In order to observe the effect of the immune and weight of chickens after use the attenuated vaccine with low dose of chicken infectious anemia virus (CIAV). In this study, the effects of low dose of CIAV on the weight of SPF chickens and NDV antibody production were observed by simulated experiments. The results showed that 10 EID50 and 5 EID50 CIAV per plume attenuated NDV vaccines were used to cause the weight loss of SPF chickens. Compared with the use of the non contaminated vaccine group, it has significant difference. And NDV antibody levels compared with the use of the non contaminated groups also decreased after use the vaccine with two doses of CIAV contaminated. It has significant difference. A certain proportion of CIAV antibody positive was detected at the beginning of the second week after use the NDV vaccine with two doses of CIAV contaminated. The detection of a high proportion of CIAV nucleic acid was detected in the first week after the use of a contaminated vaccine. The results of the study demonstrate the effects of CIAV pollution on the production and immune function of SPF chickens, and it is suggested that increasing the detection of viral nucleic acid can help save time and improve the detection rate in the detection of exogenous virus contamination by SPF chicken test method.

Network pharmacology, as a new developmental direction of drug discovery, was generating attention of more and more researchers. The key problem in drug discovery was how to identify the new interactions between drugs and target proteins. Prediction of new interaction was made to find potential targets based on the predicting model constructed by the known drug-protein interactions. According to the deficiencies of existing predicting algorithm based bipartite graph, a supervised learning integration method of bipartite graph was proposed in this paper. Firstly, the bipartite graph network was constructed based on the known interactions between drugs and target proteins. Secondly, the evaluation model for association between drugs and target proteins was created. Thirdly, the model was used to predict the new interactions between drugs and target proteins and confirm the new predicted targets. On the testing dataset, our method performed much better than three other predicting methods. The proposed method integrated chemical space, therapeutic space and genomic space, constructed the interaction network of drugs and target proteins, created the evaluation model and predicted the new interactions with good performance.

OBJECTIVE: To explore the molecular basis for two brothers affected with globozoospermia. METHODS: Whole exome sequencing was carried out for both patients. Candidate variant was verified by Sanger sequencing and quantitative real-time PCR (qRT-PCR). RESULTS: Whole exome sequencing, Sanger sequencing and qRT-PCR verification revealed a heterozygous c.384dup (p.Glu129*) variant in the DPY19L2 gene in the two brothers and their mother. A large heterozygous deletion, spanning approximately 164.5 kb and encompassing the entire DPY19L2 gene, was detected on chromosome 12 of the two patients and their father. CONCLUSION The c.384dup (p.Glu129*) variant and deletion of the DPY19L2 gene probably underlie the pathogenesis of globozoospermia in the two patients, which was in keeping with the autosomal recessive inheritance of disease in this pedigree.

Objective To investigate the relationship between serum markers β amyloid (Aβ), tau and thyroid hormone levels and post-stroke cognitive impairment (PSCI) in the acute phase of cerebral infarction. Methods A total of 214 patients with acute cerebral infarction were enrolled. The baseline data and serological indicators were collected and the cognitive function of patients was evaluated. All patients were divided into cognitive impairment group and normal group based on follow-up results. The differences of Aβ1-42, tau protein and thyroxine levels between the two groups and their relationship with disease progression were analyzed. The Cox regression analysis and ROC curve were used to compare the above parameters to predict the development of PSCI. Results The total protein level of Tau (210.6 ±98.9 pg/mL) was higher and Aβ1-42 (426.1 ±123.5 pg/mL) and triiodothyronine (T3) (1.43 ±0.57 nmol/L), free thyroxine (FT4) (13.15±2.23 pmol/L) was significantly lower in the cognitive impairment group than in the normal group (P<0.05). Tau protein (r=-0.457), Aβ1-42 (r=0.348), T3 (r=0.211), and FT4 (r=0.306) were all associated with disease progression (P<0.05). Cox regression analysis showed that Aβ1-42 and T3 were important influencing factors in the occurrence of PSCI. The area under the curve of Aβ1-42 combined with T3 was 0.841. The specificity and the sensitivity were 74.8% and 85.3%, respectively, with a diagnostic cutoff value of 0.572. Conclusion Aβ1-42 and T3 levels in the acute phase of cerebral infarction may predict the progression of PSCI.

