In recent years, the prevalence of myopia has continued to rise, with an expanding affected population, making it a significant public health challenge both in China and globally. Elongation of the axial length in myopic eyes can induce a series of pathological changes in intraocular structure and function, increasing the risk of blinding ocular diseases such as retinal pathologies. Since myopia is difficult to reverse once established, scientific intervention is necessary to control its progression and reduce the likelihood of ocular complications. As a current research focus in myopia control, the clinical application of orthokeratology lenses has attracted considerable attention. This article highlights that orthokeratology lenses, worn overnight, reshape the corneal curvature and create a myopic defocus signal in the peripheral retina. This mechanism effectively inhibits excessive axial elongation and slows myopia progression. Clinical evidence indicates that orthokeratology can reduce axial elongation by 30% to 50%, accompanied by a short-term increase in choroidal thickness. This article also analyzes the advantages and limitations of orthokeratology and explores its potential synergistic effects when combined with other interventions such as low-dose atropine. The aim is to provide key theoretical and practical references for clinical myopia control.

ObjectiveTo explore the complex network relationships among pain, kinesiophobia, social participation and knee function in patients after total knee arthroplasty (TKA), and to analyze the moderating effects of different socio-structural factors on the rehabilitation network from an ethical equity perspective. MethodsA convenience sampling method was used to select 291 patients who underwent TKA in Qilu Hospital of Shandong University from May to July, 2023. Pain was assessed using Numerical Rating Scale, kinesiophobia with Chinese short version of the Tampa Scale for Kinesiophobia, social participation with Impact on Participation and Autonomy Questionnaire, and knee function with Hospital for Special Surgery Knee Score. A partial correlation network among pain, kinesiophobia, social participation and knee function was constructed using Graphical Least Absolute Shrinkage and Selection Operator. Key variables were identified through node centrality and bridge centrality analysis. Network Comparison Tests (NCT) were used to analyze network differences among subgroups based on different socio-structural characteristics. ResultsIn the network model, the nodes with the highest strength centrality were indoor participation, activity behavior and activity pain. Bridge centrality analysis indicated that activity pain, knee function, indoor participation and activity cognition were key bridge nodes. NCT revealed no significant differences in overall network structure or global strength among subgroups based on residence, education level or payment method (P > 0.05). However, significant differences in edge weights were found for specific edges such as activity cognition-activity behavior and knee function-indoor participation (P < 0.05). ConclusionThere is a network of interactions among pain, kinesiophobia, social participation and knee function in patients after TKA, with nodes such as indoor participation and activity pain playing key roles in the rehabilitation process. Although the overall rehabilitation network is similar across different socio-structural groups, variations exist in specific relational pathways among patients from rural areas, those with lower education levels, and those with out-of-pocket payment. This suggests that clinical rehabilitation interventions should focus on these core nodes and implement targeted support strategies for socio-structurally disadvantaged groups to promote rehabilitation equity.

Objective To preliminary explore the imaging manifestations of digital breast tomosynthesis (DBT) and contrast-enhanced mammography (CEM) in triple-negative breast cancer (TNBC) patients with different levels of human epidermal growth factor receptor 2 (HER2) expression. Methods A retrospective analysis was conducted on TNBC patients who underwent preoperative DBT or CEM examinations at Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2019 and Shanghai Second People’s Hospital from January 2022 to May 2025. Clinical data, pathological and immunohistochemical results, and imaging data were collected. Results A total of 69 TNBC patients pathologically confirmed as invasive ductal carcinoma were included, among which 34 underwent DBT and 35 underwent CEM. Among these patients, 34 (49.28%) had HER2-low expression and 35 (50.72%) had HER2-zero expression. DBT results showed that the proportion of spiculation signs in HER2-low group (n＝14) was significantly higher than that in HER2-zero group (n＝20; P＝0.009, P_adj＝0.045). However, there were no significant differences in breast density type, mass shape, or calcification between the two groups. CEM results showed that on low-energy images, the proportion of spiculation signs in the HER2-low group (n＝20) was higher than that in the HER2-zero group (n＝15; P＝0.011, P_adj＝0.077). Results of CEM showed that on reconstructed images, differences in background parenchymal enhancement and mass enhancement patterns between the two groups were not statistically significant; in both groups, heterogeneous enhancement was the most common, followed by homogeneous enhancement, with ring enhancement being the least common. Conclusions TNBC with low HER2 expression and TNBC with zero HER2 expression may have potential differences in the presentation of spiculation signs on DBT. However, the correlation between CEM manifestations and TNBC with different HER2 expression levels requires further research.

