成都军区空军部队血吸虫病流行调查

目的调查成都军区空军部队血吸虫病流行情况,为制定血吸虫病防治措施提供依据。方法对驻疫区部队人员进行血吸虫循环抗原检测,确定感染者。对部队营区、训练场地、农场及油库采用系统抽样,结合环境抽样法进行钉螺普查。对有螺地段进行药物杀灭。结果共检查驻疫区人员4307人,查出感染者93人,人群血吸虫感染率为2.16%,以驻西昌、彭山、新津的部队感染率为高,分别达7.33%、1.22%、1.46%。重点人群为汽车驾驶员,占感染总人数的52.70%。重点单位是驻西昌某部,感染率达7.54%。来自疫区人员感染率为2.50%,非疫区人员感染率为1.99%。共查螺76.12×104m2,查出有螺面积2.1×104m2。解剖活螺662只,未查见阳性钉螺。有螺地段全部用氯硝柳胺灭螺。结论避免接触疫水,做好个人防护是做好血吸虫病防治工作的关键;加强重点地区、重点人群管控是降低血吸虫感染率的重要措施。重点地区是西昌一带,重点人群是汽车司机;及时查治感染者是防止发生慢性、晚期血吸虫病人的关键性措施;对来自疫区的人员要定期进行血吸虫感染检查;有螺地段要进行灭螺和环境整治,彻底消灭钉螺孳生场所。     

2010年湖南省洞庭湖流域武警部队血吸虫病疫情调查

目的掌握湖南省洞庭湖流域武警部队血吸虫病疫情,为制定有针对性的防治措施提供科学依据。方法从武警部队血吸虫病流行病学调查数据库和湖南省血吸虫病疫情数据库中,按分层整群的原则,在洞庭湖流域贯穿的常德、益阳和岳阳市随机抽取20余个执勤点和相对应的流行区、村为调查点,收集部队官兵及地方人群血吸虫病血清学特异性抗体水平（IgG）、年龄特征、工作性质特征和文化程度等进行分析比较。结果该地区武警部队官兵血吸虫病特异性抗体水平明显低于地方同龄人群（χ2=6.769,P〈0.05）;血吸虫感染与疫区生活时间长短、工作性质和文化程度等有关。结论驻洞庭湖血吸虫病流行区武警部队官兵存在血吸虫感染的高危因素,提高官兵对血吸虫病的防治的依从性和主动性是目前控制疫区部队人员感染的主要措施。

Glutamine supplementation in vitro and in vivo,in exercise and in immunodepression

In situations of stress, such as clinical trauma, starvation or prolonged, strenuous exercise, the concentration of glutamine in the blood is decreased, often substantially. In endurance athletes this decrease occurs concomitantly with relatively transient immunodepression. Glutamine is used as a fuel by some cells of the immune system. Provision of glutamine or a glutamine precursor, such as branched chain amino acids, has been seen to have a beneficial effect on gut function, on morbidity and mortality, and on some aspects of immune cell function in clinical studies. It has also been seen to decrease the self-reported incidence of illness in endurance athletes. So far, there is no firm evidence as to precisely which aspect of the immune system is affected by glutamine feeding during the transient immunodepression that occurs after prolonged, strenuous exercise. However, there is increasing evidence that neutrophils may be implicated. Other aspects of glutamine and glutamine supplementation are also addressed.     

Temporal changes in the oxidation state in in vitro blood

The rates at which the paramagnetic compounds deoxyhemoglobin (Hb) and methemoglobin (MHb) form in vivo within an area of hemorrhage are unknown. The present experiment establishes the baseline concentrations and rates of change in paramagnetic hemoglobin concentrations, as well as the pH in normal heparinized and clotted human blood maintained in vitro at 37 degrees C under anaerobic conditions over 30 hours. There was a moderate increase in Hb concentration in normal heparinized blood (average increase was 15.5%, rate = 0.50%/hour) and a slight increase in MHb concentration in the heparinized blood and clots (average increase was 1.4%, rate = 0.044%/hour). A second experiment was done to verify the activity of the RBC systems responsible for maintaining the hemoglobin molecule in the reduced state. Conversion of MHb to Hb in these samples proceeded at a rate of 5.6%/hour. In a third experiment, blood from 11 normal subjects maintained at 4 degrees C 25 degrees C was analyzed for MHb concentration over the course of 28 days. The level of MHb formation remained in the range of normal for at least 11 days in all subjects. The authors conclude that at basal conditions created in vitro, the blood levels of both Hb and MHb remain at relatively low levels. Therefore, if the accumulation of Hb and/or MHb occurs in acute in vivo hematomas it must be driven by intrinsic tissue factors.     

Carcinoma in situ in cryptorchid testes in post-pubertal patients]

The pathohistologic analysis of testis sections of 37 postpuberty patients with different types of cryptorchism is performed. The tissue samples were taken during orchiopehy, fixed in Bouin's solution and treated by the standard histologic techniques. The morphologic criteria are presented for identification of the presence of the so called carcinoma in situ cells found in two cases. Besides, in 13 patients rare, mainly single, atypical germinative cells were found in a smaller number of the seminiferous tubules. It has been concluded that the presence of carcinoma in situ cells in undescended testes of some patients and considering the simple way of sampling, lack of complications and high reliability of the diagnostic procedure, it is absolutely justified to take routine biopsy of testes during orchiopexy in each postpuberty and perhaps prepuberty patient.
