In order to obtain stable and high-quality austenitic stainless steel welds with high efficiency and low cost, on the basis of combined plasma arc welding(PAW)+tungsten inert gas(TIG) welding, the improved PAW+TIG combined welding process of PAW backing welding with filler wire +TIG pulsed welding to cover weld face was put forward. The S30408 stainless steel with 5 mm thickness was taken as an example for welding test, and the weld was tested by non-destructive test, tensile test and bending test. In addition the implementation factors of improved PAW+TIG combined welding process were summarized. The results showed that the appearance of the weld obtained by the improved PAW+TIG combined welding process was good with no welding deformation, the performance met the requirements of the process, and the welding speed was effectively improved. Applying the welding process to weld stainless steel could extend the life of oils and fats equipment and effectively reduce consumption indicators of engineering projects.

Multimodal sentiment analysis, which extends text-based affective computing to multimodal contexts with visual and speech modalities, is an emerging research area. In the pretrain-finetune paradigm, fine-tuning large pre-trained language models is necessary for good performance on multimodal sentiment analysis. However, fine-tuning large-scale pretrained language models is still prohibitively expensive and insufficient cross-modal interaction also hinders performance. Therefore, a low-rank cross-modal Transformer (LRCMT) is proposed to address these limitations. Inspired by the low-rank parameter updates exhibited by large pretrained models adapting to natural language tasks, LRCMT injects trainable low-rank matrices into frozen layers, significantly reducing trainable parameters while allowing dynamic word representations. Moreover, a cross-modal modules is designed where visual and speech modalities interact before fusing with the text. Extensive experiments on benchmarks demonstrate results on multiple metrics. Ablations validate that low-rank fine-tuning and sufficient cross-modal in-eraction contribute to LRCMT's strong performance. This paper reduces the fine-tuning cost and provides insights into efficient and effective cross-modal fusion. [ABSTRACT FROM AUTHOR]

Objective To understand the levels of serum homocysteine (Hcy), folic acid (FA) and vitamin B12 (VitB12) in pregnant women during different pregnancy periods in Guiyang area and their effects on adverse outcomes of offspring, so as to provide reference for individualized supplementation of FA and VitB12 in pregnant women, prevention of pregnancy complications and fetal birth defects. Methods From January to December 2022, a total of 400 pregnant women with singleton pregnancy were selected from the obstetrics clinic of Guizhou Provincial People's Hospital. Among them, 50 pregnant women with adverse fetal outcomes were selected as the observation group, and 350 pregnant women with normal fetal outcomes were selected as the control group. The observation group and the control group were divided into early pregnancy group, middle pregnancy group and late pregnancy group according to different gestational weeks. Another 100 healthy non-pregnant women of childbearing age who underwent physical examination in the hospital during the same period were selected as the healthy group. The levels of Hcy. FA and VitB12 were detected by enzyme circulation method and chemiluminescence microparticle immunoassay. The changes of serum Hey. FA and VitB12 levels in the three groups were compared. The regression analysis of serum Hcy, FA and VitB12 was carried out by Pearson linear correlation and the related risk factors of adverse fetal outcomes were analyzed by unconditional logistic multiple stepwise regression. Results The levels of serum Hcy, FA and VitB12 in the observation group and the control group were significantly higher than those in the healthy group, and the levels of FA and VitB12were significantly lower than those in the healthy group, the differences were statistically significant( P < 0.05 ) The levels of serum Hey, FA and VitB12 in the observation group were significantly higher than those in the control group, while the levels of FA and Vit B12 were lower than those in the control group, the differences were statistically significant P < 0.05 ) The levels of serum Hcy, FA and VitB12 in pregnant women decreased gradually with the increase of gestational age. Pearson correlation analysis showed that serum Hcy was negatively correlated with FA(r = 0.772, P < 0.05) . Serum Hcy was negatively correlated with VitB12 (r=-0.613,P<0.05). There was a positive correlation between FA and VitB12(r=0.568, P < 0.05 ) The results of unconditional logistic multiple stepwise regression showed that the increase of Hey level, the decrease of FA level and the decrease of VitB12 level were all risk factors for adverse fetal outcomes in pregnant women P < 0.05 ) . Conclusion The levels of serum Hcy, FA and VitB12 in pregnant women are closely related to the occurrence of adverse fetal outcomes. Therefore, the monitoring of these indicators should be strengthened during pregnancy, and intervention measures should be taken once abnormalities are found to reduce the risk of adverse fetal outcomes.

