Analysis of fibronectin, fibronectin receptor and interleukin 1 in patients with cirrhosis treated by Yanggan Jieyu decoction

AIM To investigate the adjusting effects of the Yanggan Jieyu (YGJY, nourishing the liver and alleviate mental depression) decoction on the plasma concentration of fibronectin (FN), fibronectin receptor (FNR), tumor necrosis factor alpha (TNF α) and the activity of interleukin 1 (IL 1) in patients with cirrhosis. METHODS Thirty four cases of cirrhosis (in decompensation) were divided into YGJY decotion treated group and control group treated by routine method. FN, FNR and TNF α were measured with ELESA and expressed as mg/L (FN, FNR) and ng/L (TNF α), and IL 1 was measured by mice thymocyte proliferation using β scintillation counter and expressed as cpm. RESULTS In YGJY decoction treated group, before treatment, FN was 247 9±97 2, FNR 5 6±2 7, TNF α 83 9±7 1 and IL 1 was 2760 8±813 6, and after treatment. FN was 298 3±93 2 ( P <0 01), FNR 4 3±2 3 ( P <0 05, TNF α 93 6±12 0 ( P <0 05) and IL 1 was 1922 3±847 0 ( P <0 05). The FN and TNF α plasma level after treatment increased remarkably, while FNR and IL 1 decreased obviously. In the control group before treatment, FN was 248 8±101 9, FNR 5 5±1 9, TNF α 126 1±48 1 and IL 1 was 2540 6±603 2, and after treatment was 241 6±77 1 ( P >0 05), FNR 5 4±1 2 ( P >0 05), TNF α 100 6±15 5 ( P >0 05) and IL 1 was 2360 6±860 0 ( P >0 05), the plasma levels of FN, TNF α, FNR and IL 1 did not change signifiantly. CONCLUSION YGJY decoction could prevent the process of the hepatic fibrosis by readjusting the plasma levels of FN, FNR, TNF α and IL 1 mediating acivities in cirrhosis, which is of clinical significance.

Xiaoqinglong decoction reduces dendritic cell differentiation and regulates the Th1/Th2 balance in a mouse model of allergic asthma

Background:Xiaoqinglong decoction(XQLD)is a classic Chinese medicinal formula that is widely used to treat allergic asthma.Recently,the use of XQLD to treat allergic asthma has inspired research to determine its mechanism of action.Because dendritic cells(DCs)and the T helper 1(Th1)/Th2 cytokine balance play important roles in allergic asthma,the present work aimed to assess how these immune system components are affected by XQLD.Methods:Thirty-six female BALB/C mice were randomly divided into three groups:an ovalbumin-based allergic asthma model group,a XQLD treatment group,and a control group.Histology was performed with haematoxylin and eosin staining and immunohistochemical staining.Bronchoalveolar lavage fluid and blood were collected from the animals and used to analyze the composition of inflammatory cells and expression levels of the cytokines interleukin(IL)-5 and IL-13.The thymic stromal lymphopoietin(TSLP)protein expression was assessed by western blot analysis,and the Gata3 and Tbx21 mRNA levels were assessed by polymerase chain reaction.Results:Compared with the OVA group,the levels of TSLP expression,IL-5,IL-13,and immunoglobulin E in the XQLD group were lower(all P<.01).The level of IL-4-expressing cells(Th2 cells)was lower(P=.0013),and the percentage of IFN-g-expressing cells(Th1 cells)was higher in the XQLD group compared with those in the OVA group(P=.0065).In addition,XQLD increased the expression of Tbx21 mRNA and decreased the expression of Gata3 mRNA in the lungs compared with the OVA group(both P<.01).Conclusion:These findings suggest that XQLD may ameliorate the course of allergic asthma by regulating the Gata3/Tbx21 balance and inhibiting TSLP expression,changes which are indicative of an altered Th1/Th2 balance.Thus,the clinical effectiveness of XQLD in treating allergic asthma may be due to its regulation of Th1/Th2 balance.

