Brain-computer interface (BCI) has high application value in the field of healthcare. However, in practical clinical applications, convenience and system performance should be considered in the use of BCI. Wearable BCIs are generally with high convenience, but their performance in real-life scenario needs to be evaluated. This study proposed a wearable steady-state visual evoked potential (SSVEP)-based BCI system equipped with a small-sized electroencephalogram (EEG) collector and a high-performance training-free decoding algorithm. Ten healthy subjects participated in the test of BCI system under simplified experimental preparation. The results showed that the average classification accuracy of this BCI was 94.10% for 40 targets, and there was no significant difference compared to the dataset collected under the laboratory condition. The system achieved a maximum information transfer rate (ITR) of 115.25 bit/min with 8-channel signal and 98.49 bit/min with 4-channel signal, indicating that the 4-channel solution can be used as an option for the few-channel BCI. Overall, this wearable SSVEP-BCI can achieve good performance in real-life scenario, which helps to promote BCI technology in clinical practice.

Saponins associated with Panax notoginseng (P. notoginseng) demonstrate significant therapeutic efficacy across multiple diseases. However, certain high-yield saponins face limited clinical applications due to their reduced pharmacological efficacy. This study synthesized and evaluated 36 saponin-1,2,3-triazole derivatives of ginsenosides Rg1/Rb1 and notoginsenoside R1 for anti-adipogenesis activity in vitro. The research revealed that the ginsenosides Rg1-1,2,3-triazole derivative a17 demonstrates superior adipogenesis inhibitory effects. Structure-activity relationships (SARs) analysis indicates that incorporating an amidyl-substituted 1,2,3-triazole into the saponin side chain via Click reaction enhances anti-adipogenesis activity. Additionally, several other derivatives exhibit general adipogenesis inhibition. Compound a17 demonstrated enhanced potency compared to the parent ginsenoside Rg1. Mechanistic investigations revealed that a17 exhibits dose-dependent inhibition of adipogenesis in vitro, accompanied by decreased expression of preadipocytes. Peroxisome proliferator-activated receptor γ (PPARγ), fatty acid synthase (FAS), and fatty acid binding protein 4 (FABP4) adipogenesis regulators. These findings establish the ginsenoside Rg1-1,2,3-triazole derivative a17 as a promising adipocyte differentiation inhibitor and potential therapeutic agent for obesity and associated metabolic disorders. This research provides a foundation for developing effective therapeutic approaches for various metabolic syndromes.

4.Value of local treatment combined with systemic therapy in conversion therapy for hepatocellular carcinoma
Journal of Clinical Hepatology 2024;40(9):1732-1737
Hepatocellular carcinoma(HCC)is one of the most common malignant tumors in clinical practice.Due to the lack of typical clinical manifestations in the early stage,most patients in China are in the advanced stage at the time of confirmed diagnosis and thus lose the opportunity for surgical resection,which leads to a poor prognosis.Therefore,it is necessary to explore related therapies for converting unresectable HCC into resectable HCC.In recent years,the improvement in local therapy such as transarterial interventional therapies and radiation therapy technology,together with the clinical application of new targeted therapies and immune checkpoint inhibitors,has brought new opportunities and challenges in the conversion therapy for advanced HCC,and local therapy combined with systemic therapy may have a good synergistic effect,improve the conversion rate of surgery.This article investigates the value of local therapy combined with systemic therapy in the conversion therapy for HCC,in order to provide a basis for the clinical treatment of unresectable HCC.

Since 2019, severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has been widespread in the world, causing about 770 million infecting and 6.9 million deaths. Vaccines against SARS-CoV-2 infection have become the main way to prevent the severe SARS-CoV-2. The use of SARS-CoV-2 vaccine has substantial protection against the serious consequences of SARS-CoV-2 infection, but multiple systemic adverse reactions can occur after the use of SARS-CoV-2 vaccine. More and more studies have shown that SARS-CoV-2 vaccine caused lesions of ocular conjunctiva, cornea, sclera, uvea, retina and optic nerve tissue and resulted in damage to visual function. In this paper, the classification and characteristics of SARS-CoV-2 vaccines and related studies on ocular tissue lesions were reviewed, hoping to better understand the ocular adverse reactions of SARS-CoV-2 vaccine and provide some theoretical guidance for the prevention and treatment of ocular tissue damage caused by SARS-COV-2 vaccine.
