Objective
To evaluate the effects of baicalin in human gastric cancer cells, including apoptosis-inducing effects, and to investigate its underlying mechanisms of action.Methods
Cell proliferation and apoptosis assays were performed to investigate the anti-proliferation effects of baicalin in human gastric cancer BGC-823 and MGC-803 cells. Real time-quantitative polymerase chain reaction and Western blotting analysis were performed to elucidate the molecular mechanisms underlying the anti-tumor properties of baicalin.Results
In BGC-823 and MGC-803 gastric cancer cells treated with 80, 120, and 160 µmol/L baicalin for 48 h, a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay showed that baicalin significantly inhibited cell proliferation in a dose-dependent manner, while flow cytometric analysis demonstrated that baicalin could induce apoptosis, also in a dose-dependent manner. Moreover, baicalin up-regulated the expression of caspase-3, caspase-9, and B cell lymphoma (Bcl-2)-associated X protein and down-regulated the expression of Bcl-2 at both the mRNA and protein level.Conclusion
Baicalin has potential as a therapeutic agent for gastric cancer by inducing apoptosis in cancer cells. 相似文献2.

Objective
To investigate the neural differentiation capacity of water extraction of velvet antler.Methods
Velvet antler (Cervus Nippon Temminck) polypeptide (VAP) was used to differentiate neural stem cells (NSCs) towards neurons in the study. Firstly, we obtain the polypeptides of VAP by water extraction. Secondly, we observed the morphology, assayed the factors in the media by enzyme-linked immunosorbent assay, and detected the special neural molecules by immunofluorescence staining. NSCs were cultured on the cell climbing film. After neuronal differentiation, differentiated NSCs were mounted for immunocytochemistry with immunofluorescence technique.Results
The differentiating cells look like neuron, some special factors, such as Glial cell line-derived neurotrophic factor, nerve growth factor, in the media can be detected while differentiated neuron -like cells can express the special neural molecules.Conclusion
Differentiation of NSCs towards neurons can be induced by velvet antler polypeptide. 相似文献3.

Finally 124 studies were included. None studies reported the medication adherence. The factors impacting medication adherence couldn't be analyzed due to none reporting adherence.CONCLUSION
Medication adherence reporting was poor in clinical trials in TCM research. Establishing standards for adherence assessment and reporting may be one of the important steps to improve the quality of clinical studies. 相似文献4.
Objective
To evaluate the effects of tetrandrine plus arsenic trioxide on HCC1937 cells, a triple negative breast cancer cell line, and to explore possible mechanisms.Methods
The 3-(4,5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide method was used to compare the antiproliferative effects of tetrandrine, arsenic trioxide alone and tetrandrine plus arsenic trioxide on HCC1937 cells. The median-effect principle (Chou-Talalay combination index method) was used to examine the interaction between the two drugs. Flow cytometry was used to evaluate effects of treatment with tetrandrine, arsenic trioxide or the combination of both on HCC1937 cell apoptosis. Real-time polymerase chain reaction and western blotting were performed to evaluate changes in apoptosis-related gene expression and protein levels.Results
Tetrandrine and arsenic trioxide each inhibited HCC1937 cell proliferation in a dose-dependent manner. The cell inhibition rate of HCC1937 cells treated with a combination of tetrandrine and arsenic trioxide was significantly higher than with either compound alone. The two drugs produced a synergistic effect when the inhibition rate was 20%-40%. Flow cytometry results showed that treatment with the two drugs increased the proportion of apoptotic cells. In the combination treated group, caspase-3 activation and PARP cleavage were significantly higher than in the other groups. Moreover, Bcl-2 and survivin expression were decreased, whereas that of both Bid and Bax was increased.Conclusion
These findings demonstrated that tetrandrine plus arsenic trioxide had synergistic efficacy on induction of apoptosis in HCC1937 cells. 相似文献5.

Objective
To identify the constituents in Shuanghuanglian injection (SHLI) that correlate with anaphylactoid reaction.Methods
Chemical fingerprints of 10 batches SHLI samples were determined by High Performance Liquid Chromatography (HPLC), and further investigated by similarity analysis. Combined with optical microscopy, both anaphylactoid experiments and confirmatory assay were displayed in Rat basophil leukemia cells (RBL-2H3) to obtain the histamine release inducing by SHLI. The content of histamine was tested by Enzyme-Linked Immuno Sorbent Assay method. Partial least squares regression (PLSR) method and HPLC-DAD-ESI-MSn technology were conducted to analyze constituents in SHLI involving anaphylactoid reaction.Results
The results of spectrum and effect relationships showed that the eight constituents were positively correlated with anaphylactoid reaction. Among which, nearly 90% of them were identified as baicalin and rutin with PLSR and HPLC-DAD-ESI-MSn. This result was in accordance with confirmatory assay on RBL-2H3 cells.Conclusion
Baicalin and rutin from SHLI were the main constituents involving anaphylactoid reaction. 相似文献7.

