BACKGROUND:Qingre Huoxue Xiaozhong composition Ⅰ and Ⅱ made by ourselves are effective in treating bone fracture complicated by soft tissue injury.However,its mechanism is still unclear.OBJECTIVE:To observe the effect of Qingre Huoxue Xiaozhong composition on the levels of intedeukin 1β(IL-1β) and interleukin 6(IL-6) in serum of patients with closed bone injury-induced soft tissue injury.DESIGN:Randomized controlled observation.SETTING:Wards of the Department of Traditional Chinese Medicine,the 401 Hospital of Chinese PLA.PARTICIPANTS: Eighty-eight inpatients with bone fracture at early and moderate stages accompanied by soft tissue injury were chosen as volunteers to be studied in the Department of Traditional Chinese Medicine,the 401 Hospital of Chinese PLA between February 2000 and February 2002.The involved inpatients were assigned into 2 groups according to the table of random digit:Oingre Huoxue Xiaozhong composition Ⅰ + Ⅱ group (n=45) and Qingre Huoxue Xiaozhong composition Ⅱ group (n=43).Oingre Huoxue Xiaozhong composition Ⅰ was for internal administration,and Qingre Huoxue Xiaozhong composition Ⅱ was for external fumigation.METHODS:①Treatment of bone injury:Both caltrate D pellets and pills for strengthening bone joints were used in two groups.②Treatment of soft tissue injury: In the Qingre Huoxue Xiaozhong composition Ⅰ+ Ⅱ group,Qingre Huoxue Xiaozhong composition Ⅰ was decocted.Each decoction was 450 mL,and was packed into 3 pouches, 150 mL/pouch,three times a day;Qingre Huoxue Xiaozhong composition Ⅱ was decocted.Each decoction was 600 mL,and was packedinto 4 Douches,150 mL/pouch.Four pouches of Qingre Huoxue Xiaozhong composition Ⅱ was diluted by 2 000 mL water,then heated and used for fume-washing, twice a day, 20 to 30 minutes once. Four pouches could be used for fume-washing for 2 days successively. In the Oingre Huoxue Xiaozhong compositionⅡgroup, only Oingre Huoxue Xiaozhong composition Ⅱ was used to fume-wash the lesioned region.The concrete method was the same as that in the Qingre Huoxue Xiaozhong composition Ⅰ+Ⅱ group.In each group, ten days were set as one course of treatment,and totally, there are 2 courses of treatment.IL-1β and IL-6 levels in serum of patients were detected by with ELISA kit before.one and two courses after treatment, and compared separately.MAIN OUTCOME MEASURES: Levels of IL-1β and IL-6 in serum of patients in two groups before, one and two courses after treatment.RESULTS: In the eingre Huoxue Xiaozhong composition Ⅰ+Ⅱ group,the level of IL-1β and IL-6 was respectively significantly lower after 2 courses of treatment as compared with the previous one and one course after treatment (P＜0.05-0.01), also at the same time point in compared with the Qingre Huoxue Xiaozhong composition Ⅱ group (P＜0.05).In addition, in the Oingre Huoxue Xiaozhong composition Ⅰ+Ⅱ group,the level of IL-1β and IL-6 was respectively significantly decreased after one course of treatment as compared with before treatment (P＜0.05). In the Oingre Huoxue Xiaozhong composition Ⅱ group,after 2 courses of treatment,the level of IL-1β was significantly decreased as compared with before treatment, and the level of IL-β was also significantly decreased as compared with before treatment and after one course of treatment (P＜0.05).CONCLUSION: Qingre Huoxue Xiaozhong composition Ⅰ+Ⅱ can be used to treat bone fracture accompanied by soft tissue injury by inhibiting the levels of IL-1β and IL-6. The effect of the combination of Oingre Huoxue Xiaozhong composition Ⅰ and Ⅱ is superior to that of each alone.

OBJECTIVE To investigate spectrum and drug resistance of No-Pseudomonas aeruginosa,to provide the basis for proper use of antibiotics and prevent patients from hospital acquired infection.METHODS API staph analysis system and the K-B agar diffusion test according to NCCLS were used to identify 357 strains of No-Pseudomonas aeruginosa and to performe drug sensitivity test.RESULTS From 2004 to 2008,357 strains of No-Pseudomonas aeruginosa were isolated.There are 233 Stenotrophomonas maltophilia strains(65.27%,233/357),55 Burkholderia cepacia strains(15.41%,55/357).Sputum was the main sourse of No-P.aeruginosa(88.52%,316/357).The isolation rate of No-P.aeruginosa was the highest in intensive care units(38.10%,136/357),the next was department of respiratorymedicine(23.53%,84/357).The results of drug susceptibility test showed that the resistance rate of No-P.aeruginosa to most drugs were higher,only the resistance rates of S.maltophilia to minocycline,gatifloxacin and levofloxacin were lower,(3.26%,20.55% and 20.83% respectively),The resistance rates of B.cepacia to meropenem,piperacillin/tazobactam and Imipenem were lower,being 29.17%,33.33% and 39.62% respectively.CONCLUSIONS The most common strains is S.maltophilia and Burkholderia cepacia,the most common site of infection is lower respiratory tract,Most strains of S.maltophilia are isolated from ICU and department of respiratory diseases.The result of drug sensitive test showed that there were high rates of multiple drug resistance in No-P.aeruginosa and treatment of No-P.aeruginosa infection should be based on the results of the drug susceptibility test.

AimTo find out the comprehensive strength and trends in scientific research area,and to provide foundation for decision-making on pushing the paediatric research forward,we reviewed the achievements of the scientific papers publication and the professional background of the authors between 2001 and 2010. Methods We extracted data and described the distribution characteristics of the paper publication amount,degree in the 10 years,as well as age,construction of professional and technical title,the education qualification of the authors. Moreover,we statistically analyzed the variability of the publication conditions within statistical source journals among the authors with different technical title.ResultsThe amount of paper publication increased anually in the 10 years,but with few published in statistical source journals,and the core authors group have not formed yet.Meanwhile,the general internal medicine maintained the dominant propotion.Authors aged 30 -50 years old,with middle technical title and with bachelor degree published the majority of the papers.The propotion of the papers published in statistical source journals and in the Zhonghua series medical journals were significantly higher in authors with master degree and above.ConclusionsIn order to construct a stable core authors group and increase the amount of the paper publication,we should continue to encourage those author groups with high output rate and make greater support on the potential authors.Furthermore,we must take more effort on impoving publication quality in the future.

AIM: To study the influence of PD098059 on the rat platelet aggregation rate and the phosphorylation of ERK1/2 induced by the different agonists, and to observe the effects of phosphorylation of ERK1/2 on the platelet aggregation. METHODS: The maximal aggregation rate (MAR) was measured by nephelometry. The inhibitory rate of PD098059 and the appearing time of MAR were also observed. ERK1/2 phosphorylation was detected by Western blot. RESULTS: The phosphorylation of ERK1/2 was detected during aggregation induced by thrombin and ADP. PD098059 inhibited the MAR and phosphorylation of ERK1/2. Effects of PD098059 were different on the aggregation induced by thrombin and ADP. CONCLUSIONS: The phosphorylation of ERK1/2 is one of the cellular signal transduction mechanisms of platelets aggregation. Phosphorylation of ERK1/2 plays different roles during the platelet aggregation induced by thrombin and ADP. [
