Macular hole is an age-related disorder defined by a full-thickness defect of the foveal retina and a profound loss of central vision. First described in the mid-19th century, its study has now extended across more than 150 years. Breakthroughs in science and technology—especially the relentless refinement of retinal imaging platforms—have progressively refined our understanding of the disease. Optical coherence tomography(OCT)in particular has revolutionized characterization of the condition. At the same time, the widespread adoption of macular hole surgery has not only driven deeper investigations into pathogenesis and pre-operative assessment but also facilitated the global dissemination of surgical expertise and a marked rise in anatomical success. This review synthesizes the multimodal imaging hallmarks of macular holes and highlights the remaining clinical challenges in the application of OCT technology.

BACKGROUND: The incidence and mortality rates of lung cancer remain on the rise, creating an urgent need for screening among high-risk populations and early prevention. This study aims to explore the association and interaction between multidimensional lifestyle, socioeconomic status, and the incidence of lung cancer, and to provide scientific evidence for screening high-risk populations and preventing lung cancer. METHODS: Healthy lifestyle score was constructed using information on smoking, alcohol consumption, exercise, diet and sleep obtained through a questionnaire survey. Socioeconomic status was evaluated based on information on education, employment, and family income, and genetic testing data were used to assess the risk of genetic variation. A proportional hazards assumption test was conducted, and the Cox proportional hazards model was applied to analyze the associations between healthy lifestyle scores, socioeconomic status, and lung cancer, as well as the interactions among various factors, after adjusting for the risk of genetic variation, age, gender, diabetes, hypertension and the living environment score. RESULTS: A total of 245,538 samples that entered the cohort from March, 2006 to October, 2010 were included and followed up until December 31, 2022. The participants were divided into the case group (n=1472) and the control group (n=244,066). The analysis results showed that after adjusting for covariates, there was still an association between the healthy lifestyle score, socioeconomic status, and the incidence of lung cancer: compared with participants with a high healthy lifestyle score, the risk of lung cancer in participants with medium and low healthy lifestyle scores was significantly increased, with hazard ratios (HR) of 2.12 (95%CI: 1.86-2.41) and 3.36 (95%CI: 2.82-3.99) respectively; compared with participants with high socioeconomic status, the risk of lung cancer in participants with medium and low socioeconomic status was significantly increased, with HR of 1.29 (95%CI: 1.13-1.48) and 1.67 (95%CI: 1.46-1.90) respectively. Moreover, there were interactions between smoking status and socioeconomic status (Pfor interaction=0.05), as well as the other four lifestyle factors (Pfor interaction=0.02). CONCLUSIONS This study identified the association between multidimensional lifestyle factors and socioeconomic status with the incidence of lung cancer, as well as interactions between smoking and socioeconomic status and four other lifestyle factors, providing a scientific basis for screening and prevention in high-risk populations for lung cancer.

Objective:To investigate the clinical value of ultrasonography combined with serum thyroglobulin (Tg) levels in preoperative N staging and therapeutic effect evaluation in patients with thyroid cancer.Methods:A retrospective analysis was conducted on the clinical data of 125 patients with thyroid cancer who underwent total thyroidectomy at The 903 Hospital of PLA Joint Logistics Support Force between January 2016 and December 2021. Based on the pathological results, the patients were divided into stages N0, N1a, and N1b. Consistency testing was performed to assess the consistency between ultrasonographic and pathological findings. The serological markers were compared between stage N0 and stage N1. A multivariate logistic regression analysis was conducted to investigate the correlation between antithyroid peroxidase antibodies (TPOAb) and Tg and lymph node metastasis. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of serum Tg, ultrasonography, and the combination of serum Tg with ultrasonography for lymph node metastasis.Results:Among the 125 patients, 51 cases were diagnosed with stage N1, including 36 cases of stage N1a and 15 cases of stage N1b. The pathological examination confirmed stage N0 in 74 cases. Ultrasonography results showed stage N0 in 96 cases, stage N1a in 7 cases, and stage N1b in 22 cases. The preoperative N staging of thyroid cancer patients by ultrasonography was moderately consistent with the pathological staging ( Kappa = 0.44, P < 0.001). Serum free triiodothyronine and Tg levels were higher in stage N1 compared with stage N0 ( P < 0.001), while serum TPOAb levels were lower in stage N1 than in stage N0 ( P = 0.017). Multivariate logistic regression analysis was performed with lymph node metastasis as the dependent variable and the factors FT3, TPOAb, and Tg levels as independent variables. The analysis revealed that Tg was associated with lymph node metastasis ( OR = 1.02, P < 0.001). The ROC curve analysis showed that the area under the ROC curve for serum Tg level and ultrasonography for the diagnosis of lymph node metastasis were 0.67 and 0.65, respectively, which were significantly lower than the area under the curve (0.76) for the combined detection ( P < 0.001). Conclusion:The combined utilization of ultrasonography and serum Tg levels in the preoperative staging of thyroid cancer patients holds distinct clinical relevance. Notably, this combined approach offers a more precise diagnosis of lymph node metastasis compared with ultrasonography alone. Consequently, when making clinical judgments regarding preoperative lymph node metastasis, it is advisable to consider the results of both ultrasonography and serum Tg testing to facilitate surgical planning and evaluate surgical outcomes.

