BACKGROUND: MyoD gene is one of family members of muscle transcription factors. Transfection MyoD gene can switch on the procedure of differentiation of muscles, and transit non-muscle cells into muscle cells.The MyoD gene only expresses in skeletal muscles. Based on the same contractive structure in myocardial cells and skeletal muscle cells, it is imagined that the conversion from exogenous MyoD gene-induced fibroblast in local myocardium into skeletal muscle cells that had contractive function may become another method in the treatment of congestive heart failure on clinic.OBJECTIVE: To construct and identify a recombinant adenoviral vector carrying MyoD gene for further studies on the recovery function of MyoD gene in myocardial injury.DESIGN: Single sample experiment.SETTING: Department of Cardiology, First Affiliated Hospital, Nanjing Medical University.MATERIALS: The experiment was conducted at the Laboratory of Microbiology and Immunology, Nanjing Medical University between September 2004 and September 2005. MyoD gene and non-replicating form expressive vector of adenovirus were taken as research materials.METHODS: MyoD cDNA fragments were extracted from plasmids pEMSV-MyoD with polymerase chain reaction (PCR), and PCR was used to clone the whole-length gene of MyoD. After adding CACC sequence at 5' end, MyoD gene was cloned by orient topology into transfer ventor, pENTR/D-TOPO. Objective gene was transferred into adenoviral expression vector DNA via pENTR/D-TOPO vector. The recombinant adenoviral vectors transfected into HEK293A cells by using lipofectamine were packaged and amplified.MAIN OUTCOME MEASURES: Evaluation of PCR and DNA sequencing were used for confirming the size of segment and correctness of rank of MyoD cDNA and detecting the titre of virus.RESULTS: MyoD recombinant adenovirus contained target segment with precise length confirmed by PCR and DNA sequence that was correct. The titre of virus was 1.3×1011 pfu/mL.CONCLUSION: The recombinant adenoviral vector carrying MyoD gene is constructed successfully.

Objective To identify the expression of PTPRD in esophageal squamous cell carcinoma (ESCC)and analyze its correlation with pathological features and patient survival.Methods Immunohistochemistry analysis was applied to detect the expression level and location of PTPRD in 236 patients with ESCC.Clinical and pathological features were collected and a 5 years’follow-up after surgery were performed.Results Statistic analysis showed that expression of PTPRD in ESCC was lower than in normal esophageal epithelial cells (22.0% vs 57.2%,P =0.000).The expression of PTPRD was correla-ted to the differentiation grade,depth of tumor invasion and lymph nodes metastasis.The expression of PTPRD was higher in group with well differentiation,less invasion depth and no lymph node metastasis (P =0.013,0.025,0.019).The expres-sion of PTPRD was not correlated to age or gender (P =0.170,0.787).The survival analysis showed that thegroup with more PTPRD expression had better prognosis.Conclusion PTPRD was correlated to progression and prognosis of ESCC.It may be a new potential tumor suppressor gene of ESCC,and its expression level might may a useful marker for predicting prognosis for ESCC patients.

Self-biting is a chronic disease, which cause wound to take effect on mink growth and pelt quality. In this study, we firstly adopted RAPD (random amplification polymorphism DNA) technique based on the reproducible 26 polymorphism primers screened from 100 random primers to analyze hereditary constitution of the samples from healthy minks and self-biting minks, respectively, at molecular level to aim to discuss the causes of self-biting. The results showed that 29 straps showed polymorphism among amplified 105 straps, of which the polymorphism rate is 27.62%. Between healthy and sick mink groups, the amplified DNA fragment through different primers indicated different distribution frequency. The similarity coefficient of mink groups is 0.8471 and genetic distance (variation) index is 0.1529. Through primer S356 (whose sequence is CTGCTTAGGG), we amplified different straps between healthy and sick mink. The amplified 1000 bp DNA fragment in the sick mink groups can preliminarily serve as molecular genetic label to distinguish from healthy and sick mink groups to gradually remove the mink individual of self-biting, achieve to purify mink groups and reduce economy loss of mink breeding industry. This work provide theoretical basis for further study on molecular breeding and disease prevention of mink.

PURPOSE: Chronic cough in allergic rhinitis (AR) patients is common with multiple etiologies including cough variant asthma (CVA), non-asthmatic eosinophilic bronchitis (NAEB), gastroesophageal reflux-related cough (GERC), and upper airway cough syndrome (UACS). Practical indicators that distinguish these categories are lacking. We aimed to explore the diagnostic value of the fraction of exhaled nitric oxide (FeNO) and forced expiratory flow at 25% and 75% of pulmonary volume (FEF(25–75)) in specifically identifying CVA and NAEB in these patients. METHODS: Consecutive AR patients with chronic cough were screened and underwent induced sputum, FeNO, nasal nitric oxide, spirometry, and methacholine bronchial provocation testing. All patients also completed gastroesophageal reflux disease questionnaires. RESULTS: Among 1,680 AR patients, 324 (19.3%) were identified with chronic cough, of whom 316 (97.5%) underwent etiology analyses. Overall, 87 (27.5%) patients had chronic cough caused by NAEB, 78 (24.7%) by CVA, 16 (5.1%) by GERC, and 81 (25.6%) by UACS. Patients with either NAEB or CVA (n = 165, in total) were further assigned to a common group designated as CVA/NAEB, because they both responded to corticosteroid therapy. Receiver operating characteristic curves of FeNO revealed obvious differences among CVA, NAEB, and CVA/NAEB (area under the curve = 0.855, 0.699, and 0.923, respectively). The cutoff values of FeNO at 43.5 and 32.5 ppb were shown to best differentiate CVA and CVA/NAEB, respectively. FEF(25–75) was significantly lower in patients with CVA than in those with other causes. A FEF(25–75) value of 74.6% showed good sensitivity and specificity for identifying patients with CVA. CONCLUSIONS: NAEB, CVA, and UACS are common causes of chronic cough in patients with AR. FeNO can first be used to discriminate patients with CVA/NAEB, then FEF(25–75) (or combined with FeNO) can further discriminate patients with CVA from those with CVA/NAEB.
