Objective To explore influencing factors for complete resection and operation time of endoscopic submucosal dissection( ESD) for colorectal tumors. Methods This retrospective study included 95 consecutive colorectal tumors in 88 patients whose pathological diagnosis was adenoma and carcinoma, treated with ESD at the Department of Endoscopy of the First Hospital of Jilin University from January 2013 to December 2014. Multiple logistic regression analysis was conducted on the factors related to complete resection and operation time. Results Average tumor size was 28. 7±14. 1 mm(range,8?80 mm), and the average procedure time was 80. 72±63. 90 min. The rate of complete resection was 92. 6%(88/95),and the rate of incomplete resection was 7. 4%(7/95). Multivariate logistic regression analysis revealed that fibrosis (P=0. 012,OR=52. 473, 95%CI:2. 571?1140. 438) contributed to incomplete resection. Fibrosis ( P=0. 001, OR=0. 045, 95%CI:0. 007?0. 289) ,tumor size ( P=0. 035,OR=0. 170, 95%CI:0. 033?0. 884) ,granular?type laterally spreading tumor ( P=0. 013, OR=34. 432, 95%CI:2. 138?554. 476 ) , non?granular?type laterally spreading tumor(P=0. 044,OR=31. 715, 95%CI:1. 093?919. 904) were independent factors for extending operation time of colorectal ESD. Conclusion The severer fibrosis can induce higher rate of incomplete resection. The more severe fibrosis is, the larger tumor size is, and the longer operation time is.

Objective To establish and test the reliability and validity of the disease related psychological pressure scale of pregnant women with chronic HBV infection,so as to provide mental stress assessment tool for the pregnant women.Methods Item pool was developed after the interview and comprehensively retrieved literatures,then after expert review and rebuilt,the scale items were fixed.Totals of 368 pregnant women with chronic HBV infection disease were investigated and the reliability and validity of scale were test.Results The scale had 5 factors and 24 items,and the correlation coefficient between each factor score and total score was 0.712 - 0.894.The correlation coefficient among each factor was 0.409 - 0.631 which was significantly lower than that between each factor score and total score ( P ＜ 0.01 ).The cumulative contribution rate of 5 factors was 64.055％,and tes-retest reliability of 5 factors was 0.856,0.887,0.828,0.813.The Cronbach' s α of internal consistency of 5 factors was 0.788 - 0.865,and the Cronbach' s α of scale was 0.932.Conclusions The scale has good reliability and validity,and can be used for measuring the disease related pregnancy psychological pressure for chronic HBV infection pregnant women.

Molecular methods and fluoroscopic techniques suggest that rich microbial diversity exist in the marine environment, but less than 1% of these microbes can be cultured in the laboratory conditions, and that the cultivable dominant species were even less. This limitation has long been a barrier to the development of environmental microbiology and the utilization of marine resources. In the past decade, novel methods for culture and detection of these uncultured marine microbes have successfully applied to obtain several conventionally-uncultured microbes including those from extreme environments. Those progresses have inspired researchers greatly. Developments in the research of marine microbial resources are an important basis for the study of the micro-world and deserve increasing scientific attention.

AIM:To compare the refractive errors measured by the VISX WaveScan, OPD - Scan Ⅲ and the subjective refraction.
METHODS: Seventy - six patients ( 152 eyes ) were recruited from January 2013 to December 2013. All patients were measured with subjective refraction by the phoropter (NIDEK, RT-5100), objective refraction by the WaveScan ( AMO Company, USA) , OPD-ScanⅢ ( Nidek Technologies, Japan). The sphere, cylinder, axis of the three methods were compared and analyzed.
RESULTS: The sphere measured by WaveScan was lower than that by subjective refraction, the difference was 0. 13±0. 30D (t=3. 753, P<0. 001). For cylinder, the difference was 0. 13±0. 43D (t=3. 664, P<0. 001). There was no significance for sphere, cylinder, and spherical equivalent between OPD - Scan Ⅲ and subjective refraction (P>0. 05). The value of the difference between WaveScan and subjective refraction was 5. 87o±6. 19o for the axis and the difference between OPD-Scan Ⅲ and subjective refraction was 3. 82o±3. 95o. There was statistic significance (t=2. 817, P=0. 006).
CONCLUSION: For sphere and cylinder, WaveScan generated some deviation relative to subjective refraction. The Nidek OPD-ScanⅢ gives more accurate measures of objective refraction when compared with subjective refraction.

The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.
