Metabolic associated fatty liver disease （MAFLD） is a common chronic liver disease worldwide， and timely and precise intervention can delay disease progression and significantly reduce the risk of serious complications such as liver fibrosis， liver cirrhosis， and liver cancer. Although traditional liver biopsy combined with metabolic markers is the gold standard， it may cause complications such as pain and bleeding as an invasive examination， which has promoted scientific research to shift its focus to the construction of noninvasive assessment systems. In recent years， noninvasive diagnostic technologies based on multi-dimensional detection strategies have been continuously updated， including serological models， imaging techniques， and clinical algorithms. This article systematically reviews the screening methods for MAFLD during the fibrotic stages F1—F3， especially deep learning models based on artificial intelligence， in order to provide ideas for the early screening of MAFLD， as well as a scientific reference for optimizing disease management strategies.

A 39-year-old male patient with ankylosing spondylitis received adalimumab 40 mg subcutaneously every 2 weeks plus sulfasalazine enteric-coated tablets 0.75 g orally twice daily. Two weeks after the therapy initiation, he received his second adalimumab injection and discontinued sulfasalazine because of skin rashes. Meanwhile, cetirizine 10 mg once daily was given as anti-allergic treatment for 3 days. Six days later, he developed fever and persistent holocranial dull pain. The next day the headache worsened, with one episode of vomiting gastric contents. Cranial magnetic resonance imaging revealed findings consistent with infectious leptomeningeal lesions, and cerebrospinal fluid analysis suggested intracranial infection. Empirical anti-infection therapy with ceftriaxone and ganciclovir, as well as intracranial pressure reduction therapy with 20% mannitol was initiated. Two days later, next-generation sequencing of cerebrospinal fluid identified Neisseria meningitidis as the highly probable pathogen. The therapy regimen was adjusted to ceftriaxone, acyclovir and dexamethasone. After 12 days of treatments, the patient achieved full clinical recovery from meningitis.

ObjectiveThe angiosperm phylogeny group （APG） Ⅳ system is currently the latest angiosperm classification system. The APG system based on DNA sequence can more naturally reflect the phylogeny and evolution of plants， which has been widely recognized and applied in scientific research and teaching of plants in other countries. Through the comparison between the changes in the APG Ⅳ system and the traditional plant classification system， the changes in the taxonomic status of the original plants of traditional Chinese medicine （TCM） in the 2020 edition of Chinese Pharmacopoeia were reviewed. MethodBy referring to the literature in China and abroad， the changes in the taxonomic status of the original plants of TCM recorded in Chinese Pharmacopoeia were sorted out according to the basic groups of angiosperms in the APG Ⅳ system， including the basal group of ANA， the magnoliid and chloranthales， the basal groups of monocots and eudicots， the superrosids， and the superasterids. ResultThere are about 72 species of TCM in the 2020 edition of Chinese Pharmacopoeia. A total of 76 species of the original plants change in family grade according to the APG Ⅳ system. There are 22 species of TCM belonging to the dicotyledon class， involving 26 species of the original plants. It should be placed in front of the differentiation of monocotyledons and eudicotyledons according to the APG Ⅳ system. ConclusionThis paper largely clarifies the change in the taxonomic status of the original plants of TCM in Chinese Pharmacopoeia according to the APG Ⅳ system， which is helpful to the reviewing literature in China and abroad for the original plants of TCM and facilitates the international academic exchange for TCM. It provides a reference for the revision of textbooks such as Botany and Medicinal Botany in Chinese colleges and universities and will lay the foundation for updating the content of Chinese Pharmacopoeia in the future.

Objective To understand the current situation of breastfeeding duration in children aged 0-5 years in Yunnan Province,and to explore the influencing factors of breastfeeding duration.Methods Using the data of the 6th National Health Service Survey in Yunnan Province,1582 children aged 0～5 years in Yunnan Province were selected as the research subjects,and the Kaplan-Meier method and Cox regression were used to analyze the influencing factors of breastfeeding duration.Results The mean duration of breastfeeding for children aged 0～5 years in Yunnan Province was 9.29 months,and region,time of complementary food addition,time of suckling and family income were the main factors influencing the duration of breastfeeding.Conclusion The duration of breastfeeding for children aged 0～5 years in Yunnan Province deviates significantly from the recommendations provided by both the World Health Organization(WHO)and China's child breastfeeding guidelines.Given the current situation,the relevant departments must enhance their focus on this issue.

In the field of biomedicine,two-dimensional(2D)cell lines and animal models have played an im-portant role in the study of cell pathways and drug targets.However,due to species differences between humans and other animals,and the lack of hierarchy,cellular diversity,and cell-cell or cell-matrix interactions,2D cell lines could not ful-ly reflect what cells actually look like in the human body.Organoids are three-dimensional(3D)in vitro culture models de-rived from autologous tissue stem cells,which make up for the defects of 2D culture and can simulate the structure and function of real human organs to a certain extent,providing new ideas for disease diagnosis and treatment.Among them,lung organoids(LO)are a typical case studying the development process of human lung and the generation principle of lung diseases.Relevant studies have provided help for the treatment of pulmonary fibrosis,lung cancer,lung injury and other diseases.This paper aims to summarize and analyze the research progress of lung organoids in recent years,and fur-ther summarize the application of LO in the diagnosis and treatment of lung diseases.

