RESUMO

Duhaldea cappa, a valuable medicinal plant of genus Duhaldea in the tribe Inuleae, is predominantly found in China, Bhutan, India, Malaysia, Nepal, Pakistan, Thailand, and Vietnam. However, the genomic studies of Duhaldea cappa are limited. In this study, we successfully sequenced and assembled the complete chloroplast genome of Duhaldea cappa. The chloroplast genome is 150,819 bp in length with a 37.73% GC content. The chloroplast genome has a quadripartite structure, consisting of a large single-copy region of 82,731 bp, a small single-copy region of 18,168 bp, and a pair of inverted repeat sequences of 24,960 bp. The genome contains 133 genes. Among these genes, there are 88 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogeny reconstructed from data of the complete chloroplast genome indicated that Duhaldea cappa is closely related to Pluchea indica in the tribe Inuleae. Analyzing and reporting the chloroplast genome of Duhaldea cappa will establish a solid theoretical and data foundation for the efficient development, conservation, and utilization of this plant species.

RESUMO

Objective:This study aimed to investigate the change of the position of the tongue before and after combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion. Methods:A total of 30 children with skeletal class Ⅱ malocclusion and unobstructed upper airway were selected. The 30 children were divided into mouth-breathing group(n=15) and nasal-breathing group(n=15) and CBCT was taken. The images were measured by Invivo5 software. The measurement results of the tongue position of the two groups were analyzed by independent samples t-test. 15 mouth-breathing children with skeletal class Ⅱ malocclusion were selected for maxillary expansion and orofacial myofunctional therapy. CBCT was taken before and after treatment, the measurements were analyzed by paired sample t test with SPSS 27.0 software package. Results:The measurement of the tongue position of the mouth-breathing and nasal-breathing groups were compared, the differences were statistically significant(P<0.05). The measurement of the tongue position showed significant difference after the combined treatment of maxillary expansion and orofacial myofunctional therapy in children with mouth-breathing and skeletal class Ⅱmalocclusion(P<0.05). Conclusion:Skeletal class Ⅱ malocclusion children with mouth-breathing have low tongue posture. The combined treatment of maxillary expansion and orofacial myofunctional therapy can change the position of the tongue.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Antrodia camphorata is a genus of wood-rot basidiomycete in the family Fomitopsidaceae. It is a valuable medicinal fungus in China that contains more than 78 kinds of active compounds. A. camphorata has good protection effects on the liver, especially on alcoholic liver injury (ALI). AIM: This paper summarizes the complex occurrence and development of alcoholic liver disease (ALD). In addition, the effect of ALD on the intestine through the gut-liver axis is summarized. The protective mechanism of A. camphorata on ALI is reviewed to reveal its therapeutic potential, offering insights into future research. MATERIALS AND METHODS: A comprehensive search in the literature was obtained from books and online databases such as Web of Science, Google Scholar, PubMed, Scopus, Science direct, ACS Publications and Baidu Scholar. RESULTS: The pathogenesis of ALD mainly includes oxidative stress injury, intestinal microflora imbalance, inflammatory mediator injury and nutritional imbalance. A. camphorata contains rich active components (e.g. polysaccharides, triterpenoids, maleic and succinic acid derivatives, amino acids, superoxide dismutase, vitamins, lignin and sterols). These components have good antioxidant, anti-inflammatory and intestinal protection activities. Therefore, A. camphorata has a wide application in the prevention and treatment of ALI. CONCLUSIONS: ALD develops from a mild disease to alcoholic hepatitis and cirrhosis, which is the main reason of global morbidity and mortality. At present, there is no effective drug for the treatment of ALD. A. camphorata, as a valuable medicinal fungus unique to Taiwan, has a great protective effect on the liver. It is expected to be an effective drug for ALI treatment. Although many studies have performed the protective effects of A. camphorata on ALI, its regulatory effects on the gut-liver axis of ALD patients need to be further explored.

