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.

ObjectiveTo investigate the mechanism by which Sini San (SNS) treats liver fibrosis through regulating the polarization of intrahepatic Kupffer cells. MethodsSixty SPF-grade male Balb/c mice were randomized into blank control, model, silymarin (0.2 g·kg-1), and low-, medium-, and high-dose (2.93, 5.85, 11.70 g·kg-1, respectively) SNS groups. A mouse model of liver fibrosis was induced by intraperitoneal injection of CCl4. After 5 weeks of administration, the body mass, liver pathological changes [Hematoxylin and Eosin (HE), Masson, and Sirius red staining], serum biochemical indicators [alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT)], liver fibrosis markers [procollagen type Ⅲ (PCⅢ), laminin (LN), and hyaluronic acid (HA)], inflammatory cytokines [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and interleukin-10 (IL-10)], and fibrosis-related proteins [α-smooth muscle actin (α-SMA), collagen type Ⅰ (Col Ⅰ), and collagen type Ⅲ (Col Ⅲ)] were assessed. A co-culture system of THP-1 cells (M1 macrophages) and human hepatic stellate cells (LX-2) was established. The cell experiment was designed with blank control (LX-2 alone), model (LX-2 + M1 macrophages), and low-, medium-, and high-dose SNS (co-culture with 5%, 10%, or 20% SNS-containing serum, respectively) groups. Cell viability, inflammatory cytokines, and macrophage phenotype were examined. Human primary hepatic Kupffer cells were allocated into blank control, M1 (LPS 100 μg·L-1+IFN-γ 20 μg·L-1), M2 (IL-4 20 μg·L-1+IL-13 20 μg·L-1), M1+M2, M1+SNS (supplemented with 10% SNS-containing serum for 2 h after culture under M1 conditions for 24 h), M2+SNS (supplemented with 10% SNS-containing serum for 2 h after culture under M2 conditions for 24 h), and M1+M2+SNS groups (supplemented with 10% SNS-containing serum for 2 h after culture under M1+M2 conditions for 24 h), and the expression of nuclear factor-κB (NF-κB) p65 and signal transducer and activator of transcription 3 (STAT3) at protein and mRNA levels was determined. ResultsCompared with the blank group, the model group exhibited increased serum levels of ALT, AST, ALP, PCⅢ, LN, HA, IL-6, and TNF-α, upregulated protein and mRNA levels of α-SMA, Col Ⅰ, and Col Ⅲ in the liver tissue (P<0.05, P<0.01), and decreased IL-10 level and STAT3 mRNA level (P<0.05, P<0.01), accompanied by marked collagen deposition and inflammatory infiltration in the liver. Compared with the model group, all doses of Sini San reversed these alterations (P<0.05, P<0.01), with the high-dose group showing the most pronounced effects. Cell experiments demonstrated that, compared with the blank control group, the model group had elevated levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α) and upregulated protein and mRNA levels of M1 markers [cluster of differentiation 86 (CD86, inducible nitric oxide synthase (iNOS), and monocyte chemoattractant protein-1 (MCP-1)] (P<0.01), along with declined level of IL-10 and downregulated expression of M2 markers [(CD163, CD206, and arginase-1 (Arg-1)] (P<0.05,P<0.01). Compared with the model group, treatment with Sini San-containing serum at various concentrations lowered the levels of pro-inflammatory cytokines and expression of M1 markers (P<0.05, P<0.01), while increasing the IL-10 level and M2 marker expression (P<0.05, P<0.01). Additionally, Sini San downregulated the mRNA level of NF-κB and upregulated the mRNA level of STAT (P<0.05, P<0.01). In the experiment with human primary Kupffer cells, compared with the blank group, the M1 group showed increased NF-κB p65 expression (P<0.01) and decreased STAT3 expression (P<0.05), whereas the M2 group exhibited increased STAT3 expression (P<0.01). Compared with the respective model groups, Sini San-containing serum reversed the M1-induced overexpression of NF-κB p65 (P<0.05, P<0.01) and further enhanced the M2-induced STAT3 expression (P<0.05, P<0.01). ConclusionSini San can inhibit the NF-κB p65/STAT3 signaling pathway and repolarize intrahepatic Kupffer cells from the pro-inflammatory M1 to the anti-inflammatory M2 phenotype to attenuate inflammation and suppress hepatic stellate cell activation and collagen deposition, thereby exerting anti-fibrotic effect.

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.

This paper reports a case of a patient with sleep-related painful erections treated by acupuncture combined with abdominal vibration therapy. The main symptom was repeated painful penile erections during nighttime sleep. The syndrome was differentiated as "water failing to nourish wood" and "liver qi stagnation". Acupuncture was applied at Baihui (GV20), Sishencong (EX-HN1), Guanyuan (CV4), and bilateral Neiguan (PC6), Hegu (LI4), Taichong (LR3), Taixi (KI3), Guilai (ST29), Yongquan (KI1), Yanglingquan (GB34), and Sanyinjiao (SP6). The treatment was combined with abdominal vibration therapy. Treatment was given once daily, five times per week. After the first treatment, the severity and duration of nocturnal erection pain were reduced, and sleep quality was improved. After two weeks of treatment, nocturnal erection pain persisted but became tolerable, with significantly shortened duration.

BACKGROUND:
To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study.
METHODS:
This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well.
RESULTS:
The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β <0, P <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed.
CONCLUSIONS:
The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required.

Objective:To compare the efficacy and safety of continuous venetoclax combined azacitidine (VA) chemotherapy and intermedium/high-dose cytarabine (I/HDAC) consolidation in patients with acute myeloid leukemia (AML) fit for standard chemotherapy (transform from UNFIT) .Methods:Clinical data of patients who were fit for standard chemotherapy were collected among those with AML who underwent VA induction in the Department of Hematology, the Second Hospital of Hebei Medical University. The overall survival (OS), relapse-free survival (RFS), event-free survival (EFS), and incidence of adverse events were analyzed retrospectively.Results:This study enrolled 69 patients, consisting of 46 cases in the VA group and 23 cases in the I/HDAC group. We revealed the following. ① The median OS, RFS, EFS were 26.18, 24.69, 20.34 months in the VA group, and 34.14, 30.99, 28.42 months in the I/HDAC group, respectively, with no statistically significant difference (all P>0.05). Median OS of patients who underwent I/HDAC consolidation with European Leukemia Net (ELN) favorable-risk, positive measurable residual disease (MRD), wild type FLT3, or IDH1/2 mutation was significantly longer than those who received VA ( P<0.05). ②Adverse events rate of grade 3 - 4 neutropenia, grade 3 - 4 thrombocytopenia, and bacteremia were significantly lower in the VA group than in the I/HDAC group ( P<0.05) . Conclusions:I/HDAC consolidation was more likely to help get survival benefits for patients with ELN favorable-risk, positive MRD, wild type FLT3, or IDH1/2 mutation. Continuous VA chemotherapy exhibited superior safety than I/HDAC consolidation.

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.
