Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

AIM:To clarify the expression characteristics and regulatory role of the long non-coding RNA(lncRNA)metastasis-associated lung adenocarcinoma transcript 1(MALAT1)in oxidative stress and apoptosis of H2O2-induced human lens epithelial cell line HLE-B3.METHODS: HLE-B3 cells were divided into Control group and H2O2 group(cultured with 200 μmol/L H2O2 for 24 h). Levels of reactive oxygen species(ROS)and cell apoptosis rates were detected by flow cytometry. Activities of superoxide dismutase(SOD)and catalase(CAT)were measured using kits, MALAT1 expression was quantified by real-time quantitative PCR, and its cellular localization was determined by fluorescence in situ hybridization. After selecting the Si-MALAT1 sequence with the highest silencing efficiency, the groups were established as Control, H2O2, H2O2+Si-NC, and H2O2+Si-MALAT1. Immunofluorescence staining was employed to detect the apoptosis marker TUNEL and Nrf2 nuclear translocation. RESULTS:Compared with the Control group, the H2O2group exhibited significantly elevated ROS levels, markedly decreased SOD and CAT activities(both P<0.001), and a significantly increased apoptosis rate(P<0.01). MALAT1 expression was upregulated(P<0.01)and localized in the nucleus. After silencing MALAT1, H2O2-induced cell apoptosis was significantly inhibited(P<0.01).CONCLUSION: H2O2-induced oxidative stress can increase the expression of MALAT1, and silencing MALAT1 reduces oxidative stress damage and apoptosis, providing a potential target for preventing and treating cataracts.

Objective: To investigate the relationship between night-time noise exposure and depressive symptoms among junior and senior high school students, so as to provide evidence to support strategies for promoting their physical and mental health. Methods: From September 2024 to December 2025, 2 900 junior and senior high school students were selected using stratified cluster random sampling in the three cities of Nanning, Lhasa, and Yanji. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess depressive symptoms in junior and senior high school students, and a noise exposure survey was conducted. Chi-square test was used to compare the prevalence of depressive symptoms among junior and senior high school students with different types of night-time noise exposure, and Logistic regression models were employed to examine the association between night-time noise exposure and depressive symptoms among junior and senior high school students. Results: The prevalence of depressive symptoms among junior and senior high school students without night-time noise exposure was 33.0%, while that among junior and senior high school students with night-time noise exposure was 49.0%; the difference was statistically significant ( χ 2= 45.85 , P <0.01) . After adjusting for gender, age and region, Logistic regression analysis showed that exposure to night-time traffic noise, neighborhood noise, air conditioner noise, and other types of noise showed increased risk of detecting depressive symptoms in junior and senior high school students ( OR =2.22, 1.84, 2.41, 2.17, all P <0.05). Conclusion Night-time noise exposure is associated with an increased risk of depressive symptoms among junior and senior high school students.

AIM: To compare the postoperative clinical outcomes of two diffractive extended depth-of-focus intraocular lenses(IOLs), the AMEUH and the Tecnis Symfony IOL.

METHODS:This prospective cohort, multicenter study enrolled patients with cataract who underwent cataract phacoemulsification with IOL implantation at three hospitals between October 2024 and June 2025. Patients were divided into the AMEUH group and the ZXR00 group according to the implanted IOL. The AMEUH group included patients implanted with diffractive extended depth-of-focus IOL, and the ZXR00 group included patients implanted with the Tecnis Symfony IOL. At 6 mo postoperatively, ocular biometric parameters, photopic uncorrected distance visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA), uncorrected near visual acuity(UNVA), corrected distance visual acuity(CDVA), distance-corrected intermediate visual acuity(DCIVA), and distance-corrected near visual acuity(DCNVA); mesopic CDVA, DCIVA, and DCNVA, defocus curves, manifest refraction, contrast sensitivity, adverse visual symptoms, spectacle independence, patient satisfaction, and intraocular pressure were compared between the two groups.

RESULTS:A total of 83 patients(83 eyes)were included in this study, including 31 males(31 eyes)and 52 females(52 eyes), with a mean age of 63.18±10.30 y. The AMEUH group included 41 patients(41 eyes), aged 67.00(60.00, 72.00)y, including 13 males and 28 females. The ZXR00 group included 42 patients(42 eyes), aged 62.00(57.50, 69.00)y, including 18 males and 24 females. The 77 patients completed 6 mo postoperative follow up, with 6 patients lost to follow up(3 from the AMEUH group and 3 from the ZXR00 group). There were no significant differences in ocular biometric parameters between the two groups postoperative 6 mo(all P>0.05). No significant differences were observed in photopic UDVA, UIVA, UNVA, CDVA, and DCIVA, or in mesopic CDVA and DCIVA between the two groups(all P>0.05). However,photopic and mesopic DCNVA in the AMEUH group were significantly better than in the ZXR00 group(both P<0.05). The effective depth-of-focus in the AMEUH group was increased by 0.5 D compared with the ZXR00 group. Significant differences were observed in manifest refraction between the two groups(P<0.05). Under specific lighting conditions and spatial frequencies, contrast sensitivity in the AMEUH group was significantly better than in the ZXR00 group(all P<0.05). The incidences of glare, halos, and blurred vision in the AMEUH group were all significantly lower than in the ZXR00 group(all P<0.05). There were no significant differences in spectacle independence for distance, intermediate, and near vision, or in patient satisfaction for distance and intermediate vision between the two groups(all P>0.05). However, patient satisfaction for near vision in the AMEUH group was significantly higher than in the ZXR00 group(P<0.05).

