BACKGROUND:Animal models of diabetic encephalopathy that have been studied mainly include streptozotocin-induced model,high-sugar and high-fat diet-induced model and spontaneous animal model.Establishing a simple,easy,short-cycle,safe and effective model of diabetic encephalopathy can help to explore the subsequent pathogenesis and screen therapeutic drugs. OBJECTIVE:To further explore and evaluate the method of building diabetic encephalopathy rat models. METHODS:Twenty Sprague-Dawley rats were randomly divided into control(n=10)and model(n=10)groups.Rats in the model group were given a single injection of 45 mg/kg streptozotocin in the left lower abdominal cavity,and those in the control group were given the same amount of citrate buffer.During the experiment,the body mass,feed intake,water intake and blood glucose were measured.After 8 weeks,the glucose tolerance and oxidative stress levels were measured,and the pathological changes of brain tissue and the expression of apoptotic proteins were compared between groups. RESULTS AND CONCLUSION:Compared with the control group,the food intake,water intake,encephalization quotient,blood glucose and area under the blood glucose curve were significantly increased in the model group,while the body mass decreased significantly(P<0.01).Histopathological examination of the brain showed that compared with the control group,the number of surviving nerve cells was significantly reduced in the model group(P<0.01),with more significant pathological damage of nerve cells.Compared with the control group,the activities of serum superoxide dismutase,catalase and glutathione in the model group were significantly decreased(P<0.01),and the content of oxidative malondialdehyde was significantly increased(P<0.05).The expression levels of apoptosis-related proteins Bax and Caspase-3 in brain tissue increased in the model group compared with the control group,while the expression of Bcl-2 decreased(P<0.01).In conclusion,an 8-week injection of 45 mg/kg streptozotocin can cause obvious pathological damage to the brain tissue of diabetic rats,to successfully establish the rat model of diabetic encephalopathy.

This article introduced Professor Wang Xingkuan's academic thoughts and clinical experience in diagnosing and treating burning mouth syndrome(BMS)in perimenopausal women based on the theory of"yin injury and internal dryness".Professor Wang advocates the principle of"treating the root cause of the disease and harmonizing multiple organs".Starting from the unique physiological characteristics of perimenopausal women,he believes that the BMS in perimenopausal women should be attributed to the kidneys,liver,heart,and small intestine.The fundamental cause of the disease is the deficiency of kidney essence and the gradual decline of liver blood,and the key to the onset is the dryness of the kidney,liver,heart,and small intestine.In treatment,the overall strategy is to take"yin injury and internal dryness"as the main guideline,focusing on the liver and kidney,with nourishing and replenishing the liver and kidney as the main approach and clearing heat and moistening as auxiliary methods.The basic formula for treating BMS is a combination of Erdong Decoction and Baihe Dihuang Decoction,which has shown significant clinical efficacy.

Background: Heart failure (HF) is the leading cause of death worldwide. Myocardial infarction (MI) is a major contributor to HF. Shengmai injection (SMI) has exhibited protective efficacy in preventing HF. However, the advantages of SMI in the progression of MI-induced HF remain unclear. Objective: To reveal the advantages of SMI in the progression of MI-induced HF. Methods: The differently expressed proteins in rat models with ischemia at the 7th, 14th, 21st, and 28th days were obtained from PubMed. The “compound-target” network of SMI was constructed via the Bioinformatics Analysis Tool for Molecular mechANism of Traditional Chinese Medicine database. The protein-protein interaction relationship was constructed, and biological function was applied to evaluate the advantage effect of SMI in the progression of MI-induced HF. In addition, the prediction results were validated in rats with left anterior descending coronary artery ligation. The cardiac function and heart performance were observed via echocardiography, hematoxylin-eosin staining, and Masson staining, and the levels of procollagen type I carboxy-terminal propeptide, recombinant versican (VCAN), and collagen 1A1 (COL1A1) weremeasured via enzyme-linked immunosorbent assay in rat plasma. In vitro, H9c2 cells were treated with Angiotensin II (Ang II), and the cell viability, the level of reactive oxygen species (ROS) and Ca
, and the expression of ANP and connective tissue growth factor were evaluated. Furthermore, the schizandrin A was identified as one of the possible key compounds. After schizandrin A treatment, the level of ROS and Ca
and the expression of COL1A1 and VCAN were evaluated. Results: There were 189 compounds and 1612 targets involved in the “compound-target” network, and an interaction relationship was constructed. According to the top subnetwork, the Gene Ontology annotation revealed that SMI may have an antifibrotic and cardiac protective effect against MI-induced HF. In rats, SMI increased ejection fraction, left ventricular fractional shortening, and cardiac output and decreased fibrosis injury; moreover, SMI decreased the levels of procollagen type I carboxy-terminal propeptide, VCAN, and COL1A1 within 35 days. When compared with the Ang II treatment group, SMI increased cell viability and decreased cellular calcium concentration, ROS generation, and the expression of ANP and connective tissue growth factor in vitro. Furthermore, schizandrin A was discovered to be a possible compound in myocardial protection. Schizandrin A increased cell viability after Ang II treatment while decreasing COL1A1 and VCAN levels. Conclusions: This method demonstrates that SMI has an antifibrotic effect. This study provides a promising perspective on translating omics data to clinical applications, as well as an appealing approach to investigating the precise intervention of a multicomponent drug.

Objective:To observe the relationship between inducible carbon monoxide synthase (iNOS) and delayed encephalopathy after acute carbon monoxide poisoning (DEACMP), and explore its mechanism of action in DEACMP.Methods:This study was designed as prospective cohort study. Patients with acute carbon monoxide poisoning who met the diagnostic criteria and were admitted to Emergency Intensive Care Unit(EICU) of our hospital from June 2019 to June 2021 were selected as subjects. Patients were divided into the DEACMP group and non-DEACMP group according to the occurrence of DEACMP. Serum samples were collected on the first 24 h after admission and on day 7 and 14 after admission, and the serum nitric oxide (NO), neuronal nitric oxide synthase (nNOS), inducible carbon monoxide synthase (iNOS), and endothelial nitric oxide synthase (eNOS) level were measured by enzyme-linked immunosorbent assay. The generalized estimating equation was used to estimate the difference of NO, nNOS, iNOS and eNOS between DEACMP and non-DEACMP patients.Results:A total of 78 patients with carbon monoxide poisoning were included in our study finally, including 49 (62.82%) males and 29 (37.18%) females, with an average age of (53.96±14.95) years, 20 (25.64%) patients with DEACMP, and 1 (1.28%) death. Univariate analysis showed that patients with DEACMP had an average increase of 3 h (95% CI: 1.00, 5.00) in carbon monoxide exposure time and a 5-point decrease in GCS score (95% CI: 1.00, 6.00) than the patients without DEACMP, and the proportion of patients with severe carbon monoxide poisoning in the DEACMP group was higher than that of the non-DEACMP group (90.00% vs. 32.76%). According to the analysis of generalized estimation equation, on day 7 and 14 after admission, Compared with non-DEACMP patients, neither by performing unadjusted nor adjusted analysis with the iNOS of DEACMP patients was significantly higher than that in non-DEACMP patients regardless of whether exposure time, GCS score, coma time or severity of carbon monoxide poisoning were adjusted or not ( P <0.01 or P <0.05). Except for the level of nNOS in the GEE model adjusted with carbon monoxide exposure time, the levels of NO, nNOS and eNOS showed no significant difference between DEACMP and non-DEACMP patients ( P >0.05). Conclusions:The expression of iNOS level is increased in DEACMP patients, and its continuous expression may be involved in the pathogenesis of DEACMP.
