ABSTRACT

Total hip arthroplasty plays a key role in the end-stage diagnosis and treatment of a variety of femoral and hip diseases, but the risk of dislocation caused by traditional bone cement prosthesis has always been one of the key constraints of total hip arthroplasty. Bousquet added a polymer lining between the femoral head and acetabulum to separate the activities between the lining and acetabulum. The dual mobility acetabular cup system can effectively reduce the incidence of prosthesis dislocation. The first generation of the dual mobility acetabular cup system is lined with polyethylene. With the progress of modern material medicine technology, a new type of the dual mobility acetabular cup system with smooth surface, bionic coating and high cross-linked polyethylene liner has been gradually formed, and its performance has been improved. Because of the existence of the inner liner, the distance between the femoral head and acetabulum of the dual mobility acetabular cup system is larger, which can allow greater range of motion, has higher stability, is not easy to dislocate, and has lower wear degree of the prosthesis at the same time. Therefore, the dual mobility acetabular cup system is more and more widely used in clinical practice, especially for the elderly with high risk of dislocation, revision surgery or neuromuscular dysfunction. But on the other hand, based on the design principle of dual motion total hip prosthesis, the disadvantages such as intraprosthetic dislocation caused by multiple factors and the lack of fixation holes result in the dual motion total hip system easily triggering acetabular loosening when targeting patients such as severe bone defects, thus limiting its further use. The dual motion total hip system can be tailored to different clinical applications, such as for populations with different characteristics, and for different methods of primary surgery, with different application strategies, thereby reducing the incidence of postoperative revision. In this paper, we take the application of the dual motion total hip acetabular system in the total hip arthroplasty as the core, and the system puts forth the principle of the dual motion total hip acetabular system, compared with traditional bone materials, introduces its advantages and disadvantages, and reveals its application strategy in the clinic, and gives an outlook for the future application of the dual motion total hip acetabular system in orthopedics.

ABSTRACT

As one of the most important components of caveolae, caveolin-1 is involved in caveolae-mediated endocytosis and transcytosis pathways, and also plays a role in regulating the cell membrane cholesterol homeostasis and mediating signal transduction. In recent years, the relationship between the expression level of caveolin-1 in the tumor microenvironment and the prognostic effect of tumor treatment and drug treatment resistance has also been widely explored. In addition, the interplay between caveolin-1 and nano-drugs is bidirectional. Caveolin-1 could determine the intracellular biofate of specific nano-drugs, preventing from lysosomal degradation, and facilitate them penetrate into deeper site of tumors by transcytosis; while some nanocarriers could also affect caveolin-1 levels in tumor cells, thereby changing certain biophysical function of cells. This article reviews the role of caveolin-1 in tumor prognosis, chemotherapeutic drug resistance, antibody drug sensitivity, and nano-drug delivery, providing a reference for the further application of caveolin-1 in nano-drug delivery systems.

ABSTRACT

Acetic acid is a common inhibitor present in lignocellulosic hydrolysate. Development of acetic acid tolerant strains may improve the production of biofuels and bio-based chemicals using lignocellulosic biomass as raw materials. Current studies on stress tolerance of yeast Saccharomyces cerevisiae have mainly focused on transcription control, but the role of transfer RNA (tRNA) was rarely investigated. We found that some tRNA genes showed elevated transcription levels in a stress tolerant yeast strain. In this study, we further investigated the effects of overexpressing an arginine transfer RNA gene tR(ACG)D and a leucine transfer RNA gene tL(CAA)K on cell growth and ethanol production of S. cerevisiae BY4741 under acetic acid stress. The tL(CAA)K overexpression strain showed a better growth and a 29.41% higher ethanol productivity than that of the control strain. However, overexpression of tR(ACG)D showed negative influence on cell growth and ethanol production. Further studies revealed that the transcriptional levels of HAA1, MSN2, and MSN4, which encode transcription regulators related to stress tolerance, were up-regulated in tL(CAA)K overexpressed strain. This study provides an alternative strategy to develop robust yeast strains for cellulosic biorefinery, and also provides a basis for investigating how yeast stress tolerance is regulated by tRNA genes.

ABSTRACT

The dynamic or flowing tumor cells just as leukemia cells and circulating tumor cells face a microenvironment difference from the solid tumors, and the related targeting nanomedicines are rarely reported. The existence of fluidic shear stress in blood circulation seems not favorable for the binding of ligand modified nanodrugs with their target receptor. Namely, the binding feature is very essential in this case. Herein, we utilized HSPC, PEG-DSPE, cholesterol and two

ABSTRACT

Although high-efficiency targeted delivery is investigated for years, the efficiency of tumor targeting seems still a hard core to smash. To overcome this problem, we design a three-step delivery strategy based on streptavidin-biotin interaction with the help of c(RGDfK), magnetic fields and lasers. The ultrasmall superparamagnetic iron oxide nanoparticles (USIONPs) modified with c(RGDfK) and biotin are delivered at step 1, followed by streptavidin and the doxorubicin (Dox) loaded nanosystems conjugated with biotin at steps 2 and 3, respectively. The delivery systems were proved to be efficient on A549 cells. The co-localization of signal for each step revealed the targeting mechanism. The external magnetic field could further amplify the endocytosis of USPIONs based on c(RGDfK), and magnify the uptake distinctions among different test groups. Based on photoacoustic imaging, laser-heating treatment could enhance the permeability of tumor venous blood vessels and change the insufficient blood flow in cancer. Then, it was noticed that only three-step delivery with laser-heating and magnetic fields realized the highest tumor distribution of nanosystem. Finally, the magnetism/laser-auxiliary cascaded delivery exhibited the best antitumor efficacy. Generally, this study demonstrated the necessity of combining physical, biological and chemical means of targeting.

