Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

Gut microbiota is a complex and dynamic system, and is essential for the health of the body. As the "second genome" of the body, it can establish communication with the important organs by regulating intestinal nerves, gastrointestinal hormones, intestinal barrier, immunity and metabolism, thus affecting host′s physiological functions. Short chain fatty acid (SCFA), known as one important metabolite of intestinal microbiota, is regarded as a significant messenger of the gut-organ communication, due to its extensive regulation in the body′s immunity, metabolism, endocrine and signal transduction. In this review, we summarize the interaction between gut-liver/brain/kidney/lung axis and diseases, and focus on the role and mechanism of SCFA in the gut-organ communication, hoping to provide new ideas for the treatment of the related diseases.

Objective:To investigate characteristics of the 18F-flurodeoxyglucose ( 18F-FDG) uptake intensity and ranges in distinct hepatic alveolar echinococcosis lesions. Methods:The clinical data of 39 patients with position emission tomography during Jan 2017 to Dec 2019 in the First Affiliated Hospital of Xinjiang Medical University were enrolled. Among them, there were 17 males and 22 females, aging from 15 to 65 years (median 34 years). Lesions were classified into six groups based on heterogenic scales of calcification and liquefaction: A. non-calcified and non-liquefied ( n=7); B. obvious calcified and non-liquefied ( n=7); C. partial calcified and partial liquefied( n=10); D. obvious calcified and partial liquefied ( n=5); E. partial calcified and subtotal liquefied ( n=5); F. obvious calcified and subtotal liquefied ( n=5). Tumor to background ratio (TBR) and width (W) of lesion infiltrative boundary were measured and calculated. Statistical comparison using Mann-Whitney U test as well as correlation analysis was performed. Results:TBR values [ M( Q1, Q3)] for each group were 4.40(3.66, 7.03), 2.55(1.69, 3.60), 3.73(3.37, 5.21), 2.90(2.75, 3.60), 3.80(3.49, 6.36), 2.49(2.21, 3.97), among which A>B, A>D, A>F, C>B, E>B ( U=3.0, 4.0, 4.5, 11.0, 5.0, all P<0.05); From the perspective of the calcification in each group, it was found that the lighter the calcification was, the greater the TBR value was. W values [ M( Q1, Q3)] for each group were [12.5(10.0, 19.5), 11.2(10.5, 12.5), 12.2(10.9, 13.2), 7.8(7.3, 9.3), 10.0(7.3, 13.4), 7.3(6.8, 7.6)] mm, among which A>D, A>F, B>D, B>F, C>D, C>F (all U=0, all P<0.05); According to the degree of calcification and liquefaction of lesions in each group, the lighter the calcification was, the greater the W value was; The heavier the liquefaction was, the smaller the W value was. A mild strength linear correlation has been observed between the TBR value and W value ( r=0.4136, P<0.05). Conclusions:Less calcification and liquefaction implicated higher 18F-FDG uptake intensity and wider range. Radical resection margins and tissue sampling should be individualized based on different lesion features in surgical treatment.
