Objective:To provide references for effective intervention of hyperuricemia (HUA) by investigating the prevalence of HUA in military pilots and analyzing its relevant influencing factors.Methods:The physical examination data of 2 700 military pilots who received physical examinations from January 2021 to October 2023 were retrospectively analyzed. The above pilots were divided into HUA group and non-HUA group according to whether they had HUA. The differences in age, height, weight, body mass index, flying hours, blood pressure, blood uric acid, fasting blood glucose, total bilirubin, albumin, blood urea nitrogen, blood creatinine, alanine aminotransferase, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol levels, as well as the prevalence of hypertension, hyperlipidemia, and fatty liver were compared between 2 groups. The pilots were grouped by age (≤29 years, 30-39 years, 40-49 years,≥50 years) and by the aircraft types (fighter, bombers, transporter, helicopter). The criteria for determining HUA, hypertension, hyperlipidemia, and fatty liver were based on the relevant guidelines. The influencing factors for the prevalence of HUA were analyzed through binary Logistic regression. Single factor binary Logistic regression was used to analyze the influencing factors of the prevalence of HUA in pilots, and P<0.05 index was included in multi-factor binary Logistic regression to further analyze the influencing factors of the occurrence of HUA. Results:There were 821 cases (30.41%) in HUA group and 1 879 cases (69.59%) in non-HUA group. The weight ( t=7.75, P<0.001), body mass index ( t=8.23, P<0.001), systolic blood pressure ( t=3.20, P=0.001), diastolic blood pressure ( t=3.06, P=0.002), serum uric acid ( t=62.83, P<0.001), blood urea nitrogen ( t=3.41, P=0.001), serum creatinine ( t=8.88, P<0.001), alanine aminotransferase ( t=5.56, P<0.001), total cholesterol ( t=3.27, P=0.001), triglyceride ( Z=9.54, P<0.001), as well as the prevalence of hypertension ( χ2=7.48, P=0.006), hyperlipidemia ( χ2=42.74, P<0.001), and fatty liver ( χ2=22.51, P<0.001) in HUA group were higher than those in non-HUA group, while high-density lipoprotein cholesterol was lower than that in the non-HUA group, and the difference was significant ( t=5.91, P<0.001). There was no significant difference in the prevalence of HUA among pilots of different age groups and aircraft types (both P>0.05). Overweight ( OR=1.392, 95% CI: 1.159-1.672), obesity ( OR=1.891, 95% CI: 1.197-2.987), and elevated level of triglyceride ( OR=1.246, 95% CI:1.128-1.377), blood urea nitrogen ( OR=1.079, 95% CI:1.000-1.163), and serum creatinine ( OR=1.036, 95% CI:1.028-1.044) were risk factors for HUA, and elevated high density lipoprotein cholesterol ( OR=0.567, 95% CI: 0.389-0.825) was a protective factor. Conclusions:The prevalence of HUA in military pilots is higher than that in the general population. Overweight, obesity, and elevated level of triglyceride, blood urea nitrogen, and serum creatinine are closely related to the prevalence of HUA, and comprehensive intervention measures should be taken for key targets.

Objective To summarize the treatment experience and strategies of patients with acute type A aortic dissection involving coronary arteries in order to improve the efficacy of such patients.Methods Between March 2013 and April 2016,we recruited 37 patients with coronary involvement caused by acute type A aortic dissection,26 men,11 women;mean age (49.7 ± 10.4) years.All procedures were done on an emergency basis within 24 hours after the patient's arrival.Results Acute type A aortic dissection with coronary involvement is a more complex operation associated with high in-hospital mortality(18.9％,7/37) and low short-term survival(64.9％,13/37).There were 9 patients underwent coronary artery bypass graft after completion of the root procedure because of ventricular wall motion abnormality(7 patients) and new ST-segment elevation (2 patients) during weaning from cardiopulmonary bypass.Four of them were survival during follow-up due to the success from rescue coronary artery bypass graft.Conclusion Acute type A aortic dissection with coronary involvement is associated with high in-hospital mortality and low short-term survival.If patients suffered abnormal ventricular wall motion or new ST-segment elevation during weaning from cardiopulmonary bypass,rescue coronary artery bypass graft is essential to salvage these critically ill patients.

Objective To compare the changes of some blood indices after treatment of intertro-chanteric fractures with conventional and minimally invasive dynamic hip scres (DHS) internal fixation so as to understand the influence of minimally invasive technique on physiology of the organism. Meth-ods The elderly patients with intertrochanteric fractures in our department from July 2004 to May 2006 were divided randomly into two groups, ie, conventional DHS internal fixation group(Conventional group, 52 patients)and the minimally invasive DHS internal fixation group(Minimal invasion group, 54 patients). A comparison was done on data including white blood cells (WBC), hemoglobin (Hb), e-rythrocyte sedimentation rate (ESR). C reactive protein (CRP) and creatine kinase (CK) as well as re-cessive blood loss. Results The indices including transfusion, blood loss, recessive blood loss, ESR and CK in minimal invasion group showed less changes compared with conventional group. With statistical difference. But WBC and CRP showed no statisfical difference between both groups. Conclusion Minimally invasive DHS internal fvtation carl reduce operative trauma during treatment of intertrochanterie fractures in the elderly.
