Objective To analyse the differences between idiopathic and symptomatic childhood epilepsy with occipital patoxysms. Methods The medical records of 38 patients with interictal spikes and/or sharp waves over occipital areas,posterior temporal-parietal areas,or both were retrospectively analysed.Epidemiological data,ictal symptoms,electroencephalogram,neuroimaging studies,treatment response and prognosis were compared using chi-square test or Mann-Whitney U test. Results Four patients of idiopathic group had positive family history related to nervous system.Seizures were more frequent in symptomatic group than in idiopathic group.Both groups showed autonomic symptoms,while ictal vomiting and deviation of eyes were more common in the presence of Panayiotopoulos type.The prognosis of idiopathic group was much better than that of symptomatic group. Conclusion Panayiotopoulos syndrome is more common.Neurologic deficits and electroencephalographic characteristics are major factors to predict seizure remission in children with occipital lobe epilepsy.Idiopathic childhood epilepsy with occipital paroxysms may result in better prognosis.

Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of cells of myeloid origin that comprises myeloid progenitor cells and immature macrophages, which expand in tumorbearing mice and patients' bone marrow, spleen and peripheral blood and recruit to the tumor site. MDSC express high levels of arginase 1 (ARG1), inducible-nitric oxide syntheses (iNOS), reactive oxygen species (ROS) and peroxynitrite. They could suppress T-cell functions by cell contact or not, and induce regulatory T cells (Treg), all of the above are its weapons to defend individuals' immune system. Anti-tumor strategies targeted at MDSC develop rapidly now. In this review, we briefly introduce the strategies that targeted at MDSC and their mechanisms.

Non-responding pneumonia describes the situation, in which an inadequate clinical response is present de-spite antibiotic treatment. The incidence of treatment failure in community acquired pneumonia (CAP) can range up to 31%. At present, the diagnosis and treatment of this kind of disease remain a great challenge to CAP. For this reason, several stud-ies have attempted to establish risk factors and new strategies for the treatment of non-responding pneumonia. This article re-views the progress of the pathogeny and treatment of non-responding CAP.

By the traditional Chinese medicine obtaining-pulse equipment coupled with pressure living like flexibility transducer and B-ultrasound scarching unit,collecting demic radial artery signal on cunkou,with the key link of four pulse tracings attributes in term of "position","rate","shape" and "force",each detecting indexes were analyzed synchronically with press pulse wave and ultrasound vas dynamic state changing trendgraph.According to the time lock analysis of electrocardiogram marking method and radial artery pulse wave,the theory approach of pulse tracings digitization were undertaken,and the scores of four attributes on pulse tracings were determined as well.

Objectives: To improve the procedures for establishment of focal cerebral ischemic rat models with the intraluminal suture method and to elevate the survival rate of the models. Methods: Sixty male SD rats (weight, 250-270 g) were randomly allocated into 3 groups (n =20 in each group). Control group used the conventional surgical method, the pterygopalatine arteries were exposed and ligated during the procedure, and the rats had free access to food after the procedure; gavage group used the same method as the control group, but postoperative gavage was performed; protective group did not ligate the pterygopalatine arteries, but the carotid arteries and vagus nerves were carefully separated. Trying to avoid stretching the vagus nerves during the procedure and postoperative gavage was performed. The body weight of the rats in each group was weighed continuously before and after modeling, and the neurological deficit scores were measured; the survival rate of rats in each group was calculated at day 3, 14, and 28, respectively after modeling; the brain infarct volume in each group was calculated at day 28 after modeling. Results: Circled digit oneThe mean time of model production was 19.5 min in the protective group, and it was shorter than that in the control and gavage groups. The differences were statistically significant (P < 0.05); Circled digit twoAt day 3 after modeling, the survival rate of the rats in the protective group was higher than that in the control and gavage groups. The differences were statistically significant (P < 0.05); Circled digit threeAfter modeling, the body weight of the rats in the 3 groups were all decreased. The body weight of the rats in each group began to increase from day 7 after modeling. The body weight of the rats in the protective group was all higher than that in the control and gavage groups at day 7, 14, 21, and 28 after the procedure. The differences were statistically significant (P < 0.05); Circled digit fourthere were no significant differences comparing the neurological deficit scores and cerebral infarction volume among the 3 groups. Conclusion: The improved procedures could shorten the time of model production, regain body weight quickly, improve the survival rate effectively after establishment of the cerebral ischemic rat models.

