RESUMO

OBJECTIVES: To explore the effect of acupuncture and moxibustion on intestinal flora in the rats with diarrhea-predominant irritable bowel syndrome (IBS-D) based on 16S rDNA technique. METHODS: Ten rats were randomized from 58 SPF-grade male SD rats to be the blank group. The remained 48 rats were prepared to be IBS-D models by the modified method of acetic acid enema combined with binding tail-clip stress. Forty successfully-modeled rats were randomly divided into a model group, an acupuncture group, a moxibustion group and a western medication group, with 10 rats in each one. In the acupuncture group, the needle was inserted at bilateral "Zusanli" (ST 36) and remained for 15 min in each rat. In the moxibustion group, the suspending moxibustion was delivered at bilateral "Zusanli" (ST 36) for 15 min. The rats in the western medication group were given pinaverium bromide suspension (10 mL/kg) by intragastric administration. The above interventions were performed once daily for consecutive 14 days. The body mass and the score of fecal trait were compared before and after modeling, as well as after intervention in each group. Fecal water content, diarrhea index and colon transit time (CTT) were measured after modeling and intervention in the rats of each group separately. After intervention, the colonic morphology of rats in each group was observed, and using 16S rDNA technique, the intestinal flora was detected. RESULTS: After modeling, compared with the blank group, the body mass and CTT were reduced (P<0.01); fecal trait scores, fecal water contents and diarrhea index increased (P<0.01) in the other 4 groups. After intervention, the body mass and CTT of the rats decreased (P<0.01), and fecal trait score, fecal water content and diarrhea index increased (P<0.01) in the model group compared with those in the blank group. In the acupuncture group, the moxibustion group and the western medication group, when compared with the model group, the body mass and CTT were elevated (P<0.01), while fecal trait scores, fecal water contents and diarrhea index declined (P<0.01). Compared with the western medication group, fecal water content decreased in the acupuncture group and the moxibustion group (P<0.05), while CTT increased in the acupuncture group (P<0.01), the body mass increased and fecal trait score was dropped in the moxibustion group (P<0.05). The colonic mucosa structure was clear and complete, and there was no obvious inflammatory cell infiltration in the blank group. The mild interstitial edema of intestinal mucosa was presented with the infiltration of few inflammatory cells in the model group. There was the infiltration of few inflammatory cells in the mucosa of the acupuncture group, the moxibustion group and the western medication group. Compared with the blank group, the indexes of Richness, Chao1, ACE and Shannon decreased in the model group (P<0.05). Indexes of Richness, Chao1 and ACE increased in the acupuncture group and the moxibustion group (P<0.05), and the Richness index in the western medication group increased (P<0.05) when compared with those in the model group. The relative abundance of Bacteroidetes, Proteobacteria and Prevotella increased (P<0.05), and that of Firmicutes and Muribaculaceae decreased (P<0.05) in the model group compared with those in the blank group. When compared with the model group, the relative abundance of Bacteroidetes, Proteobacteria and Prevotella was reduced (P<0.05), while that of Firmicutes and Muribaculaceae increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group; and that of Actinobacteria and Bifidobacterium increased in the acupuncture group and the moxibustion group (P<0.05). Compared with the blank group, the relative abundance of lipopolysaccharide (LPS) biosynthesis was elevated (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis decreased (P<0.05) in the model group. The relative abundance of LPS biosynthesis was dropped (P<0.05), and that of folate biosynthesis, lipoic acid metabolism, zeatin biosynthesis, ubiquinone and other terpenoid quinone biosynthesis increased (P<0.05) in the acupuncture group, the moxibustion group and the western medication group compared with those of the model group. CONCLUSIONS: Either acupuncture or moxibustion can relieve the symptoms of IBS-D and protect intestinal mucosa, which may be associated with regulating the structure of intestinal flora and promoting nutrient metabolism and biosynthesis.

