Objective:To analyze the prognostic value of systemic inflammatory score (SIS) in patients with unresectable stage Ⅲ non-small cell lung cancer (NSCLC) treated by definitive chemoradiotherapy (dCRT) combined with or without consolidation immunotherapy with immune checkpoint inhibitor (ICI).Methods:The medical record data of 229 patients who received dCRT from January 2014 to December 2017 and 183 patients who received dCRT combined with any form of ICI (induction, concurrent, consolidation or combination) from August 2018 to August 2022 in the Cancer Hospital, Chinese Academy of Medical Sciences were retrospectively analyzed. Upon admission, 1 and 3 months after treatment (efficacy evaluation) and upon tumor recurrence, peripheral blood count was collected, and neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and SIS were calculated, respectively. The SIS before, 1 and 3 months after treatment was defined as SIS 0, SIS 1 and SIS 3, respectively. Overall survival (OS) was considered as the primary endpoint. All patients were divided into dCRT group and dCRT+ICI group according to whether received immunotherapy, and then divided into different subgroups based on the cutoff value of SIS determined by X-Tile software. The prognostic value of SIS was evaluated by Kaplan-Meier survival analysis. The area under the receiver operating characteristic (ROC) curve (AUC) was used to evaluate the predictive efficiency. The predictive value of SIS was compared with inflammatory indexes (NLR, PLR) and independent prognostic factors. Results:In the dCRT group, the optimal cutoff value of SIS 0 was 590×10 9 and 530×10 9 in the dCRT+ICIs group. Univariate and multivariate analyses indicated that SIS 0 was an independent predictive factor of OS, progression - free survival (PFS), local - recurrence free survival (LRFS) and distant metastasis free survival (DMFS) in the dCRT group, but not associated with DMFS in the dCRT+ICI group. In the dCRT group, SIS 1>970×10 9 (optimal cutoff value) predicted poor OS ( HR=2.512, 95% CI=1.622-3.198, P<0.001), PFS ( HR=1.726, 95% CI=1.187-2.509, P=0.004), and DMFS ( HR=1.625, 95% CI=1.029-2.564, P=0.037). In the dCRT+ICI group, SIS 3>1570×10 9 (optimal cutoff value) indicated poor OS ( HR=5.107, 95% CI=1.731-15.069, P=0.003). In both groups, the AUC of SIS was higher than NLR, PLR and other traditional clinicopathological predictive indexes except T stage. Conclusions:SIS before treatment can be considered as an independent, dependable and easily acquired prognostic marker in patients with unresectable stage Ⅲ NSCLC treated by dCRT or dCRT+ICI. In the dCRT+ICI group, the optimal time point of post-radiotherapy SIS (3 months after treatment) is postponed than that (1 month after treatment) in the dCRT group.

Objective: To explore the potential classification of 24 hour activity time allocation among college students in Yinchuan and its association with active health levels, so as to provide references for optimizing activity time allocation to enhance active health levels. Methods: From November 18 to December 6, 2024, a stratified cluster random sampling method was used to select 2 422 first and second year college students from full time undergraduate institutions in Yinchuan. The Chinese College Students 24 hour Movement Behaviors Questionnaire (24 h MBQ) and Active Health Behavior Scale were used to assess 24 hour activity time allocation and evaluate active health levels. Latent profile analysis (LPA) was employed to categorize activity types, and a binary Logistic regression analysis was conducted to analyze the relationship between active health levels and activity types. Results: A total of 1 087 students (44.9%) were found of meeting active health standards, and significant statistical differences were found in active health levels across different genders, grades, academic qualities, sources of origin and academic categories ( χ 2= 22.03 , 7.65, 25.50, 10.12, 43.44, all P <0.01). Moreover, significant statistical differences could also be found among college students 24 hour activity time across different genders, ages, grades, sources of origin, academic qualities, and academic categories ( t/Z/H/F=-5.70-111.39, P <0.05).The 24 hour activity time allocation was classified into four types:academic high ( 6.9 %), low activity rest (8.8%), light activity (67.8%), and high activity dynamic (16.4%). Significant statistical differences were observed in activity time allocation categories across different ages, academic qualities and academic categories ( χ 2=15.52-108.46, all P <0.05). Using the high activity dynamic type as a reference, the light activity type ( OR=0.39, 95%CI =0.31-0.50), low activity rest type ( OR=0.10, 95%CI =0.06-0.15), and academic high type ( OR=0.03, 95%CI =0.02-0.07) had lower active health levels among college students (all P <0.01). Conclusion There is a significant difference in 24 hour activity time allocation among college students in Yinchuan, and different activity types are associated with active health levels.

