To obtain human antibodies against the Gn protein of Severe fever with thrombocytopenia syndrome virus (SFTSV) with phage display technology, this study aimed to screen anti-Gn protein antibodies from an anti-SFTSV Fab human phage display library. Antibody genes were identified by sequence analysis and the specificity of antibodies was confirmed by ELISA. The Fab antibody genes were cloned into the HL51-14 vector and expressed in a mammalian cell expression system. IgG antibodies were then purified by protein A affinity chromatography,and the results were further confirmed by ELISA,IFA,western blotting assays and micro-neutralization tests. The results showed that, after three rounds of panning, there were 390 human Fab antibodies against SFTSV particles, of which 364 were specific for nucleoprotein. Coated with the Gn protein, eight different Fab antibodies specific for Gn protein were obtained after the determination of the subtype and subclass of antibodies by gene sequencing; five of these antibodies were from the Lambda library and three were from the Kappa library. The eight IgG antibodies could specifically bind to Gn protein according to the ELISA, IFA and Western blotting assays. The micro-neutralization test showed that these eight antibodies had no neutralizing activity,but they could still provide a reference for research in human monoclonal antibodies against SFTSV.

OBJECTIVE:To optimize the placement of extra-machine medicines in the automated pharmacy and establish a ra-pid dispensing area to shorten medicine dispensing time. METHODS:12 588 prescriptions made within one week were collected from the outpatient pharmacy of our hospital,in which 29 kinds of extra-machine medicines used frequently were clustered on the basis of Pearson correlation coefficients. The extra-machine medicines used at a higher frequency were arranged in the storage posi-tions near to the medicine dispensing window,and those related to the above-mentioned medicines were stored in the positions adja-cent to them,thereby a rapid dispensing area was established. The effect of the above-said method was evaluated by comparing the time it took for the pharmacist to dispense medicines one week before and after the establishment of the rapid dispensing area. RE-SULTS:29 kinds of extra-machine medicines were clustered into 4 major categories,and stored in 4 positions in the rapid med-icine dispensing area respectively,and then the position codes were assigned. After the rapid dispensing area was established,the average single prescription dispensing time for the pharmacist decreased by about 9 s (40.43 s vs. 31.43 s,P<0.01). CONCLU-SIONS:The establishment of the rapid dispensing area based on cluster analysis method has increased the efficiency of dispensing medicines in the outpatient pharmacy of our hospital.

Objective To explore the bone marrow pathology ,diagnosis and differential diagnosis of Waldenstrom macroglobulinemia(WM). Methods 19 WM patients was examined by bone marrow aspiration (BMA) and bone marrow biopsy (BMB) for morphology. Flow cytometry (FCM) and immunohistochemistry (IHC) for immunophenotyping. Results Plasmacytoid lymphocytes were identified in 11 BMA. All of 19 BMB were involved by lymphoma cells. 17 cases showed a predominance of small lymphocytes and 2 of plasmacytoid lymphocytes. Typically plasmacytoid lymphocytes were not seen in 4 cases. Patterns of bone marrow involvement were as follow: diffuse (12 cases), nodular (4 cases), interstitial (3 cases). Immunophenotypically, FCM showed all cases were CD_(19)~+, CD_(20)~+, CD_(22)~+, CD_5~- and CD_(10)~-. IHC revealed small lymphocytes and plasmacytoid lymphocytes were Pax5~+ CD_(20)~+ and plasma cells were CD_(38) CD_(138)~+ CD_(20)~- Pax5~-. Conclusion Small lymphocytes proliferation with plasmacytic differentiation is the typical bone marrow pathologic features of WM. IHC is benefit for identifying lymphocytes and plasma cells components. The Combination of morphology, FCM and IHC is contributive to the diagnosis and differentiation of WM.

Objective To investigate the effects of virus coinfection on the severity of respiratory syncytial virus(RSV)bronchiolitis through the clinical analysis of 286 cases.Methods Various virus antibody were measured by using ELISA in 286 cases of RSV bronchiolitis.The frequency of respiratory virus coinfection on the severity of RSV bronchiolitis was observed.Results RSV bronchiolitis complicated with virus coinfection ratio reached 29.37%,especially with the double infection.Compared to patients with RSV infection,the severe cases increased sig-nificantly in patients with virus coinfection(χ2 =128.7,P<0.01).Conclusion Other respiratory viruses coinfection are not uncommon in infants with RSV bronchiolitis and may increase the severity of RSV bronchiolitis.

Objective To study the relationship between the changes of diffusion tensor imaging(DTI)and diffusion tensor tractography(DTT)of optic radiation and the defect of visual field.Methods DTI and DTT were performed in 37 patients with invasion of the optic radiation by intracranial lesions and in 20 normal control group at 3.0T MR scanner,the visual fields of all cases were examined.The relativity between FA values,ADC values and mean sensitivity(MS)values,mean defect(MD)values of visual field and the relativity between the morphological change of optic radiation and the defect of visual field were analysed.Results In comparison with control group,FA values decreased and ADC values increased in subject group,there were statistically significant differences(P＜0.001)between them.In disordered group,FA values were positive correlation with MS values(r=0.718)and negative correlation with MD values(r=-0.694);ADC values were negative correlation with MS values(r=-0.625)and positive correlation with MD values(r=0.538).DTT showed that the ventral tracts of optic radiation were damaged which oppeared as the defect of ditto quadrant of bilateral field vision in 9 cases,the dorsal tracts and the lateral tracts of optic radiation were damaged which appeared as the defect of inferior quadrant of bilateral field vision in 7 cases,the optic radiations were damaged extensively that caused symmetric or asymmetric congruous hemianopia of bilateral field vision in 21 cases.Conclusion DTI and DTT of optic radiation are intimately correlated with the examined results of visual field,it will be a objective index to extimate the function and the morphological changes of optic radiation.
