翻译分别如下：According to the results of research which had been published,the connection between gene X and the risks of cancer morbidity was contradictory.However,the connection between gene A(or B)and the probabilities of cancer morbidity was still uncertain.
Methods:In order to know better about the effects among the genes A and B and the occurrence rate of global cancers.
These results of research made it clear that there was no prominent connection between the cancer morbidity and the genes A（and B）,and this kind of phenomenon also indicated function X as a node that needed to be verified or combined with functional researchs.
The cancer is the worldwide problem of public health and it is one of the uppermost deadly reasons.However,due to all kinds of reasons,it is very difficult to discern the susceptibility genes.
The obesity has been found that it could increase the probabilities of cancer morbidity.
And there was an evidence indicating that it might play a vital role in the occurrence and development of human cancers.
Therefore,the connection between genes A and B and cancers needed to be investigated further.
During the investigation,the former investigation report between genes A(and B) and all of the cancers was analysed synthetically.
In conclusion,as what form 2 shows.When we put the all of the qualified researchs into the analysis of Meta,we observed that genes A and B didn`t have any occurrence rate which would have an effort on cancers.
And on the basis of the specific cancers,different races,different types of resources,different methods of checking and different sizes of sample plate,we evaluated the polymorphism of genes A and B in order to draw a valid conclusion which was about the potential connection between genes A and B and the occurrence rate of cancers.
From the clue of epidemiology,it showed that the overweight and the obesity would increase the risks of cancers.
