Since the oral rehydration salts solution(ORS) has been used to treat acute diarrhea of children, there are different kinds of ORS in order to satisfy the need of clinical work. They are the initial WHO-ORS, other substances-supplemented ORS and the reduced osmolarity ORS, each of which has their own efficiency and advantage.

ObjectiveTo compare the CT features of retroperitoneal ganglioneuroblastoma (GNB) and neuroblastoma (NB) in children,and summarize the differentiations between them.Methods From November 2007 to November 2011,19 patients with GNB and 21 patients with NB proven pathologically were enrolled in the study.The CT data of GNB and NB were analyzed retrospectively.These tumor parameters in CT included lesion location,size,shape,margin,calcification,across central line,style of contrast enhancement,degree of contrast enhancement,presence of small vessels in or around the tumor arranged in clumps or in line,tumor embolus,adjacent organs invasion or metastasis,lymph node metastasis,and relationship between tumor and surrounding great vessels.These parameters of both groups were compared by x2 and t test.ResultsIn GNB group,11 patients were located in adrenal gland and 8 patients in the retroperitoneal sympathetic chain; however,in NB group,18 patients were located in adrenal gland and 3 patients in the retroperitoneal sympathetic chain. The difference were statistical significances in the incidence rate of regular morphology,clear border,vessel encased by tumor,vessels displaced,presence of small vessels in /around the tumor arranged in clumps or in line,adjacent organs invasion or viscera metastasis,lymph node metastasis between NB (6/21,7/21,14/21,7/21,11/21,10/21,and 11/21,respectively) and GNB ( 12/19,13/19,6/19,13/19,4/19,3/19 and 4/19,respectively) ( P ＜ 0.05 ).However,there was no statistical significance in size,calcification,across central line,contrast enhancement type,contrast enhancement degree between them ( P ＞ 0.05 ).ConclusionsNB are more likely located at adrenal gland and presented a higher incidence rate of presence of small vessels in or around the tumor which arranged in clumps or in line,vessel encased by tumor,adjacent organs invasion or metastasis and lymph node metastasis.Regular morphology,clear border and vessels displaced are more frequently observed in GNB.

Objective To investigate the effects of recombinant human granulocyte colonystimulating factor(G-CSF) on murine thymic emigration and subsets reconstitution after a sublethal dose of irradiaton.Methods Female BALB/c mice were irradiated with a 6.0 Gy of γ-ray total-body irradiation and then randomly divided into GCSF group and control group.For mice in the GCSF group,recombinant human G-CSF 100 μg · kg-1 · d-1 was injected subcutaneously once daily for 14 continuous days and mice in the control group were given the same volume of phosphate buffered solution (PBS).At 7,14,21 and 28 days later,mice were killed and thymus mononuclear cell suspension were analyzed by flow cytometry for the percentage of the four stages of thymic CD4 -CD8 - double negative cells (DN1-4) and the CD4 + CD8 + double positive ( CD4 + CD8 + DP),CD4 + CD8 - single positive ( CD4 + SP),CD4 -CD8 + single positive cells (CD8 + SP).Real-time PCR was used for detection and quantitation of murine T cell receptor rearrangement excision circles(sjTRECs) of the thymic cells of 30 and 60 d after irradiation.Results The percentage of thymic DN1 cells in GCSF group was significantly higher than that of the control group 7 d after irradiation (t =9.59,P ＜ 0.05 ).21 d later,the proportion of thymic DN3 and DN4 cells were higher than those of the control group ( t =16.37,7.6,P ＜ 0.05 ).The percentage of thymic CD4 + CD8 + DP cells decreased 7 d after irradiation,increased at 14 d,decreased again at 21 days,and then got a permanent recover.The percentage of thymic CD4 + CD8 + DP cells in the GCSF group recovered to normal and was significantly higher than that of the control group 28 days after irradiation (t =12.22,P＜ 0.05).The percentage of thymic CD8 + SP cells of the GCSF group was significantly higher than that of the control group 21 d after irradiation ( t =3.77,P ＜ 0.05 ),while G-CSF had no obvious influence on the percentage of the thymic CD4 + SP cells.The sjTRECs copies in the GCSF group was significantly higher than that of the control group 30 d after irradiation ( t =5.95,P ＜ 0.01 ),which disappeared 60 d later.Conclusions G-CSF could promote the proliferation and differentiation of thymic DN and DP cells,enhance the recent thymic emigrants and accelerate central immunologic reconstitution after acute irradiation.