RESUMO

OBJECTIVE: The aim of this trial was to investigate the effect of supplementation and withdrawal of selenium-enriched kale sprouts (SeKS) on productivity and egg Se concentration of laying hens. Selenium from commercial Se-enriched yeast (SeY) was used as a comparative Se source. METHODS: One-hundred and eighty 61-week-old laying hens were randomly divided into 5 treatment groups with 4 replicates (9 hens each) in a 2×2+1 Augmented Factorial Experiment in a completely randomized design. The experimental diets were basal diet, basal diet supplemented with 0.2 and 0.4 mg Se/kg from SeKS and SeY, respectively. The 8-week feeding trial was divided into 2 periods, namely the Se supplemental period (week 1 to 4) and the Se withdrawal period (week 5 to 8). RESULTS: Productive performance, egg quality and egg Se concentration of laying hens were not affected by sources of Se (SeKS and SeY) during both, the Se supplemental and withdrawal periods. Egg production and egg Se concentration increased (p<0.05) with increasing levels of Se supplementation. The egg Se concentration increased and reached a peak 1 week after Se supplementation. However, concentration of Se in eggs of hens fed Se from both sources decreased rapidly from the second week of the Se withdrawal period to reach the same egg Se concentration of hens fed the basal diet by the fourth week of the Se withdrawal period. CONCLUSION: The efficacy of Se from SeKS on productivity and egg Se concentration in laying hens was comparable to commercial SeY. Thus, SeKS can provide an alternate organic Se source for production of Se-enriched eggs.

RESUMO

Radiation-induced brain injury is a serious complication after cranio-cerebral radiotherapy, which affects the patient's quality of life and survival. A large number of studies have shown that various mechanisms such as neuronal apoptosis, blood-brain barrier damage, and synaptic dysfunction may be related to radiation-induced brain injury. Acupuncture has an important role in clinical rehabilitation of various brain injuries. As a new type of acupuncture, electroacupuncture has the characteristics of strong control ability, uniform and long-lasting stimulation, and is widely used in clinic. This article reviews the effects and mechanisms of electroacupuncture on radiation-induced brain injury, in order to provide a theoretical basis and experimental support for reasonable clinical application.

RESUMO

Systemic lupus erythematosus (SLE) is an autoimmune disease with multiple organ involvement. There are still many limitations and individual differences in the treatment based on glucocorticoids and immunosuppressants. In recent years, more and more studies have shown that the combination of traditional Chinese medicine in the treatment of SLE has the advantages of good efficacy, low adverse reactions, and high safety. However, the exact regulatory mechanism and combined traditional Chinese medicine in the treatment of SLE are still unclear. This paper reviews the research on the mechanism of traditional Chinese medicine in the treatment of SLE from metabonomic, immune cells, lymphocyte factors and apoptosis, etc, provides ideas for exploring the mechanism of traditional Chinese medicine in the treatment of SLE with modern methods.

RESUMO

ObjectiveTo explore the mechanism of Fangji Fulingtang in the treatment of acute kidney injury (AKI) induced by ischemia-reperfusion based on network pharmacology and experimental verification. MethodActive components of Fangji Fulingtang were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and previous report and targets of these components were predicted by SwissTargetPrediction. The targets of AKI were searched from GeneCards, Online Mendelian Inheritance in Man (OMIM), the database of gene-disease associations (DisGeNET), and Therapeutic Target Database (TTD). Protein-protein interaction (PPI) network was constructed by STRING. Metascape was used for Gene Ontology (GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of core targets. Cytoscape was employed to construct the "medicinal-active component-target-disease" network and “active component-target-pathway” network. AutoDock was applied for molecular docking. Finally, animal experiment was carried out to validate the mechanism of Fangji Fulingtang in treatment of AKI. ResultA total of 137 active components and 858 targets of Fangji Fulingtang, 1 294 targets of AKI, and 267 targets of Fangji Fulingtang in the treatment of AKI were screened out. Phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), proto-oncogene tyrosine protein kinase (SRC), protein kinase B1 (Akt1), and mitogen-activated protein kinase 3 (MAPK3) were the key anti-AKI targets of Fangji Fulingtang, which were involved in 1 609 GO terms, particularly cell response to lipids, membrane rafts, and protein kinase activity, and 140 KEGG pathways such as PI3K/Akt signaling pathway, chemokine signaling pathway, and Toll-like receptor signaling pathway. Molecular docking showed that the core active components had strong binding affinity to the key targets. The hematoxylin and eosin (HE) staining results indicated that Fangji Fulingtang can significantly improve the pathological state and the serological results suggested that the levels of serum creatinine (SCr) and blood urea nitrogen (BUN) were significantly reduced. ConclusionThis study clarified the mechanism of Fangji Fulingtang in the treatment of AKI and found that Fangji Fulingtang had the multi-component, multi-target, and multi-pathway characteristics in the treatment of AKI. The result lays a foundation for further study of its specific mechanism.

