According to magazine of foreign authoritative science newest report: The researcher of center of medicine of American Colombia university passes the test to mice recently, discover human body cancer of the stomach pathogeny comes from the likelihood to do a cell at marrow. And before the hypothesis of medical bound is the cancer of the stomach that the reason such as pylorus helix bacili causes, be by former mutation causes a constituent dry cell directly. New discovery makes scientists examine the origin of gastric ministry tumour and development mechanism afresh, consider to improve then or develop new cancer of the stomach to treat a method.

Cancer of the stomach points to happen in the stomach the malignant tumor of epithelial tissue, it is a kind of main deadly cancer, it is in the developing country kill You Lie. It is with our country exemple, cancer of the stomach is the common disease that endangers people health badly, first what mortality resides all sorts of malignant tumor high. This disease all can happen in any ages, be in the majority to 60 years old with 50 years old, of incidence of a disease of male and female than for 3.2: 1 to 3.6: 1; Clinical and inchoate 70% above are without a symptom, in obstacle of block of haemorrhage of ache of terminal occurrence epigastrium, enteron, perforative, pylorus, angular, lack of power, metabolization and cancer are swollen the corresponding symptom that diffuses to transfer and be caused. In theory of doctor of traditional Chinese medicine, cancer of the stomach belongs to " of " Fu Liang, " " of a place of strategic importance of choke of painful " of gastral cavity of accumulative " , " , " and " stomach turn over the category such as " .

About 15 years ago, investigator affects cancer of the stomach and the pylorus helix bacili that cause ulcer connection to rise, consider as it to cause chronic inflammation, thereby abet the occurrence of cancer cell and spread. Majority investigator thinks now, the cell of inflammation may stimulate the epithelial dry cell of gastric ministry wall, make they develop cancer cell. But investigator publishs recently " science " the report on the magazine, the likelihood that causes cancer finally is not epithelial, wall of repair stomach ministry comes before " of " be recruited however, result from medullary dry cell.

It is to analyse medullary dry cell in cancer of the stomach the effect that has, the JeanMarieHoughton that by university of American hemp province Worcester divides school doctor institute one, work now the TimothyWang at Colombian university of new York state and the group that work in the same place to be comprised together, after using bacili of helix of stomach of cat of a kind of infection, gastric ministry appears the small rat of the change of symptom of infection of bacili of helix of similar mankind pylorus, develop research at this point. Investigator destroys the marrow of small rat through some kind of radiate first, make its affect bacili of feline stomach helix next, the transplanting of medullary dry cell that will marked through gene project again arrives inside their body. After discovery is affected about 20 weeks, on the wall that the medullary cell that is marked begins to combine a stomach. They restore to grow in gastric mucous membrane, a few cells that split up appear distortion, appearance and afterbirth of inchoate cancer attenuate are similar, and ceaseless hyperplasia forms tumor finally.

Study the result of this one research that the group obtains, for encourage of " chronic inflammation the theory of " of cancer of the stomach provided further support, bring about cancer " for " dry cell the formulation of this still open to question sex provided evidence, although expert of a few dry cells does not believe medullary dry cell,be in this one experiment the effect that has. Anti emphasizes, investigator did not give out clearly the volume that medullary cell causes the possibility that epithelial cancer changes gastric wall.

This paper of Houghton research group, the likelihood still can inspire a nice research train of thought. The EmadEl-Omar of helix bacili expert that model heart of city of Er of dimension of American Tennessee Nash compares university college of medicine says: "Their working open field of new research of mechanism of cancer of the stomach. "The EmadEl-Omar of helix bacili investigator of university of British A Bai Ding thinks " the notional " that this is a novelty really, it will make people " more the germ that ponders over " cancer of the stomach hard.
