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 evaluate the pregnancy outcomes of assisted reproductive technology （ART） in women with a history of thyroid cancer who retained fertility intentions after completing cancer treatment. MethodsA retrospective analysis was performed on 61 patients with a history of thyroid cancer who underwent in vitro fertilization/intracytoplasmic sperm microinjection and embryo transfer （IVF/ICSI-ET）. These patients were included as the case group. A total of 122 non-cancer patients who received ART during the same period were selected as the control group using 1∶2 matching based on age and oocyte retrieval time. Baseline characteristics， outcomes of the first ART cycle， and cumulative pregnancy outcomes were compared between the two groups. ResultsThere was no significant difference in the basic data， the total amount of gonadotropin （Gn） and the days of use between the case group and the control group （P>0.05）. However， the case group had significantly fewer retrieved oocytes， mature oocytes （MII）， lower fertilization and cleavage rates， and fewer transferable and high-quality embryos， as well as fewer embryos transferred during the first cycle （P < 0.05）. However， there was no significant difference in the rate of first embryo implantation and first clinical pregnancy between the two groups （P>0.05）. In the analysis of cumulative outcomes， the two groups did not show statistically significant differences in the cumulative pregnancy rate， clinical pregnancy rate per transfer cycle， the number of oocyte retrieval cycles required per live birth， the number of embryo transfer cycles required per live birth， and the number of embryos used for each live birth （P>0.05）. However， the cumulative live birth rate was significantly lower in the case group compared to the control group （P=0.005）. ConclusionAfter treatment for thyroid cancer， when ART is used to help pregnant women， the pregnancy outcome is comparable to that of women without tumors. Individualized reproductive management and timely fertility preservation strategies are recommended to optimize reproductive outcomes in this population.

ObjectiveTo investigate the influencing factors and independent risk factors for lower extremity deep vein thrombosis （DVT） in patients with acute necrotizing pancreatitis （ANP）， to analyze the effectiveness of three commonly used risk assessment models for thrombosis （Caprini score， Padua score， and Wells score）， and to provide a reference for clinical identification of high-risk individuals and optimization of prevention and treatment strategies. MethodsA retrospective analysis was performed for the clinical data of 320 patients with ANP who were admitted to Luzhou People’s Hospital and The Affiliated Hospital of Southwest Medical University from April 2013 to April 2024， and according to the presence or absence of DVT during hospitalization， the patients were divided into thrombosis group with 25 patients and control group with 295 patients. After propensity score matching， the two groups were compared in terms of past history and various examination results during hospitalization. The risk factors for lower extremity DVT in ANP patients during hospitalization were analyzed through univariate and multivariate Logistic regression， and a DVT risk prediction model was established based on independent influencing factors. The receiver operating characteristic （ROC） curve was used to assess the performance of models， and the DeLong test was used for comparison of the area under the ROC curve （AUC）， sensitivity， and specificity. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups； the chi-square test was used for comparison of categorical data between groups. ResultsAfter matching， the patients were divided into thrombosis group with 24 patients and control group with 112 patients. The clinical characteristics analysis showed that compared with the control group， the thrombosis group had significantly higher degree of pancreatic necrosis， D-dimer level， Bedside Index for Severity in Acute Pancreatitis （BISAP） score， and proportion of patients undergoing dialysis （all P<0.05）. The multivariable Logistic regression analysis showed that BISAP score， degree of pancreatic necrosis， and D-dimer level were independent risk factors for lower extremity DVT in ANP patients during hospitalization （all P<0.05）. The BISAP-Caprini score model had an AUC of 0.832 （95% confidence interval： 0.722 — 0.942， P<0.001） in predicting the risk of lower extremity DVT， with a Youden index of 1.661， an optimal cut-off value of 0.26， a sensitivity of 75.0%， and a specificity of 91.1%. ConclusionD-dimer， BISAP score， and the degree of pancreatic necrosis are independent risk factors for lower extremity DVT in patients with ANP during hospitalization， and the BISAP-Caprini score model can effectively predict the risk of DVT in ANP patients.

