Purpose To evaluate the value of imaging on the diagnosis and treatment of human-infected H10N8 virus. Materials and Methods The chest X-ray and CT features of one case of human infected H10N8 virus were retrospectively studied. Results A 73-year-old female patient was admitted to the third affiliated hospital of Nanchang University on November 30, 2013 due to cough, sputum for 3 days and fever for 1 day. The patient was diagnosed with severe pulmonary infection and underwent chest CT on December 1, which showed large opacities with air bronchograms were in the lower lobe of her right lung and ground-glass exudative lesions in the lower lobe of the left lung;the next 24 h, 48 h and 72 h review tracking chest X-ray showed the chest lesions developed rapidly which involved more lobes with more areas, integration of lesions and plenty of pleural effusion in a very short time. This was a typical white lung sign of acute respiratory distress syndrome. The patient died later on December 6, which was reported as the case of human-infected avian influenza (H10N8 virus) by Chinese Center for Disease Control and Prevention. Conclusion The chest imaging features found in human infected H10N8 virus present as progressive opacities and exudative lesions.

Objective To explore mRNA and protein expression of PAl-1 in kidney tissue of mice with IgA nephropathy (IgAN) and the effects of YiShen Decoction. Methods The IgAN model was built by the method of oral intake of bovine serum albumin(BSA)together with the injection of staphylococcus enterotoxin B(SEB)through caudal vein. The mRNA expression of PAI-1 was measured by fluorescent quantitative polymerase chain reaction (FQ-PER)and the expression of PAI-1 protein was measured by immunohistochemistry. Results No significant difference of mRNA and protein expression of PAI-1 was found between the low concentration and high concentration Yishen Decoction group. But the secretion and mRNA expression of PAI-1 in the low and hiigh concentration Yishen Decoction group was decreased more than that in the IgAN model group. Conclusion The abnormal expression of PAI-1 mRNA and protein played an important role in the onset and development of IgAN. The TCM Yishen Decoction could reduce the abnormal expression of the mRNA and protein of PAI-1 in kidney tissue of mice with IgA nephropathy.

In the post-genomic era, with the accomplishment of the sequence mapping of human genome, one of the most important tasks for life science is the explanation and identification of human genome, that is, about 1/3 genes of human genome and their functions need further revealment and verification on the level of protein. In the field of functional proteomics, the human disease proteomics shows great potential in the discovery of new molecular targets and biomarkers for medicine and biopharmacy. In this article, we have made a concise discussion on the current status, existing problems and future development in the research of human disease proteomics both in and out of China.

BACKGROUND:Magnetic resonance diffusion tensor imaging can display the dispersion changes of peripheral nerve injury and be used to conduct quantitative research, so it has good application prospects in displaying the nerve injury and regeneration. OBJECTIVE:To investigate the possibility of magnetic resonance diffusion tensor imaging of rabbit acute sciatic nerve traction injury, and to figure out the value of diffusion tensor parameters in the diagnosis of peripheral nerve injuries and to reveal the pathologic basis. METHODS:The right hind limb sciatic nerves of 32 New Zealand white rabbits were selected to make the regeneration and repair models, the left hind limb nerves as the sham-operation side. Diffusion tensor imaging examination of sciatic nerves were performed at 1 and 3 days, 1, 2, 3, 4, 6 and 8 weeks after operation with 1.5 T MRI. Fractional anisotropy and apparent diffusion coefficient were measured through diffusion tensor tracing
reconstruction, and then the pathological examination was performed. RESULTS AND CONCLUSION:Diffusion tensor imaging revealed only the proximal nerve, injured nerve as wel as the middle of the distal nerve at 1 day after traction injury. At 1 week, the nerve of distal portion appeared thinner and shorter fiber bundle. At 2-6 weeks after operation, the fiber bundle was increased and thickened. At 8 weeks after operation, the distal nerve fibers had nearly restored to the level before injury. There was significant difference in the fractional anisotropy value of traction portion and distal portions between traction injury and sham-operation group at 1 day-8 weeks after operation (P<0.05). While there was significant difference in the fractional anisotropy value of proximal traction portion between traction injury and sham-operation group 1 day-1 week after operation (P<0.05). There were no significant differences in the apparent diffusion coefficient values between traction injury and sham-operation group at 1 day-8 weeks after operation. Fal of fractional anisotropy value in the early stage of nerve traction injury was the result of myelin sheath broke down and axonal disintegrated;recovery of fractional anisotropy value resulted from myelin sheath proliferated and myelin sheath grew slowly to mature. Diffusion tensor tracing can show the abnormal change of the sciatic nerve with traction injury in rabbit clearly and early, and the measurement of fractional anisotropy value can be used as the sensitive method to monitor the degeneration and regeneration after nerve traction injury.

Objective To investigate the effects of early rehabilitative training program on patients with acute myocardial infarction(AMI).Methods One hundred and twenty-two patients with AMI were randomly divided into early rehabilitation group(n=62)and control group(n=60).In addition to routine treatment,patients in rehabilitation group received early rehabilitative training mainly by walking exercise for two weeks.Results There were no significant differences in ventricular arrhythmia(Lown≥Ⅲ), extension of infarction and heart rate variability(HRV)between the two groups(P＞0.05).Forty of 62 patients(64.5%)in rehabilitation group had their left ventricular ejection fraction(LVEF)more than or equal to 50% in the 3~(rd)～4~(th)week after admission,significantly higher than that in control group(45.0%, 27/60 ;P＜0.01 ).By the end of the 4~(th)week after admission,25.8% of the patients in rehabilitation group showed positive in treadmill test,significantly lower than that in control group(38.3%,P＜0.01). Occurrence of angina pectoris and reinfarction and fatality in rehabilitation group were significantly lower than those in control group(P＜0.05)during their hospitalization and follow-up period.Patients in rehabilitation group stayed at hospital for(16?3)days in average,significantly less than that in control group[(27?4) days],with statistically significant difference(P＜0.05).Conclusion Early rehabilitative training for patients with uncomplicated AMI is not only safe and feasible,but also useful in improvement for their prognosis and quality of life.

To study the protective mechanism of Danhong injection on brain microvascular endothelial cells (rBMECs) injured by hypoxic. In the experiment, primary suckling mouse's rBMECs cells were collected and identified with factor VIII to establish the 4 h injury model. Meanwhile, rBMECs were given Danhong injection (25, 50, 100 mL . L-1), and the superoxide dismutase (SOD) activity and the malonyldialdehyde (MDA) level were detected by the biochemical method. Cell MMP-9, ICAM-1 and P53 mRNA expression levels were detected by RT-PCR method. Changes in cells' microscopic structure were observed by transmission electron microscope. According to the results, primary rBMECs were notably injured by hypoxia. Compared with model group, Danhong injection (50, 100 mL . L-1) could remarkably resist the injury induced by hypoxic, increase intracellular SOD activity, decrease MDA level and significantly down-regulate ICAM-1, MMP-9 and P53 mRNA expressions. Danhong injection (100 mL . L-1) could protect the cells' normal morphology and microscopic structure, maintain the close intercellular junction, and inhibit the hypoxia-induced cell apoptosis. The results showed that Danhong injection plays a significant role in protecting rBMECs injured by hypoxia. Its mechanism may be related to the enhancement of cells' antioxidant capacity, the inhibition of inflammatory response and the cell apoptosis.
