OBJECTIVE: To investigate the effectiveness of digital three-dimensional (3D) assisted unilateral biportal endoscopy (UBE) in the treatment of highly isolated lumbar disc herniation (LDH) with translaminar approach. METHODS: The clinical data of 59 patients who met the selection criteria and underwent UBE treatment due to highly isolated LDH between January 2022 and December 2023 were retrospectively analyzed. Among them, 25 cases were treated with digital 3D assisted translaminar approach (observation group) and 34 cases were treated with interlaminar approach (control group). There was no significant difference in gender, age, disease duration, surgical segment, and preoperative visual analogue scale (VAS) score and Oswestry disability index (ODI) between the two groups ( P>0.05). The operation time, intraoperative blood loss, and lateral articular surface preservation rate were recorded and compared between the two groups. VAS score and ODI were used to evaluate the improvements of pain and function before operation and at 3 and 6 months after operation. The modified MacNab criteria was used to evaluate the effectiveness at last follow-up. RESULTS: One patient in the control group had dural tear, and the other patients had no nerve injury, infection, dural tear, or other related complications. There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). Patients in both groups were followed up 6-13 months, with an average of 8.3 months. The lateral articular surface preservation rate in the observation group was significantly higher than that in the control group ( P<0.05). Three patients in the observation group and 2 patients in the control group had calf muscle venous thrombosis, which was cured after anticoagulant treatment with rivaroxaban and delayed exercise time. There was no recurrence or second operation during the follow-up period. The VAS score and ODI of the two groups at 3 and 6 months after operation significantly improved when compared with those before operation ( P<0.05). There was no significant difference between the two groups at each time point after operation ( P>0.05). At last follow-up, the effectiveness was evaluated according to the modified MacNab criteria, and there was no significant difference in the evaluation grade and excellent and good rate between the two groups ( P>0.05). CONCLUTION UBE via translaminar approach is safe and effective for the treatment of highly isolated LDH, which is beneficial to protect the facet joint, maintain spinal stability, and reduce soft tissue injury. With the assistance of digital 3D technique, preoperative planning can be performed accurately.

Objective:To explore the predictive value of preoperative peripheral hematological parameters combined with clinicopathological features for cervical lymph node metastasis（CLNM） in patients with laryngeal squamous cell carcinoma（LSCC）, and to construct and validate a nomogram model for CLNM. Methods:A retrospective analysis was conducted on the clinical data of 264 LSCC patients who underwent surgical treatment and were pathologically confirmed, collected from the Second Affiliated Hospital of Shandong First Medical University and Taian 88 Hospital. Specifically, 161 patients from one hospital were allocated to the training cohort, while 103 patients from another hospital constituted the validation cohort. Based on postoperative pathological results, patients were categorized into CLNM-positive and CLNM-negative groups. The general clinical data, clinicopathological features, and hematological parameters of the two groups were analyzed and compared. A preoperative predictive model for CLNM was developed using logistic regression analysis, followed by validation and sensitivity analysis to evaluate the robustness of the model's predictive performance. Results:The results showed that there were significant differences in tumor location, tumor size, tumor differentiation, neutrophil percentage, lymphocyte count, lymphocyte percentage, c-reactive protein（CRP）, fibrinogen, neutrophil-to-lymphocyte ratio（NLR）, platelet-to-lymphocyte ratio（PLR）, systemic immune-inflammation index（SII）, systemic inflammation response index（SIRI）, and prognostic inflammatory index（PIV） between the CLNM-positive and CLNM-negative groups（P<0.05）. Lasso regression identified tumor location, clinical T stage, tumor size, tumor differentiation degree, red blood cell distribution width（RDW） -coefficient of variation（RDW-CV）, CRP, FIB, D-dimer, NLR, and lymphocyte-to-monocyte ratio（LMR） were the most predictive parameters. Multivariate logistic regression revealed that tumor location, tumor size, tumor differentiation degree, CRP, and NLR were independent risk factors for CLNM in LSCC patients（P<0.05）. A nomogram was constructed based on these five factors. The model demonstrated excellent discrimination, with a C-index of 0.837（95%CI 0.766-0.908） in the training cohort and 0.809（95%CI 0.698-0.920） in the validation cohort. Calibration curves and DCA curves in both cohorts confirmed the clinical utility of the model. Sensitivity analysis further supported the robustness of the results, showing good discrimination and calibration across different age and BMI subgroups. Conclusion:Tumor location, tumor size, tumor differentiation degree, CRP, and NLR were independent risk factors for CLNM in LSCC patients. The nomogram based on these variables exhibits strong discrimination, calibration, and clinical applicability, and may serve as a valuable tool for preoperative risk assessment and individualized treatment planning.

