RESUMO
Objective@#To explore the association between processed food consumption and anxiety symptoms among college students in Yunnan Province, so as to provide a reference for the prevention and treatment of anxiety symptoms in this population.@*Methods@#A cluster random sample of 2 515 first year students from two universities in Yunnan Province was selected to carry out a longitudinal investigation which included a baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The food frequency questionnaire was administered to assess processed food consumption, and the Depression Anxiety Stress Scale-21 (DASS-21, Chinese version) was used to evaluate anxiety symptoms. A generalized estimation equation model was used to analyze the relationship between processed food consumption and anxiety symptoms.@*Results@#The detection rates of T1-T4 anxiety symptoms among college students in Yunnan Province were 29.70%, 36.70%, 37.69% and 38.73 %, respectively, and the corresponding anxiety symptom scores were 4(0,8), 4(0,10), 4(0,12), 2(0,14). After controlling for demographic variables and confounding factors in the generalized estimation equation model, a statistically significant association was found between consumption of carbonated beverages ( β=0.06, 95%CI =0.03-0.08), and other processed snacks ( β= 0.04 , 95%CI =0.01-0.07) ( P <0.05). The stratified analysis by gender showed that the consumption of carbonated beverages ( β=0.08, 95%CI =0.05-0.12) and fast food ( β=0.03, 95%CI =0.00-0.06) was significantly associated with anxiety symptoms in female college students ( P <0.05). There was no significant association between processed food consumption and anxiety symptoms in male college students ( P >0.05).@*Conclusions@#Processed food consumption by college students in Yunnan Province may increase the risk of anxiety symptoms, particularly among female students. There is a need to strengthen guidance in respect to processed food consumption, so as to prevent and treat anxiety symptoms.
RESUMO
Objective To investigate the epidemiological and clinical characteristics and prognosis of 31 children with hand foot and mouth disease(HFMD) complicated with acute flaccid paralysis(AFP).Methods Thirty-one HFMD children complicated with AFP served as study objective,who were admitted to Tangshan Maternity and Children Health Hospital from Jun 2011 to Dec 2014.The clinical manifestations and follow-up outcomes of 31 children with HFMD followed by AFP were retrospectively reviewed.Results Participants in this study consisted of 31 children(16 males,15 females,age from 3 months to 9 years) who met the criteria for HFMD with AFP.Among the 31 cases,27(87.1％)cases were less than 3 years old and 29(93.5％) cases were from countryside.Eleven cases (35.5％)were infected by enterovirus 71,1 case (3.2％) was infected with coxsackieviruses A16 and 19 cases(61.3％) were infected by other enteroviruses.AFP developed(7.1 ±2.9) days after the onset of fever and progressed to maximum severity within 1-2 days.All of the cases presented with fever and skin rash,38.7％ cases presented with limbs tremor and 87.1％ cases presented with startle and skip.Besides AFP of limbs, 100％ cases complicated with encephalitis.Thirty-one cases showed poliomyelitis-like syndrome(20 cases with one flaccid limb,5 cases with lower limbs,4 cases with upper limbs and 2 cases with left hemiplegia).In these cases, the muscle power varied from level 0 to level 4.The muscle strengthen and muscle tone in 21 patients were recovered within 2 weeks,and the other cases showed recovery 2 to 3 weeks later.After four weeks, the muscle strengthen in 19 cases recovered to 5 level(10 cases with single lower limb,5 cases with single upper limb,3 cases with two lower limbs and 1 case with two upper limbs).Conclusion HFMD complicated with AFP most commonly occurs in children aged less than 3 years old.The majority of cases were from countryside.Enterovirus 71 is still relatively common pathogen.All the 31 cases complicated with encephalitis.Cases clinically presented one flaccid limb, lower limbs, upper limbs and hemiplegia.AFP may be to some degree reversible in HFMD cases.In most cases described here, paralysis occurred in a single lower extremity and recovered more rapidly than those with two fimbs affected or with single upper extremity impairment.
RESUMO
Objective To explore the diagnostic value of anti-cyclic citrullinated peptide (CCP) 3.1 IgG/IgA antibody detected by enzyme-linked immunosorbent assay (ELISA) in patients with rheumatoid arthritis (RA).Methods The ELISA was used to measure the anti-CCP3.1 antibody in the serum of 169 RA patients,100 patients with other rheumatic diseases (including systemic lupus erythematosus,Sjogren's syndrome and osteoarthritis) and 72 healthy controls.The diagnostic value of CCP3.1 was assessed and compared with the second generation of anti-CCP IgG (CCP2) antibody,the correlations between anti-CCP3.1 antibody and the clinical and laboratory parameters were analyzed.Two-independent samples t test,chi-square test and Spearman's correlation were adopted for statistical analysis.Results ① The average cut-off concentration of anti-CCP3.1 antibody was (1122±1429) U/ml in RA,(13±14) U/ml in other rheumatic diseases and (6±5) U/ml in healthy controls.② The area under curve of ROC for anti-CCP3.1 antibody and anti-CCP2 antibody were 0.923 and 0.936 respectively.There was no difference between the sensitivity (82％ vs 79％)and specificity (97％ vs 99％) of anti-CCP3.1 antibody and anti-CCP2 antibody.The Kappa values between anti-CCP3.1 antibody and anti-CCP2 antibody was 0.763.③ We also found that anti-CCP3.1 antibody was positive in 20％(7/35) of anti-CCP2 antibody negative,43％(18/42) of RF negative,62％(47/76) of AKA negative,71％(49/69) of APF negative and 13％ of autoantibodies negative patients,indicated that antiCCP3.1 antibody had a potential value in the diagnosis of serum negative patients with RA.④ The presence of anti-CCP3.1 antibody was correlated with RF,HRF-IgG,APF,AKA,GPI and IgA (P＜0.05),except disease activity.Conclusion The sensitivity of anti-CCP3.1 antibody is slightly higher than anti-CCP2 antibody.The Anti-CCP3.1 antibody is a very valuable parameter for the diagnosis of RA,especially in serum negative patients.
