ObjectiveTo investigate the characteristics and distribution of traditional Chinese medicine （TCM） syndromes in the patients with esophageal squamous cell carcinoma （ESCC）. MethodsAn electronic questionnaire was developed to collect the general data and four examination information of ESCC patients treated in 10 areas with high incidence of esophageal cancer in China from June 2020 to March 2021. Multiple analyses including frequency analysis， factor analysis， and hierarchical cluster analysis were performed to analyze the potential syndrome elements， disease location， and common syndromes of ESCC. ResultsA total of 2 027 patients with ESCC were included. Statistical analysis was performed on 113 symptoms， physical signs， 33 tongue manifestation variables， and 23 pulse manifestation variables of the patients’ four examination information. Factor analysis was performed on 55 variables with frequency>10%， extracting 19 common factors. According to clinical experience and expert opinions， the main lesions of patients with ESCC were in the spleen and stomach， and the main syndrome elements were Qi stagnation， blood stasis， phlegm， dampness， and Qi deficiency， with the syndrome element combination of phlegm obstruction + Qi stagnation + blood stasis being the most common. The syndromes can be classified into four categories of liver-stomach disharmony + combined phlegm and Qi obstruction， kidney-spleen dysfunction + combined phlegm and stasis， spleen-kidney Yang deficiency + obstinate phlegm and blood stasis， and liver-kidney Yin deficiency + obstinate phlegm and blood stasis. The main syndrome of ESCC was liver-stomach disharmony + combined phlegm and Qi obstruction in the early stage， liver-spleen dysfunction + combined phlegm and stasis in the middle stage， and spleen-kidney Yang deficiency + obstinate phlegm and blood stasis in the late stage. ConclusionESCC mainly has main pathological features of internal deficiency and external excess and combined deficiency and excess， with the key syndrome elements being phlegm obstruction， Qi stagnation， and blood stasis. The main disease locations are in the spleen and stomach， involving the liver， kidney， chest and diaphragm， heart， and lung. The main syndrome is liver-stomach disharmony + combined phlegm and Qi obstruction. In clinical practice， it is necessary to grasp the pathogenesis dynamics of the disease and use prescriptions according to patients’ syndromes.

Objective To investigate the application effects of cardiac resynchronization therapy(CRT)of[left bundle optimization(LOT)]and biventricular pacing(BiV)in the patients with chronic heart failure complicating left bundle branch block.Methods The single center,prospective and non-randomized controlled study method was used.Forty-two patients with heart failure meeting CRT in this center from April 2020 to April 2022 were consecutively included.Among them,32 cases adopted the BiV-CRT(BiV-CRT group)and 10 cases adopted LOT-CRT(LOT-CRT group).The pacing-making parameters,quality of life scale(SF-36)score,6-min walk test(6-MWT),ECG QRS width(QRSd),left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF)and New York cardiac function grade(NYHA)situation were collected before surgery,after surgery immediately and in postoperative 3,6,12 months.Their complica-tions and clinical outcomes were evaluated.Results The pacing threshold value in the LOT-CRT group was stable and lower than that in the BiV-CRT group(P＜0.05);QRSd in postoperative 12 months in the LOT-CRT group was shorter than that in the BiV-CRT group[(115.0±14.3)ms vs.(133.0±14.0)ms,P＜0.05]and 6-MWT was longer than that in the BiV-CRT group[(327.0±52.8)m vs.(274.0±52.8)m,P＜0.05],and the differences were statistically significant(P＜0.05);LVEF,LVEDD,NYHA cardiac grade and SF-36 score in postoperative 12 months were improved compared with those before implantation.The rehospitaliza-tion rate of heart failure in the LOT-CRT group was lower.Conclusion LOT-CRT could obtain a narrower QRS wave and longer 6-MWT than BiV-CRT.

Objective To describe the incidence and mortality of brain tumors in China in 2020 and to predict the disease burden up to 2040.Methods The brain tumor incidence and mortality in 2020 were recorded based on the data from International Agency for Cancer Research(IARC),Cancer Today database.The incidence and mortality were standardized by age using Segi's world standard population.The burden of brain tumors in 2040 was predicted with assuming that national rates remained constant in 2020.Results It was estimated there were approximately 79 600 new brain tumors cases and 65 200 deaths in China in 2020.The age-standardized incidence and mortality rates of brain tumors in China were 4.1/100 000 and 3.2/100 000,respectively,which were lower than the United States of America,most of European countries and Australia.The incidence and mortality were higher than Africa,central America,and the Caribbean.From 2020 to 2040,the brain tumors cases and deaths are predicted to have an increase as 32.1%and 41.5%respectively.Conclusions The disease burden of brain tumors was still heavy in China.Further studies are urgently needed to clarify the epidemic trend of tissue typing and risk factors of brain tumors,which may support the development of effective prevention strategies.

