Milk consumption and lactose intolerance in adults.

Objective: To investigate relations between milk consumption and lactose intolerance (LI) in adults and to explore the effect of milk consumption on lactase activity.

Methods: Total of 182 subjects aged 20-70 years were recruited and interviewed by questionnaires, and their accumulative cow's milk intake (AMI) was calculated. LI was evaluated by hydrogen breath test (HBT).

Effects of a regional Chinese diet on proliferation of human esophageal cancer cell line Eca-109 by a sero-physiology method.

Esophageal squamous cell carcinoma (ESCC) is prevalent in Yanting (YT) country located in southwestern China. Residents in the YT region have an unusual diet pattern and the role of the YT diet on the risk of ESCC is still uncertain. The present study was to examine the possible effects of sera from rats fed with the YT diet on proliferation of human esophageal cancer cell line Eca-109 by means of a sero-physiology approach.

Effects of a regional Chinese diet and its vitamin supplementation on proliferation of human esophageal cancer cell lines.

Objective: To study the effects of a local diet popular in Yanting region (YT diet) on the proliferation of two human cell lines (Eca-109 esophageal squamous cell carcinoma line and HL7702 normal liver epithelial cell line) in rats by a sero-physiological approach.

Methods: Male SD rats were divided into six groups and fed respectively with a conventional diet and the YT diet (one of the five experimental diets) supplemented with two vitamin mixtures (Mix. 1: vitamins A, E, and folic acid; Mix.

[Study on ameliorating measures for lactose intolerance to milk].

Objective: To find out the diet measurements for alleviating symptoms of lactose intolerance when people had had a drink of milk.

Methods: Eight lactose intolerance (LI) subjects suffering from watery diarrhea were selected from 38 subjects by using hydrogen breath test (HBT) joined the test of drinking cow's milk along with various other foods designed by orthogonal trial. The 100 healthy college students were selected to observe symptoms after they ingested 25 g milk powder in different manners.

Risk factors for esophageal cancer: a case-control study in South-western China.

Esophageal cancer is a crucial cancer in China. Yanting in Sichuan Province was a key area with highest esophageal cancer mortality in China, but little evidence on esophageal cancer risk factors has been reported for this area and the etiology remains unclear. To clarify risk factors, a 1:1 matched case-control study was conducted.
