Objective To provide an approach to research of peroxisome proliferator activated receptor (PPAR) ? 2 function, mouse PPAR? 2 (mPPAR? 2) gene was cloned and its transient expression in eukaryotic cells was carried out. Methods mPPAR? 2 mRNA from epididymis fat pad of Chinese Kunming mice was amplified by RT PCR and subcloned into plasmid pcDNA3 to generate the recombinant plasmid pcDNA3/mPPAR? 2 which was confirmed to contain the amplified target gene segments with fluorescence sequencing. The recombinant plasmid pcDNA3/mPPAR? 2 was used to transfect COS 7 with lipofectamine and the expressing product was detected with immune fluorescence assay and Western blot. Results The sequencing results for amplified target gene showed that the sequence of mPPAR? 2 from epididymis fat pad of Chinese Kunming mice is similar to that of mouse PPAR? 2 in Genbank, only at the site of 383 amino acid where Ser (AGC) substitutes Asn (AAC). pcDNA3/mPPAR? 2 was efficiently expressed in eukaryotic cells in vitro. Conclusion This work is the experimental basis for further researching on PPAR? 2 function.

Chinese Journal of Internal Medicine 2010;49(12):1020-1023
Objective To address the standard first-line management under the new diagnostic criteria in adult immune thrombocytopenia (ITP). Methods A retrospective analysis was conducted involving 178 adult ITP patients treated with high-dose dexamethasone or prednisone in Qilu Hospital from March 2004 to November 2009 using new diagnostic criteria. Results The median age was 41 years with a male/female ratio of 0. 73: 1. Among the 178 ITP patients, 87 were newly diagnosed, 30 persistent ITP, 58 chronic ITP, and 3 unable to follow up. The efficacy rates among 167 patients able to assess in the three groups were 77.4% ( 65/84 ), 64. 0% ( 16/25 ) and 62. 1% ( 36/58 ) respectively, and their complete remission (CR) rates were 57. 1% (48/84), 36. 0% (9/25) and 32. 8% (19/58). The efficacy rate and CR rate of the newly diagnosed ITP category were significantly higher than those of the chronic ITP category (x2 = 3. 917, P < 0. 05 ;x2 = 8. 186, P < 0. 01 ). The patients treated with high-dose dexamethasone or prednisone therapy had no significant differences in sex, age or blood platelet count before treatment.Moreover, the short or long term response rates and the CR rates between the two therapies had no statistically significant differences while the former had a shorter onset time ( F = 10. 34, P < 0. 01 ).Conclusions The study sets up a basis for the application of the recommended new definition and outcome criteria for adult ITP. Dexamethasone therapy is favored as first-line therapy.

Objective To study the impact of the high temperature and muggy weather on the people’s life and work. Methods The data of summer temperature and relative humidity (Jun-Aug) from 1971 to 2000 and that of 2006 were used and the characteristic of muggy weather and distribution in main cities, Chengdu, Guangyuan, Yibing, Suining and Dazhou in Sichuan basin were compared, the influence of the thermal environment on people comfort degree was evaluated by using temperature-humidity index. Results 177 high temperature days, 17 high temperature processes, 167 muggy weather days and 12 muggy processes were seen in 5 cities in Sichuan basin in the summer of 2006. The thermal environment of Chengdu and Dazhou mainly manifested the lighter heat, heat and lower comfort degree. At 2 p.m., the relative humidity weakened the comfort degree in Chengdu, but enhanced it in Dazhou. The duration of non-comfort degree in Dazhou was longer than that in Chengdu. Conclusion The relative humidity has a strong impact on people comfort degree and the combined use of temperature and relative humidity will be useful to evaluate the city thermal environment and people comfort degree.

Objective To investigate the percentage of CD4 + C125 +Tregs in peripheral blood of patients with sepsis and its effect on cell immunity so as to unravel the effect of immunomodulatory therapy on it. Method Fourty patients with sepsis in ICU were randomly (random number) divided into experimental group and control group . The patients of experimental group were treated with Ulinastatin and immunoregulation agent (Thymosin αl) as well. The blood specimens were collected just before treatment, 3 days and 8 days after treatment. The percentages of CD4 + CD25 + Tregs and lymphocyte subsets were detected by using FCM (flow cytometry), and TNF-α, IL-6 and IL-10 assayed by using ELISA, and APACHE Ⅱ scores were calculated. Results Before treatment, the percentage of CD4 + CD25 + Tregs increased, and the number of lymphocytes and the percentage of T lymphocytes decreased, especially the CD4 + T lymphocytes and CD4+/CD8+ decreased more markedly, and the levels of IL-6 and TNF-α increased. After treatment,the percentage of CD4+ CD25 + Tregs was decreased, the number of lymphocytes and CD4 +/CD8 + increased, and the levels of APACHE Ⅱ score, IL-6 and TNF-α decreased especially in the experimental group decreased more significantly (P < 0. 05). Conclusions The percentage of CD4 + CD25+ Tregs in peripheral blood can reflect the immune status of patients with sepsis and become a novel indicator to estimate the progress of sepsis, and the immunity and prognosis of patients. Treating the patients with Thymosin αl and Ulinastatin can raise their immunity, decrease the levels of IL-6, TNF-α and APACHE Ⅱ score and improve their prognosis.

Objective To investigate the expression and significance of platelet membrane glyco- proteins and antiplatelet antibody in patients with anaphylactoid purpura.Methods Forty-five patients with anaphylactoid purpura were divided into three groups according to their clinical manifestations,15 in dermal purpura group,18 in mixed group and 12 in nephritis group.The expression of CD62P,CD63 and CD41 in these 45 patients was detected by flow cytometry.The level of antiplatetlet antibody was analysed by ELISA with monoclonal antibody as the probe.Results The percentage of CD62P,CD63 and the level of an- tiplatelet antibody in patients in acute phase were significantly higher than those in regressive phase and those in normal control.Neither of the expression of CD62P,CD63 and CD41,nor the level of antiplatetlet antibody in nephritis group was significantly different from that in the mixed group.Compared with dermal purpura group,the percentage of CD62P was significantly higher in the nephritis group and mixed group. There was no significant difference in CD41 expression among all groups.Conclusion Abnormal humoral immunity exists in anaphylactoid purpura.The activation of platelet could be closely related to the progress of anaphylactoid purpura.CD62P and CD63 could be considered as an index for monitoring of symptoms, determination of prognosis and predicting the outcome in anaphylactoid purpura.
