OBJECTIVE
To examine the effects of Cuzhi liquid on learning and memory abilities in a mouse model of Alzheimer's disease (AD).METHODS
One hundred mice were divided into the normal, AD model, piracetam group, Cuzhi liquid low dose and Cuzhi liquid high dose, each group 20 mice. The AD mouse model was induced by daily intraperitoneal injection of D-galactose and sodium nitrite. AD mice then received intragastric administration of piracetam or Cuzhi liquid for 60 d, and changes in learning and memory abilities were assessed using the water maze test. The activity of acetylcholinsterase (AchE) and monamine oxidase (MAO), and the levels of nitrogen monoxidum (NO) and malonaldehyde (MDA), were measured in brain tissues. Amyloid protein deposition was assessed by methyl violet staining, and B-cell lymphoma-2 (Bcl-2) expression in the hippocampal cornus ammonis 1 region was detected by immunohistochemistry.RESULTS
In the water maze test, the escape latency of the model group was longer than that of the normal group (P < 0.01). The escape latency of the three using drug treatment groups was significantly less than that of the normal group (P < 0.05). The activity of AchE and MAO, and the levels of NO and MDA, in the brain of the model group were significantly higher than that of the normal group (P < 0.01), but significantly reduced in the three drug treatment groups compared with the model group (P < 0.05). AchE activity showed a greater reduction in the two Cuzhi liquid groups compared with the piracetam group (P < 0.01), to levels similar to the normal group. There were no differences in MAO activity or NO levels between the three drug treatment groups, while MDA levels were reduced more in the high-dose Cuzhi liquid group compared with the other treatment groups (P < 0.01). Hippocampal Bcl-2 expression was significantly reduced in the model group compared with the normal group (P < 0.01), but significantly improved in the three drug treatment groups (P < 0.05). The high-dose Cuzhi liquid group showed a significantly greater recovery in Bcl-2 expression compared with the other treatment groups.CONCLUSION
Cuzhi liquid can improve learning and memory impairment in an AD mouse model. The mechanism of action may relate to reduced AchE and MAO activity, and reduced NO and MDA levels, in the brain, and improved Bcl-2 expression, an inhibitor of apoptosis. 相似文献3.
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4.
Objective
To investigate the regulatory mechanism of the c-Jun N-terminal protein kinase (JNK) signaling pathway in substantia nigra (SN) dopaminergic neurons inflammation and apoptosis, and the neuroprotective effect of Zishenpingchan granules in mice with Parkinson's disease (PD) induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).Methods
PD model mice were established by intraperitoneally injecting MPTP. Sixty mice were divided into a model group, Traditional Chinese Medicine (TCM) group and control group. The mice of the TCM group were administered Zishenpingchan granules 7 days before PD induction. Seven days after PD induction, we examined locomotor activity, and performed the rotarod test and swimming test, to evaluate limb movement function. Furthermore, we used immunohistochemistry and western blotting to examine the expression of tyrosine hydroxylase (TH), cyclooxygenase-2 (Cox-2), caspase-3 and p-JNK. The terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) method was used to examine neuron apoptosis in the SN.Results
Compared with the control group, the mean score of locomotor activity, rotarod test and swimming test was significantly lower in the model group (P < 0.05); the TH-positive neuron expression was significantly decreased in the SN pars compacta (SNpc); the protein expression levels of Cox-2, caspase-3 and p-JNK was obviously increased; and the number of TUNEL-positive neurons in the SN was increased (P < 0.01). Compared with the model group, the mean score of neurobehavioral tests in the TCM group was obviously higher, the loss of TH-positive neuron significantly decreased, the protein expression levels of Cox-2, caspase-3 and p-JNK obviously decreased, and the number of TUNEL-positive neurons in the SN clearly decreased (P < 0.01).Conclusion
The JNK pathway plays an important role in the regulation of inflammation and apoptosis in nigral cells in PD mice. TCM can suppress the over-activation of the JNK pathway in the SN, and alleviate the inflammatory response in nigral cells and dopaminergic neuron apoptosis in PD mice. 相似文献5.
OBJECTIVE
To investigate the effect of optimal combination (E) of Huangqi (Radix Astragali Mongolici) and Ezhu (Rhizoma Curcumae Phaeocaulis) on proliferation and apoptosis of A549 lung cancer cells and the possible mechanism underpinning the action.METHODS
A uniform design method was used to optimize the E of Huangqi (Radix Astragali Mongolici) and Ezhu (Rhizoma Curcumae Phaeocaulis) in A549 lung cancer cells. MTS assay was applied to analyze the effect of the component formula of Huangqi (Radix Astragali Mongolici) and Ezhu (Rhizoma Curcumae Phaeocaulis) on A549 cells viability in various uniform design groups. A549 cells with exponential growth in routine culture were exposed to CoCl2 (200 μmol/L) to mimic hypoxic conditions. Group 0 was treated with RPMI-1640, the group CoCl2 was treated with CoCl2 (200 μmol/L), the group DDP + CoCl2 was treated with 4 mg/L Cisplatin injection (DDP) + CoCl2 (200 μmol/L), and the drug group was treated with various dose of E (0.5E, 1E, 2E) + CoCl2 (200 μmol/L). All groups were cultured for 24 h. Cell apoptosis was measured by Annexin V-FITC/propidium iodide double staining and flow cytometry. Western blot assay and quantitative real-time polymerase chain reaction (qRT-PCR) were employed to detect the protein and mRNA expression of B-celllymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax) and cysteinyl aspartate specific proteinase-3 (caspase-3).RESULTS
The E obtained by the uniform design was comprise of 200 mg/L Astragalus polysaccharide (X1) and 32 mg/L Curcumin (X3). Group DDP+ CoCl2, group 1E + CoCl2 and group 2E + CoCl2 promoted the apoptosis of A549 cells (P < 0.05). Group 1E + CoCl2 and group 2E + CoCl2 had no statistically significant differences compared with the group DDP + CoCl2 (P > 0.05). Compared with group 0, various doses of E + CoCl2 could up-regulate the expression of Bax and caspase-3 and down-regulate the expression of Bcl-2 at protein and mRNA levels (P < 0.05).CONCLUSION
Astragalus polysaccharide and Curcumin was the optimal combination of Huangqi (Radix Astragali Mongolici) and Ezhu (Rhizoma Curcumae Phaeocaulis). E promoted the apoptosis of A549 cells. Combination of Astragalus polysaccharide and Curcumin increased the expression of Bax and caspase-3, and decreased the expression of Bcl-2 to initiate apoptosis in A549 cells under chemical-induced hypoxia. 相似文献6.

