Objective To improve recognition of radiologic manifestations, mechanism, classification and differential diagnosis with the gastric benign tumor prolapsing into duodenal bulb. Methods We retrospectively analyzed and studied gastric bengin tumor prolapsing into duodenal bulb,data 8 cases performed GI series and gastroscopic examination in our hospital which all were proved by surgery and pathology. Results Radiologic manifestations of the gastric benign tumor prolapsing into duodenal bulb included①filllng defect in the duodenal bulb and in the duodenal descending segment;②pulling mucusal bridge sign and widened pyloric channal ;③revealed smooth of tumor surface mucosa and/or niche shadowes--″bull eyes″ sign;④changed of the entire gastric shape;⑤manifestation of tumor prolapsing vs retured into stomach ;⑥distribution of the primary gastric benign tumors:gastric antrum 6 cases, gastric body and fundus varied 1 case. Pathologic diagnosis the gastric benign tumors prolapsing into duodenal bulb, leiomyoma 4 cases,lipoma and neurolemmoma varied 1 case, prolapsing into duodenal decending segment, leiomyoma 2 cases. Conclusion Radiological diagnosing signs of the gastric benign tumor prolapsing into duodenal bulb include①filling defect in the duodenal bulb or duodenum ;②pulllng mucosal bridge sign ;③widened pyloric channel;④changed of the entire gastric shape.

BACKGROUND: With social development, the average life span is prolonged. The issue of aging has increasingly attracted people's attention. It is necessary to promote the health status and the guality of life of the elderly..OBJECTIVE: To understand the status and distribution features of several common diseases which influence the quality of life of elderly.DESIGN: Random cluster sampling methods and a cross-section survey.SETTING: Beijing Institute of Geriatrics of Beijing Hospital.PARTICIPANTS:Totally 1 558 old people aged ≥60 years living in 10 communities affiliated to Jianguomen district office of the Eastern District of Beijing City,and 8 villages affiliated to Xiangyang and Henan Villagers'Commissions of Shunyi County of Beijing from May 1997 and October 1997 were recruited.In fact,1 434 persons responded,with a response rate being 92％,319 males and 498 females came from the city;242 males and 375 females came from the villages.METHODS:Questionnaires were filled up,and physical examinations were conducted in all the elderly. MAIN OUTCOME MEASURES: The 6 common diseases were observed among the elderly: Hyperplasia of prostate, abnormal audition, cartaract ,osteoarthritis, fracture and constipation.RESULTS:Totally 1434 elderly entered the stage of result analysis.①The incidence of hyperplasia of prostate in the males from the urban areas was lower than that in the rural areas (61.4％,65.7％, P ＜ 0.01 ). ② The incidence of abnormal audition among the elderly from the urban areas was lower than that in the rural areas (53.9％,64.7％,P ＜ 0.01).③ The incidence of cataract of the two eyes in the elderly from the urban areas was higher than that in the rural areas(46.4％,44.4％, P ＜ 0.01). ④ The incidence of osteoarthropathy in the elderly from the urban areas was higher than that in the rural areas (24.4％,14.9, P ＜ 0.01). ⑤ The incidence of fracture in the elderly from the urban areas was higher than that in the rural areas (14.2％,9.1％, P ＜ 0.05). ⑥ The incidence of constipation of the elderly in urban areas was lower than that in the rural areas(18.2％,23.0％,P ＜ 0.05).CONCLUSION:There is a difference between the elderly from the urban areas and the rural areas in hyperplasis of prostate,abnormal audition, cataract, osteoarthropathy, fracture and constipation, and this is related with the economy, nutrition, medical conditions and cultural traits.Therefore, attention should be attached to nutrition and health knowledge of the elderly and prevention and treatment of common diseases among the elderly people.

Objective To study the effects of type 2 diabetes (T2DM) with hypertension on cognitive function in those community-based elderly who were aged 60 and over,in Beijing.Methods 82 patients with T2DM,142 patients with both T2DM and hypertension and 277 normal controls were investigated in this study.Both methods as:the Montreal Cognitive Assessment (MoCA) and Mini-Mental Status Examination (MMSE) were used to determine cognitive change.Results The total MMSE scores showed significant decrease between T2DM with hypertension and controls [(28.42± 1.52) vs.(28.88± 1.47),P＜0.05].The MoCA score of the total scores [(25.20± 3.91) vs.(26.50 ± 3.29),P＜0.05],sub-scores of visuospatial,executive [(3.60± 1.56) vs.(3.96± 1.18),P＜0.05] and language [(2.10± 0.80) vs.(2.37± 0.80),P＜0.05] significantly decreased in T2DM patients with hypertension and in the normal controls.Data from the Multiple logistic regression analysis showed that older age and less education were risk factors for cognitive impairment.Conclusion T2DM and hypertension damaged the cognitive function of patients.

Etiological research is necessary for understanding the occurrence and epidemiological patterns of diseases, and is also a prerequisite for the diagnosis, prevention and treatment of clinical diseases. Mendelian randomization(MR), a method of research that combines genetics and epidemiology, has the advantage of exploring the causal relationship between exposure and disease genetically as well as avoiding confounding factors and reverse causation. Thus, it has been extensively utilized in the etiological study of diseases. This paper reviews the implementation of MR in the research of ocular diseases and provides ideas and approaches for the investigation of related mechanisms as well as the development of intervention strategies.

Nasal preparations have unique advantages in drug delivery and are widely used in the treatment of local and systemic diseases. Nasal administration of traditional Chinese medicine （TCM） has a long history in China. In recent years， nasal preparations of TCM have attracted wide attention. Based on the information about nasal preparations of TCM from the database of National Medical Products Administration （NMPA）， Yaozh.com and China National Knowledge Internet （CNKI） in the recent 30 years， the formulation， the listed products， commonly used TCM， pharmaceutical excipients， clinical application and safety research of modern nasal preparations of TCM were summarized and expounded. Focusing on many problems in the development of modern nasal preparations of TCM， such as inaccurate dosage of some products， incomplete quality standard system of pharmaceutical excipients， imperfect safety evaluation， lack of research and development of nasal drug delivery devices and so on， the possible solutions and prospects were put forward from the aspects of optimizing the extraction and separation process of TCM， the quality control and application method of pharmaceutical excipients， the development of new dosage forms， the safety evaluation of nasal administration of TCM， and the design and development of nasal administration devices. The aim is to provide ideas for the development of nasal preparations of TCM and provide scientific basis for its sustainable utilization.
