Traumatic brain injury(TBI)is mostly caused by motor vehicle traffic accidents or competitive sports,with high mortality and disability.TBI mainly includes primary injury and secondary injury.Primary injuries were caused directly by external forces.Secondary injuries include brain edema,excitotoxic effect of neuron cells,oxidative stress and neuroinflammation,etc.Effective intervention of secondary injury not only helps to improve the prognosis of patients with TBI,but also reduces the risk of Parkinson's disease and other neurodegenerative diseases related to TBI.Autophagy is one of approaches to regulate homeostasis in cells,and autophagy dysfunction has been found in several neurodegenerative diseases and TBI.It is speculated that autophagy dysfunction may play an important role in TBI and explain why patients with TBI have higher risk of neurodegenerative disease.Discovering the role of autophagy in the pathological mechanism of TBI may provide new targets for TBI clinical treatment and cognitive impairment prevention in patients with TBI.

Objective To design and construct chimeric antigen receptor(CAR)T cells targeting Trop2,establish an in vitro cell exhaustion model through continuous antigen stimulation,and investigate their anti-tumor activity and exhaustion characteristics.Methods The second-generation CAR plasmid was constructed based on the single-chain variable fragment(scFv)sequence of Sacituzumab Govitecan targeting Trop2.The viral vector titer was determined by retroviral vector packaging and gradient dilution.Peripheral blood mononuclear cells(PBMCs)from healthy donors were isolated using Ficoll density gradient centrifugation,and CAR virus vectors were transduced into PBMCs activated with OKT-3/IL-2 to generate Trop2-targeted CAR T cells.CAR expression levels were assessed by flow cytometry using MYC tags.In vitro 3 tumor cell models were established,including human ovarian cancer cells(SKOV3),human breast cancer cells(MDA-MB-453),and human lung cancer cells(A549).The expression of the Trop2 antigen in these models was confirmed using flow cytometry.Additionally,luciferase assay was employed to evaluate the cytotoxic efficiency of Trop2-targeted therapy at various effector-to-target ratios.An in vitro CAR-T exhaustion model was developed,and the long-term killing ability of CAR-T cells was dynamically monitored using the Incucyte live-cell imaging system.The PD-1/TIM-3 phenotype of CAR-T cells was analyzed by flow cytometry,and cytokine secretion levels were quantified using the cytometric bead array(CBA).Transcriptomic sequencing and RT-qPCR were employed to validate the differentially expressed genes associated with exhaustion.Results The second-generation CAR T cells targeting Trop2 were successfully constructed.Compared to the P-T group,in vitro experiments demonstrated that these CAR T cells exhibited antigen-specific and dose-dependent cytotoxic effects against tumor cells with high Trop2 expression,such as MDA-MB-453 and SKOV3.A CAR-T cell exhaustion model established through repeated tumor antigen stimulation in vitro revealed that,compared to the initial state,the exhausted Trop2 CAR-T cells exhibited significantly reduced tumor-killing capacity while P-T cells showed almost no killing effect,the expression of inhibitory receptors(PD-1 and TIM-3)was up-regulated on the surface of exhausted CAR-T cells,and the secretion of effector cytokines was diminished.Transcriptomic analysis identified multiple differentially expressed genes in the exhausted CAR-T cells.Pathways related to immune response and T cell receptor signaling were down-regulated,while apoptosis-related pathways were activated.RT-qPCR further confirmed abnormal expression of immunoregulatory genes,including IL3,IL5,and IL13(P<0.05).Conclusion During continuous in vitro tumor antigen stimulation,the second-generation CAR-T cells targeting the Trop2 antigen demonstrate declined anti-tumor activity,weakened effector function and up-regulated expression of exhaustion-related molecules.

Cardiovascular diseases(CVD)are chronic disease with high morbidity and mortality in the world.Pinellia ternatais a traditional Chi-nese medicinal herb and has the effects on drying dampness,resolving phlegm,lowering symptoms,stopping vomiting and relieving swelling.In recent years,researches showed that Pinellia ternataand its active ingredients(β-sitosterol,baicalin,baica-lein,quercetin)had significant effects in the treat-ment of cardiovascular diseases.This review sum-marized and analyzed the role and mechanism of Pinellia ternata and its active ingredients in cardio-vascular diseases,which provided a theoretical ba-sis for its clinical application.

During the period of the Republic of China, acupuncture faced different opportunities and developments in China and the West. The correspondence between Soulié de Morant, the father of European acupuncture, and FANG Shen'an, a famous acupuncture master of the Republic of China, is of great significance to explore the exchange of acupuncture between China and France, the development of acupuncture in France, the Western learning of Chinese medicine, and the dissemination of academic ideas of acupuncture in the Republic of China. The authors studied Soulié de Morant's collection stored in the Museum of Western Studies of Chinese Medicine of Yunnan University of Chinese Medicine, and found Soulié de Morant's annotation of Jinzhen Mizhuan (Secrets of Golden Needle), the 1937 edition, and 3 paper letters with FANG Shen'an (2 letters in French and 1 letter in Chinese). After the language translation and collation, based on the correspondence between two masters, in association with the historical background and the narration of CHEN Yemeng, the inheritor of Fang's acupuncture, this paper reviews the process of academic exchanges between them, so as to display the historical development of acupuncture in China and the West.

