Objective

To investigate the effect of electroacupuncture (EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt (p-Akt) protein in rat myocardium after ischemia and reperfusion.

Methods

Seventy Wistar rats were evenly randomized into seven groups: the sham operation group (group A), ischemia-reperfusion model I group (group B), ischemia-reperfusion model II group (group C), EA at Neiguan (PC 6) group (group D), EA at Ximen (PC 4) group (group E), EA at Hegu (LI 4) group (group F), and LY294002 + EA at Neiguan (PC 6) group (group G). All processes were monitored by electrocardiography. In group A, the left anterior descending coronary artery was only threaded without ligation for 100 min. In group B, the left anterior descending coronary artery was ligated for 40 min and reperfused for 60 min. The left anterior descending coronary artery in group C was ligated for 40 min and reperfused for 100 min. Groups D, E, and F received EA for 20 min before undergoing ischemia for 40 min, and then received EA for 20 min before undergoing reperfusion for 60 min. Before modeling, group G was injected with LY294002 (0.3 mg/kg) into the tail vein, and then underwent the same intervention as the other EA groups. After reperfusion, myocardial tissue from the left cardiac ventricle was collected to enable Western blot analysis of the p-Akt level, and analysis of electrocardiographic changes.

Results

In groups B and C, electrocardiography showed obvious elevation of the ST-segment II lead (ECG-STII), while the ECG-STII values were significantly lower in groups D, E, and G (P < 0.01). The p-Akt levels in groups D and E were significantly greater than those in groups B and C (P < 0.01). Compared with all other groups, group G showed a significantly different expression of p-Akt (P < 0.01).

Conclusion

The expression of p-Akt protein in cardiomyocytes was significantly greater in rats that were injected with LY294002 and received EA at Ximen (PC 4) compared with all other groups. This suggests that EA at Ximen (PC 4) resulted in activation of the phosphoinositide 3-kinase/Akt signaling pathway and phosphorylation of Akt.  相似文献

Objective

To investigate the effect of electroacupuncture (EA) of acupoints Neiguan (PC 6) and Tianquan (PC 2) on the skin temperature, blood perfusion, and alpha1- and beta2-adrenoreceptor (α1-AR and β2-AR) protein and mRNA level in rats with acute myocardial ischemia.

Methods

Thirty male adult Wistar rats [(230 ± 20) g] were randomly assigned into five groups (n = 6 each): a control group, sham operation group, model group, model group treated with EA at low frequency (L-EA, 2 Hz, 1 mA) and model group treated with EA at high frequency (H-EA, 100 Hz, 1 mA). The rat model was prepared by ligating the left anterior descending coronary artery. Electroacupuncture was performed at the left Neiguan (PC 6) for 20min daily for 3 d. After the 3rd time of the treatment, measurements of skin blood perfusion and temperature in Neiguan (PC 6) and Tianquan (PC 2) in all groups were made by laser speckle contrast imaging and infrared thermal image instrument. Real-time PCR and ELISA were used to measure mRNA level and protein level of α1-AR and β2-AR in the skin tissues of Neiguan (PC 6) and Tianquan (PC 2), respectively. Serum levels of cTnT and electrocardiogram were used to identify the state of myocardium.

Results

In the group receiving electroacupunture at Neiguan (PC 6), compared with control group, the skin temperature, blood perfusion, and β2-AR mRNA and protein level of model group significantly decreased (P < 0.05), α1-AR mRNA and protein level of model group significantly increased (P < 0.05); compared with model group, the skin temperature, blood perfusion, and β2-AR mRNA and protein level of L-EA significantly increased (P < 0.05), α1-AR mRNA and protein level of L-EA and H-EA significantly decreased (P < 0.05). The same trend has taken place in the former four groups of the Tianquan (PC 2).

Conclusion

Low-or high-frequency electroacupuncture can improve the skin temperature and blood perfusion which may be induced by decreasing the level of α1-AR and increasing the level of β2-AR of the Neiguan (PC 6) and Tianquan (PC 2) in the rat with acute myocaidial ischemia.  相似文献

METHODS

Reviewed and evaluated were all randomized clinical trials in the field of TCM in treatment of type 2 diabetes mellitus published in Chinese journals in 2012, in terms of their medication adherence, adherence measurement, and impacted factors of adherence.

