OBJECTIVE: To investigate the effect of different previous treatments on the efficacy of flumatinib in patients with chronic myeloid leukemia (CML). METHODS: The clinical data of 69 patients with CML treated with flumatinib in the Affiliated Hospital of Xuzhou Medical University from 2019 to 2024 were retrospectively analyzed. The patients were divided into a first-line flumatinib group and a first-line non-flumatinib group according to whether flumatinib was used as first-line treatment. The molecular response (MR) at 3, 6 and 12 months of treatment was compared between the two groups to evaluate the early efficacy. The first-line non-flumatinib group was further divided into imatinib group, nilotinib group, and dasatinib group according to the previous first-line drugs used. The efficacy data of these three groups at 3, 6 and 12 months after switching to flumatinib were collected, and the MR was evaluated to compare efficacy differences. RESULTS: The rate of early molecular response (EMR) in the first-line flumatinib group was significantly higher than that in the first-line non-flumatinib group (P < 0.05). At 6 months and 12 months of treatment, the proportion of patients achieving MR 4.5 in the first-line flumatinib group was significantly higher than that in the first-line non-flumatinib group (P < 0.05). Compared with the imatinib and nilotinib groups, the previous dasatinib group showed a significantly higher proportion of patients achieving MR 5.0 at 3, 6, and 12 months after switching to flumatinib (P < 0.05). CONCLUSION Compared with the previous treatment with other tyrosine kinase inhibitors (TKIs), initial use of flumatinib at diagnosis enable patients to achieve deeper molecular remission more rapidly. Compared with previous use of imatinib or nilotinib, previous use of dasatinib is associated with deeper molecular remission after switching to flumatinib.

Objective:To study the effect of anti-melanoma differentiation-related gene 5(MDA5) antibody positive dermatomyositis on the heart of patients.Methods:A total of 71 patients with dermatomyositis diagnosed in Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 1, 2014 to December 31, 2019 were enrolled as the sample group, including anti-MDA5 (+) group( n=28); anti-MDA5(-) groups( n=43). Electrocardiogram and echocardiography were performed in the sample group and the control group. The electrocardiogram, echocardiography and other relevant clinical data of the anti-MDA5 (+) group, anti-MDA5 (-) group and the healthy control group were retrospectively analyzed. The logistic regression analysis model was used to analyze the related factors influencing cardiac involvement in anti-MDA5 (+) patients. Results:In the anti-MDA5 (+) group, more than half of the patients showed elevated levels of lactate dehydrogenase (21/28, 75%) and α-hydroxybutyrate dehydrogenase (16/28, 57%), and 11%(3/28) showed elevated levels of creatine kinase isoenzyme and myoglobin. Compared with the anti-MDA5 (-) group, the white blood cell count in the blood routine of the anti-MDA5 (+) group [5.2 (4.0, 6.5) ×10 9/L vs. 7.8 (5.6, 10.6)×10 9/L, Z=-3.447, P=0.001], creatine kinase [62.5 (29.3, 108.3) U/L vs. 481.0 (179.0, 2 738.0) U/L, Z=-5.895, P<0.001], lactate dehydrogenase [313.0 (239.0, 362.0) U/L vs. 448.0 (291.0, 542.0) U/L, Z=-3.236, P<0.001], creatine kinase isoenzyme [1.9 (1.1, 3.9)ng/ml vs. 17.7 (4.0, 67.2) ng/ml, Z=-4.724, P<0.001], myoglobin [28.2 (20.0, 43.0) ng/ml vs. 307.4 (48.1, 612.2) ng/ml, Z=-4.800, P<0.001]. Electrocardiogram analysis showed that QRS axis [33.5±265.9 vs. 46.9±22.4, t=-2.900, P=0.004], SV1 amplitude [0.7 (0.4, 0.9) vs. 0.9 (0.7, 1.0), Z=-2.148, P=0.023] in anti-MDA5 antibody (+) group in anti-MDA5 antibody (+) group were lower than anti-MDA5 antibody (-) group. QRS duration [84.0 (78.0, 96.5) vs.92.0 (87.8, 100.5), Z=-2.900, P=0.004], QRS axis [33.5±265.9 vs. 46.9±20.4, Z=-2.32, P=0.023] in the anti-MDA5 antibody (+) group were lower than those in healthy control group. Echocardiographic analysis showed that the E peak of anti-MDA5 (+) group [63.0 (52.5, 69.5)] was significantly lower than that of anti-MDA5 (-) group [85.0 (68.0, 108.0), Z=-4.926, P<0.001)]and healthy control group [67.0 (62.8, 80.3), Z=-2.897, P=0.004]. The peak A of anti-MDA5 (+) group [65.5 (56.5, 80.0)] was significantly lower than that of anti-MDA5 (-) group [76.0 (65.0, 90.0), Z=-2.631, P=0.011], but higher than that of healthy control group [55.0(51.0, 66.5), Z=-4.550, P<0.001]. There was no significant difference in echocardiographic findi-ngs among the other groups. All patients with anti-MDA5 (+) dermatomyositis had interstitial lung disease (28/28, 100%). Patients with MDA5 antibody (+++) are more likely to have cardiac involvement than patients with MDA5 antibody (++). Conclusion:The results of relevant examinations in anti-MDA5-DM patients suggest that there is damage to myocardial cells and cardiac function.

Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

Objective:To analyze the association of sedentary time and physical activity with the risk of developing chronic obstructive pulmonary disease (COPD) in non-smoking women aged 40 years and above in Songjiang District, Shanghai.Methods:Based on a natural population-based cohort in Songjiang, a total of 18 707 non-smoking women who were aged 40 years and above and without COPD at baseline survey were enrolled in the study. Cox proportional risk regression model was used to analyze the associations of the duration of sedentary behavior, physical activity with the risk for COPD at baseline survey, and the hazard ratio ( HR) of risk for COPD and its 95% CI were calculated. Stratified analyses were performed based on age, BMI, history of respiratory diseases and so on. Sensitivity analyses were conducted by excluding the cases diagnosed with COPD within one year after the baseline survey. Results:As of March 31, 2024, a total of 691 new COPD cases had been recorded after a median follow-up time of 6.96 years with an incidence density of 53.22 per 10 000 person-years. After adjusting for relevant confounders, in the tertile subgroups of sedentary time, the risk for COPD reduced by 17% in the short sedentary time group compared with the long sedentary time group ( HR=0.83,95% CI:0.70-0.99). Compared with the low physical activity level and long sedentary time group, the risk for COPD reduced by 24% in the high physical activity level and short sedentary time group ( HR=0.76, 95% CI: 0.61-0.95) and by 23% in the low physical activity level and short sedentary time group ( HR=0.77, 95% CI: 0.60-0.97). Compared with the non-physical exercise and long sedentary time group, the risk for COPD reduced by 28% in the non-physical exercise and short sedentary time group ( HR=0.72, 95% CI: 0.60-0.87). These associations remained when the cases diagnosed with COPD within one year of the baseline survey were excluded. Conclusions:Increasing physical activity and reducing sedentary time have beneficial effects to prevent COPD in non-smoking women, and reducing sedentary time alone may also reduce the risk for COPD if increasing physical exercise or other physical activity is not possible.

