INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

Objective:To explore the latent categories of sleep quality in shift nurses using latent profile analysis, and analyze the characteristics and influencing factors of each category.Methods:A convenience sampling method was used to select 1 480 shift nurses from three ClassⅢ Grade A hospitals in Fuyang city from January to February 2024. Data were collected using a general information questionnaire, Pittsburgh Sleep Quality Index, Perceived Stress Scale, and the Morningness-Eveningness Questionnaire-5. Latent profile analysis was performed to identify the latent categories of sleep quality, and multivariate logistic regression analysis was used to explore the influencing factors of different sleep quality categories. In this study, a total of 1 480 questionnaires were distributed. After excluding 28 invalid questionnaires, 1 452 valid questionnaires were retrieved, the effective recovery rate of the questionnaires was 98.11%.Results:The sleep quality of 1 452 shift nurses was classified into four latent categories: 44.5% (647/1 452) were in the "sleep impairment" category, 44.6% (648/1 452) in the "good sleep" category, 4.0% (58/1 452) in the "difficulty falling asleep-low efficiency" category, and 6.8% (99/1 452) in the "sleep disorder-medication-induced sleep" category. Multivariate logistic regression analysis revealed that perceived stress, monthly night shift frequency, sleep timing, daytime napping, and years of work experience were significant influencing factors for sleep quality ( P<0.05) . Conclusions:Sleep quality among shift nurses shows heterogeneity. Nursing managers should develop tailored management strategies and implement targeted sleep hygiene interventions based on nurses' sleep quality characteristics to improve their sleep quality.

Objective To investigate the expression of MPZL1 in gastric cancer tissues, its relation with the prognosis, and its effects on proliferation and colony formation of gastric cancer. Methods GEPIA and UALCAN databases were used to analyze the expression of MPZL1 in various malignant tumors. The KM Plotter database and UALCAN database were used to analyze the effect of MPZL1 on the overall survival of gastric cancer patients. The expression of MPZL1 protein and the changes of apoptosis-related proteins in gastric cancer cells were detected by Western blot, and the effects of MPZL1 expression on cell proliferation and colony formation were detected by CCK-8 and colony formation assay, respectively. Results MPZL1 was found to be highly expressed in various malignant tumors by GEPIA database. The results of UALCAN and KM Plotter databases analysis showed that MPZL1 was highly expressed in gastric cancer tissues, and might be correlated with the overall survival of gastric cancer patients. The results of CCK-8 and colony formation assay showed that the overexpression of MPZL1 promoted the proliferation and colony formation ability of gastric cancer cells (P < 0.05). Western blot results showed that compared with control group, the expression levels of pro-apoptotic proteins Bad and Caspase-7 in the overexpression group were significantly lower while those in knockdown group were higher. Conclusion MPZL is highly expressed in gastric cancer tissues and promotes the proliferation and colony formation of gastric cancer cells, which may be related to the inhibition of apoptosis.

Objective The objective of this study was to investigate the effect of depression on serum levels of C-reactive protein(CRP)and high-sensitivity C-reactive protein(hs-CRP),and prognosis in liver cancer patients. Methods A total of 251 patients with liver cancer undergoing hepatectomy were enrolled. The hospital anxiety and depression scale( HADS-D) and 9-item patients health questionnaire(PHQ9) were assessed for depression before 3 days for surgery. Patients were divided into depression group(n=95)and non-depression group(n=156) according to the scores. Preoperative serum levels of CRP,hs-CRP,ALT and AST were measured and compared between the depression and non-depression groups. Survival analysis Kaplan-Meier method was used to compare the disease-free survival(DFS)and total survival(OS)between the two groups. Results The serum levels of CRP, hs-CRP,ALT and AST in the depression group were significantly higher than those in the non-depression group(P<0. 05). The follow-up of 3. 5-year showed that 164 patients(65 in depression group and 99 in non-depression group)had recurrence or metas-tasis and 47 patients(22 in depression group and 25 in non-depression group) died. The DFS and OS in the depression group were significantly lower than those in the non-depression group(P< 0. 05). Cox multiple regression analysis showed that liver function grading,BCLC staging and depression were independent risk factors for the prognosis of liver cancer. Spearman correlation analysis showed that patients′degree of depression was positively correlated with serum levels of CRP and hs-CRP(P<0. 05),DFS and OS were negatively correlated with serum levels of CRP and hs-CRP(P<0. 05). Conclusion Depression may mediate elevated serum levels of CRP and hs-CRP,maintain inflammatory response in patients,lead to increased liver function damage,elevate levels of ALT and AST,and thus adversely affect the prognosis of patients with liver cancer.

Objective To explore the characteristics of the effect of echinacoside on lipid metabolism in type 2 diabetic mice,and to investigate the content of growth factor 21 in liver tissue of diabetic mice,providing further insight into the possible way of regulating blood lipid metabolism in type 2 diabetic mice with Echinacea.Methods Twenty db/db mice (6-week-old) were randomly divided into two groups:experimental group and model group;while six db/m mice (SPF) (6-week-old) were control group.We detected the fasting blood glucose after 2 weeks that was higher than 16.7mmol/L in experiment.Each group was given sterilized distilled water,echinaco side,sterilized distilled water.The serum total,cholesterol,triglyceride,high density lipoprotein,low density lipoprotein,alanine aminotransferase level,aspartate,aminotransferase level,and the liver tissue measurement of fibroblast growth factor 21 levels were detected after eight weeks.Results The model group serum TG,TC and LDL were significantly higher than the control group (P ＜ 0.01).The content of serum HDL was significantly lower than the control group (P ＜ 0.01).Experimental group of serum TG,TC and LDL levels were significantly lower than the model group (P ＜ 0.01).The content of serum HDL was significantly higher than that in the model group (P ＜ 0.01).The expression of FGF21 in model group in liver were significantly lower than that of control group (P ＜ 0.01).The experimental group the expression of FGF21 in mouse liver was significantly higher than that in the model group (P ＜ 0.01).The content of ALT and AST in serum of model group was significantly higher than the control group (P ＜ 0.01).Experimental group serum ALT,AST were significantly lower than the experimental group (P ＜ 0.01).Conclusion After 8 weeks of administration,the serum lipid metabolism disorder of db/db diabetic mice was significantly improved,and the liver function damage was not increased.The mechanism of FGF21 may be related to the improvement of the expression level of liver tissue.
