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

Objective

To observe the effect of transcutaneous electroacupuncture (TEA) at Neiguan (PC 6) on refractory vomiting in critically ill patients in intensive care (ICU) setting.

Methods

Ten patients admitted in ICU and presenting vomiting refractory to one or more antiemetic drugs were prospectively included in the study. TEA was applied at acupoint of Neiguan (PC 6) during 30 min with a neuromuscular transmission monitor (single-twitch stimulation with 1 Hz at a constant current of 10 mA). Nausea and Vomiting were evaluated at the following intervals: immediately after 30 min of TEA at Neiguan (PC 6), 30 min-6h and 6–24 h. The presence of nausea and/or vomiting throughout the observational period was defined as the primary end point.

Results

The presence of nausea or vomiting throughout the observational period was 10% at the end of TEA, 40% between 30 min and 6 h, and 50% between 30 min and 24 h (P < 0.001, P = 0.01 and P = 0.03 vs pre-TEA, respectively). There were no complications or side effects related to TEA.

Conclusion

TEA at Neiguan (PC 6) seems effective in reducing refractory vomiting in the patients in ICU setting, even if larger trials are needed to define optimal modalities.  相似文献

Objective

To investigate the effect of stimulating the acupoints Feishu (BL 13) and Dazhui (GV 14) on the transdermal uptake of sinapine thiocyanate contained in a gel used for the management of asthma.

Methods

Thirty Sprague-Dawley rats were randomly divided into three equal groups using a random number table: the Feishu (BL 13) acupoint group, the Dazhui (GV 14) acupoint group, and the nonacupoint group or control group. Using microdialysis technology, preprocessed skin probes were implanted into the rats at Feishu (BL 13), Dazhui (GV 14), and a nonacupoint site. Asthma gel was then placed on the skin at Feishu (BL 13), Dazhui (GV 14) acupoints, and the nonacupoint for all groups. Dialysate was collected every 30 min for 12 h. The normalized concentration of sinapine thiocyanate in the skin was determined by high-performance liquid chromatography.

Results

The rat in vivo transdermal experiment demonstrated that the quantity-time equation showed a good linear correlation with zero-order kinetics (r > 0.99). The transdermal behavior was in accordance with the first-order rate open model in which the transdermal penetration rates and the accumulative amounts of sinapine thiocyanate in the skin at the acupoint sites were greater than those through the skin of the nonacupoint site. The systemic maximum concentration and the area under the curve of sinapine thiocyanate in the acupoint groups were significantly greater than in the nonacupoint group. A lag time was observed in both acupoint groups, but not in the nonacupoint group.

Conclusion

Stimulating the acupoints promotes the percutaneous absorption of sinapine thiocyanate and also controls its release, reducing concentration fluctuations in the blood.  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 observe the therapeutic effects of electro-acupuncture (EA) combined with psychological intervention on the symptom of somzatization or obsession and mental symptom of depression or anxiety and P50 of Auditory Evoked Potential (AEP) on internet addiction disorder (IAD).

METHODS

One hundred and twenty cases of IAD were randomly divided into an EA group, a psycho-intervention (PI) group and a comprehensive therapy (EA plus PI) group. Patients in the EA group were treated with EA. Patients in the PI group were treated with cognition and behavior therapy. Patients in the EA plus PI group were treated with electro-acupuncture plus psychological intervention. Scores of IAD, scores of the symptom checklist 90 (SCL-90), latency and amplitude of P50 of AEP were measured before and after treatment.

RESULTS

The scores of IAD after treatment significantly decreased in all groups (P < 0.05), and the scores of IAD in the EA plus PI group were significantly lower than those in the other two groups (P < 0.05). The scores of SCL-90 assembled and each factor after treatment in the EA plus PI group significantly decreased (P < 0.05). After treatment in the EA plus PI group, the amplitude distance of S1P50 and S2P50 (S1-S2) significantly increased (P < 0.05).

CONCLUSION

EA combined with PI could relieve the mental symptoms of IAD patients, and the mechanism is possibly related to the increase of cerebrum sense perception gating function.  相似文献

Objective

To evaluate the clinical efficacy and safety of five phase music therapy in patients with depression after ischemic stroke.

Methods

A total of 92 patients with post-stroke depression were randomly divided into the control group (32 cases), treatment group A (30 cases), and treatment group B (30 cases). All groups were given basic therapies for cerebral infarction. In addition, the control group was administerd 50 mg of oral sertraline hydrochloride daily, while treatment groups A and B received needling at Baihui (GV 20) plus acupoint injection at Yanglingquan (GB 34) daily; treatment group B also received music therapy derived from the five phases in Traditional Chinese Medicine theory twice daily. All treatments were administered for 5 days per treatment cycle for three cycles, with a 1 day interval between cycles. In all three groups, Hamilton's depression scale (HAMD-17) score and the activities of daily life (ADL) score were measured before and after treatment, and side effects were assessed with the Treatment Emergent Symptom Scale.

