42例大面积烧伤病人血清维生素D水平分析

目的研究大面积烧伤病人体内血清维生素D水平情况。方法应用化学发光受体检测技术,对42例成年大面积烧伤病人血清维生素D进行检测。结果该组病人血清维生素D含量偏低,远远未达到健康人群水平(P<0.01)。结论大面积烧伤病人在长期住院后存在一定程度的维生素D不足,可能对病人的康复有负面影响,有必要在治疗过程中进行适当的补充。     

维生素D与多囊卵巢患者胰岛素抵抗相关性及其机制研究

目的:探讨维生素D对多囊卵巢综合征(PCOS)患者胰岛素抵抗(IR)的影响及其机制研究.方法:选取自2013年2月～2014年2月在该院就诊的48例PCOS患者作为PCOS组,另选30例健康育龄期妇女作为对照组,测量研究者身高、体质量参数,计算体质指数(BMI),采用全自动生化分析仪葡萄糖氧化酶检测空腹血糖浓度(FBG)、化学发光法检测血清空腹胰岛素(FI)及胰岛素样生长因子-1(IGF-1)水平、ELISA方法测定血清25-(OH)D3浓度,计算稳态胰岛素评价指数(HOMA-IR)用于评价胰岛素抵抗性,量化胰岛素敏感指数(QUICKI)用于评价胰岛素敏感度,并分析FI、HOMA-IR、QUICKI及IGF-1与血清25-(OH)D3浓度的相关性.结果:PCOS组BMI及FBG与对照组相比,差异无统计学差异(P＞0.05),而FI、HOMA-IR、QUICKI、25-(OH) D3及IGF-1与对照组比较,差异均有统计学差异(P＜0.05);并且PCOS组FI和HOMA-IR与血清25-(OH)D3浓度呈显著负相关,差异有统计学意义(P＜0.05),QUICKI和IGF-1水平与血清25-(OH)D3浓度呈显著正相关,差异有统计学意义(P＜0.05).结论:PCOS患者IR可能与血清中维生素D缺乏有关,而IGF-1分泌减少又可能是导致PCOS患者维生素D缺乏的重要原因.     

益气通脉饮联合西药治疗气虚血瘀型冠心病心绞痛90例临床疗效观察

目的:探讨益气通脉饮治疗气虚血瘀型冠心病心绞痛的临床疗效。方法:选取2017年10月—2019年2月烟台业达医院收治的气虚血瘀型冠心病心绞痛的患者90例作为研究对象,根据随机数字表法将所选患者均分为两组,每组各45例,两组的一般资料经统计学方法,差异无统计学意义(P>0.05),因此具有可比性。对照组给予常规西药进行治疗,观察组在对照组治疗基础上给予益气通脉饮治疗,1个月后比较两组临床的疗效,评估治疗前后中医证候、心绞痛症状分级和血脂水平。临床检测的数据通过统计产品与服务解决方案(Statistical Product and Service Solutions,SPSS) 19.0软件进行分析和处理,计量的数据使用平均数±标准差(x±s)表示,采用双侧t检验,计数的数据采用χ~2检验,以%表示,以P<0.05为差异有统计学意义。结果:治疗后,对照组和观察组都有一定疗效,但观察组的改善中医证候总有效率95.56%(43/45),高于对照组的82.22%(37/45),两组比较具有统计学意义(P<0.05);心绞痛的症状总有效率观察组为93.33%(42/45),对照组为77.78%(35/45),两组比较差异有统计学意义(P<0.05);与治疗前相比较,两组治疗后的三酰甘油(Triglyceride,TG)、血清总胆固醇(Serum Total Cholesterol,TC)、高密度脂蛋白胆固醇(High Density Liptein Cholesterol,HDL-C)水平均降低(P<0.05),且观察组治疗后低于对照组(P<0.05),两组治疗后的HDL-C升高(P<0.05),组间比较,差异无统计学意义(P>0.05)。结论:益气通脉饮治疗气虚血瘀型冠心病心绞痛的疗效显著,值得临床进一步研究与推广应用。

Exposición solar en la enfermedad inflamatoria intestinal ambulatoria: factores predictivos y correlación con la concentración sérica de vitamina D

IntroductionSunlight exposure is the main source of vitamin D. Our aim was to describe both sun exposure and sun protection behaviour in a series of patients with inflammatory bowel disease (IBD), and to study their potential association with vitamin D concentration.Patients and methodsA cross sectional, observational study. The clinical-demographic variables were obtained via clinical interviews and medical history review. The sunlight exposure assessment was carried out using the Sun Exposure Questionnaire and the concentration of 25-hydroxy vitamin D (25OHD) was measured by an electro-chemiluminescence immunoassay. Questionnaires were conducted on quality of life, physical activity, weekly vitamin D intake and sun protection behaviour.Results149 patients were included. In 69% of patients, deficient or insufficient 25OHD values were recorded. 67% showed low sun exposure. A modest significant correlation was observed between the total score of the solar exposure questionnaire and the 25OHD concentration in the complete series (r = 0.226, P = .006) and in the summer (r = 0.274, P = .01). The sun protection behaviour questionnaire score did not influence the 25OHD concentration. In the multivariate analysis, only the presence of clinical activity was associated with low sun exposure (OR = 3.23).DiscussionSun exposure according to the questionnaire used was low, was associated with the presence of clinical activity and was weakly correlated with serum 25OHD concentration. More studies are needed to explore the use of individual questionnaires for sun exposure and its relationship with vitamin D in patients with IBD.     

Iron Deficiency Anemia Associated With Acid-Modifying Medications: Two Cases and Literature Review

Iron deficiency anemia is often listed among potential adverse effects of gastric acid-suppressive medications, given that gastric acidity promotes intestinal absorption of nonheme iron. Additionally, the antacid calcium carbonate can inhibit iron absorption. However, there is little direct clinical evidence that proton-pump inhibitors, histamine-2 receptor antagonists, or calcium carbonate cause iron deficiency anemia. Most case reports have had substantial limitations (e.g., minimal follow-up and presence of other causes of iron deficiency), and retrospective cohort studies have lacked sufficient patient-specific detail to make strong causal inferences. We present 2 cases—both with detailed, prospective 10-year follow-up—in which combinations of proton-pump inhibitors, histamine-2 receptor antagonists and calcium carbonate were clearly associated with development of iron deficiency anemia. Overt iron-deficiency anemia is probably uncommon in patients who use acid-modifying medications and who have no other conditions that predispose to iron deficiency. Nevertheless, clinicians should be aware of this potential complication, given widespread use of these agents.
