ObjectiveTo explore the mechanism of Yishen Huashi granules in alleviating renal tubular epithelial cell injury and relieving diabetic kidney disease by regulating the mitogen-activated protein kinase (MAPK) signaling pathway. MethodsThe db/db mice of 12 weeks old were randomly assigned into model , dapagliflozin (1.6 mg·kg-1), and Yishen Huashi granules (4.7 g·kg-1), and db/m mice were used as the control group. The general conditions of mice were observed, and fasting blood glucose and 24-h urinary protein and albumin-to-creatinine ratio (ACR) were measured at weeks 0 and 12 of administration. After 12 weeks of treatment, the levels of serum creatinine (SCr), blood urea (UREA), triglycerides (TG), total cholesterol (TC), and low density lipoprotein (LDL) were measured. The pathological changes in the renal tissue were observed by hematoxylin-eosin (HE) staining, Periodic acid-Schiff (PAS) staining, Mallory staining, and transmission electron microscopy. Real-time PCR was employed to determine the mRNA levels of monocyte chemotactic protein-1 (MCP-1) and CC chemokine receptor-2 (CCR2) in the renal tissue of mice. The immunohistochemical assay was employed to examine the expression of p38, phospho-p38 (p-p38), MCP-1, and CCR2 in the renal tissue of mice. Western blotting was employed to measure the protein levels of p-p38, p38, MCP-1, and CCR2 in the renal tissue of mice.HK-2 cells cultured in vitro were grouped as follows: negative control, high glucose(30 mmol·L-1), Yishen Huashi granule-containing serum, and SB203580. After 48 h of cell culture in each group, RNA were extracted and the levels of MCP-1, and CCR2 mRNA were determined by Real-time PCR,proteins were extracted and the levels of p38, p-p38, MCP-1, and CCR2 were determined by Western blot. ResultsThe in vivo experiments showed that before treatment, other groups had higher body weight, blood glucose level, 24 h urinary protein, and ACR than the control group (P<0.05,P<0.01). After 12 weeks of treatment, compared with the model group, the Yishen Huashi granules group showed improved general conditions, a decreasing trend in body weight, lowered levels of blood glucose, 24-h urinary protein, and ACR (P<0.01), reduced SCr and UREA (P<0.01), and declined levels of TC, TG, and LDL (P<0.05,P<0.01). Compared with the model group, the Yishen Huashi granules group showed alleviated damage and interstitial fibrosis in the renal tissue as well as reductions in glomerular foot process fusion and basement membrane thickening. Moreover, the Yishen Huashi granules group showed down-regulated mRNA levels of MCP-1 and CCR2 (P<0.01), reduced positive expression of p-p38, MCP-1, and CCR2 (P<0.01), and down-regulated protein levels of p-p38/p38, MCP-1, and CCR2 (P<0.05) in the renal tissue. The cell experiment showed that compared with the high glucose group, the Yishen Huashi granule-containing serum group showcased down-regulated mRNA levels of MCP-1 and CCR2 (P<0.01) and down-regulated protein levels of p-p38/p38, MCP-1, and CCR2(P<0.05,P<0.01). ConclusionYishen Huashi granules can regulate glucose-lipid metabolism, reduce 24 h urinary protein and ACR, improve the renal function, alleviate the renal tubule injury caused by high glucose, and protect renal tubule epithelial cells in db/db mice by reducing MCP-1/CCR2 activation via the p38 MAPK signaling pathway.

