Objective To study the effect of electromyographie biofeedback on visceralgia hypersensitivity in patients with refractory irritable bowel syndrome (IBS) and the relationship between psychological factors and vis-ceral hypersensitivity. Methods Sixty patients with refractory IBS were enrolled in this study and received electro-myographic biofeedback treatment for 4 weeks. The threshold of visceralgia, and scores on the Hamilton anxiety rating scale (HAMA) and the Hamilton depression rating scale (HAMD) were evaluated before and after treatment. Re-suits Compared with the baseline values, the threshold of visceralgia increased significantly during treatment(P≤ 0101) and the total scores on both the HAMA and HAMD had declined significantly (P≤0.01) by the end of 4, weeks of treatment. The evolution of the index of the threshold of visceralgia was negatively correlated with the evolu-tion of both the HAMA and HAMD scores (r = -0.543, P≤0.01; r = -0.728,P≤0.01). Conclusion Elec-tromyographic biofeedback treatment can elevate the threshold of visceralgia hypersensitivity in patients with refractory IBS. Anxiety and depression might contribute to visceralgia hypersensitivity in IBS.

The present study was designed to confirm the use of GM-CSF, made by the Beijing United Biological Engineering Company, in leucocytopenia after chemotherapy in 12 patients with malignant tumor. In patients with malignant tumor the interval leucocytopenia needed shortened 5 days compared with that in control subjects. At the same time GM-CSF could be resistant to infection significantly, especially in patients with complicated infection, and the antibiotic applying time decreased. In addition, clinical experence had shown that there was no obvious side-effects in general dosage. Thus, these findings indicate that GM-CSF is a kind of essential drug in radical chemotherapy in patients with tumor.

Objective To investigate the pathological features of airway remodeling and evaluate interventional effects of nerve growth factor (NGF) on the expression of matrix metalloproteinase-9 (MMP-9), an important mediator of airway remodeling, in guinea pig asthma model. Methods Guinea pigs were randomly divided into the control group, asthma group, and antibody NGF intervention group (each group had 8 guinea pigs). In the asthma group the animals were sensitized by repeated exposure to aerosolized ovalbumin combined with Al(OH)_3. The thickness of the smooth muscle of intrapulmonary bronchi was measured by image analysis system. The expression of MMP-9 in bronchi and lung tissues were assayed with immunohistochemistry combined with the micro-image analysis system. The levels of MMP-9 mRNA in bronchi and lung tissues were determined by RT-PCR. Results After repeated allergen challenge, obvious infiltration of inflammatory cells and proliferation of goblet cells and smooth muscle were demonstrated in guinea pig bronchi. Expression levels of MMP-9 in the epithelial cells of bronchi were significantly higher in asthmatic animals than those of control group animals. Compared with asthmatic group, there was mild inflammation reaction, and decrease in collagen deposition and expression of MMP-9 in antibody NGF group animals, and they were not significantly higher than that in control group animals. Conclusions Repeated exposure of allergen induced airway inflammation and remodeling. MMP-9 plays an important role in airway remodeling. Antibody NGF intervention could inhibit airway remodeling through inhibition of the expression of MMP-9.

Background and purpose: At present, the treatment of elderly patients with ovarian cancer, espe-cially advanced ovarian cancer, tends to be conservative, and elderly patients often can not receive standard treatment. There are few treatment experiences and research data. This study aimed to investigate the treatment outcome, survival and prognostic factors of elderly patients with advanced epithelial ovarian cancer. Methods: This study retrospectively analyzed the clinical data for women older than 65 years diagnosed with stage Ⅲ and Ⅳ epithelial ovarian cancer between Apr. 2008 to Dec. 2012 in Chongqing Cancer Hospital. Results: Of the 181 women who met study criteria, 8.8% received no treatment, 12.7% underwent surgery alone, 15.5% received chemotherapy alone, 33.2% underwent non-standard treatment, 29.8% underwent standard treatment. Baseline comparison of different treatment methods showed that the proportion of patients with cardiovascular and cerebrovascular diseases was lower in the standard treatment group. After Correcting the effect of cardio-cerebrovascular diseases, the median survival time of standard treatment (48 months) and the median survival time of non-standard treatment (47 months) were significantly longer than that of the other treatment groups (P<0.001). The median survival time of chemotherapy alone (26 months) was significantly longer than that of the surgery alone and untreated group (P<0.001), while the median survival time of surgery alone was similar to untreated group (9 months vs 8 months, P=0.269). Multivariate analysis using Cox model showed that treatment, residual lesion size, cardio-cerebrovascular diseases significantly impacted on survival time. Conclusion: Standard treatment was still the key factor for the best survival of elderly women with advanced ovarian cancer. When this is not offered or possible, chemother-apy alone offers better survival than surgery alone. However, surgery alone does not improve prognosis.

The expressions of estrogen receptor (ER) α,ERβ1,and ERβ2 in thyroid carcinoma,thyroid adenoma,and adjacent normal thyroid tissue were determined by RT-PCR and immunohistochemistry,and the relationship of expression levels of three ERs and the main clinical pathologic parameters were evaluated.The result showed that ERα mRNA expression in papillary thyroid carcinoma(PTC) tissues was significantly higher than adjacent normal tissue,while,ERβ2 mRNA expression in PTC tissues was significantly lower than normal tissue ( P<0.05 ).The positive expression of ERβ1 and ERβ2 in the thyroid carcinoma was related with the histological variant of carcinomas; the ERβ2 expressions were related with the lymph node metastasis and TNM staging of the carcinomas.These results suggest that the decreased ERβ2 expression may induce proliferation and carcinogenesis of thyroid follicular epithelial cells as well as progression of the carcinoma,and is a powerful prognostic indicator.
