183例老年人骨密度检测分析

目的 :研究老年人不同疾病时骨密度 (BMD)的分布情况。方法 :用DXADAS 6 0 0EX型骨密度仪对183例老年患者进行左侧远程桡骨加尺骨BMD检测。结果 :内分泌疾病组、消化道疾病组和其它疾病组的患病率分别为 72 7% ,2 0 6 %和 31 4 %。T值比较 :三组差异明显 (P <0 0 0 1)。累积骨丢失率 (ABLR)比较 :前一组明显高于后两组病人 (P <0 0 1)。BMD比较中 ,内分泌和其它疾病组明显低于消化道疾病组 (P <0 0 0 1)。相关分析显示 ,内分泌和消化道疾病组的年龄变化与BMD呈正相关 (r =0 5 19P <0 0 0 1和r =0 5 89P <0 0 0 1) ,内分泌疾病组和其它疾病组的体重变化与BMD呈正相关 (r=0 918P <0 0 0 1和r =0 338P <0 0 0 1)。结论 :老年人骨质疏松 (OP)患病率以内分泌疾病组最高 ,消化道疾病组较低 ;随年龄和体重增加 ,BMD降低加重。     

单能量X线测定骨密度的初步分析

目的：了解温州地区人群不同年龄组骨质疏松患病率及同年龄组男女骨质疏松患病的差异，强调早期预防治疗老年人及绝经期妇女骨质疏松的重要性，方法：应用单能量X线（SXA）骨密度仪测量246例正常人的右跟骨骨密度，结果：男性大于60岁组较小于60岁组骨密度（BMD）降低明显（P＜0．05）；女性50岁以上组与小于50岁组相比，BMD下降差异有极显性（P＜0．01）；各年龄组男女相比，男性BMD明显高于女性（P＜0．05）。结论：女性骨质疏松症的发病大多以绝经后为主，雌激素在维持骨量方面具有重要的作用。SXA检测的跟骨含95％小梁骨，能较好地确定骨质疏松的风险水平，且其具有价廉、简便，快捷，较准确等特点，故不失为一种较好的临床筛查手段。     

Clinical experience with the use of rhG‐CSF in secondary autoimmune neutropenia

This paper outlines the impact of granulocyte‐colony stimulating factor (G‐CSF) used as a single modality therapy in 17 patients with secondary autoimmune neutropenia (S‐AIN) who had been treated a multiple number of times previously. Fifteen of these patients had demonstrable antineutrophil antibodies and two had cellular S‐AIN with haemopoietic inhibitory T‐cells present in the marrow. Prior to treatment, all had had problems with infection. All patients responded within 7 days of commencement of treatment. Provided G‐CSF neutrophil counts were maintained above 1 × 10⁹/l, no further infections occurred. This was achievable by using G‐CSF administered as infrequently as once every 8 days. Eight of the 17 patients remained on G‐CSF, although five switched to the glycosylated form because of side‐effects. None have developed osteoporosis despite 47.29 patient years of total experience with G‐CSF. In conclusion both glycosylated and nonglycosylated G‐CSF can be used effectively in treating AIN on a long‐term basis.

维药无花果叶对抗大鼠泼尼松性骨质疏松的作用研究

目的：研究维药无花果叶醇提物对泼尼松致大鼠骨质疏松的对抗作用。方法：将50只大鼠随机分成正常对照组、泼尼松模型组和维药无花果叶醇提物高、中、低（10mg/kg、20mg/kg、30mg/kg）剂量组，每组10只。分别灌胃相应药物，每日1次，连续8周后取血清检测生化指标，对骨进行组织切片检查，长度、宽度以及骨质的测量。结果：泼尼松模型组大鼠股骨重量、尺骨羟脯氨酸和骨钙含量比正常对照组明显降低，胫骨骨髓腔中脂肪组织增多（P〈0．01），血浆胆固醇（TG）含量上升、碱性磷酸酶（ALP）和高密度脂蛋白（吼）含量下降（P〈0．01）。维药无花果叶醇提组能有效提高骨的重量和骨质的含量（P〈0．01），减少骨髓腔中脂肪的含量，升高碱性磷酸酶和高密度脂蛋白含量（P〈0．01）。结论：泼尼松可抑制大鼠的，肾生长及引起骨丢失，而维药无花果叶醇提物可有良好的对抗作用。

Diminished effect of etidronate in vitamin D deficient osteopenic postmenopausal women

Objective: The effects of vitamin D deficiency in osteopenic postmenopausal women treated with intermittent cyclical etidronate have been studied. Bone mass and biochemical parameters as bone markers were measured before and after one year of therapy with intermittent cyclical etidronate. Results: In 30 patients without vitamin D deficiency, bone mass in the lumbal spine and femoral neck was significantly increased compared to 28 vitamin D deficient patients. After cyclical intermittent etidronate therapy, serum osteocalcin and PTH were significantly increased in the vitamin D deficient patients, whereas in non-vitamin D deficient patients they did not change. Conclusion: It is worthwhile measuring serum vitamin D before starting etidronate therapy and, in case of deficiency, to give vitamin D.

Osteoporosis and Coronary Atherosclerosis in Asymptomatic Postmenopausal Women

Estrogen deficiency is a risk factor for osteoporosis and coronary artery disease. Osteoporosis can be evaluated by measuring bone mineral density (BMD). Coronary atherosclerotic burden can be evaluated by measuring coronary calcium using electron beam computed tomography (EBT) of the heart. We compared coronary calcium scores in 45 asymptomatic postmenopausal women with normal and low BMD. BMD of the lumbar spine and proximal femur was measured by dual X-ray absorptiometry (DXA), and coronary calcium was measured quantitatively by EBT. Women were divided into control, osteopenia, and osteoporosis groups based on the T score of the lumbar spine. Women were similar in age, years since menopause, height, weight, and body mass index (BMI). BMD ± SD (g/cm²) of L1–L4 was 0.96 ± 0.11, 0.83 ± 0.03, and 0.73 ± 0.05, in control, osteopenia, and osteoporosis group, respectively. The total coronary calcium score ± SD (relative units) was 41.9 ± 83.1, 115.1 ± 181.9, and 221.7 ± 355.4 for control, osteopenia, and osteoporosis group, respectively; the score was significantly higher in the osteoporosis than in the control group. This study provides initial data suggesting that women with osteoporosis may have a higher risk of developing coronary atherosclerosis.
