Protective effect of an extract of Guipi Pill (归脾丸) against radiation-induced damage in mice

Objective:To study the protective effect of an extract of Guipi Pill(归脾丸) against radiationinduced damage.Methods:A total of 100 Kunming mice were randomly divided into normal group,model group,positive drug group(treated with radioprotective agent "523",5 mg/kg at 24 h before irradiation) and two treatment groups,with 20 mice in each group.The extract of water extraction-alcohol precipitation (WAP) from Guipi Pill were administered orally to the mice in the two treatment groups at the dose of 500 and 1,000 mg/kg,respectively,for 6 days prior to whole body radiation(8 Gy).Fifty mice with 10 in each group were used to observe the survival rate 30 days after radiation.The other 50 mice with 10 in each group were sacrificed on day 10 after radiation(6 Gy) in order to take blood,liver and unilateral femur.Results:Pretreatment prior to irradiation with WAP resulted in a significantly higher 30-day survival rate of mice after exposure to a potentially lethal dose of 8-Gy radiation.WAP could significantly increase the total white blood cell count and DNA content of bone marrow,and it also increased the activity of various antioxidant enzymes,such as superoxide dismutase,catalase,total antioxidant capacity and glutathione peroxidase in liver tissue of mice, which were reduced by radiation treatment.Maleic dialdehyde level and bone marrow micronucleus rate were significantly reduced by WAP,which were increased after 6-Gy radiation.Conclusion:WAP of Guipi Pill could increase the 30-day survival rate and the antioxidant capacity as well as protect bone marrow in mice.WAP of Guipi Pill is an effective radioprotective agent.     

叶绿酸铜钠对再生障碍性贫血小鼠间充质干细胞功能的影响

Objective: To investigate the effects of sodium copper chlorophyllin (SCC) on the proliferation, differentiation and immunomodulatory function of mesenchymal stem cells (MSCs) from mice with aplastic anemia. Methods: A mouse model of aplastic anemia was established by exposure of BALB/c mice to sublethal doses of 5.0 Gy Co60 γ radiation, followed by transplantation of 2×1000000 lymph node cells from DBA/2 donor mice within 4 h after radiation. Aplastic anemic BALB/c mice were randomly divided into six groups: the treated groups, which received 25, 50, or 100 mg/kg/day SCC, respectively; a positive control group treated with cyclosporine A (CsA); and an untreated model control group (model group); while, the non-irradiated mice as the normal control group. SCC or CsA were administered by gastrogavage for 20 days, starting on day 4 after irradiation. Peripheral blood cells were counted and colony-forming fibroblasts (CFU-F) in the bone marrow were assayed. The ability of MSCs to form calcium nodes after culture in osteoinductive medium was also observed. The immunosuppressive effect of MSCs on T lymphocytes was analyzed by enzyme-linked immunosorbent assay and flow cytometry, to evaluate the efficacy of SCC in mice with aplastic anemia. Results: Peripheral blood white cell and platelet counts were increased by medium and high SCC doses, compared with the untreated control. CFU-Fs were also increased compared with the untreated control, and the numbers of calcium nodes in MSCs in osteoinductive medium were elevated in response to SCC treatment. The percentage of Forkhead box protein 3 (FOXP3+) T cells was increased in T cell-MSC cocultures, and the cytokine transforming growth factor β1 was up-regulated in SCC-treated groups. Conclusion : The results of this study suggest that SCC not only promotes the proliferation and differentiation of MSCs, but also improves their immunoregulatory capacity in mice with aplastic anemia.     

