Objective In this study,patients with idiopathic intracranial hypertension(IIH)were selected as a model for spaceflight-associated neuro-ocular syndrome(SANS)to conduct an eye movement manipulation intervention experiment.The aim was to explore whether eye movements have an effect on reducing the subarachnoid space around the optic nerve.Methods Twenty-three patients with IIH who met the inclusion criteria were subjected to history taking,collection of basic systemic data including age,height,weight,and blood pressure,and baseline data collection including intraocular pressure(prone)and transorbital ultrasound optic nerve sheath complex image acquisition.The subjects were then subjected to the eye movements intervention and IOP(prone)and transorbital ultrasound optic nerve sheath complex image acquisition were measured at 10 minutes,30 minutes and again 3 days after the intervention.Results The study enrolled 23 subjects with an average age of(29.58±11.25)years and a mean BMI of(28.56±6.3)kg/m2.The average cerebrospinal fluid pressure through lumbar puncture was(310.25±20.78)mmH2O.There were no significant changes in intraocular pressure at various time points before and after the eye movement exercises(P=1.000).Similarly,there were no significant changes in the diameter of the optic nerve at 3 mm and 5 mm posterior to the globe(P=1.000).However,the diameter of the optic nerve sheath at 5 mm posterior to the globe,as well as the width of the subarachnoid space of the optic nerve at 3 mm and 5 mm posterior to the globe,and the area of the subarachnoid space of the optic nerve from 3 mm to 5 mm posterior to the globe,all decreased significantly after performing eye movement exercises for 10 minutes and 30 minutes.These measures returned to baseline levels after three days of eye movement exercises,with significant differences observed across time points(P<0.05).Specifically,compared to baseline values,the diameter of the optic nerve sheath at 5 mm posterior to the globe decreased by 0.33 mm(95%CI:0.034-0.624,P=0.02)after performing 30 minutes of eye movement exercises.Additionally,the width of the subarachnoid space of the optic nerve at 3 mm and 5 mm posterior to the globe decreased by 0.2 mm(95%CI:?0.037-0.452,P=0.034)and 0.29 mm(95%CI:?0.265-0.344,P=0.01),respectively.Finally,the area of the subarachnoid space of the optic nerve from 3 mm to 5 mm posterior to the globe decreased by 0.21 mm2(95%CI:0.155-0.762,P=0.02).Conclusion This study initially proposes an eye movement manipulation method(eye movement exercise)that can reduce the subarachnoid space gap of the optic nerve posterior to the globe,including the direction,duration,rhythm,and frequency of eye movements.It was found that regular eye movements for a certain period of time can deform the optic nerve sheath,compress the subarachnoid space of the optic nerve posterior to the globe,and narrow its gap.As the duration and frequency of eye movement exercises increase,the width or area of the subarachnoid space of the optic nerve decreases more significantly.However,eye movement exercises cannot maintain the deformation of the optic nerve sheath for a long time,and after a certain period of time,the gap of the optic nerve sheath returns to baseline levels.

Objective:To evaluate the efficacy of peritoneal dialysis (PD) in the treatment of acute kidney injury (AKI) in critically ill neonates.Methods:It was a retrospective study. The baseline characteristic data, PD protocols, PD catheter placement methods and clinical outcomes of AKI neonates who underwent PD in the General Hospital of Ningxia Medical University between July 2015 and December 2024 were collected and analyzed.Results:(1) Among the 8 neonates with AKI, gestational age was (30.38±6.02) weeks, and birth weight was 1 397.5 (839.0, 2 312.5) g, with 6 premature infants. The time from birth to AKI onset was 144 (48, 294) hours. The leading cause of AKI was sepsis (6/8). The treatment time of PD was (93.12±37.20) hours. (2) Renal function recovery: After PD treatment, urine output was significantly increased ( Z=-3.29, P<0.001), and serum creatinine was significantly decreased ( t=2.66, P=0.032). (3) Hyperkalemia: Six out of 8 patients presented with hyperkalemia, which significantly decreased after PD treatment ( t=3.37, P=0.008). (4) Acid-base balance:Five out of 8 neonates had metabolic acidosis, and 3 of 5 neonates achieved basically complete correction (including lactic acidosis). There was no statistically significant difference in acid-base balance indicators before and after PD treatment (all P>0.05). (5) PD-related complications: Two out of 8 patients experienced peritoneal dialysate leakage, and no other PD-related complications occurred. (6) Outcomes: The hospital stay was 27.0 (8.0, 57.5) days. Four out of 8 neonates survived, while the other 4 neonates died after withdrawal of treatment. The primary cause was multiple organ failure. Conclusions:PD is a safe and effective treatment for neonatal AKI, facilitating early renal recovery and correction of electrolyte and acid-base imbalances.

