ABSTRACT
OBJECTIVE To study the immunomodulatory effect of Guipi pills on D-galactose（D-gal）-induced aging mice. METHODS The immune-related targets and related pathways for Guipi pills to exert immune effects were screened by network pharmacology and verified through pharmacodynamic experiments. Totally 105 male ICR mice were randomly divided into blank control （CON） group， model control （MOD） group， positive control （POS） group， Guipi pills low-dose （GD） group and Guipi pills high-dose （GG） group. Except for the CON group， other groups were subcutaneously injected with 400 mg/kg D-gal to induce the aging model； CON group and MOD group were given distilled water， POS group was given 300 mg/kg pidotimod oral solution intragastrically， GD group and GG group were given Guipi pills 300， 600 mg/kg intragastrically， once a day， for 8 weeks. After medication， the serum and spleen were collected， and the contents of interleukin 2 （IL-2）， IL-4， IL-6 and tumor necrosis factor α （TNF-α）， and the contents of immunoglobulin G （IgG）， IgM and IgA were detected. The spleen index was calculated and the histopathological changes in the spleen were observed. The activities of superoxide dismutase （SOD）， glutathione peroxidase （GSH- Px） and malondialdehyde （MDA）， and the content of 8-hydroxy-2 deoxyguanosine （8-OHdG） in spleen were detected； the expression of TNF/phosphoinositide-3-kinase-threonine protein kinase （PI3k-Akt）-related proteins in spleen was detected except for POS group. RESULTS The results of network pharmacology showed that TNF， IL-6 and Akt1 were core targets. The results of pharmacodynamic study showed that compared with MOD group， the contents of IL-2， IL-4， IgG， IgM and IgA were increased significantly in Guipi pills groups， while the contents of TNF-α and IL-6 were decreased significantly； the spleen index was increased significantly （P＜0.05 or P＜0.01）. The phenomenon of diffuse proliferation of lymphocytes was improved， the spleen cells were closely arranged， and the line between the white pulp and red pulp was clear. The activities of SOD and GSH-Px in spleen were increased significantly， while the activity of MDA， the content of 8-OHdG， and the protein expressions of TNF-α， PI3K and p-Akt were decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Guipi pills can regulate the immune function of D-gal-induced aging mice， which is related to regulating the TNF/PI3k-Akt pathway， thereby reducing oxidative stress damage in spleen tissue of mice， and regulating protein expressions of TNF-α， PI3K and p-Akt.
ABSTRACT
Objective To evaluate the efficacy and safety of levothyroxine sodium combined with Guipi pills in the treatment of hypothyroidism . Methods A total of 114 cases from August 2013 to November 2015 in Lanxi Traditional Chinese Medicine Hospital with hypothyroidism were selected and randomly divided into control group and experiment group, 57 cases in each group.The patients in the both groups were given conventional treatment and symptomatic treatment.Patients in the control group were given levothyroxine sodium tablets 25 μg orally once a day, two weeks after continuous treatment according to the patient’s condition to 50μg.Patients in the experiment group were given levothyroxine sodium tablets 25μg orally once a day combined with Guipi pills 1.2g, three times a day.Two groups of patients a cycle of 28days, a total of 6 cycles of treatment.The clinical efficacy, thyroid hormone, lipid metabolic indexes and adverse drug reactions were compared between two groups.Results After treatment, the total effective rate of the control group was 78.95%, significantly lower than 92.98% of experimental group (P <0.05).The level of serum TSH, TC and TG were significantly decreased in two groups after treatment, and the experimental group was significantly lower than the control group(P<0.05); the levels of FT3 and FT4 were significantly increased, and the experimental group was significantly higher than the control group ( P <0.05 ).The incidence of adverse reactions was 10.53% in the control group and 5.26% in the experimental group, the difference was not statistically significant. Conclusion Levothyroxine sodium combined with Guipi pills in the treatment of hypothyrosis was effective with high safety.
ABSTRACT
OBJECTIVE: To study the pharmacokinetic parameter and the relative bioavailability of ferulic acid in ordinary Guipi pills and ultramicro Guipi pills in rabbit.METHODS: HPLC-MS/MS was used to identify the concentration of ferulic acid in the blood sample.RESULTS: Plasma concentration of ferulic acid in ordinary pills was different from that in ultramicro pills.The main pharmacokinetic parameters of ferulic acid in ordinary pills vs.that in ultramicro pills were as follows:t1/2a:(17.59?2.57) min vs.(23.51?4.49) min;t1/2?:(300.91?38.74) min vs.(167.17?45.66) min;tmax: (9.61?1.69) min vs.(12.33?2.27) min;Cmax:(58.92?8.42) ng?mL-1 vs.(112.35?31.29) ng?mL-1;AUC: (5 851.67?895.49) ng?min-1?mL-1 vs.(8 586.13?1 497.62) ng?min-1?mL-1.There were significant difference in Cmax and AUC between ordinary pills and ultramicro pills.CONCLUSION: The application of super fine crushing technique in the preparation of Guipi pills could improve the bioavailability of Guipi pills.
ABSTRACT
AIM: To establish the method for quality control of Guipi Pills(concentrated pill) (Radix Codonopsis,Rhizoma Atractylodis macrocephalae,Radix Astragali,Radix et Rhizoma Glycyrrhizae,etc).and a quantitative method of determining astragaloside IV. METHODS: Radix Codonopsis,Radix Angelicae Sinensis,Radix et Rhizoma Glycyrrhizae and Radix Aucklandiae in the pill were identified by TLC.Astragaloside IV in the pill was determined by HPLC-ELSD. RESULTS: For astragaloside IV,the linear range was within 25.4-508.3 ?g and the average recovery was 99.1%,r=0.999 7 with RSD of 0.8%. CONCLUSION: The method is simple,reliable,accurate,practical.It can be used in the quality control of Gui Pipills(concentrated pills).
