目的 探讨产科监护室妊娠期糖尿病产妇泌乳启动延迟及影响因素,以期作为预防泌乳启动延迟的参考依据。方法 选择2021年1月—2023年5月期间医院产科监护室接收的妊娠期糖尿病产妇80例为研究对象,采用单因素和多因素分析产妇的年龄、体质指数、产次、定期复查血糖、妊娠期高血压、分娩方式、开奶时间、新生儿体质量、产后焦虑、产后抑郁、产后疲乏、吸吮次数等对泌乳启动延迟的影响。结果 妊娠期糖尿病产妇泌乳启动延迟33例,发生率41.25%;泌乳启动延迟产妇的年龄≥35岁者占51.52%、未定期复查血糖者占39.39%、合并妊娠期高血压者占54.55%、开奶时间≥6 h者占57.58%、产后焦虑者占30.0%、产后抑郁者占36.36%、产后疲乏者占36.36%、吸吮次数<6次者占60.61%,与非泌乳启动延迟产妇比较差异均有统计学意义（P<0.05）。两组孕前体质指数、产次、分娩方式、新生儿出生体质量比较差异无统计学意义（P>0.05）。年龄≥35岁、未定期复查血糖、合并妊娠期高血压、开奶时间≥6 h、产后焦虑、产后抑郁、产后疲乏、吸吮次数<6次为妊娠期糖尿病产妇泌乳启动延迟的危险因素（P<0.05）。结论 产科监护室妊娠期糖尿病产妇泌乳启动延迟发生率较高,主要受到年龄、未定期复查血糖、合并妊娠期高血压、开奶时间、产后心理状态、吸吮次数等因素影响,应重视健康教育和早期辅助干预,降低泌乳启动延迟发生率。

Objective To explore the delayed lactation initiation and its influencing factors of pregnant women with diabetes in the obstetric care unit,so as to provide a reference for preventing delayed lactation initiation．Methods A total of 80 pregnant women with diabetes who were received by the hospital obstetric care unit from January 2021 to May 2023 were selected as the research objects．The age,body mass index,parity,regular blood glucose recheck,pregnancy hypertension,delivery mode,starting time,neonatal weight,postpartum anxiety,postpartum depression,postpartum fatigue,sucking times and other factors that led to the delay of lactation initiation were analyzed by single factor and multi factor analysis．Results The onset of lactation was delayed in 33 pregnant women with diabetes,with an incidence of 41.25%．The age of postpartum women with delayed lactation initiation over 35 years old accounted for 51.52%,blood sugar was not regularly rechecked accounted for 39.39%,pregnancy induced hypertension accounted for 54.55%,lactation time over 6 hours accounted for 57.58%,postpartum anxiety accounted for 30.0%,postpartum depression accounted for 36.36%,postpartum fatigue accounted for 36.36%,and sucking frequency <6 times accounted for 60.61%,which were higher than that of non-delayed lactation initiation women（P<0.05）．There was no statistically significant difference between the two groups in terms of pre pre-pregnancy body mass index,parity,delivery method and newborn birth weight（P>0.05）．The risk factors of delayed lactation initiation in pregnant women with diabetes were age ≥ 35 years,no regular blood glucose review,hypertension during pregnancy,≥ 6 h of first milk expression time,postpartum anxiety,postpartum depression,postpartum fatigue and sucking times<6（P<0.05）．Conclusions The incidence of delayed lactation initiation in pregnant women with diabetes in the obstetric care unit is high,which is mainly affected by age,pregnancy induced hypertension,time of starting breast feeding,postpartum psychological state and sucking times．Health education and early auxiliary intervention should be emphasized to reduce the incidence of delayed lactation initiation．

目的 基于计划行为理论探讨妊娠期糖尿病（GDM）孕妇自我管理行为意向,为促进其孕期良好的自我管理提供依据。方法 运用质性研究中的现象学研究方法,对12例GDM孕妇进行深度半结构式访谈,并用Colaizzi七步内容分析法对主题进行归纳。结果 根据计划行为理论对主题进行归纳,共提炼出3种类别：①行为态度：认知不足,积极态度,消极态度;②主观规范：家庭影响,医护压力,人际压力;③知觉行为控制：知识技能获取受限,客观条件束缚共8个主题。结论 GDM患者在自我管理过程中存在对疾病认知不足的问题GDM,自我管理行为受到家庭、医护人员、人际关系等外界压力对自我管理态度的影响,且存在知识技能欠缺,客观条件制约多方面阻碍。医护人员应加强对GDM孕妇的自我管理教育,适时提供支持,提高其自我管理效率。

