Objective To investigate the expression and significances of DPP-4 and IL-6 in febrile seizures(FS).Methods FS were induced in Sprague-Dawley(SD) rats at P14 in a hot water bath by using classical model of hyperthermia-induced seizures.A genome-wide microarray experiment was generated in the rats.The relationship between the differentially expressed genes were analyzed by the method of bioinformatics, and the gene and protein levels of DPP-4 and IL-6 were detected by QPCR,WB and ELISA.Selected 50 children with FS(FS group) and 25 healthy children(control group), and to compare the gene and protein levels of DPP-4 and IL-6 between the two groups.Results Interaction network diagram of differential gene expression showed that there may be interactions between DPP-4 and IL-6.Animal and clinical experiments showed that the DPP-4 and IL-6 gene and protein levels were significantly higher in FS group compared with control group(P<0.05).Conclusion There were high gene and protein expressions of DPP-4 and IL-6 in the FS group compared with the control group.These results indicated that immune and inflammations may play an important role in the FS, and it has provided an attractive pharmacological target for the treatment of FS in clinic.

Objective To analyze the reasons of the emergency patients forgoing the invasive rescue therapy and to put forward the corresponding strategy.Methods According to whether the patients accepted the invasive rescue therapy or not,2 673 patients in resuscitation room of Peking Union Medical College Hospital were divided into rescue group (group R) and do not rescue group (group DNR).There were 2 147 cases in group R and 526 case in group DNR.The rescue consent form or do not rescue consent form was required to sign by patient self,patient' s family member or relatives.The patient' s basic information,underlying disease,payment of medical expenses,personnel who signed the consent form,treatment and prognosis in both groups were investigated.Results There was no significant gender deference in both groups (x2 =1.86,P =0.173).The mean age of patients in group DNR was much higher than that in group R (69.5 ±-12.5 vs.58.6 ± 19.2 years,F =28.92,P =0.000).The proportion of patients outside Beijing in group DNR was higher than that of group R (51.90% vs.44.01%,x2 =10.59,P =0.001).The ratios of chronic heart failure,chronic respiratory failure,chronic hepatic encephalopathy,chronic renal failure,malignant tumor in group DNR were significantly higher than that of group R (8.17% vs.3.03%,8.17% vs.2.61%,3.80% vs.1.16%,5.32% vs.1.44%,11.98% vs.2.28%,all P=0.000).The proportion of patients without insurance in group DNR was higher than that of group R (52.09% vs.41.08%,x2 =20.87,P =0.000).Except the ratio of patients self signing the consent form in group DNR was higher than that of group R (3.04% vs.0.42%,x2 =64.40,P =0.000),there were no significant deference in other people who signed the consent form such as patient's offspring,spouse,parents,siblings and others.Univariate and multivariate logistic regression analyses showed older age,non Beijing patients,chronic underlying diseases,without insurance and patients self signing the consent form were the major risk factors on refusing the invasive rescue therapy.The mortality rate of group DNR was much higher than that of group R (19.39% vs.7.68%,x2=64.40,P=0.000).Conclusions Most of patients who refused to accept invasive rescue therapy were elderly people or in condition of end stage of chronic disease.The doctors and nurses in emergency department should continue to take care of these patients and make use of noninvasive methods to treat them or relieve their pain.

Objective To investigate the factors and rate of the forming of the collateral feeding arteries from inferior phrenic artery(IPA) in hepatocellular carinoma(HCC).Methods IPA was demonstrated on angiographs in 137 patients with HCC during transcatheter arterial chemoembolization(TACE),TACE was performed through diaphragmatic inferior artery(DIA) super setectively.Results Of 137 cases,21 cases underwent TACE through DIA(15.3%),of them 2 cases were recurrent after surgical operation(9.5%),3 cases had the tumor receive blood supply from IPA at first TACE(14.3%) and 16 cases were occured after TACE tow and more times(76.2%).Conclusion Collateral branches originated from IPA are important feeding arteries in HCC,TACE of IPA can be performed with a high success rate without major complications.

AIM: This study was designed to investigate the protective role of hypobaric hypoxic pretreatment (HHPT) on hippocampal neurons in Babl/c inbred mice. METHODS: HHPT was produced by simulating a 7 000 m high altitude 2.5 h/d for 3 d. At 36 h after last time decompression, three subgroups consisted of both the control and pretreatment mice were subjected to the 12 000 m high altitude hypobaric hypoxia for 4 h, the severe ischemia produced by bilateral common carotid artery occlusion for 18 min, and the severe ischemia/hypoxia produced by permanently ligation of right lateral common carotid artery followed by a 8 000 m high altitude hypobaric hypoxia for 4 h, respectively. The extents of protection to hippocampal CA1 neurons by HHPT were evaluated by accounting the number of intact neurons between HHPT and control group. RESULTS: The results indicated that HHPT protected hippocampal neurons against severe hypobaric hypoxia, severe ischemia, and ischemia combined with hypobaric hypoxia. CONCLUSION: Hypobaric hypoxic pretreatment induces a delayed protection to hippocampal neurons against hypoxic and ischemic injuries.
