Abstract： Objective: To explore the clinical effect of tumescent technique in early operation of massively burned patients. Methods: A retrospective cohort study was conducted on 27 patients with large area burns accorded with the inclusive criteria and admitted from June 2019 to November 2022. Among them, 14 patients admitted from June 2021 to November 2022 were treated with intraoperative injection of tumescent fluid for hemostasis and were rolled in tumescent group, or observation group; 13 patients admitted from January 2019 to November 2021 were treated with tourniquet for hemostasis were rolled in tourniquet group, or control group. The operation time, blood loss, blood preparation, blood transfusion, preoperative and postoperative hemoglobin, intraoperative and postoperative blood pressure, heart rate, postoperative skin graft survival rate and other related indicators were compared between the two groups, and the clinical effects were observed. Results: There was no statistical difference in preoperative blood volume between the two groups (p > 0.05). The actual amount of blood transfusion in the observation group was less than that in the control group, and the difference was statistically significant (p < 0.05). The intraoperative blood loss and operation time in the observation group were significantly less than those in the control group, and the difference was statistically significant (P < 0.05). There was no statistical difference in preoperative and postoperative hemoglobin between the two groups (p > 0.05). The survival rate of skin grafting in the observation group were slightly higher than those in the control group, and the difference was statistically significant (P < 0.05). The vital signs of patients in the observation group were more stable than those in the control group, and the difference was statistically significant (P < 0.05). Conclusion: Tumescent technique can reduce the amount of intraoperative blood loss, shorten the operation time, improve the survival rate of postoperative skin grafting, and ensure the stability of intraoperative hemodynamics in early operation of massively burned patients.

Abstract：
Background De Ritis ratio is a new indicator to evaluate the prognosis of severe patients in recent years. At present, De Ritis ratio can only be used to evaluate the prognosis of adult HLH, while there is no relevant study on children HLH. Objective To analyze the relationship between De Ritis ratio and clinical features of children with HLH and its prognostic significance, so as to provide a theoretical basis for early clinical identification and diagnosis of HLH. Method A total of 218 children HLH patients hospitalized in The Guizhou Children's Hospital from January 2013 to May 2022 were enrolled. Based on the De Ritis ratio (AST/ALT). The subjects were divided into T1 group (De Ritis ratio ≤ 1.57)、T2group (De Ritis ratio 1.57< T2< 3.22) and T3 group (De Ritis ratio ≥3.22). Analyzing the relationship between the difference of clinical characteristics and prognosis of the three groups, the correlation between De Ritis ratio and clinical characteristics and the risk factors affecting poor prognosis through Cox regression. Results The T3 group had higher the proportion of PICU, respiratory failure, central nervous system damage and shock, higher mortality, higher CK-MB, LDH, APTT and SF levels and lower ALB and FIB levels than T1 and T2 group. In terms of treatment, the proportion of children who use blood purification in the T2 and T3 groups was significantly higher than that in the T1 group. Correlation analysis showed that the De Ritis ratio was positively correlated with the levels of ANC, CRP, TBIL, CK, CK-MB, LDH, APTT and SF, but was negatively correlated with the levels of ALB, FIB, Ca2+ and Na+. Univariate analysis showed that treatment in PICU, respiratory failure, shock, dysfunction of central nervous system, PLT< 100 ×109/L, Na+ ≤ 130 mmol/L, ALB ≤ 30 g/L, CK-MB ≥ 40.5 U/L, LDH ≥ 927.5 U/L, APTT ≥ 53.95s, FIB ≤1.45 g/L and SF ≥ 1897 μg/L were the risk factors affecting the prognosis of children (P < 0.05); Multivariate analysis shows that respiratory failure (HR = 6.41, 95% CI = 2.24，18.30), ALB ≤ 30 g/L (OR = 3.13, 95% CI = 1.17, 8.41) and FIB ≤1.45 g/L (OR = 5.18, 95% CI = 1.68, 15.9) were risk factors affecting the prognosis of children (P < 0.05). Survival analysis showed that there was the OS of T3 group and T2 group was lower than that of T1 group (P =0.001; P=0.038), and there was no significant difference between T3 group and T2 group (P >0.05). Conclusion Children with high De Ritis ratios who have HLH have a worse prognosis. For the prognosis of HLH children, it is crucial to pay attention to the early changes in the De Ritis ratio.

Abstract： In order to reveal the morphological differences between pin and thrum flower development of Common buckwheat. The mega- and microsporogenesis and development of female and male gametophytes in pin and thrum flower of Fagopyrum esculentum were investigated by using the paraffin section method. The results were as follows: The cytological characteristics of pistil and stamen development of pin and thrum flowers show highly similar. Both type flowers have orthotropous ovule, inner and outer integument, and thickly nucellus. Moreover, the megaspore mother cells undergo meiosis divides into linear type tetrads, and the one in the chalazal end is functional, which suggested that their development of embryo sac belongs to Polygonum type. The anther has four chambers and the anther wall is composed of epidermis, endothecium, one layer of middle layer and glandular tapetum. In addition, meiosis of microspore mother cell is followed by simultaneous cytokinesis and results in common tetrahedral tetrads. Furthermore, most of tetrads are tetrahedral, but a small number of decussate tetrads are also observed in thrum flower. Most of mature pollen grains are 2-cell type, and 3-cell type pollen grains are also observed in pin and thrum flower. Comparing the pistil and stamen developmental progress between the pin and thrum flower, the development of microspores in thrum flower was more slowly than that of the pin flower, but the male gametophytes in thrum flower grew faster. However, mature embryo sac and pollen grains were observed when pin and thrum flower open. According to the reproduction development process of two type flowers, many relatively primitive embryological characteristics, and some relatively evolutionary embryological characteristics, such as orthotropous ovule and 3-cell type pollen grains, coexist in common buckwheat. This study not only accumulated the morphological data of the distylous flower reproductive development in common buckwheat, but also provided embryological evidence for understanding the genetic relationships among the species of Caryophyllales.