With the rapid development of artificial intelligence （AI） technology， the ethical governance of AI has gained increasing attention. The Recommendation on the Ethics of Artificial Intelligence was issued by the United Nations Educational， Scientific and Cultural Organization in 2021， which clarified several principles for the ethical governance of AI. In the field of rehabilitation medicine， the research and application of AI technology have significantly improved patients’ quality of life and survival. However， due to the specificity of the service population in rehabilitation medicine， which is mostly for the sick， injured， disabled， and elderly， a series of complex ethical issues have also arisen. This paper analyzed in detail the ethical issues and challenges encountered in the research and application of AI technology in the field of rehabilitation medicine from various aspects， such as informed consent， security of privacy and data， patients’ physical and mental rehabilitation， compliance regulation， protection of specific groups， and promotion of equity. According to the principles of the Recommendation on the Ethics of Artificial Intelligence and others， response strategies were proposed， including multi-party collaboration and interdisciplinary cooperation， improving and refining relevant laws and regulations， strengthening ethical education across society， establishing accountability mechanisms， increasing investment， promoting equity， and other measures， to promote the healthy development of research and application of AI technology in the field of rehabilitation， as well as benefit humanity.

Objective:To analyze the current status and trend of the mortality burden of cardiovascular disease in China from 2010 to 2021.Methods:Data related to cardiovascular disease mortality and disability-adjusted life year (DALY) were extracted from the Global Burden of Disease Study 2021 (GBD2021) database. The age-standardized mortality rate and DALY rate were calculated, using the 2021 world standard population estimated by GBD2021. Joinpoint 5.2.0 software was used to calculate the mortality rate, standardized mortality rate, DALY rate, standardized DALY rate, annual percent change (APC), average annual percent change (AAPC), and 95% CI of cardiovascular disease in China from 2010 to 2021. Results:The mortality rate of cardiovascular disease was 357.44/100 000, and the age-standardized mortality rate was 280.11/100 000 in China in 2021. The DALY rate was 7 043.33/100 000, and the age-standardized DALY rate was 5 120.06/100 000. From 2010 to 2021, the mortality rate and DALY rate of cardiovascular disease in China showed an upward trend (AAPC was 1.58% and 0.83%, respectively, both P<0.05), and the standardized mortality rate and standardized DALY rate showed a downward trend (AAPC was -2.13% and -2.02%, respectively, both P<0.05). The mortality burden of cardiovascular disease was higher in males (mortality rate 392.80/100 000, DALY rate 8 156.19/100 000) than in females (mortality rate 320.38/100 000, DALY rate 5 876.87/100 000). With the increase older in age, the mortality burden of cardiovascular disease in China decreased first and then increased. China ranked high in the mortality burden of cardiovascular disease among G20 member countries. Conclusions:The death burden of cardiovascular disease is serious in China. The mortality rate and DALY rate of cardiovascular disease in China showed an increasing trend from 2010 to 2021, and the standardized mortality rate and standardized DALY rate of cardiovascular disease ranked high in G20 member countries. The death burden of cardiovascular disease was more serious in men and the elderly. It is necessary to develop more comprehensive prevention, treatment, and rehabilitation measures for men and the elderly to reduce mortality and disability rates, decrease the disease burden, and improve the quality of life.