Objective:To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD) accompanied with sleep disorder.Methods:PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group (PD-SD group) ( n=56) and PD without sleep disorder group (PD-NSD group) ( n=41) according to the Parkinson's disease sleep scale (PDSS) score. All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS, Hoehn-Yahr (H-Y), Montreal cognitive assessment scale (MoCA), and cholinergic pathways hyper intensities scale (CHIPS). The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test, Spearman correlation analysis, and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software. Results:(1)The MoCA score of the PD-SD group (22.00 (5.00)) was lower than that of the PD-NSD group (26.00 (5.00)) ( Z=-3.830, P<0.05). The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule: 12.00(8.00), 0(8.00), the total score of the high external capsule: 12.00(2.00), 6.00(9.00), the total score of the radial crown: 8.00(0), 4.00(4.00), the total score of the centrum semiovale: 3.00(4.00), 0(2.00), the total score of the right side: 16.00(9.00), 5.00(10.00), the total score of the left side: 17.00(6.00), 7.00(9.00), the total score of CHIPS: 32.00(14.00), 14.00(20.00))( Z=-5.081, -5.873, -4.933, -3.211, -5.562, -6.232, -5.995, all P<0.05). (2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that, the total score of the low external capsule ( r=-0.286), the total score of the centrum semiovale ( r=-0.307), the total score of the right side ( r=-0.376), the total score of the left side ( r=-0.284) and the total score of CHIPS ( r=-0.349) were negatively correlated with MoCA(all P<0.05). (3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale, low inner capsule, right and left leukodystrophy were not influence factors for cognitive impairment (all P>0.05). Conclusion:PD patients with sleep disorders have lower cognitive function scores, higher CHIPS scores, and significant changes in white matter lesions compared to those without sleep disorders. In PD patients with sleep disorders, the higher the CHIPS score, the lower the cognitive function score, and the more significant the rate of cognitive impairment occurrence and development.

Conclusion:MSE has a protective effect on chronic chemically-induced liver injury induced by ethanol, APAP, and CCl 4 in mice, and its mechanism may be related to antioxidant stress, inhibition of inflammatory response, and regulation of the expression of cytochrome P450-related enzymes.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective:To investigate the serum levels of myonectin, corticostatin and Delta like ligand 4 (DLL4) in patients with type 2 diabetes mellitus (T2DM) diabetes retinopathy (DR) and their clinical significance.Methods:A prospective selection of 341 T2DM patients admitted to Beijing Hospital of Traditional Chinese Medicine, Huairou Hospital from May 2020 to March 2022 was conducted. The patients underwent fundus examination and were divided into a non DR group ( n=85 cases) and a DR group ( n=256 cases) based on DR diagnostic criteria. The DR group was divided into non proliferative and proliferative types according to the staging criteria in China′s DR clinical diagnosis and treatment guidelines, with 142 cases and 114 cases, respectively; 190 healthy individuals who underwent physical examinations in our hospital during the same period were selected as the control group. Enzyme linked immunosorbent assay was used to detect the levels of serum sarconectin, corticostatin, and DLL4 in three groups, collect patient data, and detect biochemical indicators. Logistic regression analysis was used to analyze the influencing factors of DR, and Pearson correlation analysis was used to investigate the relationship between serum sarconectin, corticostatin, DLL4, glucose and lipid metabolism, and insulin resistance; Logistic regression analysis was used to analyze the influencing factors of DR, and Pearson correlation analysis was used to investigate the relationship between serum sarconectin, corticostatin, DLL4, glucose and lipid metabolism, and insulin resistance; The receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of serum sarconectin, corticostatin, and DLL4 in DR. Results:The levels of serum sarconectin and DLL4 in the DR group and non DR group were higher than those in the control group, while the levels of corticostatin were lower than those in the control group (all P<0.05); The levels of sarconectin and DLL4 in the DR group were higher than those in the non DR group, while the levels of corticostatin were lower than those in the non DR group (all P<0.05). The serum levels of sarconectin and DLL4 in proliferative DR patients were higher than those in non proliferative DR patients, while the levels of corticostatin were lower than those in non proliferative DR patients (all P<0.05). The duration of T2DM in the DR group was longer than that in the non DR group, with smoking and alcohol consumption, systolic blood pressure, fasting blood glucose, glycated hemoglobin, triglyceride and insulin resistance index (HOMA-IR) were higher than those in non DR group (all P<0.05). Logistic regression analysis showed that the course of T2DM, systolic blood pressure, smoking and alcohol consumption, glycated hemoglobin, triglycerides, myonectin, corticostatin and DLL4 were the influencing factors of DR (all P<0.05). Pearson correlation analysis results showed that serum sarconectin, DLL4, and fasting blood glucose, glycated hemoglobin, fasting insulin and HOMA-IR were positively correlated (all P<0.05), while cortisol was negatively correlated with fasting blood glucose, glycated hemoglobin and HOMA-IR (all P<0.05). The ROC analysis results showed that the area under the curve (AUC) for the diagnosis of DR was 0.691, 0.745, 0.749, and 0.861 for sarconectin, corticostatin, and DLL4 alone and in combination, respectively. The combined application had higher diagnostic value. Conclusions:Patients with T2DM complicated with DR have elevated levels of serum sarconectin and DLL4, while decreased levels of corticostatin, which are closely related to glucose and lipid metabolism and insulin resistance, and are influencing factors for the occurrence of DR. Combined detection of the three can improve the value of predicting DR.
