Background Occupational disease diagnosis appraisal is an appeal procedure initiated when a party disagrees with the occupational disease diagnosis conclusion. It is a legal procedure to safeguard the health rights of employees and the legitimate rights and interests of employers. Objective To analyze the data of occupational disease diagnosis appraisal in Shanghai, identify existing problems, and provide suggestions for improving. Methods Statistical analysis was conducted on basic situation, characteristics of workers and employers, disease classification, and consistency between diagnosis and appraisal conclusions of all occupational disease diagnosis appraisal cases from 2012 to 2024. All diagnosis conclusions were named in accordance with the Classified Catalogue of Occupational Diseases included employers were classified according to the Measures for the Statistical Classification of Large, Medium, Small and Micro Enterprises" and the Notice on Adjusting the Provisions for Classifying Enterprise Registration Types; industry classification followed the Industrial Classification for National Economic Activities (GB/T 4754-2017). Results From 2012 to 2024, a total of 260 cases of occupational diseases diagnosis appraisal were closed. The main diagnosis were 138 cases of ear, nose, throat, and oral diseases (53.1%), chemical poisoning (18.8%), and pneumoconiosis and other respiratory diseases (16.2%). The proportion of ear, nose, throat, and oral diseases gradually increased (2022 excluded). The incidence of annual municipal and provincial cases decreased by 76.3% and 85.0% respectively (2024 vs 2012). The consistency rate of conclusions between appraisal and diagnosis gradually increased. The total consistency rates between final appraisals and diagnostic conclusions were 81.5%, and 79.7%, 87.8%, 100.0%, 85.0% for ear, nose, throat, and oral diseases, chemical poisoning, and pneumoconiosis and other respiratory system diseases, respectively. Specifically, the consistency rates were 80.1% and 80.0% for noise-induced deafness and chronic benzene poisoning. In terms of inconsistency reasons, "inconsistent interpretation of standards and excessive discretion in standard application" accounted for 43.8%, followed by "failure to correctly apply standards" (31.3%) and and "discrepancies in occupational exposure history recognition" (15.6%). Conclusion The revisions and improvements of the legal system for occupational disease diagnosis appraisal have played a positive role in improving the consistency of conclusions between appraisal and diagnosis of occupational diseases in Shanghai. It is suggested to further strengthening the publicity and training of occupational disease diagnosis standards to improve the quality of occupational disease diagnosis.

Peptides are a particular molecule class with inherent attributes of some small-molecule drugs and macromolecular biologics, thereby inspiring continuous searches for peptides with therapeutic and/or agrochemical potentials. However, the success rate is decreasing, presumably because many interesting but less-abundant peptides are so scarce or labile that they are likely 'overlooked' during the characterization effort. Here, we present the biochemical characterization and druggability improvement of an unprecedented minor fungal RiPP (ribosomally synthesized and post-translationally modified peptide), named acalitide, by taking the relevant advantages of metabolomics approach and disulfide-bridged substructure which is more frequently imprinted in the marketed peptide drug molecules. Acalitide is biosynthetically unique in the macrotricyclization via two disulfide bridges and a protease (AcaB)-catalyzed lactamization of AcaA, an unprecedented precursor peptide. Such a biosynthetic logic was successfully re-edited for its sample supply renewal to facilitate the identification of the in vitro and in vivo antiparkinsonian efficacy of acalitide which was further confirmed safe and rendered brain-targetable by the liposome encapsulation strategy. Taken together, the work updates the mining strategy and biosynthetic complexity of RiPPs to unravel an antiparkinsonian drug candidate valuable for combating Parkinson's disease that is globally prevailing in an alarming manner.

Polycystic ovary syndrome （PCOS） is a reproductive endocrine disorder characterized by coexisting reproductive dysfunction and glucolipid metabolic disturbance， affecting 8%-13% of women of reproductive age and 3%-11% of adolescent females. Due to the highly heterogeneous clinical features， symptom-oriented individualized strategies are commonly adopted for the treatment of PCOS. Chronic low-grade inflammation is one of the core mechanisms for the occurrence of PCOS. Macrophages， as foundational cells of innate immunity， play an indispensable role in modulating systemic inflammatory responses. The imbalance of macrophage M1/M2 polarization is involved in chronic low-grade inflammation in PCOS via pathways such as activating pro-inflammatory responses， disrupting ovarian tissue repair， stimulating excessive synthesis of androgens， and promoting the occurrence of insulin resistance. Reshaping the phenotype of macrophages might serve as a potential therapeutic strategy for PCOS. Traditional Chinese medicine （TCM） holds that spleen deficiency and phlegm dampness is a crucial pathogenesis of PCOS. The spleen， being in charge of defensive function， plays a key role in ensuring normal physiological functions such as transportation and defense against external pathogen during the occurrence and development of PCOS. The imbalance of macrophage polarization resembles the transition from spleen being in charge of defensive function to spleen losing its defensive role in TCM. Therefore， this paper， for the first time， explores the deep connection between macrophage polarization and the pathogenesis of chronic low-grade inflammation in PCOS from the TCM theory of spleen being in charge of defensive function， providing theoretical support and new research directions for the treatment and drug research of PCOS.

Objective To observe the expression of adhesion molecule CD226 on the small intestinal group 3 innate lymphoid cells (ILC3) in mice. Methods The bioinformatics was used to analyze the expression of CD226 on murine ILCs. Small intestinal mucosal lamina propria lymphocytes (LPL) were isolated from wild-type C57BL/6J mice, and the expression of CD226 on ILC1 and ILC3 was detected by flow cytometry. A mouse model of dextran sulfate sodium (DSS)-induced colitis was constructed to observe the changes in the expression of CD226 on ILC3. Results Both ILC1 and ILC3 in the mice small intestine expressed CD226 molecules; the proportion of ILC3 was reduced, while the expression level of CD226 on ILC3 was increased in the colitis model. Conclusion CD226 is expressed on the small intestines of mice, and although the proportion of ILC3 decreases in the DSS-induced colitis, the expression of CD226 on ILC3 increases.

