Abstract
BACKGROUND Dendrobium officinale flowers (DOF) have the effects of antiaging and nourishing yin, but it lacks pharmacological research on skin aging. OBJECTIVE Confirming the role of DOF in delaying skin aging based on the "in vitro animal-human" model. METHODS In this experiment, three kinds of free radical scavenging experiments in vitro, D-galactose-induced aging mouse model, and human antiaging efficacy test were used to test whether DOF can improve skin aging through anti-oxidation. RESULTS In vitro experiment shows that DOF has certain scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical, hydroxyl free radical, and superoxide free radical, and its IC50 is 0.2090 μg/mL, 15.020, and 1.217 mg/mL respectively. DOF can enhance the activities of T-AOC, SOD, CAT, and GSH Px in the serum of aging mice, increase the content of GSH, and reduce the content of MDA when administered with DOF of 1.0, 2.0, and 4.0 g/kg for 6 weeks. In addition, it can enhance the activity of SOD in the skin of aging mice, increase the content of Hyp, and decrease the content of MDA, activated Keap1/Nrf2 pathway in the skin of aging mice. Applying DOF with a concentration of 0.2 g/mL on the face for 8 weeks can significantly improve the skin water score and elasticity value, reduce facial wrinkles, pores, acne, and UV spots, and improve the facial brown spots and roughness. CONCLUSION DOF can significantly improve skin aging caused by oxidative stress, and its mechanism may be related to scavenging free radicals in the body and improving skin quality.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pitongshu (PTS) is a clinically effective empirical formula for the treatment of FD. The efficacy and safety of PTS have been demonstrated in randomized, controlled, double-blind trials, but there is a lack of understanding of the systematic evaluation of the efficacy of PTS and its material basis. OBJECTIVE To investigate the efficacy of PTS in Functional dyspepsia (FD) mice and possible Q-markers. METHOD In this study, we used "irregular feeding + chronic unpredictable chronic stimulation" to establish a mice model of FD with hepatogastric disharmony. The efficacy of PTS was assessed from hair condition, behavioral, pain, gastrointestinal function, and serum 5-HT, GAS, MTL levels in mice by instillation of different doses of PTS. In addition, the composition of drugs in blood was analyzed by LC-QTOF-MS and potential Q-markers were selected by combining network pharmacology, molecular docking and actual content. RESULT Our study showed that different doses of PTS increased pain threshold and writhing latency, decreased the number of writhings, increased gastric emptying rate and small intestinal propulsion rate, decreased total acidity of gastric contents and gastric acid secretion, and increased serum levels of 5-HT, GAS, and MTL in mice to different degrees. Enrichment analysis showed that PTS may be anti-FD through multiple pathways such as Serotonergic synapse, thyroid hormone signaling pathway, cholinergic synapse, and dopaminergic synapse. In addition, potential active ingredient substances were explored by LC-QTOF-MS combined with bioinformatics. Combined with the actual contentselected six constituents, hesperidin, neohesperidin, naringin, paeoniflorin, magnolol and honokiol, possible as Q-markers. CONCLUSION PTS may exert its anti-FD effects through multi-component, multi-target and multi-pathway". Constituents, hesperidin, neohesperidin, naringin, paeoniflorin, magnolol and honokiol may be the Q-markers of its anti-FD effects.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder that is common in women of reproductive age. The clinical features of PCOS include hyperandrogenemia and polycystic ovarian changes. Bailing capsule (BL), a proprietary Chinese medicine that contains fermented Cordyceps sinensis powder, has been applied to treat PCOS. However, the specific active ingredients of BL and its mechanisms of action are yet to be elucidated. METHODS Initially, the effectiveness of BL on PCOS model mice was evaluated. Subsequently, the active ingredients of BL were searched in the TCMSP and TCM Systems Pharmacology databases, and their targets were predicted using Swiss Target Prediction and SEA databases. Furthermore, the GEO gene database was used to screen for differentially expressed genes (DEGs) related to PCOS. Data from Gene Card, OMIM, DDT, and Drugbank databases were then combined to establish a PCOS disease gene library. Cross targets were imported into the STRING database to construct a protein-protein interaction network. In addition, GO and KEGG pathway enrichment analyses were performed using Metascape and DAVID databases and visualized using Cytoscape software and R 4.2.3. The core targets were docked with SYBYL-X software, and their expressions in PCOS mice were further verified using qPCR. RESULTS The core active ingredients of BL were identified to be linoleyl acetate, cholesteryl palmitate, arachidonic acid, among others. Microarray data sets from four groups containing disease and normal samples were obtained from the GEO database. A total of 491 DEGs and 106 drug-disease cross genes were selected. Estrous cycle and ovarian lesions were found to be improved in PCOS model mice following BL treatment. While the levels of testosterone, progesterone, and prolactin decreased, that of estradiol increased. qPCR findings indicated that the expressions of JAK2, PPARG, PI3K, and AKT1 were upregulated, whereas those of ESR1 and IRS1 were downregulated in PCOS model mice. After the administration of BL, the expressions of associated genes were regulated. This study demonstrated that BL exerted anti-PCOS effects via PIK3CA, ESR1, AKT, PPARG, and IRS1 targets affecting PI3K-Akt signaling pathways. DISCUSSION This research clarified the multicomponent, multitarget, and multichannel action of BL and provided a theoretical reference for further investigations on its pharmacological basis and molecular mechanisms against PCOS.

Abstract
This study investigated the molecular action mechanism of a compound herb, also known as the Dendrobium officinale throat-clearing formula (QYF), by using network pharmacology and animal experimental validation methods to treat chronic pharyngitis (CP). The active ingredients and disease targets of QYF were determined by searching the Batman-TCM and GeneCards databases. Subsequently, the drug-active ingredient-target and protein-protein interaction networks were constructed, and the core targets were obtained through network topology. The Metascape database was screened, and the core targets were enriched with Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes. In total, 1403 and 241 potential targets for drugs and diseases, respectively, and 81 intersecting targets were yielded. The core targets included TNF, IL-6, and IL-1β, and the core pathways included PI3K-Akt. The QYF treatment group exhibited effectively improved general signs, enhanced anti-inflammatory ability in vitro, reduced serum and tissue expressions of TNF-α, IL-6, and IL-1β inflammatory factors, and decreased blood LPS levels and Myd88, TLR4, PI3K, Akt, and NF-κB p65 protein expression in the tissues. QYF could inhibit LPS production, which regulated the expression of the TLR4/PI3K/Akt/NF-κB signaling pathway to suppress the expression of the related inflammatory factors (i.e., TNF-α, IL-6, and IL-1β), thereby alleviating the CP process.

