OBJECTIVE

To investigate the effect of Sini decoction on rats with myocardial fibrosis induced by banding the abdominal aorta, and explore the mechanism underlying its actions on angiotensin II (Ang II), transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF).

METHODS

Forty-eight male Sprague-Dawley rats were randomly divided into sham operation, model, Captopril, and Sini decoction groups. The models were established by the partial banding of the abdominal aorta according to Doering's method. Eight weeks later, heart weight indexes were calculated; hemodynamic changes of the hearts were tested; changes in myocardial tissue morphology were observed by Masson staining; and myocardial collagen volume fraction was calculated. Enzyme-linked immunosorbent assay was used to measure the concentration of Ang II in serum. The expression of TGF-β1 and CTGF were determined by immunohistochemistry and Western blotting.

RESULTS

Compared with the sham operation group, the heart weight index, collagen volume fraction of the myocardium, serum levels of Ang II, and the expression of myocardial TGF-β1 and CTGF in the model group were significantly increased (P < 0.05). Compared with the model group, the heart weight index, collagen volume fraction of the myocardium, serum levels of Ang II, and the expression of myocardial TGF-β1 and CTGF in all treatment groups were significantly reduced (P < 0.05).

CONCLUSION

Sini decoction reduced Ang II level and inhibited the expression of myocardial TGF-β1 and CTGF, which may explain the mechanism of its protective effect on myocardium with fibrosis.  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 investigate a possible mechanism for protective effects of a decoction of the Qinggan Lishui formula (QF) on retinal ganglion cells (RGCs) in a rat model of microbead-induced chronic intraocular hypertension (COH).

METHODS

The COH model was generated by injecting microbeads (superparamagnetic iron oxide) into the anterior chamber of rat eyes. QF was given by intragastric administration (gavage) once daily at a dose of 6.2 g/kg until day 28, following microbead injection. Cholera toxin B subunit (CTB) retrograde labeling and immunohistochemistry were used to evaluate changes in the number of RGCs in the retina. Terminal dUTP nick end labeling (TUNEL) staining was used to assess apoptotic changes in RGCs.

RESULTS

Microbead injection induced a steady increase in intraocular pressure (IOP) of rats. Elevated IOP resulted in a progressive reduction in the number of CTB-labeled RGCs, 2-4 weeks after microbead injection. QF administration may moderately reduce IOP in the rat COH model and attenuate reduction of the number of CTB-labeled RGCs in COH rats. Furthermore, elevated IOP resulted in a progressive increase in the number of TUNEL-positive RGCs, 2–4 weeks after microbead injection, suggestive of an increase in the extent of RGC apoptosis. There was a significant reduction in the number of TUNEL-positive signals in QF-treated COH retinas, compared with untreated COH retinas.

CONCLUSION

QF decoction may provide a protective effect for RGCs in COH retinas by reducing RGC loss; these effects may be mediated by inhibition of RGC apoptosis.  相似文献

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

OBJECTIVE

To investigate the “real world” effectiveness of Traditional Chinese Medicine (TCM) in patients with acute myocardial infarction suffering from diabetes mellitus (AMI+DM patients).

METHODS

This was a retrospective cohort study. During hospitalization, the “exposure group” was defined as patients who had a TCM injection for ≥ 7 d. During follow-up, the definition of the exposure group was application of a Chinese patent medicine or decoction of Chinese medicine for ≥ 28 d. General information (age, sex, contact details), TCM use and endpoint events of AMI + DM patients during hospitalization and follow-up were collected. The correlation between TCM and the end-point events of AMI + DM patients was analyzed using a multiple logistic regression method.

RESULTS

A total of 479 AMI + DM patients were enrolled and 345 cases were followed up. During hospitalization, TCM, age, hypertension and use of an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) were associated with cardiac death. During follow-up, TCM was associated with cardiac death. TCM was a relevant factor for a composite endpoint of re-infarction and stroke. TCM, anti-thrombotic therapy and lipid-lowering therapy were related to acute heart failure. TCM, anti-thrombotic therapy, anti-MI therapy and ACEI/ARB use exhibited a strong correlation with re-hospitalization due to cardiovascular disease.

CONCLUSION

TCM reduced the prevalence of cardiac death during hospitalization, and cardiac death, a composite endpoint of re-infarction and stroke, acute heart failure and re-hospitalization due to cardiovascular disease during follow-up.  相似文献

OBJECTIVE

To investigate the effects of Shenqi Yangxin decoction (SQYXD) on heart function in a rat model of dilated cardiomyopathy (DCM) and its potential mechanisms.

METHODS

Sprague-Dawley rats were randomly divided into normal (10 rats) and DCM (150 rats) groups. DCM was induced by an intraperitoneal injection of adriamycin. Then, DCM baseline group was randomly selected sixteen DCM rats. The remaining DCM rats were randomly divided into DCM control, perindopril, metoprolol, and SQYXD groups. Cardiac function and histological analysis plus biochemical measurement of serum levels of brain natriuretic peptide (BNP), and inflammatory factors were measured. The mRNA and protein expression levels of high-mobility group box 1 (HMGB1), Toll-like receptor 4 (TLR-4), receptor for advanced glycation end products (RAGE), and nuclear factor-κB (NF-κB) were determined. Myocardial metabolism imaging was performed on the normal, SQYXD and DCM control groups to evaluate the effectiveness of treatments.

