Background: Adrenocortical hormones, particularly 11-oxygenated androgens, are pivotal in female reproductive health and fertility. Standardized detection kits and population-specific reference intervals are lacking in China, hindering related clinical applications. Methods: A HPLC-tandem mass spectrometry (HPLC-MS/MS) pipeline was developed, rigorously validated, and applied to simultaneously quantify corticosterone, cortisone, cortisol, 18-OH cortisol, androstenedione (A4), 11β-hydroxyandrostenedione (11-OH A4), dehydroepiandrosterone, and dehydroepiandrosterone sulfate in serum samples from 455 reproductive-aged women (18–45 yrs) in Guangxi, China. Age-dependent concentration trends were analyzed, and reference intervals stratified by age (2.5th to 97.5th percentiles) were established. Correlations with body-composition metrics, ethnicity, and the menstrual cycle were investigated. Results: The HPLC-MS/MS method demonstrated high precision (intra- and inter-assay CVs < 15%), accuracy, and sensitivity. All eight hormones exhibited significant age-related declines (P < 0.001 for seven hormones; P = 0.001 for 11-OH A4). Notably, 11-OH A4 levels were significantly lower in the 35–45-yr (3.05 nmol/L) and 25–34-yr (3.09 nmol/L) age groups than in the 18–24-yr (3.57 nmol/L) age group, whereas no significant difference was observed between the 35–45-yr and 25–34-yr age groups. Weak negative correlations were observed between the body mass index and corticosterone and cortisone levels, whereas ethnicity and the menstrual cycle showed no significant associations with hormone levels. Conclusions We developed an HPLC-MS/MS-based method for simultaneously quantifying eight adrenocortical hormones, including 11-OH A4, and defined age-specific reference intervals for reproductive-aged Chinese women. These findings advance the clinical utility of adrenocortical hormones in diagnosing and managing reproductive disorders.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective:To investigate the relationship between different states of cardiac function and their changes during the course of diabetic foot ulcers(DFU), and to evaluate their impact on patient prognosis.Methods:A retrospective analysis was conducted on 194 DFU patients who were rehospitalized at approximately 3-month intervals. Basic clinical data and cardiac function-related indicators were collected at baseline and follow-up. Patients were followed until death or until November 10, 2024. Outcomes including ulcer healing, recurrence, minor amputation, and death were recorded. Logistic regression models were used to analyze the effects of cardiac function status and its changes on these four outcomes. Results:After treatment, the proportion of patients with NYHA class Ⅱ-Ⅲ decreased significantly from 33.5% at baseline to 21.6%( P=0.009). Serum N-terminal pro-B-type natriuretic peptide(NT-proBNP) level also decreased after treatment compared with baseline [635.85(59.83, 453.28) pg/mL vs 728.67(81.48, 696.15) pg/mL, P=0.055]. Serum NT-proBNP level was significantly higher in the death group compared to the survival group( P=0.002). The proportion of DFU patients with baseline NYHA class Ⅱ-Ⅲ was significantly higher than that in those with class Ⅰ( P=0.012). Regression analysis showed that an improvement in NT-proBNP levels was associated with a lower risk of DFU recurrence( OR=0.378, 95% CI 0.183-0.779, P=0.008), and improvement in NYHA class was associated with a lower mortality risk( OR=0.074, 95% CI 0.020-0.275, P<0.001). Conclusion:Cardiac function status and its changes during the treatment of DFU patients have strong prognostic implications, particularly in predicting the risk of recurrence and death outcomes.

Objective To investigate the safety and effectiveness of endovascular treatment in patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)over 24 h after onset.Methods The clinical data of AIS-LVO patients who received endovascular treatment in Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2022 were retrospectively analyzed,including baseline characteristics,imaging findings,treatment,degree of vascular recanalization(modified thrombolysis in cerebral infarction grade 2b and 3 for successful recanalization)and prognosis.Results A total of 57 patients were included,including 42 males and 15 females,aged from 30 to 84 years old.The most common risk factors were hypertension(39 cases,68.4%),followed by smoking history(24 cases,42.1%),diabetes mellitus(17 cases,29.8%),previous stroke history(16 cases,28.1%),and atrial fibrillation(9 cases,15.8%).Before treatment,the National Institutes of Health stroke scale score was 12.84±7.04,and the Alberta Stroke Program early computed tomography score was 9.00(7.00,10.00).Vascular occlusion sites included middle cerebral artery occlusion in 27(47.4%)cases,internal carotid artery occlusion in 24(42.1%)cases,and tandem lesions in 6(10.5%)cases.The time from onset to femoral artery puncture was 38.30(28.17,53.71)h,and the time from femoral artery puncture to vascular recanalization was 52.00(38.50,92.50)min.General anesthesia was the main anesthesia method,accounting for 64.9%(37/57).The etiological types of stroke were mainly large artery atherosclerosis(38 cases,66.7%),cardiogenic embolism(9 cases,15.8%),unknown causes(6 cases,10.5%),and other clear causes(4 cases,7.0%).Mechanical thrombectomy was the first choice in 41(71.9%)cases,balloon dilatation/stenting was used in 35(61.4%)cases,of which 15(26.3%)cases were the first choice.Finally,53(93.0%)cases were recanalized successfully.In terms of complications,1(1.8%)case had symptomatic intracranial hemorrhage.The 90-d prognosis rate was 59.6%(34/57),and 3(5.3%)cases died.Conclusion Endovascular treatment for AIS-LVO patients over 24 h after onset has high recanalization rate and good safety,but it still needs to be further verified by randomized controlled trials.

