METHODS AMI model formatted by electricity to irritate the left ventricular branch of coronary artery of open-chest rabbit,and observation aspects including electrocardiogram(ECG),cardiac output and contractility,serumal enzymatic activities and biochemistry and pathology of lipid peroxide extent of myocardial infarction zone. RESULTS By urinate kinase(UK) combining with injection tanshin,abnormal changes of ECG, descending of cardiac contractiles and cardiac output,going up of serum cardiac damage enzyme(CPK-MB and LDH),and the malondialdehyde(MDA)of serum and myocardial infarction zone could be remarkably reduced or avoided during UK dissolving the thrombus to cure AMI rabbits. CONCLUSION Injection tanshin can clearly reduce or avoid lipid peroxidation damage during UK dissolving the thrombus to cure the acute myocardial infarction.

C-reactive protein(CRP)is the most sensitive indicator of acute phase proteins.A growing body of evidence suggests that atherosclerosis,as a main cause of cerebral infarction,is a chronic inflammtory process.The present studies have found that the CRP levels and genetic polymorphisms are associated with atherosclerosis and cerebral infarction.As compared with coronary artery disease,the association between high-sensitive CRP and ischemic stroke is more closely.This article reviews the advaces in research on the biological characteristics of CRP,the factors influencing CRP levels,the CRP levels and the correlation between genetic polymorphisms and cerebral infarction.

Vascular endothelial growth factor is a vascular endothelial cell-specific mitogen.It is the most important angiogenic factor.VEGF expresses highly after cerebral infarction.It plays importmt roles in angiogenesis and neuroprotection.At the same time,its overexpression will also increase vascular permeability;thereby it may aggravate brain edema.This article reviews the advances in research on VEGF and its receptors and cerebral infarction.

Objective To investigate the clinical and MR features of fungal encephalopyosis and fungal granuloma.Methods The clinical and MR data of 10 cases with fungal encephalopyosis and fungal granuloma confirmed by surgical pathology or clinical serum were analyzed retrospectively.Then we analyzed the clinical conditions,MR signals,lesion enhancement,DWI and MRS performance characteristics of the 10 cases.Results Six cases were fungal encephalopyosis,among which 2 cases occurred in the sella turcica after surgery which located in and above the sella turcica.2 cases occurred in the frontal lobe after frontal surgery and 1 case of them was multiple encephalopyosis.2 cases of encephalopyosis without operation history were located in the left frontal lobe and right cerebellum respectively.The abscess walls of these cases were thin and showed high tension.Furthermore,it had annular significant signal enhancement and high signal in DWI scan.One case of huge fungal granuloma located in the frontal lobe and into the sinuses which showed uneven signal enhancement. The Cho level was significantly increased.Three cases of cryptococcal granuloma showed multiple lesions located in the bilateral basal ganglia region and 2 out of them accompanied with cephalomeningitis.Conclusion The MR performance of fungal encephalopyosis was quite similar with bacterial brain abscesses,which makes the differential diagnosis difficult.The brain fungal granuloma MRS may display a significant increase of Cho level which might be related with gliosis.It shows certain characteristics of brain MR performance of cryptococcal granuloma which are multiple lesions,preferential distribution of basal ganglia region and accompanying cephalomeningitis.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.
