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.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes. If not intervened in time, NAFLD may develop into liver fibrosis or liver cancer, and ultimately threatening life. NAFLD has complicated etiology and pathogenesis, and there are no effective therapeutic means and specific drugs. Currently, insulin sensitizers, lipid-lowering agents and hepatoprotective agents are often used for clinical intervention, but these drugs have obvious side effects, and their effectiveness and safety need to be further confirmed. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays a central role in maintaining energy homeostasis. Activated AMPK can enhance lipid degradation, alleviate insulin resistance (IR), suppress oxidative stress and inflammatory response, and regulate autophagy, thereby alleviating NAFLD. Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects. In this article, we reviewed the biologically active natural herbal medicines (such as natural herbal medicine formulas, extracts, polysaccharides, and monomers) that reported in recent years to treat NAFLD via regulating AMPK, which can serve as a foundation for subsequent development of candidate drugs for NAFLD.

Objective To investigate the distribution of traditional Chinese medicine(TCM)syndromes in patients with type 2 diabetic retinopathy(T2DR)and to explore the correlation of TCM syndromes with serum inflammatory factors and adiponectin(APN)levels,so as to provide evidence for TCM syndrome differentiation of T2DR.Methods A cross-sectional case-control study was conducted in 42 patients(involving 84 eyes)diagnosed as T2DR in the Department of Ophthalmology,Ganzhou People's Hospital from September 2022 to March 2023.The correlation between fundus fluorescein angiography(FFA)staging and TCM syndrome differentiation in patients with T2DR was explored.The relationship between TCM syndrome types and serum levels of inflammatory factors and APN,as well as the differences in serum inflammatory factors and APN levels of the patients with various FFA stages were analyzed.The correlation between each variable and TCM syndrome types in patients with T2DR was investigated.Results(1)Among the 42 patients with T2DR,27 cases were male and 15 cases were female,and their age averaged(54.0±12.0)years old.Among them,14 cases(33.3％)were differentiated as liver-kidney deficiency with malnutrition of eye collateral syndrome,15 cases(35.7％)were differentiated as yin-essence deficiency with internal dry-heat syndrome,9 cases(21.4％)were differentiated as qi-yin deficiency with collateral stasis and obstruction syndrome,4 cases(9.5％)were differentiated as yin-yang deficiency with blood stasis and phlegm coagulation syndrome,and none case(0.0％)was differentiated as spleen dysfunction and water-damp obstruction syndrome.(2)FFA staging showed that FFA staging ≥ 4[i.e.,having proliferative diabetic retinopathy(PDR)]was found in 78.6％(11/14)of the patients with liver-kidney deficiency with malnutrition of eye collaterals syndrome,73.3％(11/15)of the patients with yin-essence deficiency with internal dry-heat syndrome,100％(9/9)of the patients with qi-yin deficiency with collateral stasis and obstruction syndrome,and 100％(4/4)of the patients with yin-yang deficiency with blood stasis and phlegm coagulation syndrome.But the intergroup comparison showed no significant differences among various syndrome types(P=0.272).(3)Among the 42 patients with T2DR,35 patients(83.3％)had higher level of tumor necrosis factor-α(TNF-α),28 patients(68.3％)had higher level of C-reactive protein(CRP)and 38 patients(90.5％)had higher level of glycosylated hemoglobin(HbA1c)than the normal.However,there was no significant difference in the levels of serum inflammatory factors of TNF-α,CRP,interleukin-6(IL-6)and vascular endothelial growth factor(VEGF),APN and HbA1c among the patients with different FFA stages(P＞0.05),neither did the difference in serum APN,TNF-α,CRP,IL-6 and VEGF levels among the patients with different TCM syndrome types(P＞0.05).(4)The correlation analysis showed that the patients with yin-yang deficiency with blood stasis and phlegm coagulation syndrome had a shorter course of eye diseases than the patients with liver-kidney deficiency with malnutrition of eye collaterals syndrome(r=-0.467,P=0.051),had higher CRP level than the patients with yin-essence deficiency with internal dry-heat syndrome(r=0.592,P=0.010),and had higher CRP level(r=0.668,P=0.013)and a longer course of diabetes(r=0.629,P=0.021)than the patients with qi-yin deficiency with collateral stasis and obstruction syndrome.Conclusion Increased serum TNF-α and CRP expressions are presented in the patients with T2DR.Liver-kidney deficiency with malnutrition of eye collaterals syndrome and yin-essence deficiency with internal dry-heat syndrome are the common syndromes in T2DR.Yin-yang deficiency with blood stasis and phlegm coagulation syndrome is closely correlated with CRP level,and the patients with yin-yang deficiency with blood stasis and phlegm coagulation syndrome have a longer course of diabetes.

