Functional magnetic resonance studies of the reorganization of the human hand sensorimotor area after unilateral brain injury in the perinatal period.

Functional magnetic resonance imaging was used to map the hand sensorimotor area of hemiparetic adolescents and young adults who had suffered unilateral brain damage in the perinatal period. Unlike normal subjects, who exhibit cortical activation primarily contralateral to voluntary finger movements, the hemiparetic patients' intact hemispheres were equally activated by contralateral and ipsilateral finger movements. Our findings are consistent with previous clinical observations and animal experiments which suggest that the immature brain is able to reorganize in response to focal injury.     

尼莫地平复方丹参注射液治疗新生儿缺氧缺血性脑病疗效观察

目的观察尼莫地平联合复方丹参注射液治疗新生儿缺氧缺血性脑病(HIE)的疗效.方法 128例HIE患儿随机分为复方丹参注射液组32例,尼莫地平组,尼莫地平加复方丹参注射液,与对照组.结果复方丹参注射液组、尼莫地平组、尼莫地平加复方丹参注射液治疗组总有效率分别为81.3%(26/32)、80.0%(24/30)、97.1%(34/35),对照组总有效率为51.6%(16/31),P＜0.05.结论尼莫地平与复方丹参注射液在治疗HIE时有协同作用,疗效显著,未见副作用发生.     

反映手术间利用效率的统计指标与方法探讨

目的 探索反映手术室工作状态的指标和方法，为了解科室需求、合理利用手术室资源奠定基础。方法 提取医院局域网中有关手术安排、手术过程、麻醉等信息，通过常用统计指标、统计图表，反映手术室、手术科室、手术间的工作状态。结果 工作日手术问日均工作6．34小时，节假日日均工作0．6l小时。工作日13点后有近l／3的空台，14点后近l／2空台。个别手术间利用率偏低。结论 1．由在用手术间时点统计结果可见，14点后接台手术尚有一定潜力，节假日安排手术潜力更大；2．工作日间均工作时数已近满负荷，若要进一步提高手术间的利用，需加强麻醉科和手术室力量。     

乙型肝炎病毒感染对机体免疫功能影响的研究进展

机体免疫功能的紊乱是乙型肝炎发病的重要因素.HBV感染可以引起多种免疫细胞(如DC、淋巴细胞、NK/NKT细胞)的功能障碍,包括表面分子表达的异常,分泌细胞因子的异常和亚型比例失调等.凋亡也是肝组织损伤和淋巴细胞功能障碍的原因之一.     

A study on various symptoms of chronic hepatitis treated with radix astragali and its regulative effect to levels of serum hormone

Sixty-seven cases of chronic hepatitis were treated with Radix Astragali. After treatment (2-month course), the clinical improvement rate in 38 cases of the Stagnation of the Liver-Qi and Deficiency of the Spleen type was 92.1%, and in 26 cases of the Deficiency of Liver Yin and Kidney Yin type was 88.5%, more effective than in the control group (P<0.05). The regulative effect to the levels of serum hormone was observed in the patients of the Stagnation of the Liver-Qi and Deficiency of the Spleen type treated with this medicine. The results showed that the levels of serum triiodothyronine, estradiol (female) and testosterone (male) were increased after treatment (1.40±1.38 ng/dl, 129.30±1.23 pg/ml and 496.24±1.47 ng/dl). Pre-treatment levels were 1.22±1.49 ng/dl, 104.60±1.45 pg/ml and 398. 17±1.55 ng/dl respectively (P<0.05); however, the level of serum prolactin (2.75±4.46 ng/ml) was lower after treatment than before treatment (3.20±3.82 ng/ml,P<0.05). No obvious changes were observed in the levels of serum follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, thyroxine, triiodothyronine uptake ratio and cortisol after treatment.     

扩大经额硬膜外入路切除巨大侵袭性垂体瘤

目的:探讨采用扩大的经额硬膜外入路切除巨大侵袭性垂体瘤的临床应用.方法:1997年6月至2002年3月采用该入路显微外科切除巨大侵袭性垂体瘤10例,肿瘤主要累及于鞍上、蝶筛窦及上斜坡区.结果:本组10例中,肿瘤全切6例,次全切除3例,大部分切除1例.术后发生颅神经麻痹4例,其中动眼神经障碍3例,外展神经障碍1例.全组无手术死亡.术后影像学随访6～24个月,全切除肿瘤病例未见肿瘤复发,次全切除者无明显增大.结论:该入路可充分显露鞍区肿瘤,术野开阔,对脑组织损伤小,适用于已侵犯蝶筛窦区及上斜坡的侵袭性垂体瘤.     

Early antenatal sonographic diagnosis of conjoined syncephalus-craniothoraco-omphalopagus twins. Case report.

The paper describes the prenatal ultrasonographic diagnosis of conjoined syncephalus-craniothoraco-omphalopagus twins at 13 weeks' gestation. The mother, after genetic counseling, decided to interrupt the pregnancy. The fetal karyotype, the maternal serum and amniotic fluid alpha-fetoprotein levels were normal. The diagnosis was confirmed by pathologic examination of the fetus after termination of pregnancy.     

男性不育症患者中YRRM2基因缺陷的研究

YRRM基因是控制精子生成与成熟的一个重要因素，一旦该基因缺陷，将会造成无精或少精。本研究对340例无精与少精患者的外周血标本进行了PCR基因扩增筛查，结果发现7例为该基因缺陷，占2％。证明YRRM2的缺陷也是造成中国人群男性不育的一个原因，从而可作为指导医生采用适当治疗方法的一个可靠指标。在实验过程中，采用直接加热白细胞提取基因组DNA，并以此作为模板对YRRM2基因进行扩增，既节省时间和经费，又保持良好的扩增效果，使之可用于临床医院作为常规检查。
