A rapid UFLC–MS/MS method for simultaneous determination of formononetin, cryptotanshinone, tanshinone IIA and emodin in rat plasma and its application to a pharmacokinetic study of Bu Shen Huo Xue formula

Bu Shen Huo Xue formula (BSHX) is a traditional Chinese medicine prescription used for clinical treatment of chronic kidney diseases. A rapid and selective Ultra fast liquid chromatography with tandem mass spectrometry (UFLC-MS/MS) method was developed for simultaneous determination of four bioactive components of BSHX including formononetin, cryptotanshinone, tanshinone IIA, and emodin in control and unilateral ureteral obstruction (UUO) model rat plasma for the first time. Atorvastatin was used as the internal standard (IS). Plasma samples were extracted by liquid-liquid extraction with ethyl acetate. The chromatographic separation was carried out on a Shim-pack XR-ODS III column with a gradient mobile phase consisting of acetonitrile and 0.1% formic acid. The detection was performed on a triple-quad tandem mass spectrometer by multiple reaction monitoring (MRM) via electrospray ionization (ESI) source with positive ionization mode for formononetin, cryptotanshinone, tanshinone IIA, and negative mode for emodin. The method was linear for four analytes over the range of investigated concentration with all coefficients of determination (R(2)) greater than 0.9938. The lower limits of quantification (LLOQ) for formononetin, cryptotanshinone, tanshinone IIA, and emodin were defined as 0.3, 0.5, 1.5, and 0.3ng/mL, respectively. The rapid and sensitive method was fully validated and successfully applied to the pharmacokinetic study of formononetin, cryptotanshinone, tanshinone IIA and emodin in rats following oral administration of Bu Shen Huo Xue formula.

Effect of Bushen Yiqi Huoxue recipe on placental vasculature in pregnant rats with fetal growth restriction induced by passive smoking

Interactions of vascular endothelial growth factor (VEGF) with receptors VEGFR1/Flt1 and VEGFR2/Flk1, and those of angiopoietins (Ang-1, Ang-2) with receptor Tie2 play important roles in placental angiogenesis. This study investigated vascular morphology and expression of these angiogenic factors in rat placenta on the day 15, 18, 21 of gestation (D15, D18 and D21). The rats were randomly assigned into 3 groups: normal group, model group [fetal growth restriction (FGR) model], and Bushen Yiqi Huoxue (BYHR) recipe treatment group (BYHR group, the pregnant rats with FGR were treated with BYHR recipe). Morphological analysis indicated that during initial villous formation, fetal nucleated erythrocytes (FNEs) appeared in maternal blood sinus (MBS). Subsequently, FNEs were surrounded by endothelial cells to form fetal capillary (FC) and then by trophoblast cells to form villi. As pregnancy proceeded, FC density increased progressively with increasing endothelial identification staining (EIS) in normal and BYHR groups. Whereas, villous formation was suppressed, normal increase in FC density was impaired and EIS was weakened in model group. Quantitative PCR analysis showed that VEGF and Flk1 mRNA increased over gestation in all groups, indicating that VEGF might play a pivotal role in FC growth during late gestation. VEGF mRNA was increased on D15, while decreased on D21 in model group as compared with normal group and BYHR group. Immunohistochemically, Ang-2 protein was highly expressed in FNEs, gradually disappeared as villi matured, and decreased over gestation in all groups, indicating that Ang-2 might play a pivotal role in villous formation, which was further supported by decreased Ang-2 mRNA and protein expression in model group on D15. Ang-1 mRNA, Tie2 mRNA and Ang-1/Ang-2 ratio increased from D15 to D18 in all groups as placenta matured. Ang-1 mRNA, Tie2 mRNA and Ang-1/Ang-2 ratio were decreased on D18 in model group as compared with normal and BYHR groups, indicating delayed maturity of FGR placenta. Alterations in angiogenic factors may result in altered placental vasculature and cause placental insufficiency. BYHR recipe could balance the angiogenic factors to promote the formation and maturation of FGR placental vasculature.

