OBJECTIVE: To investigate the influence of aluminum hydroxide adjuvant on a murine model of allergic rhinitis (AR) and to confirm an appropriate method of establishing a mouse model of AR. METHOD: Establishing two types of BALB/c mice models of AR, one was identified as Local group which was characterized through intranasal sensitization and challenge using ovalbumin (OVA), and the other Systemic group which was made by intraperitoneal sensitization with OVA plus aluminum hydroxide and intranasal challenge through OVA. Then the numbers of sneezing and nasal rubbing were counted after the last challenge and the eosinophils in the nasal mucosa of mice models were observed and counted though Luna stain. Furthermore, morphological hyperplasia was examined in intraepithelial goblet cells and submucosal glands with HE stain. In addition, interlukin (IL) -4, IL-5, OVA specific IgE (sIgE) and interferon (IFN)-gamma in nasal lavage fluid (NLF) and serum of mice were examined u sing enzyme linked immunosorbent assay (ELISA). RESULT: The counts of sneezing and nasal rubbing in local group were more than those in systemic group and eosinophilia in the nasal mucosa of former group was greater than that in the latter one. Morphological hyperplasia was stronger in intraepithelial goblet cells and submucosal glands in local group compared with that in systemic group. Furthermore, the contents of IL-4, IL-5 and sIgE increased in the NLF and serum of mice of local group compared to those of systemic one. However, the production of IFN-gamma of mice in local group decreased when compared with that in Systemic group. CONCLUSION OVA plus aluminum hydroxide adjuvant may promote Th1 type immune response as well as Th2 response. OVA intranasal sensitization and challenge locally is an appropriate way in the establishment of AR mice models.

ObjectiveTo investigate the effect of early intervention on shoulder pain in patients with hemiplegia after stroke. MethodsStroke patients were treated with bedside physical therapy on the shoulder 7 d after onset. They were assessed with short-form McGill pain questionnaire and Fugl-Meyer assessment of upper extremity before and 40 d after treatment. ResultsThe score of MPQ in the treatment group was significantly lower than that in the control group, while the score of FMA was significantly higher(P<0.01). ConclusionEarly intervention can reduce the pain and improve the function of the shoulder in patients with shoulder pain after stroke.

Objective To develop a radionuclide parameter database on internal contamination in nuclear emergencies. Methods By researching the radionuclides composition discharged from different nuclear emergencies, the radionuclide parameters were achieved on physical decay, absorption and metabolism in the body from ICRP publications and some other publications. The database on internal contamination for nuclear incidents was developed by using MS Visual Studio 2005 C# and MS Access programming language. Results The radionuclide parameter database on internal contamination in nuclear emergency was established. Conclusions The database may be very convenient for searching radionuclides and radionuclide parameter data discharged from different nuclear emergencies, which wonld be helpful to the monitoring and assessment of internal contamination in nuclear emergencies.

OBJECTIVE To evaluate the results of superficial parotidectomy with preservation of the Steven’s duct. METHODS 27 cases of superficial parotidectomy with preservation of the Steven’s duct were reviewed retrospectively. Complications and treatment outcomes were analyzed. RESULTS Almost all cases investigated resulted in satisfactory outcomes. CONCLUSION Superficial parotidectomy with preservation of the Steven’s duct is a possible alternative for some patients, especially those with benign parotid tumour.

AIM: To investigate the clinical significance in determination of the P-selectin levels in subjects with prethrombotic state or thrombosis by flow cytometry (FCM). METHODS: The P-selectin expression on platelet membrane in 42 patients with diabetes mellitus, 33 with hyperlipidemia, 23 with cerebral infarction and 20 healthy individuals, were analyzed using fluorescently-labeled SZ-51 by direct FCM comparing with indirect FCM and enzyme-linked immunosorbent assay (ELISA). RESULTS: The level of P-selectin on platelet membrane is higher in DM (23.92%?15.83%), in hyperlipidemia (18.34%?9.46%) and in cerebral infarction (19.32%?10.38%) than normal subjects (3.38%?1.11%) (P

AIM: To study the change of intercellular adhesion molecule-1(ICAM-1) expression in intestine tissues of mice induced by LPS and regulatory effect of p38 mitogen-activated protein kinase (p38 MAPK) on ICAM-1 expression. METHODS: Protein and mRNA of ICAM-1 were measured using Western blotting and RT-PCR respectively in intestine tissue of BALB/c mice treated by lipopolysaccharide(LPS) or LPS plus SB203580, a specific inhibitor of p38 MAPK. RESULTS: Compared with control group, the expression of ICAM-1 protein and mRNA was increased significantly by LPS stimulation in dose- and time-dependent manner. ICAM-1 expression reached peak value at 12-36 h after LPS stimulation. 20.0 mg/kg of LPS could induce the maximum of ICAM-1 expression. Pretreatment of mice with SB203580 for 30 min could inhibit significantly LPS-induced expression of ICAM-1 protein and mRNA expression in mouse intestine tissues. CONCLUSIONS: These data highlight that LPS could up-regulate ICAM-1 protein and mRNA expression in intestine tissue of mice in dose- and time-dependent manner, and p38 MAPK signal pathway plays an important role in ICAM-1 expression induced by LPS. It suggests that inhibition of p38 MAPK might be a useful principle for the prevention and treatment of intestine damage of endotoxic shock.

Objective To investigate the effects of adrenocorticotropic hormone (ACTH)combined with Huaiqihuang on hypothalamic pituitary adrenal (HPA) in rats. Methods Fifty rats were randomly divided into five groups according to the random number table method:normal control group (group A), prednisone group (group B), Huaiqihuang group (group C), ACTH group (group D) and combined treatment group (group E) with 10 rats in each group. Rats in group B, C, D and E were gavaged by acetic acid prednisone water solution 12.5 mg/(kg · d) for 4 weeks to establish HPA axis suppression model. Group A was given distilled water 10 mL/(kg·d) as control. Rats in group C and E were gavaged with Huaiqihuang 5 g/(kg·d) 30 minutes after intragastric administration of prednisone acetate. At the third week of the experiment, group D and E were subcutaneous injected with ACTH 200 μg/(kg·d). The serum cortisol levels were measured respectively at the start of the ex?periment, 2 weeks and 4 weeks of experiment. Animals were sacrificed at the end of the experiment, and then weights of the pituitary, adrenal glands and the viscera index were calculated. The pathological changes of the pituitary and adrenal glands were observed by HE stainning. Results After 2 weeks, the serum cortisol levels were significantly lower in group B, C, D and E than those of group A (P<0.05), suggesting that the model was successful. After 4 weeks, the serum cortisol levels were significantly higher in group C, D and E than those of group B (P<0.05), and between the treatment group the value was group E>group D>group C (P<0.05). At the same time, the weights of pituitary and adrenal gland and the viscera in?dex were higher in the three groups than those of B group (P<0.05). The HE staining showed that there were no significant changes in the distal part of the pituitary gland in five groups. The adrenal cortex zona was thinning and the structure was dis?ordered in group B. There were different degrees of hyperplasia in group C, group D, and group E, which was the most obvi?ous in group E. Conclusion ACTH combined with Huaiqihuang can promote adrenal cortex zona hyperplasia and cortisol secretion, which reduces the glucocorticoid induced inhibition of HPA axis in rats.
