    Abstract: The freshness of meat products during storage has received unprecedented attention. This study was conducted to investigate the feasibility of a hyperspectral imaging (HSI) technique to determine the freshness state of cooked beef during storage and identify the contaminated areas on the surface of spoiled samples. Hyperspectral images of cooked beef were acquired in the wavelength range of 400–1000 nm and the freshness state of all samples was divided into three classes (freshness, medium freshness, and spoilage) using the measured total viable count (TVC) of bacteria. Fifteen feature spectra variables were extracted by random frog (RF); based on this, six optimal wavelength variables were further selected by correlation analysis (CA). Partial least squares (PLS) and least squares–support vector machine (LS-SVM) classification models were established using different spectral variables. The results indicated that the performance of the RF-CA-LS-SVM classification model with a high overall classification accuracy of 97.14%, the results of sensitivity and specificity in the range of 0.92–1, and the κ coefficient of 0.9575 in the prediction set were obviously superior to other models. Spoiled samples were further obtained using a RF-CA-LS-SVM model, and then six feature images were extracted and further fused by principal component analysis (PCA). A PC3 image was used to segment successfully the contaminated areas from normal areas of cooked beef images using the Otsu threshold algorithm. The results demonstrated that HSI has great potential in classifying the freshness of cooked beef and identifying the contaminated areas. This current study provides a foundational basis for the classification and grading of meat production in further online detection.

    Abstract: Lung cancer remains the most prevalent malignancy and the primary cause of cancer-related deaths worldwide. Unique mutations patterns can be found in lung cancer subtypes, in individual cancers, or within a single tumor, and drugs that target these genetic mutations and signal transduction pathways are often beneficial to patients. In this study, we used the Ion Torrent AmpliSeq Cancer Panel to sequence 737 loci from 45 cancer-related genes and oncogenes to identify genetic mutations in 48 formalin-fixed, paraffin-embedded (FFPE) human lung cancer samples from Chinese patients. We found frequent mutations in EGFR, KRAS, PIK3CA, and TP53 genes. Moreover, we observed that a portion of the lung cancer samples harbored two or more mutations in these key genes. This study demonstrates the feasibility of using the Ion Torrent sequencing to efficiently identify genetic mutations in individual tumors for targeted lung cancer therapy.

    Abstract: The inhibitory effects of nine ionic liquids (ILs) on the catalase activity were investigated using fluorescence, absorption ultraviolet-visible spectroscopy. The interactions of ILs and catalase on the molecular level were studied. The experimental results indicated that ILs could inhibit the catalase activity and their inhibitory abilities depended on their chemical structures. Fluorescence experiments showed that hydrogen bonding played an important role in the interaction process. The inhibitory abilities of ILs on catalase activity could be simply described by their hydrophobicity and hydrogen bonding abilities. Unexpected less inhibitory effects of trifluoromethanesulfonate (TfO − ) might be ascribed to its larger size, which makes it difficult to go through the substrate channel of catalase to the active site.

    Abstract: Serial orders are thought to be spatially represented in working memory: The beginning items in the memorised sequence are associated with the left side of space and the ending items are associated with the right side of space. However, the origin of this ordinal position effect has remained unclear. It was suggested that the direction of serial order–space interaction is related to the reading/writing experience. An alternative hypothesis is that it originates from the “more is right”/“more is up” spatial metaphors we use in daily life. We can adjudicate between the two viewpoints in Chinese readers; they read left-to-right but also have a culturally ancient top-to-bottom reading/writing direction. Thus, the reading/writing viewpoint predicts no or a top-to-bottom effect in serial order–space interaction; whereas the spatial metaphor theory predicts a clear bottom-to-top effect. We designed four experiments to investigate this issue. First, we found a left-to-right ordinal position effect, replicating results obtained in Western populations. However, the vertical ordinal position effect was in the bottom-to-top direction; moreover, it was modulated by hand position (e.g., left hand bottom or up). We suggest that order–space interactions may originate from different sources and are driven by metaphoric comprehension, which itself may ground cognitive processing.

    Abstract: The aims of this study were to understand the prevalence and correlates of syphilis infection among HIV-positive men who have sex with men (MSM) in Shanghai, China. A total of 200 HIV-positive MSM participants were recruited using “snowball” sampling. Participants were tested for syphilis and completed a one-time questionnaire which included demographic characteristics, sexual behaviours with male and female sexual partners, substance use, and use of antiretroviral medications. Prevalence of syphilis infection was 16.5%. Among HIV/syphilis co-infected participants, 63.6% reported having anal sex with male partners and 24.2% did not use condoms consistently during the past six months; 66.7% reported having oral sex with male partners and 51.5% reported unprotected oral sex during the past six months. Factors associated with testing seropositive for syphilis infection included receptive anal sex with a male partner in the past six months (AOR = 12.61, 90% CI = 2.38–66.89), illicit drug use in the past six months (AOR = 11.47, 90% CI = 2.47–53.45), and use of antiretroviral medication (AOR = 4.48, 90% CI = 1.43–14.05). These data indicate a need for “positive prevention” interventions targeting HIV-positive MSM in China.

