目的 探讨社区老年高血压病人直立性低血压的药物影响。方法 通过对辖区内897例社区老年高血压病人开展体检,将年轻老年和老老年高血压两组分为直立性低血压组和非直立性低血压组两组。分析降压药物对社区老年高血压病人直立性低血压的影响。结果 OH组的降压药物使用率稍高于非OH组的降压药物使用率,经统计分析P>0.05。OH组联合两种以上及联合三种以上降压药物使用率略高于非OH的药物使用率, P>0.05。利尿剂OH发生率稍高于其他组的OH发生率,P>0.05。结论 社区老年高血压OH的发病可能与目前常用的5大类降压药物无关。

目的 探讨用捏脊联合中药外洗治疗脾胃气虚型儿童功能性消化不良的效果。方法 随机选取脾胃气虚型功能性消化不良的儿童120例,分为联合组、捏脊组、外洗组、对照组4个组,每组30例,分别采用捏脊、中药外洗、捏脊联合中药外洗、吗丁啉进行治疗,两周后观察4组治疗效果及唾液淀粉酶活性比值、D-木糖排泄率的变化,进行分析。结果 联合组的有效率优于捏脊组、外洗组、对照组,差异有统计学意义(P<0.05)。治疗后联合组的唾液淀粉酶活性比值比捏脊组、外洗组、对照组提高,差异有统计学意义(P<0.05)。治疗后D-木糖排泄率均较治疗前有增加,两两比较,联合组与对照组比较差异有统计学意义(P<0.05)。结论 捏脊联合中药外洗可改善脾胃气虚型儿童功能性消化不良,疗效良好,其机理同改善唾液淀粉酶活性有关。

目的 探讨磷酸二酯酶4抑制剂对人肺泡巨噬细胞(AM)吞噬非生物性颗粒及革兰阳性菌、阴性菌能力的影响。方法 使用Ficolll-Hypaque密度梯度法将外周血单核细胞分离的静脉血,在含有2 ng/m GM-CSF的培养液中经12天诱导培养成AM替代细胞模型—单核细胞源性巨噬细胞(MDM)。用酶标仪检测MDM经磷酸二酯酶4抑制剂Rolipram预处理过夜(16~18 h)后吞噬荧光标记的非生物颗粒Beads和热灭活的流感嗜血杆菌(H.influenzae)、金黄色葡萄球菌(S.aureus)量的改变,另使用MTT法检测细胞活性。结果 成功建立的MDM细胞模型对Beads和细菌的吞噬呈时效关。Rolipram在实验浓度(10^~8~10^-5 M)下对MDM吞噬Beads、H.influenzae和S.aureus能力无明显促进或抑制作用,也不影响MDM的活性。结论 磷酸二酯酶4抑制剂不会因升高巨噬细胞内cAMP水平而影响其吞噬非生物颗粒和细菌的能力。

Objective To investigate the influence of phosphodiesterases 4 inhibitor on the phagocytosis of non-biological particles and gram-positive bacteria, gram-negative bacteria by human alveolar macrophages. Methods Peripheral blood mononuclear cells (PBMCs) were isolated from venous blood from 12 healthy volunteers using Ficoll-Hypaque density gradients. Monocytes were incubated with media containing 2 ng/ml GM-CSF for 12d to allow full differentiation into macrophage (MDM), a functionally equivalent model of human AM. MDM were pretreated with Rolipram overnight (16-18h),phagocytosis of fluorescent labeled beads and H.influenzae,S.aureus by MDM was measured using a fluostar optima fluorimeter. Cell viability was assay with MTT. Results MDM phagocytosis of beads and bacteria was a time-dependant process. Rolipram in the concentration of 10^-8-10^-5M didn't inhibit or promote phagocytosis of beads and bacteria by MDM, and didn't affect the cell viability. Conclusion Phosphodiesterases 4 inhibitor would not affect the human macrophage phagocytic capacity of non-biological particles and bacteria associated with enhanced intracellular cAMP level.

目的 动态观察乳腺癌患者辅助内分泌治疗5年后的血脂及肝功能水平的变化,探求辅助内分泌治疗与高脂血症及脂肪肝发病率的关系。方法 56例乳腺癌患者实行辅助内分泌治疗,术后随访5年动态抽血测定其总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL)、高密度脂蛋白胆固醇(HDL)及谷草转氨酶(AST)、谷丙转氨酶(ALT)、直接胆红素(DBIL)、总胆红素(TBIL)等参数的变化,B超监测其肝脏变化。结果 经过2年内分泌治疗TG由(1.203±0.723)mmol/L上升至(1.701±1.271)mmol/L,5年内分泌治疗后TG降至(1.389±0.706)mmol/L。经过2年内分泌治疗LDL由(2.497±0.990)mmol/L上升至(2.950±0.984)mmol/L,5年内分泌治疗后LDL为(2.867±0.886)mmol/L。结论 辅助内分泌治疗2年会导致其TG和LDL的升高,5年随访仅发现LDL升高,辅助内分泌治疗会增加乳腺癌患者诱发心血管疾病的风险。

Objective To analyze the influence of respiratory rehabilitation treatment on BODE coring system of patients with chronic obstructive pulmonary disease (COPD) in stable phase in rural areas. Methods 60 patients with COPD in stable phase admitted into the hospital were selected as the research object and were randomly divided into control group and observation group with 30 cases in each. The control group received conventional treatment while the observation group received respiratory rehabilitation treatment. The changes of BOBE coring system in the two groups before and after the treatment were compared. Results After the treatment, BMI, FEV1% MMRC classification and 6MWD of the observation group were (22.4±1.1) kg/m², (68.6±3.6)%, (1.3±0.2) and (256.3±36.3) m respectively. The BODE index score decreased to (3.4±1.0), ADL (78.2±6.4), and QOL (67.8 + 2.6).compared with those of the control group, the difference was statistically significant (P< 0.05). And the decline level of inflammatory factors in the observation group was significantly higher than that of the control group (P<0.05). Conclusion In the clinical treatment of patients with COPD in stable phase in rural areas, respiratory rehabilitation treatment were adopted, the improvement of BOBE coring system indexes is significant. It is worthy to be popularized.