RESULTS

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

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. The

Results

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

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

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

Objective

To evaluate the add-on effect of Qinbei Qingfei Yiqi (QBQFYQ) granules for ventilator-associated pneumonia (VAP) in non-infectious critically ill patients.

Methods

In this randomized controlled trial, 80 non-infectious critically ill patients undergoing mechanical ventilation in the intensive care unit (ICU) were randomly divided into two groups: those receiving QBQFYQ granules plus usual treatment (experimental group, n = 50) and those receiving only the usual treatment (control group, n = 30). The main outcome measures were VAP rate, time of VAP occurrence, duration of mechanical ventilation, and length of ICU stay. Interleukin-6 (IL-6), C-reactive protein (CRP), and T-lymphocyte (CD4+, CD8+, and CD4+/CD8+ ratio) serum levels were also evaluated before and after treatment.

Results

Compared with the control group treatment, QBQFYQ administration significantly reduced the duration of mechanical ventilation [(9.58 ± 3.14) vs (12.52 ± 4.33) days] and length of ICU stay [(14.57 ± 3.72) vs (17.82 ± 5.24) days] and delayed VAP occurrence [(4.31 ± 0.86) vs (2.43 ± 0.27) days]. Additionally, CRP and IL-6 serum levels and CD4+/CD8+ ratio were significantly lower in the experimental group (P < 0.05) than in the control group. However, there were no significant differences in hospital mortality rate (30.0% vs 33.3%) and adverse events (4.0% vs 6.7%).

Conclusion

QBQFYQ delays the time of VAP occurrence and shortens the duration of mechanical ventilation in non-infectious critically ill patients, possibly through anti-inflammatory and immunomodulatory mechanisms.  相似文献

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

Objective

The aim of this study is identify the intervention mechanism of the effects of electro-acupuncture on the expression of Ang/Tie-2 mRNA and protein in rats with acute cerebral infarction induced by middle cerebral artery occlusion (MCAO).

Methods

Altogether 120 Wistar rats were subjected to MCAO by inserting a nylon filament, and then divided into 3 groups: control group, injured group and electro-acupuncture group. The injured and electro-acupuncture groups were further divided into the following 7 subgroups according to the time after MCAO: 3, 6, 12, 24 h, 3, 7 and 12 day, with 8 rats in each subgroup. The electro-acupuncture group was given electro-acupuncture treatment at Shuigou (GV 26) instantly after operation. The rats were killed at different time points according to their groups, and then the expression levels of Ang/Tie-2 mRNA and protein were detected using Real-Time PCR and immunohistochemical staining.

Results

The mRNA and protein expression levels of Ang/Tie-2 in the electro-acupuncture group were significant higher than that in the injured group.

Conclusion

The results suggested that electro-acupuncture could significantly regulate the expression of Ang/Tie-2 mRNA and protein in the rats with acute cerebral infarction induced by MCAO, and enhance angiogenesis after ischemic penumbra.  相似文献

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

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

Objective

To determine differences in cerebral activity evoked by acupuncture and conventional stroke treatment, and identify the treatment targets.

Methods

In total, 21 patients were randomly divided into two groups. Group A (11 patients) received both acupuncture and conventional treatment, while Group B (10 patients) received conventional treatment only. Resting-state functional magnetic resonance imaging (fMRI) was performed on each participant before and after treatment. Regional homogeneity (ReHo) analysis was performed to investigate the potential mechanism of acupuncture treatment by comparing differences in cerebral activity between treatments.

Results

Group A showed higher ReHo in the frontal lobe (BA6, BA46), supra-marginal gyrus (BA40), middle temporal gyrus (BA21), cerebellum, and insula. Group B showed higher ReHo in the frontal lobe (BA6) and parietal lobe (BA3, BA7).

