Dry eye disease is a chronic ocular surface disorder of multifactorial origin, characterized by a loss of tear film homeostasis and associated with a range of ocular discomfort symptoms. Growing evidence underscores a significant bidirectional relationship between dry eye and depression: individuals with dry eye disease exhibit a higher prevalence of depressive disorders, and conversely, those diagnosed with depression demonstrate an increased susceptibility to developing dry eye. This interplay is mediated through several pathophysiological pathways, such as chronic inflammation, cerebral functional alterations, gut microbiome dysregulation, and sleep disturbances, which may collectively sustain a vicious cycle. The use of antidepressant therapy introduces further complexity, exerting heterogeneous effects on dry eye—some agents may offer symptomatic relief, whereas others can aggravate ocular surface impairment. The mechanisms responsible for these differential outcomes remain incompletely elucidated and merit further investigation. This review systematically consolidates epidemiological data on the dry eye-depression link, examines potential shared pathological mechanisms, and evaluates current therapeutic options. We propose an integrated management approach that combines conventional dry eye treatments, such as traditional Chinese medicine, electroacupuncture, physical activity and antidepressants—a multimodal strategy that may yield synergistic benefits in alleviating both ocular and affective symptoms, thereby improving overall quality of life. Moving forward, research should focus on deciphering the underlying mechanistic pathways and facilitating the translation of these insights into clinical practice to inform targeted, combined treatment regimens for patients with dry eye and depression.

Purpose: Alectinib has been approved for anaplastic lymphoma kinase (ALK)–positive non–small cell lung cancer (NSCLC) at 300 mg twice daily in Japan, lower than global standard of 600 mg twice daily. This study evaluated the clinical relevance of the reduced dose by comparing outcomes between the two doses. Materials and Methods: This study included patients with advanced ALK-positive NSCLC who received alectinib at Samsung Medical Center, Korea. The progression-free survival (PFS), overall survival, cumulative incidence of central nervous system (CNS) progression, and safety profiles were retrospectively reviewed and compared. Results: Among 306 patients, 32 and 274 received alectinib at either 300 or 600 mg twice daily, respectively. The 300 mg group showed a slight but not significant advantage in PFS (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.44 to 1.51; p=0.51) and overall survival (HR, 0.51; 95% CI, 0.20 to 1.21; p=0.13). Superior outcome with 300 mg was remarkable in patients with lower body weight (≤ 60 kg), but diminished in patients with higher body weights. Patients with baseline brain metastasis in the 300 mg group exhibited a slight increase in incidence of CNS failure (HR, 1.76; 95% CI, 0.53 to 5.8; p=0.36). Although the safety profiles were mostly mild, adverse events were more frequent in the 600 mg group, 50% of which requiring dose reduction. Conclusion Alectinib at 300 mg twice daily seems an acceptable dose in East Asians with ALK-positive NSCLC. Notably, our data favor 300 mg twice daily in patients with lower body weight and no baseline brain metastasis, considering the more tolerable safety profiles and the potential to reduce medical costs.

Background: The surgical neck of the humerus is located approximately 2–3 cm distal to the anatomical neck (collum anatomicum) at the junction of the greater and lesser tubercles and the humeral shaft. Owing to the transition between cortical and cancellous bones, this region is biomechanically vulnerable and prone to fractures, particularly in older adults. Fractures of the surgical neck of the humerus are classified under the International Classification of Diseases, 10th Revision (ICD-10), with diagnostic codes S42.21.3, S42.22, and S42.23. National statistics indicate that 210,763 new trauma cases were reported in Mongolia in 2023, representing an 11.6% increase compared to the previous year, of which 11,452 cases (5.4%) involved shoulder and humeral injuries. Aim: This study aimed to compare the clinical effects of traditional Mongolian bone-setting therapy and surgical treatment on pain intensity, shoulder function, range of motion, and activities of daily living in patients with surgical neck of the humerus fractures. Materials and Methods: Based on the Department of Traditional Therapies of the Mongolian National University of Medical Sciences (MNUMS) and the Department of Orthopedic Trauma of the Inner Mongolia International Hospital, Inner Mongolia Autonomous Region, China, a total of 60 patients diagnosed with surgical neck fractures of the humerus were enrolled in this study between January 2024 and December 2025. The patients were randomly assigned into two groups: a Mongolian traditional bone-setting therapy group (n=30) and a surgical treatment group (n=30). Assessments were conducted before treatment and at 1 month and 3 months after treatment. Shoulder joint range of motion, activities of daily living, and muscle strength were evaluated using the Constant–Murley score, while pain intensity was assessed using the Visual Analog Scale (VAS). The collected data were systematically analyzed, and the therapeutic outcomes of the two treatment modalities were comprehensively compared and summarized. Result: The baseline demographic and clinical characteristics were comparable between the groups. In the traditional bone-setting group, VAS scores decreased significantly, whereas Constant–Murley scores improved markedly at both follow-up points. The overall outcomes in the traditional bone-setting group were significantly better than those in the surgical group (P<0.05). Conclusion Traditional Mongolian bone-setting therapy offers rapid pain relief, superior long-term functional recovery, and fewer complications, making it a valuable treatment option, particularly for elderly patients and those unsuitable for surgery.

