Objective To find out whether photobiomodulation(PBM)can mitigate cognitive dysfunction caused by chronic stress by affecting levels of adenosine triphosphate(ATP)and adenosine receptors.Methods Twenty-four C57BL/6J mice were randomly divided into a control group,a stress group,and a treatment group.Chronic unpredictable mild stress was used to establish a mouse model of stress.Six weeks into modeling,the treatment group was subjected to one week of PBM interventions.Behavioral tests were conducted to observe behavioral changes in the mice.Western blotting(WB)was used to detect the expressions of A1,A2B,and A3 adenosine receptors in the hippocampus and prefrontal cortex of mice in the three groups.Twelve C57BL/6J mice were randomly divided into a control group and an intervention group.The intervention group received a week of PBM interventions and underwent behavioral testing.WB was used to detect the expression changes of A1,A2B,and A3 adenosine receptors in the hippocampus and prefrontal cortex in both groups.Immunofluorescence assay was adopted to detect the expression of c-Fos in the hippocampus of mice in the two groups.The ATP assay kit made by Beyotime Biotechnology Co.,Ltd.was used to measure changes in ATP contents in the hippocampus and prefrontal cortex tissues of mice.Cell experiments were conducted to verify the effect of PBM on intracellular ATP contents.Results Mice in the stress group covered a similar distance to the control group,but finished far fewer platform crossings.There was no significant difference between the treatment group and the control group in the number of times of platform crossings,but compared favorably with the stress group where the levels of adenosine receptors in the hippocampus and prefrontal cortex were lower,but were increased by PBM.After PBM interventions in normal mice,platform crossings were increased significantly compared to the control group.PBM also raised adenosine receptor levels and ATP contents in the hippocampus and prefrontal cortex,and increased hippocampal c-Fos expressions.In vitro,PBM elevated intracellular ATP levels.Conclusion PBM may improve chronic stress-induced cognitive dysfunction by regulating ATP levels and adenosine receptor expressions,thereby modulating neuronal responsiveness in the hippocampus.

Foodborne illnesses caused by Salmonella pose significant threats to worldwide public health safety.In this study,a rapid method for screening viable Salmonella in oyster sauce and milk was developed by utilizing an electronic microbial growth analyzer(EMGA).Target food samples were diluted 10-fold with RVS broth and loaded into test tubes.Test tubes were positioned in the EMGA to determine the bacterial growth curves and the time required to reach the maximum growth rate(Tmgr).Using Salmonella typhimurium(S.typhimurium)asan model species,there was linear relationship between the logarithmic value of viable bacterial concentration(lgC)and Tmgr over the range of 5×101-5×106 CFU/mL,with a detection limit of 10 CFU/mL.For oyster sauce,the regression equation was Tmgr(min)=-80.775lg[C/(CFU/mL)]+754.96(R2=0.9907),and the recovery rates of S.typhimurium ranged from 95.2%to 119.8%,with relative standard deviations(RSD)ranging from 3.5%to 16.3%.For milk,the regression equation was Tmgr(min)=-71.922 lg[C/(CFU/mL)]+618.65(R2=0.9985),with recovery rates ranging from 98.4%to 110.6%and RSD ranging from 6.4%to 12.8%.The EMGA method required only one portable instrument,and involving only three manual steps,i.e.,dilution,transfer,and insertion.When S.typhimurium contamination reached 106 CFU/mL,the total time consumption,from the unwrapping of samples to the readout of bacterial concentration,was no more than 7 h.When applied to detection of actual oyster sauce and milk samples,the new method demonstrated strong consistency with plate counting results in positive detection rates.This method was superior to the plate counting method,which was generally considered as a gold standard,in terms of accuracy,precision,simplicity and efficiency,representing a promising alternative for the on-site screening and quantification of viable Salmonella in oyster sauce and milk products.

Objective:To evaluate the efficacy and safety of baricitinib combined with ruxolitinib cream in the treatment of progressive nonsegmental vitiligo.Methods:Clinical data were retrospectively collected from patients with progressive nonsegmental vitiligo in Boao Super Hospital. All the patients were treated with oral baricitinib daily (2 mg/day for patients weighing ≤ 50 kg; 4 mg/day for those > 50 kg) in combination with topical application of ruxolitinib cream twice daily for 24 consecutive weeks. Disease severity was assessed using the facial vitiligo area scoring index (F-VASI) and total body VASI (T-VASI) at baseline, week 12, and week 24. Adverse reactions were monitored throughout the treatment course.Results:Six patients with progressive nonsegmental vitiligo were collected, including 3 males and 3 females, aged 26 - 42 years, with the disease duration ranging from 0.5 to 25 years. At week 12, 3 patients achieved a 50% ~ < 75% improvement in facial vitiligo lesions (F-VASI 50), 1 patient achieved F-VASI 75 (75% ~ < 90% improvement), and 1 patient achieved T-VASI 50; at week 24, 4 patients achieved F-VASI 50, 1 patient achieved F-VASI 75, 1 patient achieved F-VASI 90 (≥ 90% improvement), and 3 patients achieved T-VASI 50. During the treatment, upper respiratory infection occurred in 1 patient, acne in 1 patient, pruritus in 2 patients, elevation of total cholesterol levels in 2 patients, and increase of high-density lipoprotein levels in 2 patients. No severe adverse events were observed during the treatment.Conclusion:The combination therapy with baricitinib and ruxolitinib cream may have potential efficacy and safety in the treatment of progressive nonsegmental vitiligo.

