The mechanism,safety and application of berberine in promoting bone regeneration / 中国组织工程研究

BACKGROUND:Berberine has the potential to induce osteogenic differentiation of various mesenchymal stem cells under normal conditions and special conditions such as high glucose,infection and inflammation.It is a natural small molecule drug that can induce bone formation in seed cells instead of growth factors,and has great application prospect in bone tissue engineering. OBJECTIVE:To review and summarize the research progress in the osteogenic mechanism and efficacy of berberine,especially its osteogenic potential under high glucose,infection and inflammation conditions,and its biological safety,so as to provide theoretical basis for its development and application in bone tissue engineering. METHODS:PubMed,WanFang,and CNKI were searched for relevant literature using the keywords of"berberine,bone defects,bone repair,bone regeneration,osteoinductive,osteoporosis,osteoblast,osteoclast,bone tissue engineering,bone,high glucose,diabetes,inflam*,infect*"in English and Chinese,respectively.A total of 105 literatures were selected for review. RESULTS AND CONCLUSION:Berberine can be used to treat multiple diseases including bone diseases,and it has the ability to promote bone regeneration.This article systematically reviews the mechanism of berberine on bone regeneration and in vivo and in vitro studies.Studies have shown that it can play a role in bone repair by promoting osteogenesis,inhibiting osteoclast formation and activity,and preventing osteoporosis.It shows excellent osteogenic differentiation potential mainly via Wnt/β-catenin,PI3K/AKT,EGFR/MEK/p38MAPK,cAMP/PKA/CREB,ERK and other signaling pathways.Berberine can also relieve the inhibition of osteogenic differentiation caused by high glucose,infection and inflammation,which provides more possibilities for the treatment of bone defects in patients with diabetes or infection and inflammation in the bone defect site.Berberine also has the advantages of low toxicity,low price,easy access(currently it can be synthesized),which is a relatively ideal bone induction potential drug.In recent years,the application of berberine in the treatment of bone defect tends to be localized,mainly through the combination with bone tissue engineering technology to improve bioavailability,and has shown good bone repair effect and excellent biological safety in animal experiments.In addition,preclinical experiments have shown splendid bone regeneration potential in the conditions of diabetes,local infection and inflammation.In the future,more studies are needed to fully reveal the osteogenic mechanism and biological safety of berberine,and seek the most suitable controlled release loading system to make artificial bone replacement materials with good mechanical strength,efficacy and biological safety.

Screening the effective components in treating dampness stagnancy due to spleen deficiency syndrome and elucidating the potential mechanism of Poria water extract / 中国天然药物

Poria is an important medicine for inducing diuresis to drain dampness from the middle energizer. However, the specific effective components and the potential mechanism of Poria remain largely unknown. To identify the effective components and the mechanism of Poria water extract (PWE) to treat dampness stagnancy due to spleen deficiency syndrome (DSSD), a rat model of DSSD was established through weight-loaded forced swimming, intragastric ice-water stimulation, humid living environment, and alternate-day fasting for 21 days. After 14 days of treatment with PWE, the results indicated that PWE increased fecal moisture percentage, urine output, D-xylose level and weight; amylase, albumin, and total protein levels; and the swimming time of rats with DSSD to different extents. Eleven highly related components were screened out using the spectrum-effect relationship and LC-MS. Mechanistic studies revealed that PWE significantly increased the expression of serum motilin (MTL), gastrin (GAS), ADCY5/6, p-PKAα/β/γ cat, and phosphorylated cAMP-response element binding protein in the stomach, and AQP3 expression in the colon. Moreover, it decreased the levels of serum ADH, the expression of AQP3 and AQP4 in the stomach, AQP1 and AQP3 in the duodenum, and AQP4 in the colon. PWE induced diuresis to drain dampness in rats with DSSD. Eleven main effective components were identified in PWE. They exerted therapeutic effect by regulating the AC-cAMP-AQP signaling pathway in the stomach, MTL and GAS levels in the serum, AQP1 and AQP3 expression in the duodenum, and AQP3 and AQP4 expression in the colon.

Lipid-lowering Effect of Active Components in Common Chinese Medicine： A Review / 中国实验方剂学杂志

Dyslipidemia is a common metabolic disease caused by abnormal lipoprotein metabolism in human body. According to pathogenesis， it is divided into primary dyslipidemia and secondary dyslipidemia. The former is caused by genetic defects， and the latter is caused by diseases， drugs， unhealthy diets， and lifestyle. The clinical manifestations are xanthoma， arteriosclerosis， and other symptoms of coronary heart disease and peripheral vascular disease. Dyslipidemia can cause a variety of diseases， such as cardiovascular disease， diabetes， and cancer， seriously threatening people's quality of life and life safety， so the research on drugs against dyslipidemia is more urgent. In spite of manifest efficacy， chemical antilipemic agents such as lovastatin are accompanied by some adverse reactions， and there is recurrence after drug withdrawal. Compared with chemical drugs， Chinese medicine has the advantages of multi-pathway， multi-target， multi-level regulation of dyslipidemia， with few side effects. Modern medical research has shown that Chinese medicine can affect lipid synthesis， decomposition， and absorption and improve liver lipid and bile acid metabolism by regulating the peroxisome proliferator-activated receptor （PPAR） signaling pathway， AMP-activated protein kinase （AMPK） signaling pathway， cyclic adenosine monophosphate （cAMP） signaling pathway， adipocytokine signaling pathway， farnesoid X receptor （FXR）/small heterodimer partner （SHP） signaling pathway， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， etc.， thereby exerting a role in lowering lipid. Therefore， this paper summarized the mechanism of effective components in Chinese medicine in lowering blood lipid to provide new ideas and a theoretical basis for the prevention and treatment of lipid metabolic diseases by Chinese medicine in clinical practice.

