Objective: To investigate the impact of RhE antigen-matched transfusion during liver transplantation on early postoperative recovery and complications. Methods: In this retrospective cohort study, ninety-five patients undergoing liver transplantation at Kunming First People's Hospital between January 2022 and July 2025 were enrolled. Patients were divided into two groups: Group 1 (RhE-mismatched transfusion, n=57) and Group 2 (RhE-matched transfusion, n=38). The baseline data, complete blood counts, hepatic and renal function, coagulation parameters, and complication rates between the two groups were compared at postoperative days 1, 3, 5, 7, and 10. Survival analysis was performed using the Kaplan-Meier method. Results: The baseline characteristics were well-balanced and comparable between the two groups (all P>0.05). The early postoperative mortality rate in the mismatched group (31.58%, 18/57) was significantly higher than that in the matched group (10.53%, 4/38) (P=0.017). The incidence of postoperative hepatic encephalopathy was significantly higher in the mismatched group (50.88%, 29/57) than in the matched group (10.53%, 4/38) (P<0.001). The incidence of postoperative haemorrhage in the mismatched group (24.56%, 14/57) was higher than that in the matched group (5.26%, 2/38), with a statistically significant difference (P=0.014). The incidence of perioperative infection in the mismatched group (28.07%, 16/57) was higher than that in the matched group (10.53%, 4/38), with a statistically significant difference (P=0.04). Corresponding odds ratios (OR) and 95% confidence intervals indicated a lower risk of these adverse events in the matched group. On postoperative day 1, the change in activated partial thromboplastin time (-1.6, 20.5) in the mismatched group was greater than in the matched group (-0.2, 5.5). The change in international normalised ratio (-0.56, 1.22) in the mismatched group was greater than in the matched group (-0.18, 0.32), while the change in albumin (-4.0, 4.8) was smaller in the mismatched group than in the matched group (-2.5, 8.8). On postoperative day 5, the change in albumin (-0.41±7.83) in the mismatched group was smaller than in the matched group (2.68±4.53). At postoperative day 7, the change in albumin in the mismatched group (-0.61±7.38) was smaller than that in the matched group (2.51±5.85), while the change in D-dimer in the mismatched group (0.73, 7.4) was greater than that in the matched group (-1.6, 4.3). On postoperative day 10, the mismatched group exhibited significantly higher fibrinogen levels (-1.21, 1.78) than the matched group (-0.49, 0.97), and significantly longer prothrombin times (-11.3, -2.7) than the matched group (-6.2, -0.8) (all P<0.05). The matched group exhibited a mean overall survival (OS) of 32.803 months (95% CI:29.171-36.436 months), significantly exceeding the mismatched group's 28.996 months (95% CI:24.202-33.790 months). The log-rank test yielded statistically significant results (χ =4.307, P=0.038). Conclusion: Implementing RhE blood group-matched transfusion during liver transplantation may help reduce early postoperative mortality and the incidence of major complication rates, promote faster recovery of coagulation and liver function, and thereby improve short-term patient outcomes.

Objective:To evaluate the predictive value of anthropometric indicators in predicting cardiovascular risk in the population with metabolic syndrome(MS).Methods:A cross-sectional study was used to analyze the correlation between anthropometric measures and cardiovascular risk in subjects with MS. Cardiometabolic risk was assessed with cardiometabolic risk index(CMRI). Receiver operating characteristic(ROC) curve analysis was used to assess the predictive power of anthropometric measures for cardiometabolic risk.Results:(1) The anthropometric measures [body mass index(BMI), waist-hip ratio(WHR), waist-to-height ratio(WtHR), body fat percentage(BFP), visceral fat index(VFI), conicity index(CI), a body shape index(ABSI), body roundness index(BRI), abdominal volume index(AVI)] in the MS group were significantly higher than those in the non-MS group( P<0.05). Moreover, there were significant differences in CMRI score and vascular risk between the two groups( P<0.05). (2) Logistic regression analysis showed that the cardiovascular risk was increased with the increases of BMI, VFI, WHR, WtHR, CI, BRI, and AVI after adjusting for confounding factors in the overall population, the non-MS population, and the MS population( P<0.05). (3) In the ROC analysis, the AUC values of BMI, VFI, and AVI were 0.767, 0.734, and 0.770 in the overall population; 0.844, 0.816, and 0.795 in the non-MS population; 0.701, 0.666, and 0.702 in the MS population, respectively. For the overall population and non-MS population, the optimal cut points of BMI to diagnose high cardiovascular risk were 26.04 kg/m 2 and 24.36 kg/m 2; the optimal cut points of VFI were 10.25 and 9.75; the optimal cut points of AVI were 17.3 cm 2 and 15.53 cm 2, respectively. In the MS population, the optimal cut point as a predictor of high cardiovascular risk in young and middle-aged men with MS was 27.63 kg/m 2, and the optimal cut point of AVI in women was 18.08 cm 2. Conclusion:BMI, VFI, and AVI can be used as predictors of cardiovascular risk in the general population. BMI can be used as a predicator of high cardiovascular risk in young and middle-age men with MS. AVI can be used as a predicator of high cardiovascular risk in women with MS.

