Objective To explore the characteristics of illness attribution of outpatients with multiple somatic symptoms in Peking Union Medical College Hospital. Methods It was a cross-sectional study conducted from March to October,2012. A total of 150 outpatients were recruited from the departments of Gastroenterology,Traditional Chinese Medicine and Psychological Medicine by convenience sampling. Somatic symptom scale of the Patient Health Questionnaire (PHQ-15) was used to screening each patient in the waiting list. With the cut-off value of 10,patients were divided into the somatic symptom positive (SOM+) group and somatic symptom negative (SOM-) group. Sociodemographic characteristics were compared between these two groups. All the subjects completed interviews including questions about illness attribution. All the answers of illness attribution were concluded into three major groups as physical factors,situational factors and psychological factors. Results The proportion of female was significantly higher in SOM+ group than in SOM-group (69.3% vs. 53.3%;χ=4.048,P=0.044). In SOM+ group,significantly more patients contributed their illness to psychological factors (64.0% vs. 45.0%;χ=5.273,P=0.022). There was no significantly difference between SOM+ group and SOM-group on the phenomenon of multiple illness attribution (41.0% vs. 32.0%;χ=1.407,P=0.236). However,in the Department of Gastroenterology,there were significantly more outpatients in SOM+ group with multiple illness attribution (60.0% vs. 32.0%;χ=3.945,P=0.047).Conclusions The outpatients in general hospital with multiple somatic symptoms are more likely to contribute their illness to psychological factors. The phenomenon of multiple illness attribution is common among patients. Clinicians should increase their awareness and knowledge of illness attribution,so as to provide better holistic health services.

Objective:To evaluate the validity and reliability of the Problem Area in Diabetes Scale (PAID) for assessing diabetes-related distress in patients with type 2 diabetes. Methods:Totally 203 outpatients with type 2 diabetes from a tertiary hospital in Beijing were selected. They were assessed with PAID,Hamilton Depression Scale (HAMD-17),Patient Health Questionaire-9(PHQ-9),World Health Organization Five item Well-Being Index (WHO-5 ),Mini-International Neuropsychiatric Interview (MINI)and HbA1 C. Item analysis and exploratory factoranalysis were conducted to test constructive validity. Concurrent validity was evaluated by the correlation coeffi-cients with the other instruments mentioned above. Totally 3 1 subjects were retested 4 weeks later to obtain the test-retest reliability. Results:Exploratory factor analysis produced 4 factors,including emotional,therapeutic,diet and perceived society support problems specific to diabetics. The total variance contribution ratio was 64. 33%. Except i-tem 7 and 20,no item was across two factors. The correlation coefficients of each item with relevant subscale score ranged from 0. 67 to 0. 86. The PAID scores were positively correlated with the scores of HAMD-17,PHQ-9 and HbA1C (r=0. 48,0. 43,0. 21,P<0. 001 or 0. 01),and negatively correlated with WHO-5 scores (r=-0. 46,P<0. 001). The Cronbach's αcoefficients were 0. 94 for the total scale and 0. 81 -0. 88 for the 4 subscales. The test-retest reliability coefficient was 0. 65 for the total scale and 0. 53-0. 73 for the 4 subscales. Conclusion:The validi-ty and reliability of the Problem Area in Diabetes Scale are acceptable in Chinese mainland,and can be available to assess the stress related to diabetics.

Objective:
Apolipoprotein E (ApoE) is mainly synthesized in the liver. So far, it is unknown the relationship among APOE gene polymorphisms and WML, brain atrophy. Therefore, the aim of the study was to assess the associations of APOE gene polymorphisms in patients with WML and brain atrophy.
Methods:
A total of 58 patients with WML, 128 patients with brain atrophy, 112 patients with co-occurrence of WML and brain atrophy and 95 healthy elderly volunteers were recruited from Renmin Hospital of WuHan University.
Results:
Allele E3 was the most common allele. The alleles E2 had significantly higher levels of ApoB and lower age in WML group. The alleles E2 was associated with the lower level of ApoB, LDL-Ch, TCh, and sdLDL in co-occurrence group. The E3/E3 genotype has higher level of sdLDL, but lower age and female frequency in WML. The E3/E4 genotype had higher level of TG, but lower age in WML. Gender, Age, E2, Hyperhomocysteinemia and UA were also significantly associated with disease progression.
Conclusion
This study found that clinical data, lipids and metabolic complications were closely related to ApoE genotypes and alleles, and also disease progression and type.

