Non-septic shock is a serious condition leading to multiple organ dysfunction. Although targeting the mammalian target of the rapamycin complex 1 (mTORC1) signaling pathway exerts potent anti-inflammatory activity, little is known about mTORC2’s contribution to non-septic shock. Thus, our research aims to investigate mTORC2's contribution and associated changes of IκB kinase (IKKα)/inhibitor κB (IκB-α)/nuclear factor-ĸB (NF-κB) pathway on Zymosan (ZYM)-induced non-septic rat model using the novel mTORC2 selective inhibitor JR-AB2–011. Rats were given saline (4 ml/kg), dimethylsulfoxide (DMSO) (4 ml/kg), ZYM (500 mg/kg), and (or) JR-AB2–011 (1 mg/kg). Mean arterial pressure (MAP) and heart rate (HR) of rats were recorded. JR-AB2–011 reversed both ZYM-induced reduction in MAP and increase in HR. Protein expression and/or phosphorylation of rictor, protein kinase B (Akt), IκB-α, IKKα, NF-κB p65, inducible nitric oxide synthase (iNOS), nitrotyrosine, cyclooxygenase 2 (COX-2), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, besides prostaglandin (PG) E2 levels were measured. The enhanced expression of the proteins mentioned above has been inhibited by JR-AB2–011. These data suggest mTORC2’s promising role in ZYM-induced hypotension and systemic inflammation mediated via IKKα/IκB-α/NF-κB pathway.

Although numerous trials have demonstrated the benefits of purslane on patients with type 2 diabetes mellitus (T2DM), the results of some studies reject such effect. We elucidated the influence of purslane on c-reactive protein (CRP), lipid profile, and glycemic control in patients with T2DM. We conducted a systematic search on Web of Sciences, Scopus, the Cochrane Library, PubMed, and Embase, to identify studies published from their inception to February 10, 2024. The random effect model was used to calculate the combined effect, the weighted mean differences (WMDs) and its 95 % confidence interval (CI). Purslane supplementation significantly reduced fasting blood glucose (FBG) levels (WMD: −15.01; 95 % CI: −25.31, −4.71, p= 0.004), total cholesterol (TC) (WMD: −17.75; 95 % CI: −26.06, −9.45; p< 0.001), triglyceride (TG) (WMD: −21.30; 95 % CI: −32.59, −10.00; p< 0.001), low-density lipoprotein cholesterol (LDL-C) (WMD: −6.10; 95 % CI: −9.52, −2.68; p< 0.001), and CRP levels (WMD: −1.44; 95 % CI: −2.25, −0.63; p< 0.001), and increased high-density lipoprotein cholesterol (HDL-C) (WMD: 6.17; 95 % CI: 2.53, 9.80; p< 0.001). Also, purslane did not significant effect on serum levels of insulin, hemoglobin A1C (HbA1c), and homeostatic model Assessment for insulin resistance (HOMA-IR). The results of our study showed that purslane supplementation improved FBG, and lipid profile levels, but did not affect HOMA-IR, insulin, and HbA1c levels.

There is no consensus based on the existing literature regarding the effect of aged garlic extract (AGE) on blood pressure. The present systematic review and meta-analysis was conducted to synthesize existing data from randomized clinical trials (RCTs) concerning the impact of AGE supplementation on blood pressure in hypertensive patients.
Methods
We searched English web databases including, PubMed, Scopus, Embase, Web of Science until August 2024. Random-effects meta-analysis was used to pool weighted mean differences (WMD) and 95 % CI for the outcomes.
Results
Overall, nine RCTs with584 participants met inclusion criteria. AGE tea supplementation reduces systolic blood pressure (SBP) (WMD: −4.03; %95CI: −6.87, −1.20; I2: 57.1 %) and diastolic blood pressure (DBP) (WMD: −1.44; 95 % CI= −2.87, −0.02; P = 0.052; I2: 36.8 %; P: 0.105). Moreover, subgroup analysis indicated that higher doses of AGE supplementation in hypertensive patients significantly decreased DBP, and SBP.
Conclusion
The results of this study suggest that AGE supplements may be beneficial for improving blood pressure in hypertensive patients, but significant effects are observed only at doses over 1200 mg/day. To confirm these results, well-designed future trials will be needed.
背景:关于陈年大蒜提取物(AGE)对血压的影响,现有文献尚未达成共识。本系统综述和荟萃分析旨在综合现有随机临床试验(RCTs)中关于补充 AGE 对高血压患者血压影响的数据:我们检索了截至 2024 年 8 月的英文网络数据库,包括 PubMed、Scopus、Embase 和 Web of Science。采用随机效应荟萃分析法汇集结果的加权平均差(WMD)和 95% CI:共有9项研究符合纳入标准,584人参与研究。补充 AGE 茶可降低收缩压(SBP)(WMD:-4.03;95%CI:-6.87,-1.20;I2:57.1%)和舒张压(DBP)(WMD:-1.44;95%CI=-2.87,-0.02;P=0.052;I2:36.8%;P:0.105)。此外,亚组分析表明,高血压患者补充较高剂量的 AGE 可显著降低 DBP 和 SBP:本研究结果表明,AGE补充剂可能有益于改善高血压患者的血压,但只有在剂量超过1200毫克/天时才能观察到明显效果。要证实这些结果,还需要今后进行精心设计的试验。

