High mobility group box 1 (HMGB1), when released extracellularly, plays a pivotal role in the development of spinal cord synapses and exacerbates autoimmune diseases within the central nervous system. In experimental autoimmune encephalomyelitis (EAE), a condition that models multiple sclerosis, the levels of extracellular HMGB1 and interleukin-33 (IL-33) have been found to be inversely correlated. However, the mechanism by which IL-33 deficiency enhances HMGB1 release during EAE remains elusive. Our study elucidates a potential signaling pathway whereby the absence of IL-33 leads to increased binding of P300/CBP-associated factor with HMGB1 in the nuclei of astrocytes, upregulating HMGB1 acetylation and promoting its release from astrocyte nuclei in the spinal cord of EAE mice. Conversely, the addition of IL-33 counteracts the TNF-α-induced increase in HMGB1 and acetylated HMGB1 levels in primary astrocytes. These findings underscore the potential of IL-33-associated signaling pathways as a therapeutic target for EAE treatment.

There is a large gap between production and demand of plant oil in China, which leads to the heavy reliance on imports. Diacylglycerol acyltransferase (DGAT) and phospholipid: diacylglycerol acyltransferase (PDAT) are two key enzymes responsible for the synthesis of triacylglycerol, thereby affecting the yield and quality of plant oil. This paper comprehensively reviews the research progress in DGAT and PDAT in terms of their biological functions in plant oil synthesis, the molecular mechanisms of regulating plant lipid metabolism, growth, and development under stress, and their roles in driving oil synthesis under the background of synthetic biology. Furthermore, future research and application of DGAT and PDAT are prospected. This review aims to provide a basis for deeply understanding the molecular mechanism of plant oil synthesis and improving the quality and productivity of oil crops by the utilization of DGAT and PDAT genes.

Objective:To explore the relationship between the expression of neuropilin-1 (NRP-1) on Treg cells and its ligands semaphorins-3A (Sema3A) , transforming growth factor-β 1 (TGF-β 1) as well as the balance of type 1 helper T cells (Th 1) and type 2 helper T cells (Th 2) cells. Methods:This study enrolled 62 patients with immune thrombocytopenia (ITP; 33 and 29 newly diagnosed and chronic ITP, respectively) from March 2014 to May 2015. Consequently, 30 healthy people in the same period were selected as the normal control group. The expression of NRP-1 in Treg cells was detected via flow cytometry. The Sema3A, TGF-β 1, IFN-γ, and IL-4 levels in plasma were detected by enzyme-linked immunosorbent assay. The real-time polymerase chain reaction technique was used to detect the mRNA expression levels of NRP-1, Sema3A, and TGF-β 1. The one-way analysis of variance and independent sample t-test was used for comparison between three and two groups, respectively. Correlations among the mRNA expression levels of NRP-1, Sema3A, and TGF-β 1 were assessed via Spearman correlation coefficients. Results:Treg cells in the newly diagnosed ITP group significantly increased compared with those in the chronic ITP and normal control groups. The expression of NRP-1 decreased[ (0.15 ± 0.03) %, (0.33 ± 0.15) %, and (0.46 ± 0.06) %; P<0.01], the plasma Sema3A level increased[ (8.10 ± 1.32) μg/L, (7.41±1.30) μg/L, and (2.88±0.82) μg/L; P<0.01], and the plasma TGF-β 1 level decreased[ (16.50±3.36) μg/L, (35.17±10.26) μg/L, and (41.00±10.02) μg/L; P<0.01]. Moreover, the level of plasma IFN-γ increased[ (17.21+2.80) ng/L, (10.23+1.59) ng/L, and (8.18+3.27) ng/L; P<0.01], and the ratios of Th 1/Th 2 (IFN-γ/IL-4) increased (1.29±0.30, 0.72±0.16, and 0.61±0.27; P<0.01) . The mRNA expressions of NRP-1 and Sema3A in the newly diagnosed ITP and chronic ITP groups were lower than that in the normal control group ( P<0.01) . Consequently, the NRP-1 mRNA expression was positively correlated with Sema3A and TGF-β 1 mRNA expression in the newly diagnosed ITP group. Conclusion:NRP-1 played an essential role in the pathogenesis of ITP.

