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 assess the change of left ventricular wall motion at ventricular pacing(VP)by using global circumferential strain (GCS) and segmental circumferential strain of speckle tracking imaging(STI). Methods Seven adult pigs were sedated,followed by median sternotomy and opening of the pericardium. Temporary pacing leads were placed on the right ventricular (RV) epicardium and LV epicardium for RV or LV pacing. A LV short axis view at the mid-level LV was acquired at sinus and VP rhythm. Analysis of circumferential strain by STI was performed offline. The onset of QRS wave was used to characterize the beginning of the cardiac cycle, and the ratio of beginning systolic time, end systolic time and total systolic time to cardiac cycle dyssynchrony was analyzed at sinus and VP rhythm. Results Compared with sinus rhythm,in VP rhythm all of the ratio of the beginning systolic time,end systolic time and total systolic time to cardiac cycle were increased (all P ＜0.05), and the construction of six segments were dyssynchrony,even segmental paradoxical movement. At VP ≥130 beats/min,both LV global and LV segments sometimes showed irregular motion while the EKG remained normal, which included: ( 1 ) multiple construction and diastole in one heart cycle; (2) A large variability of construction amplitude in several consecutive cardiac cycles. Conclusions VP can lead to several kinds of disturbance of left ventricular wall motion, including delay and lengthening of LV systole, dyssynchrony, and irregularity of systole and diastole.

OBJECTIVE: To explore the effects of laminaria japonica polysaccharides(LJP) and tea polyphenols (TP) on nasopharyngeal carcinoma(NPC) cells HONE1 and CNE2, and further to explore the underlying mechanism of antitumor activity of LJP on NPC cell in vivo. METHOD: To identify the logarithmic growth phase of NPC cells HONE1 and CNE2 through cell growth curve and doubling time by means of MTT, then inhibition of the cells proliferation were detected with LJP and TP separately and combined. With LJP treatment, cell apoptosis of HONE1 was examined by double staining assay. A tumor model,established by subcutaneously inoculation of NPC cell HONE1 into nude mice,was used to evaluate the inhibitory effect of LJP in vivo. RESULT: Both LJP and TP had inhibition effect on two groups of cell proliferation, and LJP and TP combined effect of inhibition were higher than the two separate on two sets of experimental cell proliferation, whose effect was concentration-dependent. LJP could induce apoptosis of HONE1. With the increasing concentration of LJP, apoptosis rate increased. The apoptosis rate was(49.51 +/- 1. 89) % (P<0. 01) when treated with 320 mg/L LJP. The inhibition rate was between 50% to 60% at 72 h after treatment with 320 mg/L LJP. Compared to control group, the growth of xenografts in nude mice was significantly suppressed after administration of LJP at a dose-dependent manner. The inhibition rates were 33. 7%(P<0. 05)and 47. 0%(P<0. 01) when treated with 25.0 mg/kg and 50. O mg/kg respectively. Whereas the inhibition rate of 12.5 mg/kg group was only 16. 4%(P>0. 05). CONCLUSION LJP and TP can inhibit the proliferation of NPC cells HONE1 and CNE2 respectively,and combined use has a significant effect. LJP can inhibit the growth of NPC probably by inducing apoptosis of NPC cells in vitro and in vivo.

OBJECTIVE:To study the effects of new Xianling gubao capsule on fracture healing in rats,and to provide reference for seeking new formula of"to reduce stockpiles and increase efficiency(to reduce stockpiles and constant efficiency)".METHODS:Rats were randomly divided into sham operation group(distilled water),model group(distilled water),Xianling gubao capsule group (350 mg/kg),new Xianling gubao capsule low-dose,medium-dose and high-dose groups (53,105,210 mg/kg),with 14 rats in each group. Except for sham operation group,right middle femur fracture model was established under the anesthetic state. Rats were given relevant medicine 10 mL/kg intragastrically after woken,once a day,for consecutive 4 weeks.After last administration,body weights of rats were determined;the formation of callus and histopathological changes in fracture were observed;biomechanics of fracture side(fracture stress and bone crushing force)was measured. The levels of inflammatory factors (TNF-α ,IL-1 β) in serum were detected by ELISA. RESULTS:Compared with sham operation group,body weight,fracture stress and bone crushing force of fracture side were decreased significantly(P<0.05 or P<0.01),while the serum levels of TNF-α and IL-1 β were increased significantly(P<0.01). In model group,the scab was visible around the fracture,and the trabecular bone was not mature and arranged in confusion. Compared with model group,body weights of rats were increased significantly in new Xianling gubao capsule high-dose group and Xianling gubao capsule group (P<0.05);fracture stress of fracture side were increased significantly in new Xianling gubao capsule medium-dose and high-dose groups and Xianling gubao capsule group(P<0.05 or P<0.01). The serum levels of TNF-α and IL-1β were decreased significantly(P<0.01). There was no statistical significance in above indexes among new Xianling gubao capsule groups and Xianling gubao capsule group(P>0.05).The area of the callus in each group was smaller;the fracture line became blurred;the fracture trace disappeared and the number of bone trabeculae increased. The cortical layer was thickened,and a large number of capillary implants were found in the bone marrow cavity. CONCLUSIONS:New Xianling gubao capsule has a significant role in promoting fracture healing,and can effectively improve the strength of bone biomechanics and inhibit the inflammatory reaction.

Objective: To investigate the regulation of emodin on microRNA expressions in mouse model with sepsis by GeneChip microRNA array. Methods: Forty two c57 mice were randomly (random number) divided into 3 groups: sham operation group (sham group, n=14),sepsis group(n=14) and emodin group (n=14). The sepsis model of the mouse was subjected to cecal ligation and puncture (CLP). Mice in emodin group received intraperitoneal injection of emodin (40 mg/kg) half an hour before operation and every 12 hours after CLP. All mice were sacrificed 48 h after surgery and part of the ileum were removed for intestine tissue stained with hematoxylin eosin. The levels of tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6) and intestinal fatty acid binding protein (I-FABP) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA). Total RNA of ileum tissues was extracted from the sepsis group and emodin group, and then subjected to miRNA microarray. The results of microarray were further verified by quantitative real-time PCR (qRT-PCR). Target genes of differentially expressed miRNAs were predicted and subjected to gene ontology (GO) and KEGG pathway enrichment analysis. Data of multi-groups were analyzed by one way variance (ANOVA) and inter-group comparisons were made by SNK-q tests. Mann-Whitney U test was used when homogeneity of variance were not met. The value of P<0.05 was considered statistically significant. Results: Compared to the sepsis group, the levels of serum TNF-α, IL-6 and I-FABP in the emodin group were decreased significantly. MiRNA microarray showed that 23 miRNAs were differentially expressed in the emodin group as compared to the sepsis group, among which 17 miRNAs were up-regulated and 6 miRNAs were down-regulated. qRT-PCR results were consistent with miRNA array data. Target genes of 10 selected miRNAs were predicted and subjected to bioinformatic analysis. A total of 3 410 target genes were significantly enriched in 2 072 GO biological process terms, 246 GO cellular component items and 277 GO molecular function terms. Moreover, KEGG pathway analysis showed that these differential miRNAs were involved in the regulation of PI3K-Akt signaling pathway, MAPK signaling pathway, and TNF signaling pathway. Conclusions Emodin can regulate the expression of multiple microRNAs, and play an important role in protecting the intestinal mucosal barrier via a variety of targets and pathways.