The Effects of High-Dose Qinggan Huoxue Recipe on Acute Liver Failure Induced by D-Galactosamine in Rats

Qinggan Huoxue Recipe is a traditional Chinese medicine, which has been usually used to improve liver function in hepatitis. In order to investigate the effects of high-dose Qinggan Huoxue Recipe on acute liver failure and explore the potential mechanism, we had built acute liver failure models in rats by intraperitoneal injection of D-galactosamine (D-GalN). High-dose Qinggan Huoxue Recipe was delivered by gavage. After treatment, the blood alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), albumin (ALB), cholinesterase (CHE), and prothrombin time (PT) were determined. The pathological score of liver tissue was recorded. Proliferating cell nuclear antigen (PCNA) immunohistochemistry staining and fluorescence quantitative reverse transcription polymerase chain reaction (qRT-PCR) of high mobility group box 1 (HMGB1), toll-like receptor 4 (TLR4), nuclear factor-kappa B (NF-κB), and Caspase-3 were performed. The survival curve was also depicted. Our results demonstrated that high-dose Qinggan Huoxue Recipe could significantly improve liver function and increase survival rates in rats with acute liver failure. These effects were supposed to be mediated by suppressing inflammatory reaction and apoptosis.

Therapeutic effect of Bushen Huoxue Recipe (补肾活血方) on autoimmune premature ovarian failure mice established by immunization with recombinant porcine zona pellucida 4 antigen

To investigate the efficacy and mechanism of Bushen Huoxue Recipe (, BHR) in the treatment of murine autoimmune premature ovarian failure (POF). The recombinant porcine zona pellucida 4 (pZP4) was expressed in E. coli BL21 (DE3) strain within prokaryotic plasmid pET28a (+), purified by Ni-affinity chromatography and verified by Western blot. Murine autoimmune POF model was established by immunization with pZP4 of female BALB/c mice. Fifty POF mice were randomly divided into 5 groups, which were respectively given low (3.75 mg/kg), moderate (7.5 mg/kg), and high dose (15.0 mg/kg) of BHR by gastrogavage once daily for 20 days, with 17-β-estradiol (0.13 mg/kg) and normal saline as positive and negative control. Estrous cycles were analyzed through vaginal smears, serum estradiol (E) levels, and anti-pZP4 antibody titers were detected by ELISA. The proliferative responses in vitro of spleen lymphocytes to pZP4 antigen restimulation were measured by [(3)H]-thymidine incorporation, and the histomorphology changes of ovary were evaluated by optical microscope. The purified pZP4 was visible as a single lane with 14.4 kD in SDS-PAGE and Western blot. The murine POF model with lengthening estrous cycles, decreased levels of serum E2, high titers of serum anti-pZP4 antibody, and reduced ovarian follicles and corpus lutea were established by immunization with recombinant pZP4. Treatment with moderate and high dosage BHR significantly increased ovarian follicles and reduced the proliferation of spleen lymphocytes to the pZP4 antigen of POF mice (P <0.05). However, only the high dosage BHR administration significantly improved the estrous cycles, elevated the serum E levels (P <0.01), and decreased the serum anti-pZP4 antibody titers of model mice P<0.05). The recombinant pZP4 could evoke the antigen-specific immune response in mice and induce the autoimmune ovarian injury. It has been demonstrated that BHR was able to increase the serum E levels and protect ovarian functions from the autoimmune injury in murine POF model.