RESUMO

Traditional Chinese medicine (TCM) has a significant role in treating and preventing human diseases. Ischemic heart and cerebrovascular injuries are two types of diseases with different clinical manifestations with high prevalence and incidence. In recent years, it has been reported that many TCM has beneficial effects on ischemic diseases through the inhibition of apoptosis, which is the key target to treat myocardial and cerebral ischemia. This review provides a comprehensive summary of the mechanisms of various TCMs in treating ischemic cardiovascular and cerebrovascular diseases through anti-apoptotic targets and pathways. However, clinical investigations into elucidating the pharmacodynamic ingredients of TCM are still lacking, which should be further demystified in the future. Overall, the inhibition of apoptosis by TCM may be an effective strategy for treating ischemic cardio-cerebrovascular diseases.

RESUMO

Purpose: Lung cancer (LC) is the most commonly diagnosed cancer and the leading cause of cancer-related deaths. More and more long noncoding RNA (lncRNA) are associated with cancer. This study aimed to assess whether plasma lncRNA could be used to diagnose early-stage LC and identify subtypes of LC. Methods: For bioinformatic analysis, we used genetic data from the Cancer Genome Atlas, lung adenocarcinoma (LUAD), and lung squamous cell carcinoma (LUSC) datasets and a small cell lung cancer (SCLC) dataset from the Gene Expression Omnibus. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to examine the relative expression of lncRNA in LC tissues and plasma samples. The patients' clinical information was obtained at the time of sample collection. Results: According to public datasets, the lncRNA forkhead box D3 antisense 1 (FOXD3-AS1) was significantly upregulated in LUAD, LUSC, and SCLC tissues over controls. RT-qPCR assays confirmed this finding in LUAD, LUSC, and SCLC tissues and plasma samples. Even early-stage receiver operating characteristic analysis showed that plasma FOXD3-AS1 could be used to discriminate LUAD, LUSC, and SCLC from normal controls and identify LC subtypes SCLC. Conclusion: FOXD3-AS1 is significantly upregulated in LC tissues and plasma. FOXD3-AS1 could be a potential biomarker for LC subtype identification and early diagnosis.

RESUMO

Objective: To evaluate the efficacy, safety, and prognostic value of low-dose apatinib in combination with temozolomide in the treatment of primary or recurrent high-grade gliomas (HGGs). Methods: A retrospective analysis of patients with postoperative and recurrent HGGs treated in our hospital from April 1, 2018, to April 30, 2020. Patients should be treated by combination therapy (surgery + radiotherapy + chemotherapy). Patients who received apatinib combined with temozolomide chemotherapy were allocated to the research group (RG), while patients who received temozolomide chemotherapy alone were allocated to the control group (CG). The efficacy and toxic side effects were compared between the two groups. Results: There were 67 qualified patients retrieved, including 37 cases in the RG and 30 cases in the CG. There were no significant differences in objective remission rate (ORR) or disease control rate (DCR) between the control group and the study group (P > 0.05). However, the overall improvement of clinical efficacy in the observation group was better than that in the control group (P < 0.05). There was no significant difference in the incidence of adverse effects between the two groups (P > 0.05). There were no significant differences in overall survival (OS) or progression-free survival (PFS) between the two groups (P > 0.05). Conclusion: Low-dose apatinib combined with temozolomide and radiotherapy for HGGs is effective in improving efficacy, relieving brain edema, reducing the use of glucocorticoid drugs, and improving patients' quality of life. It has mild adverse effects and is well tolerated by patients.

