Objective To investigate the effects of RNA interference (RNAi) targeting angiotensinconverting enzyme (ACE) on blood glucose,insulin resistance,as well as oxidative stress in type 2 diabetic rats.Methods Type 2 diabetic rats were divided into diabetes control group (caudal intravenation with control adenovirus named Ad5),gene treatment group (caudal intravenation with recombinant adenoviral vectors named Ad5-ACE-shRNA,expressing ACE gene-specific shRNA),and enalapril group (intragastric administration with enalapril every day).At the same time,the normal blood glucose control group was set up.All rats were injected two times during the experiment period.Blood glucose was measured before and after the intervention.At the third day of the experiment,expressions of ACE mRNA and protein in pancreas were evaluated by RT-PCR and Western blot,and serum concentrations of ACE and Ang Ⅱ were measured by ELISA.By the end of the experiment,insulin sensitivity index was calculated and expressions of glucose transporter 4 (GLUT4) protein of epididymal adipose tissue and NAD (P) H (p22phox) protein of pancreas were measured.Results Blood glucose levels in the gene treatment group [(17.8 ±1.1) mmol/L] and the enalapril group [(17.9 ± 1.2) mmol/L] were lower than that in the diabetes control group [(24.9 ± 1.3) mmol/L] when the experiment was finished.ACE mRNA and protein expressions in pancreas of the gene treatment group were significantly decreased compared with the diabetes control group (P ＜ 0.05).Serum concentrations of ACE and Ang Ⅱ in the gene treatment group were (16.37 ± 3.01) ng/ml and (18.24 ± 3.69)pg/ml,significantly lower than those of the diabetes control group [(46.67 ± 3.92) ng/ml and (44.93 ± 4.12) pg/ml respectively,both P＜0.05].Insulin sensitivity indexes of the gene treatment group and the enalapril group were (-5.14 ± 0.41) and (-5.17 ± 0.38),being all significantly higher than that of the diabetes control group (-6.18 ±0.46,both P＜0.05).Expressions of GLUT4 protein in epididymal adipose tissue were higher and expressions of p22phox protein in pancreas were lower in the gene treatment group and the enalapril group than those of the diabetes control group (both P＜0.05).Conclusions RNAi targeting ACE gene may delay the progress of hyperglycaemia and improve the situation of insulin resistance and oxidative stress.The RNAi technology may be used as a new strategy of gene therapy for diabetes mellitus.

Abstract: Objective　To construct a mouse model of Schistosoma japonicum liver disease induced by direct injection of Schistosoma japonicum eggs through the portal vein and evaluate its effectiveness, in order to provide a new animal model for schistosomiasis liver disease research. Methods　Fifteen 8-week-old C57BL/6 male mice were randomly divided into control group and egg injection group, with 5 in the control group and 10 in the egg injection group. On day -14, 5 000 live eggs were injected into the abdominal cavity of mice, and on day 0, the mice were anesthetized and the abdominal cavity was opened. 5 000 live eggs were injected through the portal vein, and the control group was injected with equal volume of phosphate buffer (PBS). 5 mice in the egg group were killed on day 10 and 30, respectively. The control group mice were killed on day 10, and their serum and liver tissue were collected. Hematoxylin eosin staining (HE) and Masson staining were performed, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), and liver hydroxyproline (HYP) content were detected using a microplate spectrophotometer. Liver fibrosis-related genes, Th1 and Th2 type immune response-related genes were analyzed by real-time fluorescence quantitative PCR (qPCR). Liver injury, egg granuloma and fibrosis, and adaptive immune response were detected to evaluate the effect of portal vein injection of eggs while inducing mouse model of schistosomiasis liver disease. Results　The results showed that significant egg granulomas appeared in the liver of mice after injection of eggs into the portal vein for 10 and 30 days. There was no statistically significant difference in the area of egg granulomas between the 10-day group and the 30-day group (t=0.975, P=0.332). Masson staining and liver hydroxyproline content detection showed significant fibrosis in the liver. The qPCR results showed that, compared with the control group, the expression levels of fibrosis marker genes, such as α⁃Sma (alpha smooth muscle actin), Col1a1 (collagen type Ⅰ alpha 1), and Tgfb1 (transforming growth factor beta 1), were significantly increased (t=6.380, 7.533, 5.314; P=0.002, 0.001, 0.007), and then decreased on the 30th day, with no statistical difference compared to the control group (t=0.940, 1.529, 1.746; P=0.778, 0.543, 0.457). At the same time, the expression levels of Th1 type immune response-related genes, such as tumor necrosis factor alpha (Tnf), interferon gamma (Ifng), and Th2 type immune response-related genes, such as interleukin-5 (Il5), interleukin-13 (Il13), significantly increased 10 days after eggs injection (t=6.163, 4.589, 5.651, 5.367; P=0.003, 0.018, 0.020, 0.009). In addition, there was no significant change in the levels of AST and ALT in the serum of each group of mice (t=0.982, 3.450; P=0.771, 0.074. t=1.164, 0.564; P=0.697, 0.917). Conclusions　A mouse model of schistosomiasis liver disease induced by portal vein injection of worm eggs was constructed. The study provides a new modeling method for studying the mechanism of liver fibrosis in schistosomiasis..

Herpetin (HPT) is an active monomer constituent isolated from lignanoid in seeds of Herpetospermum caudigerum. HPT shows inhibitory effects in hepatic injury and HBV-DNA and the replication. In the study, we successfully prepare herpetin liposomes by film dispersion method for the first time. The prescription process was optimized, with the entrapment efficiency as the index. According to the optimized prescription, the mass ratio of HPT: phospholipids: cholesterol was 2.44:78.05: 19.51, the hydration and de-molding process was performed with 0.5% F68 solution at 50 degrees C, and the water-bath ultrasonic time was 20 min. The HPT liposomes prepared by this method showed an average entrapment efficiency of (94.50 +/- 2.15)% and a particle size of (119.2 +/- 10.7) nm, which was consistent with the trial expectations and will lay a solid foundation for the hepatic targeting delivery system in future.

While the control was negative. Conclusion The targeted liposome contrast agent with highly specific biological activity was prepared successfully. The contrast agent could bind to human prostatic carcinoma cells specially and effectively in vitro.

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.
