Objective To evaluate the diagnostic value of myocardial enzymes on the cardiac muscle injury for the children with acute mycoplasma pneumonia(MP).Method The levels of phosphocreatine kinase-MB(CK-MB),lactate dehydrogenase(LDH),aspartate aminotransferase(AST)in 48children with MP(MP group)were measured,48 normal children served as control group.Results The levels of AST,LDH,CK-MB were(37.18±6.15),(294.10±46.20),(84.50±13.70)U/L in acute stage in MP group,they were higher than those in control group[(25.14±10.50),(140.50±76.21),(19.50±4.10)U/L](P＜0.01).All the values above was descended in recovery phase in MP group,but the values of CK-MB[(27.80±8.40)U/L]and LDH[(189.50±69.73)U/L]were still higher than those in control group(P＜0.01 or＜0.05).Conclusions Children with MP may combine myocardial injuries and CK-MB isa parameter to diagnose the damage.Protection therapy for cardiac muscle should be performed on the children with MP.

B7H1 is a recently described B7 family member.Ligation of PD-1 receptors with B7hl on the surface of activated T cell inhibits T cell proliferation and cytokine production. B7H1 plays a negative regulatory role in peripheral tolerance, autoimmune diseases and chronic infections.B7H1 also has been found to be largely expressed on a broad range of cancers and is thought to contribute to immune evasion by cancers. Blockade of B7H1/PD-1 pathway may contribute to the treatment of autoimmune diseases and maligant tumors.

Flow cytometric immunophenotyping has evolved from two-parameter quantitative measurement of peripheral blood lymphocytes to five-or more parameter qualitative evaluation of bone marrow and lymph node in hematopathology.Leukemia/lymphoma immunophenotyping represents an important addition to histomorphology in the diagnosis,classification and monitoring of hematolymphoid neoplasms.The complexity of five-or more parameter analyses and the interpretation of the data rely on standardization and validation of the instrument,the reagent and the procedure.In addition,clinical flow cytometry laboratories in U.S.A are required to document proficiency testing,sample preparation as well as accuracy,specificity,sensitivity and precision of methodology.CLSI and UCCC recommend that each laboratory should validate its own qualitative and quantitative procedures.This paper introduces the procedures for validation and quality control in a clinical flow cytometry laboratory in the United States.

Objective To explore the relationship between the type of TORCH infection and pregnancy outcome through the de-tection of TORCH infection in pregnant women with IgG avidity index (AI) .Methods Collected each type of TORCH pathogens IgM positive maternal serum ,and detect the IgG avidity index and track the outcome of pregnancy .Results The rate of TORCH pathogens recent infection (AI<30% )in pregnant women ,HSV ,RUB ,CMV ,TOXO respectively were 0 ,3 .8% ,9 .3% ,7 .9% ;In the group of pregnant women with TORCH-IgG AI<30% ,there were 2 cases of pregnancy outcome of abnormal (missed abortion) and one case of fetal malformations (hydrocephalus) .Conclusion In the recent infection of TORCH pathogens in pregnant women , mainly are non-primary infection ;The damage of cytomegalovirus and Toxoplasma gondii primary infection to the fetus is much larger than the non-primary infection .

OBJECTIVE To investigate the resistance rates of Gram negative bacilli and the distribution of ?-lactamases in hospital infections(HI) or community acquired infections(CAI) in Tongling.METHODS Antimicrobial(susceptibility)(test) was done on 356 strains of Gram negative bacilli isolated in Tongling from Oct 2003 to Sep 2004 by Kirby-Bauer method.The detection of ESBLs and AmpC ?-lactamases was performed by three-dimensional test,MBL by the double-disk synergy test.RESULTS Among total 356 strains of Gram negative bacilli,267 were with HI(53.9%) isolated from sputum of patients,89(34.8%) were(isolated) from CAI patients and urine.The antimicrobial susceptibility rates of Gram negative bacilli from CAI patients was significantly higher than that from HI patients,for Acinetobacter baumannii they were 1.5 to 3.0,for(Pseudomonas aeruginosa) were 1.2 to 1.6.No strains of Escherichia coli and Klebsiella pneumoniae were found resistant to imipenem.Among 356 Gram negative bacilli,77 strains hyperproducing ESBLs and AmpC ?-lactamases,the detection rate was 21.6%, 69 strains were isolated from HI patients,and 8 strains were from CAI patients.From strains resistant to imipenem had 13 strains detected MBL,the detection rate was 52.0%.All of them were isolated from HI patients.CONCLUSIONS The resistance of Gram negative(bacilli) is a serious problem in Tongling.The antimicrobial(susceptibility) rates of Gram negative bacilli from CAI patients are significantly higher than those from HI patients.Gram negative bacilli produce all kinds of(?-lactamases,) such as ESBLs,AmpC(?-lactamases) and MBL.

Objective:To discuss the clinical efficacy of minimally invasive locking plate and the traditional open reduction with internal fixation in the treatment of proximal humerus fractures.Methods:89 cases of patients with proximal humeral fractures were selected and divided into two groups according to different surgical methods.The observation group (45 cases) was given minimally invasive locking plate,while the control group (44 cases) was treated with the traditional open reduction and internal fixation.The operation time,hospitalization time,fracture healing time,intraoperative blood loss,Neer score and Constant-Murley score at 1 month after postoperatiion were compared between two groups.Results:The operation time,hospitalization,fracture healing time of observation group were significantly shorter than those of the control group,and the bleeding amount of observation group was less than that of the control group (P＜0.05).At 1 months after operation,the Constant-Murley scores of observation group were significantly better than those of the control group (P＜0.05).The For Neer scores,excellent rate of observation group (91.1％) were significantly higher than those of the control group (68.1％,P＜0.05).Conclusion:Compared with the traditional open reduction with internal fixation,minimally invasive locking plate was better,safer,faster and more effectively for promoting the recovery of shoulder function of patient with proximal humerus fractures.

Aim To investigate the effects of PLCε on the invasion and migration of human osteosarcoma cancer cells U2OS. Methods RNA interference ( RNAi) was used to inhibit PLCεexpression, and the proliferation of cancer cells was measured by CCK-8 assay. The migration of the cells was measured by scratch wound healing assay and migration chamber as-say. Gelatin zymography was performed to measure the MMP2 activities in U2OS cells. Results PLCε ex-pression was suppressed by siRNA. CCK-8 assay showed that PLCε had no effect on the proliferation of cancer cells. PLCε knockdown inhibited cell invasion and activities of MMP2 . Conclusion PLCε knock-down can inhibit the migration and invasion of human osteosarcoma cancer cells U2OS.

Objective:To provide reference for the treatment of lipoprotein glomerulopathy and to investigate the participation of clinical pharmacists in the whole treatment course. Methods: Three different treatment regimens, including immunosuppressive thera-py, dual plasma filtration therapy and lipid-lowering combined with reducing urinary protein therapy was respectively adopted for one patient with lipoprotein glomerulopathy, and the efficacy was evaluated. Clinical pharmacists assisted physicians in deciding treatment regimen, performed pharmaceutical care, adjusted medication and analyzed the prognosis of the patient during the follow-up. Results:1. Immunosuppressive therapy was ineffective for the patient;2. The dual filtration acted quickly, while the expense was high and the disease was easy to relapse;3. The third therapy was relatively safer and more economical with long-term effect. Conclusion:Combi-nation therapy of lowering lipid and reducing urinary protein is the most suitable treatment regimen for the patient with lipoprotein glo-merulopathy. Clinical pharmacists play an important role in the whole course of treatment to assist physicians in obtaining the maximum benefit of patients.
