RESUMO
Background: The tuna industry is one of the most essential sectors in global food production. Nevertheless, commercial meat known as "tuna loin" holds the utmost significance in producing and marketing its various products. Regrettably, fractions like tail and head meat have been overlooked and wasted due to their comparatively lower commercial value. Despite possessing notable technological value, this meat is typically reutilized into animal feed through flour production, missing the chance to create alternative high-value food products. Objective: This study aimed to develop and evaluate the sausages produced with the underutilized cuts of tuna (tail and head meat). Methods: The tuna utilized were Big-eye (Thunus obesus) and Skip-jack (Katsuwonus pelamis lineaus). Three (3) different types of sausages were formulated using 100% of Big-eye (BE), 100% of Skip-jack (SJ) tuna meat, and 100% of beef/pork meat (Control). The sausage pH changes during storage at 4 ± 1oC were analyzed and compared with the control. Proximal, microbiological, and sensory characteristics were evaluated. Results: The pH of sausages showed that the values tended to decrease in control, while this value increased in two types of tuna. The formulated tuna sausages yielded 72% moisture, 18% protein, 4.1% lipid, 0.4% ash, 0.4 % fiber, and 4.5% carbohydrates. Sensory attributes showed excellent acceptance regarding color, smell, flavor, and texture. Overall acceptability was qualified as "liked," and the acceptability index ranged from 76% to 86%. During the refrigeration storage, the microbiological analyses indicated that the total coliform count was < 3 CFU/g. Escherichia coli, Staphylococcus aureus, and mesophilic aerobic bacteria in tuna sausage showed absence during 24 days of storage. Conclusion: Using tuna tail and head meat enabled the development of gel-type emulsified products (sausages) that exhibited good nutritional, sensory, and microbiological quality
Antecedentes: La industria atunera se erige como uno de los sectores más importantes en la producción mundial de alimentos. Sin embargo, entre sus diversos productos, la carne comercial conocida como "lomo de atún" ostenta la mayor importancia tanto en su producción como en su comercialización. Lamentablemente, fracciones de carne provenientes de la cola y la cabeza se han desperdiciado debido a su reducido valor comercial. A pesar de poseer un notable valor tecnológico, esta carne normalmente es utilizada en la alimentación animal mediante la producción de harina, perdiendo la oportunidad de desarrollar productos alimenticios alternativos con alto valor nutricional. Objetivo: Este estudio tuvo como objetivo desarrollar y evaluar salchichas producidas con carne subutilizada de atún (carne de cola y cabeza). Métodos: Las especies de atún utilizadas fueron Big-eye (Thunus obesus) and Skip-jack (Katsuwonus pelamis lineaus). Se formularon tres (3) tipos diferentes de salchichas usando 100 % de carne de atún Big-eye (BE), 100 % de Skip-jack (SJ) y 100 % de carne de res/cerdo (Control). Se analizaron los cambios de pH en las salchichas durante el almacenamiento a 4 ± 1 oC y se compararon con el Control. También se evaluaron la composición proximal, calidad microbiológica y atributos sensoriales. Resultados: El pH mostró que los valores tendieron a disminuir en relación a la muestra Control, mientras que este valor aumentó en los dos tipos de salchicha con carne de atún. Las salchichas con carne de atún mostraron un 72 % de humedad, 18 % de proteína, 4,1 % de lípidos, 0,4 % de ceniza, 0,4 % de fibra, 4,5 % de carbohidratos. Los atributos sensoriales mostraron buena aceptabilidad de los parámetros de color, olor, sabor y textura. La aceptabilidad general se calificó como "me gusta" y el índice de aceptabilidad osciló entre el 76 % y el 86 %. Durante el periodo de almacenamiento en refrigeración, los análisis microbiológicos indicaron que el recuento de coliformes totales fue < 3 UFC/g. No se evidenció la presencia de Escherichia coli, Staphylococcus aureus y bacterias aerobias mesófilas durante 24 días de almacenamiento. Conclusión: El aprovechamiento de la carne de la cola y cabeza del atún permitió desarrollar productos emulsionados tipo gel (embutidos) que exhibieron buena calidad nutricional, sensorial y microbiológica.

