Risk factors for an atherothrombotic event in patients with diabetic macular edema treated with intravitreal injections of bevacizumab

AIM: To identify risk factors for an atherothrombotic event (ATE) among patients who were treated for DME with intravitreal bevacizumab injections. METHODS: This retrospective study enrolled all consecutive patients with DME who were treated by intravitreal bevacizumab from 2009 through 2016 in a single center. They were divided into one group treated by bevacizumab and subsequently had an ATE and a second group also treated by bevacizumab and did not have an ATE. RESULTS: A total of 455 patients with DME were enrolled. Seventy-two of the patients had an ATE. A multivariate model adjusted for age, gender, smoking, body mass index, HbA1c, duration of diabetes, creatinine, and blood pressure revealed an increased risk for ATE in the patients with diabetic duration of more than 13y, a systolic blood pressure over 153 mm Hg at first treatment, or having been treated by more than 4 intravitreal bevacizumab injections. Additionally, patients that had an ATE within 3mo from the last intravitreal treatment underwent more bevacizumab injections (5.17±3.82 vs 3.08±1.96; P=0.0003). CONCLUSIONS: The risk factors for an ATE identified in this study were systolic blood pressure >153.5 mm Hg, a history of diabetic mellitus for more than 13y, and treatment with more than 4 intravitreal bevacizumab injections. These factors need to be borne in mind when bevacizumab is being considered in the management of patients with DME.     

中国卵巢上皮性癌维持治疗指南（2021年版）

        卵巢恶性肿瘤是女性生殖系统常见的恶性肿瘤之一，中国人群卵巢癌新发病例为52 100例/年，死亡达22 500例/年［1］。由于缺乏有效的早期筛查手段，患者就诊时多为晚期，中国卵巢癌患者5年生存率约为40%［2］。近年来，随着抗血管生成药物、聚腺苷二磷酸核糖聚合酶（poly ADP-ribose polymerase，PARP）抑制剂等靶向治疗药物的出现及相关维持治疗研究结果的公布，有效地延长了晚期患者的生存期，改变了卵巢癌的治疗策略。 浏览更多请关注本刊微信公众号及当期杂志。     

Effects of sunitinib and bevacizumab on VEGF and miRNA levels on corneal neovascularization

Aim: To evaluate the effects of sunitinib (0.5?mg/ml) and bevacizumab (5?mg/ml) on VEGF-A, VEGFR-2 and microRNA (miRNA) levels on corneal neovascularization (CNV).

Methods: In this study, CNV was induced by silver nitrate application to the cornea, and 40 Albino male rats were equally divided into four subgroups:

Group 1 (sunitinib): After silver nitrate application to the cornea, 0.5?mg/ml sunitinib eyedrop was administered twice daily for two weeks (n?=?10).

Group 2 (bevacizumab): After silver nitrate application to the cornea, 5?mg/ml bevacizumab eyedrop was administered twice daily for two weeks (n?=?10).

Group 3 (control): After silver nitrate application to the cornea, normal saline eyedrop was administered twice daily for two weeks (n?=?10).

Group 4 (vehicle): After silver nitrate application to the cornea, 1% DMSO eyedrop was administered twice daily for two weeks (n?=?10).

After two weeks from the silver nitrate application, corneas were evaluated by hand-held biomicroscope for their vascularization status. Then, corneas were excised and the expression levels of VEGFR-2, VEGF-A and the common miRNA markers for neovascularization (miR-15?b, miR-16, miR-23a, miR-126, miR-188, miR-210, miR-221, miR-222, miR-410 and miR-423) were evaluated by real-time PCR.

Results: It was seen that the CNV was decreased in sunitinib- and bevacizumab-administered groups compared to the control and DMSO groups. Also, in comparison with the control group; VEGF-A expression was downregulated by nearly 0.75 times in sunitinib group and nearly 0.52 times in bevacizumab group. VEGFR-2 expression was downregulated by 0.89 times in sunitinib group and 0.68 times in bevacizumab group, compared to the control group. miR-15?b, miR-16 and miR-126 levels were statistically lower in sunitinib and bevacizumab groups, but miR-188 and miR-410 levels were two-fold higher compared to the control group. The miR-210 level was found higher only in sunitinib group compared to the control group. There were no statistically significant changes in miR-23a, miR-221, miR-222 and miR-423 levels among the groups.

Conclusion: Topical application of bevacizumab (5?mg/ml) and sunitinib (0.5?mg/ml) decreases the levels of VEGFR-2 and VEGF-A in CNV. Further studies are needed for detailed analysis of genes which are targeted by up- or downregulated miRNAs in this study.     

贝伐珠单抗联合XELOX化疗治疗结直肠癌患者的效果及对其血清CRP水平的影响

目的:探讨贝伐珠单抗联合XELOX(奥沙利铂+卡培他滨)化疗治疗结直肠癌患者的效果及对其血清CRP(C反应蛋白)水平的影响。方法:选取2018年4月—2020年4月广东省廉江市人民医院收治的86例结直肠癌患者作为研究对象,按照计算机分组法分为对照组和观察组,每组43例。对照组采用XELOX(奥沙利铂+卡培他滨)方案治疗,观察组在对照组治疗基础上结合贝伐珠单抗治疗,每3周重复1次,共化疗3个周期,观察两组治疗效果及血清 CRP水平。结果:观察组治疗有效率为48.84 %(21/43),高于对照组的32.56 % (14/43),差异有统计学意义(P＜0.05)。治疗前观察组和对照组的血清 CRP 水平比较,差异无统计学意义(17.51±3.82 vs 17.38±3.63,P＞0.05),治疗后观察组血清CRP水平明显低于对照组(7.66±0.71 vs 11.56±2.32),差异有统计学意义(P＜0.05)。两组不良反应发生率比较,差异无统计学意义(P＞0.05)。结论:贝伐珠单抗联合XELOX化疗治疗结直肠癌患者可显著改善其炎症水平,提高免疫情况,从而提高治疗效果。
