The systemic anaphylaxis murine model was induced by the injection of oval albumin (OVA)in aluminum hydroxide gel adjuvant. The death rate varied with the mouse species: 40-90% in Swiss and 69% in average,no death in C57BL/6 and 615 but some symptoms. developed. Swiss mice was adopted in this experiment.90% of mice pretreated with Lx remained living after allergen challenge,but only 20% in normal control. For elucidation the possible mechanism of Lx action,the study was carried out on detection of anti-OVA IgE specific antibody and histamin concentration in lung tissues. Passive cutaneous anaphylaxis(PCA)titers for anti-OVA IgE antibody in serum ranged from undilution to 160 in control group and not detectable in group pretreated with Lx. In addition, after absorption of PCA positive sera with anti-IgG antibody.the PCA activity was not affected. Histamin content was 1.54?0.24?g/ml in Lx treated mice caopared to 2.69?0.67?g/ml in control group(p

OBJECTIVETo understand the situation of studies and development of international acupuncture and moxibustion in 2006 by analysis on the acupuncture-related articles embodied in Medline data-base in 2006.

METHODSA total of 881 articles in Medline data-base of the ISI knowledge Web were retrieved by "acupuncture", "moxibustion", "acupressure" and "cupping" as key words, then 761 articles excluding unrelated 120 ones were analyzed and concluded for distribution of the article sources, periodicals source, type, research contents and methods.

OBJECTIVETo study the efficacy and safety of specific sublingual immunotherapy with dermatophagoides farinae drops in the treatment of cough variant asthma in children.

METHODSA total of 106 children aged 4-14 years old with cough variant asthma and positive skin prick test responses to dermatophagoides farinae allergens were randomly divided into two groups: SLIT group (n=53), which received specific sublingual immunotherapy with dermatophagoides farinae drops as well as standardized treatment and conventional treatment group (n=53), which received standardized treatment alone. Improvement in cough/asthma symptom scores and the time taken for symptoms to improve were observed after treatment. Serum eosinophil (EOS) level and peak expiratory flow (PEF) were measured after treatment. The side effects were observed.

RESULTSCompared with the conventional treatment group, the SLIT group showed significant decrease in symptom scores and serum EOS level and significant increase in PEF (P<0.05). The time at which symptoms began to improve in the SLIT group was earlier than in the conventional treatment group (P<0.05). The effective rate in the SLIT group was significantly higher than in the conventional treatment group (85% vs 68%; P<0.05). Local reactions such as redness, swelling, and itching occurred in some children of the SLIT group but disappeared on the following day.

CONCLUSIONSSpecific sublingual immunotherapy with dermatophagoides farinae drops is an effective and highly safe treatment for cough variant asthma in children.

OBJECTIVE: The purpose of the study was to observe the three-dimensional (3D) CT imaging features of the frontal recess region with 3D reconstruction, and obtain the real image of the important anatomical structures of the region to conduct surgery. METHOD: Five patients were undergone spiral CT by 16 line high speed spiral CT, and multiplanar reconstruction images using standard 3D reconstruction protocol on a computer workstation. The structure of the frontal recess, the agger nasi cell and adhere style of the uncinate process were observed. The parameter of the important anatomic structure of frontal recess was measured precisely. RESULT: After the reconstruction, we get the 3D model very close to the true state of the nasal cavity--sinuses cell, in which parts of the frontal recess can clearly identify the agger nasi cell, frontal cell and other important structures. In this patient, the height, width and depth of the agger nasi and frontal sinus were 12.3 mm, 12.1 mm, 38.5 mm, respectively. CONCLUSION This study tried to develop the standardized techniques and measurements from 3D reconstructed images of the frontal sinus and to ascertain the usefulness of the frontal sinus in identification of patients. The results in better preoperative patient counselling and in predicting postoperative improvement in clinical status.

