Objective To investigate the relationship between serum homocysteine ( HCY) level and cardio/cerebrovascular disease. Methods Serum level of HCY in patients with cardio/cerebrovascular disease was determined by applying enzymatic cycling assay, and the test results were compared with those of 100 normal controls (healthy control group). Results The serum HCY level of cardio/ cerebrovascular disease group was significantly higher than that of healthy control group. Conclusion Hyperhomocysteine (HHCY) is a risk factor for cardio/cerebrovascular disease, and its level is increasing with severity of coronary heart disease (CHD). The types of cerebrovascular disease were not associated with serum level of HCY.

Objective To evaluate the serum rocalcitonin(PCT) determination in the diagnosis of emergency patients with fever . Methods 120emergencypatientswithfeverwereenrolledinthestudy,whoseserumsamplesweretestedbyusingelectrochemilu‐minescence immunoassay for PCT concentrations ,at the same time white blood cells(WBC) count and C reactive protein(CRP) were also determined .Bacterial culture results were used as gold standard for the diagnosis of bacterial infection .WBC>10 .0 × 109/L,CRP>10mg/L,PCT>0.5μg/Lwerethejudgmentcriteriafortheevaluationofthoseindicators.Results 73casesofpatients′bacteria culture results were positive ,47 patients′bacteria culture results were negative;63 cases of patients were with PCT ,WBC and CRP levels elevated at the same time;2 patients′WBC count elevated ,while PCT and CRP concentrations did not ;6 patients′serum PCT concentrations increased ,while WBC and CRP levels didn′t ;4 patients′serum PCT and CRP concentration increased , while WBC count didn′t ;35 patients′PCT ,WBC and CRP kept at low levels .Conclusion Serum PCT concentration could be used as an auxiliary diagnosis indicator in the diagnosis of emergency patients with fever .

Objective To discuss the clinical value of high sensitivity C‐reactive protein(hs‐CRP) ,fibrinogen(Fib) and D‐dimer (D‐D) measurement for patients with acute myocardial infarction(AMI) before and after the treatment with the anticoagulation and thrombolysis therapy .Methods 110 patients with AMI were recruited in the study and the plasma hs‐CRP ,Fib ,D‐D and myocardi‐al damage markers were measured before and after the treatment .Results 66 of the 110 patients′plasma hs‐CRP ,Fib ,D‐D concen‐trations elevated(higher than the threshold) before treatment and after treatment within 24 h ,while 44 patients′plasma hs‐CRP , Fib concentrations increased ,but D‐D didn′t .Conclusion The measurement of hs‐CRP is helpful for the diagnosis and treatment of AMI .Hs‐CRP is another good myocardial injury marker ,and the plasma hs‐CRP concentration after treatment for 24 -48 h could reflect the severity and prognosis of AMI better than after treatment within 12 h .Fib decreases relatively slowly after the treat‐ment ,so it cannot be used for curative effect observation for AMI patients;D‐D concentration dosen′t have the determined negative predictive value for the diagnosis of AMI ,so it cannot be used as screening out indicator for AMI ,but D‐D concentration can be used as therapeutic effect monitoring indicator for AMI patients with D‐D positive .