RESUMO

The aim of the present study was to investigate the effects of different courses of electroacupuncture on synaptic structure and synaptic function-related proteins expression in the hippocampal CA1 region of radiation-induced brain injury mice. Sixty C57BL/6J male mice were randomly divided into control group, radiation-induced brain injury model group, 1-week electroacupuncture group (EA1), 2-week electroacupuncture group (EA2), 3-week electroacupuncture group (EA3), and electroacupuncture-control (EA-Ctrl) group. The mice in model group were exposed to X-ray irradiation (8 Gy, 10 min) to establish radiation-induced brain injury model. The mice in EA groups were acupunctured at electroacupuncture points (Baihui, Fengfu and bilateral Shenshu) for 1 week, 2 weeks and 3 weeks respectively after radiation. Immunohistochemistry was used to observe synaptic structure in hippocampal CA1 region. The expressions of brain-derived neurotrophic factor (BDNF), synapsin-1 and postsynaptic density 95 (PSD95) in the hippocampal CA1 region of each group were detected by RT-PCR and Western blotting. The results showed that the nuclear gap in model and EA-Ctrl groups was significantly decreased compared to control group, however nucleus to cytoplasm ratio was significantly increased. The synaptic cleft, postsynaptic density (PSD) thickness, the mitochondrial surface density, volume density and specific surface area were significantly reduced. Compared with model group, the nucleus to cytoplasm ratio of EA2 group was significantly decreased, the PSD thickness and mitochondrial volume density were significantly increased; the nuclear gap of EA3 group was significantly increased, nucleus to cytoplasm ratio was significantly decreased, synaptic cleft and PSD thickness were significantly increased, and the mitochondrial surface density and specific surface area were all increased significantly. In addition, compared with the control group, the gene and protein expressions of BDNF, synapsin-1 and PSD95 in the hippocampal CA1 region of the model group and EA-Ctrl group were significantly decreased. However, compared with the model group, the gene expression of synapsin-1 in EA groups was significantly up-regulated, the gene expression of BDNF in EA1 and EA2 groups was significantly up-regulated, and the gene expression of PSD95 in EA2 group was significantly up-regulated. Moreover, the protein expressions of BDNF, synapsin-1 and PSD95 of EA groups were significantly up-regulated compared with the model group. These results indicate that the synaptic structure and the expression of synaptic function-related proteins in hippocampal CA1 region were injured by radiation exposure, whereas electroacupuncture intervention can significantly improve the synaptic structure and function damage caused by radiation.

RESUMO

The present study observed the effect of Guanxin Zhitong Capsules(GXZT) on the lipotoxicity of vascular endothelial cells and investigated the mechanism of GXZT in atherosclerosis treatment. The lipotoxicity model in human umbilical vein endothelial cells(HUVECs) was induced by palmitic acid(PA) stimulation. These cells were divided into a normal control group(NC, 15% normal serum), a model group(PA, 0.6 mmol·L~(-1) PA+15% normal serum), a high-dose GXZT group(GXZT-H, 0.6 mmol·L~(-1) PA+15% GXZT-medicated serum), a medium-dose GXZT group(GXZT-M, 0.6 mmol·L~(-1) PA+10% GXZT-medicated serum+5% normal serum) and a low-dose GXZT group(GXZT-L, 0.6 mmol·L~(-1) PA+5% GXZT-medicated serum+10% normal serum). HUVECs were detected for cell viability by cell counting kit-8(CCK-8) assay, apoptosis by flow cytometry, mitochondrial membrane potential(MMP) by JC-1 labeled laser scanning confocal microscopy, and total and phosphorylated proteins of p38, ERK1/2, and JNK1/2 in the mitogen-activated protein kinases(MAPK) signaling pathway by Western blot. The phosphorylated level was calcula-ted. Compared with the NC group, the PA group showed decreased cell viability and MMP(P<0.01, P<0.01), elevated apoptosis(P<0.01), and up-regulated phosphorylated levels of p38, ERK1/2, and JNK1/2(P<0.01, P<0.01, P<0.01). Compared with the PA group, the GXZT-H, GXZT-M, and GXZT-L groups showed increased cell viability and MMP(P<0.01, P<0.01, P<0.01), reduced apoptosis(P<0.01), and down-regulated protein expression and phosphorylated levels of p38, ERK1/2 and JNK1/2 in the MAPK signaling pathway(P<0.01, P<0.01, P<0.01). In conclusion, the results suggest that GXZT functions via blocking MAPK signaling pathway to relieve the damage of HUVECs induced by PA.

