Third-order optical nonlinearities of two squarylium dyes with benzothiazole donor groups(BSQ1 and BSQ2)in chloroform solution are measured by a picosecond Z-scan technique at 532 *** is found that the two compounds show the saturation absorption and nonlinear self-focus refraction *** molecular second hyperpolarizabilities are calculated to be 7.46×10^(−31) esu and 5.01×10^(−30) esu for BSQ1 and BSQ2,*** large optical nonlinearities of squarylium dyes can be attributed to their rigid and intramolecular charge transfer *** difference inγvalues is attributed to the chloro group of benzene rings of BSQ2 and the one−photon resonance *** is found that the third-order nonlinear susceptibilities of two squarylium dyes are mainly determined by the real parts ofχ(3),and the large optical nonlinearities of studied squarylium dyes can be attributed to the nonlinear refraction.

AIM: To investigate the effect and possible mechanism of ulinastatin on renal ischemia-reperfusion injury in rats. METHODS: Male Sprague-Dawley rats were subjected to 45-min bilateral renal ischemia, treated with intravenously 12 500 U ulinastatin at 30 min prior to ischemia and at the beginning of reperfusion, compared with a nontreated group without ulinastatin and a sham-operation group without bilateral renal ischemia. After 0 h, 2 h, 6 h, 12 h, and 24 h of reperfusion, serum creatinine and blood urea nitrogen were measured for the assessment of renal function, renal sections were used for histologic grading of renal injury, for immunohistochemical localization of Bcl-2 and heat shock protein 70. Renal ultrastructure was observed through a transmission electron microscope. RESULTS: Ulinastatin significantly reduced the increase in blood urea nitrogen and creatinine produced by renal ischemia-reperfusion, suggesting an improvement in renal function. Ulinastatin reduced the histologic evidence of renal

Background Clinical outcome in patients with primary central nervous lymphoma （PCNSL） is variable and poorly predictable. This study investigated the association of clinical features and immune markers with prognosis of patients with PCNSL. Methods One hundred and fifteen newly diagnosed PCNSL patients at the study institution were considered eligible for this study. Clinical characteristics and biochemical assay data were collected. Immunohistochemical staining of Cyclin D3, Cyclin E, Foxpl, and LMO2 were performed. All cases were followed-up regularly. Results The common sites of involvement were frontal lobe （54.8%） and thalamus （16.5%）. Diffuse large B-cell lymphoma composed of 96.5% of the cases. The median overall survival was 22 （4-41） months, and the 5-year survival rate was 22.8%. Age 〉65 years, serum globulin 〉40 g/L, large size of tumor, lymphocyte count ≥1×10^9/L, and expression of Cyclin D3 and Cyclin E were associated with poor prognosis of PCNSL. Expressions of Foxpl, LMO2, and CD44 were not related to the survival. Expression of Cyclin E, large tumor size, and high serum globulin were independent prognostic factors for PCNSL. Conclusions PCNSL prognosis is relatively poor. Age, high tumor burden, higher lymphocyte count, expression of Cyclin D3, and Cyclin E are inferior prognostic factors for PCNSL.
