Objective:To investigate the expression level of poly ADP ribose polymerase 14(PARP14) in thyroid cancer and its relationship with the clinicopathologic characteristics of the patient with thyroid cancer and evaluate the role of PARP14 in the progression of thyroid cancer.Methods:The gene expression interaction analysis (GEPIA) database was used to analyze the expression of PARP14 in normal thyroid tissue and thyroid cancer tissue and its relationship with disease-free survival of patients. The expression of PARP14 in thyroid cancer tissue and adjacent tissues of the patient with thyroid cancer was evaluated by immunohistochemistry. According to the staining intensity, the patients were divided into the high expression group and the low expression group, and the correlation between the expression of PARP14 and clinical pathological characteristics was analyzed. The effect of PARP14 on the proliferation of thyroid cancer cells was investigated by clone formation testing and MTT testing.Results:The results of bioinformatics analysis and immunohistochemistry showed that PARP14 was overexpressed in thyroid cancer tissue, and the disease-free survival rate of the patient with high expression was lower. The expression level of PARP14 was correlated with tumor stage and intrathyroidal spread (all P<0.05). The results of the clonogenic assay and the MTT assay showed that the expression of KIF4A could promote the proliferation of thyroid cancer cells ( P<0.05). Conclusions:PARP14 is highly expressed in thyroid cancer and is related to the clinicopathological characteristics of patients, suggesting that it may be a therapeutic target for thyroid cancer.

OBJECTIVE: To establish a clinically applicable model of rapid identification of adverse drug reaction program (RiADP) for risk management and decision-making of clinical drug use. METHODS: Based on the theory of disproportion analysis, frequency method and Bayes method, a clinically applicable RiADP model in R language background was established, and the parameters of the model were interpreted by MedDRA coding. Based on the actual monitoring data of FDA, the model was validated by the assessing hepatotoxicity of lopinavir/ritonavir (LPV/r). RESULTS: The established RiADP model included four parameters: standard value of adverse drug reaction signal information, empirical Bayesian geometric mean value, ratio of reporting ratio and number of adverse drug reaction cases. Through the application of R language parameter package "phViD", the model parameters could be output quickly. After being encoded by MedDRA, it was converted into clinical terms to form a clinical interpretation report of adverse drug reactions. In addition, the evaluation results of LPV/r hepatotoxicity by the model were matched with the results reported in latest literature, which also proved the reliability of the model results. CONCLUSIONS In this study, a rapid identification method of adverse reactions based on post marketing drug monitoring data was established in R language environment, which is capable of sending rapid warning of adverse reactions of target drugs in public health emergencies, and providing intuitive evidence for risk management and decision-making of clinical drugs.

Fibroblast growth factor 21 (FGF21) has been only reported to prevent type 1 diabetic nephropathy (DN) in the streptozotocin-induced type 1 diabetes mellitus (T1DM) mouse model. However, the FVB (Cg)-Tg (Cryaa-Tag, Ins2-CALM1) 26OVE/PneJ (OVE26) transgenic mouse is a widely recommended mouse model to recapture the most important features of T1DM nephropathy that often occurs in diabetic patients. In addition, most previous studies focused on exploring the preventive effect of FGF21 on the development of DN. However, in clinic, development of therapeutic strategy has much more realistic value compared with preventive strategy since the onset time of DN is difficult to be accurately predicted. Therefore, in the present study OVE26 mice were used to investigate the potential therapeutic effects of FGF21 on DN.

Objective To evaluate the application value of quantitative immune fecal occult blood test (FOBT) in colonoscopy for the screening of colorectal cancer in health check-up participants. Methods The subjects were selected from July 2017 to June 2018 in the Health Management Center of the Second Affiliated Hospital of Suzhou University. The subjects were the healthy individuals who chose quantitative immune FOBT or chemical method plus immunogold double-method FOBT (referred to as"double-method FOBT"), excluding those who had interfering factors. Individuals with a positive result in primary screening were selected and conducted with colorectal cancer by colonoscopy. If the polyploidy lesions were observed during colonoscopy, the biopsy or excision was performed, and the pathological diagnosis was performed. The positive rate of primary screening, compliance rate of colonoscopy and pathological results of colonoscopy were compared between the two methods. Quantitative immunoassay FOBT was analyzed in different gender, age group, physical examination nature, positive rate of primary screening, compliance rate of colonoscopy and pathological results of colonoscopy. Results 18 728 people chose quantitative immunoassay FOBT and 6 212 people chose double-method FOBT at the same time. There was no significant difference in gender and age between the two groups (all P>0.05), which was comparable. The detection rate of quantitative immune FOBT was higher than double-method FOBT (74.62% vs 32.23%, P<0.001). The positive rate of quantitative immune FOBT in primary screening was lower than double-method FOBT (4.11% vs 5.34%, P=0.003). The colonoscopy screening rate in positive population by quantitative immune FOBT was higher than double-method FOBT (27.83% vs 13.08%, P=0.001). These differences were statistically significant. The detection rate of total lesions by colonoscopy was 71.88% in positive population by quantitative immune FOBT. It was 42.86% in double-method FOBT. There was no statistical difference between the two methods (P=0.05). The detection rates of quantitative immune FOBT were significantly different among different genders, ages and physical properties (all P<0.001). The detection rate was higher in males than in females (79.14% vs 68.75%). The detection rate was highest in the group between 40 and 59 years old (79.96%). The individual detection rate was higher than the group (90.08% vs 66.07%). The positive rates in primary screening were significantly different among different ages (P=0.001).It was highest in the group aged 60 or above (5.59%). The colonoscopy screening rate in positive population by quantitative immune FOBT was highest in the group aged 50 or above (36.96%). The detection rate of inflammatory lesions were significantly different among different ages (P<0.001). The detection rate of colorectal cancer in males was higher than in females (11.11% vs 0.00%, P=0.009). In addition, with the increasing of fecal occult blood value, the detection rate of cancer was increased (P=0.041). Conclusion The quantitative immune FOBT is an ideal non-invasive examination for early screening of colorectal cancer. It has important application values.