Objective To explore the self-management behavior intention of pregnant women with gestational diabetes mellitus（GDM）based on the theory of planned behavior,and to provide a basis for promoting good self-management during pregnancy. Methods Using the phenomenological research method in qualitative research,12 pregnant women with GDM were interviewed in an in-depth semi-structured interview,and then the themes were summarized by Colaizzi's seven-step content analysis. Results According to the theory of planned behavior,the themes were summarized into three categories and eight themes including（1）Behavioral Attitudes：cognition deficiency,positive attitude,and negative attitude,（2）Subjective norms：family influence,medical pressure,interpersonal pressure,and（3）Perceptual behavior control：self-management knowledge acquisition limitations,self-management Objective conditions constraint. Conclusions Most of the respondents have insufficient awareness of self-management of gestational diabetes,different patients have different attitudes towards self-management,and self-management behavior is affected by external pressures such as family,medical staff,and interpersonal relationships,and there are many obstacles due to a lack of knowledge and skills,Objective conditions．Medical staff should strengthen the self-management education of pregnant women with gestational diabetes,provide timely support,and improve their self-management efficiency．

Objective To investigate the effects of umbilical artery hemodynamic indexes, blood lipids and thyroid stimulating hormone (TSH) on delivery outcomes in patients with gestational diabetes mellitus. Methods A total of 138 patients with gestational diabetes mellitus who were admitted to our hospital from January 2021 to November 2021 were selected and divided into a control group and a study group by random digital table, with 69 cases in each group. The differences in umbilical artery hemodynamic indexes, blood lipid indexes and TSH-related indexes and pregnancy outcomes were compared between the two groups, and multiple linear regression analysis was used to explore the relationship between umbilical artery hemodynamic indexes, blood lipid indexes, TSH, other related indexes and adverse pregnancy outcomes in patients with gestational diabetes mellitus. Results The systolic and diastolic peak volume ratio (S/D), resistive index (RI) of umbilical artery, triglyceride (TG), low density lipoprotein (LDL) and TSH in the study group were higher than those in the control group, while the levels of free triiodothyronine (FT3) and free thyroxine (FT4) were lower than those in the control group (P<0.05). The incidences of macrosomia, cesarean section, neonatal hypoglycemia and neonatal weight in study group were significantly higher than those in the control group (P<0.05). The multiple linear regression equation showed that the adverse pregnancy outcomes were correlated with changes of TG, TSH, RI, S/D, LDL levels (R²=0.224, adjusted R²=0.201; F=9.504, P<0.05), in descending order. Conclusions Abnormal levels of S/D, RI, TG, LDL, TSH and FT4 in pregnant women with gestational diabetes mellitus may affect the pregnancy outcomes. Clinical intervention measures can be taken by monitoring the changes of the above indicators.

目的 了解维持性血液析透析（MHD）合并糖尿病患者与非合并糖尿病患者人体成分的差异,对MHD合并糖尿病患者透前体液分布特点进行分析。方法 选择MHD患者66例,按是否合并糖尿病分为MHD合并糖尿病组27例和MHD非合并糖尿病组39例,收集患者的临床资料、生化指标,应用生物电阻抗法测量患者细胞外液等人体成分参数,并进行比较。结果 MHD合并糖尿病组患者细胞外液、细胞外液/总体水量、脂肪组织指数、收缩压、超滤量、血糖高于MHD非糖尿病组,差异有统计学意义;MHD合并糖尿病组患者血红蛋白低于MHD非糖尿病组,差异有统计学意义。结论 相比较MHD非糖尿病患者,MHD合并糖尿病的患者透前细胞外液、细胞外液/总体水量、脂肪含量分布异常情况更明显,高血压及贫血情况更严重。MHD合并糖尿病患者容量控制较非糖尿病组差,故需对糖尿病患者加强宣传教育,严格控制血糖水平和液体的摄入。

目的 观察2型糖尿病大鼠肝脏组织中circRNA-0003340的表达,并探讨与糖尿病的关系。方法 选取健康雄性SD大鼠30只,随机分为2组,正常对照组（NC组,n=10）与2型糖尿病组（T2DM组,n=20）,检测FPG、FINs、HbA1c、TC、TG、HDL-C、LDL-C、AST、ALT;行腹腔注射糖耐量实验和胰岛素耐量实验,计算胰岛素抵抗指数（HOMA-IR）;HE染色观察胰岛细胞形态;RT-PCR检测大鼠肝脏组织circRNA-000334的表达量。结果 与NC组比较,T2DM组的AST、ALT、FPG、HAb1c、FINs、HOMA-IR、TG、TC、LDL-C均升高（P<0.05）,HDL-C降低（P<0.05）。circRNA-0003340在T2DM组肝脏组织中的表达较NC组肝脏组织中的表达是下调的,差异有统计学意义（P<0.05）。Sperman相关分析示大鼠肝脏组织中circRNA-0003340表达水平与FPG、TG及TC呈负相关（P<0.05）。结论 circRNA-003340的表达水平可能与T2DM大鼠的糖脂代谢密切相关,circRNA-003340在肝脏组织中的表达水平下调可能参与T2DM的发生发展。
