Objective To investigate the clincial value of ELISA combined with colloidal gold immunochromatography in the detection of anti-cyclic citrullinated peptide (CCP) antibody in patients with rheumatoid arthritis (RA).Methods From October 2014 to October 2016,120 patients with RA who admitted to Fuyang People 's Hospital were selected as RA group,and 120 healthy subjects were selected as the control group.Serum samples of patients were collected and tested for anti-CCP antibody by ELISA and ELISA combined with colloidal gold immunochromatography.Results ELISA method was lower than ELISA combined with colloidal gold immunochromatography test (x2 =3.943,P ＜ 0.05).The sensitivity,specificity,positive predictive value,negative predictive value of ELISA combined with colloidal gold immunochromatography assay were 93.33％,91.67％,84.85％,96.49％,respectively,which were higher than single ELISA method (all P ＜ 0.05).Conclusion ELISA combined with colloidal gold imnmunochromatography assay for detection of serum anti-C.CP antibody in patients with RA is effective and can obtain high diagnostic sensitivity and specificity,and it is worthy of promotion.
RESUMO
The parabrachial nucleus (PB)is made up of gray matter around the Pons combination(BC),mainly consisting of glutamatergic,GABAergic and enkephalinergic neurons.PB is connected to hypothalamus and basal forebrain through a network of nerve fibers.Specific lesion of the entire parabrachial complex in animals leads to a deep coma.PB also projects to the non-rapid eye movement(NREM)-related regions including the ven-trolateral preoptic,and receives the projections from the parafa-cial zone.Activation of the GABAergic neurons in parafacial zone can promote NREM sleep,which indicates that PB partici-pates in NREM sleep.Furthermore,the lateral PB is actived when rapid eye movement(REM)sleep is deprived.In conclu-sion,PB participates in regulating wakefulness, NREM and REM sleep.This review summarizes the advances in the roles of PB in sleep-wake regulation.

RESUMO
Objective To investigate effects of different sedation methods on the mechanical ventilation patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods A total of 101 patients with mechanical ventilation in our hospital was randomly divided into observation (58 cases) and control (43 cases) groups.The observation group was given to strengthen psychological care during the day, and the night was given to the patients with AECOPD.The control group was treated with continuous analgesia and sedation, and the daily morning was executed to wake up the plan 1 ～ 2 hours.A set of indexes were observed, including white cell count, C-reactive protein, oxygen index, B-type natriuretic peptide, delirium occurred rate, unexpectedly drawn tube rate, and duration of mechanical ventilation.Results White blood cell number, C reactive protein, and oxygen index group in the observation group were significantly better than the control group [(10.1 ± 2.4) × 109/L vs (11.2 ± 2.8) × 109/L,(40.6 ± 11.6) mg/L vs (45.8 ± 12.2) mg/L, and (285.6 ±45.1) vs (268.2 ±42.6)] (P ＜0.05).The incidence of delirium rate in the observation group was significantly lower than the control group [30/58(51.7％) vs 31/43(72.1％)] (P ＜0.05).The mechanical ventilation time in the observation group was significantly shorter than the control group [(8.41 ± 3.96) d vs (10.35 ± 5.57) d] (P ＜ 0.05).There was no significant difference between B type natriuretic peptide and accidental extubation rate (P ＞ 0.05).Conclusions The night program sedation program can significantly improve AECOPD mechanical ventilation in patients with inflammatory index and oxygen index, reduces the incidence of delirium in patients with acute exacerbation of chronic obstructive pulmonary disease, does not increase the accidental extubation rate, and significantly shortens the AECOPD patients with mechanical ventilation duration of mechanical ventilation, as a mechanical ventilation in AECOPD patients who killed one of the options.
