OBJECTIVE To investigate the variations in taste， aroma and volatile organic compounds of Rhei Radix et Rhizoma decoction pieces derived from different sources， and to identify their origins. METHODS The flavor， odor and volatile organic compounds of Rhei Radix et Rhizoma decoction pieces from different sources were compared and analyzed by using electronic tongue， electronic nose， and gas chromatography-ion mobility spectrometry （GC-IMS）. Principal component analysis （PCA）， partial least squares-discriminant analysis （PLS-DA）， orthogonal partial least squares discriminant analysis （OPLS-DA） and Fisher discriminant analysis were employed to identify the origins of Rhei Radix et Rhizoma decoction pieces and establish the basis discrimination criteria. RESULTS The differences in taste of Rhei Radix et Rhizoma decoction pieces from 3 origins were primarily characterized by bitterness， astringency， and bitter-astringent aftertaste. In terms of smell， variations were mainly observed in inorganic sulfides， organic sulfides containing aromatic components， methane and other short-chain alkanes， alcohols， ethers， aldehydes and ketones， as well as nitrogen oxides. Differentially volatile organic compounds mainly consisted of alcohols， aldehydes and ketones. Furthermore， the samples from 8 batches could be effectively classified into 3 categories.Three types of Rhei Radix et Rhizoma decoction pieces can be effectivily identified based on the peak intensity ratio between volatile substances. For example， when the peak intensity of 2-acetylfuran was 3-19 times that of isobutyric acid [dimer]， it was considered as Rheum officinale Baill. CONCLUSIONS The discriminant models established in this study， along with the criteria for determining the origins based on the peak intensity ofcharacteristic volatile compounds， can be utilized for the identification of Rhei Radix et Rhizoma decoction pieces.

Chaihu Guizhi Decoction is an excellent prescription of ZHANG Zhongjing;however,nowadays the application of Chaihu Guizhi Decoction is primarily derived from the text.The xiang thinking is the source of traditional Chinese medicine thinking.Understanding Chaihu Guizhi Decoction from the xiang thinking,it is easy to perceive the true meaning of ZHANG Zhongjing,and grasp the location of the disease and the patient's overall qi,so as to make better use of this formula.This article discusses the understanding of Chaihu Guizhi Decoction from five perspectives:firstly,it gives an overview of the xiang thinking,pointing out the source and essential value of the xiang thinking;secondly,it analyses the disease position and the patient's qi of Chaihu Guizhi Decoction under the perspective of the xiang thinking as a whole;thirdly,it discusses the disease position and the patient's qi of the original text of Chaihu Guizhi Decoction from the xiang thinking;fourthly,it discusses how to understand the principle of formula formation and the main and minor parts of Chaihu Guizhi Decoction by xiang thinking;finally,it analyses the primary medicines in Chaihu Guizhi Decoction by using xiang thinking based on the records of Shennong Bencao Jing.Based on these five points,we hope to reveal the traditional Chinese medicine thinking behind Chaihu Guizhi Decoction,and provide new ideas for the clinical application of Chaihu Guizhi Decoction.

This article summarizes the unique viewpoints and experience application of the famous and veteran Chinese medicine practitioner,Professor Wang Xinzhi,in treating emotional diseases from the perspective of gallbladder theory.Based on the physiologi-cal functions and characteristics of the gallbladder in Chinese medicine,it is proposed that the"heart mind-gallbladder-viscera"axis dominates the generation and changes of emotions,and it is believed that gallbladder failure is the key pathogenesis of emotional disor-ders.The treatment of clinical syndromes should be based on the type of gallbladder,and emotional diseases can be divided into types of insufficient gallbladder qi,unfavorable Shaoyang,gallbladder and heat excess,timidity-deficiency,and heart-gallbladder indeci-sion,according to clinical manifestations;based on the basic principle of adjusting the functions of the heart,spleen,liver,gallblad-der,kidney and other organs,treatment methods such as tonifying the spleen and kidneys,increasing gallbladder qi,resolving Shaoy-ang,clearing gallbladder heat,warming yang and replenishing qi,calming the mind,resolving phlegm and removing blood stasis should be used,highlighting the joint treatment of the heart and the gallbladder,and the simultaneous regulation of the liver and gall-bladder,so that the mind can be at ease,the gallbladder can be decisive,and the emotions can be harmonious.