In 1929, George Soulié de Morant and Paul Ferreyrolles co-authored their first acupuncture-moxibustion paper titled "L' Acuponcture en Chine vingt siècles avant J.-C. et la réflexothérapie moderne", greatly advancing the development of acupuncture-moxibustion in Europe. Their paper systematically explains the holistic view and the concept of yin-yang balance in traditional Chinese medicine, describes the techniques of acupuncture and moxibustion, innovatively classifies acupuncture-moxibustion as "reflexotherapy", organizes the effects of certain acupuncture points illustrated on human acupoint atlas; and for the first time, it summarizes the correspondence between acupuncture points and Weihe trigger points. In the historical background of the neo-Hippocratic movement, they used the existing theories at that time to explain acupuncture, and adopted the analogical medicine to explore the mechanisms of acupuncture-moxibustion, which gradually initiated the modern era of acupuncture-moxibustion in France. Such research method is conducive to reducing the unfamiliarity of acupuncture-moxibustion among westerners, deepening their understanding of its theories and therapeutic effect, and also integrating it with other medical research. It breaks through the limitations of traditional theories and obtains the self-improvement and progress.

During the mid-20th century, Dr. Paul Ferreyrolles played an important role in the dissemination of acupuncture in France. He keenly recognized the unique value of the acupuncture knowledge brought from China by Soulié de Morant, devoted himself to its practice and research, and attempted to interpret its principles through western knowledge. From Ferreyrolles' experiences and contributions, three key factors can be identified for the successful spread of acupuncture in Europe: the availability of comprehensive translated texts, the broad recognition of therapeutic efficacy, and the adaptation and interpretation of acupuncture in western terms.

Guided by the theory of "fire and original qi are restricted"， it is believed that original qi depletion is the root of the cutaneous immune-related adverse events （cirAEs） related to immune checkpoint inhibitors （ICIs）， and the yin fire exuberance is the branch. Among them， original qi depletion is the internal foundation of the disease， while the drug toxicity of ICIs harming original qi is the initiating factor， and exuberant yin fire is the key pathogenesis. In clinical practice， the general treatment principle advocates banking up original qi to consolidate the root and draining fire to raise yang. Buzhong Yiqi Decoction （补中益气汤） can be used to activate transportation of middle jiao （焦） and promote ascent and dispersion of clear yang， thereby restoring the balance of qi and fire， and medicinals such as Huangqin （Radix Scutellariae）， Huanglian （Rhizoma Coptidis） and Huangbai （Cortex Phellodendri Chinensis） can be supplementetd to clear and drain yin fire. At the same time， considering the accompanying symptoms such as dampness-stasis and fluids depletion， the methods of removing dampness and dispelling stasis， supplementing blood and nourishing yin should be added flexibly. This approach can provide a new perspective and treatment strategy for reducing ICIs-related cirAEs in malignant tumors.

Pulmonary complications， the most common postoperative complications of lung cancer， not only affect the quality of life of the patients after surgery but also increase the prognostic risks of postoperative recurrence and metastasis， threatening the life safety. At present， a multidisciplinary model of diagnosis and rehabilitation with integrated traditional Chinese medicine （TCM） and Western medicine has been initially formed under the guidance of the concept of rapid rehabilitation post operation for lung cancer. However， the treatment that only aims at shortening hospital stay and reducing the incidence of postoperative complications does not pay enough attention to the postoperative functional rehabilitation of the lung and the impact of follow-up adjuvant therapy， which affects the completeness of rehabilitation. This paper classifies the typical postoperative symptoms and manifestations of lung cancer into five groups： Lung system， emotion， digestive tract， pain， and nerve. On this basis， this paper summarizes the three core pathogeneses of postoperative complications of lung cancer as failure of Qi to ascend and descend leading to insecurity of defensive exterior， vessel block leading to Qi stagnation and fluid retention， and lung Qi deficiency leading to spleen and kidney deficiency. Accordingly， this paper proposes the treatment principle of protecting healthy Qi and treating Qi with the core of descending-tonifying-ascending-dispersing Qi and puts forward three treatment methods. The first is replenishing Qi and consolidating exterior， and expelling phlegm and regulating lung. The second is replenishing Qi and promoting blood flow to resolve stasis and relieving pain. The third is replenishing Qi and tonifying lung， and invigorating spleen and tonifying kidney. Furthermore， this paper elaborates on the pathogenesis and treatment principles of four common postoperative complications： Lung infection， pleural effusion， atelectasis， and bronchopleural fistula. On the basis of Western medical treatment， the TCM treatment characteristics of treating symptoms in the acute phase and eradicating the root cause in the chronic phase should be played. While dispelling the pathogen， measures should be taken to protect the healthy Qi， including tonifying lung Qi， regulating spleen Qi， and replenishing kidney Qi. This study summarizes the pathogenesis and treatment strategy of common postoperative complications of lung cancer according to the principle of protecting healthy Qi and treating Qi， aiming to provide guidance for the future treatment of postoperative complications of lung cancer.

