Objective:To investigate the correlation between the ratio of apolipoprotein B to apolipoprotein A-I (ApoB/ApoA-I) and unstable carotid plaque in a neurologically healthy population receiving health check-ups.Methods:This cross-sectional study consecutively enrolled 1 149 neurologically healthy individuals who underwent physical examinations at the Health Management Centre of Beijing Tiantan Hospital, Capital Medical University, from October 2021 to September 2022. All eligible participants completed standardized questionnaires, physical examinations and laboratory tests. Laboratory tests of lipid metabolism-related biomarkers included total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), ApoA-I, and ApoB; non-high-density lipoprotein cholesterol and the ApoB/ApoA-I ratio were subsequently calculated. The carotid plaque stability was evaluated using superb microvascular imaging technology. The participants were classified into unstable plaque group (341 cases) and stable plaque group (808 cases) according to the presence or absence of intraplaque neovascularization. The univariate and multivariate logistic regression analyses were used to explore the correlation between the ApoB/ApoA-I ratio and unstable carotid plaques.Results:The study enrolled 1 149 participants totally, with a median age of 57 (49-63) years, including 771 males (67.10%) and 378 females (32.90%), and 341 cases (29.68%) were found with unstable carotid plaques. The unstable plaque group had a higher proportion of males, smoking history, diabetes history, along with higher waist-to-hip ratio and ApoB/ApoA-I ratio compared to the stable plaque group [76.54% vs 63.12%, 33.43% vs 22.77%, 19.06% vs 13.37%, 0.91 (0.85, 0.94) vs 0.89 (0.84, 0.93), 0.64 (0.51, 0.76) vs 0.59 (0.48, 0.72)], while HDL-C and ApoA-I levels were lower [1.39 (1.19, 1.63) vs 1.44 (1.24, 1.66) mmol/L, 1.43 (1.29, 1.60) vs 1.51 (1.36, 1.68) g/L] (all P<0.05). An elevated ApoB/ApoA-I ratio was positively associated with the risk of unstable carotid plaque ( OR=1.61, 95% CI: 1.13-2.29, P=0.008; P for trend<0.001). After adjusting for age, gender, waist-to-hip ratio, history of hypertension, history of diabetes, dyslipidemia, cardiovascular disease, history of smoking and estimated glomerular filtration rate, the positive association between elevated ApoB/ApoA-I ratio and the risk of unstable carotid plaque remained significant ( OR=1.48, 95% CI: 1.01-2.16, P=0.044; P for trend=0.004). Conclusion:In a neurologically healthy population receiving health check-ups, an elevated ApoB/ApoA-I ratio may increase the risk of unstable carotid plaque.

Objective:To investigate the association of Subclinical Carotid AtheroSclerosis (SCAS) and prediabetes or Diabetes Mellitus (DM)in the healthy people.Methods:From September 2018 to June 2019, participants who underwent physical examination in the Health Management Center of Beijing Tiantan Hospitial were enrolled consecutively. The baseline characters were collected prospectively. Carotid Ultrasound was evaluated by radiologists according to the standard operating protocol. Univariable analysis and multivariable logistic analysis were used to estimate the association of prediabetes or DM with SCAS.Results:Totally 401 participants were eligible and enrolled. The mean age was (52.2±10.4) years and 43.7% (252/401) of them were females. The prevalence of DM and SCAS were 16.4% (66/401) and 48.9% (196/401) respectively. In the univariate analysis, elder age (≥60 years old) ( OR=5.93, 95% CI: 3.86-9.09, P<0.001), hypertension ( OR=2.76, 95% CI: 1.84-4.15, P<0.01), prediabetes( OR=1.67, 95% CI: 1.08-2.58, P<0.05) and DM ( OR=3.60, 95% CI: 1.97-6.58, P<0.01), cigarettes smoking ( OR=2.64, 95% CI: 1.82-3.81, P<0.001), lower HDLlevel<1.04 mmol/L ( OR=1.58, 95% CI: 1.04-2.42, P<0.001) and hyperhomocysteinemia (≥15 μmol/L)( OR=1.69, 95% CI: 1.17-4.04, P<0.01) were associated with higher prevalence of SCAS. On the contrary, female sex ( OR=0.53, 95% CI: 0.39-0.74, P<0.001) was associated with lower prevalence of SCAS. In the multivariable logistic analysis, elder age(≥60 years old) ( OR=6.04, 95% CI: 3.13-11.7, P<0.01), hypertension ( OR=2.14, 95% CI: 1.13-3.87, P<0.05), cigarettes smoking ( OR=2.19, 95% CI: 1.21-3.98, P<0.05) and DM ( OR=2.32, 95% CI: 1.16-4.67, P<0.05) were associated with SCAS independently. The association between prediabetes and SCAS was not statistically significant. Conclusions:DM is independently associated with SCAS in neurological healthy people, while prediabetes tended to increase the risk of SCAS.

Objective To investigate the effects of antibiotic prophylaxis on the incidence of infection and prognosis in acute phase aftersevere stroke. Methods 165 patients within 24 h from clinic onset were divided into the intervention group and control group. The interventionincluded cefuroxime+metronidazole or moxifloxacin. The body temperature was continuously monitored, and the presence of infectionwas daily assessed with C-reactive protein (CRP), leukocyte count, and bedridden X-ray. They were also assessed with Glasgow ComaScale (GCS) and Acute Pathologic and Chronic Health Evaluation (APACHE)-Ⅱ. Primary end points was incidence of infection; secondaryend points included death and other clinical outcome. Results There was no difference between tow groups in infection rate (P=0.58), intervaluntil diagnosis of infection (P=0.74), so as mortality (P=1.00) and interval of death (P=0.84), body temperature (P=0.99), CRP (P=0.37) , leukocyte (P=0.51), scores of GCS (P=0.31) and APACHE-Ⅱ (P=0.28). Conclusion Antibiotic prophylaxis works little to prevent infectionand improve outcome in patients with acute stroke.
