Objective To explore the relationship between metabolic syndrome and ApoA5 gene polymorphism and serum concentration. Methods 100 patients with metabolic syndrome(MS group) and 100 healthy people(control group) were enrolled in this study. The ApoA5 serum concentration of two groups were measured by using enzyme-linked immunosorbent assay(ELISA), the genotypes of ApoA5-1131T＞C polymorphism were analyzed by polymerase chain reaction-restriction fragment length polymorphism, and fasting blood glucose (FBG), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL) and white blood cell, hemoglobin,platelet, liver and kidney function were measured. Results MS group was compared with control group. In MS group, the ApoA5 serum concentration was significantly lower[(96.68±18.09)ng/ml vs (128.32±23.78)ng/ml,P＜0.01], while the triglycerides levels were obviously higher[(2.35±1.07)mmol/L vs (1.62±1.13)mmol/L,P＜0.01], and ApoA5-1131C allele frequency was higher than that in control group (30% vs 16.5%,P＜0.05). Conclusions The ApoA5 serum concentration in metabolic syndrome was decreased, and ApoA5-1131C was associated with metabolic syndrome.

A novel molecularly imprinted polymers (MIPs) was prepared based on multiwalled carbon nanotubes (MWNTs) by using chlorogenic acid as template, methacrylic acid(MAA) as the functional monomer, and ethylene glycol dimethacrylate (EGDMA) as the cross-linker. Infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis were employed to characterize the composite structure and morphology, the results showed that a stable imprinted layer was grafted on the MWNTs with the average thickness of 30-40 nm. The dynamic adsorption and static adsorption experiments were also executed and the results showed that two kinds binding sites with the maximum apparent binding constant 21.5 μmol/g and 32.7 μmol/g existed v.i. between the imprinted polymers and chlorogenic acid. As solid phase extraction (SPE) materials, the separation and enrichment of chlorogenic acid from honeysuckle were successful with a enrichment factor of 25.

Objective To analyze the CT findings of tuberculous lymphadenitis in parotid gland, so as to improve the diagnostic accuracy of tuberculosis of parotid gland. Methods Nine cases with tuberculous lymphadenitis in parotid gland confirmed by surgical pathology and acid-fast bacilli after preoperative spiral CT plain scan and two phases dynamic enhancement scan were retrospectively analyzed.Imaging findings of CT were reviewed and compared with surgical pathology. Results Seven of the 9 cases of tuberculosis of the parotid gland occurred in the left side, and 2 in the right side, and superficial lobe involvement occurred in 8 cases and deep lobe in 1 ease. The lesion was classified as tumour type (8 cases)and infiltration type (1 case). In tumour type, the number of lesion was from 1 to 4, and the size was from 2.7 to 5.3 cm in diameter. One case of infiltration type measured 3.4 cm in diameter. On CT plain scan,the lesions showed homogeneous slight high-density with regular edge in 5 cases and irregular low-density in 4 cases, and 2 of them with partly blurred edge. On CT enhanced scan, uniform moderate enhancement was seen in 3 cases, circular enhancement in 4 cases, inhomogeneous enhancement in 1 case, and lace-like enhancement in 1 case. Local infiltration occurred in 6 cases. Lymphadenovarix in the same side of lesion occurred in 2 cases. Conclusion CT findings of tuberculous lymphadenitis in parotid gland present diversification, which correlate well with pathological changes. Understanding of characteristic CT findings of tuberculous lymphadenitis in parotid gland is helpful for differential diagnosis, but final diagnosis still depends on pathology and acid-fast baeilli.

OBJECTIVE:To explore the application of topic model in the study of type 2 diabetes treatment plan. METHODS:Clinical data of 650 inpatients with type 2 diabetes in our hospital during Jan. 2012-Jun. 2016 were analyzed retrospectively. The data of clinical diagnosis,lab indexes and clinical drug use were exchanged,summarized and merged by MATLAB R2014a software.
