Objective To investigate the changes and the correlation between the levels of plasma lysophosphalidic acid(LPA),acid phospholipid(AP),low density lipoprotein(LDL) and carotid artery atherosclerosis in patients with acute cerebral infarction(ACI).Methods The levels of plasma LPA,AP and LDL were examined in 67 ACI patients and 30 normal controls,the carotid arteries were investigated with B mode ultrosand.Results The levels of plasma LPA,AP and LDL were higher in ACI group than those in the normal control group(all P

Objective To investigate the impact of hemoglobin(Hb)level on the risk of all-cause mortality in elderly patients with stable coronary artery disease(SCAD)treated by percutaneous coronary intervention(PCI).Methods A retrospective cohort study was conducted on 195 elderly SCAD patients treated by PCI in our hospital from June 2016 to December 2017,a total of 180 case were followed up.They were divided into four groups based on quartiles of Hb levels:Q1 group[≤122(108.28±12.53)g/L,n=47],Q2 group[122＜Hb≤137(130.07±4.33)g/L,n=43],Q3 group[137＜Hb≤148(142.67±3.10)g/L,n=46],and Q4 group[＞148(158.36±8.50)g/L,n=44].Their clinical data were collected and compared among the groups.All patients were followed up,with all-cause mortality as endpoint.Cox regression analysis was used to evaluate the impact of Hb level on all-cause mortality in elderly SCAD patients treated by PCI.Results For the 180 patients with complete follow-up,the median follow-up time was 703(415,1121)d,and the incidence of all-cause mortality was 10.00％(totally 18 deaths).And the incidence was 25.50％(12 deaths),7.00％(3 death),4.30％(2 deaths)and 2.30％(1 death)in Q1,Q2,Q3,and Q4 groups,respectively,with statistically significant differences(P＜0.01).Univariate Cox regression analysis showed age was a risk factor for all-cause death(P＜0.01),while Hb level,BMI,smoking history,dyslipidemia,and aspirin use were a risk facotr for all-cause death(P＜0.05,P＜0.01).Further multivariate Cox regression analysis revealed Hb level was a risk facotr for all-cause death(HR=0.96,95％CI:0.93-0.99,P＜0.01).The risk of all-cause mortality was 3.68 times higher in the Q1 group than the Q2 group(HR=3.68,95％CI:1.01-13.45,P＜0.05),and there was no correlation in the incidence between the Q3 and Q4 groups(P＞0.05).Conclusion Low Hb level is an independent predictor for all-cause mortality in elderly SCAD pa-tients after PCI.

Laughing gas (Nitrogen monoxide) is currently abused due to its low price and easy availability. This article discussed the clinical manifestations of a patient with subacute combined degeneration of the spinal cord caused by inhalation of laughing gas. The patient developed numbness of extremities, unstable walking, and decreased serum vitamin B 12 level. MRI of the cervical spine showed abnormal signals in the lateral and posterior cords of the cervical spinal cord (C2-6) , neuroelectrophysiological examination showed peripheral nerve damage in the extremities. After treatment with vitamin B 12 supplementation, the patient's condition gradually improved. Clinicians diagnose subacute combined degeneration of the spinal cord, especially when the patient has no gastrointestinal disease, diet, malnutrition, etc., they need to carefully inquire about the history of nitrous oxide inhalation to avoid missed diagnosis.

Objective:To investigate the prognostic significance of anemia in elderly patients with stable coronary artery disease treated by percutaneous coronary intervention(PCI).Methods:In this retrospective cohort study, 180 patients with stable coronary artery disease aged ≥60 years undergone percutaneous coronary intervention and with complete clinical data, admitted to Nanjing Meishan Hospital between June 2016 and December 2017, were selected.Baseline clinical data of the patients were collected, including hemoglobin, C-reactive protein, lipids, fasting glucose, glycated hemoglobin, blood creatinine, and left ventricular ejection fraction on cardiac color ultrasound.The endpoints of the follow-up included major adverse cardiac events(MACE), such as all-cause death, non-fatal myocardial infarction, and non-fatal stroke.According to the hemoglobin level, participants were divided into an anemia group(n=32)and a non-anemia group(n=148). Clinical data of the two groups were compared, and the Kaplan-Meier method and multivariate analysis with the Cox regression method were used to evaluate the effect of anemia on the occurrence of MACE in elderly patients with stable coronary artery disease treated by PCI.Results:The median duration of the follow-up of the 180 patients was 702.5 days and MACE occurred in 27(15.0%). Compared with the non-anemia group, the anemia group had a higher age, C-reactive protein level and MACE ratio, lower levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol and the glomerular filtration rate, and higher proportions of patients with smoking history and patients with dyslipidemia( P<0.05). Kaplan-Meier curves suggested that the incidence of MACE in the anemia group was higher than that in the non-anemia group[37.5%(12/32) vs.10.1%(15/148), P<0.05]. Multivariate analysis with the Cox regression method showed that the risk of MACE in the anemia group was 2.91 times higher than that in the non-anemia group( HR=2.91, 95% CI: 1.13-7.48, P<0.05). Conclusions:Anemia is an independent predictor of MACE in elderly patients with stable coronary artery disease after PCI.
