Objective The study was conducted to investigate the acute phase of convulsion related problem on the clinical manifestations,imaging and electroencephalograph (EEG) examination of purulent meningitis.Methods Cluster sampling method was employed to select children in our hospital,a total of 301 cases with purulent meningitis was analyzed retrospectively.Among them,62 cases had convulsion.The incidence of convulsion in the acute phase of the purulent meningitis,risk factors,and prognosis were analyzed.Results The convulsion incidence rate of acute purulent meningitis was 20.60％.The partial seizure was eight cases (12.90％).The secondarily generalized seizure following partial seizure was 15 cases (24.19％).The generalized seizure was 32 cases (51.61％).The convulsive status was 7 cases (11.29％).The EEG abnormality was significantly different between the convulsion group and the no convulsion group (P ＜ 0.05).The incidence of brain organic damage was significantly different between two groups (P ＜0.05).The multivariate unconditional logistic regression analysis showed,cause of disease,first symptom,disturbance of consciousness,obvious signs,and cerebrospinal fluid culture with convulsion were the relevant factors (P ＜ 0.01).Conclusions The most common seizure of purulent meningitis was the generalized seizure.Brain organic damage easily resulted in convulsion of purulent meningitis.The days of hospitalization,cause of disease,first symptom,disturbance of consciousness,obvious signs,and cerebrospinal fluid culture with convulsion were the positively relevant factors.Those positively relevant factors in combination of the clinical manifestations,imaging,and EEG examination in children would play an important role in diagnosis,treatment,and prognosis evaluation of convulsion derived from purulent meningitis.Moreover,convulsion affects the disease recovery in children with purulent meningitis.

Using colon adenocarcinoma cell line HT-29 as testing material, adhesion test was carried out for 24 strains of Bifidobacteria isolated from dejecta of longevous people aged one hundred years. The results showed that all strains could adhere to colon adenocarcinoma cells HT-29, among which the strains of TTF, Z2, TZ5 and (J-1) showed higher adhesive capability. Thus these four strains of Bifidobacteria were further tested for their endurance to stomach acid and bile acid. The production of vitamin B by these bacterial were also tested. All these tests indicated that the strain of TTF has high ability to produce Vitamin B_(1), B_(2), B_(6), B_(12), The survival rate after the treatment under pH 3.0 for 120 min was 93.11%, at the same time, the strain TTF can survive after being treated with 2% bile acid for 24h.

To study the stimulation effect to the growth of Bifidobac te rium sp. A04, 4 kinds of oligosaccharide, 8 kinds of Chinese traditional medi cine and 4 kinds of food raw materials were used. The results indicates that so ya bean oligosaccharide is the most effective (P

Objective To study the clinical features of the variants of benign childhood epilepsy with central temporal spikes (BECT).Methods The clinical data of 12 hospitalized pediatric patients with BECT from Jan 2007 to Jan 2014 were retrospectively reviewed. Results There were 7 boys and 5 girls in 12 patients. The age of onset was from 3 to 9 years old. Two cases were dizygotic twins. The atypical symptoms included atypical absence of 10 cases, negative myoclonic seizure of 8 cases, speech expression disorders and oral-pharynx apraxia of 4 cases. The electroencephalography (EEG) of all 12 patients showed abundance of spike and waves (SW) in rolandic areas during wake-up and sleep. The SW index was 50%-85% during slow sleep in all patients.Conclusions The variants of BECT are often associated with EEG deterioration. Understanding the clinical featuress and EEG characteristics can help the diagnosis of BECT variants.

Objective To analyze the potential etiologies and risk factors of childhood stroke. Methods This study retrospectively reviewed the clinical data of 159 children who were admitted from Jan.2006 to Jan.2014. Results The 159 children were composed of 100 boys and 59 girls , with median onset age of 1.8 years (ranged from 1 day to 12 years old) and median peak age of 0.9 years (ranged from 3 months to 2.8 years old). Their initial symptoms included limb hemiplegia,language dififculties and convulsion. The common causes included infections found in 46 cases (central nervous system infection in 32 cases, respiratory and gastrointestinal tract infection in 14 case), head injury in 42 cases, vitamin K deifciency in 29 cases, Moyamoya disease in 8 cases, heart diseases in 11 cases, spontaneous hemorrhage in 11 cases and 12 cases of unknown reason. Infectious diseases were the most common cause of children acute ischemic stroke in toddler period;and vitamin K1 deifciency were the most common cause of children hemorrhage stroke in infancy. The most common region of infarction is basal ganglia and middle cerebral artery in neuronal imaging. The median age at the time of diagnosis was 1.4 days. The median time of inhospital was 28 days. The median apex time was 4.3 days. Conclusions Among 159 cases, acute ischemic stroke is much more common than hemorrhagic stroke in children stroke, and the major risk factors are infections and head injury;Vitamin K1 deifciency is a major risk factor in infants with hemorrhagic stroke.

Orthogonal combination design was adopted in examining the Spirulina platensis (S. platensis) yield and the influence of four factors (Se content, Se-adding method, S content and NaHCO3 content) on algae growth. The results showed that Se content, Se-adding method and NaHCO3 content were key factors in cultivation conditions of Se-enriched S. platensis with the optimal combination being Se at 300 mg/L, Se-adding amount equally divided into three times and NaHCO3 at 16.8 g/L. Algae yield had a remarkable correlation with OD560 and floating rate by linear regression analysis. There was a corresponding relationship between effects of the four factors on algae yield and on OD560, floating rate too. In conclusion, OD560 and floating rate could be served as yield-forming factors.

Objective To investigate the angiographic manifestation of the proper esophageal artery (PEA),the hish risk factom for the presence of the anomalous PEA in hemoptysis and to evaluate the safety of transcatheter aaefial embolization(TAE) of the PEA using gelatin sponge(GS).Methods Selective esophageal arteriography WSS performed in forty-three patients with hemoptysis,including 15 cases of pulmonary tuberculosis,18 cases of bmnchiectasis,7 cases of posttuberculous bronchiectasis and three cases of lung cancer. One case experienced failure of bronchial arterial embolization. The angiographic manifestation of the PEAs Was studied.The complications of the procedure and clinical results were observed in the patients who underwent TAE using GS.Results Thirty-nine PEAs were catheterized selectively in 37 patients(86.0%).Eighteen anomalous PEAs(46.2%)were catheterized selectively in 17 patients (45.9%).The anomalous PEAs showed tortuosity,dilatation,hyperplasia,shunting with pulmonary artery and anastomosis with the bronchial artery.All lesions involved basal segment of inferior pulmonary lobar. Bronchiectasis Was the most frequent disease for PEA abnormality. No complications occurred and satisfactory curative effect Was achieved with TAE of the anomalous PEAs.Conclusions It is necessary to perform selective proper esophageal arteriography when the lesion involves basal segment of inferior pulmonary lobar in hemoptysis.Supplemental TAE of the anomalous PEA using GS is safe and valuable in the management of hemoptysis.
