Comparison of drug eluting stent implantation with coronary artery bypass surgery in the treatment of patients with chronic total occlusion and multiple vessel disease.
In patients with chronic total occlusion (CTO) and multivessel coronary artery disease, the comparison of surgical and the percutaneous revascularization strategies has rarely been conducted. The aim of this study was to compare long term clinical outcomes of drug eluting stent (DES) implantation with coronary artery bypass surgery (CABG) in the patients with CTO and multivessel disease. ⋯ Our study shows that in patients with CTO and multivessel coronary disease, DES can offer comparable long term outcomes in cardiac death and myocardial infraction free survival in comparison with CABG. However, there is an increased rate of MACCE which results from more repeat revascularizations. Obtaining a complete revascularization is crucial for decreasing adverse cardiac events.

Correlation between coagulation function, tumor stage and metastasis in patients with renal cell carcinoma: a retrospective study.
The coagulation function in carcinoma patients is abnormal, but in renal cell carcinoma the extent and relationships of coagulation function remain unclear. This study retrospectively investigated the relationships between coagulation function, clinical stage and metastasis in patients with renal cell carcinoma. ⋯ Preoperative plasma fibrinogen levels are elevated in patients with renal cell carcinoma with distant metastasis or lymph node metastasis. Potential metastasis is more likely if the tumor size larger than 4 cm. Increased preoperative plasma fibrinogen levels, especially hyperfibrinogenemia, may be an indicator of metastasis.

Silencing of high mobility group A1 enhances gemcitabine chemosensitivity of lung adenocarcinoma cells.
The high mobility group A1 (HMGA1) proteins are architectural transcription factors found to be overexpressed in lung adenocarcinoma. Lentivirus-mediated RNA interference (RNAi) technology is a powerful tool for silencing endogenous or exogenous genes in human cancer cells. Our preliminary study shows that gemcitabine inhibits growth of the human lung cancer cell line SPCA-1 and induces apoptosis, and this effect might link with down-regulation of HMGA1 expression. This study aimed to investigate the chemosensitivity change of the lung adenocarcinoma cells SPCA-1 after HMGA1 inhibition by lentivirus-mediated RNAi. ⋯ Lentivirus-mediated RNA interference of HMGA1 enhanced chemosensitivity to gemcitabine in lung adenocarcinoma cells. The mechanism may be associated with the PI-3K/Akt signal pathway. HMGA1 may represent a novel therapeutic target in lung cancer.

Laparoscopic splenectomy for immune thrombocytopenic purpura at a teaching institution.
High anatomic location, fragility, and generous blood supply of the spleen makes laparoscopic splenectomy (LS) difficult to master, and few patients need splenectomy for benign disorders. The aim of this research was to assess operative outcomes and hematological results of a large series of patients treated with LS for chronic immune thrombocytopenic purpura (ITP) and to determine which clinical variables predict favorable hematological outcome. ⋯ LS is a safe and effective treatment for chronic ITP. Postoperative peak platelet count may serve as a major predictor of long-term response.

Distribution of serum prostate-specific antigen in Chinese healthy men: a population-based study.
The morbidity and mortality of prostate cancer have been increasing rapidly in recent China. There were few studies investigating prostate-specific antigen (PSA) values ranges in the healthy Chinese population. We performed this study to determine the distribution of serum PSA in a large healthy Chinese population. ⋯ The serum PSA level correlates directly with age in Chinese men older than 40 years, not in Chinese men younger than 40 years old. Chinese men have lower PSA level compared with white men above 60 years of age, not in those under 60 years of age.
