Epithelial-mesenchymal transition plays an important role in the development and progression of endometriosis. Mesenchymal-epithelial transition is involved in forming localized lesions of endometriosis, while EMT is involved in the injury, repair and fibrosis induced by local inflammation of endometriosis and the process of cell invasion and metastasis. The studies of signal transduction pathway and related proteins of epithelial-mesenchymal transition in the process of endometriosis may provide new targets for diagnosis and treatment of endometriosis.

We report the case of a 41-year-old Chinese woman with Behçet's disease (BD) complicated by acute myocardial infarction, requiring inotropic and ventilatory support. Angiography showed critical left anterior descending coronary artery stenosis, a blocked left subclavian artery and left carotid artery stenosis. The patient was successfully treated with a high dose of immunosuppressants, standard anti-ischaemic therapy and percutaneous coronary intervention. Although life-threatening, coronary arteritis is a treatable manifestation of BD. We suggest that the diagnosis of coronary arteritis be considered in patients with BD who present with chest pain. Involvement of other arteries should also be looked out for in these patients.

OBJECTIVETo summarize current understanding of the roles of anti-inflammatory and proinflammatory mechanisms in the development of atherosclerosis and acute coronary syndrome and to postulate the novel concept of inflammation stress as the most important factor triggering acute coronary syndrome. Moreover, markers of inflammation stress and ways to block involved pathways are elucidated.

DATA SOURCESA literature search (MEDLINE 1997 to 2002) was performed using the key words "inflammation and cardiovascular disease". Relevant book chapters were also reviewed.

STUDY SELECTIONWell-controlled, prospective landmark studies and review articles on inflammation and acute coronary syndrome were selected.

DATA EXTRACTIONData and conclusions from the selected articles providing solid evidence to elucidate the mechanisms of inflammation and acute coronary syndrome were extracted and interpreted in the light of our own clinical and basic research.

DATA SYNTHESISInflammation is closely linked to atherosclerosis and acute coronary syndrome. Chronic and long-lasting inflammation stress, present both systemically or in the vascular walls, can trigger acute coronary syndrome.

CONCLUSIONSInflammation stress plays an important role in the process of acute coronary syndrome. Drugs which can modulate the balance of pro- and anti-inflammatory processes and attenuate inflammation stress, such as angiotensin-converting enzyme (ACE) inhibitors/angiotensin II receptor blockers, statins, and cytokine antagonists may play active roles in the prevention and treatment of acute coronary syndrome when used in addition to conventional therapies (glycoprotein IIb/IIIa receptor antagonists, mechanical intervention strategies, etc).

Clinical remission has been the therapeutic goal of Crohn's disease treatment for many years. While it has helped to ameliorate the symptoms, this treatment strategy has not brought about significant changes in the need for abdominal surgery in the natural history of Crohn's disease. The advent of biological agents (biologics) has shown that it is possible to induce and maintain mucosal healing in a significant proportion of treated patients. Data is also emerging to show that this has translated to fewer instances of hospitalisation and surgery for these patients. This is a paradigm shift in the therapeutic goal of Crohn's disease treatment.

Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis (SAP) in multiple organ injury is a hotspot in the surgical field. In clinical practice, the main complicated organ dysfunctions are shock, respiratory failure, renal failure, encephalopathy, with the rate of hepatic diseases being closely next to them. The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis, but also develop into hepatic failure and cause patient death. Its complicated pathogenic mechanism is an obstacle in clinical treatment. Among many pathogenic factors, the changes of vasoactive substances, participation of inflammatory mediators as well as OFR (oxygen free radical), endotoxin, etc. may play important roles in its progression.

OBJECTIVETo investigated the involvement of pulmonary function impairment in ulcerative colitis (UC), to explore a scientific basis for the Chinese medicine (CM) theory of exterior-interior correlation between Lung (Fei) and Large intestine (Dachang).

