BACKGROUND:Individuals with different vertical facial types have different chin morphologies. For the individuals with different vertical facial types, what is the most beautiful chin morphology?
OBJECTIVE:To evaluate the effects of vertical facial types and chin morphology on facial profile attractiveness.
METHODS:Three beautiful females were selected, including one with high mandibular angle, one with average angle and one with low angle. Their facial profile photographs were taken. A series of new pictures were generated by the smal scale (2 mm per unit) modification of soft tissue chin in the sagittal direction and vertical direction. Raters consisting of 17 orthodontists and 35 laypersons were selected for aesthetic ratings, in order to evaluate the facial profile attractiveness of the individuals with different vertical facial types.
RESULTS AND CONCLUSION:There was no esthetic difference of vertical change in female with high angle;while slightly protrude chin was perceived to be more beautiful than retruded chin. For the female with average angle, lower chin was more attractive than higher chin;slightly protruded chin was beautiful than excessive protruded chin and retruded chin. For the individual with low angle, higher chin was preferred by raters;slightly protruded chin was more beautiful than excessive protruded chin and retruded chin.The results indicate that the effects of vertical facial types and chin morphology to facial profile attractiveness are different. In clinical orthodontic, vertical facial types should be taking into consideration to change the chin morphology of the patents, in order to obtain better profile attractiveness.

OBJECTIVETo evaluate the inhibitory effect of genistin combined with anastrozole on the growth and apoptosis of breast tumor tissue, and to study their anti-cancer mechanism by using the model of 7,12-dimethylbenz [alpha] anthracene (DMBA)-induced mammary tumors following ovariectomy in Sprague-Dawley (SD) rats.
METHODSThe DMBA induced postmenopausal SD rats were randomly divided into the control group, the genistein group, the anastrozole group, and the genistein combined with anastrozole group. The growth of tumors was observed in each group. The proliferation index and apoptosis index of tumor cells were determined. Moreover, estradiol (E2) and 17beta-HSD1 mRNA levels were determined by ELISA and RT-PCR respectively.
RESULTSThe tumor growth was inhibited in the genistein group and the anastrozole group. The inhibitory ratio was significantly higher in the genistein combined with anastrozole group (P < 0.05). Compared with the control group, levels of E2 and 17beta-HSD1 mRNA decreased more significantly in the genistein combined with anastrozole group (P < 0.05).
CONCLUSIONSGenistein could suppress the growth of mammary tumors in postmenopausal rats. It showed synergistic effect when combined with anastrozole, which resulted in reduced levels of E2 and 17beta-HSD1 mRNA. It had inhibitory effect on the growth of breast tumors.

BACKGROUND: Current studies on CD62P have focused mainly on cardiovascular diseases, while only few studies have evaluated the effects of CD62P on the development of sepsis and the association between endothelial cell injury with inflammation and coagulation. This study attended to explore the association between endothelial cell injury with inflammation and coagulation by evaluating the expression of soluble CD62P (s-CD62P) in plasma and its mechanism in patients with sepsis, thus to provide the evidence of effective treatment of sepsis with anti-adhesion therapy targeted CD62P. METHODS: A total of 70 critically ill patients with systemic inflammatory response syndrome (SIRS) admitted to intensive care unit (ICU) between September 2009 and February 2010 were enrol ed for a prospective and control study. According to the diagnostic criteria of sepsis/SIRS, the patients were divided into two groups: a sepsis group (n=38) and a SIRS group (n=32). Another 20 healthy volunteers served as a control group. Patients in the sepsis group and SIRS group were matched by clinical signs of high blood pressure, diabetes and its complications. The demographics of the patients including age, sex, body mass index (BMI), smoking and alcohol addict were compared among the groups. Six mL peripheral blood samples were collected within 24-hour admission in ICU for enzyme-linked immunosorbent assay (ELISA) to detect the plasma levels of s-CD62P, TNF-α, and hs-CRP. And variables of coagulation function such as platelet (PLT), prothrombin (PT), activated partial thromboplastin time (APTT), D-dimer and antithrombin-III (AT-III) were analyzed during 24 hours after admission to ICU. Meanwhile sequential organ failure assessment (SOFA) score of critically ill patients was evaluated. Data were expressed as mean±standard deviation and were statistical y analyzed by using SPSS 17.0 statistical software. The differences in plasma levels of s-CD62P of patients in each group were analyzed by ANOVA and the Kruskal-Wallis test. The relations between s-CD62P and inflammatory cytokines as well as with coagulation were determined by Pearson's product moment correlation coefficient analysis. Changes were considered as statistically significant if P value was less than 0.05. RESULTS: Compared with the control group and SIRS group, the sepsis group demonstrated significantly higher levels of s-CD62P, TNF-α and highly sensitive C-reactive protein (hs-CRP) (P<0.05). The plasma levels of D-dimer, PT, and APTT in the sepsis and SIRS groups were significantly higher than those in the control group, while the platelet count and the activity of AT-III were obviously lower (P<0.05). In the sepsis group, the plasma levels of hs-CRP and TNF-α were positively correlated with PT, APTT, and D-dimer, and negatively correlated with AT-III and PLT (P<0.05). The plasma levels of s-CD62P were significantly correlated with the plasma levels of TNF-α, hs-CRP, D-dimer, PT, and APTT, whereas they were correlated negatively well with PLT and AT-III (P<0.05). CONCLUSIONS: The concentration of plasma s-CD62P is elevated as a early biomarker in patients with sepsis, and it serves as one of the pathogenic factors responsible for endothelial cell damage. Coagulation and mediators of inflammation promote each other, aggravating the severity of sepsis. Plasma s-CD62P may be an important factor for the development of coagulation and inflammatory reaction.

