Objective To evaluate the effects of pulsed ultrasound at different intensities on the healing of standardized contusions in an animal model. Methods Forty-eight 3-month-old, male Sprague-Dawley rats were given experimental contusions of the right gastrocnemius muscle before being divided into four groups randomly ( n =12 in each group): (1) a muscle injury control group (muscle injury without treatment); (2) a muscle injury and pulsed ultrasound (0.25 W/cm2 ) group; (3) a muscle injury and pulsed ultrasound ( 0.5W/cm2 ) group; and (4)a muscle injury and pulsed ultrasound ( 0.75 W/cm2 ) group. Pulsed ultrasound treatment ( frequency 3 mega Hz)was started 24 hours post injury and delivered 5 min daily for 14 days on the injured right hindlimb. At days 4, 7 and 14 after injury, muscle samples were analyzed through hematoxylin-eosin staining and immunohistochemistry for the detection of muscle satellite cells and desmin. Results The average optical density (IOD) of desmin-positive mononucleated cells had increased significantly at days 4, 7 and 14 post injury in the treatment groups compared to the control group, but with no statistically significant difference among the 3 ultrasound treatment groups. Conclusions The pulsed ultrasound treatment played a beneficial role in skeletal muscle regeneration after contusion. There was no significant dose-dependent effect over the intensity range of 0.25-0.75 W/cm2.

Objective To survey the knowledge of the Urumqi population in Xinjiang on the awareness and the protection of ultraviolet (UV) irradiation.Methods Three hundred and twentyfour subjects from Urumqi were investigated with a questionnaire about the basic knowledge of UV,the UV protection methods,the awareness and application of sunscreens,and the channels through which they acquired the knowledge.Results A total of 324 subjects completed the questionnaire.Only 78.0％ knew the harmful effects of UV,62.0％ of them knew that UV could lead to skin photo-aging,and 54.9％ knew that UV irradiation could cause skin cancer.Sunscreens were the main choice for UV protection (58.0％).Regarding sunscreens,38.3％ subjects knew the meaning of SPF,and only a small percentage of subjects (17.3％) were aware of the meaning of PA.About 25.3％ of subjects applied sunscreens every day,43.2％ used sunscreens sometimes,and 18.5％ did not use it at all.The main factor of choosing sunscreens was brand popularity and the main information sources to get the knowledge of UV and UV protection were TV advertisements.Conclusions This study shows that the knowledge of UV and UV protection of the Urumqi population is acceptable,but the protections are insufficient,which should be strengthened and guided through dermatologists and multiple media.

Objective:To establish an in vitro capsular bag model and compare the inhibitory effects of different 360° square-edge intraocular lens (IOL) on lens epithelial cells (LECs) migration. Methods:In vitro capsular bag model with posterior capsule opacification (PCO) was established using Transwell compartment, cell climbing slices, human collagen type Ⅳ, and IOL.The models were divided into Plate-loop HydroSmart group, C-loop HydroSmart group, and C-compensation-loop Hydrophobic group according to the different square-edge IOL implanted.A blank control group was set using the Transwell compartment without IOL.The early PCO pathological manifestations in lens epithelial cell line SRA01/04 cultured in the Transwell compartment were observed with an inverted microscope.The cell morphology in different groups was observed by hematoxylin and eosin staining.The cell counting and cell migration inhibition rate of anterior capsule and posterior capsule were calculated by Transwell assay and cell-exclusion zone assay, respectively. Results:The early pathological characteristics of PCO, such as early Soemmering ring and small Elschnig pearl, could be found in cells in the in vitro capsular bag model after 48-hour culture.The migrating cells in model groups were fibrous.No changes mentioned above were found in blank control group.The number of migrating cells in the anterior capsule of Plate-loop HydroSmart group, C-loop HydroSmart group, C-compensation-loop Hydrophobic group was 18.80±5.53, 24.67±9.80, and 34.47±10.80, respectively, and the number of migrating cells in the optical area of the posterior capsule of the three groups was 56.43±9.00, 162.20±16.38, and 121.30±12.01, respectively.The cell migration inhibition rate in the anterior capsule of Plate-loop HydroSmart group, C-loop HydroSmart group, C-compensation-loop Hydrophobic group was (92.02±1.94)%, (89.76±3.10)%, (86.27±4.54)%, respectively, and the cell migration inhibition rate in optical area of the posterior capsule of the three groups was (91.60±3.65)%, (70.14±5.35)%, (78.43±3.48)%, respectively.The number of migrating cells in the anterior capsule was lower and the cell migration rate inhibition was higher in Plate-loop HydroSmart group than C-compensation-loop Hydrophobic group, with significant differences (both at P<0.05). The number of migrating cells in the optical area of the posterior capsule and the cell migration inhibition rate was greater than those of C-loop HydroSmart group and C-compensation-loop Hydrophobic group, showing statistically significant differences (all at P<0.001). Conclusions:The in vitro capsular bag model can be used in PCO research.Compared with C-loop HydroSmart IOL and C-compensation-loop Hydrophobic IOL, Plate-loop HydroSmart IOL can more effectively inhibit the migration of LECs to the optical area of the posterior capsule.

The drug formulation design of self-emulsifying drug delivery systems (SEDDS) often requires numerous experiments, which are time- and money-consuming. This research aimed to rationally design the SEDDS formulation by the integrated computational and experimental approaches. 4495 SEDDS formulation datasets were collected to predict the pseudo-ternary phase diagram by the machine learning methods. Random forest (RF) showed the best prediction performance with 91.3% for accuracy, 92.0% for sensitivity and 90.7% for specificity in 5-fold cross-validation. The pseudo-ternary phase diagrams of meloxicam SEDDS were experimentally developed to validate the RF prediction model and achieved an excellent prediction accuracy (89.51%). The central composite design (CCD) was used to screen the best ratio of oil-surfactant-cosurfactant. Finally, molecular dynamic (MD) simulation was used to investigate the molecular interaction between excipients and drugs, which revealed the diffusion behavior in water and the role of cosurfactants. In conclusion, this research combined machine learning, central composite design, molecular modeling and experimental approaches for rational SEDDS formulation design. The integrated computer methodology can decrease traditional drug formulation design works and bring new ideas for future drug formulation design.
