Cancer immunotherapy has garnered promise in tumor progression, invasion, and metastasis through establishing durable and memorable immunological activity. However, low response rates, adverse side effects, and high costs compromise the additional benefits for patients treated with current chemical and biological agents. Chinese herbal medicines (CHMs) are a potential treasure trove of natural medicines and are gaining momentum in cancer immunomodulation with multi-component, multi-target, and multi-pathway characteristics. The active ingredient extracted from CHMs benefit generalized patients through modulating immune response mechanisms. Additionally, the introduction of nanotechnology has greatly improved the pharmacological qualities of active ingredients through increasing the hydrophilicity, stability, permeability, and targeting characteristics, further enhancing anti-cancer immunity. In this review, we summarize the mechanism of active ingredients for cancer immunomodulation, highlight nano-formulated deliveries of active ingredients for cancer immunotherapy, and provide insights into the future applications in the emerging field of nano-formulated active ingredients of CHMs.

The controllable and safe hydrogen storage technologies are widely recognized as the main bottleneck for the accomplishment of sustainable hydrogen energy.Ammonia borane(AB)has regarded as a competitive candidate for chemical hydrogen storage.However,developing efficient yet high-performance catalysts towards hydrogen evolution from AB hydrolysis remains an enormous challenge.Herein,cobalt phosphide nanosheets are synthesized by a facile salt-assisted along with low-temperature phosphidation strategy for simultaneously modulating its morphology and electronic structure,and function as hydrogen evolution photocatalysts.Impressively,the Co_(2)P nanosheets display extraordinary performance with a record high turnover frequency of 44.9 min^(-1),outperforming most of the noble-metal-free catalysts reported to date.This remarkable performance is attributed to its desired nanosheets structure,featuring with high specific surface area,abundant exposed active sites,and short charge diffusion paths.Our findings provide a novel strategy for regulating metal phosphides with desired phase structure and morphology for energy-related applications and beyond.

Biophotons Contribute to Retinal Dark Noise

Neuroscience Bulletin 2016年第3期32卷 246-252页

The discovery of dark noise in retinal photoreceptors resulted in a long-lasting controversy over its origin and the underlying mechanisms.Here,we used a novel ultra-weak biophoton imaging system（UBIS） to detect biophotonic activity（emission） under dark conditions in rat and bullfrog（Rana catesbeiana） retinas in vitro.We found a significant temperature-dependent increase in biophotonic activity that was completely blocked either by removing intracellular and extracellular Ca^（2＋）together or inhibiting phosphodiesterase 6.These findings suggest that the photon-like component of discrete dark noise may not be caused by a direct contribution of the thermal activation of rhodopsin,but rather by an indirect thermal induction of biophotonic activity,which then activates the retinal chromophore of rhodopsin.Therefore,this study suggests a possible solution regarding the thermal activation energy barrier for discrete dark noise,which has been debated for almost half a century.

Why Are There So Many Puzzles in Fighting against COVID-19 Pandemic?

引用

Natural Science 2022年第10期14卷 424-433页

作者： jiapei dai Wuhan Institute for Neuroscience and Neuroengineering South-Central Minzu University Wuhan China

The novel coronavirus (SARS-CoV-2) and its variety that causes coronavirus disease 2019 (COVID-19) have had a great impact on human health and society since it was epidemic in 2019. The traditional immunological theories believe that human body resists the invasion of exogenous substances, such as different kinds of pathogenic microorganisms, through natural immunity and acquired immunity. We have greatly understood the underlying mechanisms of these two kinds of immunities, which are achieved through cellular and humoral immunity. Immune cells mainly include B and T cells. B cells produce specific antibodies and participate in the humoral immune response, while T cells have more extensive immune effects related to the cellular immune response. Therefore, such traditional immunological theories allow us habitually believe that the human body can resist the attack of virus as long as we have established the so-called normal cellular and humoral immune functions, however, in fact, this is not the case. The traditional ideas make us ignore the most critical, but simple and important defense system in our body to fight against the attack of foreign microorganisms, and that is the intracellular potassium ions (K+) and extracellular sodium ions (Na+), in particular, the intracellular potassium ions, called “K+/Na+ natural immune system”. The abnormality of this system, in particular, the intracellular relative deficiency of potassium ions, may have a very important relationship with the susceptibility and pathogenesis of the body to viral infection, and could explain a series of confusing phenomena that appeared during SARS-CoV-2 pandemic and provide new ideas for the prevention and treatment of COVID-19.

The Core Mechanism of Traditional Medicine Is the Rational and Effective Use of Potassium Ions

引用

Natural Science 2022年第11期14卷 483-491页

作者： jiapei dai Wuhan Institute for Neuroscience and Neuroengineering South-Central Minzu University Wuhan China

The use of traditional medicines including natural drugs, especially traditional Chinese medicine (TCM), plays an important role in the prevention and treatment of human diseases;however, so far, the mechanism of its prevention, health care and treatment of diseases is unclear. Here, I propose that the core mechanism of traditional medicines is to correct the relative deficiency of potassium ions in body and at the same time improve the utilization efficiency of potassium ions, so as to improve or restore cell functions in organs and tissues, and let the body return to a normal state. In order to achieve such a core goal, the therapeutic effect of natural drugs has an important relationship with the rational matching of prescriptions and the quality of drugs, with particular emphasis on the concentrations and quantum energy levels of potassium ions or their compounds in the formula. The understanding of the core effect of potassium in natural drugs has a specific and important guiding role for the artificial cultivation and rational use of natural drugs. Moreover, these ideas may also provide an important theoretical basis for the development of modern agriculture and medicine, and the rational and comprehensive utilization of potassium resources.