Conclusion

Acupuncture and conventional treatment triggered relatively different clinical efficacy and brain responses. Acupuncture treatment more significantly improved the symptoms of stroke patients. More marked changes in sensory, emotional, and motor areas (including the frontal lobe, middle temporal gyrus, cerebellum, and insula) might reflect the specific acupuncture mechanism.  相似文献

Objective

To assess skin temperature response to menstruation at acupuncture points in primary dysmenorrhea (PD) patients and healthy volunteers so as to explore acupuncture point specificity in reflecting diseases in the light of skin temperature.

Methods

Fifty-two PD patients and 49 healthy volunteers were recruited. Skin temperature measurements were performed with a skin temperature assessment device at 10 points. Absolute difference between skin temperature of the same point on the left and right side is used as main outcome measure.

Results

On the first day of menstruation, when menstrual pain attacking in PD patients, a significant increase in skin temperature difference was detected at Taixi (KI 3) compared with the healthy group (P < 0.01). A significant reduction in skin temperature difference was detected at Taixi (KI 3) in the first day of menstruation compared with those values in the third day after menstruation (P < 0.01) in the healthy group. On the third day after menstruation, a significant reduction in skin temperature difference was found at Zhongdu (LR 6) in PD group compared with the healthy group (P < 0.05). No significant differences of skin temperature were detected at other points (P > 0.05).

Conclusion

The skin temperature difference at menstruation-relevant points in PD patients did not all change significantly more than those in women without PD. Significant difference was only found in Taixi (KI 3), the Yuan-source point of Kidney meridian.  相似文献

Objective

To evaluate the clinical efficacy of Chinese medicine formula HB01 on exudative age-related macular degeneration (AMD) patients who received HB01 for 6 months by analyzing relative indexes.

Methods

From July 2006 to August 2015, 139 eligible exudative AMD patients (183 eyes) were enrolled into this study and received aqueous extract from herbs of HB01 by oral twice a day (100 mL for once) for 6 months. The best corrected visual acuity, center macular thickness (CMT), hemorrhage area, fluorescein leakage area as the main outcomes were estimated and compared before and after treatment.

Results

After 3 and 6 months of treatment, visual acuity obtained a greater improvement (P < 0.01). After 1, 3 and 6 months of treatment, CMT obviously decreased (P < 0.05). After 3 and 6 months of treatment, the hemorrhage area and fluorescein leakage area also significantly narrowed (P < 0.01). During treatment, no significant adverse events relating to HB01 treatment were elucidated.

Conclusion

On the basis of these results, HB01 could improve visual acuity, and reduce hemorrhage and fluorescein leakage of patients with exudative AMD, which may be an effective alternative and supportive treatment for exudative AMD.  相似文献

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

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

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

Objective

To evaluate the effectiveness of acupuncture analgesia (AA) compared with combined spinal-epidural anesthesia (CSEA) for labor pain relief and labor outcomes.

Methods

We evaluated 131 primiparous women who received respiratory guidance during maternal uterine contractions and received either AA (n = 43), CSEA (n = 45), or no additional treatment (control, n = 43). The groups were compared regarding visual analog scale (VAS) scores for abdominal and back pain, and labor outcomes.

Results

The abdominal VAS scores of the AA and CSEA groups were significantly lower than that of the control group. In addition, the VAS scores of the CSEA group were significantly lower than that of the AA group at 10 and 60 min after intervention. The back pain VAS scores of the AA and CSEA groups were significantly lower than that of the control group at 5, 10, and 60 min after intervention. The duration of the active phase of labor in the CSEA group was significantly longer than that of the AA and control groups. The rates of oxytocin use (4.70%), urinary retention (4.70%), and postpartum hemorrhage (273.72 ± 53.63 mL) in the AA group were significantly lower than in the CSEA group (46.70%, 24.20%, and 320.00 ± 85.60 mL, respectively).

Conclusion

Both AA and CSEA were effective for labor pain relief, CSEA provided more effective pain relief, while AA was associated with a shorter duration of labor and fewer adverse effects.and each has its advantages and disadvantages.  相似文献
