The aim of this study was to update the bryophyte list of Dajinshan Island and provide the scientific basic data for in situ conservation. Based on five field investigations on the island, 67 species belonging to 38 genera in 20 families are reported herein. Compared with historical data for Dajinshan Island, 23 species are newly recorded in the island. Of these, 13 species are newly recorded in Shanghai. One epiphyllous liverwort species, Cololejeunea raduliloba Steph., is newly reported on Dajinshan Island. Taking into account climate change and the physiological and ecological characteristics of bryophytes, the changes in bryophyte species composition on Dajinshan Island are discussed. Our results highlight the importance of timely updating of a regional checklist, when conserving bryophyte biodiversity.
To ascertain the status and promote the utilization and sharing of type specimens in Herbarium of Shanghai Natural History Museum (SHM), the collecting information of normal specimens in SHM with type specimens in specimens of plant resource sharing platform and journal of plant taxonomy were compared, 418 type specimens were confirmed. There are 239 species belonging to 147 genera in 69 families, including 390 type specimens newly discovered. The quantity, type, species, dominant groups, collectiion location, collection time, and the name type specimen collector were collected and analysed in the herbarium.
The Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC) databases were used to collect RNA sequence information from patients with hepatocellular carcinoma (HCC). The key genes involved in the immune response mechanism to HCC were screened using the non-negative matrix factorization (NMF) clustering method and weighted gene co-expression network analysis (WGCNA). Prognostic gene models were constructed using the least absolute shrinkage and selection operator (LASSO) regression analysis, and biological functions were analyzed using gene set enrichment analysis (GSEA). Subsequently, to assess the immune infiltration and the related functional differences between the patients in two different risk groups , we used single-sample gene set enrichment analysis (ssGSEA). We constructed column line graphs in combination with independent risk factors to predict overall patient survival time using the “RMS” package in R. Finally, preliminary clinical validation was performed using the Human Protein Atlas (HPA) database with real-time quantitative fluorescent PCR (RT-qPCR). In conclusion, we integrated the clinical characteristics of patients based on risk scores to construct a verifiable and reproducible column line chart, providing a reliable reference for the precise treatment of patients in clinical oncology.
This study was conducted to evaluate the effects of an 8-week altitude training on erythropoiesis, iron metabolism, and aerobic capacity in trained rowers. Twenty-eight trained rowers were divided into the altitude training (AT) and sea-level training (ST) groups. During the 8-week training camp, the training plan and load were similar in both groups. VO2peak, red blood cell count (RBC), reticulocyte% (RET%), hemoglobin (Hgb), and concentrations of serum erythroferrone (ERFE), ferritin (FER), and soluble transferrin receptor (sTfR) were measured before and after the 8-week training camp. It found that (1) compared with the pre-value, VO2peak and VO2peak to body mass (RVO2peak) increased significantly after the 8-week training in the AT group. No obvious differences in VO2peak and RVO2peak were observed in the ST group. The changes in VO2peak and RVO2peak between the two groups were significant (+9.41% vs +3.03%, p<0.05; +12.83% vs +0.80%, p<0.01). (2) After the 8-week training, the RBC, Hgb, and hematocrit (HCT) increased in the AT group but no statistical difference in the ST group. Changes in Hgb and HCT between the two groups were significant (+4.95% vs –3.21%, p<0.01; +6.48% vs –1.57%, p<0.01). A significant trend in RBC count change was observed between the two groups (+3.19% vs –3.61%, p=0.061). Compared with the pre-test values, no significant changes in RET% and reticulocyte hemoglobin equivalent (RET-He) were found in either groups after the 8-week training. The AT group showed significantly increased of low fluorescent reticulocyte (LFR) and reticulocyte production index (RPI) and significantly decreased medium fluorescent reticulocyte (MFR) and high fluorescent reticulocyte (HFR). There were no significant differences in RET%, RET-He, LFR, MFR, HFR, and IRF (immature reticulocyte fraction) in both groups. However, changes in RPI between both groups after the training camp was significant (+30.60% vs –4.52%, p<0.05). (3) In the AT group, no remarkable changes in serum ERFE, a significant decrease in serum FER, and an increase in serum sTfR and sTfR/lg(FER) levels were observed after of the 8-week training. In the ST group, there were no statistical changes in serum FER, sTfR, and sTfR/lg(FER) and significantly increased serum ERFE. Changes in serum FER, ERFE, sTfR, and sTfR/lg(FER) levels differed significantly between both groups (+17.99% vs +121.31%, p<0.05; –36.16% vs –2.96%, p<0.05; +82.77% vs –8.87%, p<0.05; +108.40% vs –6.96%, p<0.05). (4) There was a significantly positive association between the change in VO2peak and serum sTfR levels and ratio of sTfR to lg(FER) after the 8-week training. Therefore , eight weeks of AT appears to be more effective than ST in improving the oxygen delivery capacity of the blood and aerobic capacity in trained rowers. In the later stage of the 8-week AT, erythropoiesis remained active. Serum sTfR levels may be important in improving aerobic performance.
