OBJECTIVES: To evaluate the efficacy and safety of avatrombopag in promoting platelet engraftment after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children, compared with recombinant human thrombopoietin (rhTPO). METHODS: A retrospective analysis was conducted on 53 pediatric patients who underwent allo-HSCT at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences from April 2023 to August 2024. Based on medications used during the periengraftment period, patients were divided into two groups: the avatrombopag group (n=15) and the rhTPO group (n=38). RESULTS: At days 14, 30, and 60 post-transplant, platelet engraftment was achieved in 20% (3/15), 60% (9/15), and 93% (14/15) of patients in the avatrombopag group, and in 39% (15/38), 82% (31/38), and 97% (37/38) in the rhTPO group, respectively. There were no significant differences between the two groups in platelet engraftment rates at each time point, cumulative incidence of platelet engraftment, overall survival, and relapse-free survival (all P>0.05). Multivariable Cox proportional hazards analysis indicated that acute graft-versus-host disease was an independent risk factor for delayed platelet engraftment (P=0.043). CONCLUSIONS In children undergoing allo-HSCT, avatrombopag effectively promotes platelet engraftment, with efficacy and safety comparable to rhTPO, and represents a viable therapeutic option.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Streptococcus anginosus group(SAG)used to be considered as normal oral flora.With the advance-ment of diagnostic techniques,an increasing number of case reports confirm that SAG group can be an opportunistic pathogen causing a series of fatal infection.Therefore,this article reviews the diseases caused by SAG as opportu-nistic pathogens and its related pathogenic mechanisms.

Objective To observe the clinical efficacy of regulating the spine and unblocking governor vessel acupuncture combined with Cobamamide intramuscular injection in the treatment of lumbar disc herniation(LDH).Methods A total of 124 patients with LDH were randomly divided into observation group and control group,62 cases in each group,and the control group was given conventional treatment combined with Cobamamide intramuscular injection.The observation group was treated with regulating the spine and unblocking governor vessel acupuncture on the basis of the treatment of the control group,and both groups were treated for one month continuously.After one month of treatment,the clinical efficacy of the two groups was evaluated,and the changes of Visual Analogue Scale(VAS)score,Japanese Orthopaedic Association(JOA)score,lumbar Oswestry Disability Index(ODI)score and lumbar range of motion,including Lumbar flexion and extension,rotation,lateral flexion mobility,were observed in the two groups before and after treatment.Serum thromboxane B2(TXB2),interleukin-1β(IL-1β),and interleukin-10(IL-10)levels were compared between the two groups before and after treatment.And the occurrence of adverse reactions in the two groups was evaluated.Results(1)The total effective rate was 91.94%(57/62)in the observation group and 79.03%(49/62)in the control group.The efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the scores of VAS,JOA and ODI of the patients in the two groups were improved significantly(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,with a statistically significant difference(P＜0.05).(3)After treatment,the lumbar flexion and extension,rotation and lateral flexion mobility of patients in the two groups were improved significantly(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,with statistically significant differences(P＜0.05).(4)After treatment,the levels of serum TXB2,IL-1β,and IL-10 of patients in the two groups were significantly improved(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,with statistically significant differences(P＜0.05).(5)Comparison of the incidence of adverse reactions between the observation group and the control group showed that the difference was not statistically significant(P＞0.05).Conclusion Regulating the spine and unblocking governor vessel acupuncture combined with Cobamamide intramuscular injection in the treatment of LDH can significantly alleviate pain of the patients,improve their lumbar function and range of motion,and promote the expression of serum IL-10 and inhibit the expression of TXB2 and IL-1β,which is safe and effective,and the clinical efficacy is remarkable.

OBJECTIVE: To observe the protective effect and mechanism of hydroxyl safflower yellow A (HSYA) from myocardial ischemia-reperfusion injury on human umbilical vein endothelial cells (HUVECs). METHODS: HUVECs were treated with oxygen-glucose deprivation reperfusion (OGD/R) to simulate the ischemia reperfusion model, and cell counting kit-8 was used to detect the protective effect of different concentrations (1.25-160 µ mol/L) of HSYA on HUVECs after OGD/R. HSYA 80 µ mol/L was used for follow-up experiments. The contents of inflammatory cytokines interleukin (IL)-18, IL-1 β, monocyte chemotactic protein 1 (MCP-1), tumor necrosis factor α (TNF-α) and IL-6 before and after administration were measured by enzyme-linked immunosorbent assay. The protein expressions of toll-like receptor, NOD-like receptor containing pyrin domain 3 (NLRP3), gasdermin D (GSDMD) and GSDMD-N-terminal domain (GSDMD-N) before and after administration were detected by Western blot. NLRP3 inflammasome inhibitor cytokine release inhibitory drug 3 sodium salt (CRID3 sodium salt, also known as MCC950) and agonist were added, and the changes of NLRP3, cysteine-aspartic acid protease 1 (Caspase-1), GSDMD and GSDMD-N protein expressions were detected by Western blot. RESULTS: HSYA inhibited OGD/R-induced inflammation and significantly decreased the contents of inflammatory cytokines IL-18, IL-1 β, MCP-1, TNF-α and IL-6 (P<0.01 or P<0.05). At the same time, by inhibiting NLRP3/Caspase-1/GSDMD pathway, HSYA can reduce the occurrence of pyroptosis after OGD/R and reduce the expression of NLRP3, Caspase-1, GSDMD and GSDMD-N proteins (P<0.01). CONCLUSIONS The protective effect of HSYA on HUVECs after OGD/R is related to down-regulating the expression of NLRP3 inflammasome and inhibiting pyroptosis.

