Objective: To explore the application effectiveness of healthcare failure mode and effect analysis (HFMEA) in optimizing intelligent blood logistics transport pathways for safety assurance. Methods: Data from 1 851 cases of intelligent blood logistics transport were collected between September 2023 and March 2025. Based on the implementation phases of HFMEA measures, the cases were divided into a control group (n=120), observation group 1 (n=219), and observation group 2 (n=1 512). Through systematic analysis of the transport processes, hazard scoring and decision tree analysis were conducted for each process, and phased optimization measures were implemented for high-risk failure modes. Results: The transport duration of intelligent blood logistics was 35.5 (20.8, 71.1) min in the control group, 25.1 (10.9, 40.7) min in observation group 1, and 9.9 (4.2, 44.5) min in observation group 2. Observation group 2 exhibited significantly shorter transport time compared to both observation group 1 and the control group, with statistically significant differences between groups (P<0.000 1). Conclusion: The implementation of HFMEA-driven measures significantly reduced intelligent blood logistics transport duration, thereby fostering the evolution of smart hospital ecosystems while enhancing healthcare service quality and operational efficiency.

BACKGROUND/OBJECTIVES: Unhealthy diets are associated with chronic stress. An allostatic load (AL) is a comprehensive physiological index that measures the chronic stress response of the body. As a healthy dietary pattern, the role of Dietary Approaches to Stop Hypertension (DASH) in the development of an AL during pregnancy remains unclear. This study examined the relationship between the DASH dietary pattern and AL during pregnancy. SUBJECTS/METHODS: This study was a prospective study. From January 2024 to November 2024, 134 pregnant women in the second trimester (23–27 weeks) and third trimester (32–36 weeks) of pregnancy who met the inclusion and exclusion criteria in the obstetrics clinic of a tertiary general hospital in Anhui Province were selected for a questionnaire survey, physical examination, and laboratory examination. The DASH dietary pattern was assessed using the DASH scoring tool, and the total AL score was calculated using nine biomarkers that represent the cardiovascular, metabolic, and immune systems. Logistic regression was used to analyze the relationship between the DASH score and AL. RESULTS: One hundred and thirty-four pregnant women were included in this study. At the second and third trimesters, 41.8% and 37% of pregnant women, respectively, were in the high AL group. The binary logistic regression results showed that the DASH score was negatively correlated with the AL in the unadjusted model (odds ratio [OR], 0.878; 95% confidence interval [CI], 0.807–0.957; P = 0.003) and adjusted model (OR, 0.878; 95% CI, 0.792–0.973; P = 0.013) in the second trimester, the DASH score was negatively correlated with the AL in the unadjusted model (OR, 0.832; 95% CI, 0.758–0.913; P < 0.001) and adjusted model (OR, 0.806; 95% CI, 0.716–0.908; P < 0.001) in the third trimester. CONCLUSION The DASH score was negatively correlated with the AL in pregnant women.A low DASH score may increase the risk of a high AL, which may have adverse effects on physical and mental health.

Apical microsurgery is accurate and minimally invasive, produces few complications, and has a success rate of more than 90%. However, due to the lack of awareness and understanding of apical microsurgery by dental general practitioners and even endodontists, many clinical problems remain to be overcome. The consensus has gathered well-known domestic experts to hold a series of special discussions and reached the consensus. This document specifies the indications, contraindications, preoperative preparations, operational procedures, complication prevention measures, and efficacy evaluation of apical microsurgery and is applicable to dentists who perform apical microsurgery after systematic training.