RESUMO

In order to enrich the transcriptome data of Fagopyrum dibotrys plants, analyze the genes encoding key enzyme involved in flavonoid biosynthesis pathway, and mine their functional genes, in this study, we performed RNA sequencing analysis for the rhizomes, roots, flowers, leaves and stems of F. dibotrys on the BGISEQ-500 sequencing platform. After de novo assembly of transcripts, a total of 205 619 unigenes were generated and 132 372 unigenes were obtained and annotated into seven public databases, of which, 81 327 unigenes were mapped to the GO database and most of the unigenes were annotated in cellular process, biological regulation, binding and catalytic activity. Besides, 86 922 unigenes were enriched in 136 pathways using KEGG database' and we identified 82 unigenes that encodes key enzymes involved in flavonoid biosynthesis. Comparing rhizome with root, flower, leaf or stem in F. dibotrys, 27 962 co-expressed differentially expressed genes(DEGs) were obtained. Among them, 23 515 DEGs of rhizome tissue-specific were enriched into 132 pathways and 13 unigenes were significantly enriched in biosynthesis of flavone and flavonol. In addition, we also identified 3 427 unigenes encoding 60 transcription factor(TFs) families as well as four unigenes encoding bHLH TFs were enriched in flavonoid biosynthesis. Our results greatly enriched the transcriptome database of plants, provided a reference for the analysis of key enzymes involved in flavonoid biosynthesis in plants, and will facilitate the study of the functions and regulatory mechanisms of key enzymes involved in flavonoid biosynthesis in F. dibotrys at the genetic level.

RESUMO

The antitumor effect of magnoflorine (Mag), an alkaloid isolated from Coptidis Rhizoma, in gastric cancer (GC) cells has not been reported. In the study, Mag suppressed the proliferation of GC cells, but showed no influence on normal gastric cells. Mechanistically, Mag induced autophagy in GC cells, as evidenced by the up-regulated expression of LC3B-II and increased autophagosome formation. Furthermore, we found that Mag-triggered autophagic cell death was regulated by reactive oxygen species (ROS)-induced suppression of serine/threonine-protein kinases (AKT) signaling. What's more, Mag treatment led to apoptosis in GC cells through enhancing cleaved Caspase-3 and PARP expressions. In addition, up-regulated expression of p27 and p21, as well as down-regulated expression of Cyclin-A and Cyclin-B1 was detected in Mag-treated GC cells, contributing to the S/G2 cell cycle arrest. Importantly, Mag incubation resulted in a significant increase in jun N-terminal kinase (JNK) phosphorylation but not p38 and ERK1/2, which was involved in the modulation of apoptosis and S/G2 phase arrest. Moreover, ROS production was highly induced by Mag treatment, and Mag-exhibited these functions was largely dependent on the generation of ROS in GC cells. Consistently, the GC cell xenograft mouse model confirmed the anti-tumor role of Mag in vivo. Collectively, these results indicated that Mag showed anti-GC effects, which could be a potential therapeutic target for GC treatment.