ABSTRACT

Molecular target-based cancer therapy is playing a more and more important role in cancer therapy because of its high specificity, good tolerance and so on. There are different kinds of molecular targeted drugs such as monoclonal antibodies and small molecular kinase inhibitors, and more than 50 drugs have been approved since 1997. When the first monoclonal antibody, rituximab, was on the market. The development of molecular target-based cancer therapeutics has become the main approach. Based on this, we summarized the drugs approved by FDA and introduced their mechanism of actions and clinical applications. In order to incorporate most molecular targeted drugs and describe clearly various characteristics, we divided them into four categories: drugs related to EGFR, drugs related to antiangiogenesis, drugs related to specific antigen and other targeted drugs. The purpose of this review is to provide a current status of this field and discover the main problems in the molecular targeted therapy.

ABSTRACT

The aimed of this study was to prepare stabilized thiomers to overcome the poor stability character of traditional thiomers. Poly(acrylic acid)-cysteine (PAA-Cys) was synthesized by conjugating cysteine with poly(acrylic acid) and poly(acrylic acid)-cysteine-6-mercaptonicotinic acid (PAA-Cys-6MNA, stabilized thiomers) was synthesized by grafting a protecting group 6-mercaptonicotinic acid (6MNA) with PAA-Cys. The free thiol of PAA-Cys was determined by Ellmann's reagent method and the ratio of 6MNA coupled was determined by glutathione reduction method. The study of permeation enhancement and stabilized function was conducted by using Franz diffusion cell method, with fluorescein isothiocyanate dextran (FD4) used as model drug. The influence of polymers on tight junctions of Caco-2 cell monolayer was detected with laser scanning confocal fluorescence microscope. The results indicated that both PAA-Cys and PAA-Cys-6MNA could promote the permeation of FD4 across excised rat intestine, and the permeation function of PAA-Cys-6MNA was not influence by the pH of the storage environment and the oxidation of air after the protecting group 6MNA was grafted. The distribution of tight junction protein of Caco-2 cell monolayer F-actin was influenced after incubation with PAA-Cys and PAA-Cys-6MNA. In conclusion, stabilized thiomers (PAA-Cys-6MNA) maintained the permeation function compared with the traditional thiomers (PAA-Cys) and its stability was improved. The mechanism of the permeation enhancement function of the polymers might be related to their influence on tight junction relating proteins of cells.

ABSTRACT

iRGD-modified sterically stabilized liposomes loaded doxorubicin (iRGD-SSL-DOX) were prepared and their cellular toxicity and anti-tumor efficacy were evaluated, comparing to doxorubixin loaded sterically stabilized liposomes (SSL-DOX) and RGD modified doxorubixin loaded sterically stabilized liposomes (RGD-SSL-DOX). The iRGD peptide, with both tumor targeting and cell penetrating functions, was conjugated to DSPE-PEG-NHS and DSPE-PEG-iRGD was obtained. DSPE-PEG-RGD was gained in the same way. iRGD-SSL-DOX, RGD-SSL-DOX and SSL-DOX were prepared by ammonium sulfate gradient method. The size and zeta potential of the liposomes were characterized by dynamic laser light scattering. The cellular toxicity study was done on B16 melanoma cell line and the anti-tumor efficacy study was carried on B16 cell line bearing C57BL/6 mice. The results showed that the particle sizes of liposomes were all around 90-100 nm. DOX entrapment efficiency was above 95%. The formulations were with good preparation reproducibility. iRGD-SSL-DOX showed no significant difference in B16 cellular toxicity with SSL-DOX and RGD-SSL-DOX, but the anti-tumor efficacy on B16 melanoma bearing C57BL/6 mice was significantly better than that of SSL-DOX, similar as that of RGD-SSL-DOX. Therefore, iRGD modified liposomes loaded DOX would be a promising drug delivery system for tumor therapy.

ABSTRACT

The transcellular process of coumarin 6 (C6) loaded poly(ethyl ethylene phosphate)-co-poly (epsilon-caprolactone) (PEG-PCL) micelles on Madin-Darby Canine Kidney (MDCK) epithelial cells was investigated. C6 loaded PEG-PCL micelles were prepared using the thin-film hydration method. The size of the micelles was characterized by dynamic light scattering analysis using a Malvern Zetasizer Nano ZS. The critical micelle concentration (CMC) was determined by pyrene fluorescence probe method. And the transcellular process of the micelles on MDCK epithelial cells was investigated by using transmission electron microscope, laser confocal scanning microscope and Förster resonance energy transfer technology. It turned out that the size of PEG-PCL micelles was about 30 nm and CMC was 1.01 microg x mL(-1). PEG-PCL micelles were endocytosed in intact form and they could deliver hydrophobic drugs across the basolateral membrane of the epithelial cells. However, PEG-PCL is hardly being transported in micelle formation itself. The transportation of C6 by PEG-PCL micelles was through the transcellular pathway, yet not the paracellular pathway.
