Correlation of ABO groups to hypertensive intracerebral hemorrhage / 南方医科大学学报

<p><b>OBJECTIVE</b>To study the relationship between ABO blood groups and hypertensive intracerebral hemorrhage (HICH).</p><p><b>METHODS</b>The clinical data of 425 patients with HICH admitted to Nanfang Hospital were collected to analyze the relationship between the ABO blood groups and the occurrence of HICH, with normal Han Chinese subjects serving as the controls.</p><p><b>RESULTS</b>Compared to the officially documented distribution of ABO groups in Chinese population (O 34.11%, B 28.98%, A 28.29%, AB 8.69%) and in Guangzhou residents (O 46.00%, B 25.00%, A 23.00%, AB 6.00%), a significant difference was noted in the blood group distribution in this cohort (O 45.10%, A 26.00%, B 24.00%, AB 4.90%). O blood type individuals with HICH showed a higher morbidity than others. Th ABO blood type distribution in this cohort showed no significant difference from that in the control group (P>0.05), but differed significantly from the Chinese norm (P<0.05).</p><p><b>CONCLUSION</b>The ABO blood group is a factor contributing to the occurrence of HICH. O blood type is related to cerebral hemorrhage, and may serve as a risk factor for HICH.</p>

Treatment of erectile dysfunction after radical retropubic prostatectomy with PDE5 inhibitor / 中华男科学杂志

The rate of erectile dysfunction after radical retropubic prostatectomy is from 10% to 100%. The prevalence of erectile dysfunction after nerve-sparing radical prostatectomy is more than one third. In the patients who had undergone bilateral NS, 72% responded to sildenafil, 71.7% and 59.7% responded to 20 mg and 10 mg of vardenafil respectively. For all randomized patients who received tadalafil, the mean percentage of successful penetration attempts was 54% and the mean percentage of successful intercourse attempts was 41%. For the subgroup with evidence of postoperative tumescence these values were 69% and 52%, respectively. No head-to-head trials have been performed with sildenafil, vardenafil and tadalafil in treatment of erectile dysfunction after radical prostatectomy.

Influence of the early intervention on mental and psychological development in infants with hypoxic-ischemic encephalopathy / 中国组织工程研究

BACKGROUND: Perinatal hypoxic-ischemic encephalopathy(HIE) is the primary cause of neonatal brain injury, which retards the mental development in affected infants.OBJECTIVE: To investigate the influence of early intervention on mental and psychological development in infants with HIE, study the time-effect relation of the early intervention, and to find an optimal time for intervention.DESIGN: A time series of following-up and a non-randomized concurrent controlled investigation.SETTING: Xiangya Hospital and Xiangya School of Medicine Affiliated to Central South University.PARTICIPANTS: From February 1999 to May 2001, in the Pediatric Department of Xiangya Hospital Affiliated to the Central South University, the inpatient and outpatient infants with HIE were selected. There were 32 inpatients in the intervention group, 10 with moderate HIE and 22 with severe HIE. There were 36 outpatients in the control group, 10 with moderate HIE and 26 with severe HIE. Comparison was performed between these two groups.METHODS: BRS and the Infant and Child Mental Development Scales,made by The Institute of Psychology of The Chinese Academy of Science and The China National Children' s Center(CNCC), were adopted in the assessment between the two groups.MAIN OUTCOME MEASURES: Mental Development Index(MDI) and Psychomotor Development Index(PDI) scores of the two groups were compared.were significantly higher in the intervention group(90.50 ± 11.12/90. 34±12.49,94.06±14.96/92.03±13.07,90.78±7.46/91.38 ± 13.87)than those in the control group(62.28±7.44/62.67±6.06, 59.11following-up results showed that one patient in the intervention group had a MDI score at the critical threshold value, and two patients had PDI scores at the critical threshold value. For all the other patients in this group, the MDI/PDI scores of them were above the moderate range. In contrast, all the 36 infants in control group had developed mental deficiencies at that time.CONCLUSION: A quantifiable effect of the intervention can be observed in patients at 3 months of life. This indicates that an early intervention is essential for improving the mental development in infants with HIE.