Background: Mongolian traditional bone-setting is a non-surgical treatment method for fractures; however, there is a lack of evidencebased research evaluating its effectiveness, which forms the basis of our study. Aim: To study the therapeutic efficacy of traditional bonesetting treatment for surgical neck fractures of the humerus. Materials and Methods: From June 2023 to June 2025, 120 patients diagnosed with surgical neck fractures of the humerus and treated at the Inner Mongolia International Mongolian Hospital were randomly divided into a traditional bone-setting group (n=64) and a surgical treatment group (n=56). Shoulder and upper limb function were evaluated at 1, 3, and 6 months after treatment using the Constant–Murley score, Oxford Shoulder Score (OSS), and Visual Analog Scale (VAS) for pain. Result: A total of 120 patients with surgical neck fractures of the humerus were divided into two groups, with no significant differences in the baseline characteristics (p>0.05).In the traditional bone-setting group, pain (VAS) decreased more rapidly at 1–3 months (p<0.01), while activities of daily living and functional outcomes improved significantly at 3–6 months (p<0.01). At 6 months, shoulder function (Constant–Murley score) was significantly improved (p=0.049).In contrast, the surgical group showed faster recovery in joint range of motion and muscle strength in the early stage; however, by 6 months, the outcomes between the two groups were comparable. Conclusion In the treatment of surgical neck fractures of the humerus, no significant difference was observed between traditional bone-setting and surgical treatment in terms of shoulder range of motion and muscle strength recovery. However, the advantages of traditional bone-setting lie in its ability to relieve pain more rapidly, promote faster functional recovery, improve activities of daily living, and achieve better long-term outcomes than modern bone-setting. Therefore, traditional bone setting is a safe and effective treatment method that aligns with modern theories of bone healing and rehabilitation principles and holds significant value for wider clinical application and further research in the management of surgical neck fractures of the humerus.

Objective To comparatively analyze the clinical characteristics of primary bilateral macronodular adrenal hyperplasia(PBMAH)and adrenal cortisol-producing Adenoma(CPA),and enhance the understanding of two diseases.Methods The clinical data of 85 PBMAH patients(PBMAH group)and 195 CPA patients(CPA group)diagnosed at Department of Endocrinology,the First Medical Center of Chinese PLA General Hospital,from September 2014 to August 2024 were retrospectively analyzed.The demographic characteristics,comorbidities,biochemical indicators,adrenocorticotropic hormone-cortisol(ACTH-F)levels,and adrenal imaging features and treatment conditions were compared between the two groups.Results(1)General characteristics:Compared with CPA group,PBMAH group had older age at diagnosis and a higher proportion of male patients.(2)Clinical characteristics:Compared with CPA group,PBMAH group had a longer disease duration,a higher proportion of subclinical Cushing's syndrome(CS),and a higher proportion of hypertension,impaired glucose tolerance/diabetes,bone mass reduction or osteoporosis,with higher serum potassium levels,and the differences were statistically significant(P<0.01).(3)Hormone levels:Both PBMAH and CPA groups showed ACTH-F rhythm disorder,significantly increased cortisol levels and suppressed ACTH.Compared with PBMAH group,CPA group had stronger autonomous cortisol secretion ability,manifested by increased midnight serum cortisol(F0:00),16:00 serum cortisol(F16:00),24-hour urinary free cortisol(24 h UFC)levels and lower 8:00 serum ACTH(ACTH8:00)and 16:00 serum ACTH(ACTH16:00)(P<0.01).After low-dose dexamethasone suppression test(LDDST),CPA group showed lower suppression rates of ACTH and cortisol,and higher proportions of paradoxical elevation in serum cortisol and 24 h UFC compared with PBMAH(P<0.01).Conclusions PBMAH has a longer disease course and higher proportions of comorbid metabolic disorders than CPA,mostly manifested as subclinical Cushing's syndrome.CPA has stronger autonomous cortisol secretion ability,with cortisol less likely to be suppressed after LDDST and more obvious paradoxical elevation of cortisol and 24 h UFC.

