OBJECTIVE： To detect the levels of high-sensitivity C-reactive protein （hs-CRP）, interleukin-6 （IL-6）, and tumor necrosis factor- a （TNF- α ） in elderly males with cerebral infarction. DESIGN： Non-randomized current control study. SETTING： Cadre Medical Department, Guizhou Provincial People＇s Hospital. PARTICIPANTS： Forty elderly males （65-89 years old） with cerebral infarction were selected from Cadre Medical Department, Guizhou Provincial People＇s Hospital from February 2004 to December 2006. All patients met the diagnostic criteria of cerebral infarction modified at the 4th National Cerebrovascular Disease Academic Meeting, and were diagnosed on the basis of CT or MRI tests. Furthermore, 35 elderly male inpatients （65-87 years old） without cerebral infarction were selected as the control group. Included subjects provided confirmed consent and did not have heart disease, diabetes mellitus, lipid disorder, acute trauma, infection, rheumatism, or other inflammatory diseases. The study was approved by the local ethics committee. There were no significant differences in age, blood pressure, and lipid levels between the cerebral infarction group and the control group （P 〉 0.05）, and this suggested that the baseline data of both groups were comparable. METHODS： Fasting venous blood was drawn from cerebral infarction patients 24 hours after cerebral infarction attack and from control subjects 24 hours after hospitalization. A latex-enhanced immunoturbidimetric assay and an enzyme-linked immunosorbent assay were used to detect the levels of hs-CRP, IL-6, and TNF- α in the serum. MAIN OUTCOME MEASURES： The levels of hs-CRP, 1L-6, and TNF- α in the serum in both groups. RESULTS： Forty cerebral infarction patients and thirty-five control subjects were included in the final analysis without any loss. Levels of hs-CRP, IL-6, and TNF-α in the cerebral infarction group were significantly higher than those in the control group （P 〈 0.01 ）. CONCLUSION： Levels of serum inflammatory reactive factors are increased in elderly males with cerebral infarction.展开更多

Blood tests for total testosterone （TT） and sex hormone-binding globulin （SHBG） were performed, and the aging male symptoms （AMS） questionnaire was conducted in a randomly selected cohort composed of 944 Chinese men aged 40 to 79 years from nine urban communities. Three sexual symptoms （decreased ability/frequency of sexual activity, decreased number of morning erections, and decreased libido） were confirmed to be related to the total and free testosterone levels. The thresholds for TT were approximately 12.55 nmol l^-1 for a decreased ability/frequency to perform sex, 12.55 nmol l^-1 for decreased frequency of morning erections, and 14.35 nmol l^-1 for decreased sexual desire. The calculated free testosterone （CFT） thresholds for these three sexual symptoms were 281.14, 264.90, and 287.21 pmol l^-1, respectively. TT 〈13.21 nmol l^-1 （OR =1.4, 95%Ch 1.0-1.9, P= 0.037） or CFT 〈268.89 pmol l^-1 （OR - 1.5, 95%Ch 1.1-20, P=0.020） was associated with an increase in the aforementioned three sexual symptoms. The prevalence of LOH was 9.1% under the criteria, including all three sexual symptoms with TT levels 〈13.21 nmol l^-1 and CFT levels 〈268.89 pmol l^-1. Our results may improve the diagnostic accuracy of LOH in older men.展开更多

It is believed that the peptide plays an important role in the reg- ulation of blood pressure, blood volume, and sodium balance. Because in vitro studies have reported that natriuretic peptides are directly released from cardiomyocytes in response to myocardial ischemia , it has been proposed that their circulating levels are relevant to sub- sequent risk of cardiovascular diseases （CVDs） other than heart failure.展开更多
