OBJECTIVETo find the major risk factors associated with gastric cardia cancer.

METHODSWe selected five high incidence areas of esophageal cancer and gastric cancer which have cancer registration system, i.e. Cixian and Shexian of Hebei Province, Linxian of Henan Province, Feicheng of Shandong Province and Zhuanghe of Liaoning Province. Fifty newly diagnosed cases of cardiac cancer after January 1, 2008 were selected from each cancer registration database. A uniform questionnaire, which was fully consulted by experts, was used. Population-based 1:3 case-control study was conducted in those areas. The study recruited 250 cases of cardiac cancer and 750 matched controls, which were investigated with the uniform questionnaire. The data were statistically analyzed by fitting-conditional Logistic analysis.

RESULTSSmoking, passive smoking, alcohol drinking, irregular meal, improper dining posture, heavy taste, dried food, pickled food, fried food, hot food, gastrointestinal history, gastroesophageal reflux disease (GERD) can increase the risk of cardiac cancer. To eat more bean and high BMI are protective factors of the single factor logistic analysis. Gastrointestinal history (OR = 42.899), dried food (OR = 5.932), irregular meal (OR = 4.911), hot food (OR = 4.144), pickled food (OR = 3.287), passive smoking (OR = 2.355), and GERD (OR = 1.930) can increase the risk of cardiac cancer, eat more bean (OR = 0.254) and BMI ≥ 25 (OR = 0.492) are protective factors of the mixture factors logistic analysis.

CONCLUSIONSGastric cardia cancer is caused by environmental risk factors and genetic factors. Health education in high cardiac cancer incidence areas and primary prevention popularized into people's daily life will be beneficial to decreasing the incidence of gastric cardia cancer.

OBJECTIVETo observe the distribution of the pre-cancerous condition and pathological changes of esophageal cancer of the community residents in high-incidence area, and to provide etiological evidences for secondary prevention.

METHODSAn iodine-staining endoscope census was conducted in 9536 residents with high-risk factors at Feicheng, a high esophageal cancer incidence community in Shandong province. Of which, 1507 pathologic biopsies were performed and chi2 test administrated.

RESULTSThere was no statistical significance found in biopsy pathologic diagnosis between females and males among 1507 samples. The mild and medium atypical hyperplasia was taken as pre-cancerous condition and severe atypical hyperplasia was taken as pre-cancerous lesion. Taking all the population attending census as denominator, the detection rate of the precancerous state and precancerous lesion were 6.98% (294/4214) and 1.23% (52/4214) for the males, and 3.68% (196/5322) and 0.47% (25/5322) for the females, respectively. A statistical significance was observed when comparing males with females (chi2 were 52.349 and 15.267, respectively, P < 0.05). Analyzed by age group, severe atypical hyperplasia pathological changes were mainly distributed in the age group of 50- and 65-. The constituent ratio between 45 - and 50 - was the highest for CIS. Early carcinoma was mainly distributed in five age groups from 45- to 65-. It showed that high incidence town had a high detection rate of cancer and pathological changes of esophageal cancer in the analysis of urban and rural distribution.

CONCLUSIONThe distribution of the pre-cancerous state and pathological changes of esophageal cancer of the residents should have provided a scientific basis for the primary and secondary prevention.

Objective:To investigate the correlation between right-to-left shunt (RLS) and infarct pattern in patients with cryptogenic stroke.Methods:Young and middle-aged patients with acute cryptogenic stroke admitted to the Department of Neurology, Xiaogan Central Hospital from May 2016 to January 2020 were enrolled retrospectively. The demographic data, vascular risk factors, baseline blood pressure, laboratory findings, stroke severity, infarct location and distribution pattern were documented. The patients were divided into RLS group and non-RLS group according to the findings of the transcranial Doppler ultrasound foaming test. They were divided into single lesion group and multiple-lesion group according to the findings of diffusion-weighted imaging. Multivariate logistic regression analysis was used to identify the correlation between RLS and infarct pattern. Results:A total of 68 patients with acute cryptogenic stroke were included, 37 of them were male (54.4%), and their age was 47.63±6.57 years (range, 31-59 years). Thirty patients (44.1%) had RLS, including 22 (73.3%) with mild shunt and 8 (26.7%) with severe shunt. The proportions of men, cortical-subcortical infarction and multiple blood supply area lesions in the RLS group were significantly higher than those in the non-RLS group, while triacylglycerol, body mass index, the proportions of patients with subcortical infarction and single lesions in the single vessel blood supply area were significantly lower than those in the non-RLS group ( P<0.05). The proportions of patients with anterior circulation+ posterior circulation infarction, cortical-subcortical infarction, and RLS in the multi-lesion group were significantly higher than those in the single-lesion group, while the proportion of patients with subcortical infarction was significantly lower than that in the single-lesion group (all P<0.05). Multivariate logistic regression analysis showed that RLS was an independent risk factor for multiple infarctions (odds ratio 6.681, 95% confidence interval 1.206-37.019; P=0.030). Conclusion:RLS is independently associated with multiple infarctions in patients with cryptogenic stroke.

Objective: To describe the status of non-steroidal anti-inflammatory drugs (NSAIDs) use in areas with a high incidence of upper gastrointestinal cancer in China. Methods: This study was based on the National Key Research and Development Program of "National Precision Medicine Cohort of Esophageal Cancer" and "Study on Identification and Prevention of High-risk Populations of Gastrointestinal Malignancies (Esophageal cancer, Gastric cancer and Colorectal cancer)" . From January 2017 to August 2018, 212 villages or communities with a high incidence of esophageal cancer or gastric cancer were selected from 12 regions in 6 provinces. A total of 35 910 residents aged between 40 and 69 years old who met the inclusion criteria and signed the informed consent were investigated and enrolled in this study. The use of NSAIDs, demographic characteristics, health-related habits, height, weight, and blood pressure were collected by the questionnaire and physical examination. The status of main NSAIDs (aspirin, acetaminophen and ibuprofen) use with the difference varying in genders, age groups and regions were analyzed by using χ² test and Cochran-Armitage trend analysis method. Results: Of 35 910 subjects, the mean age was (54.6±7.1) years old and males accounted for 43.42% (15 591). The overall prevalence of NSAIDs intake was 4.56% (1 638), but it significantly varied in different provinces (P<0.001). The overall prevalence of NSAIDs intake was 4.87% (1 750) in females, which was significantly higher than that in males 4.24% (1 524) (P<0.001). The prevalence of NSAIDs intake increased with age (P for trend <0.001). As the frequency of NSAIDs intake increased, the incidence of gastrointestinal symptoms, gastrointestinal ulcers and black stools increased (P for trend <0.05 for all). Conclusion The use of NSAIDs is prevalent in some areas with a high incidence of upper gastrointestinal cancer in China. The increased use of NSAIDs may lead to more adverse effects related to the gastrointestinal tract.
