Objective To study the application value of PET/CT radiomics combined with long noncoding RNA DiGeorge syndrome critical region gene 5 (LncRNA-DGCR5) in the precision medicine of non-small cell lung cancer (NSCLC). Methods A total of 106 NSCLC patients received PET/CT examination and chemoradiotherapy, and their efficacy was evaluated according to the Evaluation Criteria for Solid Tumor Efficacy after Treatment (RECIST). Patients with complete remission and partial remission were included in the response group (58 cases), and patients with stable or progressive disease were included in the non-response group (48 cases). Image texture parameters of PET/CT including SUVmax (maximum standard value), mean value, variance, kurtosis, skewness, contrast, entropy and energy were compared between groups. Real-time fluorescence quantitative PCR was used to detect LncRNA-DGCR5 expression in peripheral blood. Receiver operating characteristic curve (ROC) was constructed to analyze the predictive value of each index to the therapeutic efficacy of NSCLC patients. Results The SUVmax value, entropy and expression of LncRNA-DGCR5 were significantly lower in the response group than those in the non-response group (P＜0.05), and the energy was significantly higher in the response group than that in the non-response group (P＜0.05). There were no significant differences in the other parameters between the two groups. Patients were divided into the low LncRNA-DGCR5 expression group (51 cases) and the high LncRNA-DGCr5 expression group (55 cases) according to the mean expression of LncRNA-DGCR5 (2.01) as the critical value. Compared with the low LncRNA-DGCR5 expression group, the PET/CT image texture parameters of SUVmax and entropy were significantly increased in the high LncRNA-DGCR5 expression group, and the energy was significantly decreased (P＜0.05). ROC curve construction showed that the AUCs of SUVmax value, entropy, energy and LncRNA-DGCR5 expression on predicting the treatment efficacy of patients with NSCLC were 0.897, 0.851, 0.795 and 0.949 respectively, and the AUC of combined prediction was the highest at 0.998. Conclusion PET/CT radiomics combined with LncRNA-DGCR5 is helpful to predict the treatment efficacy of patients with NSCLC, thus providing the guidance for precision medicine of NSCLC.

Prostate cancer (PCa) is most common among American and European elder males. Despite having the initial effectiveness of radical surgery and androgen deprivation therapy at the preliminary stage, prostate cancer eventually develops into castration-resistant prostate cancer (CRPC), which results in a poor prognosis. In recent years, base-PD-1 inhibitor pembrolizumab has been successfully applied in treating multiple solid tumors, which also has achieved primary efficacy in treating CRPC. This paper summarizes the current status and existing problems of pembrolizumab in the clinical trials of CRPC. [ABSTRACT FROM AUTHOR]

Assured deletion of cloud data is a key issue to be solved in the field of cloud storage security. Existing schemes generally have the drawbacks of over-reliance on key destruction, lack of strong non-separability of ciphertext, excessive encryption and decryption overhead and so on. To solve these problems, by combining AONT conversion with block cipher, a cloud data assured deletion scheme is proposed, which achieves strong non-separability of ciphertext by confusing the original data itself. Theoretical analysis and experimental results show that destroying any piece of cipher data will result in unrecoverable original data in this scheme, thus getting rid of over-reliance on key destruction, which achieves the expected goal of trusted deletion. At the same time, by introducing data block shuffling and reducing the number of cryptographic operations, the ability of anti-ciphertext analysis is improved and the computing overhead is significantly reduced. This scheme has obvious performance advantages compared with existing schemes. [ABSTRACT FROM AUTHOR]

