Objective: To study the expression of TNF\|α and CD68 in nasal polyps tissue and their significance. Methods. Paraffin sections of 19 nasal polyps and 8 chronic rhinitis samples were studied with immunohistochemical technique. Results. The expression of TNF\|α were stronger in nasal polyps tissues than that in controls. Numerous CD68 positive cells were found in epithelium laryer and in the lamina propria of nasal polyps. There were positive relationship between the expression of TNF\|α and that of CD68(r=0.615). Conclusion. It was suggested that activized macrophage as antigen\|presenting cell in the development of nasal polyps, may play a important role through upregulated TNF\|α′s synthesis and secretion.

Two lipase active fractions Lip1 and Lip2 were purified from the cell extract of Rhizopus chinensis CCTCCM201021.Both gave a single band on SDS-PAGE after using ammonium sulfate precipitation、Phenyl-Sepharose FF、DEAE-Sepharose FF and Sephadex G100 gel filtration chromatographies.The molecular masses of two lipases were 59.2kD and 39.4kD respectively.Lip1 and Lip2 showed optimal pH at 8.0 and 8.5 and their optimal temperatures were 40℃ and 35℃ respectively.The substrate specificity of the two lipases was obviously different.Lip1 was more specific to long chain fatty acid of p-nitrophenyl esters while Lip2 had a preference for the hydrolysis of short chain fatty acid of p-nitrophenyl esters.Lip1 had 1,3-position specificity for triacylglycerols hydrolysis while Lip2 had nonspecific position.Both lipases were stimulated by Ca 2+、Mg 2+ while SDS had strong inhibition on their activities.Lip1 and Lip2 had good stability in cyclohexane、hexane、heptane and isooctane(30% V/V).

Objective To evaluate the value of bronchoscopy specimens' microRNA-21 (miRNA-21) and microRNA-431 (miRNA-431) in the development and prognosis of pulmonary tuberculosis. Methods A total of 43 confirmed pulmonary tuberculosis patients admitted to Shaanxi Provincial Tuberculosis Prevention Hospital from May 2022 to July 2023 were included as the study group, and 43 healthy volunteers during the same period were included as the control group. In the study group, the severity of lung lesions was classified as mild in 14 cases, moderate in 19 cases, and severe in 10 cases. According to the prognosis, patients were divided into poor prognosis and good prognosis groups. The miRNA-21 and miRNA-431 levels of patients with different disease severity and prognosis in the study group and the control group were compared, and the factors affecting the development and prognosis of tuberculosis were analyzed by logistic multivariate analysis, and a prediction model for the development and prognosis of tuberculosis was established. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of the model. Results The levels of miRNA-21 and miRNA-431 in the study group were significantly higher than those in the control group, and the difference between groups was statistically significant (P<0.05). In the study group, the levels of miRNA-21 and miRNA-431 were positively correlated with the severity of the disease, and the levels in severe pulmonary tuberculosis patients were significantly higher than those in mild and moderate pulmonary tuberculosis patients, with statistically significant differences between the groups (P<0.05). In the study group, the levels of miRNA-21 and miRNA-431 in patients with pulmonary tuberculosis with poor prognosis were significantly higher than those in patients with pulmonary tuberculosis with good prognosis, with statistically significant differences between the groups (P<0.05). Using miRNA-21 and miRNA-431 expression as independent variables, and the development and prognosis of pulmonary tuberculosis as dependent variables, logistic regression analysis was performed. The results showed that the high expression of miRNA-21 and miRNA-431 were both influential factors for the development and prognosis of pulmonary tuberculosis (P<0.05). The ROC curve analysis showed that the optimal cutoff value of the prediction model was 0.0895, and the area under the curve (AUC) of miRNA-21, miRNA-431 and combined were 0.614 (0.651-0.732), 0.671 (0.686-0.811), and 0.891 (0.787-0.993). Conclusions The high expression levels of miRNA-21 and miRNA-431 in patients with tuberculosis are closely related to the development of the disease and can predict the prognosis of patients with tuberculosis to a certain extent. The comprehensive application value of combined diagnosis is high, and it is recommended to promote clinical use.

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.
