This study aimed to summarize the diagnosis and treatment of uncommon complications in esophageal and cardiac cancer operations as well as obtain lessons from the failure. Methods:The etiology, clinical diagnosis, treatment, prevention measures, and factors that contribute to the failure of the uncommon complications were analyzed retrospectively. Results: Results showed ten cured cases and eight death cases (except for the reported eight cases). Conclusion:The following conclusions were ob-tained. 1) The complications described in this paper were rare, but they sometimes occur clinically. If wrong treatment was taken, seri-ous consequences would be expected. 2) Once a jet-like bleeding of aortic esophagus avulsion injury occurs, the surgeon must be calm and take proper treatment to successfully patch up the wounds. 3) The right thoracic approach is a new approach to prevent the injury of azygos vein. 4) Patients with anastomotic stoma fistula easily cause a delay in diagnosis if the leakage was wrapped in the inferior phrenic. 5) Taking preventive measures is the key method for the anastomotic aortoesophageal fistula. 6) Occurrence of pulmonary em-bolism after operation should be monitored. 7) Thoracic gastric mediastinal hernia would cause serious consequences if treatment was not taken at a proper time.

Objective To identify risk factors associated with the severity of acute kidney injury (AKI) in-duced by crush syndrome and whether the patient required hemodialysis (HD). Method A retrospective study was designed. Within 19 days after the Chinese Wenchuan earthquake (May 12, 2008), 63 victims (33 men, 30women) of 2139 cases were hospitalized at Mianyang Central Hospital (Siehuau, China) because of crush syn-drome caused by crush injuries. The patients with renal dysfimcfion before the earthquake were excluded. Totally 63 patients with AKI associated with crush syndrome were included in this study and were divided into two groups: group 1, 25 patients, requiring HD (when urine volume <250 mL/d;serum potassium> 6 mmol/L) ; and group 2, 38 patients, without HD. The following data were collected retrospectively for all patients: (1) epidemiological parameters: age, gender, race, time under the rubble, liquid treatmem before being rescued; (2) clinical param-eters: blood pressure, body area crushed, amputation, fasciotomy, blood transfusion, quantity of fluid infusion, urine output in the first 24 hours; (3) initial laboratory data: complete blood count, urine analysis, serum chem-istry, arterial blood gas analysis. Comparisons between the two groups were made using SPSS 10.0. The quantita-tive data and categorical data were analyzed using t tests and χ2 tests, respectively. P -values < 0.05 were consid-ered to indicate significant differences. The significant variables were entered into logistic regression models to de-termine the risk factors for the severity of AK1 in patients with crush syndrome and whether the patient required HD. Results Four significant risk factors with P -values < 0.05 were identified: fasciotomy, cystatin C (Cys C)level, myoglobin (MB) level and lactic acidosis. The odds ratios (95% confidence intervals) were 8.641 (3.027～76.479), 6.956 (3.027～76.479), 5.379 (3.027～76.479) and 4.833 (2.569～32.764), respectively. Conclusions In addition to urine output and potassium levels, we found that four risk factors, namely faseiotomy, Cys C and MB levels, and lactic acidosis, were significanfly associated with the severity of AKI and whether the patient required hemodialysis.

AIMTo investigate the effect of resveratrol on EMMPRIN expression of macrophages.

METHODSHuman monocytic cell line THP-1 cells were co-cultured with EMMPRIN-highly-expressed MCF-7 cells; MMP-9 production was assayed by zymography. THP-1 cells were induced by PMA, expression of EMMPRIN was assayed by Western blotting. Cells were treated with resveratrol or PPARgamma agonist--pioglitazone during differentiation, EMMPRIN expression and MMP-9 activity were assayed. U937 cells were co-transfected with PPARy expression and luciferase-coding reporter vector, then cultured with pioglitazone or resveratrol, the activating capability of resveratrol on PPARgamma was evaluated by measuring the luciferase activity. THP-1 cells were pretreated with PPARgamma antagonist--GW9662 before pioglitazone or resveratrol treatment, then assayed for EMMPRIN expression and MMP-9 production.

RESULTSEMMPRIN expression was greatly increased during the differentiation from monocytes to macrophages; co-culturing with MCF-7 cells significantly increased MMP-9 production by monocytes. Both resveratrol and pioglitazone markedly inhibited EMMPRIN expression during monocytes differentiation. Resveratrol significantly activated PPARgamma and GW9662 greatly decreased the effect of resveratrol on EMMPRIN and MMP-9.

CONCLUSIONEMMPRIN expression is greatly up-regulated from monocytes to macrophages, which may play a role in inducing MMPs production by monocytes/macrophages. Resveratrol can significantly inhibit EMMPRIN expression via activating PPARgamma, which may be the underlying mechanism of its inhibitory effect on MMPs production by monocytes/macrophages.

Clinical reports on cardiac syndrome X (CSX) have been increasing in recent years. In general, CSX does not increase the cardiovascular mortality, but it can affect the patient's quality of life (QOL) and increase the incidence rates of cardiovascular and cerebrovascular events. Although a variety of drugs and therapies have been utilized in the clinical treatment, the management of CSX still represents a major challenge due to its unclear pathogenesis. It is necessary to explore more effective treatment programs. Many attempts have been made on trials of the Chinese medicine (CM) treatment for CSX and proved that CM has a certain advantage in efficacy to improve clinical symptoms and QOL. CM may provide a new approach for the effective treatment of CSX.

OBJECTIVETo evaluate the expression of vascular endothelial growth factor C (VEGF-C) and peroxisome proliferators-activated receptors (PPARgamma) in extrahepatic cholangioadenocarcinoma (EHCAC) and to elucidate its correlation with clinicopathological factors and their significance in prognosis.

METHODSThe expressions of PPARgamma and VEGF-C were detected by immunohistochemistry in 69 cases of EHCAC, 12 cases of non-tumor bile duct epithelium, and their relationship to clinicopathological parameters and follow-up were analyzed.

RESULTSThe positive rate of PPARgamma expression in 69 cases of EHCAC was 59.4%, significantly higher than that in 12 cases of non-tumor bile duct epithelium (0%), (P < 0.01). The positive rate of VEGF-C in 69 cases of EHCAC was 84.1%, also significantly higher than 16.7% in 12 cases of benign bile duct epithelium (P < 0.05). PPARgamma expression was associated with clinical TNM stage and lymph node metastasis. VEGF-C expression was associated with lymph node metastasis. Cox analysis results showed that portal vein and/or hepatic artery invasion, lymph node metastasis and VEGF-C expression were independent prognostic factors of EHCAC (P < 0.05).

CONCLUSIONPPARgamma expression may play an important role during tumorigenesis of extrahepatic cholangioadenocarcinoma. The expressions of PPARgamma and VEGF-C are significantly correlated with the clinicopathological characteristics and biological behavior of EHCAC. Expression of VEGF-C is an independent prognosis factors in EHCAC. The detection of PPARgamma and VEGF-C is valuable for evaluation of prognosis of EHCAC.