RESULTS

Rats in the DCM control group exhibited dilated left ventricular diameter, impaired cardiac function, disorganized sarcomere, impaired glucose metabolism, increased heart weight index, and increased levels of BNP, which were improved by treatment with SQYXD. In addition, hearts from rats in the DCM baseline group exhibited significantly higher levels of HMGB1, TLR-4, RAGE, NF-κB, tumor necrosis factor-α, interleukin-1, interleukin-6, interleukin-10, compared with the normal group. Interestingly, the mRNA level of HMGB1 in the DCM baseline group was positively correlated with that of TLR-4, RAGE, NF-κB, BNP, and LVEDD, but negatively correlated with LVEF. SQYXD inhibited the upregulation of HMGB1 expression and its downstream inflammatory factors.

CONCLUSION

Shenqi Yangxin decoction effectively reduced the dilated left ventricular diameter and improved heart function in dilated cardiomyopathy. The mechanisms underlying the action on DCM involve regulating the gene and protein expression of HMGB1 and its inflammatory signal pathways in the DCM rat model.  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 determine the mitigating effects of sodium 4-phenylbutyrate (4-PBA) on high-fat diet (HFD)-induced spermatogenesis dysfunction.

Methods

Male rats (n = 30) were randomly divided into three groups: control, HFD, and 4-PBA (HFD+4-PBA). After 13 weeks, rats were euthanized. Testes and epididymis were harvested for further analysis. Sex hormones were detected, and hematoxylin and eosin staining was performed to examine the histological changes in the testes. Semen samples were collected to evaluate sperm quality. Spermatogenic cell apoptosis was detected by TUNEL assay.

Results

Compared with the control group, the final body weight and body weight gain were significantly higher in HFD-fed rats, while the testicle/body weight ratios were lower (P < 0.05). In HFD-fed rats, obvious pathological changes in the testicular tissue were observed. Treatment with 4-PBA attenuated HFD-induced histological damage, ameliorated the HFD-induced decrease in serum testosterone (T), and reduced the rate of testicular cell apoptosis (P < 0.05) in obese male rats. Finally, 4-PBA significantly improved semen parameters in HFD rats (P < 0.05).

Conclusion

HFD exposure induced detrimental effects on spermatogenesis, semen quality, serum T level, and testicular cell apoptosis in rats. Treatment with 4-PBA ameliorated HFD-induced impaired spermatogenesis via inhibition of apoptosis in rats. 4-PBA may have therapeutic value in the treatment of obesity-related impairment of spermatogenesis.  相似文献

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

OBJECTIVE

To investigate the effect of acupuncture at acupoint of Shenshu (BL 23) in ovariectomized rats and sham-operated rats.

METHODS

Female Sprague-Dawley rats were divided into the following four groups (n = 12 each): sham operation only (Sham), sham operation with acupuncture (Sham + ACP), ovariectomy only (OVX), and ovariectomy with acupuncture (OVX + ACP). Operations were performed at the 9th week of age. Acupuncture of Shenshu (BL 23) was started at the 11th week of age and conducted 3 times per week until the 26th week of age.

RESULTS

Among ovariectomized rats, the acupuncture-treated rats had significantly lower body weights and cross-linked N-telopeptide of type 1 collagen levels in the urine after 3 weeks of acupuncture treatment, higher bone mineral density of the lumbar vertebra after 7 weeks, and smaller trabecular separation of the sixth lumbar vertebra, measured by micro-computed tomography, after 17 weeks than control rats. These effects were not observed in sham-operated rats. Blood concentrations of estradiol were significantly higher in the OVX + ACP group than in the untreated group. Acupuncture treatment increased plasma testosterone levels in sham-operated rats, while this increase was not observed in OVX rats.

CONCLUSION

Acupuncture of Shenshu (BL 23) prevents bone loss and structural changes by suppressing bone resorption.  相似文献

Objective

To evaluate the effect and safety of the press-needle on chronic heart failure.

Methods

According to the inclusion criteria and exclusion criteria, we screened 60 inpatients with chronic heart failure, from the Department of Cardiology in the Traditional Chinese Medicine Affiliated Hospital of Southwest Medical University, 60 cases were randomly divided into treatment group (n = 30) and control group (n = 30) in accordance with the random number table. The control group received standard Western Medicine treatment (according to the Chinese guidelines for the diagnosis and treatment of heart failure 2014 and patients' condition). The treatment group received the press-needle treatment on the basis of standard Western Medicine treatment, both treated for 3 months. Observing the 6 min walking distance (6 MWD), the score of Minnesota living with heart failure questionnaire (MLHFQ), N-terminal pro-brain natriuretic peptide (NT-proBNP), angiotensin II (Ang II), left ventricular ejection fraction (LVEF) before and after treatment.

