螺旋CT三期扫描对肝纤维化诊断价值研究

目的探讨螺旋CT三期扫描对肝纤维化的诊断价值。方法对66例经肝穿刺活检病理证实的慢性乙型肝炎肝纤维化患者组和42例正常对照组进行螺旋CT三期增强扫描。根据纤维化程度分期进行影像资料和相关指标的统计分析。结果肝左叶增大,肝表面形态及肝实质密度的改变,脾脏增大,门静脉增宽和侧枝循环的建立等影像学改变,随着肝纤维化严重程度的加重而有统计学差异。本研究显示57例肝纤维化患者螺旋CT三期扫描诊断肝纤维化52例,敏感性91.2%,特异性77.8%。各期肝纤维化分期准确28例,准确率49.1%;准确判断轻度纤维化(S1、S2)或重度纤维化(S3、S4)44例,准确率77.2%,诊断早期肝硬化16例,准确率84.2%。结论螺旋CT三期扫描能判断肝纤维化的程度,而且是动态观察肝纤维化的病程演进和临床随访的有效手段。     

胰岛素强化治疗在2型糖尿病骨折患者围手术期的应用

Objective To investigate the best way to control the blood sugar level during the perioperation of bone fracture patients with type 2 diabetes(T2DM).Methods Bone fracture patients with T2DM were randomly divided into three groups:continuous subcutaneous insulin infusion group(insulin aspart,group CSII,n=20),glargine treatment group(insulin aspart+insulin glargine,group GA,n=20),and NPH treatment(insulin aspart+rh-insulin,group NA,n=20).The levels of fasting plasma glucose(FPG)and the 2 hours postprandial glucose(2h PG),blood glucose fluctuation(BGF),insulin dosage(ID),good effective time(GET),incidence of hypoglycemia,dawn phenomenon and infection,average time of stitches removal(ATSR),average hospitalized length(AHL)of three groups were compared.Results FPG and 2hPG,ID in group CSII[(6.32±1.18)mmol/L,(7.72±1.53)mmol/L,(35.40±1.60)IU]and group GA [(6.25±0.88)mmol/L,(7.32±1.17)mmol/L,(36.20±0.80)IU]were significantly lower than those of group NA [(7.44±1.36)mmol/L,(8.52±0.76)mmol/L,(40.50±2.40)IU,all P<0.05],simulaneously,BGF,GET incidence of complications,ATSR,AHL of group CSII and GA were significantly lower than those of group NA(all P<0.05).There were not significant difference between group CSII and group GA.Compared with group CSII,group GA had less costs in-hospital and better practicability.Conclusion Both CSII and insulin glargine combined with insulin aspart can effectively,safely,rapidly and stablely control hyperglycemia.and might be the first choice to control blood sugar for bone fracture patients with T2DM in perioperation.     

Synthesis and anti-tuberculous activity of diesters based on isosteviol and dicarboxylic acids

Diesters based on isosteviol and dicarboxylic acids were synthesized and tested for antituberculous activity. Isosteviol and some of its derivatives exhibit appreciable tuberculostatic properties in vitro, the activity being dependent on the length of the polymethylene spacer connecting two ent-beyeran fragments. The mechanism of the antituberculous action of isosteviol derivatives are discussed. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 40, No. 9, pp. 12–13, September, 2006.     

JAK2激酶抑制剂AG490对结肠癌HT-29细胞侵袭性的影响

目的观察JAK2激酶抑制剂AG490对结肠癌HT-29细胞侵袭以及对基质金属蛋白酶-2（MMP-2）表达的影响，探讨STAT3信号转导通路在结肠癌侵袭转移调控中的作用。方法应用JAK2激酶抑制剂AG490处理结肠癌HT-29细胞，Matrigel肿瘤体外侵袭模型检测肿瘤细胞侵袭；Western blot检测STAT3蛋白表达；逆转录-聚合酶链反应（RT—PCR）检测MMP2mRNA表达。结果AG490可抑制JAK2／STAT3信号转导通路活化及结肠癌HT-29细胞侵袭，在此过程中AG490在mRNA水平抑制MMP-2表达。结论STAT3信号转导通路参与结肠癌细胞侵袭调控，阻断STAT3通路活化可抑制结肠癌细胞侵袭，这一作用可能是通过抑制MMP-2表达实现的。     

应用上唇外侧组织瓣旋转修复下唇缺损

目的:探求上唇外侧组织瓣在修复较大面积下唇缺损中的作用。方法:根据患者下唇缺损情况,设计上唇外侧组织瓣,旋转后插入缺损组织,同时在缺损吻合处,将上层外侧旋转瓣内侧粘膜肌肉向外牵拉形成部分新的红唇,然后逐层相对缝合,修复缺损。结果:自2003年1月应用此方法修复患者6例,术后随访1～2年,唇部外形好,无流涎,无口闭合不全,效果满意。     

2003年胶州市苯作业场所空气中苯的危害监测

近几年来随着青岛地区经济的发展,大量鞋革箱包及玩具制造,家具制造企业涌现于胶州.在这些企业里,普遍使用含有苯的强挥发性胶水粘合剂.苯系化合物已被WHO确定为强致癌性物质，由于苯系物属芳香烃类，无色透明易挥发，使人一时不易警觉其毒性。人在短时间内吸入高浓度的苯，会出现中枢神经麻醉的症状，轻者头晕、胸闷、恶心、乏力、呕吐。     

饮食控制及运动疗法对糖耐量降低人群干预效果分析

目的观察饮食控制及运动疗法对糖耐量降低人群血糖控制的影响。方法对门诊病例中符合1997年美国糖尿病协会诊断标准的60例糖耐量降低患者随机分为3组，分别采取饮食控制（饮食组）、运动疗法（运动组）及饮食控制＋运动疗法（饮食＋运动组）进行干预，8周后检测，对干预前后自身及各组间对照分析效果。结果3组干预后空腹血糖（FPG）和餐后2小时血糖（2hPG）均较干预前显著下降（P值分别〈0．05和0．01）。饮食＋运动组的总有效率显著优于饮食组和运动组（P值分别〈0．05和0．01），后两组间的差异无统计学意义（P〉0．05）。结论饮食控制与运动疗法有助于控制糖耐量降低人群的空腹及餐后血糖，有可能延缓其向糖尿病发展。
