Abstract
This study aimed to establish an effective predictive model for postoperative delirium (POD) risk assessment after total knee arthroplasty (TKA) in older patients. The clinical data of 446 older patients undergoing TKA in the Orthopedics Department of our University from January to December 2022 were retrospectively analyzed, and the POD risk prediction model of older patients after TKA was established. Finally, 446 patients were included, which were divided into training group (n = 313) and verification group (n = 133). Logistic regression method was used to select meaningful predictors. The prediction model was constructed with nomographs, and the model was evaluated with correction curve and receiver operating characteristic curve. The logistic regression analysis showed that age, educational level, American Society of Anesthesiologists grade, accompaniment of chronic obstructive pulmonary disease, accompaniment of cerebral stroke, postoperative hypoxemia, long operation time, and postoperative pain were independent risk factors for POD after TKA (P < .05). The nomogram prediction model established. The area under receiver operating characteristic curve of the model group and the validation group were 0.954 and 0.931, respectively. The calibration curve of the prediction model has a high consistency between the 2 groups. The occurrence of POD was associated with age, educational level, American Society of Anesthesiologists grade, accompaniment of chronic obstructive pulmonary disease, accompaniment of cerebral stroke, postoperative hypoxemia, long operation time, and postoperative pain in TKA patients.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 333:118477. [PMID: 38909824 DOI: 10.1016/j.jep.2024.118477] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 05/29/2024] [Accepted: 06/20/2024] [Indexed: 06/25/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Premature ovarian insufficiency (POI) refers to a dramatic decrease in the number and/or quality of oocytes in the ovaries before the age of 40 years, and is a key cause of female infertility. The prevalence of POI has been increasing annually and tends to be younger. Researches on the etiology of POI and related pathogenesis are still very limited. Herbal medicine can treat many gynecological diseases. And herbal medicine is effective in reproductive health care such as infertility. In recent years, it has been found that immune modulation by cytokines (CK) can prevent or intervene in POI, and herbal medicine can treat POI by regulating CK to improve ovarian function and fertility. AIM OF THE STUDY This review presents an overview of the molecular mechanisms of regulation of POI related CK, and reports the therapeutic effect of herbal medicine on POI including herbal medicine formulas, single herbal medicine, herbal medicine active components and acupuncture. This review provides theoretical support for clinical prevention and treatment of POI, and provides new ideas for researches on herbal medicine treatment of POI. MATERIALS AND METHODS We performed a collection of relevant scientific articles from different scientific databases regarding the therapeutic effect of herbal medicine on POI by regulating CK, including PubMed, Web of Science, Wanfang Database, CNKI and other publication resources. The search terms used in this review include, 'premature ovarian insufficiency', 'premature ovarian failure (POF)', 'infertility', 'herbal medicine', 'acupuncture', 'cytokine', 'interleukin (IL)', 'tumor necrosis factor-α (TNF-α)', 'interferon-γ (IFN-γ)', 'transforming growth factor-β (TGF-β)', 'vascular endothelial growth factor (VEGF)', 'immune' and 'inflammation'. This review summarized and analyzed the therapeutic effect of herbal medicine according to the existing experimental and clinical researches. RESULTS The results showed that herbal medicine treats POI through CK (including ILs, TNF-α, INF-γ, VEGF, TGF-β and others) and related signaling pathways, which regulates reproductive hormones disorder, reduces ovarian inflammatory damage, oxidative stress, apoptosis and follicular atresia, improves ovarian pathological damage and ovarian reserve function. CONCLUSIONS This review enriches the theory of POI treatments based on herbal medicine by regulating CK. The specific mechanisms of action and clinical researches on the treatment of POI by herbal medicine should be strengthened in order to promote the application of herbal medicine in the clinic and provide new ideas and better choices for the treatment of POI.