Objective To explore the imaging characteristics of neurologic complications associated with the enterovirus 71 ( EV71 ) epidemic by analyzing 25 cases and reviewing the literature. Methods Twenty-five cases of hand-foot-mouth disease with neurologic complications during the recent EV71 outbreaks of Hainan province were studied for the clinical features and imaging findings, and literature were reviewed.Results In 5 cases, acute flaccid paralysis associated with EV71-infected hand-foot-mouth disease was related to the linear high signal in the spinal cord on sagittal images. Two cases showed symmetrical, welldefined hyperintense lesions in the spinal cord on T2WI transverse. Strong enhancement of the ventral horns and root was seen on the contrast-enhanced axial T1WI. In brainstem encephalitis, all lesions presented with significant hyperintensity on T2WI and hypointense on T1WI in the posterior portions of the medulla oblongata, midbrain, and pons. The manifestations of aseptic meningitis (AM) on MRI have no characteristics, but subdural effusion, meningeal enhancement and hydrocephalus can be the indirect signs of AM. Conclusions MRI is an effective method to investigate neurologic complications associated with the EV71 epidemic. Posterior portions of the medulla oblongata and pons, bilateral ventral horns of spinal involvement are characteristic findings of enteroviral encephalomyelitis.

To examine the effects of ischemia and anoxia on cell activation and cell cycle of astrocytes in vitro, the cell cycles and the proliferation of astrocytes in different time points after ischemia and anoxia were studied by flow cytometry and BrdU labeling and the expression of GFAP and cyclin D1 was detected by the fluorescence immunochemistry. After ischemia and anoxia in vitro, the astrocytes in S phase were significantly increased as compared with those in the normal group and the proliferating ability of the astrocytes was highest 6 h after the treatment as revealed by BrdU pulse labeling, but the astrocytes in S phase and proliferating ability were decreased after 6 h. At the early stages of ischemia and anoxia, the positive staining intensity of GFAP was increased, peaked at 6th h, while 12 h after the ischemia and anoxia, the positive staining intensity of GFAP became weak, and the expression of cyclin D1 was gradually increased after the ischemic and anoxic damage. It is concluded that astrocytes are activated to proliferate and enter new cycle events by ischemia and anoxia, and cyclin D1 is implicated in the proliferation and repair of astrocytes. The cell cycle events are closely associated with the proliferation and activation of astrocytes.

Objective To study the association of the expression of bone morphogenetic protein (BMP) antagonist gremlin and vascular calcification in radial arteries of patients with stage 5 of chronic kidney disease (CKD).Methods Radial arteries of 40 patients with stage 5 of CKD were collected as specimens of the study group,which were trimmed off during arterial venous fistula operations.Splenic trabecular arteries were collected as specimens of the control group,which were removed from 38 patients with simple traumatic splenic rupture.All the arteries were examined histologically for calcification with yon Kossa stain.Expressions of gremlin and BMP-2,-7were detected by immunohistochemistry and their serum concentrations were detected by ELISA.Images of histological sections were semi-quantitatively analyzed by Image-Pro Plus 6.0.SPSS 19.0software was used to perform statistical analysis.Results Significantly positive von Kossa stain was found in radial arteries from 12 of 40 patients (30％) in study group,which located in the layer of medial smooth muscle cells.However,there was no obvious positive stain in control group.Additionally,in study group,significant expressions of gremlin and BMP-2 were detected in those radial arteries of positive yon Kossa stain,which also located in the layer of medial smooth muscle cells.Positive correlations were found among gremlin expression level,BMP-2 expression level and yon Kossa stain intensity.However,the BMP-7 expression intensity in arteries of study group was much weaker as compared to control group.Conclusions Both gremlin and BMP-2 may be involved in the process that the smooth muscle cells of radial arteries in patients with stage 5 of CKD phenotypically transform into osteoblast-like cells.However,BMP-7 possibly prevents this process.

