Objective To analyze the relationship of red blood cell distribution width(RDW)and blood lipid metabolism indicators with carotid atherosclerotic plaque stability in elderly patients with acute cerebral infarction(ACI).Methods A total of 110 elderly ACI patients admitted in our hospital from March 2021 to November 2024 were retrospectively recruited,and according to their carotid plaque characteristics,they were divided into stable plaque group(48 cases)and unstable plaque group(62 cases).The RDW,and levels of TC,TG,HDLC,LDL-C and homocysteine(Hcy)were detected.Results The unstable plaque group had significantly higher levels of RDW,TC,TG,LDL-C and Hcy,but lower HDL-C level than the stable plaque group(P＜0.01).RDW,TC,TG,HDL-C,LDL-C and Hcy were the influencing factors of carotid atherosclerotic plaque stability in elderly ACI patients(P＜0.05,P＜0.01).ROC curve analysis suggested that the AUC value of combined detection of RDW,TC,TG,HDL-C,LDL-C and Hcy in evaluating the stability of carotid atherosclerotic plaque was 0.940(95％CI:0.898～0.983),and the combination had bet-ter efficiency than single indicator detection(P＜0.05).Conclusion RDW and blood lipid metabo-lism indicators are associated with the stability of carotid atherosclerotic plaque in elderly ACI patients,and they can be used as biochemical evaluation indicators for the stability.

Objective To review the clinical manifestation,diagnosis method,misdiagnosis,risk factors,treatments and prognosis of Stanford B aortic intramural hematoma (IMHB).Methods All of the Stanford B aortic IMHB patients admitted in Wuhan Union hospital from January 2008 to December 2013 were analyzed.The clinical manifestation,diagnosis method,misdiagnosis,managements and prognosis were studied.Furthermore,the effect and long-term survival of different therapies were compared,including medical treatment and endovascular repair.The statistics was performed with SPSS 16.0.Results There were 36 B aortic IMHB patients,and the percent of male patients was 72.22％.The mean age of IMHB was 60.19 ± 11.12.Most patients complained of acute chest and back pain,accompanied with hypertension.Twenty-eight patients (77.78％) received medication therapy,among them,there were 5 patients died of aortic rupture; eight patients (22.22％) received endovascular surgery,one died of cerebral hemorrhage (12.5％).No difference was found between medication therapy and endovascular surgery (17.86％ vs 12.5％,P ＞0.05).Conclusions For simple type B aortic IMHB patients,medication therapy and a dynamic monitoring of full aortic CT angiography was recommended,and for pejorative patients the endovascular treatment should be taken actively.

The etiology of deep vein thrombosis (DVT) is still not elucidated nowadays.Based on the accordance between DVT incidence and the anemophilous pollen concentration in the air,we proposed the hypothesis that allergic reaction induced by anemophilous pollen may cause “idiopathic” DVT,and proinflammatory factors may play an important role in the thrombosis process.