Objective To evaluate the efficacy and incidence of adverse events of photodynamic therapy and loop electrosurgical excision procedure (LEEP) in the treatment of grade 2 cervical intraepithelial neoplasia (CIN2). Methods Forty CIN2 patients were divided into the photodynamic group (20 cases) and LEEP group (20 cases) according to different treatment options. Follow ups were conducted at 3, 6 and 12 months after treatment. High-risk HPV virus (HR-HPV), vaginal microbiota, colposcopy examination and cervical biopsy results were compared between the two groups. Adverse events were recorded. Results There was no significant difference in the composition of lesion reversal, residual lesions and progression after 3 months of treatment between the two groups of patients. After 6 months of treatment, one case relapsed in the photodynamic group, and 12 months after treatment one case relapsed in the LEEP group. Both cases of cervical biopsy pathology were CIN1 grade. There were no significant differences in the conversion rate of HR-HPV and the proportion of normal vaginal microbiota between the two groups of patients at 3, 6, and 12 months after treatment. The proportion of normal vaginal microbiota in the photodynamic group increased sequentially at 12 months after treatment compared to 3 and 6 months after treatment. During the photodynamic treatment, the pain was tolerable in the photodynamic group, while in the LEEP group, the pain was obviously accompanied by bleeding. After treatment, patients in both groups had increased vaginal discharge and lower abdominal pain, but in the LEEP group, local cervical scars formed and one case experienced vaginal bleeding. Conclusion Photodynamic therapy is effective on treating CIN2, with a high negative conversion rate of HR-HPV and almost no damage to the cervix, especially suitable for patients with fertility requirements.

BACKGROUND: Valproic acid, as a histone deacetylase inhibitor, has the ability to promote osteogenic differentiation of cells, but the mechanism is still unclear. OBJECTIVE: To investigate the effect and mechanism of valproic acid on osteogenic differentiation of rat bone marrow mesenchymal stem cells. METHODS: Bone marrow mesenchymal stem cells were isolated from Sprague-Dawley rats and identified by flow cytometry. CCK-8 assay was used to detect the effects of different concentrations of valproic acid on the proliferation of rat bone marrow mesenchymal stem cells, and determine the used concentration of valproic acid. After adding valproic acid, rat bone marrow mesenchymal stem cells were induced to osteogenic differentiation. Alkaline phosphatase staining was performed on day 7 of osteogenic induction culture, and alizarin red staining was performed on day 21 of osteogenic induction culture. Quantitative real-time polymerase chain reaction was used to detect the expression of osteogenesis-related genes and EZH2 on days 3 and 7 of osteogenic induction culture. The protein expression levels of Runt-related transcription factor 2, EZH2 and H3K27me3 were detected by western blot assay on day 5 of osteogenic induction culture. RESULTS AND CONCLUSION: (1) CCK-8 cell proliferation assay showed that bone marrow mesenchymal stem cell proliferation was significantly inhibited by increasing the concentration of valproic acid. (2) The results of alkaline phosphatase staining and alizarin red staining showed that valproic acid could increase the expression of alkaline phosphatase and enhance the ability of bone mineralization. (3) qRT-PCR results showed that valproic acid could increase the expression of osteogenesis-related genes and decrease the expression of EZH2 gene. (4) Western blot assay results showed that valproic acid could increase the expression of Runt-related transcription factor 2 protein and decrease the expression of EZH2 and H3K27me3 protein. (5) It is concluded that valproic acid can promote osteogenic differentiation of rat bone marrow mesenchymal stem cells by down-regulating EZH2 expression. [ABSTRACT FROM AUTHOR]

Style transfer which originates from computer graphics has attracted broader attention in the field of cartography， considerable efforts have been made on cartographic style transfer algorithms and experimental evaluation. However, it also suffers from unclear demarcation of map style, and lack of evaluation of style transfer results. Therefore, firstly, this paper conceptually analyzes the idea of map style and the applicable scenarios of styled maps. Then, we review existing style transfer methods, and categorize available style transfer methods into three groups and compare them with details: Probability statistics-based, con‐ tent-based, and neural network-based. We also discuss three major types of map style transfer methods: Image to map, remote sensing imagery to map, and image to relief shading. And we compare the advantages and disadvantages of style transfer with vector and raster maps. Finally, we envision the future research of map style transfer in terms of three possible research questions: How to select reference images, how to evaluate style transfer results, and how to integrate style transfer into map design process.
