Objective To put forward relevant national legislative proposals for preventing workplace violence (WPV) in the healthcare industry by comparing the current legal practices of China and the United States. Methods The Workplace Violence Prevention for Health Care and Social Service Workers Act (hereinafter referred to as the "Act") of the United States was translated and analyzed. The relevant normative legal documents in China were systematically reviewed to compare the legislative differences in the prevention and control of WPV against health care workers. Results The Act aims to establish an employer-driven legal framework for WPV prevention and control. China has no specific legislation for WPV, but has established partial legislation for protecting healthcare workers from external violence through various legal practices. The "Act" regards WPV as an occupational hazard and adopts the priority control order to carry out the prevention and control of WPV. In contrast, China's legislation for WPV approach emphasizes public security and undermines occupational health, treating WPV merely as a work-related injury or accident with limited protection. This gap reveals divergent priorities for legal interests. Conclusion China should integrate WPV prevention and control into the occupational health legal framework through revising existing laws, advancing dedicated legislation, and ratifying relevant international conventions, to strengthen the occupational health legal system. All stakeholders should clarify the responsibilities for WPV prevention and control of healthcare workers, and ensure comprehensive legislative response.

BACKGROUND:Abnormal extracellular matrix accumulation and excessive proliferation of fibroblasts are the main manifestations of pathological scars.Excessive proliferation of fibroblasts leads to the production of large amounts of collagen-based extracellular matrix.Therefore,to investigate the role of fibroblast fibrosis in the formation of pathological scar will provide a new idea for revealing the mechanism of pathological scar and biological therapy. OBJECTIVE:To investigate the effect of RAS-selective lethal small molecule 3(RSL3)on the fibrosis of human pathological scar fibroblasts. METHODS:Then cases of pathological scar tissue and normal skin tissue samples from the same individuals,provided by the Department of Burn Plastic Surgery,General Hospital of Ningxia Medical University,were collected.Fibroblasts of human pathological scar and human normal skin were extracted and used in the following experiments.The general condition of the pathological scar tissue and the normal skin tissue was detected by hematoxylin-eosin staining.The appearance of fibroblasts from pathological scar and normal skin were observed by inverted microscope.The fibroblasts were verified by immunofluorescence assay.The cells were treated with different concentrations of RSL3(1,3,5,7,9,11,13 μmol/L).The inhibitory concentration of RSL3 on fibroblasts was detected by cell counting kit-8.Control group(without treatment)and RSL3 intervention group(treated with 7 μmol/L RSL3 for 24 hours)were set up.The mRNA and protein expressions of glutathione peroxidase 4,type Ⅰ collagen,type Ⅲ collagen and α-smooth muscle actin were detected by Qrt-PCR and western blot,respectively.Level of malondialdehyde in cells was detected.The residual scratch area was measured by cell scratch test after 24 hours to calculate the percentage of residual scratch area. RESULTS AND CONCLUSION:The expression of glutathione peroxidase 4 in the pathological scar group was higher than that in the normal skin group(Mrna:t=3.252,P<0.01;protein:t=5.075,P<0.01).The expression of glutathione peroxidase 4 in the pathological scar fibroblast group was higher than that in the normal skin fibroblast group(Mrna:t=10.32,P<0.01;protein:t=26.22,P<0.01).Compared with the control group,the expression of glutathione peroxidase 4 was decreased(Mrna:t=2.798,P<0.05;protein:t=4.643,P<0.01),the content of malondialdehyde was increased(t=2.917,P<0.05),the expression of type Ⅰ collagen(Mrna:t=15.84,P<0.01;protein:t=4.610,P<0.01),type Ⅲ collagen(Mrna:t=28.86,P<0.01;protein:t=7.713,P<0.01)and α-smooth muscle actin(Mrna:t=2.671,P<0.05;protein:t=7.417,P<0.01)were decreased in the RSL3 intervention group.Compared with the control group,the migration ability was weakened in the RSL3 intervention group(t=14.06,P<0.01).To conclude,RSL3 can inhibit the expression of glutathione peroxidase 4 and then inhibit the ability of fibrosis and migration of pathological scar fibroblasts.

Objective:To investigate the correlation between the level of treponema pallidum specific antibodies(TPAb)and immunoglobulin A/E/M/G(IgA/E/M/G)and IgG subtypes in active syphilis patients,so as to provide a basis for the comprehensive di-agnosis and treatment and prognosis evaluation of clinical syphilis.Methods:Active syphilis patients admitted to the First Affiliated Hospital of Soochow University in 2023 were divided into 1∶4+and 1∶16+groups according to the syphilis toluidine red unheated se-rum test(TRUST),and healthy control group were selected for the detection of TPAb by chemiluminescence microparticle immunoas-say(CMIA).The contents of IgA/E/M/G and IgG1/2/3/4 were determined by immunoturbidimetry.Results:A total of 206 patients with active syphilis(125 males and 81 females)aged(46.05±19.58)years were included in this study.Compared with the healthy control group,IgG2 was decreased and TPAb,IgA/E/M/G and IgG1/3/4 levels were increased in the active syphilis group,with statistically significant differences in TPAb,IgE and IgG1/2/3 levels(P<0.05).Compared with the healthy control group,TRUST 1∶4+group had statistical differences in TPAb,IgE and IgG2,and TPAb was significantly correlated with IgE and IgG2/4.The levels of TPAb,IgA/E/M/G and IgG1/2/3 in TRUST 1∶16+group were statistically significant,and TPAb was significantly correlated with IgE and IgG4(P<0.05).In addition,there were significant differences in TPAb,IgG and IgG1/3 between the two positive groups(P<0.05).Conclu-sion:The levels of TPAb and Ig in active syphilis patients with different TRUST titers are significantly different.TPAb combined with Ig can be used to monitor the strength of syphilis activity,IgA/M/G and IgG1/3 may be candidate biomarkers.

