In recent years,significant breakthroughs have been achieved in the immunotherapy for Alzheimer's disease.In line with global advancements,two anti-amyloid-β monoclonal antibodies have been approved and successfully launched in China for clinical use.Lecanemab and Donanemab were officially used in June 2024 and April 2025 in China,respectively.In order to standardize the rational and safe application of anti-amyloid-β monoclonal antibodies for Alzheimer's disease in China,this article integrates recom-mendations from the clinical trials and real-world experience from the author's team and domestic peers to further update the recom-mendations for the clinical use of anti-amyloid-β monoclonal antibody based on the 2024 version.It includes indications for therapy,pre-treatment evaluation and preparation,administration protocols and safety measures during treatment,and post-treatment monitor-ing strategies.

This study aims to determine the nephrotoxic effects of 3-monochloropropanel-1,2-diol(3-MCPD)on female and male SD rats.A nephrotoxicity model was established by gavage of dif-ferent doses of 3-MCPD,and 80 SD rats were randomly divided into four groups:the control group(0 mg/kg 3-MCPD),low-dose group(15 mg/kg 3-MCPD),medium-dose group(30 mg/kg 3-MCPD),high-dose group(60 mg/kg 3-MCPD),with half female and half male.The body mass and food intake of the rats were recorded weekly,and the urine and blood and kidney tissues were col-lected after 28 consecutive days of gavage,and the blood erythrocyte count(WBC),white blood cell count(RBC),hemoglobin(HGB),erythrocyte-compaction-transfer-value(HCT),creatinine(CREA),serum urea nitrogen(BUN),and the indexes of blood phosphorus(P)and calcium(Ca)were detected;the level of kidney injury molecule(KIM-1)was measured by ELISA kit;the renal pathological changes was observed by histopathology method;and transcriptome sequencing was used to analyze differential genes in female and male rats.The results showed that 3-MCPD did not significantly affect the growth of male rats,but high doses significantly reduced the weight and food intake of female rats.The high-dose group of 3-MCPD caused a significant decrease in RBC,HGB,and HCT levels in both male and female rats,resulting in a significant increase in KIM-1 and P,and a significant decrease in Ca,but only a significant increase in CREA and BUN in female rats.Histopathology showed that in the high-dose group of male rats,only mild renal tubular dilation,epithelial cell edema,and clear tubular type were observed in the kidneys,while in female rats,a large number of renal sacs,clear tubular type,and interstitial inflammatory cells with fibrosis were observed in the kidneys.Transcriptome sequencing showed 1 712 differentially expressed genes in the high-dose group of female rats and 1 153 differentially expressed genes in the high-dose group of male rats.KEGG enrichment analysis showed that both male and female rats in the high-dose group experienced oxidative stress and cell apoptosis,but 3-MCPD may also participate in the process of kidney damage in females by inhibiting autophagy and inducing iron death pathways.The above results indicate that high-dose 3-MCPD has a more significant nephrotoxic effect on fe-male rats.

Objective:To explore the research status and hotspots of enhanced recovery after surgery (ERAS) in China by means of bibliometrics.Methods:Based on the Web of Science, the original researches related to ERAS published by Chinese scholars from January 1, 2000 to December 31, 2020 were retrieved and screened. The annual number of publications and citations, distribution of authors, institutions, provinces, journals published and cited, operations and keywords applied, study design, and level of evidence were analyzed.Results:A total of 297 articles were included, and the number of annual publications and citations showed a significant upward trend. Wang was a high-volume author, and Jiang was a high-volume corresponding author, and Kehlet was a highly cited author in the bibliography. Zhejiang University, Sichuan University, and Nanjing University were high-volume institutions, and Jiangsu, Zhejiang, and Sichuan were high-volume provinces. British Journal of Surgery was a highly cited journal. ERAS was most commonly used in colorectal surgery, the most frequently occurring keywords were colorectal surgery, gastric cancer and laparoscopy. Key words that frequently appeared in recent years included total knee arthroplasty, lung cancer, length of stay, postoperative complications, nursing, elderly and quality of life. The most common study designs were randomized controlled trials, followed by retrospective case-control studies. Among the published studies, the second-level evidence and the fourth-level evidence were the most, and the number of citations of the second-level evidence was significantly higher than that of the fourth-level evidence, and the difference was statistically significant ( P<0.01) . Conclusions:Knee replacement, lung surgery, length of stay, postoperative complications, nursing, elderly, quality of life and so on are the contents of high concern in the original research of ERAS in China in recent years. Prospective, high-level studies should be carried out in the future.

