AIM: To investigate the application value of pre-treatment tear inflammatory factor levels in predicting therapeutic efficacy for dry eye patients.METHODS:Prospective controlled observational study. A total of 120 patients with dry eye(240 eyes)admitted to our hospital from November 2022 to March 2024 were included. Before dry eye treatment, the levels of inflammatory factors, including interlukin-4(IL-4), IL-6, IL-8, IL-10, IL-12, IL-13, IL-15, IL-18, IL-1β, interferon-γ(IFN-γ), tumor necrosis factor-α(TNF-α), granulocyte-colony stimulating factor(G-CSF), granulocyte-macrophage colony-stimulating factor(GM-CSF), monocyte chemoattractant protein-1(MCP-1)in the tear fluid were detected by ELISA. According to the treatment protocol in the Chinese Expert Consensus on the Treatment of Dry Eye(2020), the patients were given treatments, and the related factors affecting the treatment outcomes of dry eye patients were analyzed.RESULTS:After continuous treatment for 4 wk, all the patients completed follow-up, and they were divided into the markedly effective group(60 patients, 120 eyes)and the ineffective group(60 patients, 120 eyes)based on their therapeutic effects. The markedly effective group had significantly lower pre-treatment levels of IL-6, IL-10, IL-18, IL-1β, and TNF-α than the poor efficacy group(all P<0.05). IL-6(OR=0.994), IL-18(OR=0.998), IL-1β(OR=0.933), and TNF-α(OR=0.998)were independently associated with treatment efficacy(all P<0.05). The nomogram model yielded a C-index of 0.971(95% CI: 0.950-0.993), with calibration curves closely aligned to the ideal curve. The model demonstrated significant predictive value for early therapeutic efficacy(sensitivity=96.67%, specificity=71.67%, cutoff=208, AUC=0.866, 95% CI=0.794-0.952, P<0.001).CONCLUSION:The nomogram model constructed based on the levels of inflammatory factors in dry eye patients before treatment can well predict the treatment effect of patients.

ObjectiveTo investigate the potential mechanisms and pathways through which Gandouling (GDL) exerts its effects in the treatment of liver fibrosis in Wilson disease. MethodsSixty male SD rats were randomly divided into six groups: the normal group, the model group, the GDL low-, medium-, and high-dose groups (0.24, 0.48, 0.96 g·kg-1), and the penicillamine group (90 mg·kg-1), with 10 rats in each group. A copper-loaded Wilson disease rat model was established by gavage administration of 300 mg·kg-1 copper sulfate pentahydrate to all groups except the normal group. Hematoxylin-eosin (HE) staining and Masson staining were used to observe the pathomorphological changes in the liver. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of hyaluronic acid (HA), laminin (LN), procollagen type-Ⅲ peptide (PC-Ⅲ), and collagen type-Ⅳ (C-Ⅳ). Transmission electron microscopy was used to examine the ultrastructure of liver tissues. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect the expression levels of liver tissues and serum exosomal long noncoding RNA H19 (LncRNA H19), phosphatidylinositol 3-kinase (PI3K), protein kinase B (Akt), and mammalian target of rapamycin (mTOR). Western blot analysis was performed to assess the expression levels of PI3K, Akt, mTOR, and their phosphorylated forms, as well as autophagy-related proteins Beclin1 and microtubule-associated protein 1 light chain 3B (LC3-Ⅱ/LC3-Ⅰ) in liver tissues. Beclin1 and LC3-Ⅱ fluorescence signal intensity was observed by immunofluorescence. ResultsCompared with the normal group, the model group exhibited inflammatory cell infiltration in hepatocytes, unclear nuclear boundaries with cell cleavage and necrosis, and collagen fiber deposition around confluent areas. The levels of HA, LN, PC-Ⅲ, and C-Ⅳ were significantly elevated (P<0.01). Transmission electron microscopy revealed an increased number of autophagic vesicles, with autophagic lysosomes exhibiting a single-layer membrane structure following degradation of most envelopes. Expression levels of Beclin1 and LC3-Ⅱ/LC3-Ⅰ were significantly increased (P<0.01), and fluorescence signals of Beclin1 and LC3-Ⅱ were markedly enhanced. The protein expression levels of PI3K, Akt, mTOR, p-PI3K, p-Akt, and p-mTOR were reduced (P<0.01), while LncRNA H19 expression was increased (P<0.01), and mRNA expression levels of PI3K, Akt, and mTOR were decreased (P<0.01). After treatment with GDL, the degree of liver fibrosis was significantly improved, with decreased levels of HA, LN, PC-Ⅲ, and C-Ⅳ. The number of autophagic vesicles was significantly reduced, and expression levels of Beclin1 and LC3-Ⅱ/LC3-Ⅰ proteins were lower (P<0.01). The fluorescence signals of Beclin1 and LC3-Ⅱ weakened dose-dependently. The protein levels of PI3K, Akt, mTOR, p-PI3K, p-Akt, and p-mTOR were elevated (P<0.01), while the expression level of LncRNA H19 was reduced (P<0.01). Furthermore, the mRNA expression levels of PI3K, Akt, and mTOR increased (P<0.05, P<0.01). ConclusionGDL may alleviate liver fibrosis and reduce liver injury by regulating the PI3K/Akt/mTOR autophagy signaling pathway via LncRNA H19.