The blood-brain barrier （BBB） is a physical and biochemical barrier that precisely regulates brain homeostasis and plays a central role in controlling the transport of endogenous and exogenous drugs and related metabolites across the blood-brain interface. These functions of the BBB are mediated by its major components， including brain microvascular endothelial cells （BMECs）， tight junction protein complexes， and influx and efflux transporter proteins. One of the pathological features of ischemic stroke （IS） is BBB disruption， which plays an important role in the development of post-stroke brain injury and subsequent neurological dysfunction. Therefore， given the increasing incidence of IS， there is an urgent need to develop new therapeutic strategies to prevent BBB dysfunction and thereby protect injured brain tissue after IS. This study describes the pathological mechanisms by which BMEC injury after IS leads to BBB dysfunction and elucidates the association between BMECs and IS， including the regulation of apoptosis， autophagy， inflammatory responses， oxidative stress， neurotoxic effects， and cerebral edema. In addition， this article summarizes Chinese herbal medicines that may prevent and treat IS by targeting BMECs. These include monomeric compounds and single herbs such as flavonoids， glycosides， phenols， phthalides， terpenoids， and Styrax. Traditional Chinese medicine （TCM） compound formulas and preparations include oral formulations such as Buyang Huanwu decoction， Sailuotong， Naoxintong capsules， Dandeng Tongnao capsules， and Shexiang Tongxin dropping pills， as well as injectable preparations such as Tongluo Jiunao injection， Xingnaojing injection， Danshen polyphenolic acid for injection， Yiqi Fumai injection， and Shuxuetong injection. This study aims to explore the protective effects of TCM against IS through targeted regulation of BMEC function， providing new insights into the mechanisms of IS and endovascular therapeutic strategies.

OBJECTIVE: Based on the PTEN-induced hypothetical kinase 1 (PINK1)/Parkin pathway, the effect of acupuncture pretreatment on the expression of mitochondrial autophagy-related proteins in gastrocnemius muscle tissue of rats with exercise-induced muscle damage (EIMD) was observed, and the underlying mechanism of acupuncture pretreatment for the prevention and treatment of EIMD was explored. METHODS: Of 88 SD male rats, aged 6 weeks, 8 rats were randomly selected as a blank group, and the remaining 80 rats were randomized into a model group and an acupuncture pretreatment group, with 40 rats in each group. Either the model group or the acupuncture pretreatment group was subdivided randomly into 5 subgroups with 8 rats in each one according to the time points of sample collection, 0 h, 12 h, 24 h, 48 h and 72 h after modeling. An intermittent downhill running centrifugal exercise was carried out on an animal experimental treadmill to establish the EIMD model in the model group and the acupuncture pretreatment group. The rats in the acupuncture pretreatment group received acupuncture at "Guanyuan" (CV6) and bilateral "Zusanli" (ST36), once a day for 20 min each time, for 7 consecutive days before EIMD model preparation. Transmission electron microscopy was used to observe the ultrastructure of gastrocnemius muscle tissue in each group. The contents of malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in serum were detected by ELISA. Western blot was used to detect the protein expression of PINK1, Parkin, sequestosome 1 (p62) and microtubule-associated protein light chain 3B (LC3B) in rat gastrocnemius muscle tissue. Real-time PCR was adopted to detect the mRNA expression of PINK1, Parkin, p62 and LC3B in rat gastrocnemius muscle tissue. RESULTS: Compared with the blank group, the mitochondria of gastrocnemius muscles showed obvious swelling in the 0 h, 12 h, 24 h, and 48 h model subgroups , autophagosomes were formed in the 12 h and 24 h model subgroups, and the mitochondrial morphology returned to normal gradually in the 72 h model subgroup. The serum MDA contents of rats in 5 model subgroups increased (P<0.01, P<0.05). The contents of SOD and CAT in the subgroups of 0 h, 12 h, 24 h and 48 h decreased (P<0.05, P<0.01). The protein and mRNA expression levels of PINK1, Parkin and LC3B in gastrocnemius muscle tissue of rats in 0 h, 12 h and 24 h subgroups were elevated (P<0.01); and the protein and mRNA expression levels of p62 in the 0 h, 12 h, 24 h and 48 h subgroups were reduced (P<0.01, P<0.05). Compared with the model subgroup at the same time point, the myofibril damage and the degree of mitochondrial swelling were mild in each acupuncture pretreatment subgroup, and the numbers of autophagosomes were fewer. The contents of MDA in the acupuncture pretreatment subgroups decreased at 0 h, 12 h, 24 h, and 48 h (P<0.05, P<0.01). The contents of SOD and CAT in the 12 h acupuncture pretreatment subgroup increased (P<0.05, P<0.01). The protein and mRNA expression levels of PINK1 and Parkin in the 0 h, 12 h, and 24 h acupuncture pretreatment subgroups decreased (P<0.01, P<0.05). The protein and mRNA expression levels of LC3B in the 12 h acupuncture pretreatment subgroup decreased (P<0.01), and that of p62 in the 0 h and 24 h acupuncture pretreatment subgroups increased (P<0.01, P<0.05). CONCLUSION The intermittent downhill running centrifugal exercise induces the excessive mitochondrial autophagy. Acupuncture pretreatment may attenuate EIMD, and the underlying mechanism is related to the regulation of PINK1/Parkin signaling pathway expression, reducing oxidative stress damage in skeletal muscle cells, and inhibiting mitochondrial autophagy overactivation.

