Objective:To evaluate the positive rate of the bronchodilation test (BDT) in asthmatic children with normal forced expiratory volume in 1 second (FEV 1), forced vital capacity (FVC) and FEV 1/FVC, so as to improve the recognition of the importance of the BDT test in asthmatic children with normal FEV 1, FVC and FEV 1/FVC. Methods:Children aged 5-14 who were diagnosed with asthma in the outpatient clinic of Shandong Provincial Hospital Affiliated to Shandong University from September 2018 to August 2019 and willing to receive pulmonary function and BDT examinations were enrolled.Data of pulmonary function of children with normal FEV 1, FVC and FEV 1/FVC were collected to analyze the rate of positive BDT results and the status of small airway function. Results:A total of 1 631 asthmatic children with normal FEV 1, FVC and FEV 1/FVC were enrolled in this study, including 1 414 children with normal pulmonary function and 217 children with small airway dysfunction.Fifteen minutes after the bronchodilator was inhaled, 127 children (87 males and 40 females) showed positive BDT results, accounting for 7.8%.Among these children, 62 cases (28.6%) with co-existing small airway dysfunction showed positive BDT results.The improvement rate of FEV 1 was 8.0% to 11.9% in 132 cases (8.1%). The FEV 1 before bronchodilator inhalation accounted for (98.5±10.3)% of the predicted value.Fifteen minutes after terbutaline sulfate inhalation, the improvement rate was 13.5% (12.5%, 16.2%). The improvement rates of forced expiratory flow at 50% of FVC exhaled (FEF 50, r=-0.339, P<0.01), forced expiratory flow at 75% of forced vital capacity exhaled (FEF 75, r=-0.400, P<0.01), maximum mid-expiratory flow(MMEF, r=-0.375, P<0.01) were negatively correlated with their baseline values.The improvement rate of FEV 1 was not associated with its baseline value ( r=-0.128, P=0.153), but negatively correlated with the baseline value of MMEF ( r=-0.231, P<0.01). Conclusions:BDT results are positive in some asthmatic children with normal FEV 1, FVC and FEV 1/FVC.It is recommended that BDT testing should be conducted as much as possible in the diagnosis and follow-up of children with typical or atypical asthma.In this way, the diagnosis can be confirmed and the current optimal results can be obtained.Meanwhile, small airway function testing is helpful for comprehensive assessment of asthma and its control level.

OBJECTIVETo provide a new approach for studying the compatibility principle of traditional Chinese medicine formula (TCMF) by constructing compatibility network of phamarcologic action of TCMF according to the network theory.

METHODWith Chinese herb as node and compatibility relationship of herb-herb as edge according to network theory, compatibility network of phamarcologic action of TCMF was constructed after the compatibility relationship of herb-herb was analysed by two-way analysis of variance (ANOVA)through phamarcology experiment. Then compatibility principle of TCMF was analysed with network efficiency (NE) and NE related parameters.

RESULTThe network approach was applied for studying compatibility principle of Jiawei Shengmai San on it's antimyocardial ischemia reperfusion injury action. The results indicated that rhizoma corydalis was the main herb in Jiawei Shengmai San, and in turn was radix ophiopogonois, radix salvia miltiorrhiza, radix ginseng and fructus schizandrae, radix ginseng and radix salvia was clustered first, and in turn was radix, Formule composed of ophiopogonois and fructus schizandrae. Formule composed of radix ginseng and radix salvia, and radix ophiopogonois and fructus schizandrae; radix ginseng, radix salvia miltiorrhiza and rhizoma corydalis was the most effective one among all the formulaes. These results were consistent with validation experiments.

CONCLUSIONStudying compatibility principle of TCMF by network theory is a new and feasible method.

