    Phenolic compounds are widely used in natural plant foods and have strong antioxidant properties, so they are widely used in food and medicine. The reaction between the phenolic compound and the protein can affect the functional properties of the protein, such as emulsifying properties, gel properties, solubility, thermal stability, and foaming properties. The mechanism of interaction between phenolic compounds and proteins are described from the aspects of non-covalent interaction and covalent interaction, and the characterization methods of the interaction mechanism between phenolic compounds and proteins are described. The indexes for characterizing the covalent bonding of phenolic compounds and proteins include the free amino group content, total sulfhydryl content, tryptophan content. Ninhydrin method, 2,4,6-trinitrobenzenesulfonic acid (TNBS) method, o-phthal- aldehyde (OPA) method and high-performance liquid phase chromatography were applied to o measure the free amino group content. Ellman’s method was applied to investigate total sulfhydryl content. Fluorescence measurements can be used for changes in tryptophan modification. The indexes for characterizing the con-covalent bonding of phenolic compounds and proteins include hydrogen bonding, hydrophobic interactions, disulfide bonds and hydrophobicity of protein surface. Hydrogen bonding, hydrophobic interactions and disulfide bonds can be investigated by Gómez-Guillén’s method.

    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.

    The solution structure and function of human coagulation factor X (FX) were studied to understand the key structural elements of the enzyme form during activation. FX is a vitamin K-dependent plasma glycoprotein, composed of light and heavy chains, and plays a central role in the coagulation cascade. The calcium-rich γ-carboxyglutamic acid domain is responsible for binding to the membrane, an important step in the coagulation process. After activation, the serine protease domain undergoes a significant relocation, forming a compact multidomain. The S1-specific pocket largely determines the functional activities that activate FX. The enzyme-producing form of FX is more extensive than the active form. The enzyme-producing and activated forms of FX have different conformations in the serine protease domain.

    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.

    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.

    To develop an effective deodorant and antibacterial agent, we prepare a Ti doped nano-ZnO through a low temperature hydrothermal route. The shape and size of these as-prepared samples can be tuned effectively by controlling the reaction conditions, such as the molar ratio of Ti/Zn. Furthermore, the sample with an appropriate portion of Ti and Zn is selected to obtain dispersion for improving sample activity and avoiding sample agglomeration. XRD, SEM, EDX and DLS are performed to characterize the structure and morphology of samples. Furthermore, the typical dispersion is used to remove odorous molecules and kill bacteria. The results show that polycarboxylic acid can be used to improve the dispersibility and stability of nanoparticles, and the well-dispersed dispersion is high effective for deodorization and antibiosis. Moreover, CCK-8 assays are performed to evaluate the cytotoxicity of dispersions with different size. The result reveals that dispersion with a smaller particle size displayed more serious toxicity. Thus, we suggest that the obtained dispersion can be used as a deodorant and antibacterial agent, but it is necessary to take precautions when handling the dispersion because the nanoparticles, special smaller nanoparticles is more likely to cause serious cytotoxicity.

    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.

    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.

    Microtubules are heterodimers composed of α/β tubulin and make up the cytoskeleton. It plays an important role in maintaining cellular morphology, cell division, signal transduction and other processes. At present, six tubulin inhibitor binding sites have been identified. The inhibitors can be divided into two categories: a type of microtubule polymerization agent includes colchicine site, vinblastine site, maytansine site and prionetin site inhibitors; another category is paclitaxel and laulimalide/peloruside binding site inhibitors are called microtubule depolymerization. Herein, we summarize relevant inhibitors acting on these 6 sites and their research status. With extensive research on tubulin binding sites and inhibitors, anti-tumor tubulin inhibitors will possess very broad clinical prospects.
