    Qualified prescribing is fundamental for appropriate use of medicine. Pharmacist interventions potentially remind physicians to cope with this issue. This study aimed to report interventions implemented by pharmacists with real-time computer-based alert system and evaluate the prescription errors for outpatients in a Chinese tertiary hospital. This retrospective, non-comparative study was implemented with an analysis of data collected from October to December in 2018 involved all clinical specialty departments in the hospital. Alerts were generated and displayed on pharmacist screen while prescribing inappropriately, then pharmacists chose certain operation and offered recommendations according to the alerts. Outcomes such as category and acceptance rate of pharmacist recommendations, prescription error types, prevalence rate, severity level and monthly tendency were documented, categorized and analyzed. In our study, 2.3% of prescriptions generated alerts, and incidence of pharmacist interventions was 0.19%. 431 prescription errors were prevented, with the overall acceptance rate of interventions accounted for 29.7%. Dosage or frequency problems ( n = 170, 39.5%), contraindications ( n = 79, 18.3%) and improper duration of pharmacotherapy ( n = 53, 12.3%) were the top three types of prescription errors. Monthly rate of errors decreased from 0.98 to 0.43 per 1000 prescriptions in the monitoring period. Pharmacist interventions with computer-based alert system were available for filtering part of invalid alerts and preventing prescription errors in our study.

    Oxaliplatin (L-OHP) is a new platinum anticancer drug, which is used for the treatment of metastatic colorectal cancer or the adjuvant treatment of stage III colon cancer. T-cell acute lymphoblastic leukemias (T-ALLs) are invasive thymocytic malignant tumors with poor prognosis. The purpose of this study was to evaluate the cytotoxic effect of L-OHP on human T-ALL cell lines MOLT-4, Jurkat, CCRF-CEM, and CEM/C1 cells. The CCK-8 method results showed that L-OHP significantly inhibited T-ALL cells proliferation. The inhibition of these T-ALL cells prolife by L-OHP seems to be related to the induction of cell cycle arrest. The effect of L-OHP on the cell cycle distribution of T-ALL cells varies with cell types. As to cells apoptosis, Annexin V/Propidium iodide assay disclosed that L-OHP prominently induced T-ALL cells apoptosis by activating the pathways of mitochondrial biogenesis and is more sensitive to MOLT-4 cells. Western blot analysis showed that L-OHP treatment could promote apoptosis through down-regulated Bcl-2 protein level, up-regulated Bax and caspase-9 proteins levels and cell cycle arrest by inhibiting the PI3K/Akt signaling pathway in MOLT-4 cells. Our results indicate that L-OHP, as a new type of platinum anticancer drug, may attract more attention in the future treatment of T-ALL.

    Glucokinase (GK), as a key enzyme regulating carbohydrate metabolism, has been widely researched as a therapeutic target for diabetes. This study aimed to investigate the influence of magnesium ion concentration, ATP concentration, and enzyme concentration on the catalytic activity of GK by response surface. A cellular model of insulin resistance (IR) was established to observe the ameliorating effect of magnesium ion on IR by screening the concentration and duration of insulin action. The results indicated that the optimal concentrations for enzyme activity were found to be 1.1 mM for magnesium ion, 1.4 mM for ATP, and 0.5 U/mL for glucokinase. In the presence of taurine, the IR model was treated with magnesium ion (1.1 mM) can promote glucose consumption, GK activity and intracellular magnesium concentration in IR cells. Magnesium ion, as a key factor in GK-catalyzed glycolysis, showed a positive correlation between intracellular magnesium ions and the catalytic activity of GK within a certain concentration range. Therefore, magnesium ion could effectively promote carbohydrate metabolism and alleviate the progression of IR.

    Vaginal microorganisms, dominated by Lactobacillus spp., are an important defense against infections including pathogenic sexually transmitted infections. Extracellular vesicles (EVs) are recognized and endocytosed by tissue cells through specific interactions between membrane surface proteins, and thereafter deliver their molecular cargo. Bacteria can use their EVs to interact with neighboring bacteria and play an important role in the physiology and pathogenesis of cells. Herein, we investigated whether the bacteriostatic effect of Lactobacillus was mediated by extracellular vesicles released by these bacteria. L. gasseri-derived EVs were isolated by ultracentrifugation and loaded with metronidazole to observe their antibacterial activity. Our results showed that L. gasseri-derived EVs could effectively encapsulate drug, enhanced drug retardation, and had good biosafety. EVs and EVs-metronidazole have inhibitory effects on E. coli, S. aureus, and L. monocytogenes, with the best inhibitory effect on L. monocytogenes. Together, our work provides a new potential strategy for vaginitis treatment.