After statistical analysis, the important items of PBM for liver transplant patients were determined, and a (trial) plan was organized by the Medical Department and training was conducted by Blood Transfusion Department for medical staff training from departments as Anesthesiology, Hepatobiliary and Pancreatology, and ICU; PBM measures for liver transplant patients before, during and after surgery were determined by the Anesthesiology Department, Hepatobiliary and Pancreatic Department, and ICU; PBM was fully implemented in the experimental group with liver transplant patients in our hospital in 2021 as subjects; 30 cases of liver transplantation performed in our hospital in 2020 were selected as the control group, and the general data, preoperative laboratory examination results, and preoperative, intraoperative, and postoperative blood transfusion of the two groups of patients were compared. 【Results】 Compared with the control group, the experimental group did not receive any blood component transfusion before surgery. Intraoperative blood transfusion volume of allogeneic components: red blood cells(U) were 12.75(8.75, 18.63) vs 15.25(8.38, 26.13)(P>0.05), apheresis platelet (treatment volume) was 0(0, 2) vs 1(0, 4.25)(P>0.05), plasma(U) was 2 300(1 550, 3 763) vs 3 650(2 075, 5 400)(P<0.05); cryoprecipitate(U) was 0(0, 10) vs 10(0, 30)(P<0.05); Postoperative blood transfusion volume of allogeneic components were as follows: red blood cells(U) 8.00(3.38, 12.88) vs 11.25(4.75, 19.63)(P>0.05), platelets were not transfused, plasma(U) was 0(0, 0) vs 0(0, 600)(P>0.05), and cryoprecipitates were not transfused. 【Conclusion】 The establishment of PBM model for liver transplant patients and the application of its management measures before, during and after transplantation significantly reduced the intraoperative blood transfusion volume and improved the prognosis of patients after transplantation.

Objective To investigate the clinical significance of fraction exhaled nitric oxide (FeNO) in the diagnosis and monitoring of childhood bronchial asthma (asthma). Methods The FeNO levels of 204 children with acute asthma attack, 148 children with asthma clinical remission, 107 children with cough variant asthma (CVA) and 250 children with pneumonia from March 2016 to March 2017 were retrospectively analyzed and compared. Results The FeNO levels of acute asthma attack, asthma clinical remission, CVA and pneumonia were 18 (10, 37), 16 (10, 38), 18 (9, 31) and 13 (8, 20) nmol/L, and there was statistical difference (P<0.05). The FeNO levels of acute asthma attack, asthma clinical remission and CVA were significantly higher those of pneumonia, and there were statistical differences (P<0.05). There was no statistical difference in the FeNO levels among acute asthma attack, asthma clinical remission and CVA (P>0.05). Conclusions FeNO has clinical significance in the diagnosis of asthma in children, and its clinical significance in monitoring asthma and the prediction of acute attack needs further observations.

There are two kinds ofamelogeningene mutation, including mutation in primer-binding re-gion ofamelogeningene and micro deletion of Y chromosome encompassingamelogeningene, and the latter is more common. The mechanisms of mutation in primer-binding region ofamelogeningene is nu-cleotide point mutation and the mechanism of micro deletion of Y chromosome encompassingamelo-geningene maybe non-allelic homologous recombination or non-homologous end-joining. Among the population worldwide, there is a notably higher frequency ofamelogeningene mutations in Indian popu-lation, Sri Lanka population and Nepalese population which reside within the Indian subcontinent. Thoughamelogeningene mutations have little impact on fertility and phenotype, they might cause incor-rect result in gender identification. Using composite-amplification kit which including autosomal STR lo-cus,amelogeningene locus and multiple Y-STR locus, could avoid wrong gender identification caused byamelogeningene mutation.