Objective:To observe and analyze the correlations between aqueous humor cytokine concentrations and disorganization of retinal inner layers (DRIL), as well as postoperative visual acuity, in patients with idiopathic epiretinal membrane (iERM).Methods:A prospective clinical study. From November 2022 to October 2024, 40 eyes of 40 patients diagnosed with iERM at Ophthalmology Center of Zhejiang Provincial People's Hospital (Affiliated People's Hospital) underwent cataract surgery alone or combined with pars plana vitrectomy (iERM group) were enrolled; 19 eyes of 19 patients undergoing cataract surgery alone during the same period served as the control group. All eyes underwent best-corrected visual acuity (BCVA) testing and swept-source optical coherence tomography (SS-OCT). BCVA was assessed using a logarithmic visual acuity chart and converted to the logarithm of the minimum angle of resolution (logMAR) for statistical analysis. Central macular thickness (CMT) was measured using SS-OCT. The iERM group was further subdivided into DRIL-positive and DRIL-negative subgroups (21 eyes and 19 eyes, respectively), based on the presence or absence of DRIL. Aqueous humor samples were collected preoperatively from eyes in both the iERM and control groups. Concentrations of transforming growth factor (TGF)-β1, TGF-β2, TGF-β3, platelet-derived growth factor (PDGF)-AB, hepatocyte growth factor, fibroblast growth factor, vascular endothelial growth factor-A (VEGF-A), placental growth factor (PLGF), glial cell line-derived neurotrophic factor (GDNF), intercellular adhesion molecule-1 (ICAM-1), angiopoietin (Ang)-1, Ang-2, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were measured. Follow-up examinations using the same equipment and methods were performed at 1 month postoperatively. Aqueous cytokine levels were compared between the iERM group, control group, DRIL-positive subgroup, and DRIL-negative subgroup. Correlations between aqueous cytokine levels in the iERM group and BCVA or CMT were also analyzed. Intergroup comparisons utilized the Mann-Whitney U test; correlations between variables were assessed using Spearman's rank correlation analysis. Results:Compared to the control group, the iERM group exhibited significantly higher aqueous concentrations of TGF-β1, TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, and TNF-α ( P<0.05). Compared to the DRIL-negative subgroup, the DRIL-positive subgroup showed significantly elevated aqueous concentrations of TGF-β3, PDGF-AB, PLGF, GDNF, ICAM-1, Ang-1, Ang-2, TNF-α, and IL-6 ( P<0.05). Significant differences were observed in logMAR BCVA ( P=0.028) and CMT ( P<0.001) within the iERM group between preoperative and 1-month postoperative measurements. LogMAR BCVA differed significantly between the DRIL-positive and DRIL-negative subgroups ( P=0.048). Correlation analysis revealed that baseline aqueous levels of VEGF-A and IL-6 in eyes with DRIL were positively correlated with postoperative BCVA ( r=0.324, 0.452; P=0.042, 0.003). No significant correlation was found between CMT and any cytokine ( P>0.05). Conclusions:Aqueous humor cytokines are closely associated with DRIL in iERM patients. IL-6 and VEGF-A may serve as potential predictive biomarkers for early postoperative visual recovery.

