Use of low molecular weight heparin and hemoglobin fall in COVID-19 patients: A STROBE-compliant study

In patients with coronavirus disease 2019 (COVID-19), anticoagulation was suggested as a mitigating strategy. However, little research has been conducted on the adverse consequences of anticoagulant medication. This study aimed to investigate the adverse effect of low molecular weight heparin (LMWH) on hemoglobin fall in COVID-19 treatment. The electronic medical records of COVID-19 patients with pneumonia were collected (including clinical characteristics, vaccination status, complete blood count, coagulation profile, inflammatory cytokines, serum biochemical indicators, and computerized tomography imaging score). Whether they received LMWH, patients were divided into the LMWH group and the control group. Count data were represented as frequency distribution, and a 2-tailed test was used to compare the 2 groups. Spearman rank correlation was used to evaluate the interrelation between changes in hemoglobin and LMWH. The confounding factors were excluded by logistic regression analysis. A total of 179 COVID-19 pneumonia patients were enrolled (81 in the LMWH group and 98 in the control group). The change in hemoglobin was −6.0g/L (IQR −10.8 to 1.0) in the LMWH group and −2.0g/L (IQR −7.0 to 4.0) in the control group (P < .001, between-group difference, −5.0 g/L; 95% confidence interval, −7.0 to −3.0, calculated with the use of the Mann–Whitney U test and the Hodges–Lehmann estimate of confidence intervals for pseudo-medians). The results of multivariate regression analysis showed that after adjusting for confounding factors, LMWH use was not associated with a decrease in hemoglobin (P > .05). In nonsevere COVID-19 patients with pneumonia, the preventive use of LMWH did not lower hemoglobin.

糖化血清白蛋白在2型糖尿病患者中的临床应用

目的分析2型糖尿病患者糖化血清白蛋白(GA)与各常用血糖参数的相关性及GA的影响因素,评价GA与糖尿病微血管并发症的相关性。方法 2007年5月—2009年10月我院2型糖尿病住院患者1 597例。患者入院初测定空腹静脉血糖(FPG)、餐后2 h血糖(2hPG)、GA、糖化血红蛋白(HbA_(lc))、24 h尿白蛋白定量,并行连续血糖监测(CGMS),全部患者均由眼科医生眼底摄片。结果 2型糖尿病患者入院时GA值为(25.8±7.8)%,HbA_(lc)为(9.0±2.3)%。GA与HbA_(lc)、FPG、2hPG、CGMS血糖均值均正相关(r=0.788、0.396、0.406、0.470,均P<0.01)。体重指数、2hPG、CGMS血糖均值是影响GA的主要因素。GA>17%组患者糖尿病视网膜病变的检出率高于GA≤17%组(P<0.01),GA>17%组患者糖尿病肾病的检出率与GA≤17%组间无显著差异(P>0.05)。结论 GA是一个可准确反映短期内平均血糖水平及变化的优良且检测方便的指标,GA与糖尿病视网膜病变的发生相关。     

冠心病并糖耐量减低患者静脉血中Fig、GHbA_（1c）水平与冠脉病变的关系

目的：研究在冠心病合并糖耐量减低患者中纤维蛋白原（Fig）、糖化血红蛋白A1c（GHbA1c）水平与冠脉病变支数的关系。方法：106例经OGTT试验确诊的糖耐量减低患者,根据冠脉造影结果分为对照组（A组）,单支冠脉病变组（B组）,多支冠脉病变组（C组）,分别测定3组血中Fig,GHbA1c水平。结果：B组中的Fig、GHbA1c水平较A组升高（P〈0.05）,C组中的Fig、GHbA1c水平较A组明显升高（P〈0.01）,并且C组中的Fig水平较B组升高（P〈0.01）,C组中的GHbA1c水平较B组升高（P〈0.05）。A组血浆中Fig与GHbA1c之间无相关性（P〉0.05）,B组血浆中Fig与GHbA1c之间有相关性（P〈0.05）,C组血浆中Fig与GHbA1c之间有相关性（P〈0.01）。结论：糖耐量减低合并冠心病患者血清GHbA1c及Fig水平明显升高,且二者水平与冠状动脉病变严重程度密切相关,联合检测血清GHbA1c及Fig水平可用于评价糖耐量减低患者冠状动脉粥样硬化程度。

Two generation reproduction and teratogenicity studies of feeding cyadox in Wistar rats

To investigate the teratogenic potential and reproductive toxicity of cyadox, a growth promoting agent, Wistar rats (F₀) were fed with diets containing cyadox (0, 50, 150 and 2500 mg/kg) or olaquindox (150 mg/kg), approximately equivalent to cyadox 5, 15, 250 or olaquindox 15 mg/kg b.w./day across two generations. Half of the pregnant rats (F₀, F_1b) were subjected to caesarean section on gestational day 20 for teratogenic examination and the other half produced pups F_1a and F_2a, respectively. At the 250 mg/kg b.w./day cyadox group, body weights of F_1b pregnant rats and F_2a on day 21 after birth decreased; fetal body lengths and tail lengths decreased; the number of fetal resorptions increased significantly; litter weights, number of viable fetuses decreased; number of embryo resorptions increased significantly; number of liveborn F_1a, F_1b and F_2a decreased. No macroscopic or microscopic change of any significance was found in the reproductive organs. Significant increases in the incidence of cervial ribs or lumbar ribs in F_2a pups and significant increases of relative organ weight of testis and epididymis in F_1b were observed at the 250 mg/kg b.w./day cyadox group. The NOAEL for reproduction/development of cyadox for rats was estimated to be 150 mg/kg diet, which was equivalent to approximately 15 mg/kg b.w./day.     

血红蛋白QuongSze的临床研究

目的分析血红蛋白Quong Sze(Hb QS)的临床表现及血液学参数,探讨Hb QS的临床及血液学特点。方法选择在广西医科大学第一附属医院就诊的患者。对病例进行血常规检查;应用高效液相法进行Hb分析;应用反向点杂交、多重PCR进行珠蛋白生成障碍性贫血(地贫)基因突变分析;应用SPSS 13.0统计软件对数据进行统计分析。结果 9 176例病例中,检出Hb QS杂合子50例(其中8例复合β地贫)及HbH-QS病30例。Hb QS杂合子无临床症状,Hb分析未见异常,其血常规检测显示42例HbQS杂合子平均红细胞容积(MCV)为(73.72±3.57)fL,8例复合β地贫MCV为(63.06±4.59)fL;45例Hb正常,5例Hb稍低于正常值范围。HbH-QS病的临床表现轻重不等,大部分中度至重度贫血,需要不定期输血治疗,少部分表现为轻度贫血;血液学检测为小细胞低色素性贫血;Hb分析显示Hb H为(26.32±8.61)%。结论 Hb QS杂合子具有MCV降低的血液学特征,为首次报道。提示在地贫高发区,当血常规检测仅有MCV降低时应考虑Hb QS杂合子的可能,通过基因分析确诊。HbH-QS病临床表现具有多样性,需在遗传咨询中予以解释说明。