RESUMO

Objective:To observe the clinical efficacy of Erxian Shengbai decoction combined with Huangqi Huang soup for leucopenia (deficiency of spleen and kidney Qi) after chemotherapy, and to investigate the regulatory effect on immune function and cytokines. Method:One hundred and fifty patients were randomly divided into control group(75 cases) and observation group (75 cases)by random number table. Patients in group got batilol tablets by oral administration for 6 weeks, 60 mg/time, 3 times/day. And the patients at stage Ⅲ or Ⅳ additionally received recombinant human granulocyte colony stimulating factor injection (rhG-CSF) for subcutaneous injection,2-5 μg·kg-1·d-1, until the count of neutrophils recovered to 5.0×109个/L (10.0×109个/L for white blood cell). In the control group shengbaikang granules were taken orally,1 bag/time,3 times/day.Patients in observation group additionally received Erxian Shengbai decoction combined with Huangqi Huangshan soup for 6 weeks, 1 doses/day. Number of peripheral blood leukocytes (WBC) and neutrophils (NEUT), time to recovery, number of infections, duration of using antibiotics, dose and duration of rhG-CSF, red blood cell (RBC) count, hemoglobin (Hb), platelets (PLT) and rate of completed chemotherapy were recorded. Scores of traditional Chinese medicine(TCM)syndrome and karnofsky performance scale (KPS) were graded before and after treatment. Levels of T lymphocyte subsets (CD3+, CD4+, CD8+ and CD4+/CD8+) , natural killer cell (NK), interleukin-2 (IL-2), IL-6, and tumor necrosis factor-α (TNF-α) were all detected. Result:In the analysis of rank sum test, to the efficacy for leucopenia in observation group was better than that in control group (Z=2.057, P<0.05). Levels of WBC, NEUT, RBC, Hb and PLT were higher than those in control group (P<0.01). Time to recovery, number of infections and duration of using antibiotics, dose and duration of rhG-CSF were all less than those in control group (P<0.01). After treatment, the recovery rate of WBC and NEUT as well as completed chemotherapy were 76.12% (51/67), 73.13% (49/67) and 92.54% (62/67) in observation group, higher than 57.35% (39/68), 52.94% (36/68) and 79.41% (54/68) in control group (P<0.01). Levels of NK, CD3+, CD4+, CD4+/CD8+ and IL-2 were all higher than those in control group (P<0.01), while levels of CD8+ , IL-6 and TNF-α were lower than those in control group (P<0.05). Conclusion:Erxian Shengbai decoction combined with Huangqi Huangshan soup can promote the recovery of WBC and NEUT, stabilize the immune function, regulate cytokines, improve the microenvironment of bone marrow hematopoiesis, improve the completion rate of chemotherapy, reduce the number of infections and the amount of rhG-CSF, relieve clinical symptoms, and stabilize the quality of life in patients with leukopenia after chemotherapy (deficiency of spleen and kidney Qi).

RESUMO

OBJECTIVE: To observe the influence of different courses of electroacupuncture (EA) intervention on recognition memory and the proliferation and differentiation of hippocampal neural stem cells in mice with radiation-induced brain injury, so as to explore its mechanisms underlying improving radiation-induced brain injury. METHODS: Se-venty 30-day old C57BL/6J mice were randomly divided into control, model and EA groups, and the latter two groups were further divided into 1 week (W), 2 W and 3 W subgroups (n=10 in the control group and each subgroup). The ra-diation-induced brain injury model was established by radiating the mouse' left head at a dose of 8 Gy for 10 min by using a radiation linear accelerator. EA (1.5 V, 2 Hz/10 Hz) was applied to "Baihui" (GV20), "Fengfu" (GV14) and bilateral "Shenshu" (BL23) for 30 min, once daily for 1, 2 and 3 weeks, respectively. The learning-cognition memory ability was detected by using novel object recognition test in an open test box to record the time for exploring a novel object (TN) and a familiar object and to calculate the recognition index (RI). The neural stem cells' proliferation and differentiation in the hippocampus tissues were evaluated by counting the number of bromodeoxyuridine (BrdU)-labeled cells, neuronal nuclei (NeuN)/BrdU-positive cells and BrdU/glia fibrillary acidic protein (GFAP)-positive cells under microscope after immunofluorescence stain. RESULTS: After modeling, the TN at 90 min and 24 h and RI of the model subgroup 3 W at 90 min and RI of the model subgroup 1, 2 and 3 W at 24 h were significantly decreased in comparison with those of the control group (P<0.01, P<0.05). Moreover, the number of BrdU-positive cells in the model subgroup 1 W and 2 W, the BrdU/NeuN double-labeled cells in the 3 model subgroups and BrdU/GFAP double-labeled cells in the model subgroup 1 W and 3 W were significantly decreased (P<0.01, P<0.05). Following EA interventions, the TN in the 3 EA subgroups at both 90 min and 24 h, and RI of EA subgroup 3 W at 90 min and EA subgroup 2 W and 3 W at 24 h were considerably increased compared with those of the corresponding 3 model subgroups (P<0.05, P<0.01). The numbers of BrdU-positive cells as well as BrdU/NeuN and BrdU/GFAP double-labeled cells were significantly increased in the 3 EA subgroups (P<0.05, P<0.01, P<0.001). CONCLUSION: EA of GV20, GV14 and BL23 can improve the recognition memory ability of mice with radiation-induced brain injury, which may be related to its effect in promoting the proliferation and differentiation of stem cells in the hippocampus.

