Accelerated crystallization of magnetic 4A-zeolite synthesized from red mud for application in removal of mixed heavy metal ions.

To cope with the increasing environmental issues of red mud, an integrated technological route for its comprehensive utilization was developed through the extraction of valuable components and the synthesis of magnetic 4A-zeolite. To accelerate the crystallization process of the synthesized 4A-zeolite, sodium chloride (NaCl) was innovatively employed under hydrothermal treatment. The effects of various parameters, including mass ratio of red mud/NaOH, alkali fusion temperature, alkali fusion time and molar ratio of NaCl/AlO, were systematically investigated.

[Regulatory effect of compound Coptidis Rhizoma capsule on unbalanced expression of renal tissue TGF-β1/BMP-7 and Smad signaling pathway in rats with early diabetic nephropathy].

Objective: To investigate the effect of compound Coptidis Rhizoma capsule (CCRC) on unbalanced expression of renal tissue TGF-β1/BMP-7 and Smad signaling pathway in rats with early diabetic nephropathy (DN), and discuss CCRC's effect on DN rats with early diabetic nephropathy and its possible mechanism.

Method: DN model rats were established by injecting streptozotocin (STZ). The rats were randomly divided into seven groups: the normal group, the model group, the enalapril treatment group, the xiaoke pill treatment group and three CRCC treatment groups.

[Regulatory effect of berberine on unbalanced expressions of renal tissue TGF-beta1/SnoN and smad signaling pathway in rats with early diabetic nephropathy].

Objective: To investigate the effect of berberine (BBR) on unbalanced expression of renal tissue TGF-beta1/SnoN and Smad signal pathway in rats with early diabetic nephropathy (DN), and discuss BBR's effect on DN rats with early diabetic nephropathy and its possible mechanism.

Method: DN rat model were established by injecting streptozotocin (STZ). The rats were divided into six groups: the control group, the model group, three BBR (50, 100, 200 mg x kg(-1)) treatment groups and the enalapril treatment group.

[Effect of compound Rhizoma Coptidis capsule on expression of transforming growth factor-beta1 and type IV collagen proteins in renal tissue of diabetic rats with nephropathy].

Objective: To explore the effect and mechanism of compound Rhizoma Coptidis capsule (CRCC) on diabetic nephropathy in experimental rats.

Method: The rat model of early diabetic nephropathy was induced by injection of streptozotocin (STZ). The rats were divided into 6 groups: normal control group, model group, 3 CRCC treatment groups and XKW treatment group.
