Clinical, radiological and pathological presentations in two children with epidermal nevus syndrome were analyzed and relevant literature was reviewed.Two patients both had typical epidermal nevus and abnormal cerebral radiography, which was associated with mental retardation, epilepsy, language and movement retardation.One case was complicated with an ocular tumor.Pathological investigations of the epidermal nevus revealed papilliform proliferation in squamous epidermis.The disorder may have a systemic involvement besides cutaneous lesions, with a predilection for the central nervous system.Early diagnosis and therapy may help to improve patients life quality.

To investigate the role of AQP9 in brain edema, the expression of AQP9 in an infectious rat brain edema model induced by the injection of lipopolysaccharide (LPS) was examined. Immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR) analysis demonstrated that the expressions of AQP9 mRNA and protein at all observed intervals were significantly increased in LPS-treated animals in comparison with the control animals. Time-course analysis showed that the first signs of blood-brain barrier disruption and the increase of brain water content in LPS-treated animals were evident 6 h after LPS injection, with maximum value appearing at 12 h, which coincided with the expression profiles of AQP9 mRNA and protein in LPS-treated animals. The further correlation analysis revealed strong positive correlations among the brain water content, the disruption of the blood-brain barrier and the enhanced expressions of AQP9 mRNA and protein in LPS-treated animals. These results suggested that the regulation of AQP9 expression may play important roles in water movement and in brain metabolic homeostasis associated with the pathophysiology of brain edema induced by LPS injection.

Epilepsy is one of the most common chronic diseases of the central nervous system,many epilepsy patients need lifelong medication.Epidemiological studies have shown that 3‰-5‰ neonates born by women suffering from epilepsy.Treatment become more challenging because not only the patients themselves but also the breastfed in fants should be taken into consideration.This paper reviewed how to choose lactation antiepileptic drug.In short,choosing drugs which transport less to milk and have less side effects to infants,using the lowest effective dose and avoiding combination if possible can ensure the safety of breastfeeding.

Objective To analyze the clinical features,treatment and prognosis of children with post-stroke epilepsy.Methods Sixty-nine children with epilepsy after cerebral stroke who were admitted to Guangdong General Hospital from Jan.2009 to Mar.2013 were retrospectively reviewed,including etiology,clinical features,laboratory examinations,treatment and prognosis.Results Among 260 stroke patients,69 of them (26.5 ％) developed epilepsy,but there was no significant difference between boys and girls(x2 =0.725,P =0.394).The incidence of post-stroke epilepsy differed significantly among different types (x2 =12.000,P =0.02),highest in the children with subarachnoid hemorrhage(47.8％,11/23 cases),followed by those with cerebral hemorrhage (34.6％,27/78 cases),and lastly,those with cerebral ischemia (19.5％,31/159 cases).Among them,53 patients developed seizures in the early stage (76.8％,53/69 cases),others in the late stage(23.2％,16/69 cases),early-onset epilepsy was more common in hemorrhagic stroke and late-onset epilepsy was more common in ischemic stroke,which differed significantly(x2 ＝ 4.778,P =0.029).The electroencephalogram background generally showed slow-wave in the early-onset epilepsy.The composition of seizure types differed significantly among different types of stroke (x2 =8.461,P =0.015).Forty-five of 58 patients (77.6％) suffered from cortical lesions and 13 of 58 patients (22.4％) suffered from subcortical lesions.Those children with post-stroke epilepsy who regularly use of antiepileptic drugs were followed up for 6 months to 4 years,81.2％ (56/69 cases)of clinical seizures were controlled.Conclusions The incidence of epilepsy after stroke is higher in children than in adults,cerebral stroke seizure occurs more commonly in cases with hemorrhagic stroke,especially with subarachnoid hemorrhage.Conventional antiepileptic treatment is effective.

Objective To evaluate the effect of traditional Chinese medicine sputum discharge liquid on preventing ventilator-associated pneumonia(VAP).Methods A randomized double-blind,placebo-controlled study was con-ducted,according to the inclusion and exclusion criteria,patients with respiratory failure and mechanical ventilation in the intensive care unit (ICU)of a hospital in 2011 -2014 were selected and divided into treatment group and con-trol group.Treatment group received sputum discharge liquid in addition to conventional treatment,control group adopted simulation agent based on conventional treatment.The incidence,treatment effectiveness,occurrence time, and prognosis of VAP between two groups of patients were compared.Results A total of 139 patients were monitored,70 cases in treatment group and 69 in control group.The incidence of VAP in treatment group and con-trol group were 37.14% (n =26)and 57.97%(n =40)respectively;the average onset time of VAP in treatment group and control group were (76±3.2)hours and (45±8.9)hours after admission to ICU respectively;treatment effectiveness rates in treatment and control group were 88.46% and 55.00% respectively;the incidence,occurrence time,and treatment effectiveness rates of VAP between two groups of patients were both significantly different (all P <0.05).There were no significant difference in blood routine,liver and kidney function,urine routine,stool rou-tine,and electrocardiogram results between two groups of patients (all P >0.05 ).Conclusion Intervention in patients with mechanical ventilation by sputum discharge liquid can reduce the incidence of VAP,and has a positive effect on the prognosis of disease and pulmonary infection in patients.