Therapeutic effects of Lingguizhugan decoction in a rat model of high-fat diet-induced insulin resistance

BACKGROUND Lingguizhugan(LGZG)decoction is a widely used classic Chinese medicine formula that was recently shown to improve high-fat diet(HFD)-induced insulin resistance(IR)in animal studies.AIM To assess the therapeutic effect of LGZG decoction on HFD-induced IR and explore the potential underlying mechanism.METHODS To establish an IR rat model,a 12-wk HFD was administered,followed by a 4-wk treatment with LGZG.The determination of IR status was achieved through the use of biochemical tests and oral glucose tolerance tests.Using a targeted metabolomics platform to analyze changes in serum metabolites,quantitative real-time PCR(qRT-PCR)was used to assess the gene expression of the ribosomal protein S6 kinase beta 1(S6K1).RESULTS In IR rats,LGZG decreased body weight and indices of hepatic steatosis.It effectively controlled blood glucose and food intake while protecting islet cells.Metabolite analysis revealed significant differences between the HFD and HFDLGZG groups.LGZG intervention reduced branched-chain amino acid levels.Levels of IR-related metabolites such as tryptophan,alanine,taurine,and asparagine decreased significantly.IR may be linked to amino acids due to the contemporaneous increase in S6K1 expression,as shown by qRT-PCR.CONCLUSIONS Our study strongly suggests that LGZG decoction reduces HFD-induced IR.LGZG may activate S6K1 via metabolic pathways.These findings lay the groundwork for the potential of LGZG as an IR treatment.

Buyang Huanwu decoction up-regulates Notch1 gene expression in injured spinal cord

Expression of genes in the Notch signaling pathway is altered in the injured spinal cord, which indicates that Notch participates in repair after spinal cord injury. Buyang Huanwu decoction, a traditional Chinese herbal preparation, can promote the growth of nerve cells and nerve fibers; however, it is unclear whether Buyang Huanwu decoction affects the Notch signaling pathway in injured spinal cord. In this study, a rat model was established by injuring the T10 spinal cord. At 2 days after injury, rats were intragastrically administered 2 m L of 0.8 g/m L Buyang Huanwu decoction daily until sacrifice. Real-time reverse transcription polymerase chain reaction analysis demonstrated that at 7, 14 and 28 days after injury, the expression of Notch1 was increased in the Buyang Huanwu decoction group compared with controls. These findings confirm that Buyang Huanwu decoction can promote the expression of Notch1 in rats with incomplete spinal cord injury, and may indicate a mechanism to promote the repair of spinal cord injury.

Huangqin decoction alleviates lipid metabolism disorders and insulin resistance in nonalcoholic fatty liver disease by triggering Sirt1/NF-κB pathway

BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is a clinicopathological entity characterized by intrahepatic ectopic steatosis.As a consequence of increased consumption of high-calorie diet and adoption of a sedentary lifestyle,the incidence of NAFLD has surpassed that of viral hepatitis,making it the most common cause of chronic liver disease globally.Huangqin decoction(HQD),a Chinese medicinal formulation that has been used clinically for thousands of years,has beneficial outcomes in patients with liver diseases,including NAFLD.However,the role and mechanism of action of HQD in lipid metabolism disorders and insulin resistance in NAFLD remain poorly understood.AIM To evaluate the ameliorative effects of HQD in NAFLD,with a focus on lipid metabolism and insulin resistance,and to elucidate the underlying mechanism of action.METHODS High-fat diet-induced NAFLD rats and palmitic acid(PA)-stimulated HepG2 cells were used to investigate the effects of HQD and identify its potential mechanism of action.Phytochemicals in HQD were analyzed by highperformance liquid chromatography(HPLC)to identify the key components.RESULTS Ten primary chemical components of HQD were identified by HPLC analysis.In vivo,HQD effectively prevented rats from gaining body and liver weight,improved the liver index,ameliorated hepatic histological aberrations,decreased transaminase and lipid profile disorders,and reduced the levels of pro-inflammatory factors and insulin resistance.In vitro studies revealed that HQD effectively alleviated PA-induced lipid accumulation,inflammation,and insulin resistance in HepG2 cells.In-depth investigation revealed that HQD triggers Sirt1/NF-κB pathwaymodulated lipogenesis and inflammation,contributing to its beneficial actions,which was further corroborated by the addition of the Sirt1 antagonist EX-527 that compromised the favorable effects of HQD.CONCLUSION In summary,our study confirmed that HQD mitigates lipid metabolism disorders and insulin resistance in NAFLD by triggering the Sirt1/NF-κB pathway.

