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.

This paper systematically reviewed the concept of authentication studies on traditional Chinese medicine (TCM) classics and the research achievements of scholars across historical and contemporary periods. We categorized the authentication studies on TCM classics into four types, including work-oriented authentication research, metho-dological studies on authentication, extended authentication research, and single-book authentication. Multiple methods were applied comprehensively, including investigating bibliographic documents of successive dynasties, analyzing the academic contents of medical books, studying the textual characteristics of medical books, examining the cited references in medical books, verifying the biographies of authors, and analyzing the interpolations and accretions in medical books, to distinguish the authenticity of TCM classics. The academic value of authenticity identification of TCM classics is concluded in three aspects,i.e. it serves as an important means to distinguish authenticity from falsehood in TCM classics, an important guarantee for inheriting the essence of TCM literature, and a key to unlocking the academic treasure trove of TCM classics and achieving inheritance-based innovation, which will lay a solid documentary foundation for constructing identification methodologies and standardized systems.

Pyroptosis is a new type of programmed cell death that can efficiently enhance the immune response by inducing cell lysis and inflammation, thereby facilitating tumor immunotherapy. Recently, an increasing number of studies have revealed close relationships between pyroptosis and nanomedicine, which has been regarded as a new strategy for developing nanomedicine-based immunotherapy for highly effective therapy of various cancers. In this review, the development and associated signaling pathways for pyroptosis, including the correlation between pyroptosis and anti-tumor immunity, were first presented. Then, various nanomedicines that induce pyroptosis for tumor therapy, especially immunotherapy, were systematically discussed. Finally, the current challenges and constructive perspectives in this field were proposed.

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 ubiquitination. 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 S100A11-mediated DNA damage repair.

Non-small cell lung cancer (NSCLC), a leading cause of cancer-related deaths worldwide, remains a significant clinical challenge despite advances in immune checkpoint inhibitors therapy, with drug resistance persisting as a major obstacle. Palmitoylation, a critical post-translational modification (PTM) primarily catalyzed by palmitoyltransferases of the zinc finger DHHC-type (ZDHHC), has recently demonstrated important implications in NSCLC. This review aims to elucidate the mechanisms and clinical potential of ZDHHC-mediated protein palmitoylation in NSCLC progression and immune escape.

The bioactivity-guided isolation of potentially active natural products has been widely utilized in pharmaceutical discovery. In this study, by screening fungal extracts against coxsackievirus B3 (CVB3), three new aspochalasins, templichalasins A‒C (1‒3), along with six known aspochalasins (4‒9) were isolated from an active extract derived from the endophytic fungus Aspergillus templicola LHWf045. Compound 1 features a unique 5/6/5/7/5 pentacyclic ring system, while compounds 2 and 3 possess unusual 5/6/6/7 tetracyclic skeletons. Their structures were characterized through extensive spectroscopic analyses, electronic circular dichroism (ECD) calculations, and single-crystal X-ray diffraction analysis. Additionally, we demonstrated that compound 4 can be readily converted into compounds 1‒3 under mild acidic conditions and proposed a plausible mechanism for this conversion. Bioactivity evaluation of compounds 1‒9 against CVB3 revealed the inhibitory effects of all compounds against the virus. Notably, compound 9 exhibited superior antiviral activity, surpassing the commercial drug ribavirin in selectivity index (SI) value.

ObjectiveTo sum up the clinical features of 5α-reductase type 2 deficiency (5α-RD2) complicated by central precocious puberty (CPP), and provide experience for clinicians. MethodsA retrospective review was conducted of child patients with 5α-RD2 followed up to puberty at a single tertiary pediatric center, in whom 6 cases developed CRP. Clinical characteristics and treatment history of them were analyzed. A literature review was also performed to investigate possible mechanisms underlying the co-occurrence of 5α-RD2 and CPP. ResultsThe median age at initial presentation was 5.55 years (IQR 3.50-7.20). Common clinical features included micropenis and hypospadias. Median stretched penile length (SPL) was 2.25 cm (IQR 1.8-2.8), with an SPL-SDS of -4.5 (IQR -3.1 to -5.8). Median external masculinization score (EMS) and Prader scores were 8.5 (IQR 5.0-9.0) and 4.5 (IQR 3.0-5.0), respectively. Pubertal onset occurred at a median age of 8.70 years (IQR 7.80-9.00). Three patients were overweight or obese. Five had received 2.5% dihydrotestosterone (DHT) gel prior to pubertal onset, with a median cumulative dose of 205.5 mg/kg (IQR 72.0-660.3 mg/kg) with DHT gel therapy. Notably, one patient with normal body mass index (BMI) and no history of androgen or gonadotropin therapy also exhibited early pubertal onset at 8.4 years. ConclusionCPP in children with 5α-RD2 may be associated with prior dihydrotestosterone (DHT) gel therapy and elevated BMI; however, a potential intrinsic link to the underlying disorder cannot be excluded. Further studies are needed to elucidate the pathophysiological mechanisms.

Objective:
To explore the associations of moderate to vigorous intensity physical activity (MVPA) and sedentary behavior (SB) among primary and secondary school students and their parents, so as to provide a scientific basis for formulating targeted physical activity promotion strategies for children and adolescents.
Methods:
From 2021 to 2022, basic information and 24 h movement behaviors of 2 484 pairs of students and their parents were collected from five primary and secondary schools in Haizhu District, Guangzhou City, with a convenient sampling combining with cluster sampling method. Component regression models were constructed to analyze the relationship between parental MVPA, SB and primary and secondary school students MVPA and SB, and a component isochronous substitution model was used to explore the effects of mutual substitution between parental MVPA, residual components (time use components other than SB during the 24 h period), and SB on the behavioral activities of MVPA and SB in primary and secondary school students.
Results:
Parental MVPA and SB of students in grade 1 to 3 were positively correlated with both students MVPA and SB ( β=0.06, 0.12, P <0.01). The component isochronous substitution model showed that substituting 10 and 20 minutes of MVPA for SB by parents in grade 1 to 3 was associated with an increase in MVPA of students, and substituting 10 and 20 minutes of residual ingredients for SB was associated with a decrease in SB of students, with mean changes of 0.8 (95% CI =0.4-1.2) and 1.4 (95% CI =0.7-2.2) and -1.4 (95% CI =-1.7 to -1.1) and -2.9 (95% CI =-3.4 to -2.3)( P <0.05). No statistically significant associations were observed between parents of students in grades 4 to 6 and 7 to 9 and students physical activity and sedentary behaviour ( P >0.05).
Conclusions
Parents of students in grades 1 to 3 increases MVPA and decrease SB are beneficial to increase MVPA and decrease SB of students. Parents could promote physical activity among primary and secondary school students, and the intervention gateway should be advanced, with the low grades as the optimal intervention period.

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.
