1.Advances in Study on Cytapheresis in Treatment of Inflammatory Bowel Disease
Chinese Journal of Gastroenterology 2016;21(12):755-758
Inflammatory bowel disease(IBD)is a chronic nonspecific intestinal inflammatory disease and the etiology and pathogenesis are not fully clarified. Studies showed that immune factors play an important role in the pathogenesis of IBD. Cytapheresis(CAP)is a new blood purification method which can selectively filter or adsorb the inflammatory cells and cytokines in systemic circulation. Many studies confirmed that CAP had some therapeutic effect on IBD. This article reviewed the advances in study on CAP in treatment of IBD.

Objective To investigate the serum level of visfatin, C-reactive protein (CRP) and monocyte chemoattractant protein-1 (MCP-1) in patients with polycystic ovarian syndrome (PCOS), and provide the basis for understanding the pathogenesis of PCOS. Meth-ods 94 patients with PCOS and 100 healthy subjects were divided into 4 subgroups according to their body mass index(BMI), including obese PCOS subgroup(n = 52), non - obese PCOS subgroup (n = 42), obese healthy subject subgroup (n = 43) and non - obese healthy subject (n = 57). Serum visfatin, CRP, MCP-1, sex hormone levels and metabolic parameters were measured by enzyme-linked immu-nosorbent assay (ELISA), automatic chemistry analyzer or chemiluminescent immunoassay. Results Serum levels of testosterone (T), lu-teiizing hormone (LH) and prolactin (PRL) in the PCOS group were significantly higher than those in healthy subjects group(P <0.05~0.01), and follicle-stimulating hormone (FSH) levels were significantly decreased in PCOS group(P<0.01). Serum levels of Visfatin, CRP, MCP-1,fasting insulin(Fins) and insulin resistance homa model (HOMA-IR) in the obese or non - obese PCOS subgroup were signif-icantly increased than that in the obese or non - obese healthy subjects subgroup respectively (P<0.01). Pearson correlation analysis showed that the visfatin, CRP and MCP-1 levels were positively related to BMI, FINS and HOMA-IR(r=0.323~0.675, P<0.01). Par-tial correlation showed that serum visfatin levels were correlated with HOMA-IR(r=0.491, P<0.01), and serum MCP-1 levels were cor-related with LH (r=0.267, P<0.05) in the PCOS group. Conclusion The patients with PCOS had higher visfatin, CRP and MCP-1 lev-els, and visfatin levels were positively correlated with insulin resistance. Obesity were involved in the chronic inflammation course in patients with PCOS.

BACKGROUND: The incidence of mental problems in adolescents is increasingly higher and has gradually become an important factor affecting their health and growth.OBJECTIVE: To probe into the mental health status and its influencing factors in adolescents in some cities and rural areas in Hubei Province.DESIGN: Clustering stratified random sampling, cross-sectional survey.SETTING: Department of Maternal, Child and Adolescent Health, Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: According to the selected investigation spots of National Surveillance of Constitution and Health of Students, we selected representative urban areas (Wuhan City and Huangshi City) and rural areas (Yun County, Xiantao City, and Xiaogan City) in Hubei Province as sample spots. Totally 1 498 adolescents, aged 16-18 years, were surveyed by clustering stratified random sampling. There were 605 adolescents in urban group and 893 in rural group.METHODS: The self-made survey scale was used to investigate general conditions, such as age, parents' occupation and educational level, family type, social atmosphere, school type and atmosphere, and interpersonal relationship. Symptom Checklist-90 (SCL-90) was used to determine the adolescents' mentalhealth status; 9 subscales (somatization, obsessivecompulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychosis) were set as the observation indexes. SCL-90 is an inventory which is rated on a 5-point scale. Factor score of SCL-90 ≥ 3 or total score ≥ 160 was considered mental disorders. The family educational pattern was investigated through Egma Minnen av Bardndosnaupporstran(EMBU) by questionnaires. It contained positive rearing pattern and negative rearing pattern. Positive rearing pattern (namely, affectional warmth and understanding) contributes to mental health, while negative rearing pattern (e.g. punishment, firm control, excessive interference, partialism or rejection, denial and excessive protection) is adverse to mental health. The family environment was investigated with Family Environment Scale(FES). Four subscales (intimacy, conflict, intellectual-cultural orientation, and positive-recreational orientation) with high reliability and validity were set as indexes. All participants were given unified instructions and required to fill in anonymous questionnaires. The questionnaires were then collected by the teacher in charge of the class.Some indexes of adolescents in the urban and rural areas were observed including the score of SCL-90 and its relation with general conditions,parental rearing pattern and family environment quality. The total scores of symptom checklist 90 were set as dependent variables for stepwise regression analysis of related factors.MAIN OUTCOME MEASURES:①The incidence of mental health ,gender and regional difference of adolescents in some cities and rural areas in Hubei province; ②The score of SCL-90 and its comparison with national norm;③Correlation analysis of the total scores of SCL-90 with general condition and parents' educational type.RESULTS: ① The general incidence of mental disorders was 18.13 % in the 1 498 adolescents in Hubei province. It was 18.20% in boys and 18.04% in girls with no significant difference (P > 0.05). Regional differences: The incidence in rural areas [23.74% (212/893)] was significantly higher than that in urban areas [16.69% (101/605), P < 0.05]. Among all kinds of mental disorders, compulsion, interpersonal sensitivity, hostility,paranoid ideation, and depression were more common. ② Comparison with the national norm: The factor scores of SCL-90 and family environmentalquality were significantly lower that those of the national norm.③ Single factor analysis: The total score of SCL-90 was obviously correlated with age, gender, parents' educational level and expectation, and school atmosphere (P > 0.01). It was negatively correlated with positive rearing pattern (affectional warm, understanding) (P > 0.01), but positively correlated with negative rearing pattern (punishment, firm control, excessive interference,partialism or rejection, and denial). It had significant positive correlation with conflict and significant negative correlation with intimacy, intellectualcultural orientation and positive-recreational orientation(P > 0.01).④Multiple factor analysis: The mental health status of the students was closely related to age, gender, parents' educational level and expectation, interpersonal sensitivity as well as school atmosphere, parental rearing pattern,and quality of family environment.CONCLUSION: The incidence of mental problems in adolescents in some urban and rural areas in Hubei Province is relatively high. Score factors of SCL-90 are all higher than those of the national norm and the mental health level is poor. This has obvious correlation with family factors including age, gender, parents' educational level and expectation, and school atmosphere. Moreover, the quality of family environment and parental rearing pattern are the major factors affecting their mental health.

Objective To study the diagnosis, treatment and prognosis of mixed thyroid malignant tumors. Methods Clinical data of 7 cases with merged different histological types of thyroid malignant tumor treated from January 1977 to December 2006 were retrospectively analyzed. Results Merged different histologic types of thyroid malignant tumor accounted for 0. 14% of all thyroid malignant tumors treated during this period. Preoperative imaging and laboratory data had no specific value in the diagnosis of this merged different histologic types of thyroid malignant tumors. Radical resection in combination of hormonal therapy and 131I radiotherapy achieved a satisfactory result, though thyroid malignant tumor combined with thyroid cancer usually predict a poor prognosis. Conclusions Merged different histologic types of thyroid malignant tumor is a rare clinical entity, with the pathogenesis being obscure and no consensus of opinion on its nomenclature. The prognosis depends on the highest ~ade among an individual group of malignant tumors.
