Objective Observing the feasibility of acute endovascular treatment for patients with symptomatic anterior intracranial atherosclerotic severe stenosis.Method From Jun 2019 to Jun 2023,30 symptomatic anterior intracranial atherosclerotic severe stenosis cases were retrospectively collected in the Guangdong Hospital of Traditional Chinese Medicine to evaluate the risk stratification score and explore the safety and effectiveness of acute(≤72.0h)endovascular treatment.Endovascular treatment includes balloon dilation+self-expanding stent placement,balloon-mounted stent placement,and balloon dilation.From the clinical experience,the risk stratification score was based on the ABCD3-I score for transient ischemic attacks(TIA)and additional evaluation of cerebral watershed infarction to identify the risk of stroke progression or recurrence in acute stage of symptomatic intracranial artery stenosis.The score of 0-3 was defined as low-risk,4-7 as medium risk,and 8-13 as high-risk.The successful revascularization of blood flow is determined based on the residual stenosis≤50％and the extended thrombolysis in cerebral infarction(eTICI)＞2c.The information of patient receiving endovascular treatment was recorded,including age,sex,risk factors of cerebrovascular disease(hypertension,diabetes,hyperlipidemia,hyperhomocysteinemia,drinking history,smoking history),onset data(time from onset to endovascular treatment,symptoms,progression),diseased vessels,risk stratification score,National Institutes of Health Stroke Scale(NIHSS)score before and 90 days after surgery,modified Rankin scale(mRS)score 90 days after surgery,intraoperative cerebrovascular events(intracranial hemorrhage,occlusion of responsible vessels),and postoperative cerebrovascular events 90 days after surgery(intracranial hemorrhage,cerebral infarction,TIA and in-stent restenosis)and deaths.Results Among 30 patients with symptomatic anterior intracranial atherosclerotic severe stenosis,3 patients were excluded from the time interval between onset and endovascular treatment＞72.0 hours,1 patient needed long-term anticoagulant drugs due to other diseases,1 patient lost follow-up,3 patients coexisted with other cardiogenic cerebral embolism diseases,4 patients with non-atherosclerotic arterial stenosis,and 7 patients refused emergency endovascular treatment.11 patients were finally included.(1)All 11 patients were successfully treated with endovascular treatment,and 7 were males;age ranged from 52 to 76 years old,with a median age of 64 years old;there were 9 cases with hypertension,3 cases diabetes,7 cases hyperlipidemia,2 cases hyperhomocysteinemia(only 9cases performed the examination),2cases smoking history,1 case drinking history;time from onset to endovascular treatment is 4.0-72.0 h,with a median time of 12.0 h;there were 3 and 8 cases of infarction in the left and right hemispheres,respectively,with 4,3,and 2 cases accompanied with anterior-posterior watershed,medial watershed,and anlerior-medial-posterior watershed infarctions,and 1 case accompanied by posterior-medial,anterior-medial watershed infarctions.(2)Among the 1 1 patients,the risk stratification score was 10-13 points,with a median score of 11 points;preoperative NIHSS score ranged 0-11 points,with a median score of 7 points.(3)Among the 1 1 patients,10 lesions located in the middle cerebral artery and 1 in the C7 segment of the internal carotid artery;the preoperative stenosis rate was 70％to 99％,with a median stenosis rate of 86％;preoperative eTICI grading was 2a in 7 cases and 2b50 in 4 cases(with slow distal blood flow);9 cases received balloon dilation and self-expanding stent placement,1 case received balloon-mounted stent placement,and 1 case received balloon dilation treatment;the postoperative stenosis rate is 10％to 20％,with a median stenosis rate of 15％;there were 3 cases with postoperative eTICI grade 2c and 8 cases with grade 3.(4)Among the 11 patients,one experienced intracranial hemorrhage on the first day after surgery and one had a new cerebral infarction on the third day after surgery.Eight patients were followed up by imaging 90days after surgery,demonstrating 2 cases of in-stent restenosis;90 days post-surgery,NIHSS score was 0-20 points,with a median score of 2 points;after 90 days of surgery,the mRS score was 0-4 points,with a median score of 1 point.There were 8 patients with mRS score ≤ 2 and no death events occurred.Conclusions Preliminary analysis shows that acute endovascular treatment for symptomatic anterior intracranial atherosclerotic severe stenosis has certain effectiveness,but the safety needs to be further validated.The screening of high-risk patients using risk stratification scores still requires further exploration through large sample and multicenter studies.