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In elderly people, Alzheimer's disease (AD) is the most common form of dementia. It has been shown that traditional Chinese medicine (TCM) based on phytomedicines enhances the therapeutic effects of modern medicine when taken in conjunction with them. Modern medicine N-methyl-D-aspartate receptor (NMDA) antagonist memantine (Mm) are mainly used in the clinical treatment of AD. TCM Cerebralcare Granule® (CG) has long been an effective treatment for headaches, dizziness, and other symptoms. In this study, we employ a blend of CG and Mm to address Alzheimer's disease-like symptoms and explore their impacts and underlying mechanisms. AIM OF THE STUDY The objective of our study was to observe the effects of CG combined with Memantine (Mm) on learning and memory impairment of AD mice induced by D-galactose and to explore the mechanism at work. MATERIALS AND METHODS CG and Mm were combined to target multiple pathological processes involved in AD. For a thorough analysis, we performed various experiments such as behavioral detection, pathological detection, proteomic detection, and other experimental methods of detection. RESULTS It was found that the combination of CG and Mm was significantly effective for improving learning and memory in AD mice as well as brain pathology. The serum and hippocampal tissue of AD mice were significantly enhanced with catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities and malondialdehyde (MDA) levels were decreased with this treatment. In AD mice, a combination of Mm and CG (CG + Mm) significantly increased the levels of the anti-inflammatory factors IL-4 and IL-10, decreased the levels of pro-inflammatory factors (IL-6, IL-1β) and tumor necrosis factor-alpha (TNF-α), improved synaptic plasticity by restoring synaptophysin (SYP) and postsynaptic density protein-95 (PSD-95) expression in the hippocampus, enhanced Aβ phagocytosis of microglia in AD mice, and increased mitochondrial respiratory chain enzyme complexes I, II, III, and IV, lead to an increase in the number of functionally active NMDA receptors in the hippocampus. Proteomic analysis GO analysis showed that the positive regulation gene H3BIV5 of G protein coupled receptor signal pathway and synaptic transmission was up-regulated, while the transsynaptic signal of postsynaptic membrane potential and regulation-related gene Q5NCT9 were down-regulated. Most proteins showed significant enriched signal transduction pathway profiles after CG + Mm treatment, based on the KEGG pathway database. CONCLUSION The data supported the idea that CG and Mm could be more effective in treating AD mice induced by D-galactose than Mm alone. We provided a basis for the clinical use of CG with Mm.

Abstract
4-Vinylcyclohexene diepoxide (VCD), an industrial occupational health hazard chemical associated with premature ovarian insufficiency (POI) and reproductive failure. Recently, investigators have paid an increasing attention on VCD model of menopause recapitulates the natural, physiological transition through perimenopause to menopause. The current study sought to examining the mechanisms of follicular loss and exploring the effect of the model on systems outside of the ovaries. In this study, 28 days female SD rats were injected with VCD (160 mg/kg) vehicle for 15 consecutive days, euthanized in the diestrus phase approximately 100 days after the onset of treatment. Reproductive system injury, Neuroendocrine, sex hormone levels and receptor were observed, the levels of N6-methyladenosine (m6A) RNA modification and the expression of modulator genes were first measured. The VCD treated rats showing irregular estrous cycles, significantly reduced in the number of primordial follicles, the preantral and antral follicles also decreased significantly, accompanied by the plasma level of FSH increased and anti-Mullerian hormone (AMH) were decreased. The total m6A level was significantly decreased after exposure to VCD. Moreover, ALKBH5-mediated YAP m6A modification changed in VCD - induced premature ovarian insufficiency. These present work provides a new perspective on m6A modification in the VCD-induced POI rat model, which could provide valuable insights into the mechanisms underlying follicle development and finding new therapeutic targets for follicle prematurely exhausted. Also provide novel methodological guidance and endocrine basis to guide research and extend the applications in premature ovarian insufficiency model.

