Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(3):170-174
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.

2.The changes of fresh frozen plasma parameters after its off from the cold chain
Chinese Journal of Blood Transfusion 2017;30(7):699-701
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.

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.

Until now, more than seventeen parvovirus have been reported which can infect mammals and poultries. The infected cells appeared different properties of apoptosis and death, present a typical cytopathic effect. NS1 is a major nonstructural protein of parvovirus, with a conservative structure and function, which plays an important role in the viral life cycle. In addition to the influence on viral replication, the NS1 also participates in apoptosis induced by viruses. Parvovirus induced apoptosis which is mainly mediated by mitochondrial pathway, this review summarized the latest research progresses of parvovirus induced apoptosis.

Objective To investigate the effects of a training program based on virtual reality on static and dynamic balance perfor-mance in patients with Parkinson's disease (PD). Methods From June, 2014 to June, 2016, 46 patients with PD were randomly divided into control group (n=23) and experimental group (n=23). The control group received routine balance training, while the experimental group re-ceived balance training of virtual reality, for six weeks. They were assessed with Unified Parkinson's Disease Rating Scale part 3 (UP-DRS3), Berg Balance Scale (BBS), TimedUp and GoTest (TUGT) and Hamilton Depression Scale (HAMD) before and after training. The envelope area, anteroposterior standard deviation (AP-SD), mediolateral standard deviation (ML-SD) of centre of pressure (COP) were also measured with posturography. Results The scores of BBS, TUGT and HAMD improved in both groups after training (t>2.657, P<0.05), and improved more in the experimental group than in the control group (t>2.426, P<0.05). The score of UPDRS3 and the parameters of pos-turography improved in the experimental group (t>2.626, P<0.05), and improved more than that in the control group (t>2.112, P<0.05). Con-clusion Virtual reality rehabilitation is more effective than routine balance training on the static and dynamic balance function in patients with PD, and may release their depression.

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.