Objective To investigate the clinicopathological significance of PDC in liver metastases and analyze the correlation of PDC between liver metastases and primary lesions. Methods Retrospective analysis of 72 matched cases of colorectal cancer with liver metastases was performed. The PDC in primary tumor and liver metastatic lesion was interpreted synchronously, and then the relationship between PDC in liver metastasis and clinicopathological parameters was analyzed based on the correlation of PDC between primary and metastatic lesions. In addition, PDC were interpreted in accordance with Uenos' standard. Results Among the 72 cases of liver metastasis of colorectal cancer, the number of G1, G2, and G3 graded by PDC was 28, 24, and 20, respectively. The PDC in liver metastatic lesion was correlated with tumor budding in liver metastatic lesion and PDC grade of primary lesion. No significant correlation with the size and number of liver metastatic lesion, the site, WHO grade, depth of invasion, lymph node metastasis, vascular invasion or tumor budding of the primary lesion was observed. Conclusion A positive correlation is found between liver metastasis of colorectal adenocarcinoma and PDC grade of primary tumor. Evaluating the PDC grade of primary tumor may provide a reference for the risk of liver metastasis.

Objective:To explore the effects of gaseous formaldehyde exposure on male Sprague-Dawley rat brain function and synaptic protein expression, as well as the neuroprotective effects of resveratrol.Methods:Eighty-four male Sprague-Dawley rats were randomly divided into seven group with 12 in each group: control group (N), gaseous formaldehyde accumulation low concentration group (FL group), gaseous formaldehyde accumulation medium concentration group (FM group), gaseous formaldehyde accumulation high concentration group (FH group), gaseous formaldehyde accumulation low concentration + resveratrol group (FLR group), gaseous formaldehyde accumulation concentration + resveratrol group (FMR group) and gaseous formaldehyde accumulation high concentration + resveratrol group (FHR group). The animal model of gaseous formaldehyde accumulation was established by gas formaldehyde exposure method.Learning and memory function was tested by Morris water maze. Cortical and hippocampal neurogranin (Ng) protein expression in brain cortex and hippocampus was measured by Western blot.Results:(1) Compared with the escape latency and original platform retention time of rats in group N ((19.75±4.08) s, (43.47±2.43) s), the escape latency of rats in FM and FH groups was prolonged ((25.52±2.98) s, (27.45±2.39) s, t=-4.97, -5.82; both P<0.01), the retention time of the original platform was shortened ((30.99±4.21) s, (18.70±2.58) s, t=10.24, 25.71; both P<0.01). Compared with the corresponding formaldehyde accumulation groups such as the FM and FH groups, the escape latency of the rats in the FMR and FHR groups was significantly longer ((21.37±3.80) s, (24.26±3.56) s, t=1.86, 3.93; both P<0.05), the retention time of the original platform was significantly prolonged ((40.33±3.63)s, (23.46±4.73)s, t=-7.50, -3.95; both P<0.01). (2) Compared with the expression of Ng in cortex and hippocampus of rats in group N ((0.99±0.03), (1.07±0.03)), the expression of Ng protein in cortex and hippocampus of rats in FM and FH groups was significantly reduced((0.62±0.06), (0.39±0.03), (0.77±0.09), (0.46±0.10), t=11.55, 14.08, 11.51, 13.17; all P<0.01). Compared with the corresponding formaldehyde accumulation groups such as the FM and FH groups, the expressions of Ng in the cortex and hippocampus of the rats in the FMR and FHR groups were significantly increased ((0.94±0.11), (0.48±0.04), (0.95±0.05), (0.60±0.09), t=-5.26, -2.09, -5.32, -2.21; all P<0.05). Conclusion:Resveratrol can improve the learning and memory function of rats caused by the accumulation of gaseous formaldehyde.The mechanism may be related with the upregulation of Ng.
