Polygonum multiflorum stilbeneglycoside (PMS) is a water-soluble fraction of Polygonum multiflorum Thunb. , one of the most famous tonic traditional Chinese medicines, that has protective effects on the cardiovascular system. The purpose of the present study is to elucidate the effects of PMS on macrophage-derived foam cell functions and the reduction of severity of atherosclerosis in hypercholesterolemic New Zealand White (NZW) rabbits. NZW rabbits were fed for 12 weeks with a normal diet, a high cholesterol diet, or a high cholesterol diet associated with irrigation with different doses of PMS (25, 50, or 100 mg/kg). Treatment of NZW rabbits fed with high cholesterol diet with 100 mg/kg PMS attenuated the increase in plasma cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, and plasma triglyceride. Treatment with 50 and 100 mg/kg PMS caused 43% and 60% decrease in atherosclerotic lesioned area ratio to total surface area, respectively. In U937 foam cells, PMS could decrease the high expression of intercellular adhesion molecule (ICAM)-1 protein and the vascular endothelial growth factor (VEGF) protein levels in the medium induced by oxidized lipoprotein when analyzed by flow cytometry. The results proved that PMS is a powerful agent against atherosclerosis and that PMS action could possibly be through the inhibition of the expression of ICAM-1 and VEGF in foam cells. 相似文献

Complications from improperly placed biliary stents are not uncommon. Free loose wires from the ends of an uncovered stent can irritate and damage adjacent mucosal surfaces. Effective management can be achieved via percutaneous placement of a second stent to alter the orientation of the original stent. 相似文献

Ionising radiation therapy is a common treatment modality for different types of cancer and its use is expected to increase with advances in screening and early detection of cancer.Radiation injury to the gastrointestinal tract is important factor working against better utility of this important therapeutic modality.Cancer survivors can suffer a wide variety of acute and chronic symptoms following radiotherapy,which significantly reduces their quality of life as well as adding an extra burden to the cost of health care.The accurate diagnosis and treatment of intestinal radiation injury often represents a clinical challenge to practicing physicians in both gastroenterology and oncology.Despite the growing recognition of the problem and some advances in understanding the cellular and molecular mechanisms of radiation injury,relatively little is known about the pathophysiology of gastrointestinal radiation injury or any possible susceptibility factors that could aggravate its severity.The aims of this review are to examine the various clinical manifestations of post-radiation gastrointestinal symptoms,to discuss possible patient and treatment factors implicated in normal gastrointestinal tissue radiosensitivity and to outline different mechanisms of intestinal tissue injury. 相似文献

Natural Abs and autoantibodies bind antigens displayed by ischemia-conditioned tissues, followed by complement activation and enhanced tissue injury during reperfusion. Anti-ribonucleoprotein (RNP) Ab is associated with lung disease in patients with autoimmune disease but it is not known whether these abs contribute to lung injury. Mesenteric I/R in mice leads to local and remote lung injury. Accordingly, we used this model to investigate whether anti-RNP Abs would reconstitute I/R damage with prominent lung damage in injury-resistant Rag1? / ? animals. Rag1? / ? mice injected with anti-RNP Ab containing serum and subjected to mesenteric I/R suffered greater intestinal injury than control-treated and sham-operated animals. The magnitude of the reconstituted damage was anti-RNP Ab titer-dependent. Anti-RNP Ab-treated animals demonstrated a dose-dependent increase in lung histologic injury scores compared to control and sham animals. Anti-RNP mediated injury was shown to be complement dependent. These experiments reveal a novel mechanism whereby anti-RNP Abs contributes to the development of pulmonary pathology in patients with autoimmune diseases following exposure of remote organs to I/R injury. 相似文献

Under-representation of ethnic minority groups in bariatric surgery rates has been reported in the USA. Ethnic minorities form 7.9 % of the UK population, but comparable data on provision of bariatric surgery for these groups have not previously been reported in the UK. We calculated an estimate of rates of bariatric surgery amongst ethnic groups in the UK and Ireland using data from the National Bariatric Surgery Registry and census data from the UK and Ireland. The number of procedures recorded per 1,000 morbidly obese patients was 5.2 for Caucasian patients, 5.2 for Asian patients and 5.2 for Black patients. The identical rates across different ethnic groups suggest that bariatric services are provided equitably in the UK, with ethnic minority groups achieving equal access. 相似文献

A 24-year-old female, otherwise healthy, presented to the Emergency Department (ED) with difficulty walking and bilateral leg pain. The patient was a recreational nitrous oxide (NO2) user, also known as “whippets” or simply nitrous. Neurologic examination demonstrated an unsteady gait and positive Romberg sign along with normal deep tendon reflexes and normal muscle strength in upper and lower extremities. Laboratory results demonstrated macrocytic erythropoiesis, reduced B12, elevated homocysteine, and elevated methylmalonic acid. Outpatient MRI later demonstrated degeneration of the posterior spinal column. The patient was empirically treated in the ED with intramuscular B12 and admitted to the evaluation unit for pain control and Physical Therapy (PT) evaluation.Emergency Medicine (EM) physicians should be aware of this condition because NO2 is used both recreationally and in medicine. With the popularity of recreational nitrous oxide, many emergency patients have experience with this drug. As in our case report, the toxic effects can be profound and mimic other emergent conditions like stroke. Emergency physicians should have a higher index of suspicion for the toxic effects of this common drug. Elderly, vegetarians and patients with Irritable Bowel Disease are at higher risk and may even experience toxicity from nitrous oxide used therapeutically during routine anesthesia. 相似文献

Spirituality is about what is of utmost value; it is a values lens that asks “what really matters most to me, my family, our community, our country, and our world.” This personal reflection comes from a New Zealand academic who works in the spirituality and health care research field. Although largely biographical, this reflection offers some insight into the New Zealand context and this emergent field. 相似文献