Objective To explore the difference in efficacy between multiparametric MRI (Mp-MRI) based on prostate imaging reporting and data system version 2 (PI-RADS v2) and abbreviated biparametric MRI (Bp-MRI) in detecting prostate cancer (PCa) and clinically significant prostate cancer (csPCa), and to evaluate the consistency of image interpretation between different readers. Methods The imaging, pathological and clinical data of patients with prostatic Mp-MRI in our hospital from February 2015 to June 2018 were retrospectively analyzed. At the beginning, 250 patients were randomly selected. Two radiologists visually evaluated the images of those patients using two 5-point scoring schemes based on Mp-MRI and Bp-MRI. The remaining cases were independently proceeded by one of the radiologists using two schemes respectively. Weighted Kappa test was used to assess the consistency of the results interpreted by the two radiologists. The receiver operating characteristic (ROC) curve was used to evaluate the efficiency of the two scoring schemes in detecting PCa and csPCa, and with Z test to investigate whether there was any difference in detection efficiency between the two schemes. Results Nine hundred and seventy eight patients were eventually enrolled in the study. The results of the consistency assessment showed that there was good agreement between the two radiologists, whether using Mp-MRI or Bp-MRI, with the weighted Kappa coefficient of 0.800 and 0.812, respectively. The ROC curve analysis showed that the area under the curve (AUC) of PCa detected by Mp-MRI and Bp-MRI was 0.873 and 0.879, respectively, and the AUC of csPCa detected was 0.922 and 0.932, respectively. In addition, there was no statistically significant difference between the AUC of PCa and csPCa detected by the two schemes (P>0.05). Conclusion The Bp-MRI scoring scheme has good stability in the evaluation of benign and malignant prostate, and its detection efficiency of PCa or csPCa is not lower than that of standard Mp-MRI based on PI-RADS v2.

Objective: To investigate the implementation and application effect of 1-hour bundle in the treatment of patients with sepsis. Methods: A convenient sampling method was conducted. 102 patients with sepsis admitted to central intensive care unit (ICU) of Henan Provincial People's Hospital from January 2018 to February 2019 were enrolled. Thirty-five patients with 3-hour and 6-hour bundle from January to September in 2018 were served as the control group, and 67 patients who received 1-hour bundle from October 2018 to February 2019 were served as the observation group. The patients in the control group was treated with 3-hour and 6-hour bundle according to 2012 international guidelines for the diagnosis and treatment of severe sepsis and septic shock; and those in the observation group were treated and nursed according to the 1-hour bundle published by Surviving Sepsis Campaign (SSC) update 2018, and the sepsis cluster treatment medical team was established. The team members were trained in relevant knowledge and discussed the possible obstacles within the team and propose feasible measures. The implementation of the 1-hour bundle in the observation group was recorded. The general data of the patients in both groups including gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), etc. were collected, and the outcome indicators [duration of mechanical ventilation, length of ICU stay, 28-day mortality] were observed. Results: In the observation group, 37 of 67 patients receiving 1-hour bundle met the target, with the overall achievement rate of 55.2% (37/67). Of the 37 eligible patients, 5 patients receiving 1-hour bundle met the target before the training of 1-hour bundle, accounting for only 33.3% (5/15) of the 15 patients who received 1-hour bundle during the same period. With the extension of training time, the achievement rate of sepsis 1-hour bundle was gradually increased [the achievement rate at 1 week and 4 weeks of training was 40.0% (4/10) and 52.4% (11/21), respectively], and increased to 81.0% (17/21) at the end of 12 weeks training. Thirty-seven patients who received 1-hour bundle and met the criteria were enrolled and compared with the control group. There was no significant difference in gender, age, or APACHEⅡ score between the two groups. Compared with the control group, the duration of mechanical ventilation and length of ICU stay of the observation group were significantly shortened (days: 6.15±0.49 vs. 7.24±0.53, days: 8.21±1.49 vs. 9.51±1.92), and the 28-day mortality was decreased significantly [10.8% (4/37) vs. 31.4% (11/35)], with statistically significant differences (all P < 0.05). Conclusions Through teamwork, discussion and improvement, the achievement rate of sepsis 1-hour bundle can be significantly improved. The use of sepsis 1-hour bundle can effectively decrease the duration of mechanical ventilation and length of ICU stay, and reduce the 28-day mortality.