RESUMO

The present study was aimed to investigate the effects and mechanisms of electro-acupuncture (EA) on proliferation and differentiation of neural stem cells in the hippocampus of C57 mice exposed to different doses of X-ray radiation. Thirty-day-old C57BL/6J mice were randomly divided into control, irradiation, and EA groups. The control group was not treated with irradiation. The irradiation groups were exposed to different doses of X-ray (4, 8 or 16 Gy) for 10 min. The EA groups were electro-acupunctured at Baihui, Fengfu and bilateral Shenyu for 3 courses of treatment after X-ray radiation. Immunohistochemistry was used to evaluate proliferation and differentiation of the hippocampal neural stem cell. RT-PCR and Western blot were used to detect mRNA and protein expressions of Notch1 and Mash1 in the hippocampus, respectively. The results showed that, compared with the control group, the numbers of BrdU positive cells (4, 8 Gy subgroup) and BrdU/NeuN double-labeling positive cells (3 dose subgroups) were decreased significantly in the irradiation group, but the above changes could be reversed by EA. Compared with the control group, the number of BrdU/GFAP double-labeling positive cells in each dose subgroup of irradiation group was decreased significantly, while EA could reverse the change of 4 and 8 Gy dose subgroups. In addition, compared with the control group, the expression levels of Notch1 mRNA and protein in hippocampus were up-regulated, and the expression levels of Mash1 mRNA and protein were significantly decreased in each dose subgroup of irradiation group. Compared with irradiation group, the expression levels of Notch1 mRNA and protein in hippocampus of EA group were decreased significantly in each dose subgroup, and the expression levels of Mash1 mRNA and protein were increased significantly in 4 and 8 Gy subgroups. These results suggest that irradiation affects the proliferation and differentiation of neural stem cells in hippocampus of mice, whereas EA may significantly increase the proliferation and differentiation of hippocampal neural stem cells via the regulation of Notch signaling pathway.

RESUMO

The quality control of traditional Chinese medicine provides the premise of its modernization and globalization. Currently, the dual quality control based on chemical benchmark and effect benchmark has been recognized domestically and internationally. Research efforts have lead to establishment of a series of effective quality control methods based on chemical components, medicinal properties, microscopic characteristics, material constituents and pharmacodynamic targets. In the study of quality control based on chemical benchmarks, fruitful results on fingerprints, DNA barcodes, and quality markers have been achieved. However, due to a variety of factors, such as growth period, origin, growth environment and preparation process of traditional Chinese medicine, the quality control of traditional Chinese medicine based on chemical benchmarks remains difficult to fully reflect the quality of traditional Chinese medicine. At present, there is still a dispute on how to accurately reflect the quality of traditional Chinese medicines based on chemical benchmarks. For example, the index components selected in the Chinese medicine quality standards are difficult to totally reflect all the components of Chinese medicine, and the relevance between the index components versus therapeutic effect is not yet clear. In view of the complex signal network by cascade reaction and crosstalk of multi-signaling pathways within an organism, and the coordinated regulation of multi-components and multi-targets of traditional Chinese medicine, there may be different components regulating the same signal network or situations where the amount of certain chemical components within a range is not sufficient to cause a change in the signal network. Therefore, the quality control of traditional Chinese medicine based on the effect benchmark may be a useful supplement to the quality standard of traditional Chinese medicine. This paper proposes a Q-biomarker research strategy based on the effect benchmark in order to provide a methodological reference for the quality control research of traditional Chinese medicine.

