ABSTRACT
ObjectiveTo compare the nocturnal erectile function between SRPE patients and normal people. MethodsFrom July 1st， 2019 to December 15th， 2022， a clinical comparative study was conducted on 29 SRPE patients （experimental group） and 58 volunteers （control group） who visited our urology department. The Rigiscan System was used to monitor sleep monitoring time， the number of nocturnal erections and the rigidity， duration and circumference growth of the penis when the erection reached 60%～79% and 80%～100%， respectively. The patients and volunteers were asked to make written records when they woke up， and then the total number of awakenings and the number of awakenings when the penis erection reached 60% and 80% were compared between the two groups. ResultsAge was eliminated by matching. There was no statistically significant difference in sleep monitoring time， rigidity， circumference growth and duration of the penis when the erection reached 60%～79% and 80%～100%. between the two groups. In terms of sleep， there was a statistically significant difference in the total number of awakenings between the two groups［3（2 ~ 4）vs 0（0 ~ 0），P<0.01］ .And the same was true for the number of awakenings when the penis erection exceeded 60%～79% ［1（0 ~ 1）vs 0（0 ~ 0），P<0.01］and 80%～100% ［2（1 ~ 3）vs 0（0 ~ 0），P<0.01］. ConclusionRigiscan monitoring showed that there was no difference between SRPE patients and normal male in nocturnal penile erection function. Painful awakening usually occurs when the penis erection reaches 60%～79% or 80%～100%， which reveals that SRPE may be caused by abnormal sensation of nocturnal erections or pain sensitivity in some of these patients.
ABSTRACT
ObjectiveTo investigate the current situation of turnover intention of staffs in Center for Disease Control and Prevention（CDC） in the post-COVID-19 era and analyze the influencing factors of turnover intention， so as to provide policy suggestions and reference basis for maintaining the stability of the team of CDC and promote the development of health industry in China. MethodsA questionnaire survey on 1，508 staffs in Shenzhen Center for Disease Control and Prevention by means of WenJuanXing electronic questionnaire from January to February 2023 was conducted .Logistic stepwise regression analysis were used to analyze the influencing factors of turnover intention. ResultsAmong the 1，508 respondents， 583 （38.66%） had resignation intention. Logistic stepwise regression analysis showed that the scores of work arrangement， salary level ，professional title promotion system， occupational will，worry about job prospects were related to the generation of turnover intention ［OR 95%CI： 0.783（0.643， 0.952）； 0.531（0.452， 0.623）； 0.738（0.614， 0.887）； 0.605（0.520， 0.703）； 0.614（0.529， 0.714）］. In addition， job title， age and education were also related to generation of turnover intention （P <0.05）. ConclusionDisease prevention and control institutions should reduce the turnover intention of staffs in CDC through reasonable work arrangement， improvement of salary， adjustment of professional title promotion system， strengthening of professional cognition and enhancing confidence of personnel in career prospects.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the possible effects of apolipoprotein A1 gene (APOA1) rs670 and rs5069 polymorphisms on plasma lipid profiles in healthy adolescents with different body mass index (BMI).</p><p><b>METHODS</b>Totally 723 adolescents were divided into four groups according to their BMI: group 1[BMI =(17.80 ± 0.75)kg/m2], group 2[BMI = (19.39 ± 0.32) kg/m²], group 3[BMI = (20.68 ± 0.43) kg/m²], and group 4[BMI=(23.40 ± 2.05) kg/m²]. Height, weight, waist circumference, hip circumference, blood pressure, heart rate, plasma lipids, and blood glucose were determined, BMI and waist to hip ratio (W/H ratio) were calculated,and genome DNA was extracted for analyzing the genotypes of the APOA1 rs670 and rs5069 polymorphisms by polymerase chain reaction-restriction fragment length polymorphism.</p><p><b>RESULTS</b>No significant differences in height, weight, BMI, waist circumference, hip circumference, W/H ratio, blood pressure, heart rate, plasma lipids, and blood glucose between APOA1 rs670 or rs5069 genotypes were observed among group 1, group 2, and group 3. In group 4, A carriers of the rs670 polymorphism had significantly higher systolic blood pressure (P=0.017) and blood glucose levels (P=0.009) than the adolescents with the GG genotype. T carriers of the rs5069 polymorphism had significantly higher height (P=0.013), weight (P=0.011), and hip circumference (P=0.026) than the adolescents with the CC genotype.</p><p><b>CONCLUSIONS</b>In healthy adolescents with higher BMI, APOA1 rs670 polymorphism is associated with systolic blood pressure and blood glucose levels. The elevation of systolic blood pressure and blood glucose levels in A carriers of APOA1 rs670 polymorphism may be favorably modulated by weight loss.</p>

<p><b>OBJECTIVE</b>To investigate the effects of a high-carbohydrate diet on the lipid and apolipoprotein ratios in healthy young adults with different genotypes of the polymorphism at -75 site in the promoter region of the gene of apolipoprotein AI (APOA1).</p><p><b>METHODS</b>Fifty-six subjects aged (22.89 +/- 1.80) years were given a wash-out diet for 7 days, followed by a high-carbohydrate diet for 6 days. The wash-out diet contained 15% protein, 31% fat, and 54% carbohydrate. The high-carbohydrate diet contained 15% protein, 15% fat, and 70% carbohydrate. Twelve-hour fasting serum lipids and apolipoproteins B100 and AI were measured on the mornings of the 1st, the 8th, and the 14th days from the beginning of the wash-out diet. The ratios of triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC)/HDL-C, low-density lipoprotein cholesterol (LDL-C)/HDL-C, and apolipoprotein B100 (APOB100)/apolipoprotein AI (APOAI) were calculated. The genome DNA was extracted and the polymorphism of APOA1 -75 G/A was determined by polymerase chain reaction followed by restriction fragment length polymorphism assay.</p><p><b>RESULTS</b>At baseline, the lipid and apolipoprotein ratios showed no significant differences between the GG genotype and the A carriers in males (P > 0.05), whereas the female A carriers had a significantly higher ratio of LDL-C/ HDL-C compared with the female subjects with the GG genotype (P < 0.05). Following the high-carbohydrate diet, significant decreases of TC/HDL-C were found in all the groups, regardless of sex and genotype (P < 0.01). LDL-C/HDL-C experienced significant decreases in both the genotypes in males (P < 0.05), while in females, significant decrease of LDL-C/HDL-C was only observed in A carriers (P < 0.01).</p><p><b>CONCLUSION</b>The A allele of the -75 G/A polymorphism in APOA1 may have specific effects on the LDL-C/HDL-C ratio in females.</p>
