OBJECTIVE To investigate the effects and mechanisms of Buyang huanwu decoction (BYHWD) and its active fractions in ameliorating non-alcoholic fatty liver disease. METHODS BYHWD and its effective fractions obtained through ethanol precipitation, as well as 30% ethanol, 50% ethanol, and 75% ethanol fractions (namely, the CC effective fraction, 30YC effective fraction, 50YC effective fraction, and 75YC effective fraction), were prepared. These preparations were administered to rats via intragastric administration to prepare corresponding drug-containing serum (blank serum and simvastatin-containing serum were prepared using the same protocol). Human L02 hepatocytes were divided into control group, model group, simvastatin-containing serum group, BYHWD-containing serum group, CC-containing serum group, 30YC-containing serum group, 50YC-containing serum group, and 75YC-containing serum group. Except for the control group, other groups were given 0.2 mol/L oleic acid for 24 h to induce a lipid accumulation model, and then intervened with 20% drug-containing serum/blank serum for 24 h. The lipid deposition in cells was observed, and the proportion of lipid droplet area was calculated; the levels of triglycerides (TG) and indicators of oxidative stress [malondialdehyde (MDA), superoxide dismutase (SOD)] as well as liver function [alanine amino- transferase (ALT), aspartate amino-transferase (AST)] in cells were detected; protein and mRNA expressions of AMP-activated protein kinase (AMPK)/sterol regulatory element-binding protein-1 (SREBP-1)/glycerol-3-phosphate acyltransferase (GPAT) signaling pathway were also measured. RESULTS Compared with the control group, cells in the model group exhibited severe cellular steatosis, with a significantly increased proportion of lipid droplet area, as well as the elevated levels of TG, ALT, AST, and MDA in cells, along with significantly up-regulated mRNA and protein expression levels of SREBP-1 and GPAT (P<0.05). The level of SOD, mRNA expression of AMPK, as well as the protein phosphorylation level of AMPK were decreased significantly (P<0.05). Compared with the model group, cellular steatosis was alleviated in all drug-containing serum groups, and the levels of most of the aforementioned quantitative indicators were significantly reversed (P<0.05). CONCLUSIONS BYHWD and its active fractions can exert a therapeutic effect on improving non-alcoholic fatty liver disease by regulating the AMPK/SREBP-1/GPAT signaling pathway, inhibiting oxidative stress responses, and reducing lipid deposition.

Objective:
To investigate the prevalence and influencing factors of the co-occurrence of elevated blood pressure and depressive symptoms among junior and senior high school students in Anhui Province, so as to provide evidence for comprehensive interventions on physical and mental health among adolescents.
Methods:
From September to December 2024, a multi stage random cluster sampling method was used to select 103 225 junior and senior high school students from 16 prefecture level cities in Anhui Province. Data were collected through questionnaire surveys and physical measurements. Elevated blood pressure was determined according to the Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years. Depressive symptoms among middle school students were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Chi-square test, Chi-square test for trend, and multivariate Logistic regression model were used to analyze the risk factors for the co-occurrence of elevated blood pressure and depressive symptoms.
Results:
The detection rate of elevated blood pressure was 15.22%, the detection rate of depressive symptoms was 18.56%, and the co-occurrence rate of the two conditions was 2.67% among junior and senior high school students. Multivariate Logistic regression analysis showed that after controlling for gender, school stage, household registration, and overweight and obesity status,compared with those who don t drink sugary drink and eat fried food, and get enough sleep, sugar sweetened beverage intake <1 and ≥1 time/d( OR =1.28,1.61), fried food consumption ≥1 time/d( OR =1.37), and insufficient sleep ( OR =1.54) were all associated with an increased risk of the co-occurrence of elevated blood pressure and depressive symptoms(all P <0.05). Daily fresh vegetable intake ≥1 time/d( OR =0.78) and fresh fruit intake ≥1 time/d( OR =0.85) were both associated with a decreased risk of the co-occurrence(both P <0.05). Compared with students who did not eat breakfast, students who ate breakfast sometimes and every day ( OR =0.62,0.36) had a lower co-occurrence risk(both P < 0.05). Junior and senior high school students with daily outdoor activity duration≥1 h ( OR =0.81) had a lower risk of the co-occurrence of elevated blood pressure and depressive symptoms ( P <0.05).
