METHODS: In the present prospective study, 335 patients underwent conventional white light (CWL) en-doscopy and non-magnifi ed/magnifi ed NBI endoscopy, followed by an endoscopic biopsy, for 445 superfi cial lesions in the oropharynx and hypopharynx. The macroscopic appearance of superfi cial lesions was categorized as either elevated (< 5 mm in height), flat, or depressed (not ulcerous). Superficial carcinoma (SC) was defi ned as a superfi cial lesion showing high-grade dysplasia or squamous cell carcinoma on histology. The color, delineation, and macroscopic appearances of the lesions were evaluated by CWL endoscopy. The ratio of the brownish area/intervascular brownish epithelium (IBE), as well as microvascular proliferation, dilation, and irregularities, was determined by non-magnifi ed/ magnifi ed NBI endoscopy. An experienced pathologist who was unaware of the endoscopic fi ndings made the histological diagnoses. By comparing endoscopic fi ndings with histology, we determined the endoscopic features of SC and evaluated the diagnostic utility of NBI. RESULTS: The 445 lesions were divided histologically into two groups: a non-SC group, including non-neoplasia and low-grade dysplasia cases, and an SC group. Of the 445 lesions examined, 333 were classified as non-SC and 112 were classif ied as SC. There were no significant differences in age, gender, or the location of the lesions between the patients in the two groups. The mean diameter of the SC lesions was signif icantly greater than that of non-SC lesions (11.0 ± 7.6 mm vs 4.6 ± 3.6 mm, respectively, P < 0.001). Comparisons of CWL endoscopy fi ndings for SC and non-SC lesions by univariate analysis revealed that the incidence of redness (72% vs 41%, respectively, P < 0.001) and a flat or depressed type of lesion (58% vs 44%, respectively, P = 0.013) was significantly higher in the SC group. Using non-magnifi ed NBI endoscopy, the incidence of a brownish area was signifi cantly higher for SC lesions (79% vs 57%, respectively, P < 0.001). On magnifi ed NBI endoscopy, the incidence of IBE (68% vs 33%, P < 0.001) and microvascular proliferation (82% vs 51%, P < 0.001), dilation (90% vs 76%, P =0.002), and irregularity (82% vs 31%, P < 0.001) was also signifi cantly higher for the SC compared with the non-SC lesions. Multivariate analysis revealed that the incidence of redness (P = 0.022) on CWL endoscopy and IBE (P < 0.001) and microvascular irregularities (P < 0.001) on magnif ied NBI endoscopy was signif icantly higher in SC than non-SC lesions. Redness alone exhibited signifi cantly higher sensitivity and signifi cantly lower specifi city for the diagnosis of SC compared with redness plus IBE and microvascular irregularities (72% vs 52%, P = 0.002; and 59% vs 92%, P < 0.001, respectively). The accuracy of redness plus IBE and irregularities for the diagnosis of SC was signifi cantly greater than using redness alone (82% vs 62%, respectively, P < 0.001). CONCLUSION: Redness, IBE, and microvascular irregularities appear to be closely related to SC lesions. Magnifi ed NBI endoscopy may increase the diagnostic accuracy of CWL endoscopy for SC.展开更多

Materials and Methods: Patients aged at least 18 years and older with clinical diagnosis of plaque psoriasis, were enrolled in this open label, non-comparative, multicenter trial. All eligible subjects received four 700 mg Tinefcon<sup>?</sup> tablets/day for 12 weeks. The primary outcome measure was percent change in Psoriasis Area Severity Index (PASI) score from baseline to week 12. The secondary outcome measures were Physician Global Assessment (PGA), Nail Psoriasis Severity Index (NAPSI), Psoriatic Arthritis Evaluation and Gene Expression Profiling and Immunohistochemistry. Results: After completion of Tinefcon<sup>?</sup> treatment at 12 weeks, more than half of subjects (52%) achieved PASI 50 response;PASI 75 response was attained in 68 (23%) subjects and PASI 90 response in 22 (7%) subjects. Five subjects with severe psoriasis achieved PASI 90 without receiving any concomitant medication. Reduction in severity as assessed by PGA was observed in more than half of patients with moderate disease. Histopathological evaluation revealed that epidermal thickness was considerably reduced in 66% of subjects. The expression of inflammatory marker S100A9 protein was(meaningfully reduced in 60% patients with non-significant reduction of Keratin 10 protein expression. Gene expression analysis showed increase down regulation of SERPINB4;PI3 and KRT16 genes after a 12-week treatment period in subjects with higher PASI scores. Conclusion: Oral Tinefcon<sup>?</sup> tablets showed good efficacy and had a favorable safety profile in plaque psoriasis patients.展开更多

