    目的:为了研究疗效,安全,nipocalimab在中度至重度活动性类风湿关节炎(RA)和对≥1种抗肿瘤坏死因子药物反应不足或不耐受的参与者中的药代动力学和药效学。
    方法:在本2a期研究中,抗瓜氨酸蛋白抗体(ACPA)或类风湿因子血清阳性的RA参与者在第0~10周被随机分为3:2组,分别接受nipocalimab(每2周1次静脉注射15mg/kg)或安慰剂.功效终点(主要终点:在第12周使用C反应蛋白(DAS28-CRP)的疾病活动评分28相对于基线的变化)和患者报告的结果(PROs)在第12周进行评估。安全,通过第18周评估药代动力学和药效学。
    结果:纳入了53名参与者(nipocalimab/安慰剂,n=33/20)。尽管nipocalimab与安慰剂的主要终点没有达到统计学意义,在第12周观察到DAS28-CRP相对于基线的数值上更高的变化(最小二乘均值(95%CI):-1.03(-1.66至-0.40)vs-0.58(-1.24至0.07)),所有次要疗效结局和PRO的改善都在数值上较高。在三名参与者中报告了严重的不良事件(烧伤感染,输液相关反应和深静脉血栓形成)。Nipocalimab显着并且可逆地降低了血清免疫球蛋白G,ACPA和循环免疫复合物水平,但不是血清炎症标志物,包括CRP。在美国风湿病学会(ACR)标准中,ACPA降低与DAS28-CRP缓解和50%缓解率相关;基线ACPA较高的参与者具有更大的临床改善。
    结论:尽管在主要终点没有达到统计学意义,Nipocalimab显示一致,中度至重度活动性RA参与者的数值疗效获益,对于基线ACPA较高的参与者观察到更大的益处。
    背景:NCT04991753。
    OBJECTIVE: To investigate the efficacy, safety, pharmacokinetics and pharmacodynamics of nipocalimab in participants with moderate to severe active rheumatoid arthritis (RA) and inadequate response or intolerance to ≥1 antitumour necrosis factor agent.
    METHODS: In this phase 2a study, participants with RA seropositive for anticitrullinated protein antibodies (ACPA) or rheumatoid factors were randomised 3:2 to nipocalimab (15 mg/kg intravenously every 2 weeks) or placebo from Weeks 0 to 10. Efficacy endpoints (primary endpoint: change from baseline in Disease Activity Score 28 using C reactive protein (DAS28-CRP) at Week 12) and patient-reported outcomes (PROs) were assessed through Week 12. Safety, pharmacokinetics and pharmacodynamics were assessed through Week 18.
    RESULTS: 53 participants were enrolled (nipocalimab/placebo, n=33/20). Although the primary endpoint did not reach statistical significance for nipocalimab versus placebo, a numerically higher change from baseline in DAS28-CRP at Week 12 was observed (least squares mean (95% CI): -1.03 (-1.66 to -0.40) vs -0.58 (-1.24 to 0.07)), with numerically higher improvements in all secondary efficacy outcomes and PROs. Serious adverse events were reported in three participants (burn infection, infusion-related reaction and deep vein thrombosis). Nipocalimab significantly and reversibly reduced serum immunoglobulin G, ACPA and circulating immune complex levels but not serum inflammatory markers, including CRP. ACPA reduction was associated with DAS28-CRP remission and 50% response rate in American College of Rheumatology (ACR) criteria; participants with a higher baseline ACPA had greater clinical improvement.
    CONCLUSIONS: Despite not achieving statistical significance in the primary endpoint, nipocalimab showed consistent, numerical efficacy benefits in participants with moderate to severe active RA, with greater benefit observed for participants with a higher baseline ACPA.

