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.

BACKGROUND:Studies have shown that vision recovery with thinner grafts is faster and the risk of rejection is lower.In China,there is a lack of clinical efficacy analysis of different graftthicknesses after endothelial transplantation.Therefore,determining the optimal graftthickness is crucial for improving surgical efficacy. OBJECTIVE:To evaluate the effects of different graftthickness on vision recovery and other prognostic indexes after simple Descemet's stripping endothelial keratoplasty. METHODS:A total of 72 patients(72 eyes)with corneal endothelial decompensation who received simple Descemet's stripping endothelial keratoplasty at the General Hospital of Northern Theater Command from January 2013 to February 2023 were selected.There were 32 cases(32 eyes)in the thin graftgroup(＜100 μm)and 40 cases(40 eyes)in the thick graftgroup(≥100 μm).The best corrected visual acuity,corneal endothelial cell count,corneal graft transparency,postoperative complications and graftsurvival were observed in both groups before and 1,3,6,and 12 months after surgery. RESULTS AND CONCLUSION:The visual acuity after surgery was significantly improved in both groups,and the best corrected visual acuity 3 months after surgery in the thin graftgroup was better than that in the thick graftgroup(P＜0.05).There was no significant difference in the number of corneal endothelial cells and grafttransparency between the two groups 1 year after surgery(P＞0.05).There was no significant difference in the incidence of postoperative complications such as secondary glaucoma,graftimmune rejection and graftdisplacement between the two groups(P＞0.05).There was no significant difference in the 1-year survival rate of grafts between the two groups(93.8%vs.92.3%,P＞0.05).To conclude,simple Descemet's stripping endothelial keratoplasty is a safe and effective surgical method for corneal endothelial transplantation,and its postoperative efficacy is similar to that of traditional Descemet's stripping endothelial keratoplasty,and the graftimplantation method is simpler.Thinner grafts can provide optimal corrected vision earlier and complete corneal remodeling sooner.Therefore,in the treatment of corneal endothelial decompensation,thinner grafts are preferred to improve recovery time.

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.

Resistance to poly adenosine diphosphate(ADP)-ribose polymerase inhibitor(PARPi)presents a considerable obstacle in the treatment of ovarian cancer.F-box and tryptophan-aspartic(WD)repeat domain containing 11(FBXW11)modulates the ubiquitination of growth-and invasion-related factors in lung cancer,colorectal cancer,and osteosarcoma.The function of FBXW11 in PARPi therapy is still ambiguous.In this study,RNA sequencing(RNA-seq)showed that FBXW11 expression was raised in ovarian cancer cells that had been treated with PARPi.FBXW11 was abnormally expressed at low levels in high-grade serous ovarian cancer(HGSOC)tissues,and low levels of FBXW11 were associated with shorter overall survival(OS)and progression-free survival(PFS)in HGSOC patients.Overexpressing FBXW11 made ovarian cancer more sensitive to PARPi,while knocking down FBXW11 made it less sensitive.The four-dimensional(4D)label-free quantitative proteomic analysis revealed that FBXW11 targeted S100 calcium binding protein A11(S100A11)and promoted its degradation through ubiquiti-nation.The increased degradation of S100A11 led to less efficient DNA damage repair,which in turn contributed to increased PARPi-induced DNA damage.The role of FBXW11 in promoting PARPi sensitivity was also confirmed in xenograft mouse models.In summary,our study confirms that FBXW11 promotes the susceptibility of ovarian cancer cells to PARPi via affecting S10OA11-mediated DNA damage repair.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a child with Osteopathia striata with cranial sclerosis (OSCS) due to variant of AMER1 gene. METHODS: A child presented at the Affiliated Children's Hospital of Zhengzhou University in July 2024 due to growth and development retardation was selected as the study subject. A retrospective study was conducted to collect the child's clinical data. Peripheral blood samples (2 mL each) were collected from the child and her parents, and genomic DNA was extracted for whole exome sequencing (WES). Sanger sequencing was used for the verification of candidate variants. The pathogenicity of variant was rated according to the guidelines from American College of Medical Genetics and Genomics (ACMG). The study has been approved by the Medical Ethics Committee of the Children's Hospital Affiliated to Zhengzhou University (Ethics No.: 2024-108-001). RESULTS: The patient, a 4-year-and-10-month-old girl, presented with global developmental delay, short stature, cleft palate, distinct facial features, and hearing impairment. WES revealed that she has harbored a heterozygous c.790_794dup (p.Cys265Trpfs*19) variant of the AMER1 gene, which was not detected in either parent. Based on the guidelines from ACMG, the gene variant was classified as pathogenic (PVS1 + PS2 + PM2_supporting). As the result of a non-triplet base insertion in the coding region of the AMER1 gene, it has converted a codon originally encoding an amino acid into a stop codon, and led to a truncated protein, causing severe alteration and dysfunction of the protein. CONCLUSION The child was diagnosed with OSCS for clinical features such as global developmental delay, short stature, cleft palate, distinctive facial features, and hearing impairment, for which the de novo heterozygous frameshift variant AMER1: c.790_794dup (p.Cys265Trpfs*19) may be accountable. Above finding has expanded the mutational spectrum of OSCS and provided a basis for genetic counseling and prenatal diagnosis for the family.

