Objective To investigate the therapeutic efficacy of granulocyte colony-stimulating factor in combination with tadalafil in patients with thin endometrium undergoing artificial cycle frozen-thawed embryo transfer(FET).Methods A prospective randomized clinical trial was conducted involving sixty patients with thin endo-metrium who underwent artificial cycle FET at the Reproductive Center of Qinhuangdao First Hospital between January 2021 and October 2023.The patients were randomly assigned to two groups:the control group(n=30)received tadalafil,while the study group(n=30)received granulocyte colony-stimulating factor in addition to tadalafil.Endometrial ultrasound characteristics,uterine artery blood flow parameters,and pregnancy outcomes were compared between the two groups before and after treatment.Results Before treatment,no significant differ-ences were observed between the research group and the control group in terms of endometrial thickness or endome-trial volume(P>0.05).Ultrasound assessments were repeated after 8 and 14 days of treatment.Compared with baseline measurements,both endometrial thickness and volume exhibited significant increases in both groups(all P<0.05).By day 14 post-treatment,the research group demonstrated significantly greater endometrial thickness and volume compared to the control group(P<0.05).With regard to endometrial patterns,no significant differences were noted between the two groups prior to treatment(P>0.05).After 14 days of treatment,the proportion of patients exhibiting a Type A endometrial pattern in the research group was significantly higher than that in the control group(P<0.05).Prior to treatment,no statistically significant differences were observed between the two groups in terms of pulsatility index(PI),resistance index(RI),systolic/diastolic ratio(S/D),vascularization index(VI),flow index(FI),or Vascularization Flow Index(VFI)(all P>0.05).Following 14 days of treatment,both groups showed significant increases in VI,FI,and VFI compared to baseline values(all P<0.05),along with significant reductions in PI,RI,and S/D(all P<0.05).At 14 days post-treatment,the S/D ratio in the research group was significantly lower compared to the control group,while the VFI was significantly higher(P<0.05).However,statistical analysis showed no significant differences between the two groups in terms of embryo implanta-tion rate,clinical pregnancy rate,early miscarriage rate,and live birth rate(P>0.05).Conclusion For patients with thin endometrium undergoing FET,the combination of granulocyte colony-stimulating factor and tadalafil is more effective than tadalafil alone in improving endometrial receptivity and uterine blood perfusion.

Poliovirus receptor(PVR)family includes several immune checkpoint receptors such as T cell immunoglobulin and immunoreceptor tyrosine-based inhibition motif structural domains(TIGIT),CD96 and CD226,and their ligands CD155 and CD112,etc.PVR family members have sequence homology and highly interact with each other for synergistic stimulatory or inhibitory effects,forming a complex immunomodulatory network together.The co-signaling network formed by PVR family members is of great significance and has become a major hot spot in hematologic tumor immunotherapy in recent years.This review describes the structure of PVR family members,their mechanism of action,research progress in hematological tumors,and their prospects for application in the immunotherapy of hematologic tumors.

Objective:To explore the impact of "basic nursing" course with signature pedagogy on undergraduate nursing students' critical thinking, professional identity, and professionalism.Methods:A signature pedagogy method for the "basic nursing" course was established using narrative as a theoretical lesson and scenario-simulation as a laboratory lesson. Ninety sophomore nursing students in the 2020 undergraduate nursing program were selected as the participants of a controlled pre-post study. The students were evaluated using the Critical Thinking Inventory, the Professional Identity Questionnaire, and the Professionalism Inventory before and after the course. Semi-structured interviews were conducted at the end of the course to gain an in-depth understanding of their learning experience. Data analysis was conducted using SPSS 26.0 and Nvivo 11.0 Colaizzi's seven-step method was used for analysis of qualitative research.Results:A total of 87 nursing students participated in the course and 83 were included in the quantitative analysis. The total scores of critical thinking skills (286.83±17.44), professional identity (58.95±6.43), and professionalism (67.08±11.21) were significantly higher after the course than before the course ( P<0.001). Qualitative study identified the four themes of promoting effective learning, developing critical thinking and empathy, building professional attitudes, and expecting curriculum optimization. Conclusions:The "basic nursing" course based on signature pedagogy for undergraduate nursing students helps to enhance their critical thinking, foster a sense of professional identity, and develop professionalism.

