照射与免疫的时间间隔对抗体形成的影响及其辐射剂量效应

本实验观察了0. 25、0. 5、1. 0、2. 0、3. 0和4. 0Gy全身照射后3至6 h羊红细胞(SRBC)免疫对小鼠脾脏抗体形成细胞(PFC)的影响。结果发现,各剂量照射后,免疫与照射的时间间隔较长者,辐射对PFC反应的抑制显著加深。照射后3及6h免疫,脾脏PFC反应均随照射剂量的增加而降低。照射后3h免疫时,PFC反应的D_(37)值为4. 13Gy;照射后6h免疫时,PFC反应的D_(37)值为1. 74Gy。     

卫生行政部门公务员有效激励的多维度探讨

相比其他组织的就业人员，卫生行政部门公务员拥有事实上的和法律上的就职保障，这种保障对于保证国家卫生公共政策执行的连贯性、稳定性和激励高素质人才进入公务员队伍至关重要，但在现实中它对公务员的有效激励产生了一定的影响，该文从就职保障与在职激励之间的调适关系出发，就如何确保对卫生行政部门公务员的有效激励进行了多维度分析和探讨，解析了激励发生的深层次机理，并在方法和手段上提出了建议。     

我省医学临床教学基地建设的现状与思考

Tagawa髋臼旋转截骨术治疗髋臼发育不良的评价

目的　评价Tagawa髋臼旋转截骨术治疗髋臼发育不良的临床效果。方法　采用Tagawa髋臼旋转截骨术治疗髋臼发育不良 ,用Harris评分和测量X线髋臼指数来评估手术的临床效果和髋臼 股骨头解剖关系的变化。结果　Harris评分从术前的平均 ( 80± 7.7)分提高到 ( 95± 1.8)分 ,主要表现为疼痛明显改善。X线显示髋臼CE角、AC角、AHI获得明显改善 ,但HLI没有变化。所有病例没有重大并发症发生。结论　Tagawa髋臼旋转截骨术治疗髋臼发育不良能较好地重建髋臼和股骨头的解剖关系 ,可以明显改善患者髋部疼痛症状 ,延迟髋关节骨关节病的发生

大鼠脂肪干细胞复合胶原-壳聚糖-硫酸软骨素三维支架构建组织工程软骨

Objective To evaluate the character of the collagen-chitosan-chondroitin sulfate scaffold seeded with rat adipose tissue-derived stromal cells. Methods A dipose tissue were harvested from 6 weeks old Wistar rats and the stromal cells were harvested by type Ⅰ collagenase and then cultured in vitro. Type Ⅰ collagen was fully mixed with chitosan, freeze-dried and cross-linked with chondroitin sulfate, then freeze-dried again and sterilized by ethylene oxide. The pore diameter, water content, porosity of the scaffold were tested. The adipose tissue-derived stromal cells were digested, seeded into the plates, scaffold, and cen-trifuged into pellet, and then induced into cartilage. MTT detection for cell proliferation was done. After 3 weeks, the cell morphology, and cell proliferation and adhesion were observed, and chondrngenic differenti-ation was also analyzed. Results The pore diameter, water content, porosity tested for the scaffold showed an appropriate form. Cell proliferation showed faster in the scaffold and pellet culture system after 5 day, there was still cell proliferation in the scaffold system after 14 days but no obvious changes in the pellet cul-ture system; ceils on the scaffold proliferated densely showed by histological staining, but there was a scaf-fold structure residues in the inner layer. The finding of type Ⅱ immunohistochemistry stain showed that cells express strong positive for type Ⅱ collagen in the scaffold and pellet culture system whereas it was weakly positive in the plate culture system; the specific mRNA for cartilage, type Ⅱ collagen, aggrecan and SOX-9 were expressed in all three systems showed by RT-PCR, but type X collagen was expressed continu-ously in the plate culture system and expressed after 21 days in the pellet culture system, whereas it was not detected in the collagen-chitosan-chondroitin sulfate scaffold system. Conclusion The parameters of the collagen-chitosan-chondroitin sulfate scaffold were suitable in our study. The results suggested that it can promote the adipose tissue-derived stromal cells proliferation and chondrogenic differentiation better than the plate and pellet culture systems and maintain the phenotype of chondrocytes well; it is the optimal choice for cartilage tissue engineering in the future.     

精子洗涤对精液中HBV DNA含量的影响

目的：检查HBV感染者精液是否存在乙型肝炎病毒（HBV），探讨精子洗涤是否能去除其中的HBV DNA。方法：用实时荧光定量PCR（FQ-PCR）法检测57名血清HBsAg阳性患者精液中HBV DNA，采用Percoll非连续梯度离心及上游法分离其中21份精液，并对洗涤后标本进行HBV DNA检测。结果：62份精液标本中有15份HBV DNA阳性，阳性率为24.19%;21份用于洗涤的精液标本中有，有7份HBV DNA阳性，洗涤后仍有6份标本阳性。结论：部分HBV感染者精液具有传染性，精子洗涤不能完全去除精液中的乙肝病毒。将HBV感染者的精液用于人工授精或体外受精应慎重。