OBJECTIVE
To investigate the effective ingredients of Danshen (Radix Salviae Miltiorrhizae) and Honghua (Flos Carthami) (Danhong) on protective properties towards neonatal rat hippocampal neurons under hypoxia condition.METHODS
Primary culture of neonatal rat hippocampal neurons was used to model hypoxia damage on the hippocampus. Methyl thiazolyl tetrazolium (MTT) assay and preliminary experiments were conducted to identify the four effective ingredients of Danhong, along with the injection of positive drug onto hippocampal neurons at a non-toxic dosage level. The cultured cells were randomly divided into 12 groups: the normal group, model group, positive drug control group and nine compatibility groups of the four effective ingredients. Different test methods were applied to determine lactate dehydrogenasein (LDH), total superoxide dismutase (T-SOD), malondialdehyde (MDA), 6-keto prostaglandin Fla (6-keto-PGF1a), thromboxane B2 (TXB2), mitochondrial membrane potential (MMP), free calcium ions concentration ([Ca2+]i) and early onset cell apoptosis.RESULTS
Different compatibility groups could inhibit the content of LDH and intracellular calcium overload, increase activity in T-SOD, decrease level of MDA and TXB2, improve level of 6-keto-PGF1a and MMP, and prevent the early onset cell apoptosis.CONCLUSION
The compatibility of four effective ingredients of Danhong had protective effect toward hippocampi hypoxia. The mechanism might be related to inhibit oxidative stress damage and cell apoptosis, resist thrombosis, and reduce the intracellular calcium ion of overload. 相似文献7.

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9.