加味竹叶石膏汤及其成分可预防大鼠放射性食管炎的发生

Objective:To investigate the effect of Modified Zhuye Shigao Decoction(加味竹叶石膏汤,MZSD)and its components on preventing radiation esophagitis of rats.Methods:One hundred Wistar rats were randomly divided into 5 groups,including the control group,radiation model group,MZSD group,Zhuye Shigeo Decoction(竹叶石膏汤,ZSD)group,and added Ingredients group,20 rats in each group.The model of radiation esophagitis of rat was established by once local radiation of 40 Gy(330 Mulmin)with a high energy linear accelerator.The administration of Chinese medicine was continued for 14 days from 7 days before radiation application in the three treatment groups.On the 7th and 14th day,the serum was isolated and the levels of inflammatory cytoldnes tumor necrosis factor(TNF-α),interleukin 1 13(IL-1β)and IL-8 were tested.The pathological slices of esophagus were obtained,and the pathological changes were observed.During the whole process,weight and food intake were recorded each day.Results:On the 7th day after radiation,the esophagus of rats in the MZSD group was almost intact,and the pathological injury score was significantly lower than that of the radiation model group,ZSD group and added ingredients group(P0.01).Compared with the control group,the body weight and food intake of rats in the radiation model group were significantly decreased,and the levels of TNF-α,IL-1β and IL-8 were significantly increased(P0.05 or P0.01),while the MZSD group showed a significant increase in body weight and food intake,and a significant decrease in the levels of TNF-α,IL-1β and IL-8 compared with the radiation model group,ZSD group and added ingredients group(P0.05 or P0.01).Conclusion:MZSD prevents the development of radiation esophagitis probably by inhibiting the generation and release of the inflammatory cytoldnes TNF-α,IL-1β and IL-8.     

抗骨疏不同提取物大鼠模型骨质疏松症的作用及其潜在机制

Objective： To investigate the preventive effects and possible underlying mechanism of different extracts of Kanggushu （抗骨疏） on osteoporosis in ovariectomized rats. Methods： One hundred and sixty- five female SD rats were divided into 11 groups： control, sham, model, Xianling Gubao Capsule （仙灵骨葆胶囊）, nilestriol, Kanggushu aqueous extract high-, medium-, and low-dose and suet extract high-, medium-, and low-dose groups. The osteoporosis model was made by ovariectomizing the rats. The latter 8 groups were administered intragastricly with Xianling Gubao Capsule, nilestriol, Kanggushu aqueous extract and suet extract for 12 weeks, respectively, while the other 3 groups were administered orally saline. The whole body bone mineral density, bone mineral content, organ coefficient of uterus, serum estradiol and alkaline phosphatase contents, blood calcium, phosphorus, interleukin 6 and bone Gla-protein levels after treatment were monitored. Additionally, three-point bending test of femur, HE staining, and scanning electron microscope were performed to explore the pharmacodynamics and underlying mechanisms. Results： In comparison with ovariectomized rats of model group, Kanggushu aqueous extract high-dose resulted in an increased bone mineral density, bone mineral content and organ coefficient of uterus, improved estradiol level, and improved maximum load and structural stiffness （P〈0.05 or P〈0.01）. Two-dimensional and thrae-dimensional trabecular structure was also observed under HE staining and scanning electron microscopy, and the number and thickness of trabecular bone in Kanggushu aqueous extract high-dose group was significantly increased compared to the model group, while the lipid droplets in bone marrow cavity were significantly less. However, there were no significant differences in blood calcium, total serum alkaline phosphatase and bone Gla protein among different treatment groups. Overall, the osteoprotective effects of Kanggushu aqueous extract were comparable to those of nilestriol and were significantly more effective than those of Xianling Gubao Capsule. Conclusion： The preventive effects of Kanggushu aqueous extract might be partly due to the increased estradiol level, accelerated restoration of bone trabecular reticulate structure, and accordingly increased bone mineral density in osteoporosis rats.

