Traditional Chinese Medicine (TCM) has been extensively used to ameliorate diseases in Asia for over thousands of years. However, owing to a lack of formal scientific validation, the absence of information regarding the mechanisms underlying TCMs restricts their application. After oral administration, TCM herbal ingredients frequently are not directly absorbed by the host, but rather enter the intestine to be transformed by gut microbiota. The gut microbiota is a microbial community living in animal intestines, and functions to maintain host homeostasis and health. Increasing evidences indicate that TCM herbs closely affect gut microbiota composition, which is associated with the conversion of herbal components into active metabolites. These may significantly affect the therapeutic activity of TCMs. Microbiota analyses, in conjunction with modern multiomics platforms, can together identify novel functional metabolites and form the basis of future TCM research.

Background/Aims: Direct‐acting antivirals (DAAs) have been approved for hepatitis C virus (HCV) treatment in patients with end-stage renal disease (ESRD) on hemodialysis. Nevertheless, the complicated comedications and their potential drug-drug interactions (DDIs) with DAAs might limit clinical practice in this special population. Methods: The number, class, and characteristics of comedications and their potential DDIs with five DAA regimens were analyzed among HCV-viremic patients from 23 hemodialysis centers in Taiwan. Results: Of 2,015 hemodialysis patients screened in 2019, 169 patients seropositive for HCV RNA were enrolled (mean age, 65.6 years; median duration of hemodialysis, 5.8 years). All patients received at least one comedication (median number, 6; mean class number, 3.4). The most common comedication classes were ESRD-associated medications (94.1%), cardiovascular drugs (69.8%) and antidiabetic drugs (43.2%). ESRD-associated medications were excluded from DDI analysis. Sofosbuvir/velpatasvir/voxilaprevir had the highest frequency of potential contraindicated DDIs (red, 5.6%), followed by glecaprevir/pibrentasvir (4.0%), sofosbuvir/ledipasvir (1.3%), sofosbuvir/velpatasvir (1.3%), and elbasvir/grazoprevir (0.3%). For potentially significant DDIs (orange, requiring close monitoring or dose adjustments), sofosbuvir/velpatasvir/voxilaprevir had the highest frequency (19.9%), followed by sofosbuvir/ledipasvir (18.2%), glecaprevir/pibrentasvir (12.6%), sofosbuvir/velpatasvir (12.6%), and elbasvir/grazoprevir (7.3%). Overall, lipid-lowering agents were the most common comedication class with red-category DDIs to all DAA regimens (n=62), followed by cardiovascular agents (n=15), and central nervous system agents (n=10). Conclusions HCV-viremic patients on hemodialysis had a very high prevalence of comedications with a broad spectrum, which had varied DDIs with currently available DAA regimens. Elbasvir/grazoprevir had the fewest potential DDIs, and sofosbuvir/velpatasvir/voxilaprevir had the most potential DDIs.

Zerumbone(ZER), one of humulane-type sesquiterpenoids, showed its unique advantage against tumor activities. The main underlying mechanisms include inhibiting the growth and proliferation of cancer cells, inducing apoptosis of cancer cells and differentiation of cancer cells, regulating immune function, inhibiting invasion and metastasis of cancer cells, and reversing multidrug resistance of cancer cells. Studies on ZER focusing its cytotoxic or anti-tumor is one of hot topic. Currently, with the increasing studies on ZER, the clarified mechanisms are getting rich. The present paper describes a summary of its anti-tumor mechanism of action and helps to provide significant reference to more in-depth research.

Objective To study manipulating time and feasibility of simulated decompression craniectomy aboard ship under different sea status.Methods A hydraulic simulator was used to simulate the 4 different rolling and pitching states of the ship (i.e.A、B、C and D).Twenty hybrid dogs were randomly divided into groups for our present study.Simulated decompression craniectomy was performed to measure manipulating time and carry out feasibility study.Results Decompression craniectomy was completed successfully on experimental dogs without any death occurred following an observation of at least 48 hours.No differences in manipulating time could be noted(P>0.05).Conclusions Though manipulating accuracy aboard ship was affected to a certain degree,decompression craniectomy could be performed aboard ship under the four sea states.