In modern society, sugary foods have become an integral part of many people′s lives. However, excessive sugar consumption has adverse effects on both overall health and oral health, serving as a contributing factor to the global increasing incidence in oral diseases, cardiovascular diseases, cancers, obesity, and diabetes. In response to the health risks related to high-sugar diets, the World Health Organization (WHO) and World Dental Federation (FDI) have proposed initiatives and recommendations, with various governments implementing different policies and strategies to reduce sugar intake. Chinese government has also taken proactive measures. The "Healthy China Action (2019-2030)" initiative introduced by the State Council in 2019 established a crucial benchmark in limiting the average daily intake of added sugar to 25 g per person forward to 2030. Experts from Chinese Center for Disease Control and Prevention and the field of oral health have meticulously examined the impacts of sugar reduction on oral health, as well as strategies, methods, and practical considerations related to reducing sugar intake through several meeting and wrote the "Expert consensus: reducing free-sugar for caries prevention", which was subsequently reviewed and revised based on the feedback from multiple stakeholders. They have conducted thorough analyses of global trends in sugar reduction and best practices to provide valuable insights to China for crafting effective policies and strategies on sugar reduction. This consensus mainly includes the classification of free sugars, the latest scientific evidence on dental caries, recommendations from WHO on sugar-sweetened beverage taxes, nutrition labeling, advertising, food reform, adjusting supply systems, education, and promotion strategies, as well as sugar reduction actions taken by various governments around the world. Combining the actual situation in China, policy recommendations and authoritative popular science knowledge on sugar reduction for caries prevention to public are proposed to advocate for experts in multiple fields to focus on sugar reduction for caries prevention, promote the work process, and provide the scientific basis for oral health educators.

Objective To explore the relationship between triglyceride-glucose index(TyG)and acute ischemic stroke with large vessel occlusion(AIS-LVO)of anterior circulation.Methods A retrospective study was conducted on patients with anterior circulation AIS-LVO who underwent emergency endovascular thrombectomy at Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2019.According to modified Rankin scale(mRS)score 90 d after operation,the patients were assigned to favorable outcome group(mRS score 0-2)or unfavorable outcome group(mRS score 3-6),and the TyG was compared.According to the median of TyG,the patients were assigned to low-TyG group(TyG＜8.57)or high-TyG group(TyG ≥8.57),and the clinical data,laboratory indexes,and imaging characteristics were compared.Receiver operating characteristic curve was used to evaluate the predictive value of TyG for poor prognosis.Results A total of 135 patients were enrolled,with 72 in the favorable outcome group and 63 in the unfavorable outcome group.The TyG of the unfavorable outcome group was significantly higher than that of the favorable outcome group(8.82+0.63 vs 8.43+0.60,P＜0.001).There were 67 patients in the low-TyG group and 68 in the high-TyG group.Compared with the low-TyG group,the proportion of patients with hyperlipidemia history(P=0.003),systolic blood pressure at admission(P=0.018),fasting blood glucose level(P＜0.001),and triglyceride level(P＜0.001)were significantly higher in the high-TyG group,the infarct core volume was significantly larger(P=0.025),the high density lipoprotein-cholesterol level was significantly lower(P=0.013),and the mRS score 90 d after operation was significantly higher(3[1,5]vs 1[0,5],P=0.049).The TyG had certain predictive value for poor prognosis in anterior circulation AIS-LVO patients(area under curve value=0.662,95％confidence interval 0.571-0.753).Conclusion TyG is elevated in anterior circulation AIS-LVO patients with poor prognosis,and may be a potential prognostic indicator for anterior circulation AIS-LVO patients.