Objective:To investigate the effect of Ermiao Recipe(二妙方,EMR)with medicinal guide Angelicae Pubescentis Radix(APR)on the homing of bone marrow stem cells(BMSCs)to focal zone in osteoarthritis(OA)rats.Methods:Forty-eight Sprague-Dawley rats were randomly assigned to the sham-operated,model,EMR,and EMR plus APR groups(12 rats in each group).The OA rat model was induced by anterior cruciate ligament transection and medial meniscus resection.All rats were injected with recombinant human granulocyte colonystimulating factor[rhG-CSF,30μg/(kg-d)for continuous 7 days],and rats in the EMR and EMR plus APR groups were treated with EMR or EMR plus APR at 1.6 or 1.9 g/(kg·d)for 3 or 6 weeks,respectively.Cartilage histopathologic changes were observed by hematoxylin and eosin staining.Chondrocytes apoptosis and cartilage matrix components were tested by transferase-mediated deoxyuridine triphosphate-biotin nick end labeling assay and special staining,lnterleukin-1 B(IL-1β),tumor necrosis factorα(TNF-α),bone morphogenetic protein 2(BMP-2),and transforming growth factor beta-1(TGF-β_1)in serum were detected by enzyme-linked immunosorbent assay or radioimmunoassay assay.Matrix metalloproteinase(MMP)-13,tissue inhibitors of metalloproteinase(TIMP)-1,bromodeoxyuridine(BrdU),cluster of differentiation 34(CD34),and stromal cell derived factor 1(SDF-1)were measured by immunohistochemistry assay.Results:EMR and EMR plus APR significantly inhibited articular cartilage damage and synovium inflammation in OA rats at 3 or 6 weeks of treatment,the most obvious changes in these parameters were found in the EMR plus APR group.At 6 weeks,compared with EMR treatment,EMR plus APR remarkably inhibited chondrocytes apoptosis and the release of IL-1βand TNF-α,obviously decreased MMP-13 expression,and significantly increased expressions of proteoglycan,collagen,typeⅡcollagen and TIMP-1,serum levels of BMP-2 and TGF-β_1 as well as expressions of BrdU,CD34 and SDF-1 in cartilage articular(P0.01 or P0.05).Conclusion:The medicinal guide APR improved the therapeutic effects of EMR on OA rats by promoting directional homing of BMSCs to focal zone.     

Effects of Fufang Shenhua Tablet(复方肾华片) on the Expression of Toll-Like Receptors during Acute Kidney Injury Induced by Ischemia-Reperfusion in Rats

<正>Objective:To investigate the impact of a traditional Chinese medicinal compound known as Fufang Shenhua Tablet(复方肾华片,SHP) on the expression of Toll-like receptors(TLRs) during renal ischemia-reperfusion injury(IRI)-induced acute kidney injury(AKI) in rats.Methods:A total of 28 Wistar rats were randomly divided into five groups:(1) pseudo-operation control group,(2) ischemia-reperfusion model group, (3) Astragaloside group,(4) high-dose SHP group,and(5) low-dose SHP group.There were four rats in the pseudo-operation group and six rats in each of the other groups.The accepted ischemia-reperfusion model was established after a 7-day gavage intervention,and pathological changes and renal function were observed,using an enzyme-linked immunosorbent assay(ELISA) to detect interleukin 8(IL-8) and interferon gamma(IFN-γ) levels,as well as immunohistochemical staining to detect altered levels of TLR2 and TLR4 expression in renal tissue.Results:After 24 h,renal pathological damage and the expression levels of serum creatinine(Scr),IL-8, IFN-γ,TLR2,and TLR4 were significantly higher in the model group as compared with the pseudo-operation group(P0.05).In addition,at 24 h the above indicators decreased significantly in the Astragaloside group,high-dose SHP group and low-dose SHP group as compared with the ischemia-reperfusion model group(P0.05). TLR2 and TLR4 expression levels were significantly reduced in the SHP treatment and Astragaloside group as compared with the pseudo-operation group(P0.05).Further,the high-dose SHP group showed significantly less renal damage score and decreased levels of TLR expression than those of low-dose SHP group and Astragaloside group(all P0.05).Conclusion:SHP can alleviate the renal structural and functional damage caused by IRI-induced AKI in rats by reducing the damage of renal pathology,which may reduce inflammatory cytokine levels by downregulating the expression of TLRs in renal tissue in a dose-dependent manner.     

