Lanthanum Hydroxide and Chronic Kidney Disease Mineral and Bone Disorder: A Rat Model.

Objective: To investigate the pharmacological effects and molecular mechanisms of lanthanum hydroxide(LH) on ectopic mineralization of soft tissue and abnormal bone in rats with acute kidney injury(AKI).

Methods: Wistar rats were modeled by 5/6 nephrectomy. After the operation, the rats were divided into different groups, the biochemical indexes of serum collected at different times.

Metabolomics of clinical samples reveal the treatment mechanism of lanthanum hydroxide on vascular calcification in chronic kidney disease.

Previous studies showed that lanthanum hydroxide (LH) has a therapeutic effect on chronic kidney disease (CKD) and vascular calcification, which suggests that it might have clinical value. However, the target and mechanism of action of LH are unclear. Metabolomics of clinical samples can be used to predict the mechanism of drug action.

Lanthanum hydroxide inhibits vascular calcification by regulating the HIF-1 pathway.

The main reason for the high incidence of cardiovascular disease in chronic kidney disease (CKD) patients with vascular calcification (VC) is also the main cause of death in CKD patients. Lanthanum hydroxide (LH) has an inhibitory effect on VC in chronic renal failure; however, the mechanism of its inhibition is poorly defined. Here, we used network pharmacology analysis and found that hypoxia-inducible factor (HIF) is related to VC.

The Impact of the SARS-COV-2 Pandemic on the Mental Health and Employment Decisions of Medical Students in North China.

The outbreak of severe respiratory syndrome coronavirus 2 (SARS-COV-2) has led to long periods of social isolation for individuals across the world. Although medical students generally have a high prevalence of mental health problems, they have received less attention than other groups concerning the impact of SARS-COV-2. Therefore, the present study investigated the mental health status, risk factors, and protective factors for mental health problems in medical students in North China during the SARS-COV-2 pandemic.

The Pharmacological Effect and Mechanism of Lanthanum Hydroxide on Vascular Calcification Caused by Chronic Renal Failure Hyperphosphatemia.

Objective: The present work aimed to explore the efficacy of lanthanum hydroxide in managing the vascular calcification induced by hyperphosphate in chronic renal failure (CRF) as well as the underlying mechanism.

Methods: Rats were randomly allocated to five groups: normal diet control, CKD hyperphosphatemia model, CKD model treated with lanthanum hydroxide, CKD model receiving lanthanum carbonate treatment, together with CKD model receiving calcium carbonate treatment. The serum biochemical and kidney histopathological parameters were analyzed.

[Characteristics of Robinia pseudoacacia water physiological ecology under different habitats in North Shaanxi gully areas of Loess Plateau].

With locust (Robinia pseudoacacia), the main tree species in afforestation, as test material, this paper studied the characteristics of its water physiological ecology and productivity under four habitats, i. e. , sunny, shady, semi-sunny and semi-shady hillsides, in the North Shaanxi gully areas of Loess Plateau.
