ObjectiveTo summary the study results of the Sichuan Gastric Cancer Early Detection and Screening Research Program (SIGES). MethodsIn the past 10 years, SIGES program conducted a series of clinical and clinical epidemiological studies on the current situation and strategies of gastric cancer prevention and control in China, which provided evidence for supply-side structural reform to improve the gastric cancer prevention and control. We collected related studies and made a review. ResultsSIGES program systematically and specifically studied carcinogenic pathogens, risk factors, screening strategies, as well as critical technique and system construction of tertiary prevention for gastric cancer. The main results supported that Helicobacter pylori was highly correlated with precancerous atrophic gastritis and gastric cancer. Oncoviruses, such as Epstein-Barr virus, hepatitis B virus, human cytomegalovirus, human papillomavirus, John Cunningham virus were correlated with the risk of gastric cancer, and should be paid further attention in the prevention and screening strategy of gastric cancer. Ethnicity, domicile, and family history of gastric cancer were also correlated with gastric cancer and gastric cancer-related risk factors, so it was suggested to include in the personalized evaluation criteria system of high-risk groups for gastric cancer. ConclusionsAt present, the prevention and control of gastric cancer in China has achieved substantial achievements, but the burden of gastric cancer keeps heavy. It is still necessary to conduct further scientific research on critical technique or issues in designing prevention and control strategies.

ObjectiveIn order to provide guidance for early interference of diabetic retinopathy (DR) in patients with diabetes mellitus (DM), we surveyed the prevalence and analysis the related factors of DR in Shanghai Songnan community.
MethodsBased on an established resident health database, an epidemiology study was performed on the residents with DM in Shanghai Songnan community.1177 patients completed questionnaire survey, and received physical examination and laboratory tests. The diagnosis and grading of DR were established based on the ocular fundus images acquired by digital non-mydriasis fundus camera. Patients with incomplete questionnaires were excluded.
ResultsThere were 1120 DM patients with valid questionnaires. DR was found in 264 (23.57%) patients. The prevalence of mild, moderate, severe non-proliferative DR and proliferative DR was 17.05%, 5.09%, 1.16% and 0.27% respectively. There was significant differences in age, disease course, systolic blood pressure, insulin usage between the DR group and NDR group(t=-2.647, 2.688, 2.204, 2.291;χ2=12.527;P=0.008, 0.007, 0.028, 0.022, 0.000). There was significant differences in fasting blood-glucose and insulin usage between the mild, the moderate and the severe DR group(t=21.964, χ2=14.996;P=0.000, 0.001). Stepwise logistic analysis identified that age, DM course, and insulin usage were the related factors of DR (OR=0.769, 1.239, 1.100, 1.071, 1.682;P=0.001, 0.043, 0.176, 0.097, 0.005).
ConclusionThe age, DM course, and insulin usage were the related factors of DR. The high prevalence of DR indicated the importance of the management of diabetic patients.
Objective To review the research progress on the correlation between sarcopenia and osteoarthritis (OA). Methods The basic and clinical studies at home and abroad in recent years on sarcopenia and OA were extensively reviewed. The correlation between sarcopenia and OA was analyzed and summarized from five aspects: epidemiological status, risk factors, pathogenesis, clinical treatments, and the impact on joint arthroplasty. Results Sarcopenia and OA are common diseases in the elderly with high prevalence and can increase the ill risk of each other. They share a set of risk factors, and show negative interactive and influence on pathogenesis and clinical treatments, thus participating in each other’s disease process and reducing the treatment benefits. Clinical studies show that sarcopenia can affect the rehabilitation effect and increase the risk of postoperative complications after total joint arthroplasty in many ways. ConclusionCurrent research results show that sarcopenia and OA are related and can be mutually affected in the above 5 aspects, but more studies are needed to further clarify the relationship between them, so as to provide more theoretical basis for the understanding, prevention, diagnosis, and treatments of the two diseases.
Purpose
To decribe the prevalence of age related macular degeneration (AMD) in the population aged 50 and over in Doumen County of Gunagdong Province. Methods
After randomized clustering sampling,all selected individuals were enumerated according to village residence register.Visual acuity were measured by illuminated EDTRS chart. The examination of eyelid,cornea,lens and fundus were also carried out.The diagnosis of AMD was made according to the criteria of National Academic Group of Fundus Diseases combining with the visual criteria of Framingham Eye Study. Results
5 324 indivduals were axamined with participating rate of 92.8%.The ove rall prevalence of AMD was 8.4%.The prevalence of 2.9%,7.8% and 12.9% was found in the age groups of 50-,60-,70- respectively.The prevalence of male and female was 8.5% and 8.4% respctively.5% of AMD eyes were blind and 49% were low vision. Conclusion
The prevalence of AMD is hight and increased with aging,but not correlated with sex.AMD can cause severe visual impairment. (Chin J Ocul Fundus Dis,1998,14:122-124)
Purpose
Researching the relared risk factors of diabetic retinopathy (DR) through the epidemiological investigation.
Methods
Basing on a population random sampling survey and screening in 6 areas and cities of Anhui,216 diabetics were screened and they were then investigated in detail by filling in forms,measuring blood pressure,ocular examination including ophthalmoscopy,and lab examination including fasting blood glucose (FBG),blood glucose 2 hours after meal,urine albumin excretion (UAE),serum triglyceride,and cholesterol.
Results
The resultant date revealed that the duration of diabetes,blood pressure FBG and UAE were associated significantly with DR (Plt;0.05),and serum triglyceride and cholesterol were associated not significantly with DR(Pgt;0.05).
Conclusion
Long duration of diabetes,hight FBG and hight blood pressure are the important risk factors of DR,and urine albumin might forebode the occurrence of DR.

