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.

To thoroughly implement the strategic deployment outlined in the Opinions of the Central Committee of the Communist Party of China and the State Council on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine regarding research on dominant diseases of traditional Chinese medicine and to uphold the development philosophy of equal emphasis on traditional Chinese medicine and western medicine，the China Association of Chinese Medicine has fully played a leading academic role by systematically organizing and conducting a series of academic youth salons on clinical dominant diseases of traditional Chinese medicine. On September 13，2024，the 36^th Youth Salon on Clinical Dominant Diseases was successfully held in Nanjing，focusing on the advantages of traditional Chinese medicine and the integrative traditional Chinese medicine and western medicine in the diagnosis and treatment of erectile dysfunction （ED）. The conference brought together leading experts from traditional Chinese medicine，western medicine，and interdisciplinary fields，facilitating in-depth multidisciplinary discussions that led to key consensus on optimizing traditional Chinese medicine treatment protocols for ED，researching and developing new drugs of traditional Chinese medicine，and advancing interdisciplinary development in traditional Chinese medicine. This salon systematically sorted out the clinical strengths and distinctive features of traditional Chinese medicine in the diagnosis and treatment of ED. Based on current research foundations and clinical needs，it identified key directions for future scientific layout and scientific research tackling： （1） Standardization of syndrome differentiation system of traditional Chinese medicine for ED. （2） Optimization and standardization of intervention methods of integrated traditional Chinese medicine and western medicine. （3） High-quality clinical research guided by evidence-based medicine. （4） In-depth analysis of the pharmacological mechanisms of traditional Chinese medicine in the treatment of ED. （5） Clinical translation and application promotion of new drugs of traditional Chinese medicine. （6） Interdisciplinary integration and innovation in traditional Chinese medicine.

ObjectiveTo analyze the effects of the progestin-primed ovarian stimulation （PPOS） protocol on embryo euploidy rate and clinical pregnancy outcomes in infertile patients. MethodsWomen who underwent Preimplantation genetic testing for aneuploidy （PGT-A） cycles were selected as study participants （a total of 656 cycles and 3 081 blastocysts）. Participants were divided into two age groups （≤35 years and >35 years） and further stratified by ovarian stimulation protocol： the Progestin-Primed Ovarian Stimulation （PPOS） group （n=48 and 60， respectively）， the Luteal Phase Long Protocol （LP） group （n=160 and 57， respectively）， and the Gonadotropin-Releasing Hormone Antagonist Protocol （AP） group （n=220 and 111， respectively）. Baseline characteristics， ovarian stimulation outcomes， and embryo development parameters were compared among the three protocols within each age group. Additionally， clinical pregnancy outcomes of the first frozen embryo transfer （FET） cycle were compared. The primary outcome measure was the embryo euploidy rate. Results① In the ≤35 years age group， baseline follicle-stimulating hormone （bFSH） levels were significantly higher in the PPOS group compared to the LP and AP groups， and the bFSH/bLH ratio was significantly higher in the PPOS group than in the AP group （P < 0.05）. In the >35 years age group， bFSH levels in both the PPOS and AP groups were significantly higher than in the LP group （P < 0.05）.② In the ≤35 years group， there were no significant differences in the rates of metaphase II （MII） oocytes， 2-pronuclei （2 PN） zygotes， cleavage， 2 PN cleavage， blastocyst formation， high-quality embryos， or embryo euploidy between the PPOS group and either the LP or AP groups. However， the PPOS group showed significantly lower values for the following parameters compared to the other two groups： total oocytes retrieved， number of MII oocytes， number of 2 PN zygotes， number of cleaved embryos， number of 2 PN cleaved embryos， number of blastocysts formed， number of high-quality embryos， number of high-grade blastocysts， number of transferable embryos， number of cryopreserved embryos， number of biopsied blastocysts， number of euploid embryos， and the rate of obtaining at least one euploid embryo. In the >35 years group， no significant differences were observed among the PPOS， LP， and AP groups in the rates of MII oocytes， 2 PN cleavage， blastocyst formation， or in the number of euploid embryos， euploidy rate， and the rate of obtaining at least one euploid embryo. However， the PPOS group had significantly lower numbers of total oocytes retrieved， MII oocytes， 2 PN zygotes， cleaved embryos， 2 PN cleaved embryos， blastocysts formed， transferable embryos， and cryopreserved embryos compared to the LP group （P<0.05）. The high-quality embryo rate was significantly lower in the PPOS group than in the AP group （P<0.05）. The numbers of high-quality embryos， high-grade blastocysts， and biopsied blastocysts were significantly lower in the PPOS group than in both the LP and AP groups （P<0.05）. Notably， the 2 PN fertilization rate was significantly higher in the PPOS group than in the AP group， and the cleavage rate was significantly higher in the PPOS group than in both the LP and AP groups （P<0.05）.③ No significant differences were found among the three groups in the biochemical pregnancy rate， clinical pregnancy rate， live birth rate， early miscarriage rate， and late miscarriage rate following the first FET cycle. ConclusionCompared to the other two protocols， the PPOS protocol does not significantly affect embryo euploidy or clinical pregnancy rates. However， in freeze-all cycles with PGT-A， the PPOS protocol does not reduce the rate of chromosomally normal embryos but may decrease the total number of available embryos. It may not be the optimal choice for younger women， but it can be considered as a viable option for women of advanced maternal age.

