Objective:To analyze the clinical manifestations and esophageal motility characteristics of patients with gastroesophageal reflux disease (GERD) and extra-esophageal symptoms.Methods:From January 1 to October 30, 2018, at PLA Rocket Force Characteristic Medical Center, 180 hospitalized patients diagnosed with GERD and extra-esophageal symptoms were retrospectively analyzed. The patients were divided into laryngopharyngeal symptom group (65 cases), airway symptom group (58 cases) and mixed symptom group (57 cases). General data, clinical symptoms, gastroscopic manitestations, the results of high-resolution esophageal manometry and 24-hour multichannel intraluminal impedance and pH monitoring of each group were analyzed and compared. Chi-square test and one-way analysis of variance were used for statistical analysis.Results:The patients aged <40, 40 to 60 and >60 years accounted for 12.8% (23/180), 53.3% (96/180) and 33.9% (61/180), respectively, and the difference was statistically significant ( χ2=12.030, P=0.017). There were 18.9%(34/180) of patients without typical reflux symptoms. There were statistically significant differences in the incidence of ectopic esophagogastric mucosa or Barrett esophagus under gastroscopy between laryngopharyngeal symptom group, airway symptom group and mixed symptom group (21.5%, 14/65; 5.2%, 3/58 and 8.8%, 5/57, respectively) ( χ2=8.578, P=0.014). There were no statistically significant differences in the lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure or distal contractile integral between laryngopharyngeal symptom group, airway symptom group and mixed symptom group ((8.57±0.76), (8.87±0.79), and (10.51±0.97) mmHg (1 mmHg=0.133 kPa); (44.75±2.86), (42.81±4.06), and (39.14±3.20) mmHg; (506.13±64.30), (432.59±78.10), and (682.99±82.28) mmHg·s·cm)(all P>0.05). The DeMeester score of laryngopharyngeal symptom group , mixed symptom group and airway symptom group was (14.33±2.09), (21.94±5.30) and (30.47±5.85) points, respectively, and the difference was statistically significant ( F=3.226, P=0.043). The results of multi-channel impedance monitoring showed that acid reflux and weak acid reflux were the main reflux in the patients, which accounted for 55.5% (76/137) and 34.3% (47/137), respectively. Among 87.6% (120/137) of the patients, reflux mainly occurred in the upright position while 12.4% (17/137) of the patients had reflux in the supine position. Conclusions:The extra-esophageal symptoms of GERD is associated with age. Ectopic esophagogastric mucosa or Barrett esophagus are more common in GERD patients with laryngopharyngeal symptoms. There are more acid exposure and pathologic acid reflux in GERD mainly with airway symptoms. Weak acid reflux at upright position plays an important role in the reflux mechanism of GERD with extra-esophageal symptoms.

Objective To explore the influence of the acute cauda equina compression on the lumbosacral spinal cord; To clarify the pathologic change of the motor neuron after acute cauda equina compression. Methods 27 canis familiaris were randomly divided into 9 groups (3 in each) : one for normal group, one for control group, and seven for compression groups. The control group and compressed groups was given operation and the sac made of silica gel was placed under the lamina of L5-6. Water was injected into the sac until their posterior legs paralysis in compressed groups, the animals had been compressed for 4, 8, 12, 24, 48, 72, 168 hours. The control group were not injected water. Cells apoptosis was investigated with the technology of TdT-mediated biotin dUTP nick end-labeling (TUNEL)staining. The Bcl-2 Bax and Caspase-3 protein was investigated by immunohistochemical method. Results TUNEL staining cells in anterior horn presented after compressed 8-12 hours, and at 72 hours the number of positive cells got to maximum, it decreased subsequently after 168 hours. The protein of Bax, Bcl-2 expressed a little in normal motor neuron. The caspase-3 protein didn't express in normal cell. They all reached the peak at 72 hours after compression.Conclusion The apoptosis of motor neuron occurred earlier after cauda equina acute compression. Bax protein restrained Bcl-2 protein then active caspase-3 and conduced apoptosis of motor neuron.

Objective　To study the effect of portal vein blocking on the permeability of the intestinal mucosa in pigs. Methods　Healthy Rongchang pigs were divided into 3 groups: ① sham operation group(SO), ② portal vein clamping for 45 min group (PVC-45'), ③ portal vein clamping for 60 min group (PVC-60'). Urine lactulose/mannitol(L/M) ratio was measured after portal vein blocking. Results　The L/M ratio was increased significantly (P<0.05) in PVC-45' and 60' groups than in SO group, with that of PVC-60' higher than that of PVC-45' group, but not significantly. Conclusion　The increase of intestinal mucosal permeability after portal vein blocking is an early and important index for the damage of the intestinal mucosa barrier.
