RESUMO

Clonorchis sinensis, an important fish-borne zoonotic trematode, is widely distributed in South-East Asia, especially in China. Infections from human and animal reservoir hosts occur due to the consumption of raw or undercooked fish with C. sinensis metacercariae. This study aimed to evaluate the prevalence of C. sinensis metacercariae in fish in South-East Asia via systematic review and meta-analysis. We searched PubMed, ScienceDirect, China National Knowledge Infrastructure, Wanfang and Chongqing VIP databases for studies published between 1976 and 2020 that are related to the prevalence of C. sinensis metacercariae in fish. Studies were screened with keywords based on inclusion and exclusion criteria. Seventy-one eligible articles were identified, covering three countries: China, Korea and Vietnam. The pooled prevalence of C. sinensis metacercariae in fish from South-East Asia was 30.5%, with 35.1% in China, 29.7% in Korea and 8.4% in Vietnam. In subgroup analyses of climate, season, water source and publication date, the highest prevalence was identified in the Dwb climate type (43.3%), summer (70.2%), river (34.5%) and pre-2001 publications (38.9%), respectively. In comparison, the lowest prevalence was found in the Dfa climate type (14.5%), winter (19.5%), lake (8.0%) and post-2001 publications (23.8%). Meta-regression results indicated that country (p = .009), the published time (p = .035) and water source subgroups (p = .003) may be the source of heterogeneity. Overall, our study indicates that a high prevalence of C. sinensis infections occurs in fish in China, Korea and Vietnam, illuminating a significant public health concern in these countries.

RESUMO

Arrays of molybdenum(IV) disulfide nanosheets resembling the shape of golf balls (MoS2 NSBs) were deposited on carbon nanofibers (CNFs), which are shown to enable superior electrochemical detection of dopamine without any interference by uric acid. The MoS2 NSBs have a diameter of ∼ 2 µm and are made up of numerous bent nanosheets. MoS2 NSBs are connected by the CNFs through the center of the balls. Figures of merit for the resulting electrode include (a) a sensitivity of 6.24 µA·µM-1·cm-2, (b) a low working voltage (+0.17 V vs. Ag/AgCl), and (c) a low limit of detection (36 nM at S/N = 3). The electrode is selective over uric acid, reproducible and stable. It was applied to the determination of dopamine in spiked urine samples. The recoveries at levels of 10, 20 and 40 µM of DA are 101.6, 99.8 and 107.8%.

RESUMO

BACKGROUND: Gastroesophageal reflux disease (GERD) refers to a clinical condition characterized by gastric content reflux into the esophagus, causing symptoms like acid regurgitation and heartburn. While patient education is essential for GERD treatment, traditional educational models often struggle to effectively improve treatment outcomes. METHODS: Between January 2021 and April 2022, we enrolled 257 patients and assessed their GERD knowledge. The patients were randomly assigned to either the WeChat group (60 participants) for health education via WeChat platform or the control group (60 participants) for conventional education only. GERD-Q scores were collected at 1, 3, and 6 months post-intervention, with compliance and satisfaction assessed at the study's conclusion. RESULTS: The overall awareness rate of GERD among patients was approximately 22.3 %. The WeChat group showed better compliance than the control group in terms of adhering to a proper diet, taking medication on time, and engaging in moderate exercise (P < 0.05 for all). Furthermore, the WeChat group demonstrated significantly higher treatment effectiveness and satisfaction than the control group (P < 0.05 for all). CONCLUSION: Patients have a relatively low level of knowledge regarding GERD. WeChat has the potential to facilitate lifestyle changes and improve compliance, treatment effectiveness, and treatment satisfaction among patients with gastroesophageal reflux disease.

RESUMO

Excessive oxidative stress and NLRP3 inflammasome activation are considered the main drivers of inflammatory bowel disease (IBD), and inhibition of inflammasomes ameliorates clinical symptoms and morphological manifestations of IBD. Herein, we examined the roles of NLRP3 activation in IBD and modulation of NLRP3 by sulforaphane (SFN), a compound with multiple pharmacological activities that is extracted from cruciferous plants. To simulate human IBD, we established a mouse colitis model by administering dextran sodium sulfate in the drinking water. SFN (25, 50 mg·kg-1·d-1, ig) or the positive control sulfasalazine (500 mg/kg, ig) was administered to colitis-affected mice for 7 days. Model mice displayed pathological alterations in colon tissue as well as classic symptoms of colitis beyond substantial tissue inflammation. Expression of NLRP3, ASC, and caspase-1 was significantly elevated in the colonic epithelium. The expression of NLRP3 inflammasomes led to activation of downstream proteins and increases in the cytokines IL-18 and IL-1ß. SFN administration either fully or partially reversed these changes, thus restoring IL-18 and IL-1ß, substantially inhibiting NLRP3 activation, and decreasing inflammation. SFN alleviated the inflammation induced by LPS and NLRP3 agonists in RAW264.7 cells by decreasing the levels of reactive oxygen species. In summary, our results revealed the pathological roles of oxidative stress and NLRP3 in colitis, and indicated that SFN might serve as a natural NLRP3 inhibitor, thereby providing a new strategy for alternative colitis treatment.