OBJECTIVE
To evaluate the anti-tumor activity of ethyl acetate fraction (EFA), extracted with ethanol from the root of “Dai-Bai-Jie” in A549 cancer cells and its underlying mechanism.METHODS
“Dai-Bai-Jie” was extracted with 95% ethanol-aqueous (DBJ-1), 50% ethanol-aqueous (DBJ-2), and water (DBJ-3) by reflux method. 95% ethanol-aqueous extract was separated byethyl acetate (EFA) and n-butyl alcohol (DBJ-5), consecutively. The SRB method was used to evaluate the cytotoxic activity. Annexin V-FITC staining was applied to observe the apoptosis and analyze the cell cycle activated by EFA in A549 tumor cell. Western blot was used to detect the apoptosis/related proteins expressions. A549 tumor cellsbearing nude mice model was employed to measure the tumor volume, mice weight, and tumor inhibition ratio in order to verify the antitumor activity in vivo.RESULTS
DBJ-1 and EFA showed better cytotoxic activity on A549 tumor cells with IC50 25 and 3.5 µg/mL, respectively. EFA can exhibit the proliferation, arrest cell cycle at G0/G1 phase, and induce apoptosis in A549 tumor cells in vitro. The mechanisms of apoptosis induced by EFA may be associated with decreasing Bcl-2 protein expression and increasing p53, Bax, Caspase-3, and Caspase-8 proteins expression. EFA also possessed significant anti-tumor efficacy in nude mice, and little toxicity was observed in the host.CONCLUSION
EAF could induce A549 tumor cells apoptosis and G0/G1 cell cycle arrest. A549 tumor cells apoptosis induced by EAF may be associated with the decrease in the ratio of Bcl-2 and Bax mRNA levels, and increase in the expression of p53, Caspase-3, and Caspase-8 proteins. 相似文献10.

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11.

OBJECTIVE
To investigate the efficacy of Ciji Hua' ai Baosheng formula (CHBF) on microvessel density (MVD) and vascular endothelial growth factor (VEGF), kinase insert domain-containing receptor (KDR) and basic fibroblast growth factor (bFGF) expression in serum and tumor tissue of mice receiving chemotherapy for the treatment of H22 hepatocellular carcinoma.METHODS
Sixty Kunming mice were injected subcutaneously with H22 hepatoma carcinoma cell suspensions into the right anterior armpit. Seven days later, all transplanted tumor were formed and the mice were intraperitoneally injected 200 mg/kg cytoxan (CTX) to establish the models of tumor-bearing mouse chemotherapy, then they were randomly divided into model group, continuing CTX chemotherapy group (CTX group), and three CHBF (117, 58.5 and 29.25 g/kg) groups. After ten days of treatments, histology was observed, contents of VEGF, KDR and bFGF in serum and tumor tissue were measured by enzyme-linked immunosorbent assay (ELISA), VEGF and bFGF protein expression and MVD tagged by CD34 were detected by immunohistochemisty.RESULTS
MVD in CHBF (117, 58.5 g/kg) and CTX groups was significantly lower than that in model group (P < 0.01); expressions of VEGF, KDR and bFGF in serum and tumor tissue in CHBF (117 g/kg) group were less than those in model group (P < 0.05; P < 0.01); the expressions of MVD, VEGF and bFGF in tumor tissue of CHBF (117 g/kg) group were also less than those in CTX group (P < 0.05; P < 0.01).CONCLUSION
CHBF can effectively reduce the expression of VEGF, KDR and bFGF in serum and tumor tissue, and decrease MVD and delay tumor progression. 相似文献12.

OBJECTIVE
To assess the efficacy and safety in 105 patients with seasonal Influenza in Beijing, the mixture prepared with Chinese medicines follows the treatment regimen of releasing exterior cold and clearing interior heat.METHODS
Total 330 patients with seasonal influenza were enrolled and randomly and averagely divided into the Chinese herbal medicine, the western medicine and the Chinese patent medicine group. They were treated with Chinese medicine Oseltamivir Phosphate Capsules and the Scattering Wind and Resolving Toxins Capsules. The main efficacy indicators were the antifebrile onset time and recovery time of body temperature. The efficacy and safety of the mixture was scientifically evaluated. Comparisons of several variables were analyzed.RESULTS
Median antifebrile onset time of the Chinese herbal medicine group was significantly shorter than the western medicine group (P < 0.05) and the Chinese patent medicine group (P < 0.05). The median antifebrile recovery time of the Chinese herbal medicine group was significantly shorter than the Chinese patent medicine group (P < 0.05). The groups evaluated by TCM symptom pattern effect, both the Chinese herbal medicine group and Western Medicine group were better than the Chinese patent medicine group (P < 0.05). The disappearance rate of main symptoms and some minor symptom patterns of the Chinese herbal medicine group were higher than the other 2 groups.CONCLUSION
The mixture of releasing exterior cold and clearing interior heat could significantly shorten the fever time with safety. 相似文献14.

