Noninfectious diarrhea is a kind of digestive disease caused by many factors and the main clinical features are increased frequency of defecation and change of character of stool,most of the patients have intestinal microecological imbalance. Improving the intestinal microecological balance is very important in the treatment of noninfectious diarrhea. Microbial ecological agent(MEA)has definite efficacy for the treatment of noninfectious diarrhea,and gradually becomes the commonly used drug for noninfectious diarrhea in clinical practice. This article reviewed the use of MEA in the treatment of noninfectious diarrhea.

Hypoxia-inducible factor-1(HIF-1) is a heterodimer of an O2-rugulated ?subunit and a constitutively expressed ?subunit.The article reviews the active expression of HIF-1 and its important role in angiogenesis induced by tissue hypoxia/ischemia.

In the last 10 years,an increasing interest has been devoted to the study of endothelial progenitor cells(EPCs).Alteration and/or reduction of the circulating EPCs have/has been associated with different manifestation of cardiovascular disorders.Thererfore,EPCs have been extensively studied as biomarkers of cardiovascular disease and as a cell-based therapy for repair of damaged blood vessels.In the review,we focus on two methodologies used to identify and enumerate EPCs in the majority of studies up to date.

Autophagy is a ubiquitous physiological process that occurs in all eukaryotic cells.It can be induced by starvation,ischemia/reperfusion injury and heart failure.Rational autophagy in cardiac cells during ischemia/reperfusion helps to keep cellular homeostasis,and inhibit the cell loss.However,inappropriate activation of autophagy leads to cell death.

It was show that the 3 medical preparations, viz: Chuanxiong, the mixture of Chuanxiong & Ginseng ( CG Mixture ) , and the mixture of Chuanxiong & Miltiorrhizae could increase the coronary retrograde flow & decrease the resistance to collateral flow. The CG mixture exhibited positive effects on cardiac output, coronary flow blood, & retrograde pressure, but the other 2 medicines showed negative effects.These findings suggest that the CG mixture could improve & regulate the cardiovascular function, open the collateral vessels to reduce the ischemic size, while the other 2 medicines might reduce the cardiac power consumption. It is expected that the CG mixture may be more suitable for treatment of coronary diseases with cardiac insufficiency & hypotension, and the other 2 may be used for that with hypertension.

These groups of Chinese medicines were prepared-Cbuanxiong, a mixture of Chuanxiong & Ginseng, & a mixture of Chuanxiong & Miltorrhiza. The effects of these groups of drug on sischemic areas ( subepicar-dial ) and ( subendocardial) PO2 were compared in anaesthetized open-chest mongrel dogs. The heart tissue P02 was determined simultaneously at a depth of 2-3mm(epicardial) and 8-9mm (endocardial) 晈ith small platinum electrodes by polarography. The 3 combinations of medicine could not only increase the heart tissue PO2 in both areas when ischemia occured, but also increase deep area P02 to a greater extant than superficial area PO2. Lignsticum Chuanxiong and Panax Ginseng were more effective than the other 2 groups.

Aim To detect the effect of a combination of extracts of ginseng and ginkgo biloba(Naoweikang,NWK) on acetylcholine,monoamines and their metabolites in ?-amyloid peptide(A?)_(1-40) treated rats and the potential mechanisms.Methods A 1-month NWK(15.5,31 and 62 mg?kg~(-1),respectively) administration to rats was performed daily after bilateral injection of A?_(1-40)(4 g?L~(-1) for each side) into hippocampus.Acetylcholine(ACh) was determined with an improved HPLC-ECD method,which is combined with two immobilized enzyme reactors.Monoamines and their metabolites were also determined with HPLC-ECD.Result Compared with shams,ACh and serotonin(5-HT) in whole brains in models decreased significantly(P

Objective To establish the normal reference value range of hematological and serum biochemical parameters in Beagle dogs for our own research center and to supply references for establishing the national standard.Methods CV Beagle dogs aged 4～6 months were selected as the investigative objects.Of the Beagle dogs,263 were male with body weight of(8.09?0.78)kg,263 were female with body weight of(6.84?0.87)kg.Blood was collected from cephalic vein at the endgame of the experiment,then both hematological and serum biochemical parameters were measured.The acquired data were analyzed by the "Independent-Samples T Test" process of SPSS V 13.0.Regarded the males and the females as two independent samples,the difference between sexes was also compared.Results The mean normal reference values and the standard deviation of hematological and serum biochemical parameters in both male and female Beagle dogs were obtained by analysis.Conclusions Comparison of sexes showed that there exists obviously difference between male and female Beagle dogs referring to 3 serum biochemical parameters of T-Bil,GLU and ALB.

This study was aimed to observe the effect ofRong-Shuan (RS) capsule on rodent tolerance against cerebral ischemia, hypoxia and cerebral reserve capacity, which was related to promote blood circulation and remove blood stasis. Acute cerebral ischemia and anoxia models were established by permanent left carotid artery ligation on C57 BL/6 mice and hypoxia inhalation (O2?N2 = 8?92) for 15 min. Duodenal administration of RS capsule at different doses (100, 200 or 400 mg·kg-1) or saline were given 10 min after ischemia onset. The local brain blood circulation changes and neurobehavioral function were evaluated 24 h after ischemia onset. SD rats were given RS capsule at different doses (75, 150, 300 mg·kg-1) or saline. The effect of RS capsule on improvement of microcirculation disturbance induced by high molecular dextran was observed. The results showed that compared with the sham operation group, the brain blood circulation in the model group was significantly decreased; the cerebral infarction area increased; and the behavioral score after cerebral hypoxia was significantly increased (P < 0.05, orP < 0.01). Meanwhile, after the injection of high molecular dextran among rats in the model group, the cerebral leptomeninx microcirculation was obviously slowed down at 3 timepoints, which were 10, 20 and 30 min. Compared with the model group, RS capsule (400 mg·kg-1) can significantly increase the local blood circulation in the brain of mice, improve behavioral disturbance, reduce cerebral ischemia area (P< 0.05, orP < 0.01). RS capsule can also improve blood flow velocity and flow pattern in cerebral leptomeninx microcirculation disturbance induced by high molecular dextran at different timepoints (P < 0.05, orP < 0.01). It was concluded that RS capsule can increase the tolerance against cerebral ischemia, hypoxia and cerebral reserve capacity in order to protect the neural tissues to promote neuronal recovery.

This study was aimed to observe behavioral changes of post-stroke depression (PSD) rats, and to assess effect ofJie-Du Tong-Luo(JDTL) capsule onqi-supplementing and depression-relieving. Microspheres were injected from external carotid artery of rats under anesthesia to prepare the multiple cerebral infarction. Aftermid long term feeding, PSD rat model was established. Then, open-field test (OFT), tail suspension test (TST), forced swimming test (FST) and glucose preference test were employed to study behavioral changes of rats. The results showed that rats suffered multiple cerebral infarction after mid long term feeding formed PSD, which were indicated by reduced food consume, slow body weight increasing, reduction of spontaneous movement and inquiry activity, prolonged accumulative immobility time in TST, FST and lowered glucose preference, compared with rats in the normal group. Compared with the model group, rats in the JDTL capsule group andBu-Chang Xin-Nao-Tonggroup showed larger body weight increase, higher scores in OFT, reduced immobility time in TST, FST, and elevated glucose preference. It was concluded that JDTL capsule had significant efficacy on rats’ body weight, behavior and glucose preference, which might be its pharmacological basis onqi-supplementing and depression-relieving.