Abstract
AIM To explore the efficacy as well as the mechanism of action of Pitongshu (PTS) on rats with Functional dyspepsia (FD) induced by iodoacetamide gavage and tail clamping. METHODS The bioactive components of PTS were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), whereas the potential targets of PTS were obtained from the Similarity Ensemble Approach (SEA), TCMSP, and Swiss Target Prediction Database. The disease targets were obtained from DisGeNET database, whereas Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed using the R Software. The method of iodoacetamide gavage combined with tail clamping was used to establish FD rat model in this study. Body weight, food intake, gastrointestinal motility, gastric acidity and secretion, and the mechanical pain threshold of rats were measured. The open-field test was also performed. The stomach and duodenum were histologically observed. The levels of serotonin (5-HT), calcitonin gene related peptide (CGRP), motilin (MTL), and gastrin (GAS) in gastric tissues were detected by ELISA. RESULTS Totally 139 bioactive components and 17 potential targets of PTS were identified through a network pharmacology approach. The results of GO and KEGG enrichment analyses indicated that PTS could reduce 5-HT secretion of gastric tissues through the serotonergic synaptic pathway and alleviate the symptoms of FD, indicating that PTS plays a therapeutic role. The results of animal experiments showed that PTS could increase body weight and food intake, improve autonomous activity, and decrease gastric acidity and secretion in FD rats. Furthermore, gastric sensitivity increased in FD rats, and PTS treatment can significantly decrease it. The results of ELISA showed that the overexpression of 5-HT and CGRP were decreased after PTS treatment in FD rats. Lastly, PTS could significantly improve gastrointestinal motility, as well as the levels of GAS and MTL in FD rats. CONCLUSION PTS may reduce 5-HT secretion by regulating the serotonergic synaptic pathway, thereby reducing visceral sensitivity and alleviating the symptoms of FD.

Abstract
Metabolic hypertension (MH) is the most common type of hypertension worldwide because of unhealthy lifestyles, such as excessive alcohol intake and high-sugar/high-fat diets (ACHSFDs), adopted by humans. Poor diets lead to a decrease in the synthesis of short-chain fatty acids (SCFAs), which are produced by intestinal flora and transferred by G protein-coupled receptors (GPCRs), resulting in impaired gastrointestinal function, disrupted metabolic processes, increased blood pressure (BP), and ultimately, MH. It is not clear whether Dendrobium officinale polysaccharide (DOPS) can mediate its effects by triggering the SCFAs-GPCR43/41 pathway. In this study, DOPS, with a content of 54.45 ± 4.23% and composition of mannose, glucose, and galacturonic acid at mass percentages of 61.28, 31.87, and 2.53%, was isolated from Dendrobium officinale. It was observed that DOPS, given to rats by intragastric administration after dissolution, could lower the BP and improve the abnormal lipid metabolic processes in ACHSFD-induced MH rats. Moreover, DOPS was found to increase the production, transportation, and utilization of SCFAs, while improving the intestinal flora and strengthening the intestinal barrier, as well as increasing the intestinal levels of SCFAs and the expression of GPCR43/41. Furthermore, DOPS improved vascular endothelial function by increasing the expression of GPCR41 and endothelial nitric oxide synthase in the aorta and the nitric oxide level in the serum. However, these effects were all reversed by antibiotic use. These findings indicate that DOPS is the active component of Dendrobium officinale, and it can reverse MH in rats by activating the intestinal SCFAs-GPCR43/41 pathway.

Abstract
There are two types of abnormal hematopoiesis in solid tumor occurrence and treatment: pathological hematopoiesis, and myelosuppression induced by radiotherapy and chemotherapy. In this review, we primarily focus on the abnormal pathological hematopoietic differentiation in cancer induced by tumor-released granulocyte colony stimulating factor (G-CSF) and granulocyte-macrophage colony stimulating factor (GM-CSF). As key factors in hematopoietic development, G-CSF/GM-CSF are well-known facilitators of myelopoiesis and mobilization of hematopoietic stem cells (HSCs). In addition, these two cytokines can also promote or inhibit tumors, dependent on tumor type. In multiple cancer types, hematopoiesis is greatly enhanced and abnormal lineage differentiation is induced by these two cytokines. Here, dysregulated hematopoiesis induced by G-CSF/GM-CSF in solid tumors and its mechanism are summarized, and the prognostic value of G-CSF/GM-CSF-associated dysregulated hematopoiesis for tumor metastasis is also briefly highlighted.

Abstract
AIM Modified Suanzaoren Decoction (MSZRD) is obtained by improving Suanzaoren Decoction (SZRT), a traditional Chinese herbal prescription that has been used to treat insomnia for more than thousands of years. Our previous study showed that MSZRD can improve the gastrointestinal discomfort related insomnia by regulating Orexin-A. This study is the first study to evaluate the effects and possible mechanisms of MSZRD in mice with insomnia caused by p-chlorophenylalanine (PCPA) combined with multifactor random stimulation. METHODS After 14 days of multifactor stimulation to ICR mice, a PCPA suspension (30 mg/mL) was injected intraperitoneally for two consecutive days to establish an insomnia model. Three different doses of MSZRD (3.6, 7.2, and 14.4 g/kg/day) were given to ICR mice for 24 days. The food intake and back temperature were measured, and behavioral tests and pentobarbital sodium-induced sleep tests were conducted. The levels of Orexin-A, corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and adrenocortical hormones (CORT) in the serum and 5-hydroxytryptamine (5-HT), dopamine (DA), and norepinephrine (NE) in hypothalamus were measured using enzyme-linked immunosorbent assay (ELISA) kits. The levels of γ-aminobutyric acid (GABA) and glutamic acid (Glu) were measured by high-performance liquid chromatography (HPLC). The expression of 5HT1A receptor (5-HTRIA) and orexin receptor 2 antibody (OX2R) was measured by Western blot (WB) and immunohistochemical staining (ICH). Hematoxylin and eosin (H&E) staining and Nissl staining were used to assess the histological changes in hypothalamus tissue. RESULTS Of note, MSZRD can shorten the sleep latency of insomnia mice (P < 0.05, 0.01), prolonged the sleep duration of mice (P < 0.05, 0.01), and improve the circadian rhythm disorder relative to placebo-treated animals. Furthermore, MSZRD effectively increased the content of 5-HT and 5-HTR1A protein in the hypothalamus of insomnia mice (P < 0.05, 0.01), while downregulated the content of DA and NE (P < 0.05, 0.01). Importantly, serum GABA concentration was increased by treatment with MSZRD (P < 0.05), as reflected by a decreased Glu/GABA ratio (P < 0.05). Moreover, MSZRD decreased the levels of CORT, ACTH, and CRH related hormones in HPA axis (P < 0.05, 0.01). At the same time, MSZRD significantly downregulated the serum Orexin-A content in insomnia mice (P < 0.05), as well as hypothalamic OX2R expression (P < 0.05). In addition, MSZRD also improved the histopathological changes in hypothalamus in insomnia mice. CONCLUSION MSZRD has sleep-improvement effect in mice model of insomnia. The mechanism may be that regulating the expression of Orexin-A affects the homeostasis of HPA axis and the release of related neurotransmitters in mice with insomnia.

