AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

Objective To develop a multivariate modeling and prediction approach using the data of influenza incidence, meteorological factors and PM2.5 variables in Hefei City, and to provide new insights into multivariate modeling and prediction methods. Methods PM2.5 data were transformed into fractal dimension data and, along with meteorological data, were incorporated into a ConvLSTM model. The performance of this model was compared with traditional ARIMAX and multivariate LSTM models. Results The ARIMAX model's testing set Mean Absolute Error (MAE) was 95.75, Root Mean Square Error (RMSE) was 176.72, and Index of Agreement (IA) was 0.396642. The multivariate LSTM model's testing set MAE was 22.18, RMSE was 43.06, and IA was 0.974611. For the fractal dimension-based ConvLSTM model, the testing set MAE was 17.37, RMSE was 32.25, and IA was 0.988149. Conclusion The fractal dimension effectively captures the complexity and self-similarity of PM2.5 concentration, providing the model with richer feature information. The fractal dimension-based ConvLSTM model significantly outperforms the traditional ARIMAX model and the multivariate LSTM model in prediction accuracy and can be used for predicting the number of influenza cases.
3.Research on the autonomy issues in compulsory medical treatment
Chinese Medical Ethics 2025;38(2):207-213
Compulsory medical treatment is considered a necessary means to maintain public health. It faces many ethical dilemmas during its implementation, primarily concerning issues of autonomy. The discussion of autonomy issues is grounded in the concept, which faces difficulties in explanation and challenges in power structures. In addition to conceptual issues, autonomy also encounters various controversies in practice, including rational suicide, interpersonal relationships, bioethical principles, and other aspects. Faced with challenges, Bjorn Hofmann’s polyvalent concept clarifies the concept of autonomy, and the relational ethical approach provides innovative solutions to the practical issues of autonomy.

The deficiency of fingers due to various reasons leads to a certain degree of loss of full or part hand functions. Physical and mental health of patients are seriously affected, and patients have varying degrees of reduced quality of life. Prosthesis fingers play an important role in completing the body shape and enhancing patients’ self-confidence and self-esteem. However, how to make prosthesis fingers perform coordinated movements and restore complete functions is a crucial problem that urgently needs to be solved. This paper reviews the methods of brain-computer interface controlled fine finger movements and elaborates on the origin, current situation, and advancements of the development of this technology, laying a foundation for subsequent research, with the expectation of helping patients solve the problems arising from the insufficiency or absence of finger functions.

Objective :
To investigate the protective effect of dimethyl fumarate(DMF) on maternal intrahepatic cholestasis(ICP) during pregnancy induced by di(2-ethylhexyl) phthalate(DEHP) exposure and its mechanism.
Methods :
Thirty-two 8-week-old female institute of cancer research(ICR) mice were randomly divided into 4 groups: Ctrl group, DEHP group, DMF group and DEHP+DMF group. DEHP and DEHP+DMF groups were treated with DEHP(200 mg/kg) by gavage every morning at 9:00 a.m. DMF and DEHP+DMF groups were treated with DMF(150 mg/kg) from day 13 to day 16 of gestation by gavage. After completion of gavage on day 16 of pregnancy, maternal blood, maternal liver, placenta, and amniotic fluid were collected from pregnant mice after a six-hour abrosia. The body weight of the mother rats and the body weight of the fetus rats were sorted and analyzed; the levels of total bile acid(TBA), alkaline phosphatase(ALP), aspartate aminotransferase/alanine aminotransferase(AST/ALT) in serum and TBA in liver, amniotic fluid and placenta were detected by biochemical analyzer; HE staining was used to observe the pathological changes of liver tissue; Quantitative reverse transcription PCR(RT-qPCR) was used to detect the expression levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-6, IL-1, IL-18 and NOD-like receptor thermal protein domain associated protein 3(NLRP3) in the liver; Western blot was used to detect the expression of the nuclear factor KappaB(NF-κB) and NLRP3.
Results :
Compared with the control group, the body weight of the DEHP-treated dams and pups decreased(P<0.05); the levels of TBA, ALP, AST/ALT in the serum of dams and the levels of TBA in the liver, amniotic fluid, and placenta of dams increased(P<0.05); the histopathological results showed that liver tissue was damaged, bile ducts were deformed, and there was inflammatory cell infiltration around them; the levels of inflammation-related factors TNF-α, IL-6, IL-1, IL-18 and NLRP3 transcription in maternal liver increased(P<0.05); the expression of NF-κB and NLRP3 protein in maternal liver significantly increased( P<0. 05). Compared with the DEHP group,the body weight of both dams and fetuses significantly increased in DEHP + DMF group( P<0. 05); the levels of TBA,ALP,AST/ALT in the serum of dams and amniotic fluid of fetuses decreased( P<0. 05); the degree of liver lesions was improved; the transcription levels of inflammation-related factors TNF-α,IL-6,IL-1,IL-18 and NLRP3 in maternal liver decreased( P<0. 05); the expression of NF-κB and NLRP3 protein in maternal liver significantly decreased( P<0. 05).
Conclusion
DMF can effectively protect the DEHP exposure to lead to female ICP,and its mechanism may be through inhibiting the NF-κB/NLRP3 pathway and reducing liver inflammation.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