Objective:To assess the clinical outcomes of dual-approach bicondylar fixation under adjustable positioning for Schatzker type IV trans-midline tibial plateau fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 52 patients with Schatzker type IV trans-midline tibial plateau fractures admitted to First Affiliated Hospital to Nanjing Medical University from January 2014 to August 2023, including 37 males and 15 females, aged 19-68 years [(42.3±14.0)years]. All the patients were treated with the surgical scheme of anterior and medial dual-approach bicondylar internal fixation under adjustable positioning. The operation duration, intraoperative blood loss, and fracture healing time were counted. X-ray films were reviewed at 2 days after surgery for residual knee subluxation. At 2 days, 3 and 6 months after surgery, and at the last follow-up, the tibial plateau angle (TPA) and posterior slope angle (PA) were measured with follow-up X-ray films to evaluate whether there was loss of reduction. The knee function was evaluated with the American Hospital for Special Surgery (HSS) knee function score at 3 and 6 months after surgery and at the last follow-up. The anterior posterior displacement and rotation stability of the knee were evaluated with Lachman test and pivot-shift test at the last follow-up. The postoperative complications were recorded.Results:All the patients were followed up for 12-118 months [70(46, 85)months]. The operation duration was 100-180 minutes [145(120, 160)minutes], with intraoperative blood loss of 100-550 ml [(323.8±135.1)ml]. Fractures were healed well in all the patients, with the healing time of 2-4 months [3.0(2.4, 3.5)months]. None of the patients had residual subluxation by X-ray films at 2 days after surgery. There were no significant differences in TPA or PA at each time point after surgery ( P>0.05). The HSS knee function score was (69.4±4.9)points, (80.9±7.0)points, and (90.1±7.9)points at 3 and 6 months after surgery and at the last follow-up, respectively and the score gradually increased with the passage of time ( P<0.05). At the last follow-up, all the patients were negative in Lachman test and pivot-shift test. Three patients developed fat liquefaction around medial wounds after surgery, which were healed after dressing change. While the wounds were healed by first intention in the other patients. Postoperative complications such as knee instability, implant loosening, fracture or refracture not occurred. Conclusion:Dual-approach bicondylar fixation under adjustable positioning for Schatzker type IV trans-midline tibial plateau fractures has the advantages including high fracture healing rate, precise fracture reduction and fixation, satisfactory postoperative functional recovery and fewer complications, without increasing operation duration or intraoperative blood loss.

Objective To explore the lung protective effect of pressure controlled ventilation-volume guaranteed(PCV-VG)combined with driving pressure(DP)guided lung protective ventilation strategy in patients undergoing thoracoscopic and laparoscopic radical esophagectomy.Methods 70 patients scheduled for elective thoracoscopic and laparoscopic radical esophagectomy were allocated into two groups using a random number table method:Conventional lung protective ventilation strategy group(group C)and DP guided lung protective ventilation strategy under PCV-VG mode group(group P),35 case in each group.Peak airway pressure(Ppeak),plateau pressure(Pplat),dynamic compliance(Cdyn)and DP were compared between the two groups at 5 minutes after intubation(T1),30 min after pneumoperitoneum established(T2),just prior to one lung ventilation(OLV)(T3),30 min after OLV(T4),60 min after OLV(T5)and 15 min from recovery of two lung ventilation(TLV)(T6).The blood pressure(BP),heart rate(HR),arterial partial pressure of oxygen(PaO2),partial pressure of carbon dioxide in arterial blood(PaCO2)and pH were recorded before anesthesia(T0),T2,T3,T4,T5 and T6 time points.The occurrence of postoperative pulmonary complications(PPCs)also recorded.Results Compared with group C,Ppeak in group P at T1,T2,T4,T5 and T6 time points was significantly decreased,and Cdyn was obviously increased,the differences were statistically significant(P＜0.05).At the T1,T4,T5 and T6 time points,the DP was lower in group P compared to group C,and Pplat at T6 time point was lower than that in group C,the differences were statistically significant(P＜0.05).At the time points of T4 and T5,the PaO2 in group P was higher than that in Group C,and the PaCO2 at T6 time point was also higher than that in group C,the differences were statistically significant(P＜0.05).The comparison of PaCO2 at T0,T2,T3,T4 and T5 time points of the two groups,the difference was not statistically significant(P＞0.05).Comparison of pH between the two groups,the difference was not statistically significant at all time points(P＞0.05).The systolic blood pressure(SBP)of group P was higher than that of group C at the T4 time point,and the diastolic blood pressure(DBP)was lower than that of group C at T6 time point,and the differences were statistically significant(P＜0.05);There were no significant differences in SBP and DBP at T0,T2,T3 and T5 time points,and HR at each time point between the two groups(P＞0.05).There was no statistically significant difference in the occurrence of PPCs within 7 d after operation between the two groups(P＞0.05).Conclusion DP guided lung protective ventilation strategy under PCV-VG mode can improve intraoperative respiratory mechanics,and increase oxygenation during OLV in patients undergoing thoracoscopic and laparoscopic radical esophagectomy,but it does not significantly affect the incidence of PPCs within 7 d after operation.It is worthy clinical significant.
