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.

Insufficient future liver remnant volume remains a critical limitation for single-stage resection in patients with hepatic malignancies. The techniques for promoting future liver remnant hypertrophy to realize two-stage hepatectomy include portal vein embolization， associating liver partition and portal vein ligation for staged hepatectomy， and portal vein ligation. In recent years， the application of auxiliary liver transplantation has further facilitated two-stage total hepatectomy. This article systematically reviews the clinical applications of these techniques and analyzes their advantages and limitations， so as to provide a reference for optimizing clinical decision-making.

Objective To evaluate answers to typical clinical questions related to neuro-ophthalmology generated by Artificial Intelligence(AI)Large Language Models(LLM)and to explore the performance of neuro-ophthalmology-related questions on LLM in a multidimensional manner using objective and expert assessment.Methods Multicenter,random-ized,cross-sectional pilot study.Thirty typical questions related to neuro-ophthalmology were selected based on four per-spectives:definition,etiology,clinical manifestations and signs,and treatment and prognosis,and were analyzed quantita-tively using Deepseek,Wenxin Yiyin 4.0,Doubao,and Kimi 1.5,which are four open-source LLMs in China,and quantita-tively analyzed with objective assessment;and quantitatively rated by three ophthalmologists using expert assessment for 120 answer texts.Three ophthalmology experts quantitatively scored the 120 answer texts.Three ophthalmologists quantita-tively scored the 120 answer texts.Level 3,5,and 4 Likert scales were developed according to the completeness,accura-cy,professionalism,relevance,and criticality of the question texts,respectively.The best-performing LLM was selected,and its performance was observed across the four types of questions.Additionally,three other experts assessed whether the best-performing one could be evaluated as a substitute for real-world doctor-patient communication.Results In the objective Chinese text reading difficulty analysis,the differences in total word count among the four LLMs were statistically significant(all P＜0.001).Of the four LLMs,Kimi 1.5 performed the best,with frequencies of 61％,29％,and 41％for the highest scores in completeness(3),accuracy and professionalism(5),and relevance and usefulness(4),respective-ly.Kimi 1.5 performed more consistently on the questions on the four areas of neuro-ophthalmologic disorders:definition,etiology,clinical manifestations and signs,treatment,and prognosis,with no between-group differences(P＞0.05).Con-clusion Chinese language LLMs have great potential in the clinical application of neuro-ophthalmology.Kimi 1.5 outper-forms other LLMs in terms of completeness,accuracy,professionalism,relevance,and usefulness,but it still cannot re-place real-world doctor-patient communication.There is a need to explore new diagnostic and therapeutic model of AI+physician in the future.

Purpose: The prevalence of psychological distress is frequently observed among old adults with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, current researches are insufficient to clarify the correlation among these relevant factors. This study examined the effects of symptom burden, psychological resilience, coping styles, and social support on psychological distress. Methods: Two hundred fifty five elderly patients with AECOPD were conveniently selected in Taian, Shandong Province. The General Information Questionnaire, Distress Thermometer, The Revised Memorial Symptom Assessment Scale, Connor-Davidson Resilience Scale, Simplified Coping Style Questionnaire, Perceived Social Support Scale were used to investigate. The relationship among factors was estimated by using a structural equation model. Results: Psychological distress score of elderly patients with AECOPD was (5.25 ± 1.01); coping styles, psychological resilience, symptom burden, and social support directly affected psychological distress (thedirect effects were À.93, .17, .17, and À.09); coping styles had the largest total effect on psychological distress (the total effect was À.93); psychological resilience indirectly affected psychological distress through coping styles (the indirect effect was À.74); symptom burden indirectly affected psychologicaldistress through psychological resilience (the indirect effect was .25); social support indirectly affected psychological distress through symptom burden, psychological resilience, and coping styles (the indirecteffect was À.80). Conclusion The psychological distress of elderly patients with AECOPD is at a moderate level; coping styles, psychological resilience, and social support have positive effects on alleviating the psychological distress of elderly patients with AECOPD; symptom burden is negatively correlated with psychological distress.Healthcare professionals should pay more attention to elderly patients with AECOPD who are particularly prone to experience higher levels of psychological distress, especially in the presence of low coping style, limited psychological resilience, inadequate levels of social support, and high symptom burden.

