Arsenic (organoarsenic) compound is one of the oldest drugs used by humans to treat various diseases. From its initial application in treating various skin diseases to the 1970s when arsenic trioxide (ATO) was proven to be able to significantly relieve acute promyelocytic leukemia (APL), arsenic (organoarsenic) compounds gradually occupied an important position in the history of medical development. This article reviews the pharmaceutical research progress of inorganic arsenic compounds and organic arsine compounds, covering anticancer, antiparasitic, antiviral and antibiotic aspects. It further explores the potential for developing new arsenic (organoarsenic) drugs with higher efficacy and lower toxicity, aiming to provide new research directions and ideas for the application of arsenic (organoarsenic) compounds in disease treatment.

Objective:To explore the association between the gross motor development of children and Chi-nese developmental dyslexia.Methods:A total of 54 children were enrolled,indadit 27 children with Chinese DD and 27 age-gender-matched normal children.The Test of Gross Motor Development-Third Edition(TGMD-3),and the balance tests from the Movement Assessment Battery for Children(M-ABC)were used to evaluate the children's gross motor development level.Children's reading ability was evaluated by primary school students'literacy test question bank,one-minute reading task,and the Reading Test on Pupils.Results:The overall analysis of motortests showed that the grossmotor total score,locomotor score,object control score,and balance score in the DD group were significantly lower than those in the normal control group(P＜0.05).Logistic regression analysis revealed a negative association between balance scores,locomotor scores,object control scores,TGMD-3 total scores and indi-viduals with dyslexia(OR=3.08,1.35,1.16,1.13,Ps＜0.05).Conclusion:The delayed gross motor development of children is associated with the occurrence of Chinese developmental dyslexia.

Objective To investigate the value of neutrophil to lymphocyte ratio(NLR)and lymphocyte to monocyte ratio(LMR)in the diagnosis and prognosis of patients with sepsis.Methods From January 2022 to December 2022,patients in the First Affiliated Hospital of Soochow University were recruited in this study,including 47 patients with sepsis(sepsis group),31 with infection but not diagnosed as sepsis(infection group),and 25 healthy individuals(control group)were simultaneously chosen.Patients with sepsis were assigned to non-shock group(32 cases)or shock group(15 cases),survivors group(38 cases)or deaths group(9 cases).Procalcitonin(PCT),C-reactive protein(CRP)and routine blood tests were analyzed and compared between groups.Spearman's correlation test was used to analyze the correlation among NLR,LMR and PCT,PCR,lymphocyte,monocyte,neutrophil,platelet and SOFA scores,the diagnostic value of NLR and LMR in sepsis was evaluated by plotting the receiver operating characteristic(ROC)curve.Results The NLR was 12.54(7.53,23.42)in sepsis group,3.85(1.83,5.64)in infection group,and 1.71(1.39,2.20)in normal control group.The corresponding LMR was 1.58(1.07,3.03),2.81(1.53,4.76),and 5.16(4.04,6.59),respectively.NLR was negatively correlated with LMR(rs=-0.469,P＜0.05).The NLR on day 7(NLR7)was 6.56(3.90,10.72)in the non-shock group and 15.20(7.53,27.31)in shock group.The corresponding △NLR7 was-1.64(-5.75,0.41)and 1.98(-0.48,13.79)in the two groups.The shock group had significantly higher △NLR7 than the non-shock group(P＜0.05).NLR7 was 7.10(4.09,12.96)in the survivors and 15.20(10.45,32.82)in the deaths group.The corresponding △NLR7 was-0.65(-5.58,1.58)and 5.02(-1.12,17.06)in the two groups.The deaths group had significantly higher △NLR7 than the survivors group(P＜0.05).The LMR on day 7(LMR7)was 2.22(1.64,3.78)in the non-shock group and 1.29(0.66,2.03)in shock group.The corresponding △LMR7 was 0.38(-0.37,1.17)and-0.19(-0.78,0.25)in the two groups.The shock group had significantly lower △LMR7 than the non-shock group(P＜0.05).LMR7 was 2.12(1.49,3.42)in the survivors group and 1.09(0.53,1.78)in the deaths group.The deaths group had significantly lower LMR7 than the survivors group(P＜0.05).The AUC of NLR was 0.959 1(95％CI:0.910 5-1.000 0)in diagnosis of sepsis.The best cut-off value was 4.16.The A UC of LMR was 0.913 6(95％CI:0.846 4-0.980 8)in diagnosis of sepsis.The best cut-off value was 3.21.Conclusions NLR and LMR can be used to evaluate the severity and prognosis of patients with sepsis.These two markers may play a role in the diagnosis of sepsis.