Vitamin D has the potential to therapeutically affect the lipid profile and endocrine parameters of polycystic ovary syndrome (PCOS) patients. However, results from prior studies have been inconsistent. Therefore, we conducted an umbrella meta-analysis of randomized controlled trials (RCTs) to better understand the effectiveness of vitamin D in treating PCOS. We conducted an electronic search across multiple databases, including Embase, PubMed, Web of Science, Cochrane CENTRAL, and Scopus, from their inception to January 2, 2024. Random-effects models were used to perform the umbrella meta-analysis. The analysis included 15 meta-analyses of RCTs. Vitamin D demonstrated a significant reduction in TG levels (SMD = -0.23; 95 % CI: −0.42, −0.04, p = 0.02, and WMD = −8.76, 95 % CI: −11.81, −5.72; p <0.001), TC (SMD = −0.47, 95 % CI: −0.80, −0.13; p = 0.007, and WMD = −8.89, 95 % CI: −13.18, −4.59; p < 0.001), LDL-c (SMD = −0.24, 95 % CI: −0.38, −0.10; p = 0.001, and WMD = −3.83, 95 % CI: −6.49, −1.16; p = 0.005), TT (SMD = −0.15, 95 % CI: −0.29 to −0.01; p = 0.02), and DHEA (WMD: −28.03; 95 % CI: −56.9 to −0.36; p = 0.04). However, no significant effect on HDL-c, insulin, and BMI. The present meta-analysis revealed that vitamin D supplementation might significantly affect TG, TC, LDL-c, DHEA, and TT while it is not effective in improving BMI, HDL-c, and insulin. Vitamin D showed noteworthy effects in preventing lipid profile and enhancing hormonal function in patients with PCOS.
维生素 D 有可能对多囊卵巢综合症(PCOS)患者的血脂状况和内分泌参数产生治疗性影响。然而,之前的研究结果并不一致。因此,我们对随机对照试验(RCTs)进行了总括荟萃分析,以更好地了解维生素 D 治疗多囊卵巢综合征的效果。我们在多个数据库(包括 Embase、PubMed、Web of Science、Cochrane CENTRAL 和 Scopus)中进行了电子检索,检索时间从开始到 2024 年 1 月 2 日。采用随机效应模型进行总体荟萃分析。分析包括 15 项研究性临床试验的荟萃分析。维生素 D 能显著降低 TG 水平(SMD = -0.23;95% CI:-0.42,-0.04,p = 0.02;WMD = -8.76,95% CI:-11.81,-5.72;p = 0.05)。

