[Method] Choose 38 children patients as research objects who were diagnosed as infectious mononucleosis with positive throat swab culture, and make investigation to the separated pathogenic bacteria distribution and drug resistance.[Result] In the 38 cases of samples, there ’re 44 strains of pathogenic bacteria detected(2 kinds of pathogenic bacteria detected in 6 cases respectively), the front 3 were: 14 strains of staphylococcus aureus(31.8%), 10 acineto-bacter baumannii(22.7%) and 8 klebsiel a pneumaniae(18.2%); the staphylococcus aureus had highest drug resistance to Penicilin G, occupying 85.7%; to ampicil in, cefoxitin and macrodantin, the acinetobacter baumannii had drug resistance 100%; the klebsiel a pneumaniae had drug resistance of 100% to ampicil in.[Conclusion] The pathogenic bacteria distribution and drug resistance of children patients with infectious mononucleosis combined with bacteria infection have definite features, which shal be emphasized in diagnosis and treatment.

The separation and purification of beta chains of globm from the inbreeding SMMC/B mice were performed by the dissociation of chains in urea, CMhcellulose column chromatography for the separation of alpha and beta chains, and Sephadex G25 column chromatography for removing salts. The pure beta-chain was digested by trypsin. Digested fragments were resolved by cellulose membrane two-way electrophoresis, thus obtaining the map of spots of beta-chain fragments for B33, B34, Bp(), Bp and Bf. The spots,BTp3, which have the same positions ,were separated and micro-sequences were assayed by DABITC/PITC double coupling technique. According to the genetic code, we might deduce the nucleotide sequence of their mRNA from the known amino acid sequence of BTp3, a piece of beta-chain. By analyzing the altered genetic loci of beta-chain of globin, we might determine the genetic purity of the strain and distinguish objectively the genetic types between species and subspecies.

Background Many surgical techniques are used to improve the postoperative visual acuity for rhegmatogenous retinal detachment(RRD)during recent decade,and scleral buckling surgery is one of these operations.Whether the visual function after operation can be rescued is an important issue. Objective The aim of this study was to analyze the risk factors of influencing the postoperative vision following scleral buckling surgery for primary macula-off RRD. Methods The clinical and follow-up data from consecutive series of 116 eyes of 116 patients received scleral buckling surgery for primary maeula-off RRD were retrospectively reviewed.The relationship of multiple factors,including age,preoperative best corrected visual acuity(BCVA),duration of disease,refractive error,location of retinal hole,number of retinal hole,area and height of retina detachment,management of subretinal fluid and intravitreal gas injection,with visual acuity were analyzed respectively by χ2 test.The correlations among statistically significant factors with postoperative vision were analyzed by multivariate Logistic regression analysis.Written informed consent was obtained from any patient before surgery. Results The postoperative vision outcome was found with significantly difference among different preoperative vision groups(P=0.002)and different course (P=0.009).There were significant differences between the groups with different preoperative BCVA(P=0.002)and duration of disease(P=0.009).Multivariate Logistic regression analysis showed that the preoperative BCVA was the only variable affecting postoperative visual result(r=0.400,P=0.009).Considerable linear correlation wag seen between preoperative vision and postoperative vision(r= 0.400,P=0.000).The probability with postoperative vision of t>0.4 in the eyes with preoperative≥0.05 was 3 folds more than that of preoperative<0.05(OR=2.992).The better visual outcome after scleral buckling surgery was seen in the eyes with the course≤7 days. Conclusion Preoperative BCVA and duration of disease are the key factors associated with the postoperative BCVA.Scleral buckling surgery should be performed within the first week for primary macula-off RRD.
