ABSTRACT
Objective:To investigate the effect of the 3t sensorial saturation in the application of relieving pain and comfort due to femoral vein blood sampling in preterm infants, so as to provide the reference for the selection of clinical nursing plans.Methods:This was a quasi experimental study. A total of 110 preterm infants admitted to the neonatal unit of Shanxi Children′s Hospital from August 2021 to March 2022 were selected and divided into the control group and intervention group with 52 cases respectively by the random number table method. The control group implemented conventional care, and the intervention group implemented the 3t sensorial saturation method including taste, touch and talk on the basis of the control group. The pain and comfort of two groups were evaluated by the Premature Infant Pain Profile (PIPP) and COMFORTneo Scale at 3 min before, during, and 3 min after blood, and the heart rate and SpO 2 of the two groups were compared. Results:Finally, 52 premature infants were included in both groups. The PIPP score, the total score of the COMFORTneo Scale, the heart rate and SpO 2 were 2.00 (1.00, 3.00), 6.50 (6.00, 7.75), 4.00 (3.00, 5.00), 7.00 (6.00, 8.00), 17.00 (15.00, 19.00), 9.50 (9.00, 10.00) points, (137.29 ± 8.58), (148.31 ± 8.89), (143.06 ± 7.61) times/min, 0.980 (0.970, 0.990), 0.960 (0.950, 0.970), 0.980 (0.970, 0.990) in the intervention group, 2.00 (1.25, 3.00), 12.00 (11.00, 13.00), 7.00 (6.00, 8.00), 7.00 (6.00, 9.00), 25.00 (23.00, 27.00), 20.00 (19.00, 22.00) points, (141.54 ± 10.57), (179.71 ± 14.62), (162.00 ± 14.32) times/min, 0.980 (0.960, 0.990), 0.940 (0.920, 0.958), 0.960 (0.940, 0.978). The results of generalized estimating equation analysis showed that the PIPP score, total COMFORTneo Scale score and SpO 2 via different time points, subgroups, and subgroups with time points were statistically significant (Wald χ2 values were 16.72-2 489.71, all P<0.05). The results of two-factor repeated measures ANOVA showed that the interaction effects of heart rate via different time points, subgroups, and subgroups with time points were statistically significant ( F=253.08, 105.02, 77.17, all P<0.05). Conclusions:The 3t sensorial saturation method can effectively reduce pain during femoral vein blood sampling in preterm infants, can improve the comfort level of preterm infants, is conducive to the stabilization of vital signs in preterm infants, and is suitable for promotion and application in clinical care.
ABSTRACT
Objective:To investigate the predictive value of portal vein (PoV) blood circulating tumor cells (CTCs) count in patients with pancreatic cancer on the postoperative prognosis.Methods:The data of 58 patients receiving radical resection of pancreatic cancer and PoV CTCs detection at People's Hospital of Zhengzhou University from Aug 2018 to Jun 2020 were collected. According to the cut-off value of PoV CTCs>10/5 ml made by receiver operating characteristic curve (ROC), patients were divided into high CTCs group and low CTCs group and the differences in clinicopathological parameters and prognosis of the two groups were compared.Results:Postoperative progression-free survival rate of the low CTCs group was higher than that of the high CTCs group ( χ 2=12.97, P<0.001).Univariate COX regression analysis showed that tumor diameter >4 cm, lymph node invasion, TNM staging, CTCs>10/5 ml, postoperative CA199>37 U/m were risk factors for postoperative prognosis. Multivariate COX regression analysis demonstrated that TNM stage ( OR=2.782, P=0.024), CTCs count >10/5 ml ( OR=2.583, P=0.047), postoperative CA199>37 U/m ( OR=3.775, P=0.004) were the independent risk factors of prognosis. Conclusion:A higher PoV CTCs count was a risk factor for poor prognosis of patients with pancreatic cancer after radical resection.

ABSTRACT
Objective:To compare the results of three kinds of glucometers and automatic biochemistry analyzer for the detection of blood glucose level of finger capillary and vein blood, and adopt linear regression to analyze their relationship.Methods: 204 patients with or without diabetes were enrolled in this study. Their finger capillary and vein blood were detected by three kinds of glucose meters and automatic biochemistry analyzer, respectively. And these data were analyzed by using linear regression and pair-t-test.Results: The comparative results revealed that the order of correlation between every glucose meters with automatic biochemistry analyzer was Accuchek higher than GT-1920 and GT-1920 higher than One Touch when the range of hematocrit (Hct) value was in 35.1%-51.6%. The correlation of Hct between every glucose meter and automatic biochemistry analyzer when the range of Hct was 25.0%-35.0% was significant higher than that when the range was 35.1%-51.6% (t=2.19,P<0.05). For finger capillary blood, the bias of One Touch was largest, while for vein blood, the bias of GT-1920 and One Touch were better. Besides, the detected results of blood glucose both of GT-1920 and One Touch were significantly higher than automatic biochemistry analyzer(t=2.34,P<0.05).Conclusion: There were better correlation between every glucose meter and automatic biochemistry analyzer, respectively, and the correlations between them can be effected by Hct. While there were still certainly difference between them.