BACKGROUND:Tissue engineering is considered an ideal treatment for growth plate regeneration.However,most of the current research on regenerative tissue engineering is the traditional scaffold-based strategy.As the limitations of traditional scaffolds are gradually revealed,the research direction is gradually diversifying. OBJECTIVE:To summarize the application of scaffold-based and scaffold-free strategies in the treatment of growth plate cartilage regeneration and their respective advantages and disadvantages. METHODS:The relevant articles were searched from PubMed,Wiley,and Elsevier.The search terms were"growth plate injury,regeneration,tissue engineering,scaffold,scaffold-free,biomimetic,cartilage"in English.The time was limited from 1990 to 2023.Finally,104 articles were included for review. RESULTS AND CONCLUSION:The biomimetic strategy is to reduce the cell composition,biological signals and unique mechanical properties of each region to the greatest extent by simulating the unique organizational structure of the growth plate,so as to build a biomimetic microenvironment that can promote tissue regeneration.Therefore,the design of a biomimetic scaffold is to simulate the original growth plate as far as possible in terms of composition,structure and mechanical properties.Although some results have been achieved,there is still the problem of the unstable regeneration effect.The scaffold-free strategy believes that the limitations of scaffolds will have adverse effects on regenerative therapy.Therefore,the design of scaffold-free constructs relies as much as possible on the ability of cells to generate and maintain extracellular matrix without interfering with cell-cell signals or introducing exogenous substances.However,there are some problems,such as poor stability,low mechanical strength and greater difficulty in operation.Biomimetic strategy and scaffold-free strategy have different emphases,advantages and disadvantages,but they both have positive effects on growth plate cartilage regeneration.Therefore,subsequent studies,whether adopting a biomimetic strategy or a scaffold-free strategy,will focus on the continuous optimization of existing technologies in order to achieve effective growth plate cartilage regeneration therapy.

Ferroptosis is an iron-dependent form of regulated cell death,which is distinct from apoptosis,ne-crosis,and pyroptosis.Recent studies have found that activators of ferroptosis,such as Erastin,can activate autophagy-re-lated proteins,induce the formation of autophagosomes,and ultimately release ferric ions to mediate ferroptosis.This pro-cess,called ferritinophagy,is initiated by the binding of an autophagic cargo receptor protein,nuclear receptor coactivator 4(NCOA4),to iron-laden ferritin.The transfer of NCOA4-ferritin to the lysosome by ferritinophagy results in the proteoly-sis of ferritin,and,in turn,the release of its iron content and lipid-reactive oxygen species(ROS)accumulation.Ferritin-ophagy has been closely associated with central nervous system disorders,circulatory system diseases,and cancer.Fur-thermore,the regulation mechanism of ferritinophagy is also a hot topic in the study of iron-dependent cell death process.With the in-depth study of ferritinophagy,great progress has been made in the study of key components of ferritinophagy as well as its molecular mechanisms and processes.However,a comprehensive summary of the methods for detecting ferritin-ophagy is still unclear.To further deepen the understanding of ferritinophagy and its detection methods,this review focus-es on the concept,characteristics,methods,and precautions during detection of ferritinophagy.This review provided ex-perimental reference for subsequent researchers and promoting the progress of research related to ferritinophagy.

