130例国人正常胎儿手足长的测量

本文130例国人胎儿的手、足长测量结果表明:手、足长与胎龄线性相关(手∶r=0.9498;足∶r=0.963)。从而可据手或足长预测胎龄。结果还表明:左、右手长度无显著性差异(P<0.01)。     

Accidental ingestion of Ecstasy in a toddler.

Toddlers who ingest the drug of abuse 3,4-methylenedioxymethamphetamine (MDMA; 'Ecstasy') are at particularly high risk of serious neurological and cardiovascular side effects. We report of a 20-month-old male toddler who accidentally ingested Ecstasy. He presented with fever and seizures, tachycardia, hypertension, and hyperthermia. Urine amphetamine level was 2111 ng/mL. Treatment included rapid cooling, hydration, and support measures. Vital signs were regularly monitored. His condition became stable on day 2 and urine amphetamine level returned to normal on day 3 of hospitalization. His behavior, activity, and appetite had returned to their usual levels upon follow-up at our outpatient clinic. The incidence of drug abuse with MDMA has increased dramatically over the last decade in developed countries. It can be expected that accidental Ecstasy poisoning in children will increase as well. This case illustrates the need to consider the possibility of accidental Ecstasy ingestion in the differential diagnosis of a child suffering from convulsions with fever.     

血管性抑郁症的研究

目的 比较血管性抑郁症和非血管性抑郁症的临床特征和不同药物的治疗疗效.方法 采用自变量表分别对血管性抑郁症组和非血管性抑郁症组60例的发病年龄、起病形式、诱发因素、临床特征进行分析比较;并给予百忧解20 mg qm;30例血管性抑郁症患者联合血管活性药物及脑代谢剂,引用HAMD、MMSE与入院时、4周、8周进行评定,并逐一比较.结果 本研究显示血管性抑郁症患者发病年龄相对高,多数有诱因,睡眠障碍明显,焦虑躯体症状多,有较严重的阻滞及自杀倾向,合并一定认知功能障碍,对血管性抑郁症组中30例应用脑代谢剂,血管活性药物及抗抑郁剂,疗效明显优于血管性抑郁症组中单用抗抑郁药物,与非血管性抑郁症组相似.结论 血管性抑郁症采用血管性药物、脑代谢剂联合抗抑郁药物疗效明确,为临床治疗另辟新途径.     

Course of depressive symptoms and medication adherence after acute coronary syndromes: an electronic medication monitoring study.

OBJECTIVES: We tested whether improvements in depressive symptoms precede improved adherence to aspirin in patients with acute coronary syndromes (ACS). BACKGROUND: Depression is associated with medication nonadherence in patients with ACS, but it is unclear whether changes in depression impact on adherence. METHODS: Electronic medication monitoring was used to measure adherence to aspirin during a 3-month period in a consecutive cohort of 172 patients (25 to 85 years) recruited within 1 week of hospitalization for ACS. Depressive symptom severity was assessed using the Beck Depression Inventory (BDI) during hospitalization and at 1 and 3 months after hospitalization. Adherence was defined as the percentage of days aspirin was taken as prescribed. RESULTS: Depression severity in hospital was associated with nonadherence in a gradient fashion: 15% of non-depressed patients (BDI score 0 to 4), 29% of mildly depressed patients (BDI score 10 to 16), and 37% of patients with moderately-to-severely depressive symptoms (BDI score >16) took aspirin less than 80% of the time (p = 0.03). A cross-lagged path analytic model revealed that improvements in depressive symptoms in the first month after the ACS were associated with improvements in adherence rates in the subsequent 2 months (standardized direct effect -0.32, p = 0.016). CONCLUSIONS: Diagnosis and treatment of depressive symptoms may improve medication adherence in patients after ACS.     