Results

No statistical differences were found between control group and treatment group at baseline. Through self-matching test before and after treatment, the observation indexes were improved (P < 0.05). When compared with control group, 6MWD increased, the MLHFQ, NT-proBNP, Ang II decreased in treatment group, and the difference was statistically significant (P < 0.05). There was no significant difference between the two groups regarding to LVEF (P > 0.05).

Conclusion

The treatment of press-needle can significantly improve exercise tolerance and quality of life of patients with chronic heart failure, but the improvement of left ventricular ejection fraction was not significant.  相似文献

OBJECTIVE

To investigate changes in gene expression profiles in the hypothalamus related to the effects of acupuncture at the Renying (ST 9) acupoint in spontaneously hypertensive (SH) rats.

METHODS

We randomly divided 18 SH rats into Renying (ST 9) group and model control group, 9 body weight-matched Wistar-Kyoto rats were used as blank controls. Acupuncture was performed manually for 20-min daily over 28 d in the Renying (ST 9) group. Rat Gene 2.0 array technology was used for the determination of gene expression profiles and the screened key genes were verified by real-time quantitative polymerase chain reaction (RT-PCR) analyses.

RESULTS

The different groups exhibited differential gene expression: compared with the blank control group, 48 genes were up-regulated and 91 genes were down-regulated in the model group; compared with the model group, 79 genes were up-regulated and 80 genes were down-regulated in Renying (ST 9) group. The RT-PCR results of the key genes including Chi3l1, Ephx2, Klk1, 5-HT1A and Cbs were consistent with that of gene chip analysis.

CONCLUTION

Acupuncture at Renying (ST 9) could significantly lower the blood pressure of SH rats and affect their hypothalamic gene expression profile. Genes associated with the contraction of vascular smooth muscle and the regulation of inflammation, neurotransmitters may be involved in acupuncture's antihypertensive mechanism.  相似文献

Objective

To evaluate the effect of decoction prepared with Yang-activating and stasis-eliminating medicinals from Traditional Chinese Medicine (TCM) on the intestinal mucosal permeability in rats with ulcerative colitis induced by dextran sulfate sodium (DSS).

Methods

Totally 55 male Wistar rats (body weight of 170–190 g) were randomly divided into the blank group (n = 10) and the model duplication group (n = 45). The blank group was not intervened, while the other was modeled with 5% dextran sulfate sodium by gavaging in a dosage of 4 mL per day to induce ulcerative colitis, a total of 7 days. Then, the model rats were divided into model blank group, mesalazine group and TCM group, and each group was consisted of 15 rats. They were given retention enema 10 min with normal saline, mesalazine enema (0.036 g/mL), and Yang-activating and stasis-eliminating decoction [0.54 g/mL of a decoction boiled by Puhuang (Pollen Typhae), Xiebai (Bulbus Allii Macrostemonis) and Wulingzhi (Faeces Trogopteri)] for 10 days respectively. Afterwards, all of the rats were evaluated by disease activity index (DAI), histological changes of distal colon, expression of occludin protein and ultrastructure of intestinal epithelial cells. Furthermore, ratio of lactulose to mannitol (L/M) discharged in urine was evaluated.

Results

Comparing the results between TCM and model control groups, scores of DAI and histological lesions decreased significantly (P = 0.000 < 0.01), ultrastructures of intestinal epithelial cells and tight junctions were more complete. The expression of occludin protein (P = 0.001 < 0.01) increased while the L/M value decreased significantly (P = 0.000 < 0.01) in TCM group. There was no statistical difference between the TCM and mesalazine groups in results of each item (P > 0.05).

Conclusion

The decoction prepared with Yang-activating and stasis-eliminating TCM medicianls can restore intestinal mucosal epithelial cells and tight junctions the model rats with ulcerative colitis; it can reduce histological lesions and protect the permeability of intestinal mucosa barrier in the rats as well.  相似文献

OBJECTIVE

To investigate the potential chronic liver toxicity of oral administration of ethanol extract of Huangqin (Radix Scutellariae Baicalensis) (SBE) in Wistar rats.

METHODS

SBE was administered to rats by gavage for 26 weeks, at doses of 300, 1250, or 2500 mg?kg?1?d?1 respectively. The rats were euthanized at the end of 13 and 26 weeks daily oral dosing and following 4 weeks of recovery time. The changes of hematology, urinary, blood biochemistry and histomorphology were examined at each time point and focus on liver function and histological changes.

RESULTS

When SBE at a dose of up to 2500 mg?kg?1?d?1 was fed to male and female rats for 26 weeks, the liver tissue showed some inflammatory change that predominated by leukocyte infiltration but returned to normal after withdrawal. In addition, high-dose SBE treatment of 26 weeks in rats, glucose, electrolyte and lipid levels also have some changes. In addition, there are no other functional or organic lesions related to SBE treatment.

CONCLUSIONS

Long-term and high-dose SBE may cause liver damage, however, the structural damage of the liver can be restored after the ethanol extract stopping. SBE will be well-tolerated for long-term use as a drug or health food, but in order to ensure drug safety, liver function, and serum glucose, electrolyte and lipid levels should be monitored when using SBE long term.  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