Objective:To compare the efficacy of open surgery and arthroscopic assisted surgery in treatment of knee dislocations.Methods:A retrospective case-control study was conducted to analyze the clinical data of 80 patients with knee dislocations admitted to Second Hospital of Lanzhou University from May 2013 to September 2019, including 59 males and 21 females, aged 18-66 years [(42.5±11.6)years]. Open multiple ligament reconstruction was performed in 49 patients (open group) and arthroscopic assisted multiple ligament reconstruction was performed in 31 patients (arthroscopic group). The postoperative hospitalization days, incidence of complications, time needed for recovery of knee range of motion (>0°, >90°, >120°), and time to complete weight-bearing were compared between the two groups. The Lysholm score, international knee documentation committee (IKDC) subjective knee form, Tegner activity level, score of the MOS item short-form health survey (SF-36), patient satisfaction and knee range of motion were compared between the two groups at the last follow-up.Results:All the patients were followed up for 1.2-7.4 years [(3.8±1.5)years]. There was no significant difference in postoperative hospitalization days or incidence of complications between the two groups ( P>0.05). No significant difference was found in time needed for recovery of knee range of motion (>0°, >120°) or time to complete weight-bearing ( P>0.05). The time needed for recovery of knee range of motion (>90°) was 90(60, 90)days in open group and 60(30, 90)days in arthroscopic group ( P<0.05). At the last follow-up, there was no significant difference in Lysholm score, IKDC subjective score, Tegner activity level, SF-36 score, or patient satisfaction between the two groups ( P>0.05). At the last follow-up, the knee range of motion was 120°(90°, 130°) in open group and 135°(120°, 140°) in arthroscopic group ( P<0.05). Conclusion:For treatment of knee dislocations, open surgery and arthroscopic assisted surgery have similar results in the long-term effect, while arthroscopic assisted surgery has benefits in early rehabilitation and ultimately better knee range of motion.

The existing doctor-patient communication pattern often falls prey to insufficient informed consent and even medical disputes. In the patient centered perspective, Zhejiang Provincial People′s Hospital explored a new communication mode centering on patients. Based on diagnosis-related groups catalogues and high-frequency surgeries catalogues of the departments, multimedia technology was called into play to produce dubbed PPTs and videos that were easy to understand, standardized and homogeneous, which were embedded into medical records system. Following observation of the PPT or video, patients could directly sign an informed consent on the computer. This practice not only deepens patient′s understanding and achieves homogeneous level of the communication, but also elevates doctor′s work efficiency, contributing to building a harmonious doctor-patient relationship.

The liver is the metabolic center of mammalian body. Systematic study on liver's proteome expression under different physiological and pathological conditions helps us understand the functional mechanisms of the liver. With the rapid development of liquid chromatography tandem mass spectrometry technique, numerous studies on liver physiology and pathology features produced a large number of proteomics data. In this paper, 834 proteomics experiments of mouse liver were systematically collected and the mouse liver proteome database (Mouse Liver Portal, http://mouseliver.com) was established. The Mouse Liver Portal contains the liver's proteomics data under different physiology and pathology conditions, such as different gender, age, circadian rhythm, cell type and different phase of partial hepatectomy, non-alcoholic fatty liver. This portal provides the changes in proteins' expression in different conditions of the liver, differently expressed proteins and the biological processes which they are involved in, potential signal transduction and regulatory networks. As the most comprehensive mouse liver proteome database, it can provide important resources and clues for liver biology research.

