Objectives To discover the depression status and salivary cortisol(SC)level among women with threatened preterm labor, and find their associations. Methods 138 pregnant women with threatened preterm labor were recruited in this study. Edinburgh Postpartum Depression Scale (EPDS) was applied to assess women's depression, and their saliva were collected at 8am, 16pm,23pm to test the cortisol level. EPDS≥9.5 was set as the cut-off value to assign the participants to depressive group(EPDS≥9.5) and non-depressive group (EPDS＜9.5). Independent samples t-test was used to compare the difference of salivary cortisol of the two groups, and Pearson correlation analysis was also applied to calculated the associations between depression and salivary cortisol. Results The average scores of EPDS in total women were (8.8±4.97). The incidence of depression (EPDS≥9.5) was as high as 46.4%.The average level of salivary cortisol at 8am,16pm and 23pm were(14.07±7.36) ng/mL, (9.27±5.03)ng/mL and (5.71±3.92)ng/mL respectively. EPDS in total women was associated with 8amSC(r=0.257, P=0.002) and 16pmSC(r=0.303, P＜0.001). EPDS in non-depressive group were also associated with 8amSC (r=0.306,P=0.008) and 16pmSC(r=0.203, P=0.048). Conclusion Women with threatened preterm labor have a high incidence of depression. There was a low-moderate level of association between maternal depression and salivary cortisol. Obstetrical doctors and nurses should focus on maternal psychological health level in women with threatened preterm labor. Even those individuals comparatively with a less severe depression, we need help them to minimize the severity of depression to achieve satisfying pregnant outcomes.

目的 探讨鼻咽癌(NPC)放疗致鼻窦炎发生的临床特征、影响因素。方法 回顾性分析2014年1月—2017年6月期间,我院收治的228例NPC患者临床资料,根据患者是否进行放疗,将患者分为非放疗组(106例)和放疗组(122例)。对比分析两组鼻咽癌致鼻窦炎的临床特点,以单因素和多因素Logistic分析鼻咽癌患者放疗后发生鼻窦炎的影响因素。结果 放疗组患者鼻窦炎发生率为81.97%,高于非放疗组患者鼻窦炎发生率54.72%,差异有统计学意义(P＜0.05)。放疗组鼻窦炎累及部位发生率从高到低,依次为后组筛窦、蝶窦、前组筛窦、窦口鼻道复合体、额窦以及上颌窦。放疗组患者鼻窦炎后组筛窦、蝶窦累及率高于非放疗组患者,差异具有统计学意义(P＜0.05)。单因素分析结果显示,放疗后鼻窦炎的发生,与患者年龄是否＞50岁,病程是否＞2年,是否存在鼻腔侵犯,肿瘤分期,是否使用滴鼻剂及是否进行鼻咽冲洗有关,差异有统计学意义(P＜0.05)。多因素Logistic回归分析结果显示,患者病程＞2年,存在鼻腔侵犯以及T3+T4期肿瘤是NPC放疗后鼻窦炎发生的独立危险因素;使用滴鼻剂和鼻咽冲洗是NPC放疗后鼻窦炎发生的保护因素。结论 NPC放疗后具有较高的鼻窦炎发生率,并且主要累及后组筛窦和蝶窦,对于病程＞2年、存在鼻腔侵犯以及T3+T4期肿瘤的患者,应积极采取措施预防鼻窦炎的发生,使用滴鼻剂和鼻咽冲洗是预防NPC放疗后鼻窦炎发生的有效措施。

Objective To investigate the clinical features and influencing factors of nasosinusitis caused by nasopharyngeal carcinoma (NPC) radiotherapy. Methods The clinical data of 228 NPC patients admitted to our hospital from January 2014 to June 2017 were retrospectively analyzed. According to whether the patients were treated with radiotherapy, the patients were divided into non-radiotherapy group (106 cases) and radiotherapy group (122 cases). The clinical characteristics of nasosinusitis were analyzed and compared. Univariate and multivariate logistic analysis was used to analyze the influencing factors of nasosinusitis after radiotherapy in patients with nasopharyngeal carcinoma. Results The incidence of sinusitis was 81.97% in the radiotherapy group, which was higher than that in the non-radiotherapy group (54.72%). The difference was statistical significance (P<0.05). The incidence of sinusitis involvement in the radiotherapy group was in the order of ethmoid sinus, sphenoid sinus, anterior ethmoid sinus, sinus ostium and nasal tract sinus complex, frontal sinus, and maxillary sinus. The incidences of ethmoid sinus and sphenoid sinus in the post-nasal sinusitis group were higher than that in the non-radiotherapy group (P<0.05). Univariate analysis showed that the occurrence of sinusitis after radiotherapy was related to whether the patient's age was > 50 years, whether the disease duration was >2 years, whether there was nasal invasion, tumor staging, whether nasal drops were used, and whether nasopharyngeal irrigation was performed. Multivariate logistic regression analysis showed that patients with a disease course of >2 years had nasal invasion and T3+T4 tumors were independent risk factors for sinusitis after NPC radiotherapy; use of nasal drops and nasopharyngeal washing were protective factors. Conclusion There is a higher incidence of sinusitis after radiotherapy of NPC, and mainly affects the ethmoid sinus and sphenoid sinus in the posterior group. Patients with a disease course of >2 years, with nasal invasion, and T3+T4 tumors should actively take measures to prevent the occurrence of sinusitis. The use of nose drops and nasopharyngeal washing is an effective measure to prevent the occurrence of sinusitis after NPC radiotherapy.

