OBJECTIVE: To investigate the characteristics and influence factors of sensitization hy allergens in patients with allergic rhinitis in the junction of Guangdong and Guangxi provinces. METHOD: One thousand one hundred and twenty-four patients who were diagnosed with allergic rhinitis hy clinical history and symptoms underwent a skin prick test. The percent of allergens with positive skin response and Multiple Allergens Positive Scores were recorded, and their influence factors, included age, gender and test period were evaluated. RESULT: The percent of top three inhalant allergens with positive skin tests were as follow: dermatophagoides pteronyssinus (77.0%) ,dermatophagoides farina (77.1%), blattella germanica (42.3%); the percent of top three ingested allergens with loositive skintests were as follow: crab ( 39.5%), shrimp (31.1%), ribbonfish (10.8%). The average Multiple Allergens Positive Score was (3.6 +/- 2.7). The percent of allergens with positive skin response and Multiple Allergens Positive Score of different allergens changed as age, gender and text period changed, and the changing trend of them was accordant. The percent inhalant allergens with positive skin tests in dermatophagoides pteronyssinus, dermatophagoides farinae and cat fur in different gender showed a significant difference. CONCLUSION Acarine allergens were the most common allergens in patients with allergic rhinitis in the junction of Guangdong and Guangxi provinces. The percent of allergens with positive skin response and the severity of multiple allergy were influenced by age, gender and text period. The severity of multiple allergy can be measured by Multiple Allergens Positive Score.

Objective To discuss the changes of the quality of the fresh frozen plasma,which leaved refrigerator and it was out of the cold chain.Method The fresh frozen plasma was placed at the room temperature,in six different periods,that is 0,0.5,2,4 h,8,and 12 hours.The prothrombin time,activated partial thrombin live enzymes time,fibrinogen and factor FⅤ,factor FⅧ,antithrombin(AT) and protein C were tested on each point.Results In the fourth group and the fifth group,the FⅧ,AT,and protein C were statistically lower compared with the controls (P＜0.05).But there were no obvious changes of APTT,PT,INR,Fbg and FⅤwhen placed at room temperature for 12 hours.Conclusion After the fresh frozen plasma placed at room temperature for more than 8 hours,the FⅧ ∶ C,AT and protein C were significantly lower compared with the control group.But they have no obvious changes of APTT,PT,INR,Fbg and F Ⅴ when placed at room temperature for 12 hours.

As a rising medical science,evidence-based medicine should be extensively used.Applying the principle of evidence-based medicine to the clinical teaching of burns has positive significance for improving teaching quality,which is helpful to the cultivation of students'clinical thinking abilities.

Drug resistance is the main restriction factor for clinical usage of taxanes.This review concentrates on drug-resistance mechanisms of taxanes that include drug target change,avidity change between drug-target interaction,decrease of cellular effective drug concentration,downstream cellular responses to a drug target molecular lesion,and cell cycle regulation-mediated drug resistance.

Objective　To study the relationship between atherosclerotic plaques in carotid artery and ischemic cerebrovascular diseases. Methods　The extracranial carotid arteries (ECA) and middle cerebral artery (MCA) of 54 patients with transient ischemic attack (TIA) or cerebral infarction (CI) were examined with doppler ultrasound. The distribution of atherosclerotic plaque, degree of stenosis and ultrasounic classification of ECA and the mean velocity of blood flow in MCA were examined. Results　①Stenosis over middle-grade on asymptomatic side in extracranial internal carotid artery (EICA) in group of patients with TIA was significantly higher than symptomatic side(P<0.01). Stenosis over high-grade on asymptomatic side in ELCA in group of patients with CI was significantly higher than symptomatic side (P<0.01). ②Flat and soft plaque are most common in group of patients with TIA or CI, then are hard and ulcerative plaques. Incidence of soft plaques on asymptomatic side in group of patients with TIA or CI are significantly higher than symptomatic side (P<0.01); ③Among the group of patients with CI, mean velocity of MCA decreased on asymptomatic side in 31 cases (68.9%), and significantly higher than symptomatic side (P<0.01). Conclusion　Atheroclerotic plaques in carotid artery and intracranial hemodynamic characteristics are the important risk factors for ischemic cerebrovascular diseases. These findings have important values in predicting subsequent TIA or CI in asymptomatic subjects.

Objective To determine the expression of glial fibrillary acidic protein(GFAP) and vascular endothelial growth factor(VEGF) in the hippocampus of rats with Alzheimer's disease(AD), and to determine the effect of butylphthalide on them and its significance. Methods Sixty male adult rats were randomly divided into a model group, a Butylphthalide group, and a control group. AD models were established by injecting β-amyloid protein 1-42 into the hippocampus of rats. Sixty days later,the rats were sacrificed and both sides of the hippocampus were sectioned for immunohistochemistry. Results Positive cells of GFAP in the hippocampus of the model group increased and the expression of VEGF decreased statistically, compared with the control group(P<0.01). The positive cells of GFAP in the hippocampus of the butylphthalide group decreased and the expression of VEGF increased significantly, compared with the model group(P<0.05). Conclusion Butylphthalide may protect the neuron-vascular unit of the hippocampus of Alzheimer model rats by inhibiting the expression of GFAP and increasing the expression of VEGF.

A retrospective analysis was carried out in 36 patients with blunt diaphragmatic rupture during March 1991 and March 2006. Twenty-two diagnoses were confirmed preoperatively, and the rest 14were confirmed perioperatively. Three patients underwent surgical treatment after no response to conservative therapy. Thoracotomy was performed in 21 patients, laparotomy in 9, thoracotomy plus laparotomy in 5 and combined thoraco-laparotomy in 1. Most diaphragmatic rupture may be caused by blunt collision and could lead to thoracoabdominal injury. In spite of high mortality rate, the condition is usually under diagnosed. Definite diagnosis and timely operation are important to increase survival rate and reduce mortality.

Objective To discuss color Doppler uhrasonographic (CDU) grading of varicocele (VC) in predicting the changes of the fertility index (FI) after varicocelectomy.Methods One hundred and fifty-one patients with VC were diagnosed and graded by CDU.All patients were grouped by the regurgitant volume and the maximum diameter of pampiniform plexus veins(PPV).The relation between the regurgitant volume and the maximum diameter of PPV and the changes of the FI after varicocelectomy was analyzed.Results The pathological regurgitation could be detected when the PPV diameter > 1.5 mm.The positive correlation was observed between the regurgitant volume and the diameter of PPV (r = 0.89, P <0.01).The pre- and postoperative FIs were extremely significant difference in regurgitation grade Ⅱ and regurgitation grade Ⅲ (P < 0.01) but not significant difference in regurgitation grade Ⅰ (P>0.05).The pre- and postoperative FIs were no significant difference in the group with the PPV diameter ≤ 2.0 mm (P > 0.05), but statistically significant difference in the groups with the diameters 2.1-2.5 mm and 2.6-3.0 mm (0.01 < P <0.05).FIs in the group with the diameter > 3.0 mm exhibited extremely significant difference after varicocelectomy (P < 0.01).Conclusions CDU grading of VC could be used to predict the changes of seminal quality after varicocelectomy.Varicocelectomy isn't necessary to the patients with VC that the PPV diameter ≤ 2.0 mm or pathological regurgitation being detected only on Valsalva maneuver.