Abstract
As the number of patients with metabolic hypertension (MH) is increasing, there is an essential require for global measures to prevent and treat MH. Flavonoids such as buddleoside (BUD) from Chrysanthemum indicum L. are the main pharmacological components of cardiovascular activities. Previous studies have suggested that the buddleoside-rich Chrysanthemum indicum L. extract (BUDE) can reduce blood pressure in spontaneously hypertensive rats (SHR). However, its effect on MH and how it works remains to be researched. In this study, it was observed that BUDE could lower blood pressure, improve dyslipidemia, and decrease the level of plasma LPS in MH rats. Moreover, BUDE improved intestinal flora and increased the expression of occludin and claudin-1 in the colon, and improved the pathological injury of the colon. Western bolt and qRT-PCR experiments showed that BUDE could down-regulate TLR4 and MyD88 protein and mRNA expression and inhibit phosphorylation of IKKβ, IκBα and NF-κB p65 in vessels of MH rats. These results showed that BUDE could regulate intestinal flora, improve intestinal barrier function, reduce the production and penetration of LPS, thereby inhibiting the vascular TLR4/MyD88 pathway, improving vascular endothelial function, and ultimately lowering blood pressure in MH rats. This study provides a new mechanism of BUDE against MH by inhibiting the enteric-origin LPS/TLR4 pathway.

Abstract
Heavy metals are widely distributed in the environment due to the natural processes and anthropogenic human activities. Their migration into no contaminated areas contributing towards pollution of the ecosystems e.g. soils, plants, water and air. It is recognized that heavy metals due to their toxicity, long persistence in nature can accumulate in the trophic chain and cause organism dysfunction. Although the popularity of herbal medicine is rapidly increasing all over the world heavy metal toxicity has a great impact and importance on herbal plants and consequently affects the quality of herbal raw materials, herbal extracts, the safety and marketability of drugs. Effective control of heavy metal content in herbal plants using in pharmaceutical and food industries has become indispensable. Therefore, this review describes various important factors such as ecological and environmental pollution, cultivation and harvest of herbal plants and manufacturing processes which effects on the quality of herbal plants and then on Chinese herbal medicines which influence human health. This review also proposes possible management strategies to recover environmental sustainability and medication safety. About 276 published studies (1988-2021) are reviewed in this paper.

Abstract
Given the increasing global trend toward unhealthy lifestyles and dietary decisions, such as "over-consumption of alcohol, and high sugar and fat diets" (ACHSFDs), it is not surprising that metabolic hypertension (MH) is now the most common type of hypertension. There is an urgent, global need for effective measures for the prevention and treatment of MH. Improper diet leads to decreased short-chain fatty acid (SCFA) production in the gut, leading to decreased gastrointestinal function, metabolism, and blood pressure as a result of signaling through G-protein-coupled receptors (GPCRs), ultimately causing MH. Previous studies have suggested that Dendrobium officinale (DO) may improve gastrointestinal function, lower blood pressure, and regulate metabolic abnormalities, but it is not clear whether it acts on MH by increasing SCFA and, if so, how. In this research, it was observed that Dendrobium officinale ultrafine powder (DOFP) could lower blood pressure and improve lipid abnormalities in ACHSFD-induced MH model rats. Moreover, DOFP was found to improve the intestinal flora and increased the SCFA level in feces and serum, as well as increased the expressions of GPCR43/41 and eNOS and the nitric oxide (NO) level. An experiment on isolated aorta rings revealed that DOFP improved the vascular endothelial relaxation function in MH rats, and this effect could be blocked by the eNOS inhibitor l-NAME. These experimental results suggest that DOFP improved the intestinal flora and increased the production, transportation, and utilization of SCFA, activated the intestinal-vascular axis SCFA-GPCR43/41 pathway, improved vascular endothelial function, and finally lowered blood pressure in MH model rats. This research provides a new focus for the mechanism of the effect of DOFP against MH by triggering the enteric-origin SCFA-GPCR43/41 pathway.

Abstract
AIM AND OBJECTIVE Fructose, as a ubiquitous monosaccharide, can promote ATP consumption and elevate circulating uric acid (UA) levels. Our previous studies confirmed that the macroporous resin extract of Dendrobium officinale leaves (DoMRE) could reduce the UA level of rats with hyperuricemia induced by a high-purine diet. This study aimed to investigate whether DoMRE had a UA-lowering effect on rats with hyperuricemia caused by fructose combined with potassium oxonate, so as to further clarify the UA-lowering effect of DoMRE, and to explore the UA-lowering effect of DoMRE on both UA production and excretion. MATERIALS AND METHODS Rats with hyperuricemia induced by fructose and potassium oxonate were administered with DoMRE and vehicle control, respectively, to compare the effects of the drugs. At the end of the experiment, the serum uric acid (SUA) and creatinine (Cr) levels were measured using an automatic biochemical analyzer, the activities of xanthine oxidase (XOD) were measured using an assay kit, and the protein expression of urate transporter 1 (URAT1), glucose transporter 9 (GLUT9), and ATP-binding cassette superfamily G member 2 (ABCG2) were assessed using immunohistochemical and western blot analyses. Hematoxylin and eosin staining was used to assess the histological changes in the kidney, liver, and intestine. RESULTS Rats with hyperuricemia were induced by fructose and potassiumFructose and potassium induced hyperuricemia in rats. Meanwhile, the activities of XOD were markedly augmented, the expression of URAT1 and GLUT9 was promoted, and the expression of ABCG2 was reduced, which were conducive to the elevation of UA. However, exposure to DoMRE reversed these fructose- and potassium oxonate-induced negative alternations in rats. The activities of XOD were recovered to the normal level, reducing UA formation; the expression of URAT1, ABCG2, and GLUT9 returned to the normal level, resulting in an increase in renal urate excretion. CONCLUSION DoMRE reduces UA levels in rats with hyperuricemia induced by fructose combined with potassium oxonate by inhibiting XOD activity and regulating the expression of ABCG2, URAT1, and GLUT9. DoMRE is a potential therapeutic agent for treating hyperuricemia through inhibiting UA formation and promoting UA excretion.

Abstract
AIM AND OBJECTIVE The Dendrobium officinalis flower (DOF) is popular in China due to common belief in its anti-aging properties and positive effects on "nourish yin". However, there have been relatively few confirmatory pharmacological experiments conducted to date. The aim of this work was to evaluate whether DOF has beneficial effects on learning and memory in senescent rats, and, if so, to determine its potential mechanism of effect. MATERIALS AND METHODS SD rats were administrated orally DOF at a dose of 1.38, or 0.46 g/kg once a day for 8 weeks. Two other groups included a healthy untreated control group and a senescent control group. During the 7th week, a Morris water maze test was performed to assess learning and memory. At the end of the experiment, serum and brain samples were collected to measure concentrations of antioxidant enzymes, including malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione reductase (GSH-Px) in serum, and the neurotransmitters, including γ-aminobutyric acid (γ-GABA), Glutamic (Glu), and monoamine oxidase B (MAO-B) in the brain. Histopathology of the hippocampus was assessed using hematoxylin-eosin (H&E) staining. RESULTS The results suggested that treatment with DOF improved learning as measured by escape latency, total distance, and target quadrant time, and also increased levels of γ-GABA in the brain. In addition, DOF decreased the levels of MDA, Glu, and MAO-B, and improved SOD and GSHPx. Histopathological analysis showed that DOF also significantly reduced structural lesions and neurodegeneration in the hippocampus relative to untreated senescent rats. CONCLUSION DOF alleviated brain aging and improved the spatial learning abilities in senescent rats, potentially by attenuating oxidative stress and thus reducing hippocampal damage and balancing the release of neurotransmitters.

