Objective To explore the clinical effects of aminophylline on bronchiolitis in children.Methods One hundred and twen-ty-eight children with bronchiolitis in our hospital were randomly divided into the experiment and treated control group,in the meantime,and divided into the severe and mild group according to their condition.The children in control group were treated with traditional methods,in experiment group were treated with aminophylline(2 mg/kg,every day one time),as well as used traditional methods.All patients in 2 groups were checked by volume (VT), inhale time and exhale time ratio (Ti/tE),time to peak expiratory flow and expiratory time ratio(tPTEF/Te),time to peak expiratory flow to total expiratory time and volume ratio(vPTEF/vE) respectively. Meanwhile pulmonary function,alkyla-denine glycosylase in trachea secretion,IL-8,cytotaxonomy in trachea secretion on time,after the third day and the 7th day.Their curative effects were evaluated.All parameters were analyzed by statistical methods.Results Cytotaxonomy of the patients in the experiment were more improved than that of control group(P

Objective:To study the characteristics of stress faced by and coping style of patients with tempormandibular disorder (TMD). Methods: Thirty patients with TMD and thirty normal controls participated in the study. All subjects were asked to answer the psychological rating questionnaires, including life events scale (LES) and trait coping style questionnaire (TCSQ). The muscle electricity were also measured when the subjects were exposed to an acute stress situation. Results: There were significant difference in LES, TCSQ and response to acute stress. Patients with TMD encountered more life events than normal controls. They also used more negative coping styles and less positive ones. The responses evoked by acute stress situation were more intense and lasted longer than normal controls. Conclusion: Stressful life events, coping style and responses evoked by acute stress may play a significant role in etiology of TMD.

OBJECTIVETo screen the proteins under regulation by the candidate tumor suppressor gene CCDC19 using proteomics technology in nasopharyngeal carcinoma (NPC).

METHODSThe cellular proteins were extracted from 3D8 NPC cells with CCDC19 overexpression and the control C6 NPC cells. Two-dimensional (2D) gel electrophoresis was employed to compare the protein expression profiles between these two cells, and the differential proteins were identified using peptide mass fingerprinting and database searching. Real-time PCR and Western blotting were used to validate the expression levels of the differential proteins.

RESULTSMatrix-assisted laser desorption/time of flight showed that 3 differential proteins, namely FASN, CTSD and PGK1, were down-regulated by -3.28, -1.64, and -6.97 folds, respectively, which were confirmed by real-time PCR and Western blotting.

CONCLUSIONFASN, CTSD and PGK1 are probably the target proteins regulated by CCDC19 in NPC.

Objective To screen potential genes associated with drug resistance and multidrug resistance. Methods Microarray with 8000 genes was used to detect the different expression of 5-8F cells and 6-10B cells. Subsquently, genes of drug resistance and multidrug resistance were screened by MILANO online programme. Semiquantitative RT-PCR was utilized to confirmed the reliability of differentially expressed genes. Results 283 genes were identified the differential expression. Of these, 85 genes were shown to be upregulated and 98 downregulated. After the analysis of MILANO, 4 genes including UGT1A9 (15.85 folds),MVP(6.77 folds), CAV1(2.49 folds) and HIF1A(2.67 folds) with higher expression in 5-8F cells were found to be likely associated with drug resistance and multidrug resistance. Subsquently, semiquantitative RT-PCR confirmed the reliability of differential expression of these 4 genes. Conclusion Differentially expressed genes shown in NPC 5-8F cells compared to 6-10B cells with the identification of online MILANO program analysis are likely associated with drug resistance and mnltidrug resistance of NPC cells with the ability of metastasis.