    目的:术后认知功能障碍(POCD)是一种严重的手术并发症。我们评估了七氟醚麻醉和七氟醚联合右美托咪定麻醉的不同POCD发生率。在接受胸外科手术的老年患者中使用基于丙泊酚的镇静。
    方法:共有90名年龄在65至80岁在我院接受胸外科手术的患者和15名非手术参与者作为对照,参加了这项研究。患者以1:1:1的比例随机分为3组。所有参与者被随机分为三个麻醉组(P,PS,PSD)或健康匹配的对照组(C)。所有试验组在手术期间接受不同的麻醉组合,而对照组反映了患者的标准。P组(术中维持异丙酚和瑞芬太尼),PS组(异丙酚,瑞芬太尼,和七氟醚在手术过程中保持),和PSD组(异丙酚,瑞芬太尼,七氟醚,术中维持右美托咪定)。所有参与者在手术前和手术后三天使用一系列认知评估量表进行评估。所有参与者都通过电话接受了采访,7天,30天,术后90天。
    结果:PSD的POCD发生率(异丙酚联合麻醉,七氟醚,右美托咪定)组明显低于PS(丙泊酚七氟醚联合麻醉)组,术后1天(10.0%vs.40.0%,P=0.008),术后3天结果一致。当患者被评估7天,30天,术后90天,三组的POCD发生率无显著差异.术后1天POCD的多因素logistic回归分析显示,文化程度与POCD发生率呈负相关(P=0.018),单肺通气时间与POCD发生率呈正相关(P=0.001)。
    结论:对于接受胸外科手术的老年患者,右美托咪定镇静对改善短期POCD发生率有明显优势,是由七氟烷引起的.
    OBJECTIVE: Postoperative cognitive dysfunction (POCD) is a serious surgical complication. We assessed the different POCD incidences between anesthesia using sevoflurane and sevoflurane combined with dexmedetomidine, with propofol-based sedation in elderly patients who underwent a thoracic surgical procedure.
    METHODS: A total of 90 patients aged 65 to 80 years old who underwent a thoracic surgical procedure at our hospital and 15 nonsurgical participants as controls, were enrolled in this study. Patients were divided in a randomized 1:1:1 ratio into 3 groups. All participants were randomized into a trial with three anesthesia groups (P, PS, PSD) or a control group (C) of healthy matches. All trial groups received distinct anesthetic combinations during surgery, while controls mirrored patient criteria.Group P (propofol and remifentanil were maintained during the surgery), Group PS (propofol, remifentanil, and sevoflurane were maintained during the surgery), and Group PSD (propofol, remifentanil, sevoflurane, and dexmedetomidine were maintained during the surgery).All participants were rated using a series of cognitive assessment scales before and three days after surgery. All participants were interviewed over the telephone, 7 days, 30 days, and 90 days postoperatively.
    RESULTS: POCD incidences in the PSD (combined anesthetization with propofol, sevoflurane, and dexmedetomidine) group was significantly lower than that in the PS (combined anesthetization with propofol and sevoflurane) group, 1 day post-surgery (10.0% vs. 40.0%, P = 0.008), and the results were consistent at 3 days post-surgery. When the patients were assessed 7 days, 30 days, and 90 days postoperatively, there was no significant difference in POCD incidence among the three groups. Multivariate logistic regression analysis of POCD one day after surgery showed that education level was negatively correlated with incidence of POCD (P = 0.018) and single lung ventilation time was positively correlated with incidence of POCD (P = 0.001).
    CONCLUSIONS: For elderly patients who underwent a thoracic surgical procedure, dexmedetomidine sedation shows an obvious advantage on improving short-term POCD incidence, which is caused by sevoflurane.

    背景:偏瘫肩痛(HSP)是中风后常见的并发症。严重影响上肢运动功能的恢复。偏瘫患者早期肩痛主要是由中枢神经损伤或神经可塑性引起的神经性疼痛。在肩关节中常用的皮质类固醇注射可以减轻肩痛;然而,副作用还包括软组织退化或肌腱脆性增加,长期影响仍然存在争议。肉毒杆菌毒素注射相对较新,被认为可以阻断肩关节腔中疼痛受体的传递,并抑制神经致病物质的产生,以减少神经源性炎症。有研究认为,中风后偏瘫的肩痛是由与肩关节疼痛有关的中枢系统改变引起的,持续性疼痛可能导致皮质感觉中枢或运动中枢的重组。然而,目前尚无确凿的证据表明肉毒杆菌毒素对疼痛的改善是否会影响脑功能。在以前的研究中,肉毒杆菌毒素与糖皮质激素(曲安奈德注射液)治疗肩痛,缺乏观察大脑功能变化的差异。由于以前评估疼痛改善的内容主要是主观的,缺乏客观量化的考核指标。功能性近红外成像(fNIRS)可以解决这个问题。
    方法:本研究方案是为双盲,无肱二头肌长腱鞘炎或肩峰滑囊炎的卒中后HSP患者的随机对照临床试验。78名患者将被随机分配到A型肉毒杆菌毒素组或糖皮质激素组。在基线,每组患者将接受肩部腔注射肉毒杆菌毒素或糖皮质激素,随访1周和4周.主要结果是视觉模拟量表(VAS)上的肩痛变化。次要结果是通过fNIRS成像评估相应脑区的氧合血红蛋白水平变化,肩部屈曲,外部旋转运动范围,上肢Fugl-Meyer,并修改了Ashworth分数。
    结论:超声引导下A型肉毒杆菌毒素肩关节腔注射可能为HSP患者疼痛改善提供证据。这项试验的结果也有助于分析肩痛的变化与脑血流动力学和肩关节运动功能变化之间的相关性。

