ABSTRACT
Objective To investigate the incidence of atherosclerotic renal artery stenosis (ARAS), the relationship between ARAS and cerebral artery stenosis, and the risk of ARAS in patients with brain infarction. Methods The clinical data of 1 650 brain infarction patients were analyzed, which were carried out digital subtraction angiography(DSA) of cerebral and renal artery.The incidence of ARAS was counted out, and the relationship was analyzed between the different degree and number of cerebral artery stenosis and the rate of RAS. The demographic characteristics and the common risk factors of atherosclerosis were recorded, and the risk factors of ARAS were analyzed. Results The rate of ARAS in moderate stenosis group and severe stenosis and occlusion group of cerebral artery were all significantly higher than that in mild stenosis group and no stenosis group (all P < 0.01). The rates of ARAS in severe stenosis and occlusion group were significantly significantly higher than those in moderate stenosis group (P < 0.01). The rates of ARAS in 2 branch stenosis group and ≥3 branch stenosis group were both significantly higher than those in no stenosis group and 1 branch stenosis group (P < 0.01). The rates of ARAS of ≥3 branch stenosis group were significantly higher than those in 2 branch stenosis group (P<0.05). The rate of ARAS of 1 branch stenosis group were significantly higher than those in no stenosis group (P < 0.05). Age, hypertension, moderate or more artery stenosis or occlusion, and≥2 branch stenosis was independent risk factor of ARAS. Conclusions The incidence of ARAS increasesd with the increase of the degree of cerebral artery stenosis and the number of branch involved.Older age, hypertension, moderate or more artery stenosis or occlusion, and≥2 branch stenosis is risk factor for ARAS.
ABSTRACT
As one of the types of metabolomic studies, targeted metabolomics is often used to determine precisely and accurately a limited number of pre-defined metabolites. In targeted metabolomic studies, metabolite groups with different structures and functions, such as lipids, carnitines, purine and pyrimidine, or amino acids, are investigated. Accurate quantification of targeted metabolites can make metabolomic studies more comprehensive and reliable, which is helpful to study the mechanism of diseases and achieve the purpose of disease warning, guidance, evaluation and treatment. In this review, the focus is on the application of targeted metabolomics to study metabolite groups with different structures and functions.
ABSTRACT
Diabetes mellitus is a typical metabolic disease.Its complications cause the main damage and lead to high mortality and disability eventually.The exact mechanism of diabetes is still unknown at present,and no radical cure of it is available.Therefore,the prevention of diabetes has become a priority.Metabolomics as a new technology can identify and measure the entire metabolic changes in the organism,and therefore has been widely applied to diabetes related studies with its enormous potential.
ABSTRACT
Objective To observe the abnormity of heart function in rats with pressure overload-induced left ventricular hypertrophy and the changes of NCX,SERCA2a expression in myocardial tissues. Methods Cardiac hypertrophy was induced by clipping the abdominal aorta in rats. The cardiac hypertrophy was evaluated by Left ventricular weight index(LVWI,left ventricular weight/body weight). NCX, SERCA2a mRNA and protein expressions in left ventricular tissues were determined by half-quantitative RT-PCR and Western blot normalized to abundance of GAPDH mRNA and protein,respectively. Results LVSP and LVEDP were obviously enhanced(P
ABSTRACT
Disdvantages of chemotherapy in treating breast cancer were insensitivity or intolerance.There were different opinions on chemotherapy in treating negative axillary lymph notes or positive hormone receptors after breast cancer surgery.The advantages of TCM in treating breast cancer were:there were many Chinese medical oncologists who had rich clinical experiences in treating breast cancer before and during surgery,before and during chemotherapy,before and during radiotherapy and during the consolidation period;treatment according to syndrome differentiation with TCM for different stages of breast cancer had been gradually standardized;a well developed network of academic information provided a good platform for establishing the unified treatment protocols with TCM for different stages of breast cancer.It was indicated that large scale prospective clinical trials with TCM in the treatment of after-surgery breast cancer patients who had negative auxillary lymph notes and positive hormone receptors should be carried out.
ABSTRACT
Five min coronary artery occlusion followed by reperfusion in rats could produce arrhythmias which were rapid in onset & of short duration. The incidences of VT & VF being 100% & 72% respectively. Quinidine & dauricine reduced the incidence & severity of VT significantly; and abolished VF. Tetrandrine could reduce the incidence of VF significantly, but it had no significant effect on the incidence of VT.
ABSTRACT
The distribution of properdin factor B (Bf)allotypes and their gene frequencies in 81 patients with systemic lupus erythematosus (SLE) was investigated using high voltage agarose gel electrophoresis and subsequent immunofixation, in an attempt to define whether specific Bf allotypes were associated with the disease. An increase in gene frequency of Bf F in the patients with SLE (0.1914) was found in comparison with that in the controls (0.1159), P_(correct)
