        • Clinical Epidemiological Characteristics of Gastric Cancer in Recent 10 Years

          Objective To explore the clinical epidemiologic characteristics and tendency of gastric cancer during recently ten years in northern Henan province. Methods The clinical data of 1 090 patients with gastric cancer in our department were collected from January 1998 to May 2008. The ten-year period was divided into two groups: previous 5 years group (n=433) and post 5 years group (n=657). The age, gender, pathologic characteristics and the relationship between age and pathologic features were analyzed retrospectively. Results ①The patient’s age was 15-83 years old 〔mean (57.60±10.84) years old〕 and men-momen ratio was 3.71∶1 in previous 5-year group. The patient’s age was 18-82 years old 〔mean (58.95±10.81)years old〕 and men-momen ratio was 2.84∶1 in post 5-year group. There was no significant difference in age or gender between two groups (Pgt;0.05). ②Gastric cancer arised in cardia and gastric fundus more common and for the incidence of the site no change was found in two groups. The incidence of gastric antrum cancer descended but that of gastric body arised. ③The mean age of patients with gastrocardiac cancer was significantly different (Plt;0.05) between two groups. No significant difference occurred on the mean age of patients with gastric antrum (Pgt;0.05) or gastric body cancer (Pgt;0.05). The mean age of patients with highly malignant tumor (signet ring cell cancer, poorly differentiated adenocarcinoma and undifferentiated carcinoma) was significantly different compared with that of patients with lowly malignant tumor (well differentiated and moderately differentiated adenocarcinoma) (Plt;0.05). ④The proportion of patients with highly and lowly malignant tumor presented significantly different between the previous 5 years and the post 5 years (Plt;0.05). ⑤The proportion of early gastric cancer was very low and no correlation was found between infiltrating depth and age in all patients (Pgt;0.05). Conclusion Cardia and gastric fundus is the most common site of gastric cancer in northern Henan province. The patients with gastrocardiac cancer are often older but gastric antrum and gastric body cancer patients are younger. Highly malignant gastric cancer is often found in youths, however, lowly malignant gastric cancer occurred predominantly in elderly. The proportion of gastric cancer found early is very low in northern Henan province.

        • Epidemiological investigation of ocular fundus diseases in Tibetan above 40 in Maqin county, Qinghai Province

          Objective To investigate the morbidity of ocular fundus diseases in Tibetan above 40 in Maqin county, Qinghai Province. Methods A total of 2511 Tibetan above 40 in Maqin county, Qinghai Province were seelected by cluster sampling method. The sampling survey of ocular fundus diseases was performed on the individuals with indirect ophthalmoscope, and the results were compared with the domestic existing epidemiological data. Results Two hundred and thirty five (9.35%) cases were found to have abnormal ocular fundus, and the blindness rate due to the abnormal ocular fundus was 20.5% (80/391 eyes) which was lower than the blindness rate due to cataract (52.5%). Low vision and blindness led by ocular fundus diseases were found in 155 eyes (65.96%),including 74(47.74%) with age-related macular degeneration (AMD) and 23 (9.79%) with retinoangiopathy. Conclusions The morbidity of ocular fundus disorder is higher in high plateau than that in backland; AMD and retinoangiopathy are the main diseases leading to blindness.

        • Clinical analysis of 282 patients with infectious endophthalmitis

          Objective To analyze the causes and pathogens of infectious endophthalmitis in our hospital. Methods The clinical data and laboratory findings of 282 inpatients with infectious endophthalmitis were retrospectively reviewed. There were 206 males(73.05%)and 76 females(26.95%)with a mean age of (36.0plusmn;11.2) years (range from 2 to 79 years). Except 14 patients who lost their eyeballs as of serious conditions, pathogen examinations of vitreous specimen had been performed for all remaining 268 cases. The clinical and laboratory data were statistically analyzed by Chi-square and Kappa consistency tests, when P<0.05 the difference should be considered as statistically significant. Results The 4 major causes of infectious endophthalmitis of those 282 patients included ocular trauma (177 cases, 62.77%), infectious keratitis (61 cases, 21.63%), eye surgery (32 cases, 11.35%), and endogenous endophthalmitis (12 cases, 4.25%). 19.21% of the patients in ocular trauma group was 2-13 years old, 55.74% of the patients in infectious keratitis group was 14 -50 years old, and 60.61% of the patients in eye surgery group was 51-79 years old. The major pathogens were fungus and staphylococci each accounted for 30.63% of all cases. Most of the pathogenic bacteria were sensitive to ciprofloxacin (81.81%) and gentamicin (77.92%). Conclusions The major reason of infectious endophthalmitis was ocular trauma, and the major pathogens were fungus and staphylococci. Those findings may help us to treat infectious endophthalmitis patients appropriately.

          Objective To analyze the clinical epidemiological characteristics and trends of newly reported human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients in Panzhihua Central Hospital, and provide a scientific basis for general hospitals to formulate precise prevention and control measures. Methods The information such as gender, age, ethnicity, and transmission route of the newly reported HIV/AIDS patients in Panzhihua Central Hospital from 2010 to 2019 was retrospectively analyzed. Results A total of 551545 patients were screened for HIV in Panzhihua Central Hospital between 2010 and 2019, among them, 1091 patients were confirmed as HIV infection finally, with a confirmed positive rate of 0.20%. The number of confirmed cases and the positive rate continued to increase from 2010 to 2017, and obviously declined after 2018. The male to female ratio of newly diagnosed HIV/AIDS patients was 2.86∶1, and the 31-45 years old middle-aged and young adults were the majority (31.16%). The majority of HIV/AIDS patients were identified as married (58.02%), primary school education (40.70%), farmers (46.38%), and Han nationality (79.84%). Yi nationality also had a high proportion (18.52%) with an increasing trend year by year (χ2trend=8.131, P=0.004). Yi nationality patients were mainly from Liangshan Yi Autonomous Prefecture (58.42%). A high proportion of 50.32% of patients came from other cities, among them, the proportion of patients from Liangshan Yi Autonomous Prefecture increased over time (χ2trend=13.608, P<0.001). The transmission routes were mainly through heterosexual sex (90.93%), with an upward tendency of proportion (χ2trend=22.137, P<0.001), and transmission through drug abuse was following (4.49%), with an downward tendency of the proportion (χ2trend=11.758, P=0.001). Significant differences in transmission routes were observed between males and females (P=0.020), and between Han nationality and Yi nationality (P<0.001).