Objective To study the effect of glycyrrhizin(GL) on the gene expression of high mobility group protein 1 (HMGB1) in hippocampus and serum.To evaluate the effect on the expression of neuron-specific nuclear-binding protein (Neu-N) in the hippocampus CA1,CA3 regions in the chronic stage of an immature rat epilepsy model.Methods Fifty-two 21 day-old SD rats were randomly divided into control group,model group Ⅰ and model group Ⅱ according to the random table method.Model group Ⅰ was induced epilepsy by kainic acid (KA),and the model group Ⅱ was pretreated with GL by intraperitoneal injection at 30 min before KA injection.According to the different observation time points,each group was divided into 4 subgroups:3 h,12 h,24 h and 7 d.Model group Ⅱ was divided into 3 subgroups:10 mg/kg,50 mg/kg,100 mg/kg,according to the different doses of GL.There were 3 animals in each subgroup.Score was performed according to the Racine score,and quantitative real-time polymerase chain reaction and Western blot were applied to detect the mRNA and protein expression of HMGB1 in the acute phase.Enzyme-linked immunosorbent assay(ELISA) was applied to measure the expression of HMGB1 in blood;immunohistochemical was applied to measure the expression of Neu-N in hippocampus in the chronic phase(7 d).Results Compared with model group Ⅰ,seizure onset time was obviously prolonged in model group Ⅱ [(24.08 ± 1.98) min vs.(33.39 ± 2.66) min],and the difference was statistically significant (t =9.231,P ＜0.05);Comparing KA model group Ⅰ with control group,the gene expression of HMGB1 significantly increased,and reached a peak at the time of 12 h (H =10.532,P ＜ 0.05),but the protein expression of HMGB1 was changed obviously and there was no significant difference (H =5.227,P ＞0.05).The expression of HMGB1 in the serum also significantly increased,especially at 12 h (H =6.897,P ＜0.05).At the time of 12 h after KA injection,the gene expression of HMGB1 in the hippocampus was significantly decreased in model group Ⅱ compared with model group Ⅰ (H =10.721,P ＜0.05) (especially in the 100 mg/kg model group).Also,the expression of HMGB1 in the scrum was obviously decreased (H =6.967,P ＜ 0.05) (especially in the 100 mg/kg model group).At the time of 7 d after KA injection,hippocampal neuron loss in model group.Ⅰ was significantly reduced compared with control group (P ＜ 0.05),and hippocampal neuron loss in model group Ⅱ was evidently decreased compared with model group Ⅰ (P ＜ 0.05),(especially in the 100 mg/kg model group in CA1,50 mg/kg model group in CA3).Conclusions In the immature rat temporal lobe epilepsy model,GL may have neuroprotective by inhibiting the synthesis and release of HMGB1,inhibiting inflammation further to restrain the loss of neurons in the chronic phase.

The clinical data of a child with anti-(α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid, AMPA2) receptor antibody encephalitis after herpes simplex encephalitis was retrospectively analyzed.The child was a 9-year-old female developing abnormal mental behavior after fever.The auxiliary examination of the first hospital displayed, cerebrospinal fluid: sugar qualitative (+ ), white blood cell count 32×10 6/L, albumin measurement (immune turbidity method) 317.00 mg/L, immunoglobulin IgG 45.80 mg/L.Herpes simplex virus (+ ). Skull magnetic resonance imaging showed: abnormal signal at the top of the frontal frontotemporal, considering intracranial infection.Video electroencephalogram: the background is diffuse slow wave, a small amount of multifocal spikes, sharp waves, spine slow wave release, left frontal, and temporal sacral protrusions.One partial seizure may be detected during the awake period.The diagnosis was " herpes simplex virus encephalitis" , and the body temperature of the child returned to normal after anti-infection and hormone therapy.However, there were still cognitive impairments, irritability, and no language communication.After 2 years, there was no abnormality in routine biochemical and viral cerebrospinal fluid examination.Serum and cerebrospinal fluid autoimmune encephalitis-related antibody spectrum: anti-NMDA, AMPA1/2, GABAB receptor antibody and anti-CASPR2, LGI1 antibodies were negative in serum.The anti-AMPA2 receptor antibody in the cerebrospinal fluid was weakly positive, and the final diagnosis was anti-AMPA2 receptor antibody encephalitis.After the application of hormones, the children′s cognition improved, mood was more stable than before, and language communication improved as well.Anti-AMPA2 receptor antibody encephalitis can be observed in children, and may be related to immune response after viral infection.For patients of viral encephalitis with poor treatment or disease relapse and progression, the possibility of autoimmune encephalitis should be considered.

Objective To evaluate the growth inhibition of human gastric carcinoma cell lines SGC 7901 in vitro and the expression of bcl-2, bcl 2l12 and bax with docosahexaenoic acid (DHA) and 5-fluorouracil (5-FU). Methods The effect of DHA and 5-FU was measured by trypan blue, and the interaction between two agents was judged by combination index (CI). Cells were observed by inverted microscope. Flow cytometry was used for analysis of apoptosis by PI staining and Annexin-V/PI. RT-PCR was used to analyze the levels of bcl-2, bcl 2l12 and bax mRNA. Results DHA significantly inhibited the growth of SGC 7901 cells in a dose- and time-dependent way ( P < 0. 05 ), the IC50 of 24 h and 48 h was 67. 81 μg/ml and 45.76 μg/ml, and a strong synergism was found in the combination of DHA and 5-FU (CI < 1 ,P <0. 01 ). Treated by DHA and 5-FU for 48 h, cells became sparse under inverted microscope. DHA or 5-FU was able to induce apoptosis and the effect became even more significant by the combination of DHA and 5-FU. Cells were holted in phase of G01/G1 and S. RT-PCR showed that DHA or 5-FU down-regulated the expression of bcl-2 and bcl 2l12 mRNA, while bax mRNA expression was not downregnlated. Conclusions DHA could inhibit the growth of gastric carcinoma cells, DHA and 5-FU had synergetic effect in the inhibition of the cells growth and blockage of the cell cycles possibly by down-regulating the expression of bcl-2 and bcl 2l12.