Objective: To investigate the clinical features and short-term prognosis of patients with SARS-CoV-2 infection associated acute encephalopathy (AE). Methods: Retrospective cohort study. The clinical data, radiological features and short-term follow-up of 22 cases diagnosed with SARS-CoV-2 infection associated AE in the Department of Neurology, Beijing Children's Hospital from December 2022 to January 2023 were retrospectively analyzed. The patients were divided into cytokine storm group, excitotoxic brain damage group and unclassified encephalopathy group according to the the clinicopathological features and the imaging features. The clinical characteristics of each group were analyzed descriptively. Patients were divided into good prognosis group (≤2 scores) and poor prognosis group (>2 scores) based on the modified Rankin scale (mRS) score of the last follow-up. Fisher exact test or Mann-Whitney U test was used to compare the two groups. Results: A total of 22 cases (12 females, 10 males) were included. The age of onset was 3.3 (1.7, 8.6) years. There were 11 cases (50%) with abnormal medical history, and 4 cases with abnormal family history. All the enrolled patients had fever as the initial clinical symptom, and 21 cases (95%) developed neurological symptoms within 24 hours after fever. The onset of neurological symptoms included convulsions (17 cases) and disturbance of consciousness (5 cases). There were 22 cases of encephalopathy, 20 cases of convulsions, 14 cases of speech disorders, 8 cases of involuntary movements and 3 cases of ataxia during the course of the disease. Clinical classification included 3 cases in the cytokine storm group, all with acute necrotizing encephalopathy (ANE); 9 cases in the excitotoxicity group, 8 cases with acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) and 1 case with hemiconvulsion-hemiplegia syndrome; and 10 cases of unclassified encephalopathy. Laboratory studies revealed elevated glutathione transaminase in 9 cases, elevated glutamic alanine transaminase in 4 cases, elevated blood glucose in 3 cases, and elevated D-dimer in 3 cases. Serum ferritin was elevated in 3 of 5 cases, serum and cerebrospinal fluid (CSF) neurofilament light chain protein was elevated in 5 of 9 cases, serum cytokines were elevated in 7 of 18 cases, and CSF cytokines were elevated in 7 of 8 cases. Cranial imaging abnormalities were noted in 18 cases, including bilateral symmetric lesions in 3 ANE cases and "bright tree appearance" in 8 AESD cases. All 22 cases received symptomatic treatment and immunotherapy (intravenous immunoglobulin or glucocorticosteroids), and 1 ANE patient received tocilizumab. The follow-up time was 50 (43, 53) d, and 10 patients had a good prognosis and 12 patients had a poor prognosis. No statistically significant differences were found between the two groups in terms of epidemiology, clinical manifestations, biochemical indices, and duration of illness to initiate immunotherapy (all P>0.05). Conclusions: SARS-CoV-2 infection is also a major cause of AE. AESD and ANE are the common AE syndromes. Therefore, it is crucial to identify AE patients with fever, convulsions, and impaired consciousness, and apply aggressive therapy as early as possible.

Circular RNA(circRNA)is a novel type of endogenous non-coding RNA.Most circRNAs act as microRNA(miRNA)sponges to regulate the expression of functional genes.In addition,some circRNAs can be translated and interact with RNA-binding proteins to perform biological functions.The expression of circRNAs is prevalent in tissues and body fluids,and their abnormal expression is related to tumor progression.circRNAs are stable even under the treatment of RNase R because of their circular conformation.As circRNAs have construct stability,wide variety,specific regulation of tumor progression and high expression in body fluids,it is potential for circRNAs to serve as candidate diagnostic,prognostic and therapeutic targets.However,the knowledge about circRNAs remains poor.In addition to the not completely resolved functions and generation mechanisms of circRNAs,the annotations of circRNAs are also waiting for expanding.Here,we review the generation mechanisms,biological functions,and application of circRNAs in tumor research,aiming to provide integrated information for the future research.