Objective:To explore the correlations of neurological function recovery and intraoperative bone window parameters with intracranial pressure (ICP) changes at perioperative period in patients with large hemispheric infarction (LHI) after standard large bone flap decompression.Methods:Forty LHI patients accepted standard large bone flap decompression in Department of Neurosurgery, People's Hospital of Zhengzhou University from December 2020 to December 2023 were enrolled. ICP was measured before decompression, at the time of bone flap removal, during dural opening, and 24 h after decompression. Correlations of National Institutes of Health Stroke Scale (NIHSS), Extended Glasgow Outcome Scale (GOSE) and Glasgow Coma Scale (GCS) score changes, length and area of the bone window, bone window area/cranial bone area, infarct brain tissue volume/brain tissue volume with ICP changes were analyzed by Pearson's correlation. Length and area of bone window in patients with good neurological function recovery (NIHSS score decreased by≥5, GOSE score increased by≥3, or GCS score increased by≥3 before and after decompression) were calculated.Results:ICP at the time of bone flap removal, during dural opening, and 24 h after decompression was significantly lower than that before decompression ( P<0.05); ICP at the time of bone flap removal was higher than that at 24 h after decompression and during dural opening. Reduction between ICP before decompression and that during dural opening was more obvious than ICP reduction before and 24 h after decompression and ICP reduction before decompression and at the time of bone flap removal, with significant differences ( P<0.05). Postoperative NIHSS scores were significantly lower than preoperative ones ( P<0.05), and both postoperative GOSE and GCS scores were significantly higher than preoperative ones ( P<0.05). Decrease of NIHSS score, increase of GOSE and GCS scores before and after decompression were positively correlated with ICP reduction before and 24 h after decompression ( r=0.386, P=0.018; r=0.411, P=0.033; r=0.319, P=0.037); length and area of the bone window were positively correlated with ICP reduction before and 24 h after decompression ( r=0.461, P=0.028; r=0.536, P=0.034); bone window area/cranial bone area was positively correlated with ICP reduction before and 24 h after decompression ( r=0.438, P=0.027), while infarct brain tissue volume/brain tissue volume was negatively correlated with ICP reduction before and 24 h after decompression ( r=-0.371, P=0.031). Of the 40 patients, 25 had good neurological function recovery after decompression, with length of the bone window ranged 12.3-16.7 cm and area of the bone window ranged 54.5-91.9 cm 2. Conclusion:Standard large bone flap decompression can reduce ICP and improve prognosis in LHI patients; intraoperative bone window parameters are obviously correlated with ICP reduction before and 24 h after decompression; length of the bone window ranged 12.3-16.7 cm and area of the bone window ranged 54.5-91.9 cm 2 are suggested for decompression.

Glioma is the most common type of cancer in the brain and central nervous system,mainly originated from glioma cells or neuronal cells.It is characterized by high prevalence,recurrence rate and mortality.Among aggressive brain tumors,the incidence of glioma is the highest.Long non-coding RNA(lncRNA)is one of the most popular non-coding RNAs in tumor research.It has a variety of biological functions and regulates gene expression at the transcription,post-transcription and genetic levels.It was found that lncRNA was abnormally expressed in cancer patients,and abnormally expressed lncRNA was also found in glioma.lncRNA regulates the occurrence and development of gliomas through different signaling pathways,and affects the heterogeneity and invasiveness of gliomas through the glycolytic pathway.In addition,immune-related lncRNAs are valuable in evaluating the diagnosis,treatment and prognosis of gliomas.In this article,the role of lncRNA in glioma will be reviewed from three aspects including regulation of signaling pathway,glycolytic pathway and immunoregulation.

Objective:To investigate the application of diagnostic criteria for common occupational radiation-induced diseases to radiation workers, in order to provide a basis for the revision, publicity and standardization of the standards.Methods:Radiation workers were selected from 1 city, 7 provinces and 1 corporation by using cluster random sampling method from January 2021 to May 2021. Awareness of the criteria and the effects of ionizing radiation, and the suggestions for diagnostic works were investigated and analyzed.Results:A total of 2 839 radiation workers were investigated. There were differences in the awareness of different diagnostic criteria, the inclusions in complex diagnostic criteria, the materials required for applying for diagnosis, and the ways of knowing the diagnostic criteria( χ2=416.06, 2 924.14, 83.45, 895.67, 815.94, P<0.001). The correct understanding rates of deterministic effects and stochastic effects were 80.63% and 43.64%, respectively. The acceptance rates in applicable materials were 96.79% for occupational exposure history, 94.72% for occupational health monitoring records and 93.55% for individual monitoring of occupational exposure, respectively. Pre-employment training rate was 80.20%, on-job training rate was 81.19%, and untrained rate was 3.77%. The suggestions to the diagnosis of occupational radiation-induced diseases are to strengthen training, pay attention to individual monitoring, occupational health examination, and strengthen health supervision and law enforcement. Conclusions:Radiation workers have a low awareness rate of certain diagnostic standards and a high awareness rate of diagnostic procedures. Publicity and training of health effects of ionizing radiation and diagnostic criteria of occupational radiation-induced diseases should be strengthened. Diagnostic procedure should be optimized.
