To understand the status of chronic filariasis patients in Jiangxi Province in 2018, so as to provide insights into the follow-up care of the patients.
In 2018, a case follow-up study was conducted in all registered patients with chronic filariasis in previously endemic areas of Jiangxi Province, and a clue investigation was done for identifying the missing patients. In addition, the data of caring sites for chronic filarisis patients were collected and analyzed in the province.
A total of 802 chronic filariasis patients were identified in 56 counties (districts) of Jiangxi Province in 2018. The patients had a male/female ratio of 1∶1, and 85.41% had ages of over 70 years. There were 58.60%, 93.89%, 17.21% and 3.62% of chronic filariasis patients with lymphangitis, lymphedema/elephantiasis, chyluria and hydrocele, respectively. A total of 273 caring sites were assigned in 56 counties (districts) of Jiangxi Province, and 306 caring activities were carried out in 2018.
The number of chronic filariasis patients has significantly decreased in Jiangxi Province; however, the care remains to be intensified for chronic filariasis patients.

To understand the distribution of
snails and changes of water levels in Gaoyou sections of the Li Canal following the operation of the eastern route project of the South-to-North Water Diversion Project.
The
snails were monitored in the river banks and water bodies of Gaoyou sections of the Li Canal by means of systematic sampling combined with environmental sampling as well as collection of the floaters from 2014 to 2019, and the water levels were collected in Gaoyou sections of the Li Canal at the typical hydrological year before the operation of the eastern route project of the South-to-North Water Diversion Project and during the period between 2016 and 2019.
A total area of 235.42 hm
were investigated and a total of 75.8 kg floaters were collected in Gaoyou sections of the Li Canal from 2014 to 2019; however, no snails were found. The water level in Gaoyou sections of the Li Canal was predominantly high in the flood season and low in the dry season before the operation of the eastern route project of the South-to-North Water Diversion Project, and the water level was elevated in the dry season and relatively low in the flood season after the operation of the project.
Following the operation of the eastern route project of the South-to-North Water Diversion Project, the original river bank that is characterized by "land in winter and water in summer" has changed in Gaoyou sections of the Li Canal, which is not favorable for snail breeding.

In order to follow this development trend, the human parasitology teaching team makes a reasonable use of modern information techniques, actively promotes the construction and application of online resources, and conducts mixed online and offline teaching based on MOOC resources and the experimental teaching digital platform. This mixed teaching model has shown a positive impact on both teaching and learning among teachers and students; however, students' personalized independent and deep learning remains unsatisfactory. It is suggested that the online course resources construction, teaching design and digital literacy remain to be increased, so as to create a high-level, innovative and challenging online-offline mixed "golden course".
To investigate the seroprevalence of
infections among neonates in Fujian Province, so as to provide insights into the development of interventions for the prevention and control of congenital toxoplasmosis.
A total of 1 045 neonates delivered in Fujian Province from 2017 to 2018 were recruited, including 387 preterm infants and 658 full-term infants. Umbilical cord blood was sampled from all neonates, and the seroprevalence of anti-
IgG antibody was detected and compared between preterm and full-term infants. BAY-1895344 In addition, elbow venous blood samples were collected from neonates'mothers, and the seroprevalence of anti-
IgG antibody was detected and compared between preterm and full-term infants'mothers.
The overall seroprevalence of anti-
IgG antibody was 9.38% among the 1 045 neonates in Fujian Province. The seroprevalence of anti-
IgG antibody was 18.35% in the 387 preterm infants, and there was no significant difference in the seroprevalence of anti-
IgG antibody between male and female inan in full-term infants and their mothers. Prenatal detection of T. gondii infections and health education pertaining to toxoplasmosis prevention and control knowledge are required to be strengthened to effectively reduce the incidence of congenital toxoplasmosis.
To analyze the sequences of mitochondrial cytochrome C oxidase subunit I gene (
) and 18S ribosomal RNA gene (
), so as to identify the feasible DNA barcodes for 4 species of cheyletid mites and improve the DNA barcoding database for cheyletid mites.
Cheyletid mite samples were collected from small-scale flour mills in Fuyang, Wuhu and Tongling cities of Anhui Province from May 2018 to July 2019, extracted and morphologically identified. Then, genomic DNA was extracted from a single cheyletid mite, and the
and
gene sequences were obtained by PCR amplification, cloning and sequencing. The obtained sequences were aligned using the BLAST software. Multiple sequence alignment was done using the software ClustalX version 1.83 using the known gene sequences from cheyletid mites. The genetic distance was calculated using the software MEGA X, and the phylogenetic tree was created using the maximum likelihood method.
The DNA barcoding results of
,
and
were consistent with the morphological identification, while no sequences pertaining to
were retrieved in the GenBank database.
