AIM: To investigate the influence of pterygium thickness and area on corneal refractive status.METHODS: Prospective longitudinal study. A total of 60 cases(60 eyes)of pterygium patients admitted to our hospital from January 2024 to September 2024 were randomly selected. All patients underwent pterygium excision combined with pedicle conjunctival flap transplantation for treatment. Optical coherence tomography(OCT)was used to measure the preoperative thickness of patient's pterygium, and a digital slit lamp microscope was used to measure the area of pterygium. The corneal refractive status(degree of corneal astigmatism and average curvature)and changes in uncorrected visual acuity of patients before surgery, 1 d, 1, and 3 mo after surgery were compared. The relationship between preoperative thickness and area of pterygium in patients and corneal refractive status indicators at different postoperative time points were analyzed, and Logistic regression was used to analyze the impact of pterygium thickness and area on postoperative visual improvement in patients.RESULTS: All patients completed follow-up after surgery for 3 mo. At 3 mo after surgery, visual acuity improved in 21 eyes(35%). The results of bivariate Pearson correlation analysis showed that the thickness and area of pterygium positively correlated with the degree of corneal astigmatism and uncorrected visual acuity before surgery and 1 d, 1, and 3 mo after surgery(all P<0.05), and negatively correlated with the average corneal curvature before surgery and 1 d, 1, and 3 mo after surgery(all P<0.05). Logistic regression analysis showed that the thickness and area of pterygium before surgery, high degree of corneal astigmatism, and low uncorrected visual acuity(large LogMAR value)were all risk factors for poor postoperative visual improvement in patients(OR>1, P<0.05). The large average corneal curvature before surgery was a protective factor for poor postoperative visual improvement in patients(OR<1, P<0.05).CONCLUSION: The increase in thickness and area of pterygium can, to some extent, improve corneal astigmatism, reduce the average curvature of the cornea, and affect postoperative visual recovery.

Objective On the basis of the theory of the tumor metastatic state, this work aims to explore the metastasis trajectories and peripheral immune response patterns in patients with non-small cell lung cancer (NSCLC) receiving vital qi-strengthening and toxin-eliminating therapy (Fuzheng Juandu) and reveal the value of peripheral immunity in assessing vital qi deficiency during metastasis. Methods A retrospective study design was adopted. Patients with NSCLC admitted from January 1, 2018, to October 31, 2025 were enrolled. Data on metastasis status and peripheral immune indices were collected at the follow-up time points of one, two, three, and five years. Group-based trajectory modeling was used to fit metastasis trajectories, and the independent predictors of trajectory grouping were analyzed through multifactor and multiclassification logistic regression. Results A total of 184 patients with NSCLC were included, and three different groups of metastasis trajectories were identified, namely, the low-risk stable (46.74%, n=86), low-risk rising (13.59%, n=25), and high-risk stable (39.67%, n=73) groups. Univariate analysis revealed substantial differences in peripheral immune indices among the three trajectory groups. Multivariate analysis showed that TNM stage, absolute neutrophil count, lymphocyte count, absolute monocyte count, platelet volume, SAA:CRP ratio, and NLR were independent predictors of the low-risk rising group, whereas TNM stage, absolute monocyte count, basophil count, SII, and NLR were independent predictors of the high-risk stable group. Conclusion Under Fuzheng Juandu therapy, patients with NSCLC exhibit three distinct metastasis trajectories, each corresponding to a specific peripheral immune response pattern. Elucidating these peripheral immune response patterns may facilitate the objective quantification of the degree of vital qi deficiency, prediction of future metastasis risk, and providing an important reference for the individualized clinical implementation of Fuzheng Juandu therapy.

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

Objective To explore the value of magnetic resonance imaging(MRI)T2-weighted imaging(T2WI)and diffusion-weighted imaging(DWI)sequences in evaluating the therapeutic effect of neoadjuvant chemoradiotherapy(nCRT)for advanced rectal cancer.Methods A retrospective analysis was conducted on 124 patients with advanced rectal cancer who received nCRT from November 2020 to November 2023 in Dazhou Integrated TCM&Western Medicine Hospital.All patients underwent radical resection of rectal cancer at 6-8 weeks after the end of nCRT.MRI scans were performed before nCRT and at 6-8 weeks after the end of nCRT.The differences in tumor long and short diameters,signal intensity in tumor(SIT),apparent diffusion coefficient(ADC)and other parameters were measured,and the MRI tumor regression grade was analyzed.Surgery was performed at 3 days after the second examination.The patients were divided into grade 0-1 group and grade 2-3 group according to the postoperative pathological tumor regression grade.The differences of MRI parameters before and after treatment were compared between groups.The consistency of T2WI sequence and DWI sequence in the diagnosis of tumor regression grade after nCRT was analyzed.ROC curve was used to analyze the value of MRI parameters in evaluating the therapeutic effect of nCRT.Results The differences of tumor long diameter,short diameter,SIT and ADC measured by twice MRI examination in grade 0-1 group were increased as compared with grade 2-3 group(P<0.05).MRI detected MRI tumor regression grade 1 in 28 cases(22.58%),grade 2 in 30 cases(24.19%),grade 3 in 31 cases(25.00%),grade 4 in 25 cases(20.16%)and grade 5 in 10 cases(8.06%).Consistency analysis showed that MRI had a sensitivity,specificity,accuracy rate and Kappa value of 92.45%,87.32%,89.51%and 0.788 in evaluating postoperative tumor regression grade.ROC analysis revealed that the AUC of MRI parameters such as differences in tumor long diameter,short diameter,SIT and ADC measured by twice MRI examinations in evaluating the nCRT efficacy ranged from 0.827 to 0.921,and the AUC of combined evaluation was 0.928(P<0.05).Conclusion The combined evaluation of MRI T2WI and DWI sequences can be served as an effective tool for evaluating the therapeutic effect of nCRT for advanced rectal cancer.
