Objective To analyze the distribution features of newly reported cases of occupational welder′s pneumoconiosis (OWP) in Guangdong Province from 2013 to 2022. Methods Data of newly reported cases of OWP from National Occupational Disease Network Direct Reporting System of Guangdong Province from 2013 to 2022 was analyzed using conventional data analyzing Methods. Results A total of 294 cases of OWP were reported in Guangdong Province from 2013 to 2022 with an overall downward trend. The average age at diagnosis for new OWP cases was 44±6 years old, and the median of dust exposure duration was 11 years. Males accounted for 99.3% of the cases, and 94.2% of the cases were phase Ⅰ OWP. Guangzhou City had the highest regional distribution with 74.8% of the cases. The industry distribution was mainly manufacturing, accounting for 86.7% of the cases. The scale of enterprises was most common in small enterprises, followed by large and medium-sized enterprises, accounting for 38.4%, 30.6% and 24.5% of the cases respectively. The economic types of enterprises were mostly private enterprises, followed by state-owned enterprises, accounting for 54.1% and 32.0% of the cases respectively. Conclusion In Guangdong Province, the newly reported OWP cases were clustered in terms of disease stage, regional distribution, industry, enterprise scale and enterprise economic type. There was a tendency of younger age at diagnosis and shorter dust exposure duration.

Objective: To analyze the status of occupational medical examination (OME) institutions in Guangdong Province and the critical control points affecting their future development. Methods: A total of 211 OME institutions registered in Guangdong Province were selected as the research subjects. Their current statue was investigated, and the risk assessment of their future development was carried out based on hazard analysis and critical control point theory. Results: The OME institutions were mainly concentrated in the Pearl River Delta, accounting for 72.0%. The public and private medical and health institutions accounted for 70.6% and 29.4% respectively. The filing rates of different OME categories from high to low in the order were physical factors, chemical factors, dust, other, radiation factors, biological factors (P<0.01), and the filing rates were 89.6%, 88.6%, 84.8%, 63.0%, 7.1% and 1.0%, respectively. The rates of excellence in the field assessment from high to low in the order were hearing atlas analysis personnel, lung function examination operators, chest film reading personnel, chief examination physician, technical director, quality director (P<0.01), and the rates of excellence were 49.4%, 26.2%, 20.6%, 10.8%, 8.2% and 4.6%, respectively. A total of 37 institutions did not submit OME information, of which 23 institutions did not carry out OME work after filing. The required diagnosis rate and confirmed diagnosis rate of suspected occupational diseases in 2020 were 34.3% and 55.3%, respectively. In 2021, the detection rate of suspected occupational diseases was only 1.1‰. Among the institutions with biological monitoring records, 64.1% did not participate in external quality assessment program in laboratory, and the unqualified rate of 38 participating institutions was 55.3%. The risk assessment results show that the future development of OME institutions needs to focus on private institutions, institutions that have not reported OME information, institutions that have missed diagnosis and missed reporting of suspected occupational diseases, institutions that have not participated in external quality assessment program in laboratory and core personnel such as quality managers, technical leaders, and main inspection physicians. Conclusion: OME institutions in Guangdong Province show the characteristics of centralized filing category, centralized filing region and centralized filing institution nature. Combined with the potential risks of OME institutional capacity building, it is necessary to implement classified management, strengthen information construction, supervision and management, implement post responsibilities, and promote the high-quality development of OME institutions.

Acute respiratory distress syndrome (ARDS) refers to acute diffuse lung injury caused by a variety of intrapulmonary and/or extrapulmonary factors such as infection and trauma. Uncontrolled inflammatory response is the main pathological feature. Different functional states of alveolar macrophages have different effects on inflammatory response. Transcription activating factor 3 (ATF3) is a fast response gene in the early stage of stress. In recent years, it has been found that ATF3 plays an important role in regulating the inflammatory response of ARDS by regulating the function of macrophages. This paper reviews the regulatory effects of ATF3 on alveolar macrophage polarization, autophagy and endoplasmic reticulum stress and its effects on the inflammatory process of ARDS, aiming to provide a new research direction for the prevention and treatment of ARDS.