    The aim of this study was to investigate the benefits of incorporation of graphene oxide-silica (GO@SiO2) on the degree of conversion and bond strength of an experimental dental adhesive. The GO@SiO2 nanocomposites were prepared and characterized by using FTIR, Raman and TEM. After that, GO@SiO2 was added into an experimental dental bonding system as novel nanofiller, and the effect of the modification on the dispersion stability of the GO@SiO2 nanocomposites in the experimental adhesive was studied. In addition, the degree of conversion was characterized by real-time FTIR, and the light conversion kinetic curves were calculated. Furthermore, the bond strength of the experimental adhesive to dental restorative resin was investigated. The result showed that the GO@SiO2 nanocomposites dispersed well in the experimental adhesive, and the introduction of GO@SiO2 improved effectively the degree of conversion of the dental adhesive after curing. In addition, the experimental adhesive filled with GO@SiO2 nanocomposites showed not only similar bond strength to a commercial adhesive, but also enhanced dramatically compressive strength as well. Furthermore, the obtained experimental dental adhesives can increase reactive oxygen species level in cells through photothermal conversion to be used in potential therapy.

    Skin is the largest human organ, which always suffered from environmental stresses, as well as extrinsic and intrinsic noxious agents. Although skin can take different protective mechanisms to maintain balance, excessive stresses can disrupt these systems, resulting in the formation of skin cancers, including both melanoma and non-melanoma skin cancers. Phytochemicals are biologically active compounds derived from plants and herbal products, which appear to be beneficial in the battle against cancer as they exhibit anti-cancer effects and are inexpensive, widely available, and well tolerated. Studies have demonstrated that phytochemicals can act on various cellular processes including cell cycle, apoptosis and redox metastasis to inhibit the development and progression of skin cancer. This article mainly focuses on the progress in anti-skin cancer activity of phytochemicals and underlying molecular mechanisms, which will hopefully provide valuable insights into clinical applications of phytochemicals for treatment of skin cancers.

    Transient receptor potential ankyrin 1 (TRPA1) is an ion channel involved in nociception. In addition, TRPA1 activation triggers an inflammatory response, which intensifies the sensation of pain. The role of TRPA1 in pain makes it an attractive target for painkiller drug design. The research on TRPA1 antagonists and agonists has increased in recent years with the focus on discovering novel and effective TRPA1 antagonists. This minireview describes some computational drug design methods that have been applied for examining TRPA1 and its ligands. So far, three ligand binding sites have been proposed for TRPA1. The binding of various ligands into TRPA1 has been explored with molecular docking and molecular dynamics. This is the first review that con-centrates on TRPA1 computational studies.

    Caffeine (1,3,7-trimethylxanthine) is the most frequently ingested neuroactive drug in the world and has enigmatic effects on tumor cells. Convincing evidence from in vitro, animal and human studies suggests that caffeine can inhibit cancer development and progression. Caffeine can easily pass through biological mem-branes and cross the blood-brain barrier, and it is thereby possible to bind to extracellular or intracellular molecules to exert its functions. This review mainly focuses on recent advances in the direct interaction targets of caffeine in the inhibition of malignancies and will hopefully provide valuable insights into the clinical application of caffeine to the treatment of cancers.

    Taking Larimichthys polyactis, a rare seafood from Zhejiang Province, as the research object, sensory evaluation, pH, microbial analysis, texture, water retention, K value, total volatile basic nitrogen (TVB-N value), TCA-soluble peptide, thiobarbiturate acid value, the effects of ordinary packaging, vacuum packaging and air-conditioned packaging on the quality of Larimichthys polyactis during the refrigeration process were studied. The results showed that the sensory comprehensive score, texture and water retention of Larimichthys polyactis were gradually decreased with the extension of refrigeration time. The TVB-N value and TBA value of Larimichthys polyactis under the three different packaging treatments increased with the extension of time, and the change of K value was consistent with the TVB-N value. The TVB-N value, TBA value and K value of Larimichthys polyactis in air-conditioned packaging group increased slowly. The content of TCA-soluble peptide indicated that both vacuum and air-conditioned packages had a good effect on inhibiting protein degradation. According to the evaluation indexes, the air conditioning package is beneficial to keep the freshness of Larimichthys polyactis under the cold storage condition.

    This study explores the inhibitory effect of triptolide on ovarian cancer cells through in vitro cell and in vivo animal model experiments. We use the CCK-8 survival rate experiment to determine appropriate concentration of triptolide and the type of cell line including SF9, HEK293, A2780 and Skov-3. Furthermore, the cell invasion and migration of A2780 and Skov-3 cells shows that triptolide had a strong inhibitory effect on ovarian cancer cell line. In addition, flow cytometry is used to detect the apoptosis and cycle of A2780 cells. The results prove that the proliferation of ovarian cancer cell lines is significantly inhibited by triptolide at a 200 nmol/L concentration. Finally, in vivo animal model shows a strong inhibitory effect of triptolide with a 200 nmol/L concentration on ovarian cancer. However, HE staining of animal liver, kidney and ovarian tissue section reveals that there is a stronger effect of 200 nmol/L triptolide on the damage of living organs coming from its toxicity. The result offers a chance for reasonable safety use of triptolide.

    In the past decades, many polyethylene glycol (PEG)-containing polymers were developed and widely utilized to prepare functionalized nano delivery systems with hydrophilic shielding feature and high body fluid/environmental stability. Notably, some surface physicochemical properties of the PEG-containing polymers largely determined their solution properties and interactions with other biomolecules, which thus subsequently influenced their biological behaviors. In this paper, we summarized recent advances on the surface physicochemical properties of PEG-containing polymer nano systems and their impacts on self-assembly, solution stability, biomolecular interactions, as well as drug delivery.
