Objective To understand and analyze the status of semen quality in men of different ages in Baiyun District of Guangzhou. Methods From January 2020 to December 2021,married men who received pre-pregnant physical examination in our center were selected as the research subjects．Routine semen testing was conducted,and samples were collected for semen analysis. Results Only 3176 cases（57.52%）of male semen data of childbearing age in Baiyun District were within the normal range．With the increase of age,total semen motility,survival rate and sperm forward motility decreased gradually（P < 0.05）. Conclusions Men in the age group of 26-30 years had higher normal rates of all indicators of semen quality than other age groups（P < 0.05）,which is the golden age of male fertility.

目的 调查儿科急诊非急诊手术患儿输血后红细胞恢复的影响因素。方法 回顾2020年1月—2020年12月期间广州市妇女儿童医疗中心珠江新城院区儿科急诊1月~18岁患儿的输血情况,其中分为Hb提升达预期组（n=93）,Hb提升未达预期组（n=156）,根据年龄、性别、体质量、是否恶性肿瘤、是否发热、有无延迟输血、输血前血红蛋白水平、输注红细胞类型情况,分析输血疗效及影响因素。结果 2组患儿的性别、年龄、体质量、有无恶性肿瘤、是否发热、输血等待时间、输血前后血红蛋白值、输注红细胞悬液量以及有无及时输血均无统计学差异;输注红细胞类型组间存在显著差异,Hb提升未达预期组更多输注了洗涤红细胞悬液（13.5% vs 5.4%,P=0.044）,输血后 Hb 值较低（中位数,73 g/L vs 84 g/L,P<0.001）,变化 Hb 值较小（中位数,18 g/L vs 30 g/L,P<0.001）,归因分析未发现影响因素。结论 输注洗涤红细胞可能是降低输血后红细胞提升的影响因素,输注洗涤红细胞时需严格输血指征同时注意红细胞提高预值的设定。

Objective To investigate the influencing factors of blood transfusion efficacy in patients without emergency operations in pediatric emergency．Methods A retrospective analysis of the blood transfusion of pediatric emergency children（1 month~ 18 year of age）in Zhujiang New Town Branch of Guangzhou Women and Children's Medical Center from January 2020 to December 2020 was carried out,patients were divided into Hb elevation up to expectation group（n=93）and Hb elevation not up to expectation group（n=156）．The efficacy of blood transfusion and the factors affecting it were analyzed according to age,gender,body mass,with or without malignant tumor,whether fever was present,whether there was delayed transfusion,pre-transfusion hemoglobin level,and the type of red blood cells transfused．Results There were no significant differences in gender,age,weight,malignant tumor,fever,waiting time for blood transfusion,hemoglobin level before and after blood transfusion,infusion volume of red blood cell suspension and whether had timely blood transfusion between the two groups．Significant differences were found between groups of transfused red blood cell types,with more washed red blood cell suspensions transfused in the Hb elevation not meeting expectations group（13.5% vs 5.4%,P=0.044）,which had lower post-transfusion Hb values（median,73 g/L vs 84 g/L,P<0.001）,and smaller change Hb values（median,18 g/L vs 30 g/L,P<0.001）,and attribution analysis did not reveal influencing factors．Conclusions Transfusion of washed red blood cell may be an influencing factor that reduces the RBCs elevation after transfusion．Attention should be paid to strict indications for washed red blood cell transfusion and setting the expected Hb level.

Objective To investigate the risk factors of cholesterol polyps formation．Methods The 219 patients who underwent laparoscopic cholecystectomy in Guangzhou First People's Hospital were divided into cholesterol polyps group（162 cases）and non-cholesterol polyp group（57 cases）according to postoperative gallbladder pathological results．The age,gender,blood lipids levels,liver function,high-sensitivity C-reactive protein,CA199,carcinoembryonic antigen（CEA）,history of gallstones,diabetes,and liver cirrhosis of all patients were collected and statistically processed．Results Mann-Whitney U analysis by nonparametric test method showed that the lipid metabolism-related indexes were significantly different between the cholesterol polyps group and the non-cholesterol polyp group．The total cholesterol indexes in the cholesterol polyps group were higher than those in the non-cholesterol polyp group,and higher than the reference range．The cholesterol polyps group and the non-cholesterol polyp group had statistical significance in some lipid metabolism indexes,but they were all in the normal range．Logistic regression analysis of cholesterol polyps formation showed the obtained Logistic model was statistically significant,χ²=179.14,P<0.001．Among the 8 independent variables included in the model,total cholesterol was statistically significant．For each unit increased in total cholesterol,the risk of developing cholesterol polyps increased by 38.2 times compared with the non-cholesterol polyp group．Conclusions Total cholesterol is a high risk factor for the formation of cholesterol gallbladder polyps．
