Background The rat model of N-methyl-N-nitrosourea (MNU)-induced photoreceptor cell apoptosis is often used to study retinal degeneration.But the changes in the gene expression patterm in retinal degeneration in rats have not been reported.Objective This study was undertaken to investigate regulation of gene expression in the retina of MNU-induced retinal degeneration in rats by performing microarray analysis of retinal RNA.Methods Fifty 6-week-old SD rats were numbered and randomized into the normal group and the model group.The retinal degeneration model was established by a single hypodermic injection of 40 mg/kg of MNU,and the rats in the normal group received equivalent volume of physiological saline in the same way.The rats were sacrificed 12 hours or 24 hours after injection.Retinal sections from the right eyes were prepared for the measurement of the retinal thickness by histopathological examination,and retinas from the left eyes were used to confirm the differential gene expression as detected by microarray (normal group and 12 hours model group).Genes exhibiting changes in expression by ≥2.0 folds were further confirmed using real-time PCR.Results The whole thickness of the retina declined in the rats from the 24 hours model group compared to the normal group and 12 hours model group (t =9.926,P=0.002;t=2.736,P=0.028).The thickness of the outer nuclear layer was (26.58±2.90) μm in the 24 hours model group,showing a significant decrease in comparison with (38.11 ± 1.01) μm in the normal group and (35.07t3.03) μm in the 12 hours model group (t=6.028,P=0.009;t=6.839,P=0.006).However,there was no significant difference in retinal thickness between the normal group and the 12 hours model group (whole thickness:t=1.541,P=0.324;outer nuclear layer thickness:t=2.040,P=0.134).Microarray analysis of the rat genes showed that out of 17 000 genes,142 genes involved in biological process and 94 genes involved in molecular functions were differentially expressed,where most of them participate in the mitogen activated protein kinase signaling pathway,Tolllike receptor signaling pathway and apoptosis pathway.Real-time PCR analysis demonstrated that the expression of CCL2,IL-1b,CCL3,c-fos,c-myc,p53 and MMP3 were consistently up-regulated,conforming with the results from microarray analysis.Conclusions The changes in gene expression pattern appear in the early stage of MNUinduced retinal degeneration.These microarray results provided clues to understanding the molecular pathways underlying photoreceptor degeneration and indicating the directions for future studies.

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.

Purpose To compare the therapeutic effects of CO2 laser resection and traditional split laryngeal surgery on the early laryn-geal cancer, and to examine relationship between the expression of p27 and PTEN and clinical prognosis in early laryngeal squamous cell carcinoma. Methods 85 patients who underwent CO2 laser resection surgery and 46 patients who underwent split laryngeal surger-y were selected and the occurrence rates after surgery were observed. SP immunohistochemical method was uesd to detect the expression of p27 and PTEN in tumor resection marginal and their surgical margine tissues. Clinical data were collected and all patients were fol-lowed up. Results In the more than two-year follow-up study, 14 of 85 patients in CO2 laser treatment group ( recurrent group) pres-ented with local recurrence and the recurrence rate was 16. 5%, while 6 of 46 patients in split laryngeal surgery group presented with local recurrence and the recurrent rate was 13. 0%. There was no statistical significance in recurrence rate between the two groups ( P> 0. 05). 10 of all the none recurrent patients did not follow the doctor’s advice to quit smoking after the operation, while 12 in the recurrent patients did not, the difference between the two groups was statistically significant (P<0. 01). The positive rate of p27 and PTEN in laryngeal carcinoma tissues and the cancer adjacent tissues ( negative surgical margin tissues ) was 43. 5% ( 57/131 ) , 80. 2% (105/131) and 48. 9% (64/131), 83. 2% (109/131), respectively, with a significant difference (P<0. 01). The positive rate of p27 and PTEN in laryngeal carcinoma tissues of the recurrent group and non recurrent group was 20. 0% (4/20), 47. 7% (53/111) and 10. 0% (2/20), 55. 9% (62/111), respectively, with a significant difference (P<0. 05). While the positive rate of p27 and PTEN in tumor resection marginal tissues of the recurrence group and non recurrence group was 50. 0% ( 10/20 ) , 85. 6% ( 95/111) and 40. 0% (8/20), 91. 0% (101/111), the difference was also statistically significant (P<0. 01). Conclusions There was no statistically significant difference in tumor recurrence rate between CO2 laser surgery and traditional split laryngeal surgery. Postoper-ative recurrence is closely related to resume smoking. The recurrence rate of p27 and/or PTEN negative patients was higher than that of the opposite ones which should be followed up closely after treatment.

Objective To investigate the changes of hematoma and perihematomal edema in spontaneous hypertensive rats (SHRs),as well as the correlation between blood pressures and perihematomal edemaMethods A total of 24 6-month-old male SHRs were included.They were randomly divided into intracerebral hemorrhage 1-,3-,5-,and 7-day groups (n =6 in each group).Blood pressure was determined by tail-cuff sphygmomanometry.Collagenase Ⅳ was injected into caudate nucleus in order to induce a model of intracerebral hemorrhage.Magnetic resonance T2 weighted imaging was used to observe hematoma and perihematomal edema.Results On day 1 after modeling,the blood pressure was decreased significantly compared to that before modeling,and it was elevated gradually on day 3.Parallel profile test showed that the overall profile was parallel between the change rate of blood pressure and the change rate of perihematomal edema volume (F =2.820,P =0.063).The coincident profile test showed that both the overall profiles did not coincide (F =10.961,P =0.000).The change rate of systolic blood pressure was significantly positively correlated with the change rate of perihematomal edema volume (r =0.527,P =0.024) and the change rate of perihematomal edema volume (r =0.755,P =0.000) showed a significant positive correlation.Conclusions Brain edema appeared and expanded rapidly on the day of intracerebral hemorrhage in SHRs.It reached the peak on day 3,and then dissipated gradually.The blood pressure decreased significantly on day 1 after intracerebral hemorrhage,and it began to increase from day 3 till day 7.The changing trends of the blood pressure and perihematomal edema volume were parallel to each other,and the change rate of systolic blood pressure and the change rate of perihematomal edema volume showed a positive correlation.
