目的探讨结膜印迹细胞的流式细胞术凋亡检测在干眼发病机制研究与结缔组织病患者干眼诊断中的应用价值。方法对结缔组织病患者60例(120眼)进行眼科病史询问、泪液分泌实验Ⅰ(S-I-T)、泪膜破裂时间(BUT)及荧光素染色计分(FL)检查,根据检查结果和有无Sjogren综合征分为非干燥综合征无干眼(NSS1)组、非干燥综合征干眼(NSS2)组、干燥综合征无干眼(SS1)组和干燥综合征干眼(SS2)组。并对其行结膜印迹细胞流式细胞术凋亡检测。结果结膜上皮细胞凋亡百分比除NSS1组与SS1组间差异无统计学意义(P=0.998)外,其余各组差异均有统计学意义(P〈0.001)。且细胞凋亡百分比与FL成正相关(r=0.926,P〈0.001),与S-I-T、BUT结果成负相关(r=–0.712,r=–0.818,P〈0.001)。有无干眼和有无干燥均影响结膜上皮细胞凋亡量,且干眼与干燥有交互作用。结论细胞凋亡可能是造成干眼眼表损害的重要因素,凋亡检测有助于结缔组织病患者干眼的诊断。干眼和干燥均可使结膜上皮细胞凋亡增加。印迹细胞流式细胞凋亡检测是一项微创、有效的眼表凋亡检测方法。 相似文献

Lung involvement in connective tissue diseases is associated with substantial morbidity and mortality, most commonly in the form of interstitial lung disease, and can occur in any of these disorders. Patterns of interstitial lung disease in patients with connective tissue disease are similar to those seen in idiopathic interstitial pneumonias, such as idiopathic pulmonary fibrosis. It may be difficult to distinguish between the 2 ailments, particularly when interstitial lung disease presents before extrapulmonary manifestations of the underlying connective tissue disease. There are important clinical implications in achieving this distinction. Given the complexities inherent in the management of these patients, a multidisciplinary evaluation is needed to optimize the diagnostic process and management strategies. The aim of this article was to summarize an approach to diagnosis and management based on the opinion of experts on this topic. 相似文献

Non-insulin-dependent diabetes mellitus (NIDDM) increases substantially the risk for all manifestations of atherosclerotic vascular disease, coronary heart disease (CHD), cerebrovascular disease and peripheral vascular disease. Only a small proportion of this excess risk can be explained by the effects of conventional cardiovascular risk factors, which implies that the diabetic state or factors related to it have to play a significant role in the pathogenesis of macrovascular disease in NIDDM. Six recent prospective population-based studies including a large number of NIDDM patients have indicated that poor glycaemic control evaluated by fasting hyperglycaemia or glycosylated haemoglobin levels increases the risk for CHD, stroke and amputation independently of other risk factors. A dose-response relationship between markers of glycaemic control and the incidence of cardiovascular mortality and morbidity has been demonstrated in all these studies. However, there is so far no direct proof that strict glycaemic control would delay or prevent atherosclerotic complications. 相似文献