Abstract The use of alternative nutritional sources is an important topic for animal production such as poultry. This study examined the effect of replacing soybean meal with sunflower leaf meal in the diet of laying shaver brown pullets. A total of 30 laying birds were assigned to three treatments of 0% (as control group), 10% and 15% MSFLM inclusion. Four eggs per replicate were randomly taken for three consecutive days at two weeks interval for five times, and 18 weeks individuals were selected after 40 days of experimental time. External parameters of the eggs (egg weight, egg length, egg breadth and egg shape index, shell thickness), and body parameters (Final body weight, weight gain), feed intake and hen day production were measured. For egg length, egg breadth and shell thickness showed significant difference (p 0.05) in from the control birds. Final body weight, weight gain, feed intake and hen day production showed comparable results with values from eggs of birds on control diet. The study revealed the ability of birds to easily utilize the nutrients in the protein sources. MSFLM utilization up to 15% in pullets diet revealed no detrimental effect on the performance of the laying birds and the external qualities of eggs produced.
Resumo O uso de fontes nutricionais alternativas é um tópico importante para a produção animal, como a avicultura. Este estudo examinou o efeito da substituição do farelo de soja por farelo de folha de girassol na dieta de frangas marrons barbeadoras poedeiras. Um total de 30 aves poedeiras foram designadas a três tratamentos de 0% (como grupo controle), 10% e 15% de inclusão MSFLM. Quatro ovos por repetição foram retirados aleatoriamente por três dias consecutivos em intervalos de duas semanas por cinco vezes, e indivíduos de 18 semanas foram selecionados após 40 dias do tempo experimental. Parâmetros externos dos ovos (peso do ovo, comprimento do ovo, largura do ovo e índice de forma do ovo, espessura da casca) e parâmetros corporais (peso corporal final, ganho de peso), consumo de ração e produção diária da galinha foram medidos. Para comprimento do ovo, largura do ovo e espessura da casca apresentaram diferença significativa (p 0,05) nas aves controle. Peso corporal final, ganho de peso, consumo de ração e produção de dia de galinha mostraram resultados comparáveis com valores de ovos de aves em dieta controle. O estudo revelou a capacidade das aves de utilizar facilmente os nutrientes das fontes de proteína. A utilização de MSFLM até 15% na dieta das frangas não revelou nenhum efeito prejudicial no desempenho das aves poedeiras e nas qualidades externas dos ovos produzidos.

RESUMO
ObjectivesTo analyze the spatial and temporal clustering characteristics and related influencing factors of late diagnosis of HIV/AIDS in Lanzhou， to identify its high-risk areas and time trends in Lanzhou， and to provide a theoretical basis for developing targeted HIV/AIDS prevention and control strategies in Lanzhou. MethodsThe subjects of this study were adult HIV/AIDS cases reported in Lanzhou City between 2011 and 2018. Data used in the study were sourced from the Lanzhou Center for Disease Control and Prevention and the Lanzhou Statistical Yearbook. To analyze the spatial distribution characteristics and influencing factors of the relative risk （RR） of late HIV/AIDS diagnosis， Bayes spatial-temporal model was used. ResultsA total of 1984 new HIV/AIDS cases were reported in Lanzhou from 2011 to 2018， with an mean age of 37.51 years and predominantly male （91.8%）. The number of late diagnosis cases was 982， with an mean age of 39.67 years and a predominance of males （91.8%）. Late diagnosis was more common in older individuals and women with HIV/AIDS. Chengguan District （51.1%）， Anning District （50.3%） and Yuzhong County （51.9%） had an above-average proportion of late diagnosis of HIV/AIDS. The proportion of late diagnosis cases in Lanzhou showed a fluctuating upward trend from 2011 to 2018. The results of Bayes spatial-temporal model showed that the risk of late HIV/AIDS diagnosis in Lanzhou had fluctuated from 2011 to 2015， and then increased rapidly after 2015 ［RR （95% credibility interval， 95%CI） increased from 1.01 （0.84， 1.23） to 1.11 （0.77， 1.97）］； the trends of risk of late diagnosis in Honggu district and three counties were similar to the overall trend in Lanzhou city， while the risk of late diagnosis in Chengguan District and Qilihe District showed a decreasing trend. The regions with the RR for late diagnosis greater than 1 included Yongdeng County （RR=1.07， 95% CI： 0.55， 1.96）， Xigu District （RR=1.04， 95% CI： 0.67， 1.49）， Chengguan District （RR=2.41， 95% CI： 0.85， 6.16）， and Qilihe District （RR=2.03， 95% CI： 1.10， 3.27）. Besides， the heatmap analysis showed that Chengguan District and Qilihe District were the hot spots. The influencing factors analysis showed that the higher GDP per capita （RR=0.65， 95% CI： 0.35， 0.90） and the larger proportion of males with HIV/AIDS cases （RR=0.53， 95% CI： 0.19， 0.92） could lead to the lower the relative risk of late HIV/AIDS diagnosis. However， the higher the population density （RR=1.35， 95% CI： 1.01， 1.81） caused the higher the risk of late diagnosis. ConclusionOur study shows the risk of late diagnosis of HIV/AIDS in Lanzhou was on the rise， and there are significant regional differences. GDP per capita， the proportion of males in HIV/AIDS cases and population density are influencing factors in the late diagnosis of HIV/AIDS. Therefore， for regions with a high risk of late diagnosis or related risk factors， targeted HIV screening and prevention services should be given priority in order to reduce the proportion and risk of late diagnosis of HIV/AIDS.
