Reuse of waste oil in cooking has been the social concern for long time, but until now there is no reliable method to identify the gutter oil.In this work, based on the generation of long-chain aliphatic aldehydes in the refinement of gutter oil, gutter oil and adulterate cooking oil were identified by determining hexanal, heptanal, octanal, nonanal and decanal in oil sample with high perfomance liquid chromatography (HPLC) method using O-(3-(9H-carbazol-9-yl)propyl)hydroxylamine as the fluorescent derivative reagent.At first, 10 μL of oil sample was dissolved in 200 μL of isopropanol, then reacted with O-(3-(9H-carbazol-9-yl)propyl)hydroxylamine to form the stable derivatives, extracted with acetonitrile and injected into HPLC for analysis.The derivatives were separated on a C18 column within 15 min with ACN-H2O (90∶10, V/V) as mobile phase.The fluorescence detector was set at λex/λem=292 nm/348 nm.The linear range of 5 kinds of long-chain aliphatic aldehydes was 0.01-1.00 μmol/L with limit of detection (LOD, S/N=3) of 0.05-0.10 nmol/L, and the spiked recoveries were 95.6%-101.4%.The results showed that the edible oils obtained from supermarket almost had no hexanal, heptanal, octanal, nonanal, decanal, but these aldehydes increased significantly in gutter oil.Thus the 5 kinds of long-chain aldehydes could be used as the indictor of gutter oil.Taking the advantage of good specificity, higher sensitivity, good accuracy and simplicity, the method was suitable for the rapid identification of gutter oil.

By analyzing the epidemiological and clinical features of adenovirus in children with acute respiratory tract infection (ARTI), we provide a theoretical basis for early clinical diagnosis and treatment. Nasopharyngeal secretions were collected from 3480 children with ARTI, who were hospitalized at the No. 2 Hospital of Changzhou from January 2011 to December 2012. Adenovirus were detected using direct immunofluorescence assays. A total of 80 samples were positive for adenovirus (2.30%). The rate of adenovirus infection during 2011 was significantly higher than that in 2012, and the infection rate was higher in summer and autumn than in winter and spring. The infection rate was 1.14% among children aged < 1-year-old and the rates were higher among children in other age ranges. Adenovirus was found to be an important ARTI pathogen in children in Changzhou, mainly affecting children older than 1 year. ADV infections have various clinical presentations, but affected children tend to be severely ill with poor outcomes.

The paper reported an investigation of the pharmacokinetics of SN-38 (7-ethyl-10-hydroxy-camptothecin) in rats and the tissue distribution in mice after injection of irinotecan hydrochloride nanoparticles (CPT-11) via tail veins. An LC-MS/MS method was established to determine the concentrations of SN-38 in whole blood of rats and in different tissues of mice. The pharmacokinetics and tissue distribution of SN-38 were compared after the intravenous injection of CPT-11 NPs and CPT-11 solution. Compared with irinotecan solution, the elimination half-life of SN-38 was prolonged from 2.17 h to 2.67 h after the intravenous injection of CPT-11 NPs, but its AUC had little change. After the injection of CPT-11 NPs in mice, over time, the concentrations of CPT-11-metabolized SN-38 in CPT-11 NPs were significantly higher in the whole blood, colon and lungs than those in CPT-11 solution, followed by in the spleen and liver, but those in the heart and brain had no change. However, the amount of SN-38 in the kidneys was reduced with time. CPT-11 NPs could prolong SN-38's (one of its metabolites) blood circulation time in rats and significantly increased the concentration of CPT-11-metabolized SN-38 in the whole blood, colon and lungs of mice. CPT-11 NPs made SN-38 efficiently target-bind to the colon and lungs of mice.

Aim To study the effect of estrogen on the migration of breast cancer cells and the possible underlying mechanisms.Methods Human breast cancer cell lines MCF-7(estrogen receptor, ER+) and MDA-MB-468(ER-) were employed as a model system.Cells were treated with E2 and pretreated with CANP inhibitor(calpeptin)where needed.Wound-healing assay was applied to evaluate cell migration, Western blot assay was performed to observe protein level, and fibronectin expression was silenced by specific siRNA transfection.Results ① Treatmentof MCF-7 and MDA-MB-468 cellswith E2(50 nmol·L-1) increased cell migration by(51.55±5.50) ％(P<0.01)and (40.78±4.78)％(P<0.05), respectively;② E2 significantly up-regulated the expression of FN protein in MCF-7 and MDA-MB-468 breast cancer cells, which was 2.11 times(P<0.05)and 1.86 times(P<0.01), respectively;③ Pretreatment with calpeptin(10 μmol·L-1) decreased E2-induced cell migration by (49.55±6.44)％(P<0.05) in MCF-7 and(36.85±4.40)％ (P<0.01)in MDA-MB-468 cells;④ Calpeptin pretreatment inhibited E2-induced fibronectin up-regulation by(80.12±4.55)％ and(78.84±5.70) ％(P<0.01), respectively;⑤ Knockdown of FN with siRNA suppressed cell E2-induced migration by(40.65±5.80)％(P<0.01)in MCF-7 and(40.88±6.02)％(P<0.05)in MDA-MB-468 cells.Conclusion E2 stimulates the migration of breast cancer cells with or without ER expression and a calpain-FN signaling pathway may be involved in the E2 action.

Objective To study the inhibitory effect of mycophenolate mofetil (MMF) on expression of TGF-? in pulmonary fibroblasts (WI26 cells) and its application value.Methods Pulmonary fibroblasts were divided into control group,MMF group,TGF-? group,and MMF+TGF-? group,after routine culture.Expression of TGF-?-induced COL1A1 was detected by reverse transcriptase-polymerase chain reaction (RT-PCR).Expression of COL1 proteins was detected by Western blot analysis and chloramphenicol acetyl transferase assay,respectively.Difference in contractility of collagen fibers and migration of cells was observed in collagen matrix contraction test and cell scratch test.Results The expression level of COL1A1 mRNA was higher in MMF group than in control group 24 and 48 h after treatment with MMF (77.0%?2.9% vs 38.0%?3.7%),and was lower in MMF group than in control group 24 and 48 h after treatment with TGF-? and MMF+ TGF-? (134.0%?3.1% vs 189.0%?2.4%,and 95.0%?2.7% vs 71.0%?3.3%,P

Referring to the statistical model for the SNP haplotype phasing which was based on the allele frequencies and advised by Browning SR, we investigated and deduced the phasing method of STR haplotype with linkage disequilibrium inpaternity testing preliminarily. Haplotype phasing of two X-STRs in linkage disequilibrium were illustrated. This method provides an idea for the haplotype phasing of STR markers, which is helpful for interpreting the typing results of STR more scientifically and accurately.