Objective To characterize multimodal metabolic disorders in subclinical Cushing's syndrome(SCS)patients with different cortisol levels,providing a reference for clinical diagnosis and treatment.Methods A retrospective analysis was conducted on the clinical data of 165 SCS patients diagnosed at the First Medical Center of Chinese PLA General Hospital due to adrenal masses from January 2014 to October 2024.Using the serum cortisol levels after the midnight 1 mg dexamethasone suppression test(1 mg DST)as the cut-off point,SCS patients were divided into high-level group(1 mg DST-F>138 nmol/L,n=96)and low-level group(50 nmol/L<1 mg DST-F≤138 nmol/L,n=69).The differences in age,gender,body mass index(BMI),blood pressure,glucolipid metabolism indices,electrolytes,hormone levels,and imaging features of adrenal adenoma(such as CT values)were compared between the two groups.Multivariate linear regression was used to analyze the correlation between CT values and metabolic indices.Results Compared with low-level group,patients in high-level group were younger(54.0±11.3 vs.57.7±10.3,P=0.034),while there were no statistically significant differences in gender ratio or BMI between the two groups(P>0.05).Both groups exhibited decreased adrenocorticotropic hormone(ACTH)levels and disrupted circadian rhythm.Compared with low-level group,high-level group showed significantly higher F0:00 levels[250.00(170.07,422.53)nmol/L vs.110.00(82.74,133.90)nmol/L]and 24-hour urinary free cortisol(24 h UFC)[568.40(377.80,875.45)nmol/24 h vs.369.40(265.40,494.69)nmol/24 h](P<0.001),with no significant differences in serum F8:00,or 1 mg DST ACTH0:00 levels(P>0.05).Except for the fasting C-peptide level in the high-level group being higher than that in low-level group[(2.88±1.01)ng/ml vs.(2.46±0.78)ng/ml,P=0.024],there were no significant differences in blood pressure,blood lipids,glycated hemoglobin(HbA1c),fasting blood glucose,fasting insulin,serum electrolytes,uric acid,and other indices between the two groups(P>0.05).The CT value of adrenal adenoma during contrast-enhanced scanning was higher in high-level group[80.00(17.80,93.00)Hu vs.52.00(35.50,75.00)Hu,P=0.006]compared with low-level group.Multivariate linear regression analysis revealed that diastolic blood pressure was positively correlated with CT values of adrenal adenomas in both plain scanning(β=0.49,95%CI 0.09-0.90)and contrast-enhanced scanning(β=2.08,95%CI 0.76-3.39),while triglyceride levels were negatively correlated with plain scanning CT values(β=-5.77,95%CI-10.88--0.66).Conclusion Patients with SCS at different cortisol levels differ in age,fasting C-peptide levels,and CT values.CT values may serve as potential imaging markers to assess metabolic risk in SCS patients.