ObjectiveTo investigate the expression levels of miR-128-3p, SIRT1, and AMPK in the peripheral blood of patients with type 2 diabetes mellitus (T2DM) comorbid with nonalcoholic fatty liver disease (NAFLD), as well as the role of miR-128-3p in predicting NAFLD in T2DM patients. MethodsA total of 80 patients with T2DM who were hospitalized in The First Affiliated Hospital of Anhui University of Chinese Medicine from September 2022 to August 2023 were enrolled and divided into T2DM group with 40 patients and NAFLD group with 40 patients, and according to the NAFLD fibrosis score (NFS), the patients were further divided into progressive liver fibrosis group with 16 patients and non-progressive liver fibrosis group with 64 patients. General data and biochemical parameters were collected; quantitative real-time PCR was used to measure the mRNA expression levels of miR-128-3p, SIRT1, and AMPK in peripheral blood, and Western blot was used to measure the protein expression levels of SIRT1 and AMPK. The independent-samples t test was used for comparison of normally distributed data between two groups, and the Mann-Whitney U test was used for comparison of data with skewed distribution between two groups; the chi-square test was used for comparison of categorical data between two groups. The logistic regression analysis was used to identify the influencing factors for the presence of NAFLD and progressive liver fibrosis, and the receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off value of miR-128-3p for predicting NAFLD. ResultsThere were significant differences between the NAFLD group and the non-NAFLD group in body mass index, fasting plasma glucose, glycated hemoglobin, fasting insulin, fasting C-peptide, alanine aminotransferase (ALT), aspartate aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase, fibronectin, triglycerides, high-density lipoprotein cholesterol, total triiodothyronine (TT3), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), and NFS (all P<0.05). Compared with the non-NAFLD group, the NAFLD group had a significantly higher mRNA expression level of miR-128-3p in peripheral blood (t=-8.765, P<0.001) and significant reductions in the mRNA and proteins expression levels of SIRT1 and AMPK (P<0.001). There were significant differences between the progressive liver fibrosis group and the non-progressive liver fibrosis group in age, ALT, free triiodothyronine, TT3, superoxide dismutase, and miR-128-3p (all P<0.05). The logistic regression analysis showed that miR-128-3p was an independent risk factor for the development of NAFLD (odds ratio [OR]=8.221, 95% confidence interval [CI]: 2.735 — 24.714, P<0.001) and progressive liver fibrosis (OR=1.493, 95%CI: 1.117 — 1.997, P=0.007). The ROC curve analysis showed that miR-128-3p had an area under the ROC curve of 0.890 (95%CI: 0.829 — 0.950), with an optimal cut-off value of 13.165, a sensitivity of 89.3%, and a specificity of 72.7%. ConclusionThere is an increase in the expression of miR-128-3p in peripheral blood of T2DM patients with NAFLD, while there are reductions in the expression levels of SIRT1 and AMPK, suggesting that miR-128-3p has a certain diagnostic value in identifying NAFLD and liver fibrosis in such population.