Abstract
AIMS AND OBJECTIVE Hypertension-induced stroke and coronary artery disease are significant causes of global morbidity and mortality. Metabolic hypertension has recently become the leading cause of hypertension. Flos Chrysanthemi Indici (CIF) has a long history as a treatment of hypertension as part of traditional Chinese medicine. However, its mechanisms of activity remain largely unknown. This study was aimed to uncover the potential anti-hypertensive mechanisms of CIF based on network pharmacology. MATERIALS AND METHODS In this research, a systems pharmacology approach integrating the measurement of active compounds, target fishing, gene screening, Gene Ontology (GO) pathway analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) Orthology Based Annotation System (KOBAS) database analysis, and compound-target network construction were performed to explore the anti-hypertensive mechanisms of CIF. RESULTS These studies revealed that 12 bioactive compounds in CIF had good druggability, 5 of which were flavonoids. After screening, 8 of those 12 bioactive compounds interacted with 118 hypertensionrelated target genes, which were mapped to 218 signal pathways. Network analysis showed that these targets were associated with improving insulin resistance, improving vascular function, inhibiting renninangiotensin- aldosterone system (RAAS), inhibiting the sympathetic nervous system (SNS) and regulating other physiological processes. CONCLUSION In summary, CIF is predicted to target multiple proteins and pathways to form a network that exerts systematic pharmacological effects in order to regulate blood pressure and metabolic disorder.

Abstract
Background Microcirculatory disturbance is closely associated with multiple diseases such as ischemic and septic stroke. Luteolin (3,4,5,7-tetrahydroxyflavone) is a vascular protective flavonoid present in several dietary foods. However, how luteolin plays a role in microcirculatory disturbance is still unknown. The purpose of this study was to find out the influence of luteolin on the lipopolysaccharide (LPS)-induced microcirculatory disturbance, focusing on its effect on leukocyte adhesion and the underlying mechanism of this effect. Methods After injecting LPS into rats, we used an inverted intravital microscope to observe the velocity of red blood cells in venules, numbers of leukocytes adherent to and emigrated across the venular wall, hydrogen peroxide production in venular walls and mast cell degranulation. Intestinal microcirculation blood flow was measured by High-resolution Laser Doppler Perfusion Imaging. Histological changes of small intestine and mesenteric arteries were evaluated. Additionally, cell adhesion stimulated by LPS was tested on EA.hy926 and THP-1 cells. The production of pro-inflammatory cytokines, adhesion molecules and the activation of TLR4/Myd88/NF-κB signaling pathway were determined. Results The results showed luteolin significantly inhibited LPS-induced leukocyte adhesion, hydrogen peroxide production and mast cell degranulation, and increased intestinal microcirculation blood flow and ameliorated pathological changes in the mesenteric artery and the small intestine. Furthermore, luteolin inhibited the release of pro-inflammatory cytokines, the expression of TLR4, Myd88, ICAM-1, and VCAM-1, the phosphorylation of IκB-α and NF-κB/p65 in LPS stimulated EA.hy926. Conclusions Our findings revealed that it is likely that luteolin can ameliorate microcirculatory disturbance. The inhibitory effects of luteolin on the leukocyte adhesion stimulated by LPS, which participates in the development of microcirculatory disturbance, are mediated through the regulation of the TLR4/Myd88/NF-κB signaling pathway.

Abstract
Background Ganluyin (GLY) is a famous classical prescription with a long history of use as a treatment for inflammatory conditions such as chronic pharyngitis (CP) in many parts of China. However, it has not been developed as a modern pharmaceutic and its anti-inflammatory mechanisms remain unclear. The aim of this study was to assess the anti-inflammatory efficacy of GLY and potential mechanisms in a rat model of CP. Methods The chemical profile of GLY was analyzed by HPLC-UV. We used a mouse model of ear edema and a rat model of paw edema. Specifically, xylene was used to induce edema on the surface of one ear in mice, and carrageenan was injected subcutaneously into the right hind paws of rats to induce paw edema. The paw thickness, ear weight, and ear perfusion were measured and recorded. The CP model in rats was induced by irritating the throat with 5% ammonia and was used to evaluate the therapeutic efficacy of GLY. Levels of interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor (TNF-α), and prostaglandin E2 (PGE2) were measured by ELISA in serum, and protein expression of cyclooxygenase-2 (COX-2) and nuclear factor kappa-B p65 (NF-κB p65) in the throat were detected by immunohistochemistry and Western blot to evaluate the anti-inflammatory mechanism of GLY. Hematological assays were also conducted. Results There were four flavonoids identified in GLY: naringin, neohesperidin, baicalin, and wogonoside. The oral administration of GLY showed a significant inhibitory effect on xylene-induced ear swelling and ear blood flow in mice and significantly ameliorated rat right hind paw edema at doses of 6.2 and 12.4 g/kg. Mechanistic studies found that the anti-inflammatory activity of GLY was related to the inhibition of pro-inflammatory cytokines such as IL-1β, IL-6, TNF-α, and PGE2 and that GLY reduced the expression of COX-2 and NF-κB p65 proteins in the throat, attenuated throat injury, and reduced inflammatory exudates. Hematological analysis showed that treatment with GLY prevented increases in white blood cell (WBC), neutrophil (NEUT), lymphocyte (LYMPH) and monocyte (MONO) levels. Conclusions These studies indicated that GLY has beneficial anti-inflammatory effects on CP and that it acts through reducing pro-inflammatory factors such as IL-1β, IL-6, TNF-α, and PGE2, as well as decreasing WBC, NEUT, LYMPH and MONO levels and decreasing the expression of COX-2 and NF-κB p65 proteins. These findings may lay the groundwork for further studies of GLY as a suitable candidate for the treatment of inflammatory diseases such as CP.