Objective To investigate the clinical characteristics of patients with clinical and subclinical Cushing's syndrome caused by primary bilateral macronodular adrenal hyperplasia(PBMAH).Methods A retrospective analysis was performed on the clinical data of 198 patients with Cushing's syndrome caused by PBMAH diagnosed in the First Medical Center of Chinese PLA General Hospital from January 2004 to October 2024.According to clinical manifestations,the patients were classified into clinical type Cushing's syndrome(n=61)and subclinical type Cushing's syndrome(n=137),and the clinical characteristics of the two types were compared.Results The mean age at diagnosis of patients with PBMAH-induced Cushing's syndrome was(53.5±10.4)years,including 118 males and 80 females,with a male-to-female ratio of 1.475:1.Compared with the subclinical type,the clinical type had a higher proportion of females,higher levels of serum cortisol,24-hour urine free cortisol(24 h UFC),and inhibited serum cortisol after low-dose dexamethasone suppression.Additionally,the clinical type had lower plasma ACTH,larger adrenal nodules and a higher risk of surgery(P<0.05)compared with those in subclinical type.The incidences of hypertension,dyslipidemia,obesity,diabetes mellitus,hypokalemia,vitamin D deficiency,osteoporosis,coronary heart disease,and cerebrovascular disease in patients with Cushing's syndrome caused by PBMAH were 87.9%,50.5%,37.1%,36.9%,27.8%,25.9%,18.7%,18.7%and 12.1%,respectively.Among them,compared with subclinical type patients,clinical type patients had higher incidence of hypokalaemia,vitamin D deficiency and osteoporosis(P<0.05),while there were no statistically significant differences in the incidences of other comorbidities between the two types(P>0.05).The results of postoperative follow-up for PBMAH patients showed that the short-term biochemical remission rate of unilateral total adrenalectomy was 41.5%(22/53)and the long-term biochemical remission rate was 32.0%(8/25).The short-term biochemical remission rate of unilateral partial(or nodular)adrenalectomy was 52.9%(9/17),and the long-term biochemical remission rate was 14.3%(1/7).All patients who underwent unilateral total adrenalectomy plus contralateral partial resection developed adrenal insufficiency(3/3),and 1 patient(1/3)relapsed 3.4 years after surgery.Conclusion Clinical and subclinical types of Cushing's syndrome caused by PBMAH have their distinct clinical characteristics.Surgery is an effective treatment for PBMAH,but a certain proportion of patients fail to achieve biochemical remission after non-bilateral total adrenalectomy.

Objective To investigate the impact of the precision health management model on liver fibrosis,adipocytokines,and metabolic indicators in patients with non-alcoholic fatty liver dis-ease(NAFLD).Methods A total of 600 NAFLD patients were selected as study subjects and divid-ed into conventional group and precision group according to different intervention methods,with 300 patients in each group.The conventional group received routine health management,while the preci-sion group received intervention through the precision health management model.Comparisons were made between the two groups in terms of obesity indicators[waist-to-hip ratio(WHR),body mass in-dex(BMI),body fat rate(BFR),degree of obesity],fatty liver grading,liver stiffness measure-ment(LSM),and liver fibrosis indicators[laminin(LN),type Ⅳ collagen(C Ⅳ),hyaluronic acid(HA),type Ⅲ procollagen(PC Ⅲ)],hepatic adipocytokines[nuclear factor-κB(NF-κB),adi-ponectin(APN),irisin,tumor necrosis factor-α(TNF-α)],and lipid metabolism indicators[tri-glycerides(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC)]levels.Results After the intervention,the levels of WHR,BFR,BMI,degree of obesity,LSM,as well as LN,C Ⅳ,HA,PC Ⅲ,NF-κB,TNF-α,TG,LDL-C,and TC in both groups were lower than those before the intervention,and the precision group showed lower levels than the conventional group,with statistically significant differences(P＜0.05).After the intervention,the fatty liver grading in both groups was better than before intervention,and the precision group showed better fatty liver grading than the conventional group,with statistically signif-icant differences(P＜0.05).After the intervention,the levels of APN,irisin,and HDL-C in both groups were higher than those before the intervention,and the precision group showed higher levels than the conventional group,with statistically significant differences(P＜0.05).Conclusion The precision health management model can effectively improve the degree of obesity,fatty liver grading,and liver fibrosis status in NAFLD patients,reduce LSM,and regulate the levels of adipocytokines and lipid metabolism indicators,yielding significant effects.