Conclusions
Sugar sweetened beverage drink and fried food consumption, inadequate consumption of fresh vegetables, fruits and breakfast, lack of outdoor activity, and insufficient sleep are risk factors for the co-occurrence of elevated blood pressure and depressive symptoms among junior and senior high school students in Anhui Province. It is necessary to establish school health promotion strategies integrating nutrition, exercise and sleep management as intervention targets to reduce the co-occurrence risk of elevated blood pressure and depressive symptoms among junior and senior high school students.

OBJECTIVE To investigate the clinical characteristics of euglycemic diabetic ketoacidosis (euDKA) induced by empagliflozin, and provide references for safe medication. METHODS Case reports of euDKA induced by empagliflozin were retrieved and analyzed from PubMed, Web of Science, CNKI, and Wanfang Data. The Naranjo’s scale was adopted to assess the causal relationship between empagliflozin and euDKA. RESULTS A total of 29 patients were enrolled, including 16 males and 13 females,with a median age of 58 years. All patients were diagnosed with type 2 diabetes mellitus; 22 patients had at least one comorbidity. The median time to euDKA onset was 60 days after administration, and 7 cases occurred within 2 weeks of treatment. Perioperative periods,fasting,and low-carbohydrate or ketogenic diets were the main predisposing factors. Common presentations included nausea,vomiting, fatigue, tachypnea,and tachycardia. The causal relationship between empagliflozin and euDKA was assessed as “probable” in all cases. According to adverse reaction severity grading, 13 cases were grade 3 (severe) and 16 cases were grade 4 (life-threatening). All patients discontinued empagliflozin and recovered after corresponding treatment. CONCLUSIONS euDKA is a serious adverse reaction to empagliflozin, which mostly occurs early in treatment. Perioperative periods, fasting, and ketogenic diets are prone to induce euDKA. Elderly patients and those with comorbidities are at higher risk. Risk assessment should be conducted before clinical administration; blood ketones and acid-base monitoring should be strengthened in the early medication period; withhold the drug before elective surgery, avoid prolonged fasting;upon diagnosis, discontinue empagliflozin and initiate intravenous insulin, provide fluid resuscitation promptly, and use other treatments to improve patient prognosis.

ObjectiveTo explore the effectiveness and safety of Shenlong Dingji Formula (参龙定悸方) on the quality of life in patients with paroxysmal atrial fibrillation (PAF) of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome. MethodsA total of 60 patients with PAF of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome were recruited and randomly divided into a treatment group and a control group, with 30 patients in each group. The control group received standard western medicine treatment, while the treatment group was additionally given Shenlong Dingji Formula orally, one dose per day. Both groups were treated for 4 weeks. The primary outcome measure is the Atrial Fibrillation Effect on Quality of Life (AFEQT) score including scores of four dimensions,i.e. atrial fibrillation-related symptoms, treatment concerns, daily activities, and treatment satisfaction. The secondary outcome measures included the frequency and duration of symptomatic atrial fibrillation episodes and traditional Chinese medicine (TCM) syndrome scores covering symptoms such as palpitations, chest tightness, fatigue, shortness of breath, reluctance to speak, spontaneous sweating, stabbing pain, and insomnia. These indicators were assessed at baseline (before treatment), after 2-week of treatment, after 4-week of treatment, and 4 weeks after the end of treatment (follow-up). Additionally, safety indicators before and after treatment and adverse events occurring during the trial were recorded to evaluate safety. ResultsA total of 56 patients completed the study, with 28 in each group. Primary outcome indicators: 1) the treatment group showed significant improvement in the total score of the AFEQT scale, with significantly higher total scores after 2-week treatment, 4-week treatment, and follow-up compared to the previous time point (P<0.05). In the control group, the AFEQT score significantly increased only after 4-week treatment compared to baseline (P<0.05). In the treatment group, the AFEQT scores after 2-week, 4-week treatment, and during follow-up were all higher than those of the control group at the corresponding time points (P<0.01). 2) In the treatment group, there was no statistically significant difference in the AFEQT treatment satisfaction dimension score during follow-up compared to that after 4-week treatment (P>0.05). However, the scores for all other dimensions at each time point were higher than those at the previous time point (P<0.05). In the control group, the scores for the atrial fibrillation-related symptom dimension were higher after 2-week and 4-week treatment than those of the previous time points (P<0.05). For the treatment satisfaction dimension, significant increases were observed only after 2-week and 4-week treatment compared to baseline (P<0.05). Secondary outcome indicators: 1) In the treatment group, the frequency and duration of symptomatic atrial fibrillation episodes decreased significantly at each time point compared to the previous time point (P<0.05), except for the duration of trial fibrillation at follow-up. In the control group, the frequency of episodes decreased significantly at all time points compared to baseline (P<0.05), while the duration of trial fibrillation showed a significant reduction at follow-up compared to those after 2-week treatment (P<0.05). 2) In the treatment group, TCM syndrome scores significantly reduced after 2-week treatment, 4-week treatment, and during follow-up compared to the previous time point and baseline (P<0.05). In the control group, significant reductions were observed only after 4-week after treatment and during follow-up (P<0.05). The TCM syndrome scores in the treatment group were lower than those in the control group at the same time points (P<0.01). No adverse events occurred during the trial in either group, and safety indicators showed no significant changes after treatment. ConclusionShenlong Dingji Formula effectively improves the quality of life, alleviates TCM syndromes, and reduces the frequency and duration of symptomatic atrial fibrillation in patients with PAF of qi-yin deficiency and phlegm-stasis obstructing collaterals syndrome, and demonstrates good safety.

