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 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.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.

Objective To observe the effect of rosuvastatin calcium on lipid,vascular endothelial growth factor (VEGF),nitric oxide (NO),tumor necrosis factor (TNF)-α and interleukin (IL)-1 in hyperlipidemia patients.Methods One hundred and twenty-seven hyperlipidemia patients were randomly divided into two groups.Patients in the study group included 72 patients which were given rosuvastatin calcium 10 mg and enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The control group included 55 patients which were only given enteric-coated aspirin 100 mg,orally,once a day for 8 weeks.The change of lipid,VEGF,NO,TNF-α and IL-1 was observed before and after treatment.Results Before treatment,the level of total cholesterol(TC),triglyceride (TG),low density lipoprotein-cholesterol (LDL-C),high density lipoprotein-cholesterol (HDL-C),VEGF,NO,TNF-α and IL-1 in two groups had no significant difference (P ＞ 0.05).After treatment,the level of TC,TG,LDL-C,TNF-α and IL-1 in study group were significantly lower than those in control group [(4.410 ± 0.688) mmol/L vs.(6.491 ± 0.744) mmol/L,(1.762 ± 0.834) mmol/L vs.(2.632 ± 0.792) mmol/L,(2.256 ± 0.347) mmol/L vs.(4.544 ± 0.493) mmol/L,(41.14 ± 5.41) ng/L vs.(71.34 ± 6.76) ng/L,(0.22 ± 0.18) μ g/L vs.(0.42 ± 0.23) μ g/L] (P ＜ 0.05).The level of HDL-C,VEGF and NO in study group were significantly higer than those in control group [(1.807 ± 0.730) mmol/L vs.(1.432 ± 0.514) mmol/L,(564.86 ± 120.02) ng/L vs.(451.23 ± 100.72) ng/L,(42.39 ± 6.71) μ mol/L vs.(33.65 ± 6.24) μ mol/L](P＜ 0.05).No adverse reaction occurred in two groups.Conclusions Rosuvastatin calcium can obviously decrease the level of lipid,elevate the expression of VEGF and NO,and reduce the expression of TNF-α and IL-1.Rosuvastatin calcium can improve vascular endothelial function obviously in hyperlipidemia patients.

Objective To investigate the clinical value of 64-slice computed tomography with MinIP and MPR for imaging the bronchus related to a solitary pulmonary lesion (SPL). Methods Seventy-five subjects with solitary pulmonary lesions underwent chest 64-slice CT and their bronchi were analyzed retrospectively. All images of thin-section (0.625 mm) were reconstructed with MPR and MinIP into images of 1, 2, 3, and 5 mm thickness and 1 mm gap in two orthogonal planes along the long axis of bronchus related to the SPL. The image quality of four series of MinIP and MPR images was evaluated in the aspect of bronchus visibility and pulmonary vascular masking. One-way ANOVA with Bonferroni correction and interclass correlation coefficient were used in the statistical analysis. Results (1) The mean scores of display of the bronchi on MinIP images of four series (4.85, 4.77 and 4.84, 4.63 and 4.67, 4.25 and 4.28, in 1, 2, 3, and 5 mm thickness, respectively) and on MPR images of 1 or 2 mm thickness (4.77 and 4.76, 4.04 and 4.27, in 1 and 2 mm thickness, respectively) were good or excellent. MPR images of 1 mm thickness and MinIP images of 1-3 mm thickness showed no significant differences (t=0.318, P> 0.05 for all), but they were superior to MinIP images of 5 mm thickness (t=6.318 and 6.610, P＜0.01). MPR images of 2 mm thickness were inferior to MinIP images of 1-3 mm thickness (t=5.003-8.958, P＜0.01), but there was no significant difference between MPR images of 2 mm thickness and MinIP images of 5 mm thickness (t=1.794 and 0.3181, all P> 0.05). (2) The effect of suppression of pulmonary vascular markings on MinIP images was better with the increase of slice thickness (F=45.312 and 40.415, P＜0.01). The mean scores of MinIP images of 3 mm and 5 mm thickness (4.67 and 4.64, 5.00 and 4.97, for 3 and 5 mm thickness, respectively) were good or excellent, but MinIP images of 2 mm thickness were just acceptable. Conclusion MinIP images of 3 mm thickness may display the bronchus related to SPL more clearly.
