Duzhong Jiangu Granule in the treatment of primary osteoarthritis(POA)model of postmenopausal kidney deficiency type in Hartley female guinea pigs after ovariectomy,and the correlation between gene expression of bone marrow tissue,cartilage tissue,and knee osteoarthritis.Methods:383-months-old Hartley female guinea pigs after one week of adaptive feeding were weighed about 400 g±20 g,numbered,and sorted by ear tag.Six of them were selected as normal groups by looking up random number tables.The remainder were removed from the bilateral ovaries to construct the postmenopausal kidney deficiency model,and castrated guinea pigs were used to construct the postmenopausal kidney deficiency POA model.After the modeling cycle,a guinea pig from the blank group and a guinea pig from the model group were sacrificed and the right knee was observed.The model was established and the experiments continued.There were five guinea pigs in the blank group,and the remaining model guinea pigs were randomly divided into model control group,high-dose group of compound Duzhong Jiangu granules,middle-dose group of compound Duzhong Jiangu granules,low-dose group of compound Duzhong Jiangu granules and design group,with 5 guinea pigs in each group.Blanks and model groups were given a cellulose sodium solution by gavage.The guinea pigs were sacrificed after 30 days of intragastric administration.The left knee cartilage and bone marrow of the blank group,model group,middle dose group,and high dose group of compound Duzhong Jiangu granule were collected and applied to transcriptome sequencing,and the sequencing data were analyzed,including differential gene expression analysis,functional enrichment analysis of database established by Gene Ontology federation(GO)and Kyoto Encyclopedia of Gene and Genome(KEGG)pathway enrichment analysis.The complete specimens of the right knee joint were collected,and the morphological changes of the cartilage of the right knee joint in each group were observed by saffron rapid green staining,and the subchondral bone was quantitatively analyzed by Micro CT so that the expression of TRAF6,MIP-1βand IL-1βprotein in NF-kappa B signaling pathway was detected by Western Blot technique(WB).Results:The results of Safranin Fast Green staining showed that Compound Duzhong Jiangu Granules could effectively reduce the degree of morphological damage of articular cartilage in guinea pigs with the POA model.According to the analysis results of the subchondral bone structure under Micro CT,Compound Duzhong Jiangu Granules can improve the bone condition of the POA model,thus delaying the process of degenerative changes of the knee joint.From the results of transcriptome analysis,Compound Duzhong Jiangu Granules can inhibit the expression of related genes in POA model guinea pigs.According to the results of Wester Bolt verification,Compound Duzhong Jiangu Granules can effectively improve knee osteoarthritis.Conclusions:The effect of Compound Duzhong Jiangu Granules on OA is obvious,and its mechanism may be related to the expression of genes GZMK,Jchain,igkc,IGHV3-74,IGHV3-11,IGHV4-1,CCL5,and IGKV1–39.

Biomechanical analysis of optic nerve injury treated by compound light granules and ciliary neurotrophic factor

In this study, rabbit models of optic nerve injury were reproduced by the clamp method. After modeling, rabbit models were given one injection of 50 ng recombinant human ciliary neurotrophic factor into the vitreous body and/or intragastric injection of 4 g/kg compound light granules containing Radix Angelicae Sinensis and Raidix Paeoniae Alba at 4 days after modeling, once per day for 30 consecutive days. After administration, the animals were sacrificed and the intraorbital optic nerve was harvested. Hematoxylin-eosin staining revealed that the injured optic nerve was thinner and optic nerve fibers were irregular. After treatment with recombinant human ciliary neurotrophic factor, the arrangement of optic nerve fibers was disordered but they were not markedly thinner. After treatment with compound light granules, the arrangement of optic nerve fibers was slightly disordered and their structure was intact. After combined treatment with recombinant human ciliary neurotrophic factor and compound light granules, the arrangement of optic nerve fibers was slightly disordered and the degree of injury was less than after either treatment alone. Results of tensile mechanical testing of the optic nerve showed that the tensile elastic limit strain, elastic limit stress, maximum stress and maximum strain of the injured optic nerve were significantly lower than the normal optic nerve. After treatment with recombinant human ciliary neurotrophic factor and/or compound light granules, the tensile elastic limit strain, elastic limit stress, maximum stress and maximum strain of the injured optic nerve were significantly increased, especially after the combined treatment. These experimental findings indicate that compound light granules and ciliary neurotrophic factor can alleviate optic nerve injury at the histological and biochemical levels, and the combined treatment is more effective than either treatment alone.

