Objective To establish a method for the determination of aluminium in drinking water by flow injection analysis instrument.Methods In a hexamine buffer solution(pH=6.0),phenanthroline solution and ascorbic acid as the anti-interference agent,aluminium could react with chromazurol S solution and form a compound,of which maximum absorption was at 550 nm.Results The linear range for this method was 5-200 ?g/L.The correlation coefficient was 0.999 3,the detection limit of this method was 2.0 ?g/L,the recovery rates were in the range of 92.2%-108% and RSD were in the range of 2.5%-8.2%.Conclusion The flow injection method is simple,rapid,accurate and is applicable to the determination of aluminium in drinking water.

AIM To observe the inhibitory effects of tricin on the airway inflammation in low concentration LPS induced asthma mice.METHODS The model of asthma mice with airway inflammation was induced by low concentration LPS plus OVA.There were four groups:blank control group,asthma model group,tricin treatment group and dexamethasone (positive drug) treatment group.The levels of inflammatory factors,including NO,TNF-α and IL-1β,in bronchoalveolar lavage fluid (BALF) were detected by ELISA;the pathology of lung tissue was observed by HE staining;the mRNA and protein expressions of TLR4,MyD88 and NF-κB p65 in alveolar macrophages were detected using real-time quantitative PCR (RT-PCR) and Western blot.RESULTS Tricin could significantly decrease the levels of NO,TNF-α and IL-1β in BALF of asthma mice and improve lung inflammation.It could also down-regulate the relative mRNA and protein expressions of TLR4,MyD88 and NF-κB p65.CONCLUSION Tricin has inhibitory effects on airway inflammation in asthma mice,whose mechanism may be related to the intervention of TLR4/MyD88/NF-κB pathway.

Moxibustion dose, closely related to moxibustion methods and sensations, directly influences the efficacy. Moxibustion dose is affected by quantity factors and patients' sensations. Quantity factors are volume and number of moxa cones, and moxibustion time and frequency, etc. The relationship between moxibustion dose and efficacy is discussed from quantity factors and sensations in the paper.

OBJECTIVE:To provide reference for the application of micro-lecture in pharmacology teaching. METHODS:Based on a correct view of micro-lecture and the sample of positive inotropic effect and mechanism of cardiac glycosides,mi-cro-lecture design of pharmacology was explored from aspects of design objects,contents,technical support and application mode. RESULTS:As the main carrier of micro-lecture,video took the advantages of topic prominence,resource diversity,short and pithy and easy to use;the objects were five-year undergraduate medical students of the Jiangxi Univesity of Traditional Chinese Medicane;and the key and difficult points in pharmacology courses were selected for the complete teaching of these points in a short time as much as possible;record screen-based software model was conduced for video making and the course was uploaded to Kingsoft disk sharing. CONCLUSIONS:As a new teaching mode,course design is the basis and it is essential for the smooth de-velopment. A good micro-lecture design has positive improvement effect on improving the teaching efficacy of Pharmacolgy tradi-tional class.

Early esophageal cancer is derived from mucosa and submucosa without lymph node metastasis. They are detected generally during endoscopy or physical examination without clinical symptoms. Main treatment of early esophageal cancer is endoscopic resection,and the 5-year survival rate is over 90% . Once symptoms occur,local lymph node metastasis is often present and the prognosis is poor with a markedly reduced 5-year survival rate. Thus it is vital to diagnose and treat esophageal cancer at an early stage. With the development of endoscopic techniques,especially the proficiency of endoscopic ultrasonography(EUS),the detection rate of early esophageal cancer has been increased greatly. EUS also plays an important role in the staging of early esophageal cancer. This article reviewed the application of EUS in diagnosis and treatment of early esophageal cancer.

Ventilator associated pneumonia (VAP) is a challenging complication of critical illness.Aerosolized antibiotic is an option for the management of VAP currently,as it is reported that it could increase levels of drug in alveolar without increasing systemic toxicity.The articles that focused on the aerosolized antibiotics in the treatment of VAP and its influence factors were reviewed,and it was found that to achieve maximum drug delivery efficiency and reduce the influence of nebulization method,some factors,such as ventilation modes,tidal volume,nebulizer type,should be adjusted and monitored during the treatment.

BACKGROUND: Research shows that the auditory brainstem response (ABR) wave amplitude of tinnitus patients often act as big Ⅲ small Ⅴ.Tinnitus masking is a therapy of tinnitus, then how dose the ABR change in the process of tinnitus masking?OBJECTIVE: To observe the changing characteristics of ABR in patients with tinnitus as well as the changing rules of ABR after tinnitus masking.DESIGN: Case-control and self-control.SETTING: Department of Otorhinolaryngology, First Hospital of Jilin University.PARTICIPANTS: Continuous tinnitus group: 63 cases (68 ears) were selected from the Clinic of First Hospital of Jilin University from March 1999to October 2001. Control group: 10 cases (20 ears) of normal hearing youth (20-23 years old). All subjects received the examination and treatment voluntarily.METHODS: The ABR was firstly detected in tinnitus patients (foreheadmastoid conducting method was adopted), and examination of tinnitus as well as tinnitus masking test (masking for 5 minutes) were respectively conducted, immediately after that, the ABR was detected to do control-observation with the control group.MAIN OUTCOME MEASURES: ①The characteristics of ABR in patients with tinnitus. ②Effects of tinnitus masking on the amplitude wave of ABR, which was divided into positive group in residual inhibition test and negative group in residual inhibition test for analyzing.RESULTS: A total of 83 subjects were involved in the analysis of results.①The amplitude wave of ABR in youth of normal hearing were small Ⅲ big Ⅴ, whereas that in 22 ears (32.4％) out of 63 subjects (68 ears) were big Ⅲ smallⅤ, in which 17 ears were of patients positive residual inhibition test, and 5 were of negative.②After tinnitus masking therapy, 10 ears out of 17 ears of patients positive in residual inhibition test turned from big Ⅲ small Ⅴ to small Ⅲ big Ⅴ, and the wave amplitude of Ⅲ wasre duced in 3 ears, while the ABR in 2 ears out of 5 ears of negative patients turned to small Ⅲ bigⅤ, and there were no changes in other 3 ears.CONCLUSION: Tinnitus masking therapy can convert the abnormal ABR wave amplitude in patients with tinnitus to normal, which will be taken as the objective index in judging whether it is positive in residual inhibition test.