    BACKGROUND: Hemiplegic shoulder pain (HSP) is a common complication after stroke. It severely affects the recovery of upper limb motor function. Early shoulder pain in hemiplegic patients is mainly neuropathic caused by central nerve injury or neuroplasticity. Commonly used corticosteroid injections in the shoulder joint can reduce shoulder pain; however, the side effects also include soft tissue degeneration or increased tendon fragility, and the long-term effects remain controversial. Botulinum toxin injections are relatively new and are thought to block the transmission of pain receptors in the shoulder joint cavity and inhibit the production of neuropathogenic substances to reduce neurogenic inflammation. Some studies suggest that the shoulder pain of hemiplegia after stroke is caused by changes in the central system related to shoulder joint pain, and persistent pain may induce the reorganization of the cortical sensory center or motor center. However, there is no conclusive evidence as to whether or not the amelioration of pain by botulinum toxin affects brain function. In previous studies of botulinum toxin versus glucocorticoids (triamcinolone acetonide injection) in the treatment of shoulder pain, there is a lack of observation of differences in changes in brain function. As the content of previous assessments of pain improvement was predominantly subjective, objective quantitative assessment indicators were lacking. Functional near-infrared imaging (fNIRS) can remedy this problem.
    METHODS: This study protocol is designed for a double-blind, randomized controlled clinical trial of patients with post-stroke HSP without biceps longus tenosynovitis or acromion bursitis. Seventy-eight patients will be randomly assigned to either the botulinum toxin type A or glucocorticoid group. At baseline, patients in each group will receive shoulder cavity injections of either botulinum toxin or glucocorticoids and will be followed for 1 and 4 weeks. The primary outcome is change in shoulder pain on the visual analog scale (VAS). The secondary outcome is the assessment of changes in oxyhemoglobin levels in the corresponding brain regions by fNIRS imaging, shoulder flexion, external rotation range of motion, upper extremity Fugl-Meyer, and modified Ashworth score.
    CONCLUSIONS: Ultrasound-guided botulinum toxin type A shoulder joint cavity injections may provide evidence of pain improvement in patients with HSP. The results of this trial are also help to analyze the correlation between changes in shoulder pain and changes in cerebral hemodynamics and shoulder joint motor function.

    伐尼克兰是戒烟最有效的唯一药物疗法。如果与尼古丁替代疗法(NRT)联合使用,戒烟率可能会进一步提高,但联合用药的疗效和安全性尚需评估.
    研究与单纯使用伐尼克林治疗的住院吸烟者相比,使用伐尼克林和NRT锭剂治疗的住院吸烟者是否获得了更高的长期戒烟率。
    双盲,安慰剂对照随机对照临床试验是在5家澳大利亚公立医院的成人内科或外科住院患者中进行的,这些患者有每天吸烟10支或更多的历史,有兴趣退出,并可在2019年5月1日至2021年5月1日期间进行12个月的随访(2022年5月的最终12个月数据收集)。数据分析于2023年6月1日至8月30日进行。
    所有参与者在住院期间以标准剂量开始了为期12周的伐尼克兰方案。如果有吸烟的冲动,参与者被随机分配使用NRT(2mg)或安慰剂锭剂。向所有参与者提供行为支持(Quitline)。
    主要结果是在6个月时经过生化验证的持续禁欲。次要结果包括自我报告的长时间禁欲,7天点患病率禁欲(3、6和12个月),和药物相关的不良事件。
    总共320名参与者(平均[SD]年龄,52.5[12.1]岁;183[57.2%]男性)被随机分组。生化验证的进行受到COVID-19限制的影响;因此,干预措施与对照组的生化验证禁欲(18[11.4%]对16[10.1%];比值比[OR],1.14;95%CI,0.56-2.33)不支持联合治疗。干预措施与对照组的次要结局为6个月时7天点的禁欲(54[34.2%]vs37[23.4%];或,1.71;95%CI,1.04-2.80),12个月时长期禁欲(47[29.9%]对30[19.1%];或,1.77;95%CI,1.05-3.00),和12个月时的7天点患病率禁欲(48[30.6%]vs31[19.7%];或,1.79;95%CI,1.07-2.99)在联合治疗下显着改善。自我报告的6个月延长禁欲(61[38.6%]对47[29.7%];或,1.49;95%CI,0.93-2.39)支持联合治疗,但无统计学意义。两组药物相关不良事件相似(干预组102例[74.5%],对照组86例[68.3%])。
    在这项针对住院成年每日吸烟者的伐尼克林和NRT锭剂组合的随机临床试验中,与单用伐尼克兰相比,联合治疗改善了自我报告的禁欲,在不损害安全的情况下,但它并没有改善生物化学验证的禁欲。

    UNASSIGNED: Varenicline is the most effective sole pharmacotherapy for smoking cessation. If used in combination with nicotine replacement therapy (NRT), cessation rates may be further improved, but the efficacy and safety of the combination need to be evaluated.
