Comprehensive regulation of traditional Chinese medicine on proliferation and differentiation of neural stem cells

Since the diccovery of neural stem cells(NSCs)in the embryonic and adult mammalian central nerous system,it provided novel ideas forneurogenesis as the potential of proliferation and differentiation of NSCs.One of the ways to promote the clinical application of neural stem cells(NSCs)is searching effective methods which regulate the proliferation and differentiation.This is also a problem urgently to be solved in medical field.Plenty of earlier studies have shown that traditional chinese medicine can promote the proliferation and differentiation of NSCs by regulating the related signaling pathway in vivo and in vitro.The reports of Chinese and foreign literatures on regulating the proliferation and differentiation of neural stem cells in recent ten years and their target and signaling pathways is analyzed in this review.The traditional chinese medicine regulate proliferation and differentiation of NSCs by the signaling pathways of Notch,PI3K/Akt,Wnt/β-catenin,and GFs.And,those signaling pathways have cross-talk in the regulation progress.Moreover,some traditional Chinese medicine,such as astragalus,has a variety of active ingredients to regulate proliferation and differentiation of NSCs through different signaling pathways.However,to accelerate the clinical application of neural stem cells,the studies aboutthe proliferation and differentiation of NSCs and Chinese medicine should be further deepened,the mechanism of multiple targets and the comprehensive regulation function of traditional Chinese medicine should be clarified.

Studies on the Degranulation of RBL-2H3 Cells Induced by Traditional Chinese Medicine Injections

Aims: To study RBL-2H3 cell degranulation phenomena induced by some TCMIs through cell morphological and ultra-structural observation, released enzyme activity and establish RBL-2H3 cell degranulation test indicated by β- hexosaminidase activity as a method to evaluate TCMIs at nonclinical stage. Methods: RBL-2H3 cells were used to study the degranulation by co-culture with positive control C48/80 and some TCMIs through morphological and ultra-structure observation, β-hexosaminidase activity detection. RBL-2H3 cell degranulation test was established to detect β-hexosaminidase activity caused by 17 kinds of TCMIs and their ingredients. The cytotoxicity effect of some TCMIs on both RBL 2H3 and BRL cells was measured by CCK-8 assay. Results: Toluidine blue staining and ultra-structure of electronic microscope observation of treated RBL-2H3 cells showed degranulation morphologically. Detection of β-hexosaminidase activity in the supernatant of treated cells showed some TCMIs had elevated enzyme release rates. Further analysis of the ingredients and compound in Tanreqing Injection and Shengmai Injection showed Scutellaria baicalensis Georgi in Tanreqing Injection, Red ginseng and Fructus Schisandrae Chinensis in Shengmai Injection were responsible to the degranulation of RBL-2H3 cells. Osmotic pressures and pH influenced RBL-2H3 degranulation. High Osmotic pressure of Tanreqing Injection and low pH of chlorogenic acid at 2.5 and 5.0 mmol/L congcentration might be responsible to high β-hexosaminidase activity. Most of the TCMIs inducing degranulation had cytotoxicity effect for both RBL-2H3 and BRL cells, but some TCMIs inducing degranulation had no cytotoxicity effect. Conclusion: Some TCMIs can induce degranulation of RBL-2H3 cells;RBL-2H3 cell degranulation test can be used in non-clinical stage to detect the risk causing anaphylactoid reactions. Osmotic pressures and pH influenced RBL-2H3 degranulation, and they should be measured before testing. The mechanism of degranulation caused by some TCMIs is cytotoxic, and some are non-cytotoxic and may be through exicytosis.

Nature products of traditional Chinese medicine provide new ideas in γδT cells for tumor immunotherapy

Due to the unique features of innate immune cells, the role of γδT cells in tumor immunity has gradually attracted more and more attention. Previous studies have found that γδT cells play a dual role in tumor immunology: tumor-promoting and tumor-controlling.The anti-tumor therapy of γδT cells has made remarkable success in clinical application. Especially in recent years, researchers have provided some novel effective ways such as γδT cells exosomes and adoptive chimeric antigen receptor-γδT cells immunotherapy. However, some problems remain to be solved, such as low expansion rate, poor targeting, and tumor microenvironment limiting the effectiveness of γδT immunotherapy. Traditional Chinese medicine is expected to play a positive role in the body immune-enhancing function, promoting the proliferation and activation of γδT cells, and inducing the differentiation ofγδT cells. In this review, we summarize the recent research progress and urgent problems of γδT cells in anti-tumor immunotherapy. Moreover, some new strategies of γδT cells for tumor immunotherapy were proposed.

