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.

Liver transplantation provides a life-saving option for patients with end-stage liver disease. Although blood transfusion remains essential in most liver transplan tprocedures, it carries risks of severe complications, including organ failure and mortality. Recent advances have elucidated the complex relationships among transfusion indications, microscopic characteristics of hematology, and adverse reactions. This review synthesizes the latest research progress in blood transfusion in liver transplantation, offering evidence-based strategies for blood transfusion in liver transplantation.

Promoting the international acceptance of clinical studies about traditional Chinese medicine (TCM) interventions is a key strategy for internationalization of TCM. However, the complexities of TCM interventions—in terms of the theories, practice patterns, and components—pose challenges to the design and implementation of clinical studies that are well accepted by the international community. This article summarized the current status of clinical studies about TCM interventions that were published in international journals, explored underlying barriers hindering the international acceptance, and discussed potential strategies for future development.

Objective:To compare the efficacy and prognosis between fluorescent laparoscopic and conventional laparoscopic radical resection of colorectal cancer.Methods:A total of 114 colorectal cancer patients in Bishan District People's Hospital of Chongqing from June 2019 to January 2021 were selected as the research objects, and they were divided into two groups according to the diagnosis and treatment time. Forty-four patients receiving treatment from June 2019 to February 2020 were enrolled as group A, and 70 patients receiving treatment from March 2020 to January 2021 were set as group B. Patients in group A received fluorescent laparoscopic radical resection of colorectal cancer, and patients in group B received conventional laparoscopic radical resection of colorectal cancer. The operation time, intraoperative blood loss, metastatic lymph node clearance rate, clinical efficacy (the overall response rate was calculated as complete remission + partial remission), postoperative complication rate and recurrence rate within 1 year were compared between the two groups.Results:The clearance rate of metastatic lymph nodes was 86.95% (40/46) in group A, which was higher than 72.22% (52/72) in group B, and the difference was statistically significant ( χ2 = 3.55, P = 0.049). There were no statistical differences in operation time and intraoperative blood loss between the two groups (all P > 0.05). The overall response rate was 86.36% (38/44) in group A, which was higher than 74.28% (52/70) in group B, and the difference was statistically significant ( χ2 = 5.03, P = 0.024). The incidence of complications in group A was 9.09% (4/44), which was not significantly different from that in group B (11.42%,8/70) ( χ2 = 0.16, P = 0.692). The recurrence rate within 1 year of group A was 11.36% (5/44), which was lower than that of group B (24.42%, 15/70), but the difference was not statistically significant ( χ2 = 1.89, P = 0.169). Conclusions:Compared with conventional laparoscopy, fluorescent laparoscopic radical resection of colorectal cancer has better clinical efficacy, higher clearance rate of metastatic lymph nodes, and does not increase the incidence of postoperative metastasis and complications.

Objective:To compare the early and mid-term results of hybrid coronary revascularization (HCR) and minimally invasive multivessel coronary artery bypass grafting (MICS-CABG) in coronary artery disease patients with low left ventricular ejection fraction and non diabetes mellitus, and to explore the indication of HCR and MICS-CABG.Methods:A retrospective cohort analysis of HCR and MICS-CABG cases with preoperative left ventricular ejection fraction less than 0.40, and without diabetes mellitus were conducted in Xijing Hospital from January 2015 to December 2019. 36 cases in HCR group and 17 cases in MICS group were included in this study. For HCR procedure, minimally invasive left internal mammary artery(LIMA) to the left anterior descending artery (LAD) bypass surgery were performed, and followed by percutaneous coronary intervention (PCI) to treat non LAD lesion 1 to 4 weeks later. MICS-CABG procedure was performed through left anterior small thoracotomy minimally invasive direct coronary artery bypass grafting for multiple diseased vessels.Results:The preoperative SYNTAX score in MICS group was significantly higher than that in HCR group ( P<0.05). There was no perioperative death in both groups. Troponin I, postoperative drainage volume, blood transfusion volume and ventilator ventilation time in MICS group were significantly higher than those in HCR group ( P<0.05). After 12 months follow-up, no patient died in both groups. Furthermore, all LIMA grafts were patency. The stenosis rate of drug-eluting stents in HCR group was similar to that of great saphenous vein grafts in MICS group. LVEF and left ventricular end diastolic diameter of both groups were significantly improved 12 months after operation ( P<0.05). Conclusion:HCR and MICS-CABG are minimally invasive and safe treatment for multivessel coronary artery disease patients with low ejection fraction and non diabetese mellitus. The early and mid-term therapeutic effects are satisfactory. If coronary artery lesions other than LAD are suitable for PCI, HCR should be the preferred treatment.