Objective:Assessing the therapeutic efficacy of methotrexate(MTX)-modified magnetic nanoparticles in thermo-chemotherapy for rat breast cancer and its impact on immune function.Methods:Female Wistar rats were subcutaneously inoculated with breast cancer Walker-256 cells to establish a transplantation tumor model,and injected with polyethyleneimine(PEI)-modified Fe3O4 magnetic nanoparticles(47T group,42T group and multiple 42T group)or MTX-modified Fe3O4 magnetic nanoparticles(47TC group,42TC group and multiple 42TC group)for thermotherapy under the magnetic field at different temperatures(47℃and 42℃).The rats injected with MTX-modified magnetic fluid only(MFC group)and the tumor-bearing rats without any treatment(blank control group),with irradiation treatment in an alternating magnetic field only for 30 minutes(M group),with injection of PEI-modified magnetic fluid only(MF group),with treatment of MTX-mono drug(MTX group)and not inoculated with tumor cells(normal group)were used as control groups.X-ray radiography was used to display the distribution of magnetic fluid in the tumor tissue 24 hours,2 weeks and 2 months after intra-tumor injection.After 24 hours of treatment,three rats were selected from each of the 47T and 47TC groups,and the effect of magnetic fluid on tumor cells was observed under an electron microscope after execution.After 14 days of treatment,the tumor volume of rats was measured and statistically analyzed.At the same time,4 rats were selected from each of the 47TC,47T,42TC,42T,MFC,MTX,blank control and normal groups,and the levels of IL-2,IFN-γ and IL-4 in peripheral blood were detected by ELISA method.The remaining rats were observed for long-term survival.Results:The magnetic nanoparticles were evenly distributed in the center of the tumor but unevenly distributed at the tumor's edge;they primarily localize amomg tumor cells and can penertrate into tumor cells.Tumor growth was inhibited in rats in the 47TC,47T,multiple 42TC and multiple 42T groups(all P<0.05),and the survival rates of the rats were high.As compared with the blank control group,the levels of IL-2 and IFN-γ were increased while the IL-4 level was decreased in the 47TC and 47T groups(all P<0.05).Conclusion:Thermo-chemotherapy at 47℃for 30 minutes and multiple sessions at 42℃for 60 minutes can partially inhibit tumor growth and prolong rat survival.This effect maybe related to the thermo-chemotherapy at 47℃for 30 minutes which can activate the body's immune function.

Objective:To explore the clinical features and genetic etiology of a child with a SETD1B gene variant causing seizures and language delay. Methods:A child with a SETD1B gene variant admitted to the Department of Pediatric Neurology at the Third Affiliated Hospital of Zhengzhou University in September 2022 was selected as the study subject. Clinical data of the child were collected, and peripheral blood samples from the child and her parents were obtained. Whole exome sequencing (WES) was performed for genetic testing, and Sanger sequencing was used for familial validation of the candidate variant. Using " SETD1B" and " epilepsy" as the Chinese and English keywords, relevant cases were retrieved from databases including CNKI, Wanfang Data, OMIM and PubMed, with the search period spanning from database inception to June 2024. Results:① The child was a 6-year-old female presenting with myoclonic seizures accompanied by global developmental delay. ② WES and Sanger sequencing revealed that the child has carried a de novo SETD1B gene variant, namely, c. 5582G>A (p.Cys1961Tyr). According to the American College of Medical Genetics and Genomics (ACMG) guidelines for sequence variant interpretation, this variant was classified as likely pathogenic (PS2+ PM2_Supporting+ PP2+ PP3). ③ The child was not controlled with effective doses of valproate, levetiracetam, or clonazepam but was successfully managed with low-dose lamotrigine. Follow-up electroencephalography showed normal results, and developmental progress gradually improved. ④ A total of 37 epilepsy cases with SETD1B gene variants were reported across six studies. The predominant seizure types included absence seizures and myoclonic absence seizures, accompanied by delayed language development. The response to pharmacological treatment was generally poor, with no statistically significant difference in incidence between males and females. Conclusion:SETD1B gene variant may induced neurological disorders with drug-resistant epilepsy and severe clinical manifestations. Lamotrigine is effective in controlling the epileptic seizures.
