RTA-408 Regulates p-NF-κB/TSLP/STAT5 Signaling to Ameliorate Nociceptive Hypersensitivity in Chronic Constriction Injury Rats.

Neuropathic pain following nerve injury is a complex condition, which often puts a negative impact on life and remains a sustained problem. To make pain management better is of great significance and unmet need. RTA 408 (Omaveloxone) is a traditional Asian medicine with a valid anti-inflammatory property. Thus, we aim to investigate the therapeutic effect of RTA-408 on mechanical allodynia in chronic constriction injury (CCI) rats as well as the underlying mechanisms. Neuropathic pain was induced by using CCI of the rats' sciatic nerve (SN) and the behavior testing was measured by calibrated forceps testing. Activation of Nrf-2, the phosphorylation of nuclear factor-κB (NF-κB), and the inflammatory response were assessed by western blots. The number of apoptotic neurons and degree of glial cell reaction were examined by immunofluorescence assay. RTA-408 exerts an analgesic effect on CCI rats. RTA-408 reduces neuronal apoptosis and glial cell activation by increasing Nrf-2 expression and decreasing the inflammatory response (TNF-α/ p-NF-κB/ TSLP/ STAT5). These data suggest that RTA-408 is a candidate with potential to reduce nociceptive hypersensitivity after CCI by targeting TSLP/STAT5 signaling.

Observation of Curative Effect of Trimetazidine Combined with Metoprolol in Elderly Patients with Coronary Heart Disease Complicated with Heart Failure and the Effect of Myocardial Remodeling by Integrated Traditional Chinese and Western Medicine.

Diabetic retinopathy (DR) is the most common complication of diabetes and is often characterized by damage to retinal vascular microcirculation, resulting in retinal exudation, hemorrhage, fibrosis, and neovascularization. With the aging of my country's population, the incidence of DR is increasing year by year, and it has become one of the main blinding eye diseases in ophthalmic diseases also tends to be younger. So far, although the pathogenesis of DR is not completely clear, scholars generally believe that DR is based on the disorder of glucose metabolism, causing changes in the microcirculation of ocular tissues, nerves, and blood vessels, resulting in chronic damage to the nutrition and visual function of the eye disease. In order to explore the demand for cardiovascular disease treatment, make up for the lack of chronic diseases affecting people's physical harm, and improve the success rate of cardiovascular disease treatment, a method to observe the efficacy and myocardial remodeling of trimetazidine combined with metoprolol in elderly patients with coronary heart disease and heart failure based on integrated traditional Chinese and Western medicine was proposed. 54 elderly people over 60 years old are afraid of cardiovascular disease and take active protection. A method based on observation of integrated traditional Chinese and Western medicine was proposed, and at the same time, an intelligent medical monitoring system was constructed to better study, observe, and improve the efficacy of trimetazidine combined with metoprolol in elderly patients with coronary heart disease, heart failure, and myocardial impact of refactoring. The results of the study show that trimetazidine has a good clinical effect on ischemic cardiomyopathy heart failure based on the observation of integrated traditional Chinese and Western medicine.

Hyperpigmentation as a peculiar presentation of mycosis fungoides.

Hyperpigmented mycosis fungoides is an extremely rare subtype of mycosis fungoides. It presents as multiple pigmented macules and patches without poikilodermatous changes and characterized by a CD8+ phenotype on immunohistochemistry. This report describes a typical case of hyperpigmented mycosis fungoides in a 62-year-old woman, who presented with a 7-year history of multiple hyperpigmented macules and patches on the trunk and right leg with progression over this half a year. Histology and immunohistochemical staining of skin samples confirmed the diagnosis of mycosis fungoides. She received psoralen plus ultraviolet A (PUVA) therapy. After an 8-week treatment, the erythematous changes cleared without recurrence during a 6-month follow-up period. An intractable hyperpigmented patch should raise the clinical suspicion of mycosis fungoides with sequential skin biopsy.

Hypocalcemia and tetany caused by vitamin D deficiency in a child with intestinal lymphangiectasia.

Primary intestinal lymphangiectasia is a rare disease of children, which is characterized by chronic diarrhea and complicated with malnutrition, including fat-soluble vitamin deficiency. We report a girl aged 4 years and 8 months who was diagnosed with the disease by endoscopic duodenal biopsy at 8 months of age. She presented initially with chronic diarrhea at 4 months of age. Generalized edema with hypoalbuminemia frequently occurred despite regular albumin supplements. Multiple vitamins initially were not supplied regularly. Episodes of tetany caused by hypocalcemia developed 4 years after the diagnosis of intestinal lymphangiectasia. Imaging study (long-bone X-ray and dual-energy X-ray absorptiometry) revealed low bone density. Complicated vitamin D deficiency [low serum 25-hydroxy vitamin D concentration (< 12.48 mmol/L, the detection limit)] and secondary hyperparathyroidism were confirmed via blood testing. Vitamin D supplementation for 3 months improved her bone density, secondary hyperparathyroidism and frequent tetany. Vitamin D status should be monitored in patients with intestinal lymphangiectasia.