Alzheimer's disease （AD） is a chronic neurodegenerative disorder characterized by the progressive loss of cognitive and memory functions. Its pathological features mainly include neurofibrillary tangles formed by the aggregation of hyperphosphorylated tau proteins and amyloid plaques formed by the accumulation of β-amyloid. The exact pathogenesis of AD has not been fully elucidated， and there are currently no effective specific drugs or radical treatments available in clinical practice. In recent years， the incidence of AD has been on the rise， severely affecting life and health， making the search for effective drugs and therapeutic components for AD treatment crucial. Modern medical research has found that the brain-derived neurotrophic factor （BDNF）/tropomyosin receptor kinase B （TrkB） signaling pathway is closely related to neurogenesis， apoptosis， neuroinflammation， synaptic plasticity， and oxidative stress， playing a vital role in the pathophysiological development of AD. Additionally， Chinese medicine has a long history of treating neurodegenerative diseases with few adverse reactions and features a multi-target， multi-link， and multi-pathway approach to treatment. Therefore， the author reviewed the latest research reports in China and abroad to elaborate on the role of the BDNF/TrkB signaling pathway in the onset and progression of AD， and summarized the research progress on the regulation of the BDNF/TrkB pathway by Chinese medicine compounds and monomers in AD intervention. This study is expected to provide references for the development of clinical drugs for the prevention and treatment of AD and to broaden the perspective on Chinese medicine treatment of AD.

Post-stroke depression is a common complication after a stroke. Based on the theory of ＂deficiency of heart qi leading to sadness＂recorded in Huangdi Neijing, our team proposes that deficiency of heart qi is the basic pathogenesis of post-stroke depression, with sadness being its main manifestation. Therefore, we advocate treating post-stroke depression from the perspective of the heart, and clinically, it can be divided into four stages: heart-liver stage, heart-lung stage, heart-spleen stage, and heart-kidney stage. Treating post-stroke depression with the principle of regulating qi and nourishing the heart, patients in the heart-liver and heart-lung stages are mainly middle-aged and young adults, with a pathological nature of qi stagnation and mild deficiency of heart qi, and therefore, the method of promoting the flow of meridians and regulating qi should be adopted. In contrast, patients in the heart-spleen and heart-kidney stages are mainly middle-aged and elderly, with a pathological nature of qi deficiency and severe deficiency of heart qi, and therefore, nourishment and tonification should be prioritized. In response to the above four stages, our team has achieved good clinical efficacy by administering Xiaoyao Powder, Baihe Dihuang Decoction, Ganmai Dazao Decoction and Jingui Shenqi Pill respectively. This study discusses the approach to treating post-stroke depression from the perspective of a "deficiency of heart qi leading to sadness" by examining three aspects: the theoretical basis of Chinese and Western medicine to treat post-stroke depression from the heart, the basic pathogenesis and staging of post-stroke depression, and the treatment principle of regulating qi and nourishing the heart. The study also briefly analyzes the clinical experience of the medications used for this condition to provide a reference for the treatment of post-stroke depression.

