0.05).Conclusion Gatifloxation is safe and efficient in the treatment of community acquired pneomonia.

Objective To evaluate the morphological and signal intensity changes after anterior cruciate ligament reconstruction , and to analyze the correlations between MRI evaluation and clinical examination .Methods Totally 34 patients who underwent anterior cruciate liga-ment reconstruction in our hospital from July 2013 to June 2015 were given MRI examination .The morphology ,orientation and signal intensity of the anterior cruciate ligament grafts were evaluated on axial ,sagittal and coronal images .The grafts were assessed with Rak method ,and the clinical assessment was adopted with physical assessment method ,including drawer test ,axial shift test and Lachman test .The correlations be-tween MRI evaluation and clinical examination results were further analyzed by SPSS 16.0.Results After anterior cruciate ligament recon-struction,79%of the graft were visualized as a smoothly continuous low signal (well-defined type),15%of the graft showed increased signal intensity with only a small part of low signal bands ( intermediate type ) ,and 6% of the grafts showed remarkably increased signal intensity (indiscernible type).A statistically significant correlation was identified in MRI evaluation and clinical examination results (P<0.05). Spearman’ s correlation coefficient was 0.747 2 which indicating significantly positive correlation .Conclusion Magnetic resonance imaging is a noninvasive high-resolution imaging technology and it is an effective tool for evaluating anterior cruciate ligament reconstruction .

Objective To evaluate the effect of the expression of P-glycoprotein (P-gp) in tumor tissue on analgesic efficacy of morphine and buprenorphine in advanced cancer patients with pain. Methods One hundred and fifty advanced cancer patients with pain aged 51-64 yr weighing 54-65 kg were included in this study. The expression of P-gp was negative in the tumor tissue in 50 patients (group M1 and B1, n = 25 each) and positive in 100 patients (group M2 ,M3 ,and B2 ,B3, n =25 each). The PCA regimen for the 6 groups were listed in the table .Pain was assessed with VAS scores (0 = no pain, 10 = worst pain) and venous blood samples were taken for determination of blood morphine/buprenorphine concentrations at 4, 12, 24 and 48 h of PCIA. Results The six groups were comparable with respect to age, body weight, M/F sex ratio, types of cancer, baseline pain level and education. The analgesic efficacy of morphine and buprenorphine was better ( VAS scores were significantly lower)in P-gp expression negative patients (group M1 and B1 ) than in P-gp expression positive patients (group M2 and B2 ). Higher doses of morphine and buprenorphine provided better analgesic efficacy in P-gp expression positive patients in group M3 and B3 than in group M2 and B2. Plasma morphine and buprenorphine concentrations were comparable between group M1 , B1 and M2, B2 and were significantly higher in group M3 and B3 at each time point. Conclusion Positive P-gp expression in the tumor tissue can decrease the analgesic efficacy of morphine and buprenorphine in advanced cancer patients with pain.

Objective To determine the effect of age,body figure and risk framing in making treatment decision for female patients with breast cancer.Methods Two groups of healthy female:one group of 60 female ages 18-24 from undergraduate student and the other group of 60 female ages 35-60 from the university community.Healthy women imagined that they had been diagnosed with breast cancer and received information regarding lumpectomy versus mastectomy and recurrence rates.Participants indicated whether they would choose lumpectomy or mastectomy and reasons.Results The different concern levels of body appearance between younger and older women influences treatment selection of lumpectomy versus mastectomy.Facing the risk information,older women were unlikely to select the breast conserving operation.Conclusions The factors of age and the attention to body figure would effect the choice of breast conserving operation or mastectomy.Risk information on the selection of treatment would not affected directly,but the effects of risk information on younger and older female is different.Nurses should provide the age-appropriate information who recently have been diagnosed with breast cancer regarding treatment alternatives to ensure their active participation in the decision-making process,female who have different levels of investment in body figure also may have different concerns about treatment,and should be alert on empathetic of such concerns.

Background and Purpose:Kaposi's sarcoma(KS) cases occurring in renal allograph recipients was considered to be due to long-term immunosuppressive therapy.But the exact carcinogenetic process has not been elucidated so far.The lesions could not be distinguished from other KS types by histopathological study.Endemic KS cases seemed to be more common in Xinjiang,especially in the Uygur ethnic group,and their relation to other types of KS was investigated in three cases by histopathology and immunohistochemistry for the present study.Methods:Biopsy specimens from three cases of renal tronsplantation related KS,including two Uygur and one Han patients,were obtained from this hospital(No.474 hospital of PLA).Formalin-fixed and paraffin embedded blocks were cut for routine HE and immunohistochemical staining to study respectively.Monoantibodies of CD34,Ⅷ-factor,Vimentin,actin and FN were detected by S-P techniques for immunohistochemistry.Results:Histopathologically,the typical histology of traditional KS was found in almost all the specimens of the three patients.In the early stage of the disease,there are only a few vessel fissures with irregular dilation and clustering obese(epithelioid)cells.In the middle stage,the changes are wider in scope with proliferation of spindle cells,in the form of beams and weaves.The proliferating vessels are dilated and hyperemic around the lesion.In the late stage,the spindle cells proliferation are markedly atypical,and karyokinesis is increased.Immunohistochemistry showed CD34 to be more strongly positive,Ⅷ-Factor(+),Vimentin(+) showed a weak reation;while actin(-),FN(-) were negative.Conclusions:Renal transplantation related KS is not essentially different from other types of KS both in histopathohogy and immunohistochemical characters which may reflect that they have a similar etiopathogenetic procession.However,the distinctive distribution of morbidity among different ethnic groups or districts strongly suggested that the genetic background plays a critical role on KS carcinogenesis.

AIM　To study the effects of dexamethasone on expressing monocyte chemoattractant protein-1(MCP-1 ) mRNA in the rats with pulmonary fibrosis, elaborate the molecular mechanism of dexamethasone (Dxs) in pulmonary fibrosis therapy. METHODS　The model of pulmonary fibrosis was established by instilling bleomycin intratracheally. After treating with Dxsip, the levels of MCP-1 mRNA were determined by RT-PCR. The histological changes were observed and the numbers of inflammatory cells were counted in optical microscopy field. RESULTS　The accumulation of inflammatory cells decreased markedly, and the symptom of pulmonary fibrosis was alleviated. Furthermore, Dxs evidently inhibited the expression of MCP-1 mRNA in lung tissues with pulmonary fibrosis. CONCLUSION　The molecular mechanism of Dxs in pulmonary fibrosis therapy was associated with inhibiting the expression of MCP-1 mRNA.