Clinical observation of treatment of hyperbilirubinemia in the newborn by integrated traditional chinese and western medicine

Objective: To find a method of treatment for correcting hyperbilirubinemia timely and effectively to prevent bilirubin induced cerebral damage in the newborn. Methods: The newborns with hyperbilirubinemia in the treated group were treated with conventional treatment plus Butyribacterial preparation (BBP) and Simo Decoction (SMD, 四磨饮) taken orally, and the effect was compared with that in control group A treated with conventional treatment only and that in control group B treated with conventional treatment plus BBP. Results: The mean daily decreasing rate of bilirubin in the treated group was 51.11±25.03 μmol/L, which was higher than that in control groups A (39.36±22.44 μmol/L) and B (43.24±24.18 μmol/L), respectively (P<0.01 and P<0.05). The bilirubin decreasing value on the first day and the speed of bilirubin decreasing (to 102.6 μmol/L) in the treated group were both higher than those in the control groups, P<0.01. Conclusion: The combined therapy of conventional treatment plus BBP and SMD could rapidly reduce the blood bilirubin level in the newborn with hyperbilirubinemia, and shorten the therapeutic course markedly, and the therapeutic effect is superior to that of the conventional treatment alone or that of the conventional treatment plus BBP only.     

蛤蟆油和蛤蟆油卵通过促进骨代谢治疗骨质疏松症

Objective

To evaluate the roles or effects of oviductus ranae (OR) or oviductus ranae eggs (ORE) in preventing and treating postmenopausal osteoporosis.

Methods

In vivo experiment: Sixty female adult Wistar rats were randomly divided into 5 groups of 12. To provide an osteoporosis model 4 groups of rats were ovariectomized (OVX), with the 5th being sham operated. Medication commenced 7 days after the operation and lasted continuously for 12 weeks. Sham operated and OVX groups were given equivalent volumes of 5% Tween-80. The other three groups intragastrically received conjugated estrogens (CE), OR or ORE of the corresponding doses. At the 12th week, serum estrogen, bone gla protein (BGP), serum calcium, phosphorus, and alkaline phosphatase (ALP) were assayed; bone mineral densities (BMD) were measured and bone scanning was conducted; uteri were weighed, and weight, volume and length of the femoral bones were determined; and cortical thickness of femoral heads and area of bone trabecula were measured by image analyzer. In vitro experiment: Eighty 10-month old SD rats, with equal numbers of males and females, were randomly divided into 8 groups. Osteoblasts were isolated from neonatal rat calvariae, and the cells were exposed to various concentrations of serum from OR and ORE groups to study the impact of these sera on osteoblastic proliferation, ALP activity and mineralization. Osteoclastic numbers were determined using tartrate resistant acid phosphatase (TRAP).

Results

In vivo experiment: The body weight of the four OVX groups increased significantly (P<0.01). Uterine weight of the CE group was the highest (P<0.01); Compared with the model group, estrogen level, BMD, bone scanning/bone imaging index weight of the femoral bones, cortical thickness of femoral heads in the OR and ORE groups increased significantly (P<0.05, P<0.01); femoral volume in the ORE group increased significantly (P<0.05); and the content of osteocalcin, phosphorus, and ALP in serum decreased significantly (P<0.05, P<0.01). In vitro experiment: Sera from OR and ORE groups had notable effects on the proliferation of osteoblasts (P<0.05 and P<0.01, repsectively) and stimulated the formation of calcium nodes (P<0.05, P<0.01), while the enhancement of ALP activity in osteoblasts was significant (P<0.05, P<0.01). The number of TRAP-positive cells was significantly reduced as well (P<0.01).

