Objective To test the reliability and validity of ICF Core Sets for Chinese COPD patients.Methods Fifty-two COPD patients were measured with ICF Core Sets for COPD patients and SF-36. For reliability test, the internal consistency was analyzed and expressed by Cronbach α coefficients and split-half reliability. For va-lidity test, the content validity and criterion validity were analyzed and expressed with Spearman rank correlation coef-ficients. Results For body function, body structure and activity and participation, there were good internal consis-tency (Cronbach α coefficients 0. 698～0.957). For environmental factors Crnnbach α coefficient and split-half reli-ability did not exist. Most items of body function, activity and participation and body structure possessed good content validity. There was concurrent validity for ICF components of body function, body structure and activity and participa-tion with SF-36, FEV1/FVC, COPD grade and health self-assessment. The environmental factors demonstrated poor reliability and validity. Conclusion The ICF Core Sets for COPD patients showed good reliability and validity. It is a good comprehensive functional measurement scale for COPD patients, but it is necessary to test the generality of this result, and some items need to be adjusted.

Objective To evaluate early diagnosis by gastroscopy for the causes of gastroduodenal perforation after successful non-surgical treatment.Method Gastroduodenal perforation patients suspected of benign ulcer in origin on hospital admission undergoing successful non-surgical treatment were examined by gastroscopy within days after the closure.Results Among 284 patients undergoing gastroscopy,277 cases (97.5％) were diagnosed as gastroduodenal ulcer,3 cases (1.1％) as gastric carcinoma,1 case (0.4％) of duodenal diverticulum.There were not major complications developing after gastroscopy.Conclusion Early gastroscopy performed after closure by non-surgical treatment in gastroduodenal perforation patients is safe,helping make definite diagnosis for the cause of perforation.

To compare the difference in tumor immunity and autoimmunity elicited by adenovirus (Ad) encoding human or murine tyrosinase-related protein 2 (AdhTRP2 or AdmTRP2), and to find the most effective way to induce immunity by AdhTRP2 or AdmTRP2, C57BL/6 mice were immunized with AdhTRP2 or AdmTRP2 intramuscularly at different doses of 10(5), 10(6), 10(7) and 10(8) separately (10 mice for each dose). Two weeks after the immunization, in vivo CTL assay and intracellular staining (ICS) of IFN-gamma were carried out to analyze the dose-effect relationship. Tumor growth and vitiligo (as an sign of autoimmunity) were observed until 3 months after challenge with 10(5) B16F10 tumor cells. The results showed that Ad encoding AdmTrp2 induced weak tumor immune response. Similar immunization with AdhTrp-2 elicited stronger protective immunity. CTL activity and IFN-gamma-produced CD8+T cells were directly proportional to dose of AdhTrp2 or AdmTrp2. Moreover, AdhTrp2 group showed tumor rejection in 100% of challenged mice till the end of 3rd month while 60% of mice immunized with AdmTrp2 were protected against tumor. In the whole process of this experiment, no vitiligo was observed in mice immunized either with AdhTrp2 or AdmTrp2. It is concluded that anti-melanoma responses induced by genetic vaccination expressing xenoantigens breaks immune tolerance effectively and is able to elicit strong antigen-specific cytotoxic T cell response without vitiligo.

Objective To observe the MRI imaging manifestations of the ligaments and soft tissues around the atlanto-axial joint in children with atlanto-axial rotation instability.Methods Assigned into observation group were 50 children with atlantoaxial rotatory displacement who had been treated in our hospital from January 2013 to March 2014.Another 50 healthy children were chosen as a control group who underwent health check-ups during the same period in our hospital.Both groups received MRI examinations of the ligaments and soft tissues around the atlantoaxial joint using the same equipment and methods.MRI manifestations and characteristics of the ligaments and soft tissues around the atlantoaxial joint were analyzed and compared between the 2 groups.Results In the observation group,odontoid gap asymmetry appeared on both sides,with left shift in 32 cases and right shift in 18 cases.The MRI imaging PDWI sequence showed a significant better diagnostic sensitivity than the other sequences (T1WI,T2WI and SPAIR) (P ＜ 0.05).The MRI examinations on all the children with different sequences found 50 cases of degree Ⅰ lesion in the observation group and 4 cases of degree Ⅰ lesion in the control group,and 12 cases of degree Ⅱ lesion in the observation group and none degree Ⅱ lesion in the control group,showing a significant difference between the 2 groups regarding the diagnostic sensitivity of lesions of degrees Ⅰ and Ⅱ (P ＜ 0.05).Conclusions MRI can clearly show the rotation displacement of atlanto-axial joint associated with transverse ligament,alar ligament and lesions of the surrounding soft tissues.MRI has a dcfinite diagnostic value for atlanto-axial rotation displacements in children,especially those caused by transverse ligament tear after trauma.

Objective To research early pathological morphology and clinical significance of perforated duodenal ulcer (PDU) closed after non-surgical treatment. Methods Observed morphological changes of duodenal ulcer (DU) lesion with gastroscopy for 302 patients of PDU with non-surgical treatment in early period,when the perforation closed and measured up the clinical indicators during this hospitalization.Results There were 255 patients to be diagnosed with DU caused the perforation. These lesions were characteristic and shown the PDU closed at the bottom and the deep concave ulcers, except for 1 case which complicated by duodenal fistula. These ulcer types were diverse according to the time difference after treatment. No case of re-perforated ulcers or recurrence of peritonitis caused by gastroscopy. Conclusions Deep concave ulcer with A1 phase mainly is an early pathological manifestations of the DU after treated the PDU with non-surgical method characteristically. The wall of the closure of the serosal side is an original form closed perforated ulcer by non-surgical treatment. The risk of perforation associated with the following factors:( 1 )A single DU is located in the anterior wall region. (2)The shape of two kissing DU. (3)The diameter of DU ≥ 1.1 cm. In this case,early diagnosis by using endoscopy is a safe way.

