Curcuma kwangsiensis root tuber is a widely used genuine medicinal material in Guangxi, with the main active components of terpenoids and curcumins. It has the effects of promoting blood circulation to relieve pain, moving Qi to relieve depression, clearing heart and cooling blood, promoting gallbladder function and anti-icterus. Modern research has proved its functions in liver protection, anti-tumor, anti-oxidation, blood lipid reduction and immunosuppression. Considering the research progress of C. kwangsiensis root tubers and the core concept of quality marker(Q-marker), we predicted the Q-markers of C. kwangsiensis root tubers from plant phylogeny, chemical component specificity, traditional pharmacodynamic properties, new pharmacodynamic uses, chemical component measurability, processing methods, compatibility, and components migrating to blood. Curcumin, curcumol, curcumadiol, curcumenol, curdione, germacrone, and β-elemene may be the possible Q-markers. Based on the predicted Q-markers, the mechanisms of the liver-protecting and anti-tumor activities of C. kwangsiensis root tubers were analyzed. AKT1, IL6, EGFR, and STAT3 were identified as the key targets, and neuroactive ligand-receptor interaction signaling pathway, nitrogen metabolism pathway, cancer pathway, and hepatitis B pathway were the major involved pathways. This review provides a basis for the quality evaluation and product development of C. kwangsiensis root tubers and gives insights into the research on Chinese medicinal materials.

Both raw and vinegar products of the rhizome of Curcuma phaeocaulis are common drugs for promoting blood circulation and removing blood stasis in traditional Chinese medicine,which could be reflected in the inhibition of tail thrombosis in mice. As the traditional processing theory instructs,vinegar tastes sour and bitter,but can activate blood circulation and remove stasis after being infiltrated into the rhizome of C. phaeocaulis as an excipient. In this study,under the help of the ultrafast liquid chromatography-quadrupole time-offlight mass spectrometry( UFLC-Q-TOF-MS),the spectrum-effect relationship between the inhibition of tail thrombosis in mice and the rhizome of C. phaeocaulis both before and after the vinegar processing,were established to explore the functional changes of blood circulation and stasis after vinegar process. Based on the peak area from the fingerprint of UFLC-Q-TOF-MS of the alcohol extracts from the raw and vinegar-processed rhizome of C. phaeocaulis and their efficacy for inhibiting tail thrombosis,the correlation between the chromatography of UFLC-Q-TOF-MS and the inhibition of tail thrombosis in mice were analyzed by orthogonal partial least squares discriminant analysis( OPLS-DA) method. The results,produced by Simca-P software,showed that effective components consisted of eight peaks 16,24( aromadendrene oxide),3,11,22( dehydro-α-curcumene),19[( R)-(-)-α-curcumene],23 and 10 from the fingerprint,making great contribution to distinguish C. phaeocaulis raw products and the corresponding vinegar processed products. Therefore,from the perspective of inhibiting the formation of tail thrombosis in mice,the marker components could be found through the spectrum-effect relationship to distinguish C.phaeocaulis raw and vinegar products. This study provided new basis to explain the difference between the raw and the processed products of traditional Chinese medicine in the functional change of promoting blood circulation and removing blood stasis.

The chemical constituents and action targets of Acori Tatarinowii Rhizoma and Curcumae Radix were screened by network pharmacological method,and the mechanism of the combination of Acori Tatarinowii Rhizoma and Curcumae Radix in the treatment of epilepsy was analyzed. All chemical constituents of Acori Tatarinowii Rhizoma and Curcumae Radix were retrieved by TCMSP,and their action targets were screened. Component target PPI network was constructed. Epilepsy-related genes were retrieved from PharmGkb database,and PPI networks of disease targets were drawn by Cytoscape software. Cytoscape software was used to merge the network,screen the core network,and further analyze the gene GO function and KEGG pathway enrichment,which was verified by experimental research. One hundred and five chemical constituents of Acori Tatarinowii Rhizoma and 222 chemical constituents of Curcumae Radix were retrieved. Nineteen compounds were selected as candidate compounds according to OB and DL values. Among them,4 chemical constituents of Acori Tatarinowii Rhizoma and 15 chemical constituents of Curcumae Radix were found. A total of 88 target proteins were retrieved by retrieving TCMSP data,and PPI network was constructed. Through PharmGkb database,29 epilepsy-related genes were retrieved and disease target network was established. Cytoscape software and plug-ins were used for network merging and core network screening,and 69 genes were screened out. Through GO function analysis and KEGG pathway analysis,the mechanism of anti-epilepsy is related to prolactin signaling pathway,HTLV-Ⅰ infection signaling pathway,MAPK signaling pathway and herpes simplex infection signaling pathway. Further experimental verification showed that the serum prolactin level in epileptic rats was significantly increased. The neurons in hippocampal CA1 area degenerated,necrotized and lost 24 hours after epileptic seizure,and some neuron interstitial edema occurred. The possible mechanism of compatibility of Acori Tatarinowii Rhizoma and Curcumae Radix is related to serum prolactin level,MAPK signaling pathway,HTLV-Ⅰ infection and herpes simplex infection. The analysis may be related to viral encephalitis caused by HTLV-Ⅰ virus and herpes simplex infection,which damages nerve cells and causes seizures.