Background p16INK4a gene plays an important role during the aging and senility.So it was well known to be a leading gene associated with aging.Corneal endothelial cells(CECs) always get trapped in the G1 phase due to the lack of proliferative ability.Whether it is relative with cell senescence is unclear.Objective This study was to investigate the expression ofp16INK4a gene and Bmi1 gene in human CECs from different aged donors ex vivo.Methods The corneal rims,the residual of corneal tissue preserved in DX solution after penetrating keratoplasty,was used in the present study.Parameters were recorded for the donor,including the age,death to preservation interval and preservation to surgery interval.Corneal endothelium survival rate and endothelial cell density were evaluated by trypan blue-alizarin red dying immediately after penetrating keratoplasty.Routine haematoxylin and eosin staining was also performed to proof the normal structure of the cornea.Sections of corneas from different aged donors were classified into ＜30 years group,30-50 years group and ＞50 years group and were immunostained to assess the expressions of p16INK4aprotein,Bmi1 protein and Ki67 protein in CECs.Total RNA was extracted from independent corneal sample for the evaluation of p16INK4a mRNA,Bmi1 mRNA and Ki67 mRNA expression in CECs by quantitative real-time PCR(qRT-PCR).Results The endothelial cell density of each group was (3069 ±172),(2748±64),(2444 ±178)cells/mm2,respectively.Haematoxylin and eosin staining showed the normal structure of corneal epithelium,stroma and endothelium.qRT-PCR examination revealed an age-related increase in p16INK4a mRNA expression in the CECs(F =5.703,P =0.014) and a decrease in Bmi1 mRNA and Ki67 mRNA expression (F =3.950,P =0.042;F=548.500,P =0.000).The further comparison verified a significant elevation in the expression of p16INK4a mRNA in the CECs of the ＞50 years group compared with ＜30 years group and significant decline in Bmil mRNA and Ki67 mRNA the expression (P =0.006,0.013,0.000).Immunohistochemistry in situ confirmed the expression and nuclear localization of p16INK4a protein in CECs,and the expressing intensities of Bmi1 and Ki67 proteins in the elder donors were weaker than those of the younger donors.The immunofluorescence exhibited that the expressing intensity of p16INK4a protein in CECs of 58 years old donor was higher than that of 23 years old donor,showing a consistent result with that of qRT-PCR.Conclusions Expression of p16INK4a gene increases and that of Bmi1 gene decreases upon age.These results suggest that p16INK4a gene is associated with senescence of human CECs.

Objective To investigate the proliferation inhibition and apoptosis induction effect of thalidomide(Thal) and its joint effect with 5-Fu on MGC-803 cell line. Methods The morphological changes of MGC-803 cells with AO/EB stain were observed under fluorescence microscope. The proliferation inhibition effeet was evaluated with MTT. The apoptosis induction effect was determined by FAM. Results The results of MTr array were as below: the difference was significant between Thai groups of 25 mg/L or above concentration and the control group (P＜0.05), 5-Fu of all testing concentrations showed significant difference compared with the control gToup(P＜0.01). For combined groups with the same concentration of 25 mg/L 5-Fu,combined groups showed distinct difference from the corresponding 5-Fu group (P＜0.01), but two combined groups showed no distinct difference with each other (P＞0.05). For combined groups with the same concentration of 5-Fu 12.5 mg/L, 5-Fu plus 50 mg/L or 100 mg/L Thai showed no distinct difference from 5-Fu group of 25 mg/L(P＞0.05). With FAM study, all test groups showed significant difference compared with the control group (P＜0.01). There was also significant difference between two test groups arbitrarily (P＜0.01).Conclusion Both Thai and 5-Fu could inhibit the proliferation and induce the apoptosis of MGC-803 cells.The effect is reinforced with the combination significantly. Combination with Thai could decrease the concentration of 5-Fu but have the similar effect.