Objective To explore the five-circuit and six-qi features of birth time and onset time of children with acute lymphoblastic leukemia(ALL).Methods A total of 877 cases of children with ALL from Children's Hospital of Soochow University from June 2021 to February 2023 were collected,and their five-circuit and six-qi features of birth time and onset time were analyzed.And then the correlation of five-circuit and six-qi features of birth time and onset time with ALL was explored preliminarily,and the pathogenic characteristics of congenital factors and acquired pathogenic factors were revealed.Results(1)The children who were born in the year with the heavenly stems being bing(the 3rd of the ten heavenly stems)and ding(the 4th of the ten heavenly stems)and with the earthly branches being shen(the 8th of the twelve earthly branches)and you(the 9th of the twelve earthly branches)are prone to suffer from ALL,and the birth year of children with ALL had the five-circuit and six-qi features of the joining of guest circuit with dominant circuit being rebellious.ALL is commonly seen in the year with the heavenly stems being geng(the 7th of the ten heavenly stems)and xin(the 8th of the ten heavenly stems)and with the earthly branches being zi(the 1st of the twelve earthly branches)and chou(the 2nd of the twelve earthly branches),and the onset year of ALL in children had the five-circuit and six-qi features of the yearly circuit being gold-circuit and water-circuit,sitian-zaiquan yearly circuit qi being shaoyin monarch-fire with yangming dryness-gold,taiyin damp-earth with taiyang cold-water,and the qi-circuit assimilation relationship being celestial correspondence,same celestial correspondence,celestial correspondence in convergent year,disharmony,mildly-rebellious,and celestial restriction.Conclusion Gold-dryness and water-cold are the congenital factors and acquired pathogenic factors of ALL.The onset of ALL in children is closely related to qi insufficiency and qi stagnation of wood and fire in five-circuit and six-qi theory.

ObjectiveTo investigate the mechanism by which Feixin decoction treats hypoxic pulmonary hypertension （HPH） by regulating the peroxisome proliferator-activated receptor gamma （PPARγ）/nuclear factor-kappa B （NF-κB）/NOD-like receptor pyrin domain containing 3 （NLRP3） signaling pathway. MethodsForty-eight male SD rats were randomly allocated into normal， hypoxia， and low-， medium- and high-dose （5.85， 11.7， 23.4 g·kg^-1， respectively） Feixin decoction groups， with 8 rats in each group. Except the normal group， the remaining five groups were placed in a hypoxia chamber with an oxygen concentration of （10.0±0.5）% for 8 h per day， 28 days， and administrated with corresponding drugs during the modeling process. After 4 weeks of treatment， echocardiographic parameters ［pulmonary artery acceleration time （PAT）， pulmonary artery ejection time （PET）， right ventricular anterior wall thickness （RVAWd）， and tricuspid annular plane systolic excursion （TAPSE）］ were measured for each group. The right ventricular systolic pressure （RVSP） was measured by the right heart catheterization method， and the right ventricular hypertrophy index （RVHI） was calculated by weighing the heart. The pathological changes in pulmonary arterioles were observed by hematoxylin-eosin staining. The co-localization of α-smooth muscle actin （α-SMA） with NLRP3， N-terminal gasdermin D （N-GSDMD）， and cysteinyl aspartate-specific proteinase-1 （Caspase-1） in pulmonary arteries was detected by immunofluorescence. The protein levels of PPARγ， NF-κB， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， N-GSDMD， interleukin-1β （IL-1β）， interleukin-18（IL-18）， and cleaved Caspase-1 in the lung tissue was determined by Western blot. The ultrastructural changes in pulmonary artery smooth muscle cells （PASMCs） were observed by transmission electron microscopy. ResultsCompared with the normal group， the hypoxia group showed increased RVSP and RVHI （P<0.01）， decreased right heart function （P<0.01）， increased pulmonary vascular remodeling （P<0.01）， increased co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 in pulmonary arterioles （P<0.01）， up-regulated protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， a down-regulated protein level of PPARγ （P<0.05， P<0.01）， and pyroptosis in PASMCs. Compared with the hypoxia group， Feixin decoction reduced RVSP and RVHI， improved the right heart function and ameliorated pulmonary vascular remodeling （P<0.05， P<0.01）， decreased the co-localization of α-SMA with NLRP3， N-GSDMD， and Caspase-1 （P<0.05， P<0.01）， down-regulated the protein levels of NF-κB， NLRP3， ASC， N-GSDMD， IL-1β， IL-18， and cleaved Caspase-1 in the lung tissue （P<0.05， P<0.01）， up-regulated the protein level of PPARγ （P<0.05， P<0.01）， and alleviated pyroptosis in PASMCs. ConclusionFeixin decoction can ameliorate pulmonary vascular remodeling and right heart dysfunction in chronically induced HPH rats by regulating pyroptosis in PASMCs through the PPARγ/NF-κB/NLRP3 pathway.