Objective To investigate the effect of tissue-resident memory T cells(TRM)on imiquimod-induced psoriatic-like skin lesions in mice,and to elucidate the underlying mechanisms of TRM involvement in this process.Methods Forty female BALB/c mice were procured and randomly allocated into four groups:ten in the blank control group,and thirty for the establishment of a psoriasis mouse model.Following successful modeling,the thirty mice were further randomized into three groups:the model control group,the methotrexate-treated group,and the imiquimod-treated group,with ten mice in each group.Mice in the blank control group and model control group were uniformly treated with Vaseline for intervention.The methotrexate group and the imiquimod group were treated with 62.5mg of 5％imiquimod cream.The methotrexate group was administered by gavage at a dose of 1 mg/kg,and the gavage volume of each group was 10 mL/kg.The model control group,blank group and imiquimod group were gavaged with the same volume of normal saline.Treatment was conducted over six consecutive days.Subsequently,comparisons were made across groups regarding the psoriasis area and severity index(PASI),histopathological findings,inflammatory cytokine levels,and TRM cell levels.Results(1)The imiquimod group exhibited signifi-cantly lower scores for erythema(2.54±0.32),skin thickening(2.59±0.25),and scaling(2.52±0.29)compared to the methotrexate group,model control group,and blank control group(P<0.05).Additionally,the methotrexate group demonstrated reduced scores for erythema,skin thickening,and scaling compared to the model control group(P<0.05).(2)Hematoxylin-eosin(HE)staining revealed that the epidermis in the methotrexate group became thin-ner,with fewer parakeratotic cells and increased hair follicles.Conversely,the imiquimod group displayed abnor-mal cell morphology and relatively thicker white skin after modeling.(3)The imiquimod group showed significantly lower levels of TNF-α(51.63±4.39 pg/mL),IL-1β(35.53±4.15 pg/mL),IFN-γ(23.43±3.41 pg/mL),and IL-23(15.24±2.95 pg/mL)compared to the methotrexate and model control groups(P<0.05).Similarly,the methotrexate group exhibited reduced levels of TNF-α,IL-1β,IFN-γ,and IL-23 compared to the model control group(P<0.05).(4)The imiquimod group had significantly lower levels of CD8+CD103+cells(15.39±2.31)than the methotrexate and model control groups(P<0.05).Furthermore,the methotrexate group demonstrated lower levels of CD8+CD103+cells compared to the model control group(P<0.05).Conclusion Miquimod induces heavier skin lesions,faster response,and more epidermal thickening in psoriasis like mice.CD8+CD103+TRM cells and inflammatory factors may be involved in the recurrence of psoriasis.

Objective To determine the effects of cardiac resynchronization therapy at different pacing sites on electrocardiogram(ECG),left ventricular(LV)function and adverse events in elderly patients with heart failure(HF).Methods A total of 214 elderly HF patients admitted to our department between July 2021 and July 2024 were retrospectively recruited.According to different pacing sites in cardiac resynchronization therapy,they were divided into His bundle group(102 cases)and left bundle branch group(112 cases).Their grades of New York Heart Association(NYHA)cardiac function,duration of QRS complex,pacing parameters(pacing threshold,pacing perception,pacing resistance),cardiac function indicators,LV function,LV systolic synchrony[standard deviation of time to peak longitudinal strain,to peak radial strain and to peak circumferential strain(Tls-SD,Trs-SD and Tcs-SD)],and incidence of adverse events were compared between the two groups before and at 6 months after cardiac pacemaker implantation.Results In 6 months after surgery the left bundle branch group had significantly lower N-terminal pro-B-type natriuretic peptide level,smaller LV end-diastolic diameter and LV end-systolic diameter,decreased Tls-SD,Trs-SD and Tcs-SD,and shorter duration of QRS complex,but higher LV ejection fraction,cardiac index and cardiac output when compared with the His bundle group(P＜0.01).The incidence of adverse events was obviously lower in the left bundle branch group than the His bundle group(6.25％vs 15.69％,P＜0.05).Conclusion Left bundle branch pacing shows significant improvement for cardiac function in elderly HF patients,and can effectively maintain ECG stability and improve LV function.It is a safe and effective cardiac resynchronization therapy.