RESUMO

Objective: To investigate the protective effect and mechanism of curcumin on intestinal barrier function in rats with enterogenic sepsis. Methods: Rats were divided into Sham group (Sham), Model group (Model), low-dose curcumin group (100 mg/kg), and high-dose curcumin group (200 mg/kg), with 10 rats in each group. Sepsis model was established in model group, low-dose curcumin group, and high-dose curcumin group. After drug intervention, hematoxylin-eosin (HE) staining was used to observe the histopathological changes of small intestine in each group. The levels of TNF-α, IL-1ß, and IL-6 in serum and intestinal tissues of rats were determined by ELISA. The expression of ZO-1, occludin, and claudin-1 in ileum was detected by QRT-PCR and Western blot. Western blotting was used to detect the expression of ERK/JNK signaling pathway, NF-κB p65, apoptosis-related proteins Caspase-3, and TNF-α in rat intestinal tissues. Results: HE staining showed that curcumin treatment reduced epithelial cell shedding, interstitial edema, and apoptosis. Compared with model group, DAO activity, serum intestinal fatty acid binding protein (I-FABP), TNF-α, IL-6, and IL-1ß expression in curcumin group were decreased in a dose-dependent manner. Curcumin can upregulate the mRNA and protein expression levels of ZO-1, occludin, and claudin-1 in ileum of CLP-induced rats. In addition, curcumin inhibits NF-κB p65 activation and apoptosis by regulating ERK/JNK signaling pathway. Conclusion: Curcumin can reduce inflammatory response and upregulate the expression of intestinal tight junction proteins ZO-1, occludin, and claudin-1 in rats with enterogenic sepsis, and protect intestinal barrier function.

RESUMO

The emergence of multidrug resistance in Neisseria gonorrhoeae is concerning, especially the cooccurrence of azithromycin resistance and decreased susceptibility to extended-spectrum cephalosporin. This study aimed to confirm the antibiotic resistance trends and provide a solution for N. gonorrhoeae treatment in Guangdong, China. A total of 5,808 strains were collected for assessment of antibiotic MICs. High resistance to penicillin (53.80 to 82%), tetracycline (88.30 to 100%), ciprofloxacin (96 to 99.8%), cefixime (6.81 to 46%), and azithromycin (8.60 to 20.03%) was observed. Remarkably, spectinomycin and ceftriaxone seemed to be the effective choices, with resistance rates of 0 to 7.63% and 2.00 to 16.18%, respectively. Moreover, the rates of azithromycin resistance combined with decreased susceptibility to ceftriaxone and cefixime reached 9.28% and 8.64%, respectively. Furthermore, genotyping identified NG-STAR-ST501, NG-MAST-ST2268, and MLST-ST7363 as the sequence types among representative multidrug-resistant isolates. Evolutionary analysis showed that FC428-related clones have spread to Guangdong, China, which might be a cause of the rapid increase in extended-spectrum cephalosporin resistance currently. Among these strains, the prevalence of N. gonorrhoeae was extremely high, and single-dose ceftriaxone treatment might be a challenge in the future. To partially relieve the treatment pressure, a susceptibility test for susceptibility to azithromycin plus extended-spectrum cephalosporin dual therapy was performed. The results showed that all the representative isolates could be effectively killed with the coadministration of less than 1 mg/liter azithromycin and 0.125 mg/liter extended-spectrum cephalosporin, with a synergistic effect according to a fractional inhibitory concentration (FIC) of <0.5. In conclusion, dual therapy might be a powerful measure to treat refractory N. gonorrhoeae in the context of increasing antibiotic resistance in Guangdong, China.

RESUMO

There have been many studies on the activities and polysaccharide production of Sanghuangporus vaninii. However, few studies have looked at triterpene production from S. vaninii using liquid-state fermentation. A method for enhancing the production of triterpenes by in situ extractive fermentation (ISEF) was studied. Eight solvents were investigated as extractants for triterpene production in the ISEF system. The results showed that using vegetable oil as an extractant significantly increased the yield of total triterpenes and biomass of S. vaninii YC-1, reaching 18.98 ± 0.71 and 44.67 ± 2.21 g/L, respectively. In 5 L fermenter experiments, the added vegetable oil improved the dissolved oxygen condition of the fermentation broth and promoted the growth of S. vaninii YC-1. Furthermore, adding vegetable oil increased the expression of fatty acid synthesis-related genes such as FAD2 and SCD, thereby increasing the synthesis of unsaturated fatty acids in the cell membrane of S. vaninii YC-1. Therefore, the cell membrane permeability of S. vaninii YC-1 increased by 19%. Our results indicated that vegetable oil increased the permeability of S. vaninii YC-1 cell membranes to promote the production of total triterpenes. The use of vegetable oil as an extractant was thus effective in increasing the yield of triterpenes in the ISEF system.

