Validation of fatty liver index and hepatic steatosis index for screening of non-alcoholic fatty liver disease in adults with obstructive sleep apnea hypopnea syndrome / 中华医学杂志(英文版)

Background@#Obstructive sleep apnea hypopnea syndrome (OSAHS) is a contributing factor for non-alcoholic fatty liver disease (NAFLD). Non-invasive algorithms including fatty liver index (FLI) and hepatic steatosis index (HSI) have been used as a screening test for NAFLD in epidemiologic studies. The aim of this study is to compare the diagnostic accuracy of FLI and HSI for NAFLD detection in adults with OSAHS.@*Methods@#We enrolled consecutive adult subjects who were newly diagnosed with OSAHS from March 2016 to January 2018. NAFLD was diagnosed by ultrasonography. The accuracy and cut-off point of the FLI and HSI to detect NAFLD were assessed by analyzing the area under the receiver operating characteristic (AUROC) curve and the maximum Youden index analysis, respectively.@*Results@#The 326 subjects were diagnosed as NAFLD according to ultrasound findings, while 105 subjects who had normal abdominal ultrasonography were grouped as controls. Both FLI and HSI values were significantly higher in patients with NAFLD compared with controls. The AUROC of FLI and HSI for predicting NAFLD was 0.802 (95% confidence interval [CI] 0.762-0.839) and 0.753 (95% CI 0.710-0.793), respectively. The AUROC of FLI was significantly higher than that of HSI (P = 0.0383). The optimal cut-off value of FLI and HSI was 60 (sensitivity 66% and specificity 80%) and 35 (sensitivity 81% and specificity 60%), respectively.@*Conclusions@#Both FLI and HSI can serve as screening tools for NAFLD in OSAHS adults. The FLI shows better performance in diagnosing NAFLD than HSI.@*Trial registration@#Chinese Clinical Trial Registry (No. ChiCTR-OOB-15007253), http://www.chictr.org.cn/showproj.aspx?proj=11606.

Surgical treatment for Lisfranc injuries accompanied by the base crashing of the second metatarsal bone / 中国骨伤

<p><b>OBJECTIVE</b>To discuss the clinical effects of open reduction and internal fixation (ORIF) for treatment of patients with Lisfranc injury combined the second metatarsal base comminuted fracture.</p><p><b>METHODS</b>From March 2007 to June 2012, 7 patients with Lisfranc injury combined the second metatarsal base comminuted fracture were treated including 5 males and 2 female aged from 22 to 51 years old (means 42 years), 4 of sprain and 3 of traffic injury. According Myerson classification, there was 1 case of type A, 3 of type B and 3 of type C. Kirschner wire was used to fix Lisfranc ligament placing from the medial cuneiform bone to the second metatarsal base during the operation. After the operation American Orthopaedic Foot and Ankle Society (AOFAS) criteria system were applied to evaluate the foot and ankle function. Preoperative and postoperative AP, lateral and oblique X-ray and CT scan were collected for radiographic evaluation.</p><p><b>RESULTS</b>All patients were followed up from 12 to 20 months (16.8 months in average). According to AOFAS criteria system, 3 cases were excellent result,3 good, 1 fair. All the wounds were primary healing without skin necrosis, infection, Kirschner loose,broken, or other complications.</p><p><b>CONCLUSION</b>Kirschner wire had good clinical efficacy for fixing Lisfranc ligament injury with the second metatarsal base comminuted fracture, and could avoid arthrodesis.</p>

Expression and significance of MMP3 in synovium of knee joint at different stage in osteoarthritis patients

OBJECTIVE@#To investigate the expression and significance of MMP-3 in synovium of knee joint at different stage in osteoarthritis (OA) patients.@*METHODS@#Knee synovial tissue were collected in 90 OA patients (the OA group). Patients in the OA group was divided into 3 subgroups: grade I subgroup (n=30), grade II subgroup (n=30), grade III; subgroup (n=30). Thirty patients served as control group. Immunohistochemical assay was used to detect the expression of MMP-3 protein in the knee synovial tissue.@*RESULTS@#MMP-3 protein was detected in all knee synovial tissue. The expression of MMP-3 protein in the OA group was significantly higher that in the normal synovium (P<0.05), and the MMP-3 protein was mainly located in the cytoplasm. There was significant difference in the expression of MMP-3 protein between the grade I subgroup and the grade II, grade III subgroups (all P<0.05). The expression of MMP-3 protein was positively related to the severity of OA (r=0.912, P<0.05).@*CONCLUSIONS@#The expression of MMP-3 protein are closely related to pathogenic mechanism of OA. It may be an important indicator of early diagnosis and the activity of the disease of osteoarthritis.
