Gene knockout by ZFNs (zinc-finger nucleases) is efficient and specific, and successfully applied in more than 10 organisms. Currently, it is unclear whether this technology can be used for knocking-out enhanced green fluorescent protein (EGFP) gene in transgenic goats. Here we constructed and used ZFN-coding plasmids to produce genetic knockouts in the cells of cloned fetus produced from donor cells by microinjection of EGFP gene. Following introduced plasmids into caprine primary cultured fetus fibroblasts by electroporation, targeting of a transgene resulted in sequence mutation. Using the flow cytometric analysis, we confirmed the disappearance of EGFP expression in treated cells. Sequence from PCR products corresponding to targeted site showed that insertion of a G into the exon of EGFP resulted in frame shift mutation. These results suggest that ZFN-mediated gene targeting can apply to caprine fetus fibroblasts, which may open a unique avenue toward the creation of gene knockout goats combining with somatic cell nuclear transfer.

The characteristics of onset time of cough variant asthma (CVA) match with the human hypnagogic and arousal time nodes, which are also in accordance with the time of defensive qi entering yin and exiting yang of human body. Reviewing the generation and physiological function of defensive qi, we hold that the onset of CVA is related to the lung, the spleen and the kidney. Deficiency of the three viscera leads to defi ciency of defensive qi defi ciency, and blockade of the circulation pathway of defensive qi on body surface, thus interaction of the two factors results in the special time nods of CVA’s onset, which is also the basic pathomechenism of CVA.

Background and purpose: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new minimally invasive method in the dignosis for mediastinal lymph nodes. This study was to evaluate the diagnostic yield of EBUS-TBNA for mediastinal lymph nodes. Methods: Twenty patients with mediastinal lymph nodes found by CT underwent the dignosis by EBUS-TBNA form April 1st 2009 to July 16th 2009. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA were evaluated. Results: Twenty patients with 37 lymph node groups were studied. Overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EBUS-TBNA for diagnostic were 84.62%, 100%, 100%, 77.78% and 90.00%, respectively. The diagnostic accuracy for cancer was 100%. The operation time was 11.9min per group in average with no serious complication. The median length of hospital stay was 1 (range from 1 to 17 days) day after operation. There were significant differences in the average operation time between the first three patients and the others (36.25 min vs. 7.76 min; z=3.247, P=0.001). Conclusion: Endobronchial ultrasound-guided transbronchial needle aspiration proved to be a safe procedure with a high yield for the diagnosis of mediastinal lymph nodes.

Objective To explore the difference between T cells in the synovial fluid and peripheral blood in patients with rheumatoid arthritis(RA). Method Samples from 22 patients were studied. The differentiation and activation markers expressed on T cell surface were detected by immunofluorscence using flow cytometer. The specific proliferation of collagen Ⅱ and heat shock protein 70 was analyzed using standard 3H-TdR incorporation method. Restricted V beta usage of these T cell was analyzed by semi-quantitied RT-PCR. Results The majority of the T cell subsets in the synovial fluid were demonstrated to be CD4 and CD8 positive cells in which (40?10)% were CD4 positive and (36?16)% were CD8 T cells respectively. The ratio between CD4 and CD8 was much lower than that found in the PBL of RA patients. The percentage of CD3+/CD25+ T cells was (16?6)%. The specific proliferation of collagen Ⅱ and HSP70 to CD3+/CD25+ T cell was higher than that of CD3+/CD25+ negative T cells. The T cell receptor expressed on the T cells from both peripheral blood and synovial fluid were tested for ?? TCR (70?26)%. However, the T cells in the synovial fluid showed V?14,16 and 17 restriction. Conclusion The data here reported indicates that T cell subsets in the synovial fluid and peripheral blood circulation in patients with rheumatoid arthritis are different. The T cells in the synovial fluid demonstrates more activation and higher reactivation to collagen Ⅱ and HSP70. The TCR of T cells showes V?14,16 and 17 restriction.

Objective:To analyze the electrophysiological characteristics and influencing factors of peripheral neuropathy in Parkinson's disease(PD)patients.Methods:Totally 68 PD patients and 30 controls were selected for neuroelectrophysiological evaluation, including items such as limb motor nerve terminal latency(LP)and amplitude and sensory nerve conduction velocity(SCV)and amplitude.Age, sex, serum folate, vitamin B 12, homocysteine and hemoglobin levels were also recorded for the two groups.The Hoehn-Yahr scale was used to assess patients and levodopa daily doses and levodopa equivalent daily doses were calculated.According to the criteria for neuroelectrophysiological abnormalities, 31 PD patients were found to have peripheral neuropathy and 37 PD patients did not have peripheral neuropathy. Results:In PD patients, a total of 952 peripheral nerves were examined, with 21.7% having motor nerve involvement(118/544)and 72.8%(297/of 408)having sensory nerve involvement.In the control group, a total of 420 peripheral nerves were examined, with 4.2%(10/240)having motor nerve involvement and 26.1%(47/180)having sensory nerve involvement.Compared with the control group, the wave amplitudes of motor nerve terminals were reduced in the PD group for the ulnar nerve( t=2.172/2.345, right/left), median nerve( t=2.104/2.543, right/left), and tibial nerve( t=2.340/2.444, right/left)(all P<0.05); compared with the control group, the wave amplitudes of sensory nerve terminals of the ulnar nerve( Z=3.535/3.439, right/ left), median nerve( Z=3.076/2.937, right/left), and peroneal nerve( Z=2.795/2.795, right/left)were all reduced in the PD group(all P<0.05); compared with the control group, sensory conduction velocities of the ulnar nerve( t=2.326/2.487, right/left), median nerve( t=3.269/2.386, right/left), and peroneal nerve( t=2.551/2.418, right/left)were prolonged(all P<0.05). The rate of abnormalities with the sensory nerve terminal wave amplitude( χ2=149.814, P<0.001)was higher than that of abnormalities with motor nerve terminal wave amplitude in PD patients; the rate of abnormalities with the sensory nerve terminal wave amplitude( χ2=58.364, P<0.001)was higher than that of abnormalities with sensory conduction velocities.Logistic regression analysis showed that increased folic acid( OR=0.825, 95% CI: 0.637-0.990)and vitamin B 12( OR=0.996, 95% CI: 0.991-1.000)were protective factors for PD peripheral neuropathy; H-Y score, levodopa daily dose( OR=1.009, 95% CI: 1.003-1.015), and increased homocysteine( OR=1.151, 95% CI: 1.041-1.273)were risk factors for PD peripheral neuropathy.After excluding confounding factors, H-Y classification( OR=3.213, 95% CI: 1.342-7.713)remained an independent risk factor for peripheral nerve injury in PD patients. Conclusions:In PD patients with peripheral neuropathy, both motor nerves and sensory nerves are involved, sensory nerves are more significantly involved, and axonal damage is more important than myelin loss; increased H-Y classification is an independent risk factor for peripheral nerve injury in PD patients.