Abstract
Nω-nitro-L-arginine methyl ester (L-NAME), an inhibitor of nitric oxide (NO) biosynthesis, results in hypertension and liver injury. This study aimed at investigating the changes of liver lipometabonomics and exploring the underlying mechanisms of liver injury in the L-NAME-treated rats. The male Sprague-Dawley (SD) rats were treated with L-NAME (40 mg/kg, p.o.) for 8 weeks. After that, the liver, aorta, fecal, and serum were collected for analysis. The results showed that L-NAME induced hypertension and disordered the endothelial nitric oxide synthase (eNOS)-NO pathway in the treated rats. L-NAME could also increase the levels of serum total cholesterol (TC), triglyceride (TG), alanine transaminase (ALT), and aspartate transaminase (AST). The multidimensional mass spectrometry-based shotgun lipidomics (MDMS-SL) analysis showed that L-NAME could induce significant changes of the total hepatic lipids and most hepatic triglycerides, as well as fatty acid (FA). A positive correlation was found between the blood pressure and TAG. Immunofluorescence and Western-Blot experiments indicated that the L-NAME treatment significantly influenced some FA β-oxidation, desaturation, and synthesis-related proteins. The increase of intestinal inflammation, decrease of microcirculation and tight junction proteins, as well as alterations of microbial communities were observed in the L-NAME induced hypertensive rats, as well as alterations of microbial communities were notable correlation to TAG and FA species. This study demonstrated that the L-NAME-induced hypertensive rats exhibiting liver injury were the joint action of hepatic abnormal fatty acid metabolism and microcirculation disorder. Furthermore, the gut microflora, as well as the changes of FA β-oxidation (ACOX, CPT1α), desaturation (SCD-1), and synthesis (FAS) may be the potential mechanisms for abnormal fatty acid metabolism.

Abstract
Hepatocellular carcinoma (HCC) is a common malignancy worldwide with poor prognosis and high mortality. The aberrant expression or alteration of microRNAs (miRNAs) contributes to the development and progression of cancer. Studies have shown that miR-455 plays a regulatory role in the development of HCC. Therefore, in the present study, the role of miR-455 was analyzed in HepG2 cells proliferation and apoptosis using MTT and flow cytometry methods. Binding sites were predicted by bioinformatics and luciferase assay was used to verify the target relationship between miR-455 and RhoC-encoding gene RHOC. After that, the effects of miR-455 on RHOC and its product RhoC, were explored by qPCR and Western blotting. As PTEN is a key tumor suppressor gene in HCC, and Bcl-2 and Caspase 3 are important indication of apoptosis, expression levels of PTEN, Bcl2 and Caspase 3 proteins were determined in cells overexpressing RhoC. We show that miR-455 promotes HepG2 cells apoptosis and inhibits proliferation. Bioinformatics analysis and luciferase assay indicate that specific recognition sites for miR-455 are within the RhoC 3'-UTR. Luciferase activity was significantly lower in the cells co-transfected with miR-455 mimics and RhoC-WT (p < 0.01) as compared to that in control cells, pointing that RHOC gene is, indeed, targeted by miR-455. RHOC mRNA was significantly reduced after miR-455 transfection in HepG2 cells. In addition, we show that RhoC could activate the HCC cells proliferation ability and inhibit apoptosis rate (p < 0.01), and decrease expression of PTEN and Caspase 3 (p < 0.01), while upregulating levels of Bcl2. In conclusion, our study indicates that miR-455 plays a suppressive role in HCC development by targeting RhoC-encoding mRNA.

Abstract
This study aimed to investigate the antihypertensive effect and possible mechanism of Dendrobium officinale flos on hypertensive rats induced by high glucose and high fat compound alcohol. The hypertensive models were successfully made by high-glucose and high-fat diet, with gradient drinking for 4 weeks, and then divided into model control group, valsartan (5.7 mg·kg⁻¹) positive control group and D. officinale flos groups (3,1 g·kg⁻¹). After 6 weeks of treatment, the blood pressure of rats was measured regularly. After the last administration, endothelin-1 (ET-1), thromboxane B₂ (TXB₂), prostacyclin (PGI₂) and nitric oxide (NO) were tested. Endothelial nitric oxide synthase (eNOS) expression and lesion status in thoracic aorta were detected. The vascular endothelium dependent dilation of the thoracic aorta was detected by the isolated vascular loop tension test. The results showed that D. officinale flos could significantly reduce systolic blood pressure and mean arterial pressure in hypertensive rats, inhibit the thickening of thoracic aorta and the loss of endothelial cells, reduce plasma content of ET-1 and TXB₂, and increase the content of PGI₂ and NO. After long-term administration, vascular endothelium dependent dilation of the thoracic aorta was significantly increased, and could be blocked by the eNOS inhibitor (L-NAME) and increase the expression of eNOS. Therefore, D. officinale flos has an obvious antihypertensive effect on high glucose and high fat compound alcohol-induced hypertensive rats. Its mechanism may be correlated with the improvement of vascular diastolic function by protecting vascular endothelial cells, and finally resist hypertension.

Abstract
Background: Hypertension is a great global health challenge and it mostly requires drug combination therapy with the various advantages. Metoprolol (MP) and paeoniflorin are both commonly used for the treatment of hypertension. However, whether they exert synergistic effects on antihypertension or not remains unclear, especially on vascular endothelial function. Objective: The purpose of the study is to investigate the advantages of the combined antihypertensive effects of paeoniflorin enriched extract from Radix Paeoniae Alba (RE) and MP in spontaneously hypertensive rats (SHR). Materials and Methods: SHR divided into six groups (n = 8 each group), animals in each group were administrated orally with distilled water, MP (6 and 20 mg/kg), RE (30 and 90 mg/kg), and MP (6 mg/kg) combined with RE (30 mg/kg) (MP + RE), respectively, daily for 6 weeks. Blood pressure (BP) and microcirculation were assessed. The organ bath experiment and hematoxylin and eosin staining were, respectively, performed for the functional and pathological vascular function analysis. Immunohistochemistry was applied to detect endothelial nitric oxide synthase (eNOS) expression in aorta, heart, and kidney. Further, high-performance liquid chromatography was employed to quantitatively determine paeoniflorin in RE and MP + RE sample solvent, as well as in plasma of Sprague-Dawley rats (SD) after single-dose administration of them. Results: The results showed that MP + RE significantly reduced BP, increased microcirculation, improved vascular function and pathological changes, and upregulated eNOS expression. MP was also found to increase the blood concentration of paeoniflorin in SD. Conclusion: The combination of RE and MP could be used for the treatment of hypertension and could improve microcirculation, upregulate eNOS expression, and mitigate endothelial dysfunction in SHR. SUMMARY Paeoniflorin enriched extract from Radix Paeoniae Alba and metoprolol exert synergistic antihypertensive effects.