Alzheimer’s disease (AD) is a degenerative disorder characterised by amyloid-beta aggregates activated by the accumulation of lipid molecules and their derivatives, especially 7-ketocholesterol (7KCh), an oxidised lipid that plays a great part in the progression of AD. The current therapeutics need bio-potential molecules and their biomedical application preventing 7KCh-induced cytotoxicity. In this study, bornyl acetate (BA) and menthol (ME), the natural monoterpenes were investigated for their neuroprotective effects against 7KCh-induced SH-SY5Y cells and their effects were compared to the standard drug galantamine (GA). 7KCh-induced changes like lipid accumulation, amyloid generation, free radical generation, acetylcholinesterase levels, calcium accumulation and mitochondrial membrane integrity were analysed in SH-SY5Y cells with or without BA and ME treatment. Furthermore, various mediators involved in the amyloidogenic, inflammatory and apoptotic pathways were studied. In our results, the cells induced with 7KCh upon co-treatment with BA and ME significantly reduced lipid accumulation and amyloid generation through toll-like receptor (TLR) 4 suppression and enhanced ATP binding cassette (ABCA) 1-mediated clearance. Co-treatment with BA and ME concurrently regulated oxidative stress, acetylcholinesterase activity, mitochondrial membrane potential and intracellular calcification altered by 7KCh-induced SH-SY5Y cells. Moreover, 7KCh-induced cells showed elevated mRNA levels of misfolded protein markers and apoptotic mediators which were significantly downregulated by BA and ME co-treatment. In addition, the protein expression of amyloidogenic, proinflammatory as well as pro-apoptotic markers was decreased by BA and ME co-treatment in 7KCh-induced cells. Overall, BA and ME mediated inhibition of amyloidogenic activation and cell survival against 7KCh-induced inflammation, thereby preventing the onset and progression of AD in comparison to GA.
阿尔茨海默病(AD)是一种退行性疾病,其特征是脂质分子及其衍生物,特别是氧化脂质 7-酮胆固醇(7KCh)的积聚激活了淀粉样蛋白-β 聚集,在阿尔茨海默病的发展过程中起着重要作用。目前的疗法需要一种具有生物潜力的分子及其生物医学应用,以防止 7KCh 引起的细胞毒性。在这项研究中,研究了天然单萜类化合物醋酸硼酯(BA)和薄荷醇(ME)对 7KCh 诱导的 SH-SY5Y 细胞的神经保护作用,并将它们的作用与标准药物加兰他敏(GA)进行了比较。研究分析了经 BA 和 ME 处理或未经 BA 和 ME 处理的 SH-SY5Y 细胞中 7KCh 诱导的变化,如脂质积累、淀粉样蛋白生成、自由基生成、乙酰胆碱酯酶水平、钙积累和线粒体膜完整性。此外,还研究了参与淀粉样蛋白生成、炎症和细胞凋亡途径的各种介质。我们的研究结果表明,用7KCh诱导的细胞经BA和ME联合处理后,通过抑制类毒素受体(TLR)4和提高ATP结合盒(ABCA)1介导的清除率,显著减少了脂质积累和淀粉样蛋白的生成。BA和ME同时处理可调节氧化应激、乙酰胆碱酯酶活性、线粒体膜电位和7KCh诱导的SH-SY5Y细胞所改变的细胞内钙化。此外,7KCh 处理的细胞显示错误折叠蛋白标记物和凋亡介质的 mRNA 水平升高,而 BA 和 ME 联合处理的细胞则显著降低了这些标记物和介质的 mRNA 水平。此外,BA 和 ME 联合处理 7KCh 诱导的细胞后,淀粉样蛋白、促炎症和促凋亡标志物的蛋白表达也有所下降。总之,BA 和 ME 可抑制淀粉样蛋白的活化,并使细胞存活,从而对抗 7KCh 诱导的炎症。此外,与GA相比,BA和ME在预防AD的发生和发展方面可能具有更好的效果。

Several studies indicated the ameliorating effects of raloxifene supplementation on apolipoproteins and blood pressure, although others have conflicting findings. Therefore, the present study was conducted in order to accurately and definitively understands the effect of raloxifene on apolipoprotein AI (Apo-AI), apolipoprotein B (APoB), lipoprotein (a) (Lp (a)), systolic blood pressure (SBP) and diastolic blood pressure (DBP) in postmenopausal women.
Methods
A systematic literature search was conducted using scientific databases including PubMed, Scopus, Embase, and Web of Science and the Cochrane Library, through May 2024. The quality of studies was assessed using Cochrane tool. Random-effects meta-analysis was used to pool standardized mean differences (SMD) and 95 % CI for the outcomes.
Results
Twenty trials, with interventions ranging from 6 to 144 weeks and 2825 participants, were included. Raloxifene supplementation demonstrated significant reductions in ApoB (SMD: −0.92; 95 % CI: −1.49 to −0.35; P = 0.001), and Lp (a) (SMD: −0.25; 95 % CI: −0.39 to −0.11; P < 0.001) while increasing Apo-AI levels (SMD: 0.29; 95 % CI: 0.22–0.36; P < 0.001). Conversely, no significant effects were observed on SBP (WMD: −0.49 mmHg; 95 % CI: −3.01–2.04; P = 0.706), and DBP (WMD: −0.81 mmHg; 95 % CI: −4.04–2.41; P = 0.621). Moreover, subgroup analysis indicated that raloxifene significantly decreased DBP in studies with intervention durations of >12 weeks.
Conclusions
This meta-analysis has shown that raloxifene supplementation may have beneficial effects on apolipoproteins in postmenopausal women. Future studies are needed to investigate the effect of raloxifene on health status in in postmenopausal women.

