Xinkeshu tablets promote angiogenesis in zebrafish embryos and human umbilical vein endothelial cells through multiple signaling pathways.

ETHNOPHARMACOLOGICAL RELEVANCE: Angiogenesis is particularly important in ischemic cardiovascular diseases such as coronary heart disease (CHD). Xinkeshu tablets (XKS) are a commonly used Chinese patent medicine for CHD with a defined clinical effect. However, the proangiogenic effect of XKS remains unknown. AIM OF THE STUDY: We attempted to investigate the chemical composition and proangiogenic effect of XKS, as well as its underlying mechanisms. MATERIALS AND METHODS: The chemical composition of a XKS methanol extract was analyzed using a UPLC-Q-Orbitrap-MS system. The compound's proangiogenic effects were evaluated in zebrafish embryos and human umbilical vein endothelial cells (HUVECs). Furthermore, the underlying mechanisms were investigated using transcriptome assays and real-time quantitative PCR validation. RESULTS: We identified 116 chemical constituents of XKS. XKS significantly stimulated subintestinal vessel plexus (SIVs) growth and rescued tyrosine kinase inhibitor (PTK787)-induced intersegmental vessels (ISVs) injury in zebrafish in a concentration-dependent manner. XKS significantly rescued the proliferation, migration capacity and tube formation of Recombinant VEGFR tyrosine kinase inhibitor II (VRI)-injured HUVECs. XKS promoted angiogenesis through multiple signaling pathways, including metabolic pathways, the PPAR signaling pathway, the AGE-RAGE signaling pathway, the NOD-like receptor signaling pathway, the VEGF signaling pathway, and the PI3K/Akt signaling pathway. CONCLUSION: Herein, we identified 116 chemical constituents of XKS for the first time and demonstrated that XKS may regulate angiogenesis through multiple signaling pathways to treat CHD.

Crosslinked albumin-manganese nanoaggregates with sensitized T1 relaxivity and indocyanine green loading for multimodal imaging and cancer phototherapy.

Albumin-manganese-based nanocomposites (AMNs) characterized by simple preparation and good biocompatibility have been widely used for in vivo T1-weighted magnetic resonance imaging (MRI) and cancer theranostics. Herein, an aggregation and crosslinking assembly strategy was proposed to achieve the sensitization to T1 relaxivity of the albumin-manganese nanocomposite. At a relatively low Mn content (0.35%), the aggregation and crosslinking of bovine serum albumin-MnO2 (BM) resulted in a dramatic increase of T1 relaxivity from 5.49 to 67.2 mM-1 s-1. Upon the loading of indocyanine green (ICG) into the crosslinked BM nanoaggregates (C-BM), the T1 relaxivity of the C-BM/ICG nanocomposite (C-BM/I) was further increased to 97.3 mM-1 s-1, which was much higher than those reported previously even at high Mn contents. Moreover, the presence of C-BM greatly enhanced the photoacoustic (PA) and photothermal effects of ICG at 830 and 808 nm, respectively, and the second near infrared fluorescence (NIR-II FL) of ICG also showed better stability. Therefore, the synthesized C-BM/ICG nanocomposite exhibited remarkable performance in in vivo multimodal imaging of tumors, such as T1-weighted MRI, NIR-II FL imaging and PA imaging, and cancer phototherapy with little side effects. This work provided a highly efficient and promising multifunctional nanoprobe for breaking through the limits of cancer theranostics, and opened a new avenue for the development of high-relaxivity AMNs and multimodal imaging methodology.

Optimization of a compact on-site stormwater runoff treatment system: Process performance and reactor design.