RESUMO

Cold pathogenic disease is a widespread disease in traditional Chinese medicine, which includes influenza and respiratory infection associated with high incidence and mortality. Discovering effective core drugs in Chinese medicine prescriptions for treating the disease and reducing patients' symptoms has attracted great interest. In this paper, we explore the core drugs for curing various syndromes of cold pathogenic disease from large-scale literature. We propose a core drug discovery framework incorporating word embedding and community detection algorithms, which contains three parts: disease corpus construction, drug network generation, and core drug discovery. First, disease corpus is established by collecting and preprocessing large-scale literature about the Chinese medicine treatment of cold pathogenic disease from China National Knowledge Infrastructure. Second, we adopt the Chinese word embedding model SSP2VEC for mining the drug implication implied in the literature; then, a drug network is established by the semantic similarity among drugs. Third, the community detection method COPRA based on label propagation is adopted to reveal drug communities and identify core drugs in the drug network. We compute the community size, closeness centrality, and degree distributions of the drug network to analyse the patterns of core drugs. We acquire 4681 literature from China national knowledge infrastructure. Twelve significant drug communities are discovered, in which the top-10 drugs in every drug community are recognized as core drugs with high accuracy, and four classical prescriptions for treating different syndromes of cold pathogenic disease are discovered. The proposed framework can identify effective core drugs for curing cold pathogenic disease, and the research can help doctors to verify the compatibility laws of Chinese medicine prescriptions.

RESUMO

This study aimed to investigate the protective effect of Antrodin A (AdA) from Antrodia camphorata (A. camphorata) mycelium on alcohol-induced gut microbiota and liver metabolomic disorders. In acute alcoholic liver injury mice, AdA ameliorated alcoholic exposure-induced hepatic lipid deposition (TC and TG), oxidative stress (MDA), inflammation (TNF-α, IL-1ß, IL-6, IL-17 and IFN-γ), and liver damage via modulating microbiome and metabolomic responses. AdA restored the composition of intestinal flora with an increase in the relative abundance of Lactobacillus and Dubosiella and a decrease in Clostridium_sensu_stricto_1, Lachnospiraceae_NK4A136_group, Prevotellaceae_NK3B31_group, and Prevotellaceae_UCG-001. Besides, AdA favorably regulated alcohol-induced metabolic disorders, including glutathione metabolism (S-(2-hydroxyethyl)glutathione and glutathione oxidized), ascorbate and aldarate metabolism (l-ascorbic acid), and taurine and hypotaurine metabolism (taurine). In conclusion, AdA in A. camphorata is a beneficial active ingredient to treat the microbiomic and metabolic disturbance induced by alcohol intake.

RESUMO

Armillaria mellea, also known as Hazel mushroom, is a delicious food material and traditional herbal medicine in East Asia. Protoilludane sesquiterpenoid aromatic esters from A. mellea (PSAM) are the main active components with antibacterial and anticancer activities. This study explored the antidepressant-like activities of PSAM and its possible mechanisms of action using the open field test (OFT), tail suspension test (TST) and forced swimming test (FST) in mice for the first time. The results revealed that PSAM (1 mg/kg, i.p.) exhibited markedly antidepressant-like activity, which could be reversed by pretreatment with haloperidol (a non-selective D2 receptor antagonist), bicuculline (a competitive GABA antagonist), NMDA (an agonist at the glutamate site). Meanwhile, PSAM also effectively increased the hippocampus dopamine (DA) and γ-aminobutyric acid (GABA) and decreased the hippocampus glutamate (Glu) levels of mice, indicating that the antidepressant-like effect of PSAM might be mediated by the DAergic, GABAergic and Gluergic systems.