Abstract
Premature ovarian failure (POF) is an insidious cause of female infertility and a devastating condition for women. POF also has a strong familial and heterogeneous genetic background. Management of POF is complicated by the variable etiology and presentation, which are generally characterized by abnormal hormone levels, gene instability and ovarian dysgenesis. To date, abnormal regulation associated with POF has been found in a small number of genes, including autosomal and sex chromosomal genes in folliculogenesis, granulosa cells, and oocytes. Due to the complex genomic contributions, ascertaining the exact causative mechanisms has been challenging in POF, and many pathogenic genomic characteristics have yet to be elucidated. However, emerging research has provided new insights into genomic variation in POF as well as novel etiological factors, pathogenic mechanisms and therapeutic intervention approaches. Meanwhile, scattered studies of transcriptional regulation revealed that ovarian cell function also depends on specific biomarker gene expression, which can influence protein activities, thus causing POF. In this review, we summarized the latest research and issues related to the genomic basis for POF and focused on insights gained from their biological effects and pathogenic mechanisms in POF. The present integrated studies of genomic variants, gene expression and related protein abnormalities were structured to establish the role of etiological genes associated with POF. In addition, we describe the design of some ongoing clinical trials that may suggest safe, feasible and effective approaches to improve the diagnosis and therapy of POF, such as Filgrastim, goserelin, resveratrol, natural plant antitoxin, Kuntai capsule et al. Understanding the candidate genomic characteristics in POF is beneficial for the early diagnosis of POF and provides appropriate methods for prevention and drug treatment. Additional efforts to clarify the POF genetic background are necessary and are beneficial for researchers and clinicians regarding genetic counseling and clinical practice. Taken together, recent genomic explorations have shown great potential to elucidate POF management in women and are stepping from the bench to the bedside.

Abstract
Premature ovarian insufficiency (POI) is defined as a decline in ovarian function before the age of 40 and is one of the leading causes of infertility in women. The etiology is complex, and the pathogenesis is not clear. The main treatment is hormone replacement therapy, but a growing body of data confirms that such treatment can increase the risk of endometrial disease and cardiovascular disease. Complementary and alternative medicine (CAM) has been widely used in patients with POI due to its limited adverse reactions and high efficiency. According to literature reports, CAM therapy for POI mainly includes traditional Chinese medicine, acupuncture, psychotherapy, dietary supplements, and exercise therapy. This article reviews the application of CAM in the treatment of POI and attempts to determine the therapeutic effects and the mechanisms behind these effects based on existing clinical and experimental studies in order to provide theoretical support for the treatment of POI.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huyang Yangkun Formula(HYF) is a traditional Chinese medicine formula based on the traditional theory of Yin and Yang. It could consolidate the Qi of Yin and Yang, adjust the balance of Qi and blood. It has shown clinical efficacy for patients with Premature Ovarian Insufficiency(POI). AIM OF THE STUDY Aim to access the effect of Huyang Yangkun formula (HYF) on premature ovarian insufficiency rat model and explores the mechanism related to aquaporins(AQPs) and apoptosis. MATERIALS AND METHODS Female SD rats were injected with 4-vinylcyclonhexenediepoxide(VCD, 160 mg/kg/day) for 15 days. Then, HYF (0.297 g/kg)/estradiol valerate (0.1 mg/kg) was administered for 105 days in the HYF/estradiol valerate treatment(EVT) group. Serum AMH, FSH and E2 were detected by ELISA, and the developing follicles were counted in each group.The TUNEL assay was used to detect positive apoptotic signals. IHC and western blots were used to verify differentially expressed AQPs and apoptosis-related regulators potentially associated with HYF. RESULTS Total follicles were increased significantly in the HYF group. Serum AMH was increased in the HYF group compared with MOD group. Serum FSH and E2 showed no obvious difference between HYF group and MOD group. Apoptosis occurred in POI model was proved by TUNEL and Caspase3/9 and HYF could rescue this apoptosis, besides the anti-apoptotic effect may be better than EVT. Distribution of AQPs in rat ovaries based on developmental stages of follicle was observed, and AQP8 was obviously expressed in the developing follicles and corpus luteum, particularly in granulosa cells. Upregulation of AQP8 in the MOD group and downregulation by HYF were observed. BCL-XL was significantly upregulated in the HYF group and EVT group; BCL-2 was upregulated in the HYF group with no statistical difference; MCL-1 was downregulated in the HYF group. BAX and BIM were significantly upregulated in the MOD group. The ratio of BCL-2/BAX and BCL-XL/BAX were decreased in the MOD group, and BCL-XL/BAX was increased in the HYF group and EVT group. CONCLUSION This study evaluated the treatment effect of HYF on POI in rats. It showed that HYF could promote the follicles development by regulating AQP8/Bcl-2 family-related mitochondrial apoptosis, which provides basic evidence for TCM as an alternative therapy for POI.

