祖国传统医学对骨质疏松症的治疗进展

骨质疏松症是以骨量减少和骨组织的纤维结构退化为特征的代谢性骨病。随着21世纪我国老龄化社会的到来，骨质疏松发病率明显增高，已逐渐成为世界性广泛关注的问题。原发性骨质疏松分为I、Ⅱ两种类型。I型为高代谢型，主要是绝经后骨质疏松，由雌激素缺乏，而使骨代谢呈负平衡，骨吸收相对增强引起；Ⅱ型是低骨转换型，主要为老年性骨

原发性肝癌患者肝切除术前、后免疫细胞表型分析

目的研究原发性肝癌(PrimaryLiverCarcinoma,PLC)患者肝切除术前、后免疫细胞表型的变化。方法采用直接免疫荧光标记,流量血细胞计数法(FlowCytometry,FCM)检测方法,动态观察120例PLC患者肝切除术前后外周血T淋巴细胞亚群、NK细胞和HLA鄄DR含量变化。结果肝切除术前肝功能Child鄄PughB级、OGTTL型和术前施行肝动脉栓塞化疗患者外周血CD8+T细胞含量明显低于正常人组,CD4+/CD8+比值则较高(P<0郾05)。全部肝癌患者肝切除术前、后CD3+CD4+T细胞和NK细胞(CD3-CD16+CD56+)含量无明显差异。术后第1天、第3天、第7天和第2周外周血淋巴细胞CD3+CD8+含量明显低于肝切除术前和术后第3周(P<0.01);而CD4+/CD8+比值则显著高于肝切除术前和术后第3周(P<0郾01)。结论PLC合并肝硬变肝储备功能不足、术前肝动脉栓塞化疗和肝切除术可导致机体细胞免疫功能低下,PLC患者肝切除术前行肝动脉栓塞化疗的价值有待深入研究。     

Prevalent vertebral deformities predict increased mortality and increased fracture rate in both men and women: A 10-year population-based study of 598 individuals from the Swedish cohort in the European Vertebral Osteoporosis Study

The aim of this study was to evaluate whether a prevalent vertebral deformity predicts mortality and fractures in both men and women. In the city of Malmö, 598 individuals (298 men, 300 women; age 50–80 years) were selected from the city's population and were included in the Swedish part of the European Vertebral Osteoporosis Study (EVOS). At baseline the participants answered a questionnaire and lateral spine radiographs were performed. The prevalence of subjects with vertebral deformity was assessed using a morphometric method. The mortality during a 10-year follow-up period was determined through the register of the National Swedish Board of Health and Welfare. Eighty-five men and 43 women died during the study period. The subsequent fracture incidence during the follow-up period was ascertained by postal questionnaires, telephone interviews and by a survey of the archives of the Department of Radiology in the city hospital. Thirty-seven men and 69 women sustained a fracture during the study period. Data are presented as hazard ratios (HR) with 95% confidence interval (95% CI) within brackets. Prevalent vertebral deformity, defined as a reduction by more than 3 standard deviations (SD) in vertebral height ratio, predicted mortality during the forthcoming decade in both men [age-adjusted HR 2.4 (95% CI 1.6–3.9)] and women [age-adjusted HR 2.3 (95% CI 1.3–4.3)]. In men there was an increased mortality due to cardiovascular and pulmonary diseases and in women due to cancer. Prevalent vertebral deformity predicted an increased risk of any fracture during the forthcoming decade in both men [age-adjusted HR 2.7 (95% CI 1.4–5.3)] and women [age-adjusted HR 1.8 (95% CI 1.1–2.9)]. Prevalent vertebral deformity predicted an increased risk of any subsequent fragility fracture in women [age-adjusted HR 2.0 (95% CI 1.1–3.5)]; however, in men the increased risk was nonsignificant [age-adjusted HR 1.9 (95% CI 0.7–5.1)]. In summary, a prevalent vertebral deformity can predict both increased mortality and increased fracture incidence during the following decade in both men and women. We conclude that prevalent vertebral deformity could be used as a risk factor in both genders for mortality and future fracture.     

