Abstract
OBJECTIVE To explore the plasma metabolomic characteristics of children with transfusion-dependent thalassemia (TDT), and reveal the changes of metabolic pattern in children with TDT. METHODS 23 children with TDT who received regular blood transfusion in Ganzhou Women and Children's Health Care Hospital in 2021 were selected, and 11 healthy children who underwent physical examination during the same period were selected as the control group. The routine indexes between children with TDT and the control group were compared, and then the metabolic composition of plasma samples from children with TDT and the control group was detected by liquid chromatography-mass spectrometry. An OPLS-DA model was established to perform differential analysis on the detected metabolites, and the differential metabolic pathways between the two groups were analyzed based on the differential metabolites. RESULTS The results of routine testing showed that the indexes of ferritin, bilirubin, total bile acid, glucose and triglycerides in children with TDT were significantly higher than those in healthy controls, while hemoglobin and total cholesterol were significantly lower (all P <0.05). However there was no significant difference in lactate dehydrogenase between the two groups (P >0.05). Compared with the control group, 190 differential metabolites (VIP>1) were identified in TDT children. Among them, 168 compounds such as arginine, proline and glycocholic acid were significantly increased, while the other 22 compounds such as myristic acid, eleostearic acid, palmitic acid and linoleic acid were significantly decreased. The metabolic pathway analysis showed that the metabolic impact of TDT on children mainly focused on the upregulation of amino acid metabolism and downregulation of lipid metabolism. CONCLUSION The amino acid and lipid metabolism in children with TDT were significantly changed compared with the healthy control group. This finding is helpful to optimize the treatment choice for children with TDT, and provides a new idea for clinical treatment.

Abstract
The pathogenesis of glioma has remained unclear. In this study, it was found that high expression of the outer dense fibers of sperm tail 3B (ODF3B) in gliomas was positively correlated with the grade of glioma. The higher the grade, the worse the prognosis. ODF3B is closely related to the growth and apoptosis of glioma. In terms of mechanism, ODF3B was found to affect the proliferation and apoptosis of glioma through the JAK1 and JAK2/STAT3 pathways. ODF3B was also found to affect the growth and apoptosis of glioma in vivo. We conclude that ODF3B affects glioma proliferation and apoptosis via the JAK/STAT pathway and is a potential therapeutic target.

Abstract
Objective: To analyze the possible fusion genes with high-throughput transcriptome sequencing in myeloid leukemia patients with normal karyotype. Methods: From May 2017 to January 2019, three cases of myeloid leukemia patients with normal karyotype and negative for common fusion genes from the First Affiliated Hospital of Nanchang University were selected as the research objects. The transcriptome sequencing of bone marrow mononuclear cells was performed by high-throughput gene sequencing technology. Defuse software was used to analyze the gene fusion sequence in the transcriptome data, reverse-transcription polymerase chain reaction (RT-PCR) and Sanger sequencing were used to verify the fusion gene with clear pathological significance. Results: All three patients were diagnosed with myeloid leukemia by clinical manifestations, bone marrow cell morphology, immunology, and histochemical staining. Cytogenetic tests showed normal chromosome karyotypes. Fluorescence in situ hybridization and RT-PCR were used to detect BCR-ABL1, PML-RARA, and other common fusion genes. The results were all negative. Transcriptome sequencing and fusion transcripts analysis revealed that these three patients carried rare fusion genes with clear pathological significance, which included BCR-FGFR1, CPSF6-RARG, and NUP98-RARG, respectively. Conclusion: Transcriptome sequencing can accurately analyze rare but pathologically significant fusion genes that may exist in myeloid leukemia patients with normal karyotypes.