Curcumae Longae Rhizoma,Curcumae Radix and Curcumae Rhizoma are different medicinal parts of the same plant.Nevertheless,they are different in medicinal effects due to the different Chinese herbal nature. In this study,traditional Chinese medicines database( TCMD2009),traditional Chinese medicine system( TCMSP),and Ch EMBL database were retrieved to screen the active components and targets,and construct the target PPI network. By a graph theoretic clustering algorithm identifying protein complex algorithm( IPCA),the protein modules were identified and analyzed by gene ontology( GO) enrichment. A comparative study of Curcumae Longae Rhizoma and Curcumae Radix illustrate that Curcumae Longae Rhizoma regulates blood coagulation through P2 RY12,GNG2 and other genes to exert the analgesic effect. Curcumae Radix regulates lipid metabolism,plasma lipoprotein particle levels,platelet activation,response to oxidative stress,apoptotic process through LDLR,APOB,PRKCA,SOD1,TP53 and other genes to perform a function in clearing the heart and cooling the blood. A comparative study of Curcumae Radix and Curcumae Rhizoma demonstrate that Curcumae Rhizoma on regulates the nervous system by GRIA2,GRIA4 and other genes to exert blood-breaking effect; Curcumae Radix regulates lipid metabolism,plasma lipoprotein particle levels,platelet activation,response to oxidative stress,apoptotic process by genes such as CALM1,LPL,APOB,SOD1 and TP53 to play the role of clearing heart and cooling blood.

Curcumae Rhizoma is a Chinese medicinal herb that is contraindicated during pregnancy. Cold-congelation and blood-stasis are corresponding syndromes to Curcumae Rhizoma. Whether syndrome-based treatment is associated with developmental neurotoxicity of Curcumae Rhizoma remains to be unclear. To verify the theory of traditional Chinese medicine of "syndrome-based treatment during pregnancy", the present study induced the mice blood stasis model by immersing mice in ice water. Pregnant C57 BL/6 wild type(WT) mice and pregnant Nrf2 knock out(KO) mice were randomly divided into control groups and Rhizoma Curcumae exposure groups. The mice were exposed to Rhizoma Curcumae during day 5 to day 18 after pregnancy. The neurodevelopment was examined to evaluate the differences of developmental neurotoxicity between normal and blood-stasis pregnant mice exposed to Rhizoma Curcumae. caspase-3 and caspase-9 activity in brain of the offspring were measured by colorimetric assays. Bcl-2 mRNA and protein expression in brain of the offspring were examined by Real-time RT-PCR and Western blot, respectively. According to the findings, C57 BL/6 mice exposed to Rhizoma Curcumae(10.0 g·kg~(-1)) had a longer positive occurring time of the surface righting reflex test of offspring and higher caspase-3 and caspase-9 activities in brain of offspring, compared with the normal control group, but with no significant change in those of blood-stasis pregnant mice offspring. However, mice exposed to Rhizoma Curcumae(10.0 g·kg~(-1)) showed no change in Bcl-2 gene expression and p38 MAPK phosphorylation in brain of the offspring. Nrf2 gene knockout using CRISPR/Cas9 resulted in a longer positive occurring time of the surface righting reflex test of offspring and higher caspase-3 and caspase-9 activities in brain of offspring. In conclusion, developmental neurotoxicity of the blood-stasis pregnant mice exposed to Rhizoma Curcumae was weaker than that of the normal pregnant mice. Nrf2 activation involved in the phenomenon of Rhizoma Curcumae of "syndrome-based treatment during pregnancy", but the upstream signal pathway mechanism value shall be further investigated.

The dynamic accumulation rule of active substances in medicinal plants is of great value not only for medicinal material production and application,but also for the genetic mechanism study on the formation of medicinal ingredients,especially vital to guide medicinal material collection as well as experiment material selection and candidate gene screening in the analysis of biosynthesis pathway. This study investigated the accumulation of curcumins and terpenoids,and the biosynthesis of these metabolites,which are the active metabolites in Curcuma longa,a commonly used traditional Chinese medicine. Rhizoma of C. longa from leaf growing period,rhizome swelling period and dry matter accumulating period were used as experimental materials,to analyze the changes of metabolites and biosynthesis in the three periods by comparative transcriptome and metabolomes analysis.The results indicated that terpenoids accumulation and biosynthesis mainly occurred in leaf growing period,while curcumin accumulation and biosynthesis mainly occurred in dry matter accumulating period. Therefore,we suggested that turmeric rhizomes in leaf growth period were suitable for terpenoids biosynthetic pathway characterization,and rhizome in accumulation of dry matter period was suitable for curcuminoid biosynthesis pathway characterization. This study provides references for medicinal materialproduction and application,as well as biopathway analysis of active compounds for C. longa.

Traditional Chinese medicine Curcuma Zedoary ( E'Zhu) contains essential oil, curcuminoid and other effective constituents, with such pharmacological actions as anti-platelet aggregation, lowing blood lipid, anti-oxidation and anti-inflammation. In recent years, studies have showed that certain extracts and chemical components of E'Zhu could mitigate myocardial cell mitochondria injury and protect vascular endothelium by enhancing heme oxygenase-1 activity, inhibit nuclear factor NF-kappaB, target genes interleukin-associated kinase-1 (IRAK-1), tumor necrosis factor receptor-6 (TRAF-6) and vascular cell adhesion molecule-1 (VCAM-1), reduce inflammatory infiltration, and inhibit growth factor-induced smooth muscle cells (SMCs) proliferation and migration by impacting oxidation of cellular phosphatases. Due to its different functions in vascular endothelial cells and smooth muscle cells, E'Zhu has been applied in drug-eluting stents, with a potential effect in preventing in-stent restenosis and thrombogenesis. In this paper, studies on pharmacological effects and mechanisms of extracts and main chemical constituents from E'Zhu in preventing vascular restenosis were summarized.
