Objective To explore the observation and nursing of the surgery of dysembryoplastic neuroepithelial tumors (DNT) in the function zone of brain.Methods A retrospective analysis of the clinic data of 5 patients receiving the surgery for the dysembryoplastic neuroepithelial tumors (DNT) in the function zone of brain was carried out,the clinical nursing experience was summarized.Results The EEG was re-examined 1 week after surgery.4 cases showed roughly normal EEG,one case with rare slow wave.The re-examined EEG 3 months after surgery suggested 3 cases were normal and 2 cases were almost normal.No epilepsia occurred after 6-month follow-up.Conclusions For DNT patients,microsurgical resection of the tumor is effective and enhancing the patients' perioperative observation and nursing has a significant meaning to increase the success of surgery,reduce complications,promote the rehabilitation of patients and improve the quality of life of patients.

Objective Construction of human IL‐4 recombinant expression vector and then conduct the expression ,purification and identification of human recombinant IL‐4 .Methods the open reading frame of IL‐4 was amplified by nest PCR with total RNA from PBMC of healthy volunteer .And then the amplified IL‐4 was inserted into pET101/D‐TOPO ,transformed into BL21 ,ex‐pressed ,purified and indentified .Results The size of amplified open reading frame of IL‐4 was about 460 bp and the sequence was correct .After transformed into BL21 ,the IL‐4 clone with higher expression level was selected by selection of different clones insert‐ed with IL‐4 and the size of expressed ,purified IL‐4 was about 28 × 103 .Western blot results showed that the size of single band was identical with the expected protein .Conclusion Human IL‐4 recombinant protein was got successfully .

Objective:Expression and purification of the α-HL of Staphylococcus aureus as antigen for making full human anti-α-HL antibody later ,providing of new treatment for Staphylococcus aureus infection.Methods:The total RNA of Staphylococcus aureus was extracted and the cDNA of α-HL was amplified by RT-PCR.The DNA of α-HL and pCold-TF plasmid was digested and ligated by T4 ligase and then transformed into E.coli TOPO 10.The recombinant plasmid α-HL/pCold-TF which verified by sequencing was trans-formed into E.coli BL21 for expression.The expression products was identified by SDS-PAGE and Western blot.Results: The size of amplified cDNA of α-HL was about 900 bp and the expressed soluble fusion protein of α-HL was about 90 kD(including the molecular chaperone in the vector ) after inducing expression for 24 h at 15℃.The Western blot results showed that the expressed protein was the fusion protein of α-HL.The purified α-HL was injected into BABL/c mice for making antiserum.The results showed that the antiserum had good binding activity with Staphylococcus aureus and the titer was greater than 10 000 times.Conclusion: The α-HL of Staphylococcus aureus was successfully cloned and the soluble fusion protein of α-HL was successfully expressed.

Objective:To develop non-immunized human phage display library.Methods:The total RNA of lymphocyte cells from peripheral blood of healthy voluntee was isolated and cDNA was synthesized,and the genes of heavy variable chain (VH) and light variable chain (V? and V?) were amplified by direct PCR and half-nested PCR.By overlapping extension PCR,the genes of VH and VL (V? and V?) were linked.The linked genes of single chain Fv fragment (scFv) were ligated with the vector pCANTAB-5E and then cloned into TG1 for the scFv library construction.Results:By direct PCR and half-nested PCR,42 VH fragments,16 V? and 18 V? fragments were obtained.The size of linked scFv library genes was 750 bp and the volume of constructed scFv library was 1.35?108.The results of BstN Ⅰ analysis of scFv genes from the phage library showed that fingerprint map of the selected scFvs was different.Conclusion:The developed phage library is diversity and can be used for selecting humanized scFv.

【Objective】 To observe the therapeutic effect of acupuncture for autismin children.【Methods】Subjecting tothe willing of the children s parents,80 children with autismwere equally dividedintotwo groups :group Areceived acupuncture mainly onthe ten groups of acupoints for autism,whichis founded by Professor Jinrui,qd,sixtimes per week,suspension of medication on Sunday,and 120 times constituting one treatment course;group Breceived physical therapy,cognitive training,behavioral analysis and correction,linguistic training,qd,4 hour for eachtime,sixtimes per week,suspension of medication on Sunday,and 120 times constituting one treatment course.After treatment,the therapeutic effect was evaluated with functional development scale in Chinese version of Children Psychoeducational Profile(C-PEP).【Results】After one treatment course,the scores of functional development were increasedin both of groups Aand B(P

Objective: To study the distribution of Langerhans cell (LC) in oral lichen planuss (OLP). Methods: LCs in oral mucosa samples were examined with monoclonal CD1a antibody and an immunohistochemical technique(LAB method) in 35 cases of OLP and 6 cases of health control. Results: On average, in the samples of OLP the CD1a positive LCs counted under microscope in each field of 40 ? 10 were 5. 78 in epithelial cell layer and 5.43 in lamina propria, while in the samples of health control those were 0.26 and 0.18 (P

Objective To screen the optimal parameters of rectal probe electrostimulation (RPES) to release spasticity after spinal cord injury. Methods 10 patients with muscular tension more than 2 level of the modified Ashworth scale after spinal cord injury received the RPES in 9 parameters combinations from orthogonal array, every patient underwent a combination per day. Their muscular tension, clonus and reflex were recorded before and after each treatment. The varieties were analyzed with orthogonal design variance analysis. Results The optimal parameter for muscular tension was 10 mA, 3 /min, 15 min; for reflex: 10 mA, 4 /min, 10 min; for clonus: 40 mA, 2 /min, 15 min; spasm score: 10 mA, 2 /min, 15 min. Conclusion The stimulus intensity most affects the muscular tension, reflex and spasm score, and the frequency of stimulation most affects the clonus. The parameter components were separately for muscular tension, reflex, clonus and spasm score.

OBJECTIVETo discuss the results and significance of the detection of the CFTR gene mutation in azoospermia patients with congenital unilateral absence of the vas deferens (CUAVD).

METHODSWe collected peripheral blood samples from 6 azoospermia patients with CUAVD for detection of the CFTR gene mutations and single nucleotide polymorphisms. We analyzed the genome sequences of the CFTR gene in comparison with the website of the UCSC Genome Browser on Human Dec. 2013 Assembly.

RESULTSMissense mutation of c. 592G > C in exon 6 was found in 1 of the 6 azoospermia patients with CUAVD and splicing mutation of c. 1210-12T[5] was observed in the noncoding region before exon 10 in 2 of the patients, both with the V470 haplotype in exon 11.

CONCLUSIONMutations of the CFTR gene can be detected in azoospermia patients with CUAVD and the detection of the CFTR gene mutation is necessary for these patients.

Objective To establish a new method for determination of resorcinol in waste water. Methods The chemical luminescent reaction of KMnO4 and resorcinol in acid solution was studied by flow injection analysis. The related factors affecting chemical luminescent intensity were explored. The method for determination of resorcinol was established by flow injection analysis with chemical luminescence detection. Results The detection limit and linear range were 0.06?g/ml and 0.2-80 ?g/ml respectively. The relative standard deviation of 1.3% was obtained by 11 parallel determinations of 4.0?g/ml resorcinol. Conclusion This method was satisfactorily applied to determination of resorcinol in waste water.