Stormwater runoff has become a major anthropogenic urban pollution source that threatens water quality. In this study, coagulation-sedimentation, and ammonium ion exchange and regeneration (AIR) modules were coupled as a CAIR system to efficiently treat stormwater runoff. In the coagulation module, 99.3%, 91.7%, and 97.0% of turbidity, total phosphorus, and chemical oxygen demand could be removed at an optimized poly-aluminum ferric chloride dosage of 30 mg/L, and the continuous experiment confirmed that the full load mode was more suitable for its rapid start-up. In the AIR module, dynamic ammonium removal indicated that the breakthrough time decreased with the rising initial concentration and superficial velocity. The Modified Dose Response (MDR) model described the ammonium exchange behavior better than the Thomas and the Bohart-Adams models. Then, a design flow of the ion exchange reactor was constructed by correlating constants in the MDR model with engineering parameters, and the ion exchange reactor was designed for continuous operation of the CAIR system. The average concentrations of chemical oxygen demand, total phosphorus, ammonium nitrogen, and total nitrogen in the effluent of the CAIR system were 7.22 ± 2.26, 0.17 ± 0.05, 1.49 ± 0.01, and 1.62 ± 0.02 mg/L, respectively. The almost unchanged exchange capacity and physicochemical properties after the multicycle operation confirmed the durability of zeolite for ion exchange. Techno-economic analysis suggested that the CAIR system is practically promising for stormwater management with efficient pollutants removal, small footprint, and acceptable operating cost.

Tapinanthus species: A review of botany and biology, secondary metabolites, ethnomedical uses, current pharmacology and toxicology.

ETHNOPHARMACOLOGICAL RELEVANCE: Tapinanthus species are hemiparasites that grow on diverse hosts in African regions. Tapinanthus species are locally known as "all purpose herbs" as they are traditionally used to treat various diseases such as diabetes, hypertension, cancer, inflammation, malaria, anemia, anxiety, itching, and so on. AIM OF THE STUDY: A comprehensive review on research outcomes and future perspectives of Tapinanthus species are presented to provide a reference for relevant researchers. MATERIALS AND METHODS: The references regarding Tapinanthus species were retrieved from Google Scholar, Web of Science, Sci-finder, PubMed, Elsevier, Wiley, China National Knowledge Infrastructure, Open Access Library, and SpringerLink between 1963 and 2022. Scientific plant names were provided by "The Plant List" (www.theplantlist.org) and "The world Flora Online" (www.worldfloraonline.org). RESULTS: Even though Tapinanthus species are regarded as notorious pests that can undermine various hosts, they are, as omnipotent herbs in folklore, meaningful for the development of potential phytomedicine sources. Phytochemistry screening has revealed the presence of glycosides, triterpenoids, flavonoids, alkaloids, tannins, steroids, anthraquinones. Among them, the chemical structures of 40 compounds have been elucidated by phytochemical methods without alkaloids and anthraquinones. These secondary metabolites might be responsible for ethnomedical uses and bioactivities of Tapinanthus species. Current research has provided scientific evidence for traditional uses of Tapinanthus species, especially unraveling hypoglycemic, hepatoprotective, antioxidant, antibacterial, anti-anxiety, anti-depression, anti-inflammatory, and other pharmacological properties. Given the fact that ethnomedical uses served as a valuable reference for pharmacology, however, some records to treat arthritis, fever, itching, dysentery, stomach pain, and anemia, have not been confirmed in current research. Furthermore, the toxic effects of Tapinanthus species were susceptible to the dosages, with relative safety across a wide range. CONCLUSIONS: To reasonably yield Tapinanthus species, artificial culture might be a promising method to develop in the future. The discrepancies between phytochemistry screening and structure elucidation, as well as between ethnomedical uses and current pharmacology, need to be further clarified. The identification of bioactive compounds in crude extracts and fractions, the illustration of the underlying mechanisms of pharmacology, along with the addition of cytotoxicity, genotoxicity, and clinical trials of toxic tests, should be carried out in depth. This review highlights that Tapinanthus species can be considered promising phytomedicine sources as long as we adhere to digging more deeply into their potential role.

Hesperetin Inhibits TGF-ß1-Induced Migration and Invasion of Triple Negative Breast Cancer MDA-MB-231 Cells via Suppressing Fyn/Paxillin/RhoA Pathway.