OBJECTIVE
To investigate the effect of brain functional recovery decoction (BFRD) on expression of vascular endothelial growth factor (VEGF) and angiopoietin-1 (Ang-1) protein in rats with cerebral ischemia reperfusion injury, and to explore the mechanism of action of BFRD.METHODS
Using the suture-occlusion method, a Wistar rat model of focal cerebral ischemia reperfusion was established. The rats were randomly divided into treatment group, model group, and sham operation group. The treatment group was administered BFRD. In situ hybridization was used to detect VEGF mRNA expression. Immunohistochemistry was used to observe expression of Ang-1 protein.RESULTS
VEGF mRNA expression was greater in the model group compared with the sham operation group (P < 0.05); Ang-1 protein expression was more obvious in the treatment group than the model group (P< 0.05).CONCLUSION
BFRD promoted VEGF mRNA and Ang-1 protein expression in the brains of rats with cerebral ischemia, suggesting increased angiogenesis. 相似文献9.

Objective
To evaluate the in vivo antiplasmodial activity and the oral acute toxicity of the Bombax buonopozense root bark aqueous extract.Methods
The in vivo antiplasmodial activity of the root bark aqueous extract of Bombax buonopozense against early and established rodent malaria infections in chloroquine sensitive Plasmodium berghei strain in mice was investigated, and oral acute toxicity of the aqueous root bark extract of Bombax buonopozense was also evaluated in mice.Results
The findings of this study revealed significant (P < 0.05) and dose dependent decrease in parasitaemia in the parasitized groups treated with varying doses of the extract (50–200 mg/kg p.o.) in both suppressive and curative tests. There was also significant decrease in parasitaemia density in the chloroquine treated group. The aqueous extract was found no toxicity in mice and the oral LD50 was determined to be greater than 5000 mg/kg.Conclusion
Bombax buonopozense root bark aqueous extract possesses potent antiplasmodial activity and may therefore, serve as potential sources of new antimalarial agents. 相似文献10.
Objective
To investigate the effect of Sophora flavescens alkaloid (SFA) in gel form on aerobic vaginitis (AV) and the possible mechanism underlying the effects.Methods
AV rat models were prepared by intravaginal inoculation of Escherichia coli and Staphylococcus aureus. SFA gel and placebo gel were intravaginally administered. In vivo antibacterial effects, vaginal microenvironment, vaginal smears, pathological tissues of vaginas, and retention of gel in the vaginal cavity were investigated.Results
SFA gel had much higher antibacterial effect than placebo gel. SFA gel protected the vaginal mucosa from erosion of bacteria. At the same time, they inhibited the inflammatory responses, exhibiting little leukocytes and parabasal cells. Furthermore, the number of vaginal Lactobacilli remarkably increased following administration of SFA gel. However, the vaginal pH did not recover to the healthy acidic levels after treatment due to the buffering effect of gel. The gel of a fluorescent agent, Cyanine 7, showed very long retention time in the vaginal cavity, up to more than 24 h, much longer than the solutions.Conclusion
The SFA gel is a promising medicine for local treatment of AV with the advantages of anti-bacteria, protection of vaginal mucosa, increase of Lactobacilli, and long retention time in the vaginal cavity. 相似文献11.

