Aim: To investigate the expression and the regulation of Bim protein in leukemic cell of patient with chronic myelognous leukemia(CML). Methods: The primary leukemic cells from the peripheral blood or bone marrow of patients with CML were isolated and cultured. The expression of Bim in the present or absence of ima-tinib(BCR/ABL inhibitor) was detected by the Western blotting, immunohistochemical analysis and real-time quantitative PCR. Results: Bim was consecutively expressed in normal bone marrow, but significantly decreased in the bone marrow of patients with CML( P < 0. 05). Imatinib significantly enhanced Bim mRNA transcription and expression in the manner of time- and dose-dependence. Moreover, there was reverse correlation between Bim protein level and the percent of leukemic cell in bone marrow( r =0. 849 1, P <0. 05). Conclusion: Bim is the Bcl-2 family pro-apoptitic factor. The decreased expression of Bim could be vital in the CML, Bim protein up-expression following the suppression of BCR/ABL might be of importance in investigation of the Bim-induced ap-optosis for potential clinical therapy.

Objective The current study was designed to observe the efficacy and toxicity of recombinant human interleukin-11 (rhIL-11) in prevention and treatment of chemotherapy-induced thrombocytopenia in patients with acute myelogenous leukemia. Methods The total of 21 acute myelogenous leukemia patients with chemotherapy-induced thrombocytopenia(

Objective To study the clinical curative effect of the recombinant human granulocyte-macro-phage colony-stimulating factor ( rhGM -CSF) joint R-CHOP regimen in the treatment of diffuse large B cell lymphoma (DLBCL).Methods 72 hospitalized patients with DLBCL were chosen from January 2014 to January 2015.The patients were randomly divided into joint CHOP rituxan group ( R-CHOP group,36 cases) and the joint treatment group (36 cases) .The R-CHOP group was treated by R-CHOP regimen,the joint group was given rhGM-CSF on the basis of R-CHOP treatment.Before chemotherapy and 15 days,1 month,3 months after chemotherapy, the peripheral blood was collected,and the monocytes were separated,flow cytometry was used to count HLA-DR, CD197 marked M1 cells and CD68,CDl63 marked M2 cells.4 months after chemotherapy,the curative effect was evaluated.Results 4 months after treatment,the ORR of joint group (91.67%) was significantly higher than that of R-CHOP group (75.00%),and the difference was statistically significant (χ2 =4.372,P<0.05).After treatment, the adverse reactions of joint group,the liver function injuryⅠ-Ⅱlevel 8.33%,Ⅲ-Ⅳlevel 0.00%;White blood cells reduceⅠ-Ⅱlevel 25.00%,Ⅲ-Ⅳ level 5.56%;Thrombocytopenia Ⅰ-Ⅱ level 19.44%,Ⅲ-Ⅳ level;8.33%;Nausea and vomitingⅠ-Ⅱ level 8.33%,Ⅲ-Ⅳ level 0.00%.The adverse reactions after treatment of R-CHOP group,the liver function injury Ⅰ-Ⅱ level 13.89%,grade Ⅲ-Ⅳ2.78%;White blood cells reduceⅠ-Ⅱlevel 36.11%,Ⅲ-Ⅳlevel 11.11%;ThrombocytopeniaⅠ-Ⅱlevel 33.33%,Ⅲ-Ⅳlevel 2.78%;Nau-sea and vomitingⅠ-Ⅱ level 13.89%,Ⅲ-Ⅳ level 0.00%.The increased ratio of TAM quantity in combined treatment group (63.89%) was significantly more than R-CHOP group (38.89%),the difference was statistically significant (χ2 =7.938,P <0.05).In joint group,the positive expression rates of CD68 (46.11%),IL -6 (44.44%),IL-8 (58.33%) were significantly higher than those of R-CHOP group[CD68 (13.89%),IL-6 (19.44%),IL-8 (38.89%)],the differences were statistically significant (χ2 =3.278,3.278,4.489,all P<0.05).Conclusion R-CHOP joint rhGM -CSF has better curative effect than R-CHOP plan and less adverse reaction,and under the induction of rhGM -CSF,mononuclear cells can develop into M1 macrophages,in DLBCL microenvironment,to induce TAM to M1 M2 type in reverse polarization,improve the microenvironment of DLBCL and provide chance for cure of DLBCL.