目的 探讨科学的出院后营养管理对肠道术后新生儿体格追赶的效果,分析影响体格追赶的相关因素。方法 通过营养门诊对出院术后婴儿及社区婴儿进行个体化营养喂养指导和营养咨询,比较两组每月体质量、身长及头围,并随访至生后9月龄。两组生后半年生长趋势行重复测量检验。结果 第1月龄时,手术组患儿体质量、身长、头围均落后于对照组婴儿(P<0.001, P=0.004, P=0.008),第2月龄时,手术组患儿体质量、头围仍落后于对照组(P=0.003,P=0.031),第4月龄时,手术组体质量低于对照组(P=0.012),第5～9月龄,两组体格指标均无明显差异。生后半年内两组的生长趋势差异无统计学意义。前半年身长的增长与出生身长、父母文化以及父亲的不良习惯存在负相关关系,头围的增长与住院天数呈明显负相关关系、与出生以及首诊时的体格状况呈正相关关系。结论 合理喂养对新生儿肠道术后体格追赶有利,帮助其接近正常生长曲线。再次手术可能是导致体质量增长下降的主要因素,但未明显影响身长、头围的正常增长。出生时和就诊时的体格状况、父母教育程度和不良习惯以及住院天数均是影响体格追赶的相关因素。

Objective To investigate the effect of scientific nutrition management after discharge on neonatal physical catch-up after intestinal operation, and to analyze the related factors affecting physical catch-up. Methods Individualized nutritional feeding instruction and nutrition consultation were performed on infants and community infants after discharge from hospital through nutrition clinic. The monthly body weight, body length and head circumference were compared between the two groups, and followed up to 9 months old. The growth trend of the two groups in half a year after birth was tested by repeated measurement. Results At the first month of age, the body weight, body length and head circumference of the patients in the operation group were lower than those in the control group (P<0.001, P=0.004, P=0.008). At the second month, the body weight and head circumference of the operation group were still behind those of the control group (P=0.003, P=0.031), and at the fourth month of age, the weight and head circumference of the patients in the operation group were still lower than those in the control group. The body weight of the operation group was lower than that of the control group (P=0.012), and there was no diffence in the physical indexes between the two groups at the age of 5~9 months. There was no statistical significance in growth trend between the two groups within half a year after birth. The growth of body length in the first half of the year had a negative correlation with the length of birth, parents' culture and father's bad habits. The growth of head circumference had a negative correlation with the length of stay in hospital, and had a positive correlation with the physical condition at birth and at first visit. Conclusion Reasonable feeding is beneficial to the physical catch-up of the newborn after intestinal operation and helps them approach the normal growth curve. Reoperation may be the main cause of weight loss, but it does not affect the normal growth of body length and head circumference. The physical condition at birth and medical visit, parents' education level, bad habit and hospitalization days were all related factors of physical catch-up.

目的 探讨急性心肌梗死患者入院首次中心粒细胞/淋巴细胞比值(neutrophil/lymphocyte ratio,NLR)与院内主要不良心血管事件(MACE)发生的相关性。方法 回顾分析2016年1月—2016年12月入住我院的急性心肌梗死患者179例,分为发生院内不良事件组(n=46)和未发生组(n=133)。采用单因素及多因素Logistics回归分析评估NLR与MACE风险的相关性。结果 179例患者中,46例患者发生院内MACE。发生院内MACE组患者的淋巴细胞计数低于未发生组(P<0.05),NLR高于未发生组(P<0.05),发生院内MACE组患者入院时的心、肾功能较未发生组差(P<0.05)。单因素回归分析显示,NLR水平与院内MACE发病率相关(OR=1.079,95%CI:1.014～1.147, P＜0.05)。多因素logistic回归分析校正性别、年龄、高血压病史、糖尿病史、Killip II级以上、收缩压、入院首次白细胞、eGFR、超敏C反应蛋白、左室射血分数及多支病变后显示,NLR是院内MACE的独立危险因素(OR=1.182,95%CI:1.034～1.352,P＜0.05);此外,超敏C反应蛋白及LVEF<50也是院内MACE的独立危险因素(P＜0.05)。结论 入院首次高NLR与急性心肌梗死患者发生院内MACE相关,是患者发生院内MACE的独立危险因素。

Objective To explore the correlation between first neutrophil/lymphocyte ratio(NLR) and in-hospital major adverse cardiac events (MACE) in patients with in patients with acute myocardial infarction. Methods Total of 179 patients with acute myocardial infarction in Guangzhou First People's Hospital from Jan 2016 to Dec 2016 were enrolled. MACE was defined as malignant arrhythmia, recurrence of myocardial infarction, target vascular reconstruction, acute left heart failure, stroke, cardiac shock and death.Baseline data and in-hospital clinical adverse events were compared among two groups. All patients were divided into two groups:MACE(+) group and MACE(-) group. Univariate and multivariate logistic regression was used to assess the correlation between NLR and in-hospital MACE. Results In-hospital MACE occurred in 46(25.7%)patients. Univariate logistic analysis showed that NLR was strongly related with MACE incidence(OR=1.079,95%CI:1.014～1.147, P＜0.05). Multivariate logistic regression analysis found that after adjusting other traditional risk factors including female gender, age, hypertension,diabetes, overKillip II grade, systolic blood pressure,first white blood cells after admitted,basic renal dysfunction,Hs-CRP,LVEF and multivessel lesions. NLR was still a significant independent predictor of in-hospital MACE in patients with acute myocardial infarction. Additionally, hs-CRP and LVEF<50% were also associated with in-hospital MACE(P＜0.05). Conclusion NLR is the independent risk factor for in-hospital MACE occurrence in acute myocardial infarction at the early admission.
