Objective To understand the relationship between Demodex and bacteria infection in rosacea (brandy nose), and to find effective means for the treatment. MethodsCellophane tape was used to detect Demodex on the nasolabial grooves and the face; sebum and tissue on face was scraped and cultured to examine bacteria under microscope. The hospital_made anti_rosacea lotion was used on the affected part two times a day for 7 days. Results It was found that 193 (74^2%) of 260 cases with rosacea were infected by Demodex and 209 (80^4%) of the patients were infected by bacteria. The overall effective rate of the treatment for rosacea was 73^5%. Conclusion Bacteria infection in rosacea is an important factor inducing rosacea. The curative effect of the anti_rosacea lotion is good.

Objective:To evaluate the performance of paramagnetic particles chemiluminescence microparticle immunoassay ( CMIA) for detection of serum Vitamin B12 ( VitB12 ).Methods: Analysed CMIA system precision, accuracy, anti-interference, analytical measuring range( AMR) ,clinical reportable range ( CRR) and biological reference interval were evaluated,according to the clinical and laboratory standards institude ( CLSI) EP5-A2,EP15-A2,EP7-A2,EP6-A,C28-A3c guidelines.To assess the accuracy,we used the reference material SRM 1955 from national institute of standards and technology ( NIST ) and external quality assessment ( EQA) samples ( LN5-B and K-C) from CAP.Results:The precisions of within-run and between-run were less than standard of manu-facturer when the concentration of VitB12 was 108.84-874.43 pmol/L.The results of SRM1955 met the allowable range of the target val-ue.The results of EQA samples( K-C and LN5-B) also up to the CAP calibration and validation/linear evaluation error limits stipulated standards,and the results through linear verification when the concentration of VitB12 was 89-1 057 pmol/L.The 95% verification interval contains the specified value also.The relative deviation was less than external quality assessment standard from national center for clinical laboratory ( TEa:target value ±25%).Anti-interference evaluation showed without significant interferenc when TG ≤20 mmol/L,Bil ≤300 μmol/L VitC≤1.5 g/L to the VitB12 detection system ( CMIA).AMR validation showed determines the best fit equation was linear equation polynomial.There was the linear relationship when the concentration of VitB12 was 0-1 107 pmol/L.The upper limit of CRR was 110 700 pmol/L,the maximum dilution was 100 times.Biological reference interval validation showed that the overall level of VitB12 in this study reference individuals conform to the standard of manufacturer statement for the population,the overall level of VitB12 in female little higher than male,but no significant differences.Conclusion:Performance of CMIA for detection of serum VitB12 basically met needs of laboratory,which can provide reliable results of VitB12 for laboratory,provide information for the VitB12 status of population in the laboratory evaluation.

OBJECTIVE:To improve the writing quality prescriptions of traditional Chinese medicines and to facilitate the standardization of traditional Chinese medicine prescriptions.METHODS:A total of 15 000 prescriptions were sampled in our hospital in 2006 for an analysis of the problems in accordance with the related standards specified in Chinese Pharmacopoeia(CP,2005 edition)and the new "Prescription management method".RESULTS:The problems manifested as nonstandard in drug name and footnotes,or overdosage and so on.CONCLUSION:We should strengthen the management of the traditional Chinese drugs and improve our pharmaceutical care.

Objective To describe the sonographic appearance of mesenchymal hamartoma of the liver(MHL)and to analyze the diagnostic value of ultrasound.Methods Eleven surgically and pathologically confirmed cases of MHL from January 2005 to May 2011 in the Beijing Children′s Hospital were retrospectively reviewed.Results Ultrasound examinations showed 9 cystic hamartomas,including 7 multiseptate cystic and 2 monocystic lesions.Of the 7 multiseptate cystic hamartomas,4 had a honeycomb appearance and 3 had irregularly-distributed multiple cysts with varied septations.Of the 2 monocystic hamartomas,1 had a large cystic portion while the other was mainly solid with approximately 4% cystic portion of the tumor.Two cases in this group were solid,presenting with a well-defined homogenous mass.Conclusions Ultrasonography is an effective imaging modality for the diagnosis for MHL.A mixed or a mainly-cystic liver mass found in a child less than 2 years old should be suspicious for MHL.