Objective:To investigate the clinical characteristics, prognosis, and the impact of different secondary prevention strategies on stroke recurrence in patients with carotid web (CaW)-associated acute anterior circulation large vessel occlusion (LVO).Methods:A retrospective analysis was conducted on 401 patients with acute anterior circulation LVO who underwent mechanical thrombectomy at 2 advanced stroke centers, Xingtai Central Hospital and Xingtai People′s Hospital, from January 2018 to June 2024. CaW was identified using digital subtraction angiography (DSA) and other imaging modalities. Based on the presence of CaW, patients were divided into CaW group and non-CaW group. Differences between the 2 groups in baseline characteristics, clinical features, and clinical outcomes were compared, and long-term follow-up was conducted for the CaW group.Results:Among the 401 patients, the CaW group consisted of 16 patients (4.0%), while the non-CaW group included 385 patients (96.0%). Compared to the non-CaW group, patients in the CaW group were younger [53 (46, 58) years vs 65 (56, 76) years, Z=-3.811, P<0.001], had a higher proportion of M1 segment middle cerebral artery occlusion [13/16 vs 54.0% (208/385), χ2=4.602, P=0.032] and a lower proportion of internal carotid artery terminus occlusion [1/16 vs 40.0% (154/385), χ2=6.024, P=0.014]; the 90-day modified Rankin Scale (mRS) score was significantly lower in the CaW group [1.00 (0, 1.75) vs 3.00 (1.00, 4.00), Z=14.210, P<0.001], and the proportion of patients with favorable functional independence (mRS score 0-2) was significantly higher [15/16 vs 45.7% (176/385), χ2=12.350, P<0.001] in the CaW group; the incidence of pneumonia in the CaW group was significantly lower [2/16 vs 42.6% (164/385), χ2=4.562, P=0.033]. Among the 16 CaW patients, 10 received antiplatelet therapy, 4 underwent carotid artery stenting (CAS), and 2 underwent carotid endarterectomy (CEA). During a median follow-up of 29 months, patients who underwent CAS and CEA had no stroke recurrence, while 2 patients who received antiplatelet therapy had stroke recurrence and subsequently underwent CAS and CEA. Conclusions:The proportion of CaW among patients with acute anterior circulation LVO was 4.0%. The patients with CaW were younger and had a higher proportion of M1 segment middle cerebral artery occlusion. Following mechanical thrombectomy, patients in the CaW group had good functional outcomes. Simple drug therapy may be insufficient to prevent stroke recurrence in CaW patients, and CAS and CEA may be effective therapeutic options.

Objective:To observe and analyze the correlation between ectopic foveal inner layer (EIFL) and the EIFL-based idiopathic epiretinal membrane (ERM) staging system and the anatomic and functional prognosis of ERM eyes post pars plana vitrectomy (PPV).Methods:A retrospective study. From January 1, 2020 to October 30, 2023, 345 eyes of 330 patients diagnosed with idiopathic ERM in Department of Ophthalmology of Peking University People's Hospital and treated with standard transciliary flat three-channel 25G PPV combined with ERM and internal limiting membrane exfoliation were included in the study. Among them, 96 were males (111 eyes) and 234 were females (234 eyes). The mean age was (66.8±7.7) years. All study eyes received standard three-port 25G PPV combined with ERM and internal limiting membrane peeling. All study eyes underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examinations. BCVA was performed using a standard logarithmic visual acuity chart and converted to logarithm of the minimum angle of resolution visual acuity for statistical analysis. EIFL thickness and central foveal thickness (CFT) on OCT were measured. ERM eyes were grouped into stage Ⅰ, Ⅱ, Ⅲ and Ⅳ according to ERM staging scheme based on EIFL; disorganization of the retinal inner layers (DRIL) of study eyes were assessed and grouped into no, mild and severe groups. The correlation between ERM staging as well as EIFL thickness and the anatomical and functional prognosis 6 months post-PPV were analyzed.Results:Among 345 study eyes, 12, 87, 174 and 72 eyes were stage Ⅰ-Ⅳ ERM respectively, 63 with no DRIL, 216 with mild DRIL and 66 with severe DRIL. Among the 153 eyes with macular edema, the edema subsided in 66 eyes (43.1%, 66/153) 6 months after the operation. Eighty-seven eyes (56.9%, 87/153) did not regress. The edema subsided 6 months after the operation was not significantly correlated with the ERM stage before the operation ( χ2=3.331, R=?0.145, P=0.304) or the degree of DRIL ( χ2=0.655, R=?0.108, P=0.445). The results of the correlation analysis showed that logMAR BCVA 6 months after the surgery was positively correlated with the degree of DRIL before the surgery ( Tau-b=0.236), ERM stage ( Tau-b=0.194), CFT ( r=0.383), and EIFL thickness ( r=0.317) ( P<0.05). There was no significant correlation with the thickness of the outer nuclear layer before the operation ( r=0.004, P>0.05). Preoperative ERM stage ( Tau-b=0.303, P<0.001) and DRIL severity ( Tau-b= 0.238, P=0.001) were positively correlated with CFT at 6 months after surgery. Conclusion:The ERM stage and EIFL thickness before the operation are positively correlated with logMAR BCVA and CFT 6 months after the operation.
