AIM: To explore the control effects of wearing orthokeratology lens for 1 a on adolescent myopia patients with different diopters.METHODS: Prospective non-randomized controlled study. A total of 120 adolescent myopic patients(224 eyes), with an average age of 11.00±2.08 years old, who were fitted with orthokeratology lenses in the optometry department of our hospital from November 2022 to May 2023 were collected. There were 3 groups according to the spherical equivalent, including 86 eyes in the group of -0.50--2.00 D, 99 eyes in the group -2.25--4.00 D, and 39 eyes in group -4.25--6.00 D. Patients were followed up for 1 a to observe the changes of uncorrected visual acuity, axial length, corneal curvature, corneal central thickness and corneal endothelial cells density in the three groups after wearing lens for 1 a.RESULTS:A total of 113 cases(212 eyes)were followed up for 1 a, including 82 eyes in the group of -0.50--2.00 D, 95 eyes in the group of -2.25--4.00 D, and 35 eyes in the group of -4.25--6.00 D. There was no statistical difference in corneal central thickness and corneal endothelial cell density among the three groups of patients after wearing lens for 1 a(all P>0.05). Uncorrected visual acuity was significantly improved, and flat kerotometry(FK)and steep kerotometry(SK)were significantly flatter(both P<0.01). Furthermore, the growth of axial length in the three groups of patients after wearing lens for 1 a was 0.21±0.26, 0.13±0.21 and 0.09±0.10 mm, respectively(P<0.05). There were differences between the -0.50--2.00 D group and the -2.25--4.00 D group and -4.25--6.00 D group(P=0.028, 0.010), and there were no differences between the -2.25--4.00 D group and the -4.25--6.00 D group(P=0.344).CONCLUSION:It is safe and effective for young myopia patients to wear orthokeratology lenses, which can prevent the non-benign growth of the axial length and effectively delay the development of myopia, and the myopia control effect is better especially for myopia patients of above -2.0 D.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

Traditional Chinese medicine(TCM)serves as a treasure trove of ancient knowledge,holding a crucial position in the medical field.However,the exploration of TCM's extensive information has been hindered by challenges related to data standardization,completeness,and accuracy,primarily due to the decen-tralized distribution of TCM resources.To address these issues,we developed a platform for TCM knowledge discovery(TCMKD,https://cbcb.cdutcm.edu.cn/TCMKD/).Seven types of data,including syndromes,formulas,Chinese patent drugs(CPDs),Chinese medicinal materials(CMMs),ingredients,targets,and diseases,were manually proofread and consolidated within TCMKD.To strengthen the integration of TCM with modern medicine,TCMKD employs analytical methods such as TCM data mining,enrichment analysis,and network localization and separation.These tools help elucidate the molecular-level commonalities between TCM and contemporary scientific insights.In addition to its analytical capabilities,a quick question and answer(Q&A)system is also embedded within TCMKD to query the database efficiently,thereby improving the interactivity of the platform.The platform also provides a TCM text annotation tool,offering a simple and efficient method for TCM text mining.Overall,TCMKD not only has the potential to become a pivotal repository for TCM,delving into the pharmaco-logical foundations of TCM treatments,but its flexible embedded tools and algorithms can also be applied to the study of other traditional medical systems,extending beyond just TCM.

Objective:To evaluate the predictive value of simplified geriatric assessment (sGA) in elderly Chinese patients diagnosed with diffuse large B-cell lymphoma (DLBCL) .Methods:It retrospectively analyzed the relationships of sGA with the clinical characteristics, outcome, and prognosis of 219 patients aged ≥60 years who were newly diagnosed with DLBCL at six hospitals in Jiangsu province between January 2018 and December 2022.Results:The median age of 219 patients was 68 years (60-87 years). According to the sGA system criteria, 101 (46.1%), 103 (47.0%), and 15 (6.8%) elderly patients with DLBCL were categorized as fit, unfit, and frail, respectively. The most common adverse reactions after chemotherapy were hematologic, and the incidence of grade >2 hematologic adverse reactions was similar among the three groups (47.5% vs 41.7% vs 46.7%, respectively; χ2=0.712, P=0.700). Compared with the fit and unfit groups, the frail group showed tendencies toward for higher proportions of grade >2 gastrointestinal, pulmonary, and infectious adverse reactions ( P>0.05 for all). The fit, unfit, and frail groups had respective remission rates of 74.3%, 46.6%, and 20.0% ( χ2=25.249, P<0.001) ; disease progression rates of 5.9%, 11.7%, and 26.7% ( χ2=6.763, P<0.05) ; 2-year overall survival rates of 92.1% (95% CI 86.6% to 97.9%), 77.6% (95% CI 69.5% to 86.6%), and 70.1% (95% CI 49.4% to 99.6%) ( P<0.05) ; and 2-year progression-free survival rates of 76.8% (95% CI 67.0% to 84.8%), 69.7% (95% CI 61.8% to 82.0%), and 65.7% (95% CI 53.3% to 100%) ( P=0.399) . Conclusion:sGA can effectively predict treatment adverse effects and efficacy, disease progression, and long-term survival in elderly DLBCL.

