Objective To investigate the clinical,endoscopic and pathologic features in the differential diagnosis between Crohn' s disease (CD) and intestinal tuberculosis (ITB).Methods The complete clinical data of 107 patients with CD and 69 patients with ITB in our hospital from January 2011 to January 2012 were retrospectively analyzed.The diagnostic value of the clinical and endoscopic scoring system was evaluated.Results CD occurred mainly in male.The salient features of CD included long duration of disease high incidence of colectomy.Comparing with patients with ITB,patients with CD have more cases of diarrhea,hematochezia,abdominal mass,intestinal obstruction,intestinal hemorrhage,perianal lesions,and extraintestinal manifestations (all P ＜ 0.05).It's more frequent to have positive results of anti-Saccharomyces cerevisiae antibody (ASCA),perinuclear antineutrophil cytoplasmic antibody (pANCA) and fecal occult blood in CD patients,as well as low albumin,high C-reactive protein (CRP),elevated platelet count and hematocrit (P ＜ 0.05 or P ＜ 0.01).The salient features of ITB included low fever,night sweats,active parenteral tuberculosis,increased erythrocyte sedimentation rate (ESR),chest X-ray abnormalities,the positive PPD (purified protein derivatives tuberculin) and T-SPOT (P ＜ 0.05 or P ＜0.01).Based on the imaging,CD often involved the small intestine,such as the intestinal stricture and abdominal abscess (P ＜ 0.05),while mesenteric lymphadenopathy was more common in ITB (P ＜ 0.05).The endoscopic examination showed that some patterns of disease involvement such as fissure-shape ulcer [41.12％ (44/107) vs 5.80％ (4/69)],cobblestone sign [15.89％ (17/107) vs 4.35％ (3/69)],lesions over four segment [24.30％ (26/107) vs 7.25％ (5/69)],rectum involvement [17.76％ (19/107) vs 5.80％ (4/69)],ileocecal valve stenosis [21.50％ (23/107) vs 8.70％ (6/69)] and mucosal bridge [5.61％ (6/107) vs 0(0/69)] were more frequent in CD patients than those in ITB patients(P ＜ 0.01 or P ＜0.05).However circular ulcers[37.68％ (26/69) vs 9.35％ (10/107)],rat-bite-like ulcers[24.64％ (17/69) vs 12.15％ (13/107)],persistent open ileocecal valves [39.13％ (27/69) vs 19.63％ (21/107)],tuberous and polypoid lesions [36.23％ (25/69) vs 20.56％ (22/107),37.68％ (26/69) vs 22.43％ (24/107)] were more common in ITB (P ＜ 0.01 or P ＜ 0.05).In terms of pathological findings,certain characteristic features such as transmural inflammation [5.61％ (6/107) vs 0 (0/69)],fissure-liked ulcers [14.02％ (15/107) vs 4.35％ (3/69)],non-caseous granulomas [5.61％ (6/107) vs 0(0/69)],lymphoid hyperplasia [16.82％ (18/107) vs 5.80％ (4/69)] and crypt abscess [9.35％ (10/107) vs 1.45％ (1/69)] were more common in CD than those in ITB(P ＜ 0.05).According to the clinical and endoscopic scoring system,the positive diagnostic rate of CD was 50.47 ％ (54/107)and of ITB was 66.67 ％ (46/69) (P ＜ 0.05).Conclusions The differential diagnosis between CD and ITB should be considered carefully based on clinical,endoscopic,pathological characteristics.The clinical and endoscopic scoring system may contribute to distinguish CD and ITB.