In order to provide a scientific basis for the establishment of a Daphnes Cortex medicinal material fungus library and the screening of endophytic fungi that promote the growth of Daphnes Cortex and increase the content of daphnetin, we used Illumina high-throughput testing technology to analyze 9 Daphnes Cortex samples from Gansu and Shanxi provinces. A total of 632 766 valid sequences were obtained, including 348 OTUs, 4 phyla, 20 classes, 48 orders, 108 families, 154 genera, and 208 species. The sum of the first 3 fungal genera account for more than 65% of the total abundance, with the highest reaching 98.4%. Alternaria and Phoma are the main genuses of Daphne giraldii Nitsche, and Altemaria is the dominant genus. The endophytic fungi community of Daphnes Cortex is rich in diversity, and the order of fungal diversity in different producing areas is: Gangu County > Wutai County > Tanchang County.

OBJECTIVETo construct a lentiviral vector carrying human NESG1-EGFP gene and observe its expression in 293FT cells.

METHODSThe CDS region of NESG1 gene was amplified from a plasmid containing the full-length NESG1 sequence and cloned into the lentiviral vector pGC-FU-EGFP by restriction endonuclease AgeI digestion and T(4) DNA ligase ligation. After transformation into competent E. coli cells, the candidate clones were identified by PCR and sequencing. The recombinant plasmid and the two packaging plasmids were co-transfected into human embryonic kidney cell line 293FT cells by lipofectamine 2000 to produce the lentiviral particles, and the viral titer was determined. The 293FT cells were infected by the lentiviral particles obtained and the transfection efficiency was assessed under fluorescent microscope. Western blotting was used to detect the expression of NESG1 protein in the transfected cells.

RESULTSThe lentiviral vector pGC-FU-NESG1-EGFP for NESG1 gene was constructed successfully. Strong green fluorescence was observed in 293FT cells under fluorescent microscope after co-transfection of the cells with the 3 plasmids of lentiviral vector. The virus in the supernatant reached a titer of 2×10(7) TU/ml. The transfection efficiency of the collected virus exceeded 90% in 293FT cells with a multiplicity of infection of 1. Western blotting identified the presence of NESG1 expression in the transfected 293FT cells.

CONCLUSIONThe lentiviral vector for NESG1 has been successfully constructed with a high yield of lentivirus, which facilitate further investigation of the roles of NESG1 gene in the development and progression of nasopharyngeal carcinoma.

OBJECTIVETo explore the expression of CASP8 and its clinical significance in nasopharyngeal carcinoma (NPC).

METHODSThe differentially expressed genes between pooled NPC tissues and non-cancerous nasopharyngeal (NP) tissues were screened using 8 microarrays. Real-time PCR and immunohistochemistry were used to validate the detection results of CASP8 expression in NPC, and the correlation of CASP8 expression to the clinical characteristics was analyzed in the NPC cases.

RESULTSReal-time PCR confirmed a reduced expression of CASP8 mRNA level in NPC tissues (P<0.0001), which was consistent with the microarray data. Immunohistochemistry indicated that CASP8 protein expression was also significantly down-regulated in NPC tissue compared to that in the non-cancerous nasopharyngeal tissues (P=0.02). The reduction of CASP8 expression was inversely correlated to lymph node metastasis (P=0.002) and the clinical stages (P=0.026) of NPC.

CONCLUSIONDecreased CASP8 expression is an unfavorable factor that promotes the development and progression of NPC.

Medical imaging is an interdisciplinary subject closely related to clinical and pathological subject. Its clinical reading skills' training has become the focus of postgraduate teaching. In the process of clinical teaching, the interactive reading mode of problem-based learning (PBL) combined with multi-disci-plinary team (MDT) was introduced into clinical reading meeting. The tutors chose the reading cases proved by pathology; designed in-depth issues step by step for execution of PBL teaching; guided postgraduates to delineate imaging signs and propose the diagnostic results, evidences and differential diagnoses according to the step from localizing to qualitative and then to pathological diagnosis;then guided postgraduates to attend in-depth case analysis of MDT and analyze the correlation or inconsistency between the imaging diagnosis and clinical and pathological diagnosis; exercise document retrieval and verbalization, multimedia design, and writing level of the records of the reading cases and papers. The interactive reading mode of PBL com-bined with MDT has achieved significant effects, which is worthy of further exploration and promotion.
