OBJECTIVETo observe the effect of rosuvastatin on left ventricular cardiac function, arteriosclerotic plaque and high sensitive C-reactive protein (hs-CRP) in hypertensive patients with mild elevation of LDL-C.

METHODSSeventy-nine patients with a SBP of 140-179 mmHg and/or a DBP of 90-109 mmHg and mild elevated LDL-C were treated with rosuvastatin for 12 months (n=40) or not (n=39). The changes of hs-CRP, arteriosclerosis plaque and cardiac function at the end of the 12-months treatment relative to the baseline levels were analyzed.

RESULTSAfter 12 months of treatment, LDL-C was decreased by 33.2% in rosuvastatin group but remained unchanged in patients without rosuvastatin treatment. The left ventricular peak filling rate (LVPFR) increased significantly from 1.85 to 2.59 (P<0.05) and the serum levels of hs-CRP reduced significantly (P<0.05) after rosuvastatin treatment. The size of the plaques reduced significantly after a 12-month rosuvastatin therapy.

CONCLUSIONRosuvastatin therapy on the basis of conventional anti-hypertensive drugs can obviously improve the left ventricular diastolic function and produce favorable effects on arteriosclerotic plaques.

PURPOSEThis study aims to explore the biomechanical mechanism of lower limb injuries to the driver by establishing a finite element (FE) simulation model of collisions.

METHODSFirst a minibus FE model was integrated with a seat belt system. Then it was used to rebuild two collisions together with the total human model for safety (THUMS) provided by Toyota Motor Corporation: a rear-end collision between a minibus and a truck and a head-on collision of a minibus to a rigid wall. The impact velocities of both collisions were set at 56 km/h. The vehicle dynamic response, vehicle deceleration, and dashboard intrusion in the two collisions were compared.

RESULTSIn the minibus rear-end truck collision, the peak values of the von Mises equivalent stress at the tibia and the femur were 133 MPa and 126 MPa respectively; while in the minibus head-on rigid wall collision, the data were 139 MPa and 99 MPa. Compared with the minibus head-on rigid wall collision, the vehicle deceleration was smaller and the dashboard intrusion was larger in the minibus rear-end truck collision.

CONCLUSIONThe results illustrate that a longer dashboard incursion distance corresponds to a higher von Mises equivalent stress at the femur. The simulation results are consistent with the driver's autopsy report on lower limbs injuries. These findings verify that FE simulation method is reliable and useful to analyze the mechanisms of lower limb injuries to the driver in minibus frontal collisions.

Three-dimensional ordered porous carbon materials exhibit potential application prospects as excellent drug supports in drug delivery systems due to their high specific surface area, tunable pore structure, and excellent biocompatibility. In this study, three-dimensional ordered porous carbon materials were prepared using Acanthopanax senticosus herbal residues as raw material and KOH as activating agent through a one-step pyrolysis method. The prepared carbon-based material was systematically characterized by powder X-ray diffraction, scanning electron microscopy, N₂ adsorption-desorption and Fourier-transform infrared spectroscopy. The results show that the three-dimensional ordered porous carbon materials prepared with KOH as the activator via pyrolysis possess abundant functional groups, high porosity, and high specific surface area, with a specific surface area of 1 471.6 m²·g^-1. The three-dimensional ordered porous carbon materials prepared at 800 ℃ exhibits a high drug loading capacity (78.0%) and drug release rate (86.8%) for 5-fluorouracil. Three-dimensional orderly porous carbon materials show significant application advantages in drug construction, and their high specific surface area and adjustable pore size structure significantly improve the drug load rate and drug release rate, providing a solid foundation for the development of efficient and accurate drug delivery system.

OBJECTIVETo investigate the possible effects and roles of bodyweight on the puberty onset in adolescent girls.

METHODSTotally 288 Chinese female children and adolescent girls aged 5 to 16 were followed up yearly for four consecutive years. The height, bodyweight, fat percentage, sexual characteristics, and the serum levels of leptin and insulin-like growth factor-1 (IGF-1) were studied to analyze the influential factors of puberty onset and age of menarche.

RESULTSThe serum level of leptin elevated significantly from age 13 [(9.23 +/- 1.25) microg/L] and reached peak at age 16 [(13.19 +/- 1.45) microg/L]. IGF-1 significantly correlated with the timing of puberty onset (r = 0.292, P = 0.016). BMI and fat percentage had no significant effects on the onset of puberty, but were negatively correlated with the age of menarche (r = -0.323, P = 0.037, r = -0.298, P = 0.038 respectively).

CONCLUSIONBodyweight may have effect on puberty onset in female adolescents.