Research on the influence of traditional Chinese medicine therapy on the intestinal flora in obese patients

In recent years, the prevalence of obesity has been increasing year by year, leading to a rise in serious complications. The pathogenesis of obesity is complicated in which the intestinal flora plays an important role. Intestinal micro ecology is composed of large and complex intestinal flora that participate in important physiological functions such as metabolism, energy conversion, maintaining intestinal mucosal defense function, and promoting immune system development and maturation and other important physiological functions;furthermore, they are influenced by the host’s genetic background, diet, and other factors. Therefore, intestinal microflora has potential as a new field of drug therapy. At present, it is found that traditional Chinese medicine therapy may prevent and treat obesity by interfering with the intestinal flora, which is expected to become one of the main treatment methods for obese patients. However, its mechanism of action remains unclear. The balance of intestinal flora can be adjusted by acupuncture, massage, and acupoint application. By analyzing the mechanism of obesity caused by intestinal micro ecology and the impact of obesity on the host’s intestinal micro ecological environment, this paper discusses the influence of oral Chinese medicine, acupuncture, massage, acupoint sticking, and other traditional Chinese medicine therapies on the intestinal microflora in obese patients and provides a scientific basis for its clinical application.

Gut microbiota contributes to the distinction between two traditional Chinese medicine syndromes of ulcerative colitis

BACKGROUND Ulcerative colitis(UC)is considered to be closely associated with alteration of intestinal microorganisms.According to the traditional Chinese medicine(TCM)theory,UC can be divided into two disease syndromes called Pi-Xu-Shi-Yun(PXSY)and Da-Chang-Shi-Re(DCSR).The relationships among gut microbiota,TCM syndromes,and UC pathogenesis have not been well investigated.AIM To investigate the role of gut microbiota in UC and the distinction of microbiota dysbiosis between PXSY and DCSR syndromes.METHODS From May 2015 to February 2016,UC patients presenting to LongHua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study.Fresh stool specimens of UC patients with PXSY or DCSR were collected.The feces of the control group came from the health examination population of Longhua Hospital.The composition of gut bacterial communities in stool samples was determined by the pyrosequencing of 16S ribosomal RNA.The high-throughput sequencing reads were processed with QIIME,and biological functions were predicted using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States.RESULTS The composition of gut bacterial communities in 93 stool samples(30 healthy controls,32 patients with PXSY syndrome,and 31 patients with DCSR syndrome)was determined by the pyrosequencing of 16S ribosomal RNA.Beta diversity showed that the composition of the microbiota was different among the three groups.At the family level,Porphyromonadaceae,Rikeneliaceae,and Lachnospiraceae significantly decreased while Enterococcus,Streptococcus,and other potential pathogens significantly increased in UC patients compared to healthy subjects.At the genus level,Parabacteroides,Dorea,and Ruminococcus decreased while Faeca-libacterium showed increased abundance in UC compared to healthy controls.Five differential taxa were identified between PXSY and DCSR syndromes.At the genus level,a significantly increased abundance of Streptococcus was observed in DCSR patients,while Lachnoclostridium increased in PXSY patients.The differential functional pathways of the gut microbiome between the PXSY and DCSR groups mainly included lipid metabolism,immunity,and the metabolism of polypeptides.CONCLUSION Our study suggests that the gut microbiota contributes to the distinction between the two TCM syndromes of UC.

Advances in traditional Chinese medicine for liver disease therapy in 2021

Liver diseases and their co-morbidities represent a major public health problem.Owing to its progressive pathogenesis and lack of effective treatment,liver disease has become one of the most important causes of death worldwide.Traditional Chinese medicine(TCM)has potential advantages in the prevention and treatment of liver diseases,including high safety,remarkable curative effects,and low toxicity and side effects.In 2021,TCM extracts and their derivatives,TCM compounds,and ethnic medicines showed good efficacy in the treatment of liver diseases.The main mechanisms and representative drugs of TCM can be summarized by the use of amygdalin,dicoumarol,quercetin,and ancient ephedrine decoction to treat hepatitis by inhibiting viral replication,as well as the use of Gentianae Radix,lupeol,Zornia diphylla(L.)Pers.,and Chinese patent medicine Liuwei Wuling tablet to alleviate acute liver injury by improving oxidative stress and inflammatory responses in the body.In the treatment of alcoholic liver disease and metabolic-associated fatty liver disease,the mechanism of TCM is the inhibition of oxidative stress,improving metabolism,regulating intestinal microflora,and enhancing intestinal barrier function.The representative TCM for alcoholic liver disease includes astragaloside,puerarin,patchouli alcohol,and Mori Fructus polysaccharide,while those for metabolic-associated fatty liver disease include saikosaponin,dehydroabietic acid,hesperetin,berberine,and Panax Notoginseng saponins.Additionally,germacrone,forsythin,geniposide,and protocatechuic acid can inhibit the activation or migration of stellate cells and improve liver fibrosis.Toosendanin,paeoniflorin,chrysin,and the classical prescription Huanglian decoction can significantly inhibit the proliferation of liver cancer cells and promote their apoptosis for the treatment of hepatocellular carcinoma.The activation of the farnesol X receptor pathway can improve bile metabolism in the liver,thus,significantly alleviating cholestatic liver disease.Its representative drugs include the TCM extracts pterostilbene and arbutin.In this review,we summarize the advances made in research on TCM used in the treatment of liver diseases in 2021,providing a reference for further development of TCM for the prevention and treatment of liver diseases.