RESUMO

Flavonoids are the main constituents of Goji berries and have good biological and pharmacological activities. The mixed-mode macroporous adsorption resins (MARs) for purification of flavonoids from Goji berries through computer-assisted calculation of the molecular size of flavonoids and the precise matching of MAR physical and chemical properties was firstly developed in the present study. Ten varieties of MARs with suitable molecular dimensions and polarities were used for investigating the adsorption/desorption behaviors of the flavonoids. Both AUKJ-1 and BWKX-1 showed higher separation efficiency than other MARs and then were mixed in different ratios to constitute a mixed-mode macroporous adsorption resin to obtain the optimal adsorption phase. Under optimal conditions, total flavonoid content of purified flavonoid (p-FLA) extract increased from 0.97% to 36.88% after one purification. The p-FLA extract from Goji berries significantly improved the expression of six genes with anti-aging effects and played an important role in aging-related Alzheimer's disease by down-regulating Aß expression.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Antrodia camphorata (A. camphorata) is a rare functional fungus in Taiwan and contains a variety of biologically active ingredients. Antrodin A (AdA) is one of the main active ingredients in the solid-state fermented A. camphorata mycelium. It protects the liver from alcohol damage by improving the antioxidant and anti-inflammatory capacity of the liver and maintaining the stability of the intestinal flora. AIM OF THE STUDY: The aim of this study was to evaluate the hepatoprotective activities of ethyl acetate layer extract (EALE), AdA, and Antroquinonol (Aq) from mycelium of A. camphorata on alcoholic liver injury. MATERIALS AND METHODS: Mice were given with intragastrically vehicle (NC, 2% CMC-Na), alcohol (AL, 12 mL/kg bw), or different A. camphorata samples (EALE, AdA, Aq) at low (100 mg/kg bw) or high (200 mg/kg bw) dosages. The positive control (PC) group was given with silymarin (200 mg/kg bw). Except the NC group, each group of mice was fasted for 4 h after the last treatment and was intragastrically administrated with 50% alcohol (12 mL/kg bw). At the end of experiment, mouse serum was collected and the liver was excised. A portion of the liver was fixed in formalin and used for histopathological analysis, whereas the rest was used for biochemical analysis and real-time PCR analysis. The intestinal flora structure of feces was analyzed by determining the v3-v4 region sequence in 16S rDNA. RESULTS: The high-dose groups of the three samples (EALEH, AdAH, and AqH) significantly alleviated the alcohol-induced increases in liver index, serum ALT, AST, and AKP activities. Serum TG level was significantly reduced in all treatment groups. The increase of HDL-C content indicated that active ingredients of A. camphorata could reduce the lipid content in serum. Furthermore, MDA contents of the AdAH and AqH groups in liver were significantly reduced, accompanying with the levels of SOD, CAT, and GSH elevated to various extents. Antioxidant and anti-inflammatory capabilities in the liver were increased in the AdAH group, as evidenced by the mRNA expression levels of Nrf-2 and HO-1 were significantly increased; while those of CYP2e1, TNF-α, and TLR-4 were significantly decreased. Analysis of intestinal flora of feces showed that alcohol treatment significantly changed the composition of intestinal flora. Supplementation with AdA could mitigate dysbiosis of intestinal flora induced by alcohol. Flora of Faecalibaculum, Lactobacillus, and Coriobacteriaceae_UCG-002 showed significantly negative correlations with ALT, AST, AKP, and MDA levels. CONCLUSION: Antrodin A could improve the antioxidant and anti-inflammatory capacities of the liver and maintain the stability of intestinal flora. It is potentially a good candidate compound against acute alcoholic liver injury.