Objective:To explore the effects and safety of Qigong Pills in IVF-ET outcome of PCOS infertility patients with phlegm-dampness type.Methods:A randomized controlled trial study was carried out. In the Reproductive and Genetic Medicine Center of Dalian Women and Children Medical Center (Group) from January 2021 to December 2023, 60 patients with sputum and damp-induced PCOS infertility assisted by in-vitro fertilization and embryo transfer (IVF-ET) were enrolled and randomly divided into 2 groups by block randomization method, with 30 cases in each group. Patients in both groups took ethinylestradiol cyproterone tablets orally on the 2nd to 5th day of the 1st menstrual cycle before IVF-ET cycle, and received down-regulation treatment on the 18th to 20th day of menstruation. After confirming that the down-regulation standard was reached, Qigong Pills was added to the treatment group, and placebo was taken orally until the trigger day. Two groups of patients underwent transvaginal ultrasound-guided ovarian aspiration after injection of chorionic gonadotropin (hCG) for 24-36 h. The total amount of Gn, the days of Gn, the endometrial thickness of HCG, the number of eggs obtained, the rate of diprokaryotic (2PN) fertilization, the number of transferable embryos, the number of high-quality embryos, the rate of high-quality embryos, the incidence of OHSS and the clinical pregnancy rate were compared between the two groups.Results:Among the 60 patients, 28 cases in the final treatment group and 27 cases in the control group were included in the outcome index evaluation. During controlled hyperstimulation (COH), the total Gn [2 025 (1 575, 2 325) U vs. 2 700 (2 025, 3 150) U, Z=-3.67] and the number of Gn days of the treatment group [10 (8,11) d vs. 11 (9,13) d, Z=-2.31] were lower than those in control group ( P<0.001 or P<0.05). There was no statistical significance in endometrial thickness between 2 groups on HCG day ( P>0.05); the number of high-quality embryos [3 (3, 4) vs. 2 (2, 3), Z=0.11] and the rate of high-quality embryos [46.28% (87/188) vs. 35.19% (57/162), Z=4.42] in the treatment group were higher than those in the control group ( P<0.05). There was no statistical significance in the number of eggs obtained, the fertilization rate of 2PN and the number of transferable embryos between the two groups ( P>0.05). The incidence of OHSS was 3.6% (1/28) in the treatment group and 11.1% (3/27) in the control group, without statistical significance ( P=0.352). The clinical pregnancy rate was 53.6% (15/28) in the treatment group and 37.0% (10/27) in the control group, without statistical significance ( P=0.218). There was no significant difference in the safety indexes of liver and kidney function between 2 groups ( P>0.05). Conclusion:Qigong Pills combined with IVF-ET can effectively reduce the total amount of Gn and the number of days of treatment in PCOS infertility patients with phlegm-dampness type, increase the number and rate of high-quality embryos, and improve the outcome of IVF-ET, and it is safe and effective.

Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective To investigate the impact of variations in RNA-binding motif protein 20(RBM20)and muscle-restricted coiled-coil(MURC)digenic heterozygosity variation on the structural and biological characteristics of human cardiomyocyte AC 16(an adult left ventricular myocardial cell line).Methods Cardiomyocyte AC 16 cell lines were constructed with control,negative scramble,wild-type,MURC single-gene mutant,RBM20 single-gene mutant,and RBM20 and MURC digenic mutant groups.The localization of RBM20 and MURC in cardiomyocytes,cell area,cytoskeletal arrangement,cytoskeleton-related proteins,cell polarity,and intracellular calcium concentration were observed using Western blotting,immunofluorescence staining,and reverse transcription polymerase chain reaction.Myocardial apoptosis was detected using flow cytometry.Ki-67 staining and wound healing assays were performed to detect cardiomyo-cyte proliferation and migration,respectively.Results Digenic mutations had a more pronounced impact than single-gene mutations in RBM20 or MURC on the structural and biological characteristics of cardiomyocytes,manifested by increased cell area,upregulated mRNA expression of hypertrophy-related genes,such as myosin heavy chain 7 and alpha-actin,increased cytoskeleton disturbance,decreased flu-orescence intensity of cytoskeletal proteins β-tubulin and Vinculin(all P＜0.01);increased fluorescence intensity of the polarity protein Part 6(P＜0.05);and significantly elevated cardiomyocyte apoptosis rate,decreased proliferative activity,and elevated migration rate and intracellular calcium ion concentration(all P＜0.01).Conclusion The digenic heterozygous variation in RBM20 and MURC may induce changes in the morphological structure and biological characteristics of myocardial cells,including increased cell area,cytoskeleton dis-turbance,cell polarity,increased apoptosis rate and mobility,decreased cell proliferation activity,and calcium processing ability.
