Association between salted meat consumption and esophageal squamous cell carcinoma of population in high risk area of esophageal squamous cell carcinoma / 吉林大学学报(医学版)

Objective: To analyze the levels of dietary intake among the normal population, the esophagitis patients, and the esophageal squamous cell carcinoma (ESCO patients, and to elucidate the relationship between the diet and the incidence of ESCC. Methods : Frequency-matched case-control study was performed. The normal esophagus population (normal group), the esophagitis patients (esophagitis group) and the ESCC patients (ESCC group) (n=72) were enrolled. The general informations, intake conditions and relationship between the intake and ESCC of the subjects among three groups were compared. Unconditional Logistic regression model was used to estimate the OR and 95 %CI when salted meat consumption or not, frenquency of salted meat consumption and time of salted meat consumption in 1 year were brought into the analysis. Results: The family cancer history and family ESCC history in first-degree relatives of the subjects among three groups had significant differences (P

Efficient endoscopic screening in high-risk areas of esophageal cancer / 基础医学与临床

The incidence rate of esophageal cancer has been decreasing since 1988 in Linxian and Cixian as the results of year-round preventive effort for several decades.But remarkable decreasing in incidence is confined to age group above the age of 60 year old only.For the age group from 40 through 60,the decreasing is slight;and for those under the age of 40 years old,no decrease can be perceived.This suggests that the primary risk of esophageal cancer still remains as strong in the high-risk areas,and the decreased incidence may be credited mainly to secondary preventive measures.Although early diagnosis is still the key to control esophageal cancer presently,the rate of early detection is very low due to the lack of efficient screening programs in the high-risk areas.Recently,Cancer Foundation of China initiated a series of endoscopic screening programs across the country aimed to improve early detection and treatment in the field.The objective of this article is to provide clues to help improving screening efficiency in the field.

STUDIES ON CHARACTERISTICS OF SNAIL DISTRIBUTION IN CANAL AREA INSIDE EMBANKMENT AND FACTORS FORMING HIGH RISK AREA OF SCHISTOSOMIASIS / 中国血吸虫病防治杂志

Zishi township of Jiangling city is located in the canal area inside embankment,a heavy endemic area of schistosomiasis japonica in Hubei province. The population and cattle preva-lence was 29.5% and 66.7% respectively in 1992. There are 66 canals and it covered a total area of 300000m2. 97.0% of the canals and 99.3% of the total area had snail inhabitants, and 7.6% of the snails distributed in canal was infected which covered 18.3% of the total area. The snails were mainly distributed in the main canal and their branches. The rate of snail distribution was 45.2% and 39.8% respectively. Cattle was pastured all year round in this area. Examination of scattered cattle feces and water revealed that the major factor of water contamination was scattered cattle feces. It explained why the infection rate of snail was high and the distribution of infected snail was extensive and how the major high rise area inside embankment was formed.