PurposeGlycemic control in patients with chronic kidney disease (CKD) is particularly hard to achieve because of a slower insulin degradation by the kidney. It might modify the long-acting insulin analogue pharmacokinetics, increasing its time–action and the risk of hypoglycemia. However, because this insulin has no peak action, it might be a more tolerable approach to patients with CKD. This hypothesis remains to be tested, because no study has thus far examined the efficacy and safety profile of long-acting basal analogues in patients with significant loss of renal function. The purpose of this study was to compare the glycemic response to treatment with glargine U100 or neutral protamine Hagedorn (NPH) insulin in patients with type 2 diabetes mellitus (T2DM) and CKD stages 3 and 4.MethodsThirty-four patients were randomly assigned to glargine U100 or NPH insulin after a 2-way crossover open-label design. The primary end point was the difference in glycosylated hemoglobin (HbA1c) and in the number of hypoglycemic events between weeks 1 and 24, whereas secondary end points included changes in glycemic patterns, weight and body mass index, and total daily dose of insulin. HbA1c was determined by ion-exchange HPLC, and hypoglycemia was defined as glucose concentration of 54 mg/dL (3.0 mmol/L) detected by self-monitoring of plasma glucose or continuous glucose monitoring.FindingsAfter 24 weeks, mean HbA1c decreased on glargine U100 treatment (−0.91%; P < 0.001), but this benefit was not observed for NPH (0.23%; P = 0.93). Moreover, incidence of nocturnal hypoglycemia was 3 times lower with glargine than with NPH insulin (P = 0.047).ImplicationsOur results found that insulin glargine U100 could be effective, once it improved glycemic control, reducing HbA1c with fewer nocturnal hypoglycemia episodes compared with NPH insulin in this population. These clinical benefits justify the use of basal insulin analogues, despite their high cost to treat patients with T2DM and CKD stages 3 and 4. Clinical Trials identifier: NCT02451917. 相似文献

BACKGROUNDSevere lower gastrointestinal bleeding (SLGIB) is a rare complication of Crohn''s disease (CD). The treatment of these patients is a clinical challenge. Monoclonal anti-TNFα antibody (IFX) can induce relatively fast mucosal healing. It has been reported for the treatment of SLGIB, but there are few reports on accelerated IFX induction in CD patients with SLGIB.CASE SUMMARYA 16-year-old boy with a history of recurrent oral ulcers for nearly 1 year presented to the Gastroenterology Department of our hospital complaining of recurrent periumbilical pain for more than 1 mo and having bloody stool 4 times within 2 wk. Colonoscopy showed multiple areas of inflammation of the colon and a sigmoid colon ulcer with active bleeding. Hemostasis was immediately performed under endoscopy. The physical examination of the patient showed scattered small ulcers in the lower lip of the mouth and small cracks in the perianal area. Combined with his medical history, physical examination, laboratory examinations with high C-reactive protein (CRP), platelet count (PLT), erythrocyte sedimentation rate (ESR) and fecal calprotectin levels, imaging examinations and pathology, a diagnosis of CD was taken into consideration. According to the pediatric CD activity index 47.5, methylprednisolone (40 mg QD) was given intravenously. The abdominal pain disappeared, and CRP, PLT, and ESR levels decreased significantly after the treatment. Unfortunately, he had a large amount of bloody stool again after 1 wk of methylprednisolone treatment, and his hemoglobin level decreased quickly. Although infliximab (IFX) (5 mg/kg) was given as a combination therapy regimen, he still had bloody stool with his hemoglobin level decreasing from 112 g/L to 80 g/L in a short time, so-called SLGIB. With informed consent, accelerated IFX (5 mg/kg) induction was given 7 days after initial presentation. The bleeding then stopped. Eight weeks after the treatment, repeat colonoscopy showed mucosal healing; thus far, no recurrent bleeding has occurred, and the patient is symptom-free.CONCLUSIONThis case highlights the importance of accelerated IFX induction in SLGIB secondary to CD, especially after steroid hormone treatment. 相似文献

SHIMIZU, A., et al. : Double Ventricular Response by a Single Ventricular Extrastimulus to the Inner Loop of Reentry in a Patient Without Apparent Heart Disease. In a patient without apparent heart disease, a ventricular extrastimulus delivered from the left ventricular apex where the electrogram was recorded 30 ms after the onset of the QRS complex during VT advanced the second QRS complex, but not the first QRS complex. The morphology of the second QRS complex was the same as that of VT. The postpacing interval was the same as the cycle length of the VT. These findings indicated that the site of stimulation was at the inner loop of the reentry circuit of the VT. A ventricular extrastimulus with a shorter coupling interval advanced the first and second QRS complexes, indicating that the ventricle was activated by antidromic and orthodromic activation from the extrastimulus. Radiofrequency ablation at that site of stimulation terminated the VT and no further VT could be induced. 相似文献