Celastrol activates caspase-3/GSDME-dependent pyroptosis in tumor cells by inducing endoplasmic reticulum stress Author links open overlay panel

Objective To investigate the pyroptosis-inducing effects of celastrol on tumor cells and to explore the potential mechanisms involved,specifically focusing on the role of the caspase-3/gasdermin E(GSDME)signaling pathway and the impact of endoplasmic reticulum(ER)stress and autophagy.Methods Necrostatin-1(Nec-1),lactate dehydrogenase release(LDH)assay,and Hoechst/propidium iodide(PI)double staining were employed to validate the mode of cell death.Western blot was used to detect the cleavage of GSDME and the expression of light chain 3(LC3)and BIP.Results Celastrol induced cell swelling with large bubbles,which is consistent with the pyroptotic phenotype.Moreover,treatment with celastrol induced GSDME cleavage,indicating the activation of GSDME-mediated pyroptosis.GSDME knockout via CRISPR/Cas9 blocked the pyroptotic morphology of celastrol in HeLa cells.In addition,cleavage of GSDME was attenuated by a specific caspase-3 inhibitor in celastrol-treated cells,suggesting that GSDME activation was induced by caspase-3.Mechanistically,celastrol induced endoplasmic reticulum(ER)stress and autophagy in HeLa cells,and other ER stress inducers produced effects consistent with those of celastrol.Conclusion These findings suggest that celastrol triggers caspase-3/GSDME-dependent pyroptosis via activation of ER stress,which may shed light on the potential antitumor clinical applications of celastrol.

Experimental Study of the Anti-human Papilloma Virus Mechanisms by a Traditional Chinese Medicine “Keyouling”

To investigate the anti-human papilloma virus (HPV) effect of the external liniment of traditional Chinese medicine “Keyouling”, the efficacy of this drug acting upon the proliferation and growth of the normal epidermis cells of rabbits′ penis prepuce in different concentrations was observed. An experimental model of pathology of histocytes infected with HPV in vitro was established by using the human HPV infected prepuce epidermis cells as virus carrier to infect the sub-cultured epidermis cells of rabbits′ penis prepuce. The direct killing effect and the blocking effect of infections of epidermis cells in rabbits′ penis prepuce induced by HPV with different concentrations of “Keyouling” were determined by 3 kinds of culture methods: (1) the infected epidermis cells of rabbits′ penis prepuce were challenged by co-culture with HPV suspension and with culture medium containing drug; (2) the co-culture with epidermis cells of rabbits′ penis prepuce and HPV suspension was challenged with drug; (3) co-culture with culture medium containing drug and epidermis cells of rabbits′ penis prepuce was challenged with HPV suspension. It was found that “Keyouling” had little effect on the proliferation and growth of the normal epidermis cells of rabbits′ penis prepuce, but it had direct killing effect on HPV, and blocked effectively the infection of the epidermis cells of rabbits′ penis prepuce by HPV. It concludes that “Keyouling” has significant killing effect to HPV, but not normal histocytes in vitro , indicating that it is safe for clinical use. Its blocking effect on the HPV infection of rabbits′ penis prepuce epidermis cells suggested “Keyouling” may be clinically used to prevent the development of tumors or to inhibit the further progression or metastasis of tumors.

How do Chinese medicines that tonify the kidney inhibit dopaminergic neuron apoptosis?

Wistar rats were intragastrical y perfused with Chinese medicines used for tonifying the kidney. These included 0.180 g/mL of Herba Epimedi （Epimedium）, Semen Cuscutae （Dodder Seed）, or Herba Cistanches （Desertliving Cistanche）, 0.04 mg/mL monoamine oxidase-B inhibitor selegiline, or distil ed water for 14 consecutive days to prepare drug-containing serum or blank serum. MES23.5 cells in the logarithmic phase were cultured in media supplemented with 15%drug-containing serum for 24 hours, fol owed by incubation in culture solution containing 100μmol/L H2O2 for 3 hours. 3-（4,5-Dimethylthiazol-2-yl）-2,5-diphenyltetrazolium bromide （MTT） and flow tometry results showed that al drug-containing serums improved the survival rate of H 2 O 2-injured MES23.5 cells, inhibited pro-apoptotic FasL and caspase-3 expression, promoted anti-apoptotic Bcl-2 expression. However, drug-containing serums had little influence on Fas expression in H 2 O 2-injured MES23.5 cells. Enzyme-linked immunosorbent assay results showed that serum containing Herba Cistanches or Herba Epimedi increased the expression of nerve growth factor, brain-derived neurotrophic factor, and glial cellline-derived neurotrophic factor in injured MES23.5 cells;serum containing Semen Cuscutae only increased brain-derived neurotrophic factor expres-sion; while expression of the above neurotrophic factors remained the same in cells treated with serum containing selegiline. These findings indicate that Chinese medicines used to tonify the kid-ney can protect nerve cells by regulating the expression of apoptosis-related factors and neuro-trophic factors in MES23.5 cells.
