Differences in Protective Effect of Five Formulas for Promoting Blood Circulation and Removing Blood Stasis on Endothelial Cells of New Zealand Rabbits with Heart Blood Stasis Syndrome Through JNK Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo explore the differences in the protective effects of five formulas for promoting blood circulation and removing blood stasis on the aortic endothelial cells of New Zealand rabbits with heart blood stasis syndrome. MethodEighty New Zealand rabbits were randomly divided into a normal group （n=10） and an experimental group （n=70）. The heart blood stasis syndrome model was induced by starvation combined with a high-fat diet and adrenaline in the rabbits of the experimental group. Subsequently， the model rabbits were randomly divided into a model group， a Xuefu Zhuyutang group （3.55 g·kg-1·d-1）， a Taohong Siwutang group （2.66 g·kg-1·d-1）， a Danshenyin group （1.962 g·kg-1·d-1）， a Huoluo Xiaolingdan group （2.80 g·kg-1·d-1）， a Shixiaosan group （0.56 g·kg-1·d-1）， and a c-Jun N-terminal kinase （JNK） inhibitor （SP600125， 5 μg·kg-1）group. The normal group and the model group received the same amount of distilled water. The rabbits in five Chinese medicine groups were treated correspondingly by gavage， and those in the SP600125 group were injected with 0.5 mL of SP600125-dimethyl sulfoxide diluent. After the treatment， the aorta was collected， and terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL） assay was used to detect the apoptosis of aortic endothelial cells. The enzyme-linked immunosorbent assay （ELISA） was used to detect serum levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）. Western blot was used to detect the protein expression of JNK， phosphorylated JNK （p-JNK）， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cysteinyl aspartate-specific protease-9 （Caspase-9）， and cysteinyl aspartate-specific protease-3 （Caspase-3） in aortic tissues. Real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA levels of JNK， Bcl-2， Bax， Caspase-9， and Caspase-3 in aortic tissues. ResultFive formulas could improve the apoptosis of aortic endothelial cells to varying degrees. To be specific， Xuefu Zhuyutang and Taohong Siwutang were optimal in efficacy， followed by Huoluo Xiaolingdan， Shixiaosan， and Danshenyin， and SP600125 was the worst （P<0.05， P<0.01）. Five formulas could reduce the content of TNF-α and IL-6 （P<0.05， P<0.01）， down-regulate the protein expression levels of JNK， p-JNK， Bax， Caspase-9， and Caspase-3 （P<0.05， P<0.01）， decrease the mRNA expression levels of JNK， Bax， Caspase-9， and Caspase-3 （P<0.05， P<0.01）， and up-regulate the protein and mRNA expression levels of Bcl-2 （P<0.05， P<0.01）. ConclusionFive formulas can all reduce the apoptosis of aortic endothelial cells in New Zealand rabbits with heart blood stasis syndrome with different efficacies. It may be related to the different effects of five formulas on the JNK signaling pathway.

Objective:To observe the effects of Wenxin prescription on the key targets of gap 1/synthesis （G₁/S） cell cycle transformation in rats with atherosclerosis （AS）， and reveal the mechanism of Wenxin prescription in the treatment of AS. Method:Ninety SPF Wistar rats were randomly divided into a normal group （<italic>n</italic>=6） and a modeling group （<italic>n</italic>=84）. The rats in the modeling group were fed on a high-fat diet （4% cholesterol， 0.5% sodium cholate， 0.2% propyl thiouracil， 10% lard， 5% sugar， and 80.3% basal feed） for 60 days， and intraperitoneally injected with 400 000 U·kg^-1vitamin D₃， once a week for three weeks. The model rats were then randomly divided into a model group， high-dose （24 g·kg^-1）， medium-dose （12 g·kg^-1）， and low-dose （6 g·kg^-1） Wenxin prescription groups， and a rosuvastatin （1.8 mg·kg^-1） group. The groups with drug intervention were treated correspondingly by gavage for 30 days. The rats in the model group were administered with an equal volume of distilled water. The general condition of rats was observed after treatment. The levels of high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， and total cholesterol （CHO） were detected by enzyme-linked immunosorbent assay （ELISA）， and the atherosclerosis index （AI） was calculated. The pathological morphology of the coronary artery and aorta was observed by hematoxylin-eosin （HE） staining. The protein and mRNA expression of E2F transcription factor 1 （E2F1）， phosphorylated retinoblastoma protein （p-Rb）， cell division cycle 25 （Cdc25）， CyclinE， and CyclinD₁ was detected by Western blot and real-time fluorescence-based quantitative polymerase chain reaction （Real-time-PCR）， respectively. Result:Compared with the normal group， the model group showed intima thickening， smooth muscle proliferation， and plaque formation in the coronary artery and aorta， decreased HDL-C （<italic>P</italic><0.01）， increased LDL-C， CHO， and AI （<italic>P</italic><0.01）， elevated protein and mRNA expression of E2F1， Cdc25， p-Rb， CyclinE and CyclinD₁ （<italic>P</italic><0.05）. Compared with the model group， the rosuvastatin group and the Wenxin prescription groups showed slight intimal hyperplasia and lumen narrowing of the coronary artery and aorta， decreased levels of LDL-C， CHO， and AI （<italic>P</italic><0.01）， and declining protein and mRNA expression of E2F1， Cdc25， p-Rb， CyclinE， and CyclinD₁ to varying degrees （<italic>P</italic><0.05）. Conclusion:Wenxin prescription can significantly inhibit the expression of key proteins and genes of the G₁/S cell cycle， regulate G₁/S cell cycle transformation， and reduce vascular smooth muscle and intimal hyperplasia in AS rats.

