Objective To determine the levels of radiation-induced expressions of HIF-1α and Survivin in three human lymphoma cell lines with or without HIF-1a specific antagonist or HIF-1a siRNA transfection and to explore the possible mechanism of cell radioresistance.Methods Namalwa,Ramos,Raji cells were irradiated with X-rays with or without the combination of echinomycin (EC),a HIF-1α specific inhibitor,or transfection of HIF-1α siRNA.Then the expression levels of HIF-1α and Survivin proteins and mRNAs were determined by Western blot and real-time PCR,respectively.Results After irradiation,the expression level of HIF-1α protein was up-regulated at 10-20 h followed by up-regulation of survivin protein at 24 h (t =7.53-31.31,P ＜ 0.01 ) in three lymphoma cell lines.Radiation-induced up-expression of survivin protein was significantly reduced by either HIF-1α inhibition or EC treatment (t =7.21-32.81,P ＜0.01 ).However,radiation failed to induce up-erpression of survivin at both mRNA and protein levels after transfection with HIF-1α siRNA.Conclusion HIF-1α-Survivin pathway is activated in human lymphoma cells after radiation,which might be involved in the cell radioresistance.

Objective To investigate the relation of resistant index and function of transposited ovaries following radical hysterectomy in young women with early stage of cervical cancer.Methods A total of 22 young women(aged from 26 to 40 years old)with early stage of cervical cancer(FIGO Ⅰ a or Ⅱ a)were studied from Aug.1997 to Sep.2004 in the Affiliated Hospital of Inner Mongolia Medical Collage.Ovarian transposition was performed at the time of radical hysterectomy and pelvic lymphadenectomy in 12 cases who received postoperative radiotherapy;the rest 10 cases did not receive postoperative radiotherapy.Ovarian function was evaluated by serum FSH,LH,E_2 and B-ultrasonography in all of the cases.Results There was a statistically significant difference between the radiotherapy group and the non-radiotherapy group in serum E_2,FSH,LH levels and RI at the 24th month postoperatively.RI had a negative correlation with E_2 and positive correlation with FSH.Conclusion Ovarian transplantation can preserve the endocrine function of ovary for young women with cervical cancer.RI has a negative correlation with E_2 and positive correlation with FSH.RI is the important index of supervising ovarian function.Postoperative radiotherapy can influence RI and ovarian function.

Approaching an advantage in TCM and Chinese herbs, comparing the difference between them in many ways. TCM has macroscopic advantage and microcosmic disadvantage. Point out that only the theory of TCM be respected, the advantages of TCM can be kept.

Objective To explore the influence of Gui piperazine strange maleate on the high sensitive C-reactive protein(hs-CRP) and S100B in the serum of patients with acute cerebral infarction.Methods 90 patients with acute cerebral infarction were randomly divided into two groups,the control group(45 cases) and the treatment group (45 cases).The patients in the control group were treated through the conventional treatment,while the patients in the treatment group were treated plus Gui piperazine strange maleate.They were treated for fourteen days.The hs-CRP and S100B in the serum were detected before and after treatment.Results The total effective rates were 93.3％ in the treatment group and 84.4％ in the control group.There was a significant difference between two groups(x2 =4.0125,P ＜ 0.05).The hs-CRP and S100B were decreased after treatment in both groups (all P ＜ 0.05),and there was a significant difference between two groups after treatment (all P ＜ 0.05).Conclusion Gui piperazine strange maleate can improve acute cerebral infarction through mitigating inflammation.

Procalcitonin (PCT)is a biomarker of early bacterial infection,and it can reflect severity of infection,and regarded as a prognostic factor.Community acquired pneumonia(CAP) is the main mortality and morbidity cause of children under 5 years old.The diagnosis of CAP mainly depends on clinical symptoms and chest radioactivity and regular blood test,and absent of specific indications,and mainly depends on clinicians experiences.The diagnosis and prognosis values in children CAP have been proved by many clinical trials.This paper reviews the clinical value of PCT on children CAP.

[Objective] Via an empirical survey, this study is aimed to explore the imparting and mastering of Chinese cultural knowledge in China ’s present col ege English teaching, so as to offer some effective strategies for dealing with“Chinese culture aphasia”in current col ege English teaching in China. [Methods] Resorting to the research methodology of tests, questionnaires and interviews, it carries out an investigation of a number of col ege students and English teachers in Zhejiang Province into their mastering of Chinese cultural knowledge and its conveying in English as wel as the curriculum design of their col eges or departments. The relevant data derived from the research are analyzed qualitatively and quantitatively. [Results] The subjects al demonstrate the phenomenon of“Chinese culture aphasia”concerning both its comprehension and its English translation to varying degrees. Besides, cross-cultural commu-nication is twofold, so it is indispensible for learners to study simultaneously their native culture,which is a solid cornerstone and the crucial foundation for foreign language learning, but has been seriously deficient in col eges’curriculum design and students’textbooks; integrating Chinese as one of the com-pulsory courses and establishing corresponding examining and evaluating systems incorporating formative assessment and summative assessment, are sure to cope with“Chinese culture aphasia”in present col ege English teaching in China effectively. [Conclusion] The research and solution above are expected to shed light on teaching syl abus formulations and curriculum designs, enhance students ’humanistic quality and their communication capabilities in reality, and consequently popularize the excellent Chinese culture.

Objective To investigate the effect of recombinant human erythropoietin (rhEPO)injection on the nutritional quality and cardiac function in the patients with maintenance hemodialysis.Methods Sixty-two patients with chronic kidney failure were divided into two groups by random digits table:treatment group(46 patients, rhEPO injection therapy was given) and control group( 16 patients, without rhEPO injection therapy). The serum biochemical indexes and color sonography was respectively performed before and after the treatment. Results In treatment group, the cardiac function and the serum biochemical indexes improved obviously after 6 months' treatment (P ＜ 0.05 ). But there was no change in control group.Conclusion The treatment with rhEPO injection can effectively improve the nutritional quality and cardiac function in the patients with maintenance hemodialysis, and improve life quality.
