Objecfive To study T cell subsets distribution in peripheral blood from patients with ankylosing spondylitis(AS)and the role of cell immunity in AS.Methods 30 patients with untreated active phase AS and 30 healthy volunteers were enrolled.The expression of CD4+ and CD8+ T cell subsets were evaluated by flow eytome try.The correlation among T cell subsets and Bath AS function index(BASFI).Bath AS measurement index(BASMI),course of disease,age,ESR,hyper-sensitive C-reactive protein (hs-CRP) were analyzed.Results The level of CD4+ T cell and CD4/CD8+ratio were significantly lower than that of healthy volunteers[(29.24±9.22)% vs.(40.09±6.86) %,(0.96±0.49 ) vs.(1.70±0.67 ),P ＜ 0.01 ],and CD8+ T cell were significantly higher than that of healthy volunteers [(32.91±6.86) % vs.(25.60± 5.97 ) %,P ＜ 0.01 ].The level of CD4+ T cell subsets in peripheral blood of AS patients was negatively correlated with BASMI (r =-0.479,P ＜ 0.01 ),and CD8+ T cell subsets were positively correlated with ESR,hs-CRP,BASFI and BASMI ( r = 0.373,0.430,0.462,0.530,P ＜0.05 ).The ratio of CD4+/CD8+ was negatively correlated with hs-CRP,BASFI and BASMI (r = -0.465,- 0.473,- 0.426,P ＜ 0.05 ).CD4+,CD8+,ratio of CD4/CD8 were not significantly correlated with age and course of disease in patients with AS.Conclusion T cell subsets are significantly abnormal in peripheral blood of patients with AS,and the imbalance degree of T cell is correlated with severity and activity of AS,suggesting that T cell subsets imbalance plays an important role in the pathologensis of AS.

BACKGROUND: Chinese medicine Gukang prescription has a clear effect on clinical treatment of osteoporosis, but the therapeutic pathway is stil unclear.
OBJECTIVE:To investigate the effects of Chinese medicine Gukang on the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin by regulating core binding factor alpha 1 expression to control the growth and development of osteoblasts.
METHODS:Sprague-Dawley neonatal rats within 24 hours after delivery were used for the separation and culture of osteoblasts. Adult Sprague-Dawley rats were used to prepare drug-containing serum, and then divided into two groups randomly:normal control group and Gukang group. Rats in the normal control and Gukang groups were intragastrical y administrated with extract of Gukang prescription and normal saline based on rat’s body surface area, for 1 consecutive week. Two hours after the last administration, blood samples were taken from the heart. Then the serum was col ected. Osteoblasts at passage 3 were confirmed with alkaline phosphatase assay and digested. After counting and planting, al osteoblasts were divided into two groups and treated with col ected
serum for 72 hours. Proliferative rate of osteoblasts was detected by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test. Secretion of alkaline phosphatase was detected by using enzyme linked immunosorbent assay and corrected with the corresponding absorbance value. mRNA expression of core binding factor alpha 1, receptor activator of nuclear factor kappa B ligand and osteoprotegerin were detected by using reverse
transcription-PCR in al groups.
RESULTS AND CONCLUSION:mRNA expression of osteoprotegerin and core binding factor alpha 1 in the Gukang group was significantly higher than that in the normal control group, but protein and mRNA expression of receptor
activator of nuclear factor kappa B ligand were dramatical y lower in the Gukang group compared with the normal control group (P<0.01). These findings indicate that Chinese medicine Gukang prescription can modulate the expression of
core binding factor alpha 1, thereby adjusting the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin, which may be one of the mechanisms underlying Gukang treatment for osteoporosis.

To reveal the involvement of oxidative stress in hypertension and insulin resistance. Angiotensin Ⅱ was given to adrenomedullin-knockout mice for 4 weeks. 4-Hydroxy-TEMPOL, a superoxide scavenger mimetic was also employed. The results suggested that adrenomedullin may exert a protective effect against insulin resistance via its intrinsic antioxidant effect.

Objective: To investigate the level of mental health literacy among residents in Jiaxing City, Zhejiang Province, so as to provide insights into implementation of mental health education and improvements of the quality of mental health services. Methods: A total of 2 248 permanent residents at ages of 18 years and older were sampled using a multi-stage stratified random sampling method from 3 streets (townships) in Jiaxing City. Residents' demographics were collected using self-designed questionnaires, and the mental health literacy was investigated using the Mental Health Literacy Questionnaire. Factors affecting the achievement of the target of mental health literacy were identified among residents using a multivariable logistic regression model. Results: A total of 2 248 questionnaires were allocated and 2 172 valid questionnaires were recovered, with an effective recovery rate of 96.62%. The respondents included 1 075 men (49.49%) and 1 097 women (50.51%). There were 623 respondents that met the target of the mental health literacy (28.68%). Multivariable logistic regression analysis showed a higher possibility of achieving the target of mental health literacy levels among women than among men (OR=1.282, 95%CI: 1.047-1.570), among unmarried residents (OR=1.685, 95%CI: 1.018-2.788) than among married residents, among residents with educational levels of junior high school (OR=1.689, 95%CI: 1.168-2.441), high school/vocational high school/technical secondary school (OR=2.420, 95%CI: 1.601-3.658) and college or above (OR=3.543, 95%CI: 2.252-5.574) than among residents with an educational level of primary and below, among students (OR=2.572, 95%CI: 1.013-6.527), medical personnel (OR=3.330, 95%CI: 2.029-5.467), teachers (OR=2.909, 95%CI: 1.202-7.040), freelance/self-employed staff (OR=1.519, 95%CI: 1.100-2.098) and other professional technical personnel (OR=1.529, 95%CI: 1.012-2.310) than among workers. Conclusions The proportion of mental health literacy levels meeting the target is high among residents in Jiaxing City, and gender, educational level, occupation and marital status are factors affecting mental health literacy levels.

