ABSTRACT
Objective: To explore the changes and benefits of vascular endothelial cell function in rats with qi deficiency and blood stasis syndrome, and the effect of Yiqi Huoxue recipe (YQHXF) of such changes. Method: Rats were randomly divided into blank control group, Qi deficiency and blood stasis group, and YQHXF high and low dose groups (5.54,2.77 g·kg-1). A small platform of water environment was used to make the rats stand for a long-term with irregular and incomplete sleep deprivation, 16 h per day for six weeks, so that both mentality and labor of rats were consumed to establish qi deficiency and blood stasis rat models. From the fifth week, intragastric administration was given for 2 weeks, until end of the experiment. Then levels of endothelin-1(ET-1), von willebrand factor (vWF), vascular cell adhesion molecule-1(VCAM-1), intercellular adhesion molecule (ICAM-1), P-selectin,interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in rat plasma were detected by enzyme-linked immunosorbent assay (ELISA) and nitric oxide (NO) was detected by nitrate reductase assay. Result:Compared with blank control group, rats in Qi deficiency and blood stasis group showed rough and dark hair, with significantly decreased body weight and pulse amplitude (PPPα were abnormally increased after sleep deprivation (PPPPPPPConclusion:Sleep deprivation can induce the formation of Qi deficiency and blood stasis syndrome in rats, and lead to vascular endothelial dysfunction. YQHXF has the function of protecting the vascular endothelium. It can improve the Qi deficiency and blood stasis symptoms in rats with Qi deficiency and blood stasis syndrome by regulating the secretion of vascular endothelial active substances, reducing cell adhesion and inhibiting inflammation.
ABSTRACT
Objective:To investigate the protective effect of Yiqi Huoxue recipe on rats with cerebral ischemia injury by using oxidative stress injury as an entry point. Method:SD rats were randomly divided into model group, sham operation group, nimodipine group (20 mg·kg-1), Yiqi Huoxue recipe high, medium and low dose group (2.916,1.458,0.729 g·kg-1). After 14 days of stomach, acute cerebral ischemic injury model was established by ligation of bilateral common carotid arteries. Ultrasound of synapse was observed by transmission electron microscopy. Total superoxide dismutase (T-SOD) and dialdehyde (MDA), lactate dehydrogenase (LDH), glutathione peroxidase (GSH-Px), horizontal adenine nucleoside triphosphate (ATP) levels were detected by biochemical method.

ABSTRACT
Based on our research team's clinical and basic research results of traditional Chinese medicine (TCM) in the prevention and treatment of ischemic stroke, and combined with TCM syndrome standard manifestations of this disease, wind, phlegm, fire, deficiency and blood stasis, this paper points out definitely that the basic pathogenesis of ischemic stroke is blood stasis caused by deficiency of both Qi and Yin. The pathogenic characteristics are deficiency in origin and excess in superficiality, and the wind, fire, phlegm, deficiency and blood stasis are related one another resulting in this disease; it is established that the basic syndrome types of this disease are deficiency of both Qi and Yin and static blood blocking the collaterals, and the therapeutic regime is a recipe including the TCM ingredients having the actions of nourishing yin, tonifying Qi and improving blood circulation (Yangyin Yiqi Huoxue) and according to the patient's individual variation of syndrome differentiation, the ingredients in the recipe can be added or subtracted. In this report, a new system of treatment for ischemic stroke based on syndrome differentiation is proposed.
ABSTRACT
Objective@#To investigate the role and mechanism of action of Yiqi Huoxue Recipe (YQHXR) in regulating autophagy and reversing liver fibrosis in rats with carbon tetrachloride (CCl4)-induced liver fibrosis.@*Methods@#Healthy male Wistar rats were intraperitoneally injected with a mixture of CCl4 (30%) and olive oil (70%) twice a week for 8 weeks to establish a rat model of liver fibrosis. The rats administered normal diet were used as control group. Furthermore, YQHXR or Fuzheng Huayu Recipe (FZHYR) was intragastrically administered to the rats. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured using an automatic biochemical analyzer. Hematoxylin-eosin (HE) staining and Masson staining were performed to observe the degree of fibrosis in rat liver. The protein expression of α-smooth muscle actin (α-SMA) and type I collagen α1 chain (Col1A1) in liver tissue was measured by immunohistochemistry. Furthermore, the mRNA and protein expression of α-SMA, Col1A1, autophagy-related protein 7 (Atg7), microtubule-associated protein 1 light chain 3 (LC3), and ubiquitin-binding protein (SQSTM1/p62) were determined using qRT-PCR and Western blotting, respectively. Comparison between multiple groups was made by one-way analysis of variance, and comparison between any two groups was made using the LSD test. P < 0.05 was considered as statistically significant.@*Results@#The YQHXR group and FZHYR group had significantly lower serum levels of ALT and AST than the model group (ALT: 66.8±10.42 U/L and 73.2±10.33 U/L vs 106.80±18.24 U/L, F = 31.672, P < 0.001; AST: 122.6±16.65 U/L and 125.4±16.92 U/L vs 278.4±66.14 U/L, F = 25.539, P < 0.001). The pathological grades of hepatic fibrosis were S5.64±0.22, S3.70±0.35, and S3.90±0.34 in the model group, YQHXR group, and FZHYR group, respectively (F = 362.188, P < 0.001). Compared with the control group, the YQHXR group and FZHYR group had significantly reduced mRNA and protein expression of α-SMA, Col1A1, Atg7, and LC3B and significantly increased expression of p62 (all P < 0.05), and the differences were greatest in the YQHXR group.@*Conclusion@#YQHXR and FZHYR can prevent or reverse liver fibrosis by regulating hepatocyte autophagy and inhibiting hepatic stellate cell activation and collagen deposition.

ABSTRACT
Objective To observe the effect of Yiqi Huoxue Recipe on the expression of TGF-?1 and ?-IFN in rats with radiation-induced lung injury in different radiation time, and discuss the prevention and curative effect of Yiqi Huoxue Recipe and its possible action mechanism. Methods One hundred and twenty Wistar rats were randomly allocated into irradiation group (n =30), irradiation with Yiqi Huoxue Recipe-treated group (n =30), irradiation with ambroxol-treated group (n =30) and normal control group (n =6). The former three groups were irradiated at right hemithorax with a dose of 30 Gy (5 Gy per week). Animals were followed for 26 weeks after the first irradiation. The levels of serum TGF-?1 and ?-IFN of 6 rats in each group were assayed by ELISA at the end of 4th, 6th, 8th, 12th and 26th week after the first irradiation. Results In Yiqi Huoxue Recipe-treated group, the levels of serum TGF-?1 were significantly lower from the 4th week than that of the irradiation group (P0.05). Conclusion Yiqi Huoxue Recipe can inhibit the excretion of TGF-?1 and promote the excretion of ?-IFN. It suggested that Yiqi Huoxue Recipe might play an important role in the prevention and curation of radiation-induced lung injury.
