Four methanol recovery process flows and main parameters including common single-column distillation, double-effect distillation, single-column heat pump distillation and double-column heat pump distillation were introduced. Taking 40 t/h methanol waste liquid as an example, using Aspen Plus software, the operation energy consumption of the four methanol recovery process routes was simulated and calculated, and their costs were compared and analyzed. The results showed that the cooling energy consumption and heating energy consumption of common single-column distillation, double-effect distillation, double-column heat pump distillation and single-column heat pump distillation decreased in turn. Compared in the comprehensive energy consumption (converted to standard coal) including the electricity consumption of the compressor, the common single-column distillation was the highest, and the comprehensive energy consumption of double-column heat pump distillation, single-column heat pump distillation and double-effect distillation was 34.2%, 353% and 56.5% of that of common single-column distillation respectively. The treatment cost of single-column distillation, double-effect distillation, single-column heat pump distillation and double-column heat pump distillation was 137.8, 78.0, 57.7, 51.2 yuan/t, respectively. Compared with single-column heat pump distillation, the compression ratio of the compressor in double-column heat pump distillation could be greatly reduced, the optional models were more and the technology was mature, and the equipment procurement cost was reduced. In conclusion, double-column heat pump distillation is the most competitive methanol recovery scheme.

The question of how to develop a teaching method suitable for teacher education programs that place particular importance on practice in classroom settings warrants particular concern. Online video-based simulation training (OVST) as a teacher training method holds promise for addressing this issue by allowing learners to increase their opportunities to apply theory-based knowledge in real educational practice, reducing the theory-practice gap. OVST can also be distributed through online learning environments that offer easily repeated large-scale usage at lower cost to a variety of introvert/extravert learners through individual learning trajectories. In this vein, this study aims to introduce a method for developing OVST used to enhance pre-service teacher competence (by immediately intervening during school bullying, or CIISB) and clarifying the efficacy of types of OVST (with and without debriefing) on strengthening pre-service teachers’ CIISB skills. A total of 98 pre-service teachers from four Taiwanese universities and colleges participated in this study that adopted a quasi-experimental design approach. Each of these pre-service teachers was assigned to one of three groups: OVST with debriefing, OVST without debriefing, and an OVST control condition, with a video-based instrument used to map pre-service teachers’ CIISB-related perception, interpretation, and decision-making skills (PID skills). The results of a mixed-model two-way ANOVA analysis indicated that both types of OVST were more effective than the control condition in improving pre-service teachers’ CIISB. OVST with debriefing was also more effective than the OVST without debriefing, suggesting that OVST with debriefing is a promising way to develop pre-service teachers’ clinical competencies, while also offering a valuable resource for teacher education training methods, particularly when conducted under pandemic conditions.

Objective To study the differences of species composition and functional composition of intestinal microorganisms among Tibetan diabetic population, pre-diabetic population and normal population, so as to provide research basis for the prevention and treatment of type 2 diabetes in Tibetan population. Methods Based on the follow-up population of the natural population in southwest China, 111 Tibetan residents in Lhasa were selected according to the inclusion and exclusion criteria, and their demographic and anthropometric information, blood and fecal samples were collected. According to fasting blood glucose and glycosylated hemoglobin levels, they were divided into diabetes group, pre-diabetic group, and normal group. The microflora in feces was determined by macro genomic sequencing, the composition and function differences of intestinal microflora in different populations were compared by bioinformatics methods, and the correlation between phenotype and intestinal microorganisms was analyzed by Spearman rank correlation and linear regression. Results The intestinal abundance of Clostridium pullulans in diabetic population was significantly lower than that in pre-diabetic population and normal population (FDR < 0.050), while Klebsiella pneumoniae was enriched in diabetic population (LDA=3.015, P=0.015). Nucleoside and nucleotide biosynthesis pathways were enriched in diabetics, while pathways related to short-chain fatty acid biosynthesis were enriched in normal people. There was a significant positive correlation between Lactococcus germane and blood glucose (r=0.094). There was a significant negative correlation between Bailey and blood glucose (r=-0.148). Conclusion The intestinal microbiological disorders in Tibetan patients with type 2 diabetes mellitus are characterized by the decrease of beneficial bacteria, the increase of harmful bacteria and the decrease of short-chain fatty acid synthesis-related pathways, which are closely related to the occurrence and development of type 2 diabetes.

