OBJECTIVETo review the clinical features of acute toxicity of aromatic amino and nitro compounds.

METHODSA total of 110 papers reporting 1240 cases of acute toxicity induced by aromatic amino and nitro compounds from 1979 to 2013 were collected from CNKI, VIP, and Wanfang database, and were analyzed in this study.

RESULTSOf all included cases, 939 were caused by occupational exposure, and 301 were caused by exposure in daily life. A total of 1044 cases were male, and 196 were female. Age ranged from 9 days to 75 years. There were 13 cases of contact reaction. The numbers of mild, moderate, and severe toxicities were 358, 348, and 139, respectively, and the other 382 cases were not graded for severity. The average incubation period was 4.50±5.71 h (M = 3 h). The average incubation period of aniline toxicity was significantly shorter than that of nitrobenzene toxicity. Methemoglobinemia was found in 1146 cases, while cases of poisonings with 5-nitro-o-toluidine, 2-methyl-4-nitroaniline, and 3-chloro-2-methyl aniline were not found to have methemoglobinemia. The detection rates of MHb and HzB were 83.73% (674/805) and 40.19% (129/321), respectively. Sixty-two (19.31%) out of 321 cases were complicated by intravascular hemolysis, 270 (30.93%) out of 873 cases suffered hepatic impairment, 50 (12.25%) out of 408 cases were accompanied by renal damage. Consciousness disorders were found in 66 cases, and chemical cystitis was found in 36 cases. Oral poisoning could immediately induce severe symptoms including cyanosis, unconsciousness, and hemolysis. In prognosis analysis, it was found that the cure rate was 98.71% (1224/1240), and 14 cases of death were caused by multiple organ dysfunction syndrome, renal failure, uncontrolled hemorrhagic shock, myocardial infarction, and sudden death. Two cases were left with neurological sequelae.

CONCLUSIONThe clinical manifestations of poisoning with aromatic amino and nitro compounds are methemoglobinemia, intravascular hemolysis, liver damage, and renal damage. Treatment with specific medicine methylene blue can produce ideal clinical prognosis, but severe poisoning may cause death from multiple organ failure.

The efficient immobilization of capture antibodies is crucial for timely pathogen detection during global pandemic outbreaks.Therefore,we proposed a silica-binding protein featuring core functional domains(cSP).It comprises a peptide with a silica-binding tag designed to adhere to silica surfaces and tandem protein G fragments(2C2)for effective antibody capture.This innovation facilitates precise site-directed immobilization of antibodies onto silica surfaces.We applied cSP to silica-coated optical fibers,creating a fiber-optic biolayer interferometer(FO-BLI)biosensor capable of monitoring the monkeypox virus(MPXV)protein A29L in spiked clinical samples to rapidly detect the MPXV.The cSP-based FO-BLI biosensor for MPXV demonstrated a limit of detection(LOD)of 0.62 ng/mL in buffer,comparable to the 0.52 ng/mL LOD achieved using a conventional streptavidin(SA)-based FO-BLI biosensor.Furthermore,it achieved LODs of 0.77 ng/mL in spiked serum and 0.80 ng/mL in spiked saliva,exhibiting no cross-reactivity with other viral antigens.The MPXV detection process was completed within 14 min.We further proposed a cSP-based multi-virus biosensor strategy capable of detecting various pandemic strains,such as MPXV,the latest coronavirus disease(COVID)variants,and influenza A protein,to extend its versatility.The proposed cSP-modified FO-BLI biosensor has a high potential for rapidly and accurately detecting MPXV antigens,making valuable contributions to epidemiological studies.

OBJECTIVETo analyze the clinical features and investigate the clinical diagnostic methods of hard metal lung disease (HMLD), then provide reference for the diagnostic criteria of occupational HMLD.

METHODSRetrieved the open published case reports associated with HMLD from January, 2000 to June, 2014. Regarding the ages, sex, types and years of work, clinical features and laboratory results for analyzing.