This study aims to develop an improved cell screening system for farnesoid X receptor (FXR) agonists based on a dual luciferase reporter gene system. FXR response element (FXRE) fragments from FXR target genes were cloned and inserted into upstream of firefly luciferase (Luc) gene in the plasmid pGL4-luc2P-Hygro. In combination with the internal reference plasmid containing renilla luciferase, a dual luciferase reporter gene system was developed and used for high throughput screening of FXR agonists. After studying the effects of over-expression of RXR, mouse or human FXR, various FXRE fragments, and different ratio of FXR plasmid amount to reporter gene plasmid, induction efficiency of the screening system was optimized by the known FXR agonist GW4064, and Z factor for the system reached 0.83 under optimized conditions. In summary, an improved cell screening system based on double luciferase reporter gene detection system was developed to facilitate the discovery of FXR agonists, where a new enhanced FXRE element was formed by a superposition of multiple FXRE fragments from FXR target genes, instead of a superposition of traditional IR-1 (inverted repeats-1) fragments.

Objective To investigate the expression level of neutrophil extracellular traps (NET) in the peripheral blood and liver tissue of primary biliary cholangitis (PBC) patients and its correlation with clinical biochemical parameters. Methods A total of 24 PBC patients who were admitted to Renji Hospital, Shanghai Jiao Tong University School of Medicine, from August 2016 to August 2020 were enrolled, as well as 8 patients with primary sclerosing cholangitis (PSC) and 19 patients with autoimmune hepatitis (AIH) matched for age, and 19 healthy individuals were enrolled as healthy control group (HC group). The serum level of myeloperoxidase (MPO) was measured, and its correlation with clinical indices were analyzed. Immunofluorescence assay was used to measure the expression of NET in the liver of PBC patients, and an in vitro experiment was to compare the ability of peripheral blood neutrophils to produce NET between PBC patients and healthy controls. Normally distributed continuous data were expressed as mean±standard deviation, and the independent samples t -test was used for comparison between two groups; for the non-normally distributed continuous data expressed as M ( P 25 - P 75 ), the Kruskal-Wallis H test was used for comparison between multiple groups, and the Mann-Whitney U test was used for comparison between two groups. A correlation analysis was performed for MPO level and liver-related laboratory markers, and the Spearman's correlation coefficient was calculated. Results The serum level of MPO in the PBC group was increased to 811.21 (450.67-1 216.20) ng/mL, which was significantly higher than that in the AIH group [468.58 (142.63-812.43) ng/mL] and the HC group [357.54 (203.52-811.21) ng/mL] ( P < 0.05), suggesting that there was a significant increase in the production of NET in peripheral blood of PBC patients. The PSC patients had a serum MPO level of 763.56 (489.59-1 633.14) ng/mL, which was significantly higher than that in the HC group ( P < 0.05). MPO level was positively correlated with alkaline phosphatase ( r =0.500, P < 0.05), gamma-glutamyl transpeptidase ( r =0.426, P < 0.05), alanine aminotransferase ( r =0.521, P < 0.05), and aspartate aminotransferase ( r =0.547, P < 0.01). Confocal immunofluorescence showed colocalization of H3Cit and MPO in the liver of PBC patients. In vitro experiment showed that compared with the HC group, the PBC group had an increase in NET produced by peripheral blood neutrophils after in vitro stimulation and an increase in spontaneous production of NET. Conclusion There is an increase in NET in peripheral blood and liver of PBC patients, and the content of peripheral blood NET is positively correlated with biochemical parameters of liver function. NET may become a novel biomarker for assessing the severity of PBC.
