Objective To investigate the impact of decitabine (DAC) combined with thalidomide on dyshaematopoiesis and efficacy in patients with myelodysplastic syndrome (MDS). Methods Patients with MDS admitted to our hospital from June 2014 to May 2020 were selected as the research population.Among them, 60 MDS cases were selected by convenience sampling method, which had poor therapeutic effect with treatment of blood transfusion, anti-infection and cytokines treatments such as erythropoietin (EPO)+ colony stimulating factor (CSF). The control group and the observation group were set up according to the principle of complete block, and the control group was treated with thalidomide while the observation group was treated with decitabine (DAC) on the basis of the control group.The efficacy, hemogram-related indicators, improvement of dyshaematopoiesis and prognosis outcomes were compared between the two groups. Results The overall response rate (ORR) of the observation group was higher than that of the control group (51.61%vs 26.67%, P<0.05). After treatment, the levels of platelet (PLT), hemoglobin (HGB) and absolute neutrophil count (ANC) in the two groups were increased to a certain extent while the level of bone marrow blasts(bls) was decreased, and the levels of PLT, HGB and ANC of the observation group were higher than those of the control group while the level of bls was lower (P<0.05). The follow-up deadline was May 2020, and the follow-up time was 8-96 months and the median follow-up time was 68 months.During treatment and follow-up, bone marrow morphology examination and chromosome karyotype identification results were normal.Regarding the improvement of dyshaematopoiesis, the difference in T1 rate between the two groups was not statistically significant (P>0.05). The revised International Prognostic Scoring System prognosis score of the observation group was better than that of the control group (P<0.05). There were no statistically significant differences between the two groups in terms of grade I~IV adverse reactions (P>0.05). The 5-year overall survival rate of the observation group was 63.33%, which was higher than 36.67%of the control group (P<0.05). Conclusion Compared with thalidomide only treatment, the application of decitabine combined with thalidomide in the treatment of MDS had a more accurate efficacy, improved hemogram indicators, and had a certain T1 rate and good prognosis outcomes.

目的 系统评价胰岛素联用α-葡萄糖苷酶抑制剂(AGIs)治疗成人1型糖尿病(T1DM)的疗效和安全性。方法 检索中英文数据库,纳入关于胰岛素联用AGIs治疗成人T1DM患者的随机或非随机对照试验。使用Review Manager 5.3软件进行Meta分析。结果 共纳入10项研究,616例患者。与安慰剂或空白对照相比,在有效性方面,胰岛素联合AGIs可改善成人T1DM患者的糖化血红蛋白;降低平均血糖、空腹血糖和餐后2小时血糖;改善血糖波动情况,包括平均血糖波动幅度和最大血糖波动幅度(均P<0.05)。在安全性方面,AGIs增加总不良反应发生的风险(P<0.05),其中主要是胃肠道不适,但未增加低血糖的发生率和发生次数(均P>0.05)。胰岛素联合AGIs减少了每日胰岛素总剂量(P<0.05),但对体重、甘油三酯和高密度脂蛋白胆固醇无显著影响(均P>0.05)。结论 胰岛素联合AGIs可降低成人T1DM患者的糖化血红蛋白,改善血糖水平和血糖波动情况。AGIs不会增加低血糖的风险,但需重视其不良反应,特别是胃肠道不良反应。

Objective To systematically evaluate the efficacy and safety of adding alpha-glucosidase inhibitors (AGIs) to insulin therapy in adult patients with type 1 diabetes (T1DM). Methods Articles about randomized or non-randomized controlled trials of insulin combined with AGIs in adult patients with T1DM were retrieved from Chinese and English database. Meta-analyses were performed by using Review Manager 5.3. Results A total of 616 patients were included from 10 clinical trials. Compared with adding placebo or nothing, in terms of efficacy, the addition of AGIs resulted in decreased HbA1c, mean blood glucose, fasting plasma blood glucose and 2-hour postprandial blood glucose levels (all P<0.05). And this scheme improved the glucose variability including mean amplitude of glycemic excursions and the largest amplitude of glycemic excursions (P<0.05, respectively). As to safety, AGIs increased the risk of total adverse reactions (P<0.05), most of them were gastrointestinal complaints, while the occurrence and the frequency of hypoglycemia were similar (P>0.05, respectively). This scheme could also lead to the reduced total daily insulin dose (P<0.05) but had no significant effect on body weight, triglyceride or cholesterol concentration (P>0.05, respectively). Conclusions The addition of AGIs to insulin therapy in adult patients with T1DM may reduce HbA1c and improve the glucose levels and glucose variability. But total adverse effects especially the gastrointestinal complaints should also be considered in the use of AGIs although it does not increase the risk of hypoglycemia.

目的 回顾性分析CT血管成像(CTA)在急诊出血性脑卒中患者中,在病因诊断、病程进展评估中的应用。方法 89例头颅平扫初诊急性出血性脑卒中病人,行CTA检查,通过后处理技术,对各种出血原因进行影像学特征分析,并根据图像特征评估血肿的稳定性,在24小时内复查CT平扫了解出血的发展。结果 89例急诊脑出血患者,CTA检查中83例病因明确,并采取相应的临床处理。5例(5.6%)病因不明确,以蛛网膜下腔出血患者为主,需临床进一步全面检查。1例患者不配合造影检查失败。CT平扫发现不稳定血肿22例,复查血肿增大16例,准确率72.2%。CTA判断血肿内持续出血患者14例,复查13例患者有血肿增大,准确率为92.8%。结论 CT平扫只能评估血肿的稳定性,而CTA出现血肿内高密度影时,高度提示血肿内出血仍在持续。急诊医生可通过CTA对脑出血患者进行病因的分析、病程的预估、及时诊断、定位,对指导治疗及手术方式有重要作用。

Objective To retrospectively analyze the value of computed tomographic angiography (CTA) on etiological diagnosis and progression evaluation in patients with emergent hemorrhagic stroke. Methods Eighty-nine patients with preliminary diagnosis of acute hemorrhagic stroke underwent CTA, then various bleeding causes were analyzed by post-processing.The stability of hematoma was evaluated according to the image features.Follow-up CT in 24 h were performed to show the development of hemorrhage. Results In 89 cases of patients with emergent cerebral hemorrhage, 83 cases had made clear diagnosis according to CTA, then the patients received specialized clinical management.The causes of hemorrhage were not clear in 5 cases (5.6%), and subarachnoid hemorrhage was found in the most of these patients, requiring further examination.Twenty-two cases of unstable hematoma were found by CT scan, and hematoma enlarged in 16 cases in follow-up scan, with an accuracy of 72.2%.Fourteen patients were diagnosed as persistent bleeding hematoma by CTA, among them 13 patients showed hematoma enlargement, with an accuracy of 92.8%. Conclusions CT scan can only evaluate the stability of the hematoma, but the CTA high density in the hematoma strongly suggests persistent bleeding in the hematoma.Emergency doctors can analyze the cause of cerebral hemorrhage, assess the progression of disease, timely diagnose, locate the bleeding point by CTA, and there is important value in guidance of treatment and surgical methods.
