Analysis of abnormal detectable rates for blood test indexes before and after treatment of snake bite / 国际检验医学杂志

Objective To analyze the abnormal detectable rates of different kinds of blood test indexes before and after treatment in the patients with snake bite and to probe into the change condition of these indexes after different snake bite .Methods The inpa‐tients with clearly diagnosed what kind of snake bite in the past two years were selected as the research subjects .The multiple blood test indexes were determined before and after treatment in these patients .The abnormal detectable rates of these indexes were ana‐lyzed and compared among various snake bite patients .Results The different kinds of snake bite all could cause the different de‐grees of changes in some detection indexes among partial patients .Specially ,the detectable rates of WBC ,PT ,APTT ,TT ,D‐D ,CK , CK‐MB ,LDH ,Urea ,Cr and Cys‐C increase and PLT and Fbg decrease caused by viper bite were apparently higher than those caused by other kinds of snake bites (P<0 .05) .The detectable rates of CO2 increase and K+ decrease in the coral snake bite were apparently higher than those in trimeresurus gramineus ,cobra and viper bite (P<0 .05) .Conclusion Because the snake species and toxicities are different in the various snake bites ,so the caused changes and the abnormal detectable rates of blood test indexes also are different .

Detectable rate and correlative factors of behavior problems among Hui nationality left-behind children in rural district of Ningxia / 中华行为医学与脑科学杂志

Objective To investigate the detectable rate and correlative factors of behavior problems among Hui nationality left-behind children in Ningxia rural area.Methods 1394 children,between 6 and 15 years old,of which 282 were Hui nationality children and 112 were Hui left-behind children,were selected from six primary schools and two junior middle schools using cluster random sampling method in Yongning,Ningxia.All of them were assessed by the Achenbach 's Child Behavior Checklist (CBCL) and self-designed General Information Questionnaire.Logistic regression method was used to analyze the correlative factors of behavior problems.Results The detectable rate of behavior problems among Hui nationality children between 6 and 15 years old was 31.25％,which was higher than the Han nationality left-behind children' s(17.84％) and Hui nationality nonleft-behind children' s (14.12％).Among the Hui left-behind children,those who between 6 and 11 years old,had been left alone between 5 and 7,and whose parents exchanging ideas with teachers less than one time a month had higher detectable rates (x2 =14.904,6.327,7.904,P ＜ 0.05).Among the Hui ethnic children,the detectable rates of those who between 6 and 11 yeas old were higher than that of the non-left-behind children' s(P ＜ 0.05).Logistic regression analysis showed that Hui ethnic left-behind children between 12 and 15 years old (OR =0.179) and those whose parents contacted with their teachers frequently(OR =0.362) had less possibilities to attach behavior problems.Conclusion The detectable rate of behavior problems among Hui nationality left-behind Children between 6 andl5 years old in Ningxia is higher,and the correlative factors are complex.

Detection rate of post-traumatic stress disorder symptoms among military rescuers in Wenchuan earthquake and its interventional factors / 军事医学

Objective To investigate the positive detectable rate of post-traumatic stress disorder ( PTSD ) and its influencing factors among the military rescuers , and explore preventive measures for rescuers .Method At three points , 2600 soldiers from Wenchuan military rescuers were enrolled , whose PTSD symptoms were evaluated by PCL-S.Self-edited questionnaires on the general state , Alerting Test Questionnaires for Military Group Stress ( ATQMGS ) , and State-Trait Anxiety Inventory(STAI)were used to evaluate the influencing factors of rescuers′PTSD symptoms.Results Seventy-one rescuers were tested positive for PTSD and the positive detectable rate was 2.9%.On the basis of demographic data , the difference test suggested that rescuers different in terms of positions , duration of rescue, family structure, trauma history, mental problem history or trauma history during the rescue were significantly differenct in PTSD symptoms , which were strongly and positively correlated with anxiety , morale, and self-efficacy, but were strongly and negatively correlated with leadership support , control feeling , promotion motivation , cognition of tasks , sense of belonging and work value .Multiple linear regression showed that the influencing factors of PTSD symptoms included the trait of anxiety , leadership support , trauma history, control feeling, mental problem history, trauma history during the rescue, position and duration of rescue. Conclusion The PTSD positive detectable rates among the military rescuers are lower than in the previous research.PTSD symptoms of military rescuers are related to such factors as the position , duration of rescue , family structure , trauma histo ry, mental problem history, trauma history during the rescue, trait of anxiety, morale, self -efficacy, leadership support, control feeling , promotion motivation , cognition of tasks , sense of belonging and work value .The influencing factors of PTSD symptoms are the trait of anxiety , leadership support, trauma history, control feeling, mental problem history, trau-ma history during the rescue , position level and rescue duration .

STUDY OF DETECTABLE RATE OF FREE CANCER CELLS OF PATIENTS WITH GASTRIC CANCER / 解放军医学杂志

Through the qualitative study of peritoneal cavity free cancer cells of patients with gastric cancer, to evaluate the rational of exercising intraoperative no touch isolation technique, routine peritoneal and warm perfusion chemotherapy after the operation. 102 patients in PLA 309 Hospital with gastric cancer were included into the study. 100 ml peritoneal fluid were collected respectively before the investigation and before close peritoneal cavity,and rapidly sent for free cancer cells examination. Results: Before the investigation, the positive rate of free cancer cells is 36.3%, and the positive rate before close peritoneal cavity is 52.9%. The free cancer cells positive rate is concerned with tumor infiltration depth, serous membrane infection area and the type of the histopathology。Conclusions: Inside the peritoneal cavity of patients with gastric cancer, free cancer cells are able to survive and have a high degree of activity. Although all kinds of intraoperative no touch isolation technique are used, it still cannot be avoided that some cancer cells will exfoliate and slip into the peritoneal cavity. The wound stimulation during the operation will certainly increase the exfoliation. So, it is quite necessary in the course of operation to adopt no touch isolation technique and to use a great deal of normal saline to give peritoneal cavity lavage. And what's more important is, to give these patients who show positive in the free cancer cell examination perfusion chemotherapy after the operation.
