Objective To develop a new specie-specific nest PCR to diagnose the invasive aspergillosis and to estimate the detection of circulating galactomannan by sandwich ELISA in immunocompromised patients. Methods (1) To develop an animal model of IA and collect the whole blood and tissues from the animal model. To extract the DNA from the whole blood and perform nest PCR of the DNA ;To perform the nest PCR of the clinical blood samples from immunocompromised patients (2)To detect the circulating galactomannan from the immunocompromised patients samples by use of sandwich ELISA. Results (1) In animal model, the positive rate of nest PCR and blood culture were 77.8% and 16.7%;The sensitivity and specificity of nest PCR in animal model with invasive aspergillosis are 77.8% and 100%;(2) The sensitivity and specificity of nest PCR in immunocompromised patient were 100% and 83.3%;The sensitivity and specificity of sandwich ELISA in immunocompromised patient were 55.6% and 88.2%. Conclusions The positive rate of the nest PCR was higher than that of the blood culture in animal model. The nest PCR method has good sensitivity and specificity in both animal model and patients. It will be a promising method in diagnosis of invasive aspergillosis. The ELISA method will be helpful in diagnosis of invasive aspergillosis.

ObjectiveTo investigate the influence of nateglinide treatment of newly diagnosed patients with type 2 diabetes on the state of inflammatory response. MethodsThe clinical data of 74 newly diagnosed patients with type 2 diabetes were retrospectively reviewed,and treated with nateglinide,before and after treatment,the fasting blood glucose (FBG), postprandial blood glucose 0.5h ( 0.5 hPG), 1 h postprandial blood glucose ( 1 hPG) ,2h postprandial blood glucose(2hPG) ,fasting insulin(FINS) ,0.5h postprandial insulin(0. 5hINS) ,postprandial 1h insulin( 1 bINS),2h postprandial insulin(2hINS),interleulin-2(IL-2) and C-reactive protein(CRP) levels were observed. ResultsAfter treatment,the FBG,0. 5hPG, 1hPG,2hPG, FINS,0. 5hINS, 1hINS,2hINS, IL-2 and CRP of patients were ( 8.0 ± 1.5) mmol/L,(12.0±1.8)mmol/L,(10.2 ± 1.3) mmol/L,(10.5 ±1.2) mmol/L,(168.2 ±11.5) pmol/L,(213.5±23.5) pmol/L,(197.0 ±21.5) pmol/L,(189.5 ±12.0) pmol/L,(14.0 ±1.5) μg/L, (13.5 ±1.5) mg/L,compared with( 10. 5 ± 1.0) mmol/L, ( 14. 5 ± 1.5) mmol/L, ( 12. 5 ± 1.4) mmol/L, ( 11.6 ±2.0) mmol/L,(180.7 ±12.0) pmol/L,(229.8 ±26.0) pmol/L,(218.5 ±23.0) pmol/L, (197.0± 14.5) pmol/L,(12.5 ±2.0) μg/L, (22.8 ±2.0) mg/L before treatment decreased significantly(t =11. 9293,9. 1785,10. 3561,4. 1115,6. 4696,4.0009,5. 8744,3. 4279,5. 2307,32.0006, all P ＜0. 05). There was no serious adverse events in treatment process. ConclusionNateglinide treatment of newly diagnosed patients with type 2 diabetes could significantly improve the patient's inflammatory response state,and there was no serious adverse events in treatment process.

Objective To study the effective method of improving the diagnosis and treatment of blunt liver injury.Methods The clinical data of 135 cases with blunt liver injury hospitalized in Daxing District People' s Hospital from January 2000 to October 2010 were reviewed retrospectively.Results By standard grading of American Society of Trauma Surgery (AAST) in 1994,36 cases were grade Ⅰ,42 cases gradeⅡ,33 cases gradeⅢ,14 cases grade Ⅳ,10 cases gradeⅤ.Fifty-one cases were treated by non-operative therapy,among which 42 cases were crued,9 cases underwent operative surgery.Ninety-three cases were treated by operative therapy,seven cases died.The morbidity related to blunt liver injury was 5.19％.Conclusions Non-operative therapy may be used firstly in patients with stable hemodynamics,but close monitoring should be done for changes of the life signs.Timely and reasonable choice of time and the way of surgery is important to avoid complications and reduce the mortality rate.