    UNASSIGNED: To examine whether hospitalized smokers treated with varenicline and NRT lozenges achieve higher prolonged smoking abstinence rates compared with those treated with varenicline alone.
    UNASSIGNED: A double-blind, placebo-controlled randomized clinical trial was conducted in adult medical or surgical inpatients of 5 Australian public hospitals with a history of smoking 10 cigarettes or more per day, interested in quitting, and available for 12-month follow-up between May 1, 2019, and May 1, 2021 (final 12-month data collection in May 2022). Data analysis was performed from June 1 to August 30, 2023.
    UNASSIGNED: A 12-week varenicline regimen was initiated during hospitalization at standard doses in all participants. Participants were randomized to additionally use NRT (2 mg) or placebo lozenges if there was an urge to smoke. Behavioral support (Quitline) was offered to all participants.
    UNASSIGNED: The primary outcome was biochemically verified sustained abstinence at 6 months. Secondary outcomes included self-reported prolonged abstinence, 7-day point prevalence abstinence (3, 6, and 12 months), and medicine-related adverse events.
    UNASSIGNED: A total of 320 participants (mean [SD] age, 52.5 [12.1] years; 183 [57.2%] male) were randomized. The conduct of biochemical verification was affected by COVID-19 restrictions; consequently, the biochemically verified abstinence in the intervention vs control arms (18 [11.4%] vs 16 [10.1%]; odds ratio [OR], 1.14; 95% CI, 0.56-2.33) did not support the combination therapy. The secondary outcomes in the intervention vs control arms of 7-day point prevalence abstinence at 6 months (54 [34.2%] vs 37 [23.4%]; OR, 1.71; 95% CI, 1.04-2.80), prolonged abstinence at 12 months (47 [29.9%] vs 30 [19.1%]; OR, 1.77; 95% CI, 1.05-3.00), and 7-day point prevalence abstinence at 12-months (48 [30.6%] vs 31 [19.7%]; OR, 1.79; 95% CI, 1.07-2.99) significantly improved with the combination therapy. The self-reported 6-month prolonged abstinence (61 [38.6%] vs 47 [29.7%]; OR, 1.49; 95% CI, 0.93-2.39) favored the combination therapy but was not statistically significant. Medicine-related adverse events were similar in the 2 groups (102 [74.5%] in the intervention group vs 86 [68.3%] in the control group).
    UNASSIGNED: In this randomized clinical trial of the combination of varenicline and NRT lozenges in hospitalized adult daily smokers, the combination treatment improved self-reported abstinence compared with varenicline alone, without compromising safety, but it did not improve biochemically validated abstinence.

    背景:钠和水潴留是导致晚期肝硬化患者腹水形成的病理生理学的支柱。顽固性腹水表示最严重的腹水状态,治疗选择有限且预后不良。我们研究了利钠肽乌利肽在难治性肝硬化腹水患者中的疗效和安全性。
    方法:我们进行了一项随机安慰剂对照试验,研究乌利肽治疗难治性腹水。直到中期分析后试验终止,我们以2∶1的比例将17名参与者随机分组,分别为ularitide(n=11)和安慰剂(n=6).住院期间,参与者接受长达48小时的治疗.主要疗效终点是肾水排泄的变化,次要终点包括肾钠排泄率和体重的变化.起始剂量为30ng/kg/min,但后来由于安全原因减少到20。
    结果:与研究假设相反,与基线水平相比,乌立肽治疗24小时后平均尿量下降(22.8vs.47.5mL/h,p=0.04),随机分配给ularitide的参与者比安慰剂减少更多(24.7vs.-6.2mL/h,p=0.05)。Ularipide不会增加肾钠排泄率或减少体重增加。乌立肽与安慰剂的不良反应发生率为8.5(95%CI:2-35,p=0.003)。接受ularitide治疗的参与者出现了严重的血压下降,影响他们的肾脏反应。
    结论:Ularitide在20-30ng/kg/min的剂量下对难治性腹水患者的尿量和肾钠排泄率没有益处。随机分配到ularitide的参与者总体上比安慰剂产生更多的不良反应。EudraCT号。2019-002268-28。
    BACKGROUND: Sodium and water retention is a mainstay of the pathophysiology leading to ascites formation in patients with advanced cirrhosis. Refractory ascites denotes the most severe ascites status with limited treatment options and a poor prognosis. We investigated the efficacy and safety of the natriuretic peptide ularitide in patients with refractory cirrhotic ascites.
