Soluble ST2 ( sST2 ) is protein of interleukin-1 ( IL-1 ) receptor family present in the blood which have been identified has the ability to capture IL-33, thereby inhibiting IL-33/ST2 signaling, the mechanical properties overload of myocardial cells was significantly increased .Thus, when at the onset of heart failure or chronic heart failure deteriorated , or at scarring resulted by myocardial infarction , soluble ST2 can be detected in the blood .The purpose of this review is to discuss the role of soluble ST 2 ( sST2) as a new cardiovascular marker.

OBJECTIVETo study the anti-halitosis effect of sugar-free chewing gum through their influence on odor induced by cysteine.

METHODSTen volunteers were randomly divided into the treatment group and the untreated group; each group consisted of five volunteers. All volunteers consented to participate in a test in which breath odor was induced by cysteine. After the test, the treatment group chewed sugar-free chewing gum for 1 min, whereas the untreated group did not undergo any treatment. The effectiveness was determined by the percent reduction of H2S, CH3SH, and (CH3)2S response after the volunteers chewed gum for 1, 10, and 20 min.

RESULTSAt 1, 10, and 20 min, H2S of the treatment group was reduced by 82.68%, 92.27%, 97.47%, respectively, CH3SH was reduced by 65.49%, 73.79%, and 82.89%, respectively, and (CH3)2S was reduced by 60.45%, 73.82%, and 59.72%, respectively. The differences between the two groups at different times were significant (P < 0.05).

CONCLUSIONChewing gum can effectively inhibit cysteine-induced odor.

[Objective] To investigate the relationship of thyroid hormones with excess-heat syndrome and deficiency-heat syndrome. [Methods] Serum levels of thyroid hormones and thyroid-stimulating hormone (TSH) in 30 healthy volunteers (Group A) , 27 cases of excess-heat syndrome (Group B) and 35 cases of deficiency-heat syndrome (Group C) were detected by radioimmunoassay. [Results] Serum levels of triiodothyronine (T3) and thyroxine (T4) were higher and reverse T3 (rT3) lower in Group C than those in Group A (P 0.05). [Conclusion] Serum thyroid hormones level in deficiency-heat syndrome is different from that of excess-heat syndrome may be related to the hypothalamus-pituitary-thyroid function.

Objective To evaluate the efficacy of topical anesthesia with inhaled aerosolized lidocaine during tracheal intubation under the guidance of fiberoptic bronchoscopy (FOB) in patients with cervical cord injury complicated with high paraplegia. Methods Sixty-four patients with cervical cord injury complicated with high paraplegia were randomly divided into 2 groups ( n = 32 each): group Ⅰ aerosol inhalation and group Ⅱ spray and cricothyroid membrane puncture. In group Ⅰ aerosolized 2% lidocaine was inhaled. In group Ⅱ after the pharynx and larynx was sprayed with 2% lidocaine, cricothyroid membrane puncture was performed and then 2% lidocaine 2 ml was injected. Midazolam 0.01 mg/kg and fentanyl 1 μg/kg were injected iv in both groups 15 min before tracheal intubation guided by FOB. During tracheal intubation guided by FOB, the intubation condition was assessed, and MAP, HR, ECG and SpO2 were monitored. Results The satisfactory rate of intubation condition and success rate of intubation under the guidance of FOB were significantly higher, and the incidences of arrhythmia and bad memory lower in group Ⅰ than in group Ⅱ ( P ＜ 0.05). Conclusion The topical anesthesia with inhaled aerosolized 2% lidocaine is helpful for improving the FOB-guided tracheal intubation condition, and can reduce the occurrence of adverse effects in patients with cervical cord injury complicated with high paraplegia.

Objective To explore the effects of repetitive transcranial magnetic stimulation (rTMS) on cognitive ability in patients suffering from mild cognitive impairment (MCI) after ischemic stroke.Methods Forty five ischemic stroke survivors with MCI but not meeting the criterion for diagnosis as dementia were recruited, and were randomly assigned into an rTMS group (32 patients) and a control group (30 patients) according to a random number table.Both groups received the routine drug therapy of medicine and cognitive function training, and the rTMS group was additionally given rTMS over the left dorsolateral prefrontal cortex at 5 Hz and 80％ motor threshold.The treatments lasted for 4 weeks.The Montreal Cognitive Assessment (MoCA) and auditory event related potential (ERP) were tested for both group before and after the treatment.Results After the treatment, two groups showed significant improvements in the average score of MoCA compared to that before the treatment, and that of the rTMS group was significantly higher than that of the control group.For both groups, the P300 latency shortened and the amplitude increased after the treatment.Moreover, the latency and amplitude of the rTMS group increased to 355.67 ± 16.43 ms and 8.69 ± 1.65 μV, respectively, after the treatment, significantly shortened and lengthened than that of the control group [(372.76 ± 23.35 ms and 7.03 ± 3.04 μV), respectively].Conclusions rTMS can significantly improve the cognitive ability of ischemic stroke survivors in a relatively safe way.