Objective To evaluate the effect of 3-dimmentional conformal radiotherapy (3-DCRT) for mediastinal metastasis from esophageal carcinoma after surgery.Methods Sixty-three such patients were treated by 3-DCRT. Tumor diameter was: cm 20 patients. Positive supraclavicular lymph node was found in 9 patients. The number of tumor at the upper right, upper left and upper median mediastinum was 27, 27 and 20. All patients received 3-DCRT to the dose of 40?Gy (2?Gy/f, 5f/w), after resetting of portals, the dose was boost to 64～70?Gy by 3?Gy/f, 5f/w. Dose of the patients who had been irradiated was boosted to 50?Gy without further positioning. Results Complete response rate and partial response rate were 43% and 48% one month after the treatment was concluded,with no progression of disease. The 1-, 2- and 3-year survival rates were 75%, 43% and 15%. Conclusions Three-dimmentional conformal radiotherapy, with little side-effects, can markedly improve the local control rate and suvival rate of patients with mediastinal metastasis from esophageal carcinoma after surgery.

Objective This experiment used the allogeneic bone marrow mesenchymal stem cells to cure the wound in rats .And to observe the effect and safety of bone marrow mesenchymal stem cells injection for wound heal -ing.Methods The rats with wound were divided into two groups .The rats bone marrow mesenchymal stem cells were isolated,cultured,purified,amplified and passaged.Flow cytometry instrument was used to identify the immune pheno-type of rats bone marrow mesenchymal stem cells .Local injected the rats-bone marrow mesenchymal stem cells in the rats.The difference of wound healing rate between the experimental group and control group were statistically ana -lyzed.Western blot was used to detect the expression of keratinocyte growth factor (KGF) in two groups.Histopatho-logical change of the wound was observed .Results The wound healing rate between the two groups had significantly statistical difference.After 3 days,7 days,14 days,the wound healing rates of the experimental group were (21.95 ± 8.11)%,(56.25 ±4.96)% and (79.85 ±5.44)%,respectively and which were better than those of the control group[(12.11 ±4.87)%,(30.24 ±1.53)%,(58.51 ±6.52)%](t=4.693,3.853,2.559,all P <0.05). According to the grading standards of the healing skin after HE staining ,the experimental group was better than the control group .According to the results of Western blot , the KGF protein expression of the experimental group was higher than the control group .Conclusion The allogeneic bone marrow mesenchymal stem cells may be an effective and safe method for the wound in rats .

To look into the cited literatures in Medical Journal of Chinese People's Liberation Army, all citations, including its quantity, type, language and period, in journals from 1996 to 2000 was investigated. Results: The average quantity of citations was 4 59. The citations from periodical accounted for 95 62%. The citations in Chinese and English accounted for 99 64%.The citations from 1980 to 1999 accounted for 97 35%. The results suggested that the average quantity of citations was very little. The literatures of other languages and special citations should be used more.

To find out the situations of the authors who published articles in Medical Journal of Chinese People's Liberation Army in 1996～2000, the number of authors, types of collaborated articles, organizations where the authors work were investigated. The average number of authors per article was 4.64, the collaboration rate was 93 95%, most of the collaborated articles were writen by authors working in a same organization 69 54%, trans provincial collaborated articles accounted for 15 86%, collaborated articles in a same province and internationally collaborated articles accounted for 13 03% and 1 57% respectively. The results suggested that the average number of citations was very small, and the scope of contributions should be extended in order to offer more opportunities for younger authors and to increase international collaboration.
