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.

ObjectiveTo comprehensively identify the O-methyltransferase （OMT） genes in Carthamus tinctorius and explore the key OMTs that can catalyze the methylation of flavonoids， providing a basis for understanding the molecular formation mechanism of the structural diversity of flavonoids in C. tinctorius. MethodsThe hidden Markov model was used to systematically identify the type Ⅰ OMTs from the high-quality genome data of C. tinctorius. A suite of bioinformatics tools was employed to systematically analyze the physicochemical properties， gene structure， conserved motifs， chromosomal localization， gene replication events， and collinearity of the identified genes. The target gene was heterologously expressed through the prokaryotic expression system of E. coli， and the protein function was verified by in vitro enzymatic reactions. ResultsA total of 31 type Ⅰ OMTs were identified. CtFOMT1 was successfully cloned and expressed in a soluble form in Escherichia coli. The recombinant protein was purified via Ni²⁺ affinity chromatography to obtain a high-concentration preparation. In vitro enzymatic assays demonstrated that CtFOMT1 utilized S-adenosylmethionine as the methyl donor to catalyze the methylation of the 4′-OH of naringenin， resulting in the production of isosakuranetin. A similar process occurred with the 4′-OH of luteolin， leading to the formation of diosmetin. Subsequent methylation of the 3′-OH group of diosmetin generated 4′-methylchrysoeriol. ConclusionCtFOMT1 can catalyze the methylation of 4′-/3′-OH in the flavonoid skeleton. It is hypothesized that CtFOMT1 may play a role in the biosynthesis of various 4′-/3′-oxymethyl flavonoids in C. tinctorius.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Aim Krüppel-like factor(KLF)2 and 4 are two core transcription factors closely related to vascular homeostasis,with multiple protective effects such as anti-inflammatory,anti-calcification and anti-thrombotic.The aim of this study is to elucidate and validate the vascular homeostasis related gene profile co-regulated by KLF2 and KLF4 in endo-thelial cells.Methods Human umbilical vein endothelial cells(HUVEC)were treated with adenovirus(Ad-KLF2 or Ad-KLF4)and control virus(Ad-NC)for 24 h,RNA was extracted from the cells and analyzed by transcriptomic sequen-cing.The sequencing results of overexpressed KLF2 and KLF4 were superimposed with the sequencing results of reported KLF2/KLF4 double-gene knockout mice.The selected differential expression genes were verified by real-time fluorescence quantitative PCR in HUVEC treated with Ad-KLF2 or Ad-KLF4,and in HUVEC treated with atorvastatin or resveratrol.Results Transcriptomic superposition revealed 256 differential expression genes were up-regulated by KLF2 and KLF4,and KEGG analysis showed that differential expression genes were enriched in hypertrophic cardiomyopa-thy,arrhythmogenic right ventricular cardiomyopathy,dilated cardiomyopathy,ECM-receptor interaction and focal adhesion;there were 145 differential expression genes down-regulated by KLF2 and KLF4,and KEGG analysis showed that differential expression genes were enriched in microRNA of cancer,mineral absorption,glycosaminoglycan biosynthesis-chondroitin sulfate/dermatan sulfate,p53 signaling pathway and biosynthesis of amino acids.Finally,six novel genes regulated by KLF2 and KLF4 were obtained.Conclusion FGFR3,SEMA4B,SEMA6A,PTX3,FABP4 and FABP5 may be novel genes that regulate vascular homeostasis in endothelial cells by the transcription factors KLF2 and KLF4.

Objective To analyze medication patterns and the targets and pathways of core drug combinations in treatment of palpitation.Methods The prescriptions of Li Yaping for treatment of palpitation from March 2023 to March 2024 were collected,and frequency counts of drugs'nature and flavour,channel tropism,and efficacy were performed.Apriori algorithm,association rules,and clustering analysis were carried out using SPSS Modeler 18.0 and SPSS 26.0.The core drugs and disease targets were searched,and gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis were performed on the targets of their therapeutic action for palpitation.Results A total of 220 prescriptions were collected,involving 192 flavors of traditional Chinese medicines,with a cumulative medication frequency of 3978 times,and 18 flavors of high-frequency medicines.The medicines were mainly tonics,sedative,and promoting blood circulation for removing blood stasis.The distribution of medicinal properties were mainly warm,cold and flat.The medicinal flavors were mainly sweet,bitter and pungent,and channel tropism were mostly heart,liver and spleen channel.Association rule analysis showed that Radix Angelicae Sinensis,Radix et Rhizoma Salviae Miltiorrhizae,Radix et Rhizoma Glycyrrhizae,Radix Ophiopogonis,and Radix Astragali were the core drugs.Cluster analysis showed that there was 3 cluster combinations.In the network pharmacology part,there were 181 targets intersected by drug combinations and diseases.KEGG analysis showed that the core drugs for palpitation mainly involved signaling pathways such as phosphoinositide 3-kinase/protein kinase B,hypoxia-inducible factor-1,mitogen-activated protein kinase,interleukin-17,etc.GO analysis obtained 1000 GO pathways,of which 760 were biological processes,93 were cellular components,and 147 were molecular functions.Conclusion In the treatment of palpitation,Li Yaping advocates benefiting qi and promoting yang,removing blood stasis and eliminating turbidity,and tranquilizing the mind,emphasizing the"two hearts in the same adjustment",and treating the heart and liver at the same time,taking into account the spleen and stomach,and the combination of core medicines can intervene in the course of palpitation through multi-components,multi-targets,and multi-pathways,which is of great significance for the treatment of palpitation in the clinical setting.