RESUMO
Objective To investigate the effects of hyperbaric oxygen (HBO) therapy on interleukin-1 β( IL-1 β) and interleukin-6 ( IL-6 ) levels in patients with moderate or severe traumatic brain injury ( TBI ) and to analyze its therapeutic efficacy.MethodsOne hundred and fifty-six patients with moderate or severe TBI were randomly divided into a control group and an HBO adjunctive therapy group with 78 cases in each.The control group received essential neurosurgical treatment and conventional drug treatment,and the HBO group was given one HBO therapy session in addition.IL-1 β and IL-6 were quantitatively determined using sandwich ELISA,and the patients'scores on the Glasgow coma scale (GCS) were measured before and after treatment.The Glasgow outcome scale (GOS) was used to evaluate in a follow-up 6 months after injury.ResultsThe average IL-1 β and IL-6 levels of the two groups and their average GCS scores were not significantly different before treatment.After treatment,IL-1 βand IL-6 levels decreased significantly and GCS scores increased significantly in both groups,but there were significant inter-group differences in all three measures.Six months after injury the GOS evaluation indicated that significantly more patients had better outcomes in the HBO group than in the control group. Conclusion Conventional treatment combined with HBO therapy can promote neurofunction recovery in TBI patients.The mechanism may be related to down-regulation of serum IL-1 β and IL-6.
RESUMO
Objective To investigate effects of hyperbaric oxygen (HBO) therapy on C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) levels in patients with moderate or severe traumatic brain injury (TBI)and to analyze its therapeutic efficacy. Methods One hundred and eight patients with moderate or severe TBI were randomly divided into a control group (54 cases) and an HBO adjunctive therapy group (HBO group, 54 cases).Both groups received essential neurosurgical treatment and conventional drug treatment, and the HBO group was given one session of HBO therapy in addition. Serum CRP and TNF-α were detected, and the scores on the Glasgow coma scale (GCS) were measured before and after treatment. CRP was detected by turbidimetric immunoassay and TNF-α using ELISA. Glasgow outcome scale (GOS) scores were evaluated in a follow-up 6 months after injury. Results Average CRP, TNF-α and GCS measurements showed no statistically significant difference between the groups before treatment. After treatment, CRP and TNF-α were significantly lower and GCS scores significantly better in both groups, but patients in the HBO group were, on average, significantly better than the controls on all three measures.Six months later, GOS evaluation gave a significantly larger number of patients with a better prognosis in the HBO group compared with the controls. Conclusion HBO therapy can significantly decrease serum CRP and TNF-α after severe TBI, thus enhancing therapeutic efficacy.

RESUMO
BACKGROUND: Studies have confirmed that RhoA/ROCK signaling pathway plays an important role in the process of epithelial-mesenchymal transition. OBJECTIVE: To investigate the effect of Y-27632 (inhibition of rhodopsin kinase of 4-aminopyridines compounds) on the epithelial-mesenchymal transition of rat peritoneal mesothelial cells (RPMCs) induced by transforming growth factor ?1 (TGF-?1). DESIGN,TIME AND SETTING: An animal observational experiment was performed at the Laboratory of Nephrology in the First Affiliated Hospital of Sun Yat-sen University from March 2007 to March 2008. MATERIALS: A total of ten healthy male Sprague Dawley rats were provided by the Animal Experimental Center of Sun Yat-sen University. Y-27632 was the product of Calbiochem Company (German). TGF-?1 was the product of R&D Company (USA). METHODS: Primary RPMCs were cultured in vitro. After synchronization for 24 hours, RPMCs were randomly divided into 4 groups: control group (RPMCs cultured in the DMEM/F12 without serum), TGF-?1 group (RPMCs cultured in the DMEM/F12 without serum, and then added 10 ?g/L TGF-?1), Y-27632 group (RPMCs cultured in the DMEM/F12 without serum, and then added 10 ?g/L Y-27632), TGF-?1 +Y-27632 group (RPMCs cultured in the DMEM/F12 without serum, and then added 10 ?g/L Y-27632. 2 hours later, 10 ?g/L TGF-?1 were added). The cells were collected 48 hours after culture. MAIN OUTCOME MEASURES: The mRNA and protein expression of E-cadherin and ?-Smooth muscle actin (?-SMA) were measured by RT-PCR. The protein expression level of E-cadherin, ?-SMA and vimentin was measured by Western blotting. RESULTS: Compared to control group, the expression of E-cadherin significantly decreased in the TGF-?1 group, and the expression of ?-SMA and vimentin significantly increased (P
