RESUMO
Objective:To study the incidences of vitamin K 1 and K 2 deficiency (VKD) in umbilical cord blood (UBC) of neonates and the dynamic changes and influencing factors of serum vitamin K 1 levels after preventive vitamin K 1 supplementation. Methods:From January 2021 to June 2022, neonates born in the Obstetrics Department of our hospital were prospectively enrolled and the levels of vitamin K 1 and K 2 in UBC and serum vitamin K 1 levels at 14 d and 28 d after vitamin K 1 supplementation were measured. The neonates were assigned into hospitalization group and healthy group and further assigned into early-preterm, late-preterm and full-term groups based on gestational age (GA). The incidences of VKD of different GA were studied. Dynamic changes of vitamin K 1 levels were calculated. Multivariate logistic regression was used to analyze the influencing factors of vitamin K 1 levels in hospitalization group at 28 d. Results:A total of 100 neonates were included. 80 neonates were hospitalized, including 25 early-preterm, 25 late-preterm and 30 full-term. 20 were healthy full-term neonates. No significant differences existed in the incidences of VKD of different GA ( P>0.05), however, the overall incidences were high (82.0% and 84.0%, respectively). After preventive vitamin K 1 supplementation, the levels of vitamin K 1 in full-term and preterm groups at 14 d were higher than at birth and 28 d. The levels of vitamin K 1 in hospitalized full-term neonates at 14 d and 28 d were higher than hospitalized preterm neonates. The levels of vitamin K 1 at 28 d in healthy group was significantly higher than hospitalization group ( P<0.05). Multivariate logistic regression analysis showed that maternal complications during pregnancy ( OR=5.889, 95% CI 1.621-21.399, P=0.007) and neonatal antibiotic use ( OR=5.615, 95% CI 1.833-17.221, P=0.003) were risk factors and formula feeding ( OR=0.389, 95% CI 0.193-0.786, P=0.008) was a protective factor for VKD. Conclusions:VKD is common in neonates. The serum vitamin K 1 level increases significantly after preventive vitamin K 1 supplementation. The vitamin K 1 levels of hospitalized full-term neonates at 14 d and 28 d are higher than hospitalized preterm neonates. The levels of vitamin K 1 at 28 d in hospitalized neonates are influenced by feeding methods, maternal complications during pregnancy and neonatal antibiotic use.
RESUMO
Objective To investigate the relationship between body composition and adequacy of dialysis,and analyze the related risk factors for inadequate delivery of hemodialysis.Methods In a prospective clinical trial,two different methods determining dialysis dose were simultaneously applied:Kt/Vdau (conventional method with Daugirdas' formula) and Kt/Vbem [online clearance monitoring (OCM) measurement with Ⅴ measured by body composition monitor (BCM)].Using the value of 1.27 as the boundary,the patients were divided into two groups:Kt/Vbcm ＜ 1.27 group and Kt/Vbcm≥ 1.27 group.Clinical indices were compared between the two groups.Multiple linear regression was applied to analyze the potential impact factors of the difference between Kt/V values calculated by the two methods.Receiver operator characteristic (ROC) curve was applied to analyze meaningful factors.Results A total of 138 maintenance hemodialysis patients with age of (54.9±12.7) years old were enrolled,and 55.1％ of them were males.There was no significant difference between Kt/Vdau and Kt/Vbcm [1.432(1.235,1.718) vs 1.434 (1.244,1.642),P=0.823].Kt/Vdau was incidentally prone to falsely high values due to operative errors,whereas in these cases OCM-based measurement Kt/Vbcm delivered realistic values.An excellent correlation was observed between Kt/Vdau and Kt/Vbcm;the mean difference was 0.07,95％CI (-0.66-0.79);the correlation coefficient was 0.842(0.821-0.862).The patients in Kt/Vbcm≥ 1.27 group had older age,lower body mass index (BMI),lower height and weight,lower total body water (TBW),lower extracellular water,lower intracellular water,and lower lean tissue index (LTI) compared to those in Kt/Vbcm ＜ 1.27 group.Excellent correlations were observed between Kt/Vbcm and TBW or LTI (r=-0.834,P ＜ 0.001;r=-0.721,P ＜ 0.001).ROC curve analysis showed that the sensitivity and specificity of predicting inadequate delivery of hemodialysis were 87.1％ and 86.5％,with a threshold of 30 L for TBW.It also showed that the sensitivity and specificity of predicting inadequate delivery of hemodialysis were 60.4％ and 94.6％,with a threshold of 11.05 kg/m2 for LTI.Conclusions BCM can give more accurate parameters of urea distribution volume,thus modifying the result of Kt/V.TBW and LTI are important risk influencing factors for inadequately dialysis,and special attention should be paid to patients with TBW ＞ 30 L or LTI ＞ 11.05 kg/m2.

RESUMO
The ensemble empirical mode decomposition (EEMD) can be used to overcome the mode mixing problem of empirical mode decomposition (EMD) effectively. The EEMD method and Hilbert-Huang Transform (HHT) can be used to analyze pulse signals of Traditional Chinese Medicine (TCM). The amplitudes of the added white noise were about 0.1 and 0.2 time standard deviation of the investigated signal respectively. The difference of average frequency and average energy of every mode between normal pulse, slippery pulse, wiry pulse and wiry-slippery pulse were demonstrated based on different amplitudes of the added white noise. The results showed that it is more in line with clinical practice when the amplitude of the added white noise is about 0.2 time standard deviation of the investigated signal.

Abstract: In this paper, factors contributing to the formation of pulse wave were analyzed based on hemodynamic principles. It is considered that formation of pulse wave was related to its propagation and reflection characteristics. Propagation of the pulse wave was characterized by pulse wave velocity, and reflection of the pulse wave was characterized by reflection coefficient. Pulse wave velocity and reflection coefficient were proposed as the eigenvectors of pulse wave in pulse diagnosis of traditional Chinese medicine, and support vector machine (SVM) was used to recognize slippery pulse, stringy pulse and plain pulse. Pulse wave velocity and reflection coefficient of the slippery, stringy and plain pulses in healthy people were calculated in this study, and SVM with Gaussian radial basis function was used for classifying. Results showed that pulse wave velocity and reflection coefficient with physiological and pathological significance had advantages in distinguishing slippery pulse, stringy pulse and plain pulse, which offered a new idea for recognizing pulse condition.