ObjectiveTo observe the effects of electroacupuncture with "tonifying the kidney and dispelling stasis" acupoint prescription on sexual function in diabetic erectile dysfunction (DMED)model rats, and to explore its possible mechanism of action. MethodsSPF male SD rats were randomly divided into 10 each in blank group, model group, Tadalafil group, and electroacupuncture group. DMED rat model was prepared by high glucose and high fat diet combined with intraperitoneal injection of streptozotocin. After successful modelling, rats in the electroacupuncture group were given electroacupuncture intervention of "tonifying the kidney and dispelling stasis" acupoint prescription once every other day; Tadalafil group was given Tadalafil solution 0.5 mg/kg·d by gavage, and the blank group, model group and electroacupuncture group were given 10 ml/kg pure water by gavage once a day. Each group was intervened for 30 days. The body mass and blood glucose level of the rats were detected on the 1st, 8th, 15th, 22nd days and at the end of the intervention, respectively. At the end of the intervention, the penile erection of the rats was observed by using the apomorphine test; the level of plasma endothelial cell microparticles (EMPs)was detected by flow cytometry; the histopathological morphology of the penile cavernous body was observed by HE staining, and the pathological morphology of the endothelial cells of the penile vasculature was observed by electron microscopy. Serum sex hormones including testosterone (T), follicle stimulating hormone (FSH), luteinising hormone (LH) and vascular endothelial function-related factors including vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), soluble E-selectin (sE-selectin), and soluble intercellular adhesion molecule-1 (sICAM-1) were measured by ELISA method. ResultsCompared with blank group, the model group, Tadalafil group, and electroacupuncture group all had lower body mass and higher blood glucose levels at each time of testing (P<0.01). Compared with the blank group, the number of penile erections reduced in the model group, the level of CD31+ EMPs increased, the levels of serum T, FSH, LH, and VEGF reduced, and the levels of serum ET-1, LOX-1, sE-selectin, and sICAM-1 increased (P<0.01). Compared with the model group, the Tadalafil group and the electroacupuncture group showed an increased number of penile erections decreased level of CD31+ EMPs, increased levels of serum T, FSH, LH, and VEGF, and decreased levels of serum ET-1, LOX-1, sE-selectin, and sICAM-1 (P<0.01). Compared with the Tadalafil group, serum T, FSH, LH, VEGF levels increased and ET-1, LOX-1 levels decreased in the electroacupuncture group (P<0.05 or P<0.01). HE staining and electron microscopic observation revealed that there was severe pathological damage to the cavernous tissue of the penis and vascular endothelial cells of the rat in the model group, which was ameliorated to a certain degree in both Tadalafil group and electroacupuncture group. ConclusionThe electroacupuncture prescription of "tonifying the kidney and dispelling stasis" can improve the erectile dysfunction of DMED rats, which is comparable to the effect of Tadalafi. Its mechanism of action may be related to the regulation of vascular endothelial function.

BACKGROUND:
A growing body of research is exploring the role of antioxidant and anti-inflammatory dietary supplements in the treatment of osteoarthritis, highlighting an increasing emphasis on non-pharmacological interventions. Although more patients are turning to supplements to manage osteoarthritis, their actual effectiveness remains uncertain.
OBJECTIVE:
This study aims to provide a comprehensive evaluation of the available evidence concerning the efficacy of various dietary supplements in osteoarthritis treatment.
SEARCH STRATEGY:
We searched PubMed, Embase, Cochrane Library and Web of Science for studies on the use of various dietary supplements in the treatment of osteoarthritis from the creation of each database until Jan 20, 2025.
INCLUSION CRITERIA:
(1) Research object: osteoarthritis. (2) Intervention measures: patients in the treatment group received dietary supplements, while the control group received placebos. (3) Research type: randomized controlled trials (RCTs).
DATA EXTRACTION AND ANALYSIS:
Two researchers independently examined the literature and retrieved data based on predefined criteria. The information gathered included the first author, year of publication, sample size, participant demographics, length of the follow-up period, intervention and control measures, and inclusion indications. RCTs comparing dietary supplements to placebo with the pain and function subscales of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) among patients with osteoarthritis were included. The optimal dietary supplement was identified based on the total ranking by summing the surface under the cumulative ranking curve (SUCRA) of these two scores. Furthermore, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to confirm the quality of the evidence.
RESULTS:
Overall, 23 studies covering 21 dietary supplements and involving 2455 participants met the inclusion criteria. In the WOMAC pain score, the SUCRA of passion fruit peel extract was 91% (mean difference [MD]: -9.2; 95% confidence interval [CI]: [-16.0, -2.3]), followed by methylsulfonylmethane (89%), undenatured type II collagen (87%), collagen (84%), and Lanconone (82%). The SUCRA (99%) of passion fruit peel extract (MD: -41.0; 95% CI: [-66.0, -16.0]) ranked first in terms of the WOMAC function score, followed by Lanconone (95%), collagen (86%), ParActin (84%), and Lactobacillus casei strain Shirota (83%). The top three total rankings are passion fruit peel extract (95.0%), Lanconone (88.5%), and collagen (85.0%). However, the GRADE revealed low evidence quality.
CONCLUSION
Passion fruit peel extract was the best supplement for improving WOMAC pain and function scores in patients with osteoarthritis, followed by Lanconone and collagen. However, further large-scale, well designed RCTs are required to substantiate these promising findings.