Objective To evaluate postoperative efficacy and safety of oral or nasal feeding Chinese patent medicine in the treatment of intracerebral haemorrhage(ICH)based on Bayesian network meta-analysis(BNMA).Methods The randomized controlled trial(RCT)study of Chinese patent medicine for intervening in post-operative patients of ICH was retrieved from CNKI,Wanfang,VIP,SinoMed,PubMed,Embase,Cochrane Library,and Web of Science.The retrieval time is from the establishment of databases to August 25,2023.ROB 2.0 was used for risk of bias assessments.BNMA was performed by using R 4.2.2 loaded with the BUGSnet 1.1.0 package.Results A total of 28 RCTs were included,with a total sample size of 2 530 cases,including 9 kinds of Chinese patent medicines[Angong Niuhuang Pills(AGNH),Suhexiang Pills(SHX),Naoxueshu Oral Liquid(NXS),Naoxintong Capsules(NXT),Naoxuekang Tablets(NXK),Xiaoyukang Capsules(XYK),Yangxue Qingnao Granules(YXQN),Tongtian Oral Liquid(TT),Sanqi Tongshu Capsules(SQTS)].All patients underwent surgical treatment and postoperative treatment of conventional western medicine(CWMT),the experimental group was additionally given Chinese patent medicine orally or by nasal feeding.The BNMA results showed that AGNH+CWMT group ranked first in reducing short-term mortality,NIHSS score,and perihematomal edema,with P＜0.05 compared to CWMT group.SHX+CWMT group ranked first in improving total effective efficiency,with P＜0.05 compared to CWMT group.TT+CWMT group ranked first in increasing GCS scores,with P＜0.05 compared to CWMT group.YXQN+CWMT group ranked first in improving BI index,with P＜0.05 compared to CWMT group.NXS+CWMT group ranked first in promoting the absorption of cerebral hematoma,with P＞0.05 compared to CWMT group.NXT+CWMT group ranked first in shortening the average length of hospital stay,with P＞0.05 compared to CWMT group.Conclusion Compared with CWMT group,the combined use of Chinese patent medicine and CWMT is effective in improving the total effective rate,reducing mortality and NIHSS score,increasing GCS score and BI after operation in patients with ICH.There is no significant difference in promoting hematoma absorption and shortening the average length of hospital stay.AGNH has good effect,which may be the best Chinese patent medicine in the post-operative treatment of ICH patients.However,due to limitations in quality and methodology of included research,the conclusions obtained still need further validation.

Dermatomyositis, a common autoimmune disease in clinical practice, often involves muscles and lungs, and can be complicated by malignant tumors, and the lung involvement can be fatal. Therefore, early diagnosis and treatment of dermatomyositis is of great benefit for the reduction of muscle and lung injury, early recognition and management of malignant tumors, and improvement of prognosis and survival rate of patients. However, the heterogeneity and various clinical manifestations of dermatomyositis pose challenges to early diagnosis. This article describes risk factors for dermatomyositis complicated by rapidly progressive pulmonary interstitial fibrosis, dysphagia or malignant tumors, and proposes a mode of "rashes + nailfold capillary abnormalities + myositis antibodies" for the early diagnosis of dermatomyositis, early recognition of important visceral injury and tumors, and early management, in order to improve overall survival rate of patients.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Pseudoangioedema, a new type of skin lesions of dermatomyositis, is characterized by localized or diffused, non-pitting, non-pruritic edema on the face, lips, and limbs, with or without erythema. Most dermatomyositis patients with pseudoangioedema are positive for anti-transcriptional intermediary factor 1γ antibodies, and experience severe muscle injuries, increase of serum creatine kinase levels, and refractory dysphagia. A small number of dermatomyositis patients with pseudoangioedema are positive for anti-melanoma differentiation-associated gene 5 antibodies, and have lung involvement. Therefore, high attention should be paid to the occurrence of pseudoangioedema in patients with dermatomyositis, and the screening of specific antibodies can facilitate early diagnosis and differential treatment, as well as improvement in symptoms and survival rates.

Objective:To analyze the relationship between the clinical medical college students' time investment (including study, activities, entertainment and exercise) and general self-efficacy (GSE) in a medical university in Liaoning province, China.Methods:The first-year medical students were asked to participate the survey. Their GSE was measured by using general self-efficacy scale (GSES) in 2018. One year later, the independent variable table was used to investigate the extracurricular activity time, and 683 valid questionnaires were collected. Ordered logistic regression method was used to analyze the correlation between students' extracurricular activities and GSE.Results:Medical students' GSE was positively associated with their time in extracurricular study ( OR = 1.94, 95%CI = 1.49-2.54), volunteer activities ( OR=1.36, 95%CI = 1.01-1.83), and physical activities ( OR = 1.37, 95%CI = 1.01-1.85). However, there was no significant correlation with the time in activities organized by students ( OR = 1.09, 95%CI = 0.79-1.50) or activities organized by school ( OR = 1.15, 95%CI = 0.84-1.59). Furthermore, compared with clinical students of "5+3" year program, the 5-year program clinical students had a stronger correlation between medical students' GSE and the input of extracurricular study time. Conclusion:There is a positive correlation between medical students' GSE and their extracurricular time investment, which indicates that increasing medical students' GSE could be an effective method to improve their extracurricular time investment and eventually improve their comprehensive quality.
