Lymph node pick up by separate stations: Option or necessity

AIM: To evaluate whether lymph node pick up by separate stations could be an indicator of patients submitted to appropriate surgical treatment. METHODS: One thousand two hundred and three consecutive gastric cancer patients submitted to radical resection in 7 general hospitals and for whom no information was available on the extension of lymphatic dissection were included in this retrospective study. RESULTS: Patients were divided into 2 groups: group A, where the stomach specimen was directly formalinfixed and sent to the pathologist, and group B, where lymph nodes were picked up after surgery and fixed for separate stations. Sixty-two point three percent of group A patients showed 16 retrieved lymph nodes compared to 19.4% of group B(P 0.0001). Group B(separate stations) patients had significantly higher survival rates than those in group A [46.1 mo(95%CI: 36.5-56.0) vs 27.7 mo(95%CI: 21.3-31.9); P = 0.0001], independently of T or N stage. In multivariate analysis, group A also showed a higher risk of death than group B(HR = 1.24; 95%CI: 1.05-1.46).CONCLUSION: Separate lymphatic station dissection increases the number of retrieved nodes, leads to better tumor staging, and permits verification of the surgical dissection. The number of dissected stations could potentially be used as an index to evaluate the quality of treatment received.     

移动护士工作站对提高儿科门诊输液室护理质量的效果分析

目的探讨移动护士工作站对某三级甲等医院儿科门诊输液室护理质量的影响。方法对某三级甲等医院儿科门诊输液室25位护士以及450位患儿家属进行问卷调查。结果 90.1%的护士认为移动护士工作站提高了她们在核对、处理医嘱,查询患儿检查结果以及与患儿家属沟通效果等3方面的效率;患儿家属对护理态度、响铃应答以及等待就诊时间满意度均明显高于移动护士工作站实施前;同时,移动护士工作站还优化了护理工作流程,减少了每月的护理差错和护理投诉事件,同时也缩短了患儿每次就诊输液等待时间。结论移动护士工作站的实施,不仅优化了儿科门诊输液室的护理工作流程,而且还提高了护理质量,和谐了护患关系,值得在临床护理工作中推广。     

南水北调东线江都泵站钉螺扩散情况现场观察

目的了解南水北调东线取水口抽调江水时钉螺能否进入输水河道孳生扩散。方法对泵站前水源河道、泵站拦污栅、泵站消力池滩地和渠首输水河道进行钉螺分布调查,采用打捞的方法检测水源河道漂浮物携带钉螺情况,结合水工建筑功能、调水量及有关河道水位资料,对钉螺通过泵站扩散可能性进行分析研究。结果江都泵站前水源河道查出钉螺面积185.28hm2,水源河道漂浮物调查发现钉螺主要在汛期吸附于漂浮物漂流扩散;泵站前拦污栅及泵站出水口消力池滩地及泵站后渠首输水河道均未发现钉螺。结论南水北调东线调水泵站水闸、拦污栅、水泵、消力池等水工建筑物具有阻挡、沉淀钉螺的作用,泵站消力池及输水河道因水体大,常年保持高水位运行,不适宜钉螺孳生。     

NASA空间站航天员病症目录分析

目的对NASA空间站病症目录进行分析,为我国空间站医学保障设计和资源配置提供参考。方法对NASA空间探索任务病症清单(space medicine exploration medical condition list,SMEMCL)中的空间站病症进行应对优先情况汇总,并按照相应的标准进行分类及分级处理。结果按照应对优先等级划分,必须处理和酌情处理的病症占绝大多数(82.76%),属于不专项应对病症仅占很少部分。在对病症进行分类及分级后,可见分类中以临床病症占比例最大(82.72%);按照NASA病症分级标准(严重程度分级),属于轻中程度的病症最多(91.36%),极少部分属于严重病症。结论 NASA空间站病症目录详实全面,必须处理和酌情处理的轻中程度临床病症居多;在进行空间站航天员医学保障的设计和相关医学资源的配置时应重点考虑这部分病症,对其余病症适当兼顾。

Integrative study of cell damage and cancer risk in gas station attendants

Gas station attendants are potentially exposed to carcinogenic substances. This study aimed to evaluate chronic occupational exposed gas station attendant’s according to genetic parameters and its relationship with cancer predisposition. Forty gas station attendants were recruited and paired with 40 control subjects. Thousand cells from each subject were analyzed counting the number of pyknotic (PYC), karyolitic (KYL), karyorrhetic (KHC), condensed chromatin (CC), binucleated (BN), basal cells (BC), Nuclear buds (Nbud), and differentiated cells (DIFF). More 2.000 differentiated cells were analyzed counting micronucleated (MNi) and nuclear buds (NBud). We observed a statistical increase in BC and decrease in DIFF (p < 0.05). PYC, CC, KYL, MN, NBud were statistically increased (p < 0.05). All in all, our data showed elevated DNA damage, chromosomal instability, and cell cycle disturbing in our group of gas station attendants. It is a clear risk for their health in future and could be classified as a cancer predisposition.