Objective:To analyze the impact of baseline quantification of hepatitis B core antibody (qHBcAb) on prognosis of patients with hepatitis B virus (HBV) related acute-on-chronic liver failure (HBV-ACLF).Methods:A total of 91 HBV-ACLF patients (HBV-ACLF group), who admitted to Wuxi No.5 People′s Hospital from July 1, 2019 to December 30, 2021, were included in this study. Fifty chronic hepatitis B (CHB) patients (CHB group) and 50 chronic HBV carriers (HBV carrier group) were enrolled as controls. Baseline clinical data such as qHBcAb, blood routine examination biochemical, and coagulation indices, HBsAg, hepatitis B e antigen (HBeAg), HBV DNA levels were recorded and analyzed retrospectively. The HBV-ACLF, HBsAg and HBV-DNA data were converted logarithmically. Patients were followed-up for 90 days. Cox regression was used to analyze the correlation between HBV-ACLF and survival outcome; survival rate was estimated by the Kaplan-Meier method; receiver operating characteristic (ROC) curve was used to evaluate the predictive value of baseline qHBcAb for the prognosis in patients with HBV-ACLF.Results:The baseline qHBcAb level in HBV-ACLF patients was (4.83±0.42) IU/ml, which was significantly higher than that in the CHB group [(4.59±0.54) IU/ml] and chronic HBV carrier group [(3.86±0.74) IU/ml] (all P<0.05). At the end of 90 days follow-up, 46 patients (50.55%) survived, and 45 patients (49.45%) died in the HBV-ACLF group. The baseline qHBcAb level was significantly higher in the survival group [(4.93±0.22) IU/ml] than in the death group [(4.70±0.52) IU/ml, P<0.01]. Significant differences were also found in the alpha fetoprotein, international normalized ratio, prothrombin activity, antithrombin Ⅲ activity, platelet, end-stage liver disease model score and hepatic encephalopathy complication between the two groups ( P<0.05). Cox regression analysis showed that the baseline qHBcAb was an independent risk factor affecting the 90-day survival of HBV-ACLF patients [hazard ratio=0.027,95% confidence interval ( CI) 0.001-0.696, P<0.05]. The area under the ROC curve of baseline qHBcAb level for predicting the 90-day survival outcome of HBV-ACLF patients was 0.639 (95% CI 0.525-0.752, P<0.05), with a cut-off value of 4.89 IU/ml. The cumulative survival rate of patients with baseline qHBcAb≥4.89 IU/ml was higher than that of patients with baseline qHBcAb<4.89 IU/ml ( P<0.05). Conclusions:Higher baseline qHBcAb level is associated with favorable outcome of HBV-ACLF patients and baseline qHBcAb may be used as a new biomarker to predict the clinical outcome of HBV-ACLF patients. HBV-ACLF patients with serum qHBcAb lower than 4.89 IU/ml face increased risk of short-term death.

Endometrial receptivity is key to clinical pregnancy by in vitro fertilization-embryo transfer(IVF-ET)technique.Endometrial thickness(EMT)is a major index for pregnancy monitoring,but the optimal time indicating endometrial receptivity is controversially uncertain.Multiple studies have demonstrated the correlation between EMT and IVF pregnancy outcomes and EMT of a moderate range is essential for good pregnancy outcomes and a thin endometrium produces negative pregnancy outcomes.In this paper,we reviewed the research on the im-pact of EMT on IVF-ET pregnancy outcomes in terms of timing of EMT measurement,clinical pregnancy rate,live birth rate,ectopic pregnancy rate,placenta praevia,and low birth weight,investigating the mechanism of occur-rence and treatment of thin endometrium so as to provide clinical references for improving IVF pregnancy outcomes.