    METHODS: We conducted a randomized placebo-controlled trial investigating ularitide to manage refractory ascites. Until trial termination after interim analyses, we randomized 17 participants in a 2:1 ratio between ularitide (n=11) and placebo (n=6). While hospitalized, the participants received treatment for up to 48 hours. The primary efficacy endpoint was a change in renal water excretion, and secondary end points included changes in renal sodium excretion rate and body weight. The starting dose was 30 ng/kg/min, though later reduced to 20 for safety reasons.
    RESULTS: In contrast to the study hypothesis, the mean urine production decreased after 24 hours of ularitide treatment compared with the baseline level (22.8 vs. 47.5 mL/h, p=0.04) and decreased more in participants randomized to ularitide than placebo (24.7 vs. -6.2 mL/h, p=0.05). Ularitide did not increase the renal sodium excretion rate or reduce the weight gain. The incidence rate ratio of adverse reactions in ularitide versus placebo was 8.5 (95% CI: 2-35, p=0.003). Participants treated with ularitide developed serious blood pressure reductions, impacting their renal responsiveness.
    CONCLUSIONS: Ularitide in doses of 20-30 ng/kg/min did not benefit urine production and renal sodium excretion rate in patients with refractory ascites. The participants randomized to ularitide overall developed more adverse reactions than placebo. EudraCT no. 2019-002268-28.

    免疫系统受到人类摄入的膳食产品的影响。通过营养调节免疫系统在临床上有用途,但它也可以通过延缓或预防免疫介导的慢性疾病的出现而使健康人群受益。在这项研究中,目的是描述和比较常规摄入新鲜和新鲜的调节剂对免疫系统的影响。巴氏杀菌酸奶.一个独行者,prospective,随机化,双盲,平行组进行了为期8周的营养研究,比较了每天三次健康成年人摄入125g产品的情况。一组完整的体外测试免疫系统的活性,进行了过程和现象。就增加的全身性IgM(原发性免疫反应)而言,发现新鲜酸奶相对于基线的独家免疫调节作用。刺激后IFN-γ的合成增加(Th1)和外周T细胞增加(主要是“幼稚”CD4s)。在三项干预措施中,我们观察到粒细胞的吞噬活性和爆发试验增加,以及粒细胞中IL-6,IL-1β和IL-8的分泌增加(促炎)和CD16表达增加(FcR有利于吞噬作用)。总的来说,结论是,无论细菌是活的还是热灭活的,酸奶对先天系统有共同的影响,但是活细菌的存在对于实现对特异性免疫反应的增强作用是必要的。
    The immune system is affected by the dietary products humans intake. Immune system regulation by nutrition has uses in the clinical context, but it can also benefit healthy populations by delaying or preventing the emergence of immune-mediated chronic illnesses. In this study, the purpose was to describe and compare the modulator effects on the immune system of the routine ingestion of fresh vs. pasteurized yogurt. A unicentral, prospective, randomized, double-blind, parallel group 8-week nutritional study was carried out comparing the ingestion of 125 g of the products in healthy adults three times a day. A complete battery of in vitro tests on the activity of the immune system, processes and phenomena was performed. Exclusive immune-modulatory effects of fresh yogurt with respect to base line were found in terms of increased systemic IgM (primary immune responses), increased synthesis of IFN-gamma upon stimulation (Th1) and increased peripheral T cells (mainly \"naive\" CD4s). In the three interventions, we observed an increased phagocytic activity and burst test in granulocytes, together with increased secretion of IL-6, IL-1 β and IL-8 (pro-inflammatory) and increased CD16 expression (FcR favoring phagocytosis) in granulocytes. Overall, it is concluded that regardless of bacteria being alive or thermally inactivated, yogurt has common effects on the innate system, but the presence of live bacteria is necessary to achieve a potentiating effect on the specific immune response.

