Exploring the mechanism of Yishen Daluo decoction in the treatment of multiple sclerosis based on network pharmacology and in vitro experiments

Objective:To explore the mechanism and related active components of Yishen Daluo decoction(YSDLD)in treating multiple sclerosis(MS).Methods:Targets of YSDLD were collected through the TCMSP,Chemistry,and TCMID databases.The MS targets were collected through OMIM,DrugBank,Gencards,TTD,and Pharmgkb databases.We built“componentetarget”network diagrams and proteineprotein interaction(PPI)diagrams and performed topological analysis.The targets were subjected to GO and KEGG enrichment analysis.Molecular docking verification was conducted on selected targets and molecules.Finally,in vitro experiments were con-ducted.BV2 cells were induced by lipopolysaccharide for model establishment.CCK8 experiment was conducted to explore the effect of YSDLD and RT-qPCR technology was used to explore the expression of key targets.Results:There were 184 active components in YSDLD and 898 targets of its action.There were 940 MS targets,and 215 targets were shared by YSDLD and MS.According to the“componentetarget”diagram,the top five key components included quercetin,kaempferol,beta-sitosterol,stigmasterol,and nar-ingenin.IL-6,IL-1 b,TNF-α,AKT1,and VEGFA were the important targets identified by PPI network to-pology analysis.A total of 564 functions were identified by GO enrichment analysis(P<0.01),mainly involving inflammatory response,hypoxia response,plasma membrane,neuronal cell body,protein phosphatase binding,and cytokine activity.KEGG enrichment analysis enriched 98 pathways(P<.01).YSDLD at the concentration of 20 m g/mL had no effect on BV2 cells.RT-qPCR indicated that YSDLD at the concentrations of 15 m g/mL and 20 m g/mL alleviated LPS-induced inflammatory injury and lowered the content of inflammatory factors(P<0.05).Conclusion:In this paper,the network pharmacology and in vitro experiments were used to explore the potential mechanism of YSDLD in treating MS.The research provides a good basis for the development of YSDLD and drugs for MS in future.

Clinical Thoughts and Cases of Jianpi Yishen Sechang Decoction Combined with Acupuncture in the Treatment of Functional Diarrhea

Functional diarrhea(FDr)accounts for a relatively high proportion of digestive diseases.It is an infection that is not accompanied by abdominal pain and shows negative results in laboratory tests for bacteria and viruses.The main symptoms are persistent or recurrent discharge of watery and soft stools.The course of the disease is prolonged and recurring,and the treatment cost is higher and greatly affects the patient’s daily life.The incidence rate has a gradual increase in the trend.Its pathogenesis is complex where Western medicine is mostly used in symptomatic drug treatment.The treatment can be fast-acting and effective in relieving diarrhea.However,the long-term use of Western medicine poses a high risk in terms of side effects and a high chance of recurring upon stopping medication.At the same time,some diarrhea patients show the existence of drug-resistant strains of bacteria,and the overall efficacy of the drug is limited.Chinese medicine is mild and able to provide excellent treatment of diarrhea.With its lower price and cost,most families can afford it.Fengliang Tian,director of traditional Chinese medicine,implemented the“needle and medicine”method,which combines medicine and acupuncture,involving the usage of Jianpi Yishen Sechang Decoction and acupuncture in the treatment of functional diarrhea.The method has a low price,fewer side effects,is easy to accept,and can significantly reduce the recurrence rate with high efficacy.The study would like to share the clinical thinking and cases as follows to provide ideas and methods for the treatment of functional diarrhea by traditional Chinese medicine.

Yishen Huoxue decoction(益肾活血方) attenuates unilateral ureteric obstruction-induced renal fibrosis and hypoxia-induced reactive oxygen species generation via adenosine monophosphate-activated protein kinase/peroxisome proliferator-activated receptor coa

OBJECTIVE:To investigate the effeicacy of Yishen Huoxue decoction(YSHX)on renal fibrosis induced by unilateral ureteric obstruction(UUO),and on reactive oxygen species(ROS)homeostasis in human umbilical vein endothelial cells(HUVECs).METHODS:Forty male mice were randomly divided into six groups,sham group,UUO group,UUO+resveratrol(RSV)(15 mg/kg)group,UUO+YSHX20 mg/kg group(UUO+YSHX-L),UUO+YSHX 40 mg/kg group(UUO+YSHX-M),UUO+YSHX 80 mg/kg group(UUO+YSHX-H).Western blotting was used to measure protein expression levels.Reverse transcription-quantitative polymerase chain reaction was used to measure the m RNA expression.Immunohistochemistry was used to examine the histopathological changes of kidney tissue sample.Cell apoptosis was measured by Annexin V/PI staining.Cell viability was measured using CCK-8/WST-8 assay.RESULTS:YSHX treatment reducedα-SMA and Col-4 expressions,and increased CD31 and VE-cadherin expressions in UUO model mice.In vitro,YSHX increased cell viability and decreased apoptosis of HUVECs under hypoxic conditions.YSHX inhibited ROS generation by activating adenosine monophosphate-activated protein kinase(AMPK)/peroxisome proliferator-activated receptor coactivator-1α(PGC-1α)/silent mating-type information regulation2 homolog 3(Sirt3)signaling.CONCLUSION:YSHX treatment reduced 109 KJ UUO-induced renal injury and fibrosis.Furthermore,YSHX treatment attenuated hypoxia-induced oxidative stress by regulating AMPK/PGC-1α/Sirt3 signaling.

Clinical Observation of the Treatment of Myelodysplastic Syndrome Mainly with Qinghuang Powder(青黄散)

Objective： To observe the clinical effectiveness of Qinghuang Powder （青黄散, QHP） combined with Bupi Yishen Decoction （补脾益肾汤 BPYS） in treating myelodysplastic syndrome （MDS）, and its relationship with France, America, and Britain （FAB） type, international prognosis scaling system （IPSS） risk, and chromosome karyotype. Methods： There were 124 MDS patients subjected to the tests. By FAB typing, 91 patients were typed as refractory anemia （RA） type and 33 as refractory anemia with excess of blasts （RAEB） type; by IPSS scale, 21 were sorted to low risk, 77 to moderate risk I, 20 to moderate risk ]], and 6 to high risk; 78 of them had normal chromosome and 46 with abnormal chromosome, including 26 of trisomy 8. All patients were treated with QHP＋BPYS, and the changes of peripheral blood figure and bone marrow were observed. Results： After treatment, the general effective rate was 72.58% （90/124）, which in the patients of RA type was 80.22% （73/91） and in RAEB type 51.52% （17/33）. The former was better than that in the later （P〈0.01）. For the analysis in the patients of different IPSS risk degrees, the effective rate was 95.24% （20/21） in the low- risk group, 72.73% （56/77） in moderate risk I, 65.00% （13/20） in moderate-risk 11, and 16.67% （1/6） in high- risk group. Those in the first two groups were superior to that in the latter two （P〈0.01）. The effective rate was 79.49% （61/78） in the patients with normal chromosome and was 60.87% （28/46） in the patients with abnormal chromosome, showing a significant difference between them. While in the patients of trisomy 8, it was 73.08% （19/26）, which was parallel to that in the patients with normal chromosome. Conclusion： The effectiveness of QHP＋BPYS comprehensive therapy for MDS is unquestionably good, and it is markedly correlated with the FAB type and IPSS risk degree of the disease, as well as the normality of chromosome in the patient.
