RESUMO

INTRODUCTION: Therapeutic options to improve myelodysplastic syndrome (MDS)-related cytopenias in patients with lower-risk MDS are limited, and cyclosporin A (CSA) is an available option. METHODS: We retrospectively analysed the clinical data of 153 consecutive patients with lower-risk MDS at our institution from July 1997 to October 2017. Propensity score matching method was used to balance the influence of confounding factors between patients with MDS treated with CSA and other conventional treatments (excluding CSA), and 50 pairs of cases were successfully identified for the final analysis. We assessed response rates, progression-free survival (PFS), overall survival (OS), and factors affecting response and survival. RESULTS: Haematological improvement (HI) was observed in 35 (70%) patients treated with CSA and in 25 (50%) patients treated with conventional therapies (P < 0.05), respectively. Treatment with CSA was a favourable prognostic factor for HI in lower-risk MDS patients of both cohorts in univariate analysis [odds ratio (OR) 2.333, P < 0.05], but not in multivariate analysis. In the multivariate analysis, hypocellular marrow was the only independent prognostic factor for HI in the CSA group (OR 6.259, P < 0.05), and in the overall cohort (OR 3.102, P < 0.05).CSA treatment did not improve PFS or OS (P > 0.05). CONCLUSION: CSA is a safe treatment and can significantly improve cytopenias in a substantial proportion of patients with MDS, especially in individuals with hypocellular bone marrow. However, CSA is not associated with PFS or OS.

RESUMO

Haemophagocytic lymphohistiocytosis (HLH) is a cytokine-driven inflammatory syndrome caused by uncontrolled hypersecretion of inflammatory cytokines. Conventional first-line treatment for HLH included HLH-94 and HLH-2004 regimens. However, quite a few patients do not respond to treatment or cannot tolerate intensive chemotherapy. We reported two cases of HLH, one caused by natural killer (NK)/T-cell lymphoma and another associated with missense variants in the perforin 1 gene. They both received the ruxolitinib plus dexamethasone protocol and had a rapid response to treatment without obvious adverse effects. Our report indicates that treatment with ruxolitinib plus dexamethasone might be a potential option for HLH, and clinical trials warrant further investigation. In addition, the detection of HLH-related genes is necessary for the identification of late-onset familial HLH in certain settings.

RESUMO

Asiatic shrews of the genus Chodsigoa (Soricidae, Eulipotyphla) currently comprise nine species, mostly occurring in southwest China. From May 2017 to August 2020, 11 specimens of Chodsigoa were collected from the Dabie Mountains in Anhui Province, eastern China. Their morphology was compared with other species within the genus and one mitochondrial (cytochrome b) and two nuclear (apolipoprotein B and breast cancer 1) genes were sequenced to estimate the phylogenetic relationships of these specimens. Based on morphological and molecular evidence, these specimens are recognized as a distinct species, Chodsigoadabieshanensis sp. nov., which is formally described here. Morphologically, the new species is most similar to Chodsigoahypsibia, but it is distinguishable from all known congeners by the combination of dark brownish pelage, small size, and relatively short tail. Phylogenetic analyses revealed that C.dabieshanensis sp. nov. forms a phylogenetic lineage sister to the clade containing C.parva + C.hypsibia. The-Kimura 2-parameter genetic distances of the cytochrome b (CYT B) gene between the new species and other nominal Chodsigoa species ranged between 8.6 and 17.6%. The new species is distributed at elevations from 750 to 1250 m in the Dabie Mountains and is geographically distant from other species in the genus.

RESUMO

OBJECTIVE: To explore the clinical efficacy and mechanism of compound Shenlu granule (SLG) treatment in patients with aplastic anemia (AA). METHODS: A total of 89 AA patients were randomly divided into an SLG supportive group (group A, n = 44) and a control group (group B, n = 45) while continuing Western medical management. After 6 months, hemograms, traditional Chinese medicine (TCM) syndrome scores, and overall clinical efficacy rate were assessed. Serum metabolomics characteristics were observed using ultraperformance liquid chromatography-mass spectrometry after SLG intervention. RESULTS: The levels of red blood cell (RBC), hemoglobin (Hb), and platelet (PLT) were increased in both groups after treatment for 6 months (P < 0.05), and in group A, the elevation of PLT became much more significant (P < 0.01). The TCM syndrome score was lower in group A than in group B after treatment (P < 0.05). Metabolomics data showed a significant difference in the patients using SLG after 6 months, and 14 biomarkers were identified. CONCLUSION: SLG supportive treatment showed positive results in patients with AA, and metabolomics data indicated that SLG influenced aminoacyl-tRNA biosynthesis and glycerophospholipid metabolism to gradually return to normal.

RESUMO

Options for anemic lower-risk myelodysplastic syndromes (MDS) without del(5q) after failure of erythropoiesis-stimulating agents (ESAs) are very limited. The effectiveness of second-line treatments is uncertain. We retrospectively reviewed the clinical effectiveness and overall survival (OS) of lower-risk MDS without del(5q) patients exclusively treated with stanozolol (STZ) after failure of epoetin alfa. The response was defined according to the 2006 International Working Group (IWG) criteria. Fifty-six patients were included. The median follow-up time was 55 months (range: 5-156 months). Twenty-seven patients (48.2%) achieved hematologic improvement-erythroid response (HI-E). Higher response rates were observed in patients with lower IPSS-R scores (≤3.5, P = 0.008) and hypocellular bone marrow (P = 0.002). In univariate Cox analysis, HI-E was the strongest factor associated with better OS (P = 0.0003). In multivariate Cox, HI-E, age ≤ 50, and transfusion independence (TI) at the onset of STZ were factors associated with better OS. The estimated 5-year OS was 88.6% (68.7-96.2%) and 33.8% (14.9-54.0%) in responders and non-responders (P < 0.01), respectively. The most common side effects included masculinization and liver damage, but they were manageable with supportive measures and dose adjustments. STZ may be considered an alternative treatment in lower-risk MDS after failure of epoetin alfa.

RESUMO

In this study, we analyzed the complete mitochondrial genome sequence of the hawk moth, Theretra oldenlandiae. The complete mitogenome sequence of T. oldenlandiae was observed to be a circular molecule 15,312 bp long and consisting of 13 protein-coding genes (PCG), 2 ribosomal RNA (rRNA) genes, and 22 transfer RNA (tRNA) genes (GenBank accession number MN885801). The nucleotide composition is biased toward adenine and thymine (80.0% A + T). The A + T-rich region was found between rrnS and trnM, and this entire region was 423 bp long.
