AIM: To investigate the decentration of the treatment zone(TZ)and the early impact on corneal higher-order aberrations(HOAs)induced by orthokeratology(OK)lenses fitted with digital corneal topography.METHODS: A retrospective longitudinal clinical study was conducted on 28 patients(28 right eyes)who were digitally fitted with OK lenses at the Laser Vision Center of Xi'an No.1 Hospital since 2023. Longitudinal measurements were taken at baseline, 1 wk, 1 and 3 mo post-treatment to assess changes in TZ diameter, decentration magnitude and direction. Furthermore, changes in corneal HOAs were observed, and correlations of decentration with each HOAs were also analyzed.RESULTS: The mean age of patients was 10.29±2.00 years, with 15 males and 13 females, and the average baseline spherical equivalent was -2.92±0.94 D. The average TZ diameters at 1 wk, 1, and 3 mo were 3.64±0.58, 3.83±0.57, and 3.69±0.55 mm, respectively, with no statistically significant differences between 1 wk and 3 mo. Horizontal decentration values were -0.43±0.28, -0.38±0.33, and -0.31±0.37 mm after wearing lenses for 1 wk, 1 and 3 mo, respectively, while vertical decentration values were -0.33±0.20, -0.33±0.23, and -0.36±0.23 mm across the same time points. The TZ consistently decentered inferotemporally, and changes in both horizontal and vertical decentration over time were not statistically significant(Fhorizontal=1.416, Phorizontal=0.252; Fvertical=0.126, Pvertical=0.882). Significant increases in total corneal HOAs, coma, and spherical aberration were observed at 5 mm optical zone post-wear(F=45.695, 33.401, and 45.091, all P<0.001). Vertical decentration at 1 wk and 1 mo was negatively correlated with total HOAs and coma(all P<0.05), while horizontal decentration at 3 mo showed a weak negative correlation with spherical aberration(P=0.037).CONCLUSION: Digitally-fitted OK lenses achieved stable TZ diameter by 1 wk post-wear, with minor inferotemporal decentration. Early post-wear corneal total HOAs, coma and sphercal aberration increased significantly, and vertical downward decentration was associated with elevated total HOAs and coma. However, correlations between decentration and HOAs weakened by 3 mo.

Objective To analyze the correlations between the thoracic electrical impedance tomography(EIT)-derived parameters global inhomogeneity(GI),center of ventilation(COV),regional ventilation delay(RVD),and atelectasis in hospitalized patients,and to explore their effectiveness in evaluating atelectasis.Methods The clinical data of 140 hospitalized patients monitored by thoracic EIT between Sep.2024 and Jan.2025 were retrospectively analyzed.Patients were assigned to 2 groups based on chest computed tomography confirmation of atelectasis within the preceding short-term period during EIT monitoring:non-atelectasis group or atelectasis group.The algorithm software designed with MATLAB was used to acquire GI and COV.RVD was obtained through analysis with the Dr?ger EIT Data Analysis Tool 6.3 software,and patients'general data were concurrently documented.Comparative analysis of EIT-derived parameters between groups was conducted.Multivariate logistic regression analysis was employed to investigate the correlations of GI,COV,and RVD with atelectasis,while receiver operating characteristic curve analysis was performed to assess the efficacy of EIT-derived parameters in evaluating atelectasis.Results A total of 140 patients were enrolled,with 19(13.6%)cases presenting atelectasis.Compared to the non-atelectasis group,the atelectasis group demonstrated significantly higher proportions of male patients and cardiovascular disease and thoracic surgery(non-pulmonary)histories,lower body mass index(BMI),and alongside elevated GI and RVD values with reduced COV(all P＜0.05).Multivariate logistic regression analysis revealed that GI,COV,and RVD maintained independent associations with atelectasis after adjusting for age,gender,BMI,pleural effusion,and emphysema(odds ratio[OR]=1.39,95%confidence interval[CI]1.20-1.67;OR=0.85,95%CI 0.75-0.96;OR=1.22,95%CI 1.09-1.39;all P＜0.05).The area under curve(AUC)values of GI,COV,and RVD for evaluating atelectasis in hospitalized patients were 0.82,0.80,and 0.82,respectively(while RVD demonstrated a higher AUC,its clinical applicability was influenced by respiratory patterns).Conclusion Thoracic EIT-derived parameters GI and COV demonstrate significant correlations with atelectasis and may serve as valuable indicators for evaluating atelectasis in hospitalized patients.

