To analyze and summarize the clinicopathological features of renal inflammatory lesions which were easily misdiagnosed as renal tumors.Methods The cases from March 2006 to August 2015 in the Department of Pathology at Xijing Hospital were analyzed,retrospectively.Due to the diagnosis made by clinicians that these were renal (including renal pelvic) tumors,all cases had undergone radical nephrectomy or tumor enucleation.Among them,several inflammatory lesions were confirmed,and were combined with the patients' clinicopathological data and literature review to investigate the diagnosis and differential diagnosis.Results Of the 1 195 cases,only 6 cases (less than 1％) were renal inflammatory lesions,named as xanthogranulomatous pyelonephritis (2 cases),renal malakoplakia (1 case),renal tuberculosis (1 case),IgG4-related tubulointerstitial nephritis (1 case),and renal Wegener's granulomatosis (1 case).These diseases occurred in two males and four females (aged 14 to 55 years).All patients underwent radical nephrectomy due to the detected unilateral solitary renal mass in the imaging examination.Conclusion Renal inflammatory lesions are very rare,which show masses that are easily misdiagnosed as neoplastic lesions.Some of them have similar histological features.As the differences of treatment,a sufficient understanding of the clinicopathological features of these diseases is important to make a correct diagnosis.

Objective To explore the effect of minimally invasive clinical pathway in patients after car-diac interventional therapy. Methods One hundred and twenty patients who received cardiac interventional therapy from June 2005 to October 2006 were divided into the control group and the observation group.The control group received routine nursing while the observation group adopted minimally invasive clinical pathway of nursing.The nursing effect in the two groups was compared. Results The mean hospitalized duration, sat-isfaction degree and health knowledge level in the observation group were superior to those of the control group (P ＜ 0.05). Conclusions The adoption of minimally invasive clinical pathway in patients after cardiac inter-ventional therapy could increase working efficiency nd ensure the nusing quality.

Objective To study interleukin-1 receptor(IL-1R) and connexin(Cx36) gene expression following Mg 2+-free-induced seizures in cultured developing neuron. Methods Rat embryo cortical neurons cultured for 6 and 17 days were exposed to Mg 2+-free media to induce seizure. At different time after Mg 2+-free treatment, real-time RT-PCR was used to detect IL-1R and Cx36 mRNA expression. Results 1. IL-1R mRNA expression transiently decreased after Mg 2+-free treatment in neurons cultured for 6 and 17 days in vitro. Then the levels of IL-1R mRNA expression recovered in neurons cultured for 6 days, but IL-1R mRNA expression were increased in neurons cultured for 17 days compared with control group and the peak was at 24 hours. 2. In neurons cultured for 6 days in vitro, Cx36 mRNA expression increased after Mg 2+-free treatment compared with control group, the peak was at 24 hours. But in neurons cultured for 17 days in vitro, Cx36 mRNA expression decreased at 6 hours after Mg 2+-free treatment compared with control group, the peak was at 24 hours. Conclusions IL-1R mRNA and Cx36 mRNA expression following Mg 2+-free-induced seizures are different between the neurons cultured for 6 and 17 days in vitro. This is possibly related to the different neuron injury between 6 and 17 days in vitro following seizures.

Objective:To explore the expression of N-cadherin and its correlations with the clinicopathological features of human ovarian carcinoma.Methods:The expression of N-cadherin in 281 cases of ovarian carcinoma tissues were determined by immunohistochemical method.The correlations of N-cadherin expression with the clinicopathological features of human ovarian carcinoma were analyzed.Results:There was higher expression of N-cadherin in the metastatic lesions than its paired primary lesions (P =0.018).The expression level of N-cadherin in ovarian carcinoma was correlated with the FIGO stage (P =0.034),histological type (P ＜0.001) and tumor grade (P =0.004).Conclusions:High expression of N-cadherin might positively correlate with the invasion and migration ability of ovarian carcinoma cells,which was more common in the the advanced (FIGO Ⅱ-Ⅳ) ovarian carcinoma,high-grade serous carcinoma,and high grade ovarian carcinoma.N-cadherin might be useful in estimating the biological behavior of human ovarian carcinoma.

The aim of this paper was to investigate the effect of terpene penetration enhancers on membrane fluidity and membrane potential using HaCaT keratinocytes, and study the potential mechanisms of these terpene compounds using as natural transdermal penetration enhancer. Six terpene compounds, namely menthol, limonene, 1,8-cineole, menthone, terpinen-4-ol and pulegone, were chosen in this study on account of their good penetration-enhancement activities. The cytotoxicity of these terpene compounds was measured using an MTT assay. The fluorescence recovery after photobleaching (FRAP) technique was employed to measure the change of membrane fluidity of HaCaT cells. The flow cytometer was used to study the alteration of membrane fluidity of HaCaT cells, and investigate the effect of terpene compounds on intracellular Ca2+. It was found that 6 terpene compounds possessed low cytotoxicity in comparison to the well-established and standard penetration enhancer azone. Those terpene compounds could significantly enhance HaCaT cells membrane fluidity and decrease HaCaT cells membrane potentials. Meanwhile, after treated with various terpene compounds, the Ca2(+)-ATPase activity and intracellular Ca2+ of HaCaT cells was decreased significantly. Terpene penetration enhancers perhaps changed the membrane fluidity and potentials of HaCaT cells by altering the Ca2+ balance of the cell inside and outside, resulting in the low skin permeability to increase the drug transdermal absorption.

Objective: To analyze the relationship between thrombin activatable fibrinolysis inhibitor ( TAFI ) and coronary heart disease ( CHD ), and to provide evidence for the prevention of CHD. Methods: The patients with CHD in Fushun Central Hospital in Liaoning Province were selected as the case group, the patients without CHD in the same hospital and period were selected as the control group. The demographic information and clinical examination results ( serum TAFI, lipid, glucose, etc. ) were collected to analyze the association between TAFI and CHD by logistic regression models.The multivariate logistic regression analysis was used to explore the relationship between TAFI and CHD. Results: There were 222 cases, including 100 cases of stable angina, 44 cases of unstable angina and 78 cases of acute myocardial infarction, and 222 controls. The median ages of cases and controls were 62 and 57 years old. The results of multivariate logistic regression analysis showed that serum TAFI>22.88 μg/mL ( P75 of controls ) was associated with the risk of CHD ( OR=1.619, 95%CI: 1.011-2.593 ), unstable angina ( OR=2.917, 95%CI: 1.433-5.939 ) and acute myocardial infarction ( OR=2.626, 95%CI: 1.007-6.847 ). Conclusion The high level of TAFI is related to CHD, unstable angina and acute myocardial infarction.