RESUMO
Objective To explore the correlation between clinical distribution characteristics of streptococcal pharyngitis in children and seasonal variations in Ziyang area, so as to provide basis for disease prevention and control. Methods A multistage and stratified random sampling technique was used to investigate 583 children with streptococcal pharyngitis attending Ziyang first people's Hospital from January 2022 to January 2023. The clinical data were recorded. The pharyngeal specimens were cultured for streptococci test. The number of streptococcal pharyngitis cases per season was counted. The metereological conditions (average barometric pressure, temperature, rainfall, and wind speed) were recorded. Pearson method was used to discuss the correlation between metereological factors and streptococcal pharyngitis onset. Results A total of the 583 children, 329 were male and 254 were female. The main age of onset was 7-12 years old, with a total of 227 cases (38.94%), followed by 199 cases (34.13%) aged 3-6 years old, 126 cases (21.61%) aged 1-2 years old, and 31 cases (5.32%) under 1 year old. A total of 614 strains of pathogenic bacteria were detected, of which 479 strains of Streptococcus hemolyticus were dominant, accounting for 78.01%, followed by 175 strains of Streptococcus pyogenes, accounting for 28.50%. Seasonally, 192 cases of streptococcal pharyngitis occurred in spring, 51 in summer, 72 in autumn and 268 in winter. In Ziyang, spring and winter were characterized by high mean wind speeds and barometric pressure, while summer and autumn were characterized by high mean temperatures and heavy rainfall. Pearson correlation analysis revealed that the prevalence rate streptococcal pharyngitis was positively correlated with average wind speed and barometric pressure (P<0.05), and negatively correlated with mean temperature and rainfall (P<0.05). Conclusion In Ziyang, streptococcal pharyngitis occurs mostly in children over 5 years old, and the main pathogen is Streptococcus hemolyticus. The onset of the disease is mostly in spring and winter, which is closely related to the seasonal variations of the region.
RESUMO
Objective To understand the epidemiological characteristics and current situation of pertussis in Hubei Province from 2016 to 2021. Methods Data on the incidence of pertussis and immunization history of cases in Hubei Province from 2016 to 2021 were collected and descriptive epidemiological analysis was conducted. Results From 2016 to 2021, a total of 1 236 pertussis cases were reported in Hubei Province, with an average annual reported incidence rate of 0.35/100 000. The average annual reported incidence of pertussis in the age group ≤ 5 years old was 6.22/100 000, and the age group <1 year old reported the highest annual incidence rate (21.51/100 000). The proportion of pertussis among preschool children and students had increased significantly since 2020. Among the 1 111 cases with a known immunization history, 17.55% were under the age of vaccination , 41.85% were not vaccinated, and 17.46% had completed the whole course of vaccination. Conclusion Since 2016, the incidence of pertussis in Hubei Province has been on the rise. The risk of pertussis is higher in infants and young children who have not reached the age of vaccination and who have not been vaccinated in time according to the immunization program after reaching the age of vaccination. The timeliness and vaccination rate of DTP vaccine should be improved to reduce the risk of pertussis in infants and young children. In addition, more attention should be paid to the prevalence of pertussis among preschool children and students.