Abstract
PURPOSE The aim of this meta-analysis was to investigate preoperative plasma fibrinogen (PPF) as a prognostic marker in esophageal carcinoma (EC) by meta-analysis. METHODS Relevant studies were sought in the databases including Pubmed, Web of Science, Cochrane library, and Wanfang databases up to Oct 10th, 2017. Hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) were used as effective value, and pooled HRs were synthesized by STATA 14.0 to assess the prognostic impact of PPF on EC patients. RESULTS A total of 8 studies with 2827 patients were collected in this meta-analysis. Our results revealed that high PPF was significantly associated with poor OS (HR = 1.90, 95% CI 1.56-2.33, P = 0.000; HR = 1.76, 95% CI 1.28-2.42, P = 0.000) and poor DFS (HR = 1.91, 95% CI 1.50-2.43, P = 0.000; HR = 1.51, 95% CI 1.16-1.97, P = 0.000) in EC patients from univariate and multivariate analysis results, respectively, which suggested that EC patients with high PPF will suffer from high postoperative mortality and recurrence rate. CONCLUSION High PPF was significantly associated with poor OS and DFS in EC patients. Fibrinogen can serve as a prognostic marker and even a future targeting molecule during the treatment of EC patients.

Abstract
Epimedin C is one of the chemical markers and major flavonoids in Herba Epimedii (Yinyanghuo), which is traditionally used to treat bone diseases and gonadal dysfunction in China. Our previous study indicated that epimedin C could induce endothelial-like, but not osteogenic differentiation of C3H/10T1/2 cells in vitro. As vasculogenesis plays a pivotal role in bone formation, this study used the bone morphogenetic protein 2 (BMP2) induced ectopic bone formation model and mice 4T1 breast cancer cells co-implanted with luciferase labeled C3H/10T1/2 cells (4T1 [Formula: see text] C3H/10T1/2-Luc) model to examine the in vivo effects of Epimedin C on vasculogenesis. As a result, Epimedin C significantly increased the bone weight and blood perfusion of mice in the BMP2 induced ectopic osteogenesis model, and the bone in Epimedin C [Formula: see text] BMP2 group was more mature than that in BMP2 group. In addition, the tumor weight, blood perfusion and tumor-associated angiogenesis were also significantly increased in the Epimedin C treated 4T1 tumor bearing mice. The mRNA levels of endothelial markers, such as the platelet endothelial adhesive factor-1(CD31), the endothelial cell specific molecule-1(ESM-1), and the vascular von Willebrand factor (vWF) in mouse 4T1 mammary tumor tissue, were commonly found to occur alongside the luciferase (labeled in C3H/10T1/2 cells) expression and significantly increased after Epimedin C treatment. Taken together, Epimedin C can effectively promote vascularization both in the BMP2-depended bone formation model and in the 4T1 mammary tumor-bearing model by inducing an endothelial-like differentiation of C3H/10T1/2 in BALB/c nude mice.

Abstract
To study the relaxation effect of buddleoside combined with luteolin on aortic rings in SD rats and its mechanism. The effect of buddleoside alone(7.5×10⁻⁶g•mL⁻¹), luteolin alone(7.5×10⁻⁶g•mL⁻¹) and the combination of buddleoside and luteolin(1∶4) on norepinephrine-induced contractility of complete, endothelium-denuded, and L-NAME and indomethacin-pretreated thoracic aorta in SD rats were observed in the in vitro ring tension test. Western blot was used to detect p-Akt and p-eNOS protein expressions in the thoracic aorta. The experimental results showed that buddleoside combined with luteolin could significantly increase the relaxation rate of blood vessels and endothelium and L-NAME-pretreated vascular rings compared with the two single administrations. And buddleoside combined with luteolin could also significantly increase p-Akt and p-eNOS protein expressions.The results suggested that the combination of buddleoside and luteolin could effectively relax the blood vessel, and the mechanism may be to increase the synthesis and release of NO and reach the role of relaxing blood vessel by activating PI3K/Akt/NO signaling pathway and enhancing the activity of eNOS.

Abstract
Blood pressure variability (BPV) is associated with the development and progression of severe target organ damage (TOD). This study aims to evaluate the protective effect of paeoniflorin enriched extract from Radix Paeoniae Alba (PG) on BPV and TOD in spontaneously hypertensive rats (SHR). All SHR were orally treated with distilled water, metoprolol (MP, 20 mg/kg), and PG (PG-H, 90 mg/kg or PG-L, 30 mg/kg) for a single time or daily for 7 weeks. The 24-hour dynamic blood pressure was monitored and then calculated BPV including long- and short-term systolic blood pressure variability (SBPV), diastolic blood pressure variability (DBPV), mean blood pressure variability (MBPV), and heart rate variability (HRV) as well as the 24-hour-SBP, 24-hour-DBP, and 24-hour-MBP. The protective effects of PG on TOD were observed by histopathologic and biochemical detection. The results indicated that long- and short-term SBPV, DBPV, MBPV, and HRV as well as 24-hour-SBP, 24-hour-DBP, and 24-hour-MBP showed no significant changes after single-dose administration of PG and significantly decreased after administration with PG for 7 weeks. PG could also markedly improve the damage of aorta, heart, kidney, and brain. This study suggested that PG could notably reduce BPV, stabilize blood pressure, and mitigate TOD in SHR.

Abstract
Hypoxic in the tumor mass is leading to the myeloproliferative-like disease (leukemoid reaction) and anemia of body, which characterized by strong extensive extramedullary hematopoiesis (EMH) in spleen. As the key transcription factor of hypoxia, hypoxia-inducible factor-1 (HIF-1) activates the expression of genes essential for EMH processes including enhanced blood cell production and angiogenesis. We found ursolic acid (UA), a natural pentacyclic triterpenoid carboxylic acid, inhibited growth of breast cancer both in vivo and in vitro. The suppression was mediated through the inhibition of multiple cell pathways linked to inflammation, proliferation, angiogenesis, and metastasis. UA also suppressed the leukemoid reaction and the EMH phenomenon of the tumor bearing mice without any significant suppression on body weight (i.p. by 20 mg/kg for 28 days). This is associated with the significant decrease in white blood cells (WBC), platelets (PLT) and spleen weight. During this process, we also detected the down-regulation of cell proliferative genes (PCNA, and β-catenin), and metastatic genes (VEGF, and HIF-1α), as well as the depression of nuclear protein intensity of HIF-1α. Furthermore, the expression of E2F1, p53 and MDM2 genes were increased in UA group when the VEGF and HIF-1α was over-expressed. Cancer cells were sensitive to UA treating after the silencing of HIF-1α and the response of Hypoxic pathway reporter to UA was suppressed when HIF-1α was over expressed. Overall, our results from experimental and predictive studies suggest that the anticancer activity of UA may be at least in part caused by suppressing the cancer hypoxia and hypoxia-mediated EMH.

Abstract
INTRODUCTION Commonly encountered foreign bodies are remnants from surgical procedures and ingested materials. Rarely, the latter cause stone formation in the biliary tract. CASE HISTORY We describe a 51-year-old female who underwent choledoduodenostomy and who presented with abdominal distension caused by multiple stones in the bile ducts within the liver (hepatolithiasis) and an intact celery stalk. Hepatolithiasis was demonstrated by ultrasonography and computed tomography of the abdomen. The celery stalk was not confirmed until exploration of the biliary duct. CONCLUSIONS Here, we describe, for the first time, an intact, undigested celery stalk in the biliary tract which induced hepatolithiasis. We believe that choledochojejunostomy favoured reflux of the celery stalk from the duodenum into the biliary tract.

