is an obligate intracellular parasite that invades nearly all nucleated cells of a broad spectrum of vertebrate hosts, and which may cause serious disease in immunocompromised patients, as well as in the immunologically incompetent fetus. This study aimed to establish a loop-mediated isothermal amplification (LAMP) technique to rapidly detect in the blood infection by targeting the 529 bp repeat element of . A turbidity monitoring system, together with visual reagent, was used to test the amplification result of the LAMP assay.

Freezing is a frequently used way to expand the storage life of foods with high water content. Under suitable cooling rates, frozen systems attain a condition of maximum freeze concentration, which is characterized by the glass transition temperature (T '), end point of freezing or onset of melting (T '), and concentration of solids (X ') in the maximum-freeze-concentrated matrix. The value of T ', T ', and X ' depends on the chemical composition of frozen system.

Objective: To investigate the Demodex infection status and influencing factors in medical students in Wuhu City.
Methods: The mite specimens were collected by the cellophane tape method, and the influencing factors were investigated through the questionnaires.
Results: A total of 316 medical students were surveyed, 117 students were infected with Demodex mite, and the total infection rate was 37.
This study aims to explore the influences of Paraoxonase-1 (PON1) involved in airway inflammation and remodeling in asthma. Mice were divided into control, asthma, asthma + PON1 and asthma + NC groups, and asthma models were established via aerosol inhalation of ovalbumin (OVA). HE, Masson, and PAS stains were used to observe airway inflammation and remodeling, Giemsa staining to assess inflammatory cells in bronchoalveolar lavage fluid (BALF), qRT-PCR and Western blot to detect PON1 expression, lipid peroxidation and glutathione assays to quantify malondialdehyde (MDA) activity and glutathione peroxidase (GSH) levels, ELISA to determine inflammatory cytokines and immunoglobulin, and colorimetry to detect PON1 activities.

Methods: The livestock and poultry (definitive hosts) were purchased from the farmers living in the water areas, including South Luohe, Yaohe, Jiaogang and Gaotang Lakes, and dissected the viscera of these collected hosts to obtain the parasitic samples. Then the specimens were microscopically identified, with reference to the descriptions in previous literatures for counting the zoonotic species found in these areas.

Fixed samples of Clonorchis sinensis and Fasciolopsis buski were stained with acetocarmine and malachite green, or stained with acetocarmine only. The samples displayed three different colors after staining with acetocarmine and malachite green. The digestive system, excretory system and the surrounding muscle tissue were stained reddish, the uterus was bright green, and the vitellarium at each side of the worm was tan.

Objective: To investigate the epidemic situation of Metorchis orientalis in Wuhu City, Anhui Province.
Methods: Three lakes (Fengming, Longwo and Kui lakes) were selected in Wuhu City, and the poultries around the lakes and freshwater fishes in the lakes were captured to test the infection of M. orientalis, and the infection rates were calculated.

Objective: To understand the zoonotic trematode species identified in domestic animals from Huainan area, Anhui Province, so as to supply the evidence for the prevention of zoonoses.
Methods: The livestock/definitive hosts were commercially available on category basis, and sacrificed for obtaining the parasitic samples via dissecting the viscera. The specimens were microscopically identified, with reference to the descriptions in the previous literature.
Objective: To investigate the species of Cheyletoid mites breeding status in the stored traditional Chinese medicinal materials and the relationship between its community and habitats.
Methods: A total of 60 samples of the traditional Chinese medicinal materials were collected from Huainan, Wuhu and Xuancheng in China. The mites were isolated with shakesieve shock, directicopy, Tullgren funnel, waternacopy and redricopy, and identified and counted under the light microscope.

Background: Chemokines have strong chemoattractant effects and are involved in a variety of immune and inflammatory reactions, such as attracting activated T lymphocytes, neutrophils, monocytes and natural killer cells via the pathway of G protein-coupled receptors to sites of inflammatory injury and contribute to wound repair. This investigation was designed to assess the levels of chemokine interferon-gamma inducible protein-10 (IP-10) and IP-10 mRNA, and the relationship between IP-10 mRNA and HBV-DNA and alanine aminotransferase (ALT) in patients with chronic hepatitis B.
Methods: The levels of IP-10 mRNA in peripheral blood mononuclear cells (PBMCs) were kinetically detected by real-time polymerase chain reaction (PCR).

The effects of reproductive hormone on mouse embryo sexes were studied with in vitro fertilization (IVF), in vitro culture (IVC) and sex identification. Results showed that it had no adverse effects on embryos cleavage and development after the embryos were incubated with the fertilization media with 17beta-E2, FSH and progesterone respectively at the concentration of this study. Mice embryos sex ratios significantly deviated from 1:1(P < 0.