ObjectiveTo improve the accuracy of discrete element method in simulating the processing of traditional Chinese medicine（TCM） powder system under low shear conditions. MethodsIn this study， extract powders of Tongsaimai tablets and Qige granules were used as the research objects， the angle of repose（AOR） and effective angle of internal friction of the two materials were determined by AOR test method and shear cell test method. Based on the Hertz-Mindlin with JKR V2 contact model and particle scaling theory， taking the particle-particle restitution coefficient（A）， particle-particle static friction coefficient（B）， particle-particle rolling friction coefficient（C）， particle-steel restitution coefficient（D）， particle-steel static friction coefficient（E）， particle-steel rolling friction coefficient（F） and Johnson-Kendall-Roberts（JKR） surface energy（G） as test factors， the simulated contact parameters of Tongsaimai tablets extract powder were first calibrated with a single reference value using AOR as the reference value， and then the simulated contact parameters of Tongsaimai tablets extract powder as well as Qige granules extract powder were co-calibrated with AOR and effective angle of internal friction as the joint reference value， respectively. Then， Plackett-Burman design was used to screen the critical contact parameters that have a significant effect on the simulated reference value， and the steepest ascent design was used to determine the optimal range of the critical contact parameters， finally， the regression model between the critical contact parameters and the simulated reference values was established through the design of the response surface test， and the critical contact parameters were calibrated based on the regression model and the desirability function approach. ResultsThe optimal combination of discrete elemental contact parameters A-G for Tongsaimai tablets extract powder under a single reference value was 0.100， 0.718， 0.616， 0.100， 0.400， 0.250 and 0.075 J·m^-2， which was validated to have relative errors of 0.10% and -8.64% for the simulated AOR and the simulated effective angle of internal friction， respectively. And the optimal combination of discrete elemental contact parameters A-G for Tongsaimai tablets extract powder at the joint reference values was 0.100， 0.682， 0.598， 0.100， 0.521， 0.294 and 0.075 J·m^-2， which was verified to have relative errors of 0.10% and -0.18% for the simulated AOR and the simulated effective angle of internal friction， respectively. The optimal combination of discrete elemental contact parameters A-G for Qige granules extract powder at the joint reference values was 0.150， 0.370， 0.330， 0.150， 0.500， 0.500 and 0.100 J·m^-2， which was verified to have relative errors of 2.70% and -1.30% for the simulated AOR and the simulated effective angle of internal friction， respectively. Compared with the single reference value method， the joint calibration method not only increased the number of the critical contact parameters for characterizing particle-device interactions， but also was more accurate and reliable. ConclusionCompared with the results of single reference value calibration， the results obtained by the method of joint calibration of discrete element simulation contact parameters with AOR and effective angle of internal friction as the reference values are more accurate， which can provide more accurate and reliable simulation physical property data for the simulation experiments of TCM extract powder under low shear process conditions.

AIM: To evaluate the safety and efficacy of allogeneic intrastromal lenticule implantation combined with corneal collagen cross-linking(CXL)in patients with moderate to advanced keratoconus.METHODS: A retrospective case series analysis was conducted. A total of 19 patients(20 eyes)with moderate to advanced keratoconus who underwent combined allogeneic intrastromal lenticule implantation and CXL at the Jinan Mingshui Eye Hospital from June 2021 to December 2023 were included. The uncorrected distance visual acuity(UCVA), thinnest corneal thickness, central corneal epithelial thickness, anterior corneal flat keratometry(Kf), steep keratometry(Ks), and mean keratometry(Km), as well as the first applanation time(A1T), the first applanation length(A1L), the velocity during the first applanation moment(VIN), the second applanation time(A2T), the second applanation length(A2L), the velocity during the second applanation moment(VOUT), highest concavity time(HCT), highest concavity radius(HCR), peak distance(PD), deformation amplitude(DA), stiffness parameter at first applanation(SP-A1), integrated radius(IR), central corneal thickness(CCT), intraocular pressure(IOP), corneal thickness-corrected IOP, biomechanically intraocular pressure IOP(bIOP), and corneal thickness variation rate(ARTH)were compared between the two groups before surgery and at 1 wk, 1, 3 and 6 mo after surgery.RESULTS: All patients successfully completed the surgery without any intraoperative complications. No significant differences were observed between pre-operative and post-operative measurements for UCVA or the corneal biomechanical parameters, including A1L, A2L, PD, A1T, A2T, VIN, VOUT, DA, IOP, and bIOP(all P>0.05). Significant differences were found between pre-operative and post-operative values for corneal thinnest point thickness, central corneal epithelial thickness, Kf, Ks, Km, and the corneal biomechanical parameters, including HCT, HCR, SP-A1, ARTH, IR, and CCT(all P<0.05). The anterior corneal curvature demonstrated an initial increase followed by a decrease post-operatively. Furthermore, significant differences were observed between pre-operative and post-operative values for HCT, HCR, SP-A1, ARTH, IR, and CCT(all P<0.005).CONCLUSION: Allogenic intrastromal lenticule implantation combined with corneal collagen cross-linking demonstrates favorable safety and stability in treating moderate-to-advanced keratoconus. This combined procedure effectively increases corneal thickness and rigidity, resulting in corneas that are more resistant to deformation postoperatively.