Conclusions

OR and its eggs could effectively suppress OVX-induced osteoporosis in rats, and increase bone turnover possibly by both an increase in osteoblastic activity and a decrease in osteoclastic activity. The present study provides evidence that OR and its eggs could be considered a complementary and alternative medicine for the treatment of postmenopausal osteoporosis.

尿毒清颗粒对体内及体外肾小管上皮细胞向间质细胞转化的抑制作用

Objective： To investigate the effect of the Uremic Clearance Granule （UCG, 尿毒清颗粒）, a Chinese patent medicine, on tubular epithelial-to-mesenchymal transition （EMT） in a unilateral ureteral obstruction （UUO） model in vivo and transforming growth factor （TGF）- 131 induced EMT of HK-2 cells in vitro. Methods： In vivo study, 50 Sprague Dawley rats were divided into three groups： a sham operation group （n=10）, a UUO group （n=20）, and a UUO with UCG treatment group （n=20）. The UCG was given at a dose of 4.5 g/kg body weight per day by gavage after surgery. In vitro study, HK-2 cells were cultured in 10% fetal bovine serum （FBS）, 10% healthy rat serum, 10% FBS and TGF-13 1 （10 ng/mL）, 10% healthy rat serum and TGF-13 1, or 10% rat serum containing the uremic clearance granule and TGF-13 1. The expression of the epithelial marker E-cadherin and the mesenchymal markers vimentin and e~-smooth muscle actin （ot-SMA） in kidney tissues and HK-2 cells were investigated by Western blot analysis and immunofluorescence staining. Results： The rats of the UUO group showed obvious tubulointerstitial fibrosis, compared with the sham operation group rats. Tubulointerstitial fibrosis score was reduced by 17.5%± 1.1% at day 7 and by 20.0%_＋ 1.2% at day 14 in the UCG-treated group, compared with the UUO group. The UCG could maintained expression of E-cadherin and suppressed expression of vimentin and α-SMA in kidney tissues of UUO rats at days 7 and 14, as determined by Western blot analysis and immunofluorescence staining. Rat serum containing the UCG partially inhibited TGF- β 1-induced fibroblast phenotype of HK-2 cells and maintained the epithelial morphology of HK-2 cells in vitro. This occurred partially through a reduction of vimentin expression and an increase of E-cadherin expression. Conclusion： These results suggest that the UCG prevents tubular EMT and may be a promising agent for treating tubulointerstitial fibrosis.     

柴芩承气汤对于重症急性胰腺炎患者基质金属蛋白酶-9的调节作用

Objective： To investigate the effect of Chaiqin Chengqi Decoction （柴芩承气汤, CQCQD） on regulating serum matrix metalloproteinase 9 （MMP-9） in patients with severe acute pancreatitis （SAP）. Methods： Thirty-five SAP patients hospitalized in West China Hospital from September 1, 2008 to February 28, 2009 were randomly assigned to two groups using a computer-derived random number sequence in a ratio of 1：1, treatment group （18 patients） and the placebo control group （17 patients）. The patients in the treatment group were administered with CQCQD by gastric parfusion （50 mL/2 h） and retention enema （200 mL/6 h） for 7 days. The two groups had similar baseline information. The clinical indicators, including the initial Balthazar＇s computed tomography （CT） score, acute physiology and chronic health evaluation I1 （APACHE II） scores on 1st, 3rd, 5th and 7th day, incidences and durations of complications and the serum C-reactive protein （CRP）, levels of MMP-9 on the 1st, 3rd, 5th and 7th day, were recorded and compared between the two groups. Resalts： The serum MMP-9, CRP and the APACHE I1 scores on the 3rd, 5th and 7th day in the treatment group were lower than those in the control group （P〈0.05）. The serum MMP-9 was positively correlated with the APACHE II score on the 1st day （r=0.430, P=0.01）. The durations of acute respiratory distress syndrome （5.4± 2.4 vs. 2.9± 1.3）, acute hepatitis （4.6± 0.8 vs. 1.9 ± 0.6） and acute heart failure （3.9 ± 1.6 vs. 1.3 ± 0.6, P〈0.05） in the control group were longer than those in the treatment group. Conclusion： CQCQD could decrease the serum MMP-9 to relieve the severity of clinical symptoms and prevent the development of multiple organ dysfunction syndrome in patients with SAP.     

