ABSTRACT
Objectives: This study aims to discuss the clinical manifestations and treatment of Familial hemophagocytic lymphohistiocytosis (FHL) caused by a mutation in the UNC13D gene. Methods: A 6-year-old female child presented with unexplained febricity, splenomegaly, pancytopenia, hemophagocytic lymphohistiocytosis in bone marrow, decreased NK cell activity, soluble CD25 levels > 44000ng/ml. Genetic sequencing revealed a mutation in the UNC13D gene. Additionally, the patient experienced intermittent fever with seizures characterized by involuntary twitching of the left upper limb. Head magnetic resonance imaging (MRI) showed white matter lesions. Results: According to the HLH-2004 diagnostic criteria revised by the International Society of Histiocytosis the patient was diagnosed with FHL. Despite receiving HLH-2004 treatment, the disease relapsed. However, after a salvage allogeneic Hematopoietic Stem Cell Transplant (HSCT), febricity, abnormal blood cells, and neurological symptoms significantly improved. Conclusions: Prompt performance of allogeneic HSCT is crucial upon diagnosis of FHL, especially when neurological involvement is present.

Triple-negative breast cancer (TNBC) is a nasty disease with extremely high malignancy and poor prognosis. Annexin A3 (ANXA3) is a potential prognosis biomarker, displaying an excellent correlation of ANXA3 overexpression with patients' poor prognosis. Silencing the expression of ANXA3 effectively inhibits the proliferation and metastasis of TNBC, suggesting that ANXA3 can be a promising therapeutic target to treat TNBC. Herein, we report a first-in-class ANXA3-targeted small molecule (R)-SL18, which demonstrated excellent anti-proliferative and anti-invasive activities to TNBC cells. (R)-SL18 directly bound to ANXA3 and increased its ubiquitination, thereby inducing ANXA3 degradation with moderate family selectivity. Importantly, (R)-SL18 showed a safe and effective therapeutic potency in a high ANXA3-expressing TNBC patient-derived xenograft model. Furthermore, (R)-SL18 could reduce the β-catenin level, and accordingly inhibit the Wnt/β-catenin signaling pathway in TNBC cells. Collectively, our data suggested that targeting degradation of ANXA3 by (R)-SL18 possesses the potential to treat TNBC.
ABSTRACT
Objective:To compare the clinical efficacy and safety of intra-articular injection of platelet rich plasma and hyaluronic acid in the treatment of knee osteoarthritis.Methods:The relevant literatures including the randomized control study of intra-articular injection of platelet rich plasma and hyaluronic acid in the treatment of knee osteoarthritis published from January 2010 to December 2021 were searched. The bias risk of the included literatures was evaluated by Revman 5.3 software, and the data were processed and analyzed by Stata 16.0 software. The weighted mean difference ( WMD) was calculated for the difference ofefficacy indexes, and the difference was compared by t-test. The odds ratio ( OR) was calculated for the difference of safety index, and the difference was compared by t-test. Results:① A total of 10 literatures were included, all of which were in English. ② A total of 921 patients were included in the study, of which 479 patients were treated with intra-articular injection of platelet rich plasma and 442 patients were treated with intra-articular injection of hyaluronic acid. ③ Comparing the VAS scores of platelet rich plasma injection and hyaluronic acid injection, the visual analogue scale (VAS) scores of platelet rich plasma injection patients were significantly lower than those of hyaluronic acid injection patients after 6 and 12 months of injection treatment, and the difference was statistically significant [ WMD(95% CI)=-0.66(-1.25, -0.77), P=0.029; WMD(95% CI)= -0.90(-1.51, -0.29), P=0.004]. ④ The specific performance was that the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score of patients injected with platelet rich plasma after 6 and 12 months of injection treatment was significantly lower than that of patients injected with hyaluronic acid [ WMD(95% CI)=-0.76(-1.06, 0.45), P<0.001; WMD(95% CI)=-1.35(-2.05, -0.65), P<0.01]; After 3, 6 and 12 months of injection treatment, the WOMAC stiffness score of patients injected with platelet rich plasma was significantly lower than that of patients injected with hyaluronic acid [( WMD(95% CI)=-0.37(-0.66, -0.08), P=0.011; WMD(95% CI)=-0.30(-0.57, -0.04), P=0.023; WMD(95% CI)=-0.62(-0.92, -0.33), P<0.001]; After 3, 6 and 12 months of injection treatment, the WOMAC function score of patients injected with platelet rich plasma was significantly lower than that of patients injected with hyaluronic acid [ WMD(95% CI)=-1.90 (-2.53, -1.27), P<0.001; WMD(95% CI)=-5.77(-9.20, -2.34), P=0.001; WMD(95% CI)=-5.72(-8.62, -2.82), P<0.001]. ⑤There was no significant difference in the incidence of adverse events between the two intra-articular injection methods [ OR(95% CI)=1.28(0.68, 2.42), P=0.440]. Conclusion:Compared with intra-articular injection of hyaluronic acid, the short-term clinical efficacy of injection of platelet rich plasma is equivalent to that of injection of hyaluronic acid, but the long-term clinical efficacy is better, and the safety of the two methods is similiar.
