部分性脾栓塞术并发症23例分析

采用部分性脾栓塞(Partial Splenic Embohzafion，IXSE)治疗肝硬化并发脾功能亢进能够有效地缓解脾功能亢进、改善外周血象，同时还保留了部分脾脏以完成其免疫功能，因而PSE已经成为替代外科脾切除的首选的治疗方法。但是PSE术后易出现一些并发症，若处理不当可能会影响脾栓塞的疗效，导致患者病情加重，甚至死亡。为此，本文对我院23例PSE术的并发症进行报告，并对其发生原因及其处理方法加以讨论。     

丁螺环酮和阿普唑仑治疗广泛性焦虑研究

目的：比较国产丁螺环酮和阿普唑仑治疗广泛性焦虑的疗效和不良反应。方法：对78例广泛性焦虑按照就医顺序分为两组，分别服用丁螺环酮(38例)和阿普唑仑(40例)。疗程6周。于治疗前及治疗第1、2、4、6周末进行汉密尔顿焦虑量表(HAMA)及副反应量表(TESS)评定疗效和不良反应。结果：丁螺环酮和阿普唑仑的疗效相仿，丁螺环酮的不良反应少且轻微，无过度镇静和肌肉松弛作用，不产生药物依赖。结论：丁螺环酮是治疗广泛性焦虑较为理想的药物。     

Thrombocytopenia after therapeutic hypothermia in severe traumatic brain injury

Objective: To investigate the clinical characteristics and significance of thrombocytopenia after therapeutic hypothermia in severe traumatic brain injury (TBI). Methods:Ninety-six inpatients with severe brain injury were randomized into three groups: SBC (selective brain cooling) group (n=24), MSH (mild systemic hypothermia ) group (n=30), and control (normothermia) group (n=42). The platelet counts and prognosis were retrospectively analyzed. Results: Thrombocytopenia was present in 18 (75%), 23 (77%) and 15 (36%) patients in SBC group, MSH group and control group, respectively (P<0. 01). Thrombocytopenia, in which the minimum platelet count was seen 3 days after hypothermia, showed no significant difference between SBC and MSH group (P>0.05). Most platelet counts (37 cases, 90 %) in hypothermia group were returned to normal level after 1 to 2 days of natural rewarming. The platelet count in SBC group reduced by 16%, 27% and 29% at day 1, 3 and 5 respectively compared with the baseline value. Good recovery ( GOS score 4-5) rate of thrombocytopenia 1 year after injury for hypothermia group (17 cases, 37%) was significantly lower than that of control group (P < 0.01). Conclusions: Therapeutic hypothermia increases the incidence of thrombocytopenia in severe TBI, and patients with thrombocytopenia after therapeutic hypothermia are associated with unfavorable neurological prognosis.     

缺血性脑白质病变的影像学评估

Epidemiology of age-related dementia in China.

Since the early 1980s, China has confronting adramatic change in population structure as well as arapid aging process. The proportion of the elderlyhas been increasing nation wide, and dementia is be-coming a major public health problem. However,the distribution of dementia among the aged, itsprevalence and incidence were unknown.Anepidemiological program was initiated in 1986 to in.vestigate this disorder in a community--based agedpopulation and to identify the possible risk factorsof Alzheimer's disease through collaboration withnine psychiatric hospitals in China, headed by the In-stitute of Mental Health, Beijing Medical University.     

绵毛黄芪苷和苦玄参苷的中枢抑制作用

报道了绵毛黄芪苷(SK)及其同类结构苦玄参苷(PIA)给予昆明种式BLC_(57)/1小鼠50mg/kg腹腔注射能明显延长硫贲妥钠的睡眠时间,用扭体法或热板法证实同量SK或PIA静脉注射能产生明显的镇痛作用。用格斗试验证实:同量SK或PIA腹腔注射可使小鼠格斗试验次数明显减少。提示两种苷可能具有中枢镇静、镇痛和安定作用;此类中枢抑制作用说明四环三萜皂苷类具有药用价值的前景。     

前牙反缺失修复法

作者用“粘膜术与牙体修复术”相结合方法，成功地修复了成人畸形的前牙和个别前牙缺失的修复问题。经过一年来20例临床病例观察，达到快速满意的疗效。现报告如下。修复方法一、对畸形、错位的成人前牙修复法；1．局麻下唇面开髓，作常规根管治疗，很充后观察一周。2．用邻牙或相对牙作参照牙，切割转位牙、斜输锥形牙的影响修复部份的唇侧牙冠；反路牙调磨解除反。所有牙切端均用砂轮磨短并形成舌侧切斜面，以便将来用复会树脂粘固塑料牙片时切端包绕过来，以加强切端固应力、（注：本文所用的复合树脂是上海青浦齿科材料厂出产的H一18超…     

K562／ADM耐药细胞株的建立及其生物学特性的初步观察

我们建立的K562/ADM耐药细胞株,在ADM浓度为2.4μg/m1(4.46μM)中已稳定培养3.5个月,传了30—35代,K562/ADM亦具有多药耐受件(Multidrug Resistance,MDR)的特点,对ADM、VCR、AT—1258和DDP的耐受性分别为K562的114.7、94.0、13.3和7.4倍,但对5—FU不产生交叉耐药。K562和K562/ADM的倍增时间分别为19.2h和52.8h,集落生成率分别为37.5％和11.1％,K562染色体数为34—68,中位数为56;K562/MDM染色体数为32—90,中位数为50,K562/ADM可做为耐药机理和克服耐药措施研究的极好模型。
