Objective The aim of this study was to explore the effect of minimally invasive small incision surgery on early thoracic esophageal cancer patients and its impact on pain. Methods A total of 160 patients with early thoracic esophageal cancer who were treated in our hospital from March 2016 to March 2017 were randomly divided into the conventional surgery group and the minimally invasive small incision surgery group. Patients in the conventional surgery group were treated with routine operation,and pa-tients in the minimally invasive small incision surgery group were treated with minimally invasive small incision surgery. Vital capacity ( VC),forced expiratory volume 1(FEV1),visual analogue scale(VAS),hospitalization time,operation time and intraoperative bleed-ing volume were counted. Growth hormone(GH)was detected by ELISA. The levels of cortisol(Cor) and interleukin-8( IL-8) were measured by immunoassay and adverse reactions. Results The levels of VC and FEV1 in the minimally invasive small incision group were significantly higher than those in the conventional surgery group. The bleeding volume,operation time and hospitalization time were shorter than those in the conventional surgery group. The levels of GH and Cor,VAS score and incidence of adverse reaction rate were lower than those in the conventional surgery group,and the level of IL-8 was also higher in than that in the conventional surgery group. The difference was statistically significant(P<0. 05). Conclusion Minimally invasive small incision surgery is effective on the treatment of early thoracic esophageal cancer,relieving pain and reducing adverse reactions.

Objective:To analyze the epidemiological and clinical characteristics of human brucellosis in Sichuan Province, and to provide a scientific basis for prevention and control of brucellosis.Methods:Retrospective analysis methods were used to collect the data of reported cases of brucellosis in Sichuan Province from 2018 to 2020 from the "Infectious Disease Reporting Information Management System" in the "China Disease Prevention and Control Information System". The distribution (population, time and region) and case investigation data (epidemiological contact history and clinical manifestations) were analyzed by descriptive epidemiological.Results:A total of 309 cases of brucellosis were reported in Sichuan Province in 2018 - 2020, and no deaths occurred. The annual incidence rate was 0.123/100 000. Among the 309 reported cases of brucellosis, the sex ratio of men to women was 2.4 ∶ 1.0 (218 ∶ 91); the age of onset was mainly 20 - 60 years old, accounting for 79.9% (247/309); the occupation was mainly farmers, accounting for 51.8% (160/309). Brucellosis cases were reported in every month of the year, mainly from March to August, accounting for 72.5% (224/309) of the total number of cases. Cases were reported in 21 cities (autonomous prefectures) in Sichuan Province from 2018 to 2020. The top 5 cities (autonomous prefectures) in terms of cumulative number of cases were Chengdu, Liangshan, Zigong, Neijiang and Luzhou in order, accounting for 60.5% (187/309) of the total number of cases. Among the 309 reported cases of brucellosis, 279 case investigations were completed. Among them, 258 cases had a history of contact with livestock and their products, accounting for 92.5%; all contacted livestock were sheep; the main mode of transmission was direct contact, accounting for 88.5% (247/279); the main routes of transmission were sheep farming (50.2%, 140/279), sheep slaughtering (18.6%, 52/279), selling mutton or cutting sheep products in mutton restaurants (11.1%, 31/279); the main clinical manifestations were fever, fatigue, hyperhidrosis, and muscle and joint pain, accounting for 91.4% (255/279), 89.2% (249/279), 80.3% (224/279) and 65.2% (182/279), respectively.Conclusions:The spread of brucellosis in Sichuan Province is increasing, and spring and summer are the epidemic seasons. Brucellosis cases are most common in sheep farms, and the infection method is mainly direct contact infection; the clinical manifestations are diverse and non-specific. Relevant departments should strengthen the prevention and control of the disease in key populations and regions to control the outbreak of brucellosis.