In recent years, studies have shown that C/EBP β plays an important role in the occurrence and development of liver cancer, but its specific molecular regulatory mechanism is still unclear. In this study, we analyzed the GEO database and the Kaplan-Meier Plotter database and found that the mRNA expression of C/EBP β was low in hepatocellular carcinoma (HCC) cells (P<0.05), and its low expression was closely related to the prognosis of HCC patients. Furthermore, functional enrichment analysis and TIMER database analysis showed that C/EBP β was mainly involved in biological processes such as cell cycle and DNA transcription, and the expression level of C/EBP β had a strong correlation with the immune infiltration of CD4+ T cells and macrophages (P<0.05). To further investigate the effect of C/EBP β on the proliferation and migration of HCC cells. In the experiment, HCC cells were transiently transfected with C/EBP β siRNA and divided into si-NC group and siC/EBP B group. The mRNA and protein levels of C/EBP β in HCC cells were significantly reduced by qRT-PCR and Western blot (P< 0.05), and MTT detection, plate cloning assay, and 5-ethynyl-2' deoxyuracil nucleoside (Edu) assay confirmed that knockdown of C/EBP β promotes the proliferation of HCC cells (P<0.05); Transwell and scratch assays confirmed that knockdown of C/EBP β promote the migration of HCC cells; Western blot method was used to detect the effect of knockdown of C/EBP β on the expression of migration-related proteins (E-cadherin, N-cadherin) and Wnt/β-catenin signaling pathway proteins. The results showed that knockdown of C/EBP β promotes epithelial-mesenchymal transition (EMT) and activates gene expression of Wnt/β-catenin signaling pathway in HCC cells (P<0.05). In conclusion, C/EBP β was underexpressed in HCC tissues and was positively correlated with the survival prognosis of patients. Knockdown of C/EBP β may promote the proliferation, migration, and epithelial-mesenchymal transformation of HCC cells by activating the Wnt/β-catenin signaling pathway, which provides a basis for the role of C/ EBP β in the occurrence and development of HCC and may be a potential target in the diagnosis and treatment of HCC.

Objective: To establish a a robust and reliable nomogram for predicting the awake outcome of patients with consciousness disorder caused by brain injury at six months based on behavioral scale scores and neuroelectrophysiological techniques. Method: The clinical data (20 predictors) of patients with consciousness disorder who were first diagnosed and hospitalized in the Department of Rehabilitation Medicine of the First Affiliated Hospital of Nanchang University from February 1, 2020 to July1, 2021 were collected retrospectively. Outcome indicators were scored by the Glasgow Outcome Scale-Extended. After multiple imputation of missing values, the LASSO regression method was used to screen the optimized variables, then, the prediction model was constructed by Multivariable Logistic regression analysis, and the nomogram was drawn. Finally, the performance of the model was evaluated by the receiver operating characteristic curve and calibration curves. Result: A total of 144 patients were included in this study according to inclusion and exclusion criteria, of which 79 had a good prognosis and 65 had a poor prognosis. Five predictors were screened out by LASSO logistic regression analysis. Patients with high FOUR score, no pupil dilation, coma time <4 weeks, SEP grade Ⅰ—Ⅱ, muscle tension ≤1+ had a higher probability of good prognosis at 6 months. The AUC of the model is 0.98 (95%CI: 0.97—0.99) >0.75, and the prediction probability of calibration curve is in good agreement with the actual result, indicating that the model has good discrimination and calibration degree. Conclusion: The multi-domain prognostic model based on behavioral scale scores and neuroelectrophysiological techniques and clinical characteristics of patients with consciousness disorders has certain accuracy, which can provide partial reference for predicting the prognosis of patients consciousness disorders in early clinical stage.

[Objective]Carrot plants are prone to early bolting under the influence of low temperature and long sunshine. Exploring SNP loci and candidate genes associated with carrot bolting traits would be beneficial for the breeding of new carrot varieties that are resistant to bolting[Method]This study used 240 carrot germplasm resources as materials to investigate the characteristics of carrot bolt(bolt time, bolt rate, bolt height, and bolt speed)in 2021 and 2022, respectively. Through DNA sequencing and SNP variation detection, high-quality SNP loci obtained from quality control were used for genome-wide association study(GWAS)of bolting related traits.[Result] The bolting traits of 240 carrot germplasm resources demonstrated rich genetic diversity. After analyzing the 2-year data, it was found that there was significant variation in the phenotypes of each trait, with the highest coefficient of variation for bolting rate being 144.32% and 187.89%, and the lowest coefficient of variation for bolting time being 94.89% and 74.63%, respectively. The BLUE value reduced the error caused by the environment, with the lowest coefficient of variation being 22.53%. The correlation analysis results showed that the bolting rate in 2021 was significantly positively correlated with the bolting traits in 2022, and was extremely significantly correlated with the BLUE value. The BLUE value was highly significantly correlated with other traits except for no significant correlation with the bolt time in 2021. Based on the group structure analysis and cluster analysis, the associated groups were divided into four subgroups. Through a 2-year GWAS of the correlation among bolting traits, a total of 344 SNP marker loci were detected that were significantly correlated with bolting traits. Among them, 20 multi-effect loci were significantly correlated with 2 or more bolting traits, and the same loci can be considered as the same SNP. Based on the annotation information, 29 candidate genes related to bolting were screened, of which 14 genes had inhibitory effects on bolting and flowering, and 13 genes that promoted bolting and flowering were mainly related to the photoperiod pathway, vernalization pathway, and flowering integron. The mechanism of action of the other two genes was not yet clear and thus further verification is needed.[Conclusion] Multiple SNP loci associated with bolting traits were obtained by GWAS analysis, and related candidate genes were identified.

