Objective To investigate the protective effect and therapeutic window of DGMI on ischemic stroke in rats,and to explore the related mechanism.Method The rats were subjected to middle cerebral artery occlusion (MCAO) for 90 min followed by 72 h of reperfusion.DGMI (i.p.,1.25,2.5,5.0,and 10.0 mg/kg,Bid) was administered at 1 h after the onset of ischemia.Neurological score was evaluated after 24 and 72 h of reperfusion rcspectively.In fact volume,cerebral water content,oxidative stress markers,and IL-1β were evaluated after 72 h of reperfusion.The rats were treated with DGMI 5.0 mg/kg 0.5 h before reperfusion or 1 h,2 h,3 h,and 6 h after reperfusion to determined therapeutic window.Result Treatment with DGMI (2.5,5.0 mg/kg) significantly ameliorated neurological deficit,infarct volume and cerebral water content after cerebral ischemia reperfusion.DGMI also reduced the content of malonaldehyde (MDA),IL-1β,down-regulated the activities of creatine kinase (CK),lacticdehydrogenase (LDH),and up-regulated the activities of superoxide dISmutase (SOD).Treatment with DGMI 5.0 mg/kg exhibited protective effects when administered at all time points except for 6 h after reperfusion.Conclusion DGMI plays a certain protective role in ischemic stroke of rats,and the effect may be related to the improvement on the antioxidant capacity of brain tissue and the inhibition of overproduction of inflammatory cytokine.Moreover,the therapeutic window of DGMI isless than 6 h after reperfusion.

To determine HIV prevalence among blood donors in Zhejiang Province from 1993 to 2004 years, almost 6,600, 000 blood donors information were collected and analyzed. Every sample was screened for markers of HIV-1 and HIV-2 by using commercially available ELISA kits twice, and Western blot for confirmation if positive or suspicious result appeared. The results indicated that during the study period, prevalence rate of HIV infection was 0.85/1000 donors (0.085%), with the rising tendency from 1:600000 in 1995 to 1:37500 in 2004. The prevalence of HIV infection in Zhejiang donors was significantly lower than that in donors of other provinces, prevalence of HIV infection in male was higher than that in female. In recent years, the prevalence of HIV in blood donors was obviously increased, but the difference among various populations began to reduce. It is concluded that in a low HIV prevalence area like Zhejiang province where no obvious AIDS occurred, risk for the expansion of the HIV epidemic was on the increase. Screening procedure used in transfusion services nowaday is reliable, but a comprehensive approach is required to make the blood more safe.

Objective To investigate the diagnostic value of prenatal ultrasonography in the fetal hemivertebra. Methods The ultrasonographic findings of three fetuses with hemivertebra diagnosed in our hospital were reviewed and compared with those of postnatal ultrasonography,other image modalities,and autopsy. Results In all fetuses,a distortion of the spine was observed where only one half of the vertebra could be identified. The parents opted for termination of the pregnancy in one case and the deformity was confirmed by autopsy. The other two fetuses were delivered and in one fetus the diagnosis was confirmed by radiological assessment. Conclusions Hemivertebra can be diagnosed accurately by second-trimester ultrasonography. The prognosis is mostly favorable when no other anomalies are associated. Meticulous examination may disclose the lesion and help decide the fate of pregnancy.

Objective To determine the diagnostic value of two and three dimensional ultrasound in detecting fetal hand malformations. Methods In the retrospectively analysis,the severe fetal hand malformations detected by prenatal ultrasound during the recent three years in our hospital were classified according to the prenatal sonographic characteristics,family history,karyotype analysis and autopsy results,etc.Results Fourteen fetuses with hand-anomaly were detected during the 16-28th week of gestation,both hands were affected in 10 cases,with the same morphology bilaterally in 8 cases.Thirteen cases had other abnormal sonographic findings.They were detected and classified into three categories,Wrist deformity (9 cases),three fetuses were associated with total absence of radius and radial clubhand,and six fetuses had palmar deviated hands,with various etiologies including familial hereditary arthrogryposis multiplex congenita,distal type 1 (AMCD1),amniotic band syndrome,body stalk anomaly,trisomy18 and micromelia.Hand (figer) hypoplasia or aphasia (3 cases),one hand was absent in one fetus without associated anomaly,absence of five fingers with ipsilateral multicystic dysplastic kidney in the second fetus,and the third fetus had split hand/foot malformation (SHFM).Overlapping fingers (4 cases),three of them were trisomy18,and two fetuses had both wrist deformity and overlapping fingers.Conclusions Prenatal two and three dimensional ultrasound play an important role in detecting and diagnosing severe type of fetal hand malformations.