Objective:Ephedra asarum aconite decoction is used in the clinical treatment of allergic rhinitis.We investigated the effects of ephedra asarum aconite decoction on Th1/Th2 balance in two animal models of allergic rhinitis and in activated T cells in vitro.Methods:Animal models of simple and compound kidney yang deficiency types of allergic rhinitis were treated with ephedra asarum aconite decoction to observe the efficacy of this traditional Chinese medicine formula on allergic symptoms,serum cytokines,and tissue RNA levels.We also cultured and activated T cells from the mouse.After treatment with ephedra asarum aconite decoction,we tested the proliferation and differentiation of T cells.Results:Ephedra asarum aconite decoction relieved allergy symptoms in both types of animal models,and was more effective in the compound kidney yang deficiency model In addition to its anti-allergic efficacy,ephedra asarum aconite decoction significantly improved the health status of animals in the compound kidney yang deficiency groups,significantly made their bodyweight rising up,and significantly increased the T-bet mRNA/GATA-3 mRNA ratio.Moreover,ephedra asarum aconite decoction promoted the proliferation of activated T cells and inhibited the differentiation to Th2 cells in vitro.Conclusions:Ephedra asarum aconite decoction regulates the balance of Th1/Th2 to ameliorate allergic conditions.

Shugan-decoction relieves visceral hyperalgesia and reduces TRPV1 and SP colon expression

AIM:To evaluate the therapeutic effect of Shugan-decoction(SGD)on visceral hyperalgesia and colon gene expressions using a rat model.METHODS:Ninety-six adult male Wistar rats were randomized into six equal groups for assessment of SGD effects on psychological stress-induced changes using the classic water avoidance stress(WAS)test.Untreated model rats were exposed to chronic(1 h/d for 10 d consecutive)WAS conditions;experimental treatment model rats were administered with intragastric SGD at1 h before WAS on consecutive days 4-10(low-dose:0.1g/mL;mid-dose:0.2 g/mL;high-dose:0.4 g/mL);control treatment model rats were similarly administered with the irritable bowel syndrome drug,dicetel(0.0042g/mL);untreated normal control rats received no drug and were not subjected to the WAS test.At the end of the 10-d WAS testing period,a semi-quantitative measurement of visceral sensitivity was made by assessing the abdominal withdrawal reflex(AWR)to colorectal balloon-induced distension(at 5 mmHg increments)to determine the pain pressure threshold(PPT,evidenced by pain behavior).Subsequently,the animals were sacrificed and colonic tissues collected for assessment of changes in expressions of proteins related to visceral hypersensitivity(transient receptor potential vanilloid 1,TRPV1)and sustained visceral hyperalgesia(substance P,SP)by immunohistochemistry and real-time polymerase chain reaction.Inter-group differences were assessed by paired t test or repeated measures analysis of variance.RESULTS:The WAS test successfully induced visceral hypersensitivity,as evidenced by a significantly reduced AWR pressure in the untreated model group as compared to the untreated normal control group(190.4±3.48 mmHg vs 224.0±4.99 mmHg,P<0.001).SGD treatments at mid-dose and high-dose and the dicetel treatment significantly increased the WAS-reduced PPT(212.5±2.54,216.5±3.50 and 217.7±2.83 mmHg respectively,all P<0.001);however,the low-dose SGD treatment produced no significant effect on the WAS-reduced PPT(198.3±1.78 mmHg,P>0.05).These trends corresponded to the differential expressions observed for both TRPV1 protein(mid-dose:1.64±0.08 and high-dose:1.69±0.12 vs untreated model:3.65±0.32,P<0.001)and mRNA(0.44±0.16 and0.15±0.03 vs 1.39±0.15,P<0.001)and SP protein(0.99±0.20 and 1.03±0.23 vs 2.03±0.12,P<0.01)and mRNA(1.64±0.19 and 1.32±0.14 vs 2.60±0.33,P<0.05).These differential expressions of TRPV1 and SP related to mid-and high-dose SGD treatments were statistically similar to the changes induced by dicetel treatment.No signs of overt damage to the rat system were observed for any of the SGD dosages.CONCLUSION:Shugan-decoction can reduce chronic stress-induced visceral hypersensitivity in rats,and the regulatory mechanism may involve mediating the expressions of TRPV1 and SP in colon tissues.