    Abstract: Visceral pain is common symptom involved in many gastrointestinal disorders such as inflammatory bowel disease. The underlying molecular mechanisms remain elusive. We investigated the molecular mechanisms and the role for voltage gated calcium channel (VGCC) in the pathogenesis in a rat model of 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) induced visceral inflammatory hypersensitivity. Results Using Agilent cDNA arrays, we found 172 genes changed significantly in dorsal root ganglia (DRG) of TNBS treated rats. Among these changed genes, Cav1.2 and Cav2.3 were significantly up-regulated. Then the RT-PCR and Western blot further confirmed the up-regulation of Cav1.2 and Cav2.3. The whole cell patch clamp recording of acutely dissociated colonic specific DRG neurons showed that the peak I Ba density was significantly increased in colonic neurons of TNBS treated rats compared with control rats (−127.82 ± 20.82 pA/pF Vs −91.67 ± 19.02 pA/pF, n = 9, *P 〈 0.05). To distinguish the different type of calcium currents with the corresponding selective channel blockers, we found that L-type (−38.56 ± 3.97 pA/pF Vs −25.75 ± 3.35 pA/pF, n = 9, * P 〈 0.05) and R-type (−13.31 ± 1.36 pA/pF Vs −8.60 ± 1.25 pA/pF, n = 9, * P 〈 0.05) calcium current density were significantly increased in colonic DRG neurons of TNBS treated rats compared with control rats. In addition, pharmacological blockade with L-type antagonist (nimodipine) and R-type antagonist (SNX-482) with intrathecal injection attenuates visceral pain in TNBS induced inflammatory visceral hypersensitivity. Conclusion Cav1.2 and Cav2.3 in colonic primary sensory neurons play an important role in visceral inflammatory hyperalgesia, which maybe the potential therapeutic targets.

    Abstract: Myths have always been a source of inspiration for literary and artistic creation because of their surreal image and idealized vision. To inherit the national culture and the spirit, many films eastern and western take mythical elements as a medium of meaning. So, has the appearance of mythical elements in the films received a positive response from the audience? Based on the films ( n = 919) released in mainland China cinemas from September 2015 to September 2018, this article uses the method of regression analysis and Latent Dirichlet allocation topic model to verify the relationship between mythical elements and audience acceptance. The results show that (a) mythical elements have no significant impact on the box office revenues; (b) and have no positive impact on the film ratings; (c) there is no significant mythical topic in the film reviews of mythical films, which shows that the public in modern society does not show sensitivity to the mythical elements in films. Finally, we discuss the possible causes of the results and put forward corresponding suggestions for the producers of mythical films.

    Abstract: Sang language is an important manifestation of Sang subculture which refers to a cultural trend formed by a large scale of young people born in the 90s and 00s expressing or showing their frustration in various forms on social platforms. In recent years, Sang subculture has evolved from a form of network subculture that initially aroused the inner resonance and self-deprecation of middle school and college students, and has developed into a complete industrial chain formed under the combined effect of the deliberate catering of online media and the active marketing of businesses. Its existence eventually caused the mainstream ideology to be impacted, and the ideals, beliefs and value choices of some students were greatly affected. This article takes Sang language as an anchor, pays attention to the thought changes and behavior characteristics of middle school and college students, as well as the channels and methods of Sang language and subculture communication, and then deeply analyzes its motivation. This article finds that Sang language, due to its inherent unique form of mimicry, reflects the emotional and rational characteristics of youth groups in the process of socialization. In the end, it shows that the timely transformation of mainstream cultural discourse on the Internet, guiding the youth student groups to cultivate and practice positive values, and accurately locating life development goals, should become an important task for school youth cultivation.

    Abstract: Gastric cancer (GC) is a leading cause of cancer-related deaths worldwide. Understanding the molecular mechanisms of GC metastasis is crucial for improving patient survival outcomes. Methods RNA sequencing and analysis were performed on tissue samples from primary and lymph node metastatic lesions of gastric cancer. Differential gene analysis and functional pathway analysis were conducted. Immune infiltrating environment and protein expression levels were evaluated using immunohistochemistry. Cell experiments were conducted to investigate the role of CCL21 in GC metastasis. Results ACTG2, CNN1, DES, MUC6, and PGC were significantly upregulated in primary tumor cells, while CCL21, MS4A1, CR2, CLDN11, and FDCSP were significantly upregulated in metastatic tumor cells. Functional pathway analysis revealed enrichment in pathways related to immune response. CLDN11 and CCL21 were found to play important roles in promoting gastric cancer metastasis. Cell experiments confirmed the role of CCL21 in promoting GC cell growth and metastasis. CCL21 is highly expressed in GC tissues and binds to CCR7, leading to upregulation of CLDN11. This results in GC-lymph node metastasis and abnormal activation of immune cells (B cells and CD4 + T cells). Conclusion Inhibition of CCL21 and CLDN11 proteins may be a promising strategy for treating GC and preventing lymph node metastasis. These findings provide specific molecular markers for early lymph node metastases of GC, which can aid in developing treatment strategies and predicting patient prognosis.