OBJECTIVE
To investigate the effects of electroacupuncture (EA) at the Guanyuan (CV 4) or Sanyinjiao (SP 6) acupoints on the hypothalamus-pituitary-ovary (HPO) axis and spatial learning and memory in female mice.METHODS
Nine-month-old female mice with senescence-accelerated mouse prone 8 (SAMP8) were divided into three groups: the disease model, EA-Guanyuan and EA-Sanyinjiao groups. Concurrently, 9-month old female mice with senescence-accelerated mouse resistance 1 (SAMR1) were set as the control model group. The two treatment groups were given the same pattern of EA stimulation. Gonadotropin-releasing hormone, luteinizing hormone, follicle-stimulating hormone (FSH) and Serum estradiol levels in the Hypothalamus-pituitary-ovary axis were assessed by enzyme-linked immunosorbent assay to determine the HPO axis function level. Spatial learning and memory were assessed by the Morris Water Maze (MWM) test.RESULTS
(a) HPO axis: compared with the control model group, the disease model group displayed a decrease in E2 levels (P < 0.01), and an increase in GnRH, LH and FSH levels (P < 0.01). E2 levels were increased in EA treatment groups compared with the disease model group (P < 0.05). In contrast, GnRH and LH and FSH levels were reduced (P < 0.05). EA-Sanyinjiao group was superior than EA-Guanyuan group on increasing E2 and declining GnRH levels (P < 0.01). (b) The MWM test demonstrated that the response latency in the EA-Sanyinjiao treatment group declined from day 2 to day 5 compared with the disease model group (P < 0.05), whereas the EA-Guanyuan treatment group showed no significant difference.CONCLUSION
EA can regulate hormone (E2, FSH, LH, GnRH) levels in the HPO axis and the spatial learning and memory ability in female SAMP8 mice. Moreover, this effect may have been more pronounced in the EA-Sanyinjiao group than the EA-Guanyuan group. The underlying mechanism of the EA-induced changes may be related to gonadal hormone shifts in the HPO axis, followed by an improvement in spatial learning and memory. 相似文献15.
Objective
To investigate the effect of Flavone from Zhongjiefeng (Herba Sarcandrae Glabrae) on the platelet number in immune-induced bone marrow failure (BMF) and its mechanism of mitochondrial apoptotic pathway.Methods
Immune-induced BMF model, established in mice, was randomly divided into four groups: normal control group without BMF, BMF control group, cyclosporine (CSA) group and flavone group (n = 10 in each group). Mice were given 0.027 g/kg cyclosporine or 0.2 g/kg flavone lavage daily in either the cyclosporine or flavone group respectively. Platelet count, mitochondrial transmembrane potential (ΔΨ), cytochrome C (Cyt C), phosphatidylserine (PS), changes of calcium ion (Ca2+), and protein expression of mitochondrial apoptotic pathway including B-cell lymphoma-2 (bcl-2) Homologous Antagonist-Killer Protein (Bak), bcl-2-associated X protein (Bax), caspase-3, caspase-8, and caspase-9 were examined and compared.Results
Compared with the normal control group, the BMF group had significantly lower levels of platelet count, ΔΨ, and expressions of caspase family proteins as well as higher levels of Cyt C, PS, Ca2+, and expressions of Bak and Bax (all P < 0.05). Compared with the BMF group, the CSA and flavone groups had significantly higher ΔΨ and expressions of caspase family proteins (all P < 0.05) whereas the levels of Cyt C, PS, Ca2+, and expressions of Bak and Bax were reduced (all P < 0.05). More importantly, the flavone group had higher levels of Cyt C, Ca2+ and expressions of Bak and Bax compared with the CSA group (all P < 0.05), while the levels of PS and caspase family proteins were reduced (all P < 0.05).Conclusion
Flavone from Zhongjiefeng (Herba Sarcandrae Glabrae) significantly increases the platelet number and prevents its apoptosis through mitochondrial pathway. 相似文献16.

