Hepatitis B virus （HBV） infection is a global public health issue， affecting the health of 250 million people worldwide. Despite the significant progress in antiviral therapy for HBV， some patients still experience low-level viremia （LLV） after receiving antiviral therapy and fail to achieve viral clearance， with an HBV DNA load remaining at a relatively low level of 20 — 2 000 IU/mL. LLV is often caused by multiple factors such as the high stability of the virus， the difficulty in clearing the virus with antiviral drugs， host immune factors， and drug resistance， which increase the difficulties in antiviral therapy. In addition， LLV can also cause liver damage， which may eventually progress to severe outcomes such as hepatocellular carcinoma. This article reviews LLV in hepatitis B in terms of diagnosis， influencing factors， clinical significance， and treatment strategies.

Objective:To evaluate the role of nuclear factor E2-related factor 2 (Nrf2)/heme oxygenase (HO-1) signaling pathway in the attenuation of endotoxin-induced acute lung injury (ALI) by hydromorphone and the relationship with Golgi apparatus stress (GA stress) in mice.Methods:Eighteen SPF wild-type (WT) and 18 Nrf2 knockout (Nrf2 KO) male C57BL/6J mice, aged 6-8 weeks, weighing 18-20 g, were divided into 3 groups ( n=6 each) using a random number table method: control groups (WT+ Con group, Nrf2 KO+ Con group), ALI groups (WT+ ALI group, Nrf2 KO+ ALI group) and ALI+ hydromorphone groups (WT+ ALI+ HM group, Nrf2 KO+ ALI+ HM group). ALI was induced by injecting lipopolysaccharide (LPS) 15 mg/kg via the tail vein in anesthetized animals. Hydromorphone 120 μg was intraperitoneally injected at 15 min before LPS injection in WT+ ALI+ HM group and Nrf2 KO+ ALI+ HM group, and the equal volume of normal saline was given instead in control groups. The animals were sacrificed after anesthesia at 12 h after LPS injection, and lung tissues were obtained for examination of the pathological changes which were scored and Golgi ultrastructure (with a transmission electron microscope) and for determination of the content of malondialdehyde (MDA), activity of superoxide dismutase (SOD), and expression of Nrf2, HO-1 and Golgi stress-related markers (Golgi matrix protein 130 [GM130], Golgi autoantigen 97 kDa [Golgin-97], ATPase secretory pathway Ca 2+ Transporting 1 [ATP2C1], Golgi phosphoprotein 3 [GOLPH3]) (by Western blot). Results:Compared with WT+ Con group and Nrf2 KO+ Con group, the lung injury scores and content of MDA were significantly increased, the activity of SOD was decreased, the expression of GM130, Golgin-97 and ATP2C1 was down-regulated, the expression of GOLPH3 was up-regulated ( P<0.05), no significant changes were found in the expression of Nrf2 and HO-1 ( P>0.05), and the damage to the Golgi apparatus was aggravated in WT+ ALI group and Nrf2 KO+ ALI group. Compared with WT+ ALI group, the lung injury scores and content of MDA were significantly decreased, the activity of SOD was increased, the expression of Nrf2, HO-1, GM130, Golgin-97 and ATP2C1 was up-regulated, the expression of GOLPH3 was down-regulated ( P<0.05), and the damage to the Golgi apparatus was significantly attenuated in WT+ ALI+ HM group. Compared with Nrf2 KO+ ALI group, the lung injury scores were significantly decreased, and the activity of SOD was increased ( P<0.05), no significant changes were found in the content of MDA and expression of Nrf2, HO-1, GM130, Golgin-97, ATP2C1 and GOLPH3 ( P>0.05), and no significant reduction in the damage to the Golgi apparatus was found in Nrf2 KO+ ALI+ HM group. Compared with WT+ ALI+ HM group, the lung injury scores and content of MDA were significantly increased, the activity of SOD was decreased, the expression of Nrf2, HO-1, GM130, Golgin-97 and ATP2C1 was down-regulated, the expression of GOLPH3 was up-regulated ( P<0.05), and the damage to the Golgi apparatus was aggravated in Nrf2 KO+ ALI+ HM group. Conclusions:Nrf2/HO-1 signaling pathway is involved in the attenuation of endotoxin-induced ALI by hydromorphone, and it is associated with the inhibition of Golgi stress.