RESUMO

Objective: To study the effects of association complexes on extraction and separation behavior of mangiferin in Pingfei Decoction by low-field and high-field NMR. Methods Using the T2 relaxation time and chemical shifts value of hydrogen as index, and group DNJ-citric acid as control, the relaxation characteristrics of hydrogen in association state was analyzed by low field NMR to verify the structure of association complexes combined with high-field NMR. Results DNJ and mangiferin existed in the form of association state with larger molecular weight, which inhibited the migration of components from medicinal materials to solution and caused lower transmittance. And the T2 peak shifted to the left in the spectrum, and the chemical shift in the high field nuclear magnetic field also changed. Conclusion This experiment clarified the mechanism of the effect of presence of components on extraction and separation behavior of mangiferin and provided technical support for studying the decocting method and mechanism of Chinese herbal compound.

RESUMO

Based on the nanofiltration mass transfer model, the enhanced separation behavior of ephedrine in organic solution was studied. In the experiment, the sensitive region of ethanol concentration and pH on the rejection of ephedrine was screened out by Box-Behnken central composite experiment design. Furthermore, to analyze the separation regularity of ephedrine and organic solution, the correlation between mass transfer coefficient and concentration of organic solvent was fitted with the changed organic solution by nanofiltration mass transfer mathematical model. Experiments showed the enhanced separation behavior, the decrease in the mass transfer coefficient while the increase in ethanol concentration from 20% to 40%, MWCO at 450 and pH 6.0. Under the same conditions, the enhanced separation behavior was appeared as the solvent changed into methanol and acetonitrile, the enhanced effect was positively correlated with the concentration of the three common organic solvents, and the effect order was acetonitrile>ethanol>methanol. This study took ephedrine as an example, and explored the mechanism of nanofiltration separation in the environment of organic solution, so as to provide references for nanofiltration separation for heat-sensitive traditional Chinese medicine of alkaloid.

RESUMO

Based on the molecular sieving and solution-diffusion effect in nanofiltration separation, the correlation between initial concentration and mass transfer coefficient of three typical phenolic acids from Salvia miltiorrhiza was fitted to analyze the relationship among mass transfer coefficient, molecular weight and concentration. The experiment showed a linear relationship between operation pressure and membrane flux. Meanwhile, the membrane flux was gradually decayed with the increase of solute concentration. On the basis of the molecular sieving and solution-diffusion effect, the mass transfer coefficient and initial concentration of three phenolic acids showed a power function relationship, and the regression coefficients were all greater than 0.9. The mass transfer coefficient and molecular weight of three phenolic acids were negatively correlated with each other, and the order from high to low is protocatechualdehyde >rosmarinic acid> salvianolic acid B. The separation mechanism of nanofiltration for phenolic acids was further clarified through the analysis of the correlation of molecular weight and nanofiltration mass transfer coefficient. The findings provide references for nanofiltration separation, especially for traditional Chinese medicine with phenolic acids.

RESUMO

Objective To compare the clinical features of drug induced hepatitis caused by traditional Chinese medicines (TCM) and western medicines. Methods A total of 181 patients hospitalized with drug in-duced hepatitis between January and December 2015 were enrolled. Among the patients ,75 cases were in TCM group,66 cases in western medicine group and 40 cases in combined group(accepted both TCM and western medi-cine treatment). Liver biopsies were performed and Roussed Uclaf Causality Assessment Method (RUCAM) scores showed that all patients were with scores higher than 3. The data including gender,age,clinical manifesta-tions,physical signs,laboratory tests and image characteristics were analyzed individually. Results There was no significant difference in age,the pattern of liver injury,and the course of liver damage among the three groups (P>0.05). Anorexia was common symptom in all the three groups without any significant difference(P>0.05). Jaundice was most frequently observed in TCM group while fever was most commonly found in western medicine group,which both had significant difference(P0.05). Compared with western medicine group ,the patients in TCM group had a higher level of platelet counts ,serum levels of total bilirubin ,total bile acids(TBA)and serum iron(P<0.05), and less proportion of eosinophils and lower level alkaline phosphatase(P< 0.05). Conclusions The age,the pattern of liver injury,the course of liver damage and aminotransferase levels in patients with drug induced hepati-tis caused by TCM and western medicines were similar;however,western medicines were more likely to cause al-lergic responses and hyperbilirubinemia occurred more frequently in patients with drug induced hepatitis caused by TCM.