Objective:To evaluate the clinical prognostic value of intratumoral metabolic heterogeneity parameters of baseline 18F-FDG PET/CT in primary cutaneous malignant melanoma (CMM). Methods:From October 2015 to July 2023, the clinical data of 35 patients (24 males, 11 females, age (66.6±13.1) years) diagnosed with primary CMM who underwent baseline 18F-FDG PET/CT in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were retrospectively analyzed. Conventional metabolic parameters (SUV max, metabolic tumor volume (MTV), total lesion glycolysis (TLG)) and PET intratumoral metabolic heterogeneity parameters (area under the cumulative SUV histograms curve (AUC-CSH), linear regression slope, SUV max/ SUV mean) were assessed. Using thresholds of 30%, 40%, 50%, 60%, 70%, and 80% SUV max or thresholds of 40%, 60%, and 80% SUV max to delineate MTV, linear regression was performed, with the slopes being heterogeneity index-1 (HI-1) and heterogeneity index-2 (HI-2), respectively. Using SUV thresholds of 2.5, and 40%, 50%, 60%, and 70%SUV max to calculate AUC-CSH and SUV max/SUV mean. Kaplan-Meier survival curves and Cox proportional hazards models were used to analyze the prognostic value of primary lesion PET metabolic parameters on overall survival (OS) and progression-free survival (PFS). Results:The median follow-up time of 35 patients was 20 months, with 25 patients (71%) experiencing disease progression and 16 patients (46%) deceased. Multivariate Cox regression analysis revealed that HI-1, HI-2, MTV, SUV max/SUV mean2.5, and SUV max were the independent prognostic factors for PFS (hazard rate ( HR) (95% CI): 0.32(0.13-0.82), 0.32(0.13-0.82), 3.86(1.34-11.12), 4.61(1.33-16.02), 4.06(1.55-10.61), all P<0.05), whereas SUV max and SUV max/SUV mean2.5 were the independent prognostic factors for OS ( HR: 8.04(1.96-32.87), 2.87(1.09-7.51), P values: 0.004, 0.032). Conclusion:HI-1, HI-2, and SUV max/SUV mean2.5 have prognostic value for CMM, while the value of AUC-CSH heterogeneity parameters are not significant.

Objective To construct a discharge preparation plan for patients with head and neck cancer undergo-ing tracheotomy and explore its application effect to provide a reference for improving the at-home self-care ability of tracheostomy patients with head and neck cancer.Methods The discharge preparation plan for patients with head and neck cancer undergoing tracheotomy was constructed through literature analysis and expert consultation.A total of 160 patients with tracheotomy for head and neck cancer who were hospitalized in the Department of Oto-laryngology and Head and Neck Surgery of a tertiary A general hospital in Jinan City,Shandong Province from May 2023 to February 2025 were selected by convenience sampling method as the study subjects,and were divided into an experimental group and a control group by block randomization method,with 80 cases in each group.The ex-perimental group received a discharge preparation plan for patients undergoing tracheotomy for head and neck can-cer,while the control group received routine nursing and health education.Data from admission to 1 month after discharge were collected.The levels of mindfulness awareness,self-care ability,and discharge readiness were compared between 2 groups of patients before and after intervention.Results The constructed discharge preparation plan in-cludes 5 stages(pre-contemplation,contemplation,preparation,action,and maintenance).There were no sample dropouts in either group of patients.The experimental group had higher levels of mindfulness awareness,self-care ability and discharge readiness scores than the control group,and the differences were statistically significant(P＜0.001).Conclusion The discharge preparation plan for patients with head and neck cancer undergoing tra-cheotomy is scientifically reasonable,safe,and feasible,which can effectively improve patients' discharge preparation and mindfulness level,and enhance their self-care ability.

