OBJECTIVE To assess the hazards at an early phase of the growing epidemic of deaths from tobacco in China. DESIGN Smoking habits before 1980 (obtained from family or other informants) of 0.7 million adults who had died of neoplastic, respiratory, or vascular causes were compared with those of a reference group of 0.2 million who had died of other causes.(More)
We report 5 cases of chronic myelogenous leukemia (CML) and 1 case of acute myeloid leukemia (AML) with the dual presence of t(9;22) and inv(16). The 6 patients were 5 men and 1 woman with a median age of 42.5 years. All cases were BCR-ABL+ with p210 products detected in all CML cases and a p190 product detected in the AML case. An increase in bone marrow(More)
BACKGROUND To investigate the role of Cullin1 (Cul1) in the development of breast cancer, we examined the expression of Cul1 in breast cancer tissues and analyzed the correlation between Cul1 expression and clinicopathologic variables and patients survival. PATIENTS AND METHODS We evaluated the Cul1 expression by immunohistochemistry using a tissue(More)
Infiltration of hematogenous lineage cells into the central nervous system (CNS) was investigated in the twitcher mouse, a murine model of globoid cell leukodystrophy in human. The hematogenous cells were selectively labeled following intraperitoneal injection of rhodamine isothiocyanate (RhIc). The frequency of detecting Rhlc-labeled cells (Rhlc+ cells) in(More)
BACKGROUND From March 1986 through May 1991, we conducted a randomized nutritional intervention trial, the General Population Trial, in Linxian, China, a region with epidemic rates of squamous esophageal and adenomatous gastric cardia cancers. We found that participants who received selenium, beta-carotene, and vitamin E had significantly lower cancer(More)
BACKGROUND Telomerase, a ribonucleoprotein complex that maintains telomeric DNA, has been detected in 67-93% of prostate carcinomas by telomeric repeat-amplification protocol assay (involving polymerase chain reaction). One study used in situ hybridization in nine patients; however, to date, no immunohistochemical results have been published. METHODS From(More)
BACKGROUND Rates of oesophageal/gastric cardia cancer in Linxian, a rural county in north central China, are among the world's highest, but the risk factors are not well understood. METHODS A nested case-control study of oesophageal and stomach cancers was conducted within a cohort of 29,584 adults who participated in a randomized nutrition intervention(More)
A case-control study focusing on the role of single food items was undertaken in the Heilongjiang area, 241 patients with histologically verified stomach cancer and an equal number of controls (with non-neoplastic diseases) matched by age, sex and area of residence being interviewed during a 2-year period. Questions asked covered economic status,(More)
BACKGROUND Coronary stents prevent constrictive arterial remodeling but stimulate neointimal hyperplasia. Stainless steel induces a metallic foreign body reaction, which is absent for titanium. The hypothesis of the present study was that titanium renders the stent surface biologically inert, with reduced platelet and fibrinogen binding. METHODS AND(More)
