The pulse wave velocity(PWV)known as one of important monitoring methods in crowd more can precisely reveal the occurrence of cardiovascular events.The brachia-ankle PWV(baPWV)is referred to cosmically epidemiological study in crowd.PWV is known as a vicarious mark of arteriosclerotic burden and an independent risk factor.Moreover,used for decision the therapeutic effect.Our study initially showed that PWV was only a mark of cardiovascular events and was not a predict end point.

Objective To investigate the trend of blood lipid in female elderly with aging, and further discuss the strate?gies of blood lipid regulation therapy and prevent and control cardiovascular disease during senile period. Methods Physi?cal examination data of 847 elderly female cadres (in 1 837 females) were analyzed to investigate the general level and abnor?mality features of blood lipid in this elderly female group. Results The levels of total cholesterol (TC), triacylglycerol (TG), low density lipoprotein-cholesterol (LDL-C) and body mass index (BMI) were significantly higher in elderly group than those of non-elderly group (P<0.01). The levels of TC, TG, LDL-C, LDL-C/HDL-C, TG/HDL-C, and non-HDL-C increased with aging, and then decreased at the same age group, and reached the peak value at 60 to 69 years old. The level of HDL-C showed a reverse pattern, decreased with aging first and then increased at the same group, and reached the bottom at 60 to 69 years old. Conclusion In this elderly female cadre population, the level of blood lipid changes regularly with aging, indicat?ing the high risk of cardiovascular disease.

OBJECTIVE:
To analyse the risk factors involved in local failure following radiotherapy and chemotherapy to nasopharyngeal carcinoma.
METHOD:
A retrospective analysis was carried out to review the histopathological data from 308 NPC patients who recieved medical treatment between 2004 and 2006. The incidence and the risk factor for local treatment failure were evaluated in a model that included the following factors: sex, age, T and N staging, histological grade of primary tumor, presence of cervical lymph node metastasis, size and laterals of positive neck nodes, levels involved, ways of radiation and condition of concurrent chemotherapy. Univariate chi2 test and multivariate stepwise logistic regression model were used for the analysis. Statistical analysis of survival of patients with local residues and recurrence was performed using Kaplan-Meier method.
RESULT:
Ninty-three cases (30.2%) presented local residues and recurrence in 308 patients of nasopharyngeal carcinomas. In the univariate analysis, it was confirmed that the following variables correlated to local failure, i. e., T staging (P < 0.01), N staging (P < 0.01), presence of cervical lymph node metastasis (P < 0.05), size and laterals of positive neck nodes (P < 0.05, respectively). In the multivariate analysis, the most ignificant risk factors for local failure were the T staging only. Kaplan-Meier analysis showed that overall survival rates of 71 NPC patients with local residues and recurrence who received re-treatment were 77.2% at 1 year, 40.4% at 3 years, 22.4% at 5 years, respectively.
CONCLUSION
T staging is the key risk factors in determining the development of local failure following radiotherapy or chemotherapy in NPC patients. Patients with primary tumor infiltrating bone have the higher risk of developing local residues and recurrence. Retreatment to the patients suffering from local failure can imrove survival rates.

Protein ubiquitin-like modification of Neddylation is an important post-translational modification mode of protein to widely regulate cell cycle, growth, development and other biological processes. Recent studies have found that MLN4924, small molecule inhibitor of Neddylation modification, has a significant anti-tumor effect, which can inhibit the tumor growth by inducing cell cycle arrest, senescence and apoptosis, and inhibiting tumor angiogenesis. This paper reviews the related mechanism research of cell programmed death induced by Neddylation modification pathway inhibitor MLN4924.

[Objective] To observe the in-vitro inductive effect of ginsenosides (GS) on differentiation of rat bone marrow mesenchymal stem cells (MSC) into myocardial cells. [Methods] Marrow stromal cells were isolated from adult SD rats, and then were cultured and cloned by density gradient method and adhesive cultivation to prepare the primary MSC. The cell surface antigens of CD34 and CD44 were detected with flow cytometer to identify MSC. After subculture, the 8th generation of continuous MSC were induced by GS (250 mg/L) and 5-aza (5-azacytidine, 10 ?mol/L) and GS + 5-aza (250mg/L and 10 ?mol/L respectively) for 24, 48 and 72 hours to differentiate to myogenic cells. Meanwhile, a blank control group was set to compare the effect. After the induction, myocardial cell percentage was worked out after examining MSC count and positive cells count under the phase contrast microscope. The specific proteins of Desmin and cardiac troponin I (cTnI) in myocardial cells were detected by immunohistochemistry method, and the cardiac-specific gene expression of ?-MHC (myosin heavy chain) and ?-MHC in myocardiocytes was examined by reverse transcription-polymerase chain reaction (RT-PCR) analysis. [Results] The cultured marrow stromal cells grew well, spindle in shape, and their CD44 expression was positive, indicating that marrow stromal cells differentiated to MSC. After induction with GS and 5-aza, MSC differentiated to myocardial cells, and the myocardial cell percentage was 38% in GS group, 35% in 5-aza group and 39% in GS + 5-aza group, the difference being insignificant. The expression of Desmin, cTnI and MHC in MSC was positive, and MSC were spindle-shaped and looked like fibroblast, indicating that MSC differentiated to myocardial cells. [Conclusion] Ginsenosides can induce MSC to differentiate to myogenic cells in-vitro, and this will supply evidence for cell transplantation.

Objective To isolate and identify the chemical constituents of 95% alcohol extract in the fruits of Ailanthus altissima. Methods The compounds were prepared by repurification and their structures were identified by physicochemical properties and spectral analyses. Results Nine compounds were isolated and identified as ailanthone A [11?, 20-epoxy-1?, 2?, 12?-pentahydroxypicrasa-3, 13(21)-dien-16-one, Ⅰ], olean-9(11), 12-dien-3?-ol (Ⅱ), D-friedoolean-14-en-3-one (Ⅲ), ?-amyin (Ⅳ), cycloart-25-ene-3?,24?-diol (Ⅴ), hopane-3-one-22-ol (Ⅵ), n-tetratriacontane (Ⅶ), L-evonymitol (Ⅷ), D-mannitol (Ⅸ).