OBJECTIVE: Paridis Rhizoma (Chonglou in Chinese), a traditional Chinese herbal medicine, has been shown have strong anti-tumor effects. Paris saponin VII (PSVII), an active constituent isolated from Paridis Rhizoma, was demonstrated to significantly suppress the proliferation of BxPC-3 cells in our previous study. Here, we aimed to elucidate the anti-pancreatic ductal adenocarcinoma (PDAC) effect of PSVII and the underlying mechanism. METHODS: Cell viability was determined by CCK-8, colony formation, and cell migration assays. Cell apoptosis and reactive oxygen species (ROS) production were measured by flow cytometry with annexin V/propidine iodide (Annexin V/PI) and 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA), respectively. Pyroptosis was evaluated by morphological features, Hoechst 33342/PI staining assay, and release of lactate dehydrogenase (LDH). JC-1 fluorescent dye was employed to measure mitochondrial membrane potential. Western blotting and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) were used to determine the levels of proteins or mRNAs. The effect in vivo was assessed by a xenograft tumor model. RESULTS: PSVII inhibited the viability of PDAC cells (BxPC-3, PANC-1, and Capan-2 cells) and induced gasdermin E (GSDME) cleavage, as well as the simultaneous cleavage of Caspase-3 and poly (ADP-ribose) polymerase 1 (PARP). Knockdown of GSDME shifted PSVII-induced pyroptosis to apoptosis. Additionally, the effect of PSVII was significantly attenuated by Z-Asp(OMe)-Glu(OMe)-Val-Asp(OMe)-fluoromethylketone (Z-DEVD-FMK), on the induction of GSDME-dependent pyroptosis. PSVII also elevated intracellular ROS accumulation and stimulated Bax and Caspase-3/GSDME to conduct pyroptosis in PDAC cells. The ROS scavenger N-acetyl cysteine (NAC) suppressed the release of LDH and inhibited Caspase-9, Caspase-3, and GSDME cleavage in PDAC cells, ultimately reversing PSVII-induced pyroptosis. Furthermore, in a xenograft tumor model, PSVII markedly suppressed the growth of PDAC tumors and induced pyroptosis. CONCLUSION These results demonstrated that PSVII exerts therapeutic effects through Caspase-3/GSDME-dependent pyroptosis and may constitute a novel strategy for preventing chemotherapeutic resistance in patients with PDAC in the future.

OBJECTIVE: To assess health equity in the Yangtze River region to improve understanding of the correlation between hand, foot, and mouth disease (HFMD) and socioeconomic factors. METHODS: From 2014-2016, data on HFMD incidence, population statistics, economic indicators, and meteorology from 26 cities along the Yangtze River were analyzed. A multi-city random-effects meta-analysis was performed to study the relationship between temperature and HFMD transmission, and health equity was assessed with respect to socio-economic impact. RESULTS: Over the study period, 919,458 HFMD cases were reported, with Shanghai (162,303) having the highest incidence and Tongling (5,513) having the lowest. Males were more commonly affected (male-to-female ratio, 1.49:1). The exposure-response relationship had an M-shaped curve, with two HFMD peaks occurring at 4 °C and 26 °C. The relative risk had two peaks at 1.30 °C (1.834, 95% CI: 1.204-2.794) and 31.4 °C (1.143, 95% CI: 0.901-1.451), forming an M shape, with the first peak higher than the second. The most significant impact of temperature on HFMD was observed between -2 °C and 18.1 °C. The concentration index (0.2463) indicated moderate concentration differences, whereas the Theil index (0.0418) showed low inequality in distribution. CONCLUSION The incidence of HFMD varied across cities, particularly with changes in temperature. Economically prosperous areas showed higher risks, indicating disparities. Targeted interventions in these areas are crucial for mitigating the risk of HFMD.

Objective:To systematically summarize, describe, and evaluate the evidence related to convex baseplates use in adult ostomy patients through an evidence map, in order to identify research gaps and future directions.Methods:A systematic search was conducted in Chinese and English databases, including China National Knowledge Infrastructure, Wanfang Data, VIP, and PubMed, and others, from database inception to September 2024. Randomized controlled trials and quasi-experimental studies on convex baseplates use in adult ostomy patients were included. Literature quality was assessed using the Cochrane Handbook 5.1.0 bias risk assessment tool and the critical appraisal tool for quasi-experimental studies from the Joanna Briggs Institute Centre for Evidence-Based Healthcare. Based on the PICO principle [participant (P) , intervention (I) , comparison (C) , outcome (O) ] , an evidence mapping coding system was extracted and developed by integrating relevant guidelines and consensus. Data extraction and coding were performed using EPPI-Reviewer software, and key evidence characteristics and literature quality were presented using bubble charts.Results:A total of eight randomized controlled trials and six quasi-experimental studies were included. Most of the 14 studies had a high risk of bias. The target populations for interventions were divided into two categories: prevention and treatment. The main complications involved stoma skin-mucosal separation, stoma peristomal dermatitis, and stoma height issues. The main outcome measures included baseplate seal integrity, wound healing, complication rates, clinical symptoms, adverse events, patient acceptance, and quality of life.Conclusions:Most of the studies on convex baseplates has focused on enterostomy patients. The majority of studies have a high risk of bias, and the number of studies is limited. Further clarification is needed on the selection criteria for convex baseplates with different characteristics, and the clinical application effects of convex baseplates urgently need further evaluation.