Objective:To evaluate the training efficacy of the autonomic nervous system stability assessing and enhancing capsule (hereinafter referred to as the EC), and to study the difference in physiological indicators for autonomic nervous system stability training between the EC and a non-capsule environment.Methods:A total of 1 478 male military pilots under autonomic nervous system stability training between February 2022 and February 2024 were selected before they completed training sessions in both the EC and a non-capsule environment. The pre-training time-domain and frequency-domain indices of heart rate variability (HRV) and the 0.1 Hz index were compared with the post-training ones, and across difficulty levels (low, moderate, and high). The difference that the EC made in relaxation training was analyzed.Results:①Time-domain indices of HRV were of statistical significance in the main effects of training difficulty, those of training environments, and their interactions ( F=4.40-160.80, all P<0.05 or 0.01). Simple effect analysis revealed that in the same phase of training the standard deviation of all NN intervals (SDNN) at the low level of difficulty in the EC was lower than in the non-capsule environment. However, all time-domain indices after training were higher in the EC than in the non-capsule environment. The differences were statistically significant (all P<0.05 or 0.01).②For frequency-domain HRV indices, significant differences were observed in both the main effect of training difficulty and the interactions ( F=4.40-1 524.33, all P<0.01). Very low frequency power (VLF), high frequency (HF), the ratio of low frequency to high frequency (LF/HF), normalized low frequency (LFnorm), and normalized high frequency (HFnorm) were significantly different in the main effect of training environments ( F=4.24, 12.00, 6.91, 23.39, 23.39, P=0.040, <0.001, =0.009, <0.001, <0.001). Simple effect analysis revealed that at the same level of training difficulty, the EC delivered significantly lower values of LF and LFnorm but higher values of HF and HFnorm than the non-capsule environment before training (all P<0.05). VLF across levels of training difficulty and LF/HF at the high level of difficulty level were significantly lower in the EC than in the non-capsule environment. After training, total power, VLF, LF, HF, and HFnorm were significantly higher in the EC than in the non-capsule environment, but LF/HF and LFnorm were significantly lower (all P<0.05). ③For the 0.1 Hz index, significant differences were observed in both the main effect of training difficulty and the interactions ( F=2 147.75, 6.63, both P<0.001). Subsequent simple effect analysis revealed that at the same level of training difficulty, 0.1 Hz indices of pilots in the EC were lower than in the non-capsule environment before and after training (all P<0.01). Conclusions:During the autonomic nervous system stability training, the EC can effectively and quickly regulate and alleviate pilots′ fatigue and stress. Furthermore, it provides sustained autonomic nervous system training, thereby stabilizing pilots′ autonomic nervous system.

Objective:To investigate the expression of miR-769-5p in serum exosomes of epithelial ovarian cancer(EOC)and its mechanism of influence on EOC cell proliferation,migration,and invasion.Methods:The expression level of miR-769-5p in serum exosomes from the malignant group,benign ovarian disease group,and healthy control group was detected using reverse transcription quantitative polymerase chain reaction(RT-qPCR).Lipofectamine 3000 transfection was used to construct overexpression and knockdown cell lines,which were divided into four groups:miR-769-5p mimics group,mimics-NC group,miR-769-5p inhibitor group,and inhibi-tor-NC group.The effects of miR-769-5p on cell proliferation,migration,and invasion were assessed using CCK-8,wound healing,and Transwell assays.Transcriptome sequencing was conducted on EOC cells overex-pressing miR-769-5p,and potential target genes were predicted using public databases.The interaction between miR-769-5p and its target gene was validated by dual-luciferase reporter assay.RT-qPCR and Western blotting were used to further confirm the regulatory effect of miR-769-5p on the target gene.Results:The expression level of miR-769-5p in serum exosomes from the malignant group was significantly lower than that in the healthy control and benign ovarian disease groups(P<0.05).Compared with the mimics-NC group,the miR-769-5p mimics group exhitied lower OD450 values,migration rates,and numbers of invading cells in both SKOV3 and OVCAR3 EOC cell lines(P<0.05).Compared with the inhibitor-NC group,cells in the miR-769-5p inhibitor group exhibited increased OD450 values,migration rates,and invasion counts(P<0.05).The dual-luciferase reporter assay showed that co-transfection of miR-769-5p mimics with pEZX-FR02-TFAM-WT significantly reduced the luciferase activity compared to the mimics-NC group(P<0.01),whereas co-transfection of miR-769-5p mimics with pEZX-FR02-TFAM-MUT showed no significant difference in luciferase activity compared to the control(P>0.05).These findings indicate that miR-769-5p can directly bind to the 3'-UTR region of TFAM.Furthermore,compared with the mimics-NC group,EOC cells transfected with miR-769-5p mimics showed significantly decreased TFAM mRNA and protein expression levels(P<0.05).Conclusion:miR-769-5p is significantly downregulated in EOC serum exosomes and may serve as a promising biomarker for early tumor diagnosis.Moreover,miR-769-5p may inhibit the proliferation,migration,and invasion of ovarian cancer cells by targeting TFAM.

