OBJECTIVETo analyze the asymmetry of measurements in facial asymmetry patients with skull positioning posterior-anterior radiographs after orthodontic-orthognathic treatment.

METHODSPosterior-anterior cephalometric radiography and cephalometric analysis were performed in forty-five patients with different degrees of facial asymmetry. A single sample t-test was conducted to compare the asymmetry of measurements before treatment and individual normal occlusion. The measurement and reference values in facial asymmetry patients who underwent orthodontic-orthognathic treatment were summated by analyzing the correlation coefficient. The paired t-test was employed to compare the difference between the two groups before and after the treatment.

RESULTSFourteen measurements were significantly different before the treatment and individual normal occlusion (P < 0.05). Me[X] exhibited a higher correlation index of Ag[X] in forty-five cases. Twenty-eight patients showed the main asymmetry in the mandibular body, whereas fifteen patients in the ramus. Two patients showed the main asymmetry in both mandibular body and ramus. Fifteen measurements were significantly different before and after the treatment (P < 0.05).

CONCLUSIONFacial asymmetry is mainly concentrated in one-third of the surface, primarily manifested in the mandibular body. Orthodontic-orthognathic treatment is preferred when Ag[X] is greater than the minimum reference value of 11.31%, Go[X] is greater than 9.79%, and Me[X] is greater than 5.2 mm.

Cardiovascular disease, with high morbidity and mortality, has been threatening the health of human beings. Therefore, expecting to find a more effective therapeutic method, a plenty of researchers devote themselves to the study of the cardiovascular disease all the time. Since discovered on the heart, M3 receptor of muscarinic acetylcholine receptor (mAchR, M receptor) became a new starting point of the research of the cardiovascular disease. With more and more investigation, many people found that M3 receptor could protect the heart from kinds of cardiovascular disease, which may make it a new hopeful therapeutic point. So, expecting to give support to the reference and encouragement for the study of disease related to M3 receptor in future, this review expounds M3 receptor on the heart from the main following aspects: the effect on the heart, the influence on the cardiovascular disease and the mechanism of M3 receptor involved.

Objective To observe the expression of SGK in decidua in patients with unexplained recurrent spontaneous abortion(URSA) and to investigate its role in the course of apoptosis.Methods The expression of SGK was detected by immunohistochemistry in decidua of URSA(abortion group,n =50) and normal first trimester pregnant women(control group,n =30).The apoptotic index was detected by TUNEL.Results Compared with the control group,the positive expression of SGK decreased significantly in the abortion group,and the difference was statistically significant(x2 =6.78,P ＜ 0.05).The average apoptotic index of the abortion group was (8.19 ± 3.58) ％,which was significantly higher than (2.87 ±1.07)％ of the control group(t =7.94,P＜0.05).Conclusion Intensive apoptosis,the decreasing positive expression rate of SGK in decidua cells may play critical roles in URSA.

Seasickness is a leading factor causing reduction in battle efficiency, and psychological factor is one of the important factors influencing the development and progression. This article reviews the mechanism, affecting factors, predictive indications, prevention and treatment of seasickness from a psychological perspective, in an attempt to provide psychological guidelines for military training, enhance the anti-seasickness ability of military staff and decrease its incidence.

Objective: To evaluate the effect of core∶dentin thickness ratio on the flexure strength, fracture mode and origin of bilayered IPS Empress Ⅱceramic composite specimens. Methods: IPS EmpressⅡ core ceramic, dentin porcelain and bilayered composite specimens with core∶dentin thickness ratio of 2∶1 and 1∶1 were tested in three-point flexure strength. Mean strengths and standard deviations were determined. The optical microscopy was employed for identification of the fracture mode and origin. Results: The flexure strength of dentin porcelain was the smallest (62.7 MPa), and the strength of bilayered composite specimens was smaller than single-layered core ceramic(190.2 MPa). The core∶dentin ratio did not influence the strength of bilayered composite specimens. The frequency of occurrence of bilayered specimen delaminations was higher in the group of core∶dentin thickness ratio of 1∶1 than in the group of 2∶1. Conclusion: IPS Empress Ⅱcore ceramic was significantly stronger than veneering dentin porcelain. Core∶dentin thickness ratio could significantly influence the fracture mode and origin, and bilayered IPS Empress Ⅱceramic composite specimens showed little influence in the fracture strength.