Key words: Qingre-Huoxue Recipe; Dampness-heat and blood-stasis syndrome; Rheumatoid arthritis

Effects of Yiqi Huoxue Recipe (益气活血方) and Coxsackie virus B type 3 on the expression of ribosomal protein S20 in rat cardiac myocytes

To study the effects of yiqi huoxue recipe and Coxsackie B virus type 3 (CVB3) on the expression of ribosomal protein S20 in rat cardiac myocytes, to explore the pathogenesis of myocarditis induced by CVB3 and the mechanism of yiqi huoxue recipe on gene level, and to further investigate whether yiqi huoxue recipe is an effective prescription for CVB3 myocarditis. A modified suppression subtractive hybridization (SSH) was used to isolate differentially expressed genes between the CVB3 infection group and the treatment group with yiqi huoxue recipe. The results were further verified by fluorescence RT-PCR. The results of SSH showed that the gene expression of ribosomal protein S20 in the treatment group was higher than that in the CVB3 infection group (P<0.05), which agreed with the results of fluorescent RT-PCR. Down-regulation of ribosomal protein S20 mRNA expression might be one of the mechanisms in CVB3 myocarditis, and yiqi huoxue recipe could achieve the treatment of viral myocarditis by regulating the expression of ribosomal protein S20.

Effects of Chinese herbal medicine Yiqi Huoxue Formula on TGF-β/smad signal transduction pathway and connective tissue growth factor in rats with renal interstitial fibrosis

To observe the effects of Yiqi Huoxue Formula (YQHXF), a compound Chinese herbal medicine, on transforming growth factor-β (TGF-β)/smad signal transduction pathway and connective tissue growth factor (CTGF) in rats with renal interstitial fibrosis Unilateral ureteral obstruction (UUO) rat model was established and the rats were randomly divided into 5 groups: untreated group, high-, medium-, and low-dose YQHXF groups and fosinopril sodium group. Another group with sham operation was set as control. All rats were administered with corresponding drugs for 3 weeks. After the last administration, each rat was sacrificed and weighed and the serum was separated for creatinine (Cr) and blood urea nitrogen (BUN) detection. Kidneys of the rats were taken out, and mRNA and protein expressions of TGF-β, smad2, smad7 and CTGF were measured with real-time fluorescent quantitative reverse transcription-polymerase chain reaction and Western blotting respectively; fibrosis of the kidney tissue was observed with hematoxylin-eosin (HE) staining and Masson trichrome staining. Compared with sham-operation group, Cr and BUN in serum of UUO groups were increased, while high-dose YQHXF treatment decreased the UUO-induced increase of Cr and BUN levels. HE staining and Masson staining results showed that the renal tubular epithelial cells in untreated group got atrophied; lumens of renal tubules expanded; fibroplastic proliferation and inflammatory cell infiltration were observed in renal interstitium; the number of glomerulus decreased and collagen increased significantly compared with sham-operation group. In the high- and medium-dose YQHXF groups and fosinopril sodium group, the histopathological changes of inflammatory cell infiltration, fibroplastic proliferation, expansion of lumens of renal tubules was improved as compared with the untreated group. The mRNA and protein expressions of TGF-β, smad2 and CTGF in untreated group were higher than those in sham-operation group (P<0.05), and the mRNA and protein expressions of smad7 in untreated group were lower than those in the sham-operation group (P<0.05). Compared with untreated group, high- and medium-dose of YQHXF significantly down-regulated the mRNA and protein expressions of TGF-β, smad2 and CTGF (P<0.01, P<0.05), and up-regulated the mRNA and protein expressions of smad7 (P<0.01, P<0.05). The mRNA expression of CTGF in UUO rats may be regulated by TGF-β/smad signaling transduction pathway. YQHXF might inhibit the expression of CTGF through down-regulation of TGF-β and smad2 and up-regulation of smad7, thus inhibiting the progression of renal interstitial fibrosis.

Effects of Bushen Huoxue Formula on the Learning and Memory Function and the Cerebral Neurotransmitters in Diabetic Mice