Objective:To investigate the epidemiological characteristics and morbidity trends of hypertensive disorders of pregnancy (HDP) in Shenzhen, China.Methods:This study was a cross-sectional study. Data were based on the Shenzhen Birth Cohort. Pregnant women who gave birth from January 1, 2018 to March 31, 2023 were included. Incidence and change trends of HDP and its different pathological types were analyzed. The enrolled pregnant women were divided into the HDP group and the non-HDP group according to whether HDP occurred. General clinical data and pregnancy outcomes were collected from both groups. The incidence of adverse pregnancy outcomes among pregnant women with different pathological types of HDP was analyzed, and subgroup analyses were performed based on age and body mass index (BMI).Results:A total of 90 117 pregnant women were enrolled, aged (31.6±4.4) years. There were 4 117 cases in the HDP group and 86 000 in the non-HDP group. The overall incidence of HDP in the whole study population was 4.57% (4 117/90 117). From 2018—2023, the incidence of HDP in Shenzhen showed an increasing trend year by year, from 2.88% (523/18 155) to 7.04% (271/3 851). Specifically, the incidence of gestational hypertension increased from 0.93% (168/18 155) to 3.09% (119/3 851), the incidence of preeclampsia-eclampsia increased from 1.78% (323/18 155) to 3.17% (122/3 851), the incidence of chronic hypertension increased from 0.01% (1/18 155) to 0.42% (16/3 851), and the incidence of chronic hypertension with superimposed preeclampsia increased from 0.17% (31/18 155) to 0.36% (14/3 851). The age ((32.8±4.8) years vs. (31.5±4.3) years, P<0.05) and BMI in the first trimester ((23.37±3.77) kg/m 2 vs. (21.35±2.91) kg/m 2, P<0.05) of HDP group were higher than those of the non-HDP group. Subgroup analysis showed that the incidence of HDP in pregnant women aged≥50.0 years was the highest in all age subgroups (42.86% (6/14)). The incidence of HDP in pregnant women with BMI≥30.0 kg/m 2 in the first trimester was the highest among all BMI subgroups (20.44% (241/1 179)). The proportions of preterm birth, gestational diabetes, fetal growth restriction, small for gestational age, placental abruption, and late abortion in HDP group were 30.82% (1 269/4 117), 30.46% (1 254/4 117), 6.80% (280/4 117), 4.86% (200/4 117), 3.59% (148/4 117), and 0.80% (33/4 117), respectively. Conclusions:The incidence of HDP among pregnant women has been increased year by year in Shenzhen, China. With the increase in age and BMI during early pregnancy, the incidence of HDP showed an overall upward trend.

Objective To explore the relationship between triglyceride-glucose index(TyG)and acute ischemic stroke with large vessel occlusion(AIS-LVO)of anterior circulation.Methods A retrospective study was conducted on patients with anterior circulation AIS-LVO who underwent emergency endovascular thrombectomy at Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2019.According to modified Rankin scale(mRS)score 90 d after operation,the patients were assigned to favorable outcome group(mRS score 0-2)or unfavorable outcome group(mRS score 3-6),and the TyG was compared.According to the median of TyG,the patients were assigned to low-TyG group(TyG＜8.57)or high-TyG group(TyG ≥8.57),and the clinical data,laboratory indexes,and imaging characteristics were compared.Receiver operating characteristic curve was used to evaluate the predictive value of TyG for poor prognosis.Results A total of 135 patients were enrolled,with 72 in the favorable outcome group and 63 in the unfavorable outcome group.The TyG of the unfavorable outcome group was significantly higher than that of the favorable outcome group(8.82+0.63 vs 8.43+0.60,P＜0.001).There were 67 patients in the low-TyG group and 68 in the high-TyG group.Compared with the low-TyG group,the proportion of patients with hyperlipidemia history(P=0.003),systolic blood pressure at admission(P=0.018),fasting blood glucose level(P＜0.001),and triglyceride level(P＜0.001)were significantly higher in the high-TyG group,the infarct core volume was significantly larger(P=0.025),the high density lipoprotein-cholesterol level was significantly lower(P=0.013),and the mRS score 90 d after operation was significantly higher(3[1,5]vs 1[0,5],P=0.049).The TyG had certain predictive value for poor prognosis in anterior circulation AIS-LVO patients(area under curve value=0.662,95％confidence interval 0.571-0.753).Conclusion TyG is elevated in anterior circulation AIS-LVO patients with poor prognosis,and may be a potential prognostic indicator for anterior circulation AIS-LVO patients.
