Objective To analyse correlated risk factors of evolving cerebral infarction(ECI).Methods The follow data was recorded in the acute cerebral infarction (ACI)cases when they were admitted :sex,age,systolic blood pressure(SBP),diastolic blood pressure(DBP),history of disease (diabetes mellitus,hypertension,hyperlipidaemia,cerebral infarction,hyperuricemia or smoking).The following examinations or determinations were done,including:white blood cell count (WBC),platelet count (PLT),blood gluconate(GLU),PT-INR,fibrinogen(FG),TT-INR,APTT-INR,C-reactive protein(CRP),D-dimer(D-D),products of fibrin degradation(FDP),anti-thrombin Ⅲ(ATⅢ),apolipoprotein A(apoA),apolipoprotein B(apoB),blood urea nitrogen(BUN),creatinine(CR),triglyceride (TG),high density lipoprotein (HDL),low density lipoprotein (LDL),very low density lipoprotein (VLDL),GOT,lactate dehydrogenase(LDH),creatine phosphokinase (CPK),MB isoforms of creatine phosphokinase (CPK-MB),? hydroxybutyrate dehydrogenase (?-HBDH),troponin I(TnI),cerebral CT or MRI and carotid ultrasonography.The patients were divided into two groups,ECI and completed cerebral infarction (CCI),according whether neurons function scale deteriorated.When cases of both groups exceeded 50,we took statistic test by SPSS10.0 statistic software.Results 8 of the above 46 markers had significant defference between the two groups,including CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH and DBP.ECI was more common in patients who had lower DBP or higher CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH when they were admitted.Conclusion The increase of CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH or decrease of DBP when patients are admitted can be predictive markers of ECI.

To investigate the short term anti HBV efficacy of foscarnet sodium, sixty seven patients with various types of chronic hepatitis B were randomly divided into two groups. The experimental group (47 cases) was assigned to receive foscarnet sodium 3 0g by intravenous infusion twice daily in addition to general liver protective medicine for 15 days. The control group (20 cases) was treated with regular liver protective medicine only. The quantity of HBV DNA was measured with equivalent competitive PCR combining with DNA hybridization quantitative detection technique before and after treatment (once a week). The HBV markers and liver functions were also tested before and after treatment. In antiviral therapy group, the patients with different types of hepatitis B had their liver functions improved. HBV DNA in 13 patients became negative by PCR. Two of HBeAg positive patients became sero converted. Foscarnet sodium can inhibit HBV efficiently and quickly. The replication of HBV DNA can be greatly suppressed in the first week but without significant change in the second week in some cases. Foscarnet can be one of the drugs of choice in a combined therapy or as the initial drug in a sequential therapeutic regime.