Cerebroprotective effect of Huanglian Jiedu decoction on amyloid protein precursor/presenilin-1 double transgenic mice

Huanglian Jiedu decoction （HLJDD） has been shown to improve cerebral blood flow, and reduce lipid peroxidation damage to the brain and its energy metabolism. The present study was designed to observe the cerebroprotective effect of HL.JDD on an Alzheimer＇s disease rodent model, presenilin-1/amyloid protein precursor double transgenic mice. HLJDD reduced serum interleukin-6 and interleukin-113 levels, decreased [3-amyloid precursor protein gene and senile plaque expression, resisted oxidation, and reduced free radical-induced injury, thereby improving the learning and memory of these mice. Moreover, HLJDD at 433 mg/kg per day exhibited better effects compared with that at 865 or 216 mg/kg per day, and donepezil hydrochloride at 30 mg/kg per day. Thus, these results suggest that HLJDD may have protective effects against Alzheimer＇s disease.

Effects of Siwei Yuganzi decoction on LXRα and CYP7A1 in hyperlipidemic rats

Background:Hyperlipidemia(HLP)is a disorder in which lipids in the blood are disturbed due to abnormal lipid metabolism.Statins and fibrates lipid-regulating drugs prevent the generation of lipids and improves HLP,thereby reducing the likelihood of developing cardiovascular and cerebrovascular diseases.However,their adverse reactions and side effects limit a wide range of clinical applications.Tibetan medicine compound preparation Siwei Yuganzi decoction(SYD)is an adaptation of a classical prescription of the Tibetan medicine Sanguo decoction,that has been proved to have the effect of improving lipid metabolism;however,its possible mechanism remains unknown.Methods:Sixty specific-pathogen free grade Sprague Dawley rats were randomly divided into the blank control group,the HLP group,the Chinese patent medicine Xuezhikang positive control group,and the treatment groups with Tibetan SYD high-,middle-,and low-dosages respectively.Ten rats were assigned to each group.Every rat in these groups was fed with a high-fat emulsion to establish the hyperlipidemic animal model,except for those in the blank control group.Then the rats in the blank control and HLP groups were fed with 0.9%normal saline,those in Xuezhikang group were fed with Xuezhikang suspension at the dose of 0.11 g/kg/d,and those in SYD groups were fed with the SYD suspension at the dosage of 16.2 g/kg/d(high dosage),10.8 g/kg/d(middle dosage),and 5.4 g/kg/d(low dosage),respectively.After 8 weeks,the levels of serum total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C)were detected by the ELISA.The mRNA and protein expression levels of liver X receptorα(LXRα)and cholesterol 7α-hydroxylase 1(CYP7A1)were detected using RT-PCR,western blotting,and immunohistochemistry.Results:The serum levels of TC,TG,and LDL-C in the HLP group were higher than those in the blank control group(P<0.05),whereas the serum levels of HDL-C and the expression levels of both LXRαand CYP7A1 mRNA and proteins in the liver in the HLP group were lower than those in the control group(P<0.05).After the treatment of the Xuezhikang and SYD,the serum levels of TG,TC,and LDL-C significantly decreased(P<0.05),whereas the serum levels of HDL-C and the expression levels of both LXRαand CYP7A1 mRNA and proteins in the liver significantly increased compared with those in the HLP group(P<0.05).Furthermore,The serum levels of TC,TG,and LDL-C in the SYD group at high dosage were lower(P<0.05),the serum level of HDL-C was higher,and the expression levels of both LXRαand CYP7A1 mRNA and proteins in the liver tissue were higher than those in the Xuezhikang group(P<0.05).Conclusion:SYD can improve the serum levels of TC,TG,and LDL-C in the hyperlipidemic animal model via increasing the expression of both LXRαand CYP7A1 mRNA and proteins in the liver tissue.
