The diagnosis of hematological disorders is currently established from the combined results of different tests, including those assessing morphology (M), immunophenotype (I), cytogenetics (C), and molecular biology (M) (collectively known as the MICM classification). In this workflow, most of the results are interpreted manually (i.e., by a human, without automation), which is expertise-dependent, labor-intensive, time-consuming, and with inherent interobserver variability. Also, with advances in instruments and technologies, the data is gaining higher dimensionality and throughput, making additional challenges for manual analysis. Recently, artificial intelligence (AI) has emerged as a promising tool in clinical hematology to ensure timely diagnosis, precise risk stratification, and treatment success. In this review, we summarize the current advances, limitations, and challenges of AI models and raise potential strategies for improving their performance in each sector of the MICM pipeline. Finally, we share perspectives, highlight future directions, and call for extensive interdisciplinary cooperation to perfect AI with wise human-level strategies and promote its integration into the clinical workflow.

Objective To investigate the clinical and pathological features of adenoid basal cell carcinoma(ABC),adenoid cystic carcinoma(ACC),and basaloid squamous cell carcinoma(BSCC)with basaloid charac-teristics and improve the diagnostic and differential diagnostic ability of clinicians and pathologists for these lesions.Methods A retrospective study was conducted on the clinical and pathological data of 4 cases of ABC,1 case of ACC,and 3 cases of BSCC diagnosed and treated at Shenzhen Maternal and Child Health Hospital,Southern Medical University from April 2018 to December 2022.Pathological slides were reviewed and relevant literature was analyzed and summarized.Results All three types of tumors were common in postmenopausal women and were associated with high-risk HPV infection.ABC was a low-grade cancer and patients were often clinically asymp-tomatic.It was usually detected incidentally during cervical screening due to cytological abnormalities,or after cervical cone biopsy or hysterectomy for HSIL.It presented as superficial cervical infiltration and clinical staging was often early.ACC and BSCC were intermediate to high-grade cancers and they often presented with postmenopausal vaginal bleeding.A visible mass was observed on the cervix.The clinical staging was intermediate to advanced.The three types of lesions could coexist.Careful observation of the morphological characteristics and immunohistochemical staining could help with differential diagnosis.None of the 8 patients experienced recurrence or metastasis during follow-up.Conclusion Cervical ABC,ACC and BSCC are rare and they originate from reserve cells.They share the similarities in clinical and pathological morphology,but differ in treatment and prognosis.So,accurate differen-tiation among them has important clinical significance.

BACKGROUND:The type of graft selected during anterior cruciate ligament revision is considered one of the main factors affecting the postoperative outcome,but there are few reports on the comparison between different graft materials. OBJECTIVE:To explore the medium-to-long-term clinical efficacy after anterior cruciate ligament revision with autologous ligament,allogeneic ligament,and LARS artificial ligament. METHODS:A total of 67 patients with the first anterior cruciate ligament revision admitted to the Department of Joint and Sports Medicine,The Second Hospital of Tangshan from May 2011 to May 2020 were selected,including 41 males and 26 females,with a mean age of(45.83±7.39)years.They were divided into three groups according to different grafts used:autologous ligament group(n=24),allogeneic ligament group(n=22),and LARS artificial ligament group(n=21).Follow-up for more than 36 months after revision was performed to evaluate the effect of revision. RESULTS AND CONCLUSION:(1)International Knee Documentation Committee(IKDC)score,Lysholm knee score,and Tegner motor score 1 year after surgery and at the last follow-up in the three groups were higher than those before surgery(P<0.05).There were no significant differences in IKDC score,Lysholm knee score,and Tegner motor score among the three groups 1 year after surgery and the last follow-up(P>0.05).(2)The lateral differences of KT-1000 at 1 year after surgery and the last follow-up among the three groups were lower than those before surgery(P<0.05).The lateral difference of KT-1000 and the positive rate of the axial shift test in the last follow-up of the LARS artificial ligament group were higher than those in the autologous ligament group and allogeneic ligament group(P<0.05).(3)At the last follow-up,X-ray films showed no obvious enlargement of the reconstructed bone tunnel and no obvious failure of the graft fixation device.There was no obvious aggravation of osteoarthritis,but bone density decreased significantly in some elderly patients.(4)These findings suggest that anterior cruciate ligament revision with LARS artificial ligaments can obtain good initial stability,but with the extension of time,the stability of partial cases tends to decrease,even with reconstructed ligament failure.Both allogeneic and autogenous ligaments can obtain good clinical efficacy in anterior cruciate ligament revision.