Triple-negative breast cancer is an aggressive subtype of breast cancer with poor clinical outcomes and poor prognosis. Hesperetin is an active component extracted from Citrus fruits and Traditional Chinese Medicine has a wide range of pharmacological effects. Here, we assessed the anti-migration and anti-invasive effects and explored inhibitory mechanisms of hesperetin on metastasis of human triple negative breast cancer MDA-MB-231 cells. Cell viability experiments revealed that 200 µM hesperetin has a clear inhibitory effect on MDA-MB-231 cells. TGF-ß1 treatment induces apparent tumor progression in MDA-MB-231 cells including aberrant wound-healing and invasion ability, which is effectively suppressed by hesperetin co-treatment. Additionally, hesperetin inhibited the TGF-ß1-mediated actin stress fiber formation. Western blot results showed that hesperetin suppressed the TGF-ß1-mediated (i) activation of Fyn, (ii) phosphorylation of paxillin at Y31, Y88, and Y118 sites, (iii) the increased expression of RhoA, and (iv) activation of Rho-kinase. We demonstrated the increased interaction of Fyn with paxillin and RhoA protein in the TGF-ß1-induced metastasis of MDA-MB-231 cells. Small interfering RNA Fyn inhibited phosphorylation of paxillin (Y31) and activation of Rho-kinase induced by TGF-ß1. In conclusion, hesperetin has a significant inhibitory effect on migration and invasion of MDA-MB-231 cells induced by TGF-ß1, which might be attributed to inhibiting the Fyn/paxillin/RhoA pathway.

[Neuroprotective effect of cinnamaldehyde in MPTP-induced mouse model of subacute Parkinson's disease].

This paper aims to explore the neuroprotective effect of cinnamaldehyde(CA) in mice with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced subacute Parkinson's disease(PD) and the mechanism. To be specific, male C57 BL/6 mice(n=72, SPF) were randomized into control group, model group, positive control(madopar 0.1 mg·g~(-1)) group, and low-dose, me-dium-dose, and high-dose CA groups(0.15, 0.30, 0.60 mg·g~(-1)). MPTP(intraperitoneal injection, 0.03 mg·g~(-1), once a day for 5 days) was used to induce subacute PD in mice except for the control group. The administration began from the day of modeling and lasted 19 days. On the 0 th, 12 th, and 19 th day, the open field test, pole test, and rotarod test were carried out. After the tests, the mice were killed and brains were separated. In addition, the organ index was measured. The number of cells in substantia nigra(SN) in the midbrain of MPTP-induced PD model mice was detected based on hematoxylin and eosin(HE) staining. The levels of tyrosine hydroxylase(TH)-and α-synuclein(α-Syn)-positive cells in SN were determined by immunohistochemical staining, and the protein levels of TH and α-Syn in SN by Western blot. The results showed that the MPTP-stimulated mice had abnormal behaviors such as erect hair, arched back, rigidity of the tail, slow movement, and tremor, decreased number of crossings and rearing, increased frequency of urination and defecation, longer time of pole climbing, and shorter time of staying on the rotating rod. In addition, the mice showed obvious damage of neurons in the SN and reduced neuron cells in irregular arrangement with some shrinking. In addition, the average optical density of TH in SN decreased and that of α-Syn increased. All these suggested the successful modeling. CA displayed obvious therapeutic effect on the PD mice, as manifested by the increased number of crossings and rearing, decreased frequency of urination and defecation, shorter time of climbing pole, longer time of staying on the rotating rod, and more neuron cells in the SN with a few pykno-tic cells. Moreover, CA significantly alleviated the decrease of TH and the overexpression of α-Syn in SN. As a result, the MPTP-induced injury of dopaminergic neurons was alleviated. The performance of 0.3 mg·g~(-1) CA was the best. This study is expected to lay a scientific basis for the development of CA products.

Enhanced nutrient removal from stormwater runoff by a compact on-site treatment system.

