Objective To summarize the clinical and electroencephalography(EEG) characteristics of benign epilepsy with centro-temporal spikes (BECTS) in children.Methods The clinical manifestations,EEG findings,response to drug treatment and prognosis of 35 children with BECTS from Jul.2003 to Dec.2008 in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively.Results In the 35 cases,the age of onset was 2.5 to 14.0 years old,and the peak age of onset was 6-10 years old(62.9%).Twenty-two cases mainly presented partial seizures:hemifacial convulsions,sialorrhea,sounds,limb tonic-clonic seizures,and secondary generalized seizures.Thirteen cases were only describled generalized tonic-clonic seizures.Seizures were closely related to sleep and almost occurred shortly after falling asleep or before waking up.There were 26 cases who displayed convulsion during sleeping,including noon break.The EEG features showed numerous or single spikes on one side or both sides in the central and temporal areas under the background of normal activity in interictal period.The release frequency of abnormal wave was significantly increased after falling asleep,so the EEG monitoring during sleep could improve the positive rate of BECTS.Monotherapy with low-dose anti-epileptic drug could obtain good efficacy.Twenty-five cases stopped seizures within 3 months after therapy.Thirty-three cases hadn't get seizure since drug therapy at the age of 16 years old.So far,12 cases had been stopped medicine.Conclusions BECTS mostly begins at school-aged children,which displays partial seizures or secondary generalized seizures.The seizures are closely related to sleep.EEG monitoring during sleep which shows numerous or single spikes on the centrotemporal area has crucial diagnostic value to BECTS.There is a positive response to monotherapy with low-dose anti-epileptic drug and generally the prognosis is good.

Objective To explore the temporal and spatial expression pattern of tenascin-c(tnc) and tenascin-w(tnw) in zebrafish early development,to further explore the role of tenacsin in zebrafish embryo development,and the association between them.Methods Zebrafish embryos at 2 hours post fertilization(hpf),4 hpt,8 hpt,10 hpf,24 hpt,48 hpr,72 hpf and 7 days post fertilization(dpf) were collected to extract RNA for reverse transcription-polymerase chain reaction(RT-PCR) and fix the embryos at different stages for in situ hybridization.Temporal and spatial expression pattern of tnc and tnw on different stages of zebrafish early development was observed.Results tnc and tnw all expressed in zebrafish from 24 hpf to 7 dpf,but did not expressed from 2 hpf to 10 hpf.Tnc expressed at pharyngeal arch,notochord,somite in 24 hpf,then weakly expressed at somite,but highly expressed at otic vesicle,pectoral fin and hindbrain in 48 hpf,and tnc was expressed at hindbrain,pharyngeal and notochord and disappeared at somite and pectoral.tnw expressed at hindbrain,midbrain and otic vesicle in 24 hpf,expressed at somite,notochord,hindbrain,otic vesicle and pharyngeal in 48 hpf.In 72 hpf,tnw expressed weakly at somite and notochord.Conclusions Zebrafish tnc and tnw have special temporal and spatial expression pattern,and share partial overlapping expression pattern.

Objective To explore the expression pattern of tenascin-c(tnc)gene in zebrafish embryo abnormal development which was induced by ethanol,and to further understand the function of tnc gene in embryo develepment.Methods Zebrafish were treated with ethanol at different concentration from 100 to 500 mmol/L,and embryos at 24 and 48 hours were collected and fixed,then tnc expression pattern was observed by in situ hybridization and reverse transcriptase-polymerase chain reaction(RT-PCR).Results The result of RT-PCR showed that ethanol at 100 and 200 mmol/L could increase the expression of tnc,while the result of in situ hybridization showed that,while ethanol at 300 mmol/L and above decrease the expression of tnc in presumptive position at 24 hours,and ethanol at 100 mmol/L and above caused increase expression of tnc in zebrafish heart.Conclusions tnc is increased when treated with 100 and 200 mmol/L ethanol and is presented in the abnormal development of hearts of zebrafish,which can promote the normal development of embryos in some degrees.The expression pattern of tnc in pathologic state is highly conserved in all vertebrate,and in adult and embryos as well.

Objective To review and evaluate the effect of one stage surgical correction of congenital heart disease with tracheal stenosis in infants.Methods Between August 2001 and December 2005,six infants with congenital heart disease with tracheal steno- sis were repaired at one stage operation.The age was 24 d～3 y[mean(13.16?12.03)months]and the weight was 4.2～10.0 kg [mean(7.98?2.03)kg].There were 3 patients with tetralogy of Fallot,1 with pulmonary atresia;2 with ventricular septal defect, 1 with coarctation of aorta;and 1 with pulmonary sling.The congenital heart disease were repaired underwent low temperature and car- diopulmonary bypass,and the tracheal stenosis were corrected simultancously.Results There was one death postoperative because of right and left branch stenosis.One patient with pulmonary sling died of granulation tissue on the patch 3 months after operation.All other 4 patients recovered uneventfully.These patients were followed up from 6 month to 4 years.There were no complications.CT scan shows that the tracheal anastomosis was patent without any stenosis.Conclusion One stage repair of congenital heart disease with tracheal stenosis in infants may have a satisfactory result.To deal with the tracheal stenosis is difficult,the operative methods de- pends on the length of stenosis.The principles of surgical methods consist of using autologous material,maintaining its contour and function of respiratory epithelium,and maintaining its growth.

OBJECTIVETo investigate the correlation between the pathological and image features of different subtypes of retroperitoneal liposarcoma.

