Objective To investigate expressions of microRNA-21 (miR-21),PTEN,NF-κB,and caspase-9 in colon carcinoma and their possible mechanisms in progression of tumor.Methods Expressions of above-mentioned indexes and percentage of apoptotic cells in colon carcinoma,colon adenoma,and normal tissue specimen were detected.Results Expressions of miR-21,PTEN,N F-κB,and caspase9 in normal tissue were 0.39 ±0.02,50％,25％,and 50％.Expressions of them in colon adenoma were 0.62 ±0.06,50％,35％,and 55％,and those in colon carcinoma were 0.88 ±0.04,30％,75％,and 20％.Percentage of apoptotic cells were (24.64 ± 7.66) ％,(15.86 ± 1.44) ％,and (6.20 ± 2.57) ％,respectively.The above P-values were all less than 0.05.Expression of miR-21 was positively correlated with TNM stage,depth of infiltration,differentiated level and expression of NF-κB while inversely correlated with PTEN and caspase-9 expressions and percentage of apoptotic cells.The r-values were 0.647,0.297,0.259,0.519,-0.299,-0.388,and-0.931,respectively.Conclusions Hyperexpression of miR-21 participated in progression of colon carcinoma probably through down-regulating expressions of PTEN and caspase-9 and up-regulating expression of NF-κB and then suppressing cell apoptosis.

Objective:To observe the anatomic characteristics of supratubal recess and the morphological change of it in the sick ear. To investigate the relation between the morphological changes of supratubal recess and otitis media.Method:Using high resolution CT to observe and measure the supratubal recess of the normal ears and the ailing ones.Result:For the normal adults, the anteroposterior diameter of the supratubal recess is(3.83±1.28)mm,the vertical diameter(3.67±1.14)mm,the height(3.76±0.36)mm;and the length of the cog is(2.84±0.38)mm.The size of the supratubal recess showed no significant difference between left and right(P＞0.05).There was no relationship between the size of the supratubal recess and pneumatization of mastoid cells (P＞0.05).There was significant differences in size of the supratubal recess between normal ears and the ears with cholesteatoma(P＜0.05),but there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells(P＞0.05)in the ears with cholesteatoma.There was no significant differences in size of the supratubal recess between normal ears and the ears with chronic otitis media(P＞0.05).In the ears with cholesteatoma,40% had osseous destruction in supratubal recess.Conclusion:For the normal adults, the size of the supratubal recess showed no significant difference between left and right, and there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells. Anterior tympanic isthmus , posterior tympanic isthmus and supratubal recess which is the supplement of the formers constitute the air way between attic and mesotympanum. The supratubal recess of the cholesteatoma is smaller than the normal, when the eustachian tube dysfunction occurs, the air way in the middle ear would herein be affected, and cholesteatoma forms eventually. There was no significant differences in size of the supratubal recess between normal ears and ears with chronic oti-tis media, as in the clinic.The effect of the supratubal recess should be taken into account when we consider the pathogeny and treatment of the middle ear cholesteatoma.

Objective To assess the interobserver reliability and intraobserver reproducibility of Neer classification system and its influencing factors.Methods The present study reviewed the series preoperative radiographs (including those of scapular anteroposterior view,scapular lateral view and modified Velpeau axillary view and an axial CT scan) of 40 patients who had been treated in our department from January 2010 to December 2010 for proximal humeral fractures.The radiographs were assessed by 12 individual observers on 2 separate occasions with an interval of 3 months at least Half of the observers (the professional group; n =6) had received a shoulder fellowship training and the other half (the control group; n =6) had not All the observers were asked to categorize the radiographs according to the Neer classification system of 16 types of fractures in a same process.The reliability and reproducibility of the system were assessed with the Kappa statistics.Comparisons of classification agreement were made between the professional group and the control group.We also evaluated the simplified Neer system of only 6 types of fractures with recombinant data.Results The interobserver reliability coefficients were 0.534 and 0.473 for the first and second assessments,with an intraobserver reproducibility coefficient of 0.669.The agreement level in the professional group was significantly higher than in the control group ( P ＜ 0.05).The interobserver reliability coefficients of the simplified Neer system were 0.581 and 0.502,with an intraobserver reproducibility coefficient of 0.680.Use of the modified Neer system did not elevate the agreement level beyond the moderate range.The classification was agreed on by all the observers in 17.5％ of the fractures during the first assessment and in 15.0％ during the second assessment.Conclusions Neer classification may have fair interobserver reliability and moderate intraobserver reproducibility.Experience of shoulder fellowship training is an important factor influencing the reliability of the Neer system.Simplification of the system may not help increase its reliability.

Objective To study the effect of Xuebijing, a Chinese traditional medicine injection, on the THP-1 cells challenged by endotoxin, and to explore whether it induces endotoxin tolerance. Methods The THP-1 cells were pretreated with Xuebijing in different concentrations (10, 25, 50 mg/mL) and times (4, 12, 24 hours), and then challenged by endotoxin. The level of TNF-α in culture supernatant was detected by ELISA assay, and the expression of TLR4 and IRAK-M mRNA were detected by Real time-PCR technique. Results There was no significant difference in TNF-α level among all the groups (pretreated with different concentrations of Xuebijing for different time) (P>0.05). Only in 50 mg/mL Xuebijing group, TLR4 mRNA was 1.547-fold increase in 24 h than in 4 h group (P<0.05). Only when pretreated for 24 h, IRAK-M mRNA was 1.349-fold increase in 50 mg/mL Xuebijing group than in control group (P<0.05). However,there was no significant difference among other groups (P>0.05). Conclusions Xuebijing can not block the release of TNF-α from the THP-1 cells challenged by endotoxin;and it does not induce endotoxin tolerance. When pretreated with high concentration of Xuebijing for long time, the expression of both TLR4 and IRAK-M mRNA is up-regulated, but its significance is not yet clear.

BACKGROUND: A variety of cages for lumbar interbody fusion have been used, which have good mechanics and clinical effects. Conventional posterior fusion requires parallel implantation of two cages, but some researchers believe that single lumbar fusion cage in oblique way is also possible.OBJECTIVE: Through in vitro biomechanical tests, to find a method with favorable effect and little trauma by combination of percutaneous lateral oblique way into the single expansive lumbar fusion cage between the fixed-line operations.DESIGN, TIME AND SETTING: A randomized, controlled experiment was performed at the Shanghai Institute of Biomechanical Engineering between May 2005 and May 2008.MATERIALS: Expansile lumbar interbody fusion cage was simulated from B-Twin Cage (Disc-O-Tech, Israel). Fresh calf lumbar specimens were used.METHODS: Biomechanical tests were performed in 18 specimens of calf lumbar function spinal units (FSU), which were divided into 3 groups: 6 in control group, 6 in single cage groups and 6 in two-cage groups. The biomechanical tests of two experimental groups were performed following tests of intact specimens. Stiffness tests were conducted in the WE-10A MTS,including axial compression, flexion, extension, lateral bending, and torsion.MAIN OUTCOME MEASURES: Axial and torsion stiffness results of each group.RESULTS: The stiffness was greater in two-cage groups compared with single cage group in axial compression and extension, but significant differences were only found in axial compression and extension tests (P < 0.05). The torsion stiffness of single cage group was significantly greater than two-cage groups (P < 0.05).CONCLUSION: Percutanous lumbar interbody fusion by single expansile lumbar interbody fusion cage from lateral approach is feasible theoretically. Biomechanical properties of FSU with B-Twin cage are improved, which contributes a lot to lumbar stability. Compared with posterior approach of single cage, two-cage can provide better stiffness and stability but its torsion stability is lower.