Efficient and space-saving technologies for on-site treatment of stormwater runoff are required to control water pollution in the urban surface. The intermittent nature of stormwater runoff and extremely limited land available greatly hindered the application of current wastewater treatment technologies, and thus synchronous removal of multiple contaminants (especially for nutrient) efficiently was failed by current processes. In this study, a new compact CFFA treatment system, consisting of coagulation, flocculation, filtration and ammonium ion exchange units, was constructed for on-site treatment of stormwater runoff based on batch test optimization and pilot-scale test verification. The coagulation process effectively aggregated particles and precipitated phosphorus by dosing Al2(SO4)3, while flocculation using anionic polyacrylamide further enlarged particle size for efficient micromesh filtration. The dynamic micromesh filtration obtained turbidity and phosphorus removal efficiencies comparable to 30 min gravity settling with greatly smaller footprint. Ion exchange by zeolite showed higher exchange capacity owing to lower initial ammonium nitrogen concentration in the stormwater runoff. The pilot-scale experiments with treatment capacity of 1 L/s showed that the CFFA treatment system achieved synchronous removal of particles (97.2%), nitrogen (79.7%), phosphorus (95.0%) and organic matters (83.3%) efficiently within short hydraulic retention time of 0.35 h, yielding effluent with chemical oxygen demand, suspended solids, total phosphorus and total nitrogen of 38.7, 7.80, 0.22 and 2.80 mg/L, respectively. The CFFA treatment system had the highest pollutant removal loads compared to reported runoff treatment processes in literatures, and was well suited to on-site treatment of stormwater runoff with high space utilization efficiency.

Integration of Artificial Intelligence, Blockchain, and Wearable Technology for Chronic Disease Management: A New Paradigm in Smart Healthcare.

Chronic diseases are a growing concern worldwide, with nearly 25% of adults suffering from one or more chronic health conditions, thus placing a heavy burden on individuals, families, and healthcare systems. With the advent of the "Smart Healthcare" era, a series of cutting-edge technologies has brought new experiences to the management of chronic diseases. Among them, smart wearable technology not only helps people pursue a healthier lifestyle but also provides a continuous flow of healthcare data for disease diagnosis and treatment by actively recording physiological parameters and tracking the metabolic state. However, how to organize and analyze the data to achieve the ultimate goal of improving chronic disease management, in terms of quality of life, patient outcomes, and privacy protection, is an urgent issue that needs to be addressed. Artificial intelligence (AI) can provide intelligent suggestions by analyzing a patient's physiological data from wearable devices for the diagnosis and treatment of diseases. In addition, blockchain can improve healthcare services by authorizing decentralized data sharing, protecting the privacy of users, providing data empowerment, and ensuring the reliability of data management. Integrating AI, blockchain, and wearable technology could optimize the existing chronic disease management models, with a shift from a hospital-centered model to a patient-centered one. In this paper, we conceptually demonstrate a patient-centric technical framework based on AI, blockchain, and wearable technology and further explore the application of these integrated technologies in chronic disease management. Finally, the shortcomings of this new paradigm and future research directions are also discussed.

Melatonin induces the rejuvenation of long-term ex vivo expanded periodontal ligament stem cells by modulating the autophagic process.