RESUMO
@#Objective To investigate the etiology, symptoms, diagnosis, surgical treatment, and outcomes of acute necrotizing mediastinitis (ANM) in order to guide future diagnosis and treatment of ANM. Methods The clinical data of patients with ANM referred to West China Hospital, Sichuan University from March 2012 to April 2021 were retrospectively analyzed. The etiology, clinical manifestations, demographic characteristics, bacterial culture results, surgical approach and prognostic factors of these patients were summarized. Results A total of 176 patients were enrolled in this study. The median age was 60 ( 0-84) years. There were 124 (70.5%) males and 52 (29.5%) females. The most common origin of infection was neck (n=66, 37.5%). The most common symptom was fever (n=85, 48.3%). Streptococcus constellatus represented the most common pathogens in secretion culture. Surgical treatment was administered to 119 (67.6%) patients through different approaches, including 54 (30.7%) patients of cervical approach, 9 (5.1%) patients of thoracotomy, 18 (10.2%) patients of video-assisted thoracoscopic surgery (VATS), 7 (4.0%) patients of cervical combined with thoracotomy, 30 (17.0%) patients of cervical combined with VATS, and 1 (0.6%) patient of subxiphoid approach. Among this cohort, 144 (81.8%) patients were cured, while 32 (18.1%) patients died. Age-adjusted Charlson comorbidity index (OR=2.95, P=0.022), perioperative sepsis (OR=2.84, P=0.024), and non-surgical treatment (OR=2.41, P=0.043) were identified as independent predictors of poor outcomes. Conclusion For patients with corresponding history and manifestations of ANM, it is crucial to go through imaging examination to confirm the presence of an abscess and guide the selection of surgical approach. Once the diagnosis of ANM is made, it is imperative to promptly perform surgical intervention for effective drainage. Our study highlights the significance of age-adjusted Charlson comorbidity index, perioperative sepsis and surgical treatment in predicting patients’ outcomes.

RESUMO
ObjectiveBased on the new method of animal model evaluation， this paper summarized and analyzed the characteristics of traditional Chinese medicine（TCM） and Western medicine syndromes in existing autism spectrum disorder（ASD） animal models， and put forward suggestions for improvement. MethodRelevant literature on ASD animal models in China National Knowledge Infrastructure（CNKI） and PubMed were searched. According to the diagnostic standards of traditional Chinese and western medicine， core symptoms and accompanying symptoms were assigned values， and the clinical consistency of the models was comprehensively evaluated. ResultMost ASD model experimental animals were rodents， and the modeling methods included genetic and non-genetic. Domestic research focused on biochemical induction， while foreign research used genetic models more commonly. Among all models， valproic acid induction had the highest clinical consistency， followed by the neuroligin 4（NLGN4） and contactin associated protein like 2（CNTNAP2） gene knockout models. Most modeling methods could meet the characteristics of surface validity and structural validity， but did not clearly distinguish TCM syndromes. Currently， there is no model that has a high degree of clinical agreement between TCM and western medicine at the same time. ConclusionThe existing ASD animal models are mostly constructed under the guidance of western medicine， which lacks the characteristics of TCM syndromes. And the selection of evaluation indicators of western medicine is relatively single， without specifying the types of TCM syndromes. It is recommended to apply TCM intervention factors during the process of model preparation， to improve the evaluation indicators of traditional Chinese and western medicine， and to emphasize the study of on non-human primates， so as to lay a solid foundation for future experiments.
RESUMO
Due to the difference of cultural background, the psychological, social and spiritual needs of dying people are very different, so there are great differences in the care and nursing concept of dying people in different countries and nationalities. In order to construct the modern hospice care, we should actively learn from the western experience, but more important is to dig the local ideological resources from the traditional culture, build a set of caring care theory and practice rooted in China and originated from the concept of a good end of Chinese traditional culture, with the characteristics of the times and the cultural confidence of the Chinese nation, serving the Chinese people, and with Chinese characteristics.
RESUMO
ObjectiveOvarian cancer is the third most common gynecologic cancer worldwide， with the second highest mortality rate among gynecologic cancers， and age-standardized rates are gradually increasing in many low- and middle-income countries. At present， its etiology and pathogenesis are not clear. There are no obvious symptoms in the early stage， and when the symptoms become obvious， it often indicates the advanced stage. The 5-year survival rate of the advanced stage is only 17%， which poses a great threat to women's health. Therefore， an in-depth study of the etiology and pathogenesis of ovarian cancer is very important to the exploration of prevention and treatment methods for ovarian cancer. Based on the clinical characteristics of ovarian cancer in traditional Chinese and Western medicine， and combined with the existing evaluation methods of animal models， this study evaluated the animal model of ovarian cancer， and provided analysis and suggestions. MethodThis study searched China National Knowledge Infrastructure （CNKI）， Wanfang data， VIP information database， and PubMed database using the keywords "ovarian cancer" and "animal model"， excluded the articles that did not meet the criteria， and then classified the remaining studies. Combined with the clinical diagnostic criteria of Western medicine and traditional Chinese medicine syndrome differentiation， the related indicators of ovarian cancer animal models were assigned and the degree of agreement was evaluated. ResultThe use of the transplanted animal model exhibited the highest frequency， followed by that of the induced model. The degree of agreement of traditional Chinese medicine for each model was lower than that of Western medicine. The induced ovarian cancer model had a high degree of clinical agreement and was similar to human ovarian cancer in terms of tumor growth pattern， disease progression and complications， which is an ideal animal model of ovarian cancer. Although this animal model can simulate the etiology and pathogenesis of ovarian cancer to a certain extent and reflect some indicators of traditional Chinese and Western medicine， it lacks differentiation of traditional Chinese medicine syndromes. ConclusionOn the basis of the original model， the animal model of ovarian cancer was added with Qi deficiency syndrome， blood deficiency syndrome， Qi stagnation syndrome， blood stasis syndrome， heat-toxin syndrome， and Yang deficiency syndrome to establish an animal model combining traditional Chinese medicine disease and syndrome of ovarian cancer， which could better simulate the clinical actual situation of traditional Chinese and Western medicine and lay a solid foundation for the study of integrated traditional Chinese and Western medicine for the treatment of ovarian cancer.
