[A case of poisoning by oral lime sulfur].

Lime sulfur is a common bactericide with strong alkalinity, and is highly corrosive to humans and animals. It is rare for lime sulfur poisoning clinically. This article discusses the clinical manifestations of a patient who was poisoned by oral lime sulfur. After the poisoning, the mucosa of the lips and pharynx broke, fever, and pulmonary inflammation quickly appeared. The pulmonary CT showed slight interstitial changes in both lungs. Through high flow oxygen inhalation, fluid infusion, drainage, maintenance of water and electrolyte balance, protection of important organ functions, and other symptomatic support and treatment, as well as control of blood pressure, blood sugar, maintenance of circulatory function and other targeted measures, the patient's condition gradually improved.

Molecular cloning and characterization of CD63 in common carp infected with koi herpesvirus.

CD63 is a member of the four-transmembrane-domain protein superfamily and is the first characterized tetraspanin protein. In the present study, we cloned the common carp (Cyprinus Carpio) CD63 (ccCD63) sequence and found that the ccCD63 ORF contained 711 bp and encoded a protein of 236 amino acids. Homology analysis revealed that the complete ccCD63 sequence had 84.08% amino acid similarity to CD63 of Sinocyclocheilus anshuiensis. Subcellular localization analysis revealed that ccCD63 was localized in the cytoplasm. Quantitative real-time PCR (qRT-PCR) analysis indicated that ccCD63 was expressed in the gill, intestine, liver, spleen, brain and kidney, with higher expression in spleen and brain tissues than in the other examined tissues. After koi herpesvirus (KHV) infection, these tissues exhibited various expression levels of ccCD63. The expression level was the lowest in the liver and highest in the brain; the expression level in the brain was 8.7-fold higher than that in the liver. Furthermore, knockdown of ccCD63 promoted KHV infection. Moreover, ccCD63 was correlated with the regulation of RIG-I/MAVS/TRAF3/TBK1/IRF3 and may be involved in the antiviral response through the RIG-I viral recognition signalling pathway in a TRAF3/TBK1-dependent manner. Taken together, our results suggested that ccCD63 upregulated the interaction of KHV with the host immune system and suppressed the dissemination of KHV.

EDACO, a derivative of myricetin, inhibits the differentiation of Gaoyou duck embryonic osteoclasts in vitro.

1. This study determined the effects of (E)-3-(2-(4-(3-(2,4-dimethoxyphenyl)acryloyl)phenoxy)ethoxy)-5,7-dimethoxy-2-(3,4,5-trimethoxyphenyl)-4H-chromen-4-one (EDACO) on the differentiation of Gaoyou duck embryonic osteoclasts cultured in vitro. 2. Bone marrow mononuclear cells (BM-MNC) were collected from 23-d-old Gaoyou duck embryos and induced by macrophage colony-stimulating factor and receptor activator of nuclear factor κB ligand in the presence of EDACO at different concentrations (i.e. 10, 20, 40, 80 and 160 µM). Tartrate-resistant acid phosphatase (TRAP) staining and resorption ability determination were conducted. 3. Results suggested that EDACO suppressed the shaping of positive multinucleated cells and the number of TRAP-positive cells in the 20, 40, 80 and 160 µM EDACO groups was significantly decreased (P < 0.05 or P < 0.01). Besides, the absorption activity of differentiated duck embryonic osteoclasts was significantly inhibited (P < 0.05) in both 80 and 160 µM EDACO groups. 4. Overall, EDACO can inhibit the differentiation of BM-MNC into mature osteoclasts in duck embryos.1.

[Analysis on the data of antibiotic prescriptions comment in China, 2014-2015].

OBJECTIVE: To evaluate the rationality of antibiotic use in the outpatient and emergency departments in some class 3A hospitals in China through International Network for Rational Use of Drugs(INRUD). METHODS: The antibiotic prescriptions were collected from the outpatient and emergency departments in 78 class 3A hospitals of 25 provinces through INRUD during 2014-2015. The basic information of the antibiotic prescriptions and the prescriptions rationality were evaluated. RESULTS: A total of 447 894 prescriptions of antibiotics were analyzed. From 2014 to 2015, the qualified rate the prescriptions increased from 91.52% to 93.08%, and the antibiotic use rate was similar(11.72% and 12.04%). The major irrational prescription type was inappropriate prescription, including inappropriate indication(32.42%, 34.02%)and inappropriate usage and dosage(24.22%, 18.56%). CONCLUSIONS: Totally, the antibiotic use in the outpatient and emergency department reached the standard in China. However, the use of antibiotics didn't meet the national requirements in some area. It is necessary to promote the rational use of antibiotics.
