Research progress of no reflow phenomenon in patients with acute myocardial infarction during primary percutaneous coronary intervention / 中国医师杂志

Primary percutaneous coronary intervention is a main treatment for acute myocardial infarction.Although there is vast majority of patients with coronary artery to restore blood flow after percutaneous coronary interventional therapy opened the infarction related artery,no reflow phenomenon is frequently observed and seriously affect the prognosis of patients.The occurrence of no reflow in percutaneous coronary intervention (PCI) is associated with a variety of factors and the pathogenic mechanisms that cause this phenomenon are complex and interrelated.So a better understanding of these mechanisms could judge the possibility of no-reflow and promote the development of individualized prevention and treatment strategies are of great clinical significance for the prevention of no-reflow.

Effect of different doses of monocrotaline in combination with isopropylarterenol on the hemodynamic response, heart index and right heart hypertrophy index in rats / 中国比较医学杂志

Objective To study the effect of different doses of monocrotaline in combination with isopropylarterenol on the hemodynamic resonse, heart index and right heart hypertrophy index in rats.Methods Sixty-four healthy adult SD rats, male:female=1∶1, body weight 200-250 g, were randomly divided into blank control group (n=16) and three model groups (n=16 in each group).The high dose model group (n=16) received i.p.injection of monocrotaline 80 mg/kg once and epinephrine 10 mg/kg once daily for one week.The moderate dose group received i.p. injection of monocrotaline 55 mg/kg once and epinephrine 8 mg/kg once daily for one week.The low dose group received i. p.injection of monocrotaline 30 mg/kg once and epinephrine 3 mg/kg once daily for one week.The rats were fed for 6 weeks, and then pulmonary artery pressure and right ventricular pressure were tested and heart index and right ventricular hypertrophy index were determined.Results Compared with the control group, the mean pulmonary artery pressure and right ventricular systolic blood pressure in the low dose monocrotaline group were not significantly changed, but significantly changed in the moderate dose monocrotaline group ( P<0.05) .The heart index and right ventricular hypertrophy index in the low dose monocrotaline group were not significantly changed, but in the moderate dose monocrotaline group, the heart index was significantly reduced ( P<0.01 ) and the right ventricular hypertrophy index was significantly increased ( P<0.05 ) .Conclusions The use of a single injection of 55 mg/kg monocrotaline in combination with continuous injection of 8 mg/kg isopropylarterenol once daily for one week can ensure the survival rate of rats, and the successful formation of pulmonary artery hypertension, leading to heart weakness.

Semantic construction of EHR information model in big data background / 中华医学图书情报杂志

The semantic construction of EHR information model has experienced a developmental process from es-tablishing core data set and modeling to two-level modeling, which are usually used in combination in construction of information models at present. In general, the framework (reference model), necessary elements (core data set) and technical specifications for EHR information model were first established when its top architecture was de-signed, which was followed by the establishment of different medical concepts, subjects and special archetypes for different departments according to the framework standards.

Preparation of biodegradable and sustained release gel of tinidazole / 生物医学工程学杂志

The objective of this study was to prepare a biodegradable poly (DL-lactide) injectable gel of tinidazole. The formulation parameters evaluated in this study included polymer molecular weight, polymer concentration, solvent and drug loading, and orthogonal design was used to optimize the formulation. The preferable formulation was that 30% (w/w) poly(DL-lactide) (MW is 5 700) dissolved in 70% (w/w) N-methyl-2-pyrrolidone with 4%-6% (w/w) tinidazole.
