Objective To study the effect of temperature on the emission of tbrmaldehyde trom the blockboard.Methods A 0.25 m3 simulation chamber was used to explore the emission of formaldehyde from blockboard at the temperature of 15,17,19,21, 23,25,27,and 29 ℃,respectively.The relative humidity,the ventilation velocity and the loading factor in simulation chamber was (50?1)%,1.0 L/min,and(1?0.03)m~2/m~3 respectively.Results A hyperbolic logarithm variation in formaldehyde concentration with time in the chamber was observed at different temperatures.Formaldehyde concentration in the chamber increased remarkably once the temperature exceeded 25 C.The chamber stabilization formaldehyde concentration varied with temperature in accordance with an exponent equation of y=0.921 9?0.024 9e~(0.176 4x)(R~2=0.996 9).Conclusion The temperature can greatly influence formaldehyde emission from the blockboards.Higher temperature will facilitate formaldehyde emission from the blockboards.

Objective To investigate the technical feasibility and oncological safety of EPMR for early esophageal cancer and precancerous lesions. Methods Clinicopathological data, procedure quality and complications of 70 patients with early esophageal cancer or precancerous lesions were retrospectively ana?lysed. The technical safety and feasibility were assessed, and the complications were investigated through postoperative surveillance. The results were compared with published data from two high?quality meta?analysis studies on ESD. Results In a total of 70 patients who underwent EPMR, 35?7%( 25/70) were diagnosed as having early esophageal cancer and 64?3%( 45/70) atypical hyperplasia. And tumor size greater than 2 cm was 78?6%(55/70). The mean EPMR time was(28?31±9?49) minutes. The R0 resection rate of EPMR was 88?6%(62/70) and no perforation occurred. The bleeding rate was 21?4%(15/70). The esoph?ageal stricture rate was 1?4%( 1/70) . The recurrence rate was 2?9%( 2/70) . Compared with published ESD data from the two studies, EPMR showed shorter procedure time, lower curative rate and lower rates of stric?ture and perforation, but slightly higher rates of bleeding and recurrence. Conclusion Both EPMR and ESD are feasible and effective for early esophageal cancer and precancerous lesions. The curative results of EPMR are similar to ESD, with shorter procedure time, but higher bleeding and recurrence rates.

OBJECTIVE:To study the curative effects of Shenyanqing tablet.METHODS:1 200 patients with chronic glomerulonephritis,acute glomerulonephritis,latent glomerulonephritis and purpura glomerulonephritis were randomized into the treatment group and control group,and separately studied on curative effects and reduction of adverse reaction of glucocorticosteroid.In the study of curative effects,the control group received no special treatment except that on reducing pressure and diuresis,and the treatment group was given Shenyanqing tablet,8 tablets? d-1,tid,in addition to receiving same treatment as that for the control group.In the study of reducing adverse reaction of glucocorticosteroid,the control group(the treatment group was the same as the method above)was given normal glucocorticosteroid treatment for 3 months and 2 months respectively.RESULTS:It has significant difference(P

Objective To evaluate value of narrow band imaging(NBI) endoscopy for children with abdominal Henoch?Schonlein purpura ( HSP ) . Methods A total of 46 patients with abdominal HSP were enrolled into the observation group(NBI intervention) from November 2010 to February 2016.Diagnostic rates of white light and NBI endoscopy in abdominal HSP patients, IgA positive rates of targeted biopsies and severe complications were retrospectively analyzed. A total of 25 abdominal HSP patients with no NBI intervention admitted from 2007 to 2009 were randomly enrolled into control group. Data of the control group were compared with those of observation group. Results In observation group, the diagnostic rate under NBI was significantly higher than that under white?light endoscopy[91. 3%(42/46)VS 67. 4%(31/46),χ2=8. 02,P<0. 05]. IgA positive rates of targeted biopsies under NBI was significantly higher than that under white?light endoscopy [ 95. 7%( 88/92 ) VS 69. 6%( 64/92 ) ,χ2 = 21. 79, P<0. 05 ] . Three patients developed such serious complications as digestive hemorrhage as predicted. Compared with control group, abdominal pain and blood stool relief time (10. 96±5. 32 d VS 19. 68±4. 29 d,t=7. 50,P<0. 01), fasting time(10. 37±5. 42 d VS 8. 80± 3. 71 d,t=7. 73,P<0. 01), hospital stay (18. 80±7. 11 d VS 23. 12±4. 36 d, t=3. 16,P<0. 01), time of stool occult blood negative ( 11. 41 ± 6. 30 d VS 19. 12 ± 4. 09 d, t=6. 22, P<0. 01 ) in observation group were significantly shortened. Conclusion NBI endoscopy is valuable for improving the diagnostic accuracy and biopsy accuracy and complication prediction of abdominal Henoch?Schonlein purpura in children.

Objective To evaluate the correlation of inflammatory severity between appendiceal ori-fice inflammation(AOI)and ulcerative colitis(UC). Methods A retrospective analysis of the patients who were diagnosed as UC was conducted to investigate the correlation of the severity of inflammation between AOI and UC by linear trend test. Results The detective rate of UC during the above period was 2. 3%(991/ 42 928),with the patient number of 991.Appendiceal orifice observation did not perform in 45 cases due to patients reasons. In 946 patients,260 cases were diagnosed as having AOI,which accounted for 27. 5%of the total cases examined.AOI positive rates were significantly different between groups based on endoscopic severity standard(χ2 = 27. 39,P<0. 05),which was similar in moderate and severe group[30. 2%(109/ 361) VS 29. 8%(147/ 493),P>0. 0125],both significantly higher than that in mild group[4. 3%(4/ 92),P<0. 0125]. In linear regression analysis,regression coefficient was 0. 32,χ2return = 29. 48(P<0. 05)and χ 2partial =31. 66(P<0. 05),which proved a positive correlation between the two drawn existed but not a simple linear relationship. Conclusion AOI is a sign in some active UC patients. Its severity of inflammation can reflect the degree of inflammation in UC,which may offer a terminal point when treating a slice of UC individuals and giving a signal of its relapse.

Objective: To investigate the inhibitory effect of Undaria pinnatifida polysaccharides (UPPS) on hepatocellular carcinoma HepG-2 cells and its possible mechanism. Method: The effect of inhibiting proliferation and inducting apoptosis of UPPS were determined by means of MTT and FCM. The expression of Bcl-2 and Bax proteins was immunohis to chemcally evaluated after treatment of UPPS. Results: UPPS inhibited HepG-2 cells growth in vitro , significantly higher than the negative control group (P
