Summary: Hepatocellular carcinoma (HCC) is a common digestive malignancy and a leading cause of cancer mortality worldwide. Local ablation therapies, such as radiofrequency ablation (RFA) and high-intensity focused ultrasound (HIFU) ablation, have shown effectiveness in treating HCC. However, the molecular mechanisms and HCC recurrence after ablation still need further understanding.

Summary: Hypoxia-inducible factor 1 alpha (HIF-1a) is a transcription factor that regulates the cellular response to hypoxia and is upregulated in all types of solid tumor. Hepatocellular carcinoma (HCC) is a highly vascular and hypoxic tumor, and treatments like TACE and TAE can exacerbate hypoxia in HCC. Hypoxia-activated prodrugs (HAPs) have potential as a targeted treatment for hypoxic HCC, but more research is needed to understand their effects in combination with embolization.

Summary: This article presents the case of a 69-year-old man who developed intractably painful hypertrophic osteoarthropathy (HOA) secondary to lung cancer. Treatment with carboplatin, paclitaxel, and bevacizumab reduced tumor size and plasma vascular endothelial growth factor (VEGF) levels, relieving the patient's leg pain. The immunohistochemical examination showed that lung cancer cells were positive for VEGF, suggesting a potential role of hypoxia-inducible factor-1a in VEGF production. The findings of this study may lead to the development of novel management strategies for painful HOA.

Summary: Globally, chronic hepatitis B virus (HBV) infection is the main cause of hepatocellular carcinoma (HCC). Previous studies have shown elevated levels of hypoxia-inducible factor 1 (HIF1) in HCC and HBV-infected hepatocytes; however, the impact of HIF1 activity on the HBV lifecycle is not well understood. Using liver-derived cell line and ex vivo cultured primary hepatocytes, researchers discovered that HIF1 increases HBV RNA transcript levels, core protein levels, cytoplasmic localization of core protein, and HBV genome replication. Inhibiting the transcription activity of HIF1 blocked its effects on the HBV lifecycle. These findings suggest that HIF1 plays a key role in regulating various stages of the HBV lifecycle and could be a potential therapeutic target for blocking HBV replication and associated diseases.

Summary: This study demonstrates that serum VEGF and VEGF/PLT have high sensitivity and specificity in the early diagnosis of HCC, serving as reliable biomarkers. A VEGF cut-off value of 250 pg/mL has 80% sensitivity and 81.7% specificity, while VEGF/PLT ratio has 77.5% sensitivity and 80% specificity, with a combination increasing diagnostic accuracy to over 95% for HCC.

Summary: Successful treatment of hepatitis C reduces liver inflammation and fibrosis, but patients are still at risk of developing hepatocellular carcinoma. Risk factors for post-SVR HCC include non-Caucasian race, smoking, age over 60, low albumin level, elevated AST/ALT ratio, and low platelet count. AFP may be a promising marker for post-SVR HCC risk.

Summary: A nano-displacement measurement system based on a modified Mach-Zehnder interferometer was proposed and demonstrated theoretically and experimentally, achieving stable and robust interference patterns. By introducing a reflection module and a novel phase-demodulation method, tiny displacements ranging from 50 to 800 nm were successfully measured with a resolution of about 50 pm. This approach may have applications in ultra-high precision displacement sensors as well as temperature, strain, and refractive index sensors.

Summary: This study proposes a simple and reliable method for synthesizing the complex orbit-angular-momentum (OAM) spectrum of hybrid mode in a few-mode fiber. The method utilizes the inverse scattering method based on the genetic algorithm (GA) to optimize the main Fourier components in a specially-selected ring in the intensity distribution of the hybrid mode. A proof-of-concept example demonstrates the successful reconstruction of the power spectrum of a hybrid mode consisting of first- and second-order OAM modes with an accuracy higher than 0.99.

Summary: Orbital-angular-momentum (OAM) beams-based interferometers have attracted significant interest and found various applications in optical precision measurement. In this study, an all-fiber OAM beams-based interferometer was proposed and experimentally demonstrated, utilizing helical long-period fiber gratings (HLPGs) to generate conjugated OAM beams for testing and referencing. The interferograms obtained had polarization independence, robustness, and were particularly suitable for phase-demodulation in the azimuthal angle domain. The proposed interferometer showed high sensitivity and measurement accuracy for temperature and strain, making it suitable for ultra-high precision and sensing measurements.

Summary: A temperature-insensitive torsion and strain sensor based on a helical long-period fiber grating (HLPG) is proposed and demonstrated. The sensor utilizes a second-order HLPG in a thinned four-mode fiber to achieve simultaneous measurement of torsion and strain. The sensor's maximum torsion sensitivity is 665 pm/(rad/m) and maximum strain sensitivity is -5.42 pm/με, which are significantly higher than those of conventional long-period fiber grating (LPG)-based sensors. Additionally, the sensor exhibits a temperature sensitivity of 13.7 pm/°C, which is about 4 times lower than that of conventional LPGs.

Summary: An ultra-wideband orbital-angular-momentum (OAM) mode generator based on a helical long period fiber grating (HLPG) written in a graded-index few-mode fiber (GIFMF) has been proposed and demonstrated. Unlike previous HLPG-based broadband OAM generators, which operated at wavelengths close to the dispersion-turning point (DTP), the GIFMF-based HLPG proposed in this study operates at wavelengths far from the DTP, enabling the production of a ultra-wideband OAM mode generator with high conversion efficiency and flexibility in controlling the central wavelength. A first-order OAM mode generator with a central wavelength of approximately 1510 nm, a bandwidth of approximately 235 nm, and a conversion efficiency larger than 99% (approximately 20.7 dB) has been successfully obtained, marking the first practical demonstration of the GIFMF-based HLPG.

Summary: A miniature temperature-independent curvature sensor was proposed and prepared using a phase-shifted long-period fiber grating fabricated from deeply tapered conventional single-mode fibers. A demonstration of a sensor made from a phase-shifted deeply tapered long-period grating with a length of 3.4 mm and a maximum curvature sensitivity of 12.05 nm/m(-1) was successful. The proposed curvature sensor has the characteristics of temperature independence, high sensitivity, high reliability, miniature size, and low cost, making it potentially useful in structural health monitoring, especially in the medical industry and shape reconstruction.

Summary: In this study, it is demonstrated theoretically and experimentally that the convolutional neural network (CNN) combined with residual blocks and regression methods can accurately and quickly reconstruct the OAM spectrum of hybrid OAM modes, regardless of the consistency of the order indices in both azimuthal and radial directions. The mean errors of recognized parameters for hybrid OAM modes in a 4-mode fiber (4MF) and a 6-mode fiber (6MF) are smaller than 0.003 and 0.008, respectively. This is the first time that all OAM modes in 4MFs or 6MFs can be accurately and quickly recognized using the deep learning method.