CONCLUSION:The diffractive extended depth-of-focus IOL AMEUH further extends the depth-of-focus through a higher-order aspheric optical design based on a diffractive design, providing comparable efficacy to the Symfony IOL in improving distance and intermediate vision. Meanwhile, benefiting from its higher add power, it provides superior near visual performance, and reduces spectacle dependence. The AMEUH IOL is associated with a lower incidence of postoperative adverse visual symptoms, as well as favorable safety, and high patient satisfaction.

Phacoemulsification represents the mainstream, efficient, and safe surgical modality for cataract treatment, and continuous technological advances have further improved the safety profile of this procedure in ordinary patients. However, patients with high myopia feature inherent anatomical abnormalities of the eyeball, leading to a fundamental incompatibility with conventional phacoemulsification protocols. Such patients face a markedly elevated risk of both anterior and posterior segment perioperative complications, posing a persistent clinical challenge in cataract surgery. Focusing on the unique ocular anatomical characteristics associated with high myopia, this review systematically summarizes the distinct traumatic effects and pathological impacts of phacoemulsification on the anterior and posterior ocular segments of affected patients. Moving beyond generalized discussions of routine cataract management, it consolidates clinical evidence specific to this special-population patients, aiming to provide refined references for perioperative risk prevention and control in cataract patients complicated with high myopia.

Objective To explore the application effect of prone position ventilation combined with veno-venous extracorporeal membrane oxygenation (VV-ECMO) in the treatment of severe primary graft dysfunction (PGD) after lung transplantation. Methods The clinical data of 75 lung transplant recipients who developed severe PGD after lung transplantation and were treated with VV-ECMO from January 2021 to June 2024 at Wuxi People's Hospital Affiliated to Nanjing Medical University were collected. The patients with severe graft dysfunction after lung transplantation were divided into VV-ECMO group (control group, 45 cases) and prone position ventilation combined with VV-ECMO group (treatment group, 30 cases). The general data of the two groups of patients were compared, including the donors' clinical data (age, gender and oxygenation index, etc) and the recipients' clinical data [gender, age and body mass index (BMI), etc]. Cox regression analysis was used to analyze the influencing factors of the recipients' 30-day, 90-day and 180-day survival after surgery. The survival curves of the two groups of recipients were drawn using Kaplan-Meier method and compared using the log-rank test. Results The intensive care unit (ICU) stay time, ECMO application time and ventilator use time of control group were longer than those of treatment group. The proportion of male recipients and the BMI of control group were lower than those of treatment group. The 30-day, 90-day and 180-day survival of control group was worse than that of treatment group, and the differences were statistically significant (all P<0.05). The univariate Cox regression analysis of the recipients' 30-day survival after surgery showed that the recipients' BMI, history of diabetes, enlargement of the right atrium and right ventricle, intraoperative blood transfusion volume and intraoperative red blood cell transfusion volume were statistically significant (all P<0.05). The multivariate Cox regression analysis showed that the history of diabetes and enlargement of the right atrium and right ventricle were risk factors affecting the 30-day survival of lung transplant recipients (all P<0.05). The univariate Cox regression analysis of the recipients' 90-day survival after surgery showed that the recipients' BMI, history of diabetes, enlargement of the right atrium and right ventricle, intraoperative blood transfusion volume, intraoperative red blood cell transfusion volume and group variable were statistically significant (all P<0.05). The multivariate Cox regression analysis showed that the history of diabetes, enlargement of the right atrium and right ventricle and group variable were risk factors affecting the 90-day survival of lung transplant recipients (all P<0.05). The univariate Cox regression analysis of the recipients' 180-day survival after surgery showed that the recipients' BMI, history of diabetes, right atrium and right ventricle enlargement, intraoperative blood transfusion volume, intraoperative red blood cell transfusion volume and group variable were statistically significant (all P<0.05). The multivariate Cox regression analysis showed that the history of diabetes, enlargement of the right atrium and right ventricle and group variable were risk factors affecting the 180-day survival of lung transplant recipients (all P<0.05). The 30-day, 90-day and 180-day survival rates of control group were lower, and the differences between the two groups were statistically significant (all P<0.05), with a median survival time of 100 days in control group. Conclusions In the clinical treatment of severe PGD after lung transplantation, prone position ventilation combined with VV-ECMO may shorten ECMO application time, invasive ventilation time and ICU stay time, and improve the short-term prognosis of lung transplantation.

