Objective Soft and hard channel minimally invasive interventions for patients with hypertensive intracerebral hemorrhage have been used for many years. A retrospective study was performed to evaluate the superiority of these two methods. Methods 122 patients with hypertensive intracerebral hemorrhage were included in this retrospective study, 64 cases in soft channel group and 58 cases in hard channel group. The clinical effects were compared; catheter retention time and complications of the minimally invasive surgery were also observed in these two groups. Results In soft channel group, NIHSS before the treatment was 18.05±7.77, and NIHSS after the treatment was 7.57±4.68. The mortality was 17.19%. The catheter retention time in hematoma puncture was (4.35±1.56)days, and the catheter retention time in ventricle puncture was (7.67±2.37)days. There were 4 cases of rebleeding and 3 cases of intracranial infection. In hard channel group, NIHSS before the treatment was 18.38±9.02, and NIHSS after the treatment was 8.02±4.84. The mortality was 20.69%. The catheter retention time in hematoma puncture was (4.07±1.49)days, and the catheter retention time in ventricle puncture was (8.17±2.55)days. There were 9 cases of rebleeding and 2 cases of intracranial infection. The differences were not statistically significant (P>0.05). Conclusions Soft and hard channel minimally invasive interventions of hypertensive cerebral hemorrhage have the same clinical value.

Integrating various pathway data collections to create new biological knowledge is a challenge, for which novel computational tools play a key role. For this purpose, we developed the Java-based conversion modules KGML2SBML and KGML2BioPAX to translate KGML (KEGG Markup Language) into a couple of common data exchange formats: SBML (Systems Biology Markup Language) and BioPAX (Biological Pathway Exchange). We hope that our work will be beneficial for other Java developers when they extend their bioinformatics system into SBML- or BioPAX-aware analysis tools. This is part of our ongoing effort to develop an ultimate KEGG-based pathway enrichment analysis system.

The ezrin-radixin-moesin (ERM) proteins are a family of membrane-associated proteins known to play roles in cell-shape determination as well as in signaling pathways. We have previously shown that amphetamine decreases phosphorylation levels of these proteins in the nucleus accumbens (NAcc), an important neuronal substrate mediating rewarding effects of drugs of abuse. In the present study, we further examined what molecular pathways may be involved in this process. By direct microinjection of LY294002, a PI3 kinase inhibitor, or of S9 peptide, a proposed GSK3β activator, into the NAcc core, we found that phosphorylation levels of ERM as well as of GSK3β in this site are simultaneously decreased. These results indicate that ERM proteins are under the regulation of Akt-GSK3β signaling pathway in the NAcc core. The present findings have a significant implication to a novel signal pathway possibly leading to structural plasticity in relation with drug addiction.

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.

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.