OBJECTIVE
To investigate the effect of Yishengukang decoction on the expression of the metabolic bone markers, bone-specific alkaline phosphatase (BAP), carboxyterminal propeptide of type I procollagen (PICP), and carboxyterminal cross-linked telepeptide of type I collagen (ICTP), in cancer patients with bone metastasis.METHODS
Patients (n = 180) were divided into three groups: (a) bone metastasis patients treated with Yishengukang and pamidronate disodium injection (treatment group, n = 60); (b) bone metastasis patients treated with pamidronate disodium injection alone (control group, n = 60); (c) cancer patients without metastatic bone lesion (non-bone metastasis group, n = 60). Serum levels of the metabolic markers BAP, PICP, and ICTP were detected by enzyme-linked immunosorbent assay pre- and post-therapy.RESULTS
A significant decrease in serum BAP level was observed in the treatment group compared with the control group. However there were no significant differences in serum levels of PICP and ICTP before or after treatment compared with the control group.CONCLUSION
Yishengukang decoction combined with pamidronate disodium injection reduced serum BAP level to a greater extent that pamidronate disodium injection alone. Furthermore, the combined therapy was more beneficial in regulating imbalanced bone metabolism after bone metastasis, and may represent the molecular mechanism underpinning the effects of Yishengukang decoction. 相似文献12.
Objective
To investigate the effect of Sharbat-e-Deenar (SD) on acetaminophen (APAP)-induced hepatotoxicity in rat model.Methods
Albino rats were treated with SD at the doses of 1, 2 and 4 mL/kg, p.o. against hepatotoxicity after APAP (2 g/kg, p.o. once only) intoxication. The blood, tissue biochemical parameters and histopathological observation were performed. TheResults
APAP exposure in rats significantly increased the level of biochemical parameters such as aspartate aminotransaminase, alanine aminotransaminase, lactate dehydrogenase, serum alkaline phosphatase, bilirubin, urea and creatinine into blood circulation which were reversed towards normal by SD therapy at all doses. The tissue biochemical parameters such as lipid peroxidation, reduced glutathione, adenosine tri-phosphatase and glucose-6-phosphatase were significantly restored after SD treatment against hepatotoxity. Histological analysis confirmed that SD-treated rats significantly alleviated of liver damage and reduced lesions caused by APAP intoxication. The biochemical changes are in good correlation with the histopathological observations.Conclusion
On the basis of these results, it can be concluded that SD exerts hepatoprotective activity against APAP-induced liver injury. 相似文献13.

Objective
Our aim was to explore whether heat stress protein (HSP) 9 preferentially expresses under heat stress and affects the expression of other heat stress proteins as well as to explore the effect of HSPB9 overexpression and knockdown on apoptosis in DF-1.Methods
We used gene cloning to construct an overexpression vector of the target gene, and synthesized the target gene interference fragment to transfect the chicken fibroblast cell line. Gene and protein expression, as well as apoptosis, were detected by RT-qPCR, Western blot, and flow cytometry.Results
Chicken DF-1 cells showed an early state of apoptosis in the early stages of HSPB9 overexpression. In the later stages, as HSPB9 expression increased, the cells showed inhibition of apoptosis. When the cells were under heat stress, HSPB9 expression was much higher and earlier than the expression of HSPB1 and HSPA2. In addition, high expression of HSPB9 had a negative effect on HSPB1 and HSPA2 expression. This negative feedback decreased the percentage of early stages of apoptotic cells and promoted cell survival.Conclusion
HSPB9 expression, although rapid, is detrimental to cell survival early during its overexpression. In heat stress, HSPB9 overexpression, while inhibiting the expression of HSPA2 and HSPB1, is beneficial to cell survival. 相似文献14.

Objective
To examine the influence of cupping on the quality of life of healthy people who referred to traditional Persian medicine clinics in Tehran.Methods
All participants were examined by Traditional Persian Medicine specialists and their temperaments were determined. The area between the shoulders was cleaned, and cupping was performed with a disposable cupping glass for a few minutes. The questionnaire used in this project was the Persian version of the SF-36 questionnaire which assesses people's understanding of their health status. Before cupping and then one month after cupping, all participants were called and the questionnaires were completed again. Finally, all given data was analyzed.Results
From a total of 290 questionnaires completed in the first phase of the project, 112 patients were excluded. Ultimately, the data of 178 participants was analyzed. After one month, the quality of life score of 155 participants (88%) increased, remained unchanged for 21 participants (11.7%), and decreased for 2 participants (1.1%). Asked about possible complications from cupping, 160 participants reported no side effects (89.9%).Conclusion
Our findings suggest that cupping therapy can improve the scores of quality of life in the participants in Tehran. 相似文献16.

