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.

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. Latent Dirichlet allocation and author topic model were adopted to extract the typical topics with topic probability value>0.1,and the topics was described by the complications with cumulative probability value>0.5. RESULTS:A total of 62 complications words,16 abnormal laboratory indexes groups and 20 treatment plans were obtained. A total of 4 typical topics were excavated(cumulative probability values for the first few complications were 0.8786,0.8247,0.8215,0.7536;topic probability value were 0.3364,0.2773,0.2035,0.1176,respectively) and were mainly characterized by peripheral neuropathy,peripheral vascular disease,abnormal lipid metabolism and microvascular lesions;abnormal lab indexes groups met the above characteristics. The complications with high distribution rate included diabetic peripheral neuropathy (0.5787), hypertension (0.3631),atherosclerosis (0.2789),hyperlipidemia (0.4578) and diabetic retinopathy (0.3143);main drugs included Insulin aspart injection,Insulin injection,Methylcobalamin dispersible tablets,etc. CONCLUSIONS:The complications of type 2 diabetes are characterized by peripheral neuropathy,peripheral vascular disease,abnormal lipid metabolism and microvascular lesions. The medication rules with clinical significance can be extracted from the clinical data by topic model.

Objective To analyze the relationship between the measured diameters of pituitary gland on MRI and peak-stimulated growth hormone(GH) in children with growth hormone deficiency (GHD).Methods A total of 46 children with GHD were included in this study, and 30 healthy children who were admitted to the hospital for health check-up were acted as the control group during the same period.The measured diameters of pituitary gland on MRI were compared between the two groups and the correlation between the diameters of pituitary gland on MRI and peak-stimulated GH were analyzed.Results ① The coronary and sagittal heights of pituitary gland on MRI were greater in children aged 7-10 years old and older than 10 years in control group and in children older than 10 years in observation group than those in children younger than 6 years (P<0.05).The anteroposterior diameter of pituitary gland on sagittal MRI in the control group was increased (P<0.05).The coronal height, sagittal anteroposterior diameter and sagittal height were lower in the observation group compared with age-and gender-matched controls(P<0.05).②The peak-stimulated growth hormone levels were higher in children aged 7-10 years old and older than 10 years in both groups compared with children younger than 6 years old (P<0.05).The peak-stimulated GH were lower in observation group compared with age-and gender-matched controls(P<0.05).③ The heights of pituitary gland on coronary and sagittal MRI in children with GHD were positively related to the peak-stimulated GH, and coronary height had the highest correlation(P<0.05).Conclusion The heights of pituitary gland on coronary and sagittal MRI in children with GHD are positively related to the peak-stimulated GH.The growth and development of children can be predicted by monitoring the changes of GH levels.

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.
