Preparation and hemostatic evaluation of carboxymethyl chitosan/gelatin/clinodiside a composite sponges.

In trauma resuscitation, rapid hemostasis is a top priority for rescuing patients from the risk of hemorrhagic shock and infection. Traditional hemostatic materials are not effective for hemostasis and have some limitations. We added "Duanxue Liu" saponin A (Clinodiside A) to a hemostatic sponge based on carboxymethyl chitosan (CMCS) and gelatin to improve its hemostatic effect.

Ketoconazole-loaded microspone film coating agent for superficial fungal infection: design, preparation and characterization.

Ketoconazole (KCZ), an imidazole antifungal drug, is constrained by its low solubility and poor stability, restricting its effective absorption and bioavailability. This study introduces a KCZ-loaded microsponge based film coating agent (KCZ-MSF), designed to enhance the transdermal absorption and bioavailability of KCZ. The KCZ-MS was prepared by emulsion solvent evaporation method and the composition of the prescription was optimized by Box-Behnken design (BBD).

Minimally invasive treatment of fungal keratitis with voriconazole microneedle corneal patch.

Fungal keratitis, a disease caused by fungal infection of the cornea, is an eye disease with a high rate of blindness. Despite voriconazole (VCZ) has a good therapeutic effect in the treatment of fungal infection, the use of VCZ in the eye is limited due to the poor solubility of VCZ and the special physiological structure of the eye. In this study, a soluble microneedle (MN) containing VCZ micelles was designed for the eye to effectively deliver VCZ for the treatment of fungal keratitis.

The predictive value of blood neutrophil-lymphocyte ratio in patients with end-stage liver cirrhosis following ABO-incompatible liver transplantation.

Background: The study was designed to assess the role of preoperative neutrophil, lymphocyte, and neutrophil-lymphocyte ratio (NLR) in predicting survival outcomes of ABO-incompatible liver transplantation (LT).

Materials And Methods: We retrospectively collected the demographic and clinical characteristics of 71 patients with end-stage liver cirrhosis following ABO-incompatible LT in this study. Kaplan-Meier survival analysis and Cox multiple factors regression analysis were performed to determine the independent risk factors from preoperative blood parameters for poor prognosis.

FAM83D associates with high tumor recurrence after liver transplantation involving expansion of CD44+ carcinoma stem cells.

To investigate the potential oncogene promoting recurrence of hepatocellular carcinoma (HCC) following liver transplantation (LT), throughput RNA sequencing was performed in a subgroup of HCC patients. The up-regulated FAM83D in HCC tissues was found and further verified in 150 patients by real-time PCR and immunohistochemistry. FAM83D overexpression significantly correlated with high HCC recurrence rate following LT and poor HCC characteristics such as high AFP, poor differentiation.

MicroRNA-452 promotes stem-like cells of hepatocellular carcinoma by inhibiting Sox7 involving Wnt/β-catenin signaling pathway.

The decrease of microRNA-452 (miR-452) in gliomas promoted stem-like features and tumorigenesis. However, the role of miR-452, especially in regulating cancer stem cells (CSCs) in hepatocellular carcinoma (HCC) remains ambiguous. We enriched stem-like HCC cells by serial passages of hepatospheres with chemotherapeutic agents.

In this study, we aimed to investigate the prognostic role of peritransplant ALC and ALC recovery after liver transplantation (LT) in hepatocellular carcinoma (HCC) patients.

Methods: A total of 269 HCC patients undergoing LT were enrolled in our study.

Role of overexpression of MACC1 and/or FAK in predicting prognosis of hepatocellular carcinoma after liver transplantation.

Background: Metastasis-associated in colon cancer-1 (MACC1) acts as a promoter of tumor metastasis; however, the predictive value of MACC1 for hepatocellular carcinoma (HCC) after liver transplantation (LT) remains unclear.

Methods: We examined the expression of MACC1 and its target genes MET and FAK by quantitative PCR in 160 patients with HCC that was undergone LT.

Results: The patients with MACC1(high) or FAK(high) in HCCs showed a significantly shorter overall survival and higher cumulative recurrence rates after liver transplantation (LT), compared with MACC1(low) or FAK(low) group.

Single nucleotide polymorphisms in the metastasis-associated in colon cancer-1 gene predict the recurrence of hepatocellular carcinoma after transplantation.

Background: The newly identified metastasis-associated in colon cancer-1 (MACC1) gene is involved in angiogenesis, epithelial-to-mesenchymal transition (EMT), invasiveness, and metastasis in a variety of malignancies. Overexpression of MACC1 gene is a prognostic marker for poor outcome of hepatocellular carcinoma (HCC) patients. However, the association between genetic polymorphisms of MACC1 gene and poor outcome in HCC has been not been performed.