Background The incidence of mental disorders is steadily increasing.However,antipsychotic medications,commonly used in treatment,can lead to drug-induced amenorrhea in female patients.This side effect significantly reduces medication adherence and increases the risk of disease recurrence.Therefore,addressing drug-induced amenorrhea in female patients has become an urgent problem requiring effective solutions.Objective To explore the efficacy and safety of traditional Chinese medicine compound in treating antipsychotic-induced amenorrhea,so as to provide guidance for the treatment of this condition using traditional Chinese medicine compound.Methods On September 4,2022,a computerized search was conducted on across multiple databases,including China National Knowledge Infrastructure,VIP Database,Wanfang Database,China Biomedical Literature Database,PubMed,Cochrane Library and Embase,and randomized controlled trials(RCT)of traditional Chinese medicine compound in treating antipsychotic-induced amenorrhea were collected.The quality of the included literature was assessed using Cochrane 5.3 bias risk assessment tool.Meta-analysis was performed to assess the total effective rate,cure rate,incidence of adverse reactions and recurrence rate using RevMan 5.3.Results Ultimately,22 RCT involving 1879 patients were included.Meta-analysis results showed that the total effective rate(RR=1.29,95%CI:1.16～1.44)and cure rate(RR=1.62,95%CI:1.45～1.80)of traditional Chinese medicine compound or its combination with western medicine in treating antipsychotic-induced amenorrhea were significantly higher compared to western medicine alone.Moreover,the incidence of adverse reactions(RR=0.56,95%CI:0.41～0.76)and recurrence rate(RR=0.16,95%CI:0.06～0.42)were significantly lower than those of western medicine alone.Conclusion Traditional Chinese medicine compound may offer benefits in ameliorating antipsychotic-induced amenorrhea and its safety is better than simple western medicine treatment.

Objective To analyze three-dimensional imaging characteristics and advantages for severe portal vein stenosis after liver transplantation, and to evaluate clinical efficacy of portal vein stent implantation. Methods Clinical data of 10 patients who received portal vein stent implantation for severe portal vein stenosis after liver transplantation were retrospectively analyzed. Imaging characteristics of severe portal vein stenosis, and advantages of three-dimensional reconstruction imaging and interventional treatment efficacy for severe portal vein stenosis were analyzed. Results Among 10 patients, 3 cases were diagnosed with centripetal stenosis, tortuosity angulation-induced stenosis in 2 cases, compression-induced stenosis in 2 cases, long-segment stenosis and/or vascular occlusion in 3 cases. Three-dimensional reconstruction images possessed advantages in accurate identification of stenosis, identification of stenosis types and measurement of stenosis length. All patients were successfully implanted with portal vein stents. After stent implantation, the diameter of the minimum diameter of portal vein was increased [(6.2±0.9) mm vs. (2.6±1.7) mm, P<0.05], the flow velocity at anastomotic site was decreased [(57±19) cm/s vs. (128±27) cm/s, P<0.05], and the flow velocity at the portal vein adjacent to the liver was increased [(41±6) cm/s vs. (18±6) cm/s, P<0.05]. One patient suffered from intrahepatic hematoma caused by interventional puncture, which was mitigated after conservative observation and treatment. The remaining patients did not experience relevant complications. Conclusions Three-dimensional visualization technique may visually display the location, characteristics and severity of stenosis, which is beneficial for clinicians to make treatment decisions and assist interventional procedures. Timely implantation of portal vein stent may effectively reverse pathological process and improve portal vein blood flow.