Abstract
Objective: To investigate the possible mechanism of doxycycline inhibiting paraquat-induced pulmonary fibrosis and provide a theoretical basis for its clinical application. Methods: Human lung fibroblast HFL1 cells were selected as the research object in the cell group. Divided into blank group, paraquat group, paraquat+doxycycline group. The expression of TGF-β1, a-SMA, Smad3 and Smad2 protein was detected by ELISA using 40 ml of paraquat 40 umol/L and 3 mg/L of oleic acid 10 mg/L. In the animal group, 120 healthy and clean SD rats were randomly divided into three groups: blank group, paraquat group, paraquat+doxycycline group. The expression of TGF-β1, a-SMA, Smad3 and Smad2 protein in lung tissue of mice at 1 day, 3 days, 7 days, 14 days and 21 days was detected by Elisa method. The expression of TGF-β1, a-SMA, Smad3 and Smad2 protein in lung tissue of 21-day mice was detected by Western Blotting. The pathological changes of lung tissue were observed by HE staining for 1 day, 3 days, 7 days, 14 days and 21 days. Results: In the cell group experiment, the expression of TGF-β1, a-SMA, Smad3 and Smad2 protein increased gradually with paraquat in the paraquat group, and the expression of TGF-β1, a-SMA, Smad3 and Smad2 protein was significantly higher than that in the blank group. The difference was statistically significant (P<0.05) . The expressions of TGF-β1, a-SMA, Smad3 and Smad2 in the paraquat+doxycycline group were significantly lower than those in the paraquat group, but still higher than the blank group, the difference was statistically significant (P<0.05) . Conclusion: Doxycycline inhibits paraquat-induced pulmonary fibrosis by inhibiting the expression of TGF-β1, a-SMA and Smad3, Smad2 proteins.

Abstract
Objective: To compare the predictive value of PSS, APACHEII, SAPSII and SOFA in the prognosis evaluation of acute poisoning. Methods: Clinical data (including PSS score, APACHEII score, SAPSII score and SOFA score, within 24 hours after admission) of 231 acute poisoning patients admitted to the emergency intensive care unit EICU of our hospital from January 2015 to October 2016 was retrospectively analyzed. The patients were divided into the survival group and the dead group according to the 28-day clinical outcomes, comparing the differences of clinical data in each group. To analyze the correlation between PSS score, APACHEII score, SAPSII score and SOFA score in each group, comparing the value and the area under the ROC curve of four scoring systems and evaluate the predictive value of the four scoring systems. Results: Comparing with the survival group and the dead group, PSS score, APACHEII score, SAPSII score and SOFA score were significantly different (P<0.01) . PSS score, APACHEII score, SAPSII score and SOFA score were significantly positive correlation (P<0.01) , the area under the ROC curve (AUC) of the four scoring systems were 0.833, 0.887, 0.843 and 0.843 respectively. The area under the ROC curve (AUC) of APACHEII score was higher than PSS score, SAPSII score and SOFA score, the difference was statistically significant (z=2.351, 2.317, 2.217; P=0.019, 0.021, 0.027) , there was no significant difference in the area (AUC) between the three scoring curves (P>0.05) . The cutoff value (cut-off) , sensitivity, specificity and accuracy rates of PSS score, APACHEII score, SAPSII score and SOFA score were (2.5, 93.1%, 50.9%, 61.5%) , (14.5, 82.8%, 75.7%, 77.48%) , (31.5, 77.6%, 76.90%, 77.08%) , (5.5, 77.60%, 74.60%, 75.35%) . Conclusion: PSS score, APACHEII score, SAPSII score and SOFA score can evaluate the prognosis of patients with acute poisoning, but the APACHEII score is better than the other three scoring systems in evaluating the prognosis for its evaluation ability and accuracy rate.

Abstract
We present results from the first gridless networking field trial with flexible spectrum switching nodes and 620 km of installed fibre links. Signals at 10G, 12.25G, 42.7G, DP-QPSK 40G, DP-QPSK 100G and 555G are generated, successfully transported and switched using flexible, custom spectrum allocation per channel. Spectrum defragmentation is demonstrated using integrated SOA-MZI wavelength converters. Results show error-free end-to-end performance (BER<1e-9) for the OOK channels and good pre-FEC BER performance with sufficient margin to FEC limit for the 40G and 100G coherent channels as well as for the 555G super-channel.

Abstract
An experimental demonstration of gridless spectrum and time switching is presented. We propose and demonstrate a bit-rate and modulation-format independent optical cross-connect architecture, based on gridless spectrum selective switch, 20-ms 3D-MEMS and 10-ns PLZT optical switches, that supports arbitrary spectrum allocation and transparent time multiplexing. The architecture is implemented in a four-node field-fiber-linked testbed to transport continuous RZ and NRZ data channels at 12.5, 42.7 and 170.8 Gb/s, and selectively groom sub-wavelength RZ channels at 42.7 Gb/s. We also showed that the architecture is dynamic and can be reconfigured to meet the routing requirements of the network traffic. Results show error-free operation with an end-to-end power penalty between 0.8 dB and 5 dB for all continuous and sub-wavelength channels.
