Objective To study the association between pulse wave velocity and conventional atherosclerotic risk factors in patients with essential hypertension. Methods Automatic pulse wave velocity (PWV) measuring system was applied to examine carotid-femoral PWV (CFPWV) and carotid-radial PWV (CRPWV) as the parameters reflecting central elastic large arterial and peripheral muscular medium-sized arterial elasticity, respectively. Six hundred sixty four hypertensive patients aged 18-82 years (353 males and 311 females, mean age 52.1?12.8 years) were recruited. Blood pressure, fasting glucose, uric acid and cholesterol were measured. Results CFPWV and CRPWV significantly increased with the increase of the blood pressure level (both, P

The spores suspension of Streptomyces roseosporus D-38 irritated with 20mW He-Ne laser for 20 min were incubated on G1 medium plates containing 1. 9?g/mL of streptomycin. Ten percent of mutants increased the potency of daptomycin by streptomycin-resistance method, including the mutant LC-54, which could produce daptomycin 81. 2 mg/L, which was 39% higher than that of the beginning strain by flask fermentation.

OBJECTIVETo investigate the correlationship between congenital heart disease and 5, 10-methylenetetra hydrofolate reductase (MTHFR)'s C677T or folacin intakes, and to study the interaction of them in the occurring of congenital heart disease.
METHODSWe used case-control study (case = 104, control = 208) method. Cases and controls were chosen by age, sex and other conditions. The MTHFR C677T genotype distribution was analyzed by using polymerase chain reaction restricted fragment length polymorphism (PCR-RFLP), and non-conditional and multi-conditional logistic regression analysis were also used to analyze the correlationship and interaction of the factors.
RESULTSIn case group, the number of people in low folacin intake level was 38 (36.54%), which in control group was 21(10.10%). The intake level of folacin during pregnancy was related to congenital heart disease (chi(2) = 31.614, nu = 1, P < 0.0001). The value of OR was 1.417 with 95%CI 1.216 - 1.651, indicating that the low level of folacin intakes was a risk factor to the congenital heart disease. In case group, the number of TT genotype was 46 (44.24%), the number of CT genotype was 42 (40.38%), the number of CC genotype was 16 (15.38%). In control group, the number of TT genotype was 39 (18.75%), the number of CT genotype was 114 (54.81%), the number of CC genotype was 55 (26.44%). A significant genotype distribution difference was identified between case and control group (chi(2) = 23.13, nu = 2, P < 0.0001). Genotype MTHFR 677TT was a risk factor of congenital heart disease and the OR value was 3.437 (95%CI: 2.042 - 5.784). The interaction analysis suggested that the low level of folacin intakes and the MTHFR 677TT genotype had a positive adding effect in the occurring of congenital heart disease. After adjusted some factors such as the ages of parents, fetus age and sex, the effect values of interaction were 13.343 and 15.911 respectively, and the percentages of attributable interaction effects were 0.619 and 0.612. The percentages of effect values of interaction between pure factors were 0.649 and 0.637 and the population attributable risks were 25.26% and 27.82% according to the estimated exposure rate of population risk factors.
CONCLUSIONThe low level of folacin intakes during pregancy should be a risk factor to congenital heart disease and the MTHFR 677TT genotype be correlated to congenital heart disease. There is interaction between folacin intakes and the MTHFR 677TT genotype. Increasing the intakes of folacin among MTHFR 677TT genotype people might decrease the incidence rate of congenital heart disease.

Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.

OBJECTIVEThis study aimed to investigate the value of child oral health for Chengdu parents, their intentions, and factors influencing their decision to acquire oral insurance coverage for their childrens.
METHODSA total of 562 Chengdu parents were interviewed using questionnaires by convenient sampling, and the results were analyzed using SPSS 20.0.
RESULTSThe age of children (B = -1.741, P = 0.004), age of parents (B = 2.031, P = 0.003), level of oral discomfort (B = 0.569, P = 0.000), incurring/not incurring oral care expenses in the previous year (B = 1.897, P = 0.014), the last time parents' had teeth cleaned (B = 0.777, P = 0.006), and acquiring/not acquiring commercial insurance coverage (B = 1.632, P = 0.031) significantly influenced the intention of acquiring child oral insurance.
CONCLUSIONChild oral health, health and insurance awareness of parents, and other factors influenced the intention of parents to purchase oral insurance coverage for their children, which were significant to establish pediatric dental insurance.
