All-natural hydrogel composed of carboxymethyl chitosan and oxidized dextran for promoting wound healing by immune-microenvironment regulation.

Chronic wound treatment has always been a major clinical challenge owing to complex and dynamic wound microenvironment. The design and development of effective management with antimicrobial activity, ROS-scavenging and regulation immune response is vital for tissue repair. Herein, we developed puerarin (PUE) loaded a double network hydrogel consisting of methacrylated carboxymethyl chitosan and oxidized dextran with Schiff base and photo-crosslinking reaction.

Total flavonoids of Litchi chinensis Sonn. seed inhibit prostate cancer growth in bone by regulating the bone microenvironment via inactivation of the HGFR/NF-κB signaling pathway.

Ethnopharmacological Relevance: Litchi chinensis Sonn. (Litchi) seed, a traditional Chinese medicine, is habitually used in the clinical treatment of prostate cancer (PCa)-induced bone pain. In our previous study, flavonoids have been identified as the active ingredient of litchi seed against PCa.

Efficacy and safety of Fuzheng Huayu tablet on persistent advanced liver fibrosis following 2 years entecavir treatment: A single arm clinical objective performance criteria trial.

Ethnopharmacological Relevance: Antiviral therapy can alleviate liver fibrosis in chronic hepatitis B, but it has a limited effect on advanced liver fibrosis/cirrhosis. Traditional Chinese medicine (TCM), particularly FuZheng HuaYu (FZHY) tablet, appears to have an antifibrotic effect, but its improving resolution of hepatitis b virus (HBV) -associated advanced fibrosis and experienced anti-viral treatment has not been investigated.

Aim Of The Study: To observe the safety and efficacy of adjunctive FZHY on the HBV-associated cirrhosis patients who received 2 years of entecavir but still with advanced fibrosis.

Effect and Safety of Hydroxysafflor Yellow A for Injection in Patients with Acute Ischemic Stroke of Blood Stasis Syndrome: A Phase II, Multicenter, Randomized, Double-Blind, Multiple-Dose, Active-Controlled Clinical Trial.

Objective: To assess the effect and safety of Hydroxysafflor Yellow A for Injection (HSYAI) in treating patients with acute ischemic stroke (AIS) and blood stasis syndrome (BSS).

Methods: A multicenter, randomized, double-blind, multiple-dose, active-controlled phase II trial was conducted at 9 centers in China from July 2013 to September 2015. Patients with moderate or severe AIS and BSS were randomly assigned to low-, medium-, high-dose HSYAI groups (25, 50 and 70 mg/d HSYAI by intravenous infusion, respectively), and a control group (Dengzhan Xixin Injection (, DZXXI) 30 mL/d by intravenous infusion), for 14 consecutive days.

Biocompatiable silk fibroin/carboxymethyl chitosan/strontium substituted hydroxyapatite/cellulose nanocrystal composite scaffolds for bone tissue engineering.

Bone defects arise from trauma, skeletal diseases or tumor resections have become a critical clinical challenge. Biocomposite materials as artificial bone repair materials provide a promising approach for bone regeneration. In this study, we used silk fibroin (SF), carboxymethyl chitosan (CMCS), cellulose nanocrystals (CNCs) and strontium substituted hydroxyapatite (Sr-HAp) to prepare the biocomposite scaffolds of SF/CMCS, SF/CMCS/CNCs, SF/CMCS/CNCs/Sr-HAp.

Genetic variability of ERCC1 and ERCC2 genes involved in the nucleotide excision repair pathway influences the treatment outcome of gastric cancer.

We conducted a prospective study to investigate whether ERCC1 rs11615 and rs3212986 and ERCC2 rs13181 and rs1799793 gene polymorphisms could serve as potential biomarkers for the prognosis of gastric cancer. Between January 2010 and December 2012, 246 patients with pathologically proven gastric cancer who were receiving platinum-based chemotherapy were recruited from the First Affiliated Hospital of Guangxi Medical University. The genotyping of the gene polymorphisms was conducted using the polymerase chain reaction coupled with restriction fragment length polymorphism.

Association between the C.1161G>A and C.1779C>G genetic variants of XRCC1 gene and hepatocellular carcinoma risk in Chinese population.

The human X-ray repair complementing group 1 gene (XRCC1) is an important candidate gene influencing hepatocellular carcinoma (HCC) susceptibility. The objective of this study was to detect the association between c.1161G>A and c.
