Human colon epithelial cells secrete an array of proinflammatory cytokines that includes IL-8, MCP-1, GM-CSF, TNF alpha and IL-6. This response may serve to attract neutrophils and macrophags to the site of infection. In addition to IL-8 and MCP-1, the chemokine family contains other members, which, alone or in combination, can recruit and/or activate inflammatory and lymphoid cells. In this study, we asked whether colon epithelial cells express a broader array of chemokines than previously described. The colon epithelial cell line, Caco-2, was stimulated for 3h with IL-1 alpha, or was infected with Salmonella dublin. RNA was extracted and chemokine mRNA levels were determined by quantitative reverse transcription-PCR using internal RNA standards. Ex pression of GRO alpha, GRO beta, GRO gamma and IP-10 increased by bacterial infection or IL-l alpha stimulation. These data strongly support the notion that epithelal cells are an important and integral component of the host's natural immune system.

OBJECTIVE: To observe the correlated serum inflammatory factor and cytokine changes in patients with coronary stent implantation, and to explore the significance of these changes.METHODS: Chinese Journal Full-Text Database was retrieved with search terms of coronary artery disease, percutaneous coronary interventions, inflammation, intimal hyperplasia, apoptosis and platelet-derived growth factor from 1995 to 2008. The language was restrained Chinese. A total of 17 literatures were collected, which concerns the changes of correlated inflammatory factor and cytokine levels and its significance. The literatures were sorted according to research object, experimental grouping,sample collection, assay method, experimental result, as well as experimental conclusion. Simultaneously, the patients received coronary stent implantation was analyzed to explore the significance of inflammatory factor and cytokine changes.RESULTS: The dynamic changed serum inflammatory factor and cytokine in patients with coronary stent implantation may be associated with the following mechanisms:①Endothelial cells were easily damaged in the balloon dilatation or stent implantation,therefore, inflammatory mediators or inflammatory factors were exposed to blood circulation, which stimulating neutrophilic granulocytes and up-regulating leukocyte adhesion molecule CD11b expression. ②Many stimulus could arise nuclear factor induced inflammatory reaction, produce interleukin 6, and stimulate C-reactive protein generation. ③The level of angiotensin Ⅱ increased at several days following stent implantation, and heightened with time prolonged, the proliferation of angiotensin Ⅱ was regulated by platelet-derived growth factor. By increasing the expression of endothelin, the synthesis of endothelin was accelerated, the proliferation and migration of vascular smooth muscle cells was promoted, which ultimately resulted in atherogenesis, balloon damage also involved in this process, which may be one of the mechanisms of restenosis.CONCLUSION: The changes of correlated inflammatory factor and cytokine can be served as inflammatory reaction indexes;moreover, soluble CD40 ligand, C-reactive protein and matrix metalloproteinase 9 may be associated with in-stent restenosis.

The 8 kDa antigenic protein of Clonorchis sinensis was partially purified by ammonium sulfate precipitation and subsequently by a column chromatographic steps. The purified protein was separated into 7 and 8 kDa protein bands through SDS-tricine gel electrophoresis, while the protein was found to migrate to a 8 kDa band in 7.5-15% SDS-PAGE. The molecular weight of the antigen was estimated to be 110 kDa by Superose 6 HR 10/30 gel filtration. The purified antigen strongly reacted with the human sera of clonorchiasis. The hyperimmune sera of BALB/c mice immunized against the 8 kDa protein were reacted with both the crude extract and the excretory-secretory product of adult worms, but not with the metacercarial extract. Immunohistochemical staining demonstrated that the protein was distributed to the tegument and subtegumental cells and also to the seminal receptacle. The present findings suggest that the 8 kDa protein is a partition of the multicomplex protein originating from various organs of adult C. sinensis, and that it is composed of several 7 and 8 kDa proteins.