Mitral regurgitation (MR) is the most common heart valve disease. In recent years, the rise of interventional therapy has expanded the indications of interventional treatment for patients with MR, but the epidemiological characteristics of MR (especially the number of patients with MR requiring treatment) in China are still unclear. In this paper, we analyzed and estimated the number of MR patients in China based on three epidemiological studies in Europe and America, and referring to the patients population surveys from Zhongshan Hospital Affiliated to Fudan University, the Second Affiliated Hospital Zhejiang University School of Medicine and Beijing Fuwai Hospital. Our analysis estimated that about 7.5 million patients with MR need intervention in China, including about 5.5 million patients with severe MR.
Objective
To observe the clinical manifestation and treatment effect of Coatsprime; disease in adulthood.
Methods
The clinical data of 18 adult patients with Coatsprime; disease from 1980 to 2006 at the department of ophthalmology, Peking Union Medical College Hospital which had been diagnosed by ocular fundus examination and fundus fluorescein angiography (FFA), were retrospectively analyzed. The follow-up period was one year. Coatsprime; response diseases in all the patiens were excluded, such as history of radiation therapy, intraocular inflammation, retinal vascular occlusion, age-related macular degeneration (AMD) and more leakage of diabetic retinopathy. The patients, 14 males and 4 females, 11 left eyes and 7 right eyes, all of them occurs in unilateral; aged from 37 to 55 years with the average age of 43 years; the initial diagnostic vision was 0.02 to 1.5, the visual value was 0.1. 17 patients (17 eyes) were treated by laser photocoagulation, 1 patient was treated by release of retinal operation with condensation. The mean follow up period was 3.7 years (ranged from 1 to 15.3 years).
Results
In 18 patients (18 eyes), vitreous clear in 14 eyes, vitreous few muddy in 4 years when initial diagnosis. The optic discs in 18 eyes are normal. Lesions confined to one or two quadrant, for the most are in the temporal(15/18 eyes), less are in Bice (4/18 eyes), only one eye at top; two eyes lesions involved in 2 quadrant. There are typical retinal vascular anomalies expansion, miliary aneurysm, arterial aneurysm, macroaneurysms and capillary without perfusion areas; yellowwhite hard leakage by a large block or cluster in Lesion corresponding region. More than half of the eyes with macular edema or leakage; limited retinal detachment in 4 eyes, the range was very wide in 1 eye; retinal hemorrhage in 3 eyes. After treatment the exudation or the hemorrhage were absorbed and retinas were reset. Compared the visual acuity with before treatment, mostly (64.3%) improved 2 lines or keep in 1.2-1.5, no one decreased over 2 lines. The last vision was 0.02-1.5, the visual value was 0.1. Conclusions
Coatsprime; disease in adulthood diagnosed in first time has similar characteristics with children, such as vascular anomaly of retina, fundus exudation. The differences including limited area of involvement, less hemorrhages, mild damage on macular, slow development of lesions in follow-up period and better visual prognosis.

Objective To analyze the clinical information of COVID-19 patients of Shanghai National Exhibition and Convention Center cabin hospital, and to explore the medical management strategy to provide thoughtful suggestions for other cabin hospitals and governments as valuable references. Methods The clinical data of 174 308 patients confirmed COVID-19 in Shanghai National Exhibition and Convention Center cabin hospital from April 9 to May 31, 2022 were retrospectively reviewed. There were 103 539 male and 70 769 female patients, with an average age of 41.50±15.30 years. Medical and nursing management strategy was summarized. Results Among the 174 308 patients, 71.5% (124 630 patients) were asymptomatic. The vaccination rate of patients with COVID-19 in the cabin hospital was 76.5% (133 338 patients), and the majority of none vaccinated patients were children under the age of 10 years and the elderly over the age of 60 years, the vaccination rate of whom was only 25.0% (1 322 patients) and 63.9% (13 715 patients), respectively. In addition, the proportion of mild symptom type in the patients not vaccinated was significantly higher than that in the vaccinated patients (P≤0.01). The average hospitalization time of patients in cabin hospital was 7.39±0.53 days, which was 7.01±2.12 days for patients under 60 years and 8.21±0.82 days for patients over 60 years. The hospitalization time of elderly patients was significantly longer (P≤0.01), and the hospitalization time of elderly patients at age over 60 years without vaccination was 8.94±1.71 days, which was significantly longer than the average hospitalization time and the time of elderly patients vaccinated (P≤0.01). The number of patients combined with basic diseases was 27 864 (16.0%), of which cardiovascular diseases accounted for 81.3% (22 653 patients). A total of 2 085 patients were transferred and treated in designated hospitals. Conclusion Large scale cabin hospitals are helpful to cut off the source of infection. Attention shall be paid to the sorting of admission and timely transfer to other hospital during the patients management. Most of the patients have a good prognosis after treatment. The vaccination of key population and community-based screening will be the next step of focus.
