Objective To investigate the clinical characteristics, diagnosis, treatment and prognosis of malignant fibrous histiocytoma (MFH) of thyroid. Methods The clinical case and follow-up data (n=3) of MFH of thyroid from our hospital between 2000 and 2007 was analyzed, with the correlating references reviewed. Results MFH of thyroid accounted for 0.574% (3/523) of malignant tumor of thyroid. MFH of thyroid progressed so fast as to invase recurrent laryngeal nerve (RLN) and /or cervical lymph nodes. Conclusions The diagnosis of MFH of thyroid is difficult, for it is easy to be misdiagnosed as thyroid carcinoma. Immunohistochemistry pathology can provide a good differential diagnostic value, with CK negative, Tg negative, and Vimentin positive to support the diagnosis of MFH. Extensive and thorough excision should be the main choice to treat MFH of thyroid. Patients of MFH of thyroid often died of recurrence or metastasis in 2 years after operation. MFH of thyroid is a kind of rare thyroid primary tumor, with malignancy of high grade and poor prognosis. The disgnosis of MFH of thyroid depends on immunohistochemistry staining, while excision should be the main choice for treatment.

Objective To investigate the effect of Pingfei Oral Liquid (POL) on the distribution of mast cells (MCs) and the expression of interleukin 6 (IL-6) in the lung tissue of radiation pneumonia rats. MethodsForty-five SD rats were randomized into 3 groups : normal control,model group and POL group. The rat model of radiation lung fibro-sis was set up by a single X-ray dose of 20Gy irradiation over the whole chest of the rats. POL (20 g·kg-1·d-1,once a day, five times a week) was given orally one week before irradiation and the treatment lasted 5 weeks. MCs in the lung tissue were stained with toluidine blue firstly and then were counted 2, 4 and 8 weeks after irradiation. IL-6 protein expression of lung tissue was measured by immunohistochemical assay 8 weeks after irradiation, and mRNA ex-pression was determined with RT-PCR 4 weeks after irradiation. ResultsIt's showed the aggregation of large amount of pulmonary mast cells and increase of IL-6 protein expression 8 weeks after irradiation (P < 0.01).IL-6 mRNA expression in the irradiated lung of rats increased 4 weeks after irradiation (P < 0. 01). POL could reduce the aggrega- tion of MCs (P < 0. 01) and the expression of IL-6 protein (P < 0. 01) and mRNA (P < 0. 05) in the lung tissue. ConclusionPOL can prevent radiation pneumonia in rats by reducing the aggregation of mast cells and inhibiting IL-6 expression in the lung tissue.

Objective: This study investigates the effect of docetaxel + oxaliplatin + S-1 (DOS program) in treating advanced gastric cancer and surgical safety assessment. Methods: Fifty patients with advanced gastric cancer admitted to the Department of Gastrointestinal Surgery, The Affiliated Tumor Hospital of Xinjiang Medical University between January 2011 and May 2012 were enrolled in this study. These patients were randomized into the observation arm (n=25) and the control group (n=25). The observer group was administered three cycles of chemotherapy using a DOS program before surgical treatment, whereas the control group underwent surgery. Results: Compared with the control group, the clinical response rate (64.0%), D2 lymph node dissection rate (88.0% vs. 64.0%), and R0 resection rate (92.0%vs. 68.0%) in the observation group were significantly higher (P<0.05). Moreover, the number of postoperative lymph node metastasis in the observation group was significantly less than that in the control group (3.2±2.5 vs. 6.3±2.9, P<0.05). The operative time (230.5 min±45.6 min vs. 205.6 min±42.4 min) and intra-operative blood loss (425.5 mL ±115.4 mL vs. 210.6 mL±125.6 mL) of the two groups were sta-tistically significantly different (P<0.05). The incidence of postoperative complications and lymph node sweeping number of the two groups showed no significant difference (19.6 ±2.8 vs. 21.2 ±2.0, P>0.05). The patients exhibited good tolerance to chemotherapy, with bone marrow suppression and gastrointestinal reactions as the main adverse effects. Conclusion:The DOS program is a highly efficient, advanced gastric cancer neoadjuvant chemotherapy. The program can improve patient survival and has good patient tolerance and compliance, good peri-operative safety, high R0 resection rate, and low postoperative lymph node metastasis rate.

Objective:The immunological effects of HCV-DNA vaccine with different adjuvants were detected by ELISPOT in mice.Methods:Female BALB/c mice were primed with naked HCV-DNA, HCV-DNA encapsulated by liposome DDAB/EPC or DC-Chol/DOPE, HCV-DNA mixed with Montanide ISA 720 or aluminum hydroxide, respectively, and boosted twice accordingly in a four-week interval. Cytokine production by splenocytes was assessed by ELISPOT.Results:In most cases, splenocytes from mice vaccinated with DDAB/EPC liposome produced more IFN-?. These splenocytes also have significant higher IL-2 production compared with the other groups. In expansion with NS5b, splenocytes from alum group have significance in IL-4 production compared with other groups. The profile of cytokine production revealed that the INF-? overwhelmed IL-4 in naked DNA, DDAB/EPC, and DC-Chol/DOPE groups while IL-4 surmounted IFN-? in alum and Montanide groups.Conclusion:Encapsulation with liposome DDAB/EPC has the strongest adjuvant effect in inducing Th1 dominated immunity. Alum and Montanide can convert the Th1 nature of DNA vaccine to Th2-biased immunity.