Results

The HAMD-17 score significantly decreased after treatment in all three groups, and the post-treatment reduction in HAMD-17 score was markedly greater in treatment group B than in treatment group A (P < 0.01). The ADL score significantly increased after treatment in all three groups, and the post-treatment increase in ADL score was significantly greater in treatment group B than in treatment group A (P < 0.01). The Treatment Emergent Symptom Scale score was highest in the control group, and lowest in group B, and significantly differed between the three groups (P < 0.01).

Conclusion

Five phase music therapy plus acupoint needling and acupoint injection can improve the symptoms in patients with post-stroke depression.  相似文献

Objective

To investigate the effects of warming moxibustion Tianshu (ST 25, bilateral) and Qihai (CV 6) in patients with diarrhea-dominant irritable bowel syndrome (D-IBS) by assessing predominant factors, and determining the best factor combinations and their interactions. To identify the optimal quantity of warming moxibustion Tianshu (ST 25, bilateral) and Qihai (CV 6) to achieve optimal efficacy.

Methods

An L9 (34) orthogonal design was applied to 233 confirmed subjects based on the three most influential factors and the three most frequently used levels. Nine programs were designed. Subjects were assigned to four subgroups according to age and gender; each subject underwent one of the nine programs randomly. We selected Tianshu (ST 25, bilateral) and Qihai (CV 6). The scores of symptoms and the IBS Quality of Life (IBS-QOL) were evaluated after the final treatment.

Results

After treatment, clinical symptoms of all patients were significantly improved (P = 0.001). Quality of life also improved significantly (P < 0.05). For all the participants, frequency was the dominating factor regarding symptoms (P = 0.01). Duration was the dominating factor for quality of life (P = 0.0001). The best combination for improving symptoms in 30–40-year-old male and female patients was two courses of 10 min each once a day, and for 41–50-year-old male and female patients it was three courses of 10 min (males) or 30 min (females) twice a day. The best combination for quality of life was three courses of 20 min once a day. No interaction was found between frequency and course, or frequency and duration.

Conclusion

Warming moxibustion Tianshu (ST 25, bilateral) and Qihai (CV 6) is a promising therapy for D-IBS. To acquire optimal efficacy, the three main factors (duration, frequency and treatment course) of the warming moxibustion should reach a specific quantity and be combined appropriately.  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

To assess the effectiveness and safety of Kuntai capsule and hormone replacement therapy in treatment of perimenopausal syndrome.

Methods

Articles were retrieved from the databases Cochrane Database of Systematic Reviews, PubMed, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Database. Only randomized controlled trials were included; 15 trials involving 1243 patients were identified from January 2005 to April 2015. A systemic review and Meta-analysis of publications was performed. The review was limited to randomized controlled trials that compared Kuntai capsule and hormone replacement therapy to treat perimenopausal syndrome for at least 3 months. The primary outcome assessed was the treatment efficacy at 3 months, including effective rate of Kupperman menopausal scores, Kupperman menopausal scores, and blood estradiol (E2) or blood follicle stimulating hormone (FSH) levels. Other outcomes assessed were safety or adverse events, such as gastrointestinal complaints, breast distending pain, or vaginal bleeding.

Results

Kupperman menopausal scores showed no significant difference in effective rate [odds ratio (OR): 1.05, 95% confidence intervals (CI): 0.71 to 1.55] and changes in FSH level [mean difference (MD): 2.14, 95% CI: Δ 2.36 to 6.65]. There was a significant statistical difference in Kupperman menopausal scores (MD: Δ 1.14, 95% CI: Δ 2.03 to Δ 0.25) and changes in E2 level (MD: Δ 16.41, 95% CI: Δ 18.83 to Δ 13.69). There were fewer adverse events in the Kuntai capsule group than in the hormone replacement therapy group (OR: = 0.35, 95% CI: 0.25 to 0.48, P < 0.01).

Conclusion

Compared with hormone replacement therapy, Kuntai capsule can improve perimenopausal symptoms and blood E2 levels, and reduce the incidence of adverse events.  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 evaluate the effects of Guasha therapy on the rating of perceived exertion (RPE) scale score, and heart rate variability (HRV).

METHODS

A randomized controlled trial of Guasha (skin scraping) was compared with a sham scraping group and control group. Sixteen sessions within an 8-week period were completed. Sixty-five male weightlifters who had undergone normal weightlifting training for a mean of 5 years before study commencement were recruited. The RPE scale score of “snatch”, “clean and jerk” maneuvers (85% of one-repetition maximum), and HRV were measured before and after the intervention.