Objective:To investigate the association between peak growth hormone(GH) levels and body fat mass as well as body fat percentage in children with short stature.Methods:This retrospective study included 477 children diagnosed with short stature at the Affiliated Hospital of Jining Medical University between January 2021 and November 2024, based on data from the Growth and Development Disease Follow-up Cohort Study(GDDSD) in Shandong Province. Clinical data including anthropometric measurements, laboratory tests, and body composition were collected. The relationship between GH peak and body fat mass and percentage were analyzed using smooth curve fitting and multiple piecewise linear regression models.Results:In univariate linear regression analysis, both body fat mass and body fat percentage were positively correlated with age, height, weight, body mass index, triglycerides, low density lipoprotein-cholesterol, fasting blood glucose, total body water, protein, and skeletal muscle mass(all P<0.05), and negatively correlated with GH peak and high density lipoprotein-cholesterol. After adjusting for potential confounding factors, a nonlinear relationship was observed between GH peak and both body fat mass and body fat percentage, with inflection points at 6.80 ng/mL and 7.75 ng/mL, respectively. When GH peak was below the inflection point, it was significantly negatively correlated with body fat mass and percentage( P<0.001). However, when GH peak exceeded the inflection point, the associations were no longer statistically significant( P>0.05). Conclusions:This study demonstrates a nonlinear relationship between peak GH levels and body fat percentage in children with short stature. At lower GH peaks, both body fat mass and body fat percentage increase significantly, which may contribute to an elevated future risk of cardiovascular disease.

Objective:To construct and validate a predictive model for postoperative pulmonary complications (PPCs) in patients undergoing robot-assisted laparoscopic urological surgery.Methods:This retrospective study included the medical records of 932 patients who underwent robot-assisted laparoscopic urological surgery at the First Affiliated Hospital of Zhejiang University School of Medicine from January 2020 to February 2022. The patients were divided into a training group ( n=559) and a validation group ( n=373) at a 6∶4 ratio. Logistic regression analysis was used to determine the independent risk factors for PPCs, and a nomogram prediction model was constructed based on these factors. The performance of the model was evaluated using the receiver operating characteristic curve and calibration curve, and the clinical benefit was assessed using the clinical decision curve analysis. Results:The independent risk factors for PPCs included advanced age (>60 yr), smoking history, respiratory tract infection within 1 month, preoperative low SpO 2 (<96%), and prolonged length of postoperative hospital stay ( P<0.05), and the body mass index (18.5-<28.0 kg/m 2) was a protective factor. The nomogram prediction model developed based on the aforementioned 6 influencing factors had an area under the receiver operating characteristic curve of 0.81 (95% confidence interval 0.76-0.86) in training group and 0.80 (95% confidence interval 0.75-0.86) in validation group. The calibration curve indicated a good consistency between the predicted and actual occurrence curves, and the clinical decision curve analysis showed good accuracy and net benefit of the prediction model. Conclusions:The predictive model for PPCs is successfully constructed based on age, low body mass index, smoking history, history of respiratory tract infection within 1 month, preoperative low SpO 2 and prolonged length of postoperative hospital stay and has good predictive performance in patients undergoing robot-assisted laparoscopic urological surgery.

Neurofibromas are benign peripheral nerve sheath tumors. It is more common in neurofibromatosis type Ⅰ. However, isolated vagal nerve neurofibroma（VNN） of the neck is extremely rare, and only a few case reports have been reported. Its etiology and pathogenesis are not clear. The diagnosis is mainly based on pathological examination and immunohistochemistry, and surgical resection is the main treatment. This study reports a rare case of giant solitary vagus neurofibroma in the neck. The patient was a 29-year-old female who was found to have a mass on the right side of the neck by physical examination, which was considered to be a vagus nerve tumor by neck ultrasound and imaging examination. The tumor was completely removed during the operation, with the size of about 10.0 cm×2.5 cm, and the patient had no special discomfort. Postoperative pathology and immunohistochemistry confirmed neurofibroma. After surgery, the patient had right vocal cord paralysis, hoarseness, choking and paroxysmal cough. After swallowing function training and voice rehabilitation treatment in the department, the patient recovered satisfactorily. There was no complication and recurrence during the follow-up of 1 year. This article reviews the literature to improve the diagnosis and treatment of solitary vagus neurofibroma in the neck by combining its medical history, imaging features, pathology and immunohistochemistry, and surgical treatment.
