Objective:To study the effect and influence factor analysis of DLBCL patient with early stage who receive radiotherapy after chemotherapy.Methods: 374 cases of patients with DLBCL was selected from January 2010 to December 2015 in our hospital. By random number table method, the patients were divided into CHOP group (n=104), R-CHOP+RT group (n=93), R-CHOP group (n=80), CHOP+RT group (n=97). CHOP chemotherapy was given to all patients, 180 patients received radiotherapy after chemotherapy, and 169 patients received rituximab. Survival rates were compared between the 4 groups.Results: The survival rate of R-CHOP group in 12 months, 24 months, 50 months and 100 months were lower than R-CHOP+RT group, but the difference was not statistically significant in twelfth months(x2=2.02,P>0.05). The differences of 24 months, 50 months and 100 months were statistically significant (x2=4.08,x2=4.03,x2=8.79;P<0.05); The survival rate of CHOP group was 12 months and 24 months was higher than CHOP+RT group which the difference was not statistically significant (x2=1.05,x2=0.22;P>0.05); The survival rate of CHOP group in 50 months and 100th months was lower than CHOP+RT, but the difference was no significant difference (x2=1.62,x2=0.03;P>0.05). Smoking index, whether the use of rituximab, the age associated with the survival of patients, the difference was statistically significant.Conclusion: Early DLBCL patients with R-CHOP and radiotherapy combined treatment can be effective in patients with survival, while the use of rituximab chemotherapy, in addition to smoking on the prognosis of patients with serious adverse effects.

OBJECTIVE:To observe the effectiveness and safety of different doses of rosuvastatin in the treatment of acute ce-rebral infarction. METHODS:Totally 120 patients with acute cerebral infarction were selected from Weifang Yidu Central Hospital during Jan. 2014-Dec. 2015,and then divided into observation group and control group according to admission order,with 60 cas-es in each group. Both groups received routine treatment as Shuxuening injection 10 mL,iv,1-2 times a day(or 20 mL added into 5% Glucose injection 250-500 mL,ivgtt,qd)+Aspirin enteric-coated tablets 0.1 g,po,qd. Control group and observation group were additionally given Rosuvastatin calcium tablets 10 mg and 20 mg,po,qd(after supper). Both groups were treated for 30 d. The levels of serum inflammatory factors(hs-CRP,TNF-α,IL-6),blood lipid indexes(TC,TG,LDL-C),neurological function and activity of daily life score were observed in 2 groups before and after treatment. The clinical efficacy and occurrence of ADR were recorded. RESULTS:Before treatment,there was no statistical significance in the levels of hs-CRP,TNF-α,IL-6,TC,TG and LDL-C,NIHSS scores and Barthel index (BI) scores between 2 groups (P>0.05). After treatment,the levels of hs-CRP, TNF-α,IL-6,TC,TG and LDL-C,NIHSS scores in 2 groups were decreased significantly,while BI scores were decreased signifi-cantly,observation group were significantly better than those of control group,with statistical significance (P<0.05). Total re-sponse rate of observation group (93.33%) was significantly higher than that of control group (86.67%),with statistical signifi-cance (P<0.05). The incidence of ADR in observation group (23.33%) was significantly higher than control group (6.67%), with statistical significance(P<0.05). CONCLUSIONS:Rosuvastatin can significantly reduce the inflammatory reaction and blood lipid level of patients with acute cerebral infarction,inhibit the formation of atherosclerotic plaque and improve prognosis. The large dose of rosuvastatin have better efficacy for acute cerebral infarction and can significantly improve the symptom of neurologi-cal deficits and daily living ability of patients.

Aim To investigate the effects of leptin on ?1(Ⅰ) collagen mRNA expression and protein production, and the roles of Janus kinase/signal transducers and activators transcription(JAK/STAT) signaling transduction pathway in increased ?1(Ⅰ) collagen mRNA expression stimulated by leptin in activated hepatic stellate cells(HSCs).Methods Firstly, ?1(Ⅰ) collagen mRNA expression and protein production as well as JAK1 and STAT3 phosphorylation induced by leptin at different doses in a human HSC cell line, LX-2 were determined by RT-PCR, ELISA, and Western-blot.Secondly, the effects of JAK1 inhibitor AG490 on JAK1 phosphorylation and ?1(Ⅰ) collagen mRNA expression stimulated by leptin were detected by Western blot and RT-PCR. Thirdly, the roles of AG490 and transfection with STAT3 antisense oligonucleotide(STAT3-ASON) in STAT3 phosphorylation after leptin were detected by Western blot. Finally, the effect of transfection with STAT3-ASON on ?1(Ⅰ) collagen mRNA expression after leptin was measured by RT-PCR.Results Leptin increased ?1(Ⅰ) collagen mRNA expression and protein production in a dose-dependent manner in LX-2, reaching a maximal level at 80 ?g?L-1 leptin. In addition, phosphorylation of JAK1 and STAT3 after leptin exhibited a time-dependent effect. Besides, JAK1 inhibitor AG490 completely blocked JAK1 and STAT3 phosphorylation and increased in ?1(Ⅰ) collagen gene expression after leptin in LX-2. Transfection with STAT3-ASON blocked STAT3 phosphorylation and increased ?1(Ⅰ) collagen mRNA by leptin in LX-2.Conclusion Leptin had a direct action on liver fibrogenesis by stimulating ?1(Ⅰ) collagen mRNA expression and protein production in activated HSC, and JAK/STAT signaling transduction pathway was involved in the process. JAK1 inhibitor AG490 and transfection with STAT3-ASON blocked the transduction pathway effectively in LX-2. Leptin may be an important factor in the development of hepatic fibrosis. Activated JAK1 and STAT3 signaling in human HSC line provided a novel molecular target for therapeutic intervention of liver fibrosis.