Objective To investigate living quality of patients after orthotopic cardiac transplantation and to provide scientific evidence for specific strategy of therapy and improvement of living quality of patients with cardiac transplantation. Methods SF-36 and the social support questionnaire were used to analyze living quality of 79 patients who received orthotopic cardiac transplantation in the Department of Cardiovascular surgery of Affiliated Union Hospital of Fujian Medical University. The mode of SF-36 was from the investigative numerical value of residents in Sichuan province. Description, t-test and Spearman correlation analysis were used to study the related factors. Results Compared with a reference general population, the heart transplant recipients showed a significantly worse living quality score on all domains of the SF-36 scales (P＜0. 05), except the domain of somatic pain. Among the patients after cardiac transplantation, living quality was more significantly improved in ＞2-year survival group than that in ＜one-year survival group (P＜0. 05),except the domain of somatic pain. The relationships between the social support and living quality were analyzed,and it was found that as compared with a reference general population, the heart transplant recipients showed significantly lower scores on all domains of the social support questionnaire (P＜0. 01 ). The total social support scores were positively related to mental health related living quality (P＜0.05, r = 0.223 - 0.710), except the domain of somatic pain. Conclusion Compared with a general population, heart transplant recipients demonstrated a significantly worsened living quality. But evidence showed the living quality can be improved gradually with the prolongation of the survival time after heart transplantation. Social support was related to the living quality of heart transplantation patients. Improvement of availability on social support will probably improve living quality.

Objective To identify the effects of parenteral nutrition (PN) on the gene expressions of rat intestinal inflammatory cytokincs and receptors and to explore the role of these changes in PN-related intestinal impairment. Methods Totally 12 male Sprague-Dawley rats were equally divided into the control group and the PN group. A silastic catheter was inserted into the right jugular vein of each rat. No food or water was administered to the PN group except for a continuous 24-hour PN infusion through the silastic catheter in the jugular vein. The control group, while being regularly fed, was administered with an infusion of normal saline through the silastic catheter in thc jugular vein. After 7 days, intestinal tissues were taken for electron microscopy and real-time PCR array to analyze thc microstructure change in rat intestine and thc gene expressions of inflammatory cytokines and their receptors. Results Electron microscopy revealed atrophy of microvillus, engorgement of mitochondria, cell-cell junction breakage, and several apoptotic bodies in the PN group and normal intestinal microstructure in the control group. Compared with the control group, the PN group showed an up-regulation in the gene expressions of interferon γ, interleukin-1 receptor type I , interlcukin-8 receptor type b and a down-regulation in the gene expressions of CC chemokine ligand 17 (CCL17) , CCL19, CCL21, CCL22, CCL9, CXC chemokine receptor 3, CC chemokine receptor 3 ( CCP3 ), CCR7, CCR5, C-reactive protein, and interleukin-10. Conclusions PN influences the gene expressions of rat intestinal inflammatory cytokincs and receptors. The expression of cytokine interferon γ increases and that of interleukin-10 declines, and the expressions of CCL19, CCL21, CXC chemokine receptor 3, CCR3,CCR7, and CCR5 decline. The alterations of these genes may be associated with the impairment of intestinal immune and mechanical functions.

Objective To investigate the effect of promoter hypermethylation of O 6 methylguanine DNA methyltransferase (MGMT) gene on colorectal tumorigenesis and progression. Methods The promoter hypermethylation of O 6 methylguanine DNA methyltransferase gene was assayed in 27 sporadic colorectal adenomas, 62 sporadic colorectal carcinomas and 20 normal colorectal mucosa tissues by methylation specific PCR. At the same time, the expression of MGMT protein was studied in the same samples using immunohistochemistry. Results None of the normal colorectal mucosa tissues showed methylated bands. Promoter hypermethylation was detected in 40.7%(11/27) of adenomas and 43.5% (27/62) of carcinomas, respectively. MGMT proteins were expressed in nucleus and cytoplasm of normal colorectal mucosa tissues. Loss of MGMT expression was found in 22.2% (6/27) of adenomas and 45.2% (28/62) of carcinomas, respectively. There were significant difference among them ( P =0.041). Methylation was detected in 5 of the 6 adenomas( P =0.027) and 24 of the 28 carcinomas( P

A model of acute lung injury was reproduced by intravenous injection of endotoxin (700?g / kg) to rabbits. It had been found that the rabbits were in the state of shock, with leukopenia and thrombocytopenia, increased 6 -keto-PGF1? and TXB2, decreased serum ACE and increased permeability of the pulmonary capillaries. Granulocyte sequestration and disturbance in pulmonary microcirculation were found in lungs. A series of changes in epithelial and endothelial cells were also found in both lungs. It was obviously proved that PGE1 had some therapeutic effects in acute lung injury induced by E. coli endotoxin.