ABSTRACT
Objective To analyze the concentration changes of insulin and c peptide of in portal vein and peripheral blood, and explore the feasibility of using insulin and c peptide concentration changes in assessment of liver function. Methods The portal vein and peripheral blood samples were extracted from 82 clinical liver cancer patients, and the insulin and c peptide concentration were detected. The differences in the insulin and c peptide concentration in portal vein and peripheral blood were statistically analyzed. Results The insulin concentration in the portal vein and peripheral blood values were 32.43 μ U/ml and 8.05 μ U/ml, respectively, there was a significant difference (P0.05) . Conclusion Liver metabolizes insulin as the target organ of insulin, while c-peptide dose not be metabolized in vivo, so it is possible to assess liver function by comparative analysis of the metabolic rate of insulin and c-peptide changes.
ABSTRACT
Objective:To study the influence of hematocrit on the consistency between blood glucose meters and automatic biochemical analyzer for testing blood glucose of peripheral blood and venous blood.Methods: 200 cases of diabetic and non-diabetic patients were selected in our hospital from January 2013 to September 2015, in which 124 cases were diabetics and 76 cases were non-diabetics. All the selected patients were treated with venous blood and peripheral blood glucose testing by the SIEMENS ADVIA1800 full automatic biochemical analyzer and three brand of blood glucose meters (Reiter GM300, Arkray GT-1920, Johnson & Johnson One Touch), comparing their consistency.Results: The hematocrit range was 35.1~51.6%, accounted for 91.0%(182), 25.0~35.0% of patients accounted for 9.0%(18), and average hematocrit was (42.3±4.2). When hematocrit was 35.1~51.6%, the correlation of automatic biochemical analyzer and Reiter GM300 blood glucose meter was high and stable, followed by Arkray GT-1920 and Johnson &Johnson One Touch. When hematocrit was 25.0~35.0%, the correlation of automatic biochemical analyzer and three blood glucose meters were high than hematocrit was 35.1~51.6%. There was no significant difference between SIEMENS ADVIA1800 automatic biochemical analyzer and Reiter GM300 about monitoring the blood glucose results, but there were significant differences between Johnson and Johnson One Touch and Arkray GT-1920.Conclusion: The automatic biochemical analyzer and three blood glucose meters have good correlation. When hematocrit is greater than 35%, the correlation is lower; when hematocrit is less than 35%, the correlation increases.
ABSTRACT
Objective To observe the change of cerebral oxygen metablism and the level of blood lactate in early stage of sepsis in rats.Method Sixty-four SD rats were randomly(random number)divided into septic group and control group.The sepsis model of rat was made by lipopolysaccharide (LPS,10 mg/kg)injected intra-abdominally,and rats of control group were treated with the same amount of physiological saline instead.And each group was further divided into 4 sub-groups of4 h,6 h,12 h and 24 h after treatment.At each interval,blood samples were obtained via jugular vein for detecting blood oxygen saturation (Sjv02)and blood lactate(LA).The blood oxygen saturation(Sa02)of ventral aorta was also measured.Arteriovenous oxygen content difference (AVD02) and oxygen extraction fraction (OEF) were studied.These four variables were analyzed and compared between two groups.Results The AVD02 and OEF in sepsis group were higher than those in control groups of 3 h,6 h and 12 h (P0.05).LA in sepsis group was higher than that in control group in each interval (P<0.05).Conclusions In early stage of sepsis,cerebral perfusion,cerebral oxygen supply and cerebral oxygen extraction increase.The global oxygen metabolic variables(Sjv02,AVD02 and OEF)and the level of LA can be used to objectively and accurately evaluate the cerebral oxygen metabolic dysfunction in early stage of sepsis.
ABSTRACT
Objective To investigate the relations between the portal parameters of homodynamic and stages of liver fibrosis of chronic hepatic B patients.Methods Fibrosis parameters of blood serum of one hundred and two patients with chronic viral hepatic B were measured with Doppler ultrasonic technique.The inner diameters,blood flow velocity,blood flow volume of their portal veins were investigated.And,the pathological changes of liver tissues were examined.Results The blood flow velocity of portal vein correlates very well with the stages of liver fibrosis,and reduces with the development of the degree of liver fibrosis.The blood flow velocity of severe fibrosis patients is obviously smaller than that of mild patients,and is 28.4% slower compared stage 4 with stage 1(P
