In past 5 years, ever the global pandemic of COVID-19, as a new infectious disease, has undergone extensive and in-depth research on its etiology, pathology, diagnosis, prevention and treatment, as well as integrative Chinese and western medicine. The prevention, treatment and rehabilitation of integrative Chinese and Western medicine in mainland China has played an important role in management of the epidemic. One of its advantages in Chinese Medicine is that even when the cause of the infectious disease is unknown, based on the theory of Chinese medicine and past practical experience, Chinese medicine can have its own diagnosis and treatment plan, but the disadvantage is that there is a lack of modern clinical and scientific evidences. Although vaccines have been emerged one after another, and pandemic is gone, COVID-19 is still one of season diseases, and the effectiveness and safety of vaccines needs further observation, especially for people who are elder age and complicated with other diseases. This presentation intends to review the research progress and existing problems of COVID-19 in Chinese and Western medicine, focus on prevention, treatment and rehabilitation of COVID-19 by Chinese herbal medicine, and explore its scientific and clinical evidence in multicompounds and multitargets. Based on our literature review and our studies, we published several review papers and clinical studies, and awarded a Hong Kong Government grant to support our RCT study for prevention of COVID-19 by Chinese herbal medicine which will present the part of the results in the conference.

Inadvertent accumulation of arsenic (As) in rice (Oryza sativa L.) is a concern for people depending on it for their subsistence, as it verily causes epigenetic alterations across the genome as well as in specific cells. To ensure food safety, certain attempts have been made to nullify this highest health hazard encompassing physiological, chemical and biological methods. Albeit, the use of mycorrhizal association along with nutrient reinforcement strategy has not been explored yet. Molecular mechanisms of response and resistance of rice genotypes to As with or without phosphorus (P) nutrition and Serendipita indica (S. indica; S.i) colonization were explored by root transcriptome profiling in the present study. Results revealed that the resistant genotype had higher auxin content and root plasticity, which helped in keeping the As accumulation and P starvation response to a minimum under alone As stress. However, sufficient P supply and symbiotic relationship switched the energy resources towards plant’s developmental aspects rather than excessive root proliferation. Of note, this study showed that the As + S.i + P interactive treatment mellowed down the chaotic increase in heat shock proteins, and potentially induced early flowering genes by lengthening the telomere. Moreover, genes stimulating endogenous BR (CycD3) and their cross-talk with CK (Os11g0143300, Os12g0139400, Os01g0952500 and Os01g0197700), as well as SA
(Os11g0663100, Os03g0778000 and Os11g0669100), metal effluxer (P-type ATPase, K/Mg/Cd/Cu/Zn/Na/Ca/Na/H-transporter family protein) and detoxification related genes (glutathione-S-transferases), elevation of K+ transporter AKT1, Fe+ transporters (OsYSL2 and OsYSL15), and phosphate transporter PHT14, greatly contributed to As tolerance acquisition. Taken together, S. indica symbiosis fortified with adequate P-fertilizer can prove to be effective in minimizing As acquisition and accumulation in rice plants.

Termites are responsible for the significant loss of date palm production. Limitations and
hazardous side effects of chemical pesticides pushed toward finding eco-friendly alternatives to
control pests. Using semiochemicals with natural enemies has grown in recent years, making
biological control agents and semiochemicals crucial for integrated pest management of insect
pests. The current study has revealed a chemical interaction between three organisms, date palm
termites-ants. This study simplifies this complex relationship among date palms, termites and ants,
essential for effective pest management. This study investigated the impact of termite attacks and
the presence of ants on the volatile compounds profile released into the chemosphere of the
community consisting of the date palm Phoenix dactylifera, the harvester termite Anacanthotermes
ochraceus, and the ant Messor cf. wasmanni. This study aims to analyze the volatile compounds
emitted by the date palm and surrounding insects in response to these intricate interactions. The
extraction of volatile organic compounds (VOCs) was carried out using closed-loop stripping (CLS)
and then analyzed via gas chromatography-mass spectrometry (GC-MS) and Canonical analysis of
principle coordinates (CAP) was performed. Termites and ants were collected from Taif City and
molecularly identified based on the mitochondrial cytochrome oxidase I. The date palm was
exposed to different types and order of treatments, including non-infested palm, termite-infested
palm and termite-infested palm + ants. Infested date palms displayed distinct emissions of
camphene, (+)-4-careneand, 3-carene, guaiene, and (-)-aristolene compared to non-infested plants.
The characteristic VOC profile was the share of infested date palms in the presence of ants, with γterpinene, ketone, aromadendrene, isobornyl acetate and bornyl acetate. These semiochemicals play
multiple functions, such as repellent or killing activities. Termite-killing or repelling
semiochemicals can be integrated alone or with biological control agents for better and more
effective control of termites affecting palm trees. Moreover, alarming or defensive semiochemicals
of termites can be counteracted to suppress their defense mechanisms.
