ObjectiveTo investigate the relationship of the polymorphism of endothelial nitric oxide synthase (eNOS), the 27-bp variable number of tandem repeats (VNTR) in intron 4 with essential hypertension (EH) of the northern Han nationality in China.MethodsGenotypes, the level of plasma nitric oxide metabolites (NOx) and the activity of nitric oxide synthase (NOS) of 207 EH subjects and 231 healthy subjects were measured by polymerase chain-reaction (PCR).ResultsThe frequencies of ecNOS4a/a,ecNOS4b/a, and ecNOS4 b/b in the healthy group were 0.43%, 13.42% and 86.15% respectively. The frequency of the b allele was 92.86%, and the frequency of the a allele was 7.14%. While the frequencies of ecNOS4 a/a, ecNOS4 a/b,and ecNOS4 b/b in the EH group were 0.49%, 19.32% and 80.19% respectively. The frequency of the a allele in EH group (n=42, 10.15%) was significantly higher than that in the healthy group (n=33, 7.14%)(P<0.05). The plasma NOx level of the EH group was 70.04±14.68 mol/L, and significantly lower than that 84.09±27.27 mol/L in the healthy group (P<0.05). Similarly, both the plasma TNOS and iNOS activities of the EH group were 35.49±12.8 U/ml and 14.92±7.93 U/ml, and markedly lower than that 41.47±13.2 U/ml and 10.11±6.21U/ml in the healthy group (P<0.05). But the activities of eNOS in the EH group and healthy group were not significantly different (P>0.05).ConclusionThe variations of ecNOS4 gene locus may be responsible for the decrement of plasma NOx, both plasma NOx level and activity of NOS decreases in EH patients, so it may be a genetic susceptibility marker for EH of the Han nationality in China.

Objective To investigate whether systemic inflammatory response syndrome(SIRS) after cerebral infarction is associated with poor outcome and its associated clinical factors.Methods We prospectively studied 500 patients with cerebral infarction.recorded the associated clinical factors on presentation and calculated the mortality at 21 st day.Results There are 85 SIRS patients in 500 patients with cerebral infarction,31 with total anterior cerebral infarction(TACI),34 with partial anterior cerebral infarction(PACI),15 with posterior cerebral infarction(POCI)and 5 with lacunar cerebral infarction (LACI).The frequency of SIRS was positively correlated with mortality rate according to Oxfordshire Commanity Stroke Project(OCSP)subtypes in cerebral infarction patients with fever(Spearman correlation coefficient=1.0:P＜0.001).Single factor analysis showed that the risk factors for both SIRS and mortality of cerebral infarction were as follows:age,infection,48h Chinese Stroke Scale score,48h Glassgow score,OCSP subtypes and dysphagia.Diabetes Was the risk factor for SIRS.but had no effect on mortality.On Cox regression,48h Glassgow score was the sole independent risk factor of outcome.However.if SIRS was included in the formula.P＞0.05.ConclusionsSIRS is the predictor of poor outcome after acute cerebral infarction.It is important to prevent SIRS especially in TACI and POCI.Diabetes is the risk factor for SIBS.but has no effect on mortality.
