为高效鉴定食用油脂加工厂污水处理过程的气味组成,采用感官检验以臭阈值量化不同处理工序污水的臭味浓度,并采用气相色谱-离子迁移谱法(GC-IMS)对其挥发性化合物进行分析,并对鉴定出的挥发性化合物进行指纹图谱和主成分分析。结果表明:污水经过处理臭阈值明显降低;GC-IMS鉴定出43种化合物,基本均为含氧有机物,包括酮类、醇类、醛类、酯类、酸类及其他类;总体上各处理工序污水挥发性物质总数和臭阈值的变化规律一致;各处理工序挥发性化合物存在一定差异。综上,GC-IMS是分析食用油脂加工厂污水处理过程气味变化的有效方法。 In order to effectively identify odorants in wastewater treatment process in edible oil plant, the odor concentration of wastewater from different treatment processes was quantified by the threshold odor number(TON) through sensory examination, and the volatile organic compounds (VOCs) were identified using gas chromatography-ion mobility spectrometry (GC-IMS) and analysed by fingerprint plot and principal component analysis. The results showed that the TON of wastewater was significantly reduced after treatment. Forty-three compounds were identified by GC-IMS, all of which were basically oxygen-containing organic compounds including ketones, alcohols, aldehydes, esters, acids and others. The change rule of TON of wastewater was overall consistent with volatile compounds among the treatment processes. There was a variation in VOCs′ overallcomposition among the treatment processes. In conclusion, the GC-IMS technique is an efficient method for analyzing the odor variation of wastewater treatment in edible oil plant.

- Abstract
All-trans retinoic acid (ATRA) is able to induce promyelocytic differentiation effectively. However, its role in the process of erythroid differentiation remains unclear. To investigate the role of AT- RA in the process of erythroid differentiation and its epigenetic regulatory mechanism, we established an induced leukemia cell K562 model in this study. Firstly, hemin was used to induce the differentiation of K562 cells into erythroid cells. The results of flow cytometry showed that ATRA affected the lineage changes of cells during erythroid differentiation and blocked the process of cell differentiation. After AT- RA treatment of differentiating cells, the expression level of erythroid differentiation-related genes de- creased. Through chromatin conformational capture (3C), formaldehyde-assisted separation of regulatory elements (FAIRE), chromatin immunoprecipitation (ChIP) techniques, the epigenetic mechanism was explored and it was found that after ATRA treatment of cells, the chromatin accessibility within the B-globin family gene locus decreased, and the frequency of interaction between the locus control region (LCR) and its target gene promoter decreased. The decrease in the chromatin accessibility of the gene locus led to a decrease in the enrichment frequency of erythroid-related transcription factors GATA binding protein 1 (GATA1), LIM domain binding 1 (LDB1), LIM domain only 2 (LMO2), and BHLH transcription factor 1 (TAL1) at the promoter regions of the LCR and the gene locus of the globin family. The above results indicate that the ATRA treatment of differentiating cells leads to a decrease in the chromatin accessibility of erythroid differentiation-related genes, and a more closed chromatin structure hinders the binding of LCR-recruiting transcription factors to the promoter regions of genes, thereby further repressing the expression of B-globin family genes. This dynamic process elucidates the epigenetic mechanism of ATRA in regulating erythroid differentiation. [ABSTRACT FROM AUTHOR]

To analyze the heat tolerance of japonica rice in Liaohe plain rice-growing region, and establish an effective evaluation system of heat tolerance, 20 main varieties of japonica rice suitable for cultivating over this region were selected and planted under simulated temperature increase using the free air temperature increase system. The heat tolerance of different japonica rice varieties was comprehensively evaluated by multivariate statistical analysis methods based on the heat tolerance coefficients of 10 rice trait indicators, the effective panicle number (X1), grain number per spike (X2), seed setting rate (X3), 1000-grain weight (X4), yield (X5), brown rice rate (X6), milled rice rate (X7), protein content (X8), amylose content (X9), and taste value (X10) after harvesting and air-drying the rice. The results showed that the trait indicators except taste value were significantly or extremely reduced under the warming. Correlation analysis based on heat tolerance coefficients revealed different degrees of association between rice trait indicators. Principal component analysis condensed the 10 individual indicators into 4 mutually independent comprehensive indicators. The 4 comprehensive indicators had contribution rates of 34.816%, 19.265%, 15.636%, and 10.605%, respectively, giving a cumulative contribution rate of 80.322%. The comprehensive evaluation values of heat tolerance (Di value) were calculated using the membership function method. The higher the Di value, the stronger the heat tolerance. The heat tolerance of 'Yanjing 456' was the strongest and that of 'Shennong 016' was the worst. The 20 japonica rice varieties were classified into three categories based on their heat tolerance: the first category comprised 7 heat-tolerant varieties, the second category included 6 moderately heat-tolerant varieties, and the third category consisted of 7 heat-sensitive varieties.

