Alterations in serotonin, transient receptor potential channels and protease-activated receptors in rats with irritable bowel syndrome attenuated by Shugan decoction

AIM:To determine the molecular mechanisms of Shugan decoction(SGD) in the regulation of colonic motility and visceral hyperalgesia(VHL) in irritable bowel syndrome(IBS).METHODS:The chemical compounds contained in SGD were measured by high-performance liquid chromatography.A rat model of IBS was induced by chronic water avoidance stress(WAS).The number of fecal pellets was counted after WAS and the pain pressure threshold was measured by colorectal distension.Morphological changes in colonic mucosa were detected by hematoxylin-eosin staining.The contents of tumor necrosis factor(TNF)-αin colonic tissue and calcitonin-gene-related peptide(CGRP)in serum were measured by ELISA.The protein expression of serotonin[5-hydroxytryptamide(5-HT)],serotonin transporter(SERT),chromogranin A(Cg A)and CGRP incolon tissue was measured by immunohistochemistry.RESULTS:SGD inhibited colonic motility dysfunction and VHL in rats with IBS.Blockers of transient receptor potential(TRP)vanilloid 1(TRPV1)(Ruthenium Red)and TRP ankyrin-1(TRPA1)(HC-030031)and activator of protease-activated receptor(PAR)4 increased the pain pressure threshold,whereas activators of PAR2and TRPV4 decreased the pain pressure threshold in rats with IBS.The effect of SGD on pain pressure threshold in these rats was abolished by activators of TRPV1(capsaicin),TRPV4(RN1747),TRPA1(Polygodial)and PAR2(AC55541).In addition,CGRP levels in serum and colonic tissue were both increased in these rats.TNF-αlevel in colonic tissue was also significantly upregulated.However,the levels of 5-HT,SERT and Cg A in colonic tissue were decreased.All these pathological changes in rats with IBS were attenuated by SGD.CONCLUSION:SGD alleviated VHL and attenuated colon motility in IBS,partly by regulating TRPV1,TRPV4,TRPA1,PAR2,5-HT,Cg A and SERT,and reducing CGRP and TNF-αlevel.

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.

Effect of Chaihu Shugan decoction on gastric smooth muscle cell apoptosis in rats with functional dyspepsia

Objective:To investigate the effect of Chaihu Shugan decoction(CSD)on gastric smooth muscle cells(GSMCs)apoptosis in rats with functional dyspepsia(FD).Methods:48Sprague-Dawley(SD)rats were randomly assigned into six groups:a normal control group,a model group,apositive control(domperidone)group and low-,middle-and high-dose CSD groups.A rat model of FD was established by constantly squeezing their tails.The rats were administered CSD(0.16g/mL,0.32g/mL,0.64g/mL)or domperidone(0.3 g/L)via intragastric gavage for four weeks.The gastric emptying rate was detected at 4 weeks post-administration.Apoptosis of GSMCs was determined by terminal deoxynucleotidyl transferase dUTP nick end labeling(TUNEL)staining and the mitochondrial morphology was observed by transmission electron microscopy.The expression of Bcl-2and Bax was measured by immunohistochemistry.Results:FD resulted in marked reduction of gastric emptying rate,severe gastric tissue damage and mitochondria injury,but were reversed by CSD treatment(P<0.05).The apoptosis-induced protein Bax was markedly down-regulated by CSD,whereas the expression of the anti-apoptotic Bcl-2 protein was notably increased(P<0.05).Furthermore,CSD could protect the FD rats against GSMCs apoptosis manifested by a decreased in TUNEL-positive cells(P<0.05).Conclusion:CSD could alleviate GSMCs apoptosis in FD rats,possibly by the modulation of Bcl-2 and Bax expression,and the suppression of mitochondria injury.

Comparative Study of the Effect of Shugan Shuru Granule (疏肝舒乳颗粒) on Pathology and p53 Gene Expression in Patients with Hyperplastic Disease of Breast

Objective: To study the effect of Shugan Shuru Granule (疏肝舒乳颗粒,SSG) on the p53 gene expression in patients with hyperplastic disease of breast (HDB) to indirectly explore the mechanism of SSG’s effect on HDB on the molecular pathological level. Methods: Sixty-six patients with HDB were allocated in the treated group and the control group,with the former treated with SSG and the latter not. All patients underwent breast operation and their diseased mammary tissues were cut out, sectioned, and observed under microscopy with HE staining and immunohistochemical staining, with ABC method adopted to estimate the degree of hyperplasia and p53 gene expression. The severity of HDB was classified into normal, mild, moderate and severe grades (marked as 0 to Ⅲ), according to the degree of hyperplasia in the mammary gland. Results: Hyperplasia in the control group mostly belonged to grade Ⅰ-Ⅲ before treatment, showing overgrowth of gland and proliferation of glandular epithelial cells, which were high columnar shaped, more stratified, with papillary or substantive dysplasia. While in the treated group, most belonged to grade 0-Ⅰ after SSG treatment, with proliferated gland and dysplasia recovered to normal or disappeared. The positive rate of p53 gene expression in the treated group was 9.09%, and in the control group 39.39%, comparison between the two groups showing significant difference (P<0.01), the intensity in the former was significantly weaker than that in the latter.Conclusion: SSG could not only inhibit the proliferation of mammary duct epithelia and lobuli, but also inhibit the over-expression of P53. Therefore, it could be regarded as an effective remedy for treatment of HDB and prevention of mammary cancer genesis.

Chaihu-Shugan-San exerts an antidepressive effect by downregulating miR-124 and releasing inhibition of the MAPK14 and Gria3 signaling pathways

Dysregulation of mi R-124 has been reported to be involved in the pathophysiology of depression. Chaihu-Shugan-San, a traditional Chinese medicine, has antidepressive activity; however, the underlying mechanisms remain unclear. In this study, to generate a rodent model of depression, rats were subjected to a combination of solitary confinement and chronic unpredictable mild stress for 28 days. Rats were intragastrically administered Chaihu-Shugan-San（2.835 m L/kg/d） for 4 weeks, once a day. Real-time reverse-transcription quantitative polymerase chain reaction, mi RNA microarray, western blot assay and transmission electron microscopy demonstrated that ChaihuShugan-San downregulated mi R-124 expression and upregulated the m RNA and protein levels of mitogen-activated protein kinase 14（MAPK14） and glutamate receptor subunit 3（Gria3）. Chaihu-Shugan-San also promoted synapse formation in the hippocampus. The open field test, sucrose consumption test and forced swimming test were used to assess depression-like behavior. After intragastric administration of Chaihu-Shugan-San, sucrose consumption increased, while the depressive behaviors were substantially reduced. Together, these findings suggest that Chaihu-Shugan-San exerts an antidepressant-like effect by downregulating mi R-124 expression and by releasing the inhibition of the MAPK14 and Gria3 signaling pathways.