ObjectiveTo explore the mechanism by which Buyang Huanwutang regulates the glutathione peroxidase 4 (GPX4)-acyl-CoA synthetase long-chain family member 4 (ACSL4) axis to inhibit ferroptosis and promote neurological functional recovery after spinal cord injury (SCI). MethodsNinety rats were randomly divided into five groups: sham operation group, model group, low-dose Buyang Huanwutang group (12.5 g·kg-1), high-dose Buyang Huanwutang group (25 g·kg-1), and Buyang Huanwutang + inhibitor group (25 g·kg-1 + 5 g·kg-1 RSL3). The SCI model was established by using the allen method. Tissue was collected on the 7th and 28th days after operation. Motor function was assessed by using the Basso-Beattie-Bresnahan (BBB) scale. Hematoxylin-eosin (HE), Nissl, and Luxol fast blue (LFB) staining were performed to observe spinal cord histopathology. Transmission electron microscopy was used to examine mitochondrial ultrastructure. Immunofluorescence staining was used to detect the number of NeuN-positive cells and the fluorescence intensity of myelin basic protein (MBP), GPX4, and ACSL4. Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) was used to analyze the mRNA expression of GPX4 and ACSL4. Enzyme linked immunosorbent assay (ELISA) was performed to measure the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD). Colorimetric assays were used to determine the iron content in spinal cord tissue. ResultsCompared to the sham operation group, the model group exhibited significantly reduced BBB scores (P<0.01), severe pathological damage in spinal cord tissue, and marked mitochondrial ultrastructural disruption. In addition, the model group showed a decrease in the number of NeuN-positive cells (P<0.01), reduced fluorescence intensity of MBP and GPX4 (P<0.01), lower levels of GSH and SOD (P<0.01), and downregulated mRNA expression of GPX4 (P<0.01). Moreover, compared to the sham operation group, the model group had elevated levels of ROS, MDA, and tissue iron content (P<0.01), along with increased fluorescence intensity and mRNA expression of ACSL4 (P<0.01). Compared with the model group and Buyang Huanwutang + inhibitor group, the Buyang Huanwutang group showed significantly improved BBB scores (P<0.05, P<0.01) and exhibited less severe spinal cord tissue damage, reduced edema and inflammatory cell infiltration, increased neuronal survival, and more intact myelin structures. Additionally, mitochondrial ultrastructure was significantly improved in the Buyang Huanwutang group. Compared to the model group and Buyang Huanwutang + inhibitor group, the Buyang Huanwutang group significantly increased the number of NeuN-positive cells and the fluorescence intensity of MBP (P<0.05, P<0.01). Furthermore, Buyang Huanwutang significantly increased the fluorescence intensity and mRNA expression of GPX4 (P<0.01) and decreased the fluorescence intensity and mRNA expression of ACSL4 (P<0.01) compared to the model group and Buyang Huanwutang + inhibitor group. Finally, the Buyang Huanwutang group significantly decreased ROS, MDA, and tissue iron content (P<0.01) and significantly increased GSH and SOD levels (P<0.01) compared to the model group and Buyang Huanwutang + inhibitor group. ConclusionBuyang Huanwutang inhibits ferroptosis through the GPX4/ACSL4 axis, reduces secondary neuronal and myelin injury and oxidative stress, and ultimately promotes the recovery of neurological function.

