Two regression models, based on panel data over the period of 2000-2011, are built and used to analyze what factors determine China's exports of primary and semi-finished products of traditional Chinese medicine to ASEAN. The results indicate that, China GDP, the ratio of ASEAN to China GDP per capita, average export price, the ratio of state-owned assets to total assets, have a significant positive influence on the export volumes of primary products of Chinese medicine. At the same time, RMB appreciation, the ratio of three kinds of foreign-invested assets to total assets, China-ASEAN Early Harvest Program, ASEAN-China Free Trade Area have a significant negative influence. In respect of the export volumes of semi-finished products of Chinese medicine, the significant influential factors are ASEAN GDP and the ratio of ASEAN to China GDP per capita. The former is positive and the latter is negative. In order to optimize the commodity composition of experts, it is needed to increase export volumes of both primary and semi-finished products of Chinese medicine. According to the analysis above, some proposals are put forward, such as, improving the performance of foreign capital, playing an exemplary and leading role in technological innovation by state-owned enterprises, taking advantage of bargaining power of suppliers, increasing outward foreign direct investment.

ObjectiveTo analyze Echinococcus infection in definitive and intermediate hosts in different zones of Qinghai plateau,Qinghai southern plateau,Qilian mountain-Hehuang valley and Chaidamu basin,and to provideascientificbasisfor developing controlstrategiesagainstEchinococcosisinfection. Methods Echinococcosis infection in definitive hosts,dogs and foxes,was identified by morphological observation; in domesticated and wild intermediate host animals was identified by anatomy and pathology; some of the suspected samples were further identified by molecular biological methods.ResultsStray dogs in different zones of Qinghai plateau were infected with Echinococcus granulosus,the infection rates were 38.71％(300/775),49.60％(124/250),and 9.76％(4/41 ) in Qinghai southem plateau,Qilian mountain-Hehuang valley and Chaidamu basin,respectively,and the difference was statistically significant(x2 =25.72,P ＜ 0.01 ).in addition,only Qinghai southern plateau dogs were infected with Echinococcus multiloularis,and the infection rate was 16.04％(98/611).The infection rates of fox with Echinococcus multilocularis were 22.89％(38/166) and 30.77％(12/39) in Qinghai southern plateau and Qilian mountain-Hehuang valley,respectively,and wolves were also found to be infected with Echinococcus granulosus in the same areas.The infection rates of domesticated sheep,yaks,goats and pigs with Echinococcosis were significantly different statistically in those different areas(x2 =82.70,41.82,212.63,194.58,all P ＜ 0.01 ).The infection rates of sheep and yaks were higher[43.43％(5664/13 042),49.47％(2917/5896),52.99％ (887/1674),42.18％ (779/1847),50.70％ (1049/2069),52.90％ (685/1295) ] in three areas.The infection rates of goats and pigs [3.26％ (7/215),0.00％ (0/108)] in Qinghai southern plateau were lower than that of other two areas[ 19.51％(119/610),26.91％(43/1598),47.91％(343/716),21.91％(71/324)].The infection rates of Ochotona curzoniae with Echinococcosis were 6.21％ (243/3910),1.80％ (3/167) and 0.00％ (0/199) in Qinghai southern plateau,Qilian mountain-Hehuang valley and Chaidamu basin,respectively,and the difference was statistically significant (x2 =18.50,P ＜ 0.01 ).Moreover,wild intermediate hosts of Echinococcosis,such as Microtus fuscus,Lepus oiostolus,Pseudois nayaur,Procapra picticaudata,and Prodorcas gutturosa were found to be infected only in Qinghai southern plateau.ConclusionsHuman is faced with a threat of Echinococcosis infection from various definitive hosts in different zones of Qinghai plateau.And stray dogs are the most crucial factor.The life-cycles of Echinococcus are very complicated in Qinghai plateau.Qinghai plateau is a key area in prevention and control of Echinococcosis infection in China.

