The first record of <Emphasis Type="Italic">Spirocerca lupi</Emphasis> (Rudolphi, 1809) (Spirocercidae,Nematoda) from Poland based on faecal analysis of wolf (<Emphasis Type="Italic">Canis lupus</Emphasis> L.)

Summary During studies on the helminth fauna of wolves inhabiting natural ecosystems of Poland, 86 scats were examined. All the samples were collected in the autumn of 2005. Spirocerca lupi was detected with decantation and flotation techniques. The prevalence was 2.32 %. This is the first record of the parasite from Poland and the third case of its occurrence in the wolf (Canis lupus L.) within its distribution range.     

Anatomical considerations of selective pudendal neurectomy

The pudendal nerve was examined in 100 cadavers of both sexes. Because of the variable number of trunks of the pudendal nerve, 5 types were distinguished: one-trunked; two-trunked, rectopudendal; two-trunked, pudendo-penile (or-clitoridal); three-trunked, recto-perineo-penile (or-clitoridal); four-trunked, recto-perineo-perineopenile (or-clitoridal). The authors' suggestions make it possible to perform selective pudendectomy, consisting in denervation of the sphincter urethrae muscle by neurectomy of the perineal branches of the pudendal nerve.     

局部麻醉和硬膜外麻醉下行无张力腹股沟疝修补术对老年病人的影响

[目的]比较局部麻醉和硬膜外麻醉下行无张力腹股沟疝修补术对老年病人的影响。[方法]将133例同期手术老年病人用抽签法随机分为局部神经阻滞麻醉组（观察组）和硬膜外浸润麻醉组（对照组），观察两组病人术中及术后血压、心率、平均手术时间、术后首次自排小便时间、住院时间、手术并发症等。[结果]观察组病人术后生活自理时间、术后首次自排小便时间、手术及麻醉时间、住院天数均少于对照组。[结论]老年病人局部麻醉下行无张力腹股沟疝修补术比硬膜外麻醉术痛苦少、恢复快、住院时间短。     

腹茧症合并不孕七例临床分析

目的探讨腹茧症合并不孕的病因和诊治方法。方法对1996年至2005年因不孕施行腹部手术中发现的7例腹茧症患者进行回顾性分析。结果7例患者均为原发、管性不孕。其共同特点为,术中见多重疏松、灰白色的纤维膜状组织包裹于肠管间隙及盆腔脏器,手术分离困难。结论腹茧症引起的不孕可能为纤维膜包裹输卵管,使其丧失活动度,伞端封闭,无法完成捡拾和输送卵子的功能或包裹卵巢,使其排卵障碍而不能受孕。术后"假性囊肿"或"包裹性积液"易复发。     

多站点综合性毕业考试的改革与实践

我校改革临床医学专业毕业考试模式与方法，在临床实习过程中组织多站点综合性考试，采用闭卷笔试方法考核临床理论知识，占70％；采用实践操作与现场口试方法考核临床技能及相关知识，占20％；采用开卷笔试方法考核医疗文书书写，占10％。实践证明，此项改革能促进医学生端正实习态度，调动实习的积极性与主动性，引导医学生在实习中重视理论学习与临床实践的密切结合，促进临床教学质量的提高。     

The characteristics of Hep-2 cell with multiple drug resistance induced by Taxol.

OBJECTIVE: To investigate the characteristics of Hep-2 cell with multidrug resistance (MDR) induced by Taxol. STUDY DESIGN: Hep-2 cells were exposed in stepwise escalating concentration of Taxol to develop the resistant cell line-Hep-2T. Cell cycle distribution, apoptosis, and rhodamine accumulation were studied through flow cytometry. The MDR1 and MRP1 genes were detected through real-time quantitative RT-PCR, and the corresponding proteins were detected through Western blotting. RESULTS: The drug resistance of Hep-2T cells to Taxol, doxorubicin, gemcitabine, 5-FU, and cisplatin all increased. The percentage of G0/G1 phase and the antiapoptosis ability increased significantly compared with Hep-2 cells. Both MDR1 and MRP1 also increased at gene and protein level, though MDR1 was more prominent. CONCLUSION: More emphasis should be laid on MDR1/Pgp, the non-Pgp substrate chemotherapeutic agents, and the changes of cell cycle distribution to prevent MDR induced by Taxol. SIGNIFICANCE: These findings may provide theoretical support for the reverse of MDR.     

修饰电极技术在维生素K_1含量测定中的应用

日的:寻找一种测定溶液中维生素K,含量的新方法、方法:由修饰玻碳电极为工作电极的三电极体系,用锁相交流溶出伏安法进行测定。结果:峰电流(ip)与维生素K1的浓度(c)在7.21 X 10-7g/ml～8.11×l0-6 g/ml范围内呈现良好的线性关系,检出限为7.8×10-8g/ml。结论:该方法与其它方法相比,简便、快捷,结果令人满意     

间接血凝法检测抗Sm抗体和抗RNP抗体

应用间接血凝法测定抗Ｓｍ抗体和抗ＲＮＰ抗体。对不同疾病的检测结果表明，建立的该种方法与免疫电泳法结果无显著性差异（Ｐ＞０．０５）。对ＳＬＥ病４５例检测抗Ｓｍ抗体阳性率为１００％，抗ＲＮＰ抗体阳性率为９１％，抗Ｓｍ抗体可作为ＳＬＥ的特异性标志抗体，抗ＲＮＰ抗体在ＲＡ、ＰＳＳ、ＤＭ、ＭＣＴＤ病人中检出，其中ＭＣＴＤ病２３例，抗ＲＮＰ抗体阳性率高达９６％。且凝集效价高，可作为此病诊断的重要依据。间接血凝法具有操作简便、快速、敏感、特异性高、便于推广等特点，可代替免疫电泳法。     

Risk factors for wheezing in Ukrainian children: Ukraine European Longitudinal Study of Pregnancy and Childhood Group

The prevalence of wheezing in children varies widely around the world. The reasons for this geographic variability remain unclear but may be related in part to exposures in the home environment during pregnancy and early childhood. We investigated the prenatal and early childhood risk factors for wheezing symptoms among 2127 children aged 6–8 years who were participants in the Ukrainian component of the European Longitudinal Study of Pregnancy and Childhood (ELSPAC). Cases included the 169 children whose parents answered yes to the International Study of Asthma and Allergy in Children (ISAAC) question: 'Has your child had wheezing or whistling in the chest in the past 12 months' during the ELSPAC assessment of the children at age 7. These were compared with the 1861 children in the cohort whose parents answered 'no' to this question.
Factors significantly associated with increased risk of wheezing illness at age 7 in adjusted analyses included mother's asthma [adjusted odds ratio (OR) 3.46, 95% confidence interval (CI) 1.22, 9.85]; mother's allergy problems (OR 1.43, [1.00, 2.05]); rarely playing with other children at age 3 (OR 1.84, [1.09, 3.11]); water intrusion (OR 1.62, [1.09, 2.39]) and inadequate heating of the home (OR 1.52, [1.06, 2.16]) during pregnancy. Factors protective of wheezing at age 7 included being first-born (adjusted OR 0.70, 95% CI 0.50, 0.98); living in the city of Dniprodzerzynsk as compared with Kyiv (OR 0.36, [0.24, 0.54]) and weekly contact with furry animals (OR 0.44, [0.20, 0.97]) before age 3. The constellation of risk factors for wheezing in Ukrainian children is similar to that of children in other parts of the world. Known risk factors do not account for the significant between-city variability of wheezing in Ukrainian children.