OBJECTIVE To systematically evaluate the efficacy and safety of midazolam and dexmedetomidine/propofol for the sedation of critically ill patients undergoing mechanical ventilation， and to provide evidence-based reference for clinical treatment. METHODS Retrieved from PubMed， Embase， Web of Science， Cochrane Library， Clinical trials. gov， China Journal Full Text Database， Chinese Science and Technology Journal Database， Wanfang database and China Biomedical Literature Database， the data on the efficacy and safety of midazolam and dexmetomidine/propofol for the sedation of critically ill patients undergoing mechanical ventilation were collected from the establishment of the database to March 31， 2023. After extracting data from clinical studies that met the inclusion criteria， the meta-analysis was conducted by using the RevMan 5.3 statistical software. RESULTS A total of 31 literature were included， with a total of 2 765 patients. Results of meta-analysis showed that the mechanical ventilation time [MD＝14.13， 95%CI （13.75， 14.52）， P＜0.000 01] and the length of hospitalization in the intensive care unit [MD＝0.92， 95%CI （0.54， 1.30）， P＜0.000 01] of patients in the midazolam group was longer than dexmedetomidine/ propofol group. The incidence of bradycardia in midazolam group was lower dexmedetomidine/propofol group [OR＝0.60， 95%CI （0.41， 0.90）， P＝0.01]， but there was no statistically significant difference in the incidence of hypotension between the two groups [OR＝0.69， 95%CI （0.47， 1.01）， P＝0.06]. The incidence of delirium [OR＝3.88， 95%CI （2.74， 5.49）， P＜0.000 01]， ventilator- associated pneumonia [OR＝2.32， 95%CI （1.19， 4.51）， P＝0.01]， and respiratory depression [OR＝5.70， 95%CI （3.09， 10.52）， P＜0.000 01] in midazolam group were higher than dexmedetomidine/propofol group. CONCLUSIONS Compared with dexmedetomidine/propofol， midazolam increases patients’ mechanical ventilation time and the length of hospitalization in the intensive care unit in terms of efficacy， and increases the risk of delirium and pulmonary complications in terms of safety， but has a smaller cardiovascular impact.

Objective To prepare a nano drug(PFOB@Lip-MMC)with liposome as the carrier,liquid perfluorooc-tyl bromide(PFOB)as core and mitomycin C(MMC)loading on the liposome shell and study its inhibitory effect on the proliferation of human pterygium fibroblasts(HPFs).Methods The thin film dispersion-hydration ultrasonic method was used to prepare PFOB@Lip-MMC and detect its physical and chemical properties.Cell Counting Kit-8,Cam-PI cell viability staining and flow cytometry were employed to detect the impact of different concentrations of PFOB@Lip-MMC on the via-bility of HPFs.DiI fluorescence labeled PFOB@Lip-MMC was used to observe the permeability of the nano drug to HPFs under a laser confocal microscope.After establishing HPF inflammatory cell models,they were divided into the control group(with sterile phosphate-buffered saline solution added),PFOB@Lip group(with PFOB@Lip added),MMC group(with MMC added),PFOB@Lip-MMC group(with PFOB@Lip-MMC added)and normal group(with fresh culture medi-um added)according to the experimental requirements.After co-incubation for 24 h,flow cytometer was used to detect the apoptosis rate of inflammatory cells,and the gene expression levels of interleukin(IL)-1β,prostaglandin E2(PGE2),tumor necrosis factor(TNF)-α and vascular endothelial growth factor(VEGF)in cells were analyzed by PCR.Results The average particle size and Zeta potential of PFOB@Lip-MMC were(103.45±2.17)nm and(27.34±1.03)mV,respec-tively,and its entrapped efficiency and drug loading rate were(72.85±3.28)％and(34.27±2.04)％,respectively.The sustained-release MMC of drug-loaded nanospheres reached(78.34±2.92)％in vitro in a 24-hour ocular surface environ-ment.The biological safety of PFOB@Lip-MMC significantly improved compared to MMC.In terms of the DiI fluorescence labeled PFOB@Lip-MMC,after co-incubation with inflammatory HPFs for 2 h,DiI fluorescence labeling was diffusely dis-tributed in the cytoplasm of inflammatory HPFs.The apoptosis rate of inflammatory HPFs in the PFOB@Lip-MMC group[(77.23±4.93)％]was significantly higher than that in the MMC group[(51.62±3.28)％].The PCR examination results showed that the gene transcription levels of IL-1 β,PGE2,TNF-α and VEGF in other groups were significantly reduced com-pared to the control group and PFOB@Lip group,with the most significant decrease in the PFOB@Lip-MMC group(all P＜0.05).Conclusion In this study,a novel nano drug(PFOB@LIP-MMC)that inhibited the proliferation of HPFs was successfully synthesized,and its cytotoxicity was significantly reduced compared to the original drugs.It has good bio-compatibility and anti-inflammatory effects,providing a new treatment approach for reducing the recurrence rate after pte-rygium surgery.