Dementia in traditional Chinese medicine （TCM） mainly presents amnesia and dullness. Alzheimer's disease and vascular dementia belong to the category of dementia in TCM. These progressive neurological diseases have a complex etiology and a long course， and the drugs that can reverse the disease course remain to be developed. Therefore， early intervention plays a vital role in delaying the disease progression. Apathy refers to a lack of motivation that leads to the attenuation or disappearance of goal-directed behaviors， cognitive functions， and emotional responses. Clinical studies have suggested that apathy exists in the early stage of a variety of neurodegenerative diseases， being one of the key symptoms to the early diagnosis of dementia. The severity of apathy is related to the severity of dementia. Therefore， early diagnosis and treatment of apathy are of great significance to the prevention and treatment of dementia. The preclinical research on apathy in dementia is still in its infancy， and the systematic evaluation method has not been prescribed. The clinical diagnosis and treatment are also in the exploratory stage， and the complex pathophysiological mechanisms of apathy and dementia development have not been fully elucidated. This article reviews the research progress of apathy in dementia， the apathetic behaviors of dementia animal models， the behaviors of patients with apathy， and the treatment methods in recent years and summarizes the research status of apathy in dementia. This review aims to provide a theoretical basis for exploring the behavior of apathy in dementia and conducting preclinical research and evaluation of the pathogenesis and to lay a foundation for the treatment of apathy in dementia.

Traditional Chinese medicine （TCM） has a long history of application in China and has consistently played a vital role in treating diseases and saving lives. TCM prescriptions （compounds） constitute the primary form of clinical TCM treatment and significantly differ from western medicine （chemicals） due to the diverse composition and chemical constituents of TCM （compounds）. Nevertheless， the potential multi-component， multi-target， and multi-pathway action characteristics of TCM prescriptions also demonstrate their possible （complementary） therapeutic advantages when compared with single-component chemical drugs. Therefore， driven by the development of modern science and technology and the demands of the modernization and internationalization of TCM， modern theories regarding the complexity of TCM prescription effects have been continuously proposed： Different from the abstract language of traditional prescription theory， the modern TCM prescription theory is more inclined to illustrate the connotation of prescription compatibility concretely and vividly from an experimental and scientific perspective. In this paper， new theories on the complexity of TCM prescriptions proposed in recent years are summarized to provide research references and ideas for the greater role of TCM prescriptions and a better scientific understanding.

ObjectiveTo investigate the effects of Jiaohong pills （JHP） and its prescription， Pericarpium Zanthoxyli （PZ） and Rehmanniae Radix （RR） cognitive dysfunction in scopolamine-induced Alzheimer's disease （AD） mice and its mechanism through pharmacodynamic and metabolomics study. MethodThe animal model of AD induced by scopolamine was established and treated with PZ， RG and JHP， respectively. The effects of JHP and its formulations were investigated by open field test， water maze test， object recognition test， avoidance test， cholinergic system and oxidative stress related biochemical test. Untargeted metabolomics analysis of cerebral cortex was performed by ultra-performance liquid chromatography-Quadrupole/Orbitrap high resolution mass spectrometry （UPLC Q-Exactive Orbitrap MS）. ResultThe behavioral data showed that， compared with the model group， the discrimination indexes of the high dose of JHP， PZ and RR groups was significantly increased （P<0.05）. The staging rate of Morris water maze test in the PZ， RR， high and low dose groups of JHP was significantly increased （P<0.05， P<0.01）， the crossing numbers in the PZ， JHP high and low dose groups were significantly increased （P<0.05， P<0.01）； the number of errors in the avoidance test were significantly reduced in the PZ and high-dose JHP groups （P<0.01）， and the error latencies were significantly increased in the JHP and its prescription drug groups （P<0.01）. Compared with the model group， the activities of acetylcholinesterase in the cerebral cortex of the two doses of JHP group and the PZ group were significantly increased （P<0.05， P<0.01）， and the activity of acetylcholinesterase in the high-dose JHP group was significantly decreased （P<0.05）， and the level of acetylcholine was significantly increased （P<0.01）. At the same time， the contents of malondialdehyde in the serum of the two dose groups of JHP decreased significantly （P<0.05， P<0.01）. The results of metabolomics study of cerebral cortex showed that 149 differential metabolites were identified between the JHP group and the model group， which were involved in neurotransmitter metabolism， energy metabolism， oxidative stress and amino acid metabolism. ConclusionJHP and its prescription can antagonize scopolamine-induced cognitive dysfunction， regulate cholinergic system， and reduce oxidative stress damage. The mechanism of its therapeutic effect on AD is related to the regulation of neurotransmitter， energy， amino acid metabolism， and improvement of oxidative stress.

