RESUMO
Objective:To analyze the health screening results for adult men from high altitude areas in a Chengdu health screening center at high altitudes.Methods:The medical and physical examination results of 1 333 plateau people in Sichuan province people′s hospital health physical examination data management center who participated from 2014—2019 and aged 18-80 years old were analyzed. The general data of different age groups were compared using ANOVA analysis. The two groups were compared by independent sample t-test and Mann-Whitney U test, and χ 2 test was used to compare physical examination abnormalities among different age groups. Results:This population was generally overweight and obese, compared to the control group, with systolic blood pressure [(125.29±14.97) vs (123.52±14.87) mmHg(1 mmHg=0.133 kPa), height (168.64±6.26) vs (169.31±6.26) cm, weight (79.47±13.69) vs (71.02±10.62) kg, body mass index (27.91±4.45) vs (24.75±3.24) kg/m2, haemoglobin (169.03±15.18) vs (157.50±11.52) g/L, uric acid (393.12±75.48) vs (410.42±82.14) μmol/L, triacylglycerols 1.18(0.90, 1.69) vs 1.64(1.12, 2.37) mmol/L, total cholesterol 4.58(4.02, 5.15) vs 4.82(4.33, 5.36) mmol/L, HDL cholesterol 1.28(1.14, 1.46) vs 1.26(1.08, 1.46) mmol/L, LDL cholesterol 2.91(2.41, 3.42) vs 3.03(2.49, 3.60) mmol/L] levels were statistically significant (all P<0.05). The physical examination abnormalities detected were fatty liver, hyperlipidemia, abnormal liver function, hyperuricemia, elevated blood glucose, elevated blood pressure, gallbladder disease, abnormal kidney function, prostate hyperplasia, and erythrocytosis. The differences in the detection rates of the above abnormalities were statistically significant when compared between different age groups. Conclusion:The health status of the adult population from high altitude areas screened in our center is critical; therefore, appropriate health interventions need to be made.
RESUMO
Objective To study mechanical properties of the novel micro-movement elastic implant of distal tibiofibular syndesmosis in dorsiflexion position.Methods A combination of simulation and experiment was used. The normal ankle dorsiflexion model, the bone nail repaired model and the micro-movement elastic implant repaired model were established by using Mimics and CT data. Besides, ANSYS Workbench was used for finite element analysis. Mechanical experiments on lower limb specimens were conducted on Instron E10000 mechanical test instrument, and five sets of experimental data were measured and analyzed.Results Mechanical properties of the micro-movement elastic implant repaired model were closer to those of the normal ankle dorsiflexion model, but stress of the micro-movement elastic implant repaired mode was greater than that of the bone nail repaired model. The results of two-sample heteroscedasticity t test indicated that there was no significant difference in resistance torque between the micro-movement elastic implant repaired model and the normal ankle dorsiflexion model.Conclusions For dorsiflexion position, repairing mechanical properties of the novel micro-movement elastic implant are much better than those of the bone nail, and there is still room for optimizing the micro-movement elastic implant.
