Objective To evaluate the role of microglia in paraventricular nucleus (PVN) in sus-ceptibility to depression in rats with chronic visceral pain. Methods Ninety-six pathogen-free healthy male Sprague-Dawley rats, aged 8 days, were divided into 6 groups (n= 16 each) using a random number table: sham operation group (S group), chronic visceral pain group (CHVP group), sham operation plus colorectal distension group (S+C group), chronic visceral pain plus colorectal distension group (CHVP+C group), chronic visceral pain plus phosphate buffer solution plus colorectal distension group (CHVP+P+C group) and chronic visceral pain plus minocycline plus colorectal distension group (CHVP+M+C group). Colorectal distension was not performed in S group. In CHVP group, chronic visceral pain was induced by performing colorectal distension twice daily on postnatal days 8, 10, and 12. Phosphate buffer solution 0. 5μl was injected into PVN by stereotaxic method at 8th week after birth in CHVP+P+C group, and 2％ mi-nocycline 0. 5 μl was injected into PVN at 8th week after birth in CHVP+M+C group. Eight rats in each group were selected 2 h later for measurement of visceral pain threshold. In S+C, CHVP+C, CHVP+P+C and CHVP+M+C groups, colorectal distension was performed for 2 times, open field test and sucrose preference test were then performed, the rats were sacrificed and PVN was removed for determination of micro-glial activation by immunofluorescence. Results The pain threshold was significantly decreased in CHVP, CHVP+C, CHVP+P+C and CHVP+M+C groups as compared with S and S+C groups (P<0. 05). The pain threshold was significantly increased in CHVP+M+C group when compared with CHVP +P +C group (P<0. 05). Compared with S, CHVP and S+C groups, the total locomotor distance, the number of rea-ring and sucrose consumption were significantly reduced, and the proportion of activated microglia in PVN was increased in CHVP+C, CHVP+P+C and CHVP+M+C groups (P<0. 05). Compared with CHVP+P+C group, the total locomotor distance, the number of rearing and sucrose consumption were significantly in-creased, and the proportion of activated microglia in PVN was decreased in CHVP+M+C group (P<0. 05). Conclusion Microglia in PVN is involved in regulation of susceptibility to depression in rats with chronic visceral pain.

Objective·To investigate the effects of sennoside A(SA)on the formation of atherosclerotic plaque and the expression of 5-hydroxytryptamine(5-HT)and its receptor in mice with diabetes mellitus type 2(T2DM).Methods·Twelve mice with knocked-out apolipoprotein E gene were randomly divided into two groups,namely the model group and the model+SA group,with six mice in each group.Six C57BL/6J mice with the same genetic background were used as the control group.The control group was fed with normal diet,and the model group and the model+SA group were given intraperitoneal injection of streptozotocin(30 mg/kg)daily on the basis of high-fat diet to establish a model of T2DM.The model+SA group was given SA daily by gavage for 8 weeks,and the control group and the model group were given equal volume of distillation-distillation H2O by gavage.The body weight,fasting blood glucose(FBG)and 2-h postprandial blood glucose of mice were compared before and after modeling and treatment.The area of aortic plaque was observed by oil red O staining and hematoxylin-eosin(H-E)staining,and the level of 5-HT in serum and thoracic aorta was measured by ELISA kit.Western blotting was used to detect the expression of 5-hydroxytryptamine receptor 2B(HTR2B)and serotonin transporter(SERT)in thoracic aorta of mice.Results·Compared with the control group,the body weight,FBG and 2-h postprandial blood glucose in the model group increased,and glucose metabolism was disordered.The expression of HTR2B and SERT protein in thoracic aorta increased,while the concentration of 5-HT in thoracic aorta decreased.The serum 5-HT concentration increased(all P<0.05).After treatment with SA,compared with the model group,the body weight of the model+SA group decreased,and FBG and 2-h postprandial blood glucose were significantly improved.The area of aortic plaque and the expression of HTR2B and SERT protein in thoracic aorta significantly decreased,while the concentration of 5-HT increased.The serum 5-HT concentration decreased(all P<0.05).Conclusion·SA can reduce atherosclerotic plaque area in T2DM mice,which may be related to lowering blood glucose and inhibiting the expression of 5-HT and its receptor.

Objective To investigate the mechanism of inhibitory effect of mollugin on hepatocellular carcinoma based on the ferroptosis pathway.Methods HepG2 cells were cultured in vitro and divided into control group,mollugin low-(10 μmol/L),medium-(20 μmol/L),and high-dosage(40 μmol/L)groups based on the inhibitory concentration of 50%.The cell viability was detected by CCK-8 method,cytotoxicity was detected by LDH kit,and the ability of cell colony formation was observed by clone formation assay,the contents of GSH,MDA,ROS,SOD,superoxide,lipid peroxide and MMP were detected,the protein expression of ferroptosis suppressor protein 1(FSP1),GTP cyclohydrolase 1(GCH1),dihydroorotate dehydrogenase(DHODH)and glutathione peroxidase 4(GPX4)were detected by Western blot,the mRNA expression of FSP1,DHODH,GCH1 and GPX4 were detected using RT-qPCR.The effect of mollugin on cell viability and GSH,MDA contents of hepatocellular carcinoma cells were observed under overexpression and silencing of GPX4 by mollugin.Results The medium-and high-dose of mollugin could reduce the number of clone formation in HepG2 cells,decrease the GSH content and SOD activity of cells,increase the content of MDA,superoxide,lipid peroxides and ROS,and decreased MMP(P<0.001).The intervention of mollugin had no significant effect on the expressions of FSP1,GCH1,DHODH protein and mRNA in HepG2 cells,but could decrease the expression of GPX4 protein and mRNA(P<0.001).Overexpression and silencing experiments confirmed that GPX4 was the core target for the regulation of ferroptosis by mollugin.Conclusion Mollugin mainly exerts its anti-liver cancer effect by regulating GPX4 mediated ferroptosis.