The study aimed to investigate the expression of ITGB1 in gastric cancer tissues and its impact on the efficacy of immunotherapy,and to find a new biomarker for prognosis assessment and prediction of immunotherapy response in gastric cancer.By utilizing bioinformatics methods to analyze the transcriptomic data,clinical pathological characteristics,and survival information of gastric cancer patients in the Cancer Genome Atlas(TCGA)database,this study evaluates the expression of ITGB1 in gastric cancer and its correlation with clinical features.Furthermore,an in-depth analysis was conducted for evaluating the relationship of ITGB1 expression with immune infiltration,immune checkpoint-related genes,immune subtypes and immunotherapy response.Data showed that high ITGB1 expression in gastric cancer tissues is associated with later T stage,lower survival rates,and lower overall survival.Analysis of immune infiltration scores showed the score for CD4+T cells,CD8+T cells,neutrophils,macrophages and dendritic cells were higher in the high ITGB1 expression group.Additionally,the levels of immune checkpoint-related genes such as SIGLEC15,TIGIT,CD274,HAVCR2,CTLA4 and PDCD1LG2 were elevated in the high ITGB1 expression group,and the expression of ITGB1 was positively correlated with the expression of immune checkpoint-related genes including SIGLEC15,TIGIT,CD274,HAVCR2,CTLA4,LAG3 and PDCD1LG2.Analysis based on the data from the TISIDB database revealed differential expression of ITGB1 in various immune subtypes of gastric cancer,with significantly higher expression levels in the C6 subtype(TGF-β dominant type).The TIDE algorithm indicated a high score for the group with high ITGB1 expression,suggesting poor efficacy of immune checkpoint blockade therapy.To sum up,we find that high expression of ITGB1 in gastric cancer tissues is a poor prognostic indicator for gastric cancer patients,thus ITGB1 may serve as a potential biomarker for assessing prognosis and predicting the efficacy of immunotherapy in gastric cancer.

Objective:To investigate the effects of customized dental-bone supported osteotomy guide plate in bilateral sagittal split osteotomy.Methods:24 patients(48 sides)with maxillofacial deformity underwent BSSO were included.The maxillofacial region of all patients was scanned by CT,the plaster dental models were scanned using laser surface scanner,and the 3D models were established.The osteotomy guide plates of the inner horizontal and anterior sagittal bone incision of mandible ramus were manufactured by digital technology.All splits underwent operation with(27 side)and without(21 sides)the osteotomy guide plate respectively by the same doc-tor,and the time for the inner horizontal and anterior sagittal bone incision of mandible ramus was recorded.Postoperative CT scan was performed to evaluate the surgical effects according to the lingual split scale(LSS)classification.Results:The wound in all patients healed well and no serious complication was observed.The time for the inner horizontal and anterior sagittal bone incision of mandible ramus in plate group and no plate group was(125.67±2.23)s and(141.15±3.69)s respectively(P＜0.05).The probability of mandi-ble splitting according to Hunsuck standard osteotomy line increased from 42.86％to 66.67％,and the probability of osteotomy line passing through mandibular nerve canal decreased from 33.33％to 7.41％,by using osteotomy guide plate.In addition,LSS4 type of osteotomy line was avoided by using osteotomy guide plates.Data analysis showed that the split pattern of sagittal split osteotomy of the mandibular ramus was influenced by the application of osteotomy guide plates(P＜0.05).Conclusion:The customized dental-bone supported osteotomy guide plate is effective in the completion of the operation and reducing time consuming and surgical complication in BSSO.

