The effects of grape seed oil on serum total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) levels were investigated in experimental hypercholesterolemic rats. The grape seed oil containing about 74% linoleic acid, multivitamins and trace elements. Each animal was given 4 ml/kg BW grape seed oil mixed in high fat ration for 40 days. The results in two experiments showed that TC concentration in the serum of rats fed grape seed oil was markedly lowered as compared to control, but serum HDL-C was less lowered. Furthermore, the ratio of HDL-C to TC in the experimental group was also significantly higher than that of control.

Objective To study the distribution of body constitutions of CHD patients with blood stasis syndrome;To explore the relationship between different body constitutions and their blood lipid levels.Methods WANG’s Constitutional Classification was used to diagnose body constitutions of 600 CHD patients with blood stasis syndrome, and analyze the relationship between the different body constitutions and triglyceride (TG) level, low density cholesterol (LDL-C) level, high density cholesterol (HDL-C) level.Results The four most common body constitutions of CHD patients with blood stasis syndrome in Taiyuan area were the constitutions of blood stasis, yang deficiency, qi deficiency and yin deficiency. The TG levels of the four body constitutions were higher than those of healthy people (P<0.01), but there was no obvious difference among TG levels of different body constitutions. The LDL-C level of the patients with the body constitution of blood stasis was higher than that of patients with other body constitutions and healthy people (P<0.01). Compared with healthy people, there was no obvious difference among HDL-C levels of different body constitutions (P>0.05).Conclusion There is a certain difference among the blood lipid levels in different body constitutions of CHD patients with blood stasis syndrome, and the patients of blood stasis syndrome with high LDL-C level are more dangerous than patients with other body costitutions.

This article was aimed to study the distribution and effects of apolipoprotein E (ApoE) gene polymorphism of different constitutional types among coronary heart disease (CHD) patients with blood stasis syndrome on vascular endothelial cell (VEC) function. The whole gene sequencing method was used to identify genotypes of ApoE gene among 556 CHD patients with blood stasis syndrome, in order to analyze the relationship between polymorphism of ApoE gene and the level of VEC function. The results showed that the frequency of E3/3 genotype of each physical group was significantly lower than that of the healthy group; and the frequency of E3/4 genotype was significantly higher than that of the healthy group. In addition, the frequency of E3/3 genotype in qi deficiency constitution group was higher than that of blood stasis constitution group and yang deficiency constitution group; but the frequency of E3/4 genotype in blood stasis constitution group and yang deficiency constitution group was higher than that of the qi deficiency constitution group. The levels of ET and ET/NO in each of genotype groups of blood stasis constitution, yang deficiency constitution, qi deficiency constitution of CHD patients with blood stasis syndrome were higher than that of the healthy group (P < 0.05). In the genotype group of blood stasis constitution of CHD patients with blood stasis syndrome, the frequency of E3/4+E4/4 genotype ET was higher than that of other genotypes (P < 0.01). The levels of ET, NO, ET/NO in genotype groups of yang deficiency constitution and qi deficiency constitution of CHD patients with blood stasis syndrome were not significantly different. It was concluded that ApoE genotype E3/4, E3/3 may be the susceptible genotypes of blood stasis syndrome in CHD. There is a certain difference among different constitutional types. CHD with blood stasis syndrome patients, who are the constitution of blood stasis, carrying the ApoE gene polymorphism of E4 allele may have the function of increasing the ET level.

Objective To explore the correlation of fatigue with health-promoting lifestyle in the udnergraduate students, so as to provide scientific evidence for the intervention. Methods A cross-section trial was carried out in the undergraduate students from a medical university in Guangzhou. By a self-designed questionnaire, the incidence of fatigue in the undergraduate students was figured out after data processing and statistical analysis. Results A total of 6 100 questionnaires were released, and 5 843 were responded, with a respondent rate being 95.79%. The number of effective questionnaires arrived 5 676. The results showed that the prevalence of fatigue among undergraduate students was 49.6%. The female had a higher risk than the male ( 51.6% vs 45.8%, P<0.01). The prevalence of fatigue in grade 1-3 students was 49.4%, 48.1% and 52.1% , respectively, the difference being insignificant among the three grades (P>0.05). The students with poor level of health-promoting lifestyle had a higher risk of suffering from fatigue (OR=6.647, 95%CI: 4.913-8.993). Conclusion Fatigue is prevalent among the undergraduate students. The incidence of fatigue can be reduced by increasing the level of self-actualization, physical exercise and pressure management.

Objective To compare the therapeutic efficacies of fire-needle acupuncture and Halometasone cream in treating sub-acute and chronic eczema. Method Totally 114 patients were divided into a treatment group and a control group. The treatment group was intervened by using fire-needle acupuncture, and the control group was by Halometasone cream. Itchy score and Eczema Area and Severity Index (EASI) were used for comparison before and after intervention. Result There were significant differences in comparing the markedly-effective rate and total effective rate between the fire-needle acupuncture group and the Halometasone control group according to the itchy score (P＜0.01). There were no significant differences in comparing the markedly-effective rate and total effective rate between the two groups according to EASI (P>0.05). Conclusion Fire-needle acupuncture is superior to Halometasone cream for acute and chronic eczema in relieving itch, action time and effect-sustaining duration.

