A simple,reliable RPHPLC method on ODS column with UV detector for deter-mination of the anticoagulant rodenticide coumatetralyl in animal tissue was developed.1,1′-Bi-(2-Naphthol)was used as an internal standard to check the process ofexperiments.The mean recoveries from the spiked rabbit liver were around 90% atthe levels of 0.4-16mg/kg.The coeffecint of variation of 5 determination was 3.2%.The results showed that this method has a satisfactory reproducibility.The methodis practical for examining poisons in poisoning cases.

Nine Rabbits were orally administrated with a single dose of 25mg/kg,100mg/kgcoumatetralyl to establish poisoning model.Poisoning sympton and pathological changes were observed.Coumatetralyl content in main internal organsand muscle was determined by RPHPLC method.The results were discussed.

The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.

OBJECTIVE: To elucidate the correlation between CKLF-like marvel transmembrane domain containing member (CMTM5) gene and the risk of in-stent restenosis (ISR) with coronary artery disease (CAD) patients and to detect the effects and mechanisms of CMTM5-stimulated genes on human vascular endothelial cells (ECs) proliferation and migration. METHODS: A total of 124 hospitalized patients in Shijitan Hospital were enrolled in this study. All the CAD patients were detected with platelet reactivity and grouped into two groups according to platelet reactivity; ISR was conformed by coronary angiography; RT-PCR method was used to detect CMTM5 gene expression; The CMTM5 over expression, reduction and control EC lines were established; Cell count, MTT, Brdu and flow cytometry methods were used to detect the proliferation of ECs, scratch and transwell experiments to test the migration of ECs, Western blot was used to detect signal path expressions. RESULTS: CMTM5 gene expression in HAPR (High on aspirin platelet reactivity) group was 1.72 times compared with No-HAPR group, which was significantly higher than No-HAPR group. HAPR group ISR rate was 25.8% (8 cases), the incidence of No-HAPR ISR group was 9.7% (9 cases), and the results showed that in HAPR group, the incidence of ISR was significantly higher than that in No-HAPR group (P=0.04, OR=0.04, 95%CI=1.16－7.52), which showed that CMTM5 gene was significantly correlated with the risk of ISR. In HAPR group ISR rate was 25.8% (8 cases), the incidence of ISR in No-HAPR group was 9.7% (9 cases), and the results showed that the risk of ISR in HAPR group was significantly higher than that in No-HAPR group. All the results showed that CMTM5 was significantly correlated with the risk of ISR in CAD patients (P < 0.05). CMTM5 overexpression inhibited the proliferation and migration ability of ECs (P < 0.05), PI3K/Akt signaling pathways were involved in the role of regulation on ECs. CONCLUSION Our results revealed that CMTM5 gene was closely related with ISR, CMTM5 overexpression may repress ECs proliferation and migration through regulating PI3K-Akt signaling.

OBJECTIVE: To elucidate the correlation between CKLF-like MARVEL transmembrane domain containing member 5 (CMTM5) gene and the risk of coronary artery disease (CAD), and to detect the effects of CMTM5 gene expression changes on the ability of adhesion and migration of THP-1 cells. METHODS: Using case-control method, a total of 700 hospitalized patients in Shijitan Hospital were enrolled in this study. CAD were diagnosed by coronary angiography, which was defined as at least one blood vessel diameter stenosis ≥50% according to the result of coronary angiography. Reverse transcription-polymerase chain reaction (RT-PCR) method was used to detect CMTM5 gene expression; enzyme linked immunosorbent assay (ELISA) method to detect the plasma level of CMTM5; and Logistic regression to analyze CMTM5 genes and the risk of CAD. Human vascular endothelial cells (ECs) and THP-1 cells were cultivated, adhesion and Transwells experiments were used to evaluate the chemotactic capabi-lity of CMTM5 gene on THP-1 cells. RESULTS: In this study, 350 CAD patients matched with 350 control patients were included. RT-PCR results revealed CMTM5 mRNA expression in CAD group was 3.45 times compared with control group, which was significantly higher than that in control group (P < 0.05). The levels of CMTM5 plasma protein in CAD group was (206.1±26.9) μg/L, which was significantly higher than that in control group (125.3±15.2) μg/L (P < 0.05). After adjusted for the risk factors of age, gender, BMI, smoking, hypertension, diabetes and hyperlipidemia, Logistic regression analysis results indicated that CMTM5 was the susceptibility factors of CAD, which still had significant correlation with CAD (P < 0.05). Adhesion and Transwells experiments results revealed that the numbers of adhesion and migration of THP-1 cells in CMTM5 overexpression ECs group (EO group) were significantly higher than that in lenti-mock infected ECs group (EO-MOCK group), non-infected ECs group (EN group), lenti-mock infected ECs group (ES-MOCK group), and CMTM5 suppression ECs group (ES group). On the contrary, the numbers of adhesion and migration of THP-1 cells in ES group were significantly lower than that in the other four groups (P < 0.01). CONCLUSION CMTM5 gene was closely related to the development of CAD. CMTM5 overexpression promoted the adhesion and migration of THP-1, which might play a part in the mechanisms of atherosclerosis and CAD.
