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.

This article systematically reviews the characteristics and trends of the writing, editing, publication and promotion of physiology textbooks in China from the late 19th century to the present, focusing on the introduction, development and innovation of Chinese physiology textbooks. The development of physiology textbooks in China is divided into four main stages: the introduction and initial development of physiology textbooks from the late 19th century to 1925; the localization and diversification of textbooks from 1926 to 1949, after the establishment of the Chinese Physiological Society; the exploratory phase of textbook construction after the founding of the People's Republic of China from 1949 to 1976; the formation and innovation of the textbook development process from 1977 to the present, following the restoration of the college entrance examination. For each phase, the article not only records the historical development of physiology textbooks, but also analyzes the evolution of their content, writing styles and the interaction with the social and political contexts. The article summarizes the characteristics and experiences of all these four phases. Special attention is given to the comprehensive statistical analysis of physiology textbooks published since the restoration of the college entrance examination and Economic Reform and Opening-up in 1977, revealing the changes in the number, publication trends and academic features of textbooks during this period. Finally, the article presets the future development of physiology textbooks in China, proposing that textbook writing should integrate aspects such as ideological and political education, medical humanities, basic and clinical medicine, health education, scientific research and international exchange and collaboration. The article also advocates for the application of new technologies and methods, such as artificial intelligence, virtual teaching models and knowledge graphs, to support "personalized learning". This research provides a systematic reference for the study of the history of medical education and offers theoretical support for the future innovation of physiology textbook in China.

OBJECTIVE To investigate the changes in serum metabolites of mice with radiation-induced intestinal injury under the intervention of baicalein and the changing characteristics of endogenous biological small molecules during the process of baicalein's participation in the prevention and treatment of radiation-induced intestinal injury through the metabolomics method based on GC-MS technology,in order to explore the potential regulatory mechanism of baicalein.METHODS A mouse radioactive intestinal injury model was established and randomly divided into normal control group,model group,low-dose baicalein group and high-dose baica-lein group.Baicalein was administered by gavage.Gas chromatography-mass spectrometry(GC-MS)technology was used to analyze the serum samples of mice in each group,and differential metabolites were screened through partial least squares-discriminant analysis(PLS-DA).Potential metabolic pathways were analyzed with MetaboAnalyst.RESULTS The pathological sections of mouse intesti-nal tissue showed that the high-dose and low-dose baicalein groups had a certain protective effect on radiation-induced intestinal dam-age.Metabolomic analysis showed that there were significant differences in the metabolic profiles of the blank control group,model group,low-dose and high-dose baicalein administration groups.After intragastric administration of baicalein,the endogenous metabo-lites in mice with radiation intestinal injury tended to normalize.The study screened out a total of 11 potential metabolic markers and 5 related metabolic pathways,among which pathways related to glucose metabolism,glutathione pathway,and ammonia metabolism were particularly significant.CONCLUSION Baicalein has a certain preventive and therapeutic effect on radiation-induced intestinal in-jury;baicalein participates in glucose metabolism and glutathione metabolism,and improving the endogenous substance disorder caused by radiation is its potential mechanism of action.

Objective:To evaluate the initial clinical outcome of applying a comprehensive debulking procedure centered on the digital and plantar flaps with comparatively healthy proximal pedicle to reconstruct the hypertrophic toes and forefoots in one-stage surgery in multiple toes macrodactyly in children.Methods:The clinical data of children with macrodactyly deformity treated by the Department of Burn and Plastic Surgery in Children’s Hospital of Chongqing Medical University from January 2022 to October 2023 were retrospectively analyzed. Design toe and plantar arbitrary flaps with a few vascular perforating branches which pedicle at the comparatively healthy proximal side and resect all tissues beyond the normal length. In severe toe, a composite tissue nail-flap with the artery was dissected to reconstruct the toenail. Fat debulking on the surface of deep plantar fascia as well as within the osseofascial sheath, resecting partially of the fatty infiltrated nerve, transverse and longitudinal osteotomy to shorten and narrowed phalanxes without epiphyseal block, arthroplasty and flexor tendon tightening were performed. Finally, toes shaped by wrapping toe flaps, and pelmas restored by plantar flaps which both with comparatively healthy proximal pedicle. The operation time, healing time, and whether the toes and toenails are preserved were all recorded. The maximum circumference of both foot, the difference in shoe size, the presence of skin ulcers, wound scars, toe webbing morphology, the presence of basic sensation, and the satisfaction of parents were followed-up after surgery. The modified follow-up questionnaire was used to evaluate the surgical effect, the total score is 0-12 points, and the higher the score, the better the surgical outcome. Descriptive methods was used for statistical analysis, and the measurement data conforming to normal distribution were expressed as Mean±SD.Results:A total of 15 patients were enrolled, including 11 males and 4 females. The median age at the time of operation was 2.75 years (0.9-10.8 years). There were 11 cases with 2 toes and 4 cases with 3 toes, a total of 34 toes involved. The average surgical duration was 4.13 hours (3.25 hours for 2 toes and 5.00 hours for 3 toes). Only one severe case with 3 toes involved was amputated the biggest toe ray and totally 2 toe nail flaps were harvested unsuccessfully intraoperative. Except 3 toes had distal skin partially necrosis and 2 nail flaps were completely necrotic which healed after dressing changes, the rest of the toes were healing well after operation. The average follow-up time was 4.8 months (3-11 months), the difference of circumference was less than 1.5 cm, as well as in length was less than 0.5 cm between feet and all children were able to wear the appropriate shoes with same size. A total of 4 toes failed to retain toenails, and 1 had a very thin toenail. Except for one case with insufficient web depth, the other toe webs were close to normal. There was no skin ulcer occurred, the basic sensation of the feet was present, and wound scars were inconspicuous. The score of the modified questionnaire was 10.54±0.88, all parents were satisfied with the results.Conclusion:Comprehensive procedure centered on the digital and plantar flaps with comparatively healthy proximal pedicle for debulking multiple toes macrodactyly in children could completely excise distal hypertrophic tissues in a single operation, and the size of the affected feet and toes can be greatly reduced to wearing shoes of the same size, and have a high success rate in preserving the toes, as well as nails. The reconstructed feet, toes and toe webbing have near-normal morphology, hidden scar, no ulcers after walked and achieve a good initial effect.

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P＜0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.
