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.

Objective:To identify the relevant factors for the first-course remission of acute myeloid leukemia (AML) and to develop a predictive model as well as assess its predictive capability.Methods:Clinical data of 749 patients newly diagnosed with AML admitted to the Department of Hematology, the First Affiliated Hospital, Zhejiang University, School of Medicine from January 1, 2019, to April 30, 2023, were collected and randomly divided into training and validation sets. Multivariate logistic regression analysis was conducted to determine variables associated with complete remission in the first course of induction therapy, and a predictive model was established based on these variables. The receiver operating characteristic (ROC) curve of the predictive model was plotted, and the area under the curve (AUC) was calculated.Results:The indicators predicting the first remission course included peripheral blood white blood cell count during onset, CBF::MYH11 fusion gene, CEBPA bZIP region mutation, myelodysplastic syndrome-related gene mutation, and induction chemotherapy regimen selection as independent factors for the first remission course. The model’s area under the training and validation curves was 0.738 (95% CI: 0.696-0.780) and 0.726 (95% CI: 0.650-0.801), respectively. The Hosmer-Lemeshow test results yielded P-values of 0.993 and 0.335, respectively. Conclusion:In this study, the developed model demonstrates a strong predictive capability for the efficacy of the first course of patients with AML, providing valuable guidance to clinicians in assessing patient prognosis and selecting appropriate treatment strategies.

Objective To elucidate the expression characteristics of the NUAK family SNF1-like kinase 2(NUAK2)in ovarian serous carcinoma and determine its regulatory roles in cell proliferation and apoptosis.Methods Fifty-seven patients with ovarian serous car-cinoma(observation group)and 57 patients with ovarian serous cystadenoma(control group)were selected from June 2019 to December 2022.The GEPIA database was used to assess the expression patterns of NUAK2 in ovarian serous carcinoma.Immunohistochemistry was used to detect the expression of NUAK2,proliferating cell nuclear antigen(PCNA),and B-cell lymphoma-associated X antigen(BAX).Western blotting was performed to evaluate the expression of NUAK2 in the human ovarian serous carcinoma cell lines(SKOV3)and the human ovarian surface epithelial cell lines(HOSEpiC).SKOV3 cells were transfected with the siRNA-NUAK2 plasmid to establish the si-NUAK2 group,or with the empty transfection vector(EV)or a blank solution(NC)to establish control groups.Western blotting was sub-sequently used to detect the expression of NUAK2,PCNA,and BAX.The CCK-8 method was used to assess cell proliferation activity,and flow cytometry was used to quantify apoptosis.Results The GEPIA database analysis showed a significant increasing trend in the expres-sion of NUAK2 in ovarian cancer(P<0.05).Immunohistochemical analysis revealed a significantly higher NUAK2 positive rate in ovarian serous carcinoma tissue than that in the control group.Moreover,significant differences in the expression of NUAK2 were observed across different lesion grades and maximum tumor diameters(P<0.05).A significant positive correlation was found between NUAK2 and PCNA(P<0.05),whereas a significant negative correlation was observed between NUAK2 and BAX(P<0.05)in ovarian serous carcinoma.In vitro cell culture experiments showed that the expression level of NUAK2 was significantly higher in SKOV3 cells than that in HOSEpiC cells(P<0.05).The si-NUAK2 group exhibited significantly lower cell proliferation activity and PCNA expression and significantly higher apoptosis rate and BAX expression than those in the EV and NC groups(P<0.05).Conclusion NUAK2 is overexpressed in ovarian serous carcinoma and promotes tumor progression by enhancing cell proliferation and suppressing apoptosis.

Objective: To investigate the aberrant alterations of microRNAs ( miRNAs) in exosomes derived from bone marrow stromal cells ( BMSCs) in the bone marrow supernatants of patients with acute myeloid leukemia (AML) and their impact on the prognosis of AML patients . Methods: Bone marrow supernatant samples were col- lected from three AML patients and three healthy donors . Exosomes were isolated using a commercial kit , identif- ying the morphology and marker expression , and subjected to miRNA sequencing to determine differentially ex- pressed miRNAs (DE-miRNAs) . The DE-miRNAs were then intersected with the exosomal miRNA expression pro- files of primary AML cells (GSE64029) to exclude AML cell - derived signals and to identify BMSC-derived DE - miRNAs . Subsequently , candidate miRNAs were identified through Cox regression and Lasso regression analyses based on data from The Cancer Genome Atlas (TCGA) . A prognostic risk model for AML was constructed , and pa- tients were stratified into high-risk and low-risk groups according to the median risk score . The prognostic value and clinical relevance of the model were further validated . Finally , the target genes of the candidate miRNAs were pre- dicted , followed by pathway enrichment analysis , construction of key regulatory networks , and correlation analysis between the expression levels of key miRNAs and their corresponding target genes . Results: Isolated exosomes ex- hibited a typical cup-shaped morphology with intact structures with particle size of 30 - 150 nm , and expressed exo- somal markers CD63 , ALIX , and TSG101 . miRNA sequencing identified 103 DE-miRNAs in AML patients com- pared with healthy donors; after intersection with the GSE64029 dataset , 83 BMSC-derived DE-miRNAs were re- tained . Among these , five candidate miRNAs ( miR-25-3p , miR-532-5p , miR-194-5p , miR-10a-5p , and miR- 20a-5p) were used to construct the prognostic model . Kaplan-Meier survival analysis demonstrated significantly lon- ger overall survival in the low-risk group compared with the high-risk group (P < 0. 05) . The areas under the ROC curve for the training/validation cohorts were 0. 80/0. 74 , 0. 80/0. 78 , and 0. 79/0. 64 at 1 , 2 , and 3 years , re- spectively . The prognostic model was significantly associated with risk stratification , patient age , and FAB classifi- cation (P < 0. 05) . KEGG pathway enrichment revealed that target genes of the candidate miRNAs were closely linked to cancer-related signaling pathways , including hepatocellular carcinoma , breast cancer , and non-small cell lung cancer. Correlation analysis indicated that the candidate miRNAs were significantly associated with key genes such as HIF1A , CREB1 , PIK3CA , IGF1R , PIK3R1 , TIAM1 , CRK , and PTEN (P < 0. 05) . Conclusion AML patients exhibit distinct miRNA expression profiles in BMSC-derived exosomes . A five-miRNA signature ( miR-25 - 3p , miR-532-5p , miR-194-5p , miR-10a-5p , and miR-20a-5p) demonstrates robust prognostic performance , sup- porting its potential clinical utility in risk stratification and outcome prediction for AML.

