The effect of hetrombopag combined with conventional treatment on immune function and quality of life in patients with severe aplastic anemia.

This study aimed to investigate the effect of hetrombopag combined with conventional treatment on immune function in patients with severe aplastic anemia (SAA). Patients were categorized into the control group (n = 50, receiving conventional treatment only) and experimental group (n = 50, receiving hetrombopag combined with conventional treatment). Before treatment and at weeks 18, 24, and 52 after treatment, the two groups were compared in routine blood test indicators, natural killer (NK) cell activity, and peripheral blood inflammatory factor levels. The overall remission rate and incidence of adverse events were also compared between the two groups. Outpatient or telephone follow-up was performed before treatment and at weeks 18, 24, and 52 after treatment to observe patients' immune function, treatment outcome, quality of life, and adverse events. Hemoglobin (Hb), and platelet count (PLT) (P < 0.05), and a rise in NK cell activity (P < 0.05). Interleukin (IL-10) levels were significantly higher, while IL-6 levels were significantly lower in the experimental group compared to the control group (P < 0.05). After receiving the treatment, all scores of SF-36 domains in both groups were higher than before treatment, particularly with higher scores in the experimental group (P < 0.05). Hetrombopag combined with conventional treatment improved the immune function and hematopoiesis of patients with SAA.

Different Chinese herbal medicine therapy for idiopathic thrombocytopenic purpura: A protocol for systematic review and Bayesian network meta-analysis.

BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) is a common immune system and blood system disease in clinical practice, and it is a hemorrhagic disease caused by immune factors causing platelet destruction and decreasing number of platelets. There is currently no effective treatment plan for ITP. At this stage, glucocorticoid and gamma globulin are mostly used in the treatment of ITP, and some patients use splenectomy to achieve therapeutic purposes, but the various treatment methods are inadequate. At this stage, a large number of randomized controlled studies have reported that Chinese herbal medicine has achieved good curative effect in the treatment of ITP. However, due to the variety of Chinese herbal medicine, there has been no evidence of the effectiveness and safety of Chinese herbal medicine in the treatment of ITP. Because of the above reasons, this study uses the network meta-analysis method based on Bayesian method to compare the clinical efficacy and safety of different kinds of Chinese herbal medicine in the treatment of ITP through direct and indirect comparison, in order to provide evidence-based medical support for the treatment of ITP with Chinese herbal medicine. METHODS: This study uses the method of combining free words with theme words, and using computer to retrieve PubMed, EMbase, The Cochrane Library, WANFANG Database, CNKI, and VIP Database, etc, to collect the randomized control studies on Chinese herbal medicine in the treatment of ITP. The retrieval time is from the establishment of each database to January 2021, and the retrieval languages are Chinese and English. Two researchers independently read the title, abstract and full text of the article to determine whether it is included in the literature; In the event of a disagreement, a third researcher will join the discussion to resolve the disagreement; For the literature that lacks information, trying to contact the original author of the document to supplement it. The literature quality evaluation carried out by using the Stata 14.0 software to draw network and funnel plots, in accordance with the quality evaluation criteria of version 5.1.0 of the Cochrane System Evaluation Manual. Statistical analysis is performed by using ADDIS 1.16.8 software based on the Bayesian model. RESULTS: This study will compare the clinical efficacy and safety of different types of Chinese herbal medicine in the treatment of idiopathic thrombocytopenic purpura through the method of network meta-analysis, and rank the different types of Chinese herbal medicine according to their effectiveness, and the results will be published in a peer-reviewed, high-quality academic journal. CONCLUSION: This study will find effective and safe Chinese herbal medicine for clinical treatment of ITP from the perspective of evidence-based medicine, and benefit more ITP patients.

[Value of MYC, BCL-2 and BCL-6 for Evaluation of Prognosis in Patients with Diffuse Large B Cell Lymphoma].

OBJECTIVE: To analyze the prognostic value of BCL-2, BCL-6 and MYC in patients with diffuse large B cell lymphoma (DLBCL). METHODS: One hundred and sixty three cases of DLBCL in our hospital from March 2012 to March 2015 were selected. The specimens of lymphoma tissue of patients were collected. The expression of BCL-2, BCL-6 and MYC was detected by immunohistochemical method. The fusion of IGH/BCL-2, the gene breakage of BCL-6 and MYC were detected by interphase fluorescence in situ hybridization. The correlation of the expression levels of BCL-2, BCL-6 and MYC with the clinicopathological features and prognosis in the patients with DLBCL was further analyzed. RESULTS: MYC, BCL-2 and BCL-6 showed pale brown or reddish brown positive signals, among them MYC mainly positively expressed on the cell membrane, and BCL-2 mainly expressed on the cytoplasm and local cell membrane, and BCL-6 mainly expressed in the nucleus. The expression level of BCL-2 in ECOG physical status score 2 was higher than that in patients with ＜2 scores, and the expression level of BCL-2 in CD5+ and germinal center B-cell-like (GCB) was significantly higher than that in patients with non-GCB (P＜0.05), and the international prognostic index (IPI) for 3-5 scores at the MYC expression level was significantly higher than that of the 0-2 score (P＜0.05); the expression level of BCL-6 in immune subtype CD5+ and GCB was significantly lower than that in non-GCB (P＜0.05). The results of Cox multivariate analysis showed that the expression level of BCL-2, BCL-6 and MYC significant correlate with the overall survival and progression-free survival (P＜0.05) of the patients with DLBCL. CONCLUSION: BCL-2, BCL-6 and MYC as important molecular markers are of high value for evaluating the prognosis of patients with DLBCL.

[Effects of sodium ozagrel in primary thrombocytosis combined with thrombosis].

This study was aimed to investigate the incidence of thrombosis in patients with primary thrombocytosis (PT) and its correlation with function changes of platelets, and to explore the effect of thromboxane A2 (TXA2) inhibitor-ozagrel sodium on platelet activity and its efficacy for prevention and treatment of thrombosis. The CD62P and PAC-1 levels on platelet surface were detected by flow cytometry; the levels of TXB2 (metabolic product of TXA2) and 6-keto-PGFIalpha (metabolic product of prostacyclin) were detected by FLISA. The function change of platelets and its correlation with thrombosis were observed and compared in PT patients with and without thrombosis. The results indicated that the TXB2, PAC-1 and CD62P level, and TXB2/6-keto-PGF1alpha ratio in PT patients with thrombosis were higher than those in PT patients without thrombosis before treatment with ozagrel sodium (p<0.01). After treatment with ozagrel sodium, the function indexes of platelets such as CD62P, PAC-1, TXB2 and TXB2/6-keto-PGF1alpha except 6-keto-PGF1alpha in PT patients with and without thrombosis decreased obviously (p<0.01), but there was no significant difference in TXB2, 6-keto-PGF1alpha and TXB2/6-keto-PGF1alpha levels between PT patients with and without thrombosis except CD62P and PAC-1. It is concluded that the multi-index of platelets in PT patients with thrombosis are higher than that in PT patients without thrombosis, the activation of platelet function is a high risk factor for thrombosis of PT patients. The ozagrel sodium can obviously reduce the platelet activation, decrease the production of TXA2 and ameliorate the TXB2/6-keto-PGF1alpha ratio. The ozagrel sodium not only possesses therapeutic effect, but also preventive efficacy for thrombosis.