This article reports a case of primary Müllerian adenosarcoma(MA)of the ovary admitted to the Obstetrics and Gynecology Hospital,Fudan University in 2022,reviews the literature on this rare disease,and shares the experience of its diagnosis and treatment.The patient was a 29-year-old unmarried woman who underwent laparoscopic resection of an ovarian lesion in another hospital.Intraoperatively,it was observed that"the right ovary was enlarged with a cauliflower-shaped mass at the lower pole,measuring about 11 cm×8 cm,unencapsulated,with a fish-like texture,which was completely excised and sent for examination."Postoperative consultation with a(tertiary)hospital in Beijing and our pathology department suggested the diagnosis of ovarian adenosarcoma.Therefore,we performed a comprehensive staged surgery for the patient,i.e.,laparoscopic right salpingo-oophorectomy,cystectomy of the left ovary,omentectomy,multiple peritoneal biopsies,and hysteroscopic resection of cervical canal lesions.The patient received four cycles of postoperative chemotherapy with paclitaxel and ifosfamide.After chemotherapy,the patient has been regular followed up and showed no signs of recurrence during the almost 2-year postoperative follow-up period.

Objective To investigate whether the combination of conventional respiratory training and articulatory visual feedback training can improve respiratory function and diaphragmatic function in stroke patients.Methods This single-blind randomized controlled trial recruited a total of 30 stroke patients who were admitted to Department of Rehabilitation Medicine,Zhongshan Hospital,Fudan University,from Nov 2022 to Aug 2023,and divided them into two groups:a experimental group(n=15)and a control group(n=15).The experimental group received conventional respiratory training combined with articulatory visual feedback training,and the control group received conventional respiratory training.The training in the 2 groups was conducted 5 times per week for 4 weeks.Results Both groups significantly improved in maximum inspiratory pressure(MIP),peak inspiratory flow(PIF),maximum phonation time(MPT),maximum counting ability(MCA),and peak expiratory flow(PEF)in each of the two groups improved significantly after training(P<0.05).After training,compared with the control group,the experimental group showed significant differences in MIP[(46.04±13.58)cmH2O vs.(63.46±16.96)cmH2O;P=0.004;95%CI:-28.91,-5.93;effect size(ES)=1.13],PIF[(144.00±43.81)L/min vs.(190.20±75.01)L/min;P=0.049;95%CI:-1.54,0;ES=0.75],MCA[(7.06±3.25)s vs.(10.30±4.89)s;P=0.041;95%CI:-6.34,-0.13;ES=0.77],forced vital capacity(FVC)[(1.74±0.76)L vs.(2.26±0.57)L;P=0.04;95%CI:-1.03,-0.03;ES=0.77],forced expiratory volume in one second(FEV1)[(1.10±0.40)L vs.(1.60±0.50)L;P=0.004;95%CI:-0.85,-0.18;ES=1.1],and PEF[(83.40(55.80)L/min vs.171.12(94.80)L/min;P=0.012)].However,there were no statistically significant differences after training between the two groups in the maximum phonation time(MPT),vital capacity(VC),maximum voluntary ventilation(MVV),diaphragm mobility of the nonparetic side and paretic side,thickening fraction of the nonparetic side and paretic side.Conclusion Compared with conventional respiratory training alone,the combination of articulatory visual feedback training with conventional respiratory training is more effective in enhancing respiratory and lung function in stroke.

Objective:To investigate the effect of TCP1 expression on the proliferation and the accumulation of intracellular drug of HL60/A and HL60 cells and its possible molecular mechanism.Methods:Lentiviral transfection technology was used to construct HL60/A and HL60 cells with knocked down or overexpressed TCP1 and their control cells.The efficiency of knockdown and overexpression was evaluated by Western blot.The cell proliferation was detected by CCK-8 assay.The intracellular drug accumulation was detected by laser confocal detection and flow cytometry.The expression levels of MRP1,P-gP and p-AKT were evaluated by flow cytometry and Western blot.Results:After TCP1 was knocked down,the proliferation ability of HL60/A cells was significantly reduced,the accumulation of intracellular drug was significantly increased and the expression of MRP1 and P-gP protein were decreased.After TCP1 was overexpressed,the proliferation ability of HL60 was significantly increased,the accumulation of intracellular drug was significantly decreased and the expression of MRP1 and P-gP protein were increased.Intervention of LY294002 significantly antagonized the promotion on cell proliferation,the inhibition on intracellular drug accumulation and the expression of MRP1 and P-gP mediated by TCP1 overexpressing in HL60 cells.Conclusion:TCP1 can promote cell proliferation,improve the expression of MRP1 and P-gP by activating PI3K/AKT signal,and reduce intracellular drug accumulation.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