Epigastric pain syndrome: What can traditional Chinese medicine do? A randomized controlled trial of Biling Weitong Granules

BACKGROUND Recent research suggests that although prokinetic agents,acid suppressors,and radical treatment for Helicobacter pylori infection may be effective in patients with functional dyspepsia(FD),a large proportion of patients still fail to respond to these treatments or may suffer from severe adverse reactions.Many traditional Chinese medicinal herbs can regulate the status of the entire body and have special advantages in the treatment of functional diseases.The present study was designed to verify the efficacy of Biling Weitong Granules(BLWTG),a traditional Chinese medicinal herbal compound formula,in alleviating epigastric pain syndrome(EPS)in FD patients,in an attempt to provide an effective prescription for the clinical treatment of this disease.AIM To evaluate the clinical efficacy and safety of BLWTG in treating EPS in patients with FD.METHODS In this multicenter,stratified,randomized,double-blind,placebo-controlled,parallel group clinical trial,eligible patients were randomized into the BLWTG and placebo groups who were treated for 6 wk.Efficacy indicators including the severity and frequency of EPS and the time to pain resolution and safety indicators including adverse events were observed and compared.RESULTS The baseline demographic data and clinical characteristics,such as epigastric pain symptoms,pain intensity,and frequency of attacks,were matched between the two groups before randomization.After 6 wk of treatment and after the center effect was eliminated,the epigastric pain was significantly improved in 28.33%and 85.59%of the patients in the placebo and BLWTG groups,respectively(P<0.05).At 6 wk,the resolution rate of epigastric pain was 15%and 69.49%in the placebo and BLWTG groups,respectively(P<0.05).The differences of total FD clinical score between these two groups were significant(P<0.05)at 2,4,and 6 wk(P<0.05).The scores of each item and the total score in the Functional Digestive Disorders Quality of Life Questionnaire showed significant differences between the two groups at 6 wk after both the center and interaction effects were eliminated(P<0.05).There was no significant difference in the incidence of adverse events between the two groups,and no serious adverse event was noted during the observation.CONCLUSION Compared with placebo,BLWTG markedly improved EPS in FD patients without causing serious adverse reactions.

Pharmacological evaluation and mechanistic study of compound Xishu Granule in hepatocellular carcinoma

Objective:In this study,we used HepG2 human hepatocellular carcinoma cells to study the effects of Compound Xishu Granule(CXG)on cell proliferation,apoptosis,and the cell cycle in vitro.We also used a xenograft tumor model to study the anti-tumor effects of CXG and related mechanisms in vivo.Methods:The effect of CXG on cell viability was measured using Cell Counting Kit-8 and a colony formation assay.The effect of CXG on apoptosis and the cell cycle was analyzed using flow cytometry.The in vivo anti-tumor effect of CXG was assessed by measuring the volume change in xenograft tumors after drug administration.The CXG anti-tumor mechanism was studied using western blotting assay to detect cell cycle and apoptotic associated proteins.Results:CXG suppressed HepG2 cell proliferation in a time-and dose-dependent manner in vitro.Colony formation experiments showed that CXG administration for 24 h significantly reduced HepG2 cell formations(P<.01).Flow cytometric analysis showed that CXG treatment for 48 h promoted apoptosis and blocked HepG2 cells in the G2/M phase.Western blotting results showed that Bax was significantly upregulated and Bcl-2 was down-regulated in graft tumor tissues and HepG2 cells after CXG administration,which increased the Bax/Bcl-2 ratio.PLK1,CDC25 C,CDK1,and Cyclin B1 expression were upregulated.CXG had a good inhibitory effect on graft tumor growth in vivo.Conclusion:CXG has good anti-tumor effects in vitro and in vivo.In vitro,CXG promoted HepG2 cell apoptosis and induced G2/M phase arrest.In vivo,CXG significantly inhibited graft tumor growth.The CXG mechanism in treating hepatocellular carcinoma may be that CXG can induce abnormal apoptotic and cell cycle associated protein expression,leading to mitotic catastrophe and apoptosis.