RESUMO

Untreated landfill leachate is a threat to the environment. Here, the phosphoric acid activated biochars prepared from rice husk were successfully used for leachate treatment to achieve a high removal of color (100%), pollutants (>90%), chemical oxygen demand (∼80%) and NH4+-N (100%). The leachate treatment process on phosphoric acid activated biochar could be well described by the pseudo-second order and Langmuir isotherm model, and it was controlled by external mass transfer followed by intra-particle diffusion. The phosphorus species formed in activated biochar could adjust and control the textural properties and structures of biochar, while the phosphorus species of activated biochar could attract humic acid-like organics in the leachate via hydrogen bond and π-π interactions, which were found to significantly enhance the treatment of leachate. The findings provided important insights for efficient treatment of wastewater using agricultural waste residues on an industrial scale.

RESUMO

Vegetable waste (VW) is highly perishable and susceptible to acidification during anaerobic digestion, which inhibits biogas production. Effective process monitoring, diagnosis and control are necessary to maintain stable anaerobic digestion at a high organic loading rate (OLR). Continuous mesophilic digestion was conducted at OLRs of 0.5, 1.0, 1.5, 2.0, 3.0, 3.5 and 4.0 g volatile solids (VS)/(L d) with effluent recirculation (ER) in a reactor with total volume of 70 L. The effectiveness of three early warning indicators was validated. The ability of trace elements (TEs) (Fe, Co and Ni) to recover unstable VW digestion systems was evaluated. The results showed that the ratio of bicarbonate alkalinity (BA) to total alkalinity (TA) was a more effective warning indicator than the ratios of methane (CH4) to carbon dioxide and volatile fatty acids (VFAs) to TA. When the ratio of BA/TA was lower than 0.9, the digestion system tended to be unstable. ER maintained a stable OLR of 1.5 g VS/(L d). The addition of TEs achieved a maximum stable OLR of 3.5 g VS/(L d) with an average volumetric biogas production rate of 1.91 L/(L d). Severe VFAs accumulation and unrecoverable instability occurred at an OLR of 4.0 g VS/(L d). The supplementation of ammonium bicarbonate was not useful for the recovery of the unstable system when the OLR was greater than 3.5 g VS/(L d) for the digestion of VW. The specific methane production was approximately 340 L/kg VS during the stable period with a digestion efficiency of 85%.

RESUMO

Based on the theory of extraction and diffusion of Chinese herbal medicine, the dynamic model of ultrasonic-assisted extraction process of polysaccharide from Nostoc commune Vauch. was established according to the second law of Fick, and further verified at different solid-liquid ratio (1/40-1/80 g/mL), temperature (313.15-353.15 K), ultrasonic power (240-600 W) and extraction time (0-25 min), the dynamic parameters including rate constant and relative extraction rate were respectively analyzed. The rate constant (k) gradually increased with the increase of temperature at different solid-liquid ratio. The maximum concentration of polysaccharide (NCVP) from N. commune was obtained with an optimal extraction condition at solid-liquid ratio of 1:50, extraction temperature of 353.15 K, ultrasonic power of 540 W and extraction time of 25 min. NCVP, the non reducing sugar with typical infrared spectrum characteristics of polysaccharide, dissolves in water but not dissolved in ethanol, acetone and petroleum ether and displays a good stability and smooth surface.

RESUMO

BACKGROUND: In China, Acanthopanax sessiliflorus is a delicious wild vegetable. It is also used to treat inflammation and pain. Chiisanoside (CSS) is the main constituent of the leaf of A. sessiliflorus. Combined use of lipopolysaccharide and d-galactosamine (LPS/D-GalN) can induce acute liver failure in human beings, and there are no reports on the protective effect of CSS against LPS/D-GalN-induced acute liver injury in mice. RESULTS: Chiisanoside pretreatment evidently reduced the activities of alanine transaminase (ALT) and aspartate transaminase (AST) in the changes induced by LPS/D-GalN, and these histopathological changes induced by LPS/GalN were significantly weakened. Catalase (CAT), glutathione (GSH), and superoxide dismutase (SOD) activities increased, and malondialdehyde (MDA) activity decreased after CSS treatment compared with LPS/D-GalN treatment. Pretreatment with CSS also inhibited the expression levels of inflammatory factors. The administration of CSS prevented the phosphorylated expression of inhibitor kappa B (IκB) kinase, and led to a significant increase in heme oxygenase-1 (HO-1) expression and nuclear factor erythroid 2-related factor2 (Nrf2) nuclear translocation. CONCLUSION: The protective effects of CSS are attributed to its antioxidative effect and inflammatory suppression in Nuclear factor kappa beta (NF-κB) and Nrf2/HO-1 signaling pathways. Chiisanoside might therefore be a potential ingredient for drug and food development against acute liver injury in the future. © 2018 Society of Chemical Industry.