ObjectiveTo investigate the improvement effect of Qibai Pingfei capsules on pulmonary vascular remodeling in rats at different stages of chronic obstructive pulmonary disease (COPD) and to analyze its possible mechanism of action. MethodsMale Sprague-Dawley (SD) rats were randomly divided into a normal group, an early COPD model group, an advanced COPD model group, an early-intervention high-dose group, a late-intervention high-dose group, an early-intervention low-dose group, a late-intervention low-dose group, an early-intervention pyrrolidine dithiocarbamate (PDTC) group, and a late-intervention PDTC group, with 15 rats in each group. A rat model of early COPD was constructed by using cigarette smoke combined with airway infusion using lipopolysaccharide(LPS), and a rat model of advanced COPD was constructed by using airway infusion with LPS, cigarette smoke, and hypoxia. All groups except the normal group were given LPS airway drops on days 1 and 14 of the experiment, smoked for 1 h per day, and administered the drug once a day for 40 weeks from day 15 onward. In the high- and low-dose groups, rats were given 1 g·kg-1 and 250 mg·kg-1 Qibai Pingfei capsules, respectively by gavage, and in PDTC groups, rats were given 100 mg·kg-1 of PDTC by intraperitoneal injection. The advanced COPD model group underwent 6 h of hypoxia per day in weeks 5-6. Lung function and mean pulmonary artery pressure were tested in rats. Morphologic changes in lung tissues were detected by hematoxylin-eosin(HE)staining. Collagen deposition in lung tissues was examined by Masson staining, and the levels of inflammatory factors including interleukin-1β(IL-1β), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α)in lung tissues were detected by enzyme-linked immunosorbent assay (ELISA). The number of inflammatory cells in the alveolar lavage fluid of rats in each group was detected by Giemsa staining, and the protein expression of Toll-like receptor 4(TLR4), myeloid differentiation factor 88(MyD88), nuclear factor-κB(NF-κB), TNF-α, vascular endothelial-cadherin(VE-cadherin), α-smooth muscle actin(α-SMA), and platelet endothelial cell adhesion molecule-1(CD31) was detected by Western blot in the lung tissues of rats. ResultsCompared with the normal group, the model group showed significantly decreased forced expiratory volume in 0.3 s (FEV0.3), forced vital capacity (FVC), and FEV0.3/FVC ratio related to lung function (P<0.05), thickening of pulmonary vasculature, increased collagen deposition in the lungs, and enhanced mean pulmonary arterial pressure and expression levels of IL-6, IL-1β, and TNF-α (P<0.05). Additionally, the model group also exhibited increased numbers of macrophages, lymphocytes, and neutrophils (P<0.05), significantly higher protein expression of TLR4, MyD88, NF-κB, TNF-α, and α-SMA (P<0.05), and significantly lower protein expression of VE-cadherin and CD31 (P<0.05). Lung function was significantly improved in the Qibai Pingfei capsules groups compared with the model group (P<0.05), with mean pulmonary arterial pressure reduced and pulmonary vascular thickening and collagen deposition in the lungs ameliorated. The Qibai Pingfei capsules groups also showed reduced expression levels of IL-6, IL-1β, and TNF-α (P<0.05) and decreased numbers of macrophages, lymphocytes, and neutrophils (P<0.05), as well as reduced protein expression of TLR4, MyD88, NF-κB, TNF-α, and α-SMA (P<0.05) and elevated protein expression of VE-cadherin and CD31 (P<0.05) in rat lung tissues. ConclusionQibai Pingfei capsules inhibits inflammatory response and endothelial-to-mesenchymal transition probably by regulating the TLR4/NF-κB signaling pathway, thus improving pulmonary vascular remodeling in COPD model rats and showing therapeutic effects in the early stage of COPD.