Quantile regression model-based analysis of influencing factors on quality of life of inpatients with type 2 diabetes / 中华疾病控制杂志

Objective This study aimed to understand the status of health-related quality of life (HRQOL) among the hospitalized patients with type 2 diabetes (T2DM) in Yinchuan, so as to analyze the factors associated with HRQOL of hospitalized T2DM patients. The applied value of quantile regression in analysis of HRQOL was explored. Methods A cross-sectional study was conducted to obtain data of 480 hospitalized T2DM patients. The Chinese Normal Audit of Diabetes-Dependent Quality of Life (CN-ADDQoL) scale was used to assess the HRQOL status of patients. Traditional linear regression and quantile regression were used to analyze the influencing factors of HRQOL in hospitalized T2DM patients. Results The average weight impact (AWI) of hospitalized T2DM patients was-2.7(-3.6,-1.9), and the items with lowest score were in the dimension of “work life” (AWI,-4(-6,-2)), “eat” AWI,-4(-6,-2)) and “Anything of Drinking” (AWI,-4(-6,-2)). Linear regression results showed that 18-59 years old or the renal and circulatory complications were risk factors for HRQOL in T2DM hospitalized patients. Quantile regression further found that the better the quality of life, the weaker the effect on age (β1=0.931, P1=0.001; β2=0.699, P2=0.001; β3=0.370, P3=0.012; β4=0.313, P4=0.035), the rural residents (β5=-0.421, P5<0.001), insulin treatment (β3=-0.325; P3=0.024), the ocular (β1=-0.546, P1=0.008; β5=-0.352, P5=0.008), renal (β5=-0.358, P5=0.025) and circulatory complications (β1=-0.803, P1<0.001; β5=-0.302, P5=0.011) had effect on HRQOL at different quantiles. Conclusions Age, urban and rural residence, whether receive insulin therapy and complications are the influencing factors of HRQOL in hospitalized T2DM patients. The quantile regression model can show different factors affecting the quality of life of patients at different quintiles. The results from quantile regression can provide the targeted and reasonable recommendations for improvement of HRQOL of T2DM patients.

