ObjectiveTo investigate the clinicopathological features, diagnosis and treatment of invasive micropapillary carcinoma (IMPC) of the breast.MethodThe relevant literatures at home and abroad in recent years about the clinical features, pathological features and diagnosis and treatment of IMPC were reviewed.ResultsIMPC is in low incidence and mostly in mixture. Because the clinical manifestations of IMPC and invasive ductal carcinoma of breast are basically similar, only the typical pathological features in pathological examination can confirm the diagnosis as " inside-out growth pattern” and " morula-like clusters of cancer cells surrounded by clear stromal spaces”.ConclusionsIMPC is a special subtype of breast invasive carcinoma, which should be pay enough attention to it in clinic due to its unique microscopic morphology, high vessel invasiveness and high lymph node metastasis rate, high malignancy, poor prognosis and so on.
Hydrogel is a kind of degradable hydrophilic polymer, but excessive hydrophilicity leads to larger volume, lower elastic modulus and looser structure, which further affect its use. Especially in the field of biomedical engineering, excessive swelling of the hydrogel can compress the nerves and improve degradation rate resulting in mismatch of tissue growth and released ions. Therefore, anti-swelling hydrogel has been a research hotspot in recent years. This paper reviews the recent research progress on anti-swelling hydrogel, and expounds the application mechanism and preparation method of hydrogel in biomedical engineering, aiming to provide some references for researchers in the field of anti-swelling hydrogel.
目的 探讨伴颞下颌关节紊乱病（TMD）的成人正畸患者的心理社会因素。 方法 2009年5月－2011年12月伴TMD的成人正畸患者42例为观察组，无矫正要求、伴TMD的错牙合患者50例为对照组。采用九十项症状清单（SCL-90）、艾森克人格问卷（EPQ）进行测试，同时进行TMD调查。 结果 观察组与对照组相比，得分较高的有强迫、焦虑、抑郁、人际关系敏感等因素，差异有统计学意义（P＜0.05）；观察组患者P量表、N量表得分高于对照组，差异有统计学意义（P＜0.05）。 结论 伴TMD的成人正畸患者心理健康问题普遍存在,倾向于神经质和精神质的人格特征。
