Objective To construct human-mouse hybrid Fab phage antibody libraries and to select target Fab genes. Methods With Fd repertoire genes of PBMC from hepatoma patients and the chemeric light chain gene of cFab-HAb18, two hybrid Fab phage antibody libraries(pComb3 and pComb3X) were constructed. The GST fusion and non-fusion HAb18GE were used as antigens to select the target antibodies with the optimized strategies of amplifying and screening. Results When pComb3 displaying library was cultivated at 37℃, the target fragments could not be cut out with the restriction endonucleases from most clones of the library, which was an indication of “recombinant-deletion”. But no “recombinant-deletion” was found in pComb3X displaying library. Because of the serious cross-reaction, the phage-display Fab ELISA could not be used for the selection of positive clones. But positive clones could be identified in the supernatant of lysate with ELISA afterbeing induced by IPTG. Conclusion Through the construction of HuMFab phage antibody libraries and the optimization of screening strategies, we get the desired HuMFab genes for subsequent research.

ObjectiveTo a nalyze the morphologic features of SMMC-7721 cannibalistic cells that induced by triazole Schiff base derivative(LH-37) in vitro. Methods The SMMC-7721 cells (1×10~4/ml)were cultured in the medium containing of 1×10~(-5) mol/L LH-37 for 24h,48h.The character of cells was detected by Papanicolaou and Wright′s Staining. Immunohistochemical method was used to observe the cleaved Caspase-3 positive cells. The ultrastructure of cannibalism cells was observed by JEM 100CX-II transmission electronic microscope. Results Microscopic analysis demonstrated the complete internalization of one cell within another. We noted that some cannibalistic cells in small aggregates appeared to be inside of large vacuoles, suggesting that they were internalized within a neighboring cell. The proportion of cannibalistic cells were increased after SMMC-7721 cells were cultured in the presence of LH-37 for 48 hours. The proportion of the cannibalistic cells in control and LH-37 group was 0.47% and 5.23% respectively . Many internalized cells were positive for cleaved caspase-3 staining . Ultrastructural analysis of engulfed cells from 24 hours exhibited evidence of live-cell internalization consistent with cannibalism, The most common fate for internalized cells was death after treatment with LH-37 for 48 hours, as evidenced by nuclear degradation and the eventual disappearance of some cells within the enveloping cell . Conclusion The data presented indicate that LH-37 can lead to an increase of cannibalism in human hepatocarcinoma cell in vitro.

OBJECTIVE To explore the incidence rate,pathogen distribution and characteristics of drug resistance of ventilator-associated pneumonia(VAP) patients due to acute lung injury and acute respiratory distress syndrome(ALI/ARDS) after severe injury,and analyze impact factors on VAP.METHODS All 183 cases with ALI/ARDS after severe injury from Jan 2004 to Mar 2008,were admiitted and given mechanic ventilation over 48 hours in our ICU and EICU.RESULTS VAP was found in 98 cases,accounted for 53.56%.Among them,42 were early-onset VAP and the other 56 were late-onset VAP.Altogether 276 pathogens were isolated,and most of them were Pseudomonas aeruginosa,Staphylococci aureus,Klebsiella pneumoniae,Acinetobacter baumannii and Escherichia coli.In 41 cases only one pathogen was isolated,the other 57 cases were with two or above pathogens.The revealed important risk factors were coma,prolonged mechanical ventilation,tracheotomy,antiacid treatment,use of antimicrobial agents and low albumin.CONCLUSIONS The incidence rate of VAP due to ALI/ARDS is high,and most of the isolated pathogens are drug resistant.Mixed infections are found commonly in these cases.

