Objective To assess the schistosomiasis transmission risk after flood disaster in Hubei Province in 2021, so as to provide a scientific basis for schistosomiasis prevention and control in corresponding areas. Methods The data pertaining to the endemic situation of schistosomiasis were collected from Hubei, including oncomelania snail distribution, and humans and livestock schistosomiasis infection. The warning water level and actual water situation were collected in corresponding water areas. The cumulative numbers of S. japonicum egg-positive people and cattle from 2014 to 2020, the distribution area of oncomelania snail in 2020, and the water levels from May 1 to August 31, 2021, were estimated and employed as parameters for classification of schistosomiasis transmission risk. The cumulative value of each risk index was calculated in each epidemic county (city and district) to comprehensively assess the risk of schistosomiasis transmission after flood disaster in each region. Results After the flood disaster in Hubei province in 2021, there were 2 counties (districts) at high risk of schistosomiasis transmission in Hubei based on the single risk index of fecal positive number. Based on comprehensive risk indices, there were 2 counties identified at grade 4 risk of schistosomiasis transmission. Conclusion After the flood in 2021, schistosomiasis in Hubei Province is mainly at low and medium epidemic risk. Xiantao City and Hanchuan City in Hanjiang River Basin are the two most seriously affected schistosomiasis epidemic cities. Flood disasters can increase the risk of schistosomiasis transmission and epidemic, so the monitoring and control of schistosomiasis after flood should be strengthened to control the disease transmission to the maximum extent.

Psoriasis vulgaris is a recurrent inflammatory skin disease. A variety of factors, such as trauma and infection, can destroy the skin barrier function, thereby breaking the balance of immune homeostasis and tolerance, causing abnormalities in function and/or number of various immune-related cells in local skin, resulting in psoriasis-like skin changes such as abnormal proliferation of keratinocytes and excessive inflammatory reactions in skin lesions. Various immune cells in skin lesions can sense changes in the surrounding environment (autocrine or paracrine) through surface molecules, and then express and secrete a variety of inflammation-related factors; if maintenance mechanisms for immune homeostasis and tolerance become invalid, the positive feedback network of inflammation mediated by inflammation-related factors will be formed locally, leading to the occurrence of psoriasis vulgaris. This review summarizes research progress in the role of immune-related cells in skin lesions in the immunopathological mechanism of psoriasis vulgaris, especially innate immune cells such as γδT cells.

MicroRNAs (miRNAs) are a class of non-coding RNA molecules that regulate gene expression after transcription and participate in various pathophysiological processes in the skin. In recent years, it has been reported that changes in miRNA expression profiles are related to some inflammatory skin diseases. For example, miR-203, miR-146a and miR-21 are upregulated in psoriatic lesions, miR-155 and miR-146a are upregulated in atopic dermatitis lesions, miR-21, miR-223, miR-142-3p and miR142-5p are upregulated in allergic contact dermatitis lesions; however, miR-146a and miR-155 are downregulated in peripheral blood of patients with systemic lupus erythematosus, and miR-223 is downregulated in dermatomyositis lesions. This review summarizes relationships of miRNAs with the occurrence and development of some inflammatory skin diseases.

In recent years, the category of atopic dermatitis (AD) has been updated in domestic and foreign guidelines, and elderly AD has been added as a subtype. The pathogenesis of elderly AD is related to heredity, skin barrier dysfunction, immune dysregulation and lifestyle. Most elderly AD patients have atypical clinical symptoms, and misdiagnosis is very common. To fully understand the pathogenesis and clinical characteristics of elderly AD, and to formulate individualized diagnosis and treatment plans based on clinical characteristics, are particularly important for improving the quality of life of patients and reducing the burden of the disease.

Objective To study the trends of lung cancer mortality among adult residents in Macheng City, Hubei Province from 1984 to 2018． Methods Mortality data was extracted from Macheng City disease surveillance points (DSPs) system and China Demographic Yearbook. The age-period-cohort (APC) model and Intrinsic Estimator algorithm were used to estimate the age effect, period effect and cohort effect of lung cancer mortality. Results The age effect coefficient of lung cancer mortality increased with age from 20 to 74 years old. The mortality risk of the 70-74 group was 42.62 times that of the 20-24 group. The period effect coefficient of lung cancer mortality also continued to rise with time. The cohort effect coefficient was parabolic, and residents born in 1939-1943 had the highest coefficient (1.298 4). Conclusion The risk of lung cancer death of adult residents in Macheng City significantly increased with the year and the rapid development of socio-economics.

Objective: To identify differentially expressed genes in the transcriptome of the lesional versus nonlesional skin tissues of patients with moderate and severe atopic dermatitis (AD) , and to elucidate their roles in the pathogenesis of AD. Methods: From July to October in 2016, lesional and nonlesional skin tissues were obtained from 5 outpatients of Han nationality with AD in Guangzhou Institute of Dermatology, Institute of Dermatology, Guangzhou Medical University. The next-generation high-throughput transcriptome-wide RNA sequencing (RNA-seq) was performed to identify differentially expressed genes, which were subjected to GO function annotation and KEGG pathway analysis. Real-time fluorescence-based quantitative PCR (qRT-PCR) was conducted to verify differences in candidate gene expression between lesional and nonlesional skin tissues. Results: An average of 10.96 GBs sequence reads were acquired among 10 samples. A total of 21 729 genes were detected, including 19 268 known genes and 2 545 predicted novel genes. A total of 23 153 new transcripts were detected, of which 18 889 were new alternative splicing subtypes of known protein-coding genes, 2 545 were transcripts belonging to new protein-coding genes, and the remaining 1 719 belonged to long-stranded non-coding RNA. Totally, 78 differentially expressed genes were identified between the lesional and nonlesional skin tissues, including 69 upregulated and 11 downregulated genes in the lesional skin tissues. Among them, there were several genes known to be associated with AD inflammation (CXCL1/2/8, IL6/IL1β, MMP1, SERPINB4, S100A2, GZMB, OASL, OSM) and barrier (KRT16, FABP5, CYP1A1) and keratinocyte differentiation (IL-20) . GO analysis revealed that functions of 72 differentially expressed genes could be annotated. KEGG pathway analysis showed that the differentially expressed genes were grouped into 132 signaling pathways, of which 13 were significantly enriched, including the interleukin (IL) -17 pathway, NOD-like receptor signaling pathway, Toll-like receptor signaling pathway, etc. qRT-PCR showed that the mRNA expression levels of candidate genes CXCL1, KRT6A, IL36A, SERPINB4 and PSAPL1 was consistent with the transcriptome sequencing results. Conclusions Differentially expressed genes and related important regulatory signaling pathways were identified between the lesional and nonlesional skin tissues of patients with AD at the transcriptional level, and the IL-17 pathway was found to be mostly enriched in AD lesions in patients of Han nationality. These findings provide an important basis for further study on the pathogenesis of AD..
