Objective To study the health status of radiological workers who explore to long-term low-dose radiation.Methods A cross-sectional study had been investigated according to the National Ministry of Health monitoring standards of radiological workers. Results The white blood cell and platelet counts of radiological worker were less than the control group. There was a significant difference with the rate of chromosome abnormalities and the rate of micronucleus in the radiological workers(P<0.05). With the growth of length of service time, the micronucleus rate rose up. Conclusion We need to strengthen awareness of radiation protection, shorten the time of radiation exposure, increase equipment support level to protect the health of radiological workers.

Objective To investigate the biological characteristics of neuroblastomas originating from different sites. Methods Fluorescent in situ hybridization (FISH) was employed to detect the status of N-myc amplification in patients with newly diagnosed neuroblastoma originating from different sites from July 2011 to June 2013. Results A total of 49 cases of patients with newly diagnosed neuroblastoma were identified in the study, 35 cases of neuroblastoma originating from retroperitoneal site, 14 cases from other primary sites. There were significant differences in the N-myc amplification between the two groups(P<0.05). Conclusion Patients with neuroblastomas originating from extra-retroperitoneal sites might show a more favorable biological characteristics than from retroperitoneal site.

目的 探讨肝癌根治术后恶心呕吐现状及影响因素。方法 选取2022年5月—2024年5月天津市第二人民医院收治的70例肝癌患者进行回顾性分析,所有患者均行肝癌根治术,分析其术后恶心呕吐情况。并依照恶心呕吐发生情况进行分组,将30例术后发生恶心呕吐的患者分为观察组,其余40例患者为对照组。对比两组患者临床病理特征及围术期指标。并建立Logistic回归模型以术后恶心呕吐为因变量分析肝癌患者手术切除术后恶心呕吐的影响因素。结果 肝癌患者手术切除术后恶心呕吐发生率为42.86%（30/70）,其中Ⅰ度14例（20.00%）、Ⅱ度10例（14.29%）、Ⅲ度4例（5.71%）、Ⅳ度2例（2.86%）;观察组与对照组性别、体质量指数（BMI）、病理类型、临床分期、术前禁食时间对比差异无统计学意义（P>0.05）,观察组与对照组年龄及是否化疗情况对比差异有统计学意义（P<0.05）;观察组与对照组手术时间、术后VAS评分、麻醉方式、术后合并其他并发症情况对比差异无统计学意义（P>0.05）,观察组与对照组肝门阻断时间、术中失血量及术后腹胀情况对比差异有统计学意义（P<0.05）;年龄、是否化学治疗、术中失血量、术后腹胀情况为肝癌患者手术切除术后恶心呕吐的影响因素（P<0.05）。结论 肝癌患者手术切除术后恶心呕吐发生率较高,且年龄、是否化疗、术中失血量及术后腹胀情况可能为恶心呕吐发生的影响因素,针对此类患者高风险患者需及时采取相关措施进行干预,预防患者术后恶心呕吐情况及减轻严重程度。

Objective To explore the status and influencing factors of nausea and vomiting after radical resection of liver cancer. Methods A retrospective analysis was conducted on 70 liver cancer patients admitted to the Second People’s Hospital of Tianjin from May 2022 to May 2024. All patients underwent radical surgery for liver cancer,and their postoperative nausea and vomiting conditions were analyzed. According to the occurrence of nausea and vomiting, 30 patients who experienced nausea and vomiting after surgery were divided into an observation group, and the remaining 40 patients were divided into a control group. The clinical and pathological characteristics as well as perioperative indicators between two groups of patients were compared. A logistic regression model was established to analyze the influencing factors of postoperative nausea and vomiting in liver cancer patients after surgical resection,with postoperative nausea and vomiting as the dependent variable. Results The incidence of postoperative nausea and vomiting in liver cancer patients was 42. 86%（30/70）, including 14 cases of grade I, accounting for 20. 00%, 10 cases of grade II, accounting for 14. 29%, four cases of grade III,accounting for 5. 71%, and two cases of grade IV,accounting for 2. 86%. There were no significant differences in gender,body mass index（BMI）, pathological type,clinical stage,and preoperative fasting time between the observation group and the control group（P>0. 05）. However, there were significant differences in age and chemotherapy status between the observation group and the control group（P<0. 05）. There were no significant differences in the operation time,postoperative VAS score,anesthesia method and postoperative complications between the observation group and the control group（P>0. 05）, but with differences in the portal block time,intraoperative blood loss and postoperative abdominal distension between the observation group and the control group（P<0. 05）. Age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension were independent influencing factors for postoperative nausea and vomiting in liver cancer patients undergoing surgical resection（P<0. 05）. Conclusions The incidence of nausea and vomiting after surgical resection in liver cancer patients is relatively high, with age, chemotherapy, intraoperative blood loss, and postoperative abdominal distension may be influencing factors for nausea and vomiting. Therefore, relevant measures should be taken in a timely manner to intervene in high-risk patients to prevent postoperative nausea and vomiting and reduce its severity.