Aim
It was aimed to determine the potential effect of Lactobacillus acidophilus supplementation on rats exposed to an experimental high-fat diet on serum lipid profile and kidney total beta amyloid protein (TBAP) and Tumor Necrosis Factor-alpha (TNF-α) levels.
Methods
24 male Sprague-Dawley rats were used in the study to establish 4 groups. Standard rat food (SD) was provided to Group 1 as the control; Group 2 was fed a high-fat diet (HFD); Group 3 consumed SD and received L. acidophilus probiotics; Group 4 was fed HFD and received L. acidophilus probiotics. Body weights were determined weekly during the 12-week trial period. At the end of the experiment, TBP and TNF-α levels in the serum and kidney tissue of the rats were measured by ELISA method. Serum total cholesterol (TC), triglyceride (TG), HDL, LDL, urea and creatinine levels and paraoxanase, amylase and lipase activities were determined by spectrophotometric method on the analyzer device.
Results
When the control (Group 1) group and Group 2 were compared at the end of the experiment, it was found that Group 2 had gained the most weight and that both the blood and kidney tissue levels of TNF-α and TBAP, as well as the quantities of TG, TK, LDL, and urea, were significantly greater (P<0.05). Serum HDL, PON and amylase levels were found to be significantly low (P>0.05). TG, TK, LDL, urea, and the levels of TNF-α and TBAP in serum and renal tissue were shown to be lower in the groups who received L. acidophilus probiotics (Groups 3, 4) when compared to Group 2 (P>0.05). It was observed that HDL, PON and amylase levels increased and approached the control group (P<0.05).
Conclusion
The study's findings showed that probiotic supplementation improved blood levels of TG, TC, HDL, LDL, urea, PON, and amylase as well as serum and kidney tissue levels of TNF-α and TBAP in obese rats fed a high-fat diet.

Ghee, a traditional form of clarified butter, has been used for centuries in Ayurvedic medicine for its numerous health benefits. Recent scientific studies have begun to elucidate the molecular mechanisms by which ghee may support bone and joint health. This review explores the bioactive components of ghee, including short-chain fatty acids (SCFAs), medium-chain fatty acids (MCFAs), and fat-soluble vitamins (A, D, E, K2), and their potential therapeutic effects on bone density, joint lubrication, and inflammation. SCFAs in ghee can potentially improve joint lubrication and reduce inflammation. MCFAs and conjugated linoleic acid (CLA) exhibit anti-inflammatory properties, modulating cytokine production and oxidative stress pathways. Vitamins D and K2 in ghee can play potentially crucial roles in calcium metabolism and bone mineralization, while vitamin A supports immune regulation and cartilage health. This review integrates traditional knowledge with contemporary scientific research, highlighting the potential of ghee as a complementary therapy for conditions such as osteoporosis and arthritis. By understanding the molecular mechanisms involved, future studies can focus on this field to shed a light on different effects of ghee on bone and joint health.

This comprehensive systematic review and meta-analysis sought to investigate the impact of chia seed supplementation on obesity indicators and metabolic factors. Through a thorough search of relevant studies up to April 2024, 14 clinical trials involving 835 participants were included in the analysis. The findings revealed a notable decrease in triglyceride levels across both higher and lower doses of chia seeds, with weighted mean differences (WMD) of −8.69 mg/dL and −13.11 mg/dL, respectively. Additionally, a statistically significant reduction in LDL-C levels was observed solely in the higher dosage group, showing a WMD of −4.77 mg/dL. Moreover, although the decrease in systolic blood pressure (-2.78 mmHg) compared to the control group was statistically significant, it was only observed with the higher dosage. These results suggest that chia supplementation may offer beneficial effects on dyslipidemia, hypertension, and body weight, potentially mitigating the risk of cardiovascular disease.

Triple-negative breast cancer (TNBC) is a heterogeneous subtype of breast cancer that displays highly aggressive with poor prognosis. Yanghe Decoction (YHD) has been used in the treatment of breast cancer for many years. We aimed to explore the effects of YHD on the malignant phenotypes of MDA-MB-231 cells and the potential mechanism related to PPARγ, autophagy and ferroptosis. The serum of rat containing different concentrations of YHD were collected to culture MDA-MB-231 cells. Cell viability and proliferation were assessed by the CCK-8 assay and EDU staining. Wound healing- and transwell assays were used to detect the capacities of MDA-MB-231 cell migration and invasion. Additionally, the levels of lipid peroxidation, Fe2+ and the expression of ferroptosis-related proteins were evaluated. The expression of PPARγ and autophagy-related proteins was assessed using immunofluorescence staining or western blot assay. Then, the PPARγ inhibitor (GW9662), autophagy inhibitor (3-MA) and autophagy inducer (rapamycin; Rap) were used to further study the potential mechanism of YHD on TNBC. Results indicated that contained-YHD serum significantly decreased the viability, proliferation, migration and invasion of TNBC cells. Moreover, YHD promoted lipid peroxidation level, elevated Fe2+ content and downregulated GPX4, SLC7A11 and SLC3A2 expression. Besides, autophagy was induced and PPARγ was upregulated by YHD in MDA-MB-231 cells. Furthermore, GW9662 alleviated the impacts of YHD on autophagy of MDA-MB-231 cells. Rap reversed the effects of GW9662 on lipid peroxidation, ferroptosis, proliferation, migration and invasion of MDA-MB-231 cells. 3-MA had the similar effects to GW9662. Collectively, YHD suppressed the malignant progression of MDA-MB-231 cells by inducing ferroptosis through PPARγ-dependent autophagy.