Objective To explore the effects of different endometrial preparation regimens on the pregnancy and obstetrical outcomes of single euploid blastocyst transfer after preimplantation genetic testing for aneuploidies(PGT-A).Methods The clinical data on patients with single euploid blastocyst transfer after PGT-A in our center from September 2015 to July 2021 were analyzed retrospectively.According to the different preparation regimens,the patients were divided into a natural cycle group(n = 80 cycles)and a hormone replacement cycle group(n = 259 cycles).The differences of pregnancy and obstetrical outcomes between the two groups were com-pared.Binary logistic regression was used to explore the influencing factors of pregnancy and obstetrical outcomes after PGT-A.The pregnancy outcomes of different endometrial preparation regimens were further explored by age stratification.Results As compared with that in the natural cycle group,the rate of high-quality blastocyst was significantly higher in the hormone replacement cycle group,but the live birth rate was lower and the abortion rate was higher(P<0.05).There was no statistical difference in the clinical pregnancy rate between the two groups.The incidence of cesarean section and macrosomia was higher in the hormone replacement cycle group than that in the natural cycle group,while the rate of low birth weight was lower,but there were no significant differences(P>0.05).Binary logistic regression showed that female age was an independent influencing factor of abortion.Female age and the days of blastocyst development were independent influencing factors of live birth.However,endometrial prepa-ration regimen was not a factor affecting pregnancy and obstetrical outcomes(P>0.05).The results of further analysis showed that the live birth rate in the natural cycle group was significantly higher than that in the hormone replacement cycle group,while the abortion rate in the natural cycle group was significantly lower than that in the hormone replacement cycle group for female patients aged over 35(P<0.05).Conclusions The endometrial preparation regimens did not affect the pregnancy and obstetrical outcomes of patients receiving single euploid blas-tocyst transfer after PGT-A.However,in the older patients,the natural cycle regimen can obtain a higher live birth rate and a lower abortion rate.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

Objective:To analyze the advantages of the impact of physical activity management under medical supervision on body components and healthy physical fitness.Methods:A total of 106 healthy adults who participated in physical activity management activities in the Health Management Center of Sichuan Academy of Medical Sciences & Sichuan Provincial People′s Hospital from April 1 st 2020 to May 31 th 2021 were enrolled. The subjects were equally divided into a medical supervision group and a self-supervision group with random number table. Both groups performed a 8-week physical activity intervention, followed by the model of “a combination of online home physical activity with offline team exercise, and team exercise interaction with individual physical activity guidance”, while health education was provided and wearable devices were worn to collect exercise data. The medical supervision group completed the set number of exercises under the supervision of the team, with on-site exercise guidance. They were required to participate in weekly one-to-one on-site instruction. The self-management group carried out exercises and participated in weekly one-to-one instruction in accordance according to their own will with online feedback. During the study, 6 cases withdrew, and 52 cases in the supervision group and 48 in the self-management group were obtained. The t and Wilcoxon tests were used to compare the body components and physical fitness of the two groups before and after intervention. Results:The amount of exercise in the supervision group was significantly higher than that in self-management group (1 359 vs 615), and there was no significant differences in exercise intensity (mean heart rate, maximum heart rate and exercise duration) between the two groups (all P>0.05). After the intervention, the body weight, body mass index (BMI), percent body fat, subcutaneous fat area and strength fitness of the supervision group were significantly lower than those before the intervention [(55.36±6.37) vs (56.11±6.33) kg, (21.48±2.85) vs (21.73±2.47) kg/m 2, (27.38±5.34) % vs (28.53±4.99) %, (119.56±48.45) vs (128.70±50.10) cm 2, (24.48±6.37) vs (26.07±5.29) kg], while the cardiorespiratory endurance, flexibility fitness and agility fitness were significantly higher [(33.57±5.06) vs (30.32±4.59) ml·kg -1·min -1, (14.71±7.51) vs (10.54±7.54) cm, (0.44±0.08) vs (0.48±0.05) s] (all P<0.05). After the intervention, the body weight, muscle mass and lean body mass in self-management group were all significantly higher than those before the intervention [(56.83±8.09) vs (56.45±8.22) kg, (38.28±3.19) vs (38.24±5.17) kg; (40.80±4.16) vs (40.32±4.95) kg], and agility fitness was significantly lower [(0.64±0.39) vs (0.49±0.05) s] (all P<0.05). It was also found that improvements regarding the following three indicators were more significant in the supervision group: visceral fat, balance and agility fitness (all P<0.05). Conclusions:Physical activity intervention under medical supervision can significantly improve the body components and physical fitness in healthy adults, as well as exercise compliance and validity.