Objective: To discuss the effect of cell division cycle protein 20 (CDC20) on the proliferation and cell cycle of endometrial carcinoma (EC) cells, and to clarify its mechanism. Methods: Real-time fluorescence quantitative PCR (RT-qPCR) and Western blotting methods were used to detect the expression levels of CDC20 mRNA and protein in human endometrial stromal T-HESC cell and EC cells (KLE, RL95-2, ZJB-ENC1, and ECC-1 cells). The RL95-2 cells were selected for the subsequent experiments. CDC20 shRNA interference lentivirus was transfected into the RL95-2 cells and the cells were divided into control group, sh-NC group (infected with negative control lentivirus), sh-CDC20 group (infected with CDC20 shRNA interference lentivirus), sh-NC+SM04690 group (infected with negative control lentivirus followed by treatment with 64 nmol·L-1 Wnt/ β -catenin signaling pathway inhibitor SM04690 for 48 h), and sh-CDC20+SM04690 group (infected with CDC20 shRNA interference lentivirus followed by treatment with 64 nmol·L-1 SM04690 for 48 h). RT-qPCR and Western blotting methods were used to detect the expression levels of CDC20 mRNA and proteins in the cells in various groups; CCK-8 method was used to detect the proliferation activities of the RL95-2 cells in various groups; BrdU assay was used to detect the percentages of BrdU positive cells in various groups; flow cytometry was used to detect the percentages of the cells at G2/M stage in various groups; Western blotting method was used to detect the expression levels of β-catenin, oncogene c-Myc, and cyclin D1 proteins in the cells in various groups. Results: Compared with T-HESC cells, the expression levels of CDC20 mRNA and protein in the KLE, RL95-2, ZJB-ENC1, and ECC-1 cells were significantly increased (P<0. 05), and the highest expression levels of CDC20 mRNA and protein were observed in RL95-2 cells. Compared with sh-NC group, the proliferation activities and percentages of the BrdU positive cells in sh-CDC20 group and sh-NC+SM04690 group were significantly decreased (P<0. 05), the percentages of the cells at G2/M phase were significantly increased (P<0. 05), and the expression levels of β -catenin, c-Myc, and cyclin D1 proteins were significantly decreased (P<0. 05). Compared with sh-CDC20 group, the proliferation activity and percentage of BrdU positive cells in sh-CDC20+SM04690 group were significantly decreased (P<0. 05), the percentage of the cells at G2/M phase was significantly increased (P<0. 05), and the expression levels of β-catenin, c-Myc, and cyclin D1 proteins in the cells were significantly decreased (P< 0. 05). Conclusion: CDC20 is highly expressed in the EC cells. Silencing CDC20 may inhibit the cell proliferation by inducing G2/M phase arrest in the RL95-2 cells through the regulation of Wnt/β -catenin signal transduction. [ABSTRACT FROM AUTHOR]

- Abstract
A rare family of complex heterozygotic beta thalassemia was analyzed to explore the relationship between its molecular basis and clinical phenotype. The results of routine genetic testing for thalassemia in the proband showed a homozygous mutation of IVS-Ⅱ-654 (C>T), and her hematologic phenotype was consistent with this genotype. The conventional thalassemia genotype of the proband′s mother was β654M/βN, and the hematologic phenotype was consistent with her genotype. The conventional thalassemia genotype of the elder brother of the proband was βN/βN, and the hematologic phenotype was consistent with his genotype. Notably, the conventional thalassemia genotype of the proband′s father was βN/βN, while his hematologic phenotype did not match with the genotype. Since the genetic results of this family did not conform to the Mendelian inheritance rule, the gene detection of deletion HPFH was conducted additionally in the proband′s father and the proband. When the results of conventional thalassemia gene detection and deletion HPFH gene detection were combined, we found that the genotype of the proband′s father was βSEA-HPFH/βN, and that the genotype of the proband was βSEA-HPFH/β654M. Clinical attention should still be paid to the phenotypic analysis of beta thalassemia. When the phenotype and genotype are inconsistent, it is necessary to re-test or adopt multiple methods to avoid the false negative. [ABSTRACT FROM AUTHOR]

- Abstract
Objective:To investigate the effect of comprehensive pulmonary rehabilitation therapy on pulmonary and motor function in children after pneumonia. Method:Children with improved acute symptoms of community-acquired pneumonia who were hospitalized in PKUFH-Ningxia Women and Children's Hospital from September 2020 to January 2021 were selected and divided into experimental group (n=30) and control group (n=30) according to the treatment intention of patients and parents. Comprehensive pulmonary rehabilitation therapy was provided to the patients in the experimental group. The pulmonary function and motor function of the two groups were assessed prior to intervention and 3 months after intervention. The forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and the ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC), Borg scores and 6min walking test (6MWT) results were recorded and statistically analyzed. Result:After intervention, FEV1/FVC in experimental group was significantly higher than control group (P< 0.05); the FVC, FEV1 and 6MWT of the experimental group were significantly higher than those before intervention (P<0.05). There were significant differences in FVC, FEV1, Borg scores and 6MWT between the experimental group and the control group before and after intervention (P<0.05). Conclusion:Comprehensive pulmonary rehabilitation therapy is helpful to the recovery of pulmonary and motor function in children after community-acquired pneumonia. [ABSTRACT FROM AUTHOR]

Objective To analyze the status quo and related influencing factors of suicidal ideation in maintenance hemodialysis (MHD) patients with uremia. Methods A total of 119 patients with maintenance hemodialysis uremia admitted to the hospital from September 2020 to October 2022 were selected. The Self-rating Idea of Suicide Scale was used to evaluate whether the patients had suicidal ideation. The relevant data of the patients were investigated and the possible influencing factors were included. Logistics regression model was used to analyze the related influencing factors of suicidal ideation. Results Among the 119 patients, 24 (20.17%) had suicidal ideation. Education level of junior high school and below, dialysis time greater than or equal to five years, poor psychological resilience, poor psychological status, and low social support were the influencing factors of suicidal ideation in patients with maintenance hemodialysis uremia, and the difference was statistically significant (OR 1,P<0.05). Conclusion The suicidal ideation of uremic patients with maintenance hemodialysis is higher. Education level, dialysis time, psychological resilience, poor psychological status and social support are the influencing factors of suicidal ideation. [ABSTRACT FROM AUTHOR]