Objective To investigate the application of non-invasive ventilation in children with airway obstructive diseases,especially those who had obstructive sleep apnea syndrome(OSAS).Methods A case follow-up study was conducted between October 2005 and October 2013 in children who had airway obstruction that led to OSAS or chronic respiratory failure and had been given non-invasive ventilation therapy.Children received non-invasive ventilation support,and pressure titration was performed manually in the sleep center while the mode was chosen according to their disease condition.Pulse rate,oxygen saturation or polysomnography were monitored during the treatment.Some patients went on receiving ventilation support when discharged home depending on their disease status.Patients were followed up every 3,6,or 12 months.Results Thirty-seven patients received non-invasive ventilation treatment till October 2013.Thirty-two cases were boys,and 5 cases were girls.The age ranged from 1 year old and 2 months to 12 years old and 6 months.The underlying diseases included OSAS with adenotonsillar hypertrophy,OSAS with mucopolysaccharidosis,mental retardation,cerebral palsy,morbid obesity,and bronchiolitis obliterans.All the OSAS patients had their snoring and apneas relieved,and respiratory distress and daytime symptoms were improved.Regarding the sleep study parameter,the apnea hypopnea index (P ＜ 0.001),obstructive apnea index (P =0.001),oxygen desaturation index(P =0.001),minimum oxygen saturation (P ＜ 0.001) were improved.Till the end of the study,18children (49％)were still receiving non-invasive ventilation,9 children (24％)stopped ventilation after discharge home,4 children (11％)ceased treatment as their symptoms disappeared and polysomnography data was normal,4 children (11％) lost follow-up 3 months after treatment,and 2 children (5％) died of underlying disease.Conclusions Some children with airway obstruction need non-invasive ventilation support.Non-invasive ventilation therapy can be successfully performed in pediatric population.

Objective To evaluate the application value of the micro movement sensitive mattress sleep monitoring system(MSMSMS) in the diagnosis of children with obstructive sleep apnea syndrome (OSAS).Methods One hundred and twenty-nine children aged from 3 to 14 years who visited the sleep center of Beijing Children's Hospital Affiliated to Capital Medical University from June 2013 to June 2015 due to sleep snoring were enrolled.Children with acute respiratory infection,cranial facial abnormalities,chronic lung diseases and neuromuscular diseases were excluded.According to the criteria,36 children were diagnosed as OSAS with average age of (7.3 ± 2.5) years,including 28 males and 8 females.Ninety-three non-OSAS children were recruited with average age of (6.3 ± 2.3) years,including 61 males and 32 females.Subjects were monitored with polysomnography(PSG) and MSMSMS simultaneously.Apnea/hypopnea index (AHI) ＞ 5 or obstructive apnea index (OAI) ＞ 1 were used to define whether OSAS existed.The consistency between MSMSMS and PSG in the diagnosis of OSAS and the determination of sleep efficiency were compared.Results The Kappa consistency coefficient of MSMSMS and PSG in the diagnosis of OSAS was 0.70(95％ CI:0.57-0.84),Z =7.99,P ＜ 0.000 1,which indicated the consistency between PSG and MSMSMS was good.The consistency of sleep efficiency of MSMSMS and PSG were compared.Bland-Altman results showed that there were 3％ (5/129 cases)points out of 95％ consistency bound and the interclass correlation coefficient (ICC) was 0.69 which indicated the consistency of 2 methods was good in determination of sleep efficiency.MSMSMS was able to detect respiratory event that was associated with sub-cortical arousals with no electroencephalogram arousal or blood oxygen reduction.Conclusions There is an adequate consistency between MSMSMS and PSG in the diagnosis of children with OSAS and determination of sleep efficiency.The MSMSMS has an advantage in detection of sub-cortical arousals and respiratory event.