Objective To investigate the correlation between the CT perfusion and microvessel density (MVD),expression of vascular endothelial growth factor(VEGF)in neoplasm of head and neck.Methods Eighty-eight lesions of head and neck were scanned by spiral CT.The largest axial surface of the mass was searched on unenhanced imaging,and at this level the dynamic contrast enhanced scan series was acquired.Time-density curves (TDC)were created from circular or oval regions of the interest drawn over the mass,target artery by Toshiba Xpress/SX spiral CT with perfusion functional software.The parameters were measured including:peak height (PH ),peak time (PT ),mean transit time (MTT), contrast enhancement ratio(RPH),and perfusion flow (PF).Histopathological slides of 35 masses were carefully prepared for the anti-CD34 and VEGF immunohistochemical staining and tumor microvessel density and calculation of VEGF expression scores.The parameters of CT perfusion were correlatively study with MVD and VEGF.Results(1)The TDC of CT perfusion imaging could be classified into 3 types.The TDC of 53/77 (68.9% )malignant tumors presented the type with rapid ascending and rapid descending after injecting contrast.The TDC of 6/9 malignant lymphomas showed low platform curve。(2)The PF median of thyroid carcinoma was 82.2(41.0,183.4)ml?min~(-1)?100 g~(-1).There was significantly difference in the parameters of CT perfusion among thyroid carcinoma and squamaous cell cancer (Median 23.8 (7.0, 108.4)ml?min~(-1)?100 g~(-1))and lymphomas (Median 24.5(13.2,78.6)ml?min~(-1)?100 g~(-1)).(3) MVD in benign tumors was (44.7?3.4),and in malignant tumors,it is (49.6?14.8 ).There was no significantly difference in MVD between benign and malignant tumors.High VEGF expression was found in 15 malignant tumors and 1 benign tumors,low VEGF expression was found in 9 malignant tumors and 10 benign tumors.(4)There were no significantly difference in VEGF expression and MVD.There was good correlation between MVD (M 40.0 )and PH (M 26.9 ),RPH (M 14.5 ),PF (M 46.8 )(r = 0.35,45.49, 0.41 ).There was correlation between VEGF(M 4.0)and MTT(M 16.7 )(r = -0.41 ).Conclusion The TDC and CT perfusion could be helpful to differentiate benign from malignant tumors. CT peffusion in neoplasm of head and neck is correlated with MVD and VEGF,and may reflect MVD and expression of VEGF.

OBJECTIVE: To systematically evaluate the clinical efficacy of nasal high-frequency ventilation (nHFV) in the treatment of neonatal respiratory distress syndrome (NRDS). METHODS: A literature search was performed in PubMed, Cochrane Library, EMBase (Ovid), Chinese Biomedical Literature Database, Chinese Journal Full-text Database, Wanfang Data, and Weipu Data to collect the randomized controlled trials (RCTs) that compared the clinical efficacy of nHFV and nasal continuous positive airway pressure (nCPAP) in the treatment of NRDS. A Meta analysis was performed on the included RCTs using Rev Man 5.3 software after data extraction and quality evaluation by Cochrane 5.1.0. RESULTS: A total of 4 RCTs involving 218 patients were included. The Meta analysis showed that compared with the nCPAP group, the nHFV group had a significantly better treatment outcome (RR=1.73, 95%CI: 1.39-2.15, P<0.00001). There were no significant differences in the incidence rates of intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, necrotizing enterocolitis, pneumothorax and retinopathy of prematurity. CONCLUSIONS Compared with nCPAP, nHFV has better clinical efficacy in the treatment of NRDS, without increasing the risk of related complications.

Objective To investigate factors that affect treatment compliance with oral antiretroviral agents and figure out the corresponding nursing intervention to improve treatment compliance of AIDS patients. Methods To study on treatment compliance with oral anti-retroviral agents and viral loads of 389 patients with AIDS before and after nursing intervention during the period of anti-retroviral treatment.Results Among 389 cases, 108 cases had non-compliance with anti-retroviral agents. The reasons for noncompliance mainly came from losing heart or depression to prospect of anti-retroviral therapy, deficiency in medical science, side effects, social discrimination, and bad self-control ability, and so on. Through health education and nursing intervention, the treatment compliance as well as efficacy of anti-retroviral therapy(percentage of viral load at undetectable level ) has been significantly improved compare with patients without the corresponding nursing intervention ( P＜ 0.001 ). Conclusions Health education and nursing intervention can significantly enhance treatment compliance and efficacy of anti-retroviral agents of patients with AIDS.