Objective To analyze impact of extreme low temperature and rainy weather on epidemic of infectious diseases in Nanning City and to provide a scientific basis of preventing and controlling infectious diseases caused by extreme weather events . Methods The data about incidences of respiratory tract infectious diseases ,enteric infectious diseases ,vector-borne infectious disea-ses ,natural foci of diseases from December 2007 to March 2008 and from December 2011 to April 2012 were analyzed by χ2 test . Results The incidence of respiratory tract infectious diseases were influenced greatest by extreme low temperature and rainy weather than other infectious diseases .The incidence of infectious diseases showed hysteresis effect of climate .Incidences of respira-tory tract infectious diseases ,enteric infectious diseases ,vector-borne infectious diseases ,natural foci of diseases during extreme low temperature and rainy weather were significantly higher than that during the same period of other years .And incidences of these were highest during the first 3 months of 2012 .Conclusion Extreme low temperature and rainy weather in Nanning City have im-pact on the incidence of infectious diseases ,which increased the incidence of infectious diseases at different degree .Ventilation and exposure clothes and quilts in the sun are not feasible during low temperature and rainy weather ,therefore health habits should be maximum emphasized when encountering extreme climate events .

ObjectiveTo analyze the effect and possible mechanism of the synergistic treatment with Qingjin Huazhuo Formula （清金化浊方， QHF） on the occurrence of thrombotic events in hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease （AECOPD） and phlegm heat stasis obstructing in the lung syndrome. MethodsIn a retrospective cohort study， 305 AECOPD inpatients with the syndrome of phlegm heat stasis obstructing in the lung were included. According to whether using QHF （the course of treatment ≥ 7 days）， they were divided into the exposure group （193 cases） and the non-exposure group （112 cases）. Totally， 109 pairs of cases were obtained by 1∶1 propensity score matching （PSM）. After matching， the occurrence of thrombotic events during hospitalization， the remission of main symptoms or signs （including cough， expectoration， wheezing， cyanosis） after 10 days （±3 days） of treatment， and the difference of the indicators including D-dimer， percentage of neutrophils （NEUT%）， C-reactive protein （CRP）， arterial partial pressure of oxygen （PaO₂）， and arterial partial pressure of carbon dioxide （PaCO₂） before treatment and after 10 days （±3 days） of treatment during the first auxiliary examination. ResultsAfter matching， the incidence of thrombotic events during hospitalization in the exposure group （5 cases， 4.59%） were lower than that of the non-exposure group （15 cases， 13.76%， P＜0.05）. The exposure factor that taking QHF for 7 days or above was a protective factor for thrombotic events in AECOPD hospitalized patients with phlegm heat stasis obstructing in the lung syndrome （RR = 0.333， 95% CI 0.126 to 0.885）. The remission rates of cough （100/109， 91.74%）， expectoration （103/109， 94.50%）， wheezing （102/109， 93.58%）， and cyanosis （97/109， 88.99%） in the exposure group were significantly higher than those in the non-exposure group （90/109， 82.57%； 94/109， 86.24%； 89/109， 81.65%； 86/109， 78.90%） after treatment （P＜0.05）. After treatment， the levels of D-dimer， NEUT%， CRP and PaCO₂ in both groups significantly decreased （all P＜0.05）， and the level of PaO₂ significantly increased （P＜0.05）. The difference of the levels of D-dimer， NEUT% and PaO₂ in the exposure group before and after treatment were larger than those in the non-exposure group （P＜0.05）， while the pre-post difference of CRP and PaCO₂ were not significantly different between the two groups （P＞0.05）. ConclusionThe synergistic treatment with QHF can effectively reduce the occurrence of thrombotic events， alleviate the clinical symptoms or signs such as cough， expectoration， wheezing， and cyanosis， and can improve lung function in hospita-lized patients with AECOPD and phlegm heat stasis obstructing in the lung syndrome. Its mechanism may be related to improving blood coagulation and inflammatory status.