Effect of PARP-1 on cisplatin resistance in breast cancer MCF-7 cells / 中国病理生理杂志

AIM:To study the effect of poly(ADP-ribose)polymerase-1(PARP-1)on cisplatin resistance of human breast cancer MCF-7 cells and its possible mechanisms.METHODS: The expression of PARP-1 at mRNA and protein levels in MCF-7 cells and MCF-7/DDP cells was determined by real-time PCR and Western blot.The expression of PARP-1 in the MCF-7/DDP cells was blocked by PARP-1 siRNA.The cell viability and apoptosis were detected by the CCK-8 assay and flow cytometry analysis,respectively.Furthermore, the protein levels of PARP-1, Bcl-2, Bax, cleaved caspase-3,caspase-3,cytochrome C(Cyto-C),extracellular signal-regulated kinase(ERK)and phosphorylated ERK(p-ERK)were detected by Western blot.RESULTS:The expression of PARP-1 at both mRNA and protein levels was signifi-cantly up-regulated in the MCF-7/DDP cells.The expression of PARP-1 was increased in the MCF-7 cells treated with cis-platin.Knockdown of PARP-1 induced the apoptosis of MCF-7/DDP cells with an increased sensitivity to cisplatin.Mean-while,knockdown of PARP-1 down-regulated the protein levels of Bcl-2/Bax and p-ERK, but up-regulated the protein levels of cleaved caspase-3 and Cyto-C.After incubated with a specific ERK inhibitor U 0126,the cell viability in PARP-1 siRNA group was down-regulated significantly.CONCLUSION:Knockdown of PARP-1 increases the sensitivity of MCF-7/DDP cells to cisplatin,and promotes the cell apoptosis via mitochondrial apoptosis pathway.The mechanism may be re-lated to the attenuation of ERK signaling pathway by inhibiting phosphorylation of ERK.

Effect of different processed volatile oils from Angelica sinensis on urinary metabolomics rats / 中国中药杂志

Different processed volatile oils from AS on urine metabolites of normal rats were analyzed to reveal the possible metabolic pathways. Totally 50 male Waster rats were randomly divided into normal control group, C-ASVO group, J-ASVO group, T-ASVO group and Y-ASVO group, with 10 rats in each group. The normal group was given isovolumetric 0.5% polyoxyethylene sorbitan fatty acid ester（Tween-80）, while the other groups were given 0.176 mL•kg⁻¹ different processed volatile oils from AS. Drugs were given for 3 successive days. The urine was collected at 48 h with metabolic cages. GC-MS was employed to detect the metabolic fingerprint of rat urine in different times. Principal component analysis(PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) were adopted for a multivariate statistical analysis. Metabolites with potential differences were selected based on the results of variable importance in the projection(VIP) and t test. The metabolic pathway analysis(MetPA) database was built for different metabolites' metabolic pathways. The results showed that compared with the normal group, 31 kinds of endogenous metabolites in the different processed volatile oils from AS groups change significantly(P<0.05). And there were differences in normal rat urine metabolites among the different processed volatile oils from AS, of which the influence degree of J-ASVO was slightly stronger than C-ASVO, T-ASVO, and Y-ASVO. Therefore, the metabolism effect may be focused on energy metabolism, amino acid metabolism, fatty acid metabolism and glucose metabolism. This study focused on metabolism and mechanism of different processed volatile oils from AS, and provided new ideas for pharmacological actions of traditional Chinese medicines.

Comparative metabonomics study on urine in rat treated by Angelica sinensis volatile oil / 中国中药杂志

Metabonomics was employed to investigate the effect of Angelica sinensis volatile oil (ASVO) to the endogenous metabolites of normal rats, and to reveal the possible ways of metabolism in rats caused by ASVO. The fifty male Waster rats were randomly divided into five groups (each consists of 10 rats), such as control group, high dose group of ASVO, middle dose group of ASVO, low dose group of ASVO, and Aspirin group. They were given 0.9% saline, 0.352 mL x kg(-1) ASVO, 0.176 mL x kg(-1) ASVO, 0.088 mL x kg(-1) ASVO and ASP respectively with the equal volume of 0.2 mL. Drugs and vehicle were given for 3 successive days. The urine was collected at 12, 24, 36, 48 h after modeling with metabolic cages. Rat urine metabolic fingerprint in different stages was analyzed using GC-MS, based on which the principal component analysis (PCA)and orthogonal partial least-squares discriminant analysis (OPLS-DA) models were established for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. It was revealed that the middle dose of ASVO at 36 h induces a substantial change in rat urine. Compared with control group, seven kinds of endogenous metabolites in ASP group and ASVO group change significantly (P < 0.05), among which aconitic acid, succinic acid, citric acid, alpha-ketone glutaric acid, glycine and malic acid content had an upward trend (P < 0.05) and prostaglandin content had a downward trend (P < 0.01). The mechanism of ASVO and ASP have the similarity. It is likely that ASVO intervenes the metabolic process by affecting the energy, amino acid and lipid metabolism. Our work also indicates that rats administrated with ASVO can increase the energy metabolism of the body, induce the production of inflammatory substances and strengthen the body's immune ability. The result has also provide a proof for futher interpret ASVO pharmacological effects.
