Intermediate and long term clinical effects of uterine arterial embolization with sodium alginate microspheres in treatment of diffuse adenomyosis

OBJECTIVE: To study intermediate and long term efficacy of uterine arterial embolization (UAE) with sodium alginate microspheres (KMG) at diameters 500-00 microm in treatment of diffuse adenomyosis. METHODS: Totally 40 patients with standard diffuse adenomyosis were enrolled and treated with UAE. KMG at diameters 500-700 microm for vascular embolization were used to embolize the arteries. The degree of dysmenorrhea, amount of menorrhea and uterine volume, as well as the level of serum CA125, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) were investigated before and after UAE. RESULTS: The follow up rates were 100% (40/40), 100% (40/40), 80% (32/40), 68% (27/40), 58% (23/40) after uterine arterial UAE 12, 24, 36, 48 and 60 months respectively. The early, intermediate and long-term effective rates were 90% (36/40), 88% (28/32), 83% (19/23). The degree of dysmenorrhea, the amount of menorrhea and the uterine volume, as well as serum CA125 all decreased significantly 3 months after UAE at varying degrees (P < 0.05). Compared with other follow-up time, the degree of dysmenorrhea and the amount of menorrhea declined to their lowest point at 6 month after UAE (P < 0.01). Paralleled with the decrease of volume of uterine, serum CA125 also decreased significantly and reached the lowest level 12 months later compared with other follow-up times (P < 0.01). Even at the 12th month after UAE serum CA125 was not normal and FSH, LH and E2 did not change all the times after UAE, (P > 0.05). No recurrence was found during the 60 months after UAE. CONCLUSION: KMG used in UAE at diameters 500-700 microm has good intermediate and long term effectiveness in treatment of diffuse adenomyosis with no side effects.     

Cumulative and residual risks of small for gestational age neonates after changing pregnancy-smoking behaviors

This retrospective cohort study examines the relationship between changing pregnancy-smoking behaviors, from the first to the second pregnancy, on second-pregnancy rates of small for gestational age (SGA) neonates. Electronic birth records provided data on 5107 pregnant women who had two singleton births in Kansas City, MO, from 1994 to 2003. Pregnancy-smoking behavior was classified by smoking status (nonsmoker [NS] or smoker [SMK]) during the first (previous)/second (current) pregnancy: NS/NS, NS/SMK, SMK/SMK, and SMK/NS. The overall second-pregnancy SGA rate was 6.7% and varied with pregnancy-smoking behavior: 5.9%, NS/NS; 6.6%, SMK/NS; 12.5%, NS/SMK; and 12%, SMK/SMK; P < 0.001 Current pregnancy-smoking was associated with increased odds ratio (OR) of SGA; SMK/SMK (OR, 2.80; 95% confidence interval [CI], 2.00 to 3.93) versus NS/SMK (OR, 1.83; 95% CI, 1.19 to 2.82) versus SMK/NS (OR, 1.31; 95% CI, 0.65 to 2.65) versus NS/NS (OR, 1.00; 95% CI, reference). Being black (OR, 3.73; 95% CI, 2.91 to 4.79) and having medical risk factors (OR, 1.31; 95% CI, 1.09 to 1.74) also were significantly associated with a SGA neonate in second pregnancy. In conclusion, risk of delivering a SGA neonate in a current pregnancy is related to current rather than previous pregnancy-smoking. Therefore, antismoking socialization during pregnancy should focus on preventing and stopping current pregnancy-smoking, irrespective of past behavior.     

抗氧化剂在防治阿尔茨海默病中的效果和安全性评价

阿尔茨海默病（Alzheimer＇s disease,AD）属于常见的神经退行性疾病,以进行性认知功能减退为主要特征,至今病因未明,也没有治愈AD的有效方法.抗氧化剂可以清除体内自由基,有助于预防和治疗与氧化应激相关的疾病,现已在抗衰老以及肿瘤、心血管疾病的防治中广泛使用.近年来,国内外学者尝试用抗氧化剂防治AD,但其使用剂量不同于在防治其他疾病时的用量,可能会带来潜在的危险.抗氧化剂在防治AD中的疗效和安全性究竟怎样？近年来出现了越来越多的负面结果和讨论,因此有必要客观评价该类药物在AD中的临床效果和安全性.     