Objective: To establish an LC-MS/MS method for the determination of 4-( 4-amino-3-fluorophenoxy )-N-methylpyri-dine-2-carboxamide ( AFP-PMA) as a genotoxic impurity in regorafenib. Methods: The content of AFP-PMA was determined by an LC-MS/MS method. A Waters XBridge Shield RP18 column was adopted to separate the samples and the column temperature was 50℃. The mobile phase consisted of 5 mmol·L-1ammonium acetate aqueous (A)-acetonitrile (B) with gradient elution (0~9 min, 5%B→90%B) at a flow rate of 1. 0 ml·min-1. An electrospray ionization source (ESI) was used in a positive-ion and multiple reactions monitoring mode. The ion channel was m/z 262. 2→244. 1. Results:The standard curve was linear within the range of 2. 41-980. 90 ng·ml-1(r=0. 9998) and the limit of quantification was 8. 02 ng·ml-1. The limit of detection was 2. 41 ng·ml-1, which was e-quivalent to 0.000241% for the concentration of regorafenib. The average recovery was 100.95% and RSD was 2.37% (n=9). Conclusion:The method has good specificity, promising accuracy and high sensitivity, which can be used for determining the trace genotoxic impurity AFP-PMA in regorafenib.

To investigate the role of immediate-early gene c-fos in sodium selenite-induced apoptosis and its position in a possible cascade of apoptogenic genes, we compared the time-courses of expression for 5 related genes, including c-fos, during the apop- tosis induced by sodium selenite with or without blockage of c-fos expression by adding c-fos antisense oligodeoxynucleotide ( ASO) in cultured cortical neurons. The results showed that: (1) in control experiments without c-fos ASO adding, 0. 5 μmol/ L sodium selenite-induced apoptosis as revealed by electrophoretic and flow cytometric examinations; at the same time, sodium selenite also induced down-regulation of bcl-2 mRNA expression and up-regulations of mRNAs related to bax, c-fos, p53, and acetylcholinesterase (AChE) genes; (2) in similar experimental conditions with c-fos ASO cotreatment, the sodium selenite-in- duced apoptosis was blocked with the up-regulation of p53 expression still emerging as before, while the changes in expressions of bcl-2, bax, AChE genes were reversed at the same time. The results suggest that c-fos ASO could play a protective role upon cortical neurons from suffering apoptosis induced by sodium selenite, and there might exist a cascade of gene expressions with p53 and c-fos genes being regulated upstream and then bcl-2, bax, and AChE genes being regulated downstream.

Objective Multiple carboxylase deficiency(MCD) is an autosomal recessively inherited defect of organic acid metabolism.The underlying mechanism is biotinidase(BT) or holocarboxylase synthetase(HLCS) deficiency.The authors reported 15 cases of MCD(clinical characteristics,diagnosis and treatment) and outcomes of long-term follow-up.Methods The clinical data of 15 patients with MCD admitted to Guangzhou Women and Children's Medical Center between Aug.2001 and Feb.2013 were analyzed.The diagnosis was confirmed by urinary organic acid analysis with gas chromatography/mass spectrometry (GC/MS),blood enzymatic determination and gene analysis.The patients consisted of 12 male and 3 female.The onset age ranged from newborn infants to 16 months.Results 1.Remarkable elevations of urinary lactate,3-oxy-butyric acid,3-OH-isovalerate,methylcitrate,3-methylcrontonylglycine,3-OH-propionate were detected in all of 15 cases.Fourteen cases with HLCS deficiency and 1 case with BT deficiency were confirmed by gene analysis.2.Most of patients with HLCS deficiency presented in the neonatal period or early infancy.The main clinical manifestations were skin rash (14 cases),tachypnea (9 cases),developmental retardation (8 cases),vomiting(5 cases),poor feeding (3 cases),developmental regradation (1 case),convulsion (1 case).Laboratory evaluation showed persistent metabolic acidosis and varied degree of ketosis,lactic acidosis,hyperuricacidemia,ammoniemia and hypoglycemia.Biotin was given to 13 patients in 10 mg/d and their metabolic disorders were corrected within 48 h,except one who gave up treatment and died.Treatment with Biotin in 5 mg/d provided clinical stability and normal neurodevelopmental outcome on follow-up for 3-11 (6.47 ± 2.70) years.3.One patient with BT deficiency presented with severe neurological symptoms(impaired consciousness,limbs trembling,tachypnea with irregular respiratory rhythm) at 16 months old.Demyelination of corpus callosum was evident on magnetic resonance imaging.Biotin treatment was given to him on the second of onset,and 1-year follow-up indicated significant improvement of his clinical symptoms,but the right limb weakness did not completely recover.Conclusions The main clinical features of HLCS deficiency include frequent skin rash,tachypnea,and metabolic disorders.BT deficiency may produce variable neurologic manifestations including demyelination of corpus callosum.Urinary organic acid analysis with GC/MS is critical to the early diagnosis of MCD.Prompt biotin treatment is recommended to correct metabolic derangements and continued therapy is essential to the improvement of long-term prognosis.Delayed commencement of therapy in BT deficiency can result in irreversible neurological damage.