To observe the effects of Bushen Huoxue Formula (Formula for reinforcing the kidney and activating blood circulation) on the learning and memory function and the cerebral neurotransmitters in diabetic mice. Forty ICR mice were randomized into the normal control group, model group, Nimotop group and Chinese medicine group, 10 mice in each group. Tail intravenous injection of alloxan was applied to prepare diabetic model. Four weeks later, intragastric administration of Bushen Huoxue Formula for the Chinese medicine group, Nimotop for the Nimotop group, and isometric distilled water for the other two groups were respectively given for 8 weeks. The changes in the blood sugar level were observed; the learning and memory function was detected by Morris labyrinth test; and the contents of norepinephrine (NE), dopamine (DA), 5-hydroxyltryptamine (5-HT) and 5-hydroxyl indole acetic acid (5-HIAA) in cerebral cortex were determined in mice of all the groups. The blood sugar levels in the diabetic model mice significantly increased as compared with those of the normal control group determined 72 h and 12 weeks later (P < 0.05 or P < 0.01). Latencies for Morris labyrinth test in the Nimotop group and the Chinese medicine group were significantly shortened as compared with that in the model group (P < 0.01). The contents of cortical NE in the Chinese medicine group was significantly higher than that in the model group (P < 0.01). Bushen Huoxue Formula can improve the learning and memory function in the diabetic mice, and the mechanism is possibly related with change of the cortical NE content.

Effects of cembrane-type diterpenes on proliferation of PC12 cells and their antagonistic effects on neurotoxicity induced by glutamate

To investigate the effects of cembrane-type diterpenes extracted from Sinularia flexibilis on the proliferation of PC12 cells and their protective effects on PC12 cells exposed to glutamate. Methyl thiazolyl tetrazolium (MTT) method was adopted to observe the effects of cembrane-type diterpenes (compound 1, compound 2 and compound 3) on the proliferation of PC12 cells. And the protective effects of the three compounds on PC12 cells exposed to glutamate were also detected by MTT. Furthermore, the influence of compound 1 on intracellular concentration of calcium in PC12 cells exposed to glutamate was detected by laser confocal microscopy. After 72-hour PC12 cell culture, OD values in the 2, 10 and 50 micromol/L compound 1 groups were significantly higher than that in the normal group (P<0.05, P<0.01). After 24-hour glutamate damage, OD values in the 0.4, 2 and 50 micromol/L compound 1 groups, the 0.4, 2 and 100 micromol/L compound 2 groups and the 2 micromol/L compound 3 group were obviously increased as compared with the untreated group (P<0.01, P<0.05). After 48-hour glutamate damage, OD values in the compound 1 group were approximate to those in the normal control and the positive control group while were significantly higher than that in the untreated group (P<0.01, P<0.05), but no dose-dependent effect was observed. Compound 1 of 0.4, 2, 50 micromol/L could significantly reduce the intracellular concentration of calcium in PC12 cells exposed to glutamate (P<0.05, P<0.01), which was also approximate to the effect of nimodipine (positive control drug). Cembrane-type diterpenes (compound 1, compound 2 and compound 3) extracted from Sinularia flexibilis have obvious protective effects on PC12 cells damaged by glutamate, and compound 1 has the best neuroprotective effect. The mechanism of the neuroprotective effect of compound 1 may lie in reducing the intracellular concentration of calcium in PC12 cells exposed to glutamate and relieving the calcium overload.

Effects of Qinggan Huoxue Recipe and its separated recipes on urokinase-type plasminogen activator and plasminogen activator inhibitor-1 fibrinolytic system in rats with alcoholic liver fibrosis

