Objective To evaluate the treatment effect of later course accelerated hyperfractionated radiotherapy with chemotherapy for stage Ⅲ and ⅣA nasopharyngeal carcinoma. Methods 116 patients with stage Ⅲand Ⅳ s nasopharyngeat carcinoma were randomly divided into three groups: the conventional fractionation radiotherapy(CFR, 38 cases), the concurrent radiochemotherapy group(CCRT, 39 cases) and the later course accelerated hyperfractionated radiotherapy combined with chemotherapy group (LCAF+CT, 39cases). CFR group was treated with 60Co γ rays and X rays. When the patients had received the dose of 36～38 Gy through composite faciocervical fields, changed into preauricular fields, the total dose was 70 ～75 Gy.And the total dose of cervical metastasis lymph nodes were 70～80 Gy. CCRT group was treated with DDP and 5-Fu. LCAF+CT group was treated with accelerated hyperfractionated radiotherapy. When the dose of composite faciocervical fields had reached 36～38 Gy, changed the fields and treated with accelerated hyperfractionated radiotherapy, 1.3 Gy/fraction, twice daily. The total dose was 69.8～75 Gy. And the chemotherapy drugs was similar to CCRT group. Results The positive response rate among LCAF+CT, CCRT and CFR groups were 94.9 %, 89.7 %, 76.3 % respectively. The complete response rate in the nasopharyn of LCAF+CT group was higher than CFR group(P ＜0.05). The local control rates of one, two and three year of three groups were 100 %, 97.4 %, 89.5 %, 94.9 %, 84.6 %, 68.4 % and 89.7 %, 74.4 %, 57.9 %respectively; and the survival rates of one, two and three year of three groups were 100 %, 92.3 %, 84.2 %;89.7 %, 84.6 %, 71.0 % and 79.5%, 76.9 %, 57.9 % respectively. There were obvious difference between LCAF+CT and CCRT groups in local control rate and survival rate. But there were no difference between LCAF+CT group and CCRTgroup, and also between CCRT group and CFR group. Conclusion The later course accelerated hyperfraetionated radiotherapy combined with chemotherapy can promote disappearance of primary lesion and improve the local control rate and survival rate of patients with stage Ⅲand ⅣA nasopharyngeal carcinoma.

This article summarized the research progress of sublingual collaterals from two aspects: the relationship between sublingual collaterals and diabetes mellitus and laboratory indexes, and the modern science and technology.

Aim To investigate whether ulinastatin has a beneficial effect on lipopolysaccharide( LPS) induced acute respiratory distress syndrome ( ARDS ) in rats, and to explore the possible underlying mechanisms. Methods Fifty-six Wistar rats were randomly as-signed into control group, model group( LPS 6,12,24 h groups), ulinastatin group(UTI 6,12,24 h groups), with 8 in each group. ARDS rat model was reproduced by intraperitoneal injection of LPS ( 10 mg · kg-1 ) , The rats in UTI groups were injected ulinastatin (20 000 u·kg-1), The rats in the control group re-ceived an equal volume of normal saline at the same time, rats in each group were sacrificed at 6,12,24 hours after LPS challenge. Plasma and lung tissue sam-ples were collected, Histopathological evaluation, lung wet/dry (W/D) ratio, Tumor necrosis factor-a(TNF-α) , Interleukin-18 ( IL-18 ) , surfactant protein A ( SPA) , malondialdehyde ( MDA ) , nitric oxide ( NO ) and superoxide dismutase( SOD) were analyzed. Immu-nohistochemical method was performed to detect the protein expression of p38MAPK and ERK. Western blot method was used to detect lung phosphorylated p38 MAPK ( p-p38 MAPK ) and pERK protein expres-sion changes. Result In the control groups, lung tis-sue showed a normal structure and clear pulmonary al-veoli under a light microscope. In the model group, ARDS characters such as extensive thickening of the alveolar wall, significant infiltration of inflammatory cells, demolished structure of pulmonary alveoli, and hemorrhage were found. In the all UTI treatment groups, these pathological changes in lung were markedly alleviated compared with those of LPS-in-duced ARDS group. Compared with control groups, lung W/D ratio, tumor necrosis factor-a ( TNF-α) , in-terleukin-18 ( IL-18 ) and surfactant protein A ( SPA ) in plasma ,and lung MDA,NO levels in lung homogenates in the LPS group were increased significantly, while the lung SOD levels in the LPS group were decreased. Compared with the LPS group, lung W/D ratio, TNF-aIL-18 and ( SPAin plasma , and lung MDA levels in lung homogenates in the UTI groups were decreased significantly, while the lung SOD levels in the UTI groups were increased. Immunohistochemistry showed that positive expressions of p38 MAPK and ERK in cy-toplasm and nucleus in the ulinastatin treatment groups were significantly lower than those in the model group. Western blot showed that compared with the control group, the p-p38MAPK and pERK protein expression in LPS group were significantly increased, and the uli-nastatin could inhibit the protein expressions compared with model group. Conclusion Ulinastatin can signifi-cantly ameliorate the lung injury induced by LPS in rats via the intervention of p38 MAPK and ERK signa-ling pathway and reducing inflammation and antioxidant effect.