Effect of Qingre Quyu Granule (清热祛瘀颗粒) on stabilizing plaques in the brachiocephalic artery of apolipoprotein E deficient mice

Objective： To investigate the effect of Qingre Quyu Granule （清热祛瘀颗粒, QRQYG） on stabilizing vulnerable plaques in apolipoprotein E （ApoE） defficient mice. Methods： Seventy-two male ApoE defficient mice were given a high-fat diet from 6 weeks of age. At the 16th week, all the mice were randomized into 3 groups： the QRQYG group, the simvastatin group, and the control group. Sixteen weeks after administration of 0.9 g/kg QRQYG, 3 mg/kg simvastatin or 10 mg/kg sodium chloride per day to the respective groups, the animals were euthanized. The pathological morphologic changes in the vulnerable plaques were evaluated, the matrix metalloprotease-9 （MMP-9） expression was measured by immunohistofluorescence, the soluble intercellular adhesion molecule 1 （ICAM-1） was determined by ELISA, the nuclear factor kappaB （NF-κB） subunit p65 was measured by quantitative RT-PCR, and, finally, thrombospondin-1 （TSP-1） was determined by the immunohistochemical method. Results： The plaque cross-sectional area in the brachiocephalic artery （23.7%, P0.01）, the lipid core of the plaque （43.1%±3.1%）, and the number of buried ？brotic caps of the plaque were significantly decreased in the QRQYG group compared to the control group （both P0.01）; furthermore, the thickness of the ？brotic cap of the plaque increased and the intra-plaque hemorrhage of the plaque decreased. The serum soluble ICAM-1 （27.1±5.1 μg/mL）, the protein expression of MMP-9 and TSP-1 and the p65 mRNA expression increased in the QRQYG group in comparison with the control group （P0.05 or P0.01）. Conclusion： QRQYG could stabilize the vulnerable plaque through inhibition of the inflammatory response.     

环氧化酶-2预测经尿道膀胱肿瘤电切术后肿瘤复发的意义

目的探讨环氧化酶-2(C0X-2)在预测经尿道膀胱肿瘤电切术(TURBT)后肿瘤复发中的作用。方法收集52例行TURBT治疗的膀胱肿瘤患者资料,采用免疫组化方法检测肿瘤组织标本中COX-2的阳性表达,分析其与患者临床病理资料以及术后随访资料间的相关性。结果 52例标本中COX-2阳性表达30例,术后平均随访28.6个月,复发9例。COX-2阳性表达率与肿瘤T分期明显相关(P0.05),与患者年龄、性别、病理G分级、单/多发病灶之间没有相关性,单因素分析显示膀胱肿瘤术后复发与临床T分期(P0.01)、单/多发病灶(P0.05)密切相关,而与COX-2阳性表达率、肿瘤G分级、性别没有相关性。结论 COX-2作为TURBT术后肿瘤复发的预测因子及其具体机制有待进一步研究。     

2型糖尿病患者血清铁蛋白水平与血尿酸的关系

[摘要]目的 探究2型糖尿病（T2DM）患者血清铁蛋白(SF)水平与血尿酸(SUA)水平之间的关系。方法 选取2021年8月至2022年9月兰州大学第一医院内分泌科住院治疗的T2DM患者400例,根据SF的四分位数水平将其分为4组：Q1组(<75.9ng·mL－1)、Q2组[(76.0-141.0)ng·mL－1]、Q3组[(141.1-244.4)ng·mL－1]、Q4组[(>244.5)ng·mL－1],比较不同SF水平组SUA水平、高尿酸血症（HUA）患病率的差异。此外,T2DM患者分为高尿酸血症组（HUA）和非高尿酸血症组（NHUA）,比较两组之间SF水平及高铁蛋白血症患病率之间的差异。Spearman相关性分析、线性回归分析T2DM患者SF与SUA之间的相关性。以T2DM是否合并HUA为因变量,性别、年龄、体质指数、糖化血红蛋白、甘油三酯、SF为协变量,二元logistic回归分析T2DM患者HUA发生的独立影响因素。结果 T2DM患者Q1组SUA水平[(306.64±80.16)μmol·L－1 ]显著低于Q2、Q4组[(333.16±75.93)μmol·L－1和(341.62±98.19)μmol·L－1,P均<0.05],不同SF水平组间HUA患病率无统计学差异性。HUA组SF水平[159.80(103.60-290.25)ng·mL－1]显著高于NHUA组[130.00(69.43-236.75)ng·mL－1,P<0.05],高铁蛋白血症的患病率（18.33%）高于NHUA组（17.35%）,但未达到统计学显著性。Spearman相关性分析提示SUA水平与SF正相关（rs=0.110,P=0.028)。多元线性回归分析提示T2DM患者SF与SUA水平独立正相关。Logistic回归分析显示T2DM患者SF水平与HUA独立正相关（OR=1.002,P=0.044）。结论 T2DM患者SF水平与SUA密切相关,SF是T2DM患者HUA发生的独立影响因素。