第一极体不能精确定位人卵母细胞纺锤体

目的 观测人卵母细胞纺锤体的确切位置，从而指导今后的生殖医学临床工作。方法 应用纺锤体成像系统观测体外成熟及体内成熟组人卵母细胞纺锤体，测量卵子中心、纺锤体与第一极体之间形成的角度。比较两组结果的差异。结果 体外成熟组纺锤体与第一极体形成角度和体内成熟组存在显著差异(P=0．006)。结论 人卵母细胞的位置并不能准确定位卵母细胞纺锤体的位置。体外成熟组纺锤体与第一极体形成的角度要明显小于体内成熟组。应用纺锤体成像系统可以安全、有效地观察人卵母细胞纺锤体。     

中蒙医结合治疗胆囊切除术后综合征62例临床观察

目的：通过临床观察，探讨胆囊切除术后综合征的发生、发展及治疗效果。方法：通过对胆囊切除术后综合征的诱发因素、首发症状、ERCP诊断结果调查。探讨其发生发展规律以及中蒙医结合综合治疗的临床效果。结果：通过临床发现：①情绪不稳定引起本病主要诱发因素。②ERCP发现：胆管内残留结石，泥沙样结石的残留、残留胆囊结石、炎性梗阻为主要因素。结论：中蒙医结合治疗胆囊切除术后综合征疗效满意。     

成人先天性胆管扩张症手术治疗

目的 探讨成人先天性胆管扩张症手术治疗的经验体会。方法 回顾分析1985年1月至2004年12月中国医科大学附属第一医院普外科收治的成人先天胆管扩张症68例手术治疗资料。依Flanigan分型：Ⅰ型59例，Ⅱ型3例，Ⅳ型6例。所有病例均行囊肿切除，结果 术后发生胆汁漏6例。胰漏3例，急性胰腺炎2例。死亡2例，56例经1-20年随访，随访率为82．3％。5例表现轻度胆管炎，2例吻合口狭窄。余下49例均痊愈，无胆管炎及胆管狭窄表现。结论 囊肿切除、胆管空肠Roux-en-Y吻合是成人先天性胆管扩张症的首选治疗。切除囊肿时，囊肿近端在尽量切净囊肿基础上行大口吻合，防止术后吻合口狭窄；囊肿远端在保证睫液引流通畅、不损伤胰管开口的基础上，尽量切净囊肿内膜。     

胃泌素受体作为分子靶向在肿瘤中的表达及应用

胃泌素(Gas)广泛存在于胃肠道和胰腺组织内,在调控生理功能及某些疾病的发病机制中都有重要作用.近来研究表明,Gas能够促进肿瘤尤其是胃癌、大肠癌等消化系肿瘤的发生、发展.Gas的生物作用主要通过CCK受体介导,Gas mRNA在一些CCK受体阳性的小细胞肺癌,乳腺癌,卵巢癌,不同来源的癌干细胞,已经发现有表达,可能作为这些肿瘤自分泌生长调节的指示指标.对于过表达胃泌素受体的肿瘤,可以给予胃泌素多肽及类似物作放射性标记或连接细胞毒药物,体内用闪烁成像法跟踪显像,从而用于肿瘤的诊断和治疗.     

精索脂肪肉瘤（附6例报告）

目的探讨精索脂肪肉瘤的临床特点和诊治方法。方法回顾6例精索脂肪肉瘤临床资料，并复习有关文献。结果6例患者均行手术治疗，2例行肿瘤切除术，其余4例行根治术，术后随访19个月-11年，1例保留精索的年轻患者于术后3年出现局部复发，其余5例无复发及远处转移。结论精索脂肪肉瘤是一种低度恶性肿瘤，治疗方法主要以根治性手术为主，对于肿瘤高分化且年轻未育者，可行保留精索手术。     

A methoxylated fatty acid isolated from the brown seaweed Ishige okamurae inhibits bacterial phospholipase A2

A methoxylated fatty acid that inhibits phospholipase A(2) (PLA(2); EC 3.1.1.4) was purified from the brown seaweed Ishige okamurae. Approximately 8.1 mg of the inhibitory compound, 7-methoxy-9-methylhexadeca-4,8-dienoic acid, was isolated from 1 kg of I. okamurae powder. Recombinant PLA(2) derived from the pathogenic bacterium Vibrio mimicus was used as the target enzyme. The methoxylated fatty acid compound competitively inhibited PLA(2) with a Ki value of 3.9 microg/mL. The concentrations required for 50% inhibition of PLA(2), oedema and erythema were 1.0 microg/mL, 3.6 mg/mL and 4.6 mg/mL, respectively. The compound strongly inhibited PLA(2) activity in vitro and had potent antiinflammatory activity in vivo.