Methods Six consecutive patients with metastases of the proximal femur, who could not be able to tolerate conventional surgery, underwent PIF together with POP. The results were analyzed. Results The procedure was successfully accomplished in all six patients. Neither pulmonary embolism nor death occurred in all patients during and after the operation. No fracture at operated area was observed during follow-up period. Conclusion For stabilization of proximal femoral metastatic lesion with impending pathological fracture, percutaneous internal fixation combined with pecutaneous osteoplasty is a safe and effective technique.

This study was aimed to investigate the effect of Bu-Shen Y i-Sui Sheng-Xue (BSYSSX) method on pro-liferation and differentiation mechanisms of hematopoietic progenitor cells. The rat models were established by 60Co-γrays and cyclophosphamide. Compound Chinese medicine was gavaged to rats of the normal control group, model group, stanozolol group, Yi-Sui Sheng-Xue (YSSX) group, Wen-Shen Sheng-Xue(WSSX) group and Zi-Shen Sheng-Xue (ZSSX) group. Then, serum of rat was prepared. Rat bone marrow cells were incubated with AA rats serum ac-counted for 20% and the number of hematopoietic progenitor cells colony-forming units (CFU) were counted. The level of GATA-1 and PU.1 mRNA in colony cells were detected with RT-PCR. The results showed that compared with the normal control group, the number of bone marrow cells, CFU-E, BFU-E, CFU-GM, as well as the expres-sion of GATA-1 and PU.1 mRNA in the model group decreased significantly (P< 0.01). Compared with the model group, the number of bone marrow cells, CFU-E, BFU-E, CFU-GM of each treatment group were significantly in-creased (P< 0.01). CFU-E and BFU-E of the ZSSX group were better than the YSSX group (P < 0.01). CFU-GM of the ZSSX group was better than the YSSX group and the WSSX group. The expression of GATA-1 and PU.1 mR-NA in each treatment group were significantly higher than the model group (P< 0.01). The expression of GATA-1 mRNA in the ZSSX group was better than the YSSZ group and WSSX group (P< 0.05). The expression of PU.1 mR-NA in the ZSSX group was higher than the YSSX group and WSSX group. It was concluded that BSYSSX method may increase the expression of GATA-1 and PU.1 mRNA in order to promote the proliferation and differentiation of bone marrow hematopoietic progenitor cells. The ZSSX method was better than the YSSX method and WSSX method.

Objective To investigate the protective effects of the 14-3-3 protein overexpression on the injury of PC12 cell induced by MPP~+ and its mechanisms.Methods For expression in mammalial cells, pcDNA3.1(+)-14-3-3 plasmid was constructed and transfeeted into PC12 cell with Lipofectamine~(TM)2000. The overexpression of transfected 14-3-3 gene in PC12 cell was determined by immunofluorescence and Western blotting.The effects of 14-3-3 overexpressing on the cells viability,apoptotie ratio and the activity of superoxide dismutase(SOD)as well as glutathione peroxidase(GSH-Px)of PC 12 cell treated with MPP~+ were measured by MTT assay,flow cytometry analysis and microplate reader respectively.Results The expression of 14-3-3 protein in transfection group(1.19?0.06)increased evidently compared with control group(0.75?0.05).And the antioxidant enzyme activity assession,MTT assay and flow cytometry analysis shows that the overexpression of 14-3-3 protein elevates the activity of SOD(transfection group:(9.13? 0.41)U/mg protein,MPP~+ group:(6.45?0.52)U/mg protein)and GSH-Px(transfection group: (89.66?3.42)?mol/mg,protein MPP~+ group:(82.73?4.15)?mol/mg protein),increases the cell viability(transfection group:0.78?0.06,MPP~+ group:0.54?0.07),and inhibits cell apoptosis (transfeetion group:11.87%?3.26%,MPP~+ group:36.30%?2.39%)of PC12 induced by MPP~. Conclusion The overexpression of 14-3-3 protein could elevate the activity of antioxidant enzymes SOD and GSH-Px,reduce oxidant stress,alleviate MPP~+ toxicity,and thus inhibit the apoptosis of PC12 cell induced by MPP~+.

In this study,a panel of monoclonal antibodies (mAbs) against Porcine reproductive and respiratory syndrome virus(PRRSV),named as 8C9 and4B4,were produced by fusing SP2/0 myeloma cells and spleen cells of BALB/c mice immunized with the PRRSV (TCID50=5.5),screened by the indirect ELISA and subjected to several limiting dilutions.mAbs were then identified by biological characterization.Among the two fusion cell strains,8C9 belonged to the IgG1 subclass and 4B4 belonged to the IgG2a subclass.The titers in cell culture supernatant and abdomen liquor reached to 1:104and 1:105,respectively.The specificity test indicated that the two cells had specific reactions for the PRRSV and GP5 protein respectively,and no reaction with Classical swine fever virus (CSFV) or Swine vesicular disease virus (SVDV).The molecular weights of the heavy chain and light chain were about 45.0 kDa and 25.0 kDa,respectively.In neutralization activity tests,the results showed that the prepared mAb 4B4 can protect 50% of cells with no CPE in dilution up to 1:512,but mAB 8C9 has no neutralization activities to PRRSV.
