目的 探究肺表面活性物质联合高频振荡通气治疗新生儿呼吸窘迫综合征的有效性及安全性。方法 选取我院新生儿科2016年2月—2018年7月收治的120例呼吸窘迫综合征新生患儿作为研究对象,随机将其分为常规组和试验组,每组各60例。常规组实施肺表面活性物质联合常频振荡通气治疗,试验组采取肺表面活性物质联合高频振荡通气治疗,比较两组治疗前后的肺氧合功能和并发症发生情况。结果 PaO₂、OI、a/A PO₂等指标在治疗前两组差异无统计学意义(P＞0.05),治疗后试验组均要优于常规组,差异有统计学意义(P＜0.05);常规组的并发症发生率为35.0%(21/60),试验组的并发症发生率为18.3%(11/60),试验组低于常规组,差异有统计学意义(P＜0.05)。结论 新生儿呼吸窘迫综合征采用肺表面活性物质联合高频振荡通气治疗效果显著,并发症少,安全性高。

目的 探讨一次不明原因流产与精子DNA损伤的关系。方法 收集有一次不明原因流产史的患者作为实验组,同时以有正常妊娠史的患者为对照组,分别比较两组男方年龄、精子密度、精子活力、精液量和精子DNA断裂指数有无差异。以SPSS 16.0为统计软件,进行独立样本的t检验。结果 两组的精液量、精子密度及活力均无差异,实验组男方年龄小于对照组(P<0.05),但实验组的DFI要高于对照组(P<0.01)。结论 本研究对照组年龄高于实验组,而DFI正好相反。这说明不明原因的自发流产与男方精子DFI密切相关,随着DFI的增加,流产风险增加。

Objective To investigate the relationship between unexplained abortion and sperm DNA damage. Methods Patients with a history of unexplained abortion were enrolled as an experimental group, and patients with a normal pregnancy history were used as a control group. The differences in age, sperm density, sperm motility, semen volume, and sperm DNA break index were compared between the two groups. The independent sample t test was performed using the statistical software of SPSS 16.0. Results There was no significant difference in semen volume, sperm density and motility between the two groups. The age of the male group in the experimental group was lower than that in the control group (P<0.05), but the DFI of the experimental group was higher than that of the control group, and the difference was statistical significance (P<0.01). Conclusion The age of the study control group was higher than that of the experimental group, while DNA fragmentation index DFI was the opposite, which indicated that unexplained spontaneous abortion was closely related to the male sperm DFI, and the risk of miscarriage may increase with the increase of DFI.

Objective To explore the correlations between disease activity of inflammatory bowel disease(IBD) and lipid profiles levels by compare the levels of plasma lipids in patients with IBD. Methods A total of 159 IBD patients admitted to Nanhai Hospital of Southern Medical University from January 2013 to May 2018 were included in the study and the clinical data were collected. There were 159 healthy people recruited in the control group. The differences of plasma levels of triglycerides(TG), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), lipoprotein(a), albumin and high-sensitivity C-reactive protein(hCRP) between these two groups were analyzed respectively. The relationships between lipids levels and the severity of IBD were analyzed. Results Plasma levels of TG,TC,LDL-C,HDL-C and albumin were lower in IBD group than those in control group,but lipoprotein(a) was higher than control group(P＜0.05). The levels of TC,LDL-C,HDL-C and albumin were lower in CD patients compared to those of UC(P＜0.05). Plasma levels of TC,LDL-C,HDL-C gradually decreased with the severity of IBD. TC,LDL-C,HDL-C values were negatively correlated with hCRP levels in IBD patients. And lipoprotein(a) values was positively correlated with hCRP levels in IBD patient. However, there was no association between TG levels and the severity of IBD. Conclusion TG、TC、LDL-C、HDL-C levels are decreased and lipoprotein(a) is increased in IBD patients, especially CD patients, compared with healthy controls. Moreover, the cholesterol levels are negatively associated with more severe disease activity.

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2016—2018年度广州市单采血小板报废的主要原因,并探讨如何降低单采血小板报废率。方法 统计2016—2018年度广州市单采血小板的采集量、报废数量和报废率等相关数据,分析报废原因,提出相应改进措施。结果 2016—2018年广州血液中心单采血小板总报废率为1.13%,三年的报废率逐年下降。报废的最主要原因为血液感染因子筛查不合格或ALT异常,占总报废率64.44%;其次分别为血量不足(占比14.4%)、采血耗材/血袋/热合口漏(占比11.01%)等。结论 我中心单采血小板报废率虽逐年下降,但仍需加强献血前宣传,动员更多的健康适龄公民参加无偿献血,同时重视采前血液感染因子的筛查工作、采血前及采血过程的护理干预、设备维护保养和产品处理能力的培训,进一步有效降低血液报废率。

Objective To analyze the main causes of apheresis platelets discarding in Guangzhou from 2016 to 2018, and discuss how to reduce the discarding rate. Methods Collected the data of apheresis platelets collection, the discarding number and the discarding rate in Guangzhou from 2016 to 2018,to analysis the reasons of apheresis platelets discarding and introducing improvement measures. Results From 2016 to 2018, the total discarding rate of apheresis platelets collected from Guangzhou Blood Center was 1.13%. In the three years,the discarding rate declined year by year.The main reasons for apheresis platelets discarding were the result of blood infection factor test or ALT was not qualified, accounting for 64.44% of the total scrapping rate. Then followed by insufficient blood volume (14.4%) and Blood consumables/blood bags/heat closure leakage (11.01%). Conclusion Although the rate of apheresis platelet discarding in Guangzhou Blood Center is decreasing year by year, we still need to enhance blood donation propaganda, mobilize more healthy citizens to participate in blood donation, and pay attention to the screening of blood infection factors before blood collection, nursing blood donor before and during blood collection, and training of ability in equipment maintenance and product handling, so as to further effectively reduce the rate of blood discarding.

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.