The λ pattern is a rare electrocardiogram feature in clinical practice,which often indicates the occurrence of impending fatal ventricular tachyarrhythmias or sudden cardiac death.In this case,Holter monitoring recorded a progressive evolution of the λ pattern followed by advanced atrioventricular blocks in a patient with chest pain accompanied by syncope.λ sign occurred at the time of chest pain,and advanced atrioventricular blocks were recorded at the time of subsequent syncope.Coronary stenosis was detected in the left circumflex by coronary angiography.The patient recovered after stent implantation in the culprit vessel and related medications to prevent coronary spasm.Our case indicate that the λ pattern could occur prior advanced atrioventricular blocks-induced syncope in patient with ischemic heart disease.

High mobility group protein B1 (HMGB1), a highly conversed non-histone nucleoproteins with strong pro-inflammatory property, is one of the inflammatory mediator of the acute respiratory distress syndrome (ARDS). Numerous studies have confirmed that HMGB1 regulates ARDS by binding to receptor for advanced glycation end product (RAGE), Toll-like receptor (TLR) and etc. And it can significantly increase the mortality of ARDS. But the mechanism of HMGB1 release is still unclear. This study focuses on the HMGB1 release progress, which connected with Janus kinases/signal transducer and activator of transcription (JAK/STAT), nuclear factor-κB (NF-κB), Notch, inflammasome, tumor necrosis factor (TNF), mitogen-activated protein kinase (MAPK), reactive oxygen species (ROS), peroxisome proliferator-activated receptor (PPAR) and other signaling or dependent pathways in ARDS.

Objective To investigate the prediction by intravascular ultrasound (IVUS) with monocyte to high density lipoprotein-cholesterol (HDL-C) ratio (MHR) of 12-month prognosis in patients with intermediate non-left main coronary lesions after percutaneous coronary intervention (PCI). Methods Patients with intermediate non-left main coronary lesions diagnosed by coronary angiography were tested of monocyte counts and HDL-C levels at admission with MHRs calculated. IVUS was used to examine plaque stability in target lesions. Patients were dviided into stable plaque group (n=44) and unstable plaque group (n=140) according to the IVUS results. PCI was then operated in patients with unstable plaque or with minimum lumen area<4 mm2. The major adverse cardiovascular events (MACE) were recorded during the follow-up period of 12 months after PCI. Results MHR was significantly higher in unstable plaque group than that in stable plaque group[(22.6±8.4) vs.(14.1±7.2),P<0.001]. Receiver-operating characteristic (ROC) analysis revealed that an MHR cut-off of 16.05 had 74.2％ sensitivity and 77.0％ specificity for prediction of 12-month MACE after PCI (AUC 0.78, 95％ CI 0.71–0.85, P<0.001). Besides, unstable plaque with MHR over 16.05 was an independent risk factor for 12-month MACE after PCI (adjusted HR 3.26, 95％ CI 2.48–4.14, P=0.020). Conclusions IVUS combined with MHR is a valuable index predicting the prognosiso f patients with intermediate non-left main coronary lesions who underwent PCI.

?? [Abstract]? Objective? To explore the current status of spousal intimacy and role adaptation of neonatals' fathers and to investigate the correlation between their spousal intimacy and role adaptation. Methods? Totally 472 fathers of neonatals born in Yinzhou People's Hospital between January and May 2018 were selected by convenient sampling and investigated with Dyadic Adjustment Scale (DAS) and Father's Role Adaptation Scale (FRAS). The correlation between the two was analyzed. Results? The spousal intimacy score of the 472 fathers of neonatals was (119.34±16.52), and 30.93% of them showed bad spousal intimacy. Their role adaptation score was (75.80±9.03). Pearson correlation analysis showed that spousal intimacy and role adaptation of neonatals' fathers were positively correlated with each other (r=0.307,P＜ 0.05). Conclusions? Fathers' role adaptation process is full of pressure, and good spousal relationship helps to improve the role adaptation levels of neonatals' fathers.

