目的 探讨压力管理对改善中年高血压患者生活质量的效果。方法 采用便利抽样法,把首次在我院住院的中年高血压患者115例按时间段分为实验组60例和对照组55例,对照组给予常规护理,实验组采用压力管理干预,分住院期和出院后康复期两阶段进行。使用抑郁自评量表和SF-36量表分别在出院前和出院后1个月进行测评。结果 干预后实验组患者抑郁标准分降低,SF-36量表各维度分及总分升高,与对照组比较差异均有统计学意义(P＜0.05)。结论 对中年高血压患者实施有针对性、整体性、延续性和激励性的压力管理,可提高其生活质量。

Objective To explore the influence of stress management on the improvement of quality of life of middle-aged patients with hypertension. Methods According to convenience sampling, 115 middle-aged patients with hypertension who were the first time admitted to our hospital were divided, on the basis of different periods, into the test group (60 patients) and the control group (55 patients). The control group was accepted normal nursing, while the test group was accepted the stress management intervention that performed during hospitalization and after patients discharged from the hospital. Both groups were assessed, by using self-rating depression scale and SF-36 scale, before discharging from hospital and one month after discharging from hospital. Results After the intervention, the test group experienced reductions in depression standard score and increases in dimension scores and total scores of SF-36 scale.compared with those of the control group, these changes had statistical significant (P＜0.05). Conclusion Selective, integrated, continuous and stimulating stress management can help middle-aged patients with hypertension to improve the quality of life.

       目的  探讨晚期早产儿中小于胎龄儿（SGA）与适于胎龄儿（AGA）出生时的铁代谢状态。方法  选取2020年1—12月合肥市妇幼保健院收治的150例晚期早产儿（胎龄34～36⁺⁶周）作为研究对象。按照出生体质量和胎龄将早产儿分为SGA组（36例）和AGA组（114例），分析比较两组早产儿出生时的铁代谢状态，并应用多因素线性回归分析血清铁的影响因素。结果  与AGA组相比，SGA婴儿的更低的血清铁［14.5 μmol /L （11.4，17.1） vs 16.4 μmol /L（14.1，18.4），P=0.004］、更低的血清铁蛋白［135.6 μg/L（101.8，176.2） vs 172.5 μg/L（123.0，218.3），P=0.009］和更低的总铁结合力［30.4 μmol/L（26.8，34.9）vs 35.4 μmol/L（29.5，44.6），P=0.001］。两组早产儿的血红蛋白、平均红细胞体积、平均红细胞血红蛋白含量和平均红细胞血红蛋白浓度比较差异均无统计学意义（P＞0.05）。在早产儿围生期特征中，胎盘异常（β= –1.949，P=0.009）和母亲糖尿病的发生（β= –2.324，P=0.001）与血清铁水平呈负相关。结论  与早产AGA相比，早产SGA铁储备水平较低，适量补充铁元素对小于胎龄新生儿身体发育有促进作用。

      Objective   To explore the iron metabolism status in late preterm infants who are small for gestational age（SGA）compared to those appropriate for gestational age（AGA）at birth．Methods   A total of 150 late preterm infants（gestational age 34 to 36⁺⁶ weeks）admitted to the Maternal and Child Health Hospital of Hefei from January to December 2020 were selected as the study subjects．The preterm infants were divided into the SGA group（36 cases）and the AGA group（114 cases）according to birth weight and gestational age．The iron metabolism status at birth was analyzed and compared between the two groups of preterm infants，and multiple linear regression analysis was applied to identify the influencing factors of serum iron．Results   Compared with the AGA group，SGA infants had lower serum iron（14.5［11.4，17.1］ vs 16.4 ［14.1，18.4］，P=0.004），lower serum iron protein（135.6［101.8，176.2］ vs 172.5［123.0，218.3］，P=0.009），and lower total iron binding capacity（30.4［26.8，34.9］ vs35.4［29.5，44.6］P=0.001）．There were no statistically significant differences in hemoglobin，mean corpuscular volume，mean corpuscular hemoglobin，and mean corpuscular hemoglobin concentration between the two groups of preterm infants（P＞0.05）．Among the perinatal characteristics of preterm infants，placental abnormalities（β= –1.949，P=0.009）and the occurrence of maternal diabetes（β= –2.324，P=0.001）were significantly negatively correlated with serum iron levels．Conclusions  Compared with preterm infants appropriate for gestational age，preterm infants who are small for gestational age have lower iron reserves at birth．Adequate supplementation of iron has a promoting effect on the physical development of small for gestational age newborns．