PURPOSE: To investigate the coronary angiographic findings of left atrial thrombi associated with mitral stenosis. MATERIALS AND METHODS: In 98 patients who had undergone coronary angiography and in whom the presence of left atrial thrombi was confirmed by surgery or repeated transesophageal echocardiography, evaluated the pattern, origin and location of abnormal vasculature suggestive of left atrial thrombi such; abnormalities included neovascularity, staining, dye collection and fistula. RESULTS: Abnormal vasculature was observed in 70 patients (71.4%). It arose from the left circumflex artery in 66 patients (including the sinus nodal branch in four), the right coronary artery in 14 (including the sinus nodal branch in 7 and conal branch in 2), the left anterior descending artery in one, and the left main coronary artery in one. The patterns of abnormal vasculature arising from the left coronary artery were fistula in 50, dye collection in 32, staining in 29 and neovascularity in 24; those arising from the right coronary artery were fistula in four, dye collection in two, staining in four and neovascularity in nine. Abnormal vasculature located at the anterior third of the left atrium in 50 cases, the middle in 20, and the posterior region in 12. CONCLUSION: The abnormal vasculature suggested by left atrial thrombi most commonly arose from the left circumflex artery and was located at the anterior one-third of the left atrial cavity. Fistula was the most common finding of left atrial thrombi, and for that these detection of the abnormal vasculature thrombi give rise to, selective coronary angiography was the useful modality.

UNLABELLED:
OBJECTIVE To investigate the time-dependent expression of c-jun during the healing of incised wound in mice skin.
METHODS:
The expression of c-jun in different stages after the incised wound were detected by immunohistochemistry and Western blot.
RESULTS:
There was a low level expression of c-jun in normal mice skin. Expression of c-jun was mainly detected in neutrophils from 3 h to 12h after injury. The c-jun positive cells were almost mononuclear cells (MNCs) and fibroblasts between 1 d and 5 d after injury. The c-jun positive cells were mostly fibroblasts between 7 d and 14 d after injury. The ratio of the c-jun positive cells increased in the wound specimens from 3 h to 12 h, peaked at 12 h, declined partially from 1 d to 5 d, and reached the peak secondly at 7 d, then decreased from 10 d to 14 d. The expression of c-jun was observed throughout the wound healing stages by Western blot with two peaks occurring at 12 h and 7 d after injury.
CONCLUSION
The c-jun may play a potential role in inducing apoptosis of neutrophils, MNCs and fibroblasts during skin wound healing, and it may be used as the marker for wound age determination.

Insertion of intravascular catheters may be the most common procedure in neonatal intensive care units. One of these kinds of catheters, umbilical venous catheter is generally used for the small and sick neonates. But the indwelling umbilical venous catheter can cause many complications. The most common complication is thrombus formation in the lumen of the catheter. Neonatal thrombosis has symptomatic or asymptomatic clinical manifestations, which may have serious complications in case of intracardiac thrombosis. In our experience, the infant who has no symptom of thrombosis was treated with low dose aspirin and warfarin for right atrium thrombosis caused by umbilical venous catheterization. So, we report a case of right atrium thrombosis following umbilical catheterization in neonatal intensive care units.

BACKGROUND: Identifying the donor and isolation-related factors during the islet isolation would be greatly helpful to improve the result of human islet isolation for successful clinical islet transplantation. METHODS: Sixty-nine pancreata from cadaveric donors were isolated with standard protocol and analyzed to identify the donor factors and isolation variables for successful isolation. Islet isolations recovered > or = 100,000 Islet Equivalent (IEQ, n=53) were compared to islet mass less than 100,000 IEQ (n=16). RESULTS: The mean islet recovery was 216.0 x 10(3) +/- 173.7 x 10(3) (IEQ) before purification and 130.6 x 10(3) +/- 140.2 x 10(3) (IEQ) after purification. Mean purity was 54 +/- 31%. Mean age of donor was 31.2 +/- 13.2 year and mean cold ischemic time was 6.9 +/- 6.2 hour. Quality of isolated islets was acceptable in terms of bacterial culture, viability and secretory function in vitro and in vivo. In univariate analysis on successful isolation, status of pancreas was the only significant factor and sex, duration of collagenase expansion and digestion time were marginal factors. Stepwise multivariate logistic regression analysis showed donor sex, status of pancreas and digestion time were significant factors for the successful islet isolation. CONCLUSION: This study confirms some donor factors and variables in isolation process can influence the ability to obtain the successful isolation of human islet. Enough experiences and pertinent review of donor and isolation factors can make islet isolation successful, supporting the clinical islet transplantation without spending of cost.
