    Abstract: Background: Mutations in the human breast cancer susceptibility gene 2 (breast cancer 2, BRCA2) increase the risk of breast, ovarian and other cancers. Olaparib, an oral poly[adenosine diphosphate (ADP)-ribose] polymerase (PARP) inhibitor, is usually ... ...

    Abstract Background: Mutations in the human breast cancer susceptibility gene 2 (breast cancer 2, BRCA2) increase the risk of breast, ovarian and other cancers. Olaparib, an oral poly[adenosine diphosphate (ADP)-ribose] polymerase (PARP) inhibitor, is usually prescribed to treat BRCA mutated tumors, especially breast and ovarian cancers. Programmed cell death-1 (PD-1) inhibitors have revolutionized the treatment of lung cancer and many other cancers by destroying the interaction between receptors with ligands in the tumor-immune microenvironment and enabling T cells to recognize and attack cancer cells.
    Case description: In our study, we report a patient with advanced BRCA2 lung squamous cell carcinoma who received platinum-based chemotherapy combined with paclitaxel. Seven months later, the disease progressed. BRCA2 mutations were detected in peripheral blood by next-generation sequencing. After 2 months of treatment with Olaparib combined with Cindilimab, the patient was in partial remission and the progression-free survival (PFS) lasted for 6 months, but the patient developed immune renal damage.
    Conclusions: This study adds to the clinical data for the treatment of BRCA2 mutant non-small cell lung cancer by demonstrating that lung squamous cell carcinoma has a good response to PARP inhibitors. It also serves as a reminder that there may still be some negative effects from targeted superimposed immunotherapy.

    Abstract Background: The protective effect of vitamin C as an antioxidant against asthma in adults remains controversial. This study used an observational study and Mendelian randomization (MR) analysis to investigate the association between adult asthma and serum vitamin C levels.
    Methods: Using information from the National Health and Nutrition Examination Survey (NHANES) 2003-2006, we carried out an observational study. A multivariate logistic regression model was employed to examine the connection between adult asthma and serum vitamin C levels. We used the inverse-variance weighted (IVW) method of MR analysis as the primary method to analyze the causal effect of serum vitamin C levels on asthma in adults.
    Results: A total of 8,504 participants were included in the observational study, including 639 in the asthma group and 7,865 in the non-asthma group. Before sample weighting, serum vitamin C was associated with a reduced risk of asthma in adults (OR = 0.798, 95% CI: 0.673-0.945, P = 0.009). After sample weighting, serum vitamin C was not associated with adult asthma risk (OR = 0.829, 95% CI: 0.660 ~ 1.042, P = 0.104). MR analysis showed no causal relationship between serum vitamin C and adult asthma in either the UK Biobank (OR = 0.957, 95% CI: 0.871 ~ 1.053, P = 0.370) or FinnGen (OR = 0.973, 95% CI: 0.824 ~ 1.149, P = 0.750) cohorts.
    Conclusion: Our study did not support a causal association between serum vitamin C levels and adult asthma risk. The relationship between serum vitamin C and adult asthma requires further research.

    Abstract Crack identification plays a vital role in preventive maintenance strategies during highway pavement maintenance. Therefore, accurate identification of cracks in highway pavement images is the key to highway maintenance work. In this paper, an improved U-Net network adopting multi-scale feature prediction fusion and the improved parallel attention module was put forward to better identify concrete cracks. Multiscale feature prediction fusion combines multiple U-Net features generated by intermediate layers for aggregated prediction, thus using global information from different scales. The improved parallel attention module is used to process the U-Net decoded output of multi-scale feature prediction fusion, which can give more weight to the target region in the image and further capture the global contextual information of the image to improve the recognition accuracy. Improving the bottleneck layer is used to improve the robustness of the model and prevent overfitting. Experiments show that the improved U-Net network in this paper has a significant improvement over the original U-Net network. The performance of the proposed method in this paper was investigated on two publicly available datasets (Crack500 and CFD) and compared with competing methods proposed in the literature. Using the Crack500 dataset, the method in this paper achieved the highest score in precision (89.60%), recall (95.83%), mIOU (83.80%), and F1-score (92.61%). Similarly, for the CFD dataset, the method in this paper achieved high values for precision (93.29%), mIOU (82.07%), recall (86.26%), and F1-score (89.64%). Thus, the method has several advantages for identifying cracks in highway pavements and is an ideal tool for practical work. In future work, identifying more crack types and model light-weighting are the key objectives. Meanwhile, this paper provides a new idea for road crack identification.

