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 observe the efficacy of cytokine-induced killer (CIK) cells on patients with advanced lung cancer. Methods:A total of 90 patients with advanced lung cancer were identified from January 2011 to December 2013. CIK therapy was given to 41 pa-tients in the observation group, whereas the other 49 patients in the control group received the best support treatments without che-motherapy or radiotherapy within one month of inclusion. Following up was conducted for the patients in the two groups, and KPS scores, median survival, and adverse reactions compared. Results:The KPS score in the observation group was higher than that of the control group after treatment (P=0.034). The median survival period of the observation group was eight months, which was one month longer than that of the control group (P=0.044). Major adverse reactions included fever, joint pain, and insomnia, which were recorded 51.22%, 36.58%, and 29.27%of occurrence, respectively. Conclusion:CIK cell therapy improved the quality of life and pro-longed the survival of advanced lung cancer patients with tolerable adverse reactions.

Serum p-amyloid peptide(Aβ)40 and Ap42 levels in patients with type 2 diabetes mellitus (T2DM)and atherosclerosis(AS)were detected by ELISA.The results showed that serum Ap40 level in T2DM group was significantly higher than that in the control group[(274.70±159.51 vs 162.63±87.58)pg/ml,P<0.05],especially in the diabetic patients accompanied with AS[(616.95±195.13)pg/m],P<0.01].Serum Ap40 level in simple AS group was also higher than that in control group[(318.52± 188.65)pg/ml,P<0.05].These results suggest that Ap40 is a risk factor of T2DM complicated with AS.However,there was no difference in serum Ap42 levels among various groups.

This study was designed to explone whether catalpol exerts a protective effects on kidney of diabetic rats and its possible mechanism.Insulin-like growth factor- I ( IGF- I ) and protein kinase B (PKB/Akt)mRNA and protein expression in kidney of diabetic rats were up-regulated as results of assessments by RT-PCR,immunohistochemistry and Western blot.Catalpol could partially reduce IGF- Ⅰ and Akt expressions in kidney of diabetic rats,and thus alleviate the damage of kidney.

Objective To evaluate the clinical application values of 64-row MSCT for apical hypertrophic cardiomyopathy(AHCM).Methods Twenty-one patients with AHCM were included in this study,14 patients were diagnosed by echocardiography(UCG),and 7 patients were diagnosed by MRL AU patients underwent MSCT exam,and 5 patients also had ventriculography and coronary angiography.The left ventricular wall thickness in end-systole and end-diastole phases were measured at MSCT workstation,the left ventricular apex thickening rate(LVAT)and the ratio of maximum wall thickness of the left ventrieular apex(LVA)to the left ventricular posterior wall thickness(LVA/LVPW)in end-diastole phase were calcdated.The left ventricular end-diastolie volume(LVEDV)and left venueular ejection fraction (LVEF)were quantitively evaluated with cardiac functional analysis software.The results were compared with the measurement results from the normal control group(30 volunteers).The independent-samples t test was used for the statistics.At the same time.the coronary stenosis was measured.Results Diffuse or partial thickening of the LV apical myocardium were found in the four-chamber view and two-chamber view of MSCT images.which leaded to the deformation of the left ventricle chamber.The LVEDV were(82.6±11.4)and(108.5±10.6)ml in the AHCM group and the control group,respectively;the LVA were (20.6±3.4)and(9.9±1.5)mm;LVA/LVPW were 2.1±0.5 and 1.1±0.2;the LVAT were(25.6±4.7)%and(81.5±8.5)%.There were significant differences in LVEDV,LVA,LVA/LVPW and LVAT between the two groups(t=8.32 and 15.29,P＜0.05;t=9.91 and 27.30,P＜0.05;respectively),but there were no statistical differences in LVPW and LVEF between the two groups(t=0.26 and 1.13.P＞0.05).Five patients had myocardium bridging and 4 patients had coronary stenosis.Conclusion AHCM can be diagnosed accurately with MSCT,and the cardiac anatomy.function and coronary artery are also assessed simultaneously.

Palmatine, the main effective ingredient of Fibraurea recisa, is a typical berberine isoquinoline alkaloid with extensive anti-inflammatory and antibacterial activities. In this work, the studies of metabolomics and transcriptomics were utilized to detect differentially expressed genes (DEGs) that are significantly associated with the synthesis of palmatine. In addition, eight of these DEGs were verified by quantitative real-time PCR (qRT-PCR). A total of 106 alkaloids were detected in the metabolomics study, including 23 isoquinoline alkaloids. Palmatine ranked in the top ten of differential metabolites in the group of root vs leaf, and its relative content in root was about 47.5 times higher than that in leaf. In the transcriptomics study, a total of 188 genes were annotated to the pathway of isoquinoline alkaloid biosynthesis. Among them, there were 36 DEGs were significantly different. In the comparison group of root and leaf, a total of 33 DEGs were significantly different, and 30 DEGs were annotated on the biosynthetic pathway of palmatine. Finally, the results of the correlation analysis between metabolomics and transcriptomics showed that the expression patterns of four gene sequences were screened to be significantly correlated with palmatine. The results of qRT-PCR experiments showed that the expression trends of eight DEGs were consistent with the results of transcriptomic. This study not only enriched the omics data of F. recisa, but also established the foundation for the study of the synthetic biology of palmatine. It further provided a reference for the analysis of the key enzyme genes on the biosynthetic pathway of other isoquinoline alkaloids.