Objective:To investigate the clinical efficacy of combination of a Flow-through anterolateral thigh myocutaneous flap with a contralateral great saphenous vein grafting in reconstruction of Gustilo ⅢC foot and ankle injury in emergency surgery.Methods:This retrospective study analysed the clinical data of 9 patients who were admitted in the Department of Wound Repair Surgery, Suzhou Ruihua Orthopaedic Hospital between September 2021 and October 2023. All patients were diagnosed with Gustilo ⅢC foot and ankle injury and met the predefined inclusion criteria. The average age of the patients was 45 (26-64) years. The mean of Mangled Extremity Severity Score (MESS) was 8.2 points, with a range from 5 to 10 points. The wound area after debridement ranged from 15.5 cm×6.0 cm to 24.5 cm×12.5 cm, with the vascular occlusion or defect at 4.0-20.0 (mean, 6.3) cm in length. The size of the flap was 16.5 cm×7.0 cm-25.5 cm×13.5 cm. During surgery, segments of the great saphenous vein were excised in the length of 5.0-21.0 cm, at an approximately 6.5 cm in length. The Flow-through anterolateral thigh myocutaneous flap was employed to reconstruct the soft tissue defect and to establish vascular connections between the anterior or posterior tibial arteries and veins, with the vessels carried by the flap. Additionally, the contralateral great saphenous vein was taken to bridge the posterior or anterior tibial arteries and veins. Follow-ups were carried out by outpatient visits, telephone calls and WeChat interviews. The flap viability, limb blood circulation, wound healing at both donor and recipient sites, as well as functional recovery of the affected limbs was observed. Sensation recovery of the flap was assessed according to the rating standard established by the British Medical Research Council (BMRC) , while the function recovery of foot and ankle was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scale.Results:All flaps successfully survived without vascular complication. Eight affected limbs were effectively cured, while a calf that had an infection and necrosis of a long segment of tibia and fibula was amputated below-the-knee in the stage-II surgery. One of the donor sites of flap was covered with a medium-thickness skin graft from lower abdomen due to the large size of the flap, while the other donor sites were directly sutured and healed at first intention. One patient developed postoperative bone infection, which was successfully treated through re-debridement and antibiotic bone cement filling. Another patient experienced partial necrosis at the distal hallux due to a prolonged limb ischemia, and a stump repair surgery was performed. All patients were entered into the postoperative follow-up for 15.3 (6-24) months. At the final follow-up visit, satisfactory colour and texture were observed on all flaps, although minor oedema was present. Donor sites healed well and the donor limb function was not affected. Sensory evaluation rated S 2 in 5 flaps and S 3 in 3 flaps according to BMRC. Functional assessment of foot and ankle of the affected limb yielded excellent in 2 patients, good in 5 patients and fair in 1 patient according to AOFAS. Conclusion:Flow-through anterolateral thigh myocutaneous flap combined with a contralateral great saphenous vein grafting enables one-stage reconstruction for soft tissue defect and blood circulation of the affected limb. It is a good method in the treatment of Gustilo ⅢC foot and ankle injury in emergency surgery.

Objective:To investigate the changes in thyroid hormone levels and inflammatory markers in critically ill children,analyze their correlation with disease severity,and explore their potential impact on prognosis,providing references for clinical management and prognosis assessment in critical illness.Methods:A retrospective cohort study was conducted involving 394 pediatric patients admitted to the ICU of the Capital Pediatric Institute Affiliated Children's Hospital from 2019 to 2023.Based on the pediatric critical illness score,patients were divided into three groups:the extremely critical group (score ≤ 70, n=81),the critical group (score 71–80, n=150),and the non-critical group (score>80, n=163).Data collected included thyroid function indicators,inflammatory markers[C-reactive protein(CRP),procalcitonin(PCT),tumor necrosis factor(TNF)-α,interleukin (IL),etc.],clinical information,and outcomes.The correlation between thyroid function indicators and inflammatory markers were analyzed.The predictive value of thyroid function indicators and inflammatory markers for prognosis in critically ill pediatric patients was assessed. Results:Of the 394 children,non-thyroidal disease syndrome occurred in 321 cases,with an overall incidence of 81.5%,which increased with disease severity.Thyroid hormone [total triiodothyronine (TT3),free triiodothyronine (FT3),and total tetraiodothyronine (TT4)] levels were significantly lower in the extremely critical group than in the other groups ( P<0.05).Inflammatory markers such as CRP,PCT,TNF-α,IL-6,IL-8,and IL-10 were significantly higher in the extremely critical group than in the other groups ( P<0.05).Thyroid hormones were negatively correlated with inflammatory markers,and the receivor operating characteristic curves analysis indicated that TT3,FT3,IL-6 and IL-8 levels,could effectively differentiate disease prognosis.Univariate regression model showed significant associations between TT3,FT3,TT4,PCT,IL-8,and IL-10 and disease prognosis.The multivariate Logistic regression model showed IL-6 and IL-8 were independent predictors of disease prognosis. Conclusion:Significant reductions in thyroid hormone levels are closely related to disease severity and poor prognosis.Changes in inflammatory markers reflect the inflammatory state and severity of the disease and impact prognosis.Monitoring thyroid function and inflammatory status is important in clinical management,which provids new insights into prognosis assessment and treatment strategies for critically ill children.