Objective:To investigate the relationship between serum interleukin-33(IL-33),interleukin-1 receptor-associated kinase 4(IRAK4),C-C chemokine receptor 5(CCR5)expression levels and patients with traumatic cerebral hemorrhage(TCH)complicate with acute ischemic stroke(AIS).Methods:162 TCH patients who were admitted to our hospital from March 2022 to January 2024 were selected,the patients were divided into AIS group and non-AIS group according to whether there was AIS in the early postoperative period.Serum IL-33,IRAK4 and CCR5 expression levels in AIS and non-AIS groups were compared,the predictive value of serum IL-33,IRAK4 and CCR5 expression levels in patients with TCH complicate with AIS was analyzed by receiver operating characteristic(ROC)curve,and the influencing factors of patients with TCH complicate with AIS were analyzed by multi-factor Logistic regression model.Results:Serum L-33,IRAK4 and CCR5 expression levels in AIS group were higher than those in non-AIS group(P＜0.05).Patients with TCH complicate with AIS were associated with Glasgow coma scale(GCS)score at admission,cerebral xenon,intraoperative hiatus incision and perioperative hypotension(P＜0.05).Low GCS score at admission,cerebral xenon,intraoperative hiatus incision,perioperative hyhyemia,high IL-33,high IRAK4 and high CCR5 were risk factors for patients with TCH complicate with AIS(P＜0.05).The ROC curve showed that the combination of serum IL-33,IRAK 4 and CCR5 had higher predictive value of patients with TCH complicate with AIS than testing alone(P＜0.05).Conclusion:Low GCS score at admission,cerebral xenon,intraoperative hiatus incision,perioperative hypostasis,high IL-33,high IRAK4 and high CCR5 are risk factors for patients with TCH complicate with AIS,and the predictive value of IL-33,IRAK4 and CCR5 for patients with TCH complicate with AIS is high.

Radiation-induced heart disease(RIHD)is a common and severe complication following radiotherapy for thoracic tumors,significantly impacting patients' long-term prognosis and quality of life.Its pathogenesis is complex,primarily involving oxidative stress,inflammatory responses,endothelial dysfunction,and chronic fibrosis.Currently,there is a lack of effective clini-cal prevention and treatment methods,highlighting the urgent need to develop intervention strategies for RIHD.Tanshinone ⅡA,the main active component of Salvia miltiorrhiza,exhibits mul-tiple pharmacological effects,including antioxidant,anti-inflam-matory,anti-fibrotic,and anti-apoptotic properties.Studies have shown that Tanshinone ⅡA can significantly mitigate radiation-induced myocardial injury and fibrosis,as well as improve cardi-ac function,by scavenging reactive oxygen species,inhibiting in-flammatory pathways,and modulating fibrotic signaling path-ways.This article summarizes the pathogenesis of RIHD and the research progress on Tanshinone ⅡA in the prevention and treat-ment of RIHD,providing new theoretical insights for developing effective cardioprotective strategies.