One of the distinct characters of Latrodectus tredecimguttatus is that its toxic components exist not only in the venomous glands, but also in the tissues outside the venomous glands and even in the eggs. Investigation on the toxins outside the venomous glands can deepen our understanding of spider toxins and discover new lead molecules with important application prospects. In order to explore the low-abundance proteinaceous toxins in the L. tredecimguttatus eggs, we used bioinformatic strategies to mine a gene sequence encoding a peptide toxin from the transcriptome of L. tredecimguttatus eggs, and then heterologously expressed the gene successfully with a 3'-RACE combined with nest PCR strategy. Biological activity analyses indicated that the expressed peptide toxin, named latroeggtoxin-Ⅵ (LETX-Ⅵ), could inhibit Na⁺ channel currents in ND7/23 cells and promote dopamine release from PC12 cells, without obvious toxicity against Periplaneta americana and bacteria as well as fungi including Staphylococcus aureus and Candida albicans, demonstrating that LETX-Ⅵ is a mammal-specific neurotoxin with a potential application prospect in development of the tool reagents for neurobiological study and the drugs for treating related diseases.

Objective:To study on the association between vasoactive-inotropic score(VIS) and mortality of total arch replacement in Stanford type A aortic dissection(TAAD) patients.Methods:Data of TAAD patients admitted from January 2018 to November 2018 were analyzed retrospectively. According to the inclusion and exclusion criteria, 187 patients were finally included in the analysis. 30-day mortality was calculated and the patients were divided into death group(18 cases) and non-death group(169 cases). The VIS at each time point and perioperative indexes of the two groups were compared. The value of VIS in predicting mortality was analyzed.Results:The 30-day mortality was 9.63%(18/187). The operation time, cardiopulmonary bypass time, ventilator assistance time, the incidence of tracheotomy and major postoperative complications in the death group were significantly higher than those in the non-death group( P<0.05). VIS of death group was significantly higher than that of non-death group( P<0.05). At each time point, the area under ROC curve(AUC) of VIS was greater than 0.500( P<0.05), among which AUC of ICU 48 h VIS was the largest(0.817), and the best cut-off point of ICU 48 h VIS was determined to be 9, sensitivity 61.1%, specificity 92.3%. Logistic regression analysis showed that ICU 48 h VIS was an independent risk factor for predicting the death of total arch replacement in TAAD patients( OR=1.465, 95% CI: 1.194-1.796, P<0.001). Conclusion:When ICU 48 h VIS≥9, the risk of death was increased in patients with total arch replacement of TAAD. VIS may be a useful reference index for predicting the mortality of total arch replacement in TAAD patients in the early postoperative period.

Objective    To discuss the diagnosis and treatment of culture-negative aortic infective endocarditis. Methods    The clinical data of 73 patients with infective endocarditis of the aortic valve whose results of bacteria culture were negative from January 2013 to January 2018 were retrospectively analyzed, including 59 males and 14 females aged 14-71 (39.2±14.8) years. Results    Sixty seven (91.8%) patients received aortic valve replacement, 2 (2.7%) patients received the second operation in hospital, and 12 (16.4%) patients had concomitant mitral valvuloplasty. In-hospital death occurred in 8 (11.0%) patients. Postoperatively, 11 (20.7%) patients had a low cardiac output and 4 (11.0%) patients had heart block, and 1 patient required implantation of a permanent pacemaker. The 1- and 5- year survival rates were 92.3%±2.3% and 84.5%±4.5%, respectively. Conclusion    There are difficulties in the diagnosis and treatment of culture-negative infective endocarditis. Most of the affected patients are in a healed status, which could be a cause of negative culture results. In-hospital mortality in the patients is associated with a history of previous cardiac surgery, whereas the long-term survival rate is good for the patients after surgery.
