Objective:To study the effect of survivin expression on the mature process of dendritic cells from mouse bone marrow. Methods:The cells in marrow as the precurosor of the dendritic cells were taken from mouse in bioclean condition. Then the iDC were induced by the precurosor of DCs with GM-CSF and IL-4 in medium. ThemDC were induced by the precurosor of DCs with GM-CSF,IL-4,and TNF-? in medium. Survivin was compared by RT-PCR,and Western-bolt among these three stages. Results:The RT-PCR showed that the expression ratios of survivin mRNA among the precurosor of DCs,iDC,and mDC were(0.735?0.081),(0.596?0.073,P

Objective To detect the serum level of interleukin (IL)-1 1, lymphocyte subsets and NK cells in patients with idiopathic thrombocytopenic purpura (ITP), and explore the related factors in the pathogenesis of ITP. Methods The serum level of IL-11, lymphocyte subsets and NK cells were detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA) and flow cytometry in 50 ITP patients (ITP group) and 30 controls (control group). Results The platelet in ITP group [ (30.21 ± 19.40) ×109/L] was lower than that in control group [ (207.21 ± 31.55 ) × 109/L] obviously (P ＜ 0.05 ); the serum level of IL-11 in ITP group [(255.72 ± 163.43) ng/L] was significantly higher than that in control group [ (40.60 ± 5.57 ) ng/L ] (P ＜ 0.05 ). The correlation analysis indicated that the blood serum levels of IL- 11 had negative relationship with the platelet (r = -0.557 ,P ＜ 0.05). The percentage of CD3+ and CD4+ T lymphocyte percentage, CD4+/CD8+ in ITP group were lower and the percentage of CD8+ T lymphocyte was higher than those in control group obviously (P ＜ 0.05 ). The percentage of CD3- CD(16+56) +NK cell in ITP group was lower than that in control group (P ＜ 0.05). Conclusion IL-11, lymphocyte subgroup and NK cell change correlate with ITP morbidity closely, and the IL-11 level and the platelet possibly have the negative feedback control action.

Objective To analyze the clinical feature and diagnostic methods of patients with ischemic colitis(IC) for improving the recognition and the efficacy of therapeutic treatment. Methods Retrospective analysis of the clinical data of 30 cases of IC,including the medical history,clinical symptomatology,endoscopic appearance, histopa-thology,treatment and prognosis. Results IC occurred most of frequently in mid-aged and elders,the male-female ra-tio was 1:2.3,83.3% of the patients were over 60 years old, and most them had underlying disease. The most com-mon presenting features were sudden abdominal pain and bloody stools. Endoscopic lesions located mainly in left co-lon. Mucosal edema,erosin and submucosal bleeding were common pathological feature. Vasodilator drugs and compre-hensive medical therapy had good effects. The average duration for healing or improving was 10 days. Conclusions IC should be suspected in all elder patients with sudden abdominal pain and bloody stools. Colonoscopy is helpful for diagnosis. The prognosis is good in most cases and with rapid recovery.

Objective To investigate the relationship between transient ischemic attack(TIA)of the aged and serum CRP and plasma D-dimer.Methods A total 92 TIA aged patients,who were admitted to the Second Hospital of China Medical University of China Medical University from June 2003 to June 2005,were divided into three groups of A,B and C.All cases were measured within 24 hours the CRP and D-dimer.Head CT or MRI were carried out within 72 hours,and compared with control group,and compared between different groups of TIA.Results The levels of serum CRP and plasma D-dimer with TIA of the aged were higher than control group(P

Objective evaluate the mechanism that bacteria growing in biofilm always resist to antimicrobial agents,and to provide the theoretical basis for selecting antimicrobial agents in clinic.Methods Model of klebsiella pneumoniae bacterial biofilm were built up with the modified flat-board method and identified with the method staining with AgNO3 and confocal scanning laser microscopy.We used imipenem to induce the ESBLs production of BF bacteria.ESBLs production was performed by the standard disk diffusion method.Results The isolation rate of ESBLs producting strains in klebsiella planktonically planktonically were 20.0%(8/40).The isolation rate of ESBLs producting strains in klebsiella biofilm were 42.5%(17/40).The isolation rate of ESBLs producting strains in klebsiella biofilm being induced by imipenem were 65.0%(26/40).The isolation rate of group A and group B,groupB and group C was different from each other significantly with the statistic method of ?2-test.Conclusion One of the main reasons that klebsiella and escherichia coli resist to antibiotics is the synergetic effect of BF and ESBLs.

This paper describes the relationship between standards and intellectual property rights,describes the importance of putting the intellectual property protection into the International standards of Chinese medicine by the examples.According to the Chinese medicine's own characteristics and actual conditions in our country,the author points out some suggestions on how to put the intellectual property protection into the International standards of Chinese medicine.

Coverage of internal iliac artery during endovascular abdominal aortic aneurysm repair may cause ischemic complications in buttock,intestine,lower extremity and genital.We reported nursing care of 72 patients in our center to investigate the key points of nursing.Our experience were as follows:individualized blood pressure management and doctor-nurse cooperation in pain management were key points in preoperative nursing;close postoperative observation was focused on ischemic colitis,buttock claudication and ischemic buttock skin;cooperation with ostomy care group improved pertinency of nursing care;rounding by integration of doctors and nurses obtained high satisfaction and improved patients' compliance.

0.05). The laser group with the dose of 3 J?cm-2 showed more increase in cell survival at 24 and 48 h after being seeded as compared with control group(P

In this paper,we analyze the current situation of the national standardization on acupuncture needles and related patents.Through analyzing the international research focus on the acupuncture needle patents,we give some strategic suggestions on the intellectual property protection of acupuncture needles and traditional Chinese medicine.

Objective: To evaluate the mechanical properties of Rene95 alloy component made by laser engineered net shaping (LENS). Methods: The component was fabricated from Rene95 alloy powder by LENS, then the mechanical properties of the component, Rene95 alloy casting and dental Ni-Cr alloy casting were studied. Results: The tensile strength(MPa), yield strength(MPa), elongations(%) and the microhardness(Hv) of Rene 95 alloy component made by LENS were 1 354.27?63.44, 1 175.29?34.32, 16.53?5.85, and 464.33?10.95, those of Rene95 alloy casting 1 430.28?55.73, 1 145.52?29.78, 10.31?4.25 and 457.56? 11.38, those of dental Ni-Cr alloy casting 612.05?18.46, 426.06?12.70, 6.21?1.21 and 260.14? 6.08, respectively.Conclusion: The mechanical properties of Rene95 alloy component made by LENS were same as those of Rene95 alloy casting, better than dental Ni-Cr alloy casting.
