Objective To discuss the inflexion question in the course of measuring surface tension coefficient.Methods Metal frames with different lengths,radials and metal cylinders with different inside & outside radials were used to measure the inflexion.Results The inflexion appeared in the course of measuring surface tension coefficient by using force sensor and the inflexion changed with the different radials and lengths of the metal frames.Conclusion The thickness and bending of the fluid membrane results in the change of inflexion,and the inflexion can be avoided with the length and radial chosen properly.

Objective To compare the difference of clinical characteristics between patients with pituitary corticotroph macroadenoma and microadenoma. Methods From 1985 to 1998, 76 inpatients with Cushing′s disease, 12 cases of macroadenoma and 64 cases of microadenoma were reviewed. The clinical manifestations, the course before diagnosis, blood routine, biochemical and endocrinic examinations were retrospectively analyzed. Results Defect of vision field and galactorrhea were more frequent and the duration of disease before diagnosis were shorter in macroadenomas than those in microadenomas. Lymphopenia, hypokalaemia, lower creatine kinase level and hyperphosphoroemia were also more pronounced in macroadenomas. In macroadenomas, the plasma ACTH and cortisol (F) concentrations at 0:00 were obviously higher than those in microadenomas, but plasma ACTH and F at 8:00 and 24h urinary free cortisol were similar in these two groups. The relative nyctohemeral variation of ACTH was less in macroadenomas than that in microadenomas, the relative nyctohemeral variation of F was similar in these two groups. One month after operation, clinicl manifestations of macroadenomas significantly improved, but the number of these patients with significant blood ACTH decrease was significantly less than that in microadenomas. Conclusion Due to higher amount and automatism of ACTH secretion, increased blood F level induces variation of clinical characteristics and laboratorial findings in patients with macroadenoma compared to the patients with microadenoma.

Background:Disruption of intestinal epithelial tight junction and the followed barrier function play important roles in the pathogenesis of intestinal disorders. Curcumin could provide protection for the impaired barrier function. Aims:To investigate the protective effect of curcumin on ethanol-induced intestinal mucosal barrier disruption. Methods:Caco-2 cells were cultured to establish intestinal epithelial cell barrier model in vitro,and then were divided into control group, ethanol group and different concentrations of curcumin groups(5,20,80 μmol/ L curcumin). Trans-epithelial electrical resistance(TEER)and flux of sodium fluorescein for Caco-2 cell monolayers were measured to examine intestinal epithelial barrier function. Expression and localization of Occludin protein were measured by Western blotting and immunofluorescence,respectively. Cell structure was observed by transmission electron microscopy( TEM). Results:Compared with control group,TEER was significantly decreased and flux of sodium fluorescein was significantly increased (P < 0. 05),expression of Occludin protein was significantly decreased(P < 0. 05)in ethanol group. Immunofluorescence showed that Occludin protein expression was discontinuous and fluorescence intensity was low. TEM showed that brusher border was disorganized,and cell-cell junction was vague. When pretreated with curcumin,the above-mentioned indices were significantly improved,especially in 20 μmol/ L curcumin group( P < 0. 05). Conclusions:Curcumin protects ethanol-induced intestinal epithelial cell barrier disruption.

12 months in 31.3% (15/48). The graft lesions were found in 72.9% (35/48) of the patients, the worsened native lesions in 8.3% (4/48) and incomplete revascularization in 12.5% (6/48). Total occlusion was found in 33.3% (45/135) of the grafts and stenosis in 5.9% (8/135). LIMA total occlusion was 46.4% (13/28), stenosis was 8.6% (3/35) and competitive flow was 8.6% (3/35). Stenosis was found in 5.2% (5/97) of the SVG and total occlusion in 35.1% (34/97). Two of the five radial arteries were stenotic. Except for the chronic total occlusions, PCI treated the above problems with a high success rate. Conclusion Reoccurrence of angina is not uncommon after CABG. The causes are mainly due to the graft problem, and secondly due to worsened native lesion and incomplete revascularization. PCI can be used to treat the above problems except for the chronic total occlusions of the native vessels and graft.

The aim of this study was to investigate factors contributing to left ventricular dysfunction (LVD) in patients who had survived acute myocardial infarction(AMI). Retrospective regression analysis was performed for all the hospitalized patients with AMI who underwent coronary angiography from 1988 to 1998. 155 patients met the entry criteria. Seven patients(4 5%) died of cardiac events after discharge during the ten years′ follow up. In the multivariate logistic regression analysis and stepwise selection, the following factors appeared to be the significantly independent predictors of the LVD after AMI : age, hypertension, hyperlipidemia, LVEF during the first admission, size of infarction, the number of vessel disease, thrombolytic therapy, PTCA. In the COX regression and stepwise selection, the following factors appeared to be significantly independent predictors of the LVD after AMI : hyperlipidemia, LVED during the first admission, size of infarction, the number of vessel disease, thrombolytic therapy , PTCA. The probability of LVD increased with time. Patients with advanced age, hypertension, hyperlipidemia, large infarction, multivessel disease, reduced LVEF after AMI, no thrombolysis and PTCA are prone to develop LVD.

Objective To explore the reasons why patients with Keshan disesse complicated with hypertension and their interaction in Fuyu County, Heilongjiang Province. Methods Fifty-three patients with Keshan disease were investigated in January, April and July in 2007. Blood pressure was measured and the risk factors of hypertension were investigated. According to the diagnostic criteria of hypertension, patients were divided into hypertension group and non-hypertension group, and then the risk factors of hypertension, as well as the course of Keshan disease, were compared between the two groups. The risk factors include age, gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity. Results The age of hypertension group[(57.83±8.89)years] was significantly higher than that of non-hypertension group [(51.53 ± 9.43)years, t = 2.3630, P < 0.05) ;while the course of Keshan disease in non-hypertension group [(31.63 ± 8.66)years] was notably longer than that in hypertension group [(25.08±11.41)years, t = 2.0224, P < 0.05] ;No statistically significant difference in gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity was observed between the two groups(χ2 = 0.0072,0.1779,0.0029,0.1555,0.119,0.7679, all P > 0.05). Conclusions Age might be an important factor in patients with Keshan disease accompanied by hypertension, and the role of other risk factors of hypertension should not be overlooked;whether Keshan disease and hypertension can affect each other needs further investigation.

Objective To assess the value of SureTouch tactile breast imaging (SureTouch) in early breast disease detection.Methods From April 2009 to March 2011,16 010 adults received health checkup in our center,5000 of whom took breast screening and were randonly selected to accept SureTouch.The results of the SureTouch were reviewed.Results In SureTouch,799 participants were normal,resulting in an abnormal rate of 84.02％.Four thousands and nineteen adults were found with breast hyperplasias (80.38％) and 150 with breast nodulars (3.00％),and another 32 women were suspected with malignant condition (0.64％).Breast hyperplasia was the most commonly seen disease in all age groups,although breast nodular and malignant changes were mainly found in 35-50 age group.The incidence of malignant disease showed a trend of affecting younger females.Pathological follow-up results of two controversial cases supported the diagnosis of SureTouch.Conclusions SureTouch shows high sensitivity in this study.The application of SureTouch in breast screening may play an important role in the early detection,diagnosis and treatment of breast diseases.