Objective To analyze the composition and distribution characteristics of death causes among elderly inpa-tients in a municipal hospital based on Diagnosis-Related Groups(DRG).This analysis aims to provide data support for the treat-ment and management of diseases in elderly patients and for the development of related disciplines,ultimately aiming to reduce the mortality rate of elderly patients.Methods A total of 1 811 death cases of elderly inpatients(aged≥60 years)were extrac-ted from the medical record management system and DRG operation analysis system of a prefecture-level tertiary hospital between January 1,2022,and December 31,2024.Information from the inpatient medical records'front page and DRG grouping data were matched.A retrospective analysis was conducted on 1,587 cases with hospitalization durations of 60 days orless included in DRG groups using Excel 2021.Results Elderly inpatients accounted for more than 80% of the total deaths.The deaths were mainly caused by three major categories:respiratory diseases and dysfunctions(35.03%),circulatory system diseases and dys-functions(25.27%),and nervous system diseases and dysfunctions(14.43%).The internal medicine treatment group had the highest number of deaths,followed by the surgical operation group,and then the non-operating room operation group.Among eld-erly deceased patients,83.68% had complications or comorbidities,with 85.47% having severe complications or comorbidities,mainly in patients aged 70 and above.Conclusion Elderly patients are the primary population group at risk of death.Based on the disease characteristics of elderly deceased patients in different age groups,hospitals should focus on strengthening the devel-opment of geriatrics departments,advance disciplinary technologies,and enhance patient satisfaction to provide comprehensive and personalized diagnosis and treatment,thereby supporting healthy aging.

Objective:To explore the relationship between systemic immune-inflammation index(SII),platelet to lymphocyte ratio(PLR)and short-term prognosis in patients with traumatic cerebral hemorrhage.Methods:142 patients with traumatic cerebral hemorrhage who were admitted to our hospital from August 2021 to August 2024 were selected,they were divided into survival group and death group based on their prognosis.General information of patients with traumatic cerebral hemorrhage were collected,the general information,SII,and PLR levels at preoperative and 1 d,3 d postoperative between survival group and death group were compared.Influencing factors were analyzed by COX risk proportional regression model.Predictive value was analyzed by draw receiver operating characteristic(ROC)curves.Results:During 3-month follow up,there were 108 cases survived and 34 cases died,with a mortality rate of 23.94％.There were significant differences between the survival group and the death group in terms of midline shift,Glasgow Coma Scale(GCS)at 3 d postoperative,and National Institutes of Health Stroke Scale(NIHSS)at 3 d postoperative(P＜0.05).The SII and PLR of the death group at 1 d,3 d postoperative were significantly higher than those preoperative,and the SII and PLR of the death group at 1 d,3 d postoperative were significantly higher than those of the survival group(P＜0.05).COX regression analysis results showed that,NIHSS score at 3 d postoperative,SII at 1 d postoperative,SII at 3 d postoperative,PLR at 1 d postoperative,and PLR at 3 d postoperative elevation were independent risk factors for poor short-term prognosis in patients with traumatic cerebral hemorrhage(P＞0.05).ROC curve results showed that,the area under the curve(AUC)for predicting short-term poor prognosis in patients with traumatic cerebral hemorrhage using SII and PLR at 1 d postoperative was 0.743(0.685-0.802)and 0.718(0.650-0.786),respectively.The combined detection of the two predicted the AUC was 0.832(0.783-0.881).The AUC for predicting short-term poor prognosis in patients with traumatic cerebral hemorrhage using SII and PLR at 3 d postoperative was 0.797(0.743-0.851)and 0.755(0.699-0.812),respectively.The AUC for the combined prediction of the two was 0.866(0.825-0.906).The AUC for the combined detection of SII and PLR at 3 d postoperative was greater than that for the combined detection of SII and PLR at 1 d postoperative(P＜0.05).Conclusion:The SII and PLR levels in patients with traumatic cerebral hemorrhage are elevated,and their elevation is a risk factor for short-term poor prognosis in patients with traumatic cerebral hemorrhage.The combined detection of the two has a high predictive power for short-term poor prognosis in patients with traumatic cerebral hemorrhage.