Objective To investigate the predictive value of bone metabolism parameters on cardiac autonomic nervous system function in patients with type 2 diabetes mellitus(T2DM).Methods A total of 328 patients with T2DM hospitalized in the Department of Endocrinology of Gansu Provincial People's Hospital were enrolled in this study from October 2022 to October 2023.According to the serum 25(OH)D level,all the participants were divided into<10 ng/ml group(n=80),10～20 ng/ml group(n=173),and 20～30 ng/ml group(n=75).Biochemical indicators,bone metabolic parameters,left ventricular mass(LVM)and left ventricular mass index(LVMI)were compared.Time domain indicators ofheart rate variability(HRV)in 24 h holter electrocardiogram,including the global standard deviation of normal sinus RR interval(SDNN),sinus RR interval mean standard deviation(SDANN),and normal continuous sinus RR interval difference root mean square(RMSSD).Meanwhile,adjacent RR interval difference>50 ms as a percentage of the total inter-period(PNN50),HRV triangle index,standard deviation of the difference between the length of the entire adjacent NN interperiod(SDSD),and 24 h holter electrocardiogram HRV time-domain relevant indicators were compared among the three groups.The influence of bone metabolism parameters on cardiac autonomic nervous function and their correlation were analyzed,and the optimal cutting point of cardiac autonomic nervous function was predicted by receiver operating characteristic(ROC)curve.Results SBP,heart rate(HR),FPG,PWV,PTH and β-CTX in groups of 10 ng/ml,10～20 ng/ml and 20～30 ng/ml decreased in turn(P<0.05),while HDL-C,ABI,25(OH)D,Ca2+and PNN50 decreased.Correlation analysis between Spearman and Pearson showed that 25(OH)D was positively correlated with SDNN,HRV triangle index,PNN50 and rMSSD(P<0.01).Logistic regression analysis showed that 25(OH)D,Ca2+and HR were the influencing factors of cardiac autonomic nervous dysfunction in patients with T2DM.The ROC curve analysis showed that the areas under the ROC curve of 25(OH)D,Ca2+and HR were 0.791,0.607 and 0.629,respectively,with sensitivity of 73.4%,53.2%and 38.7%,and specificity of 74.0%,93.6%and 81.4%,respectively.Conclusions 25(OH)D is the influencing factor of cardiac autonomic nervous dysfunction in patients with T2DM,and patients with high degree of deficiency are more prone to cardiac autonomic nervous dysfunction.

Objective:To analyze the application of antitoxin therapy in severe infant botulism.Methods:A retrospective analysis was conducted on 14 cases of severe infant botulism treated at 3 pediatric medical centers from July 2020 to August 2024. This study investigated antitoxin dosage, treatment duration, discontinuation criteria and adverse reactions.Results:A total of 14 cases (12 males and 2 females) were included, with an age of 5.0 (3.8, 7.0) months. Botulinum toxin typing revealed 10 cases of Type B, 2 cases of Type A and 2 untyped cases. The interval from symptom onset to antitoxin administration was 9.0 (6.0, 11.5) d. The initial dosage of type A antitoxin was 12 500 (10 000, 22 500) U, while type B was 5 000 (5 000, 5 000) U. The dosage was tapered in some cases after symptom improvement, the duration of treatment was 16.5 (9.8, 25.3) d. In total, 11 infants discontinued medications after improvement in muscle strength, while 3 infants discontinued treatment after obtaining negative results from fecal mouse bioassays. Adverse events were reported in 2 cases, both of which resulted in rash, and 1 case was complicated with anaphylactic shock. All the patients survived upon discharge with a follow-up period of 11 d to 3 years and 8 months. Totally 12 infants had fully recovered, while 2 infants were still recovering after discharge.Conclusion:Antitoxin therapy is a feasible and safe approach which showed favorable prognosis in severe infant botulism.
