目的 探讨市区院前急救流行病学特征,为制定院前急救策略和合理调配急救资源提供参考依据。方法 采用回顾性资料收集方法选取我院2013—2014年院前急救患者14000例(对照组),2017年院前急救患者9 630例(观察组)作为研究对象,对两组的性别、年龄、死亡原因等建立数据库,采用描述性研究和圆形分布方法进行统计分析,并对比两组数据,分析院前急救患者变化趋势。结果 对照组急救患者性别男性所占比例高于女性,年龄45~55岁所占比例最高,死亡原因创伤所占比例最高,心脑血管疾病其次;观察组急救患者性别男性所占比例高于女性,但低于对照组男性所占比例,年龄45~55岁所占比例最高,但比例低于对照组,死亡原因创伤所占比例最高,心脑血管疾病其次。结论 根据院前急救时间分布规律合理调配急救资源,充分发挥院前急救功能,提高院前急救水平。

目的 探讨STAF评分(the score for the targeting of atrial fibrillation,STAF)对心源性脑卒中(cardioembolism, CE)的预测价值,以辅助急性缺血性卒中患者病因学分型。方法 本研究为回顾性病例研究,连续入选2009年1月—2010年12月在暨南大学附属第一医院神经内科住院的急性缺血性卒中患者。所有患者严格按照STAF评分标准进行评分,按TOAST(the trial of org 10172 in acute stroke treatment,TOAST)病因学分型标准进行分型,采用SPSS 13.0软件进行统计分析,采用受试者工作特征曲线(receiver operator characteristic,ROC)来评判STAF评分对CE的预测价值。结果 共收集317例患者,其中CE 37例(11.67%)。STAF≥5提示为CE的灵敏度为89%,特异度为91%。结论 STAF评分对CE的预测有较好的作用价值,可辅助急性缺血性卒中病因学分型。

目的 观察恩替卡韦治疗e抗原阳性慢性乙型病毒性肝炎慢加急性肝衰竭(CHB-ACLF)的近期疗效及安全性。方法 选择e抗原阳性CHB-ACLF患者60例,均为我院2016年6月—2017年6月收诊,随机分为各30例的治疗组(采用恩替卡韦治疗)与对照组(采用拉米夫定片治疗),连续用药6个月后,对比疗效及安全性差异。结果 治疗6个月后,治疗组的ALB、PTA水平高于对照组,TBIL、ALT水平低于对照组,MELD评分与HBV-DNA定量少于对照组(P＜0.05);治疗后6个月,两组的HBV-DNA转阴率均高于治疗后1、3个月,且治疗组高于对照组(P＜0.05);治疗期间,治疗组患者死亡4例(13.33%),对照组患者死亡6例(20.00%),两组的死亡率比较无统计学意义(P＞0.05)。结论 恩替卡韦分散片是一种安全、有效的抗e抗原阳性CHB-ACLF药物,能有效抑制病毒复制和改善肝功能,促进患者预后转归。

目的 探讨职业性噪声暴露对广州市黄埔区某企业噪声作业工人听力损失状况的影响。方法 观察2016年8月—2018年8月,广州市黄埔区某企业噪声作业工人年度职业健康体检1 600例为调查对象,对该群体的纯音听阈测试检查结果进行分析。结果 随工龄不同听力损失发生率相比,差异有统计学意义(P<0.05),还会随着工龄的增长而增加听力损失几率;佩戴听力防护用品工人听力损失发生率低于不佩戴听力防护用品的工人,差异有统计学意义(P<0.05)。结论 噪声作业工人工龄时间越长听力损失发生率越高,防护听力用品的使用可有效降低听力损伤发生率,故在噪声作业时,企业应做好听力损伤防护措施,保障工人身心健康。

Objective To explore the related factors affecting the re-donation of the first apheresis platelet donors, and to provide a basis for the retention strategy. Methods A total of 13 899 blood donors who successfully donated apheresis platelets for the first time in Guangzhou Blood Center from January 1, 2016 to December 31, 2016 were selected as subjects. The correlation among gender, age, education level, adverse reactions of blood donation and whether platelet collection was re-donated in the next year was analyzed. Results Re-donation rate of male blood donors (10.68%) was higher than that of female blood donors (8.94%). The difference was statistically significant (P<0.01). Re-donation rate of blood donors aged 18～25 was the highest 12.86%, and that of 46～60 was the lowest 6.46%. The difference was significant (P<0.001). Re-donation rate of high school or vocational college blood donors was the highest 11.23%. The lowest re-donation rate was 8.94% in the undergraduate group or above, and the difference was statistically significant (P< 0.001). The re-donation rate of donors without adverse reactions (10.37%) was higher than that of donors with adverse reactions (5.56%). The difference was statistically significant (P<0.01). Conclusion Male, younger, less educated and no adverse reactions to blood donation are more willing to return to donate platelet again. Targeting these donors for reserve measure will conducive to the establishment of a fixed platelet donor team.