Objective:To investigate the differences in resistance to chemical disinfectants between bacteriophage Phi-X174 and disinfection effect indicator microorganisms, Staphylococcus aureus and Escherichia coli. Methods:Three commonly used disinfectants, including chlorine-containing disinfectants, alcohol-based disinfectants and quaternary ammonium salt disinfectants, were selected to analyze the differences in resistance of phage Phi-X174, Staphylococcus aureus and Escherichia coli by using the quantitative sterilization test of suspension. Results:The 250 mg/L sodium dichloroisocyanurate solution treated for 10 minutes yielded log reduction values of 3.39, 7.25 and 7.37 against phage Phi-X174, Staphylococcus aureus and Escherichia coli respectively. The 40% ethanol for 1 minute yielded log reduction values of 0.03, 2.46 and 7.30 against phage Phi-X174, Staphylococcus aureus and Escherichia coli, respectively. The 100 mg/L benzalkonium chloride for 10 minutes yielded log reduction values of 1.41, 6.84 and 0.93 for phage Phi-X174, Staphylococcus aureus and Escherichia coli, respectively. Conclusion:Phage Phi-X174 has stronger resistance to chlorine-containing disinfectants and alcohol-based disinfectants than Escherichia coli and Staphylococcus aureus. Its resistance to quaternary ammonium salt disinfectants is between that of Staphylococcus aureus and Escherichia coli.

Objective To explore the effect of organizational climate on work alienation in psychiatric nurses,and the mediating role of psychological capital and positive coping styles between organizational climate and work alienation,in order to provide a reference for reducing work alienation among psychiatric nurses.Methods Convenience sampling method was used to select nurses working in 6 tertiary A psychiatric hospitals in Shandong Province from January to July 2024,and the general questionnaire,Nurses' Work Alienation Questionnaire,Organizational Climate Scale for Nursing,Psychological Capital Questionnaire,and Simple Coping Style Scale were used to conduct the survey and the mediation effect test.Results A total of 606 questionnaires were recovered,of which 572 were valid,and the validity rate of the questionnaires was 94.39％.Psychiatric nurses scored(89.58±13.69)for nursing organizational climate,(32.48±11.31)for work alienation,(97.28±19.12)for psychological capital,and(23.93±7.22)for positive coping styles.There was a direct effect of nursing organizational climate on work alienation(β=-0.681,95％CI=-0.824～-0.539).Psychological capital and positive coping styles acted as separate mediators and chain mediators in the effect of nursing organizational climate on work alienation(β=-0.116,-0.048,-0.019,95％CI=-0.182～-0.034,-0.086～-0.006,-0.042～-0.002).Conclusion There are multiple mediating effects of psychiatric nurses' psychological capital,positive coping styles between nursing organizational climate and work alienation.Nursing managers can enhance psychiatric nurses' psychological capital by creating a positive and healthy organizational climate,encouraging them to adopt positive coping styles to solve problems,and reducing work alienation.

This study aims to establish an indirect ELISA method for detecting RVFV antibodies u-sing recombinant proteins of Rift Valley fever virus(RVFV)Gn protein Ⅱ-Ⅲ structural domains as the encapsulated antigen which was expressed by the Escherichia coli(E.coli)expression sys-tem.The gene sequences encoding the Ⅱ and Ⅲ subdomains of RVFV Gn protein were inserted in-to pET-30a(+)to construct the recombinant plasmid pET-RVFV Gn-D Ⅱ-Ⅲ.After transforma-tion of the recombinant plasmid into DE3(BL21)competent cells,the recombinant Gn-D Ⅱ-Ⅲ protein was induced with IPTG and purified using affinity chromatography.An indirect ELISA method for the detection of RVFV antibodies was developed using purified recombinant protein as coating antigen and SPA-HRP as the enzyme-labelled secondary antibody.Western blot analysis confirmed that the RVFV Gn-D Ⅱ-Ⅲ protein was successfully expressed.The optimal expression conditions for RVFV Gn-D Ⅱ-Ⅲ protein were induced with 0.8 mmol/L IPTG at 37 ℃ for 5 h.The Gn-D Ⅱ-Ⅲ protein was purified using affinity chromatography with a purity of 91.9％,and the purified protein was used as the encapsulated antigen to develop an ELISA assay for RVFV anti-bodies.The specificity evaluation showed that the method specifically detected RVFV-positive sera and did not cross-react with sera positive for West Nile virus(WNV),Ebola virus(EBOV),Mar-burg virus(MARV)and tick-borne encephalitis virus(TBEV).When the RVFV Gn-D Ⅲ-Ⅲ posi-tive serum was diluted to 6 400 times,the test result still showed positive results,demonstrating the method had good sensitivity.The repeatability evaluation results indicated that the variation co-efficients for both intra-and inter-batch responses was less than 10％,indicating that the method had good repeatability.In conclusion,the RVFV Gn-D Ⅱ-Ⅲ protein was successfully expressed u-sing the E.coli expression system.The purified recombinant Gn-D Ⅱ-Ⅲ protein was used as the encapsulated antigen to develop an indirect ELISA assay for RVFV antibodies,which provides a preliminary basis for the diagnosis of RVF and the research and development of RVF vaccines.

