Peroral administration is the most convenient one for the administration of pharmaceutically active compounds. Most of poorly water-soluble drugs administered via the oral route, however, remain poorly available due to their precipitation in the gastrointestinal (GI) tract and low permeability through intestinal mucosa. In this study, one of drug delivery carriers, lipid nanoparticles (LNPs) were designed in order to reduce side effects and improve solubility and stability in GI tract of the poorly water soluble drugs. However, plain LNPs are generally unstable in the GI tract and susceptible to the action of acids, bile salts and enzymes. Accordingly, the surface of LNPs was modified with polyethylene glycol (PEG) for the purpose of improving solubility and GI stability of paclitaxel (PTX) in vitro. PEG-modified LNPs containing PTX was prepared by spontaneous emulsification and solvent evaporation (SESE) method and characterized for mean particle diameter, entrapping efficiency, zeta potential value and in vitro GI stability. Mean particle diameter and zeta potential value of PEG-modified LNP containing PTX showed approximately 86.9 nm and -22.9 mV, respectively. PTX entrapping efficiency was about 70.5% determined by UV/VIS spectrophotometer. Futhermore, change of particle diameter of PTX-loaded PEG-LNPs in simulated GI fluids and bile fluid was evaluated as a criteria of GI stability. Particle diameter of PTX-loaded PEG-LNPs were preserved under 200 nm for 6 hrs in simulated GI fluids and bile fluid at $37^{\circ}C$ when DSPE-mPEG2000 was added to formulation of LNPs above 4 mole ratio. As a result, PEG-modified LNPs improved stability of plain LNPs that would aggregate in simulated GI fluids and bile solution. These results indicate that LNPs modified with biocompatible and nontoxic polymer such as PEG might be useful for enhancement of GI stability of poorly water-soluble drugs and they might affect PTX absorption affirmatively in gastrointestinal mucosa.

Glaucoma is the second leading cause of irreversible blindness, and primary open-angle glaucoma (POAG) is the most common type. Due to inadequate diagnosis, treatment is often not administered until symptoms occur. Hence, approaches enabling earlier prediction or diagnosis of POAG are necessary. We aimed to identify novel drugs for glaucoma through bioinformatics and network analysis. Data from 36 samples, obtained from the trabecular meshwork of healthy individuals and patients with POAG, were acquired from a dataset. Next, differentially expressed genes (DEGs) were identified to construct a protein-protein interaction (PPI) network. In both stages, the genes were enriched by studying the critical biological processes and pathways related to POAG. Finally, a drug-gene network was constructed, and novel drugs for POAG treatment were proposed. Genes with p < 0.01 and |log fold change| > 0.3 (1,350 genes) were considered DEGs and utilized to construct a PPI network. Enrichment analysis yielded several key pathways that were upregulated or downregulated. For example, extracellular matrix organization, the immune system, neutrophil degranulation, and cytokine signaling were upregulated among immune pathways, while signal transduction, the immune system, extracellular matrix organization, and receptor tyrosine kinase signaling were downregulated. Finally, novel drugs including metformin hydrochloride, ixazomib citrate, and cisplatin warrant further analysis of their potential roles in POAG treatment. The candidate drugs identified in this computational analysis require in vitro and in vivo validation to confirm their effectiveness in POAG treatment. This may pave the way for understanding life-threatening disorders such as cancer.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are immune-complex-mediated hypersensitivity reactions that predominantly involve skin and mucous membranes. Despite the low incidence, both are considered medical emergencies as the mortality rate has been estimated at 30-50%. Although as many as half of cases are idiopathic, several drugs have been implicated as main cause of SJS/TEN. This review therefore aimed to identify drugs that were potentially associated with SJS/TEN and compare the relative risk of the medications. Method: A comprehensive search was performed using MEDLINE, EMBASE and 5 Korean databases. We defined study drugs as non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, antiepileptics, and allopurinol. Only epidemiologic studies investigating associations between the above drugs and drug-induced SJS/TEN were included. Two reviewers independently selected and evaluated candidate papers and extracted odds ratios or incidence rates. Meta-analysis was performed only for drugs that were reported from 4 or more studies. Results: We found 8 case-control studies, 3 cohort studies and 1 RCT. The ranges of adjusted ORs were 0.6-34.0 for NSAIDs, 1.6-302.0 for antiepileptics, 0.3-10.0 for antibiotics and 1.0-187.0 for allopurinol. The drug with the highest incidence of SJS/TEN was carbamazepine (40 persons/1,000 DDD). Conclusion: Finally, the risk was highest in first 8 weeks after onset of treatment in all drugs.

Gastrointestinal (GI) cancers are top priorities for cancer control in Korea. In terms of epidemiological, population-health and economic burden, GI cancers such as stomach, liver and colorectal cancers have been top four cancers in the nation during the past decade and this trend is likely to continue in the near future. In order to reduce the great burden of GI cancer in Korea, the nation might need the following strategies: (1) to put more focus on primary prevention on infection/diet and related research; (2) to improve screening rates for colorectal and stomach cancers, and conduct more cost-effectiveness analysis of these screening programs, e.g., Fecal Occult Blood Test vs. colonoscopy; (3) to establish a more consistent and integrative cost-effectiveness analysis system for new cancer treatments and anticancer drugs; and (4) to place more emphasis on hospice and other palliative care of GI cancer, as well as on the etiology, staging and treatment of pancreas cancer with its poor survival rate.