Objective: To investigate the effect of Guangdong Shenqu (GSQ) on intestinal flora structure in mice with food stagnation through 16S rDNA sequencing. Methods: Mice were randomly assigned to control, model, GSQ low-dose (GSQL), GSQ medium-dose (GSQM), GSQ high-dose (GSQH), and lacidophilin tablets (LAB) groups, with each group containing 10 mice. A food stagnation and internal heat mouse model was established through intragastric administration of a mixture of beeswax and olive oil (1:15). The control group was administered normal saline, and the model group was administered beeswax and olive oil to maintain a state. The GSQL (2 g/kg), GSQM (4 g/kg), GSQH (8 g/kg), and LAB groups (0.625 g/kg) were administered corresponding drugs for 5 d. After administration, 16S rDNA sequencing was performed to assess gut microbiota in mouse fecal samples. Results: The model group exhibited significant intestinal flora changes. Following GSQ administration, the abundance and diversity index of the intestinal flora increased significantly, the number of bacterial species was regulated, and α and β diversity were improved. GSQ administration increased the abundance of probiotics, including Clostridia, Lachnospirales, and Lactobacillus, whereas the abundance of conditional pathogenic bacteria, such as Allobaculum, Erysipelotrichaceae, and Bacteroides decreased. Functional prediction analysis indicated that the pathogenesis of food stagnation and GSQ intervention were primarily associated with carbohydrate, lipid, and amino acid metabolism, among other metabolic pathways. Conclusion The digestive mechanism of GSQ may be attributed to its role in restoring diversity and abundance within the intestinal flora, thereby improving the composition and structure of the intestinal flora in mice and subsequently influencing the regulation of metabolic pathways.

Objective Based on TLR4/NF-κB/MLCK pathway,the therapeutic effect and mechanism of Baihe Dihuang Decoction on insomnia with intestinal flora disturbance in mice induced by p-chlorophenlalanine(PCPA)and multi-factor stimulation were studied.The aim is to provide theoretical basis for clinical use.Methods Eighty-four KM mice were randomly divided into normal group,model group,positive group(Diazepam,1.38 mg·kg-1),Baihe group(2.25 g·kg-1),Dihuang group(2.25 g·kg-1)and Baihe Dihuang Decoction group(4.5 g·kg-1).Insomnia mouse model was established by intraperitoneal injection of PCPA for 2 days combined with 4 weeks of multi-factor stimulation,including stimulating the tail with forceps clip for 2 minutes,reversing day and night for 24 hours,wetting the padding for 24 hours,tilting the cage at 45° for 24 hours,alternating the cages for 24 hours,fasting food for 24 hours,and getting cold bath for 3 minutes,etc.After successfully modeling,corresponding drug treatment was given.The anxiety-like behavior of mice was observed by elevated cross maze system.The latency and duration of sleep were observed by righting reflex experiment.16sRNA sequencing was used to analyze the composition and structure of intestinal flora in mice.The concentration changes of γ-aminobutyric acid(GABA),glutamic acid(Glu),tryptophan(Trp),5-hydroxytryptophan(5-HTP)and 5-hydroxytryptamine(5-HT)in brain and colon were detected by liquid chromatography-mass spectrometry(LC-MS).Immunohistochemical method was used to detect the expressions of zona atresia protein 1(ZO-1)and Occludin in colon.Real-time fluorescence quantitative PCR(qRT-PCR)was used to detect the genes including interleukin-1β(IL-1β),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),ZO-1,Occludin,Toll-like receptor 4(TLR4),nuclear factor κB(NF-κB)and myosin light chain kinase(MLCK)in colonic tissue.Western Blot was used to detect the expressions of TLR4,NF-κB,phosphorylated nuclear factor κB(p-NF-κB),MLCK,myosin light chain(MLC)and phosphorylated myosin light chain(p-MLC)in colonic epithelial tissue.Results Compared with the normal group,the distance of entering the open arm and the duration of stay in the open arm of model group in the elevated cross maze were significantly shortened(P＜0.05).The sleep latency was significantly prolonged,and the sleep duration was significantly shortened(P＜0.05).The richness and uniformity of intestinal flora were decreased(P＜0.05,P＜0.01).The concentration of neurotransmitters GABA,Trp,5-HTP and 5-HT in the brain decreased significantly(P＜0.01),while the concentration of Glu increased significantly(P＜0.01).The concentration of GABA and Glu in colon decreased significantly(P＜0.01),while the concentration of Trp,5-HTP and 5-HT increased significantly(P＜0.01).The expression levels of inflammatory factors IL-1β,IL-6 and TNF-α in colonic tissue were significantly increased(P＜0.01),and the expression levels of ZO-1 and Occludin genes and proteins were significantly decreased(P＜0.01).The gene expression levels of TLR4,NF-κB and MLCK were significantly increased(P＜0.01),and the protein expression levels of TLR4,p-NF-κB,MLCK and p-MLC were significantly increased(P＜0.01).Compared with the model group,Baihe Dihuang Decoction could significantly prolong the distance of entering the open arm and the duration of stay in the open arm of insomnia mice in the elevated cross maze(P＜0.05).The sleep latency was significantly shortened,and the sleep duration was significantly increased(P＜0.05).The richness and uniformity of intestinal flora were increased(P＜0.05,P＜0.01).The concentration of neurotransmitters GABA,Trp,5-HTP and 5-HT in brain was increased(P＜0.05,P＜0.01),and the concentration of Glu was decreased(P＜0.01).The concentration of GABA and Glu in colon was increased(P＜0.01),while the concentration of Trp,5-HTP and 5-HT was decreased(P＜0.05,P＜0.01).The expression levels of IL-1β,IL-6 and TNF-α genes were down-regulated(P＜0.01),the expression levels of ZO-1 and Occludin genes and proteins were up-regulated(P＜0.01),TLR4,NF-κB,MLCK gene expression levels and TLR4,p-NF-κB,MLCK,p-MLC protein expression levels were down-regulated in the pathway(P＜0.01).Conclusion Baihe Dihuang Decoction can effectively treat insomnia with intestinal flora disorders.Its mechanism of action may be related to the regulation of brain and intestinal neurotransmitter disorders,down-regulating TLR4/NF-κB/MLCK signaling pathway,and up-regulating tight junction proteins expression,reducing inflammatory responses,and then repairing the mechanical barrier of intestinal mucosa.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases. In this study, we employed multiregional microdissection sequencing to integrate morphological features with genomic profiling. This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues. We identified a distinct and robustly consistent CNV pattern in 93.75% (30/32) of OM cases, characterized by CNV gain events in chromosomes 4, 5, 8, 10, 12, 16, 17, 20, and 21. This pattern significantly differed from the CNV patterns observed in DP, DF, and OF. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated potential links between this CNV patterns and the calcium signaling pathway and salivary secretion, while Gene Ontology (GO) term analysis implicated CNV patterns in tumor adhesion, tooth development, and cell proliferation. Comprehensive CNV analysis accurately identified a case that was initially disputable between OF and OM as OM. Our findings provide a reliable diagnostic clue and fresh insights into the molecular biological mechanism underlying OM.