The regulatory processes in developmental biology research are significantly influenced by long non-coding RNAs (lncRNAs). However, the dynamics of lncRNA expression during human tooth development remain poorly understood. In this research, we examined the lncRNAs present in the dental epithelium (DE) and dental mesenchyme (DM) at the late bud, cap, and early bell stages of human fetal tooth development through bulk RNA sequencing. Developmental regulators co-expressed with neighboring lncRNAs were significantly enriched in odontogenesis. Specific lncRNAs expressed in the DE and DM, such as PANCR, MIR205HG, DLX6-AS1, and DNM3OS, were identified through a combination of bulk RNA sequencing and single-cell analysis. Further subcluster analysis revealed lncRNAs specifically expressed in important regions of the tooth germ, such as the inner enamel epithelium and coronal dental papilla (CDP). Functionally, we demonstrated that CDP-specific DLX6-AS1 enhanced odontoblastic differentiation in human tooth germ mesenchymal cells and dental pulp stem cells. These findings suggest that lncRNAs could serve as valuable cell markers for tooth development and potential therapeutic targets for tooth regeneration.

Objective To compare the 12-month efficacy and safety of N-butyl cyanoacrylate (NBCA) versus radiofrequency ablation (RFA) in treating great saphenous vein (GSV) insufficiency. Methods A total of 155 patients with GSV insufficiency from five centers were randomly allocated to the NBCA group or RFA group. Postoperative efficacy and safety outcomes were evaluated. Results Immediate postoperative closure rates of the GSV trunk were 100% in both groups. The closure rates of NBCA and RFA group were 98.6% and 98.5% at 3 months, 97.1% and 98.5% at 6 months, 98.1% and 95.9% at 12 months, with no statistically significant differences (P>0.05). After treatment, CEAP classification improved significantly from baseline in both groups. In terms of safety, 1 case of phlebitis, 1 case of ablation-related thrombus extension (ARTE) and 2 cases of calf muscle venous thrombosis(CMVT) occurred in the NBCA group, while 2 cases of limb numbness, 1 case of persistent thigh pain and 2 cases of CMVT in the RFA group. All reported serious adverse events in both groups were assessed as unrelated to the medical device or the trial procedure. Conclusions NBCA demonstrates non-inferior efficacy and safety compared to RFA for treating GSV insufficiency over 12 months.

AIM: To design and construct recombinant epitope nucleotides vaccine of glycoprotein B(gB)and glycoprotein D(gD)of herpes simplex virus type 1(HSV-1), and to investigate its immunoprotective effects and tissue expression in animal models.METHODS: The HSV-1 gB and gD epitope genes were selected and tandem assembled to construct the recombinant protein-coding gene X, which was transducted into the prokaryotic expression vector pET28(a). The recombinant protein was synthesized and utilized to generate monoclonal antibodies, which were subsequently used to immunize New Zealand white rabbits. The immunogenicity of the purified protein and the presence of polyclonal antibodies in the serum were tested through separating serum from cardiac blood, and the serum antibody titers were determined. The pcDNA3.1-X was successfully constructed as a eukaryotic expression vector and immunized the female BALB/c mice aged 4 to 6 wk via intramuscular injection. Serum antibodies and immune-related cytokines were quantified using enzyme-linked immunosorbent assay(ELISA). The expression of the X protein in the ocular, trigeminal ganglion, and brain tissues of the mice was assessed.RESULTS: The target polyclonal antibody was identified with a serum antibody titer of 1:3200 in the rabbit serum after immunized by recombinant protein X. Upon immunizing mice with the eukaryotic recombinant plasmid pcDNA3.1-X, the concentration of HSV-1 serum IgM antibodies of the experimental group was 12.13±0.85 ng/L, which was significantly higher than that of the vector control group(0.49±0.44 ng/L; t=21.07, P<0.001). The concentrations of cytokines interleukin IL-2, IL-4, IL-10, and IFN-γ in the experimental group were 11.63±0.60, 22.65±1.47, 85.75±14.12, and 114.90±6.39 ng/L, respectively, all of which were significantly higher than those in the vector control group and the blank control group(all P<0.05). Immunohistochemical staining revealed the presence of target protein X in the eyeball, trigeminal ganglion, and brain tissue.CONCLUSION: The HSV-1 gB and gD tandem epitope nucleotides vaccine pcDNA3.1-X was successfully constructed, which activates a remarkable immune response and is stably expressed in the eyeball, trigeminal ganglion, and brain tissue. This study provides a foundation for further research of an HSV-1 recombinant antigen epitope tandem vaccine.

Cataract surgery is one of the most common ophthalmologic procedures. Advances in technology and medical policies have made it more precise. Residual refractive errors and deviation of target diopters are a main cause of dissatisfaction among patients. Refractive enhancement after cataract surgery can correct or eliminate these errors, improving patients' visual quality of life. There are multiple options for correcting residual refractive errors. The best approach depends on factors like the cause of the error, degrees of residual refractive errors, type of intraocular lens, ocular comorbidities, and patient preference. This paper summarizes the incidence and types of residual refractive errors, advancements in refractive enhancement surgeries, and provides practical solutions for clinical practice.
