RESUMO
Objective:To report one case of renal clear cell carcinoma transferred to the nasal cavity and sinuses treated by low temperature coblation assisted nasal malignant tumor resection under nasal endoscopye, and to review the associated literatures.Methods: Under nasal endoscope, the tumor was removed along the lateral wall of the nasal cavity with bipolar electrocautery and coblation.The vaseline gauze was used to stop bleeding, and the tumor was completely removed.Results: The intraoperative frozen section showed a capillary hemangioma.The patient was diagnosed as metastatic renal cell carcinoma to the nasal cavity and sinuses by the results of pathology and immunohistochemical staining.The postoperative recovery was uneventful and the nasal packing was removed 3 d after operation.Conclusion: Renal clear cell carcinoma transferred to the nasal cavity and sinuses is rare;under nasal endoscope, surgical resection is a good procedure to control metastasis.
RESUMO
OBJECTIVE@#To assess the effect of CPAP therapy on sleep quality and quality of life in patients with moderate or severe OSAHS.@*METHOD@#Seventy-two patients diagnosed as OSAHS by polysomnography (PSG) were assigned to receive CPAP therapy for 3 months. At baseline and three months after treatment patients underwent polysomnography (PSG). Analyze the results of PSG, sleep quality, excessive daytime sleepiness, quality of life and the general well-being.@*RESULT@#The lowest average oxygen saturation and the average blood oxygen saturation improved significantly after CPAP therapy, and the longest sleep apnea time and AHI decreased obviously (P < 0.01). Except body pain, the other seven dimensions of SF-36 improved obviously (P < 0.01); ESS, PSQI and GWB also improved (P < 0.05).@*CONCLUSION@#For patients with moderate or severe OSAHS, CPAP therapy can obviously improve the sleep quality, excessive daytime sleepiness, improve patients' life quality and the general well-being.

Objective To explore the effect of triptolide(TL) combined with hyperthermia on proliferation and apoptosis of Hep-2 cells and its affect on cell cycle phases,and provide theoretical foundation for treatment of laryngocarcinoma.Methods Hep-2 cells at logarithmic growth phase were randomly divided into control,hyperthermia,TL,TL combined with hyperthermia groups.MTT method was adopted to investigate the proliferation inhibition rate of the Hep-2 cells.Cell cycle and apoptotic rate of Hep-2 cells were analyzed by flow cytometry,and then the changes of subcellular structures were observed by electron microscope.Results The proliferation inhibition rates in hyperthermia,TL,TL combined with hyperthermia groups were 21.2%,28.5% and 54.5%,respectively;the proliferation inhibition rate in TL combined with hyperthermia group was higher than those in hyperthermia and TL groups(P

Objective To investigate the proliferation inhibition of chlorpromazine combined with taxol on Hep-2 cells (human laryngeal carcinoma cell line) and the effects on cell cycle progression. Methods Hep-2 cells at logarithmic growth phase were divided into taxol groups(3.0,6.0 and 12.0 mg?L-1),chlorpromazine(12.0 mg?L-1) comined with taxol (4 mg?L-1)group and control group (100 mL culture fluid).MTT and flow cytometry were used to detect the proliferation inhibition rates of Hep-2 cells in various groups.Flow cytometry was also used to analyze the cell cycle progression of Hep-2 cells and apoptotic rate after administration.Results The proliferation inhibition rates in 3.0,6.0 and 12.0 mg?L-1 taxol groups were 14.0%,23.9% and 36.7%,respectively,there were significant differences between three groups(P
RESUMO
BACKGROUND: Adhesion molecules are closely associated with inflammation. Inflammation due to white blood cell (WBC) infiltration and free radical injury following brain ischemia are believed to be important factors contributing to the pathogenesis of multi-infarct dementia.OBJECTIVE: To determine the level of serum adhesion molecules and free radicals in patients with multi-infarct dementia to explore the relationship between their levels and multi-infarct dementia.DESIGN: A case-control trial.SETTING: Department of Neurology, Second Affiliated Hospital of Jilin University.PARTICIPANTS: Totally 82 patients with multi-infarct dementia were hospitalized in the Department of Neurology, Second Affiliated Hospital of Jilin University between January 2000 and December 2004. These patients included 32 cases of mild dementia, 21 of moderate dementia, and 29 of severer dementia. The normal controls were 23 concomitant healthy volunteers who came for routine physical examination.METHODS: Enzyme-linked immunosorbent assay (ELISA) and electron spin resonance were used to determine the level of serum soluble intercellular adhesion molecules (ICAM) and vascular cell adhesion molecules (VCAM), as well as oxygen free radical concentration in the normal controls and patients with multi-infarct dementia, and the association between the severity of the illness and the levels of adhesion molecules and oxygen free radicals was analyzed.MAIN OUTCOME MEASURES: Serum levels of ICAM-1 and VCAM-1 and oxygen free radical concentration in the two groups.RESULTS: Totally 82 patients with multi-infarct dementia and 23 healthy controls were included in this study and all enter the result analysis. In multi-infarct dementia patients, the serum levels of soluble ICAM-1 and VCAM-1 and oxygen free radical concentration [(469.00±76.33), (196.00± 45.91) and (1 103.30±98.96) μg/L, respectively] were significantly higher than those of the control group [(601.00±76.30), (4.018±1.656), and (1.295±0.718) μg/g, respectively, t=5.517-6.754, P ＜ 0.01], and the 3 indices were positively correlated with the severity of dementia (r=0.659 4,r=0.697 2, r=0.649 4, respectively, P ＜ 0.05); serum ICAM-1 and VCAM-1 levels were positively correlated with the concentration of oxygen free radicals (r=0.714 7, r=0.732 4, respectively, P ＜ 0.01).CONCLUSION: Serum ICAM-1, VCAM-1 and oxygen free radicals might be implicated in the pathophysiological development of multi-infarct dementia, and their levels increase in parallel with the severity of dementia.