Objective To examine the compliance of and factors affecting target attainment of serum trough concentration of norvancomycin in ICU patients,and the effects of different trough concentrations on clinical efficacy and renal impairment.Methods Adult patients admitted to the Department of Critical Care Medicine of Huangshan People's Hospital and receiving intravenous infusion of norvancomycin from January 2020 to December 2022 were included.The dosing regimens and steady-state trough concentrations of norvancomycin were analyzed.The clinical efficacy and renal impairment were compared between different trough concentration levels.The compliance of trough concentration in critically ill patients with different renal functions was examined.Logistic regression analysis was performed to profile the factors possibly affecting the trough concentration of norvancomycin.Results A total of 97 patients were included.The target serum trough concentration(10-20 mg/L)was reached in only 33.0％(32/97)of the critically ill patients.The serum trough concentration was below the target in 51.5％(50/97)of the patients,above the target in 15.5％of the patients.The clinical cure rate and incidence of renal impairment were significantly different among the three groups of patients with different trough concentrations(P＜0.05).The compliance with target serum trough concentration varied with different renal function tests(P＜0.05).Augmented renal clearance and normal renal function were associated with trough concentrations lower than the target.As renal dysfunction got worse,serum trough concentration was more probably higher than the target(P＜0.05).Univariate analysis showed that daily dose,age,gender,height,weight,body mass index(BMI),APACHE Ⅱ score,sequential organ failure assessment(SOFA)score,blood creatinine,urea nitrogen,procalcitonin,concomitant septic shock,and use of norepinephrine were significantly correlated with trough concentrations of norvancomycin(P＜0.05).Multivariate logistic regression analysis indicated that age,SOFA score,blood urea nitrogen,gender,and norepinephrine use were independent factors affecting the serum trough concentration of norvancomycin(P＜0.05).Conclusions The serum trough concentration of norvancomycin varied with renal function states in ICU patients.It is difficult to achieve the steady-state target trough concentration(10-20 mg/L).The clinical cure rate is lower when the trough concentration is lower than the target.As the trough concentration increases,the incidence of renal impairment increases.Age,SOFA score,urea nitrogen,gender,and norepinephrine use are independent factors affecting the serum trough concentrations of norvancomycin.

Panapoptosis is a new focus of current research, which is essentially the inflammatory programmed cell death, with the common characteristics of pyrodeath, apoptosis and necrotic apoptosis. Panapoptosis is closely related to many diseases, such as infectious diseases, tumors, neurodegenerative diseases and so on. As a pathway of recognition and activation by the immune system, panapoptosis plays an important role in controlling the spread of inflammation and disease progression, although the specific regulatory mechanism is not yet clear. This review aims to explore the role of panapoptosis in the pathogenesis and development of cellular inflammation and diseases, and seek potential intervention targets to provide new strategies for clinical disease treatment.

OBJECTIVE To reveal the role of the basal forebrain(BF)GABAergic neurons in the regulation of isoflurane anesthesia and to elucidate the underlying neural pathways.METHODS The activity of BF GABAer-gic neurons was monitored during isoflurane anesthesia using a genetically encoded calcium indicator in Vgat-Cre mice of both sexes.The activity of BF GABAer-gic neurons was manipulated by chemogenetic and opto-genetic approaches.Sensitivity,induction time and emer-gence time of isoflurane anesthesia were estimated by righting reflex.The electroencephalogram(EEG)power and burst-suppression were monitored by EEG recording.The effects of activation of GABAergic BF-thalamic reticu-lar nucleus(TRN)pathway on isoflurane anesthesia were investigated with optogenetics.RESULTS The activity of BF GABAergic neurons was generally inhibited during isoflurane anesthesia,obviously decreased during the induction of anesthesia and gradually restored during the emergence from anesthesia.Activation of BF GABAergic neurons with chemogenetics and optogenetics promoted behavioral emergence from isoflurane anesthesia,with decreased sensitivity to isoflurane,delayed induction and accelerated emergence from isoflurane anesthesia.Optogenetic activation of BF GABAergic neurons prom-oted cortical activity during isoflurane anesthesia,with decreased EEG delta power and burst suppression ratio during 0.8%and 1.4%isoflurane anesthesia,respectively.Similar to the effects of activating BF GABAergic cell bod-ies,photostimulation of BF GABAergic terminals in the TRN also strongly promoted cortical activation and behav-ioral emergence from isoflurane anesthesia.CONCLU-SION The GABAergic neurons in the BF is a key neural substrate for general anesthesia regulation that facilitates behavioral and cortical emergence from general anesthe-sia via the BF-TRN pathway.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.