BACKGROUND: Stem cells that have undergone long-term ex vivo expansion are most likely functionally compromised (namely cellular senescence) in terms of their stem cell properties and therapeutic potential. Due to its ability to attenuate cellular senescence, melatonin (MLT) has been proposed as an adjuvant in long-term cell expansion protocols, but the mechanism underlying MLT-induced cell rejuvenation remains largely unknown. METHODS: Human periodontal ligament stem cells (PDLSCs) were isolated and cultured ex vivo for up to 15 passages, and cells from passages 2, 7, and 15 (P2, P7, and P15) were used to investigate cellular senescence and autophagy change in response to long-term expansion and indeed the following MLT treatment. Next, we examined whether MLT could induce cell rejuvenation by restoring the autophagic processes of damaged cells and explored the underlying signaling pathways. In this context, cellular senescence was indicated by senescence-associated ß-galactosidase (SA-ß-gal) activity and by the expression of senescence-related proteins, including p53, p21, p16, and γ-H2AX. In parallel, cell autophagic processes were evaluated by examining autophagic vesicles (by transmission electronic microscopy), autophagic flux (by assessing mRFP-GFP-LC3-transfected cells), and autophagy-associated proteins (by Western blot assay of Atg7, Beclin-1, LC3-II, and p62). RESULTS: We found that long-term in vitro passaging led to cell senescence along with impaired autophagy. As expected, MLT supplementation not only restored cells to a younger state but also restored autophagy in senescent cells. Additionally, we demonstrated that autophagy inhibitors could block MLT-induced cell rejuvenation. When the underlying signaling pathways involved were investigated, we found that the MLT receptor (MT) mediated MLT-related autophagy restoration by regulating the PI3K/AKT/mTOR signaling pathway. CONCLUSIONS: The present study suggests that MLT may attenuate long-term expansion-caused cellular senescence by restoring autophagy, most likely via the PI3K/AKT/mTOR signaling pathway in an MT-dependent manner. This is the first report identifying the involvement of MT-dependent PI3K/AKT/mTOR signaling in MLT-induced autophagy alteration, indicating a potential of autophagy-restoring agents such as MLT to be used in the development of optimized clinical-scale cell production protocols.

The cardioprotective and anxiolytic effects of Chaihujialonggumuli granule on rats with anxiety after acute myocardial infarction is partly mediated by suppression of CXCR4/NF-κB/GSDMD pathway.

AIMS: Over-expression of CXCR4 activates nuclear translocation of NF-κB, induces high expression of NLRP3, GSDMD, IL-1ß and IL-18, which promotes severe inflammatory response following myocardial infarction. Previous studies revealed inflammation induces anxiety after myocardial infarction. The Chaihujialonggumuli granule has anti-inflammatory properties and could tranquillize mind. But the mechanism of its efficacy remains unknown. This study was to investigate the possible mechanism of BFG on cardioprotective and anxiolytic. METHODS: The expression of CXCR4, NF-κB, NLRP3and GSDMD was measured with western-blot, QRT-PCR. The expression location of CXCR4, NLRP3, GSDMD were determined by immunohistochemistry. IL-1ß、IL-18 in the peripheral blood were measured by ELISA. HE staining, Masson staining and transmission electron microscopy were used to observe morphological changes of cardiomyocytes. Echocardiography was used to assess cardiac function after cardiac surgery. Elevated cross maze test and open field test were used to evaluate behaviours. Western blot was used to detect the protein expressions of 5-HT, DA, IL-1ß, IL-18 and neuron damage was investigated by Nissl staining in the hippocampus. RESULTS: The up-regulation of CXCR4, NF-κB, NLRP3 and GSDMD were found in the infarcted area after left coronary artery ligation. Pathological staining and analysis showed that more severe inflammatory cytokines infiltration, myocardial fibrosis, were found in myocardial tissue of the complex group rats. And when compared to the sham group, the levels of IL-1ß, IL-18 was increased of the complex group in both peripheral blood and brain. Behavioural test and echocardiography indicated that the rats in complex group exploration behaviours was significantly reduced, and with poor cardiac functional recovery. The AMD3100 had an inhibitory impact of CXCR4 on the activition of its downstream effectors, alleviating inflammatory reaction. Furthermore, the BFG decreased the expression level of CXCR4, NF-κB, GSDMD, NLRP3 in the infarcted area after myocardial infarction, when compared to the complex group. The assays in the brain indicated the BFG suppressed expression and activity of IL-1ß, IL-18, and improved 5-HT and DA synthesis. CONCLUSIONS: In sum, our study indicated that BFG may reduce inflammation, treat co-existing anxiety after myocardial infarction through inhibition of CXCR4/NF-κB/GSDMD signalling.

A PRISMA-compliant systematic review and meta-analysis of integrated Chinese and Western medicine in treating hepatitis C.