Objective:To study the diagnosis value of Transcranial Doppler ultrasound for intracranial artery stenosis in patients with cerebral infarction.Methods:A total of 140 patients with acute cerebral infarction,transient ischemic attack and posterior circulation ischemic attack in Department of Neurology,Xinjiang cardiovascular and cerebrovascular disease hospital from October 2014 to October 2016 were selected as research object,CT angiography (CTA) and TCD detection were performed in all patients.Used CTA examination results as the gold standard,the detection results of intracranial artery stenosis in two groups were compared,the diagnostic value of TCD and the diagnostic results of TCD to the degree of bilateral middle cerebral artery (MCA) stenosis were analyzed.Results:CTA diagnosis showed that 140 patients had a total of 105 patients with intracranial artery stenosis,in the anterior and posterior circulation vessel of 1155 intracranial segments,CTA detection showed that 249 vessels were narrow,TCD detection showed that 236 vessels were narrow.Com-pared with CTA,TCD was better in the diagnosis of patients (Kappa value＞0.75).The diagnostic sensitivity and positive predictive value of TCD for MCA were the highest,which were 91.26％ and 93.07％,the consistency was the best (Kappa value =0.917).CTA detection showed that 210 MCA vessels had 103 stenoses,mild stenosis 17,moderate stenosis 41,severe stenosis 45,TCD detection showed that the stenosis was 101,mild stenosis 16,moderate stenosis 40,severe stenosis 45.The Kappa test showed that the diagnostic results of TCD to the degree ofMCA stenosis was better consistency compared with CTA (Kappa value=0.884.Conclusion:TCD has a high diagnostic value for cerebral artery stenosis in patients with cerebral infarction,and it is consistent with the diagnosis of CTA.

Objective: To select anti-HAb18G (hepatoma associated antigen) human Fd fragments with guided selection of L chain of chimeric Fab-HAb18. Methods: The human Fd repertories genes were amplified by RT-PCR from PBMC of hepatoma patients, and cloned into the vector pComb3X with chimeric L chain to construct the human-mouse hybrid Fab phage library. HAblSGE, extracellular region of HAblSG, was used as antigen to screen. The positive clones was obtained by ELISA and FCM with p Ⅲ-fusion Fab antibody. The DNA sequences were analyzed. Results: A human-mouse Fab antibody library were constructed with 2?107 PFU. After 6 rounds panning, 7 positive clones were obtained with ELISA and FCM. And sequences of 2 clones with better affinity were same. The CHI belonged to the IgG2 class as the parent Fd, and the variable region belonged to VH3 family. Conclusions: Through the construction of the HuMFab phage antibody library and chemeric L chain-guided selection, we get the available human Fd fragments for subsequent research.

Objective To study the value of chest radiograph and thin-section computed tomography (CT) in diagnosis bronchiolitis obliterans in children, and to determine clinical view of obliterative bronchilitis in children. Methods We identified 12 infants, 10 boys, and 2 girls (age range, 5 month to 11 years) with clinical confirmation of bronchiolitis obliterans. Three cases were after Steven-Johnson syndrome, 8 were post-infection(2 adenovirus, 2 measles and 1 Pseudomonas aeruginosa infection, 3 cases were unknown etiology infection) ; The symptoms lasted for at least 6 weeks. One case had lung ventilation nuclear scan. We evaluated individual bronchscopy, pulmonary function test, chest radiograph and thin-section CT features and their characteristic appearance. Results All cases had typical clinical characteristics and pulmonary function testing results that were consistent with nonreversible small airways obstruction. One case had lung ventilation nuclear scan illustrated absent and reduced ventilation of the right lower lobe. Nine cases who underwent bronchoscopy were chronic endobronchial inflammation. Three children had transbronchial biopsy and 1 patient who underwent open pulmonary biopsies were uncertain of histological diagnosis. Chest radiography showed hyperinflation in 8 cases; peribronchial thickening in 6 cases; consolidation/atelectasia in 6 cases; unilateral hyperlucency of a small/normal-sized lung in 4 cases. Thin-section CT/HRCT features included: mosaic perfusion pattern, decreased lung attenuation in 11 cases, pulmonary vascular attenuation in 10 cases; bronchial dilatation in 7 cases; bronchial wall thickening in 9 cases; unilateral hyperlucency of a small/normal-sized lung in 5 cases; consolidation in 6 cases; nodular in 3 cases; mucoid impaction in 5 cases. Conclusions In our study, correct diagnoses of bronchiolitis obliterans in children were made more special with thin-section CT than with chest radiographs. The diagnosis of BO in children can be based on the characteristic clinical situation, pulmonary function, indicating minimally reversible airways obstruction and characteristic thin-section CT findings.