OBJECTIVE
To evaluate the anti-platelet aggregation effects of extracts from 31 Traditional Chinese Medicines (TCM) with the property of activating blood and resolving stasis in terms of TCM theory.METHODS
The 31 TCMs extracts were prepared using water, 90% ethanol and ethyl acetate., and the effects on anti-platelet aggregation were tested on a platelet aggregation analyzer in vitro with adenosine 5'-diphosphate, bovine thrombin and arachidonic acid (AA) as aggregation inducers, respectively. Aspirin was the positive control.RESULTS
Lots of the tested TCMs had inhibitory effects with concentration-dependent manner on platelet aggregations induced by various agonists. Especially, some of the TCMs such as Chuanxiong (Rhizoma Chuanxiong), Yanhusuo (Rhizoma Corydalis Yanhusuo) and Danshen (Radix Salviae Miltiorrhizae) showed good anti-platelet aggregation effect similar or higher than that in positive control group.CONCLUSION
The study provided scientific references that several TCMs such as Chuanxiong (Rhizoma Chuanxiong), Yanhusuo (Rhizoma Corydalis Yanhusuo) and Danshen (Radix Salviae Miltiorrhizae), possess the property of anti-platelet aggregation. 相似文献17.
Objective
To evaluate the influence of clinical pathways in the hospitals using the Traditional Chinese Medicine in treatment of stroke in terms of postoperative complications, length of stay (LOS), costs incurred during hospitalization, compared with standard medical care.Methods
Medline, Embase, China National Knowledge Infrastructure (CNKI) platforms, Wanfang databases and the Cochrane Central Register of Controlled Trials were searched. The search was performed up to August 2014. Each study was assessed independently by two reviewers. The assessment of methodological quality of the included studies was based on the Methodological index for non-randomized studies standard. Meta-analyses were performed using RevMan software, version 5.0.Results
Six studies met the study inclusion criteria and were included in the Meta-analysis for a total sample of 710 patients. The aggregate overall results showed that shorter length of stay in the clinical pathway group was observed during hospital stay was associated with the use of the clinical pathways. No significant differences were found in other effects.Conclusion
Regardless the possible limitations, our findings show that clinical pathways can significantly reduce LOS. Although there is no clear evidence that clinical pathways can reduce hospital costs, but the cost of hospitalization path group for each included study were lower than the control group. 相似文献18.

OBJECTIVE
To systematically assess the effects and safety of Sini decoction as an adjuvant therapy for patients with angina pectoris.METHODS
We searched PubMed, Excerpt Medica Database, the Cochrane library, Wanfang Database, China National Knowledge Infrastructure Database, China Science and Technology Journal Database from the date of its inception until August 1, in 2014. Available literatures were selected according to the inclusion criteria. Two reviewers finished data extraction, checked the data and assessed the methodological quality of studies, independently. The Review Manage Software 5.1.0 was used for data analysis.RESULTS
Six trials involving 453 participants were eligible. None of the trials reported the mortality due to angina pectoris. The secondary outcomes showed that Sini decoction, together with nitroglycerin when necessary, may have some effects on reducing the number of angina attacks and the amount of nitroglycerin. But in terms of reducing the duration of angina and improvement of electrocardiogram, there were no statistical differences between Sini decoction group and isosorbide dinitrate group. Only one reported that no adverse events were found.CONCLUSION
Based on this systematic review, Sini decoction can reduce the dosage of nitroglycerin, when compared with isosorbide dinitrate group. And there were no enough evidence in the papers to draw any conclusions for the safety of Sini decoction. 相似文献19.

Objective
To examine whether a combinative treatment with curcumin enhances the effects of the epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) gefitinib on cell proliferation, clonogenic capacity and apoptosis in the drug-resistant lung cancer cell line NCI-H1975, and further investigate the molecular mechanisms involved.Methods
NCI-H1975 cells were treated with curcumin and gefitinib alone or in combination, and cell proliferation, clonogenic capacity and apoptosis were examined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, clone forming experiments, and flow cytometry, respectively, while p38, extracellular regulated protein kinase (ERK)1/2, and protein kinase B (AKT) phosphorylation were examined using Western blotting.Results
Compared with the effects of either agent alone, the combination of curcumin and gefitinib had a stronger suppressive effect on proliferation and the clonogenic capacity (P < 0.05), and showed an increased ability to promote apoptosis (P < 0.05) and reduce p38, ERK1/2, and AKT phosphorylation (P < 0.05).Conclusion
Co-treatment of curcumin and gefitinib significantly improves the ability of gefitinib to inhibit cell proliferation, suppress the clonogenic capacity and enhance apoptosis in NCI-H1975 cells, and these effects are possibly mediated via a decrease in phosphorylation of proteins in downstream pathways of the epidermal growth factor receptor. 相似文献20.