(1) Background Forestry ecological security has become an important barrier for a country or region, and plays an important role in the sustainable development of economy, society and nature of a country or region. Based on Lotka-Volterra model, the forest ecological security in Southwest China is evaluated to provide the basis for formulating effective forestry ecological security policy. (2) Methods The forestry ecological security evaluation system was constructed from three aspects of forestry industry, forest ecology and environmental capacity, and the forestry ecological security status and warning level in Southwest China were evaluated by combining the forestry Lotka-Volterra model, then the coordination degree model was used to analyze the coordination between forestry industry and forest ecosystem, and at last the obstacle factors affecting the forestry ecological security were diagnosed by combining with the obstacle degree model. (3) Results First, from 2006 to 2020, the forestry ecological security in Southwest China experienced a dynamic change process of hazard-high risk-risk-rehabilitation-health. On the whole, the forestry ecological security is developing towards green security, the main reason is that the forest resources in Southwest China are more abundant, the ratio of natural forest area, forest stock and forest coverage rate are higher. However, the forestry ecological security is still in the early warning state, the main reason is that the regional competitive advantage of Southwest China is relatively weak, and the ability to transform ecological benefits into economic benefits is weak. Second, the coordination degree between forestry industry and forest ecology in Southwest China is increasing, but the value is less than 0.3. At the same time, the level of forest ecology was higher than that of forestry industry in Southwest China from 2006 to 2010, and the level of forestry industry was higher than that of forest ecology in Southwest China from 2011 to 2020, indicating that the forestry industry and forest ecosystem in Southwest China are not in a harmonious development state. Third, among the main obstacle factors, the highest frequency was the gross forestry output value and the total forestry investment, both of which were 20.0%. It shows that the development of forestry industry and human response to forestry industry will affect the result of forestry ecological security. Three of the six obstacle factors belong to the human response level, and the obstacle factors mainly concentrate in forestry industry and environmental capacity indicator level. Therefore, the result of forestry ecological security is closely related to human response in the process of ecological protection. (4) Conclusions and Discussions-First, the forestry ecological security in Southwest China presents a good trend of development, but it is still in the early warning state. Second, the forestry industry and forest ecosystem in Southwest China are in a state of imbalance. Third, human response has an important impact on the forestry ecological security in Southwest China. Based on the above analysis, the following policy suggestions are proposed: First, develop the tertiary industry of forestry while developing the secondary industry of forestry, explore more diversified ways of industrial development and transform the advantages of abundant natural resources into economic advantages. Second, develop forestry science and technology so as to increase the rate of forest pests control, reduce the areas affected by forest fires, and control the increased areas of soil erosion more effectively. Third, implement the concept of "Two Mountains", and increase pollution control, forestry investment and financial support. Fourth, increase the total afforestation area to play the role of ecological barrier in Southwest China while developing the forestry industry, and protect forest ecology so that forestry industry and forest ecological construction can develop harmoniously.

Galectin-8 is a member of the galectin family, and binds with β-galactoside by specific recognition with many biological functions. The present study was conducted to investigate Galectin-8 sequence characterization, its tissue distribution, and the effect of dietary ferulic acid（FA) supplementation on the Galectin-8 gene expression in hybrid grouper（Epinephelus fuscoguttatus ♀ × E. polyphekadion ♂). The technology of rapid amplification of cDNA ends（RACE）was utilized to obtain the full length（1 368 bp）of hybrid grouper Galectin- 8 cDNA for the first time. The cDNA was composed of 5' untranslated region（5' UTR）（16 bp), 3' UTR（394 bp), and open reading frame（ORF）of 960 bp that encoded 319 amino acids. The amino acid sequence of galectin-8 possessed two carbohydrate recognition domains （CRDs）at N- and C- terminus composed of 136 and 133 amino acids, respectively, which were connected by a linker peptide of 36 amino acids and contained two conserved H-NPR and WG-EE motifs. Homology and phylogenetic tree analysis indicated that hybrid grouper Galectin- 8 demonstrated the highest identity（98.43%）with E. fuscoguttatus, and was clustered with other teleosts. Based on RT-qPCR, tissue distribution analysis revealed that Galectin-8 showed the highest expressions in the spleen, followed by mid kidney, heart, intestine, liver, head kidney, and gill, yet the trace expression in the brain, stomach, skin, and muscle. Moreover, dietary FA supplementation at level of 40-320 mg/kg considerably up-regulated the Galectin-8 transcriptional level of the intestine, liver, head kidney, and spleen in hybrid grouper（P < 0.05), which suggested that FA served as an immunostimulant to improve its innate immunity. Nevertheless, Galectin-8 immune functions of the hybrid grouper are unclear, and therefore further studies are needed to illustrate its role in defense against pathogen invasion.