Objective:To determine the clinical efficacy of posterior intervertebral surgery for single-segment thoracolumbar spinal tuberculosis.Methods:Clinical data were retrospectively analyzed in 62 patients with thoracolumbar spinal tuberculosis who underwent posterior intervertebral surgery (A group) or posterior and anterior combined intervertebral surgery (B group) from January 2010 to January 2015 in Department of Spinal Surgery,General Hospital,Ningxia Medical University.The operative time,blood loss,length of hospital stay,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) level,neurological function,VAS score,vertebral Cobb angle,bone healing,and postoperative complications were compared between the 2 groups.Results:All patients were followed up for 10 to 30 (average 22) months after the operation.In the A group,operative time,blood loss,and hospital stay were less than those in the B group (P＜0.05).In the follow-up,the pain of patients was alleviated and nervous function was improved obviously in the 2 groups compared with pre-operation.The ESR and CRP at the 6 months after operation returned to the normal range in patients of the 2 groups.There were significant differences in the ESR and CRP among the pre-operation,the 6 months after operation,and the end of follow-up within the group (P＜0.05),while there were no significant differences in ESR and CRP between the 6 months after operation and the end of follow-up (P＞0.05).There were no significant differences in the ESR and CRP among the pre-operation,the 6 months after operation,and the end of follow-up in the 2 group (P＞0.05).The Cobb angles after the operation and the end of follow-up were significanthy smaller than those before the operation (P＜0.01),while there were no significant differences in Cobb angle before operation,after the operation,and the end of follow-up between the 2 groups (P＞0.05).There were no significant differences in the bone healing rate at 6 months or 1 year after operation between the A group and B group (P＞0.05) and the complication rate of the A group was lower than the B group (P＜0.01).Conclusion:Clinical efficacy of posterior intervertebral surgery is satisfatory in treating single-segment thoracolumbar spinal tuberculosis with less complications.

Aim To investigate the effects of Naotai formula extract(NTE)on the expression of heme oxygenase-1(HO-1) and hephaestin(Heph) in hippocampus of rats after cerebral ischemia/reperfusion by Keap1-Nrf2/ARE signaling pathway.Methods Eighty rats were randomly divided into five groups as follows: sham operation group(Sham), cerebral ischemia/reperfusion group(I/R), low dose group of NTE(4.5 g·kg-1), middle dose group of NTE (9 g·kg-1) and high dose group of NTE(18 g·kg-1).Rats were pretreated by intragastric administration for three consecutive days, and then subjected to middle cerebral artery occlusion (MCAO) 2 hours before reperfusion.The rats were administered with intragastric administration for two days.After cerebral ischemia reperfusion 72 hours, the behavioral activity of rats was recorded by Zea Longa neurological score, and the infarct volume was measured by TTC staining.The expressions of Nrf2, HO-1 and Heph in hippocampus of cerebral ischemia reperfusion rats were observed by real-time quantitative PCR and Western blot, respectively.Results Compared with model group, the neurobehavioral scores significantly decreased in NTE high-dose and middle-dose groups (P<0.01);the infarct volume of NTE groups markedly decreased (P<0.01);the expression of HO-1 mRNA apparently increased (P<0.05) in NTE groups;the expression of Heph mRNA significantly increased in NTE middle-dose and high-dose groups (P<0.05);the expression of Nrf2 and Heph protein evidently increased in the NTE middle and high dose groups (P<0.05, P<0.01);and the expression of HO-1 protein also increased in NTE groups(P<0.01).Conclusions Naotai formula can relieve cerebral ischemia-reperfusion injury.The mechanism might be associated with activating Keap1-Nrf2/ARE signaling pathways, promoting HO-1 generation, advancing the expression of Heph, and then reducing brain iron deposition, to achieve the protection of neurons after cerebral ischemia-reperfusion.