Despite primary glomerulonephritis (PGN) being a leading cause of chronic kidney disease and end-stage renal disease, specific and sensitive biomarkers for the early detection and monitoring of this condition are lacking. We evaluated the value of the combined detection of serum cystatin C (CYSC), β2-microglobulin (β2-MG), and urine transferrin (TRF) for diagnosing early-stage PGN. From May 2021 to May 2023, we enrolled 105 patients in our hospital as the observation group and 50 healthy volunteers as the control group. Their serum expression levels of CYSC, β2-MG, and TRF were evaluated. We plotted separate ROC curves and calculated the area under the curve (AUC) values of CYSC, β2-MG, and TRF to assess their diagnostic performance in PGN. The levels of CYSC, β2-MG, and TRF were significantly higher (P < 0.05) in the observation group than in the healthy control group. CYSC, β2-MG, and TRF were expressed at significantly higher levels in G2, G3a, and G3b of PGN than in G1. The combined use of CYSC, β2-MG, and TRF as biomarkers could significantly improve the early diagnosis and monitoring of PGN and may lead to better patient outcomes by facilitating earlier intervention and treatment strategies.

Objective:To investigate the correlation between cerebral blood flow (CBF) in different brain regions and gait disorder (GD) in patients with cerebral small vessel disease (CSVD).Methods:Patients with CSVD visited the Department of Neurology, the Second Affiliated Hospital of Xuzhou Medical University from November 2023 to October 2024 were included prospectively. They were divided into GD group (<0.8 m/s) and non-GD group (≥0.8 m/s) based on their step speed. CBF was measured using 3D pseudo-continuous arterial spin labeling (3D-pCASL) perfusion imaging. Gait parameters were quantitatively evaluated using a wearable gait analyzer. Multivariate logistic regression analysis was used to determine independent factors associated with GD in patients with CSVD. Partial correlation analysis was used to determine the correlation between gait parameters and CBF in different brain regions. Results:A total of 52 patients with CSVD were enrolled, including 26 males and 26 females, aged 67.00±6.84 years. Thirty-eight cases (73.1%) had mild overall burden of CSVD, and 14 cases (26.9%) had a moderate to severe overall burden of CSVD. There were 17 patients (32.7%) in the GD group and 35 (67.3%) in the non-GD group. Compared with the non-GD group, the body mass index was significantly higher, the CBF of the left occipital lobe and bilateral cerebellum decreased significantly, the step speed, step length, stride length, step frequency, swing phase, peak arm angular velocity, arm swing amplitude, maximum calf anterior/posterior swing angle, peak calf angular velocity, foot swing speed, and peak sagittal plane angular velocity in the torso decreased significantly, while the number of steps, stance phase, step length asymmetry, stride length, and step length variability increased significantly in the GD group (all P<0.05). Multivariate logistic regression analysis showed that left cerebellar CBF was an independent protective factor for GD in patients with CSVD (odds ratio 0.902, 95% confidence interval 0.827-0.982; P=0.019). For every 1 ml/(100 g.min) decreased in left cerebellar CBF, the patients with CSVD had an increased risk of developing GD by approximately 9.8%. Partial correlation analysis showed that left occipital lobe CBF was significantly positively correlated with step speed ( r=0.305, P=0.032), maximum calf back swing angle ( r=0.314, P=0.026), and peak calf angular velocity ( r=0.356, P=0.011). The left cerebellar CBF was significantly positively correlated with step speed ( r=0.295, P=0.037) and significantly negatively correlated with step length variability ( r=-0.335, P=0.017); the right cerebellar CBF was significantly positively correlated with step speed ( r=0.309, P=0.029) and significantly negatively correlated with step length variability ( r=-0.344, P=0.014). Conclusion:GD in patients with CSVD is associated with decreased CBF in the left occipital lobe and bilateral cerebellum, and decreased CBF in the left cerebellum significantly increased the risk of GD in patients with CSVD.