To effectively guarantee quality of randomized controlld trial (RCT) of acupuncture and develop reasonable content and checklist of on-site quality control, influencing factors on quality of acupuncture RCT are analyzed and scientificity of quality control content and feasibility of on-site manipulation are put into overall consideration. Based on content and checklist of on-site quality control in National 11th Five-Year Plan Project Optimization of Comprehensive Treatment Plan for TCM in Prevention and Treatment of Serious Disease and Clinical Assessment on Generic Technology and Quality Control Research, it is proposed that on-site quality control of acupuncture RCT should be conducted with PICOST (patient, intervention, comparison, out come, site and time) as core, especially on quality control of interveners' skills and outcome assessment of blinding, and checklist of on-site quality control is developed to provide references for undertaking groups of the project.

OBJECTIVETo observe the effects of taurine on hemorheology and oxidative stress of diabetic rats.

METHODS40 rats were divided into control group, diabetes group and treatment group at random. Diabetic model was reproduced by intraperitoneal injection of streptozotocin. After having been treated with taurine for 8 weeks, glycosylated hemoglobin (HbA1c) and the serum contents of glucose, superoxide dismutase(SOD), malondialdehyde (MDA) were measured. The changes of hemorheology in different groups were detected respectively.

RESULTSCompared with control group, the content of glucose, MDA and HbA1c in diabetic rats was increased, the activity of SOD was decreased, the levels of whole blood viscosity and the aggregation index of red blood cells and hematocrit were increased and RBC deformability index was decreased in diabetic rats. Moreover, taurine was able to apparently reduce high blood glucose and HbA1c (P < 0.05), markedly elevated the activity of SOD, lowered the content of MDA (P < 0.01); and taurine also could significantly reduce the levels of whole blood viscosity and the aggregation index of red blood cells and hematocrit in the meanwhile, and increase RBC deformability index (P < 0.05 or P < 0.01).

CONCLUSIONTaurine could enhance the ability of oxidation resistance, improve blood rheology property in diabetic rats, at the same time it could be beneficial to prevent and cure the development of diabetic blood vessel complication.

OBJECTIVEDiffuse panbronchiolitis (DPB) is a chronic progressive disease of the lower respiratory tract, which is prevalent in Asian population. So far, many DPB cases have been found in adults in China. To our knowledge, no pediatric DPB case has ever been reported in China. We describe the first pediatric DPB case in Chinese literature and the second case in the English-language literature.

METHODThe clinical manifestations, characteristic imaging and histological features of this DPB case were summarized.

RESULTSThe patient was a 13-year old girl complained of chronic productive cough with wheezing. Chest auscultation revealed fine moist rales and wheezing over both lung fields. The chest X-ray showed small nodules and reticular opacities in left lower lobe. High-resolution thorax computerized tomography (HRCT) demonstrated bilateral diffuse small centrilobuler nodules and bronchial wall thickening or bronchiectasis in some parts of the lungs. Histopathological examination of transbronchial biopsy specimen revealed lymphocytes and foamy histocytes infiltrated in the walls of bronchi, respiratory bronchioles and adjacent alveoli. Lymphoid follicles were present around some bronchi. Sinus radiographs revealed sinusitis. Lung function studies showed obstruction and restriction. PaO2 was 65 mm Hg. The diagnosis of DPB was made according to the current diagnostic criteria. Low-dose erythromycin [5 - 10 mg/(kg.d)] was effective.

CONCLUSIONDPB could occur in children in China. The major diagnostic clues may include the following: (1) persistent cough, sputum, and dyspnea; (2) coexistent chronic sinusitis; (3) bilateral diffuse small nodular opacities on HRCT. Low-dose erythromycin was effective in treatment of the case with DPB.

OBJECTIVETo improve the recognition of Fechtner syndrome.

METHODSThe clinical and laboratory data and family survey of a patient with Fechtner's syndrom was reported.

RESULTS AND CONCLUSIONGiant platelets, thrombocytopenia and characteristic granulocyte inclusion bodies (Döhle-like bodies) were found in both peripheral blood and bone marrow smears of the patient. Clinically the patient had renal damage, nervous deafness, and vitreous lesions. There was a family genetic tendency on family survey the diagnosis of Fechtner syndrome is established.
