of empathy level and the total score before the intervention (t=0.10,-0.27,-0.08,P>0.05), dimensional score and total score in empathy were statistically significant after intervention (t=-2.15，-3.06，P<0.05). Empathy played an intermediary role of 14.08% between opinion selection and HIV stigma.@*Conclusion@#HIV-related stigma exists among college students in Guilin,and perspective-taking intervention effectively reduces its AIDS stigma. Empathy plays an intermediary role between them.
ABSTRACT
Objective:To analyze risk factors that were associated with loss of correction curvature after short-segment restoration and fixation in cases who had single-segment thoracolumbar fracture.Methods:87 Cases who had experienced single-segment thoracolumbar fracture and had underwent short-segment restoration and fixation in our department from Jan 2008 to Jan 2011,and had complete follow-up imaging were included.Cobb angles were measured on lateral thoracolumbar X-ray preoperatively,postoperatively and before removal of internal fixation.And these included the angle formed by vertebras that located above and below injured vertebrae (α angle),superior endplate of injured vertebrae and its superior vertebrae (β angle),inferior endplate of injured vertebrae and its inferior vertebrae (γ angle),inferior and superior endplate of injured vertebrae (δ angle).T-test was used to analyze these angles and their changes.And correlation analysis was used to analyze relationships between α angle change and other risk factors.Results:When compared with preoperative angles,the mean α angle,β angle,γ angle and δ angle were all significantly increased (p＜0.05) after the operation.The mean α angle and δ angle before the removal of internal fixation were both significantly smaller than those after the operation (p＜0.05),and the mean change ofα angle was-2.85 degrees.After the correlation analysis,we found significant correlations between the change ofα angle and postoperative correction curvature(-0.342,p=0.026),injured region in endplate(0.374,p=0.015),and change of the δ angle(0.231,p=0.041).Conclusion:There was significant loss in the correction curvature before the removal of internal fixation.And the loss was significantly associated with postoperative correction curvature,injured region in endplate,and change of the δ angle.
ABSTRACT
Acute traumatic central cord syndrome ( ATCCS) is the most common incomplete cervical spinal cord injury .Its di-agnosis mainly depends on the mechanism of injury , physical signs and imaging examination .The main treatment method is conserva-tion or surgery.Here we reviews the progress of its pathogenesis , pathophysiological changes , and surgical treatment advances .
ABSTRACT
BACKGROUND: The number of patients undergoing total knee replacement due to severe gouty arthritis is increasing rapidly in recent years, and the ages of patients also present younger and younger. However, its clinical efficacy remains controversial, and it is lack of retrospective systematic analysis. OBJECTIVE: To assess the clinical efficacy of total knee replacement for severe gouty knee arthritis from several aspects, such as pain, function, quality of life and complications. METHODS: From January 2006 to January 2015, 17 patients (20 knees) with severe knee gouty arthritis received total knee replacement in Department of Orthopedics of Nanjing General Hospital of Nanjing Military Region of Chinese PLA. They underwent knee joint surface replacement with posterior cruciate ligament, and patel a was not replaced. Posterior stabilized prosthesis was used. Al patients were successful y fol owed up postoperatively. The Hospital for SpecialSurgery Knee Score, range of motion of the knee, Visual Analogue Scale score and SF-36 scale scores were determined before and after replacement and during final fol ow-up. RESULTS AND CONCLUSION: Patients were fol owed up for 1-9 years. No serious complications occurred during and after replacement. The Hospital for Special Surgery Knee Score, range of motion of the knee, Visual Analogue Scale score and SF-36 scale scores were significantly higher after replacement and during final fol ow-up than those before replacement (P < 0.001). X-ray films showed good prosthesis position, satisfactory limb alignment without radiolucent lines or loosing. These findings verified that total knee replacement was considered as the final way to treat the severe gouty knee arthritis; its short-term clinical effect is significant, but systematic anti-uric acid, prevention and treatment of complications, pain control, function exercising, and healthy mood maintenance were needed to get a better long-term clinical efficacy.
ABSTRACT
BACKGROUND:Infection is the catastrophic complication after total hip arthroplasty, moreover, its diagnostic criteria has not been unified, and treatment options were also controversial. The removal of the focus of infection was complete or not determines whether the joint could be reconstructed and the joint function could be restored. OBJECTIVE:To analyze the experience and efficacy of thorough debridement in two-stage revision surgery for treatment of infection after hip arthroplasty. METHODS:Total y 23 (24 hips) patients with infection after hip arthroplasty were treated at the Department of Orthopedics, Nanjing General Hospital of Nanjing Military Area Command of PLA from August 2008 to January 2013. The diagnostic criteria were in line with consensus. The repair options defined as two phrases:the first phrase was thorough debridement plus antibiotic-containing bone cement implanted with intervals;the second phrase was joint reconstruction. If the infection persisted in interval, debridement could be repeated, and then underwent joint reconstruction after the thorough control of infection. Harris scores of hip function were determined after revision during fol ow-up. Infection control condition was evaluated. RESULTS AND CONCLUSION:Al the patients were fol owed up, ranged from 1 to 5 years. The Harris scores increased from an average of 36.5 (27-45 scores) before treatment to an average of 88.6 (76-98 scores) after treatment. There was no infection recurrence. Infection control rates reached to 100%. These results suggest that two-stage revision is an effective method for treatment of infection after total hip arthroplasty. Thorough debridement plays a crucial role, and it can effectively control infection recurrence, improve prosthesis stability, so as to reconstruct joint function.