Objective:To analyze the mediating effect of cardiovascular health status (CVH) on the association between educational level and cardiovascular disease (CVD).Methods:The participants were from Shanghai Suburban Adult Cohort and Biobank, and questionnaire survey, physical examination, blood biochemistry were conducted from 2016 to 2020 for baseline information collection, and follow up was conducted until March 31, 2024 based on the medical data, CVD incidence data and death surveillance data at different levels. The associations of educational level, CVH and time to CVD onset of the study population were analyzed using the accelerated failure time model to analyze the mediating effects of CVH, health behaviors, and health factors in the association of educational level and time to CVD onset. The mediating effects of educational level, gender, and age moderated associations were also analyzed.Results:A total of 57 312 participants were included, with 2 780 new cases of CVD during a median follow-up of 6.71 (6.71-6.72) years, and a mean incidence density of 7.77/1 000 person-years (95% CI: 7.48/1 000 person-years -8.06/1 000 person-years). In total, the less educational level and the lower CVH, the higher CVD incidence density ( P<0.05). The results of accelerated failure time models showed that the time ratio for CVD-free survival was 1.15 (95% CI: 1.06-1.24) and 1.33 (95% CI: 1.10-1.60) for moderate and high educational level, respectively. The results of the mediation effect analysis showed that the association between moderate and high educational level and time to CVD onset was 29.60% (20.50%-50.00%) and 36.10% (23.80%-59.00%), 9.97% (5.07%-20.00%) and 13.84% (6.84%-29.00%), 15.24% (9.64%-27.00%) and 17.55% (11.58%-33.00%) of mediators mediated by CVH, health behaviors, health factors, respectively. Among them, there was an exposure-mediated interaction of educational level and a positive moderating effect of age. Conclusion:CVH, health behaviors and health factors had a proportionate mediating effect in the association between educational level and risk of CVD development.

Antibiotics are chemicals with bactericidal or bacteriostatic activity produced by microorganisms and artificially synthesized. Since the discovery of penicillin by Alexander Fleming in 1928, antibiotics have been widely used in clinical treatments as well as in the animal husbandry and aquaculture, leading to antibiotic residues in soil, water, food and other environments. At the same time, antibiotic resistance is increasingly serious, which necessitates the discovery of novel antibiotics. In recent years, with the development of synthetic biology, researchers have developed a variety of whole-cell biosensors that can respond to antibiotics. These whole-cell biosensors use microbial cells to convert antibiotic signals into readable signals, which can not only perform dynamic detection of antibiotics simply, quickly, sensitively and accurately but also effectively discover novel antibiotics. This review comprehensively summarizes the reported whole-cell biosensors for antibiotics, classifies them into two types (specific and general), and elaborates on the design principles and applications of the two types of antibiotic biosensors. This review will provide reference for the construction and application of other whole-cell biosensors for antibiotics.

ObjectiveTo analyze the incidence and influencing factors of postherpetic neuralgia (PHN) among herpes zoster (HZ) patients aged 50 years and above in the community-based population of Shanghai who had not received the recombinant zoster vaccine (RZV), so as to provide data support for formulating PHN prevention strategies. MethodsBased on baseline survey data, physical examinations, biochemical indicator tests, annual clinical diagnosis and treatment data from the Shanghai Suburban Adult Cohort, as well as the RZV vaccination data from the vaccination information platform of the Center for Disease Control and Prevention, the cumulative incidence rate of PHN was calculated. Logistic regression analyses were used to analyze the influencing factors of PHN. ResultsA total of 48 261 participants were included in this study, with 2 406 newly diagnosed HZ cases, among whom 11 had received at least one dose of RZV. Among 2 395 unvaccinated HZ patients, 262 new PHN cases were identified, with a cumulative incidence rate of 10.94% (95%CI: 9.72%‒12.26%). Factors influencing PHN incidence included age 70‒79 years (OR=2.069, 95%CI: 1.427‒3.028), history of immunosuppresant utilization (OR=1.592, 95%CI: 1.227‒2.072), and history of stroke (OR=1.657, 95%CI: 1.015‒2.605). For male patients, the influencing factors for PHN were age 70‒79 years (OR=2.319, 95%CI: 1.195‒4.802) and history of chronic bronchitis (OR=1.935, 95%CI: 1.010‒3.517), whereas, for female patients, age 70‒79 years (OR=1.767, 95%CI: 1.107‒2.831), history of immunosuppresant use (OR=1.603, 95%CI: 1.151‒2.245), history of stroke (OR=1.906, 95%CI: 1.059‒3.277), and alcohol consumption (OR=3.698, 95%CI: 1.093‒12.517) were influencing factors for PHN. ConclusionIndividuals with advanced age, history of immunosuppresant utilization, stroke, chronic bronchitis, and alcohol consumption are at high risk for PHN. These individuals should be prioritized for RZV vaccination to reduce the occurrence of PHN and improve their quality of life.