Purpose: The genomic characteristics of uterine sarcomas have not been fully elucidated. This study aimed to explore the genomic landscape of the uterine sarcomas (USs). Materials and Methods: Comprehensive genomic analysis through RNA-sequencing was conducted. Gene fusion, differentially expressed genes (DEGs), signaling pathway enrichment, immune cell infiltration, and prognosis were analyzed. A deep learning model was constructed to predict the survival of US patients. Results: A total of 71 US samples were examined, including 47 endometrial stromal sarcomas (ESS), 18 uterine leiomyosarcomas (uLMS), three adenosarcomas, two carcinosarcomas, and one uterine tumor resembling an ovarian sex-cord tumor. ESS (including high-grade ESS [HGESS] and low-grade ESS [LGESS]) and uLMS showed distinct gene fusion signatures; a novel gene fusion site, MRPS18A–PDC-AS1 could be a potential diagnostic marker for the pathology differential diagnosis of uLMS and ESS; 797 and 477 uterine sarcoma DEGs (uDEGs) were identified in the ESS vs. uLMS and HGESS vs. LGESS groups, respectively. The uDEGs were enriched in multiple pathways. Fifteen genes including LAMB4 were confirmed with prognostic value in USs; immune infiltration analysis revealed the prognositic value of myeloid dendritic cells, plasmacytoid dendritic cells, natural killer cells, macrophage M1, monocytes and hematopoietic stem cells in USs; the deep learning model named Max-Mean Non-Local multi-instance learning (MMN-MIL) showed satisfactory performance in predicting the survival of US patients, with the area under the receiver operating curve curve reached 0.909 and accuracy achieved 0.804. Conclusion USs harbored distinct gene fusion characteristics and gene expression features between HGESS, LGESS, and uLMS. The MMN-MIL model could effectively predict the survival of US patients.

Objective To propose a decision tree-based optimization algorithm to shorten the time spent and to improve the decision-making efficiency for medical device fault diagnosis.Methods Firstly,a binarized fault state space for medical equipment was constructed;secondly,the binarized fault state space was simplified with logical functions;finally,a greedy algorithm was applied to iterative judgment to build a decision tree for medical device fault diagnosis.The algorithm proposed was compared with the greedy algorithm,Gini coefficient method and random forest algorithm in terms of the result accuracy and time cost and the influences of fault probability distribution and time-consuming differences for the algorithms.A case study on gastric lavage machine fault diagnosis was conducted to demonstrate the algorithm.Results The algorithm proposed behaved better than the greedy algorithm,Gini coefficient method and random forest algorithm in lowered time cost and result accuracy.However,the algorithm showed a decrease in accuracy for the logarithmic distribution of the detection method's time consumption,and it was not sensitive to the changes in the failure rate distribution.The gastric lavage machine case study demonstrated that the algorithm was functionally similar to an experienced engineer.Conclusion The proposed algorithm with overall perspective effectively enhances fault judgment efficiency and facilitates rapid diagnostic decision-making in medical equipment maintenance.[Chinese Medical Equipment Journal,2025,46(5):78-83]