Objective:To investigate the surgical technique and initial outcomes of distal derotational femoral osteotomy (DDFO) combined with knee extension device reconstruction in adolescents with habitual patellar dislocation and severe lower limb torsional deformity.Methods:A retrospective study was conducted on 10 adolescent patients (12 knees) treated at Beijing Jishuitan Hospital and its Guizhou branch from June 2016 to June 2022. There were 6 males and 4 females with an average age of 12.0±1.5 years (range: 10.0-14.5 years) Surgical treatment included DDFO and knee extension device reconstruction (lateral retinacular release, medial retinacular plication, Roux-Goldthwait distal realignment, and MPFL reconstruction). Clinical outcomes were assessed using Lysholm scores, incidence of redislocation and complications, and imaging parameters (lateral patellofemoral angle, Insall-Salvati index, TT-TG distance, and femoral anteversion angle) preoperatively and at 1 year postoperatively.Results:All 12 knees were successfully operated on, with an average surgery time of 2.0±0.5 h (range 1.0-2.5 h), intraoperative blood loss of 47.1±17.1 ml (range 20-80 ml), and follow-up time of 46.2±18.7 months (range 24-72 months). The Lysholm knee score improved from 58.25±8.80 preoperatively to 89.17±5.32 at final follow-up ( t=-9.096, P<0.001) with significant difference. The lateral patellofemoral angle improved from -64.92±4.68 preoperatively to 6.08±2.27 at final follow-up ( t=39.178, P<0.001) with significant difference. The femoral anteversion angle decreased from 34.08±3.06 preoperatively to 14.50±2.65 at final follow-up ( t=16.916, P<0.001) with significant difference. No patellar redislocation, skin necrosis, wound infection, or limited joint mobility occurred during follow-up. Conclusion:DDFO combined with knee extension device reconstruction is an effective and safe treatment for adolescent habitual patellar dislocation with severe torsional deformity, resulting in significant clinical and radiographic improvement with low complication rates.

ObjectiveTo analyse the efficacy and mechanism of Guizhi Fulingwan in regulating sex hormone disorders in rats with benign prostatic hyperplasia (BPH). MethodsThirty male SD rats were randomly divided into a sham group, a model group, a finasteride group (0.45 mg·kg-1·d-1), and low-dose and high-dose groups of Guizhi Fulingwan (0.135, 0.337 5 g∙kg-1∙d-1), with six in each group. The BPH model was prepared by subcutaneous injection of 3.5 mg∙kg-1∙d-1 testosterone propionate after debridement surgery in all groups except the sham group. The rats in the sham group and the model group were administered with an equal volume of saline by gavage, and the rest of the groups were administered with the corresponding medicinal solution by gavage for 35 days. Histopathology in rats was evaluated by prostate wet weight, volume, index, and hematoxylin-eosin (HE) staining. The serum sex hormone levels of testosterone (T), dihydrotestosterone (DHT), and estradiol (E2) were determined by enzyme-linked immunosorbent assay. The protein expression of the androgen receptor (AR) was detected by immunohistochemistry. The serum metabolism profiles of rats in the sham group, the model group, and the high-dose group of Guizhi Fulingwan were compared by ultra-high performance liquid chromatography tandem Fourier transform mass spectrometry (UHPLCQ Exactive) to screen for metabolic markers and to obtain relevant metabolic pathways. ResultsCompared with those in the sham group, the wet weight, volume, index, serum sex hormone level, and AR protein expression of the prostate in the model group were all elevated (P<0.05, P<0.01), and the histomorphology showed pathological changes. Compared with those in the model group, the wet weight, volume, index, serum sex hormone level, and AR protein expression of the prostate in the intervention groups showed a decreasing trend (P<0.05, P<0.01), and histopathology was improved. Serum metabolomics analysis obtained a total of 40 metabolic markers related to the intervention effect of Guizhi Fulingwan, such as dehydrosafynol, hyoscyamine, and lumichrome, which were involved in the pathways of autophagy, riboflavin metabolism, and retrograde endocannabinoid signaling. ConclusionGuizhi Fulingwan can effectively regulate sex hormone disorders in BPH rats, and its mechanism may be related to autophagy, riboflavin metabolism, and retrograde endocannabinoid signaling.