    Abstract Skeletal muscle may mutually interact with gastrointestinal disease through metabolic homeostasis and nutritional status and therefore may be a marker for early risk detection. We conducted a prospective cohort analysis including 393,606 participants (mean age 56.0 years, 53.9% female) from the UK Biobank. The exposures were grip strength and skeletal muscle mass (SMM). The primary outcomes were 24 incident gastrointestinal diseases. During a mean follow-up of 12.1 years, we found that one sex-specific SD increase in grip strength and SMM were associated with reduced risk of 16 and 19 gastrointestinal diseases, respectively. For grip strength, the HRs ranged from 0.94 (for ulcerative colitis) to 0.80 (for liver cancers). For SMM, the HRs ranged from 0.92 (for colorectal cancer) to 0.51 (for non-alcoholic fatty liver disease). Our finding suggested that grip strength and SMM might be significant indicators for gastrointestinal diseases risk screen.

    Abstract Polarizer is a key component of the liquid crystal display panel, and the optical properties mainly include transmittance, degree of polarization and chromaticity. Polarizer is made of a multilayer optical film, in which the PVA polarizing film is the core structure for realizing the polarization of the whole polarizer. PVA polarizing film is commonly manufactured through a multi-step craft, including rinsing, dyeing, stretching and correcting. The correction process has a significant impact on the final apparent color and optical properties of the polarizer. In this study, the KI concentration in the correcting tank, ranging from 1% to 3%, was systematically investigated. With the increase in KI concentration, the Raman vibration peak at 160 cm

    Abstract Objective: To elucidate the chemical profile and the pharmacological mechanism by which Jinlingzi powder (, JLZP) treats bile reflux gastritis (BRG).
    Methods: A BRG model was established in rats by oral administration of the model solution. JLZP was orally administered for 35 d. Residual gastric rate and tumor necrosis factor (TNF)-α, interleukin (IL)-6, and gastrin levels in the serum were measured, and stomach tissues were collected for histopathological analysis. We used ultra-high performance liquid chromatography coupled with Q Exactive Focus mass spectrometry to identify the chemical ingredients in JLZP. Then, protein-protein interaction and herb-compound-target networks were constructed to screen potential bioactive compounds and targets. Kyoto Encyclopedia of Genes and Genomes pathway analysis was then performed to elucidate the pathway involved in the JLZP-mediated treatment of BRG. After constructing the core compound-target-pathway interaction network, molecular docking was performed to study the binding free energy of core bioactive compounds and two candidate targets [RAC-alpha serine/threonine-protein kinase (AKT1) and phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform (PIK3CA)].
    Results: JLZP extracts significantly promoted gastric emptying, regulating the release of cytokines (TNF-α and IL-6) and improving gastrin secretion and mucosal repair. Fifty-six compounds were tentatively characterized in JLZP. Moreover, the network pharmacology and molecular docking results showed that alkaloids and flavonoids might be the bioactive compounds in JLZP that treat BRG. JLZP might improve mucosal repair during BRG progression by modulating the phosphatidylinositol-4,5-bisphosphate 3-kinase-protein kinase B, hypoxia inducible factor-1, mitogen-activated protein kinase, forkhead box O, TNF, and IL-17 signaling pathways.
    Conclusions: We elucidated the chemical constituents and the pharmacological mechanism of JLZP in treating BRG and provided a basis for clinical application.

    Abstract Objective: We aimed to evaluate whether individuals with type 2 diabetes (T2D) were at higher risk of developing a wide range of gastrointestinal diseases based on a population-based cohort study.
    Research design and methods: This study included 374,125 participants free of gastrointestinal disorders at baseline; of them, 19,719 (5.27%) with T2D were followed-up by linking to multiple medical records to record gastrointestinal disease diagnoses. Multivariable Cox models were used to estimate the hazard ratios (HRs) and CIs. Logistic models were used to examine the associations between polygenic risk scores (PRS) and clinical gastrointestinal phenotypes.
    Results: During a median follow-up of 12.0 years, we observed the new onset of 15 gastrointestinal diseases. Compared with nondiabetes, participants with T2D had an increased risk of gastritis and duodenitis (HR 1.58, 95% CI 1.51-1.65), peptic ulcer (HR 1.56, 95% CI 1.43-1.71), diverticular disease (HR 1.19, 95% CI 1.14-1.24), pancreatitis (HR 1.45, 95% CI 1.24-1.71), nonalcoholic fatty liver disease (HR 2.46, 95% CI 2.25-2.69), liver cirrhosis (HR 2.92, 95% CI 2.58-3.30), biliary disease (HR 1.18, 95% CI 1.10-1.26), gastrointestinal tract cancers (HR 1.28, 95% CI 1.17-1.40), and hepatobiliary and pancreatic cancer (HR 2.32, 95% CI 2.01-2.67). Positive associations of PRS of T2D with gastritis, duodenitis, and nonalcoholic fatty liver disease were also observed.
    Conclusions: In this large cohort study, we found that T2D was associated with increased risks of a wide range of gastrointestinal outcomes. We suggest the importance of early detection and prevention of gastrointestinal disorders among patients with T2D.