METHODS:Twenty-two patients (15 men and 7 women; median age 68 years,range 56-81 years) underwent a liver tissue biopsy in order to make a diagnosis of HCC. Paraffin-embedded liver biopsy tissue samples from 22 patients were stained with anti-CD147 antibody,murine monoclonal antibody 12C3 (MAb12C3) for immunohistochemical analysis. An immunohistochemical analysis of CD147 was performed and the degree of staining compared between tumor and non-tumor tissue. In addition,the degree of staining within tumor tissue was compared according to a number of clinicopathological variables. RESULTS:The degree of staining of CD147 was significantly higher in tumor tissues than non-tumor tissues,even in tumors less than 15 mm in diameter.The expression of this protein was significantly elevated in HCC tissue specimens from patients with a low value of serum AST and γ-GTP.展开更多

Moreover, significant sex differences were found in cardiac structure, function, pathophysiology, presentation, treatment, and outcome of IHD. The presence of unique risk factors such as exposure to menarche and pregnancy, more anemia, hypertension, and autoimmune disorders in women have recently received attention. Ischemic symptoms are more indefinite and vague in women compared to men as well as a delay in diagnosis, treatment, and worse outcomes compared to men. Women usually receive less evidence-based treatment and intervention, with less concern on preventive health care. Clinical trials primarily recruit male patients and women are underrepresented. Without any correct diagnosis, treatment, and prevention, these problems are accumulated and continue up to older age. Accordingly, with the belief of longer life in women and the increased prevalence of IHD with aging, it will become an important public health problem and concern in the future. This narrative review aimed to provide an overview of some of the differences between the two genders in terms of IHD with paying more attention to practical points.展开更多

Carotid intima-media thickness(IMT) is a strong predictor of myocardial infarction and stroke. Methods and Results-We compared the effects of pioglitazone-based therapy(45 mg/d) and glimepiride-based treatment(2.7± 1.6 mg/d) for 12 and 24 weeks on metabolic control(HbA1c), insulin resistance(homeostasis model assessment), and carotid IMT(B-mode ultrasonography) in a randomized controlled study in 173 orally treated patients with type 2 diabetes(66 women, 107 men; mean± SD age, 62.6± 7.9 years; body mass index, 31.8± 4.6 kg/m2; HbA1c, 7.5± 0.9% ). Treatment was generally well tolerated in both groups. Despite similar improvements in metabolic control(HbA 1c) after 24 weeks(- 0.8± 0.9% [pioglitazone] versus - 0.6± 0.8% [glimepiride]; P=NS), carotid IMT was reduced only in the pioglitazone group after 12 weeks(- 0.033± 0.052 versus- 0.002± 0.047mm[glimepiride]; P< 0.01 between groups) and 24 weeks(- 0.054± 0.059 versus - 0.011± 0.058 mm[glimepiride]; P< 0.005 between groups). Insulin resistance was also improved only in the pioglitazone group(homeostasis model assessment,- 2.2± 3.4 versus- 0.3± 3.3; P< 0.0001 between groups). Reduction of IMT correlated with improvement in insulin resistance(r=0.29, P< 0.0005) and was independent of improvement in glycemic control(r=0.03, P=0.68). Conclusions-We found a substantial regression of carotid IMT, independent of improved glycemic control, after 12 and 24 weeks of pioglitazone treatment. This finding may have important prognostic implications for patients with type 2 diabetes mellitus.展开更多

文摘Patients with type 2 diabetes mellitus are at high risk of cardiovascular disease. Carotid intima-media thickness(IMT) is a strong predictor of myocardial infarction and stroke. Methods and Results-We compared the effects of pioglitazone-based therapy(45 mg/d) and glimepiride-based treatment(2.7± 1.6 mg/d) for 12 and 24 weeks on metabolic control(HbA1c), insulin resistance(homeostasis model assessment), and carotid IMT(B-mode ultrasonography) in a randomized controlled study in 173 orally treated patients with type 2 diabetes(66 women, 107 men; mean± SD age, 62.6± 7.9 years; body mass index, 31.8± 4.6 kg/m2; HbA1c, 7.5± 0.9% ). Treatment was generally well tolerated in both groups. Despite similar improvements in metabolic control(HbA 1c) after 24 weeks(- 0.8± 0.9% [pioglitazone] versus - 0.6± 0.8% [glimepiride]; P=NS), carotid IMT was reduced only in the pioglitazone group after 12 weeks(- 0.033± 0.052 versus- 0.002± 0.047mm[glimepiride]; P< 0.01 between groups) and 24 weeks(- 0.054± 0.059 versus - 0.011± 0.058 mm[glimepiride]; P< 0.005 between groups). Insulin resistance was also improved only in the pioglitazone group(homeostasis model assessment,- 2.2± 3.4 versus- 0.3± 3.3; P< 0.0001 between groups). Reduction of IMT correlated with improvement in insulin resistance(r=0.29, P< 0.0005) and was independent of improvement in glycemic control(r=0.03, P=0.68). Conclusions-We found a substantial regression of carotid IMT, independent of improved glycemic control, after 12 and 24 weeks of pioglitazone treatment. This finding may have important prognostic implications for patients with type 2 diabetes mellitus.