RESULTSCollected 21 clinical cases of HMLD belonged to 6 internal reports and 15 oversea reports. Among them 15 male and 6 female, ages were from 22 to 58, length of service between 1 year and 43 years. Clinical presentations included cough (20 cases), dyspnea on progressive (10 cases), and pulmonary function testing showed a restrictive abnormality. The imaging features presented as bilateral areas of ground-glass attenuation, diffuse small nodules, extensive reticular opacities and traction bronchiectasis. The finding of giant cell interstitial pneumonia (GIP) was almost pathognomonic for hard metal pneumoconiosis. The main pathological findings contained a different levels of lymphocyte, acidophilic cell infiltration, hyperplasia of fibrous tissue and numerous large multinucleated histiocytes which ingested inflammatory cells were admixed with macrophages. 16 cases of the 21 reports showed GIP.

CONCLUSIONSClinical presentations include cough and dyspnea on progressive, and pulmonary function testing show a restrictive abnormality. The imaging features present as bilateral areas of ground-glass attenuation, areas of consolidation, diffuse small nodules, extensive reticular opacities and traction bronchiectasis. The prime pathological findings contain interstitial pneumonia with intra-alveolar macrophages and a large amount of multinucleated histiocytes.

Waterborne viruses that can be harmful to human health pose significant challenges globally,affecting health care systems and the economy.Identifying these waterborne pathogens is essential for preventing diseases and protecting public health.However,handling complex samples such as human and waste-water can be challenging due to their dynamic and complex composition and the ultralow concentration of target analytes.This review presents a comprehensive overview of the latest breakthroughs in waterborne virus biosensors.It begins by highlighting several promising strategies that enhance the sensing performance of optical and electrochemical biosensors in human samples.These strategies include optimizing bioreceptor selection,transduction elements,signal amplification,and integrated sensing systems.Furthermore,the insights gained from biosensing waterborne viruses in human sam-ples are applied to improve biosensing in wastewater,with a particular focus on sampling and sample pretreatment due to the dispersion characteristics of waterborne viruses in wastewater.This review suggests that implementing a comprehensive system that integrates the entire waterborne virus detection process with high-accuracy analysis could enhance virus monitoring.These findings provide valuable insights for improving the effectiveness of waterborne virus detection,which could have sig-nificant implications for public health and environmental management.

Cognitive decline is one of the main clinical symptoms of neurodegenerative diseases. There is no specific drug treatment, which seriously affects the quality of life and rehabilitation process of these patients. Non-invasive brain stimulation (NIBS) technology such as transcranial magnetic stimulation and transcranial electrical stimulation known as its advantages of non-invasive, painless, and easy to operate, has been used in clinical treatment of cognitive disorders. In particular, it has a good effect on improving cognitive functions such as memory, attention, orientation and language ability. In recent years, the study of cerebellar involvement in learning and memory through brain-cerebellar circuit has attracted much attention, and cerebellum has become a new target for NIBS technology exploration. However, the correlation between cerebellar NIBS and cognitive function regulation is still unclear. This paper aims to provide the evidences of the anatomic and functional basis of cerebellar involvement in cognitive function regulation and cerebellar non-invasive stimulation on cognitive function regulation.

Alzheimer's disease(AD)is a neurodegenerative disease characterized by progressive cognitive dysfunction and behavioral impairment,with a lack of effective drug treatment.Transcranial magnetic stimulation(TMS)is a non-invasive brain stimulation technique,and its role in regulating and improving cognitive function has become increasingly prominent.Previously,the targets of TMS stimulation were focused on the cerebral cortices,but emerging evidence suggests that cerebellum stimulation could not only regulate the motor cortex but also regulate and integrate the distant cognitive-related cerebral regions.Consequently,the cerebellum has gradually emerged as a potential non-invasive therapeutic target for cognitive rehabilitation in AD.This article summarizes the anatomical and functional basis of the cerebellum's involvement in cognitive function regulation,as well as the research progress on TMS modulation of cognitive function mediated by the cerebellum.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.
