Abstract: Schistosomiasis, an important zoonotic parasitic disease, is one of the six major tropical diseases identified by WHO, and also one of the most important parasitic diseases for prevention and control in China. After more than 70 years of efforts, the prevention and control of schistosomiasis in China has made great achievements, and the current epidemic of schistosomiasis in China has entered an extremely low epidemic state, but the distribution base of the only intermediate host of schistosomiasis, Oncomelania hupensis, is still large. For now, the techniques used to monitor schistosomiasis have shortcomings such as time-consuming, laborious and low sensitivity, which cannot meet the current needs of China. Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water or air) without isolating any target organisms, which is a complex mixture of genomic DNA and its degradation products from different organisms in the same environment. eDNA technology can reflect the community or species composition information in the ecosystem through DNA extraction and detection of environmental samples. Compared with traditional biological monitoring methods, eDNA technology has the advantages of high efficiency, high sensitivity and environmental friendliness. eDNA has been successfully used for the specific detection of Schistosoma mansoni, Schistosoma haematobium and Schistosoma japonicum. This paper reviews the current detection methods of eDNA, the application and technical limitations of eDNA technology in schistosomiasis monitoring, aiming to provide scientific reference for research in the field of schistosomiasis surveillance.

Objective To investigate the effect of prognostic factors and nursing care in of acute myocardial infarction(AMI)patients performed emergency percutaneous coronary intervention supported by IABP.Methods Twenty seven AMI patients treated with emergency PCI,supporting by intra-aortic balloon pump(IABP).We analyzed retrospectively elinical characters and situation of interventional treatment of the patients.Results Among 27 cases.there were 12 cases who were recovered,4 suffered congestive heart failure repeatedly.and ll died during the hospitalization.There was no difference in age,sex,the history of hypertension,diabetes and smoking,the site of infarction and ejection fraction of left ventficular.The prognosis was different in the patients with grade of Killip in cardiac function and no flow post PCI(P<0.05).Conclusions The grade of Killip and no flow post PCI were the effective factors for prognosis in Acute Myocardial patients with emergency PCI.

The LEAFY (LFY) homologous gene of Dendrobium moniliforme (L.) Sw. was cloned by new primers which were designed based on the conservative region of known sequences of orchid LEAFY gene. Partial LFY homologous gene was cloned by common PCR, then we got the complete LFY homologous gene Den LFY by Tail-PCR. The complete sequence of DenLFY gene was 3 575 bp which contained three exons and two introns. Using BLAST method, comparison analysis among the exon of LFY homologous gene indicted that the DenLFY gene had high identity with orchids LFY homologous, including the related fragment of PhalLFY (84%) in Phalaenopsis hybrid cultivar, LFY homologous gene in Oncidium (90%) and in other orchid (over 80%). Using MP analysis, Dendrobium is found to be the sister to Oncidium and Phalaenopsis. Homologous analysis demonstrated that the C-terminal amino acids were highly conserved. When the exons and introns were separately considered, exons and the sequence of amino acid were good markers for the function research of DenLFY gene. The second intron can be used in authentication research of Dendrobium based on the length polymorphism between Dendrobium moniliforme and Dendrobium officinale.

Objective To explore the inhabitants' knowledge about Keshan disease(KD) in endemic area in Heilongjiang Province and analyze its influencing factors. Methods Yongjin Village, a national KD monitoring site in Fanrong Township of Fuyu County in Heilongjiang Province,was selected as an investigating spot. Specially designed questionnaire was applied in the investigation, which included three aspects, demographical information (gender, age, educational level, etc.), KD-related knowledge survey (KD prevention measures including a healthy diet supplementing selenium, preventing microbial infection, inducers such as climate change, fatigue, cold, mental shock, overeating) and KD controlling measures (take prescribed medicine, dietetic regulation and regular exercise, etc.) Results Seventy-senven point six percent(272/352) knew the disease by the name in the endemic area, while only 29.7% (81/272)and 30.8% (84/272)were aware the preventive measures and inducers , respectively. The awareness rates of KD preventive measures and inducers among the KD patients were 6/17 and 9/17 respectively. The influencing factors of the awareness rate of KD name were gender, vocation and the state of education (χ2 value were 9.838,9.878,12.462, all P < 0.05). However, factors influencing the awareness rates of preventive measures were gender and the state of education(χ2 value were 7.400,20.251, both P < 0.05). Conclusions The awareness rates of KD preventive measures and inducers axe low in the endemic area. The major factors influencing the awareness rate of KD are gender and the educational degree.

OBJECTIVEKawasaki disease is an acute systemic vasculitis syndrome primarily affecting small and medium-sized arteries, with development of severe coronary artery lesion (CAL). CAL may induce myocardial infarction and sudden death. So it is very important to find CAL early. In this study the value of multislice spirral computed tomography (MSCT) was investigated to find CAL in patients with Kawasaki disease.

METHODSThirty-four patients with Kawasaki disease were examined respectively by using MSCT and two dimensional echocardiography (TDE), then the findings were analyzed.

RESULTSMSCT showed CAL in 12 of 34 patients involving 16 coronary arteries, including 9 (26%) dilated left coronary arteries (LCA), 1 constricted, 1 calcified and 1 LCA which had both stenosis and 4 (12%) dilated right coronary artery. TDE showed that 10 patients had 13 dilated coronary arteries, including 7 (21%) left coronary arteries and 6 (18%) right coronary arteries. TDE failed to show the abnormalities in 3 patients with coronary artery stenosis or calcification and in 2 patients with left descending artery dilation demonstrated by MSCT. However, no significant difference was found between the two methods (P > 0.05) in the rates of positive findings. The correlation between TDE and MSCT, in left as well as right coronary artery, was significantly positive (r = 0.90, r = 0.82, respectively, P < 0.01). However, compared with TDE, MSCT was significantly better in finding coronary artery stenosis and calcification (chi(2) = 24.3, P < 0.01).

CONCLUSIONSUse of MSCT may help better find the lesions of coronary artery, especially those in middle and distant sections as compared to TDE. MSCT is better than TDE in exploring coronary wall calcification and coronary artery stenosis. MSCT could be a helpful new addition to the current CAL monitoring method in long-term follow-up of patients with Kawasaki disease.
