Myoepithelial carcinoma is a rare malignant tumor. The primary site of this tumor is the salivary glands. With the rapid ad-vancement in immunohistochemical examination and pathological examination, the number of clinical cases of the most common type of myoepithelial carcinoma of the salivary glands, as well as rare primary sites of myoepithelial carcinoma, reported in the litera-ture has increased. Based on related cases reported in the literature, various studies worldwide, and our personal practical experience, this article summarized advancements in the research on myoepithelial carcinoma, including etiology, pathology, clinical characteris-tics, diagnosis, and treatments, as well as myoepithelial carcinoma features of various rare primary sites. This article aims to provide useful evidence for oncologists in diagnosing and treating myoepithelial carcinoma.

ObjectiveTo investigate the influence of transverse and longitudinal lower segment caesarean section on the outcome of newborn, postpartum haemorrhage and ratio of complications in placenta previa. MethodsPlacenta previa with lower segment transverse caesarean section( 117 cases) were taken as control group, meanwhile, the lower segment with longitudinal section (142 cases ) as experimental group. Their operational complications, amount of bleeding during and after operation and outcome of the perinatal period were analysed.Results No significant difference in age, parities, gestational weeks, the types of the placenta praevia and the locus of placenta between the two groups were found( P>0.05), while there were significant difference in the amount of bleeding during and after operation, the need of using gauze ribbon to stop bleeding, section splitting and rate of hysterectomy after caesarean section(P<0.01). ConelusionLower segment longitudinal caesarean section in placenta praevia not only shows less bleeding during operation and lower rate of postpartum haemorrhage, but also avoids using gauzes to stop bleeding and causes lower rate of hysterectomy after caesarean section, so it can be the first choice when determining the style of section in placenta praevia.

Objective To study the regularity of occurrence and development in the elderly with AAA. Methods Twenty-seven elderly cases with abdominal aortic aneurysm(AAA) were analyzed and followed up with ultrasound for ten years. Results The AAA diameters were 2.5 ~6.6 cm,with the average in crease of(0.14 ? 0.01) cm/ year. Intraluminal thromi(ILT) were found in 63.0% of all the patients. ILT were found(3.9?2.0 ) years after the AAA diagnosis with the average in crease of(0.21 ? 0.05)cm / year. Conclusions The size of AAA in the elderly is slowly enlarged to varying degree with ageing. ILT are found in more than half of all the patients. A few cases of AAA are found ruptured and a few cases of ILT exfoliated.

Objective To analyze the correlation between subjective symptoms and function of nasal ventila-tion in nonallergic rhinitis with eosinophilia syndrome ( NARES) ,in order to provide the basis for the clinical diagno-sis.Methods 44 patients with NARES were selected as the NARES group ,and 50 healthy people were selected as the control group at the same time .The total nasal resistance ( TNR ) , MCA of the two groups were compared , and Pearson or Spearman correlation was used to analyze the subjective symptoms and objective test indexes in patients with NARES.Results Before contraction,the TNR values of NARES group in 75Pa and 150Pa were higher than those of the control group (Mann-Whiteny Z=7.365,8.125,all P<0.05).After contraction,the differences of TNR values in 75Pa and 150Pa,MCA,the correlation analysis in 8 subjective symptoms and 7 objective index of NARES had no statistically significant differences between the two groups ( all P >0.05).Conclusion The correlation between subjective symptoms and function of nasal ventilation in NARES patients is not obvious .Clinical diagnosis should be comprehensive ,in case of missed diagnosis and misdiagnosis .