Objective To investigate the factors affecting the occurrence of new postoperative cardiac complications in patients undergoing esophageal cancer surgery with concomitant coronary heart disease. Methods Clinical data of patients who underwent esophageal cancer surgery with coronary heart disease at the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from December 2019 to June 2023 were collected. Patients were divided into two groups based on whether they experienced postoperative cardiac complications. Using the occurrence of cardiac complications as the dependent variable, a multivariate logistic regression model was established to identify related influencing factors. Results A total of 223 patients were included, comprising 148 males and 75 females, with an average age of (71.78±6.31) years (range 53-88 years). Seventy-one (31.84%) patients experienced at least one new cardiac complication postoperatively, including 2 acute coronary syndrome, 13 heart failure, and 59 new-onset postoperative arrhythmias. Univariate analysis showed that age, systemic immune-inflammation index, pulmonary infection, need for invasive mechanical ventilation due to respiratory failure, acute respiratory distress syndrome (ARDS), acute delirium, pleural effusion requiring drainage, and acute renal failure were risk factors for postoperative new-onset cardiac complications (all P<0.05). Multivariate logistic regression analysis identified age, postoperative length of hospital stay, ARDS, and systemic immune-inflammation index as independent risk factors for new cardiac complications in esophageal cancer patients with coronary heart disease. Conclusion Strengthening perioperative management of esophageal cancer patients, ranging from preoperative evaluation to postoperative complication treatment, is crucial. Particular attention should be paid to age, ARDS, and other indicators to improve postoperative prognoses in patients with coronary heart disease complicated by esophageal cancer.

Objective:
To evaluate the effects of a multidisciplinary weight management intervention, so as to provide a reference for the formulation of overweight and obesity intervention measures.
Methods:
From April to September 2025, overweight and obese residents aged 18-60 years who participated in a weight loss competition at the Health Management Center of Beilun People's Hospital in Ningbo City were selected as study subjects. They were divided into a control group and an intervention group. The control group received conventional weight management, while the intervention group received the multidisciplinary integrated weight management in addition to the conventional weight management, for a total intervention period of 8 weeks. Weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and blood pressure were collected before and after the intervention through physical examinations and laboratory tests. The generalized estimating equations (GEE) method was employed to analyze the differences in indicators between the two groups before and after the intervention.
Results:
The control group comprised 241 participants, including 161 females (66.80%), with a mean age of (35.66±7.80) years. The intervention group consisted of 127 participants, including 86 females (67.72%), with a mean age of (36.80±7.05) years. No statistically significant differences were observed between the two groups at baseline in terms of age, gender, weight, BMI, or waist-to-hip ratio (all P>0.05). Results from the GEE analysis indicated significant interactions between group and time for weight, BMI, waist circumference, and hip circumference (all P<0.05) with greater reductions in these parameters observed in the intervention group compared to the control group before and after the intervention. Similarly, significant interactions between group and time were observed for FBG, TG, TC, and LDL-C (all P<0.05), with the intervention group demonstrating larger decreases in these markers compared to the control group. However, no statistically significant interactions between group and time were observed for waist-to-hip ratio, HDL-C, systolic blood pressure, and diastolic blood pressure (all P>0.05). Following the intervention, a weight loss exceeding 10% was achieved by 13 participants (5.39%) in the control group and 62 participants (48.82%) in the intervention group. The proportion of individuals with a weight loss exceeding 10% was significantly higher in the intervention group compared to the control group (P<0.05).
Conclusion
Compared to conventional weight management, multidisciplinary integrated weight management demonstrated greater efficacy in improving weight-related indicators and blood glucose, blood lipids, and enhancing weight loss outcomes among overweight and obese residents.

Objective To preliminarily design a wide-energy-spectrum CR-39 solid-state nuclear track individual neutron dosimeter with different energy sections. Methods The thickness of the converter was optimized using the Monte Carlo SRIM program to broaden the energy range of the dosimeter. The self-made wide-energy-spectrum CR-39 individual neutron dosimeter was calibrated using 241Am-Be, 252Cf, and thermal neutron sources to evaluate its dosimetric performance, including linearity, energy response, and neutron energy resolution. Results The linear correlation coefficient of the measurement system exceeded 0.98. The relative deviations of the energy response were 35.0% for blank section and 42.0% for polyethylene section, falling within the range of −50% to + 100% and meeting the monitoring requirements. The detection sensitivity for thermal neutron dose was 67 137.2 tr·cm−2·mSv−1, and the detection sensitivity for thermal neutron fluence was 0.98 × 10−3 tr·n−1, demonstrating good thermal neutron detection capability. Conclusion The self-made wide-energy-spectrum CR-39 individual neutron dosimeter fundamentally meets the requirements for individual neutron dose monitoring and is suitable for individual neutron dose monitoring in the energy range of thermal neutrons (up to approximately 15 MeV).