ObjectiveTo assess the clinical efficacy and safety of donepezil in treating the mild to moderate cognitive impairment of vascular dementia.Methods60 patients with vascular dementia were randomly divided into therapy group (donepezil 5 mg/d for 4 weeks, and then increased to 10 mg/d) and control group (piracetan 800 mg,3/d). All patients were assessed with Mini Mental State Examination (MMSE), Wechsler Adult Intelligence Revised in China (WAIS-RC), Activities of daily living (ADL), and Clinical Global Impression (CGI), before and 12 weeks after treatment. ResultsMMSE scores improved significantly in both groups after the treatment. The therapy group produced significantly better scores than the control groups on the MMSE(P<0.05). WAIS-RC scores improved significantly in the therapy groups(P<0.01), but there was no significant difference for control groups(P>0.05), before and after treatment. Severity Improvement(SI) score of ADL and CGI in the both groups decreased. The total efficiencies of donepezil and piracetan groups were 86% and 56% respectively. There was no significant difference in adverse effects between two groups. ConclusionDonepezil can improve the cognitive function of patients with vascular dementia, which seems better than that of piracetan, and it is fairly safe for vascular dementia patients to take donepezil 10 mg a day.

Objective To investigate the alterations of dopamine,norepinephrine,cortisol,C-reactive protein (CRP),heart rate (HR),respiratory rate (RR) and mean artery pressure (MAP) before and after the laser photoeoagulation for retinopathy of prematurity (ROP) with topical anesthesia and to provide the guideline for improving its routine management and interventions.Methods Thirty children with ROP who received ROP laser photocoagulation in Guang zhou Women and Children's Medical Center from May to Dec.2012 were selected.The blood of the 30 cases of infants were collected at 4 time points:before laser therapy,the end of laser therapy,1 hour and 24 hours after laser therapy.The concentrations of dopamine,norepinephrine,cortisol and CRP in plasma were measured at each time point with radio immunoassay,and the values of HR,RR and MAP of infants were recorded as well.Results The levels of dopamine,norepinephrine and cortisol at the end and 1 hour after therapy were higher than those in the quiet state before therapy,and the differences were statistically significant (t =6.39,2.55 ; t =7.74,2.91 ; t =8.87,2.15 ; all P ＜ 0.05) ; the levels of CRP at the end of therapy,1 hour and 24 hours after therapy had no statistical difference in comparison with those in quiet state before therapy (t =0.06,0.89,1.16; all P ＞ 0.05) ; the levels of HR and RR at the end of therapy,1 hour and 24 hours after therapy had statistical difference in comparison with those in the quiet state before therapy (t =4.33,3.84,3.38 ; t =6.81,4.42,2.96 ; all P ＜ 0.05).The level of MAP at the end of therapy had statisti cal difference in comparison with that in the quiet state before therapy (t =6.10,P ＜ 0.001).Conclusions Infantswho experieneed ROP laser photocoagulation had stress response.Clinicians should pay more attention to monitoring HR and RR of preterm infants receiving retinal laser photocoagulation under topical anesthesia and take active intrvventions in order to relieve the stress response.

Objective To study the telomerase activity,the keratinocyte apoptosis in condyloma ac-cuminatum(CA)and the correlation between them.Methods CA specimens from30patients were stud-ied,and compared with normal tissue and tumor cell lines.Telomerase activity was detected with telomeric repeat amplification polymerase chain reaction(TRAP)-ELISA.Terminal deoxynucleotidyl transferase(TdT)-mediated biotin dUTP nick end-labeling(TUNEL)was used to evaluate apoptotic cells.Results Increased telomerase activity was detected in27(90%)patients with CA,with A 450 ranging between0.50and2.76(mean1.3022).Apoptotic keratinocytes were found in24out of30CA cases(80%).A statistically signifi-cant inverse correlation was found between telomerase activity and apoptotic index(r =-0.52,P=0.004).Conclusion Keratinocyte telomerase is activated in condyloma acuminata,which is correlated with the downregulation of apoptosis,thus they might be involved in the pathogenesis of CA.
