Autophagy-related lncRNAs and exosomal lncRNAs in colorectal cancer: focusing on lncRNA-targeted strategies.

Autophagy is a cellular process that involves the degradation and recycling of cellular components, including damaged proteins and organelles. It is an important mechanism for maintaining cellular homeostasis and has been implicated in various diseases, including cancer. Long non-coding RNAs (lncRNAs) are a class of RNA molecules that do not code for proteins but instead play regulatory roles in gene expression.

Effect of hip replacement surgery on clinical efficacy, VAS score and Harris hip score in patients with femoral head necrosis.

Aim: To study the effect of hip replacement surgery on the clinical treatment efficacy, VAS score and Harris hip score of patients with necrosis of the femoral head (NFH). A total of 86 patients with NFH who were treated in our hospital from January 2016 to January 2019 were selected as the research subjects, and were divided into the control group (n = 43, conventional artificial hip replacement) and the observation group (n = 43, modified version of artificial hip replacement) according to a random number table method. The treatment efficacy, pain, hip function, motor function and adverse reactions of the two groups were compared.

Glaucocalyxin B protects against oxygen-glucose-deprivation/reperfusion-induced neuronal injury in PC-12 cells.

Oxidative stress has been implicated in the development of cerebral ischemia/reperfusion (I/R) injury. Glaucocalyxin B (GLB), one of five ent-kauranoid diterpenoids, was reported to possess neuroprotective activity. However, the effect of GLB on oxygen-glucose-deprivation/reperfusion (OGD/R)-induced cell injury in PC-12 cells has not been explored.

[Effect of hyperforin on learning and memory abilities and Aβ₁₋₄₂, βAPP and BACE1 protein expressions in hippocampus of Alzheimer's disease model mice].

To investigate the effect of the hyperforin (HF) on learning and memory function and Aβ₁₋₄₂, βAPP and BACE1 protein expressions in hippocampus of five-month-old APP/PS1 double transgenic mice, and discuss the underlying mechanism of HF. The five-month-old APP/PS1 double transgenic mice were randomly divided into the model group, rosiglitazone group (12 mg•kg⁻¹•d⁻¹) and HF high dose, middle dose and low dose groups (600, 300 and 150 mg•kg⁻¹•d⁻¹) in each group; in addition, 15C57BL/6J mice with the same months and background were selected as normal group. Drugs were diluted in the same volume before using, and then administrated by ig for 7 months, 1 time a day; the mice in normal group and model group received the same volume of distilled water.

[Preparation of sinomenine hydrochloride delayed-onset sustained-release tablets].

Objective: To prepare sinomenine hydrochloride delayed-onset sustained-release tablets.

Method: The tablets containing sinomenine hydrochloride were prepared by dry-compression coating technique with the ratio of HPMC in core tablet and the ratio of HPMC in coating film as the influence factors and the lag-time and release rate as the evaluation parameters. Experiments were done on the central composite design, the data were simulated by using multi-linear equation and second-order polynomial equation.

[Preparation of gastric retenting and chronopharmacologic drug delivery tablets of sinomenine hydrochloride].

Objective: To prepare the gastric retenting and chronopharmacologic drug delivery tablets containing sinomenine hydrochloride as a model drug, evaluate the effects of the coating layers formulation and technics on drug release behavior, and to elucidate the mechanism of drug release based on obtained results.

Method: The gastric retenting and chronopharmacologic drug delivery tablets were prepared by press-coated technics. The types of disintegrants were chosen according to the expanding rate and the lag-time.
