Genome-wide scan identified QTLs underlying femoral neck cross-sectional geometry that are novel studied risk factors of osteoporosis.

A genome-wide screen was conducted using a large white sample to identify QTLs for FNCS geometry. We found significant linkage of FNCS parameters to 20q12 and Xq25, plus significant epistatic interactions and sex-specific QTLs influencing FNCS geometry variation. INTRODUCTION: Bone geometry, a highly heritable trait, is a critical component of bone strength that significantly determines osteoporotic fracture risk. Specifically, femoral neck cross-sectional (FNCS) geometry is significantly associated with hip fracture risk as well as genetic factors. However, genetic research in this respect is still in its infancy. MATERIALS AND METHODS: To identify the underlying genomic regions influencing FNCS variables, we performed a remarkably large-scale whole genome linkage scan involving 3998 individuals from 434 pedigrees for four FNCS geometry parameters, namely buckling ratio (BR), cross-sectional area (CSA), cortical thickness (CT), and section modulus (Z). The major statistical approach adopted is the variance component method implemented in SOLAR. RESULTS: Significant linkage evidence (threshold LOD = 3.72 after correction for tests of multiple phenotypes) was found in the regions of 20q12 and Xq25 for CT (LOD = 4.28 and 3.90, respectively). We also identified eight suggestive linkage signals (threshold LOD = 2.31 after correction for multiple tests) for the respective geometry traits. The above findings were supported by principal component linkage analysis. Of them, 20q12 was of particular interest because it was linked to multiple FNCS geometry traits and significantly interacted with five other genomic loci to influence CSA variation. The effects of 20q12 on FNCS geometry were present in both male and female subgroups. Subgroup analysis also revealed the presence of sex-specific quantitative trait loci (QTLs) for FNCS traits in the regions such as 2p14, 3q26, 7q21 and 15q21. CONCLUSIONS: Our findings laid a foundation for further replication and fine-mapping studies as well as for positional and functional candidate gene studies, aiming at eventually finding the causal genetic variants and hidden mechanisms concerning FNCS geometry variation and the associated hip fractures.     

多巴酚丁胺负荷超声心动图及组织多普勒成像技术在诊断冠心病中的临床应用

目的探讨多巴酚丁胺负荷超声心动图(DSE)和组织多普勒成像技术(TDI)在冠心病(CHD)诊断中的应用价值,以寻求一种敏感的、无创的CHD诊断方法。方法选择胸闷或胸痛怀疑CHD患者40例,应用TDI测量静息状态(Rest)下前壁中段收缩峰值速度(Vs),以及多巴酚丁胺峰值负荷状态(Peak)下前壁中段Vs,同时测量静息心率和负荷心率;所有入选对象均进行冠脉造影,并根据左前降支狭窄程度是否大于等于50%分为左前降支狭窄组(LST组)与左前降支非狭窄组(non-LST组)。分别比较Rest和Peak前壁中段LST组与non-LST组平均Vs差别等。结果Rest前壁中段LST组与non-LST组Vs差别无显著性意义;但Peak前壁中段LST组与non-LST组差别有显著性意义。结论DSE结合TDI是诊断冠心病有价值的定量分析方法。DSE在诊断CHD时的敏感性、准确性明显优于静息状态超声心动图。

COMPUTERIZED TOMOGRAPHY IN TUBERCULOUSMENINGITIS

This paper reports computerized tomography(CT) findings in 21 cases of tuberculous meningitis,normal in 5 and abnormal in 16. ' The cases withabnormal CT findings were hydrocephalus, tuber-culoma, exudation in basal cisterns, brain edema andcerebral infarction. The incidence of hydrocephalusincreased with the duration and severity of illness.The Iocations of tuberculomas corresponded withpatients' clinical pictures. The study also indicatedthat patients wih normal or slighly changed scanshad good prognosis, but patients with severe hydrocephalus and exudation m basal cisterns had poorprognosis in spite of active medical treatment. CThas been proved valuable in diagnosis and treatmentof tuberculous meningitis.     

Group coping skills training for anxiety and depression: its application with chronic patients

The literature on group coping skills training is reviewed and a model involving the use of a wide range of coping strategies with patients heterogeneous in terms of presenting problem is advocated. This study evaluates the effect of such an approach with a chronic inpatient and day-hospital patient population (n = 36) presenting with problems of anxiety and depression. Results suggest that the use of such groups can facilitate the transition from hospital to community. Further they are associated with symptomatic improvement that is of clinical significance in up to 50% of cases, which is largely maintained at 1 year follow-up and which is associated with a positive change in social functioning. In the light of this experience suggestions are made regarding the screening of patients and ways of enhancing group cohesion.
