Objective:To systematically evaluate the correlation between C-reactive protein (CRP) and postmenopausal osteoporosis.Methods:PubMed, EMbase, Cochrane library, China biomedical literature database, China HowNet and Wanfang database were searched by computer to collect the clinical research literature related to CRP and postmenopausal osteoporosis. The retrieval period was from the establishment of the database to April 1, 2021. The two researchers screened the literature according to the inclusion and exclusion criteria, extracted the data and evaluated the quality, Revman5.3 software was used for meta-analysis.Results:A total of 12 studies were included, including 778 cases in postmenopausal osteoporosis group and 933 cases in non osteoporosis group. The results of combined analysis showed that the level of CRP in postmenopausal osteoporosis group was higher than that in non osteoporosis group, and the difference was statistically significant (standardized mean difference (SMD)=0.55, 95% CI (0.03, 1.07), P=0.04). Further subgroup analysis according to different grouping criteria and CRP detection methods showed that the level of CRP in patients with osteoporosis was higher than that in normal bone group ( SMD=0.88, 95% CI (0.07,1.69), P=0.03). There was no significant difference in CRP level between osteoporosis group and osteopenia Group (SMD=0.13, 95% CI (-0.05, 0.31), P=0.15). There was no correlation between CRP levels detected by automatic analyzer, chemiluminescence immunoassay and enzyme-linked immunosorbent assay and postmenopausal osteoporosis. The level of CRP in postmenopausal osteoporosis group detected by immunoturbidimetry was higher than that in non osteoporosis group (SMD=1.50, 95% CI (1.10,1.90), P<0.01). Conclusion:CRP level is related to postmenopausal osteoporosis. High CRP level may be a risk factor for postmenopausal osteoporosis.

Objective To evaluate the clinical efficacy and safety of anatomical repair and anatomical reconstruction through Meta-analysis.Methods Systematically search PubMed,Embase,Wanfang database,China National Knowledge Infrastructure and other databases were used to obtain the relevant literature in the treatment of chronic lateral instability of the ankle joint with anatomical repair and reconstruction from the establishment of each database to December 2022,and Revman 5.4 and R 4.2 software were used for Meta-analysis.Results Eight articles were finally included in this paper.All were randomized controlled trials.The results of Meta-analysis showed that:there were statistically significant differences between anatomical repair and anatomical reconstruction in the anterior talar translation (MD=0.54,95％CI:0.27-0.81,P<0.01),talus tilt angle (MD=0.36,95％CI:0.07-0.66,P=0.02),and American Orthopaedic Foot & Ankle Society scale (MD=-4.79,95％CI:-6.58--3.01,P<0.01),but there was no statistically significant difference in complications (RR=1.13,95％CI:0.32-3.97,P=0.85).Conclusion Anatomical reconstruction is superior to anatomical repair in clinical efficacy,while the risk of complications is comparable between two.