OBJECTIVE: To conduct a meta-analysis evaluating the effect of combining traditional Chinese medicine (TCM) with Western medicine in treating hepatitis C, and to provide an evidence-based medical strategy. METHODS: Randomized controlled trials (RCTs) comparing the effect of pegylated interferon (Peginterferon) combined with ribavirin (PR) alone and its combination with TCM were manually retrieved from the Weipu Information Resources System (VIP), Wan Fang Database, PubMed, and the Chinese Journal Full Text Database (CNKI). Studies meeting the inclusion criteria were selected and analyzed using the Review Manager 5.3 software. Suitable tests were also performed to determine the quality, heterogeneity, and sensitivity of the studies included in the meta-analysis. RESULTS: Twenty-eight RCTs met the inclusion criteria. The combination therapy or intervention group showed significantly greater HCV-RNA negative rate post-treatment compared to the monotherapy or the control group (P < .05). In addition, the serum levels of the liver function indicators alanine aminotransferase (ALT), aspartate aminotransferase (AST), and albumin (ALB) were significantly improved after the combination therapy compared to PR alone (P < .05), while total bilirubin (TB) and r-glutamyltransferase (GGT) levels were not affected by TCM (P > .05). Finally, the parameters of liver fibrosis were also reduced by the combination therapy more effectively than the monotherapy. CONCLUSION: The combination of TCM and PR can improve the Comprehensive Clinical Efficacy of hepatitis C and have a better negative rate of HCV-RNA with a better benefit in the liver function. The effect of TCM + PR is better than that of PR alone in treating hepatitis C.

Fourth-generation quinolones in the treatment of Helicobacter pylori infection: A meta-analysis.

AIM: To assess the efficacy and safety of fourth-generation quinolones for Helicobacter pylori (H. pylori) eradication, we conducted this systematic review and meta-analysis of randomized clinical trials. METHODS: Major literature databases (PubMed, EMBASE and the Cochrane Central Register of Controlled Trials) were searched for relevant articles published prior to February 2018. We performed a meta-analysis of all randomized clinical trials that examined the efficacy of H. pylori eradication therapies and included fourth-generation quinolones in the experimental arm. Subgroup analyses by regions and different types of fourth-generation quinolones were also performed. RESULTS: Ten studies including a total of 2198 patients were assessed. A meta-analysis of randomized controlled trials showed that the eradication rate of therapies containing non-fourth-generation quinolones was significantly lower than that of therapies containing fourth-generation quinolones by intention-to-treat (ITT) analysis [75.4% vs 81.8%; odds ratio (OR) = 0.661; 95% confidence interval (CI): 0.447-0.977; P = 0.038]. This analysis also showed that the eradication rate of the therapies containing non-fourth-generation quinolones was inferior to that of therapies containing fourth-generation quinolones by per-protocol analysis (79.1% vs 84.7%; OR = 0.663; 95%CI: 0.433-1.016; P = 0.059). Moreover, the occurrence of side effects was significantly different between the control and experimental groups by ITT analysis (30.6% vs 19.5%; OR = 1.874; 95%CI: 1.120-3.137; P = 0.017). The sub-analyses also showed significant differences in moxifloxacin therapies vs other fourth-generation quinolone therapies (84.3% vs 71.9%) and in Asian vs European groups (76.7% vs 89.1%). CONCLUSION: Therapies containing fourth-generation quinolones achieved a poor eradication rate in the treatment of H. pylori infection. Such regimens might be useful as a rescue treatment based on antimicrobial susceptibility testing. Different antibiotics should be chosen in different regions.

Planar cell polarity gene Fuz triggers apoptosis in neurodegenerative disease models.