In order to investigate the immunity of unloaded dendritic cells (DCs) derived from murine bone marrow to preexisting lung melanoma metastases of mice, MO5 were intravenously injected to induce lung metastases in syngeneic C57BL/6 mice. Unloaded GM-CSF DCs, PBS and DCs+SIINFEKEL were subcutaneously injected into the mice, which were divided as experimental group, negative control group and positive control group respectively. Monoclonal antibody was used to deplete NK or T cells separately. The immunity-inhibitory effects on the lung melanoma were observed and the corresponding effector cells were examined. It was found that in the experimental and positive groups, the regression was induced in metastatic nodules in the lungs of tumor-bearing mice,but abrogated by treatment with anti-asialo-GM1 but not anti-CD8. It was concluded that the unloaded DCs could suppress the lung melanoma metastases to some extent, which was mediated by NK cells, and could be used as a potent therapeutic agents for lung tumor.

Objective To investigate the iodine nutritional status of pregnant women in Jinan City,which may provide a basis for scientific supplementation of iodine.Methods Ten counties (districts) in Jinan City were divided into five areas as east,west,south,north and middle in 2018.At least one township (street) was selected from each area,and 20 pregnant women were selected from each township (street).Personal information was collected through standardized questionnaires,and household salt samples and urine samples of pregnant women were collected.Salt iodine and urinary iodine were detected by the "General Test Method in Salt IndustryDetermination of Iodine" (GB/T 13025.7-2012) and "Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry" (WS/T 107-2006),respectively.Results A total of 1 169 pregnant women's household salt samples were collected,the median of salt iodine was 22.6 mg/kg.The coverage rate of iodized salt was 90.5％ (1 058/1 169),the qualified rate of iodized salt was 75.8％ (802/1 058),and the consumption rate of qualified iodized salt was 68.6％ (802/1 169).A total of 1 169 urine samples of pregnant women were tested,the median of urinary iodine was 141.9 μg/L,indicating the urinary iodine of pregnant women was insufficient (＜ 150 μg/L).Conclusions The iodine nutrition of pregnant women is slightly inadequate in Jinan City.It is necessary to strengthen the measures in prevention and control of iodine deficiency,and promote the health education measures in pregnant women to improve their iodine deficiency status.

Objective To evaluate the efficacy of Budesonide/formoterol to control asthma under real-life conditions.Methods A muhi-center, open label, non-interventional study was conducted.Asthma control after 12 week therapy with Budesonide/formoterol was assessed by Asthma Control Questionnaire (ACQ) and modified Asthma Control Questionnaire (ACQ5).Results A total of 360 asthma patients were recruited,including 228 adult patients and 132 child patients.After 12 weeks' therapy,all the patients' medium value of ACQ was decreased significantly from 2.03 (adults 2.20, children 1.74) at baseline to 0.60 (adults 0.78, children 0.29) (P < 0.0001), and the medium value of ACQ5 was also decreased significantly from 2.4 (adults 2.24, children 1.76) at baseline to 0.47 (adults 0.62, children 0.20) (P < 0.0001).Conclusion Budesonide/formoterol is effective in asthma treatment, by which most asthma patients obtain and maintain clineal control.

Objective    To analyze the expression of cold-induced RNA-binding protein (CIRBP) in lung adenocarcinoma and its clinical significance based on bioinformatics, in order to provide a new direction for the study of therapeutic targets for lung adenocarcinoma. Methods    The CIRBP gene expression data and patient clinical information data in lung adenocarcinoma tissues and adjacent tissues were downloaded from The Cancer Genome Atlas and Gene Expression Omnibus databases. The expression of CIRBP in lung adenocarcinoma was analyzed. Furthermore, its relationship with clinicopathological features and prognosis in patients with lung adenocarcinoma was analyzed. GO and KEGG enrichment analysis were carried out for the screened genes. The CIRBP protein interaction network was constructed by STRING, and the correlation analysis was carried out using the GEPIA online website. Results    The expression level of CIRBP gene in lung adenocarcinoma tissues was significantly lower than that in adjacent tissues (P<0.01), and its expression level was correlated with T stage and N stage in clinicopathological features. The prognosis of patients with high CIRBP expression in lung adenocarcinoma was significantly better than that with low CIRBP expression. Univariate and multivariate Cox regression analysis showed that CIRBP was an independent prognostic factor in patients with lung adenocarcinoma. GO functional annotation showed its enrichment in organelle fission, nuclear fission, chromosome separation, and DNA replication, etc. KEGG analysis showed that it was mainly involved in cell cycle and DNA replication. Protein interaction network and GEPIA online analysis showed that the expression level of CIRBP  was negatively correlated with the expression level of cyclin B2. Conclusion    CIRBP gene is down-regulated in lung adenocarcinoma tissues, and its expression level is closely related to patient prognosis. CIRBP gene may be a potential therapeutic target and prognostic marker for lung adenocarcinoma.