Abstract
Psychological stress is a significant contributing factor for the decline in male sperm quality. In terms of the psychological mechanism, the decline of sperm quality due to psychological stress is associated with increased perceived stress and different coping strategies. External sources of stress can elevate stress perception, then affect sperm quality, while coping strategies may modulate the impact of stress perception on sperm quality. In terms of the physiological mechanism, psychological stress disrupts the normal functioning of the sympathoadrenal system, hypothalamic-pituitary-adrenal axis and hypothalamic-pituitary-gonadal axis, leading to disturbances in the essential endocrine environment for sperm production. This review synthesizes the psychological and physiological mechanisms through which psychological stress influences male sperm quality, providing insights into the prevention and treatment of male infertility.

AIM: To compare the clinical effectiveness of using multifocal defocus spectacle lenses, orthokeratology lenses, and single-vision spectacle lenses in patients with myopia and small-angle intermittent exotropia.METHODS: This retrospective study included 150 patients aged 8-15 years with basic intermittent exotropia, strabismus of -10△ to -20△ prism diopters(D)(block lenses), and spherical equivalents of -1.00 to -5.50 D, who visited our hospital from June 2021 to September 2022. They were selected and divided into three groups on a voluntary basis: the HAL group(50 patients with multifocal myopia defocus spectacle lenses), the OK lens group(50 patients with nighttime orthokeratology lenses), and the SVL group(50 patients with regular single-vision spectacle lenses). After wearing the lenses consistently, changes in axial length, prism diopters with the naked eye and lenses(prism at 33 cm), positive fusional vergence of blurred points, and near stereopsis were observed and compared among groups before intervention and after 1 a. The Newcastle control score(NCS)was used to evaluate the eye position control ability of the patients in the three groups.RESULTS: Before the intervention, the axial lengths of the HAL, OK lens, and SVL groups were 24.83±0.91, 24.93±0.97, and 24.98±0.68 mm, respectively(P>0.05). After 1 a, the axial lengths of the three groups were 25.02±0.90, 25.18±0.97, and 25.45±0.65, respectively(P<0.05). Compared with an increase of 0.47±0.30 mm in the SVL group after 1 a, the axial length of the HAL and OK lens groups increased by 0.19±0.06 and 0.25±0.21 mm, respectively(both P<0.05). Before intervention, the prism diopters of the HAL, OK lens, and SVL groups measured using the prism were -15.00△±3.12△, -14.34△±3.00△ and -14.06△±3.22△, respectively. After 1 a, the prism diopters of the three groups with lenses were -9.34△±3.84△, -18.42△±4.41△, and -19.58△±5.21△, respectively, which increased by 5.66△±2.13△, -4.08△±3.34△, and -5.52△±3.70△, respectively, compared with the preintervention values(P<0.05). Before intervention, the near stereopsis in the HAL, OK lens, and SVL groups were 89.20″±54.65″, 93.00″±52.54″, and 88.40″±55.31″, respectively(P>0.05). After 1 year, near stereopsis in the groups were 76.00″±20.40″, 81.20″±18.91″, and 100.60″±51.41″, respectively(P<0.05). The positive fusional vergence(fuzzy point)of the three groups was 15.04±1.97, 15.14±1.67, and 14.62±1.47, respectively, before intervention(P>0.05), and it was 17.10±2.02, 13.12±1.41, and 13.26±2.45, respectively, after 1 a(P<0.05). In addition, the eye position control in the HAL group was significantly better than that in the OK lens and SVL groups after wearing lenses for 1 a(P<0.05).CONCLUSION: For patients with myopia and small-angle intermittent exotropia, wearing HAL can effectively control changes in strabismus and axial length compared with OK lenses and SVL, particularly for better control of strabismus, whereas wearing OK lenses or SVL would result in exotropic drifts. Stereopsis and positive fusional vergence were significantly improved in the HAL group.

Implementation strategies are targeted interventions aimed at promoting the adoption, implementation, and sustainment of research findings or evidence-based practices in routine healthcare. If implementation strategies can precisely match implementation barriers and facilitators, the likelihood of successful implementation will increase. The CFIR-ERIC matching tool, which can match corresponding ERIC implementation strategies based on CFIR barriers, is a convenient and direct tool for developing implementation strategies. This paper provides a detailed overview of the origins and development of the CFIR-ERIC matching tool, outlines its contents and usage, and illustrates how to apply the tool to develop implementation strategies by using a brief smoking cessation intervention project as an example. The paper also discusses the advantages and limitations of using this tool for developing implementation strategies, with the aim of providing methodological reference for other researchers.