OBJECTIVE To explore the effect and potential mechanisms of berberine on formation of biofilms of clinical methicillin-resistant Staphylococcus aureus(MRSA)isolates.METHODS Totally 95 clinical MRSA iso-lates were collected from Shanghai Eighth People's Hospital from Jan.2023 to Dec.2023.The 14 biofilm forma-tion-related genes in the strains were detected by polymerase chain reaction(PCR)and multiplex PCR,the mini-mum inhibitory concentration(MIC)of berberine was determined by microbroth dilution method,the effect of berberine on resistance of biofilm formation was evaluated by crustal violet staining,fluorescence microscope,Congo red agar plate and extracelluar DNA(eDNA).The transcription levels of 9 biofilm formation-related genes were detected by real-time fluorescent quantitative reverse transcription PCR.RESULTS All of the 95 strains of MRSA carried eno,clfA,clfB and icaA genes,the most widespread gene profile was bbp-eno-ebpS-fnbA-fib-clfA-clfB-icaA-sasG,and 29 strains had the phenotypes with strong capability of biofilm formation.The MIC score of berberine ranged between 64 and 1 024 μg/ml.Berberine with the concentration of 1/2 MIC could inhibit the biofilm formation of MRSA(P＜0.001),and the inhibiting rate of biofilm formation of the MIC ≥512 μg/ml group was higher than that of the MIC≤128 μg/ml group and the MIC 256 μg/ml group(all P＜0.05).The re-sult under the fluorescence microscope showed that the fluorescence intensity of biofilms decreased with the rise of berberine concentration.Berberine could reduce the formation of amyloid fibrils and the release of eDNA,down-regulating the transcription levels of ica A,sasG,ebpS,fib,eno,clfA,clfB,bbp and fnbA genes(P＜0.05).CONCLUSION Berberine may inhibit the biofilm formation of MRSA by downregulating expression levels of related genes,interfering the formation of amyloid fibrils and blocking the release of eDNA,which may provide experimental bases for development of drugs resisting to MRSA biofilms.

Malignant tumors (commonly referred to as cancer) represent a major global public health challenge and contribute significantly to the worldwide disease burden. Early screening plays a critical role in improving detection rates, enabling timely intervention, and enhancing patient survival rates. However, current cancer screening guidelines primarily focus on site-specific screening, which may not fully address the need for comprehensive early detection. A scientifically rational, multi-cancer screening approach offers several advantages: it optimizes the use of biological samples, reduces time costs for participants, enhances the efficiency and comprehensiveness of screening, and minimizes overall expenses. Such an approach also facilitates the rational allocation of healthcare resources, ultimately helping to reduce the societal burden of cancer. To address this need, the Cancer Epidemiology Committee of the Chinese Anti-Cancer Association has developed the Expert Consensus on Combined Screening for Common Cancers in China. This consensus integrates multidisciplinary expertise and synthesizes the latest domestic and international researches on cancer screening, early detection, and treatment for prevalent malignancies. Drawing upon China's unique demographic and healthcare context, as well as practical screening experiences, the consensus provides evidence-based recommendations on target populations, screening technologies, and procedural workflows for multi-cancer screening. These guidelines align with the principles and methodologies established by the World Health Organization (WHO), aiming to enhance the effectiveness of combined cancer screening in China, improve early detection rates, and provide a scientific foundation for national cancer prevention and control strategies.

