late leaf spot caused by Cercosporidium personatum is one of the most widespread groundnut leaf diseases. Along with early leaf spot and rust, it is one of the main fungal diseases hampering groundnut production worldwide. late leaf spot accounts for significant yield losses throughout the world where groundnuts are grown. This reduction in yield caused by the disease could result in yield losses of between 50% and 70%. In Burkina Faso, the disease is present throughout the country, with incidence varying according to region and season. Could the variability in the incidence of the disease be linked to the nature of the isolates or to the conditions from each agro-ecological zone? In this study, the aim was to assess the capacity of three isolates from three agroclimatic zones of the country to defoliate and reduce groundnut yield. To this end, three isolates of Cercosporidium personatum (Berk. Et M.A Curt.) were collected in these zones and evaluated on three contrasting groundnut varieties. A split-splot design was used for the experiment. Isolates were prepared from samples collected in farmers’ fields. After incubation in the laboratory, leaf spots showing good sporulation were scraped off with a scalpel after immersing the leaves in distilled water. Inoculations were carried out under controlled environment. After inoculation with the isolate, the percentage of defoliation and the reduction in yield of these varieties were then evaluated. Inoculation was carried out from the 30th day after sowing with Cercosporidium personatum spore suspensions at 105 spores/ml. The study showed that the percentage of defoliation (P = 0.0001) and the reduction in yield (P = 0.0001) were significant. The study revealed that, whatever the variety, isolate I3TF from the Upper Basins region in the South Sudanese zone caused the greatest defoliation and the greatest reduction in yield. The variety TS32-1, regardless of the isolate used for the treatment, recorded the best

背景：股骨转子下骨折的治疗具有复杂性。由于该部位具有较大的（肌肉）牵拉应力而使得近端骨折块较易移位以致于使骨折端的精确复位及内固定物放置困难。本研究的目的是评价一组高位股骨转子下骨折患者采取钳夹辅助复位及髓内钉内固定对于骨折愈合率及骨折复位质量的影响。方法：自2003年12月到2007年1月，来自于两个一级创伤中心共55例移位型高位股骨转子下骨折患者，其中2例死亡，9例失访。剩余44例患者均得到随访至术后6个月或至骨性愈合；男27例，女17例，平均年龄55岁。均采用扩髓型顺行静态锁定髓内钉内固定系统，同时通过外侧小切口使用钳夹辅助复位，其中9例患者加用线缆环扎骨折端。术后常规X线检查，评价骨折复位质量及骨折愈合情况。结果：随访44例患者中，43例患者达到骨性愈合，骨折复位后冠状面及矢状面成角均不大于5°。38例（86％）达到解剖复位，6例患者骨折端发生轻微的内翻畸形（2°-5°），所有的患者均无并发症发生。结论：使用钳夹辅助复位髓内钉固定适时加用线缆环扎骨折端治疗股骨转子下骨折可达到满意的骨折复位和较高的术后骨折愈合率。手术成功要点是操作细微，尽量减少对软组织的剥离。可信水平：治疗性研究Ⅳ级。关于证据等级的完整描述详见投稿须知。

Advances in Infectious Diseases 2013年第1期3卷 55-59页

The present study investigates the genetic diversity among Mycobacterium tuberculosis complex circulating in the Centre region of Cameroon and analyzes the relationship between genotypes and drug resistance patterns. Spoligotyping was performed by PCR-amplification followed by the reverse hybridization of 298 cultured specimens. Spoligotypes patterns were identified by comparison to reference strains in SPolDB4 database via the MIRU VNTR plus web application. About 97.65% of all tuberculosis (TB) cases were attributed to M. tuberculosis. A total of 65 different profiles were identified. Of these, 40 were represented as Shared Types (ST) while the others were orphans. lam10_CAM and Haarlem families were the most prevalent genetic families with 51.01% and 14.09% respectively. ST 61, a member of the lam10_ CAM family formed the largest cluster with 128 (42.95%) isolates. No association was found between genotypes with regard to drug resistance and HIV sero-status. However, there was a significant association between genotypes and age groups. Patients belonging to 15 - 24 and 35 - 44 age groups were more likely infected by lam10_CAM strains compared to others. The population structure of Mycobacterium tuberculosis complex strains from the Centre region was found to be diverse and the spoligotype 61 of the lam10_CAM family was highly predominant. Isolates of the lam10_CAM seem to be not associated with drug resistance.

Glycemic Responses of Food Formulations Based on White Rice and White Bean

The management of diabetes mellitus is based on lifestyle and dietary measures suggesting the consumption of foods with a low glycemic index. The present study was conducted in order to propose food formulas based on white rice and white beans resulting in a lower glycemic response. For this, food formulations based on these foods were first made, in particular the formulation [75% white rice + 25% white beans] and the formulation [50% rice + 50% white beans]. Then, the biochemical composition of white rice, white bean and these two formulations was determined by the usual methods. Finally, their glycemic responses over 120 minutes were studied by the FAO/ WHO 1998 method. The results showed that white rice [100% white rice] had the highest carbohydrate content (54.61%) followed respectively by the formulation [75% white rice + 25% white bean] (45.69%), the white bean [100% white bean] (29.1%) and the formulation [50% white rice + 50% white bean] (26.16%). In terms of glycemic responses, the formulation [50% white rice + 50% white beans] presented the best evolution with a lower peak (6.041 mmol/l) observed at T45min and a lower postprandial glycemia (4.872 mmol/ l) at T120min. An increase in the proportion of beans is therefore recommended as it may suggest a beneficial metabolic effect.

有色可溶性有机物(CDOM)是指水体中对紫外及可见光均有光吸收的溶解有机物,能对水色产生影响,是自然生态系统、水色光学遥感、水体碳循环研究中必不可少的环境因素。由于CDOM具有荧光特性,荧光光谱技术已成为开展CDOM研究的重要手段,被用于CDOM的来源、分布及其变化规律的研究。文章主要利用荧光检测技术,研究了不同水体CDOM的发射荧光光谱峰面积、荧光峰强度与其浓度间的变化关系,发现在低浓度范围内,发射光谱峰面积和荧光强度与CDOM浓度具有良好的线性关系(r2>0.98);不同浓度的CDOM水溶液的发射光谱峰面积及其荧光强度随浓度的变化趋势是一致的。文章首次利用低浓度下CDOM的发射光谱峰面积与浓度间的线性关系,建立了适合于水体中组成复杂的CDOM的定量分析方法,拓展了荧光分析技术在CDOM研究中的应用。