Objective:To evaluate the efficacy of Tongdu Tiaoshen acupuncture combined with low-frequency electrical pulse in the treatment of neurogenic bladder (NB) caused by spinal cord injury (SCI); To explore its effects on urodynamics.Methods:A randomized controlled trial study was conducted. A total of 116 patients with NB caused by SCI in the First Affiliated Hospital of Hunan University of Chinese Medicine from January 2022 to June 2024 were selected as the observation objects and divided into 2 groups with random number table method, with 58 cases in each group. On the basis of conventional bladder function training, the control group was given low-frequency electronic pulse therapy, while the observation group was treated with the Tongdu Tiaoshen method on the basis of the control group. Both groups were treated continuously for 3 months. The urination conditions of the patients were observed before and after the treatment respectively, and the residual urine volume, single urine volume within 24 hours, the number of urine leaks within 24 hours, and the number of urinations within 24 hours were recorded; urodynamic parameters such as bladder volume, urine flow rate, detrusor pressure, bladder compliance, and detrusor contractility were measured using a urodynamic analyzer; the severity of NB symptoms was evaluated using the Chinese version of the Neurogenic Bladder Symptom Scale (NBSS), and the quality of life was evaluated using the Chinese version of the Short Form Health Assessment Scale (SF-Qualiveen). The levels of IL-1β, IL-6 and TNF-α were detected by ELISA. Adverse reactions were recorded during the treatment period and the clinical efficacy was evaluated.Results:The total effective rate was 91.38% (53/58) in the observation group and 75.86% (44/58) in the control group. There was a statistically significant difference between the two groups ( χ2=5.10, P=0.024). After treatment, the residual urine volume, single urine volume within 24 hours, frequency of urine leakage within 24 hours, and frequency of urination within 24 hours in the observation group were lower than those in the control group ( t values were -15.68, 3.75, -3.81, and -7.54 respectively, P<0.01). The bladder capacity, urine flow rate, detrusor pressure, bladder compliance and detrusor contractility were higher than those of the control group ( t values were 11.04, 7.49, 9.76, 5.65 and 4.36 respectively, P<0.01), while the NBSS score and SF-Qualiveen score were lower than those of the control group ( t values were -10.82 and -9.83 respectively, P<0.01). No obvious adverse reactions occurred in either group during the treatment period. Conclusion:Tongdu Tiaoshen acupuncture combined with low-frequency electrical pulses can improve the bladder function of NB caused by SCI, restore urodynamics, and improve the quality of life. Its mechanism may be related to the inhibition of inflammatory responses.

The theory of five spirits(mind,eternal soul,corporeal soul,consciousness and will)is an important part of traditional Chinese medicine(TCM)theory,which reveals the human mental and psychological activities.Five-spirit theory takes the shape of modern cognitive psychology.Language is an important part of cognitive activities.Under the guidance of the five-spirit theory of TCM,and by combining the research results of modern cognitive psychology,this paper initially constructs a language processing model,and proposes that heart-mind,spleen-consciousness,kidney-will,and liver-soul are all involved in the formation of language.Moreover,the pathogenesis of post-stroke aphasia(PSA)is explored from the perspective of the five spirits.It is proposed that PSA refers to the comorbidity of body and spirit,and its pathogenesis is related to the disorders of the five spirits.After analyzing the clinical manifestations of PSA,it is suggested that malnutrition of heart-mind and insufficient kidney-will contribute to the pathogenesis of auditory comprehension and reading obstacles in patients with PSA,and the deactivation of liver-soul is closely related to spontaneous speech and naming obstacles.The treatment of PSA should be focused on nourishing blood and tranquilizing mind,enhancing consciousness and strengthening will,and suppressing liver to tranquilize soul.And the prescriptions of Pingbu Zhenxin Pills,Zhiyi Decoction plus Dingzhi Pills,and Dinghun Decoction can be chosen for modified use.The acupuncture and moxibustion can also be used for PSA,by performance mainly on the acupoints of heart meridians,pericardial meridians,spleen meridians,kidney meridians and liver meridians.The syndrome differentiation and treatment system for PSA with the combination of Chinese medicine and acupuncture based on the five-spirit theory makes up for the shortcomings of stress on the physique while ignorance of the spirit in the conventional zang-fu organ syndrome differentiation,and expands the methods for early intervention of PSA with TCM and approaches to improve the prognosis of rehabilitation.
