ABSTRACT
Objective To observe the effects ofXiangsha Liujunzi Decoction (XSLJZ) on levels and mRNA of IL-6, IL-10 and protein expression of HSP70 of gastric mucosa in chronic atrophic gastritis (CAG) rats with spleen-stomach deficiency; To discuss its mechanism.Methods Rats were divided into 2 groups through random number table: normal group and model group. The model of CAG rat with spleen-stomach deficiency type was induced by synthetic methods. After successful modeling, rats were divided into model group, positive control group, XSLJZ high-, medium-, low-dose group. Rats in normal and model group received distilled water 10 mL/(kg?d) for gavage; XSLJZ high-, medium-, low-dose group received XSLJZ 24, 12, 6 g/(kg?d), respectively; positive control group received mycin 0.30 g/(kg?d) for gavage for 120 consecutive days. Generally living conditions, levels and mRNA of IL-6, IL-10 and protein expression of HSP70 in gastric mucosa tissue were detected by protein immunoblotting.Results Compared with the normal group, generally living conditions of rats in the model group were poor; mRNA and the content of IL-6 increased significantly, and mRNA and the content of IL-10 decreased significantly (P<0.05,P<0.01); mRNA and protein expression of HSP70 in gastric tissues was much lower than that of normal group (P<0.05,P<0.01). Compared with model group, generally living conditions of rats in the XSLJZ high-dose groups were improved significantly; mRNA and the content of IL-6 decreased significantly, and mRNA and the content of IL-10 increased significantly (P<0.05); XSLJZ high-, medium-dose groups mRNA and protein expression of HSP70 in gastric tissues increased significantly(P<0.05).Conclusion XSLJZ has protective effects on gastric mucosa of CAG rats with spleen-stomach deficiency.
ABSTRACT
The article reviewed the situation of warming kidney and strengthen spleen treatment for ulcerative colitis (UC) in recent 15 years from three aspects: Yang deficiency in spleen and kidney syndrome is one of the most important syndromes in UC; common prescriptions, medicine and efficacy of warming kidney and strengthening spleen treatment for treating UC; the mechanism of the treatment for UC is related to immunity enhancement, inhibition of gastrointestinal smooth muscle, promoting gastrointestinal function, antibiosis, improving plant nerve function, and release of enzymes. It also proposed the problems about warming kidney and strengthening spleen treatment for UC, and prospect for relevant problems.
ABSTRACT
Objective To study effects ofXiangsha Liujunzi Decoction (XSLJZ) on gastric emptying function, pepsin activity and expression of HIF-1α gene and protein of gastric mucosa in chronic atrophic gastritis (CAG) of rats with deficiency of spleen and stomach.Methods Rats were randomly divided into normal group and model group. The models of CAG rats with deficiency of spleen and stomach type were induced by synthetic methods. After the modeling, models rats were divided into model group, positive control group and XSLJZ high-, medium-, and low-dose groups. Normal group and model group were given 10 mL/kg distilled water every day for gavage; XSLJZ high-, medium-, and low-dose groups were given 24, 12, and 6 g/kg XSLJZ Decoction for gavage; positive control group was given 0.30 g/kg Vatacoenayme for gavage, for successive 120 d. Gastric emptying function and pepsin activity were detected, and HIF-1α gene and protein expression in gastric mucosa were detected by RT-qPCR and IHC. Results Compared with the normal group, the gastric emptying function and pepsin activity in the model group were much lower (P<0.01); expressions of HIF-1α gene and protein in gastric tissues was much higher (P<0.01). Compared with model group, XSLJZ could increase the gastric emptying function and pepsin activity significantly (P<0.05), and decrease expressions of HIF-1α gene and protein (P<0.05).Conclusion XSLJZ has functions of improving the gastric emptying function, promoting pepsin activity, and reducing expressions of HIF-1α gene and protein.
ABSTRACT
Objective To observe the dynamic changes of ghrelin of spleen-qi-deficiency rats and the intervention effects ofSijunzi Decoction.Methods Experimental rats were randomly divided into normal control group, model group andSijunzi Decoction group. Except for normal control group, spleen-qi-deficiency model was copied through the two-factor methods of breaking qi by bitter cold and swimming exhausted. Meanwhile,Sijunzi Decoction group was given 20 g/(kg?d)Sijunzi Decoction intervention. The activities of GAS, MTL, SS and VIP at different time points (14, 21, 28 d) in intestine and serum were detected by ELISA and RIA. At the same time the intervention effect of Sijunzi Decoction was studied.Results Compared with normal control group, GAS and MTL in intestine and serum of model rats decreased, while SS and VIP increased (P<0.05,P<0.01). Compared with model group, GAS and MTL in intestine and serum of rats in theSijunzi Decoction group increased, while SS and VIP decreased (P<0.05,P<0.01).Conclusion Ghrelin in intestine and serum of spleen-qi-deficiency rats shows dynamic coincidental changes.Sijunzi Decoction can treat spleen qi deficiency by regulating the activities of rat ghrelin.
ABSTRACT
Objective To investigate the effect of Yiqi Jianpi herb on content of NPY, VIP and expression of Mapk14 mRNA of rats with spleen-qi deficiency. Methods Rats were randomly divided into normal groups, model group (observed on 7 d, 14 d and 21 d), treatment group of Yiqi Jianpi herb, 10 rats in each group. The spleen-qi deficient model rats were made by rhubarb, exhaustive and hungry method, and treatment group was treated with Sijunzi decoction (20 g/kg) for 21 d, then the content of NPY, VIP in serum and small intestine were evaluated with radioimmunoassay, and expression of Mapk14 mRNA in small intestine tissue was evaluated with real time fluorescent quantitative PCR. Results In model group, content of NPY was much lower than that of normal group (P<0.05), content of VIP and relative expression of Mapk14 mRNA in small intestine tissue were much higher than that of normal group (P<0.05), the difference was obvious in 21 d group. Compared with model 21 d group, content of NPY was increased (P<0.05), content of VIP and relative expression of Mapk14 mRNA in small intestine tissue were decreased (P<0.05) in treatment group. Conclusion Yiqi Jianpi herb has functions of adjusting NPY, VIP secretion and inhibiting abnormal expression of Mapk14 mRNA.