METHODSPathological and image characteristics of 21 retroperitoneal liposarcomas were retrospectively analyzed comparing their different histopathological subtypes.

RESULTSThis series consisted of 11 well-differentiated, 4 myxoid, 3 round-cell, 2 pleomorphic and 1 dedifferentiated liposarcoma. Well-differentiated liposarcomas were predominantly composed of lipoma-like and sclerosing components. On CT and MRI image, the attenuation and signal intensity of lipoma-like components resembled those of fat, whereas the signal intensity of sclerosing components was similar to those of muscle. Unenhanced CT image of the myxoid subtype showed density resembling that of water. On contrast-enhanced CT image, it showed gradual reticular or sheet-like enhancement. The CT and MRI image appearance of the round cell and pleomorphic subtypes resembled those of nonfatty soft tissue masses with foci of necrosis. The dedifferentiated liposarcoma showed the image feature of a well-differentiated component clearing enhanced soft tissue mass.

CONCLUSIONDifferent subtypes of retroperitoneal liposarcoma show different CT and MRI features relating to their major histologic components. A good understanding of the relation between their radiological and pathological features is helpful to arrive at a correct diagnosis for retroperitoneal liposarcoma.

OBJECTIVETo design DNA microarray and investigate the molecular anti-tumor mechanism of herbs of traditional Chinese medicine.

METHODcDNA microarrays consisting of 56 probes representing 24 human cell cycle genes were constructed, Four anti-hepatocarcinoma herbs including Radix Linderae, Hebra Artemisiae Annuae, Radix Amebiae, Radix Astragli, were chosen. Effects of herbs on SMMC-7721 cell cycle were observed by flow cytometry assay. Effects of herbs on cell cycle gene expression in SMMC-7721 cells were analyzed by comparing hybridization of Dig-Labeled cDNAs from herb-treated cells and cDNAs from untreated cells.

RESULTExpressions of cell cycle geneswere changed in different degrees after herbs treated. Some genes were down-regulated and some genes were up-regulated. The changes in gene expression agreed with the results of flow cytometry assay.

CONCLUSIONThe results suggest that these herbs may have effects on cell cycle and DNA damage checkpoint genes which may be the mechanism of the herbs, and DNA microarray can be used to investigate the biological function of extracts of traditional Chinese medicine.

Objective To evaluate the solute clearance characteristics of REXEEDTM series dialyzers during high-flux dialysis, and explore the care characteristics. Methods A randomized crossover study of 3×3 Latin square was designed based on different dialyzers. Eighteen patients with regular hemodialysis underwent dialysis with REXEEDTM-15AC dialyzer, REXEEDTM-15UC dialyzer and controlled APS-15U dialyzer, respectively. Blood samples were obtained from the blood flow entrance and exit of dialyzers, levels of urea nitrogen, creatinine, phosphate and β2-microglobulin were detected, and solute clearance rates were calculated. Before and after the third dialysis with each dialyzer, blood samples were obtained to measure the levels of urea nitrogen and creatinine, and the rates of decrease were calculated. The vital signs of each patient were intensively observed, and the venous pressure and transmembrane pressure were monitored from the dialyzers. Results The urea nitrogen clearance rates of REXEEDTM-15AC dialyzer and REXEEDTM-15UC dialyzer were significantly higher than that of APS-15U dialyzer (P<0.05). The creatinine clearance rate of REXEEDTM-15AC dialyzer was significantly higher than that of APS-15U dialyzer(P<0.05). There was no significant difference in the rate of decrease in blood urea nitrogen among different dialyzers of the same patient(>65 % for all patients). The vital signs were stable with no adverse events during dialysis, and there was no abnormal findings in laboratory security parameters. Conclusion REXEEDTM series dialyzers are effective and safe for clinical application. Great importance should be attached to the complaints from patients during dialysis. For those with less ultrafiltration, fluid as well as uhrafiltration should be supplemented to increase the transmembrane pressure.

BACKGROUND AND OBJECTIVEConcurrent chemoradiotherapy for cervical carcinoma develops rapidly and has become a common and standard therapy in recent years. Both the local control rate and survival rate of patients were increased and the risk of death fell by 30%-50%. This study aimed to explore the efficacy of concurrent chemoradiotherapy plus adjuvant chemotherapy on and the treatment compliance of the patients with advanced cervical squamous cell carcinoma.

METHODSA total of 156 patients with stage IIa-IIIb cervical squamous cell carcinoma were randomly divided into the concurrent chemoradiotherapy group (experimental group) and radiotherapy group (control group). Intracavity and external beam radiation therapy were administered. At point A, 40-48 Gy were given by 10-12 fractions; at point B, 46-50 Gy were given by 23-25 fractions. In the same time, experimental group was treated by cisplatin (DDP, 40 mg) on day 1, repeated every week. Ten days after radiation therapy, TP regimen was administered as adjuvant chemotherapy.

RESULTSFor the experimental and control groups, the objective response rates were 88.61% and 75.32%, 1-year survival rates were 88.57% and 70.77%, 1-year local control rates were 81.43% and 64.62%, 3-year survival rates were 82.14% and 57.69%, and 3-year local control rates were 75.00% and 46.15%, with significant differences (P<0.05). Quality of life of all patients were significantly improved after treatment (P<0.05).

CONCLUSIONConcurrent chemoradiotherapy plus adjuvant chemotherapy for advanced cervical cancer can improve short-term and long-term survival and local control rates of patients, improve the quality of life, and the toxicity can be tolerated.