Objective:To observe the clinical efficacy of unilateral biportal endoscopy (UBE) assisted bilateral decompression in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side.Methods:A total of 20 patients with lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side treated with UBE from January 2022 to January 2024 in the Affiliated Hospital of Binzhou Medical University were retrospectively analyzed. There were 9 males and 11 females, aged 50.4±14.0 years (range, 23-72 years). The intervertebral disc herniation level included L 3-4 in 1 case, L 4-5 in 15 cases, and L 5S 1 in 4 cases. There were 10 cases on the left side and 10 cases on the right side. The duration of symptoms was 24.1±33.7 months (range, 1-120 months). Visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate postoperative pain relief and functional recovery. The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Results:All patients successfully completed the operation. The operation time was 90.3±24.6 min (range, 55-134 mins). The VAS scores of patients at 3 days, 1 month, 3 months and 6 months after operation were 3.6±0.9, 2.2±0.7, 1.2±0.5 and 1.0±0.6, respectively, which were lower than those before operation (6.4±0.8), and the differences were statistically significant ( F=668.728, P<0.001). The ODI at 3 days, 1 month, 3 months and 6 months after operation were 34.2%±4.7%, 28.7%±2.8%, 24.3%±2.1% and 20.5%±2.0%, respectively, which were lower than 69.4%±5.2% before operation, and the differences were statistically significant ( F=515.578, P<0.001). The clinical efficacy was evaluated by modified MacNab criteria at 6 months after operation. Among 20 patients, 18 cases were excellent, 1 case was good, and 1 case was fair. All patients were followed up for 9.1±2.1 months (range, 6-14 months). One patient had a dural tear during the operation, but the range was small and there was no defect, and no further treatment was performed. Numbness of the lower limbs occurred 1 day after operation, and the symptoms disappeared after symptomatic treatment. There was no recurrence of lower limb symptoms, lumbar instability, intervertebral space infection or other complications at the last follow-up. Conclusion:Bilateral decompression with UBE is effective in the treatment of lumbar disc herniation with imaging herniation on one side and clinical symptoms on the contralateral side, which can improve the lumbar pain and function of patients.

Purpose This study aims to explore the effect of peroxisomal membrane protein 4(PXMP4)on the migration and invasion of cervical cancer(CC)cells,as well as the epithelial-mesenchymal transition(EMT)process.Methods Bioinformatics and immunohistochemical analysis were employed to examine the expression of PXMP4 in CC tissues and its correlation with clinical pathological characteristics.Western blot and RT-qPCR were used to detect the expression of PXMP4 in CC cells.CCK-8 assay,scratch healing assay,and Transwell invasion assay were utilized to assess the proliferation,migration,and invasion capabilities of CC cells.Western blot was conducted to measure the expression of N-cadherin,E-cadherin,vimentin,phosphorylated ERK(p-ERK),and total ERK proteins in cervical CC.Results The TCGA database showed that the mRNA expression level of PXMP4 was significantly elevated in non-paired CC tissues(P=0.000 29),while the GEO database showed that the mRNA expression level of PXMP4 was sig-nificantly elevated in paired CC tissues(P=0.02).Immunohistochemical analysis showed that PXMP4 was primarily localized in the cytoplasm and cell membrane,with a positive rate of 70.31％(45/64)in CC tissues,significantly higher than 29.69％(19/64)in adjacent tissues.Clinical pathological analysis found that PXMP4 expression was as-sociated with maximum tumor differentiation(P=0.000 328)and lymph node metastasis(P=0.000 226),but not with age(P=0.637)or tumor diameter(P=0.304).CCK-8 assay,wound healing assay,and Transwell invasion as-say demonstrated that interference with PXMP4 inhibited the proliferation,invasion,and migration of CC cells,while overexpression of PXMP4 promoted these processes.Western blot results indicated that interference with PXMP4 signif-icantly increased E-cadherin expression and decreased N-cadherin,vimentin,and p-ERK expression(P＜0.05).Conversely,overexpression of PXMP4 led to a significant decrease in E-cadherin and an increase in N-cadherin,vim-entin,and p-ERK expression(P＜0.05).Additionally,stimulation of CC cells with different concentrations of the U0126 inhibitor significantly increased E-cadherin expression and decreased N-cadherin,vimentin,and p-ERK expres-sion(P＜0.05).Conclusion PXMP4 is highly expressed in CC tissues and is closely related to tumor differentiation and lymph node metastasis.PXMP4 promotes the EMT process of CC cells through the phosphorylated ERK1/2 signa-ling pathway.