"Six-step strategy" for effective compounds in Chinese medicinal prescriptions based on in vitro-in vivo integration and its application in research on component-based Chinese medicine / 中国中药杂志

The discovery and identification of effective components are pivotal in the research on Chinese medicinal prescriptions. Given two basic conditions for effective components in Chinese medicinal prescriptions, i.e., active structure and a certain level of drug exposure in the body(including the intestine), a "six-step strategy" for the effective compounds in Chinese medicinal prescriptions based on in vitro-in vivo integration(SSS for short) has been proposed and established, as well as the key technologies. SSS contains qualitative and quantitative analyses of components in five steps, including those in Chinese medicinal extract, intestinal contents, portal vein blood, liver, and peripheral blood. The components(prototype components and metabolites) with a certain exposure level(including in the intestine) and those with large differences between in vitro content and in vivo exposure or in exposure among various parts in the body are selected as the minority prioritized candidates. The sixth step is to screen the pharmacological activity of candidate components specifically extracted from Chinese medicinal materials or artificially synthesized. SSS can significantly narrow the screening range, enhance the hit rate, and speed up the identification of effective components specifically targeting indications. Based on the effective components identified by the SSS, the "upstream" can be linked(mechanism research based on the effective components with clear structures) and the "downstream" can be combined(development of innovative component-based Chinese medicine with definite pharmacodynamic composition). In this study, the concept of component-based Chinese medicine and specific applications of SSS in the development of component-based Chinese medicine are also introduced.

The areas suitable for growing and artificial cultivation introduction are those with high altitude，short annual average frost-free period，low annual rainfall，large average evaporation，long sunshine hours， and low annual average temperature.

New Progress in Mechanism of Salviae Miltiorrhizae Radix et Rhizoma in Treatment of Diabetes and Its Complications / 中国实验方剂学杂志

Diabetes is a worldwide public health problem that seriously threats human health. Long-term metabolic disorders， as the main cause of multi-system complications and death in the later stage of diabetes， can cause multi-system damage， leading to chronic progressive lesions in the eyes， kidneys， nerves， heart， blood vessels and other tissues and organs， as well as functional decline and failure. The low risk of side effects and new treatment strategies remain an area to be explored in clinical treatment of diabetes. Salviae Miltiorrhizae Radix et Rhizoma （SM） is one of the commonly used herbs in traditional Chinese medicine （TCM）， with the main effect of activating blood circulation and removing blood stasis. In recent years， it has been found that SM shows good performance in lowering blood sugar and treating diabetes complications. Data mining information has also shown that the drugs of activating blood circulation and removing blood stasis are now common drugs in clinical treatment of diabetes， and SM has the highest use frequency， with significant curative effect. In addition， TCM is a kind of treatment with composite components and multiple targets， and so people are increasingly interested in its effective components and carry out extensive researches. This article summarized the experimental verification of SM extract and its components （tanshinone A， tanshinone B， tanshinone ⅡA， tanshinone I， protocatechuic aldehyde， polysaccharide， and total polyphenol acid） in various diabetes models in improving glucolipid metabolism， improving heart function in patients with diabetes， alleviating the motor and sensory deficits caused by diabetes， preventing the occurence of the diabetic retinopathy， recovery of liver and kidney structure and function damage in diabetic patients， and helping to resist high sugar-induced atrophic cavitation potential. It may inhibit hyperglycemia-induced vascular injury with polyol pathway activation， reduce the formation of advanced glycation end products， inhibit protein kinase C pathway activation and hexosamine pathway activation， and alleviate oxidative stress caused by excessive production of peroxides in mitochondrial electron transport chain during hyperglycemia to play a role of treatment， and provide reference for clinical application.

