Monomorphic epitheliotropic intestinal T-cell lymphoma with bone marrow involved: A case report.

BACKGROUND: Monomorphic epithelial intestinal T-cell lymphoma (MEITL) is a rare type of peripheral T-cell lymphoma. The clinical manifestations are diarrhea, abdominal pain, perforation and an abdominal mass. CASE SUMMARY: We present a 52-year-old female patient who was diagnosed with MEITL. Further disease progression was observed after multiline chemotherapy. Eventually, the patient died of a severe infection. CONCLUSION: MEITL is a rare intestinal primary T-cell lymphoma with aggressive behavior, a high risk of severe life-threatening complications, and a poor prognosis.

Research progress of clinical intervention and nursing for patients with post-stroke dysphagia.

Post-stroke dysphagia (PSD) is a common and costly complication of stroke and is associated with increased mortality, morbidity, and hospitalization. Although most patients can spontaneously resume swallowing, there are still many patients who do not recover and even die. Despite multiple advances in the acute treatment and secondary prevention of stroke, the effective treatment of PSD remains a neglected area. Studies have shown that repair mechanisms of neurostimulation techniques and increased cortical activity play an important role in the treatment of PSD. In addition, nutritional interventions are also crucial for the treatment of malnutrition in PSD patients. Therefore, this article reviews the effects of the current main clinical treatment methods and nutritional interventions on the treatment and rehabilitation of PSD patients. It also emphasized the necessity of developing an individualized care plan for PSD patients, which is of great significance to promote the clinical treatment, nutritional status, prognosis, and quality of life of PSD patients.

Regulation of Sirt1 on energy metabolism and immune response in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a systemic autoimmune disease. Synovial hyperplasia and persistent inflammation serve as its typical pathological manifestations, which ultimately lead to joint destruction and function loss. Both clinical observations and metabolomics studies have revealed the prevalence of metabolic disorders in RA. In inflammatory immune microenvironments, energy metabolism is profoundly changed. Increasingly evidences suggest that this abnormality is involved in the occurrence and development of RA-related inflammation. Unsurprisingly, many energy metabolism sensors have been confirmed with immunoregulatory properties. As a representative, silent information regulator type 1 (Sirt1) controls many aspects of immune cells, such as cell lifespan, polarization, and secretion by functioning as a transcriptional regulator. Because of the profound clinical implication, researches on Sirt1 in the regulation of energy metabolism and immune functions under RA conditions have gradually gained momentum. This signaling balances glycolysis, lipid metabolism and insulin secretion orchestrating with other metabolism sensors, and consequently affects immune milieu through a so-called metabolism-immune feedback mechanism. This article reviews the involvement of Sirt1 in RA by discussing its impacts on energy metabolism and immune functions, and specially highlights the potential of Sirt1-targeting anti-rheumatic regimens. It also provides a theoretical basis for clarifying the mystery about the high incidence of metabolic complications in RA patients and identifying new anti-rheumatic reagents.

[Identification of effective components from Naoxintong Capsules intestinal absorption liquid in inhibiting ADP-induced platelet aggregation].

Intestinal absorption liquid was prepared by using everted intestinal sac method; meanwhile, its recipes were decomposed or restructured. Platelet aggregation activity was examined by biochemical tests and a microplate reader. One or more kinds of Chinese medicines which displayed inhibiting activity in Naoxintong Capsules were screened through separation and combination of prescription. The results showed that Naoxintong Capsules could inhibit ADP-induced platelet aggregation. Recipe decomposition and restructuring results showed that Salviae Miltiorrhizae Radix et Rhizoma, Paeoniae Radix Rubra, Cinnamomi Ramulus and Hirudo were the main effective medicines in inhibiting platelet aggregation. Furthermore, Cinnamomi Ramulus played a vital role in inhibiting activity among those four kinds of Chinese medicines. Coumarin derived from intestinal absorption liquid of Cinnamomi Ramulus had inhibiting activity in the range of 50-200 µmol·L⁻¹, and other ingredients such as cinnamyl alcohol and cinnamaldehyde also had inhibiting activities. In conclusion, Salviae Miltiorrhizae Radix et Rhizoma, Paeoniae Radix Rubra, Cinnamomi Ramulus and Hirudo are the main components for inhibiting ADP-induced platelet aggregation, and Cinnamomi Ramulus has the most strongest inhibiting activity in Naoxintong Capsules.

[The experimental study of Radix Puerariae inhibiting glycation in rats induced by D-galactose].

OBJECTIVE: To observe the effects of Radix Puerariae on protein glycation in model rats induced by D-galactose. METHODS: The model rats of protein glycatin were induced by intraperitoneal administration of D-galactose (150 mg/kg) for 8 weeks, and all rats were treated by Radix Puerariae (High dose 300 mg/kg, Middle dose 150 mg/kg, Low dose 75 mg/kg) for 6 weeks. The activity of aldose reductase in red blood cells, the content of fructosamine in serum, the amount of glycohaemoglobin and advanced glycation end-products, the level of insulin in serum, the activity of superoxide dismutase and the amount of maleic dialdehyde were measured. RESULTS: High dose and middle dose of Radix Puerariae could decrease the level of blood glucose and the activity of aldose reductase in red blood cells, inhibit the formation of glycation products significantly in model rats induced by D-galactose (P < 0.01), increase insulin sensitivity and activity of superoxide dismutase (P < 0.01) and decrease the amount of maleic dialdehyde (P < 0.01). CONCLUSION: Puerariae can significantly inhibit glycation reaction in rats induced by D-galactose.