The Relative Deficiency of Potassium Ions in Nerve Cells Causes Abnormal Functions and Neurological and Mental Diseases

引用

Natural Science 2022年第10期14卷 441-447页

作者： jiapei dai Wuhan Institute for Neuroscience and Neuroengineering South-Central Minzu University Wuhan China

The difference of intracellular potassium (K+) and extracellular sodium (Na+) concentrations in nerve cells plays an important role in the functional activities of the nervous system. The maintenance of this difference mainly depends on the number and efficiency of Na, K-ATPase. However, due to the functional activity of nerve cells, this system often loses its balance. An undetectable phenomenon is the relative deficiency of potassium in nerve cells in specific brain regions or neural network structures, which leads to dysfunction of specific nerve cell populations or brain regions, thus leading to different types of neurological disorders or diseases. The relative deficiency of potassium ions in nerve cells may be caused by the competitive failure of nerve cells to effectively use potassium ions stored in the body, and the core reason may be related to insufficient potassium obtained through diet or effectively absorbed by the digestive system. Therefore, a simple strategy is to treat a patient by taking appropriate potassium orally. This paper presents a case with great success by using such a method to treat a patient with major depression.

Darwin’s theory of evolution believes that biological evolution is a process of natural selection. This theory has been supported by much evidence, but the internal biological mechanism is not clear. Here, I elaborate on the cycle of potassium resources on the earth and the biological utilization and efficiency, which may be the core mechanism of natural selection and affect the evolution of organisms and the development of human society.

Relative Deficiency of Intracellular Potassium in Relation to the Functional Changes and Diseases in Non-Nervous System

引用

Natural Science 2022年第11期14卷 497-502页

作者： jiapei dai Wuhan Institute for Neuroscience and Neuroengineering South-Central Minzu University Wuhan China

Because of the huge differences in cellular structures and functions in non-nervous system and interaction between the nervous and non-nervous systems in potassium ion absorption, storage and effective utilization, the organs, tissues and tissue cells in non-nervous system have different functional dependence on potassium ion and its characteristics in competitive distribution differences. Therefore, I propose that the relative deficiency of potassium in cells in non-nervous organs and tissues may show very different functional changes and disease characteristics. Some are susceptible to pathogenic microorganisms, some may result in decrease of cell functions, and other may have comprehensive changes such as chronic inflammation. Therefore, the core causes for the functional changes and lesions of these non-nervous organs and tissues are closely related to the relative deficiency of potassium ions in their cells, which provides important ideas for the prevention and treatment of these functional changes and diseases.

The Continuous Relative Deficiency of Intracellular Potassium Is a Core Mechanism for the Occurrence and Metastasis of Tumor Cancer Cells

引用

Natural Science 2022年第11期14卷 492-496页

作者： jiapei dai Wuhan Institute for Neuroscience and Neuroengineering South-Central Minzu University Wuhan China

The core mechanism for occurrence of tumor cancer cells is related to the continuous relative deficiency of potassium ions in the cells of organs and tissues, which results in embryonic like proliferation and differentiation in the affected cells. The purpose of the metastasis of cancer cells is to obtain and utilize the potassium resources in other organs in body. However, if the overall potassium storage in body is obviously insufficient, the metastatic cancer cells still fail to achieve the purpose of obtaining enough potassium and turn into normal cells, further proliferation and differentiation of cancer cells will continue, and finally will lead to functional decline in the organs and tissues affected or death. Therefore, the key means to prevent and treat tumors and cancers is to ensure the normal and balanced potassium ions in cells in various organs and tissues, so as to avoid the formation of tumors and cancer cells caused by obvious deficiency of potassium ions.

LiNi0.8Co0.1Mn0.1O_(2)(NCM811),a Ni-rich layered oxide,is a promising cathode material for high-energy density lithium-ion batteries(LIBs).However,its structural instability,caused by adverse phase transitions and continuous oxygen release,as well as deteriorated interfacial stability due to excessive electrolyte oxidative decomposition,limits its widespread application.To address these issues,a new concept is proposed that surface targeted precise functionalization(STPF)of the NCM811 cathode using a synergistic slurry additive(SSA)approach.This approach involves coating the NCM811 particle surface with 3-aminopropyl dimethoxy methyl silane(3-ADMS),followed by the precise deposition of ascorbic acid via an acid-base interaction.The slurry additives induce the formation of an ultra-thin spinel surface layer and a stable cathode–electrolyte interface(CEI),which enhances the electrochemical kinetics and inhibits crack propagation.The STPF strategy implemented by the SSA approach significantly improves the cyclic stability and rate performance of the NCM811 cathode in both half-cell and full-cell configurations.This work establishes a promising strategy to enhance the structural stability and electrochemical performance of nickel-rich cathodes and provides a feasible route to promote practical applications of high-energy density lithium-ion battery technology.
