Epidemiological survey of Angiostrongylus cantonensis in the west-central region of Guangdong Province, China

The study was to understand the Angiostrongylus cantonensis infectious situation of rodent definitive host, snail intermediate host, and local residents in the west-central region of Guangdong Province in China. The snails Achatina fulica and Pomacea canaliculata collected from the survey place were digested with artificial gastric juice, and the third-stage larvae of A. cantonensis in the snails were examined under microscope. The heart and lung of rats captured from the survey place were taken to check the adult of A. cantonensis. The questionnaire surveys related to the infection of A. cantonensis were taken in local residents randomly selected, and the IgG antibody against A. cantonensis was tested in those residents with enzyme-linked immunosorbent assay (ELISA). A total of 1,391 rats including eight kinds of rats, such as Rattus norvegicus, Rattus flavipectus, Bandicota indica, Rattus sladeni, Mus musculus, Rattus rattoides, Suncus Murinus, and Rattus confucianus, were examined and 132 of them were infected by A. cantonensis, with an average infection rate of 9.49% and a mean intensity of A. cantonensis in infected rats was 9.39. A total of 3,184 snails A. fulica and 3,723 snails P. canaliculata were detected. The average infection rates of them were 25.03% (797/3,184) and 6.50% (242/3,723), respectively. There were 180 positive samples of IgG antibody against A. cantonensis in 1,800 serum samples of the residents, with a positive rate of 10.00%. The west-central region of Guangdong Province is the natural focus of A. cantonensis. In comparison with the investigation results in other regions of China, the infection rate of rat definitive host is at the middle level; in the intermediate host, the infection rate of snail A. fulica is above the middle level, and the infection rate of snail Pomacea canaliculata is below the middle level. Some local residents had already been infected by A. cantonensis or at the risk of being infected.

国产降纤酶治疗脑梗死研究

目的　为进一步研究国产降纤酶对脑梗死的疗效。方法　采取随机双盲对照临床研究。在应用降纤酶治疗前及用药后第 14d分别进行神经功能缺损评分 (NDF) ,并进行日常生活能力评估 (Barthel指数 )。同时检测血浆中纤维蛋白原含量、肝功和肾功。结果　降纤酶治疗组血浆纤维蛋白原含量在用药后极显著降低 (P <0 0 1)对肝功、肾功、凝血功能无影响 ,也未发生过敏反应。近期疗效降纤酶治疗组显著优于对照组。神经功能缺损评分及Barthel指数有显著进步 (P <0 0 5 )。结论　国产降纤酶为安全有效地降低血浆纤维蛋白原含量及治疗急性脑梗死有较好疗效的药物

康莱特注射液联合EP方案治疗小细胞肺癌的疗效及不良反应比较

目的：探讨EP方案与康莱特配合EP方案治疗小细胞肺癌的疗效和不良反应。方法：对照组（A组）为21例患者接受EP方案化疗1周期以上;VP-16100mg/m2静脉滴注,d1-3天,DDP25mg/m2静脉滴注,d1-3天。治疗组（B组）为23例患者接受康莱特配合EP方案化疗：EP方案同A组,康莱特100ml静脉滴注,每天2次,d4-24,化疗结束后28-30天评价疗效和不良反应。结果：对照组有效率为42.8%,2例出现3度消化道反应（WHO标准）,2例出现3度血液反应,1例出现4度血液反应,卡氏评分提高率19.04%。治疗组有效率为43.4%,1例出现3度消化道反应,1例出现3度血液反应,卡氏评分提高率60.8%。结论：对于小细胞肺癌,EP方案与康莱特配合EP方案治疗小细胞肺癌的疗效统计学无明显差异,但康莱特配合EP方案能明显减轻化疗反应,改善生活质量。     

Development of splenic surgery in China

Splenic surgery has enjoyed rapid progress for the past decades in China. Based on continuously solidifying theories and clinical practice, many advanced concepts with applicable clinical frameworks have been established, thus making splenic surgery an indispensable division in modern surgery. In this study, the authors try to give an overview of the developments in this field. Spleen function is a key issue that generally guides advances in splenic surgery. The old knowledge of the dispensable spleen  has been abandoned, while the exact role that it plays in the body continues to be unveiled. Now, standard grading for splenic injury and the respective guidelines for clinical management have been established, with the use of selective instead of indiscriminate splenectomy being accepted by most experts. Various spleen sparing operations have been developed, while many advanced techniques such as laparoscopy have been introduced to splenic surgery. Spleen transplantation has greatly advanced in China, even though there are still many unsolved mysteries in this field. Altogether, splenic surgery is a new and prosperous discipline, and it is a tremendous stage for young surgeons to be part of.

Effect of arotinolol on right ventricular function in patients with dilated cardiomyopathy

Objective Dilated cardiomyopathy (DCM) is generally considered to be accompanied by both left and right ventricular dysfunction,but most studies only analyze the left ventricular function. In this study, we evaluated the effect of arotinolol on right ventricular function in patients with DCM. Methods Right ventricular ejection fraction (RVEF) and right ventricular diameter (RVD) were measured by two-dimensional echocardiography (2-DE) in 33 DCM patients; RVEF measured by first-pass radionuclide angiography (FPRA) was compared with that by 2-DE. Results The treatment with arotinolol for one year resulted in a reduction in the right ventricular diameter (baseline, 23.0 ± 8.3 mm vs after one-year treatment, 20.7 ± 5.4 mm; P=0.004 ) and an associated increase in ejection fraction (baseline, 36.9 ± 10.3% vs after one-year treatment, 45.8 ± 9.6%; P ＜ 0.001 ); there is a high correlation between the 2-DE method and radionuclide ventriculographic method. The correlation coefficient is 0.933 (P＜0.001). Conclusion Arotinolol therapy could not only improve left ventricular function, but also improve right ventricular function in DCM patients.