As the main part of the trench cable gallery, the work well has many functions, such as cable laying, setting cable intermediate joint and cable lead-out. In order to improve the field construction efficiency, most of the work wells in the project are prefabricated by processing plants and assembled on site. The form of split has a great influence on the overall stiffness and bearing capacity of the work well, and unreasonable form of joint will cause the overall mechanical performance of the structure to decrease. Finite element models of three common channel and gallery work wells, i.e. one-type, T-type and cross-type, were established to analyze the bending and shear behavior of longitudinal and transverse joints respectively, and to compare the internal force and deformation with the integral cast-in-situ work well. The calculation results show that the stiffness under longitudinal joints of I-shaped, T-shaped and cross shaped work wells decrease by 48%, 51% and 44% respectively. The bending stiffness under transverse slits decreases by 34%, 32% and 26% respectively. The research results can provide reference for the sectional assembly design and engineering application of the prefabricated trench gallery work well. [ABSTRACT FROM AUTHOR]

In this experiment, 48 5-week-old mice were exposed to arsenic and riboflavin through drinking water. The control group, the arsenic treatment group (20 mg/L As2O3), the riboflavin treatment group (20 mg/L VB2), the arsenic and riboflavin combined group (20 mg/L As2O3+20 mg/L VB2) were set up to explore the alleviating effect of riboflavin on tissue injury caused by arsenic. The results showed that arsenic treatment caused the heart muscle fiber septa widening, fiber bundles bending, myocardial nucleus shedding, alveolar wall thickening and alveolar cavity shrinking compared with the control group. The number of cerebral cortex cells was significantly reduced and disordered, and the nuclei were dissolved and broken. The addition of riboflavin significantly reduced the damage of arsenic to heart, lung and brain. Therefore, this study confirmed that riboflavin intervention has a significant alleviating effect on the structural damage of heart, lung and brain caused by arsenic, it provides new ideas for the toxicological mechanism and prevention of arsenic poisoning.

Cold stress of livestock easily occurs in open sheds of cold areas during winter, due mainly to the relatively low thermal insulation under the low temperature conditions. As such, cold drinking water can further deteriorate the health and growth of young livestock. The objective of this study was to investigate the effect of drinking warm water in winter on the health and growth performance of weaned rabbits. A total of 180 weaned rabbits (47 days of age) with similar body weight (initial body weight 1.2±0.1 kg) were randomly assigned to two groups, either warm water (WW) or cold water (CW) (90 rabbits in each group). An electrical heating wire was also used to heat the warm water, where the water pipe was covered with insulated foam coating. A thermostatic controller was selected to remain at a constant temperature (35.5 ± 1.1 ◦C) during the experiment. The cold water was prepared at (5.8 ± 2.3)◦C without heating. A 48-day test was carried out to measure various indicators. The results showed that: 1) The indoor average air temperature was (8.9±3.2)℃ during the experiment. The average daily weight gain of rabbits in warm water group was significantly higher than that in cold water group during 47-58 days and 47-94 days, respectively, by 15.11 kg/d and 1.94 kg/d (P<0.05).. 2) The feed-weight ratio of rabbits was significantly lower in the warm water group than that in the cold water group during 47～58 days (18.2%) (P < 0.05). But there was no significant difference during the rest. In addition, the risk of diarrhea in rabbits drinking warm water was significantly reduced by 25.6% during 47～94 days (P < 0.05), compared with the cold water group. The expressions of thyroid hormone receptor α and β (THR α and β) in jejunum were significantly down-regulated on 70 days in rabbits drinking warm water (P < 0.05). 3) The contents of immunoglobulin A (IgA) and total protein (TP) in serum increased significantly for the rabbits drinking warm water, with the increase of age, especially on 82 days (P < 0.05). Moreover, the abundance of Roseburia increased in the cecum of rabbits on 82 days in the warm water group, relating to nutrient digestion and absorption, indicating 6.9 times higher than that of 58-day old rabbits (P < 0.05). Consequently, the constant temperature drinking system in the open sheds in winter can be expected to improve the immunity, intestinal digestion, and absorption capacity, thereby promoting the growth and health of weaned rabbits. The finding can provide theoretical support to improve the survival rate and production efficiency of weaned rabbits in open houses in cold areas. [ABSTRACT FROM AUTHOR]
