目的 研究高尿酸（UA）和肥胖的交互作用对非酒精性脂肪肝病（NAFLD）患病率的影响。方法 采用病例对照的研究法,选取2021年1月至2021年12月兰州市某医院健康体检中心进行常规健康体检的504人为研究对象,按照诊断标准分为NAFLD组187人和非NAFLD 组317人。采用Logistic 回归模型、相乘、相加交互模型探讨非酒精性脂肪肝病患病风险的影响因素及因素间的交互作用。结果 多因素条件Logistic回归分析可知,肥胖（OR=4.87,95%CI：3.01~7.89）,糖尿病患者（OR=3.40,95%CI：1.51~7.68）,幽门螺杆菌（Hp）携带者（OR=1.62,95%CI：1.03~2.57）,高尿酸血症的NAFLD患病风险增加,分别是正常者、非糖尿病患者、非Hp携带者,非高尿酸血症的4.87倍,3.40倍,1.62倍,2.28倍,在调整混杂因素后交互作用结果显示,高尿酸血症和肥胖对NAFLD患病率有相乘交互作用（OR=0.30,95%CI：0.10~0.88,P=0.029）、但无相加交互作用（相对超额危险度比=3.15、归因比=0.24、协同指数=1.34）。结论 BMI、糖尿病、Hp是NAFLD患病的独立危险因素,其中高尿酸血症和超重与肥胖对NAFLD患病有相乘交互作用,无相加交互作用。

Objective To explore the influence of the interaction of high uric acid（UA）and obesity on the prevalence of non-alcoholic fatty liver disease（NAFLD）．Methods Using a case-control study method,504 people who underwent routine health checkups at the health checkup centre of a hospital in Lanzhou City from January 2021 to December 2021 were enrolled in the study,and 187 people were included in the NAFLD group and 317 people in the non-NAFLD group according to the diagnostic criteria．Logistic regression models,multiplicative and additive interaction models were used to investigate the factors affecting the risk factors of NAFLD and the interaction between the factors．Results Multifactorial conditional logistic regression analysis showed that the risk of NAFLD was increased in obese（OR=4.87,95% CI：3.01-7.89）,diabetic patients（OR=3.40,95% CI：1.51-7.68）,Helicobacter pylori（Hp）carriers（OR=1.62,95% CI：1.03-2.57）;the increased risk of NAFLD prevalence in hyperuricaemia patients was 4.87,3.40,1.62,and 2.28 times higher than that of normal,non-diabetic,non-Hp carriers,and non-hyperuricemic individuals,respectively．And the adjusted interaction showed a multiplicative interaction of hyperuricaemia and obesity on the prevalence of NAFLD after controlling for the confounders（OR=0.30,95% CI：0.10-0.88,P=0.029）,but no additive interaction （relative excess risk due to interaction=3.15,attributable proportion due to interaction=0.24,and synergy index=1.34） interactions．Conclusions BMI,diabetes mellitus,and Hp were independent risk factors for the prevalence of NAFLD,with hyperuricaemia and overweight and obesity having multiplicative interaction and no additive interaction．

目的 通过对不同职业人群前列腺疾病患病情况及相关危险因素进行分析,探讨不同职业人群前列腺疾病的患病率及相关危险因素。方法 选择2019年1月—2019年12月在我院健康管理中心进行前列腺超声检查的不同职业人群3 219例,按其职业分为5类:医务人员、国企职工、私企职工、高校教职工和银行职工,分析不同职业人群前列腺疾病患病情况及其相关影响因素。结果 3 219例受检者中,前列腺疾病的患病率为43.96%,前列腺疾病患病率随着年龄的增长而升高(P＜0.001);20～29岁及30～39岁年龄组前列腺钙化患病率均高于其他三种类型前列腺疾病(P＜0.001),而60岁以上年龄组前列腺增生和合并两种及以上前列腺疾病患病率均高于其他两种类型前列腺疾病(P＜0.001);前列腺增生和合并两种及以上前列腺疾病的患病率均随着年龄的增长而递增(P＜0.001);不同职业人群前列腺疾病的患病率不同(P＜0.001),银行职工的前列腺疾病患病率最高,为52.36%;体质量指数升高组、血压升高组和血脂升高组的前列腺钙化患病率均高于其对应的正常组(P＜0.05);体质量指数升高组、血糖升高组、血压升高组和血脂升高组的前列腺增生患病率均高于其对应的正常组(P＜0.001)。结论 不同的职业群体前列腺疾病的患病情况不一样,体质量指数升高、血压升高、血脂升高及血糖升高等相关因素增加患前列腺疾病的风险,应加强前列腺疾病预防保健方面的健康宣传,提倡健康的生活方式,从而降低前列腺疾病的患病率。

