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 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.

Neoadjuvant therapy for locally advanced colorectal cancer has made great progress in the past 20 years, but there are still limitations such as side effects, organ dysfunction and unsatisfactory control of metastasis. In recent years, with the improvement of surgical techniques and further development of molecular research, how to further improve local control, reduce distant metastasis, and even avoid surgery according to clinical remission to achieve organ preservation, is the current demand and research goal. With the advancement of molecular research, colorectal cancer has different treatment strategies based on microsatellite status. For patients with microsatellite instability locally advanced colorectal cancer, immune checkpoint inhibitor therapy significantly increased the pathologic complete response rate, reduced the incidence of adverse events and improved organ function compared with conventional chemoradiotherapy. For patients with microsatellite stable locally advanced colon cancer, neoadjuvant therapy is still in the exploratory stage. The standard of care is surgery combined with perioperative chemotherapy. For microsatellite stable locally advanced rectal cancer, the complete response rate is improved by enhancing neoadjuvant therapy, which helps to preserve organs. On the other hand, selective radiotherapy preserves organ function and improves quality of life. This article reviews the neoadjuvant treatment strategies for locally advanced colorectal cancer based on organ-sparing strategies.