Objective To investigate the relationship between spicy diet and uremic pruritus(UP)in the patients with maintenance haemodialysis(MHD).Methods A total of 403 patients receiving the treat-ment in the blood purification center of this hospital from December 2023 to February 2024 were selected as the study subjects and grouped by the sum of the scores of frequency and degree of pepper intake.The visual analogue rating scale(VAS)was used to conduct the preliminary pruritus score in all patients,and the pa-tients with the score＞0 point conducted the multidimensional evaluation by the 14-item uremic skin pruritus scale.The blood routine and itch-related blood biochemical indexes levels of all patients were measured.Results There were 65 cases in the bland diet group,119 cases in the mild spicy diet group and 219 cases in the spicy diet group,and there was no significant difference in the number of genders between the groups(P＞0.05).There were statistically significant differences in age,dialysis age and lymphocyte count among the groups(P＜0.05).There was no statistically significant difference in the degree of pruritus among the groups(Z=9.301,P=0.157),but it was seen that the proportion of moderate and severe pruritus in the mild spicy diet group and the spicy diet group was decreased,and the proportions of no pruritus and mild pruritus showed the increasing trend.The itching score of the bland diet group was higher than that of the mildly spicy diet group and spicy diet group,and the difference was statistically significant(P＜0.05),but there was no statistically significant difference between the mild spicy diet group and spicy diet group(P＞0.05).There was a statistically significant difference in the itch score of the patients aged 40-60 years in each group(P＜0.05),and there was no statistically significant difference in the itch score between the patients aged＞60 years old and＜40 years old in each group(P＞0.05).There was no statistically significant difference in the itch-related blood biochemical indexes among the groups(P＞0.05).Conclusion The spicy diet may reduce the degree of pruritus in patients with MHD,moreover which is not affected by the age and other factors,and may be associated with lymphocyte level decrease in the patients.

This study was to investigate the relationship between spring pollen distribution concentration, species and the detection results of air-borne pollen allergens in Taiyuan City, Shanxi Province during March to May 2022 and March to May 2023.A retrospective study was conducted in the Otorhinolaryngology Head and Neck Surgery Clinic of the First Hospital of Shanxi Medical University.Pollen particles will be monitored by gravity sedimentation method on the roof of the outpatient department of the First Hospital of Shanxi Medical University in downtown Taiyuan from March to May 2022-2023, and pollen species and quantity will be observed and recorded under an optical microscope.The air-borne pollen allergen detection results of all allergic rhinitis patients in the otolaryngology Head and Neck surgery Department of the First Hospital of Shanxi Medical University were extracted from the relevant outpatient system. SPSS software and Pearson correlation analysis were used to compare the correlation between the allergens and the dominant air-borne pollen monitoring results. Results are as follows: (1)A total of 18 species of spring pollen in Taiyuan City were monitored in 2022-2023, with 101 177.5 grains, and the dominant airborne pollen was poplar (16.69%) and pine (29.06%) pollen. The pollen of poplar (11.96%), elm (7.89%) and cypress (8.68%) were dominant in early spring; Pine (25.16%) pollen predominated in late spring. The two peaks of pollen dispersal in Taiyuan were in late March (15 479 grains) and early and mid May (15 094/15 343 grains).(2) The positive rates of allergens in serum specific IgE detection were: wormwood (46%, 248/541 cases), tree combination (26%, 143/541 cases), ragweed (19%, 101/541 cases), humulus scandens (9%, 49/541 cases).(3)There was a linear positive correlation between the positive rate of air-borne pollen allergens in allergic rhinitis patients in the Department of Otolaryngology Head and Neck Surgery in the First Hospital of Shanxi Medical University and the dominant air-borne pollen concentration in the same period ( P<0.05, r=0.999). In conclusion, two spring pollen dispersal peaks were formed in late March and early to mid May in Taiyuan City, and the dominant air-borne pollens were poplar and pine pollens. The positive rate of air borne pollen allergen sIgE showed that wormwood allergy was the highest.There was a positive correlation between the concentration of air-borne pollen and the positive rate of air-borne pollen allergens in patients with allergic rhinitis in the Department of otorhinolaryngology and head and neck surgery in Taiyuan in 2022 and 2023.The monitoring of pollen distribution in spring can provide an important scientific basis for clinical workers to formulate prevention and treatment plans for patients with allergic rhinitis in the season, and provide data reference for the epidemiological investigation of allergic diseases in Taiyuan in the future.

The stimulator of interferon genes(STING),an integral adaptor protein in the DNA-sensing pathway,plays a pivotal role in the innate immune response against infections.Additionally,it presents a valuable therapeutic target for infectious diseases and cancer.We observed that fangchinoline(Fan),a bis-benzylisoquinoline alkaloid(BBA),effectively impedes the replication of vesicular stomatitis virus(VSV),encephalomyocarditis virus(EMCV),influenza A virus(H1 N1),and herpes simplex virus-1(HSV-1)in vitro.Fan treatment significantly reduced the viral load,attenuated tissue inflammation,and improved survival in a viral sepsis mouse model.Mechanistically,Fan activates the antiviral response in a STING-dependent manner,leading to increased expression of interferon(1FN)and interferon-stimulated genes(ISGs)for potent antiviral effects in vivo and in vitro.Notably,Fan interacts with STING,preventing its degradation and thereby extending the activation of IFN-based antiviral responses.Collectively,our findings highlight the potential of Fan,which elicits antiviral immunity by suppressing STING degra-dation,as a promising candidate for antiviral therapy.