To study the action mechanisms of Qinggan Huoxue Recipe (QGHXR), a compound traditional Chinese herbal medicine, and its separated recipes by observing their effects on expressions of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) in rats with alcoholic liver fibrosis (ALF). A total of 150 SD rats were divided into three groups: blank group, carbon tetrachloride (C(4)) group and ALF-inducing group. Rats in the ALF-inducing group were administered with a mixture diet (56% alcohol 10 mL/kg, corn oil 2 mL/kg, pyrazole 25 mg/kg) once daily and intraperitoneally injected with 0.3 mL/kg 25% solution of C(4) in olive oil twice weekly. The C(4) group was intraperitoneally injected with equal volume of C(4) and olive oil as the ALF-inducing group and ingested normal saline (12 mL/kg per day). The blank group was intraperitoneally injected with and ingested saline in equal volumes of the above. At the end of the eighth week, the survived rats in the ALF-inducing group were divided into four subgroups: untreated group, QGHXR group, Qinggan Recipe (QGR) group and Huoxue Recipe (HXR) group. The three treated groups were given corresponding drugs respectively (4.75, 1.5, 3.25 g/kg). The blank group, CCl(4) group and untreated group were given normal saline in equal volume (5 mL/kg per day). All rats were anaesthetized and killed at the end of the twelfth week. The activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum were analyzed. Pathological changes in liver tissues were observed by hematoxylin and eosin staining and Masson staining. The expressions of uPA and PAI-1 were evaluated with Western blotting, immunofluorescence, and real-time polymerase chain reaction. There existed obvious liver fibrosis in liver tissues in the untreated group as compared with the blank group (P<0.01), and the activities of ALT and AST and the expressions of uPA and PAI-1 also increased in the untreated group. QGHXR and its separated recipes could improve the degree of liver fibrosis (P<0.01). QGHXR and its separated recipes could degrade the activity of ALT as compared with the untreated group; QGHXR and its separated recipes advanced the expression of uPA, and decreased the expression of PAI-1 significantly as compared with the untreated group. The effect of QGHXR was the best among the three recipes. QGHXR and its separated recipes may improve ALF in rats by decreasing the expression of PAI-1 and advance the expression of uPA. The effect of QGHXR is the best among them.

Bushen Jianpi Huoxue Recipe in prevention and treatment of tibial stress injuries in rabbits

To explore the effects of Bushen Jianpi Huoxue Recipe, a compound traditional Chinese herbal medicine for tonifying the kidney, invigorating the spleen and promoting blood circulation, on tibial stress injuries in rabbits. Thirty-five mature male rabbits were used in the experiment, and randomly divided into 7 groups: sedentary control (SC) group, 1-week exercise (E-1W) group, 2-week exercise (E-2W) group, 3-week exercise (E-3W) group, 4-week exercise (E-4W) group, 3-week exercise and 1-week Chinese herbal medicine treatment (EMT-1W) group, and 4-week exercise and 2-week Chinese herbal medicine treatment (EMT-2W) group. There were 5 rabbits in each group. A rabbit model of tibial stress injuries was established by stimulating the rabbits to jump and run within a high-voltage and low-current electronic cage. Radiologic features, bone scintigraphy, histology and electron microscopy of rabbit tibia were observed, and the content of blood parathyroid hormone (PTH), bone gla protein (BGP) and testosterone was detected by using radioimmunoassay method. After 2-week exercise, changes in histology and osteocytes had a tendency towards stress injuries. Serum PTH and BGP levels were remarkably increased, while serum testosterone level was lower than that in the SC group. Three- and four-week continuous exercise resulted in tibial stress injuries, and the positive changes were observed in X-ray features and radionuclide images. Compared with E-3W group, the levels of serum BGP and testosterone were decreased remarkably. A series of positive results such as prevailing negativeness of X-ray features and radionuclide images, increasing process of osteogenesis, typical osteogenic phase of osteocytes and favorable transformation of biochemical markers was shown in EMT-1W and EMT-2W groups. It also showed remarkable rising levels of serum BGP and testosterone and remarkable reducing level of serum PTH in EMT-1W and EMT-2W groups as compared with E-1W and E-2W groups. Bushen Jianpi Huoxue Recipe can prevent and treat exercise-induced tibial stress injuries by stimulating new bone formation and increasing serum testosterone level.