Objective:To observe the short-term and medium-term clinical effects of electroacupuncture(EA)on patients with lumbar disc herniation(LDH)and to explore the cerebral effects based on resting-state functional magnet-ic resonance(rs-fMRI).Method:Thirty patients with LDH received EA at bilateral L3—S1 jiaji(EX-B2)and Dachangshu(BL25)points in continuous-wave mode at 20Hz(intensity adjusted to patient tolerance),20 minutes per session,every other day for ten sessions.Thirty-three age-and sex-matched healthy volunteers served as controls.All patients underwent rs-fMRI scans before treatment;The LDH group was rescanned one month after completion of EA.The modified Oswestry disability index(ODI),mental health summary(MCS)and physical health summary(PCS)of the short form health survey(SF-36)were assessed in LDH group before treatment and one,three,and six months after treatment.Voxel-wise regional homogeneity(ReHo)and degree centrality(DC)in brain areas were computed to compare between the two groups at baseline and pre-and post-treatment in LDH group.Result:After EA,LDH patients experienced significant reductions in ODI scores at one,three,and six months compared with baseline(P<0.05).PCS score continued to significantly improve at 3 months and 1 month(P<0.05),and the efficacy was the best at 3 months.There was a downward trend in 6 months after treatment,but still remained above baseline(P=0.072).The MCS score also rose at one and three months(P<0.05)but declined by six months.Compared with the control group,LDH patients exhibited increased ReHo in the left anterior cingulate gyrus,elevated DC in bilateral thalami,and decreased DC in bilateral postcentral gyri.After EA treatment,the LDH group showed increased ReHo in bilateral precuneus and the right middle frontal gyrus,as well as increased DC in the left postcentral gyrus.Conclusion:Electroacupuncture improves the short-term and medium-term clinical outcomes in LDH patients,with maximal benefit at three months.The role of electroacupuncture in improving pain and mental health is related to the regulation of pain matrix,default mode brain network,and emotional cognitive control network.

Objective:To explore the relationship between depression, perfectionism and self-injurious function in adolescents with self-injury.Methods:A total of 6 149 adolescents from two middle schools were selected by multi-stage random sampling method to conduct a cross-sectional investigation, and 530 cases with self-injurious behaviors were screened out as the self-injury group, while the remaining 5 619 students served as the non-self-injury group.The self-rating depression scale, the Chinese-revised Frost multidimensional perfectionism scale, and the Ottawa self-injury inventory Chinese revised version were used for investigation.SPSS 24.0 software was used for descriptive statistics and Spearman correlation analysis, and the PROCESS 4.1 macro program was used for mediating effect test(model 4)and moderating effect test(model 7).Results:(1)The incidence of self-injury among adolescents was 8.62%(530/6 149), which was significantly different in gender( χ2=50.942, P<0.01) and grade( χ2=37.401, P<0.01). (2)The scores of depression(48(41, 55)) and maladaptive perfectionism(64(53, 76)) in the self-injury group were higher than those in the non-self-injury group(36(29, 43), 49(35, 61)), and the differences were statistically significant( Z=-23.233, -18.599, both P<0.01). (3)Adolescents with self-injury mostly had external emotion regulation(70.38%(373/530)) as the dominant function.(4)The results of Spearman correlation analysis showed that self-injurious function was significantly and positively correlated with depression( r=0.382, P<0.01) and maladaptive perfectionism( r=0.356, P<0.01), and depression was significantly and positively correlated with maladaptive perfectionism( r=0.352, P<0.01). (5)Maladaptive perfectionism partially mediated the relationship between depression and self-injurious function( β=0.086, P<0.001), and the mediating effect accounted for 21.88%(0.086/0.393)of the total effect.(6)Gender moderated the first stage of the mediation pathway(depression→maladaptive perfectionism)( β=0.180, P<0.05), which indicated that depression had a stronger predictive effect on maladaptive perfectionism in women( βsimple=0.105, 95% CI=0.063-0.154, P<0.05). Conclusion:In the prediction of depression on self-injurious function, maladaptive perfectionism plays a partial mediating role, and this mediating effect is moderated by gender.