Objective To study on epidemic situation of prostate disease and related risk factors in different occupational groups by analyzing the prevalence and related risk factors of prostate disease in different occupational groups. Methods 3 219 cases of five different occupations including medical staffs, state-owned enterprise staffs, private enterprise staffs,college staffs and bank staffs who had underwent prostate ultrasonography in the health management centre department of the Fifth Affiliated Hospital of Guangzhou Medical University from January 2019 to December 2019 were included as study objects to analyze the prevalence of prostate disease and its related factors in different occupational groups. Results The prevalence of prostate disease was 43.96% in 3 219 cases of different occupational groups, and the prevalence of prostate disease increased greatly with age(P＜0.001). The detection rates of prostate calcification in the age group of 20-29 and 30-39 were greatly higher than the other three types of prostate diseases(P＜0.001). The detection rate of BPH and with two or more prostate diseases in the age group over 60 years old was greatly higher than the other two types of prostate diseases(P＜0.001);The detection rates of BPH and with two or more prostate diseases were significantly increased with age (P＜0.001). There was an obvious difference inthe prevalence of prostate diseasesamong different occupational groups(P＜0.001). The prevalence of prostate disease in bank staffs was 52.36%, which was the highest among the five occupations. The prevalence of prostate calcification in the group with high body mass index, high blood pressure and high blood lipid were greatly higher than that of their normal group(P＜0.05). The prevalence of BPH in the group with high body mass index, high blood glucose, high blood pressure and high blood lipid were higher than that of their greatly normal group(P＜0.001). Conclusions The prevalence of prostate diseases is different among different occupational groups. Relative factors such as high body mass index, high blood glucose, high blood pressure and high blood lipid will increase the risk of prostate disease. By strengthening the health promotion of prostate disease prevention and health care, promoting a healthy lifestyle, it may reduce the prevalence of prostate disease.

目的 分析惠州地区高尿酸血症患病率,探讨血清雌二醇水平与高尿酸症之间的相关性。方法 选择惠州市第一人民医院500名体检人员为研究对象,检测血清中尿酸浓度,女性同时检测雌二醇。结果 惠州地区高尿酸血症总患病率为23.2%(116/500),男性及女性分别为27.91%(72/258)和18.18%(44/242)(χ²＝6.628,P=0.010),不同性别血清尿酸浓度差异显著(Z=-15.961,P<0.001)。各年龄段男性血清尿酸水平(χ²=6.432,P=0.169)及患病率(χ²＝3.989,P=0.408)均相近。50岁以上女性患病率与男性无差异(χ²=0.088,P=0.766),20～49岁女性血清尿酸水平(Z=-3.856,P<0.001)及患病率(χ²=9.532,P=0.002)均低于50岁以上女性。20～49岁女性雌二醇高于50岁以上女性(Z＝-6.171,P<0.001),尿酸与雌二醇具有负相关性,r=-0.464。结论 除50岁以上女性外,惠州地区健康人群高尿酸血症患病率与国内多数地区人群相近,女性50岁进入绝经期后高尿酸血症患病率的快速上升与体内雌激素下降呈负相关。

Objective To analyze the prevalence rate of hyperuricemia (HUA) in Huizhou and investigate the relationship between HUA and estradiol(E2). Methods 500 health people from Huizhou first hospital were enrolled. Uric acid and E2 in female was detected. Results The overall prevalence rate of HUA was 23.2%(116/500). The prevalence rate of male and female were 27.91% (72/258)and 18.18%(44/242), respectively(χ²＝6.628,P=0.010). There was no significantly difference between male and female in the level of uric acid(Z=-15.961,P<0.001) The levels ofuricacid in serum(χ²=6.432,P=0.169)and the prevalence rate (χ²＝1.1,P>0.05)were closed to each age bracket in male group. The prevalence rate of male over 50 years old was closed to female(χ²=0.0144,P>0.05).In 20 to 49 years old female group, prevalence rate was lower(χ²=6.084,P<0.025) and uric acid in serum(χ²=17.599,P<0.001)was lower than that of the group over 50 years old. The levels of E2 of female under 50 years old was higher than that above 50 years old(χ²＝41.292,P<0.001).There was negative correlation between uric acid and E2, and the correlation coefficient was -0.464. Conclusion The prevalence rate of HUA in Huizhou is close to most area in China except female over 50 years old. After menopause, the rapid rise of prevalence rate of HUA in female is associated with the descending of E2.