The aim of this study was to investigate the effect of Paris saponin I (PS I) on human gastric carcinoma cell growth and apoptosis and to explore the potential mechanisms. The proliferation of SGC7901 cells was monitored by the MTT cell viability assay, while the nuclear morphology of apoptotic cells was assessed by Hoechst 33258 staining. Flow cytometry was performed to analyze the cell cycle progression of propidium iodide (PI)-stained SGC7901 cells and the apoptotic rate of annexin V/PI-stained cells. Western blotting was used to examine the expression of several cell cycle proteins, including cyclin B1 and Cdk1, and the apoptosis-regulated proteins Bcl-2, Bax, cytochrome c, procaspase-9, and procaspase-3. The MTT assay demonstrated that PS I could induce significant dose- and time-dependent inhibition of SGC7901 cell proliferation. Marked morphological changes, including condensation of chromatin, nuclear fragmentation and apoptotic bodies were clearly shown on Hoechst 33258 staining. PSI treatment also resulted in the disruption of the cell cycle at G(2)/M and the induction of apoptosis. Following PSI treatment, the cell cycle-related proteins cyclin B1 and Cdk1 were down-regulated. Expression of the pro-apoptotic protein Bax was increased, while anti-apoptotic protein Bcl-2 decreased. PSI treatment resulted in elevated cytoplasmic cytochrome c and activation of the apoptotic proteases caspase-9 and caspase-3. These data indicate that PS acts as an inhibitor of proli I feration in SGC7901 cells by inducing cell cycle arrest and mitochondria-dependent apoptosis. PSI is a potential therapeutic agent against human gastric carcinoma.

Objective To analyze the association of blood uric acid level with the severity of coronary artery stenotic changes, metabolic syndrome (MS), and its components. Methods A total of 343 individuals ( male 223,female 120) who underwent coronary angiography and had complete data on MS and serum uric acid were collected. The severity of coronary artery disease (CAD) was assessed by the coronary stenesis index (CSI). MS was diagnosed according to the Guideline on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults. Results (1)The mean uric acid level was significantly lower in women than in men [ ( 306.3±76.9 vs 358.9±85.2 ) μmol/L, P＜0.01 ]. The prevalence of MS and its components showed no difference between men and women. (2) The uric acid level in women with 3 components was higher than those with1( P＜0. 01 ) or 2 ( P＜0.05 ) components of metabolic disorders, but not in men. (3) Quartiles of concentration of uric acid were computed. Compared with those in the lowest quartile of uric acid, women in the highest quartile had higher CSI score [ 7.0 (2.5-12.0) vs 2. 0( 0.0-6.0), P= 0. 025 ]. Moreover, the uric acid level was higher in women with multivessel lesions than nonCAD patients [ (327.0±81.9 vs 284.9±78.6) μmol/L, P = 0.033 ]. However, no correlation was found between uric acid level and the severity of coronary artery lesion in men. (4) Logistic regression showed that age (β=0.042, P=0. 007) and dyslipidemia(β=0.836, P=0. 037 ) were the independent risk factors of CAD in men, and hypertension(β=1. 127, P=0.039) and dyslipidemia(β=0.901, P=0.009)in women. Conclusions In women with higher uric acid level, the clustering of metabolic abnormalities was increased, and the coronary artery lesion was more severe. High uric acid level might be a marker of CAD for women.

