Background: To investigate the expression level and its clinical significance of the multi-drug resistance (MDR) associated protein in lung cancer specimens.
Methods: The expression levels of Pgp, MRP, GST-π and TopoII of MDR associated protein were detected in 60 lung cancer samples and 30 paracancerous tissues by S-P immunohistochemistry method.
Results: The positive rate of Pgp, MRP, GST-π and Topo II in the lung cancer tissues was 40.0% (24/60), 61.7% (37/60), 45.0% (27/60) and 81.7% (49/60) respectively, which was significantly higher than those in paracancerous tissues (P < 0.01). No significant correlation was observed among the expression of multi-drug resistance-related protein and TNM staging, pathological type, cell differention and lymph node metastasis status (P > 0.05).
Conclusions: Lung cancer has overexpression of multi-drug resistant-related genes during the oncogenesis. Combined detection of these genes may be useful for guiding the lung cancer chemotherapy.

Background: The prognostic value of Chlamydia pneumoniae (Cpn) infection in postoperative lung cancer patients remains unclear. This study aimed to evaluate the association between Cpn infection and survival in lung cancer patients.
Methods: This study included 309 newly diagnosed primary lung cancer patients from three hospitals in Fuzhou, China.

An ideal chemotherapeutic agent damages DNA, specifically in cancer cells, without harming normal cells. Recently, we used Box A of HMGB1 plasmid as molecular scissors to produce DNA gaps in normal cells. The DNA gap relieves DNA tension and increases DNA strength, preventing DNA double-strand breaks (DSBs).

Trousseau's syndrome is a thromboembolic disorder associated with malignancies, with cerebral infarction and hemorrhage representing common central nervous system complications in patients with cancer. This report details the diagnosis and treatment of a patient with gastric adenocarcinoma at our institution who concurrently developed cerebral infarction and subarachnoid hemorrhage. We performed a comprehensive literature review in the Wanfang and PubMed databases, searching for relevant studies on Trousseau's syndrome, cerebral embolism, and subarachnoid hemorrhage.