Wenyang Huoxue Recipe up-regulates the expression of angiopoietin-1 mRNA in rats with chronic aristolochic acid nephropathy

To investigate the effects of Wenyang Huoxue Recipe (WRHXR), a compound traditional Chinese herbal medicine for warming yang and promoting blood flow, on the expression of angiopoietin mRNA in rats with chronic aristolochic acid nephropathy induced by Caulis Aristolochia Manshuriensis (CAM) decoction, and to explore the protection mechanism of WYHXR against kidney damage. Twenty-eight male SD rats were randomly divided into normal control group, CAM group and WYHXR-treated group. Rats in the normal control group (n=8) and CAM group (n=10) were intragastrically administered with normal saline 10 ml/(kg.d) or CAM decoction 10 ml/(kg.d) respectively. Rats in the WYHXR-treated group (n=10) were intragastrically administered with WYHXR 30 g/(kg.d) and CAM decoction 10 ml/(kg.d). The expressions of Ang-l and Ang-2 mRNAs were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) after 20-week treatment. Compared with the normal control group, the expression of Ang-l mRNA was significantly decreased, and the expression of Ang-2 mRNA was significantly increased in the CAM group (P<0.01). Compared with the CAM group, the expression of Ang-l mRNA was increased in the WYHXR-treated group (P<0.01). The expression of Ang-2 mRNA had no significant difference between the CAM group and the WYHXR-treated group (P>0.05). Renal pathology showed that renal damage in WYHXR-treated group was significantly reduced as compared with the CAM group. WYHXR can up-regulate the expression of Ang-l mRNA, which may be its action mechanism in protecting the kidneys.

Preventive and therapeutic effects of Bushen Huoxue Recipe on autoimmune premature ovarian failure in mice

To investigate the preventive effect of Bushen Huoxue Recipe (BSHXR), a compound traditional Chinese herbal medicine, on autoimmune premature ovarian failure (POF) in mice. Ovarian antigen was prepared with the ovarian tissue of female BALB/c mice. A mouse model of POF was established by immunization injection of the ovarian antigen of isotype female mice on multiple subcutaneous sites and two posterior soles. The POF mice were treated with BSHXR after the first and third immunization. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in peripheral blood were detected by enzyme linked immunosorbent assay. Lymphocyte infiltration was appeared in ovarian stroma of POF mice. The levels of FSH and LH were evaluated and the E(2) level was decreased significantly (P<0.05). BSHXR could reduce the increased levels of FSH and LH, increase the level of E(2) and the number of growing and mature follicles. The efficacy of early treatment was better than that of late treatment. BSHXR can recover ovarian function in POF mice mainly by regulating the indiscriminate hormone level, and BSHXR has preventive effect on autoimmune POF in mice.

Effect of Yiqi Huoxue Recipe (益气活血方) on cardiac function and ultrastructure in regression of pressure overload-induced myocardial hypertrophy in rats

To investigate the effect of Yiqi Huoxue Recipe (YHR) on the cardiac function and ultrastructure during the regression of myocardial hypertrophy induced by pressure overload in rats. The model of myocardial hypertrophy was established by abdominal aortic banding. Eighty male Wistar rats were divided into six groups, the normal control group I (n=20), the normal control group II (n=12), the hypertension model group I (n=12), the hypertension model group II (n=12), the YHR group (n=12) and the Captopril group (n=12). The observation was carried out in the normal control group I and the hypertension model group I after 4 weeks of modeling, and the other four groups were observed after 16 weeks of modeling (12 weeks of administration). The cardiac function was measured with a multichannel biological signal analysis system, and the myocardium ultrastructure was observed by a transmission electron microscope. (1) Compared with the normal control group I, the systolic blood pressure and cardiac coefficient (left ventricular weight/body weight) in the model I group was higher (P<0.05, P<0.01). (2) In the YHR group, cardiac coefficient and -dp/dt(max) were lower, left ventricular systolic pressure and +dp/dt(min) were higher when compared with the model group II and the Captopril group (P<0.05 or P<0.01). In the Captopril group, only cardiac coefficient was lower when compared with the mode group II (P<0.05). (3) Compared with the normal control group II, +dp/dt(max) was higher (P<0.01) -dp/dt(max) and isovolumetric contraction time (ICT) was lower (P<0.05, P<0.01) in both the YHR group and the Captopril group. (4) Results of the myocardium ultrastructure showed edema under myocardium plasmalemma, enlarged sarcoplasmic reticulum and T tube, and significantly enlarged intercalated disc of the cardiac muscle in the model groups. In the Captopril group, the extension of sarcoplasmic reticulum and T tube as well as the pathological changes of intercalated disc were lighter, with slight edema under the myocardium plasmalemma. In the YHR group, the expansion of the sarcoplasmic reticulum was less than in the Captopril group, part of the pathological changes of intercalated discs was slightly more severe than that in the Captopril group, the dissolution of nuclear chromatin was not found, which was similar to that of the Captopril group, and no injury of the nucleus was found, either. YHR could reverse myocardial hypertrophy in rats with abdominal aortic banding and improve the systolic and diastolic function of the left ventricle. The ultrastructure of the myocardium such as arcoplasmic reticulum, intercalated disc, and cell nucleus in abdominal aortic banding rats could be partly reversed by the recipe.