Demyelination of the central nervous system often occurs in neurodegenerative diseases， such as multiple sclerosis （MS）. The myelin sheath， a layer of myelin membrane wrapping the axon， plays a role in the rapid conduction and metabolic coupling of impulses for neurons. The exposure of the axon will lead to axonal degeneratio， and further neuronal degeneration， which is the main cause of dysfunction and even disability in patients with demyelinating neurodegenerative diseases. In addition to the demyelination of mature myelin sheath， remyelination disorder is also one of the major reasons leading to the development of the diseases. The myelin sheath is composed of oligodendrocytes （OLs） derived from oligodendrocyte progenitor cells （OPCs） which are differentiated from neural stem cells （NSCs）. The process of myelin regeneration， i.e.， remyelination， is the differentiation of NSCs into OLs. Recent studies have shown that this process is regulated by a variety of genes. MicroRNAs， as important regulators of neurodegenerative diseases， form a complex regulatory network in the process of myelin regeneration. This review summarizes the main molecular pathways of myelin regeneration and microRNAs involved in this process and classifies the mechanisms and targets. This review is expected to provide a theoretical reference for the future research on the treatment of demyelinating diseases by targeting the regulation of microRNAs.

Objective To investigate the application value of type Ⅰ procollagen N-peptide front-end (PⅠNP) in growth and development in children.Methods The clinical data of 99 children visiting in the ped-iatric department of Guangdong Provincial Hospital of Traditional Chinese Medicine from March to August 2023 were analyzed retrospectively,including gender,age,height,weight,BMI,visiting season,Tanner stage,PⅠNP,β-collagen degradation product (β-CTx),N-terminal osteocalcin (N-MID).The general data of children with different sex and PⅠNP level were analyzed.The partial correlation between PⅠNP and growth rate was analyzed.Then the efficiency of PⅠNP for predicting the child growth rate slow was conducted by the receiver operating characteristic (ROC) curve.Results The children height standard deviation,Tanner stage,β-CTx,N-MID,height after blood drawing,growth rate after blood drawing,growth rate slowness had statistical difference among the children with different PⅠNP levels (P<0.05).In the partial correlation,PⅠNP has the correlation with β-CTx (r=0.671),N-MID (r=0.506),growth rate before blood drawing (r=0.551) and growth rate after blood drawing (r=0.474,P<0.05).In linear regression,PⅠNP was linearly correlated with children's height growth rate,and the greater the PⅠNP value was,the higher the children's height growth rate in the past or the next three months was likely to be (P<0.05).The ROC curve results showed that when PⅠNP<434.8 ng/mL,there was a risk of slow height growth rate in children (AUC was 0.819,95%CI:0.712-0.927,sensitivity was 80.0%,specificity was 78.6%).Conclusion The PⅠNP level could reflect the height growth rate of children in the past or the next three months in their daily life,and has certain predictive value for the slow growth rate of children.