OBJECTIVE To study the inhibitory effect and mechanism of curcumin and its derivatives A and B on TGF-β induced LX-2 cell fibrosis. METHODS Established the liver fibrosis model of LX-2 cells induced by TGF-β(10 ng·mL−1).The effects on cell proliferation were detected by CCK-8. The effects on cell apoptosis was detected by flow cytometry. The effects on fibrosis related factors(Collagen I, Collagen Ⅳ, Fibronectin, Vimentin, α-SMA, PDGFRβ, TGFβR1, TGFβR2, MMP2, MMP9, TIMP1 and TIMP2) protein expression and gene transcription levels were detected by Western blotting and q-PCR. RESULTS The curcumin and its derivative A and B had the inhibition effects on normal LX-2 cells, and the IC25 values were 15.7, 2.6, 10.2 μmol·L−1, respectively. Compared to the model group, the curcumin(15.7 μmol·L−1) and its derivative A(2.6 μmol·L−1) and B(10.2 μmol·L−1) had the significant inhibition effects on cell proliferation of the TGF-β induced LX-2 cells(P<0.05). The cell apoptosis rate of curcumin derivative B group was higher than the model group(P<0.05). Collagen I, Fibronectin, Vimentin, α-SMA, TGFβR1 and TIMP-1 protein expression levels in curcumin group were lower, while the protein expression level of MMP-9 was higher(P<0.05). The protein expression levels of Collagen I, Collagen IV, Fibronectin, Vimentin, α-SMA, TIMP-1 and TIMP-2 in curcumin derivative A group were lower, while the protein expression level of MMP-2 was higher(P<0.05). The protein expression levels of Collagen I, Collagen IV, Fibronectin, Vimentin, α-SMA, PDGFRβ, TGFβR1, TGFβR2, TIMP-1 and TIMP-2 in curcumin derivative B group were lower, while the protein expression level of MMP-2 was higher(P<0.05). The gene transcription levels of Collagen I, Fibronectin, α-SMA and TIMP-1 in curcumin group were lower(P<0.05). The gene transcription levels of Collagen I, Fibronectin and α-SMA in curcumin derivative A and B groups were lower(P<0.05). CONCLUSION Curcumin and its derivatives A and B inhibit the abnormal activation and proliferation of TGF-β-induced LX-2 cells, inhibit the excessive secretion and accumulation of its extracellular matrix components, and promote its degradation, thus playing an anti-fibrotic effect in vitro, especially the curcumin derivative B.

Ancylostoma ceylanicum is a zoonotic soil-derived nematode that parasitizes the intestines of humans and animals (dogs and cats), leading to malnutrition and iron-deficiency anemia. Helminth parasites secrete calreticulin (CRT), which regulates or blocks the host’s immune response. However, no data on A. ceylanicum calreticulin (Ace-CRT) are available. We investigated the biological function of recombinant Ace-CRT (rAce-CRT). rAce-CRT showed reliable antigenicity and stimulated the proliferation of mouse splenocytes and canine peripheral blood mononuclear cells. Quantitative reverse-transcription PCR assays revealed that rAce-CRT primarily promoted the expression of T helper 2 cytokines, particularly IL-13, in canine peripheral blood lymphocytes. rAce-CRT inhibited complement-mediated sheep erythrocyte hemolysis in vitro. Our findings indicate that Ace-CRT plays an immunomodulatory role and may be a promising candidate molecule for a hookworm vaccine.

Primary cardiac angiosarcoma is a type of soft tissue sarcoma originating in vascular endothelial cells, without obvious gender differences in the incidence rate and specific early clinical manifestations, whilstpericardial effusion often found at the first presentation of most patients. Tumors are mostly located in the right atrium and pericardium. Echocardiography is the preferred examination method for diagnosing cardiac angiosarcoma and multimodal imaging is important in the diagnosis and differential diagnosis of benign and malignant cardiac mass. This article retrospectively analyzes the 25 cases of clinical manifestations and imaging features of primary cardiac angiosarcoma.

Objective:To compare the dose distribution among CyberKnife, Tomotherapy, Edge, Triology and γ-knife in stereotactic body radiation therapy (SBRT) for pancreatic cancer.Methods:Clinical data of 10 panreatic cancer patients receiving CyberKinife treatment were retrospectively analyzed. The treatment plans were designed by five apparatuses from five centers according to the uniform requirement. All plans were transferred to MIM system for the extraction of parameters, which mainly included D min, D mean and D max of PTV, conformity index (CI), new conformity index (nCI), homogeneity index (HI), gradient index (GI), coverage, D max and dose-volume of the stomach and bowel. Results:The best CI and nCI were obtained in Triology ( P<0.001), and the worst HI was found in γ-knife ( P<0.001). The best GI was found in CyberKnife, followed by γ-knife and Tomotherapy, and Edge showed the worst GI ( P<0.001). The highest D min of PTV was found in both Edge and Triology, while lower D min of PTV was found in CyberKnife and Tomotherapy ( P<0.001). Additionally, γ-knife provided the highest D mean and D max of PTV ( P<0.001). Regarding the organs at risk, the lowest D max and D 5cm 3 of the bowel ( P<0.001), D max of the stomach ( P=0.003), D max( P=0.001), D 5cm 3 ( P<0.001) and D 10cm 3 ( P=0.005) of the duodenum, D max( P<0.001) and D 0.35cm 3 ( P<0.001) of the spinal cord were found in CyberKnife.
