Objective:To explore the therapeutic effect of the use of budesonide for externally-used budesonide in the surgical cavities following endoscopic sinuous surgery(ESS).Method:122 cases with chronic sinusitis were randomly divided into two groups treated by the routine procedures after endoscopic sinuous surgery but the treatment group with 61 cases were treated by the addition of budesonide suspension for inhalation in the surgical cavities.The process of the epithelization in the surgical cavities by endoscopy was investigated.Result:The process of cleaning in 15 days in the surgical cavities was better in the budesonide-using group than in the controlled group.A significant difference was found(P

Objective To study the clinical effect of minimally invasive treatment of 24 patients with hemor-rhagic moyamoya disease.Methods The clinical features of onset,bleeding location of the lesions and the type,ther-apeutic results of minimally invasive treatment were studied retrospectively.Results 24 patients with hemorrhagic moyamoya disease spontaneous intracerebral hematoma who need to acutely remove the hematoma were examined by CT angiography ( CTA) .Emergency minimal invasive puncture was performed according to the result of CTA,and the role of CTA in operation was analyzed.In all 24 patients,most of them were cerebral hemorrhage breaking into ventri-cles,5 cases with intracranial aneurysm.In all the hemisphere of hemorrhage,dilatation and abnormal branching of the AchA and P-CoM were observed in 9 patients,superficial temporal artery.Conclusion Minimally invasive treat-ment of hemorrhagic moyamoya disease scheme is simple,practical and effective,the maneuverability is strong.

0.05).No significant difference was seen between the 2 groups in IgE,ECP,but within-group,except for oreillons,coxsackie,and there were significant differences in IgE and ECP(Pa0.05).Conclusions Montelukast can ameliorate clinical symptom and BHR subsequent to bronchiolitis after non-RSV infection,and decrease the asthma formation rate,and there are no significant differences in montelukast′s clinical effect among different etiological agents.

Objective To explore relationships of expression of hypoxia?inducible factor?1α(HIF?1α), vascular endothelial growth factor(VEGF)and protein kinase B(P?Akt)with angiopoiesis and cell apoptosis. Methods Biopsy specimens were collected from skin lesions of 32 patients with lichen planus and normal skin of 20 patients with lipomyoma, and subjected to paraffin embedding. Immunohistochemical staining was performed to measure expression of HIF?1α, VEGF and P?Akt, and TUNEL technique was used to detect apoptosis of keratinocytes in these paraffin?embedded tissue sections. Microvessel density (MVD)was assessed by counting CD34?labeled vascular endothelial cells. Results HIF?1α, VEGF and P?Akt were moderately or strongly expressed in lichen planus lesions, but absent or weakly expressed in normal skin of controls, and the expression of HIF?1α, VEGF and P?Akt was significantly higher in the lichen planus group than in the control group (all P < 0.01). HIF?1α was mainly expressed in nuclei of keratinocytes, while VEGF and P?Akt were expressed in the cytoplasm of keratinocytes. In addition, the lichen planus group showed significantly increased MVD(21.27 ± 6.54 vs. 10.26 ± 1.10 microvessels/high?power(200 ×)field, t = 5.607, P < 0.01)and apoptosis rate of keratinocytes(72.81% ± 9.234% vs. 28.16% ± 3.464%, t = 8.431, P < 0.01) compared with the control group. Pearson correlation analysis showed that there were positive correlations between HIF?1αand VEGF expression, between VEGF and P?Akt expression, and between P?Akt and HIF?1αexpression in the lichen planus group(r=0.625, 0.453, 0.455, respectively, all P<0.01), and expression of HIF?1α, VEGF and P?Akt was all positively correlated with MVD(r=0.721, 0.646, 0.671, respectively, all P<0.01). Conclusion HIF?1αand its downstream target genes VEGF and P?Akt may play a certain role in the occurrence of lichen planus.

Objective To study the effect of automobile exhaust pollution saturation of carboxyhemoglobin (COHb) in traffic policemen. Methods 169 traffic policemen working outdoors were selected as a exposure group and 112 traffic policemen working indoors as control group in a traffic policemen detachment in Tangshan. Questionnaires and health examination were conducted in two groups. The carbon monoxide levels in the exhalation were measured in 281 traffic policemen by a micro_smokerlyzer and the corresponding saturation of carboxyhemoglobin (COHb) were read. Results The higher saturation of carboxyhemoglobin were observed in exposure group (2.30%?1.49%) compared with those (1.71%?0.99%) in control group (P

Objective To investigate the activity changes of gelatinase in the formation of ascending aortic aneurysm.Methods Thirty five young Wistar rats were divided into two groups:the control group and the experiment group.The rat models induced by ascending aorta banding were made.The ascending aortas were taken after 3-5 months operation,changes of gelatinase activity was observed by gelatin zymography and film in situ zymography.Results Gelatinase activity of ascending aortic aneurysm was significantly increased compared with that of normal ascending aortic aorta.Conclusion Elevation of gelatinase activity may play a significant role in the formation of ascending aortic aneurysm.

The cell culture technology is the basis for the postgraduate students to undertake researches in furure.The department of cell biology of our university carried out the teaching reformation on the cell culture course by means of writing outstanding teaching materials, making supporting DVD, arranging suitable teaching contents and plans and setting up flexible examining systems, which promoted the teaching effects and profited students to master this skill quickly.

Objective To investigate the inhibitory effect of recombinant LIGHT-Fe gene on the proliferation of human esophageal carcinoma cell line Eea109. Methods LIGHT-Fc expression vector was transfected into human esophageal squamous carcinoma cell line Eca109 by using DOTAP liposomal transfection reagents. The effects of LIGHT-Fc gene on the proliferation of esophageal carcinoma cell line Eca109 in vitro were detected by cell growth curve and MTr assay. Forty-five nude mice were equally divided into Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group. Carcinogenesis and pathological expression of the esophageal carcinoma tissues were observed. Results The expressions of LIGHT receptors were detected in Eca109 cells. The proliferation of Eca109 cells was inhibited after trasfecting LIGHT-Fc gene into Eca109 cells. The numbers of tumors generated in Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group were 12, 11 and 5, with statistical significance between Eca109/LIGHT group and the other two groups (X2 =6.652, 4.821, P <0.05). The result of histopatholagical examination indicated that the tissue necrosis appeared significantly in tumors derived from Eea109/LIGHT cells. Conclusions The growth of esophageal squamous carcinoma cell line Eca109 can be suppressed by LIGHT-Fc gene whether in vitro or in vivo.

Objective To probe into the epidemic feature, pa tho genic spectrum and main risk factors of diarrhea during the field training in ar my. Methods Detection of morbidity,investigation of risk factor s and detachment of pathogen were performed. Results The diarrh eal incidence rate of army of field training was 4.36%(106/2 433), which was higher than that of hold garrison(0.98%, 2/204). The incidence rate of officers was lower than that of soldiers. Two incidence peaks concerned with the army motion course were foun d. The detection rate of lapactic bacteria from fecal of patients was 63.1%(65/1 03) and most of them were ETEC, followed by the plesiomonas shigelloides. Se ven ind ividual factors concerned with diarrhea disease were found with logistic analysi s, including dr inking unboiled water, going out to eating and so on. Conclusions Incidence of diarrhea in the army increased obviously during the field training and the chief pathogen are ETEC and plesiomonas shigelloides, at the same time, t he occurrence of diarrhea is related with many individual factors.
