Coronary stent implantation is an important approach for treating and improving coronary artery disease, myocardia ischemia, and coronary revascularization. However, the biocompatibility of stent with host affects the long-term efficacy. In this study, we reviewed the studies on the factors and mechanism of vascular endothelialization after stenting and the medicine prevention. Stenting may cause vessel wall lesions, vascular intima tearing, allowing activation of coagulation system and leading to thrombogenesis. Plenty of white blood cells aggregates in the lesion sites that triggers inflammatory reactions, and migration of smooth muscle cells results in proliferative response, leading to intima hyperplasia. Drug-eluting stenting can prevent and cure vascular restenosis post stenting, inhibit the proliferative response caused by migration of smooth muscle cells and stimulate intima expansion. Vascular endothelialization post-stenting and novel stent design are important for the treatment of cardiovascular diseases.

Objective:To study the pharmacokinetic process ofbrucine from normal and ultra-micro powder ofsemen strychni in rat serum.Methods:HPLC techniques were used.All pharmacokinetics parameters were calculated with a 3P87 program.Results:The pharmacokinetics results indicated that the normal powder and the ultra-micro powder ofsemen strychni belonged to two compartment open model.The absorb ofbrucine was just several ten minutes, and there was no obvious difference ofTmax between normal powder and ultra-micro powder.This showed that:Brucine was some material that was easily absorbed.But we can find that Cmax increased from(51.13?0.48)?g/L to(69.26?1.40)?g/L after ultra-micro powder preparation which was quite obvious.K,Ka,B and ? had a obvious increase(P

Objective:Dissolution test was applied to study the dissolution rates of strychnine from the normal and ultramicro powder of semen strychi. Methods:HPLC techniques was used to detect the dissolution amount and the dissolution velocity of strychnine from the normal and ultra-micro powder of semen strychi. Results:The dissolution velocity of strychnine from the ultra-micro powder was higher than that from the normal powder,but there was no difference in the dissolution amount 4 hours later. Conclusion:The dissolution velocity of strychnine from the ultra-micro powder increased greatly and there was no loss of the principal active.

Objective To monitor ventilator-associated event (VAE) for the first time in an intensive care unit (ICU) in China,understand the applicability,incidence,and clinical significance of VAE in China.Methods Targeted monitoring on VAE was performed among patients ≥18 years and with mechanical ventilation (MV)＞2 days in the ICU of a hospital between January 2014 and September 2015,incidence of VAE was calculated,and patients were grouped according to whether or not they had VAE,prognostic factors were analyzed statistically.Results A total of 1 004 patients were monitored,the total hospital stay was 13 795 days in patients who used ventilator,307 (30.58％) cases of VAE occurred,incidence of VAE per 1 000 ventilator-days was 22.25.Univariate analysis showed that patients with VAE had longer length of ICU stay and MV,and higher mortality rate than patients without VAE when they moved out of ICU (all P＜0.05).Multivariate logistic regression analysis showed that VAE was independent risk factor for length of ICU stay,duration of MV,as well as mortality when patients moved out of ICU(all P＜0.05).Conclusion Judgment of VAE is based on MV parameters,it is more objective and accurate.There is a high incidence of VAE among ICU patients,it may lead to poor clinical outcomes,and has good values for the targeted monitoring on ICU patients in large comprehensive hospitals of China.

Objective:To investigate the detection rate of motoric cognitive risk(MCR)syndrome and explore the possible risk factors at different age groups.Methods:A total of 561 patients from geriatric outpatient clinic of Hubei Provincial Hospital of Traditional Chinese Medicine from November 2018 to December 2019 were divided into two age groups under 70 years old(n=241)and 70 years old and above(n=320). The general information, Pittsburgh Sleep Quality Index, Geriatric Depression Scale-15(GDS-15), 4-meter walking test, Mini-Mental State Examination and Morse Fall Scale were collected.Patients with MCR were screened out according to the MCR diagnostic criteria.Logistic multiple regression analysis was used to analyze the associated risk factors.Results:7 cases(7/241, 2.9%)met the MCR diagnostic criteria in age<70 years group, and 34 cases(34/320, 10.7%)in age ≥ 70 years group.The proportion of hearing impairment complaints and GDS-15 scores of MCR patients were higher than those of the non-MCR group in age<70 years group, and the Morse Fall Scale of MCR patients was higher than that of the non-MCR group in age ≥70 years old group( P<0.05). After adjusting for associated confounding factors, multiple logistic regression analysis showed that hearing impairment complaints( OR=26.394, P<0.05)and GDS-15( OR=1.385, P<0.05)were independent risk factors for MCR in age<70 years group.And female( OR=0.445, P<0.05)was a protective factor for MCR in age ≥70 years old group. Conclusions:Motoric cognitive risk syndrome has different risk factors in different age groups, which may indicate that the causes and predictive significance of MCR in these two different age groups are different.