Objective To Investigate the effect of copper ions on the radiosensitivity of nasopharyngeal carcinoma(NPC)and identify potential targets to improve the efficacy of NPC radiation therapy.Methods The content of copper ions in normal nasopharyngeal epithelial cell line NP69 and a variety of NPC cell lines was detected by a copper microplate assay.After adding 0,5,10,20,50,100,200 μmol/L copper ion solution and 0,0.05,0.1,0.2,0.5,1.0,2.0 mmol/L TEPA solution,CCK-8 assay was used to determine the effect of intracellular copper ion content on the survival rate of NPC cells before and after irradiation.And determine the drug concentration to be used in subsequent experiments.CCK-8 assay was used to determine the effect of intracellular copper ion content on the survival rate of NPC cells before and after irradiation,and to determine the drug concentration used in the copper ion group and TEPA group in the subsequent experiments.CCK-8 assay and clone formation assay were used to detect the changes in radiosensitivity of NPC cells after drug treatment.The DNA damage and MAPK-ERK signaling pathway-related protein expression of NPC cells in each group before and after irradiation were detected by Western blot.Results The content of copper ions in NPC cells was significantly higher than that in normal naso-pharyngeal epithelial cells(P＜0.05).When the concentration of copper ion solution was lower than 50 μmol/L,the radiation resistance of CNE1 cells was improved,and the radiation sensitivity of SUNE1 cells was increased by 0.1～0.2 mmol/L TEPA(P＜0.05).Compared with the control group,the NPC cell radiotherapy resistance of copper ion group was enhanced,and the NPC cell radiotherapy sensitivity of copper ion group was enhanced(P＜0.05).Compared with the control group,the activation degree of MAPK-ERK pathway in copper ion group was up-regulated(P＜0.05).MAPK-ERK pathway inhibitor SCH772984 effectively reversed copper-mediated NPC radiotherapy resistance(P＜0.05).Conclusion The increased copper ion content in NPC cells promoted the radiotherapy resistance of NPC cells by activating the MAPK-ERK signaling pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective To explore the biological indicators of diagnosis and treatment of irritable bowel syndrome (IBS), and to explore the mechanism of action of a Chinese medicine Wuji Pill (WJW) on irritable bowel syndrome (IBS). Methods (1) Postinflammatory irritable bowel syndrome (PI-IBS) rat model was established by acetic acid plus restraint stress method . (2) The colonic motor ability of rats was evaluated by colon motility index (MI), the number of fecal particles discharged within 2 h, and the time of glass pellet discharge. (3) The formation of PI-IBS model rats and the therapeutic effect of WJW were observed. (4) The levels of calcitonin gene-related peptide (CGRP), motilin (MTL), neuropeptide Y (NPY), substance P (SP), somatostatin (SS), vasoactive intestinal peptide (VIP), and cholecystokinin (CCK) in the brain and colon tissues of PI-IBS rats were measured by ELISA. Results (1) The rat PI-IBS model was successfully established. Compared with the normal group, the body weight of the model rats was decreased, the food intake decreased, the amount of feces increased, loose stools and amorphous soft stools appeared, voluntary movements decreased, colon motility index ( MI) significantly increased ( P ＜ 0. 05 ), the number of fecal particles discharged significantly increased ( P＜ 0. 05), and the glass pellet discharge time was significantly shortened ( P ＜ 0. 05). (2) WJW treatment for 7 days significantly improved a variety of symptoms. Compared with the normal control, the levels of CGRP, SS and VIP in the brain tissue of PI-IBS rats were significantly increased (P＜ 0. 05), and the NPY concentration was significantly decreased ( P ＜ 0. 05). However, the treatment with WJW significantly reduced CGRP, SS and VIP levels (P＜ 0. 05), and significantly increased the NPY concentration level (P ＜ 0. 05). (3) Compared with the normal control group, the levels of CCK, NPY, MTL, SS and VIP in colonic tissues of PI-IBS rats were significantly decreased (P＜ 0. 05), while WJW significantly increased the CCK and VIP levels. Conclusions WJW can be used to treat IBS by regulating the levels of various brain-gut peptides in the brain and colon tissues of IBS rats. These anomalous and adjustable brain-gut peptides may become a potential biomarker for the diagnosis and treatment of IBS.