Objective This study aims to investigate the role of gap junction mediated by connexin 43(Cx43)in renal injury induced by periodontitis in rats.Methods Twelve SPF-grade Wistar male rats were divided into a control group and a periodontitis group by using a completely random number table method,with six rats in each group.The control group rats were not treated,while the periodontitis group rats were subjected to wire ligation of the neck of their bilateral maxillary first molars to construct a periodontitis model.After 8 weeks of modeling,the rats were examined for clinical indicators of the periodontium.micro-CT scanning of the maxilla reconstructed its 3D structure and analyzed the absorption of alveolar bone.Histopathological changes in periodontal and renal tissues were detected.MitoSOX red reagent was used to determine reactive oxygen species(ROS)content in renal tissues.A biochemical reagent kit was used to detect serum oxidative stress biomarkers.Real-time fluo-rescent quantitative-polymerase chain reaction(qRT-PCR)was employed to determine Cx43,nuclear factor kappa-B(NF-κB),interleukin(IL)-1β,IL-6,BCL2-Associated X(Bax),B-lymphomatoma-2 gene(Bcl-2),and Caspase-3 mRNA were determined.Western blot analysis was used to detect Cx43,NF-κB,IL-1β,Bax,Bcl-2 and Caspase-3 protein.Re-sults micro-CT 3D reconstruction showed significant bone resorption of the first molar alveolar bone in the periodonti-tis group rats and decreased height of the alveolar ridge.The distance from the enamel cementum boundary to the top of the alveolar ridge in the periodontitis group was significantly higher than that inthe control group.The histopathological results showed a large number of inflammatory cells that infiltrated the periodontal tissue of the periodontitis group,and the alveolar bone was significantly absorbed.Rats in the periodontitis group also exhibited mild thickening of the glomer-ular basement membrane,dilation of the Bowman's capsule,and destruction of the brush-like edge of the renal tubules in the renal tissue.The MitoSOX red staining results showed a significant increase in ROS content in the renal tissue of the periodontitis group.The biochemical test results showed that the levels of superoxide dismutase and glutathione in the serum of rats with periodontitis decreased,while that of malondialdehyde increased.The results of qRT-PCR and Western blot showed that the expression levels of Cx43,IL-1β,IL-6,Bax,Caspase-3 mRNA and Cx43,IL-1β,NF-κB,Bax,Caspase-3 proteins in the periodontitis group significantly increased compared with those in the control group,while the expression levels of Bcl-2 mRNA and protein decreased.Conclusion Periodontitis may activate NF-κB sig-naling molecules by upregulating the expression of Cx43 in rat kidney tissues,leading to increased levels of inflamma-tion and apoptosis and ultimately inducing kidney injury.

Detailed knowledge on tissue-specific metabolic reprogramming in diabetic nephropathy (DN) is vital for more accurate understanding the molecular pathological signature and developing novel therapeutic strategies. In the present study, a spatial-resolved metabolomics approach based on air flow-assisted desorption electrospray ionization (AFADESI) and matrix-assisted laser desorption ionization (MALDI) integrated mass spectrometry imaging (MSI) was proposed to investigate tissue-specific metabolic alterations in the kidneys of high-fat diet-fed and streptozotocin (STZ)-treated DN rats and the therapeutic effect of astragaloside IV, a potential anti-diabetic drug, against DN. As a result, a wide range of functional metabolites including sugars, amino acids, nucleotides and their derivatives, fatty acids, phospholipids, sphingolipids, glycerides, carnitine and its derivatives, vitamins, peptides, and metal ions associated with DN were identified and their unique distribution patterns in the rat kidney were visualized with high chemical specificity and high spatial resolution. These region-specific metabolic disturbances were ameliorated by repeated oral administration of astragaloside IV (100 mg/kg) for 12 weeks. This study provided more comprehensive and detailed information about the tissue-specific metabolic reprogramming and molecular pathological signature in the kidney of diabetic rats. These findings highlighted the promising potential of AFADESI and MALDI integrated MSI based metabolomics approach for application in metabolic kidney diseases.

