Objective:To examine the utilization and cost of outpatient care and their influencing fac-tors among middle and aged peasant-workers in China. Methods:The data of China Health and Retire-ment Longitudinal Study ( CHARLS) collected in 2011-2012 were used and the data on peasant-workers aged 45 years and older were analyzed with Two-part Model. Results: The four-week outpatient rate of middle and aged peasant-workers was 13. 7% (407/2 974). The determinants of the rate included gen-der, marital status, economic level, household size, the place of insurance enrollment, self-assessed health and having or having no chronic diseases. The average outpatient cost was (400. 3 ± 56. 7) yuan (RMB) and the median was 138. 0 yuan. Multivariate analyses showed that outpatient costs were higher for those males who lived in Eastern China and worked at the same place with insurance enrollment, with fair to bad self-assessed health and chronic diseases. Conclusion:Allowing higher flexibility for migrants to transfer the new rural cooperative medical system ( NCMS ) between rural and urban areas and thus making reimbursement for medical services provided by undesignated providers received immediately could increase the use of outpatient services.

AIM:To investigate the construction of oligonucleotide microarray specialized for pancreatic adenocarcinoma-associated genes and its preliminary application of detecting differential expressed genes in pancreatic cancer.METHODS:Pancreatic cancer related genes were purposely selected,and oligonucleotide microarray was prepared by spotting oligonucleotide probes on glass slides coated with APS-PDC.Labeled cDNA targets for hybridizations were synthesized by reverse transcription from total RNA in the presence of Cy5-dCTP and Cy3-dCTP,respectively.Hybridized microarray was scanned by Agilent laser scanner,and the aquired image was analyzed by Imagene3.0 software.The intensity ratios of Cy3 and Cy5 were calculated.To confirm the expression profiles of these genes,quantitative reverse transcription-PCR (QRT-PCR) was carried out for CDC25B and TUSC3 genes,and β-actin gene was taken as internal control.The product of PCR was quantitated by comparative Ct method.RESULTS:The signal of microarray hybridization was clear,and the images had a lower background and higher signal-noise ratio.In comparison with normal pancreas,twenty -four differentially expressed genes were identified which included seventeen up-regulated and seven down-regulated genes.The results of QRT-PCR demonstrated that the expressions of CDC25B and TUSC3 in pancreatic cancer were up-regulated and down-regulated respectively,which is consistent with microarray results.CONCLUSION:The oligonucleotide microarray specialized for pancreatic cancer is desirable for its specialty and sensitivity,which can simultaneously and parallelly detect multiple pancreatic cancer-associated genes.

Objective To investigate and determine the dietary intake level and food source of elements in Kashin-Beck disease(KBD) and non-endemic KBD areas in parts of Aba Autonomous Prefecture , Sichuan Province. Methods Three KBD villages were selected from each county including the counties of Songpan , Jiuzhaigou and Ruoergai in Aba Autonomous Prefecture with multi stage random sampling method in 2010 , and 122 KBD patients who were diagnosed at county-level or higher-level hospitals were selected from villages. One non-KBD village was selected randomly from each county and 43 controls without KBD or other bone and joint disease were selected in proportion to the number of investigated KBD patients. Dietary intake of each object was recorded 24 hours before the survey using a 24 hour dietary survey method and intake of each kind of food(cooked food) was recorded. Three day dietary intake of each surveyed object was recorded in continuous and the average value was calculated. The local resident representative food samples were collected and 20 kinds of elements in these samples were determined with inductively coupled plasma mass spectrometry ( ICP-MS ) and inductively coupled plasma atomic emission spectrometry(ICP-AES), and daily elements intake was calculated and compared with the relevant intake standards. Results Daily intakes of vegetables and meat were 126.72, 28.25 g, respectively, in patients with KBD. More than 3 times of brick tea was drank by KBD patients than non-KBD people (P<0.05). Per capita daily intakes of Ca, Fe, Mg, K, Na, Zn, I, Cu and Co were less than recommended nutrient intake or allowable daily intake in both groups. More than 80% patients with KBD overtook more Al and Pb than tolerable upper intake levels. Conclusion There is a single dietary structure and a serious shortage of a variety of essential elements intake in parts of Aba Autonomous Prefecture, and the dietary intake level of elements is different between two groups.

OBJECTIVE: To explore the role of the innate immune factors TLR2 and TLR4 in the pathogenesis of chronic rhinosinusitis (CRS) by detecting their expression in different clinical types of CRS and the normal control group. METHOD: Immunohistochemistry was used to detect the expression of TLR2 and TLR4 respectively in 21 cases (chronic rhinosinusitis with nasal polyps, CRSwNP) group, 15 cases (chronic rhinosinusitis without nasal polyos, CRSsNP) group, 11 cases recurrent CRSwNP group and 13 cases control group. Positive cells were counted under the microscope artificially, Mann-Whitney U analysis was applied for the ranked data, and one-way anova analysis was adopted to analyze the experimental group and control group. RESULT: (1) TLR2 and TLR4 expression had the same characteristics. Expression mainly concentrated in parts of the whole layer of epithelial basement membrane, cytoplasm of glandular cells, very few inflammatory cells such as monocytes and plasma cells in the cytoplasm, sometimes unknown cell nuclei positive expression. (2) The glandular cells were stained manual counting and color grading. TLR2 and TLR4 packet application Wilcoxon rank test Mann-Whitney U test analysis was not statistically significant (P > 0.05), measurement data within the group variance statistical difference between the groups (P < 0.05). CONCLUSION The Nasal mucosa can produce the innate immune factors TLR2 and TLR4. The different expression of TLR2 and TLR4 in the various clinical types of CRS suggests that they play the certain role in the pathogenesis of CRS.

OBJECTIVE To investigate the incidence rate of nasal septum fracture and it's influence on the effect of nasal bone reduction. METHODS Retrospective analysis of 212 cases of nasal fracture compared with nasal septum deviation were carried out. Among these cases 112 treated with nasal bone reduction only was called group A; the other cases were treated with nasal reduction concomitantly with septoplasty. Among them 58 cases were diagnosed with nasal septum fracture, it was called group B; 42 cases were diagnosed with nasal septum deviation, it was called group C. The postoperative nasal deformity rate was assessed, and the intraoperative findings of nasal septum contrast with preoperative CT diagnosis was analysed. RESULTS Three months after the operation, 27 cases (24.1%) of nasal deformity were found in group A; 9(9.0%) cases of nasal deformity were found in group B+C; septum fracture was found in 58 cases (100%) in group B and 30(71.8%) cases in group C introperatively. The diagnosis rate of nasal septum fracture by CT was 58.0%, while it's incidence rate was 88.0%. CONCLUSION More nasal septum fractures were observed introperatively than CT findings, and septoplasty concomitantly with nasal bone reduction can obviously reduce the rate of nasal deformity.