目的 分析肺肝样腺癌(HAL)的临床病理特征、诊断、免疫表型、基因检测及治疗预后等。方法 对1例HAL临床及影像学、组织学形态、免疫组化及基因检测结果等进行观察,并结合相关文献综合分析。结果 患者为48岁吸烟男性,镜下肿瘤具有肝细胞样和腺样分化特征,血清AFP升高。免疫组化: Hepatocyte,AFP, Arginase-1均阳性,ARMS-PCR法均未检测到EGFR,ALK/ROS1,KRAS及BRAF突变。结合相关文献分析: HAL常见于有吸烟史的男性,血清AFP值升高也是该肿瘤的一个特点。肿物多见于肺上叶,体积较大,易发生淋巴结和远处转移,预后相对较差。结论 HAL非常少见,易误诊,其诊断需结合形态学特点、临床病理特征及免疫组化结果等。

Objective To explore the clinicopathologic characteristics, diagnosis, immunophenotype, gene detection and prognosis of primary hepatoid adenocarcinoma of the lung (HAL). Methods A case of hepatoid adenocarcinoma of the lung was analyzed with clinical manifestations, histology, immunohistochemical staining and gene detection, and relevant literatures were reviewed. Results The patient was a 48-years-old man with smoking history. Microscopically, the tumor has the characteristics of hepatocellular carcinoma and adenoid differentiation, also serum AFP was elevated. The immunohistochemical results showed that Hepatocyte, AFP and Arginase-1were positive. No mutations were detected for EGFR, ALK/ROS1, KRAS and BRAF by ARMS-PCR. Combining with literature analysis, HAL is common in males and most patients with this tumor are smokers. Serum AFP in very high levels has been a distinguishing feature of this tumor. HAL usually presents as a large bulky solitary mass in the upper lobe. Lymph nodes and distant metastases are prone to occur. Therefore, the prognosis is very poor. Conclusion HAL is a rare malignant tumor and easy to be misdiagnosed. The diagnosis of primary hepatoid adenocarcinoma of the lung should be combined with morphological features, clinicopathological features and immunohistochemical findings.

目的 对比分析自动弹力线痔疮套扎术(RPH)与外剥内扎术联合治疗及吻合器痔上黏膜环切术(PPH)单独治疗重度混合痔的临床疗效。方法 选取2017年5月—2018年5月我院收治的100例重度混合痔患者,将其随机分为研究组(50例)与对照组(50例)。对照组患者采取PPH治疗,研究组患者采取RPH联合外剥内扎术治疗,对比两组患者治疗效果、手术相关指标,并观察术后肛门功能评分差异。结果 研究组患者的临床疗效高于对照组(P<0.05);手术时间及术中出血量、住院时间两组患者比较,研究组低于对照组(P<0.05)。研究组患者术后干便、气体、稀便、生活方式发生变化、需衬垫等肛门功能评分低于对照组(P<0.05)。结论 RPH与外剥内扎术联合治疗重度混合痔效果优于单独应用PPH治疗,值得临床推广。

Objective To study the efficacy and its influence on anal function of RPH combined with external ligation and internal ligation in the treatment of severe mixed hemorrhoids. Methods 100 patients with severe mixed hemorrhoids admitted to our hospital from May 2017 to May 2018 were selected as research subjects. They were randomly divided into the study group and the control group, 50 cases in each group. The control group was treated with PPH, and the study group was treated with RPH combined with external stripping and internal ligation. The therapeutic effect and operation related indexes of the two groups were compared, and the postoperative anal function scores were observed. Results The clinical efficacy of the study group was higher than that of the control group (P<0.05), and the intraoperative bleeding volume, operation time and hospitalization time of the study group were lower than that of the control group (P<0.05). The anal function scores such as dry stool, gas, dilution, lifestyle changes and padding requirement in the study group were lower than those in the control group (P<0.05). Conclusion RPH combined with external stripping and internal ligation is better than PPH alone in the treatment of severe mixed hemorrhoids.
