Embodiment 1

[0023] Embodiment 1: The impact of ibuprofen on the cognitive function of DM rats

[0024] 1 Materials and methods

[0025] 1.1 Experimental animals

[0026] Male SD strain rats, 8-9 weeks old, 190-220g, were provided by the Experimental Animal Center of Xuzhou Medical College.

[0027] 1.2 Drugs and reagents

[0028] Ibuprofen was purchased from Wuhan Huayida Technology Co., Ltd. (purity>99%), STZ was purchased from Sigma-Aldrich Company of the United States, and the glucose test box was purchased from Nanjing Jiancheng Bioengineering Institute.

[0029] 1.3 Method

[0030] 1.3.1 Model establishment Male SD rats were fasted for more than 12 hours, and STZ (dissolved in 0.1 mol / L sodium citrate buffer, pH 4.4 before use) was injected intraperitoneally at 60 mg / kg to establish the model. Seven days after modeling, about 0.2 ml of blood was collected from the orbital venous plexus, centrifuged at 25°C and 3000 rpm for 10 min, and the serum was separated. Non-fasting blood...

Embodiment 3

[0085] Example 3: Effects of ibuprofen on apoptosis and necrosis of hippocampal neurons in the brain of DM rats

[0086] 1 Materials and methods

[0087] 1.1 Experimental animals Same as Example 1.

[0088] 1.2 Drugs and reagents Conventional HE staining reagents were provided by the Department of Pathology, Xuzhou Medical College.

[0089] 1.3 Method

[0090] The apoptosis and necrosis of hippocampal neurons in the brain of DM rats were observed under light microscope by HE staining. The preserved wax blocks were cut into 3 μm thick sections for routine HE staining. HE staining of rat brain sections was commissioned to the Department of Pathology, Xuzhou Medical College.

[0091] 2 results

[0092] The results of HE staining in the CA1 region of the rat hippocampus showed that in the normal group: 3-5 layers of pyramidal cells neatly arranged were observed, the cell shape was normal, and the nucleus was in the middle; in the DM group: the number of pyramidal cells was ...

Abstract

The invention provides novel pharmacologic action of non-steroidal anti-in-flammatory medicines, i.e. the action for preventing and treating the diabetic encephalopathy. The non-steroidal anti-inflammatory medicines (ibuprofen) can be used for obviously improving the injury of the cognitive function caused by the diabetes mellitus, obviously increasing the protein expression and the mRNA (messenger ribose nucleic acid) level of intracerebral peroxisome proliferators-activated receptor gamma (PPAR gamma), obviously reducing the activity, the protein expression and the mRNA level of cerebral cortex beta amyloid precursor protein gamma-beta amyloid cleaving enzyme 1 (beta amyloid cleaving enzyme 1), the level of end-stage advanrced glycation end products (AGEs), and the protein expression of cyclo-oxygenase 2 (COX-2) and inducible nitric oxide synthase (iNOS), and obviously increasing the level of superoxide dismutase (SOD) reduced glutathione (GSH) in blood serum, etc. The non-steroidal anti-in-flammatory medicines can be used for preventing and treating the diabetic complication, i.e. the diabetic encephalopathy.

Description

technical field [0001] The invention relates to a new application of non-steroidal anti-inflammatory drugs, in particular to the application of non-steroidal anti-inflammatory drugs in the prevention and treatment of diabetic encephalopathy. Background technique [0002] Diabetic encephalopathy (Diabetic encephalopathy, DE) refers to the gradual occurrence of long-term diabetes mellitus (DM) patients with mental disorders characterized by mental decline and brain neurophysiological and structural changes. Most common complication. In the state of diabetes, the structural changes of the brain are mainly the cerebral cortex and cortical atrophy, and the functional changes are mainly the impairment of cognitive function. A large number of research reports have confirmed the fact that diabetes causes cognitive dysfunction. In 2006, the introduction of the term diabetes-associated cognitive decline (DACD) further enhanced people's understanding of this dysfunction and became the...