This paper was to investigate the effect of Huanglian Jiedu Decoction(HLJD) on ulcerative colitis(UC) in mice, and determine the effective components in plasma, and virtually screen its therapeutic target, and predict its mechanism. Sixty Balb/c mice were randomly divided into blank group, model group, mesalazine treatment group(0.3 g·kg~(-1)), and HLJD treatment groups(24.66, 12.33, 6.17 g·kg~(-1)). Excepted for the blank group, all the mice in HLJD and mesalazine treatment groups were gavage administration. All mice freely drank 2.5% DSS solution for seven days to induce UC. The disease activity index(DAI) was detected each day. At the end of the experiment, HE staining was used to observe the pathological changes in colon. The content of IL-1β, IL-6 and TNF-α in colon were determined by ELISA. The effective components in plasma were determined by UPLC-Q-TOF-MS. The reverse docking in PharmMapper was used to screen the component targets. The disease targets of UC were collected by searching TTD, OMIM and GeneCards databases. The intersection of the component targets and disease targets was selected as the therapeutic targets. Then the therapeutic targets were imported into the STRING for GO and KEGG enrichment analysis. Discovery Studio was used to simulate the docking between the components and the targets. RESULTS:: showed that the DAI in the model group increased significantly(P<0.05), and the number of inflammatory cells and infiltration degree increased significantly compared with the blank group. The DAI in HLJD treatment group was significantly reduced(P<0.05), and the number and infiltration degree of inflammatory cells were reduced compared with the model group. The ELISA results showed that the levels of IL-1β, IL-6 and TNF-α were increased significantly in the model group(P<0.01) compared with the blank group, and significantly down regulated in the HLJD treatment group(P<0.05) compared with the model group. After UPLC-Q-TOF-MS analyse, ten components were identified. The network pharmacology analysis showed that the action targets were significantly enriched in 129 of biological processes, such as response to organic substance, chemical and oxygen-containing compound, etc., as well as 16 of signal pathways, such as IL-17, TNF and hepatitis B signal pathways, were enriched too. The results of molecular docking showed that limonin, palmatine and berberine could bind to CASP3 and MMP9 by hydrogen bond. In conclusion, HLJD could alleviate the colonic mucosal inflammatory infiltration and mucosal damage in UC mice. The mechanism may be related to the anti-inflammatory effect on UC mice by reducing the levels of IL-1β, IL-6 and TNF-α in colon through limonin, palmatine and berberine regulating IL-17 signal pathway and TNF signal pathway via CASP3 and MMP9 meditated.

Research progress on effective components of Chinese materia medica in regulating autophagy / 中国中药杂志

Autophagy is a highly conservative and multi-component activated energy metabolism and self-renewal mechanism, which plays a crucial regulatory role in maintaining the normal physiological state of cells and is involved in various pathological processes. In recent years, the mechanism study has made great progress in regulating autophagy with effective components of Chinese materia medica(CMM),which are reported to prevent and treat cancers, neurodegenerative diseases, cardiovascular diseases and metabolic and immune-related diseases. This review outlines the molecular regulation mechanisms of cell autophagy with CMM components in controlling the above-mentioned diseases. There are many relevant reports on the regulatory mechanisms of autophagy in tumor and cardiovascular cells with CMM monomers. The main chemical structural types are alkaloids, saponins, polyphenols, flavonoids and terpenes. And m-TOR pathway is the main mechanism relating to the regulatory mechanisms of autophagy with CMM. Therefore, the regulatory mec-hanisms of cell autophagy become a new research targeting strategy of therapies with CMM. This review provides evidences for the effectiveness and scientificity of CMM in regulating autophagy, in the expectation of providing references for the in-depth studies of CMM in the field of autophagy and the development of natural autophagy regulators.

Pharmacokinetics of compatible effective components of Mahuang Decoction in febrile rats / 中国中药杂志

In the present paper,after the febrile rat model was prepared by injecting yeast,orthogonally compatible effective components from prescription drugs of Mahuang Decoction( Ephedra sinica total alkaloids,Cinnamomum cassia essential oil,amygdalin,Glycyrrhiza uralensis total flavonoids+G. uralensis total saponins) with nine different dosage ratios were given by gavage administration.The plasma concentrations of main active ingredients including ephedrine hydrochloride,pseudoephedrine hydrochloride,methylephedrine hydrochloride,cinnamic acid,amygdalin,liquritin and glycyrrhizin at different time points were analyzed by liquid chromatograph mass spectrometer( LC-MS). Based on the pharmacokinetic parameters of non-compartmental model,the area under curve of total quantum( AUCt) and the mean chromatographic retention time of total quantum( MRTt) were further calculated,in order to evaluate the effect of compatibility on the total statistical moment parameters. The results showed that the pharmacokinetic characteristics of main active components in febrile rats were significantly different after treatment with orthogonally compatibility of E. sinica total alkaloids,C.cassia essential oil,amygdalin,G. uralensis total flavonoids and G. uralensis total saponins. Orthogonal analysis confirmed that different compatibility components had different effects on the total statistical moment parameters. The contribution of effective components of Mahuang Decoction to AUCtwas as follows in a descending order: E. sinica total alkaloids>C. cassia essential oil>amygdalin>G. uralensis total flavonoids+G. uralensis total saponin,while the contribution to MRTtwas: E. sinica total alkaloids >G. uralensis total flavonoids+G. uralensis total saponin>amygdalin>C. cassia essential oil. The E. sinica total alkaloid had the greatest effects on both of the above parameters,and the optimal combination was A_3B_3C_2D_1 for AUCt,and A_1B_1C_1D_1 for MRTt.