Cerebralcare Granule® enhances memantine hydrochloride efficacy in APP/PS1 mice by ameliorating amyloid pathology and cognitive functions. Chin Med 2021; 16:47. [PMID: 34183022 PMCID: PMC8240384 DOI: 10.1186/s13020-021-00456-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 06/08/2021] [Indexed: 01/17/2023] Open
Abstract
Background Alzheimer’s disease (AD) is a progressive neurodegenerative disease characterized by memory deficits and cognitive decline. Current drugs can only relieve symptoms, but cannot really cure AD. Cerebralcare Granule® (CG) is a Traditional Chinese medicine (TCM) containing a variety of biologically active compounds. In our previous studies, CG has shown a beneficial effect against memory impairment in mice caused by d-galactose. However, whether CG can be used as a complementary medicine for the treatment of AD remains unexplored. Here, we use a combination of CG and memantine hydrochloride (Mm) to treat Alzheimer-like pathology and investigate the effects and mechanisms in vivo. Methods The histology of brain was examined with Hematoxylin–eosin (HE) staining, Golgi staining and Thioflavin S staining. ELISA was applied to assess the expression levels or activities of CAT, SOD, GSH-Px, MDA, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL) in serum, as well as the levels of IL-6, IL-1β, and TNF-α in the mice brain. Western blotting was used to assess the expression of β-secretase (BACE1), amyloid precursor protein (APP), APPβ, APPα, synaptophysin (SYN), growth-associated protein 43 (GAP43), and postsynaptic density 95 (PSD95). Results In the present study, the combination group (CG + Mm) significantly attenuated Alzheimer-like behavior without adverse effects in APP/PS1 mice, indicating its high degree of safety and efficacy after long-term treatment. CG + Mm reduced AD pathological biomarker Aβ plaque accumulation by inhibiting BACE1 and APP expression (P < 0.05 or P < 0.001). Besides, the combination group markedly inhibited the levels of IL-1β, IL-6, and TNF-α in hippocampus (P < 0.001), as well as activities of SOD, CAT, and GSH-Px in serum (P < 0.001). By contrast, the combination group improved synaptic plasticity by enhancing SYN, PSD95, and GAP43 expression. Conclusions Taken together, these data supported the notion that CG combined with Mm might ameliorate the cognitive impairment through multiple pathways, suggesting that CG could play a role as complementary medicine to increase anti-AD effect of chemical drugs by reducing Aβ deposition, neuroinflammation, oxidative damage, and improving synaptic plasticity.

Abstract
Aims Hepatic steatosis in women confronting menopause is the manifestation of substantial fructose consumption and forms a positive feedback loop to develop endoplasmic reticulum (ER) stress. Previously pancreastatin inhibitor peptide-8 (PSTi8) and Metformin (Met) combination effectively ameliorated hepatic lipid accumulation in high fructose diet (HFrD) fed diabetic mice models at reduced doses. Moreover, SIRT-1 plays a crucial role in the regulation of SREBP-1c. Hence we hypothesized that Met and PSTi8 in combination (at therapeutic lower doses) could mitigate hepatic steatosis linked ER stress by activating SIRT-1 and precluding SREBP-1c in HFrD fed 4-Vinylcyclohexenediepoxide (HVCD) induced perimenopausal rats. Main methods HVCD rats were fed HFrD for 12 weeks, accompanied by 14 days of treatment with Met, PSTi8, and combination. We confirmed model establishment by estrus cycle study, estradiol level, and intraperitoneal glucose tolerance test. Plasma lipid profile and liver function were determined. Also, mRNA and protein expressions were examined. Moreover, distribution of SIRT-1 and SREBP-1c was detected in HepG2 cells by immunofluorescence staining. Key findings HVCD group displayed augmented insulin resistance (IR), lipogenesis, and ER stress in the liver. Combination therapy improved the estrus cyclicity, estradiol, and lipid profile of HVCD rats. Met and PSTi8 combination reduced hepatic SREBP-1c and triggered SIRT-1 expression in high fructose-induced insulin-resistant HepG2 cells; consequently, combination therapy attenuated ER stress. Significance Succinctly, present research promotes impetus concerning the remedial impact of Met with PSTi8 at lower therapeutic doses to ameliorate hepatic IR, steatosis, and associated ER stress by revamping the SIRT-1/SREBP-1c axis in perimenopausal rats.