       目的  探讨晚期早产儿中小于胎龄儿（SGA）与适于胎龄儿（AGA）出生时的铁代谢状态。方法  选取2020年1—12月合肥市妇幼保健院收治的150例晚期早产儿（胎龄34～36⁺⁶周）作为研究对象。按照出生体质量和胎龄将早产儿分为SGA组（36例）和AGA组（114例），分析比较两组早产儿出生时的铁代谢状态，并应用多因素线性回归分析血清铁的影响因素。结果  与AGA组相比，SGA婴儿的更低的血清铁［14.5 μmol /L （11.4，17.1） vs 16.4 μmol /L（14.1，18.4），P=0.004］、更低的血清铁蛋白［135.6 μg/L（101.8，176.2） vs 172.5 μg/L（123.0，218.3），P=0.009］和更低的总铁结合力［30.4 μmol/L（26.8，34.9）vs 35.4 μmol/L（29.5，44.6），P=0.001］。两组早产儿的血红蛋白、平均红细胞体积、平均红细胞血红蛋白含量和平均红细胞血红蛋白浓度比较差异均无统计学意义（P＞0.05）。在早产儿围生期特征中，胎盘异常（β= –1.949，P=0.009）和母亲糖尿病的发生（β= –2.324，P=0.001）与血清铁水平呈负相关。结论  与早产AGA相比，早产SGA铁储备水平较低，适量补充铁元素对小于胎龄新生儿身体发育有促进作用。

       处方前置审核工作是推动临床合理用药的重要措施，对转变医院药学服务模式具有重要意义。传统处方点评为回顾性的事后点评，存在滞后性和局限性，不能实时监控合理用药。相比而言，处方前置审核可以及时、有效地干预问题处方，简化不合格处方修改流程，提高就诊患者的取药效率，而人机结合更能发挥药学信息智能化等多重优势。前置审核工作在各医院开展形式及发展水平不一，探讨新型模式，建立自主维护知识库，制定基本化原则，完善个性化原则，对前置审核系统进行全面人工筛查，可从源头上拦截或干预医生的不合理处方，促进用药规范性，提高处方或医嘱合理率，实现药学智慧信息化，辅助临床合理用药。

       目的   探讨女性医务人员月经改变的影响因素及与心理状态的相关性。方法   对深圳市3家医院女性医护人员进行随机抽样得到869份问卷调查样本，均为知情自愿参与本项调查研究。统计女性医务人员出现女性月经改变的比率和月经改变的基本特征，并采用单因素和多因素分析的方法分析影响月经改变因素。并以抑郁症筛查量表（PHQ-9）评估女性医护人员的心理状态，分析女性医务人员月经改变与心理状态评分间相关性。结果  869名女性医护人员中有293例发生月经改变，改变率为33.72%，其中月经周期改变94例、经期时间改变86例、月经量改变68例、痛经改变45例。将869例女性医护人员分为月经正常组和月经改变组，经单因素分析，两组间的年龄、职业、值夜班频率、既往病史、新冠感染等比较差异无统计学意义（P＞0.05）。月经改变组的护士占58.36%高于月经正常的24.48%，月经改变组的新冠一线抗疫人员占64.51%高于月经正常的27.08%，月经改变组合并妇科疾病史的占比20.82%（61例）高于月经正常组的占比11.98%（69例）。而月经改变组的护士、新冠一线抗疫人员、合并妇科疾病史、新冠感染的比较差异有统计学意义（P＜0.05）。多因素分析显示，职业为护士、合并妇科疾病史、新冠一线抗疫人员的P值分别为0.001、0.004、＜0.001，故而职业为护士、合并妇科疾病史、新冠一线抗疫人员是女性医务人员月经改变的危险因素。月经改变组PHQ-9评分为9.10±2.57，月经正常组PHQ-9评分为5.98±1.06，月经改变组PHQ-9评分高于月经正常组（P＜0.001）。两组受试者PHQ-9评分比较差异具有统计学意义，月经改变组PHQ-9评分中0～4分受试者为26.3%，月经正常组为47.2%，月经改变组PHQ-9评分中0～4分者比例小于月经正常组，差异具有统计学意义（P＜0.05）。结论   女性医务人员中职业为护士、合并妇科疾病史、新冠一线抗疫人员是月经改变的主要危险因素，且月经改变与心理状态有密切的相关性，需引起医疗机构的关注。
