Review on licorices quality differences / 中国中药杂志

Licorice is a commonly and widely used herb, it has extensive sources. So the researches on licorice quality differences between different sources have significant meaning. This paper has reviewed the studies on licorice quality differences between different sources. Including different plant sources, habitats, variation types,production modes and cultivation conditions. It finds that there are significant differences between licorices from different sources, the quality of Licorice medicinal material is uneven.

The expression and significance of IGF-1R in nasal polyp and its relationship with allergic rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the expression of insulin-like growth factor-1 receptor(IGF-1R) in nasal polyps and its relationship with allergic rhinitis.@*METHOD@#The mRNA and protein expression of IGF-1R in 40 cases (20 cases with allergic rhinitis and 20 cases without) nasal polyps tissue (the CRSWNP group) and 20 middle turbinate tissue samples (the control group) were examined by fluorescence quantitative polymerase chain reaction (FQ-PCR) and immunohistochemistry.@*RESULT@#The positive staining rate of IGF-1R protein of nasal polyps tissue is 70.8% and that of control is 12.3%, the expression of IGF-1R mRNA of nasal polyp is 0.748 +/- 0.111,which is significant higher than that of the control group is 0.107 +/- 0.208 (P < 0.01). No significant difference of the expression of IGF-1R mRNA between with and without allergic rhinitis cases and between with and without endoscopy sinus surgery history cases in the CRSWNP group.@*CONCLUSION@#The overexpression of IGF-1R maybe play important roles in the formation of nasal polyp. Hypersensitivity reaction type I mediated by IgE has no contribution to the overexpression of the IGF-1R.

Study for the histopathologic change of ethmoid bone in patients with chronic rhinosinusitis and its correlation factors / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the histopathologic changes of ethmoid bone and its correlation with clinical types of chronic rhinosinusitis (CRS).@*METHOD@#All ethmoid bones and mucosa from 180 patients with CRS after endoscopic sinus surgery were collected for histopathologic detection with HE staining. The number and the rate of cases were counted according to different histopathologic types. To analyze the correlation between ethmoid bones and clinical types of CRS, mucosal pathologic change, the CT-scanning types of sinusitis, the course of disease as well as operational history.@*RESULT@#The ethmoid bone of all patients had varying degrees of histopathologic changes. There were 5 cases (2.78%) in stage I, 38 cases (21.11%) in stage II, 71 cases (39.44%) in stage III, and 66 cases (36.67%) in stage NIV. The histopathologic changes of ethmoid bone varied in different clinical types. In type I, there were 5 cases (8.33%) in stage I, 33 cases (55.00%) in stage II, 15 cases (25.00%) in stage III, and 7 cases (11.67%) in stage NV. In type I, there were 5 cases (8.33%) in stage II, 37 cases (61.67%) in stage mI, and 18 cases (30.00%) in stage NV. In type III, there were 19 cases (31.67%) in stage III, and 41 cases (68.33%) in stage NV. All histopathologic changes of ethmoid bone were statistically correlated (P < 0.01) with clinical types of CRS, pathologic mucosal change, the CT-scanning types of sinusitis, the course of disease as well as operational history.@*CONCLUSION@#Almost all patients with CRS manifest different-degrees of histopathologic changes, which are correlated with the clinical types of CRS, pathologic mucosal change, the CT-scanning types, the course of disease as well as operational history.

Analysis for the correlation between skin prick test and clinical characteristics in patients with chronic sinusitis with nasal polyps / 中国耳鼻咽喉头颈外科

OBJECTIVE To investigate the relationship between the skin prick test and clinical characteristics in patients with chronic sinusitis with nasal polyps(CRSwNP).METHODS Sixty cases with CRSwNP and 40 control samples underwent skin prick test with standardized allergens provided by AllergoPhamar Company,the results and their clinical characteristics are analyzed.RESULTS The positive rate of skin prick test was 81.7% and 17.5% in CRSwNP group and control group respectively(?2 =40.104,?