Understanding of the nephrotoxicity induced by drug candidates is vital to drug discovery and development. Herein, an metabolomics method based on air flow-assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI) was established for direct analysis of metabolites in renal tissue sections. This method was subsequently applied to investigate spatially resolved metabolic profile changes in rat kidney after the administration of aristolochic acid I, a known nephrotoxic drug, aimed to discover metabolites associated with nephrotoxicity. As a result, 38 metabolites related to the arginine-creatinine metabolic pathway, the urea cycle, the serine synthesis pathway, metabolism of lipids, choline, histamine, lysine, and adenosine triphosphate were significantly changed in the group treated with aristolochic acid I. These metabolites exhibited a unique distribution in rat kidney and a good spatial match with histopathological renal lesions. This study provides new insights into the mechanisms underlying aristolochic acids nephrotoxicity and demonstrates that AFADESI-MSI-based metabolomics is a promising technique for investigation of the molecular mechanism of drug toxicity.

Objective:To investigate the effects of metformin on the survival of patients with advanced non-small cell lung cancer (NSCLC).Methods:PubMed, EMbase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang and other databases were searched from the beginning of database construction to February 2020, relevant literatures were screened and included, and the characteristics of the literatures were extracted. RevMan 5.3 software was used to analyze progression-free survival (PFS), overall survival (OS), hazard ratio(HR) and 95% CI; the heterogeneity and publication bias were also evaluated. Results:A total of 11 studies were enrolled, and metformin did not improve PFS in patients with advanced NSCLC ( HR = 0.80, 95% CI 0.58-1.09, P = 0.15). The subgroup analysis results of different treatment strategies showed that metformin combined with tyrosine kinase inhibitor (TKI) ( HR = 0.71, 95% CI 0.32-1.57, P = 0.39), chemoradiotherapy ( HR = 0.97, 95% CI 0.59-1.61, P = 0.92), and immune checkpoint inhibitor (ICI) ( HR = 0.64, 95% CI 0.35-1.16, P = 0.14) did not improve the PFS. Metformin improved OS in patients with advanced NSCLC ( HR = 0.84, 95% CI 0.75-0.93, P = 0.001). Metformin combined with TKI ( HR = 0.68, 95% CI 0.38- 1.22, P = 0.19) and ICI ( HR =0.80, 95% CI 0.39-1.63, P = 0.54) did not improve OS of patients, while metformin combined with chemoradiotherapy could improve OS ( HR = 0.85, 95% CI 0.78-0.93, P < 0.01). No evidence of publication bias was shown in the funnel plot analysis. Conclusions:Metformin can prolong OS time in patients with advanced NSCLC, especially in patients undergoing metformin combined with radiotherapy and chemotherapy, or concurrent chemoradiotherapy.

OBJECTIVE: To explore the mediating role of psychological capital in the sense of occupational mission and work engagement in preschool teachers.METHODS: A method of stratified cluster sampling was used to select 464 preschool teachers from 16 kindergartens in a city of Hubei Province. Occupational Mission Scale, Psychological Capital Questionnaire and Job Involvement Questionnaire were used to investigate their sense of occupational mission, psychological capital and job engagement. RESULTS: The total score of occupational mission was(48.6±6.9); the total score of psychological capital was(87.1±11.8); and the total score of work engagement was(79.8±11.4). Occupational mission was positively correlated with job engagement [correlation coefficient(r) was 0.607, P<0.01].The self-efficacy, hope, tenacity and optimism were positively correlated with job engagement(r were 0.526, 0.544, 0.573, 0.415, respectively, P<0.01). The mediating effect of psychological capital on occupational mission and work engagement was 0.15, accounting for 26.8% of the total effect. CONCLUSION: The sense of occupational mission can directly or indirectly promote job engagement. The psychological capital plays a mediating role between occupational mission and job engagement.
