Research progress of traditional Chinese medicine compound in the treatment of gout based on intestinal flora

Because of the continuous improvement of the quality of life,the population of gout patients is also increasing,which seriously affects the quality of life of patients.Traditional Chinese medicine compound has a long history and remarkable clinical effect in treating gout patients,and has been widely used.Intestinal flora and its metabolites are the focus of current research,which can promote intestinal mucosal barrier,improve immunity and improve metabolism.The regulation of intestinal flora can reduce serum uric acid and inhibit inflammation to fight gouty arthritis.Moreover,the mechanism of intestinal flora is related to the spleen in Chinese medicine theory.Therefore,this study discusses the research mechanism and clinical application of traditional Chinese medicine compound in treating gout by regulating intestinal flora,and provides theoretical basis for the clinical application of traditional Chinese medicine and the expansion of new dosage forms.

Effect of Chinese herbal compound on liver fibrosis in rabbits with schistosomiasis by B-ultrasound

Objective: To explore the value of B-ultrasound on the evaluation of the effects of traditional Chinese medicine compound of Radix astragali , Salvia miltiorrhiza and Angelica sinensis , and TCM + praziquantel on liver fibrosis in rabbits with schistosomiasis. Methods: The hepatic fibrosis model in rabbits with schistosomiasis was established. The experimental animals (24 rabbits) were randomly divided into four groups (group A, B, C and D, n =6). Group A (control group) was only treated by praziquantel; Group B was treated by mixture of Radix astragali and Salvia miltiorrhiza + praziquantel; Group C was treated by mixture of Radix astragali and Angelica sinensis + praziquantel; Group D was treated by mixture of Radix astragali, Salvia miltiorrhiza and Angelica sinensis + praziquantel. Then B-ultrasonogram was used to evaluate the effects. Results: Each group showed certain curative effect on liver fibrosis in rabbits with schistosomiasis. The efficacy of group B, C and D was better than group A, and that of group D was the best. The differences in long diameter, thickness diameter, transverse diameter and portal vein inner diameter of liver before and after treatment were statistically significant ( P <0.05). The liver function indexes and liver fibrosis indexes were significantly improved after treatment ( P <0.05). Conclusions: The mixture of Radix astragali, Salvia miltiorrhiza and Angelica sinensis combined with Western medicine treatment can obviously improve the efficacy on liver fibrosis of schistosomiasis.

Therapeutic Efficacy of Chinese Herbal Compound Preparation on Viral Diseases in Poultry

[Objective] To develop a new antiviral agent with high and long efficacy, wide spectrum, low toxicity and low cost from traditional Chinese herbal medicine and their compound. [ Method] The ＂Quxie＂ （ i. e. eliminating pathogenic factors） drugs including Hedyotis diffusa and Loni- cera japonica and ＂Fuzheng＂ （ i. e. strengthening body resistance） drugs including Radix astragali and Glycyrrhiza uralensis were taken to form an antiviral herbal compound preparation. Taking the astragalus polysaccharide monomer as control, the experiment was constructed by using the agent to treat some naturally occurring viral diseases, including Newcastle disease （ND）, infectious bursal disease （IBD）, duck viral hepatitis （DVH）, avian influenza （Al） H9 subtype and avian swollen head syndrome. [Ressult] The effective rates of the agent for treatment of the above- mentioned diseases were 87%, 87%, 69%, 100% and 100%, respectively, which were higher than that of astragalus polysaccharide monomer. The cure rates for these diseases were 33%, 37%, 13%, 69% and 75%, respectively, which were significantly higher than that of astragalus polysacchadde monomer （ P 〈 0.01 ）. The rates of poor therapeutic efficacy were 15%, 21%, 24%, 6% and 7%, respectively, which were significantly lower than that of astragalus polysaccharide monomer （P 〈 0.01 ）. [ Condusion] The Chinese herbal compound preparation shows good therapeutic effects on some avian viral diseases, which can decrease mortality rate and improve production performance of poultry more greatly than astragalus polysaccharide monomer.

[ Conclusion ] Chinese herbal compound could improve the hematopoietic function of myclosuppressivc mice induced by cyclophosphamide and its effect was better than Astragalus polysaccharide. 20 g/kg Chinese herbal compound reacted fast and the reaction of 10 g/kg Chinese herbal compound was slow ,but its efficacy was lasting.

Efficacy of Chinese herbal compound GAPT for the treatment of Alzheimer’s disease during mouse/rat studies:A systematic review and meta-analysis

Objective:To evaluate the efficacy of the Chinese herbal compound GAPT for the treatment of Alzheimer’s disease(AD)and to provide current evidence for potential treatment mechanisms.Methods:A comprehensive search of PubMed,Embase,Web of Science,SinoMed,China Network Knowledge Infrastructure,Wanfang Data,and Chinese Scientific Journals Database was performed to identify GAPT mouse/rat studies published from inception to July 2019.The outcomes extracted were Morris water maze results and molecular biological quantifications.Results:A total of 19 studies were included in this analysis.The analysis indicated that GAPT was able to significantly improve learning and memory abilities compared with model mice/rats,as assessed by Morris water maze,and showed similar efficacy as donepezil.Subgroup analyses showed that low,medium,and high doses resulted in no obvious dose-dependent effects.Additionally,the GAPT group had significantly reduced expression levels of amyloid-beta peptide,presenilin 1,phosphorylated tau,acetylcholinesterase,and glycogen synthase kinase-3b,but increased expression levels of Shank1,and protein phosphatase-2A,and improved synapses structures compared with the model group,and subgroup analyses showed the medium dose of GAPT was superior to the low and high doses.Conclusions:Based on the pooled analysis,GAPT improved the learning and memory abilities and regulated the expression levels of related proteins during the progression of AD in mouse/rat studies.Notably,the medium dose of GAPT exhibited better performance than the other two doses,providing experimental evidence for further applications of GAPT during clinical practice.

A PRELIMINARY STUDY OF THE EFFECTS OF CHEMOTHERAPEUTICAGENTS IN COMBINATION WITH CHINESE HERBAL COMPOUNDS AS IMMUNOMODULATORS IN MOUSE S_(180)

The effect of the Chinese herbal compound (CHC) on solid sarcoma 180 (S180) in Swiss mice was studied either alone or in combination with 5-fluorouracil (5FU), cyclophosphamide (CYT) or mitomycin C (MMC). The preliminary results indicated that combination treatment seemed to possess better antitumor activity than chemotherapy alone. The treatment with CHC alone however had neither an obvious antitumor effect in tumor bearing mice nor toxicity in normal mice. These results show that CHC may stimulate organs of the immune system such as the spleen to be im-munomodulators and enhance the antitumor activity of some chemotherapeutic agents.

Therapeutic potential of natural compounds from Chinese medicine in acute and subacute phases of ischemic stroke

Stroke is one of the leading causes of death and disability in adults worldwide,resulting in huge social and financial burdens.Extracts from herbs,especially those used in Chinese medicine,have emerged as new pharmaceuticals for stroke treatment.Here we review the evidence from preclinical studies investigating neuroprotective properties of Chinese medicinal compounds through their application in acute and subacute phases of ischemic stroke,and highlight potential mechanisms underlying their therapeutic effects.It is noteworthy that many herbal compounds have been shown to target multiple mechanisms and in combinations may exert synergistic effects on signaling pathways,thereby attenuating multiple aspects of ischemic pathology.We conclude the paper with a general discussion of the prospects for novel natural compound-based regimens against stroke.
