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 explore the effect of big strain rhodiola injection on levels of leptin and leptin receptor mRNA in serum and liver of rabbit with fatty liver.Methods 120 healthy adult male New Zealand white rabbits were grouped with a random number table method.30 rabbits with normal diet for eight weeks in normal group;90 rabbits in fat group were fed with high fat diet for four weeks to prepare fatty liver model in which 30 rabbits were fed with high-fat diet for four weeks as model group,30 rabbits with high-fat diet and glyburide metformin tablets [150 mg/(kg·d)]for 4 weeks as control group,30 rabbits with high-fat diet and big strain rhodiola injection [40 mg/(kg·d)]for four weeks as experimental group.After the test, levels of serum leptin,hepatic leptin,expression levels of leptin receptor mRNA and levels of liver index were compared among groups.Results Serum leptin and liver leptin in experimental group and control group were all increased to varying degrees,and the serum leptin level [(4.51 ±1.17)ng/mL],liver leptin level [(6.43 ±1.93)ng/mL]of experimental group was lower than that of control group respectively,in which the serum leptin was (7.36 ±1.26)ng/mL and liver leptin was (12.33 ±3.27)ng/mL (P<0.05).Serum leptin and leptin liver receptor mRNA in experimental group and control group were all increased to varying degrees,and the serum leptin mRNA level (0.98 ±0.15),liver mRNA level (1.78 ±0.33)of experimental group was lower than that of control group,in which the mRNA level of serum leptin was (2.57 ±0.29)and liver leptin mRNA levels was (3.31 ±0. 26)(P<0.05).Levels of liver index in experimental group and control group were increased,and liver index of experimental group [(3.98 ±0. 13)%]was lower than that in control group [(4.77 ±0.20)%],and the difference was statistically significant (P<0.05).Conclusion Big strain rhodiola injection could significantly reduce leptin levels in serum and liver of rabbits,reduce expression the leptin receptor mRNA levels and improve liver index,which has guiding significance for the treatment of fatty liver.

[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). Conclusion Among them Ⅱ- Ⅸ are isolated from the plants of Ailanthus Desf. nom. Conserv. for the first time.

Four compounds were isolated from the fruit of Panax quinquefolius L. , They were iden-tified as 20 (R)-ginsenoside-Rg3( Ⅲ ), ginsenoside-Ra1( Ⅱ ), pseudo ginsenoside-RTs (iⅣ) and a new com-pound named quinquetriose ( Ⅰ ). Its structure was established as β3-D-xylopyranosyl-(1→6)-α-D-glucopy-ranosyl (1→6)-β-D-glucopyranoside, on the basis of chemical and spectroscopic evidences.

Clinical data of one patient diagnosed as IgG4-related retroperitoneal fibrosis was analyzed.IgG4 and retroperitoneal fibrosis were used as the key words to search literatures from PubMed and Wanfang Database.Clinical data of 27 cases with IgG4 retroperitoneal fibrosis,including clinical manifestation,diagnostic basis,therapeutic method and prognosis,which were retrieved through literatures,were analyzed.A 82-year-old male patient presented with urinary tract obstruction and renal insufficiency.Imaging examination revealed a retroperitoneal irregular lump shadow,and showed chronic inflammation of soft tissues in posterior peritoneum with fibrosis by biopsy pathology.The IgG4-positive plasmocyte infiltration was found by immunohistochemical method.The serum level of IgG4 was significantly increased,which was in accord with IgG4-related retroperitoneal fibrosis.After treatment with methylprednisolone,retroperitoneal lump shadow was obviously dissipated.The serum level of IgG4 became normal.27 cases with IgG4-related retroperitoneal fibrosis were searched through literature retrieval,with 19 confirmed cases,3 suspected cases,and 5 suspicious cases.Male accounted for 92.6％ (25/27),and the average age was 67.6 years old.The cases with the involvement of extraperitoneal organs accounted for 37.0％ (10/27).The misdiagnosis rate was 55.6％ (15/27).23 cases took effective therapy with glucocorticoids.IgG4-related retroperitoneal fibrosis is an orphan disease,which can be misdiagnosed easily.The diagnosis is made with histopathological examination and determination on the serum level of IgG4.The therapy with glucocorticoids is effective.
