Objective To explore clinical characteristics of severe pre-eclampsia and eclampsia complicated with reversible posterior leukoencephalopathy syndrome(RPLS).Methods Clinical data of 31 cases of severe pre-eclampsia and eclampsia complicated with RPLS were studied retrospectively.ResulIs These 31 cases with RPLS accounted for 48% of those with eclampsia,.and all presented with hypertension,headache and disturbalice of vision,24 cases with seizure episodes,19 cases with nausea and vomiting and 13 with continuous dysphoria after seizure.Neuroradiologic findings showed edema predominantly in the bilateral posterior cerebral white matter,especially in occipital-parietal lobe,with low density lesions in CT and long T1 and T2 signals in brain MRI. Conclusions Severe pre-eclampsia and eclampsia tended to complicate with RPLS,presenting severe hypertension,headache,disturbance of vision and recurrent seizure as major clinical manifestations.

Estimation of postmortem interval(PMI) by ocular tissues has been a new top subject in the forensic research and practice ifelds. A lot of research results showed that the changes of cornea, retina, vitreous humor and aqueous humor and so on exist a high linear correlation with PMI, which can be used to estimate PMI. This paper reviewed recent progress of study on them.

Objective To investigate the effects of azithromycin on hyperoxia induced lung injury in neonatal rats.Methods Ninety 2-day-old neonatal rats were randomly divided into 3 groups (30 cases in each group):air control group,hyperoxia model group,azithromycin treated group.The rats in air control group were exposed to indoor air,and the rats in hyperoxia model group and azithromycin group were exposed to 900 mL?L-1 O2 for 14 days.From 2-days-after birth,rats in treated group received intraperitoneal injection of azithromycin (200 mg?kg-1)per day,rats in air control group and hyperoxia model group received intraperitoneal injection of normal saline.Ten rats in each group were executed and their lung tissues were taken out and were observed under a optical microscope on the 3rd,7th,14th days from the start.The expression of interferon gamma(IFN-?),connective tissue growth factor(CTGF) and matrix metalloproteinase-9 (MMP-9) in the lung tissues were detected by immunohistochemistry.Results There was no expression of IFN-? positive cells in air control group,but the expressional intensity level was gradually enhanced as the time of inhaling hyperoxia prolonged in hyperoxia model group,it reached the peak on the 7th day,and then obviously declined on the 14th day,but still higher than that of air control group.The expressional intensity level of IFN-? in azithromycin treated group was lower than that of hyperoxia model group in each time segment,there were significant differences among them(Pa
