Objective To investigate the sensitivity and specificity of colloidal gold immunochromatography assay in rapid detection of respiratory syncytial virus (RSV)antigen.Methods A total of 197 nasal-pharyngeal swabs (NPs)or nasal-pharyngeal aspirates (NPAs ) obtained from patients were tested by RSV assay kits, i. e., colloidal gold immunochromatography assay.The results determined by reverse-transcription polymerase chain reaction (RT-PCR)were taken as reference.Compared to the results of RT-PCR,the sensitivity of the kit was different when testing different types of specimens or specimensobtained from patients of different ages.Results A total of 95 (48.2%)samples were positive for RSV tested by RT-PCR.The sensitivity and specificity of colloidal gold immunochromatography assay were 34.7% and 100%, respectively compared with RT-PCR results.The positive rate of the assay was higher in testing NPAs than NPs (36.2% vs 8.6%,P < 0.01 ), which was the same in the sensitivity (22.1% vs 12.6%). The positive rate of colloidal gold year old,RT-PCR method should be used for RSV detection in clinical practice to avoid missed diagnosis.

Objective To compare the effectiveness of the forced-air warming system and the conventional warming care practice in preventing hypothermia in patients undergoing major surgeries.Methods A total of 62 patients were enrolled in this study. Patients of both sexes,aged≥18 years,and with an ASA physical status Ⅰ-Ⅲ were included and allocated randomly into intervention group(n=30)or control group(n=32). Patients in the intervention group were provided forced-air warming,either prior to induction or during the surgery procedure depending on core temperature monitoring results. In the control group,patients were warmed with conventional warming care without any intervention. Core temperature was measured by Spot-On sensor and tympanic membrane thermometer,blood pressure,the electrocardiogram,heart rate,pulse oxygen staturation,and partial pressure of end-tidal COwere also monitored continuously in the two groups.Crystalloid,colloid,and allogeneic blood were also recorded by strict protocol. Results Intraoperative hypothermia monitored with tympanic thermometer was observed in 23 patients(71.87%)in the control group,which was significantly higher than that (0) in the intervention group(P=0.00). In addition,the incidence of hypothermia monitored by Spot-On sensor was 81.25%(n=26)in control group and 13.33%(n=4)in intervention group(P=0.00). Conclusion Compared with the conventional warming care,forced-air warming system is more effective in preventing hypothermia during major surgeries.

Objective To explore the clinical significance of two new indexes including approximate entropy of oxygen saturation (SpO2ApEn) and saturation impairment time index (SITi) in assessing the severity of hypoxemia in obstructive sleep apnea hypopnea syndrome (OSAHS) patients.In addition,to investigate the correlation betewwn new indexes and other parameters.Methods The six hour polysomnography (PSG) of 500 patients with OSAHS and snorers in our hospital was retrospectively analyzed.According to the level of apnea hypopnea index (AHI),subjects were divided into four subgroups,namely 113 healthy controls,121 mild OSAHS,118 moderate OSAHS,and 148 severe OSAHA patients.SpO2 ApEn and SITi values among the four groups were compared.the correlations between SpO2 ApEn,SITi and other parameters were analyzed,including AHI,oxygen desaturation index (ODI),the lowest oxygen saturation(LSpO2) and the duration of oxygen saturation lower than 90％ (T ＜ 90％).Next,taking AHI as the gold standard,the significance of SpO2ApEn and SITi in assessing the severity of hypoxemia in OSAHS patients was explored by ROC curve analysis.Results SpO2ApEn and SITi between two each groups were significantly different (P ＜ 0.001) and increased synchronously with AHI.Spearman correlation analysis showed that SpO2ApEn and SITi had a good correlation with AHI (correlation coefficient r =0.765,r =0.678,P ＜ 0.O1).SpO2ApEn and SITi also had a good correlation with ODI,LSpO2and T ＜ 90％.According to the ROC analysis,the Boundary values of SpO2ApEn for mild,moderate and severe OSAHS patients were 16.70,17.81,and 20.03,respectively,and the corresponding SITi values were 3.685,4.055,and 4.445.Conclusion In this study,SpO2ApEn and SITi increased synchronously with AHI,SpO2ApEn and SITi had good correlations with AHI,ODI,LSpO2and T ＜90％.SpO2ApEn and SITi have important clinical significance for assessment of hypoxia severity in OSAHS patients.

OBJECTIVE:To explore the effect of olmesartan on NT-proBNP and high-sensitive C- reactive protein(hs-CRP) and left atrial diameter (LAD) in elderly hypertensive patients with paroxysmal atrial fibrillation (PAF). METHODS:188 cases of elderly hypertensive patients with PAF from May 2011 to May 2013 were divided into control group(n=94)and observation group (n=94),both groups received the treatment of amiodarone,observation group were additionally given olmesartan on the basis of conventional treatment,the treatment cycle was 12 months in two groups. NT-proBNP,hs-CRP,LAD changes and atri-al fibrillation(AF)recurrence were compared between 2 groups before(T0)and after 1 month(T1),3 months(T2),6 months (T3)and 12 months(T4)treatment;related factors for recurrence of atrial fibrillation were analyzed. RESULTS:NT-proBNP and hs-CRP in observation group were lower than control group at T3-T4,with significant difference(P<0.05);LAD improvement in observation group was better than control group,with significant difference (P<0.05). After treatment,the decent range of NT-proBNP and hs-CRP in observation group were higher than that control group,with significant difference(P<0.05);AF re-currence in observation group were lower than control group at T3-T4,with significant difference(P<0.05);Multiple stepwise re-gression analysis showed that NT-proBNP and hs-CRP were positively related with LAD,with significant difference (P<0.05);multi-factor logistic regression analysis showed that the NT-proBNP level,hs-CRP,LAD were positively correlated with AF re-currence,NT-proBNP drop and hs-CRP drop were negatively correlated with AF recurrence. CONCLUSIONS:Serum NT-proB-NP and hs-CRP levels are closely related to LAD and AF recurrence in elderly hypertensive patients with PAF,and olmesartan can decrease the plasma NT- proBNP CRP levels,reduce inflammation response and improve left atrial remodeling so as to re-duce the AF recurrence.

Helicobacter pylori is closely related to many digestive system diseases,such as chronic gas-tritis,digestive ulcer,gastric mucosa associated lymphoid tissue lymphoma and gastric cancer,also leads to chil-dren with iron deficiency anemia,growth retardation,asthma,allergic diseases etc. So it is a key strategy to pre-vent and treat these diseases by eradicating Helicobacter pylori. Due to the increasing rates of antimicrobial resist-ance of clarithromycin and metronidazole,the eradication rate of standard triple therapy is 1ess than 80%in re-cent years. Especially in areas of high clarithromycin resistance and standard triple therapy have not been recom-mended as first-line therapy,it is necessary to investigate a new therapeutic strategy to improve the eradication rate of Helicobacter pylori. The new treatments for eradication of Helicobacter pylori in children is mainly based on sequential therapy,bismuth-based therapy,concomitant therapy and probiotics treatment. This article reviews the research progress of the new treatments in recent years.