Objective To explore the clinical features and endoscopic manifestations of eosinophilic gastroente-ritis(EG)in children.Methods A retrospective analysis was conducted of the clinical manifestation,laboratory examination,endoscopy(upper and/or colonoscopy)performance,diagnosis and treatment of 49 cases of patients who were diagnosed as EG in Children's Hospital of Nanjing Medical University from July 2013 to July 2015.Results The common clinical manifestations of EG in children were hematochezia(23 cases),diarrhea(20 cases),vomiting(18 cases)and abdominal pain(15 cases).The ages of children admitted to hospital for the first time ranged from 1 month and 7 days old to 13 years and 7 months old,and the mean age was 59.4 months old,in which most patients were younger than 1 year old,accounting for 38.77％(19 cases)of all.Peripheral blood eosinophilia was present in 20 cases(40.82％)of the patients,and only 6/18 cases(33.33％)of the patients had elevated serum IgE.Upon endoscopic analysis,the lesions involved esophagus(4 cases),stomach(14 cases),duodenum(20 cases),small intestine(15 cases),colon(28 cases)and rectum(6 cases),and the most common manifestation under gastroscopy was mucosal hyperemia edema(27 cases)and erosion(9 cases),while the most common manifestation under colonoscopy was mucosal hyperemia edema(25 cases)and nodular hyperplasia(24 cases).All patients improved with food restriction,in which 8 cases were treated with glucocorticoid while 9 cases with oral Singulair and 9 cases with oral Loratadine.All children with symptoms were alleviated somewhat,but 5 cases of them relapsed after drug withdrawal.Conclusions The clinical manifestations of EG in children varied and were mainly hematochezia,vomiting,diarrhea and abdominal pain.Some patients had the elevated peripheral blood eosinophilia and serum IgE.The most common manifestations under gastroscopy were mucosal hyperemia edema and erosion while the most common manifestations under colonoscopy were mucosal hyperemia edema and nodular hyperplasia.

Objective To explore the clinical aspects and related EEG characteristics of epilepsy (EP) in children with cerebral palsy (CP).Methods The clinical data and the EEG Results of seizure-interictal-period in 84 CP children complicated with EP were collected and compared with the data of 124 CP children without EP.Results Among 84 CP children complicated with EP, 46 cases (54.76%) were partial seizures. Followed 26 cases (30.95%) were infantile spasms, 6 cases (7.14%) were tonic-clonic seizures. Spastic CP children tended to be the most patients seizures in EP, it was 82.14%. Children with teraplegia CP were the most type among the spastic CP children compliated with EP. The abnormal rate of EEG of CP children complicated with EP was significantly higher than that of CP children without EP ( P＜0.001), and local epilptiform discharges and multilocal epileptiform discharges were main types.Conclusion Partial seizures is the most epilepsy type in CP children complicated with EP, and spastic CP is the main type. EEG abnormal ratio is obviously higher in the CP children complicated with EP than the CP children without EP. The types of abnormal EEG are mainly local epilptiform discharges and multilocal epileptiform discharges.

A research combined trickling filter system and active sludge aeration system was applied in the treatment of industrial wastewater from gas-generating with heavy oil. The wastewater contained both high contents of NH+4-N and mixed hydrocarbons including various PAHs. Its BOD5/COD ratio was less than 0.3 and belongs to recalcitrant, toxic wastewater. The results showed a touch-growth biofilms system was formed on the porous packing material and it played a key role in the decrease of toxicity of the influent. It could also improve the biodegradability of the wastewater.
