In the period of digital transformation of the medical service model， maintaining algorithm justice for medical artificial intelligence possesses multiple value implications. However， practical dilemmas exist at different stages of achieving this value goal. At the initial stage of diagnosis and treatment decision-making， there is a risk of imbalance in patients’ rights and interests， such as weakened effectiveness of patients’ right to informed consent， as well as low synergy between rights and interests protection and technological innovation. In the process of diagnosis and treatment decision-making， the algorithmic model is constrained by the technological bottleneck in the underlying application， deviating from the legal track of technological neutrality. After the diagnosis and treatment decision-making is generated， it triggers a crisis in the remedy of patients’ rights and interests and breeds the phenomenon of an ambiguous definition of subject qualification and attribution principle. In this regard， it is essential to establish a preemptive safeguard system focusing on the protection of patients’ rights and interests， set technological fairness standards， and shape review norms of technological neutrality. The aim is to ensure the equalization of remedy channels for patients’ rights and interests， promote the fairness in the proportion of responsibilities among multiple subjects， and thereby safeguard the digital justice in the field of intelligent diagnosis and treatments.

Abstract Inhibitor of DNA binding 1(ID1) is a crucial regulator of cell differentiation and plays a significant role in maintaining normal hematopoietic differentiation and development. Due to the lack of DNA-binding motif, ID1 functions as a dominant-negative inhibitor of basic helix-loop-helix factors to antagonize their abilities to bind to DNA and transcriptionally regulate target genes. Abnormal expression of ID1 is strongly associated with various hematologic disorders, including myeloid and lymphoblastic leukemia, multiple myeloma and myeloproliferative neoplasms. ID1 acts as a potential oncogene by participating in multiple signaling pathways that promote the malignant proliferation, invasion and therapy resistance in leukemic cells. Significant strides have yielded promising antileukemic effects of ID1 inhibitors, both alone and in combination with targeted therapies against oncogenic signaling pathways. Here, we review the relationship between ID1 expression and the initiation and progression of blood disorders, and summarize the clinical significance of ID1 as a novel therapeutic target and potential prognostic biomarker for hematologic malignancies.

Objective To observe the ultrasound biomicroscopy(UBM)findings of lacrimal canaliculitis.Methods Totally 35 patients with single eye lacrimal canaliculitis who underwent surgical treatment were retrospectively enrolled,including 3 cases of simple superior lacrimal tubule abnormalities,19 cases of simple inferior lacrimal tubule abnormalities and 13 cases with both superior and inferior lacrimal tubules.UBM data and postoperative laboratory examination results were comparatively analyzed.Results The detection rate of UBM for lacrimal canaliculitis was 100％.Abnormal coenobium-like structures in lacrimal tubule were characterized by elliptical or irregular low echo,with unclear boundaries and uneven internal echo,some with punctate high echoes,while polyps presented as oval or strip-shaped high echo with clear boundaries and uniform internal echoes in UBM.UBM findings of tumor like hyperplasia were similar to abnormal coenobium-like structures but with relatively uniform internal echoes.Sulfur particles extracted from lacrimal tubule revealed no fungi in 35 cases by postoperation pathology,while actinomycete was observed in 24 cases,with UBM finding of abnormal coenobium-like structures and punctate high echoes.Conclusion UBM findings of lacrimal canaliculitis had certain characteristics.Coenobium-like structures and punctate high echoes in lacrimal tubule could be observed after infection of actinomycete.

Objective:To explore changes of acid-base metabolism in the brain tissue of patients with chronic ischemic cerebrovascular disease (CICVD) using MRI amide proton transfer-weighted (APTw) imaging.Methods:This was a cross-sectional study. From January 2021 to July 2022, thirty-nine patients with CICVD at West China Hospital, Sichuan University were retrospectively included. All patients received CT perfusion (CTP) and APTw imaging. NeuBrainCARE brain perfusion software was used to analyze the impaired perfusion sites and measure the mean transit time (MTT) and time to peak (TTP). Standard spatial matching between CTP and APTw images was performed to measure the APTw values of the same sites. For comparison with normal tissue, APTw values were measured for normal-appearing white matter (NAWM) in the ipsilateral cerebral hemisphere, the contralateral cerebral hemisphere, and the ipsilateral cerebellar hemisphere in areas of impaired perfusion. ANOVA was used to compare the APTw values of impaired perfusion brain tissue, ipsilateral cerebral NAWM, contralateral cerebral NAWM, and ipsilateral cerebellar NAWM. The Bonferroni method was used to correct for multiple comparisons. Pearson correlation coefficient was used to analyze the correlation between APTw values and MTT and TTP in the cerebral tissue with impaired perfusion.Results:In 39 patients with CICVD, both the mean and minimum APTw values of cerebral tissue with impaired perfusion were significantly lower than those in the NAWM of the ipsilateral cerebral hemisphere, the contralateral cerebral hemisphere, and the ipsilateral cerebellar hemisphere ( P<0.001). In the NAWM of the cerebellar hemispheres with unimpaired perfusion, both the mean and minimum APTw values were significantly higher than those in the ipsilateral cerebral hemispheres and the contralateral cerebral hemisphere ( P<0.001). Correlation analysis showed that MTT was significantly negatively correlated with both the mean APTw and the minimum APTw ( r values were -0.90 and -0.82, P<0.001). TTP was significantly negatively correlated with both the mean APTw and the minimum APTw ( r values were -0.86 and -0.78, P<0.001). Conclusion:APTw value can reflect acidosis in cerebral tissue with impaired perfusion in patients with CICVD.

A case of adult spindle cell sarcoma with NTRK3-C22orf34 gene fusion is reported. The patient, a 35-year-old-male, developed lateral swelling of the right thigh without obvious inducement 7 months before admission and was not accompa-nied by limited movement. The patient was diagnosed with adult spindle cell sarcoma with NTRK3-C22orf34 gene fusion based on the medical history, imaging findings, histomorphology, immunohistochemistry and molecular phenotype. The patients underwent tumor resection without drug-targeted therapy and followed up for 8 months after tumor resection and survived without tumor. In recent years, the number of adult spindle cell sarcomas with neurotrophic tyrosine kinase receptor 3 (NTRK3) gene fusions have been increasing year by year, and most of them are difficult to diagnose based on HE sections due to the varied morphology and small number of these tumors. With the wide application of high-throughput sequencing in soft tissue tumors, the difficulty of diagnosis of spindle cell tumors with the NTRK fusion gene has decreased. High-throughput sequencing of the patient showed that NTRK3-C22orf34 (mutation abundance 5%) gene fusion combined with BRCA1 (mutation abundance 15%) rearrangement and deletion of CDKN2A and TP53 genes were found to be of definite or potential clinical significance. The morphologic spectrum of NTRK fusion spindle cell tumors, especially sarcomas, is still evolving. Treatment of NTRK fusion gene spindle cell tumors is based on surgical resection in combination with tropomyosin receptor kinase (TRK) inhibitors. The emergence of secondary or acquired resistance is primarily associated with point mutations associated with the structural domain of the kinase, and mutations may reduce the efficacy of TRK inhibitors.
