Objective To investigate the role of acid and bile reflux in children with gastroesophageal reflux disease (GERD) and to evaluate the significance of detecting acid and bile reflux in diagnosing GERD in children.Methods Using ambulatory 24 h pH mo-(nitoring) and bilirubin monitoring technique, we simultaneously assessed the changes of intraesophageal pH and bile reflux in 23 subjects (including 11 healthy controls and 12 patients with GERD).Results The time of esophageal acid exposure (pH

The mesencephalic auditory nuclei,the nuc leus mesencephalicus lateralis,pars dorsalis (MLd) and nucleus intercollicularis (ICo),were investigated in the adult songbird (Lonchura striata) for met -e nkaphalin (ENK) immunoreactivity and neuronal connectivity. It was found that th e ENK labeled fibers and neurons were distributed in the MLd margin and ICo, but were nearly absent in the central MLd. After a neural tracer biotionylated dext ran amine (BDA) was injected into the MLd margin, the labeled fibers and neurons were found in the brain nuclei or areas from telencephalon to medulla. There we re five nuclei or areas project to MLd margin:the cup of n. robustus archistriat alis (RA) of telencephalon, the n. preopticus anterior (POA) of hypothalamus, th e n. parabrachialis ventrolateralis (PBv1) of pons ,the n. rostral ventrolatera l medulla (RVL) and the n.infraolivaris superior (IOS) of medulla. The MLd margi n projected to two diencephalic areas, the shell of n. ovoidalis (Ov shell) and the lateral hypothalamus (LHy). The projections from MLd margin to PBv1 and hypo thalamus suggest that the MLd margin in the songbird may play an important role in the integration of anditory-vocalization, endocrine and other physiological activities.

OBJECTIVETo explore the incidence of acid and bile reflux in children with gastroesophageal reflux disease (GERD) and to study the roles of bile and gastrin in the pathogenesis of childhood GERD.

METHODSForty-two cases of GERD were divided into two groups according to endoscopic findings: reflux esophagitis (RE) and non-erosive reflux disease (NERD). The patients underwent 24-hr ambulatory esophageal pH and bilirubin monitoring. The serum concentration of gastrin was detected by radioimmunoassay. Thirteen children without gastroesophageal reflux symptoms, digestive tract disease and severe systemic organic disease served as the Control group.

RESULTSOf the 42 cases of GERD, 24 cases were confirmed with RE, with esophageal mucosal lesions, and 18 were NERD without esophageal mucosal lesions by endoscopy. Both acid and bile reflux parameters, including the percentage of total time with pH < 4 and bilirubin absorbance >/= 0.14, the total number of reflux episodes and the number of bile reflux episodes lasting longer than 5 minutes, were significantly higher in the GERD patients than those in the Control group (P < 0.05). The time of esophageal acid exposure (pH < 4) and the percentage of total time with bilirubin absorbance >/= 0.14 increased significantly in the RE group compared with in the NERD group (P < 0.05). Sixteen RE patients had a mixed reflux of bile and acid (66.7%) but only 6 NERD patients (33.3%) had (P < 0.01). The serum concentration of gastrin in the RE group (125.12 +/- 45.06 pg/mL) and the NERD group (98.22 +/- 27.92 pg/mL) was significantly higher than that of the Control group (74.22 +/- 20.34 pg/mL) (P < 0.01, P < 0.05 respectively). A significant difference was noted in the serum concentration of gastrin between the RE and the NERD groups (P < 0.05).

CONCLUSIONSMixed reflux of bile and acid are common in children with GERD. Bile reflux may play a role in the development of GERD. Gastrin parasecretion may participate in the development of GERD. Gastrin and bile reflux may have synergistic effects on the development of childhood GERD.