Objective To evaluate the changes in surgical approaches and treatment strategies for foramen magnum (FM) meningiomas located in the anterior or anterolateral aspect of the medulla oblongata. Methods The clinical data of 72 patients suffering a meningioma attached to dura of the anterior or anterolateral FM rim admitted to General Hospital of the People's Liberation Army from January 2007 to January 2022 were analyzed retrospectively. The relevant literature were reviewed. Results Tumor removal was accomplished via a posterolateral suboccipital retrocondylar approach in all patients. Total resection was achieved in 65 patients (90%). 7 patients (10%) of subtotal resection underwent cyberknife radiosurgery. 12 cases (17%) had hypoglossal nerve dysfunction, and 8 improved within 3 months after surgery. 18 cases (25%) experienced hoarseness and/or difficulty swallowing, 15 improved within 3 months after surgery, and 1 underwent tracheotomy due to posterior cranial nerve paralysis. 1 suffered from hemiplegia due to anterior spinal artery injury. There were no surgical deaths. No tumor recurrence was observed after a mean follow-up period of 3 years (range, 12-60 months) with clinical and MRI examination. Conclusions Microsurgery via retrocondylar approach to remove anterior and anterolateral FM meningiomas can not only meet the needs of surgical exposure, but also avoid excessive bone grinding, achieving good total resection rate, low complications, and long-term satisfactory therapeutic effect. The occurrence of serious complications such as postoperative hemiplegia is mainly due to intraoperative vascular damage. [ABSTRACT FROM AUTHOR]

Research on bryophytes was conducted to understand the composition and characteristics of the liverwort flora in the typical area of Motuo. A new list of liverworts in the typical area of Motuo was prepared using field investigation, specimen collection, identification, literature review, and data statistical analysis. The liverworts in typical area of Motuo were divided using the seed plant method and compared with those in 8 areas with similar geographical locations or climate types. Based on the identification results of 1 363 collected specimens, 38 families, 68 genera, and 214 species of liverworts (including four varieties and seven subspecies) were identified in typical area of Motuo. There are 13 flora types of liverworts in the typical regions, the top three being East Asia (25%), Tropical Asia (23.56%), and North temperate (19.23%), and 13.46% of these species are endemic to China. The flora types of the liverworts in the flora types of Motuo were rich and diverse. The proportion of floristic components of tropical and temperate nature was relatively high and similar. It was closely related to the typical liverwort flora of East Asia and had the characteristics of Chinese liverwort flora. The number of liverwort flora types in typical area of Motuo fluctuated with elevation and showed at least two peaks, which was closely related to species richness. Among the 9 study regions, the species richness of typical regions of Motuo was second only to that of the Qinling Mountain. The genus and species compositions were the closest to Qizimei and Sygera Mountains, respectively. According to the principle component analysis of tropical nature, temperate nature, East Asia, and endemic to China, the relationship with Qizimei Mountain was the closest. [ABSTRACT FROM AUTHOR]

In order to explore the dynamic response law of the road surface driven by the explosion of buried gas pipelines, the ANSYS software was used to simulate the explosion process of natural gas pipelines. The over-pressure peak values at different points of the road were obtained by changing the three main factors of pipeline: burial depth, wall thickness, and laying angle. The human and material safety index was obtained by comparing it with the safety evaluation criteria. The research results show that the buried depth of pipelines has a significant impact on the peak value of road over-pressure. Under a single variable change, the peak value of road over)pressure decreases as the buried depth increases. When the buried depth exceeds 5 m, the explosion shock wave is not sufficient to damage the road surface and have an impact on people and buildings; When the pipe wall thickness changes, the peak value of road over-pressure presents an " increase decrease" trend. When the wall thickness is 15 mm, the peak value of over-pressure reaches its peak. When the wall thickness reaches 20 mm, the explosion shock wave is not sufficient to cause damage to people and objects. When the included angle of pipeline laying changes, the peak value of road over-pressure presents a trend of “ decreasing” . There is no safe laying angle directly above the explosion point of the pipeline. When the laying angle is 60°, the rest of the road is within the safe range. [ABSTRACT FROM AUTHOR]

Potato production in China is often affected by viral diseases, and aphids are important vectors for the transmission of potato viral diseases. From July to August 2021 and 2022, aphids in potato fields were collected in Siziwang Banner, Wulanchabu City, Inner Mongolia Autonomous Region using yellow trap and yellow plate, and the species identification and community structure analysis of the collected samples were carried out. Eighteen genera and 24 species of aphids in the local potato fields were identified. Among them, Hyalopterus pruni, Aphis gossypii, Myzus persicae, A. craccivora, Acyrthosiphon kondoi, Macropodaphis paradoxa, Sitobion miscanthi and Rhopalosiphum padi were the dominant species. According to the analysis of the diversity index, richness index and evenness index of the aphid community, the relative number of dominant populations changed little with time, which indicates that the composition of the aphid community in the potato field in this region is relatively stable. The experimental results would lay a research foundation for the monitor and control of aphids in local potato fields. [ABSTRACT FROM AUTHOR]