Background and purpose:Limbs soft tissue sarcoma(STS)is a common malignant tumor,and surgical resection is the main treatment method for it.The concept of barrier made us realize the blocking effect of natural barrier on STS,and we aimed to search for tissues that can act as barrier,and to perform complete resection of surgical margins around the tissue barrier.This study aimed to investigate the feasibility,safety and prognosis of barrier resection in the treatment of limbs STS.Methods:From December 2013 to September 2016,data of 72 patients who underwent barrier resection of STS of extremities in department of oncosurgery,Minhang Branch,Fudan University Shanghai Cancer Center were retrospectively analyzed,and the resection margin was sampled.All 72 patients underwent preoperative magnetic resonance imaging(MRI)or computed tomography(CT)design,and the physiological barrier or at least 3 cm distance was found outward from the anatomical location of the tumor.And en bloc excision was performed outside this barrier or at a distance of 3 cm.The influence of postoperative pathological margin,musculoskeletal tumor society(MSTS)score and postoperative complications on the patients were analyzed.The 1-and 3-year locoregional recurrence-free survival(LRFS)rates and sarcoma-specific survival(SSS)rates were evaluated,and the influencing factors were analyzed.This study was approved by the Ethics Committee of Fudan University Shanghai Cancer Center(number:1212117-12&1212117-12-1301).Results:All patients had negative margins.The 1-and 3-year LRFS rates were 98.2%and 93.3%,respectively.The 1-and 3-year SSS rates were 98.4%and 94.2%,respectively.The mean MSTS scores were 28.3 preoperatively and 25.5 postoperatively.Surgical complications were grade 1 to 2 in 20 cases and grade 3 in 1 case,and there were no grade 4 to 5 complications.Conclusion:Based on the combination of clinical,imaging and pathology data,barrier resection,including tumor resection and functional reconstruction,can be applied to the surgical treatment of STS,with good feasibility and safety,reliable margin and satisfactory local control.

Objective To analyze the clinical characteristics of C-TI-RADS 3 thyroid nodules with a diameter greater than 2 cm and explore their correlation with gender,nodule ingredient,contralateral cancer presence,diffuse echo changes,TPOAB and TGAB.Methods A retrospective analysis was made on the clinical and pathological information of 94 patients with thyroid nodules who were admitted to our department from September 2022 to March 2023.All the patients underwent cytological and/or histopathological examinations.The proportions of TBS I category,benign tumors,low-risk tumors,and malignant tumors were calculated.The proportion of TBS type Ⅰ,benign tumors,low-risk tumors,and malignant tumors was quantified.Subsequently,a comparative analysis was conducted among the benign,low-risk,and malignant groups in terms of clinical characteristics including gender distribution,nodule composition,contralateral cancer occurrence,diffuse echo changes presence,as well as TPOAB and TGAB levels.Results Seven cases in TBS I category were excluded.Among the remaining 87 cases with confirmed pathology results for nodules,there were 72 benign cases(38 cytology cases and 34 histology cases),5 low-risk thyroid tumors(2 cytology cases and 3 histology cases),10 malignant cases(8 PTC cases,1 FTC case,and 1 MTC case).There was a significant difference in nodule ingredient(cystic/solid)between different pathological types(x2=10.369,P=0.006).However,no statistical significance was found in terms of gender,diffuse echo changes,contralateral cancer presence,TPOAB or TGAB(P＞0.05).Further analysis showed that the proportion of solid component was higher in low-risk tumors than in benign nodules(x2=9.571,P=0.002).No statistical significance was found between malignant nodules and low-risk nodules(x2=2.143,P=0.143),or between malignant nodules and benign nodules(x2=2.165,P=0.141).Conclusion Although TI-RADS 3 nodules are generally considered as potentially benign according to various versions of thyroid imaging reporting and data system,malignant nodules still account for a certain proportion.Attention should be paid to thyroid nodules with a typical ultrasonic signs,such as cystic nodules,thyroid follicular tumors and medullary thyroid carcinoma.Ultrasound guided fine needle aspiration cytopathology is necessary for evaluating benign and malignant nodules.It is necessary to pay attention to unsatisfactory or undiagnosable specimens to improve the accuracy of diagnosis.