Objective:To evaluate the effect of inhaled medication compliance intervention in elderly patients with chronic obstructive pulmonary disease (COPD) based on integrated theory of health behavior change.Methods:A total of 117 elderly COPD patients who visited Respiratory Department of Beijing Chaoyang Hospital Affiliated to Capital Medical University from July to December 2021 were selected by the convenient sampling method. According to the random number table method, they were divided into the experimental group and the control group. 7 cases fell off during follow-up, and a total of 110 cases were finally included in the study, of which 55 cases were in the experimental group and 55 cases in the control group. The control group adopted the conventional health education method, while the experimental group adopted the intervention plan of inhalation medication compliance of elderly COPD patients based on the integrated theory of health behavior change. The accuracy of inhalation device use, inhalant medication compliance, forced expiratory volume in the first second (FEV 1) and Chronic Obstructive Pulmonary Diseases Assessment Test (CAT) scores were compared between the two groups before intervention and 3 months after intervention. Results:After 3 months of intervention, the inhalation device use accuracy, inhalation medication compliance in experimental group were higher than those in the control group, the score of CAT in experimental group was lower than that in the control group, the differences were statistically significant ( P<0.05). There was no statistically significant difference in FEV 1 between two groups ( P>0.05) . Conclusions:The intervention plan for inhalation medication compliance in elderly patients with chronic obstructive pulmonary disease based on the integrated theory of health behavior changes can improve their inhalation medication compliance and improve their quality of life.

Objective:To discuss how to avoid the occurrence of adverse events and provides basis for improving the extracorporeal membrane oxygenation (ECMO) transport safety management to formulate the corresponding preventive measures through analyzing the causes and characteristics of adverse events in transport of ECMO.Methods:By using a self-designed ECMO transport observation table to collect data, with a retrospective study of adverse events in patients with ECMO transport in ECMO center of Beijing Chaoyang Hospital from January 2013 to June 2017, carrying out classification and analysis according to the causes of adverse events and the potential risks of the patients, thus put forward the feasible preventive measures.Results:There were 53 cases of ECMO transport in study period, with 18 cases (33.96%) of adverse events, among which the incidence of adverse events in inner-hospital transport was 34.21% (13/38) and that in inter-hospital transport was 33.33% (5/15). There was no patient died in ECMO transport. In the adverse events of ECMO transport, the main causes were related to transport staff, transport equipment and patient, which accounting for 1/3 of each. Among them, the most prominent was 4 cases (22.22%) of equipment lacking and 3 cases of battery and power supply (16.67%). In classification according to the risk degree of patients, 6 cases (33.33%) of third grade risk were found.Conclusions:It is safe and feasible to carry out ECMO transport in inner-hospital transport and inter-hospital transport based on ECMO transport team and transport process of this hospital. However the unexpected events of high risk or crisis of life is inevitable in ECMO transport. Through standardized training for ECMO team, with full assessment before transport, by the use of ECMO checklist and strict implementation of various transport processes and specifications, the incidence of adverse events in ECMO transport may be reduced.