RESUMO
BackgroundWomen may develop severe symptoms of stress disorder following childbirth， which may be exposed to a risk of developing mental health problems， and even lead to the recurrence of the illness in female patients with schizophrenia， while comparatively limited research has been undertaken concerning the clinical characteristics and treatment of puerperal schizophrenia in China. ObjectiveTo explore the clinical characteristics of puerperal schizophrenia， so as to provide references for the clinical treatment. MethodsA total of 24 patients with puerperal schizophrenia who were hospitalized in the female ward of adult psychiatry department of the Affiliated Brain Hospital of Guangzhou Medical University from 2012 to 2020 and met the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） diagnostic criteria for schizophrenia were included as puerperal group. Another 48 non-puerperal women with schizophrenia were concurrently enrolled as control group. Then the basic data， scores on Positive and Negative Symptom Scale （PANSS） and the discharge medication were recorded. ResultsThe percentages of newly onset and positive family history of psychosis in puerperal group were larger than those in control group， with statistical significance （χ2=9.321， 5.240， P<0.05 or 0.01）. Puerperal group scored higher on PANSS excitement factor （t=-2.220， P<0.05） and lower on negative factor （t=3.377， P<0.01） compared with control group. In terms of discharge medication， puerperal group reported a higher dosage of antipsychotic drugs （t=-2.095， P<0.05）， and a larger proportion of combined use of benzodiazepines or antidepressants （χ²=21.316， 5.114， P<0.05 or 0.01） compared with control group， with statistical significance. ConclusionPatients with puerperal schizophrenia display increased ratings of excitement symptoms and decreased ratings of negative symptoms， which necessitates the use of high doses of antipsychotic drugs， and combined use of benzodiazepines and antidepressants.
RESUMO
@#Objective To isolate and identify Lactobacillus paracasei and Bacillus subtilis from feces of northern white geese.Methods Lactobacillus paracasei and Bacillus subtilis,numbered S00834-8 and IS00439-2 respectively,were isolated from feces of 30 52-week-old northern white geese and cultured in specific medium,and identified by 16S DNA sequencing. The two strains were cultured for different time duration(0,2,4,6,8,10,12,14,16,18,20,22,24,36 and 48 h),at different temperature(34,36,37,38 and 40 ℃)and pH(5. 5,6. 0,6. 5,7. 0,7. 5 and 8. 0). The growth characteristics of the strains were evaluated according to the A600values measured by UV-Vis spectrophotometer. At the same time,the acid and bile salt tolerance(pH 2. 0,2. 5,3. 0,3. 5 and 7. 0,bile salt concentration 0,0. 3%,0. 5%,1. 0% and 1. 5%)and the antibiotic tolerance were tested. Results The strains S00834-8 and IS00439-2 were Lactobacillus paracasei subspecies tolerance H and Bacillus subtilis KA9,respectively. The strain S00834-8 cultured under the optimum condition of the culture medium with pH 6. 0,at 37 ℃,for 12 h,had good bile resistance and gastric acid resistance,which was moderately susceptible to piperacillin,norfloxacin,amikacin,gentamicin and tetracycline,and susceptible to levofloxacin,streptomycin and chloramphenicol. The strain IS00439-2 best cultured in the culture medium with pH 7. 5,at 36 ℃,for 8 h,showed good bile resistance and gastric acid resistance,which was moderately sensitive to levofloxacin and tetracycline,while sensitive to piperacillin,norfloxacin,streptomycin and chloramphenicol. Conclusion Goose-derived Lactobacillus paracasei subspecies tolerance H and Bacillus subtilis KA9 have good acid resistance and bile salt resistance,which are expected to be candidate strains for goose-derived microecological preparations.
RESUMO
Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.
RESUMO
ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.
