目的利用小鼠黏膜炎症因子模型,研究不同浓度苯扎氯铵(BZK)对生殖道黏膜的刺激毒性,以探究BZK作为黏膜用药物的安全性和应用前景。方法连续三天用浓度为0.02%、0.2%和2%的BZK凝胶处理小鼠阴道黏膜,每天收集小鼠阴道灌洗液,用多指标流式蛋白定量技术(Cytometric Bead Array,CBA)检测其中的6种炎症因子[白介素(Interleukin,IL)-2、IL-4、IL-6、IL-17A和肿瘤坏死因子(Tumor necrosis factor,TNF)-α、γ干扰素(Interferonγ,IFN)-γ]的表达情况;利用苏木紫-伊红(Hematoxylin-Eosin,HE)染色法对小鼠阴道黏膜的病理学损伤情况进行观察。结果 2%的BZK凝胶诱导了较为明显的小鼠阴道黏膜上皮损伤,0.02%和0.2%的BZK与安慰剂组相比无明显病理改变;但是0.2%的BZK显著上调了IL-6和TNF-α在阴道灌洗液中的表达,而0.02%和2%的BZK诱导的各炎症因子与安慰剂组相比差异无统计学意义。结论 2%和0.2%的BZK具有一定的黏膜毒性;0.02%的BZK展现了较好的安全性,该浓度下BZK的病原体感染抑制能力需要进一步研究确认。 相似文献

Most adenomas and carcinomas of the small intestine and extrahepatic bile ducts arise in the region of the papilla of Vater. In familial adenomatous polyposis (FAP) it is the main location for carcinomas after proctocolectomy. In many cases symptoms due to stenosis lead to diagnosis at an early tumor stage. In about 80%, curative intended resection is possible. Operability is the most relevant prognostic factor. Most ampullary carcinomas resp. carcinomas of the papilla of Vater develop from adenomatous or flat dysplastic precursor lesions. They can be sited in the ampulloduodenal part of the papilla of Vater, which is lined by intestinal mucosa. They also can develop in deeper parts of the ampulla, which are lined by pancreaticobiliary duct mucosa. Intestinal-type adenocarcinoma and pancreaticobiliary-type adenocarcinoma represent the main histological types of ampullary carcinoma. Furthermore, there exist unusual types and undifferentiated carcinomas. Many carcinomas of intestinal type express the immunohistochemical marker profile of intestinal mucosa (keratin 7?, keratin 20+, MUC2+). Carcinomas of pancreaticobiliary type usually show the immunohistochemical profile of pancreaticobiliary duct mucosa (keratin 7+, keratin 20?, MUC2?). Even poorly differentiated carcinomas, as well as unusual histological types, may conserve the marker profile of the mucosa they developed from. These findings underline the concept of histogenetically different carcinomas of the papilla of Vater which develop either from intestinal- or from pancreaticobiliary-type mucosa of the papilla of Vater. Molecular alterations in ampullary carcinomas are similar to those of colorectal as well as pancreatic carcinomas, although they appear at different frequencies. In future studies, molecular alterations in ampullary carcinomas should be correlated closely with the different histologic tumor types. Consequently, the histologic classification should reflect the histogenesis of ampullary tumors from the two different types of papillary mucosa. 相似文献

Summary Palmitic acid oxidation in rat diaphragm homogenate is depressed by biguanide concentrations that are still incapable of inhibiting
oxidative phosphorylation. Glucose oxidation is not directly effected by the same biguanide concentrations: however, the inhibitory
effect of palmitic acid on glucose oxidation is partly removed by biguanides. Inhibition of fatty acid oxidation, which accounts
for most of the metabolic effects caused by these drugs, can be regarded as the fundamental mechanism of action of biguanides.
There is some evidence suggesting that these drugs might interact with carnitine, thus preventing long-chain fatty acids from
being transported across the mitochondrial membrane to the site of oxidation.

