Objective To discuss the influence of clean-up frequency of the operative cavity on the curative effect after endoscopic sinus surgery.Methods 368 patients with sinusitis or nasal polyps were randomly divided into observation group and control group,184 patients in each group.Control group was treated with operative cavity cleaning in moderate frequency,while observation group in intensive frequency.Results The obvious effective rate of observation group was 80.98％,which was significantly higher than that of control group(69.02％) (x2 =12.468,P ＜0.05).The ineffective rate of observation group was 2.17％,which was significantly lower than that of control group (9.78％) (x2 =15.717,P ＜ 0.05).The recurrence rate of observation group was 11.96％,which was significantly lower than that of control group (26.09％) (x2 =9.361,P ＜ 0.05).Conclusion The clean-up frequency of the operative cavity after endoscopic sinus surgery can influence curative effect,moderate clean-up frequency can significantly improve the treatment effects and deserved promotion.

[ABSTRACT]AIM:Toexploretheeffectsofchrysinoninsulinresistance(IRe)inamousemodel.METHODS:Male C57 mice were randomly divided into control group , IRe group, low-dose chrysin group ( IRe+chrysin-low) and high-dose chrysin group (IRe+chrysin-high).After 24 weeks, the body weight, liver index and fat mass in all mice were detected.The blood glucose , insulin level and HOMA-IR were measured to determine the changes of the insulin resistance in the animals.The oxidative stress (SOD, GSH-Px and MDA) was also measured.The mRNA expression of insulin sig-naling pathway molecules (IR, IRS1, IRS2, Glut2 and Glut4) and inflammatory factors (TNF-α, IL-1β, IL-6 and NF-κB) was analyzed by real-time PCR.The protein levels of IRS1 and p65, and their phosphorylation were detected by West-ern blot.RESULTS:After 24-week intervention , the indicators in IRe group were higher than those in control group , in-cluding body fat deposition, serum glucose, serum insulin, HOMA-IR and liver oxidative stress (P<0.01), indicating that the model of insulin resistance was successfully established .Low dose and high dose of chrysin decreased the body weight, serum glucose, serum insulin and HOMA-IR in the IRe mice (P<0.05).The liver oxidative stress was also re-duced in both groups (P<0.05).However, no statistical difference of the indexes between IRe +chrysin-low group and IRe+chrysin-high group was observed.Chrysin upregulated the mRNA expression of IR , IRS1, IRS2, Glut2 and Glut4 (P<0.05), and down-regulated the mRNA expression of various inflammatory factors .The inhibitory effect of chrysin on the mRNA expression of NF-κB was observed (P<0.05), especially in high dose group (P<0.05).It was confirmed that the effect of chrysin on liver IRe was related with the increase in the p-IRS1 levels and decrease in the p-p65 levels by Western blot .CONCLUSION:Chrysin inhibits obesity , hyperglycemia and hyperinsulinemia , and relieves insulin resist-ance and oxidative stress , which might be closely related to the regulation of insulin signaling pathway and the inhibition of inflammatory factor expression .

Transcranial doppler (TCD) was used to measure the flow velocities of middle cerebrial artery (MCA) in 4 patients of clinical brain death. The reaults showed that the changes were similar in all the patients studied; 1) the dierotic notch (DN) was deeper in the spectrum of flow velocities of MCA, end diastolic flow rate (VD) significantly decreased, and the pulastility index (PI) increased ; 2) VD decreased progressively; 3) all patients showed characteristic to-and-fro TCD pattren with antegrade flow in systole and retrograde flow in diastole; 4) the pattern totally disappeared when the patients were claimed dead. It is found that TCD is valuable for the determination of brain death.

Objective:Toinvestigate the influence of MMP7 antisense oligodeoxynucleotide(ASODN)on adhesion and invasion ofhuman lung adenocarcinoma cell line A549.Methods:Phosphorothioate MMP7 ASODN was transfected to A549 cells mediated by liposome. The expression of MMP7 was examined by RT-PCR.The adhesive and invasive ability were examined by plate adhesion model and Boyden Chamber transwell assay.Results:After MMP7 ASODN was transfected,the relative optical density(ROD)of electrophoresis strip was decreased obviously(P

Objective To analyze the pathophysiological variation in patients with penetrating cardiac trauma (PCT) and discuss the classified treatment strategies.Methods A retrospective analysis was conducted on pathogenetic condition,medical interventions and other clinical information of 133 PCT patients.The patients were divided into four groups in accordance with their symptom classification on arrival at emergency department,including sub-clinic type,cardiac tamponade type,hemorrhagic shock type and agonal type.Meanwhile,the patients were classified into three groups according to their pathogenesis phase,including sub-clinical phase,clinical phase and agonal phase.Development characteristic of patients' condition in each group was investigated in each time point by survival analysis.Impacts of medical interventions on prognosis of those patients were analyzed,such as pericardial space exploration,emergency room thoracotomy (ERT),operating room thoracotomy (ORT).Results Some patients at sub-clinical phase were aggravated into clinical phase or agonal phase,as well as some patients at clinical phase were aggravated into agonal phase during in-hospital treatment.There were significance differences of posttraumatic suvival course among the four groups,namely sub-clinical type,cardiac tamponade type,hemorrhagic shock type and agonal type (P ＜ 0.01).The differences of posttraumatic survival course were also significant among the three groups,namely sub-clinical phase,clinical phase and agonal phase (P ＜ 0.01).Conclusion Clinical symptom classification (or pathogenesis phase) of PCT may not be always unchangeable,thus it is recommended that PCT patients should be treated based on their clinical symptom classification or patbogenesis phase at consultation.

Conclusion: It made the detection of output characteristics more convenient and avoided the occurrence of false and missing detection.

Objective To investigate the effect of selectiveα1 adrenergic receptor blocking agent in the treatment of bladder neck contracture caused by refractory urinary tract infection in elder.Methods 70 cases of bladder neck contracture were selected and randomly divided into two groups, 35 cases each.Two groups received Ceftriaxone sodium 1 g qd at acute episode,Levofloxacin Hydrochloride 0.5 g tid at non acute phase,control group received the treatment of urethral dilatation, Terazosin hydrochloride 10 mg qd, the experiment group received more with Tamsulosin Hydrochloride Sustained 0.2 mg qd.Two groups were both treated for four weeks.Urinary dynamics index, international prostate symptom score,quality of life score, clinical symptom disappearance time, the number of daily spasm and adverse reactions were compared.Results After treatment, the total effective rate in the experiment group(94.29%) was higher than the control group(65.71%)(P<0.05).Maximum and the average urinary flow rates in two groups increased after treatment(P<0.05), residual urine volume, maximum urethral closure pressure decreased(P<0.05), international prostate symptoms and quality of life score decreased(P<0.05); and compared with the control group, maximum and the average urinary flow rates in the experiment group were higher(P<0.05), residual urine volume, maximum urethral closure pressure were lower(P<0.05), international prostate symptoms and quality of life score were lower(P<0.05), and the average duration of symptoms of bladder neck spasm and the number of daily spasm in the experiment group were significantly shorter than the control group ( P <0.05 ).There was no significant difference in adverse reactions between the two groups. Conclusion Selectiveα1 adrenergic receptor blocking agent in the treatment of bladder neck contracture caused by refractory urinary tract infection in elder was effective, and it can improve the patient's urine flow rate, reduce the residual urine level, increase the quality of life.