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17.
OBJECTIVE
To evaluate the therapeutic effects of nape acupuncture combined with rehabilitative swallowing training for dysphagia caused by pseudobulbar palsy, and to compare it with rehabilitative swallowing training alone, and to observe the improvement in quality of life after the therapy.METHODS
One hundred patients were randomly divided into two groups: the rehabilitative swallowing training group (control group, n = 50) and the nape acupuncture combined with rehabilitative swallowing training group (experimental group, n = 50). Each group had 8 weeks’ therapy, 5 times a week. Patients in the control group received rehabilitative swallowing training, while those in the experimental group received nape acupuncture therapy based on swallowing rehabilitation. The outcomes were assessed by the repetitive saliva-swallowing test (RSST), water swallow test (WST), standardized swallowing assessment (SSA), and a swallow quality-of-life questionnaire (SWAL-QOL). Correlations of onset age, onset frequency and lesion location with the efficacy of the acupuncture treatment were also observed.RESULTS
The scores for RSST, WST, and SSA in both groups were lower than before the therapy (P < 0.001), although the changes were more marked in the experimental group than in the control group (RSST and WST, P< 0.005; SSA, P< 0.001). Both groups recorded changes in SWAL-QOL index after the therapy (P< 0.001); and the experimental group scored higher than the control group (P < 0.001). The efficacy of acupuncture was not correlated with location (P > 0.05), but was related to onset age (P < 0.05) and onset frequency (P < 0.01).CONCLUSION
Nape acupuncture combined with rehabilitative swallowing training has an effect on dysphagia caused by pseudobulbar palsy and improves quality of life. 相似文献18.

OBJECTIVE
To evaluate the efficacy of moxibustion, through stimulating acupoints of Danzhong (CV 17) and Ganshu (BL 18) in rats with hyperplasia of mammary gland (HMG) which induced by estrogen and progestogen.METHODS
Thirty female Sprague-Dawley rats were randomly divided into saline control group, HMG model group, and HMG moxibustion group with 10 in each group. Saline control was the group injected by saline. HMG model were created by injection of estrogen and progestogen. Moxibustion group was also injected of estrogen and progestogen with moxibustion at the same time. The Changes of nipple diameter and height were measured. The rats’ skin temperature was recorded by an infrared thermal camera at the nipples, mammary areas, Danzhong (CV 17) and Ganshu (BL 18). Pathological changes of mammary gland in rats were also observed under light microscope.RESULTS
The diameter and height of the nipples in model group were prominently bigger and higher than that in control group (P < 0.01). The diameter and height in moxibustion group were prominently smaller and lower than that in model group (P < 0.01), and there was no significant difference between moxibustion group and control group. Compared with control group, skin temperature of the nipples, mammary area, and acupoints Danzhong (CV 17) and Ganshu (BL 18) decreased prominently in model group (P < 0.01-0.05). Compared with model group, skin temperature of that in moxibustion group increased prominently (P < 0.05).CONCLUSION
Treatment with moxibustion can effectively decrease the HMG rats’ nipple diameter and height, and increase the skin temperature in HMG model rats at the nipples, mammary areas, Danzhong (CV 17) and Ganshu (BL 18). This study convinces the therapeutic effect of moxibustion on mammary gland hyperplasia. 相似文献19.
OBJECTIVE
To explore the blood flow differences in cun-kou (radial) artery and anterior tibial artery between normal people and patients with chronic gastritisMETHODS
Using doppler ultrasonography, blood flow charts [peak systolic velocity (VP), maximum blood flow velocity in diastole (VD), mean blood flow velocity (VM), pulse index (PI), resistance index (RI), blood vessel diameter (D), vessel volume (SV), circulation blood flow periodic time (ET)] measured by at cun-kou (radial) artery and anterior tibial artery in normal group (n = 30) and chronic gastritis group (n = 30) in department of ultrasound, Beijing Anzhen hospital, capital medical university.RESULTS
In the doppler flow charts of the normal group, there were statistically significant differences in VD, VM, D, RI, SV, ET between cun-kou artery and anterior tibial artery (P < 0.05), and there were more statistically significant differences in PI between cun-kou artery and anterior tibial artery (P < 0.01). In the comparison of doppler flow charts in the chronic gastritis group, there were statistically significant differences in VD, VM, D, RI, SV, ET between cun-kou artery and anterior tibial artery (P < 0.05), and there were more statistically significant differences in PI between cun-kou artery and anterior tibial artery (P < 0.01). In the comparison of doppler flow charts between normal group and chronic gastritis group, there were statistically significant differences in SV, ET between normal group and chronic gastritis group (P < 0.05), and there were more statistically significant differences in PI between normal group and chronic gastritis group (P <0.01).CONCLUSION
Based on the differences in doppler flow charts between the normal group and the chronic gastritis group, the doppler flow charts of cun-kou artery and anterior tibial artery were not only proved to be significantly different, but also provided quantitative objective indexes for the study of cun-kou artery and anterior tibial artery doppler flow charts of normal people and chronic gastritis patients. This study also proves that the doppler flow chart of the anterior tibial pulse is of great significance for the diagnosis of chronic gastritis. 相似文献20.
