Anti-tumor effects of Solanum nigrum L. extraction on C6 high-grade glioma.

Ethnopharmacological Relevance: Solanum nigrum L. (SN) is a traditional Chinese medicine with anti-tumor effects, has been used in cancer for centuries, but the role on high-grade gliomas (HGG) is not clear.

Aim Of The Study: This work was to investigate the anti-tumor effects of SN extract on rat C6 glioma in vitro and in vivo, providing a new medium for the treatment of HGG.

Wetting Behavior and Tribological Properties of Polymer Brushes on Laser-Textured Surface.

Polymer brush layers can act as effective lubricants owing to their low friction and good controllability. However, their application to the field of tribology is limited by their poor wear resistance. This study proposes a strategy combining grafting and surface texturing to extend the service life of polymer brushes.

[Analyais of infection and related factors among special population in Changzhou City, Jiangsu Province].

[Investigation on soil - transmitted nematode infections in national surveillance sites in Jiangsu Province from 2006 to 2015].

Objective: To understand the status of soil-transmitted nematode infections in rural residents so as to provide the evidence for formulating the guidance for prevention and control of the diseases.

Methods: The national surveillance sites of soil-transmitted nematode infections were established in Shuyang County, Suqian City, Jiangsu Province from 2006 to 2015. At least 1 000 fecal samples of residents aged 3 years or above were collected in every autumn, and the intestinal helminth eggs were detected with the Kato-Katz technique and the eggs were detected by the cellophane tape method for children aged 3-12 years.

[Epidemiological investigation of second intermediate hosts of Clonorchis sinensis in Pizhou and Xinyi cities of Jiangsu Province].

Objective: To understand the endemic situation of Clonorchis sinensis in its second intermediate hosts in Pizhou and Xinyi cities of Jiangsu Province, so as to provide the evidence for the further control and treatment.

Methods: Pseudorasbora parva and Abbottina rivularis were caught from the natural water body of Pizhou and Xinyi cities, and the tabletting microscopy method was applied to test the metacercaria of C. sinensis.

[Effects of training of human intestinal parasitic diseases for basic health staff in Jiangsu Province].

Objective: To evaluate the effect of the training of human intestinal parasitic diseases for basic health staff.

Methods: A workshop including theory courses and practical operations was carried out. At the end of the workshop, the effects were evaluated through the examinations of theory and film-reading.

[Prediction of hookworm incidence with time-series model in Jiangsu Province].

Objective: To explore the feasibility of autoregressive integrated moving average (ARIMA) to predict the infection rates of hookworm in Jiangsu Province.

Methods: From 1990 to 2006, the infection rates of hookworm were used for a training data set. As to obtain a stationary data set, the training data set was second-order differenced using the version SAS 9.

[Comparison between two expression ways on cysteine protease of Clonorchis sinensis].

Objective: To compare the prokaryotic expression system and eukaryotic expression system for the expression of cysteine protease of Clonorchis sinensis, and the diagnostic efficiency of their objective products.

Methods: According to the sequence of cysteine protease of C. sinensis, two pairs of primers were designed to amplify the genes from the total cDNA of C.

[Cloning, expression and evaluation on effect in serological diagnosis of cysteine protease of Clonorchis sinensis].

Objective: To clone and express the cysteine protease of Clonorchis sinensis and evaluate its effect on immunodiagnosis of human clonorchiasis.

Methods: Based on a cysteine protease gene fragment of C. sinensis (CS-CP, GenBank accession: AF093242), a pair of primers were designed and amplified from total cDNA of C.

[Performance evaluation of rural latrine renovation in key schistosomiasis control areas, Jiangsu Province].

Objective: To evaluate the hygienic, environmental, social and economic benefits achieved by rural latrine renovation in key schistosomiasis control areas, Jiangsu Province.

Methods: Eights villages (evaluation villages) that finished and the three villages (control villages) that did not finish the latrine renovation work were sampled and investigated through field visits, questionnaire, referring to information and so on, to collect relevant data, and human waste samples were detected for laboratory indicators in hygiene and environment, in key schistosomiasis control areas in three counties (cities, districts), Jiangsu Province.

Results: A total of 11 villages and 220 households were investigated.

[Process for lymphatic filariasis elimination in Jiangsu Province, China].

Objective: To review the process of lymphatic filariasis elimination in Jiangsu Province, and summarize the control experience.

Methods: The data of epidemic status, control and surveillance of lymphatic filariasis were collected and analyzed in Jiangsu Province from 1950s to 1990s.

Results: Lymphatic filariasis was endemic in 71 counties (cities) among all 75 counties (cities) in Jiangsu Province.

[Epidemic situation and control of soil-transmitted nematodiasis in Jiangsu Province].

Objective: To analyze the prevalence changes and the control measures of soil-transmitted nematodiases in Jiangsu Province in the recent 20 years and evaluate the control effect, so as to explore the control strategies and measures appropriate to current epidemic characteristics.

Methods: The data on surveillance, control measures and control effect of soil-transmitted nematodiases in Jiangsu Province from 1990 to 2009 were collected and analyzed.

Results: Different control programs were taken in different control stages in Jiangsu Province.
