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 explore the effect of applying problem-based learning(PBL)in clin-ical anesthesiology demonstration for clinical undergraduates. Methods Eighty-nine 2009 clinical undergraduates were divided into two groups:experimental group and control group. Students in ex-perimental group received PBL while those in control group received traditional teaching. The effect was evaluated according to the results of case examination and investigation table. The results were analyzed by X2 test. Results Most students (42/45) answered questions correctly in experimental group while only 30 of 44 students(30/44)did in control group(P<0.05). Concerning the results of investigation,PBL had more advantages than traditional teaching method in the following 5 aspects:self-studying ability(86.7%,39/45),clinical thinking ability(73.3%,33/45),information seeking ability (75.6%,34/45),expressing ability (82.2%,37/45),communicating between students (75.6%, 34/45)(P<0.05). Conclusions PBL has evident advantages in anesthesiology clinical demonstration. It can inspire students,cultivate abilities,enhance critical thinking and finally improve teaching effect.

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.

AIM: To demonstrate the effects of telmisartan on the proliferation and apoptosis of U937 cells.METHODS: The proliferation ability of the U937 cells was assessed by CCK-8 assay and colony formation test with methylcellulose.The CD11b expression rate of the U937 cells was identified by flow cytometry.The apoptotic rate was analyzed by flow cytometry with Annexin V-PI double staining and Hoechst 33342 staining.The protein levels of cleaved PARP and cleaved caspase-3 were determined by Western blot.RESULTS: The results of CCK-8 assay confirmed that the viability of U937 cells was inhibited by telmisartan.The colony formation capacity of U937 cells was also significantly inhibited by telmisartan.The differentiation of U937 cells was induced by telmisartan with the expression of CD11b.The results of flow cytometry analysis with Annexin V-PI double staining and Hoechst 33342 staining identified that the apoptosis of U937 cells was induced by telmisartan in dose-dependent and time-dependent manners with the up-regulation of cleaved PARP and cleaved caspase-3 proteins.CONCLUSION: Telmisartan inhibits the proliferation and induces the differentiation of U937 cells.Telmisartan also induces the apoptosis of U937 cells through the caspase pathway.

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 investigate the effects of Compound Zhe Bei granule (CZBG) combined with doxorubicin on the expression of GST and Topo - Ⅱ in K562/A02 cell line multidrug resistance tumor xenografts in mice. Methods Tumor xenografts model was established by injecting the multidrug resistance cell line K562/A02 in the axillary flank of BALB/c - nu - nu mice. Drug - comgbination of CZBG intragastric administration and doxorubicin intraperitoneal injection ( i. p. ) was given to the BALB/c - nu nude mice. The tumor xenografts were made into slice after the dissection, and the expression of GST and Topo - Ⅱ in K562/A02 tumor xenografts in mice was investigated by immunohistochemical technique. The integral optical density (IOD) of GST and Topo- lⅡ in K562/A02 tumor xenografts was measured by Image ProPlus 6.0. Results Compared with the single treatment of doxorubicin i. p group,the combination of the doxorubicin and CZBG with dosage classified by three types( high, middle, low) can decrease IOD of GSH and Topo - Ⅱ in K562/A02 tumor xenografts with statistical significance( P

Objective To investigate the influence of hypoxia on leptin expression in serum,CSF and brain tissue of C57BL/6J mice.Methods C57BL/6J mice were divided into 3 groups:the normal control,24-hour hypoxia group and 48-hour hypoxia group.The latter two groups exposed to hypoxia in the man-made auto pressure and hypoxia control cabin(XQ-I).Radioimmunoassay was used to detect the leptin level.Results The leptin level in the serum,CSF and brain tissue of mice exposed to hypoxia were higher than that of normal control,but no difference was found between 24-hour hypoxia group and 48-hour hypoxia group.Conclusion Hypoxia probably induces the increasing of leptin expression in fat tissue,as well as in the central nervous system.
