目的:评价4种根管封闭剂的生物相容性.方法:本实验通过X射线能谱仪对MTA、AH Plus、Roeko Seal、Cortisomol 4种根管封闭剂进行元素分析,并采用CCK-8法检测各材料凝固后即刻和1周时在100%和50%两种浸提液浓度下对L-929细胞的体外细胞毒性作用.结果:同一固化时间组内两种浸提液浓度相比,AH Plus组无论是固化即刻组还是固化后1周组,当其浸提液浓度为100%时,1、2、4d各时间点的细胞增殖率均低于50%浸提液(P<0.05),而其他3种封闭剂的即刻组和1周组样本中100%与50%浓度浸提液相比,各时间点的细胞增殖率均无显著性差异(P>0.05).同一时间点内各封闭剂相比,无论是固化即刻还是固化后1周组,其浸提液浓度无论是100%还是50%,各时间点的细胞增殖率由高至低依次为MTA组、Roeko Seal组、AHplus组、Cortisomol组;MTA 组与Roeko Seal组相比P>0.05,其他各组间比较P<0.05.结论:MTA 与Roeko Seal的细胞毒性最小,AH Plus的细胞毒性居中,Cortisomol的细胞毒性最大,但毒性级均未超过3级.

目的 研制一种易学、易掌握、易操作的新型弹力加压敷料,以替代部队长期装备的三角巾.方法 将不同大小的脱脂棉垫、弹力绷带和尼龙搭扣制成大、中、小三种型号的弹力加压敷料,用以包扎全身各部位体表伤口.同时与三角巾比较战士掌握使用方法的时间、战救操作的时间以及伤员活动后伤口包扎的牢固性.结果 弹力加压敷料可完成三角巾所有的包扎任务,战士掌握使用方法的时间、战救操作的时间明显短于三角巾,伤员活动后伤口包扎的牢固性明显强于三角巾(P＜0.05).结论 此新型战救弹力加压敷料可有效、快速、牢固地对全身各部位体表伤口进行包扎,易于学习、掌握和操作,可以作为三角巾在包扎方面的升级替代品.

OBJECTIVE:To introduce a modified model for quantitative testing of glucose microleakage by constant air pressure and evaluate the sealing ability of four root canal sealers including AU Plus, Roeko Seal, Cortisomol and RC Sealer.METHODS:Fifty-six straight maxillary anterior teetb were randomly divided into four experimental groups with 12 samples in each group, group A: AH Plus, group B: Roeko Seal, group C: Cortisomol, group D: RC Sealer, and positive and negative control group with 4 samples in each. After regular root preparation, samples in experimental groups were obturated by cold gutta-percha lateral compaction technique with sealers according to group description. Control groups were obturated with cold gutta-percha only. Through the model above, the value of glucose microleakage from crown to root was measured at 1, 3, 5, 7, 10, 15, 20, 25, 30 days with the glucose oxidase-peroxidase method (GOD-POD).RESULTS:At day 1, 3, 5, no significant difference of microleakage was found between group A and B (P > 0.05). The same result was also seen between group C and D. From 7 days, microleakage value in each experimental group gradually increased, and statistical difference was found between groups (P < 0.05).CONCLUSION:This new model using constant air pressure is easy to establish, sensitive and practical. Among all the sealers evaluated, polydimethylsiloxane based root canal sealer, Roeko Seal has the greatest sealing ability, while epoxy-amine resin based AH Plus is second and Zinc Oxide based Cortisomol and RC Sealer have the least sealing ability.

魏杰(陕西) 我们知道,篆刻艺术传统不出两大系统,即战国、秦、汉印系统和元、明、清以降的篆刻流派作品系统.就前者而言,学习篆刻则必须走过秦汉印阶段,所谓『印宗秦汉』正是这个意思.但是从秦汉印过来的印人往往在创作中又摆脱不了秦汉印的藩篱,即便是浙派的创始人丁敬、蒋仁在刀法上已有巨变,但大体上仍是汉印的框架并导致了印面的呆板和章法的单一,当然,这有历史的局限,但现今已少有人取法.

目的了解某部机关官兵鼾症发病情况及相关因素,为防治工作提供依据。方法调查了1 505名官兵的鼾症发病情况。采用问卷形式,测量颈围、体质量指数(BMI),并对日常工作状态及相关因素进行了分析。结果 1 505名官兵中有259例鼾症患者,发病率为17.2%。鼾症组的颈围、BMI明显大于正常对照组(P<0.01),超重和肥胖体型者的鼾症发生率明显高于正常体型者。结论某部机关官兵鼾症的发生与肥胖及上呼吸道阻塞性疾病有关,严重者对日常工作有一定的影响。

AIM: To study the effect of different adhesive systems accompanied with silane agent on the bond strength of fiber post in root canals.METHODS: The crowns of thirty-two freshly extracted sound mandibular central incisors were cut.The root canals were prepared and filled.Then a 5mm-deep post space was made(Φ1.25mm).The roots were randomly divided into 4 groups(n=8) and posted with fiber posts and different adhesive systems: silane+ParaCore group,ParaCore group(control),silane+RelyX Unicem group and RelyX Unicem group(control).The samples were then subjected to universal mechanical testing machine for pull-out test.RESULTS: The pull-out bond strength(MPa) of the four groups were 11.4±3.7,12.1±2.7,5.2±1.0 and 4.9±1.2 respectively.No matter silane was applied or not,the bond strength of ParaCore group was significantly higher than that of RelyX Unicem group(P0.05).When the same adhesive system was used,no statistical difference was found between silane group and the control group(P0.05).CONCLUSION: The bond strength of fiber post(ParaPost Taper Lux)is related to resin adhesive systems.In our experiment,ParaCore system showed better effects than RelyX Unicem system.The application of silane coupling agent failed to affect the pull-out bond strength.

目的探讨倒班军人睡眠质量与心理健康的关系。方法采用匹兹堡睡眠质量指数(PSQI)和症状自评量表(SCL-90)问卷对驻京113名从事倒班工作的军人进行调查。结果倒班军人PSQI总分为6.82±3.56。以PSQI总分≥8分作为判断睡眠质量存在问题的标准,有37.17%的倒班军人存在睡眠质量问题,主要体现在入睡时间(51.3%)、睡眠效率(36.3%)和睡眠质量(34.5%)成分上。影响倒班军人睡眠质量的主要问题为入睡困难、夜间易醒或早醒,其>1～2次/周的百分比分别为38.9%和29.2%。倒班军人PSQI总分及大多数成分与SCL-90各因子及总均分呈显著性正相关。结论部分倒班军人的睡眠状况较差。睡眠质量与心理健康相关。
