RESUMEN
Objective To investigate the nursing of sedation and analgesia using low-dose fentanyl with midazolam during intra-arterial treatment with mechanical thrombectomy by means of stent for patients with anterior-circulation acute ischemic stroke.Methods All of 61 patients who underwent intra-arterial treatment with anterior-circulation acute ischemic stroke were retrospectively collected.They were divided into two groups according to the different program of individual conscious sedation:the control group(30 cases)used midazolam for intravenous maintain sedation,experimental group(31 cases)added the low-dose fentanyl on the basis of the control group.The thrombectomy was performed by the same group of interventional radiologists,while the effect of sedative,vital signs,respiratory curve and SpO2(blood oxygen saturation),assessment of Ramsay's sedation score,restlessness and other sedation adverse reactions were respectively observed in both groups.Nursing intervention was performed aiming at different states of patients during operation.Results All 61 patients were implemented with good medical care with no intracranial hemorrhage or intraoperative death.In the control group,there were 4 patients with Ramsay 1 point of sedation,resulted motion artifacts in digital subtraction angiography images in 3 of them,1 patient with slight reduction of SpO2,and vomiting in 4 patients.1 patient with decreased mean arterial pressure.In the experimental group,there was no Ramsay 1 point of sedative patient.The SpO2 was decreased in 5 patients.Respiratory inhibition occurred in 3 patients and the mean arterial pressure decreased slightly in the other 3 patients.Conclusions Application of low-dose fentanyl and midazolam is safe and reliable in patients who underwent intra-arterial treatment with anterior-circulation acute ischemic stroke.While closely observation to the changes of breath frequency curve and SpO2 in operation are very essential to actively prevent the occurrence of respiratory depression.
RESUMEN
Objective:To explore the relationship between Tongren analysis EV 71 intestinal virus genotyping and humoral immune function ,for further clinical understanding of enterovirus EV 71 provide references.Methods:February to August 2014 Tongren to our hospital for treatment of intestinal virus EV 71 HFMD infected children ,according to the genetic type of virus infection is mainly divided into three groups ,namely group A,there were A type of intestinal virus EV 71 infection,20 patients;group B,there were B-type intestinal virus EV71 infection,20 patients;group C,there were C-type intestinal virus EV71 infection,20 cases of children.Three groups of patients by detecting immunoglobulin levels and TNF-ɑ, IL-6 and IL-10 levels, and to compare different genotypes affect intestinal virus EV71 HFMD children humoral immune function.Results:After testing,A group of patients with TNF-ɑ,IL-6 and IL-10 levels were (285.60 ±30.50) pg/L,(60.50 ±5.60) pg/L,(25.50 ±4.50) pg/L,than those in group B,high levels of three indicators of group C patients ,a significant difference ( P0.05 ) .Conclusion:Different genotypes of enterovirus EV 71 can cause serious foot and mouth disease ,and could significantly improve the level of serum immunoglobulin levels of inflammatory cytokines ,but the intensity of different genotypes of different pathogenic ,there are some differences ,but the specific mechanisms need to be further explored.

Objective To investigate the methods and internal quality control ( IQC ) leucorrhea routine examinationin clinical laboratories of medical institutions in Guizhou Province.Methods In 2009, 97 clinical laboratories were randomly selected for the first investigation.At the same time, staffs in theinvestigated laboratories were educated on the importance of IQC.The second investigation of the same items was carried out in 2011 inthe same laboratories.The results of the two investigations were analyzed byChi-square test.Results 2009 and 2011 numbers of laboratories thoseonly used normal saline suspension method for leucorrhea examination were 17and 16 (χ2 =0.037, P >0.05 ) respectively, used bothnormal saline and 10%KOH suspension methodswere 16and 2(χ2 =12.003,P<0.01), used staining method were 64and 79(χ2 =5.488,P<0.05), both used suspension and staining methods were 60and 73(χ2 =4.041, P<0.05), used normal salinesuspension method combined with Wright stain and Gram staining methods were3and 28(χ2 =23.996,P<0.01) respectively.Numbers of Laboratoriespracticing IQC were 2and 88in 2009 and 2011 respectivly(χ2 =153.293,P <0.01).Conclusions Currently, the most common used method for leucorrhea routine examination is suspension.Through the investigations and education, the quality ofleucorrhea routine examination was improved in Guizhou Province.
RESUMEN
Objective:To investigate the effects of TGF-β1 on T lymphocytes of BALB/c mice infected with Echinococcus granulosus( E.granulosus ) in vitro.Methods: The inhibitor group:the spleen cells of BALB/c mouse were co-cultured with E.granulosus and SB525334.The control group:the spleen cells of BALB/c mouse were co-cultured with E.granulosus and PBS.The blank group:the spleen cells of BALB/c mouse were co-cultured with RPMI-1640 medium and SB525334.The lymphocytes were collected at 48 h post-infection.The T lymphocyte subsets, the number of CD4+CD25+T cells, the number of NK cells, and the expression of NKG2D receptor were detected by flow cytometry.The NK cell activity was determined with the lactate dehydrogenase leakage assay(LDH).Results:The inhibition the TGF-β1 receptors resulted in the increase of in the number of CD4+T cells,the decrease in the number of CD8+T cells,the increase of in the ratio CD4+/CD8+T cells,the decrease of in the number of CD4+CD25+T cells,the increase in the expression of the NKG2D receptors,the increase in the lysis rate of Yac-1 cells by NK cells,and a positive cor-relation between the expression of activity receptor NKG2D and killing activity of NK, which were mediated by E.granulosus.Conclusion: The inhibition of TGF-β1 receptors can enhance the immune response of T lymphocytes against E.granulosus infection in vitro.