RESULTS

The RPE scale score for snatch, clean and jerk were reduced significantly after intervention in the Guasha group and sham group. However, there was a significant difference in the low frequency (LF) domain and LF/high frequency (HF) ratio (P < 0.05): the LF domain decreased, and the LF/HF ratio decreased.

CONCLUSION

Guasha could be used to reduce the RPE scale score, and increase the response to HRV. Guasha could be considered as an alternative to some types of recovery from sports training.  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 evaluate the clinical efficacy and safety of Heyan Kuntai capsule (HYKT) in treating women with infertility caused by diminished ovarian reserve (DOR).

Methods

One hundred eight eligible patients from three Chinese hospitals were randomly divided into an HYKT treatment group (n = 55) ora dehydroepiandrosterone (DHEA) treatment group (n = 53). Patients in the HYKT group were treated orally with four 0.5 g HYKT three times a day; patients in the DHEA group were treated with one 25.0 mg DHEA capsule three times a day. All patients were treated for 3 months and followed up over a 3-month period.

Results

Of 108 patients, 12 dropped out: six from the HYKT group, and six from the DHEA group. Eleven patients got pregnant during the treatment. Serum anti-Müllerian hormone levels and antral follicle counts increased significantly in both groups after treatment (P < 0.05) especially in the HYKT group (P < 0.05). Serum follicle stimulating hormone (FSH) levels and FSH/luteinizing hormone ratios decreased (P < 0.05) with no significant difference between the two groups. Estradiol levels in the HYKT group and DHEA-sulfate levels in the DHEA group both increased (P < 0.05). The spontaneous pregnancy rates were 12% and 11% in the HYKT and DHEA groups, respectively (not significant). During the follow-up period, 16 patients in the HYKT group underwent in vitro fertilization-embryo transfer (IVF-ET) and the number of retrieved oocytes was (5.1 ± 1.8). In DHEA group, 20 patients underwent IVF-ET and the number of retrieved oocyte was (4.2 ± 1.9) (not significant); clinical pregnancy rates were 38% in the HYKT group and 20% in DHEA group (not significant). No significant adverse reactions were observed.

Conclusion

HYKT can improve the ovarian reserve and hormone levels in patients with infertility caused by DOR. Pregnancy rates after HYKT treatment were similar to those of DHEA treatment. HYKT might be an alternative to the treatment of infertility caused by DOR.  相似文献

Objective

To investigate the possible advantages of acupotomy over sodium hyaluronate injection for the treatment of knee osteoarthritis (KOA).

Methods

Twenty rabbits were divided randomly into four groups (n = 5 in each): a control group, model group, acupotomy group, and sodium hyaluronate injection group. The model, acupotomy, and sodium hyaluronate groups underwent anterior cruciate ligament transection plus partial medial meniscectomy. Sodium hyaluronate injection and acupotomy were administered to the respective groups from weeks 5 to 8, and samples of the tibial plateau and medial condyle of the femur were collected in week 9. Vascular endothelial growth factor (VEGF) expression was assessed in cartilage and subchondral bone by immunohistochemical staining.

Results

Articular cartilage degeneration was less pronounced in the acupotomy compared with the model and sodium hyaluronate groups. VEGF expression levels in cartilage and subchondral bone were increased in the model group compared with the control group (P < 0.01), and acupotomy had a more pronounced therapeutic effect than sodium hyaluronate injection (P < 0.01).

Conclusion

Acupotomy and sodium hyaluronate injection may both reduce degeneration in the cartilage and subchondral bone in KOA based on the results from a rabbit model, but acupotomy improved the histopathology and reduced the VEGF content more effectively than sodium hyaluronate injection, probably by reducing venous stasis and intraosseous pressure. Acupotomy may improve KOA by lowering VEGF.  相似文献

Objective

To evaluate the efficacy of Xielikang capsules (XLKC) in the treatment of HIV-related diarrhea (HRD) and its effect on the plasma concentration of interleukin-17 (IL-17).

Methods

This was a randomized, open-label, positively-controlled clinical trial. Sixty-seven HRD patients were randomly assigned to two groups: one group was treated with XLKC (n = 35), the other with diosmectite (Smecta®, n = 32). All patients were treated for 4 weeks. The HRD symptom scores were evaluated in each patient based on the frequency of diarrhea, and the quality and shape of the stool according to the Chinese Medicine Clinical Treatment of AIDS Program. The plasma concentration of IL-17 before and after treatment was measured with ELISA.

Results

Compared with the Smecta® group, the XLKC group had a significantly reduced frequency of diarrhea and HRD symptom score regarding the quality and shape of stools (P < 0.05). The IL-17 concentration in the peripheral blood of the XLKC group was significantly increased after treatment, while the IL-17 concentration in the Smecta® group significantly decreased after treatment.

Conclusion

XLKC improves the symptoms of patients with HRD, and increases the plasma concentration of IL-17.  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 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
