Local inflammatory response in choriodecidua induced by Ureaplasma urealyticum

Ureaplasma urealyticum is the bacterial species most often connected with preterm birth, although it often colonises the amniotic fluid without any adverse effects. The induction of preterm labour seems to depend on whether the bacteria produce an inflammatory reaction. In vitro stimulation of choriodecidual tissue with high amounts of U. urealyticum or with lipopolysaccharide induced a qualitatively similar inflammatory response detected by the production of tumour necrosis factor alpha, followed by secretion of anti-inflammatory cytokine interleukin-10 and of prostaglandin E₂. Lower quantities of bacteria failed to induce any response.     

5种真空采血促凝管在生化检验中的应用及评价

目的 评价五种真空采血促凝管对常规生化检测项目的影响。方法 采集健康体检者及自愿者血液标本100例,选用5个不同厂家生产的真空采血促凝管,与美国BD公司生产的无添加剂的血清管进行采血质量和生化检测对比评价。结果 5个厂家生产的真空采血促凝管与BD公司生产的无添加剂血清管在多数生化检验项目上无明显差异(P>O.05),但有3个国内厂家生产的真空采血促凝管在标本采集质量、分离效果上存在明显不足,且在血清K、LDH、HBD、CK、CHOL、TG、HDL-c、LDL-c、APOA、APOB等检测上与对照组间存在着显著差异(P<0.05且r相似文献   

肾动脉狭窄介入治疗前后血清脑利钠肽水平的变化及意义的研究

目的探讨肾动脉狭窄介入治疗前后血清脑利钠肽BNP水平的变化及意义。方法采用回顾性调查方法，对肾动脉狭窄介入治疗前后血清脑利钠肽水平的变化进行分析。结果肾动脉狭窄介入治疗再通后，血清BNP水平出现下降（P〈0．01）。结论血清BNP水平的变化对肾动脉狭窄介入治疗后疗效的评价具有一定的临床指导意义。     

Insulin secretion and glucose tolerance in non-insulin dependent diabetic patients after chronic nifedipine treatment

Summary The effect of nifedipine 40 mg·day^–1 for 3 months on glucose tolerance, insulin and C-peptide secretion after an oral glucose tolerance test (OGTT), intra-venous glucose tolerance test (IVGTT) and glucagon stimulatory test, has been studied in 8 moderately hypertensive women suffering from non-insulin dependent diabetes mellitus (NIDDM).No significant variation in glucose metabolism was noted after nifedipine treatment, except for a slight improvement in insulin secretion after OGTT at the end of the study. There was an increase in cholesterol as a collateral effect.     

温阳活血方防治急性冠脉综合征临床研究

目的研究温阳活血法对急性冠脉综合征患者临床症状、炎症反应、纤溶系统及血管内皮细胞功能等相关指标的影响。方法将急性冠脉综合征患者80例随机分为治疗组和对照组（各40例）,2组均给予西药常规扩冠、降脂、抗血小板聚集等治疗,治疗组加用温阳活血方,观察患者治疗前后中医证候、心绞痛疗效及血栓素B2（TXB2）、6-酮-前列腺素（6-K-PGF）、组织纤溶酶原激活物（tPA）、白细胞介素-2（IL-2）、白细胞介素-6（IL-6）、纤溶酶原激活物抑制物（PAI）等指标变化。结果治疗组与对照组心绞痛总有效率分别为80%、65%（P〈0.05）;治疗组及对照组中医证候总有效率分别为82.5%、62.5%（P〈0.05）;治疗组治疗后6-K-PGF、tPA等显著升高（P〈0.05,P〈0.05）;IL-6、IL-2、PAI、TXB2等均显著降低（P〈0.05或P〈0.01）。结论对急性冠脉综合征患者应用温阳活血方治疗可明显改善临床症状、调节纤溶系统及血管内皮细胞功能、降低炎症反应。

Disappointing results and low tolerability of photodynamic therapy with topical 5-aminolaevulinic acid in psoriasis. A randomized, double-blind phase I/II study

BACKGROUND: Based on good results in the treatment of superficial skin tumours, since the early 1990s topical photodynamic therapy with aminolaevulinic acid (ALA PDT) has been used for disseminated, inflammatory dermatoses including psoriasis. However, there is still a lack of well-documented trials. OBJECTIVE: A prospective randomized, double-blind phase I/II intrapatient comparison study was conducted in 12 patients to investigate whether topical ALA PDT is an effective treatment for chronic plaque-type psoriasis. METHODS: In each patient three psoriatic plaques were randomly treated with a light dose of 20 J/cm(2) and 0.1%, 1% and 5% ALA, respectively. Treatment was conducted twice a week until complete clearance or for a maximum of 12 irradiations. Therapeutic efficacy was assessed by weekly determination of the psoriasis severity index (PSI). RESULTS: The mean percentage improvement was 37.5%, 45.6% and 51.2% in the 0.1%, 1% and 5% ALA-treated groups, respectively. Irradiation had to be interrupted several times because of severe burning and pain sensation. CONCLUSION: Topical ALA PDT did not prove to be an appropriate treatment option for plaque-type psoriasis due to disappointing clinical efficacy, the time-consuming treatment procedure and its unfavourable adverse event profile.
