Journal of Geriatric Cardiology 2016年第11期13卷 894-898页

作者： Ji-li YUN xiao-ying li Medical School of Chinese PLA General Hospital Beijing China Department of Geriatric Cardiology Chinese PLA General Hospital Beijing China

Objectives To investigate the prevalence and characteristics of pulmonary embolism （PE） at autopsy in a Chinese general hospital over a period of 10 years, and to evaluate the antemortem achievement of the prophylaxis, diagnosis, and treatment of PE. Methods All medical records of deaths from the West Branch of the Chinese People＇s liberation Army （PLA） General Hospital were retrospectively re- viewed, for the period of January 1, 2006 to December 31, 2015. Cases in which autopsies had been performed were identified and further analyzed. The numbers and detailed characteristics of patients who had PEs were noted. Prophylactic measures, along with diagnosis and treatment of PE, were recorded, if performed. Results During the 10-year period, 1057 patients died in the study hospital and 278 necrop- sies were performed （autopsy rate： 26.3%）. Nine patients were found to have PE （3.2%）, and in seven of these patients （2.5%）, the PE was considered to be fatal. Embolisms were found in the trunk and bilateral main branches of the pulmonary artery tree in all seven of the fatal PE cases. Right intracardiac thrombosis was detected in five of the nine PE patients （55.6%）. All patients with PE had been hospitalized in medical departments, and only one had undergone surgery during hospitalization. Antemortem prophylaxis was performed in two of the nine PE cases （22.2%）. None of the 9 patients had received a clinical diagnosis of PE before death. Conclusions The incidence of and death rate associated with PE may vary among different races and regions. Continuous monitoring of PE by means of necropsy in certain representative medical institutions is necessary.

Variation in the Coat Protein Gene of Papaya ringspot Virus Isolates from Multiple Locations of China

Journal of Integrative Plant Biology 2007年第7期49卷 1062-1069页

作者： Jun-Ya Wei De-Bing liu xiao-ying li Peng Zhou State Key Laboratory for Tropical Crops Biotechnology Institute of Tropical Biology Science China Academy of Tropical Agricultural Science Haikou 571101 China Department of Horticulture South China University of Tropical Agriculture Danzhou 571737 China

The potyvirus Papaya ringspot virus （PRSV） is an important pathogen of papaya that causes severe losses in economic crops for papaya production globally. The coat protein （CP） genes of five PRSV isolates originating from different locations in China were cloned and sequenced. The CP-coding region varied in size from 864-873 nucleotides, encoding proteins of 288-291 amino acids. The five Chinese isolates of PRSV have been characterized as papaya-infecting （PRSV-P）. The CP sequences of the Chinese isolates were compared with those of previously published PRSV isolates originating from different countries at amino acid levels. A number of KE repeat boxes in the N terminus of the PRSV-CP were found in all Chinese isolates. The phylogenetic branching pattern revealed that there was certain extended grouping between geographic locations, and the Asian type probably represents the oldest population of PRSV. The information of CP genes will be useful in designing and developing durable virus resistant-PRSV transgenic papaya in China. Meanwhile broad-spectrum-virus resistant, strongly resistant-PRSV and good safe papaya lines are required.

Background Previous studies showed that overexpression of sarco-endoplasmic retieulum calcium ATPase （SERCA2a） in a variety of heart failure （HF） models was associated with greatly enhanced cardiac performance. However, it still undefined the effect of SERCA2a overexpression on the systemic inflammatory response and neuro-hormonal factors. Methods A rapid right ventricular pacing model of experimental HF was used in beagles. Then the animals underwent recombinant adeno-associated vires 1 （rAAV1） mediated gene trans- fection by direct intra-myocardium injection. HF animals were randomized to receive the SERCA2a gene, enhanced green fluorescent protein （control） gene, or equivalent phosphate buffered saline. Thirty days after gene delivery, the cardiac function was evaluated by echocardiographic testing. The protein level of SERCA2a was measured by western blotting. The proteomic analysis of left ventricular （LV） sample was determined using two-dimensional （2-D） gel el^ctrophoresis and MALDI-TOF-MS. The serum levels of the systemic inflammatory and neuro-hormonal factors were assayed using radioimmunoassay kits. Results The cardiac function improved after SERCA- 2a gene transfer due to the significantly increased SERCA2a protein level. Beagles treated with SERCA2a had significantly decreased serum levels of the inflammatory markers （interleukin-6 and tumor necrosis factor-a） and neuro-hormonal factors （brain natriuretic peptide, endothelin-1 and angiotensin II） compared with HF animals. The myocardial proteomic analysis showed that haptoglobin heavy chain, heat shock protein （alpha-crystallin-related, B6） were down-regulated, and galectin-1 was up-regulated in SERCA2a group compared with HF group, companied by up-regulated contractile proteins and NADH dehydrogenase. Conclusions These findings demonstrate that regional intramyocardial injections of rAAV 1-SERCA2a vectors may improve global LV function, correlating with reverse activation of the systemic inflammatory,
