Objective To explore the change of proportion of peripheral blood dendritic cells (DCs) in patients with stroke. Methods 56 patients (30 cases of cerebral infarction and 26 cases of cerebral hemorrhage) in Beijing Bo'ai hospital from June to September, 2014 and 14 healthy controls were investigated. The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS). Flow cy-tometry analysis was employed to detect the proportion of DCs subtypes in the peripheral blood. Results No obvious difference was found in DCs between the stroke patients and the controls. Compared to the control group, the percentages of peripheral blood myeloid dendritic cells (mDCs) decreased in the cerebral hemorrhage and the cerebral infarction subgroups (P<0.001). The percentages of plasmacytoid den-dritic cells (pDCs) reduced significantly in the cerebral hemorrhage and the cerebral infarction subgroups (P<0.05). The stroke patients were divided into NIHSS≤7 subgroup and NIHSS>7 subgroup. The percentages of pDCs in the cerebral hemorrhage and the cerebral infarction patients were significantly lower in the NIHSS>7 subgroup than in the NIHSS≤7 subgroup (P<0.05). While there was no statistical differ-ence between NIHSS≤7 subgroups and NIHSS>7 subgroups in the percentages of mDCs in the cerebral hemorrhage and cerebral infarction patients. Conclusion The proportion of DCs subtypes in the peripheral blood in stroke patients changed significantly, indicating inflamma-tion responds play a role in stroke.

OBJECTIVETo analyze the serum total cholesterol level and the prevalence of hypercholesterolemia and borderline high cholesterolemia among urban-resident adults in China from 2010 to 2012.

METHODSData were from Chinese Nutrition and Health Surveillance in 2010-2012. Multi-stage stratified proportion to the population cluster random sampling method was conducted to determine 54 042 adult residents in 34 big cities and 41 small and medium-sized cities. Serum total cholesterol was measured by cholesterol oxidase method. Hypercholesterolemia and borderline high cholesterolemia were evaluated by Guidelines on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults 2007 edition. Standardized cholesterol level (x ± Sx) and prevalence of hypercholesterolemia and borderline high cholesterolemia were calculated through weighted complex sampling processing by population data released by the National Bureau of Statistics in 2009.

RESULTSThe mean level of urban-resident adults's erum total cholesterol was (4.58 ± 0.05)mmol/L, (4.58 ± 0.05)mmol/L for both male and female. The cholesterol concentration level in big cities and small and medium-sized cities were (4.66 ± 0.04)mmol/L and (4.57 ± 0.06) mmol/L, respectively. It increased with age gradually from the minimum level, which was (4.18 ± 0.05)mmol/L in aged 18 to 29 group, till reached the maximum, which was (4.94 ± 0.05)mmol/L in aged 60 to 69 group, and then it declined to (4.92 ± 0.06)mmol/L in aged 70 group. The prevalence of hypercholesterolemia and borderline high cholesterolemia were 5.6%(95%CI:4.5%-6.6%) and 24.7%(95%CI:21.6%-27.9%) totally; 5.1% (95%CI:4.1%-6.1%) and 24.4% (95%CI:21.0%-27.6%) for male, 6.0% (95%CI:4.7%-7.3%) and 25.1%(95%CI:21.8%-28.4%) for female; 6.0%(95%CI: 5.0%-7.0%) and 27.7%(95%CI:24.9%-30.6%) in big cities, while 5.5%(95%CI: 4.2%-6.7%) and 24.2%(95%CI:20.5%-27.9%) in small and medium-sized cities. The minimum prevalence of hypercholesterolemia was in aged 18 to 29 group and maximum in aged 70 group, which were 2.2%(95%CI: 1.4%-3.0%) and 10.3%(95%CI: 7.1%-13.4%), respectively; while the lowest borderline high cholesterolemia prevalence was in aged 18 to 29 group and the highest in aged 60 to 69 year group, which were 12.9%(95%CI: 10.4%-15.4%) and 37.6% (95%CI: 33.6%-41.6%), respectively.

CONCLUSIONThe serum total cholesterol level and the prevalence of hypercholesterolemia and borderline high cholesterolemia were high among urban adults in China from 2010 to 2012, and more attention should be paid for high serum total cholesterol level among older adults.

Objective: This study was to analyze the association of lipid parameters with insulin resistance of Chinese elderly population in different glycemic status. Methods: Data were from China National Chronic Diseases and Nutrition Survey (2015). A total of 15 535 participants aged 60 and above who had completed survey questionnaire, physical examination, fasting blood biochemistry and insulin measurements were included in this study. According to the American Diabetes Association (2010) criteria, the participants were divided into normal glucose regulation, pre-diabetes, newly-diagnosed diabetes and previously-diagnosed diabetes. Multivariable logistic regression was preformed to assess the effects of lipid parameters on insulin resistance in different glycemic among the elderly population. Results: The proportion of normal glucose regulation, pre-diabetes, newly-diagnosed diabetes and previously-diagnosed diabetes was 50.46% (n=7 839), 22.19% (n=3 448), 12.46% (n=1 937) and 14.88% (n=2 311), respectively. The risk of insulin resistance increased with the elevated per quartile of triglycerides (TG) (OR=1.48,95%CI: 1.35-1.62), non-high-density lipoprotein cholesterol (Non-HDL)/HDL-C (OR=1.23, 95%CI: 1.12-1.35) and TG/HDL-C (OR=1.50, 95%CI: 1.36-1.65) and decreased with the elevated per quartile of HDL-C (OR=0.83, 95%CI: 0.76-0.90) after multivariate adjustment among normal glucose regulation participants. As for pre-diabetes participants, the risk of insulin resistance increased with the elevated per quartile of TG (OR=1.26, 95%CI: 1.14-1.39) and TG/HDL-C (OR=1.38, 95%CI: 1.24-1.54) and decreased with the elevated per quartile of HDL-C (OR=0.79, 95%CI: 0.71-0.87). The risk of insulin resistance increased with the elevated per quartiles of TG/HDL-C (OR=1.29, 95%CI: 1.12-1.48) among newly-diagnosed diabetes. As for previously-diagnosed diabetes, the risk of insulin resistance increased with the elevated per quartile of TG, Non-HDL/HDL-C and TG/HDL-C with adjusted OR(95%CI) about 1.28 (1.16-1.41), 1.37(1.21-1.55) and 1.51 (1.33-1.72) repsectivley and decreased with the elevated per quartile of HDL-C (OR=0.77, 95%CI: 0.67-0.87). Conclusion The relationship between lipid parameters and insulin resistance presented diversely in different glycemic status. The elderly with normal glucose regulation and previously-diagnosed diabetes should pay close attention to the change of TG/HDL-C, TG, HDL-C and Non-HDL/HDL-C. As for prediabetes participants, the TG/HDL-C, TG and HDL-C level change should be focused.

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.
