目的：观察针药结合治疗假性延髓麻痹的疗效。方法：采用完全随机抽样法分为针刺组50例，对照组48例。针刺组在西医治疗的同时，应用针刺进行综合治疗；对照组单纯接受西医药物治疗。结果：针刺组有效率为92．0％，对照组为62．5％。两组疗效差异具有非常显著性意义（P〈0．01）。结论：针药结合治疗假性延髓麻痹效果明显优于单纯西药治疗。     

The modified outside-in suture: vertical repair of the anterior horn of the meniscus after decompression of a large meniscal cyst

This article describes a modified suture technique designed for the vertical repair of the anterior horn of the meniscus after arthroscopic decompression of a large meniscal cyst. This procedure comprises of three steps: first, the meniscus was pierced vertically using a suture hook and a No. 0 PDS suture. Second, both ends of the No. 0 PDS on the femoral and tibial surfaces of the meniscus were pulled to the outside of the joint capsule using a spinal needle preloaded with suture material. Finally, a skin incision was made adjacent to the suture materials, and both ends were tied. We recommend this technique not only for the vertical repair of the anterior horn of the meniscus after decompression of large meniscal cyst, but also to repair a longitudinal tear of the meniscus.

Cortical plasticity: effect of high and low intensity conditioning electrical stimulations (100 Hz) on SEPs to painful finger stimulation.

OBJECTIVE: To study the effect of high-frequency (100 Hz) repetitive conditioning electrical stimulation (CES, 10 min) on human somatosensory evoked potentials (SEPs) to evaluate if short-term cortical plasticity could be induced. METHODS: Painful electrical stimulations were applied to thumb (D1) and little finger (D5) fingertips, respectively. The 124-channel EEG was recorded from 10 healthy male volunteers. Peak stages around 34, 45, 212, 331 ms were analyzed with focal maximum amplitude (FA) and area magnitude (AM) of scalp field potential, topography, and equivalent current dipole source localisation, comparing before and after two-level CES (high- vs. low-level) applied to the He-Gu acupoint. RESULTS: After a high-level CES, the positive FA and AM of the current efflux showed a significant increase at the early phase 34 ms, and significantly decreased at 45 ms in D1 SEPs. The negative FA and AM of the current influx were significantly increased at late phase 350 ms of the D5 SEPs. Only 36 ms, the z-axis position of dipole was significantly changed from (x: -15.9 mm, y: 29.6 mm, z: 43.9 mm) to (x: -12.9 mm, y: 29.4mm, z: 51.5mm) for the D5 SEPs. CONCLUSIONS: The high-level CES significantly attenuated the subsequent cortical activation (45 ms peak for D1 stimulation). Both low- and high-level CES significantly enhanced the late activities (226, 350 ms) in D5 stimulation. This may be explained by pain sensation change at the level of subcortical cingulate cortex induced by the site-dependent post-effect of CES. SIGNIFICANCE: This study showed cortical plasticity induced by conditioning somatosensory stimulation.

人Uroplakin Ⅱ启动子用于靶向性基因治疗膀胱癌的实验研究

目的探讨利用人UroplakinⅡ(hUPⅡ)启动子进行靶向性基因治疗膀胱癌的可能性。方法将hUPⅡ启动子和肿瘤坏死因子-α(TNF-α)克隆到腺病毒载体Ad5中,构建重组体pAd-hUPⅡ-TNF。转染细胞293后产生复制缺陷型的重组腺病毒,感染膀胱癌细胞系BIU-87,检测TNF-α对BIU-87细胞体外生物学行为及体内成瘤性的影响。结果成功构建pAd-hUPⅡ-TNF重组腺病毒载体,转染细胞293获得复制缺陷型重组腺病毒。BIU-87细胞经重组腺病毒感染后可产生高浓度的TNF-α,并降低BIU-87的生长速度。感染腺病毒的BIU-87培养液可抑制L929细胞的生长。裸鼠原位膀胱肿瘤动物模型实验结果表明膀胱灌注重组腺病毒48h后,裸鼠尿液含高浓度的TNF-α,4周后腺病毒组膀胱重量和体积明显低于对照组(P<0.01)。结论hUPⅡ启动子TNF-α为治疗基因的重组腺病毒可特异性使膀胱癌细胞系BIU-87产生高浓度的TNF-α,并降低BIU-87和L929细胞的生长速度。重组腺病毒可使裸鼠尿内含高浓度的TNF-α,并可抑制裸鼠原位膀胱肿瘤动物模型膀胱癌细胞的成瘤性。     

Genetic linkage analysis of pulmonary fibrotic response to silica in mice.

Inter-individual variations in the development of silicosis, even within the same environments, have been reported, which suggest the contribution of genetic factors in silicosis aetiology. The aim of the present study was to determine whether there is any significant genetic influence on the development of silicosis. Furthermore, which genetic loci are responsible for the pulmonary response to silica exposure? Eight strains of inbred mice were used to examine the genetic influence on the lung fibrotic response to silica exposure. After intercross-breeding between the most susceptible and most resistant strains, a genome-wide linkage analysis of quantitative trait loci (QTL) was performed. Hydroxyproline was applied as an index, and genotypes of 167 marker genes were analysed by fragment analysis using a capillary-type sequencer. There was significant inter-strain difference in the mean concentration of hydroxyproline contents among the eight strains of mice. Breeding studies were conducted between the most susceptible, C57BL/6J, and the most resistant strain, CBA/J. A genome-wide linkage analysis of silica-exposed intercrossed cohorts identified significant QTL on chromosome 4 and suggestive QTL on chromosomes 3 and 18. The present study demonstrates that genetic factors may play a significant role in fibrotic-lung responses to silica; one significant and two suggestive quantitative trait loci were identified.
