Wavelet transform is internationally recognized a good tool for time-frequency analysis. This paper presents a novel speckle suppression method for medical B-Scan images. The speckle is produced by scattering echoed signals in different phases because of wave interference. The software MATLAB is used as operating platform meanwhile the wavelet is used to eliminate the noise. The ultrasound image is processed by adaptive method and then the selected sym8 wavelet is used in the multiresolution analysis of the ultrasound image. The result shows that this method can effectively reduce the speckle noise.

Objective To investigate the distribution of two single nucleotide polymorphism(SNP)-717A/G and-390C/A/T-within the C reactive protein(CRP)promoter region in ethnic Han Chinese and the association with coronary heart disease(CHD).Methods Altogether positive CHD patients and negative controls were studies in this study.The two target fragments were amplied by PCR.Then the-717A/G polymorphism was screened by restriction fragment length polymorphism(RFLP)and the-390C/A/T polymorphism by Sequence Specific PCR(SSP).At last,the association was studied by proper statistical analysis.Results There was no significant difference in the distribution of-717A/G polymorphism betweenpatients and controls.However,the frequencies of allels in-390C/A/T polymorphismwere significant different between them(P

Objective To investigate the interaction between uropathogenic Escherichia coli (UPEC) and host uroepithelial cells, define the role uroepithelial cells play in initiating and modulating the host response to infection with UPEC strain. Methods The human bladder transitional epithelial EJ cells were evaluated for their capacities to allow the adherence and invasion by UPEC132, a clinical strain isolated from Tianjin, China, and a cDNA microarray for 22 000 human genes was used to identify the gene expression differences between EJ cells infected with UPEC132 and uninfected EJ cells. Results Microscope observation showed that UPEC132 could adhere to EJ cells with the adherence rate of (73.20 ± 5.26)%. And visualization by confocal microscope revealed that this microorganism could be seen within the cells. EJ cells infected with UPEC132 changed mRNA expression of a total of 29 genes, including 28 genes up-regulated and 1 gene down-regulated. Of these, regulators of growth and proliferation, cytokines, and modulators of apoptotic responses were the most prominent. Conclusion The gene expression profiling of EJ cells is affected by the infection of UPEC strain. The differentially expressed genes may contribute to further investigate the interaction of UPEC and uroepithelial cells.

OBJECTIVE To analyze the prophylactic application of antibiotics during perioperative period in surgical department and provide the scientific basis for management and rational application of antibiotics.METHODS The rational use of antibiotics during perioperative period was evaluated based on antibiotics selection,usage,dosage,the first time of application,treatment course,and the percentage of antibiotic application for cleaning operation.RESULTS All of surgical operations were used antibiotics.As for the first time of application,the use rate of thirty minutes before operation was 4.1%,but nothing used before operation was 73.2%.The treatment period after operation within 3 days was 8.1%.Among all kinds of used antibiotics,the third generation of cephalosporin accounted for 49%,and quinolones for 25%.CONCLUSIONS There are still some problems about prophylactic application of antibiotics during perioperative period in surgical department in our hospital.It is necessary to standardize application of antibiotics during perioperative period.

Objective To investigate the synergistic regulation of KDM3B and JMJD1C in leukemia. Methods The expression level of JMJD1C and KDM3B were analyzed in multiple acute myeloid leukemia (AML) cell lines. AML cell lines NB4 and HL-60 were treated with Daminozide, followed by determination of H3K9 mono-methylation and di-methylation. AML cell lines NB4 and HL-60 were treated with Daminozide, ATRA (retinoid acid All-trans), C Vitamin and the expression of KDM3B and JMJD1C were detected by real-time quantitative PCR. Results The expression level of KDM3B and JMJD1C in the AML cell lines was negatively correlated. In NB4 and HL-60 cells treated by daminozide, H3K9 mono-methylation and di- methylation level showed a rising trend in these two cell groups. After treatment of NB4 cells with the 3 reagents, the level of mRNA of KDM3B was down-regulated while the level of mRNA of JMJD1C was up-regulated. In HL-60 cells treated by daminozide, the mRNA level of KDM3B was up-regulated and the mRNA level of JMJD1C was down-regulated. Conclusion The expression of KDM3B and JMJD1C is negatively correlated in patients with AML.

Interleukin-22 (IL-22) is a member of the IL-10 family, which exhibits a similar structure and immune function with IL-10. IL-22 is mainly secreted by Th22, Th1, and Th17 cells, innate lymphoid cells (ILCs), and γδT and NKT cells. IL-22 is mainly in-volved in autoimmune diseases, malignant tumors, and infective diseases. As such, studies have focused on the function of IL-22 cyto-kine in the pathogenesis of various malignant tumors. Studies revealing the expression and pathogenesis of IL-22 in malignant tumors possibly provide a new method to treat and prevent malignant tumors. In our study, the discovery, structural characteristics, and func-tions of IL-22 in malignant tumors are reviewed.

Objective To study the clinical, laboratory, X-ray and the pathological features of Parkinson disease patients with rheumatoid-like deformities. Methods One patient was described and the relevant English literature in recent 50 years were reviewed. Results Rheumatoid-like deformities in Parkinson disease was mostly observed in women. The ratio between male and female was about 1:5.6. Joint deformities occurred after 7.6 years of Parkinson's disease in average. The manifestations of joints included the flexion of the metacarpophalangeal (MCP) joints, hyperextension of the proximal interphalangeal (PIP) joints, flexion of the distal interphalangeal (DIP) joints, and ulnar deviation of wrists and bilateral feet hallux valgus. Whole-blood analysis, biochemistry profile, erythrocyte sedimentation rate, C -reactive protein were all in normal range. Rheumatoid factor and ANA, anti-ENA profile, AKA, anti-cyclic citrullinated peptide (anti-CCP) antibody and antiperinuclear factor (APF) were all negative. Periarticular erosion was not observed in plaint X -ray films. Synovial pathology showed non -specific infla -mmation without classical syno vial membrane proliferation and pannus formation. NSAIDs and DMARDs were uneffective, but on the contrary, anti -parkinson' s disease therapy could relieve joints symptoms. Conclusion Parkinson disease can be accompanied with rheumatoid-like deformities which may be misdiagnosed as RA and should be differentiated from RA by laboratory, radiographs and synovium pathology examination.