Abstract
OBJECTIVE To observe the effect of Polygonatum sibiricum on Yin deficiency model rats induced by long-term overload swimming. METHOD Except for the normal group, all of the remaining rats performed the long-term overload swimming for eight weeks, with five days every week and once every day, to establish the Yin deficiency model. The daily swimming time increased from 10 min to 180 min at the end of the 7th week, with the water depth of 60 cm and the water temperature at 30 degrees C. After the success of the modeling, the rats were orally administered with different doses of aqueous extracts from P. sibiricum (2.5, 10 g x kg(-1)) for eight weeks. After the final administration, their blood were collected from orbits to measure immunoglobulin A, G and M (IgA, IgG, IgM), interleukin 2 and 6 (IL-2, IL-6) and cAMP, cGMP contents in plasma General behavioral indicators (weight, facial temperature, pain threshold and holding power) of rats were observed during the drug administration. RESULT Compared with the model control group, aqueous extracts from P. sibiricum was given for eight weeks to significantly increase the rat weight and holding power of Yin deficiency model rats, decrease the facial temperature and the sensitivity of pain threshold, and increase IgA, IgG, IgM and IL-6 content and IgG content in serum, but without statistical difference. Aqueous extracts from P. sibiricum (10 g x kg(-1)) could also increase IL-2 content in serum, and decrease cAMP content and cAMP/cGMP ratio. CONCLUSION P. sibiricum could improve the general behavioral indicators (weight, holding power, pain threshold and facial temperature), immunologic functions (IgA, IgG, IgM) and cyclic nucleotide (cAMP, cAMP/cGMP), so as to ameliorate such Yin deficiency symptoms as dysphoria in chestpalms-soles, weight loss, soreness and weakness of waist and knees, immunologic dysfunction and cyclic nucleotide system disorders.

Abstract
In order to provide scientific basics for exploitation and sufficient application of Dendrobium officinale leaves resources, the phenol-sulfuric acid method was applied to determine the polysaccharide content. The monosaccharides were derivated by PMP and the derivatives were identified by HPLC-DAD-ESI-MS(n) and the contents of mannose and glucose were determined simultaneously. Similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (2004A) was employed to generate the mean chromatogram and similarity analysis of the samples was carried out. The results demonstrated that polysaccharide content, monosaccharide compositions and composition ratio had an obvious difference between stems and leaves. The polysaccharide content of stems was higher than that of leaves. Monosaccharide composition in leaf was significantly different from that in stem. The polysaccharide from stems was composed of mannose and glucose, however the polysaccharide of leaves was acid heteropolysaccharide and was mainly composed of five monosaccharides, including mannose, galacturonic acid, glucose, galactose and arabinose. The similarity value of the 14 batches was above 0.9, indicating that similarity of fingerprints among different samples was high. The study can provide evidence for expanding the medicinal parts of D. officinale.

Abstract
In order to investigate the anti-proliferative effects of triptolide (TP) on 4T1 mice breast cancer cell line in vitro and in mouse model, as well as the possible mechanisms, we detected the effect of TP on cell proliferation by MTT assay or Crystal Violet Staining in our research. Flowcytometry combined with FITC-Annexin V/PI staining were used for detecting TP induced 4T1 cell apoptosis. The protein expression of ERalpha, p-ERalpha, ERbeta, p-ERbeta, ERK, p-ERK, p38, p-p38, SAPK/JNK, and p-SAPK/JNK was tested by western blotting. We also compare TP with chemotherapy drug doxorubicin in 4T1 tumor bearing BLAB/c mice model, the Xenogen bioluminescence imaging, H&E, and IHC result indicated that TP exhibits an anticancer proliferation activity. As a result, TP in 100, 10, 1, 0.1 micromol x L(-1), all inhibited the proliferation of 4T1 cells by MTT assay and Crystal Violet Staining. TP which concentrations is 10, 1, 0.1 micromol x L(-1) could induce the apoptosis of 4T1 cells and reduce the cell proliferation. TP in 200 microg x kg(-1) could inhibit the tumor growth in vivo. The anticancer proliferation of TP was involved in its effect on reducing expression of ERalpha, p-ERalpha, ERbeta, and p-ERbeta, but nothing to do with the activation of MAPK signaling pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Flos Chrysanthemi is used in a variety of diseases in traditional Chinese medicine including hypertension, and the total flavonoids (rich in luteolin (LUT) and buddleoside (BUD)) of Flos Chrysanthemi is known to modulate vascular functions and reduce the blood pressure. However, the active flavonoids and their synergistic effects on anti-hypertension are still unclear. To investigate the combined anti-hypertension effects of LUT and BUD enriched extracts on spontaneously hypertensive rats (SHR), as well as the anti-hypertensive mechanism of LUT&BUD mixture. MATERIALS AND METHODS CODA Mouse & Rat Tail-Cuff Blood Pressure System was used to measure the systolic blood pressure (SBP) and diastolic blood pressure (DBP) of SHR after treated with extracts contains with LUT and/or BUD. The expressions of Ang II, PRA, ALD, ET, PGI2 and TXB2 were investigated by ELASA. Serum NO concentration was measured by the method of Nitric acid reductase. RESULTS A single administration of LUT, BUD, or LUT:BUD=1:1 significantly reduced SBP by about 3.35 mmHg, 4.39 mmHg and 15.42 mmHg, respectively. Chronic administration of LBM (at 60 mg/kg; p.o. for 30 days) reduced both SBP and DBP by 4.04% and 5.24% of the vehicle group, respectively. Oral administration of LBM at 60 mg/kg inhibited the serum levels of ANG, ALD and ET, but increased serum NO concentration. CONCLUSION This study shows the synergistic anti-hypertension effects of LUT and BUD in SHR. The effects of LBM on blood pressure are associated with RAAS and endothelial system. Thus, our experiments suggest that the combination of luteolin and buddleoside from Flos Chrysanthemi are potentially useful for the therapeutic treatments for hypertension.

Abstract
Morroniside, an iridoid glycoside extracted from Cornus officinalis, has multiple pharmacological effects such as neuroprotection. This study took the lead in establishing a method for determining morroniside concentration in rat plasma by high performance liquid chromatography-tandem mass spectrometry. Plasma samples were processed with protein precipitation method, with hyperoside as the internal standard. An Inertsil C8-3 column (2. 1 mm x 50 mm, 5 microm) was adopted, with a mobile phase composed of water (containing 1 mmol L-1 Sodium formate)-acetonitrile (gradient elution) at a flow rate of 0.4 mL . min -1. Electrospray ionization (ESI) was adopted in the positive ion mode for multi-reaction monitoring (MRM). Morroniside showed a good linear relationship ranging between 2-5 000 microg L-1 (r = 0. 995 7), with the minimum limit of quantification of 2 microg L-1. Its precise, accuracy, recovery and matrix effect were all in line with the biological sample measurement requirements. Therefore, the method described above was proved to be suitable for the determination of morroniside concentration in rat plasma. To use the method in the pharmacokinetic study on morroniside in rats, oral administration dose shall be set at 20 mg . kg - to map the plasma concentration-time curve. Main pharmacokinetic parameters were calculated by DAS 2. 0. Specifically, AUC0-inifinity was (587.6 +/- 290. 7) microg min L-1, Cmax was (334.2+/-148.0) microg L-1, Tmax was (0.6 +/-0.3) h, t1/2 was (0.7+/-0.3) h.

