Objective:To explore mechanism of Caspase-11/GSDMD non-classical cell pyroptosis pathway in inflammatory response of RAW264.7 monocyte macrophages induced by ricin toxin.Methods:Cell pyroptosis model induced by LPS+Nigericin was used as a positive control,and cells were induced with 40 ng/ml and 80 ng/ml of ricin toxin for 8 hours.Cell release of lactate dehydro-genase(LDH)was measured by LDH cell release assay;cell viability was assessed by flow cytometry(Annexin Ⅴ/PI double staining);gene expressions of Caspase-11,GSDMD,IL-1β and IL-18 were measured by RT-qPCR;protein levels of Caspase-11 and GSDMD were measured by Western blot;secretion levels of inflammatory cytokines IL-1β and IL-18 in cell supernatant were measured by ELISA.Results:Compared with normal control group,RAW264.7 cells treated with ricin toxin showed swelling,cell membrane rupture,significantly increased LDH release(P<0.001),significantly increased pyroptosis rate(P<0.001),significantly increased expression of pyroptosis-related genes Caspase-11,GSDMD,IL-1β and IL-18(P<0.05),significantly increased protein expressions of Caspase-11 and GSDMD(P<0.05),and significantly increased secretion levels of IL-1β and IL-18 in cell supernatant(P<0.05).Results of ricin toxin treatment group were consistent with LPS+Nigericin cell pyroptosis positive control group.Conclu-sion:Ricin toxin may induce cell pyroptosis in RAW264.7 cells through Caspase-11/GSDMD non-classical pathway,thereby promoting inflammatory response.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

Objective To investigate the relationship between daily intake of monounsaturated fatty acids(MUFAs)and polyunsaturated fatty acids(PUFAs)and non-alcoholic fatty liver disease(NAFLD),and to determine the threshold values of daily MUFAs and PUFAs intake for NAFLD risk.Methods Date were collected from the Dryad database.We enrolled a total of 1 068 healthy subjects aged 18 years and older(534 in the control group and 534 with NAFLD group)who had physical check-up in the Affiliated Nanping First Hospital of Fujian Medical University from April 2015 to August 2017.Comprehensive medical histories were obtained through questionnaires;information on dietary intake was collected using a semi-quantitative food frequency questionnaire and daily MUFAs and PUFAs intake were calculated.Baseline characteristics were compared between the two groups,and Logistic regression and restricted cubic spline(RCS)analyses were used to explore the relationship between daily MUFAs or PUFAs intake and NAFLD.Results Compared with the control group,the prevalence of hypertension,tea drinking,body mass index(BMI),daily energy intake,and daily MUFAs and PUFAs intakes were significant higher in patients with NAFLD(all P＜0.05),but the proportion of physical activities was significantly lower(P＜0.05).Logistic regression analysis revealed that after adjusting other confounding factors such as age,gender and BMI,for every 10 g increase in daily MUFAs or PUFAs intake,the risk of NAFLD increased by 53％(95％ CI:1.25-1.87,P＜0.001)and 3.30 times(95％ CI:2.98-6.20,P＜0.001),respectively.RCS indicated an approximately linear relationship between daily MUFAs intake and NAFLD(P for nonlinearity=0.064)and a nonlinear relationship between daily PUFAs intake and NAFLD(P for nonlinearity＜0.05).Subgroup analysis results were generally consistent,and there was statistical evidence of interactions between MUFAs and factors such as gender,hypertension and education level,with interaction between PUFAs and BMI observed(P＜0.05).Conclusion Increased daily intake of MUFAs or PUFAs is significantly associated with an increased risk of NAFLD,and further research is needed to clarify their specific roles in hepatic lipid accumulation.

Objective:To construct bacterial cytoplasmic membrane nanovesicles(BMV)with overexpressing programmed death 1(PD-1),denoted as BMV-PD-1 and evaluate the targeting efficacy of BMV-PD-1 towards transplanted lung tumor tissues in mice.Methods:The fusion plasmid ClyA-PD-1-EGFP fused by PD-1 and Cytolysin A(ClyA)was transferred into Escherichia coli BL21-Codonplus through plasmid transformation.Laser confocal microscopy,SDS-PAGE,and WB were used to detect the expression of the fusion protein ClyA-PD-1-EGFP.Bacterial membranes were extracted and processed with an extruder to generate BMV-PD-1.TEM and NTA were utilized to assess the morphology,size distribution,and zeta potential of BMV-PD-1,while WB was used to verify the presence of PD-1 protein.Laser confocal imaging was conducted to monitor the uptake of BMV-PD-1 by Lewis lung cancer cells.A C57BL/6J mouse subcutaneous transplant tumor model of LLC lung cancer cells was constructed,and the tumor targeting of BMV-PD-1 was evaluated by small animal imaging system.Results:Laser confocal microscopy images demonstrated that the plasmid ClyA-PD-1-EGFP was transferred into BL21-Codonplus and successfully expressed into protein.SDS-PAGE results suggested that ClyA-PD-1-EGFP was overexpressed in BL21-Codonplus.WB analysis indicated that PD-1 was expressed in bacteria and highly expressed in BMV-PD-1(P<0.001).NTA and TEM analyses revealed that BMV-PD-1 were spherical vesicles with a diameter of(145±14)nm and a negative surface charge.Laser confocal imaging showed that the high expression of PD-1 significantly increased the uptake of BMV-PD-1 by lung cancer cells(P<0.01).In vivo imaging of small animals further confirmed that the high expression of PD-1 can effectively improve cancer targeting of BMV-PD-1(P<0.01).Conclusion:In this study,bacterial plasma membrane nanovesicles BMV-PD-1 with high PD-1 expression are successfully constructed,and it is found that PD-1 overexpression markedly improve the mouse lung cancer xenograft tissue targeting specificity of BMV-PD-1,laying the groundwork for further development of BMV-PD-1 as a carrier for targeted drug delivery systems in tumors.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To evaluate the outcomes of stroke treatment in neurology and rehabilitation departments using the International Classification of Functioning, Disability and Health′s Rehabilitation Set (ICF-RS).Method:The functional status of stroke survivors before and after treatment in the neurology and rehabilitation departments was evaluated using the ICF-RS (30 items). Each patient′s functioning was graded (normal, mild, moderate or severe dysfunction) by an experienced clinical evaluator and also by the intelligent evaluation model in the ICF-RS app. Medical expenditure data during hospitalization were extracted from the hospital′s case records. Rank sum tests compared the functional changes in a patient before and after their rehabilitation. Kappa coefficients were computed to evaluate the consistency of the functional grades assigned by the evaluators and the app.Results:Before the rehabilitation treatment, all 30 items of the ICF-RS were abnormal for all of the patients from the neurology and rehabilitation departments. After their rehabilitation treatment, 25 items had improved significantly for the neurology patients and 8 had improved significantly for those from the rehabilitation department. After their rehabilitation treatment, the average functional improvement among the neurology patients was 25%. For the rehabilitation patients it was 13%. The total expenditure for every 1% improvement in function was Y977 for the neurology patients (including Y143 for rehabilitation) and Y1, 481 for the rehabilitation patients (including Y862 of actual rehabilitation). The proportions of rehabilitation expenditure were thus 14% and 58% respectively. The kappa coefficients quantifying overall consistency were both greater than 0.8.Conclusion:The national standard ICF-RS can be used to evaluate functional changes, rehabilitation efficacy and the composition of stroke patients′ medical expenditures in the early stage of neurology and the recovery period in the rehabilitation department. The consistency of the functional level evaluations between the app and human evaluators is good.
