ABSTRACT
Objective:To explore the effect of group cognitive behavior therapy (GCBT) on anxiety, depression and quality of life in patients with chronic obstructive pulmonary disease (COPD) in community.Methods:From August to November 2019, patients with moderate COPD in 18 communities in Xuzhou City were randomly divided into the intervention group ( n=240) and the control group ( n=223). The control group received routine management and the intervention group received group cognitive behavioral therapy intervention for 8 weeks on the basis of routine management.Before and after the intervention, FEV 1% predicted value and FEV 1/FVC were measured by pulmonary function tester.Hospital Anxiety and Depression Scale (HADS) was used to evaluate the anxiety and depression of patients.St.George's respiratory questionnaire (SGRQ), COPD assessment test (CAT) and modified medical research council dyspnea (mMRC) were used to evaluate the quality of life of patients.SPSS 20.0 software was used for analysis.The χ 2 test, independent sample t-test, paired sample t-test were used for statistical analysis. Results:After 8 weeks of intervention, the anxiety and depression scores of the intervention group were lower than those of the control group (anxiety: (8.23±4.02) vs (10.71±3.60); depression: (7.87±3.73) vs (10.20±3.72)( t=6.415, 6.185, both P<0.01). After the intervention, there was no significant difference in FEV 1%((51.7±12.3)% vs (52.0±12.6)%) predicted value and FEV 1/FVC((57.3±10.8)% vs (56.9±10.7)%) between the two groups( t=-0.259, 0.400, both P>0.05). The scores of CAT, mMRC and SGRQ in the intervention group were lower than those in the control group((17.35±5.78) vs (20.90±8.00), (1.55±0.82) vs (2.30±1.21), (41.78±21.56) vs (57.08±24.46))( t=-5.061, -7.227, -6.580, all P<0.01). Conclusion:Group cognitive behavioral therapy can relieve the anxiety and depression and improve the quality of life of patients with COPD.
ABSTRACT
To explore the application value of pushing endoscopic submucosal dissection (PESD) in treatment of large area of early cardiac cancer or precancerous lesions. Form January 2017 to January 2020, patients diagnosed as having early cardiac cancer or high-grade intraepithelial neoplasia with largest lesion diameter greater than 2.0 cm at the Baoding NO.1 Central Hospital were enrolled in the study. Patients who received PESD with water-injected knife were included in the PESD group (26 cases), and compared with those who received conventional ESD with common mucosal incision (the conventional ESD group, 17 cases) at the same period. The procedure time, the complete resection rate of lesions and the incidence of complications were analyzed.There were no difference in lesion size between the two groups ( P>0.05). The procedure time of PESD group was 53.7±18.2 min, which was 91.5±26.5 min in the conventional ESD group, and the difference was statistically significant ( P<0.001). In the PESD group, 7 cases (26.9%) had intraoperative hemorrhage. In the conventional ESD group, 8 cases (47.1%) had intraoperative bleeding, and 2 (11.8%) had intraoperative perforation. There were significant differences in the incidence of hemorrhage and perforation between the two groups (all P<0.001). Compared with conventional ESD, PESD can effectively improve the dissection speed, reduce the incidence of complications, and make endoscopic surgery safer and faster.
ABSTRACT
Oral immunosuppression caused by smoking creates a microenvironment to promote the occurrence and development of oral mucosa precancerous lesions. This study aimed to investigate the role of metabolism and macrophage polarization in cigarette-promoting oral leukoplakia. The effects of cigarette smoke extract (CSE) on macrophage polarization and metabolism were studied in vivo and in vitro. The polarity of macrophages was detected by flow cytometric analysis and qPCR. Liquid chromatography-mass spectrometry (LC-MS) was used to perform a metabolomic analysis of Raw cells stimulated with CSE. Immunofluorescence and flow cytometry were used to detect the polarity of macrophages in the condition of glutamine abundance and deficiency. Cell Counting Kit-8 (CCK-8), wound-healing assay, and Annexin V-FITC (fluorescein isothiocyanate)/PI (propidium iodide) double-staining flow cytometry were applied to detect the growth and transferability and apoptosis of Leuk-1 cells in the supernatant of Raw cells which were stimulated with CSE, glutamine abundance and deficiency. Hyperkeratosis and dysplasia of the epithelium were evident in smoking mice. M2 macrophages increased under CSE stimulation in vivo and in vitro. In total, 162 types of metabolites were detected in the CSE group. The metabolites of nicotine, glutamate, arachidic acid, and arginine changed significantly. The significant enrichment pathways were also selected, including nicotine addiction, glutamine and glutamate metabolism, and arginine biosynthesis. The results also showed that the supernatant of Raw cells stimulated by CSE could induce excessive proliferation of Leuk-1 and inhibit apoptosis. Glutamine abundance can facilitate this process. Cigarette smoke promotes oral leukoplakia via regulating glutamine metabolism and macrophage M2 polarization.

ABSTRACT
To evaluate five methods in the estimation on the rate of case fatality during the epidemics of diseases based on the summarizing data. Case fatality rates,derived from the simulation data,2003 SARS epidemic data in Hong Kong,Singapore Beijing and the 2013 H7N9 epidemic data in mainland China were analyzed,using these 5 methods. Results from the simulation analysis discovered that the relative errors and the standard deviations of the Chen[7,8] (method 3),Chen[9] (method 4) were minor with high accuracy. Data from the analysis on 2003 SARS epidemic was noticed that the estimation from method 3,4 in Hong Kong and Singapore both showing high veracities. Since the case fatality rate reported in Beijing was not a constant value,method 5 showed low accuracy even though it was close to the final case fatality rate. Data from the 2013 H7N9 epidemic showed that the estimations of method 1,2,3,4 were all higher than that in the method 5, suggesting that method 3,4 could be used to estimate the case fatality rates of epidemics more precisely.

ABSTRACT
We analyzed the microbial diversity and quantity of nitrifying bacteria in the enrichment reactor by Terminal Restriction Fragment Length Polymorphism (T_RFLP), a cultured-independent molecular technique. The result indicated that nitrobacteria enriched the best, and the diversity index decreased 62.80% compared with the initial data. Nitrobacteria were predominant in the reactor. Meanwhile, we studied the microbial diversity before and after adding Nitrobacteria into shrimp ponds, and analyzed several major bacterial species that existed stably in the pond. According to the analysis by T_RFLP program, species including Brevibacillus brevis, Microbacterium lactium, Azoarcus indigens and Bordetella holmesii were the dominant bacteria in the ponds.