Planar cell polarity (PCP) describes a cell-cell communication process through which individual cells coordinate and align within the plane of a tissue. In this study, we show that overexpression of Fuz, a PCP gene, triggers neuronal apoptosis via the dishevelled/Rac1 GTPase/MEKK1/JNK/caspase signalling axis. Consistent with this finding, endogenous Fuz expression is upregulated in models of polyglutamine (polyQ) diseases and in fibroblasts from spinocerebellar ataxia type 3 (SCA3) patients. The disruption of this upregulation mitigates polyQ-induced neurodegeneration in Drosophila We show that the transcriptional regulator Yin Yang 1 (YY1) associates with the Fuz promoter. Overexpression of YY1 promotes the hypermethylation of Fuz promoter, causing transcriptional repression of Fuz Remarkably, YY1 protein is recruited to ATXN3-Q84 aggregates, which reduces the level of functional, soluble YY1, resulting in Fuz transcriptional derepression and induction of neuronal apoptosis. Furthermore, Fuz transcript level is elevated in amyloid beta-peptide, Tau and α-synuclein models, implicating its potential involvement in other neurodegenerative diseases, such as Alzheimer's and Parkinson's diseases. Taken together, this study unveils a generic Fuz-mediated apoptotic cell death pathway in neurodegenerative disorders.

Analysis of the main constituents of Changshu tablet and its spasmolysis effect against contraction induced by acetylcholine in the rat-isolated intestinal smooth muscle.

The Changshu tablet (CST), one kind of Chinese patent medicine with astringent to the intestine and relieving diarrhea, was made by the root of Rose odorata Sweet var. gigantean (Coll.et Hemsl.) Rehd.et Wils. Although CST has a long history of clinical application, but the research of its chemical composition is less. So the objective of this study was to investigate the main constituents and preliminarily research its effect of the contraction of isolated intestine in vitro. The contents of total polyphenols (126.23mg/g) and total triterpenoids (132.75mg/g) in CST were determined by ultraviolet spectrophotometry. Procyanidin B3, epigallo catechin, catechin, epicatechin, (-)-fisetinidol-(4α, 8)-(-)-catechin, (4α, 8)-(-)-fisetinidol-(-)-epicatechins and (+)-guibourtinidol-(4ß, 8)-epicatechin were identified and determined by high performance liquid chromatography and their contents were distributed from 0.04mg/g to 1.46 mg/g. CST showed significant inhibitory effect against acetylcholine-induced contraction on the rat-isolated intestinal smooth muscle with a dose-dependent manner from 0.06 to 0.6mg/mL. The maxim inhibition rates of CST on duodenum, jejunum, ileum and colon were 65.70±3.47%, 79.74±1.27%, 58.90±1.87% and 45.75±2.21% respectively. These results indicated that CST has a spasmolytic role in gastrointestinal motility which was probably mediated through inhibition of muscarinic receptors. All these findings promote the improvement of the quality control standard of CST and provide pharmacological foundation for clinical application of CST in gastrointestinal tract.

[Effects of Hemerocallis citrine baroni flavonids on CCl4-induced liver fibrosis of rats].

This study is designed to explore the possible effects of Hemerocallis citrina baroni flavonids (HCBF) on liver fibrosis induced by CCl4 in rats. The liver fibrosis model was induced by CCl4, and HCBF were administered by gastric perfusion at 25 and 50 mg x kg(-1) qd for 50 days, while the contents of alanine transaminase (ALT), aspartate aminotransferase (AST), gamma glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), superoxide dismutase (SOD), maleic dialdehyde (MDA) and transforming growth factor-ß1 (TGF-ß1) were measured and the contents of PINP were measured in liver tissue, and the expression of TGF-ß1 were observed by immunohistochemisty and Western blot. The pathological changes of liver tissue were examined by HE. The results showed that HCBF (25, 50 mg x kg(-1)) improved the liver function significantly through reducing the level of ALT, AST, GGT and ALP (P < 0.05 or P < 0.01), and increasing the content of SOD (P < 0.01), while reducing the content of MDA (P < 0.05 or P < 0.01), the expression of TGF-ß1 (P < 0.05) and the content of PINP (P < 0.05). The results suggest that HCBF (25, 50 mg x kg(-1)) may inhibit the liver injury induced by CCl4 by decreasing the oxidative stress.