    大约30%的乳蛋白是β-酪蛋白。我们旨在确定长期食用两杯A1/A2牛奶(含有75%A1β-酪蛋白和25%A2β-酪蛋白)的乳糖消化液是否会适应减少不耐受症状,较低的血清炎症标志物,和/或与消耗A2牛奶(含有100%A2β-酪蛋白)的谷胱甘肽水平相似。双盲,随机化,进行交叉试验。16个确认的乳糖消化液每天两次食用250mL的A1/A2牛奶和A2牛奶,连续两周。在第15天的适应期结束时,在用用于适应的相同牛奶(每千克体重0.5g乳糖)激发后,用氢呼气试验测量乳糖消化不良。与A2牛奶相比,在两周内食用A1/A2牛奶的粪便紧迫性更高(p=0.04,n=16)。与A2牛奶挑战相比,A1/A2牛奶在第15天的腹胀(p=0.03,n=16)和肠胃胀气(p=0.02,n=16)也更高。然而,日常症状,氢气,血清炎症标志物,A1/A2和A2牛奶消费适应期后,抗氧化剂浓度没有差异。两周内的适应并不能改善A1/A2牛奶的乳糖消化或耐受性,以匹配A2牛奶。
    Approximately 30% of milk protein is β-casein. We aimed to determine whether lactose maldigesters who chronically consumed two cups of A1/A2 milk (containing 75% A1 β-casein and 25% A2 β-casein) would adapt to have fewer intolerance symptoms, lower serum inflammatory markers, and/or altered glutathione levels similar to those consuming A2 milk (containing 100% A2 β-casein). A double-blinded, randomized, crossover trial was conducted. Sixteen confirmed lactose maldigesters consumed 250 mL of A1/A2 milk and A2 milk twice daily with meals for two weeks. At the end of the adaptation period on day 15, lactose maldigestion was measured after a challenge with the same milk used for adaptation (0.5 g of lactose per kg of body weight) with a hydrogen breath test. Fecal urgency was higher during the two-week consumption of A1/A2 milk compared to A2 milk (p = 0.04, n = 16). Bloating (p = 0.03, n = 16) and flatulence (p = 0.02, n = 16) were also higher on the 15th day with A1/A2 milk compared to A2 milk challenge. However, day-to-day symptoms, hydrogen, serum inflammatory markers, and antioxidant concentrations were not different after A1/A2 and A2 milk consumption adaptation periods. Adaptation over two weeks did not improve lactose digestion or tolerance of A1/A2 milk to match that of A2 milk.

    通过智能农场系统生产的发芽人参提取物(ThinkGIN™)已被证明可以改善临床前研究中的记忆力。这项研究进行了为期12周的随机,双盲,安慰剂对照临床试验,以评估ThinkGIN™改善主观记忆障碍(SMI)记忆的有效性和安全性。年龄在55至75岁的SMI受试者参与了这项研究。将符合纳入/排除标准的总共80名受试者分配到ThinkGIN™组(n=40,450mgThinkGIN™/天)或安慰剂组(n=40)。在干预前和干预后12周进行疗效和安全性评价。由于12周的ThinkGIN™摄入,SVLT的显著差异,RCFT,MoCA-K,PSQI-K,观察两组的AChE。安全评价(AE,实验室测试,生命体征,和心电图)显示ThinkGIN™是安全的,没有临床显着变化。因此,ThinkGIN™具有被用作改善记忆力的功能性食物的潜力。
    Sprout ginseng extract (ThinkGIN™) manufactured through a smart farm system has been shown to improve memory in preclinical studies. This study conducted a 12-week randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of ThinkGIN™ for improving memory in subjective memory impairment (SMI). Subjects aged 55 to 75 years with SMI participated in this study. A total of 80 subjects who met the inclusion/exclusion criteria were assigned to the ThinkGIN™ group (n = 40, 450 mg ThinkGIN™/day) or a placebo group (n = 40). Efficacy and safety evaluations were conducted before intervention and at 12 weeks after intervention. As a result of 12 weeks of ThinkGIN™ intake, significant differences in SVLT, RCFT, MoCA-K, PSQI-K, and AChE were observed between the two groups. Safety evaluation (AEs, laboratory tests, vital signs, and electrocardiogram) revealed that ThinkGIN™ was safe with no clinically significant changes. Therefore, ThinkGIN™ has the potential to be used as a functional food to improve memory.
