Objective To determine the relationship among C677T and A1298C gene polymorphisms of methyltetrahydrofolate reductase（MTHFR）and adult acute lymphocytic leukemia（ALL）, the relationship between the toxicity of high-dose methotrexate（HD-MTX）after chemotherapy and the MTX blood concentration of 24 h, 48 h and 72 h in patients with ALL．Methods Blood samples were collected from 75 adult patients with ALL who were treated at the First Affiliated Hospital of Xinjiang Medical University from June 2014 to June 2020．The samples were used to detect the genetic polymorphisms of MTHFR C677T and A1298C, and the toxic reactions were graded according to the common toxic reaction classification criteria of anti-cancer drugs．Unconditional Logistic regression was used to analyze the relationship between MTHFR C677T and A1298C gene polymorphisms and HD-MTX toxic reactions and blood drug concentration．Results The risk of anemia in MTHFR 677TT was significantly higher than that in CC type（P=0.027, OR=4.694, 95% CI：1.195-18.438）．No correlation was found between MTHFR C677T and leukopenia, thrombocytopenia, neutropenia, lymphogranulocytopenia, bone marrow suppression, elevated alanine aminotransferase, elevated aspartate aminotransferase, liver function injury, acute kidney injury and mucosal injury, 24 h, 48 h and 72 h MTX plasma concentrations（>0.05）．No correlation was found among MTHFR A1298C and HD-MTX toxicity and blood concentration（P>0.05）．Conclusions MTHFR C677T gene polymorphism is associated with hematotoxicity after HD-MTX chemotherapy in adult patients with ALL．

目的 对比分析甲氨蝶呤(methorexate,MTX)联合超声监视下清宫与甲氨蝶呤、子宫动脉栓塞术(uterine artery embolization,UAE)联合清宫治疗停经7周内Ⅱ-Ⅲ型剖宫产瘢痕妊娠(ceasarean scarpregnancy,CSP)的效果。方法 回顾性分析我院自2016年1月—2017年12月收治的停经7周内Ⅱ-Ⅲ型CSP患者的临床资料,按随机、平衡、对照原则分别筛选69例MTX+清宫治疗患者作为A组,68例MTX+UAE+清宫治疗患者作为B组,对比两组治疗成功率、一般治疗情况及术后并发症发生率,并统计两组月经周期恢复时间、血β-hCG恢复至正常时间、疤痕妊娠病灶消失时间。结果 两组术后恢复良好,术中、术后均未发生不可控制宫腔出血现象,胎囊组织均全部清出,A组术中出血量、子宫切除发生率、发热、术后盆腹腔疼痛及肝功能损伤发生率均低于B组,术后第1天血β-hCG下降超过50%及治疗成功率、住院时间均高于B组,且该组月经周期恢复时间、血β-hCG恢复至正常时间、疤痕妊娠病灶消失时间亦较B组短(P﹤0.05)。结论 于停经7周内Ⅱ-Ⅲ型CSP患者而言,行MTX+清宫治疗或可在不增加出血风险基础上避免UAE相关并发症及副反应。

Objective To comparatively analyze the effects of methotrexate (MTX) combined with uterine curettage under ultrasonic monitoring and MTX, uterine artery embolization (UAE) combined with uterine curettage in the treatment of cesarean scar pregnancy (CSP) within 7 weeks of menopause. Methods The clinical data of patients with type Ⅱ-Ⅲ CSP within 7 weeks of menopause who were admitted to the hospital from January 2016 to December 2017 were analyzed retrospectively. Another 69 cases treated with MTX combined with uterine curettage were selected as group A and 68 cases treated with MTX+UAE+uterine curettage were selected as group B. The success rate of treatment, general situation of treatment and the incidence of adverse reactions were compared between the two groups. The time of menstrual recovery, the recovery time of blood β-hCG and the disappearance time of scar pregnancy lesions were statistically analyzed. Results The two groups recovered well after operation, and there was no uncontrollable uterine bleeding. All fetal sac tissues were cleared. The intraoperative blood loss, hysterectomy rate, incidence rates of fever, postoperative abdominopelvic pain and liver function injury in group A were less/lower than those in group B, The rate of blood β-hCG decreasing more than 50% on the 1st day after operation, the success rate of treatment and hospitalization time of groups A were higher/longer than those of group B, while the time of menstrual recovery, recovery time of blood β-hCG and the disappearance time of scar pregnancy lesions was shorter than that of group B(P<0.05). Conclusion MTX combined with uterine curettage may avoid complications and side effects of UAE in patients with type Ⅱ-Ⅲ CSP within 7 weeks of menopause, without increasing the risk of bleeding.