Effects of Jianpi Bushen Huoxue Recipe on hematopoietic cell apoptosis in a mouse model of aplastic anemia

Adopting methods of cell culture to explore the effects and mechanisms of Jianpi Bushen Huoxue Prescription (JPBSHXP), a traditional Chinese compound herbal medicine for strengthening spleen, reinforcing kidney and activating blood circulation, in inhibiting hematopoietic cells apoptosis in a mouse model of aplastic anemia (AA). Blood serum of AA mice was made from an AA mouse model. Blood serums containing different traditional Chinese compound herbal medicine were made from rats after intragastric administration of JPBSHXP and its related decoctions, respectively. Bone marrow cells of normal mice were incubated by these blood serums for 24 hours, respectively. The apoptosis of the bone marrow cells were assayed by flow cytometry and transmission electron microscopy (TEM). It was indicated that the bone marrow cells of normal mice incubated with blood serum of AA mice displayed typical apoptosis. The apoptosis rates of bone marrow cells of the AA mice incubated by blood serum containing different traditional Chinese herbal medicine were decreased. The effect of Bushen (reinforcing kidey) Recipe was better than Jianpi (strengthening spleen) Recipe and Huoxue (activating blood circulation) Recipe, while the effect of JPBSHXP was the best. TEM results showed that the effect of Bushen Recipe was better than that of the Jianpi Recipe and the Huoxue Recipe, while the effect of JPBSHXP was the best. JPBSHXP and its related decoctions can significantly decrease the apoptosis rate of bone marrow mononuclear cells of the AA mice. It is inferred that JPBSHXP can promote bone marrow hematogenesis.

Effects of Qinggan Huoxue Recipe and its decomposed formulas on CD14, Toll like receptor 4 and nuclear factor-κB expressed by Kupffer cells

To investigate the effects of Qinggan Huoxue Recipe (QGHXR), a compound Chinese herbal medicine, and its decomposed formulas Qinggan Recipe (QGR) and Huoxue Recipe (HXR) on expressions of CD14, Toll like receptor 4 (TLR(4)) and nuclear factor-kappaB (NF-kappaB) in Kupffer cells. The isolated primary rat Kupffer cells were treated with lipopolysaccharide (LPS) for a certain period of time, a series of concentrations of drug-containing serums of QGHXR and its decomposed formulas were added, the expressions of NF-kappaB, tumor necrosis factor-alpha (TNF-alpha), CD14, and TLR(4) of the Kupffer cells were detected in different culture conditions by using Western blot, real-time reverse transcription polymerase chain reaction (RT-PCR) and ELISA methods respectively. QGR could down-regulate the expression of membrane receptor CD14, but the expression of NF-kappaB and TNF-alpha were not significantly decreased after QGR treatment. HXR could down-regulate the expression of membrane receptor TLR4 and inhibit the expressions of NF-kappaB and TNF-alpha. QGHXR could down regulate the expressions of membrane receptors CD14 and TLR(4) and inhibit the expressions of NF-kappaB and TNF-alpha. QGHXR can protect liver cells by down regulating the expressions of CD14, TLR(4) and NF-kappaB and inhibiting TNF-alpha expression.