Objective To assess the capability of the colon computer-aided-detection(CAD) for the detection of colonic neoplasm on low-dose CT colonography with changing sphericity filter values. Methods Low dose (50 mA) CT colonography data from 56 patients with 159 colonic neoplasms confirmed by conventional colonoscopy and surgery were divided into four groups: colorectal cancer, ≥ 10 mm polyps,5. 1 to 9. 9 mm polyps and ≤ 5.0 mm polyps. The golden standard was established by matching the neoplasms on CT colonography images. The datasets analyzed subsequently by the Colon CAD system at four discrete sphericity filter settings (SFV): 0. 25, 0. 50, 0. 75 and 1.00. The location and size of highlight lesions by the colon CAD were recorded. Comparison was made with the known golden standard in order to determine the detective rate of colonic neoplasms. Chi-square tests were used to compare the detection rates of four groups by CAD SFV at four settings. Results Fifty six patients had 159 colonic neoplasms including 44 colonic cancers, 45 large polyps (max diameter≥ 10. 0 mm), 32 median polyps (max diameter 5. 1 to 9. 9 mm) and 38 small polyps ( max diameter ≤5.0 mm). The colon CAD had the detective rate of 85.5%( 136/159), 85.5% ( 136/159 ), 79. 2% ( 126/159 ) and 56. 0% (89/159) for all colonic neoplasms at four sphericity filter settings 0. 25, 0. 50, 0. 75 and 1.00 respectively. There was statistically significant difference between the sphericity filter settings at 0. 25 and 1.00 ( P < 0. 05). Detective rate was highest at lower sphericity, false-positive rate increased at same time, however, 91.4% ( 138/151 )to 93.9% (31/33 )of false-positives were rapidly dismissible with 2D axial images, only 6. 1% (2/33)to 8.6% (13/151)of false-positives needed to discriminate with multiplanar reconstruction or 3D virtual colonoscopy. Conclusion The Colon CAD system can detect colonic neoplasms satisfactorily in low dose CT colonography and may satisfy the needs of radiologists with different experience by changing sphericity filter settings.

This study was aimed to evaluate the clinical effect and safety of Chinese medicine treatment of lumbar disc herniation with qi-tonifying, stasis-resolving and kidney-tonifying method. The randomized con-trolled trial (RCT) was applied in the study to evaluate the clinical effect of qi-tonifying, stasis-resolving and kidney-tonifying method in the treatment of lumbar disc herniation . A total of 122 lumbar disc herniation pa-tients were randomly divided into the treatment group ( n = 61 ) and the control group ( n = 61 ) . Chinese medicine treatment with the qi-tonifying, stasis-resolving and kidney-tonifying method was applied in the treatment group . And Celecoxib and Methycobal were orally administered in the control group . Then , the VAS scores, JOA scores, Oswestry disability index (ODI) were recorded and analyzed pre-treatment, four weeks af-ter treatment and the twelfth week of follow-up in order to evaluate the clinical effect . Adverse reactions were also observed and recorded at the same time to give a comprehensive evaluation on its safety . The results showed that there were no significant differences between the treatment group and control group in the baseline data before treatment . Hence , data from two groups were comparable . Compared with pre-treatment , the VAS scores and ODI scores were obviously reduced in both groups after four-week treatment . The JOA scores were increased obviously ( P < 0 . 05 ) . There were no statistical differences on ODI scores and JOA scores between two groups . The VAS scores of the treatment group were obviously higher than the control group ( P < 0 . 05 ) . In the twelfth week of follow-up , the VAS scores , ODI scores and JOA scores had increasing tendency in
both groups . There were no statistical differences between two groups . There were no statistical differences on the total effective rate between two groups . In the treatment group , four patients received surgery , four cases lost to follow-up , and four cases with mild adverse event . In the control group , six patients received surgery , three cases lost to follow-up , and two cases with mild adverse event . It was concluded that the RCT of Chi-nese medicine treatment of lumbar disc herniation with q i-tonifying , stasis-resolving and kidney-tonifying method received same clinical effect as the combination of Celecoxib and Methycobal . The Chinese medicine treatment can effectively relieve pain degree of lumbar disc herniation , improve function of the lumbar vertebrae and improve the daily life and social activity ability of patients. The short-term follow-up effects were con-firmed . However , the long-term efficacy still requires further study .