RESUMO

To compare the effect of integration processing technology of origin (IPTO) and traditional cutting processing technology (TCPT) of Moslae Herba for lung-Yang deficiency rats caused by complex factors, analyze the mechanism, and provide the modern pharmacology basis for the implementation of IPTO of Moslae Herba. The rat models of lung-Yang deficiency were established by smoking + swimming in ice water + drinking ice water. The model rats were randomly divided into different groups, and were treated with intragastric administration for 30 d. Then the general signs, anal temperature and autonomic activity of the rats were observed. The pathological morphology of lung tissues was observed, and the positive expression of tumor necrosis factor (TNF-α) was observed by immunohistochemical method, and the hematological indexes were determined. Enzyme linked immunosorbent assay (ELISA) method was used to detect serum nitric oxide (NO), immunoglobulin G (IGG), malondialdehyde (MDA), thromboxane B2 (TXB2) and interleukin-8 (IL-8) level, and the organ coefficients of heart, liver, spleen, lung, kidney and other organs were calculated. According to the results, Moslae Herba volatile oil and decoction could improve the general signs and autonomic activities of lung-Yang deficiency rats, improve the body weight, rectal temperature, and the content of IGG in serum of lung-Yang deficiency rats, reduce organ coefficients of heart, liver, spleen, lung and kidney, serum NO, MDA, TXB2, IL-8 contents, white blood cell and TNF-α mean optical density in the lung tissues of rats. witg statistically significant difference (P<0.01 or P<0.05). The effects of IPTO volatile oil and water decoction were slightly higher. Therefore, Moslae Herba has therapeutic effect on lung-Yang deficiency rats, and ICPT has better effect, whose mechanism may be related to the intervention of TNF-α expression, improving the level of IGG, and inhibiting NO, MDA, IL-8, and TXB2 levels.

RESUMO

The antidepressant-like effect of chiisanoside from the leaves of Acanthopanax sessiliflorus was evaluated by using mice models of depression, forced swim test (FST) and tail suspension test (TST). The results showed that treatment with chiisanoside at dose of 5.0 mg/kg significantly decreased immobility time in the FST and TST. Pretreatment with haloperidol (a non-selective D2 receptor antagonist), bicuculline (a competitive GABA antagonist) and N-methyl-D-aspartic acid (NMDA, an agonist at the glutamate site) effectively reversed the antidepressant-like effect of chiisanoside (5.0 mg/kg). Moreover, chiisanoside treatment did not change the locomotor activity. And chiisanoside (5.0 mg/kg) also effectively increased the dopamine (DA) and γ-aminobutyric acid (GABA) levels in mice brains exposed to the FST and TST in the co-treatment groups. Then we designed lipopolysaccharide (LPS)-induced antidepressant behavioral experiment, the results showed that LPS significantly increased immobility duration in the TST and FST. Chiisanoside administration could effectively reduce serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels; at the same time, the changes of related indexes of oxidative stress are improved, such as superoxide dismutase (SOD) and malondialdehyde (MDA). Moreover, chiisanoside effectively down-regulated brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB) and nuclear factor-κB (NF-κB) in hippocampal. In conclusion, chiisanoside displayed significant antidepressant-like effect, which was probably related to the DAergic, GABAergic and glutamatergic systems. And the mechanism of anti-depressant effect of chiisanoside might be via the alterations of animal behaviors, hippocampus inflammation, oxidative stress and neurotrophy, which might be attributed by the BDNF/TrkB/NF-κB pathway.