Abstract
OBJECTIVE To observe the effect of Dendrobium officinale granule (DOG) on symptoms, blood pressure and serum biochemical indexes of long-term-alcohol-induced hypertension rats. METHOD The alcohol-induced hypertension rat model was established by feeding alcohol drink to normal rats (the alcohol volume fraction increases from 5% to 22%). Since the 4th week, DOG was administered for 32 weeks, once everyday. During the experiment, body weight, kinematic parameters (locomotor activities, grip strength, duration of vertigo) and blood pressures (systolic blood pressure, diastolic blood pressure and mean blood pressure) were detected regularly. On the 28th and 32nd weeks, blood samples were collected to determine serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), uric acid (UA), creatinine (Cr), cholesterol (CH) and triglycerides (TG). RESULT (1) Sign: The DOG-administered group showed reduction in the duration of vertigo and increase in appetite, body weight, locomotor activities and grip strength. (2) Blood pressure: The DOG-administered group showed significant decrease in blood pressure since the 8th week. (3) Biochemical indexes: The DOG-administered group showed notable decrease in serum ALT, AST, ALP, Cr, UA, TG level, but without significant change in TC level. CONCLUSION The long-term administration of DOG can relieve alcohol-induced hypertension, while alleviating general signs, liver and kidney injuries and abnormal blood fat biochemical indexes.

Abstract
Plant-derived active constituents and their semi-synthetic or synthetic analogs have served as major sources of anticancer drugs. 20(S)-protopanaxadiol (PPD) is a metabolite of ginseng saponin of both American ginseng (Panax quinquefolius L.) and Asian ginseng (Panax ginseng C.A. Meyer). We previously demonstrated that ginsenoside Rg3, a glucoside precursor of PPD, exhibits anti-proliferative effects on HCT116 cells and reduces tumor size in a xenograft model. Our subsequent study indicated that PPD has more potent antitumor activity than that of Rg3 in vitro although the mechanism underlying the anticancer activity of PPD remains to be defined. Here, we investigated the mechanism underlying the anticancer activity of PPD in human cancer cells in vitro and in vivo. PPD was shown to inhibit growth and induce cell cycle arrest in HCT116 cells. The in vivo studies indicate that PPD inhibits xenograft tumor growth in athymic nude mice bearing HCT116 cells. The xenograft tumor size was significantly reduced when the animals were treated with PPD (30 mg/kg body weight) for 3 weeks. When the expression of previously identified Rg3 targets, A kinase (PRKA) anchor protein 8 (AKAP8L) and phosphatidylinositol transfer protein α (PITPNA), was analyzed, PPD was shown to inhibit the expression of PITPNA while upregulating AKAP8L expression in HCT116 cells. Pathway-specific reporter assays indicated that PPD effectively suppressed the NF-κB, JNK and MAPK/ERK signaling pathways. Taken together, our results suggest that the anticancer activity of PPD in colon cancer cells may be mediated through targeting NF-κB, JNK and MAPK/ERK signaling pathways, although the detailed mechanisms underlying the anticancer mode of PPD action need to be fully elucidated.

Abstract
This study aimed to find cytotoxic chemical constituents from Carya cathayensis leaves (LCC) by using various chromatographic procedures. Identification of the chemical constituents was carried out by various spectroscopic techniques and classical chemical methods. The cytotoxic activity of the constituents was assayed on HeLa and HepG2 cell lines by staining with 3-(4,5-dimethylthiahiazol-2-y1)-2,5-di-phenytetrazolium bromide (MTT). Six flavanoids, namely (1) pinostrobin, (2) pinostrobin chalcone, (3) wogonin, (4) cardamonin, (5) alpinetin and (6) tectochrysin were identified from this species. Compounds 2-6 were isolated from this kind of plant for the first time. MTT results showed that wogonin has a moderate cytotoxic activity with IC(50) values of 17.03 ± 2.41 and 44.23 ± 3.87 µM against HeLa and HepG2 cell lines, respectively. According to the correlation of primary the structure and activity, 8-methoxy substituent in these flavones may be a major factor of the antitumor activity.

Abstract
OBJECTIVE To establish an effective way for rapid identification of Dendrobium candidum based on DNA molecular marker. METHODS The genetic diversity among 11 wild species of Dendrobium was studied by using the random amplification polymorphism DNA. The special segment with random primer in Dendrobium candidum was recovered, cloned and sequenced. According to its sequence, a pair of specific primers was synthesized and tested for the specific detection of Dendrobium candidum. RESULTS The results of PCR showed that only a 302 bp electrophoresis band of Dendrobium candidum named DS-302 was found. According to the result of sequence analysis in the Genbank databases, no distinct comparability was found. And a specific primer was designed and used to identify Dendrobium candidum from other Dendrobium species effectively. There was a same band like DS-302 in Dendrobium candidum, but not be discovered in other species of Dendrobium. CONCLUSIONS The RAPD marker DS-302 was successfully converted into SCAR marker. It was an effective way to identify Dendrobium candidum more rapidly.

Abstract
We have previously shown that ethanol or chloroform extracts of the leaves of Impatiens balsamina (LIB) have anti-tumor activity against the human hepatocellular carcinoma cell line HepG2. The ethanol extracts were separated into five fractions according to polarity. An MTT assay indicated that two of the fractions had anti-tumor activity and that the petroleum ether fraction (PEF) was the most active. But the available quantities of both the PEF and chloroform fractions (CHF) were limited, precluding further study. The chloroform extract (CHE) shared almost all the same spots with the PEF and CHF and was plentiful enough to carry out further separations. Thus, the CHE was further separated into six sub-fractions (CHE1~6) by column chromatography. A MTT assay showed that only the CHE2 fraction had a strong tumor inhibition ratio (IC50 = 6.47±0.05 mg/L), which was superior to that of curcumin (IC50 = 13.95±0.11 mg/L). However, TLC revealed that CHE2 was not pure and still contained two more components. After further separation and purification, followed by TLC and MTT assay confirmation, the final active component was isolated and identified as 2-methoxy-1,4-naphthoquinone by m.p., UV, MS and 13C- and 1H-NMR data. This is the first report demonstrating that 2-methoxy-1,4-naphthoquinone has intensive in vitro anti-tumor activity against HepG2 cells.