BACKGROUND AND AIM: Both the clinical presentation and the degree of mucosal damage in coeliac disease vary greatly. In view of conflicting information as to whether the mode of presentation correlates with the degree of villous atrophy, we reviewed a large cohort of patients with coeliac disease. PATIENTS AND METHODS: We correlated mode of presentation (classical, diarrhoea predominant or atypical/silent) with histology of duodenal biopsies and examined their trends over time. RESULTS: The cohort consisted of 499 adults, mean age 44.1 years, 68% females. The majority had silent coeliac disease (56%) and total villous atrophy (65%). There was no correlation of mode of presentation with the degree of villous atrophy (p=0.25). Sixty-eight percent of females and 58% of males had a severe villous atrophy (p=0.052). There was a significant trend over time for a greater proportion of patients presenting as atypical/silent coeliac disease and having partial villous atrophy, though the majority still had total villous atrophy. CONCLUSIONS: Among our patients the degree of villous atrophy in duodenal biopsies did not correlate with the mode of presentation, indicating that factors other than the degree of villous atrophy must account for diarrhoea in coeliac disease. 相似文献

The aim of the study was to assess the quality of life (QOL) and the psychological status of parents of children with juvenile
chronic arthritis (JCA). The QOL, anxiety and depression of the parents of 28 children with JCA were evaluated and compared
to those of the parents of 28 healthy children. Mothers of JCA children and mothers of healthy children reported similar QOL.
The reported anxiety and depression levels were similar for mothers and fathers in both groups. The parents of children with
pauciarticular-type JCA reported lower QOL and higher levels of anxiety and depression than the parents of children with other
types, namely polyarticular and systemic JCA. These findings may be explained by the fact that the pauciarticular patients
had shorter disease duration and were less frequently seen in the outpatient clinic. The QOL of mothers of children with JCA
was found to be slightly impaired in the group of children with pauciarticular JCA. Future larger studies are needed to confirm
these results, as the number of subjects in the three groups was rather low.

Background
A 5-day in-patient study designed to assess the accuracy of the FreeStyle Navigator® Continuous Glucose Monitoring System revealed that the level of accuracy of the continuous sensor measurements was dependent on the rate of glucose change. When the absolute rate of change was less than 1 mg•dl−1•min−1 (75% of the time), the median absolute relative difference (ARD) was 8.5%, with 85% of all points falling within the A zone of the Clarke error grid. When the absolute rate of change was greater than 2 mg•dl−1•min−1 (8% of the time), the median ARD was 17.5%, with 59% of all points falling within the Clarke A zone.Method
Numerical simulations were performed to investigate effects of the rate of change of glucose on sensor measurement error. This approach enabled physiologically relevant distributions of glucose values to be reordered to explore the effect of different glucose rate-of-change distributions on apparent sensor accuracy.Results
The physiological lag between blood and interstitial fluid glucose levels is sufficient to account for the observed difference in sensor accuracy between periods of stable glucose and periods of rapidly changing glucose.Conclusions
The role of physiological lag on the apparent decrease in sensor accuracy at high glucose rates of change has implications for clinical study design, regulatory review of continuous glucose sensors, and development of performance standards for this new technology. This work demonstrates the difficulty in comparing accuracy measures between different clinical studies and highlights the need for studies to include both relevant glucose distributions and relevant glucose rate-of-change distributions. 相似文献20.
治疗高血压药物的经济学评价 总被引:3,自引:0,他引:3
重视高血压治疗中的经济学评价,对利用我国有限的卫生资源来遏制高血压对人民群众的危害有着重要的现实意义。药物经济学对于药物治疗的成本和治疗的结果给予同样的关注。因为治疗高血压的费用,不仅涉及药物价格,还包括患者的危险水平,降压疗效和对临床终点事件的影响,以及治疗的依从性和安全性。因此药物经济学更强调整体成本和价-效比。低危病人,若非药价低廉,治疗的价-效比不够理想。而在高危的患者,价-效比越小越经济而不是药费越便宜越好。 相似文献
