Objective To explore the regularity of changes of plasma endothelin (ET), throm-boxame B2(TXB2) and 6-keto-prostaglandin F1α(6-keto-PGF1α) and restenosis after percutaneous transluminal angioplasty (PTCA) in patients with coronary heart disease. Methods Radioimmunoas-say was applied to measuring plasma levels of ET, TXB2and 6-keto-PGF1αat 0,30 min, 1 day and 3 days after PTCA in 41 patients with coronary heart disease. Results The level of ET in the patients with coronary heart disease was significantly decreased in 30 minutes after PTCA (P<0.05), but no significant difference was observed in 1 day and 3 days after PTCA (P>0.05). The level of plasma TXB2has no statistical difference after PTCA in 30minutes, 1 day and 3 days (P>0.05). The level of 6-keto-prostaglandin F1α(6-keto-PGF1α) of the patients with coronary heart disease was significantly declined in 30 minutes after PTCA (P<0.05) ,but no significant difference was observed in 1 day and 3 days after PTCA (P>0.05). Conclusion PTCA may lead to fluctuation of plasma levels of ET, TXB2and 6-keto-PGF1αThe clarification of changing regularity of these vasoactive substances contrib-utes to prevention of acute artery occlusion or restenosis after PTCA.

Objective:To evaluate the possible role of cytokines in pathophysiology and treatment of nasal polyps.Method:The expressions of Th1-typed cytokines IFN-γ、IL-2 、IL-12 and Th2-typed cytokines IL-4、IL-5、IL-8、IL-10、IL-13 were investigated with enzyme-linked immune sorbent assay(ELISA) in 25 patients with nasal polyps.Result:There was a significant upregulation of Th2-typed cytokines IL-4、IL-5、IL-8、IL-10、IL-13 in nasal polyps compared with normal nasal mucosa, especially IL-4 and IL-5 (3.9 times and 8.8 times higher than normal mucous respectively) while the expression of Th1-typed cytokines IFN-γ、IL-2、IL-12 drcreased after treated with local glucocorticoid. The levels of Th2-typed cytokines decreased significantly and Th1-typed cytokines had no obvious change.Conclusion:The upregulation of Th2-typed cytokines such as IL-4、IL-5、IL-8、IL-10、IL-12 may play an important role in the pathophysiology of nasal polyps and Th2-typed cytokines can be viewed as a target of treatment to nasal polyps.

OBJECTIVE:
To analyze the impact of β-tubulin-III (TUBB3), thymidylate synthase (TS) and excision repair cross complementation group 1 (ERCC1) mRNA expression on chemoresponse and clinical outcome of patients with advanced gastric cancer treated with TXT/CDDP/FU (DCF) regimen chemotherapy.
METHODS:
The study population consisted of 48 patients with advanced gastric cancer. All patients were treated with DCF regimen palliative chemotherapy. The mRNA expressions of TUBB3, TS and ERCC1 of primary tumors were examined by multiplex branched-DNA liquid chip technology.
RESULTS:
The patients with low TUBB3 mRNA expression had higher response rate to chemotherapy than patients with high TUBB3 expression (P=0.011). There were no significant differences between response rate and TS or ERCC1 expression pattern. Median overall survival (OS) and median time to progression (TTP) were significantly longer in patients with low TUBB3 mRNA expression (P=0.002, P<0.001). TS or ERCC1 expression was not correlated with TTP and OS. In the combined analysis including TUBB3, TS and ERCC1, the patients with 0 or 1 high expression gene had better response rate, TTP and OS than the remaining patients (all P<0.001). Multivariate analysis revealed that ECOG (Eastern Cooperative Oncology Group)≥2 (HR=2.42, P=0.009) and TUBB3 (HR=2.34, P=0.036) mRNA expression significantly impacted on OS.
CONCLUSION
High TUBB3 mRNA expression is correlated with resistance to DCF regimen chemotherapy. TUBB3 might be a predictive and prognostic factor in patients with advanced gastric cancer treated with TXT-based chemotherapy. The combined evaluation of TUBB3, TS and ERCC1 expression can promote the individual treatment in advanced gastric cancer.

PURPOSE: Hrd1 has recently emerged as a critical regulator of B-cells in autoimmune diseases. However, its role in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) remains largely unexplored. This study aimed to examine Hrd1 expression and B-cell accumulation and their possible roles in CRSwNP. METHODS: Quantitative real-time polymerase chain reaction, immunohistochemistry, enzyme-linked immunosorbent assay and Western blotting were used to assess gene and protein expression in nasal tissue extracts. Cells isolated from nasal tissues and peripheral blood mononuclear cells were characterized by flow cytometry. Local antibody production was measured in tissue extracts with a Bio-Plex assay. Additionally, changes in Hrd1 expression in response to specific inflammatory stimuli were measured in cultured dispersed polyp cells. RESULTS: Nasal polyps (NPs) from patients with eosinophilic CRSwNP (ECRS) had increased levels of Hrd1, B-cells and plasma cells compared with NPs from patients with non-eosinophilic CRSwNP (non-ECRS) or other control subjects (P < 0.05). The average Hrd1 levels in B-cells in NPs from ECRS patients were significantly higher than those from non-ECRS patients and control subjects (P < 0.05). NPs also contained significantly increased levels of several antibody isotypes compared with normal controls (P < 0.05). Interestingly, Hrd1 expression in cultured polyp cells from ECRS patients, but not non-ECRS patients, was significantly increased by interleukin-1β, lipopolysaccharide and Poly(I:C) stimulation, and inhibited by dexamethasone treatment (P < 0.05). CONCLUSIONS: Differential Hrd1 expression and B-cell accumulation between the ECRS and non-ECRS subsets suggests that they can exhibit distinct pathogenic mechanisms and play important roles in NP.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