Objective To study the morbidity of cough variant asthma (CVA) among patients with chronic cough syndrome and its relative risk factors. Methods Patients were recruited with detailed history on their illness. Data were collected on physical examination, chest X-ray, eosinophil cell counts, pulmonary ventilation with histamine stimulating test and bronchi dilation test. According to available data, diagnosis of CVA was confirmed and the relative factors Questionnaire form was completed for each patient. Results Among 473 patients with chronic cough, 95 (44 male and 51 female) were confirmed to be CVA (20.08%). Analysis of the relative factors suggested that CVA was associated with multiple factors. Morbidity of CVA was associated with season, personal histories on allergy and family history on asthma, CVA could be induced by upper respiratory tract infection, inhale of oil vapor, acrimony air, over-burdened physical exercises etc. Conclusion For patients with chronic cough symptom, clear diagnosis of CVA, avoid of passable risk factors and timely medical intervention when necessary, would be helpful in controlling clinical courses and improving the prognosis of the disease.

·AIM: To investigate the clinical efficacy of intravitreal injection of Ranibizumab and 577nm laser in the treatment of retinal vein occlusion combined with macular edema.·METHODS: Totally 64 patients ( 64 eyes ) with retinal vein occlusion accompanied by macular edema were treated in our hospital from June 2014 to March 2017. Among them, 40 cases ( 40 eyes ) were in the central retinal vein occlusion group, 24 cases (24 eyes) were in the branch retinal vein occlusion group. They were treated with intravitreal injection of ranibizumab 0. 5mg, and the laser photocoagulation of 577nm was performed at 5 to 7d after injection. Meanwhile, 42 patients who did not wish to be treated with injection were treated with laser treatment only. The changes of the indexes before and after treatment were compared.·RESULTS: The average number of blocking group repeated injection of branch retinal vein for 1. 71 ± 0. 79, while the average number of patients with repeated injection of central retinal vein occlusion was 2. 11 ± 0. 80. All patients requiring repeated injections interval was greater than 30d. At 1mo after treatment, there was no patients with decreased visual acuity in branch retinal vein occlusion group, while there were 6 eyes with that in central retinal vein occlusion group, 14 eyes in simply laser group. The mean best corrected visual acuity (LogMAR) of the three groups was 0. 87±0. 60, 0. 57±0. 48 and 0. 54±0. 32, respectively, were significantly lower than that before treatment (1.26±0.53, 0.86±0.39, 0.76±0.26;P< 0. 05 ). The mean macular retinal thickness before treatment was 683.24±211.83, 557.39±128.29 and 545.82± 129. 76μm, were significantly higher than those at the last follow-up 412. 09±257. 38, 356. 29 ± 133. 02 and 322. 78 ± 109. 55μm ( P < 0. 05 ). There were 6 cases of subconjunctival hemorrhage in patients treated with laser therapy combined with laser therapy. The intraocular pressure increased to 25mmHg in 2 eyes in 2 patients and recovered after symptomatic treatment.· CONCLUSION: Intravitreal injection of ranibizumab combined with 577nm laser treatment can greatly enhance the visual acuity, effective decrease macular retinal thickness in patients with retinal vein occlusion and macular edema.

Objective To estimate correlation between phonetically balanced maximum(PB max)and pure tone auditory threshold in auditory neuropathy(AN)patients.nethods 0ne hundred and six ANpatients were identified using multipie criteria including PB max,a metric for speech recognition,pure tone auditory threshold.acoustic emission test.distortion products otoacoustic emission(DPOAE) and auditory brainstem response(ABR).SPSS statistical software was used to estimate the Pearson's correlation between PB max and pure tone auditory threshold and to test whether pure tone auditory threshold,or auditory configuration had a significant impact on PB max.Results Even the patients had the same or similar values for pure tone auditory threshold or auditory configuration.varied values of PB max were found in two hundreds and twelve ears for 106 patients.Analysis of the data for 106 patients revealed a negative correlation(r=-0.602,P<0.01) between PB max and pure tone auditory threshold,i.e.hearing loss at a mild relates to a lower PB max.By using analysis of variance(ANOVA)method,it Was found that both pure tone auditory threshold and auditory configuration had a significant(P<0.01)impact on the patients' PB max.Conclusions This analysis implicated the promise and potential of pure tone auditory threshold and auditory configuration for predicting PB max of the AN patients,and improving the diagnosis of AN.