Objective To evaluate the safety of two-port laparoscopic myomectomy through transumbilical laparoendoscopic single site surgery(TU-LESS)plus one auxiliary port in obese patients.Methods Clinical data of 139 cases who underwent two-port laparoscopic myomectomy from July 2020 to July 2023 were analyzed retrospectively,including 24 cases with body mass index(BMI)≥28 and 115 cases with BMI＜28.The patients underwent surgery through a transumbilical single-site port along with an additional left lower abdominal port equipped with a 5 mm trocar,utilizing the conventional multiport laparoscope and surgical instruments.The perioperative indexes were observed and compared between the two groups.Results A second auxiliary port was added due to operational challenge encountered in 1 case(BMI=31.6),and the other 138 procedures were successfully completed without conversion to other surgery.No severe intraoperative or postoperative complications occurred.There were no significant differences between the two groups in the perioperative indexes including operation time,intraoperative blood loss,hemoglobin difference before and after surgery,time to first postoperative exhaust,Visual Analogue Scale(VAS)of pain at 24 h after surgery,postoperative fever,postoperative hospital stay,and hospitalization costs(P＞0.05).Conclusion Two-port laparoscopic myomectomy through TU-LESS plus one auxiliary port for obese patients is safe and feasible.

Objective:To observe the longitudinal changes of symptoms in the irradiation area of patients with postoperative radiotherapy for breast cancer,and investigate the correlative symptom indexes for predicting acute radiation dermatitis during radiotherapy.Methods:This study was designed as a prospective longitudinal study.A total of 103 patients with breast cancer who received three-dimensional con-formal radiotherapy in The Fourth Hospital of Hebei Medical University from May 2022 to December 2022 were enrolled using convenience and purposive sampling methods.The patients received a total of 50 Gy/25 radiotherapy sessions.We conducted weekly observations of five symptoms-itching,pain,swelling,burning,and tightness-in the irradiated area,for a total of six weeks.The incidence of symptoms associ-ated with radiation dermatitis across different severity levels was compared.We calculated the optimal number of symptoms for the occur-rence of grade 2 or higher radiation dermatitis,evaluated the predictive effect using the subject's work characteristic curve(ROC),and com-pared the risk of radiation dermatitis with the number of symptoms by applying a binary Logistic regression.Results:A total of 103 patients were included in the study.The total severity scores of symptoms were 0(0,0),0(0,0),0(0,1),1(0,2),2(1,3),3(2,4),respectively,show-ing a gradually increasing trend.From the 20 Gy/10-fraction radiotherapy point onward to the completion of radiotherapy,symptom scores exhibited statistically significant deviations from baseline values(P<0.001).From the beginning of 30 Gy/15 sessions to the end of radiother-apy,symptom scores were higher in patients with grade 2 and above dermatitis compared to those with dermatitis of less than grade 2(Z=2.12,2.81,4.08,P=0.034,0.005,0.001);at the end of 50Gy/25 sessions,the incidence rates of pruritus,pain,swelling,tightness,and burning were 68.9%(71 cases),68.9%(71 cases),46.6%(48 cases),36.9%(38 cases),and 15.5%(16 cases),respectively.At the 30 Gy/15 and 40 Gy/20 radiotherapy sessions,the optimal number of predicted symptoms were two and three,respectively.The corresponding areas under the ROC curve were 0.632 and 0.666.Sensitivity values were 48.6%and 43.2%,while specificity values reached 77.3%and 81.8%,re-spectively(95%CI:0.517-0.746,0.558-0.775,P=0.027,0.005).The subjects were assigned into low-risk and high-risk groups using the op-timal cut-off values,and binary Logistic regression showed that the risks of grade 2 and higher radiation dermatitis in the high-risk group were 3.39 and 3.58 times higher than that in the low-risk group(OR=3.388,95%CI:1.400-8.197,P=0.007;OR=3.584,95%CI:1.430-8.985,P=0.006).Conclusions:The symptoms of radiation dermatitis have appeared early and worsened with the severity of dermatitis.We should closely observe these symptoms throughout treatment.The risk of grade 2 and above radiation dermatitis increased when the number of symptoms was≥2 at 30 Gy/15 times and≥3 at 40 Gy/20 times.