Objective To assess the relationship between Helicobacter pylori(Hp) infection and idiopathic thrombocytopenic purpura (ITP) in children.Methods All the published literatures of relationship between Hp infection and childhood ITP were searched by computer and manual search from 2000 to 2010 in the CNKI database,WANFANG database,Chongqing Vip database and Pubmed database.A comprehensive analysis of case control studies were used by Meta analysis and calculated the value of integrated OR and 95%CI.Results Thirty-five pertinent literatures were collected.After literature which study methods not fit the request were ruled out,there were 8 effective documents in all,including 6 Chinese literatures,and 2 English literatures.Meta analysis of OR value and 95%CI were 1.90(1.44-2.50),and Z value of combined effect of tests was 4.56 (P=0.000 01) in ITP group and control group.Meta analysis results of OR value and 95%CI were 0.74(0.49-1.13),and Z value of combined effect of the test was 1.38 (P=0.17) in acute ITP and chronic ITP group.Conclusions Hp infection is closely related with the incidence of ITP,but has nothing to do with the type of ITP.

Objective To investigate the CT manifestations of Meckel's diverticulum and its complications in children. Methods Retrospective analysis of Clinical and CT findings in 25 cases with pathologically proved Meckel's diverticulum. The unenhanced and contrast-enhanced CT were obtained in all patients. Results (1)The direct signs: the diverticulum cannot be shown in 5 cases; the diverticulums were found around the navel or in lower right abdomen in 20 cases. The blind-ending fluid-filled or gas-filled structures were found in 9 cases, with heterogeneous ring-enhancement. The tubercle-like structures were detected in 11 cases, which showed no enhancement in 4 cases, and homogeneous enhancement in 3 cases,and heterogeneous enhancement in 4 cases. (2) The indirect signs included intestine obstruction in 8 cases,swelling fat layer surrounding the diverticulum in 9 cases, free gas around the diverticulum in 3 cases,thickened mesentery in 8 cases, ascites in 4 cases, and intussusception due to inverted Meckel's diverticulum with "target sign" in 1 case. (3) CT classification: with diverticulitis or diverticular bleeding in 20 eases; with intestine obstruction or intussusception in 8 cases; bands-caused obstruction in 7 cases;intussusception in 1 case; with perforation in 3 cases. Conclusion Meckel's diverticulum and its complications have typical CT findings, and CT can clearly demonstrate diverticulum's shape, margin,internal components and surroundiug tissues.

In order to enhance the specificity of TNF-α monoclonal antibody to inflamed site, a bispecific antibody BsDb that targets TNF-α and the extra-domain B (ED-B) of fibronectin (FN) was constructed by covalently linking the anti-TNF-α single chain Fv antibody (TNF-scFv) and the anti-ED-B scFv L19 via a flexible peptide linker deriving from human serum albumin (HSA). ED-B is an antigen specifically expressed at the inflamed site. BsDb is expressed in E. coli, identified by immunoblot, and purified with affinity chromatography. This was followed by further examination of its bioactivities and pharmacokinetics. We demonstrated that BsDb retained the immunoreactivity of its original antibodies as it could simultaneously bind to TNF-α and ED-B and neutralize the biological action of TNF-α. In the collagen-induced arthritis mice model, BsDb selectively accumulate in the inflamed joint with a maximal uptake of (12.2 ± 1.50)% ID/g in a single inflamed paw and retain in the inflamed paw for at least 72 h. In contrast, BsDb showed a short serum half-life of (0.50 ± 0.05) h and a rapid clearance from normal tissues. The findings reported herein indicate that BsDb has good specificity to the inflamed site and low toxicity to normal tissues. BsDb is therefore likely to have greater clinical applications in the treatment of rheumatoid arthritis and other autoimmune diseases. This laid a stable basis for its preclinical study.