OBJECTIVE: To study the bone conductive hearing loss in adults of otitis media with effusion (OME). METHOD: Fifty adults of OME treated in our hospital, from Mar. 2009 to Feb. 2010, were enrolled for analyzing bone conduction hearing loss (BCHL) before auripuncture and after auripuncture, the difference between which were compared in 51 ears. BCT of pre auripuncture 24 subjects, BCT of post-auripuncture 22 subjects, and BCT recovered from OME 9 subjects compared with the contralateral ear respectively. High and extend high frequency (8, 10, 12, 16 kHz) air conduction threshold (ACT) after recover from OME was compared to the normal contralateral ear in 4 adults. RESULT: BCT improved significantly after auripuncture at the frequencies (0.5-4.0 kHz), and the improvements in 4.0 kHz are more than that in 0.5 kHz significantly (P<0.05). In the unilateral OME subjects, BCT, of post auripuncture and recovered from OME, nearly recovered to the same level as the contralateral ear in most cases. While high and extend-high frequency (8, 10, 12, 16 kHz) ACT elevated in 3 of 4 patients recovered from OME. CONCLUSION Both effusion in middle ear and injury in inner ear could result in the elevation of BCT. Elevation of BCT at regular frequencies (0.5-4.0 kHz) is frequently associated with the effusion in middle ear, while these frequencies were insensitive in the early inner ear injury. The high and extend high frequency ACT elevation may be sensitive for the early sensorineural hearing loss. As the disease prolonged, sensorineural hearing loss of the lower frequencies (0.5-4.0 kHz) could be detected of OME patient.

OBJECTIVE: To evaluate the clinical efficacy of the intratympanic methylprednisolone perfusion for patients of intractable Meniere's disease (MD). METHOD: Ten cases (10 ears), collected from Janu 2008 to Janu 2010, of intractable MD were studied retrospectively. The micro-catheter was placed into the tympanum of the affected ear, then methylprednisolone was imported into the tympanum once a day for 10 days. The average followed-up duration was (15. 4 +/- 5. 4) months after the perfusion. The treatment effect of vertigo, hearing loss and activity capacity was evaluated with Diagnostic Criteria for MD set by the Guiyang Meeting in 2006. The efficacy of tinnitus was analyzed by comparing the score of tinnitus handicap inventory (THI) before and after treatment. RESULT: The vertigo was absolutely controlled in 7 patients (grade A), partially controlled in 2 patients (grade B) and no efficiency in 1 patient (grade C). The 2 patients in grade B had a vertigo again in 9 months and 11 months after intratympanic perfusion, respectively, while the frequency, severity and duration of their vertigo softened obviously. Puretone threshold average (PTA) at the affected frequencies was decreased to within the level of 20 dB in one patient and was improved more than 30 dB in another one (grade A), improved 15 dB to 30 dB in 4 patients (grade B), and improved less than 15 dB in the other 4 patients. The average score of THI was 48.80 +/- 7.25 and 41.9 +/- 7.78 before and after perfusion respectively. The ability capacity of all the 10 patients after treatment was as normal (grade A), i. e. All of them could lead an independent life. There was no irreversible tympanic perforation in the operated ear and there was no other complications left. CONCLUSION Intratympanic methylprednisolone perfusion through the micro-catheter is a safe and effective method for the intractable Meniere's disease.

Objective    To explore the safety and feasibility of spontaneous breathing anesthesia combined with tubeless uniportal thoracoscopy in pulmonary bullae surgery. Methods    Totally 112 patients with pulmonary bullae in the Affiliated Hospital of Inner Mongolia Medical University from March 2015 to May 2017 were enrolled. According to the random number chosen by computer, the patients were randomly divided into two groups: a tubeless group (spontaneous breathing anesthesia combined with tubeless uniportal thoracoscopy) and a control group (uniportal thoracoscopy by general anesthesia with tracheal intubation) . There were 49 males and 7 females with an average age of 25.5±6.5 years in the tubeless group, and 50 males and 6 females with an average age of 23.5±4.5 years in the control group. The difference of the lowest intraoperative arterial oxygen saturation (SaO2), SaO2 at postoperative one hour, operation time, postoperative awakening time, hospital stay, hospitalization cost and postoperative pain score were analyzed. Results    There was no significant difference between the two groups in the operation time, the lowest SaO2, SaO2 at one hour after the operation and the partial pressure of carbon dioxide (PaCO2). The awakening time and duration of postoperative hospital stay in the tubeless group was shorter than those in the control group (P=0.000). The cost of hospitalization in the tubeless group was less than that in the control group (P=0.000). The discomfort caused by urinary tract and visual analogue score (VAS) in the tubeless group were better than those in the control group. Conclusion    It is safe and feasible to use spontaneous breathing anesthesia combined with tubeless uniportal thoracoscopy in pulmonary  bullae resection.
