OBJECTIVE: To investigate the influence of acute blood stasis on nitric oxide(NO), angiotensin Ⅱ(Ang Ⅱ), angiopoietin-like protein 4(ANGPTL4)m RNA, neuregulin 1(NRG-1) m RNA, and platelet endothelial cell adhesion m...OBJECTIVE: To investigate the influence of acute blood stasis on nitric oxide(NO), angiotensin Ⅱ(Ang Ⅱ), angiopoietin-like protein 4(ANGPTL4)m RNA, neuregulin 1(NRG-1) m RNA, and platelet endothelial cell adhesion molecule-1(PECAM-1) in rats with stasis induced by high-molecular-weight dextran(HMWD).METHODS: Seventy-five Sprague Dawley rats were divided randomly into five groups(n = 15 in each group): control group, immediate group, 1 h group,3 h group, and 6 h group. A model of acute blood stasis was established via injection of HMWD into the tail vein. After performing electrocardiogram at the predetermined times according to the grouping, we collected blood and cardiac samples for hematoxylin-eosin(HE) staining and histopathological examination via transmission electron microscopy. Enzyme-linked immunosorbent assay was used to detect plasma levels of NO, AngⅡ, and fibrinogen. Real-time polymerase chain reaction was used to detect the expression of ANGPTL4 m RNA and NRG-1 m RNA. Immunohistochemical methods were used to detect PECAM-1 protein expression.RESULTS: The rat model of blood stasis showed blood retention in the capillary lumens. The ST segment showed gradual elevation, and was still elevated at 3 and 6 h after induction of blood stasis.HE staining showed myocardial cell necrosis and dissolution after modeling, along with basement membrane rupture and mitochondrial structural damage. Transmission electron microscopy showed endothelial cell swelling and an increase in absorption vesicles immediately after modeling. Endothelial cell apoptosis was increased at 3 and 6 h after modeling. Cardiac muscle fibers were disordered and intercalated discs were blurred immediately after modeling. There were massive numbers of dissolved cardiac muscle fibers, ruptured basement membranes, and mitochondrial structural damage at 3 and 6 h after modeling. NO plasma concentration was significantly reduced immediately and 1 h after modeling, while it was increased at 3 and 6 h.AngⅡ plasma concentration was decreased immediately after modeling, but increased at 1, 3, and6 h. Fibrinogen plasma concentration was significantly increased at immediate, 1, 3, and 6 h after modeling. PECAM-1 protein expression was obviously increased immediately after modeling, at 1, 6 h was found mild augment. Expression of Ang PTL4 m RNA was increased at immediate, 1, 3, and 6 h after modeling, and was found further augment at 3,and 6 h. Expression of NRG-1 m RNA was increased at immediate, 1, 3, and 6 h after modeling, and the strongest expression was at 1 h.CONCLUSION: The pathological manifestation of acute blood stasis is characterized by microvascular blood retention. Prolonged blood stasis leads to worsening endothelial cell and cardiomyocyte damage, along with imbalances in the expression of vasomotor factors and increased vascular tone.The pathological damage caused by blood stasis also promotes the expression of cell protection factors.展开更多

METHODS Patients with tubal infertility were di- vided randomly into two groups： 58 patients in the treatment group and 57 in a control group. The treated patients took Jiutengzhuyu tablets orally for 25 days. The control group received an intrauter- ine infusion of 5 mg dexamethasone sodium phos- phate, 4000 units of chymotrypsin, 80 000 units of gentamicin sulfate dissolved in 20 mL of normal sa- line at I mL/min. After 3 months of treatment, the curative effect on tubal patency was assessed and a l-year follow-up visit was used to document any pregnancies. RESULTS The total effective rate was 78% in the treatment group and 32% in the control group with a statistically significant difference （x2=24.57, P〈0.01）.CONCLUSION： Jiutengzhuyu was effective in treat- ing infertility caused by tubal infertility with a Traditional Chinese Medicine diagnosis of blood stasis.展开更多

METHODS: 138 PBC patients who met the inclusion criteria were divided into 3 groups according to the stage of disease development: group A(group of basic normal), group B(group of symptom stage) and group C(group of decompensation stage). Each group collected 46 cases, and every patient was reexamined, which included blood routine examination, liver function test, image ultrasound examination, autoantibody examination and immunoglobulin test. Then, the patients' clinical symptoms were observed and recorded, and their constitution of traditional Chinese medicine were classified. RESULTS:(1) For 138 patients with PBC, their TCM constitution was characterized by biased constitution, among which constitution of Qi stagnation(19.57%) was the majority, which was followed by constitution of Qi asthenia(15.94%), constitution of Yin asthenia(15.94%) and constitution of damp-heat(14.49%). There was no significant correlation between the type of constitution and the age of onset(P>0.05).(2) The constitution types of group A and B were mainly constitution of Qi stagnation, constitution of Qi asthenia and constitution of damp-heat, while group C was mainly composed of constitution of blood stasis, constitution of Yin asthenia and constitution of Yang asthenia.(3) The highest positive rate of autoantibodies in patients with PBC was constitution of Qi stagnation, which was followed by constitution of damp-heat, constitution of Yin asthenia and constitution of Qi asthenia. The most abnormal liver function and immunoglobulin were constitution of Qi stagnation, which was followed by constitution of Qi asthenia, constitution of Yin asthenia, constitution of damp-heat.CONCLUSION: Constitution of Qi stagnation, constitution of Qi asthenia, constitution of damp-heat and constitution of Yin asthenia were the susceptible constitutions of PBC patients.展开更多
