BACKGROUND:Cilium is an antenna-like organele that plays a vital role in al organs generation and maintenance.Ciliopathiesrefer tomultisystem diseasescaused bydisordersofthecilia structure and function. OBJECTIVE:To introduce current understanding of the structure and function of the cilium,with afocus on the study progress ofciliopathies. METHODS:PubMed databasewas searched by computerusing the keywords of“primary cilium, motion cilium,ciliopathy”.Totally 371 relevantarticlespublished from 1959 to 2015 were retrieved. After excluding repetitive and irrelevant articles,we enrolled32 English literaturesregardingcilia structure, functionand ciliopathiesin accordance with the inclusion criteria. RESULTS AND CONCLUSION:Ciliopathiesalmostinvolve every system of the human body, such asthe brain, eyes, liver, kidney, bone and reproductive system.Most ciliopathies are related to human developmental or degenerative diseases, which characterized by wide-ranging clinical and genetic heterogeneity,such asprimary ciliary dyskinesia,ploycystic kidney disease, infertility, blindness and tumor. In view ofthemedical importanceof the cilium, scholars have devoted tostudyingthe underlying celular mechanisms.Thesein turnhave revealed thatciliopathiesare not only caused bydefectiveassemblyof the cilium,but also by impaired ciliarysignaling.

Background: The clinical manifestations of some rare diseases of the stomach are nonspecific, which may lead to missed diagnosis, misdiagnosis, and delayed or inappropriate management. Aims: To investigate the clinicopathological features and immunohistochemistry of some rare diseases of the stomach and their application in diagnosis and differential diagnosis. Methods: Gastroscopic biopsy specimens from Jan. 2017 to Dec. 2017 at the First Hospital of Harbin were reviewed. Twelve pathology-proved rare and easily misdiagnosed cases were screened out for analysis of clinicopathological features and immunohistochemical markers retrospectively. Results: Twelve rare diseases of the stomach, including one case of primary squamous cell carcinoma, 8 cases of metastatic carcinoma, two cases of primary neuroendocrine tumor, and one case of cytomegalovirus (CMV) infection were enrolled. In 8 cases of metastatic carcinoma, 2 were mammary origin, 3 were kidney origin, 2 were lung origin and 1 was liver origin. Each lesion had its unique histomorphological appearance and specific immunohistochemical markers. Conclusions: Tissue obtained from gastroscopic biopsy is limited. Familiar with the histomorphology and immunohistochemical markers of rare diseases of the stomach may avoid misdiagnosis and inappropriate management.