Effect of unilateral posterior crossbite and unilateral cleft lip and palate on vertical mandibular asymmetry

Objective

Evaluate condylar, ramal, and condylar plus ramal vertical mandibular asymmetry in patients with unilateral posterior crossbite (UPCB) and in patients with unilateral cleft lip and palate (UCLP) compared with subjects having normal occlusion.

Design

This cross-sectional study evaluated panoramic radiographs of three groups of subjects: UPCB, 20 patients; UCLP, 20 patients; and normal occlusion sample, 20 subjects. All subjects were picked at random from Rey Juan Carlos University, Madrid, and all films were traced and measured manually by the same author.

Results

Kruskal–Wallis test revealed no statistically significant differences (P < 0.05) in condylar asymmetry index (CAI), ramal asymmetry index (RAI), and condylar plus ramal asymmetry index (C + RAI) among the three groups. The average CAI for group UPCB was 9.03 ± 7.65; 8.03 ± 6.89 for group UCLP; 6.93 ± 9.87 for normal group. Mean RAI for group UPCB was 2.53 ± 2.52; 2.61 ± 1.22 for group UCLP; 2.65 ± 1.90 for normal group.

Conclusions

Condylar asymmetry was observed in all three groups (UPCB, UCLP and normal occlusion) because condylar asymmetry indexes were higher in each group at the 3 % threshold. No statistically significant differences were found among the three study groups for any of the asymmetry indexes.     

Synergistic Protection of Danhong Injection (丹红注射液) and Ischemic Postconditioning on Myocardial Reperfusion Injury in Minipigs

Objective: To explore the synergistic protection of Danhong Injection (丹红注射液,DHI) and ischemic postconditioning on myocardial reperfusion injury in minipigs.Methods: Acute myocardial infarction model was made by balloon occlusion in left anterior descending coronary artery (LAD) of minipigs,and then postconditioning was simulated through inflation/deflation of the angioplasty balloon.Minipigs were divided into four groups: the sham operation group (SH group),the ischemia/reperfusion group (I/R group),the ischemic postconditioning group (POC group) and DHI combined with ischemic postconditioning group (PAD group,DHI 20 mL through ear vein),six in each group.After 24-h continuous observation,myocardial infarction size was assessed by triphenyltetrazolium staining (TTC).Morphological changes of ischemic myocardium were observed by light microscopy,and cardiomyocyte ultrastructure was studied with electron microscopy.The superoxide dismutase (SOD) and malondialdehyde (MDA) activity in heart homogenates were measured by a biochemical method.Results: The myocardial infarction size was smaller in the POC group than in the I/R group (0.26±0.02 vs.0.37±0.09,P0.05),and the PAD group (0.14±0.08) displayed a significantly reduced infarction size relative to the I/R group (P0.01) and POC group (P0.05).The damage of myocardial tissue was severe in the I/R group shown by light and electron microscopy: myocardial fibers disorder,sarcoplasmic dissolution,myofilament fracture,mitochondria swelling and even vacuolization formation and a large number of inflammatory cell infiltrations.Compared with the I/R group,reduction of reperfusion injury in the PAD group included more orderly arranged myocardial fibers,less infiltration of inflammatory cells and maintenance of mitochondrial integrity.Compared with the I/R group,the damage of myocardial tissue in the POC group was improved,but not as significant as that in the PAD group.SOD levels in the POC group and the PAD group were significantly higher than those in the I/R group (96.96±13.43,112.25±22.75 vs.76.32±10.63,P0.05),and MDA was significantly lower in the POC group and the PAD group compared to the I/R group (1.27±0.19,1.09±0.21 vs.1.47±0.16,P0.05).Conclusion: DHI and ischemic postconditioning show a synergistic cardioprotection on myocardial reperfusion injury in minipigs.

