ABSTRACT
OBJECTIVE@#To explore the role in the pathogenesis of nasal polyp (NP) by comparison of eosinophil major basic protein (MBP), and neutrophil elastase (NE) in nasal polyps (NP) epithelium, stroma and the secretion of expression.@*METHOD@#Immunohistochemical detection of 30 cases of patients with chronic sinusitis (CRS) NP epithelium NE stroma and the expression and secretion of MBP.@*RESULT@#1. There were significant differences of the expression of NE and MBP in epithelial tissue, stroma and secretion compared with the control group (P 0.05), while there was significant difference between epithelial tissue and the secretion (P < 0.05); 3. There were significant differences of the average positive expression of MBP and NE among epithelial tissue, stroma and secretion (P < 0.05); 4. MBP and NE were usually degranulated in secretion, while usually located in eosinophils (Eos) and neutrophils (Neu) in epithelial and mesenchymal; 5. There were abundant expression of MBP and NE in epithelial shedding regional, while small amounts of expression in stroma and integrated epithelial; 6. Electron microscopy could show the characteristics of electron density of MBP and NE particles.@*CONCLUSION@#MBP and NE collaborated to cause pathological effects on the occurrence of NP.

OBJECTIVE: To study the mechanism of herbal application along meridians for treatment and prevention of asthma by using serum pharmacological test to observe the effects of serum containing herbs against the constriction of tracheal spiral strips induced by acetylcholine chloride (Ach). METHODS: Guinea pigs were randomly divided into normal control group, normal saline (NS) application group, aminophylline application group, aminophylline injection group, 1-day herb application group, 7-day herb application group and 14-day herb application group. Asthma was induced by Hutson's method in guinea pigs except the normal control group. Guinea pigs in herb application groups were treated by external application of a compound herbal medicine 60 min once every day. Guinea pigs in NS application group were treated by external application of NS. Guinea pigs in the two aminophylline-treated groups were treated by external application and intraperitoneal injection of aminophylline at a dose of 400 mg/kg, respectively. The guinea pigs were killed and the sera were obtained after 1-day, 7-day and 14-day treatment in the three herb application groups, 7-day treatment in the NS application group, the aminophylline application and injection groups, respectively. Serum pharmacological method was used to do the experiment, the effects of different sera on the constriction of tracheal strips were observed, and the constriction rates were calculated. RESULT: The serum containing herbs had an effect in reducing the constriction of tracheal spiral strips induced by Ach, and the effect was similar to that of the serum obtained from the aminophylline injection group. The constriction rate of the tracheal spiral strips was decreased when herbal application treatment was prolonged within a period of time, and it became stable when herbal application treatment was between 7-14 days. The constriction of tracheal spiral strips induced by Ach could be reduced remarkably when it was previously treated by serum containing herbs. CONCLUSION: The anti-acetylcholine function with a time-dependent effect is one of the mechanisms of herbal application treatment along meridians for asthma, and furthermore, herbal application treatment along meridians might be useful for preventing asthma.
ABSTRACT
To observe the curative effect and the hemodynamic change of cervical vertigo treated by acupuncture, 66 patients were randomly divided into two groups: group A in which acupoints Yuzhen (BL 9) and Fengchi (GB 20) were used and Group B in which Cervical Jiaji points (C4-6) were used. Before and after treatment, the symptom of the cervical vertigo and the grade variety of function and the change of Color Doppler Flow Imaging (CDFI) of vertebral artery were observed. After treatment, the grade in two groups increased, there was a remarkable difference between two groups(P ＜ 0.05); after treatment, the grade of vertigo degree increased, there was a remarkable difference between two groups(P ＜ 0.05); needling Yuzhen (BL 9) and Fengchi (GB 20) can remarkably improve the symptom of cervical vertigo and vertebral artery blood flow rate, and the curative effect was superior to needling Jiaji points.