METHODSTotally 120 patients with a diagnosis of UC were recruited and the demographics, clinical data, and blood samples were collected. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) concentrations were measured. Every patient accepted pulmonary function test and took chest radiograph (CXR).> RESULTS: Pulmonary function abnormalities were present in 72 of 120 patients. The median (interquartile range) vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV), carbon monoxide diffusion capacity (DL) of lung, total lung capacity (TLC) and functional residual volume (FRV) were decreased in distal UC and pancolitis compared with ulcerative prochitis (P <0.0005). Male patients had increased VC, FEV/FVC, and residual volume (RV)/TLC compared with female (P <0.0005), but decreased DLand carbon monoxide iffusion capacity (K) of lung/alveolar ventilation (P <0.0005). Age was strongly correlated with RV (Spearman rank correlation coefficient (rs)=-0.57,P <0.0001), and RV/TLC (rs=0.48,P<0.0001). Age was also correlated with FEV/FVC (rs=-0.29, P=0.001), forced expiratory flow in 75% vital capacity (FEF75%, rs=-0.20, P=0.03), DL(rs=-0.21, P=0.02), TLC (rs=-0.25, P=0.006), and FRV (rs=-0.28, P=0.002). The course of disease was correlated with FEF75% (rs=-0.18, P=0.049) and K(rs=-0.19, P=0.036). Chest radiograph abnormalities were presented in 38 of 120. Pulmonary symptoms were presented in 10 of 120. Other extraintestinal complications were presented in 21 of 120.

CONCLUSIONSPulmonary function impairment was more frequently than other extraintestinal complications in UC patients, which may be affected by sex, age, extent and course of disease. These results may be a scientific basis for the theory of exterior-interior correlation between Lung and Large intestine.

OBJECTIVETo investigate the effect of enteral nutrition(EN) on liver function and inflammatory response after abdominal operation in patients with liver dysfunction.

METHODSA prospective multicenter study was conducted. Patients requiring EN for at least 5 days after abdominal surgery with at least 1 abnormal liver function index were included. After operations, EN suspensions(TPF-FOS) were administered for 5 days after the return of bowel function with targeted content of 125.52 kJ(30 kcal)·kg(-1)·d(-1) maintained for a minimum of 3 days. Levels of serum pre-albumin, C-reaction protein(CRP), and liver function index were measured and the incidence of systemic inflammatory response syndrome(SIRS) was recorded before operation and 6 days after EN. Occurrence of gastrointestinal discomfort was monitored during the treatment.

RESULTSNo statistically significant difference was found in pre-albumin between preoperative level and post-EN level[(175.94±71.79) mg/L vs.(192.22±91.26) mg/L, P=0.162]. Patients with abnormal level of γ-glutamyl transpeptidase were less after EN compared to the preoperative period(30 vs. 40, P=0.041), as was total bilirubin (3 vs. 9, P=0.034). No significant differences in other indices of liver function were found. Total bilirubin and direct bilirubin decreased after EN support(P=0.000 and P=0.015, respectively). CRP was notably reduced after EN support [(48.74±65.16) mg/L vs.(25.79±23.63) mg/L, P=0.009] and the incidence of SIRS largely declined after EN support(19.0% vs. 10.3%, P=0.059). The incidence of gastrointestinal discomfort was 22.4% on postoperative day 1 and declined to 19.0% on postoperative day 5.

CONCLUSIONFor patients with liver dysfunction, enteral nutrition support with TPF-FOS after abdominal operation can reduce inflammatory response, improve liver function, and maintain serum protein level.

BACKGROUND/AIMS: Inflammation plays a key role in ischemic acute renal failure (ARF). The present study investigated the infiltration of macrophages in the early phase of ischemic ARF in mice. METHODS: Ischemic ARF was induced by renal clamping for 22 min, while the control mice underwent sham surgery (no clamping). The serum creatinine and blood urea nitrogen (BUN) levels were measured in the control and post-ischemia mice. Immunofluorescence staining was used to measure the number of CD 11b-positive cells in the kidney tissue sections to determine the amount of post-ischemic macrophage infiltration. Lipo-Cl2MBP (clodronate) for macrophages depletion was injected via a tail vein 5 d before ischemia induction and again 2 d before ischemia induction. RESULTS: The study found that the post-ischemia mice had higher levels of serum creatinine and BUN at 16 and 24 h compared to the controls. Immunofluorescence staining showed there were more macrophages in the post-ischemic tissue at 2, 8, 16 and 24 h compared to the control tissue, and that most of these macrophages were located in the outer medulla. The mice treated with clodronate prior to ischemia induction were found to have lower levels of serum creatinine compared to those mice that weren't treated with clodronate. CONCLUSIONS: There was significant infiltration of macrophages from the early phase of ischemic ARF, and this peaked at 16-24 h. Macrophage depletion using clodronate was protective against ischemic ARF.