ObjectiveTo study the expression of insulin-like growth factor Ⅱ mRNA-binding protein 3 ( IMP3 ) and its clinicopathological significance in breast cancer.MethodsThe Maxvision immunohistochemistry was used to detect the expression of IMP3 protein in 103 cases of breast cancer and the adjacent normal breast tissues.Stem-loop real-time RT-PCR was used to detect the expression level of IMP3 mRNA in 30 cases of breast cancer and the matched non-tumor adjacent tissues.The relationship between the expression of IMP3 and the clinicopathological features of breast cancer was analyzed.Results62 cases were infiltrative ductal carcinoma,3cases were invasive lobular carcinoma,9 cases were microinfiltrative intraductal carcinoma,and 29 cases were special type of carcinoma.The difference of IMP3 expression between breast cancer group and normal breast tissue group had statistical significance( t =19.630,P =0.000)by t test.For infiltrative ductal carcinoma patients,IMP3 expression had no significant relation with age,tumor size,lymph node metastasis,histological grade,pTNM stage,ER,PR,or HER-2 ( P ＞ 0.05 ).IMP3 mRNA expression level of was significantly higher in tumor tissues than in the adjacent normal tissues (P ＜ 0.05 ).No significant association was found between the expression of IMP3 and the histological grade,tumor size,lymph node metastasis ( P ＞ 0.05 ).ConclusionIt is possible that IMP3 plays an important role in the generation,progression,invasion and metastasis of breast cancer.

Objective To establish a novel method for detecting circulating tumor cells (CTCs) in phripheral blood of lung cancer patients with high sensitivity and specificity.Methods Experimental study.42 cases of initial treatment patient who underwent resection and diagnosed to be non-small cell lung cancer by biopsy were studied,including 7 patients at stage Ⅰ,9 patients at stage Ⅱ,16 patients at stage Ⅲ and 10 patients at stage Ⅳ.As a control group,20 cases of healthy volunteers were selected.A series of experiments was conducted to determine the efficiency of tumor cells isolation,in which varied concentration (50,100,200,500,1000 cells) of A549 cells spiked into 2 ml peripheral blood drawn from healthy donors.The blood was removed of unwanted erythrocytes by lysis buffer,and made the rest of nucleated cells incubate with anti-EpCAM magnetic beads,then separated and enriched by a specific detector.All epithelia cells were retained on a slide because of a magnetic force and identified by H&E staining protocol.On the basis of cell recovery rate we calculated the sensitivity of tumor cells isolation.20 blood samples taken from healthy individuals were also detected to validate the specificity of this method.Samples of 42 patients with lung cancer were assayed for CTCs detection by above method.The correction of CTCs quantity with the patients' clinical features,for example,ages,gender,clinical stage,tumor size was analyzed in lung cancer patients by chi-square statistics.The correction of recovery cells with the spiked cells were assayed by linear correlation.Results The recovery rate was ranging from 68％ to 82％ by spiking varying numbers of A549 lung cancer cells into 2ml blood samples of healthy volunteers.Regression analysis of number of recovered vs.spiked A549 cells yielded a regression equation of Y =0.6419X + 8.8875.The number of CTCs detected has signification correlate with the cells spiked (R2 =0.9916,P ＜ 0.05),Eighteen of the 42 patients (43％) were found have CTCs in peripheral blood.The detection rate of lung cancer cells was 0 at stage Ⅰ,the detection rate of lung cancer cells was 11.1％ at stage Ⅱ,the detection rate of lung cancer cells was 62.5％ at stage Ⅲ and the detection rate of lung cancer cells was 70％ at stage Ⅳ.The positive rate of CTCs has no signification correlate with ages and gender of patients and tumor size (P ＞ 0.05),has signification with the clinical stage (P ＜ 0.05).None of the peripheral blood samples of the 20 healthy subjects analyzed was found to have CTCs.Conclusions This novel immunomagnetic separation technology is a sensitive and specific method,which provides a new tool allowing for feasible and specific detection of CTCs in lung cancer patients.The level of CTCs increases with the clinical stage and tumor size increased,which has important value to discover the early stage micrometastasis and redefine the clinical stage.But further multicenter and large sample clinical research are needed to confirm its clinical value.