祛痹镇痛方对胶原蛋白诱导的关节炎大鼠滑液基因表达的作用

Objective: To investigate the effect of the Chinese medical formula Qubi Zhentong Recipe (祛痹镇痛方, QZR) on the synovial gene expression pro?le in collagen-induced arthritis (CIA) rats. Methods: Ten rats were randomly chosen from 60 rats as the control group, and the other 50 rats were used for the CIA models. The CIA model group was constructed by bovine injection of type Ⅱ collagen through the rats'' neck and tail. Twenty rats were randomly chosen from 34 successful CIA models and randomly assigned into two groups: the model group (n=10) and the QZR group (n=10). The QZR group was fed intragastrically with QZR 22.9 g/(kg?d) (10 times the clinical adult dose), and the CIA model group was given the same dose of normal saline. Both model and QZR groups were administered treatment once a day. Total RNA was collected from the knee joint synovium after 30 days. The change in gene expression pro?le was analyzed by a whole gene chip. Results: A total of 76 genes showed a difference in expression between CIA model group and the control group; 35 genes were down-regulated and 41 were up-regulated. A total of 67 genes showed a difference in expression between the model group and the QZR group; 48 genes were down-regulated and 19 were up-regulated. Conclusions: QZR may affect CIA by stimulating multiple genes and targets, which are related to oncogenes, apoptosis, metabolism, the immune system, ion channels, and transport proteins.     

Effects of different therapeutic methods and typical recipes of Chinese medicine on activation of c-Jun N-terminal Kinase in Kupffer cells of rats with fatty liver disease

<正>Objective:To observe the effects of different therapeutic methods and the recipes of Chinese medicine(CM) on the activation of c-Jun N-terminal kinase(JNK) in Kupffer cells of rats with fatty liver disease and to explore the mechanisms of these therapeutic methods.Methods:By using a random number table,98 rats were randomly divided into 7 groups:control group,model group,and 5 treatment groups,including soothing Liver(Gan) recipe group,invigorating Spleen(Pi) recipe group,dispelling dampness recipe group,promoting blood recipe group,and complex recipe group.Rats in the control group were fed with normal food and distilled water by gastric perfusion,while rats in the model group were fed with high-fat food and distilled spirits by gastric perfusion.Rats in the 5 treatment groups were fed with high-fat food and corresponding recipes by gastric perfusion.Twelve weeks later,all rats were sacrificed and liver tissues were stained for pathohistological observation.Kupffer cells were isolated from livers of rats to evaluate JNK and phospho-JNK expressions by Western blotting.Results:The grade of hepatic steatosis was higher in the model group than the control group(P0.05).Compared with the model group,the grade of fatty degeneration in soothing Liver recipe group and invigorating Spleen recipe group were significantly ameliorated(P0.05).Expressions of JNK and phospho-JNK in Kupffer cells were significantly higher in the model group than those in the control group(P0.05,P0.01).Compared with the model group,expressions of JNK in all treatment groups decreased,especially in invigorating Spleen recipe group and promoting blood recipe group(P0.05).Compared with the model group,expressions of phospho-JNK in all treatment groups declined significantly(P0.01),especially in soothing Live recipe group and invigorating Spleen recipe group. Conclusions:The high expressions of JNK and phospho-JNK in Kupffer cells might play an important role in the pathogenesis of fatty liver disease in rats.The recipes of CM,especially invigorating Spleen recipe and soothing Liver recipe,might protect liver against injury by reducing the total JNK protein content and inhibiting the activation of JNK protein in Kupffer cells of fatty liver model rats,which showed beneficial effects on fatty liver disease.