Objective: To investigate the second-hand smoke behavior at home among smokers, so as to provide the reference for developing home tobacco control strategies. Methods: Permanent residents who were smokers and at the ages of 15 years and above were sampled from 10 streets (townships) in Xuhui District, Shanghai Municipality using the multi-stage random sampling and population-size proportional sampling methods in 2022. Demographic information, smoking status, awareness of second-hand smoke hazards and second-hand smoke behavior at home were collected by questionnaire surveys. Factors affecting second-hand smoke behavior at home were identified using a multivariable logistic regression model. Results: A total of 1 024 smokers were surveyed, including 769 males (75.10%) and 255 females (24.90%). The awareness of hazards of second-hand smoke was 33.59%; the awareness rate of second-hand smoke causing lung cancer in adults was the highest at 76.76%, while the awareness rate of second-hand smoke leading to premature birth and low birth weight in newborns was the lowest at 39.45%. There were 459 smokers with second-hand smoke behavior at home, accounting for 44.82%. Multivariable logistic regression analysis showed that occupation (the retired, OR=2.320, 95%CI: 1.276-4.218), frequency of smoking (often, OR=5.722, 95%CI: 3.977-8.231), smoking duration (a year and above, OR=10.089, 95%CI: 5.508-18.480), electronic cigarette use (occasionally, OR=2.994, 95%CI: 1.283-6.986), living with pregnant women or infants (no, OR=2.171, 95%CI: 1.367-3.448), family indoor smoking restrictions (no restriction, OR=13.926, 95%CI: 7.538-25.727) and awareness of second-hand smoke hazards (unknown, OR=1.562, 95%CI: 1.067-2.287) were the influencing factors for second-hand smoke behavior at home. Conclusion There were 44.82% smokers in Xuhui District with second-hand smoke behavior at home, which was influenced by occupation, living situation, smoking status, family indoor smoking restriction and awareness of second-hand smoke hazards.

Objective:To explore the incidence of sudden deafness accompanied with tinnitus, the selection of examination protocols and treatment, and to provide reference for the establishment of new guidelines for sudden deafness.Methods:CiteSpace software was used for analysis and data mining to analyze and summarize the computer-retrieved articles on diagnostic examination and treatment of sudden deafness accompanied with tinnitus collected from CNIC, Wanfang and Web of Science databases from 2011 to 2021.Results:A total of 207 randomized controlled studies were retrieved in this study, including 121 in Chinese and 86 in English. Finally, 74 Chinese literatures and 16 English literatures were included. Among the 74 valid Chinese literatures, 64 (86.5%) were accompanied with tinnitus, 58 (78.4%) with dizziness/vertigo, 25 (33.8%) with aural fullness, 10 (13.5%) with headache, 4 (5.4%) with insomnia, 4 (5.4%) with a mixture of dizziness and tinnitus, and 2 (2.7%) with vomiting. Among the 16 English literatures, 15 (93.8%) were accompanied with tinnitus, 12 (75.0%) with vertigo, 1 (6.3%) with aural fullness, and 1 (6.3%) with a mixture of various symptoms. Among the 64 Chinese articles mentioning tinnitus, only 9 mentioned tinnitus matching tests, and 1 mentioned that the treatment for tinnitus accompanying symptoms was sound therapy and psychological counseling. The incidence rates of tinnitus accompanying four different types of sudden deafness, from low to high, are as follows: low-to-mid frequency, 82.4%; mid-to-high frequency, 90.7%; complete deafness, 92.4%; and flat type, 92.8%.Conclusion:Tinnitus is the most common accompanying symptom of sudden deafness, and tinnitus matching test is an effective evaluation method. When establishing a scientific, comprehensive, and systematic diagnosis and treatment system or guidelines for sudden deafness, attention should be paid to the diagnosis and treatment of tinnitus symptoms and their adverse psychological reactions, in order to reduce the incidence of tinnitus patients in the later stage of recovery from sudden deafness.