Objective:To explore the difficulties and needs of wound ostomy incontinence specialist nurses when applying convex baseplates, with the aim of providing a basis for standardizing ostomy care.Methods:Purposeful sampling was used to select 13 wound ostomy incontinence specialist nurses from tertiary hospitals in Hebei, Jilin, Hunan, Beijing, and Tianjin for semi-structured interviews between November and December 2024. Content analysis was used to analyze the data.Results:Two main themes were identified: application dilemmas and application needs. Application dilemmas included four subthemes: insufficient understanding of convex baseplate characteristics, unclear indications and contraindicated populations, lack of unified standards for assessment timing, and inadequate awareness of health education. Application needs included two subthemes: urgent need for related evidence-based evidence and a desire for clinical guidelines and expert consensus.Conclusions:Currently, wound ostomy incontinence specialist nurses in China face challenges in understanding the characteristics of convex baseplates, scope of application, identifying contraindications, determining the optimal timing for application assessment, and providing patient education. Administrators should develop clinical application standards for convex baseplates based on these challenges. Furthermore, researchers should develop relevant clinical guidelines or expert consensus for convex baseplate application in China, providing a basis for the standardized use of ostomy care products.

Objective:To evaluate the role of tumor necrosis factor-α-induced protein 8-like molecule-2 (TIPE2) in the endogenous protective mechanism against acute lung injury in septic mice and the relationship with ferroptosis.Methods:Twenty SPF healthy wild-type male C57BL/6N mice and 20 TIPE2 gene knockout C57BL/6N mice, aged 6-8 weeks, weighing 20-25 g, were assigned to wild-type sham operation group (WT-Sham group), wild-type sepsis group (WT-SEP group), TIPE2 knockout sham operation group (KO-Sham group), and TIPE2 knockout sepsis group (KO-SEP group) using a random number table method, with 10 mice in each group. Acute lung injury was induced by cecal ligation and perforation in anesthetized mice. The animals were sacrificed after anesthesia at 24 h after operation and lung tissues were obtained for examination of the morphological results of lung tissues (with a light microscope) and for determination of wet to dry lung weight (W/D) ratio, contents of ferrous ions (Fe 2+ ), glutathione (GSH) and malondialdehyde (MDA) and expression of solute carrier family 7 member 11 (SLC7A11), glutathione peroxidase 4 (GPX4) and Acyl-CoA synthetase long-chain family member 4 (ACSL4) (by Western blot). Results:Compared with WT-Sham group, the lung injury score, W/D ratio and contents of Fe 2+ and MDA were significantly increased, the content of GSH was decreased, the expression of GPX4 and SLC7A11 was down-regulated, and the expression of ACSL4 was up-regulated in WT-SEP group ( P<0.05). Compared with WT-SEP group, the lung injury score, W/D ratio and contents of Fe 2+ and MDA were significantly increased, the content of GSH was decreased, the expression of GPX4 and SLC7A11 was down-regulated, and the expression of ACSL4 was up-regulated in KO-SEP group ( P<0.05). Conclusions:TIPE2 is involved in the endogenous protective mechanism against acute lung injury, which may be related to the inhibition of ferroptosis in lung tissues of septic mice.

The scaphoid bone is one of the important bone of hand,which is frequently injured and difficult to treat in clinical practice.Therefore,it is very important to deeply study the microstructure and biomechanical characteristics of the scaphoid bone for understanding its injury mechanism and optimizing treatment scheme.Microcomputed tomography(micro-CT)provides high-resolution imaging of bone tissue,while finite element analysis can help to simulate the stress distribution and behavioral patterns of the scaphoid bone under various physiological and pathological states.The high-resolution three-dimensional image of the scaphoid bone obtained by micro-CT technology can be used to construct finite element models of real anatomical structure of the scaphoid bone,thus achieving accurate simulation of the mechanical properties of the scaphoid bone.The fusion of these two advanced technologies provides a new perspective for revealing the structural and functional relationships and injury mechanism of the scaphoid bone.Therefore,this paper reviews the anatomical characteristics of the scaphoid bone and its biomechanical behavior in different states,emphasizing the specific applications and advantages of micro-CT and finite element analysis techniques in the study of the scaphoid bone.By summarizing the research findings in recent years,this paper provides novel scientific basis and methods for the diagnosis,treatment,and prevention of scaphoid bone-related disorders.
