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 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.

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.

Objective To summarize the experience in operation manner and surgical technique of refractory cholelithiasis.Methods A total of five hundred and twenty one patients with refractory cholelithiasis admitted to Hunan Provincial People's Hospital from Jan.1990 to Dec.2007 were involved in this study for retrospective analysis.Results All patients in this group accepted surgery.Apart from three cases of perioperative death with liver and kidney failure,the remaining five hundred and eighteen cases had no serious complications,were cured and discharged.The imaging examination showed residual stone in seventy cases,accounting for fifteen percent.Four hundred and twenty one patients were followed up.The mean time of follow-up was seven years and six months (range 5 months - 17 years).Good result rate was 90.1%(381/423).Conclusions Most intractable cholelithiasis can be cured radically.Individual surgery programme,fine and standard surgical procedure are the key to treatment effect.

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.

Objective To investigate the expression of hypoxia inducible factor-1α(HIF-1α)in the transplanted liver in rats and the role of HIF-1α in the JNK signaling pathway.Methods Ninety-six SD rats were randomly divided into normal control(NC)group,autotransplantation(AT)group,hypoxia preconditioning (HP)+ AT group according to simple random sampling method.No treatment was applied to the rats in the NC group except for blood vessel separation.Stable rat models of 70％ AT was established in the AT group.Rats in the HP + AT group were given 8％ oxygen mixed gas for 90 minutes before the operation.The levels of alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were detected at 1,2,12,24 hours after operation,and the expression of HIF-1α in the hepatic tissue,mRNA expression of c-Jun,and protein expression of Cleaved Caspase-3 were detected by immunohistochemical staining,reverse transcription-polymerase chain reaction and Western blot,respectively.All data were analyzed using the analysis of variance or t test.Results The levels of ALT and AST in the HP + AT group were significantly lower than those in the AT group,while higher than those in the NC group at 1,2,12 and 24 hours after the operation(F=2631.371,1177.642,810.383,682.848;743.618,1095.522,375.995,580.613,P ＜0.05).The protein expression levels of HIF-1α in the AT group were significantly lower than those in the HP + AT group,but higher than those in the NC group at 1,2,12 and 24 hours after operation(F = 191.737,284.482,459.419,213.782,P ＜ 0.05).The mRNA expression levels of c-Jun in the HP + AT group were significantly lower than those in the AT group,while higher than those in the NC group at 1,2 and 12 hours after operation(F = 66.211,53.169,9.645,P ＜ 0.05).There was no significant difference in the mRNA expression of c-Jun among the 3 groups at 24 hours after operation(F = 1.100,P ＞ 0.05).The protein expressions of Cleaved Caspase-3 in the HP + AT group were significantly lower than those in the AT group,while higher than those in the NC group at 1,2,12 and 24 hours after the operation(F =23.133,31.158,14.347,29.043,P ＜ 0.05).Conclusion High expression of HIF-1α after HP inhibits apoptosis of hepatic cells and alleviates ischemia reperfusion injury of hepatic tissues by suppressing JNK activation,down-regulating protein expression of Cleaved Caspase-3 after orthotopic liver transplantation in rats.