Objective To identify the biomarkers for early rheumatoid arthritis(RA)diagnosis and explore the possible immune regulatory mechanisms.Methods The differentially expressed genesin RA were screened and functionally annotated using the limma,RRA,batch correction,and clusterProfiler.The protein-protein interaction network was retrieved from the STRING database,and Cytoscape 3.8.0 and GeneMANIA were used to select the key genes and predicting their interaction mechanisms.ROC curves was used to validate the accuracy of diagnostic models based on the key genes.The disease-specific immune cells were selected via machine learning,and their correlation with the key genes were analyzed using Corrplot package.Biological functions of the key genes were explored using GSEA method.The expression of STAT1 was investigated in the synovial tissue of rats with collagen-induced arthritis(CIA).Results We identified 9 core key genes in RA(CD3G,CD8A,SYK,LCK,IL2RG,STAT1,CCR5,ITGB2,and ITGAL),which regulate synovial inflammation primarily through cytokines-related pathways.ROC curve analysis showed a high predictive accuracy of the 9 core genes,among which STAT1 had the highest AUC(0.909).Correlation analysis revealed strong correlations of CD3G,ITGAL,LCK,CD8A,and STAT1 with disease-specific immune cells,and STAT1 showed the strongest correlation with M1-type macrophages(R=0.68,P=2.9e-08).The synovial tissues of the ankle joints of CIA rats showed high expressions of STAT1 and p-STAT1 with significant differential expression of STAT1 between the nucleus and the cytoplasm of the synovial fibroblasts.The protein expressions of p-STAT1 and STAT1 in the cell nuclei were significantly reduced after treatment.Conclusion CD3G,CD8A,SYK,LCK,IL2RG,STAT1,CCR5,ITGB2,and ITGAL may serve as biomarkers for early diagnosis of RA.Gene-immune cell pathways such as CD3G/CD8A/LCK-γδ T cells,ITGAL-Tfh cells,and STAT1-M1-type macrophages may be closely related with the development of RA.

Objective To analyze the retrieval rate of inferior vena cava filter(IVCF)and its safety,and to make a histological analysis of the filter attachment substances.Methods The clinical data of 234 patients with IVCF,who were admitted to Affiliated Tenth People's Hospital,Tongji University,to retrieve IVCF between June 2020 and May 2023,were retrospectively analyzed.The retrieval success rate,complications and filter attachment substances were statistically analyzed,and the nature of the attachment substances was examined by using histological staining.Results The retrieval success rate in the 234 patients was 91.03％(213/234).In 17 patients the retrieval of IVCF was abandoned due to the filter capturing the thrombus,and in 4 patients the retrieval of IVCF failed due to tilting of the filter.No complications such as vena cava perforation,symptomatic pulmonary embolism and hemorrhage occurred in all patients during perioperative period.Of the 213 patients whose filter was successfully removed,the filter attachment substances was found in 156 patients.Histological staining of the filter attachment substances demonstrated that the main component of these substances was a mixed thrombus with a small amount of cellulose degeneration.Further analysis revealed that the incidence of filter attachment substances in ≤14-day group was lower than than that in＞14-day group,and the difference between the two groups was statistically significant(x2=6.791,P=0.009);and the incidence of filter attachment substances in the non-anticoagulant group was lower than that in the anticoagulant group,and the difference between the two groups was statistically significant(x2=7.774,P=0.005).Conclusion The retrieval rate of retrievable IVCFs is quite high and the retrieval procedure carries less complications,therefore,it is safe to use retrievable IVCFs in clinical practice.However,the formation of tiny thrombosis within the filter after the placement of filter cannot be ignored,which should be seriously considered in the clinical work.

Objective:To investigate the efficacy and prognosis of CLAG±DAC (Clofarabine, Cytarabine, G-CSF±Decitabine) chemotherapy in patients with relapsed/refractory acute myeloid leukemia (R/R AML) .Methods:Continuous cases of R/R AML treated with the CLAG+DAC protocol or CLAG alone at the First Affiliated Hospital of Soochow University from January 2017 to December 2021 were retrospectively analyzed. The baseline characteristics, individual treatment regimen, treatment effect, disease progression, and survival status of patients were recorded. The factors influencing the efficacy of the CLAG±DAC chemotherapy regimens were analyzed, and the overall survival (OS) time after reinduction was calculated using the Kaplan-Meier method.Results:This study included a total of 53 patients, with 33 male patients and an average age of 40.6 years. Thirty-three patients achieved complete remission (CR+CRi) of the disease after the CLAG±DAC chemotherapy regimen and six patients achieved partial remission (PR), while 14 did not. Thirty-two patients eventually underwent hematopoietic stem cell transplantation, and the median OS of the patients was 55.9 months until follow-up. Patients with disease remission after the application of the CLAG±DAC chemotherapy had a significantly longer survival time than those without remission ( P<0.001). The results of the multifactorial analysis have revealed that combined DAC ( OR=4.60, 95% CI 1.14-23.5, P=0.04) and DNMT3A mutation ( OR=0.14, 95% CI 0.01-0.89, P=0.05) were the factors influencing the efficacy of the CLAG±DAC chemotherapy regimen. The remission rate was relatively higher in patients with R/R AML combined with FLT3-ITD mutation by applying the DAC+CLAG regimen ( OR=10.84, 95% CI 1.48-288.50, P=0.04) . Conclusion:The CLAG±DAC regimen is considered effective in patients with R/R AML, whereas decitabine combined with the CLAG regimen is more suitable for patients with R/R AML combined with FLT3-ITD mutation.
