In the latter case, it is desirable to be able to vary the level of steering effort. More recently, steering valves have been employed in higher power vehicle steering systems where relatively high pressure fluid from the power steering circuit is employed to assist the steering effort, such as in Jeep vehicles, and in order to allow the driver to select the level of driver effort in a tugboat trailer vehicle. In this type of steering system, the steering valve, or valves, are housed in a steering valve assembly which communicates with both the primary and secondary circuits of the vehicle power steering system.

The above patents all disclose hydraulically operated steering valves which are commonly employed in relatively low vehicle power steering systems to vary the effort of steering required of the driver. Steering valves are well known in the prior art and are shown in U.S. This invention relates generally to vehicle steering systems and more particularly to steering systems having a dual stage steering valve for allowing the operator to select different levels of effort to vary the steering effort. The risk factor of S100B rs1800614 T allele is involved in the development of schizophrenia.1. Subjects with the T allele exhibited a significantly decreased risk of schizophrenia. We found that the S100B rs1800614 T allele is a protective factor for schizophrenia in the Han Chinese population. Multifactor dimensionality reduction (MDR) analysis was performed to evaluate the multifactor risk of genetic susceptibility. We examined rs1800614 genotype distribution in 908 schizophrenia patients and 1036 healthy controls. The aim of this study was to evaluate the effect of S100B rs1800614 on the risk of schizophrenia in Han Chinese.
