Development and validation of prediction model for stage I patients with lower extremity atherosclerotic disease in type 2 diabetes mellitus in China.

Aims: Lower extremity atherosclerotic disease (LEAD) is the primary cause of ulcers, gangrene, and amputations in patients with type 2 diabetes mellitus (T2DM), stage I is the crucial time for prevention and intervention to improve the prognosis of T2DM-LEAD. The purpose of this study was to develop and validate a personalized predictive model to determine the risk of outcomes in stage I patients with T2DM-LEAD.

Methods: There were 1603 stage I patients with T2DM-LEAD at baseline in this retrospective study.

Bioinformatics and Experimental Analyses Reveal MAP4K4 as a Potential Marker for Gastric Cancer.

Background: Gastric cancer remains the most prevalent and highly lethal disease worldwide. MAP4K4, a member of Ste20, plays an important role in various pathologies, including cancer. However, its role in gastric cancer is not yet fully elucidated.

Integrated traditional Chinese medicine intervention for delaying HIV morbidity: study protocol for a multicentre randomised controlled trial.

Background: Acquired immune deficiency syndrome is caused by humans and is high worldwide. Active antiretroviral therapy emerged in the late 1990s and is effective against AIDS. However, despite the extensive research on AIDS, there is still no vaccine or cure.

Electrochemical Immunoassay for Tumor Marker CA19-9 Detection Based on Self-Assembled Monolayer.

A CA19-9 electrochemical immunosensor was constructed using a hybrid self-assembled membrane modified with a gold electrode and applied to detect real samples. Hybrid self-assembled membranes were selected for electrode modification and used to detect antigens. First, the pretreated working electrodes were placed in a 3-mercaptopropionic acid (MPA)/β-mercaptoethanol (ME) mixture for 24 h for self-assembly.

Evodiamine decreased the systemic exposure of pravastatin in non-alcoholic steatohepatitis rats due to the up-regulation of hepatic OATPs.

Context: Patients with non-alcoholic steatohepatitis (NASH) may have a simultaneous intake of pravastatin and evodiamine-containing herbs.

Objective: The effect of evodiamine on the pharmacokinetics of pravastatin and its potential mechanisms were investigated in NASH rats.

Materials And Methods: The NASH model was conducted with feeding a methionine choline-deficient (MCD) diet for 8 weeks.

Rutaecarpine enhances the anti-diabetic activity and hepatic distribution of metformin via up-regulation of Oct1 in diabetic rats.

Diabetes mellitus is a chronic metabolic disorder with multiple complications, patients who receive metformin may have a simultaneous intake of herbal medicine containing rutaecarpine due to cardiovascular protection and hypolipidemic effects of rutaecarpine. There might be drug interactions between metformin and rutaecarpine. This study aimed to investigate the effects of rutaecarpine on the pharmacodynamics and pharmacokinetics of metformin in diabetic rats.

Involvement of organic anion-transporting polypeptides and organic cation transporter in the hepatic uptake of jatrorrhizine.

Jatrorrhizine possesses a wide spectrum of pharmacological activities. However, the mechanism underlying hepatic uptake of jatrorrhizine remains unclear.Rat liver slices, isolated rat hepatocytes and human embryonic kidney 293 (HEK293) cells stably expressing human organic anion-transporting polypeptide (OATP) and organic cation transporter (OCT) were used to evaluate the hepatic uptake of jatrorrhizine in this study.

[Effect of Saposhnikoviae Radix on pharmacokinetics and tissue distributions of active components in Tongxie Yaofang in rats].

Tongxie Yaofang (TXYF) is a famous formula that has been used for treating gastrointestinal diseases in traditional Chinese medicine(TCM). Saposhnikoviae Radix is considered as a meridian guiding drug in TXYF and could enhance the effectiveness of prescription. However, the scientific evidence for this effect is still not clear.

Early Activation of PINCH/ Glycogen-Synthase Kinase 3β/ERK Pathway in Obstructive Nephropathy Rat Model.

Background: Despite a previous study showing that PINCH-1 exerts an important role in regulating TGF-β1-mediated mesenchymal transition through its interaction with integrin-linked kinase, relatively little is known about the role of PINCH in the obstructive nephropathy.

Methods: To construct a rat model of renal interstitial fibrosis and obstructive nephropathy, unilateral ureteral obstruction (UUO) was used. Hematoxylin and eosin and Masson staining were used in histologic examinations.