Objective To investigate the influence of collateral circulation recruitment on cognitive functions in patients with severe unilateral stenosis or unilateral occlusion of the internal carotid artery by using TCD.Methods A total of 176 patients with severe unilateral stenosis or unilateral occlusion of the internal carotid artery were enrolled and were divided into a single vessel collateral group(n=80,45.5 ％),a multiple vessel collateral group(n=74,42.1％) and a no collateral group(n=22,12.5 ％).In order to study the influence of single vessel collateral circulation on cognitive functions,the single vessel collateral group was further divided into an anterior communicating subgroup(AcoA),a posterior communicating subgroup(PcoA),an ocular artery subgroup(OA),and a normal control subgroup.All patients and 34 normal controls(NC) received MoCA,and scores for the overall assessment and individual domains were analyzed.Results Compared with the control group (26.3± 1.1,4.7 ± 0.5,2.0 ± 0.0,3.6 ± 1.0),the multiple vessel collateral group,the single vessel collateral group and the no collateral group had lower overall scores (24.2 ± 1.7,21.9 ± 2.3,19.0 ± 2.4),lower executive/visuospatial function(3.9 ± 0.7,3.2 ± 0.8,2.4 ± 0.6),lower abstraction (1.7 ± 0.5,1.6±0.5,1.3±0.5),and lower delayed recall(2.9±0.8,1.9±0.8,1.6±0.5)(F=80.52,63.21,12,48.99,all P＜0.05);both collateral groups had lower scores in subtraction and attention (4.6±0.6 vs.5.2±0.7,4.3±0.7 vs.5.2±0.7);the no collateral group had lower scores in orientation(4.7±0.7 vs.5.7±0.5)(P＜0.05).Compared with the multiple vessel collateral group,both the single vessel collateral group and the no collateral group had lower overall scores(21.9±2.3 vs.24.2 ± 1.7,19.0± 2.4 vs.24.2 ± 1.7),executive/visuospatial function (3.2 ± 0.8 vs.3.9 ± 0.7,2.4±0.6 vs.3.9±0.7),subtraction and attention(4.6±0.6 vs.5.1±0.5,4.3±0.7 vs.5.1±0.5) (all P＜ 0.05);the no collateral group had lower scores in abstraction (1.3 ± 0.5 vs.1.7 ± 0.5),delayed recall(1.6 ± 0.5 vs.2.9 ± 0.8) and orientation (4.7 ± 0.7 vs.5.7 ± 0.5) (all P ＜ 0.05).Compared with the single vessel collateral group,the no collateral group had lower overall scores(19.0 ±2.4 vs.21.9±2.3),executive/visuospatial function(2.4±0.6 vs.3.2±0.8)and orientation(4.7± 0.7 vs.5.7 ± 0.6) (all P ＜0.05).In single vessel collateral patients,the AcoA subgroup had higher MoCAscores than the PcoA subgroup(22.9± 1.7 vs.21.2±2.7) (P＜0.05),and the AcoA subgroup had higher scores in delayed recall than the OA subgroup(2.2±0.8 vs.1.7±0.6) (P＜ 0.05).Conclusions Severe unilateral stenosis or unilateral occlusion in the internal carotid artery can result in cognitive impairment,especially in executive/visuospatial function,abstraction,delayed recall,subtraction and attention.However,collateral circulation can protect cognitive function in patients with unilateral internal carotid artery stenosis or occlusion and multiple vessel collateral circulation is more effective than single vessel collateral circulation,and AcoA is more effective than either PcoA or OA,but the difference between PcoA and OA is not significant.
