[Preparation and characterization of a polyclonal antibody against human Fibrocystin-L].

Aim: PKHDL1 (the gene for Polycystic Kidney and Hepatic Disease Like-1) had been recently identified, but characteristics of the gene product, Fibrocystin-L (FPC-L), still remain unknown. We therefore produced a rabbit polyclonal antibody hFL-Np to explore the cellular characteristics of this novel protein.

Methods: Based on the hydrophobic/hydrophilic analyses, chose a cDNA fragment which encodes 633L-768K amino acids of the FPC-L and amplified it by RT-PCR.

Age scope of high-risk population for esophageal cancer in Ci county.

Aim: To define the age scope of high-risk population for esophageal cancer (EC) in Ci county.

Methods: The results of endoscopic examination of 2 013 subjects, cytological screening of 16 763 persons and records of 9 265 patients with EC were analyzed by Ridit methods, the standard age group was 45-49 year group.

Results: The average age of patients with moderate esophageal epithelium dysplasia by endoscopic examination was 53.

Field population-based blocking treatment of esophageal epithelia dysplasia.

Aim: To confirm the value of blocking treatment by zenshengping (ZSP), a Chinese herb composite, and Riboflavin for esophageal epithelia dysplasia cases screened out in high risk area in northern china by exfoliative balloon cytology (EBC), so to reduce the incidence rate of esophageal cancer(EC).

Methods: Esophageal epithelium dysplasia cases including mind esophageal epithelium dysplasia (MEED), stage one severe esophageal epithelium dysplasia (SEED I), and stage two severe esophageal epithelium dysplasia (SEED II) were screened out from people aged 40 years and older in the high risk area of Chixian. These cases were randomly divided into a treatment and control group.