骨钙素酶免疫检测方法的研究和应用

目的：建立骨钙素酶免疫测定方法，并应用于临床检测血清骨钙素。方法：应用了3种检测模式，根据检测灵敏度、剂量反应曲线的形态进行分析，选择出合适的模式进一步应用于临床血清标本的骨钙素检测。结果：所采用的骨钙素单克隆抗体是钙离子依赖型的。固相抗原竞争法适合于临床定量测定骨钙素。最低可测限为1．4μg/L;20μg/L骨钙素样品批内CV＝3．98％，批间CV＝12．67％。测定正常献血员140名（年龄17－45岁），第5－95百分位点的骨钙素含量，男性为7．5－15．0μg/L女性为7.0-17.5μg/L。70例疑有骨质疏松症患者血清骨钙素含量2．91－30．20μg/L，以第95百分位点的骨钙素含量为cut-off值，升高5例。与进口试剂盒（Novocalcin,USA）相比较，有较好的相关性，r=0.81。结论：固相抗原竞争法酶免疫测定可以灵敏地检测血清中骨钙素含量，有实用价值。     

Treatment of osteoporosis in men

Osteoporosis in men is recognised worldwide as an important and increasing public health problem. The causes are more heterogeneous than those in women. About 50% are diagnosed as secondary cases. In some secondary forms of osteoporosis the specific diagnosis results in additional therapeutic options (e.g. androgen therapy in proven hypogonadism). The basic therapy for osteoporosis in men is no different to that in postmenopausal women, namely recommendations for counteracting modifiable risk factors, especially with regard to diet, physical exercise, and calcium and vitamin D supplementation. Concerning specific drug medications, however, even today there is still a therapeutic dilemma in male osteoporosis. While older substances (e.g. calcitonin, fluoride, alfacalcidol) are approved for both sexes, all newer medications have primarily been approved for the treatment of postmenopausal osteoporosis. Health authorities request studies in purely male populations. For new drugs, fracture data are necessary while for new substances within a class (e.g. bisphosphonates), at the very least consistent effects on bone mineral density (BMD) and bone turnover markers are requested. Due to these regulatory rules, ibandronate, teriparatide and strontium ranelate are not approved in the European Union. Some years ago, alendronate was the first bisphosphonate that was approved for the treatment of men with osteoporosis, based on consistent results from two independent male studies using a daily 10 mg dosage. Very recently risedronate was approved by the FDA and EMEA. A randomised, placebo-controlled multicentre trial of 285 male patients showed, after 2 years, a 5.8% increase in lumbar spine BMD in the risedronate 35 mg once weekly group vs 1.2% in the placebo group. In a prospective controlled study on 316 men with primary or secondary osteoporosis we found, after 12 months, a lumbar spine BMD of +4.7% vs +1.0% in controls. The number of patients with one or more new vertebral fractures was 8 in the risedronate group and 20 in the placebo group (a fracture reduction of 60%). Furthermore, we found a significantly smaller decrease in height and a steeper decrease in back pain in the risedronate group. Risedronate is the first oral bisphosphonate available for men with the more comfortable once weekly dosage.

血清痩素对老年男性骨质疏松的影响

目的 探讨血清瘦素水平对老年男性骨质疏松的影响。方法 选取年龄在60-92岁的158例老年男性，采用双能X线法（DXA）检测骨密度，并根据测值将受试者分为骨质疏松组与非骨质疏松组，用放射免疫法（RIA）检测两组空腹血清瘦素浓度，进行比较研究。结果 血清瘦素测值在不同年龄组间的差异无统计学意义，而在肥胖组与非肥胖组间有显著差异（P〈0．01）。在老年男性骨质疏松组血清瘦素测值明显低于非骨质疏松组，两者具有显著差异（P〈0．05）。结论 血清瘦索测值并不随老年男性的年龄而变化。但与老年男性的体重指数呈正相关，血清瘦素对老年男性骨质疏松有较好的预示及保护作用。
