Critical Discourse Analysis ( CDA) attempts to uncover the inequality in social reality and the way language presents power and ideology through the analysis of language features. Systemic functional linguistics ( SFL) focuses on the dialectical relationship between language and society and has been considered an important approach and theoretical basis to CDA. Doctors in Chinese medical clinic follow the Four Diagnostic Methods, within which the inquiry diagnosis strongly shows the fact that doctor and patient clash over the ideology and strug-gle for the power via language. The study carries out CDA on doctor-patient discourse in Chinese medical clinic within the theoretical framework of SFL from four aspects including nominalization, classification, transitivity and mood, which verifies that the language is the product of asymmetric power between doctor and patient. It is hoped that the paper would provide insight into CDA on doctor-patient discourse and would be of theoretical meaning.

BACKGROUND:A surgery can relieve the increased intracranial pressure, brain tissue edema, and brain stem compression in patients with massive cerebral infarction, and reduce the risk of serious complications, provide more time for medical treatment, and decrease the mortality and disability rate.
OBJECTIVE:To investigate the clinical value of decompressive craniectomy plus temporal muscle sticking therapy of cerebral infarction.
METHODS:A retrospective analysis was performed among the clinical data of 37 cerebral infarction patients, including 24 males and 13 females, they aged 10-55 years old. After decompressive craniectomy plus temporal muscle sticking therapy, the involved patients were fol owed up. The prognosis was evaluated according to the Glasgow Outcome Scale, as excel ent, good, moderate, none, and poor.
RESULTS AND CONCLUSION:At 6 months of fol ow-up, the total efficiency of surgical treatment in 37 patients was up to 89%, including excel ent in 5 cases (14%), good in 15 cases (41%), moderate in 13 cases (35%), none in 4 cases (11%). No cases exhibited aggravation. Thirty-one patients with cerebral infarction were detected by cranial CT scans, among them 19 patients exhibited significantly reduced infarct size, and 12 patients who had self-care ability were found to restore the cerebral cortex activity. During the 1-year fol ow-up, 31 patients completed the fol ow-up, the remaining 6 cases were lost due to contact failure. Twenty-three cases achieved satisfactory long-term results, and returned to normal work and simple labor, two cases occurred contralateral cerebral infarction and became sicker. Decompressive craniectomy plus temporal muscle sticking therapy is an effective treatment for the majority of cerebral infarction.

Objective To investigate feasibility, efficacy and safety of holmium laser lithotripsy under ureteroscopy to treat ureteral calculi. Methods Clinical data of 162 patients with ureteral calculi treated by holmium laser lithotripsy under ureteroscopy in our hospital from June 2006 to October 2009 were reviewed retrospectively. Stone-broken rate,lithagogue rate and complication were observed. Results The overall rate of successful fragmentation for all levels of ureteral calculi in a single procedure achieved 96. 30% (156/162). The success rates of fragmentation for the upper and mid-lower segment of ureteral calculi was 86.11% (31/36)and 99.21% (125/126),respectively. In 156 patients, the postoperative follow-up of 2- 4 weeks revealed that the stone free rate was 98.08 % (153/156). The mean operative time was (36 ± 11 )mains ( ranged from 15 to 90) and hospital stay ranged from 1 to 10 days. Conclusion Holmium laser lithotripsy under ureteroscopy is feasible,high effective and safe for the treatment of ureteral calculi, especially for those with middle or lower levels ureteral calculi.

Thrombospondin-1 is known as its anti-angjogenic and proapoptotic activities in oncogenesis. In current research, it has a intimate relationship with taxol resistance. Sensitivity of tumor cells to taxol will descend when the expression:of TSP1 is downregulated,and TSP1 downregulation is mediated by a new gene of taxol-resistance gene 1, the discovery provids a new trend to solve taxol resistance.
